Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and more particularly to an adjustable distribution box. Background Technology

[0002] Distribution boxes are an important component of electrical equipment. Their main function is to distribute electrical energy to a circuit of the upstream power distribution equipment, and to control, measure, transmit signals and protect the wiring scheme. They are a key node to ensure the stable operation of the power system at the end and are widely used in industrial, commercial and civil buildings.

[0003] With the advancement of smart grid construction, distribution boxes, as key terminals for power distribution and data collection, are being installed in increasingly diverse scenarios, especially in rural power grid renovation, urban street light power supply, and outdoor communication base stations, where the installation requirements are becoming more stringent.

[0004] However, most existing distribution boxes are installed using traditional fixed planar installation methods, which involve rigidly fixing the distribution box to the wall or bracket with bolts. But considering that distribution boxes are mainly used in outdoor power construction projects such as urban and rural power grid renovation, road lighting, and 5G base station power supply, they typically need to be directly installed on columnar carriers such as utility poles and streetlight poles. Traditional planar installation methods, and the use of rigid clamps or fixed-diameter clamps, cannot adapt to the actual contours of the pole and lack a reliable fixing foundation. Furthermore, outdoor poles are exposed to the natural environment for a long time, and their diameters often vary due to production mold tolerances, surface wear or deformation caused by years of use, and even have a certain degree of ellipticity deviation. This can easily lead to poor contact surfaces and localized stress concentration. Once strong winds or slight deformation of the pole occur, a single fixing point is prone to loosening, slippage, or even detachment due to a lack of buffering and dynamic adjustment capabilities. In addition, the existing installation structure lacks the ability to adjust for circumferential deformation of the pole, making maintenance and adjustment cumbersome and failing to meet the requirements for long-term stable mounting of power distribution facilities in complex outdoor environments. Summary of the Invention

[0005] This application provides an adjustable distribution box that solves the technical problems in the prior art, such as the inability to flexibly adapt to the cylindrical surface of utility poles for installation, difficulties in high-altitude operations leading to fall hazards, insufficient anti-slipping ability, lack of anti-overturning constraints that easily cause overturning, and lack of self-adaptive ability under dynamic disturbances leading to loosening of the fixation. It achieves the technical effects of improving rapid positioning and installation efficiency, enhancing anti-slipping ability, improving anti-overturning stability through spatial cross-angle traction, suppressing dynamic disturbances through adaptive compensation fixing force, and improving installation reliability.

[0006] This application provides an adjustable distribution box, including a base plate, a pole, a distribution box body, a support plate, and an installation and adjustment unit; The distribution box body and the support plate are both fixed on the base plate; the support plate is located on the side of the distribution box body closest to the pole; the installation adjustment unit is located on the side of the support plate closest to the pole. The installation adjustment unit includes two rings fixed to the side of the support plate near the pole. Each ring includes a main ring block, a secondary ring block, a snap-fit ​​block, and a positioning groove. Multiple main ring blocks and secondary ring blocks are interconnected to form an arc-shaped structure, which fixes the distribution box body to the pole and adaptively adjusts to the shape of the pole.

[0007] Furthermore, there are multiple main ring blocks, and the number is odd. They are connected by hinges to form an arc-shaped structure, and the main ring block located in the middle position is fixed on the support plate. Two secondary ring blocks are provided, located at both ends of the arc-shaped structure formed by the main ring block, and are hinged to the adjacent main ring blocks; one of the secondary ring blocks has a positioning groove at the end away from the corresponding adjacent main ring block, and the other secondary ring block has a snap-fit ​​block fixed at the end away from the corresponding adjacent main ring block.

[0008] Furthermore, the snap-fit ​​block is made of magnetic metal; an electromagnetic block is provided inside the positioning groove, and the snap-fit ​​block and the positioning groove engage with each other through magnetic force to achieve the initial fixation of the pole by the retaining ring.

