DETAILED DESCRIPTION

[0041] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention are clearly and completely described. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0042] A defect of hazardous chemicals transport vehicles in the prior art is that, during the transportation of hazardous chemicals, if the transport tank collides or shakes violently, it is very easy to cause the hazardous chemicals transferred in the transport tank to become unstable, thereby causing leakage of hazardous chemicals and triggering safety accidents. It often takes time for rescue personnel to arrive at the scene, and the rapid dissipation of hazardous chemicals in a short period of time will cause uncontrollable losses.

[0043] To solve the above problems, the main concept adopted in this embodiment is: to detect the leakage information of hazardous chemicals through the driving component, and then use the regulating component under the operation of the staff to store part of the leaked hazardous chemicals and obtain water for diluting the hazardous chemicals. Then the driving component controls the regulating component so that the leaked hazardous chemicals are stored inside the outer tank 11. On the one hand, the leakage time of hazardous chemicals is extended, which buys time for rescue personnel to arrive at the scene. On the other hand, the amount of hazardous chemical leakage is reduced. The inner tank 13 and the outer tank 11 reduce the situation where hazardous chemicals quickly escape into the air.

[0044] The present invention provides a hazardous chemicals transport vehicle, comprising a vehicle body 1, an outer tank 11 is installed at the rear of the vehicle body 1, a discharge pipe 14 is fixedly connected to the rear end of the bottom of the outer tank 11, a middle tank 12 and an inner tank 13 are sequentially arranged from the outside to the inside of the outer tank 11, the left and right sides of the middle tank 12 are fixedly connected to the inner surface of the outer tank 11, and the chamber between the outer tank 11 and the middle tank 12 is filled with water; and further comprising:

[0045] A driving assembly, the driving assembly is located at the bottom of the outer tank 11 and is used to release the water in the chamber between the outer tank 11 and the middle tank 12;

[0046] An adjusting component, which is located at the top of the middle tank 12 and is used to cooperate with the driving component and provide a temporary storage space for the hazardous chemicals leaked from the inner tank 13;

[0047] The equipment is divided into two parts: a vehicle body 1 and an outer tank 11. The outer tank 11, the middle tank 12 and the inner tank 13 are composed of an upper and lower shell. The transporter fills the inner tank 13 with hazardous chemicals through a discharge pipe 14. The hazardous chemicals here are water-dilutable substances. When the filling is saturated, the discharge pipe 14 is closed to keep the discharge pipe 14 sealed, and then the hazardous chemicals are transported normally.

[0048] When the hazardous chemicals cause damage to the inner tank 13 due to shaking, collision or chemical reaction, the hazardous chemicals enter between the middle tank 12 and the inner tank 13. Under the detection of the regulating component, the information of the hazardous chemical leakage is promptly transmitted to the transporter. At the same time, the leaked hazardous chemicals enter the middle tank 12 and continue to extend to the outer tank 11. The driving component at the outer tank 11 discharges the water in the outer tank 11 to the outside for emergency treatment. The leaked hazardous chemicals then enter the outer tank 11 for temporary storage, waiting for the arrival of rescue personnel.

[0049] In the process of transporting hazardous chemicals, if the transport tank collides or shakes violently, it is very easy to cause the hazardous chemicals transferred in the transport tank to be unstable. In the prior art, the outer tank 11 is usually thickened or the shaking of the transport vehicle is reduced by a structure, but it cannot prevent the leakage of hazardous chemicals and prolong the leakage time of hazardous chemicals. At the same time, the driver cannot know the leakage of hazardous chemicals, and it often takes time for rescue personnel to arrive at the scene. The rapid dissipation of hazardous chemicals in a short period of time will cause uncontrollable losses;

[0050] A hazardous chemical transport vehicle provided by the present invention detects hazardous chemical leakage information through a driving component, and then uses an adjusting component under the operation of a staff member to store part of the leaked hazardous chemicals and obtain a water source for diluting the hazardous chemicals. Then the driving component controls the adjusting component so that the leaked hazardous chemicals are stored inside an outer tank 11. On the one hand, the time of hazardous chemical leakage is extended, buying time for rescue personnel to arrive at the scene, and on the other hand, the amount of hazardous chemical leakage is reduced. The inner tank 13 and the outer tank 11 reduce the situation where hazardous chemicals quickly escape into the air.

