Description

Technical Field

[0001] This invention relates to the field of lock structure technology in water transport engineering, and in particular to a lock water conveyance system with integrated energy transfer and its operation method. Background Technology

[0002] Water-saving locks have the function of saving water consumption for ships passing through locks and reducing working head. A water-saving lock refers to a lock chamber with a water-saving pool on one or both sides. The water-saving pool stores part of the water flow when the lock chamber is discharged, and this water is pumped back into the lock chamber when needed later, thereby reducing the need to pump water from external water sources. By recycling the water in the water-saving pool, the total amount of water required for ships to pass through the lock can be significantly reduced.

[0003] Theoretically, for a given area of ​​the water-saving pool in a water-saving lock, the more water-saving pool stages there are, the higher the water-saving efficiency. However, in practice, the water-saving efficiency does not significantly increase after the number of water-saving pool stages exceeds three. In engineering, the water-saving rate of open-type water-saving locks is generally only 40% to 70%. Therefore, the actual water saving of current water-saving locks is still limited. For example, during the downstream process of a ship, after the water level in the lock chamber is level with the water level in the water-saving pool, the remaining water in the lock chamber needs to be discharged downstream until the water level in the lock chamber is level with the water level in the downstream approach channel; during the upstream process of a ship, water also needs to be supplied from upstream. It can be seen that the existing water-saving locks have a low water-saving rate and have not completely solved the water supply problem.

[0004] Currently, publicly available solutions for improving water-saving rates in ship locks mainly fall into two categories: mechanically driven disc-compressed water and air-compressed water. Regarding mechanically driven disc-compressed water, patent CN119162978A discloses an air-storage type water-saving ship lock and its control method, while patent CN115961602A discloses a vertical shaft type water-saving ship lock with an inflatable airbag. The devices in these patents all involve complex mechanical structures. Mechanical components (such as gears, lead screws, and hydraulic cylinders) are subjected to heavy loads over long periods, making them prone to wear or fatigue. The gas seal between the compression device and the water-saving pool directly affects the device's efficiency. Furthermore, the water-saving pool requires a regular circular horizontal cross-section, increasing construction difficulty. Regarding compressed water, patent CN117822537A discloses a low-head, zero-water-consumption lock with multi-stage air storage tanks and its operation method. This requires the water-saving pool, air storage chamber, and gas exchange chamber to be separated by partition walls and arranged vertically in a close manner. The water-saving pool at the top is lower than the highest water level in the lock chamber, while the water level in the water-saving pool at the bottom is higher than the lowest water level in the lock chamber. This places requirements on both the chamber structure and water level, increasing the difficulty of construction and operation. Secondly, during the lock chamber filling process, a high-pressure air pump needs to inject high-pressure gas into the air storage chamber; during the lock chamber discharge process, gas from the water-air exchange chamber needs to be drawn into the air storage chamber. The high-pressure air pump operates continuously during ship passage through the lock and requires additional external power. It is evident that existing water-saving locks and related technologies still suffer from high construction and operation difficulties and high energy consumption. Summary of the Invention

[0005] Purpose of the invention: The purpose of this invention is to provide a water conveyance system for a lock that integrates transportation and energy, and its operation method, to solve the problems of high construction and operation difficulty and high energy consumption of existing water-saving locks. This invention proposes a lock water conveyance system with a simple structure that reduces the complexity of construction and operation, while simultaneously recycling energy to achieve deep integration of transportation and energy.

[0006] Technical solution: The present invention provides a lock water conveyance system with energy fusion, including a lock chamber, and further including a lock water conveyance device, a water storage chamber and a compressed air energy storage system connected in sequence.

[0007] When the gate chamber is filled with water, the compressed air energy storage system releases high-pressure gas from the high-pressure storage tank into the water storage chamber, which squeezes the water in the water storage chamber into the gate chamber, thus completing the filling process and converting the energy of the compressed air into the potential energy of the water in the gate chamber.

