Description

Technical Field

[0001] This utility model relates to the field of building water supply and drainage pipe cleaning technology, specifically to a pipe cleaning device for building water supply and drainage. Background Technology

[0002] Water supply and drainage pipelines refer to the system of pipes and their ancillary facilities that collect and discharge sewage, wastewater, and rainwater; including main pipes, branch pipes, and pipes leading to treatment plants. Regardless of whether they are built on streets or elsewhere, any pipe that serves a drainage function should be counted as a drainage pipeline. Currently, existing drainage pipes accumulate silt and other debris on their inner walls when discharging sewage, and are generally cleaned regularly to ensure smooth drainage. Patent CN215236516U discloses a pipe cleaning device for building water supply and drainage, including a rotating rod that passes through a telescopic cylinder. Two sets of sliding sleeves are fitted onto the telescopic cylinder, each set of which is equipped with multiple sets of telescopic components evenly distributed around its perimeter. The telescopic components on both sets of sliding sleeves are connected to cleaning components. Limiting components are provided on both sets of sliding sleeves. A connector is located at the top of the rotating rod, engaging a mounting groove on the connecting cylinder, which is mounted on a motor. This device, through the design of a sliding sleeve and telescopic components, solves the problem of existing technologies being unable to clean pipes of different diameters; the cleaning components also address the issue of low cleaning efficiency in existing technologies. However, current pipe cleaning devices used for building water supply and drainage can only clean a small section of the pipe at the end, failing to clean deeper sections, leading to an increased likelihood of blockages as drainage time increases. Therefore, there is an urgent need to develop a pipe cleaning device for building water supply and drainage. Utility Model Content

[0003] The purpose of this invention is to provide a pipe cleaning device for building water supply and drainage, which solves the problem that it is impossible to clean the deeper parts of the drainage pipe, which increases the probability of blockage inside the drainage pipe as the discharge time increases.

[0004] The technical solution of this utility model is as follows: a pipe cleaning device for building water supply and drainage, including a power component, a scraping component is provided on one outer wall of the power component, the power component includes a housing, a retainer is installed inside the housing, a motor with its output end connected to the scraping component is installed inside one side of the retainer, a shell that can be elastically raised and lowered is slidably connected to the upper and lower sides of the retainer, a connecting belt is installed between the shell and the housing, and mounting shells are provided on both sides of the inner side of the shell, and a traveling wheel that is driven to rotate by a drive mechanism and partially protrudes from the shell is installed inside the mounting shell.

[0005] Furthermore, the upper and lower outer walls of the cassette are each equipped with slide rods arranged at equal intervals. Springs are sleeved on the outside of the slide rods, and the two ends of the springs are fixedly connected to the cassette and the corresponding housing, respectively.

[0006] Furthermore, the drive mechanism includes a second motor mounted on the outer wall of the mounting housing, and a traveling wheel is rotatably mounted inside the mounting housing via bearings. A synchronous pulley is mounted on the output shaft of the second motor and one end of the traveling wheel, and a synchronous belt is wound between the two synchronous pulleys.

Two latches are installed on the outer walls of both sides of the lower box shell near the top. Two buckles are installed on the outer walls of both sides of the upper box shell near the bottom. One end of the latch is snapped onto the buckle.

[0008] Furthermore, a pump body is installed inside the other side of the casing. The water inlet of the pump body extends out from the other side of the casing and is connected to a connecting pipe. The water outlet of the pump body extends out from the other side of the casing and is connected to spray pipes that are evenly spaced and arranged in a ring structure.

[0009] Furthermore, a controller is installed inside the casing, and the controller is electrically connected to the pump body and the motor via wires.

[0010] Furthermore, a signal module and a GPS module are respectively installed on the bottom inner wall of one of the housings, and a battery is installed on the top inner wall of the other housing, and the battery is electrically connected to the signal module and the GPS module respectively through wires.

[0013] Furthermore, the connecting shaft has threaded holes spaced at equal intervals along its length, and the connecting cylinder is threadedly connected to the threaded holes; a mounting spring is installed between one end of the connecting rod and the inner wall of one side of the connecting cylinder.

[0014] Compared with the prior art, the present invention has the following advantages:

[0015] 1. The power component and the scraping component of this device work together to form a cleaning system that can clean deeper parts of the drainage pipe, reducing the chance of blockage in deeper parts of the drainage pipe due to lack of cleaning for a long time. This solves the problem that existing pipe cleaning devices can only clean one end of the drainage pipe and cannot clean deeper parts of the drainage pipe, which leads to an increased chance of blockage inside the drainage pipe as the discharge time increases.

The device's housing is a modular structure consisting of an upper shell, lower shell, latches, and buckles. The latches and buckles reduce the difficulty of disassembling and assembling the housing during maintenance, facilitating quick disassembly of the device. Attached Figure Description

[0023] To make the above-mentioned features and advantages of this utility model more easily understood, specific embodiments are described below in conjunction with the accompanying drawings, but this utility model is not limited thereto.

