Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of high-altitude power distribution cabinet, and particularly relates to a power distribution cabinet safety connection structure and a high-altitude power distribution cabinet comprising the same. BACKGROUND

[0002] During power construction, a power distribution cabinet system is often needed, and the power distribution cabinet system plays an important role in power construction. The power distribution cabinet system has developed into many structural forms, and is classified into ground use and high-altitude use. The power distribution cabinet system used on the ground is directly installed on the ground or a wall body. For the power distribution cabinet system used at high altitudes, safety is an important indicator.

[0003] The fixed device and the power distribution cabinet system with the application number CN202011270886.3 are fixedly arranged with fixed sleeve devices on two telegraph poles. The fixed sleeve devices comprise a first fixed sleeve and a second fixed sleeve. The first fixed sleeve is fixedly arranged with the box body, and the second fixed sleeve is movably arranged with the first fixed sleeve. The first fixed sleeve and the second fixed sleeve are provided with accommodating grooves capable of accommodating telegraph poles. The first fixed sleeve and the second fixed sleeve are respectively provided with through holes. The through hole of the first fixed sleeve and the through hole of the second fixed sleeve are provided with a bolt assembly, which can prevent the power distribution cabinet body from sliding off the telegraph pole.

[0004] However, in the actual use process, the high-altitude power distribution cabinet system is fixed on the telegraph pole by the way of the hoop. The existing hoop is connected by bolts. When installing, the bolts need to be tightened one by one. For telegraph poles with special shapes or sizes, the existing hoop may not fit closely, affecting the fixing effect. In strong winds and other harsh environments, the power distribution cabinet will sway, and the sway of the power distribution cabinet will directly transmit the vibration to the bolts of the hoop, causing the nuts on the hoop to loosen due to vibration, resulting in the hoop falling off the telegraph pole, which has a great safety hazard.

[0005] Therefore, the present application provides a power distribution cabinet safety connection structure and a high-altitude power distribution cabinet comprising the same to solve the above problems. SUMMARY

[0006] The present application aims to provide a power distribution cabinet safety connection structure and a high-altitude power distribution cabinet comprising the same to solve the problems raised in the background.

[0007] To achieve the above-mentioned purpose, the present application provides the following technical scheme: a power distribution cabinet safety connection structure applied to the fixed installation between a telegraph pole and a power distribution cabinet body, comprising four groups of connection units with the same structure and fixedly arranged on the telegraph pole.

The upper two groups of connection units are fixedly assembled with second connectors limitedly installed on the power distribution cabinet body.

[0008] Each clamping device includes two sets of semi-clamps hinged together by movable pins. Each set of semi-clamps has an integrally formed connecting ear. The inner sidewall of each set of semi-clamps is staggered from top to bottom with a first pressure plate, a second pressure plate, a third pressure plate, a fourth pressure plate and a fifth pressure plate arranged in an arc. The locking device is locked onto the two sets of connecting ears.

[0009] Preferably, the first connector includes two sets of parallel guide rails, each set of guide rails has a slide rail at the top, each set of slide rails has a slide seat slidably assembled in the slide rail, and a reinforcing rib is fixedly connected between the two sets of slide seats. A limiting cylinder that engages with the two sets of semi-clamps is fixed in the middle of the bottom of the reinforcing rib. The second connector has the same structural composition.

[0010] Preferably, the first connector further includes a first support seat fixed to the end of the guide rail, and a shock-absorbing air bag is fixedly provided on the top of each set of first support seats. The second connector further includes a second support seat fixed to the end of the guide rail.

[0011] Preferably, the reinforcing ribs are mounted on the top of the two sets of semi-clamps, the slide is a T-shaped slide, and each set of slides has a pressure-bearing air bag fixed on the side wall away from the power distribution cabinet, which is stored in the slide. The other end of the pressure-bearing air bag is fixed on the inner side wall of the slide. Each set of pressure-bearing air bags is connected to its corresponding shock-absorbing air bag through an air guide pipe.

