Description

Technical Field

[0001] The present application relates to the technical field of drainage, and in particular to a drainage pipe capable of preventing blockage. Background Art

[0002] Drainage pipes are essential structures in buildings and roads. Domestic or industrial sewage or wastewater enters the sewage treatment plant through drainage pipes, where it is purified and reused.

[0003] The sewage or wastewater transported by the drainage pipe contains a large amount of insoluble impurities, which may cause blockage in the drainage pipe, thereby affecting the normal drainage. Therefore, it is necessary to clean the drainage pipe when it is blocked. CN113089781A discloses an anti-blocking drainage pipe, which lowers a scraper after the pipe is blocked and presses the scraper downward under the action of water pressure to discharge the impurities blocked below.

[0004] Although the above patent is convenient to use, the water injected into the pipe will not flow after the pipe is blocked, so it is difficult to drive the scraper to move downward, resulting in an unsatisfactory cleaning effect on impurities. Utility Model Content

[0005] The embodiment of the present application provides a drainage pipe that prevents blockage, so as to solve the problem in the prior art that it is difficult to drive the scraper to move by injecting water.

[0006] An embodiment of the present application provides a drainage pipe that prevents blockage, including a cleaning device, wherein two ends of the cleaning device are respectively connected to a water inlet pipe and a drainage pipe, the cleaning device includes a shell, a scraper, a driving rod, an upper pull rope and a lower pull rope, the scraper is vertically rotatable and connected to the inner side surface of the shell, the driving rod is horizontally rotatable and connected to the outer side surface of the shell, one end of the upper pull rope is fixed to the driving rod, the other end is wound around the driving rod and then passes through the shell and is connected to one side of the scraper, one end of the lower pull rope is fixed to the driving rod, the other end is wound around the driving rod and then passes through the shell and is connected to the other side of the scraper, the upper pull rope and the lower pull rope are wound on the driving rod in opposite directions, and the positions where the upper pull rope and the lower pull rope pass through the shell are respectively located above and below the rotation point of the scraper.

[0007] In one possible implementation, an inner cavity is provided inside the side wall of the shell at a position corresponding to the scraper, one end of the driving rod is rotatably connected to the inner side surface of the inner cavity close to the scraper, and the other end of the driving rod passes through the side of the inner cavity away from the scraper to the outside of the shell, and the upper pull rope and the lower pull rope are both connected and wound on the side of the driving rod located inside the inner cavity.

[0008] In a possible implementation manner, an operating head is provided at one end of the driving rod that passes through the outside of the shell.

[0009] In a possible implementation, the shell is a cylindrical structure, the scraper is a rod-shaped structure, and multiple scrapers are arranged on the inner side of the shell, and a driving rod, an upper pull rope and a lower pull rope are arranged at a position corresponding to each scraper on the shell.

[0010] In a possible implementation, the shell is a quadrangular prism structure, the scraper is a rectangular plate, and the cross-sectional shape of the scraper in the longitudinal direction is the same as the radial cross-sectional shape of the shell.

[0011] In a possible implementation, a groove is provided on the inner side surface of the shell, and the scraper is located in the groove when being pulled to a vertical position by the upper pull rope.

[0014] A drainage pipe for preventing blockage in the present application has the following advantages:

[0015] The pull ropes are wound in opposite directions on the driving rod. When the drainage pipe is unobstructed, the upper pull rope pulls the hanging plate to a vertical state without affecting the flow of water. When the drainage pipe is blocked, the lower pull rope pulls the scraper downward, and the upper pull rope is gradually loosened, so that the scraper rotates downward to press the impurities blocked below downward, thereby discharging the impurities. The present application pulls the scraper by the upper and lower pull ropes respectively, so that the scraper can obtain sufficient power when rotating upward and downward, ensuring that the cleaning work of impurities in the drainage pipe can be carried out smoothly.

