[0011] The method for installing a non-destructive adsorption connection device for underwater construction comprises the following steps: S1. Transport the underwater construction non-destructive adsorption connection device to the top of the hydraulic structure that requires underwater drilling and reinforcement planting; S2. After connecting the pipes and lines, use the lifting rope to sink the negative pressure adsorption locator down into the water along the side wall of the hydraulic structure. After the diver places the negative pressure adsorption locator at a suitable position on the side wall of the hydraulic structure, a signal is sent upwards; S3, start the submersible pump first, the submersible pump draws clean water through the high-pressure water pipe into the annular injection pipe, and finally sprays it out from several small injection holes on the right side of the injection pipe. At this time, the diver swings the negative pressure adsorption positioner, and the jet water sprayed from the injection pipe removes the algae and other attachments attached to the side wall of the hydraulic structure, and then shuts down the submersible pump; S4. The diver makes the inner rubber sleeve and the outer rubber sleeve on the right side of the negative pressure adsorption positioner contact the side wall of the hydraulic structure, starts the servo motor, and evacuates the cavity formed between the cover plate and the inner rubber sleeve until the negative pressure adsorption positioner is adsorbed on the side wall of the hydraulic structure, and connects the upper end of the suspension rope to the fixed connection point on the top of the hydraulic structure; S5. The diver hangs the punching and reinforcing bar tool kit he carries with him to the connection hole on the handle; S6. Divers perform drilling and rebar planting operations in the vicinity of the negative pressure adsorption locator; S7. After the drilling and rebar planting operation in this area is completed, the servo motor is turned off, and the diver loosens the air pressure balance bolt on the cover plate. Water enters the inner rubber sleeve, and the negative pressure in the cavity between the cover plate and the inner rubber sleeve disappears. The entire negative pressure adsorption positioner is moved to the next area, and steps S3-S6 are repeated.

[0012] The specific process of step S4 is as follows: the right ends of the inner rubber sleeve and the outer rubber sleeve are in contact with the underwater side wall of the hydraulic structure, the control valve is closed first, the first drain valve is opened, the servo motor is started, the air-water suction pump works, the suction pipe draws out the water inside the cover plate and discharges it through the first drain pipe, when the amount of water discharged from the first drain pipe becomes smaller, the control valve is opened, the first drain valve is closed, the air-water suction pump draws the air-water mixture into the steel tank, the cavity inside the inner rubber sleeve and the cover plate and the annular cavity between the inner rubber sleeve and the outer rubber sleeve are all sucked into a negative pressure state, and the right ends of the inner rubber sleeve and the outer rubber sleeve are The surface is tightly adsorbed on the underwater side wall of the hydraulic structure; the steel tank separates the sucked gas and water, the gas is discharged from the exhaust pipe on the top, and the water is temporarily stored at the bottom of the steel tank. The second drain valve is opened at regular intervals to discharge the water and mud in the steel tank; the pressure sensor monitors the vacuum degree inside the steel tank in real time and transmits the pressure signal to the PLC controller. The PLC controller sets the vacuum degree range. When the vacuum degree is lower than the minimum value of the set range, the PLC controller commands the servo motor to start and the gas-water suction pump to work. When the vacuum degree reaches the maximum value of the set range, the PLC controller commands the servo motor to shut down and the gas-water suction pump stops; If the surface of the underwater side wall of the hydraulic structure is not smooth and flat, in order to improve the negative pressure adsorption effect, when the inner rubber sleeve and the outer rubber sleeve are just adsorbed to the underwater side wall of the hydraulic structure, the first waterproof wire and the second waterproof wire are energized, and the inner electric heating wire and the outer electric heating wire heat the inner rubber sleeve and the outer rubber sleeve respectively. The inner rubber sleeve and the outer rubber sleeve expand and soften due to the heat, and the right end annular surfaces of the inner rubber sleeve and the outer rubber sleeve are deformed under the action of external water pressure and atmospheric pressure. The right end annular surfaces of the deformed inner rubber sleeve and the outer rubber sleeve are in full contact with the surface of the underwater side wall of the hydraulic structure, thereby improving the sealing effect. Subsequently, the first waterproof wire and the second waterproof wire are de-energized, and the right end annular surfaces of the inner rubber sleeve and the outer rubber sleeve maintain full annular sealing contact with the surface of the underwater side wall of the hydraulic structure after external water cooling.

[0013] In step S2, when the side wall of the hydraulic structure is a slope or a channel slope, the air injection pump is started, and the air injection pipe is raised to inject high-pressure air into the cylinder of the guide support wheel assembly. The high-pressure air drives the piston to move in the steel cylinder, and the piston drives the telescopic rod to extend outward. The universal wheel is supported on the slope or the channel slope, and the air injection pressure of the air injection pump is kept stable. The negative pressure adsorption positioner does not contact the slope or the channel slope, and slides down the slope or the channel slope to below the water surface through the universal wheel; before starting the servo motor in step S4, the air injection pump is turned off, and under the elastic force of the spring, the piston and the telescopic rod are driven to move in the opposite direction, and the universal wheel is separated from the slope or the channel slope.

