Description

Technical Field

[0001] This utility model relates to the field of inspection well technology, and more specifically, to a prefabricated rainwater inspection well. Background Technology

[0002] In the existing technology, the existing prefabricated rainwater inspection wells have many inconveniences in the production and manufacturing process. The traditional prefabrication process usually uses fixed molds to cast the product in one go. Although this method can ensure the structural strength of the product, the operation is complicated in the process of mold disassembly, demolding and subsequent maintenance.

[0003] The existing rotating covers on top of manholes present significant operational obstacles during opening. Traditional manhole covers are usually made of heavy cast iron or concrete, which is quite heavy. Operators need to use special tools to open them, which is time-consuming, laborious, and poses safety hazards. More importantly, the opening mechanism of existing manhole covers is not user-friendly and lacks an effective manual operating device.

[0004] Traditional manhole designs are usually based on standard drawings or conventional specifications. Designers often only consider the most common pipe diameter connection requirements during the product development stage. This "one-size-fits-all" design approach ignores the diversity and complexity of pipe specifications in actual engineering, resulting in a large gap between the product and actual needs.

[0007] The present invention is further configured such that a control block is installed on the adjusting cylinder, the control block being adapted to the sealing groove, thereby facilitating the completion of the fitting process of the adjusting cylinder by using the control block.

[0008] The present invention is further configured such that a guide sleeve is rotatably connected to the hinge seat, and a guide rod is slidably connected to the guide sleeve. The cooperation of the various components facilitates the completion of the sliding movement process of the guide rod.

[0009] The present invention is further configured such that a mounting seat is installed on the rotating cover, the mounting seat is rotatably connected to the guide rod, and a pull rod is installed on the rotating cover. The cooperation of the various components facilitates the completion of the pulling process of the pull rod.

[0010] The present invention is further provided that a pull ring is connected to the pull rod, so as to facilitate the opening process of the rotating cover.

[0011] The present invention is further configured such that a connecting component is provided on the precast cement well, the connecting component including a first connecting seat and a second connecting seat, the first connecting seat and the second connecting seat being disposed on the precast cement well, and a third connecting seat being installed on the precast cement well, thereby facilitating the completion of the connection process for external pipelines through the cooperative use of each component.

[0012] The present invention is further configured such that a control seat is installed on the first connecting seat, the second connecting seat and the third connecting seat, thereby facilitating the completion of the pipe fixing process by using the control seat.

[0013] The present invention is further configured such that the control seat is threadedly connected with bolts, thereby facilitating the fixing process of the precast concrete well and the external pipeline.

[0014] (III) Beneficial Effects Compared with the prior art, this utility model provides a prefabricated rainwater inspection well, which has the following beneficial effects: 1. The prefabricated components achieve modular assembly of the inspection well through the fitting configuration of the cover plate and the regulating cylinder. The control groove on the cover plate and the connecting block on the cement prefabricated well form a precise fit, ensuring stable connection and accurate positioning between components. The matching design of the control block on the regulating cylinder and the sealing groove of the cover plate enables rapid fitting. This modular design significantly simplifies the prefabrication process and reduces the complexity of on-site construction.

[0015] 2. The opening assembly, through the ingenious cooperation of the top frame, rotating cover, hinge seat, guide sleeve and guide rod, completely solves the problem of difficult opening of traditional manhole covers. The design of the pull rod and pull ring provides operators with a convenient operating interface, and the manhole cover can be easily opened without the aid of special tools. The sliding connection mechanism of the guide sleeve and guide rod ensures the smooth movement of the rotating cover during the opening process and avoids jamming.

[0016] 3. The connection assembly achieves flexible adaptation to pipes of different specifications through the multi-point connection design of the first connecting seat, the second connecting seat and the third connecting seat. The threaded connection of the control seat and the bolt provides adjustable connection strength, which can adapt to external pipes of different materials and specifications. The setting of multiple connecting seats allows a single inspection well to connect multiple pipes of different directions and specifications at the same time. Attached Figure Description
