Photovoltaic power generation facilities are built near user sites, and excess power is transmitted to the public power grid through a grid connection system, or power is supplemented from the grid when insufficient, thereby achieving efficient utilization and balance regulation of energy. The new type of distributed photovoltaic power generation metering box is a key device in the distributed photovoltaic power generation system, and it realizes the metering, distribution, protection, and monitoring of electrical energy through electrical equipment such as electric energy meters, circuit breakers, and contactors installed inside.

[0003] However, in order to prevent excessive dust particles from entering the interior of the box body, a dust-proof filter plate is often installed at the air inlet. At present, most of the existing new type of distributed photovoltaic power generation metering boxes on the market are not convenient for staff to clean or replace the dust-proof filter plate, and most of the existing new type of distributed photovoltaic power generation metering boxes on the market are not convenient for staff to remove them from the exterior wall of the building to replace or repair the metering box with damaged outer walls, increasing the operation difficulty of the staff.

[0004] Therefore, technical personnel in this field have provided a new type of distributed photovoltaic power generation metering box to solve the problems raised in the above background technique. Content of the Utility Model

[0005] The purpose of the content of the utility model is to solve the disadvantages existing in the prior art, and provide a new type of distributed photovoltaic power generation metering box. Through the action of the reset spring on the sliding rod, the convex block can be inserted into the box body, and by using the rotating block to pull out and rotate the convex block, the clamping of the limiting plate is released, which is convenient for replacement. And through the sliding connection of the connecting block and the connecting groove, and the clamping connection of the clamping block and the connecting block, it is convenient to disassemble the box body.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A new type of distributed photovoltaic power generation metering box, including a box body and a dust-proof filter plate. A ventilation inlet is opened in the middle of the front outer wall of the box body. A limiting mechanism is arranged inside the box body. The limiting mechanism includes two sliding rods and two limiting plates. Sliding grooves are opened on both sides of the middle of the front end inside the box body. Reset springs are fixedly connected to the inner walls of the front ends of the sliding grooves. Rotating pieces are rotatably connected to the rear ends of the outer walls of the sliding rod bodies. The outer walls of the sliding rod bodies are slidably connected to the limiting plates. The limiting plates are clamped and connected to the dust-proof filter plate. The front ends of the sliding rods all penetrate through the box body and are rotatably connected to rotating blocks;

[0008] The upper and lower ends of the outer wall of the rear end of the rotating block are fixedly connected with bumpers. A fixing mechanism is arranged on the other side of the box body. The fixing mechanism includes a fixing frame and two threaded rods. The upper and lower ends of the outer wall of one side of the fixing frame are fixedly connected with connecting blocks. The upper and lower ends of the outer wall of the front end of the box body are fixedly connected with fixing frames. The upper ends of the outer wall of the threaded rod body are threadedly connected with clamping blocks. The other sides of the clamping blocks are clamped and connected with the connecting blocks;

[0009] Through the above technical solution, the bumper on the rotating block is inserted into the box body under the action of the return spring, so that the limiting plate keeps the clamping state of the dust-proof filter plate, and the dust-proof filter plate is fixed. By pulling out and rotating the bumper with the rotating block, the clamping state of the limiting plate on the dust-proof filter plate is released, which is convenient for cleaning or replacing the dust-proof filter plate.

[0010] Furthermore, an installation frame is fixedly connected to the inner wall of the other side of the box body. Connecting grooves are opened at the upper and lower ends of the outer wall of the other side of the box body. The connecting grooves are slidably connected with the connecting blocks. The lower ends of the outer wall of the threaded rod body are fixedly connected with dial wheels;

[0011] Through the above technical solution, the connecting blocks fixedly connected to the fixing frame are slidably connected with the connecting grooves opened on the box body. With the clamping connection between the clamping blocks and the connecting blocks, the box body is fixed. By using the dial wheel to drive the threaded rod and the clamping block to release the clamping state of the connecting block, it is convenient for the staff to remove the metering box from the building exterior wall.

[0012] Furthermore, hinges are fixedly connected to the upper and lower front ends of the outer wall of one side of the box body. The rear ends of the hinges are fixedly connected with a box door;

[0013] Through the above technical solution, the two hinges fixedly connected to the box door are hinged to the box body, which allows the staff to freely open and close. When the box door is closed, it can provide protection for the internal electrical components in cooperation with the box body. When the box door is opened, it is convenient for the staff to repair or operate the electrical components inside the box body.

[0014] Furthermore, an air outlet is opened in the middle of the outer wall of the rear end of the box body. A cooling fan is arranged inside the air outlet;

[0015] Through the above technical solution, through the air inlet and air outlet opened on the box body, the relatively cold external air can enter the inside of the box body. With the cooling fan arranged in the air outlet, it can accelerate the flow of internal and external air, take out the heat generated by the internal electrical equipment, and enhance the heat dissipation capacity.