[0014] By adopting the above technical solution, the present invention has outstanding substantive features and significant progress compared with the prior art, as follows: 1) The steel tank is used to store the water and gas extracted from the negative pressure adsorption positioner, and is the main carrier for forming vacuum and water-gas separation; the air-water suction pump is the main mechanical power facility driven by the servo motor to generate vacuum, and the negative pressure adsorption positioner is a special facility used to form vacuum adsorption on the surface of hydraulic structures, forming an underwater adsorption anchor point; the vacuum control unit is used to monitor the vacuum degree inside the negative pressure adsorption positioner, and start and shut down the air-water suction pump in real time to maintain the vacuum adsorption force inside the negative pressure adsorption positioner.

[0015] 2) The cover plate, inner locating ring and outer locating ring are made in one piece. The annular groove formed between the inner locating ring and the outer locating ring is used to install the inner rubber sleeve and the outer rubber sleeve. The inner rubber sleeve and the outer rubber sleeve are crimped and positioned by a pressing ring. Since the width of the annular groove gradually increases from the groove mouth to the groove bottom, the thickness of the inner rubber sleeve and the outer rubber sleeve in the annular groove gradually decreases from left to right, and the thickness of the pressing ring gradually increases from left to right. In this way, when the pressing ring is connected to the cover plate by the countersunk bolt, the pressing ring presses the inner rubber sleeve and the outer rubber sleeve to form a wedge-shaped pressing structure, so that the inner rubber sleeve and the outer rubber sleeve are tightly fixed in the annular groove.

[0016] 3) An annular cavity is formed between the inner rubber sleeve and the outer rubber sleeve, and the inner rubber sleeve and the outer rubber sleeve are in contact with the underwater concrete slab at the same time. Under the condition of internal negative pressure, the two rubber sleeves not only improve the negative pressure adsorption connection strength between the entire negative pressure adsorption positioner and the hydraulic structure, but also improve the sealing between the surface of the hydraulic structure.

[0017] 4) The right half of the inner rubber sleeve expands outward to the same diameter as the outer diameter of the outer locating ring, and the right half of the inner rubber sleeve expands inward to the same diameter as the inner diameter of the inner locating ring; this structure can increase the thickness and strength of the inner rubber sleeve and the inner rubber sleeve, and the inner rubber sleeve and the inner rubber sleeve can be supported by the inner locating ring and the outer locating ring respectively in the axial direction.

[0018] 5) For the jet pipe, before vacuum adsorption, the submersible pump can be started to suck clean water and spray it out through the small jet holes on the jet pipe. The high-pressure jet water can remove algae or other debris attached to the side wall surface of the hydraulic structure. In addition, since the surface of the hydraulic structure is not smooth and flat, in order to improve the sealing performance between the right end ring surface of the inner rubber sleeve and the outer rubber sleeve and the uneven surface of the hydraulic structure, the inner and outer electric heating wires are respectively embedded in the right side of the inner and outer rubber sleeves. After the inner and outer electric heating wires are powered on, the right ends of the inner and outer rubber sleeves are heated and softened, so that the right end ring surfaces of the inner and outer rubber sleeves are tightly fitted with the surface of the hydraulic structure. After power is off, the inner and outer rubber sleeves are deformed by the water-cooled annular end faces to keep them tightly fitted with the surface of the hydraulic structure, thereby improving the negative pressure adsorption effect. Due to the good sealing performance, in order to improve the underwater construction efficiency and facilitate the rapid transfer of the negative pressure adsorption positioner, the internal vacuum is eliminated by unscrewing the air pressure balance bolt.

[0019] 6) The handle has three functions. The first is to enhance the connection strength between the pipe joint and the cover plate; the second is to provide anchor connection holes to facilitate the connection of equipment for underwater construction or repair operations; the third is to facilitate the removal of the negative pressure adsorption locator during transportation.

[0020] 7) The function of the check valve is to prevent the water sucked into the steel tank or pipeline from flowing back into the negative pressure adsorption positioner when the air-water suction pump stops, thereby reducing or even losing the anchoring effect.

[0021] 8) The pressure sensor monitors the vacuum degree inside the steel tank in real time and transmits the pressure signal to the PLC controller. The PLC controller sets the vacuum degree range. When the vacuum degree is lower than the minimum value of the set range, the PLC controller commands the servo motor to start and make the gas-water suction pump work. When the vacuum degree reaches the maximum value of the set range, the PLC controller commands the servo motor to shut down and make the gas-water suction pump rest.

