Description

Technical Field

[0001] The invention belongs to the technical field of emergency vehicles for digging forest fire prevention ditches, and in particular relates to an emergency vehicle for digging forest fire prevention ditches. Background Art

[0002] Because forest fires burn very quickly, if people do not put out the fire in time, the fire will quickly spread to other large areas. Therefore, it is necessary to quickly dig a fire-prevention ditch to prevent the spread of forest fires.

[0003] For example, a Chinese patent with publication number CN112933463B discloses a forest fire prevention ditch digging emergency vehicle, including a vehicle body, a push-out cavity is opened in the vehicle body, the lower side of the push-out cavity is connected to a digging cavity with an opening downward, a digging plate is fixedly provided on one side wall of the digging cavity, the lower end of the digging plate extends to the lower side of the vehicle body, and a digging shovel is fixedly provided on the upper and lower sides of an end surface of the digging plate facing the other side wall of the digging cavity, a cam cavity is connected to a side wall of the push-out cavity away from the opening, a reciprocating push plate mechanism is provided in the cam cavity, a soil breaking mechanism is provided on the lower side of the vehicle body and on the side of the digging cavity opposite to the digging plate, and the soil breaking mechanism can separate the soil. The forest fire prevention ditch digging emergency vehicle can first crush the soil during digging, and moisten the soil by spraying water, which is beneficial to the digging of the soil, further improving the efficiency of digging, and increasing the fire extinguishing effect.

[0004] The above patent has the following problems:

[0005] This patent has some disadvantages when in use, such as: when the above device is in use, the fire truck needs to move forward to push the device forward. If the fire truck encounters an unavoidable emergency and cannot reach the designated location in time, the above device cannot be used; at the same time, the soil is excavated and crushed by the soil-breaking shaft and the spiral blade, and the excavation process is too slow to quickly form an effective fire prevention ditch. Even if water is sprayed on the soil, it will evaporate quickly under the baking of the fire, and the fire prevention effect is also poor. In view of this, we propose an excavation emergency vehicle for forest fire prevention ditches. Summary of the invention

[0060] Embodiment 1:

[0061] See also Figure 1-10 As shown in the figure, this embodiment provides an emergency excavation vehicle for forest fire prevention trenches, including:

[0062] A vehicle body 1, in which a movable groove 11 is provided, in which a limit plate 1 21, a limit plate 22, a rotating column 23 and a digging block 24 are provided in sequence from front to back, a plurality of plows 1 211 and a plurality of plows 221 are provided at the bottom of the limit plate 1 21 and the limit plate 22, respectively, a plurality of crushing knives 231 are provided on the rotating column 23, and soil driving blocks 241 are provided on both sides of the digging block 24;

[0063] Two rotating shafts 4, the two rotating shafts 4 are symmetrically mounted in the vehicle body 1, and both ends of the two rotating shafts 4 are coaxially connected with rollers 41;

[0064] A power assembly, which is located in the vehicle body 1 and is used to drive the rotating column 23 and one of the rotating shafts 4 to rotate;

[0065] A lifting assembly is located in the vehicle body 1 and is used to drive the limit plate 1 21, the limit plate 22, the rotating column 23 and the digging block 24 to move up and down;

[0066] A storage box 5, which is fixedly mounted on the top of the vehicle body 1, and has a storage cavity 1 51 and a storage cavity 2 52;

[0067] Two discharge pipes 7, which are symmetrically fixedly installed on the rear side of the storage box 5 and are both connected to the second storage chamber 52;

[0068] A water distribution pipe 61, which is fixedly installed in the vehicle body 1, and a plurality of spray pipes 62 are provided on both sides of the water distribution pipe 61 and located in the vehicle body 1, and a tail end of the water distribution pipe 61 is located between the two discharge pipes 7 and fixedly installed with a faucet 63;

[0069] The infusion assembly is located at the top of the storage box 5 and is used to transport the storage chamber 1 51 to the water distribution pipe 61.

