Description

Technical Field

[0001] The utility model relates to the technical field of outdoor fire fighting, in particular to a flame retardant spraying device for forest and grassland fire prevention. Background Art

[0002] Flame retardant for forest and grassland fire prevention is a chemical substance used to prevent and control forest and grassland fires. Its main function is to reduce the flammability of flammable materials and stop the spread of fire. Flame retardant is usually sprayed on vegetation or the ground to form a protective barrier to reduce the risk of fire or slow down the fire.

[0003] The common flame retardant spraying device for forest and grassland fire prevention is unable to adjust its position to move back and forth and spray repeatedly as needed due to the limitation of the fixed mechanism. This results in uneven spraying effect when covering large areas or key areas, and some areas may not be fully protected. In addition, when the driving speed is slightly faster, the spraying device lacking a wind shield mechanism is easily affected by wind, resulting in unstable spraying direction and range, and the flame retardant may not be evenly distributed in the target area.

[0004] Therefore, due to the limitations of the fixing mechanism, the above-mentioned flame retardant spraying device for forest and grassland fire prevention cannot adjust its position as needed to move back and forth and spray repeatedly. This results in uneven spraying effect when covering large areas or key areas, and some areas may not be fully protected. In addition, when the driving speed is slightly faster, the spraying device lacking a wind shielding mechanism is easily affected by wind, resulting in unstable spraying direction and range, and the flame retardant may not be evenly distributed in the target area. This problem urgently needs to be solved to improve the use scenarios of the flame retardant spraying device for forest and grassland fire prevention. Utility Model Content

[0005] In order to overcome the common flame retardant spraying device for forest and grassland fire prevention, due to the limitations of the fixed mechanism, the spraying device cannot adjust its position as needed to move back and forth and spray repeatedly. This results in uneven spraying effects when covering large areas or key areas, and some areas may not be fully protected. In addition, when the driving speed is slightly faster, the spraying device lacks a wind shield mechanism and is easily affected by wind, resulting in unstable spraying direction and range, and the flame retardant may not be evenly distributed in the target area.

[0006] The technical solution of the utility model is: a flame retardant spraying device for forest and grassland fire prevention, comprising a base, mounting mechanisms are arranged on the front and rear sides of the base, a moving mechanism is arranged on the upper end of the base, the moving mechanism comprises a support column, a limit rod, a sliding block, a sprayer, an adapter groove, a motor, a gear, a rack, a slide groove, and a slider; the left and right sides of the upper end of the base are connected with support columns at equal intervals, two limit rods are connected between the two support columns, the outer ends of the two limit rods are slidably connected with the sliding blocks, the outer side of the sliding block is connected with the sprayer, the upper end of the base is provided with an adapter groove, the inside of the adapter groove is connected with the motor, the front end of the sliding block is provided with a windproof mechanism, and the front end of the sliding block is provided with an auxiliary mechanism.

[0007] Preferably, by setting up a moving mechanism, the sprayer can be made to move back and forth, thereby quickly and repeatedly spraying the target area, improving the spraying efficiency, and in combination with a windproof mechanism, the wind pressure generated when the vehicle speed is slightly faster can be reduced, thereby ensuring the spraying quality, so as to solve the problem that the existing flame retardant spraying device cannot move back and forth and spray repeatedly due to the limitation of the fixed mechanism, resulting in uneven spraying effect over a large area or in key areas, and some areas cannot be fully protected. In addition, the lack of a windproof mechanism makes the device affected by wind when the vehicle speed is slightly faster, resulting in unstable spraying direction and range, and uneven distribution of flame retardant.

[0008] Preferably, the output end of the motor is connected to a gear, which is rotatably connected to the adapter groove, and the lower end of the sliding block is connected to a rack, which is meshingly connected to the gear. When the motor is started, the motor drives the gear to rotate on the adapter groove, thereby driving the rack to mesh, and the rack drives the sliding block to slide on the limit rod, thereby driving the sprayer to move back and forth, thereby achieving repeated spraying of the target area and improving work efficiency.

[0009] Preferably, a sliding groove is provided on the front side of the upper end of the base, and a sliding block is connected to the front side of the lower end of the sliding block. The sliding block is slidably connected to the sliding groove, and the sliding of the sliding block drives the sliding of the sliding groove. The sliding block can provide support force on the front side of the sliding block to reduce the pressure of the limiting rod.

[0011] Preferably, two limit plates are provided and two wind shields are provided, and the wind shields are movably connected to the limit plates. When the vehicle speed is too fast, the wind pressure will push the wind shields to slide on the sliding grooves, so that the wind shields are close to the nozzle of the sprayer to ensure the water pressure when the sprayer sprays, and the wind shield on the other side slides on the sliding groove to provide an offset distance for the flame retardant spraying to prevent blocking the normal spraying of the flame retardant.

[0012] Preferably, the mounting mechanism includes a mounting plate and mounting screws; mounting plates are connected to the left and right sides of the front and rear ends of the base at equal intervals, and four mounting plates are provided. The upper ends of the four mounting plates are all threaded with mounting screws, and the mounting plates are installed on the working vehicle through the mounting screws, thereby facilitating the installation of the device.

[0013] Preferably, the auxiliary mechanism includes a drawer and a workbench; the front end of the sliding block is slidably connected to the drawer, and the upper side of the sliding block is provided with a workbench. The drawer can store multiple flame retardants or flame retardant raw materials, and the workbench is convenient for staff to operate, such as opening the flame retardant or mixing the flame retardant raw materials.

When the vehicle speed is too fast, the wind pressure will push the windshield to slide on the sliding groove, so that the windshield is close to the nozzle of the sprayer to ensure the water pressure when the sprayer sprays, and the windshield on the other side slides on the sliding groove to provide an offset distance for the flame retardant spraying, thereby preventing the normal spraying of the flame retardant from being blocked, ensuring the quality of the spraying, and improving practicality.
