Description

Technical Field

[0001] This utility model relates to the field of disconnector switch technology, and in particular to a waterproof disconnector switch device. Background Technology

[0002] Disconnect switches are the most widely used electrical appliances in high-voltage switchgear. Their working principle and structure are relatively simple, but due to their large usage and high reliability requirements, they have a significant impact on the design, construction, and safe operation of substations and power plants. The function of disconnect switches in circuits is to isolate power sources to ensure the safety of circuit and equipment maintenance.

[0003] When disconnect switches are installed outdoors, they need to be waterproofed. Most existing waterproofing methods involve placing the disconnect switch inside a cabinet and closing the cabinet after closing to achieve waterproofing. However, when maintenance or repair is required in rainy weather, the cabinet needs to be opened. During the opening process, external rainwater can easily splash into the cabinet, which can easily lead to electric shock hazards and endanger the safety of maintenance personnel. Utility Model Content

[0004] To address the problems of existing technologies, this utility model provides a waterproof device for disconnecting switches. The basic concept of the technical solution adopted by this utility model to solve the aforementioned technical problems is as follows:

[0005] A waterproof device for a disconnecting switch includes a waterproof housing. A bracket is fixed to the bottom surface of the waterproof housing. Ceramic resistors are fixed to the top of the bracket near both ends. A cover plate is provided between the tops of the waterproof housing. An adjustment knob is rotatably mounted on the top of the cover plate. A sealing gasket is fixed to the bottom of the cover plate. The bottom of the adjustment knob extends through to below the sealing gasket. An insulating lever is fixed to the bottom of the adjustment knob. One side of the insulating lever is inclined.

[0006] Optionally, one of the ceramic resistors is fixed to the top of a copper pillar, and a side slot is provided on one side of the copper pillar.

[0007] Optionally, a copper sleeve is fixed to the top of another ceramic resistor, a torque ring is fixed to the outer surface of the copper sleeve, and a knife plate is fixed to the outer surface of the torque ring.

[0008] Optionally, one outer surface of the switch plate extends into the interior of the side slot, and the other outer surface of the switch plate is in contact with one outer surface of the insulating switch plate.

[0009] Optionally, the top of the cover plate has a fan-shaped constraint groove on one side of the adjustment knob, and a constraint lever is fixed to the outer surface of the adjustment knob. The bottom of the constraint lever is slidably fitted with the inner bottom surface of the fan-shaped constraint groove.

[0010] Optionally, the four outer surfaces of the sealing gasket are in contact with the four inner walls of the waterproof shell, and the bottom of the sealing gasket extends into the interior of the waterproof shell.

[0011] Optionally, an electrical interface is provided on one side of the waterproof housing.

[0012] By adopting the above technical solution, this utility model has the following beneficial effects compared with the prior art. Of course, any product implementing this utility model does not necessarily need to achieve all of the following advantages at the same time:

[0013] 1. In this utility model, one side of the switch plate extends into the interior of the side bayonet. A torque ring generates torque pressure on the switch plate, so that one side of the switch plate can be pressed tightly into the interior of the side bayonet. The outer surface of the other side of the switch plate is in contact with the outer surface of one side of the insulating lever. When the adjustment knob is rotated, the insulating lever can be driven to move the switch plate away from the side bayonet, thereby separating the switch plate from the side bayonet to achieve the purpose of cutting off the circuit.

[0014] 2. In this utility model, when the adjustment knob is rotated, the mutual constraint between the constraint lever and the sector constraint groove can prevent the adjustment knob from rotating too much. This avoids the problem that when the adjustment knob rotates too much, the insulating plate separates the switch plate from the side latch, and the switch plate resets when the insulating plate flips to the other side. The entire closing and opening process is completed inside the waterproof shell, without the need to open the cover, thus ensuring high safety during closing and opening. Attached Figure Description

[0021] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the present invention in any way, but rather to illustrate the concept of the present invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0022] The present invention will now be described in further detail with reference to the accompanying drawings.

