Description

Technical Field

[0001] The present invention relates to the technical field of explosion extinguishing devices, and in particular to a rapid explosion extinguishing device for hazardous chemical leakage based on a chemical neutralization reaction. Background Art

[0002] The rapid explosion extinguishing device for hazardous chemical leakage based on chemical neutralization reaction is a device designed for the risk of explosion caused by hazardous chemical leakage. Its core principle is to use chemical neutralization reaction to neutralize the chemical properties of hazardous chemicals, reduce their hazard, and thus achieve the purpose of explosion extinguishing. During the transportation of hazardous chemicals by hazardous chemical transport vehicles, if the vehicle leaks hazardous chemicals due to accidents or other reasons, firefighters will quickly arrive at the scene and use fire hoses to spray liquid neutralizers corresponding to the properties of the leaked hazardous chemicals. Through the chemical neutralization reaction between the two, the activity and hazard of the hazardous chemicals are effectively reduced, thereby achieving explosion extinguishing, avoiding the occurrence of explosion accidents, and ensuring the safety of on-site personnel and the environment.

[0003] When using a fire hose to spray a liquid neutralizer corresponding to the properties of the leaked hazardous chemicals to achieve explosion extinguishing, the firefighter is affected by the pressure of the liquid neutralizer sprayed by the fire hose, and the reaction force he receives when holding the fire hose to spray the liquid neutralizer is relatively large. When the area of ​​the leaked hazardous chemicals is large, he needs to hold the fire hose for a long time to spray the liquid neutralizer, which will cause the muscles in the arms, shoulders, neck and other parts of the firefighter to quickly fatigue, thereby affecting the firefighter's ability to continue handling. Therefore, the present application provides a rapid explosion extinguishing device for hazardous chemical leaks based on chemical neutralization reaction to meet the needs. Summary of the Invention

[0004] The present invention provides a rapid explosion extinguishing device for hazardous chemical leaks based on a chemical neutralization reaction to solve the problem that firefighters are subjected to a large reaction force when holding a fire hose and spraying a liquid neutralizer. When the hazardous chemical leak area is large and a long time is required to spray, it is easy to cause rapid fatigue of the arm, shoulder and neck muscles, thereby affecting the firefighters' ability to continue working.

[0010] Preferably, a pedal is rotatably connected to the top of the base plate, and the pedal is inclined. The side of the pedal facing the direction of water spraying from the fire water gun is higher than the side of the pedal away from the direction of water spraying from the fire water gun. A baffle is fixed on the side of the base plate away from the direction of water spraying from the fire water gun, and the bottom of the baffle extends downward to the bottom of the base plate.

[0011] Preferably, a driving assembly and a rolling assembly are provided at the bottom of the base plate, the driving assembly includes a vertical rod that is vertically movable and passes through the base plate, a square sleeve is inlaid at the position of the vertical rod at the top of the base plate corresponding to the vertical rod, the vertical rod is slidably connected to the square sleeve, the top of the vertical rod is slidably connected to the bottom of the pedal, a connecting plate is fixed to the bottom of the vertical rod, a tension spring is connected between the connecting plate and the base plate, movable plates are fixed on the opposite sides of the connecting plate, and locking blocks are fixed on the departing surfaces of the two movable plates, and the rolling assembly includes two wheel axles rotatably connected to the bottom of the base plate through an axle seat, and roller two is fixedly sleeved at both ends of the wheel axle, and roller two is in contact with the ground. When the pedal is stepped on, the pedal drives the vertical rod to move downward so that the locking block is tightly fitted with the wheel axle, thereby realizing the locking of roller two.

[0012] Preferably, the top of the vertical rod is rotatably connected to a roller 1, and the outer wall of the roller 1 is in contact with the bottom of the pedal.

[0013] The outer wall of the wheel shaft is fixed with a plurality of connecting rods, and the outer wall of the connecting rod is fixed with a plurality of connecting rods. The outer wall of the wheel shaft is fixed with a plurality of connecting rods, and the outer wall of the wheel shaft is fixed with a plurality of connecting rods.

