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 resources are particularly precious in areas where water resources are scarce or in canal areas where pumping costs are high (such as the Hunan-Guangxi Canal and the Pinglu Canal). A water-saving ship lock is a lock with a water-saving tank on one or both sides of the lock chamber. The water-saving tank is used to receive part of the water flow when the lock chamber is released, and then refill the water back into the lock chamber when needed, thereby reducing the need to pump water from external water sources. By recycling the water in the water-saving tank, the total amount of water required for the passage of ships 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 downstream, 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 downstream.

[0004] When a ship needs to sail from downstream to upstream (upward), the water in the water-saving tank must first be collected 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 in 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 by building 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 move upstream.

[0005] Therefore, the actual water resources saved by the existing water-saving ship locks are still limited. For example, after the water level in the lock chamber is flush with the water level in the water-saving pool during the downstream process, it is necessary to continue to discharge the water in the lock chamber to the downstream until it is flush with the downstream water level. During the upward process, water needs to be supplied from the upstream or water needs to be diverted from a new reservoir outside the water-saving pool. The existing water-saving ship locks have not completely solved the water shortage problem, and the construction of new reservoirs involves a wide range of areas, large engineering workload, and high cost. The water diversion system involves a wider range of areas, involving a series of issues such as reservoir site selection, foundation waterproofing, and channel 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

Therefore, the features defined as "first" and "second" may explicitly or implicitly include at least one of the features. In addition, the technical solutions between the various embodiments can be combined with each other, but they must be based on the ability of ordinary technicians in the field to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0043] Please refer to the attached Figures 1 to 5 An air energy storage water-saving ship lock in one embodiment of the present invention comprises a ship lock main structure 10 and a water-saving tank structure 20 arranged on the side of the ship lock main structure 10, wherein the ship lock main structure 10 comprises a first transverse water delivery gallery 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 component (not shown in the figure), a transmission component 240 and a water delivery component (not shown in the figure). The tank body 210 is provided with a connecting hole (not shown in the figure) through which the water delivery component passes. One end of the water delivery component is connected to the tank body 210 through the connecting hole, and the other end of the water delivery component is connected to the transverse water delivery component. The compression cover 220 is movable along the inner wall of the tank body 210 and is in active sealing contact with the inner wall of the tank body 210. The top of the compression cover 220 is connected to the transmission component 240, and the transmission component 240 is connected to the air energy supply component. The compression cover 220 has a downward state and an upward state in 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 transverse 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 transverse water delivery corridor 121 and the water delivery component.

[0046] Specifically, when the ship needs to sail from downstream to upstream (upward), the air energy supply component (such as an air compressor or a starting pump) starts to work, generating 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] On the contrary, when the lock chamber 110 needs to lower the water level to facilitate the ship to go down, the air energy supply assembly can work in reverse or according to the balance weight assembly 260 provided later, the transmission assembly 240 drives the compression cover 220 to move up along the inner wall of the tank body 210 and enter the upward state. At this time, due to the pressure difference, the water in the lock chamber 110 flows back to the water delivery assembly through the first transverse water delivery corridor 121, and finally enters the tank body 210 for storage until it returns to the set liquid level (for example, the initial liquid level height). At this time, the water level in the lock chamber 110 drops to the same level as the downstream water level, and the ship can go down, and it can also prepare 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 respectively arranged 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 replenishment 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, which is 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 assembly 240 is connected to the output end of the pneumatic actuator 234.

[0051] Specifically, in this embodiment, the air compressor 231 is used as a power source, and the air in the atmosphere is mechanically compressed into high-pressure gas. The compressed air is transported to the air storage tank 232 through a pipeline for storage. The air storage tank 232 is used to store the high-pressure air generated by the air compressor 231 to ensure that the air source power can be stably and continuously provided when needed. The air storage tank 232 can store compressed air, stabilize the system pressure, buffer air flow fluctuations, and separate moisture and impurities in the compressed air. The filter drying unit 233 purifies and dries the high-pressure air output from the air storage tank 232. The filter drying unit 233 can use existing mature equipment, such as an adsorption dryer, to ensure that the gas entering the pneumatic actuator 234 is clean and dry. In a preferred example, the filter drying unit 233 uses a pneumatic triplet, which is composed of a filter, a pressure reducing valve and an oil mist. The compressed air treated by the air storage tank is further filtered by the pneumatic triplet, the pressure is adjusted, and lubricating oil mist is added, providing clean, stable and well-lubricated compressed air for the pneumatic equipment. The pneumatic actuator 234 utilizes 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 to drive it to move along the inner wall of the pool body 210.

