Description

TECHNICAL FIELD

[0001] The utility model relates to concrete detection technical field, concretely is a kind of concrete impermeability test device. BACKGROUND

[0002] In the field of construction engineering, as a kind of widely used building material, the performance of concrete is directly related to the quality and durability of building. Impermeability is one of the important indicators to measure the performance of concrete, which reflects the ability of concrete to resist pressure water penetration. Good impermeability can effectively prevent water, harmful chemicals and other substances from entering the interior of concrete, thereby avoiding problems such as steel corrosion, concrete freeze-thaw damage, and prolonging the service life of building.

[0003] At present, when detecting the impermeability of concrete, the commonly used method is to apply a certain pressure water to the concrete test piece by using impermeability test device, and to evaluate the impermeability performance by observing the penetration of test piece within a certain time. However, the existing concrete impermeability test device has some shortcomings. On the one hand, most of the existing test devices cannot detect the pressure value in real time. During the test process, the operator cannot timely understand the real-time situation of the pressure, and can only roughly judge whether the pressure is stable through regular manual inspection. This leads to that the test result will be greatly affected under the condition of unstable pressure, and the real impermeability performance of concrete cannot be accurately reflected. Therefore, we propose a kind of concrete impermeability test device. SUMMARY

The existing concrete impermeability test device has some shortcomings. On the one hand, most of the existing test devices cannot detect the pressure value in real time. During the test process, the operator cannot timely understand the real-time situation of the pressure, and can only roughly judge whether the pressure is stable through regular manual inspection. This leads to that the test result will be greatly affected under the condition of unstable pressure, and the real impermeability performance of concrete cannot be accurately reflected.

[0005] In order to achieve the above object, the utility model provides the following technical scheme: a kind of concrete permeability test device, including shell, the right front end of the top of shell is fixedly connected with motor, the output end of motor is fixedly connected with screw rod, the surface of screw rod is threadedly connected with connecting sleeve, the inner wall of connecting sleeve is fixedly connected with fixed tube, the bottom of fixed tube is fixedly connected with sealing washer, the middle axis of shell bottom is fixedly connected with water tank, the left side of water tank is communicated with water pump, one side of water pump is communicated with first bellows, the bottom of the left side of fixed tube is communicated with second bellows, the top of the outside of fixed tube is fixedly connected with support, the top of support is fixedly connected with electric telescopic rod, the bottom of electric telescopic rod is fixedly connected with pressure sensor, the bottom of pressure sensor is fixedly connected with sealing disc.

[0009] Preferably, the rear side of the inner cavity of the connecting sleeve is slidingly connected with a sliding rod, and the bottom of the sliding rod is fixedly connected with the shell.

[0010] Preferably, the right side of the top of the water tank is communicated with a water filling pipe, the bottom of the right side of the water tank is communicated with a water outlet pipe, and the front of the water outlet pipe is movably connected with a control valve.

[0011] Preferably, the right side of the shell is fixedly connected with a fixed rod, the right side of the fixed rod is fixedly connected with the connecting plate, and the surface of the fixed rod is slidingly connected with the adjusting plate.

[0012] Preferably, the bottom of the screw rod is movably connected with the shell through a bearing, and a circular hole is formed in the middle axis of the top of the shell.

[0013] Compared with the prior art, the utility model provides a kind of concrete permeability test device, with the following beneficial effects:

[0014] 1. This utility model places the material at the central axis at the bottom of the inner cavity of the housing. Then, the motor is started by the external PLC controller, which drives the lead screw to rotate. The lead screw drives the connecting sleeve to move, the connecting sleeve drives the fixed pipe to move, and the fixed pipe drives the sealing gasket to move, so that the bottom of the sealing gasket is in close contact with the material. Then, the water pump is started to draw water out of the inner cavity of the water tank and discharge the water into the inner cavity of the fixed pipe through the first corrugated pipe. Then, two pressure values ​​are set, and the electric telescopic rod is started. The electric telescopic rod drives the pressure sensor to move, and the pressure sensor drives the sealing plate to move. After the sealing plate moves into the inner cavity of the fixed pipe, the pressure sensor will detect an increase in pressure. When the detected pressure value is the same as the set first pressure value, it will control the electric telescopic rod to stop working. Then, the anti-seepage test is performed. When the detected pressure value drops to the same as the set second pressure value, it will control the external buzzer to work to remind the staff, so that the staff can observe in time. Even if there is no water leakage, the anti-seepage effect can be detected as substandard.

[0015] 2. After testing, the solenoid valve is opened to allow water to flow back into the water tank cavity. Then, the motor is started, causing the connecting sleeve to rise. During the rising process, the connecting sleeve will contact the triangular plate and drive the triangular plate to move. After the connecting sleeve is higher than the triangular plate, the spring push will drive the adjusting plate to move. The adjusting plate will drive the triangular plate to move to the bottom of the connecting sleeve, thus achieving a limiting effect. Then, the material can be replaced, avoiding equipment failure during the material replacement process that could cause the fixed pipe to descend and squeeze the worker's arm.
