Description

Technical Field

[0001] The invention belongs to the technical field of fire protection engineering, and in particular relates to a fire extinguishing ball projecting device based on a compound bow. Background Art

[0002] As urbanization accelerates, the importance of fire safety issues has become increasingly prominent. This is due to the direct threat of frequent fires with disastrous consequences, as well as the substantial increase in building and population density, which has further exacerbated the risk of fire. The dual improvement of scientific and technological progress and public safety awareness has significantly enhanced the fire safety of new buildings and their facilities. From fire doors, smoke exhaust fans to fire pools and water pump systems, a variety of fire protection facilities have jointly built a strict fire safety network. These facilities strictly follow relevant standards in every link of design, construction and acceptance to ensure their solidity and reliability.

[0003] However, the fire safety progress of new buildings has not been fully covered. Some old residential areas have become a major hidden danger to residents' safety due to the lack of facilities, especially the lack of basic fire-fighting equipment. At the same time, some property companies have obvious omissions in the management and maintenance of fire-fighting facilities, resulting in equipment damage, idleness or failure, further weakening the fire safety line of defense. These problems not only greatly reduce the reliability of fire-fighting facilities, but also seriously shake the public's trust in fire safety.

[0004] With the general improvement of safety awareness, people's expectations for fire-fighting facilities are also constantly upgrading. They are no longer satisfied with basic fire-fighting and evacuation conditions, but are eager for more intelligent and efficient fire-fighting solutions. Therefore, how to maintain and update existing fire-fighting facilities to adapt to higher safety needs has become an urgent issue that needs to be solved.

[0005] In view of the above background, we propose an innovative fire extinguishing ball projecting device. In view of this, we propose a fire extinguishing ball projecting device based on a compound bow. Summary of the invention

[0006] The object of the present invention is to provide a fire extinguishing ball projecting device based on a compound bow to solve the problems raised in the above background technology.

[0007] In view of this, the present invention provides a fire extinguishing ball projecting device based on a compound bow, comprising an automatic controller and further comprising: A launch box, the launch box is located above the automatic controller, and a regulating component for controlling the horizontal and vertical rotation of the launch box is provided on the top of the automatic controller; A rear warehouse, the rear warehouse is fixedly installed at the rear end of the launch box, and a launch port is opened at the front end of the launch box, compound bows are fixedly installed on both sides of the launch box and at the position of the launch port, and the compound bows are connected to cams through bow pieces, and a threading hole is opened on the launch box; A stabilizer, the stabilizer is located in the launch box, the stabilizer is connected to a main string, and the other end of the main string is connected to two auxiliary strings, one end of the two auxiliary strings passes through the threading hole and respectively bypasses two cams to be fixed to the launch box; A power assembly, which is located in the rear compartment and is used to pull the stabilizer to move in the launch box; A storage bin, the storage bin is fixedly mounted on the top of the launch box, a through slot is provided at the bottom of the storage bin near the launch port, and a baffle is connected to the inner wall of the through slot via a return spring hinge; A camera, a rangefinder and anemometer are all fixedly installed at the front end of the storage bin.

[0008] In this technical solution, the control component is set to ensure that the control component is mainly responsible for adjusting the height and horizontal angle of the launch box, as well as the vertical angle. When the launch box is in operation, it can achieve 360° horizontal rotation and lift the launch box to a specified height. When the fire extinguishing ball is consumed, the height can be lowered for replenishment to reduce the risk of human damage. Through the camera, rangefinder and wind speed and direction meter, power component, stabilizer, main string, secondary string, cam, compound bow and bow piece, it is ensured that the control system in the automatic controller controls the stabilizer to move backward in the launch box and pull the main string and secondary string on the cam, compound bow and bow piece into a tight state through the feedback of the camera, rangefinder and wind speed and direction meter. When the fire extinguishing ball enters the launch box through the storage bin and the through slot, the control system in the automatic controller controls the release of the stabilizer, and the tension generated by the main string and secondary string pulls the stabilizer to drive the fire extinguishing ball to hit the specified position through the launch port; the above operation realizes intelligent and automated fire source fire identification and fire extinguishing. It is seamlessly connected with the existing fire alarm system and can be quickly installed without modifying the site. At the same time, the fire protection measures in the area are strengthened at a low cost, the maintenance cost is low and it can be used repeatedly. In addition, the device can also meet the needs of temporary additional fire protection and can be widely used in various scenarios.

[0009] In the above technical solution, further, the regulating component includes: A rotating lifting and lowering rod is arranged on an automatic controller, a hydraulic rod is arranged at the top of the rotating lifting and lowering rod, and the hydraulic rod is connected to the bottom of the launch box through a rotating shaft, and support rods connected to the rotating lifting and lowering rod are rotatably installed on both sides of the launch box.

[0010] In this technical solution, when the launch box is in operation, the rotating lifting rod can achieve 360° horizontal rotation, and the hydraulic rod lifts the launch box to a specified height. The support rod maintains the stable position of the launch box. When the fire extinguishing balls are consumed, the height of the rotating lifting rod can be lowered to replenish them to reduce the risk of human damage. At the same time, two support rods are fixed on both sides of the launch box to ensure its stability.

[0011] In the above technical solution, further, the rotating take-off and landing rod includes: An upper rod and a lower rod, wherein the upper rod is rotatably mounted in the lower rod, and the lower rod is fixed to the automatic controller by a plurality of screws, the hydraulic rod is fixed to the top end of the upper rod by a plurality of screws, one end of the rotating shaft is tightly welded to the top end of the hydraulic rod, the other end of the rotating shaft is tightly welded to the bottom of the launch box, the tail end of the support rod is located on the upper rod, and the tail end of the support rod is tightly welded to the upper rod.

