Description

Technical Field

[0001] This utility model relates to the field of SSS (Self-Switching Switchgear), and in particular to an intelligent high and low voltage switchgear control device. Background Technology

[0002] Low-voltage switchgear is commonly used low-voltage switchgear. High and low voltage switchgear are suitable for power plants, petroleum, chemical, metallurgy, textile, high-rise buildings and other industries for power transmission, distribution and power conversion. With the continuous improvement of science and technology, high and low voltage switchgear is also developing towards intelligence. Intelligent low-voltage switchgear is generally installed outdoors.

[0003] Patent CN214673511U discloses an intelligent control high and low voltage switchgear, including a high and low voltage switchgear body. A rain cover is fixedly connected to the upper surface of the switchgear body. The switchgear body has ventilation holes. Four air-collecting pipes are embedded in the upper surface of the rain cover. Air-supply pipes are fixedly connected to the lower ends of the air-collecting pipes. Two piston housings are fixedly connected to the lower ends of the air-supply pipes. An automatic shielding mechanism is installed inside the piston housings. Under atmospheric pressure, a connecting mechanism within the automatic shielding mechanism pushes a partition to automatically block the ventilation holes, thus preventing raindrops from entering the switchgear body through the ventilation holes when the wind force exceeds level four. This prevents damage to the electrical components inside the switchgear body and ensures the safety of the electrical components within the switchgear body. While the lifespan of components is affected by the wind, when the wind force is greater than level four, the piston can be driven by the wind to push the push rod up and down along the vertical movable groove. The push rod then drives the connecting rod to move up and down, thereby sealing the heat dissipation holes through the partition fixed to the bottom of the connecting rod, thus preventing raindrops from directly entering the high and low voltage switchgear body through the heat dissipation holes. However, when the wind force is less than level four outdoors, the wind force in the wind-gathering duct decreases, which reduces the thrust on the piston and the pressure on the support spring. As a result, the support spring rebounds, and the upward displacement of the partition no longer obstructs the heat dissipation holes. At this time, raindrops may enter the high and low voltage switchgear body through the heat dissipation holes along the side wall of the high and low voltage switchgear body, which may cause a short circuit in the high and low voltage switchgear body and may also affect the lifespan of the high and low voltage switchgear body.

[0004] Therefore, it is necessary to provide a new intelligent high and low voltage switchgear control device to solve the above-mentioned technical problems. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides an intelligent high and low voltage switch control device.

[0006] The intelligent high and low voltage switchgear control equipment provided by this utility model includes: a high and low voltage switchgear body, and a heat dissipation component. The heat dissipation component is detachably connected to the side wall of the high and low voltage switchgear body near the bottom end through a limiting component. The heat dissipation component includes a vent plate, which is detachably connected to the side wall of the high and low voltage switchgear body. The vent plate has multiple vent holes. A guide plate is integrally connected to the side wall of the vent plate. A rain shield is integrally connected to the upper surface of the guide plate. Two cooling fans are detachably connected to the side wall of the rain shield. A duct is inserted through one side of the guide plate and passes through the vent plate.

[0007] Preferably, the limiting component includes a driving member, the side wall of which is attached to the outer side wall of the high and low voltage switchgear body, the other end of which is inserted into the high and low voltage switchgear body, and a gear is welded to one end of the driving member inserted into the high and low voltage switchgear body. A limiting member that meshes with the gear is rotatably connected to the inner side wall of the high and low voltage switchgear body, and the side wall of the rain shield is provided with an insertion groove that matches the limiting member.

[0008] Preferably, the driving component includes a rotating rod that passes between the outer wall of the high and low voltage switchgear body and the vent plate. A knob is slidably connected to the rotating rod. A limit plate is integrally connected to the end of the rotating rod away from the high and low voltage switchgear body. A spring is provided between the end of the knob away from the limit plate and the limit plate. The two ends of the spring are respectively attached to the limit plate and the inner wall of the knob.

[0009] Preferably, the guide plate has a guide groove, which is inclined, and one end of the guide tube is inserted into the guide groove.

