DETAILED DESCRIPTION

[0026] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative labor fall within the scope of protection of the present application.

[0027] Please refer to Figures 1-8 The present application provides a technical solution: a pipeline dredging device for highway pipeline facility engineering, comprising a cleaning vehicle 1, which is a professional equipment for cleaning the road surface and drainage system of a highway (hereinafter referred to as a highway). The bottom area of the cleaning vehicle 1 is carefully designed and is provided with an efficient cleaning assembly. The cleaning assembly comprises two main parts: one is an upper cleaning assembly located above the cleaning vehicle, which is specially responsible for thoroughly cleaning the drainage pipelines on both sides of the highway, thereby ensuring the smoothness of the drainage system; the other is a lower cleaning assembly located below, which is specially used for efficiently cleaning the drainage channels of the highway road surface.

[0028] In addition, the upper part of the cleaning vehicle 1 is provided with a multi-chamber bin body structure. The system is composed of three independent and functionally distinct bin bodies, namely a first bin body 2, a second bin body 3 and a third bin body 4. The first bin body 2 is used for storing light impurities, the second bin body 3 is used for storing liquid, which can be used for cleaning the highway road surface, and the third bin body 4 is used for collecting the sludge on the highway road surface. This multi-bin system adopts an advanced modular design concept. Each bin body is a physically isolated independent unit, which together constitutes a hierarchical and clearly divided processing system. Through the coordinated work of the internal precise connecting pipelines, various functional components and intelligent control units, the system can efficiently realize the comprehensive cleaning of various types of pollutants such as accumulated water, dry garbage, wet garbage and sludge, and improve the overall efficiency and automation level of the cleaning operation.

[0029] Specifically, the top of the first bin body 2 is provided with a mechanical arm rod assembly specially used for dredging operation, which includes a base 5 firmly welded and structurally stable, which is fixed to the top of the bin body by high-strength bolts, and above which is assembled a mechanical arm rod 6 which can be flexibly rotated at multiple angles, and an elongated groove 7 is designed at a proper position of the mechanical arm rod 6, and a hose 8 with certain flexibility and wear resistance is embedded inside the groove 7, one end section of the hose 8 is fixed to the internal space of the first bin body 2 by a pipe clamp, and the other end extends to the external environment from the end of the mechanical arm rod 6 and can be adjusted in length by manual operation or connection of an automatic control system. This design enables the garbage inlet at the front end of the hose 8 to be flexibly close to or lifted away from the road surface according to the actual dredging operation requirements, effectively cleaning impurities at different positions and heights, and significantly enhancing the adaptability and operation convenience of the equipment to different working conditions.

[0030] When the cleaning vehicle 1 starts to work and slowly drives along the sides of the road for cleaning, the operator can adjust the horizontal angle and pitch attitude of the mechanical arm rod assembly through the control panel or remote control device to accurately aim the hose 8 at the garbage accumulation area, efficiently clean light impurities such as fallen leaves and silt on the roadside, and ensure the road surface to be clean and tidy.

[0031] On the other hand, a first conduit 9 is installed on the top of the second bin body 3, which is reliably connected with the suction pipe 10 by flange connection; similarly, a second conduit 11 is also provided on the top of the third bin body 4, which is also connected with the suction pipe 10, and a mud-water separation device 12 is installed on one side of the third bin body 4, which adopts existing mature technology structure and can efficiently separate and process the mud-water mixture, the inlet of which is in communication with the inside of the third bin body 4, and the outlet is connected to the second bin body 3 by pipeline, so as to transport the separated liquid into the second bin body 3 for storage, for recycling by the cleaning vehicle during operation, effectively improving the utilization efficiency of water resources.

[0032] The bottom of the suction pipe 10 is provided with a telescopic structure, which is an electric control structure and can be controlled by the vehicle-mounted system to approach or not approach the road surface.

[0033] The device realizes the cleaning of the road surface and the drainage system through the classification and treatment of various pollutants such as accumulated water, dry garbage, wet garbage and sludge by the division of the upper and lower cleaning assemblies and the multi-bin body system, and ensures the smoothness of the drainage system.

