Description

Technical Field

[0001] The utility model relates to the technical field of high-voltage switch cabinets, in particular to a high-voltage switch cabinet with a temperature control function. Background Art

[0002] High-voltage switchgear refers to electrical products with voltage levels ranging from 3.6kV to 550kV, which are used for switching, control or protection in power generation, transmission, distribution, power conversion and consumption of power systems. They mainly include high-voltage disconnectors and earthing switches, high-voltage load switches, high-voltage automatic reclosing and sectionalizers, high-voltage operating mechanisms, high-voltage explosion-proof distribution devices and high-voltage switchgear. A large number of distribution equipment are installed in high-voltage switchgear, and heat will accumulate in the distribution cabinet during continuous operation.

[0003] In order to ensure the working environment of the equipment in the high-voltage distribution cabinet, it is necessary to set up additional temperature control facilities in the distribution cabinet to assist in cooling the equipment in the distribution cabinet. The common temperature control equipment relies on the fan to cooperate with the air vents on the outside of the cabinet to form airflow in the distribution cabinet, and then the heat accumulated in the distribution cabinet is brought out through the airflow. The size of the airflow is affected by adjusting the speed of the fan, and then the heat dissipation efficiency of the equipment in the high-voltage distribution cabinet is adjusted, thereby realizing temperature control in the high-voltage distribution cabinet. However, in the actual working process, after a long period of continuous work, dust is inevitably accumulated on the dustproof plate outside the fan, and the dustproof baffle located on the inside of the cabinet is difficult to clean. Secondly, too much dust accumulates on the dustproof plate, which can only be disassembled for cleaning. In the existing high-voltage switch cabinet with temperature control function, the dustproof plate is mostly fixed on the outside of the fan mechanism by bolt connectors, and the disassembly and assembly operation is relatively cumbersome. For this reason, we designed a high-voltage switch cabinet with temperature control function to solve the above problems. Utility Model Content

[0004] The purpose of the utility model is to address the deficiencies in the prior art and provide a high-voltage switch cabinet with a temperature control function. By setting a deflection port and an assembly frame as well as a clamping block and a spring clip, the dustproof frame and the dustproof plate can be flipped over, thereby solving the problem that the dustproof baffle located inside the cabinet is difficult to clean and the dustproof plate is complicated to disassemble and assemble.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a high-voltage switchgear with a temperature control function, comprising a high-voltage distribution cabinet body, both sides of the high-voltage distribution cabinet body are provided with evenly distributed air vents, and the external movable sleeve of the high-voltage distribution cabinet body is provided with a cabinet door corresponding to the position of the air vent, a deflection opening is provided in the middle of the cabinet door, and an assembly frame located inside the deflection opening is sleeved in the cabinet door, the bottom end of the assembly frame is movably connected to the air vent through a rotating rod, a servo motor located above the assembly frame is fixedly connected to the inner side of the air vent, a driving shaft of the servo motor is fixedly connected to the middle part of the top of the assembly frame, a cooling fan is arranged on the inner side of the assembly frame, and a dustproof frame is sleeved in the assembly frame, and evenly distributed dustproof guard plates are fixedly connected to the dustproof frame.

[0009] Preferably, a dust accumulation groove is provided in the dustproof guard plate, and the inner side wall of the dust accumulation groove is recessed and inclined toward the middle of the dustproof guard plate.

[0010] Preferably, a clamping block is provided on the inner movable sleeve of the assembly frame, and a clamping groove matching the shape of the clamping block is provided on the outside of the dustproof frame.

[0011] Preferably, a movable groove matching the shape of the clamping block is formed in the assembly frame, and a spring sheet located inside the movable groove is fixedly connected to the outside of the clamping block.

