Description

Technical Field

[0001] The present application relates to the field of fire-fighting drones, and in particular to a fire-fighting bomb precision launching device. Background Art

[0002] Firefighting drones are usually used for high-rise firefighting. Common firefighting drones include a drone body and a launcher body installed below the drone body. The launcher body includes an inclined material tube, which can accommodate at least two spherical fire bombs. When launching fire bombs, the launcher body launches the fire bombs on the material tube in sequence. After the fire bombs are launched, the drone needs to return to the operation point to refill the fire bombs in the material tube.

[0003] In order to make the drone more flexible when flying, the material tube is usually set shorter so that the downward projection of the drone body can cover the material tube, thereby making the cross-sectional area of ​​the drone as small as possible; since the material tube can accommodate a small number of fire bombs, the drone needs to keep going back and forth to refill the fire bombs during the fire-fighting process, resulting in low fire-fighting efficiency of the fire-fighting drone. Summary of the invention

[0004] In order to improve the fire-fighting efficiency of fire-fighting drones, the present application provides a fire-fighting bomb precision launching device.

[0005] The present application provides a fire-fighting bomb precision launching device adopting the following technical solution: A fire bomb precision launching device is installed on a drone body, comprising a launcher body installed below the drone body, the launcher body comprising a material pipe, a material bin with a door is connected below the drone body, the material bin is far away from the launching port of the material pipe, a connecting pipe is connected to the top of the material bin, the connecting pipe is bent downward in a direction away from the material bin, and the lower end of the connecting pipe is connected to the top of the material pipe away from the discharge port; A plurality of fire bombs are placed in the silo, and a loading assembly is also provided in the silo, which can push the fire bombs into the connecting pipe from top to bottom in sequence; A limiting rod is slidably connected to the side wall of the silo close to the material pipe. The limiting rod penetrates the connecting pipe and is slidably plugged with the connecting pipe. A driving member for controlling the sliding of the limiting rod is also provided on the silo.

[0006] By adopting the above technical solution, the operator opens the door and fills the empty silo with fire bombs. When extinguishing the fire, the material tube is filled with fire bombs. At this time, the driving member causes one end of the limit rod to be inserted into the connecting tube. The limit rod limits the feed port of the connecting tube to prevent the fire bombs in the silo from entering the connecting tube, thereby reducing the accumulation of fire bombs in the connecting tube and reducing the possibility of the fire bombs impacting the connecting tube and causing the connecting tube to deform. As the launcher body works, the fire bombs in the material tube decrease. At this time, the driving member works to move the limit rod outside the connecting tube and control the feeding assembly to transport the fire bombs into the connecting tube. The fire bombs fall into the material tube after passing through the connecting tube, thereby filling the material tube. At this time, the driving member works again to insert the limit rod into the connecting tube to prevent the fire bombs in the silo from entering the connecting tube.

[0007] The above operation is repeated continuously until all the fire bombs in the silo enter the material pipe. Since the silo can store more fire bombs and can automatically transport fire bombs to the material pipe, the frequency of the drone's round trip to refill fire bombs is reduced during fire extinguishing operations, thereby improving the fire extinguishing efficiency of the fire extinguishing drone.

[0008] Optionally, a sliding block is fixedly connected to the side wall of the limiting rod close to the silo, and a sliding groove adapted to the sliding block is opened on the silo. The sliding groove is horizontally arranged, and the sliding block is slidably inserted in the sliding groove.

[0009] By adopting the above technical solution, the sliding block is slidably inserted in the horizontally arranged sliding groove, providing a stable sliding guide for the limit rod. Through the cooperation of the sliding block and the sliding groove, the position of the limit rod can be accurately controlled, which is crucial to ensuring the correct position of the fire bomb in the connecting pipe, thereby ensuring the accuracy and reliability of the launch.