[0012] Preferably, the locking device includes a bolt connecting two sets of connecting ears, a plug plate is fixedly installed at one end of the bolt, an anti-loosening air bag is sleeved on the outside of the bolt and the anti-loosening air bag is clamped between the two sets of connecting ears, and a locking nut is threaded onto the other end of the bolt.

[0013] Preferably, the connecting unit further includes a fixed pin integrally formed with the bottom end of the movable pin, and the fixed pin is inserted and installed at the bottom of the limiting cylinder. A sealing air bag is fixedly sleeved on the outer side wall of the fixed pin, and each set of sealing air bags is connected to its corresponding anti-loosening air bag through an air supply pipe.

[0014] Preferably, the first pressure plate, the second pressure plate, the third pressure plate, the fourth pressure plate and the fifth pressure plate have the same structure, and the first pressure plate includes a limiting clip that is hinged to the inner side wall of the semi-clamp through a hinge shaft, and a rubber sheet is fixed on the side wall of the limiting clip near the semi-clamp.

[0015] The present invention provides a high-altitude power distribution cabinet, including a power distribution cabinet safety connection structure, including a power distribution cabinet body, a base fixedly installed at the bottom of the power distribution cabinet body, and limiting grooves matching a first support seat on both the left and right sides of the bottom of the base. Support seats are fixedly installed on the top of the left and right side walls of the power distribution cabinet body, and the second support seat is engaged and assembled on the support seats.

[0016] Preferably, the bottom of the left and right side walls of the base and the support are provided with mounting grooves, and the size of the mounting grooves matches the guide rail. The mounting groove on the lower side is connected to the limiting groove, and the shock-absorbing air bag is stored and assembled inside the limiting groove.

[0017] Preferably, the base has locking grooves on both the front and rear side walls that correspond to the mounting grooves, and locking strips are inserted into the locking grooves. The guide rail is located on top of the locking strips, and the locking strips block and limit the guide rail.

[0018] The technical effects and advantages of this invention are as follows:

[0019] 1. This invention allows for quick and easy locking onto utility poles via the cooperation of a clamping device and a locking device. Then, the first and second connectors are assembled onto the clamping device, locking the distribution cabinet and completing its fixed installation. The locking device secures the clamping device, and the limiting cylinder is fitted onto the fixing pin, limiting the position of the first and second connectors. Gas from inside the anti-loosening air bag is introduced into the sealing air bag through the gas delivery pipe, causing the sealing air bag to expand and be sealed inside the limiting cylinder. This compresses and limits the fixing pin inside the limiting cylinder, preventing the limiting cylinder from detaching from the fixing pin and increasing the stability of the first and second connectors on the clamping device.

[0020] 2. This invention connects the locking device and the distribution cabinet through the first connector and the second connector. The distance between the first connector and the second connector and the distribution cabinet can be adjusted in real time according to the distance between the two sets of utility poles, improving the adaptability of the connection unit when the distribution cabinet is installed on the utility pole. The slide can move inside the slide rail, which facilitates the adjustment of the distance between the slide and the distribution cabinet. Moreover, when the slide moves inside the slide rail, the slide has a squeezing effect on the pressure-bearing air bag, causing the gas in the pressure-bearing air bag to be introduced into the shock-absorbing air bag through the air guide pipe, thereby causing the shock-absorbing air bag to expand and increasing the shock-absorbing air bag's impact-resistant buffer protection effect on the distribution cabinet during use.

[0030] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0031] Example 1:

[0032] like Figures 1 to 5 As shown, this embodiment discloses a safe connection structure for a power distribution cabinet, which is used for fixed installation between the utility pole 10 and the power distribution cabinet body 50. This significantly improves the convenience and stability of installing the power distribution cabinet body 50 on the utility pole 10. Specifically, it includes four sets of identical connection units that are fixedly sleeved on the utility pole 10. Two sets of connection units are installed on the top left and right sides of the power distribution cabinet body 50, and the other two sets of connection units are installed on the bottom left and right sides of the power distribution cabinet body 50, thus supporting the power distribution cabinet body 50, increasing the force points during installation, and improving installation stability.

