Description

Technical Field

[0001] The utility model relates to the technical field of land fire-fighting vehicles, in particular to a fire-fighting sand-throwing robot and a sand-throwing machine. Background Art

[0002] For oil fires and water-sensitive hazardous chemical fires in waterless desert areas, sand-throwing fire-fighting methods are generally used for rescue. In order to improve the efficiency and safety of firefighting of oil fires and water-sensitive hazardous chemical fires in waterless desert areas, sand-throwing fire-fighting vehicles generally have a spreading system inside to blow out the sand in the vehicle for fire extinguishing.

[0003] For example, a Chinese utility model patent with authorization announcement number CN210433876U discloses an independently powered sand-throwing fire-extinguishing device and a sand-throwing fire-extinguishing vehicle, including a sand box assembly and a scattering system; the sand box assembly includes a cargo box for storing sand, a feeding bottom plate arranged at the bottom of the cargo box for conveying sand to a feeding auger, and a feeding auger for slinging the sand into the scattering system; the scattering system includes a rotatable scattering impeller for scattering sand outward. There is also a Chinese utility model patent with authorization announcement number CN216653203U that discloses a fire-fighting sand injection device, including a vehicle body, on which are provided a sand storage box, a sand suction box, a support rod, a first motor, an air compressor and a control device, the bottom of the sand storage box is connected to the top of the sand suction box, and ventilation pipes and sand suction hoses are respectively connected on both sides of the sand suction box, the support rod is rotatably connected to the vehicle body, and the lower part, middle part and top part of the support rod are respectively provided with passive bevel gears, electric telescopic rods and spray barrels, the spray barrels are hinged to the support rod, and an air amplifier is provided at the end of the spray barrel, the air amplifier is connected to the sand suction hose, and the two ends of the electric telescopic rod are respectively hinged to the support rod and the spray barrel, an active bevel gear meshing with the passive bevel gear is provided on the output shaft of the first motor, and the air compressor is connected to the air amplifier through an intake hose.

[0004] However, the fire extinguishing devices of the above patents are all moved to the vicinity of the area where fire needs to be extinguished through a vehicle body carrying sand and then sprayed sand on the area where fire needs to be extinguished through a sandblasting device. Since the vehicle body carries a large amount of sand and the vehicle body is heavy, it can only be moved on a relatively flat paved road. When the area where fire needs to be extinguished is on a Gobi desert, sandy land or other ground, the vehicle body is often too heavy to get close, and the sandblasting distance of the sandblasting device is also very limited, which leads to greater restrictions on its use. Utility Model Content

[0005] The utility model aims to provide a fire-fighting sand-throwing robot, which is used to solve the problem that when the existing fire-fighting device is in the Gobi desert, sandy ground or other areas where fire needs to be extinguished, the vehicle body is often too heavy to approach, and the sand-blasting distance of the sand-blasting device is also very limited, which leads to greater restrictions on use.

[0006] The utility model adopts the following technical scheme: a fire-fighting sand-throwing robot, comprising a mobile trolley, on which a sand-throwing device is arranged, the sand-throwing device comprises a sand inlet and a sand-blasting port, the sand inlet is used to be connected with a sand conveying pipeline, the mobile trolley is also provided with a driving mechanism, the sand-throwing device is connected with the driving mechanism to throw sand out through the sand-blasting port to realize fire extinguishing.

[0010] Furthermore, the mobile vehicle also includes a protective cover, the mobile chassis is located below the protective cover, and the driving mechanism and the sand throwing device are located inside the protective cover.

[0011] The fire-fighting sand-throwing robot of the utility model is a pioneering invention. The beneficial effects of the fire-fighting sand-throwing robot of the utility model are as follows: since the mobile trolley is provided with a sand inlet connected to the sand conveying pipeline, the sand is then thrown to the fire scene through the sand blasting port through the driving mechanism; since the fire-fighting sand-throwing robot does not need to be loaded with sand but is connected to the sand conveying pipeline, the overall structure is relatively small and convenient for walking on the Gobi desert, sandy land and other grounds; the sand conveying pipeline can be set to different lengths as needed; therefore, the fire-fighting sand-throwing robot can also walk to a longer distance and then perform sand-raising operations; the sand blasting distance can be controlled as needed, thereby realizing long-distance firefighting and having a wider scope of application.

[0012] The utility model aims to provide a sand throwing machine, which is used to solve the problem that the existing fire extinguishing device cannot realize long-distance spraying work and can only be moved in a relatively flat place, thus being greatly limited.

