Air energy storage type water-saving ship lock and control method thereof

Abstract

The present invention provides an air-energy-storage water-saving ship lock and a water supply control method thereof. The air-energy-storage water-saving ship lock comprises a ship lock main structure and a water-saving tank structure disposed on the side of the ship lock main structure. The water-saving tank structure comprises a tank body, a compression cover, an air-energy-supply assembly, a transmission assembly, and a water-transfer assembly. When the compression cover is in a downward position, the air-energy-supply assembly drives the transmission assembly to move the compression cover downward along the inner wall of the tank body, thereby driving water in the tank body into the lock chamber through the water-transfer assembly and a first transverse water-transfer corridor for water replenishment. When the compression cover is in an upward position, the air-energy-supply assembly drives the transmission assembly to move the compression cover upward along the inner wall of the tank body, thereby allowing water in the lock chamber to enter the tank body through the first transverse water-transfer corridor and the water-transfer assembly. Compared to existing water-saving ship locks, this system can significantly reduce water consumption, eliminate the need to divert water from a new external reservoir, significantly reduce the need for new water source reservoirs and water diversion system projects, and significantly save project costs.

Description

Technical Field

[0001] The present invention relates to the technical field of ship locks, and in particular to an air energy storage type water-saving ship lock and a water supply control method thereof. Background Art

[0002] Water is particularly precious in areas where water is scarce, or in canal areas where pumping costs are high (such as the Xianggui Canal and the Pinglu Canal). A water-saving ship lock features a water-saving reservoir on one or both sides of the lock chamber. The reservoir receives some of the water during discharge and refills it back into the lock chamber when needed, reducing the need to pump water from external sources. By recycling the water in the water-saving reservoir, the total amount of water required for ship passage can be significantly reduced.

[0003] The working process of the existing water-saving ship lock is: when the water level in the lock chamber needs to be lowered to allow ships to go down, the water is first discharged into the water-saving pool. Due to the effect of atmospheric pressure, when the water level in the lock chamber is flush with the water level in the water-saving pool, the water in the lock chamber is not yet flush with the downstream water level. The remaining water in the lock chamber needs to be discharged downstream through the water transfer corridor connected to the downstream until it is flush with the downstream water level, and the ship can go down.

[0004] When a ship needs to sail from downstream to upstream (upstream), it needs to first collect the water in the water-saving tank into the lock chamber. Due to the effect of atmospheric pressure, the water in the water-saving tank cannot fill the lock chamber and is not yet flush with the upstream water level. Therefore, after the water levels of the water-saving tank and the lock chamber are flush, the insufficient water in the lock chamber is supplemented by diverting water from the water transfer corridor connected to the upstream or from a new reservoir outside the water-saving tank, until the water level in the lock chamber is flush with the upstream, and the ship can continue to go upstream.

[0005] Therefore, the actual water savings achieved by existing water-saving ship locks remain limited. For example, once the water level in the lock chamber reaches the water level in the water-saving reservoir during the downstream process, the water must be drained downstream until it reaches the downstream water level. During the upstream process, water must be supplied from upstream or diverted from a new reservoir outside the water-saving reservoir. Existing water-saving ship locks have not completely solved the water shortage problem, and building new reservoirs involves extensive, large-scale, and costly construction. Furthermore, the water diversion system involves even more complex issues, including reservoir site selection, foundation waterproofing, and channel and tunnel geological conditions.

[0006] In view of this, it is necessary to propose an air energy storage water-saving ship lock and a water supply control method thereof to solve or at least alleviate the above-mentioned defects. Summary of the Invention

The second transverse water delivery corridor is connected to the first transverse water delivery corridor. When the water delivery valve hoist drives the water delivery gate to move vertically to the lower limit position, the first transverse water delivery corridor is in a blocked state to prevent water from flowing between the pool body and the gate chamber.

[0043] Please see the attached Figures 1 to 5An air energy storage water-saving ship lock according to an embodiment of the present invention includes a ship lock main structure 10 and a water-saving tank structure 20 provided on the side of the ship lock main structure 10, wherein the ship lock main structure 10 includes a first transverse water transfer corridor 121 communicating with a lock chamber 110;

[0044] The water-saving tank structure 20 includes a tank body 210, a compression cover 220, an air energy supply assembly (not shown), a transmission assembly 240, and a water supply assembly (not shown). The tank body 210 is provided with a communication hole (not shown) through which the water supply assembly passes. One end of the water supply assembly is connected to the tank body 210 through the communication hole, and the other end of the water supply assembly is connected to the first transverse water supply corridor. The compression cover 220 is movable along the inner wall of the tank body 210 and is in movable sealing contact with the inner wall of the tank body 210. The top of the compression cover 220 is connected to the transmission assembly 240, and the transmission assembly 240 is connected to the air energy supply assembly. The compression cover 220 has a downward state and an upward state along the height direction of the tank body 210.

