Description

Technical Field

[0001] The invention relates to the technical field of navigation buildings in water transport engineering, and in particular to a ship lock chamber escape and rescue system. Background Art

[0002] Channelized river junctions typically feature navigation structures such as locks or ship lifts to accommodate ship traffic. Currently, existing locks in China primarily serve cargo vessels. Vertical ladders are typically spaced along the flow direction within the lock chambers to allow personnel to climb from the ship deck to the top of the lock.

[0003] A Chinese utility model patent (publication number: CN215595463U) discloses a lock chamber escape ladder, which includes a bollard, connectors, and a life ladder. In an emergency, this ladder eliminates the need to erect ladders on the ship's cabin roof or lock roof. While this lock chamber escape ladder can serve as an escape route for ship crew members in the event of an accident, it is less effective when a large number of people are on board. It can also easily lead to secondary accidents caused by scrambling. Personnel who fail to climb the escape ladder remain in the water or at the accident site, compromising their safety. Furthermore, the higher ladder is not conducive to escape for those with limited physical strength.

[0004] As more tourists choose to experience boat passage through the locks, demand for passenger ships is increasing. Because cargo ships have smaller crews and lower occupancy rates, vertical ladders within the lock chambers can generally meet the evacuation needs of cargo ships. However, passenger ships carry larger numbers of passengers and have a higher occupancy rate. In the event of a fire or capsizing, existing vertical ladders cannot meet the needs of rapid escape and rescue, posing a significant safety hazard. Summary of the Invention

[0005] The purpose of the present invention is to provide a ship lock chamber escape and rescue system in response to the problems existing in the prior art.

[0006] To achieve the above object, the technical solution adopted by the present invention is:

[0007] A ship lock chamber escape and rescue system comprises vertical spaces arranged in the concrete walls along both sides of the ship lock chamber, the vertical spaces being connected to the water area of the lock chamber, escape floats being respectively arranged in the vertical spaces, the escape floats being connected to the concrete walls via a number of unlockable locking devices, the escape floats being located underwater close to the bottom plate of the lock chamber in a locked state, a number of rolling support devices being provided between the outer periphery of the escape floats and the concrete walls; a number of wall steps are also provided on the side of the concrete wall facing the escape floats, the wall steps being arranged in height from the lowest navigable water level downstream to the gate top elevation.

[0008] The ship lock chamber escape and rescue system arranges the escape float and the wall steps and other structures on the water side of the concrete wall of the lock chamber, which can provide escape space and escape routes for the rescue and escape of a large number of people in the lock chamber water area, eliminates the safety hazard of falling into the water when climbing a vertical ladder, and improves the efficiency and success rate of escape and rescue.

[0009] The vertical space provided in the concrete gate wall can accommodate the escape float, and the vertical space is connected to the water area of the gate chamber, allowing water to enter the vertical space; the escape float is temporarily fixed by the unlockable locking device, which can allow the escape float to stay underwater under normal circumstances without accidents, and can ensure that the escape float will not sway and drift with the water flowing into and out of the gate chamber before it is unlocked; once an accident occurs in the water area, the unlockable locking device can be immediately opened to allow the escape float to quickly rise with the buoyancy of the water to form an escape docking platform, which is convenient for a large number of people to be transferred to the escape float. The escape float itself can accommodate a large number of people, avoiding people staying in the water or at the accident site, which is conducive to subsequent escape and rescue, and will not cause secondary accidents due to scrambling for limited vertical ladder escape, and also avoids the limited vertical ladder affecting people's escape.

[0010] The escape float can be unlocked and fixed in the underwater area. On the one hand, it does not affect the normal operation and passage of ships in the lock chamber water area. On the other hand, it avoids the wear and damage caused by the frequent rise and fall of the non-fixed float due to the long-term filling and discharge of the lock chamber water area. It can increase the life of the escape float and enable it to play an important escape and rescue role at critical moments.

[0011] The gate wall steps are arranged on the concrete gate wall, which can be docked with the floating escape float at any water surface position, so that the escaping personnel can use the gate wall steps to transfer to the ground space above the gate chamber, and it is also convenient for rescue personnel to go down from the gate wall steps to the escape float for rescue, and it is convenient to transfer the elderly, weak and disabled.

[0012] The rolling support device is arranged on the periphery of the escape float. On the one hand, it can maintain a certain gap between the escape float and the concrete gate wall, so that it can rise and move relative to the concrete gate wall. This gap is generally less than 10 cm, and preferably between 3-5 cm; on the other hand, it can be moved by using rolling support, which facilitates the smooth and rapid floating of the entire escape float.

