Application method

Filling water into a water storage tank 6, closing all valves, enabling a vertical gravity suction head 1 to be underwater, opening a water adding valve 4 and an air outlet valve 5, starting to fill water into a siphon pipe, forming a closed space by the whole siphon pipeline and the water storage tank 6 after water enters a siphon starting valve 9, enabling the end of a power generating pipe 8 to enter a little water, increasing the water level a little, enabling the end of the vertical gravity suction head 1 to enter a little water, increasing the water level a little because the pressure of the closed space is the same and the water level is the same, when the water level at the outlet end of the power generating pipe 8 reaches a certain height, enabling the water at the inlet end of the vertical gravity suction head 1 to start to flow towards the outlet end of the power generating pipe 8 under the action of a difference, closing the water adding valve 4 and the air outlet valve 5, observing that the water flow of a siphon starting valve 9 is gradually increased, gradually increasing the flow of the siphon starting valve to one side from the bottom of the original power generating pipe 8 along with the increase, the siphon pipeline is formally started, once the end of the vertical gravity suction head 1 is blocked and water cannot flow or the water quantity is reduced, the siphon starting valve 9 can be automatically closed or the opening degree is reduced, and the siphon starting valve 9 at the moment becomes a siphon protection valve. The siphon pipeline is avoided being inhaled the head end because of vertical gravity and is blockked up the phenomenon that leads to power to take place the pipe end and admit air and take place just also, because the device is whole inhaling husky in-process, the flow is unfixed at any time and is changing, and it is also frequent to block up and block, just because there is the siphon protection valve, just makes unpowered inhale husky device inhale husky in-process at whole, keeps the siphon throughout not destroyed, inhales husky and can continuous normal operating.

The operation method comprises the following steps:

1. when all valves of the device are determined to be in a closed state, opening an air outlet valve on the water storage tank and a water adding valve with a valve, starting adding water, and respectively closing the air outlet valve and the water adding valve after the water storage tank is full of water;

2. when water is stored in the reservoir and sand needs to be cleaned, opening a ventilation pipe with a valve and a water inlet pipe with a valve on a siphon pipeline, and beginning to inject water into a siphon elbow;

3. when the outlet end is full of running water, the power generation pipe is started, and simultaneously the siphon starting valve is automatically opened, the air exchange pipe with the valve and the water inlet pipe with the valve are closed, so that the siphon pipeline enters a normal discharge use state, and the distance between the section of the gravity vertical suction head at the inlet and the bottom is carefully adjusted;

4. when the flow needs to be reduced or closed, opening an emptying valve or an emptying valve at an entrance of an operation site, observing the flow change, and closing the emptying valve when the flow is proper;

5. when the device is not needed to be used within a period of time, all the valves are opened, all the stored water is discharged, and then the device is closed and reused next time.

The working process is as follows:

when a water reservoir is used for a long time, more and more sediment is deposited, and the water reservoir needs to be cleaned, the mounted unpowered sand suction device is opened, an air outlet valve and a water adding valve on the top of a water storage tank of the unpowered sand suction device are opened, water is added, after the water reservoir is full of water, the air outlet valve and the water adding valve are respectively closed, an air exchange valve and a water inlet valve are opened, water is added into a siphon pipe, before the water is added, whether two emptying valves on a siphon pipeline are closed or not is checked, whether a vertical gravity suction head is placed in the water or not is noticed, a certain distance is required between the vertical gravity suction head and the bottom, whether a siphon starting valve is flexibly used or not is noticed, whether the siphon starting valve is in an automatic closing state, namely whether the siphon starting valve is arranged at the bottom end of a power generation pipe or not is noticed to observe the change of water flow, when the outlet end is full of water, closing the ventilation valve and the water inlet valve, starting the siphon pipeline, enabling the whole unpowered sand suction device to be in a formal operation state, needing a floating boat which can be installed in a split mode on site to be matched with a group of pulley ropes in the sand suction process, paying attention to the fact that the verticality of the vertical gravity suction head is adjusted and maintained at any time, enabling the vertical gravity suction head to be in a 0-5mm away from the bottom surface when meeting a place where the sand is firmly hardened, enabling the vertical gravity suction head to move up and down to collide with a bottom sand layer, enabling a general settled layer to comprise various stones and the like to be sucked out quickly by means of the strong suction force of the device and the gravity collision of the vertical gravity suction head, enabling the sand layer to be punched into a hole, observing the sand suction state by using a diving mask at the vertical gravity suction head, then moving left and right, sucking. The discharged water flows out directly, if the discharged water does not flow, a low-power high-flow pump can be additionally arranged to directly pump the discharged water into a water reservoir for reuse, when the flow of the device needs to be reduced, a field emptying valve can be opened at any time, the change condition of the outlet flow can be observed by using a field visual lens, the adjustment is noticed, if the device needs to be closed and does not need to be used within a period of time, all valves are opened, all stored water is discharged, and the device can be reused next time after being closed.

The length, the pipe diameter and the number of the polyurethane thermal insulation pipe, the metal hose, the siphon pipe and the like can be determined according to requirements, and the vertical gravity suction head can be moved to any underwater position for working, so that the waste of water resources caused by sand cleaning and overhaul of a reservoir can be reduced. The device is suitable for dredging and sand discharging in various places with reservoir potential difference conditions and artificial potential difference conditions, such as suction of silt, stones and sunken ship materials on offshore or underwater construction sites, treatment of liquid or sewage with particle impurities needing to be discharged under potential difference conditions or artificial potential difference conditions in various industries, and discharge and remote conveying of liquid in a high-level storage tank and a storage tank.

Finally, it should be noted that: although the present invention has been described in detail with reference to the foregoing embodiments, it will be apparent to those skilled in the art that modifications may be made to the embodiments or portions thereof without departing from the spirit and scope of the invention.
