Description

Technical Field

[0001] This invention relates to the field of submersible pump technology, specifically a deep-well submersible pump with turbocharging function. Background Technology

[0002] With the continuous development of the oil extraction industry, deep-well submersible pumps play a crucial role in the oil extraction process. They are primarily used to extract oil or liquid media from deep wells and transport them to the surface, and their performance and efficiency directly affect the efficiency and cost of oil extraction. However, in practical applications, traditional deep-well submersible pumps face some technical problems that urgently need to be solved, which limit their application effectiveness and service life under complex working conditions.

[0003] First, the water inlet at the bottom of the inlet pipe of a deep well submersible pump is prone to clogging. This is because impurities and particles carried in the water can easily accumulate at the inlet as it flows through the inlet pipe, gradually reducing the flow area. Once the inlet is clogged, it severely affects the normal operation of the deep well submersible pump, reduces its efficiency, and may even cause equipment damage. Furthermore, traditional deep well submersible pumps experience significant pressure fluctuations during operation, which can impact critical components such as the motor, affecting the equipment's lifespan and stability. Therefore, effectively preventing clogging of the water inlet at the bottom of the inlet pipe and reducing the impact of water pressure fluctuations on the motor are problems that need to be solved in the field of deep well submersible pump technology. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides a deep well submersible oil pump with turbocharging function, which solves the problems mentioned in the background art, such as easy clogging of the water inlet hole at the bottom of the water inlet pipe and large fluctuations in water pressure leading to motor damage.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a deep-well submersible pump with turbocharging function, comprising: The drive unit contains an internal motor to provide power; Also includes: The water outlet mechanism has a turbine assembly inside, which is connected to the drive device and is used to transport the medium; The water inlet mechanism is installed on the top of the drive device; A pressure stabilizing mechanism is located at the top of the water inlet mechanism and its interior is connected to the water inlet mechanism to stabilize the water outlet pressure of the water outlet mechanism. The circulation component is installed on one side of the water outlet mechanism, and its two ends are respectively connected to the inside of the water outlet mechanism and the pressure stabilizing mechanism for circulating the medium inside the pump body.

[0006] Preferably, the water outlet mechanism includes an outlet pipe, inside which a turbine assembly is installed. The turbine assembly is fitted onto the outside of a drive shaft, which is connected to the output end of a drive motor inside the drive device. A check valve is installed at one top end of the outlet pipe, slidably connected to the top end of the outlet pipe, and a third spring is installed at the top of the check valve. By installing a turbine assembly inside the outlet pipe and fitting it onto the outside of the drive shaft, existing turbocharging technology allows the drive shaft to effectively transmit the power of the drive motor inside the drive device to the turbine assembly, thereby achieving stepwise pressurization of the medium. This turbocharging technology is widely used in the industrial field. Its principle is to compress and accelerate the fluid medium through the high-speed rotation of the turbine to increase the fluid pressure and flow rate. In this invention, the application of this technology significantly improves the outlet pressure and flow rate of the deep well submersible pump, enhances its conveying capacity, meets the high head and high flow rate requirements under complex working conditions such as deep wells, and ensures that oil or liquid media can be smoothly and efficiently extracted from deep wells and transported to the surface.

[0007] Meanwhile, the check valve is slidably connected to one end of the outlet pipe and equipped with a third spring. This allows it to remain open during normal water flow, ensuring smooth media output. In case of shutdown or abnormal conditions, the check valve quickly closes under the action of the third spring, preventing backflow of the media. This design not only avoids the impact and damage to the pump's internal structure caused by backflow, but also reduces energy waste due to backflow, improving the operational stability and reliability of the deep well submersible pump and extending the equipment's service life.