[0024] refer to Figures 1 to 5

[0025] A pipe cleaning device for building water supply and drainage includes a power component 1. A scraping component 2 is installed on one outer wall of the power component 1. The power component 1 includes a housing 3. A retaining housing 14 is bolted to the inside of the housing 3. A motor 9 is bolted to the inside of one side of the retaining housing 14. The output end of the motor 9 is connected to the scraping component 2 via a key. The motor 9 is a 57mm DC brushless motor that can move the scraping component 2. A flexible, adjustable housing 5 is slidably connected to the upper and lower sides of the retaining housing 14, making the structure formed by the housing 5 and the housing 3 adjustable, allowing the power component 1 to be placed inside drainage pipes of different specifications. A connecting strap 4 is bolted between the housing 5 and the housing 3. Mounting housings 6 are bolted to both sides of the inside of the housing 5. A traveling wheel 7, partially exposed and driven by a drive mechanism, is mounted inside the mounting housing 6 via bearings. For example, the upper part of the upper walking wheel 7 protrudes from the housing 5, and the lower part of the lower walking wheel 7 protrudes from the housing 5. The walking wheel 7 contacts the inner wall of the pipe, thus propelling the device forward or backward.

[0026] In this embodiment, the end of the housing 5 that mates with the box 3 is provided with an outwardly extending flange. The connecting strap 4 is bolted to the flange. The flange is rectangular in shape, and the connecting strap 4 can be made of rubber. This ensures that there are no gaps between the housing 5 and the box 3, and even when the housing is contracted, it prevents water from entering the power assembly 1 during cleaning. Furthermore, the inner and outer sides of the connecting strap 4 can also be connected to the box 3 and the housing 5 respectively. The connecting strap is an elastic band.

[0027] In this embodiment, to achieve the elastic lifting and lowering of the housing 5, slide rods 22 with equal spacing are bolted to the upper and lower outer walls of the retaining shell 14. Springs 23 are sleeved around the slide rods 22, and both ends of the springs 23 are fixedly connected to the retaining shell 14 and the corresponding housing 5 by bolts, thereby achieving the elastic lifting and lowering of the housing 5. Specifically, slide rods 22 can be evenly distributed along the length of the retaining shell 14 between the upper and lower outer walls of the retaining shell 14 and the inner walls on both sides of the housing 3; alternatively, slide rods 22 can be evenly distributed only on both sides of the upper and lower outer walls of the retaining shell 14.

[0028] In this embodiment, the drive mechanism includes a second motor 16 bolted to the outer wall of the mounting housing 6. Specifically, the upper motor 16 is mounted at the bottom of the upper mounting housing, and the lower motor 16 is mounted at the top of the lower mounting housing. A synchronous pulley 8 is mounted on one end of the output shaft of the second motor 16 and the shaft of the traveling wheel 7 via a flat key. A synchronous belt 10 is wound between the two synchronous pulleys 8, facilitating simultaneous movement of the two pulleys 8, thus allowing the traveling wheel 7 to follow the movement of the second motor 16. The traveling wheel 7 is similar to a gear, and the second motor 16 is a 57mm brushless DC motor.

[0029] In this embodiment, the housing 3 includes a lower housing 33 and an upper housing 35 with a rectangular frame structure. A sealing gasket 34 is snapped between the top of the lower housing 33 and the bottom of the upper housing 3. Two latches 36 are bolted to the outer walls of both sides of the lower housing 33 near the top. Two buckles 37 are bolted to the outer walls of both sides of the upper housing 35 near the bottom. One end of each latch 36 is snapped onto a buckle 37. The structure consisting of latches 36 and buckles 37 reduces the difficulty of disassembling and assembling the housing 3, allowing for quick disassembly of the equipment during maintenance.

[0030] In this embodiment, a pump body 17 is bolted to the other side of the housing 14. The water inlet of the pump body 17 extends through the other side of the housing 3 and is bolted to a connecting pipe 18, which is a water pipe in the prior art. The water outlet of the pump body 17 extends through the other side of the housing 3 and is connected to a spray pipe 20 with equally spaced ring-shaped structures. The pump body 17 is a small water pump, which facilitates the pumping of water from the water storage device into the spray pipe 20. One end of the spray pipe 20 has micro-holes, which facilitates the spraying of water pumped by the pump body 17 onto the inner wall of the pipe, thereby achieving the flushing of the inner wall of the pipe.

[0031] In this embodiment, a signal module 12 and a GPS module 13 are respectively installed on the inner bottom wall of one of the housings 5. The signal module 12 can be a 5G receiver, enabling the device to be connected to a remote control device; the GPS module 13 is a GPS sensor, enabling real-time positioning of the device. A battery 11 is installed on the inner top wall of the other housing 5, and the battery 11 is electrically connected to the signal module 12 and the GPS module 13 via wires. Simultaneously, the battery 11 also provides power to the first motor 9, the second motor 16, and the controller 15 via wires, and a voltage regulating component can be installed to meet the voltage requirements of each electrical component.

