[0002] Tank trucks can be divided into oil tankers, gas tankers, liquid tankers, powder tankers, cement mixer tankers, refueling tankers, etc. according to their uses. Tank trucks are transport vehicles with a tank-shaped body, used to transport various liquids, liquefied gases, powdered goods and other materials, or to transport gasoline, crude oil, various viscous oils, vegetable oils, liquid ammonia, alcohol, water, various acid and alkali liquids, cement lead oxide powder and other goods.

[0004] Leakage plugging training is a very important training item in firefighting training. To improve the firefighters' ability to respond to emergency scenes, various simulation trainings are usually conducted. Tank truck leak plugging training is a very important training item. Leak plugging here refers to the measures taken to seal leaks in tank trucks, pipelines, and other accidents during firefighting and emergency rescue. Firefighters often encounter various emergencies, such as tank truck oil tank leaks. When encountering such situations, how to deal with them safely and quickly requires repeated practice during regular training.

[0005] At present, in the existing technology of the equipment used for training firefighters to plug leaks in tank trucks, the leakage points are generally fixed and cannot be flexibly changed, so firefighters can only conduct repetitive and single training.

DETAILED DESCRIPTION

[0035] The following further describes specific embodiments of the present invention with reference to the accompanying drawings. Like components are denoted by like reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, and the terms "inward" and "outward" refer to directions toward or away from the geometric center of a particular component, respectively.

[0036] In the present invention, unless otherwise specified or limited, the term "fixed" and the like should be understood in a broad sense. For example, "fixed" can mean a fixed connection, a detachable connection, or an integral connection; a mechanical connection or an electrical connection; a direct connection or an indirect connection through an intermediate medium; and can mean internal communication between two elements or an interaction between two elements, unless otherwise specified. Those skilled in the art will be able to understand the specific meanings of the above terms in the present invention based on specific circumstances.

[0037] Currently, existing tank truck leak-plugging training devices generally use a cylinder to simulate the tank truck body, water to simulate oil, and various sensor structures for monitoring. However, the number, location, and angle of leak points on the leak-plugging training device are fixed, making it impossible to flexibly set the leak points. Consequently, the height or angle of the leak points cannot be adjusted to train firefighters to plug leaks at different locations or numbers of leaks. Furthermore, as a device for tank truck leak-plugging training, water leaks from the leak points can erode the surface of the training device over long-term training, leading to rust and even the appearance of other leaks, causing the training device to leak and impacting leak-plugging training.

[0038] like Figure 1-10 As shown, a tank truck leak plugging training device provided by one embodiment of the present invention includes a bracket 27 , a liquid storage barrel 1 rotatably connected to the bracket 27 , and a collection box 5 arranged below the liquid storage barrel 1 .

[0039] A liquid storage chamber 2 is formed inside the liquid storage barrel 1, and the two sides of the liquid storage chamber 2 are respectively connected to the liquid inlet pipe 11 and the liquid outlet pipe 26. A plurality of leakage pipes 3 and sealing components matching the leakage pipes 3 are provided in the liquid storage chamber 2. The end of each leakage pipe 3 forms a leakage point on the outer surface of the liquid storage barrel 1. The leakage point is switched between an open state and a closed state by controlling the sealing component.

[0040] like Figure 1-3As shown, brackets 27 are positioned on either side of a liquid storage barrel 1. The barrel 1 is cylindrical in structure, with its two end faces facing the brackets 27, and the centers of the two end faces are pivotally connected to the brackets 27, enabling the barrel 1 to rotate relative to the brackets 27. A liquid chamber 2 within the barrel 1 is used to hold a simulated liquid, such as water. The simulated liquid enters the chamber 2 through an inlet pipe 11 of the barrel 1. Excess simulated liquid in the chamber 2 flows out through an outlet pipe 26. To improve fluidity, the inlet pipe 11 can be positioned higher than the outlet pipe 26. Multiple leakage pipes 3 are positioned within the chamber 2, evenly spaced across the outer surface of the barrel 1 to create multiple leakage points. The opening and closing of each leakage point is controlled by a separate sealing assembly. A collection tank 5 is positioned beneath the barrel 1 to collect the simulated liquid flowing from the leakage points, effectively recycling the simulated solution and preventing resource waste.

