From the world, the electricity consumption of developed countries is slowly increased from 1990, gradually approaches or is saturated, and particularly after 2000 years, the economic development level tends to be stable, the increase speed of the electricity consumption is slower, and even the electricity consumption of some developed countries is reduced.
Therefore, the power demand of a country cannot keep increasing situation all the time, the power demand can be saturated or even reduced, and therefore the power grid serving as an electric energy carrier cannot keep a high-speed development state all the time, and the development of the power grid gradually tends to be saturated along with the tendency of the social and economic development to be stable and the basic perfection of the power grid infrastructure.

The distance between the axes of the two wire clamping wheels 3 is fixed, the two wire clamping wheels 3 are both oval, the distance between the outer surfaces of the two wire clamping wheels 3 can be changed in real time due to the fact that the oval has a long axis and a short axis, and if the minimum distance between the two wire clamping wheels 3 is smaller than the diameter of the brake sleeve 5, the two wire clamping wheels 3 can gradually squeeze the brake sleeve 5 on a wire in the rotating process. With the pressing of the brake sleeve 5 by the wire clamping wheel 3, the wire is limited at a specific position through the brake sleeve 5.
In practical application, the relative positions and the spatial angles of the two wire clamping wheels 3 need to be reasonably arranged. The wires in the power grid may have two opposite directions of movement under the action of the external environment, so that the two directions of the brake sleeve 5 need to be limited by the two wire clamping wheels 3.
Here, the oval wire-clamping wheel 3 can be rotated from two directions and becomes the smallest distance, thereby having two-directional limitation to the brake sleeve 5.

In some embodiments of the intelligent take-up device provided by the present application, referring to fig. 1 and 2, two of the capstan wheels 3 are symmetrically distributed.
For convenience of installation and assembly, the two wire clamping wheels 3 need to be symmetrically distributed on two sides of the wire, and after the brake sleeve 5 is sleeved on the wire, the long axes of the two wire clamping wheels 3 are parallel to each other and parallel to the length direction of the wire, so that the movement amplitudes of the wire clamping wheels 3 in two directions are ensured to be the same.
In some embodiments of the intelligent tensioner device provided in the present application, please refer to fig. 2, a limiting block 7 engaged with the slot is disposed on an outer wall of the braking sleeve 5; the limiting block 7 is used for enabling the wire clamping wheel 3 to swing within a certain range through meshing transmission with the clamping groove.
For more detailed description, the stopper 7 is provided on the brake sleeve 5, and the stopper 7 is integrally formed on the brake sleeve 5. Two limiting blocks 7 on the braking sleeve 5 are respectively meshed with two clamping grooves on the two clamping wire wheels 3.
When the lead drives the brake sleeve 5 to move, the limiting block 7 on the brake sleeve 5 can be always engaged with the clamping groove. Because the wire clamping wheel is always in a meshed state, the limiting block 7 can drive the wire clamping wheel 3 to swing within a certain range. And the wire clamping wheel 3 is oval, so that the distance between the two wire clamping wheels 3 can be changed under the driving of the brake sleeve 5.
When the limiting block 7 drives the wire clamping wheels 3 to move to the limiting position, the two wire clamping wheels 3 can extrude the brake sleeve 5, and the stronger the movement trend of the brake sleeve 5 is, the larger the acting force of the wire clamping wheels 3 on the brake sleeve 5 is. At this time, the brake sleeve 5 presses the wire, so that the maximum static friction force between the brake sleeve 5 and the wire is increased, and finally the wire is prevented from slipping.
In some embodiments of the intelligent wire tightening device provided by the present application, please refer to fig. 2, both ends of the brake sleeve 5 are provided with the cut-off blocks 6, the two cut-off blocks 6 are distributed on both sides of the two wire clamping wheels 3, and the thickness of the cut-off block 6 is greater than the maximum distance between the two wire clamping wheels 3.
The brake sleeve 5 can be directly sleeved on the lead, and the extrusion force of the brake sleeve 5 on the lead can be effectively ensured by screwing the bolt and other members on the brake sleeve 5, so that a series of problems of looseness and the like between the brake sleeve 5 and the lead can be avoided.
Firstly, the structure of the wire clamping wheel 3 is determined, the distance between the axes of the two wire clamping wheels 3 is fixed, in order to further limit the limit position of a conducting wire, the two ends of the rotating sleeve are respectively provided with a stopping block 6, and the thickness of each stopping block 6 is larger than the maximum distance between the two wire clamping wheels 3. Even if the limiting block 7 slips off from the clamping groove, the stopping block 6 cannot penetrate through the two wire clamping wheels 3, so that the slipping of the wire is avoided to a certain extent.

After the two brake sleeves 5 are sleeved on the lead through the bolts, the lead can be tightly held, and a larger acting force is generated between the brake sleeves 5 and the lead, so that the problems of dislocation or slippage and the like between the brake sleeves 5 and the lead are avoided.
In practical application, firstly two paying-off wheels 2 pay off wires, after the paying-off wheels 2 pay off the wires to a specified position, a brake sleeve 5 is sleeved on the wires, and the wires are located between the two wire clamping wheels 3. In order to facilitate operation, the conducting wire can be tilted from the space between the two wire clamping wheels 3, and the brake sleeve 5 is respectively clamped and matched with the two wire clamping wheels 3 after the brake sleeve 5 is installed.

The motor is connected with a control switch in a transmission way, and the paying-off wheel 2 rotates forwards or backwards through the control switch.
The cylinder is a cylindrical metal part which guides the piston to do linear reciprocating motion in the cylinder. The working principle of the pneumatic mechanism is that the pressure of compressed air is converted into mechanical energy through pneumatic transmission, so that the mechanism does linear reciprocating motion or swinging and rotating motion. The air cylinders can be divided into four types, namely single-acting air cylinders, double-acting air cylinders, diaphragm type air cylinders and impact air cylinders.