[0051] As a specific embodiment of the present invention, the driving assembly includes:

[0052] A water outlet 21, wherein the water outlet 21 is provided at the bottom of the outer tank 11;

[0053] The round cover 22 is rotatably connected to the inner wall of the outer tank 11 and fits the water outlet hole 21. The round cover 22 is provided with a hole of the same size as the water outlet hole 21. After the round cover 22 is rotated, there are two states: the water outlet hole 21 corresponds to the hole on the round cover 22 and the water outlet hole 21 is misaligned with the hole on the round cover 22. The outer side of the round cover 22 is provided with gear teeth and the bottom of the side of the round cover 22 is provided with an arc groove;

[0054] The arc plate 23 passes through the outer tank 11 and is fixed to the inner wall of the round cover 22. A pipe is sleeved on the arc plate 23 and the outer wall of the arc plate 23 located below the outer tank 11 is fixed to the pipe;

[0055] The sealing cover 24 is fixed to the inside of the outer tank 11 and is sealingly and slidably connected to the round cover 22, that is, water will not enter the sealing cover 24 during the sliding process of the round cover 22;

[0056] A rotating shaft 25, wherein the rotating shaft 25 is rotatably connected to the top of the sealing cover 24 and the bottom of the outer tank 11, and the rotating shaft 25 is connected between the sealing cover 24 and the outer tank 11 through a bearing;

[0057] A first gear 251, the first gear 251 is fixed to the rotating shaft 25, and the first gear 251 is meshed with the gear teeth on the outer surface of the circular cover 22;

[0058] A second gear 252 , the second gear 252 is fixed to the rotating shaft 25 , and the second gear 252 is located below the first gear 251 ;

[0059] The rack 26 is slidably connected to the bottom of the outer tank 11. The rack 26 is meshed with the second gear 252 and one end of the rack 26 is located inside the arc groove. A groove is provided at the bottom of the outer tank 11 for the rack 26 to slide. The rack 26 is partially located inside the sealing cover 24, so the rack 26 and the sealing cover 24 are also sealed and slidably connected, thereby ensuring that water does not enter the sealing cover 24 to affect the rotation of the gear;

[0060] A slider 27, wherein the slider 27 is fixed to one end of the rack 26 away from the arc groove, and the slider 27 is slidably connected to the bottom of the outer tank 11;

[0061] The adjustment component comprises:

[0062] A through hole 31, wherein the through hole 31 is opened on the top of the middle tank 12, and the through hole 31 is located at the center of the middle tank 12;

[0063] A gas concentration sensor 32, wherein the gas concentration sensor 32 is fixedly connected to the top of the middle tank 12 and is close to the through hole 31;

[0064] A push plate 33, wherein the push plate 33 is slidably connected to both sides of the through hole 31 and the push plate 33 is sealed and slidably connected to the chambers of the outer tank 11 and the middle tank 12. The shape of the chamber is set according to the actual production convenience, so that the push plate 33 can move smoothly at the corner. A fixed block is fixedly connected to the center of the top of the outer tank 11, and the push plate 33 is separated by the fixed block.

[0065] The front end of the vehicle body 1 is fixedly connected with an alarm 4;

