[0002] The grain storage industry primarily uses phosphine fumigation to kill pests and create a low-oxygen environment for grain storage using nitrogen, thereby ensuring the quality and safety of stored grain. Although many companies are developing products with related functions, most of these products require operators to go to the site to perform gas extraction and testing, which increases the workload of workers. At the same time, phosphine is a colorless, highly toxic, and spontaneously combustible gas. Inhalation of phosphine can affect the heart, respiratory system, kidneys, gastrointestinal tract, nervous system, and liver. Fumigation requires a gas concentration of over 500 pm, which undoubtedly poses a huge safety threat to any on-site operator.
[0003] However, traditional gas detection devices can only detect gas in the air at a fixed location and cannot achieve multi-point and multi-area detection. They have a small detection range and low working efficiency. Most gas detection devices on the market are difficult to adjust the detection range, and users cannot adjust them themselves. Some require manual carrying into the grain warehouse to detect gas.

[0016] The beneficial effects of this invention are: 1. This invention utilizes a contact device that is easily disassembled and usable. When the detection area is large, multiple sets of contact devices can be installed on the track to increase the number of detection points, preventing inconsistent detection results due to large differences in detection distance. Increasing the number of detection points improves detection efficiency, enabling multi-point interval detection, expanding the detection range, and enhancing operational convenience.

[0025] The gas detection device 101 has six sets of threaded holes on its top, and each of the six sets of threaded holes is fitted with a long screw 28. The long screw 28 is threaded into the threaded hole and is removable. A power connection bracket 26 is installed on the right side of the top of the gas detection device 101. The power connection bracket 26 has a strip-shaped groove 34. A power-conducting strip 27 is movably installed in the strip-shaped groove 34. The power-conducting strip 27 is fitted into the strip-shaped groove 34 and is removable.
[0026] Both the contact head 20 and the energizing strip 27 are made of graphene material.
[0027] The inner cavity of track 1 is provided with an H-shaped groove 2. A moving device 401 is installed inside the H-shaped groove 2. The moving device 401 includes rolling supports 8. Two sets of rolling supports 8 are installed inside the H-shaped groove 2. Sliding shafts 10 are fixedly installed on the left and right sides of the two sets of rolling supports 8. Rollers 9 are sleeved on the outside of the sliding shafts 10. The rollers 9 can rotate relative to the sliding shafts 10 and roll with the H-shaped groove 2. A drive motor 11 is fixedly installed on the top of the two sets of rolling supports 8. A drive wheel 12 is installed on the output shaft end of the drive motor 11. The drive wheel 12 rolls with the roller 9. A connecting hole 32 is provided at the bottom of the two sets of rolling supports 8. A fixing device 701 is installed at the bottom of the connecting hole 32. A self-aligning device 301 is installed at the bottom of the rolling supports 8.
[0028] The top of the H-shaped trough 2 is equipped with a negative wire 3, the bottom right side of the H-shaped trough 2 is equipped with a positive wire 4, and the front and rear ends of the track 1 are equipped with connecting devices 501.
[0029] The fixing device 701 includes a fixing frame 5 and a connecting rod 29. The connecting hole 32 is movably installed inside the connecting rod 29. A bushing 31 is sleeved on the outer wall of the connecting rod 29. The connecting rod 29 is rotatable relative to the bushing 31. The fixing frame 5 is fixedly installed at the bottom of the connecting rod 29. A clamping plate 6 is installed on the left side of the fixing frame 5 through a screw 7. The clamping plate 6 is movable relative to the fixing frame 5 and is detachable. A gas detection device 101 is installed in the inner cavity of the fixing frame 5.
[0030] The self-aligning device 301 includes an end cap 21 and a rotating sleeve 33. The rotating sleeve 33 is sleeved on the top of the connecting rod 29 and is fixed to the connecting rod 29 by an inner pin 22. The end cap 21 is sleeved on the outer end of the rotating sleeve 33. A rectangular groove 25 is opened in the inner circle of the end cap 21. An inner pin 22 is installed in the rectangular groove 25. An outer pin 23 is installed through the inner wall of the cavity of the end cap 21. One end of the outer pin 23 is connected to a return spring 24, and the other end of the return spring 24 is connected to the inner pin 22. The end cap 21 is fixedly installed at the bottom of the rolling support 8 by screws 7.
