Having some threading holes, electric power box is provided with some vent stacks 221, and vent stack upper end is internal with electric power box to be connected, and ventilation is perpendicular
Pipe is provided with ventilation transverse tube 222, and ventilation transverse tube the inner connects with vent stack lower end, and vent stack is fixed on bottom electric power box,
Electric power box includes upper box 2a and holds fixing lower box 2b with mobile jib, upper box lower ending opening, lower box upper end open,
Upper box is enclosed within outside lower box, and is slidably connected between upper box and lower box, and the slidably direction of upper box is above-below direction,
Upper box sidewall is provided with some and upper box threaded engagement lock-screw 14, and lock-screw passes upper box sidewall and contact
Lower box lateral wall, electric power box is provided with and threading hole fixing plug one to one, and fixing fork clip is in corresponding threading hole, logical
Being provided with breather check valve in gas vertical tube, the ventable direction of breather check valve is to vent stack upper end by vent stack lower end,
Crossing and be provided with some aerofluxus battens 421 in headroom, inner with the neighbouring cover bar of aerofluxus batten is hinged, and dash overhead guard is provided with
Some with aerofluxus batten returning spring 422 one to one, the upper end of returning spring is connected with dash overhead guard, aerofluxus batten outer end
Connect with the lower end of corresponding returning spring.Mobile jib is as the support section of roof rods tower structure, and base is for fixing with roof 9
(generally it is bolted, it is also possible to select the base of counter weight type, i.e. base itself is heavier, and base is directly placed on roof
As brace foundation), can arrange in electric power box transformator, optic fiber joint structure etc. the most important and need equipment to be protected or
Structure.Threading hole bottom electric power box can be used for into and out of line, and dash overhead guard then can be used for protecting electric power box, plays certain preventing
Directly shine effect, and be avoided that at the louvre of top and enter rainwater.And it is arranged at roof space above due to mobile jib body, electric power box etc.,
Ambient air circulation (wind) is more, when blowing air over mobile jib body, understands some air-flow and enters one or several ventilation transverse tube
In, then enter after vent stack inside electric power box, air leaves electric power box from top louvre after flowing through electric power box, finally discharges
To crossing headroom, coming back to the external world.So, make use of the feature that roof natural wind is more, by guiding airflow passes electricity
Inside power case, take away heat produced by each electricity consumption within electric power box, heat radiating structure, carry out on the premise of not consuming energy automatically
Heat radiation, it is to avoid the internal accumulated heat of electric power box, protects the power equipment etc. in electric power box.Electric power box space can regulate, with
Adapt to use demand, during regulation, only need to unclamp lock-screw, adjust upper box position, the most again turn lock-screw up and down, allow
Lock-screw contacts and compresses lower box lateral wall, so that fixing between upper box, lower box.Owing to steam is relatively light,
Easily rising, again due to relatively easy air intake at ventilation transverse tube, therefore top louvre plays degassing function substantially, and external dust is difficult to
From top, louvre enters electric power box；And transverse tube of ventilating is in below electric power box, and dust is after ventilation transverse tube enters, in addition it is also necessary on
Rising and just have an opportunity to enter electric power box through vent stack, therefore dust is not easy to enter electric power box from ventilation transverse tube；But it is logical
String holes is provided in bottom electric power box, and time actually used, do not ensure that each threading hole be used to (if threading hole
Interior not over electric wire, cable, optical cable etc., threading hole would not be blocked by electric wire etc.), and the threading hole being not used by is straight
Connecing and be in communication with the outside, the threading hole that dust is the most never used to enters electric power box.In this programme, in each threading hole
Being provided with fixing plug, consequently, it is possible to need to use which threading hole, take out the fixing of correspondence and fill in, remaining threading hole is then
Can keep sealed condition, thus too fast in electric power box can be avoided, dust stratification too much.Air-flow is from ventilation transverse tube, a vent stack
After entering electric power box, also have many air-flows and directly discharge from other vent stack, consequently, it is possible to radiating effect will reduce.
