A multi-purpose forest fire water tank truck

Abstract

This invention discloses a multi-purpose forest fire fighting water tanker, belonging to the field of forest fire fighting technology. Through a pressure-down mechanism and a support mechanism, when a fire occurs and long-distance water collection is needed, the vehicle, with the aid of its off-road capabilities, selects a relatively flat and stable section of road to park and deploy multiple support structures as nodes. This guides the water pipes around terrain unsuitable for water transport, ensuring smooth water delivery and expanding the applicability of the water collection system. Based on the distance between the water source and the fire site, multiple water pipes are connected through multiple support structures at their ends, forming a water collection channel composed of multiple water pipes and support structures. This improves water collection efficiency and provides reliable water support for forest fire fighting. By securely binding the water pipes to the support structures using ropes, clips, etc., wear and tear caused by displacement due to external forces can be prevented.

Description

Technical Field

[0001] This invention relates to the field of forest fire fighting technology, and in particular to a multi-purpose forest fire fighting water tanker. Background Technology

[0002] Forest fire trucks are special vehicles specifically designed for fighting forest fires. Unlike traditional urban fire trucks, forest fire trucks are usually equipped with the ability to pump water from nearby water sources over long distances. By using multiple pumps to pressurize the water in relays, water is drawn from natural water sources such as rivers and lakes several kilometers away and transported to the fire site. This system not only improves the efficiency of firefighting but also greatly reduces the risks and labor intensity for firefighters in the process of finding and transporting water sources. However, in the actual water intake process, the terrain around natural water sources is usually complex, with dense vegetation and irregular rock distribution. These obstacles increase the difficulty of laying water pipes, making it difficult for water pipes to extend along the ideal path. In addition, the vibration generated by the operation of water pumps and the impact generated by the flow of water in the pipes can easily cause the water pipes to shift. Friction and collision with obstacles can lead to damage to the pipes, causing water leakage and affecting the stable delivery of water. Summary of the Invention

[0003] The purpose of this invention is to address the problem that in actual water intake processes, the surrounding terrain of natural water sources is usually complex, with dense vegetation and irregular rock distribution. These obstacles increase the difficulty of laying water pipes, making it difficult for water pipes to extend along the ideal path. Furthermore, the vibration generated by the operation of the water pump and the impact generated by the flow of water in the pipes can easily cause the water pipes to shift. Friction and collision with obstacles can also lead to pipe damage, causing water leakage and affecting the stable delivery of water. Therefore, a multi-purpose forest fire fighting water tanker is proposed.

[0004] To achieve the above objectives, the present invention employs the following technology: a multi-purpose forest fire-fighting water tanker truck. The vehicle includes a forest fire truck body, which includes a truck head and a cargo box mounted on the truck head. The cargo box is fitted with a frame through a mounting chamber with an opening at the bottom. A pressing mechanism is mounted on the frame. The pressing mechanism includes an open base set inside the frame. A placement cylinder is mounted on the base through two mounting brackets. There is a pre-set interval between the base and the placement cylinder. In addition, a hydraulic telescopic rod installed on the frame and a pressing member connected to the output end of the hydraulic telescopic rod, wherein the hydraulic telescopic rod pushes the pressing member into the placement cylinder; The placement cylinder is filled with a support mechanism, which includes a support plate with an outer diameter the same as the inner diameter of the placement cylinder. The support plate is equipped with a frame for fixing water pipes and spiral ground nails inserted into the ground. The frame is pushed out of the placement cylinder and the installation chamber by a pressing component, and the frame is inserted into the forest ground through the spiral ground nails.

[0005] Further description of a multi-purpose forest fire fighting water tanker as described above: The inner wall of the placement cylinder is provided with a guide rail, which includes a spiral rotating track that passes through the bottom of the placement cylinder. The top of the frame is fitted with a guide member embedded in a rotating track via an abutment. When the pressing member pushes the abutment to move, the rotating track, in conjunction with the guide member, drives the frame to rotate, causing the spiral ground stake to rotate and insert into the forest ground. The spiral ground stake is inserted when the guide member disengages from the rotating track.

[0006] Further description of a multi-purpose forest fire fighting water tanker as described above: The pressing component includes a slide table slidably disposed within the frame, and a pressing head is provided in the middle of the slide table, the outer diameter of the pressing head being the same as the inner diameter of the abutment part; The pressure head has an annular cavity with a depth equal to the maximum descent height of the pressure head, and a limiting cavity that cooperates with the mounting bracket is provided in the cavity. When the pressure head is inserted into the placement cylinder and pushes the contact part, the mounting bracket and the placement cylinder are respectively embedded in the limiting cavity and the receiving cavity.

