Description

Technical Field

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

[0002] With the continuous development of smart grids, integrated pole-mounted circuit breakers, which combine primary and secondary circuits, have been widely used in overhead power distribution lines due to their efficient control, protection, and monitoring functions. However, existing pole-mounted circuit breaker connection devices have many problems. For example, the installation process of some connection devices is complicated and requires a lot of manpower and time, which is extremely unfavorable for work scenarios that require rapid line erection or maintenance. Some connection devices perform poorly in terms of electrical connection stability and are easily affected by external environmental factors (such as wind and vibration), resulting in poor contact and thus affecting the normal operation of the power system. In addition, some connection devices have poor versatility and are difficult to adapt to different specifications and models of pole-mounted circuit breakers and related power equipment, which limits their application scope.

[0003] Regarding the above-mentioned and existing related technologies, the inventors believe that the following defects often exist: because the dimensions of the parts connecting the circuit breaker body and the support frame are fixed in the traditional method, the circuit breaker body cannot flexibly adapt to support frames of different sizes according to the actual installation environment. It may be impossible to install due to size mismatch with the support frame, thereby reducing the installation efficiency of the circuit breaker body and delaying the project progress. Therefore, in order to solve the above problems, a primary and secondary integrated pole-mounted circuit breaker connection device is proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, where the fixed size of the parts connecting the circuit breaker body and the support frame makes it impossible for the circuit breaker body to flexibly adapt to different sizes of support frames according to the actual installation environment. This may result in the circuit breaker body being unable to be installed due to size mismatch with the support frame, thereby reducing the installation efficiency of the circuit breaker body and delaying the project progress. Therefore, this utility model proposes a primary and secondary integrated pole-mounted circuit breaker connection device.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a primary and secondary integrated pole-mounted circuit breaker connection device, comprising a circuit breaker body, a clamping device provided on the surface of the circuit breaker body, the clamping device comprising two square frames, both square frames being fixedly connected to the surface of the circuit breaker body, an isolation plate being fixedly connected to the inner surface of both square frames, two U-shaped compartments being slidably connected to the inner surface of the square frames, a connecting frame being slidably connected to the inner surface of both U-shaped compartments, four fixing plates being fixedly connected to the surface of the square frames, and screws being threadedly inserted into the four fixing plates, a plurality of screw grooves being opened on the surface of the U-shaped compartments, and the screws being threadedly connected to the inner wall of the screw grooves of the U-shaped frames.

[0006] The effect achieved by the above-mentioned components is that by setting up a clamping device, the circuit breaker body can be clamped and fixed on the surface of support frames of different sizes. This avoids the situation where the size of the parts connecting the circuit breaker body and the support frame is fixed in the traditional way, which makes it impossible for the circuit breaker body to flexibly adapt to different sizes of support frames according to the actual installation environment. It may also prevent installation due to mismatch with the size of the support frame, thereby reducing the installation efficiency of the circuit breaker body and delaying the project progress.

[0007] Preferably, two first springs are fixedly connected to the surface of the isolation plate, and the other ends of the two first springs are fixedly connected to the U-shaped compartment.

[0008] The effect achieved by the above components is that the first spring is elastic. When the U-shaped frame is finished using, the stretched first spring automatically returns to its original position by its own elastic potential energy. This design eliminates the need for manual adjustment and significantly improves the ease of operation, allowing the U-shaped frame to quickly enter the next work cycle.

[0009] Preferably, the surface of the U-shaped frame is fixedly connected to two limiting plates, and each of the two limiting plates is threaded with a threaded rod. The surface of the connecting frame is provided with several threaded grooves, and the threaded rods are threadedly connected to the inner wall of the threaded grooves of the connecting frame.

[0010] The effect achieved by the above components is that the limiting plate and the threaded rod work together to limit the telescopic connecting frame.

[0011] Preferably, a rubber pad is fixedly connected to the surface of the connecting frame, and the size of the screw is adapted to the size of the U-shaped slot.

[0012] The effect achieved by the above components is that the relatively rough surface of the rubber pad increases the friction between the connecting frame and the support frame, making the connecting frame more firmly clamp the support frame, preventing relative slippage between the two, and ensuring the reliability of the circuit breaker body connection during operation.

[0013] Preferably, the surface of the circuit breaker body is provided with a shock-absorbing device, the shock-absorbing device includes two short rods, both of which are fixedly connected to the surface of the circuit breaker body, and the arc surfaces of the two short rods are slidably connected to a circular chamber, the inner surface of the circular chamber is fixedly connected to a second spring, and the other end of the second spring is fixedly connected to the short rod.