[0014] Preferably, an anti-skid column is fixed to the outer wall of the second roller, and the side of the anti-skid column away from the rotation axis of the second roller is a plane. When the arc surface on the slide bar contacts the ground, the anti-skid column also contacts the ground.

[0015] Preferably, both ends of the slide bar are provided with inclined surfaces, and a circular chamfer is provided at the connection between the inclined surface and the arc surface.

[0016] Preferably, the outer wall of the limiting sleeve is a regular polygon, and the shape of the guide sleeve is adapted to the shape of the limiting sleeve.

[0017] Compared with the prior art, the present invention has at least the following beneficial effects:

[0018] In the above scheme, a bracket and a base plate are provided, and the fire hose is installed on the top of the bracket. The base plate is in contact with the ground. The bracket is used to provide rigid support for the fire hose. At the same time, the spray angle is adjusted through the connecting assembly on the top of the bracket. When spraying liquid neutralizer, the firefighter holds the fire hose with one hand to control the spray direction, holds the fire hose with the other hand, and steps on the base plate and the ground with both feet to form a stable support. At this time, part of the reaction force generated by the spraying is transmitted to the ground through the cooperation of the bracket and the base plate, which effectively reduces the physical load of the firefighter, reduces the labor intensity of the firefighter, and ensures its continuous handling ability of dangerous situations. It is therefore suitable for large-scale leakage scenarios of hazardous chemicals.

[0019] By arranging pedals and baffles, the pedals are inclined, and the side of the pedals facing the direction of water spraying from the fire hose is higher than the side of the pedals away from the direction of water spraying from the fire hose, forming a support surface that matches the direction of reaction force transmission. When the reaction force generated by the fire hose spraying liquid neutralizer is transmitted to the bottom plate at the bottom of the bracket, the firefighter steps on the inclined pedal with his feet, and uses the downward pressure component formed by the stepping pressure and the inclination angle of the pedal to stabilize and limit the bottom plate, effectively preventing the bottom plate from tilting upward under the action of the spraying reaction force. At the same time, the baffle is used to limit the firefighter's feet to avoid separation of the feet from the bottom plate during stepping, thereby ensuring continuous and stable downward pressure on the bottom plate, further enhancing the anti-dumping ability of the entire support mechanism, and ensuring the smooth progress of the fire hose spraying operation.

[0020] By setting up roller two, which is installed at the bottom of the base plate, when explosion-fighting treatment is required for other hazardous chemical leakage areas, roller two is used to facilitate the movement of the entire support mechanism and the fire hose, thereby facilitating the movement of the fire hose to other leakage areas for explosion-fighting treatment.

[0021] By setting a locking block and a sliding bar, when the fire hose is moved to the target position and the pedal is stepped on, the pedal presses the vertical rod to make the movable plate drive the locking block to move downward, locking the wheel axle to prevent the roller two from rotating at will, thereby achieving stable support for the fire hose. At the same time, during the downward movement of the movable plate, the sliding sleeve is driven to move horizontally through the cooperation of the inclined groove and the columnar block, thereby making the movable plate push the sliding bar to extend from the trapezoidal notch of the roller two, increasing the width of the roller two, thereby increasing the supporting area of ​​the supporting mechanism at the roller two, and achieving stable support of the roller two on the road surface for the fire hose. When the roller two stops moving on the road surface, the two arc surfaces on its two adjacent sliding bars fit into the road surface, and the two arc surfaces The plane formed between the surfaces enhances the contact stability between the slider and the road surface, prevents the second roller from rotating on the road surface, and ensures the reliable use of the support mechanism in the highway scene. When hazardous chemicals leak from the highway to the land beside, the support mechanism is moved to the land for use. The extended slider will expose the trapezoidal notch of the second roller. At this time, after stepping on the pedal, affected by the structural characteristics of the large gap between the trapezoidal notch on the second roller and the adjacent slider, the outer wall of the second roller corresponding to the solid part between the two adjacent trapezoidal notches is inserted into the ground soil synchronously with the slider, and the soil's interlocking resistance is used to further enhance the anti-slip ability of the support mechanism. Through the above design, the stable use of the support mechanism on the road surface and the land is guaranteed.