[0015] The beneficial effects of the utility model are:

[0016] The utility model provides a deflection port, a servo motor, an assembly frame and a cooling fan so that the high-voltage switch cabinet with a temperature control function can flip the cooling fan, and flip the dust protection plate originally located on the inside of the cabinet door to the outside of the cabinet door, which can be convenient for staff to wipe and clean the dust protection plate originally located on the inside of the cabinet door. At the same time, the flipped cooling fan can blow air toward the inside of the high-voltage distribution cabinet body, thereby blowing off dust accumulated on the equipment in the high-voltage distribution cabinet body, and further improving the heat dissipation effect of the equipment in the high-voltage distribution cabinet body.

[0017] By providing a dustproof frame, a dustproof guard plate and a dust accumulation groove, the dustproof guard plate of the high-voltage switch cabinet with temperature control function can be installed on both sides of the cooling fan through the dustproof frame. On the one hand, the airflow induced by the cooling fan when working is reduced in dust, and on the other hand, the outside of the cooling fan is protected. At the same time, the dust accumulation groove opened on the dustproof guard plate can also prevent dust from falling during the flipping of the cooling fan, and it is convenient for the staff to wipe the dustproof guard plate.

[0018] By setting the card blocks, spring pieces and card slots, the high-voltage switch cabinet with temperature control function can disassemble and assemble the dustproof frame as a whole.

The disassembly and assembly operations of the dustproof frame as a whole are simple and convenient, and easy for staff to operate.

[0019] In summary, the utility model has the advantages of being convenient for staff to wipe and clean the dustproof guard plate originally located on the inside of the cabinet door, preventing dust from being scattered during the flipping of the cooling fan, and the overall disassembly and assembly of the dustproof frame are simple and convenient.

[0033] Embodiment 1

[0034] like Figures 1 to 9 As shown, the present embodiment provides a high-voltage switch cabinet with a temperature control function, comprising a high-voltage distribution cabinet body 1, both sides of the high-voltage distribution cabinet body 1 are provided with evenly distributed air vents 3, and the outer movable sleeve of the high-voltage distribution cabinet body 1 is provided with a cabinet door 2 corresponding to the position of the air vent 3, a deflection opening 4 is provided in the middle of the cabinet door 2, and an assembly frame 5 located on the inner side of the deflection opening 4 is sleeved in the cabinet door 2, the bottom end of the assembly frame 5 is movably connected to the air vent 3 through a rotating rod 10, a servo motor 7 located above the assembly frame 5 is fixedly connected to the inner side of the air vent 3, a driving shaft of the servo motor 7 is fixedly connected to the middle part of the top of the assembly frame 5, a cooling fan 12 is arranged on the inner side of the assembly frame 5, and a dustproof frame 6 is sleeved in the assembly frame 5, and evenly distributed dustproof guard plates 11 are fixedly connected to the dustproof frame 6.

[0035] In this embodiment, if Figure 2 As shown, the inner side of the cabinet door 2 is fixedly connected to the limit seats 9 symmetrically distributed on both sides of the deflection opening 4, and one side of the assembly frame 5 is fixedly connected to a limit plate 8 located on the inner side of the cabinet door 2. The limit seat 9 is provided with a groove that matches the shape of the limit plate 8. During the flipping activity on the inner side of the deflection opening 4, the assembly frame 5 will drive the limit plates 8 on its sides to move together. When the assembly frame 5 is flipped as a whole to be parallel to the cabinet door 2, the limit plate 8 can be embedded in the groove on the inner side of the limit seat 9 at the corresponding position, thereby realizing the limitation of the assembly frame 5 during the flipping process.

[0036] In this embodiment, if Figure 3 As shown, there are two groups of dustproof frames 6, and the two groups of dustproof frames 6 are symmetrically distributed on the outside of the cooling fan 12. The dustproof frame 6 is a frame-like structure, which is adapted to the inner space of the assembly frame 5, so as to facilitate the installation of the dustproof guard plate 11 on the inner side of the assembly frame 5. At the same time, the assembly frame 5 can cooperate with the dustproof frame 6 and the dustproof guard plate 11 to wrap the cooling fan 12, so that there is a protective structure on the side of the cooling fan 12 facing the outside of the cabinet door 2, so as to prevent the cooling fan 12 from being dangerous or damaged during operation.

