Description

Technical Field

[0001] This utility model belongs to the technical field of submersible pump launch and recovery devices, and in particular relates to a horizontal launch and recovery device for submersible pumps in shallow water areas. Background Technology

[0002] To prevent collisions with underwater obstacles or damage to the equipment itself, and to reduce interference from mud, weeds, and other impurities in shallow water, submersible pumps must always be kept in a horizontal position when operating in shallow water.

[0003] Due to the large weight of submersible pumps, the launching and retrieval of submersibles in existing diving areas are mostly accomplished using cranes. The crane hook is attached to the lifting point of the submersible pump before it is submerged in the water. However, it is difficult to ensure that the submersible pump remains horizontal when operating with a single hook.

[0004] Therefore, we need to design a horizontal deployment and retrieval device for submersible pumps in shallow water areas to solve these problems. Utility Model Content

[0005] The problem to be solved by this utility model is to provide a horizontal launching and retracting device for submersible pumps in shallow water areas.

[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A horizontal launching and retracting device for a submersible pump in shallow water includes a base plate with a set of relatively parallel support plates on the base plate. A drum is rotatably mounted between the two support plates, and two sets of steel cables are wound on the drum. A connecting plate is fixedly mounted on the two support plates, and a drive screw and an upper sliding rod are mounted between the two connecting plates. A sliding frame is mounted on the upper sliding rod and the drive screw. An upper guide wheel is mounted on the top of the sliding frame, and a lower guide wheel is mounted on the bottom of the sliding frame. The upper guide wheel is parallel to the axis of the drum, and the axis of the lower guide wheel is perpendicular to the axis of the upper guide wheel. A transition wheel is mounted between the upper and lower guide wheels. One set of steel cables passes over the top of the upper guide wheel, and the other set of steel cables passes over the top of the upper guide wheel and then passes over the bottom of the transition wheel and the top of the lower guide wheel in sequence.

[0007] Preferably, a speed reducer is fixedly installed on one of the support plates, the output end of the speed reducer is fixedly connected to one end of the drum, and a motor is fixedly installed on the input end of the speed reducer.

[0008] With this setup, the motor provides the basic power for the device, while the reducer can reduce speed and increase torque, converting the high speed and low torque of the motor into the low speed and high torque required by the drum. This satisfies the traction requirements of the submersible pump while preventing the motor from being damaged due to excessive load. At the same time, the reducer can buffer the instantaneous power fluctuations of the motor, making the drum rotation speed more stable and preventing the submersible pump from shaking violently due to sudden changes in the winding and unwinding speed, thus improving operational safety.

[0009] Preferably, a drive wheel is rotatably mounted on another support plate, the drive wheel being fixedly connected to the drum, and a driven wheel is rotatably mounted on an adjacent connecting plate, the driven wheel being fixedly connected to the drive screw, and the drive wheel and the driven wheel are connected by a transmission belt, and a protective cover is also mounted on the outside of the drive wheel and the driven wheel.

[0010] This setup not only utilizes the rotation of the drum itself to drive the drive wheel, which in turn drives the driven wheel and drive screw to rotate synchronously via the transmission belt, achieving mechanical synchronization of the sliding frame movement during drum winding and unwinding, eliminating the need for an additional power source, thus saving equipment costs and avoiding the delay issues of electronic synchronization. It also ensures precise matching between the sliding frame position and the length of the cable winding and unwinding, preventing uneven wear on the cable. Secondly, the protective cover effectively isolates impurities such as mud, sand, and weeds in shallow water areas, while preventing external collisions from damaging the drive wheel, driven wheel, and transmission belt. This protects the transmission mechanism from corrosion, extends its service life, and ensures the long-term stability of synchronous transmission.

[0011] Preferably, a brake disc is also provided between the drum and one of the support plates. The brake disc is fixedly connected to the drum. Several support bars are fixedly provided inside the brake disc. The outside of the brake disc is covered with brake pads. A fixed seat is provided on the base plate below the brake disc. A brake cylinder is hinged to the fixed seat. One end of the brake pad is hinged to the fixed seat, and the other end is hinged to the output end of the brake cylinder.

