[0026] Furthermore, the flushing mechanism 1 includes a recovery box 101, and the left and right sides of the recovery box 101 are respectively fixedly connected with a mounting plate 105 and a fixing plate 111, and a water outlet pipe 109 is rotatably connected to the mounting plate 105 and the fixing plate 111, and a first motor 103 is fixedly connected to one side of the mounting plate 105, and a belt transmission structure 104 is provided between the output shaft of the first motor 103 and the left end of the water outlet pipe 109, and a solenoid valve 106 is connected to the surface of the water outlet pipe 109, and a nozzle 108 is connected to the solenoid valve 106, and a filter screen 102 is fixedly connected to the inside of the recovery box 101, and the filter screen 102 is inclined. A hose 107 is connected to the surface of the water outlet pipe 109, and one end of the hose 107 is connected to a water pump 110 fixed on the surface of the recovery box 101, and a filter 112 is connected to the liquid inlet end of the water pump 110, and the liquid inlet end of the filter 112 passes through the bottom of the inner cavity of the recovery box 101.

[0027] Specifically, there are several solenoid valves 106 , which are evenly distributed on the surface of the water outlet pipe 109 .

[0028] By setting up the flushing mechanism 1, it is convenient to use water flows at different angles to flush the concrete blocks, so as to simulate more real scenes for experiments, and to understand the flushing resistance of concrete under various conditions, to obtain more complete experimental data, and to recycle the flushing water flow, thereby reducing the waste of water resources.

[0029] During the operation of the flushing mechanism 1, the water pump 110 draws water from the inner cavity of the recovery box 101 through the filter 112, and the filter 112 filters the fine particles in the water. The filtered water is transported to the outlet pipe 109 through the hose 107, and the water inside the outlet pipe 109 is sprayed out through the solenoid valve 106 and the nozzle 108. The sprayed water flow is flushed on the concrete block to simulate the flushing experiment. The flushed water flows through the filter screen 102 and flows back to the inner cavity of the recovery box 101. The filter screen 102 filters the large particles in the water. The solenoid valve 106 can control the flow rate of the water flow. When the flushing angle needs to be adjusted, the first motor 103 drives the belt transmission structure 104 to work, and the belt transmission structure 104 drives the outlet pipe 109 to rotate. The outlet pipe 109 drives the nozzle 108 to rotate through the solenoid valve 106, thereby adjusting the flushing angle.

[0030] Furthermore, the moving mechanism 2 includes a slide rail 201, the bottom of the slide rail 201 is fixedly connected to the top of the recycling box 101, the inner wall of the slide rail 201 is rotatably connected to a screw rod 204, the surface of the screw rod 204 is threadedly sleeved with a nut sleeve 203, the surface of the nut sleeve 203 is slidably connected to the inner wall of the slide rail 201, the top of the nut sleeve 203 is fixedly connected to the bottom of the mounting frame 301, and a second motor 202 is provided on one side of the slide rail 201, and the output shaft of the second motor 202 is fixedly connected to one end of the screw rod 204.

[0031] By setting up the moving mechanism 2, the concrete block can be driven to move and the position of the concrete block can be changed. After the position of the concrete block is changed, the pressure of water flow scouring will also be different. When the concrete block is close to the water flow outlet, the scouring pressure is greater. When the concrete block is far away from the water flow outlet, the pressure will also be reduced, thereby simulating different scouring scenes.

[0032] During the operation of the moving mechanism 2, the output shaft of the second motor 202 drives the screw rod 204 to rotate, the screw rod 204 drives the nut sleeve 203 to slide inside the slide rail 201, and the nut sleeve 203 drives the mounting frame 301 to slide on the top of the recycling box 101, thereby changing the position of the concrete block.

[0033] Furthermore, the mounting mechanism 3 includes a mounting frame 301, and a slide groove 304 is provided on both the front and rear sides of the mounting frame 301.

The top and bottom of the slider 302 both extend to the outside of the slide groove 304 and are threadedly sleeved with a fastening nut 303.

[0034] By setting up the mounting mechanism 3, it is convenient to fix concrete blocks of different sizes to meet different experimental requirements. After the concrete block is placed inside the mounting frame 301, the position of the orifice plate 305 can be changed by moving the slider 302 inside the slide groove 304. The orifice plate 305 drives the threaded rod 306 to move to the front and back sides of the concrete block. After the movement is completed, the threaded rod 306 is rotated, and the threaded rod 306 drives the clamping head 307 to move to clamp and fix the concrete block. After the fixation is completed, the fastening nut 303 is sleeved on the upper and lower sides of the slider 302, and the fastening nut 303 is pressed against the surface of the mounting frame 301 to limit the slider 302.