[0037] In this embodiment, if Figure 8As shown, an angle is set between the dustproof guard plate 11 and the dustproof frame 6, and the end of the dustproof guard plate 11 tilted downward faces the outside of the dustproof frame 6, and the end of the dustproof guard plate 11 tilted downward is provided with an arc surface, so that air can pass through the gap between the dustproof guard plates 11. Dust will adhere to the dustproof guard plate 11 during the passage of air. The angle between the dustproof guard plate 11 and the dustproof frame 6 forms an inclined surface on the outside of the dustproof guard plate 11, which increases the contact surface between the dustproof guard plate 11 and the dustproof frame 6 during the passage of air, ensures contact with the air, and also provides a position for the accumulated dust to adhere to, avoiding the accumulated dust being blown by the airflow to generate large dust. The arc surface of the lower end face of 11 is more rounded, which can avoid the end structure of 11 being too sharp, and is convenient for the staff to take 11 and 6 as a whole.

[0038] In this embodiment, if Fig. 9 As shown, a dust accumulation groove 22 is provided in the dust protection plate 11, and the inner side wall of the dust accumulation groove 22 is concave and inclined toward the middle part of the dust protection plate 11. The dust accumulation groove 22 provided in the dust protection plate 11 can expand the surface area of ​​the outside of the dust protection plate 11, so that more dust can be received and stored. In this way, during the deflection movement of the dust protection plate 11 following the assembly frame 5, dust is not easily dropped directly due to vibration, thereby polluting the interior of the high-voltage distribution cabinet body 1. The inclination of the side wall of the dust accumulation groove 22 can make the side of the dust accumulation groove 22 present a trumpet shape that expands toward the outside of the dust protection plate 11, thereby expanding the gap in the edge area of ​​the dust accumulation groove 22, making it convenient for the staff to wipe and clean the dust accumulation groove 22.

[0039] In this embodiment, if Figures 3 to 5 As shown, the inner movable sleeve of the assembly frame 5 is provided with a card block 14, and the outside of the dustproof frame 6 is provided with a card slot 13 that matches the shape of the card block 14. After the dustproof frame 6 is sleeved on the inner side of the assembly frame 5, the card block 14 on the inner side of the assembly frame 5 can be embedded in the card slot 13 on the outside of the dustproof frame 6 under the action of the elastic force of the spring piece 17, so that the card block 14 locks the dustproof frame 6 on the inner side of the assembly frame 5, thereby realizing the connection and fixation between the assembly frame 5 and the dustproof frame 6.

[0040] In this embodiment, if Figure 5 to Figure 6 As shown, the assembly frame 5 is provided with an active groove 15 that is adapted to the shape of the card block 14, and the outside of the card block 14 is fixedly connected with a spring piece 17 located on the inner side of the active groove 15. The active groove 15 provided in the assembly frame 5 is adapted to the shape of the card block 14, providing space for the movement of the card block 14 when it is squeezed. The spring piece 17 outside the card block 14 can be deformed when the card block 14 is squeezed, so as to adapt to the movement of the card block 14. At the same time, when the card block 14 is not subjected to external force, the spring piece 17 can squeeze and limit the card block 14 through its own elastic force, so as to maintain the clamping state between the card block 14 and the card slot 13.

[0041] In this embodiment, if Figure 7 As shown, weakened grooves 20 are provided on both inner walls and the outside of the spring sheet 17, and two groups of symmetrically distributed support sheets 19 are fixedly connected to the inside of the spring sheet 17. The spring sheet 17 is C-shaped as a whole, and the end of the spring sheet 17 is bent toward the inside of the spring sheet 17, so that the outside of the spring sheet 17 forms an arc surface in contact with the inner wall of the movable groove 15, and can contact and slide between the movable groove 15 during the deformation of the spring sheet 17. The weakened groove 20 on the spring sheet 17 can facilitate the spring sheet 17 to deform toward the inner middle part of the spring sheet 17 when it is squeezed, guide the deformation of the spring sheet 17, and ensure the deformation posture of the spring sheet 17. When the spring sheet 17 is deformed, the end of the support sheet 19 adheres to and slides against the inner wall of the spring sheet 17, supporting the overall structure of the spring sheet 17 to prevent the spring sheet 17 from being excessively deformed and unable to recover.

