Description

Technical Field

[0001] This invention belongs to the technical field of water tanker fire trucks, specifically a forest water tanker fire truck. Background Technology

[0002] Forest water tanker fire trucks are core specialized equipment for fighting fires, clearing embers, and establishing firebreaks in mountainous forest areas. They primarily rely on the water stored in the onboard tank to provide self-sufficient water supply in the field. Compared to urban firefighting scenarios, forest operations present complex conditions such as narrow roads, steep slopes and sharp bends, bumpy road conditions, and numerous impurities in natural water sources. Currently, conventional forest fire truck tanks generally use a uniform aperture baffle structure, which can only achieve basic water buffering functions and has a limited flow stabilization effect. When vehicles travel on slopes, make sharp turns, or bumpy roads in forest areas, the water inside the tank is prone to violent lateral surges. The water mass at the bottom of the tank is concentrated, and the overturning moment is large, which can easily create unilateral eccentric loads. Conventional baffles cannot achieve peak water flow diversion, and the water in the entire tank shakes synchronously, which greatly aggravates the vehicle's tilt and can easily cause the vehicle to veer off course, skid, or even fall off a cliff and overturn, greatly reducing the driving safety in complex mountain road conditions. At the same time, the existing tank cannot differentiate and suppress the water sloshing at the front and rear sections. The longitudinal and lateral surges are prone to superimposed resonance, which impacts the tank welds and installation structure over a long period of time, causing fatigue damage and leakage failure of components, and shortening the service life of the equipment. On the other hand, forest fire fighting operations often rely on natural water sources such as mountain streams, ponds, and outdoor reservoirs. These water bodies carry a large amount of silt, humus, and debris. Existing tanks lack specific sedimentation, filtration, and anti-secondary disturbance structures, making it easy for impurities to accumulate in the dead corners at the bottom of the tank, which are difficult to clean thoroughly through conventional sewage discharge. When operating at low liquid levels or when the water is turbulent, the deposited impurities can be stirred up again and mixed into the water supply pipeline, causing wear on the pump impeller and blockage of the filter screen and nozzles. This directly leads to problems such as unstable water pressure, insufficient range, and atomization failure, interrupting fire fighting operations. In addition, the deposited humus and silt can corrode the anti-corrosion layer on the inner wall of the tank, causing the tank to rust and leak. The accumulation of impurities can also occupy the effective water storage volume, reducing the vehicle's self-sufficient fire fighting capability. Summary of the Invention

A flow channel is provided inside the longitudinal wave deflector, with one side opening located on the side wall of the flow hole on the longitudinal wave deflector and its top opening located at the top of the longitudinal wave deflector. A flow limiting plate is slidably connected to the flow channel via a spring, with one end of the flow limiting plate extending into the longitudinal wave deflector and the other end located in the flow hole of the longitudinal wave deflector.

The portion of the pushing plate away from the flow limiting plate contacts the transverse wave deflector.

[0006] Preferably, a flow guide plate is provided in the middle of the flow guide groove, and the two sides of the flow guide plate are inclined towards the top of the center. Inclined grooves are evenly distributed on two symmetrical side walls of the flow guide groove and face the top.

The two sides of the diversion plate are in contact with the inclined plates.

[0008] Preferably, the inclined groove opening is provided with a filter screen, and a rinsing tank is provided on one side of the inclined plate.

[0014] The beneficial effects of this invention are as follows: 1. The forest water tanker fire truck of the present invention, while the cleaning plate scrapes the inner wall of the tank and moves along the inner wall of the tank, a displacement sensor installed between the cleaning plate and the transverse baffle plate indirectly identifies the structural deformation of the tank by detecting the sliding distance of the cleaning plate on the transverse baffle plate.

[0015] 2. The forest water tanker fire truck of the present invention generates a lateral surge inside the tank when the fire truck turns or performs other operations. The stored water impacts the longitudinal baffle plate. Personnel can start and control the rotating rod to rotate, and the lateral baffle plate moves back and forth slowly. This causes the stored water flowing towards the longitudinal baffle plate to be pushed by the lateral baffle plate, reducing the force of the stored water impacting the longitudinal baffle plate vertically, reducing the force generated by the lateral surge of stored water, and improving the stability of the fire truck when turning during rapid maneuvers.