[0045] Among them, when the compression cover 220 is in the downward state, the air energy supply component drives the transmission component 240 to drive the compression cover 220 to move downward along the inner wall of the pool body 210, thereby driving the water in the pool body 210 to enter the gate chamber 110 through the water delivery component and the first horizontal water delivery corridor 121 to replenish water; when the compression cover 220 is in the upward state, the air energy supply component drives the transmission component 240 to drive the compression cover 220 to move upward along the inner wall of the pool body 210, so that the water in the gate chamber 110 enters the pool body 210 through the first horizontal water delivery corridor 121 and the water delivery component.

[0046] Specifically, when a ship needs to sail from downstream to upstream (upstream), the air energy supply component (such as an air compressor or a starting pump) starts working to generate a high-pressure air source, which is transmitted to the compression cover 220 through the transmission component 240. The compression cover 220 moves downward along the inner wall of the pool body 210 under the drive of the power and is in the downward state. Due to the downward movement of the compression cover 220, the water in the pool body 210 is compressed and transported to the first horizontal water transfer corridor 121 through the water transfer component to enter the lock chamber 110, completing the water replenishment process. During this process, the water level in the lock chamber 110 rises until it is flush with the upstream water level, and the ship can continue to go upstream.

[0047] Conversely, when the water level in the lock chamber 110 needs to be lowered to facilitate the vessel's descent, the air energy supply assembly can operate in reverse, or, in accordance with the counterweight assembly 260 described later, the transmission assembly 240 drives the compression cover 220 upward along the inner wall of the tank body 210, entering an upward state. At this point, due to the pressure differential, the water in the lock chamber 110 flows back to the water supply assembly through the first transverse water supply corridor 121 and ultimately enters the tank body 210 for storage until it returns to a set liquid level (e.g., the initial liquid level). At this point, the water level in the lock chamber 110 drops to the same level as the downstream water level, allowing the vessel to descend and preparing for the next water replenishment process.

[0048] As a good example, Figure 5 As shown, there are multiple water-saving tank structures 20, and the multiple water-saving tank structures 20 are arranged at intervals along the extension direction of the ship lock main structure 10. Preferably, multiple water-saving tank structures 20 can be set on both sides of the ship lock main structure 10.

[0049] The present application scheme controls the flow of water between the water-saving tank and the lock chamber 110, and the medium used is still water. Compared with the existing water-saving ship lock, the water consumption can be greatly reduced, and even only a small amount of water is needed to make up for the water caused by leakage. The theoretical water saving amount can reach more than 95%; as long as the water volume of the water-saving tank can meet the water volume demand of the lock chamber 110, the traditional water transfer corridors of the existing ship lock (such as the water transfer corridor for connecting the upstream and the lock chamber, and the water transfer corridor for connecting the downstream and the lock chamber) can be omitted, and the water transfer type of the traditional ship lock can be changed; the present application does not need to divert water from a new external reservoir, which greatly reduces the construction of new water source reservoirs and water diversion system projects, and greatly saves project costs; using air as a power source is not only environmentally friendly and pollution-free, but also relatively low in cost, in line with the concept of green and sustainable development, natural air can be used in the storage tank, which is non-toxic and pollution-free, and production and operation are safe and guaranteed.

[0050] As a preferred embodiment, Figure 1 As shown, the air energy supply component includes an air compressor 231, an air storage tank 232, a filter and dryer unit 233 and a pneumatic actuator 234. The air outlet end of the air compressor 231 is connected to the air inlet end of the air storage tank 232 through a pipeline. The filter and dryer unit 233 includes an air inlet end and an air outlet end. The air inlet end of the filter and dryer unit 233 is connected to the air outlet end of the air storage tank 232 through a pipeline. The air outlet end of the filter and dryer unit 233 is connected to the input end of the pneumatic actuator 234 through a pipeline. The transmission component 240 is connected to the output end of the pneumatic actuator 234.

