Description

Technical Field

[0001] The utility model relates to the field of aqueduct maintenance, and particularly to a maintenance device for a U-shaped aqueduct. Background Technique

[0002] In modern water conservancy construction, as a key water conveyance structure, the U-shaped aqueduct is usually designed to adapt to complex terrain environments, requiring a strong and durable structure. However, with the increase in the size of the aqueduct, the height of the aqueduct body generally reaches 20 to 33 meters, and the single-span length can reach 20 to 30 meters, facing a series of challenges during its construction and maintenance processes.

[0003] Specifically, the generally selectable maintenance scheme in the prior art is to cover a protective film on the outside of the U-shaped aqueduct. The height difference between the top of the aqueduct body and the ground makes the air volume at the top of the aqueduct body larger, resulting in instability of the temporary support for the construction of covering the protective film and triggering safety risks; even if the operation of manually covering the protective film is carried out under windless conditions, due to the high height, the laying efficiency of the protective film will be affected. Therefore, the maintenance method of setting a protective film to reduce water evaporation is no longer applicable. In addition, the tall aqueduct body makes the internal and external maintenance operations complicated, and the traditional manual spraying maintenance method is difficult to ensure uniformity, resulting in limited maintenance effects.

[0004] For this reason, a maintenance device for a U-shaped aqueduct is proposed to solve the above technical problems. Content of the Utility Model

[0005] The technical problem solved by the utility model is that for aqueducts with larger sizes, the existing method of covering a protective film to reduce water evaporation is not applicable, and at the same time, it is difficult to ensure the uniformity of manual spraying during the maintenance of the tall aqueduct body, resulting in limited maintenance effects.

[0006] To solve the above technical problems, the technical solutions adopted by the utility model are as follows:

[0008] A moving track, which is arranged on the capping of the U-shaped aqueduct and is laid along the traveling direction of the U-shaped aqueduct;

[0009] An installation plate, with moving wheels sliding in the moving track below and a water storage tank above;

[0010] Two booster pumps are respectively arranged on the left and right sides of the mounting plate. The water inlets are respectively connected to the water storage tank through connecting pipes, and each water outlet is provided with a main water pipe; each main water pipe is connected with two branch pipes, and the two branch pipes are respectively located inside and outside the U-shaped aqueduct and are close to the U-shaped aqueduct; the two branch pipes of the left booster pump respectively fit the inner and outer contours of the left half of the U-shaped aqueduct, and the two branch pipes of the right booster pump respectively fit the inner and outer contours of the right half of the U-shaped aqueduct.

[0011] A number of spray holes are evenly arranged on the branch pipes and face the U-shaped aqueduct.

[0012] Particularly, it further includes a horizontal driving motor, which is arranged on the mounting bracket of the moving wheel, and the output shaft is fixedly connected to the rotating shaft of the moving wheel.

[0013] Particularly, the number of the booster pumps is four, which are arranged on the mounting plate in a square distribution.

[0014] Particularly, it further includes a horizontal connecting rod perpendicular to the traveling direction of the U-shaped aqueduct, and both ends of the horizontal connecting rod are respectively connected to the two branch pipes located inside the U-shaped aqueduct.

[0015] Particularly, a protective cylinder is provided on the lower surface of the mounting plate, and the protective cylinder is sleeved on the outer side of the top of the branch pipe.

[0016] Compared with the prior art, the present utility model has the following advantages and beneficial effects: by setting a moving track on the U-shaped aqueduct cap of the present utility model to drive the upper mounting plate and the water storage tank on the mounting plate to move together, and using the booster pump in cooperation with the branch pipes that fit the inner and outer wall contours of the U-shaped aqueduct, the comprehensive spraying of the U-shaped aqueduct is realized, effectively improving the uniformity of spraying maintenance, ensuring the maintenance effect of the U-shaped aqueduct, and also effectively avoiding the unstable problems caused by the large height difference and large air volume of the temporary supports erected in the prior art, reducing potential safety hazards.

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model, so as to have a further understanding of the concept of the present utility model, the technical problems to be solved, the technical features constituting the technical solutions, and the technical effects brought about.

[0021] As Figures 1 to 2 shown, a U-shaped aqueduct maintenance device includes:

[0022] A moving track 1 is arranged on the trough cap 2 of the U-shaped aqueduct 3 and is laid along the traveling direction of the U-shaped aqueduct 3;

[0023] An installation plate 4 is provided with moving wheels 6 sliding in the moving track 1 below and a water storage tank 7 above;

[0024] Two booster pumps 5 are respectively arranged on the left and right sides of the installation plate 4. The water inlets are respectively connected to the water storage tank 7 through connecting pipes, and each water outlet is provided with a main water pipe 8; each main water pipe is connected with two branch pipes 9. The two branch pipes 9 are respectively located inside and outside the U-shaped aqueduct 3 and are close to the U-shaped aqueduct 3; the two branch pipes 9 of the left booster pump 5 respectively fit the inner and outer contour of the left half of the trough body of the U-shaped aqueduct 3, and the two branch pipes 9 of the right booster pump 5 respectively fit the inner and outer contour of the right half of the trough body of the U-shaped aqueduct 3;

[0025] A number of spray holes are evenly distributed on the branch pipes 9 and face the U-shaped aqueduct 3.