[0012] In this technical solution, when the fire extinguishing balls are consumed, the upper rod can be freely extended and rotated inside the lower rod, the height of the rotating lifting and lowering rod can be lowered for replenishment, and the hydraulic rod can be lifted up and down to adjust the height and angle of the launch box; ensure the structural stability of the lower rod and the automatic controller, and ensure the structural stability of the hydraulic rod, rotating shaft, upper rod, launch box and support rod.

[0013] In the above technical solution, further, the power assembly includes: A winch, the winch is installed in the rear compartment, and a cable connected to the stabilizer is wound around the winch, and a limiter fixed to the inner wall of the launch box is provided on the front side of the winch; Four slide rails, the four slide rails are respectively fixedly installed at the four corners of the inner cavity of the launch box, a stabilizer is provided between the four slide rails, four corners of the stabilizer are fixedly installed with sliders, and the four sliders are respectively slidably installed on the four slide rails, a spherical groove is opened at the front center position of the stabilizer, four holes are opened on the stabilizer, and stabilizing rods fixed to the inner wall of the launch box are slidably installed in the four holes.

[0014] In this technical solution, when the launcher is working, after the angle of the launch box is adjusted by the hydraulic rod, the winch pulls the cable to the appropriate position in the launch box. At this time, the compound bow and the main and auxiliary strings are in a bent and tight state, and the elastic potential energy reaches the set value. Then the limiter on the cable in the winch is released, and the compound bow drives the stabilizer to eject the fire extinguishing ball. When it reaches the launch port, the stabilizer is blocked and stops moving forward, while the fire extinguishing ball flies out smoothly.

[0015] In the above technical solution, further, the slide rail and the launch box are an integrally formed structure, and the slider and the stabilizer are an integrally formed structure.

[0016] In this technical solution, the structural stability of the slide rail and the launch box is ensured, and the structural stability of the slider and the stabilizer is ensured.

[0017] In the above technical solution, further, the winch is fixed to the inner wall of the rear compartment by a plurality of screws, and the outlet cross-section of the launch port is smaller than the cross-sectional size of the stabilizer.

[0018] In this technical solution, the winch structure in the rear compartment is guaranteed to be stable so that the winch can work stably; and the stabilizer is prevented from moving out of the launch port.

[0019] In the above technical solution, further, the diameter of the hole is larger than the diameter of the stabilizing rod, and the hole is slidably connected to the stabilizing rod.

[0020] In this technical solution, it is ensured that when the stabilizer moves in the launch box, the hole can slide on the stabilizer bar, ensuring that the stabilizer bar provides stable support for the stabilizer.

[0021] In the above technical solution, further, the return spring hinge is fixed to the inner wall of the through slot and the baffle plate respectively by a plurality of screws, and the cross-sectional size of the through slot is larger than the cross-sectional size of the baffle plate.

[0022] In this technical solution, after the fire extinguishing ball in the storage bin falls into the launch box through the through slot, the return spring hinge can drive the baffle to automatically rebound to its original position. When the launch port is lower than the rear bin state. At this time, the fire extinguishing ball in the storage bin rolls to the baffle position, pushes the baffle open and falls onto a number of stabilizing rods, and the baffle rotates to the launch port to block the fire extinguishing ball to prevent it from rolling down. At the same time, the remaining fire extinguishing balls in the storage bin are also blocked by the falling fire extinguishing balls. When the pitch angle of the launch box changes again, the fire extinguishing ball in the storage bin rolls to the rear cover and waits for the next launch.

[0023] In the above technical solution, further, the automatic controller, winch, camera, rangefinder and wind speed and direction meter are electrically connected, and the automatic controller, camera, rangefinder and wind speed and direction meter constitute an aiming and measuring system, and the aiming and measuring system is equipped with an AI recognition system.

The camera is equipped with a thermal imaging lens and a wide-angle lens with night vision function, which are responsible for detecting heat sources and thick smoke respectively. When a fire is detected, the launch device aims at the launch position and adjusts the aiming angle in real time through the picture transmitted by the camera. At the same time, the distance data sent back by the rangefinder is used to analyze the elastic force required for launch and guide the winch to pull to the specified distance. The wind speed and direction meter transmits the value to the control system in the automatic controller, and launches the fire extinguishing ball after adjusting to the optimal launch angle according to the wind force; the aiming and measurement system is also equipped with an AI recognition system, which is responsible for processing and analyzing the launch point, obstacle recognition and making adjustments. AI can identify obstacles such as walls and window openings, and select the best launch path to reduce losses. When rescue is necessary, the launch force can be increased to perform destructive rescue operations such as breaking windows. At the same time, the AI ​​system integrates all data to determine the launch posture, and uses methods such as throwing or direct shooting to accurately deliver the fire extinguishing ball to the target area.

[0025] In the above technical solution, further, it also includes: The baffle is rotatably mounted at the rear end of the storage bin In the present technical solution, the baffle is slightly larger than the fire extinguishing ball, so the fire extinguishing ball can be added into the storage bin 11.

[0026] The beneficial effects of the present invention are: 1. The fire-extinguishing ball projector based on the compound bow can automatically search for the fire area through the heat source tracking and smoke recognition functions in the camera, and automatically identify the fire source using AI technology. The rangefinder is responsible for measuring the distance, adjusting the launch method and force according to the obstacles in front of the path, and automatically calculating the pulling force required for the fire-extinguishing ball to be projected. Then, the winch pulls the fire-extinguishing ball to a fixed position and connects the wind speed and direction meter to ensure the accurate landing point of the fire-extinguishing ball.
