[0004] However, the above technical solution still has some shortcomings. Among them, it is necessary to hold the turntable by hand to adjust the circuit breaker body to move up. This process requires manual operation, which is cumbersome. In addition, when it rains, it is difficult for humans to react in time and quickly adjust the circuit breaker body to move up.

[0005] To this end, the present invention provides a high-voltage gas circuit breaker. Summary of the invention

[0006] The present invention provides a high-voltage gas circuit breaker, which solves the technical problems in the related art that it is cumbersome to manually adjust the upward movement of the circuit breaker body, and it is difficult for humans to react in time and adjust the upward movement of the circuit breaker body when it rains.

[0007] The present invention provides a high-voltage gas circuit breaker, comprising: a base plate, and also comprising: a frame arranged above the base plate, the front and rear ends of the frame being connected; a circuit breaker body installed inside the frame; and a lifting mechanism arranged on the top surface of the base plate, the lifting mechanism being able to automatically lift the frame and the circuit breaker body on rainy days; wherein the lifting mechanism comprises: fixed plates arranged on both sides of the frame, the upper ends of the fixed plates being provided with first through holes; a containing box arranged on a side of the fixed plate away from the frame; and a connecting rope penetrating the first through holes and slidably connected to the fixed plate, the two ends of the connecting rope being respectively fixed to the frame and the containing box.

[0008] Specifically, on rainy days, the sponge in the containing box will become heavier and heavier, and the containing box will drive the frame and the circuit breaker body to move upward through the connecting rope, which can prevent the frame and the circuit breaker body from contacting with a damp or water-logged ground, and can automatically perform waterproofing and moisture-proofing to prevent the circuit breaker body from getting damp. The lifting mechanism can automatically lift the frame and the circuit breaker body, which can prevent the frame and the circuit breaker body from contacting with a damp or water-logged ground, and can automatically perform waterproofing and moisture-proofing to prevent the circuit breaker body from getting damp. There is no need to manually adjust the circuit breaker body to move upward, and the circuit breaker body can be automatically driven to move upward by the weight of rainwater, which is timely, simple and convenient.

[0009] Preferably, it also includes a wind shield for protecting and shielding the circuit breaker body, the wind shield is fixedly connected to the front and rear ends of the fixing plate, when the lifting mechanism lifts the frame and the circuit breaker body, the wind shield can cooperate with the frame to shield and protect the circuit breaker body; and a ventilation mechanism arranged on the bottom plate, the ventilation mechanism can ventilate the circuit breaker body that has been shielded and protected on rainy days.

[0010] Specifically, the wind shield can cooperate with the frame to shield and protect the circuit breaker body. When it rains, it can prevent the air with high humidity in the wind from blowing onto the circuit breaker body. By setting up a ventilation mechanism, the circuit breaker body can be continuously ventilated. The circuit breaker body needs to be kept ventilated. This is mainly because the circuit breaker body will release harmful gases and tiny particles during operation. If the particles are not ventilated and discharged, these particles will adhere to the components of the circuit breaker body, affecting the service life of the circuit breaker body. At the same time, ventilation also helps to disperse the heat generated during the operation of the equipment, ensuring the normal operation of the equipment and extending its life.

[0011] Preferably, the ventilation mechanism includes: an air duct passing through the fixed plate, the air outlet end of the air duct being connected to the inside of the frame and blowing toward the circuit breaker body; and a blowing assembly installed at the air inlet end of the air duct, the blowing assembly being used to blow air into the air duct, and an air outlet hole being opened at the bottom of the frame.

[0012] Preferably, the lifting mechanism further includes a sponge body arranged inside the containing box, and a water flow hole is opened on the bottom surface of the containing box.