[0066] When hazardous chemicals leak, the leaked hazardous chemicals flow between the middle tank 12 and the inner tank 13 to the through hole 31. At this time, the gas concentration sensor 32 senses the increase in the concentration of hazardous chemicals, and then converts the chemical signal into an electrical signal, which is transmitted to the alarm and the rescue center. The alarm sends an alarm to the transporter and the surrounding environment. The rescue center quickly locates the location of the hazardous chemical transport vehicle and arranges personnel to go to the rescue. The transporter stops the vehicle in a safe and open area, and then connects the external water pipe to the pipe at the curved plate 23. Here, one implementation method is The external water pipe is connected to a pressure pump, which compresses the water flow to form a high-pressure water flow, and then dilutes the subsequent leaked hazardous chemicals with water. A rotating ring is added at the connection between the arc plate 23 and the outer tank 11. The rotating ring is fixedly connected to the arc plate 23 and is slidably connected to the outer tank 11. The staff rotates the rotating ring, which in turn drives the arc plate 23 to rotate, the arc plate 23 drives the round cover 22 to rotate, the round cover 22 drives the No. 1 gear 251 to rotate, the No. 1 gear 251 drives the rotating shaft 25 and the No. 2 gear 252 to rotate, and the No. 2 gear 252 drives the gear The strip 26 and the slider 27 move away from the round cover 22, so that the water outlet 21 corresponds to the hole on the round cover 22, and then the water flows out through the water outlet 21. At the same time, due to the reduction of water flow, negative pressure is formed inside, or the amount of hazardous chemicals leaking is too much, and the leaked hazardous chemicals push the push plate 33 to move, and then the push plate 33 at the top of the cavity of the outer tank 11 and the middle tank 12 will move along the cavity between the outer tank 11 and the middle tank 12 to the sides of the outer tank 11 first, and then move downward, so that the hazardous chemicals will be stored in the outer tank 11 and the middle tank 12. The inside of the cavity of the tank 12 prolongs the time for the hazardous chemicals to leak out of the outside, thereby delaying the rescue time for the rescue personnel; when the push plate 33 reaches the vicinity of the water outlet 21 and pushes the slider 27, the rack 26 also moves toward the water outlet 21, thereby driving the second gear 252 and the first gear 251 to rotate, thereby causing the hole on the round cover 22 to be misaligned with the water outlet 21, preventing the leaked hazardous chemicals from flowing out of the water outlet 21. Through the push plate 33, the staff can understand the leakage speed of the hazardous chemicals according to the size of the water flow, and then make an emergency response.

[0067] As a specific embodiment of the present invention, the middle tank 12 is filled with chemical adsorbent cotton;

[0068] On the one hand, the chemical adsorption cotton can reduce the amplitude of the shaking of the inner tank 13 during the transportation of hazardous chemicals, thereby achieving a shock-absorbing effect. On the other hand, it can absorb part of the hazardous chemicals when they leak, thereby reducing the amount of hazardous chemicals leaked, slowing down the leakage rate of hazardous chemicals, and extending the time for the arrival of rescue personnel.

[0069] As a specific embodiment of the present invention, the front end of the outer tank 11 is slidably connected to a support frame 5, the support frame 5 is provided with a slide groove 51, a second slider 52 is slidably connected in the slide groove 51, the second slider 52 is hinged to an electric lifting rod 6, the bottom of the electric lifting rod 6 is fixed to the vehicle body 1, so that the outer tank 11 is fixed relative to the support frame 5 during normal transportation, and the outer tank 11 can also be disassembled when it needs to be cleaned or replaced;

[0070] When the hazardous chemicals are transported to the designated location, they are discharged through the discharge pipe 14, and the discharge pipe 14 is arranged at the tail, so that the hazardous chemicals at the head of the inner tank 13 are difficult to be discharged quickly to the designated location, and the electric lifting rod 6 fixed to the vehicle body 1 rises upward, driving the second slider 52 to rise upward, and then the second slider 52 drives the support frame 5 and the front end of the outer tank 11 to rise upward, so that the head of the inner tank 13 is higher than the tail, and the hazardous chemicals flow to the tail under the influence of gravity, thereby improving the speed and efficiency of unloading.

[0071] As a specific embodiment of the present invention, a water inlet 7 is provided on the side wall of the outer tank 11, a piston is threadedly connected to the water inlet 7, and the piston is sealingly and slidably connected to the water inlet 7;

[0072] When a vehicle is driving for a long time, exposure to sunlight will cause the water to heat up and form scale. Regularly replacing the water can reduce water loss and reduce the effectiveness of preventing hazardous chemicals from leaking, while also improving the heat dissipation effect of the water.

