Description

Technical Field

[0001] This invention relates to the field of low-voltage switchgear cabinet technology, specifically a miniaturized mobile low-voltage switchgear cabinet. Background Technology

[0002] Low-voltage switchgear is used for power transmission, distribution and energy conversion. The working environment is relatively complex. Good waterproof, dustproof and heat dissipation effects are related to the performance and service life of the equipment inside the low-voltage switchgear. The switchgear on the market is relatively large and inconvenient to move. For ease of use, there is an urgent need for a miniaturized mobile low-voltage switchgear cabinet.

[0003] In the prior art, Chinese Patent No. CN207218089U discloses a low-voltage switchgear, including a cabinet and a top cover on the top of the cabinet. The top cover includes a heat outlet section with heat outlet holes. The low-voltage switchgear also includes a protective device above the heat outlet section. The protective device includes a top cover with a first heat outlet cavity having a bottom opening, an extension component including a second heat outlet cavity with one end extending into the first heat outlet cavity and the other end located at the outer edge of the heat outlet section, and a support component with both ends connected to the top cover and the extension component respectively. The heat outlet holes, the second heat outlet cavity, the first heat outlet cavity, and the opening are sequentially connected. In this way, heat can diffuse outward through the heat outlet holes, the second heat outlet cavity, the first heat outlet cavity, and then through the opening. At the same time, the top end of the extension component extends into the interior of the first heat outlet cavity, and is spaced apart and connected to the top cover by the support component.

[0004] When the above-mentioned product is used in a low-voltage switchgear device, the heat outlet hole, the second heat outlet cavity, the first heat outlet cavity, and the opening are connected in sequence to ensure that the low-voltage switchgear is not threatened by rainwater and improve the waterproof and heat dissipation performance of the low-voltage switchgear. Although the switchgear can be well protected from rainwater and dissipate heat, it is inconvenient to move due to its large size. A special trolley is required to pull the switchgear, which is time-consuming and laborious.

[0005] In the prior art, Chinese Patent No. CN210608130U discloses a low-voltage switchgear, including a cabinet. The cabinet includes a busbar compartment located at the top of the cabinet. Below the busbar compartment are a circuit breaker compartment located at the front of the switchgear and a cable compartment located at the rear of the switchgear. The circuit breaker compartment and the cable compartment are adjacent to each other. A channel barrier is provided in the cable compartment. The partition between the circuit breaker compartment and the cable compartment and the channel barrier form a vertical busbar channel. A vertical busbar is installed in the vertical busbar channel. Upper and lower insulating sealing plates are installed on the upper and lower end faces of the vertical busbar channel. There is a rear air inlet below the cable compartment. A first heat dissipation hole is provided on the upper insulating sealing plate, and a second heat dissipation hole is provided on the lower insulating sealing plate. Air flows into the lower part of the cable compartment from the rear air inlet, enters the vertical busbar channel through the second heat dissipation hole of the lower insulating sealing plate and flows upward. It then flows into the busbar compartment above the switchgear through the first heat dissipation hole of the upper insulating sealing plate and finally exits to the outside of the cabinet.

[0006] When the above-mentioned products are used in low-voltage switchgear, the low-voltage switchgear has a rear air inlet below the cable compartment, a first heat dissipation hole on the upper insulating cover plate, and a second heat dissipation hole on the lower insulating cover plate, thereby increasing airflow and improving heat dissipation. However, during the heat dissipation process, dust in the air will be adsorbed on the heat dissipation clips. If not cleaned for a long time, it will block the heat dissipation holes and affect the heat dissipation efficiency. The switchgear cannot automatically clean the dust and collect the cleaned dust, requiring the user to handle it from time to time, which is time-consuming and laborious.

[0007] To address the aforementioned issues, innovative design is urgently needed based on the existing low-voltage switchgear structure. Summary of the Invention

[0008] The purpose of this invention is to provide a miniaturized mobile low-voltage switchgear cabinet to solve the problems mentioned in the background art, such as inconvenience in moving it, inability to clean dust from the heat dissipation vents, and inability to collect the cleaned dust.

