Description

Technical Field

[0001] The utility model relates to the technical field of drainage pipes, in particular to a drainage pipe that is easy to maintain. Background Art

[0002] Traditional cast iron drainage pipes are mainly made of cast iron materials. Their manufacturing process usually involves pouring liquid cast iron into a specific mold, and then forming pipe sections with certain specifications through processes such as cooling and demolding. This process has been widely used for a long time in the past because cast iron itself has high strength and can withstand a certain amount of pressure, making it suitable for transporting various fluids such as sewage and rainwater in the drainage system of buildings.

[0003] Common connection methods for drainage pipes include the socket-and-spigot joint. In this method, the spigot end of one pipe is inserted into the socket end of another. Sealing materials such as hemp and cement are then used to ensure a tight seal at the joint, preventing fluid leakage. Under the technical conditions of the time, this connection method met basic drainage needs and was relatively secure.

[0004] However, the current drainage pipes lack a convenient internal cleaning mechanism, making it difficult to effectively clean the inner wall of the pipes, which may cause dirt and debris to accumulate and affect drainage. There is also no convenient internal observation method, and it is impossible to intuitively understand the internal condition of the pipes during maintenance, which is not conducive to accurate problem detection. Maintenance operations often require cutting off the medium flow, which will interrupt the drainage operation and bring inconvenience and impact to related links. In view of this, we have proposed an easy-to-maintain drainage pipe. Utility Model Content

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0029] See also Figure 1 - Figure 6 , the utility model provides a technical solution:

[0030] A drainage pipe that is easy to maintain includes a liquid inlet pipe 1, which is fixedly installed with one end of a main pipe 2 through a fixing piece 6. The other end of the main pipe 2 is fixedly connected to one end of a T-shaped pipe 3 through a fixing piece 6. The other end of the T-shaped pipe 3 is fixedly installed with one end of a secondary pipe 4 through a fixing piece 6. The other end of the secondary pipe 4 is fixedly installed with a liquid outlet pipe 5 through a fixing piece 6. In addition, three groups of fixing pieces 6 are provided, and a single group of fixing pieces 6 includes two groups of flange rings and multiple groups of bolts and nuts, thereby making the pipe body more secure and convenient for disassembly and maintenance.

[0031] In one embodiment of the present utility model, a maintenance assembly 7 is provided on the T-shaped tube 3. The maintenance assembly 7 includes a conical cover 71. The conical cover 71 is fixedly installed on the top of the T-shaped tube 3 through a fixing member 6. A servo motor 72 is clamped on the top of the conical cover 71. A rotating drum 73 is fixedly installed on the outer side of the rotating shaft at the bottom end of the servo motor 72. The outer side of the rotating drum 73 is fixedly installed on the inner side of the sealed bearing 710. The outer side of the sealed bearing 710 is fixedly installed on the inner side wall of the T-shaped tube 3. A round sleeve 74 is fixedly installed on the outer side of the round sleeve 74. A support rod 75 is fixedly installed on the outer side of the support rod 75. A scraper 76 is fixedly installed on the outer side of the support rod 75. The outer side of the scraper 76 slides in contact with the curved inner wall of the T-shaped tube 3. In addition, two groups of support rods 75 and scrapers 76 are provided, so that the cleaning effect is better. A cable 77 is provided on the inner side of the top of the T-shaped tube 3, and a miniature camera 78 is provided on the cable 77. In addition, the rotating drum 73 is made of transparent material, so that the miniature camera 78 can smoothly take pictures. A through groove 79 is provided on the curved side wall of the top of the rotating drum 73. In addition, sealing rings 711 are provided between the main tube 2 and the T-shaped tube 3 and between the T-shaped tube 3 and the secondary tube 4. The sealing rings 711 are made of rubber material, so that the sealing performance is better.

[0032] In one embodiment of the present utility model, an auxiliary component 8 is provided on the outside of the T-shaped tube 3, and the auxiliary component 8 includes a main valve 81. The main valve 81 is provided on the liquid inlet pipe 1 and the liquid outlet pipe 5. A bent pipe 82 is fixedly installed between the liquid inlet pipe 1 and the liquid outlet pipe 5. In addition, a secondary valve 83 is provided on the bent pipe 82.

[0033] Working principle: When the servo motor 72 installed on the top of the conical cover 71 and fixedly connected to the rotating drum 73 on the outside of the rotating shaft at its bottom is started, the servo motor 72 drives the rotating drum 73 to rotate, and the circular sleeve 74 fixedly installed on the outside of the rotating drum 73 will rotate together with the rotating drum 73, and the support rod 75 fixed on the outside of the circular sleeve 74 will also rotate accordingly, thereby causing the scraper 76 fixed on the outside of the support rod 75 to rotate, and the outer side of the scraper 76 slides and fits against the curved inner wall of the T-shaped tube 3. Through the rotation of the scraper 76, the inner wall of the T-shaped tube 3 is cleaned, and since there are two groups of support rods 75 and scrapers 76, a better cleaning effect can be achieved.

[0034] When it is necessary to observe and maintain the internal situation of the pipeline body, first open the conical cover 71, and then use the cable 77 arranged on the inner side of the top of the T-shaped tube 3 to extend the micro camera 78 installed on the cable 77 into the interior of the rotating drum 73 through the through groove 79 opened on the arc-shaped side wall of the top of the rotating drum 73. Since the rotating drum 73 is made of transparent material, the micro camera 78 can smoothly take pictures, so that the internal situation of the pipeline body can be easily observed. At the same time, sealing rings 711 made of rubber material are provided between the main pipe 2 and the T-shaped tube 3 and between the T-shaped tube 3 and the secondary pipe 4, and the outer side of the rotating drum 73 is fixedly installed on the inner side of the sealing bearing 710, and the outer side of the sealing bearing 710 is fixedly installed on the inner side wall of the T-shaped tube 3. These sealing structures (sealing bearing 710 and sealing ring 711) can make the overall sealing effect of the pipeline better, so as to ensure the normal operation of the pipeline system during observation and other maintenance operations, and then the drainage pipeline body can be maintained more conveniently.

[0035] By controlling the opening and closing states of the main valve 81 provided on the liquid inlet pipe 1 and the liquid outlet pipe 5 and the secondary valve 83 installed on the elbow 82, the flow path of the medium can be controlled. Specifically, when it is necessary to maintain the pipeline body without cutting off the medium, the main valve 81 can be closed and the secondary valve 83 can be opened to allow the medium to pass through the elbow 82, thereby achieving the effect of being more convenient for maintaining the pipeline body without cutting off the medium. For example, when performing maintenance operations on a certain section of the pipeline, the valve state can be adjusted according to the actual situation to allow the medium to continue to flow through other unmaintained pipeline sections, thereby avoiding cutting off the medium flow due to maintenance and affecting the normal operation of the entire drainage system.

[0036] The above generally describes the present invention in detail. However, it is obvious to those skilled in the art that modifications or improvements may be made to the present invention. Therefore, modifications or improvements that do not depart from the spirit of the present invention are within the scope of protection of the present invention.
