Description

Technical Field

[0001] This utility model relates to an anti-seismic protection structure for high and low voltage distribution cabinets, belonging to the technical field of anti-seismic protection structure. Background Technology

[0002] Distribution cabinets (boxes) are divided into power distribution cabinets (boxes), lighting distribution cabinets (boxes), and metering cabinets (boxes). They are the final-level equipment in a power distribution system. Distribution cabinets are a general term for motor control centers. Distribution cabinets are used in situations where the load is relatively dispersed and there are fewer circuits; motor control centers are used in situations where the load is concentrated and there are more circuits. They distribute the electrical energy of a circuit in the previous-level power distribution equipment to the nearest load. This level of equipment should provide protection, monitoring, and control for the load.

[0003] Chinese Patent Publication No. CN 209419039 U discloses a power distribution cabinet. It mainly solves the problem that ventilation windows on current power distribution cabinets cannot be removed after prolonged use, making it difficult to clean dust or other blockages. The cabinet is characterized by: a plurality of ventilation windows on the ventilation plate; an opening groove on the cabinet body; an upper and lower edge on the inner wall of the cabinet door opposite the opening groove; a top plate and a bottom plate on the inner wall of the ventilation plate in a horizontal direction; the top plate is detachably connected to the upper edge; the bottom plate is detachably connected to the lower edge; and the ventilation plate covers the opening groove. This utility model provides a power distribution cabinet, including a cabinet body, whose ventilation plate can be removed separately for easy cleaning.

[0004] When using a power distribution cabinet, it is usually assembled and transported to the site. However, during transportation, the cabinet may vibrate due to road bumps. The vibrations may affect the wiring inside the cabinet, causing the screws to loosen and the wires to come loose. This can lead to a break in the wiring inside the cabinet, affecting its normal operation.

[0005] Therefore, a seismic protection structure for high and low voltage distribution cabinets is proposed. Summary of the Invention

[0006] In view of this, the present invention provides a high and low voltage distribution cabinet anti-vibration protection structure to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0007] The technical solution of this utility model is implemented as follows: A high and low voltage distribution cabinet anti-vibration protection structure includes a distribution cabinet body, characterized in that a box is provided at the bottom of the distribution cabinet body, ventilation slots are provided on both the left and right sides of the distribution cabinet body, and an anti-vibration mechanism is provided on the surface of the box body. The anti-vibration mechanism includes an arc-shaped block, a frame, and a spring damper. The arc-shaped block is located in the inner cavity of the box body, and the surface of the arc-shaped block is in contact with the bottom of the distribution cabinet body. Two frames are fixedly installed on the front and rear sides of the box body, and sliding rods are fixedly installed on the inner sides of the two frames. Toothed plates are slidably connected to the left and right sides of the surfaces of the two sliding rods, and damping springs are fixedly connected to the inner sides of the four toothed plates.

[0008] More preferably, connecting rods are movably connected to both the left and right sides of the inner cavity of the box, the arc-shaped blocks are fixedly installed on the surfaces of the two connecting rods, gears are fixedly connected to both the front and rear sides of the two connecting rods, and the surfaces of the four frames mesh with the surfaces of the four toothed plates.

[0009] More preferably, the four spring dampers are all fixedly installed on the left and right sides of the bottom of the box cavity, and the tops of the four spring dampers are all fixedly installed on the left and right sides of the bottom of the distribution cabinet.

[0010] More preferably, the top of both frames is provided with a sliding groove, and the top of the four toothed plates passes through the inner cavity of the two sliding grooves and extends to the top of the two frames.

[0011] More preferably, the left and right sides of the inner cavity of the box are provided with movable slots, and the left and right sides of the power distribution cabinet are slidably connected to the inner cavities of the two movable slots.

[0012] More preferably, filters are provided on both the left and right sides of the power distribution cabinet, and both filters are at the same horizontal level as the two ventilation slots.

[0013] More preferably, both of the filter screens are threaded with mounting bolts, and the inner threads of the mounting bolts are connected to the inner surface of the power distribution cabinet.

[0014] More preferably, a base plate is fixedly installed on both the left and right sides of the box body, and the top of each of the four base plates is threaded with anchor bolts.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model incorporates an anti-vibration mechanism. When the distribution cabinet encounters bumpy road conditions and sways up and down, the arc-shaped block rotates circumferentially due to the downward pressure. At this time, the gear drives the frame to move inward, compressing the damping spring. Simultaneously, as the distribution cabinet is pressed down, the spring damper is compressed and deforms. The spring damper and damping spring dampen and buffer the force of the distribution cabinet's up and down swaying, thereby achieving shock absorption of the distribution cabinet. This effectively prevents damage to the distribution cabinet due to bumps during transportation, ensuring the safety of the distribution cabinet during transportation, improving the shock resistance effect during transportation, and facilitating subsequent normal use.

[0017] II. This utility model, by setting a sliding groove, can limit the movement of the toothed plate, preventing changes in the direction of the toothed plate during movement, thus affecting the seismic protection of the power distribution cabinet. By setting a moving groove, the direction of the power distribution cabinet's up-and-down swaying can be limited, preventing deviation during movement, thus affecting the cushioning effect of the seismic mechanism on the power distribution cabinet. By setting a filter screen, the ventilation slot can be filtered, preventing dust from entering the internal cavity of the power distribution cabinet through the ventilation slot, thus preventing damage to the internal components due to dust. By setting mounting bolts, the filter screen can be easily disassembled, preventing excessive dust accumulation on the filter screen after long-term use, which would reduce the filter's filtration effect. By setting anchor bolts, the overall equipment can be stabilized, facilitating the later fixing of the entire equipment in the designated placement position.

