Description

Technical Field

[0001] This invention relates to the field of electrical equipment technology, and in particular to a primary and secondary integrated pole-mounted circuit breaker. Background Technology

[0002] A pole-mounted circuit breaker integrating primary and secondary circuits is a type of electrical equipment that integrates primary equipment (such as switches and circuit breakers) and secondary equipment (such as control systems, protection devices, and measuring instruments) into one unit. It is typically installed on power poles and is widely used in high-voltage power systems, playing a particularly important role in the automation, remote control, protection, and monitoring of distribution networks.

[0003] The prior art publication CN118899190A provides a novel integrated primary and secondary pole-mounted circuit breaker. When the tripping mechanism is unlocked by the operation mechanism, the tripping elastic element drives the slide to move. The high-speed rotation of the centrifugal element in the deceleration assembly causes multiple friction elements placed inside the centrifugal element to undergo centrifugal motion. Combined with the action of the lifting elastic element, the lock cylinder is pushed away from the centrifugal chamber. The contact area between the lock cylinder and the friction elements gradually decreases until they are completely separated. During the process of the rotating push rod of the friction disc sliding from the first position through the release channel to the second position, the push rod is pushed back into the centrifugal chamber and the distance between the lock cylinder and the friction elements is gradually reduced until they contact each other. This achieves the deceleration of the centrifugal element until it locks the centrifugal element to rotate. After the centrifugal element locks, the slide locks synchronously, thereby achieving buffering of the tripping process, reducing the impact of the slide on the internal components of the housing and protecting the internal components.

[0004] Existing integrated primary and secondary pole-mounted circuit breakers are commonly used in power distribution networks, especially on high-voltage distribution lines, to protect lines from overloads, short circuits, and other faults. They are typically installed on the poles of the distribution lines, hence the name "pole-mounted circuit breaker." Because the circuit breaker is mounted on the pole, the operating handle is in a high position. For ordinary operators, manual operation may require the use of ladders or other tools, increasing the difficulty and inconvenience of operation.

[0005] In summary, the existing technology lacks a technique for operating the control handle of a primary and secondary integrated pole-mounted circuit breaker using a rope. Summary of the Invention

[0006] The purpose of this invention is to address the shortcomings of the prior art by proposing a primary and secondary integrated pole-mounted circuit breaker.

[0007] To achieve the above objectives, the technical solution adopted by the present invention is as follows: a primary and secondary integrated pole-mounted circuit breaker, comprising a circuit breaker body, an operating handle installed on one side of the circuit breaker body, a take-up seat fixedly connected to both ends of the operating handle, a winding shaft rotatably connected inside the take-up seat, a steel wire rope wound and fixedly mounted on the winding shaft, a protective cover movably inserted into one side of the take-up seat, an air extraction seat fixedly connected to the other side of the take-up seat, a fixing frame fixedly connected to the take-up seat, and a transmission mechanism rotatably connected to the fixing frame.

[0008] Preferably, an annular groove is provided on one side of the outer end of the take-up seat, a positioning hole is provided on the outer wall of the bottom end of the take-up seat, an air guide groove is provided on the inner wall of the bottom end of the take-up seat, and a plurality of air jet holes are provided through the air guide groove and the positioning hole, and the air jet holes are arranged in a conical inclined structure.

[0009] Preferably, one end of the winding spool extends through the inner wall of the take-up seat to the outside and is fixedly connected to a motor. The motor is fixedly connected to the outer wall of the take-up seat. A protruding disc is fixedly connected to one end of the winding spool near the motor, and an annular rack is fixedly connected to the other end of the winding spool.

[0010] Preferably, the free end of the wire rope extends through the inner wall of the take-up seat to the outside and is fixedly connected to a handle, the top of the handle being movably inserted into the positioning hole.

[0011] Preferably, the protective cover is provided with a plurality of plug rods that slide together. One end of each plug rod is movably plugged into the inner wall of the annular groove, and the other end of each plug rod is fixedly connected to a pressing rod. A spring is fixedly connected to one side of the pressing rod, and the other end of the spring is fixedly connected to the protective cover.

