Description

Technical Field

[0001] This invention relates to the field of power distribution equipment technology, and in particular to a pole-mounted circuit breaker mounting bracket with anti-wind deflection function. Background Technology

[0002] In the "pole-mounted circuit breaker mounting bracket with anti-wind deflection function", the "pole-mounted circuit breaker mounting bracket" is the main load-bearing structure, used to support the pole-mounted circuit breaker and other power distribution equipment on the distribution pole, providing a stable installation foundation for the equipment. The "anti-wind deflection function" is the core innovation of this solution. Relying on the first and second sets of damping rods arranged in a cross pattern, they restrain each other at the intersection point when the wind load impacts and alternately provide restoring force to complete the first stage of vibration reduction. Then, the hinge ball at the end of the deformable hinge shaft achieves multi-directional adaptive deflection in the ball groove of the fixed ball to complete the second stage of vibration reduction. At the same time, the tension rod tensions the movable ring and the fixed ring to keep the upper end of the support mechanism in a stable stress state. Thus, in the strong wind environment, it effectively offsets the impact of wind load on the bracket and the installed equipment, avoiding equipment deviation, shaking, or even phase-to-phase short circuit and other operational failures.

[0003] Existing pole-mounted circuit breaker mounting brackets mostly adopt a structure combining fixed-size clamps and rigid support rods. In actual use, there are two prominent problems: First, the diameter of the poles erected in different areas varies. Traditional clamps need to be matched with the pole size by replacing the corresponding bolts or adding shims, making the adjustment process at height cumbersome, time-consuming, and labor-intensive. Second, in strong wind environments, rigid brackets cannot buffer wind-induced vibrations. The self-overlapping of the equipment and the wind load can easily cause continuous swaying and tilting at the upper end of the bracket. Long-term operation can easily lead to loosening of fasteners, which in severe cases can cause damage to the circuit breaker terminals due to pulling force, or even cause line tripping faults. To address these problems, a pole-mounted circuit breaker mounting bracket with anti-wind deflection function is proposed. Summary of the Invention

[0004] To overcome the above shortcomings, this invention provides a pole-mounted circuit breaker mounting bracket with anti-wind deflection function, aiming to improve the problems of existing pole-mounted circuit breaker mounting brackets being cumbersome to operate when adapting to poles of different diameters, and prone to swaying and deflection under wind load, which affects operational reliability.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A pole-mounted circuit breaker mounting bracket with wind deflection prevention function includes an experimental column for support, and a support mechanism is installed on the surface of the experimental column.

[0007] The support mechanism includes a first set of arc plates for load-bearing. A first set of U-shaped fixing frames is installed at the lower ends of both sides of each pair of arc plates. A second set of U-shaped fixing frames is vertically installed on the first set of U-shaped fixing frames. Two sets of U-shaped movable frames are installed on the sides of the first set of U-shaped fixing frames that are far apart from each other. A first set of damping rods is installed in the middle of the first set of U-shaped fixing frames and the U-shaped movable frames. Two sets of deformable hinge shafts for the front and rear tubes are installed on the side of the first set of damping rods closest to the U-shaped movable frames. Two fixed spheres are installed at the ends of the two sets of deformable hinge shafts that are close to each other. A second set of damping rods is installed inside the second set of U-shaped fixing frames. Multiple V-shaped support bars are installed at the ends of the second set of damping rods that are far away from the second set of U-shaped fixing frames. The upper surfaces of the front and rear ends of the outermost V-shaped support bars are fixedly connected to the top of the U-shaped fixing frames by rivets.

[0008] As a further description of the above technical solution: a second set of arc plates is provided at the upper end of the first set of arc plates, and two sets of fixing rings are installed on each of the second set of arc plates away from each other at the middle of the side wall and at the upper end of the two fixed spheres.

[0009] As a further description of the above technical solution: two tension rods are installed in the middle of each set of fixed rings, and two sets of movable rings are hinged to the left and right ends of each tension rod.

