Description

Technical Field

[0001] The present invention relates to the technical field of distribution boxes, and in particular to a distribution box based on an explosion-proof buffer structure. Background Art

[0002] A distribution box is a device used in power systems for power generation, transmission, distribution, conversion, and consumption, performing switching, control, and protection functions. Typically installed in open areas, distribution boxes are susceptible to external knocks and impacts. These impacts can damage the box itself and even the electronic components within it, potentially leading to leakage and short circuits, potentially resulting in fires or explosions. This not only impacts power supply but also poses significant safety risks to maintenance personnel.

[0003] In order to improve the impact resistance of the distribution box and ensure the safe operation of the equipment, workers usually set up explosion-proof and buffer structures for the distribution box. However, the existing distribution box based on the explosion-proof buffer structure mainly relies on the elasticity of the spring to achieve buffering, and the support effect of the spring is poor. When the distribution box is subjected to a violent impact, the spring is difficult to provide effective support for the external box body of the distribution box, making the external box body prone to a large degree of deformation and the impact resistance of the box body greatly reduced, resulting in a short service life of the distribution box and poor overall explosion-proof buffering effect.

[0004] Based on the above situation, the present invention proposes a distribution box based on an explosion-proof buffer structure with good explosion-proof buffer effect. Summary of the Invention

[0005] In order to overcome the shortcomings of the existing distribution box based on the explosion-proof buffer structure, which mainly relies on the elasticity of the spring to achieve buffering, and the supporting effect of the spring is poor, when the distribution box is subjected to a violent impact, the spring is difficult to provide effective support for the external box body of the distribution box, which makes the external box body prone to a large degree of deformation and greatly reduces the impact resistance of the box body, thereby resulting in a short service life of the distribution box and poor overall explosion-proof buffering effect.

[0014] Compared with the prior art, the present invention has the following advantages: 1. The present invention uses components such as buffer frames and V-shaped hollow plates to not only form a double-layer structure and effectively disperse and absorb external force impacts with the help of isolation and support of the inner and outer layers, thereby improving the mechanical strength and impact resistance of the distribution box, but also can use elastic components to buffer when the impact is small, and use the V-shaped hollow plates and the water inside them to buffer, support and protect when the impact is large, so as to avoid serious deformation of the distribution box, thereby improving the explosion-proof buffering effect of this distribution box.

[0015] 2. The present invention uses components such as a compression tank and a top block to fill foam glue into the cavity between the box body and the buffer frame when the box body is deformed due to a strong impact. This not only reinforces the deformed part of the box body and enhances the overall structural stability of the box body, but also absorbs and disperses the impact energy with the help of the solidified foam glue during subsequent use, thereby reducing the impact of vibration on the box body and its internal components, thereby improving the explosion-proof buffering effect of this distribution box.

[0016] 3. The present invention not only provides stronger support for the opening and closing door through the installation frame and reinforcement ribs, thereby enhancing the overall structural stability of the opening and closing door, but also can effectively guide and disperse the impact force with the help of the quadrangular pyramid reinforcement frame and deviate it from the original path, thereby reducing the concentrated force points and reducing the direct impact on the main structure of the opening and closing door, thereby improving the impact resistance of the opening and closing door and enhancing the explosion-proof buffer effect of this distribution box.

[0017] 4. The present invention uses components such as insulating cutters and limit blocks to cut off power supply when components such as buffer racks are severely deformed or even cause fire due to severe impact. This not only reduces the supply of fire sources to shorten the burning time of the fire and control the spread of the fire, but also reduces the risk of electric shock during the fire extinguishing process to ensure the safety of firefighters, thereby improving the explosion-proof effect and safety of the distribution box.

[0018] 5. The present invention uses components such as gas tanks and gas valves to release carbon dioxide while cutting off the power supply, thereby effectively preventing the spread and expansion of fire and even causing an explosion, thereby reducing the damage caused by fire to the electrical equipment inside the distribution box and improving the explosion-proof effect and safety of the distribution box.

[0037] The preferred technical solutions of the present invention will be described in detail below with reference to the accompanying drawings.

[0038] Example 1

[0039] A distribution box based on explosion-proof buffer structure, such as Figures 1-6 As shown, it includes a box body 1, an opening and closing door 11, a power distribution meter 12, a liquid storage tank 13, a buffer frame 14, an impact frame 1401, an elastic component 1402, a liquid guide tube 15 and a V-shaped hollow plate 16. The front side of the box body 1 is rotatably connected to the opening and closing door 11. The upper and lower sides of the inner wall of the box body 1 are fixed with the power distribution meter 12 distributed symmetrically on the left and right sides. The buffer frame 14 is fixed inside the box body 1. The left and right sides and the upper and lower sides of the outer side of the box body 1 are slidably connected to the impact frame 1401. Four symmetrically distributed elastic components 1402 are fixed between the frame 1401 and the box body 1, two pins are slidably connected to the front side of the impact frame 1401, and the pins are slidably connected to the box body 1, and the upper and lower sides of the buffer frame 14 are fixed with liquid storage tanks 13, and the left and right sides and the upper and lower sides of the outside of the buffer frame 14 are fixed with V-shaped hollow plates 16 distributed longitudinally in the front and rear. A liquid guide tube 15 is fixed and connected between the liquid storage tank 13 and the adjacent V-shaped hollow plates 16 distributed longitudinally in the front and rear.