[0033] Each set of connection units includes a clamp 20 and a locking device 60. The lower two sets of connection units are fixedly equipped with a first connector 30 that is limited and installed on the power distribution cabinet 50. The upper two sets of connection units are fixedly equipped with a second connector 40 that is limited and installed on the power distribution cabinet 50. The first connector 30 and the second connector 40 are installed on the power distribution cabinet 50. The clamp 20 and the locking device 60 can be quickly locked onto the utility pole 10. Then, the first connector 30 and the second connector 40 are assembled onto the clamp 20 to lock the power distribution cabinet 50 and complete the fixed installation of the power distribution cabinet 50.

[0034] Please see Figures 2-4 Each clamping device 20 includes two sets of semi-clamps 21 hinged together by a movable pin 22. Each set of semi-clamps 21 has an integrally formed connecting ear 23. The inner sidewall of each set of semi-clamps 21 is staggered from top to bottom with a first pressure plate 24, a second pressure plate 25, a third pressure plate 26, a fourth pressure plate 27, and a fifth pressure plate 28 arranged in an arc. The locking device 60 is locked onto the two sets of connecting ears 23. In use, the two sets of semi-clamps 21 can rotate around the movable pin 22, which allows the semi-clamps 21 to adjust their position according to the thickness of the utility pole 10, thereby clamping them onto the utility pole 10. Then, the locking device 60 is installed at the connecting ears 23 on the two sets of semi-clamps 21. The device 60 includes a bolt 62 connecting two sets of connecting ears 23. A plug plate 61 is fixedly installed at one end of the bolt 62. An anti-loosening air bag 63 is sleeved on the outside of the bolt 62 and clamped between the two sets of connecting ears 23. A locking nut 64 is threaded onto the other end of the bolt 62. The bolt 62 passes through the two sets of connecting ears 23, while the plug plate 61 abuts against one set of connecting ears 23. The locking nut 64 is threaded onto the bolt 62, completing the connection of the two sets of connecting ears 23. Moreover, the anti-loosening air bag 63 is installed between the two sets of connecting ears 23. The compression of the anti-loosening air bag 63 gives the connecting ears 23 a squeezing force on the locking nut 64, increasing the friction between the locking nut 64 and the bolt 62, and increasing the locking force.

[0035] Please see Figure 2 and Figure 5The first connector 30 includes two sets of parallel guide rails 31. Each set of guide rails 31 has a slide rail 32 at its top, and a slide block 33 is slidably fitted in each slide rail 32. A reinforcing rib 34 is fixedly connected between the two sets of slide blocks 33. A limiting cylinder 35, which engages and is fitted between the two sets of semi-clamps 21, is fixedly fitted at the bottom center of the reinforcing rib 34. The second connector 40 has the same structure. The reinforcing rib 34 is located on top of the clamp 20, and the limiting cylinder 35 is inserted between the two sets of semi-clamps 21 to complete the limiting. The slide blocks 33 at both ends of the reinforcing rib 34 are slidably fitted in the slide rails of the guide rails 31. Inside 32, the position of the slide 33 on the guide rail 31 is easily adjusted, and the distance between the clamp 20 and the distribution cabinet 50 is easily adjusted in real time according to the distance between the two sets of utility poles 10. After the clamp 20 is installed on the utility pole 10, the connection between the clamp 20 and the distribution cabinet 50 is realized through the first connector 30 and the second connector 40. The distance between the first connector 30 and the second connector 40 and the distribution cabinet 50 can be adjusted in real time according to the distance between the two sets of utility poles 10, which improves the adaptability of the connection unit when the distribution cabinet 50 is installed on the utility pole 10.

