Description

Technical Field

[0001] This invention belongs to the field of wind power generation technology, specifically an automatic fire extinguishing control cabinet for wind turbine generator sets. Background Technology

[0002] The control cabinet of a wind turbine generator set is the central nervous system of the entire power generation system. It is responsible for receiving mechanical energy from the wind turbine and converting it into electrical energy. The control cabinet typically includes key components such as frequency converters, inverters, controllers, and protection devices. These components work together to ensure the safe and stable operation of the wind turbine generator set and to maximize power generation efficiency.

[0003] In current technology, because the control cabinets of wind turbine generators are mostly placed in a centralized location for easy inspection, and some of them are placed at high altitudes, if one control cabinet catches fire due to excessive power and is not properly extinguished, the other control cabinets will also be affected, resulting in damage to the wind turbine generator and fire losses. Summary of the Invention

[0004] To overcome the shortcomings of existing technologies, this invention provides an automatic fire suppression control cabinet for wind turbine generator sets. This solves the problem of centralized placement of control cabinets in wind turbine generator sets, which could prevent the spread of fire to other control cabinets if one cabinet catches fire, ensuring timely detection and suppression of the fire and preventing additional losses.

[0005] The technical solution adopted by this invention to solve its technical problem is: an automatic fire extinguishing control cabinet for wind turbine generator sets, including a cabinet body. Multiple monitors are installed inside one side of the cabinet body, and multiple circuit breakers are installed on the inner wall of the cabinet body. Transmission wires are installed between each of the multiple circuit breakers and the multiple monitors. Fire extinguishing boxes are symmetrically fixedly installed on the outer wall of the cabinet body. The fire extinguishing boxes are used to spray liquefied carbon dioxide into the cabinet body to extinguish fire sources. A rear cover plate is hinged to the other side of the cabinet body. The top edge of the rear cover plate can be fixedly connected to the top of the cabinet body by screws. Multiple cable locking boxes are fixedly installed on the outer side of the rear cover plate. The cable locking boxes are used to fix the cable body to prevent the cable from being pulled and causing the internal terminals to loosen.

[0006] Preferably, a square box is provided on the outside of each of the multiple circuit breakers, and a control switch is fixedly installed inside each of the multiple square boxes. The push handles on the multiple circuit breakers correspond to the positions of the multiple control switches. A cable bundle is fixedly installed on one side of each of the multiple circuit breakers. Multiple covers are provided on the outside of the multiple circuit breakers and square boxes. The multiple covers are fixed to the inner wall of the cabinet by screws. The multiple covers enclose the multiple circuit breakers, cable bundles and square boxes inside.

[0007] Preferably, the cabinet is equipped with a liquid cooler, and the inner wall of the liquid cooler is fixedly installed with a gas distribution tube. The gas distribution tube divides multiple covers into separate working areas. The inner walls of multiple covers are provided with several heat dissipation holes. When the cabinet is operating normally, the airflow emitted by the liquid cooler passes through the gas distribution tube to cool the cables and devices inside the multiple covers. The multiple heat dissipation holes on the covers can accelerate heat dissipation.

[0008] Preferably, a baffle is fixedly installed inside the fire extinguishing box, a liquid inlet is fixedly installed on one side of the fire extinguishing box, a control sensor is fixedly installed on the other side of the fire extinguishing box, three telescopic cylinders are provided inside the fire extinguishing box, a control line is fixedly installed between the three telescopic cylinders, one end of the control line is fixedly connected to the inner wall of the control sensor, and a blocking rod is fixedly installed at the output end of the three telescopic cylinders. The blocking rod is slidably connected to the bottom inner wall of the fire extinguishing box and the bottom of the baffle.

[0009] Preferably, the inner wall of the fire extinguishing box is provided with two sets of air jets, and a siphon pipe is fixedly installed between the two sets of air jets. The blocking rod is placed directly above and in contact with one set of air jets, and one side of the inner wall of the fire extinguishing box is placed inside the cabinet.

