The gate is generally used for hydraulic buildings such as overflow dams, bank spillways, water discharge holes and hydraulic tunnels, and has the functions of intercepting water flow, controlling water level, adjusting flow, controlling shipping, discharging silt and floating objects and the like.
In the prior art, the opening and closing of the gate are mainly realized by two modes. The first way is to rely on manual opening and closing of the gate. The opening and closing mode has low efficiency and high labor intensity. The second mode is that the power is supplied by a power grid or a storage battery, and the gate is driven to open and close by a motor. However, in some remote small-scale hydraulic projects, the remote small-scale hydraulic projects are far away from villages and cities, and power stations are not built around the remote small-scale hydraulic projects, so that a power supply source is not provided, and the opening and closing frequency of a gate is low. If a long power transmission line needs to be erected for laying a special power supply line, the investment of the power transmission line is large, the construction period is long, and all aspects are coordinated very complicatedly. If the storage battery is used for supplying power, the problem that the storage battery is easy to age is firstly faced.

The seventh cable 79 should satisfy one of the following conditions:
(a) one end of the seventh inhaul cable 79 is detachably connected with the weight 71, and the other end of the seventh inhaul cable is fixedly connected with the opening and closing rod of the gate;
(b) one end of the seventh inhaul cable 79 is fixedly connected with the weight 71, and the other end of the seventh inhaul cable is detachably connected with the opening and closing rod of the gate;
(c) one end of the seventh cable 79 is detachably connected to the weight 71, and the other end is detachably connected to the open/close lever of the gate.
It should be noted that the density ρ of the weight 71 should be at least greater than the density of water, so as to reduce the space occupied by the open-door water tank 20 and the closed-door water tank 40. Preferably, the weight 71 may be an iron block, a copper block or a concrete block. In a more preferred embodiment, the weight 71 is a concrete block, in view of cost.
The working principle of the gate opening and closing device is briefly explained by taking the connection state of all the inhaul cables as the original state:
when the door is opened, referring to fig. 2, the fourth cable 74 and the seventh cable 79 are disconnected, and the rest cables are connected, so that the linkage between the weight 71 and the gate and the door-opening water tank 20 is cut off. The power water tank 10 fills water into the open water tank 20 to increase the weight of the open water tank 20, and the weight 71 and the open water tank 20 simultaneously draw the gate to open (rise) and the closed water tank 40 to rise, so as to open the gate (refer to the state shown in fig. 3).
Then, the weight 71 is reset, and the specific steps are as follows: referring to fig. 3, the first and second cables 53 and 56 are disconnected; since the gate 100 is subject to the water pressure, the friction between the gate 100 and the gate rail is large. Therefore, even if the weight 71 is not operated, the shutter is not closed (lowered). The water in the open water tank 20 is drained, and the closed water tank 40 is filled with water to lift the weight 71 and the open water tank 20, thereby completing the resetting of the weight 71 (refer to the state shown in fig. 4). Then, the third cable 72 is disconnected, water in the water tank 40 is drained, water is filled into the open water tank 20, the water tank 40 is pulled to rise by the fifth cable 76, and the reset of the water tank 40 is completed (refer to the state shown in fig. 5).
When the door is closed, referring to fig. 5, the first cable 53, the second cable 56, the fourth cable 74 and the seventh cable 79 are connected, and the weight 71 and the door closing water tank 40 simultaneously draw the closing (descending) of the shutter and the ascending of the door opening water tank 20, thereby closing the shutter 100 (refer to the state shown in fig. 6).
Then, the weight 71 is reset again, and the specific steps are as follows: referring to fig. 7, the first, second and seventh cables 53, 56 and 79 are disconnected, water in the water tank 40 is drained, the water tank 20 is filled with water, and the weight 71 and the water tank 40 are lifted by the fourth and fifth cables 74 and 79, thereby completing the resetting of the weight 71. Subsequently, the fourth pulling cable 74 is disconnected, water in the open-door water tank 20 is drained, water is filled in the closed-door water tank 40, the open-door water tank 20 is lifted through the fifth pulling cable 76, and the open-door water tank 20 is reset.
The operation is repeated to realize the opening and closing of the gate.
It should be noted that, since the solar pumping system continuously pumps the water in the storage tank 30 to the power water tank 10, the power water tank 10 has enough water, and is generally full.
In the above neutralization, the connection between the first cable and the second cable is not the connection between the first cable and the second cable. For example, in the above description, the "connecting the first cable 53, the second cable 56, the fourth cable 74, and the seventh cable 79" means: the two ends of the first pull rope 53 are respectively connected with the opening and closing rod of the opening water tank 20 and the gate; two ends of a second inhaul cable 56 are respectively connected with the door closing water tank 40 and the opening and closing rod of the gate; a first pull cable 53 or an opening/closing lever for connecting both ends of the fourth pull cable 74 to the weight 71 and the gate; both ends of the seventh cable 79 are connected to the weight 71 and the opening/closing lever of the gate, respectively.
The weight of the closed water tank 40 at the maximum water filling amount is heavier than the weight 71.
In the above, the overflow pipe 60, the vent pipe 70, the open inlet pipe 21, the closed outlet pipe 42, the open outlet pipe 22, the pumping pipe, and the closed inlet pipe 41 may be hoses, such as rubber pipes or plastic pipes. Wherein, the overflow pipe 60 and the pumping pipe can also be hard pipes, such as steel pipes.

discharging water in the door opening water tank 20, and filling water into the door closing water tank 40 to increase the weight of the door closing water tank 40, so that the gate is dragged to descend and the door opening water tank 20 ascends to close the gate;
a step of pumping water, namely pumping water,
and pumping the water in the water storage tank 30 into the power water tank 10 by using a solar water pumping system.
Through the technical scheme, the opening and closing of the gate can be realized.
