Technical Field
[0001] This invention relates to the field of fire extinguishing device technology, specifically to a rail-mounted intelligent mobile fire extinguishing device for warehouse spaces. Background Technology
[0002] In the field of fire safety in warehouse spaces, existing fire extinguishing devices have many shortcomings. Traditional fire extinguishing devices often require manual clearing of tracks or obstacle avoidance for track passage, making it difficult for them to autonomously cross common debris and resulting in poor reliability. In terms of fire extinguishing effectiveness, the fire extinguishing capacity is limited due to large water pressure loss at long distances, and additional high-pressure pumps or energy storage devices are usually required to ensure water pressure. The functional modes lack adaptive capabilities and cannot be flexibly switched according to actual water pressure, resulting in unnecessary mechanical wear at close range and poor fire extinguishing effect at long distances. The devices have low integration, many parts, complex assembly, and many points of failure. At the same time, the positioning and monitoring capabilities are limited, making it difficult to accurately identify the fire source and judge the fire intensity. They are easily affected by non-fire heat sources, and it is difficult to effectively assess the effect and prevent reignition after the fire is extinguished. Existing fire extinguishing systems may require manual clearing of tracks or avoidance of obstacles and cannot autonomously traverse common debris, resulting in poor reliability of passage in real warehouse sites.
[0003] To address the above issues, a rail-mounted intelligent mobile fire extinguishing device for warehouse spaces is proposed. Summary of the Invention
[0004] The purpose of this invention is to provide a rail-mounted intelligent mobile fire extinguishing device for warehouse spaces. By using this device, the problem of existing fire extinguishing devices in the above-mentioned background, which may require manual clearing of the track or avoidance of obstacles and cannot autonomously cross common debris, resulting in poor reliability of passage in real warehouse sites, is solved.
[0005] To achieve the above objectives, the present invention provides the following technical solution: A rail-mounted intelligent mobile fire extinguishing device for warehouse spaces is provided, comprising a rail fixed within the warehouse space, hydraulic rods on both sides of the rail, a tilting motor at the upper end of the hydraulic rod, the output end of which is connected to a Y-shaped rod assembly, the other end of which is rotatably connected to several drive wheel assemblies arranged along the rail, a diffuse reflection photoelectric sensor on the Y-shaped rod assembly, and a fire accessory box connected to the lower end of the hydraulic rods. The fire accessory box has a positioning system at the upper end and a thermal imager, a telescopic nozzle assembly, and an angle adjustment assembly at the lower end. Inside the fire accessory box is a double-cone reversing pipe assembly, whose diameter gradually increases from the middle to both ends. The left end is connected to a switching drive assembly, and the inner part is rotatably connected to a Z-shaped isolation plate assembly, which divides the fire accessory box into upper and lower chambers with symmetrical water inlets in the middle. The device has an outlet and an inlet connected to a water source. The outlet is connected to a telescopic nozzle assembly. The Z-shaped isolation plate assembly has two isolation and pressurization components on each of its upper and lower sides.

Based on feedback from the pressure sensor, the device can switch between short-range and long-range modes to achieve functions such as automatic pressurization, squeezed water discharge, air-water mixed jet, and drive wheel assembly locking.
[0006] Furthermore, the double-cone reversing pipe assembly includes a straight pipe, with tapered pipes at both ends of the straight pipe. The smaller diameter ends of the two tapered pipes are fixedly connected to and communicate with the two ends of the straight pipe, respectively. The larger diameter ends of the two tapered pipes are fixedly connected to two isolation covers, respectively. A water inlet and a water outlet are respectively provided on the upper and lower sides of the middle position of the straight pipe. An air outlet and an air inlet are respectively provided on the upper and lower sides of the two tapered pipes. The air outlet and the air inlet communicate with the air outlet chamber and the air inlet chamber, respectively. The air outlet is fixedly connected to and communicates with the second solenoid valve.
[0007] Furthermore, the switching drive assembly includes a switching motor, which is fixedly connected to one of the isolation covers. The switching motor and the isolation cover are coaxially arranged, and the output end of the switching motor is fixedly connected to a rotating shaft, which is rotatably connected to the isolation cover.