[0010] Preferably, a push shaft is fixedly installed at one end of the outer side of the blocking rod, a conduit is provided inside the fire extinguishing box, a sound control button is fixedly installed at one end of the conduit, the position of the push shaft corresponds to the position of the sound control button, an alarm is fixedly installed at one end of the conduit, and the alarm is placed at the bottom outer side of the cabinet.

[0011] Preferably, the top of the wire locking box is rotatably connected to a handle, and one end of the handle is provided with a wire locking arc block, the outer edge of which is slidably connected to the inner wall of the wire locking box.

[0013] Preferably, a crossbar is fixedly installed between the two support legs.

[0014] Preferably, a front panel is rotatably connected to one side of the cabinet.

[0015] The beneficial effects of this invention are as follows:

[0016] 1. The automatic fire extinguishing control cabinet for wind turbine generator sets of the present invention uses a control sensor to control three telescopic cylinders to move and open a blocking rod. When the blocking rod moves to a certain position at the bottom of the baffle, the siphon pipe draws out carbon dioxide at the top of the baffle through one set of jet nozzles, and then sprays it out from another set of siphon pipes to extinguish the fire source. Through the pipe direction setting of the siphon pipe, the drawn carbon dioxide can be sprayed into the cabinet body.

[0032] To make the technical means, creative features, objectives and effects of this invention easier to understand, the invention will be further described below in conjunction with specific embodiments.

[0033] like Figures 1 to 12 As shown in the figure, an automatic fire extinguishing control cabinet for a wind turbine generator set according to an embodiment of the present invention includes a cabinet body 2. Multiple monitors 5 are installed inside one side of the cabinet body 2. Multiple circuit breakers 15 are installed on the inner wall of the cabinet body 2. Transmission wires 16 are installed between the multiple circuit breakers 15 and the multiple monitors 5. Fire extinguishing boxes 9 are symmetrically fixedly installed on the outer wall of the cabinet body 2. The fire extinguishing boxes 9 are used to spray liquefied carbon dioxide into the cabinet body 2 to extinguish the fire source. A rear cover plate 4 is hinged to the other side of the cabinet body 2. The top edge of the rear cover plate 4 can be fixedly connected to the top of the cabinet body 2 by screws. Multiple cable locking boxes 6 are fixedly installed on the outer side of the rear cover plate 4. The cable locking boxes 6 are used to fix the cable body to prevent the cable from being pulled and causing the internal terminals to loosen.

[0034] Before use, thread the cable through the rear cover plate 4 and connect the cable terminals to the circuit breaker 15. After wiring, rotate the rear cover plate 4 and use screws to fix the top of the rear cover plate 4 to the top of the cabinet 2. After fixing, press the cable locking box 6 to lock and fix the exposed cable entry end outside the cabinet 2. This prevents external force from affecting the normal operation of the connection terminal, and also fixes the cable, making the cable distribution inside the cabinet 2 clear and preventing the accumulation of excess cable inside the cabinet 2. It also avoids the risk of leakage and cross-current due to cable accumulation. When using, the circuit breaker 15... The cable is monitored to ensure it is operating normally. The detected information is then transmitted to the monitor 5 via the transmission wire 16 for feedback display, allowing operators to view and record the data. If the power in the cable is too high and causes a fire inside the control cabinet due to overload, the circuit breaker 15 disconnects the power to the cable. Subsequently, the two fire suppression boxes 9 are controlled to spray carbon dioxide into the cabinet 2 for fire suppression. At the same time, the fire suppression boxes 9 emit an audible signal to prompt operators to carry out emergency repairs on the control cabinet, thus protecting the control cabinet. It should be noted that carbon dioxide fire suppression leaves no residue and will not cause secondary damage to the control cabinet. It also facilitates cleanup afterward.

[0035] like Figures 5 to 6 As shown, a box 17 is provided on the outside of each of the multiple circuit breakers 15, and a control switch 18 is fixedly installed inside each of the multiple box 17. The push handles on the multiple circuit breakers 15 correspond to the positions of the multiple control switches 18. A cable bundle 14 is fixedly installed on one side of each of the multiple circuit breakers 15. Multiple covers 10 are provided on the outside of the multiple circuit breakers 15 and the box 17. The multiple covers 10 are fixed to the inner wall of the cabinet 2 by screws. The multiple covers 10 enclose the multiple circuit breakers 15, the cable bundle 14 and the box 17 inside.

