[0002] The urban drainage system is an important municipal infrastructure in the city. It plays an important role in the lives of residents and the safety of the water system. In recent years, extreme rainstorms have occurred frequently, and the regulations have increased the value of the rainwater recurrence period. The existing rainwater pipe network does not meet the design flow requirements under the new standards. It is necessary to renovate and expand the rainwater pipe network. At this time, there are the following problems:

[0003] 1. If excavation is to be carried out to construct rainwater pipes, the road surface needs to be excavated, which will affect traffic. At the same time, relevant municipal pipelines such as water supply, electricity, and gas need to be relocated or protected, which is very difficult.

[0004] 2. If the rainwater pipe is constructed by pipe jacking, it is necessary to connect it with the downstream main pipe at an elevation so that the rainwater pipe meets the minimum soil cover depth requirement, which is often difficult to meet.

[0005] 3. Regardless of excavation construction or pipe jacking construction, the construction period is long and the investment is large. Utility Model Content

[0029] The present invention will be further described in detail below in conjunction with the accompanying drawings so that those skilled in the art can implement the invention with reference to the description.

[0030] It should be noted that, in the description of the present invention, the terms "lateral", "longitudinal", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description.

[0031] Figure 1-Figure 2 A rainwater pipe inspection well structure provided by the embodiment of the utility model includes:

[0032] Inspection well body 1;

[0033] A limiting mechanism, which is arranged on the inner wall of the inspection well body 1;

[0034] A mounting bracket, which is slidably arranged on the limiting mechanism, and under the action of external force, the mounting bracket can move upward to be separated from the limiting mechanism;

[0035] The flow promoter 2 is arranged on the mounting bracket.

[0036] In this embodiment, the inspection well body 1 can adopt the existing inspection well, and there is no need to re-construct. It only needs to set the limit mechanism on the inner wall of the inspection well body 1, and then install the mounting bracket on the limit mechanism, and install the flow pusher 2 on the mounting bracket, so that the flow pusher 2 is fixed to the lower part of the inspection well, and the flow pusher 2 can generate a strong water flow with low tangential flow, increase the water flow speed in the rainwater pipe, and thus improve the drainage capacity of the pipe. When the staff goes down the well for inspection, due to the presence of the flow pusher 2, it will cause inconvenience for the staff to go down the well, so in this embodiment, the mounting bracket can be moved upward under the action of external force to separate from the limit mechanism, so before the staff goes down the well, the mounting bracket can be lifted, so that the mounting bracket is separated from the limit mechanism when it moves to the wellhead, so that the staff can go down the well smoothly. After the inspection is completed, the mounting bracket is installed on the limit mechanism by sliding up and down, and the mounting bracket is slowly lowered to the lowest position, and the flow pusher 2 can be moved to the lower part of the inspection well. When lifting the flow pusher 2, the staff can set an electric lifting device at the wellhead and lift the flow pusher 2 through the lifting device. Since the flow pusher 2 has a compact structure and light weight, the staff can also set a manual lifting frame at the wellhead and manually lift the mounting bracket and the flow pusher 2 thereon. In this embodiment, since the flow pusher 2 needs to be moved, the wires connected thereto should be reserved with sufficient length to ensure its movement.

[0037] Preferably, as another embodiment of the utility model, the mounting bracket includes:

[0038] A horizontal plate 3, the flow promoter 2 is arranged on the upper end of the horizontal plate 3;

[0039] The connecting plate 4 is slidably arranged on the limiting mechanism and connected to the horizontal plate 3. Under the action of external force, the connecting plate 4 can move upward to be separated from the limiting mechanism.

[0040] In this embodiment, the flow promoter 2 is fixed to the upper end of the horizontal plate 3, and its blades extend out of the horizontal plate 3 and are connected to the limit mechanism by sliding up and down through the connecting plate 4. Specifically, as one of the specific implementations, the limit mechanism includes:

[0041] Two rails 5 are vertically arranged on the inner wall of the inspection well body 1, the upper ends of the rails 5 extend upward to the opening of the inspection well body 1, and limit blocks 6 are provided at both upper and lower ends thereof, and the upper ends of the rails 5 are provided with first pin holes 7;

[0042] Two sliding members 8 are vertically provided with through slots corresponding to the track 5, and are slidably arranged on the track 5 through the through slots. The two sliding members 8 are connected by a connecting rod so that they can be lifted and lowered synchronously. A lifting ring 9 is provided at the middle of the upper end of the connecting rod. The sliding members 8 are each provided with a second latch hole 10. When the sliding members 8 slide upward, the second latch hole 10 can be connected with the corresponding first latch hole 7 to form a latch channel;

[0043] Two latches, which are detachably mounted in the two latch channels;

[0044] The two positioning members 11 are arranged opposite to each other and are respectively connected to the two sliding members 8. The ends of the two positioning members 11 that are close to each other are vertically provided with limiting grooves, and the upper ends of the limiting grooves are open. The two ends of the connecting plate 4 can be slid up and down in the two limiting grooves.

[0045] In the above scheme, the sliding member 8 is arranged on the two rails 5 so as to slide up and down. When the sliding member 8 moves downward to contact with the lower limit block 6, it rests on the limit block 6, and the connecting plate 4 can be fixed at this time. When the sliding member 8 moves upward to near the wellhead of the inspection well and contacts with the upper limit block 6, the second latch hole 10 on the sliding member 8 overlaps with the first latch hole 7 on the rail 5, and the two form a latch channel. At this time, the sliding member 8 can be fixed on the rail 5 by inserting the latch into the latch channel, which is convenient for removing the connecting plate 4 from the limit groove and inserting the two ends of the limit plate into the limit groove. The latch is not drawn in the attached figure.

[0046] When the flow pusher 2 is to be lifted, the hook is first dropped into the inspection well and connected to the lifting ring 9, and then the lifting is started, driving the two sliders to move upward, thereby driving the mounting bracket to move upward. When the sliding member 8 moves upward to conflict with the upper limit block 6, the latch is installed in the latch channel, the sliding member 8 is fixed, and then the staff moves the flow pusher 2 upward to remove it from the two positioning members 11, so that the staff can smoothly enter the inspection well. After the staff completes the inspection, the connecting plate 4 is kept vertical, and its two ends are extended downward into the limiting grooves on the two positioning members 11 until the connecting plate 4 conflicts with the bottom of the limiting groove, and the connecting plate 4 is fixed on the two positioning members 11 under the action of gravity. Then the two latches are removed, and the lifting ring 9 is slowly lowered until the sliding member 8 moves downward to conflict with the lower limit block 6, and is placed on the limit block 6, at which time the connecting plate 4 can be fixed.

[0047] Preferably, as another embodiment of the utility model, at least two connecting rods are provided and are spaced apart from each other.

[0048] In this embodiment, the number of connecting rods is greater, so that the connection between the two sliding members 8 is more stable. At this time, the lifting ring 9 is arranged in the middle of the upper end of the uppermost connecting rod.

[0049] Preferably, as another embodiment of the present utility model, a plurality of through holes are evenly distributed on the connecting plate 4 .

[0050] In this embodiment, a plurality of through holes are evenly distributed on the connecting plate 4, so that water can pass through the connecting plate 4, thereby reducing the obstruction to the water flow.

[0051] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation scheme. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the embodiments shown and described herein.