[0021] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0022] Figure 1-3 A schematic diagram of a drainage pipe for preventing blockage provided in an embodiment of the present application. An embodiment of the present application provides a drainage pipe for preventing blockage, including:

[0023] The cleaning device 100 has two ends connected to the water inlet pipe 200 and the drain pipe 300 respectively. The cleaning device 100 includes a housing 110, a scraper 120, a driving rod 130, an upper pull rope 140 and a lower pull rope 150. The scraper 120 is vertically rotatably connected to the inner side of the housing 110, the driving rod 130 is horizontally rotatably connected to the outer side of the housing 110, one end of the upper pull rope 140 is fixed to the driving rod 130, and the other end is wound around the driving rod 130 and then pass through the shell body 110 and are connected to one side of the scraper 120, one end of the pull-down rope 150 is fixed on the driving rod 130, and the other end is wound on the driving rod 130 and then pass through the shell body 110 and are connected to the other side of the scraper 120, the winding directions of the upper pull rope 140 and the lower pull rope 150 on the driving rod 130 are opposite, and the positions where the upper pull rope 140 and the lower pull rope 150 pass through the shell body 110 are respectively located above and below the rotation point of the scraper 120.

[0024] For example, a horizontal rotating shaft is provided on the inner side of the housing 110, and the scraper 120 is rotatably plugged on the rotating shaft, so that the scraper 120 can rotate up and down inside the housing 110, thereby squeezing the space inside the housing 110 below the rotating shaft to achieve the effect of cleaning impurities. The housing 110 is provided with an upper through hole and a lower through hole, and the upper pull rope 140 and the lower pull rope 150 pass through the upper through hole and the lower through hole respectively, and the upper through hole and the lower through hole are respectively located above and below the rotating shaft, so that the pull rope extending from the driving rod 130 passes through the two through holes respectively, and when the pull rope is tightened, a corresponding direction, that is, upward or downward pulling force can be applied to the scraper 120, so that the scraper 120 can be pulled to rotate upward or downward.

[0025] Furthermore, since water will flow through the inside of the shell 110 after the shell 110 and the water inlet pipe 200 are connected, the present application also provides a sealing component in the upper through hole and the lower through hole. The sealing component can be a rubber ring, which is sleeved inside the through hole, and the pull rope passes through the rubber ring, thereby reducing or even avoiding water seepage in the shell 110 while meeting the pull rope movement requirements.

[0026] Furthermore, one end of the driving rod 130 has a thrust ring, which is embedded in the side wall of the shell 110, so that the driving rod 130 can only rotate in the circumferential direction but cannot move in the axial direction, thereby reducing the activity space of the driving rod 130 and reducing the space occupied when cleaning impurities.

[0027] The upper pull rope 140 and the lower pull rope 150 can be made of nylon rope, one end of which is connected to one end of the scraper 120 on the driving rod 130, and the other end is wound around the driving rod 130 for multiple turns, then passes through the side wall of the housing 110 and is connected to two opposite sides of the scraper 120. Since the winding directions of the upper pull rope 140 and the lower pull rope 150 are opposite, when the driving rod 130 rotates, one of the upper pull rope 140 and the lower pull rope 150 is tightened, and the other must be loosened, and the scraper 120 will rotate toward the tightened pull rope side.

[0028] In a possible embodiment, an inner cavity 112 is provided inside the side wall of the shell 110 at a position corresponding to the scraper 120, one end of the driving rod 130 is rotatably connected to the inner side surface of the inner cavity 112 close to the scraper 120, and the other end of the driving rod 130 passes through the side of the inner cavity 112 away from the scraper 120 to the outside of the shell 110, and the upper pull rope 140 and the lower pull rope 150 are both connected and wound on the side of the driving rod 130 located inside the inner cavity 112.