[0036] During wiring, the cable is passed through the housing 10, and the cable terminals are bundled in the cable tie 14. The cable tie 14 is then fixed in the cabinet 2 with screws, covering the circuit breaker 15, the cable tie 14, and the square box 17. The circuit breaker 15 then monitors whether the cable is operating normally. The detected information is then transmitted to the monitor 5 for feedback display via the transmission wire 16. When the power of the cable is too high and causes a fire inside the control cabinet due to overload, the circuit breaker 15 disconnects the power to the cable. The push handle of the circuit breaker 15 will then trip, causing the push handle of the circuit breaker 15 to press against the control switch 18 inside the square box 17, thereby controlling the fire suppression box 9 to extinguish the fire inside the cabinet 2. It should be noted that the location of the control switch 18 corresponds to the location where the push handle of the circuit breaker 15 trips, and the specific location and the distance between them need to be calculated.

[0037] like Figures 4 to 5As shown, a liquid cooler 12 is installed inside the cabinet 2. A gas distribution tube 11 is fixedly installed on the inner wall of the liquid cooler 12. The gas distribution tube 11 divides multiple covers 10 into separate working areas. Several heat dissipation holes 13 are opened on the inner wall of each of the multiple covers 10.

[0038] When the cabinet 2 is operating normally, the airflow emitted by the liquid cooler 12 passes through the air distribution tube 11 to cool the cables and devices inside the multiple covers 10. The multiple heat dissipation holes 13 on the covers 10 can accelerate heat dissipation and play a role in heat dissipation, preventing damage to the internal components of the control cabinet due to internal overheating, which could lead to fire and losses.

[0039] like Figures 7 to 8 As shown, a baffle 23 is fixedly installed inside the fire extinguishing box 9. A liquid inlet 24 is fixedly installed on one side of the fire extinguishing box 9, and a control sensor 26 is fixedly installed on the other side of the fire extinguishing box 9. Three telescopic cylinders 27 are installed inside the fire extinguishing box 9. A control line 28 is fixedly installed between the three telescopic cylinders 27. One end of the control line 28 is fixedly connected to the inner wall of the control sensor 26. A blocking rod 29 is fixedly installed at the output end of the three telescopic cylinders 27. The blocking rod 29 is slidably connected to the bottom inner wall of the fire extinguishing box 9 and the bottom of the baffle 23.

[0040] When the push handle of the circuit breaker 15 is pressed against the control switch 18, the control switch 18 controls the operation of the control sensor 26. At the same time, the control sensor 26 controls the operation of the three telescopic cylinders 27 through the control line 28. When the three telescopic cylinders 27 operate, they drive the blocking rod 29 to move and open. When the blocking rod 29 moves to a certain position at the bottom of the baffle 23, the carbon dioxide at the top of the baffle 23 will flow out from the fire extinguishing box 9 and enter the cabinet 2 to spray and extinguish the fire source. When the carbon dioxide in the fire extinguishing box 9 is used up, the operator can introduce new carbon dioxide through the liquid inlet 24. It should be noted that the volume of carbon dioxide stored in the fire extinguishing box 9 needs to be actually calculated.

[0041] like Figures 8 to 9 As shown, the inner wall of the fire extinguishing box 9 is provided with two sets of air jets 30, and a siphon pipe 31 is fixedly installed between the two sets of air jets 30. The blocking rod 29 is placed directly above and attached to one of the sets of air jets 30. One side of the inner wall of the fire extinguishing box 9 is placed inside the cabinet 2.

[0042] When the blocking rod 29 is moved open, the siphon pipe 31 draws out the carbon dioxide in the fire extinguishing box 9 through one set of jet nozzles 30, and then sprays it out from another set of siphon pipes 31. Through the pipe orientation of the siphon pipe 31, the drawn carbon dioxide can be sprayed into the cabinet 2.

