Description

Technical Field

[0001] This invention relates to the field of emergency response devices, and more specifically to an emergency response device for hazardous chemical accidents. Background Technology

[0002] Hazardous chemicals refer to highly toxic chemicals and other chemicals that have properties such as toxicity, corrosiveness, explosiveness, flammability, and combustion-supporting, and are harmful to human health, facilities, and the environment. Chemical liquids are also a type of hazardous chemical. When a leak occurs, it needs to be dealt with promptly. Since different types of chemical liquids require different treatment media, the treatment methods also vary greatly.

[0003] The existing processing devices have the following shortcomings: 1. The emergency response function of the existing equipment is relatively simple. It can generally only handle the same type of leaked chemical liquid and cannot effectively handle different types of leaked chemical liquid. The practicality and flexibility of the equipment need to be improved.

[0004] 2. Existing devices typically use suspended sand tanks to bury and cover leaked liquids. However, due to the large suspension height of the sand tanks, the sand is easily affected by wind during the pouring process, causing it to scatter. This not only reduces the accuracy of the burial but also leads to waste. Summary of the Invention

[0016] The beneficial effects of this invention are: 1. This invention designs a spraying mechanism, namely a squeezing component, a telescopic component, a rotating component, two storage tanks, and several atomizing nozzles. The two storage tanks 19 are pre-filled with alcohol-resistant foam and a neutralizing agent, respectively. The alcohol-resistant foam can eliminate ignition sources and suppress vapors by covering them with foam. It is suitable for emergency treatment of flammable chemical liquids, such as gasoline and acetone. The neutralizing agent is mainly for corrosive chemical liquids. It uses soda ash to neutralize acidic substances or dilute acetic acid to neutralize alkaline substances, so as to achieve emergency treatment of leaked sulfuric acid or liquid alkali. This allows the device to spray alcohol-resistant foam and neutralizing agent according to the type of leaked chemical liquid, thereby meeting the emergency treatment efficiency of different types of leaked chemical liquids and improving the flexibility and practicality of the device.

[0017] 2. This invention, by designing a connecting pipe and two solenoid valves, allows for rapid changes in the treatment medium of the leaking liquid being delivered to the filling pipe by switching the opening and closing states of the two solenoid valves. This speeds up the switching process and improves the treatment efficiency for different types of leaking chemical liquids.

[0018] 3. This invention designs a burial mechanism, namely a square enclosure, a sand storage tank, a lifting plate, a drive assembly, and an angle adjustment assembly. The drive assembly drives the lifting plate to descend vertically to approach the square opening, thereby reducing the dumping height of the sand and reducing the wind force affecting the sand when it is dumped into the square opening. This prevents the sand from scattering during the dumping process, improves the accuracy of burial, and avoids waste.

[0019] 4. This invention, through the design of an angle adjustment component, enables the burial of leaked chemical liquids sprayed with solvent-resistant foam or neutralizing agents with sand. The controller activates the first electric push rod 25, causing its output end to extend and retract. Since its output end is fixedly connected to the insertion rod 26, one end of the swing rod 27 is fixedly connected to the sand storage tank 12 via the connecting rod 28. The insertion rod 26 is inserted into the clearance groove at the other end of the swing rod 27. The sand storage tank 12 is rotatably connected to the lifting plate 13 via the first rotating shaft 16. Combined with the guiding action of the limiting rod 29, the guide plate 30, and the arc-shaped guide groove, the sand storage tank 12 swings left and right, thereby changing the direction of sand pouring. This allows for rapid burial of the leaked liquid within the square enclosure 11, preventing diffusion and improving burial efficiency.

[0020] 5. This invention, through the design of a triggering mechanism, enables the coordinated operation of the burial mechanism and the spraying mechanism. Specifically, as the sand storage tank descends towards the square opening, several atomizing nozzles simultaneously spray the corresponding treatment medium onto the leaking liquid within the square enclosure. When the sand outlet pipe descends to near the square opening, the telescopic component pulls several atomizing nozzles out from above the square opening, the spraying of the treatment medium stops, and the sand is immediately dumped and buried. This ensures that the burial and spraying operations proceed smoothly, improving the high degree of coordination between the two mechanisms and thus enhancing the efficiency of emergency response to hazardous chemicals.

Detailed Implementation

[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0024] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual pictures. They should not be construed as limiting the invention. To better illustrate the embodiments of the invention, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual product dimensions.