[0031] By adopting the above technical solution, after the track 1 is fixed, the negative line 3 and the positive line 4 are connected, and two sets of moving devices 401 are installed in the H-shaped groove 2. The power is turned on to drive the motor 11 to rotate, which in turn drives the roller 9 to rotate. Because the roller 9 rotates, it drives the rolling support 8 to move. When the moving device 401 moves, the fixed gas detection device 101 may be offset due to the bending part of the track 1. During linear movement, the tension of the self-returning spring 24 makes the gas detection device 101 return to a straight line. Since the bottom of the contact device 201 is in contact with the positive line 4, the track 1 itself... When the gas detector 101 comes into direct contact with the negative electrode 3, the contact device 201 becomes energized. Because the fixing device 701 is made of engineering plastic, it provides insulation without sacrificing structural strength. When the gas detector 101 moves to the point of contact with the contact head 20, the gas detector 101 and the wire-pulling mechanism 35 become energized, and the bag 36 absorbs air. When the gas detector 101 is powered on, the voltage component 223 generates a reverse voltage, driving the microelectromechanical component 112. Under the drive of the microelectromechanical component 112, the vibrating layer 221 begins to contract inwards and outwards, causing the air inside the bag 36 to enter through the air inlet 111. The light-emitting element 105 uses a semiconductor... The components formed by the semiconductor process can be stacked and integrated on the particle sensing area 114 to emit a light beam L; while the particle sensing element 106, formed by the semiconductor process, can be stacked and integrated on the particle sensing area 114 and is spaced apart from the light-emitting element 105 to receive the light spot formed by the light source scattered by the light beam L emitted by the light-emitting element 105 illuminating the gas, thereby detecting gas particles and generating detection data information. The detection data information generated by this particle sensing element 106 is gas particle detection data information. In this embodiment, the gaseous particulate matter detection data information includes one of PM10, PM2.5, and PM1. The gas sensing element 107, which is a semiconductor-manufactured element, can be stacked and integrated on the gas sensing area 115 to detect the passing gas and generate detection data information. The detection data information generated by the gas sensing element 107 is gas detection data information. In this embodiment, the gas is one of formaldehyde, ammonia, carbon monoxide, carbon dioxide, oxygen, and ozone. Alternatively, the detection data information generated by the gas sensing element 107 may also be virus detection data information.The driving chip element 108 is a component formed using a semiconductor process, and internally includes a microprocessor, a battery, and a communicator. Therefore, the driving chip element 108 can be stacked and integrated on the driving element area 116 for electrical connection with the microelectromechanical component 112, the light-emitting element 105, the particle sensing element 106, and the gas sensing element 107. The microprocessor of the driving chip element 108 controls the driving operation of the microelectromechanical component 112, the light-emitting element 105, the particle sensing element 106, and the gas sensing element 107 respectively, and receives the detection data information output by the particle sensing element 106 and the gas sensing element 107 for calculation and output. The battery of the driving chip element 108 provides gas detection. When the device is powered on, the communicator of the driver chip element 108 receives the detection data information output by the microprocessor and transmits it to an external device. The communicator of the driver chip element 108 connects to the external device wirelessly. The driver chip element 108 controls the driving operation of the microelectromechanical component 112, the light-emitting element 105, the particle sensing element 106, and the gas sensing element 107. The microelectromechanical component 112 is actuated to generate gas delivery. The gas is introduced into the flow channel space 222 through the air inlet 111 and then discharged through the air outlet 300. At this time, the gas passes through the light beam L of the light-emitting element 105, which is indirectly scattered by the encapsulation layer to form gas light spots. The particle sensing element 106 receives and detects the gas particles, providing... The microprocessor of the driving chip element 108 performs calculations and outputs detection data on the particle size and concentration of gas particles. The gas sensing element 107 detects the passing gas and generates gas detection data, which is then provided to the microprocessor of the driving chip element 108 for further calculations and output. The communicator of the driving chip element 108 receives the detection data output by the microprocessor and transmits it to an external device for reception and notification. At this point, the gas detection device 101 has completed