Description

Technical Field

[0001] The present application relates to the field of power distribution cabinets, and in particular to a shock-absorbing and collision-proof power distribution cabinet. Background Art

[0002] A distribution cabinet, also known as a distribution box, is divided into power distribution cabinets, lighting distribution cabinets, and metering cabinets. It is the final stage of the power distribution system. Distribution cabinets are used in situations where loads are dispersed and circuits are few. They are widely used in shopping malls, residential buildings, and highways.

[0003] At present, distribution cabinets on roads are usually installed on both sides of the road or on crosswalks. In order to reduce the possibility of safety accidents caused by leakage or collision, anti-collision barriers are usually installed around the distribution cabinets to reduce the safety hazards of the distribution cabinets being damaged or caused by line failures.

[0004] Regarding the above-mentioned related technologies, although the installation of a crash barrier can effectively reduce the possibility of the distribution cabinet being damaged, if the vehicle is driving too fast, it is easy to cause injury to the driver or passengers, damage to the crash barrier, and thus damage to the distribution cabinet. Summary of the Invention

[0005] In order to reduce the possibility of the distribution cabinet being damaged, the present application provides a shock-absorbing and collision-proof distribution cabinet.

[0006] The present application provides a shock-absorbing and collision-resistant power distribution cabinet adopting the following technical solutions:

[0007] A shock-absorbing and collision-proof distribution cabinet includes a base and a cabinet body installed on the base, wherein two sliding blocks are provided on the base, and a buffer plate connecting the two sliding blocks is provided on the sliding block. The buffer plate is an arc-shaped elastic plate and protrudes outward toward the side away from the cabinet body, and the cabinet body is located between the two buffer plates and the two sliding blocks.

[0008] By adopting the above technical solution, when a car or electric vehicle drives towards the distribution cabinet, the electric vehicle or car contacts the buffer plate, causing the buffer plate to deform in the direction close to the distribution cabinet. In this process, the elastic deformation of the buffer plate has a certain deceleration effect on the moving car or electric vehicle until the car or electric vehicle stops, reducing the possibility of damage to the distribution cabinet and, to a certain extent, reducing the possibility of injury to the driver and passengers. At the same time, the two buffer plates influence each other, which is used to increase the difficulty of the buffer plate deformation and reduce the possibility of the buffer plate being damaged.

[0009] Optionally, a sliding groove with a "T"-shaped cross-section is provided on the base, the sliding block has a "T"-shaped cross-section and is slidably arranged in the corresponding sliding groove, and a sliding spring is fixed in the sliding groove to push the two sliding blocks to move toward each other.

[0010] By adopting the above technical solution, when a motor vehicle or non-motor vehicle collides with the cabinet, it first contacts the buffer plate, and the sliding block moves in the direction away from each other in the sliding groove. Under the action of the sliding spring, it plays a certain buffering role, and the buffer plate produces a certain deformation, which plays a certain buffering role and is used to reduce the vehicle speed. At the same time, the buffer plate itself can be deformed in the direction close to the cabinet, which plays a secondary buffering role and reduces the possibility of the cabinet being damaged.

[0011] Optionally, the buffer plate is provided with a plurality of mutually parallel through grooves along the height direction, and a plurality of mutually parallel and vertically arranged guide rollers are rotatably connected in the through grooves.

[0012] By adopting the above technical solution, the setting of the guide roller has a certain buffering effect on the one hand, and on the other hand, it plays a certain guiding role for the colliding motor vehicle or non-motor vehicle, which is used to change the driving direction of the vehicle and reduce the possibility of the driver or passenger being injured by colliding with hard objects.

[0013] Optionally, a mounting groove is provided on the bottom wall of the through groove, a mounting shaft is slidably provided in the mounting groove, a connecting spring is fixed to the bottom of the mounting groove to connect the mounting shaft and push the mounting shaft to move upward, a rotating groove connected to the through groove is provided on the upper end surface of the buffer plate, a rotating shaft coaxial with the mounting shaft is threadedly connected in the rotating groove, and connecting grooves for clamping the corresponding mounting shaft and the rotating shaft are provided at both ends of the guide roller.

[0014] By adopting the above technical solution, during the installation of the guide roller, the staff can press the installation shaft to accommodate it in the installation groove, which is convenient for the guide roller to be installed in the rotating groove. The installation shaft is clamped in one of the connecting grooves to achieve the preliminary installation of the guide roller, which is convenient for the positioning of the guide roller. Then, the rotating shaft is threaded into the rotating groove, and the rotating shaft is clamped in the other connecting groove, which facilitates the installation and disassembly of the guide roller.

[0015] Optionally, the mounting shaft and the guide roller are eccentrically arranged, and an elastic plate connecting the two sliding blocks is provided on the sliding block. The elastic plate is pressed against the side wall away from the cabinet body against several guide rollers on the same buffer plate and causes the guide rollers to protrude toward the side away from the cabinet body.

