Problems solved by technology

[0003] The air circulation system and heat exchange system of the environmental test device are very critical. The service life of the air circulation system and heat exchange system plays a decisive role in the life of the environmental test device. Since the environmental test device needs to simulate the environment under various harsh conditions, especially Salt mist, rain, dust, and light environments have a greater impact on the air circulation system and heat exchange system. After a period of use, the evaporator, heating pipes, and fans of the air circulation system are prone to aging , resulting in a lower service life

Embodiment 1

[0030] refer to figure 1 , in an embodiment of the present invention, a protection mechanism for an environmental test device, including a drive device, a sealing plate, a slide rail 500, and a slider 400, the cover plate is connected to the output end of the drive device, and the slide rail 500 is installed on the environmental test device 100, the slider 400 is slidably sleeved on the slide rail 500, and the sealing plate is fixedly connected with the sliding block 400. When the sealing plate is closed, the sealing plate seals the wind circulation area 102 and / or the heat dissipation area 102 on the environmental test device 100 Exchange area 101.

[0031] When the environmental test device 100 performs salt spray, sandblasting, and spray tests, the driving device drives the sealing plate to move, and the sliding block 400 and the sliding rail 500 work together to make the sealing plate move along the direction of the sliding rail 500, and the sealing plate moves After it i...

Embodiment 2

[0037] refer to figure 2 The difference between this embodiment and Embodiment 1 is that the cylinder 200 includes a first output end 203 and a second output end 204, and the sealing plate includes a first sealing plate 301 and a second sealing plate 302, and the first sealing plate 301 is connected to the first output end 203, and the second sealing plate 302 is connected to the second output end 204. When the first sealing plate 301 is closed, it seals the heat exchange area 101. When the second sealing plate 302 is closed, it seals the Wind circulation area 102 . There are two output ports in one cylinder. When the air is supplied to the cylinder 200, the first output port 203 and the second output port 204 move in two opposite directions, thereby driving the first sealing plate 301 and the second sealing plate respectively. 302 movement, and finally realize the sealing of the air circulation area 102 and the heat exchange area 101.

Abstract

The invention discloses a protection mechanism of an environmental test device and a control method of the protection mechanism. The protection mechanism of the environmental test device comprises a driving device, a sealing plate, slide rails and slide blocks, wherein the sealing plate is connected with an output end of the driving device; the slide rails are mounted on the environmental test device and sleeved with the slide blocks in a slideable manner; the sealing plate is fixedly connected with the slide blocks; and when the sealing plate is enclosed, the sealing plate encloses an air circulation area and / or a heat exchange area on the environmental test device. When the environmental test device is used for test in a harsh environment, the driving device drives the sealing plate to move along the slide rails, so that the air circulation area and / or the heat exchange area on the environmental test device are / is enclosed; the air circulation area is internally provided with a fan; the heat circulation area is internally provided with an evaporator and a heating pipe; the components play a key role in the environmental test device; and during the test in the harsh environment, the key components are enclosed and can be less contacted with the harsh environment, so that the service life is prolonged.

Description

technical field [0001] The invention relates to the technical field of environmental testing devices, in particular to a protection mechanism of the environmental testing device and a control method thereof. Background technique [0002] The environmental test device can simulate multiple environmental conditions in nature, and has comprehensive, practical, and high-simulation functions, and has high requirements for operation and maintenance. [0003] The air circulation system and heat exchange system of the environmental test device are very critical. The service life of the air circulation system and heat exchange system plays a decisive role in the life of the environmental test device. Since the environmental test device needs to simulate the environment under various harsh conditions, especially Salt mist, rain, dust, and light environments have a greater impact on the air circulation system and heat exchange system. After a period of use, the evaporator, heating pipe...
