Description

Technical Field

[0001] The utility model relates to the technical field of drain pipes, in particular to an anti-blocking concrete drain pipe. Background Technique

[0002] Traditional concrete drain pipes are prone to being blocked by various blocking substances such as solid particles, sediment, and plant roots during the drainage process. These blocking substances can cause the blockage of the drainage pipes, resulting in a decrease in drainage efficiency or even complete blockage, bringing serious problems to the water supply and drainage system.

[0003] The existing Chinese patent with the publication number of CN220851257U discloses a double-plug anti-blocking concrete drain pipe, including a pipe. A slot is arranged at the right end of the pipe, and a socket is arranged at the left end of the pipe. A cleaning block is embedded and installed on the left side inside the pipe. An anti-adhesion coating is brushed on the inner wall of the pipe. The middle horizontal position of the cleaning block is hollowed out. A rotating fan is rotatably installed in the middle of the cleaning block. One end of the cleaning block is movably installed with a cover plate; by setting the anti-adhesion coating, the anti-adhesion coating is an epoxy resin coating, and the epoxy resin coating is a coating with corrosion resistance and wear resistance, which can be applied to the inner wall of the concrete pipe. This coating can reduce the inner wall friction force, effectively prevent adhesion from occurring, make the inner wall of the concrete pipe smoother, reduce adhesion, reduce the accumulation of internal blocking substances, and at the same time will not affect the cross-sectional area of the drainage.

[0004] In view of the above and related existing technologies, the inventor believes that the following defects often exist: this device drives the cleaning block to reciprocate by repeatedly injecting high-pressure water flow to achieve the cleaning purpose, but this method is time-consuming and laborious, consumes water resources and human resources, and needs to be improved; therefore, an anti-blocking concrete drain pipe is proposed for the above problems. Content of the Utility Model

[0005] In order to make up for the deficiencies of the existing technology and solve the above-mentioned technical problems, the utility model proposes an anti-blocking concrete drain pipe.

[0006] The technical solution adopted by the utility model to solve its technical problems is: the utility model discloses an anti-clogging concrete drainage pipe, comprising a pipe made of concrete, the inner wall of the pipe being coated with an anti-stick coating, two sides of the inside of the pipe being fixedly connected with fixed brackets respectively, a reciprocating screw being rotatably connected at the center of the fixed bracket, a cleaning component being installed on the reciprocating screw, the cleaning component comprising a rotating seat, the rotating seat being threadedly connected to the reciprocating screw, the surface of the rotating seat being provided with blades distributed in an annular shape, the end of the blade facing the inner wall of the pipe being fixedly connected with a wear-resistant layer, when the pipe is in use, water flows through the inside of the pipe, and the impact force applied by the water flow to the blades below drives the rotating seat to reciprocate on the reciprocating screw, and then the inner wall of the pipe is cleaned through the wear-resistant layer. Compared with the prior art, the automatic cleaning of the inner wall of the pipe can be achieved, saving manpower and water resource consumption.

[0007] Preferably, the blades adopt a telescopic structure, and the blades are composed of two upper and lower slidingly connected plates. Since the water flows at the bottom of the pipe, the blades are mainly used to clean the bottom wall of the pipe. When the rotating seat rotates, the blades are automatically extended and retracted under the influence of gravity, which can shake off impurities and garbage attached to the surface, reduce the wear of the wear-resistant layer, and at the same time make up for the gaps left after the wear-resistant layer is worn.

[0008] Preferably, one end of the blade is fixedly connected to a rotating shaft, and one end of the rotating shaft is rotatably connected to a rotating seat.

[0009] Preferably, a mounting ring is installed on the outside of the rotating shaft, and the mounting ring is fixedly installed on the surface of the rotating seat. The two sides of the rotating shaft are respectively fixedly connected with a raised layer one, and the inner wall of the mounting ring is symmetrically fixedly connected with a raised layer two, and the raised layer one and the raised layer two are cross-distributed.

[0010] Preferably, springs are fixedly connected to the opposite sides of the raised layer one and the raised layer two, and the springs are used to support the raised layer one and the raised layer two, so that the blades maintain an inclined distribution, increasing the contact area with the water flow. When larger solid impurities carried in the water flow collide with the blades, the blades will rotate accordingly due to the collision to avoid hard contact, thereby reducing the impact force received and reducing the probability of blade damage.

[0011] Preferably, the fixing bracket comprises a connecting seat at the center, and connecting tubes are fixedly connected to both sides of the connecting seat.

[0012] Preferably, a threaded column is slidably connected inside the connecting tube, and a limit ring is threadedly connected on the surface of the threaded column.

[0013] Preferably, one end of the threaded post is fixedly connected with a fixing seat, and mounting holes are formed on the surface of the fixing seat. By fixing the fixing seat inside the pipeline in a way of punching and installing, the connecting cylinder and the threaded post can flexibly adjust their lengths according to the inner wall of the pipeline, so that the device is applicable to the installation requirements of pipelines with multiple sizes. And by rotating the limiting ring, after the fixing seat is installed, the total length of the connecting cylinder and the threaded post can be restricted, so that the connecting seat can be located at the center inside the pipeline, meeting the use requirements of the cleaning assembly.

[0014] The beneficial effects of the present utility model are as follows:

[0015] 1. In the present utility model, the impact force exerted by the water flow on the lower blades pushes the rotating seat to reciprocate on the reciprocating lead screw, and then the inner wall of the pipeline is cleaned through the wear-resistant layer. Compared with the prior art, it realizes the automatic cleaning of the inner wall of the pipeline, saving the consumption of manpower and water resources.