[0040] like Figures 1-4 As shown, line channels are opened on both the left and right sides of the lower part of the box body 1.

[0041] Before installing the distribution box, workers need to fix the impact frame 1401 on the box body 1 with a pin to prevent the impact frame 1401 from moving due to accidental touch during the installation process. After fixing, the box body 1 and other components can be wall-mounted first, and then the external wires can be passed through the line channel and connected to the distribution meter 12. After connecting the lines, the pins can be pulled out. When the upper and lower sides or the left and right sides of the distribution box are impacted by the outside world, if the impact force is small, the impact frames 1401 on all sides can effectively buffer the impact force with the help of the elastic component 1402. If the impact force is large and the impact frame 1401 and the elastic component 1402 are not enough to buffer, the external impact will drive the impact frame 1401 to move toward the distribution meter 12 and hit the surface of the box body 1, and the elastic component 1402 will be compressed immediately. At this time, the double-layer structure composed of the box body 1 and the buffer frame 14 can be supported by the isolation and support of the inner and outer layers. The support effectively disperses and absorbs external force impact, thereby improving the mechanical strength and impact resistance of the distribution box, and the longitudinally distributed V-shaped hollow plate 16 can not only buffer the impact force through its own elasticity, but also provide uniform supporting force for the box body 1, so as to reduce the deformation of the box body 1 caused by local uneven force. When the box body 1 and the V-shaped hollow plate 16 are deformed under the action of external impact, the volume of the V-shaped hollow plate 16 is reduced, and part of the water flow will flow into the upper liquid storage tank 13 along the liquid guide tube 15, so that the impact force can be evenly distributed with the help of the fluidity of water, thereby reducing local stress concentration and improving the buffering performance. If the impact force is too large and causes an external fire, the box body 1 and the V-shaped hollow plate 16 may be severely deformed or even ruptured under the action of external impact. At this time, the water in the V-shaped hollow plate 16 and the liquid storage tank 13 will flow outward and control the surrounding fire to prevent the fire from spreading or even causing an explosion.

[0042] Example 2

[0043] On the basis of Example 1, Figure 7-10 As shown, a reinforcement mechanism is also included, which is arranged on the buffer frame 14. The reinforcement mechanism includes a compression tank 2, a top block 201, a nozzle 202, a first pull rope 21, a magnetic block 22, an opening and closing valve 23 and a torsion spring 24. Eight compression tanks 2 are fixed to the four corners of the buffer frame 14 in groups of two. The compression tank 2 is fixed to and connected to the buffer frame 14 with a nozzle 202. The opening and closing valve 23 is rotatably connected to the rear side of the compression tank 2. A torsion spring 24 is fixed between the opening and closing valve 23 and the compression tank 2. The first pull rope 21 is fixed to the lower side of the opening and closing valve 23. The end of the first pull rope 21 away from the closing valve 23 is fixed to the magnetic block 22. The two adjacent magnetic blocks 22 are magnetically attracted to each other. The top block 201 is fixed to the side of the impact frame 1401 close to the adjacent magnetic block 22. The top block 201 is slidably connected to the box body 1, and the top block 201 is squeezed and fitted with the adjacent magnetic block 22.

[0044] When the impact frame 1401 and the box body 1 and other components move or deform due to a large impact force and the impact resistance is greatly reduced, the impact frame 1401 will drive the top block 201 to move in the direction close to the distribution meter 12. Since the opening and closing valve 23 is in a closed state, the torsion spring 24 is in a deformed state, and the first pull rope 21 is in a straight state, the top block 201 moves in the direction close to the distribution meter 12 until it contacts and squeezes the two magnets 22 adsorbed together. The two magnets 22 will be in the action of the top block 201 and the first pull rope 21. When the box 1 is separated from the box 1, the first pull rope 21 is loosened, and the opening and closing valve 23 is rotated and opened by the torsion spring 24. At this time, the compression tank 2 will fill the cavity between the box body 1 and the buffer frame 14 with foam glue through the nozzle 202. This not only can reinforce the deformed part of the box body 1 and enhance the overall structural stability of the box body 1 with the help of the foam glue, thereby extending the service life of the box body 1 and other components, but also can absorb and disperse the impact energy with the help of the solidified foam glue during subsequent use, so as to reduce the impact of vibration on the box body 1 and its internal components.

[0045] like Figure 11-13 As shown, an explosion-proof mechanism is also included, which is arranged on the opening and closing door 11. The explosion-proof mechanism includes a mounting frame 3, reinforcing ribs 31 and a reinforcement frame 32. The mounting frame 3 is fixed to the inside of the opening and closing door 11, and the middle part of the mounting frame 3 is fixed to the reinforcement frame 32. The side of the reinforcement frame 32 close to the box body 1 is fixed with reinforcing ribs 31 distributed longitudinally in the upper and lower directions.