[0043] like Figures 7 to 9As shown, a push shaft 33 is fixedly installed on one side of the blocking rod 29. A conduit 25 is installed inside the fire extinguishing box 9. A sound control button 32 is fixedly installed on one end of the conduit 25. The position of the push shaft 33 corresponds to the position of the sound control button 32. An alarm 3 is fixedly installed on one end of the conduit 25. The alarm 3 is located at the bottom of the outer side of the cabinet 2.

[0044] When the blocking rod 29 moves open, it drives the push shaft 33 to move backward together. As the push shaft 33 moves, it gradually contacts the sound control button 32. When the push shaft 33 contacts and presses the sound control button 32, the sound control button 32 controls the alarm 3 to sound an alarm through the conduit 25 to remind the workers so that they can carry out rescue and repair as soon as possible and reduce losses.

[0045] like Figures 10 to 11 As shown, a rotating handle 19 is rotatably connected to the top of the wire lock box 6. A wire locking arc block 20 is provided at one end of the rotating handle 19. The outer edge of the wire locking arc block 20 is slidably connected to the inner wall of the wire lock box 6.

[0046] When locking the cable, turn the handle 19, which will cause the locking arc block 20 to move down. When the locking arc block 20 contacts the upper surface of the cable inside the locking box 6, it stops moving. At this time, the cable will be locked between the two, thus fixing the cable. On the one hand, this prevents external force from pulling and affecting the normal operation of the terminal. On the other hand, fixing the cable body makes the distribution of the cables in the cabinet 2 clear and prevents the accumulation of cables due to excess cable body inside the cabinet 2. It also avoids the risk of leakage and cross-current due to cable accumulation.

[0047] like Figures 10 to 12 As shown, two slots 8 are symmetrically fixedly installed on the top of one side of the rear cover plate 4. The inner walls of the two slots 8 are rotatably connected to the rotating shafts 22, and the outer walls of the two rotating shafts 22 are fixedly installed with the support legs 21.

[0048] During maintenance, first loosen the multiple lock boxes 6, remove the screws connecting the back cover 4 and the cabinet 2, rotate the support leg 21 in the slot 8 out through the pivot 22, and then rotate the back cover 4 at the bottom of one side of the cabinet 2. The back cover 4 will then open, and the inside of the cabinet 2 will be exposed. Then the maintenance personnel will carry out maintenance on the inside of the cabinet 2. By opening the support leg 21, the back cover 4 can be rotated open and placed in a horizontal position, which serves to support the back cover 4 and prevent damage to the back cover 4.

[0049] like Figures 10 to 12 As shown, a crossbar 7 is fixedly installed between the two support legs 21.

[0050] The two support legs 21 are connected by a crossbar 7, which provides stability to the rear cover plate 4 when it is supported by the support legs 21, making it more stable.

[0051] like Figures 1 to 2 As shown, a front panel 1 is rotatably connected to one side of the cabinet 2.

[0052] During operation, the operator can observe the control cabinet through the front panel 1, which can prevent dust from entering the cabinet 2 and accumulating. The front panel 1 is designed to block dust and facilitate observation of the operation.

[0053] Working principle: Before use, pass the cable through the rear cover plate 4 and connect the cable terminals to the circuit breaker 15. After wiring, rotate the rear cover plate 4 and use screws to fix the top of the rear cover plate 4 to the top of the cabinet 2. After fixing, press the cable locking box 6 to lock and fix the exposed cable entry end outside the cabinet 2. This prevents external force from affecting the normal operation of the connection terminal, and also fixes the cable, making the cable distribution inside the cabinet 2 clear and preventing the accumulation of excess cable inside the cabinet 2. It also avoids... Due to the risk of leakage and cross-current caused by cable accumulation, the circuit breaker 15 monitors the cables to ensure they are operating normally. The detected information is then transmitted to the monitor 5 via the transmission line 16 for feedback display, allowing operators to view and record the data. If excessive power in the cables causes an overload and fire inside the control cabinet, the circuit breaker 15 disconnects the power to the cables. It then controls two fire suppression boxes 9 to spray carbon dioxide into the cabinet 2 for fire suppression. Simultaneously, the fire suppression boxes 9 emit an audible warning to prompt operators to repair and salvage the control cabinet, thus protecting it.