[0010] Preferably, the cooling fan includes a mounting housing, which is threaded to the side wall of the rain shield. A drive motor is bolted to the side of the mounting housing away from the vent plate. A rotating shaft is welded to the output end of the drive motor. The end of the rotating shaft away from the drive motor is rotatably connected to the inner side wall of the mounting housing.

[0011] Preferably, the limiting member includes a driven wheel, and a plug rod is integrally connected to the side wall of the driven wheel, the plug rod being arc-shaped.

[0012] Compared with related technologies, the intelligent high and low voltage switchgear control equipment provided by this utility model has the following beneficial effects:

[0013] 1. By incorporating a structure consisting of a guide plate and a rain shield, rainwater is guided into the guide channel and discharged through a conduit when water enters through the vent, preventing rainwater from directly seeping into the main body of the high and low voltage switchgear. Even in strong winds, the rain shield effectively blocks rainwater, significantly improving the equipment's rainproof capability, preventing electrical faults caused by rainwater, and ensuring safe operation of the equipment.

[0014] 2. The heat dissipation assembly is equipped with a cooling fan and a baffle plate, which can effectively prevent rainwater intrusion while ensuring ventilation and heat dissipation. At the same time, the cooling fan can increase the resistance of rainwater entering the main body of the high and low voltage switchgear. When heat dissipation is needed, the fan can actively enhance air circulation; and when encountering severe weather, the rain shield can automatically isolate rainwater, realizing intelligent adaptive control under different environmental conditions, and improving the stability and reliability of the equipment in complex outdoor environments.

[0015] 3. The heat dissipation component is connected to the side wall of the high and low voltage switchgear body by a limiting component consisting of knobs, gears, and plug rods. The structure is simple and easy to disassemble and assemble, which enables quick fixing and release of the vent plate, greatly simplifying the installation and maintenance process, reducing maintenance costs, improving the maintainability of the equipment and the efficiency of on-site operation, and is suitable for a variety of application scenarios.

[0023] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0024] Please refer to the following: Figure 1 — Figure 6 ,in, Figure 1 A schematic diagram of the overall structure of the intelligent high and low voltage switchgear control equipment provided by this utility model; Figure 2 A partial structural schematic diagram of the intelligent high and low voltage switchgear control equipment provided by this utility model; Figure 3 A cross-sectional schematic diagram of the cooling fan structure of the intelligent high and low voltage switchgear control equipment provided by this utility model; Figure 4 Partial structural cross-sectional view of the intelligent high and low voltage switchgear control equipment provided by this utility model; Figure 5 for Figure 2 Enlarged view of point a shown; Figure 6 A schematic diagram of the limit component of the intelligent high and low voltage switch control equipment provided by this utility model.

[0025] In practical implementation, an intelligent high and low voltage switchgear control device has the following structure: Figure 1 — Figure 6 As shown, it includes: a high and low voltage switchgear body 1, and a heat dissipation component 2. The heat dissipation component 2 is connected to the side wall of the high and low voltage switchgear body 1 near the bottom end by multiple limiting components 3. The heat dissipation component 2 includes a vent plate 21, which is connected to the side wall of the high and low voltage switchgear body 1. Multiple vent holes 22 are opened in the vent plate 21. A guide plate 23 is integrally connected to the side wall of the vent plate 21. A rain shield 24 is integrally connected to the upper end face of the guide plate 23. Two cooling fans 25 are screwed to the side wall of the rain shield 24. A duct 26 is inserted through one side of the guide plate 23 and passes through the vent plate 21.

[0026] It should be noted that the main body of the high and low voltage switchgear 1 is specifically the POWGRID-M model, which is an intelligent low-voltage switchgear designed and developed by Chint Group. The main body of the high and low voltage switchgear 1 adopts a standardized and modular design and has advanced functions such as intelligent temperature measurement, real-time detection and diagnosis. It can provide users with a reliable and convenient digital operation and maintenance solution and can be widely used in power generation, power distribution and motor control scenarios in various industries such as energy, industry and construction.

