Description

Technical Field

[0001] This application relates to the field of drone delivery technology, specifically a device for delivering fire extinguishing bombs. Background Technology

[0002] Currently, fire extinguishing bomb dispensers are widely used in fire fighting and emergency rescue. As an important fire extinguishing tool, the stability and flexibility of the dispenser directly affect the fire extinguishing effect and response speed. In existing technology, fire extinguishing bomb dispensers are usually installed on a bracket and fixed to the bracket by rigid connection methods such as bolts or screws.

[0003] However, using bolts or screws for fixing usually requires tools to tighten or loosen, which not only increases the complexity of operation, but also makes it inconvenient to adjust the position of the device when needed. Especially in emergency situations, operators may need to quickly adjust the position of the deployment device or replace the equipment. The traditional rigid connection method leads to time costs and waste of human resources.

[0004] Therefore, this application provides a fire extinguishing bomb dispensing device to solve the above problems. Utility Model Content

[0005] This application provides a fire extinguishing bomb dispensing device, which aims to solve the problem that fire extinguishing bomb dispensing devices mentioned in the background art are usually installed on brackets, and the traditional rigid connection method leads to the waste of operation time and human resources.

[0006] To achieve the above objectives, this application provides the following technical solution: a fire extinguishing bomb dispensing device, comprising a fixed frame mounted on a drone and a positioning frame mounted on the fixed frame, wherein a communication gimbal is fixedly mounted on the positioning frame, and a dispenser is provided at both ends of the fixed frame; The dispenser is equipped with a quick-release mechanism for quick assembly and disassembly with the fixing frame; The quick-release mechanism includes a receiving cavity opened in the dispenser and a fixed block fixedly installed at the center of the receiving cavity. Guide rails are installed on both sides of the fixed block, and one side of the guide rail is fixedly connected to the inner wall of the receiving cavity. Movable blocks are movably connected to both ends of the dispenser. A sub-plate for connecting with the guide rail is fixedly installed on the movable block. A locking block is fixedly installed at the lower end of the sub-plate. A number of sets of mounting holes for inserting the sub-plate are equidistantly provided on the fixing frame. A limiting block for locking and fixing the locking block is provided inside the mounting hole.

[0007] Preferably, guide blocks are fixedly installed on both sides of the sub-plate, and the guide blocks are slidably connected to the guide rail. This solves the problem that the movable block is prone to deviation when moving, which causes the sub-plate to fail to accurately match the mounting hole, and improves the accuracy and reliability of the quick-release mechanism connection.

[0008] Preferably, a telescopic rod is fixedly connected between the sub-plate and the fixed block. A spring is sleeved on the outside of the telescopic rod for connecting with the sub-plate. The end of the spring away from the sub-plate is fixedly connected to the fixed block. The elasticity of the spring is used to realize automatic locking and unlocking assistance between the dispenser and the fixed frame, solving the problems of laborious locking and unlocking and loose connection of traditional rigid connection.

[0009] Preferably, the bottom of the dispenser is provided with a moving groove for moving the sub-plate, and the moving groove is in communication with the accommodating cavity.

[0010] Preferably, the lower end of the engaging block has a rounded chamfer, and the upper end of the limiting block has a chamfer.

[0011] This dispensing device connects the dispensing device to the mounting holes of the fixed frame via a movable sub-plate on the dispenser. The locking block and the limiting block in the mounting hole work together to connect and lock the dispensing device to the fixed frame. When disassembly or adjustment is required, the locking can be released by reversing the operation. The quick-release mechanism replaces the traditional bolt or screw connection, solving the problem of inconvenient installation, adjustment and disassembly of the dispensing device, and providing basic support for the rapid deployment and maintenance of fire extinguishing bomb dispensing devices.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0015] This embodiment provides a fire extinguishing bomb dispensing device, such as... Figure 1-5 As shown, the delivery device includes a fixed frame 1 mounted on the drone and a positioning frame 3 set on the fixed frame 1. A communication gimbal 2 is fixedly mounted on the positioning frame 3, and a delivery device 4 is set at both ends of the fixed frame 1. The dispenser 4 is equipped with a quick-release mechanism 6 for quick assembly and disassembly with the mounting bracket 1; The quick-release mechanism 6 includes a receiving cavity opened by the dispenser 4 and a fixed block 61 fixedly installed at the center of the receiving cavity. Guide rails 64 are installed on both sides of the fixed block 61. One side of the guide rail 64 is fixedly connected to the inner wall of the receiving cavity. Movable blocks 62 are movably connected to both ends of the dispenser 4. A sub-plate 621 for connecting with the guide rail 64 is fixedly installed on the movable block 62. A locking block 63 is fixedly installed at the lower end of the sub-plate 621. Several sets of mounting holes 5 for inserting the sub-plate 621 are provided at equal intervals on the fixing frame 1. A limiting block 51 for locking and fixing the locking block 63 is provided inside the mounting hole 5.