And in this programme, be provided with breather check valve so that all air inlet vertical tubes all can only air inlet and can not aerofluxus so that
Air-flow must be cooled down be required for moving from bottom to top, could be discharged by the top louvre of top after electric power box inside, can fill
Code insurance barrier cooling radiating effect.When exhaust airstream leaves electric power box from top louvre, finally it was expelled to headroom, came back to
During the external world, air-flow can drive aerofluxus batten to rotate along pin joint, is simultaneously used for the existence of returning spring, each aerofluxus bar
Plate all can carry out back rotation along the pin joint of self, forms the effect of " pectinid ", such that it is able to accelerate the sky that will cross in headroom
Gas discharges and improve the exhaust velocity of top louvre, and (air crossed in headroom is fanned out once, crosses headroom
Interior air pressure with regard to rapid decrease once, can form an of short duration negative-pressure air-suction process, and the wind drawn is just from top heat radiation
At hole), it is similar to the most once bleed at electric power box top, and under natural wind action, continuous air inlet bottom electric power box,
Thus supply below being formed on the whole, the effect bled of top, can the flowing velocity of heat radiation air-flow, do not increasing energy consumption
On the premise of, improve radiating effect.
Described ventilation transverse tube axis and mobile jib body axes intersect, any one ventilation transverse tube the inner is in outside this ventilation transverse tube
Between end and mobile jib body.For the ventilation transverse tube and vent stack of connection, it is (outer that ventilation transverse tube outer end is equivalent to " air inlet "
Boundary's air enters), vent stack upper end is equivalent to " gas outlet " (air is expelled to electric power box), and therefore ventilation transverse tube the inner is in
Between ventilation transverse tube outer end and mobile jib body, it is meant that " air inlet " is outwardly all the time, more conducively outside air enters ventilation horizontal stroke
Pipe, and in vent stack enters into electric power box.
Also include the shake-up cylinder 5 fixing with roof, touch cylinder top and be provided with hole 51 of reeving, touch cylinder inner bottom part and be provided with and touch
The shake-up piston 52 that dynamic cylinder is slidably connected, the slidably direction touching piston is above-below direction, is provided with shake-up drag-line with mobile jib
53, touch drag-line one end and connect mobile jib body, touch the drag-line other end and connect and touch piston, touch drag-line and reeve hole, shake-up
Cylinder inner top is provided with pressure transducer 54, touches piston and is provided with the shake-up pressure head 55 for pushing up pressure pressure sensor, touches cylinder
It is provided with the ECU that detonates being connected with pressure transducer, with mobile jib, is provided with the gas generator 11 being connected with the ECU that detonates.Described
Being provided with the limit spring 56 of at least vertical layout in touching cylinder, limit spring upper end connects the inner roof wall touching cylinder, spacing
Lower spring end connects shake-up piston-top surface.
Under the influence of the extrinsic factor such as external force collision or long neglected and in disrepair, typhoon weather, mobile jib body likely there will be
Loosen fracture, then topple over, if mobile jib body is toppled over laterally (outside roof), easily fall on the ground, cause the event of hurting sb.'s feelings, dangerous
Property is higher.If therefore mobile jib body is toppled over, it is desirable to it can swing to no man's land, inner side (in roof expanse).In this programme, when
When the fracture of mobile jib body is toppled over, if mobile jib body falls down to inner side (roof), then touch Suo Wei stress tensioning, other action does not occur.