[0010] Optionally, the driving member includes a support plate arranged in the material tube, an L-shaped bracket is connected below the support plate, the bracket is slidably connected to the silo, the bracket can slide along the height direction of the silo, a support spring is connected to the bracket, and the lower end of the support spring is connected to the bottom of the silo; The bracket is connected to a driving plate located below the limit rod, and the silo is rotatably connected to a hinge rod located between the limit rod and the driving plate, the upper end of the hinge rod is inclined in a direction away from the limit rod, the limit rod is slidably connected to the hinge rod and slides along the length direction of the hinge rod, the lower end of the hinge rod is slidably connected to the driving plate and slides along the length direction of the driving plate, and the hinge rod and the driving plate can rotate relatively; When no fire bomb is placed on the support plate, the support plate is positioned on the upper part of the material tube by the support spring.

[0011] By adopting the above technical solution, when a fire bomb falls onto the support plate, the fire bomb pushes the support plate, the bracket and the driving plate to move downward, the movement of the bracket compresses the supporting spring, and the driving plate drives the lower end of the hinged rod to continue to rotate downward, and at the same time, the hinged rod moves along the driving plate, and the upper end of the hinged rod rotates in the direction close to the connecting pipe, and pushes the limit rod to move into the connecting pipe. When the support plate stops moving, one end of the limit rod is inserted into the connecting pipe to prevent the fire bomb in the silo from entering the connecting pipe; as the launcher body works, the fire bomb on the support plate moves in the direction close to the launching end, and when the fire bomb moves to separate from the support plate, the supporting spring restores its deformation and pushes the bracket, the support plate and the driving plate to reset, and at the same time, the driving plate drives the limit rod to move outside the connecting pipe through the hinged rod. When the support spring returns to its initial position, the limit rod moves outside the connecting pipe, and the fire bomb in the silo can enter the connecting pipe.

[0012] Optionally, the support plate is an arc-shaped plate, and the inner diameter of the support plate is consistent with the diameter of the fire bomb.

[0013] By adopting the above technical solution, the support plate can better receive the fire bomb.

[0014] Optionally, a T-shaped mounting block is connected to the bracket, and a mounting groove adapted to the mounting block is opened on the outer wall of the silo. The length direction of the mounting groove is arranged along the height direction of the silo, and the mounting block is slidably inserted in the corresponding mounting groove.

[0015] By adopting the above technical solution, the T-shaped mounting block is slidably inserted into the mounting groove arranged along the height direction of the silo, providing a stable sliding guide for the bracket, so that the bracket and the silo slide together, ensuring the stability and accuracy of the bracket during movement.

[0016] Optionally, a T-shaped connecting block is hinged at the lower end of the hinged rod, a connecting groove adapted to the connecting block is provided on the driving plate, the length direction of the connecting groove is arranged along the length direction of the driving plate, and the connecting block is slidably inserted in the connecting groove; One end of the limit rod close to the hinge rod is connected with a connecting rod. The hinge rod is provided with a connecting hole adapted to the connecting rod. The length direction of the connecting hole is arranged along the length direction of the hinge rod, and the connecting rod is slidably inserted in the connecting hole.

[0017] By adopting the above technical solution, the connecting rod cooperates with the connecting groove, so that the hinged rod can slide along the length direction of the driving plate, and the hinged rod can also rotate relative to the driving plate; the connecting rod cooperates with the connecting hole to make the limit rod and the hinged rod slide and cooperate.

Control the operation of the hydraulic cylinder to move the push plate to the initial position, and when the push plate moves to disengage from the top fire bomb, the loading spring recovers its deformation and pushes the remaining fire bombs upward until the top fire bomb contacts the cavity wall at the top of the cavity, at which time the top fire bomb is aligned with the discharge plate.

[0030] The following is combined with Figure 1-6 This application is described in further detail.

[0031] The present application embodiment discloses a fire-fighting bomb precision launching device. Figure 1 , installed on the drone body 1, including a launcher body 2 installed below the drone body 1, the launcher body 2 includes a material tube 21, one end of the material tube 21 is a launch end; a silo 3 is also installed below the drone body 1, the silo 3 is located at the end of the material tube 21 away from the launch end, the silo 3 has a door, and the door of the silo 3 is locked by a lock.

