Description

Technical Field

[0001] This application relates to the technical field of gas detection, and in particular to a detection device that moves autonomously according to wind direction. Background Technology

[0002] In large petrochemical enterprises, pipelines, tanks, and other equipment used to transport or store hazardous chemical raw materials pose a risk of leakage and require monitoring through safety detection technologies. For gaseous hazardous sources, current mainstream detection technologies include point detectors, line detectors, and stereoscopic imaging detectors; in terms of deployment, they can be categorized as fixed, mobile / portable, and vehicle-mounted. Each type of detector has its advantages in principle, but is also limited by the current state of technological development. In terms of detection effectiveness, stereoscopic imaging detectors > line detectors > point detectors. However, in practical applications, fixed point detectors remain the most common solution because linear or stereoscopic imaging products have not yet been developed for many gas types, and related technologies require further breakthroughs.

[0003] Fixed point or linear detectors rely on natural gas diffusion, triggering an alarm only when gas enters the detector's sensing area. In open or exposed environments, wind direction changes can cause detector failure: if the detector is upwind of the leak source, naturally diffused gas may not reach the detection area; even detectors using a suction principle have fixed intake ports and limited effective suction distance, making it difficult to fully cover risk points. Achieving comprehensive monitoring would require densely deploying detectors in all directions, significantly increasing costs. Therefore, existing fixed detection solutions suffer from passive monitoring limitations. Their reliance on natural gas diffusion makes them ill-suited to dynamic airflow changes in open or exposed environments (especially upwind leak scenarios), resulting in technical bottlenecks in spatial coverage and response efficiency. Utility Model Content

[0004] To enable point-type or linear detectors to detect gas leaks promptly, proactively, and effectively, this application provides a detection device that moves autonomously according to wind direction, employing the following technical solution:

[0005] A detection device that moves autonomously based on wind direction, comprising:

[0006] Gas detector;

[0007] The meteorological monitoring cabin is used to detect and transmit meteorological information in the monitored area.

[0008] The track is set up within the monitoring area;

[0009] A mobile mechanism, communicatively connected to the meteorological monitoring chamber, is used to receive the meteorological information and, based on the meteorological information, drive the gas detector to move along the track;

[0010] The power compartment is used to output low-voltage DC power and is electrically connected to the gas detector, the meteorological monitoring compartment and the mobile mechanism to supply power to the gas detector, the mobile mechanism and the meteorological monitoring compartment.

[0011] By adopting the above technical solution, the meteorological monitoring chamber is used to detect meteorological information in the monitoring area. The mobile mechanism drives the gas detector to move to the downwind side according to the wind direction information, or moves back and forth autonomously on the downwind side, so that the gas detector can monitor the gas leakage at different locations in real time. Since the gas detector can be driven to move according to meteorological information such as wind direction, the monitoring range of the gas detector is expanded, enabling point or linear detectors to detect gas leakage in a timely, proactive and effective manner.

[0012] Optionally, the track is a suspended track, T-shaped, with the opening facing downwards.

[0013] By adopting the above technical solutions, rainwater intrusion can be avoided, and the passage of ground equipment or personnel can be prevented.

[0014] Optionally, the detection device further includes:

[0015] An insulating plate is installed on both sides inside the track, and the insulating plate has an installation groove.

[0016] A conductive copper busbar is installed in the corresponding mounting groove, with the inner side of the conductive copper busbar lower than the outer side; the moving mechanism obtains power through the conductive copper busbar, and the power compartment is electrically connected to the conductive copper busbar.

[0017] By adopting the above technical solution, the inclined design inside the track can prevent the accumulation of sand and dust, which is beneficial to electrical conductivity and frictional motion.

[0018] Optionally, the moving mechanism includes:

[0019] Mounting rack;

[0020] A conductive copper wheel is mounted on the mounting bracket via a conductive copper shaft and abuts against the conductive copper busbar; a power supply wire is led out from the conductive copper shaft;

[0021] The geared motor is powered by the power supply wire and is mounted on the mounting bracket;

[0022] A rubber wheel abuts against the conductive copper busbar and is connected to the output shaft of the geared motor;

[0023] The main controller is powered by the power supply wire and is communicatively connected to the meteorological monitoring chamber and the remote monitoring center, and is electrically connected to the geared motor and the gas detector.

[0024] By adopting the above technical solution, the main controller autonomously controls the rotation of the geared motor based on meteorological data such as wind direction. The geared motor drives the rotation of the rubber wheel, thereby realizing the movement of the moving mechanism, which moves to the leeward side or moves back and forth within the leeward side. After the gas detector detects a gas leak, the main controller sends the gas leak information to the remote monitoring center.

[0025] Optionally, both the conductive copper wheel and the rubber wheel are tapered.

[0026] By adopting the above technical solution, it is convenient to contact the conductive copper busbar, maintain the stability of movement, and improve the passability during movement.

[0027] Optionally, the mounting bracket includes:

[0028] The upper mounting plate is used to mount the geared motor;

[0029] The lower mounting plate, connected to the upper mounting plate via a support column, is used to mount the main controller and the gas detector;

[0030] An insulating bracket is mounted on the upper mounting plate and is used to mount the conductive copper shaft.

