Description

A floating vortex suction cup device suitable for resisting high-speed water flow Technical Field

[0001] This invention belongs to the field of underwater suction cup technology, and in particular relates to a floating vortex suction cup device suitable for resisting high-speed water flow. Background Technology

[0002] Large underwater structures such as reservoir dams, bridge piers, and large underwater pipelines are prone to problems such as concrete cracks and steel corrosion during use due to long-term water erosion and other geological disasters. If they are not maintained regularly, they will seriously threaten the overall safety of the structure. Therefore, the inspection of underwater structures is essential.

[0003] However, inspecting underwater structures in use, especially those in complex waterways and high-velocity environments, remains challenging. In complex water flow environments, the robot body struggles to maintain stability under the impact of the current. Simultaneously, underwater propulsion devices are easily disturbed by the current, resulting in highly unstable power output, making robot operation in complex water flow environments extremely difficult. Currently, very few underwater machines can adapt to high-current environments. Most machines operating in high-current conditions rely on increasing the power of their underwater propulsion devices to resist the impact of the current, which not only increases the size of the robot body but also leads to a certain degree of energy waste. Furthermore, underwater engineering often occurs in complex and variable underwater environments; factors such as current intensity and surface roughness pose challenges to adsorption performance. Traditional technologies may exhibit limitations and shortcomings in these special environments. Summary of the Invention

[0004] In order to solve the problems existing in the background art, the purpose of the present invention is to provide a floating vortex suction cup device suitable for resisting high-speed water flow.

[0005] The technical solution adopted in this invention is as follows:

[0006] The device includes a DC motor, a vortex suction cup, a microneedle adsorption unit, a flow field protection unit, and a floating vortex unit. The flow field protection unit is sleeved on the outside of the vortex suction cup. The microneedle adsorption unit is fixedly installed on the outer wall of the flow field protection unit, and the lower surfaces of the flow field protection unit and the microneedle adsorption unit are flush. The floating vortex unit is fixedly installed on the upper surface of the flow field protection unit. The outer shell of the vortex suction cup is fixedly connected to the pin pressure plate in the floating vortex unit. The pin pressure plate is used to limit the amplitude of the vortex suction cup's up and down floating in the water. The output shaft of the DC motor is connected to the vortex blades in the vortex suction cup to drive the vortex blades of the vortex suction cup to rotate, thereby forming a flow field in the water, and then achieving adsorption on the wall surface to be adsorbed through the water flow field.

[0007] The flow field protection unit includes an annular flow barrier, an annular sealing ring, and a sealing ring fixing ring. The swirling suction cup is movably disposed inside the flow barrier, with the outer wall of the swirling suction cup shell in contact with the inner wall of the flow barrier. The sealing ring and the sealing ring fixing ring are both fixedly installed on the lower surface of the flow barrier by a microneedle adsorption unit. The sealing ring is sealed and fitted on the outer surface of the sealing ring fixing ring, and the lower surfaces of the sealing ring and the sealing ring fixing ring are flush. When the swirling suction cup device adsorbs the wall surface to be adsorbed, the swirling blades of the swirling suction cup rotate under the drive of a DC motor. When the sealing ring contacts the wall surface to be adsorbed, the shell of the swirling suction cup, the flow barrier connected to the swirling suction cup, the sealing ring, and the wall surface to be adsorbed form a closed negative pressure water chamber, so that the swirling suction cup device achieves adsorption of the wall surface to be adsorbed under the negative pressure of the closed negative pressure water chamber.

[0008] The floating swirl unit includes an annular pin pressure plate, a pin positioning rod, and a spring pin; a ring of pin positioning rods is fixedly installed on the outer periphery of the upper surface of the flow deflector, and the spring pin is sleeved on the outer side wall of the pin positioning rod. The pin pressure plate and the flow deflector are arranged parallel to each other and spaced apart, with the pin pressure plate located above the flow deflector. The bottom and top ends of the spring pin are connected to the flow deflector and the pin pressure plate, respectively, so that the pin pressure plate can be moved up and down on the flow deflector through the spring pin.

