Description

Technical Field

[0001] The present invention relates to the technical field of power control cabinets, and particularly to a power control cabinet for power equipment. Background Art

[0002] As a key device in power technology, power control cabinets are widely used in the installation and operation of power equipment. A large number of modules with various electronic components are arranged inside its cabinet. During the operation of the control cabinet, a large number of electrical components work continuously, generating a large amount of heat. Moreover, the normal operation of these electrical components has strict requirements on the ambient temperature.

[0003] Regarding this, a power control cabinet with a temperature control and supervision adjustment function disclosed in the patent with the publication number "CN116454765B" regulates the temperature value inside the power control cabinet and supervises the temperature sensors that collect data to ensure the effectiveness of the collected data, which is helpful for accurately and reasonably regulating the temperature inside the power control cabinet.

[0004] However, during actual use, when the outside temperature is too high, the wind plates are in the open state for heat dissipation. However, when the control cabinet is in a semi-arid grassland area, sand and dust often enter the inside of the control cabinet along the air inlet. These dusts may accumulate on the circuit board, causing a short-circuit fault. In addition, insects, grass seeds, etc. in the semi-arid grassland area provide a rich food source for birds. Bird droppings, sand and dust, and the attached dust will adhere to the baffle, affecting the appearance. At the same time, the corrosiveness of bird droppings will erode the baffle, reducing its protection performance.

[0005] Therefore, this application proposes a power control cabinet for power equipment. Summary of the Invention

[0006] The purpose of the present invention is to solve the disadvantages existing in the prior art, and to propose a power control cabinet for power equipment.

[0007] To achieve the above purpose, the present invention adopts the following technical solutions: A power control cabinet for power equipment includes a control cabinet, four switch components, two flushing and filtering components, and two heat dissipation components; A base is fixedly connected to the lower part of the control cabinet, and a rain shelter is fixedly installed above the control cabinet. Two mounting rods are rotatably connected between the base and the control cabinet; two mounting plates are respectively arranged on both sides of the control cabinet, two heat dissipation openings are respectively arranged on both sides of the control cabinet, and two groups of sliding grooves are respectively arranged on both sides of the control cabinet; The four switch components are respectively used to control the opening and closing of the heat dissipation openings; The two flushing and filtering components are respectively used to flush the rain shelter and filter rainwater multiple times; Four heat dissipation components are respectively used for dissipating heat from the control cabinet.

[0008] Preferably, the switch component is composed of a switch board, a worm gear, and a worm. The switch board is rotatably connected to the heat dissipation port. The worm is fixedly connected to the mounting rod. The worm gear is rotatably connected to the control cabinet. The worm gear is fixedly connected to the switch board. The worm gear is meshed with the worm.

[0009] Preferably, the flushing and filtering component is composed of a piston cylinder, a first gear, and a water outlet pipe. The piston cylinder is fixedly installed on the control cabinet. The first gear is rotatably connected to the control cabinet. The water outlet pipe penetrates through the control cabinet and is rotatably connected and communicated with the piston cylinder. The water outlet pipe is fixedly connected to the first gear.

[0010] Preferably, the heat dissipation component is composed of heat dissipation water pipes, two heat dissipation frames, four blowers, and four fans. The two heat dissipation frames are respectively slidably connected to two groups of chutes. The four blowers are respectively fixedly installed on the two heat dissipation frames. The four fans are respectively rotatably connected to the two heat dissipation frames. The four blower drive shafts are respectively fixedly connected to the four fans. The two heat dissipation water pipes are respectively fixedly installed inside the control cabinet.

[0011] Preferably, two slide rails are fixedly connected above the control cabinet. Two racks are respectively slidably connected to the two slide rails. The two racks are respectively meshed with the two first gears. A second gear is rotatably connected to the control cabinet. The second gear is meshed with the first gear. The second gear is fixedly connected to the mounting rod.

[0012] Preferably, a water collecting tank is fixedly installed on the control cabinet. Double-shaft motors are respectively fixedly installed on both sides of the control cabinet. Two transmission shafts of the double-shaft motors are respectively fixedly connected with reciprocating lead screws. Slide rods are respectively fixedly connected pairwise between the four mounting plates. Sliders are respectively fixedly connected to both ends of the heat dissipation frame. The two sliders are respectively slidably connected to the reciprocating lead screws and the slide rods. Both ends of the heat dissipation water pipes are respectively arranged outside the control cabinet and are communicated with the water collecting tank.

[0013] Preferably, a piston is slidably connected inside the piston cylinder. An L-shaped piston rod is fixedly connected to the piston. The L-shaped piston rod is slidably connected to the piston cylinder. One end of the L-shaped piston rod away from the piston is fixedly connected to the heat dissipation frame. A water inlet pipe is arranged between the piston cylinder and the water collecting tank. Both ends of the water inlet pipe are respectively communicated and connected to the piston cylinder and the water collecting tank.