[0016] Specifically, the fixed frame 1 serves as the mounting base for various components, the positioning frame 3 is used for positioning, the communication pan-tilt unit 2 enables communication, and the dispenser 4 performs the task of distributing fire extinguishing bombs. In the quick-release mechanism 6, within the cavity of the dispenser 4, the fixed block 61 and the guide rail 64 provide the mounting base for components such as the movable block 62. The movable block 62 is inserted into the mounting hole 5 of the fixed frame 1 through the sub-plate 621. The locking block 63 cooperates with the limiting block 51 in the mounting hole 5 to complete the connection and locking between the dispenser 4 and the fixed frame 1. When disassembly or position adjustment is required, the lock can be released by reversing the operation. The cavity of the dispenser 4 is 8cm long, 5cm wide, and 6cm high. The width of the movable block 62 is 2cm. The spacing between each set of mounting holes 5 is 10cm. The width of the mounting holes 5 is adapted to the movable block 62, and the position of the dispenser 4 can be adjusted as needed.

[0017] Guide blocks 622 are fixedly installed on both sides of the sub-plate 621, and the guide blocks 622 are slidably connected to the guide rail 64.

[0018] More specifically, the guide blocks 622 on both sides of the sub-plate 621 are embedded in the guide rail 64 and slide to provide guidance for the movement of the sub-plate 621, ensuring that the sub-plate 621 is accurately inserted into or pulled out of the mounting hole 5 in a straight line, and ensuring the precise connection and disassembly of the quick-release mechanism 6. The cooperation between the guide block 622 and the guide rail 64 ensures that the straightness error of the movement of the sub-plate 621 is ≤0.2mm. The guide block 622 is made of polytetrafluoroethylene.

[0019] A telescopic rod 67 is fixedly connected between the sub-plate 621 and the fixed block 61. A spring 66 for connecting with the sub-plate 621 is sleeved on the outside of the telescopic rod 67. The end of the spring 66 away from the sub-plate 621 is fixedly connected to the fixed block 61.

[0020] Furthermore, the telescopic rod 67 provides telescopic guidance for the movement of the sub-plate 621. The spring 66 is stretched and stores elastic potential energy when the sub-plate 621 moves away from the fixed block 61. When locking is required, the spring 66 releases elastic potential energy to pull the sub-plate 621 back to its original position, so that the locking block 63 is tightly locked with the limiting block 51. When disassembly is required, external force overcomes the elastic force of the spring 66 to move the sub-plate 621 and release the locking.

[0021] The bottom of the dispenser 4 is provided with a moving groove 65 for moving the sub-plate 621, and the moving groove 65 is connected to the accommodating cavity.

[0022] It should be noted that the movable groove 65 at the bottom of the dispenser 4 is connected to the accommodating cavity, providing a channel for the movement of the sub-plate 621, restricting the sub-plate 621 to move only along the direction of the movable groove 65, and ensuring that the insertion action of the sub-plate 621 and the mounting hole 5 is carried out on the predetermined trajectory.

[0023] The lower end of the locking block 63 is chamfered, and the upper end of the limiting block 51 is chamfered.

[0024] It is worth mentioning that the rounded chamfer at the lower end of the locking block 63 and the chamfer at the upper end of the limiting block 51, when the sub-plate 621 is inserted into the mounting hole 5, allow the locking block 63 to slide smoothly into the limiting block 51 to complete the locking, thus avoiding direct rigid collision between the two and causing jamming or damage.

[0025] In use, the fixed block 61 and guide rail 64 provide the mounting base for components such as the movable block 62. The movable block 62 is inserted into the mounting hole 5 of the fixed frame 1 through the sub-plate 621. The locking block 63 cooperates with the limiting block 51 in the mounting hole 5 to complete the connection and locking of the dispenser 4 and the fixed frame 1. During specific installation, the operator needs to hold the dispenser 4 and align it with the mounting hole 5 on the fixed frame 1. The sub-plate 621 on the movable block 62 of the dispenser 4 is inserted into the mounting hole 5. When the sub-plate 621 is inserted into the mounting hole 5, the locking block 63 can slide smoothly into the limiting block 51 to complete the locking through the guiding effect of the chamfer.

[0026] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