[0022] When the slider moves in the opposite direction, the soil attached to the side of the slider is scraped off by the inner wall of the trapezoidal notch, thereby realizing automatic cleaning of the slider and the trapezoidal notch, effectively preventing soil residue from affecting the subsequent movement of the slider and preventing the soil in the trapezoidal notch from affecting the subsequent insertion of the outer wall of the second roller into the soil.

[0023] By setting anti-skid columns, when the two arc surfaces on the two adjacent sliding strips fit with the road surface on the road surface, the anti-skid columns will fit with the road surface synchronously, and the contact area between the second roller and the road surface will be increased by the anti-skid columns, thereby increasing the friction between the second roller and the road surface, effectively preventing the rolling assembly from sliding on the road surface, and further improving the stable support ability of the rolling assembly to the support mechanism. When pushing the support mechanism to move on the ground, the friction between the second roller and the soil will be increased by the anti-skid columns, ensuring the stable rotation of the second roller on the ground and preventing the second roller from slipping when used on the ground, thereby ensuring the smooth movement of the support mechanism.

[0024] By setting an inclined surface, the inclined surface is opened at the end of the slider, and a circular chamfer is opened at the connection between the inclined surface and the arc surface. When the slider moves horizontally on the road surface and the ground, the design of the inclined surface and the circular chamfer prevents the sharp edges at the end of the slider from hindering the horizontal movement of the slider on the ground and the road surface, thereby preventing the slider from getting stuck during the movement and ensuring the stable horizontal movement of the slider on the ground and the road surface.

DETAILED DESCRIPTION

[0036] The following describes in detail a device for rapidly extinguishing hazardous chemical leaks based on a chemical neutralization reaction, provided by the present invention, in conjunction with the accompanying drawings and specific embodiments. It is also noted that, to provide a more detailed description, the following embodiments are best and preferred embodiments, and those skilled in the art may employ alternative implementations for known techniques. Furthermore, the accompanying drawings are provided solely for the purpose of describing the embodiments in greater detail and are not intended to limit the present invention.

[0037] like Figures 1-9 As shown, an embodiment of the present invention provides a rapid explosion extinguishing device for hazardous chemical leakage based on a chemical neutralization reaction, comprising a fire hose 1, and further comprising:

[0038] The support mechanism 2 includes a support assembly 8, which includes a bracket 9. A connecting assembly 3 is installed on the top of the bracket 9. The connecting assembly 3 is used for the rotational connection between the fire hose 1 and the bracket 9 and for adjusting the spray angle of the fire hose 1. A base plate 10 is provided at the bottom of the bracket 9. The base plate 10 is used to support the fire hose 1. By providing the bracket 9 and the base plate 10, the fire hose 1 is installed on the top of the bracket 9, and the base plate 10 is in contact with the ground. The bracket 9 is used to rigidly support the fire hose 1, and at the same time, the spray angle is adjusted by the connecting assembly 3 on the top of the bracket 9. When spraying liquid neutralizer, the firefighter holds the fire hose 1 with one hand to control the spray direction, holds the fire hose with the other hand, and steps on the base plate 10 and the ground with both feet to form a stable support. At this time, part of the reaction force generated by the spraying is transmitted to the ground through the cooperation of the bracket 9 and the base plate 10, effectively reducing the limb load of the firefighter, reducing labor intensity, and ensuring the continuous handling capability of dangerous situations. It is suitable for large-scale leakage scenarios of hazardous chemicals.