[0012] Preferably, one end of the suction seat is fixedly connected to an air guide pipe, which is fixedly connected to the take-up seat. One end of the air guide pipe communicates with the inner wall of the air guide groove. A universal joint A is rotatably connected to the air guide pipe. One end of the universal joint A extends through the outer wall of the take-up seat and is fixedly connected to a drive wheel. The drive wheel meshes with a ring rack for transmission. The other end of the universal joint A extends into the suction seat and is fixedly connected to a fan blade. A semi-circular filter screen is fixedly connected to the opening of the suction seat.

[0013] Preferably, a photovoltaic panel is fixedly installed at the bottom of the fixed frame, and a movable frame is slidably fitted on the inner wall of the bottom of the fixed frame. Multiple tension springs are fixedly connected to one side of the movable frame, and the other end of the tension springs is fixedly connected to the fixed frame. A wiping strip is fixedly connected to the movable frame, and the wiping strip is slidably in contact with the surface of the photovoltaic panel.

[0014] Preferably, the transmission mechanism includes a universal joint B, which is rotatably connected to the fixed frame. One end of the universal joint B passes through the fixed frame and is fixedly connected to a push rod assembly. The other end of the push rod assembly is rotatably connected to the wiping strip. An adjusting wheel is fixedly connected to the other end of the universal joint B.

[0015] Preferably, an adjusting rack is slidably fitted on one side of the adjusting wheel, and a sliding rod is fixedly connected to the adjusting rack. The sliding rod is slidably fitted through the inner wall of the take-up seat, and a contact wheel is rotatably connected to one end of the sliding rod inside the take-up seat. The contact wheel is slidably in contact with the outer wall of the raised disc.

[0016] Compared with the prior art, the present invention has the following beneficial effects:

[0017] 1. By installing steel wire ropes at both ends of the operating handle, the handle connected to the steel wire rope can be raised and lowered using a reel. When manual control of the operating handle is required, the operator does not need to directly touch the handle. This is especially useful when the utility pole is high or inaccessible. The operator can operate by pulling the steel wire rope, which improves the convenience of operation, avoids the need to climb or use ladders, effectively avoids the risks of working at height, reduces the chance of personnel coming into contact with electrical parts, and allows the operator to maintain a safe operating distance by remotely pulling the steel wire rope, thereby reducing danger.

[0018] 2. By driving the wire rope into the take-up seat while the winding shaft drives the fan blades in the air extraction seat to rotate, the air jet can spray out flowing air, which can effectively treat the rainwater adhering to the surface of the wire rope in rainy weather. Moisture, dirt and other impurities adhering to the wire rope may accelerate its aging and corrosion. By using flowing air to blow them away, the surface of the wire rope can be kept clean, reducing the risk of corrosion and extending the service life of the wire rope.

[0019] 3. By installing photovoltaic panels on a fixed frame and using the rotation of the winding shaft to drive the wiping strip, automated cleaning can be achieved, improving the working efficiency of the photovoltaic panels, extending equipment life, reducing maintenance costs, and improving equipment stability and reliability. At the same time, the photovoltaic panels provide driving force for the rotation of the winding shaft, giving the device advantages such as environmental protection, energy saving, and intelligent management.

[0029] The following description is intended to disclose the invention and enable those skilled in the art to implement it. The preferred embodiments described below are merely examples, and other obvious variations will occur to those skilled in the art.

[0030] like Figures 1-8 The illustrated primary and secondary integrated pole-mounted circuit breaker includes a circuit breaker body 1. An operating handle 2 is installed on one side of the circuit breaker body 1. Both ends of the operating handle 2 are fixedly connected to a take-up seat 3. A winding shaft 4 is rotatably connected inside the take-up seat 3. A steel wire rope 5 is wound and fixedly installed on the winding shaft 4. A protective cover 6 is movably inserted into one side of the take-up seat 3. An air extraction seat 7 is fixedly connected to the other side of the take-up seat 3. A fixing frame 8 is fixedly connected to the take-up seat 3. A transmission mechanism 9 is rotatably connected to the fixing frame 8.

