Description

Technical Field

[0001] The invention relates to the technical field of underwater pollution removal devices, and in particular to a crawler-type underwater mud obstacle and solid pollutant rolling and scraping machine and applications thereof. Background Art

[0002] The water environment is constantly being invaded by external pollution sources, and pollutants are constantly flowing into various water bodies. Most of the water pollutants are deposited on the surface of the bottom mud in the form of mud. These muds are precipitated later and contain a large amount of animal and plant remains. They are not completely decayed. The mass density of semi-rotten pollutants is relatively small. They are generally in a semi-settled state on the surface of the mud. In summer, the rising water temperature will accelerate the decay and decomposition, release nutrients to the water body, and endanger the water quality. Removing these pollutants is crucial to improving water quality. Now some underwater sewage extraction devices are based on the principle of vacuum cleaners and are specially used to extract the thin mud on the surface of the bottom mud that is most harmful to water quality. In order to ensure that these devices are always on the surface of the mud, they can be dragged to make soft contact with the mud. Due to the different conditions of the bottom of various water bodies, the bottom mud is uneven, and it is inevitable that there are a large number of solid pollutants and underwater obstacles, which bring great obstacles to the operation of the sewage extraction device. To solve this problem, the flatness of the bottom mud must be transformed to facilitate the operation of the sewage extraction device. Summary of the invention

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0024] The crawler-type underwater mud obstacle and solid pollutant rolling and scraping machine proposed by the present invention comprises a hull assembly, a connecting platform 6 and an underwater crawler-type hydraulic driving device 8;

[0025] The hull assembly includes a hull, a cabin 1 and a diesel tank 21. A cockpit 2 is provided at the front side of the hull, a diesel tank 21 is provided below the cockpit 2, a diesel generator 3 and a hydraulic system 4 are provided on the cabin 1, a propeller 51 and a rotating rod are provided at the rear side of the hull, and a propeller motor 5 for driving the rotating rod and the propeller 51 is provided at the rear of the cabin;

[0026] The connecting platform 6 is provided with three telescopic rods 11, the side of the hull is provided with a collar, the collar is sleeved on the telescopic rod 11, the lower part of the connecting platform 6 is installed above the underwater crawler hydraulic drive device 8, and the front and rear sides of the connecting platform 6 are respectively provided with a rolling structure and a scraping device;

[0027] The underwater crawler hydraulic drive device 8 includes a rolling crawler 82 and a hydraulic drive device 81 , and the hydraulic system 4 is connected to the hydraulic drive device 81 via a hydraulic power oil supply pipe.

[0028] When pumping sewage from the bottom of the water, if the bottom sludge is not flat, it will become difficult to pump sewage from the surface, resulting in incomplete sewage pumping and poor sewage pumping effect. Therefore, before pumping sewage, it is much more convenient and easier to roll or scrape the bottom sludge flat, and then pump sewage from the surface sludge of the bottom of the water. Therefore, the present application utilizes the rolling roller structure at the front end of the machine to play a role in pushing general obstacles and pollutants, and the scraping device scrapes the sludge flat again. The sewage squeezed out of the solid pollutants and the mixed mud will become flat after a few days of sedimentation, which is convenient for the subsequent sewage pumping operation.

[0029] A driving operation platform is provided in the cockpit 2.

[0030] On the one hand, after scraping and leveling, it can clear obstacles for the "sewage pumping device" to be used in the later operation. Another function is to redistribute the silt layers on the bottom of the water by mass by crushing the pollutants. Generally, the mass of rotten pollutants in a semi-decomposed state is relatively small. These tiny pollutants in a semi-decomposed state are the most harmful to the water environment. Due to their low mass density, they will settle on the surface. The "sewage pumping device" matched with this application is aimed at removing these semi-settled pollutants, so it can greatly improve the operating efficiency of the "sewage pumping device", which will play a great role in reducing the cost of pollution control.

[0031] The crawler-type underwater mud obstacle rolling and scraping machine has a hull on the upper part and an underwater crawler-type hydraulic drive device 8 (rolling and scraping) on ​​the lower part. The diesel generator 3 supplies power to the entire power system, and the operation is performed in the cockpit 2. The rolling roller structure rolls the silt that is compacted or contains a lot of water to squeeze out the water, and the scraping device scrapes the mud again.

[0032] The telescopic rod 11 includes a first connecting sleeve rod 111, a second connecting sleeve 112 and a third connecting sleeve 113. The first connecting sleeve rod 111 is sleeved on the second connecting sleeve 112, the second connecting sleeve 112 is sleeved on the third connecting sleeve 113, and the bottom end of the first connecting sleeve rod 111 is vertically fixed on the connecting platform 6.