[0012] This design enables the drum to have a reliable braking function. When the submersible pump is retracted to the designated position, the brake cylinder can push the brake pads to clamp the brake disc, forcing the drum to stop rotating through friction. This prevents the drum from reversing due to the weight of the submersible pump, avoids accidental slippage of the submersible pump, and ensures safety in shallow water operations. The support bars inside the brake disc also enhance its structural strength, preventing the brake disc from deforming due to excessive force during braking and ensuring stable braking performance. Finally, the brake pads adopt an external design, which not only provides a large contact area and good braking performance, but also makes it easy to replace them individually after wear, reducing maintenance costs and difficulty.

[0013] Preferably, a lower slide rod is fixedly installed on the base plate below the upper slide rod, the axis of the lower slide rod is parallel to the upper slide rod, the sliding frame is slidably connected to the lower slide rod, and the lower guide wheel is located between the upper slide rod and the lower slide rod.

[0014] This configuration, with the sliding frame working in conjunction with both the upper and lower sliding rods to form a two-point support structure, significantly improves the stability of the sliding frame compared to a single sliding rod support. It prevents tilting and swaying during sliding and ensures precise guiding positions of the upper and lower guide wheels. Furthermore, the lower guide wheel, positioned between the two sliding rods, makes the cable guiding path more compact, effectively reducing the overall size of the device and adapting to the limited installation space in shallow water areas. The lower sliding rod can share the tension transmitted by the sliding frame and the cable, reducing the load on the upper sliding rod and preventing long-term deformation of a single sliding rod, thus extending the service life of the sliding rod components.

[0015] Preferably, an upper limit tube and a lower limit tube are also fixedly installed on the sliding frame. The upper limit tube is located between the upper guide wheel and the lower guide wheel. A wire groove is formed on the side wall of the upper limit tube. The transition wheel is rotatably installed in the wire groove. The bottom of the transition wheel and the top of the lower guide wheel are located in the same horizontal plane. The lower limit tube is located below the upper limit tube and is coaxial with the upper limit tube.

[0016] This configuration allows the upper limit tube to fix the position of the transition wheel through the cable groove, preventing it from shifting during rotation. It also provides auxiliary limiting for the steel cable, preventing it from falling off the transition wheel. The tops of the transition wheel and the lower guide wheel are kept at the same level, ensuring that there is no height difference in the direction of the steel cable from the transition wheel to the lower guide wheel, reducing bending stress and friction loss, and further protecting the steel cable. The coaxial upper and lower limit tubes guide and limit the steel cable, preventing parts from getting tangled or colliding with the device during the winding and unwinding process, ensuring smooth overall operation.

[0017] Preferably, there are two upper guide wheels, and the two sets of steel cables pass over the two upper guide wheels respectively.

[0018] This configuration allows for independent guidance of each cable via two upper guide wheels, preventing the two sets of steel cables from tangling and rubbing on the same guide wheel. This significantly reduces wear between the cables and extends their service life. Independent guidance also ensures more even force distribution on the two sets of steel cables, guaranteeing consistent traction at both ends of the submersible pump. During deployment and retrieval, the submersible pump remains horizontal, preventing it from tilting and colliding with the bottom or sidewalls of shallow water areas, thus protecting the submersible pump equipment.

[0019] Preferably, two support seats are fixedly provided on the base plate, the sliding rod is located between the two support seats, and both ends are connected to the support seats respectively.

[0020] This configuration provides a stable mounting base for the sliding rod, preventing deformation or displacement due to sliding of the sliding frame or tension of the steel cable. This ensures the stability of the sliding rod's axis and thus guarantees smooth sliding of the sliding frame. The symmetrical distribution of the two support bases makes the force on the sliding rod more even, enhancing its support strength and adapting to the long-term stress requirements of the device. The support bases also facilitate the installation and disassembly of the sliding rod, eliminating the need to disassemble the entire device for later maintenance, thus reducing maintenance difficulty and cost.

[0021] The advantages and positive effects of this utility model are: This utility model provides a stable foundation for the equipment through the base plate, a set of parallel support plates provides rotational support for the drum, and the drum can achieve two-point traction of the submersible pump by winding two sets of steel cables; the connecting plate provides a fixed carrier for the drive screw and the upper slide rod, and the sliding frame, together with the upper slide rod and the drive screw, realizes position adjustment. The upper guide wheel and the lower guide wheel form a complementary guiding structure through the vertical axis design.

