Description

Technical Field

[0001] This utility model belongs to the technical field of inverter chambers in photovoltaic power plants, and specifically relates to a cooling system for inverter chambers in photovoltaic power plants. Background Technology

[0002] A photovoltaic (PV) power plant inverter room is typically a room or space dedicated to the installation and operation of PV inverters. Inverters are a key component of PV power generation systems, used to convert the direct current (DC) generated by solar panels into alternating current (AC) for use in the power grid.

[0003] A utility model patent with patent authorization announcement number CN213174964U discloses a pre-assembled substation for a large photovoltaic power station, including a building body. Inside the building body, a photovoltaic inverter, a transformer, an inverter room, and a transformer room are installed. Multiple support rods are fixed to the upper end of the building body, and a water-blocking eaves are fixed to the upper end of the support rods. Two fixing rings are fixed to the upper end of the building body, and heat dissipation mesh is fixed to each of the two fixing rings. Mounting covers are installed on the inner wall of the building body at the positions corresponding to the two fixing rings. Two symmetrical support rods are fixed inside each mounting cover. A motor is fixed to the two support rods inside the mounting cover. A fan is installed on the output shaft of the motor near the fixing rings.

[0004] However, the existing photovoltaic power plant inverter room cooling system also has certain shortcomings. The existing photovoltaic power plant inverter room cooling system mostly uses a single fan to dissipate heat from the electrical components inside the photovoltaic power plant inverter room. Due to the influence of the high temperature environment, the heat dissipation effect is not good, and the electrical components are also easily contaminated by dust, leaves and other impurities in the air. Summary of the Invention

[0005] The purpose of this utility model is to provide a cooling system for the inverter chamber of a photovoltaic power station, which solves the problem that existing photovoltaic power station inverter chamber cooling systems often simply use a single fan to dissipate heat from the electrical components inside the inverter chamber. Due to the influence of the high temperature environment, the heat dissipation effect is not good, and the electrical components are also easily contaminated by dust, leaves and other impurities in the air.

[0006] To achieve the above objectives, this utility model provides a photovoltaic power station inverter chamber cooling system, including a photovoltaic power station inverter chamber body. A door is provided on the front of the photovoltaic power station inverter chamber body, and a window is provided on the front of the photovoltaic power station inverter chamber body and to the left of the door. An installation cylinder is slidably connected to the inner wall of the photovoltaic power station inverter chamber body, and a guide plate is fixedly connected to the inner side wall of the photovoltaic power station inverter chamber body. A plug rod is slidably sleeved on the outer side of the guide plate, and the plug rod is slidably connected to the installation cylinder. An end piece is fixedly connected to the end face of the plug rod away from the installation cylinder, and a heat dissipation mechanism is provided inside the installation cylinder.

[0007] The principle of this utility model is as follows: by pulling the end piece to move away from the mounting cylinder, the insertion rod moves along the surface of the guide piece. Once the spring deforms, it pushes the mounting cylinder into the inverter chamber of the photovoltaic power station. Then, the end piece is released so that the spring returns to its original deformation, thereby pulling the insertion rod into the mounting cylinder and limiting the mounting cylinder, which facilitates quick installation and use by operators.

[0008] The four exhaust fans provide rapid heat dissipation for the electrical components inside the inverter compartment of the photovoltaic power station. The filter removes dust, leaves, and other impurities from the air, preventing them from affecting the components. Pulling the pull ring away from the exhaust fans moves the moving ring, causing it to disengage from the contact block. The spring deforms under the action of the fixing plate. Releasing the pull ring restores the spring's deformation, pushing the moving ring to contact the filter with the contact block, causing the filter to vibrate and clean impurities, ensuring effective airflow.

[0009] The beneficial effects of this utility model are as follows: This solution pushes the installation cylinder into the inverter chamber of the photovoltaic power station. With the help of the plug rod, spring one and other structures, the installation cylinder can be plugged in, making the installation cylinder stable and facilitating quick installation and use by operators. The four exhaust fans can enhance the air circulation rate inside the inverter chamber of the photovoltaic power station, enhance heat dissipation capacity, and achieve a good cooling effect. With the help of the filter screen, dust, leaves and other impurities in the air can be filtered out to avoid affecting the electrical components inside the inverter chamber of the photovoltaic power station. With the help of the pull ring, spring two, contact block and other structures, the filter screen can vibrate to clean the attached impurities.