[0007] Further description of a multi-purpose forest fire fighting water tanker as described above: The frame includes an annular frame connecting the support plate and the abutment part, and the annular frame has a cavity inside. On both sides of the cavity, there are interlocking arc-shaped frames through spring telescopic rods. A water supply pipe is opened in the middle of each of the two arc-shaped frames.

[0008] Further description of a multi-purpose forest fire fighting water tanker as described above: The guide rail also includes a drop rail located at the upper end of the rotating rail and extending to the top of the placement cylinder. The guide member slides to the rotating rail via the drop rail. A limit groove is provided in the middle section of the drop rail, and a locking mechanism for fixing the position of the guide member is rotatably installed in the limit groove.

[0009] Further description of a multi-purpose forest fire fighting water tanker as described above: The locking mechanism includes a first rotating shaft rotatably disposed inside the placement cylinder. The end of the first rotating shaft is provided with a limiting member that cooperates with the inner wall of the limiting groove. The limiting member is configured as an arc shape with the inner wall fitting against the guide member. When the arc opening faces upward, it restricts the position of the guide member. The other end of the first rotating shaft is provided with a driving component that drives the limiting component to rotate. When the arc-shaped opening rotates to face downwards, the restriction on the position of the guide component is released.

[0010] Further description of a multi-purpose forest fire fighting water tanker as described above: The placement cylinder slides to below the pressure head via a feeding mechanism located at the bottom of the frame; The feeding mechanism includes a chassis mounted on a frame, with a limiting ring at the front end of the chassis having the same inner diameter as the placement cylinder, and the chassis being slidably connected to the base via a slide rail. The chassis is also equipped with an electric push rod, the output end of which is connected to the base.

[0011] Further description of a multi-purpose forest fire fighting water tanker as described above: The placement cylinder is provided with a mounting platform, which slides down the pressure head along with the placement cylinder and drives the first rotating shaft to rotate through a driving component. The driving component includes a second rotating shaft rotatably disposed within the mounting platform. A second bevel gear and a driven gear are respectively mounted at both ends of the second rotating shaft. The first rotating shaft meshes with the second bevel gear through a first bevel gear mounted at the other end. The bottom of the pressure head is equipped with a rack that meshes with the driven gear.

[0012] Further description of a multi-purpose forest fire fighting water tanker as described above: The opening arc on the base matches the limiting ring, and when the base and the limiting ring are in contact, the placement cylinder coincides with the axis of the limiting ring and the pressure head.

[0013] One of the above technical solutions has the following advantages or beneficial effects: 1. Through the set-down mechanism and support mechanism, when a fire occurs and remote water intake is required, with the cooperation of the vehicle's off-road performance, a relatively flat and stable section of road is selected to park and set up multiple frames as nodes. This guides the water pipes around terrain unsuitable for water transport, ensuring smooth water delivery and expanding the applicable range of the water intake system. According to the distance between the water source and the fire site, multiple water pipes are respectively passed through multiple frames and connected to each other at the port to form a water intake channel composed of multiple water pipes and multiple frames, improving water intake efficiency and providing reliable water source support for forest fire fighting. After the water pipes are firmly bound to the frames by ropes, buckles and other means, wear problems caused by displacement due to external forces can be prevented. Setting the water pipe connection points close to the frames can also raise the connection points above the ground, further improving the protection of the water pipe interfaces, reducing the risk of water pipe leakage, and ensuring the stability of water intake. 2. Using the set guide rails, when the support mechanism needs to be filled, the guide is aligned with the falling track and inserted. After the abutment part is filled, the hydraulic telescopic rod is activated to drive the pressing part to press down. After the pressing part contacts the abutment part, it pushes the guide part to move along the falling track, so that the spiral ground nail is moved out of the placement cylinder first and puts it into contact with the Senda ground. As the pressing part continues to descend, the guide part slides from the falling track into the rotating track. Under the guidance of the rotating track, the guide part drives the frame to rotate, so that the frame drives the spiral ground nail to rotate and insert into the forest ground through the support plate. When the guide part disengages from the bottom of the rotating track, the spiral ground nail is fully inserted. The spiral insertion method increases the contact area between the spiral ground nail and the ground, improves its stability in the complex forest environment, and prevents the frame from moving, tilting and collapsing under vibration.

