DETAILED DESCRIPTION

[0017] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, but should not be understood as limiting the present invention.

[0018] The first embodiment of this application is:

[0019] See also Figure 1-Figure 2 ,in Figure 1 It is a schematic diagram of the overall structure of the first embodiment of the utility model; Figure 2 It is a structural diagram of the stabilizing component of the first embodiment of the present utility model.

[0020] The utility model provides a landfill anti-seepage membrane welding detection device: including a bottom plate 101, a detection box top plate 102, a suction fan 103 and a mobile detection mechanism, the mobile detection mechanism includes four universal wheels 104, an air clamp 105, an air inlet pipe 106, a detection seat 107, an air pressure detection component and a stabilization component, the air pressure detection component includes a pressure gauge 108 and a hollow probe 109, the stabilization component includes a placement rack 110, an adjustment frame 111 and four adjustment parts, the adjustment parts include a lifting sleeve 112, an adjustment stud 113 and a lifting foot 114. The above-mentioned solution solves the problems that the above existing technology can only detect narrower membranes, cannot be connected to other jet equipment and move, cannot detect large-scale anti-seepage membranes that have been laid, and has a small scope of application.

[0021] According to this specific embodiment, the top plate 102 of the detection box is fixedly arranged above the bottom plate 101, the suction fan 103 is fixedly arranged above the top plate 102 of the detection box, and the four universal wheels 104 are rotatably arranged below the bottom plate 101, the air clamp 105 is fixedly connected to the output end of the suction fan 103, and one end of the air inlet pipe 106 is sleeved on the output end of the suction fan 103, and the air pressure detection component is located at one end of the air inlet pipe 106. When testing the laid film, the device is moved by the four universal wheels 104 to reach the testing area, the air pressure detection component is installed at the testing location, and stabilized by the stabilizing component, and the suction fan 103 is started to transport air from the air inlet pipe 106 fixed by the air clamp 105 to the air pressure detection component, and the weld air pressure detection is performed on the target area. After the detection in this area is completed, the device is transported to the next detection area for continued use.

[0022] Among them, the detection seat 107 is fixedly connected to the air inlet pipe 106 and is located at one end away from the suction fan 103. The pressure gauge 108 is fixedly connected to the top of the detection seat 107. The hollow measuring needle 109 is fixedly connected to the detection seat 107 through a hose and is located on a side away from the air inlet pipe 106. The front end of the hollow measuring needle 109 is deflected and provided with a measuring hole. When performing inspection, the hollow measuring needle 109 is inserted into the inspection location until the measuring hole is passed through the inspection location, and the suction fan 103 is started. The airflow enters the detection seat 107 along the air inlet pipe 106 fixed by the air clamp 105, and then enters the hollow measuring needle 109 and is ejected from the measuring hole for inspection. At the same time, the pressure gauge 108 will display the air pressure of the airflow in real time so that the staff can judge the test results.

[0023] Secondly, the placement rack 110 is slidably connected to the bottom of the detection seat 107, and the adjustment frame 111 is fixedly connected to the bottom of the placement rack 110. Four adjustment parts are evenly distributed on the adjustment frame 111. Before detection, the four adjustment parts are adjusted according to the terrain. When the adjustment frame 111 is in a horizontal position, the placement rack 110 is stably located on the ground. After the placement rack 110 is placed steadily, the detection seat 107 is placed above the placement rack 110, so that the pressure gauge 108 can be checked more conveniently.

[0024] At the same time, the lifting sleeve 112 is fixedly connected to the bottom of the adjustment frame 111, the adjusting screw 113 is threadedly connected to the adjustment frame 111, and the lifting foot 114 is rotatably connected to the adjusting screw 113 and slidably connected to the lifting sleeve 112. When adjusting the adjusting member, the adjusting screw 113 is rotated, and the adjusting screw 113 drives the lifting foot 114 to move up and down along the lifting sleeve 112 until the height of the lifting foot 114 is appropriate.

[0025] When inspecting the laid membrane, since the area of ​​the membrane is large and the laying is completed, it is impossible to place the weld at the inspection location by moving the membrane, so it is necessary to move the inspection device to the target area for inspection, and at the same time implement certain stabilization measures for the inspection equipment to reduce the error of the inspection. The device is moved by the four universal wheels 104 to make the device reach the inspection area, and the hollow probe 109 is inserted into the inspection location until the measuring hole is passed through the inspection location. According to the terrain, the four adjusting studs 113 are rotated, and the four adjusting studs 113 respectively drive the four lifting feet 114 to move up and down along the four lifting sleeves 112 until the height of the lifting feet 114 is appropriate. At this time, the adjusting frame 111 is in a horizontal state, and the placement rack 110 is stably located on the ground. After the placement rack 110 is stabilized, the inspection seat 107 is placed above the placement rack 110, so that the pressure gauge 108 can be checked more conveniently and the suction fan 10 is started. 3. The airflow enters the detection seat 107 along the air inlet pipe 106 fixed by the air clamp 105, and then enters the hollow measuring needle 109, and is ejected from the measuring hole for detection. At the same time, the pressure gauge 108 will display the air pressure of the airflow in real time so that the staff can judge the detection results, start the suction fan 103, and transport the air from the air inlet pipe 106 fixed by the air clamp 105 to the air pressure detection component to perform weld air pressure detection on the target area. The air clamp 105 clamps the air inlet pipe 106 on the output end of the suction fan 103, which can effectively prevent the air inlet pipe 106 from falling off. After the detection in this area is completed, the device can be transported to the next detection area for continued use, avoiding the problem that the existing technology can only detect narrow membranes, cannot be connected to other jet equipment and moved, cannot detect large-scale anti-seepage membranes that have been laid, and has a small scope of application. The effect of detecting the laid membrane and improving the scope of application of the device is achieved.
