All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0018] Embodiment 1:

[0019] Please refer to Figures 1-3 , a stirring and suction type underwater air-compressed mud suction device, which includes a mounting frame 1, a hydraulic mud stirring system, and an air-compressed mud suction system. The hydraulic mud stirring system and the air-compressed mud suction system are arranged on the surface of the mounting frame 1. The hydraulic mud stirring system includes a hydraulic pump, an oil delivery pipe 3, a hydraulic motor 4, a filter 5, and mud stirring teeth. A channel steel gantry fixing frame 2 is fixedly installed on the upper surface of the mounting frame 1. The oil delivery pipe 3 is fixedly installed on the surface of the channel steel gantry fixing frame 2. The hydraulic motor 4 is fixedly installed on the upper surface of the mounting frame 1. The filter 5 is fixedly installed on the upper surface of the channel steel gantry fixing frame 2. A mounting plate 6 is fixedly installed on the lower surface of the mounting frame 1. Stirring mud teeth 7 are fixedly installed on the lower surface of the mounting plate 6.

[0020] Specifically: During the use of the present utility model, the hydraulic pump is started. The hydraulic pump delivers high-pressure hydraulic oil to the hydraulic motor 4, which is an actuator of the hydraulic mud stirring system, through the oil delivery pipe 3. The hydraulic motor 4 converts hydraulic pressure energy into mechanical energy, drives the bearing of the mud stirring teeth to rotate, so that the stirring mud teeth 7 rotate at a high speed, thereby crushing the soil and mixing it with the river water. The mixture after mixing is transported to the outside through the mixing slurry delivery pipe 9.

[0021] In this implementation scheme: The hydraulic pump is selected as the BP5660 type oil pump, and the hydraulic motor 4 is selected as the NHM1004.

[0022] Specifically: One hydraulic motor 4 drives one rotating mud stirring tooth. Bolt holes are arranged at the position of the hydraulic motor 4 corresponding to the channel steel gantry fixing frame 2. The hydraulic motor 4 is fixed up and down with M10 bolts, which is convenient for disassembly and repair when damaged. At the same time, the seals of the shaft and the oil chamber of the hydraulic motor 4 are advanced and reliable, and there is anti-leakage protection; the bottom rotating bearing of the hydraulic motor 4 passes through and is connected to the stirring mud teeth 7.

[0023] In this implementation plan: The oil pipeline 3 uses a steel pipe with a diameter of φ48mm and a wall thickness of 2.5mm and a high-pressure hose with a diameter of φ48mm and a wall thickness of 3mm. The lower end of the oil pipeline 3 is fixedly connected to the surface of the hydraulic motor 4. The upper end of the oil pipeline 3 can be externally connected to a hydraulic pump. The filter 5 is selected as the ZU-H63*20L type filter 5. The mixing mud teeth 7 are selected as spiral drills purchased on the market, which are cold-drawn once after heat treatment. The blade thickness is 18mm, the maximum diameter of the blade is 0.9m, which is thickened and wear-resistant, and has a double-piece and double-tooth symmetrical design.

[0024] Specifically: Near the conveying pipe, a steel plate with a length of 10cm, a width of 4cm, and a thickness of 2cm can be used for fixing, and the steel pipe pile is welded and fixed to the concrete conveying pipe. The lower end of the oil pipeline 3 is connected to the hydraulic rotators at both ends; the free part of the upper end of the oil pipeline 3 is connected to the hydraulic pump by a high-pressure hose, which is convenient for movement. The hydraulic pump is installed at a fixed location and installed on the water. The hydraulic oil is conveyed into the hydraulic motor 4 through a high-pressure pipe to form a mud stirring effect. It is not easily damaged away from the water surface. By selecting a mud stirring drill bit with a large blade thickness and optimizing the material, its wear resistance, toughness, and strength are improved. The drill bit can better cope with high loads and frequent use, reduce the replacement frequency, and lower the maintenance cost. A ZU-H63*20L type filter 5 is respectively arranged on both sides of the hydraulic motor 4 to play a protective role for the hydraulic motor 4.