[0008] Preferably, the water inlet mechanism includes a lifting component, a cleaning component, and an inlet pipe. The lifting component is installed inside the inlet pipe and drives the cleaning component. The inlet pipe is internally connected to the pressure stabilizing mechanism. The cleaning component is installed outside the inlet pipe. A series of evenly spaced holes are formed on the bottom surface of the inlet pipe for water intake. By installing the lifting component inside the inlet pipe and using it to drive the external cleaning component, an automatic cleaning function for the inlet holes at the bottom of the inlet pipe is achieved. This design effectively solves the problem of water inlets in traditional deep-well submersible pumps being easily clogged by impurities. In actual operation, water flows through the holes at the bottom of the inlet pipe, driving the lifting component to move, which in turn drives the cleaning component to periodically clean the holes, preventing impurity accumulation and ensuring unobstructed flow in the inlet holes. Simultaneously, the inlet pipe is internally connected to the pressure stabilizing mechanism, ensuring the stability and uniformity of the water flow before entering the pump body, further improving the overall operating efficiency and stability of the deep-well submersible pump.

[0009] Preferably, the lifting assembly includes an impeller located outside the drive shaft. The bottom of the impeller is welded to the top end of a splined shaft. The splined shaft has a hollow interior. The outer wall of the splined shaft is slidably connected to the interior of the tubular structure at the top of the baffle plate. A first spring is fitted outside the splined shaft. The top end of the first spring is welded to the impeller, and the bottom end of the first spring is welded to the baffle plate. The baffle plate is in slidable contact with the outer wall of the drive shaft. A lifting block is provided at the bottom of the baffle plate, and the lifting block is rotatably connected to the bottom of the baffle plate. The impeller is located outside the drive shaft. When water flows through the inlet pipe, the power of the water flow drives the impeller to rotate. The rotation of the impeller is transmitted to the baffle plate through the splined shaft, causing it to rotate. Because the splined shaft has a hollow interior and its outer wall is slidably connected to the interior of the tubular structure at the top of the baffle plate, this structural design allows the baffle plate to move up and down under the action of the water flow. Meanwhile, the first spring is fitted onto the outside of the splined shaft and welded to both the impeller and the baffle plate, providing elastic support and a reset function for the movement of the baffle plate. When water flows through the inlet pipe, the kinetic energy of the water flow causes the baffle plate to experience significant resistance, thus pushing the baffle plate and the lifting block upwards. When the baffle plate rotates to the position aligned with the lifting block, the water flow resistance suddenly decreases, and the elastic force of the first spring causes the baffle plate and the lifting block to quickly reset downwards. This periodic up-and-down movement is transmitted through the connecting rod and scraper, achieving automatic cleaning of the inlet slot at the bottom of the inlet pipe.

[0010] Preferably, the cleaning assembly includes sealing plates symmetrically distributed on both sides of the outer wall of the water inlet pipe. The sealing plates are in close contact with and slide against the outer wall of the water inlet pipe. Two strip-shaped slots are symmetrically distributed on the outer wall of the water inlet pipe. The sealing plates are connected to the end of the lifting block by bolts. One bottom end of the sealing plate is fixedly connected to a connecting rod. The connecting rod is welded to multiple scrapers, each with a ring-shaped structure, and the scrapers slide against the outer wall of the water inlet pipe. The symmetrical distribution of the sealing plates on both sides of the outer wall of the water inlet pipe ensures close contact with and slides against the outer wall. This design ensures that the sealing plates closely follow the outer wall of the water inlet pipe during movement, thereby achieving effective coverage and cleaning of the water inlet slots. The connection of the sealing plates to the end of the lifting block by bolts not only ensures structural stability but also allows the sealing plates to move synchronously with the up-and-down movement of the lifting block. One bottom end of the sealing plate is fixedly connected to the connecting rod, which is welded to multiple scrapers. This allows the scrapers to move up and down through the linkage of the connecting rod and the sealing plates. The scraper has a ring-shaped structure and slides in contact with the outer wall of the water inlet pipe. This design allows the scraper to fully cover the water inlet groove at the bottom of the water inlet pipe, thereby achieving all-round cleaning of the groove.

