[0019] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figures 1 - 3 , the present invention discloses a leak detection device for building waterproof materials, including a bottom box 1. The upper surface of the bottom box 1 is an open structure. Observation windows 2 are embedded on the front and rear side walls of the bottom box 1. A partition board 3 is fixedly installed on the inner wall of the bottom box 1 near the upper side wall edge. A grid board 4 is fixedly embedded in the middle position of the partition board 3. Lifting mechanisms 5 are fixedly installed on the upper surface of the partition board 3 near the left and right positions, and a cylinder 6 is fixedly installed between the left and right lifting mechanisms 5. The lower surface of the cylinder 6 is an open structure. A pressing plate 7 is fixedly installed on the lower side edge position of the inner wall of the cylinder 6. A waterproof sealing ring can be embedded on the lower surface of the pressing plate 7 to make the sealing effect between the pressing plate 7 and the upper surface of the waterproof material better. A rubber pad 8 is fixedly installed on the upper surface of the pressing plate 7. A driving mechanism 9 is fixedly installed on the upper side wall of the cylinder 6. A sealing plate 10 is fixedly installed on the lower surface of the driving mechanism 9. The lower surface of the sealing plate 10 is in close contact with the upper surface of the rubber pad 8. Sector holes 11 are formed in a rectangular shape at corresponding positions on the pressing plate 7, the rubber pad 8, and the sealing plate 10. The pressing plate 7, the rubber pad 8, and the sealing plate 10 are all circular structures, and the diameters of the pressing plate 7, the rubber pad 8, and the sealing plate 10 match the inner diameter of the cylinder 6. A water inlet valve 12, an exhaust valve 13, a pressurizing mechanism 14, and a detection mechanism 15 are installed on the upper side wall of the cylinder 6 in sequence from left to right.

[0021] Specifically, a drain valve 16 is fixedly installed on the lower side edge position of the left side wall of the bottom box 1.

[0022] In this implementation, the drain valve 16 can drain the water in the bottom box 1 to avoid affecting subsequent detections.

[0023] Specifically, the lifting mechanism 5 includes an electric telescopic rod 501 and a fixing plate 502. The electric telescopic rod 501 is fixedly installed on the upper surface of the partition plate 3. The upper surface of the electric telescopic rod 501 is fixedly installed with a fixing plate 502, and the fixing plate 502 is fixedly connected to the side surface of the cylinder 6.

[0024] In this implementation, the electric telescopic rod 501 can drive the cylinder 6 to move up and down through the fixing plate 502. The cylinder 6 drives the pressing plate 7 to move up and down, and the pressing plate 7 can press the waterproof material to be detected.

[0025] Specifically, the lower surface of the cylinder 6 is horizontally flush with the lower surface of the pressing plate 7.

[0026] In this implementation, the pressing plate 7 fits tightly with the waterproof material and will not be hindered.

[0027] Specifically, the driving mechanism 9 includes a rotating shaft 901, a mechanical seal 902, a handle 903 and a switch mark 904. The rotating shaft 901 is installed on the upper side wall of the cylinder 6 through the mechanical seal 902. The upper surface of the rotating shaft 901 is fixedly connected to the upper surface of the sealing plate 10. The upper surface of the rotating shaft 901 is fixedly installed with a handle 903. Switch marks 904 are provided at the left side edge of the upper surface of the handle 903 and at the left side and front side positions of the upper surface of the cylinder 6.

[0028] In this implementation, the handle 903 drives the rotating shaft 901 to rotate in the mechanical seal 902. When the switch mark 904 on the upper surface of the handle 903 is vertically aligned with the switch mark 904 on the left side of the upper surface of the cylinder 6, it means that the pressing plate 7, the rubber pad 8 and the fan-shaped holes 11 on the sealing plate 10 are vertically aligned. When the switch mark 904 on the upper surface of the handle 903 is vertically aligned with the switch mark 904 on the front side of the upper surface of the cylinder 6, it means that the pressing plate 7 is misaligned with the fan-shaped holes 11 on the rubber pad 8 and the sealing plate 10, and the sealing plate 10 seals the fan-shaped holes 11 on the rubber pad 8 and the pressing plate 7.

[0029] Specifically, the pressurizing mechanism 14 includes an air pump 141, an air inlet pipe 142 and a check valve 143. The air pump 141 is fixedly installed on the upper surface of the cylinder 6. The air outlet of the air pump 141 is connected to the lower surface of the cylinder 6 through the air inlet pipe 142, and a check valve 143 is provided on the air inlet pipe 142.

[0030] In this implementation, the air pump 141 pressurizes the inside of the cylinder 6 through the air inlet pipe 142 to achieve the effect of adjusting the water pressure inside the cylinder 6, and the check valve 143 prevents gas from flowing back.