[0042] In this embodiment, if Figures 4 to 5 As shown, the outside of the block 14 is fixedly connected with a pull rod 18, and the outside of the assembly frame 5 is provided with a hidden groove 16 for accommodating the pull rod 18. The pull rod 18 passes through the movable groove 15 and the hidden groove 16. Pulling the pull rod 18 can drive the block 14 to slide on the inner side of the movable groove 15, so that the staff can adjust the position of the block 14 on the outside of the assembly frame 5. The hidden groove 16 on the outside of the assembly frame 5 can accommodate the hidden pull rod 18. When the block 14 and the slot 13 are in a clamping state, the pull rod 18 is located on the inner side of the hidden groove 16, so that the overall external structure of the assembly frame 5 is smoother.

[0043] In this embodiment, if Figure 6 and Figure 8 As shown, the end of the block 14 is provided with an arcuate surface, and the outside of the dustproof frame 6 is provided with a guide groove 21 adapted to the length value of the block 14. The guide groove 21 provided on the outside of the dustproof frame 6 creates an inclined surface at this location on the outside of the dustproof frame 6, which can facilitate the positioning of the dustproof frame 6 and the block 14 during installation, and can also cooperate with the arcuate surface at the end of the block 14 so that the block 14 slides along the angle formed by the inclined surface formed by the guide groove 21, and the sliding of the block 14 is facilitated along the guidance of the inclined surface, thereby reducing the resistance during the insertion of the dustproof frame 6 and facilitating the insertion and fixation of the dustproof frame 6 to the inner side of the assembly frame 5.

[0044] Working steps

[0045] Step 1. The cooling fan 12 starts working and generates a wind beam after being powered on, and cooperates with the air vent 3 on the outside of the high-voltage distribution cabinet body 1 to generate airflow in the high-voltage distribution cabinet body 1, so as to bring out the high-temperature air in the high-voltage distribution cabinet body 1 and adjust the ambient temperature of the equipment in the high-voltage distribution cabinet body 1. When the dustproof guard plate 11 needs to be simply cleaned, directly wipe the dustproof guard plate 11 located on the outside of the cabinet door 2. When the dustproof guard plate 11 located on the inside of the cabinet door 2 needs to be cleaned, start the servo motor 7. The servo motor 7 drives the assembly frame 5 as a whole to flip over under the action of the rotating rod 10 through its drive shaft. After the assembly frame 5 is flipped, the cabinet door 2 originally located on the inside of the cabinet door 2 flips to the outside of the high-voltage distribution cabinet body 1, and can be simply cleaned by wiping it directly.

[0046] Step 2. When deep cleaning is required, pulling the pull rod 18 can drive the block 14 to retract into the movable groove 15, so that the block 14 withdraws from the groove 13, releases the lock on the dustproof frame 6, and directly pulls the dustproof frame 6 and the dustproof guard plate 11 out of the assembly frame 5 as a whole. After cleaning the dustproof frame 6 and the dustproof guard plate 11, directly align the area where the guide groove 21 is set on the dustproof frame 6 with the area where the block 14 is set in the assembly frame 5, and press it into the assembly frame 5. The block 14 can retract into the movable groove 15 after being squeezed, and at the same time compress the spring piece 17. After the position of the block 14 corresponds to the position of the groove 13, the spring piece 17 drives the block 14 to reset under the action of its own elastic force, thereby realizing the clamping connection between the block 14 and the groove 13, and fixing and stabilizing the dustproof frame 6 in the assembly frame 5.

[0047] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
