Embodiment Construction

[0020] In order to facilitate the understanding of the present invention, the present invention will be described more fully below with reference to the associated drawings. Preferred embodiments of the invention are shown in the drawings. However, the present invention can be embodied in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present invention more thorough and comprehensive.

[0021] It should be noted that when an element is referred to as being “fixed” to another element, it can be directly on the other element or there can also be an intervening element. When an element is referred to as being "connected to" another element, it can be directly connected to the other element or intervening elements may also be present. As used herein, the terms "vertical", "horizontal", "left", "right", "upper", "lower", "front", "rear", "circumferential" and...

Abstract

The invention relates to the technical field of immersion tests, and discloses an immersion test device comprising a test box body, a control system, a water circulation system and a lifting system. The control system outputs a water circulation control instruction and a lifting instruction to the water circulation system and the lifting system. When a test sample in the test box body needs to beimmersed in water, the water circulation system is controlled to inject test water into the test box body, and when the test water in the test box body needs to be discharged, the water circulation system is controlled to discharge water. When the test sample needs to be immersed in water, the lifting system is controlled to drive the test sample placed on the lifting system to ascend and descendso as to complete the corresponding immersion action. The lifting system comprises a water pressure sensor connected with the control system. The water pressure sensor acquires the water pressure of the position of the test sample and transmits the water pressure to the control system, and the control system performs feedback control on the lifting instruction according to the water pressure to prevent influence of water surface rising caused by the volume of the sample on test conditions.

Description

technical field [0001] The invention relates to the technical field of water immersion test, in particular to a water immersion test device. Background technique [0002] After the equipment is immersed in water, it will cause physical impact and chemical corrosion. Equipment that is often used outdoors may be immersed in rain or wading. Therefore, corresponding to outdoor equipment such as automotive lamps, wipers, waterproof strips, motorcycle instruments, etc., it is necessary to perform an immersion test before installation and use. When performing immersion tests on equipment, high and low temperature liquid tank test devices are usually used. With the rapid development of unmanned vehicles and unmanned aerial vehicles, unmanned vehicles, unmanned aerial vehicles and other equipment also urgently need to test their adaptability in extreme climate environments in the laboratory. Water immersion test equipment for electronic equipment such as cars and drones. Contents...