[0009] The pin plate and the outer shell of the vortex suction cup are fixedly connected. When the vortex suction cup moves up and down under the impact of external water flow, the vortex suction cup drives the pin plate to move up and down along the axis of the spring pin. The elastic force of the spring in the spring pin buffers the movement of the vortex suction cup in the up and down direction, preventing the vortex suction cup device from detaching from the wall to be adsorbed.

[0010] The microneedle adsorption unit mainly consists of a microneedle fixing ring and several microneedles. A ring of microneedles is fixedly installed on the outer wall of the microneedle fixing ring. The sealing ring and the sealing ring fixing ring are both installed on the lower surface of the microneedle fixing ring. The microneedles are located outside the sealing ring, and the lower surface of the tip of the microneedle is flush with the lower surface of the sealing ring. When the sealing ring contacts the wall surface to be adsorbed, the microneedles penetrate the wall surface to be adsorbed. The lateral friction between the microneedles and the wall surface to be adsorbed achieves reliable adsorption between the vortex suction cup device and the wall surface to be adsorbed.

[0011] The top of the inner wall of the sealing ring fixing ring is provided with a ring of rectangular protrusions. The rectangular protrusions are mainly formed by several downward-facing rectangular protrusions evenly spaced along the circumference of the sealing ring fixing ring. The bottom of the inner wall of the sealing ring fixing ring is provided with a ring of rectangular flanges. The rectangular flanges are mainly formed by several inward-facing rectangular flanges evenly spaced along the circumference of the sealing ring fixing ring. The rectangular protrusions and rectangular flanges are located in the same circumferential direction, and the rectangular protrusions and rectangular flanges are arranged alternately along the circumference. When water flows into the vortex suction cup device, the rectangular protrusions and rectangular flanges are used to buffer the water flow to prevent excessive water flow from disrupting the flow field inside the vortex suction cup device.

[0012] The top of the pin positioning rod is fitted with a limiting bolt, and the pin pressure plate is limited below the limiting bolt to prevent the pin pressure plate from falling off, thereby limiting the displacement of the swirling suction cup in the vertical direction.

[0013] The outer wall of the flow deflector is inclined to reduce the impact of underwater water flow on the vortex suction cup device. The inclination angle of the outer wall of the flow deflector ranges from 30 degrees to 45 degrees.

[0014] When the swirling suction cup device adsorbs the wall surface to be adsorbed, the distance between the swirling blades in the swirling suction cup and the wall surface to be adsorbed is no more than 20mm.

[0015] A microneedle fixing ring fixes several microneedles at equal intervals around the circumference. The microneedle fixing ring is fixedly connected to the flow baffle above. The flow baffle has holes vertically opened around the circumference for fixing spring pins. The spring pin is sleeved on the pin positioning rod. The spring pin can move up and down on the outer wall of the pin positioning rod. The spring pin is fixedly connected to the pin pressure plate. The pin pressure plate is fixedly connected to the servo motor. Therefore, the vortex suction cup can move up and down synchronously with the pin pressure plate.

[0016] The microneedle retaining ring has a sealing ring embedded inside. The sealing ring is in clearance fit with the cyclone suction cup. A sealing ring is nested outside the sealing ring to increase the airtightness of the internal flow field during the adsorption process.

[0017] As shown in Figure 6, the figure represents the elastic force generated by the spring pin; the reaction force generated by the spring pin; the upward force generated by external disturbance; the damping force generated by the flow field protection; the adsorption force generated by the suction cup; the gap between the suction cup and the wall; the vertical movement speed of the suction cup against the wall; and V represents the cavity volume. Compared with traditional underwater vortex suction cups, the device of this invention can achieve stable adsorption of the suction cup in high-velocity underwater environments. Simultaneously, the floating vortex suction cup device ensures stability even after the suction cup has moved a certain distance from the wall, and the increase in the suction cup gap when the suction cup device is not removed from the wall has almost no impact on the suction force. Furthermore, through the circumferentially installed microneedle array, micro-damage can be caused by the microneedles piercing the wall during the initial stage of adsorption, embedding themselves in the wall and increasing the suction cup's resistance to lateral friction from high-speed water flow.