[0039] like Figure 2 As shown, in this embodiment, the connecting assembly 3 includes an upper connecting seat 4 and a lower connecting seat 5. A clamp is installed on the outer wall of the fire water gun 1. The upper connecting seat 4 is fixed to the bottom of the clamp. The upper connecting seat 4 and the lower connecting seat 5 are rotatably connected by a circular shaft. The circular shaft is used to adjust the pitch angle of the fire water gun 1. A rotating shaft 7 is fixed to the bottom of the lower connecting seat 5. A square seat 6 is fixed to the top of the bracket 9. The rotating shaft 7 is rotatably connected in the square seat 6. The rotating shaft 7 is used to adjust the horizontal angle of the fire water gun 1. The upper connecting seat 4 is fixed to the fire water gun 1 through a clamp. The upper connecting seat 4 and the lower connecting seat 5 are connected by a The circular axis rotation connection can realize the pitch angle adjustment of the fire hose 1. The rotating shaft 7 of the lower connecting seat 5 rotates in the square seat 6 to adjust the horizontal angle of the fire hose 1. The combination of the two enables firefighters to accurately adjust the spray direction according to the location of the hazardous chemical leakage, thereby improving the pertinence and efficiency of the explosion-fighting operation. At the same time, when the hazardous chemical leakage area is not suitable for the use of the support mechanism 2, the fire hose 1 can be directly pulled upward to separate the rotating shaft 7 from the square seat 6, and the connection between the fire hose 1 and the support mechanism 2 can be released. After the release, the fire hose 1 can be used normally to spray liquid neutralizer for explosion-fighting treatment.

[0040] like Figure 1 and Figure 2As shown, in this embodiment, side panels 11 are fixed to the opposite sides of the bracket 9, and a square plate 12 is fixed to the top of the bottom plate 10. The square plate 12 is slidably connected to the side of the side panel 11, and the side of the square panel 12 is threadedly connected to a locking member. The locking member is used to fix the square panel 12 after it slides on the side of the side panel 11. The side panels 11 on the side of the bracket 9 are slidably connected to the square panel 12. After unscrewing the locking member from the hole on the side of the side panel 11, the bracket 9 can be moved upward or downward to adjust its height, thereby realizing the adjustment of the height of the fire hose 1. After adjusting to the appropriate height, the locking member can be screwed into the corresponding hole to fix the bracket 9, thereby adapting to the use needs of firefighters of different heights.

[0041] like Figure 1 and Figure 3 As shown, in this embodiment, the top of the base plate 10 is rotatably connected to a pedal 13, and the pedal 13 is inclined. The side of the pedal 13 facing the water spraying direction of the fire hose 1 is higher than the side of the pedal 13 away from the water spraying direction of the fire hose 1. A baffle 14 is fixed on the side of the base plate 10 away from the water spraying direction of the fire hose 1, and the bottom of the baffle 14 extends downward to the bottom of the base plate 10. The side of the pedal 13 facing the water spraying direction is higher, forming a support surface matching the direction of reaction force conduction. When the fire hose 1 sprays liquid neutralizer to generate a reaction force, the firefighter steps on the inclined pedal 13, and uses the downward pressure component formed by the stepping pressure and the inclination angle of the pedal 13, and the baffle 14 limits the foot to prevent the foot from detaching, thereby ensuring stable downward pressure on the base plate 10, effectively preventing the base plate 10 from tilting upward under the reaction force, enhancing the anti-dumping ability of the support mechanism 2, and ensuring stable use of the fire hose 1.

