Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a device that allows selection of any water depth when taking agricultural water from a dam, water storage area, or the like.

[Prior Art] As a conventional technology of a selective water intake device, there is a "selective water intake device" (Japanese Utility Model Publication No. 16661/1983) which was devised by the applicant himself.

This technology involves arranging multiple stages of gate bodies in a row along the top and bottom facing the water conveyance direction of the water intake, and adjoining each other vertically so that an opening of the desired size is formed between the gate bodies. This selective water intake device includes a connecting means that interposes a common connecting tool between the door bodies, and a hoisting means that is located above the door body and lifts the door body.

To explain this technique in detail based on an example, as shown in FIGS. 7A, B, and C, a plurality of door bodies 1a, 1b, 1c...
At 7c..., a wire rope 35 is attached which is connected to each of the vertically extending door bodies and is further wound around a hoisting device (not shown) that lifts the upper end of the door group.

In FIG. 7A, the gate bodies 1a, 1b, 1c... hang down in a line in the water conveyance direction of the water intake section facing the dam body 36, blocking water and creating a gap between the topmost door body 1a and the water surface. Surface water near the water surface is taken from the first opening Oo and introduced into the water conduit pipe 37. When the hoisting device is driven here and lifted, the topmost door opens as shown in Figure 7B. The body is lifted up, and the first connector 7a, which is loosely fitted and connects the door bodies so that it can rise and fall, moves inside the second door body 1b, opening a new opening Oa.
The water intake is introduced from here.

When lifted further, the same effect occurs on the third door body 1c.
The second connector 7b is lifted up to form a new opening Ob.

There are two openings in the water intake section, but
Due to the difference in density with water depth, water is selectively passed through the opening Ob located in the lower layer.

The door bodies arranged in a row in this way are lifted one by one from the top to form an opening between the door bodies, and from the opening at the bottom of this opening, the water inside and outside the door bodies is drawn using the density difference. Water can be taken arbitrarily and selectively, and the appropriate water quality can be obtained taking into account water temperature and turbidity (after floods, heavy rains, etc.).

[Problems to be Solved by the Invention] There are no particular problems with the above technology, and it can bring significant benefits as a basic technology.

However, in implementation, technical benefits will be further increased by disclosing supplementary details.

The problem here is that it is necessary to inspect each of the plurality of door bodies arranged in a row.

Inspections must be carried out periodically even in the case of a single door body, but in the case of a structure in which a plurality of door bodies are connected via a connector, it is an unavoidable maintenance requirement.

If it becomes clear how to carry out the inspection, the above-mentioned prior art can further increase the practical benefits.

The purpose of the present invention is to provide a basic inspection system and several embodiments that more specifically show this system in response to the question of how to inspect in order to solve the above problems. do.

[Means for Solving the Problems] The selective water intake device according to the present invention includes an inspection room provided directly above the door group, two sets of hoisting devices installed above the inspection room, and the uppermost door By making it possible to independently roll up the door body and the lowest door body, it is possible to separate a row of door bodies in the inspection room into single door bodies and hang them individually. The above-mentioned problem was solved by providing means for connecting the suspended single door bodies in a row to restore the original door group.

Breaking this down into specific embodiments and showing it in more detail, the connecting means has two pins, upper and lower, protruding from both sides of each door body, and the lower pin of the adjacent upper door body is connected. The upper pin of the lower door body is inserted into the upper circular hole of the tool, and the upper pin of the lower door body is inserted into the lower elongated hole of the same connector.

Furthermore, three embodiments are shown here as means for separating the rolled-up door group into individual door bodies in the inspection room.

The first method is to drill a through hole in the lower side wall of both sides of each door body and insert the lower pin into it.The outer extension of the lower pin is inserted into the upper circular hole of the connector, and the inner end on the door body side is operated. The two operating rods on the left and right are bendably connected to the rod, and the two left and right operation rods are flexible and loosely fitted to a lever in the center of the door body, and the lever is configured to lock with the door body so that it can be turned upside down.

The lower pin, which is removably attached to the lower part of both sides of each of the second door bodies, is inserted into the upper circular hole of the connector outside the door body, and the operating rod is fixed to the outer end of the lower pin. A flange is provided on the other end, and the flange fits into a guide groove recessed in the door groove so as to be able to move up and down, and the guide groove curves outward near the lower part of the inspection chamber.

The third method is to drill a through hole in the lower side wall of both sides of each door body and insert a lower pin into it.The outer end of the lower pin is inserted into the upper circular hole of the connector, and the inner end on the door body side is inserted into the upper circular hole of the connector. It is fixed to the operating rod, and the operating rod can be bent freely within the door body.
The lever is loosely fitted in a T-shape with the book lever, and is biased by an elastic body in the direction of pulling out the lower pin at its tip. The doors are biased in a direction opposite to the biasing force through the gates, so that they are flattened at the intersection point, and the side surfaces of the door grooves are configured to retreat outward near the lower part of the inspection chamber.

As shown in these three examples, the lower pin of each door body is removed from the upper circular hole of the connector, the door body is removed from a row of door bodies, and each separated door body is then reversed after inspection. The original door body group will be restored through the following steps.

[Operation] Figures 1A and 1B are front and side views showing an embodiment of the present invention, and in this example, the door body is 1
The case is shown in which there are three wires A, 1B, and 1C.

A first hoisting device 3 and a second hoisting device 4 are provided in the inspection room.

The first hoisting device hoists the first door body 1A, and the second hoisting device hoists the lowest door body (here, 1c) with a wire rope.

Since the first and second devices are capable of independently hoisting, when the second hoisting device 4 is first driven, only the door body 1c is hoisted up, filling the opening O _B located directly above it. When the door bodies 1B and 1C are connected and further rolled up, the opening O _A is also filled and the door bodies are all continuous.

In this way, when the entire door group is supported from the bottom by the hoisting device 4, and then the first hoisting device 3 is driven, only the uppermost door body 1A is separated and hoisted up. This can be placed horizontally in the inspection room, and each of the door bodies positioned at the top one after another can be rolled up individually and hung separately in the inspection room.