[0010] As a further description of the above technical solution: slots are uniformly and vertically provided on the upper surface of the first group of arc plates and the lower surface of the second group of arc plates. Two arc tensioning plates are provided inside the first group of arc plates and the second group of arc plates. Reinforcing ribs are vertically arranged at equal intervals on the upper surface of each arc tensioning plate.

[0011] As a further description of the above technical solution: the shape of the slot is matched with the arc tensioning plate and the reinforcing rib. By selectively inserting the arc tensioning plate and the reinforcing rib into different slots, the first set of arc plates and the second set of arc plates can be freely adapted to experimental columns of different diameters, while enhancing the radial clamping force and eliminating the cumbersome operation of replacing bolts of different sizes or adding shims required by traditional clamps.

[0012] As a further description of the above technical solution: the first set of damping rods and the second set of damping rods are connected near the first set of U-shaped fixing frames and the second set of U-shaped fixing frames by two sets of locking bolts. The first set of damping rods and the second set of damping rods are installed crosswise. Through the mutual restraint and rebound force compensation of the first set of damping rods and the second set of damping rods at the intersection point, the two sets of damping rods alternately provide restoring force when subjected to wind load impact, thereby achieving the first vibration reduction and buffering treatment of wind-induced vibration.

[0013] As a further description of the above technical solution: each of the two sets of deformable hinge shafts has a hinge ball connected to one end of each pair of opposite ends. The front and rear sides of the two fixed spheres are provided with ball grooves that match the hinge balls. The hinge balls are embedded in the ball grooves to form a spherical pair fit, so that the deformable hinge shaft and the fixed sphere can achieve adaptive angle deflection in multiple directions, thereby further damping and buffering the residual wind vibration energy through the second adaptation deformation.

[0014] As a further description of the above technical solution: multiple V-shaped support bars are installed at equal intervals along the front-back direction at one end of the second set of damping rods near the U-shaped movable frame. The V-shaped cross-section structure of the V-shaped support bars makes its bending strength higher than that of a flat plate structure of the same mass. By arranging multiple V-shaped support bars along the axial direction, a continuous support plane can be formed on the top of the multiple V-shaped support bars for direct installation of pole-mounted switchgear or other power distribution equipment.

[0015] As a further description of the above technical solution: the two sets of movable rings are hinged to the two sets of fixed rings, and the movable rings can rotate or slide freely on the fixed rings; the movable rings and fixed rings are connected by the tension rod, and under the tension of the tension rod, the upper end of the entire support mechanism is kept in a stable stress state, preventing the upper end from swaying or tilting due to wind load or the weight of the equipment.

[0016] As a further description of the above technical solution: two sets of connecting ears are installed on the lower surface of the first set of arc plates and the lower surface of the second set of arc plates. The two sets of connecting ears are arc-shaped, and the outer ring surface of the two sets of connecting ears is provided with an installation port.

[0017] The present invention has the following beneficial effects:

[0018] 1. In this invention, by selectively inserting the arc tensioning plate and reinforcing rib into slots at different positions of the first and second sets of arc plates, the inner arc surface of the arc tensioning plate is tightly fitted to the outer wall of the experimental column. This enables the operation of quickly adapting to experimental columns of different diameters without replacing bolts or adding shims, while also enhancing the radial clamping force and greatly simplifying the installation process.

[0019] 2. In this invention, the first and second sets of damping rods, arranged in a cross pattern, restrain each other at the intersection point and alternately provide restoring force when subjected to wind load impact, thus completing the first damping buffer against wind-induced vibration. Then, the multi-directional adaptive deflection of the hinge ball at the end of the deformable hinge shaft within the groove of the fixed ball completes the second damping buffer against residual wind vibration energy. At the same time, the tension rod is used to tension the movable ring and the fixed ring to keep the upper end of the support mechanism in a stable force state, thereby effectively suppressing wind-induced swaying and deflection and ensuring the operational reliability of the pole-mounted circuit breaker.

