Description

Technical Field

[0001] This application relates to the field of drainage pipe maintenance equipment, and in particular to a drainage pipe anti-clogging and dredging device. Background Technology

[0002] Drainage pipes are a crucial component of urban infrastructure, responsible for discharging rainwater and sewage. Their smooth operation directly impacts the city's normal functioning and residents' daily lives. However, over time, drainage pipes easily accumulate silt and debris such as plastic bags, branches, and construction waste, leading to blockages and subsequent problems like flooding and sewage overflows. This not only affects the urban environment but can also damage the pipe structure and increase maintenance costs.

[0003] Currently, existing drainage pipe dredging devices are mainly divided into two categories: manual dredging and mechanical dredging. Manual dredging is inefficient, labor-intensive, and poses safety hazards, especially unsuitable for deeply buried pipes and large-diameter pipes. While mechanical dredging devices improve dredging efficiency to some extent, they still have many shortcomings: First, dredging is incomplete; most devices can only remove large pieces of debris inside the pipe and cannot effectively remove silt adhering to the inner wall of the pipe, easily leading to secondary blockages. Second, they have poor adaptability, making it difficult to adapt to drainage pipes of different diameters and lacking versatility. Third, they cause significant damage to the inner wall of the pipe; the scraping parts of some dredging devices are quite hard, easily scratching the inner wall of the pipe during the dredging process and shortening the pipe's service life. Fourth, they separate anti-blockage and dredging functions; most devices only have dredging functions and cannot intercept debris in advance to prevent blockages, only performing passive dredging after the pipe is blocked, resulting in poor maintenance. Therefore, there is an urgent need for a drainage pipe anti-blockage dredging device to solve the above problems. Summary of the Invention

The support mechanism includes a mounting base, movable wheels, and a drive assembly. The movable wheels are symmetrically arranged on both sides of the mounting base. The drive assembly is connected to the movable wheels and drives them to rotate, enabling the device to move within the drainage pipe. The adjustment mechanism is fixedly mounted on the mounting base. The anti-clogging mechanism and the sludge-removing mechanism are respectively connected to both ends of the adjustment mechanism, which is used to adjust the radial extension and retraction of the anti-clogging mechanism and the sludge-removing mechanism.

[0009] Optionally, the support mechanism further includes a buffer assembly, which includes a buffer spring and a buffer plate. One end of the buffer spring is connected to the mounting base, and the other end is connected to the buffer plate. The buffer plate is connected to the mounting bracket of the moving wheel to mitigate the impact force on the device during movement.

[0015] The following provides a further detailed description of this application.

[0016] This application discloses a drainage pipe anti-clogging and dredging device.

[0017] A drainage pipe anti-clogging and sludge removal device includes a support mechanism, an adjustment mechanism, an anti-clogging mechanism, a sludge removal mechanism, and a control mechanism. The support mechanism is used to achieve stable support and movement of the device within the drainage pipe. The adjustment mechanism is used to adjust the radial positions of the anti-clogging mechanism and the sludge removal mechanism to adapt to pipes of different diameters. The anti-clogging mechanism is used to intercept and crush debris and guide water flow. The sludge removal mechanism is used to scrape off and discharge sludge from the inner wall of the pipe. The control mechanism is used to control the coordinated operation of each mechanism to achieve automated anti-clogging and sludge removal.

[0018] The support mechanism includes a mounting base, casters, and a drive assembly. Two casters are symmetrically arranged on each side of the mounting base to improve the stability of the device's movement. The drive assembly uses a geared motor, which is connected to the casters via gear transmission. This allows the casters to rotate slowly, ensuring smooth movement of the device within the drainage pipe and preventing damage from collisions caused by excessive speed. The support mechanism also includes a buffer assembly consisting of a buffer spring and a buffer plate. One end of the buffer spring is welded to the mounting base, and the other end is welded to the buffer plate. The buffer plate is bolted to the mounting bracket of the casters. When the device encounters bumps or collisions while moving within the pipe, the buffer spring can elastically deform to absorb the impact and prevent damage to the casters and mounting base. The casters have anti-slip textures and are made of wear-resistant and corrosion-resistant polyurethane material. The mounting base is made of 304 stainless steel with an epoxy anti-corrosion coating, enabling it to adapt to the humid and corrosive environment inside the pipe and extending the device's service life.

