Description

Technical Field

[0002] In photovoltaic systems, switch cabinets specifically refer to those devices responsible for distributing electrical energy to various parts, controlling the operation of the system, and monitoring and protecting the system. When these functions are specifically for smart photovoltaic street lights, they are combined into switch cabinets for smart photovoltaic street light control. By combining advanced microelectronics technology, sensor technology and communication technology, remote monitoring, intelligent dimming, fault self-detection and other functions can be achieved.

[0003] The installation position of the mounting plate of the electrical components is fixed and cannot be adjusted, which means that when workers inspect, maintain and replace the electrical components installed on the side of the mounting plate, they need to put their hands or bodies into the interior of the switch cabinet to install, dismantle, repair and replace the electrical components. Since the internal space of the switch cabinet is small, it is very inconvenient for workers to install, dismantle, repair and replace the electrical components. The steps are cumbersome, the work efficiency is low, and the practicality is poor.

[0004] Based on the above technical problems, the prior art also provides some solutions. For example, the Chinese patent with the authorization announcement number CN114566892A discloses a smart street light control switch cabinet. The safety door can adjust and position the use position of the electrical installation board through the functional drive component. When the electrical components need to be replaced or repaired, the safety door can be pushed open to realize the function of the safety door driving the electrical installation board to move outward through the functional drive component. The electrical installation board is pushed outward to increase the operating space for the staff to operate the electrical components installed on the electrical installation board. It is convenient and flexible to use, and solves the problem that the installation position of the control switch cabinet installation board is fixed and cannot be adjusted. Due to the small internal space of the switch cabinet, it is very inconvenient for the staff to install, disassemble, repair and replace the electrical components, the steps are cumbersome, and the work efficiency is low.

[0047] In this embodiment, a cooling mechanism 6 is provided on the inner side of the side protection box 301, and the cooling mechanism 6 includes a liquid storage tank 601, a top connecting pipe 602 and a liquid inlet pump 603.

[0048] It should be noted that by starting the liquid outlet pump 606, the cooling liquid in the cooling plate 604 will flow back to the liquid storage tank 601 along the bottom connecting pipe 605 through the liquid outlet pump 606. By driving the liquid inlet pump 603 and the liquid outlet pump 606, the cooling liquid can be driven through the connection between the top connecting pipe 602 and the bottom connecting pipe 605 to circulate in the liquid storage tank 601 and the cooling plate 604, so that the cooling plate 604 in the opposite side protection box 301 can be continuously cooled using the cooling liquid.

[0049] In this embodiment, there are two liquid storage tanks 601 , and both sides of the two liquid storage tanks 601 are fixedly connected with heat sinks 607 , and there are multiple heat sinks 607 .

[0050] It should be noted that the coolant in the liquid storage tank 601 will continuously dissipate heat through the multiple heat sinks 607. The multiple heat sinks 607 will increase the heat dissipation area of ​​the liquid storage tank 601, and can maintain the heat dissipation when the coolant circulates in the liquid storage tank 601.

[0051] In this embodiment, a heat exchange fin 608 is fixedly connected to one side of the cooling plate 604 . There are multiple heat exchange fins 608 , and the multiple heat exchange fins 608 are arranged in parallel along the inner side of the cooling plate 604 .

[0052] It should be noted that after the transmission fan 307 rotates to draw external air into the side protection box 301, the gas will pass through multiple heat exchange plates 608. The air entering the side protection box 301 will contact the cold surface of the heat exchange plate 608 and heat exchange will occur. The air will lose heat and be cooled when contacting the heat exchange plate 608. At this time, the cooled gas will be blown into the control cabinet 1 and cool the intelligent circuit control cabinet in the control cabinet 1, thereby improving the cooling effect, improving the stability of continuous use in high temperature environment, and extending the service life of the control cabinet 1.

[0053] In this embodiment, two sides of the side protection box 301 are provided with communication holes 609 , the number of the communication holes 609 is four, and the inner sides of the four communication holes 609 are respectively arranged on the surface of the top communication tube 602 and the bottom communication tube 605 .

[0054] It should be noted that, through the opening of the connecting hole 609, the coolant in the liquid storage tank 601 can be transferred to the cooling plate 604 via the top connecting tube 602, and the liquid in the cooling plate 604 can be transferred to the liquid storage tank 601 via the bottom connecting tube 605. By opening the liquid storage tank 601, the top connecting tube 602 and the bottom connecting tube 605 can be passed through the inside and outside of the side protection box 301.

