Description

Technical Field

[0001] This utility model relates to the field of sewage treatment equipment technology, and in particular to a traveling sludge suction machine with anti-derailment function. Background Technology

[0002] In water treatment processes, sedimentation tanks (such as large horizontal flow sedimentation tanks, inclined tube sedimentation tanks, and high-density sedimentation tanks) are key facilities for achieving solid-liquid separation. The traveling sludge suction machine, as the core equipment for removing sludge from the bottom of the sedimentation tank, directly affects the effluent quality, effective volume, and process efficiency of the sedimentation tank. This equipment typically spans both sides of the tank, reciprocating along a track to drive the suction pipe or scraper to collect and discharge the settled sludge from the bottom of the tank.

[0003] However, existing traveling suction sludge machines face numerous problems affecting their safe and stable operation during long-term operation: I. Lack of Track Condition Monitoring: Due to long-term operation, foundation settlement, installation errors, or thermal expansion and contraction, the track is prone to height deviation or insufficient parallelism. Existing equipment lacks real-time and accurate monitoring methods, relying on manual visual observation or periodic level checks, making it difficult to detect minor track irregularities and creating potential derailment hazards.

[0004] II. Difficulty in Cleaning Track Debris: The high humidity in the sedimentation tank environment easily leads to the accumulation of dust, scale, algae, leaves, flocculent matter, and bottom mud on the tracks. This debris increases the running resistance of the crane wheels, resulting in increased motor load, higher energy consumption, and even causing the wheel flanges to "climb" or shift laterally off the track, ultimately leading to derailment. Traditional manual cleaning methods are inefficient, consume production time, and cannot solve the problem in real time.

[0005] 3. Key components are susceptible to damage from moisture: The sedimentation tank area is damp. During equipment cleaning and rainy or foggy weather, water and sewage can easily splash or seep into the walking motor, reducer, bearings and exposed electrical components (such as limit switches, sensors and control boxes), causing motor short circuits, bearing corrosion and jamming, sensor failures and electrical short circuits, which are the main causes of equipment failure.

[0006] IV. The consequences of derailment accidents are serious: Derailment will lead to shutdown, affect the water treatment process, and the accident handling time is long, difficult (often requiring crane intervention), and costly. It also poses safety risks and seriously threatens the stable operation of the water plant and the protection of water quality.

[0007] V. Limitations of existing solutions: Currently, solutions mainly rely on periodic inspections, manual cleaning, enhanced sealing, and post-incident repairs, lacking automated and real-time preventative solutions, and are particularly weak in automatic track cleaning and protection of critical components. Utility Model Content

[0008] The technical problem this utility model aims to solve is to overcome existing defects and provide a traveling sludge suction machine with anti-derailment function. Through the integrated design of monitoring, cleaning, and protection, the operational reliability of the traveling sludge suction machine is greatly improved, ensuring the continuous operation of the sedimentation tank and the stability of the effluent water quality. It has protective functions, which can extend the service life of components and reduce failures. It can clean debris on the track surface synchronously with the traveling sludge suction machine, reducing running resistance and jamming risk, reducing energy consumption, and eliminating the need for manual shutdown for cleaning. It can effectively prevent derailment accidents and effectively solve the problems in the background technology.

[0009] To achieve the aforementioned objective, this utility model adopts the following technical solution: A traveling-type sludge suction machine with anti-derailment function includes: The main body of the crane: It is set across the sedimentation tank; Two parallel tracks are laid on both sides of the sedimentation tank; Walking mechanism: includes drive wheels and driven wheels installed on both sides of the bottom of the traveling body, and both drive wheels and driven wheels are in contact with the track; Dual-sensor real-time monitoring system: It includes two ranging sensors, which are set to correspond to the left and right sides of the vehicle body; Follow-up cleaning device: It includes two sets of cleaning brushes, which are respectively set on the drive wheel and the driven wheel and fixed on the bracket of the traveling body. The cleaning brushes are set to contact the track surface. The protective system includes a protective cover and a waterproof and breathable valve. The protective cover covers and encloses the drive motor, gearbox, and distance sensor, and has a maintenance door on its surface. The waterproof and breathable valve is installed on the top or side of the protective cover. The output shaft of the drive motor is connected to the input shaft of the gearbox, and the output shaft of the gearbox is connected to the axle of the drive wheel. Audible and visual alarm: It is installed on the side of the vehicle body; It also includes a control box, which is installed on the top of the vehicle body. The ranging sensor and the audible and visual alarm are both electrically connected to the control box, which is electrically connected to an external power source.

[0010] Furthermore, the ranging sensor is either a laser ranging sensor or an ultrasonic ranging sensor, and its detection end contacts the external environment through a reserved transparent window or a sealed probe structure in the protective cover, while the main body is sealed and wrapped by the protective cover.

[0011] Furthermore, the protective cover is made of waterproof and corrosion-resistant material, and the mating surfaces with the drive motor, gearbox and ranging sensor are equipped with sealing gaskets, and the cable inlet is equipped with a waterproof connector.

[0012] Furthermore, the maintenance door is a hinged or detachable panel, and a sealing strip is provided at the junction with the protective cover.

[0013] Furthermore, the top of the protective cover has a sloping structure.

[0014] Furthermore, the cleaning brush is made of nylon bristles or stainless steel wire.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: This traveling-type sludge suction machine with anti-derailment function has the following advantages: 1. The dual-sensor real-time monitoring system uses symmetrically arranged distance sensors to capture changes in track smoothness in real time. After the data is analyzed by the control box, it can promptly issue warnings through audible and visual alarms to prevent derailment accidents.

[0016] 2. The cleaning brush of the follow-up cleaning device cleans the track surface debris synchronously with the operation of the train, reducing running resistance and jamming risk, reducing energy consumption, and eliminating the need for manual shutdown for cleaning.

[0017] 3. The protective cover is made of waterproof and corrosion-resistant materials and has a sealed structure. Combined with a waterproof and breathable valve and a sloping top, it effectively isolates the drive motor, gearbox and distance sensor from the humid environment, extends the life of the components and reduces failures.

[0018] 4. Through the integrated design of monitoring, cleaning and protection, the operational reliability of the traveling sludge suction machine is greatly improved, ensuring the continuous operation of the sedimentation tank and the stability of the effluent water quality.

Follow-up cleaning device: It includes two sets of cleaning brushes 4, which are respectively set on the drive wheel 8 and the driven wheel 5 and fixed on the bracket of the traveling body 1. The cleaning brushes 4 are in contact with the surface of the track 10 and clean the track 10 synchronously with the operation of the traveling body 1.
