The technical scheme is as follows: in order to solve the technical problem, the invention provides a shore power transmission line floater, which is an intermediate auxiliary device for transmitting a cable to engineering equipment, wherein the distance and the used specification of each floater are set according to the distance from the engineering equipment to a shore mobile power supply and the external environment when each floater is used.

The utility model provides a bank electricity biography line float ware is connected in the preloading device of electric wire, the preloading device below is equipped with detachable locking movable switch, the pretension is fixed and is located the upper end of activity grillage, can be at any time according to the angle of the concrete reality of the surface of water at that time and the specification adjustment activity grillage of power transmission line, guarantees from this that the float ware is applied to the balance and the stability of transmission electric wire.

According to the integral planning design of the shore power transmission line floater, the floater adopts an inwards concave type movable design, and the movable plate frame can be rotatably recycled into the groove at the end, so that the floater is beneficial to storage, is beneficial to stacking of the floater devices one by one, and is beneficial to convenient transportation.

A bank electricity biography line float ware is equipped with balanced string post, and balanced string post is used for keeping the stability of float ware and preventing that two float wares from taking place the motion in opposite directions. The balance mounting column is used for mounting an anchorage device or a heavy object, and when side force occurs, unnecessary side force can be effectively balanced to ensure that the electric wire does not fall into water.

Furthermore, a bank electricity biography line float ware is equipped with detachable pneumatic valve. The air valve is selected completely according to the specification of the power transmission line and the specific hydrological condition, so that the proper air valve ensures sufficient buoyancy to adapt to the actual condition.

Has the advantages that: the shore power transmission line floater is convenient to transport and carry, economical and practical, and optimizes the balance of the floater during transmission, so that the effect of better adapting to different actual working conditions can be achieved.

Drawings

Fig. 1 is a main schematic view of the structure of the invention, and fig. 2 is a schematic view of a transmission cable of the floater.

The specific implementation mode is as follows: the present invention will be further described with reference to the accompanying drawings.

As shown in fig. 1, the shore power transmission line floater comprises an air valve 1 connected to the lower end of the floater, a movable plate frame switch button 2, a balance hanging column 3, a movable plate frame 4, an elastic adjustment button 5, an elastic adjustment device 6, a pre-tightening device 7, a detachable locking movable switch 8 and an auxiliary support frame 9; the movable plate frame 4 is connected with the floater through a movable shaft, and the auxiliary support frame 9 is connected with the movable plate frame 4 through a fixed shaft; the method comprises the following specific use steps of connecting a floater with an air valve 1, after the operation is finished, pressing a movable plate frame switch button 2 to enable a movable plate frame 4 to rotate out of an inner groove around a movable shaft, further adjusting a proper angle, rotating an auxiliary support frame 9 by a certain angle through a fixed rotating shaft, inserting the far end of the auxiliary support frame 9 into the inner groove, forming a stable triangular structure to achieve the effect of balancing acting force, then detaching the upper half part of a lower pre-tightening device 7 through a detachable locking movable switch 8, smoothly placing a power transmission line on the lower half part of the pre-tightening device 7, pre-locking the power transmission line through the detachable locking movable switch 8, further locking the power transmission line through a tightness adjusting device 6 to prevent the power transmission line from moving in the horizontal direction, adjusting the vertical displacement of a locking blade inside the pre-locking device through the tightness adjusting button 5 to achieve the further locking effect, in order to prevent the two floaters from moving oppositely under the uncertain condition, so that the power transmission line inevitably falls into water, a certain weight or anchorage device can be hung on the balance hanging column 3, the effect of fixing the positions of the floaters can be achieved, the floaters cannot move transversely and longitudinally, the balance of the buoyancy system can be further guaranteed, the lateral force caused by bearing the power transmission line can be offset, and the actual hydrology and the working condition can be better adapted through the method.
