Description

Technical Field

[0001] The present application relates to the technical field of electrical switches, and in particular to an undersea tunnel traffic electrical switch with a waterproof protective shell. Background Art

[0002] An electrical switch is a device for interrupting the flow of electrons in a circuit. Common electrical switches include load switches, circuit breakers, isolating switches, etc. The waterproof performance of electrical switches in submarine tunnel projects is extremely important when used. After searching, a Chinese patent announcement with the authorization announcement number CN218160055U discloses an electrical engineering waterproof electrical switch, including a housing and a power supply. The housing is provided with an electrical switch body. The inner bottom wall of the housing is fixedly connected with two water immersion detectors. The right side of the housing is fixedly connected with a first threading tube, the right end of the first threading tube is fixedly connected with a second threading tube, and the top of the second threading tube is fixedly connected with an alarm. The back of the housing is hinged with a sealing cover plate by a hinge. The housing can be sealed by the cooperation of the sealing cover plate and the sealing gasket to increase the protection of the electrical switch body. The cooperation of the first threading tube and the second threading tube can comb the wires of the device to avoid the wires being messy. The water inside the housing can be monitored in real time by the water immersion detector. The alarm can be used to generate an alarm when the housing is immersed in water, so as to promptly notify the staff to perform maintenance.

[0003] The above scheme uses a sealing gasket to seal and waterproof the connection between the sealing cover and the shell, but in actual operation, it is found that there are still at least the following defects: each time the sealing cover is opened to operate the electrical switch body, the sealing cover is installed back on the shell after the operation is completed. During this process, moisture in the external environment will enter the shell. Especially in the case of high humidity in the external environment in the undersea tunnel, more and more moisture will enter the shell. Over time, the moisture retained in the shell can easily cause the electrical switch body to become damp, short-circuit, damage, etc., thereby reducing the safety performance of the electrical switch body when in use.
