Description

Technical Field

[0001] This utility model relates to the field of gas leak detection technology, and in particular to an intelligent gas detection device. Background Technology

[0002] Since gas is mostly transported through pipelines, leak detection is crucial to ensure gas safety.

[0003] Currently, gas pipeline or valve inspection in steel enterprises generally relies on manual inspection, drone inspection, or track-mounted inspection vehicles. However, manual inspection often faces challenges due to limitations: personnel cannot easily reach higher sections of the gas pipeline, and the confined space inside underground trenches makes access difficult. In the event of a gas leak, the high gas concentration inside these trenches poses a significant risk of poisoning to personnel, creating a serious safety hazard. Track-mounted inspection vehicles require tracks, increasing installation and maintenance costs. Drone inspections, on the other hand, generate significant airflow, which can introduce measurement errors and create the risk of gas leaks. Therefore, it is necessary to provide a safe gas detection device that saves costs and improves inspection efficiency.

[0004] Therefore, we propose an intelligent gas detection device. Utility Model Content

[0005] The present invention aims to solve the technical problems existing in the prior art and provide an intelligent gas detection device.

[0006] To achieve the above objectives, this utility model adopts the following technical solution: an intelligent gas detection device, comprising:

[0007] The detector body has two mounting bases fixedly installed on its bottom.

[0008] The walking structure is detachably installed at the bottom of the detector body to support the detector body to move on the pipeline. The walking structure includes a frame, magnetic wheels, a geared motor, a supplementary light and a camera. The frame is locked to the detector body with screws. Several magnetic wheels are rotatably arranged at the bottom of the frame. The geared motor is fixedly connected to the frame. The output shaft of the geared motor is fixedly connected to the magnetic wheels. The supplementary light and the camera are both fixedly installed on the same side of the detector body.

[0009] A clamping structure is detachably mounted at the end of the mounting base for installation. The clamping structure includes a jaw, an anti-slip pad, and an anti-slip groove. The jaw is detachably connected to the mounting base. The jaw forms an open ring. An anti-slip pad is fixedly mounted on the circumferential surface of the jaw, and the anti-slip pad has an anti-slip groove.

[0010] A pushing structure is set on one side of the detector body to push the gripper to deform and close.

[0011] In a preferred embodiment of the present invention, the clamping structure further includes a slot and a plug, the end of the mounting base has a slot, the plug is fixedly connected to the gripper, and the plug is inserted into the slot.

[0012] In a preferred embodiment of this utility model, the slot is a rectangular hole, and the insert block is interference-fitted with the slot.

[0013] In a preferred embodiment of this utility model, the mounting base forms a U-shaped rod, and two mounting bases are provided on both sides of the detector body, which are diagonally distributed along the detector body. The bottom of the mounting base is provided with a mounting groove.

[0014] In a preferred embodiment of this utility model, the gripper is formed into a C-shaped rod, and two integrally formed baffles are symmetrically provided at the end of the gripper opening. The baffles are arc-shaped and extend away from the gripper.

[0015] In a preferred embodiment of this utility model, the pushing structure includes an abutting rod, an upper pull rod, and an adjusting screw. The upper pull rod is slidably connected to the detector body, the abutting rod is fixedly connected to the upper pull rod, and the adjusting screw is rotatably connected to the detector body and threadedly connected to the upper pull rod.

[0016] In a preferred embodiment of this utility model, the abutment rod is a cylinder, and the abutment rod is tangent to the outer circumferential surface of the gripper. The top of the upper pull rod is provided with a threaded hole, and the adjusting screw is threadedly connected to the threaded hole of the upper pull rod. The side wall of the detector body is provided with two ear plates, the adjusting screw is rotatably connected to one of the ear plates, and the upper pull rod is slidably connected to the other ear plate.

[0017] This utility model provides an intelligent gas detection device. It has the following beneficial effects:

[0018] 1. This intelligent gas detection device enables remote control of its movement via a mobile app, allowing the walking mechanism (magnetic wheel to prevent falling) to move along the outer surface of the gas pipeline. 3D vision provides real-time observation of position changes, and the device automatically detects and transmits the CO index of the gas over long distances. This allows for timely detection of gas leaks and prompt handling of leaks, replacing manual inspections with high efficiency and safety. Compared to drone inspections, it ensures higher detection accuracy.

[0019] 2. This intelligent gas detection device uses two grippers installed at the ends of two mounting bases. Since the two grippers are mirror-distributed, meaning their openings face each other, and the anti-slip grooves on the inner walls of the two anti-slip pads have opposite thread directions, when the gas pipeline is inserted into the anti-slip pads, the two grippers apply pressure to the anti-slip pads. Combined with the anti-slip grooves with opposite spiral directions, this ensures good contact between the anti-slip pads and the pipeline, suppressing radial and circumferential displacement between the pipeline and the anti-slip pads. This guarantees the stability of the detector body installation while maintaining ease of installation, enabling multi-point installation and detection.