Detailed Implementation

[0018] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0019] Example 1: To effectively solve the above problems, see the attached diagram in the instruction manual. Figure 1-9 As shown, a forest water tanker fire truck includes an off-road chassis unit, a tank body 1, a fire pump unit, a spraying operation unit, and an auxiliary control unit. The tank body 1 includes a sedimentation tank 11, a maintenance manhole, an interface valve group module, and a monitoring module. The off-road chassis unit provides four-wheel drive off-road capability, adaptable to steep slopes and rough roads in forests. The sedimentation tank 11 of the tank body 1 collects silt and sand, the maintenance manhole facilitates dredging and maintenance, the interface valve group is responsible for water injection, sewage discharge, and water supply, and the monitoring module displays the liquid level in real time. The fire pump unit realizes water intake and pressurization for water supply. The spraying operation unit completes different modes of fire extinguishing through water cannons and water guns. The auxiliary control unit centrally manages the pump, water cannon, and liquid level, and coordinates the joint operation of each unit. Also includes: A rotating rod 12 is installed inside the tank body 1 and is located below the maintenance manhole. One end of the rotating rod 12 extends out of the side wall of one end of the tank body 1 and is connected to the drive component 13 on the fire truck. Both ends of the rotating rod 12 are rotatably connected to the side walls of both ends of the tank body 1. The rotating rod 12 is provided with a spiral groove 14 and a rotating ring 15 is sleeved on the rotating rod 12. The inner side of the rotating ring 15 extends into the spiral groove 14. The tank body 1 is provided with a longitudinal baffle plate 16 and a transverse baffle plate 17. The transverse baffle plate 17 is slidably connected to the inner wall of the tank body 1, and its top is rotatably connected to the rotating ring 15. A telescopic rod 18 is provided on one side of the transverse wave deflector 17 and is located between adjacent transverse wave deflectors 17. The end of the telescopic rod 18 is slidably connected to a vertical locking block 19 by a spring. The adjacent transverse wave deflectors 17 are provided with corresponding slots 2. Pressure sensors are distributed on the sides of the longitudinal wave deflector 16 and the transverse wave deflector 17. A cleaning plate 21 is slidably connected to the edge of the transverse wave deflector 17 by a spring. The cleaning plate 21 is distributed around the center of the transverse wave deflector 17, and a displacement sensor is provided between the cleaning plate 21 and the transverse wave deflector 17. The drive component 13 is a conventional motor, driven by the rotating rod 12 through a conventional transmission connection. The two ends of the longitudinal baffle 16 contact the two ends of the tank 1, and the two ends of the transverse baffle 17 contact the arc-shaped sidewall of the tank 1, sliding evenly on the longitudinal baffle 16. A locking block 19 is inserted into the locking slot 2, and the surface of the locking block 19 contacting the locking slot 2 is inclined, allowing the locking block 19 to disengage under excessive force. Pressure sensors on the longitudinal baffle 16 monitor the transverse surging force of the water in the tank 1, and pressure sensors on the transverse baffle 17 monitor the longitudinal surging force of the water in the tank 1. Displacement sensors monitor the displacement between the cleaning plate 21 and the transverse baffle 17, used for... The deformation of the side wall of tank 1 is monitored; the longitudinal baffle 16 and the transverse baffle 17 have flow holes for water to pass through, so that water can flow through the longitudinal baffle 16 and the transverse baffle 17 and keep the liquid level of the water in tank 1 flat; the rotating ring 15 is fixedly installed on the transverse baffle 17. When the rotating rod 12 rotates, the rotating rod 12 drives the transverse baffle 17 to rotate through the spiral groove 14 and the rotating ring 15. However, the transverse baffle 17 is restricted by the side wall of tank 1 and cannot rotate. Since the inner side of the rotating ring 15 extends into the spiral groove 14, the rotating ring 15 is guided by the spiral groove 14 and the rotational motion is converted into linear motion, similar to the reciprocating motion of a slider driven by a lead screw. Specific workflow: During the water intake and discharge process, the drive component 13 drives the rotating rod 12 to rotate. The rotating ring 15 is restricted by the transverse baffle plate 17, so that the rotating ring 15 drives the transverse baffle plate 17 to move from one end of the tank 1 to the other end. The movement of the first transverse baffle plate 17 drives the telescopic rod 18 to move. The telescopic rod 18 drives the second transverse baffle plate 17 to move through the connection of the locking block 19 and the locking groove 2. This continues until all the transverse baffle plates 17 move to one end of the tank 1. The contact part between the inner side of the transverse baffle plate 17 and the longitudinal baffle plate 16 scrapes the mud, sand, humus and other impurities attached to the surface of the longitudinal baffle plate 16 and settles them to the sedimentation tank 11 at the bottom. The