Description

Technical Field

[0002] With the rapid development of the national economy, the demand for energy has also increased, and pipeline transportation has developed rapidly. Oil and gas pipelines are extremely dangerous because of the transportation and storage media inside them. Once a leak or explosion occurs, it will not only pose a huge threat to the pipeline itself, the station, the valve room, but also to the surrounding personnel, buildings and the environment above the buried pipeline. For this reason, pipelines that transport flammable gases need to be patrolled, supervised and repaired every day. Especially when construction is carried out above buried pipelines, full supervision is required to prevent the oil and gas pipelines from being damaged during construction, and effective measures are not taken in time, resulting in dangerous flammable gas leaks. However, manual supervision in the field is time-consuming, labor-intensive and inefficient. Utility Model Content

DETAILED DESCRIPTION

[0041] Figure 1 It is a three-dimensional structural schematic diagram of a field self-propelled combustible gas monitoring device 1 shown in an embodiment; Figure 2 for Figure 1 The schematic structural diagram of the field self-propelled combustible gas monitoring device 1 from one viewing angle is a schematic structural diagram from a viewing angle facing the third side surface 23 of the box body 20; Figure 3 for Figure 1 The schematic structural diagram of the field self-propelled combustible gas monitoring device 1 shown in another perspective is a schematic structural diagram from a perspective facing the fourth side surface 24 of the box body 20; Figure 4 for Figure 1 The structural schematic diagram of the field self-propelled combustible gas monitoring device shown is a structural schematic diagram from another perspective, which is a perspective facing the direction of the second side surface 22 of the box body 20.

[0042] like Figure 1-4 As shown, the field self-propelled combustible gas monitoring device 1 provided by the present application includes a tracked vehicle 10, a box 20, a lifting rod 30, a pan-tilt 31, an alarm 41, and a combustible gas monitor 40 and a camera 42 arranged above the pan-tilt 31. A platform 11 is arranged on the top of the tracked vehicle 10; the box 20 is arranged on the top of the platform 11; the lifting rod 30 is arranged on the top of the platform 11, and the lifting rod 30 can move up and down relative to the platform 11; the pan-tilt 31 is arranged on the top of the lifting rod 30, and the pan-tilt 31 can rotate relative to the lifting rod 30, and a combustible gas monitor 40 and a camera 42 are arranged on the top of the pan-tilt 31, the combustible gas monitor 40 is used to monitor the combustible gas content in the environment, and the camera 42 is used to collect image information in the environment; the alarm 41 is arranged on the box 20, and is used to issue a warning if the combustible gas monitor 40 detects that the combustible gas concentration in the environment exceeds the threshold.

[0043] Compared with the related art, the field self-propelled combustible gas monitoring device 1 provided by the present application has the following beneficial effects: the field self-propelled combustible gas monitoring device 1 provided by the present application comprises a tracked vehicle 10, a box 20, a lifting rod 30, a pan-tilt 31, an alarm 41, and a combustible gas monitor 40 and a camera 42 arranged above the pan-tilt 31. By setting the tracked vehicle 10, the combustible gas monitoring device 1 can be made to walk on uneven ground in the field and can bear a large load. By setting the platform 11 and the box 20, it is convenient to set the lifting rod 30, the pan-tilt 31 and the alarm 41. By setting the lifting rod 30, the lifting rod 30 can be moved up and down relative to the platform 11, so that the pan-tilt 31 and the combustible gas monitor 40 and the camera 42 arranged on the pan-tilt 31 can be raised to a higher position, and the pan-tilt 31 can be rotated relative to the lifting rod 30, which can increase the monitoring range of the combustible gas monitor 40 and the acquisition range of the camera 42. By setting the alarm 41, when the combustible gas monitor 40 detects that the combustible gas in the environment exceeds the threshold, the alarm 41 issues a warning to remind of the combustible gas leakage, so as to facilitate timely measures to avoid the expansion of danger.

[0044] In this embodiment, the combustible gas monitor 40 is a non-contact combustible gas monitor 40, and the detection principle is the laser absorption spectrum principle. The combustible gas monitor 40 includes a transmitting module and a receiving module. When the combustible gas monitor 40 is working, the transmitting module emits a detection laser of a specific wavelength to the outside. After the detection laser encounters a reflector, diffuse reflection occurs, and part of the laser returns to the receiving module of the combustible gas monitor 40. In the light beam path, if there is an air mass formed by a combustible gas leak, the air mass will absorb the detection laser, and the ratio of the amount of unabsorbed light to the amount of absorbed light is in a functional proportional relationship with the concentration of the air mass. The concentration of the air mass can be inferred by calculating the ratio.