[0014] Preferably, check valves are provided at the joints where the piston cylinder is connected to the water outlet pipe and the water inlet pipe. A wind speed sensor is fixedly installed on the rain shelter, and two electric telescopic rods are fixedly installed on the rain shelter. The output ends of the two electric telescopic rods are respectively fixedly connected to two racks. A filter plate is fixedly connected to the water collection tank. A filter layer is provided in the water collection tank, and an in-built water pump is provided in the water collection tank.

[0015] The present invention has the following beneficial effects: Through the heat dissipation component, when the double-shaft motor drives the two reciprocating lead screws to rotate, the heat dissipation frame can reciprocate up and down on the two heat dissipation openings. The fans on the heat dissipation frame drive the fans to dissipate heat from the control cabinet. At the same time, the rainwater collected by the water collection tank flows in the heat dissipation water pipe under the action of the water pump for heat dissipation synchronously. At the same time, in cooperation with the fans, it can timely take away the heat on the surface of the heat dissipation water pipe and accelerate the speed of heat exchange, thus significantly improving the heat dissipation efficiency.

[0016] Through the flushing and filtering component, when the reciprocating lead screw drives the heat dissipation component to reciprocate up and down, the L-shaped piston rod can drive the piston to reciprocate under the drive of the heat dissipation frame. Under the action of the check valve, the water in the water collection tank enters the piston cylinder through the water inlet pipe, and then is sprayed back into the water collection tank through the water outlet pipe. Under the action of the filter plate and the filter layer, the rainwater in the water collection tank is filtered repeatedly, which can effectively prevent impurities from depositing in the heat dissipation water pipe and the water collection tank, ensure the smoothness of the heat dissipation water pipe and the heat dissipation efficiency, and ensure the stable and efficient operation of the heat dissipation and water circulation system of the entire power control cabinet.

[0017] Through the flushing and filtering component, when the wind speed sensor detects the approach of sand and dust, it controls the electric telescopic rod to push the rack, and the rack makes the first gear rotate, which can drive the water outlet pipe to rotate, so that the water outlet end of the water outlet pipe faces the rain shelter. The L-shaped piston rod can drive the piston to reciprocate under the drive of the heat dissipation frame. Under the action of the check valve, the water in the water collection tank enters the piston cylinder through the water inlet pipe, and then the water outlet pipe flushes the sand and bird droppings on the rain shelter to avoid affecting the appearance or allowing the bird droppings to erode the rain shelter.

[0018] Through the switch component, when the rack drives the first gear to rotate, it can make the second gear drive the worm on the mounting rod to rotate, so that the worm gear drives the switch plate to rotate, thus closing the heat dissipation opening. And because the water in the built-in heat dissipation water pipe still flows under the action of the water pump in the water collection tank at this time, and at the same time, under the action of the external sand and dust wind and air flow, it can also accelerate the heat dissipation outside the control cabinet synchronously. Therefore, it will not affect the normal heat dissipation of the control cabinet, and can effectively prevent sand and dust from entering the control cabinet through the heat dissipation opening and causing electrical component failures.

Detailed implementation manners

[0021] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. Embodiment 1:

[0022] Refer to Figures 6 - 9 , a power control cabinet for power equipment, including a control cabinet 1, four switch components, two flushing and filtering components, and two heat dissipation components; A base 2 is fixedly connected below the control cabinet 1, and the base 2 provides stable support for the entire device, ensuring that the control cabinet is placed stably in various environments. Two mounting plates 22 are respectively arranged on both sides of the control cabinet 1, and a rain shelter 3 is fixedly installed above the control cabinet 1, whose function is to effectively prevent rain from directly hitting the control cabinet and protect the internal electrical components from rain erosion. Two heat dissipation openings 18 are respectively arranged on both sides of the control cabinet 1, which are used for the exchange of air inside the control cabinet and the outside air to achieve the heat dissipation function; at the same time, two groups of chutes 31 are respectively arranged on both sides, providing tracks for the sliding of the heat dissipation frame 6.

[0023] The four switch components are respectively used to control the opening and closing of the heat dissipation openings 18; The two flushing and filtering components are respectively used to flush the rain shelter 3 and filter rainwater multiple times; The four heat dissipation components are respectively used to dissipate heat from the control cabinet 1.

