Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of municipal engineering, in particular to a rainwater diversion device for municipal water conservancy construction. Background Art
[0002] During the rainy season, municipal roads usually experience flooding, which will cause the municipal roads to be submerged and affect the normal passage of pedestrians and vehicles. Therefore, it is necessary to effectively and reasonably divert the rainwater on the road so that it can be discharged into the drainage ditch without affecting people's normal life. Nowadays, people generally use sandbag diversion methods to transfer rainwater to the drainage ditch, or choose to open an outlet pipe on the road surface to collect rainwater, and install a drainage manhole cover above the outlet pipe for drainage.
[0003] With respect to the above-mentioned related technologies, the inventor believes that there are the following defects: the existing diversion device guides the water on the road surface into the sewer. During this process, when the sewer is blocked, too much rainwater accumulates in the sewer. At this time, rainwater flows back, causing urban waterlogging, thus affecting the urban environment. Utility Model Content
[0004] In order to solve the above problems, the utility model provides a rainwater diversion device for municipal water conservancy construction.
[0005] The above technical purpose of the utility model is achieved through the following technical scheme: a rainwater diversion device for municipal water conservancy construction, including a sewer pipe, a connecting piece is installed on the side wall of the sewer pipe, a through hole is penetrated through the side wall of the connecting piece, a connecting pipe is installed at the end of the connecting piece away from the sewer pipe, the sewer pipe, the through hole and the connecting pipe are opposite to each other, and an anti-backflow device for reducing rainwater backflow is provided on the connecting piece.
[0006] By adopting the above technical solution, rainwater on the road surface flows into the through hole through the connecting pipe, and then flows into the sewer pipe through the connecting piece. During this process, when the sewer pipe is blocked, the anti-backflow device blocks the rainwater in the sewer pipe, thereby reducing the probability of rainwater in the sewer pipe flowing into the connecting pipe again, thereby reducing the probability of waterlogging.
[0007] Furthermore, reset grooves are provided on two opposite inner walls of the through hole, and the backflow prevention device includes a first semicircular plate fixedly arranged on the inner wall of the through hole, a second semicircular plate rotatably arranged in the through hole, and two torsion springs respectively fixedly arranged on the inner walls of the two reset grooves, the other ends of the two torsion springs are fixedly arranged on the side wall of the second semicircular plate, and the side wall of the first semicircular plate away from the connecting pipe abuts against the side wall of the second semicircular plate close to the connecting pipe.
[0008] By adopting the above technical solution, when rainwater flows into the through hole through the connecting pipe, the second semicircular plate rotates under the action of the water flow, so that the rainwater flows into the connecting pipe. Subsequently, when the rainwater flows out, the second semicircular plate is reset under the action of the torsion spring. In addition, when the sewer pipe is blocked, the rainwater in the sewer pipe flows into the through hole. At this time, since the side wall of the first semicircular plate away from the connecting pipe abuts against the side wall of the second semicircular plate close to the connecting pipe, the second semicircular plate blocks the rainwater, thereby reducing the probability of rainwater in the sewer pipe flowing into the connecting pipe again, thereby reducing the probability of waterlogging.
[0009] Furthermore, the upper end of the second semicircular plate is provided with a rounded corner.
[0010] By adopting the above technical solution, the rounded corners reduce the probability of the second semicircular plate colliding with the first semicircular plate during rotation, thereby reducing the probability of the second semicircular plate getting stuck during rotation, thereby improving the stability of the device.
[0011] Furthermore, a first flange is fixedly provided on two opposite side walls of the connecting member, a second flange is fixedly provided on the side walls where the downcomer pipe and the connecting pipe are close to each other, and the first flange and the second flange are fixed to each other by bolts.
[0012] By adopting the above technical solution, when the backflow prevention device is damaged, the staff disassembles the connecting piece through the first flange and the second flange. Then, the staff repairs the backflow prevention device, thereby reducing the difficulty of the staff repairing the backflow prevention device, thereby reducing the difficulty of the staff's work.
[0013] Furthermore, a backflow prevention plug with a trapezoidal cross section is installed in the connecting pipe, the upper end of the backflow prevention plug is fixed to the inner wall of the connecting pipe, and the bottom end of the backflow prevention plug is abutted against the inner wall of the connecting pipe.
