2, by setting turn hole, shaft, sliding block and dovetail groove, on the one hand the first cover board and second can be driven in mobile bar
Cover board is constantly agitated, and makes the one end of one end and the second cover board far from the first cover board of the first cover board far from the second cover board in support base
While upper sliding, the first cover board and the second cover board can be made to be supported the support of seat, prevented when mobile bar is broken, because
First cover board and the second cover board cannot be supported the support of seat and fall, and improve the emergency defence capability of the present apparatus；It is another
Aspect is also prevented from mobile bar and the first cover board and the proposition of the second cover board is changed air regulator mouth completely, keeps the first cover board and the second cover board complete
The case where being detached from Quan Conghuan air regulator mouth, so that the present apparatus is relatively reliable.
3, the present invention can play the protective effect to ventilation device, extend making for ventilation device by setting protective shell
With the service life, reduces the maintenance to ventilation device and replace number, be reduced to manpower and material resources spent by repair and replacement ventilation device, drop
Low cost.
4, the present invention passes through the upper plate in support base and multiple ventilation devices is arranged, on the one hand, can be in the first cover board and the
Two cover boards are by time, the cold air come in from ventilation device is completely into the hot-air in cable duct, in cable duct under mobile bar
Cable duct is flowed out from secondary ventilation device simultaneously, improves the replacement efficiency to the hot-air in cable duct；And it is divulging information
When device is damaged, be can not work normally, secondary ventilation device still is able to normal use, improves the emergency defence energy of the present apparatus
Power.
On the other hand, secondary ventilation device passes through setting blast cap, connecting tube, support tube, limit plate and elastic component, Neng Goushun
Hour hands make connecting tube that limit plate be driven to rotate together by rotation connection pipe, until limit plate turns to the installation with support tube
The opposite position in hole, limit plate stretches under the action of the elastic member, to the direction far from connecting tube, so that limit plate be made to pass through peace
It fills hole and stretches out support tube, to make limit plate gear on the upper surface of support base, prevent support tube under in the through-hole of support base
It falls, limit plate realizes the supporting role to support tube, and then realizes installation of the ventilation device on support base, so that ventilation device
Dismounting with support base is more convenient.
5, on the one hand the present invention can be rotated in support tube, separately by setting connecting hole and support ring convenient for connecting tube
On the one hand can also connecting tube be made to be supported in support tube, has shared the weight for the connecting tube that limit plate is born, extend this
The service life of device.
6, the present invention can rotated clockwise connecting cylinder, make to limit by setting auxiliary stopper plate and auxiliary elastic member
While plate stretches out support tube, while auxiliary stopper plate also being made to stretch out support tube, so that auxiliary stopper plate is blocked support base, to keep away
Exempt from because of extraneous severe natural situation, such as in the case where wind-force is larger, ventilation device lifts winged situation by wind and occurs, and makes ventilation dress
Set be mounted so as on support base it is stronger.
7, the present invention is by setting diversion pipe, can reduce hot-air in cable duct generate in the lower end of connecting tube because
Turbulent flow and the power loss generated, flow out the hot-air in cable duct more glibly.
8, by setting control system, voluntarily the humidity in cable duct can be monitored by humidity sensor, and
Motor is acted by controller in time, intelligence is convenient, and the labor intensity of staff is reduced, is improved efficiency, moreover,
The humidity that humidity sensor is monitored can be shown on a display screen, be checked convenient for staff.