[0018] When the suction cup is propelled away from the wall by external force, the volume of the cavity inside the suction cup rapidly increases, causing the internal pressure to decrease. Under the action of the internal and external pressure difference, a downward force is generated. This force has a resisting effect on the external force, preventing the suction cup gap from increasing further. This phenomenon is defined as the damping characteristic of the suction cup. The generation of damping force allows the suction cup to adapt to the impact load of water flow in complex flow velocity environments. Even if a load much greater than the suction force of the suction cup is applied, it will not cause the suction cup to detach from the wall, avoiding the problem of sudden suction cup failure due to excessive load.

[0019] The beneficial effects of this invention are as follows:

[0020] 1. The device of the present invention greatly improves the suction force of the suction cup in a high flow rate environment by sealing the sealing ring, and reduces the power consumption of the suction cup.

[0021] 2. The device of the present invention ensures that it remains stable even after the suction cup is a certain distance away from the wall. When the protection device is not removed from the wall, the increase in the gap between the suction cups has almost no impact on the suction force. This avoids the problem of suction failure caused by the suction cup leaving the wall due to a sudden increase in load. Moreover, the maximum protection gap is the stroke of the spring pin, and safe adsorption can be guaranteed within 20mm of the suction cup leaving the wall.

[0022] 4. The device of the present invention is equipped with a microneedle array. When the suction cup is adsorbed, the compressed spring pin is brought to its limit position, which applies positive pressure to the microneedle and then pierces into the wall surface, causing micro-damage. The microneedle is embedded in the wall surface, forming a mechanical limit and greatly increasing the lateral friction of the suction cup. Attached Figure Description

[0030] The present invention will be described in detail below with reference to specific implementation examples. These examples will help those skilled in the art to further understand the present invention, but do not limit the present invention in any way.

[0031] As shown in Figures 1, 2, and 6, the device includes a DC motor 3, a vortex suction cup 8, a microneedle adsorption unit, a flow field protection unit, and a floating vortex unit. The flow field protection unit is sleeved on the outside of the vortex suction cup 8. The microneedle adsorption unit is fixedly installed on the outer wall of the flow field protection unit to increase the lateral friction during the adsorption process. The lower surfaces of the flow field protection unit and the microneedle adsorption unit are flush. The floating vortex unit is fixedly installed on the upper surface of the flow field protection unit. The outer shell of the vortex suction cup 8 is fixedly connected to the pin pressure plate 1 in the floating vortex unit. The pin pressure plate 1 is used to limit the amplitude of the vortex suction cup 8 floating up and down in the water. The output shaft of the DC motor 3 is connected to the vortex blades in the vortex suction cup 8 to drive the vortex blades of the vortex suction cup 8 to rotate, thereby forming a flow field in the water, and then achieving adsorption on the wall surface to be adsorbed through the water flow field.

[0032] Specifically, the swirling suction cup 8 mainly consists of a shell and swirling blades, with the swirling blades rotatably disposed on the inner side of the shell of the swirling suction cup 8.

[0033] The flow field protection unit includes an annular flow barrier 5, an annular sealing ring 7, and a sealing ring fixing ring 9. The vortex suction cup 8 is movably disposed inside the flow barrier 5, and the outer wall of the outer shell of the vortex suction cup 8 and the inner wall of the flow barrier 5 are in sealed contact. The sealing ring 7 and the sealing ring fixing ring 9 are both fixedly installed on the lower surface of the flow barrier 5 through a micro-needle adsorption unit. The sealing ring 7 is sealed and fitted on the outer surface of the sealing ring fixing ring 9, and the lower surfaces of the sealing ring 7 and the sealing ring fixing ring 9 are flush. When the vortex suction cup device adsorbs the wall surface to be adsorbed, the vortex blades of the vortex suction cup 8 rotate under the drive of the DC motor 3. When the sealing ring 7 contacts the wall surface to be adsorbed, the outer shell of the vortex suction cup 8, the flow barrier 5 connected to the vortex suction cup 8, the sealing ring 7, and the wall surface to be adsorbed form a closed negative pressure water chamber, so that the vortex suction cup device achieves adsorption of the wall surface to be adsorbed under the negative pressure of the closed negative pressure water chamber.

