Description

Technical Field

[0001] The utility model relates to the technical field of manhole covers, in particular to a lifting grass-planting manhole which is easy to open. Background Art

[0002] With the acceleration of urbanization, urban ecological and environmental problems have become increasingly prominent. How to create a green, fresh and natural ecological environment in the city has become the focus of people's attention. Among them, the design of traditional manhole covers often ignores the coordination with the surrounding environment, affecting the beauty and greening effect of the city. Therefore, the technology of planted grass wells came into being, aiming to achieve harmonious coexistence between the manhole cover and the surrounding environment through innovative design, and to improve the level of urban greening. At present, the commonly used invisible manhole covers with planted grass are generally made of polymer composite materials (such as composite resin, SMC resin, etc.), which have the advantages of light weight, high strength, corrosion resistance, and good weather resistance. Among them, the invisible manhole covers with planted grass in the prior art usually include two parts: a base and a cover body. The cover body is provided with a groove for planting vegetation, and the base plays a supporting and fixing role. The planted grass well can be integrated with the surrounding environment. Although this kind of manhole cover solves the coordination problem between the manhole cover and the surrounding environment in the greening to a certain extent. However, due to the filling of soil in the middle of this manhole cover, the weight of the manhole cover increases, which is not conducive to maintenance personnel to open it. For example, the Chinese utility model publication number CN218204574U, entitled "A Green Belt Concave Grass Manhole Cover Structure," and the Chinese utility model publication number CN210086311U, entitled "A Grass Manhole Cover." Furthermore, to ensure easy opening for maintenance, tall plants cannot be planted, requiring only low herbaceous layers, which can easily undermine the overall aesthetics of the plant landscape.

[0003] Therefore, it is urgent to propose a lifting grass-planting well with simple structure and convenient opening. Utility Model Content

[0026] like Figures 1 to 2 As shown, this embodiment provides a liftable grass well that is easy to open, comprising a base 1 embedded in the wellhead, a cover 2 covering the base 1, a first lift support mechanism 3 and a second lift support mechanism 4 disposed between the base 1 and the cover 2 to support the cover 2, and a transverse support rod 5 disposed between the first lift support mechanism 3 and the second lift support mechanism 4. A well cover receiving slot 11 is provided at the top of the base 1, and the cover 2 is received in the well cover receiving slot 11. In addition, several handles 21 are provided around the upper portion of the cover 2.

[0027] In this embodiment, to achieve convenient and reliable opening, the first lifting support mechanism 3 and the second lifting support mechanism 4 have the same structure and are linked to each other by a transverse support rod 5. Taking the first lifting support mechanism 3 as an example, it includes a lower support beam 31 fixed to the inner wall of the base 1, a support rod 32 pivotally connected to the lower support beam 31 at its lower portion, a slide rail 34 pivotally connected to the upper portion of the support rod 32, a first damping rod 33 pivotally connected to the lower support beam 31 at its lower portion and to the slide rail 34 at its top portion, a first support arm 35 pivotally connected to the lower support beam 31 at its lower portion, a second support arm 36 pivotally connected to the lower support beam 31 at its lower portion and connected to the first support arm 35 at its top portion, and supporting the first support arm 35, a first crank arm 37 pivotally connected to the top of the first support arm 35 at its middle portion and to the rear end of the slide rail 34 at its front end, and a second damping rod 38 pivotally connected to the middle of the first support arm 35 at its bottom and to the rear end of the first crank arm 37 at its top portion. The slide rail 34 is fixed on the bottom of the cover 2 .

[0028] When the cover body 2 is closed and stored in the manhole cover storage groove 11, the first damping rod 33 and the second damping rod 38 are in a compressed state. When the cover body 2 needs to be opened, the handle 21 is pulled, and the first damping rod 33 and the second damping rod 38 push the slide rail 34 to move upward and lift the slide rail 34. In the process of lifting the slide rail 34, the support rod 32 is converted from an inclined state to a vertical state, and supports the slide rail 34. After the slide rail 34 rises to the top, pull the handle 21 to unfold the slide rail 34 and expose the hollow inside the base 1. It should be noted here that the slide rail 34 of this embodiment is a two-section or three-section type, which is an existing mature product.