[0031] like Figure 3 As shown, an annular groove 301 is formed on one side of the outer end of the take-up base 3, a positioning hole 302 is formed on the outer wall of the bottom end of the take-up base 3, and an air guide groove 303 is formed on the inner wall of the bottom end of the take-up base 3. Multiple air jet holes 304 are formed through the air guide groove 303 and the positioning hole 302. The air jet holes 304 are set in a conical inclined structure. The conical inclined structure of the air jet holes 304 can make the air blow downward, thereby improving the moisture removal effect.

[0032] like Figure 4 As shown, one end of the winding spool 4 extends through the inner wall of the take-up seat 3 to the outside and is fixedly connected to a motor 401. The motor 401 is fixedly connected to the outer wall of the take-up seat 3. A protruding disc 402 is fixedly connected to one end of the winding spool 4 near the motor 401, and an annular rack 403 is fixedly connected to the other end of the winding spool 4.

[0033] like Figure 4 As shown, the free end of the wire rope 5 extends through the inner wall of the take-up seat 3 to the outside and is fixedly connected to a handle 501. The top of the handle 501 is movably inserted into the positioning hole 302.

[0034] By installing steel wire ropes 5 at both ends of the operating handle 2, the pull handle 501 connected to the steel wire ropes can be raised and lowered using the reel 4. When manual control of the operating handle 2 is required, the operator does not need to directly contact the operating handle 2. This is especially useful when the power pole is high or difficult to access. The operator can operate by pulling the steel wire rope 5, which improves the convenience of operation, avoids the need to climb or use ladders, effectively avoids the risks of working at height, reduces the chance of personnel coming into contact with electrical parts, and allows the operator to maintain a safe operating distance by remotely pulling the steel wire rope 5, thereby reducing danger.

[0035] like Figure 5 As shown, multiple plug-in rods 601 are slidably fitted onto the protective cover 6. One end of each plug-in rod 601 is movably inserted into the inner wall of the annular groove 301, and the other end of each plug-in rod 601 is fixedly connected to a pressing rod 602. A spring 603 is fixedly connected to one side of the pressing rod 602, and the other end of the spring 603 is fixedly connected to the protective cover 6. When inspecting the motor 401, hold one end of the protective cover 6. This will squeeze the multiple pressing rods 602, causing the plug-in rods 601 connected to the pressing rods 602 to move out of the annular groove 301, allowing the protective cover 6 to be removed. After inspection, insert one end of the protective cover 6 into the take-up seat 3, and then release the pressing rod 602. Under the action of the spring 603, the plug-in rod 601 is inserted into the annular groove 301 for limiting.

[0036] like Figure 6As shown, an air extraction base 7 has an air guide pipe 701 fixedly connected to one end, and the air guide pipe 701 is fixedly connected to the take-up base 3. One end of the air guide pipe 701 is connected to the inner wall of the air guide groove 303. A universal joint A702 is rotatably connected to the air guide pipe 701. One end of the universal joint A702 extends through the outer wall of the take-up base 3 and is fixedly connected to the drive wheel 703. The drive wheel 703 meshes with the ring rack 403 for transmission. The other end of the universal joint A702 extends into the air extraction base 7 and is fixedly connected to the fan blade 704. A semi-circular filter screen 705 is fixedly connected to the opening of the air extraction base 7. When the winding shaft 4 rotates, it will drive the connected annular rack 403 to rotate. At this time, the annular rack 403 will drive the universal joint A702 connected to the transmission wheel 703 to rotate, so that the universal joint A702 can drive the connected fan blade 704 to rotate. At this time, the external air is filtered through the semi-circular filter screen 705 and injected into the air guide groove 303 through the air guide pipe 701, and then ejected through the jet hole 304.