[0032] Reference Figure 2 and Figure 3The silo 3 has a vertically arranged chamber for accommodating fire bombs. A connecting pipe 31 communicating with the cavity is fixedly connected to the side wall of the silo 3 close to the material pipe 21. The connecting pipe 31 is located above the material pipe 21. One end of the connecting pipe 31 away from the silo 3 is bent downward and communicated with the material pipe 21. The position where the connecting pipe 31 communicates with the material pipe 21 is away from the launching end of the material pipe 21; the position where the connecting pipe 31 communicates with the material pipe 21 is located at the top of the material pipe 21, and the position where the connecting pipe 31 communicates with the material pipe 21 can allow the fire bomb to pass through.

[0033] Reference Figure 3 and Figure 4 A plurality of fire bombs are stacked in the chamber of the silo 3, with one fire bomb in each row. The silo 3 is also provided with a loading assembly 4 for pushing the fire bombs into the connecting pipe 31 one by one from top to bottom; a discharge plate 41 is provided at the top of the silo 3 in the silo 3, and at least two T-shaped sliders 411 are fixedly connected to the upper surface of the discharge plate 41. Strip grooves 32 corresponding to the sliders 411 are provided on the inner top surface of the silo 3. The length direction of the strip grooves 32 is arranged along the axial direction of the connecting pipe 31, and each slider 411 is slidably inserted in the corresponding strip groove 32. The slider 411 cooperates with the slide groove to make the discharge plate 41 and the silo 3 slideably cooperate.

[0034] An extension rod 42 is fixedly connected to the bottom of the side wall of the discharge plate 41 away from the connecting pipe 31. The length direction of the extension rod 42 is consistent with the sliding direction of the discharge plate 41, and the lower surface of the extension rod 42 is flush with the lower surface of the discharge plate 41. The extension rod 42 penetrates the side wall of the silo 3 and is slidably plugged with the silo 3; a hydraulic cylinder 43 is installed on the side wall of the silo 3 away from the connecting pipe 31, and the axial direction of the hydraulic cylinder 43 is consistent with the length direction of the extension rod 42. The telescopic rod of the hydraulic cylinder 43 penetrates the silo 3 and is connected to the discharge plate 41.

[0035] The feeding assembly 4 also includes a push plate 44 that is slidably inserted in the cavity, and all fire bombs are located above the push plate 44. The lower surface of the push plate 44 is fixedly connected to a vertically arranged support rod 45, which passes through the lower surface of the silo 3 and is slidably inserted with the silo 3. The lower end of the support rod 45 is fixedly connected to a matching plate 46 located below the silo 3; the matching plate 46 is fixedly connected to a feeding spring 47 that is sleeved on the support rod 45, and the upper end of the feeding spring 47 is fixed to the lower surface of the silo 3.

[0036] In the initial state, the operator controls the hydraulic cylinder 43 through the remote control, so that the discharge plate 41 is located on the side away from the connecting pipe 31 in the silo 3, and the fire bomb is located on the side of the discharge plate 41 close to the connecting pipe 31. Each fire bomb is located above the push plate 44, so that the push plate 44 is located at the bottom of the silo 3, and the loading spring 47 is in a stretched state. By controlling the movement of the telescopic rod of the hydraulic cylinder 43, the discharge plate 41 can be driven to move back and forth, and the discharge plate 41 moves and pushes the fire bomb to move toward the connecting pipe 31. After passing through the connecting pipe 31, the fire bomb falls into the material pipe 21 for use.

[0037] When the discharge plate 41 moves, the extension rod 42 limits the fire bomb below, so that the push plate 44 and the loading spring 47 can be limited, preventing the loading spring 47 from resetting and pushing the push plate 44 and the fire bomb upward, reducing the fire bomb blocking the discharge plate 41 from resetting. The hydraulic cylinder 43 is controlled to work to move the push plate 44 to the initial position. When the push plate 44 moves to break contact with the top fire bomb, the loading spring 47 recovers its deformation and pushes the remaining fire bombs upward until the top fire bomb contacts the cavity wall at the top of the cavity, at which time the top fire bomb is aligned with the discharge plate 41.