[0031] Specifically, the detection mechanism 15 includes a ranging sensor 151, a barometric pressure sensor 152, a controller 153, and an alarm 154. The ranging sensor 151 and the barometric pressure sensor 152 are embedded in the upper sidewall of the cylinder 6, the controller 153 is installed on the upper surface of the cylinder 6, and the alarm 154 is installed on the upper surface of the controller 153. The controller 153 is electrically connected to the ranging sensor 151, the barometric pressure sensor 152, and the alarm 154.

[0032] In this embodiment, the ranging sensor 151 monitors the initial position of the water surface in the cylinder 6. During the waterproof material test, when the distance between the ranging sensor 151 and the water surface in the cylinder 6 increases, it indicates that the water volume in the cylinder 6 decreases, which means the waterproof material leaks. The barometric pressure sensor 152 detects the air pressure in the cylinder 6. When the air pressure in the cylinder 6 decreases, it indicates that the water volume in the cylinder 6 decreases, that is, the waterproof material leaks, and the information is fed back to the controller 153. The controller 153 causes the alarm 154 to sound an alarm to remind the staff.

[0033] During use, place the waterproof material to be detected on the upper surface of the partition plate 3. The length and width of the waterproof material are greater than the diameter of the pressing plate 7. Drive the fixed plate 502 to move downward through the electric telescopic rod 501 in the lifting mechanism 5. The fixed plate 502 drives the cylinder 6 to move downward, and the cylinder 6 drives the pressing plate 7 to move downward, so that the pressing plate 7 presses tightly on the upper surface of the waterproof material. A waterproof sealing ring can be embedded on the lower surface of the pressing plate 7 to make the sealing effect between the pressing plate 7 and the upper surface of the waterproof material better. Connect the water inlet valve 12 to an external water pipe, and external water enters the cylinder 6. During the water injection process, the exhaust valve 13 is in an open state. After the water injection is completed, the exhaust valve 13 is closed. At this time, if the switch mark 904 on the upper surface of the handle 903 in the driving mechanism 9 is vertically aligned with the switch mark 904 on the front side of the upper surface of the cylinder 6, it means that the fan-shaped holes 11 on the pressing plate 7, the rubber pad 8 and the sealing plate 10 are vertically misaligned. The sealing plate 10 seals the fan-shaped holes 11 on the rubber pad 8 and the pressing plate 7, and the water in the cylinder 6 will not leak out. Therefore, it is necessary to make the handle 903 drive the rotating shaft 901 to rotate in the mechanical seal 902. When the switch mark 904 on the upper surface of the handle 903 is vertically aligned with the switch mark 904 on the left side of the upper surface of the cylinder 6, it means that the fan-shaped holes 11 on the pressing plate 7, the rubber pad 8 and the sealing plate 10 are vertically coincident. The water in the cylinder 6 contacts the waterproof material through the fan-shaped holes 11, and then the air pump 141 in the pressurizing mechanism 14 pressurizes the inside of the cylinder 6 through the air inlet pipe 142 to achieve the effect of adjusting the water pressure in the cylinder 6. Check whether there is water in the bottom box 1 through the observation window 2, that is, directly check the waterproof material. Then, the air pressure sensor 152 in the detection mechanism 15 detects the air pressure in the cylinder 6. When the air pressure in the cylinder 6 decreases, it means that the water volume in the cylinder 6 decreases, that is, the waterproof material leaks. The initial position of the water surface in the cylinder 6 is monitored by the distance measuring sensor 151. During the test of the waterproof material, when the distance between the distance measuring sensor 151 and the water surface in the cylinder 6 becomes larger, it means that the water volume in the cylinder 6 decreases, that is, the waterproof material leaks, and the information is fed back to the controller 153. The controller 153 makes the alarm 154 alarm to remind the staff, making the detection results diverse and the detection structure more accurate. After the detection is completed, the driving mechanism 9 resets the sealing plate 10, and the fan-shaped holes 11 on the sealing plate 10 are misaligned with the fan-shaped holes 11 on the rubber pad 8 and the pressing plate 7 to achieve the effect of sealing the water in the cylinder 6. There is no need to drain the detection water, and only a small amount of water in the fan-shaped holes 11 of the pressing plate 7 and the rubber pad 8 will be drained, saving the water injection and drainage process, improving work efficiency, and saving water resources.

[0034] In summary, the leak detection device for building waterproof materials has various leak detection methods such as the observation process and the detection mechanism 15 to check whether the waterproof material leaks, and can adjust the water pressure, making the detection results diverse and the detection structure more accurate. There is no need to drain the detection water, saving the water injection and drainage process, improving work efficiency, and saving water resources.