[0009] Furthermore, the main ring block and the secondary ring block are U-shaped structures and each has a stabilizing bladder fixed inside. In the initial state, two adjacent stabilizing bladders are connected to each other through a connecting pipe. The outer layer of the stabilizing bladder is provided with friction texture and its interior is filled with hydraulic oil. When hydraulic oil is injected into the stabilizing bladder in the main ring block located in the middle, the hydraulic oil flows through the connecting pipe to other stabilizing bladders connected to it, forcing the stabilizing bladders to expand and fit tightly against the outer surface of the pole, thus achieving flexible pressure fixation.

[0010] Furthermore, the installation adjustment unit also includes adjustment components, which are provided in two sets. The two sets of adjustment components are fixed on the front and rear opposite sides of the distribution box body respectively. Each set of adjustment components includes two adjustment components arranged in a mirror image above and below, which are used to pull and fix the ring for a secondary fixation. A composite plate is fixed to the outer side of the end of the secondary ring block. After the main ring block and the secondary ring block form a ring structure, the two composite plates are joined together.

[0011] Furthermore, the adjustment assembly includes a fixed housing, a winding drum, a fastening rope, and an adjustment bolt; The fixed shell is fixed to the side of the distribution box body and its opening end is the outlet of the fastening rope; the winding drum is fixed inside the fixed shell and is driven to rotate by the motor inside it. In the initial state, one end of the fastening rope is wound onto the winding drum, and the other end extends out of the opening end of the fixing shell and is wrapped and fixed to the adjusting bolt. The adjusting bolt fixes the two corresponding plates by means of threaded connection.

[0012] Furthermore, guide wheels are fixed to the facing end faces of the upper and lower main ring blocks; the guide wheels include a bracket and a core cylinder; The core tube is fixed to the corresponding main ring block by a bracket; the fastening rope is wrapped around the outside of the core tube, and the fastening rope is wound up by adjusting the bolt, thereby pulling and tightening multiple main ring blocks.

[0013] Furthermore, after the fastening rope extends from the fixed shell, it passes around multiple guide wheels located on one side of the fastening rope in a wave-like manner; after the two fastening ropes at the same height are wound around the corresponding guide wheels in sequence, they form an encircling embrace around the pole. Two fastening ropes, which are wrapped around the same set of guide wheels located above, are respectively fixedly wound around the corresponding adjusting bolts located below; two fastening ropes, which are wrapped around the same set of guide wheels located below, are respectively fixedly wound around the corresponding adjusting bolts located above, forming a cross-angled traction and fixing structure; two adjusting bolts, which are connected by threads to the same set of corresponding plates, are arranged alternately up and down.

[0014] Furthermore, a liquid bladder is built into the side of the core cylinder that contacts the fastening rope, and the liquid bladder has a fan-shaped structure; flow channels are opened at the docking points of the bracket and the main ring block; the liquid bladder communicates with the corresponding stabilizing bladder through the flow channels.

[0015] Furthermore, the diameter of the flow channel is three to five times the diameter of the connecting pipe; a pressure membrane is provided inside the flow channel. When the internal pressure of the corresponding stabilizing bladder increases to the preset opening threshold of the pressure diaphragm, the pressure diaphragm opens, allowing the hydraulic oil in the corresponding stabilizing bladder to flow into the corresponding liquid bladder through the flow channel, causing it to expand, and then tightening the corresponding fastening rope wrapped around its outside accordingly.

[0016] One or more technical solutions provided in this application have at least the following technical effects or advantages: By setting the main ring block and the secondary ring block to be hinged to each other for adaptive deflection, and by using the magnetic snap-fit ​​of the snap-fit ​​block and the positioning groove, the ring can quickly adapt to the outline of the pole and achieve one-click preliminary positioning, reducing the risk of high-altitude operations; by setting multiple stabilizing bladders and quickly filling them with hydraulic oil through connecting pipes, and then performing coordinated flexible expansion after filling, full-contact pressure fixing can be achieved, thereby eliminating stress concentration; by setting an adjustment component (i.e., through the cooperation of guide wheels, fastening ropes, and adjusting bolts), a spatial cross-angle traction action is formed by a wave-like rope winding method, achieving three-dimensional constraint force, which can counteract the overturning moment and improve the anti-overturning stability. This technology represents a significant improvement. By incorporating flow channels and liquid bladders in conjunction with fastening ropes, it enables hydraulic oil to rapidly flow into the liquid bladders under dynamic disturbances, expanding and tightening the fastening ropes. This allows for adaptive adjustment of the traction and pre-tensioning force. It effectively solves the technical problems of existing technologies, such as the inability to flexibly adapt to cylindrical pole installations, difficulties in high-altitude operations leading to fall hazards, insufficient anti-slipping capabilities, lack of anti-overturning constraints causing overturning, and lack of adaptive capabilities under dynamic disturbances leading to loosening. The technology achieves improved efficiency in rapid positioning and installation, enhanced anti-slipping capabilities, improved anti-overturning stability through spatial cross-angle traction, adaptive compensation of the fixing force to suppress dynamic disturbances, and improved installation reliability.