[0025] Reference Figures 1 to 12 As shown, an emergency response device for hazardous chemical accidents includes a mounting plate 10. The mounting plate 10 has four screw holes at its four corners. The mounting plate 10 is used to install the device on an existing electric trolley through the four screw holes. The electric trolley can then drive the device to the scene for emergency response, eliminating the need for personnel to go to the scene in person, reducing safety hazards, saving time, and improving efficiency. It should be noted that the electric trolley is also designed with a notch for sand to fall into. The shape of the notch is the same as the square notch 14, which prevents sand from falling onto the electric trolley during burying. It also includes burial mechanisms, spraying mechanisms, and triggering mechanisms; The burial mechanism is located on the top of the mounting plate 10. The burial mechanism includes a square enclosure 11, a sand storage tank 12, a lifting plate 13, a drive assembly, and an angle adjustment assembly. A square notch 14 is provided on the top of the mounting plate 10. Four sliding grooves are symmetrically arranged inside the square notch 14. The square enclosure 11 is slidably disposed between the four sliding grooves via four sliding strips 15. The drive assembly is located on the top of the mounting plate 10. The lifting plate 13 is disposed on the drive assembly. The angle adjustment assembly is disposed on the lifting plate 13. The sand storage tank 12 is movably disposed on the outer wall of the lifting plate 13 via a first rotating shaft 16. The triggering mechanism is located on the mounting plate 10. The triggering mechanism includes a pressure rod 17 and a reciprocating sliding assembly. The pressure rod 17 is fixed to the outer wall of the lifting plate 13 by a pressure plate 18, and the reciprocating sliding assembly is located on the top of the mounting plate 10. The spraying mechanism is mounted on the mounting plate 10. The spraying mechanism includes a squeezing assembly, a telescopic assembly, a rotating assembly, two storage tanks 19, and several atomizing nozzles 20. Two vertical plates are fixedly mounted on the top of the mounting plate 10, and a horizontal plate is fixedly mounted between the two vertical plates. The squeezing assembly is located on the top of the horizontal plate, and the rotating assembly is located between the squeezing assembly and the reciprocating sliding assembly. The two storage tanks 19 are respectively fixedly mounted on the top of the two vertical plates. The telescopic assembly is located on the top of the mounting plate 10, and several atomizing nozzles 20 are symmetrically arranged on the telescopic assembly.

[0026] Reference Figures 1 to 12 As shown, the drive assembly includes a drive motor 21, a lead screw 22, a lifting block 23, and two sliders 24. A base plate is fixedly mounted on the top of the mounting plate 10, and a top plate is fixedly mounted on the top of the base plate via two guide posts. Each slider 24 is slidably mounted on the outer wall of a guide post. The lead screw 22 is rotatably mounted between the base plate and the top plate. The lifting block 23 is threadedly connected to the outer wall of the lead screw 22. The lifting block 23 and the two sliders 24 are all fixedly connected to one end of the lifting plate 13. The drive motor 21 is fixedly mounted on the top of the top plate, and its output end is fixedly connected to the top end of the lead screw 22 via a coupling. When the leakage point is blocked by the square enclosure 11, the drive motor 21 is started by the controller, thereby causing its output end to drive the lead screw 22 to rotate. Since each slider 24 is slidably connected to a guide post, the base plate and the top plate are rotatably connected to both ends of the lead screw 22, and the lifting block 23 is threadedly connected to the lead screw 22, the lifting block 23 and the two sliders 24 are all fixedly connected to one end of the lifting plate 13, thereby causing the lifting plate 13 to descend vertically.

