Detailed ways

The present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

A power supply method for gate hoists in remote areas, as shown in Figure 1. In this method, a set of solar photovoltaic panels 11 and wind turbines 12 are complementary to each other to charge the battery box 8 through the PLC integrated control box 9. The battery box 8 provides DC power for the DC motor through the PLC integrated control box 9, and the DC motor drives the start-up The closing machine 7 completes the opening and closing operation of the gate. The hoist 7 adopts a hoisting structure to connect with the lifting lugs 14 on the gate 3 to control the opening and closing operations of the gate. The hoist or the screw structure is connected with the nut on the gate 14 to control the opening and closing operation of the gate.

The layout structure of gate hoists for remote areas constructed according to the aforementioned method is shown in Figure 1. Including channel 1, there are door slots 2 on both sides of channel 1, and gates 3 are arranged between the door slots 2 on both sides of channel 1; The hoist machine room 6; the hoist machine room 6 is provided with a hoist machine 7, a battery box 8 and a PLC integrated control box 9; a set of solar photovoltaic panels 11 and wind power are installed on the roof platform 10 on the top of the hoist machine room 6 Unit 12. The hoist 7 is installed on the ground of the hoist room 6 just above the gate 3, and there is a hoist operation hole on the ground; the hoist operates the gate 3 through the hoist operation hole.

Example

A water conservancy project has a channel control gate with a width of 3.1m, a height of 2.2m, and a design head of 1.9m. According to the design conditions and field investigation, the control gate is located in a remote location and has inconvenient traffic. The control gate needs a hoist. Smaller capacity and less frequent use. If the existing technology is used to lay a dedicated power supply line, a long transmission line needs to be erected, the transmission line occupies a large area, requires a large investment, a long construction period, and the coordination of various aspects is extremely cumbersome.

Therefore, in this example, the solar photovoltaic panels and wind turbines are complementary to charge the battery pack through the PLC integrated control box. The battery pack provides DC power to the DC motor through the PLC integrated control box, and the DC motor drives the hoist to complete the opening and closing of the gate. Close operation. The hoist adopts the winch structure to connect with the lifting lugs on the gate to control the opening and closing operation of the gate; or the hoist adopts the screw structure to connect with the nut on the gate to control the opening and closing operation of the gate.

In the specific implementation, first, the bent frames 5 are erected on the canal top platforms 4 on both sides of the channel 1, and the hoisting machine room 6 is built on the top of the bent frame 5, and the hoisting machine room 6 directly above the door slot 2 of the channel 1 is constructed. A hoist 7 is arranged on the ground, and the hoist 7 is driven by a DC motor. The hoist 7 of this example adopts a hoisting hoist. The DC motor is powered by the battery box 8, and the battery box 8 is charged by the solar photovoltaic panel 11 and the wind generator set installed on the roof platform on the top surface of the hoist machine room 6 when the hoist is not working. When the hoist 7 needs to be used, the battery box 8 provides power for the DC motor, the DC motor drives the hoist to rotate, and the gate 3 is opened or closed by hanging the lifting lug 14 on the top of the gate 3 through the hook at one end of the hoist wire 13.

In addition to the hoisting hoist shown in FIG. 1 , the present invention can also control the opening or closing of the gate by the transmission mode of the screw and the nut. The hoist drives the screw to rotate, the screw is connected with the nut, and the nut is fixed on the gate. When the screw rotates, the nut cannot rotate with the screw, so the nut can only move up and down along the axis of the screw, and the gate is driven by the nut to open or close.
