The labor intensity of the maintainers is lowered, and the body health of the maintainers is guaranteed.
Description
Technical field
The utility model relates to the unpowered tunnel ventilation device of a kind of intelligence.
Background technology
The tunnel inner cable gives out a large amount of heats 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 height when operation or maintainer must carry out ventilation before entering 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 to open successively well lid, and will will manually guard in important highway section, 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 situation, the exhaust air rate size, and parameter determines that can if tunnel conditions reach personnel and enter requirement etc. thus.
The utility model content
According to above deficiency of the prior art, the technical problems to be solved in the utility model is: a kind of reduction cable tunnel internal temperature is provided, improves the internal environment quality and monitors the internal environment parameter in real time, and realize the intelligent unpowered tunnel ventilation device of remote data transmission.
Intelligence provided by the utility model 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 the mounting seat, connects main shaft on the bearing support, rotating vane is set around the bearing support.
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 outside 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, connect microprocessor by circuit, are used for the information in real-time monitoring, the feedback cable tunnel.
Microprocessor is circumscribed with display.Be used for showing in real time the information in the cable tunnel.
Microprocessor communicates to connect by wireless transport module and extraneous receiving system.Wireless transport module is preferentially selected Zigbee module or other wireless data communications module such as GSM, bluetooth, GPRS etc. for use, and receiving system can be data sink commonly used at present, as mobile phone, panel computer, HPC, PC etc.
Fixedly there is over cap on the top of rotating vane, 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 utility model 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 that round-the-clock, full weather conditions turn round, and it is good to remain the tunnel internal environment.And carry out the real-time detection of temperature, capacity and oxygen content by three groups of sensors, make the maintainer grasp situation in the tunnel at any time.Reduce maintainer's labour intensity, ensured maintainer's health of human body.
Description of drawings
Fig. 1 is the utility model structural representation;
Among the figure: 1 mounting seat; 2, main shaft; 3, bearing support; 4, waveform fan blade turbine; 5, microprocessor; 6, temperature pick up; 7, air velocity transducer; 8, air borne sensor; 9, over cap; 10, display.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is 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 the mounting seat 1, connects main shaft 2 on the bearing support 3, rotating vane is set around the bearing support 3.Rotating vane is waveform fan blade turbine 4.Waveform fan blade turbine 4 is little with outside 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, connect microprocessor 5 by circuit, are used for the information in real-time monitoring, the feedback cable tunnel.Microprocessor 5 is circumscribed with display 10.Be used for showing in real time the information in the cable tunnel.
Fixedly there is over cap 9 on the top of rotating vane, 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 wind-driven naturally 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 equilibrium state when rotated.
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 can be monitored tunnel internal ventilation, temperature and air quality situation in real time, and converges data by the ZigBee Radio Transmission Technology, finally realizes 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, because the centre bearing that totally-enclosed oneself lubricates has been installed, 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 installed in 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 is sent to the data receiving platform by the GSM public network.