[0042] like Figure 3-Figure 6As shown, in this embodiment, a driving assembly 15 and a rolling assembly 30 are provided at the bottom of the base plate 10. The driving assembly 15 includes a vertical rod 16 that vertically moves through the base plate 10. A square sleeve is inlaid at the position of the vertical rod 16 at the top of the base plate 10. The vertical rod 16 is slidably connected in the square sleeve. The top of the vertical rod 16 is slidably connected to the bottom of the pedal 13. A connecting plate 18 is fixed to the bottom of the vertical rod 16. A tension spring 19 is connected between the connecting plate 18 and the base plate 10. Movable plates 20 are fixed on opposite sides of the connecting plate 18. Locking blocks 23 are fixed to the departing surfaces of the two movable plates 20. The rolling assembly 30 includes two wheel axles 32 rotatably connected to the bottom of the base plate 10 through an axle seat. Both ends of the wheel axle 32 are fixedly sleeved with rollers 2 31, roller 2 31 is in contact with the ground. When pedal 13 is stepped on, pedal 13 drives vertical rod 16 to move downward so that locking block 23 is closely fitted with axle 32, thereby locking roller 2 31. When pedal 13 is stepped on, pedal 13 drives vertical rod 16 to move downward through roller 1 17, and vertical rod 16 drives connecting plate 18 to move downward. Tension spring 19 is stretched, and connecting plate 18 drives movable plate 20 to move downward so that locking block 23 is closely fitted with axle 32, thereby locking roller 2 31, preventing support mechanism 2 from moving, ensuring the stability of fire hose 1 during spraying, and at the same time, the spraying reaction force is transmitted to bottom plate 10 through bracket 9, and then transmitted to the ground through roller 2 31, thereby reducing the limb load of firefighters.

[0043] like Figure 5 As shown, in this embodiment, the top of the vertical rod 16 is rotatably connected to a roller 17, and the larger outer wall of the roller 17 fits against the bottom of the pedal 13. The roller 17 at the top of the vertical rod 16 fits against the bottom of the pedal 13. When the pedal 13 rotates downward, the roller 17 can reduce the friction between the pedal 13 and the vertical rod 16, making the up and down movement of the vertical rod 16 smoother, thereby ensuring the reliability and service life of the drive component 15.

[0044] like Figure 4-Figure 7As shown, in this embodiment, a sliding sleeve 24 is slidably sleeved on the wheel axle 32, a columnar block 21 is fixed to the outer wall of the sliding sleeve 24, an inclined groove 22 is provided on the side of the movable plate 20 corresponding to the position of the columnar block 21, and the columnar block 21 is slidably connected in the inclined groove 22, and a connecting strip 25 is fixed to the end of the sliding sleeve 24, and a circular cover 26 is fixed to the end of the connecting strip 25 away from the sliding sleeve 24, and a guide sleeve 27 is rotatably connected in the circular cover 26. A limiting sleeve 28 is fixedly sleeved on the wheel axle 32, and the inner wall of the guide sleeve 27 is slidably connected to the outer wall of the limiting sleeve 28. A movable disk 29 is fixed to the end of the guide sleeve 27 away from the circular cover 26, and the movable disk 29 is slidably sleeved on the limiting sleeve The outer wall of the position sleeve 28 and the side of the movable disk 29 away from the circular cover 26 are fixed with several connecting columns 38. The end of the connecting column 38 away from the movable disk 29 is fixed with a slide bar 34. The outer wall of the roller 2 31 is provided with several trapezoidal notches 33. The slide bar 34 is slidably connected in the trapezoidal notch 33. The side of the slide bar 34 away from the rotation axis of the roller 2 31 protrudes from the outer wall of the roller 2 31 and forms an arc surface 36. After the wheel axle 32 is locked by the locking block 23, the slide bar 34 extends from the trapezoidal notch 33, and the arc surfaces 36 on the two adjacent slide bars 34 are in contact with the ground. The circular cover 26 is fixedly connected to the outer wall of the bearing, and the outer wall of the guide sleeve 27 is connected to the shaft. The inner wall of the bearing is fixedly connected, and the rotation connection between the round cover 26 and the guide sleeve 27 is realized by the bearing. When the round cover 26 moves, the guide sleeve 27 is driven to move by the bearing. When the movable plate 20 moves down with the connecting plate 18, the inclined inner wall of the inclined groove 22 on one side squeezes the columnar block 21, so that the sliding sleeve 24 moves on the wheel shaft 32 toward the direction of the second roller 31. The sliding sleeve 24 drives the round cover 26 to move through the connecting strip 25. The round cover 26 drives the guide sleeve 27 to slide on the limit sleeve 28 toward the direction of the second roller 31 through the bearing. The guide sleeve 27 pushes the movable plate 29 to move, and the movable plate 29 drives the slide bar 34 from the second roller 31 through the connecting column 38. The trapezoidal notch 33 extends outward to increase the width and support area of ​​the second roller 31. When used on the road, the arc surface 36 of the two adjacent slide bars 34 contacts the ground. The plane formed between the two arc surfaces 36 enhances the contact stability between the rolling assembly 30 and the road surface, preventing the second roller 31 from rotating and achieving stable support. When used on land, the slide bar 34 extends out to expose the trapezoidal notch 33. After stepping on the pedal 13, the outer wall of the second roller 31 corresponding to the solid part between the adjacent trapezoidal notches 33 is inserted into the soil synchronously with the slide bar 34, and the soil interlocking resistance is used to enhance the anti-slip ability of the support mechanism 2, thereby ensuring the stable use of the support mechanism 2 on different terrains.

