Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a water supply unit storage box for accommodating a water supply unit for supplying water stored in a water receiving tank to a place where water is used by driving a booster with a control device.
It is about the space.

[0002]

2. Description of the Related Art In the water supply unit as described above, a submersible pump or a land pump is used as a booster. In a water supply unit that uses a submersible pump as a booster, a piping unit including a control device, a detection unit, and valves is installed flat on the bottom of the water tank or on the floor near the side surface. A water supply unit that uses a land pump as a booster is also installed on the floor below the water tank or near the side surface, including the land pump.

[0003]

In the conventional water supply unit, since each component is installed in a plane, a wide installation space is required. When the submersible pump is used, the heat generated from the motor unit due to the operation of the submersible pump is radiated to the water in the water receiving tank, so that the water in the water receiving tank can efficiently cool the motor unit.

However, when the land pump is used, in order to efficiently dissipate the heat generated from the motor section to the atmosphere by operating the land pump, the motor casing is made of a good heat conductor, and the motor casing is provided with cooling fins. A large number of ventilation holes for heat dissipation are installed in the motor casing. Therefore, it is necessary to secure a heat dissipation space for circulating the air around the land pump to forcibly dissipate the heat of the motor unit, and thus a larger installation space is required and the space is effectively used. Can't do it.

[0006] In recent years, it has been proposed that the water supply units are compactly arranged in a plane and housed in the lower part of the water receiving tank. However, since the lower part of the water receiving tank is narrow, maintenance and inspection of the water supply unit are difficult to perform.

The present invention has been made in order to solve the above-mentioned inconvenience, and requires a small installation space, and at least the maintenance and inspection of the control device can be easily performed , and the control
It is intended to provide a water supply unit storage box capable of cooling heat generating parts of the apparatus with water in a water receiving tank .

In the water supply unit storage box according to the present invention, at least a part of the side wall of the water receiving tank is made of a good heat conductor, and a part of the side wall or a part including the side wall is used as a back panel. At least the control device is housed, and the heat generating component of the control device is attached to a part of the side wall either directly or by contact via a pedestal made of a good heat conductor, and cooled by water in the water tank. It is something. In addition, the water supply unit storage box is formed by providing an opening on the side wall of the water receiving tank, water-tightly attaching a side plate made of a good thermal conductor to this opening, and using part of the side wall including the side plate as a back panel. are, together with the housing at least the control device, the heat generating components of the control device, mounted in contact via a pedestal configured directly or thermally conductive to the side plate, a shall be cooled with water in the water tank.

6A is a sluice valve whose one end is connected to the other end of the water inlet pipe 5A, 6B is a sluice valve whose one end is connected to the other end of the water inlet pipe 5B, and 7A is a land pump whose one end is connected to the inlet of the sluice valve 6A. , 7B are land pumps whose one end is connected to the inlet of the sluice valve 6B. 8A is a gate valve whose one end is connected to the outlet of the land pump 7A, 8B is a gate valve whose one end is connected to the outlet of the land pump 7B, 9A is a check valve whose one end is connected to the other end of the gate valve 8A, 9B Indicates a check valve having one end connected to the other end of the gate valve 8B. Reference numeral 10 denotes a water outlet pipe, one end of which is connected to the check valves 9A and 9B. The rectangular panel 1a of this embodiment is made of a good thermal conductor.

[0021]

[0022] Then, the control unit 15 is composed of a run command control section 15a and the inverter 15b. Is the <br/> et al, rectangular-shaped panel 1a is the front upper panel 16A shown in FIGS. 1 and 2, the closure plate 16B, the front lower panel 16
A water supply unit storage box 16 is configured with C.
Further, regarding the land pumps 7A and 7B, the applicant of the present invention applies to Japanese Patent Application No.
It is a rod-shaped structure proposed in Japanese Patent Application No. 47104 and Japanese Patent Application No. 5-47105, in which a liquid to be handled is circulated around the motor unit to cool the motor unit.

The operation of the water supply unit shown in FIG. 3 is as shown in FIG.
Since the operation is the same as the operation of the water supply unit of, the description of the operation will be omitted. However, since the land pumps 7A and 7B are water-cooled and housed in the water supply unit storage box 16 that is in a substantially sealed state, even if the land pumps 7A and 7B operate and an operation sound is generated, the operation sound is generated outside. Therefore, it is possible to obtain a soundproof effect and a dustproof effect for the land pumps 7A and 7B.

Since the land pumps 7A and 7B are covered with the water supply unit storage box 16 in a substantially hermetically sealed condition, they are not directly exposed to the outside air, so that the land pumps 7A and 7B can be protected against the cold. . Furthermore, since the inverter 15b can be cooled without attaching a cooling fin or a cooling fan to the heat generating portion of the inverter 15b, the cost and size of the inverter 15b can be reduced.

In the above embodiment, one square panel 1a is used as the back panel 16D, but a plurality of square panels 1a are used as the back panel 16D.
A part for accommodating the onshore pumps 7A and 7B and the control device 15
It may be divided by a partition wall into a portion for housing. With this configuration, it is possible to obtain a moistureproof effect on the control device 15.

Further, the water supply unit storage box 16 shields the operating sounds of the land pumps 7A and 7B from leaking to the outside, but by providing a soundproof material on the entire inner surface of the water supply unit storage box 16, it is compact. More effective soundproofing can be easily applied.
