Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. 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.

[0021] The utility model provides two technical solutions:

[0022] Figure 1-4The first embodiment is shown: a fully automatic concrete anti-seepage testing device, including a workbench 1, the bottom of the workbench 1 is fixedly connected to a support leg 2, the top of the workbench 1 is fixedly connected to a support frame 7, a telescopic rod 8 is arranged on the top of the support frame 7, the telescopic rod 8 is an electric telescopic rod, and is connected to the control system and the power supply through a wire, the telescopic rod 8 passes through the support frame 7 and extends to the inside of the support frame 7, one end of the telescopic rod 8 located inside the support frame 7 is provided with a connecting cover 4 through a trigger mechanism 3, the connecting cover 4 includes a sealing cylinder 41, the bottom end of the sealing cylinder 41 is fixedly connected to a sealing ring 42, the inner wall of the sealing cylinder 41 is fixedly connected to a second elastic member 43, the other end of the second elastic member 43 is fixedly connected to a support ring 44, and the bottom end of the support ring 44 is fixedly connected to a conductive rod 4 5. The surface of the workbench 1 is provided with a connecting seat 9 adapted to the connecting cover 4. The connecting cover 4 and the connecting seat 9 have the same structure and are symmetrically arranged. A water supply mechanism 5 is provided on one side of the connecting cover 4 and the connecting seat 9. The water supply mechanism 5 includes a water inlet pipe 51. A booster pump 52 is provided at the inlet of the water inlet pipe 51. The booster pump 52 is connected to the control system and the power supply through a wire. The outlet of the water inlet pipe 51 is connected to the connecting seat 9 and the connecting cover 4 through a water distribution hose 53. A detection circuit 6 is provided between the connecting cover 4 and the connecting seat 9. The detection circuit 6 includes a test power supply 61. The negative pole of the test power supply 61 is electrically connected to the support ring 44 of the connecting seat 9 through a wire. The positive pole of the test power supply 61 is connected to a buzzer 62 through a wire. The buzzer 62 is electrically connected to the support ring 44 of the connecting cover 4 through a wire.

[0023] By cooperating with the connection cover 4 and the connection seat 9, the concrete sample is clamped. When the water supply mechanism 5 applies water pressure to the concrete, the pressurized water can only penetrate through the front and back sides of the concrete sample, avoiding water from penetrating along the side walls of the concrete sample, thereby improving the accuracy of the concrete impermeability test results.

[0024] Figure 2 and 3 A second embodiment is shown, which mainly differs from the first embodiment in that the trigger mechanism 3 includes a connecting tube 31, which is fixedly connected to the top of the connecting cover 4, a first elastic member 32 is fixedly connected to the bottom of the inner wall of the connecting tube 31, a movable plate 33 is fixedly connected to the top of the first elastic member 32, the movable plate 33 is slidably connected to the inner wall of the connecting tube 31, the bottom end of the telescopic rod 8 passes through the connecting tube 31 and is slidably connected to the connecting tube 31, one end of the telescopic rod 8 located inside the connecting tube 31 is fixedly connected to the movable plate 33, a control switch 34 is provided at the bottom of the inner wall of the connecting tube 31, and the control switch 34 is connected to the telescopic rod 8 by wires.

[0025] Through the setting of the trigger mechanism 3, during the clamping process, the telescopic rod 8 compresses the first elastic member 32 through the movable plate 33. When the force applied by the sealing ring 42 to the concrete sample reaches a certain value, the movable plate 33 triggers the control switch 34 to shut down the telescopic rod 8, thereby preventing the concrete sample from being subjected to excessive force and affecting the detection result.

[0026] When in use, place the concrete sample to be tested on the connecting seat 9, open the telescopic rod 8 through the control panel, and the telescopic rod 8 works by pushing the connecting cover 4 downward through the trigger mechanism 3 to fit the sealing ring 42 on the concrete sample surface to clamp the concrete sample. During the clamping process, the telescopic rod 8 compresses the first elastic member 32 through the movable plate 33. When the force applied by the sealing ring 42 to the concrete sample reaches a certain value, the movable plate 33 triggers the control switch 34 to shut down the telescopic rod 8 to prevent the concrete sample from being subjected to excessive force and affecting the test result. When the sealing ring 42 fits with the concrete sample, the conductive rod 45 fits with the surface of the concrete sample under the action of the second elastic member 43, and the booster pump 52 is turned on to send the test water to the connecting cover 4 and the connecting seat 9 through the water inlet pipe 51 and the water distribution hose 53, and water pressure is applied to the concrete sample. The buzzer 62 alarms, indicating that the concrete sample is penetrated, and the test personnel record the pressure and time data.
