However, in the power system, the outdoor high-voltage disconnect switch is one of the important electrical equipment. However, the existing outdoor high-voltage disconnect switches are prone to water accumulation in rainy and snowy weather, which causes the equipment to become damp and icy, affecting the normal operation and service life of the equipment.

[0004] Therefore, we provide a drainage-type base for an outdoor high-voltage disconnect switch to solve the above problems. Utility Model Content

[0005] The purpose of this utility model is to provide a drainage-type base for an outdoor high-voltage disconnect switch, thereby solving the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a drainage-type base for an outdoor high-voltage disconnect switch, comprising a high-voltage disconnect switch connecting seat and a high-voltage disconnect switch drainage assembly. The high-voltage disconnect switch drainage assembly includes a drainage slope disposed on the outside of the high-voltage disconnect switch connecting seat. Both ends of the high-voltage disconnect switch connecting seat are equipped with drainage grooves. The lower inner end of each drainage groove is provided with a mounting groove. A heat-conducting steel plate is installed on the inner side of each mounting groove. A support frame is installed on the inner side of the high-voltage disconnect switch connecting seat. A steel plate electric wire heater is installed on the inner side of the support frame. A reinforcing rib is provided on the lower side of the mounting groove.

[0007] Preferably, the drainage slope and the high-voltage disconnect switch connection base are arranged in three symmetrical sets on the left and right sides.

[0008] Preferably, the hydrophobic groove and the high-voltage disconnect switch connector are welded together, and the hydrophobic groove and the high-voltage disconnect switch connector are symmetrically arranged on the left and right sides.

[0009] Preferably, the heat-conducting steel plate and the mounting groove are connected by a slot, the heat-conducting steel plate is tightly fitted to the high-voltage disconnect switch connecting seat and the inner wall of the mounting groove, and the steel plate electric wire heater and the heat-conducting steel plate form a heating structure through the high-voltage disconnect switch connecting seat and the mounting groove.

[0010] Preferably, the reinforcing rib is welded to the mounting groove, and the reinforcing rib is made of steel.

[0011] Preferably, a sealing gasket is adhered to the upper side of each high-voltage disconnector connector, and a disconnector column is provided on the inner side of each sealing gasket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] 1. When needed, the drainage slope, by its own angle, can guide rainwater into the drainage groove, thereby ensuring that the accumulated water is quickly discharged and preventing water from damaging the equipment. The drainage groove can quickly drain the accumulated water, ensuring that the equipment is dry and avoiding electrical faults caused by water accumulation. The reinforcing ribs can effectively enhance the structural strength of the mounting groove, drainage groove and high-voltage disconnect switch connection seat, preventing deformation or damage caused by water pressure or external impact, ensuring the long-term stable operation of the whole device in harsh environments, and improving the service life and reliability of the equipment.

[0014] 2. In rainy or snowy weather, the steel plate electric wire heater is activated remotely, transferring heat to the heat-conducting steel plate. The heat-conducting steel plate then transfers the heat to the high-voltage disconnect switch connector and the drainage groove, effectively preventing ice formation on the surface of the drainage groove and the high-voltage disconnect switch connector, ensuring unobstructed drainage, and further improving the stability and safety of equipment operation. Meanwhile, the sealing gasket, by tightly adhering to the disconnect switch column, effectively isolates external moisture and dust, preventing them from intruding into the internal circuitry, ensuring the dryness and cleanliness of the disconnect switch column, further guaranteeing the stable electrical performance of the equipment in complex environments and extending its service life.

Detailed Implementation

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 As shown, this utility model provides a technical solution: a drainage type base for an outdoor high-voltage disconnect switch, including a high-voltage disconnect switch connecting seat 1 and a high-voltage disconnect switch drainage assembly 2. The high-voltage disconnect switch drainage assembly 2 includes a drainage slope 201 disposed on the outside of the high-voltage disconnect switch connecting seat 1. Both the left and right ends of the high-voltage disconnect switch connecting seat 1 are equipped with drainage grooves 202. The lower inner end of the drainage grooves 202 is provided with a mounting groove 203. The inner side of the mounting groove 203 is equipped with a heat-conducting steel plate 204. The inner side of the high-voltage disconnect switch connecting seat 1 is equipped with a support frame 205. The inner side of the support frame 205 is equipped with a steel plate electric wire heater 206. The lower side of the mounting groove 203 is provided with a reinforcing rib 207.

[0022] Furthermore, the drainage ramp 201 and the high-voltage disconnect switch connection seat 1 are arranged in three symmetrical sets on the left and right sides. When needed, the drainage ramp 201 tilts at its own angle to guide rainwater into the drainage groove 202, thereby ensuring that the accumulated water is discharged quickly and avoiding damage to the equipment.

[0023] Furthermore, the drainage groove 202 is welded to the high-voltage disconnect switch connecting seat 1. The drainage groove 202 and the high-voltage disconnect switch connecting seat 1 are symmetrically arranged on the left and right sides. When needed, the drainage groove 202 can quickly drain the accumulated water to ensure that the equipment is dry and avoid electrical faults caused by water accumulation.

[0024] Furthermore, the heat-conducting steel plate 204 and the mounting groove 203 are connected by a slot. The heat-conducting steel plate 204 is tightly fitted to the inner wall of the high-voltage disconnecting switch connecting seat 1 and the mounting groove 203. The steel plate electric wire heater 206 and the heat-conducting steel plate 204 form a heating structure through the high-voltage disconnecting switch connecting seat 1 and the mounting groove 203. In rainy or snowy weather, the steel plate electric wire heater 206 can be started remotely by manual control to conduct heat to the heat-conducting steel plate 204. The heat-conducting steel plate 204 then transfers heat to the high-voltage disconnecting switch connecting seat 1 and the drainage groove 202, thereby effectively preventing ice from forming on the surface of the drainage groove 202 and the high-voltage disconnecting switch connecting seat 1, ensuring unobstructed drainage, and further improving the stability and safety of equipment operation.

[0025] Furthermore, the reinforcing rib 207 is welded to the mounting groove 203. The reinforcing rib 207 is made of steel. When needed, the reinforcing rib 207 can effectively enhance the structural strength of the mounting groove 203, the drainage groove 202, and the high-voltage disconnect switch connection seat 1, preventing deformation or damage caused by water pressure or external impact, ensuring the long-term stable operation of the entire device in harsh environments, and improving the service life and reliability of the equipment.

[0026] Furthermore, a sealing gasket 3 is bonded to the upper side of the high-voltage disconnector connector 1, and a disconnector column 4 is provided on the inner side of the sealing gasket 3. When in use, the sealing gasket 3 effectively isolates external moisture and dust by tightly adhering to the disconnector column 4, preventing them from intruding into the internal circuit, ensuring the dryness and cleanliness of the disconnector column 4, further ensuring the stable electrical performance of the equipment in complex environments, and extending its service life.

[0027] Working principle: The drainage base of an outdoor high-voltage disconnect switch is moved to the working position. First, the high-voltage disconnect switch connecting seat 1 is fixed to the desired position through the outer bolt holes. Second, in rainy or snowy weather, the steel plate wire heater 206 inside the support frame 205 is manually controlled to heat the heat-conducting steel plate 204 installed in the mounting groove 203. The heat emitted by the heat-conducting steel plate 204 heats the drainage slope 201 and the drainage groove 202, melting the snow, which then drains along the drainage groove 202. During this process, the reinforcing rib 207 improves the overall support. Finally, during long-term use, the disconnect switch column 4 achieves a sealing effect through the sealing gasket 3. This completes the usage process of the drainage base of the outdoor high-voltage disconnect switch.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