[0013] Preferably, the blowing assembly includes: a fan rotatably connected to the air inlet end of the air duct, the fan can blow air into the air duct when rotating, the air duct is located on a side of the fixed plate away from the frame and is made of a hard material, and the air duct is located on a side of the fixed plate close to the frame and is made of a soft material; a first annular gear fixed to the outside of the fan; a bracket rod fixed to the bottom plate; a fixed ring fixed to the top surface of the bracket rod; a rotating ring rotatably mounted on the fixed ring, the rotating ring is located below the water flow hole; a plurality of fan blades circumferentially arranged inside the rotating ring, the fan blades are fixed to the rotating ring; and a second annular gear fixed to the rotating ring.

[0014] Specifically, when it rains continuously, the sponge in the containing box will become heavier and heavier, and the containing box will drive the frame and the circuit breaker body to move upward through the connecting rope, which can prevent the frame and the circuit breaker body from contacting the wet or water-logged ground, and can automatically perform waterproofing and moisture-proofing to prevent the circuit breaker body from getting damp. As it continues to rain, rainwater in the containing box flows out from the water flow holes and impacts the multiple fan blades, and the fan blades can rotate. The fan blades drive the fan to rotate through the rotating ring, the second annular gear, and the first annular gear. When the fan rotates, it can blow air into the air duct, which can keep the circuit breaker body ventilated, which is conducive to the discharge of particulate matter, and prevents particulate matter from adhering to the circuit breaker body, thereby avoiding affecting the service life of the circuit breaker body. At the same time, ventilation also helps to disperse the heat generated during the operation of the equipment, ensure the normal operation of the equipment and extend its life.

[0015] Preferably, it also includes a drying mechanism arranged on the bottom plate, the drying mechanism is used to dry the wind from the ventilation mechanism to the circuit breaker body, the drying mechanism includes: a drying box fixedly connected to the top surface of the fixed plate, a granular desiccant is placed in the drying box, and activated carbon desiccant, bentonite desiccant, quartz desiccant, etc. can be used; a collecting box fixedly connected to the top surface of the bottom plate; a vertical pipe connecting the drying box and the collecting box, the vertical pipe intersects and connects with the air duct; a switch component for controlling the flow or closing of the vertical pipe; and two filters arranged in the air duct, the two filters are arranged on both sides of the vertical pipe.

[0016] Preferably, the switch assembly includes: a switch plate that passes through and is slidably connected to the vertical pipe, the switch plate is arranged obliquely, and a second through hole is opened on the switch plate; and a pull-down rope for connecting the lower end of the switch plate and the receiving box, when the receiving box moves downward, the switch plate can be driven to slide downward through the pull-down rope, and at the same time, the granular desiccant in the drying box can flow downward through the second through hole; a reset member arranged on the upper end of the switch plate for driving the switch plate to move.

[0017] Preferably, the reset member comprises: a fixing platform fixedly connected to the upper end of the switch plate; and a reset spring arranged between the fixing platform and the vertical pipe.

[0018] Preferably, a sliding groove is provided on the top surface of the containing box, and the switch assembly further comprises a moving block slidably disposed in the sliding groove, and the moving block is fixedly connected to the lower end of the pull rope.

[0019] Preferably, the second through hole is in a triangular shape, and the greater the distance the switch plate moves downward, the faster the granular desiccant flows through the second through hole.

[0020] Specifically, since the humidity in the air is high when it rains, the humid air may cause the circuit breaker body to be damp, the insulation performance to decline, and even cause problems such as circuit short circuit. By setting a drying mechanism, when it rains more heavily, the sponge in the receiving box will absorb more water, the receiving box will move downward at a longer speed and distance, the impact force of rainwater flowing out of the water flow hole and impacting the multiple fan blades will also be greater, the fan will rotate faster, and the wind speed of the air duct blowing air to the circuit breaker body will be faster, which means that more air volume needs to be dried in the air duct. When it rains more heavily, the receiving box will drive the switch plate to move downward for a longer distance through the pull-down rope, and can drive the switch plate to move downward for a greater distance. When the switch plate moves downward for a greater distance, the faster the speed of the granular desiccant flowing through the second through hole, the faster the flow rate and the more flow of the granular desiccant can automatically meet the needs of drying more air volume in the air duct. When more air volume is blown into the circuit breaker body in the air duct, it is ensured that the drying mechanism can meet the needs of drying more air volume.