[0014] The effect achieved by the above-mentioned components is as follows: by setting up the shock absorption device, the shock absorption effect of the circuit breaker body is achieved, which avoids the alternating stress formed inside the circuit breaker body due to the impact and vibration suffered by the side during the operation of the circuit breaker body. The alternating stress will cause fatigue cracks in the metal structural components of the circuit breaker body. As time goes by, the cracks will expand and eventually may lead to the fracture of the structural components, causing the circuit breaker body to lose its mechanical support and protection functions.

[0015] Preferably, four edge plates are fixedly connected to the surface of the circuit breaker body, the four edge plates are grouped in pairs, and a middle plate is fixedly connected to the side of each pair of edge plates that is close to each other.

[0016] The effect achieved by the above components is that the edge plate and the middle plate work together to surround the cylinder, the second spring and the short rod, forming a relatively enclosed space that blocks rainwater and splashing water from all directions, reducing the chance of water directly contacting the second spring.

[0017] Preferably, a baffle plate is fixedly connected to the surface of the cylindrical container, and the size of the short rod is adapted to the size of the inner surface of the cylindrical container.

[0018] The aforementioned components achieve the following effects: the baffle can block stones, branches, and other objects flying from the front, preventing these objects from hitting the cylindrical chamber, preventing damage to the surface of the cylindrical chamber, protecting the structural integrity of the cylindrical chamber, and ensuring the safety of the second spring.

[0019] In summary, the beneficial effects of this utility model are as follows:

[0020] 1. In this utility model, by setting a clamping device, the circuit breaker body can be clamped and fixed on the surface of support frames of different sizes. This avoids the situation where the size of the parts connecting the circuit breaker body and the support frame is fixed in the traditional way, which makes it impossible for the circuit breaker body to flexibly adapt to support frames of different sizes according to the actual installation environment. It may be impossible to install due to mismatch with the size of the support frame, thereby reducing the installation efficiency of the circuit breaker body and delaying the project progress.

[0021] 2. In this utility model, by setting a shock-absorbing device, the shock absorption effect of the circuit breaker body is achieved, which avoids the alternating stress formed inside the circuit breaker body due to the impact and vibration suffered by the side during the operation of the circuit breaker body. The alternating stress will cause fatigue cracks in the metal structural parts of the circuit breaker body. As time goes by, the cracks will expand and eventually may lead to the fracture of the structural parts, causing the circuit breaker body to lose its mechanical support and protection functions.

[0029] Reference Figure 1 As shown, this utility model provides a technical solution: a primary and secondary integrated pole-mounted circuit breaker connection device, including a circuit breaker body 1. A clamping device 2 is provided on the surface of the circuit breaker body 1. By setting the clamping device 2, the circuit breaker body 1 can be clamped and fixed on the surface of support frames of different sizes. This avoids the situation where the dimensions of the parts connecting the circuit breaker body 1 and the support frame are fixed in traditional methods, preventing the circuit breaker body 1 from flexibly adapting to different sizes of support frames according to the actual installation environment. This could lead to installation failure due to size mismatch with the support frame, thus reducing the installation efficiency of the circuit breaker body 1 and delaying the project progress. A shock-absorbing device 3 is provided on the surface of the circuit breaker body 1. By setting the shock-absorbing device 3, the shock-absorbing effect of the circuit breaker body 1 is achieved, preventing the impact and vibration suffered by the side of the circuit breaker body 1 during operation from forming alternating stress inside the circuit breaker body 1. Alternating stress can cause fatigue cracks in the metal structural components of the circuit breaker body 1. Over time, the cracks will expand, eventually leading to structural component fracture and causing the circuit breaker body 1 to lose its mechanical support and protection functions.

[0030] The specific setup and function of the clamping device 2 and the shock absorption device 3 will be explained in detail below.

[0031] Reference Figure 2 , Figure 3 and Figure 4As shown in this embodiment: the clamping device 2 includes two square frames 201, both of which are fixedly connected to the surface of the circuit breaker body 1. Isolation plates 202 are fixedly connected to the inner surfaces of both square frames 201. Two U-shaped compartments 203 are slidably connected to the inner surfaces of both U-shaped compartments 203. Connecting frames 204 are slidably connected to the inner surfaces of both U-shaped compartments 203. Four fixing plates 205 are fixedly connected to the surface of the square frames 201. Screws 206 are threaded into each of the four fixing plates 205. Several threaded grooves are formed on the surface of the U-shaped compartments 203. The screws 206 are threaded into the inner walls of the threaded grooves of the U-shaped compartments. Two first springs 207 are fixedly connected to the surface of the isolation plates 202. The other ends of the two first springs 207 are fixedly connected to the U-shaped compartments 203. The first springs 207 are elastic. When the U-shaped compartments are no longer in use, the stretched first springs 207, due to their elastic potential energy... Automatic reset eliminates the need for manual adjustment, significantly improving operational convenience and allowing the U-shaped frame to quickly enter the next work cycle. Two limiting plates 20 are fixedly connected to the surface of the U-shaped frame, each with a threaded rod 209 threaded into it. Several threaded grooves are formed on the surface of the connecting frame 204, with the threaded rod 209 threaded into the inner wall of these grooves. The limiting plates 20 and the threaded rod 209 work together to limit the movement of the connecting frame 204. A rubber pad 210 is fixedly connected to the surface of the connecting frame 204. The size of the screw 206 matches the size of the threaded groove in the U-shaped compartment 203. The relatively rough surface of the rubber pad 210 increases the friction between the connecting frame 204 and the support frame, allowing the connecting frame 204 to more firmly clamp the support frame and preventing relative slippage, thus ensuring the reliability of the circuit breaker body 1 during operation.

