A caterpillar-type fire monitor

Abstract

A tracked fire monitor includes a tracked remote-controlled vehicle. A fixed plate is connected to the body of the tracked remote-controlled vehicle, and a spray pipe is installed on the upper part of the fixed plate. A protective detachment mechanism is installed on the fixed plate. When a heavy object that affects the movement of the tracked remote-controlled vehicle falls, it will preferentially fall on the top plate, which may easily cause the aluminum limiting plate to break. If there is an unbroken aluminum limiting plate, personnel can control the positioning plate to retract into the fixed groove through the prefabricated detachment mechanism, thereby detaching the positioning plate from the aluminum limiting plate. At this time, the column of the protective frame touches the ground, and the protective frame can support the weight of the tracked remote-controlled vehicle and detach from the tracked remote-controlled vehicle. At this time, personnel can control the tracked remote-controlled vehicle to continue moving forward to extinguish the fire or to retreat backward, giving the tracked remote-controlled vehicle another chance to escape.

Description

Technical Field

[0001] This invention relates to a fire monitor, and more specifically, a tracked fire monitor. Background Technology

[0002] Existing tracked fire monitors are generally used to replace personnel in entering more dangerous areas to fight fires. When operating in fire scenes in more dangerous areas, tracked fire monitors are inevitably crushed by falling furniture, wood, and building structural components, causing them to become trapped. Summary of the Invention

[0003] The purpose of this invention is to provide a tracked fire monitor that combines a protective detachment mechanism, a protective frame, and a prefabricated detachment mechanism. When falling furniture, wood, or building structural components press on the device, they will preferentially contact the protective frame. Lighter objects that do not affect the movement of the tracked remote-controlled vehicle will be directly blocked by the top plate, allowing the tracked remote-controlled vehicle to continue moving. When heavier objects that affect the movement of the tracked remote-controlled vehicle fall, they will also preferentially land on the top plate, which may cause the aluminum limiting plate to break. If there is an unbroken aluminum limiting plate, personnel can use the prefabricated detachment mechanism to control the positioning plate to retract into the fixed groove, thereby detaching the positioning plate from the aluminum limiting plate. At this time, the column of the protective frame touches the ground, and the protective frame can support the weight of the tracked remote-controlled vehicle and detach from it. At this time, personnel can control the tracked remote-controlled vehicle to continue moving forward to extinguish the fire or to retreat backward, giving the tracked remote-controlled vehicle another chance to escape.

[0004] To achieve the above objectives, the present invention employs the following technical solution:

[0005] A tracked fire monitor includes a tracked remote-controlled vehicle. A fixed plate is connected to the body of the tracked remote-controlled vehicle. A spray pipe is installed on the upper part of the fixed plate. A protective release mechanism is installed on the fixed plate. The protective release mechanism includes a protective frame and a prefabricated release mechanism. The protective frame includes a top plate, which is a square plate structure. Two sets of supports are installed at the bottom of the top plate. Each set of supports includes two columns. A column is connected to each of the four corners of the top plate. The prefabricated release mechanism includes a pusher. A fixing groove is opened in the middle of the fixed plate. The fixing groove is a through groove. A positioning plate is inserted into the openings at both ends of the fixing groove. The pusher can control the positioning plate to slide inside the fixing groove. An aluminum limiting plate is connected to one side of the column. The bottom of the aluminum limiting plate can cooperate with the positioning plate.

[0006] To further achieve the objectives of this invention, the following technical solution can also be adopted: the pusher includes a third stepper motor, the fixed end of the third stepper motor is connected to the inner wall of the fixed groove, the output shaft of the third stepper motor is connected to a gear, one side of each of the two positioning plates is connected to a first rack and a second rack respectively, the first rack and the second rack respectively mesh with the two sides of the gear, one side of each positioning plate is connected to a U-shaped plate, the U-shaped plate and the second rack can cooperate to clamp the gear and the first rack, the first rack can be inserted into the inner side of the U-shaped plate, and the first rack can slide along the inner side of the U-shaped plate.

[0007] An adjustment mechanism is installed on the upper part of the fixed plate. The adjustment mechanism includes a second stepper motor. The fixed end of the second stepper motor is connected to the fixed plate. The output shaft of the second stepper motor is connected to a rotating rod. One end of the rotating rod is connected to a first stepper motor. The housing of the first stepper motor is fitted with the rotating rod. The output shaft of the first stepper motor is connected to a spray pipe. One end of the spray pipe is connected to a fire hose connector.

[0008] A fracture groove is formed on the upper part of the aluminum limiting plate.

[0009] The tracked remote-controlled vehicle has protruding ribs connected to its tracks.

[0010] The advantages of this invention are as follows: By combining a protective detachment mechanism, a protective frame, and a prefabricated detachment mechanism, when falling furniture, wood, and building structural components press on this device, they will preferentially contact the protective frame. Lighter objects that do not affect the movement of the tracked remote-controlled vehicle will be directly blocked by the top plate, allowing the tracked remote-controlled vehicle to continue moving. When heavier objects that affect the movement of the tracked remote-controlled vehicle fall, they will also preferentially land on the top plate, which may easily cause the aluminum limiting plate to break. If there is an unbroken aluminum limiting plate, personnel can use the prefabricated detachment mechanism to control the positioning plate to retract into the fixed groove, thereby detaching the positioning plate from the aluminum limiting plate. At this time, the upright of the protective frame touches the ground, and the protective frame can bear the weight of the tracked remote-controlled vehicle and detach from it. At this time, personnel can control the tracked remote-controlled vehicle to continue moving forward to extinguish the fire or to retreat backward, giving the tracked remote-controlled vehicle another chance to escape.