[0045] like Figure 7-Figure 9As shown, in this embodiment, an anti-skid column 37 is fixed to the outer wall of the second roller 31, and the side of the anti-skid column 37 away from the rotation axis of the second roller 31 is a plane. When the arc surface 36 on the slide bar 34 contacts the ground, the anti-skid column 37 also contacts the ground. The plane of the anti-skid column 37 contacts the ground. When used on the road, the contact area and friction between the second roller 31 and the road can be increased to prevent sliding. When pushing the support mechanism 2 on the ground, the anti-skid column 37 can increase the friction between the second roller 31 and the soil to prevent slipping, thereby ensuring the smooth movement of the support mechanism 2 and further maintaining the stability of the support mechanism 2 in different scenarios.

[0046] like Figure 8 and Figure 9 As shown, in this embodiment, both ends of the slide bar 34 are provided with inclined surfaces 35, and the connection between the inclined surfaces 35 and the curved surface 36 is provided with a circular chamfer. The inclined surfaces 35 and the circular chamfer design at the ends of the slide bar 34 can prevent the sharp edges at the ends of the slide bar 34 from hindering its horizontal movement on the ground and the road surface, avoid getting stuck during the movement of the slide bar 34, and ensure that the slide bar 34 is stably extended or retracted. In addition, when the slide bar 34 retracts into the trapezoidal notch 33, the inclined surface 35 can squeeze out the soil stuck in the trapezoidal notch 33. The inclination angle of the inclined surface 35 is used to decompose the extrusion force of the soil into a positive pressure perpendicular to the inclined surface 35 and a tangential force parallel to the inclined surface 35. The positive pressure separates the soil from the inner wall of the trapezoidal notch 33, and the tangential force pushes the soil to be discharged along the inclined surface 35. At the same time, the inner wall of the trapezoidal notch 33 scrapes off the soil attached to the side of the slide bar 34, thereby achieving automatic cleaning.

[0047] like Figure 7 As shown, in this embodiment, the outer wall of the limit sleeve 28 is a regular polygon, the shape of the guide sleeve 27 is adapted to the shape of the limit sleeve 28, and the outer wall of the limit sleeve 28 is a regular polygon and adapted to the shape of the inner wall of the guide sleeve 27, which can prevent the guide sleeve 27 from rotating on the limit sleeve 28, ensuring that the guide sleeve 27 can only slide along the axial direction of the limit sleeve 28, so that the movable disk 29 drives the slide bar 34 to accurately extend or retract the trapezoidal notch 33 through the connecting column 38.