[0011] Preferably, the pressure stabilizing mechanism includes a pressure stabilizing tube, one end of which is integrally formed with the inlet pipe. A pressure tube is installed inside the pressure stabilizing tube, and the bottom of the pressure tube has annularly spaced slots. A piston is installed inside the pressure tube, slidingly contacting the inner wall of the pressure tube, and a second spring is installed on the top of the piston. When water flows through the slots at the bottom of the pressure tube, the water pressure pushes the piston upward, compressing the second spring. This design allows the piston to move up and down according to changes in water pressure, thereby regulating the water pressure inside the pressure tube. When the water pressure inside the inlet pipe is unstable or the supply pressure is low, the second spring pushes the piston downward, allowing water at the top of the pressure tube to compensate downward, thus maintaining a stable water pressure flowing through the slots at the bottom of the pressure tube. This automatic adjustment mechanism effectively reduces fluctuations in water pressure and ensures stable outlet water pressure.

[0012] Preferably, a drive shaft is inserted inside the pressure tube. Two drive shafts are provided, and a first connecting block and a second connecting block are fixedly installed at the ends of the two drive shafts respectively. The first connecting block and the second connecting block are tightly fitted together and are both made of rubber. A pressure plate is rotatably connected to the top of the second connecting block. The two ends of the pressure plate are connected to the top of the pressure tube by fastening bolts. The connection between the two drive shafts is achieved by friction through the tight fit between the first connecting block and the second connecting block. When the system is overloaded, the lower drive shaft will rotate freely to prevent the drive shaft from being directly damaged by overload.

[0013] Preferably, the circulating component includes a circulating pipe, one bottom end of which is connected to a pressure stabilizing pipe, and one top end of which is connected to a water outlet pipe. A limiting ring is provided at the bottom end of the circulating pipe, welded to the inner wall of the circulating pipe. A connecting shaft is located inside the limiting ring, with a gap between the connecting shaft and the limiting ring. An end cap is welded to one end of the connecting shaft, and a hollow block is fitted onto the other end of the connecting shaft. A through hole is provided inside the hollow block for media flow, and a fourth spring is provided between the hollow block and the limiting ring. The connection between the bottom end of the circulating pipe and the top end to the water outlet pipe allows the water flow to form a closed circulation path within the pump body. When the water outlet or inlet becomes blocked, the water flow can return to the pressure stabilizing pipe through the circulating pipe, preventing equipment damage due to pressure buildup.

[0014] This invention provides a deep-well submersible oil pump with turbocharging function. It has the following beneficial effects: This deep-well submersible pump with turbocharging function operates by a drive motor within the drive unit that rotates the transmission shaft, thereby driving the turbine to progressively increase the pressure and output water from the top of the outlet pipe. As the water flows at high speed through the inlet pipe, it drives the impeller to rotate, which in turn drives the baffle plate to rotate via a splined shaft. When the baffle plate and the lifting block are misaligned, the water flow resistance increases, pushing the baffle plate and lifting block upwards, which in turn moves the sealing plate and scraper upwards. When the baffle plate rotates to align with the lifting block, the water flow resistance decreases, and the first spring pushes the lifting block and scraper downwards to reset. This allows the scraper to scrape up and down using the kinetic energy of the water flow, self-cleaning the bottom groove of the inlet pipe and effectively preventing blockage of the inlet hole. Simultaneously, after entering the pressure pipe, the water flows through the bottom groove and is discharged to the pressure stabilizing pipe. Due to the small flow area of ​​the groove, the water pressure in the pressure pipe increases, causing the water flow to lift the piston and compress the second spring. When the water pressure in the inlet pipe is unstable or the water supply pressure is low, the second spring pushes the piston downward, causing the water at the top of the pressure pipe to flow downward to compensate, maintaining a stable water flow pressure in the slot and reducing water flow pressure fluctuations, thereby effectively protecting the motor.