When the fracture of mobile jib body is toppled over, if mobile jib body outwards (outside roof) is toppled over, then touch Suo Shouxian and be pulled, due to mobile jib body
The caused pulling force that falls down is very big, moves so shake-up Suo great Li can be driven to pull on shake-up piston, and limit spring is significantly received simultaneously
Contracting, touches piston driving shake-up pressure head and removes contact, top pressure pressure sensor, and signal is passed to the ECU that detonates, detonated by pressure transducer
ECU controls gas generator and detonates, and produces a large amount of gas, when gas outwards sprays, mobile jib body is had the biggest counteracting force
(propulsive thrust), such that it is able to promote internal towards roof for mobile jib body, ensures that mobile jib body and electric power box are toppled in roof, keeps away
Exempt from mobile jib body and electric power box falls to causing security incidents such as hurting sb.'s feelings outside roof.Additionally, the gas release direction of gas generator
Preferably level and towards outside roof, so can preferably provide propulsive thrust (now propulsive thrust action effect is more apparent), certainly, also
Too much restriction can not be done, as long as mobile jib body inwardly (in roof expanse) can be promoted by propulsive thrust.Gas herein is sent out
Raw device principle can identical with the gas generator principle of air bag on general-utility car (after i.e. giving signal, detonate generation gas
Body).The pressure that pressure transducer is sensed needs to reach bigger value (can be set) according to practical situation, and detonate ECU
Just can control gas generator to detonate, only change because of the pressure signal caused by the factor such as wind-force, rainwater, impact will not be produced.
Also including the rope winding wheel carrier fixing with roof, pulley yoke is provided with rope winding pulley 61, and rope winding pulley divides with touching cylinder
Being in the opposite sides of mobile jib body, be provided with auxiliary drag-line 62 with mobile jib, auxiliary drag-line is reeved hole, and auxiliary drag-line one end connects mobile jib
Body, the auxiliary drag-line other end connects shake-up piston, auxiliary guy cable rounds rope winding pulley.In aforementioned schemes, at mobile jib body outwards (towards room
Top is outer) there is safety protection function when toppling over, and when the fracture of mobile jib body, inwardly (in roof) tilt, but be not fully disconnected
Time, mobile jib body can be in inclination, be intended to the state do not fallen, and in this condition, mobile jib body loses rationally support, easily by external force
To all angles, as the big tree of same soon drop, there is the biggest potential safety hazard in (such as wind-force) band.Now, no
As directly allowed mobile jib body rupture, and fall on roof, to stop security risk, then consider further that and reinstall, construct or change
Maintenance is advisable.In this programme, when the fracture of mobile jib body, inwardly (in roof) tilt it is, due to auxiliary guy cable rounds rope winding pulley and two
End is ined succession mobile jib body and touch piston respectively, and the most auxiliary drag-line can be pulled by mobile jib body that (rope winding pulley is equivalent to serve " pulling force
Turn to " effect), and auxiliary drag-line can pull and move on shake-up piston, thus carries out jet (gas generator as aforementioned schemes
Detonate), mobile jib body inwardly (in roof) can be pushed over by propulsive thrust produced by jet.
Being provided with air jet pipe 7, air jet pipe axis horizontal and air jet pipe the inner with described mobile jib to be connected with mobile jib body, gas is sent out
Raw device is in air jet pipe, and the gas release direction of gas generator is inner to air jet pipe outer end by air jet pipe.Gas occurs
After device produces gas, although gas first meeting sprays from the gas liberation port of itself, but after leaving gas liberation port, has
A part of gas spreads out that (a large amount of gas of instantaneous generation, gas can be immediately towards at extraneous relatively low pressure immediately towards surrounding
Flowing, diffusion), thus the integrated pushing effect of mobile jib body is had substantially weakening.And in this programme, gas generator is in spray
Tracheal strips, gas is initially after the gas liberation port of gas generator sprays, moreover it is possible to through one section of air jet pipe, thus by air jet pipe
Guide, maintain overall jet-impingement direction level and towards outside roof, thus extend the action time of the propulsive thrust to mobile jib body,
Improve the promotion effect to mobile jib body.