[0008] Furthermore, the Z-shaped isolation plate assembly includes an axial connecting plate, on which a first solenoid valve is fixedly connected. The axial connecting plate is disposed within a sealed cavity formed by the tapered tube, the straight tube, and the inner cavity of the isolation cover. The axial connecting plate is tightly attached to the inner wall of the sealed cavity. Two semi-circular partitions are fixedly connected to both ends of the axial connecting plate. The two semi-circular partitions are symmetrically arranged at the center. The semi-circular partitions are fixedly connected to the rotating shaft. The cross-section of the axial connecting plate and the two semi-circular partitions is approximately Z-shaped. The axial connecting plate and the two semi-circular partitions divide the double-tapered reversing tube assembly into upper and lower cavities.
[0009] Furthermore, the isolation and pressurization assembly includes a cylinder, which is fixedly connected to an axial connecting plate. A semi-circular extrusion plate is fixedly connected to the output end of the cylinder, and the semi-circular extrusion plate is in close contact with the inner walls of the upper and lower cavities.
[0010] Furthermore, the telescopic nozzle assembly includes a telescopic atomizing nozzle, and a gas nozzle is fixedly connected to the telescopic atomizing nozzle.
[0011] Furthermore, the angle adjustment component includes an adjustment motor, which is fixedly connected to the bottom of the fire-fighting accessory box. A bevel gear one is fixedly connected to the output end of the adjustment motor. A drive shaft is fixedly connected to the telescopic atomizing nozzle. The drive shaft is rotatably connected to the fire-fighting accessory box. A bevel gear two is fixedly connected to the drive shaft. The bevel gear one meshes with the bevel gear two.
[0012] Furthermore, the Y-shaped rod assembly includes a connecting shaft, which is rotatably connected to a hydraulic rod. One end of the connecting shaft is fixedly connected to the output end of a tilting motor. A first roller is rotatably connected to the connecting shaft, and the first roller is in close contact with the hanging rail. A longitudinal connecting rod is fixedly connected to the other end of the connecting shaft. The drive wheel assembly includes a rotating tube, and two rotating tubes are rotatably connected to the longitudinal connecting rod. A second roller is fixedly connected to the rotating tube, and the second roller is in close contact with the hanging rail.
[0013] Furthermore, the pneumatic locking assembly includes a piston slidably connected inside a rotating tube. The rotating tube is connected to a second solenoid valve via a flexible hose. The piston is fixedly connected to a conical block. A return spring is installed inside the rotating tube. One end of the return spring is fixedly connected to the rotating tube, and the other end is fixedly connected to the conical block. A locking rod is radially slidably connected to the rotating tube. One end of the locking rod abuts against the conical block. A pressure-bearing spring is sleeved on the locking rod. A locking ring is fixedly connected to the longitudinal connecting rod, and the locking ring has several locking holes.
[0014] Compared with the prior art, the beneficial effects of the present invention are as follows: 1. The diffuse reflection photoelectric sensor monitors the status of the drive wheel assembly in the forward direction in real time. Once an obstacle is detected, the controller starts the flip motor, which drives the Y-shaped rod assembly to rotate, causing the rear drive wheel assembly to flip over to the front. This is equivalent to jumping over the obstacle on the track. This design allows the fire extinguishing device to autonomously cross common debris without the need for manual track clearing or obstacle avoidance, further improving the reliability of passage in real warehouse sites. 2. By utilizing the compressed gas in the air outlet chamber, during the water storage process of long-distance fire extinguishing, the volume of the air outlet chamber decreases to generate high-pressure gas. This gas is switched to the pneumatic locking assembly via the second solenoid valve, which directly locks the drive wheel assembly. This converts the byproducts of the fire extinguishing process into obstacle-crossing auxiliary power, which simplifies the structure and improves the reliability of obstacle-crossing actions. 