Description

Technical Field

[0001] The invention relates to the technical field of explosion-proof, in particular to an isolated explosion-proof tank for engine transportation. Background Art

[0002] In the field of modern industry and transportation, engines, as key power equipment, often need to be transported between different locations. However, the transportation of engine explosion-proof tank parts in transport vehicles faces many challenges and safety hazards.

[0003] Traditional engine transportation methods usually use simple packaging or containers, which cannot effectively deal with various adverse factors during transportation. Among them, the problem of left and right shaking during transportation is particularly prominent. When the engine is placed in the explosion-proof tank of the transport vehicle for transportation, due to the complexity of road conditions, vehicle acceleration and deceleration, and turning operations, the explosion-proof tank of the transport vehicle will shake left and right. This shaking may not only cause mechanical damage to the engine itself, such as deformation of the outer shell due to collision, loosening of internal components, etc., but also increase the instability during transportation and may even cause safety accidents.

[0004] In addition, during the transportation of the engine, friction will be generated due to shaking. This friction will cause the temperature to rise, and the temperature increase will cause the internal pressure of the explosion-proof tank to increase. If this change in internal pressure cannot be handled promptly and effectively, it may cause damage to the explosion-proof tank or even explosion, causing serious harm to the surrounding environment and personnel.

[0005] At present, the existing explosion-proof tank components of transport vehicles have obvious deficiencies in solving the problems of left and right shaking and pressure increase during engine transportation. Some simple shock-absorbing measures can only reduce vibration to a certain extent, but the effect of suppressing left and right shaking is limited. In terms of pressure control, most containers lack the function of active pressure relief and cannot promptly respond to the situation where the internal pressure increases due to the temperature increase caused by shaking friction.

[0006] Therefore, in order to ensure the safety of the engine during transportation, improve transportation efficiency, prevent the engine from shaking left and right during transportation, and have an active pressure relief function to cope with the increase in internal pressure caused by the increase in temperature due to shaking friction, this is the main problem that needs to be solved urgently. Summary of the invention

[0007] The object of the present invention is to provide an isolated explosion-proof tank for transporting an engine, so as to solve the problems raised in the prior art.

[0008] To achieve the above object, the present invention provides the following technical solutions: The isolated explosion-proof tank for engine transportation includes a tank body, a storage unit, an anti-shake unit and a controller. The tank body includes a bracket, an inner tank and an outer tank. The bracket is placed on a horizontal basis, the bracket is fixedly connected to the outer tank, the inner tank is installed inside the outer tank, the inner tank is provided with a vent connected to the outer tank, the outer surface of the outer tank is provided with a pressure relief valve, the anti-shake unit is installed inside the outer tank, the storage unit is slidably installed inside the inner tank, the anti-shake unit is slidably connected to the storage unit, the anti-shake unit has the function of reducing the vibration of the storage unit and actively relieving the pressure of the tank body, the controller is fixedly installed on the outer tank, and the controller is electrically connected to the anti-shake unit.

[0009] The tank body is used to install the anti-shake unit and the storage unit. The storage unit is used to hold the engine. The anti-shake unit is used to prevent the storage unit from shaking to protect the engine while actively releasing the pressure inside the tank body. The controller controls the opening and closing of the anti-shake unit. When the transport vehicle is transporting the engine through a rugged road, causing the storage unit to shake greatly inside the tank body, the anti-shake unit is used to reduce the shaking of the storage unit. At the same time, it also reduces the excessive pressure caused by the increase in internal temperature due to the friction between the shaking of the storage unit and the inner wall of the tank body. When the internal temperature generated by friction is too high, the anti-shake unit will release the pressure to prevent the tank from exploding due to excessive pressure.

[0010] Furthermore, the storage unit includes a mounting frame, a storage cylinder, a support plate and an arc plate, the mounting frame is fixedly connected to the arc plate, the storage cylinder is fixedly connected to the mounting frame, one end of the support plate is fixedly connected to the mounting frame, and the other end is fixedly connected to the storage cylinder, circular holes are opened on the two support plates away from the horizontal base, and the support plate is slidably connected to the anti-shake unit.

