Description

Technical Field

[0001] This utility model relates to the technical field of water spray test equipment, specifically to a device suitable for high-pressure water spray tests with adjustable angle. Background Technology

[0002] In industrial production and scientific research, evaluating the waterproof performance of parts is crucial. For example, automotive components require excellent waterproofing to withstand complex driving environments. However, existing waterproof performance testing equipment has several problems. Taking the waterproof testing equipment for parts disclosed in Chinese Patent Publication No. CN208012814U as an example, it can only provide water flow impact from a single angle, making it difficult to comprehensively simulate the multi-directional water flow encountered by parts in actual use, resulting in poor accuracy of the test results. Furthermore, the water jet range is small, failing to fully cover the part surface in a short time, leading to low testing efficiency. Additionally, the high-speed water jet nozzle is prone to colliding with the part under test, causing damage to the part or nozzle and increasing testing costs. Utility Model Content

[0003] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a device suitable for high-pressure water spray experiments with adjustable angle.

[0004] The technical solution adopted in this utility model is as follows: A device suitable for angle-adjustable high-pressure water spray experiments includes an experimental chamber, and a self-rotating device and a high-pressure water spray device disposed within the experimental chamber, wherein: The self-rotating device includes a rotating base located at the bottom of the experimental chamber and a fixed fixture located on the upper surface of the rotating base. The rotating base drives the fixed fixture to rotate. The fixed fixture is equipped with the part to be tested. A high-pressure water spray device, located on one side of a rotating platform, includes a fixed base at the bottom of the experimental chamber, a support frame on the fixed base, and a water spray adjustment device and a cylinder mounted on the support frame. A guide rail is provided on the fixed base, and the bottom of the support frame moves along the fixed base via the guide rail to adjust the distance between the high-pressure water spray device and the self-rotating device. The cylinder includes a cylinder body at the top of the support frame and a piston end facing downwards. The water spray adjustment device includes a water pipe, a high-pressure nozzle at the end of the water pipe, and limiting plates mounted on both sides of the high-pressure nozzle. The high-pressure nozzle is limited within the support frame by the limiting plates. The high-pressure nozzle is hinged to the end of the piston end via a hinge shaft. Driven by the piston end, the high-pressure nozzle moves up and down along the support frame. The high-pressure nozzle sprays high-pressure water towards the part under test.

[0005] This technical solution introduces a self-rotating device and an adjustable high-pressure water spray device to achieve multi-angle, multi-parameter high-pressure water flow impact experiments on the test parts, thereby more conveniently evaluating the waterproof performance of the test parts. Specifically, the test chamber provides a relatively closed and controllable environment for the entire experimental process, reducing external interference; in the high-pressure water spray device, the guide rail and support frame on the fixed base cooperate to adjust the distance between the water spray device and the self-rotating device; the cylinder, through the cooperation of the cylinder end and the piston end, uses the piston end to drive the high-pressure nozzle to move up and down, combined with the hinge shaft, so that the high-pressure nozzle can flexibly adjust the spray angle to achieve high-pressure water flow spraying at different angles; the high-pressure nozzle pressurizes the water flow and sprays it onto the test parts, and by controlling the pressure and flow rate, the performance of the test parts under complex water flow conditions is examined.

[0006] In addition, the device for angle-adjustable high-pressure water spray experiments proposed above according to this utility model also has the following additional technical features: According to one embodiment of the present invention, a rotary drive motor is provided at the bottom of the rotating base.

[0007] In this technical solution, the rotary drive motor drives the part under test on the rotating base to rotate continuously during the test, so that all angles of the part under test are sprayed with high-speed water.

[0008] According to one embodiment of the present invention, the fixing fixture has a pre-reserved insertion hole and a slot. The part to be tested is placed in the slot and fixed by inserting a pin into the insertion hole.

[0009] In this technical solution, the pin is inserted into the insertion hole, which, in a direction perpendicular to the plane of the slot, restricts the vertical movement of the part under test and its rotation around its own axis, providing stable axial and rotational constraints for the part under test. Different slot fixtures are selected for different parts under test.

[0010] According to one embodiment of the present invention, the high-pressure nozzle is adjustable in an angle range of 0-25° along the hinge axis.

[0011] In this technical solution, the water flow impacts vertically at 0°, generating the maximum normal pressure, suitable for testing the vertical compressive strength of an object. As the angle increases, the water flow force can be decomposed into vertical and horizontal components, simulating water erosion in different directions. The high-pressure nozzle remains stationary during the test, with its tilt angle adjusted only before the test begins.

[0012] According to one embodiment of the present invention, the high-pressure water jet from the high-pressure nozzle falls in a fan shape onto the surface of the part to be tested.

[0013] In this technical solution, the high-pressure water flow unfolds in a fan shape, which makes the high-pressure water flow spread evenly along the fan direction at the outlet, which facilitates the expansion of the contact area between the water flow and the part to be tested. Compared with a single linear water flow, the fan-shaped water flow can cover a larger area in a shorter time.

[0014] According to one embodiment of the present invention, a proximity switch is installed at the high-pressure nozzle.

[0015] In this technical solution, if the high-speed nozzle touches the part under test during the high-pressure water spray test, it will damage the part under test or the high-speed nozzle. The proximity switch monitors the distance between the high-speed nozzle and the part under test in real time. When the distance is less than the preset safety value, an alarm is triggered to prevent collision.

[0016] According to one embodiment of the present invention, the water pipe is connected to a three-dimensional circulating water tank via a water pump.

[0017] Compared with the prior art, this utility model has the following advantages: This invention uses a self-rotating device to ensure that the part under test is sprayed from all angles. The high-pressure nozzle can be adjusted from 0 to 25° and sprays a fan-shaped water flow, which can simulate water flow from different directions, expand the contact area, cover a larger area in a shorter time, comprehensively examine the performance of the part under test under complex water flow conditions, and evaluate the waterproof performance more accurately.

The high-pressure nozzle 83 is limited within the support frame 7 by the limiting plates 82. The high-pressure nozzle 83 is hinged to the end of the piston end 92 via a hinge shaft 84. The high-pressure nozzle 83 moves up and down along the support frame 7 under the drive of the piston end 92. The high-pressure nozzle 83 sprays high-pressure water towards the part 4 to be tested.

[0025] In this technical solution, the rotary drive motor drives the part under test 4 on the rotary base 2 to rotate continuously during the test, so that all angles of the part under test 4 are sprayed with high-speed water.

[0026] According to one embodiment of the present invention, the fixing fixture 3 has a pre-reserved insertion hole and a slot, and the part to be tested 4 is placed in the slot and fixed by inserting a pin into the insertion hole.

Different slot fixing fixtures 3 are selected for different parts under test 4.

[0028] According to one embodiment of the present invention, the high-pressure nozzle 83 is angularly adjusted within a range of 0-25° along the hinge axis 84.

[0029] In this technical solution, the water flow impacts vertically at 0°, generating the maximum normal pressure, which is suitable for testing the vertical compressive strength of an object. As the angle increases, the water flow force can be decomposed into vertical and horizontal components, simulating water flow erosion in different directions.