[0031] Optionally, the detection device further includes:

[0032] The fan is installed on both sides of the mounting bracket and is oriented toward the corresponding conductive copper busbar, and is electrically connected to the main controller.

[0033] The above technical solution is used to blow away dust on the conductive copper busbar to ensure its conductivity.

[0034] Optionally, the detection device further includes:

[0035] A gas collection hood is rotatably mounted on the mounting frame and positioned at the detection end of the gas detector; the front opening of the gas collection hood is larger than the rear opening, and it is shaped like a bucket.

[0036] By adopting the above technical solution, the opening position of the gas collection hood can be adjusted according to the wind direction to ensure that the large opening faces the wind, which is beneficial for gas collection. In case of heavy rain, the gas collection hood can be adjusted in the opposite direction to protect the gas detector.

[0037] Optionally, the rear end of the gas collection hood is hinged with a cover plate, and the opening angle of the cover plate is less than 90 degrees.

[0038] By adopting the above technical solution, when the large opening faces the wind, the cover is naturally opened, allowing airflow to pass smoothly; when the small opening faces the wind, the cover is naturally closed, and the gas collection hood protects the gas detector.

[0039] Optionally, the front opening of the gas collection hood is covered with polyester fiber cotton.

[0040] By adopting the above technical solutions, the impact of wind on gas detectors can be mitigated. Polyester fiber cotton is hydrophobic, unaffected by rain, and easy to reuse.

[0041] In summary, this application has at least the following beneficial effects:

[0042] 1. The gas detector can automatically change its position according to the wind direction to achieve more effective safety monitoring and protect important facilities;

[0043] 2. Various instruments and equipment can be installed on the mobile mechanism to achieve multi-faceted information monitoring;

[0044] 3. Low cost, wide monitoring range, and timely and effective autonomous safety monitoring;

Detailed Implementation

[0053] To make the objectives, technical solutions, and advantages of the embodiments of this application clearer, the appendices of the embodiments of this utility model will be described below. Figure 1 - Appendix Figure 5 The technical solutions in the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0054] This application discloses a detection device that moves autonomously based on wind direction. (Refer to...) Figure 1 The detection device may include a gas detector 100, a meteorological monitoring chamber 200, a track 300, a moving mechanism 400, and a power chamber 500.

[0055] The gas detector 100 is an off-the-shelf product, installed on the mobile mechanism 400, to monitor gas leaks at its location in real time. Different types of gas detectors can be installed according to site requirements. The gas detector 100 is powered by the mobile mechanism 400 and communicates with it via a wired connection to transmit detection information. The gas detector 100 can change its detection direction based on its position on the track 300 for effective safety monitoring.

[0056] The meteorological monitoring cabin 200 is placed in a suitable location on-site (monitoring area), generally an open and unobstructed place, to monitor meteorological information such as wind direction, temperature, humidity, and air quality; using readily available instruments and equipment, the detected meteorological information is transmitted to the mobile agency 400 via a local wireless network such as Zigbee.

[0057] The track 300 can be arranged in different shapes, such as circular or linear, depending on the needs of the site, and the distance is determined by the area of ​​the monitoring area.

[0058] The power compartment 500 is located in a suitable location on site and can be powered by AC or solar power, outputting low-voltage DC power to supply power to the meteorological monitoring compartment 200 and the mobile mechanism 400.

[0059] After receiving meteorological information such as wind direction, the mobile mechanism 400 can drive the gas detector 100 to autonomously move along the track 300 to the leeward side, or autonomously move back and forth on the leeward side, and collect information from the gas detector 100. This information is then transmitted to a remote monitoring center via a wide-area wireless network such as CAT.1. In other embodiments, the mobile mechanism 400 can also receive other control information, such as remote control input, and perform purposeful reciprocating motion.

[0060] Reference Figure 2 The track 300 is T-shaped and installed by hoisting, hence the name "hoisted track 300". The track 300 is made of cold-rolled steel plate or aluminum profile, with the opening facing downwards to avoid rainwater intrusion.

[0061] Furthermore, insulating plates 310 are installed on both sides inside the track 300, and mounting grooves 330 are formed within the insulating plates 310. The mounting grooves 330 are used to install conductive copper busbars 320 for transmitting the positive and negative terminals of the low-voltage DC power supply. After installation, the conductive copper busbars 320 are lower inside and higher outside. The power compartment 500 is electrically connected to the conductive copper busbars 320. The insulating plates 310 prevent short circuits between the conductive copper busbars 320 and the metal casing of the track 300.

[0062] Reference Figure 3 and Figure 4 The moving mechanism 400 may include a mounting bracket 410, a conductive copper wheel 420, a geared motor 430, a rubber wheel 440, and a main controller 450 (see [link to main controller]). Figure 1 ).

[0063] The mounting bracket 410 consists of an upper mounting plate 411, a support column 413, a lower mounting plate 412, and an insulating bracket 414.