[0041] In summary, the tank truck leak-plugging training device provided in an embodiment of the present invention comprises a liquid storage barrel 1 that is relatively rotatable on a bracket 27, and leak points that can be controlled to open or close on the outer side of the liquid storage barrel 1. By rotating the liquid storage barrel 1 and controlling the leak-plugging assembly, the number, height, and angle of the leak points can be adjusted in a variety of ways as needed to provide a variety of leak point combinations. This allows a single training device to simulate a variety of tank truck leaks, thereby improving the effectiveness of firefighter leak-plugging training and effectively reducing the overall training cost of firefighter leak-plugging training. Furthermore, a collection box 5 is provided below the liquid storage barrel 1 to collect simulated liquid leaking from the leak points on the liquid storage barrel 1, thereby enabling the recycling of the simulated liquid and avoiding resource waste.

[0042] In one embodiment, Figure 2 As shown, the bracket 27 includes a rotating rod 8, and the liquid storage barrel 1 includes an inner barrel body and an outer barrel body. The inner barrel body and the outer barrel body are coaxially arranged to form a hollow cylindrical liquid storage chamber 2. The inner barrel body is sleeved on the outer periphery of the rotating rod 8, and the fixed end of the sealing assembly is fixedly connected to the inner barrel.

[0043] In one embodiment, Figure 2 As shown, the liquid storage barrel 1 also includes a color development component for containing the color developer. One end of the color development component is connected to the inner barrel body, and the other end of the color development component is provided with a liquid guide hole 17 for discharging the color developer and extends into the liquid storage chamber 2.

[0044] In one embodiment, Figure 4 As shown, the color development component includes a tube cover 13 and a color development tube 16 whose end is connected to the tube cover 13.

[0045] The interior of the color developing tube 16 and the tube cover 13 forms a color developing agent accommodating chamber 19, and the color developing agent accommodating chamber 19 is provided with a containing groove 15 connected to the end of the tube cover 13. The end of the color developing tube 16 connected to the tube cover 13 is located on the inner side of the inner barrel body, and the other end of the color developing tube 16 is provided with a plurality of liquid guide holes 17 connected to the color developing agent accommodating chamber 19 and extending into the liquid containing chamber 2.

[0046] In one embodiment, Figure 2 and Figure 6 As shown, the blocking assembly includes an electric push rod 10 , the fixed end of the electric push rod 10 is fixedly connected to the inner barrel body, and the telescopic end of the electric push rod 10 is provided with a blocking column 12 for embedding and blocking the leakage pipe 3 .

[0047] In one embodiment, Figure 6 As shown, a push plate 24 is provided at the telescopic end of the electric push rod 10 , the area of ​​the push plate is larger than the area of ​​the leakage pipe 3 , and a first sealing gasket 25 is provided between the push plate and the leakage pipe 3 .

[0048] In one embodiment, Figure 2 and Figure 3 As shown, the interior of the collecting box 5 has a collecting chamber 7, the upper surface of the collecting box 5 is provided with a collecting groove 4 connected to the collecting chamber 7, and the top of both sides of the collecting groove 4 are provided with multiple absorption holes 20 connected to the collecting chamber 7. The collecting chamber 7 is connected to the suction pump through the absorption pipe 6, and the suction pump is connected to the discharge pipe 34.

[0049] In one embodiment, Figure 3 As shown, both sides of the collection box 5 are detachably connected to the bracket 27 via the mounting rods 30 , and the installation height of the collection box 5 can be adjusted by changing the connection position of the mounting rods 30 and the bracket 27 .