Detailed Implementation

[0025] To facilitate understanding of the present invention, a more complete description of this application will be given below with reference to the accompanying drawings, which illustrate preferred embodiments of the invention. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of the present invention.

[0026] It should be noted that the terms "vertical," "horizontal," "up," "down," "left," "right," and similar expressions used in this article are for illustrative purposes only and do not represent the only possible implementation.

[0027] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains; the terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to limit the invention; the term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0028] Example 1: As Figures 1 to 4 As shown, this application discloses an adjustable distribution box, which includes a base plate 100, a pole 101, a distribution box body 110, a support plate 120, and an installation and adjustment unit 200. The distribution box body 110 and the support plate 120 are both fixed on the base plate 100; the support plate 120 is located on the side of the distribution box body 110 near the pole 101; the installation adjustment unit 200 is located on the side of the support plate 120 near the pole 101. The installation adjustment unit 200 includes two rings fixed to the side of the support plate 120 near the pole 101. The rings include a main ring block 210, a secondary ring block 220, a snap-fit ​​block 230, and a positioning groove 240. The main ring blocks 210 and the secondary ring blocks 220 are interconnected to form an arc-shaped structure, which fixes the distribution box body 110 on the pole 101 and adapts to the outer contour of the pole 101 for adaptive adjustment.

[0029] like Figures 1 to 4As shown, there are multiple main ring blocks 210, and the number is odd. They are connected by hinges to form an arc-shaped structure. The main ring block 210 located in the middle position is fixed on the support plate 120. Two sub-ring blocks 220 are provided, located at both ends of the arc-shaped structure formed by the main ring block 210, and are hinged to each other with the adjacent main ring block 210; one of the sub-ring blocks 220 has a positioning groove 240 at the end away from the corresponding adjacent main ring block 210, and the other sub-ring block 220 has a snap-fit ​​block 230 fixed at the end away from the corresponding adjacent main ring block 210.

[0030] The snap-fit ​​block 230 is made of magnetic metal; an electromagnetic block is provided inside the positioning groove 240. The snap-fit ​​block 230 and the positioning groove 240 engage with each other through magnetic force, thereby achieving the initial fixation of the retaining ring on the pole 101.

[0031] This application sets up multiple main ring blocks 210 that are hinged together and spliced ​​together with secondary ring blocks 220 to form an arc-shaped ring. Combined with the magnetic quick-locking action of the snap-fit ​​block 230 and the positioning groove 240, this allows the ring to adaptively wrap around the outline of the pole 101 and achieve one-click initial positioning. This reduces the time spent repeatedly adjusting the ring size during high-altitude operations and solves the problem that traditional rigid clamps and fixed-diameter clamps cannot flexibly adapt to differences in pole specifications. It also reduces the risk of falls from heights. Specifically, when the operator wraps the assembled ring around the pole... When pole 101 is in use, the arc-shaped structure composed of multiple main ring blocks 210 and secondary ring blocks 220 can adaptively deflect according to the outer contour of the pole body and automatically fit the curved surface of the pole body; then the snap-fit ​​block 230 and the positioning groove 240 instantly complete the adsorption and snap-fit ​​under electromagnetic action, realizing the convenient preliminary positioning and pre-fixation of the ring on the pole 101, eliminating the cumbersome assembly and debugging process, thereby shortening the single-person operation time of high-altitude workers, reducing the physical consumption and fall risk caused by long-term high-altitude suspension, and making this application flexibly applicable to the high-altitude installation of poles of different specifications.