[0015] Furthermore, the mobile chassis of the mobile vehicle is a crawler chassis.

[0016] Furthermore, the driving mechanism is also connected to the mobile chassis.

[0017] Furthermore, the mobile vehicle also includes a protective cover, the mobile chassis is located below the protective cover, and the driving mechanism and the sand throwing device are located inside the protective cover.

[0018] The sand throwing machine of the utility model improves the existing sand throwing machine. The beneficial effect of the sand throwing machine of the utility model is that the sand loading vehicle is connected with the fire-fighting sand throwing robot through the sand conveying pipeline, so that the sand loading vehicle can be parked on a flat paved road surface. Since the mobile vehicle is provided with a sand inlet connected with the sand conveying pipeline, the sand is then thrown to the fire scene through the sand spraying port through the driving mechanism. Since the fire-fighting sand throwing robot does not need to be loaded with sand but is connected with the sand conveying pipeline, the overall structure is relatively small and convenient for walking on the Gobi desert, sandy land and other grounds. The sand conveying pipeline can be set to different lengths as needed. Therefore, the fire-fighting sand throwing robot can also walk to a longer distance and then perform sand raising operations. The sand spraying distance can be controlled as needed, thereby realizing long-distance firefighting and having a wider range of applications. BRIEF DESCRIPTION OF THE DRAWINGS

[0022] The features and performance of the present invention are further described in detail below in conjunction with the embodiments.

[0023] First, the technical solution of the utility model is generally described as follows:

[0024] The utility model is based on the existing method of using sand-throwing extinguishing vehicles to extinguish fires in waterless desert areas. The sand-throwing extinguishing vehicle moves to the vicinity of an area where fire needs to be extinguished through a vehicle body with sand, and then sprays sand to the area where fire needs to be extinguished through a sand-blasting device. Since the vehicle body carries a large amount of sand and soil, the vehicle body is heavy and can only be moved on a relatively flat paved road. When the area where fire needs to be extinguished is on a Gobi desert, sandy land or other ground, the vehicle body is often unable to approach due to its heavy weight, and the sand-blasting distance of the sand-blasting device is also very limited, which results in greater restrictions on use.

[0025] Based on the above problems, the utility model designs a sand throwing machine to realize long-distance fire extinguishing, and conceives how to extinguish fires more conveniently and safely in areas with uneven roads, so as to realize long-distance firefighting operations. The following technical solutions are specifically adopted: the sand throwing machine of the utility model comprises a sand loading vehicle, and the sand storage box of the sand loading vehicle is connected to a fire-fighting sand throwing robot through a sand conveying pipeline, so that the sand loading vehicle can stop on a flat paved road surface, and the fire-fighting sand throwing robot can be operated to realize sand throwing and fire extinguishing. Specifically, the fire-fighting sand throwing robot comprises a mobile trolley, and a sand throwing device is provided on the mobile trolley. The device includes a sand inlet and a sand blasting port. The sand inlet is used to connect with a sand conveying pipeline. The mobile trolley is also provided with a driving mechanism. The sand throwing device is connected with the driving mechanism to blow sand out through the sand blasting port to achieve fire extinguishing. Since the fire-fighting sand-throwing robot does not need to be loaded with sand, but is connected with the sand conveying pipeline, the overall structure is relatively small, which is convenient for walking on the Gobi Desert, sandy land and other grounds. The sand conveying pipeline can be set to different lengths as needed. Therefore, the fire-fighting sand-throwing robot can also walk to a longer distance before performing sand-blowing operations. The sand-blasting distance can be controlled as needed, thus realizing long-distance firefighting and having a wider range of applications.

[0026] The specific embodiment of the sand throwing machine of the utility model:

[0027] The structural schematic diagram of the sand throwing machine of the utility model is as follows Figure 1 As shown, a sand throwing machine includes a sand loading vehicle 1, on which a fire extinguishing agent storage tank 2 is arranged, and the fire extinguishing agent storage tank 2 is used to hold sand and soil. The sand loading vehicle 1 is connected to a fire extinguishing sand throwing robot 6 through a sand conveying pipeline 5. Specifically, the sand conveying pipeline 5 is connected to the fire extinguishing agent storage tank 2. The structural schematic diagram of the fire extinguishing sand throwing robot 6 is shown in FIG. Figure 2 As shown, the fire-fighting sand-throwing robot 6 includes a mobile trolley, on which a sand-throwing device is provided. The sand-throwing device includes a sand inlet and a sand-blasting port. The sand inlet is used to be connected to the sand transport pipeline 5. The mobile trolley is also provided with a driving mechanism. The sand-throwing device is connected to the driving mechanism to throw sand out through the sand-blasting port to achieve fire extinguishing.

