Description

Technical Field

[0001] The invention belongs to the technical field of fire extinguishing ball projection, and in particular relates to a fire extinguishing ball projection device. Background Art

[0002] Fire safety has become a focus of people's lives, not only because of the frequency and severity of fires, but also because with the acceleration of urbanization, the density of buildings and population density are increasing. Once a fire occurs, the consequences will be disastrous. In recent years, with the advancement of technology and the improvement of people's safety awareness, the fire safety of new buildings and facilities has been significantly improved.

[0003] Building fire protection facilities include fire doors, fire shutters, fire pools, water tanks, fire pumps, smoke exhaust fans and other equipment, which together constitute the fire safety barrier of the building. These facilities are strictly carried out in accordance with relevant specifications in the design, construction and acceptance stages to ensure their reliability and effectiveness. However, although the fire safety of new buildings and facilities has been guaranteed, the fire protection problems exposed by the lack of responsibility of some old communities and properties cannot be ignored. The fire protection facilities in some old communities are seriously insufficient, and even lack basic fire-fighting equipment, which poses a great threat to the safety of life and property of residents. At the same time, some property companies have serious negligence in the management and maintenance of fire protection facilities, resulting in damage, deactivation or inability to use fire protection facilities normally. These problems not only reduce the reliability of fire protection facilities, but also weaken people's confidence in existing fire protection facilities. In addition, with the improvement of people's safety awareness, higher requirements are also put forward for the reliability and effectiveness of fire protection facilities. People are no longer satisfied with basic fire-fighting equipment and evacuation passages, but hope that fire protection facilities can be more intelligent and efficient. Therefore, the maintenance and updating of fire protection facilities has also become one of the current problems to be solved. In view of this, we propose a fire extinguishing ball projecting device. Summary of the invention

[0004] The object of the present invention is to provide a fire extinguishing ball projecting device to solve the problems raised in the above background technology.

[0005] In view of this, the present invention provides a fire extinguishing ball projecting device, comprising: An automatic controller, wherein the automatic controller is provided with a rotating lifting rod, the top end of the rotating lifting rod is connected to a launch box via a lifter, and two support rods are provided between the rotating lifting rod and the launch box; Four slide rails, the four slide rails are fixedly installed at the four corners of the inner cavity of the launch box, a stabilizer is arranged between the four slide rails, four corners of the stabilizer are fixedly installed with sliders, and the four sliders are slidably installed on the four slide rails, a spherical groove is opened at the front center 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, a bow is arranged on the front side of the stabilizer, strings are connected to both sides of the launch box, and one end of the two strings are wound around the tail end of the bow; A rear bin and a launch port, wherein the rear bin and the launch port are fixedly mounted at the rear end and the front end of the launch box respectively, a 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 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; A camera, a rangefinder and anemometer are fixedly installed at the front end of the storage bin.

[0006] In this technical solution, there are no covers on both sides of the launch box. The bow is made of high-strength and high-elastic material to ensure its range and quality. The tail end of the bow is connected to the stabilizer of the launch box by a string. The four corner sliders of the stabilizer always keep it on the corresponding slide rails, and after the fire extinguishing ball is launched, it is blocked by the protrusions at the four corners of the launch port. The launch port material is firm and thick to prevent damage caused by impact and damage caused by sliding of components. A spherical groove is set in the center of the front end of the stabilizer. When launching, the ball can be attached to the groove to reduce the sliding of the fire extinguishing ball due to irregular shape. The stabilizer is provided with four holes The stabilizer rods are slightly smaller than the holes, parallel to and tangent to the fire extinguishing ball, and support the fire extinguishing ball. The stabilizer rods should be smooth to prevent the fire extinguishing ball from rubbing against the upper and lower covers of the device to generate heat and kinetic energy loss, and further ensure the stability of the fire extinguishing ball during launch. The upper two stabilizer rods are bent to both sides between the launch port and the stabilizer stop position to allow the fire extinguishing ball in the upper storage bin to fall. The rear end of the stabilizer is connected to the winch in the rear bin by a cable, and a cable and a limiter are arranged in front of the winch to keep the cable position in the launch box unchanged.

[0007] When the whole device is working, after the lifting device is rotated to adjust the angle, the winch pulls the cable to the position calculated by the system. At this time, the bow and the string are in a bent and tight state, and the elastic potential energy reaches the set value; the cable limit in the winch is released, the bow drives the stabilizer to eject, and the fire extinguishing ball is ejected under the support of the stabilizer. When it reaches the launch port, the stabilizer is blocked and stops moving forward, and the fire extinguishing ball flies out; When the fire extinguishing ball is launched, the lifter falls, changing the pitch angle of the launch box, so that the launch port is lower than the rear compartment. The fire extinguishing ball in the storage compartment rolls to the baffle position, and relies on its weight to push the baffle open and fall onto the stabilizer bar. Since the baffle rotates to the launch port at the same time to block the fire extinguishing ball, the fire extinguishing ball will not roll down, and the fire extinguishing ball in the storage compartment will also be blocked by the falling fire extinguishing ball. When the launch box is in operation, its pitch angle changes, and the fire extinguishing ball in the storage compartment rolls back to the rear cover. When the winch pulls the stabilizer, the fire extinguishing ball in the launch box moves with the stabilizer under the action of gravity, and the baffle rebounds to its original position.

[0008] In the above technical solution, further, the rotating lifting and lowering rod includes an upper rod and a lower rod, and the bottom end of the upper rod is rotatably installed in the lower rod, and the lower rod is fixed to the automatic controller by a plurality of screws.

