Description

Technical Field

[0001] The present invention relates to the technical field of electrical protection in power plants, and particularly to an electrical protection device for power plants. Background Art

[0002] In the power industry, electrical protection devices in power plants are key equipment to ensure the stable operation of the power system, and their performance and reliability are crucial. However, during long-term operation, these electrical protection devices face a series of challenges, especially temperature rise and heat dissipation problems. Since a large number of electronic components and circuits are integrated inside the electrical protection devices, they generate a large amount of heat energy during continuous operation, causing the temperature of the devices to gradually increase. The high-temperature environment not only accelerates the aging process of electrical components and reduces their service life, but also increases the risk of electrical accidents such as short circuits and overloads, seriously threatening the safe and stable operation of the power system.

[0003] To solve this problem, the commonly adopted method in the prior art is to install a fan inside the electrical protection device for heat dissipation. The fan accelerates the air flow and takes away the heat inside the power distribution cabinet, thereby achieving the effect of temperature reduction. However, this traditional heat dissipation method has many deficiencies. First of all, the fan is usually fixed at a certain position of the electrical protection device, resulting in limited heat dissipation effect and unable to evenly and effectively reduce the temperature inside the entire electrical protection device. Especially in the case where electrical components are densely arranged or the space is limited, the fan at a fixed position often fails to cover all areas that need heat dissipation.

[0004] Secondly, impurities such as dust and particulate matter in the air are easily adhered to the heat dissipation net. As time goes by, more and more dust accumulates on the heat dissipation net, resulting in poor air circulation and further affecting the heat dissipation effect. The blockage of the heat dissipation net not only exacerbates the problem of temperature rise inside the electrical protection device, but may also cause more serious electrical faults due to poor heat dissipation. Summary of the Invention

[0005] The purpose of the present invention is to provide an electrical protection device for power plants to solve the problems that the heat dissipation effect of the existing electrical protection device is limited, the fan at a fixed position cannot evenly and effectively reduce the temperature inside the entire electrical protection device, and the heat dissipation net is easily blocked by dust, resulting in poor air circulation and exacerbating the problem of temperature rise inside the electrical protection device.

Specific embodiments

[0025] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0026] As Figures 1 to 8 shown, an electrical protection device for a power plant includes a mounting base plate 100. An electrical component body 104 is mounted on the top of the mounting base plate 100. A protective cover 102 that wraps the electrical component body 104 is covered on the top of the mounting base plate 100. Heat dissipation nets 106 are provided on the opposite side walls of the protective cover 102. A heat dissipation mechanism 300 capable of reducing the temperature inside the protective cover 102 and a dust removal mechanism 400 for cleaning the dust on the heat dissipation nets 106 are provided inside the protective cover 102. A clamping mechanism 200 that can facilitate the disassembly and assembly of the protective cover 102 is provided on the outer side wall of the protective cover 102.

[0027] In this embodiment, the heat dissipation mechanism 300 includes a motor 105 fixedly provided at the top of the protective cover 102. The output end of the motor 105 penetrates through the protective cover 102 and extends into the interior of the protective cover 102, and is fixedly sleeved with a main bevel gear 306. A bidirectional lead screw 303 is rotatably provided between the inner side walls of the protective cover 102. A secondary bevel gear 305 meshingly connected to the main bevel gear 306 is fixedly sleeved at the middle position of the rod body of the bidirectional lead screw 303. A guide rod 304 parallel to the bidirectional lead screw 303 is fixedly provided between the inner side walls of the protective cover 102. Two moving boxes 301 are symmetrically provided on the bidirectional lead screw 303 and the guide rod 304. The moving box 301 is threadedly connected to the bidirectional lead screw 303 through a moving sleeve. A main bevel gear 307 is fixedly provided outside the moving sleeve. A secondary bevel gear 308 meshingly connected to the main bevel gear 307 is rotatably provided on the inner bottom wall of the moving box 301. A connecting shaft 309 is fixedly provided at the end of the secondary bevel gear 308. The connecting shaft 309 extends outside the bottom of the moving box 301 and a plurality of fans 302 are circumferentially provided. The moving box 301 is slidably matched with the guide rod 304.

