Referring to Fig. 3-1, Fig. 3-2, B phase travel wheel 7 structures are: left side plate washer 7a and circular right side plate washer 7b by circle connect to form through bolt 7d, be fixed with one on the right flank of left side plate washer 7a as the fixing inner core 7e of power transmission shaft 4 insertions, the trip bolt hole is arranged on the inner core 7e, be fixed with a rolling tube 7c on the left surface of right side plate washer, the overall diameter of the tube that rolls is less than the overall diameter of left and right side plate washer.
The unit of advancing:
As seen from Figure 2: the travel wheel of A, B, C three-phase is installed on the power transmission shaft, under the rotation of the motor of advancing, drives (16 tooth) driving gear, promote (8 tooth) driven gear again, speedup is 2 times thus, and and then drive power transmission shaft, A, B, C three-phase travel wheel are rotated.
With the power line cable is track, then will form the winch formula structure of outer high inner cylinder.So on power transmission line, both can roll, can stop derailing again.
Travel wheel must closely interlock with power transmission shaft, just drive can be arranged, and therefore, adopts trip bolt that power transmission shaft is fixed on inner core.
Left side plate washer and inner core preferably adopt founding technology to be made into integral body among Fig. 3-2.
When power transmission shaft after the left side plate washer fixes, again the left and right side plate washer is merged, adopt screw rod to connect, form complete travel wheel.
Travel wheel speed and platform number calculate:
What this device was selected is the servomotor that direct current 24V, per minute 60 change, just in time turned around in 1 second, by calculating as seen:
Girth=10 * 3.14 ÷ 100=0.314 m;
Through 2 times of change pulley speedups, then a hour driving range is:
0.314×2×60×60÷1000＝2.26?km；
In every covering device darg 6 hours, last 100 kilometers icing circuits, need:
100 ÷ (6 * 2.26)=7;
Even construct simultaneously with these 7,8 table apparatus, 100 kilometers icing circuit just can be abolished in 5,6 hours.
By dish (being the left and right side plate washer) about above respectively as seen with one mode and calculated data, it is fastening but also solved the problem that rolling speed improves that this travel wheel had not only solved power transmission shaft, and assembling process can not disturb obstruction mutually, so be not only to have improved but also design cleverly.
Though the three-phase travel wheel can adopt split-phase motor to drive in addition, even if but choose the same model motor in the real work, the difference that also can have startup, rotating speed and even control device conversion speed, these differences are utilizing power transmission line to do track, in the extremely limited running status of cross section, be easy to occur imbalance, distortion even derailment occurring.So we have done the three-phase travel wheel is fused through power transmission shaft, by a driven by motor, synchronize them the design of running, unique and effective has solved the problems referred to above.
The assurance of phase spacing and adjustment:
In 10～500kV power transmission line, consider that line weighs down the influence in many ways of radian and wind throw, for preventing the butt joint discharge, all design aerial phase spacing a lot greatly than GB by experience, generally at several meters in tens meters.The 220kV power transmission line of deicing emphasis circuit for example generally is taken as 7 meters from the phase spacing of iron tower output, because the market bonding jumper is generally 6 meters long, has any problem so purchase 7 meters whole.
For this reason, we have adopted the conduit connection to add regular way, and among Fig. 8, two 3 meters bonding jumpers of joint (as power transmission shaft) are connected through 2 meters lengthening sleeve pipes, and the bottom also is provided with the feet that is fixed in base plate, and the pin rim of a cup is wiped with lubricated butter.The existing like this assurance of the required 7 meters length of 220kV again can be because of the long tenesmus of metalwork.
In conjunction with changing propeller shaft length, also can do the adjustment of other voltage level phase spacing.
Transmission line has GB, the experience data are arranged, also has varying of topography and geomorphology, so, introduce the design of conduit in this device, but both coarse adjustment, but fine tuning has again made things convenient for on-the-spot use greatly, is the good treatment method.
Certainly, 7 meters metalworks are long and constant weight are arranged, and for preventing tenesmus, have added a circular arc bearing, stamp butter, promptly play a supporting role, and do not influence the spinfunction of power transmission shaft again.
The deicing unit:
Peening hammer in Fig. 2, (double pendulum) direct current machine, swing arm slotted eye constitute deicing unit (referring to Fig. 4).When motor obtains work order, promptly to do 180 ° and come and go and rotate, last underarm overturns thereupon, resembles mechanical hand drive peening hammer and impacts icing on the power transmission line from the above and below, and these ice sheets will be reached the deicing purpose by one shoots down.
Among Fig. 4, peening hammer and common hammer are different, and we design and produce it and are arc shape, will form circumference encirclement shape up and down for being commonly circular cable like this, and it is bigger to make it contact-making surface, and better effects if opens ice.
Brake unit:
Because of power transmission line has deadweight, condensing of ice sheet will make the cable tenesmus in addition, and the also formation great slope that has often needs observation, adjustment etc. so hit in the ice.For preventing that stagnating fashionable dress deposits cunning, therefore designed the braking system that support spring and brake block and set bolt etc. constitute by brake solenoid.Fig. 5 amplifies signal, presses down bolt spring and brake block are fixed on the device base plate.Spring is strutted brake block by self-acting power at ordinary times, when electromagnet obtain the instruction, charged adhesive, its wire is left behind brake block, and travel wheel is stopped operating, and reaches the purpose of Brake stop.
