Background technique

Sewer manhole covers are often designed and used in water supply and drainage systems, and are used in inspection wells, valve wells, sewage wells and other places where vertical wells are required, especially on municipal roads under construction, where temporary drainage systems are often required. Drainage, but the manhole covers in these places are often stolen by criminals, and the wellheads without the cover of the manhole cover will directly endanger pedestrians with unknown road conditions. Therefore, it is necessary to design a kind of temporary construction that can effectively prevent theft and ensure normal use. Special manhole cover, for which we propose an anti-theft road construction manhole cover.

Utility model content

The purpose of this utility model is to provide a kind of anti-theft road construction manhole cover, in order to solve the problem that the sewer manhole cover is often designed and used in the water supply and drainage system, and other problems such as inspection wells, valve wells and sewage wells that need to be set up vertical wells. All places must be used, especially on municipal roads under construction, where temporary drainage systems are often required for water supply and drainage. However, manhole covers in these places are often stolen by lawbreakers, and wellheads that are not covered by manhole covers will directly endanger unknown road conditions. Therefore, it is necessary to design a special manhole cover that can effectively prevent theft during temporary construction and ensure normal use.

In order to achieve the above purpose, the present invention provides the following technical solutions: an anti-theft manhole cover for road construction, comprising a cover body, the bottom of the cover body is welded with a base, and the middle part of the inner cavity of the cover body is laterally clamped through a card slot. There is a barrier net, an opening and closing cover top is welded on the top of the cover body, and a rotating shaft sleeve is arranged at the right end connection of the upper and lower covers of the opening and closing cover top, and a handle is welded on the left end of the top of the opening and closing cover top. The middle part of the handle and the left side of the opening and closing cover are correspondingly provided with screw holes, and the screw holes are connected with locking bolts through threads. The top edge of the cover top is evenly provided with drainage holes, and the drainage holes on top of the barrier net.

Preferably, the middle part of the cover body is provided in a concave arc shape, and the diameter of the concave part is smaller than the diameter of the base and the opening and closing cover top.

Preferably, the mesh diameter of the barrier net is 5-10 cm.

Preferably, the handle is a flat hollow handle, and the handle and the locking bolt are perpendicular to each other.

Compared with the prior art, the beneficial effects of the present utility model are as follows: in this new scheme, the base is buried at the mouth of the sewer, the inner concave is filled with fillers such as asphalt, the closed lid is placed on the top of the sewer, and a locking device is used. It can be fixed by bolts. When maintenance is required, loosen the locking bolts and remove the end cover to perform operation and maintenance. The structure is simple, the use is convenient, and it is both anti-theft and practical.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to 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 implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Please refer to Figures 1-3, the present utility model provides a technical solution for an anti-theft road construction manhole cover: an anti-theft road construction manhole cover, comprising a cover body 1, the diameter of the inner recess in the middle of the cover body 1 is smaller than that of the base 2 and the opening and closing The diameter of the cover top 4 makes it more stable to be clamped in the installation groove of the sewer. The bottom of the cover body 1 is welded with the base 2, and the middle of the inner cavity of the cover body 1 is horizontally clamped through the card slot. The net 3 can also prevent objects from falling when the opening and closing cover 4 is opened while maintaining the normal flow of water. A rotating shaft sleeve is provided, through which the end cover of the opening and closing cover 4 can be freely opened, and a handle 5 is welded on the left end of the top of the opening and closing cover 4. The handle 5 can facilitate the operation of the opening and closing cover 4. The handle The middle part of 5 and the left side of the opening and closing cover 4 are correspondingly provided with screw holes, and the screw holes are connected with locking bolts 6 through threads. Through the locking bolts 6, the opening and closing cover 4 can be fastened and fixed. The top edge of the opening and closing cover 4 is evenly provided with drainage holes 7, and the drainage holes 7 are located on the top of the barrier net 3. The drainage holes 7 guide the water flow into the cover body 1, and finally discharge into the sewer.

Wherein, the middle part of the cover body 1 is arranged in a concave arc shape, and the diameter of the inner recess is smaller than the diameter of the base 2 and the opening and closing cover 4, the mesh diameter of the barrier net 3 is 5-10cm, and the handle 5 is a flat hollow The handle, the flat hollow handle can be kept parallel to the ground after installation to avoid tripping pedestrians, and the handle 5 and the locking bolt are perpendicular to each other.

Working principle: When this scheme is in use, the cover body 1 is placed at the manhole cover of the sewer, and the inner recess is filled with fillers such as asphalt or cement. The base 2 is placed under the sewer, and then the locking bolt 6 is used. Tighten the end cover of the opening and closing cover 4, loosen the locking bolt 6 to open the end cover during maintenance, and the water flow will flow into the inner cavity of the cover body 1 through the drainage hole 7 and then drain into the sewer. The manhole cover can effectively prevent illegal personnel from stealing, and at the same time, frequent maintenance of the sewer is required in the construction environment. This solution can be quickly opened for maintenance, and can also be quickly installed after use, which is very convenient.

Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes and modifications can be made to these embodiments without departing from the principles and spirit of the present invention , alternatives and modifications, the scope of the present invention is defined by the appended claims and their equivalents.