[0016] By adopting the above technical solution, the setting of the elastic plate makes the guide roller bulge outward toward the side away from the cabinet body. When the vehicle is equipped with the buffer plate, since the mounting shaft and the guide roller are eccentrically arranged and bulge toward the side away from the cabinet body, the vehicle collides with the guide roller, and the guide roller rotates. Under the action of the elastic plate, the guide roller becomes increasingly difficult to rotate, so that the vehicle moves toward the tangential direction of the contact point between the guide roller and the vehicle, which facilitates changing the direction of the vehicle's movement, thereby reducing the possibility of the cabinet being hit.

[0017] Optionally, a motion groove is provided on the upper surface of the base, and the motion groove is perpendicular to the line connecting the two sliding grooves. A motion plate that is slidably set in the motion groove is fixed to the bottom of the cabinet, and a driving component is provided on the base to push the motion plate toward the buffer plate away from the hit side.

[0018] By adopting the above technical solution, when a vehicle collides with the buffer plate and the elastic plate, the driving assembly causes the cabinet to move away from the vehicle to avoid it, thereby further reducing the possibility of damage to the cabinet.

[0019] Optionally, driving grooves connected to the moving groove are opened at both ends of the moving groove in the length direction, and a pushing block is slidably arranged in the driving groove, and the pushing block abuts against the moving plate and drives the moving plate to move. The pushing block is connected to a driving block protruding from the base, and the driving block is arranged in an arc shape opposite to the side wall of the corresponding buffer plate.

[0020] By adopting the above technical solution, the buffer plate is deformed and pushes the driving block to drive the pushing block to move, so that the pushing block pushes the moving plate to move in a direction away from the vehicle, thereby reducing the possibility of the vehicle colliding with the cabinet.

[0021] Optionally, an abutment groove is provided on the base between the cabinet body and the driving block, an abutment plate is slidably provided in the abutment groove, an abutment slope is provided on the pushing block, and the abutment plate moves upward when the pushing block pushes the cabinet body to move.

[0022] By adopting the above technical solution, the elastic plate pushes the driving block to move. During the movement, the driving block pushes the abutment plate upward under the action of the abutment slope, and makes the abutment plate abut against the driving block, preventing the driving block from continuing to move and reducing the possibility of damage to the cabinet.

[0023] In summary, this application includes at least one of the following beneficial technical effects:

[0024] 1. When a vehicle approaches the distribution cabinet, it acts on the buffer plate, which, under the action of the sliding spring, slows the vehicle down. The buffer plate then deforms toward the distribution cabinet. During this process, the elastic deformation of the buffer plate acts as a secondary deceleration for the vehicle, reducing the possibility of damage to the distribution cabinet and, to a certain extent, minimizing the possibility of injury to the driver and passengers.

[0025] 2. The guide roller is eccentric to the mounting shaft, and the elastic plate makes it increasingly difficult for the guide roller to rotate, forcing the vehicle to move tangentially to the contact point with the guide roller, reducing the possibility of colliding with the distribution cabinet.

[0026] 3. A connecting groove is opened on the guide end, and it is connected by the installation shaft and the rotating shaft, which is convenient for the installation and disassembly of the guide roller. BRIEF DESCRIPTION OF THE DRAWINGS

[0034] The following is combined with Figure 1-5 This application is further described in detail.

[0035] The embodiment of the present application discloses a shock-absorbing and collision-proof distribution cabinet. Figure 1 The cabinet 2 comprises a base 1 fixed to the ground and arranged horizontally, and a cabinet 2 mounted on the upper surface of the base 1. The upper surface of the base 1 is provided with two sliding grooves 3, which are located on the same straight line and whose length is parallel to the length of the base 1. A sliding block 4 is slidably arranged in the sliding groove 3. The sliding block 4 and the sliding groove 3 have a "T"-shaped cross-section. The sliding block 4 is in contact with the inner wall of the sliding groove 3 and can slide along the length of the sliding groove 3. A horizontal sliding spring 5 is fixed in the sliding groove 3. One end of the sliding spring 5 is fixed to the inner wall of the sliding groove 3 and the other end is fixed to the sliding block 4, which pushes the two sliding blocks 4 toward each other. The sliding block 4 is provided with two buffer plates 6 connecting the two sliding blocks 4. The ends of the buffer plates 6 are rotatably connected to the sliding blocks 4 by a rotating shaft. The buffer plates 6 are curved elastic steel plates. The cabinet 2 is located between the two buffer plates 6 and the two sliding blocks 4. The buffer plates 6 protrude toward the side away from the cabinet 2, and the projection of the buffer plates 6 on the horizontal plane protrudes from the base 1.

[0036] When a vehicle approaches the cabinet 2 , it first contacts the buffer plate 6 , which then moves toward the cabinet 2 . The buffer plate 6 elastically deforms, slowing down the vehicle and reducing the possibility of damage to the cabinet 2 .