[0050] In one embodiment, Figure 5 and Figure 8 As shown, a cleaning cotton 23 is provided on the collecting groove 4, the upper end of the cleaning cotton 23 abuts against the lower end of the liquid storage barrel 1, a first plug hole 22 is opened in the middle of the cleaning cotton 23, and second plug holes 41 are opened at both ends of the collecting box 5, and the plug rod 21 slides through the second plug hole 41 and the first plug hole 22.

[0051] In one embodiment, Figure 7 and Figure 10 As shown, rotating handles 28 are provided at both ends of the rotating rod 8, and an angle dial 40 is provided on the outer side surface of the connection between the bracket 27 and the rotating handle 28.

[0052] As a specific implementation structure of the above embodiments, Figure 1-10As shown, the present invention provides a tank truck leak plugging training device, comprising a bracket 27, a liquid storage barrel 1 rotatably connected to the bracket 27, and a collection box 5 disposed below the liquid storage barrel 1. A rotating rod 8 passes through the middle of the liquid storage barrel 1, and a reinforcement frame 9 is fixed between the surface of the rotating rod 8 and the inner wall of the liquid storage barrel 1. The liquid storage barrel 1 is a cylindrical structure with openings at both ends. A liquid inlet pipe 11 is connected above one end of the liquid storage chamber 2, and a liquid outlet pipe 26 is connected below one end of the liquid storage chamber 2. The rotating rod 8 is arranged horizontally and fixedly connected to the liquid storage barrel 1 via the reinforcement frame 9 uniformly fixed to its surface. Brackets 27 are provided on the outer sides of each end of the liquid storage barrel 1. Rotating holes 35 are formed in the upper end surface of the bracket 27. The ends of the rotating rod 8 rotate through the rotating holes 35. Rotating handles 28 are fixed to each end of the rotating rod 8. Rotating the rotating rod 8 can drive the liquid storage barrel 1 to rotate in either the forward or reverse direction, and adjust the height and angle of the leakage pipe 3. A limit plate 39 is fixed to the surface of the rotating rod 8, located outside the rotation hole 35. The bracket 27 is rectangular and vertically arranged. The rotating handle 28 is L-shaped. The limit plate 39 is a circular plate structure and slides vertically against the outside of the bracket 27. A connection hole 37 is formed on the surface of the limit plate 39. A rotation groove 36 is formed on the outside of the bracket 27, located around the outside of the rotation hole 35. A tightening bolt 38 passes through the connection hole 37. The inner end of the tightening bolt 38 is inserted into the rotation groove 36. After the rotating rod 8 rotates the liquid bucket 1 to the training angle, the inner end of the tightening bolt 38 presses against the bracket 27, keeping the rotating rod 8 and the liquid bucket 1 stable between the two brackets 27 and preventing any shaking. The rotation groove 36 is an annular groove structure with a depth less than the thickness of the bracket 27. The connecting hole 37 is a threaded hole structure and is aligned with the rotation groove 36. The tightening bolt 38 is horizontally arranged and threadedly engaged with the connecting hole 37, with its inner end pressing against the bracket 27. An angle scale 40 is provided on the outside of the bracket 27 and around the outside of the limit plate 39. The angle scale 40 is a circular structure with angle values ​​engraved on its surface. The angle of rotation of the liquid storage barrel 1 and the leakage pipe 3 can be known through the angle scale 40.