[0064] The geared motor 430 is mounted on the upper mounting plate 411 and is connected to the rubber wheel 440 through the output shaft of the reducer to drive the rubber wheel 440 to rotate; the rubber wheel 440 is tapered and abuts against the conductive copper busbar 320.

[0065] The upper mounting plate 411 is fixedly connected to the lower mounting plate 412 via a support column 413, and an insulating bracket 414 is mounted on the upper mounting plate 411. The lower mounting plate 412 is used to mount the gas detector 100. The two ends of the upper mounting plate 411 are bent and mutually restrained with the groove inside the track 300 to prevent the moving mechanism 400 from falling off during movement.

[0066] The conductive copper wheel 420 is mounted on the insulating bracket 414 via a conductive copper shaft. The conductive copper wheel 420 is tapered and abuts against the conductive copper busbar 320. A power supply wire is led out from the conductive coaxial section. The power supply wire is used to supply power to the gas detector 100, the main controller 450, and the geared motor 430.

[0067] Two sets of conductive copper wheels 420 and geared motors 430 are provided, symmetrically mounted on both sides of the upper mounting plate 411. The two conductive copper wheels 420 and two rubber wheels 440 are on the same plane. The two conductive copper wheels 420 contact different conductive copper busbars 320 respectively, thereby obtaining the positive and negative terminals of the low-voltage DC power supply. The two rubber wheels 440 also contact different conductive copper busbars 320 respectively, and are driven to rotate by the geared motor 430, thus allowing them to move forward or backward along the track 300.

[0068] The main controller 450 has a built-in microprocessor and is electrically connected to the geared motor 430 via a wired connection to control the forward or reverse rotation of the geared motor 430, thereby causing the moving mechanism 400 to move forward or backward. The main controller 450 receives meteorological information such as wind direction from the meteorological monitoring chamber 200 via local wireless communication, and autonomously controls the rotation of the geared motor 430 to move the moving mechanism 400 to the leeward side, or to move back and forth within the leeward track 300 area. The main controller 450 is connected to the gas detector 100 via a wired connection to obtain the detection information from the gas detector 100, and transmits the collected detection information, current location, and other information to the remote monitoring center via wide-area wireless communication, so that the remote monitoring center can promptly assess dangerous situations.

[0069] The conductive copper busbar 320, conductive copper wheel 420, and rubber wheel 440 are designed with an inclination to facilitate the movement of the device while it turns, and also to make it easy for the device to be accurately embedded in the track 300 during movement.

[0070] Furthermore, fans (not shown in the figure) can be installed on both sides of the upper mounting plate 411. The fans are electrically connected to the main controller 450 via a wired connection. The fans are miniature fans adapted to the detection device and are positioned towards the corresponding conductive copper busbar 320 to blow away dust on the conductive copper busbar 320 and ensure its conductivity.

[0071] Furthermore, a gas collecting hood 700 can be installed on the lower mounting plate 412. The gas collecting hood 700 is funnel-shaped and rotatably mounted on the mounting bracket 410, and is located at the detection end of the gas detector 100. The front opening of the gas collecting hood 700 is larger than the rear opening. The structure of the gas collecting hood 700 is described in reference [reference needed]. Figure 5 As shown.

[0072] The rotation of the air hood 700 can be controlled by a conventional rotation mechanism, such as a gear mechanism or a stepper motor, and the main controller 450 controls the rotation mechanism to adjust the direction of rotation.

[0073] In addition, a layer of polyester fiber cotton is covered at the front opening of the gas collection hood 700, and a cover plate (not shown in the figure) is hinged at the rear end of the gas collection hood 700. The opening angle of the cover plate is less than 90 degrees.

[0074] In addition, a camera can also be mounted on the lower mounting plate 412 to acquire images from various angles to meet safety requirements in extreme situations. The camera itself has wireless communication capabilities, and the power supply wire led out from the copper spool provides power to the camera.

[0075] The implementation principle of this embodiment is as follows:

[0076] The moving mechanism 400 is installed inside the track 300 through an opening in the track 300. The two ends of the track 300 are then sealed to prevent the moving mechanism 400 from sliding out of the track 300. The gas detector 100 for leak detection is fixed to the lower mounting plate 412, and power and signal lines are connected. The output wire of the power supply compartment is connected to the two conductive copper busbars 320 of the track 300. The moving mechanism 400 obtains power through the power supply wire led out from the conductive copper shaft. The meteorological monitoring compartment 200 sends the monitored meteorological information to the main controller 450. Based on the received meteorological information or under the control of instructions, the main controller 450 controls the geared motor 430 to rotate, thereby enabling the autonomous movement of the moving mechanism 400 and facilitating effective monitoring of facility safety by the gas detector 100. The detection information detected by the gas detector 100 is sent to the main controller 450, which then sends the detection information to a remote monitoring center.

[0077] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Any feature disclosed in this specification (including the abstract and drawings) may be replaced by other equivalent or similar features unless specifically stated otherwise. That is, unless specifically stated otherwise, each feature is only one example of a series of equivalent or similar features.