Fixed form:
The motor of three-phase deicer, valve formula electromagnet, travel wheel, accumulator jar, wireless receiving and controller etc. all are fixed on a metal or the insulating base, how do they guarantee with the travel wheel sportex, and their motion influences gait of march and increases energy consumption?
Referring to Fig. 2, in the device work, when the driven by motor power transmission shaft rotates, the three-phase travel wheel that is fixed on the power transmission shaft all will be rotated synchronously, advance or will retreat along same direction.
Through last installation, though metal base plate has two fixing points,, even be overlapped on the power transmission line along with operation and vibration might produce and tilt forward and back, like this must resistance, increase energy consumption.For this reason, we B in Fig. 2 has set up two support wheels in front and back mutually, Fig. 7 is the amplification signal of positive apparent direction, as can see from Figure 7: back shaft 18a and close-fitting interior circle clinching (being fixture 19) that fastening bolt will play fixation are fixed on the metallic plate, and back shaft is fixed on the rolling bearing 18b inner ring.
Two spring bearings (containing bearing pedestal) of back and front supporting wheel and B phase power transmission line and arranged on left and right sides four wheels altogether constitute diamond structure, no matter how loading base vibrates, good balanced support effect is all arranged, base plate all is seated on the central shaft of each bearing in addition, so radial height of wheel that lifting is high, so then can not produce friction, cut down the consumption of energy thus yet with lead and ice sheet.
This deicer has bored a series of big apertures in the space of base plate, be beneficial to be crashed to pieces on the power transmission line and splash down ice cube in casing, or directly or change into frozen water and drop out, increase installation weight onboard in order to avoid pile up.
This deicer has also been done the arc case lid, and by totally 4 holes of the case lid connecting hole 23(among Fig. 2) connect, but in practice, for alleviator pressure be convenient to observe each part ruuning situation, often do not use, but process by the modes such as joint of wrapping, good seal motor and control piece, prevent that the frozen water short circuit from getting final product.
But, this case lid then will cover when indoor storing, because of preventing the long-pending foreign object strike etc. of echoing of dust like that.
" mountain " word de-icing of power transmission lines structure:
Referring to Fig. 9-1, we are example with the three-phase equilibrium power transmission line for the front, have done the introduction of synchronous deicing, but also have the equal direct screening of a lot of A, C to connect the iron tower both wings in the scene, and middle B raises mutually, are beneficial to " mountain " font power transmission mode that phase spacing is arranged.For this structure, we then adopt the two synchronous methods that combine shown in Fig. 9-2.Remove driving wheel this moment and motor moves on to a side, and outside AC same plate and AB or BC same plate, other electromechanical structure, control mode, application principle are all the same, so no longer carefully state.
As fully visible, no matter the inclined-plane, plane, no matter the three-phase two-phase, so long as have a power failure, can attachment strap, we advocate to adopt the synchronous deicing of said apparatus, because such one be that two above strong points can be set, can not fall down in advancing; The 2nd, can construct favourable quickening progress simultaneously.
Control device:
After three each device of synchronised deicer are provided with installation, operation on the cable of high-altitude, also have problems such as a series of power supply, distant news, control to need to solve, make introductions all round below.
Working power:
Each motor, electromagnetically operated valve etc. will be worked in the device, must need electric energy.Electric energy can be by as the civil power of Figure 11-a and vapour, diesel generation and behind step-down, rectifying and wave-filtering, from ground supply.Such advantage is that the energy attenuation influence is little, and can reduce the high-altitude and carry the energy storage facility; Shortcoming is to be with long lead plait from ground to the aerospace equipment, influenced by trees and gully, the mountain ridge, will occur hindering, even be difficult to construction.Our emphasis still is designed to the accumulator jar method for this reason.
Figure 10 illustrates, the control circuit structure is: through the 24V dc power anode after the voltage-stabiliser tube voltage stabilizing connect in turn the 1st binding post of described receiver and relay J 1 often open node J1-1 after be connected in motor D X one end of advancing, this power cathode is connected to motor D X one end of advancing after connecting the 2nd binding post of the normally closed node J1-2 of the 3rd binding post of receiver and relay J 1 and receiver in turn; The 24V dc power anode is connected to this power cathode after connecting the 6th binding post of the normally closed node J2-2 of the 5th binding post of often driving node J2-1, the motor D of the advancing X other end, receiver of the 4th terminal, relay J 2 of described receiver and relay J 2 and receiver in turn; The 24V dc power anode be connected in series in turn relay J 5 often open node J5-1, normally closed node J5-2 after be connected to this power cathode, the 24V dc power anode be connected in series in turn relay J 6 often open node J6-1, normally closed node J6-2 after be connected to this power cathode, and one after three direct current machines of described rapping apparatus corresponding to the three phase transmission line cable are in parallel is terminated at the tie point of often opening node J5-1 and normally closed node J5-2, and the other end after the three direct current machine parallel connections is connected to the tie point of often opening node J6-1 and normally closed node J6-2; The 24V dc power anode is series resistor R2 in turn, relay J 3 often open node J3-1, the 8th binding post of receiver, be connected to the collector electrode of triode BG1 after the relay J 5, the emitter of triode BG1 is connected to this power cathode, be connected to the collector electrode of triode BG2 after the 8th binding post serial connection relay J 6 of receiver, the emitter of triode BG2 connects this power cathode, electrochemical capacitor C2 positive pole is connected to the collector electrode of triode BG1, electrochemical capacitor C3 positive pole is connected to the collector electrode of triode BG2, electrochemical capacitor C2 negative pole is connected to the base stage of triode BG2, and electrochemical capacitor C3 negative pole is connected to the base stage of triode BG3.