[0011] When the engine needs to be transported, the staff puts the engine into the storage cylinder, seals it, and then places the mounting frame along the arc plate into the inner tank. The support plate passes through the slide rod and the mounting frame is fixed to the inner tank by the clamping block to ensure that the engine is stable in the tank during transportation and reduce shaking.

[0012] Furthermore, the anti-shake unit includes a slide bar, a slide plate, a moving block, a magnet, a clamping block, a small coil, a large coil, a slide bar, a guide rod, an electromagnet, a swing rod, a memory spring, a circulation pump, a holding box, a displacement sensor, a bimetallic strip, an arc rod, an electrode sheet one, an electrode sheet two, a telescopic spring and a push plate. The slide bar is slidably connected to the support plate, and both ends of the slide bar are fixedly connected to the outer tank pipe cover. The slide bar is slidably mounted on the slide bar, and the slide bar is mounted inside the inner tank. The moving block is fixedly mounted on the side of the slide bar close to the storage unit. One end of the magnet is fixedly connected to the moving block, and the other end is fixedly connected to the clamping block. There are two clamping blocks, and the two clamping blocks are clamped with the mounting frame. The small coil is evenly wound on the outer surface of the slide bar, and the large coil is evenly wound on the outer surface of the inner tank. A rectangular groove is opened at one end of the slide bar away from the mounting frame. The electromagnet is fixedly mounted on both ends of the rectangular groove of the slide bar, and both ends of the guide rod are fixedly connected to the electromagnet. The slide bar is slidably mounted on the guide rod. The cam is connected to the outer cover of the tank by a threaded cantilever cam, and the cam is connected to the bottom cover of the tank by a threaded cantilever cam, and the cam is used to hold the magnetorheological fluid, and is slidably connected to the slide bar at one end.

[0013] When the transport vehicle passes through complex road conditions or the vehicle accelerates, decelerates, and turns, causing the storage unit to shake left and right in the inner tank, when the arc plate moves to the left, it pushes the clamping block on the left to drive the magnet and the moving block to move to the left, thereby pushing the slide plate to move left along the slide rod, thereby squeezing the rocker bar to push the slide block away from each other along the guide rod while stretching the memory spring. On the one hand, when the magnet moves inside the small coil, the magnetic flux changes, thereby generating a reverse current in the small coil. The small coil transmits the current signal to the controller. According to the direction of the electrical signal, the controller does not send current to the memory spring, but sends current to the electromagnet, changing the polarity of the electromagnet so that the electromagnet and the slider are in the same direction. The same polarity pushes the slider away from the electromagnet, and under the action of the restoring force of the memory spring, they jointly resist the leftward movement of the slider, reset the slider, and prevent the arc plate from moving too much in the inner tank and causing jitter. On the other hand, when the displacement sensor detects that the moving block is moving to the left, it is judged as a negative value, and the signal is transmitted to the controller according to the size of the moving distance. The controller determines the size of the jitter of the arc plate according to the distance moved by the moving block, thereby controlling the circulation pump to deliver the volume of magnetorheological fluid to the containing box. At the same time, the controller delivers current to the large coil, thereby generating a strong magnetic field, changing the magnetorheological fluid in the containing box from low viscosity to high viscosity, preventing the slider from continuing to move to the left, and avoiding greater jitter of the mounting frame.

[0014] When the arc plate moves to the left, the clamping block on the right is pulled to drive the magnet and the moving block to move to the left, thereby pulling the right slide plate to the left along the slide rod, thereby driving the two slide blocks to move closer to each other along the guide rod while compressing the memory spring. On the one hand, when the right magnet moves inside the small coil, the magnetic flux changes synchronously, thereby generating a positive current in the small coil. The small coil transmits the current signal to the controller. When the direction of the electrical signal is a positive current, the controller transmits current to the memory spring. After receiving the current, the memory spring heats up and expands, preventing the slide blocks from approaching each other. At the same time, the controller transmits current to the electromagnet, changing the polarity of the electromagnet, so that the electromagnet and the near end of the slide block have opposite polarities, thereby pulling the slide block closer to the electromagnet, and jointly providing a rightward pulling force to the slide block to prevent the slide block from moving left, resetting the slide block, and jointly preventing the slide block from continuing to move to the left, thereby avoiding greater shaking of the mounting frame.

