Description

Technical Field

[0001] This application relates to the field of pipe cleaning technology, specifically a house pipe cleaning device. Background Technology

[0002] Clogged pipes are a common problem in municipal and construction industries. Traditional cleaning methods have significant drawbacks: mechanical cleaning tools are only suitable for short, straight pipes and are prone to getting stuck in S-bends and U-bends, and metal drill bits can easily scratch the pipe walls; high-pressure water flushing relies on external water sources and has limited effectiveness against hard scale, and sewage overflow can easily pollute the environment; traditional devices lack sensory feedback, making it impossible to accurately locate the blockage or assess the cleaning effect, often leading to repetitive work and low efficiency.

[0003] While existing patents cover pipe cleaning structures, they do not simultaneously address the issues of diameter adaptation, visual monitoring, and intelligent control. Therefore, there is an urgent need for a pipe cleaning device that features adaptive diameter changes, efficient cleaning, and intelligent feedback. Utility Model Content

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this application provides a house pipe cleaning device with a reasonable structure. By incorporating a flexible conduit assembly, an expandable cleaning head assembly, a power drive system, and an intelligent control module, it specifically solves the deficiencies of existing technologies in terms of adaptability, efficiency, and intelligence. The coordinated functions and parameter linkage of each component enable the device to achieve precise adaptation, efficient operation, and safe and controllable house pipe cleaning.

[0006] (II) Technical Solution

[0007] To achieve the above objectives, this application provides the following technical solution: a house pipe cleaning device, comprising a flexible conduit assembly, an expandable cleaning head assembly, a power drive system, and an intelligent control module; the flexible conduit assembly is a multi-layered composite tubular structure, internally integrating a central working channel, a photoelectric signal channel, and a drive control channel; the expandable cleaning head assembly is located at the front end of the flexible conduit assembly, including an elastic arc plate connected to a central shaft via a ball joint and a coaxially sleeved spiral pusher, as well as an endoscope assembly connected to the top of the spiral pusher; the power drive system includes a stepper motor for controlling the expansion of the elastic arc plate and a drive motor for driving the spiral pusher; the intelligent control module integrates a visual interface, an expansion knob, a speed slider, a pressure sensor, and a temperature sensor, and communicates with the expandable cleaning head assembly through the photoelectric signal channel and the drive control channel.

[0008] Preferably, the flexible catheter assembly comprises, from the inside out, an inner protective layer, a reinforcing layer, and an outer wear-resistant layer; the inner protective layer is a medical-grade silicone tube; the reinforcing layer is a stainless steel wire braided mesh; and the outer wear-resistant layer is a polyurethane elastomer.

[0009] Through the above technical solutions, medical-grade silicone tubing possesses excellent flexibility and elasticity, enabling it to adapt to bending and deformation of the tubing. It also provides a smooth inner wall, reducing frictional damage to the inner wall of the tubing. The stainless steel wire mesh provides strong radial support, preventing the catheter from collapsing or deforming under high pressure or bending, ensuring stable operation of the device in complex pipelines. It can withstand mechanical wear and pressure shocks during long-term use, extending the service life of the catheter. The polyurethane elastomer has extremely high wear resistance and anti-aging properties, resisting friction on the inner wall of the tubing and corrosion from the external environment, protecting the overall structure of the catheter.

[0010] Preferably, the elastic arc sheet is a titanium alloy arc sheet, and there are 4 pieces evenly distributed along the circumference; the ball joint includes a ball head and a ball socket, the ball head is fixed to the inner end of the elastic arc sheet, the ball socket is opened on the outer surface of the central shaft, and the ball head can rotate 0°-80° in the ball socket.

[0011] Through the above technical solution, the titanium alloy arc plate has the characteristics of high density and high strength, which can reduce the overall weight of the device and withstand the mechanical stress during the pipeline cleaning process, avoiding deformation or breakage. The four elastic arc plates are evenly distributed in the circumference, which can achieve symmetrical expansion and ensure that the cleaning head assembly fits evenly against the inner wall of the pipeline, avoiding local cleaning blind spots. The ball joint structure allows the elastic arc plate to rotate within the range of 0°-80°, adapting to pipelines of different diameters and shapes, especially curved or irregular pipelines.

[0012] Preferably, the spiral pusher includes variable pitch spiral blades fixedly mounted on its outer circumference, wherein the spacing between the variable pitch spiral blades is smaller at the front and larger at the rear.

[0013] Through the above technical solutions, the small spacing between the front blades provides greater gripping and pushing force during spiral propulsion, effectively pushing dirt, debris, or liquid in the pipe backward to avoid blockage. The large spacing between the rear blades reduces interference with the cleaned area and prevents dirt from being stirred up or accumulated again. The variable pitch design can automatically adjust the propulsion effect according to the density and state of dirt in the pipe.