[0052] Further, the pool body 210 includes a pool body 211 and a fixed rack 212 installed on the top of the pool body 211, and the pneumatic actuator 234 is installed on the fixed rack 212. Specifically, the pool body 211 is the main part of the water storage body, the fixed rack 212 plays the role of supporting and fixing other equipment, and the pneumatic actuator 234 is installed on the fixed rack 212 to ensure the stability of the pneumatic actuator 234.

[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 meshed, 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 has the characteristics of fast response, large torque, and stable operation. By receiving high-pressure air from the air energy supply component, the pressure energy of the air is converted into mechanical energy. The output end of the pneumatic motor is connected to the gear 242 (for example, it can be connected by a key). When the motor is working, it drives the gear 242 to rotate, and the gear 242 is meshed with the vertical rack 241 to convert the rotational motion of the gear 242 into the linear motion of the vertical rack 241. In a preferred embodiment, the pneumatic motor can rotate forward and reverse, and can drive the compression cover 220 to rise or fall, so as to achieve the adjustment of the water level in the pool body 210. For example, when the pneumatic motor is reversed, the pool body 210 and the compression cover 220 are in the form of a syringe piston, and the water in the lock chamber 110 can be pumped into the pool body 210. As long as the water in the water-saving pool can meet the demand for the change of the water level in the lock chamber 110, the purpose of water saving can be achieved, which solves the problem of limited water saving in the existing water-saving ship lock.

[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 wire rope 264 and a plurality of weights 265 stacked in sequence vertically, 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 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 being wound 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 assembly 260 is located on both sides of the pool body 211, and each side is provided with a set, and each set of 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 in sequence 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 by the second fixed pulley assembly 262, the first fixed pulley assembly 261 and the third fixed pulley assembly 263 in sequence, and finally connected to the topmost weight 265. When the pneumatic actuator 234 (such as a pneumatic motor) drives the compression cover 220 to move up and down, the steel wire rope 264 will be retracted and released accordingly, driving the weight 265 to rise or fall in the direction of vertical stacking. The weight of the weight 265 can be pre-designed or pre-tested to be determined.

[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 required.

[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, the locking mechanism 270 in this embodiment 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 a 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 to drive the locking head 273 to move transversely. The locking head 273 is provided with latch teeth 274 that match the vertical rack 241. These latch 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, and finally the vertical rack 241 is firmly locked in the current position and will not move due to external force, thereby ensuring that the current water level is in a stable state. When the vertical rack 241 needs to be released, the horizontal driving cylinder 272 moves in the opposite direction to drive 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 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 hoist 251, a water delivery gate 253 connected to the bottom of the water delivery valve hoist, and a second transverse water delivery corridor 252 arranged in a one-to-one correspondence with the first transverse water delivery corridor 121. The second transverse water delivery corridor 252 is connected to the first transverse water delivery corridor 121. When the water delivery valve hoist 251 drives the water delivery gate 253 to move vertically to the lower limit position, the first transverse 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 hoist 251 drives the water delivery gate 253 to move vertically from the lower limit position upward, the first transverse water delivery corridor 121 is in a unblocked state to allow water to flow between the pool body 210 and the gate chamber 110.

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

[0064] Please refer to the attached Figure 6 The present invention also provides a water supply control method for an air energy storage 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 pneumatic motor are started, and the pneumatic 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 to enter the lock chamber 110 through the water delivery assembly and the first horizontal water delivery corridor 121 to replenish water;

[0066] S2, obtaining the real-time water level in the lock chamber 110, and determining whether the real-time water level has reached the preset water level; the water level can be obtained by existing means, such as observing the water level height line on the inner wall of the lock chamber, or by real-time detection and acquisition through a water level sensor.

[0067] S3, when the real-time water level reaches the preset water level, the lateral driving cylinder 272 is started to drive the locking head 273 to move toward the vertical rack 241 and engage with the vertical rack 241 to lock the vertical rack 241.

[0068] Specifically, when the lock chamber 110 needs water supply, the air compressor 231, the air storage tank 232, the filter drying unit 233 and the pneumatic motor are started. After receiving the power, the pneumatic motor will drive the gear 242 and the vertical rack 241 to move in turn. During the water supply process, the real-time water level information in the lock chamber 110 is obtained in real time and compared with the preset water level. 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 the ship to go up. 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.