3. By combining the double-cone reversing tube assembly and the Z-type isolation plate assembly, mechanical automatic pressure storage and squeezing water discharge are realized. During the water storage and squeezing cycle, the device simultaneously realizes the synchronous action of air intake in the air inlet chamber and air exhaust in the air outlet chamber. When the water in the hydraulic chamber is squeezed out, the original air inlet chamber rotates to the top, and the gas that is drawn in is sprayed out from the telescopic nozzle assembly through the second solenoid valve and hose, directly acting on the mist water. This air-water mixed jet can significantly enhance the water penetration, expand the coverage area, and improve the cooling and suffocation effect. At the same time, the gas jet can also be used to disperse the smoke above the fire source and assist the thermal imager in accurate positioning. 4. The controller flexibly switches between two modes based on the pressure sensor's judgment. In short-range mode, the first solenoid valve opens, connecting the water storage chamber and the hydraulic chamber, allowing water to flow directly through. Simultaneously, the pressure boosting components are brought closer together to narrow the flow path and stabilize the flow rate, achieving low-loss, high-efficiency direct supply. In long-range mode, the first solenoid valve closes, initiating the pressure storage and compression cycle, and the switching drive components continue to operate, achieving intermittent pressure boosting water supply. This adaptive mode switching avoids unnecessary mechanical losses at close range and ensures effective fire extinguishing at long distances. Attached Figure Description

[0017] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0018] A rail-mounted intelligent mobile fire extinguishing device for warehouse spaces, referring to Figures 1-8As shown, it includes a hanging rail 1 fixed in the storage space, hydraulic rods 2 on both sides of the hanging rail 1, a flip motor 3 at the upper end of the hydraulic rod 2, the output end of which is connected to a Y-shaped rod assembly 4, the other end of the Y-shaped rod assembly 4 is rotatably connected to several drive wheel assemblies 5 arranged along the hanging rail 1, the Y-shaped rod assembly 4 has a diffuse reflection type photoelectric sensor 6, the lower end of the hydraulic rod 2 is connected to a fire accessory box 7, the upper end of the fire accessory box 7 has a positioning system 9, the lower end has a thermal imager 10, a telescopic sprinkler assembly 20 and an angle adjustment assembly 30, the fire accessory box 7 has a double cone reversing pipe assembly 40, the diameter of which gradually increases from the middle to both ends, the left end is connected to a switching drive assembly 50, and the inside is rotatably connected to a Z-shaped isolation plate assembly 60; The Z-shaped isolation plate assembly 60 divides the space into upper and lower cavities, with symmetrical water inlets 401 and outlets 402 in the middle. Water inlets 401 connect to a water source, and outlets 402 connect to a telescopic nozzle assembly 20. The Z-shaped isolation plate assembly 60 has two isolation and pressurization assemblies 70 on each of its upper and lower sides. The upper side forms an air outlet chamber 701 and a water storage chamber 703, while the lower side forms an air inlet chamber 705 and a hydraulic chamber 706. The Z-shaped isolation plate assembly 60 has a first solenoid valve 601, and the water inlet 401 has a pressure sensor 403. The Y-shaped rod assembly 4 has a pneumatic locking assembly 80 that is connected to the second solenoid valve 702. The device moves via the drive wheel assembly 5, the diffuse reflection photoelectric sensor 6 monitors obstacles, the flip motor 3 drives the Y-shaped rod assembly 4 to make the drive wheel assembly 5 pass over obstacles, the thermal imager 10 identifies the fire source, the positioning system 9 navigates, and the device can switch between short-range and long-range modes based on the feedback from the pressure sensor 403, realizing functions such as automatic pressure storage, squeezing out water, air-water mixed jet, and locking the drive wheel assembly 5.