[0037] like Figure 7 As shown, a photovoltaic panel 801 is fixedly mounted on the bottom of the fixed frame 8. A movable frame 802 is slidably fitted onto the inner wall of the bottom of the fixed frame 8. Multiple tension springs 803 are fixedly connected to one side of the movable frame 802, and the other end of each tension spring 803 is fixedly connected to the fixed frame 8. A wiping adhesive strip 804 is fixedly connected to the movable frame 802, and the wiping adhesive strip 804 slides in contact with the surface of the photovoltaic panel 801. Under the action of the tension springs 803, the wiping adhesive strip 804 connected to the movable frame 802 will automatically reset.

[0038] like Figure 8 As shown, the transmission mechanism 9 includes a universal joint B901, which is rotatably connected to the fixed frame 8. One end of the universal joint B901 passes through the fixed frame 8 and is fixedly connected to a push rod assembly 902. The other end of the push rod assembly 902 is rotatably connected to the wiping strip 804. An adjusting wheel 903 is fixedly connected to the other end of the universal joint B901.

[0039] An adjusting rack 904 is slidably fitted on one side of the adjusting wheel 903. A sliding rod 905 is fixedly connected to the adjusting rack 904. The sliding rod 905 is slidably fitted through the inner wall of the take-up seat 3. A contact wheel 906 is rotatably connected to one end of the sliding rod 905 inside the take-up seat 3. The contact wheel 906 is in slidable contact with the outer wall of the raised disc 402. When the winding shaft 4 rotates, it drives the connected raised disc 402 to rotate. At this time, the raised disc 402 contacts and presses the contact wheel 906, causing the sliding rod 905 connected to the contact wheel 906 to move. This allows the adjusting rack 904 on the sliding rod 905 to drive the universal joint B901 connected to the adjusting wheel 903 to rotate. The universal joint B901 then drives the connected push rod assembly 902 to rotate, causing the push rod assembly 902 to move the wiping strip 804.

[0040] Working principle: When manual control of the operating handle 2 is required, the motor 401 at one end of the operating handle 2 will drive the connected winding shaft 4 to rotate according to the opening and closing requirements. At this time, the handle 501 will drive the connected steel wire rope 5 to move down, so that the handle 501 will drop to a suitable height for easy manual operation.

[0041] Simultaneously, when the winding shaft 4 rotates, it will drive the connected protruding disc 402 to rotate. At this time, the protruding disc 402 will contact and squeeze the contact wheel 906, causing the sliding rod 905 connected to the contact wheel 906 to move. This allows the adjusting rack 904 on the sliding rod 905 to drive the universal joint B901 connected to the adjusting wheel 903 to rotate. This allows the universal joint B901 to drive the connected push rod assembly 902 to rotate. This allows the push rod assembly 902 to drive the wiping strip 804 to move and wipe the surface of the photovoltaic panel 801. Then, under the action of the tension spring 803, the wiping strip 804 connected to the movable frame 802 will automatically reset.

[0042] After the operation handle 2 is finished, the winding shaft 4 rotates in the opposite direction, which drives the handle 501 connected to the wire rope 5 to reset, so that the top of the handle 501 is inserted into the positioning hole 302 for fixing.

[0043] At the same time, when the winding shaft 4 rotates, it will drive the connected ring rack 403 to rotate. At this time, the ring rack 403 will drive the universal joint A702 connected to the transmission wheel 703 to rotate, so that the universal joint A702 can drive the connected fan blade 704 to rotate. At this time, the external air is filtered through the semi-circular filter screen 705 and injected into the air guide groove 303 through the air guide pipe 701, and sprayed out through the jet hole 304 to clean the rainwater adhering to the surface of the wire rope 5 in rainy weather.

[0044] When the motor 401 needs to be inspected, hold one end of the protective cover 6. This will squeeze multiple pressing rods 602, causing the plug rod 601 connected to the pressing rod 602 to move out of the annular groove 301, so that the protective cover 6 can be removed. After the inspection is completed, insert one end of the protective cover 6 into the take-up seat 3, and then release the pressing rod 602. Under the action of the spring 603, the plug rod 601 is inserted into the annular groove 301 for limiting.