[0027] Reference Figures 1 to 12As shown, the angle adjustment assembly includes a first electric push rod 25, an insert rod 26, a swing rod 27, and a connecting rod 28. The connecting rod 28 is fixedly mounted on the top of the sand storage tank 12, and the swing rod 27 is fixedly mounted on the end of the connecting rod 28 away from the sand storage tank 12. The first electric push rod 25 is hinged to the top of the lifting plate 13, and the insert rod 26 is fixedly mounted on the output end of the first electric push rod 25. A clearance groove is provided at the end of the swing rod 27 away from the connecting rod 28, and the insert rod 26 is inserted into the clearance groove. A limiting rod 29 is fixedly mounted on the bottom of the sand storage tank 12, and a guide plate 30 is fixedly mounted on the bottom of the lifting plate 13. An arc-shaped guide groove is provided on the outer wall of the guide plate 30, and the limiting rod 29 is inserted into the arc-shaped guide groove. When burying leaked chemical liquids that have been sprayed with solvent-resistant foam or neutralizing agents with sand, the controller activates the first electric push rod 25, causing its output end to extend and retract. Since its output end is fixedly connected to the insertion rod 26, one end of the swing rod 27 is fixedly connected to the sand storage tank 12 through the connecting rod 28. The insertion rod 26 is inserted into the clearance groove at the other end of the swing rod 27. The sand storage tank 12 is rotatably connected to the lifting plate 13 through the first rotating shaft 16. With the guiding action of the limit rod 29, the guide plate 30, and the arc-shaped guide groove, the sand storage tank 12 swings left and right, thereby changing the pouring direction of the sand and soil, so as to quickly bury the leaked liquid in the square enclosure 11, prevent its spread, and improve the burial efficiency.

[0028] Reference Figures 1 to 12As shown, the reciprocating sliding assembly includes a docking block 31, a sliding tooth 32, a guide rod 33, and a return spring 34. The guide rod 33 is fixedly mounted on the top of the mounting plate 10. The sliding tooth 32 is sleeved on the outer wall of the guide rod 33, and the interior of the sliding tooth 32 is provided with an insertion hole 35 for the guide rod 33 to be inserted. The top of the mounting plate 10 is fixedly provided with a slide rail 36, and the sliding tooth 32 is slidably connected to the slide rail 36. The return spring 34 is sleeved on the outer wall of the guide rod 33, and the bottom of the sliding tooth 32 and the top of the mounting plate 10 respectively abut against the two ends of the return spring 34. The docking block 31 is fixedly mounted on the top of the sliding tooth 32, and the top of the docking block 31 is provided with a groove for the pressure rod 17 to be inserted. When the lifting plate 13 descends vertically until the pressure rod 17 at the bottom of the pressure plate 18 just contacts the groove, the sand outlet pipe 60 is still some distance away from the square notch 14. At this time, the height does not meet the requirements for sand and soil to fall and bury, because the sand outlet... If the distance between pipe 60 and the square gap 14 is large, the falling sand cannot immediately bury the leaking liquid at the leak point, resulting in inaccurate burial. At the same time, the falling sand will be affected by the wind and will be scattered everywhere, resulting in a sharp reduction in the amount of sand falling into the square gap 14, thus causing waste. Since the connecting block 31 is fixedly connected to the sliding tooth 32 and the sliding tooth 32 is slidably connected to the guide rod 33, the sliding tooth 32 has a groove designed inside for the guide rod 33 to be inserted. Therefore, when the pressure rod 17 continues to descend with the lifting plate 13, the pressure rod 17 touches the connecting block 31 downward, so that the sliding tooth 32 slides vertically down on the outer wall of the guide rod 33 from the initial state. At the same time, it drives the return spring 34 to change from the initial state to the tense state. The slide rail 36, together with the guide rod 33, provides double limit for the sliding tooth 32, thereby ensuring that the sliding tooth 32 can slide smoothly vertically when it is touched.

[0029] Reference Figures 1 to 12 As shown, the rotating assembly includes a gear 37, a transmission rod 38, a driving wheel 39, a driven wheel 40, and a belt 41. The transmission rod 38 is rotatably mounted on the top of the mounting plate 10 via two support plates. A mounting block is fixed on the bottom outer wall of the sliding gear 32. The gear 37 is rotatably mounted on the mounting block via a second rotating shaft 42. The driving wheel 39 is fixed at the end of the second rotating shaft 42 away from the gear 37, and the gear 37 meshes with the sliding gear 32. The driven wheel 40 is fixed at one end of the transmission rod 38, and the belt 41 is sleeved on the driving wheel 39 and the driven wheel 40. Between the driving wheels 40, as the sliding teeth 32 slide vertically down the outer wall of the guide rod 33 from the initial state, the transmission rod 38 is rotatably connected to the mounting plate 10 through two support plates, the gear 37 is rotatably connected to the mounting block through the second rotating shaft 42, the driving wheel 39 is fixedly connected to the end of the second rotating shaft 42 away from the gear 37, the gear 37 is meshed with the sliding teeth 32, the driven wheel 40 is fixedly connected to one end of the transmission rod 38, and the driving wheel 39 and the driven wheel 40 are connected by a belt 41, thereby driving the gear 37 to rotate several times.