[0016] The following will describe in detail, with reference to the accompanying drawings, the technology of a multi-purpose forest fire-fighting water tanker according to the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0017] To address the challenges posed by complex terrain, dense vegetation, and irregularly distributed rocks surrounding natural water sources during actual water intake, which increase the difficulty of pipe laying and prevent pipes from following ideal paths, as well as the vibrations from pump operation and the impact of water flow within the pipes causing displacement, friction and collisions with obstacles leading to pipe damage, leaks, and disruptions to stable water delivery, this invention proposes a multi-purpose forest fire fighting water tanker. Figure 1 - Figure 21 As shown: The forest fire truck body 10 includes a truck head 11 and a cargo box 12 mounted on the truck head 11. The cargo box 12 is fitted with a frame 14 through a mounting compartment 13 with an opening at the bottom. like Figure 2 and Figure 3 As shown, a pressing mechanism 20 is installed on the frame 14. The pressing mechanism 20 includes an open base 21 set inside the frame 14. A placement cylinder 23 is installed on the base 21 by two mounting brackets 22. There is a preset gap between the base 21 and the placement cylinder 23. A guide rail 24 is provided on the inner wall of the placement cylinder 23. A hydraulic telescopic rod 25 is also installed on the frame 14. A pressing component 26 is connected to the output end of the hydraulic telescopic rod 25. By activating the hydraulic telescopic rod 25, the hydraulic telescopic rod 25 can push the pressing component 26 into the placement cylinder 23. like Figure 4 and Figure 5 As shown, the placement cylinder 23 is filled with a support mechanism 30. The support mechanism 30 includes a support plate 31 with an outer diameter the same as the inner diameter of the placement cylinder 23. A frame 32 for fixing water pipes and a spiral ground nail 33 inserted into the ground are installed on the support plate 31. The frame 32 is pushed out of the placement cylinder 23 and the installation chamber 13 by the pressing member 26. The frame 32 is inserted into the forest ground through the spiral ground nail 33. After fixing, the trolley 11 is started, so that the trolley 11 drives the frame 14 to move through the carriage 12 and the installation chamber 13. The separation from the frame 32 is completed through the opening at the bottom of the installation chamber 13 and the preset interval between the base 21 and the placement cylinder 23, so as to avoid spatial interference with the frame 32. When a fire occurs and water needs to be retrieved remotely, with the help of the off-road performance of the vehicle's front 11, a relatively flat and stable section of road is selected to park and multiple frames 32 are set up as nodes to guide the water pipes around terrain that is not suitable for water flow, ensuring smooth water delivery and expanding the applicable range of the water retrieval system. Based on the distance between the water source and the fire site, multiple water pipes are passed through multiple frames 32 and connected to each other at the ends to form a water intake channel composed of multiple water pipes and multiple frames 32, thereby improving water intake efficiency and providing reliable water source support for forest fire fighting. By securing the water pipes to the frame 32 with ropes, buckles, or other means, wear and tear caused by displacement due to external forces can be prevented. By placing the water pipe connections close to the frame 32, the connections can be raised above the ground, further enhancing protection of the water pipe interfaces, reducing the risk of water pipe leakage, and ensuring water intake stability. Preferred, such as Figure 7 As shown, the frame 32 includes an annular frame 321 connecting the support plate 31 and the abutment part 34. The annular frame 321 has a cavity inside. On both sides of the cavity, there are interlocking arc-shaped frames 322 provided by spring telescopic rods 323. The two arc-shaped frames 322 have holes through which the water supply pipe passes. By pushing with the spring telescopic rods 323, the two arc-shaped frames 322 can apply a holding force to the surface of the water pipe that passes through the middle of the annular frame 321, thereby achieving the effect of pre-fixing the water pipe before it is firmly bound.

[0018] like Figure 6 As shown, in order to further improve the fixing effect of the frame 32 after it is inserted into the forest ground, a guide rail 24 is provided on the inner wall of the placement cylinder 23. The guide rail 24 includes a spiral rotating track 241 that passes through the bottom of the placement cylinder 23. A falling track 242 that passes through to the top of the placement cylinder 23 is provided at the upper end of the rotating track 241. A guide member 35 that is embedded in the rotating track 241 is installed on the top of the frame 32 through the abutment part 34. When the support mechanism 30 needs to be filled, the guide 35 is aligned with the drop track 242 and inserted. After the abutment part 34 is filled, the hydraulic telescopic rod 25 is activated to drive the pressing part 26 to press down. After the pressing part 26 contacts the abutment part 34, it pushes the guide 35 to move along the drop track 242, so that the spiral ground nail 33 is moved out of the placement cylinder 23 first and fits against the Senda ground. As the pressing part 26 continues to descend, the guide 35 slides from the drop track 242 into the rotating track 241. Under the guidance of the rotating track 241, the guide 35 drives the frame 32 to rotate, so that the frame 32 drives the spiral ground nail 33 to rotate through the support plate 31 and insert it into the forest ground. When the guide 35 disengages from the bottom of the rotating track 241, the spiral ground nail 33 is fully inserted. The spiral insertion method increases the contact area between the spiral ground nail 33 and the ground, improves its stability in the complex forest environment, and prevents the frame 32 from moving, tilting and collapsing under vibration.

