Description

Technical Field

[0001] This utility model relates to the field of vacuum circuit breaker technology, specifically to an IoT lighting vacuum circuit breaker with a protective structure. Background Technology

[0002] With the development of IoT technology and the steady advancement of national smart grid construction, users are ultimately choosing electrical equipment that is more convenient, reliable, and intelligent. At the same time, with the increase in sensitive loads, vacuum circuit breakers, as an important control and protection device in the primary power system, are required to enable management to understand the operating status of the equipment anytime and anywhere, and to achieve synchronous intelligent operation. These are the requirements for the development of power grid dispatch automation systems towards digitalization, integration, grid-based management, standardization, marketization, and intelligence.

[0003] A search revealed a utility model patent with publication number CN213936041U, which specifically discloses a medium-voltage solid-sealed vacuum circuit breaker with a protective structure. The circuit breaker includes a circuit breaker body, a movable base at the bottom of the body, an operating panel and a connector at the lower and upper front sides of the body, a connector tube and a buffer assembly at the rear side of the body, and vertical guide rails on both sides of the front side of the body, with a dustproof assembly slidably mounted on the guide rails. In use, this utility model uses the buffer assembly to reduce excess impact force on the connector tube during insertion, reducing wear. When not in use, the dustproof assembly covers the connector and operating panel to prevent dust from entering the device and affecting its normal operation.

[0004] Although the aforementioned patent uses a dustproof component to cover the connector and control panel, thereby preventing dust from entering the device and affecting its normal use, the vacuum circuit breaker is exposed to the air during use. Long-term exposure to the air can cause the surface of the vacuum circuit breaker to crack or become brittle due to oxidation, resulting in damage to the vacuum circuit breaker and affecting its normal use.

[0005] Therefore, it is necessary to propose an IoT lighting vacuum circuit breaker with a protective structure to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide an IoT lighting vacuum circuit breaker with a protective structure. Through the cooperation of the internal parts of the protective mechanism, the protective shell can be fixedly installed on the fixed base, and the vacuum circuit breaker body can be sealed and protected. Through the cooperation of the internal parts of the sealing mechanism, the connecting cable between the vacuum circuit breaker body and the protective shell can be sealed and clamped, thereby reducing the penetration of dust or moisture into the vacuum circuit breaker body through the wiring holes on the protective shell, which would affect the vacuum circuit breaker body. This solves the problem in the prior art that when vacuum circuit breakers are exposed to air for a long time, their surface will be affected by oxidation, resulting in cracks or brittleness, which will cause damage to the vacuum circuit breaker and affect its normal use.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an IoT lighting vacuum circuit breaker with a protective structure, comprising a vacuum circuit breaker body, a fixed base connected and fixed to the bottom and back of the vacuum circuit breaker body, and fixed to the wall by bolts, a protective mechanism sleeved on the outer wall of the vacuum circuit breaker body, which is slidably connected to one end of the fixed base and extends into the interior of the fixed base, and multiple sealing mechanisms are provided on the surface of the protective mechanism and are slidably connected to the interior of the protective mechanism;

[0008] The protective mechanism includes a protective shell, which is slidably connected to one side of the fixed base and sleeved with the outer wall of the vacuum circuit breaker body. Multiple metal heat sinks are mechanically connected to the side of the protective shell away from the vacuum circuit breaker body, and the multiple metal heat sinks are in contact with the outer wall of the vacuum circuit breaker body.

[0009] The sealing mechanism includes multiple wiring holes, which are located on the surface of the protective shell away from the main body of the vacuum circuit breaker. A sealing plate is slidably connected to the top and bottom of each wiring hole, extending into the interior of the protective shell. A support spring is fixedly connected to the sealing plate and the protective shell, located on one side of the sealing plate. A clamping plate is slidably connected to the top of the sealing plate, extending into the interior of the sealing plate. A telescopic spring is fixedly connected to the bottom of the clamping plate and the sealing plate. A moving block is slidably connected to the inner wall of the protective shell, located on one side of the bottom of the sealing plate.

[0010] Preferably, the protective mechanism further includes a connecting column, which is slidably connected to the top of the fixed base and extends into the interior of the fixed base. A support column is machined at the bottom of the connecting column, and a fixing block is machined on the side of the support column away from the connecting column, extending into the interior of the protective shell through the fixed base. A return spring is fixedly connected between the bottom of the support column and the fixed base.

[0011] Preferably, the surface of the fixed base is provided with a sliding groove that matches the protective shell, and the inner wall of the protective shell is provided with a protective cavity that matches the body of the vacuum circuit breaker. The metal heat sink is distributed in a fan shape on the outer wall surface of the body of the vacuum circuit breaker.

[0012] Preferably, the wiring hole is connected to the cable sleeve on the vacuum circuit breaker body, an arc groove is provided between the multiple clamping plates, and the inner wall of the sealing plate is provided with a telescopic groove that matches the clamping plate.