[0033] The telescopic rod 11 can be extended, similar to the structure of a fishing rod. When the water is shallow, the retractable rod 11 automatically falls down. When the water is deep, the hull needs to extend the telescopic rod 11 to allow the boat to float on the water surface, and the ring on the boat is sleeved on the telescopic rod. When the underwater crawler hydraulic drive device 8 below is damaged and cannot travel, the telescopic rod is lowered or the ring is removed, so that the hull leaves the telescopic rod 11, and on the water surface, the propeller motor 5 drives the propeller 51 to make the hull move on the water surface.

[0034] The rolling roller structure includes a rolling roller 7, a rolling roller push rod 72 and a rolling roller hydraulic cylinder 71. The rotating shafts on both sides of the rolling roller 7 are respectively provided with a rolling roller push rod 72 and a rolling roller hydraulic cylinder 71. One end of the rolling roller push rod 72 is rotatably connected to the rotating shaft of the rolling roller 7, and the other end of the rolling roller push rod 72 is rotatably connected to the underwater crawler hydraulic drive device 8. The cylinder shaft of the rolling roller hydraulic cylinder 71 is rotatably connected to the rotating shaft of the rolling roller 7, and the rear end of the rolling roller hydraulic cylinder 71 is rotatably connected to the connecting platform 6.

[0035] When on the ground, the rolling roller 7 needs to be lifted so that it does not touch the ground. When working in water, the rolling roller 7 is lowered to make it contact the mud. The rolling roller hydraulic cylinder 71 can pull the rolling roller 7 so that the rolling roller 7 rotates along the rolling roller push rod 72 to achieve the effect of lifting the rolling roller 7 or lowering the rolling roller 7.

[0036] The rolling roller 7 is a roller with a plurality of protrusions 70 on its surface. The diameter of the roller is 1-1.5m. The protrusions 70 are pillars with a height of 10-15cm. The protrusions 70 can be inserted into the sludge to squeeze and disperse the compacted sludge, or squeeze out water in the sludge to make the sludge flat.

[0037] The scraping device includes a scraping shovel 9, a shovel push rod 92 and a shovel hydraulic cylinder 91. Rotating shafts are symmetrically arranged at the center positions on both sides of the scraping shovel 9. A shovel push rod 92 and a shovel hydraulic cylinder 91 are respectively arranged on the rotating shafts on both sides of the scraping shovel 9. One end of the shovel push rod 92 is rotatably connected to the rotating shaft, and the other end of the shovel push rod 92 is rotatably connected to the underwater crawler hydraulic drive device 8. The cylinder shaft of the shovel hydraulic cylinder 91 is rotatably connected to the rotating shaft of the scraping shovel 9, and the rear end of the shovel hydraulic cylinder 91 is rotatably connected to the connecting platform 6.

[0038] The raising or lowering of the scraping shovel 9 also utilizes the shovel hydraulic cylinder 91 to pull up or lower the scraping shovel 9 and raise or lower it along the shovel push rod 92. The scraping shovel 9 adopts conventional shovel to get final product, and it is OK that the mud scraping effect can be achieved.

[0039] There are two rolling tracks 82 , which are sleeved on a gear drum. The gear drum is driven to rotate by a hydraulic drive device 81 , which includes a driving hydraulic cylinder and a connecting rod structure thereon.

[0040] The underwater crawler hydraulic drive device 8 can be a conventional crawler excavator operating in mud.

[0041] A transmission reducer 52 is provided between the propeller motor 5 and the rotating rod, and one end of the rotating rod is connected to the output shaft of the transmission reducer 52. The transmission reducer 52 can effectively control the propeller 51, and the hull travels more smoothly.

[0042] The upper surface of the connecting platform 6 is a plane, the floor of the hull is a plane, and a rubber shock-absorbing pad is padded on the upper surface of the connecting platform 6. When operating in shallow water, the hull falls on the connecting platform 6, and the bottom of the hull contacts the connecting platform. Therefore, the contact between the two is a plane, and the rubber shock-absorbing pad is padded, so that the hull travels more smoothly without too much shaking, ensuring that the operation and driving are not affected.

[0043] The hydraulic system 4 is a plurality of hydraulic cylinders, and the rolling roller structure, the scraping device and the hydraulic drive device correspond to one hydraulic cylinder respectively. The rolling roller structure, the scraping device and the hydraulic drive device are driven independently, which is convenient for operation and conducive to controlling the operation effect.

[0044] The crawler-type underwater sludge obstacle and solid pollutant rolling and scraping machine described above is used in underwater sewage extraction. It is mainly used for rolling and scraping the underwater sludge, making the underwater sludge more stable and facilitating the subsequent surface sludge extraction.

[0045] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