[0030] Reference Figures 1 to 12As shown, the extrusion assembly includes a turntable 43, a connecting rod 44, a receiving cylinder 45, an extrusion rod 46, and a sliding column 47. The turntable 43 is fixedly mounted on the end of the transmission rod 38 away from the driven wheel 40. The receiving cylinder 45 is fixedly mounted on the top of the horizontal plate. The extrusion rod 46 is inserted into the receiving cylinder 45. A slide rail is fixedly mounted on the top of the horizontal plate. The sliding column 47 is slidably mounted on the top of the slide rail. The connecting rod 44 is hinged between the turntable 43 and the sliding column 47. The sliding column 47 is fixedly connected to the extrusion rod 46. An arc-shaped baffle 48 is fixedly mounted on the end of the extrusion rod 46 away from the sliding column 47. An arc-shaped through groove is provided on the outer wall of the receiving cylinder 45 near the sliding column 47 for the arc-shaped baffle 48 to pass through. When the gear 37 rotates several times... Since the turntable 43 is fixedly connected to the end of the transmission rod 38 away from the driven wheel 40, the receiving cylinder 45 is fixedly connected to the horizontal plate, the extrusion rod 46 is inserted into the receiving cylinder 45, the sliding column 47 is slidably connected to the top of the slide rail, the edge of the turntable 43 and the side wall of the sliding column 47 are respectively hinged to the two ends of the connecting rod 44, and the sliding column 47 is fixedly connected to the extrusion rod 46, the extrusion rod 46 slides towards the end of the sliding column 47 inside the receiving cylinder 45 and then resets, and repeats this sliding process several times, that is, it drives the arc-shaped baffle 48 to move away from below the liquid inlet and then resets, thereby causing the filling tube 50 to open and close first and then close, and repeats this process several times. The arc-shaped through groove facilitates the arc-shaped baffle 48 to slide out.

[0031] Reference Figures 1 to 12 As shown, each storage tank 19 has a discharge port at its bottom, and a connecting pipe 49 is fixedly installed between the bottoms of the two discharge ports. The receiving cylinder 45 has a liquid inlet on its outer wall near the arc-shaped baffle 48, and a filling tube 50 is fixedly installed at the top of the liquid inlet. The top of the filling tube 50 is fixedly connected to the connecting pipe 49. Two solenoid valves 51 are fixedly installed on the outer wall of the connecting pipe 49, and the filling tube 50 is located between the two solenoid valves 51. It should be noted that the two storage tanks 19 are pre-filled with solvent-resistant foam and a neutralizing agent, respectively. When the filling tube 50 repeatedly opens and closes, one of the solenoid valves 51 is activated by the controller and kept open. The other solenoid valve 51 is closed. Since each storage tank 19 is designed with a drain outlet at the bottom, the bottom of the two drain outlets are respectively connected to the two ends of the connecting pipe 49. The receiving tube 45 is designed with a liquid inlet on the outer wall of the end near the arc-shaped baffle 48. The top end of the filling tube 50 is fixedly connected to the connecting pipe 49. Both solenoid valves 51 are fixedly connected to the connecting pipe 49. The filling tube 50 is located between the two solenoid valves 51, so that the alcohol-resistant foam or neutralizing agent in one of the storage tanks 19 enters the interior of the receiving tube 45 from one end of the connecting pipe 49 and the filling tube 50 in sequence, and is then pushed out by the squeezing rod 46 into the interior of the hose 57.