its operation. Since the electrical mounting bracket 26 on top of the gas detection device 101 limits the detection time, the moving speed of the mobile device 401 can be adjusted. Both the contact head 20 and the conductive strip 27 are made of graphene, effectively reducing friction. When powered on, the return spring 19 inside the contact device 201 allows the contact head 20 to extend and retract automatically when subjected to external force. Because the contact device 201 uses a clamping and fixing method, disassembly and installation are convenient. When the detection range is large, the number of contact devices 201 can be increased. Setting multiple contact devices 201 improves detection efficiency, enabling multi-point range detection, increasing the detection range and ease of operation. This allows the gas detection equipment 101 to achieve automatic, unmanned detection, effectively reducing production costs and labor intensity. It also effectively prevents gas poisoning from manual entry into the grain silo for gas detection. Customizable detection locations effectively prevent undetected areas and also detect areas unsuitable for personnel entry. Example 2
[0032] Based on Example 1, such as Figures 2 to 10 As shown, the connecting device 501 includes a connecting frame 13, which is installed on the outer wall of the track 1. A threaded hole is provided on the top of the connecting frame 13, and a screw 7 is movably installed in the threaded hole. The screw 7 is threadedly engaged with the threaded hole and is detachable. An interface fixing plate 14 is provided at the bottom of the screw 7. The interface fixing plate 14 is detachable and has anti-slip texture on its bottom surface.
[0033] The top of the H-shaped trough 2 is equipped with a negative wire 3, the bottom right side of the H-shaped trough 2 is equipped with a positive wire 4, and the front and rear ends of the track 1 are equipped with connecting devices 501.
[0034] By adopting the above technical solution, this invention designs the length and shape according to the usage space. The connecting device 501 can connect rails 1 of different lengths and bends together. Because the connecting device 501 is easy to use, during use, simply fit the connecting bracket 13 onto the outer wall of the rail 1, with the interface fixing plate 14 on top. After fitting, use an Allen wrench to tighten the top screws 7 in sequence to complete the installation. During use, the length and shape of the rail 1 can be adjusted according to the user's allocation of usage space. Figure 9 The display shows the assembly and splicing effect, achieving the preset effect of track 1, which can be improved according to customer needs. Since the preset track 1 saves a lot of design time, it is easy to install and use, improves work efficiency, facilitates future maintenance and management, and allows for quick replacement, reducing later maintenance costs. It also allows users to make reasonable use of workspace. This invention is a modular design, with multiple devices using mechanical connections, which facilitates daily maintenance and use, and allows for quick replacement during maintenance. Due to the modular design, track 1 can be customized and personalized to meet the needs of different customers or markets, and personalized solutions can be provided to customers. Example 3
[0035] Based on Examples 1 and 2, such as Figure 11As shown, a cloth bag 36 is also provided at the lower end of the outer wall of the gas detection device 101. The cloth bag 36 is fixedly connected to the outer wall of the gas detection device 101. A gravity ball 37 is hung at the open end of the cloth bag 36. The open end of the cloth bag 36 is fixedly connected to the pull-wire mechanism 35. The pull-wire mechanism 35 consists of a protective shell 3501, a pull-wire motor 3502, a pull rope 3503, a rope drum 3504, a fixing column 3505, a belt 3506, and a motor gear 3507. The protective shell 3501 is fixedly installed on the outer wall of the gas detection device 101. The side wall of the protective shell 3501 that is in contact with other detection devices 101 is left open. The protective shell 3501 is made of insulating material. The pull-wire motor 3502 is located in the inner cavity of the protective shell 3501, and its bottom surface is connected to the gas detection device 101. The outer wall is fixedly connected, and the fixing post 3505 is set in the inner cavity of the protective shell 3501. Its bottom surface is fixedly connected to the outer wall of the gas detection device 101. The rope drum 3504 is sleeved on the outer wall of the fixing post 3505 and is slidably connected to the gas detection device 101. The top of the rope drum 3504 is designed with a gear. The motor gear 3507 is fixedly set on the top of the pull motor 3502. The top of the motor gear 3507 and the rope drum 3504 are fitted with a belt 3506. The belt 3506 is connected to the pulley of the motor gear 3507 and the rope drum 3504. The top of the pull rope 3503 is wrapped around the surface of the rope drum 3504, connected to the pull motor 3502 and passing through the outer wall of the protective shell 3501. The bottom end of the pull rope 3503 is wrapped around the opening end of the cloth bag 36 and fixedly connected to the cloth bag 36.