Detailed Implementation

[0029] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0030] Reference Figures 1-7The present invention provides an embodiment of a pole-mounted circuit breaker mounting bracket with wind-resistant deflection function:

[0031] A pole-mounted circuit breaker mounting bracket with wind deflection prevention function includes an experimental column 1 for supporting the circuit, and a support mechanism 2 is installed on the surface of the experimental column 1.

[0032] As a further improvement to the above technical solution: the support mechanism 2 includes a first set of arc plates 201 for load-bearing; a first set of U-shaped fixing frames 202 are installed at the lower ends of both the front and rear sides of each pair of the first set of arc plates 201; a second set of U-shaped fixing frames 203 are vertically installed on the first set of U-shaped fixing frames 202; two sets of U-shaped movable frames 204 are installed on the sides of the first set of U-shaped fixing frames 202 that are far apart from each other; and a first set of damping rods 205 are installed in the middle of the first set of U-shaped fixing frames 202 and U-shaped movable frames 204. The first set of damping rods 205 is equipped with two sets of deformable hinge shafts 206 for the front and rear tubes on one side near the U-shaped movable frame 204. Two fixed balls 207 are installed at the ends of the two sets of deformable hinge shafts 206 that are close to each other. The second set of damping rods 208 is installed inside the second set of U-shaped fixed frame 203. Multiple V-shaped support bars 209 are installed at the end of the second set of damping rods 208 away from the second set of U-shaped fixed frame 203. The upper surfaces of the front and rear ends of the outermost V-shaped support bar 209 are fixedly connected to the top of the U-shaped fixed frame by rivets.

[0033] The upper end of the first set of arc plates 201 is provided with a second set of arc plates 210. The second set of arc plates 210 are each equipped with two sets of fixing rings 211 at the upper ends of the two fixed spheres 207 and at the center of the side wall.

[0034] Two tension rods 212 are installed in the middle of each set of fixed rings 211, and two sets of movable rings 213 are hinged to the left and right ends of each tension rod 212.

[0035] Slots 214 are uniformly and vertically provided on the upper surface of the first set of arc plates 201 and the lower surface of the second set of arc plates 210. Two arc tensioning plates 215 are provided inside the first set of arc plates 201 and the second set of arc plates 210. Reinforcing ribs 216 are arranged vertically and equidistantly on the upper surface of each arc tensioning plate.

[0036] The shape of the slot 214 is matched with the arc tensioning plate 215 and the reinforcing rib 216. By selectively inserting the arc tensioning plate 215 and the reinforcing rib 216 into different slots 214, the first set of arc plates 201 and the second set of arc plates 210 can be freely adapted to experimental columns 1 of different diameters, while enhancing the radial clamping force and eliminating the cumbersome operation of replacing bolts of different sizes or adding washers required by traditional clamps.

[0037] The first set of damping rods 205 and the second set of damping rods 208 are connected near the first set of U-shaped fixing frames 202 and the second set of U-shaped fixing frames 203 by two sets of locking bolts 217. The first set of damping rods 205 and the second set of damping rods 208 are installed crosswise. Through the mutual restraint and rebound force compensation of the first set of damping rods 205 and the second set of damping rods 208 at the intersection point, the two sets of damping rods alternately provide restoring force when subjected to wind load impact, thereby achieving the first vibration reduction and buffering treatment of wind-induced vibration.

[0038] Each of the two sets of deformable hinge shafts 206 has a hinge ball 218 connected to one end of each pair of opposite ends. The two fixed balls 207 have ball grooves on their front and rear sides that match the hinge balls 218. The hinge balls 218 are embedded in the ball grooves to form a spherical pair fit, so that the deformable hinge shafts 206 and the fixed balls 207 can achieve adaptive angle deflection in multiple directions, thereby further damping and buffering the residual wind vibration energy through the second adaptation deformation.

