Description

Technical Field

[0001] This utility model relates to the field of disconnector technology, specifically to a disconnector with a waterproof structure. Background Technology

[0002] A waterproof disconnector is an important piece of electrical equipment, primarily used for the isolation and grounding protection of high-voltage equipment in power systems. It is designed to ensure safety during maintenance and repair while providing effective electrical isolation.

[0003] According to a public announcement (Publication No.: CN 204102786 U), a novel waterproof disconnecting switch includes a high-voltage disconnecting switch operating mechanism box, an operating linkage, and a double-grounded disconnecting switch body. The high-voltage disconnecting switch operating mechanism box is provided with three output shafts, which consist of a main blade output shaft, a left grounding blade output shaft, and a right grounding blade output shaft. The main blade output shaft is connected to the first connecting shaft of the high-voltage disconnecting switch body through a first operating linkage, and the first connecting shaft is connected to the main blade.

[0004] When a waterproof disconnector is used outdoors, it may encounter severe weather conditions such as rain and snow. The ingress of moisture and ice can reduce the insulation performance of the disconnector, potentially causing short circuits or leakage faults. Therefore, protection is required in severe weather. However, the cooperation between components such as the main blade output shaft and the right ground blade output shaft is insufficient to effectively block the direct impact of rain and snow, prevent moisture and ice from entering the disconnector, and reduce the risk of short circuits or equipment failures caused by moisture. This situation needs improvement. Utility Model Content

[0005] This utility model proposes a waterproof disconnect switch, which solves the problems mentioned in the above documents.

[0006] The technical solution of this utility model is as follows: A waterproof disconnect switch includes a bracket, an insulating column is fixedly connected to the top of the bracket, and an outdoor protective device is provided on the side of the bracket. The outdoor protective device includes a crossbar, one end of which is fixedly connected to the side of the bracket. A rotating shaft is rotatably connected to the side of the crossbar, and a gear passes through the circumference of the rotating shaft. A support plate is fixedly connected to the side of the crossbar, and a long rod is fixedly connected to the end of the support plate away from the crossbar. A rack is slidably connected to the top of the long rod, and an electric telescopic rod is fixedly connected to one end of the long rod. The end of the electric telescopic rod away from the long rod is fixedly connected to the side of the rack. An arc rod is fixedly connected to the end of the rotating shaft away from the crossbar, and a protective cover is fixedly connected to one end of the arc rod.

[0007] Furthermore, the rack and gear mesh with each other, and a reinforcing rod is fixedly connected to the side of the arc rod. The end of the reinforcing rod away from the arc rod is fixedly connected to the side of the protective cover. The design of the reinforcing rod can better connect the protective cover and increase the support for the protective cover when it is in use, preventing it from shaking and becoming unstable.

[0008] Furthermore, a switch is provided on the side of the electric telescopic pole, the crossbar is made of metal, the protective cover is located above the insulating column, and the switch design allows for one-button start of the electric telescopic pole, making it convenient to use.

[0009] Furthermore, several insulating columns are provided and arranged in a linear array on the top of the bracket. A fixing plate is fixedly connected to the side of the bracket, and the top of the fixing plate is provided with mounting holes. The design of the mounting holes facilitates the installation and fixing of this double-grounded high-voltage isolation device.

[0010] Furthermore, there are two crossbars, shafts, gears, and long rods, which are symmetrical to each other along the vertical central axis of the protective cover. A conductive switch is provided on the side of the insulating column, which facilitates power control.

[0011] Furthermore, a reinforcement device is provided on the side of the bracket. The reinforcement device includes a diagonal rod, one end of which is fixedly connected to another diagonal rod. A double-ended lead screw passes through the end of the diagonal rod away from the bracket. A connecting band is fixedly sleeved on the circumferential surface of the rotating shaft. The end of the connecting band away from the rotating shaft is fixedly sleeved on the circumferential surface of the double-ended lead screw. A threaded sleeve is threadedly connected to the circumferential surface of the double-ended lead screw. A clamping plate is fixedly connected to the bottom of the threaded sleeve. A limit rod passes through the side of the diagonal rod. The end of the limit rod away from the diagonal rod passes through the side of the threaded sleeve. This reinforcement installation improves the safety of the equipment under harsh outdoor weather conditions.

[0012] Furthermore, there are two threaded sleeves and clamping plates, which are symmetrical to each other along the vertical central axis of the bidirectional screw. The clamping plates are located on the side of the bracket. The clamping force of the two clamping plates is stronger, making the clamping more stable.