[0034] By starting the driving member matched with the suction pipe 10 (the driving member is arranged inside the bin body and provides negative pressure suction), the suction pipe 10 can effectively clean the silt on both sides of the road. The system supports two cleaning modes: the first mode is suitable for the condition of small rainfall, at this time the suction pipe 10 transports the silt mixture sucked into the second conduit 11, enters the third bin body 4 for temporary storage, and then the mixture enters the sludge-water separation device 12 for separation treatment, and the separated solid silt is accumulated in the device, and the separated liquid is transported into the second bin body 3 for subsequent circulation operation. The second mode is suitable for heavy rainfall weather, at this time the silt liquid is directly transported into the first conduit 9 through the suction pipe 10, and then enters the second bin body 3 for temporary storage. In the case of light rain, the silt is accumulated on both sides of the road, the solid content of the suction is high, and the liquid can be reused after being treated by the sludge-water separation device; in the case of heavy rain, the silt is washed and flows, the water content in the suction is high, and the silt amount is small, which can be directly stored in the second bin body 3 as working water for circulation, saving the separation link and improving the operation efficiency.

[0035] Both modes realize the recycling of water resources, improve the resource efficiency, and improve the automation and operation efficiency of silt cleaning through the electric control telescopic structure and negative pressure driving.

[0036] The lower cleaning assembly is composed of a shell 13 fixedly installed at the bottom of the cleaning vehicle 1, a reinforcing frame 14 is arranged at the front side of the shell 13, the design of the reinforcing frame 14 can further improve the overall structural stability and vibration resistance of the lower cleaning assembly, and a driving mechanism 15 is fixedly installed on one side of the shell 13, and a first dredging assembly is arranged at the front end of the driving mechanism 15, and the driving mechanism 15 provides power support for the first dredging assembly;

[0037] The first dredging assembly includes a first track 16 fixedly connected to the front end of the driving mechanism 15, a cleaning rod 17 is slidably arranged at the bottom of the first track 16, a first motor 18 is fixedly installed at the end of the cleaning rod 17, and a stirring disc 19 is fixedly installed at the output end of the first motor 18. The stirring disc 19 can rotate under the drive of the motor to crush the silt;

[0038] The bottom of the driving mechanism 15 is provided with a hydraulic telescopic structure 26, and the output end of the hydraulic telescopic structure 26 is fixedly connected to the first track 16, so that the overall lifting of the first dredging assembly is realized by controlling the telescopic movement of the hydraulic telescopic structure 26, and the first dredging assembly can flexibly adjust the height and approach the ground to perform the dredging operation;

[0039] The two sides of the tamping disc 19 are provided with spray pipes 20 connected with the second bin body 3. Liquid in the second bin body 3 is delivered to the spray pipes 20, and finally sprayed out of the spray pipes 20 to assist in dredging. The pipes connected with the spray pipes 20 are made of flexible material, which can freely stretch and contract with the movement of the cleaning rod 17, ensuring smooth liquid delivery.

[0040] The bottom of the driving mechanism 15 is also provided with a second dredging assembly, which is also powered by the driving mechanism 15 to realize the cooperative operation of multiple dredging functions.

[0041] The second dredging assembly includes a middle track 21 fixedly installed at the bottom of the shell 13. A plurality of desilting assemblies are slidably connected to the middle track 21. These desilting assemblies are specially used for cleaning the silt in the pipe opening area of the drainage pipe on both sides of the highway and can extend into the interior of the drainage pipe for cleaning operation.

[0042] The desilting assembly includes a second motor 27 slidably connected to the middle track 21. The output end of the second motor 27 is fixedly installed with a first telescopic rod 22. The end of the first telescopic rod 22 is fixedly installed with a support column 23. A plurality of second telescopic rods 24 vertically arranged are provided on the side wall of the support column 23. These second telescopic rods 24 are jointly connected to a scraper 25. A cleaning structure such as a plastic brush or other replaceable cleaning component is detachably installed on the outer side wall of the scraper 25 to adapt to different cleaning needs.

