Detailed Implementation

[0034] Please refer to the attached document. Figures 1-6 This application illustrates a temporary sealing device for rainwater well openings provided in an embodiment of the present application. During municipal road construction or emergency repairs, rainwater well openings often need to be temporarily sealed to prevent foreign objects from falling or people from falling in. Specifically, it includes a plastic cover 1, a support rib 2, a sealing positioning element 4, and a sealing ring 5.

[0035] The plastic cover 1 is injection molded from high-density polyethylene (HDPE) or glass fiber reinforced polypropylene (PP+30%GF) with a thickness of 12±0.5mm. The resulting plastic cover 1 is lightweight, making it easy to carry and handle. A support rib 2 is fixedly installed at the bottom of the plastic cover 1 to increase structural strength and improve compressive strength. An annular part is formed at the bottom of the plastic cover 1 outside the support rib 2. A sealing positioning element 4 is fixedly connected to the annular part at the bottom of the plastic cover 1. A sealing ring 5 is set at the bottom of the sealing positioning element 4 to keep the sealing ring 5 stable and prevent it from moving during use. Generally, a stepped sealing groove is set at the bottom of the sealing positioning element 4. The sealing ring 5 is made of ethylene propylene diene monomer (EPDM) rubber with a trapezoidal cross section and is embedded in the stepped sealing groove at the bottom of the sealing positioning element 4. The compression rate is 18% to 22%, achieving a high-efficiency sealing effect.

[0036] The downward height of the support rib 2 is greater than the overall downward height of the sealing positioning element 4 and the sealing ring 5. Thus, the support rib 2 protrudes downward. When installing the temporary sealing device, the downward protruding part of the support rib 2 is inserted into the wellhead to form a positioning structure and prevent the temporary sealing device from moving horizontally. The sealing ring 5 is aligned with the step of the wellhead to form a sealing structure.

[0037] This application uses a plastic cover 1 as the main body, which is lightweight, corrosion-resistant, and easy to carry and transport. Support ribs 2 are designed to increase structural strength and improve compressive strength, giving it sufficient load-bearing capacity and preventing deformation. A sealing positioning element 4 and a sealing ring 5 are also designed. When installing the temporary cover device, the sealing ring 5 is aligned with the step of the well opening to form a sealing structure, effectively preventing foreign objects from falling or personnel from falling in. Furthermore, the downward height of the support rib 2 is greater than the overall downward height of the sealing positioning element 4 and the sealing ring 5, so that the support rib 2 protrudes downwards. When installing the temporary cover device, this protruding part of the support rib 2 is inserted into the well opening to form a positioning structure, preventing horizontal movement of the temporary cover device and ensuring its stability after installation.

[0038] The shape and size of the plastic cover 1 are designed based on the shape and size of existing wellheads, such as a disc-shaped structure with a diameter adapted to standard wellheads (Φ600 / Φ800 / Φ1000mm).

[0039] In one embodiment, the support rib 2 includes: transverse support ribs 201 and longitudinal support ribs 202 that are vertically intersecting. The grid-shaped structure formed by the interlacing of the transverse support ribs 201 and longitudinal support ribs 202 has stronger structural strength.

[0040] The sides of the transverse support rib 201 and the longitudinal support rib 202 are equipped with sleeve parts 3. The sleeve parts 3 are components that directly contact the inner wall of the rainwater well opening on the sides of the transverse support rib 201 and the longitudinal support rib 202, and can effectively protect the sides of the transverse support rib 201 and the longitudinal support rib 202.

[0041] In one embodiment, the sleeve member 3 includes: a main body 301, a horizontal plate 302, and a long screw 303.

[0042] A guide opening 301a is provided at the bottom of the main body 301 on the side away from the transverse support rib 201 or the longitudinal support rib 202. The guide opening 301a is oblique or arc-shaped to facilitate the insertion of the bottom of the main body 301 into the inside of the rainwater well opening. A latch 301b is provided on the side of the main body 301 near the transverse support rib 201 or the longitudinal support rib 202. The latch 301b is engaged with the side of the transverse support rib 201 or the longitudinal support rib 202. A horizontal plate 302 is fixedly provided inside the latch 301b of the main body 301. A through hole 302a is provided on the upper part of the horizontal plate 302. A long screw 303 is provided at the through hole 302a of the horizontal plate 302. The top end of the long screw 303 is threadedly connected to the bottom of the transverse support rib 201 or the longitudinal support rib 202. The bottom end of the long screw 303 and the bottom of the transverse support rib 201 or the longitudinal support rib 202 form a sliding section for the horizontal plate 302 to slide. After the long screw 303 is installed, the main body 301 and the horizontal plate 302 can slide up and down within the sliding section, but will not detach from the transverse support rib 201 or the longitudinal support rib 202.

[0043] By designing the main body 301, it encloses the outer edge of the transverse support rib 201 or the longitudinal support rib 202. During installation, the outer side of the main body 301 contacts the inner wall of the rainwater well opening, thus protecting the transverse support rib 201 or the longitudinal support rib 202. Furthermore, the installation structure using long screws 303 allows the main body 301 and the horizontal plate 302 to slide up and down relative to the transverse support rib 201 or the longitudinal support rib 202 a certain distance. During installation, the bottom of the plastic cover 1 can abut against the main body 301 and move downwards along with the transverse support rib 201 or the longitudinal support rib 202 (the main body 301...). With the transverse support rib 201 or longitudinal support rib 202 in an upper position, the main body 301 is tightly connected to the transverse support rib 201 or longitudinal support rib 202 to ensure stability during installation. When disassembling, the transverse support rib 201 or longitudinal support rib 202 can be opened upwards, and the main body 301 moves downwards relative to the transverse support rib 201 or longitudinal support rib 202 by a certain distance (the main body 301 is in a lower position relative to the transverse support rib 201 or longitudinal support rib 202), making the stability of the main body 301 and the transverse support rib 201 or longitudinal support rib 202 poor, and the main body 301 is easy to deform and disassemble.

[0044] In one embodiment, a plurality of radially distributed reinforcing ribs 6 are fixedly connected to the top of the plastic cover 1. The reinforcing ribs 6 are used to increase the strength of the plastic cover 1 and form an anti-slip texture on the top of the plastic cover 1.

[0045] In one embodiment, a lifting handle 7 is installed on the top of the plastic cover 1. The lifting handle 7 plays an auxiliary role when installing and removing the temporary sealing device, that is, the user manipulates the plastic cover 1 by lifting the handle 7.

[0046] In one embodiment, the lifting handle 7 includes: a rod 702, a circular hole is provided on the upper surface of the plastic cover 1, the rod 702 slides inside the circular hole, a lifting end 701 is fixedly connected to the top end of the rod 702, and a limit end block 703 is fixedly connected to the bottom end of the rod 702.

[0047] When the lifting handle 7 is not in use, the rod 702 slides down to the lowest point under the influence of gravity, that is, the lifting end 701 is attached to the upper surface of the plastic cover 1, so that the lifting handle 7 does not protrude too much and obstruct pedestrians and vehicles. When in use, the lifting handle 7 can be pulled upward, that is, the rod 702 slides upward to the uppermost point, and the limiting end block 703 abuts against the lower surface of the plastic cover 1, and the lifting end 701 is formed in a form that is easy for the user to grasp.
