Description

Technical Field

[0001] The utility model relates to the technical field of PVC drainage pipes, in particular to a PVC drainage pipe with a sewage discharge component. Background Art

[0002] Drain pipes play an important role in daily life. Drinking water, daily sewage, rainwater, etc. are all supplied or discharged through drainage pipes. Compared with cast iron drainage pipes, which are not corrosion-resistant, and stainless steel drainage pipes, which are expensive and difficult to transport, plastic drainage pipes have the advantages of low cost, convenient transportation, and stable performance. They have been increasingly used in the field of drainage pipes. Currently, PVC drainage pipes are widely used.

[0003] The Chinese patent with authorization announcement number CN219712724U discloses a PVC drain pipe with a sewage discharge component, including: an L-shaped PVC drain pipe, a through hole is opened on the surface of the lower end of the L-shaped PVC drain pipe, and an external threaded sleeve is fixedly installed on the top of the through hole. The utility model is equipped with a sealing cover, a filter screen, a scraping and sweeping component and other components. The anti-slip ring on the surface of the sealing cover facilitates the twisting of the sealing cover, which is convenient for regular cleaning of debris inside the PVC drain pipe. When cleaning the debris inside the PVC drain pipe, the filter screen and the L-shaped filter plate under the sealing cover are taken out from the inside of the L-shaped PVC drain pipe, and then the scraper is pressed to make the scraper scrape the dirt on the surface of the filter screen, and the dirt falls on the surface of the L-shaped filter plate. Finally, the dirt scraped off the surface of the L-shaped filter plate is poured out for cleaning, so that the dirt can be cleaned, the blockage of the pipeline is avoided, and the dirt inside the pipeline is convenient to clean.

[0004] However, when using the PVC drain pipe, the above solution manually presses the scraper to vertically scrape away debris, which has a low cleaning efficiency and may cause dirt to remain. During the vertical scraping process, the dirt may be compacted or difficult to completely remove, and the user cannot directly observe the dirt accumulation inside the pipe. If too much dirt accumulates and is not discovered in time, it may cause pipe blockage or reduced drainage efficiency, thereby affecting the normal operation of the drainage system. Therefore, a PVC drain pipe with a sewage discharge component is proposed to solve the above-mentioned problems. Utility Model Content

[0005] Based on the existing technical problem that when using PVC drainage pipes, debris is scraped off vertically by manually pressing a scraper, the cleaning efficiency is low, dirt may remain, and the user cannot directly observe the dirt accumulation inside the pipe. If the dirt accumulates too much, it may cause pipe blockage, the utility model proposes a PVC drainage pipe with a sewage discharge component.

[0006] A PVC drain pipe with a sewage discharge component proposed by the utility model includes a PVC water pipe, and a sewage discharge device is arranged inside the PVC water pipe. The sewage discharge device includes a filter screen, and the filter screen intercepts sundries in the sewage.

The intercepted sundries will fall into the sewage discharge pipe, and the liquid level sensor will monitor the accumulation of these sundries in real time. The transparent observation window allows the user to directly view the sewage state in the pipeline and the working condition of the filter screen.

[0012] Preferably, the cleaning device further includes a motor, the motor is fixedly installed on the inner wall of the PVC water pipe, and a rotating rod is fixedly installed on the output shaft of the motor.

[0013] Through the above technical solution, the motor is fixedly installed with the PVC water pipe to fix it. The motor drives the rotating rod to rotate so as to drive the driving bevel gear fixedly installed with the rotating rod to rotate.

[0014] Preferably, an electromagnet is rotatably connected to the outer surface of the rotating rod. The inner wall of the groove of the electromagnet is magnetically connected to the outer surface of the rotating rod through an adsorbing member, and a threaded rod is fixedly installed on the outer surface of the electromagnet.

[0015] Through the above technical solution, while the rotating rod is rotatably connected to the electromagnet, it is magnetically connected through the adsorbing member. When the electromagnet is energized, the rotating rod drives the electromagnet to rotate and at the same time drives the threaded rod fixedly installed with the electromagnet to rotate so as to drive the sleeve rod to lift through the sleeve.