[0036] By adopting the above technical solution, when the pull-wire motor 3502 is started, it will drive the motor gear 3507 to rotate, which in turn drives the rope drum 3504 to rotate via the belt 3506. When the rope drum 3504 rotates, the pull rope 3503 will extend / contract with the rotation of the rope drum 3504. If it is contracted, the pull rope 3503 will pull the cloth bag 36 and the gravity ball 37 upward until the outer wall of the cloth bag 36 is in contact with the outer wall of the protective shell 3501 and stops. At this time, the opening end of the cloth bag 36 is pulled to fold and close. If it is extended, the pull rope 3503 will not pull the cloth bag 36 upward. At this time, the gravity ball 37 will be affected by gravity and pull the cloth bag 36 downward. At the same time, the extension of the pull rope 3503 will allow the opening end of the cloth bag to open and absorb air. Example 4
[0037] like Figure 12 As shown, the controller is also electrically connected to the positive and negative wires. The controller is also connected to an external computing device via a 4 / 5G WiFi network. The controller is equipped with a control system for controlling the operation of the positive and negative wires and the wire-pulling mechanism. The control system consists of three main modules: a signal receiving module, a signal analysis module, and a control module. The signal receiving module is connected to the computing device and is used to receive control signals transmitted by the computing device. The signal analysis module is used to analyze the control signal and transmit the analysis results to the control module; It should be noted that when the signal analysis module analyzes the control signal, it will analyze the device corresponding to the control signal and the control state that needs to be performed (for example, the positive line needs to be powered on), and then transmit the analysis results to the control module.
[0038] The control module is used to control the operation of one or more of the positive wire, negative wire, and wire pulling mechanism based on the analysis results.
[0039] It is important to note that after the control module receives the analysis results, it controls one or more of the positive wire, negative wire, and wire pulling mechanism to operate based on the analysis results. This control can interrupt the original operating state. If both the positive and negative wires are energized, and the wire pulling mechanism is also energized when the equipment is running, the auxiliary gas detection equipment will operate normally even without a control signal.
[0040] By adopting the above technical solution, the present invention receives control signals transmitted by the computing device through a signal receiving module and transmits the control signals to a signal analysis module. The signal analysis module receives and analyzes the control signals, and then transmits the analysis results to the control module. After receiving the analysis results, the control module controls the operation of one or more of the positive wire, negative wire, and wire pulling mechanism according to the analysis results.

[0041] like Figure 13 As shown, a computing device is provided with a display screen, which is connected to a controller via a 4 / 5G WiFi network. The display screen is used to show the start and stop status of the positive wire, negative wire, and wire pulling mechanism. The start and stop status of the positive wire, negative wire, and wire pulling mechanism can be adjusted by manual touch control of the display screen. After receiving the control signal from the human, the computing device sends a control signal to the control system. The computing device includes a storage device, a processor, and a computing device program stored in the storage device and executable on the processor. When the processor executes the computing device program, it implements the above-mentioned multi-point insertion type in-warehouse gas detection device for large grain silos.
[0042] It should be noted that the display screen will show the operating status (i.e., start / stop status) of the positive wire, negative wire, and wire pulling mechanism. Operators can control the start and stop of the positive wire, negative wire, and wire pulling mechanism through the display screen. During control, the computing device transmits the control information to the controller, and the controller then controls the operation.