[0008] When the gate chamber is released, the water in the gate chamber flows into the water storage chamber and compresses the gas in the water storage chamber into the high-pressure air tank, thus completing the water release and converting the potential energy of the water in the gate chamber into compressed air energy.

[0009] Furthermore, the compressed air energy storage system also includes an exhaust pipe and an inflation pipe, wherein the inflation pipe is a one-way gas supply pipe from the high-pressure gas storage tank to the water storage energy chamber; and the exhaust pipe is a one-way gas supply pipe from the water storage energy chamber to the high-pressure gas storage tank.

[0010] Furthermore, the exhaust pipe is also equipped with an exhaust valve, and the inflation pipe is also equipped with an inflation valve.

[0011] Furthermore, the compressed air energy storage system also includes an air turbine generator, a renewable energy compensation device, and an air compressor;

[0012] When the lock chamber is filled with water, the high-pressure gas tank releases high-pressure gas to compress the water storage chamber. The water in the water storage chamber enters the lock water conveying device through the water conveying pipe, and then enters the lock chamber through the lock water conveying device.

[0013] When water is released from the gate chamber, the gas in the water storage chamber is compressed into the high-pressure gas storage tank by the air compressor; the air turbine generator is used to convert the gas into electrical energy and power the air compressor; the renewable energy compensation device is used to utilize the collected new energy and compensate the air compressor for power supply.

[0014] Furthermore, the water storage chamber can be configured with an irregular shape according to actual geological conditions.

[0015] Furthermore, one or more water storage chambers can be installed, and multiple water storage chambers can be connected or disconnected through valves.

[0016] Furthermore, a lock water conveyance device is provided at the bottom of the lock chamber. The lock water conveyance device consists of a water conveyance corridor and several outlet branches. The lock chamber is connected to the water storage chamber through a water conveyance pipe connected to the water conveyance corridor.

[0017] The operation method of the energy-integrated lock water conveyance system of the present invention includes the following steps:

[0018] When the lock is filled with water, the compressed gas in the high-pressure gas storage tank is transferred to the water storage chamber, and the water in the water storage chamber enters the lock water supply device through the water supply pipeline and finally flows into the lock chamber.

[0019] When the lock releases water, the water in the lock chamber flows continuously into the water storage chamber through the lock's water conveying device and water conveying pipeline under the effect of the water level difference. The gas in the water storage chamber is compressed and enters the high-pressure gas storage tank.

[0020] Furthermore, when the lock is filled with water, the high-pressure gas stored in the high-pressure gas tank enters the water storage chamber through the gas filling pipeline. Under the action of the high-pressure gas, the water flows to the lock chamber through the water conveying pipeline and the lock water conveying device. The water level in the lock chamber rises. When the first preset condition is met, the upstream gate is opened and the ship passes through the lock upstream.

[0021] When the lock is released, the water in the lock chamber is released into the water storage chamber, and the water level in the lock chamber drops. Under the action of the water level difference, the gas stored in the water storage chamber enters the high-pressure gas storage tank through the exhaust pipe. When the second preset condition is met, the downstream gate is opened and the ship passes through the lock to go downstream.

[0022] The inflation pipeline is a one-way gas supply pipeline from the high-pressure gas storage tank to the water storage energy chamber; the exhaust pipeline is a one-way gas supply pipeline from the water storage energy chamber to the high-pressure gas storage tank.

[0023] Furthermore, the first preset condition is the real-time pressure of the water storage tank. The second preset condition is the real-time pressure of the water storage tank. = ;in:

[0026] Beneficial effects: Compared with the prior art, the advantages of the present invention are: The water storage energy chamber of the present invention can realize the conversion of the potential energy of the water in the lock chamber and the energy of compressed air, realize the energy recycling, and complete the deep integration of transportation and energy. Specifically, it has the following advantages: (1) The air compressor of the present invention only operates during the water discharge of the lock chamber, and the potential energy of the water in the lock chamber is converted into compressed air energy.