The outer surface of the sleeve rod is rotatably connected to the outer surface of the scraping frame. A rotating bevel gear is fixedly installed on the outer surface of the scraping frame.

[0017] Through the above technical solution, the threaded rod is threadedly connected to the sleeve, driving it to rotate and lift. Through the rotational connection between the sleeve and the sleeve rod, it only moves up and down, thereby driving the scraping frame rotatably connected to the sleeve rod to move up and down. The scraping frame is fixedly installed with the rotating bevel gear, driving it to move up and down. When it descends to a certain position, it meshes with the driving bevel gear, driving the scraping frame to rotate and cleaning the filter net.

By setting up a cleaning device to clean the debris on the filter screen, the motor drives the rotating rod to rotate, the rotating rod drives the driving bevel gear to rotate, the rotating rod is rotatably connected to the electromagnet and magnetically connected through the adsorbent. When the electromagnet is energized, the rotating rod drives the electromagnet to rotate, and at the same time drives the threaded rod fixedly installed on the electromagnet to rotate. The threaded rod is threadedly connected to the sleeve, driving it to rotate and lift. Since the sleeve is rotatably connected to the sleeve rod, it only moves up and down, thereby driving the scraper frame rotatably connected to the sleeve rod to move up and down.

[0030] Inside the PVC water pipe 1, a cleaning device is provided. The cleaning device includes a scraping frame 62, and the rotation of the scraping frame 62 cleans the debris on the filter screen 31.

[0031] To allow users to adjust or completely close the sewage pipe 2 as needed, the sewage discharge device further includes a sewage pipe 2 with a valve. The outer surface of the sewage pipe 2 is fixedly connected to the outer surface of the PVC water pipe 1. Through the fixed connection between the sewage pipe 2 and the PVC water pipe 1, the valve allows users to adjust or completely close the sewage pipe 2 as needed, providing more flexible sewage discharge control.

The intercepted debris will fall into the sewage pipe 2, and the liquid level sensor 3 will monitor the accumulation of this debris in real time. The transparent observation window 32 allows users to directly view the sewage state inside the pipeline and the working condition of the filter screen 31.

[0033] By setting up the sewage discharge device to intercept the debris in the sewage, through the fixed connection between the sewage pipe 2 and the PVC water pipe 1, the valve allows users to adjust or completely close the sewage pipe 2 as needed, providing more flexible sewage discharge control. The filter screen 31 is fixed to the inner wall of the PVC water pipe 1 to intercept larger debris and prevent it from entering the pipeline. The intercepted debris will fall into the sewage pipe 2, and the liquid level sensor 3 will monitor the accumulation of this debris in real time. The transparent observation window 32 allows users to directly view the sewage state inside the pipeline and the working condition of the filter screen 31, solving the technical problem that when using a PVC drainage pipe, users cannot directly observe the accumulation of dirt inside the pipeline. If the dirt accumulates too much and is not discovered in time, it may cause the pipeline to be blocked or the drainage efficiency to decrease, thus affecting the normal operation of the drainage system.

[0034] To clean the debris on the filter screen 31, a cleaning device is provided inside the PVC water pipe 1. The cleaning device includes a scraping frame 62, and the rotation of the scraping frame 62 cleans the debris on the filter screen 31.

[0035] To drive the rotating rod 41 to rotate, the cleaning device further includes a motor 4.

The motor 4 is fixedly installed with the PVC water pipe 1. Fixing it, the motor 4 drives the rotating rod 41 to rotate so as to drive the driving bevel gear 7 fixedly installed with the rotating rod 41 to rotate.

[0036] To drive the rotation of the threaded rod 51, an electromagnet 5 is rotatably connected to the outer surface of the rotating rod 41. The inner wall of the groove of the electromagnet 5 is magnetically connected to the outer surface of the rotating rod 41 through an adsorbent. A threaded rod 51 is fixedly installed on the outer surface of the electromagnet 5. While the rotating rod 41 is rotatably connected to the electromagnet 5, it is magnetically connected through the adsorbent. When the electromagnet 5 is energized, the rotating rod 41 drives the electromagnet 5 to rotate, and at the same time drives the threaded rod 51 fixedly installed on the electromagnet 5 to rotate, so as to drive the lifting of the sleeve rod 61 through the sleeve 6.

