DETAILED DESCRIPTION OF THE EMBODIMENTS

[0014] The following will clearly and completely describe the technical solutions in the embodiments of the present utility model with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments.

[0015] Embodiment 1

[0016] As Figures 1 to 3 shown, a specific embodiment of a hydraulic station for a city flood - control water gate according to the present utility model includes: an oil tank 1 for storing hydraulic medium, on which a common gear pump 2 and a standby gear pump 3 are installed. Both the common gear pump 2 and the standby gear pump 3 are connected to the main valve block 5 through pipelines. On the main valve block 5, a stacked overflow valve 11 and a stacked valve group are installed. The stacked valve group is connected to the water gate cylinder 6 to control the opening and closing of the water gate. The stacked valve group includes a stacked double - one - way throttle valve 12, a hydraulic lock 13, and an electromagnetic directional valve 14. A return - oil filter 7 is also installed on the oil tank 1, and the return - oil filter 7 is arranged at the oil return end of the hydraulic station. Among them, the stacked valve group and the water gate cylinder 6 are correspondingly arranged in three groups, and this hydraulic station can realize the control of three groups of water gate cylinders 6.

[0017] A manual pump 4 is also installed on the fuel tank 1. The manual pump 4 is connected to the main valve block 5. When the electric pump fails, emergency operation can be carried out through the manual pump to ensure the normal opening and closing of the water gate.

[0018] A liquid level temperature sensor 8, an air filter 9, and a liquid level thermometer 10 are also installed on the fuel tank 1. The liquid level temperature sensor 8 is used to monitor the oil temperature and liquid level changes, and the air filter 9 is used to prevent impurities in the external air from entering the fuel tank 1.

[0019] The working principle of the present utility model: The present utility model provides power for the system through the common gear pump 2 and the standby gear pump 3 in the fuel tank 1. When it is necessary to control the opening and closing of the water gate, the motor drives the gear pump to suck hydraulic oil from the fuel tank 1, and after pressurization, it passes through the main valve block 5 and the stacking valve group, that is, the stacked double one-way throttle valve 12, the hydraulic lock 13, and the electromagnetic directional valve 14, to precisely control the flow direction and pressure of the hydraulic oil, thereby driving the water gate cylinder 6 to open or close the gate; when the common gear pump 2 fails, the standby gear pump 3 starts quickly to ensure the normal control of the water gate, enhancing the emergency response ability and reliability of the system; the oil return filter 7 on the fuel tank 1 is responsible for filtering impurities in the oil return, keeping the oil clean, and extending the service life of the system; at the same time, the liquid level temperature sensor 8 monitors the oil state in real time to ensure the safe operation of the system; in special cases, the manual pump 4 can be used as an emergency power source to maintain the operation of the hydraulic system through manual operation.