[0048] Working Principle: The fire hose 1 is mounted on top of the upper connecting seat 4 via a clamp. The upper connecting seat 4 and the lower connecting seat 5 use a circular shaft to adjust the pitch angle of the fire hose 1. The rotating shaft 7 of the lower connecting seat 5 rotates within the square seat 6 to adjust the horizontal angle of the fire hose 1, allowing firefighters to accurately adjust the spray direction according to the location of the hazardous chemical leak. The side panels 11 on the side of the bracket 9 are slidably connected to the square plate 12. The locking piece is unscrewed from the hole on the side of the side panel 11, and then the bracket 9 is moved up or down to adjust the height of the bracket 9, thereby adjusting the height of the fire hose 1. After adjusting to the appropriate height, the locking piece is screwed into the corresponding hole at this time to fix the height of the bracket 9, thereby adapting it to the use of firefighters of different heights.

[0049] When the fire hose 1 sprays liquid neutralizer, part of the reaction force generated is transmitted to the base plate 10 through the bracket 9, and then transmitted to the ground through the roller 2 31 at the bottom of the base plate 10, effectively reducing the body load of the firefighter, alleviating the firefighter's labor intensity, and ensuring their continuous handling ability of dangerous situations, making it suitable for large-scale leakage of hazardous chemicals. When the fire hose 1 sprays liquid neutralizer, the firefighter holds the fire hose 1 with one hand to control the spraying angle and holds the fire hose with the other hand. The firefighter's feet are respectively on the pedal 13 on the base plate 10 and the ground. The pedal 13 is higher on the side facing the water spraying direction, forming a support surface that matches the direction of reaction force transmission. , using the downward pressure component formed by the inclination angle of the pedal 13 and the pedaling pressure, the baffle 14 limits the foot to prevent the foot from escaping, ensuring stable downward pressure on the base plate 10, effectively preventing the base plate 10 from tilting upward under the reaction force, and enhancing the anti-tilting ability of the support mechanism 2. When stepping on the pedal 13, the pedal 13 rotates downward, and the pedal 13 drives the vertical rod 16 to move downward through the roller 17. The vertical rod 16 pushes the connecting plate 18 to move downward, the tension spring 19 is stretched, and the connecting plate 18 drives the movable plate 20 to move downward along the outer wall of the sliding sleeve 24. The movable plate 20 drives the locking block 23 to move downward and fit closely with the wheel axle 32, thereby locking the roller 2 31;

[0050] When the movable plate 20 moves downward with the connecting plate 18, the inclined inner wall of one side of the inclined groove 22 squeezes the columnar block 21, causing the sliding sleeve 24 to move on the wheel shaft 32 toward the second roller 31. The sliding sleeve 24 drives the round cover 26 to move through the connecting strip 25. The round cover 26 drives the guide sleeve 27 to slide on the limit sleeve 28 toward the second roller 31 through the bearing. The guide sleeve 27 pushes the movable plate 29 to move. The movable plate 29 drives the slide bar 34 to extend from the trapezoidal notch 33 of the second roller 31 through the connecting column 38, increasing the width and support area of ​​the second roller 31. After the slide bar 34 extends from the trapezoidal notch 33, the locking block 23 fits tightly with the wheel shaft 32. After the slide bar 34 extends from the trapezoidal notch 33, the arc surface 36 of the adjacent two slide bars 34 contacts the ground. The plane formed between the two arc surfaces 36 enhances the contact stability of the rolling assembly 30 with the road surface, preventing the second roller 31 from rotating and achieving stable support.