[0013] Preferably, the protective shell has a support groove inside that matches the sealing plate, the sealing plate has a chamfer on the side near the moving block, the contact surface between the moving block and the sealing plate has a tapered surface, and the protective shell has a moving groove inside that matches the moving block.

[0014] Preferably, the inner wall of the protective shell is provided with a fixing groove that matches the fixing block, the interior of the fixing base is provided with a spring groove that matches the reset spring, and flexible sealing rings are provided at both ends of the outer wall of the protective shell where they fit with the fixing base.

[0015] The technical effects and advantages provided by this utility model in the above technical solution are as follows:

[0016] 1. By pressing the connecting column, the connecting column is forced to compress the return spring of the support column, causing the support column to compress the return spring and move, which in turn moves the fixed block. The fixed block moves and retracts back into the fixed base. Then the protective shell moves and moves closer to the fixed base. Then the pressure on the connecting column is released, causing the return spring to reset and push the support column to move. The support column moves and moves the fixed block to penetrate into the protective shell, thus completing the connection between the protective shell and the fixed base. The protective shell and the fixed base are sealed together by a flexible sealing ring, thus completing the sealing protection of the vacuum circuit breaker body. At the same time, the metal heat sink is distributed in a fan shape on the outer wall surface of the vacuum circuit breaker body, which facilitates the heat generated by the vacuum circuit breaker body during use to be transferred to the outside of the protective shell through the metal heat sink, thereby completing the heat dissipation operation of the vacuum circuit breaker body.

[0017] 2. The cable passes through the wiring hole to the outer wall of the protective shell. At the same time, the telescopic spring pushes the clamping plates closer together, causing the clamping plates to move out from inside the sealing plate and clamp and fix the cable to the outer wall. After the protective shell and the fixed base are installed and fixed, the protective shell, along with the moving block, comes into contact with the fixed base, causing the fixed base to squeeze the moving block. The moving block is forced to squeeze the sealing plate, and the sealing plate is forced to compress the support spring, causing the sealing plate to move out of the protective shell. This seals and protects the gap of the wiring hole, and at the same time, it provides sleeve protection for the outer wall of the clamping plate. This seals and protects the cable around the wiring hole, reducing the penetration of dust or moisture into the vacuum circuit breaker body through the gap and affecting the normal use of the vacuum circuit breaker body.

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings.

[0028] This utility model provides, for example Figure 1-6The present invention relates to an IoT lighting vacuum circuit breaker with a protective structure, comprising a vacuum circuit breaker body 1, a fixed base 101 connected and fixed to the bottom and back of the vacuum circuit breaker body 1 and fixed to the wall by bolts, a protective mechanism 2 sleeved on the outer wall of the vacuum circuit breaker body 1 and slidably connected to one end of the fixed base 101 and extending into the interior of the fixed base 101, and multiple sealing mechanisms 3 provided on the surface of the protective mechanism 2 and slidably connected to the interior of the protective mechanism 2.

[0029] The protective mechanism 2 includes a protective shell 201, which is slidably connected to one side of the fixed base 101 and sleeved with the outer wall of the vacuum circuit breaker body 1. Multiple metal heat sinks 202 are mechanically connected to the side of the protective shell 201 away from the vacuum circuit breaker body 1, and the multiple metal heat sinks 202 are in contact with the outer wall of the vacuum circuit breaker body 1.

[0030] The sealing mechanism 3 includes multiple wiring holes 301, which are located on the surface of the protective shell 201 away from the vacuum circuit breaker body 1. The top and bottom ends of the wiring holes 301 are slidably connected to sealing plates 302, which penetrate into the interior of the protective shell 201. A support spring 303 is fixedly connected between the sealing plate 302 and the protective shell 201 and is located on one side of the sealing plate 302. A clamping plate 304 is slidably connected to the top end of the sealing plate 302 and penetrates into the interior of the sealing plate 302. A telescopic spring 305 is fixedly connected between the bottom end of the clamping plate 304 and the sealing plate 302. A moving block 306 is slidably connected to the inner wall of the protective shell 201 and is located on one side of the bottom end of the sealing plate 302.

[0031] By cooperating with each other among the internal parts of the protective mechanism 2, the protective shell 201 can be fixedly installed on the fixed base 101, and the vacuum circuit breaker body 1 can be sealed and protected. By cooperating with each other among the internal parts of the sealing mechanism 3, the connecting cable between the vacuum circuit breaker body 1 and the protective shell 201 can be sealed and clamped, thereby reducing the penetration of dust or moisture into the vacuum circuit breaker body 1 through the wiring hole 301 on the protective shell 201, which would affect the vacuum circuit breaker body 1.

