Description

Technical Field

[0001] The utility model relates to the technical field of film-through-pipe sealing, in particular to a HDPE film-through-pipe quick sealing component. Background Art

[0002] Due to its good chemical corrosion resistance and waterproof performance, HDPE membrane is often used as the cover layer of landfills, playing the role of anti-seepage and isolation in landfill to prevent garbage leakage and groundwater pollution. HDPE membrane pipe penetration refers to the process or technology of opening penetration holes or channels on the HDPE membrane. This operation is usually used in occasions where ventilation, drainage or other pipeline guidance is required under the membrane cover.

[0003] Application No. 202122491171.7 discloses an anti-seepage geomembrane pipe seal, comprising a first sleeve, a second sleeve, a third sleeve and a fourth sleeve which are sleeved on an engineering pipeline and connected in sequence by threads; a pipe sealing rubber ring is provided at the threaded connection between the first sleeve and the second sleeve; a pipe sealing rubber ring is provided at the threaded connection between the third sleeve and the fourth sleeve; the outer walls of the second sleeve and the third sleeve are respectively provided with a first membrane clamping annular wing and a second membrane clamping annular wing for clamping the anti-seepage geomembrane, and the first membrane clamping annular wing and the second membrane clamping annular wing are provided with 1-3 annular grooves on the surface of the anti-seepage geomembrane, and a geomembrane sealing rubber ring is half-embedded in each annular groove. It has a simple structure and good sealing effect.

[0004] However, the above structure has the following disadvantages: since the third sleeve and the fourth sleeve are threadedly connected, when the first membrane clamping ring wing and the second membrane clamping ring wing are close to the anti-seepage geomembrane, the anti-seepage geomembrane will be driven to rotate when tightened, causing wrinkles, affecting the flatness of the geomembrane and reducing the sealing effect.

[0005] Therefore, we propose a HDPE film pipe penetration quick seal to solve the above problems. Utility Model Content

[0006] 1. Technical issues to be solved

[0007] In view of the deficiencies of the prior art in the above background technology, the purpose of the utility model is to provide a HDPE film pipe penetration quick seal to solve the problems raised in the above background technology.

[0008] (II) Technical solution

[0011] The fixing mechanism includes a sliding sleeve which is slidably mounted on the outside of the sleeve and a locking sleeve which is threadedly connected to one end of the positioning sleeve. A wing plate is provided at one end of the sliding sleeve close to the HDPE film. A plurality of reinforcing plates are arranged in a circumferential array on the side wall of the sliding sleeve. One end of the reinforcing plate is fixed to the wing plate, and the other end abuts against the locking sleeve when the locking sleeve is tightened on the sleeve.

[0012] Furthermore, a first sealing component is provided between the positioning sleeve and the locking sleeve, the first sealing component comprises a constriction opening of the inner wall of the locking sleeve that converges inwardly, and a first sealing rubber ring is provided between the constriction opening and the end of the positioning sleeve.

[0013] Furthermore, a second sealing assembly is provided between the positioning sleeve and the sliding sleeve, and the second sealing assembly includes a convex plate fixed to the end wall of the locking sleeve, and a groove adapted to the convex plate is provided at one end of the sliding sleeve away from the locking sleeve, and a second sealing rubber ring is provided between the convex plate and the groove.

[0014] Furthermore, a third sealing component is arranged on the wing plate, and the third sealing component includes a third sealing rubber ring. A sealing groove for embedding the third sealing rubber ring is opened at one end of the wing plate close to the HDPE film.

[0015] Furthermore, the reinforcing plate is in a right-angle trapezoidal structure, and the length of the reinforcing plate close to the wing plate is greater than the length of the reinforcing plate close to the locking sleeve.

[0016] (III) Beneficial effects

[0017] Compared with the prior art, the beneficial effects of the utility model are:

[0018] By setting a positioning sleeve and a fixing mechanism between the pipe hole of the HDPE membrane and the engineering pipeline, the sliding sleeve in the fixing mechanism moves toward the HDPE membrane and is clamped under the push of the locking sleeve, and sealing is achieved through the first sealing component, the second sealing component and the third sealing component. Compared with the above-mentioned scheme, the wing plate is slidably clamped when clamping and sealing the HDPE membrane, and will not cause wrinkles in the HDPE membrane, so as to improve the flatness of the HDPE membrane. At the same time, a reinforcement plate is added, and the locking sleeve is pressed and fixed on the peripheral side of the wing plate through the reinforcement plate when tightened, so as to prevent the sealing from being reduced due to the warping of the edge of the wing plate.