[0021] The beneficial effects of the present invention are as follows: the high-voltage gas circuit breaker described in the present invention, specifically, on rainy days, the sponge body in the containing box will become heavier and heavier, and the containing box will drive the frame and the circuit breaker body to move upward through the connecting rope, which can prevent the frame and the circuit breaker body from contacting with a damp or water-logged ground, and can automatically perform waterproofing and moisture-proofing to prevent the circuit breaker body from getting damp; the lifting mechanism can automatically lift the frame and the circuit breaker body, which can prevent the lifting frame and the circuit breaker body from contacting with a damp or water-logged ground, and can automatically perform waterproofing and moisture-proofing to prevent the circuit breaker body from getting damp; there is no need to manually adjust the circuit breaker body to move upward, and the circuit breaker body can be automatically driven to move upward by the weight of rainwater, and the response is timely, simple and convenient.

[0022] In a high-voltage gas circuit breaker described in the present invention, the wind shield can cooperate with the frame to shield and protect the circuit breaker body. When it rains, it can prevent the air with high humidity in the wind from blowing on the circuit breaker body. By setting a ventilation mechanism, the circuit breaker body can be continuously ventilated. The circuit breaker body needs to be kept ventilated. This is mainly because the circuit breaker body will release harmful gases and tiny particles during operation. If the particles are not ventilated and discharged, these particles will adhere to the components of the circuit breaker body, affecting the service life of the circuit breaker body. At the same time, ventilation also helps to disperse the heat generated during the operation of the equipment, ensuring the normal operation of the equipment and extending its service life.

[0023] A high-voltage gas circuit breaker described in the present invention, when it rains continuously, the sponge in the containing box will become heavier and heavier, and the containing box will drive the frame and the circuit breaker body to move upward through the connecting rope, which can prevent the frame and the circuit breaker body from contacting with the wet or water-logged ground, and can automatically perform waterproof and moisture-proofing to prevent the circuit breaker body from getting wet. As it continues to rain, rainwater in the containing box flows out from the water flow holes and impacts on multiple fan blades, and the fan blades can rotate. The fan blades drive the fan to rotate through the rotating ring, the second annular gear, and the first annular gear. When the fan rotates, it can blow air into the air duct, which can keep the circuit breaker body ventilated, which is conducive to discharging particulate matter, avoiding the particulate matter from adhering to the circuit breaker body, and avoiding affecting the service life of the circuit breaker body. At the same time, ventilation also helps to disperse the heat generated during the operation of the equipment, ensuring the normal operation of the equipment and extending its service life.

[0024] In the high-voltage gas circuit breaker described in the present invention, when it rains more heavily, the containing box will drive the switch plate to move downward a longer distance through the pull-down rope, and can drive the switch plate to move downward a greater distance. When the switch plate moves downward a greater distance, the faster the speed of the granular desiccant flowing through the second through hole, the faster the flow rate and the more flow rate of the granular desiccant can automatically meet the needs of drying more air volume in the air duct. When more air volume is blown into the circuit breaker body in the air duct, it is ensured that the drying mechanism can meet the needs of drying more air volume. BRIEF DESCRIPTION OF THE DRAWINGS

[0035] Specifically, on rainy days, the sponge 45 in the accommodating box 43 will become heavier, and the accommodating box 43 will drive the frame 2 and the circuit breaker body 3 to move upward through the connecting rope 44, which can prevent the frame 2 and the circuit breaker body 3 from contacting with a damp or water-logged ground, and can automatically perform waterproofing and moisture-proofing to prevent the circuit breaker body 3 from getting wet. The lifting mechanism 4 can automatically lift the frame 2 and the circuit breaker body 3, which can prevent the frame 2 and the circuit breaker body 3 from contacting with a damp or water-logged ground, and can automatically perform waterproofing and moisture-proofing to prevent the circuit breaker body 3 from getting wet. There is no need to manually adjust the circuit breaker body 3 to move upward, and the circuit breaker body 3 can be automatically driven to move upward by the weight of rainwater, which is timely, simple and convenient.

