[0033] Obviously, the embodiments described above are only some embodiments of the utility model, not all embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the utility model.

[0034] In order to solve the problem of large water consumption of ship locks in the prior art, the utility model provides a high-head water-saving ship lock.

[0035] like Figures 1 to 11 As shown, the high-head water-saving ship lock includes a lock chamber 10, a retaining wall 20, an air storage tank 30 and an air pump 40. The lock chamber 10 is used for navigation of ships. The retaining wall 20 is arranged on one side of the lock chamber 10, and the retaining wall 20 is provided with an air storage chamber 21 and a first water storage chamber 22 arranged at intervals, and the first water storage chamber 22 is connected to the air storage chamber 21 and the lock chamber 10 in a switchable manner. There are multiple air storage tanks 30, and the first water storage chamber 22 is connected to multiple air storage tanks 30 in parallel and can be switched on and off. The air pump 40 is connected to the first water storage chamber 22 and the air storage chamber 21 respectively, and is used to inject or extract gas into the first water storage chamber 22 and / or the air storage chamber 21, and the air pump 40 is connected to the multiple air storage tanks 30 in parallel, and is used to inject or extract gas into the air storage tanks 30.

[0036] By setting up multiple gas tanks 30, maintaining the disconnection between the gas tank 30 and the first water storage chamber 22, using the air pump 40 to inject high-pressure gas into the first gas tank 30 until the preset pressure of the gas tank 30, stop injecting gas, and use the air pump 40 to draw the gas in the first gas tank 30 into the second gas tank 30, and continue to fill the pressure until the second gas tank 30 reaches the preset pressure, and then repeat the above operation until the gas in the last gas tank 30 reaches the preset pressure. At this time, the gas in the last gas tank 30 is passed into the gas storage chamber 21, and the air pump 40 is turned off to maintain the connection between the gas storage chamber 21 and the first water storage chamber 22, as well as the first water storage chamber 22 and the lock chamber 10. The gas in the gas storage chamber 21 is used to discharge the water in the first water storage chamber 22 into the lock chamber 10, so as to complete the water filling of the lock chamber 10 and raise the water level in the lock chamber 10, thereby facilitating the entry of ships in the lock chamber 10. Enter upstream or upstream ships enter the lock chamber 10; after completing the ship access, keep the connecting channel between the first water storage chamber 22 and the lock chamber 10 disconnected, and discharge the gas in the first water storage chamber 22 into multiple gas tanks 30 in sequence, then keep the connection between the first water storage chamber 22 and the lock chamber 10, press the water in the lock chamber 10 into the first water storage chamber 22, when the first water storage chamber 22 is full of water, close the connecting channel between the lock chamber 10 and the first water storage chamber 22, the water level of the lock chamber 10 drops, and the upstream ship enters the downstream or prepares for the downstream ship to enter the upstream, and the use of multiple parallel gas tanks 30 ensures that the water vapor exchange operation is simple and reliable. At the same time, the original water storage capacity is maintained in the first water storage chamber 22. The high-head water-saving ship lock of the present application can almost achieve zero water consumption for ships passing through the ship lock, thereby greatly reducing the water resource consumption of the ship lock when the ship passes.

[0037] like Figures 1 to 11 As shown, the retaining wall 20 is further provided with a second water storage chamber 23 , which is arranged above the air storage chamber 21 and is connected to the gate chamber 10 in an on-off manner.

[0038] Specifically, a fourth valve is provided at the bottom of the second water storage chamber 23. When the gate chamber 10 is filled with water, the fourth valve opens to discharge the water in the second water storage chamber 23 into the gate chamber 10. Optionally, there are multiple fourth valves, which are arranged at intervals at the bottom of the second water storage chamber 23.

[0039] Furthermore, the water level in the second water storage chamber 23 is higher than the water level in the gate chamber 10 , and gravity is used to allow the water in the second water storage chamber 23 to enter the gate chamber 10 through the fourth valve.

[0040] In this embodiment, there are multiple second water storage chambers 23, and the multiple second water storage chambers 23 are arranged at intervals along the height direction.

[0041] Specifically, among the plurality of second water storage chambers 23, the water level of the second water storage chamber 23 at the lowest position is greater than the water level of the gate chamber 10. Among the plurality of second water storage chambers, the second water storage chamber 23 at the lowest position releases water first to ensure that each second water storage chamber 23 can discharge water by the dead weight of the water. Optionally, the bottom of the second water storage chamber 23 is inclined or provided with an inclined plate, so as to facilitate the discharge of water in the second water storage chamber 23.