outer side of the transverse baffle plate 17 is scraped by the cleaning plate 21 connected by the spring to scrape the inner wall of the tank 1, cleaning the inner wall of the tank 1 and improving the cleanliness of the inner wall of the tank 1. Furthermore, while the cleaning plate 21 scrapes the inner wall of the tank 1, it moves along the inner wall of the tank 1. A displacement sensor installed between the cleaning plate 21 and the transverse baffle plate 17 indirectly identifies structural deformation of the tank 1 by detecting the sliding distance of the cleaning plate 21 on the transverse baffle plate 17: when the tank 1 experiences negative pressure collapse or corrosion dents, the tank wall deforms inward, pushing the cleaning plate 21 inward. The displacement sensor detects that the distance between the cleaning plate and the transverse baffle plate 17 decreases accordingly, and the value of the inward deformation of the tank wall is calculated based on the reduction. When the tank 1 experiences... When overpressure bulges, the tank wall deforms outward, and the cleaning plate 21 extends outward under the action of the spring. The displacement sensor detects that the distance between the cleaning plate 21 and the transverse baffle plate 17 increases accordingly. Based on the increase, the value of the outward deformation of the tank wall is calculated, thereby realizing the online identification of hidden structural damage such as bulging, collapse, and thinning of the tank body 1. When the fire truck is resupplying or carrying out other operations in the middle of the operation, it ensures that the deformation problem of the tank body 1 is detected in time, avoiding the situation that affects subsequent operations, improving the status control of the tank body 1, so as to respond in a timely manner. When the fire truck is dispatched, the water level in tank 1 is normally between 90% and 95%, with the liquid level close to the top of the tank. The water sloshing amplitude is small, and the driving stability is better than that of a half-tank truck. However, the total weight of the vehicle is relatively large, and the surge force in tank 1 is increased. Therefore, during longitudinal surges, the water impacts the transverse baffles 17 from front to back. Adjacent transverse baffles 17 are connected by a spring-loaded telescopic rod 18. When the transverse baffles 17 are impacted forward by the water, the first transverse baffle 17 is fixed by the limit at one end of tank 1 and the locking of the rotating rod 12. The second transverse baffle 17 drives the telescopic rod 18 to squeeze the third transverse baffle 17. The telescopic rod 18 compresses the internal spring, which reduces the forward impact of the water, reduces the surge force, reduces the braking inertia of the fire truck, and improves the stability of the fire truck during rapid maneuvering. Water impacts the transverse baffle 17 backwards. The first transverse baffle 17 is fixed in position, while the second is further away from the first, increasing the distance between them and lengthening the telescopic rod 18. The telescopic rod 18 lengthens the internal spring, reducing the surge force and decreasing the fire truck's starting or uphill inertia, thereby improving the stability of the fire truck's rapid maneuverability. If the telescopic rod 18 is stretched too long, the locking block 19 is pulled out of the locking groove 2, preventing the telescopic rod 18 from breaking or the transverse baffle 17 from being stretched and deformed, maintaining the integrity of the transverse baffle 17 and improving its effectiveness. After the locking block 19 is released from the locking groove 2, the transverse baffles 17 can be moved closer together, allowing the locking block 19 to re-insert into the locking groove 2, completing the reset. When the fire truck turns or performs other operations, a lateral surge is generated inside the tank 1, and the stored water impacts the longitudinal baffle 16. Personnel can start and control the rotating rod 12 to rotate, and the lateral baffle 17 moves back and forth slowly, so that the stored water flowing towards the longitudinal baffle 16 is pushed by the lateral baffle 17, reducing the force of the stored water vertically impacting the longitudinal baffle 16, reducing the force generated by the lateral surge of stored water, and improving the stability of the fire truck when turning during rapid maneuvers. Furthermore, when the longitudinal baffle 16 and the transverse baffle 17 are impacted by stored water, the pressure sensors on both baffles 16 and 17 can promptly monitor the specific impact force values ​​within the tank 1. For example, when turning, the fire truck needs to brake and turn. By monitoring which baffle 16 or 17 experiences a greater impact force, the pressure sensors detect that the impact force on the longitudinal baffle 16 is about to exceed the safe range. If the impact force on the longitudinal baffle 16 is about to exceed the safe range, the transverse baffle 17 will be activated to move and reduce the transverse surge. If the transverse baffle 17 experiences an excessive impact force, personnel can indirectly reduce the longitudinal surge by gradually accelerating and lightly braking. The springs inside the telescopic rod 18 can be damping springs to avoid the repeated expansion and contraction of ordinary springs after being compressed, which could actually cause water surges.

