TECHNICAL FIELD

[0001] The utility model relates to the technical field of inspection well, concretely is a plastic inspection well with built-in deformable pressure bearing structure. BACKGROUND

[0002] In the huge framework of modern municipal drainage system, the plastic inspection well has become an indispensable key component with its corrosion resistance, light weight, convenient installation and many other advantages. However, further investigation into its actual application status will find that the inherent defects in the design and structure of the traditional plastic inspection well continue to constrain the efficient operation of the drainage system and related maintenance work.

[0003] From the perspective of personnel convenience, the peripheral support structure of the traditional plastic inspection well is single in form and lacks flexibility. In the maintenance work of urban drainage pipelines, personnel need to frequently enter and exit the inspection well for pipeline dredging, equipment maintenance and other operations. However, the existing support structure often leads to cramped space at the wellhead, hindering the movement of personnel during climbing and requiring them to be extremely careful, greatly reducing the efficiency of entry and exit. In some emergency rescue operation scenarios, such as the need to quickly dredge a blocked drainage pipeline after heavy rain, the additional time spent may lead to an increase in the scope of urban waterlogging and the depth of accumulated water, posing a serious threat to the safety of life and property of surrounding residents.

DETAILED DESCRIPTION

[0031] The technical solutions in the embodiments of the utility model will be clearly and completely described in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0032] Please see Figures 1-7 This utility model provides a technical solution: a plastic inspection well with a built-in deformable pressure-bearing structure.

[0033] Example 1

[0034] This embodiment discloses: a well shaft 1, a functional ladder 2 fixedly installed on the inner surface of the upper end of the well shaft 1, and a well seat 3 fixedly installed at the upper end of the well shaft 1. The surface of the well seat 3 is provided with a deformation bearing mechanism, which facilitates personnel entry and exit while ensuring stable support for the well cover through deformation and storage.

[0035] The deformation pressure bearing mechanism includes: an installation cavity 4, which is opened on the inner surface of the well base 3, and a sliding rod 5 is fixedly installed inside the installation cavity 4. A sliding pressure bearing seat 6 is installed on the outer surface of the sliding rod 5. A rotating drive gear 7 is installed on the inner surface of the installation cavity 4, and a displacement rod 8 is fixedly connected to one end of the shaft of the drive gear 7. A rotating gear ring 9 is installed inside the upper surface of the well base 3, and a handle 10 is fixedly installed on the upper surface of the gear ring 9. A rotating pressure bearing rod 11 is installed on the outer surface of the upper end of the pressure bearing seat 6.

[0036] The displacement rod 8 is concentrically arranged with the drive gear 7, and the displacement rod 8 is threadedly connected to the pressure seat 6;

[0037] The lower surface of the toothed ring 9 is uniformly provided with tooth blocks, and the toothed ring 9 is meshed with the drive gear 7 through the tooth blocks;

[0038] A spring is connected between the pressure rod 11 and the pressure seat 6, and the outer surface of the pressure rod 11 is flush with the outer surface of the pressure seat 6.

[0039] When staff need to enter shaft 1 via functional ladder 2, such as Figure 7 As shown, first grasp the handle 10 at the upper end of the well base 3 and rotate it. Since the handle 10 is fixedly installed on the upper surface of the toothed ring 9, and the tooth blocks evenly arranged on the lower surface of the toothed ring 9 mesh with the drive gear 7, rotating the handle 10 will drive the toothed ring 9 to rotate, which in turn drives the drive gear 7 to rotate. One end of the shaft of the drive gear 7 is fixedly connected to the displacement rod 8, and the displacement rod 8 is threadedly connected to the pressure seat 6. When the drive gear 7 rotates, the displacement rod 8 rotates accordingly. Under the action of the thread, the pressure seat 6 is pushed to slide along the sliding rod 5 in the installation cavity 4. As the pressure seat 6 slides, the rotating pressure rod 11 installed on the outer surface of its upper end rotates, deforms, and is stored. At this time, there is no obstruction at the well opening, which makes room for workers to enter and exit the inspection well, greatly improving the efficiency of entry and exit.

[0040] When the well lid is subjected to external pressure such as vehicle rolling, pedestrian stepping, etc., the pressure is transmitted to the pressure bearing rod 11 and the pressure bearing seat 6, and the pressure bearing rod 11 and the pressure bearing seat 6 can stably bear the pressure, and the design that the pressure bearing rod 11 is flush with the outer surface of the pressure bearing seat 6 ensures that the pressure bearing rod 11 can be pressed into the pressure bearing seat 6 when the pressure bearing seat 6 is received into the installation cavity 4, and can be timely unfolded and supported when there is pressure, thereby ensuring the stable support of the well lid, preventing the well lid from sinking and shaking, and reducing the safety hazard.

[0041] Embodiment two

[0042] This embodiment discloses that the inside of the installation cavity 4 is provided with a supporting mechanism, which further ensures the support effect on the well lid by supporting the bottom of the deformed pressure bearing mechanism.

[0043] The supporting mechanism comprises a supporting block 12 fixedly arranged on the lower surface of the pressure bearing seat 6, and the lower surface of the pressure bearing seat 6 is fixedly provided with a toothed rod 13, one end of the inside bottom surface of the installation cavity 4 is provided with a rotating angle gear 14, and one end of the rotating shaft of the angle gear 14 is fixedly connected with a lower supporting rod 15.

[0044] The lower end surface of the supporting block 12 is flush with the upper end surface of the lower supporting rod 15, and the lower surface of the toothed rod 13 is flush with the lower surface of the supporting block 12.

[0045] The side surface of the toothed rod 13 towards the angle gear 14 is uniformly provided with a tooth block, and the toothed rod 13 is meshingly connected with the angle gear 14 through the tooth block.

[0046] When the pressure bearing seat 6 is driven to slide outwards to support, at this time, the pressure bearing seat 6 drives the angle gear 14 and the lower supporting rod 15 to rotate through the meshing of the toothed rod 13 and the angle gear 14, until the pressure bearing seat 6 is moved in place, at this time, one end of the lower supporting rod 15 is just rotated to the lower end of the supporting block 12 to assist the pressure bearing seat 6 to better support the well lid.

[0047] Although the embodiments of the utility model have been shown and described, it can be understood by those skilled in the art that various changes, modifications, replacements and variations can be made to these embodiments without departing from the principles and spirits of the utility model, and the scope of the utility model is defined by the appended claims and their equivalents.