[0028] Start the motor 105 fixedly provided at the top of the protective cover 102. The output end of the motor 105 drives the main bevel gear 306 to rotate. By using the meshing of the main bevel gear 306 and the secondary bevel gear 305, the bidirectional lead screw 303 is driven to rotate. The rotation of the bidirectional lead screw 303 causes the two moving boxes 301 to symmetrically move under the guidance of the guide rod 304. When the moving box 301 moves, it drives the main bevel gear 307 to rotate. Through the meshing of the main bevel gear 307 and the secondary bevel gear 308, the connecting shaft 309 is driven to rotate, and then a plurality of fans 302 are rotated. As the moving box 301 moves, the fans 302 move back and forth inside the protective cover 102, realizing all-round heat dissipation for the electrical component body 104, effectively solving the problem of uneven heat dissipation of the traditional fixed-position fan. Multiple fans work simultaneously, accelerating the air flow inside the protective cover, improving the heat dissipation efficiency, and making the temperature inside the electrical protection device more uniform and stable.

[0029] In this embodiment, the dust removal mechanism 400 includes mounting plates 402 fixedly provided at the four corners of the inner wall of the protective cover 102. A screw rod 405 is rotatably provided between the top of the mounting plate 402 and the top of the protective cover 102, and a limiting rod 401 is fixedly provided. The screw rods 405 and the limiting rods 401 are symmetrically arranged in pairs. A moving plate 403 is provided on the rod bodies of the screw rod 405 and the limiting rod 401 on the same side. One end of the moving plate 403 is threadedly connected to the screw rod 405, and the other end is slidably fitted with the limiting rod 401. A cleaning plate 404 in contact with the heat dissipation net 106 is provided on the side wall of the moving plate 403. A first synchronous pulley 406 is fixedly sleeved on the output end of the motor 105 and on the rod body of one of the screw rods 405. A first synchronous belt 407 is provided between the first synchronous pulleys 406. Second synchronous pulleys 408 are fixedly sleeved on the rod bodies of the screw rod 405 below the first synchronous pulley 406 and on the rod body of the other screw rod 405. A second synchronous belt 409 is provided between the second synchronous pulleys 408.

[0030] While driving the heat dissipation mechanism, the output end of the motor 105 also drives one of the screw rods 405 to rotate through the first synchronous pulley 406 and the first synchronous belt 407. This screw rod 405 drives the other screw rod 405 to rotate synchronously through the second synchronous pulley 408 and the second synchronous belt 409. The rotation of the screw rod 405 causes the moving plate 403 to move up and down under the guidance of the limiting rod 401. When the moving plate 403 moves, the cleaning plate 404 on its side wall also moves accordingly, wiping the heat dissipation net 106 back and forth, removing the dust and particulate matter adhering to the heat dissipation net 106, keeping the heat dissipation net 106 unobstructed, ensuring the smooth flow of air, enabling the heat dissipation effect to be continuously and efficiently exerted, and reducing the risk of electrical failures caused by poor heat dissipation.

[0031] In this embodiment, the clamping mechanism 200 includes clamping bases 202 fixedly provided at the top of the mounting base plate 100 and symmetrically arranged along the central axis of the protective cover 102. A moving groove 203 is formed at the top of the clamping base 202. Symmetrically arranged clamping buckles 204 are movably arranged in the moving groove 203. A dial block 205 is fixedly provided on the side wall of the clamping buckle 204. The dial block 205 extends to the outside of the clamping base 202 through a through groove. A spring 211 is fixedly provided between the side wall of the clamping buckle 204 and the side wall of the moving groove 203. Clamping blocks 201 corresponding to the clamping bases 202 are fixedly provided on the side wall of the protective cover 102. A clamping groove 209 is formed at the bottom of the clamping block 201. A limiting groove 210 adapted to the clamping buckle 204 is provided on the side wall of the clamping groove 209. A clamping groove 107 adapted to the protective cover 102 is provided at the top of the mounting base plate 100. A clamping groove 107 adapted to the protective cover 102 is provided at the top of the mounting base plate 100.

[0032] Align the bottom of the protective cover 102 with the card slot 107 at the top of the mounting base plate 100. At the same time, align the clamping block 201 on the side wall of the protective cover 102 with the clamping base 202 at the top of the mounting base plate 100. Then, squeeze the dial 205 to retract the buckle 204, and then lower the protective cover 102 so that the bottom of the protective cover 102 is inserted into the card slot 107. The buckle 204 pops out under the action of the spring 211 and is snapped into the limiting slot 210 of the clamping groove 209 to complete the fixation. When it is necessary to repair or replace electrical components, just press the dial 205 to retract the buckle 204, and then the protective cover 102 can be easily removed for maintenance and repair work. By setting the clamping mechanism 200, the disassembly and assembly of the protective cover 102 become very convenient, and it can be completed only by simply pressing the dial 205 operation, which greatly improves the efficiency of maintenance and repair.