[0032] Reference Figures 1 to 12As shown, the telescopic assembly includes a second electric push rod 53, an extension rod 54, and a sliding plate 55. A support plate is fixedly mounted on the top of the mounting plate 10. The second electric push rod 53 is inserted into the outer wall of the support plate. The extension rod 54 is fixedly mounted on its output end. The sliding plate 55 is fixedly mounted on the end of the extension rod 54 away from the second electric push rod 53. Two guide rails are fixedly mounted on the top of the support plate. The sliding plate 55 is slidably mounted between the two guide rails via two sliding rods 56. The receiving cylinder 45 has a liquid outlet at the end away from the sliding column 47. A flexible hose 57 is fixedly mounted at one end of the liquid outlet. A one-way valve 52 is fixedly installed at one end of the receiving cylinder 45. Several branch pipes 58 are fixedly installed on the top of the slide plate 55. Each branch pipe 58 is fixedly connected to an atomizing nozzle 20. A diversion pipe 59 is fixedly installed between the ends of the branch pipes 58 away from the atomizing nozzle 20. The end of the hose 57 away from the receiving cylinder 45 is fixedly connected to the diversion pipe 59. When the alcohol-resistant foam or neutralizing agent in one of the storage tanks 19 enters the interior of the receiving cylinder 45 through one end of the connecting pipe 49 and the filling pipe 50, it is then pushed out to the hose 57 by the squeezing rod 46. Inside, the receiving cylinder 45 has a liquid outlet at the end furthest from the sliding column 47. This outlet is fixedly connected to the hose 57. The top of the sliding plate 55 is fixedly connected to several branch pipes 58, each branch pipe 58 being fixedly connected to an atomizing nozzle 20. A diversion pipe 59 is fixedly designed between the ends of the branch pipes 58 furthest from the atomizing nozzle 20. The end of the hose 57 furthest from the receiving cylinder 45 is fixedly connected to the diversion pipe 59. This allows alcohol-resistant foam or neutralizing agent to be sprayed from the atomizing nozzles 20, spraying the leaked liquid. Specifically, the alcohol-resistant foam... Soluble foam can eliminate ignition sources and suppress vapors by covering them with foam. It is suitable for emergency treatment of flammable chemical liquids such as gasoline and acetone. Neutralizing agents are mainly for corrosive chemical liquids. They use soda ash to neutralize acidic substances or dilute acetic acid to neutralize alkaline substances, in order to achieve emergency treatment of leaked sulfuric acid or liquid alkali. When the spraying is finished, the controller activates the second electric push rod 53, which causes its output end to retract. Then, through the extension rod 54, the slide plate 55 moves out from above the square notch 14, providing clearance for the continued descent of the sand outlet pipe 60.

[0033] Reference Figures 1 to 12As shown, a sand outlet pipe 60 is fixedly installed at the bottom of the sand storage tank 12, and an electric slide valve 61 is fixedly installed on the outer wall of the sand outlet pipe 60. An injection pipe 62 is fixedly installed at the top of the sand outlet tank. When the slide plate 55 moves several atomizing nozzles 20 out from above the square notch 14, the lifting plate 13 drives the sand storage tank 12 to continue to descend until the sand outlet pipe 60 is close to the square notch 14 and stops. The controller cuts off the power to drive the motor 21, thereby stopping the rotation of the screw 22, so that the lifting plate 13 stops descending. At the same time, the spraying work is immediately interrupted. At this time, the controller starts the electric slide valve 61, thereby opening the sand outlet pipe. Opening the gate at 60 allows sand pre-stored in the sand storage tank 12 to fall through the square opening 14 into the interior of the square enclosure 11, burying any leaked liquid within the enclosure 11. Firstly, the porous structure of the sand absorbs some of the leaked chemical liquid, reducing its free flow and diffusion area on the ground. It also prevents it from flowing into sewers, drainage ditches, soil, or sensitive areas such as water sources. Furthermore, it reduces the diffusion of corrosive, flammable, or odorous gases into the air, lowering the risk of explosion and environmental pollution. Secondly, it effectively prevents accidental trampling or contact by personnel, facilitating subsequent cleanup.

[0034] Reference Figures 1 to 12 As shown, a third electric push rod 63 is fixedly installed on the top of the mounting plate 10, and a push block 64 is fixedly installed on its output end. A transition rod 65 is fixedly installed between the bottom of the push block 64 and the top of the square enclosure 11. This device is equipped with a controller. The electric trolley and all electrical equipment on this device are electrically connected to the controller. A camera (not shown) is fixedly installed on the bottom of the electric trolley. When the electric trolley drives this device to the top of the leak point, that is, when the camera detects the leak point, the controller adjusts the position of the electric trolley until the leak point is below the square notch 14. First, the controller cuts off the power to the electric trolley to stop it from continuing to move. Then, the controller starts the third electric push rod 63, thereby causing its output end to retract. Since the output end of the device is fixedly connected to the square enclosure 11 through the push block 64 and the transition rod 65, and the square enclosure 11 is slidably connected to the square notch 14 through four slide bars 15, the square enclosure 11 is vertically lowered on the mounting plate 10 until the bottom of the square enclosure 11 is lowered to fit against the ground, thus achieving the enclosure of the leak point.