[0018] The above overview is for illustrative purposes only and is not intended to be limiting in any way. In addition to the illustrative aspects, embodiments, and features described above, further aspects, embodiments, and features of the present invention will become readily apparent from the accompanying drawings and the following detailed description.

[0026] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0027] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings. Example 1

[0028] like Figure 1-5As shown, this utility model embodiment provides a high and low voltage distribution cabinet anti-vibration protection structure, including a distribution cabinet body 1, a box body 3 at the bottom of the distribution cabinet body 1, ventilation slots 4 on both the left and right sides of the distribution cabinet body 1, and an anti-vibration mechanism 2 on the surface of the box body 3. The anti-vibration mechanism 2 includes an arc-shaped block 202, a frame 204, and a spring damper 209. The arc-shaped block 202 is located in the inner cavity of the box body 3, and the surface of the arc-shaped block 202 is in contact with the bottom of the distribution cabinet body 1. Two frames 204 are fixedly installed on the front and rear sides of the box body 3. Slide rods 205 are fixedly installed on the inner sides of the two frames 204. Toothed plates 206 are slidably connected to the left and right sides of the surfaces of the two slide rods 205. Damping springs 207 are fixedly connected to the inner sides of the four toothed plates 206. The left and right sides of the inner cavity of the box body 3 are... Each of the two connecting rods 201 is movably connected. The arc-shaped blocks 202 are fixedly installed on the surfaces of the two connecting rods 201. Gears 203 are fixedly connected to the front and rear sides of the two connecting rods 201. The surfaces of the four frames 204 mesh with the surfaces of the four toothed plates 206. The four spring dampers 209 are fixedly installed on the left and right sides of the bottom of the inner cavity of the box 3. The tops of the four spring dampers 209 are fixedly installed on the left and right sides of the bottom of the distribution cabinet 1. The tops of the two frames 204 are provided with sliding grooves 208. The tops of the four toothed plates 206 penetrate the inner cavities of the two sliding grooves 208 and extend to the tops of the two frames 204. The left and right sides of the inner cavity of the box 3 are provided with moving grooves 210. The left and right sides of the distribution cabinet 1 are slidably connected to the inner cavities of the two moving grooves 210.

[0029] By setting up the anti-vibration mechanism 2, when the distribution cabinet 1 encounters a bumpy road section and sways up and down, the arc-shaped block 202 is subjected to downward pressure and rotates in the circumferential direction. At this time, the gear 203 drives the frame 204 to move inward, thereby compressing the damping spring 207. Simultaneously, as the distribution cabinet 1 is pressed down, the spring damper 209 is compressed and deforms. At this time, the spring damper 209 and the damping spring 207 can dampen and buffer the force of the up and down swaying of the distribution cabinet 1, thereby realizing the shock absorption of the distribution cabinet 1 and effectively preventing the distribution cabinet 1 from being damaged during transportation. To prevent damage caused by bumps, the safety of the distribution cabinet 1 during transportation is ensured, the shock resistance of the distribution cabinet 1 during transportation is improved, and subsequent normal use is facilitated. By setting the slide groove 208, the movement of the toothed plate 206 can be limited to prevent the toothed plate 206 from changing direction during movement, which would affect the shock resistance of the distribution cabinet 1. By setting the moving groove 210, the direction of the distribution cabinet 1 when it shakes up and down can be limited to prevent it from deviating during movement, which would affect the buffering work of the shock-resistant mechanism 2 on the distribution cabinet 1. Example 2

[0030] like Figure 1-4As shown, in one embodiment, filter screens 5 are provided on both the left and right sides of the power distribution cabinet 1. Both filter screens 5 are at the same horizontal level as the two ventilation slots 4. The surfaces of both filter screens 5 are threaded with mounting bolts 6. The inner side of the mounting bolts 6 is threaded to the inner surface of the power distribution cabinet 1. Base plates 7 are fixedly installed on both the left and right sides of the box 3. The tops of the four base plates 7 are threaded with anchor bolts 8.

[0031] By setting up the filter screen 5, the ventilation slot 4 can be filtered to prevent dust from entering the inner cavity of the power distribution cabinet 1 through the ventilation slot 4, which would cause damage to the internal components of the power distribution cabinet 1 due to dust. By setting up the mounting bolts 6, the filter screen 5 can be easily disassembled to prevent the filter screen 5 from being covered with too much dust after long-term use, which would reduce the filtering effect of the filter screen 5. By setting up the anchor bolts 8, the equipment can be stabilized as a whole, making it easy to fix the equipment in the correct position later.

[0032] In operation, when the distribution cabinet 1 encounters bumpy road conditions during transportation and sways up and down, the distribution cabinet 1 presses down on the arc-shaped block 202 and the spring damper 209. At this time, the arc-shaped block 202 rotates in the circumferential direction, driving the connecting rod 201 to rotate synchronously. As the connecting rod 201 rotates, the gear 203 rotates and cooperates with the toothed plate 206. At this time, the toothed plate 206 compresses the damping spring 207 inward. As the spring damper 209 and the damping spring 207 are compressed, they deform. Through the inherent characteristics of the spring damper 209 and the damping spring 207, they dampen and absorb the downward impact force generated by the distribution cabinet 1, thereby achieving the anti-vibration protection of the distribution cabinet 1.

[0033] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