[0053] like Figure 2 and Figure 3As shown, a liquid storage chamber 2 is provided in the barrel wall of the liquid storage barrel 1. An electric push rod 10 is installed inside the liquid storage barrel 1. The inner end of the electric push rod 10 is inserted into the liquid storage chamber 2. A push plate 24 is fixed to the inner end of the electric push rod 10. The blocking column 12 is made of rubber, and its outer end is recessed inside the leakage pipe 3. The push plate 24 is cushioned by a first sealing gasket 25 and pressed against the inner end surface of the leakage pipe 3. The leakage pipe 3 is fixed to the outside of the liquid storage barrel 1. The electric push rod 10 is perpendicular to the interior of the liquid storage barrel 1, and its inner end is tightly inserted into the interior of the liquid storage chamber 2 and aligned with the leakage pipe 3. The leakage pipe 3 is a circular tubular structure, and its outer end is flush with the outer surface of the liquid storage barrel 1. The leakage pipe 3 serves as a simulated leakage point on the surface of the leak plugging training device. Multiple leakage pipes 3 are set at different heights and angles on the outer surface of the liquid barrel 1. The side of the push plate 24 is fixed with a sealing column 12 that is tightly inserted into the leakage pipe 3. The side of the push plate 24 is bonded with a first sealing gasket 25 that is tightly pads the end of the leakage pipe 3. The electric push rod 10 drives the pushing plate 24, the sealing column 12 and the first sealing gasket 25 to open or close the inner end of the leakage pipe 3, and the electric push rod 10 drives the pushing plate 24 and the sealing column 12 to open one or more leakage pipes 3, forming one or more leakage points at different heights and angles, so as to train firefighters to deal with one or more leakage points at different heights and angles on the tank truck for leak plugging operations.

[0054] External clean water enters the liquid storage chamber 2 from the liquid inlet pipe 11, and the leakage pipe 3, the color development pipe 16 and the liquid outlet pipe 26 are all in a closed state. Thereafter, by turning the handle 28 to rotate the rotating rod 8 forward or reverse, the liquid storage barrel 1 is driven to rotate, and the leakage pipe 3 is rotated to adjust to different heights and angles. The tightening bolt 38 fastens the limit plate 39 to the outside of the bracket 27, keeping the rotating rod 8 and the liquid storage barrel 1 stable. The angle of rotation of the liquid storage barrel 1 and the leakage pipe 3 can be known by the angle dial 40. When firefighters are conducting leak plugging training, the electric push rod 10 can drive the push plate 24 and the blocking column 12 to open one or more leakage pipes 3, forming one or more leak points at different heights and angles on the surface of the liquid storage barrel 1 for firefighters to conduct leak plugging training. In this way, firefighters are trained to perform leak plugging operations on one or more leak points at different heights and angles on the tank truck, thereby increasing the intensity and complexity of tank truck leak plugging training and improving firefighters' skills in tank truck leak plugging.

[0055] A color development component is disposed within the liquid chamber 2. Specifically, a color development tube 16 is inserted into the liquid chamber 2. The color development tube 16 is offset from the electric push rod 10. A color developer chamber 19 is disposed within the color development tube 16. The color development tube 16 is a circular tubular structure, with its outer end protruding from the inner wall of the liquid barrel 1 and its inner end being a sealed structure. The color developer chamber 19 is a threaded groove structure, and the color developer chamber 19 is connected to the liquid chamber 2 via a liquid guide hole 17. A liquid guide hole 17 is formed on the surface of the color development tube 16, located within the liquid chamber 2. A plug-in post 18 is threadedly inserted into the outer end of the color developer chamber 19. The plug-in post 18 is a threaded post structure and is threadedly connected to the color developer chamber 19, with a spacing between its inner end and the liquid guide hole 17. A central portion of the plug-in post 18 defines a holding groove 15. This cylindrical structure connects its inner end to the developer chamber 19 and is shorter than the length of the plug-in post 18. A tube cap 13, padded with a second gasket 14, presses against the outer end surface of the color development tube 16. The holding groove 15 holds the developer, which can be a natural, environmentally friendly dye of various colors, such as curcumin extracted from ginger juice, cochineal carmine, or sappanin extracted from sappan wood. This dye is used to color water, simulating various liquids transported in tank trucks. This makes water leaking from the leak pipe 3 on the surface of the liquid storage tank 1 more visible and easier to observe, improving the environmental performance of the leak and preventing the leak from harming human skin and contaminating nearby ground and water sources during leak-proofing training. A tube cap 13 is secured to the outer end of the plug-in post 18. A second gasket 14 is bonded to the side of the cap 13, which pads the end of the color development tube 16.