[0017] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. Example 1

[0018] A tracked fire monitor, such as Figures 1-5 As shown, the system includes a tracked remote-controlled vehicle 8. A fixed plate 7 is connected to the body of the tracked remote-controlled vehicle 8. A spray pipe 3 is installed on the upper part of the fixed plate 7. A protective detachment mechanism is installed on the fixed plate 7. The protective detachment mechanism includes a protective frame and a pre-determination detachment mechanism. The protective frame includes a top plate 1, which is a square plate structure. Two sets of supports are installed at the bottom of the top plate 1. Each set of supports includes two columns 2. A column 2 is connected to each of the four corners of the top plate 1. The pre-determination detachment mechanism includes a pusher. A fixing groove 10 is opened in the middle of the fixed plate 7. The fixing groove 10 is a through groove. A positioning plate 11 is inserted into the openings at both ends of the fixing groove 10. The pusher can control the positioning plate 11 to slide inside the fixing groove 10. An aluminum limiting plate 12 is connected to one side of the column 2. The bottom of the aluminum limiting plate 12 can cooperate with the positioning plate 11.

[0019] This invention combines a protective detachment mechanism, a protective frame, and a prefabricated detachment mechanism. When falling furniture, wood, or building structural components press on this device, they will preferentially contact the protective frame. Lighter objects that do not affect the movement of the tracked remote control vehicle 8 will be directly blocked by the top plate 1, allowing the tracked remote control vehicle 8 to continue moving. When heavier objects that affect the movement of the tracked remote control vehicle 8 fall, they will also preferentially land on the top plate 1, which may cause the aluminum limiting plate 12 to break. If there is an unbroken aluminum limiting plate 12, personnel can use the prefabricated detachment mechanism to control the positioning plate 11 to retract into the fixing groove 10, thereby detaching the positioning plate 11 from the aluminum limiting plate 12. At this time, the column 2 of the protective frame touches the ground, and the protective frame can support the tracked remote control vehicle 8 and detach from it. At this time, personnel can control the tracked remote control vehicle 8 to continue moving forward to extinguish the fire or to retreat backward, giving the tracked remote control vehicle 8 another chance to escape.

[0020] Specific material selection and feasibility analysis: The samples we actually made were based on the drawings in the instruction manual. The proportions and fit methods of each component in the drawings were implemented. The connections were common methods such as strong adhesive connection, welding, riveting, flange connection, and one-piece molding connection. In actual production, the corresponding connection method, thickness and strength of the connection point can be selected according to the actual connection strength requirements without creative design. Example 2

[0021] A tracked fire monitor, such as Figures 1-5 As shown, the system includes a tracked remote-controlled vehicle 8. A fixed plate 7 is connected to the body of the tracked remote-controlled vehicle 8. A spray pipe 3 is installed on the upper part of the fixed plate 7. A protective detachment mechanism is installed on the fixed plate 7. The protective detachment mechanism includes a protective frame and a pre-determination detachment mechanism. The protective frame includes a top plate 1, which is a square plate structure. Two sets of supports are installed at the bottom of the top plate 1. Each set of supports includes two columns 2. A column 2 is connected to each of the four corners of the top plate 1. The pre-determination detachment mechanism includes a pusher. A fixing groove 10 is opened in the middle of the fixed plate 7. The fixing groove 10 is a through groove. A positioning plate 11 is inserted into the openings at both ends of the fixing groove 10. The pusher can control the positioning plate 11 to slide inside the fixing groove 10. An aluminum limiting plate 12 is connected to one side of the column 2. The bottom of the aluminum limiting plate 12 can cooperate with the positioning plate 11. The pusher includes a third stepper motor 14, the fixed end of which is connected to the inner wall of the fixed groove 10. The output shaft of the third stepper motor 14 is connected to a gear 15. One side of each of the two positioning plates 11 is connected to a first rack 13 and a second rack 16, which mesh with the two sides of the gear 15. One side of each positioning plate 11 is connected to a U-shaped plate 17, which can cooperate with the second rack 16 to clamp the gear 15 and the first rack 13. The first rack 13 can be inserted into the inner side of the U-shaped plate 17 and can slide along the inner side of the U-shaped plate 17.

[0022] The pusher of the present invention can rotate the gear 15 by the third stepper motor 14 when it is necessary to detach the protective frame from the tracked remote control vehicle 8. This rotation will simultaneously drive the second rack 16 and the first rack 13 to slide, thereby simultaneously driving the two positioning plates 11 to be retracted into the fixed groove 10. This will cause the positioning plates 11 to detach from the aluminum limiting plate 12, thus removing the connection between the protective frame and the tracked remote control vehicle 8 and facilitating the separation of the protective frame from the tracked remote control vehicle 8.