[0023] Example 1, as Figure 1-3 As shown, this utility model provides a technical solution for a waterproof device for isolating switches: it includes a waterproof shell 1, a bracket 9 fixed to the bottom surface of the waterproof shell 1, ceramic resistors 8 fixed to the top of the bracket 9 near both ends, a cover plate 2 between the tops of the waterproof shell 1, an adjustment knob 5 rotatably mounted on the top of the cover plate 2, a sealing gasket 3 fixed to the bottom of the cover plate 2, the bottom of the adjustment knob 5 extending through to below the sealing gasket 3, and an insulating lever 15 fixed to the bottom of the adjustment knob 5, one side of the insulating lever 15 being inclined.

[0024] The effect achieved by the entire embodiment 1 is that one side of the switch plate 13 extends into the interior of the side latch 12, and the torque ring 14 generates torque pressing force on the switch plate 13, so that one side of the switch plate 13 can be pressed tightly into the interior of the side latch 12, while the outer surface of the other side of the switch plate 13 is in contact with the outer surface of one side of the insulating lever 15. When the adjustment knob 5 is rotated, the insulating lever 15 can be driven to push the switch plate 13 away from the side latch 12, thereby separating the switch plate 13 from the side latch 12, so as to achieve the purpose of cutting off the circuit.

[0025] Example 2, as Figure 1-3 As shown, a copper pillar 11 is fixed to the top of one of the ceramic resistors 8, and a side bayonet 12 is provided on one side of the copper pillar 11. A copper sleeve 10 is fixed to the top of the other ceramic resistor 8, and a torque ring 14 is fixed to the outer surface of the copper sleeve 10. A switch plate 13 is fixed to the outer surface of the torque ring 14. One side of the outer surface of the switch plate 13 extends into the interior of the side bayonet 12. The other side of the outer surface of the switch plate 13 is in contact with one side of the outer surface of the insulating switch plate 15. A fan-shaped constraint groove 6 is provided on the top of the cover plate 2 on one side of the adjustment knob 5. A constraint swing rod 7 is fixed to the outer surface of the adjustment knob 5. The bottom of the constraint swing rod 7 slides in contact with the inner bottom surface of the fan-shaped constraint groove 6. The four outer surfaces of the sealing gasket 3 are in contact with the four inner walls of the waterproof shell 1, and the bottom of the sealing gasket 3 extends into the interior of the waterproof shell 1. An electrical interface 4 is provided on one side of the waterproof shell 1.

[0026] The overall effect of embodiment 2 is that when the adjustment knob 5 is rotated, the mutual constraint between the constraint lever 7 and the sector constraint groove 6 can prevent the adjustment knob 5 from rotating too much. This avoids the problem that when the adjustment knob 5 rotates too much, the insulating plate 15 separates the switch plate 13 from the side latch 12, and the switch plate 13 resets when the insulating plate 15 is flipped to the other side. The entire closing and opening process is completed inside the waterproof shell 1, without the need to open the cover plate 2, thus ensuring high safety during closing and opening.

[0027] Working principle: One side of the knife plate 13 extends into the side bayonet 12. The torque ring 14 generates torque pressure on the knife plate 13, pressing one side of the knife plate 13 tightly into the side bayonet 12. The outer surface of the other side of the knife plate 13 is in contact with the outer surface of one side of the insulating lever 15. When the adjustment knob 5 is rotated, the insulating lever 15 can be driven to move the knife plate 13 away from the side bayonet 12, thereby separating the knife plate 13 from the side bayonet 12 to cut off the circuit. When the adjustment knob 5 is rotated, the mutual constraint of the constraint lever 7 and the sector constraint groove 6 can prevent the adjustment knob 5 from rotating too much. This avoids the problem of the knife plate 13 resetting after the insulating lever 15 flips to the other side after the knife plate 13 is separated from the side bayonet 12. The entire closing and opening process is completed inside the waterproof shell 1, without opening the cover plate 2, resulting in high safety during closing and opening.
