Description

Technical Field

[0001] The utility model relates to the technical field of underwater debris cleaning equipment, in particular to a pneumatic lifting equipment for cleaning underwater debris. Background Art

[0002] During the annual inspection of the offshore oil platform jacket, since the platform is a fixed platform, it is necessary to conduct regular inspection and cleaning of the jacket in accordance with relevant specifications. The shells of cleaned marine organisms (oysters, shellfish, conchs, etc.) and silt sediments in the marine environment will bury the structural parts close to the seabed. Since the structural parts need to be cleaned regularly, equipment that can clean silt and marine organisms is needed for divers to carry underwater for cleaning.

[0003] For existing equipment, divers usually carry fire hoses and use water guns to clean the buried sludge underwater. Or use air lifting pumps to clean the sludge. Using a water gun to blow requires taking fire water from the water surface. The water depth is more than 20 meters. Under the influence of ocean currents, it is difficult for divers to control the water gun belt and the reaction force of the water gun underwater. There are also water pumps placed underwater to reduce the length of the leather dragon belt to reduce the consumption of the leather dragon belt by ocean currents. However, the disadvantage is that the voltage of the water pump is 380V, and once leakage occurs, it will cause harm to divers. Using a water gun to blow, the shells of buried marine organisms are solid objects, and they will quickly return to their original lows under the influence of ocean currents. The previous air lifting equipment was large in size, and it was difficult for divers to carry the equipment to the designated location. In addition, air lifting equipment is generally equipped with a filter device, and the pump head is also prone to clogging.

[0004] Therefore, how to provide a pneumatic lifting device for cleaning underwater debris to solve the defects of existing cleaning equipment is a technical problem that needs to be urgently solved by technical personnel in this field. Utility Model Content

[0005] To this end, the utility model provides an underwater debris cleaning pneumatic lifting device to solve the problem in the prior art that the cleaning equipment is relatively bulky and requires a higher voltage to use, which results in the inability to be brought to underwater operations and poses a safety hazard.

[0008] A pneumatic extraction pipeline, the bottom of which is arranged on the surface of the underwater component and the upper end of which is provided with a discharge pipe;

[0009] A pneumatic assembly is arranged on the left side of the pneumatic extraction pipeline, and the pneumatic assembly is connected to the pneumatic extraction pipeline via a connecting plate;

DETAILED DESCRIPTION

[0040] The following is a specific embodiment of the present invention. People familiar with the technology can easily understand other advantages and functions of the present invention from the contents disclosed in this specification. Obviously, the described embodiment is a part of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0041] Please refer to Figure 1-Figure 5 Now, the utility model discloses a kind of underwater debris cleaning pneumatic lifting equipment to explain, the utility model is composed of eight parts, such as Figure 1, including an intake and exhaust pipeline 1, an exhaust gas exhaust pipeline 2, a pneumatic extraction pipeline 3, a connecting plate 4, a drainage pipeline 5, a pneumatic component 6, a handle 7 and an air suction component 8. The bottom of the pneumatic extraction pipeline 3 is arranged on the surface of the underwater component, and a discharge pipe is installed on the upper end. The pneumatic component 6 is arranged on the left side of the pneumatic extraction pipeline 3. The pneumatic component 6 and the pneumatic extraction pipeline 3 are connected through a connecting plate 4. One end of the drainage pipeline 5 is installed on the left side below the pneumatic component 6, and the other end of the drainage pipeline 5 is connected to the leather dragon belt. The air suction component 8 is installed above the pneumatic component 6. The upper end of the air suction component 8 is connected to the intake pipeline. The right end of the air suction component 8 is connected to the intake and exhaust pipeline 1. The right end of the intake and exhaust pipeline 1 is inserted in the pneumatic extraction pipeline 3, one end of the exhaust gas exhaust pipeline 2 is inserted in the pneumatic component 6, and the other end of the exhaust gas exhaust pipeline 2 is inserted in the pneumatic extraction pipeline 3. The handles 7 are arranged in pairs and are installed on the front and rear sides of the upper end of the pneumatic component 6. The exhaust gas exhaust pipeline 2 is arranged below the intake and exhaust pipeline 1.

[0042] When the utility model is in use, the air suction component 8 is connected to the air intake pipeline, and then the drainage pipeline 5 is connected to the leather dragon belt. After the connection is completed, the pneumatic component 6 is started. The pneumatic component 6 will suck in the outside air from the intake pipeline, and then absorb water through air drive. The water flow changes its flow rate under the drive of the air, forming a high-pressure water flow flowing out from the discharge pipeline 5. The high-pressure water flow can blow away underwater marine organisms and silt. At this time, the used air will enter the pneumatic extraction pipeline 3 through the tail gas exhaust pipeline 2, and the underwater debris will be discharged through the discharge pipe through the "negative pressure" generated by the rising air to complete the cleaning operation. The setting of the air intake and exhaust pipeline 1 is used when the internal air pressure of the pneumatic extraction pipeline 3 is insufficient or the internal stability needs to be adjusted.