[0032] Reference Figure 5 and Figure 6As shown, specifically, the shock absorption device 3 includes two short rods 31, both of which are fixedly connected to the surface of the circuit breaker body 1. A circular chamber 32 is slidably connected to the arc surface of each of the two short rods 31. A second spring 33 is fixedly connected to the inner surface of the circular chamber 32, and the other end of the second spring 33 is fixedly connected to the short rod 31. Four edge plates 34 are fixedly connected to the surface of the circuit breaker body 1. The four edge plates 34 are arranged in pairs, and a middle plate 35 is fixedly connected to the side of each pair of edge plates 34 closest to each other. The edge plates 34 and the middle plates 35 complement each other. The enclosure can surround the cylindrical chamber 32, the second spring 33, and the short rod 31 to form a relatively enclosed space, blocking rainwater and splashing water from all directions and reducing the chance of water directly contacting the second spring 33. A baffle plate 36 is fixedly connected to the surface of the cylindrical chamber 32. The size of the short rod 31 is adapted to the size of the inner surface of the cylindrical chamber 32. The baffle plate 36 can block stones, branches, etc. flying from the front, prevent these objects from hitting the cylindrical chamber 32, prevent damage to the surface of the cylindrical chamber 32, protect the structural integrity of the cylindrical chamber 32 and the safety of the second spring 33.

[0033] Working principle: When the operator needs to install the circuit breaker body 1 on the support frame, firstly, rotate the screw 206 backward until it disengages from the threaded groove on the surface of the U-shaped compartment 203. Then, pull the connecting frame 204 backward. The connecting frame 204 drives the U-shaped compartment 203 and the rubber pad 210 to move backward. During the backward movement of the U-shaped compartment 203, the first spring 207 is stretched until the connecting frame 204 is stretched out of the support frame surface. Then, the connecting frame 204 is released. At this time, the stretched first spring 207 will generate a rebound force, which will cause the rubber pad 210 and the connecting frame 204 to quickly rebound and press tightly against the surface of the support frame. Then, the screw 206 is rotated into the threaded groove of the U-shaped compartment 203 for fixation, clamping the circuit breaker body 1 onto the support frame. When it is necessary to clamp support frames of different sizes, first rotate the threaded rod 209 upward and disengage it from the threaded groove of the connecting frame 204. Then, stretch the connecting frame 204 outward until it is adjusted to the appropriate length. Then, rotate the threaded rod 209 downward until it is rotated into the threaded groove of the connecting frame 204. By setting the clamping device 2, the circuit breaker body 1 can be clamped and fixed on the surface of support frames of different sizes. This avoids the situation where the size of the parts connecting the circuit breaker body 1 and the support frame is fixed in the traditional way, which makes it impossible for the circuit breaker body 1 to flexibly adapt to support frames of different sizes according to the actual installation environment. It may be impossible to install due to mismatch with the size of the support frame, thereby reducing the installation efficiency of the circuit breaker body 1 and delaying the project progress.

[0034] When the side of the circuit breaker body 1 is impacted by an external force, it will first come into contact with the shield 36. The shield 36 can block stones, branches, etc. flying from the front. The shield 36 will move backward after being impacted. The backward movement of the shield 36 will drive the cylindrical chamber 32 to move. The cylindrical chamber 32 slides on the arc surface of the short rod 31 and compresses the second spring 33 backward. The second spring 33 has its own elasticity. During the compression process, it generates a reaction force and rebounds quickly, absorbing and buffering the impact force to reduce the damage to the circuit breaker body 1. During the operation of the circuit breaker body 1, the impact and vibration on the side will form alternating stress inside the circuit breaker body 1. The alternating stress will cause fatigue cracks in the metal structural components of the circuit breaker body 1. As time goes by, the cracks will expand and eventually may cause the structural components to break, causing the circuit breaker body 1 to lose its mechanical support and protection functions.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
