Description

Technical Field

[0001] The invention relates to the technical field of drainage facilities for building construction, and in particular to an overhead drainage device with a self-slope finding function. Background Art

[0002] With the rapid development of the construction industry, the design and construction of drainage ditches are of great significance to the protection of the ecological environment. The main construction method of traditional drainage ditches relies on manual brickwork, which has a long construction period, low economic cost and finished product quality. In addition, brick-built drainage ditches have poor anti-seepage and anti-corrosion capabilities, and are not easy to dismantle and reuse. At the same time, traditional drainage ditches are usually rectangular water-passing sections. This design easily leaves dead corners, making cleaning and maintenance difficult. It is necessary to comprehensively consider various factors and take corresponding measures to solve these problems. Summary of the invention

[0003] In order to solve the above problems, the present invention discloses a drainage overhead device with a slope-finding function, including a corrugated pipe, and a half structure left by axial sectioning of the corrugated pipe, the upper end of the corrugated pipe is covered with a cover plate, and brackets are provided at the lower parts of both sides of the corrugated pipe. The corrugated pipe adopts the existing sewage corrugated pipe, which can improve the anti-seepage and anti-corrosion capabilities of the drainage ditch. At the same time, the bracket is adopted, which can be easily erected and the drainage channel can be quickly built.

[0004] The bracket includes a first support tube and a second support tube, and the second support tube extends from the upper end of the first support tube. That is, the height of the support leg formed by the first support tube and the second support tube can be adjusted. When multiple brackets are adjusted, the bellows can be tilted, that is, the slope operation can be performed, which is convenient for drainage.

[0005] A U-shaped spring piece is provided inside the second support tube, one end of which is fixedly connected to a convex point, and a plurality of button holes are provided at equal distances on the side wall of the first support tube, and the button holes and the convex points cooperate. Under the action of the U-shaped spring piece, the convex point moves away from the axis of the second support tube, that is, the convex point remains in the button hole, so that the height of the support leg is limited. When the convex point is pressed so that the convex point is out of the button hole, the height of the support leg can be adjusted.

[0006] Preferably, the bracket further comprises an arc-shaped support ring, and the arc-shaped support ring supports the side wall of the corrugated pipe, and the upper end of the second support pipe is rotatably connected to the end of the arc-shaped support ring. During use, the water flow impacts the corrugated pipe, which causes the corrugated pipe to shake, and the contact area between the arc-shaped support ring and the corrugated pipe is inevitably worn, so a layer of rubber pad is required between the arc-shaped support ring and the corrugated pipe.

[0007] Preferably, a cross bar is provided at the ends of the same side of the adjacent arc-shaped support rings, and both ends of the cross bar are provided with long holes, and the arc-shaped support ring is interspersed with rods, and the rods are fitted in the long holes. The cross bar realizes the connection between the two brackets, improves the support stability of the corrugated pipe, and the long holes provided on the cross bar are used to balance the change in the distance between the two brackets when the corrugated pipe is tilted.

[0008] Preferably, a telescopic rod is fixedly connected to the lower side wall of the first support tube, and the other end of the telescopic rod is fixedly connected to the side wall of the adjacent first support tube. The telescopic rod is composed of at least two nested rods, and the telescopic rod and the cross bar have the same function, which is to improve the support stability of the corrugated tube, and the long hole provided on the cross bar is used to balance the change in the distance between the two brackets when the corrugated tube is tilted.

[0009] Preferably, a pin is inserted into one end of the U-shaped spring piece, and the other end of the pin is inserted into the side wall of the second support tube. The pin is used to archive the U-shaped spring piece. If the elastic force of the U-shaped spring piece decreases and does not meet the limit of the support leg, the pin can be removed and replaced.

[0010] Preferably, one end of the bellows is set with a reduced diameter and the other end is set with an expanded diameter, and adjacent bellows are set end to end. When building this device, it is necessary to build it according to the actual drainage distance, that is, the number of bellows to be built is determined by the actual distance. When multiple bellows are built, they are built end to end, and structural glue needs to be applied to the overlapping area to avoid water leakage.

[0011] Preferably, a water flow hole is provided in the middle of the cover plate.