Detailed Implementation

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0018] Example 1: Please refer to Figure 1-7 This invention provides a technical solution: a deep well submersible oil pump with turbocharging function, comprising: a drive unit 1, which has an internal motor for providing power; and a water outlet mechanism 4, which has an internal turbine assembly 403 connected to the drive unit 1 for conveying a medium; a water inlet mechanism 2, installed on the top of the drive unit 1; a pressure stabilizing mechanism 3, located on the top of the water inlet mechanism 2 and internally connected to the water inlet mechanism 2 for stabilizing the water outlet pressure of the water outlet mechanism 4; and a circulation component 5, installed on one side of the water outlet mechanism 4 and with both ends connected to the interior of the water outlet mechanism 4 and the pressure stabilizing mechanism 3 respectively, for circulating the medium inside the pump body. First, by incorporating a specialized cleaning component, this deep-well submersible pump effectively prevents impurities from accumulating at the inlet. This design utilizes the kinetic energy of the water flow to drive the cleaning component to automatically clean the inlet at the bottom of the inlet pipe 207, thereby preventing blockage and ensuring the normal operation and efficiency of the deep-well submersible pump. Second, through the synergistic effect of the pressure stabilizing mechanism 3 and the circulation component 5, this deep-well submersible pump effectively reduces fluctuations in water pressure. The pressure stabilizing mechanism 3 can stabilize the outlet water pressure, maintaining a stable outlet water pressure even when the inlet water pressure is unstable.

[0019] Example 2: Please refer to Figure 1-7This invention provides a technical solution: the water outlet mechanism 4 includes a water outlet pipe 405, a turbine assembly 403 is installed inside the water outlet pipe 405, the turbine assembly is mounted on the outside of a drive shaft 404, the drive shaft 404 is connected to the output end of a drive motor inside the drive device 1, a check valve 402 is installed at one top end of the water outlet pipe 405, the check valve 402 is slidably connected to one top end of the water outlet pipe 405, and a third spring 401 is installed at the top of the check valve 402; the water inlet mechanism 2 includes a lifting assembly. The components include a cleaning assembly and a water inlet pipe 207. A lifting assembly is installed inside the water inlet pipe 207 to drive the cleaning assembly. The water inlet pipe 207 is internally connected to the pressure stabilizing mechanism 3. The cleaning assembly is installed outside the water inlet pipe 207. The bottom end of the water inlet pipe 207 has evenly spaced holes and slots for water intake. The lifting assembly includes an impeller 201, located outside the drive shaft 404. The bottom of the impeller 201 is welded to the top end of a splined shaft 202. The splined shaft 202 has a hollow interior. The structure includes a splined shaft 202 whose outer wall is slidably connected to the inner tubular structure at the top of the baffle plate 204; a first spring 203 is fitted outside the splined shaft 202; one top end of the first spring 203 is welded to the impeller 201, and one bottom end of the first spring 203 is welded to the baffle plate 204; the baffle plate 204 is in slidable contact with the outer wall of the drive shaft 404; a lifting block 205 is provided at the bottom of the baffle plate 204, and the lifting block 205 is rotatably connected to the bottom of the baffle plate 204; the cleaning assembly includes a sealing plate 206. The sealing plates 206 are symmetrically distributed on both sides of the outer wall of the water inlet pipe 207. The sealing plates 206 are tightly fitted and slidingly contacted with the outer wall of the water inlet pipe 207. Two strip-shaped holes and grooves are symmetrically distributed on the outer wall of the water inlet pipe 207. The sealing plates 206 are connected to the end of the lifting block 205 by bolts. One bottom end of the sealing plates 206 is fixedly connected to the connecting rod 208. The connecting rod 208 is welded to multiple scrapers 209. The scrapers 209 have a ring-shaped structure and slide in contact with the outer wall of the water inlet pipe 207. In this embodiment, when the device is in use, the drive motor inside the drive unit 1 drives the transmission shaft 404 to rotate. Simultaneously, the rotation of the transmission shaft 404 drives the turbine to perform step-by-step pressurization, thereby outputting water from the top end of the outlet pipe 405. During the high-speed flow of water inside the inlet pipe 207, the water drives the impeller 201 to rotate, which in turn drives the baffle plate 204 to rotate via the spline shaft 202. This causes the baffle plate 204 to be misaligned with the top of the lifting block 205, resulting in greater water flow resistance on the baffle plate 204. The water flow can push the baffle plate 204 and the lifting block 205 upward, which in turn can drive the scraper 209 upward through the sealing plate 206. When the baffle plate 204 rotates to align with the lifting block 205, the water flow resistance on the baffle plate 204 will suddenly decrease. Then, under the pushing mechanism of the first spring 203, the lifting block 205 and the scraper 209 can be reset downward, so that the scraper 209 can use the kinetic energy of the water flow to achieve the effect of scraping up and down to clean the bottom hole groove of the water inlet pipe 207, which helps to avoid the blockage of the bottom water inlet hole of the water inlet pipe 207.

