Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, the present invention is described in further detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
In order to facilitate understanding of the vehicle-mounted laser gas leakage detection system device provided by the embodiment of the present invention, an application scenario of the vehicle-mounted laser gas leakage detection system device provided by the embodiment of the present invention is first described. The following detailed description is made with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 and 2, fig. 1 is a schematic structural diagram of a vehicle-mounted laser gas leakage detection system device provided in an embodiment of the present invention, and fig. 2 is a schematic structural diagram of a protective cover provided in the embodiment of the present invention.
As shown in fig. 1 and 2, the vehicle-mounted laser gas leakage detection system device comprises a transceiver 4, a controller 5, a transceiver seat 3, a cradle head 2 and an automobile 1, wherein the cradle head 2 is detachably mounted and fixed on the outer top of the automobile 1 through a first screw 8; the transceiver seat 3 is fixedly arranged at the upper end of the holder 2 through a second screw 9 and can be disassembled in the same way; the transceiver 4 is arranged in the transceiver seat 3 and is clamped and fixed through a semicircular clamping ring 7 and can be detached; a controller 5 is provided in the car 1 and is connected to the transceiver 4 via a data line 6.
With continued reference to fig. 1 and 2, the vehicle-mounted laser gas leakage detection system device further includes a protective cover 10, wherein the protective cover 10 is fixed on the transceiver seat 3 by waterproof glue and covers the transceiver 4; the protective cover 10 is a streamline plastic steel cover with an upward arc-shaped bulge in the middle, and can enhance the wind blowing resistance in windy weather; the periphery of the bottom of the protective cover 10 is hermetically bonded with the upper end of the transceiver seat 3 through waterproof glue, so that the rainproof performance of the protective cover can be enhanced in rainy days.
In addition, horizontal channels 11 are respectively arranged at the front end and the rear end of the protective cover 10, the channels 11 are communicated with the inside and the outside of the protective cover 10, the flowing performance of air inside and outside the protective cover 10 is enhanced, the transceiver 4 has the functions of emitting laser and receiving reflected light waves, and meanwhile, the reflected light waves are converted into electric signals and transmitted to the controller 5 through the data line 6. The channel 11 opened at the front end of the protective cover 10 is opposite to the transceiving end of the transceiver 4, and the transceiver 4 can transmit laser and receive reflected light waves through the channel 11 at the front end of the protective cover 10.
Further, for preventing rainwater from entering into the protection casing 10 from the passageway 11 at both ends around the protection casing 10 and causing damage to transceiver 4 in the protection casing 10 in the rainy day, the inboard at both ends is equipped with the water drainage tank 12 that is linked together with passageway 11 respectively around the protection casing 10, water drainage tank 12 is the pipeline formula, the upper end opening is linked together with passageway 11 with the mode of cuting passageway 11 bottom, like this, even rainwater gets into passageway 11 also can cause the cutout, and finally flow into water drainage tank 12, water drainage tank 12 downward sloping extends outside protection casing 10, and like this, the rainwater of inflow passageway 11 finally can be outside water drainage tank 12 discharge protection casing 10, avoid causing the damage to transceiver 4, and guaranteed transceiver 4 normal use when the rainy day.
In the present embodiment, the controller 5 is configured to control the transmission and reception of the transceiver 4, and analyze the electrical signal transmitted by the transceiver 4 to determine whether there is a gas leakage, and the controller 5 has a gas concentration display and alarm function. The holder 2 is a rainproof holder which can rotate automatically in the horizontal plane and the vertical plane simultaneously or respectively, specifically, the holder 2 can rotate automatically in the horizontal plane around a shaft 2-1, and simultaneously, the holder 2 can rotate automatically in the vertical plane around another shaft 2-2 or respectively and independently, and drives the transceiver 4 to scan in multiple directions, so as to expand the detection range. In addition, the transceiver 4 transmits a red cursor while transmitting and receiving light waves, as shown in fig. 2 and 3, so that the position of the air leakage point can be quickly and accurately determined.
When the device works, the transceiver 4 is turned on through the controller 5, the cradle head 2 is started, and the transceiver seat 3 and the transceiver 4 are driven to carry out rotary scanning detection when the cradle head 2 rotates. The laser beam emitted by the transceiver 4 is irradiated to a target (e.g., a wall, a road, a tree, a pillar, etc.) at the other end after traversing the space above the gas pipeline or facility, and a part of the beam is returned to the transceiver 4 by the target, converted into an electrical signal by the transceiver 4, and transmitted to the controller 5 through the data line 6. In the laser beam emitted by the transceiver, the light beam with a special wavelength is easy to be absorbed by methane (main component of natural gas), and the concentration of methane in the detected space can be measured by comparing and analyzing the reflected light beam. When the measured methane concentration is higher than the calibration concentration, the controller 5 will alarm and display the concentration value. At this time, the orientation of the air leakage point can be determined according to the position of the red cursor emitted by the transceiver 4. The protective cover 10 ensures that the transceiver 4 can work normally in windy and rainy days, and the application range of the protective cover is enlarged.
The present invention is not limited to the above preferred embodiments, and any modifications, equivalent substitutions and improvements made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