[0034] The floating swirl unit includes an annular pin pressure plate 1, a pin positioning rod 2, and a spring pin 4. A ring of pin positioning rods 2 is fixedly installed on the outer periphery of the upper surface of the flow deflector 5. The spring pin 4 is sleeved on the outer side wall of the pin positioning rod 2. The pin pressure plate 1 and the flow deflector 5 are arranged in parallel at intervals, and the pin pressure plate 1 is located above the flow deflector 5. The bottom end and the top end of the spring pin 4 are connected to the flow deflector 5 and the pin pressure plate 1, respectively, so that the pin pressure plate 1 is connected to the flow deflector 5 by moving up and down through the spring pin 4.

[0035] The pin plate 1 and the outer shell of the vortex suction cup 8 are fixedly connected. When the vortex suction cup 8 moves up and down under the impact of external water flow, the vortex suction cup 8 drives the pin plate 1 to move up and down along the axis of the spring pin 4. The spring force in the spring pin 4 buffers the movement of the vortex suction cup 8 in the up and down direction, preventing the vortex suction cup device from detaching from the wall to be adsorbed.

[0036] As shown in Figure 5, the microneedle adsorption unit mainly consists of a microneedle fixing ring 6 and several microneedles 10. A ring of microneedles 10 is fixedly installed on the outer wall of the microneedle fixing ring 6. The sealing ring 7 and the sealing ring fixing ring 9 are both installed on the lower surface of the microneedle fixing ring 6. The microneedles 10 are located outside the sealing ring 7, and the lower surface of the tip of the microneedle 10 is flush with the lower surface of the sealing ring 7. When the sealing ring 7 contacts the wall surface to be adsorbed, the microneedles 10 penetrate the wall surface to be adsorbed. The lateral friction between the microneedles 10 and the wall surface to be adsorbed achieves reliable adsorption between the vortex suction cup device and the wall surface to be adsorbed.

[0037] The top of the inner wall of the sealing ring fixing ring 9 is provided with a ring of rectangular protrusions. The rectangular protrusions are mainly formed by several downward-facing rectangular protrusions evenly spaced along the circumference of the sealing ring fixing ring 9. The bottom of the inner wall of the sealing ring fixing ring 9 is provided with a ring of rectangular flanges. The rectangular flanges are mainly formed by several inward-facing rectangular flanges evenly spaced along the circumference of the sealing ring fixing ring 9. The rectangular protrusions and rectangular flanges are located in the same circumferential direction, and the rectangular protrusions and rectangular flanges are arranged alternately along the circumference. At least one rectangular flange is provided between every two adjacent rectangular protrusions. When water flows into the vortex suction cup device, the rectangular protrusions and rectangular flanges are used to buffer the water flow to prevent excessive water flow from disrupting the flow field inside the vortex suction cup device.

[0038] The sealing ring retaining ring 9 has a U-shaped cross-section. It consists of two parallel horizontal rings and one vertical ring. The two horizontal rings are connected by the vertical ring to form a U-shaped cross-section. A rectangular protrusion is connected to the upper horizontal ring. The upper surface of the rectangular protrusion is flush with the upper surface of the sealing ring retaining ring 9, and the lower surface of the rectangular protrusion is lower than the lower surface of the sealing ring retaining ring 9. A rectangular flange is connected to the lower horizontal ring, and the upper and lower surfaces of the rectangular flange are flush with the upper and lower surfaces of the lower horizontal ring, respectively. That is, the thickness of the rectangular flange is the same as the thickness of the lower horizontal ring.