[0020] Example 3: Please refer to Figure 1-7 This invention provides a technical solution: a pressure stabilizing mechanism 3 includes a pressure stabilizing tube 301, one end of which is integrally formed with the water inlet pipe 207. A pressure tube 302 is disposed inside the pressure stabilizing tube 301. The bottom of the pressure tube 302 has annularly spaced grooves. A piston 303 is disposed inside the pressure tube 302, slidingly contacting the inner wall of the pressure tube 302. A second spring 304 is disposed on the top of the piston 303. A drive shaft 404 is inserted inside the pressure tube 302. Two drive shafts 404 are provided, and a first connecting block 305 and a second connecting block 306 are respectively fixedly installed at the ends of the two drive shafts 404. The first connecting block 305 and the second connecting block 306 are tightly fitted together, and both the first connecting block 305 and the second connecting block 306 are made of rubber. A pressure plate 307 is rotatably connected to the top of the connecting block 306. Both ends of the pressure plate 307 are connected to the top of the pressure pipe 302 by fastening bolts 308. The circulation component 5 includes a circulation pipe 501. One end of the circulation pipe 501 is connected to the pressure stabilizing pipe 301, and one end of the circulation pipe 501 is connected to the outlet pipe 405. A limit ring 503 is provided at one end of the circulation pipe 501. The limit ring 503 is welded to the inner wall of the circulation pipe 501, and a connecting shaft 506 is provided inside the limit ring 503. There is a gap between the connecting shaft 506 and the limit ring 503. An end cap 505 is welded to one end of the connecting shaft 506, and a hollow block 502 is fitted on the other end of the connecting shaft 506. A through hole is provided inside the hollow block 502 for medium flow, and a fourth spring 504 is provided between the hollow block 502 and the limit ring 503. In this embodiment, after water flows into the pressure pipe 302 through the inlet pipe 207, it is discharged into the pressure stabilizing pipe 301 through the groove at the bottom of the pressure pipe 302. Because the flow surface of the groove at the bottom of the pressure pipe 302 is small, the water pressure inside the pressure pipe 302 is relatively high, allowing the water to push the piston 303 upwards. Simultaneously, the piston 303 compresses the second spring 304. When the water pressure inside the inlet pipe 207 is unstable or the supply pressure is low, the second spring 304 will push downwards, thus allowing water at the top of the pressure pipe 302 to flow upwards. The pressure is reduced to keep the water pressure flowing through the slot at the bottom of the pressure pipe 302 stable. This reduces pressure fluctuations and helps protect the motor. When the inlet or outlet is blocked, the turbine will continue to rotate, allowing the water inside to enter the top of the circulation pipe 501. The water inside the circulation pipe 501 will then push open the bottom end cover 505 and flow back into the pressure stabilizing pipe 301, thus achieving water circulation within the pump body. This helps prevent pressure increase and motor damage caused by inlet or outlet blockage.