[0026] The working principle of the present utility model is as follows: The present utility model lays a moving track 1 on the trough cap 2 of the U-shaped aqueduct 3 and sets moving wheels 6 below the installation plate 4, so that the installation plate 4 can move along the traveling direction of the U-shaped aqueduct 3 on the trough cap 2 of the U-shaped aqueduct 3. After the booster pump 5 pumps out the water in the water storage tank 7, it is discharged into the branch pipes 9 from the water outlet, and the spray holes on the branch pipes 9 spray towards the trough body of the U-shaped aqueduct 3 to complete the maintenance of the U-shaped aqueduct. Since the branch pipes 9 fit the inner and outer wall contours of the U-shaped aqueduct 3, and the spray holes are evenly distributed on the branch pipes 9, the uniformity of the overall maintenance of the U-shaped aqueduct 3 can be effectively ensured. By cooperating with the aforementioned moving wheels 6 and moving track 1, the maintenance area of the trough body of the U-shaped aqueduct 3 can be comprehensively covered.

[0027] As a preferred embodiment, it further includes a horizontal driving motor 10. The horizontal driving motor 10 is arranged on the mounting bracket of the moving wheel 6, and the output shaft is fixedly connected to the rotating shaft of the moving wheel 6.

[0028] In this embodiment, a method for driving the moving of the mounting plate 4 is provided. Specifically, by installing a horizontal driving motor 10 on the mounting frame of the moving wheel 6, the horizontal driving motor 10 is utilized to drive the moving wheel 6 to move within the moving track 1, thereby realizing the moving process of the device of the present utility model. Besides this embodiment, it is also possible to set up a winch at the end of the U-shaped aqueduct 3 after setting up the moving track 1, vertically arranged plates are segmented on the U-shaped aqueduct 3, and a hydraulic cylinder is arranged between the vertically arranged plate and the mounting plate, etc. to realize the moving of the mounting plate 4.

[0029] As a preferred embodiment, the number of the booster pumps 5 is four, which are arranged on the mounting plate 4 in a square distribution.

[0030] In this embodiment, a specific layout method of the booster pump 5 is provided. The number of the booster pumps 5 is four, which are arranged on the mounting plate 4 in a square distribution, such that there are two booster pumps 5 on each of the left and right trough bodies of the U-shaped aqueduct 3. The booster pumps 5 on the same side are arranged along the traveling direction of the U-shaped aqueduct 3 to cover the front end and the rear end of the U-shaped aqueduct 3. When the mounting plate 4 moves, the two booster pumps 5 at the front end and the rear end respectively spray water onto the trough body of the U-shaped aqueduct 3 through the main water pipe 8 and the branch pipe 9, thereby avoiding the positions missed during the spraying and curing process by a single booster pump 5 and its supporting structures. In addition, the layout mode of the booster pumps 5 can also be changed to an alternate arrangement on the left and right sides to avoid the branch pipes 9 located inside the U-shaped aqueduct 3 from conflicting with each other, and it can also ensure that the overall range of the trough body of the U-shaped aqueduct 3 is evenly covered by the branch pipes 9.

[0031] As a further embodiment, it further includes a horizontal connecting rod 11 perpendicular to the traveling direction of the U-shaped aqueduct 3, and both ends of the horizontal connecting rod 11 are respectively connected to two branch pipes 9 located inside the U-shaped aqueduct 3.

[0032] In this embodiment, by arranging the horizontal connecting rod 11 between the two branch pipes 9 located inside the U-shaped aqueduct 3, the position of the branch pipes 9 is strengthened, avoiding the branch pipes 9 from being deflected due to external forces and affecting the spraying and curing effect.

[0033] As a preferred embodiment, a protective cylinder 12 is provided on the lower surface of the mounting plate 4, and the protective cylinder 12 is sleeved on the outer side of the top of the branch pipe 9.

[0034] In this embodiment, by arranging the protective cylinder 12 on the lower surface of the mounting plate 4, the top of the branch pipe 9 is protected, avoiding the position of the branch pipe 9 being affected by obstacles in the external environment during the moving process of the device, and further avoiding the deflection of the branch pipe 9 caused by external collisions.