[0013] Furthermore, there are two connecting bands, which are symmetrical to each other along the vertical central axis of the bidirectional lead screw. The diagonal brace is made of metal, and there are two fixing plates. The metal diagonal brace has stronger support and can better support the bidirectional lead screw.

[0014] Furthermore, several mounting holes are provided, arranged in pairs and symmetrically along the vertical central axis of the bracket. Several conductive switches are provided, located on the side of the bracket. The more mounting holes provided, the more screws can be installed, making the device more stable.

[0015] Furthermore, two reinforcing rods are provided, and they are symmetrical to each other along the vertical central axis of the protective cover. The reinforcing rods are rectangular strips. The design of two reinforcing rods can make the protective cover more stable to install.

[0016] The working principle and beneficial effects of this utility model are as follows:

[0017] This invention utilizes the interplay of components such as crossbars, electric telescopic rods, gears, racks, and protective covers within the outdoor protective equipment. The protective cover rotates in reverse, enclosing components like insulating posts and conductive switches, thus reducing the impact of rain and snow in severe weather. The protective cover effectively blocks direct impacts from rain and snow, preventing moisture and ice from entering the disconnector switch and reducing the risk of short circuits or equipment malfunctions due to humidity. Prolonged exposure to severe weather, especially humid environments, can lead to corrosion of metal components and aging of insulation materials. Covering the equipment with a protective cover slows down this corrosion and aging process, extending the equipment's lifespan, improving safety, reducing the probability of accidents, and ensuring the safety of operators and equipment.

[0018] This invention utilizes the interplay between components such as the bidirectional lead screw, connecting belt, threaded sleeve, limiting rod, and clamping plate inside the reinforced equipment. This allows the components to be covered by a protective cover during severe rain and snow, while simultaneously securing the device in place. The relative movement of the two clamping plates effectively holds the device in a specific position, preventing accidental movement under strong winds or vibrations. This is crucial for the safety of high-voltage disconnect switches, preventing positional changes due to external forces during operation. In rain and snow, the protective cover effectively prevents moisture and snow from corroding the equipment. Furthermore, the device's fixing mechanism further enhances its wind resistance, ensuring normal operation under extreme weather conditions. Attached Figure Description

[0026] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model. Example

[0027] like Figures 1-5 This embodiment proposes a waterproof disconnect switch, including a bracket 1. An insulating column 2 is fixedly connected to the top of the bracket 1. An outdoor protective device 3 is provided on the side of the bracket 1. The outdoor protective device 3 includes a crossbar 31. One end of the crossbar 31 is fixedly connected to the side of the bracket 1. A rotating shaft 32 is rotatably connected to the side of the crossbar 31. A gear 33 passes through the circumference of the rotating shaft 32. A support plate 35 is fixedly connected to the side of the crossbar 31. A long rod 36 is fixedly connected to the end of the support plate 35 away from the crossbar 31. A rack 38 is slidably connected to the top of the long rod 36. An electric telescopic rod 37 is fixedly connected to one end of the long rod 36. The end of the electric telescopic rod 37 away from the long rod 36 is fixedly connected to the side of the rack 38. An arc rod 39 is fixedly connected to the end of the rotating shaft 32 away from the crossbar 31. A protective cover 311 is fixedly connected to one end of the arc rod 39.

[0028] The rack 38 and the gear 33 mesh with each other. A reinforcing rod 310 is fixedly connected to the side of the arc rod 39. The end of the reinforcing rod 310 away from the arc rod 39 is fixedly connected to the side of the protective cover 311. The design of the reinforcing rod 310 can better connect the protective cover 311 and increase the support for the protective cover 311 when it is in use, preventing it from shaking and becoming unstable.

[0029] The electric telescopic pole 37 has a switch on its side, the crossbar 31 is made of metal, and the protective cover 311 is located above the insulating post 2. The switch is designed to start the electric telescopic pole 37 with one button, making it convenient to use.

[0030] Several insulating columns 2 are arranged in a linear array on the top of the bracket 1. A fixing plate 6 is fixedly connected to the side of the bracket 1. The top of the fixing plate 6 is provided with mounting holes 7. The design of the mounting holes 7 facilitates the installation and fixing of this double-grounded high-voltage isolation device.

[0031] There are two crossbars 31, shafts 32, gears 33, and long rods 36, which are symmetrical to each other along the vertical central axis of the protective cover 311. A conductive switch 5 is provided on the side of the insulating column 2, which facilitates the control of the power supply.