[0039] Multiple V-shaped support bars 209 are installed at equal intervals along the front-to-back direction at one end of the second set of damping rods 208 near the U-shaped movable frame 204. The V-shaped cross-section structure of the V-shaped support bars 209 makes its bending strength higher than that of a flat plate structure of the same mass. By arranging multiple V-shaped support bars 209 along the axial direction, a continuous support plane can be formed on the top of the multiple V-shaped support bars 209 for direct installation of pole-mounted switchgear or other power distribution equipment.

[0040] The two sets of movable rings 213 are hinged to the two sets of fixed rings 211. The movable rings 213 can rotate or slide freely on the fixed rings 211. The movable rings 213 and fixed rings 211 are connected by the tension rod 212. Under the tension of the tension rod 212, the upper end of the entire support mechanism 2 is kept in a stable stress state, preventing the upper end from swaying or tilting due to wind load or the weight of the equipment.

[0041] Specifically, by fastening the first set of arc plates 201 and the second set of arc plates 210 to the upper and lower ends of the outer periphery of the experimental column 1 respectively, and using the slots 214 that are evenly and vertically opened on the upper surface of the first set of arc plates 201 and the lower surface of the second set of arc plates 210, the arc tensioning plate 215 together with the reinforcing ribs 216 arranged at equal intervals on its surface are inserted into the corresponding slots 214, so that the inner arc surface of the arc tensioning plate 215 is tightly attached to the outer wall of the experimental column 1, thereby achieving the purpose of quickly adapting to experimental columns 1 of different diameters.

[0042] The selective insertion method of the arc tensioning plate 215 and the reinforcing rib 216 into different slots 214, and the design of matching the shape of the slot 214 with the contour of the arc tensioning plate 215 and the reinforcing rib 216, allows the operator to adjust the radial clamping force without replacing bolts or adding shims, thereby simplifying the installation process and improving on-site construction efficiency.

[0043] By installing the first set of U-shaped fixed frames 202 on the lower front and rear sides of the first set of arc plates 201 on opposite sides, and vertically connecting the second set of U-shaped fixed frames 203 below the first set of U-shaped fixed frames 202, and then installing the two sets of U-shaped movable frames 204 on the opposite sides of the first set of U-shaped fixed frames 202, the two ends of the first set of damping rods 205 are respectively mounted on the middle of the first set of U-shaped fixed frames 202 and U-shaped movable frames 204, thereby achieving the purpose of establishing a vibration damping support frame.

[0044] Two sets of deformable hinge shafts 206 are respectively installed on one side of the first set of damping rods 205 near the U-shaped movable frame 204. A fixed ball 207 is installed at each end of the two sets of deformable hinge shafts 206 that are close to each other. The hinge ball 218 at the end of the deformable hinge shaft 206 is embedded in the ball groove of the fixed ball 207 to form a spherical pair fit. In this way, when subjected to wind load impact, it can achieve multi-directional adaptive angle deflection and achieve the purpose of consuming residual wind vibration energy.

[0045] By installing the second set of damping rods 208 inside the second set of U-shaped fixing frames 203, and installing multiple V-shaped support bars 209 arranged at equal intervals along the front-back direction at the end of the second set of damping rods 208 away from the second set of U-shaped fixing frames 203, and fixing the upper surfaces of the front and back ends of the outermost V-shaped support bars 209 to the top of the U-shaped fixing frame with rivets, the tops of the multiple V-shaped support bars 209 form a continuous support plane, thereby achieving the purpose of directly installing pole-mounted switchgear or other power distribution equipment.

[0046] The first set of damping rods 205 and the second set of damping rods 208 are installed in a cross manner. The damping rods are fixed to the first set of U-shaped fixing frames 202 and the second set of U-shaped fixing frames 203 respectively by two sets of locking bolts 217. This makes the two sets of damping rods mutually restrain each other at the intersection point, so that they can alternately provide restoring force when subjected to wind load impact, thereby achieving the purpose of first-stage vibration reduction and buffering treatment for wind-induced vibration.