[0019] The adjustment mechanism is fixedly installed in the middle of the mounting base. The adjustment mechanism includes an adjustment cylinder, a telescopic rod, and a mounting plate. The adjustment cylinder is fixed to the mounting base with bolts. One end of the telescopic rod is threaded to the output end of the adjustment cylinder, and the other end is welded to the mounting plate. The anti-blocking mechanism and the sludge removal mechanism are respectively fixed to the two mounting plates with bolts. The adjustment cylinder is equipped with a displacement sensor, which is a pull rod type displacement sensor and electrically connected to the control mechanism. It can detect the extension and retraction of the telescopic rod in real time and feed it back to the control mechanism. The operator can accurately adjust the extension and retraction length of the telescopic rod through the control mechanism, thereby adjusting the radial position of the anti-blocking mechanism and the sludge removal mechanism. It is suitable for drainage pipes with a diameter of 500mm-2000mm, with a wide range of applications.

[0020] The anti-clogging mechanism is located at the inlet of the device (near the direction of water flow) and includes an interception net, a pulverizing component, and guide blades. The interception net has an arc-shaped structure, with its curvature adapted to the inner wall of the pipe, allowing it to conform to the pipe's inner wall. The interception net is made of stainless steel woven mesh with a mesh diameter of 10mm-20mm, used to intercept large pieces of debris (such as branches, plastic bags, construction waste, etc.) in the pipe, preventing debris accumulation and blockage. The pulverizing component is located inside the interception net and includes a pulverizing motor, a pulverizing shaft, and pulverizing blades. The pulverizing motor is fixed to the mounting plate with bolts. One end of the pulverizing shaft is connected to the output end of the pulverizing motor via a coupling, and the other end passes through the interception net and extends to the outside of the interception net. The pulverizing blades are evenly distributed on the pulverizing shaft and are made of high-speed steel with a tungsten carbide wear-resistant coating on the edges to improve wear resistance. In terms of wear resistance and service life, when the pulverizing motor starts, it drives the pulverizing shaft and pulverizing blades to rotate, pulverizing large pieces of debris intercepted by the interception net into fine particles, which are easy to be discharged with the water flow. The guide blades are symmetrically arranged on both sides of the pulverizing shaft. The guide blades have an arc structure and are adapted to the water flow direction. They can initially guide the water flow and the pulverized debris in the pipe, improving drainage efficiency. The anti-clogging mechanism also includes a liquid level sensor. The liquid level sensor is an immersion type liquid level sensor, which is fixed to the outside of the interception net by a bracket. It is used to detect the liquid level height in the pipe and feed it back to the control mechanism. When the liquid level height exceeds the preset threshold (such as 2 / 3 of the pipe diameter), it indicates that there may be a blockage risk in the pipe. The control mechanism will automatically control the pulverizing component to start and accelerate the movement speed of the drive component to quickly clear debris and guide the water flow, so as to achieve active anti-clogging.

[0021] The sludge removal mechanism is located at the rear end of the device (away from the water flow direction) and includes a scraper, a rotary motor, and a discharge pipe. The scraper has an arc-shaped adaptable structure, with its curvature matching the inner wall of the pipe, allowing for a tight fit. The inner side of the scraper has an arc-shaped groove for collecting the scraped sludge, while the outer side has an elastic scraper made of wear-resistant nitrile rubber with a thickness of 5mm-10mm, ensuring effective sludge removal while preventing damage to the pipe's inner wall. The rotary motor is fixed to the mounting plate via a bracket. The motor's output end is connected to the middle of the scraper via a coupling, driving the scraper to rotate slowly (10-20 r / min) to remove sludge adhering to the pipe's inner wall. The discharge pipe, made of corrosion-resistant PVC, passes through the mounting base and connects to the arc-shaped groove of the scraper. The other end of the discharge pipe is equipped with a negative pressure suction system. The sludge removal system includes a small negative pressure pump, which is fixed to the mounting base by a bracket and electrically connected to the control mechanism. When the negative pressure pump starts, it generates negative pressure, quickly sucking the sludge collected in the arc-shaped groove into the discharge pipe and then out of the pipeline. The discharge pipe can be connected to external sewage collection equipment to prevent sludge from polluting the environment. The sludge removal mechanism also includes a high-pressure spray component, which is fixed to the outside of the scraper plate. The high-pressure spray component includes spray heads and high-pressure water pipes. The spray heads are evenly distributed on the outer edge of the scraper plate, facing the inner wall of the pipe. The high-pressure water pipes pass through the mounting base and are connected to the spray heads. The other end of the high-pressure water pipes is connected to an external high-pressure water supply device. When the high-pressure spray component starts, the spray heads spray high-pressure water (pressure 0.5-1.0 MPa) onto the inner wall of the pipe, flushing away the stubborn sludge attached to the inner wall of the pipe. This, combined with the scraper plate, achieves sludge removal and further improves the sludge removal effect.