[0024] The heat dissipation component is composed of heat dissipation water pipes 19, two heat dissipation frames 6, four fans 15 and four blowers 30. The two heat dissipation frames 6 are respectively slidably connected to two groups of chutes 31, the four fans 15 are respectively fixedly installed on the two heat dissipation frames 6, the four blowers 30 are respectively rotatably connected to the two heat dissipation frames 6, and the drive shafts of the four fans 15 are respectively fixedly connected to the four blowers 30. When the fans 15 are started, they drive the blowers 30 to rotate, accelerating air flow and enhancing the heat dissipation effect. The two heat dissipation water pipes 19 are respectively fixedly installed inside the control cabinet 1, and absorb the heat inside the control cabinet through water circulation to further assist in heat dissipation.

[0025] A water collection tank 4 is fixedly installed on the control cabinet 1, which is used to collect rainwater and provide water sources for heat dissipation and flushing. Double-shaft motors 5 are respectively fixedly installed on both sides of the control cabinet 1, and the two drive shafts of the double-shaft motors 5 are respectively fixedly connected with reciprocating lead screws 11. Slide rods 14 are respectively fixedly connected between the four mounting plates 22 in pairs, and sliders 29 are respectively fixedly connected to both ends of the heat dissipation frame 6, and the two sliders 29 are respectively slidably connected to the reciprocating lead screws 11 and the slide rods 14. The double-shaft motor 5 drives the reciprocating lead screw 11 to rotate, driving the heat dissipation frame 6 to reciprocate and slide on the chute 31, which can dissipate heat from the two heat dissipation openings 18. The two ends of the heat dissipation water pipe 19 are respectively arranged outside the control cabinet 1 and connected to the water collection tank 4. The built-in water pump in the water collection tank 4 conveys water into the heat dissipation water pipe 19 to form a water circulation. A filter plate 16 is fixedly connected to the water collection tank 4, and a filter layer is arranged inside the water collection tank 4, which is composed of various filter materials such as activated carbon and quartz sand, and can effectively filter the tiny particles, organic matters and peculiar smells in the water. The filter plate 16 and the filter layer jointly filter the collected rainwater to ensure that the water entering the heat dissipation water pipe 19 is clean and free of impurities.

[0026] In this embodiment, when the biaxial motor 5 drives the two reciprocating lead screws 11 to rotate, the heat dissipation frame 6 can reciprocate up and down on the two heat dissipation ports 18. The fan 15 on the heat dissipation frame 6 drives the fan 30 to dissipate heat from the control cabinet 1. At the same time, the rainwater collected by the water collection tank 4 flows in the heat dissipation water pipe 19 under the action of the water pump for heat dissipation synchronously. At the same time, in cooperation with the fan 30, it can timely take away the heat on the surface of the heat dissipation water pipe 19 and accelerate the heat exchange speed, thereby significantly improving the heat dissipation efficiency. Embodiment 2:

[0027] Different from Embodiment 1, referring to Figure 2 - Figure 5 and Figure 7 , this embodiment also has the following further content: The flushing and filtering assembly consists of a piston cylinder 8, a first gear 23, and a water outlet pipe 12. The piston cylinder 8 is fixedly installed on the control cabinet 1 and serves as an important component for water storage and transportation, providing pressure for subsequent flushing operations. The first gear 23 is rotatably connected to the control cabinet 1, and its rotation can drive the water outlet pipe 12 fixedly connected thereto to rotate. The water outlet pipe 12 passes through the control cabinet 1 and rotates and is connected to the piston cylinder 8, and the water outlet pipe 12 is fixedly connected to the first gear 23. It is responsible for guiding the water in the piston cylinder 8 to the rain shelter 3 or the water collection tank 4. Two slide rails 25 are fixedly connected above the control cabinet 1. Two racks 27 are respectively slidably connected to the two slide rails 25, and the two racks 27 are respectively meshed with the two first gears 23. The rotation of the first gear 23 is driven by the sliding of the rack 27.

[0028] A piston 28 is slidably connected in the piston cylinder 8. An L-shaped piston rod 21 is fixedly connected to the piston 28. The L-shaped piston rod 21 is slidably connected to the piston cylinder 8. One end of the L-shaped piston rod 21 away from the piston 28 is fixedly connected to the heat dissipation frame 6. When the heat dissipation frame 6 slides, it will drive the L-shaped piston rod 21 to move, thereby causing the piston 28 to slide in the piston cylinder 8. A water inlet pipe 20 is provided between the piston cylinder 8 and the water collection tank 4. Both ends of the water inlet pipe 20 are respectively connected to the piston cylinder 8 and the water collection tank 4 for introducing the water in the water collection tank 4 into the piston cylinder 8. Check valves are provided at the connection points of the piston cylinder 8 with the water outlet pipe 12 and the water inlet pipe 20. The check valves ensure that the water can only flow in a predetermined direction, ensuring the normal progress of the flushing and water circulation processes.