[0056] As the rotating rod 8 drives the liquid storage barrel 1 to rotate to adjust the height and angle of the leakage pipe 3, the clean water inside the liquid storage chamber 2 can flush the color development pipe 16 and mix with the color developer through the liquid guide hole 17, the color developer accommodating chamber 19 and the holding tank 15. The clean water and the color developer in the liquid storage chamber 2 are stirred by the inner ends of the multiple electric push rods 10 and the color development pipe 16, so that the color developer is fully mixed with the clean water and the clean water is colored, so as to simulate various liquids transported in the tank truck, and the leakage pipe 3 on the surface of the liquid storage barrel 1 can be made to leak. The water coming out is more conspicuous and easy to observe, which is helpful for trained firefighters to quickly find the leakage point of the tank truck. It can also detect the airtightness of the liquid chamber 2. Since the liquid chamber 2 is used to hold clean water for a long time for training, it is easy for the surface of the liquid chamber 2 to rust and leak holes other than the leakage pipe 3 to appear. Therefore, after filling the liquid chamber 2 with clean water and mixing with the color developer, the leakage pipe 3 is closed, and the inner and outer surfaces of the liquid barrel 1 are observed to determine the airtightness of the liquid chamber 2, so as to avoid the appearance of leak holes other than the leakage pipe 3 due to rust on the surface of the liquid chamber 2 and affect the leak plugging training.

[0057] A collection box 5 is mounted at the lower end of the liquid storage barrel 1. This box 5 is longer than the length of the liquid storage barrel 1 and narrower than its diameter. A collection chamber 7 is provided within the collection box 5. A suction pipe 6 is connected to the lower end of the collection box 5. A suction pump 33 is mounted at the lower end of the suction pipe 6. A discharge pipe 34 is connected to the side of the suction pump 33. The pump draws air and clean water from the collection chamber 7 through the suction pipe 6 and discharges them through the discharge pipe 34. A liquid recovery frame (not shown) can be installed at the outer end of the discharge pipe 34 to recover the collected water. The water collected by the collection box 5 can be recycled repeatedly. Mounting rods 30 are fixed to both ends of the collection box 5. Mounting slots 29 are defined on the surface of the bracket 27 below the rotation hole 35. The mounting rods 30 slide through the mounting slots 29. Nuts 31 are attached to the surface of the mounting rods 30 on either side of the mounting slots 29. The collection box 5 can be removably and vertically adjusted by the mounting rods 30 and nuts 31. The mounting rods 30 are threaded rods and are arranged horizontally. The mounting slots 29 are elongated and open at their lower ends. The mounting rods 30 are mounted and connected to the bracket 27 via nuts 31. Stabilizing brackets 32 are fixed obliquely to both sides of the bracket 27.

[0058] The upper end of the collection box 5 is provided with a collection groove 4, which is provided with an absorption hole 20. The airflow generated by the suction of the absorption hole 20 blows over the surface of the liquid bucket 1, quickly drying the moisture on the surface of the liquid bucket 1 and quickly drying the cleaning cotton 23. The collection groove 4 is an arc-shaped groove structure, and the absorption holes 20 are evenly distributed on the lower end surface of the collection groove 4. The collection groove 4 is connected to the collection chamber 7 through the absorption holes 20. The collection box 5 is connected to the collection chamber 7 through the absorption holes 20. The cleaning cotton 23 is installed at the upper end of the collection box 5 and located in the middle of the collection groove 4. The cleaning cotton 23 is an elongated structure and is longer than the length of the liquid bucket 1. The upper end of the cleaning cotton 23 abuts the lower end of the liquid bucket 1. The cleaning cotton 23 brushes and cleans the surface of the liquid bucket 1, removing dust attached to the surface of the liquid bucket 1 and brushing the water mixed with the developer adhering to the surface of the liquid bucket 1.