[0042] like Figures 1 to 11 As shown, the high-head water-saving ship lock further includes a first valve 50 , which is disposed at the connection point between the first water storage chamber 22 and the lock chamber 10 , and is used to control the connection between the first water storage chamber 22 and the air storage chamber 21 .

[0043] Specifically, the first valve 50 is made of pressure-resistant and corrosion-resistant materials to withstand the water pressure brought by the lock chamber 10 and the gas corrosion in the first water storage chamber 22, thereby improving the service life of the first valve 50. Optionally, a plurality of first valves 50 are provided, and the plurality of first valves 50 are arranged at intervals between the first water storage chamber 22 and the lock chamber 10. Each time a different first valve 50 is opened, a fatigue of the equipment caused by the long-term use of a single first valve 50 is reduced.

[0044] like Figures 1 to 11 As shown, the high-head water-saving ship lock further includes a first connecting pipeline 60 , which is communicated with the first water storage chamber 22 and the lock chamber 10 respectively, and the first valve 50 is arranged on the first connecting pipeline 60 .

[0045] Specifically, the first connecting pipe 60 is disposed at the bottom of the first water storage chamber 22 and the lock chamber 10, so that an approximately U-shaped pipe structure is formed between the first water storage chamber 22 and the lock chamber 10, so as to facilitate filling water into the lock chamber 10. Optionally, the first connecting pipe 60 is made of a corrosion-resistant material and cast at the bottom of the lock chamber 10.

[0046] like Figures 1 to 11 As shown, the high-head water-saving ship lock further includes a second valve 70 , which is disposed at the connection point between the first water storage chamber 22 and the air storage chamber 21 , and is used to control the connection between the first water storage chamber 22 and the air storage chamber 21 .

[0047] Specifically, the second valve 70 is made of corrosion-resistant material. Optionally, the first valve 50, the second valve 70 and the fourth valve are all solenoid valves for precise control.

[0048] like Figures 1 to 11 As shown, the high-head water-saving ship lock also includes a second connecting pipeline 80 and a third connecting pipeline 90. The second connecting pipeline 80 is respectively connected to the air outlet of the air pump 40 and the air storage chamber 21, and the third connecting pipeline 90 is respectively connected to the air inlet of the air pump 40 and the first water storage chamber 22.

[0049] Specifically, the air pump 40 pre-stores a large amount of gas, and injects gas into the air storage chamber 21 through the second connecting pipeline 80. When the gas in the air storage chamber 21 reaches the design pressure P, the gas injection is stopped. The design pressure of the air storage chamber 21 is greater than the pressure of the air. In this way, it can be ensured that after the gas injected into the air storage chamber 21 enters the first water storage chamber 22, the water stored in the first water storage chamber 22 can be pressed into the lock chamber 10. When the first water storage chamber 22 is pumped with negative pressure, the gas in the first water storage chamber 22 enters the air pump 40 along the air inlet of the air pump 40 through the third connecting pipeline 90, and is re-pressed into the air storage chamber 21 by the air pump 40, or is sent to the air storage tank 30.

[0050] like Figures 1 to 11 As shown, the high-head water-saving ship lock further includes a fourth connecting pipeline 100 , which is connected in parallel between the second connecting pipeline 80 and the third connecting pipeline 90 , and the second valve 70 of the high-head water-saving ship lock is arranged on the fourth connecting pipeline 100 .

[0051] Specifically, the fourth connecting pipeline 100 is connected to the second connecting pipeline 80 and the third connecting pipeline 90 by welding or integral molding to ensure the sealing between the connecting pipelines and prevent the safety hazard caused by the leakage of high-pressure gas. The second valve 70 is accommodated in the fourth connecting pipeline 100 .

[0052] Optionally, the two ends of the fourth connecting pipeline 100 are respectively connected to the air storage chamber 21 and the first water storage chamber 22, and the second connecting pipeline 80 and the third connecting pipeline 90 are respectively connected to the air storage chamber 21 and the first water storage chamber 22, which can be selected according to actual needs. At this time, the fourth connecting pipeline 100 is connected to the top of the first water storage chamber 22, and the gas in the air pump 40 is an inert gas that does not react with water and is not soluble in water. Through the above two settings, the inert gas in the air pump 40 enters along the top of the first water storage chamber 22, which is convenient for squeezing out the water in the first water storage chamber 22.