[0037] To drive the lifting of the sleeve rod 61, a sleeve 6 is threadedly connected to the outer surface of the threaded rod 51. A sleeve rod 61 is rotatably connected to the outer surface of the sleeve 6. The outer surface of the sleeve rod 61 is rotatably connected to the outer surface of the scraping frame 62. A rotating bevel gear 63 is fixedly installed on the outer surface of the scraping frame 62. The threaded rod 51 is threadedly connected to the sleeve 6, driving it to rotate and lift. Through the rotational connection between the sleeve 6 and the sleeve rod 61, the sleeve rod 61 only moves up and down, thereby driving the scraping frame 62 rotatably connected to the sleeve rod 61 to move up and down. The scraping frame 62 is fixedly installed with the rotating bevel gear 63, driving it to move up and down. When it descends to a certain position, it meshes with the driving bevel gear 7, driving the scraping frame 62 to rotate and cleaning the filter net 31.

[0038] To clean the filter net 31, the outer surface of the scraping frame 62 is in contact with the outer surface of the filter net 31. A driving bevel gear 7 is fixedly installed on the outer surface of the rotating rod 41. The driving bevel gear 7 meshes with the rotating bevel gear 63. The scraping frame 62 is in contact with the filter net 31, scraping off the debris on its surface. The rotating rod 41 drives the driving bevel gear 7 to rotate. When the sleeve rod 61 drives the scraping frame 62 to descend to a certain position, the rotating bevel gear 63 fixedly installed on the scraping frame 62 meshes with the driving bevel gear 7, driving the scraping frame 62 to rotate and cleaning the filter net 31.

[0039] By setting up the cleaning device to clean the debris on the filter net 31, the motor 4 drives the rotating rod 41 to rotate. The rotating rod 41 drives the driving bevel gear 7 to rotate. While the rotating rod 41 is rotatably connected to the electromagnet 5, it is magnetically connected through the adsorbent. When the electromagnet 5 is energized, the rotating rod 41 drives the electromagnet 5 to rotate, and at the same time drives the threaded rod 51 fixedly installed on the electromagnet 5 to rotate. The threaded rod 51 is threadedly connected to the sleeve 6, driving it to rotate and lift. Through the rotational connection between the sleeve 6 and the sleeve rod 61, the sleeve rod 61 only moves up and down, thereby driving the scraping frame 62 rotatably connected to the sleeve rod 61 to move up and down. The scraping frame 62 is fixedly installed with the rotating bevel gear 63, driving it to move up and down. When it descends to a certain position, it meshes with the driving bevel gear 7, driving the scraping frame 62 to rotate and cleaning the filter net 31, solving the technical problems that when using a PVC drain pipe, manually pressing the scraper to vertically scrape off the debris has a low cleaning efficiency, may cause dirt residue, and during the vertical scraping process, the dirt may be compacted or difficult to completely remove.

[0040] Working principle: During the use of the PVC water pipe 1, sewage enters from the top of the PVC water pipe 1 and flows out from one side at the bottom. The filter screen 31 intercepts impurities in the sewage. When the user observes through the transparent observation window 32 that the filter screen 31 needs to be cleaned, the motor 4 is started to drive the rotating rod 41 to rotate, driving the driving bevel gear 7 fixedly installed with the rotating rod 41 to rotate. At the same time, the electromagnet 5 is energized to drive the threaded rod 51 to rotate, causing the sleeve 6 screwed to the screw rod to rotate and lift, so that the sleeve rod 61 rotatably connected to the sleeve 6 drives the scraping frame 62 fixedly connected to it to descend. When the rotating bevel gear 63 fixedly installed on the scraping frame 62 meshes with the driving bevel gear 7, the electromagnet 5 is powered off and the threaded rod 51 stops rotating. The rotating bevel gear 63 rotates to drive the scraping frame 62 to rotate, cleaning the debris on the filter screen 31. The debris falls into the sewage discharge pipe 2, and the liquid level sensor 3 monitors the accumulation of these debris in real time. When the debris accumulates to a certain extent, the valve is opened to allow the debris to flow out through the sewage discharge pipe 2.