[0035] The working principle of this invention: The mounting plate 10 is installed with the existing electric trolley through four screw holes, so that the electric trolley can drive the processing device to the site for emergency treatment, eliminating the need for personnel to go to the site in person, reducing safety hazards, saving time and improving processing efficiency. It should be noted that the electric trolley is also designed with a notch for sand to fall into, and the shape of the notch is the same as the square notch 14, to prevent sand from falling onto the electric trolley when burying sand. This device is equipped with a controller. The electric trolley and all electrical equipment on this device are electrically connected to the controller. A camera (not shown) is fixedly installed at the bottom of the electric trolley. When the electric trolley drives this device to a position above the leak point, i.e., when the camera detects the leak point, the controller adjusts the position of the electric trolley until the leak point is below the square notch 14. First, the controller cuts off the power to the electric trolley to stop it from continuing to move. Then, the controller activates the third electric push rod 63, causing its output end to retract. Since the output end of the device is fixedly connected to the square enclosure 11 through the push block 64 and the adapter rod 65, and the square enclosure 11 is slidably connected to the square notch 14 through four sliding strips 15, the square enclosure 11 descends vertically on the mounting plate 10 until the bottom of the square enclosure 11 descends to be flush with the ground, thus containing the leak point.

[0036] After the leak point is blocked by the square enclosure 11, the drive motor 21 is started by the controller, so that its output end drives the lead screw 22 to rotate. Since each slider 24 is slidably connected to a guide post, the bottom plate and the top plate are rotatably connected to the two ends of the lead screw 22 respectively. The lifting block 23 is threadedly connected to the lead screw 22. The lifting block 23 and the two sliders 24 are fixedly connected to one end of the lifting plate 13, thereby driving the lifting plate 13 to descend vertically.

[0037] When the lifting plate 13 descends vertically until the pressure rod 17 at the bottom of the pressure plate 18 just contacts the groove, the sand outlet pipe 60 is still some distance from the square notch 14. At this point, the height is insufficient to meet the requirements for sand burial. If the distance between the sand outlet pipe 60 and the square notch 14 is too large, the falling sand cannot immediately bury the leaking liquid at the leak point, resulting in inaccurate burial. Furthermore, the falling sand is also affected by wind and will scatter, causing a sharp decrease in the amount of sand falling into the square notch 14, thus resulting in waste. Block 31 is fixedly connected to slide tooth 32, and slide tooth 32 is slidably connected to guide rod 33. The interior of slide tooth 32 is designed with a groove for guide rod 33 to be inserted. Therefore, when pressure rod 17 continues to descend with lifting plate 13, pressure rod 17 abuts against block 31, causing slide tooth 32 to slide vertically down on the outer wall of guide rod 33 from the initial state. At the same time, it drives return spring 34 to change from the initial state to the tensile state. Slide track 36, together with guide rod 33, provides double limit for slide tooth 32, thereby ensuring that slide tooth 32 can slide smoothly vertically when abutted.

[0038] As the sliding tooth 32 slides vertically down the outer wall of the guide rod 33 from its initial state, the transmission rod 38 is rotatably connected to the mounting plate 10 through two support plates, the gear 37 is rotatably connected to the mounting block through the second rotating shaft 42, the driving wheel 39 is fixedly connected to the end of the second rotating shaft 42 away from the gear 37, the gear 37 is meshed with the sliding tooth 32, the driven wheel 40 is fixedly connected to one end of the transmission rod 38, and the driving wheel 39 and the driven wheel 40 are connected by a belt 41, thereby driving the gear 37 to rotate several times.

[0039] When gear 37 rotates several times, the turntable 43 is fixedly connected to the end of transmission rod 38 away from driven wheel 40, receiving cylinder 45 is fixedly connected to horizontal plate, extrusion rod 46 is inserted into receiving cylinder 45, sliding column 47 is slidably connected to the top of slide rail, the edge of turntable 43 and the side wall of sliding column 47 are respectively hinged to the two ends of connecting rod 44, and sliding column 47 is fixedly connected to extrusion rod 46. Thus, extrusion rod 46 slides towards the end of sliding column 47 inside receiving cylinder 45 and then resets, repeating this sliding process several times. That is, it drives arc-shaped baffle 48 to move away from below the liquid inlet and then resets, thereby causing filling tube 50 to open and close first and then close, repeating this process several times. Arc-shaped through groove facilitates arc-shaped baffle 48 to slide out.