[0054] The cable is passed through the housing 10, and the cable terminals are bundled in the cable tie 14. The cable tie 14 is then fixed in the cabinet 2 with screws, covering the circuit breaker 15, the cable tie 14, and the square box 17. The circuit breaker 15 then monitors whether the cable is operating normally. The detected information is then transmitted to the monitor 5 for feedback display via the transmission wire 16. When the power of the cable is too high and causes a fire inside the control cabinet due to overload, the circuit breaker 15 disconnects the power to the cable. The push handle of the circuit breaker 15 will then trip, causing the push handle of the circuit breaker 15 to press the control switch 18 inside the square box 17, thereby controlling the fire suppression box 9 to extinguish the fire inside the cabinet 2.

[0055] When the cabinet 2 is operating normally, the airflow emitted by the liquid cooler 12 passes through the air distribution tube 11 to cool the cables and devices inside the multiple covers 10. The multiple heat dissipation holes 13 on the covers 10 can accelerate heat dissipation and play a role in heat dissipation, preventing damage to the internal components of the control cabinet due to internal overheating, which could lead to fire and losses.

[0056] When the push handle of the circuit breaker 15 is pressed against the control switch 18, the control switch 18 controls the operation of the control sensor 26. At the same time, the control sensor 26 controls the operation of the three telescopic cylinders 27 through the control line 28. When the three telescopic cylinders 27 operate, they drive the blocking rod 29 to move and open. When the blocking rod 29 moves to a certain position at the bottom of the baffle 23, the carbon dioxide at the top of the baffle 23 will flow out from the fire extinguishing box 9 and enter the cabinet 2 to spray and extinguish the fire source. When the carbon dioxide in the fire extinguishing box 9 is used up, the operator can introduce new carbon dioxide through the liquid inlet 24.

[0057] When the blocking rod 29 is moved open, the siphon pipe 31 draws out the carbon dioxide in the fire extinguishing box 9 through one set of jet nozzles 30, and then sprays it out from another set of siphon pipes 31. Through the pipe orientation of the siphon pipe 31, the drawn carbon dioxide can be sprayed into the cabinet 2.

[0058] When the blocking rod 29 moves open, it drives the push shaft 33 to move backward together. As the push shaft 33 moves, it gradually contacts the sound control button 32. When the push shaft 33 contacts and presses the sound control button 32, the sound control button 32 controls the alarm 3 to sound an alarm through the conduit 25 to remind the workers so that they can carry out rescue and repair as soon as possible and reduce losses.

[0059] When locking the cable, turn the handle 19, which will cause the locking arc block 20 to move down. When the locking arc block 20 contacts the upper surface of the cable inside the locking box 6, it stops moving. At this time, the cable will be locked between the two, thus fixing the cable. On the one hand, this prevents external force from pulling and affecting the normal operation of the terminal. On the other hand, fixing the cable body makes the distribution of the cables in the cabinet 2 clear and prevents the accumulation of cables due to excess cable body inside the cabinet 2. It also avoids the risk of leakage and cross-current due to cable accumulation.

[0060] During maintenance, first loosen the multiple lock boxes 6, remove the screws connecting the back cover 4 and the cabinet 2, rotate the support leg 21 in the slot 8 out through the pivot 22, and then rotate the back cover 4 at the bottom of one side of the cabinet 2. The back cover 4 will then open, and the inside of the cabinet 2 will be exposed. Then the maintenance personnel will carry out maintenance on the inside of the cabinet 2. By opening the support leg 21, the back cover 4 can be rotated open and placed in a horizontal position, which serves to support the back cover 4 and prevent damage to the back cover 4.

[0061] The two support legs 21 are connected by a crossbar 7, which provides stability to the rear cover plate 4 when it is supported by the support legs 21, making it more stable.

[0062] Operators can observe the control cabinet through the front panel 1, which prevents dust from entering the cabinet 2 and accumulating. The front panel 1 serves to block dust and facilitate observation during operation.

[0063] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