[0043] The drainage system of the highway pavement mainly includes three modes: the first drainage mode, the second drainage mode and the third drainage mode. The drainage channel of the first drainage mode crosses the highway pavement, which is used to guide the rainwater to both sides of the highway. The drainage channel of the second drainage mode is arranged on both sides of the highway, which is convenient for collecting the water flowing on the pavement. The third drainage mode of the highway is an overhead structure, which transports the rainwater to the ground through the pipeline.

[0044] For the first drainage mode of the highway, the cleaning vehicle 1 drives to a predetermined position on one side of the highway, and then the vehicle-mounted system drives the hydraulic telescopic structure 26 to operate, the hydraulic telescopic structure 26 is lowered to drive the first dredging assembly to be lowered to the channel on the highway pavement, and then the cleaning rod 17 is driven to move along the first track 16 and gradually extend out of the first track 16. With the movement of the cleaning rod 17, the first motor 18 drives the beater 19 to move synchronously, and the first motor 18 drives the beater 19 to rotate continuously during the movement, so as to effectively break the sludge in the channel, thereby facilitating the further advancement of the cleaning rod 17. This dredging method can regularly clean the sludge on the highway pavement, significantly reducing the occurrence of highway water accumulation. If the sludge is seriously caked, the vehicle-mounted system can control the liquid in the second bin body 3 to be delivered to the spray pipe 20 to assist the beater 19 to break the sludge cake more efficiently. This dredging method is suitable for a channel depth of about a, and the thickness of the cleaning rod 17 is designed to be less than or equal to a, so that it can smoothly enter the channel. If manual or other equipment is used for dredging, on the one hand, it will occupy the normal driving lane of the highway, causing interference to high-speed vehicle traffic, and on the other hand, the dredging efficiency is low. The dredging structure of the cleaning vehicle 1 allows the cleaning vehicle 1 to be parked on the roadside and perform dredging operations along the channel, which has no effect on the passing vehicles on the highway. Compared with the traditional manual or equipment dredging method, which needs to occupy the lane and interfere with traffic, the device can be parked on the roadside for operation, avoiding the influence on the highway traffic. At the same time, the automatic dredging process reduces the intensity of manual operation and reduces the safety risk of operation.

[0045] For the second drainage mode of the highway, the cleaning vehicle 1 can directly use the liquid in the second bin body 3 to perform high-pressure flushing on the drainage channel to clean the thin layer of sludge attached in the channel. The bottom of the drainage channel is usually connected with a sewer, and the attached sludge layer is thin, so that the flushing method can efficiently complete the cleaning task;

[0046] For the third drainage mode of the highway, after the cleaning vehicle 1 drives to a suitable position, the vehicle-mounted system drives the second motor 27 to move along the middle track 21 to the target position, and then the first telescopic rod 22 is lowered to drive the support column 23 and the second telescopic rod 24 to be lowered synchronously, and the second telescopic rod 24 further drives the scraper 25 to be lowered. The bottom of the scraper 25 is designed as a blade structure, which can smoothly cut into the sludge cake when the highway drainage pipe opening encounters a sludge cake. Then, the second motor 27 is started to drive the support column 23 to rotate, and the rotation of the support column 23 further drives the second telescopic rod 24 and the scraper 25 to rotate together, thereby breaking and cleaning the sludge in the pipe opening. At the same time, according to the specific size of the pipe opening, the vehicle-mounted system can drive the second telescopic rod 24 to adjust the extension and contraction, so as to change the position of the scraper 25, so that it can clean the inner wall of the pipe opening comprehensively, avoiding the influence of sludge cake attachment on the drainage effect.

[0047] In conclusion, the dredging device realizes efficient, safe and comprehensive cleaning of the highway drainage system by means of functional modularization, operation automation, scene adaptability and resource recycling, and significantly improves the comprehensive benefits of the cleaning operation.