[0019] This configuration allows several drive wheel assemblies 5 to roll on the hanging rail 1. That is, when the drive wheel assembly 5 is displaced relative to the hanging rail 1, the rolling of the drive wheel assembly 5 on the hanging rail 1 is existing technology and is not shown in the figure. The movement of the drive wheel assembly 5 drives the Y-shaped rod assembly 4 to move synchronously, which in turn drives the flipping motor 3 and the hydraulic rod 2 to move synchronously. When the diffuse reflection photoelectric sensor 6 detects that the drive wheel assembly 5 located in front of the forward direction is blocked by a packaging bag or other debris and cannot continue to move forward, the diffuse reflection photoelectric sensor 6 transmits the monitoring result to the controller. The controller is existing technology and is not shown in the figure. After receiving the monitoring information, the controller controls the flipping motor 3 to rotate, which in turn drives the Y-shaped rod assembly 4 to rotate synchronously. When the Y-shaped rod assembly 4 rotates, it causes the drive wheel assembly 5 originally located behind the forward direction to flip, so that it flips to the front of the drive wheel assembly 5 originally located in front of the forward direction. After that, the flipping motor 3 continues to work, causing the drive wheel assembly 5 originally located in front of the forward direction to return to the front of the forward direction. At this time, the flipping motor 3 stops working. In this way, the drive wheel assemblies 5 in front and behind the forward direction can overcome the obstruction by flipping. The diffuse reflection photoelectric sensor 6 monitors the status of the forward drive wheel assembly 5 in real time. Once an obstacle is detected, the controller activates the flip motor 3, which rotates the Y-shaped rod assembly 4, causing the rear drive wheel assembly 5 to flip over to the front. This is equivalent to jumping over obstacles on the track. This design allows the fire extinguishing device to autonomously cross common debris without manual track clearing or obstacle avoidance, further improving its reliability in real warehouse environments. The thermal imager 10 identifies the location and three-dimensional coordinates of the fire source within the warehouse space, determines the stage of fire development, filters out non-fire heat sources to reduce false alarms, and monitors temperature changes in real time after fire extinguishing. After fire extinguishing, the effectiveness is evaluated to prevent reignition. The positioning system 9 provides the device with real-time, high-precision spatial position information, enabling navigation of the drive wheel assembly 5 on the rail 1, precise arrival at the fire source, motion control, and multi-machine collaborative scheduling. It also supports automatic return. This technology is existing. When the device moves above the fire source via the drive wheel assembly 5, the telescopic nozzle assembly 20 extends. The extension and retraction of the telescopic nozzle assembly 20 is existing technology. Simultaneously, the angle adjustment assembly 30 activates, causing the telescopic nozzle assembly 20 to deflect downwards through transmission, so that the telescopic nozzle assembly 20 faces the fire source. At this point, the angle adjustment assembly 30 stops working and locks. After the fire is extinguished, the angle adjustment assembly 30 restarts and reverses its operation, causing the extension and retraction... The nozzle assembly 20 deflects in the opposite direction, and simultaneously the telescopic nozzle assembly 20 retracts. Water flows through the hose from the inlet 401 into the inner cavity of the double-cone reversing pipe assembly 40. During fire extinguishing, when the fire source is far from the device, the device needs to move to the target location to extinguish the fire, which lengthens the water delivery distance. This results in greater water pressure loss during water delivery, leading to poor fire extinguishing effect. Therefore, when the pressure sensor 403 detects low water pressure at the inlet 401, the pressure sensor 403 transmits the monitoring information to the controller. The controller then controls the first solenoid valve 601 to close. At this time, the water storage chamber 703 and the hydraulic chamber 706 are isolated. The two valves located on both sides of the inlet 401... The isolation and pressurization components 70 quickly move away from each other, causing the water storage chamber 703 to store water. At the same time, the switching drive component 50 rotates, which in turn drives the Z-shaped isolation plate component 60, the first solenoid valve 601, and the isolation and pressurization components 70 to rotate synchronously. When the original water storage chamber 703 rotates to the position corresponding to the water outlet 402, the water storage is completed. At this time, the water is squeezed out from the water outlet 402 by the squeezing action of the two isolation and pressurization components 70, avoiding poor fire extinguishing effect due to low hydraulic pressure. At the same time, the original hydraulic chamber 706 rotates to the original position of the water storage chamber 703. During this process, the two isolation and pressurization components 70 originally located on both sides of the water outlet 402 rotate upward and move away from each other to store water. This process is repeated. During the water storage process, the isolation and pressurization components 70 on both sides of the inlet 401 move further apart, causing the volume of the air outlet 