[0022] Two sets of differently wound steel cables are set on the upper guide wheel and the lower guide wheel. This not only uses the two-point traction of the two sets of steel cables to balance the force on the submersible pump, but also avoids the submersible pump tilting or shifting during the retrieval and deployment process, adapting to the requirements of the submersible pump's horizontal posture in shallow water areas. The upper guide wheel is parallel to the axis of the drum, which ensures that the steel cable does not shift laterally when it is drawn out of the drum, ensuring that the steel cable is wound evenly and preventing knots; the lower guide wheel is perpendicular to the axis of the upper guide wheel, which can flexibly change the direction of the steel cable and accurately adapt to the path requirements of the submersible pump for horizontal deployment and retraction.

[0023] The transition wheel allows the steel cable to turn more smoothly between the upper and lower guide wheels, significantly reducing frictional loss between the steel cable and the guide wheels and extending the service life of the steel cable. The drive screw can move the sliding frame and adjust the position of the upper and lower guide wheels according to the position of the steel cable on the drum, ensuring that the steel cable is always in a stable guiding state and further improving the stability of winding and unwinding.

[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly.

Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0029] The present invention will be further described below with reference to the accompanying drawings: Example 1: As Figures 1-5As shown, a horizontal deployment and retraction device for a submersible pump in shallow water includes a base plate 1. A set of relatively parallel support plates 2 are mounted on the base plate 1. A drum 5 is rotatably mounted between the two support plates 2, and two sets of steel cables 9 are wound on the drum 5. To achieve stable traction of the submersible pump, the two sets of steel cables 9 are respectively connected to two stress points of the submersible pump. Connecting plates 22 are also fixedly mounted on the two support plates 2, forming a vertical fixed structure with the support plates 2, providing an installation reference for subsequent components. A drive screw 8 and an upper sliding rod 7 are arranged between the two connecting plates 22. The drive screw 8 provides the moving power for the sliding frame 16, and the upper sliding rod 7 provides horizontal support for the sliding frame 16. The guide is provided by a sliding frame 16 on the upper slide rod 7 and the drive screw 8. The sliding frame 16 can move along the axis of the upper slide rod 7 and the drive screw 8. An upper guide wheel 15 is provided at the top of the sliding frame 16, and a lower guide wheel 17 is provided at the bottom of the sliding frame 16. The upper guide wheel 15 is parallel to the axis of the drum 5, ensuring that the steel cable 9 can pass around the upper guide wheel 15 in a horizontal direction after being led out of the drum 5. The axis of the lower guide wheel 17 is perpendicular to the upper guide wheel 15, used to change the direction of the steel cable 9 to adapt to the horizontal winding and unwinding path of the submersible pump. A transition wheel 21 is also provided between the upper guide wheel 15 and the lower guide wheel 17. The transition wheel 21 is used to connect the upper guide wheel 15 and the lower guide wheel 17 to meet the turning requirements. Figure 4 As shown, one set of steel cables 9 passes over the top of the upper guide wheel 15 and directly pulls the submersible pump in the horizontal direction. The other set of steel cables 9 passes over the top of the upper guide wheel 15 several times, and then passes over the bottom of the transition wheel 21 and the top of the lower guide wheel 17 in sequence. Through the turning of the transition wheel 21 and the lower guide wheel 17, the two sets of steel cables 9 finally form a synchronous horizontal traction force.

[0030] A reducer 3 is fixedly installed on one of the support plates 2, and the support plate 2 provides fixed support for the reducer 3. The output end of the reducer 3 is fixedly connected to one end of the drum 5 to transmit power to the drum 5. A motor 4 is fixedly installed at the input end of the reducer 3 to provide initial power to the device. After the motor 4 starts, the power is transmitted to the drum 5 through the reducer 3. The reducer 3 converts the high speed and low torque of the motor 4 into the low speed and high torque required by the drum 5 through the speed reduction and torque increase action to meet the torque requirements of the submersible pump traction, while avoiding damage to the motor 4 due to excessive load. Finally, it drives the drum 5 to rotate in both directions to realize the winding and unwinding of the steel cable 9.