[0032] Refer to the instruction manual appendix Figure 1-6 The protective mechanism 2 also includes a connecting column 203, which is slidably connected to the top of the fixed base 101 and extends into the interior of the fixed base 101. A support column 204 is machined at the bottom of the connecting column 203. A fixing block 205 is machined on the side of the support column 204 away from the connecting column 203 and extends into the interior of the protective shell 201 through the fixed base 101. A return spring 206 is fixedly connected between the bottom of the support column 204 and the fixed base 101. Through the mutual cooperation between the internal parts of the protective mechanism 2, the installation and fixation of the protective shell 201 on the fixed base 101 can be completed.

[0033] Refer to the instruction manual appendix Figure 1-6 The surface of the fixed base 101 is provided with a sliding groove that matches the protective shell 201, and the inner wall of the protective shell 201 is provided with a protective cavity that matches the vacuum circuit breaker body 1. The metal heat sink 202 is distributed in a fan shape on the outer wall surface of the vacuum circuit breaker body 1. The fan-shaped distribution of the metal heat sink 202 on the outer wall surface of the vacuum circuit breaker body 1 facilitates the heat generated by the vacuum circuit breaker body 1 during use to be transferred to the outside of the protective shell 201 through the metal heat sink 202, thereby completing the heat dissipation operation of the vacuum circuit breaker body 1.

[0034] Refer to the instruction manual appendix Figure 1-6 The wiring hole 301 is connected to the cable on the vacuum circuit breaker body 1. An arc groove is provided between multiple clamping plates 304. The inner wall of the sealing plate 302 is provided with a telescopic groove that matches the clamping plate 304. The wiring hole 301 is connected to the cable on the vacuum circuit breaker body 1. The arc groove is provided between multiple clamping plates 304 to facilitate the clamping plate 304 to clamp and fix the cable in the wiring hole 301.

[0035] Refer to the instruction manual appendix Figure 1-6 The protective shell 201 has a support groove inside that matches the sealing plate 302. The sealing plate 302 has a chamfer on the side near the moving block 306. The contact surface between the moving block 306 and the sealing plate 302 has a tapered surface. The protective shell 201 has a moving groove inside that matches the moving block 306. By having a chamfer on the side of the sealing plate 302 near the moving block 306 and a tapered surface on the contact surface between the moving block 306 and the sealing plate 302, the moving block 306 can be forced to contact the sealing plate 302.

[0036] Refer to the instruction manual appendix Figure 1-6 The inner wall of the protective shell 201 is provided with a fixing groove that matches the fixing block 205. The interior of the fixing base 101 is provided with a spring groove that matches the reset spring 206. Flexible sealing rings are provided at the joints between the outer walls of the protective shell 201 and the fixing base 101. The flexible sealing rings at the joints between the outer walls of the protective shell 201 and the fixing base 101 facilitate the improvement of the sealing performance between the protective shell 201 and the fixing base 101.

[0037] The working principle of this practical application is as follows:

[0038] Refer to the instruction manual appendix Figure 1-6By pressing the connecting post 203, the connecting post 203 is forced to push the support post 204 to compress the return spring 206. This causes the support post 204 to compress the return spring 206, retracting and moving the fixing block 205. The fixing block 205 retracts back into the fixed base 101, and then the protective shell 201 moves closer to the fixed base 101. The pressure on the connecting post 203 is then released, causing the return spring 206 to reset and push the support post 204 to move. The movement of the support post 204 then moves the fixing block 205. By penetrating into the protective shell 201, the connection between the protective shell 201 and the fixed base 101 can be completed. The protective shell 201 and the fixed base 101 are sealed together by a flexible sealing ring, thus completing the sealing protection of the vacuum circuit breaker body 1. At the same time, the metal heat sink 202 is distributed in a fan shape on the outer wall surface of the vacuum circuit breaker body 1, which facilitates the heat generated by the vacuum circuit breaker body 1 during use to be transferred to the outside of the protective shell 201 through the metal heat sink 202, thereby completing the heat dissipation operation of the vacuum circuit breaker body 1.

[0039] Refer to the instruction manual appendix Figure 1-6 The cable passes through the wiring hole 301 to the outer wall of the protective shell 201. At the same time, the telescopic spring 305 pushes the clamping plate 304 closer together, so that the clamping plate 304 moves out from the sealing plate 302 to clamp and fix the outer wall of the cable. After the protective shell 201 and the fixed base 101 are installed and fixed, the protective shell 201 with the moving block 306 comes into contact with the fixed base 101, so that the fixed base 101 squeezes the moving block 306. The moving block 306 is forced to squeeze the sealing plate 302. The sealing plate 302 is forced to squeeze the support spring 303 to retract and move, so that the sealing plate 302 moves out from the protective shell 201, sealing and protecting the gap of the wiring hole 301. At the same time, it provides sleeve protection for the outer wall of the clamping plate 304. This can seal and protect the cable around the wiring hole 301, thereby reducing the penetration of dust or moisture into the vacuum circuit breaker body 1 through the gap and affecting the normal use of the vacuum circuit breaker body 1.

[0040] The foregoing description only illustrates certain exemplary embodiments of the present invention. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