[0014] Preferably, the pressure sensor is embedded in the bottom of the ball socket; the temperature sensor is attached to the inner surface of the outer wear-resistant layer.

[0015] Through the above technical solution, the pressure sensor is embedded in the bottom of the ball socket, which can directly detect the pressure of the elastic arc plate on the inner wall of the pipe during the expansion process, ensuring that the expansion force is within a safe range and avoiding pipe damage or device jamming due to excessive pressure. By feeding back pressure data, the intelligent control module can dynamically adjust the output of the stepper motor to achieve precise expansion control. The temperature sensor is attached to the inner surface of the outer wear-resistant layer, which can detect the temperature change of the device in real time during operation.

[0016] Preferably, a torque sensor is sleeved between the output shaft of the drive motor and the coupling.

[0017] Through the above technical solution, the torque sensor can detect the torque value of the drive motor output shaft in real time, reflecting the resistance encountered by the spiral pusher in the pipeline.

[0018] Preferably, the elastic arc sheet has an embedded nylon scraper and is driven by a stepper motor connected by a metal wire.

[0019] Through the above technical solution, the nylon scraper is embedded in the surface of the elastic arc plate, which can make close contact with the inner wall of the pipe during the expansion process. Through rotation or reciprocating motion, it can effectively scrape away stubborn dirt such as oil stains, rust, and scale. The stepper motor drives the elastic arc plate and scraper through metal wire, which can achieve high-precision position control and speed adjustment, ensuring the stability and repeatability of the cleaning action.

[0020] Preferably, the endoscope assembly includes a connecting rod fixedly installed at the top of the spiral pusher, the top of the connecting rod being tapered, and an endoscope being embedded inside the top of the rod.

[0021] With the above technical solution, the endoscope is embedded in the top of the connecting rod and can transmit images or videos of the inside of the pipe in real time, helping the operator to intuitively understand the cleaning effect and pipe condition. During the cleaning process, the operator can observe the images transmitted by the endoscope through a visual interface and adjust the cleaning strategy in a timely manner.

[0022] Compared with the prior art, this application provides a house pipe cleaning device, which has the following beneficial effects:

[0023] In operation, the operator first observes the pipeline image transmitted by the endoscope component through the visual interface of the intelligent control module to locate the blockage and determine its type. Then, adjusting the expansion knob activates a stepper motor that drives the reel to wind up the metal wire, pulling the elastic arc plate outwards around a ball joint, causing the nylon scraper along the outer edge of the arc plate to adhere to the inner wall of the pipeline. Next, adjusting the speed slider sets the speed of the spiral pusher, starting the drive motor and rotating the variable-pitch spiral blades. The denser pitch at the front breaks up the blockage, while the looser pitch at the rear pushes the debris. During the cleaning process, pressure, temperature, and torque sensors collect data in real time and feed it back to the control module, which automatically adjusts its operating status accordingly. After cleaning, adjusting the expansion knob reverses the stepper motor to release the metal wire, causing the elastic arc plate to contract, the device to exit the pipeline, and the control module generates a cleaning report recording key data.

[0031] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0032] Please see Figure 1-5 A house pipe cleaning device includes a flexible conduit assembly 3, an expandable cleaning head assembly 4, a power drive system 2, and an intelligent control module 1. The flexible conduit assembly 3 is a multi-layered composite tubular structure that enables passage through complex pipes. It integrates a central working channel 34, a photoelectric signal channel 35, and a drive control channel 36. The expandable cleaning head assembly 4 is located at the front end of the flexible conduit assembly 3 and includes an elastic arc plate 42 connected to a central axis via a ball joint 10, a coaxially sleeved spiral pusher 6, and an endoscope assembly 5 connected to the top of the spiral pusher 6. The power drive system 2 includes a stepper motor 21 that controls the expansion of the elastic arc plate 42 and a drive motor 22 that drives the spiral pusher 6. The intelligent control module 1 integrates a visual interface 11, an expansion knob 12, a speed slider 13, a pressure sensor 45, and a temperature sensor 46, and communicates with the expandable cleaning head assembly 4 through the photoelectric signal channel 35 and the drive control channel 36.

[0033] Furthermore, the flexible catheter assembly 3 consists of an inner protective layer 33, a reinforcing layer 32, and an outer wear-resistant layer 31, arranged from the inside out. The inner protective layer 33 is a medical-grade silicone tube; the reinforcing layer 32 is a stainless steel wire braided mesh; and the outer wear-resistant layer 31 is a polyurethane elastomer.

[0034] The advantages are that, firstly, the front end of the flexible catheter assembly 3 is inserted into the pipe inlet, and the operator observes the pipe image transmitted by the endoscope component 5 through the visualization interface 11 of the intelligent control module 1, locates the blockage location and determines the type of blockage. When the flexible catheter assembly 3 is working, the medical-grade silicone tube of the inner protective layer 33 can ensure the flexibility and biocompatibility when in contact with the pipe. The stainless steel wire braided mesh of the reinforcing layer 32 can effectively improve the compressive strength of the catheter to cope with complex pipe passage. The polyurethane elastomer of the outer wear-resistant layer 31 can enhance the wear resistance of the catheter exterior, ensuring that the flexible catheter assembly 3 can operate stably, durablely and flexibly in complex pipe environments.

