[0028] In the embodiment, the support shell 1 provides stable support for the test mechanism 2 and the warning mechanism 3 and the like inside the support shell 1, ensures that the components remain in a stable relative position during the test, the water storage tank 21 serves as a water source storage component and can store sufficient water to meet the demand for multiple penetration simulation of the concrete test piece during the test, the support box 22 provides a suitable space for placing the concrete test piece, the water leakage hole 23 is arranged at the bottom of the inner side of the support box 22, so that the water seeping out of the concrete test piece during the test can be smoothly discharged, avoiding the accumulation of seepage water in the support box 22 and affecting the accuracy of the test results, the connecting plate 24 serves to connect the support shell 1, the spray head 25 and the shunt pipe 26, ensuring the structural stability of the entire water spraying system, the spray head 25 can uniformly spray the water delivered from the shunt pipe 26 on the concrete test piece in the support box 22, the shunt pipe 26 can uniformly distribute the water pumped out by the circulating pump 27 to each spray head 25, ensuring that the water sprayed by each spray head 25 is relatively consistent, the circulating pump 27 can pump the water in the water storage tank 21 and deliver it to the spray head 25 for spraying, and at the same time, the water seeping out of the support box 22 and collected in the water storage tank 21 can participate in the circulation again, and the water pump 28 can smoothly deliver the water in the water storage tank 21 to the circulating pump 27.

[0029] Specifically, as shown in Figure 3 , the warning mechanism 3 includes a flow guide plate 31, a water collecting shell 32, a humidity sensor 33, a micro sensor 34 and a Bluetooth warning lamp 35, and the flow guide plate 31 is arranged in a U-shaped form.

[0032] In the embodiment: by setting the deflector 31 as a U-shaped and fixedly connecting it to the inner side of the water collecting shell 32 in an inverted manner, the water seeping out from the support box 22 and flowing down through the water leakage hole 23 can be smoothly guided into the water collecting shell 32, and the inverted connection provides a relatively closed and stable humidity monitoring environment for the humidity sensor 33.

[0035] In the embodiment: by setting the support rods 4, the stability of the support box 22 in the horizontal direction is ensured, preventing it from shifting or shaking during the process of placing the concrete test piece, bearing the water pressure, etc. By setting the handle 5, it is convenient for researchers to operate the support box 22. When installing or removing the concrete test piece, the support box 22 can be easily pulled out or pushed into the support shell 1 by holding the handle 5. By setting the anti-slip patterns, the friction between the user's hand and the handle 5 is enhanced, ensuring that the operation process is more stable and safe.

[0036] Specifically, as shown in Figure 4 the bottom of the front side of the water storage tank 21 is fixedly connected with a drain pipe 6, the top of the drain pipe 6 is fixedly connected with an on-off valve 7, the top of the front side of the water storage tank 21 is fixedly connected with a water inlet pipe 8, and the top of the water inlet pipe 8 is fixedly connected with a twist cap 9.

[0038] In the present embodiment: by setting the drain pipe 6, the water inside the water storage tank 21 can be discharged after the test is completed or when the water inside the water storage tank 21 needs to be replaced; by setting the on-off valve 7, the opening or closing state of the drain pipe 6 can be set by opening or closing the on-off valve 7; by setting the water inlet pipe 8, the required amount of water can be added to the water storage tank 21 through the water inlet pipe 8, ensuring that the water storage tank 21 can store enough water before each test, meeting the needs of the test process for the penetration simulation of the concrete test piece; by setting the twist cap 9, it can be tightly capped on the top of the water inlet pipe 8, forming a good sealing effect, which can effectively prevent dust, impurities, water vapor and other external factors from entering the water storage tank 21, ensuring the cleanliness of the water in the water storage tank 21; by setting the protective shell 10, the micro sensor 34 can be effectively protected from possible collisions and dust from the outside world, prolonging the service life of the micro sensor 34; by setting the anti-corrosion coating, a protective barrier can be formed on the surface of the protective shell 10, effectively isolating the direct contact between the corrosive substances in the external environment and the protective shell 10, preventing it from being eroded.

[0039] Working principle: First, the user will install the support shell 1 in a suitable working position, then the user holds the handle 5 and pulls it out, so that the support box 22 can slide out along the inside of the support shell 1, then the sulphoaluminate cement concrete test piece that has been shaped and is to be tested for impermeability is placed inside the support box 22, after the placement operation is completed, the user pushes the handle 5 again to make the support box 22 slide smoothly into the inside of the support shell 1 along the support rod 4, so that it returns to the initial test preparation state, then the user unscrews the cap 9, connects the pipeline of the external water source to the water inlet pipe 8, so as to smoothly introduce water into the water storage tank 21, when it is confirmed that the water in the water storage tank 21 has reached the sufficient amount required for testing, the user disconnects the external water source from the water inlet pipe 8, and tightens the cap 9 to close the water inlet pipe 8, at this time, the user turns on the power and starts the circulating pump 27, the circulating pump 27 will start to draw water from the inside of the water storage tank 21 through the water suction pipe 28, the water suction pipe 28 will transport the drawn water into the circulating pump 27, then the circulating pump 27 will pressurize the drawn water and guide it to the shunt pipe 26, the shunt pipe 26 will further evenly distribute the water to each connecting plate 24, and the nozzle 25 connected to the bottom of the connecting plate 24 will spray the pressurized water on the surface of the sulphoaluminate cement concrete test piece, so as to simulate the water flow penetration in the actual environment, if the sulphoaluminate cement concrete test piece is penetrated by water during the water spraying test, the penetrated water will flow down through the water leakage hole 23 at the bottom of the support box 22, fall on the top of the flow guide plate 31, then the water will slowly flow into the funnel-shaped water collecting shell 32 along the two sides of the flow guide plate 31, the water collecting shell 32 can effectively collect the incoming water and guide it back to the inside of the water storage tank 21, realizing the recycling of water, if excessive leakage occurs during the test, the humidity sensor 33 installed on the inside top of the flow guide plate 31 can detect that the water vapor content in the water collecting shell 32 is too high, once the abnormality is detected, the humidity sensor 33 will immediately send a corresponding signal to the microcontroller, after receiving the signal, the microcontroller will quickly start the Bluetooth warning light 35, which will immediately issue a prominent warning information to inform the user that the sulphoaluminate cement concrete test piece has leaked, so that the user can respond quickly, at this time, the user can close the circulating pump 27 according to the warning information, then pull out the support box 22 from the inside of the support shell 1 by pulling the handle 5, and then further detect and analyze the sulphoaluminate cement concrete test piece that has leaked, finally, under the condition that the sulphoaluminate cement concrete test piece does not leak, when the spraying operation of sufficient water amount according to the predetermined test scheme is completed, the user can close the circulating pump 27, then slide the support box 22 out by pushing the handle 5, and finally take out the sulphoaluminate cement concrete test piece from the support box 22, completing the impermeability test process.

[0040] The above merely describes the preferred embodiments of the present application, and is not intended to limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application shall be included in the protection scope of the present application.