[0020] Example 2: Based on Embodiment 1, a buffer plate 22 is slidably connected to one side of the transverse wave deflector 17 via a spring, and a wavy surface is provided on one side of the longitudinal wave deflector 16, with the wavy surface arranged longitudinally. A portion of the buffer plate 22 extends into the wavy surface of the longitudinal wave deflector 16, while the other portion contacts a flat surface. The flow holes on the longitudinal wave deflector 16 and the transverse wave deflector 17 are rectangular. A flow channel 23 is provided inside the longitudinal wave deflector 16, with one opening of the flow channel 23 located on the sidewall of the flow hole on the longitudinal wave deflector 16, and its top opening located at... A flow-limiting plate 24 is slidably connected to the top of the longitudinal wave-blocking plate 16 and inside the flow-draining groove 23 via a spring. One end of the flow-limiting plate 24 extends into the longitudinal wave-blocking plate 16, and the other end is located in the flow-through hole of the longitudinal wave-blocking plate 16. A pushing plate 25 is hinged to the top of the flow-limiting plate 24 via a torsion spring. The pushing plate 25 slides inside the top of the flow-draining groove 23. The part of the pushing plate 25 away from the flow-limiting plate 24 contacts the transverse wave-blocking plate 17. The part of the pushing plate 25 away from the flow-limiting plate 24 contacts the first transverse wave-blocking plate 17, that is, the transverse wave-blocking plate 17 fixed by the rotating rod 12. A flow guide plate 26 is provided in the middle of the flow guide groove 23. The two sides of the flow guide plate 26 are set obliquely towards the top center. The two symmetrical side walls of the flow guide groove 23 are evenly distributed with inclined grooves 27 facing the top. The bottom of the diversion plate 26 is hinged to the bottom of the diversion groove 23 by a torsion spring, the top of the diversion plate 26 is slidably connected to the side wall of the diversion groove 23, the two sides of the diversion plate 26 are close to the inclined groove 27, the inner wall of the inclined groove 27 is composed of inclined pieces 28, and two inclined pieces 28 are distributed vertically to form the inclined groove 27. The inclined pieces 28 are hinged to the longitudinal wave deflector 16 by a torsion spring, and the inclined pieces 28 are unidirectionally swinging. The two sides of the diversion plate 26 contact the inclined pieces 28. The inclined groove 27 has a filter screen 29 at its opening, and a rinsing tank 3 is provided on one side of the inclined plate 28. The rinsing tank 3 is located between the inclined plate 28 and the filter screen 29, and the rinsing hole on the rinsing tank 3 is aligned with the filter screen 29. Specific workflow: When the transverse wave deflector 17 is impacted by the longitudinal surge, the transverse wave deflector 17 drives the buffer plate 22 to move along the longitudinal wave deflector 16. One end of the buffer plate 22 extends into the wavy surface of the longitudinal wave deflector 16. Guided by the wavy surface, the buffer plate 22 repeatedly extends and retracts on the transverse wave deflector 17 during the movement. On the one hand, the friction between the buffer plate 22 and the wavy surface of the longitudinal wave deflector 16 forms continuous resistance to the movement of the transverse wave deflector 17, preventing the transverse wave deflector 17 from moving too fast after being impacted and causing impacts between them, thereby improving the buffering effect of the transverse wave deflector 17 and improving the stability of the fire truck's rapid maneuverability. Furthermore, the buffer plate 22 controls the transverse baffle plate 17 to slow down its movement speed, which can slow down the movement speed of the cleaning plate 21 along the side wall of the tank 1. This avoids the situation where the movement speed is too fast and the deformed parts of the tank 1 are not detected, resulting in the tank 1 being impacted and deformed in time, which may affect subsequent operations and thus improve the effectiveness of the fire truck. Moreover, during the movement of the buffer plate 22, repeated extension and retraction slightly collide with the longitudinal baffle plate 16, causing the longitudinal baffle plate 16 to resonate, loosening the impurities attached to the longitudinal baffle plate 16, improving the cleanliness of the longitudinal baffle plate 16, and thus improving the cleanliness of the inside of the tank 1. If water needs to be replenished during the operation, and the return trip involves navigating continuous sharp bends in mountain roads, the traditional fixed-diameter flow orifice will not provide sufficient damping at low liquid levels, causing severe lateral sloshing of the water and increasing vehicle tilt. Therefore, when the water level is low, personnel can rotate rod 12 to move the first lateral baffle 17. The lateral baffle 17 contacts the top of the push plate 25 and moves it. At this time, the push plate 25 and the flow-limiting plate 24 can move freely, and the force generated by the torsion spring of the push plate 25 drives the force generated by the return spring on the flow-limiting plate 24, causing the push plate 25 to move the flow-limiting plate 24 into the flow orifice, thus limiting the flow. Plate 24 reduces the flow cross-sectional area of ​​the flow passage, slowing