[0019] Furthermore, such as Figure 8 - Figure 10As shown, the pressing member 26 includes a slide table 261 slidably disposed in the frame 14, and a pressing head 262 is disposed in the middle of the slide table 261. The outer diameter of the pressing head 262 is the same as the inner diameter of the abutment part 34. An annular cavity 263 with a depth of the same as the maximum descent height of the pressing head 262 is opened in the pressing head 262. A limiting cavity 264 that cooperates with the mounting frame 22 is disposed in the cavity 263. When the pressing head 262 is inserted into the placement cylinder 23 and pushes the abutment part 34, the mounting frame 22 and the placement cylinder 23 are respectively embedded in the limiting cavity 264 and the cavity 263. This design avoids spatial interference between the pressing component 26 and the placement cylinder 23, allowing the pressing head 262 to be inserted into the placement cylinder 23 without obstruction and push the abutment part 34, thus improving the reliability of equipment operation. At the same time, the limiting cavity 264 limits the mounting frame 22, keeping the mounting frame 22 in a fixed position during the pressing process, reducing the shaking and displacement between components, thereby ensuring the stability of the placement cylinder 23 connected to the mounting frame 22 and the internal support mechanism 30. This allows the pressing component 26 to accurately transmit force to the abutment part 34, and the frame 32 to move out of the placement cylinder 23 and insert into the ground in a predetermined direction, thereby improving the accuracy of device operation.

[0020] To improve the speed and accuracy of pushing the support mechanism 30 below the pressure head 262, such as Figure 2 and Figure 18 As shown, the placement cylinder 23 slides to the bottom of the pressure head 262 via the feeding mechanism 50 provided at the bottom of the frame 14. The feeding mechanism 50 includes a chassis 51 provided on the frame 14. A limiting ring 52 with the same inner diameter as the placement cylinder 23 is provided at the front end of the chassis 51. The chassis 51 is slidably connected to the base 21 via a slide rail 53 provided at the top. An electric push rod 54 is also provided on the chassis 51. The output end of the electric push rod 54 is connected to the base 21. like Figure 19 - Figure 21 As shown, when the support mechanism 30 needs to be filled, the electric push rod 54 is activated to put it into a retracted state, pulling the placement cylinder 23 from directly below the pressure head 262 to the filling position. After the support mechanism 30 is filled into the placement cylinder 23, the electric push rod 54 is activated again to start extending it. The electric push rod 54 pushes the base 21 connected to the end to slide under the restriction of the slide rail 53. The opening arc on the base 21 matches the limiting ring 52. When the base 21 slides to the position where it fits against the limiting ring 52, the placement cylinder 23 coincides with the axis of the limiting ring 52 and the pressure head 262. At the same time, the limiting ring 52 restricts the position of the base 21 to prevent the base 21 from shifting or shaking. At this time, the hydraulic telescopic rod 25 is activated to push the lower pressing member 26 down.

[0021] like Figure 11 - Figure 17As shown, during the process of pushing the placement cylinder 23 from the filling position to directly below the pressure head 262, in order to prevent the guide 35 from sliding prematurely in the falling track 242 and the rotating track 241, a limiting groove 243 is opened in the middle section of the falling track 242, and a locking mechanism 40 for fixing the position of the guide 35 is rotatably arranged in the limiting groove 243. The locking mechanism 40 includes a first rotating shaft 41 rotatably arranged in the placement cylinder 23, and a limiting member 42 that cooperates with the inner wall of the limiting groove 243 is provided at the end of the first rotating shaft 41. The limiting member 42 is set as an arc shape with the inner wall fitting the guide 35, and the position of the guide 35 is restricted when the arc opening faces upward.