[0073] As a specific embodiment of the present invention, the inner tank 13, the middle tank 12 and the outer tank 11 are made of stainless steel;

[0074] Stainless steel has high hardness and strong corrosion resistance, which reduces the possibility of the inner tank 13 being corroded by hazardous chemicals, reduces the possibility of the outer tank 11 and the middle tank 12 being easily broken when they collide, and improves the safety of the transportation of hazardous chemicals.

[0075] As a specific embodiment of the present invention, the outer side of the inner tank 13 is covered with a thermal insulation coating;

[0076] Some hazardous chemicals need to maintain a certain temperature during transportation to reduce the instability of the chemical properties of hazardous chemicals due to temperature changes, thereby avoiding explosions of hazardous chemicals.

[0077] As a specific embodiment of the present invention, a water level pressure sensor 8 is fixedly connected to the front end or rear end of the top of the outer tank 11;

[0078] If the outer tank 11 collides or shakes violently during transportation, it is very easy to cause the outer tank 11 to break. At this time, when the water level pressure sensor 8 changes its indication, the chemical signal is converted into an electrical signal and then transmitted to the signal receiving unit in the alarm 4, so that the transporter can sense the rupture of the outer tank 11 in time during driving, avoiding the impact of the rupture of the outer tank 11 on the storage of hazardous chemicals in the inner tank 13.

[0079] The specific workflow is as follows:

[0080] When hazardous chemicals leak, the leaked hazardous chemicals flow between the middle tank 12 and the inner tank 13 to the through hole 31. At this time, the gas concentration sensor 32 senses the increase in the concentration of hazardous chemicals, and then converts the chemical signal into an electrical signal, which is transmitted to the alarm and the rescue center. The alarm sends an alarm to the transporter and the surrounding environment. The rescue center quickly locates the location of the hazardous chemical transport vehicle and arranges personnel to go to the rescue. The transporter stops the vehicle in a safe and open area, and then connects the external water pipe to the pipe at the curved plate 23. Here, one implementation method is The external water pipe is connected to a pressure pump, which compresses the water flow to form a high-pressure water flow, and then dilutes the subsequent leaked hazardous chemicals with water. A rotating ring is added at the connection between the arc plate 23 and the outer tank 11. The rotating ring is fixedly connected to the arc plate 23 and is slidably connected to the outer tank 11. The staff rotates the rotating ring, which in turn drives the arc plate 23 to rotate, the arc plate 23 drives the round cover 22 to rotate, the round cover 22 drives the No. 1 gear 251 to rotate, the No. 1 gear 251 drives the rotating shaft 25 and the No. 2 gear 252 to rotate, and the No. 2 gear 252 drives the gear The strip 26 and the slider 27 move away from the round cover 22, so that the water outlet 21 corresponds to the hole on the round cover 22, and then the water flows out through the water outlet 21. At the same time, due to the reduction of water flow, negative pressure is formed inside, or the amount of hazardous chemicals leaking is too much, and the leaked hazardous chemicals push the push plate 33 to move, and then the push plate 33 at the top of the cavity of the outer tank 11 and the middle tank 12 will move along the cavity between the outer tank 11 and the middle tank 12 to the sides of the outer tank 11 first, and then move downward, so that the hazardous chemicals will be stored in the outer tank 11 and the middle tank 12. The inside of the cavity of the tank 12 prolongs the time for the hazardous chemicals to leak out of the outside, thereby delaying the rescue time for the rescue personnel; when the push plate 33 reaches the vicinity of the water outlet 21 and pushes the slider 27, the rack 26 also moves toward the water outlet 21, thereby driving the second gear 252 and the first gear 251 to rotate, thereby causing the hole on the round cover 22 to be misaligned with the water outlet 21, preventing the leaked hazardous chemicals from flowing out of the water outlet 21. Through the push plate 33, the staff can understand the leakage speed of the hazardous chemicals according to the size of the water flow, and then make an emergency response.