down the lateral swaying of water at low liquid levels in tank 1, making the fire truck more stable when driving on mountain roads at low liquid levels, reducing the risk of rollover, and improving the stability of the fire truck. When the water source is insufficient, the transverse baffle 17 moves in the opposite direction, and the reset spring on the flow limiting plate 24 drives the flow limiting plate 24 and the push plate 25 to return to their original positions. The flow limiting plate 24 restores the flow cross-sectional area of ​​the flow passage on the longitudinal baffle 16, forming an adaptive adjustment state with low flow damping when the water level in tank 1 is high and low, further improving the stability of the fire truck. When the transverse baffles 17 retract and approach each other, the flow-limiting plate 24 of the transverse baffle 17 moves to its limit position, and the pushing plate 25 continues to be pressed and swings. The transverse baffle 17 passes over the pushing plate 25. After the pushing plate 25 is no longer compressed, it swings back to its original position through the torsion spring, and the flow-limiting plate 24 moves back to its original position through the spring. When the transverse baffle 17 retracts and unfolds to its original position, the transverse baffle 17 passes over the pushing plate 25 again. The pushing plate 25 is also pressed and swings, allowing the transverse baffle 17 to pass over smoothly. When the vehicle turns, the transverse baffle 17 can be used to temporarily reduce the flow of the flow through the flow-limiting plate 24 by pushing the plate 25. Most of the water impacts the longitudinal baffle 16, and a small part impacts the side wall of the tank 1. Since the longitudinal baffle 16 is closer to the center of the vehicle than the side wall of the tank 1, the longitudinal baffle 16 shares the surge of the side wall of the tank 1, reducing the risk of the water flow center of gravity shifting and causing the vehicle to overturn, thereby improving the stability of the vehicle. When the vehicle is parked on an inclined surface for operation, the vehicle can control the transverse baffle 17 to close the flow hole of the longitudinal baffle 16 in advance on a flat surface, so that the longitudinal baffle 16 divides the water into multiple parts, avoiding the situation where the vehicle is parked on an inclined surface for operation needs, and all the water is pressed on the side wall of the tank 1, causing excessive pressure on the ground on one side of the vehicle, resulting in ground collapse or even tilting. When the stored water impacts the longitudinal baffle plate 16, part of it flows through the flow holes, and the other part enters the diversion channel 23 through the inclined channel 27. The inclined channel 27 is inclined to guide the stored water, guiding it to flow obliquely upward to contact the diversion plate 26. Since the diversion plate 26 is inclined to the top of the center on both sides, the stored water that originally flowed obliquely upward to contact the diversion plate 26 is guided again and propelled by the flow of subsequent water. This allows part of the stored water to be guided by the diversion plate 26 and sprayed out from the top of the diversion channel 23. The horizontal flow of the stored water is transformed into a gradually upward spray force through force line guidance, dispersing the impact force of the horizontal surge of the stored water, reducing the risk of lateral tilting of the horizontal surge, further improving the stability of the fire truck and the mobility of the vehicle during fire fighting. Furthermore, when a lateral surge impacts one side of the diversion plate 26, the diversion plate 26 is compressed and tilted. Through the force generated by the torsion spring, the impact of the lateral surge is reduced, while the tilting amplitude of the diversion plate 26 is increased, thereby increasing the diversion effect of the diversion plate 26 on the lateral surge and improving the buffering effect. This improves the stability of the fire truck and the mobility of the vehicle during firefighting. Furthermore, when the guide plate 26 swings, it contacts the inclined plate 28 in the inclined groove 27. The inclined plate 28 is squeezed by the guide plate 26 and swings closer to the filter screen 29, slowing down the swing speed of the guide plate 26 and preventing excessive vibration caused by rapid swing. At the same time, during the swing of the inclined plate 28 and the filter screen 29, the flushing tank 3 sandwiched in the middle is squeezed. The flushing hole of the flushing tank 3 is aligned with the filter screen 29 and flushes water in the opposite direction. The lateral surge contacts the water-facing side of the guide plate 26, while the flushing tank 3 flushes the filter screen 29 on the water-repellent side of the guide plate 26. The filter screen 29 intercepts impurities in the stored water, preventing impurities from being lifted and suspended and sucked into the water spray gun and other components, which could cause blockage. The flushing tank 3 flushes the filter screen 29, washing away the intercepted impurities to the bottom of the tank, ensuring the fluidity and filtration capacity of the filter screen 29, further improving the cleanliness of the stored water, and preventing impurities in the forest water source from aggravating the impact on the water spray gun and other components.