[0022] The control mechanism includes a controller, a wireless communication module, and a remote control terminal. The controller is a PLC controller, fixed to the mounting base by a bracket. The controller contains a PLC control unit that receives signals from displacement sensors, liquid level sensors, and the positioning mechanism, and outputs control commands to control the start, stop, and parameter adjustment of the drive components, adjustment mechanism, crushing component, rotary motor, negative pressure suction component, and high-pressure spray component. The wireless communication module is a 4G / 5G dual-mode communication module, electrically connected to the controller, enabling signal interaction between the controller and the remote control terminal. The remote control terminal is a tablet or laptop computer with built-in dedicated control software. Operators can monitor the device's operating status in real time (such as movement speed, dredging progress, liquid level, and the operating status of each mechanism) and remotely control the operating parameters of each mechanism, achieving remote automated operation without requiring personnel to enter the pipeline, thus reducing safety hazards.

[0023] The device also includes a positioning mechanism, which consists of a GPS positioning module and a distance sensor. Both the GPS positioning module and the distance sensor are fixed on the mounting base by a bracket and electrically connected to the control mechanism. The GPS positioning module is used to detect the geographical location of the device in the pipeline in real time, and the distance sensor is a laser distance sensor used to detect the movement distance of the device. The two work together to help staff keep track of the dredging progress, accurately locate the blockage, and improve maintenance efficiency.

[0024] The implementation principle of the drainage pipe anti-blocking and sludge removal device in this application embodiment is as follows: the staff puts the device into the drainage pipe to be sludged, sends a control command through the remote control terminal, the controller controls the adjustment mechanism to start, the adjustment cylinder drives the telescopic rod to extend and retract, adjusts the radial position of the anti-blocking mechanism and the sludge removal mechanism, so that the elastic scraper of the interception net and the sludge scraper is in close contact with the inner wall of the pipe, and the displacement sensor feeds back the extension and retraction amount to the control mechanism to ensure that it is adapted to the pipe diameter.

[0025] After the device is started, the drive component drives the moving wheels to rotate, causing the device to move slowly along the pipeline. The anti-blocking mechanism's interception net intercepts large pieces of debris in the pipeline, and the liquid level sensor monitors the liquid level in the pipeline in real time. When the liquid level is normal, the crushing component is in standby mode, and the guide blades guide the water flow and debris. When the liquid level exceeds the preset threshold, the controller controls the crushing motor to start, driving the crushing shaft and crushing blades to rotate, crushing the intercepted large pieces of debris. The crushed debris is discharged with the water flow. At the same time, the controller controls the drive component to increase its moving speed, quickly clearing the debris in the pipeline and alleviating the risk of blockage.

[0026] During the movement of the device, the controller starts the rotary motor, which drives the scraper to rotate slowly. The elastic scraper removes the sludge adhering to the inner wall of the pipe, and the sludge falls into the arc-shaped groove on the inner side of the scraper. At the same time, the high-pressure spray component starts, and the spray head sprays high-pressure water into the inner wall of the pipe to flush away the stubborn sludge, which, together with the scraper, improves the sludge removal effect. The negative pressure suction component starts, generating negative pressure to suck the sludge in the arc-shaped groove into the discharge pipe, discharge it from the pipe, and collect it to the external sewage collection equipment.

[0027] Staff can monitor the device's working status in real time through a remote control terminal. The GPS positioning module and distance sensor provide feedback on the device's position and movement distance. Staff can adjust parameters such as the device's movement speed, the rotation speed of the scraper blades, and the water pressure of the high-pressure spray components according to the dredging progress. When the dredging operation is completed, staff send a stop command through the remote control terminal, all mechanisms stop working, and the device is removed from the pipeline, completing the dredging operation.

[0028] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