[0036] Please refer to Figure 1 , Figure 2 , and also includes a windshield 5 for protecting and shielding the circuit breaker body 3, the windshield 5 is fixedly connected to the front and rear ends of the fixing plate 41, when the lifting mechanism 4 lifts the frame 2 and the circuit breaker body 3, the windshield 5 can cooperate with the frame 2 to shield and protect the circuit breaker body 3; and a ventilation mechanism 6 arranged on the bottom plate 1, the ventilation mechanism 6 can ventilate the circuit breaker body 3 that has been shielded and protected on rainy days.

[0037] Specifically, the wind shield 5 can cooperate with the frame 2 to shield and protect the circuit breaker body 3. When it rains, it can prevent the air with high humidity in the wind from blowing on the circuit breaker body 3. By setting the ventilation mechanism 6, the circuit breaker body 3 can be continuously ventilated. The circuit breaker body 3 needs to be kept ventilated. This is mainly because the circuit breaker body 3 will release harmful gases and tiny particles during operation. If the particles are not ventilated and discharged, these particles will adhere to the components of the circuit breaker body 3, affecting the service life of the circuit breaker body 3. At the same time, ventilation also helps to disperse the heat generated during the operation of the equipment, ensuring the normal operation of the equipment and extending its life.

[0038] Please refer to Figure 2 The ventilation mechanism 6 includes: an air duct 61 that passes through the fixed plate 41, the air outlet end of the air duct 61 is connected to the inside of the frame 2 and blows toward the circuit breaker body 3; and a blowing component 62 installed at the air inlet end of the air duct 61, the blowing component 62 is used to blow air into the air duct 61, and an air outlet hole 63 is opened at the bottom of the frame 2.

[0039] Please refer to Figure 1 , Figure 2 The lifting mechanism 4 also includes a sponge body 45 arranged inside the receiving box 43, and a water flow hole 46 is opened on the bottom surface of the receiving box 43.

[0040] Please refer to Figure 2 , Figure 3The blowing assembly 62 includes: a fan 621 rotatably connected to the air inlet end of the air duct 61, and the fan 621 can blow air into the air duct 61 when rotating, and the air duct 61 is located on the side of the fixed plate 41 away from the frame 2 and is made of hard material, and the air duct 61 is located on the side of the fixed plate 41 close to the frame 2 and is made of soft material; a first annular gear 622 fixedly connected to the outside of the fan 621; a bracket rod 623 fixedly connected to the bottom plate 1; a fixed ring 624 fixedly connected to the top surface of the bracket rod 623; a rotating ring 625 rotatably mounted on the fixed ring 624, and the rotating ring 625 is located below the water flow hole 46; a plurality of fan blades 626 circumferentially arranged inside the rotating ring 625, and the fan blades 626 are fixedly connected to the rotating ring 625; and a second annular gear 627 fixedly connected to the rotating ring 625.

[0041] Specifically, when it rains continuously, the sponge 45 in the containing box 43 will become heavier, and the containing box 43 will drive the frame 2 and the circuit breaker body 3 to move upward through the connecting rope 44, so as to prevent the frame 2 and the circuit breaker body 3 from contacting with the wet or water-logged ground, and can automatically perform waterproof and moisture-proofing to prevent the circuit breaker body 3 from getting wet. As it rains continuously, the rainwater in the containing box 43 flows out from the water flow hole 46 and impacts the plurality of fan blades 626, and the fan blades 626 can rotate. The fan blades 626 drive the fan 621 to rotate through the rotating ring 625, the second annular gear 627, and the first annular gear 622. When the fan 621 rotates, it can blow air into the air duct 61, so as to keep the circuit breaker body 3 ventilated, which is conducive to discharging particulate matter, and preventing particulate matter from adhering to the circuit breaker body 3, so as to avoid affecting the service life of the circuit breaker body 3. At the same time, ventilation also helps to disperse the heat generated during the operation of the equipment, ensure the normal operation of the equipment and extend its service life.