[0015] When the arc plate is shaken many times in the inner tank, it rubs against the inner wall of the inner tank, causing the internal temperature to rise. When the temperature exceeds the set value, it means that the temperature inside the tank is too high, causing the pressure to increase. At this time, the high temperature expands and bends the bimetallic strip, thereby pushing the push plate to compress the telescopic spring under the transmission action of the arc rod, so that electrode piece one contacts electrode piece two. The current transmitted by the controller to electrode piece one is transmitted to the pressure relief valve through electrode piece two, controlling the opening of the pressure relief valve to relieve the pressure inside the tank, thereby avoiding damage or even explosion of the explosion-proof tank due to excessive pressure, which would cause serious harm to the surrounding environment and personnel.

[0016] Furthermore, the two magnetic poles near the ends of the magnets on both sides of the mounting frame are opposite.

[0017] In order to make the arc plate move, the controller controls the electromagnets and memory springs on the left and right sides to make corresponding actions according to the different current directions in the small coil, and jointly prevent the movement of the arc plate to avoid large vibrations, deformation of the explosion-proof tank and increase in pressure caused by the large amount of heat generated by friction, thereby avoiding safety accidents.

[0018] Furthermore, the sliding block is made of a magnetic block.

[0019] In order to prevent the sliding of the slider caused by the shaking of the arc plate when the electromagnet changes its polarity, the arc plate can be prevented from shaking too much, thereby avoiding damage to the explosion-proof tank caused by the large shaking.

[0020] Furthermore, the end of the containing box away from the slide board is a hard plate, and the end close to the slide board is a soft film.

[0021] When the moving distance of the moving block does not exceed the preset value, the magnetorheological fluid is in a low viscosity state in the containing box, which plays a buffering role for the leftward movement of the slide plate and can prevent the arc plate from shaking. When the moving distance of the moving block exceeds the preset value, the large amount of magnetorheological fluid transported by the controller to the containing box becomes high viscosity. Due to the increase in the volume of the magnetorheological fluid, it will expand and deform to the right, giving the slide plate a rightward thrust, further preventing the arc plate from shaking more severely, avoiding the damage to the explosion-proof tank caused by large shaking amplitude, and also avoiding the friction between the inner tank and the large amount of heat generated due to excessive shaking amplitude, causing a sudden increase in pressure.

[0022] Furthermore, the expansion coefficient of the metal sheet at one end of the bimetallic strip close to the horizontal base is higher than that of the metal sheet at one end far from the horizontal base.

[0023] In order to make the metal plate with a high expansion coefficient deform more when the temperature reaches a certain level, the upper metal sheet is pulled downward to bend with a larger bending amplitude, so that the arc rod pushes the electrode sheet one and the electrode sheet two to contact the circuit to control the pressure relief valve to open for pressure relief.

[0024] Furthermore, the controller is electrically connected to the small coil, the controller is electrically connected to the large coil, the controller is electrically connected to the circulation pump, the controller is electrically connected to the memory spring, the controller is electrically connected to the displacement sensor, and the controller is electrically connected to electrode sheet one.

[0025] In order to realize the automation and timely response of the device, the device can respond automatically and quickly. When the temperature exceeds the set value, the pressure relief valve is opened to release the pressure in time. At the same time, when the moving block exceeds the set moving distance, the anti-shake units on the left and right sides will make corresponding actions to suppress the movement of the arc plate in time to avoid large-scale shaking and damage to the explosion-proof tank.

