[0029] 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.

[0030] In order to solve the problem of large water consumption of ship locks in the prior art, the utility model provides a water-saving ship lock.

[0031] like Figures 1 to 7 As shown, the water-saving ship lock includes a lock chamber 10, a retaining wall 20 and an air pump 30. 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 water storage chamber 22 arranged at intervals, and the water storage chamber 22 is connected to the air storage chamber 21 and the lock chamber 10 in a disconnectable manner. The air pump 30 is connected to the water storage chamber 22 and the air storage chamber 21, respectively, and is used to inject or extract gas into the air storage chamber 21 and / or the water storage chamber 22.

[0032] After a large amount of high-pressure gas is introduced into the air storage chamber 21 through the air pump 30, the air pump 30 is turned off. At this time, the communication between the water storage chamber 22 and the air storage chamber 21 and between the water storage chamber 22 and the lock chamber 10 is maintained, and the high-pressure gas in the air storage chamber 21 is used to press all the water stored in the water storage chamber 22 into the lock chamber 10, so that the water level in the lock chamber 10 is raised, so that the downstream ships can enter the upstream or the upstream ships can enter the lock chamber 10. Then, the communication channels between the water storage chamber 22 and the air storage chamber 21 and between the water storage chamber 22 and the lock chamber 10 are closed, and the air pump 30 is used to press the water stored in the water storage chamber 22 into the lock chamber 10. The water storage chamber 22 filled with gas is evacuated, and the evacuated gas is pressed into the gas storage chamber 21; after the vacuuming is completed, the lock chamber 10 and the water storage chamber 22 are connected, the water in the lock chamber 10 is pressed into the water storage chamber 22, and the water level in the lock chamber 10 drops to be flush with the downstream water level, completing the upstream ship entering the downstream or preparing for the next ship transportation; finally, the connecting channel between the water storage chamber 22 and the lock chamber 10 is closed to maintain the water storage volume in the water storage chamber 22. The water-saving ship lock of the present application can achieve almost zero water consumption, thereby greatly reducing the water resource consumption caused by the ship lock when the ship passes.

[0033] like Figures 1 to 7 As shown, the water-saving ship lock further includes a first valve 40 , which is disposed at the connection point between the water storage chamber 22 and the lock chamber 10 , and is used to control the connection between the water storage chamber 22 and the air storage chamber 21 .

[0034] Specifically, when the gas in the gas storage chamber 21 presses the water in the water storage chamber 22 into the gate chamber 10, the first valve 40 is quickly closed. The first valve 40 has a large pressure bearing capacity, even if there is a strong pressure on both sides of the first valve 40, such as Figure 4 and Figure 7As shown, the first valve 40 will not be deformed during operation of the water-saving ship lock, thereby causing the first valve 40 to be unable to be opened or closed. Optionally, the first valve 40 is made of an anti-corrosion material to increase the service life of the water-saving ship lock and reduce the frequency of valve replacement.

[0035] like Figures 1 to 7 As shown, the water-saving ship lock further includes a first connecting pipeline 50 , which is communicated with the water storage chamber 22 and the lock chamber 10 respectively, and the first valve 40 is disposed on the first connecting pipeline 50 .

[0036] Specifically, the first connecting pipeline 50 may be a connecting groove or a connecting pipe. When the first connecting pipeline 50 is a connecting pipe, the connecting pipe is made of corrosion-resistant materials such as alloy materials, and the first valve 40 is accommodated in the first connecting pipeline 50 .

[0037] In this embodiment, the first connecting pipeline 50 is communicated with the bottom of the water storage chamber 22 and the bottom of the gate chamber 10 respectively.

[0038] Specifically, the first connecting pipeline 50 is arranged at the bottom of the lock chamber 10 and the retaining wall 20, and the two ends of the first connecting pipeline 50 are respectively connected to the bottom of the retaining wall 20 of the lock chamber 10 so that the lock chamber 10 and the water storage chamber 22 form a structure similar to a U-shaped tube. When the water storage chamber 22 is filled with gas, the water in the water storage chamber 22 is pressed into the lock chamber through the first connecting pipeline 50. When the water storage chamber 22 is evacuated, the first valve 40 remains closed. After the evacuation is completed, the first valve 40 is opened, and the water in the lock chamber 10 quickly enters the water storage chamber 22 along the first connecting pipeline 50. Optionally, the first connecting pipeline 50 is cast at the bottom of the lock chamber 10 and the water storage chamber 22.

[0039] Furthermore, after the water in the water storage chamber 22 is pressed into the lock chamber 10 to complete the navigation of the ship, the water storage chamber 22 is evacuated, and the water filled in the lock chamber 10 is re-sucked into the water storage chamber 22 along the first connecting pipe 50, thereby ensuring the stability of the water storage amount in the water storage chamber 22, avoiding the consumption of water resources after the ship passes through the lock chamber 10, and ensuring the use of water-saving ship locks even in the dry season.

[0040] like Figures 1 to 7 As shown, the water-saving ship lock further includes a second valve 60 , which is disposed at the connection point between the water storage chamber 22 and the air storage chamber 21 , and is used to control the connection and disconnection between the water storage chamber 22 and the air storage chamber 21 .

[0041] Specifically, when the second valve 60 is in the first working state of the water-saving lock, that is, when the ship in the water-saving lock enters the upstream from the downstream, there is gas on both sides of the second valve 60; and in the second working state of the water-saving lock, that is, when a ship transportation is completed, there is high-pressure gas on one side of the second valve 60 and some water may exist on the other side, so the second valve 60 is also made of anti-corrosion material.