[0042] Please refer to Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 6 , and also includes a drying mechanism 7 arranged on the bottom plate 1, the drying mechanism 7 is used to dry the wind from the ventilation mechanism 6 to the circuit breaker body 3, and the drying mechanism 7 includes: a drying box 71 fixedly connected to the top surface of the fixing plate 41, wherein a granular desiccant is placed in the drying box 71, and an activated carbon desiccant, a bentonite desiccant, a quartz desiccant, etc. can be used; a collecting box 72 fixedly connected to the top surface of the bottom plate 1; a vertical pipe 73 for connecting the drying box 71 and the collecting box 72, wherein the vertical pipe 73 intersects and connects with the air duct 61; a switch assembly 74 for controlling the flow or closing of the vertical pipe 73; and two filter screens 75 arranged in the air duct 61, wherein the two filter screens 75 are arranged on both sides of the vertical pipe 73.

[0043] Please refer to Figure 5 , Figure 6The switch assembly 74 includes: a switch plate 741 that penetrates and is slidably connected to the vertical pipe 73, the switch plate 741 is tilted, and a second through hole 742 is opened on the switch plate 741; and a pull-down rope 743 used to connect the lower end of the switch plate 741 and the receiving box 43. When the receiving box 43 moves downward, the switch plate 741 can be driven to slide downward through the pull-down rope 743. At the same time, the granular desiccant in the drying box 71 can flow downward through the second through hole 742; a reset member 744 is arranged on the upper end of the switch plate 741 for driving the switch plate 741 to move.

[0044] Please refer to Figure 5 The reset member 744 includes: a fixing platform 7441 fixedly connected to the upper end of the switch plate 741 ; and a reset spring 7442 arranged between the fixing platform 7441 and the vertical pipe 73 .

[0045] Please refer to Figure 4 , Figure 5 A sliding groove 745 is provided on the top surface of the accommodating box 43 , and the switch assembly 74 further includes a moving block 746 slidably arranged in the sliding groove 745 , and the moving block 746 is fixedly connected to the lower end of the pull-down rope 743 .

[0046] Please refer to Figure 6 The second through hole 742 is in a triangular shape. When the switch plate 741 moves downward a greater distance, the granular desiccant flows through the second through hole 742 faster.

[0047] Specifically, when it rains, the humidity in the air is high, and the humid air may cause the circuit breaker body 3 to be damp, the insulation performance to decline, and even cause problems such as a short circuit. By setting the drying mechanism 7, when it rains more heavily, the sponge 45 in the receiving box 43 will absorb more water, and the receiving box 43 will move downward at a longer speed and distance. The impact force of rainwater flowing out of the water flow hole 46 and impacting the plurality of fan blades 626 will also be greater, the speed of the fan 621 rotating will be faster, and the wind speed of the wind duct 61 blowing air to the circuit breaker body 3 will be faster. At this time, it means that the air duct 61 needs to be ventilated. The more air volume for drying treatment, the heavier the rain, the longer the distance the switch plate 741 can move downward through the pull-down rope 743, and the greater the distance the switch plate 741 moves downward, the faster the speed of the granular desiccant flowing through the second through hole 742. The faster the flow rate and the more flow rate of the granular desiccant, the more air volume can be automatically dried in the air duct 61. When more air volume is blown into the circuit breaker body 3 in the air duct 61, it is ensured that the drying mechanism 7 can dry more air volume.