[0037] Reference Figure 2 and Figure 3 The buffer plate 6 has a plurality of through slots 7 formed along its height. The through slots 7 are parallel to each other and extend horizontally through the buffer plate 6. A plurality of guide rollers 8 are rotatably connected to the through slots 7. A mounting slot 9 is formed on the bottom wall of the through slot 7 along its height. A mounting shaft 10 is slidably disposed within the mounting slot 9. A vertically disposed connecting spring 23 is fixed to the bottom of the mounting slot 9. One end of the connecting spring 23 is fixed to the bottom wall of the mounting slot 9. The other end of the connecting spring 23 is fixed to the lower end surface of the mounting shaft 10 and pushes the upper end of the mounting shaft 10 to protrude from the bottom wall of the mounting slot 9. A rotating slot 11 communicating with the through slot 7 is formed on the upper end surface of the buffer plate 6. The rotating slot 11 is coaxial with the mounting slot 9. A rotating shaft 12 coaxial with the mounting shaft 10 is threadedly connected to the rotating slot 11. Connecting slots 13 for engaging the corresponding mounting shaft 10 and the rotating shaft 12 are formed at both ends of the guide roller 8.

[0038] Reference Figure 2 and Figure 3 The mounting shaft 10 is eccentrically arranged with the guide roller 8. The sliding block 4 is connected to an elastic plate 14 through a rotating shaft. The elastic plate 14 is an elastic steel plate and is connected to the two sliding blocks 4. In the natural state, the elastic plate 14 has the same bending degree as the buffer plate 6. The two elastic plates 14 are located between the two buffer plates 6. The side wall of the elastic plate 14 facing away from the cabinet 2 is pressed against several guide rollers 8 on the same buffer plate 6. Since the guide roller 8 is eccentrically arranged with the mounting shaft 10, the guide roller 8 protrudes toward the side facing away from the cabinet 2.

[0039] When the vehicle hits the buffer plate 6, the vehicle first contacts the guide roller 8 and pushes the guide roller 8 to rotate. During the rotation process, under the action of the elastic plate 14, the guide roller 8 becomes increasingly difficult to rotate, thereby causing the vehicle to move in the tangential direction of the contact part between the vehicle and the guide roller 8, reducing the possibility of the vehicle directly hitting the cabinet 2.

[0040] Reference Figure 2 、 4 and Figure 5A motion groove 15 is provided on the upper surface of the base 1, and the length direction of the motion groove 15 is perpendicular to the connecting line of the two sliding grooves 3. Two motion plates 16 that are slidably arranged in the motion groove 15 are fixed to the bottom of the cabinet 2. The opposite side walls of the two motion plates 16 abut against the inner walls on both sides of the width direction of the motion groove 15. A driving component is provided on the base 1 to push the motion plate 16 to move toward the buffer plate 6 away from the hit side. At both ends of the motion groove 15 in the length direction, there are driving grooves 17 connected to the motion groove 15, and a pushing block 18 is slidably arranged in the driving groove 17. The pushing block 18 abuts against the motion plate 16 and drives the motion plate 16 to move. A driving block 19 is fixed on the pushing block 18. The driving block 19 protrudes from the upper end surface of the base 1 and the projection of the driving block 19 on the ground protrudes outside the base 1. The driving block 19 is arranged in an arc shape opposite to the side wall of the corresponding elastic plate 14. No matter from which direction the vehicle hits the buffer plate 6, the elastic plate 14 will be deformed and contacted with the driving block 19, which can make the elastic plate 14 push the driving block 19 to move, so that the pushing block 18 pushes the cabinet 2 to move in the direction away from the vehicle.

[0041] Reference Figure 4 and Figure 5 Guide grooves 24 are provided on the upper surface of the base 1 on both sides of the motion groove 15. The length direction of the guide groove 24 is parallel to the length direction of the driving groove 17. A guide block 25 is fixed to the lower end surface of the cabinet 2 and is slidably arranged in the guide groove 24. The cross-sections of the guide groove 24 and the guide block 25 are both "T"-shaped and the guide block 25 is in contact with the inner wall of the guide groove 24.

[0042] Reference Figure 4 and Figure 5 An abutment groove 20 is provided on the base 1 between the cabinet 2 and the driving block 19. The length direction of the abutment groove 20 is parallel to the connecting line of the two sliding grooves 3. An abutment plate 21 that moves in the vertical direction is slidingly provided in the abutment groove 20. An abutment slope 22 is provided on the pushing block 18. The abutment slope 22 abuts against the lower end surface of the abutment plate 21. When the pushing block 18 pushes the cabinet 2 to move, under the action of the abutment slope 22, the pushing plate moves upward until it abuts against the driving block 19, which plays a positioning role on the driving block 19, preventing the driving block 19 from driving the pushing block 18 to move, thereby stopping the vehicle.

[0043] The implementation principle of a shock-absorbing and anti-collision distribution cabinet in an embodiment of the present application is as follows: when a vehicle hits the buffer plate 6, the two sliding blocks 4 move in a direction away from each other, playing a certain buffering role, which is used to reduce the vehicle speed. The buffer plate 6 and the elastic plate 14 produce elastic deformation, which plays a further buffering role, which is used to reduce the vehicle speed and reduce the possibility of the cabinet body 2 being hit and the driver or passengers being injured.

[0044] The above are all preferred embodiments of the present application, and are not intended to limit the scope of protection of the present application. Therefore, any equivalent changes made based on the structure, shape, and principle of the present application should be included in the scope of protection of the present application.