[0032] In this embodiment, when the device is used outdoors, rain and snow may affect its operation. In such cases, the switch on the electric telescopic rod 37 can be pressed to activate it. When the telescopic end of the electric telescopic rod 37 extends towards the insulating post 2, it drives the rack 38 to move towards the insulating post 2 on the long rod 36. The rack 38 and the gear 33 mesh with each other. The movement of the rack 38 will drive the gear 33 to rotate forward, and the protective cover 311 will rotate away from the top of the insulating post 2, the conductive switch 5, and other components, no longer continuously covering them for protection. When the telescopic end of the electric telescopic rod 37 retracts away from the insulating post 2, it will drive the rack 38 to move away from the insulating post 2, thereby driving the gear 33 to rotate in reverse. The rotation of the gear 33 will drive the circular... When the arc rod 39 and the reinforcing rod 310 reverse, the protective cover 311 will also reverse. The reversed protective cover 311 will rotate towards the top of components such as the insulating column 2 and the conductive switch 5, covering these components and reducing the impact of rain and snow in severe weather. The protective cover 311 can effectively block the direct impact of rain and snow, prevent moisture and ice from entering the disconnect switch, and reduce the risk of short circuits or equipment failures caused by moisture. Long-term exposure to severe weather, especially humid environments, will lead to corrosion of metal parts and aging of insulation materials. Covering the equipment with the protective cover 311 can slow down this corrosion and aging process, thereby extending the service life of the equipment, improving the safety of the equipment, reducing the probability of accidents, and ensuring the safety of operators and equipment. Example

[0033] like Figures 1-5Based on the same concept as Embodiment 1 above, this embodiment also proposes another embodiment. A reinforcement device 4 is provided on the side of the bracket 1. The reinforcement device 4 includes a diagonal rod 41. One end of the diagonal rod 41 is fixedly connected to the diagonal rod 41. The end of the diagonal rod 41 away from the bracket 1 is penetrated by a bidirectional lead screw 42. A connecting band 43 is fixedly sleeved on the circumferential surface of the rotating shaft 32. The end of the connecting band 43 away from the rotating shaft 32 is fixedly sleeved on the circumferential surface of the bidirectional lead screw 42. A threaded sleeve 44 is threadedly connected to the circumferential surface of the bidirectional lead screw 42. A clamping plate 46 is fixedly connected to the bottom of the threaded sleeve 44. A limiting rod 45 penetrates the side of the diagonal rod 41. The end of the limiting rod 45 away from the diagonal rod 41 penetrates the side of the threaded sleeve 44. The reinforcement installation is carried out in harsh outdoor weather conditions, which improves the safety of the equipment.

[0034] There are two threaded sleeves 44 and clamping plates 46, which are symmetrical to each other along the vertical central axis of the bidirectional screw 42. The clamping plates 46 are located on the side of the bracket 1. The clamping force of the two clamping plates 46 is stronger, making the clamping more stable.

[0035] There are two connecting straps 43, which are symmetrical to each other along the vertical central axis of the bidirectional lead screw 42. The diagonal bar 41 is made of metal. There are two fixing plates 6. The metal diagonal bar 41 has stronger support and can better support the bidirectional lead screw 42.

[0036] The mounting holes 7 are provided in several pairs and are symmetrical to each other along the vertical central axis of the bracket 1. Several conductive switches 5 are provided and are located on the side of the bracket 1. The more mounting holes 7 are provided, the more screws can be installed, making the device more stable.

[0037] There are two reinforcing rods 310, which are symmetrical to each other along the vertical central axis of the protective cover 311. The reinforcing rods 310 are rectangular strips. The design of two reinforcing rods 310 can make the protective cover 311 more stable to be installed.

[0038] In this embodiment, the rotation of the aforementioned gear 33 drives the connecting belt 43 to rotate. When the gear 33 reverses direction, it drives the connecting belt 43 to reverse direction, which in turn drives the bidirectional lead screw 42 to reverse direction. The reversal of the bidirectional lead screw 42 causes the two threaded sleeves 44 to move relative to each other on the bidirectional lead screw 42. This relative movement of the two threaded sleeves 44 on the bidirectional lead screw 42 simultaneously drives the two clamping plates 46 to move relative to each other. The relative movement of the two clamping plates 46 allows for clamping at a specific point, improving the stability of the device installation, preventing shaking, and achieving [the desired effect]. In severe rain and snow weather, the protective cover 311 not only covers the components on the device but also further secures the device in place. The relative movement of the two clamps 46 can effectively hold the device in a specific position, preventing accidental movement in strong winds or vibrations. This is crucial for the safety of the high-voltage disconnect switch, preventing the equipment from changing position due to external forces during operation. In rain and snow weather, the protective cover 311 can effectively prevent moisture and snow from corroding the equipment. At the same time, the device's fixing mechanism further enhances the equipment's wind resistance, ensuring normal operation under extreme weather conditions.

[0039] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
