Description

Technical Field

[0001] The invention relates to the technical field of deep sea exploration pumps, in particular to a pressure-resistant and corrosion-resistant pump for deep sea exploration. Background Art

[0002] With the continuous development of marine resources and deep-sea scientific research, the performance requirements for deep-sea exploration equipment are becoming increasingly stringent. Among many deep-sea exploration equipment, pumps, as key components, undertake the important task of transporting various liquids. Their performance directly affects the stability and reliability of the entire detection system. The deep-sea environment has extremely high pressure. Generally, the pressure increases by about 1 atmosphere for every 10 meters of descent. At the bottom of the sea thousands of meters deep, the pressure can reach hundreds of atmospheres. At the same time, deep-sea water is rich in a variety of corrosive substances, such as chloride ions, sulfate ions, etc. When the pump body is fixed on the detection ship for use, these substances will react with the metal parts of the pump in a complex chemical reaction, causing corrosion and wear of the pump body, thereby affecting its normal operation.

[0003] Some pumps use corrosion-resistant coatings, which alleviate the corrosion problem to a certain extent. However, the coating is prone to falling off when washed by high-pressure and high-velocity seawater, and cannot continuously and effectively protect the pump body.

[0004] According to the description of an offshore wind turbine power generation and breeding system published on the patent website (authorization announcement number: CN116098100B), the offshore wind turbine power generation and breeding system includes "wind turbine platform, delivery pump, fill light board" etc. to carry out breeding work.

[0005] In view of the above description, the applicant believes that there are the following problems: The offshore wind turbine power generation and breeding system uses a wind turbine platform, a delivery pump, a fill light panel, etc. to carry out breeding work. During the use of this system, the delivery pump transports the algae in the algae breeding box to the fish breeding cage. The delivery pump is fixed on the top of the algae breeding box. Because there is no external protection and anti-corrosion work, seawater is a highly corrosive medium containing a large amount of salt, chloride and other substances. The delivery pump is exposed to seawater for a long time, and its metal parts such as the impeller and pump casing will undergo electrochemical corrosion, affecting the normal operation and service life of the pump, so this system needs to be improved.

[0016] According to the above technical solution, the first clamping shaft passes through the inside of the second rotating rod, and clamping grooves are respectively opened inside the second rotating rod and the fixed rod, and the two clamping grooves correspond to each other. The first clamping shaft is inserted into the clamping groove, so that when it is necessary to drive the second rotating rod to rotate through the fixed rod, the fixed rod and the second rotating rod can be easily assembled and disassembled under the action of the first clamping shaft.

[0017] Compared with the prior art, the beneficial effects achieved by the present invention are: 1. The pressure-resistant and corrosion-resistant pump for deep-sea exploration, through the protective components set, when the pump body is used for deep-sea exploration and fixed on the ship through the base, the servo motor drives the gear and the first sprocket fixedly connected to the periphery of the first rotating rod to rotate, so that the first sprocket drives the second sprocket and the fixed rod to rotate through the chain, and the second rotating rod and the protective shell are driven to rotate through the fixed rod, so that the protective shell is located at the periphery of the pump body to protect it. When there are foreign objects in the deep sea that may hit the pump body, the protective shell uses its corrosion-resistant and pressure-resistant material to provide reliable physical protection for the pump body, greatly reducing the risk of the pump body being compressed due to external impact, while avoiding the erosion of the pump body by seawater, and playing a corrosion-resistant effect. The two sets of symmetrically distributed and mutually meshing protective components can flexibly adjust the position of the protective shell according to actual needs. When the pump body needs to be maintained or debugged, the protective shell can be opened by controlling the servo motor to reverse, which is convenient for the staff to operate. In normal operation, the protective shell tightly wraps the pump body to ensure the protective effect, and can drive the connecting shaft to rotate under the action of the first rotating rod, providing power for the filter assembly to clean the filter plate, and realizing the linkage effect with the filter assembly.