[0026] Compared with the prior art, the present invention has the following beneficial effects: 1. When the arc plate moves to the left, the present invention generates a reverse current by moving the magnet in the anti-shake unit inside the small coil. The controller changes the polarity of the electromagnet so that the electromagnet and the slider near the end have the same polarity, thereby pushing the slider away from the electromagnet, and jointly resisting the leftward movement of the slide plate under the action of the restoring force of the memory spring, so that the slide plate is reset. At the same time, the controller controls the circulation pump to deliver the volume of magnetorheological fluid to the containing box, and at the same time, the controller delivers current to the large coil, thereby generating a strong magnetic field, and changing the magnetorheological fluid in the containing box from low viscosity to high viscosity, thereby preventing the slide plate from continuing to move to the left, and facilitating the mounting frame to generate greater shaking. At the same time, when the right magnet moves inside the small coil, a positive current is generated. After receiving the current from the controller, the memory spring generates heat and expands, preventing the slide plates from approaching each other, and at the same time changing the polarity of the electromagnet so that the electromagnet and the slider near the end have opposite polarity, thereby pulling the slide plate close to the electromagnet, and jointly providing a rightward pulling force to the slide plate to prevent the slide plate from moving to the left, so that the slide plate is reset, and jointly preventing the slide plate from continuing to move to the left, thereby avoiding greater shaking of the mounting frame.

[0027] 2. The present invention cooperates with the magnetorheological fluid in the soft film of the containing box in the anti-shake unit. When the volume of the magnetorheological fluid increases, it will expand and deform to the right, giving the slide a rightward thrust, further preventing the arc plate from shaking more violently, avoiding damage to the explosion-proof tank caused by large shaking amplitude, and also avoiding excessive shaking amplitude and friction with the inner tank to generate a large amount of heat, causing a sudden increase in pressure.

[0031] Example: Figure 1-Figure 8 As shown, the present invention provides a technical solution: like Figure 1 , 2As shown, an isolation explosion-proof tank for engine transportation includes a tank body 1, a storage unit 2, an anti-shake unit 3 and a controller 4. The tank body 1 includes a bracket 11, an inner tank 12 and an outer tank 13. The bracket 11 is placed on a horizontal basis, the bracket 11 is fixedly connected to the outer tank 13, the inner tank 12 is installed inside the outer tank 13, the inner tank 12 is provided with a vent connected to the outer tank 13, the outer surface of the outer tank 13 is provided with a pressure relief valve, the anti-shake unit 3 is installed inside the outer tank 13, the storage unit 2 is slidably installed inside the inner tank 12, the anti-shake unit 3 is slidably connected to the storage unit 2, the anti-shake unit 3 has the function of reducing the vibration of the storage unit 2 and actively relieving the pressure of the tank body 1, the controller 4 is fixedly installed on the outer tank 13, and the controller 4 is electrically connected to the anti-shake unit 3.

[0032] The tank body 1 is used to install the anti-shake unit 3 and the storage unit 2. The storage unit 2 is used to hold the engine. The anti-shake unit 3 is used to prevent the storage unit 2 from shaking to protect the engine while actively releasing the pressure inside the tank body 1. The controller 4 controls the opening and closing of the anti-shake unit 3. When the transport vehicle passes through a rugged road when transporting the engine, causing the storage unit 2 to shake greatly inside the tank body, the anti-shake unit 3 reduces the shaking of the storage unit 2. At the same time, it also reduces the excessive pressure caused by the increase in internal temperature due to the friction between the shaking of the storage unit 2 and the inner wall of the tank body 1. When the internal temperature generated by friction is too high, the anti-shake unit 3 will release the pressure to prevent the tank from exploding due to excessive pressure.

[0033] like Figure 2 , 7 As shown, the storage unit 2 includes a mounting frame 21, a storage cylinder 22, a support plate 23 and an arc plate 24. The mounting frame 21 is fixedly connected to the arc plate 24, the storage cylinder 22 is fixedly connected to the mounting frame 21, one end of the support plate 23 is fixedly connected to the mounting frame 21, and the other end is fixedly connected to the storage cylinder 22. Circular holes are provided on the two support plates 23 away from the horizontal base, and the support plate 23 is slidably connected to the anti-shake unit 3.

[0034] When the engine needs to be transported, the staff puts the engine into the storage tube 22, and after sealing, places the mounting bracket 21 along the arc plate 24 into the inner tank 12, passes the support plate 23 through the slide rod 31, and fixes the mounting bracket 21 inside the inner tank 12 through the clamping block 35 to ensure that the engine is stable in the tank body 1 during transportation and reduce shaking.