[0014] By adopting the above technical solution, when rainwater flows in the connecting pipe, the bottom end of the anti-backflow plug abuts against the inner wall of the connecting pipe, causing the rainwater to flow into the through hole. In this process, the probability of backflow when the anti-backflow device is damaged is reduced.
[0015] Furthermore, a mounting groove is provided on the side wall of the backflow prevention plug.
[0016] By adopting the above technical solution, the side wall of the anti-backflow plug is provided with a mounting groove, which reduces the weight of the anti-backflow plug and further reduces the difficulty of rainwater flowing into the through hole.
[0017] Furthermore, the anti-backflow plug is made of rubber material.
[0018] By adopting the above technical solution, the rubber has good elasticity, and the rubber plug made of rubber material further reduces the difficulty of rainwater flowing into the through hole.
[0019] In summary, the utility model has the following beneficial effects:
[0020] 1. In the present application, rainwater on the road flows into the through hole through the connecting pipe, and then flows into the sewer pipe through the connecting piece. During this process, when the sewer pipe is blocked, the anti-backflow device blocks the rainwater in the sewer pipe, thereby reducing the probability of rainwater in the sewer pipe flowing into the connecting pipe again, thereby reducing the probability of waterlogging;
[0021] 2. In the present application, when rainwater flows into the through hole through the connecting pipe, the second semicircular plate rotates under the action of the water flow, thereby causing the rainwater to flow into the connecting pipe. Subsequently, when the rainwater has flowed out, the second semicircular plate is reset under the action of the torsion spring. In addition, when the sewer pipe is blocked, the rainwater in the sewer pipe flows into the through hole. At this time, since the side wall of the first semicircular plate away from the connecting pipe abuts against the side wall of the second semicircular plate close to the connecting pipe, the second semicircular plate blocks the rainwater, thereby reducing the probability of rainwater in the sewer pipe flowing into the connecting pipe again, thereby reducing the probability of waterlogging;
[0022] 3. In the present application, the rounded corners reduce the probability of the second semicircular plate colliding with the first semicircular plate during rotation, thereby reducing the probability of the second semicircular plate getting stuck during rotation, thereby improving the stability of the device.

DETAILED DESCRIPTION
[0027] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application; obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments, and all other embodiments obtained by ordinary technicians in this field based on the embodiments in the present application without making creative work are within the scope of protection of the present application.
[0028] like Figure 1-3 As shown, the embodiment of the present application discloses a rainwater diversion device for municipal water conservancy construction, including a sewer pipe 1, a connector 11, a connecting pipe 12, an anti-backflow device 3, a first flange 5, a second flange 51, a bolt 52 and an anti-backflow plug 6. The sewer pipe 1 is a circular tubular structure, and its axis is horizontal. The connecting member 11 is a cylindrical structure, and its axis coincides with the axis of the sewer pipe 1. The connecting member 11 is installed on the side wall of the sewer pipe 1, and a through hole 2 is opened through the side wall of the connecting member 11. The connecting pipe 12 is a circular tubular structure, and its axis coincides with the axis of the sewer pipe 1. The connecting pipe 12 is installed at one end of the connecting member 11 away from the sewer pipe 1, and the sewer pipe 1, the through hole 2 and the connecting pipe 12 are directly opposite.
[0029] Rainwater on the road surface flows into the through hole 2 through the connecting pipe 12, and then flows into the sewer pipe 1 through the connecting piece 11. During this process, when the sewer pipe 1 is blocked, the anti-backflow device 3 blocks the rainwater in the sewer pipe 1, thereby reducing the probability of rainwater in the sewer pipe 1 flowing into the connecting pipe 12 again, thereby reducing the probability of waterlogging.
[0030] Reset grooves 21 are provided on two opposite inner walls of the through hole 2. The backflow prevention device 3 is arranged on the connecting piece 11 to reduce the backflow of rainwater. The backflow prevention device 3 includes a first semicircular plate 31, a second semicircular plate 32 and a reset spring. The cross section of the first semicircular plate 31 is semicircular, and the first semicircular plate 31 is fixedly arranged on the inner wall of the through hole 2. The cross section of the second semicircular plate 32 is semicircular, and the second semicircular plate 32 is rotatably arranged in the through hole 2, and the side wall of the first semicircular plate 31 away from the connecting pipe 12 abuts against the side wall of the second semicircular plate 32 close to the connecting pipe 12. Two torsion springs 33 are provided, one end of the two torsion springs 33 is respectively fixedly arranged on the inner walls of the two reset grooves 21, and the other ends of the two torsion springs 33 are fixedly arranged on the side wall of the second semicircular plate 32.
