Description

Technical Field

[0001] This utility model relates to the field of water supply and drainage technology, and more specifically to a new type of protective net for water supply and drainage well covers. Background Technology

[0002] Drainage manhole covers are sealed structures installed on top of entrances and exits from the ground surface to underground facilities, used to allow rainwater or domestic drainage to flow through. Because they are installed on the road surface, drainage manhole covers are easily damaged by the constant pressure of passing vehicles and are frequently stolen, leading to frequent incidents of pedestrians falling into them.

[0003] Currently, there are two types of manhole cover protective nets: one is a soft rope woven net, and the other is a metal mesh. As the soft rope woven net is used for a long time, it will gradually rot and decompose under the erosion of rainwater. If someone accidentally falls into the manhole, the soft rope woven net may break. Although the metal mesh does not have the problem of rotting and decomposition, it needs to be reinforced and locked in order to prevent theft. This means that workers need to disassemble the mesh to go down into the manhole, which increases the work process. Moreover, if the manhole cover is stolen, pedestrians may accidentally step into the mesh and get injured, such as spraining their ankles, due to the height difference. Utility Model Content

[0004] One advantage of this utility model is that it provides a new type of protective net for water supply and drainage well covers.

[0024] The first embodiment of this utility model is as follows:

[0025] A new type of water supply and drainage well cover 11 protective net includes a woven net. The main body of the woven net is made of expanded polyester woven into the inside. Fine steel wire rope 5 is embedded in the inside while weaving to enhance the overall tensile strength. At the same time, it can still maintain strong tensile strength after long-term use and corrosion. The whole is soft, so when pedestrians accidentally fall into the water supply and drainage well, they will not suffer sprains or other injuries.

[0026] The woven net includes circular loop ropes 4. Inside the loop ropes 4, several horizontal ropes 6 and vertical ropes 9 are connected by knots. The horizontal ropes 6 and vertical ropes 9 are perpendicular to each other to form a square hollow. The diameter of the loop ropes 4 and the density of the horizontal ropes 6 and vertical ropes 9 can be adjusted according to the actual situation to adapt to different working conditions.

[0027] A buckle 8 is installed at the junction of the horizontal rope 6 and the vertical rope 9. The buckle 8 has a cross-shaped structure and connects the horizontal rope 6 and the vertical rope 9. The buckle 8 is made of metal to ensure strength. The buckle 8 is placed at the junction of the horizontal rope 6 and the vertical rope 9 in a cross manner. Then, the four legs of the buckle 8 are pressed in opposite directions to fix the shape. The horizontal rope 6 and the vertical rope 9 are tied together by the properties of the metal material. Compared with the traditional knotting method, there will be no protrusions formed by knotting, which will not hurt pedestrians who accidentally fall into the well.

[0028] This application also uses a knotted connection method, but it is limited to the connection between the loop rope 4 and the vertical rope 9, the horizontal rope 6, and the connecting rope 3. These connection points are all at the edge, so they will not hurt pedestrians who accidentally fall into the well, and at the same time, they can save costs.

[0029] Twelve connecting ropes 3 are fixedly installed at the outer edge of the woven net. Both ends of the connecting ropes 3 are connected to the loop ropes 4 by knotting. Adjacent connecting ropes 3 are evenly arranged at the same angle on the outer edge of the loop ropes 4 to ensure stable and concentrated force. Each connecting rope 3 is detachably connected to a lifting lug 7. One end of the lifting lug 7 is fixedly embedded in the well wall 1, and the other end of the lifting lug 7 is a circular structure with a notch at the upper part of the side facing the well wall 1. The connecting rope 3 is hooked into the lifting lug 7 to complete the connection. Through force analysis, it can be seen that the tension applied by the connecting rope 3 to the lifting lug 7 is in the opposite direction to the notch, ensuring that the connecting rope 3 will not fall off accidentally.

[0030] It should be noted that the loop rope 4, vertical rope 9, horizontal rope 6 and connecting rope 3 are all internally embedded with fine steel wire rope 5 to ensure the overall structural strength and corrosion resistance, and the connecting rope 3 will not become a weak point.

[0031] A pad ring 10 is fixedly installed on the inner side of the well wall 1. The pad ring 10 is located above the lifting lug 7. A retaining edge 2 is placed on the upper part of the pad ring 10. The retaining edge 2 is made of soft rubber material. The width of the retaining edge 2 is greater than the length of the lifting lug 7. An extension edge 21 is also inclinedly installed on the lower part of the retaining edge 2. The extension edge 21 covers the upper part of the lifting lug 7. When a pedestrian accidentally falls into the well, his outstretched limbs, including his head, will not accidentally hit the lifting lug 7. Instead, they will be protected by the retaining edge 2 and the extension edge 21. Even if he hits the lifting lug 7, the retaining edge 2 and the extension edge 21 will extend downwards while being subjected to force, protecting the safety of the pedestrian who accidentally falls into the well.

[0032] The upper part of the retaining edge 2, near the well wall 1, is also provided with a beveled edge that gradually narrows upwards and fits tightly against the well wall 1. On the one hand, this can improve the strength of the retaining edge 2, making it less prone to deformation and detachment. On the other hand, when rainwater seeps down from the gap between the well cover 11 and the well wall 1, the rainwater will not accumulate on one side, but will flow down quickly along the angle of inclination. Water will not accumulate at the retaining edge 2, reducing the corrosion of the woven mesh caused by water accumulation at this location.

[0033] It should be noted that the terms "first, second, and third" used in this utility model are for descriptive purposes only and do not indicate any order. They should not be construed as indicating or implying relative importance, and can be interpreted as names.

[0034] Those skilled in the art should understand that the embodiments of the present invention described above and shown in the accompanying drawings are merely examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functional and structural principles of the present invention have been shown and explained in the embodiments. Without departing from the principles, the implementation of the present invention may have any modifications or variations.