[0034] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0035] Example 1

[0036] The energy-integrated lock water conveyance system of the present invention includes a lock chamber 2, a water storage chamber 5 and a compressed air energy storage system 7 connected in sequence;

[0037] When the gate chamber 2 is filled with water, the compressed air energy storage system 7 releases the high-pressure gas in the high-pressure storage tank 13 into the water storage energy storage chamber 5, which squeezes the water in the water storage energy storage chamber 5 into the gate chamber 2, completing the filling process and converting the energy of the compressed air into the potential energy of the water in the gate chamber.

[0038] When the gate chamber 2 is releasing water, the water in the gate chamber 2 flows into the water storage chamber 5 and compresses the gas in the water storage chamber 5 into the high-pressure air storage tank 13, thus completing the water release and converting the potential energy of the water in the gate chamber into compressed air energy.

[0039] Specifically, such as Figures 1-2 As shown, the lock water conveyance device 1 is used to fill and drain the lock chamber to overcome the water level difference and enable ships to pass through the lock. Its main components include a water conveyance corridor 3 and outlet branch holes 4. Several outlet branch holes 4 are provided at the top of the water conveyance corridor 3. The lock chamber 2 is connected to the water storage chamber 5 via a water conveyance pipe 6. The type of water conveyance system for the lock water conveyance device 1 is not limited; it only requires connecting the lock chamber 2 and the water storage chamber 5 via the water conveyance pipe 6.

[0040] Specifically, the water storage and energy storage chamber 5 has the functions of water storage and energy storage. The water storage function is manifested in storing the outflow water of the lock when the lock chamber is discharged; the energy storage function is manifested in storing the high-pressure gas of the high-pressure gas storage tank when the lock chamber is filled with water.

[0041] In some optional embodiments, one or more water storage chambers 5 may be provided, and multiple water storage chambers may be connected or disconnected by valves.

[0042] In some alternative embodiments, such as Figure 2 As shown, the water storage chamber 5 can be set with an irregular shape according to the actual geological conditions.

[0043] Specifically, such as Figure 1 As shown, the compressed air energy storage system 7 is used for power generation and energy storage, including an exhaust pipe 8, an exhaust valve 9, an air turbine generator 10, a renewable energy compensation device 11, an air compressor 12, a high-pressure air tank 13, an air charging valve 14, and an air charging pipe 15. During operation, water from the water storage chamber should be prevented from entering the exhaust pipe of the compressed air energy storage system 7, otherwise corrosion will be accelerated under high pressure. Both the air charging and exhaust pipes are unidirectional. The air charging pipe 15 is a unidirectional air supply pipe from the high-pressure air tank to the water storage chamber, and the exhaust pipe 8 is a unidirectional air supply pipe from the water storage chamber to the high-pressure air tank. Furthermore, the entire air supply pipeline is connected by welding or integral molding to ensure the sealing between the connecting pipes and prevent high-pressure gas leakage from causing safety hazards.

[0044] Specifically, when the lock chamber 2 is filled with water, the high-pressure gas storage tank 13 releases high-pressure gas to compress the water storage energy chamber 5. The water in the water storage energy chamber 5 enters the lock water conveying device 1 through the water conveying pipe 6, and further enters the lock chamber 2 through the water conveying corridor 3 at the bottom of the lock chamber 2 and the outlet branch hole 4. When the lock chamber 2 is discharged, the high-pressure gas in the water storage energy chamber 5 is compressed into the high-pressure gas storage tank 13 by the air compressor 12. The air turbine generator 10 is used to generate electricity using the passed high-pressure gas and power the air compressor 12. The renewable energy compensation device 11 is used to collect new energy sources and power the air compressor 12. Furthermore, the renewable energy compensation device 11 can connect unstable new energy sources such as solar energy and wind energy to the air compression energy storage system 7 to compensate for the energy loss during the lock filling and discharging process.