[0040] It should be noted that the two storage tanks 19 are pre-filled with alcohol-resistant foam and neutralizing agent, respectively. When the filling tube 50 is repeatedly opened and closed, one of the solenoid valves 51 is activated by the controller while the other solenoid valve 51 remains closed. Since each storage tank 19 is designed with a discharge port at the bottom, the bottom of the two discharge ports are respectively connected to both ends of the connecting tube 49. The receiving tube 45 is designed with a liquid inlet on the outer wall of the end near the arc-shaped baffle 48. The top end of the filling tube 50 is fixedly connected to the connecting tube 49. Both solenoid valves 51 are fixedly connected to the connecting tube 49. The filling tube 50 is located between the two solenoid valves 51, so that the alcohol-resistant foam or neutralizing agent in one of the storage tanks 19 enters the interior of the receiving tube 45 from one end of the connecting tube 49 and the filling tube 50 in sequence, and is then pushed out into the interior of the hose 57 by the squeezing rod 46.

[0041] When the alcohol-resistant foam or neutralizing agent in one of the storage tanks 19 enters the receiving cylinder 45 sequentially from one end of the connecting pipe 49 and the filling pipe 50, and is then pushed out into the hose 57 by the squeezing rod 46, the receiving cylinder 45 has an outlet at the end away from the sliding column 47, which is fixedly connected to the hose 57. The top of the slide plate 55 is fixedly connected to several branch pipes 58, each of which is fixedly connected to an atomizing nozzle 20. A diversion pipe 59 is fixedly designed between the ends of the branch pipes 58 away from the atomizing nozzle 20. The end of the hose 57 away from the receiving cylinder 45 is fixedly connected to the diversion pipe 59, thereby allowing the alcohol-resistant foam to... Alternatively, a neutralizing agent can be sprayed from several atomizing nozzles 20 to spray the leaked liquid. Specifically, the alcohol-resistant foam can eliminate the ignition source and suppress vapors by covering and suppressing them. It is suitable for emergency treatment of flammable chemical liquids, such as gasoline and acetone. The neutralizing agent is mainly for corrosive chemical liquids. It uses soda ash to neutralize acidic substances or dilute acetic acid to neutralize alkaline substances, in order to achieve emergency treatment of leaked sulfuric acid or liquid alkali. When the spraying is finished, the controller activates the second electric push rod 53, which causes its output end to retract. Then, through the extension rod 54, the slide plate 55 moves out from above the square notch 14, providing clearance space for the continued descent of the sand outlet pipe 60.

[0042] After the sliding plate 55 moves several atomizing nozzles 20 out from above the square gap 14, the lifting plate 13 drives the sand storage tank 12 to continue descending until the sand outlet pipe 60 is close to the square gap 14 and stops. The controller cuts off the power to drive the motor 21, thereby stopping the rotation of the lead screw 22, so that the lifting plate 13 stops descending. At the same time, the spraying work is immediately interrupted. At this time, the controller activates the electric slide valve 61, thereby opening the sand outlet pipe 60, allowing the sand pre-stored in the sand storage tank 12 to fall from the square gap 14 into the interior of the square enclosure 11, burying the leaked liquid in the square enclosure 11. On the one hand, the sand has a porous structure, which can absorb some of the leaked chemical liquid, reducing the free flow and diffusion area of ​​the chemical liquid on the ground, and preventing it from flowing into sewers, drainage ditches, soil or sensitive areas such as water sources. It can also reduce the diffusion of corrosive, flammable or odorous gases into the air, reducing the risk of explosion and environmental pollution. On the other hand, it can effectively prevent people from accidentally stepping on or touching it, making it convenient for later cleanup.

[0043] When burying leaked chemical liquids that have been sprayed with solvent-resistant foam or neutralizing agents with sand, the controller activates the first electric push rod 25, causing its output end to extend and retract. Since its output end is fixedly connected to the insertion rod 26, one end of the swing rod 27 is fixedly connected to the sand storage tank 12 through the connecting rod 28. The insertion rod 26 is inserted into the clearance groove at the other end of the swing rod 27. The sand storage tank 12 is rotatably connected to the lifting plate 13 through the first rotating shaft 16. With the guiding action of the limit rod 29, the guide plate 30, and the arc-shaped guide groove, the sand storage tank 12 swings left and right, thereby changing the pouring direction of the sand and soil, so as to quickly bury the leaked liquid in the square enclosure 11, prevent its spread, and improve the burial efficiency.
