The outlet end of the pump body 4 is connected to the outlet pipe, and the other end of the outlet pipe is connected to the upper wall of the water tank 1. The terminal of the outlet pipe is connected to a plurality of soft branch pipes 8, and the number of soft branch pipes 8 is the same as the number of nozzle assemblies. By starting the pump body 4 to output high-pressure fluid, the outlet pipe is equivalent to the main pipe. Under the power of the pump body 4, the experimental water inside the water tank 1 is respectively passed into the nozzle assembly through the inlet pipe 5 and the outlet pipe through each soft branch pipe 8.

[0026] A bypass return pipeline is connected between the water storage tank 1 and the outlet pipeline, and a bypass return pipeline valve 9 is arranged on the bypass return pipeline. The bypass return pipeline is preferably arranged at the lower part of the water storage tank 1 near the bottom position to realize water return.

[0027] The outlet pipeline is provided with an outlet pipeline valve 6 and a flow meter 7. The outlet pipeline valve 6 can be used to control the flow of the fluid in the outlet pipeline, and the flow meter 7 can be used to obtain the outlet pipeline flow.

[0028] The water tank 1 is also provided with a jet fluid collection and detection device 3, which is arranged on the inner wall of the water tank 1 through a connecting piece. The jet fluid collection and detection device 3 is provided with a collection groove, which is arranged corresponding to the nozzle assembly, has the same number as the nozzle assembly, and is arranged directly below the nozzle assembly. The jet flow of each nozzle assembly is collected through the collection groove to measure the size of the jet flow.

[0029] The nozzle assembly specifically includes a nozzle 13, a nozzle valve 17, a spray distance adjustment device 10, a spray angle adjustment device 11 and a pressure gauge 12. The fluid flows into the nozzle 13 through the soft branch pipe 8 and is sprayed out by the nozzle 13. The nozzle valve 17 can control the on-off of the fluid in the corresponding nozzle 13, select the nozzle 13 that needs to work, and adjust the flow in the nozzle 13. The pressure gauge 12 can display the flow of the nozzle 13. By adjusting the nozzle valve 17, the on-off and size of the flow at the nozzle 13 can be adjusted. The spray distance of the nozzle 13 can be adjusted by the spray distance adjustment device 10. The spray angle can be adjusted by the spray angle adjustment device 11. In addition, by adjusting the spacing adjustment device 2, the spacing between each nozzle 13 can be adjusted.

[0030] Thus, the spraying effect of a single nozzle and a spray beam under different nozzle spacings, different distances, and different spraying angles can be simulated to obtain experimental verification under various conditions.

[0032] It should be noted that during the experiment, the operator can freely choose one or more of the above-mentioned adjustment devices, depending on the experimental requirements, which is not limited in this article.

[0033] When the detection device provided by the present application is used to conduct a single nozzle experiment, the spray angle and spray distance of the nozzle 13 can be adjusted by the spray angle adjustment device 11 and the spray distance adjustment device 10. When the multi-nozzle experiment is conducted by simulating a spray beam (multi-nozzle), the spacing between the nozzles 13 can be adjusted by the spacing adjustment device 2 to achieve the desired simulation effect. The spray fluid is collected by the spray fluid collection detection device 3 to determine the spray effect of the nozzle 13.

[0034] In addition, in order to stabilize the pressure of the nozzle 13, a pressure adjustment and stabilization device is further provided in the pipeline, and the pressure adjustment and stabilization device includes a throttling orifice plate 14 and a shock absorbing device 15. The throttling orifice plate 14 is provided on the outlet pipeline, and the shock absorbing device 15 is fixed to the outer wall of the outlet pipeline by a locking member.

[0035] In a specific embodiment, the spacing adjustment device 2 includes a guide slide bar, a slide key and a locking screw. The guide slide bar is arranged on the top of the water storage tank 1. The guide slide bar is provided with a slide groove extending along its length direction. The nozzle assembly is provided with a slide key. The slide key and the slide groove are slidably matched to adjust the spacing between the two nozzle assemblies. After the spacing adjustment is completed, the nozzle assembly and the guide slide bar are fastened with the locking screw to fix the position of the nozzle assembly.

[0036] The above-mentioned chute is preferably but not limited to a T-shaped chute, and the corresponding sliding key adopts a T-shaped sliding key, which has a simple structure and is easy to process. The structures of the chute and the sliding key can also be varied.

[0037] The above-mentioned jet fluid collection and detection device 3 is internally provided with a grid groove, which subdivides the interior of the jet fluid collection and detection device 3 into a plurality of small grids. The water storage tank 1 corresponding to the grid groove is provided with scale markings, which can more intuitively determine the size of the jet flow at different positions and make the measurement more accurate.

[0038] In order to conveniently pour out the liquid in the jet fluid collection and detection device 3, pins can be set on two opposite outer walls of the jet fluid collection and detection device 3, so that the jet fluid collection and detection device 3 is rotatably mounted on the side wall of the water storage tank 1 and fastened with a locking nut. When it is necessary to pour out the liquid, the locking nut is loosened, and the jet fluid collection and detection device 3 is turned over to pour out the water, which is convenient and quick to operate. After pouring, the jet fluid collection and detection device 3 is turned over and reset, and then fastened with a locking nut.

[0039] In summary, the present application mainly has: a fluid transmission structure, a pressure adjustment and stabilization structure, a spray distance and spacing adjustment structure, a spray angle adjustment structure, and a spray flow collection and detection structure. The fluid transmission device can provide a stable high-pressure fluid, and the pressure adjustment and stabilization device can provide the nozzle with the required stable experimental pressure.