[0013] Furthermore, from a cross-sectional view, the vertical space is provided with accommodation spaces located within the concrete gate wall at both ends in the length direction, and both ends of the escape float are respectively arranged in the accommodation spaces, and the outer contour of the escape float is adapted to the inner circumference of the vertical space.

[0014] That is, the vertical space is not a completely open C-shaped structure, but has accommodation space at both ends, so that the two ends of the escape float can be accommodated in this area, forming an overall limit. During the floating process, the escape float will not drift to other places due to the water flow, which is conducive to improving the accuracy of escape and rescue.

[0015] Furthermore, the escape float includes a float cover plate and several floats arranged under the float cover plate. Several clips are provided under the float cover plate, and mounting flange edges are provided around the top of the float, and the mounting flange edges are connected to the clips. Several fasteners are also provided on the side edges of the float cover plate, and the fasteners are used to connect the floats located at the outer edge below the float cover plate.

[0016] The buoys provide sufficient buoyancy to support the float cover and the escapees above it, forming a large escape and rescue platform with good occupancy capacity. The use of clips, mounting flanges, and fasteners facilitates the manufacture and maintenance of the escape float. The overall structure is simple and avoids the use of sharp connectors such as screws, preventing secondary injuries to people during escape.

[0017] Furthermore, the floating cover plate is a multi-layer metal cover plate, such as a steel cover plate, an aluminum alloy cover plate, etc. The metal cover plates are connected by supporting keels, and the metal cover plates are provided with anti-slip patterns and a number of drainage holes; the buoy is a PE buoy, and a water flow channel is also provided in the middle of the buoy.

[0018] The floating cover, formed by connecting multiple layers of steel cover plates and supporting keels, has good strength and stability, making it suitable for use as an escape platform. The steel cover plate can also be made of high-strength aluminum alloy cover plates, which will be lighter. The provision of anti-slip patterns on the metal cover plate can prevent escapees from slipping and falling in slippery water bodies, thereby improving the success rate and effectiveness of escape and rescue. The provision of the drainage holes, on the one hand, allows water to flow through during the ascent of the escape float, reducing water pressure and facilitating the rapid ascent of the escape float, and on the other hand, can reduce the accumulation of water on the floating cover plate after buoyancy. The use of PE floats has good durability, and the provision of the water flow channel facilitates drainage and reduces the accumulation of water on the float.

[0019] Furthermore, one side of the escape float extends toward the lock chamber water area. This allows the escape float to be closer to the middle area of the lock chamber water area, facilitating the rapid transfer of personnel on board to the escape float. The shortened distance increases the possibility of escaping by swimming or using the platform.

[0020] Furthermore, the unlockable locking device is a normally closed electromagnetic lock. The lock body of the normally closed electromagnetic lock is embedded in the concrete lock wall, and the cable is led out of the concrete lock wall through a waterproof casing. The suction plate of the normally closed electromagnetic lock is fixedly mounted on the outer wall of the escape float. The normally closed electromagnetic lock facilitates the synchronous unlocking of the lock by the lock operator from the control room.

[0021] Alternatively, the unlockable locking device comprises a remotely controlled smart lock installed beneath the escape float. A chain is connected to the lock opening of the smart lock, the other end of which is connected to a pull ring anchored in the lock chamber floor. This smart lock also facilitates unlocking by lock chamber personnel via a remote terminal, or other mechanical release methods, ensuring the escape float can be promptly floated.

[0022] During the actual layout process, a video monitoring system and an alarm system are installed above the lock chamber. Once a ship accident is monitored, the information can be transmitted to the control room in a timely manner, and the personnel on the ship can also call the police for help through wireless communication.

[0023] Furthermore, the rolling support device includes a bracket and a roller, the bracket is installed on the escape float near the unlockable locking device, the roller is installed on the bracket, and the roller abuts the wall of the concrete gate wall; or a plurality of vertical slide grooves are provided on the wall of the concrete gate wall, and the roller is arranged in the vertical slide grooves.

[0024] Furthermore, two opposite gate wall steps are arranged on each side of the concrete gate wall, enabling escape from multiple directions; the gate wall steps are provided with a rest platform at intervals of 2 to 3 meters from bottom to top, so that the escaping personnel can rest and replenish their energy during the journey.