[0051] When used on the road, after the slide bar 34 is extended, the arc surface 36 is in contact with the road surface, and the flat surface of the anti-skid column 37 is also in contact with the road surface, increasing the contact area and friction between the roller 2 31 and the road surface to prevent sliding;

[0052] When hazardous chemicals leak onto the ground, the support mechanism 2 moves to the ground, and the slide bar 34 extends to expose the trapezoidal notch 33. Due to the structural characteristics of the large gap between the trapezoidal notch 33 on the second roller 31 and the adjacent slide bar 34, after stepping on the pedal 13, the solid part of the outer wall of the second roller 31 corresponding to the adjacent trapezoidal notch 33 is inserted into the soil synchronously with the slide bar 34, and the soil interlocking resistance is used to enhance the anti-slip ability of the support mechanism 2, ensuring the stable use of the support mechanism 2 on the ground. The anti-slip column 37 on the ground can increase the friction between the second roller 31 and the soil, preventing slipping during pushing, and ensuring the smooth movement of the support mechanism 2;

[0053] When the support mechanism 2 is moved on the ground, the pedal 13 is released, the tension spring 19 is reset, and the connecting plate 18 and the movable plate 20 are driven to move upward. After the movable plate 20 moves upward, it drives the inclined inner wall of the other side of the inclined groove 22 to squeeze the columnar block 21, so that the sliding sleeve 24 moves along the wheel shaft 32 away from the second roller 31. The sliding sleeve 24 drives the guide sleeve 27 to move in the opposite direction along the limit sleeve 28 through the connecting bar 25 and the round cover 26, so that the movable plate 29 drives the slide bar 34 to move in the opposite direction through the connecting column 38 and retract into the trapezoidal notch 33. The slide bar 34 The inclined surface 35 and the vertical surface at the end cooperate with the inner wall of the trapezoidal notch 33 to squeeze out the soil stuck in the trapezoidal notch 33. The inclination angle of the inclined surface 35 is used to decompose the extrusion force of the soil into a positive pressure perpendicular to the inclined surface 35 and a tangential force parallel to the inclined surface 35. The positive pressure separates the soil from the inner wall of the trapezoidal notch 33, and the tangential force pushes the soil out along the direction of the inclined surface 35, thereby facilitating the extrusion of the soil from the trapezoidal notch 33. At the same time, the inner wall of the trapezoidal notch 33 scrapes off the soil attached to the side of the slide bar 34, realizing automatic cleaning and preventing soil residue The sliding bar 34 is affected by the subsequent movement of the support mechanism 2. After the support mechanism 2 is moved to the target position on the ground, the pedal 13 is stepped on again to make the sliding bar 34 extend from the trapezoidal notch 33, and the stable support of the support mechanism 2 and the fire hose 1 can be achieved again. The sliding bar 34 automatically cleans the soil in the trapezoidal notch 33 to prevent the soil in the trapezoidal notch 33 from affecting the subsequent insertion of the outer wall of the roller 2 31 into the soil again. When the soil stuck in the trapezoidal notch 33 is compressed and in a compact state, the sliding bar 34 cannot be retracted to the trapezoidal notch 33. When the fire hose is in the gap 33, the user can step on the top position of the baffle 14 with his foot and rotate the bracket 9 to tilt the side of the bracket 9 corresponding to the spraying direction of the fire hose 1. After tilting, the roller 2 31 is separated from the ground. After tilting, the bottom of the baffle 14 is in contact with the ground to form a fulcrum. At this time, the slide 34 is separated from the ground. When the slide 34 retracts, it is not affected by the ground resistance, ensuring that the tension of the tension spring 19 is fully applied to the retraction action of the slide 34, increasing the power of the slide 34 when it retracts, and ensuring that the slide 34 can stably squeeze out the soil stuck in the trapezoidal gap 33.

[0054] After the support mechanism 2 is moved to the target position on the ground, the pedal 13 is stepped on again, so that the slide bar 34 extends from the trapezoidal notch 33, and the support mechanism 2 and the fire hose 1 can be stably supported again.

[0055] The inclined surface 35 and the rounded chamfer design at the end of the slider 34 prevent the sharp edges at the end of the slider 34 from hindering the horizontal movement of the slider 34 on the ground and the road surface when the pedal 13 is pressed to move the slider 34 horizontally, thereby preventing the slider 34 from getting stuck during the movement and ensuring the stable horizontal movement of the slider 34 on the ground and the road surface.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
