AI Technical Summary
The existing manhole cover has poor sealing effect, which leads to the easy leakage of harmful gases or liquids inside the shaft and the easy flow of external pollutants.
A sealing heavy duty manhole cover is designed. By opening a rubber sealing groove on the upper side wall of the well frame and setting a rubber sealing ring on the lower side wall of the manhole cover, the sealing effect between the manhole cover and the well frame is enhanced by adapting the rubber sealing ring and the sealing groove after the engagement.
Effectively isolate harmful gases or liquids inside the shaft, while preventing the inflow of external contamination sources, significantly improving the sealing performance of the manhole cover.

Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of well covers, in particular to a hermetic heavy-duty well cover. Background Art
[0002] A well cover is a closure at the top of the entrance to underground facilities, generally used to cover roads or deep wells at home to prevent people or objects from falling. Well covers are provided on the ground in some chemical industrial zones, oil pollution treatment centers, and storage areas containing hazardous chemicals.
[0003] However, the following technical problems still exist in the existing well covers during use:
[0004] The existing well covers have poor sealing effects. There is a lack of rubber sealing materials at the installation position with the wellhead, so harmful gases and liquids inside the wellbore are likely to leak, and external pollutants are also likely to flow into the inside of the wellbore.
[0005] Therefore, a hermetic heavy-duty well cover is proposed to solve the above-mentioned problems. Content of the Utility Model
[0006] The purpose of the utility model is to provide a hermetic heavy-duty well cover to solve the problems mentioned in the above background art.
[0007] To achieve the above purpose, the utility model provides the following technical solution: A hermetic heavy-duty well cover includes a well frame and a well cover. The well cover is snap-fitted inside the well frame. Reinforcing strips are evenly arranged on the lower sidewall of the well cover. Reinforcing support plates are evenly arranged on the edge of the upper sidewall of the well frame. A rubber sealing groove is formed on the inner wall of the well frame. A rubber sealing ring is fixedly connected to the lower sidewall of the well cover corresponding to the rubber sealing groove. The rubber sealing ring is adapted to the rubber sealing groove. Hermetic lifting holes are symmetrically arranged on the upper sidewall of the well cover. Well cover opening lifting holes are symmetrically arranged on the sidewall of the well frame.
[0008] Preferably, a project name label is arranged at the front end of the upper sidewall of the well cover.
[0009] Preferably, a medium name is arranged at the rear end of the project name label.
[0010] Preferably, a medium code is arranged at the rear end of the medium name.
[0011] Preferably, evenly arranged anti-slip cross patterns are arranged on the upper sidewall of the well cover.
[0012] Compared with the prior art, the beneficial effects of the utility model are:
[0013] In this application, a rubber sealing groove is opened on the upper side wall of the well frame, and a rubber sealing ring is provided on the lower side wall of the well cover. After the well cover is engaged with the well frame, the rubber sealing ring is adapted to the rubber sealing groove, increasing the sealing effect between the well cover and the well frame, effectively isolating the harmful gases or liquids inside the well from leaking out, and at the same time preventing external pollution sources from flowing into the inside of the well.

DETAILED DESCRIPTION OF THE EMBODIMENTS
[0018] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0019] In the description of the present utility model, it should be understood that the orientation or positional relationship indicated by the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc. is based on the orientation or positional relationship shown in the accompanying drawings, and is only for the convenience of describing the present utility model and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the present utility model.
[0020] Embodiment:
[0021] Please refer to Figures 1-3 , the present utility model provides a technical solution:
[0022] A hermetic heavy manhole cover, comprising a manhole frame 1 and a manhole cover 2. The manhole cover 2 is snap-fitted inside the manhole frame 1. The lower sidewall of the manhole cover 2 is provided with evenly arranged reinforcing bars 3. The upper sidewall edge of the manhole frame 1 is provided with evenly arranged reinforcing support plates 4. The inner wall of the manhole frame 1 is provided with a rubber sealing groove 5. The lower sidewall of the manhole cover 2 is fixedly connected with a rubber sealing ring 6 corresponding to the rubber sealing groove 5. The rubber sealing ring 6 is adapted to the rubber sealing groove 5. The upper sidewall of the manhole cover 2 is provided with symmetrical hermetic lifting holes 7. The sidewall of the manhole frame 1 is provided with symmetrical manhole cover opening lifting holes 8, which is convenient to open the upper manhole cover 2 through a lever. In this application, a rubber sealing groove 5 is opened on the upper sidewall of the manhole frame 1, and a rubber sealing ring 6 is arranged on the lower sidewall of the manhole cover 2. After the manhole cover 2 is snap-fitted with the manhole frame 1, the rubber sealing ring 6 is adapted to the rubber sealing groove 5, increasing the sealing effect between the manhole cover 2 and the manhole frame 1, which can effectively isolate the harmful gases or liquids inside the well channel from leaking, and at the same time prevent external pollution sources from flowing into the inside of the well channel.
[0023] At the front end of the upper sidewall of the manhole cover 2, there is a project name label 9. At the rear end of the project name label 9, there is a medium name 10. At the rear end of the medium name 10, there is a medium code 11. The project name label 9, the medium name 10, and the medium code 11 can all be changed accordingly according to needs during production and processing.
[0024] The upper sidewall of the manhole cover 2 is provided with evenly arranged anti-slip cross patterns 12, which can increase the anti-slip effect on the upper surface of the manhole cover. If there are pedestrians or vehicles on the upper end, it is not easy to slip.
[0025] Working principle:
[0026] The manhole frame 1 is fixedly connected to the wellhead through cement concrete. The manhole cover 2 is snap-fitted inside the manhole frame 1. By snap-fitting the rubber sealing ring 6 with the rubber sealing groove 5, the sealing effect between the manhole cover 2 and the manhole frame 1 is increased, ensuring that the harmful gases or liquids inside the well channel do not leak, and it can also ensure that external pollutants do not enter the inside of the well channel through the gap between the manhole cover 2 and the manhole frame 1.
[0027] The above shows and describes the basic principles, main features and advantages of the present invention. For those skilled in the art, it is obvious that the present invention is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the present invention.