[0025] Furthermore, it also includes a method for escape and rescue using the escape float: when a ship is wrecked in the lock chamber waters, the lock operation and management personnel open the switch of the unlockable locking device through the remote control terminal, and the escape float automatically floats to the water surface of the lock chamber waters by its own buoyancy. The wrecked people escape from the wrecked ship or the lock chamber waters to the escape float as soon as possible, and then escape from the lock wall to the road surface on the top of the lock through the escape float. People who are physically weak or the elderly and children stay on the escape float or move to the rest platform to wait for rescue.

[0026] Compared with the prior art, the beneficial effects of the present invention are: 1. The lock chamber escape and rescue system of the ship lock chamber arranges the escape float and the wall steps and other structures on the water side of the lock chamber concrete wall, which can provide escape space and escape routes for the rescue and escape of a large number of people in the lock chamber water area, eliminates the safety hazard of falling into the water when climbing a vertical ladder, and improves the efficiency and success rate of escape and rescue; 2. The escape float is temporarily fixed by the unlockable locking device, which can keep the escape float underwater under normal circumstances without accidents, and can ensure that the escape float will not sway and drift with the water in the lock chamber before it is unlocked; once an accident occurs in the water area, the unlockable locking device can be immediately opened to allow the escape float to quickly rise with the buoyancy of the water to form an escape docking platform, which is convenient for a large number of people to transfer to the escape float, which is beneficial to subsequent escape and rescue, and will not be caused by competition The limited vertical ladder escape may cause secondary accidents, and the limited vertical ladder may affect the escape of personnel; 3. The escape float can be unlocked and fixed in the underwater area. On the one hand, it does not affect the normal operation and passage of ships in the lock chamber water area. On the other hand, it also avoids the wear and damage caused by the frequent rise and fall of the non-fixed float as the lock chamber water area is filled and discharged for a long time; 4. The gate wall step can be docked with the floating escape float at any water surface position, allowing the escaping personnel to use the gate wall step to transfer to the ground space above the lock chamber, and it is also convenient for rescue personnel to go down from the gate wall step to the escape float for rescue; 5. The rolling support device is arranged on the periphery of the escape float. On the one hand, it can maintain a certain moving gap between the escape float and the concrete gate wall, and on the other hand, it can be moved by using the rolling support, which facilitates the smooth and rapid floating of the entire escape float.

[0039] The following will clearly and completely describe the technical solution of the present invention in conjunction with the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0040] In the description of the present invention, it should be noted that the terms "middle", "upper", "lower", "left", "right", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings. They are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific direction, be constructed and operated in a specific direction. Therefore, they cannot be understood as limiting the present invention.

[0041] Example 1:

[0042] like Figures 1 to 7As shown, a ship lock chamber escape and rescue system includes vertical spaces 2 set in the concrete walls 1 along both sides of the ship lock chamber, the vertical spaces 2 are connected to the lock chamber water area 3, and escape floats 6 are respectively provided in the vertical spaces 2. The escape floats 6 are connected to the concrete walls 1 through a number of unlockable locking devices 7. The escape floats 6 are located underwater near the lock chamber bottom plate 8 in the locked state, and a number of rolling support devices 9 are also provided between the outer periphery of the escape floats 6 and the concrete walls 1; a number of wall steps 4 are also provided on the side of the concrete wall 1 facing the escape floats 6, and the wall steps 4 are arranged in the height direction from the lowest navigable water level downstream to the gate top elevation.

[0043] The ship lock chamber escape and rescue system arranges the escape float 6 and the wall steps 4 and other structures on the water side of the concrete wall 1 of the lock chamber, which can provide escape space and escape routes for the rescue and escape of a large number of people in the lock chamber water area, eliminates the safety hazard of falling into the water when climbing a vertical ladder, and improves the efficiency and success rate of escape and rescue.

[0044] The vertical space 2 is set in the concrete gate wall 1 to accommodate the escape float 6. The vertical space 2 is connected to the lock chamber water area 3, allowing water to enter the vertical space 2; the escape float 6 is temporarily fixed by the unlockable locking device 7, which can allow the escape float 6 to stay underwater under normal circumstances without accidents, and can ensure that the escape float 6 will not sway and drift with the water flowing into the lock chamber before it is unlocked; once a water accident occurs, the unlockable locking device 7 can be immediately opened to allow the escape float 6 to quickly rise with the buoyancy of the water to form an escape docking platform, which is convenient for a large number of people to be transferred to the escape float 6. The escape float 6 itself can accommodate a large number of people, avoiding people staying in the water or at the accident site, which is conducive to subsequent escape and rescue, and will not cause secondary accidents due to competing for limited vertical ladders to escape, and also avoids the limited vertical ladders affecting people's escape.

