Separating-type three-proofing temperature controller for rail traffic

Abstract

The invention discloses a separating-type three-proofing temperature controller for rail traffic. The temperature controller includes a liquid crystal display screen, a temperature control module, a main control room, a wiring room and a waterproof joint; the front of the main control room is provided with a main panel, and the four corners of the main panel are hermetically fixed on the main control room through installment screws to form a closed structure; the temperature control module is installed inside the main control room, and a liquid crystal display is embedded on the main panel ofthe main control room; the temperature control module is connected with the liquid crystal display screen and one end of the waterproof joint separately, and a sealing diaphragm is arranged between the main control room and the wiring room; the other end of the waterproof joint runs through the sealing diaphragm and is positioned in the wiring room, and the interior of the wiring room is fixedly provided with the wiring switch; the bottom of the wiring room is provided with a wire outlet. According to the separating-type three-proofing temperature controller for rail traffic, the wiring room is separated from the main control room, and the main control room is designed to be closed. The waterproof joint is used to replace a 25-pin socket and taken as the connector of a sensor cable, and the sealing and water resistance performances are ensured.

Description

technical field [0001] The invention relates to the field of transportation equipment, in particular to a separate three-proof temperature controller for rail transportation. Background technique [0002] Rail transit thermostats are commonly used in urban subways. During the early excavation of subways, transformer supporting thermostats entered the site during the civil construction period. At this time, the dust and humidity in the subway are very large, sometimes reaching the state of dripping water. [0003] There are problems in the existing thermostat shell: 1) The shell is not sealed, and the moisture and dust on the transformer site will cause abnormal LCD display. 2) When wiring, the user must open the thermostat shell, and there is a phenomenon that the shell is not closed and locked after wiring. 3) Cables and devices belong to an open environment, and their service life will be reduced. 4) The traditional temperature sensor cable is connected to the main body...

AI Technical Summary

Problems solved by technology

[0003] There are problems with the existing thermostat casing: 1) The casing is not sealed, and moisture and dust on the transformer site will cause abnormal LCD display

2) When the user is wiring, the thermostat shell must be opened, and there is a phenomenon that the shell is not closed and locked after connecting the wires

3) Cables and devices belong to an open environment, and the service life will be reduced

4) The traditional temperature sensor cable is connected to the main body of the thermostat with a 25-core connector, which cannot be sealed and waterproof