[0032] like Figures 1 to 4 As shown, the main ring block 210 and the secondary ring block 220 are U-shaped structures and each has a stabilizing bladder 250 fixed on its inner side. In the initial state, two adjacent stabilizing bladders 250 are connected to each other through a connecting pipe 252. The outer layer of the stabilizing bladder 250 is provided with friction texture and its interior is filled with hydraulic oil 251. When hydraulic oil 251 is injected into the stabilizing bladder 250 in the main ring block 210 located in the middle position, the hydraulic oil 251 flows through the connecting pipe 252 to other stabilizing bladders 250 connected to it, forcing the stabilizing bladders 250 to expand and stick tightly to the outer surface of the pole 101, thereby achieving flexible pressure fixation.

[0033] This application, by setting up multiple stabilizing bladders 250, connecting pipes 252, and hydraulic oil 251, can solve the problems of slippage and local stress concentration caused by non-adherence of contact surfaces in rigid fixing. Specifically, hydraulic oil 251 is injected into the stabilizing bladders 250 located in the central main ring block 210. The hydraulic oil 251 flows through the connecting pipes 252 to all the stabilizing bladders 250 connected to it, forcing the outer stabilizing bladders 250 with friction texture to expand flexibly at the same time. This allows the stabilizing bladders 250 to adhere to the outer surface of the pole 101, thereby reducing local stress concentration, achieving contact-type flexible pressure fixing, improving anti-slip capability, and reducing the risk of slippage caused by non-adherence of contact surfaces in traditional rigid fixing.

[0034] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the installation adjustment unit 200 also includes an adjustment component 270. The adjustment component 270 is provided in two sets, and the two sets of adjustment components 270 are respectively fixed on the front and rear opposite sides of the distribution box body 110. Each set of adjustment components 270 includes two adjustment components 270 arranged in a mirror image above and below, which are used to pull and fix the ring for a secondary fixation. like Figure 4 As shown, a composite plate 231 is fixed to the outer side of the end of the secondary ring block 220. After the main ring block 210 and the secondary ring block 220 form a ring structure, the two composite plates 231 are engaged.

[0035] like Figure 1 , Figure 2 , Figure 5 and Figure 6 As shown, the adjustment assembly 270 includes a fixed housing 271, a winding drum 272, a fastening rope 273, and an adjustment bolt 274; The fixed housing 271 is fixed to the side of the distribution box body 110 and its opening end is the outlet of the fastening rope 273; the winding drum 272 is fixed inside the fixed housing 271 and is driven to rotate by the motor inside it. In the initial state, one end of the fastening rope 273 is wound onto the winding drum 272, and the other end extends out of the opening end of the fixing shell 271 and is wrapped and fixed onto the adjusting bolt 274. The adjusting bolt 274 fixes the two corresponding plates 231 by means of threaded connection.

[0036] like Figure 2 , Figure 3 , Figure 5 and Figure 7 As shown, guide wheels 260 are fixed to the facing end faces of the two main ring blocks 210, one above the other; the guide wheel 260 includes a bracket 261 and a core cylinder 262. The core cylinder 262 is fixed to the corresponding main ring block 210 by the bracket 261; the fastening rope 273 is wrapped around the outside of the core cylinder 262, and the fastening rope 273 is wound up by the adjusting bolt 274, thereby pulling and tightening the multiple main ring blocks 210.

[0037] like Figure 1 , Figures 2 to 5 As shown, after the fastening rope 273 extends out from the fixed shell 271, it passes around multiple guide wheels 260 located on one side of the fastening rope 273 in a wave-like manner; after the two fastening ropes 273 at the same height are wound around the corresponding guide wheels 260 in sequence, they form an encircling embrace around the pole 101. Two fastening ropes 273, which are wrapped around the same set of guide wheels 260 located above, are respectively fixedly wound around the corresponding adjusting bolts 274 located below; two fastening ropes 273, which are wrapped around the same set of guide wheels 260 located below, are respectively fixedly wound around the corresponding adjusting bolts 274 located above, forming a cross-angled traction and fixing structure; two adjusting bolts 274, which are threadedly connected to the same set of corresponding composite plates 231, are arranged alternately up and down.