[0045] Furthermore, an exhaust valve 9 is provided on the exhaust pipe 8, and an inflation valve 14 is provided on the inflation pipe 15. The exhaust valve 9 and the inflation valve 14 can be used together to connect or block the exhaust pipe.

[0046] Example 2

[0047] The operation method of the energy-integrated lock water conveyance system described in Embodiment 1 of the present invention includes the following steps:

[0048] When the lock is filled with water, the compressed gas in the high-pressure gas storage tank is transferred to the water storage energy chamber, and the water in the water storage energy chamber enters the lock chamber; when the lock is discharged water, under the action of the water level difference, the water in the lock chamber continuously flows into the water storage energy chamber, and the gas in the water storage energy chamber is compressed and enters the high-pressure gas storage tank.

[0049] Specifically, such as Figure 3 As shown, the ship passage scheduling of the lock water conveyance system of the present invention is divided into lock chamber filling and water discharge. The specific steps of filling and discharging water are described below.

[0050] (1) When the lock is filled with water, the gas stored in the high-pressure gas tank enters the water storage chamber through the gas filling pipeline. Under the action of the high-pressure gas, the water flows to the lock chamber through the lock water conveyance system. The water level in the lock chamber rises. When the first preset condition is met, the upstream gate is opened and the ship passes through the lock upstream. The operation steps are as follows.

[0051] 1a) Open the inflation valve 14 and close the deflation valve 9;

[0052] 1b) The high-pressure gas from the high-pressure gas storage tank 13 enters the water storage chamber 5 through the gas filling pipeline 15;

[0053] 1c) Under the action of high-pressure gas, the water level in the water storage chamber drops, and the water enters the gate chamber water conveying device 1 through the water conveying pipe 6, and then flows into the gate chamber through the water conveying pipe 6 at the bottom of the gate chamber 2 and the water outlet branch hole 4, thereby raising the water level in the gate chamber.

[0054] 1d) Calculate the water surface pressure in the reservoir at the moment the gate chamber filling ends. ;

[0055] 1f) Continuously monitor the real-time water level of the gate chamber and the real-time water pressure at the water surface of the water storage tank. ;

[0056] 1g) If the real-time pressure of the water storage chamber is = If the water level in the sluice chamber reaches the level required to open the upstream navigation route, then the sluice chamber will continue to be filled with water until the water level rises. The water level in the water storage tank dropped. ;

[0057] 1h) When the water level in the sluice chamber is level with the upstream (i.e. = (This can open the upstream gate, allowing ships to pass through the lock upstream and complete the upstream passage through the lock.)

[0058] 2) When the lock releases water, water flows from the lock chamber into the energy storage chamber, causing the water level in the lock chamber to drop. Under the influence of this water level difference, the gas stored in the energy storage chamber enters the high-pressure gas storage tank through the exhaust pipe. When the second preset condition is met, the downstream gate opens, allowing ships to pass through the lock downstream. The operating steps are as follows:

[0059] 2a) Open the exhaust valve 9 and close the inflation valve 14;

[0060] 2b) The water in the lock chamber 2 enters the water conveyance pipe 6 through the outlet branch hole 4 and the water conveyance corridor 3 in the lock water conveyance device 1, and continuously discharges water into the water storage chamber 5. The water level in the lock chamber drops and the water level in the water storage chamber rises.

[0061] 2c) Under the influence of the potential energy of the water in the gate chamber, the gas in the upper part of the water storage chamber 5 moves unidirectionally along the exhaust pipe 8 and the air turbine generator 10; under the action of the air compressor 12, it continuously enters the high-pressure air storage tank 13 for storage and standby.

