Description

Scheme for wired power transmission to mobile equipment in local area

Technical Field

The invention relates to a scheme for wired power transmission to mobile equipment in a local area.

Background

At present, most of mobile equipment such as forklifts, excavators and various agricultural machines use gasoline and diesel oil as energy sources. The disadvantages are that: the air is polluted, the use cost is high, and gasoline and diesel oil are non-renewable valuable strategic materials and can be easily pinched by enemies in a very period.

Although some newly developed mobile devices are powered by batteries, which can reduce pollution and use cost, a group of power batteries has low cost, so that the production cost of the mobile devices is increased. The total cost performance of the mobile equipment is not ideal due to the service life limitation of the power battery.

The invention aims to provide a scheme for supplying power to a local mobile device in a wired mode. The mobile equipment can directly use the power electricity as the energy source.

Disclosure of Invention

The invention is realized by the following steps: the power cord is connected to a connector lug above the local area where the mobile device is operating. The connector lug and the power line are fixed on a plurality of upright posts erected at the edge of the working area or on cables arranged among the upright posts. If the work area is indoors, the connector lug and the power line can also be fixed to the corresponding building component. A sleeving electric rod assembly is installed on the mobile equipment, and a fixing rod is arranged below the electric rod assembly and fixed with the mobile equipment. A three-phase power plug is arranged on one rotary rod. After the rotating rod is rotatably connected with the fixed rod, the rotating rod can rotate vertically at will. They are internally provided with a set of 4-way conductive slip rings which can transmit three-phase power. One end of the spiral cable is connected with a three-phase power socket with a handle, and the spiral cable is inserted into a three-phase power plug on the rotating rod. The other end is fixedly connected in a connector above the local area. Because the spiral cable has great length and stretches out and draws back, can follow the reliable power transmission of mobile device in the local. Even if the mobile device is turned in a set local area, the spiral cable cannot be twisted due to the action of the rotating rod. Therefore, the mobile equipment can freely work and move in the set local area.

By adopting the technical scheme of the invention, the mobile equipment can use the power electricity as the energy source in the set local area, so that the mobile equipment has no pollution during working, the use cost is low, and precious strategic resources are not required to be consumed. And the production cost of the mobile equipment is greatly reduced, so that the mobile equipment is an invention technical scheme beneficial to the nation and the people.

Fig. 2 is a partial enlargement of the portion X of fig. 1.

Fig. 3 is a perspective view of the solution of the invention when using the mobile upright in a temporary work area.

Fig. 4 is a perspective view of an embodiment of the present invention.

Referring to figures 1 and 2: 2 upright posts (3) are fixed at the edge of the working area (5), and the upper ends of the upright posts (3) are connected with a cable (1). After the power line (2) is connected with the connector lug (6), a plurality of restraining rings (4) are fixed on the mooring rope (1). A fixed rod (9-3) is arranged below the power connection rod assembly (9) and is fixed with the mobile equipment (10). A three-phase power plug (9-1) is arranged on the rotating rod (9-2) above. After the rotating rod (9-2) is rotationally connected with the fixed rod (9-3), the rotating rod can rotate vertically at will. They are internally provided with a set of 4-way conductive slip rings which can transmit three-phase power. Their mutual structure is solved by common techniques and therefore not described in detail here. The spiral cable (7) is a three-phase cable processed into a spiral shape, one end of the spiral cable is connected and fixed in the connector lug (6), the other end of the spiral cable is connected and fixed with a three-phase power socket (8) with a handle, and power electricity can be conveyed to the mobile equipment after the power plug (9-1) is inserted. The three-phase power socket (8) with the handle can also be provided with a movable lock catch, and can be locked after being inserted into a power plug (9-1). The structure of the connector lug (6) can not only connect and electrify the power line (2) and the spiral cable (7), but also fix and bear the weight of the spiral cable (7), and the common technology can solve the problem. By the scheme, the mobile equipment (10) can freely work and move in a set local area by taking power electricity as an energy source.

Referring to FIG. 3: a movable upright post (11) is arranged at the edge of a temporary working area (12), a plurality of steel pipes (11-1) are welded on a base (11-2), 4 universal wheels (11-3) with brakes are arranged below the base, and the universal wheels (11-3) are in a braking state after rolling to the edge of the temporary working area (12). After the power line (2) and the connector lug (6) are fixed on the movable upright post (11), power can be transmitted to the mobile equipment (10) through the spiral cable (7). The steel pipes (11-1) can also be made into telescopic type so as to reduce the volume when in transportation. This structure can be solved by the ordinary technique.

Detailed Description

The present invention will be described in further detail with reference to examples.

Referring to fig. 4: this is an example in agricultural land. Because the set working area (13) is relatively large, 4 columns (3) are fixed at 4 angles of the area, and one column (3) is also fixed at the center. Is equal to dividing the work area (13) into A, B, C, D4 small areas. Each small area is provided with a set of power line (2), a connector lug (6), a spiral cable (7) and a three-phase power socket (8) with a handle. A sleeving electric pole assembly (9) is also arranged on the mobile equipment B (12) (agricultural machine). Assuming that the mobile equipment B (12) works in the A cell area, after the work is finished, the mobile equipment B (12) is moved to the side of the central upright post (3), the spiral cable (7) of the A cell and the three-phase power socket (8) with the handle are pulled out to be hung on the central upright post (3), and the spiral cable (7) and the three-phase power socket (8) with the handle which are originally hung on the central upright post (3) of the B cell or the C cell are plugged, so that the mobile equipment B (12) can be moved to the B cell or the C cell to work. The same can be done for a large area of work area. The power line (2), the connector lug (6), the spiral cable (7) and the three-phase power socket (8) with the handle are arranged on two adjacent work area sides.