[0020] 3. This intelligent gas detection device allows for the detachable installation of the gripper and the mounting base. The gripper can be installed by inserting the plug into the slot. The bottom of the mounting base also has an installation groove. Without installing the gripper, the mounting base can be directly fixed to the cabinet or wall by screws passing through the installation groove. After installing the gripper, the detector body can be fixed to the pipeline by the clamping action between the gripper and the pipeline. It has a flexible installation method and is less limited by the installation location.

[0021] 4. This intelligent gas detection device, by inserting the upper pull rod into the limiting groove and threadedly connecting it to the adjusting screw, and rotating the adjusting screw to pull up the upper pull rod, causes the contact rod to push against the outer circumference of the two grippers. The contact rod is located below the two grippers. The upward movement of the contact rod causes the grippers to deform and close, thereby increasing the squeezing force of the grippers on the anti-slip pad, strengthening the adhesion between the anti-slip pad and the pipeline, and further improving the limiting effect after the detector body is installed.

[0029] A smart gas detection device, such as Figure 1 As shown, it includes:

[0030] The detector body 10 has two mounting bases 11 fixedly installed on its bottom.

[0031] like Figure 6 As shown, the walking structure is detachably installed at the bottom of the detector body 10 to support the detector body 10 in moving on the pipeline. The walking structure includes a frame 40, magnetic wheels 42, a reduction motor 41, a supplementary light 43, and a camera 44. The frame 40 is locked to the detector body 10 by screws. Several magnetic wheels 42 are rotatably arranged at the bottom of the frame 40. The reduction motor 41 is fixedly connected to the frame 40, and the output shaft of the reduction motor 41 is fixedly connected to the magnetic wheels 42. The supplementary light 43 and the camera 44 are both fixedly installed on the same side of the detector body 10.

[0032] Circuit section: The lower-level machine uses the ESP32CAM microcontroller and the ESP32CAM camera module, which adopts DIP packaging, low-power dual-core 64-bit CPU with a main frequency of up to 240MHz, integrates the OV2640 camera, supports STA / AP / STA+AP working modes, and supports WiFi image upload.

[0033] The DC geared motor uses TB6612 as the drive circuit, and is powered by a 12V rechargeable lithium battery.

[0034] When the robot needs to move, the host computer sends a control command, which is received by the ESP32CAM through its WIFI interface. The ESP32CAM outputs high / low levels through the corresponding IO ports to drive the TB6612 motor to rotate forward or backward.

[0035] The microcontroller program was designed using the Arduino integrated development environment. The program design included setting the parameters of the OV2640 camera, configuring UDP communication, uploading image data, and controlling the drive motor.

[0036] The ESP32CAM's task is to receive robot movement commands from a mobile app and transmit captured image data to the app via Wi-Fi. To accomplish this task, the program includes establishing and connecting to the Wi-Fi network, camera initialization, opening the UDP protocol listening port, and sending captured image data.

[0037] The gas detection device can achieve CPU communication and long-distance transmission.

[0038] This solution enables remote control of the vehicle via a mobile app, allowing the walking mechanism (magnetic wheels to prevent falling) to move along the outer surface of the gas pipeline. 3D vision provides real-time observation of position changes, and automatic gas detection measures the CO index of the gas in real time and transmits the data over long distances. This allows for timely detection of gas leaks and prompt handling of leaks, replacing manual inspections with high efficiency and safety. Compared to drone inspections, it ensures higher detection accuracy.

[0039] like Figure 2 and Figure 3 As shown, the clamping structure is detachably mounted at the end of the mounting base 11 for installation. The clamping structure includes a jaw 20, an anti-slip pad 21, and an anti-slip groove 22. The jaw 20 is detachably connected to the mounting base 11. The jaw 20 forms an open ring. The anti-slip pad 21 is fixedly mounted on the circumferential surface of the jaw 20. The anti-slip pad 21 has an anti-slip groove 22. The mounting base 11 forms a U-shaped rod. Two mounting bases 11 are provided on both sides of the detector body 10, which are diagonally distributed along the detector body 10. The bottom of the mounting base 11 has a mounting groove 25. The jaw 20 forms a rod with a C-shaped cross section. Two integrally formed baffles are symmetrically provided at the opening end of the jaw 20. The baffles are arc-shaped and extend away from the jaw 20.

[0040] In this scheme, two grippers 20 are installed at the ends of the two mounting bases 11. Since the two grippers 20 are mirror-distributed, that is, the openings of the two grippers 20 are set opposite to each other, and the anti-slip grooves 22 opened on the inner walls of the two anti-slip pads 21 have opposite thread directions, when the gas pipeline is inserted into the anti-slip pads 21, the two grippers 20 apply a squeezing force to the anti-slip pads 21. With the anti-slip grooves 22 having opposite spiral directions, the anti-slip pads 21 can form a good contact force with the pipeline, suppressing radial and circumferential displacement between the pipeline and the anti-slip pads 21, ensuring the stability of the detector body 10 during installation, while maintaining the convenience of installation.

