Description

Technical Field

[0001] This utility model relates to the field of circuit breaker support technology, and in particular to a support for a pole-mounted circuit breaker. Background Technology

[0002] Outdoor pole-mounted circuit breakers are widely used in the power distribution systems of substations and industrial and mining enterprises for the protection and control of circuits. They are particularly suitable for the construction and renovation of urban and rural power grids, as well as locations requiring frequent operation. During installation, brackets are usually required to stably mount the circuit breaker on the outdoor pole.

[0003] The existing pole-mounted circuit breaker brackets are used by placing a retaining ring on the outdoor pole, then placing the bracket body on the retaining ring, and then tightening the fastening nuts at both ends of the retaining ring in sequence. The fastening nuts press and hold the bracket body by squeezing the surface of the bracket body, thus fixing the bracket body to the outdoor pole. Then the circuit breaker is installed on the bracket body, and the bracket body provides support for the circuit breaker.

[0004] However, since the clamps require a large number of fastening nuts to secure the frame, the installation process may require personnel to tighten multiple fastening nuts sequentially. Furthermore, the clamps are located at different heights, requiring workers to adjust their own height to tighten the fastening nuts at different heights. This makes the frame installation process cumbersome, time-consuming, and labor-intensive, thus affecting the efficiency of the frame installation. Utility Model Content

[0005] The technical problem this utility model aims to solve is that, since the retaining ring requires a large number of fastening nuts to fix the frame, it may be necessary for personnel to tighten multiple fastening nuts sequentially during installation. Furthermore, since the retaining ring is at different heights, workers also need to adjust their own height to tighten fastening nuts at different heights, making the frame installation process cumbersome, time-consuming, and labor-intensive, thus affecting the efficiency of frame installation.

[0006] The technical solution adopted by this utility model to solve its technical problem is: a bracket for a pole-mounted circuit breaker, comprising: a frame body, wherein a plurality of mounting holes are provided on one side of the frame body, wherein the mounting holes are used to assist in installing the circuit breaker on the frame body; and a fixing device, wherein the fixing device is disposed on the frame body, wherein the fixing device quickly installs the frame body on an outdoor pole by clamping and fixing.

[0007] Preferably, the fixing device includes: a guide rail fixed to the frame, wherein a bidirectional screw is rotatably connected inside the guide rail via a bearing, and the surface threads of the bidirectional screw are arranged in opposite symmetrical patterns; two concave rods symmetrically threadedly connected to the bidirectional screw inside the guide rail, wherein the concave rods slide inside the guide rail, and bolts are threadedly connected to the inner walls of the holes of the concave rods; and two clamping plates slidably mounted on the two concave rods via multi-hole rods, wherein the multi-hole rods are fixed inside the concave rods by bolts.

[0008] The effect achieved by the above components is as follows: By setting up a fixing device, firstly, manually move the clamping plate to drive the perforated rod to move left and right along the inside of the concave rod. When the clamping plate moves to the appropriate position, the inner wall of the hole on the concave rod coincides with the inner wall of any hole on the perforated rod. At this time, manually screw the bolt into the concave rod and the perforated rod to fix the position of the perforated rod and the clamping plate, completing the position adjustment of the clamping plate. Then, manually move the frame to the position that is in contact with the surface of the outdoor column, so that the two clamping plates are aligned with the middle position of the surface of the outdoor column. At this time, manually rotate the double-acting screw, so that the double-acting screw drives the two concave rods along the inside of the guide rail. The opposing movement causes the two concave rods to drive the two clamping plates to move in opposite directions through the two perforated rods. When the two clamping plates move to the position of pressing against the surface of the outdoor column, they fix the frame in position by clamping the surface of the outdoor column. At the same time, hot melt adhesive is used to bond and reinforce the rotating parts of the bidirectional screw, thereby completing the rapid installation of the frame. This allows personnel to move the frame to a position that is in contact with the surface of the outdoor column and fix the frame to the outdoor column in one go by clamping and fixing it. This reduces the operation steps and time required for personnel to disassemble and assemble the frame, and improves the convenience and efficiency of disassembling and assembling the frame.

[0009] Preferably, one end of the bidirectional screw is fixedly connected to an operating block, wherein the surface of the operating block is in the shape of a cross.

[0010] The effect achieved by the above components is that by setting up the operating block, the contact area of ​​the bidirectional screw can be increased, thereby improving the convenience and stability of manually rotating the bidirectional screw.

[0011] Preferably, it further includes: two push rods, the surfaces of which are slidably connected to the inner walls of the holes in the two clamping plates; two threaded rods, which are fixedly connected to the clamping plates, wherein the two threaded rods are respectively placed inside the two push rods, and the surfaces of the threaded rods are threaded with nuts larger than the inner walls of the push rod holes; and four rubber plates, which are evenly fixed to the two push rods, wherein the surfaces of the rubber plates are provided with multiple protrusions.