[0051] Specifically, in this embodiment, an air compressor 231 serves as the power source, mechanically compressing atmospheric air into high-pressure gas. The compressed air is then piped to an air tank 232 for storage. Air tank 232 stores the high-pressure air generated by compressor 231, ensuring a stable and continuous supply of air power when needed. Air tank 232 serves to store compressed air, stabilize system pressure, buffer airflow fluctuations, and separate moisture and impurities from the compressed air. A filter-dryer unit 233 purifies and dries the high-pressure air output from air tank 232. This unit can utilize existing, mature equipment, such as an adsorption dryer, to ensure clean and dry air entering pneumatic actuator 234. In a preferred embodiment, this unit utilizes a pneumatic triplex consisting of a filter, a pressure reducing valve, and an oil mist collector. After passing through the air tank, the compressed air passes through this triplex to further filter impurities, regulate pressure, and add lubricating oil mist, providing clean, stable, and well-lubricated compressed air for the pneumatic equipment. The pneumatic actuator 234 uses the pressure energy of high-pressure air to convert the pressure energy into mechanical energy through an internal mechanical structure. The converted mechanical energy is transmitted to the compression cover 220 through the transmission assembly 240, driving it to move along the inner wall of the pool body 210.

[0052] Furthermore, the tank body 210 includes a tank body 211 and a fixed frame 212 mounted on top of the tank body 211, and the pneumatic actuator 234 is mounted on the fixed frame 212. Specifically, the tank body 211 is the main part for storing water, and the fixed frame 212 serves to support and fix other equipment. The pneumatic actuator 234 is mounted on the fixed frame 212 to ensure its stability.

[0053] As a preferred embodiment, the pneumatic actuator 234 is a pneumatic motor, and the transmission assembly 240 includes a vertical rack 241 and a gear 242 connected to the output end of the pneumatic motor. The vertical rack 241 and the gear 242 are engaged, and the bottom end of the rack is connected to the compression cover 220.

[0054] Specifically, the pneumatic actuator 234 of this embodiment is a pneumatic motor, which features fast response, high torque, and smooth operation. It receives high-pressure air from the air energy supply assembly and converts the air's pressure energy into mechanical energy. The output end of the pneumatic motor is connected to a gear 242 (e.g., via a key). When the motor is operating, it drives the gear 242 to rotate, which then meshes with a vertical rack 241, converting the rotational motion of the gear 242 into linear motion of the vertical rack 241. In a preferred embodiment, the pneumatic motor can rotate forward and reverse, driving the compression cap 220 to rise or fall, thereby adjusting the water level within the tank body 210. For example, when the pneumatic motor rotates reversely, the tank body 210 and the compression cap 220 act like syringe pistons, pumping water from the lock chamber 110 into the tank body 210. As long as the water level in the water-saving tank can meet the changing water level in the lock chamber 110, water conservation can be achieved, addressing the limited water conservation issues of existing water-saving ship locks.

[0055] As another preferred embodiment, it also includes two balancing weight assemblies 260 respectively arranged on both sides of the pool body 211, each of the balancing weight assemblies 260 includes a first fixed pulley assembly 261, a second fixed pulley assembly 262, a third fixed pulley assembly 263, a steel wire rope 264 and a plurality of weights 265 stacked vertically in sequence, the first fixed pulley assembly 261 is installed on the top surface of the pool body 211, the second fixed pulley assembly 262 is installed on the inner wall of the pool body 211, and the third fixed pulley assembly 263 is installed on the outer wall of the pool body 211, one end of the steel wire rope 264 is connected to the top of the compression cover 220, and the other end is connected to the topmost weight 265 after winding around the second fixed pulley assembly 262, the first fixed pulley assembly and the third fixed pulley assembly in sequence.

[0056] Specifically, in this embodiment, the balancing weight assemblies 260 are located on both sides of the tank body 211, with one set on each side. Each balancing weight assembly 260 includes a first fixed pulley assembly 261, a second fixed pulley assembly 262, a third fixed pulley assembly 263, a steel wire rope 264, and a plurality of weights 265 stacked vertically. One end of the steel wire rope 264 is connected to the top of the compression cover 220, and the other end is guided sequentially through the second fixed pulley assembly 262, the first fixed pulley assembly 261, and the third fixed pulley assembly 263 before ultimately connecting to the topmost weight 265. When the pneumatic actuator 234 (e.g., a pneumatic motor) drives the compression cover 220 up and down, the steel wire rope 264 is retracted and extended, driving the weights 265 up and down in the vertical stacking direction. The weight of the weights 265 can be pre-designed or determined through preliminary testing.

[0057] It should be noted that the balancing weight assembly 260 can not only provide the necessary balancing force during the movement of the compression cover 220 to ensure that the compression cover 220 moves smoothly along the inner wall of the pool body 210, but also provide power during the rising process of the compression cover 220 to reversely pump the water in the gate chamber 110 into the pool body 210.