[0031] When rainwater flows into the through hole 2 through the connecting pipe 12, the second semicircular plate 32 rotates under the action of the water flow, so that the rainwater flows into the connecting pipe 12. Then, when the rainwater flows out, the second semicircular plate 32 is reset under the action of the torsion spring 33. In addition, when the sewer pipe 1 is blocked, the rainwater in the sewer pipe 1 flows into the through hole 2. At this time, since the side wall of the first semicircular plate 31 away from the connecting pipe 12 abuts against the side wall of the second semicircular plate 32 close to the connecting pipe 12, the second semicircular plate 32 blocks the rainwater, thereby reducing the probability of rainwater in the sewer pipe 1 flowing into the connecting pipe 12 again, thereby reducing the probability of waterlogging.
[0032] In order to improve the stability of the device, the upper end of the second semicircular plate 32 is provided with a rounded corner 4. The rounded corner 4 reduces the probability of the second semicircular plate 32 colliding with the first semicircular plate 31 when rotating, thereby reducing the probability of the second semicircular plate 32 getting stuck during rotation, thereby improving the stability of the device.
[0033] The first flange 5 is an annular structure, and its axis coincides with the axis of the connecting pipe 12. Two first flanges 5 are provided and fixedly mounted on two opposite side walls of the connecting member 11. The second flange 51 is an annular structure, and its axis coincides with the axis of the connecting pipe 12. Two second flanges 51 are provided and fixedly mounted on the side walls of the sewer pipe 1 and the connecting pipe 12 that are close to each other. The first flange 5 and the second flange 51 are fixedly mounted on each other by bolts 52.
[0034] When the backflow prevention device 3 is damaged, the staff disassembles the connector 11 through the first flange 5 and the second flange 51. Subsequently, the staff repairs the backflow prevention device 3, thereby reducing the difficulty of the staff repairing the backflow prevention device 3, thereby reducing the difficulty of the staff's work.
[0035] The cross section of the anti-backflow plug 6 is trapezoidal. The anti-backflow plug 6 is installed in the connecting pipe 12. The upper end of the anti-backflow plug 6 is fixed to the inner wall of the connecting pipe 12, and the bottom end of the anti-backflow plug 6 abuts against the inner wall of the connecting pipe 12.
[0036] When rainwater flows in the connecting pipe 12, the bottom end of the anti-backflow plug 6 abuts against the inner wall of the connecting pipe 12, causing the rainwater to flow into the through hole 2. In this process, the probability of backflow when the anti-backflow device 3 is damaged is reduced.
[0037] In order to reduce the difficulty of rainwater flowing into the through hole 2, a mounting groove 7 is provided on the side wall of the anti-backflow plug 6. The mounting groove 7 is provided on the side wall of the anti-backflow plug 6 to reduce the weight of the anti-backflow plug 6, thereby reducing the difficulty of rainwater flowing into the through hole 2.
[0038] In order to reduce the difficulty of rainwater flowing into the through hole 2, the anti-backflow plug 6 is made of rubber material. Rubber has good elasticity, and the rubber plug made of rubber material further reduces the difficulty of rainwater flowing into the through hole 2.
[0039] The use principle of a rainwater diversion device for municipal water conservancy construction in this embodiment is as follows: rainwater on the road surface flows into the through hole 2 through the connecting pipe 12, and the second semicircular plate 32 rotates under the action of the water flow, thereby causing the rainwater to flow into the connecting pipe 12. Subsequently, when the rainwater has flowed out, the second semicircular plate 32 is reset under the action of the torsion spring 33. In addition, when the sewer pipe 1 is blocked, the rainwater in the sewer pipe 1 flows into the through hole 2. At this time, since the side wall of the first semicircular plate 31 away from the connecting pipe 12 abuts against the side wall of the second semicircular plate 32 close to the connecting pipe 12, the second semicircular plate 32 blocks the rainwater, thereby reducing the probability of the rainwater in the sewer pipe 1 flowing into the connecting pipe 12 again, thereby reducing the probability of waterlogging.
[0040] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