[0045] The escape float 6 can be unlocked and fixed in the underwater area. On the one hand, it does not affect the normal operation and passage of ships in the lock chamber water area. On the other hand, it avoids the wear and damage caused by the frequent rise and fall of the non-fixed float due to the long-term inflow and outflow of the lock chamber water area. It can increase the life of the escape float and enable it to play an important role in escape and rescue at critical moments.

[0046] The gate wall step 4 is provided on the concrete gate wall 1, which can dock with the floating escape float 6 at any water surface position, so that the escaping personnel can use the gate wall step 4 to transfer to the ground space above the gate chamber, and it is also convenient for rescue personnel to go down from the gate wall step 4 to the escape float for rescue, thereby facilitating the transfer and rescue of the elderly, weak and disabled.

[0047] The rolling support device 9 is arranged on the outer periphery of the escape float 6. On the one hand, it can maintain a certain gap between the escape float 6 and the concrete gate wall 1, so that it can rise and move relative to the concrete gate wall 1. This gap is generally less than 10 cm, preferably between 3-5 cm; on the other hand, it can be moved by using rolling support, which facilitates the smooth and rapid floating of the entire escape float 6.

[0048] The escape float 6 can also be used repeatedly. After an accident rescue is completed and the accident ship is handled, the water level is lowered to the lowest level by draining water, and the escape float is then lowered. The escape float 6 is then reconnected and fixed using the unlockable locking device 7 for the next use. During daily or regular maintenance of the lock chamber, the escape float also needs to be maintained to ensure that its various modules are functioning properly.

[0049] Furthermore, from a cross-sectional view, the vertical space 2 is provided with a receiving space 201 located within the concrete gate wall 1 at both ends in the length direction, and the two ends of the escape float 6 are respectively arranged in the receiving space 201, and the outer contour of the escape float 6 is adapted to the inner periphery of the vertical space 2.

[0050] That is, the vertical space 2 is not a completely open C-shaped structure, but is provided with an accommodation space 201 at both ends, so that the two ends of the escape float 6 can be accommodated in this area to form an overall limit. During the floating process, the escape float 6 will not drift to other places due to the water flow, which is conducive to improving the accuracy of escape and rescue.

[0051] Furthermore, the escape float 6 includes a float cover 601, and a plurality of floats 602 arranged in an array below the float cover 601, a plurality of clips 604 are provided below the float cover 601, and mounting flanges 605 are provided around the top of the float 602, and the mounting flanges 605 are connected to the clips 604; a plurality of fasteners 606 are also provided on the side edges of the float cover 601, and the fasteners 606 are used to connect the float 602 located at the outer edge below the float cover 601.

[0052] The buoys 602 provide sufficient buoyancy to support the float cover 601 and the escapees above it. The float cover 601 forms a large escape and rescue platform with good occupancy capacity. The attachment and installation method using the clips 604, mounting flange 605, and fasteners 606 facilitates the manufacture and maintenance of the escape float. The overall structure is simple and avoids the use of sharp connectors such as screws, preventing secondary injuries to people during escape.

[0053] Furthermore, the floating cover plate 601 is a multi-layer metal cover plate, such as a steel cover plate, an aluminum alloy cover plate, etc. The metal cover plates are connected by a supporting keel 603, and the metal cover plate is provided with anti-slip grooves and a plurality of drainage holes; the buoy 602 is a PE buoy, and a water flow channel 607 is also provided in the middle of the buoy 602.

[0054] The floating cover plate 601, formed by connecting multiple layers of steel cover plates and supporting keels, has good strength and stability and is suitable for use as an escape platform. The steel cover plate can also be made of high-strength aluminum alloy cover plates, which will be lighter. The provision of anti-slip patterns on the metal cover plate can prevent escapees from slipping and falling in slippery water bodies, thereby improving the success rate and effectiveness of escape and rescue. The provision of the drainage holes, on the one hand, allows water to flow through during the ascent of the escape float, reducing water pressure and facilitating the rapid ascent of the escape float. On the other hand, it can reduce the accumulation of water on the floating cover plate 601 after buoyancy. The use of PE floats has good durability, and the provision of the water flow channel 607 facilitates drainage and reduces the accumulation of water on the float.