[0058] It is understandable that in other embodiments, there may be multiple (even number) balancing weight assemblies 260 arranged symmetrically, and those skilled in the art may set the specific arrangement as needed.

[0059] As a preferred embodiment, it also includes a locking mechanism 270 located on the side of the vertical rack 241, the locking mechanism 270 includes a mounting base 271, a transverse driving cylinder 272 and a locking head 273, the mounting base 271 is connected to the fixed rack 212, the transverse driving cylinder 272 is installed on the mounting base 271, and the locking head 273 is provided with a latching tooth 274 matching the vertical rack 241; wherein, the transverse driving cylinder 272 drives the locking head 273 to move toward the vertical rack 241 and engage with the vertical rack 241 to lock the vertical rack 241, and the transverse driving cylinder 272 drives the locking head 273 away from the vertical rack 241 and disengages from the vertical rack 241 to release the vertical rack 241.

[0060] Specifically, in this embodiment, the locking mechanism 270 is composed of three parts: a mounting base 271, a transverse driving cylinder 272, and a locking head 273. The mounting base 271 serves as the supporting structure of the entire locking mechanism 270 and is connected to the fixed rack 212 to ensure the stability of the locking mechanism 270. The transverse driving cylinder 272 is mounted on the mounting base 271 and drives the locking head 273 to move transversely. The locking head 273 is provided with latching teeth 274 that match the vertical rack 241. These latching teeth 274 can engage with the tooth grooves of the vertical rack 241 to lock or release the vertical rack 241. When the vertical rack 241 needs to be locked, the transverse driving cylinder 272 is started to drive the locking head 273 to move toward the vertical rack 241. As the locking head 273 approaches, the latching teeth 274 thereon gradually align with and mesh with the tooth grooves of the vertical rack 241, ultimately firmly locking the vertical rack 241 in its current position and preventing it from moving due to external forces, thereby ensuring that the current water level remains stable. When it is necessary to release the vertical rack 241, the horizontal drive cylinder 272 moves in the opposite direction, driving the locking head 273 away from the vertical rack 241. As the locking head 273 moves, the latching teeth 274 thereon gradually disengage from the tooth grooves of the vertical rack 241, thereby releasing the vertical rack 241 and allowing it to move freely.

[0061] As a good example, Figure 2As shown, each water-saving tank structure 20 is correspondingly provided with two pneumatic motors, and the vertical rack is provided with teeth on both sides, so that the transmission stability can be improved during the transmission process.

[0062] Furthermore, the water delivery assembly includes a water delivery valve opening and closing machine 251, a water delivery gate 253 connected to the bottom of the water delivery valve opening and closing machine, and a second horizontal water delivery corridor 252 arranged in a one-to-one correspondence with the first horizontal water delivery corridor 121. The second horizontal water delivery corridor 252 is connected to the first horizontal water delivery corridor 121. When the water delivery valve opening and closing machine 251 drives the water delivery gate 253 to move vertically to the lower limit position, the first horizontal water delivery corridor 121 is in a blocked state to prevent water from flowing between the pool body 210 and the gate chamber 110. When the water delivery valve opening and closing machine 251 drives the water delivery gate 253 to move vertically from the lower limit position upward, the first horizontal water delivery corridor 121 is in an unblocked state to allow water to flow between the pool body 210 and the gate chamber 110.

[0063] Specifically, such as Figure 1 As shown, through the control of the water supply valve opening and closing machine 251, the water supply valve opening and closing machine 251 can adopt the opening and closing machine commonly used in the ship lock, driving the water supply gate 253 to flexibly adjust the on-off state of different first horizontal water supply corridors 121, thereby realizing the control of water supply direction and water supply amount.

[0064] Please see the attached Figure 6 The present invention also provides a water supply control method for an air energy storage type water-saving ship lock, comprising the steps of:

[0065] S1, in response to the water supply request of the lock chamber 110, the air compressor 231, the air storage tank 232, the filter drying unit 233 and the air motor are started, and the air motor sequentially drives the gear 242 and the vertical rack 241, and then drives the gear 242 to move downward, so as to drive the water in the pool body 210 through the water delivery assembly and the first horizontal water delivery corridor 121 into the lock chamber 110 for water replenishment;

The preset water level can be determined according to the upstream water level, for example, the preset water level is set to be consistent with the upstream water level. When the real-time water level reaches the preset water level, it means that the lock chamber 110 has been replenished with the required amount of water and can be used for ship upstream. At this time, the horizontal drive cylinder 272 is started to drive the locking head 273 to move toward the vertical rack 241 and engage with it, locking the position of the vertical rack 241 to ensure the stability of the water level in the lock chamber 110.