[0009] The purpose of this invention is to provide a miniaturized mobile low-voltage switchgear cabinet, including a switchgear body, a cabinet door, a telescopic rod, a motor, a cooling fan, and a collection box.

Electronic components are provided at the upper inside of the switch cabinet body.

[0011] The back of the switch cabinet body is provided with a square groove, and the surface of the square groove is provided with a first heat dissipation vent. A second rotating rod is connected through the upper end of the square groove, and a second bevel gear is fixedly connected to the left end of the second rotating rod. A third bevel gear is fixedly connected to the other end of the second rotating rod. A reciprocating screw is provided at the right end of the square groove, and a fourth bevel gear is fixedly connected to the upper end of the reciprocating screw. A brush strip is threaded to the upper end of the reciprocating screw, and a sliding rod is slidably connected to the other end of the brush strip. The sliding rod is fixedly installed at the left end of the square groove.

[0012] A second heat dissipation vent is provided on the lower front side of the switch cabinet body, and a sliding groove is provided on the lower back side of the switch cabinet body. The sliding groove is located below the square groove, and a sliding block is slidably connected inside the sliding groove. A collection box is fixedly connected to the other end of the sliding block. A handle is provided on the front surface of the collection box, and a switch handle is provided on the right side of the cabinet door.

[0013] Furthermore, the collection box is rectangular when viewed from above, and two sliding blocks are provided on the collection box. The collection box forms a sliding structure through the sliding blocks and sliding grooves, and the collection box can collect dust.

[0014] Furthermore, the first heat dissipation vent is located on the rear side of the switch cabinet body, and the second heat dissipation vent is located on the front side of the switch cabinet body. The first heat dissipation vent and the second heat dissipation vent are symmetrical to each other and are used for heat dissipation.

[0015] Furthermore, the first rotating rod forms a rotating structure with the switch cabinet body via the motor, and the first bevel gear forms a rotating structure with the switch cabinet body via the first rotating rod, and the rack forms a rotating structure with the switch cabinet body via the first rotating rod, thereby enabling the moving roller to rotate.

[0016] Furthermore, the connecting rod rotates synchronously with the rack via a belt, and the moving roller forms a rotating structure with the switch cabinet body via a belt, facilitating user movement.

[0017] Furthermore, the first bevel gear meshes with the second bevel gear, and the third bevel gear meshes with the fourth bevel gear. The brush strip meshes with the reciprocating screw, and the brush strip can clean dust.

[0018] Furthermore, the switch cabinet body is circular when viewed from above, and the telescopic rod and the switch cabinet body form a telescopic structure. The telescopic rod is made of stainless steel, and the telescopic rod makes it convenient for users to move the switch cabinet.

[0019] Furthermore, the brush strip and the sliding rod form a sliding structure, and the brush strip is in close contact with the surface of the first heat dissipation vent, thereby cleaning the dust more thoroughly.

[0020] Furthermore, the protective back pad is orthogonally elliptical, and its surface is made of cowhide leather stitched together, with sponge filling inside to protect the user's back.

[0021] Compared with the prior art, the beneficial effects of the present invention are:

[0022] 1. This miniaturized mobile low-voltage switchgear cabinet has three wheels at the bottom of the cabinet body. During normal use, the three wheels support the cabinet off the ground. When the cabinet needs to be moved, the user pulls out the telescopic rod, grips the handle, and tilts the cabinet at a certain angle. The motor rotates, driving the wheels. The user simply needs to control the angle, and the cabinet will move automatically without applying any pushing or pulling force. Moving it requires minimal effort, saving time and energy. In situations with poor road conditions, the user can carry the cabinet on their shoulder using the shoulder straps until the road is clear, at which point it can be placed on the ground. The cabinet's small size allows for easy carrying by a single person, eliminating concerns about arm fatigue during prolonged movement and ensuring convenient mobility.

[0023] 2. This miniaturized mobile low-voltage switchgear cabinet dissipates heat through its vents during operation. After a period of time, dust accumulates on the surface of these vents. When the user moves the switchgear, the motor rotates, causing the brush strips to move up and down. During this movement, the dust on the surface of the first vent is brushed off. This allows the switchgear to clean its vents automatically during movement. By the time it reaches its destination, the first vent will already be clean, improving the heat dissipation efficiency of the cabinet during subsequent use and achieving the desired dust removal effect.