[0047] By installing two sets of fixed rings 211 on the middle of the second set of arc plates 210, which are far from each other and on the upper end of the two fixed spheres 207, and by using two tension rods 212 installed in the middle of each fixed ring 211, and by hinged a set of movable rings 213 to each end of the tension rods 212, the movable rings 213 and the fixed rings 211 form a hinged relationship that can rotate or slide freely. Thus, under the tension of the tension rods 212, the upper end of the entire support mechanism 2 is kept in a stable stress state, thereby preventing the upper end from swaying or tilting due to wind load or the weight of the equipment.

[0048] As a further improvement to the above technical solution: two sets of connecting ears 3 are installed on the lower surface of the first set of arc plates 201 and the lower surface of the second set of arc plates 210. The two sets of connecting ears 3 are arc-shaped, and the outer ring surface of the two sets of connecting ears 3 is provided with an installation port.

[0049] Specifically, by installing two sets of connecting ears 3 on the lower surfaces of the first set of arc plates 201 and the second set of arc plates 210 respectively, the arc-shaped outer ring surface of the connecting ear 3 is smoothly attached to the outer arc surface of the arc plate, so that a stable connection structure with surface contact is formed between the connecting ear 3 and the arc plate, thereby avoiding stress concentration and extending the service life of the connection part.

[0050] The mounting port on the outer ring of the connecting ear 3 is designed to match the size of the standard fastening bolt, allowing operators to directly insert the bolt into the mounting port for tightening without the need for on-site modification or additional processing, thus achieving rapid disassembly and maintenance.

[0051] By symmetrically distributing two sets of connecting ears 3 on the lower surfaces of the first set of arc plates 201 and the second set of arc plates 210, the symmetrical arrangement of forces ensures that the upper and lower sets of arc plates are subjected to balanced forces during locking, thereby avoiding the skew phenomenon caused by unilateral locking and achieving the purpose of ensuring the overall coaxiality and stability of the support mechanism 2.

[0052] By using the method of integral molding or welding the connecting ear 3 with the arc plate, the arc-shaped contour of the connecting ear 3 itself is used to disperse the local pressure during locking, so that the fastening force is evenly transmitted to the entire contact surface of the arc plate, thereby enhancing the uniformity of the radial clamping force and achieving the purpose of improving the overall rigidity of the bracket.

[0053] Working principle: The installer first fastens the first set of arc plates 201 and the second set of arc plates 210 onto the outer periphery of the experimental column 1. According to the actual diameter of the experimental column 1, the corresponding slot 214 is selected. The arc tensioning plate 215, together with its surface reinforcing ribs 216, is inserted into the slot 214, so that the inner arc surface of the arc tensioning plate 215 is tightly attached to the outer wall of the experimental column 1. Then, the relative fixation of the first set of arc plates 201 and the second set of arc plates 210 is completed through the mounting holes 4 on the connecting ear 3. Thus, it is possible to quickly adapt to experimental columns 1 of different diameters without replacing bolts of different specifications or adding washers.

[0054] When strong winds occur outdoors, the wind load first acts on the equipment mounting plane at the top of the V-shaped support bar 209. The impact force is transmitted through the V-shaped support bar 209 to the second set of damping rods 208. The first set of damping rods 205 and the second set of damping rods 208, which are arranged in a cross pattern, restrain each other at the intersection point. They deform through their internal elastic elements and alternately provide restoring force, thereby completing the first-level buffering of wind vibration energy. The residual impact force continues to be transmitted along the first set of damping rods 205 to the deformable hinge shaft 206. The hinge ball 218 at the end of the deformable hinge shaft 206 achieves multi-directional adaptive angle deflection in the ball groove of the fixed ball 207. The flexible deformation of the structure further consumes the residual wind vibration energy, thereby completing the second-level buffering. At the same time, the movable rings 213 at both ends of the tension rod 212 adaptively rotate or slide on the fixed ring 211, always applying a continuous tension force to the upper structure of the support, thereby offsetting the skew torque caused by the equipment's own weight and the wind load, so that the upper end of the entire support mechanism 2 always maintains a stable stress state.

[0055] 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.