[0022] In summary, the present invention has a scientific principle, utilizes vacuum suction, water-gas separation, vacuum degree control and other technologies, integrates vacuum adsorption as an underwater non-destructive anchor connection point, provides a tool kit attachment point for underwater drilling and rebar planting, reduces the burden of divers during work, and improves work efficiency. The present invention can also be used for other anchor points for underwater operations or anchor points for water operations. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The method for installing a non-destructive adsorption connection device for underwater construction comprises the following steps: S1. Transport the underwater construction non-destructive adsorption connection device to the top of the hydraulic structure 8 that needs underwater drilling and reinforcement planting; S2. After connecting the pipes and lines, use the lifting rope to sink the negative pressure adsorption locator 4 down along the side wall of the hydraulic structure 8 into the water. After the diver places the negative pressure adsorption locator 4 at a suitable position on the side wall of the hydraulic structure 8, a signal is sent upward; S3, first start the submersible pump 37, the submersible pump 37 draws clean water through the high-pressure water pipe into the annular injection pipe 36, and finally sprays it out from a number of small injection holes on the right side of the injection pipe 36. At this time, the diver swings the negative pressure adsorption positioner 4, and the jet water sprayed by the injection pipe 36 removes the algae and other attachments attached to the side wall of the hydraulic structure 8, and then the submersible pump 37 is turned off; S4, the diver makes the inner rubber sleeve 22 and the outer rubber sleeve 24 on the right side of the negative pressure adsorption positioner 4 contact the side wall of the hydraulic structure 8, starts the servo motor 40, and evacuates the cavity formed between the cover plate 17 and the inner rubber sleeve 22 until the negative pressure adsorption positioner 4 is adsorbed on the side wall of the hydraulic structure 8, and connects the upper end of the suspension rope to the fixed connection point on the top of the hydraulic structure 8; S5, the diver hangs the punching and reinforcing bar implanting tool kit he carries with him to the connecting hole 39 on the handle 38; S6, the diver performs drilling and reinforcing bar planting operations in the vicinity of the negative pressure adsorption positioner 4; S7. After the drilling and rebar planting operation in this area is completed, the servo motor 40 is turned off, and the diver loosens the air pressure balance bolt 42 on the cover plate 17. Water enters the inner rubber sleeve 22, and the negative pressure in the cavity between the cover plate 17 and the inner rubber sleeve 22 disappears. The entire negative pressure adsorption positioner 4 is moved to the next area, and steps S3-S6 are repeated.

[0033] The specific process of step S4 is as follows: the right ends of the inner rubber sleeve 22 and the outer rubber sleeve 24 are in contact with the underwater side wall of the hydraulic structure 8, the control valve 16 is closed first, the first drain valve 11 is opened, the servo motor 40 is started, the air-water suction pump 3 works, the suction pipe 5 draws out the water inside the cover plate 17 and discharges it through the first drain pipe 6, when the amount of water discharged from the first drain pipe 6 becomes smaller, the control valve 16 is opened, the first drain valve 11 is closed, the air-water suction pump 3 draws the air-water mixture into the steel tank 10, the cavity inside the inner rubber sleeve 22 and the cover plate 17 and the annular cavity between the inner rubber sleeve 22 and the outer rubber sleeve 24 are all sucked into a negative pressure state, and the inner rubber sleeve 22 and the outer rubber sleeve 24 are sucked into a negative pressure state. The right end face of the rubber sleeve 24 is tightly adsorbed on the underwater side wall of the hydraulic structure 8; the steel tank 10 separates the sucked gas and water, the gas is discharged from the exhaust pipe 14 at the top, and the water is temporarily stored at the bottom of the steel tank 10. The second drain valve 13 is opened at regular intervals to discharge the water and mud in the steel tank 10; the pressure sensor 45 monitors the vacuum degree inside the steel tank 10 in real time, and transmits the pressure signal to the PLC controller 44. The PLC controller 44 sets the vacuum degree range according to the setting. When the vacuum degree is lower than the minimum value of the setting range, the PLC controller 44 commands the servo motor 40 to start, so that the gas-water suction pump 3 works. When the vacuum degree reaches the maximum value of the setting range, the PLC controller 44 commands the servo motor 40 to shut down, and the gas-water suction pump 3 stops; If the surface of the underwater side wall of the hydraulic structure 8 is not smooth and flat, in order to improve the negative pressure adsorption effect, when the inner rubber sleeve 22 and the outer rubber sleeve 24 are just adsorbed to the underwater side wall of the hydraulic structure 8, the first waterproof wire and the second waterproof wire are energized, and the inner electric heating wire 26 and the outer electric heating wire 27 heat the inner rubber sleeve 22 and the outer rubber sleeve 24 respectively. The inner rubber sleeve 22 and the outer rubber sleeve 24 expand and soften due to the heat, and the right end annular surfaces of the inner rubber sleeve 22 and the outer rubber sleeve 24 are deformed under the action of external water pressure and atmospheric pressure.
