Description

Technical Field

[0001] This utility model relates to the field of products related to rain testing, specifically a rain test chamber water circulation filtration system. Background Technology

[0002] Rain testing is a crucial part of research and development, used to examine the ability of equipment casings to prevent rainwater penetration and their operational performance during and after exposure to rain. A rain testing chamber is a testing device used to test the water resistance of products or materials. It simulates the rain environment a product experiences in nature, evaluating the product's performance under rain conditions by artificially controlling parameters such as rain temperature, intensity, and duration.

[0003] However, some impurities in the current rain test laboratory's return water circulation system can move with the water flow. Under the water pressure of the pump, hard impurities can also easily enter the pipes. Under high water pressure, they will generate a certain impact force that will damage the equipment, which is a defect. Utility Model Content

[0004] The purpose of this invention is to provide a rain test chamber water return circulation filtration system to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a rain test chamber return water circulation filtration system, comprising an installation box and a water pump. One end of the water pump is fixedly connected to the bottom of the installation box via a water pumping pipe, and the other end of the water pump is fixedly connected to a delivery pipe. A filter box is fixedly connected to the top of the installation box. The bottom of the filter box has two symmetrically arranged water outlets. A support rod is fixedly connected to the top of the filter box. A limit sleeve is fixedly fitted onto the support rod. A filter screen is fitted onto the top of the support rod. A positioning cylinder is fixedly inserted into the middle of the filter screen. The positioning cylinder is slidably fitted onto the support rod. A pressure cover is fitted onto the top of the support rod. A connecting pipe is fixedly connected inside the pressure cover. The inner wall of the connecting pipe has an internal thread. The outer wall of the top of the support rod has an external thread. The connecting pipe and the support rod are threaded together.

[0006] Preferably, a gripping block is fixedly connected to the top of the pressure cover.

[0007] Preferably, the bottom outer wall of the pressure cover is provided with multiple anti-slip textures arranged at an angle.

[0008] Preferably, the inner bottom of the mounting box is fixedly connected to two oppositely arranged guide plates.

[0009] Preferably, the filter screen is configured with a rectangular structure.

[0010] Compared with the prior art, the beneficial effects of this utility model are:

[0011] This rain test chamber water circulation filtration system uses pre-set grooves on the floor of the test chamber corresponding to the installation box and the water pump pipe. The installation box is installed at the water outlet of the test chamber. The positioning cylinder on the filter screen is placed on the support rod inside the filter box. Then, the connecting pipe inside the pressure cover is aligned with the support rod and screwed in. When the threads are screwed in, the pressure cover moves to press against the positioning cylinder, thus supporting and fixing the filter screen on the limiting sleeve. The water is filtered through the filter screen. This invention can filter impurities in the water, prevent impurities from clogging the pipes, and make the disassembly and assembly of the filter components more convenient and subsequent cleaning easier.
