Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underground buried facility having a waterproof function, such as a control panel for a manhole pump, and more particularly to a heat radiation structure for the facility.

[0002]

Sewage from factories / household wastewater, rainwater, etc. is sent to a sewage treatment plant by utilizing the height difference of the sewer, but it is difficult to maintain this height difference over a long distance. The height difference is adjusted by pumping up sewage with a manhole pump in a manhole provided at a predetermined interval. In general, a control panel that controls the operation of the manhole pump is attached to a pillar such as concrete built on the ground. However, since the control panel requires a certain installation space, if the control panel is attached to a pillar built on the sidewalk, it may hinder the passage of pedestrians and the like.

For this reason, when installing the control panel for the manhole pump, there are cases in which the mounting columns for mounting the control panel must be built on a nearby private land instead of being built on a sidewalk or the like. In this case, it is not always possible to obtain the approval of the owner of the private land, and under such circumstances, it has been proposed to bury the control panel of the manhole pump underground.

However, when the control panel of the manhole pump is buried underground, it is necessary to take waterproof measures such as making the control panel waterproof in preparation for flooding such as heavy rain, but conventional waterproof measures are expensive. Since the waterproof shield structure is formed by using the waterproof member, there is a problem that the manufacturing cost and the installation cost of the control panel increase. So, as a solution,
The underground burying device such as the control panel is covered with a storage container from above, and even if the hole for the underground burying facility is submerged by the air sealed in the storage container, a waterproof function is provided so as to prevent water from entering the underground burying device. The provided underground burial facility is put to practical use.

The structure of this conventional underground buried facility having a waterproof function will be described with reference to FIG. FIG. 2 is a vertical sectional front view showing a schematic configuration of the underground burial facility 50. In the figure, 51 is a control panel of a manhole pump (not shown) which is an underground burying device, and the control panel 51 is supplied with electric power from a power source (not shown) via a power cable 52.
Although not shown, the operation of the manhole pump is controlled according to the water level in the manhole detected by the water level detector installed in the manhole. Also, 55
Is a storage container for storing the control panel 51 from above, and a hole for burying the control panel 51 is dug from the ground GR to a depth of about 1 to 2 m in the ground, and the sediment collapses on the inner peripheral surface and the bottom surface of the hole. There is provided an inner wall 60 called a handhole for preventing the intrusion of groundwater and the like.

Reference numeral 53 is a hook for lifting the control panel 51 of the manhole pump in a storage container 55 and installing it in the inner wall 60 with a crane or the like. The control panel 51 is fixedly supported by a support tool 56 attached to the lower portion of the storage container 55. 57 is a storage container 55
The support table of FIG. 6 fixedly supports the storage container 55 so as not to swing. For maintenance and inspection of the control panel 51, the storage container 5
5 is removed from the support base 57, the control panel 51 is attached to the support 56
In the state of being fixedly supported in the storage container 55, the storage container 55 is lifted by the hook 53 by a crane or the like, and then the control panel 51 is taken out from the storage container 55 to perform maintenance work such as maintenance and inspection. The inner wall 60 has a lid 6
1 is covered to prevent the fall of pedestrians and the inflow of rainwater. Reference numeral 62 denotes a drainage facility including a drainage port 62a, a drainage pipe 62b, a gas intrusion prevention drainer trap 62c, and the like, and discharges water that has entered the inside of the inner wall 60 to a manhole via the drainage pipe 62b.

In the above structure, the ground GR on which the underground burying equipment is installed is flooded due to heavy rain or flood, and the inner wall 60
Even if water enters the inside and the inside of the inner wall 60 is submerged due to the lack of drainage by the drainage facility 62, the storage container 55
Since the air inside is not trapped inside the storage container 55 and leaks out to the outside, it is possible to prevent the intrusion of water by the internal pressure of the air and prevent the main part of the control panel 51 from being flooded. In addition, the power cable 52 is also provided below the control panel 51.
Since there is a portion such as a connector 58 that needs insulation, the storage container 55 has a deep bottom shape for storing the control panel 51 so as to cover the lower portion of the control panel 51 almost completely. There is.

Therefore, the control panel 51 is not covered with a special waterproof member or the like so that the structure is not completely waterproof.
The control panel 51 can be protected from water intrusion by a simple method of covering the entire control panel 51 with a cover from above. With the underground burial facility equipped with such a waterproof structure, it is possible to significantly reduce the installation cost of the underground burial device and reliably prevent the underground burial device such as the control panel 51 from being flooded.

[0009]

By the way, as described above, in the conventional underground burial facility having a waterproof function, the storage container for accommodating the underground burial device from above should cover the underground burial device almost completely. The bottom that houses the lower part of the underground burying device has a deep shape. However, if the storage container has this shape, the air permeability of the storage container will deteriorate,
Dissipation of heat generated when the underground burial equipment is operating may be poor, which may cause a failure of the underground burial equipment. An object of the present invention is to solve the above problems (problems) and to provide an underground burying facility having a waterproof function, which has a storage container excellent in heat dissipation.

[0010]

In the underground burying equipment having a waterproof function of the present invention, basically, as described in claim 1, the underground burying equipment is stored in a storage container, and the underground burying equipment is installed in the underground burying equipment. In the underground burial facility having a waterproof function for preventing the infiltration of water, the storage container is formed in a heat dissipation structure by providing one or more heat dissipation fins on the head of the storage container. An underground burial facility equipped with a waterproof function, and, more specifically, as described in claim 2, the underground burial device is covered with an accommodating container from above and accommodated, and air is sealed inside the accommodating container. Thus, in the underground burial facility equipped with a waterproof function for preventing water from entering the underground burial device, by providing one or more radiating fins on the head of the storage container, the storage container becomes a heat dissipation structure. To form It was. By doing so, the heat dissipation that occurs when the underground burying device stored in the storage container is in operation is improved with a simple structure, and it becomes possible to prevent breakdowns and the like due to overheating of the underground burying device.