[0036] The first connector 30 also includes a first support seat 36 fixed to the end of the guide rail 31. Each set of first support seats 36 has a shock-absorbing air bag 37 fixedly installed on its top. The second connector 40 also includes a second support seat 41 fixed to the end of the guide rail 31. The first support seat 36 is used to limit the installation inside the distribution cabinet 50, support the distribution cabinet 50, and limit the distance between the guide rail 31 and the distribution cabinet 50. Similarly, the second support seat 41 on the second connector 40 is also used to facilitate the limit installation between the second connector 40 and the distribution cabinet 50, improve the ease of installation, and the shock-absorbing air bag 37 can block the rigid connection between the first support seat 36 and the distribution cabinet 50, improve the buffering effect of the distribution cabinet 50 after it is fixedly installed on the utility pole 10, and achieve windproof and impact protection.

[0037] Please see Figures 2-5 The reinforcing ribs 34 are mounted on top of the two sets of semi-clamps 21. The slide rail 32 is a T-shaped slide groove. Each set of slide seats 33 has a pressure-bearing air bag fixed on the side wall away from the power distribution cabinet 50. The other end of the pressure-bearing air bag is fixed on the inner side wall of the slide rail 32. Each set of pressure-bearing air bags is connected to its corresponding shock-absorbing air bag 37 through the air guide pipe. In actual use, the slide seat 33 can move inside the slide rail 32 to facilitate the adjustment of the distance between the slide seat 33 and the power distribution cabinet 50. When the slide seat 33 moves inside the slide rail 32, the slide seat 33 has a squeezing effect on the pressure-bearing air bag, which causes the gas in the pressure-bearing air bag to be introduced into the shock-absorbing air bag 37 through the air guide pipe, thereby causing the shock-absorbing air bag 37 to expand and increase the shock-absorbing air bag 37's impact-resistant buffer protection effect on the power distribution cabinet 50 during use.

[0038] The connecting unit also includes a fixed pin 29 integrally formed with the bottom end of the movable pin 22, and the fixed pin 29 is inserted and installed at the bottom of the limiting cylinder 35. A sealing air bag 210 is fixedly sleeved on the outer wall of the fixed pin 29, and each set of sealing air bags 210 is connected to its corresponding anti-loosening air bag 63 through an air supply pipe.

[0039] In actual use, after the clamp 20 is installed on the utility pole 10, the locking device 60 locks the clamp 20. Simultaneously, the limiting cylinder 35 is fitted onto the fixing pin 29, limiting the first connector 30 and the second connector 40. At the same time, since the locking device 60 is locked onto the clamp 20, the anti-loosening air bag 63 is compressed. Then, the gas inside the anti-loosening air bag 63 is introduced into the sealing air bag 210 through the air supply pipe, causing the sealing air bag 210 to expand and be sealed inside the limiting cylinder 35. This completes the compression and limiting of the fixing pin 29 inside the limiting cylinder 35, preventing the limiting cylinder 35 from detaching from the fixing pin 29, and increasing the stability of the first connector 30 and the second connector 40 on the clamp 20.

[0040] Please see Figures 2-4 The first pressure plate 24, the second pressure plate 25, the third pressure plate 26, the fourth pressure plate 27, and the fifth pressure plate 28 have the same structure. The first pressure plate 24 includes a limiting clip that is hinged to the inner wall of the semi-clamp 21 via a hinge shaft. A rubber sheet is fixed to the side wall of the limiting clip near the semi-clamp 21. In actual use, since the limiting clip can rotate around the hinge shaft on the inner wall of the semi-clamp 21, when the semi-clamp 21 is fitted onto the utility pole 10, the angle of the limiting clip relative to the utility pole 10 can be adjusted by rotating the limiting clip, thereby increasing the clamping range of the clamping device 20. This makes it easier for the limiting clip to face the utility pole 10, thereby increasing the clamping force of the limiting clip on the utility pole 10 when the clamping device 60 is used to lock the clamping device 20 onto the utility pole 10, and improving the anti-fall-off ability of the clamping device 20 on the utility pole 10.