[0042] like Figures 1 to 7 As shown, the water-saving ship lock also includes a second connecting pipeline 70 and a third connecting pipeline 80. The second connecting pipeline 70 is respectively connected to the air outlet of the air pump 30 and the air storage chamber 21, and the third connecting pipeline 80 is respectively connected to the air inlet of the air pump 30 and the water storage chamber 22.

[0043] Specifically, the air pump 30 pre-stores a large amount of gas, and injects gas into the air storage chamber 21 through the second connecting pipeline 70. 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 water storage chamber 22, the water stored in the water storage chamber 22 can be pressed into the gate chamber 10. When the water storage chamber 22 is pumped with negative pressure, the gas in the water storage chamber 22 enters the air pump 30 along the air inlet of the air pump 30 through the third connecting pipeline 80, and is re-pressed into the air storage chamber 21 by the air pump 30.

[0044] like Figures 1 to 7 As shown, the water-saving ship lock further includes a fourth connecting pipeline 90 , which is connected in parallel between the second connecting pipeline 70 and the third connecting pipeline 80 , and the second valve 60 of the water-saving ship lock is arranged on the fourth connecting pipeline 90 .

[0045] Specifically, both ends of the fourth connecting pipeline 90 are connected to the second connecting pipeline 70 and the third connecting pipeline 80, and the gas in the gas storage chamber 21 enters the water storage chamber 22 through the second connecting pipeline 70, the fourth connecting pipeline 90 and the third connecting pipeline 80. Optionally, both ends of the fourth connecting pipeline 90 are connected to the gas storage chamber 21 and the water storage chamber 22, respectively, and the gas in the gas storage chamber 21 enters the water storage chamber 22 through the fourth connecting pipeline 90.

[0046] In this embodiment, the third connecting pipe 80 is in communication with the top of the water storage chamber 22 .

[0047] Specifically, the high-pressure gas in the gas storage chamber 21 is an inert gas that is insoluble in water and does not react with water, and the third connecting pipe 80 is connected to the top of the water storage chamber 22. The high-pressure gas gathers at the top of the water storage chamber 22, which is conducive to the high-pressure gas quickly pressing the water in the water storage chamber 22 into the gate chamber 10, so as to quickly complete the filling of the gate chamber 10. Of course, the third connecting pipe 80 can also be connected to other positions of the water storage chamber 22, which can be selected according to actual needs.

[0048] In this embodiment, the water-saving ship lock further includes a first valve 40 and a second valve 60, which are respectively arranged at the connection between the water storage chamber 22 and the lock chamber 10 and the air storage chamber 21, and the first valve 40 and the second valve 60 are both electric control valves.

[0049] Specifically, the first valve 40 and the second valve 60 are both electric control valves. The electric control valve configuration is beneficial for unified control of the first valve 40 and the second valve 60 , and is convenient for quick response.

[0050] In this embodiment, the water-saving ship lock further includes a controller, and the controller is electrically connected to the air pump 30 .

[0051] Specifically, a control room is provided on one side of the water-saving ship lock, and a controller is provided in the control room. The controller is electrically connected to the air pump 30, and the first valve 40 and the second valve 60. The controller can realize the automatic operation conversion of the air pump 30, from the gas injection operation to the gas suction operation, and the automatic opening and closing of the first valve 40 and the second valve 60. Optionally, the water-saving ship lock further includes a plurality of detectors, which are respectively arranged in the air storage chamber 21, the water storage chamber 22 and the lock chamber 10 to detect the gas in the air storage chamber 21 and the water levels in the water storage chamber 22 and the lock chamber 10.

[0052] From the above description, it can be seen that the above-mentioned embodiments of the utility model achieve the following technical effects: by setting a water-saving ship lock including a lock chamber 10, a retaining wall 20 and an air pump 30, the lock chamber 10 is used for ship navigation, 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 water storage chamber 22 arranged at intervals, and the water storage chamber 22 is respectively connected to the air storage chamber 21 and the lock chamber 10 in a disconnectable manner. The air pump 30 is connected to the water storage chamber 22 and the air storage chamber 21 respectively, and is used to inject or extract gas into the air storage chamber 21 and / or the water storage chamber 22. After a large amount of high-pressure gas is introduced into the air storage chamber 21 through the air pump 30, the air pump 30 is turned off, and the communication between the water storage chamber 22 and the air storage chamber 21 and between the water storage chamber 22 and the lock chamber 10 is maintained. The high-pressure gas in the air storage chamber 21 is used to press all the water stored in the water storage chamber 22 into the lock chamber 10, so that the water level in the lock chamber 10 is raised, so that the downstream ship can enter the upstream or the upstream ship can enter the lock chamber 10 easily. Then, the air pump 30 is closed between the water storage chamber 22 and the air storage chamber 21 and the water storage chamber 21. The communicating passage between the chamber 22 and the lock chamber 10 is used to evacuate the water storage chamber 22 filled with gas by using the air pump 30, and the evacuated gas is pressed into the air storage chamber 21; after the vacuuming is completed, the lock chamber 10 and the water storage chamber 22 are connected, the water in the lock chamber 10 is pressed into the water storage chamber 22, and the water level in the lock chamber 10 drops to be flush with the downstream water level, completing the upstream ship entering the downstream or preparing for the next ship transportation; finally, the communicating passage between the water storage chamber 22 and the lock chamber 10 is closed to maintain the water storage volume in the water storage chamber 22. By adopting the water-saving ship lock of the present application, almost zero water consumption can be achieved, thereby greatly reducing the water resource consumption caused by the ship lock when the ship passes.