[0021] Example 3: Based on Embodiment 2, the bottom of the transverse baffle plate 17 is inclined and faces the sedimentation tank 11, and the transverse baffle plate 17 is provided with a squeezing tank 31, one side of the squeezing tank 31 contacts the longitudinal baffle plate 16. One side of the buffer plate 22 is flat. The squeezing tank 31 is located between the flat part of the buffer plate 22 and the transverse baffle plate 17. The suction end of the squeezing tank 31 faces the filter screen 29, and the discharge end faces the bottom. Both the squeezing tank 31 and the rinsing tank 3 are conventional small water storage tanks that are resistant to high pressure. The outer shell of the water storage tank resists the pressure generated by the stored water and will not collapse. One end of the tank is a sealed and slidingly connected piston, which facilitates the suction and discharge of water by the squeezing tank 31 and the rinsing tank 3. The tank body 1 has a telescopic tube 32 on one side wall. One end of the telescopic tube 32 faces the transverse baffle 17 and has an outlet, while the other end extends out of one end of the tank body 1 and has a feeding port. Specific workflow: When it is necessary to clean the sedimentation tank 11, control the movement of the transverse baffle 17. The bottom slope of the transverse baffle 17 guides some water into the sedimentation tank 11. The water flows through the slope and washes the sedimentation tank 11 at the same time. The slag discharge port at the bottom of the tank 1 opens, and a small amount of water washes the sedimentation tank 11 and carries impurities into the slag discharge port for discharge. This allows the sedimentation tank 11 and impurities to be cleaned at any time during water replenishment and other static conditions, avoiding the situation where water sloshing during operation causes impurities to be stirred up and reduce cleanliness. By setting up the squeezing tank 31, the buffer plate 22 moves back and forth over the wave surface of the longitudinal wave deflector 16, while moving past the filter screen 29. The buffer plate 22 and the transverse wave deflector 17 compress the squeezing tank 31. The squeezing tank 31 pushes the water inside to the bottom and slowly enters the sedimentation tank 11, which facilitates the collection of impurities filtered on the filter screen 29. The impurities are continuously gathered in the sedimentation tank 11 to prevent them from flowing around, thereby improving the cleanliness of the water. Forest fires are complex and require temporary responses to different scenarios. For example, in the case of surface fires and smoldering and reignition in the humus layer, water-based wetting and penetrating agents are added to enhance water penetration, moisture retention, and flame retardancy. In the case of high-intensity crown fires and easily flashover fires, foam extinguishing agents are added to form a heat-insulating water film and suppress the fire. Therefore, when adding the agent, personnel add it through the filling port. The agent enters the telescopic pipe 32, and the transverse baffle 17 moves to squeeze the telescopic pipe 32 and then releases it. The telescopic pipe 32 absorbs the water and mixes with the agent. Then, the transverse baffle 17 squeezes the telescopic pipe 32 again, and the outlet of the telescopic pipe 32 opens to spray the mixed agent into the water. Personnel can control the transverse baffle 17 to move back and forth to stir the water. The mixture is automatically mixed in advance before the vehicle arrives at the work site, improving the fire truck's operational effectiveness and thus enhancing its practicality.