[0070] Among them, through the storage chamber 1 51 and the storage chamber 2 52, the personnel can put appropriate amounts of water and dry ice in the storage chamber 1 51 and the storage chamber 2 52 respectively. Then, the personnel start the power component and the lifting component, and the lifting component drives the limit plate 1 21, the limit plate 22, and the plurality of crushing knives 231 and the digging block 24 on the rotating column 23 to move downward in the movable groove 11 and penetrate into the ground. At the same time, the power component drives the rotating column 23 and one of the rotating shafts 4 to rotate, and one of the rotating shafts 4 drives the corresponding two rollers 41 to roll on the ground, and the other rotating shaft 4 drives the corresponding two rollers 41 to roll on the ground, so that the vehicle body 1 can move forward, and the forward movement of the vehicle body 1 can drive the limit plate 1 21, the limit plate 22, The rotating column 23 and the soil-digging block 24 move forward together. At the same time, the limiting plate 1 21 and the limiting plate 22 respectively drive the plurality of plows 1 211 and the plurality of plows 221 to turn over the ground. Subsequently, the rotating rotating column 23 drives the plurality of crushing knives 231 to rotate and cut and crush the turned over soil. At this time, the excavated fire ditch has been formed, and the soil-digging block 24 also enters the fire ditch, and the two soil-driving blocks 241 are attached to the ground. The forward soil-digging block 24 squeezes the crushed soil and moves upward in the fire ditch until it is located at the top of the fire ditch and enters the two soil-driving blocks 241. Under the driving action of the soil-driving blocks 241, the soil can be dispersed to a farther position to avoid affecting the rolling of the roller 41 on the ground. Now there is no crushed soil in the fire ditch.

[0071] While the plurality of plows 1 211 and the plurality of plows 221 are turning the soil on the ground, the infusion assembly is also started, and the infusion assembly sucks out the water in the storage chamber 1 51 and transports it to the water distribution pipe 61. Under the action of water pressure, the water in the water distribution pipe 61 is sprayed out as atomized liquid through the plurality of spray pipes 62 and falls on the turned soil and broken soil, so that the soil is wetted, and the wetted soil is ensured to be dispersed on both sides of the fireproof ditch by the two soil-displacing blocks 241 to form the first layer of fireproof barrier;

[0072] Afterwards, the personnel can open the faucet 63 so that the water in the water distribution pipe 61 falls into the fireproof ditch through the faucet 63, and the dry ice in the storage chamber 2 52 is also discharged into the fireproof ditch through the two discharge pipes 7, so that the dry ice reacts with water to generate carbon dioxide gas. Dry ice, that is, solid carbon dioxide, is easy to sublimate at room temperature, and its sublimation process is an endothermic process. When dry ice is placed in water, it will quickly sublime into carbon dioxide gas. During this process, the carbon dioxide gas forms bubbles in the water and rises, which appears as the phenomenon of "boiling" of water. In fact, this is the small water droplets formed by the liquefaction of water vapor in the surrounding air due to the absorption of heat by the sublimation of dry ice, rather than real boiling of water. Therefore, the direct product of the reaction of dry ice and water is carbon dioxide gas, and carbon dioxide gas is denser than air. Therefore, a large amount of carbon dioxide gas will still be concentrated in the fireproof ditch, thereby forming a second layer of fireproof barrier;

[0073] Through the above operations, when the overall device is in operation, it does not need the assistance of fire trucks to move forward, and can dig a fire ditch in time. At the same time, with the cooperation of several plows 211, several plows 221, rotating columns 23, crushing knives 231, digging blocks 24 and driving blocks 241, an effective fire ditch that can be used can be quickly dug on the ground, and appropriate amounts of water and dry ice are respectively put into storage chamber 1 51 and storage chamber 2 52, so that the water in the water distribution pipe 61 falls into the fire ditch through the faucet 63, and the dry ice in the storage chamber 2 52 is also discharged into the fire ditch through two discharge pipes 7, so that the dry ice reacts with water to generate carbon dioxide gas, which can further improve the fire prevention effect of the fire ditch.

[0074] It is worth noting that the plurality of plows 1 211 and the plurality of plows 221 are all inclined structures, and the downward inclination angle of the plurality of plows 1 211 and the plurality of plows 221 is 2-5°.

[0107] Among them, ensure the structural stability of the water distribution pipe 61 and the plurality of spray pipes 62; ensure the safety of the tail end of the spray pipe 62. When the dry ice in the discharge pipe 7 needs to be removed, the baffle 71 can be pulled out upward; rotate the sealing cover 8 upward to put the dry ice into the storage chamber 2 52 through the hole at the top of the storage chamber 2 52.