[0046] like Figure 11-13 As shown, the reinforcement frame 32 is in the shape of a quadrangular pyramid.

[0047] When the front side of the distribution box is impacted by the outside world, the front side of the opening and closing door 11 will be concave inward under the action of the external impact and contact the reinforcement frame 32, thereby transmitting the impact force to the reinforcement frame 32, and the quadrangular pyramid-shaped reinforcement frame 32 can effectively guide and disperse the impact force and deviate it from the original path, thereby reducing the concentrated force points and reducing the direct impact on the main structure of the opening and closing door 11, thereby improving the impact resistance of the opening and closing door 11. The reinforcing ribs 31 distributed longitudinally in the upper and lower parts can provide stronger support for the opening and closing door 11 and the reinforcement frame 32, thereby enhancing the overall structural stability of the opening and closing door 11 and the reinforcement frame 32.

[0048] like Figure 14 and Figure 15As shown, it also includes a power-off mechanism, which is arranged in the box body 1. The power-off mechanism includes a mounting plate 4, a guide block 401, a clamping column 41, a second pull rope 42, an insulating tool 43, a spring piece 44 and a limit block 45. The two mounting plate frames 4 are respectively fixed to the left and right sides of the box body 1, and the insulating tool 43 is slidably connected inside the mounting plate frame 4. The insulating tool 43 and the mounting plate frame 4 are fixed with two left and right spring pieces 44. The front side of the insulating tool 43 is rotatably connected to the clamping column 41 through a damping ring. The clamping column 41 is in contact with the mounting plate frame 4. The sides of the two mounting plate frames 4 away from each other are both slidably connected to the limit block 45, and the limit block 45 is in contact with the insulating tool 43. The left and right sides of the buffer frame 14 are fixed with guide blocks 401. The second pull rope 42 is slidably connected inside the guide block 401. One end of the second pull rope 42 is fixed to the buffer frame 14, and the other end of the second pull rope 42 is fixed to the adjacent limit block 45.

[0049] like Figure 14 and Figure 15 As shown, an elliptical slide groove is provided in the middle of the front side of the mounting plate frame 4, and an elliptical card is fixed to the middle of the card column 41.

[0050] When the worker is about to connect the line of the power distribution meter 12, he needs to first align the card on the card post 41 with the slide groove on the mounting plate frame 4, and drive the insulating tool 43 forward through the card post 41, so that there is a gap between the insulating tool 43 and the rear side of the inner wall of the mounting plate frame 4, and the spring piece 44 is compressed. Then the card post 41 is rotated 90 degrees in the forward direction, so that the card on the card post 41 is no longer aligned with the slide groove on the mounting plate frame 4. Next, the card post 41 can be loosened and the limit block 45 can be moved in the direction close to the insulating tool 43 until the limit block 45 contacts and limits the insulating tool 43. At this time, the worker can make the external line pass through the gap between the insulating tool 43 and the mounting plate frame 4 and connect it to the power distribution meter 12. After the line connection is completed, the card post 41 is rotated 90 degrees in the opposite direction. At this time, although the card on the card post 41 is aligned with the slide groove on the mounting plate frame 4, The second pull rope 42 is used to pull the second pull rope 42 and move the limit block 45 away from the insulating cutter 43 until the limit block 45 is separated from the insulating cutter 43. At this time, the insulating cutter 43 is no longer restricted and will drive the column 41 to move backward and reset under the action of the shrapnel 44 and cut off the line on the distribution meter 12. In this way, the power supply can be cut off when the buffer rack 14 and other components are severely deformed or even cause a fire due to a severe impact. This can not only reduce the supply of fire source, shorten the burning time of the fire and control the spread of the fire, but also reduce the risk of electric shock during the fire fighting process to ensure the safety of the fire fighters.

[0051] like Figure 16 and Figure 17 As shown, a fire prevention mechanism is also included, which is arranged on the buffer frame 14. The fire prevention mechanism includes a placement frame 5, a gas tank 51, an air valve 52, a third pull rope 53, a guide pipe 54 and a pulling frame 55. The placement frame 5 is fixed to the lower part of the buffer frame 14, and the gas tank 51 is fixed to the top of the placement frame 5. The gas tank 51 is rotatably connected to the left and right sides of the gas tank 51. A pulling frame 55 is fixed between the left and right air valves 52. The front side of the mounting plate frame 4 is fixed to the guide pipe 54, and the inside of the guide pipe 54 is slidably connected to the third pull rope 53. One end of the third pull rope 53 is fixed to the adjacent insulating tool 43, and the other end of the third pull rope 53 is fixed to the pulling frame 55.

[0052] When the insulating cutter 43 moves backward and resets under the action of the spring 44, the insulating cutter 43 will drive the pulling frame 55 to rotate upward through the third pull rope 53, and the gas valve 52 will also rotate and open with the pulling frame 55. At this time, the carbon dioxide in the gas tank 51 will be released outward through the gas valve 52, and the carbon dioxide can effectively prevent the spread and expansion of the fire and even cause an explosion, thereby reducing the damage of the fire to the electrical equipment inside the distribution box.

Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention.