[0010] Furthermore, four mounting cylinders are provided, which are evenly distributed on the inverter chamber body of the photovoltaic power station. The mounting cylinders can be used for the subsequent installation of components such as exhaust fans.

[0011] Furthermore, a spring is welded to the end face of the end piece near the mounting cylinder, and the other end of the spring is welded to the guide piece. The end piece can be connected and used by means of the spring.

[0012] Furthermore, the heat dissipation mechanism includes an exhaust fan, which is installed on the inner wall of the mounting cylinder. A movable ring is slidably connected to the inner wall of the mounting cylinder, and a filter screen is fixedly connected to the inner wall of the movable ring. A contact block is fixedly connected to the inner wall of the mounting cylinder, and the contact block contacts the filter screen and the movable ring. An end rod is fixedly connected to the end face of the filter screen away from the exhaust fan. A fixing plate is fixedly connected to the inner wall of the mounting cylinder, and a second spring is welded to the end face of the fixing plate near the movable ring. The other end of the second spring is welded to the movable ring. By setting up the exhaust fan, the electrical components inside the inverter chamber of the photovoltaic power station can be quickly cooled. The filter screen helps to prevent the intrusion of impurities. In conjunction with the second spring and the contact block, the filter screen can vibrate to clean impurities.

[0013] Furthermore, multiple contact blocks are provided, and the multiple contact blocks are symmetrically distributed on the mounting cylinder. By setting the contact blocks, the filter screen can be used for contact limiting.

[0014] Furthermore, a pull ring is fixedly connected to the other end of the end rod. The pull ring is made of rubber, which facilitates the movement of the filter screen by pulling it, and the rubber material has good durability.

[0015] Furthermore, multiple springs are provided, and the multiple springs are symmetrically distributed on the moving ring. The moving ring can be connected and used by means of the springs. Attached Figure Description

The insertion rod 6 is slidably connected to the installation cylinder 4. An end piece 7 is fixedly connected to the end face of the insertion rod 6 away from the installation cylinder 4.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, there are four mounting cylinders 4, which are evenly distributed on the inverter chamber body 1 of the photovoltaic power station. The mounting cylinders 4 can be used for the installation of components such as the exhaust fan 91. A spring 8 is welded to the end face of the end piece 7 near the mounting cylinder 4. The other end of the spring 8 is welded to the guide plate 5. The spring 8 can be used to connect the end piece 7.

[0024] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the mounting cylinder 4 has a heat dissipation mechanism 9 inside, which includes an exhaust fan 91. The exhaust fan 91 is installed on the inner wall of the mounting cylinder 4. A moving ring 92 is slidably connected to the inner wall of the mounting cylinder 4. A filter screen 93 is fixedly connected to the inner wall of the moving ring 92.

The filter 93 can prevent the intrusion of impurities. With the setting of the spring 98, contact block 94 and other structures, the filter 93 can be vibrated to clean the impurities.

[0025] like Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, multiple contact blocks 94 are provided, and the multiple contact blocks 94 are symmetrically distributed on the mounting cylinder 4. The contact blocks 94 can be used to limit the contact of the filter screen 93. The other end of the end rod 95 is fixedly connected to a pull ring 96. The pull ring 96 is made of rubber.

Multiple springs 98 are provided, and the multiple springs 98 are symmetrically distributed on the moving ring 92. The moving ring 92 can be connected and used through the springs 98.

[0026] The specific implementation process of this utility model is as follows: by pulling the end piece 7 to move away from the mounting cylinder 4, the insertion rod 6 moves along the surface of the guide piece 5, the spring 8 deforms, and then pushes the mounting cylinder 4 into the inverter chamber body 1 of the photovoltaic power station, and releases the end piece 7 so that the spring 8 returns to its original deformation, so as to pull the insertion rod 6 into the mounting cylinder 4, thereby limiting the mounting cylinder 4 and facilitating the quick installation and use by the operators;

[0027] The four exhaust fans 91 provide rapid heat dissipation for the electrical components inside the inverter chamber 1 of the photovoltaic power station.

Pulling the pull ring 96 away from the exhaust fans 91 moves the moving ring 92, causing it and the filter 93 to disengage from the contact block 94. Under the action of the fixing plate 97, the second spring 98 deforms. Releasing the pull ring 96 restores the spring 98's deformation, pushing the moving ring 92 to contact the filter 93 with the contact block 94, causing the filter 93 to vibrate and clean impurities, ensuring effective airflow.

[0028] This solution involves pushing the mounting cylinder 4 into the inverter chamber body 1 of the photovoltaic power station.