[0024] 3. This miniaturized mobile low-voltage switchgear cabinet is equipped with a dust collection device. During the process of the brush strip cleaning the dust from the first heat dissipation vent, the dust will fall downwards. A pull-out collection box is set below the square groove. The collection box collects the dust. When the user observes that the dust in the collection box is almost full, he / she can simply squeeze the handle to pull out the collection box for cleaning. The operation is convenient. Attached Figure Description

The telescopic rod 5 is made of stainless steel, and the protective back pad 7 is elliptical when viewed from above. The surface of the protective back pad 7 is made of cowhide leather and its interior is filled with sponge.

[0040] according to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 6 First, the user places the low-voltage switchgear cabinet on the ground. The bottom of the switchgear body 1 is equipped with front wheels 6 and moving rollers 2. These wheels support the switchgear body 1 off the ground, preventing moisture from the ground from entering the cabinet. When the user needs to move the switchgear, they pull out the telescopic rod 5 from the top of the switchgear body 1, then hold the handle 32 and tilt the switchgear. At this point, the front wheels 6 are off the ground. Then, the motor 10 is started. When the motor 10 rotates, it drives the first rotating rod 11 to rotate, thereby rotating the rack 13. When the rack 13 rotates, it drives the belt... The rotation of belt 14 causes the connecting rod 15 to rotate, which in turn drives the moving roller 2 to rotate. The moving roller 2 can rotate on its own under the action of motor 10, without the user needing to push or pull the switch cabinet. Only the direction needs to be controlled, saving time and effort. The switch cabinet can be moved by an individual, which is simple and convenient. When encountering poor road conditions, the user can carry the switch cabinet on their shoulder using the shoulder strap 9 until the road conditions are good, at which point it can be placed on the ground. The user does not need to worry about arm fatigue from moving for a long time, achieving the effect of convenient movement.

[0041] The collection box 29 is rectangular when viewed from above, and two sliding blocks 28 are provided on the collection box 29. The collection box 29 forms a sliding structure with the sliding block 28 and the sliding groove 27. The first rotating rod 11 forms a rotating structure with the switch cabinet body 1 through the motor 10. The first bevel gear 12 forms a rotating structure with the switch cabinet body 1 through the first rotating rod 11. The rack 13 forms a rotating structure with the switch cabinet body 1 through the first rotating rod 11. The first bevel gear 12 is meshed with the second bevel gear 18. The third bevel gear 20 is meshed with the fourth bevel gear 21. The brush strip 23 is meshed with the reciprocating screw 22. The brush strip 23 forms a sliding structure with the sliding rod 24. The brush strip 23 is in close contact with the surface of the first heat dissipation port 25.

[0042] according to Figures 1-8 The switch cabinet body 1 is equipped with a cooling fan 16. The cooling fan 16 has a second heat dissipation vent 26 and a first heat dissipation vent 25 symmetrically arranged at its front and rear. The second heat dissipation vent 26 dissipates air, while the first heat dissipation vent 25 draws in air. During the air intake process, external dust is adsorbed onto the surface of the first heat dissipation vent 25. When the user moves the switch cabinet, the first rotating rod 11 rotates, which drives the first bevel gear 12 to rotate, thereby causing the second bevel gear 18 to rotate. The rotation of the second bevel gear 18 drives the third bevel gear 20 to rotate, thereby causing the fourth bevel gear 21 to rotate, thus causing the reciprocating screw 2... 2. When the reciprocating screw 22 rotates, it causes the brush strip 23 to move up and down, brushing and cleaning the surface of the first heat dissipation vent 25. The cleaned dust will fall into the collection box 29, which collects the dust. When the user observes that the collection box 29 is almost full of dust, he / she can simply squeeze the handle 30 to pull out the collection box 29 for cleaning. The operation is convenient and achieves the effect of collecting dust. The switch cabinet removes dust from the first heat dissipation vent 25 during the movement process, which improves the heat dissipation efficiency of the heat dissipation cabinet when it is used later, and achieves the effect of cleaning the dust from the first heat dissipation vent 25.