[0012] The effect achieved by the above components is as follows: by setting the push rod, when the two clamping plates are clamped on the outdoor post, the nut is rotated by the tool, so that the nut moves along the surface of the threaded rod towards the clamping plate. The nut pushes the rubber plate towards the outdoor post by squeezing the push rod, so that the rubber plate moves to the position of squeezing the surface of the outdoor post and filling the gap between the clamping plate and the surface of the outdoor post. At the same time, the multiple protrusions on the surface of the rubber pad increase the friction between the clamping plate and the surface of the outdoor post, further improving the clamping stability of the clamping plate on the surface of the outdoor post.

[0013] Preferably, each of the two clamps has a storage groove on the side near the hole, wherein the inner wall of the storage groove is larger than the surface of the rubber sheet, and the rubber sheet is placed inside the storage groove for storage.

[0014] The effect achieved by the above components is that by setting up a storage groove, the rubber sheet can be completely stored inside the storage groove, reducing the situation where the surface of the rubber sheet is higher than the surface of the clamping plate, which would affect the normal clamping of the outdoor column by the clamping plate.

[0015] Preferably, multiple anti-slip strips are fixed to adjacent sides of both clamps, and the multiple anti-slip strips are arranged at equal intervals.

[0016] The effect achieved by the above components is that by setting anti-slip strips, the friction and resistance between the clamp and the outdoor post can be increased, reducing the possibility of the clamp sliding.

[0017] Preferably, the inner walls of both clamping plates are fitted with a plurality of filler blocks, wherein the surface of the filler blocks is higher than the surface of the clamping plates.

[0018] The effect achieved by the above components is as follows: by setting the filling block, the personnel can clip the filling block of the corresponding size onto the clamping plate according to the recessed position of the outdoor column surface, so that the filling block can be embedded in the recessed position of the outdoor column surface, further increasing the fit and resistance between the clamping plate and the outdoor column surface.

[0019] Preferably, a limiting post is fixed to one side of each of the two porous rods, wherein the limiting post is placed inside the slide rail on the concave rod and slides left and right.

[0020] The effect achieved by the above components is that by setting the limiting post, the limiting post can be placed inside the slide of the concave rod to intercept the moving multi-hole rod, reducing the possibility of the multi-hole rod detaching from the concave rod.

[0021] The beneficial effects of this utility model are: By setting up a fixing device, personnel can move the frame to a position that fits against the outdoor column surface and fix the frame to the outdoor column in one go using a clamping and fixing method. This reduces the operation steps and time required for personnel to disassemble and assemble the frame, and improves the convenience and efficiency of disassembling and assembling the frame.

[0025] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0026] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0027] Figure 1-6 The bracket for a pole-mounted circuit breaker shown includes: a frame 1, with multiple mounting holes 11 on one side of the frame 1, wherein the mounting holes 11 are used to assist in installing the circuit breaker on the frame 1; and a fixing device 2, which is disposed on the frame 1, wherein the fixing device 2 clamps and fixes the frame 1 to quickly install it on an outdoor pole.

[0028] Figure 2-6The fixing device 2 shown includes: a guide rail 21, which is fixed to the frame 1. A bidirectional screw is rotatably connected inside the guide rail 21 via a bearing, and the threads on the surface of the bidirectional screw are arranged in opposite symmetrical patterns; two concave rods 23, which are symmetrically threaded onto the bidirectional screw inside the guide rail 21, and slide within the guide rail 21. Bolts 25 are threaded onto the inner walls of the holes in the concave rods 23; and two clamping plates 26, which are slidably mounted on the two concave rods 23 via multi-hole rods 24, which are fixed inside the concave rods 23 by bolts 25. By setting up the fixing device 2, the clamping plates 26 are first manually moved to move the multi-hole rods 24 left and right along the inside of the concave rods 23. When the clamping plates 26 move to the appropriate position, the inner walls of the holes on the concave rods 23 coincide with the inner walls of any hole on the multi-hole rods 24. At this point, the bolts 25 are manually screwed into the concave rods 23 and the multi-hole rods 24. The perforated rod 24 and clamping plate 26 are fixed in position, and the position of clamping plate 26 is adjusted. At this time, the frame 1 is manually moved to a position that fits against the surface of the outdoor column, so that the two clamping plates 26 correspond to the middle position of the outdoor column surface. Then, the double-acting screw is manually rotated, so that the double-acting screw drives the two concave rods 23 to move in opposite directions along the inside of the guide rail 21. The two concave rods 23 drive the two clamping plates 26 to move in opposite directions through the two perforated rods 24. When the two clamping plates 26 move in opposite directions to the position that presses against the surface of the outdoor column, the two clamping plates 26 fix the frame 1 in position by clamping the surface of the outdoor column. At the same time, hot melt adhesive is used to bond and reinforce the rotating part of the double-acting screw, thereby completing the quick installation of the frame 1. This allows personnel to move the frame 1 to a position that fits against the surface of the outdoor column and fix the frame 1 to the outdoor column in one go by clamping and fixing it. This reduces the operation steps and time required for personnel to disassemble and assemble the frame 1, and improves the convenience and efficiency of disassembling and assembling the frame 1.