[0043] In a specific embodiment, Figure 2 The air inhalation assembly 8 includes a pipe connector 81, a three-way connecting pipe 82 and a connecting block 83. The connecting block 83 is installed above the pneumatic assembly 6. The three-way connecting pipe 82 is inserted above the connecting block 83. One end of the air intake and exhaust pipeline 1 is inserted on the right side of the three-way connecting pipe 82. The pipe connector 81 is installed above the three-way connecting pipe 82. The upper end of the pipe connector 81 is inserted with an air intake pipeline. The connecting block 83 is provided with an air supply pipeline, which extends upward to the pipe connector 81 and extends downward to the pneumatic assembly 6. The air flow channel is increased by the arrangement of the three-way connecting pipe 82, so that the inhaled air can enter the pneumatic extraction pipeline 3 through the air intake and exhaust pipeline 1, and the air flows to the pneumatic assembly 6 through the air supply pipeline. The top of the connector 81 is a 1.5-inch air inlet.

[0044] In a specific embodiment, a flange is provided at the upper end of the pneumatic extraction pipe 3, and the pneumatic extraction pipe 3 is connected to the discharge pipe by a flange. A mounting hole is provided on the side of the pneumatic extraction pipe 3, and the mounting holes are arranged in pairs, and the exhaust gas pipeline 2 and the intake exhaust pipeline 1 are inserted into the mounting holes. The flange connection not only makes the installation more secure, but also has stronger impact resistance, and can effectively prevent leakage. The mounting holes are used to fix the exhaust gas pipeline 2 and the intake exhaust pipeline 1 by welding, which can effectively prevent leakage.

[0045] In a specific embodiment, Figure 3 The pneumatic assembly 6 includes an exhaust pipe 61, a water inlet pipe 62, a circular hole 63, a drainage pipe 64, a mounting block 65 and a mounting member 66. The exhaust pipe 61 is installed on the bottom side of the mounting member 66, and one end of the tail gas exhaust pipe 2 is inserted in the exhaust pipe 61. An air pump is arranged inside the mounting member 66. The mounting block 65 is installed below the mounting member 66. A plurality of mounting plug rods are installed on the upper side of the mounting block 65, and a connecting plate 4 is inserted above the mounting plug rods. The water inlet pipe 62 is installed at the bottom of the mounting block 65, and a plurality of circular holes 63 are opened on the side wall of the water inlet pipe 62. The drainage pipe 64 is arranged on the outer side of the lower part of the mounting block 65, and one end of the drainage pipe 64 is inserted in the mounting block 65, and the other end of the drainage pipe 64 is connected to the drainage pipe 5. When the pneumatic component 6 is in use, the air pump is first started to extract air. The high-flow air will draw water into the mounting block 65 along the circular hole 63. At this time, the water flow rate increases and flows out through the drainage pipe 64. The outflowing water is high-pressure water, which is discharged through the discharge pipe 5. The high-pressure water is used to spray silt and marine organisms. The exhaust pipe 61 is used to discharge the used air. The method of using the pneumatic component 6 is similar to the method of using a traditional pneumatic submersible pump.

[0046] In a specific embodiment, Figure 4 The tail gas exhaust pipe 2 includes a second tail gas exhaust pipe body 21 and a first tail gas exhaust pipe body 22. One end of the first tail gas exhaust pipe body 22 is inserted in the pneumatic assembly 6, and one end of the second tail gas exhaust pipe body 21 is inserted in the pneumatic extraction pipe 3. The second tail gas exhaust pipe body 21 is arranged above the first tail gas exhaust pipe body 22. The second tail gas exhaust pipe body 21 is connected to the first tail gas exhaust pipe body 22 through a flange. The used air enters the pneumatic extraction pipe 3 through the second tail gas exhaust pipe body 21 and the first tail gas exhaust pipe body 22.

[0047] In a specific embodiment, Figure 5The air intake and exhaust pipeline 1 includes an air intake and exhaust pipe body 11 and a control valve 12. One end of the air intake and exhaust pipe body 11 is inserted in the air suction assembly 8, and the other end of the air intake and exhaust pipe body 11 is inserted in the pneumatic extraction pipeline 3. The control valve 12 is installed in the air intake and exhaust pipe body 11. By setting the control valve 12, the problem that the pressure of the used air in the pneumatic extraction pipeline 3 is insufficient to drive the discharge of marine organisms and sludge is solved. At the same time, the air in the air intake and exhaust pipe body 11 and the used air work together to accelerate the sewage discharge efficiency and ensure the stability of the gas flow direction inside the pneumatic extraction pipeline 3.

[0048] Although the utility model has been described in detail above with general descriptions and specific embodiments, it is obvious to those skilled in the art that some modifications or improvements can be made to the utility model. Therefore, these modifications or improvements made without departing from the spirit of the utility model are within the scope of protection claimed by the utility model.