[0038] This application solves the problem of weak anti-overturning ability of a single fixed point and easy tipping under strong winds or external forces by setting two sets of mirror-arranged adjustment components 270, namely, the coordinated cooperation of the fixed shell 271, the winding drum 272, the fastening rope 273, the guide wheel 260, the adjusting bolt 274 and the composite plate 231. Specifically, two sets of adjustment components 270 are fixed to the front and rear opposing sides of the distribution box body 110 respectively. The motor-driven winding drum 272 inside the fixed shell 271 actively winds up and unwinds the fastening rope 273. Before installation, the installer winds the fastening rope 273 in a wave-like manner, passing it around the guide wheels 260 on the opposite sides of the upper and lower main ring blocks 210 in sequence. This forms a spatial cross angle pull where the upper fastening rope 273 is wound around the lower adjustment bolt 274 and the lower fastening rope 273 is wound around the upper adjustment bolt 274. At the same time, the staggered adjustment bolts 274 can thread-fix the end plate 231 of the secondary ring block 220, so that the ring and the distribution box body 110 are subject to balanced tension constraints from the front, back, top, bottom and left and right three-dimensional directions, thereby offsetting the lateral overturning moment and further improving the anti-overturning stability.

[0039] like Figure 3 , Figure 5 and Figure 7 As shown, a liquid bladder 263 is built into the side of the core cylinder 262 that is in contact with the fastening rope 273. The liquid bladder 263 has a fan-shaped structure. A flow channel 264 is provided at the docking point of the bracket 261 and the main ring block 210. The liquid bladder 263 communicates with the corresponding stabilizing bladder 250 through the flow channel 264.

[0040] The diameter of the flow channel 264 is three to five times the diameter of the connecting pipe 252; a pressure membrane is provided inside the flow channel 264. When the internal pressure of the corresponding stabilizing bladder 250 increases to the preset opening threshold of the pressure diaphragm, the pressure diaphragm opens, allowing the hydraulic oil 251 in the corresponding stabilizing bladder 250 to flow into the corresponding liquid bladder 263 through the flow channel 264, causing it to expand, and then the corresponding fastening rope 273 wrapped around its outside is tightened accordingly.

[0041] This application, by setting up a flow channel 264, a pressure membrane, and a liquid bladder 263, and cooperating with a fastening rope 273 to form a pressure-triggered fixed tension compensation, can solve the problems of traditional installation structures lacking self-adaptive ability and being prone to loosening or even falling off under dynamic disturbances such as strong winds or center of gravity shifts. Specifically, when the distribution box body 110 shakes or tilts due to strong winds or maintenance stress, the stabilizing bladder 250 in the corresponding direction of the main ring block 210 is compressed and deformed, and the pressure of the hydraulic oil 251 inside it instantly rises to the preset opening threshold of the pressure membrane in the flow channel 264. Furthermore, since the diameter of the flow channel 264 is designed to be three to five times that of the connecting pipe 252 (i.e., the large diameter ensures that the high-pressure hydraulic oil 251 can pass through the flow channel 264 quickly, prioritizing the connection pipes 252 on both sides), the hydraulic oil 251 preferentially flows into the flow channel 264 at high speed. The fan-shaped liquid bladder 263 inside the core cylinder 262 then expands in a directional manner, directly tightening the fastening rope 273 wrapped around its outer side. This allows the pre-tension force of the fastening rope 273 to be quickly and automatically compensated, thereby dynamically offsetting the overturning moment and suppressing further shaking of the box. This achieves automatic compensation of rigid tension adjustment, enabling the distribution box body 110 to maintain long-term stability in complex high-altitude environments without manual intervention throughout the entire use process after installation, thus improving the stability after installation.