[0009] In this technical solution, the rotating lifting and lowering rod is composed of an upper rod and a lower rod. The upper rod extends into the lower rod. The upper rod can freely extend and rotate in the lower rod to ensure the structural stability of the lower rod and the automatic controller.

[0010] In the above technical solution, further, the support rod is rotatably connected to the launch box, the lifter is fixed to the top of the rotating lifting rod by a plurality of screws, and the top of the lifter is rotatably connected to the launch box.

[0011] In this technical solution, the rotating lifting and lowering rod is connected to the launch box through a support rod and a lifter. One end of the support rod is fixed on the rotating lifting and lowering rod, and the other end is connected to the launch box through a rotating shaft. The lifter is fixed to the top of the rotating lifting and lowering rod, and the lifter can be lifted up and down.

[0012] The main function of rotating the lifting and lowering rod is to adjust the height and horizontal angle of the launch box, and the function of the lifter and support rod is to adjust the vertical angle of the launch box.

[0013] When the launch box is in operation, the lifting and lowering rod rotates 360° horizontally, the lifter lifts the launch box to the specified height, and the support rod keeps the launch box shaft connection point in the original position.

[0014] When the fire extinguishing balls are used up, the height of the rotating take-off and landing rod can be lowered to replenish them, maintaining the height of the launch box to reduce human damage. There are two support rods fixed on both sides of the launch box to ensure the stability of the launch box.

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

[0016] In this technical solution, the structural stability of the four slide rails and the launch box is ensured, and the structural stability of the stabilizer and the four sliders is ensured; and the sliders are arranged at the four corners of the stabilizer, so that the sliders can always be kept on the slide rails.

[0017] In the above technical solution, further, the outlet cross-section of the launch port is smaller than the cross-sectional size of the stabilizer, and the diameter of the hole is larger than the diameter of the stabilizer rod.

[0018] In this technical solution, after the fire extinguishing ball is launched, the stabilizer is blocked by the protrusions at the four corners of the launch port. The launch port material is firm and thick to prevent damage caused by impact that may lead to damage to the components due to sliding out. There are four holes on the stabilizer, and each hole passes through a stabilizing rod. The stabilizing rod is slightly smaller than the hole, parallel to and tangent to the fire extinguishing ball, and plays a role in supporting the fire extinguishing ball. The stabilizing rod should be smooth to prevent the fire extinguishing ball from rubbing against the upper and lower covers of the device to generate heat and kinetic energy loss, and further ensure the stability of the fire extinguishing ball when it is launched.

[0019] In the above technical solution, further, the two stabilizing rods have a curved structure at positions directly below the through slots.

[0020] In this technical solution, the two upper stabilizing rods are bent to both sides between the launch port and the stabilizer stop position, so that the fire extinguishing balls in the upper storage bin can fall into the launch box through the through slot.

[0021] In the above technical solution, further, it also includes: A baffle is rotatably mounted at the rear end of the storage bin.

[0022] In the technical solution, the baffle plate arranged on the storage bin is slightly larger than the fire extinguishing ball, so that the fire extinguishing ball can be added into the storage bin.

[0023] 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.

The thermal imaging lens is responsible for detecting heat sources, and the wide-angle lens is responsible for detecting thick smoke. When a fire is detected, the entire device is aimed at the launch position. The control system in the automatic controller adjusts the aiming angle in real time through the camera transmission image, and analyzes the elastic force required for launch through the distance transmitted back by the rangefinder, guiding the winch to pull to the specified distance, and 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.

[0027] In the above technical solution, further, the aiming and measuring system is equipped with an AI recognition system.

[0028] In this technical solution, the aiming and measuring system is equipped with an AI recognition system.

[0038] There are no covers on both sides of the launch box 3. The bow 35 is made of high-strength and high-elastic material to ensure its range and quality. The tail end of the bow 35 is connected to the stabilizer 32 of the launch box 3 by the string 34. The four corner sliders of the stabilizer 32 always keep it on the corresponding slide rail 31, and after the fire extinguishing ball is launched, it is blocked by the protrusions at the four corners of the launch port 36. The material of the launch port 36 is firm and thick to prevent damage caused by the impact and the damage caused by the sliding of the component. A spherical groove is set in the center of the front end of the stabilizer 32, so that the ball can be attached to the groove when launching. In order to reduce the sliding of the fire extinguishing ball due to its irregular shape, the stabilizer 32 is provided with four holes, each hole passes through a stabilizing rod 33, the stabilizing rod 33 is slightly smaller than the hole, the stabilizing rod 33 is parallel to and tangent to the fire extinguishing ball, and plays a role in supporting the fire extinguishing ball. The stabilizing rod 33 should be smooth to prevent the fire extinguishing ball from rubbing against the upper and lower covers of the device to generate heat and kinetic energy loss, and further ensure the stability of the fire extinguishing ball during launch. The upper two stabilizing rods 33 are bent to both sides between the launch port 36 and the stop position of the stabilizer 32, so that the fire extinguishing ball in the upper storage bin 5 falls.

The fire extinguishing ball in the storage compartment 5 rolls to the baffle 52, and relies on its weight to push the baffle 52 open and fall onto the stabilizer bar 33. Since the baffle 52 rotates to the launch port 36 at the same time to block the fire extinguishing ball, the fire extinguishing ball will not roll down, and the fire extinguishing ball in the storage compartment 5 will also be blocked by the falling fire extinguishing ball. When the launch box 3 is in operation, its pitch angle changes, and the fire extinguishing ball in the storage compartment rolls back to the rear cover 51. When the winch 41 pulls the stabilizer 32, the fire extinguishing ball in the launch box 3 moves with the stabilizer 32 under the action of gravity, and the baffle 52 rebounds to its original position.