Also have electromagnet power supply circuit: the 1st binding post of described 24V dc power anode receiver in sequential series, the 4th binding post, the 10th binding post, relay J 4 often open node J4-1 and magnet spool after be connected to this power cathode.
Also have two lower ends of duplex potentiometer W1:W1 and connect described electrochemical capacitor C2 negative pole and electrochemical capacitor C3 negative pole respectively, two upper ends of W1 all are connected (top is the lower end for upper end, below among Figure 10) with receiver the 8th binding post.
Also have the receiver operation power supply: described 24V dc power anode is connected to the 7th terminal of receiver, and this power cathode is connected to the earth terminal of receiver.
Also has the working power indicating circuit: be serially connected with light-emitting diode Fg1 and resistance R 1 between described 24V dc power anode and this power cathode in turn.
The 24V DC power supply composes in parallel after being connected in twos by 4 joint DLM-12 storage batterys again; Perhaps the 24V DC power supply is: to the 220V alternating current handle by transformer, silicon rectifier, the voltage-stabiliser tube circuit formed of cascade in turn.
Among Figure 10, adopt 4 12V accumulator jars in twos series, parallel use, like this, series connection: power supply can meet 12 * 2, i.e. 24V direct current machine need of work, parallel connection: then lay in more multipotency.Thus, for advancing, impact totally four servo direct current motor that gross power is about 160 watts, charging once can move about 20 kilometers, can satisfy one day deicing mileage basically.
Remote controller:
These three a synchronised deicers wherein significant role are to replace electrician's work high above the ground, so possess the remote operation controlled function.And the consideration topography and geomorphology, even the river that crossed over a hill, the signal delivery request adopts as shown in figure 11 LM1000 high power transmission device and receiver, reflector more than hundreds of rice, can guarantee that signal sends to more than 1000 meters.
Receiver is then selected the device highly sensitive, that induction force is strong for use.Because job requirements such as this device is advanced, hit, brakes, so remote control reception, reflector will be considered demands such as the interaction, locking of push key, so be that we make structural design, are implemented the outsourcing product of having made to order by producer.
From Figure 11 and Figure 12, can see, receiver by antenna, frequency division, control and two supply pins and four same model relays totally 12 connecting terminal blocks form.Relay tip is shown in J1, and enabling signal is provided by the remote controller frequency division, and 1.2.3 often is respectively and opens, public, normally closed contact, and other J2, J3, J4 are identical.
Control circuit:
Three synchronised deicer control circuits are as shown in figure 10:
As can be seen from Fig. 10,, light, subsequently, divide duplex feeding by the luminous tube Fg1 of R1 dividing potential drop no matter be the working power that ground is served or supplied with by accumulator jar.One the tunnel through the R2 step-down, and voltage stabilizing didoe D5 voltage stabilizing is 12V, supplies with receiver of remote-control sytem and three-phase swing arm oscillating circuit; The relevant relay tip of another Lu Zejing is supplied with the 24V(motor of advancing) the forward and reverse rotation of motor.
This place of numeral before and after the figure repeat circuit node in the square frame and the corresponding terminal of receiver of remote-control sytem row are joined, because each node is comparatively directly perceived, so state no longer in detail.
The advance running of motor:
In conjunction with Figure 10 and Figure 11 and Figure 12, press 1 key when remote control transmitter, receiver is received signal, after conversion process, starting relay J1 often leaves node J1-1 closure, connects the 24V positive supply, give the motor D x left side of advancing through common point, and normally closed contact J1-2 disconnects, break away from negative pole; Connect the relay J 2 of the motor D x other end this moment and end, the closed negative supply of connecting of normally closed contact J2-2 so motor just changes, is advanced forward.
Press 2 keys when remote control transmitter, receiver is received signal, and starting relay J2 after the conversion process often opens node J2-1 closure, connects the 24V positive supply, gives the motor D x right side of advancing through common point, and normally closed contact J2-2 disconnects, and breaks away from negative pole; The relay J 1 that connects motor D x left side this moment is ended, and the closed energized negative pole of normally closed contact J1-2 is so the motor counter-rotating is advanced backward.
Dotted line Dx motor is when " mountain " shape power transmission line two is connected and uses.