[0029] A wind speed sensor 7 is fixedly installed on the rain shelter 3 for real-time monitoring of the external wind speed. When the wind speed is too high, it means that there may be sand and dust approaching. At this time, protective measures need to be taken. Two electric telescopic rods 26 are also fixedly installed on the rain shelter 3, and the output ends of the two electric telescopic rods 26 are respectively fixedly connected to two racks 27. After the wind speed sensor 7 detects abnormal wind speed, it will control the electric telescopic rod 26 to act, push the rack 27 to slide, and then drive the first gear 23 to rotate, realizing the steering of the water outlet pipe 12 so that the water outlet of the water outlet pipe 12 faces the rain shelter 3.

[0030] It should be noted that the electric telescopic rod 26 can be controlled not only by the wind speed sensor 7. In actual application scenarios, the electric telescopic rod 26 can also be adjusted by means of the control buttons on the operation panel of the control cabinet 1. For example, during regular maintenance work, in order to ensure the effectiveness of the flushing system, the staff needs to finely adjust the angle of the water outlet pipe 12, and can directly operate the control buttons to drive the electric telescopic rod 26 to act.

[0031] In this embodiment, when the reciprocating lead screw 11 drives the heat dissipation component to reciprocate up and down, the L-shaped piston rod 21 can drive the piston 28 to reciprocate under the drive of the heat dissipation frame 6. Under the action of the one-way valve, the water in the water collection tank 4 enters the piston cylinder 8 through the water inlet pipe 20, and then is sprayed back into the water collection tank 4 through the water outlet pipe 12. Under the action of the filter plate 16 and the filter layer, the rainwater in the water collection tank 4 is filtered repeatedly, which can effectively prevent impurities from depositing in the heat dissipation water pipe 19 and the water collection tank 4, ensuring the smoothness of the heat dissipation water pipe 19 and the heat dissipation efficiency, and ensuring that the heat dissipation and water circulation systems of the entire power control cabinet can operate stably and efficiently. When the wind speed sensor 7 detects the approach of sand and dust, it controls the electric telescopic rod 26 to push the rack 27, and the rack 27 rotates the first gear 23, which can drive the water outlet pipe 12 to rotate, so that the water outlet end of the water outlet pipe 12 faces the rain shelter 3. And the L-shaped piston rod 21 can drive the piston 28 to reciprocate under the drive of the heat dissipation frame 6. Under the action of the one-way valve, the water in the water collection tank 4 enters the piston cylinder 8 through the water inlet pipe 20, and then the water outlet pipe 12 is used to wash the sand and bird droppings on the rain shelter 3 to prevent affecting the appearance or allowing the bird droppings to erode the rain shelter 3. Embodiment Three:

[0032] Refer to Figures 1 - 4 and Figure 8 Compared with Embodiment One and Embodiment Two, in this embodiment: There are two mounting rods 9 rotatably connected between the base 2 and the control cabinet 1, and the mounting rods 9 can rotate between the base 2 and the control cabinet 1.

[0033] The switch assembly consists of a switch board 13, a worm gear 10, and a worm 17. The switch board 13 is rotatably connected to the heat dissipation opening 18. The worm 17 is fixedly connected to the mounting rod 9. When the mounting rod 9 rotates, it can drive the worm 17 to rotate. The worm gear 10 is rotatably connected to the control cabinet 1 and is fixedly connected to the switch board 13. The worm gear 10 is fixedly connected to the switch board 13 through a round rod, and the round rod is arranged inside the outer wall of the control cabinet 1. When the worm gear 10 rotates, it can drive the switch board 13 to rotate. The worm gear 10 is meshed with the worm 17. When the worm 17 rotates, it can drive the worm gear 10 to rotate.

[0034] A second gear 24 is rotatably connected to the control cabinet 1. The second gear 24 is meshed with the first gear 23 and is fixedly connected to the mounting rod 9. When the first gear 23 rotates, it can cause the second gear 24 to drive the mounting rod 9 to rotate.

[0035] In this embodiment, when the rack 27 drives the first gear 23 to rotate, it can cause the second gear 24 to drive the worm 17 on the mounting rod 9 to rotate, so that the worm gear 10 drives the switch board 13 to rotate, thereby closing the heat dissipation opening 18. Since the water in the built-in heat dissipation water pipe 19 still flows under the action of the water pump in the water collection tank 4 at this time, and at the same time, under the action of the external sandstorm wind and airflow, the heat dissipation outside the control cabinet 1 can be accelerated synchronously. Therefore, it will not affect the normal heat dissipation of the control cabinet 1, and can effectively prevent sand and dust from entering the control cabinet 1 through the heat dissipation opening 18 and causing electrical component failures.

[0036] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution and inventive concept of the present invention, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