701 to decrease. At the same time, during the process of squeezing out the water in the hydraulic chamber 706 for fire extinguishing, the volume of the air inlet 705 increases to draw in air. When the water in the hydraulic chamber 706 is squeezed out, the volume of the air inlet 705 reaches its maximum and the volume of the air outlet 701 reaches its minimum. Then, the switching drive component 50 continues to rotate, causing the original air inlet 705 to rotate upward to press out the gas. The pressed-out gas is sprayed out from the telescopic nozzle assembly 20 through the hose and sprayed towards the mist water sprayed from the telescopic nozzle assembly 20. The original air outlet 701 rotates downward to draw out air. When the fire source is close enough not to affect the fire extinguishing effect, the first solenoid valve 601 opens. At this time, the water storage chamber 703 is connected to the hydraulic chamber 706, and water can flow in from the inlet 401, pass through the first solenoid valve 601 and flow out from the outlet 402, and then spray out from the telescopic nozzle assembly 20 to extinguish the fire. At this time, the switching drive assembly 50 stops working, and the isolation pressurization assemblies 70 on the upper and lower sides of the Z-shaped isolation plate assembly 60 move closer to each other to reduce the water flow channel, thereby achieving the effect of stabilizing the water flow speed. When the diffuse reflection photoelectric sensor 6 detects that the forward drive wheel assembly 5 is blocked by an obstacle, the second solenoid valve 702 switches. At this time, the air pressure locking assembly 80 is connected to the air outlet chamber 701, and the isolation pressurization assemblies 70 on both sides of the inlet 401 move further apart, making the volume of the air outlet chamber 701 smaller, thereby increasing the air pressure of the air pressure locking assembly 80, thereby locking the drive wheel assembly 5, and then the drive wheel assembly 5 is flipped. By combining the double-cone reversing pipe assembly 40 and the Z-shaped isolation plate assembly 60, mechanical automatic pressure storage and squeezing water discharge are achieved. When the pressure sensor 403 detects that the water pressure at the inlet 401 is too low, the first solenoid valve 601 closes, and the isolation booster assembly 70 quickly moves away to form the water storage chamber 703. Then, the switching drive assembly 50 rotates the water storage chamber 703 to the position of the outlet 402. The water is forcefully discharged by the squeezing action of the isolation booster assembly 70. This design ensures that the device can still maintain sufficient water pressure when extinguishing fires at a distance, and does not require an additional high-pressure pump or energy storage device, which significantly improves the reliability and adaptability of fire extinguishing. During the cycle of water storage and compression, the device simultaneously achieves the synchronous action of air intake in air chamber 705 and air exhaust in air outlet chamber 701. When the water in hydraulic chamber 706 is squeezed out, the original air intake chamber 705 rotates to the top, and the gas that was drawn in is sprayed out from telescopic nozzle assembly 20 through second solenoid valve 702 and hose, directly acting on the mist water. This air-water mixed jet can significantly enhance the water's penetration, expand the coverage area, and improve the cooling and suffocation effect. At the same time, the gas jet can also be used to disperse the smoke above the fire source and assist the thermal imager 10 in accurate positioning. The controller uses pressure sensor 403 to determine the pressure and flexibly switch between two modes: In short-range mode: the first solenoid valve 601 is opened, the water storage chamber 703 is connected to the hydraulic chamber 706, and water passes directly through. At the same time, the isolation booster components 70 are brought close to each other to narrow the flow channel and stabilize the flow rate, so as to achieve low loss and high efficiency direct supply. Remote mode: Close the first solenoid valve 601, start the pressure storage and squeezing cycle, and switch the drive component 50 to work continuously to achieve intermittent pressurized water supply. This adaptive mode switching avoids unnecessary mechanical wear at close range and also ensures the fire extinguishing effect at long distance. This device cleverly utilizes the compressed gas in the air outlet chamber 701. During the water storage process for long-distance fire extinguishing, the volume of the air outlet chamber 701 decreases, generating high-pressure gas. This gas is switched to the pneumatic locking assembly 80 via the second solenoid valve 702, which directly locks the drive wheel assembly 5. This design transforms the byproducts of the fire extinguishing process into obstacle-crossing auxiliary power, which simplifies the structure and improves the reliability of obstacle-crossing actions. All core functions are integrated into the double conical reversing pipe assembly 40. One pipe can simultaneously perform multiple functions such as water pressure regulation, air path switching, water storage and squeezing, gas compression or release. The rotation of the Z-type isolation plate assembly 60 and the isolation booster assembly 70 is controlled by a single switching drive assembly 50. All logic can be completed with the help of two solenoid valves. This electromechanical-hydraulic-pneumatic integrated design greatly reduces the number of parts, reduces assembly complexity and potential failure points.
