[0001] The utility model relates to the technical field of landfill detection, in particular to a self-detection device for an anti-seepage layer of a domestic garbage landfill. Background Art

[0002] The anti-seepage layer of the domestic waste landfill is an important part of the anti-seepage system of the landfill. Its main function is to block the leachate in the landfill by laying low-permeability materials in the landfill, prevent it from migrating to the environment outside the landfill, and block surface water and groundwater from entering the landfill. This helps to reduce the generation of leachate and is conducive to the collection of landfill gas, thereby preventing landfill gas and leachate from polluting the environment.

[0003] At present, after the anti-seepage layer is installed, it is generally inspected. The electric spark method is generally used for inspection. However, the current electric spark detectors lack effective carriers and need to be carried manually when used. In addition, the detector needs to be held handheld to scan the weld during inspection. These operations have increased the workload of the inspectors and affected the inspection results. Summary of the invention

[0004] The technical problem to be solved by the utility model is to provide a self-detection device for the anti-seepage layer of a domestic waste landfill, which reduces the volume by folding and is convenient to carry.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.

[0018] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.

[0019] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.

[0020] like Figure 1 , Figure 2 and Figure 3 As shown, the utility model is a self-detection device for the anti-seepage layer of a domestic waste landfill, comprising a detector 1 for detecting the anti-seepage layer, a plurality of outer tubes 2 are installed on the outside of the detector 1, a plurality of support rods 7 are installed on the outside of the outer tubes 2 through torsion springs, a universal wheel 8 is installed on the end of the support rods 7 away from the outer tubes 2, a ring body 10 is sleeved on the outside of the outer tube 2, a groove is provided on the bottom surface of the ring body 10 opposite to the support rod 7, a compression spring is installed inside the groove, a push rod 6 is installed on the other end of the compression spring, the other end of the push rod 6 passes through the groove and is arranged to abut against the support rod 7, and a positioning ring 11 for pressing down the support rod 7 is installed on one end of the ring body 10.

[0021] Among them, the universal wheel can be replaced with a motor wheel, and the motor wheel can automatically drive the movement of the device, thereby further achieving a convenient effect.

[0022] In this embodiment, the positioning ring 11 is sleeved on the outside of the outer tube 2 and is arranged above the ring body 10. The lower end of the positioning tube 5 is expanded outward to form a connecting tube 4. The connecting tube 4 is sleeved on the outside of the ring body 10. A positioning groove with an annular structure is provided on the inner ring surface of the connecting tube 4. The positioning ring 11 is installed on the outer ring surface of the ring body 10, and the positioning ring 11 is movably arranged in the positioning groove.

[0023] In this embodiment, a first external thread is provided on the outer wall surface of the upper opening of the outer tube 2, a second external thread is provided near the ring body 10 of the outer tube 2, and an internal thread is provided on the inner ring surface of the positioning tube 5. The positioning tube 5 is meshed and connected with the second external thread on the outer tube 2 through the internal thread.

[0024] In this embodiment, a limiting groove 3 is vertically provided on the outer wall surface of the outer tube 2, and the inner ring surface of the ring body 10 protrudes opposite to the limiting groove 3 to form a limiting portion, and the limiting portion is slidably arranged in the limiting groove 3, so that the ring body can only move up and down along the limiting groove, so that the push rod can always be opposite to the support rod.

[0025] In this embodiment, the inner ring surface of the ring body 10 is arranged in contact with the outer ring surface of the outer tube 2, so that the ring body can fully contact the outer tube, avoiding tilting and placement, and increasing stability.

[0026] In this embodiment, a retreat space for the push rod 6 to move upward is formed between the top surface of the push rod 6 and the top surface of the groove, so that the push rod can move upward and squeeze the compression spring.

[0027] When in use, the positioning tube can be directly rotated. Since the middle section of the outer tube is a smooth structure, the positioning tube can quickly pass through the middle of the outer tube until it is meshed and connected with the second external thread. The movement of the positioning tube synchronously drives the connecting tube and the ring body. The movement of the ring body drives the push rod. The descending push rod can press down the support rod, so that the support rod rotates downward with the torsion spring hinge as the center until the universal wheel contacts the ground. The detector can be centered through the support rod, the universal wheel and the outer tube without the need to hold or carry it.

[0028] When passing through an uneven anti-seepage layer, the corresponding universal wheel will drive the support rod to lift up, and the rotation of the support rod will drive the top rod, which can squeeze the compression spring, and the compression spring can play the role of weight reduction;

[0029] On the contrary, when not in use, the positioning tube can be rotated upward, and the movement of the positioning tube synchronously drives the ring body, so that the ring body moves upward along the limiting groove until the positioning tube is engaged with the first external thread on the outer tube, thereby fixing the moved positioning tube;

[0030] After the squeezing force from the push rod is lost, the support rod and the universal wheel can be automatically lifted upward by the torsion of the torsion spring hinge until the support rod is folded against the outer tube, thereby greatly reducing the volume of the device.

[0031] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