[0018] 2. The pressure-resistant and corrosion-resistant pump for deep-sea exploration has a filter assembly. When the pump body is used for deep-sea exploration and fixed on a ship, the external connecting pipe can be connected to the water inlet on the left side of the pump body through the sealing pipe and the fixing pipe. When the connection is completed, the adjusting shaft is rotated to make the adjusting shaft drive the limit frame to move, so that the limit frame moves to the top of the sealing pipe to limit the filter plate. Under the action of the filter plate, the seawater sucked into the pump body can be filtered. There are various suspended particles, plankton, algae and other impurities in the seawater. If these impurities enter the pump body and related equipment, it may cause the pipeline, valve, impeller and other components to be blocked, affecting the normal operation of the pump. At the same time, filtration can remove impurities in the seawater. and interfering substances, making the seawater sample more representative. The movement of the limit frame will drive the first plug block to be inserted into the sealing tube, ensuring the stability between the sealing tube and the fixed tube while facilitating installation and disassembly. When the filter plate is used for a long time, the concave frame can be squeezed by the extrusion wheel under the action of the first rotating rod and the connecting shaft, so that the concave frame drives the sliding rod, the cleaning brush and the telescopic rod to move, and the second spring is deformed, so that the impurities attached to the filter plate can be cleaned under the action of the cleaning brush to avoid clogging, thereby realizing the linkage effect between the filter assembly and the protective assembly, and the limit frame will be slidably connected to the periphery of the limit frame when it moves, further limiting the sealing plate, and forming a linkage with the sealing mechanism.

[0019] 3. The pressure-resistant and corrosion-resistant pump for deep-sea exploration has a sealing mechanism. When the protective shell is located outside the pump body for protection, the sealing plate is initially limited under the action of the limit rod. At this time, the pull ring can be pulled to the left to drive the limit rod to move, and the first spring can be deformed to release the limit on the sealing plate. The sealing plate can be limited under the elastic action of the third spring, so that the sealing plate is slidably connected to the periphery of the pump body, and the gap between the protective shell and the pump body is further sealed, ensuring a good seal between the pump body and the external environment, further enhancing the sealing effect, and effectively preventing seawater from leaking into the pump body. When the sealing plate is slidably connected to the periphery of the pump body, it will drive the limit frame, the plug rod, the connecting plate and the second plug block to move, so that the plug rod is plugged into the inside of the filter plate to further fix it, and at the same time, the second plug block is plugged into the inside of the sealing tube to further ensure the stability between the sealing tube and the fixed tube, and the limit frame will be slidably connected to the periphery of the sealing tube to limit the top of the filter plate to ensure the stability of the filter plate and the sealing tube.

[0020] 4. The pressure-resistant and corrosion-resistant pump for deep-sea exploration has a limit mechanism. When it is necessary to drive the second rotating rod to rotate through the fixed rod and drive the protective shell to rotate to the periphery of the pump body to protect it and achieve corrosion resistance, it is only necessary to insert the first clamping shaft into the fixed rod and the second rotating rod, so that the disc, the mounting frame, the first clamping shaft, the fourth spring and other components can rotate together with the second rotating rod. When the protective shell is outside the pump body, the disc rotates exactly one circle, and the handle is pulled downward to separate the handle from the fixed rod. The limit shaft is rotated to be in a vertical state, and the handle is supported in the state of the limit shaft, so that the handle drives the second clamping shaft to be inserted into the base, which can ensure that the disc is in a completed state, ensure the stability of the protective shell, and make the second rotating rod no longer rotate with the fixed rod, thereby not affecting the drive of the fixed rod, thereby realizing the linkage between the limit mechanism and the protective component.