[0020] Reference Figure 5 and Figure 6 As shown, the double-cone reversing pipe assembly 40 includes a straight pipe 404, with tapered pipes 405 at both ends of the straight pipe 404. The smaller diameter ends of the two tapered pipes 405 are fixedly connected to and communicate with the two ends of the straight pipe 404, respectively, and the larger diameter ends of the two tapered pipes 405 are fixedly connected to two isolation covers 406. This design makes the inner cavities of the tapered pipes 405, the straight pipe 404, and the isolation covers 406 form a sealed cavity. The upper and lower sides of the middle position of the straight pipe 404 are respectively provided with a water inlet 401 and a water outlet 402. The upper and lower sides of the two tapered pipes 405 are respectively provided with an air outlet 407 and an air inlet 408. The air outlet 407 and the air inlet 408 are respectively connected to the air outlet cavity 701 and the air inlet cavity 705. The air outlet 407 is fixedly connected to and communicates with the second solenoid valve 702.
[0021] The switching drive assembly 50 includes a switching motor 501, which is fixedly connected to an isolation cover 406. The switching motor 501 and the isolation cover 406 are coaxially arranged. The output end of the switching motor 501 is fixedly connected to a rotating shaft 502, and the rotating shaft 502 is rotatably connected to the isolation cover 406.
[0022] The Z-type isolation plate assembly 60 includes an axial connecting plate 602. A first solenoid valve 601 is fixedly connected to the axial center of the axial connecting plate 602. The axial connecting plate 602 is disposed in a sealed cavity formed by the tapered tube 405, the straight tube 404, and the inner cavity of the isolation cover 406. The axial connecting plate 602 is in close contact with the inner wall of the sealed cavity. Two semi-circular partitions 603 are fixedly connected to both ends of the axial connecting plate 602. The two semi-circular partitions 603 are centrally symmetrically arranged. The semi-circular partitions 603 are fixedly connected to the rotating shaft 502. The cross-section of the axial connecting plate 602 and the two semi-circular partitions 603 is approximately Z-shaped. The axial connecting plate 602 and the two semi-circular partitions 603 divide the double tapered reversing tube assembly 40 into upper and lower cavities.
[0023] The isolation pressurization assembly 70 includes a cylinder 707, which is fixedly connected to the axial connecting plate 602. A semi-circular extrusion plate 708 is fixedly connected to the output end of the cylinder 707. The semi-circular extrusion plate 708 is tightly attached to the inner walls of the upper and lower cavities. During fire extinguishing, when the pressure sensor 403 detects low water pressure and poor fire extinguishing effect, the first solenoid valve 601 closes, allowing water to enter the water storage chamber 703. Simultaneously, the cylinder 707 located above the axial connecting plate 602 contracts, causing the water storage chamber 703 to gradually increase in size for water storage. At the same time, the volumes of the two air outlet chambers 701 located above the axial connecting plate 602 decrease, allowing gas in the air outlet chambers 701 to flow out through the second solenoid valve 702 and be ejected from the telescopic nozzle assembly 20. Simultaneously, the cylinder 707 located below the axial connecting plate 602 extends, thereby causing the air outlet chamber 701 located below the axial connecting plate 602 to extend. The lower semi-circular extrusion plates 708 move closer together, reducing the volume of the hydraulic chamber 706 and squeezing out water. The squeezed water passes through the outlet 402 and enters the telescopic nozzle assembly 20 through a hose, then sprays out from the telescopic nozzle assembly 20 to extinguish the fire. When the volume of the hydraulic chamber 706 reaches its minimum, the switching motor 501 starts, driving the rotating shaft 502 to rotate, which in turn drives the axial connecting plate 602, the semi-circular partition 603, the cylinder 707, and the semi-circular extrusion plates 708 to rotate synchronously. This causes the two semi-circular extrusion plates 708, which were originally located above the axial connecting plate 602, to rotate 180 degrees, thus transferring the water that has been stored to the position corresponding to the outlet 402. Then, the cylinder 707 extends, squeezing out the water again to extinguish the fire. This process is repeated. In summary, the telescopic nozzle assembly 20 sprays water and air simultaneously.