[0035] Furthermore, the elastic arc plate 42 is a titanium alloy arc plate, and there are 4 pieces, which are evenly distributed in the circumference; the ball joint 10 includes a ball head and a ball socket, the ball head is fixed to the inner end of the elastic arc plate 42, the ball socket is opened on the outer surface of the central shaft, and the ball head can rotate 0°-80° in the ball socket;

[0036] The advantages are that the titanium alloy material has both high strength and lightweight, which can effectively fit different pipe diameters and withstand expansion pressure. The 0°-80° rotation design of the ball joint 10 allows the elastic arc plate 42 to adapt to the expansion of the pipe contour, so as to achieve uniform contact and efficient scraping of the cleaning head against the inner wall of the pipe, while ensuring the flexibility and stability of the mechanism movement.

[0037] Furthermore, the spiral pusher 6 includes variable pitch spiral blades 43 fixedly mounted on the outer circumferential surface, with the blade spacing of the variable pitch spiral blades 43 being smaller at the front and larger at the rear.

[0038] The advantage is that the speed of the screw pusher 6 is set by adjusting the speed slider 13, the drive motor 22 is started, and the power is transmitted to the central shaft through the coupling, driving the screw blades to rotate at high speed. The screw blades adopt a variable pitch design, with a smaller pitch at the front and a larger pitch at the rear. This design allows the screw pusher 6 to generate a larger crushing force at the front end to break up the blockage when it is working, while the wider pitch at the rear end can provide a greater pushing force to quickly push the broken blockage to the downstream of the pipeline.

[0039] Furthermore, the pressure sensor 45 is embedded in the bottom of the ball socket; the temperature sensor 46 is attached to the inner surface of the outer wear-resistant layer 31; and a torque sensor is sleeved between the output shaft of the drive motor 22 and the coupling.

[0040] The advantages are that during the cleaning process, the pressure sensor 45, temperature sensor 46, and torque sensor collect pressure, temperature, and torque data in real time and feed them back to the control module. The control module automatically adjusts the working state of the device according to the data to ensure that the cleaning work is carried out safely and efficiently. The pressure sensor 45 is embedded in the bottom of the ball socket of the ball joint 10 to detect the contact pressure between the elastic arc plate 42 and the pipe wall in real time, ensuring that the elastic arc plate 42 adheres to the pipe wall under appropriate pressure. The temperature sensor 46 is attached to the inner surface of the outer wear-resistant layer 31 to monitor the working temperature of the device. When the temperature is too high, the control module automatically reduces the motor power or stops operation to prevent the device from being damaged due to overheating. The torque sensor is sleeved between the output shaft of the drive motor 22 and the coupling to monitor the torque change when the screw pusher 6 rotates in real time. When the torque exceeds the set threshold, an alarm signal is sent to the control module. The data collected by the pressure sensor 45, temperature sensor 46, and torque sensor are transmitted to the control module. The control module analyzes and processes the data according to the preset program and algorithm, automatically adjusts the working parameters of the device, and realizes closed-loop control of the cleaning process.

[0041] Furthermore, a nylon scraper 41 is embedded in the elastic arc sheet 42 and is driven by a stepper motor 21 connected by a metal wire 44.

[0042] The advantage is that after the cleaning plan is determined by the endoscope assembly 5, the expansion knob 12 of the intelligent control module 1 sends a command to the stepper motor 21, and the stepper motor 21 drives the winding reel to wind up the metal wire 44.

[0043] Furthermore, the endoscope assembly 5 includes a connecting rod 51 fixedly mounted on the top of the spiral pusher 6. The top of the connecting rod 51 is tapered, and an endoscope 52 is embedded inside the top.

[0044] The advantage is that when the metal wire 44 is pulled by the reel, the tension is transmitted to the elastic arc plate 42 through the cold-pressed terminal at the outer end of the arc plate, causing it to rotate outward and expand with the ball joint 10 as the fulcrum. The nylon scraper 41, which is vulcanized and fixed on the outer edge of the arc plate, gradually contacts and adheres to the inner wall of the pipe during the expansion process, thus cleaning the pipe wall. After cleaning, the expansion knob 12 is adjusted to reverse the stepper motor 21, releasing the metal wire 44. The elastic arc plate 42 contracts, the device exits the pipe, the control module generates a cleaning report, records key data during the cleaning process, and at the same time, the endoscope 52 is protected by the connecting rod 51 of the endoscope assembly 5.

[0045] Although embodiments of this application have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the appended claims and their equivalents.