[0035] like Figure 3 , 4As shown in Figures 5, 6 and 8, the anti-shake unit 3 includes a slide bar 31, a slide plate 32, a moving block 33, a magnet 34, a clamping block 35, a small coil 36, a large coil 37, a slide block 38, a guide rod 39, an electromagnet 310, a rocker rod 311, a memory spring 312, a circulating pump 313, a containing box 314, a displacement sensor 315, a bimetallic strip 316, an arc rod 317, an electrode sheet 1 318, an electrode sheet 2 319, a telescopic spring 320 and a push plate 321. The slide bar 31 is slidably connected to the support plate 23, both ends of the slide bar 31 are fixedly connected to the pipe cover of the outer tank 13, and the slide plate 32 is slidably mounted on the slide bar 31 The slide plate 32 is installed inside the inner tank 12, the moving block 33 is fixedly installed on the side of the slide plate 32 close to the storage unit 2, one end of the magnet 34 is fixedly connected to the moving block 33, and the other end is fixedly connected to the clamping block 35, there are two clamping blocks 35, and the two clamping blocks 35 are clamped with the mounting frame 21, the small coil 36 is evenly wound on the outer surface of the slide bar 31, and the large coil 37 is evenly wound on the outer surface of the inner tank 12. A rectangular groove is opened at one end of the slide plate 32 away from the mounting frame 21, and the electromagnet 310 is fixedly installed at both ends of the rectangular groove of the slide plate 32, and both ends of the guide rod 39 are fixedly connected to the electromagnet 310, and the slider 38 is slidably installed on the guide rod 39. On the rod 39, one end of the swing rod 311 is rotatably connected to the slider 38, and the other end is rotatably connected to the end of the storage box 314 close to the slide 32. The two ends of the memory spring 312 are respectively fixedly connected to the two swing rods 311. The circulation pump 313 is fixedly installed on the end surface of the outer tank 13 away from the horizontal foundation. The circulation pump 313 is connected to the storage box 314 through a pipeline. The storage box 314 is fixedly installed at both ends inside the outer tank 13. The storage box 314 is fixedly connected to the slide bar 31 at one end away from the slide 32. The storage box 314 is used to hold the magnetorheological fluid. The end close to the slide 32 is slidably connected to the slide bar 31. The displacement sensor 315 is fixed It is installed on the inner wall of the outer tank 13 away from the horizontal foundation. One end of the bimetallic strip 316 is fixedly installed on the end of the slide plate 32 close to the mounting frame 21, and the other end is fixedly connected to the push plate 321 through the arc rod 317 close to the horizontal foundation. A circular groove is opened at the end of the slide plate 32 close to the mounting frame 21, and the push plate 321 is slidably installed in the circular groove opened on the slide plate 32. Electrode sheet 1 318 is fixedly installed on the end of the push plate 321 close to the containing box 314, and electrode sheet 2 319 is fixedly installed inside the circular groove of the slide plate 32. One end of the telescopic spring 320 is fixedly connected to electrode sheet 2 319, and the other end is fixedly connected to the push plate 321.

[0036] When the transport vehicle passes through complex road conditions or the vehicle accelerates, decelerates, and turns, causing the storage unit 2 to shake left and right in the inner tank 12, the arc plate 24 moves to the left, pushing the clamping block 35 on the left to drive the magnet 34 and the moving block 33 to move to the left, thereby pushing the slide plate 32 to move to the left along the slide rod 31, thereby squeezing the rocker rod 311 to push the slider 38 away from each other along the guide rod 39 while stretching the memory spring 312. On the one hand, when the magnet 34 moves inside the small coil 36, the magnetic flux changes, thereby generating a reverse current in the small coil 36. The small coil 36 transmits the current signal to the controller 4. According to the direction of the electrical signal, the controller 4 does not supply current to the memory spring 312, but supplies current to the electromagnet 310, thereby changing the polarity of the electromagnet 310 and bringing the electromagnet 310 closer to the slider 38. The two ends have the same polarity, thereby pushing the slider 38 away from the electromagnet 310, and under the action of the restoring force of the memory spring 312, they jointly resist the leftward movement of the slider 32, so that the slider 32 is reset, and the arc plate 24 is prevented from moving too much in the inner tank 12 and shaking. On the other hand, when the displacement sensor 315 detects that the moving block 33 moves to the left, it is judged as a negative value, and the signal is transmitted to the controller 4 according to the size of the moving distance. The controller 4 determines the size of the shaking of the arc plate 24 according to the distance moved by the moving block 33, thereby controlling the circulation pump 313 to transport the volume of magnetorheological fluid into the containing box 314. At the same time, the controller 4 transmits current to the large coil 37, thereby generating a strong magnetic field, and changing the magnetorheological fluid in the containing box 314 from low viscosity to high viscosity, preventing the slider 32 from continuing to move to the left, and avoiding greater shaking of the mounting frame 21.