[0059] During the firefighters' training, the leakage pipe 3 is opened to simulate the leakage point, and the leakage point plugging training is carried out. The clean water after mixing with the developer will soak the surface of the liquid bucket 1, causing the surface of the liquid bucket 1 to be wet. After the firefighters' leak plugging training is completed, the leakage pipe 3 is closed, and the rotating rod 8 and the liquid bucket 1 are continuously rotated, so that the cleaning cotton 23 brushes and cleans the surface of the liquid bucket 1, which can clean the dust attached to the surface of the liquid bucket 1 and brush the water mixed with the developer attached to the surface of the liquid bucket 1. At the same time, the water pump absorbs air and clean water from the inside of the collection chamber 7 through the absorption pipe 6, and discharges the air and clean water from the discharge chamber 7. The liquid is discharged through the outlet pipe 34, and a liquid recovery frame (not shown in the figure) can be set to receive the collected water in the collection box 5, which can be reused repeatedly. Moreover, the suction force of the suction pump 33 can form an air flow on the surface of the absorption hole 20 inside the collection groove 4. During the rotation of the rotating rod 8 and the liquid bucket 1, the air flow formed by the suction of the absorption hole 20 will blow on the surface of the liquid bucket 1, so that the moisture on the surface of the liquid bucket 1 is quickly dried, and the cleaning cotton 23 is quickly dried, which is beneficial to the long-term safe use of the liquid bucket 1 without rust, and facilitates the cleaning cotton 23 to repeatedly brush and clean the surface of the liquid bucket 1.

[0060] A first insertion hole 22 is formed in the middle of the cleaning cotton 23, and second insertion holes 41 are formed at both ends of the collection box 5. A plug rod 21 slides through the interior of the second insertion hole 41 and the first insertion hole 22. The plug rod 21 and the collection box 5 can support the lower end of the liquid storage bucket 1, preventing the middle of the rotating rod 8 from bending due to the excessive weight of the liquid storage bucket 1. Moreover, the plug rod 21 is removable and easy to remove, install, and replace the cleaning cotton 23. The second insertion hole 41 is located in the middle of the two ends of the collection groove 4, and the first insertion hole 22 and the second insertion hole 41 are aligned. The two ends of the plug rod 21 protrude from the second insertion hole 41 and are evenly distributed at the lower end of the liquid storage bucket 1.

[0061] To sum up, in the first aspect, the present invention provides a liquid storage chamber 2 in the inner wall of the liquid storage barrel 1, the rotating rod 8 passes through the inner middle part of the liquid storage barrel 1, and is fixedly connected to the interior of the liquid storage barrel 1 through the reinforcement frame 9, and the two ends of the rotating rod 8 are rotatably mounted and connected to the bracket 27 through the rotating hole 35, the limit plate 39 and the tightening bolt 38, and an angle dial 40 is provided on the outer side of the limit plate 39.

[0062] Furthermore, multiple leakage tubes 3 are positioned at different heights and angles on the outer surface of the liquid storage barrel 1. Within the liquid storage chamber 2, an electric push rod 10 drives a push plate 24, a blocking column 12, and a first sealing gasket 25 to switch the inner end of the leakage tube 3 between an open and closed state. When clean water enters the liquid storage chamber 2 from the external liquid inlet pipe 11, the leakage tube 3, the color development tube 16, and the liquid outlet pipe 26 are all in a closed state. Subsequently, by turning the handle 28, the rotating rod 8 rotates, driving the liquid storage barrel 1 to rotate, thereby rotating and adjusting the leakage tube 3 to different heights and angles. The tightening bolt 38 secures the limit plate 39 to the outside of the bracket 27, maintaining the stable position of the rotating rod 8 and the liquid storage barrel 1. The angle of rotation of the liquid storage barrel 1 and the leakage tube 3 can be determined using the angle dial 40.

[0063] When firefighters are conducting leak plugging training, the electric push rod 10 can drive the push plate 24 and the blocking column 12 to open one or more leakage pipes 3, forming one or more leakage points at different heights and angles, so as to train firefighters to perform leak plugging operations in response to one or more leakage points at different heights and angles on the tank truck, thereby increasing the intensity and complexity of tank truck leak plugging training and improving firefighters' skills in dealing with tank truck leak plugging.

