Description

Technical Field

[0001] This utility model relates to the field of urban underground infrastructure technology, specifically to a fall prevention device for inspection wells. Background Technology

[0002] Inspection wells are installed to facilitate the maintenance and installation of underground infrastructure such as power supply, water supply, drainage, sewage, communications, cable TV, gas pipes, and street light lines in cities. They are generally located at pipe intersections, bends, changes in pipe diameter or slope, and at regular intervals on straight pipe sections to facilitate the periodic inspection of ancillary structures.

[0003] Manhole covers are typically used to prevent pedestrians from accidentally falling into them. However, manhole covers may lose their protective function due to missing, damaged, or moved covers. Current technology usually involves adding a fall protection net at the manhole opening to further prevent people from falling in. However, existing fall protection nets lack specialized adjustment devices and cannot be directly adapted to various manhole sizes. Therefore, construction workers usually need to accurately measure the manhole opening before installing the fall protection net, a process that is tedious and time-consuming.

[0004] Therefore, a fall prevention device for inspection wells needs to be proposed to solve this problem. Utility Model Content

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. In the description of the present utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0020] A fall arrestor for inspection wells, such as Figures 1-4 As shown, it includes a well body 1 and a well cover 2. A frame 3 is provided on the end face of the well body 1 near the well cover 2, and it can be adjusted according to the size of the well body 1. A connecting component is provided between the frame 3 and the well body 1. A stainless steel mesh 5 is laid in the frame 3.

[0021] Practical benefits: The adjustable frame 3 allows the fall arrestor to adapt to different well opening shapes, improving its applicability.

[0022] like Figures 1-4 As shown, specifically, the frame 3 includes several fixing parts 31 and an adjusting rod. The fixing parts 31 are evenly arranged around the well body 1, and the two ends of the adjusting rod are rotatably mounted on adjacent fixing parts 31.

[0023] The adjusting rod is composed of several angle irons 32 and positioning pins 33. Several through holes 321 are evenly opened on the angle irons 32. The positioning pins 33 are used to fix and limit the angle irons 32 by passing through the mutually cooperating through holes 321. Adjacent angle irons 32 are provided with locking parts that can be connected to the side wall of the well body 1.

[0024] The overall structure of the frame 3 is determined by several fasteners 31. The fasteners 31 are connected by angle irons 32 and positioning pins 33 to form the overall frame 3, thus ensuring the stability and safety of the frame 3.

[0025] like Figures 1-4 As shown, the well body 1 has a groove 11 on its side wall. The locking component includes a connecting rod 4. Both ends of the connecting rod 4 are provided with hooks 41. One hook 41 is used to hook the angle iron 32, and the other hook 41 is used to hook the groove 11. The rotation of the angle iron 32 is restricted by the hooks 41, which further improves the stability and safety of the frame 3.

[0026] like Figures 1-4 As shown, a protrusion 322 is provided between adjacent through holes 321 on the angle iron 32. The stainless steel mesh 5 is fixed by being wound around the protrusion 322. The stainless steel wire has the characteristics of corrosion resistance and wear resistance. The stainless steel mesh 5 ensures the stability and strength of the fall protection device. Different mesh sizes can be wound according to needs to achieve a good fall protection effect without affecting the ventilation performance inside the well. The protrusion 322 can hold the stainless steel mesh 5 in place to ensure that it will not fall off or shift.

[0027] like Figures 1-4As shown, the well body 1 has several bolt holes 12 on its side wall, and the fastener 31 has connecting ears 311 on both sides that mate with the bolt holes 12. The connecting assembly includes several expansion bolts 6 and matching nuts 7. The expansion bolts 6 pass through the connecting ears 311 and the bolt holes 12 respectively, and the frame 3 is fixed to the well body 1 by tightening the nuts 7.

[0028] Installation process: The worker first uses expansion bolts 6 and nuts 7 to fix the fixing part 31 to the well body 1, then adjusts the angle iron 32. After the angle iron 32 is adjusted, the positioning pin 33 and connecting rod 4 are used to limit the angle iron 32. Finally, the stainless steel wire is wound around the protrusion 322 on the angle iron 32 as required, thus completing the installation of the fall protection device.

[0029] Furthermore, the end face of frame 3 near the wellhead is coated with a layer of reflective warning paint, which allows the paint to reflect light at night or in low light conditions, alerting passersby and further reducing the occurrence of fall accidents.

[0030] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0031] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