[0041] Example 2:

[0042] like Figures 1 to 8As shown, this embodiment discloses a high-altitude power distribution cabinet, including the power distribution cabinet safety connection structure as described in Embodiment 1, including a power distribution cabinet body 50, a base 51 fixedly installed at the bottom of the power distribution cabinet body 50, and limiting grooves 52 matching the first support seat 36 on both the left and right sides of the bottom of the base 51. Support seats 53 are fixedly installed on the top of the left and right side walls of the power distribution cabinet body 50, and the second support seat 41 is engaged and assembled on the support seat 53. In actual use, the clamping device 20 is first installed on the utility pole 10, and the locking device is used to secure it. The clamp 20 is pre-locked by the clamp 60. Simultaneously, the first connector 30 is limited and installed in the limiting groove 52, while the second connector 40 is limited and assembled on the support 53. Then, the first connector 30 and the second connector 40 are respectively assembled on the clamp 20. At the same time, the clamp 20 is locked by the locking device 60. Thus, the power distribution cabinet 50 can be installed on the clamp 20 through the first connector 30 and the second connector 40, completing the installation of the power distribution cabinet 50 on the utility pole 10 with high convenience.

[0043] Please see Figure 8 Mounting slots are provided on the bottom of the left and right side walls of the base 51 and on the support 53. The size of the mounting slots matches that of the guide rail 31. The mounting slot on the lower side is connected to the limiting slot 52. The shock-absorbing air bag 37 is stored and assembled inside the limiting slot 52. The mounting slot facilitates the storage of the guide rail 31 and can effectively limit the guide rail 31, ensuring the stability of the first connector 30 and the second connector 40 on the power distribution cabinet 50 and preventing shaking. Moreover, after the power distribution cabinet 50 is installed, the locking device 60 fixes the clamp 20 on the utility pole 10. The clamp 20 can limit the first connector 30 and the second connector 40. The first connector 30, the second connector 40 and the power distribution cabinet 50 are fitted together with a limiting assembly. Therefore, the power distribution cabinet 50 is fixed on the utility pole 10 through a safe connection structure.

[0044] It is worth noting that the horizontal position of the distribution cabinet 50 relative to the guide rail 31 is fixed, and the horizontal position of the clamp 20 relative to the reinforcing rib 34 is also fixed. However, the reinforcing rib 34 can slide on the guide rail 31. Therefore, the position of the clamp 20 relative to the distribution cabinet 50 can be adjusted in real time by utilizing the mobility of the slide block 33 on the guide rail 31. This allows the reinforcing rib 34 to be adaptively adjusted on the guide rail 31 according to the distance between the two sets of utility poles 10, thus facilitating the distribution cabinet 50 to cope with the uneven distances between utility poles 10 when installed outdoors, thereby improving its adaptability.

[0045] It should be noted that the length of the slide rail 32 is the adjustable stroke of the safety connection structure. Based on this, when the power distribution cabinet 50 is installed on the utility pole 10 using the safety connection structure, the increase in distance between the two sets of utility poles 10 is within the adjustable stroke. This avoids the situation where the power distribution cabinet 50 cannot be installed due to the large distance between the utility poles 10. Moreover, as long as the slide block 33 has a movement distance within the slide rail 32, the slide block 33 will exert a compressive force on the pressure-bearing air bag, which will then output gas pressure that causes the shock-absorbing air bag 37 to expand. This facilitates the shock absorption and buffering of the power distribution cabinet 50 through the shock-absorbing air bag 37. When the power distribution cabinet 50 is subjected to strong wind impact, it can prevent the power distribution cabinet 50 and the safety connection structure from experiencing excessive internal stress due to rigid connection, which could lead to structural breakage.

[0046] Please see Figures 6-8 The base 51 has locking grooves on its front and rear side walls that correspond to the mounting grooves. A locking strip 54 is inserted into the locking groove. The guide rail 31 is located on top of the locking strip 54. The locking strip 54 blocks and limits the guide rail 31. After the first support 36 is installed inside the limiting groove 52, the locking strip 54 is inserted into the locking groove. Thus, the bottom of the guide rail 31 can be blocked by the locking strip 54 to prevent the guide rail 31 from falling out of the limiting groove 52, thereby improving the installation stability of the first connector 30 on the power distribution cabinet 50.

[0047] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