[0032] In this embodiment, a controller 15 is bolted to the inside of the housing 14. The controller 15 is electrically connected to the pump body 17 and the motor 9 via wires. The controller 15 is an existing PLC controller with a computer chip, which can receive information transmitted by the signal module 12 to control the operation of the device.

[0033] In this embodiment, in order to limit the retraction action of the housing 5, support columns 21 are welded to both sides of the upper and lower outer walls of the housing 14 so that the support columns 21 abut against the mounting housing 6 after the housing 5 retracts to a certain position, which helps to prevent the housing 5 from being damaged by excessive pressure between the housing 14 and the battery 11 when the housing 5 is squeezed.

[0034] In this embodiment, two buckles 19 are installed on the outer wall of the other side of the box 3 to facilitate the traction rope to be tied to the case 14.

[0035] In this embodiment, the scraping assembly 2 includes a connecting shaft 24 mounted on the output shaft of motor 9 via a flat key. Several connecting cylinders 26 are installed at equal intervals along the length of the connecting shaft 24 on the front and rear outer walls of the connecting shaft 25. One end of each connecting cylinder 26 is inserted into a connecting rod 27 that is elastically connected to it. A base plate 28 is welded to one end of each connecting rod 27, and a scraping component is mounted on the base plate 28. The connecting shaft 24 can rotate under the action of motor 9, thereby rotating the structure composed of the scraping component and the like, thus cleaning the inner wall of the drainage pipe.

[0036] Specifically, the scraping components consist of: sponges 30 adhered to one outer wall of each of the two substrates 28, and brush plates 29 installed on one outer wall of each of the two substrates 28. The sponges 30 and brush plates 29 can wipe the inner wall scraped by the scraper 31, removing stains from the inner wall and preventing the stains from sticking to the inner wall of the drain pipe. Additionally, scrapers 31, evenly spaced and arranged in a ring structure, are welded to one outer wall of each of the other two substrates 28. As the substrates 28 rotate, the scrapers 31 can scrape the inner wall of the drain pipe, removing stubborn stains.

[0037] In this embodiment, the sponge 30, brush plate 29 and scraper 31 are arranged sequentially from one end of the connecting shaft 24 near the box 3 to the cantilever end of the connecting shaft 24, and are arranged in pairs on the front and back sides of the same part of the connecting shaft 24.

[0038] In this embodiment, the connecting shaft 24 has threaded holes 25 spaced evenly along its length. The connecting cylinder 26 is welded with threaded posts and threadedly connected to the threaded holes 25, thus facilitating the installation of the connecting cylinder 26 on the connecting shaft 24. A mounting spring 32 is bolted between one end of the connecting rod 27 and the inner wall of one side of the connecting cylinder 26. The spring 32 allows the structure formed by the connecting rod 27 and the connecting cylinder 26 to be adjustable, enabling the sponge 30 on the substrate 28 to contact the inner walls of pipes of different specifications.

[0039] Working principle: When using this device, the prepared traction rope can be tied to the buckle 19, and then the flanged end of the connecting pipe 18 can be bolted to the water inlet end of the pump body 17. The other end of the connecting pipe 18 can then be connected to the water storage device. Next, the scraping assembly 2 can be mounted on the output shaft of the motor 9 using bolts, flat keys, etc. Finally, the assembled device can be placed into the drain pipe. After the above preparation steps are completed, the device can be operated via a remote control. When the signal module 12 receives a signal, it transmits it to the controller 15. The controller 15 controls the four motors 16 to start, and through the two pulleys 8 cooperating with the corresponding traveling wheels 7 of the synchronous belt 10, the device moves along the inner wall of the drain pipe. While the device moves inside the drain pipe, the above steps can be repeated to send a command to the controller 15, causing the controller 15 to start the motor 9. This causes the connecting shaft 24 to rotate, carrying the structure consisting of the connecting cylinder 26, connecting rod 27, etc., and causing the base plate 28 to rotate, carrying the sponge 30, brush plate 29, and scraper 31 to clean the inner wall of the drain pipe. Then, with the movement of the power component 1, the device will thoroughly clean the inside of the drain pipe. During cleaning, the pump 17 will start, causing the connecting pipe 18 to pump water from the water storage device into the spray pipe 20. The spray pipe 20 will then spray high-pressure water to rinse the inner wall of the drain pipe. After cleaning, the above steps can be repeated to move the device towards one end of the drain pipe for easy removal. In case of insufficient power, the device can be pulled out using a traction rope, and then the valve can be opened to allow water to flow through the drain pipe, flushing out the impurities cleaned by the cleaning device.

Unless otherwise stated, the above terms have no special meaning.