[0045] The combustible gas monitor 40 is arranged on the pan / tilt platform 31 so that the combustible gas monitor 40 can rotate on the top of the lifting rod 30 so that the combustible gas monitor 40 can emit detection lasers in different directions, thereby increasing the monitoring range of the combustible gas monitor 40 and facilitating timely detection of combustible gas leaks.

[0046] In this embodiment, the monitoring device 1 includes an air quality detector 45, which is arranged on the box 20 and can detect the air quality in the environment, such as detecting the O2 concentration, H2S concentration, CO concentration, etc. in the air. By setting up the air quality detector 45, the air quality in the construction environment can be monitored while monitoring combustible gases.

[0047] The camera 42 is arranged on the top of the pan-tilt head 31 and is located below the combustible gas monitor 40. The combustible gas monitor 40 is located above the camera 42. Because the volume of the combustible gas monitor 40 is smaller than that of the camera 42, such an arrangement facilitates the stability of the fixed connection between the combustible gas monitor 40 and the camera 42, and the fixed connection structure between the camera 42 and the pan-tilt head 31.

[0048] In some preferred embodiments, the collection port of the camera 42 is arranged in the same direction as the collection port of the combustible gas monitor 40, so that the camera 42 and the combustible gas monitor 40 can rotate synchronously and in the same direction. When the combustible gas monitor 40 detects that the combustible gas concentration in a certain direction exceeds a threshold value, the collection port of the camera 42 is facing in that direction, so that the camera 42 can collect image information in that direction while the combustible gas monitor 40 can also sense the concentration of the combustible gas in that direction in real time and obtain the concentration change of the combustible gas in that direction.

[0049] In this embodiment, a support plate 32 is provided on the top of the lifting rod 30, and a pan / tilt platform 31 is provided on the top of the support plate 32. A wind speed measuring instrument 43 is also provided on the top of the support plate 32 for measuring the wind direction and wind speed in the environment. A rangefinder is provided on the bottom of the support plate 32, and the rangefinder may be a laser rangefinder, and the rangefinder is used to measure the distance between the support plate 32 and the top of the box 20.

[0050] By setting a support plate 32 to provide support for the pan-tilt head 31 and the camera 42 and combustible gas monitor 40 located on the top of the pan-tilt head 31, and by setting an anemometer 43 to measure the wind direction and wind speed in the environment, it is convenient to set the field self-propelled combustible gas monitoring device 1 at the downwind position. Because once the combustible gas leaks, it will move in the downwind direction under the action of the wind. Compared with setting the combustible gas monitor 40 at the upwind position, setting the combustible gas monitor 40 at the downwind position can sense the combustible gas leakage and alarm faster, thereby improving the timeliness of combustible gas monitoring. By setting a rangefinder, it is convenient to grasp the height of the lifting rod 30, and set the combustible gas monitor 40 and the camera 42 located on the top of the lifting rod 30 at a predetermined height.

[0051] In some preferred embodiments, the pan-tilt head 31 is disposed at the middle position of the top of the support plate 32, a support portion 321 is provided on one side of the support plate 32, the support portion 321 extends downward from one side of the support plate 32 and extends in a direction parallel to the support plate 32, and the anemometer 43 is an ultrasonic anemometer 43 and is disposed on the top of the support portion 321.

[0052] Such arrangement enables the pan-tilt 31 to be located in the middle of the top of the lifting rod 30, so that the center of gravity of the pan-tilt 31 coincides with the center of gravity of the lifting rod 30, thereby improving the support capacity of the lifting rod 30 for the pan-tilt 31. The anemometer 43 is an ultrasonic anemometer 43, which does not need to rotate when measuring wind speed and wind direction, so it does not need to be arranged above the pan-tilt 31. The ultrasonic anemometer 43 is arranged on the support portion 321, and the position of the support portion 321 is lower than the position of the support plate 32, so that the pan-tilt 31 can be prevented from touching the ultrasonic anemometer 43 when it is pitched and rotated. The length of the support plate 32 can be reduced without interfering with the pan-tilt 31 and the ultrasonic anemometer 43.

[0053] The monitoring device 1 includes a wind power generation component 50, a solar power generation component and a battery. The wind power generation component 50 and the solar power generation component are connected to the battery to provide electrical energy to the battery. When the monitoring device 1 is in the wild and it is inconvenient to charge the battery through the mains, the battery can be charged by the wind power generation component 50 and the solar power generation component to solve the problem of energy supply in the wild. The wind power generation component 50 includes a support rod 51 and a fan blade 52 located at the top of the support rod 51, and the support rod 51 is partially located in the box 20. The solar power generation component includes a solar panel 60, which is tilted on the outer wall of the box 20, and the solar panel 60 and the support rod 51 are located on different sides of the box 20.