[0042] The distribution box body 110 integrates a smart meter, circuit breaker, and communication module for data acquisition and remote control of the smart grid; this is existing technology and will not be described in detail here. The installation adjustment unit 200 is configured to automatically increase the preload of the fastening rope 273 through the hydraulic linkage between the stabilizing bladder 250 and the liquid bladder 263 when the distribution box body 110 shakes due to strong winds or a shift in its center of gravity, thereby maintaining the stability of the distribution box body 110 and improving installation flexibility and stability.

[0043] In actual operation, the steps of this embodiment are as follows: Before installing the distribution box body 110 on the pole 101, the operator first assembles the corresponding number and specifications of main ring blocks 210 and secondary ring blocks 220 according to the size of the pole 101, and then winds and fixes the four fastening ropes 273 in a wave-like manner through the corresponding guide wheels 260 and the corresponding adjusting bolts 274; then, the operator climbs the pole 101 and surrounds the ring to the designated height of the pole 101, and achieves the initial fixation of the distribution box body 110 through magnetic attraction; then, the main ring blocks 210 and secondary ring blocks 220 are tightly fitted and fixed to the pole 101 by filling hydraulic oil 251; finally, the adjusting bolts 274 are fixed on the corresponding mating plate 231, and the fastening ropes 273 connected to them are cross-pulled and adjusted by rotating the adjusting bolts 274, thereby tightening and installing the distribution box body 110, and achieving the final installation.

[0044] When the main body 110 of the distribution box installed at a high position shakes or is damaged and needs to be repaired by maintenance personnel, the main body 110 of the distribution box may become unstable or tilted during the repair process. At this time, due to the tilt of the main body 110 of the distribution box, the stabilizing bladder 250 in the corresponding part of the main ring block 210 is squeezed, and the internal pressure of the stabilizing bladder 250 increases. The hydraulic oil 251 in the corresponding stabilizing bladder 250 preferentially enters the corresponding liquid bladder 263 through the internal flow channel 264, causing it to expand. Then, the corresponding fastening rope 273 wrapped around its outside is tightened accordingly to resist the shaking or tilting of the main body 110 of the distribution box.

[0045] The technical solutions described in the embodiments of this application above have at least the following technical effects or advantages: This adjustable distribution box, through the hinged connection of the main ring block 210 and the secondary ring block 220 for adaptive deflection and the magnetic engagement of the snap-fit ​​block 230 and the positioning groove 240, can achieve rapid adaptation of the ring to the contour of the pole 101 and one-click initial positioning, reducing the risk of high-altitude operations; by setting multiple stabilizing bladders 250 and quickly filling the connected stabilizing bladders 251 with hydraulic oil through the connecting pipe 252, and performing coordinated flexible expansion after filling, it achieves full-contact pressure fixation, thereby eliminating stress concentration; by setting the adjustment component 270 (i.e., through the guide wheel 260, the fastening rope 273, and the adjustment...), it can achieve rapid adaptation of the ring to the contour of the pole 101 and one-click initial positioning, reducing the risk of high-altitude operations; by setting multiple stabilizing bladders 250 and quickly filling the connected stabilizing bladders 251 with hydraulic oil through the connecting pipe 252, and performing coordinated flexible expansion after filling, it can achieve full-contact pressure fixation, thereby eliminating stress concentration; by setting the adjustment component 270 (i.e., through the guide wheel 260, the fastening rope 273, and the adjustment...), it can achieve rapid adaptation of the main ring block 210 and the secondary ring block 220 for adaptive deflection and the magnetic engagement of the connecting block 230 and the positioning groove 240, reducing the risk of high-altitude operations. With the cooperation of bolt 274, a spatial cross-angle traction action is formed by a wave-like rope winding method to achieve three-dimensional constraint force, which can offset the overturning moment and further improve the anti-overturning stability. By setting up flow channel 264 and liquid bladder 263 and cooperating with fastening rope 273, hydraulic oil 251 can quickly flow into liquid bladder 263 to expand and tighten fastening rope 273 under dynamic disturbance, realizing adaptive adjustment of traction and fixing pre-tightening force. It achieves the technical effects of improving rapid positioning and installation efficiency, enhancing anti-slip capability, improving anti-overturning stability through spatial cross-angle traction, adaptive compensation of fixing force to suppress dynamic disturbance, and improving installation reliability.
