Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] Reference Figure 1-3The utility model provides an embodiment: a concrete research and development experimental water injection device, including a workbench 1, a test box 2 is fixedly connected to the top of the workbench 1, a horizontal plate 3 is fixedly connected to the top of the rear side of the test box 2, an electric push rod 4 is fixedly connected to the top of the horizontal plate 3, and the number of electric push rods 4 is four. The output end of the electric push rod 4 penetrates to the bottom of the horizontal plate 3. A water storage tank 5 is arranged at the bottom of the electric push rod 4. A water volume observation plate 20 is installed at the rear side of the water storage tank 5. The user can observe the water volume inside the water storage tank 5 through the water volume observation plate 20. The bottom of the water storage tank 5 is fixedly connected to the top of the workbench 1, and both sides of the front side of the water storage tank 5 are fixedly connected to the connecting plate 21. The front side of the connecting plate 21 is fixedly connected to the rear side of the test box 2. The water storage tank 5 is auxiliary reinforced by the connecting plate 21 to prevent the water storage tank 5 from shaking after long-term use. The output end of the electric push rod 4 is fixedly connected with a circular plate 6, and the surface of the circular plate 6 is fixedly connected with a rubber ring 7, and the surface of the rubber ring 7 contacts the inner wall of the water storage tank 5. The top of the inner cavity of the water storage tank 5 is threadedly connected with a limit ring 22, and the bottom of the limit ring 22 contacts the top of the circular plate 6. The limit of the circular plate 6 by the limit ring 22 can prevent the circular plate 6 from moving too much and escaping from the inside of the water storage tank 5. The front side of the top of the circular plate 6 is connected with a pressure relief valve 8, and the water flow in the overpressure state inside the water storage tank 5 is discharged through the pressure relief valve 8, which can prevent the water storage tank 5 from being damaged by overpressure in the event of a fault, thereby improving the safety of the water storage tank 5. The rear side of the top of the circular plate 6 is connected to a rubber hose 9, and a one-way water inlet valve 10 is installed on the surface of the rubber hose 9. The bottom of the water storage tank 5 is connected to a water injection pipe 11, and the end of the water injection pipe 11 away from the water storage tank 5 passes through the interior of the experimental box 2, and a one-way water outlet valve 12 is installed on the surface of the water injection pipe 11. The bottom of the experimental box 2 is connected to a drain pipe 13, and a water collecting tank 14 is arranged at the bottom of the drain pipe 13. The front and rear sides of the top of the water collecting tank 14 are fixedly connected with a transparent splash plate 23, and the top of the transparent splash plate 23 is fixedly connected to the surface of the workbench 1. The transparent splash plate 23 is used to protect splashed water droplets, so as to prevent water droplets from splashing to the ground. The right side of the water collecting tank 14 is fixedly connected to the surface of the workbench 1, and a suspension frame group 24 is fixedly connected to the surface of the water collecting tank 14. The top of the suspension frame group 24 is fixedly connected to the surface of the workbench 1. The suspension frame group 24 reinforces the water collecting tank 14, which can prevent the water collecting tank 14 from tilting when there is a large amount of water inside.

[0034] Reference Figure 3-5A filter assembly is installed on the surface of the water collecting box 14, and the filter assembly includes a filter plate 15. The filter plate 15 is arranged inside the water collecting box 14, and the filter plate 15 is located at the bottom of the drain pipe 13. The inside of the water collecting box 14 is fixedly connected with a limit plate group 16, and the surface of the limit plate group 16 contacts the surface of the filter plate 15. The bottom of the water collecting box 14 is connected with a drain valve 17. Through the mutual cooperation of the filter plate 15, the limit plate group 16 and the drain valve 17, the water discharged from the inside of the experimental box 2 can be filtered to solve the problem that the concrete particles are discharged with the water flow and cause the pipe to be blocked.

[0035] Reference Figure 1-3 The surface of the horizontal plate 3 is fixedly connected with a reinforcement component, and the reinforcement component includes an inclined plate 18, which is fixedly connected to the bottom of the horizontal plate 3, and the front side of the inclined plate 18 is fixedly connected to the rear side of the experimental box 2. The top of the horizontal plate 3 is fixedly connected with a reinforcement strip 19, and the surface of the reinforcement strip 19 is fixedly connected to the surface of the experimental box 2. The auxiliary reinforcement of the horizontal plate 3 by the inclined plate 18 and the reinforcement strip 19 can prevent the horizontal plate 3 from being deformed after long-term use.

[0036] Working principle: the user first connects the rubber hose 9 to the external water tank, starts the electric push rod 4, and the output end of the electric push rod 4 drives the circular plate 6 and the rubber ring 7 to move upward. When the circular plate 6 and the rubber ring 7 move upward, the one-way water outlet valve 12 closes the water injection pipe 11. At this time, the inside of the water storage tank 5 is in a negative pressure state. The water storage tank 5 in the negative pressure state sucks the water flow inside the external water tank into the water storage tank 5 through the one-way water outlet valve 12 and the rubber hose 9. When the top of the circular plate 6 contacts the bottom of the limit ring 22, the electric push rod 4 can be started in the reverse direction, and the electric push rod 4 can be started in the reverse direction. The output end of the rod 4 drives the circular plate 6 and the rubber ring 7 to move downward, the circular plate 6 and the rubber ring 7 squeeze the water inside the water storage tank 5, the one-way water inlet valve 10 closes the rubber hose 9, and the water is discharged from the water injection pipe 11 and the one-way water outlet valve 12 to conduct a water permeability test on the concrete. The pressure relief valve 8 can perform protective pressure relief when the water storage tank 5 is over-pressured. The water after the test is discharged from the drain pipe 13, and then the particulate matter is filtered through the filter plate 15, and finally enters the water collecting tank 14 for storage. The water collecting tank 14 can be drained by opening the drain valve 17.

[0037] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention.