[0055] The specific working steps of a switch cabinet for intelligent photovoltaic street light control are as follows:

[0056] First, the motor body 305 is started, and the bottom transmission rod 306 is driven to rotate by the motor body 305. The motor body 305 can be stably supported on the top of the bottom connection frame 303 through the connection of the top support frame 304. During the rotation of the bottom transmission rod 306, the transmission fan 307 is synchronously driven to rotate. The rotating transmission fan 307 generates wind along the inner side of the bottom connection frame 303, and blows the air outside the side protection box 301 into the side protection box 301 along the top connection frame 302, which can improve the air circulation performance in the control cabinet 1 and reduce the influence of water vapor on the circuit equipment in the control cabinet 1 in a humid environment.

[0057] At the same time, when the gas enters the side protection box 301 along the top connecting frame 302, the air will be blown into the inner side of the top protection cylinder 401 along the top connecting plate 402 during the rotation of the transmission fan 307. Through the connection of the top filter 403 inside the top connecting plate 402, dust particles in the air can be filtered and blocked, and the dust particles are blocked on the surface of the top filter 403. After the gas is blown into the side protection box 301, it will be discharged along the inner side of the bottom connecting frame 404 to maintain the air circulation in the control cabinet 1, and the bottom filter 406 arranged on the inner side of the bottom connecting frame 404 is used to filter and block dust particles. The bottom filter 406 is fixed to the inner side of the bottom connecting frame 404 through the bottom protection frame 405, and the sundries in the side protection box 301 are stored through the storage tray 407 fixed on the top of the bottom protection frame 405, and the sundries in the side protection box 301 fall into the bottom filter 406 along the storage tray 407 for centralized storage. By using the filtering mechanism 4, while maintaining the air circulation in the side protection box 301 and the control cabinet 1, the influence of external dust particles entering the control cabinet 1 on the circuit equipment is reduced, thereby improving the protection of the intelligent photovoltaic circuit in the control cabinet 1;

[0058] At the same time, when the motor body 305 drives the bottom transmission rod 306 to rotate, the rotating bottom transmission rod 306 will be movably sleeved on the bottom of the top fixing frame 501 through the bearing ring 502, and the bearing ring 502 will be limited and supported by the top fixing frame 501 to maintain the stability of the bottom transmission rod 306 during rotation. In the process of rotation, the bottom transmission rod 306 will synchronously drive the top transmission plate 503 to rotate, and the rotating top transmission plate 503 will drive the cleaning brush 504 to rotate. The rotating cleaning brush 504 will rotate and clean along the surface of the top filter 403, and clean the dust particles accumulated on the surface of the top filter 403. After cleaning, the top filter 403 will improve the filtering effect, and at the same time improve the ventilation performance, reducing the influence of dust on ventilation.

[0059] When the transmission fan 307 rotates and ventilates the side protection box 301 and the control cabinet 1, the liquid inlet pump 603 is started, and the cooling liquid in the liquid storage tank 601 flows along the top connecting pipe 602 to the cooling plate 604 through the liquid inlet pump 603. After the cooling liquid continues to flow downward in the cooling plate 604, the liquid outlet pump 606 is started, and the cooling liquid in the cooling plate 604 flows back to the liquid storage tank 601 along the bottom connecting pipe 605 through the liquid outlet pump 606. The cooling liquid can be driven by the connection between the top connecting pipe 602 and the bottom connecting pipe 605 to realize circulation in the liquid storage tank 601 and the cooling plate 604, so that the cooling liquid can be used to continuously cool the cooling plate 604 in the side protection box 301, and the two cooling plates 604 are connected by the heat exchange plate 608. Thereby, the multiple heat exchange fins 608 can be continuously cooled, and the coolant in the liquid storage tank 601 will continuously dissipate heat through the multiple heat sinks 607. The multiple heat sinks 607 will increase the heat dissipation area of ​​the liquid storage tank 601, and the heat dissipation can be maintained when the coolant circulates in the liquid storage tank 601. At this time, after the transmission fan 307 rotates to draw external air into the side protection box 301, the gas will pass through the multiple heat exchange fins 608. The air entering the side protection box 301 will contact the cold surface of the heat exchange fins 608 and heat exchange will occur. The air will lose heat when contacting the heat exchange fins 608, that is, it will be cooled. At this time, the cooled gas will be blown into the control cabinet 1, and cool the intelligent circuit control cabinet in the control cabinet 1, thereby improving the cooling effect, improving the stability of continuous use in a high temperature environment, and extending the service life of the control cabinet 1.