[0033] In this embodiment, a guide groove 206 is provided at the inner bottom of the moving groove 203, and a guide block 207 is movably provided in the guide groove 206. The top of the guide block 207 is fixedly connected to the bottom of the buckle 204.

[0034] Press the dial 205 to make the buckles 204 approach each other and retract, driving the guide block 207 to move along the guide groove 206, so that the movement of the buckle 204 is more stable, enhancing the stability and reliability of the device.

[0035] In this embodiment, a plurality of anti-slip strips 208 are fixedly provided on the opposite side walls of the dial 205.

[0036] By providing a plurality of anti-slip strips 208 on the dial 205, the anti-slip property of the dial 205 is enhanced, facilitating the staff to perform the extrusion operation on the dial 205 and improving the practicability of the device.

[0037] In this embodiment, a transparent observation window 103 is provided on one side of the protective cover 102.

[0038] The design of the transparent observation window 103 enables the staff to observe the operation state of the electrical component body 104 without removing the protective cover 102, facilitating the timely discovery of potential faults and taking measures in advance for treatment.

[0039] In this embodiment, mounting holes 101 are provided at the four corners of the mounting base plate 100.

[0040] Through the mounting holes 101, the device can be installed at any required position, enhancing the flexibility of the device and expanding the use range of the device.

[0041] Working process and principle: When this device is in use, first, the installation base plate 100 is firmly installed at a suitable position in the power plant through the installation holes 101 at its four corners. Then, the electrical component body 104 is installed on the top of the installation base plate 100 to ensure a reasonable layout of the electrical components, which is convenient for heat dissipation and maintenance. The protective cover 102 is covered on the top of the installation base plate 100 so that the electrical component body 104 is completely wrapped. The protective cover 102 is fixed to the installation base plate 100 by using the clamping mechanism 200. Align the bottom of the protective cover 102 with the card slot 107 on the top of the installation base plate 100. At the same time, align the clamping block 201 on the side wall of the protective cover 102 with the clamping base 202 on the top of the installation base plate 100. Then, squeeze the dial block 205 to retract the buckle 204, and then lower the protective cover 102 so that the bottom of the protective cover 102 is inserted into the card slot 107. The buckle 204 pops out under the action of the spring 211 and is stuck into the limiting slot 210 of the clamping slot 209 to complete the fixation. During the use process, start the motor 105 fixedly arranged on the top of the protective cover 102. The output end of the motor 105 drives the main bevel gear 306 to rotate. Utilize the meshing of the main bevel gear 306 and the secondary bevel gear 305 to drive the bidirectional lead screw 303 to rotate. The rotation of the bidirectional lead screw 303 causes the two moving boxes 301 to move symmetrically under the guidance of the guiding rod 304. When the moving box 301 moves, it drives the main bevel gear 307 to rotate. Through the meshing of the main bevel gear 307 and the secondary bevel gear 308, it drives the connecting shaft 309 to rotate, and further causes multiple fans 302 to rotate. As the moving box 301 moves, the fans 302 move back and forth inside the protective cover 102 to achieve all-round heat dissipation of the electrical component body 104. While the output end of the motor 105 drives the heat dissipation mechanism, it also drives one of the lead screws 405 to rotate through the first synchronous pulley 406 and the first synchronous belt 407. This lead screw 405 drives the other lead screw 405 to rotate synchronously through the second synchronous pulley 408 and the second synchronous belt 409. The rotation of the lead screw 405 causes the moving plate 403 to move up and down under the guidance of the limiting rod 401. When the moving plate 403 moves, the cleaning plate 404 on its side wall moves accordingly to wipe the heat dissipation net 106 back and forth, removing the dust and particulate matter adhering to the heat dissipation net 106 and keeping the heat dissipation net 106 unobstructed. Through the transparent observation window 103 on one side of the protective cover 102, the operating state of the electrical component body 104 and the working conditions of the heat dissipation mechanism and the dust removal mechanism can be observed in real time, which is convenient for timely discovery and handling of problems. When it is necessary to repair or replace the electrical components, just press the dial block 205 to retract the buckle 204, and then the protective cover 102 can be easily removed for maintenance and repair work, greatly improving the efficiency of maintenance and repair.
