[0033] The electro-hydraulic yoke driving mechanism 4 is arranged in the valve well 1, and the electro-hydraulic yoke driving mechanism 4 is used for controlling the opening and closing of the pipeline valve 3 on the raw water pipeline 2.

[0034] The control unit 10 is arranged on the support rod 9, the support rod 9 is arranged on the ground, and the control unit 10 is electrically connected with the electro-hydraulic yoke driving mechanism 4 through the control cable 5.

[0035] The electro-hydraulic shift fork drive mechanism 4 is conventional technology. For example, it has an IP68 protection rating and comprises an 80,000 Nm torque hydraulic cylinder, a valve stop box, an accumulator, a 50L low-pressure oil tank, a 250W hydraulic pump, and a 24VDC solenoid valve. Before the control unit 10 issues an instruction to open or close the pipeline valve 3, the hydraulic pump operates, pumping hydraulic oil from the tank into the accumulator. To open or close the pipeline valve, the solenoid valve activates accordingly, and the flow of hydraulic oil activates the drive mechanism, which in turn activates the pipeline valve, thereby opening and closing the pipeline valve 3.

[0036] Photovoltaic panels 7 are arranged on support poles 9. Photovoltaic panels 7 are used to convert solar energy into electrical energy.

[0037] The battery pack 8 is arranged on the support rod 9, and the battery pack 8 is electrically connected to the photovoltaic panel 7. The photovoltaic panel 7 and the battery pack 8 are both existing technologies. For example, the photovoltaic panel 7 includes two 500W photovoltaic panels, outputs 24VDC, and the battery pack 8 is a battery pack with a capacity of 400AH. The photovoltaic panel 7 is used to charge the battery pack 8. In order to prevent overcharging and reverse charging from damaging the battery, it can be equipped with a solar controller for management and protection. The battery pack 8 is used to power the control unit 10 and the electro-hydraulic fork drive mechanism 4. Since the electric power required by the electro-hydraulic fork drive mechanism 4 is relatively small, the power demand can be met by the battery pack 8 and the photovoltaic panel 7 without the need for an external power supply, which meets the long-term safety and reliability requirements of the valve well control system.

[0038] A rain shield 12 is provided on the support rod 9. The rain shield 12 may be an umbrella-shaped structure, such as an umbrella, etc. The rain shield 12 can serve to protect against rain.

[0039] Based on the above structure, the valve control system provided in this embodiment controls the opening and closing of the pipeline valve 3 through the electro-hydraulic fork drive mechanism 4, which greatly saves manpower for opening and closing the valve and shortens the time for opening and closing the valve. The control unit 10 is set on the ground, so that subsequent operations and maintenance can be carried out on the ground, reducing the danger of working in underground confined spaces. The electro-hydraulic fork drive mechanism 4 and the control unit 10 are powered by photovoltaic panels 7 and battery packs 8, avoiding the need to introduce power from the outside and reducing wiring costs. The rain shield 12 can provide rain protection, preventing long-term erosion by rainwater, and extending the service life of the equipment.

[0040] The valve control system provided in this embodiment further includes a cable casing 6, which is pre-buried under the ground and through which the control cable 5 passes. The cable casing 6 can protect the control cable 5 and prevent it from being damaged.

[0041] The valve control system provided by the embodiment further comprises a camera 11 arranged on the support rod 9. The camera 11 can be electrically connected to the control unit 10. The camera 11 can monitor the surrounding situation in real time and transmit signals to the control unit 10.

[0042] The control unit 10 can comprise a 4G communication module. Through the 4G communication module, signals can be transmitted to a superior control center, and instructions from the superior control center can be received. For example, the system state can be monitored, the valve can be controlled on site or remotely, and signals such as valve opening to position, valve closing to position, opening, closing, low oil level alarm, motor operation timeout alarm, accumulator pressure sensor, voltage fault alarm, low battery level alarm, battery level sensor, protection box door opening alarm, local / remote state, etc. can be collected and uploaded.

The flow guide slope can be parallel to the photovoltaic panel 7, and the bottom end of the flow guide slope is connected to the top end of the photovoltaic panel 7. In this way, the rainwater collected in the rain shield 12 can flow along the flow guide slope to the photovoltaic panel 7, increasing the scouring effect of the rainwater on the surface of the photovoltaic panel 7, avoiding excessive dust accumulation on the photovoltaic panel 7, and prolonging the service life of the equipment.

[0046] The battery pack 8, the control unit 10, and the camera 11 are located below the rain shield 12. In this way, the rainwater can be prevented from scouring the battery pack 8, the control unit 10, and the camera 11, thereby prolonging the service life of the equipment. At the same time, the rain shield 12 should avoid blocking the photovoltaic panel 7 to affect the working efficiency of the photovoltaic panel 7.