Described air jet pipe is made up of the anti-ejector sleeve 7a interconnected and sealing tube 7b, and anti-ejector sleeve is in sealing tube and mobile jib body
Between, it being provided with sealing ball 71 in anti-ejector sleeve, sealing bulb diameter is less than anti-ejector sleeve internal diameter, and sealing tube internal diameter is along near anti-ejector sleeve extremely
Successively decreasing away from anti-ejector sleeve direction, sealing tube maximum inner diameter is consistent with anti-ejector sleeve internal diameter, and sealing tube minimum diameter is straight less than sealing ball
Footpath, anti-ejector sleeve inner tubal wall is provided with at least one elastic spacing block 72, and elastic spacing block is in sealing ball and anti-ejector sleeve inner tubal wall
Between, the sealed ball of elastic spacing block compresses, and is arranged with the protection air bag 12 being in unaerated state, on air jet pipe with mobile jib
Being provided with middle QI KOU 73, middle QI KOU is connected with protection air bag by intervalve 13.Elastic spacing block can be block rubber or by
Other elastomeric material is made.Elastic spacing block for temporary spacing seal ball, ensure at ordinary times sealing ball will not in anti-ejector sleeve with
Meaning is mobile.As it was previously stated, it is the most important and need equipment to be protected or knot to arrange transformator, fibre-optical splice etc. in electric power box
Structure, if it is toppled over together along with mobile jib body, directly fall on roof, relatively big owing to clashing into, the equipment being easily caused in electric power box
And structural failure, thus increase maintenance cost, even result in and cannot recycle.Additionally, roof has height unlike ground
Intensity, mobile jib body, electric power box clash into roof the most energetically to easily cause roof structure impaired, or cause structural failure within doors
(as ceiling structure within doors, dope layer etc. can be destroyed because of vibrations).In this programme, after gas generator is detonated, wink
Between produce a large amount of gas, gas is discharged to air jet pipe outer end by air jet pipe is inner, promotes sealing ball to move towards sealing tube simultaneously,
Until sealing ball is stuck in sealing tube, and seal sealing tube.Before sealing ball sealing lives sealing tube, gas can be through anti-ejector sleeve, envelope
Mouth pipe is ejected to the external world, and during this, mobile jib body can be pushed away in roof expanse by the produced huge propulsive thrust of gas injection
Dynamic so that mobile jib body reaches the state tilted towards roof.After sealing ball sealing lives sealing tube, gases at high pressure enter in a large number
Protection air bag, protection air bag is heaved, immediately such that it is able to buffer when the structures such as mobile jib body are fallen down to roof, it is to avoid mobile jib
When the structures such as body are fallen down, roof is impacted excessive, and reduce owing to mobile jib body clashes into, electric power box is also played protection.Protection gas
Capsule can wrap in outside the structures such as mobile jib body, electric power box, and concrete shape and covering position can be designed according to the actual requirements.Example
As, can be very big, consequently, it is possible to mobile jib body falls down together with electric power box with the width (radial dimension) after design protection airbag aeration
After, electric power box is just difficult to directly impinge roof.It is emphasized that the purpose that anti-ejector sleeve and sealing tube are set, it is simply that both profits
Carrying out jet by gas generator, promote mobile jib body, protection air bag is filled by the gas simultaneously utilizing gas generator to produce
Gas.If being not provided with anti-ejector sleeve and sealing tube structure, then, mobile jib body, protection air bag can be considered as one " overall structure ", gas
The propulsive thrust that the thrust (thrust of gas injection direction) that injection is caused and gas injection are caused is (with gas injection direction phase
Anti-thrust) can cancel out each other, be equivalent to that mobile jib body is not had impetus, the most just cannot realize mobile jib body
Promoting, and had anti-ejector sleeve and sealing tube, when sealing ball can be allowed to be in anti-ejector sleeve, gas still can discharge the external world, from
And ensure have the mobile jib body power that inwardly (in roof) promotes, and can automatically seal sealing tube subsequently, with to protection gas