[0039] A limit bolt is installed at the top of the pin positioning rod 2. The pin pressure plate 1 is limited below the limit bolt to prevent the pin pressure plate 1 from falling off the pin positioning rod 2, thereby limiting the displacement of the vortex suction cup 8 in the vertical direction.

[0040] The outer wall of the flow deflector 5 is inclined to reduce the impact of underwater water flow on the vortex suction device. The inclination angle of the outer wall of the flow deflector 5 is in the range of 30 degrees to 45 degrees.

[0041] When the cyclone suction cup device adsorbs the wall surface to be adsorbed, the distance between the cyclone blades in the cyclone suction cup 8 and the wall surface to be adsorbed is no more than 20mm.

[0042] The flow deflector 5 is fitted over the vortex suction cup 8 to block the high-speed lateral water flow. Simultaneously, it creates a negative pressure cavity inside the vortex suction cup 8 during operation, reducing the suction cup's power consumption. The microneedle retaining ring 6 is fixedly connected to the flow deflector 5. The microneedles 10 are threaded onto the microneedle retaining ring 6. When the vortex suction cup 8 adsorbs, the compressed spring pin 4 reaches its limit position, as shown in Figure 3, applying positive pressure to the microneedles 10, causing them to pierce the wall and create micro-damage. The embedding of the microneedles 10 into the wall forms a mechanical limit, greatly increasing the lateral friction of the suction cup.

[0043] Spring pin 4 is sleeved on pin positioning rod 2. Swirl suction cup 8 is connected to spring pin 4 via pin pressure plate 1. When the suction cup moves away from the wall due to external force, the swirl suction cup 8 moves upward, and the volume of the internal cavity of the suction cup increases rapidly, causing the internal pressure to decrease. Under the action of the internal and external pressure difference, a downward force is generated, preventing the suction cup gap from increasing further. This allows the suction cup to complete self-compensation and avoids the suction failure caused by the suction cup leaving the wall due to a sudden increase in load. Pin positioning rod 2 is circumferentially fixed to flow deflector 5.

[0044] The vortex suction cup 8 is fixedly connected to the DC motor 3. The vortex suction cup 8 is fixedly connected to the external pin pressure plate 1. The vortex suction cup 8 can create a negative pressure flow field when it rotates inside the flow baffle 5. The vortex suction cup 8 can move up and down synchronously with the pin pressure plate 1, so that the vortex suction cup 8 can have a strong anti-interference ability when resisting high-speed water flow.

[0045] The sealing ring retaining ring 9 is embedded below the microneedle retaining ring 6, and the sealing ring 7 is nested outside the sealing ring retaining ring 9, which is used to increase the airtightness of the internal cavity and protect the stability of the internal flow field.

[0046] When the device adheres to the wall, the swirling suction cup rotates and discharges water to create an internal cavity. The spring pin is compressed to its end limit position, as shown in Figure 3. At this time, the gap between the swirling suction cup and the wall is at its minimum. At the same time, due to the positive pressure applied by the outside and the adsorption of the swirling suction cup, the microneedles slightly damage the wall to embed into the wall, increasing the lateral friction force of the adsorption process.

[0047] After adsorption is complete, the vortex suction cup moves up and down due to the impact of the high-velocity water flow. At this time, the flow-blocking shroud 5 can guide some of the water flow upward, reducing the direct impact of the water flow, while the microneedles 10 provide some lateral friction. As shown in Figure 4, during the upward movement of the vortex suction cup 8 due to the influence of the external high-speed water flow, the volume of the cavity below the vortex suction cup 8 increases, and the internal pressure decreases. Under the action of the internal and external pressure difference, a downward force is generated. This force has a resistance effect on external forces, preventing the suction cup gap from increasing further. The maximum protective gap is the stroke of the spring pin 4. The vortex suction cup 8 can ensure safe adsorption within 20mm of the wall surface. When it is necessary to adjust the gap during adsorption, the output torque of the servo motor 3 can be increased to increase the speed of the vortex suction cup 8, thereby making the vortex suction cup 8 return to its original position.