[0029] For example, after the inner cavity 112 is provided, the pull cord and the majority of the driving rod 130 can be placed in a relatively stable environment in the inner cavity 112, thereby reducing the adverse effects of the harsh environment such as humidity and high temperature outside the housing 110 on the pull cord and the driving rod 130. Moreover, after the pull cord is hidden inside the inner cavity 112, the overall aesthetics of the cleaning device 100 is also improved.

[0030] In a possible embodiment, an operating head 131 is provided at one end of the driving rod 130 that passes through the outside of the housing 110 .

[0031] Exemplarily, the operating head 131 may have a butterfly-shaped or annular handle to facilitate manual rotation by an operator, or the operating head 131 may have a hexagonal prism structure to facilitate rotation by an operator using a wrench.

[0032] In a possible embodiment, the housing 110 is a cylindrical or quadrangular prism structure.

[0033] Exemplarily, when the shell 110 is a cylindrical structure, the scraper 120 is a rod-shaped structure, and a plurality of scrapers 120 are arranged on the inner side of the shell 110, and a driving rod 130, an upper pull rope 140, and a lower pull rope 150 are arranged at positions corresponding to each scraper 120 on the shell 110. After a plurality of scrapers 120 are arranged, each scraper 120 can be rotated in sequence to squeeze the impurities directly below each scraper 120 downward, thereby achieving the purpose of cleaning. After the rod-shaped scraper 120 is arranged inside the shell 110 with a cylindrical structure, the scraper 120 can be rotated upward to a vertical position to be close to the inner side of the shell 110, thereby reducing the impact on the water flowing inside the shell 110 and avoiding the formation of additional blockage points inside the shell 110 due to the existence of the scraper 120.

[0034] The housing 110 is a quadrangular prism structure, the scraper 120 is a rectangular plate, and the lengthwise cross-sectional shape of the scraper 120 is the same as the radial cross-sectional shape of the housing 110. After the scraper 120 with a rectangular plate structure is adopted, the scraper 120 can completely block the interior of the housing 110 during the downward rotation process, thereby squeezing the impurities below to the maximum extent.

[0035] In a possible embodiment, a groove 111 is provided on the inner side surface of the housing 110 , and the scraper 120 is located in the groove 111 when being pulled to a vertical position by the upper pull rope 140 .

[0036] Exemplarily, the size of the groove 111 matches the scraper 120, and when the scraper 120 is rotated upward to a vertical position and is located inside the groove 111, the surface of the scraper 120 facing the inside of the shell 110 is flush with the inner side of the shell 110 to reduce the impact on the water flow inside the shell 110.

[0037] In a possible embodiment, joints are respectively provided at the upper end and the lower end of the shell 110, and the water inlet pipe 200 and the drain pipe 300 are respectively connected to the two joints.

[0038] Exemplarily, when the shell 110, the water inlet pipe 200 and the drain pipe 300 are all made of metal, threads can be set on the joint, and accordingly, threads also need to be set on the outer side surfaces of the ends of the water inlet pipe 200 and the drain pipe 300. After wrapping the raw tape on the threads of the water inlet pipe 200 and the drain pipe 300, the shell 110, the water inlet pipe 200 and the drain pipe 300 can be screwed together.

[0039] When the shell 110, the water inlet pipe 200 and the drain pipe 300 are all made of heat-meltable materials such as PVC and PPR, the joint can also be a smooth surface, and the three can be connected together by hot-melting the joint and the ends of the water inlet pipe 200 and the drain pipe 300.

[0040] Although the preferred embodiments of the present application have been described, those skilled in the art may make additional changes and modifications to these embodiments once they have learned the basic creative concept. Therefore, the appended claims are intended to be interpreted as including the preferred embodiments and all changes and modifications falling within the scope of the present application.

[0041] Obviously, those skilled in the art can make various changes and modifications to the present application without departing from the spirit and scope of the present application. Thus, if these modifications and variations of the present application fall within the scope of the claims of the present application and their equivalents, the present application is also intended to include these modifications and variations.
