Description

Technical Field

[0001] The utility model relates to a fixing device, in particular to a covering film fixing device for a city garbage landfill, belonging to the technical field of covering film fixing. Background Art

[0002] Urban landfills are facilities dedicated to the disposal of urban solid waste. They are an important part of the urban waste management system. Sanitary landfills are widely used in China because of their low cost and good hygiene. They are usually a site for storing garbage, where garbage is piled and compacted. Over time, landfills may produce greenhouse gases such as methane and carbon dioxide. In order to prevent the gas generated by the decomposition of garbage from overflowing or to prevent rainwater and other liquids from penetrating, it is often necessary to cover the landfill with a covering film. In order to prevent the covering film from being blown away by the wind, sandbags, stones or pressing plates are usually used to cover the covering film.

[0003] A Chinese patent publication (publication number: CN207357761U) discloses a reusable landfill covering film pressing device, which belongs to the technical field of covering film pressing products, including a nail body and a gland, wherein the nail body includes a nail rod and a nail cap, wherein the nail cap is arranged at one end of the nail rod, wherein a first adsorption member is arranged on a side of the nail cap away from the nail rod, wherein a second adsorption member is arranged on the gland, wherein the second adsorption member is fixed to the first adsorption member by a magnetic adsorption force, wherein a first fluorescent coating is arranged on the surface of the nail cap and / or the surface of the first adsorption member, and a second fluorescent coating is coated on the surface of the gland, wherein the nail body and the nail cap are simple in structure, low in manufacturing cost, convenient in use, small in size, light in weight, and a staff member can carry multiple nail bodies and glands at one time, thereby greatly reducing labor intensity, improving work efficiency, and having good market promotion and application value;

[0004] The film pressing device fixes the top cover and the nail body together by adsorbing the first adsorbent and the second adsorbent. However, the stability of this fixing method is poor when used, and the covering film is easily lifted, thereby causing the landfill gas to diffuse and pollute the air. Therefore, a covering film fixing device for urban landfills is proposed. Utility Model Content

[0012] The embodiment of the utility model has the following advantages due to the adoption of the above technical solution:

[0013] 1. The utility model effectively prevents the circular ring from moving upward due to accidental touch and the sharp block from puncturing the glue storage bag by providing a limit rod.

[0014] 2. The utility model uses a pressing plate, a fixing nail, a circular ring, a rubber ring, a sharp block, and a glue storage bag to press down and rotate the pressing plate. The pressing plate drives the circular column and the fixing nail to move downward. The circular column moves downward and drives the circular ring to move downward at the same time. When the bottom of the circular ring contacts the covering film, the pressing plate continues to be pressed downward to make the circular ring move upward. The upward movement of the circular ring also drives multiple sharp blocks to move upward and puncture the glue storage bag. At this time, the glue flows out to bond the lower surface of the pressing plate to the upper surface of the covering film, so that the covering film can be quickly fixed and the pressing plate and the covering film can be pasted together, effectively preventing rainwater or other liquids from seeping in.