[0062] 2d) Calculate the water surface pressure in the reservoir at the moment the gate discharge ends. ;

[0063] 2f) Continuously monitor the real-time water level in the gate chamber and the real-time water pressure at the water surface in the reservoir. ;

[0064] 2g) If the real-time pressure of the water storage chamber is = If the water level in the sluice chamber reaches the level required to open the downstream gate for navigation, then the sluice chamber will continue to release water until the water level drops. The water level in the water storage tank rose. ;

[0065] 2h) When the water level in the sluice chamber is level with the downstream (i.e. = This allows the downstream gates to be opened, enabling vessels to pass through the lock and facilitating vessel passage scheduling.

[0066] Furthermore, referring to Figure 4 The water surface pressure in the water storage chamber described in steps 2d) and 1d) can be calculated using the following formulas:

[0067]

[0068] in The initial water level before the sluice chamber is filled with water. The initial water level in the energy storage chamber before the gate chamber is filled with water. The water level in the gate chamber after filling is completed, in meters (m). The density of water, in g / cm³ 3 ; Acceleration due to gravity, unit m / s² 2 ; The area of ​​the base of the gate chamber, in meters. 2 ; The area of ​​the water storage energy chamber is expressed in meters (m²). 2 .

[0069] Example 3

[0070] This embodiment describes the derivation process of the water surface pressure in the water storage chamber in Embodiment 2. Since the filling and emptying of the gate chamber is the reverse process of water level change, this embodiment only describes the derivation process of the water surface pressure before and after the water storage chamber is filled into the gate chamber.

[0071] Reference Figure 4 ,definition The volume of water exchanged between the gate chamber and the water storage chamber during filling. Before filling the gate chamber, This refers to the initial water surface pressure in the water storage chamber. This represents the initial water level in the water storage chamber. This is the initial water level of the sluice chamber; after the sluice chamber is filled with water, This refers to the height by which the water level in the energy storage chamber drops after filling is complete. This refers to the real-time pressure of the water storage tank. This refers to the height by which the water level in the gate chamber rises after the filling process is completed. Let be the water level in the gate chamber at time t. Clearly, the water level rises by a certain height during the filling process. .

[0072] 1) Assuming the cross-sectional area of ​​the water storage chamber is uniform in the vertical direction (shape is not required), then based on the geometric relationship and operating characteristics of the gate chamber and the water storage chamber:

[0073]

[0074] 2) Calculate the working head of the water storage chamber:

[0075]

[0076] 3) According to the principle of isobaric surfaces, the initial water surface pressure in the energy storage chamber before the gate chamber is filled with water is:

[0077]

[0078] 4) According to the principle of isobaric surfaces, the water surface pressure in the storage chamber after the gate chamber is filled with water is:

[0079]

[0080] 5) Further processing yielded:

[0081]

[0082] The above formulas can be used to predict the surface pressure of the water storage chamber under different working heads of the lock.

[0083] Example 4

[0084] This embodiment verifies the energy-integrated lock water conveyance system and its operation method described in this invention through specific experiments. This embodiment assumes that the cross-sectional area of ​​the water storage chamber is uniform in the vertical direction (shape is not required), and takes the water filling stage of the lock chamber as an example for the experiment.

[0085] A lock has a working head of 20m, an upstream water level of 30m, and a downstream water level of 10m. Before filling, the initial water level in the lock chamber is 10m, and after filling, the water level in the lock chamber is 30m. The water storage chamber has an initial water level of 10m before filling, and after filling, the water level is -10m.

[0086] Figure 5 and Figure 6 This demonstrates the water level changes in the reservoir and gate chamber at a working head of 20m. After filling, the water levels in the reservoir and gate chamber are level, i.e. (Pa), therefore, it is only necessary to monitor the water level in the gate chamber in real time and substitute it. This allows us to determine the water surface pressure in the water storage chamber. Figure 7 The line represents the pressure process of the water storage chamber during the lock chamber filling stage. The dashed line indicates the end of the lock chamber filling process, which can be used as the basis for the lock water conveyance system's passage scheduling when the working head is 20m. Since the lock discharge stage is similar to the filling stage, it will not be described in detail here.