[0054] The support rod 51 is partially located in the box 20, so that the support rod 51 and the box 20 share a part of the space of the platform 11, which can save the space of the platform 11 and improve the space utilization rate of the platform 11. The solar panel 60 is obliquely arranged on the outer wall of the box 20, not arranged on the platform 11, and does not occupy the space on the top of the platform 11, thereby improving the space utilization rate of the platform 11, thereby making the monitoring device 1 small in size and compact in structure.

[0055] In some preferred embodiments, the solar panel 60 is detachably connected to the housing 20. When the monitoring device 1 is located in an environment where there is a mains supply, the solar panel 60 can be removed from the housing 20. When the monitoring device 1 is located in an environment where there is no mains supply for a long time, the solar panel 60 can be installed on the housing 20. It is also convenient to change the specifications and size of the solar panel 60 according to the sunshine conditions in the environment. For example, in winter, when the sunlight is weak and the sunshine time is short, a larger solar panel 60 can be used. In summer, when the sunlight is strong and the sunshine time is long, a smaller solar panel 60 can meet the requirements.

[0056] In some preferred embodiments, the solar panel 60 is arranged on the side of the box 20 facing away from the moving direction of the crawler 10. Such an arrangement can prevent the solar panel 60 from touching obstacles and causing damage to the solar panel 60 during the moving process of the crawler 10. In this embodiment, the top of the platform 11 is rectangular, and the bottom of the box 20 is also rectangular. The bottom of the box 20 is consistent with the top of the platform 11 in shape and size. Such an arrangement can make the box 20 fully utilize the space on the top of the platform 11, and when the solar panel 60 is tilted on the box 20, the solar panel 60 does not occupy the space of the platform 11.

[0057] The middle position of the solar panel 60 in the height direction is connected to the box 20, the bottom of the solar panel 60 is inclined downward and extends beyond the platform 11, and the top of the solar panel 60 is inclined upward and extends beyond the box 20. In this way, when the volume of the box 20 is fixed, the area of ​​the solar panel 60 can be expanded and the power generation of the solar panel 60 can be increased. In some preferred embodiments, the side of the box 20 facing the direction of travel of the crawler 10 and the side facing away from the direction of travel of the crawler 10 are provided with an inclined surface 25 inclined toward the middle of the box 20 relative to the vertical direction. Providing the inclined surface 25 on the side facing away from the direction of travel of the crawler 10 can expand the contact surface between the box 20 and the solar panel 60, and better support the solar panel 60. Providing the inclined surface 25 on the side facing the direction of travel of the crawler 10 can reduce the edges and corners of the box 20 in this direction, so as to avoid damage to objects or injury to personnel during the movement of the box 20. The front side of the solar cell panel 60 faces away from the box body 20 , so that the front side of the solar cell panel 60 faces the outside of the box body 20 , so as to receive sunlight and generate electricity.

[0058] In some preferred embodiments, the box 20 is a rectangular box, including a first side surface 21 and a second side surface 22 opposite to each other in the traveling direction of the crawler 10, a third side surface 23 and a fourth side surface 24 connecting the first side surface 21 and the second side surface 22. The solar panel 60 is arranged on the first side surface 21, and the support rod 51 is located at the vertex between the second side surface 22 and the third side surface 23. In this way, the support rod 51 can be located at one of the two vertex angles farthest from the solar panel 60, and when the solar panel 60 and the support rod 51 do not interfere with each other, the distance that the solar panel 60 extends into the box 20 can be increased, thereby increasing the area of ​​the solar panel 60.

[0059] In this embodiment, the monitoring device 1 further includes a fill light 44, which is disposed on the top of the box 20 and located at the top angle between the second side surface 22 and the fourth side surface 24. The fill light 44 is provided to provide illumination for the camera 42 to collect images in a dark environment. In some embodiments, a fill light gimbal is provided under the fill light 44, and the direction of the fill light 44 can be adjusted so that the direction of the fill light 44 is consistent with the direction of the camera 42. By arranging the fill light 44 at the top angle between the third side surface 23 and the fourth side surface 24, the fill light 44 can be far away from the support rod 51 and the solar panel 60, so as to prevent the light emitted by the fill light 44 from being blocked by the support rod 51, the fan blade 52 or the solar panel 60, thereby affecting the fill light effect.