[0031] like Figure 3As shown, a drive wheel 25 is rotatably mounted on another support plate 2. The drive wheel 25 is fixedly connected to the drum 5. When the drum 5 rotates, it can synchronously drive the drive wheel 25 to rotate. A driven wheel 27 is rotatably mounted on an adjacent connecting plate 22. The connecting plate 22 provides rotational support for the driven wheel 27. The driven wheel 27 is fixedly connected to the drive screw 8. When the driven wheel 27 rotates, it can directly drive the drive screw 8 to rotate synchronously. The drive wheel 25 and the driven wheel 27 are connected by a transmission belt 26. This allows the drive screw 8 to rotate synchronously while the drum 5 is winding up and unwinding the steel cable 9, thereby moving the sliding frame 16. A protective cover 23 is also fitted on the outside of the drive wheel 25 and the driven wheel 27. The protective cover 23 covers the transmission belt 26, the drive wheel 25, and the driven wheel 27 to prevent mud, sand, and aquatic plants in shallow water from entering the transmission structure and affecting the transmission efficiency. It also prevents exposed components from causing safety hazards.

[0032] like Figure 2 As shown, a brake disc 11 is also provided between the drum 5 and one of the support plates 2. The brake disc 11 is fixedly connected to the drum 5. When the drum 5 rotates, it synchronously drives the brake disc 11 to rotate. Several support bars 12 are fixedly provided inside the brake disc 11. The support bars 12 are radially distributed along the brake disc 11 to enhance the structural strength of the brake disc 11 and prevent the brake disc 11 from deforming during braking. The outer side of the brake disc 11 is covered with brake pads 10. When the brake pads 10 come into contact with the brake disc 11, friction is generated. A fixing seat 24 is provided on the base plate 1 below the brake disc 11. The base plate 1 is a fixed seat. The base 24 provides a fixed foundation, and the brake cylinder 13 is hinged on the fixed base 24. The fixed base 24 provides rotational support for the brake cylinder 13. One end of the brake pad 10 is hinged to the fixed base 24, and the other end is hinged to the output end of the brake cylinder 13. When braking is required, the output end of the brake cylinder 13 shortens, pulling one end of the brake pad 10, causing the brake pad 10 to clamp the brake disc 11. The friction prevents the brake disc 11 from rotating, thereby stopping the drum 5 from rotating and locking the steel cable 9. When the brake cylinder 13 retracts, the brake pad 10 separates from the brake disc 11, and the drum 5 resumes its rotational ability.

[0033] A lower slide bar 6 is fixedly installed on the base plate 1 below the upper slide bar 7. The base plate 1 provides fixed support for the lower slide bar 6. The axis of the lower slide bar 6 is parallel to the upper slide bar 7, ensuring that the sliding frame 16 can move in the same horizontal direction. The sliding frame 16 is slidably connected to the lower slide bar 6. The lower slide bar 6 and the upper slide bar 7 together provide bidirectional support for the sliding frame 16, preventing the sliding frame 16 from tilting when it moves. The lower guide wheel 17 is located between the upper slide bar 7 and the lower slide bar 6, so that the guide path of the lower guide wheel 17 is within the support range of the sliding frame 16, ensuring the stability of the steel cable 9 during traction, while compressing the overall space of the device.

[0034] An upper limit tube 19 and a lower limit tube 18 are also fixedly installed on the sliding frame 16. The sliding frame 16 provides a fixed foundation for both. The upper limit tube 19 is located between the upper guide wheel 15 and the lower guide wheel 17 and is used to limit the installation position of the transition wheel 21. A cable groove 20 is opened on the side wall of the upper limit tube 19. The cable groove 20 is used to limit the movement path of the steel cable 9 and prevent the steel cable 9 from falling off the transition wheel 21. The transition wheel 21 is rotatably set in the cable groove 20, and the bottom of the transition wheel 21 and the top of the lower guide wheel 17 are located in the same horizontal plane to ensure that there is no height difference when the steel cable 9 turns from the transition wheel 21 to the lower guide wheel 17, thereby reducing the bending stress of the steel cable 9. The lower limit tube 18 is located below the upper limit tube 19 and is coaxial with the upper limit tube 19. The upper limit tube 19 and the lower limit tube 18 are used to pass through the submersible pump cable or water pipe to avoid it from getting tangled with the steel cable 9 and the guide wheel, and to ensure smooth winding and unwinding.