[0053] like Figures 1 to 11 As shown, the high-head water-saving ship lock also includes a third valve 120, which is arranged at the connection between the first water storage chamber 22 and the gas storage tank 30. There are multiple third valves 120, and the multiple third valves 120 are arranged in a one-to-one correspondence with the multiple gas storage tanks 30.

[0054] Specifically, the third valve 120 is also a solenoid valve. Each third valve 120 corresponds to a gas tank 30. When in use, the third valve 120 opens according to the instruction. The pressure bearing capacity of each gas tank 30 is different, and accordingly, the pressure bearing capacity of the third valve 120 is also different, so as to distinguish the order of inflation, which is also conducive to cost saving. Of course, multiple gas tanks 30 can also have the same pressure bearing capacity.

[0055] like Figures 1 to 11 As shown, the high-head water-saving ship lock further includes a fifth connecting pipeline 110 , which is respectively connected to the air pump 40 and the first water storage chamber 22 , and the air storage tank 30 and the third valve 120 are both arranged on the fifth connecting pipeline 110 .

[0056] Specifically, the gas tank 30 and the third valve 120 are both arranged on the fifth connecting pipeline 110, and the third valve 120 is located between the gas tank 30 and the first water storage chamber 22. Optionally, the high-head water-saving ship lock is further provided with a control room, in which a controller is arranged to control the opening and closing of multiple valves. A pressure display instrument may also be arranged on the gas tank 30 and electrically connected to the controller. When the pressure of the gas tank 30 reaches a threshold value, the controller controls the air pump 40 to be closed.

[0057] From the above description, it can be seen that the above-mentioned embodiment of the utility model achieves the following technical effects: by setting a high-head water-saving ship lock including a lock chamber 10, a retaining wall 20, an air storage tank 30 and an air pump 40, the lock chamber 10 is used for ship navigation, the retaining wall 20 is arranged on one side of the lock chamber 10, the retaining wall 20 is provided with an air storage chamber 21 and a first water storage chamber 22 arranged at intervals, the first water storage chamber 22 is respectively connected to the air storage chamber 21 and the lock chamber 10 in a switchable manner, there are multiple air storage tanks 30, the first water storage chamber 22 is connected in parallel with multiple air storage tanks 30 and can be switched on and off, the air pump 40 is respectively connected to the first water storage chamber 22 and the air storage chamber 21 for supplying water to the first water storage chamber 22. A water storage chamber 22 and / or a gas storage chamber 21 is injected or extracted, and an air pump 40 is connected in parallel with a plurality of gas storage tanks 30 to inject or extract gas into the gas storage tank 30. By setting a plurality of gas storage tanks 30, the gas storage tank 30 and the first water storage chamber 22 are disconnected. After the air pump 40 is used to inject high-pressure gas into the first gas storage tank 30 to a preset pressure of the gas storage tank 30, the gas injection is stopped, and the gas in the first gas storage tank 30 is pumped into the second gas storage tank 30 by the air pump 40, and the filling pressure is continued until the second gas storage tank 30 reaches the preset pressure, and then the above operation is repeated until the gas in the last gas storage tank 30 reaches The preset pressure is set, at this time, the gas in the last gas tank 30 is passed into the gas storage chamber 21, the air pump 40 is turned off, the connection between the gas storage chamber 21 and the first water storage chamber 22 and the first water storage chamber 22 and the lock chamber 10 is maintained, and the water in the first water storage chamber 22 is discharged into the lock chamber 10 by using the gas in the gas storage chamber 21, the lock chamber 10 is filled with water, and the water level in the lock chamber 10 is increased, thereby facilitating the ships in the lock chamber 10 to enter the upstream or the upstream ships to enter the lock chamber 10; after the ship access is completed, the connecting channel between the first water storage chamber 22 and the lock chamber 10 is kept disconnected, and the gas in the first water storage chamber 22 is discharged into multiple gas tanks 30 in sequence, Subsequently, the connection between the first water storage chamber 22 and the lock chamber 10 is maintained, and the water in the lock chamber 10 is pressed into the first water storage chamber 22. When the first water storage chamber 22 is full of water, the connecting passage between the lock chamber 10 and the first water storage chamber 22 is closed, and the water level in the lock chamber 10 drops, so that upstream ships can enter downstream or prepare for downstream ships to enter upstream.
