Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) The present invention relates to a simple power supply storage device that supplies necessary power to a load.

(Conventional Technique v#) As a simple power supply storage device, there is one in which a storage battery and a power converter are stored in a power supply box. This power supply storage device is used, for example, in a small solar power generation system, and stores the electricity generated by solar cells in a storage battery, and converts the electricity from this storage battery into electricity according to the load using a power converter. There is.

When storing the storage battery and the power converter in the power supply box in this way, the storage battery is placed at the bottom of the power supply box, and the power converter is placed above it. By the way, in order to facilitate maintenance and inspection of the storage battery, or to provide a means to remove gas to prevent electrolyte gas from filling the power supply box, there is a relatively large gap between the storage battery and the power converter. A large space is secured.

(Problems to be Solved by the Invention) As described above, since a relatively wide space is secured between the storage battery and the power converter, the power supply storage device is large-sized. Furthermore, the structure is complicated because the power storage unit must have a shielding structure or a ventilation structure so that gas from the electrolyte does not have an adverse effect on the power converter located above.

The present invention has been made in view of the above circumstances, and an object of the present invention is to provide a power supply storage device that is small in size and has a simple structure.

(Means for Solving the Problems) In order to solve the above problems, the present invention provides a power supply storage device that stores a storage battery and a power converter in a power supply box and is capable of supplying power according to the load. The power supply box is characterized in that the storage battery is placed on the side of the power converter via a partition wall, and an opening/closing means is provided on the upper surface of the power supply box facing the storage battery.

(Function) In this invention, the storage battery is placed on the side of the power converter,
Maintenance and inspection work on the storage battery is performed by opening and closing the opening/closing means provided at the top.

Therefore, there is no need to secure a space in the power supply box for maintenance and inspection of the storage battery. In addition, gas generated from the electrolyte can be protected by a simple structure in which the storage battery and the power converter are sealed off with a partition wall, without the need for special means.

(Example) Hereinafter, an example of the present invention will be described in detail based on the accompanying drawings.

FIG. 1 shows a schematic diagram of a small-sized solar power generation system to which the present invention is applied.

1 is a solar cell, 2 is a power supply storage device, and 3 is a load. The solar cell 1 converts sunlight energy into electrical energy and uses it as a power source.

This power is stored in the power supply storage device 2 and supplied to the load 3 as needed. The loads 3 include a fluorescent lamp 4, an electric light 5, a television 6, a radio 7, a pump motor 8, and the like.

The power supply storage device 2 is constructed as shown in FIGS. 2 and 3.

A power converter 10 is arranged inside the power supply box 9 of the power supply storage device 12, and a storage battery 12 is arranged with a partition wall 11 separating the power converter 10.

A drain guide 13 is provided at the bottom of the storage battery 12, and a drain receiver 14 is arranged below the drain guide 13. The drain guide 13 is inclined at a predetermined angle, and a large number of drain discharge parts 15 are provided in series at the center of the bottom thereof.

When checking the specific gravity of the electrolytic solution stored in the storage battery 12 or injecting make-up water, if the electrolytic solution leaks, it is caught by the drain guide 13 and stored in the drain receiver 14 from the drain discharge part 15. This drain receiver 14 can be attached from the front of the power supply box 9.

The power converter 10 is disposed close to the side of the storage battery 12 and the partition wall 11, and the top surface of the power supply box 9 is formed low enough to be close to the top of the storage battery 12.
This reduces the height of the power supply box 9.

A door 16, which serves as an opening/closing means, is provided on the top surface of the power supply box 9, and by opening this r316 upward, maintenance and inspection of the storage battery 12, as well as confirmation of the specific gravity of the electrolyte, etc., can be carried out. There is.

Moreover, 7317.18 is provided on the front side of the power supply box 9, so that the storage battery 12 and the power converter 10 can be taken in and out independently. Furthermore, openings 19 and 20 are formed on the top and side surfaces of the power supply box 9 to vent corrosive gas.

Next, the operation of this embodiment will be explained.

Open the right door 18 provided on the front of the power supply storage device 2,
A power converter 10 is housed in one of the rooms separated by a partition wall 11. Then, open the left side 317 and place the storage battery 12 in the E section of the drain guide 13.

When this power supply storage device 2 is used, corrosive gas and mist generated from the storage battery 12 are removed from the openings 19 on the side and top surfaces.
Since the air is discharged to the outside from 20, there is no need to provide ventilation means such as a fan inside, which is advantageous in manufacturing.

Further, a power converter 10 is connected to a storage battery 1 with a partition wall 11 in between.
Since the power converter 1 is located on the side of the power converter 1, it is less likely to be adversely affected by electrolytes and corrosive gases.
There is no need for a special coating or treatment to prevent corrosion on the 0, reducing costs.

Maintenance and inspection of the storage battery 12 can be easily performed from above by opening the door 16 provided on the top surface. Further, even if a droplet occurs when checking the specificity of the electrolyte in the storage battery 12 or replenishing water, there is no risk of the electrolyte adhering to the power converter 10 and malfunctioning because it is blocked by the partition wall 11.

Further, when replenishing the storage battery 12 with this water, overflowing electrolyte is collected via the drain guide 13 and guided from the drain discharge part 15 to the drain receiver 14.

Since this drain receiver 14 can be pulled out from the front, waste liquid can be easily discharged to the outside of the power supply box 9.

In the above embodiment, the J$17 through which the storage battery 12 can be taken in and taken out is provided on the front surface, but it may be provided on the rear surface or side surface. Further, the opening/closing means provided on the upper surface of the power supply box 9 may be a sliding door. Furthermore, the power conversion unit IO is not limited to one front surface of the power supply box 9, and may be detachable from any one of the side surface, rear surface, and top surface.

(Effects of the Invention) As described in the above, this invention places the storage battery on the side of the power converter and provides the opening/closing means on the top surface of the power supply box facing the storage battery. The inspection work is done from above, making the work easy. Also,
There is no need to secure a work space inside the power supply box as in the past, and the device becomes smaller. Further, the gas generated from the electrolyte can be discharged to the outside of the power supply box without adversely affecting the power converter even with a simple structure that does not require any special means.