[0016] 2. In the present utility model, the connecting cylinder and the threaded post can flexibly adjust their lengths according to the inner wall of the pipeline, so that the device is applicable to the installation requirements of pipelines with multiple sizes. And by rotating the limiting ring, after the fixing seat is installed, the total length of the connecting cylinder and the threaded post can be restricted, so that the connecting seat can be located at the center inside the pipeline, meeting the use requirements of the cleaning assembly.

Specific implementation mode

[0024] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0025] Embodiment 1

[0026] Please refer to Figures 1-4 As shown, a concrete drain pipe for preventing blockage includes a pipeline 1 made of concrete. The inner wall of the pipeline 1 is coated with an anti-sticking coating. Fixed supports 2 are respectively fixedly connected to both sides inside the pipeline 1. A reciprocating lead screw 3 is rotatably connected to the center of the fixed support 2. A cleaning component 4 is installed on the reciprocating lead screw 3. The cleaning component 4 includes a rotating seat 41. The rotating seat 41 is threadedly connected to the reciprocating lead screw 3. A plurality of blades 42 distributed in a ring shape are installed on the surface of the rotating seat 41. One end of the blade 42 facing the inner wall of the pipeline 1 is fixedly connected with a wear-resistant layer 43. When the pipeline 1 is in use, water flows inside the pipeline 1. The impact force applied by the water flow to the lower blade 42 pushes the rotating seat 41 to reciprocate on the reciprocating lead screw 3, and then the inner wall of the pipeline 1 is cleaned through the wear-resistant layer 43, realizing automatic cleaning of the inner wall of the pipeline 1.

[0027] The blade 42 adopts a telescopic structure. The blade 42 is composed of two plate members that are slidably connected up and down. Since the water flow flows at the bottom of the pipeline 1, the blade 42 is designed to be telescopic to clean the bottom wall of the pipeline 1. When the blade 42 rotates on the rotating seat 41, it automatically expands and contracts under the influence of gravity, which can shake off the impurities and garbage attached to its surface, reduce the wear of the wear-resistant layer 43, and at the same time make up for the gap left after the wear of the wear-resistant layer 43.

[0028] One end of the blade 42 is fixedly connected with a rotating shaft 44, and one end of the rotating shaft 44 is rotatably connected to the rotating seat 41.

[0029] An installation ring 45 is installed outside the rotating shaft 44. The installation ring 45 is fixedly installed on the surface of the rotating seat 41. First raised layers 46 are respectively fixedly connected to both sides of the rotating shaft 44. Second raised layers 47 are symmetrically fixedly connected to the inner wall of the installation ring 45. The first raised layers 46 and the second raised layers 47 are cross-distributed.

[0030] On the opposite side of the first raised layer 46 and the second raised layer 47, a spring 48 is fixedly connected. By means of the spring 48 pressing against the first raised layer 46 and the second raised layer 47, the blade 42 is kept in an inclined distribution, increasing the contact area with the water flow. When relatively large solid impurities carried in the water flow collide with the blade 42, the blade 42 will rotate accordingly upon collision to avoid hard contact, thereby reducing the impact force received and decreasing the probability of damage to the blade 42.

[0031] Embodiment 2

[0032] Comparing with Embodiment 1, please refer to Figure 5 As shown, the present utility model provides another implementation manner. The fixed bracket 2 includes a connecting seat 21 at the center. On both sides of the connecting seat 21, connecting cylinders 22 are respectively and fixedly connected.

[0033] A threaded column 23 is slidably connected inside the connecting cylinder 22, and a limiting ring 24 is threadedly connected to the surface of the threaded column 23.

[0034] One end of the threaded column 23 is fixedly connected with a fixed seat 26. An installation hole 25 is formed on the surface of the fixed seat 26. By fixing the fixed seat 26 inside the pipeline 1 in a drilling and installation manner, the connecting cylinder 22 and the threaded column 23 can flexibly adjust the length according to the inner wall of the pipeline 1, making the device applicable to the installation requirements of pipelines 1 with multiple sizes. And by rotating the limiting ring 24, after the fixed seat 26 is installed, the total length of the connecting cylinder 22 and the threaded column 23 can be limited, so that the connecting seat 21 can be located at the center inside the pipeline 1, meeting the use requirements of the cleaning component 4.

[0035] Working principle: By fixing the fixed seat 26 inside the pipeline 1 in a drilling and installation manner, the connecting cylinder 22 and the threaded column 23 can flexibly adjust the length according to the inner wall of the pipeline 1, making the device applicable to the installation requirements of pipelines 1 with multiple sizes. And by rotating the limiting ring 24, after the fixed seat 26 is installed, the total length of the connecting cylinder 22 and the threaded column 23 can be limited, so that the connecting seat 21 can be located at the center inside the pipeline 1, meeting the use requirements of the cleaning component 4.

[0036] When the pipeline 1 is in use, water flow flows inside the pipeline 1. The impact force applied by the water flow to the lower blade 42 below pushes the rotating seat 41 to reciprocate on the reciprocating lead screw 3. Then, the inner wall of the pipeline 1 is cleaned through the wear-resistant layer 43, realizing automatic cleaning of the inner wall of the pipeline 1. When the blade 42 rotates with the rotating seat 41, it automatically expands and contracts under the influence of gravity, and can shake off the impurities and garbage attached to its surface, reducing the wear of the wear-resistant layer 43 and at the same time making up for the gap left after the wear of the wear-resistant layer 43.