[0027] It should be noted that when rainwater flows into the high and low voltage switchgear body 1 through the vent plate 21, the rainwater will be collected by the rain baffle plate 24 and the guide plate 23, and the rainwater will be discharged through the pipe along the guide plate 23, thereby achieving a waterproof effect. Even if the wind is strong, the wind baffle can still effectively prevent rainwater from entering the high and low voltage switchgear body 1, improve the waterproof effect of the equipment, and extend the service life of the equipment.

[0028] The limiting component 3 includes a driving component 31. The side wall of the driving component 31 is attached to the outer side wall of the high and low voltage switch body 1. The other end of the driving component 31 is inserted into the high and low voltage switch body 1. A gear 32 is welded to one end of the driving component 31 inserted into the high and low voltage switch body 1. A limiting component 33 that meshes with the gear 32 is rotatably connected to the inner side wall of the high and low voltage switch body 1. The side wall of the rain shield 24 is provided with a plug groove 34 that matches the limiting component 33.

[0029] It should be noted that the four limiting components 3 are located at the four corners of the ventilated plate 21;

[0030] The limiting member 33 includes a driven wheel 331, and a plug rod 332 is integrally connected to the side wall of the driven wheel 331. The plug rod 332 is arranged in an arc shape.

[0031] The driving component 31 includes a rotating rod 311, which is inserted between the outer wall of the high and low voltage switch body 1 and the vent plate 21. A knob 312 is slidably connected to the rotating rod 311. A limit plate 313 is integrally connected to the end of the rotating rod 311 away from the high and low voltage switch body 1. A spring 314 is provided between the end of the knob 312 away from the limit plate 313 and the limit plate 313. The two ends of the spring 314 are respectively attached to the limit plate 313 and the inner wall of the knob 312.

[0032] It should be noted that the rotating rod 311 has an integrally connected slider on its side wall, and the knob 312 is slidably connected to the slider. It should be noted that there is a gap between the slider and the outer side wall of the high and low voltage switchgear body 1. The height of the gap is equal to the thickness of the side wall of the knob 312 adjacent to the gap. When the knob 312 is not subjected to external force, under the action of the spring 314, the side wall of the knob 312 adjacent to the high and low voltage switchgear body 1 is in contact with the outer side wall of the high and low voltage switchgear body 1. At this time, the knob 312 can rotate freely in the gap. The rotation of the knob 312 will not drive the rotating rod 311 to rotate.

[0033] It should be noted that when installing the vent plate 21, first install the rotating rod 311 on the side of the vent plate 21 adjacent to the main body 1 of the high and low voltage switchgear. Then install the vent plate 21 and the baffle plate. After the baffle plate is fully inserted into the main body 1 of the high and low voltage switchgear, first pull the knob 312. The knob 312 compresses the spring 314. Then rotate the knob 312. The knob 312 drives the gear 32 to rotate through the rotating rod 311. The gear 32 drives the driven wheel 331 to rotate, thereby inserting the plug rod 332 into the plug slot 34 to limit the position of the rain shield 24. Since the rain shield 24 and the vent plate 21 are integrally connected, the vent plate 21 is limited, which in turn limits the position of the heat dissipation component 2. When disassembling the heat dissipation component 2, simply pull out multiple knobs 312 in sequence and rotate them to pull out multiple plug rods 332 from their matching limiting slots to remove the heat dissipation component 2.

[0034] A guide groove 231 is provided inside the guide plate 23. The guide groove 231 is inclined, and one end of the guide tube 26 is inserted into the guide groove 231.

[0035] The cooling fan 25 includes a mounting housing 251, which is threaded to the side wall of the rain shield 24. A drive motor 252 is bolted to the side of the mounting housing 251 away from the vent plate 21. A rotating shaft 253 is welded to the output end of the drive motor 252. The end of the rotating shaft 253 away from the drive motor 252 is rotatably connected to the inner side wall of the mounting housing 251. Multiple fan blades 254 are inserted outside the rotating shaft 253, and the multiple fan blades 254 are arranged in a circular array with respect to the rotating shaft 253.

[0036] The circuits and controls involved in this utility model are all existing technologies, and will not be described in detail here.

[0037] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