[0016] Furthermore, the rear ends of the return springs are fixedly connected with rotating pieces. The rotating pieces slide inside the sliding grooves;

[0017] Through the above technical solution, the reset spring acts on the rotating piece, and the rotating piece is rotatably connected to the sliding rod, so that the elastic force can make the sliding rod drive the rotating block to adhere to the surface of the box body. Also, by rotating the rotating block, the sliding rod can be driven to rotate, and in cooperation with the sliding connection between the sliding rod and the limiting plate with a cross-shaped groove, the limiting plate can be made to rotate following the sliding rod.

[0018] Further, the inner walls of the air inlet are all slidably connected to the dust-proof filter plate, and the convex blocks are all slidably connected to the box body;

[0019] Through the above technical solution, the elastic force of the reset spring makes the sliding rod drive the rotating block to adhere to the surface of the box body, so that the convex block fixedly connected to the rotating block can be inserted into the corresponding groove of the box body. Then, when the rotating block is pulled up and rotated, the limiting plate rotates following it to release the clamping connection of the dust-proof filter plate, and the dust-proof filter plate can be taken out from the air inlet. When the limiting plate is in the clamping state of the dust-proof filter plate, by inserting the convex block on the box body, the rotation of the rotating block can be prevented, and the self-rotation of the limiting plate can be avoided.

[0020] Further, the top and bottom surfaces of the inner part of the fixed frame are both rotatably connected to the threaded rod, and the clamping blocks are all slidable inside the fixed frame;

[0021] Through the above technical solution, since the dial wheel is fixedly connected to the threaded rod, the staff can use the dial wheel to drive the threaded rod to rotate inside the fixed frame. And by the threaded connection between the threaded rod and the clamping block, the rotating threaded rod can drive the clamping block to move up and down along the inside of the fixed frame, changing the clamping state of the connecting block.

Detailed implementation manners

[0033] Next, the technical solutions in the specific implementation manners of the present utility model will be clearly and completely described in conjunction with the drawings in the specific implementation manners of the present utility model. Obviously, the described specific implementation manners are only a part of the specific implementation manners of the present utility model, rather than all of the specific implementation manners. Based on the specific implementation manners of the present utility model, all other specific implementation manners obtained by those of ordinary skill in the art without creative efforts shall fall within the scope of protection of the present utility model.

[0034] Refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6, the present utility model provides a specific implementation: a new type of distributed photovoltaic power generation metering box, including a box body 1 and a dust-proof filter plate 10. A ventilation inlet 4 is provided in the middle of the front outer wall of the box body 1. A limiting mechanism 7 is arranged inside the box body 1. The limiting mechanism 7 includes two sliding rods 704 and two limiting plates 706. Slide grooves 701 are provided on both sides of the middle of the front end inside the box body 1. Return springs 702 are fixedly connected to the inner walls of the front ends of the slide grooves 701. Rotating pieces 703 are rotatably connected to the outer walls of the rear ends of the rod bodies of the sliding rods 704. The outer walls of the rod bodies of the sliding rods 704 are slidably connected to the limiting plates 706. The limiting plates 706 are snap-connected to the dust-proof filter plate 10. The front ends of the sliding rods 704 penetrate through the box body 1 and are rotatably connected to rotating blocks 705. Upper and lower ends of the outer wall of the rear end of the rotating block 705 are fixedly connected with convex blocks 707.

[0035] Upper and lower front ends of one side outer wall of the box body 1 are fixedly connected with hinges 2. Rear ends of the hinges 2 are fixedly connected with a box door 3. The box door 3 is hinged to the box body 1 through the two hinges 2 fixedly connected thereto, enabling the staff to freely open and close. When the box door 3 is closed, it can cooperate with the box body 1 to provide protection for the internal electrical components. When the box door 3 is opened, it is convenient for the staff to repair or operate the electrical components inside the box body 1. An air outlet 5 is provided in the middle of the rear outer wall of the box body 1. A cooling fan 6 is arranged inside the air outlet 5. Through the ventilation inlet 4 and the air outlet 5 provided on the box body 1, cooler external air can enter the inside of the box body 1. Coupled with the cooling fan 6 arranged inside the air outlet 5, it can accelerate the flow of internal and external air, take out the heat generated by the internal electrical equipment, and enhance the heat dissipation capacity. Rear ends of the return springs 702 are fixedly connected to the rotating pieces 703. The rotating pieces 703 slide inside the slide grooves 701. Due to the action of the return spring 702 on the rotating piece 703, and the rotating piece 703 is rotatably connected to the sliding rod 704, the elastic force enables the sliding rod 704 to drive the rotating block 705 to stick to the surface of the box body 1. Also, by rotating the rotating block 705, the sliding rod 704 can be driven to rotate. Cooperating with the sliding connection between the sliding rod 704 and the limiting plate 706 with a cross-shaped groove, the limiting plate 706 rotates following the sliding rod 704. Inner walls of the ventilation inlet 4 are slidably connected to the dust-proof filter plate 10. The convex blocks 707 are slidably connected to the box body 1. Due to the elastic force of the return spring 702, the sliding rod 704 drives the rotating block 705 to stick to the surface of the box body 1, so that the convex blocks 707 fixedly connected to the rotating block 705 can be inserted into the corresponding grooves of the box body 1. Thus, when the rotating block 705 is pulled up and rotated, the limiting plate 706 rotates to release the snap connection to the dust-proof filter plate 10, and the dust-proof filter plate 10 can be taken out from the ventilation inlet 4. When the limiting plate 706 is in the snap connection state with the dust-proof filter plate 10, by inserting the convex block 707 into the box body 1, the rotation of the rotating block 705 can be prevented, avoiding the self-rotation of the limiting plate 706.