[0060] In this embodiment, the alarm 41 includes an audible and visual alarm 411 and a loudspeaker 412. The audible and visual alarm 411 can not only emit an alarm light but also emit an alarm sound, which can better remind the on-site personnel that there is a flammable gas leak. The loudspeaker 412 can be set to expand the scope of the reminder when there is no one on the scene. The audible and visual alarm 411 is suspended at the top of the box 20 and is located at the top angle between the second side 22 and the third side 23. In this way, the audible and visual alarm 411 can protrude from the box 20 and is not blocked by the solar panel 60 and the support rod 51, so that the alarm light can be seen from different directions. The loudspeaker 412 is located at the top of the box 20 and is set close to the second side 22. In this way, the loudspeaker 412 is close to the audible and visual alarm 411, reducing the length of the connecting line between the loudspeaker 412 and the audible and visual alarm 411.

[0061] In order to ensure that the fan blades 52 and the solar panel 60 do not interfere with the pan head 31 disposed on the top of the lifting rod 30 when the lifting rod 30 is in the retracted state and the lifting rod 30 is in the extended state, that is, when the length of the lifting rod 30 is the shortest and when the length of the lifting rod 30 is the longest, the position of the top of the fan blade 52 is lower than the lowest position of the pan head 31 when the lifting rod 30 is in the retracted state. The position of the top of the solar panel 60 is lower than the lowest position of the pan head 31 when the lifting rod 30 is in the retracted state. When a support plate 32 is disposed on the top of the lifting rod 30 and the pan head 31 is disposed on the support plate 32, the position of the top of the fan blade 52 is lower than the lowest position of the support plate 32 when the lifting rod 30 is in the retracted state. The position of the top of the solar panel 60 is lower than the lowest position of the support plate 32 when the lifting rod 30 is in the retracted state.

[0062] In order to prevent the fill light 44 set on the box body 20 from affecting the rotation of the fan blades 52, in some preferred embodiments, the orthographic projection of the fan blades 52 on the top surface of the box body 20 does not overlap with the orthographic projection of the fill light 44 on the top surface of the box body 20, the fan blades 52 are at a certain distance from the fill light 44, the fan blades 52 are not located above the fill light 44, or the bottom of the fan blades 52 is higher than the top of the fill light 44. In this way, even if the fan blades 52 are located above the fill light 44, the fill light 44 will not affect the rotation of the fan blades 52 because there is still a certain distance from the fill light 44.

[0063] In order to prevent the loudspeaker 412 disposed on the box 20 from affecting the rotation of the fan blades 52, in some preferred embodiments, the orthographic projection of the fan blades 52 on the top surface of the box 20 does not coincide with the orthographic projection of the loudspeaker 412 on the top surface of the box 20, or the bottom of the fan blades 52 is located higher than the top of the loudspeaker 412.

[0064] A lifting rod driving part, a fuel generator, a cable spool and a distribution box are arranged inside the box body 20. The lifting rod 30 can be a pneumatic lifting rod 30 or a hydraulic lifting rod 30. When the lifting rod 30 is a pneumatic lifting rod 30, the lifting rod driving part includes an air pump. When the lifting rod 30 is a hydraulic lifting rod 30, the lifting rod driving part includes a hydraulic device. This application does not limit this.

[0065] In this embodiment, a pneumatic lifting rod 30 is used. When the lifting rod 30 is in a retracted state, the length of the lifting rod 30 is 2.5-3 meters. When the lifting rod 30 is in an extended state, the length of the lifting rod 30 can reach 6 meters, and the lifting length is relatively long. The pneumatic lifting rod 30 can rise to a higher height than the hydraulic lifting rod, and the lifting speed is fast. The use of the pneumatic lifting rod 30 can also reduce the dead weight of the lifting rod 30, thereby reducing the load of the crawler vehicle 10.

[0066] A cable spool is provided so that when there is mains access near the monitoring device 1, but the mains access point is far away from the monitoring device 1, the cable spool is taken out from the box 20 and used as an extension line to charge the battery with mains. A fuel generator is provided so that when there is no mains access and the wind power generation component 50 and the electricity generated cannot meet the use demand, the fuel generator is taken out from the box 20 and the battery is charged by the fuel generator.

[0067] The distribution box is equipped with a wind-solar hybrid controller, which can coordinate wind power generation and solar power generation to improve the amount and quality of wind power generation and solar power generation. The box 20 also includes an electric energy input switch and an electric energy output switch. The electric energy input switch includes a city power access switch, a fuel charging access switch, a wind power generation access switch, and a solar power generation access switch. When each switch in the electric energy input switch is turned on, the battery can be charged in the corresponding way, and when the output switch is turned on, the battery can output electric energy to the outside.

[0068] A plurality of windows 26 are provided on the second side surface 22 and the third side surface 23, so that the windows 26 can be opened to operate the lifting rod drive, the fuel generator, the cable spool and the distribution box arranged in the box body 20.