[0064] Secondly, the present invention incorporates a color development assembly within the liquid chamber 2. A plug-in post 18 is inserted into the color development tube 16 within the color development assembly. A color developer is placed in a receiving groove 15 within the plug-in post 18, and the outer end of the color development tube 16 is tightly capped with a tube cap 13. As the rotating rod 8 rotates the liquid storage barrel 1 to adjust the height and angle of the leakage tube 3, clean water within the liquid storage barrel 2 flushes the color development tube 16 and mixes with the developer through the liquid guide hole 17, the developer receiving chamber 19, and the receiving groove 15. The inner ends of multiple electric push rods 10 and the color development tube 16 agitate the clean water and developer in the liquid storage chamber 2, ensuring that the developer fully mixes with the clean water and develops color, thereby simulating various liquids transported in tank trucks. This also makes water leaking from the leakage tube 3 on the surface of the liquid storage barrel 1 more visible and easier to observe, helping trained firefighters quickly identify leaks in tank trucks and verifying the tightness of the liquid storage chamber 2.

[0065] Since the liquid chamber 2 holds clean water for a long time during training, it is easy for the surface of the liquid chamber 2 to rust and leak holes other than the leakage tube 3 to appear. You can fill the liquid chamber 2 with clean water and mix it with a color developer, then seal the leakage tube 3 and observe the inner and outer surfaces of the liquid barrel 1 to determine the airtightness of the liquid chamber 2 to avoid leak holes other than the leakage tube 3 due to rust on the surface of the liquid chamber 2.

[0066] Thirdly, the present invention detachably mounts a collection box 5 between two brackets 27 via a mounting rod 30 and a nut 31, allowing for vertical adjustment. Furthermore, the collection box 5 is positioned at the lower end of the liquid bucket 1. Cleaning cotton 23 is detachably mounted within the collection groove 4 at the top of the collection box 5 via a plug-in rod 21, with the top end of the cleaning cotton 23 abutting the lower end of the liquid bucket 1. The plug-in rod 21 and the collection box 5 support the lower end of the liquid bucket 1, preventing the middle portion of the rotating rod 8 from bending due to the excessive weight of the liquid bucket 1.

[0067] During the firefighter training, the leakage pipe 3 is opened to simulate the leakage point, and the leakage point plugging training is carried out. The clean water after mixing with the color developer will soak the surface of the liquid bucket 1, causing the surface of the liquid bucket 1 to be wet. After the firefighters complete the leak plugging training, the leakage pipe 3 is closed, and the rotating rod 8 and the liquid bucket 1 are continuously rotated, so that the cleaning cotton 23 brushes and cleans the surface of the liquid bucket 1, which can clean the dust attached to the surface of the liquid bucket 1 and brush the water mixed with the color developer attached to the surface of the liquid bucket 1.

[0068] At the same time, the water pump absorbs air and clean water from the collection chamber 7 through the absorption pipe 6 and discharges them from the discharge pipe 34. A liquid recovery frame can be provided to recover the collected water in the collection box 5 for repeated use. Moreover, the suction force of the suction pump 33 can generate airflow on the surface of the absorption hole 20 inside the collection groove 4. During the rotation of the rotating rod 8 and the liquid storage barrel 1, the airflow generated by the suction of the absorption hole 20 will blow over the surface of the liquid storage barrel 1, so that the moisture on the surface of the liquid storage barrel 1 is quickly dried, and the cleaning cotton 23 is quickly dried, which is conducive to the long-term and safe use of the liquid storage barrel 1 without rust, so that the cleaning cotton 23 can repeatedly brush and clean the surface of the liquid storage barrel 1.

[0069] As needed, the above technical solutions can be combined to achieve the best technical effect.

[0070] The above are only the principles and preferred embodiments of the present invention. It should be noted that, for those skilled in the art, several other variations can be made based on the principles of the present invention, which should also be considered as the scope of protection of the present invention.