[0036] Refer toFigure 1 、 Figure 2 and Figure 5 , a fixing mechanism 9 is provided on the other side of the box body 1, and the fixing mechanism 9 includes a fixing frame 901 and two threaded rods 905. The upper end and the lower end of the outer wall of one side of the fixing frame 901 are fixedly connected to the connecting block 902, and the upper end and the lower end of the outer wall of the front end of the box body 1 are fixedly connected to the fixing frame 904, the upper end of the outer wall of the threaded rod 905 is threadedly connected to the clamping block 907, and the other side of the clamping block 907 is clamped and connected with the connecting block 902. The inner wall of the other side of the box body 1 is fixedly connected to the mounting frame 8, and the upper end and the lower end of the outer wall of the other side of the box body 1 are provided with a connecting groove 903, and the connecting groove 903 is slidably connected to the connecting block 902, and the lower end of the outer wall of the threaded rod 905 is fixedly connected to the dial wheel 906.

[0037] The connecting block 902 fixedly connected on the fixing frame 901 is slidably connected with the connecting groove 903 opened on the box body 1, and the clamping block 907 is clamped and connected with the connecting block 902, so that the box body 1 is fixed, and the threaded rod 905 is driven by the dial wheel 906 to drive the clamping block 907 to release the clamping state of the connecting block 902, thereby facilitating the staff to remove the metering box from the outer wall of the building. The top and bottom surfaces of the interior of the fixed frame 904 are both rotatably connected to the threaded rod 905, and the clamping block 907 slides inside the fixed frame 904, and is fixedly connected to the threaded rod 905 by the dial wheel 906, so that the staff can use the dial wheel 906 to drive the threaded rod 905 to rotate in the fixed frame 904, and use the threaded connection between the threaded rod 905 and the clamping block 907 to make the rotating threaded rod 905 drive the clamping block 907 to move up and down along the interior of the fixed frame 904, changing the clamping state of the connecting block 902.

[0038] Working principle: When using this new distributed photovoltaic power generation metering box, the staff first fixes the fixing frame 901 in the required position with multiple bolts and nuts, then uses the connecting groove 903 to slide with the connecting block 902, and drives the threaded rod 905 to engage the clamping block 907 with the connecting block 902 by toggling the dial wheel 906 to fix the box body 1. Then, the staff uses the mounting frame 8 inside the box body 1 to fix the required electrical equipment, such as electricity meters, circuit breakers, and contactors, in the box body 1 with bolts and nuts. After closing the box door 3, the cooling fan 6 can be used in conjunction with the air inlet 4 and the air outlet 5 to accelerate the air flow inside and outside for heat dissipation.

[0039] Secondly, the staff can pull up and rotate the rotating block 705, so that the convex block 707 slides out of the box body 1, and the sliding rod 704 drives the limiting plate 706 to release the clamping state of the dust-proof filter plate 10, facilitating the replacement or cleaning of the dust-proof filter plate 10. Then, the dust-proof filter plate 10 is placed into the air inlet 4, the rotating block 705 is pulled up and rotated, so that the limiting plate 706 resumes the clamping state of the dust-proof filter plate 10, and under the action of the return spring 702, the rotating block 705 adheres to the box body 1, and the convex block 707 is inserted into the box body 1 to prevent the limiting plate 706 from rotating, thereby fixing the dust-proof filter plate 10;

[0040] Finally, after the internal electrical equipment is removed by the staff, the dial 906 is used to drive the rotation of the threaded rod 905, so that the clamping block 907 moves downward to release the clamping state of the connecting block 902. Then, the staff can slide out the damaged box body 1 along the connecting block 902 and replace it with a new one. Then, the dial 906 is used to drive the threaded rod 905 to make the clamping block 907 resume the clamping state of the connecting block 902, thereby fixing the box body 1.
