Raining laboratory

Abstract

The invention discloses a raining laboratory which comprises a water outlet pipe, an adjusting seat is fixedly arranged at the top of the water outlet pipe, a mounting groove is formed in the adjusting seat, a fixing block is fixedly connected to the top of the inner wall of the mounting groove, and a traction rod is movably arranged in the middle of the fixing block; and a water outlet groove is formed in the position, corresponding to the traction rod, of the adjusting seat, a water outlet seat is fixedly connected to the inner wall of the water outlet groove, the traction rod is movably connected to the inner wall of the water outlet seat, a rubber ball is fixedly connected to the end, away from the fixing block, of the traction rod, and a sealing block is movably connected to the surface of the rubber ball. The rubber ball is driven to move through the traction rod, so that the rubber ball can drive the sealing block to move on the inner wall of the water outlet seat, the water outlet amount of the water outlet seat is changed by moving the distance between the sealing block and the water outlet seat and the distance between the rubber ball and the water outlet seat, and therefore the impact force of liquid sprayed from a spraying head is changed; therefore, the purpose of effectively simulating the raining when an automobile runs is achieved.

Description

technical field [0001] The invention relates to the technical field of a rain laboratory, in particular to a rain laboratory. Background technique [0002] The rain test is divided into a swing-pipe spray test and a nozzle spray test. The rain test is suitable for aviation, automobiles, home appliances, external lighting and signaling devices, and the protection of automotive lamp shells. It is well known that military equipment will be affected by various waters to varying degrees whether they are in working or Rain is the most common effect, and some equipment, although protected from rain, can also be affected by condensation or leaking water on exposed upper surfaces. When it rains, due to the penetration, flow, impact and accumulation of rainwater, it will have various effects on military equipment and its materials. For example, heavy rain can interfere with the transmission of radar signals; heavy raindrops can erode the surfaces of high-speed aircraft and missiles;...

Problems solved by technology

[0003] However, when the existing technology is actually used, because the car is stationary in the laboratory, the simulation effect of the simple spray test is poor, and the situation when the car is running cannot be effectively simulated.