[0038] By repeating the above operation continuously, fire-fighting bombs can be continuously delivered to the material tube 21. Since the silo 3 can store more fire-fighting bombs and can automatically deliver fire-fighting bombs to the material tube 21, the drone body 1 can carry more fire-fighting bombs at a time, reducing the need for the drone body 1 to frequently go back and forth to refill fire-fighting bombs, thereby improving the fire-fighting efficiency of the fire-fighting drone; the silo 3 and the material tube 21 are both located in the downward projection of the drone body 1, so that the cross-sectional area of ​​the drone body 1 remains unchanged, thereby reducing the adverse effects on the flexibility of the drone flight.

[0039] Reference Figure 3 and Figure 5 In order to reduce the accumulation of fire bombs in the connecting pipe 31 and reduce the possibility of the connecting pipe 31 being deformed by the impact of the fire bombs on the connecting pipe 31, a control component 5 for controlling the opening and closing of the feed port of the connecting pipe 31 is also provided on the silo 3; the control component 5 includes a limit rod 51 arranged on the side of the silo 3 close to the connecting pipe 31, and the limit rod 51 is arranged horizontally. Figure 6 A T-shaped sliding block 511 is fixedly connected to the side wall of the limit rod 51 close to the silo 3. A sliding groove 33 adapted to the sliding block 511 is opened on the silo 3. The length direction of the sliding groove 33 is arranged along the radial direction of the connecting pipe 31. The sliding block 511 is slidably inserted in the sliding groove 33. The sliding block 511 cooperates with the sliding groove 33 to make the limit rod 51 and the silo 3 slide together; the limit rod 51 passes through the connecting pipe 31 and can be separated from the connecting pipe 31.

[0040] Reference Figure 5 and Figure 6 The control assembly 5 also includes a driving member 52 for driving the limit rod 51 to move, and the driving member 52 includes a support plate 521 arranged in the material tube 21, the inner diameter of the support plate 521 is consistent with the diameter of the fire bomb, and a groove for accommodating the support plate 521 is also provided on the inner wall of the material tube 21; an L-shaped bracket 522 is fixedly connected to the lower surface of the support plate 521, and the bracket 522 passes through the material tube 21 and is slidably plugged with the material tube 21; a T-shaped mounting block 523 is fixedly connected to the side of the bracket 522 close to the silo 3, and a mounting groove 34 adapted to the mounting block 523 is provided on the silo 3, and the length direction of the mounting groove 34 is arranged along the height direction of the silo 3, and the mounting block 523 cooperates with the mounting groove 34 so that both the bracket 522 and the support plate 521 can slide and cooperate with the silo 3.

[0041] A support spring 524 is fixedly connected to the lower surface of the mounting block 523, and the lower end of the support spring 524 is fixed to the lower end groove wall of the mounting groove 34. The support spring 524 supports the mounting block 523, the bracket 522 and the support plate 521; when no fire bomb is placed on the support plate 521, the support plate 521 is located in the middle of the material tube 21; a horizontally arranged drive plate 525 is fixedly connected to the mounting block 523, and the drive plate 525 is located below the limit rod 51.

[0042] A hinged rod 526 is rotatably connected to the side wall of the silo 3 close to the material pipe 21, and the rotation axis of the hinged rod 526 is located in the middle of the hinged rod 526, and the hinged rod 526 is located between the driving plate 525 and the limiting rod 51; the hinged rod 526 is inclined, and the upper end of the hinged rod 526 is inclined in the direction away from the connecting pipe 31, and the lower end of the hinged rod 526 is hinged with a T-shaped connecting block 5261, and a connecting groove 5251 adapted to the connecting block 5261 is provided on the upper surface of the driving plate 525, and the length direction of the connecting groove 5251 is arranged along the length direction of the driving plate 525, and the connecting block 5261 is slidably inserted in the connecting groove 5251.