[0055] Furthermore, the unlockable locking device 7 is a normally closed electromagnetic lock 10. The lock body of the normally closed electromagnetic lock 10 is embedded in the concrete gate wall 1, and the cable is led out of the concrete gate wall 1 through a waterproof casing. The adsorption plate 11 of the normally closed electromagnetic lock 10 is fixedly mounted on the outer wall of the escape float 6. The normally closed electromagnetic lock 10 facilitates the synchronous unlocking control of the lock by the lock operator in the control room.

[0056] The normally closed electromagnetic lock can be a mature product available on the market. It is convenient to control the adsorption and separation operations with the adsorption plate 11 through electromagnetic control. An electromagnetic lock with a larger adsorption force can be selected. Multiple normally closed electromagnetic locks are distributed at intervals on the periphery of the escape float to provide suction from the direction of the entire periphery to temporarily fix the escape float.

[0057] During the actual layout process, a video monitoring system and an alarm system are also installed above the lock chamber. Once a ship accident is monitored, the information can be transmitted to the control room in a timely manner, and the personnel on the ship can also call the police for help through wireless communication.

[0058] Furthermore, the rolling support device 9 includes a bracket 901 and rollers 902. The bracket 901 is mounted on the escape float 6 near the unlockable locking device 7. The rollers 902 are mounted on the bracket 901, and the rollers 902 abut against the wall of the concrete gate wall 1. After unlocking, under the buoyancy of the water, the rollers 902 arranged around the periphery can effectively move the escape float 6 upward along the vertical space 2 until it reaches the water surface.

[0059] Furthermore, two oppositely oriented gate wall steps 4 are arranged on each side of the concrete gate wall 1, enabling escape from multiple directions. Resting platforms 5 are arranged every 2 to 3 meters from bottom to top of the gate wall steps 4, allowing escapees to rest and replenish their energy. The gate wall steps 4 are cast using formwork during the construction of the concrete gate wall 1.

[0060] Furthermore, the method of using the escape float for escape and rescue is as follows: when a ship is wrecked in the lock chamber waters, the ship lock operator opens the switch of the unlockable locking device 7 through a remote control terminal or in the control room, unlocking all the locks with one click. The escape float 6 automatically floats to the surface of the lock chamber waters 3 by its own buoyancy. The wrecked personnel immediately escape from the wrecked ship or the lock chamber waters to the escape float 6, and then escape from the lock wall steps 4 to the road surface at the top of the lock via the escape float 6. Those who are physically weak or the elderly and children can stay on the escape float 6 or move to the rest platform 5 to wait for rescue. This escape method can greatly improve the efficiency and accuracy of escape and rescue, ensuring the safety of personnel.

[0061] Example 2:

[0062] The difference between this embodiment and the first embodiment is that a lockable and unlockable device with another structure is provided.

[0063] like Figure 8 As shown, the unlockable locking device 7 includes a remotely controlled smart lock 12, which is installed below the floating cover 601. A chain 13 is connected to the lock opening of the smart lock 12, and the other end of the chain 13 is connected to a pull ring 14 anchored in the lock chamber bottom plate 8. The provision of the smart lock 12 also facilitates unlocking by the lock chamber manager through a remote terminal.

[0064] The smart lock comprises a metal body housing a mainboard and various position sensors. The mainboard integrates GPS, GPRS, power supply, and storage modules, enabling unlocking operations via the IoT system. When the smart lock receives an unlock command, a motor drives an eccentric disc to rotate. A lever on the disc disengages the latch, allowing the lock to automatically retract under spring tension, releasing the chain 13. Once unlocked, the chain drops, causing the escape float to rise.

[0065] This connection method can reduce the number of unlockable locking devices 7 used. Usually, one set is set at each of the four corners to fix the entire escape float; the pull ring 14 is preset in the lock chamber bottom plate 8 by anchoring, which can provide sufficient pulling force.

[0066] Example 3:

[0067] The difference between this embodiment and the first embodiment is that a rolling support device of another structure is provided.

[0068] like Figure 9 and Figure 10 As shown, a plurality of vertical chute 15 are provided on the wall of the concrete gate wall 1, and the roller 902 is arranged in the vertical chute 15. The cross section of the vertical chute 15 can be T-shaped. Through the setting of such a chute, the roller 902 has a limiting effect and a good guiding effect.

[0069] Example 4:

[0070] This embodiment provides another structure of an escape float.

[0071] like Figure 11 As shown, one side of the escape float 6 also extends toward the lock chamber water area 3. In this case, the escape float 6 can be brought closer to the middle area of the lock chamber water area 3, which is conducive to the rapid transfer of personnel on the ship to the escape float. The shortened distance makes it more likely that people can swim over or use the step to escape.

[0072] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