[0035] like Figure 5 As shown, there are two upper guide wheels 15, and two sets of steel cables 9 pass over the two upper guide wheels 15 respectively; the two upper guide wheels 15 correspond one-to-one with the two sets of steel cables 9, and each set of steel cables 9 is guided independently by one upper guide wheel 15, so as to avoid the two sets of steel cables 9 crossing and rubbing on the same guide wheel, and at the same time ensure that the traction direction of the two sets of steel cables 9 is consistent, so that the force at both ends of the submersible pump is even, and to prevent the submersible pump from tilting during the retraction and deployment.

[0036] Two support seats 14 are fixedly installed on the base plate 1. The base plate 1 provides a fixed foundation for the support seats 14. The sliding rod 6 is located between the two support seats 14, and its two ends are connected to the support seats 14 respectively. The support seats 14 provide fixed support at both ends for the sliding rod 6, so as to prevent the sliding rod 6 from deforming due to the sliding of the sliding frame 16 or the tension of the steel cable 9, ensuring the stability of the axis of the sliding rod 6, thereby ensuring the sliding accuracy of the sliding frame 16, and enhancing the load-bearing capacity of the sliding rod 6.

[0037] The working process of this embodiment is as follows: When in use, the base plate 1 is fixed with anchor bolts to ensure overall stability; the two lifting points of the submersible pump are respectively connected to the ends of the two sets of steel cables 9 on the drum 5. The submersible pump cable and water supply pipe pass through the upper limit pipe 19 and the lower limit pipe 18 in sequence to avoid entanglement with the steel cables 9 and guide wheels during winding and unwinding; the brake cylinder 13 is in the retracted state, the brake pad 10 is separated from the brake disc 11, and the drum 5 can rotate freely; the sliding frame 16 is initially close to the connecting plate 22, and the upper guide wheel 15, the transition wheel 21, and the lower guide wheel 17 are in the preset guide position. The two sets of steel cables 9 are respectively attached to the corresponding upper guide wheel 15. One set of steel cables 9 extends directly along the upper guide wheel 15 to the submersible pump, and the other set of steel cables 9 extends to the submersible pump after turning through the bottom of the transition wheel 21 and the top of the lower guide wheel 17. Both sets of steel cables 9 are in a slightly tensioned state.

[0038] Next, start motor 4. Motor 4 outputs high-speed rotational power, which is transmitted through the input end of reducer 3. Reducer 3 reduces speed and increases torque through internal gear set, converting high speed and low torque into low speed and high torque required by drum 5. Then, it is transmitted to drum 5 through the output end of reducer 3, driving drum 5 to rotate in the direction of releasing steel cable 9.

[0039] When the drum 5 rotates, the two sets of steel cables 9 are released synchronously from the drum 5, driving the submersible pump to move horizontally towards the shallow water area. Simultaneously, the rotation of the drum 5 synchronously drives the drive wheel 25, which is fixed to it, to rotate. The drive wheel 25 drives the driven wheel 27 to rotate via the transmission belt 26. The driven wheel 27, in turn, drives the drive screw 8, which is fixed to it, to rotate synchronously. When the drive screw 8 rotates, it engages with the internal thread of the sliding frame 16. Because the sliding frame 16 simultaneously slides with the upper sliding rod 7 and the lower sliding rod 6, it moves along the axis of the sliding rods, ensuring that the steel cables 9 remain in contact with the upper guide wheel 15, the transition wheel 21, and the lower guide wheel 17 during release, preventing the steel cables 9 from slackening, sagging, or shifting. The synchronous traction of the two sets of steel cables 9 keeps the submersible pump in a horizontal position. The lower guide wheel 17 is located between the upper sliding rod 7 and the lower sliding rod 6. The double sliding rod support prevents the sliding frame 16 from tilting, further ensuring the stability of the steel cable 9's guidance and ensuring that the submersible pump remains horizontal throughout the deployment and retraction process.

[0040] The above description details one embodiment of the present utility model, but it is merely a preferred embodiment and should not be construed as limiting the scope of the present utility model. All equivalent variations and improvements made within the scope of the present utility model application should still fall within the patent coverage of the present utility model.