[0041] like Figure 4 and Figure 5As shown, the clamping structure also includes a slot 23 and a plug 24. The end of the mounting base 11 has a slot 23. The plug 24 is fixedly connected to the jaw 20. The plug 24 is inserted into the slot 23. The slot 23 is a rectangular hole. The plug 24 and the slot 23 are interference fit. By detachably installing the jaw 20 and the mounting base 11, the jaw 20 can be installed by inserting the plug 24 into the slot 23. The bottom of the mounting base 11 also has a mounting groove 25. Without installing the jaw 20, the mounting base 11 can be directly fixed to the cabinet or wall by passing screws through the mounting groove 25. After installing the jaw 20, the detector body 10 can be fixed to the pipe by the snap-fit ​​between the jaw 20 and the pipe. It has a flexible installation method and is less limited by the installation position.

[0042] like Figure 2 and Figure 3 As shown, a pushing structure is provided on one side of the detector body 10 to push the gripper 20 to deform and close.

[0043] The pushing structure includes an abutting rod 30, an upper pull rod 31, and an adjusting screw 32. The upper pull rod 31 is slidably connected to the detector body 10, the abutting rod 30 is fixedly connected to the upper pull rod 31, and the adjusting screw 32 is rotatably connected to the detector body 10 and threadedly connected to the upper pull rod 31. The abutting rod 30 is a cylinder and is tangent to the outer circumferential surface of the gripper 20. A threaded hole is provided at the top of the upper pull rod 31, and the adjusting screw 32 is threadedly connected to the threaded hole of the upper pull rod 31. Two ear plates are provided on the side wall of the detector body 10. The adjusting screw 32 is rotatably connected to one of the ear plates, and the upper pull rod 31 is slidably connected to the other ear plate.

[0044] In this solution, as a supplementary explanation to the above solution, the upper pull rod 31 is a rectangular column, and the ear plate has a limiting groove adapted to the rectangular column. By inserting the upper pull rod 31 into the limiting groove and threadedly connecting it with the adjusting screw 32, rotating the adjusting screw 32 pulls the upper pull rod 31 up, causing the abutment rod 30 to push against the outer circumference of the two grippers 20. The abutment rod 30 is located below the two grippers 20. The upward movement of the abutment rod 30 causes the grippers 20 to deform and close, thereby increasing the squeezing force of the grippers 20 on the anti-slip pad 21, strengthening the adhesion between the anti-slip pad 21 and the pipe, and further improving the limiting effect after installing the detector body 10.

[0045] The working principle of this utility model is as follows: The detector body 10 includes at least a gas sensor and a signal transmitter. The gas sensor and the signal transmitter are electrically connected. The wireless transmitter includes a controller, a buzzer, and a WiFi module. The gas sensor is connected to the controller, and the controller is connected to both the buzzer and the WiFi module. When a gas leak is detected, an alarm is issued, and a notification is sent to the user's smart terminal via the network to prevent the user from missing the alarm and causing danger. This achieves intelligent detection of gas leaks. Of course, a power supply is also required to power the above components. The above technology is known prior art and will not be described in detail here.

[0046] Two grippers 20 are installed at the ends of the two mounting bases 11. Since the two grippers 20 are mirror-distributed, that is, the openings of the two grippers 20 are opposite to each other, and the anti-slip grooves 22 on the inner walls of the two anti-slip pads 21 have opposite thread directions, when the gas pipe is inserted into the anti-slip pad 21, the two grippers 20 apply a squeezing force to the anti-slip pad 21. With the anti-slip grooves 22 having opposite thread directions, the anti-slip pad 21 can form a good contact force with the pipe, suppressing radial and circumferential displacement between the pipe and the anti-slip pad 21, and ensuring the stability of the detector body 10 during installation. The grippers 20 can be installed by inserting the insert block 24 into the slot 23. The bottom of the mounting base 11 also has Without installing the clamps 20, the mounting slot 25 allows the mounting base 11 to be directly fixed to the cabinet or wall using screws passing through it. After installing the clamps 20, the detector body 10 can be fixed to the pipe using the clamps 20 and the pipe, achieving flexible installation. Rotating the adjusting screw 32 pulls up the pull rod 31, causing the abutment rod 30 to push against the outer circumference of the two clamps 20. The abutment rod 30 is located below the two clamps 20. The upward movement of the abutment rod 30 causes the clamps 20 to deform and close, thus increasing the squeezing force of the clamps 20 on the anti-slip pad 21. This strengthens the adhesion between the anti-slip pad 21 and the pipe, further inhibiting the slippage of the anti-slip pad 21 and the pipe.

[0047] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims.
