Abstract
Description
Technical Field
[0001] The utility model provides a sewage well anti-falling structure, belonging to the technical field of sewage wells. Background Art
[0002] A sewage well is a facility used to collect and treat urban sewage. Its main function is to collect sewage generated in residential, commercial and industrial areas, and transport the sewage to sewage treatment plants for treatment to protect the environment and human health. A sewage well is mainly composed of two parts: a well shaft and a well cover. The well shaft is an upright tubular structure, generally composed of cement masonry or precast concrete. The inner wall needs to be smooth to allow sewage to flow smoothly. The well cover is installed on the top of the well shaft to close the wellhead. It is usually made of cast iron or steel plate materials and has a high weighing capacity. Sewage wells are an indispensable part of urban drainage systems and must be maintained and managed regularly.
[0003] When the manhole cover is missing or severely damaged due to theft, aging, accidental impact, etc. and cannot effectively cover the wellhead, or in extreme weather such as floods and typhoons, the manhole cover may be washed away by the water flow or displaced by floating objects, which may cause people or animals to fall into the well. Current sewage wells usually only have a ladder on the well shaft and there is no anti-fall design. In addition, there is water in the sewage pipe connected to the lower end of the well shaft all year round. If a person is knocked unconscious when falling, he or she may drown, causing immeasurable accidents. Utility Model Content
[0004] The technical problem to be solved by the utility model is that the current sewage well has no anti-fall design.
[0005] In order to solve the above problems, the utility model proposes a technical solution: a sewage well anti-fall structure, comprising a sewage pipe, a well shaft, and a ladder arranged in the well shaft and the sewage pipe; a plurality of stainless steel protective nets of different heights are equidistantly arranged in the well shaft, and the stainless steel protective nets are fixed by hooks arranged at equal angles on the inner wall of the well shaft, and a through hole for personnel to pass through is arranged at one end of the stainless steel protective net, and any two adjacent through holes are staggered;
[0006] As an improvement, the ladder includes a round ladder and a square ladder. The round ladder is arranged above the top stainless steel protection net and in the middle of any two adjacent stainless steel protection nets, and the square ladder is arranged at the passage of the stainless steel protection net and below the bottom stainless steel protection net.
[0007] As an improvement, a support rod is provided below the square ladder at the bottom of the sewage pipe in the wellbore, and the square ladder in the sewage pipe is installed through the support rod;
[0008] As an improvement, the stainless steel protective net includes a plurality of cables intersecting horizontally and vertically, and the outer ends of the plurality of cables are connected to the annular steel cable;
[0009] As an improvement, the hook opens upwards.
[0010] Beneficial effects of the utility model:
[0011] A stainless steel protective net fixed with hooks is arranged in the wellbore through the opening, so that when a person falls accidentally, he can fall on the stainless steel protective net, thus avoiding falling directly into the sewage pipe. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The utility model is further described below in conjunction with the accompanying drawings.
[0018] according to Figure 1 —4: The utility model provides a sewage well anti-fall structure: comprising a sewage pipe 1, a well shaft 2, and a ladder 3 arranged in the well shaft 2 and the sewage pipe 1; a plurality of stainless steel protective nets 4 of different heights are equidistantly arranged in the well shaft 2, and the stainless steel protective nets 4 are fixed by hooks 5 arranged at equal angles on the inner wall of the well shaft 2; one end of the stainless steel protective net 4 is provided with a through hole 6 for personnel to pass through, and any two adjacent through holes 6 are staggered, and the stainless steel protective net 4 comprises a plurality of cables 10 intersecting horizontally and vertically, and the outer ends of the plurality of cables 10 are connected to an annular steel cable 11; by staggering the through holes 6 in the well shaft 2 and fixing the stainless steel protective nets 4 with hooks 5, when a person accidentally falls, he can fall on the stainless steel protective net 4, thereby avoiding falling directly into the sewage pipe;
[0019] according to Figure 3As shown: As an improvement, the ladder 3 includes a round ladder 7 and a square ladder 8. The round ladder 7 is arranged above the top stainless steel protection net 4 and in the middle of any two adjacent stainless steel protection nets 4, and the square ladder 8 is arranged at the through-port 6 of the stainless steel protection net 4 and below the bottom stainless steel protection net 4; a support rod 9 is arranged below the square ladder 8 at the bottom of the sewage pipe 1 in the shaft 2, and the square ladder 8 in the sewage pipe 1 is installed through the support rod 9; by arranging the round ladder 7, personnel can move through the through-port 6 during maintenance, and the square ladder 8 enables personnel to climb when passing through the through-port 6 and in the sewage pipe 1;
[0020] according to Figure 4 As shown: As an improvement, the opening of the hook 5 is facing upward; in this way, when a person falls on the stainless steel protective net 4, the stainless steel protective net 4 will not fall off.
[0021] The principle of the utility model is as follows: when the manhole cover is detached from the shaft 2, if a person accidentally falls into the shaft 2, he will fall on the stainless steel protective net 4. The person who has fallen can climb up again by climbing the circular ladder 7. The staggered through-holes 6 prevent the person who has fallen from falling directly into the sewage pipe 1, thereby increasing safety. When maintenance is required, the staff first climbs the circular ladder 7 and then climbs the square ladder 8 in the through-hole 6 to reach the middle of the two stainless steel protective nets 4. When reaching the middle of the two stainless steel protective nets 4, move through the circular ladder 7 until reaching the through-hole 6 below, and pass through the shaft 2 in the same way. When reaching the sewage pipe 1, climb the square ladder 8 on the support rod 9 to reach the sewage pipe 1. In this way, the sewage well can be smoothly maintained, and when the maintenance is completed, you can go up in the same way.
[0022] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