The two sets of symmetrically distributed and mutually meshing protective components 21 can flexibly adjust the position of the protective shell 213 according to actual needs. When the pump body 5 needs to be maintained or debugged, the protective shell 213 can be opened by controlling the servo motor 211 to reverse, which is convenient for the staff to operate. In normal operation, the protective shell 213 tightly wraps the pump body 5 to ensure the protective effect. When the protective shell 213 is outside the pump body 5, the disc 42 rotates exactly one circle, and the handle 47 is pulled downward to separate the handle 47 from the inside of the fixed rod 2194, and the limit shaft 44 is rotated to make it in a vertical state. The handle 47 is supported in the state of the limit shaft 44, so that the handle 47 drives the second clamping shaft 48 to be plugged into the inside of the base 1, which can ensure that the disc 42 is in a completed state, ensure the stability of the protective shell 213, and make the second rotating rod 2196 no longer rotate with the fixed rod 2194, so as not to affect the driving of the fixed rod 2194; By connecting the external connecting pipe 223 through the sealing pipe 222 and the fixed pipe 221, it can be connected to the water inlet on the left side of the pump body 5, and at the same time connected to the top of the pump body 5 through the external pipeline. When the connection is completed, the adjusting shaft 2293 is rotated to make the adjusting shaft 2293 drive the limiting frame 2294 to move, so that the limiting frame 2294 moves to the top of the sealing pipe 222, and limits the filter plate 224. Under the action of the filter plate 224, the seawater sucked into the pump body 5 can be filtered. There are various suspended particles, plankton, algae and other impurities in the seawater. At the same time, the filtration can remove impurities and interfering substances in the seawater, making the seawater sample more representative. The movement of the limiting frame 2294 will drive the first plug-in block 2295 to be plugged into the inside of the sealing pipe 222, ensuring the stability between the sealing pipe 222 and the fixed pipe 221 while facilitating installation and disassembly; When the protective shell 213 is at the periphery of the pump body 5 for protection, the sealing plate 35 is initially in a limited position under the action of the limit rod 219. At this time, the pull ring 217 can be pulled to the left, so that the pull ring 217 drives the limit rod 219 to move, and the first spring 218 is deformed to release the limit on the sealing plate 35. The sealing plate 35 can be limited under the elastic action of the third spring 33, so that the sealing plate 35 is slidably connected to the periphery of the pump body 5, and the gap between the protective shell 213 and the pump body 5 is further sealed, ensuring a good seal between the pump body 5 and the external environment, further enhancing the sealing effect, effectively preventing seawater from leaking into the pump body 5, and the sealing plate 3 When the limiting frame 2294 is slidably connected to the periphery of the pump body 5, it will drive the limiting frame 34, the plug rod 37, the connecting plate 36 and the second plug block 38 to move, so that the plug rod 37 is plugged into the inside of the filter plate 224 to further fix it, and at the same time, the second plug block 38 is plugged into the inside of the sealing tube 222 to further ensure the stability between the sealing tube 222 and the fixing tube 221, and the limiting frame 34 is slidably connected to the periphery of the sealing tube 222 to limit the top of the filter plate 224 to ensure the stability of the filter plate 224 and the sealing tube 222. When the limiting frame 2294 moves, it will be slidably connected to the periphery of the limiting frame 34 to further limit the sealing plate 35, forming a linkage with the sealing mechanism 3; When the filter plate 224 is used for a long time, the concave frame 2298 can be squeezed by the squeezing wheel 226 under the action of the first rotating rod 212 and the connecting shaft 225, so that the concave frame 2298 drives the sliding rod 2292, the cleaning brush 2291 and the telescopic rod 2297 to move, and the second spring 2296 is deformed, and the impurities attached to the filter plate 224 can be cleaned under the action of the cleaning brush 2291 to avoid clogging, thereby realizing the linkage effect between the filter component 22 and the protective component 21. The seawater after filtration will be discharged through the pipeline at the top of the pump body 5. When the filter plate 224 needs to be taken out for cleaning, it is only necessary to move the sealing plate 35 away from the periphery of the pump body 5, so that the insertion rod 37 releases the limit of the filter plate 224, and at the same time, the limit frame 2294 is moved away from a certain position on the top of the sealing tube 222 and then rotated, so that the limit of the filter plate 224 can be released, and the filter plate 224 can be taken out for cleaning.