[0028] The mobile cart can be moved by an operator, but it is dangerous for people to be close to a fire source. Therefore, in order to keep the operator away from the dangerous scene, in this embodiment, preferably, the mobile cart is an unmanned cart, and the mobile cart is equipped with a wireless remote control. In this way, the remote control is flexible, easy to operate, and safe to operate, which effectively protects the safety of the operator, saves personnel costs, and improves the efficiency of fighting special fires.

[0029] In order to make the fire-fighting sand-throwing robot 6 more stable and reliable during movement, and convenient for walking on uneven ground such as sand and Gobi Desert, preferably, the mobile chassis of the mobile vehicle is a crawler chassis 7, which is more stable during walking, has a large contact area with the ground, and can ensure more reliability regardless of the road conditions. Of course, in other embodiments, the mobile chassis can also be a common wheeled chassis.

[0030] In order to reduce the size of the sand loading vehicle 1 or facilitate local material collection, preferably, the sand loading vehicle 1 is also provided with a sand suction device 3, and the sand suction device 3 is connected to a sand suction pipe 4, so that the sand loading vehicle 1 can collect materials locally where there is sand and soil, which is convenient to use, and the size and weight of the whole vehicle can be smaller, which is convenient to use and saves costs.

[0031] In this embodiment, the driving mechanism includes a diesel engine 13 for providing power, the diesel engine 13 is connected to a hydraulic motor 12 and a transmission 10, and the transmission 10 is connected to a sand throwing impeller 9. The sand throwing amount varies according to the speed of the sand throwing impeller 9, which can reach 25-50m³ / h, and the sand throwing distance is between 23-30 meters. The diesel engine 13 is also connected to the mobile chassis in a transmission manner, and power is provided to the mobile chassis, so that the sand throwing operation and the moving operation are through the same driving mechanism, making the overall structure more compact and cost-saving.

[0032] In order to protect the equipment inside the mobile cart and increase the service life of the mobile cart, preferably, the mobile cart also includes a protective cover, the mobile chassis is located under the protective cover, and the driving mechanism and the sand throwing device are located inside the protective cover, so that the driving mechanism will not be damaged by sand during long-term operation, thereby improving the protection effect of the mobile cart.

[0033] The mobile trolley is also provided with a sand conveying pipe 8 and a sand throwing pipe 11. The sand conveying pipe 8 is located at the bottom position of the protective cover of the fire-fighting sand throwing robot 6 and extends out of the protective cover. The sand conveying pipe 8 is used to communicate with the sand conveying pipeline 5 of the sand loading vehicle 1. One end of the sand conveying pipe 8 located outside the protective cover constitutes a sand inlet. The sand throwing pipe 11 includes a lower vertical section and an upper inclined section. The upper inclined section is set at an angle of 45 degrees, and the end opening of the inclined section constitutes a sand blasting port. The sand throwing impeller 9 is located between the sand conveying pipe 8 and the sand throwing pipe 11. In this way, when the sand throwing impeller 9 rotates at high speed, the sand can have a better parabola, and sand throwing over a larger distance can be achieved, so that the sand conveyed by the sand conveying pipe 8 can be thrown out through the sand throwing pipe 11 to achieve fire extinguishing.

[0034] Through the above description of the specific embodiments of the sand throwing machine of the utility model, it can be seen that the sand loading vehicle of the sand throwing machine of the utility model is connected with the fire-fighting sand throwing robot through the sand conveying pipeline, so that the sand loading vehicle can be parked on a flat paved road surface. Since the mobile vehicle is provided with a sand inlet connected with the sand conveying pipeline, the sand is then thrown to the fire scene through the sand blasting port through the driving mechanism. Since the fire-fighting sand throwing robot does not need to be loaded with sand but is connected with the sand conveying pipeline, the overall structure is relatively small and convenient for walking on the Gobi Desert, sandy land and other grounds. The sand conveying pipeline can be set to different lengths as needed. Therefore, the fire-fighting sand throwing robot can also walk to a longer distance and then perform sand raising operations. The sand blasting distance can be controlled as needed, thus realizing long-distance firefighting and having a wider range of applications.

[0035] The embodiment of the fire-fighting sand-throwing robot of the present invention is the same as the embodiment of the fire-fighting sand-throwing robot in the above-mentioned sand-throwing machine, and therefore will not be described again.