[0024] The telescopic nozzle assembly 20 includes a telescopic atomizing nozzle 201. Water flowing from the outlet 402 enters the telescopic atomizing nozzle 201 through a hose and is then sprayed out from the telescopic atomizing nozzle 201. A gas nozzle 202 is fixedly connected to the telescopic atomizing nozzle 201. Gas squeezed from the air outlet 701 flows out through the second solenoid valve 702, then enters the gas nozzle 202 through a hose and is then sprayed out from the gas nozzle 202.
[0025] Reference Figure 4 As shown, the angle adjustment assembly 30 includes an adjustment motor 301, which is fixedly connected to the bottom of the fire accessory box 7. A bevel gear 302 is fixedly connected to the output end of the adjustment motor 301. A drive shaft 303 is fixedly connected to the telescopic atomizing nozzle 201. The drive shaft 303 is rotatably connected to the fire accessory box 7. A bevel gear 304 is fixedly connected to the drive shaft 303. The bevel gear 302 and the bevel gear 304 mesh. When the device is moved above the fire source, the adjustment motor 301 is started, causing the motor to drive the bevel gear 302 to rotate. This causes the bevel gear 304 to drive the drive shaft 303 and the telescopic atomizing nozzle 201 to rotate synchronously, so that the telescopic atomizing nozzle 201 faces the fire source.
[0026] Reference Figure 9 and Figure 10 As shown, the Y-shaped rod assembly 4 includes a connecting shaft 41, which is rotatably connected to the hydraulic rod 2. One end of the connecting shaft 41 is fixedly connected to the output end of the tilting motor 3. A roller 42 is rotatably connected to the connecting shaft 41, and the roller 42 is in close contact with the hanging rail 1. A longitudinal connecting rod 43 is fixedly connected to the other end of the connecting shaft 41. The drive wheel assembly 5 includes a rotating tube 51, and two rotating tubes 51 are rotatably connected to the longitudinal connecting rod 43. A roller 52 is fixedly connected to the rotating tube 51, and the roller 52 is in close contact with the hanging rail 1. This arrangement allows the roller 42 and the roller 52 to rotate on the longitudinal connecting rod 43 when they roll on the hanging rail 1. When the diffuse reflection photoelectric sensor 6 detects that roller 42 or roller 52 is blocked by a packaging bag or other debris, the controller controls the flipping motor 3 to rotate counterclockwise. Under the blocking action of the hanging rail 1, the connecting shaft 41, the longitudinal connecting rod 43 and the rotating tube 51 on the right side are rotated counterclockwise, which in turn drives roller 52, which is fixedly connected to the rotating tube 51, to rotate counterclockwise, so that the rear roller 52 can pass over the obstacle. Then the flipping motor 3 continues to rotate counterclockwise, so that the other roller 52 can also pass over the obstacle.
[0027] The pneumatic locking assembly 80 includes a piston 801, which is slidably connected inside the rotating tube 51. The rotating tube 51 is connected to the second solenoid valve 702 via a hose. When the flip motor 3 rotates, the second solenoid valve 702 switches, so that the air outlet chamber 701 is connected to the rotating tube 51. At this time, the cylinder 707 contracts, so that the volume of the air outlet chamber 701 decreases, thereby squeezing the gas into the rotating tube 51, which in turn squeezes the piston 801, causing the piston 801 to slide inside the rotating tube 51. The piston 801 is fixedly connected to the conical block 802. A return spring 803 is installed inside the rotating tube 51. One end of the return spring 803 is fixedly connected to the rotating tube 51, and the other end is fixedly connected to the conical block 802. When the piston 801 moves, it drives the conical block 802 to move synchronously, which compresses the return spring 803. A locking rod 804 is radially slidably connected to the rotating tube 51. One end of the locking rod 804 abuts against the conical block 802. When the conical block 802 moves, it causes the locking rod 804 to move away from the axis. A pressure spring 805 is sleeved on the locking rod 804, which stretches the pressure spring 805. A locking ring 806 is fixedly connected to the longitudinal connecting rod 43. Several locking holes 807 are opened on the locking ring 806. When the locking rod 804 moves away from the axis, it inserts into the locking holes 807, thereby locking the rotating tube 51 and stopping the rotation of the roller 2 52.