[0012] The beneficial effects of the present invention are as follows:

[0013] 1. The drainage overhead device can be quickly installed and disassembled, and is ready for use. It is also relatively simple to manufacture. Compared with brick-built drainage ditches, the present invention has a high turnover rate and obvious economic benefits.

[0014] 2. The adjustable legs can achieve quick slope finding, easy operation, and save manpower and material resources. At the same time, the inclination angle of the corrugated pipe can also be adjusted in later use. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. It should be understood that the following specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention. It should be noted that the words "front", "rear", "left", "right", "upper" and "lower" used in the following description refer to directions in the accompanying drawings, and the words "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0022] like Figure 1 As shown, an overhead drainage device with a slope-adjusting function comprises a bellows 1, and a half structure left by axially sectioning the bellows 1. The upper end of the bellows 1 is covered with a cover plate 2, and the cover plate 2 is used to seal the upper part of the bellows 1. At the same time, a convex edge is provided on the edge of the bellows 1 to limit the cover plate 2 on the bellows 1. Brackets 3 are provided at the lower parts of both sides of the bellows 1 to support the bellows.

[0023] like Figure 2 As shown, the bracket 3 includes a first support tube 31 and a second support tube 34, and the first support tube 31 and the second support tube 34 constitute the structure of a support leg, and the second support tube 34 extends from the upper end of the first support tube 31, that is, the support leg can adjust its height, and further, the inclination angle of the corrugated tube 1 can be adjusted, that is, it has the function of slope finding.

[0024] like Figure 3 As shown, a U-shaped spring piece 36 is arranged inside the second support tube 34, and the U-shaped spring piece 36 is pre-tightened and gathered inside the second support tube 34. One end of the U-shaped spring piece 36 is fixedly connected with a protrusion 33, that is, under the action of the U-shaped spring piece 36, the protrusion 33 moves away from the second support 34 axis direction, and a plurality of buckle holes 32 are arranged on the side wall of the first support tube 31 at equal distances, and the buckle holes 32 and the protrusions 33 cooperate. When the protrusions 33 cooperate in the buckle holes 32, the relative position between the first support tube 31 and the second support tube 34 is limited, that is, the height of the support leg is limited. If adjustment is required, the protrusion 33 is pressed to separate it from the buckle hole 32, and the height can be adjusted.

[0025] like Figure 2As shown, the bracket 3 also includes an arc-shaped support ring 35, and the arc-shaped support ring 35 supports the side wall of the bellows 1, and a rubber pad is arranged between the arc-shaped support ring 35 and the bellows 1 to avoid wear between the two. The upper end of the second support tube 34 is rotatably connected to the end of the arc-shaped support ring 35. The bracket 3 needs to maintain a vertical state, but when the bellows 1 is tilted and adjusted, the angle between the second support tube 34 and the bellows 1 changes, so a rotating connection method is adopted here.

[0026] Combination Figure 1 and Figure 2 As shown, the ends of the same side of the adjacent arc-shaped support rings 35 are provided with cross bars 5, and both ends of the cross bars 5 are provided with long holes, and rods are inserted into the arc-shaped support rings 35, and the rods are fitted in the long holes. The cross bars 5 and the rods are in a movable fit. The lower side wall of the first support tube 31 is fixedly connected with a telescopic rod 4, and the other end of the telescopic rod 4 is fixedly connected to the side wall of the adjacent first support tube 31. The telescopic rod 4 is formed by at least two nested rods. The long holes set at both ends of the cross bar 5 and the telescopic rod 4 are consistent in function, ensuring the stability of the support and not affecting the angle adjustment of the corrugated tube 1.

[0027] like Figure 3 As shown, a pin rod 37 is inserted into one end of the U-shaped spring piece 36 , and the other end of the pin rod 37 is inserted into the side wall of the second support tube 34 . The U-shaped spring piece 36 can be removed by removing the pin rod 37 .

[0028] One end of the corrugated pipe 1 is set with a reduced diameter, and the other end is set with an expanded diameter, and adjacent corrugated pipes 1 are arranged end to end to overlap, so as to realize the connection between multiple corrugated pipes 1, and structural adhesive needs to be added at the connection when connecting.

[0029] A water flow hole is arranged in the middle of the cover plate 2 .

[0030] The technical means disclosed in the scheme of the present invention are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical schemes composed of any combination of the above technical features.
