Description
Technical field
It is related to power domain, and in particular to temperature becomes expansion bend, power equipment, power grid installation, network system.
Technical background
Expanding with heat and contract with cold for power circuit leads to problem the more, for example summer electric wire expanded by heating leads to the parallel floor portion of electric wire
The terrain clearance divided reduces, and for another example winter electric wire may cause the reduction of electric wire service life by cold events or break, all danger close.
Summary of the invention
The present invention relates to temperature to become expansion bend, power equipment, power grid installation, network system, and preventing from expanding with heat and contract with cold causes
The terrain clearance of parallel above ground portion reduces, and provides new design philosophy, has following technology contents.
Technology contents 1, temperature become expansion bend, it is characterised in that: including fixed plate, movable pulley, movable pulley rack, fixed pulley, determine
Pulley yoke, contract cylinder, slide bar, the drawstring of rising；
Fixed plate is indefinite with respect to ground fixation, has guide hole in fixed plate；
The quantity of movable pulley is at least two, and movable pulley fixed array is in the spacing in movable pulley rack, between each movable pulley
Greater than twice of the diameter of movable pulley；
The quantity of fixed pulley is at least two, and fixed pulley fixed array is in the spacing on fixed pulley frame, between each fixed pulley
Greater than twice of the diameter of fixed pulley；
Fixed pulley frame opposing fixed plate is fixed；
Slide bar is fixedly linked with movable pulley rack；
Slide bar can slide in the guide hole of fixed plate along the axis of the guide hole of fixed plate, drive movable pulley rack along solid with this
The axial-movement of the guide hole of fixed board, and then drive movable pulley movement；
Drawstring is alternate round-trip to be through between movable pulley and fixed pulley, when movable pulley movement between movable pulley and fixed pulley
The non-free length of occupied drawstring is equal to the product of pulling rope length and the round-trip number of drawstring between movable pulley and fixed pulley；
The rise piston of cylinder of contracting is fixedly linked with movable pulley rack, and the rise cylinder body of cylinder of contracting is fixedly linked with fixed pulley frame；
Contracting rise cylinder cylinder body in there is fluid, for fluid in expanding with heat and contract with cold attribute, the substance of fluid excludes water.
2, further: insulated connecting piece is made of ceramics.
3, further: drawstring is made of insulation, hydrophobic material.
4, further: the tail end of drawstring is connected with pouring weight, and the head end of drawstring is connected with pulling force cable, and pouring weight is placed on ground
On face or platform, when gravity of the pulling force of cable greater than pouring weight, by pulling force cable pull-up, pulling force suffered by pulling force cable is up to pouring weight
The weight of pouring weight can prevent temperature from becoming the excessive bad pulling force cable of drawing of power of expansion bend.
5, power equipment becomes expansion bend with temperature described in 1.
6, power grid installation becomes expansion bend with temperature described in 1.
7, network system becomes expansion bend with temperature described in 1.
Technology contents explanation and its advantages.
The present invention is to solve height and pulling force caused by pulling force cable expands with heat and contract with cold with the characteristic of fluid expanded with heat and contract with cold to ask
Topic adjusts required energy from temperature change, is not necessarily to other energy sources.Fluid can select inert gas, alcohol, nitrogen
Gas, carbon dioxide gas, filtered air etc., but water is excluded, because water is that can expand, and zero degree is the mankind in zero degree
The common temperature in residential area winter pulls cable in order to which water expands externally force, excludes water.
The configuration of the present invention is simple, low in cost, long service life, it is easy to accomplish, easy to use, be not necessarily to the energy, Ke Yishi
The constant height of existing cable, tensions constant.
Detailed description of the invention
Fig. 1 is the schematic diagram of the embodiment 1 of invention, and pulling force cable is not in contact with power cable in figure.
Wherein M is the direction of motion of slide bar；In order to know figure conveniently, the section of the first angle pulley, second is presented in figure
The image of A-A.It is convenient in order to know figure, expansion bend is become to temperature using dotted portion and is divided.
Specific embodiment
Embodiment 1, the cable trough with pulling force cable become expansion bend, buffer spring, insulation including temperature described in summary of the invention
Connector, angle pulley, pulling force cable, power cable, seton device；
Reversing gear bracket is mounted on the top of electric pole, reversing gear bracket has fixing axle；
Angle pulley is positioned on fixing axle；
Angle pulley can be rotated around fixing axle；
Direction of routing is perpendicular to ground after pulling force cable passes through angle pulley；
Pulling force cable tangles power cable via seton device；
The head end for the drawstring that the lower end of insulated connecting piece SC1 becomes expansion bend with temperature via buffer spring is fixedly linked；
When temperature heating, temperature becomes expansion bend and pulls down insulated connecting piece, straightens pulling force cable, makes the aerial part of pulling force cable not
It can sink because of heat expansion, while improve the height of power cable, when temperature turns cold, temperature becomes expansion bend and loosens drawstring, prevents from drawing
Power cable deforms due to the pulling force for shrinkage or service life reduction.
Further: seton device is insulation.
Further: buffer spring surface has insulating materials.
Embodiment 2 removes buffer spring, and the head end for making temperature become expansion bend is directly connected with the bottom end of insulated connecting piece.
Embodiment 1 is used for power equipment by embodiment 3.
Embodiment 1 is used for power grid installation by embodiment 4.
Embodiment 1 is used for network system by embodiment 5.