[0043] A connecting rod 527 is vertically fixedly connected to the side wall of the limiting rod 51 away from the silo 3. The connecting rod 527 is located at one end of the limiting rod 51 close to the hinged rod 526. The hinged rod 526 is provided with a connecting hole 5262 that passes through the hinged rod 526. The length direction of the connecting hole 5262 is set along the length direction of the hinged rod 526, and the hinged rod 526 is inserted into the connecting hole 5262.

[0044] When the fire bomb falls onto the support plate 521 through the connecting pipe 31, the fire bomb pushes the support plate 521, the bracket 522, the mounting block 523 and the driving plate 525 to move downward, and at the same time compresses the supporting spring 524. The driving plate 525 moves to drive the hinge rod 526 to rotate, and the lower end of the hinge rod 526 drives the connecting block 5261 to slide in the connecting groove 5251, and the upper end of the hinge rod 526 rotates toward the direction close to the connecting pipe 31. The hinge rod 526 cooperates with the connecting rod 527 through the connecting hole 5262 to push the limiting rod 51 to move, so that one end of the limiting rod 51 is inserted into the connecting pipe 31, and the limiting rod 51 prevents subsequent fire bombs from continuing to enter the connecting pipe 31, thereby reducing the accumulation of fire bombs in the connecting pipe 31; when the support plate 521 stops moving, the fire bomb on the support plate 521 contacts the adjacent fire bomb in the material tube 21, thereby limiting the fire bomb on the support plate 521.

[0045] As the launcher body 2 works, the launcher body 2 causes the fire bomb on the support plate 521 to move toward the launching end. When the fire bomb moves away from the support plate 521, the support spring 524 recovers its deformation and pushes the mounting block 523, the drive plate 525, the support rod 45 and the support plate 521 to move upward. At the same time, the drive plate 525 drives the hinge rod 526 to rotate, causing the upper end of the hinge rod 526 to rotate in the direction away from the connecting pipe 31. The hinge rod 526 cooperates with the connecting rod 527 and the connecting hole 5262 to pull the limit rod 51 to move outside the connecting pipe 31; when the support spring 524 returns to its initial state, the support plate 521, the drive plate 525, the hinge rod 526 and the limit rod 51 are all in the initial position. At this time, the limit rod 51 is outside the connecting pipe 31, and the fire bomb in the silo 3 can enter the connecting pipe 31.

[0046] The implementation principle of a fire bomb precision launching device in an embodiment of the present application is as follows: the operator opens the door and pulls the matching plate 46 downward so that the push plate 44 is located at the bottom of the silo 3, and the loading spring 47 is in a stretched state. At this time, the fire bomb is filled into the cavity, and then the door is closed and the matching plate 46 is released. The loading spring 47 restores its deformation and pulls the matching plate 46, the support rod 45 and the push plate 44 upward, so that the push plate 44 can continuously push the fire bomb upward to fill the position; in the process of fire extinguishing, when the fire bomb is separated from the support plate 521, the support spring 524 restores its deformation and pushes the support plate 521 and the drive plate 525 upward, and at the same time the hinged rod 526 rotates and pulls the limit rod 51 to move outside the connecting pipe 31.

[0047] The operator controls the hydraulic cylinder 43 to operate so that the push plate 44 pushes the fire bomb to move into the connecting pipe 31. After the fire bomb passes through the connecting pipe 31, it falls onto the support plate 521 and pushes the support plate 521 and the driving plate 525 to move downward. The driving plate 525 inserts the limit rod 51 into the connecting pipe 31 through the hinge rod 526; then the hydraulic cylinder 43 is controlled to operate so that the push plate 44 is reset. At this time, the push plate 44 pushes the remaining fire bomb to move upward; when the fire bomb is used up, the drone body 1 is controlled to return to the operation site, and then the fire bomb is replenished into the silo 3 again. The above operations are repeated until the fire is extinguished.

[0048] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