[0022] Example 4: Based on Embodiment 3, one end of the telescopic tube 32 is provided with an extension tube 33, and the extension tube 33 is made of a tough material. The extension tube 33 is connected to the telescopic tube 32 and has holes evenly distributed. A wave-damping curtain 34 is rolled up above the telescopic tube 32, and one end of the wave-damping curtain 34 is connected to one side of the transverse wave-damping plate 17. The wave-damping curtain 34 is distributed vertically inside the tank body 1. Specific workflow: By setting up an extension pipe 33, when it is necessary to add medicine, the telescopic pipe 32 is squeezed to spray the mixed medicine into the extension pipe 33. The extension pipe 33 sprays the mixed medicine evenly into the water in various parts of the tank 1 through evenly distributed holes, thereby improving the mixing efficiency. In addition, when it is necessary to discharge slag, the personnel open the valves of the telescopic pipe 32 and the feeding port to connect the water pump. The water pump removes the impurities in the sedimentation tank 11, thereby improving the convenience of cleaning the tank 1. By setting up a wave-damping curtain 34, which is a conventional lightweight net covering the liquid surface, when the transverse wave-damping plate 17 moves from the end of the tank 1 to the beginning and returns to the initial static position, the transverse wave-damping plate 17 pulls the wave-damping curtain 34 to unfold, covering the water surface. When the liquid level is high, the upper wave-damping curtain 34 covers the high liquid level surface, and the lower wave-damping curtain 34 is submerged in the water. When the liquid level is low, the upper wave-damping curtain 34 is suspended above, and the lower wave-damping curtain 34 covers the low liquid level surface, cutting the entire continuous water surface into a large number of small areas, restricting the surface water from sliding left and right and back and forth over a large range, preventing the formation of concentrated giant waves, weakening the lateral and longitudinal swell kinetic energy, reducing the eccentric weight on one side, reducing the risk of rollover, and improving the stability of the vehicle during rapid maneuvering.