[0022] The other end of the first rotating shaft 41 is provided with a driving member 43 that drives the limiting member 42 to rotate. When the arc-shaped opening rotates to face downward, it releases the restriction on the position of the guide member 35. The placement cylinder 23 is provided with a mounting platform 231. The mounting platform 231 slides down the pressure head 262 along with the placement cylinder 23. The first rotating shaft 41 is driven to rotate by the driving member 43. The driving member 43 includes a second rotating shaft 432 that is rotatably disposed in the mounting platform 231. The two ends of the second rotating shaft 432 are respectively equipped with a second bevel gear 433 and a driven gear 434. The first rotating shaft 41 meshes with the second bevel gear 433 through the first bevel gear 431 installed at the other end. The bottom of the pressure head 262 is equipped with a rack 44 that meshes with the driven gear 434. With this design, when the placement cylinder 23 is in the filling position, the arc-shaped opening of the limiting member 42 faces upward. When the guide member 35 is inserted into the falling track 242, it enters the cavity formed by the combination of the limiting groove 243 and the limiting member 42, thereby achieving the purpose of limiting the position of the guide member 35 and preventing the support mechanism 30 from being accidentally displaced due to the movement of the guide member 35 during the filling process. After the support mechanism 30 is filled, as the base 21 slides toward the pressure head 262, the rack 44 installed at the bottom of the pressure head 262 contacts and meshes with the driven gear 434 set on the mounting platform 231. As the base 21 continues to slide, the rack 44 drives the second rotating shaft 432 to rotate through the driven gear 434. The second rotating shaft 432 drives the first bevel gear 431 to rotate through the second bevel gear 433. The first bevel gear 431 drives the limiting member 42 to rotate through the first rotating shaft 41 until the arc-shaped opening of the limiting member 42 faces downward. At this time, the restriction on the position of the guide member 35 is released, and the guide member 35 can slide in the falling track 242 and complete the subsequent fixing operation. After the support mechanism 30 is fixed, when the base 21 slides toward the filling position again, the limiting member 42 rotates again to the arc-shaped opening facing upward under the cooperation of the driving member 43 and the rack 44.

[0023] Working principle: The loading support mechanism, by activating the electric push rod 54 to put it into a retracted state, pulls the placement cylinder 23 from directly below the pressure head 262 to the loading position, and loads the support mechanism 30 into the placement cylinder 23; When the placement cylinder 23 is in the filling position, the arc-shaped opening of the limiting member 42 faces upward, and the guide member 35 enters the cavity formed by the combination of the limiting groove 243 and the limiting member 42 after being inserted into the falling track 242, thus restricting the position of the guide member 35. Start the electric push rod: Start the electric push rod 54 again to make it extend and push the end connected base 21 to slide under the restriction of the slide rail 53; when the base 21 slides to the position of being in contact with the limit ring 52, the placement cylinder 23 coincides with the axis of the limit ring 52 and the pressure head 262, and the limit ring 52 restricts the position of the base 21 to prevent it from shifting or shaking. During the sliding process of the base 21 toward the pressure head 262, the rack 44 at the bottom of the pressure head 262 contacts and meshes with the driven gear 434 on the mounting platform 231, driving the second rotating shaft 432 to rotate. The second rotating shaft 432 drives the first bevel gear 431 to rotate through the second bevel gear 433. The first bevel gear 431 drives the limiting member 42 to rotate through the first rotating shaft 41 until the arc-shaped opening of the limiting member 42 faces downward, releasing the restriction on the position of the guide member 35. Start the hydraulic telescopic rod 25, push the pressing part 26 down, and after the pressing head 262 of the pressing part 26 contacts the abutment part 34, push the guide part 35 to move along the falling track 242, so that the spiral ground nail 33 is the first to be moved out of the placement cylinder 23 and fits against the forest ground; As the pressure member 26 continues to descend, the guide member 35 slides from the falling track 242 into the rotating track 241. Under the guidance of the rotating track 241, the frame 32 rotates, causing the frame 32 to rotate through the support plate 31 and insert the spiral ground nail 33 into the forest ground. When the guide member 35 disengages from the bottom of the rotating track 241, the spiral ground nail 33 is fully inserted. After the fixing is completed, the locomotive 11 is started, so that the locomotive 11 drives the frame 14 to move through the carriage 12 and the installation chamber 13. The separation from the frame 32 is completed through the opening at the bottom of the installation chamber 13 and the preset interval between the base 21 and the placement cylinder 23. With the off-road capabilities of the vehicle's front end 11, a relatively flat and stable section of road is selected for parking and the frame 32 is set up as a fixed node for the water pipes. The water pipes are guided around terrain unsuitable for water flow to ensure smooth water delivery. Based on the distance between the water source and the fire site, multiple water pipes are passed through multiple frames 32 and connected to each other at the ends. The water pipes are firmly bound to the frame 32 by ropes, buckles and other means to form a water intake channel.