[0108] It is worth noting that a battery is fixedly installed in the vehicle body 1, and the battery is electrically connected to the hydraulic cylinder 25, the water pump 6, the motor 1 31 and the motor 2 44, ensuring that the battery can provide power to the hydraulic cylinder 25, the water pump 6, the motor 1 31 and the motor 2 44, ensuring that the overall device can operate normally;

[0109] It is worth noting that when the limit plate 1 21, the limit plate 22, the rotating column 23 and the top of the digging block 24 are located at the lowest position in the movable groove 11, the lowest positions of the plow 1 211, the plow 221 and the crushing knife 231 are all flush with the bottom of the digging block 24, and at the same time, the bottom of the driving block 241 is flush with the bottom of the roller 41.

[0110] Working principle: personnel put appropriate amount of water and dry ice into storage chamber 1 51 and storage chamber 2 52 respectively, then personnel start hydraulic cylinder 25, the output shaft of hydraulic cylinder 25 drives connecting plate 2 to move downward, connecting plate 2 drives limiting plate 1 21, limiting plate 22, rotating column 23 and several crushing knives 231 in limiting frame 3, and digging block 24 to move downward in movable groove 11 and penetrate into the ground.

[0111] At the same time, the motor 2 44 is started, the output shaft of the motor 2 44 drives the gear 4 43 to rotate, and the gear 43 drives the gear 3 42 to rotate, and the gear 3 42 drives one of the rotating shafts 4 to rotate, and one of the rotating shafts 4 drives the corresponding two rollers 41 to roll on the ground, so that the whole device can move forward on the ground.

[0112] The vehicle body 1 moves forward to drive the limiting plate 1 21, the limiting plate 22, the rotating column 23 and the digging block 24 to move forward together. At the same time, the limiting plate 1 21 and the limiting plate 22 respectively drive the plurality of plows 1 211 and the plurality of plows 221 to turn the soil on the ground.

[0113] At the same time, the motor 1 31 is started, and the output shaft of the motor 1 31 drives the gear 2 32 to rotate, and the gear 2 32 drives the gear 1 232 to rotate, and the gear 1 232 drives the rotating column 23 to rotate, and then the rotating rotating column 23 drives the plurality of crushing knives 231 to rotate and cut and crush the turned over soil. At this time, the excavated fireproof ditch has been formed, and the digging block 24 has also entered the fireproof ditch, and the two driving blocks 241 are attached to the ground. The crushed soil is squeezed by the advancing digging block 24 and moves upward in the fireproof ditch until it is located at the top of the fireproof ditch and enters the two driving blocks 241. Under the driving action of the driving block 241, the soil can be dispersed to a farther position to avoid affecting the rolling of the roller 41 on the ground. Now there is no crushed soil in the fireproof ditch;

[0114] While the plurality of plows 1 211 and the plurality of plows 221 are turning the soil on the ground, the water pump 6 is started, and the water suction end of the water pump 6 can absorb the water in the storage chamber 1 51 and transport it to the water distribution pipe 61. Under the action of the water pressure, the water in the water distribution pipe 61 is sprayed out as atomized liquid through the plurality of spray pipes 62 and falls on the turned soil and broken soil, so that the soil is wetted, and the wetted soil is ensured to be dispersed on both sides of the fireproof ditch by the two soil-driving blocks 241 to form the first layer of fireproof barrier;

[0115] Afterwards, the personnel can open the faucet 63 so that the water in the water distribution pipe 61 falls into the fireproof ditch through the faucet 63, and draw out the baffle 71 in the discharge pipe 7 upward, so that the dry ice in the storage chamber 2 52 is also discharged into the fireproof ditch through the two discharge pipes 7, so that the dry ice reacts with water to generate carbon dioxide gas. The density of carbon dioxide gas is greater than that of air. Therefore, a large amount of carbon dioxide gas will still be concentrated in the fireproof ditch, thereby forming a second layer of fireproof barrier.

[0116] The embodiments of the present application are described above in conjunction with the accompanying drawings. In the absence of conflict, the embodiments in the present application and the features in the embodiments can be combined with each other. The present application is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive.