[0029] Figure 2-6 An operating block 22 is fixed to one end of the bidirectional screw shown. The surface of the operating block 22 is in the shape of a star. By setting the operating block 22, the contact area of ​​the bidirectional screw can be increased, thereby improving the convenience and stability of manually rotating the bidirectional screw.

[0030] Figure 2-6The diagram also includes: two push rods 28, the surfaces of which are slidably connected to the inner walls of the holes in the two clamping plates 26; two threaded rods 29, which are fixedly connected to the clamping plates 26, with the two threaded rods 29 respectively placed inside the two push rods 28, and the surfaces of the threaded rods 29 being threaded with nuts larger than the inner walls of the holes in the push rods 28; and four rubber plates 210, which are evenly fixed to the two push rods 28, with the surfaces of the rubber plates 210 having multiple protrusions, which are provided by setting the push rods 28. 8. When the two clamping plates 26 are clamped on the outdoor post, the nut is rotated by the tool, so that the nut moves along the surface of the threaded rod 29 towards the clamping plate 26. The nut pushes the rubber plate 210 towards the outdoor post through the pressing push rod 28, so that the rubber plate 210 moves to the position of pressing the surface of the outdoor post, filling the gap between the clamping plate 26 and the surface of the outdoor post. At the same time, the multiple protrusions on the surface of the rubber pad increase the friction between the clamping plate 26 and the surface of the outdoor post, further improving the clamping stability of the clamping plate 26 on the surface of the outdoor post.

[0031] Figure 2-6 Both clamping plates 26 shown have a storage groove 213 on the side near the hole. The inner wall of the storage groove 213 is larger than the surface of the rubber plate 210. The rubber plate 210 is placed inside the storage groove 213 for storage. By setting the storage groove 213, the rubber plate 210 can be completely stored inside the storage groove 213, reducing the situation where the surface of the rubber plate 210 is higher than the surface of the clamping plate 26, which would affect the normal clamping of the outdoor post by the clamping plate 26. Multiple anti-slip strips 27 are fixed to the adjacent side of the two clamping plates 26. The multiple anti-slip strips 27 are arranged at equal intervals. By setting the anti-slip strips 27, the friction and resistance between the clamping plate 26 and the outdoor post can be increased, reducing the possibility of the clamping plate 26 sliding.

[0032] Figure 2-6 The inner walls of the two clamping plates 26 shown are each fitted with multiple filling blocks 211, the surface of which is higher than the surface of the clamping plate 26. By setting the filling blocks 211, personnel can fit the corresponding size of the filling block 211 into the clamping plate 26 according to the recessed position of the outdoor column surface, so that the filling block 211 can be embedded in the recessed position of the outdoor column surface, further increasing the fit and resistance between the clamping plate 26 and the outdoor column surface. One side of each of the two perforated rods 24 is fixed with a limiting post 212, which slides left and right inside the slide rail on the concave rod 23. By setting the limiting post 212, the limiting post 212 can be placed inside the slide rail of the concave rod 23 to intercept the moving perforated rod 24, reducing the possibility of the perforated rod 24 detaching from the concave rod 23.

[0033] Working principle: First, manually move the clamping plate 26 to move the perforated rod 24 left and right along the inside of the concave rod 23. When the clamping plate 26 moves to the appropriate position, the inner wall of the hole on the concave rod 23 coincides with the inner wall of any hole on the perforated rod 24. At this time, manually screw the bolt 25 into the concave rod 23 and the perforated rod 24 to fix the position of the perforated rod 24 and the clamping plate 26, completing the position adjustment of the clamping plate 26. Then, manually move the frame 1 to the position where it is in contact with the surface of the outdoor column, so that the two clamping plates 26 are aligned with the outdoor column. At the corresponding position in the middle of the surface, manually rotate the bidirectional screw, causing the bidirectional screw to drive the two concave rods 23 to move in opposite directions along the inside of the guide rail 21. This causes the two concave rods 23 to drive the two clamping plates 26 to move in opposite directions through the two perforated rods 24. When the two clamping plates 26 move in opposite directions to the position of pressing the outdoor column surface, the two clamping plates 26 fix the position of the frame 1 by clamping the outdoor column surface. At the same time, hot melt adhesive is used to bond and reinforce the rotating part of the bidirectional screw, thereby completing the rapid installation of the frame 1. At this point, the nut can be rotated using a tool, causing it to move along the surface of the threaded rod 29 towards the clamping plate 26. This causes the nut to push the rubber plate 210 towards the outdoor post via the pressing push rod 28, moving the rubber plate 210 to the position where it presses against the surface of the outdoor post, filling the gap between the clamping plate 26 and the surface of the outdoor post. At the same time, the multiple protrusions on the surface of the rubber pad increase the friction between the clamping plate 26 and the surface of the outdoor post, thus completing the auxiliary reinforcement of the clamping plate 26.
