Abstract
The invention relates to an intelligent unpowered tunnel ventilation device which comprises a cable tunnel, and is characterized in that a ventilation device body is arranged at an opening of the cable tunnel. The ventilation device body comprises a mounting base, a bearing block is arranged in the mounting base and is connected with a main shaft, and rotary blades are arranged on the periphery of the bearing block. According to the intelligent unpowered tunnel ventilation device, natural wind power and temperature difference inside and outside the tunnel cause air thermal convection to drive a worm wheel to rotate, so the operation under all-weather conditions is achieved, and good environment inside the tunnel can be always maintained. Three groups of sensors are adopted to carry out real-time detection on the temperature, air displacement and oxygen content, and enable maintainers to master the conditions in the tunnel at any time. The intelligent unpowered tunnel ventilation device reduces labor intensity of the maintainers, and ensures physical health of the maintainers.
Description
Technical field
The present invention relates to the unpowered tunnel ventilation device of a kind of intelligence.
Background technology
The tunnel inner cable gives out amount of heat when moving, if the tunnel ventilation effect is undesirable, the tunnel internal temperature just constantly raises, and reduces the current-carrying capacity of cable run, causes expending of the energy; Humid environment in the cable tunnel, flammable, pernicious gas content is high, must carry out ventilation before operation or maintainer enter the tunnel, otherwise may damage personnel.
Current tunnel ventilation generally adopts natural ventilation or mechanical ventilation, and these two kinds of methods all need manually open manhole cover successively, and will will manually guard at Important Sections, in case unexpected, method efficient is low, and the inside and outside gas of short time inner tunnel can not get thorough exchange.Even and isolated blower fan apparatus has carried out tunnel ventilation, but operation, maintainer can not in time understand the real time status of inside, cable tunnel, as temperature height, Air Quality, the exhaust air rate size, and parameter determines that can if tunnel conditions reach personnel and enter requirement etc. thus.
Summary of the invention
According to above deficiency of the prior art, the technical problem to be solved in the present invention is: a kind of reduction cable tunnel internal temperature is provided, improves internal environment quality and Real-Time Monitoring internal environment parameter, and realize the intelligent unpowered tunnel ventilation device of remote data transmission.
Intelligence provided by the present invention is unpowered tunnel ventilation device, comprise the cable tunnel, it is characterized in that, the opening part of cable tunnel is provided with ventilation installation, described ventilation installation comprises mounting seat, bearing support is installed in mounting seat, connects main shaft on bearing support, the bearing support surrounding arranges rotating vane.
Described rotating vane is waveform fan blade turbine, and main shaft is the central axis of waveform fan blade turbine, and the two ends of main shaft all are equipped with totally-enclosed bearing.Waveform fan blade turbine and external contact area are little, use safety, and the life-span is long.Totally-enclosed bearing is all installed at the two ends of main shaft, and the oneself is lubricated, makes turbine rotation more flexible.
Mounting seat inside is provided with monitoring device, and described monitoring device comprises air borne sensor, air velocity transducer and temperature pick up, and the sensor all is connected with microprocessor.These three kinds of sensors are fixedly installed in the cable tunnel, by the connection microprocessor, are used for the information in Real-Time Monitoring, feedback cable tunnel.
Microprocessor is circumscribed with display.Be used for showing in real time the information in the cable tunnel.
Microprocessor is by wireless transport module and the communication connection of extraneous receiving system.Wireless transport module is preferentially selected Zigbee module or other wireless data communication module such as GSM, bluetooth, GPRS etc., and receiving system can be data sink commonly used at present, as mobile phone, panel computer, HPC, PC etc.
The top of rotating vane is fixed with over cap, and over cap is connected with mounting seat by dowel.Over cap can prevent that sleet dust or other foreign material are to the infringement of this device.
Intelligence provided by the present invention is unpowered tunnel ventilation device by the air thermal convection current that natural wind and tunnel inside and outside temperature difference cause, promotes the turbine rotation, realizes round-the-clock, full weather conditions running, remains that the tunnel internal environment is good.And carry out the real-time detection of temperature, capacity and oxygen content by three groups of sensors, make the maintainer grasp at any time situation in the tunnel.Reduce maintainer's labour intensity, ensured maintainer's health of human body.

The specific embodiment
Below in conjunction with accompanying drawing, embodiments of the invention are described further:
Intelligent unpowered tunnel ventilation device as shown in Figure 1 comprises the cable tunnel, and the opening part of cable tunnel is provided with ventilation installation, described ventilation installation comprises mounting seat 1, bearing support 3 is installed in mounting seat 1, connects main shaft 2 on bearing support 3, bearing support 3 surroundings arrange rotating vane.Rotating vane is waveform fan blade turbine 4.Waveform fan blade turbine 4 is little with the external contact area, uses safety, and the life-span is long.Mounting seat 1 inside is provided with monitoring device, and described monitoring device comprises air borne sensor 8, air velocity transducer 7 and temperature pick up 6, and the sensor all is connected with microprocessor 5.These three kinds of sensors are fixedly installed in the cable tunnel, by connection microprocessor 5, are used for the information in Real-Time Monitoring, feedback cable tunnel.Microprocessor 5 is circumscribed with display 10.Be used for showing in real time the information in the cable tunnel.
The top of rotating vane is fixed with over cap 9, and over cap 9 is connected with mounting seat 1 by dowel.Over cap 9 can prevent that sleet dust or other foreign material are to the infringement of this device.
Utilize nature air convective principles or naturally wind-driven waveform fan blade turbine.The inner bearing support of installing of mounting seat 1 has five spoke back shafts, can fully disperse stressedly, makes the turbine part be in when rotated equilibrium state.
Operating principle:
This device is with after the cable tunnel air outlet closely is connected, and the air thermal convection current that utilizes natural wind or tunnel inside and outside temperature difference to cause utilizes centrifugal force and underbalance effect that stale hot air in the tunnel is discharged thereby promote waveform fan blade turbine.Intelligent monitoring device energy Real-Time Monitoring tunnel internal ventilation, temperature and Air Quality, and converge data by the ZigBee Radio Transmission Technology, finally realize the remote data transmission by the GSM public network.
The course of work:
Waveform fan blade turbine 4 has strengthened contacting and angle of flabellum and wind, mounting seat 1 is with after the cable tunnel air outlet closely is connected, due to the centre bearing of totally-enclosed oneself being installed lubricating, can uninterruptedly rotate more than 0.5 ℃ at gentle breeze or the internal-external temperature difference of wind speed 2m/s.The air thermal convection current that utilizes natural wind and tunnel inside and outside temperature difference to cause promotes the rotating vane rotation.When rotating vane rotates, air velocity transducer 7 just can carry out reading, with be arranged on temperature pick up 6 and air borne sensor 8 analog quantitys in the tunnel and passed through the A/D conversion and pass to the microprocessor with the wireless biography chip of ZigBee, and after passing biography through the ZigBee wireless network, each well head data are sent to the data receiver platform by the GSM public network.