[0025] Working principle: Through the cooperative setting of the hydraulic pump and the oil pipeline 3 in the present utility model, the rotation of the mixing mud teeth 7 is realized. Compared with the related technology, a stirring and suction type underwater air compressor mud suction device provided by the present utility model has the following beneficial effects: This design can realize the function of crushing the soil and mixing it with the river water, effectively destroying the soil structure, thus avoiding the situation where the soil cannot be pumped out, greatly improving the efficiency, and having strong adaptability.

[0026] Embodiment 2:

[0027] Please refer to Figures 1-3 The upper surface of the mounting frame 1 is fixedly installed with an air delivery pipe 8, and the middle part of the channel steel gantry fixing frame 2 is fixedly installed with a mixed slurry delivery pipe 9.

[0028] Specifically: In this utility model, when the stirring is completed, the air compressor starts at this time. The air compressor compresses the gas. The compressed gas is conveyed to the bottom of the mixed slurry delivery pipe 9 through the air delivery pipe 8. At this time, the high pressure and high-speed moving ability of the gas drive the water and slurry in the mixed slurry delivery pipe 9 to the upper end of the pipe, thus generating a water pressure balance difference at the bottom end of the mixed slurry delivery pipe 9. The water pressure at the bottom of the pipe orifice is higher than the water pressure in the mixed transportation pipe, causing the slurry at the low end of the pipe orifice to flow to the low-pressure area due to the release of the external high-pressure potential energy, resulting in the suction of the stirred water and slurry moving into the mixed transportation pipe, thus achieving the purpose of mud suction and water pumping.

[0029] In this implementation scheme: The upper end of the air delivery pipe 8 can be externally connected to an air compressor. The air compressor selected is a MAM-880 screw air compressor with an air production capacity of 7 - 43 m³ / min. The air delivery pipe 8 is made of a steel pipe with a diameter of φ48mm and a wall thickness of 2.5mm and a high-pressure hose with a diameter of φ48mm and a wall thickness of 3mm. The mixed slurry delivery pipe 9 is made of a flange seamless steel pipe with a diameter of 32cm and is connected and lengthened using M20 bolts. Steel pipes of different lengths can be selected for adaptive adjustment according to the needs of the construction site.

[0030] Specifically: The joints of the air delivery pipe 8 are fixed using chuck joints. The part that extends into the water uses a steel pipe as the air delivery pipe 8. A steel plate with a length of 10cm, a width of 4cm, and a thickness of 2cm is used to weld and fix the air delivery steel pipe parallel to the mixed slurry outlet pipe. One fixing steel plate is provided every 1 meter. The free part at the upper end of the air delivery pipe 8 is connected to the air compressor using a high-pressure hose, which is convenient for the movement of mud suction equipment and increases the operating space. The air delivery pipe 8 is arranged outside the mixed slurry delivery pipe 9 and is vertically welded and fixed using steel pipes and steel plates, without any entanglement or blockage. The air compressor is installed on a fixed platform and is installed on the water. High-pressure gas is transported through the air delivery pipe 8 into the mixed slurry delivery pipe 9 in the water to form a mud suction effect. It is not easily damaged away from the water surface. The bottom end of the mixed slurry delivery pipe 9 passes through the channel steel gantry fixing frame 2 and extends 20cm into the channel steel gantry fixing frame 2, and is welded and fixed to the channel steel gantry fixing frame 2 at the same time. At the four corners of the channel steel gantry fixing frame 2, 4 I16 steel bars are used to weld the channel steel gantry fixing frame 2 and the mixed slurry delivery pipe 9 at a 45° angle to form an integral structure. A round hole with a diameter of 48mm is provided 10cm away from the bottom opening of the mixed slurry outlet pipe and is welded to the air delivery pipe 8.

[0031] Working principle: In this design, after the air compressor compresses the gas into high-pressure gas, the high-pressure gas is used to transport the slurry and water. Compared with the related technology, a stirring and suction type underwater air compressor mud suction device provided by the present utility model has the following beneficial effects: This design can achieve the effect of transporting slurry and water, has few internal parts, a simple overall structure, no vulnerable parts, a long service life, and high reliability.

[0032] For the selection of each device in the above-mentioned equipment usage, different selections are made according to the actual situation, and various parameters are referred to, and the functions of the used equipment are coordinated with the achieved effects.

[0033] Although the embodiments of the present utility model have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present utility model. The scope of the present utility model is defined by the appended claims and their equivalents.