[0037] When the arc plate 24 moves to the left, the clamping block 35 on the right is pulled to drive the magnet 34 and the moving block 33 to move to the left, thereby pulling the right slide plate 32 to move to the left along the slide rod 31, thereby driving the two slide blocks 38 to approach each other along the guide rod 39 while compressing the memory spring 312. On the one hand, when the magnet 34 on the right moves inside the small coil 36, the magnetic flux changes synchronously, thereby generating a positive current in the small coil 36. The small coil 36 transmits the current signal to the controller 4, and the controller 4 is positive according to the direction of the electrical signal. When current is supplied, current is supplied to memory spring 312, which heats up and expands after receiving the current, thereby preventing sliders 38 from approaching each other. At the same time, controller 4 supplies current to electromagnet 310, thereby changing the polarity of electromagnet 310, so that electromagnet 310 and the slider 38 near the end have opposite polarities, thereby pulling slider 38 close to electromagnet 310, and jointly providing a rightward pulling force to slider 32 to prevent slider 32 from moving left, thereby resetting slider 32, and jointly preventing slider 32 from continuing to move left, thereby avoiding greater shaking of mounting frame 21.

[0038] When the arc plate 24 is shaken multiple times in the inner tank 12, it rubs against the inner wall of the inner tank 12, causing the internal temperature to rise. When the temperature exceeds the set value, it means that the temperature inside the tank body 1 is too high, causing the pressure to increase. At this time, the high temperature expands and bends the bimetallic strip 316, thereby pushing the push plate 321 to compress the telescopic spring 320 under the transmission action of the arc rod 317, so that the electrode piece 1 318 is in contact with the electrode piece 2 319. The current transmitted by the controller 4 to the electrode piece 1 318 is transmitted to the pressure relief valve through the electrode piece 2 319, controlling the pressure relief valve to open and relieving the pressure inside the tank body 1 to avoid damage or even explosion of the explosion-proof tank due to excessive pressure, causing serious harm to the surrounding environment and personnel.

[0039] like Figure 5 As shown, the two magnetic poles near the ends of the magnets 34 on both sides of the mounting frame 21 are opposite.

[0040] In order to make the arc plate 24 move, the controller 4 controls the electromagnets 310 and the memory springs 312 on the left and right sides to make corresponding actions according to the different current directions in the small coil 36, so as to jointly prevent the movement of the arc plate 24 and avoid large vibrations, which may cause deformation of the explosion-proof tank and increase of pressure caused by a large amount of heat generated by friction, thereby avoiding safety accidents.

[0041] like Figure 6 As shown, the slider 38 is made of a magnetic block.

[0042] In order to prevent the sliding of the slider 38 caused by the shaking of the arc plate 24 when the electromagnet 310 changes its polarity, the arc plate 24 is prevented from shaking greatly, thereby avoiding damage to the explosion-proof tank caused by the large shaking.

[0043] like Figure 5 As shown, the end of the containing box 314 away from the slide plate 32 is a hard plate, and the end close to the slide plate 32 is a soft film.

[0044] When the moving distance of the moving block 33 does not exceed the preset value, the magnetorheological fluid is in a low viscosity state in the containing box 314, which plays a buffering role for the leftward movement of the slide plate 32, and can prevent the arc plate 24 from shaking. When the moving distance of the moving block 33 exceeds the preset value, the large amount of magnetorheological fluid transported by the controller 4 to the containing box 314 becomes high viscosity. Due to the increase in the volume of the magnetorheological fluid, it will expand and deform to the right, giving the slide plate 32 a rightward thrust, further preventing the arc plate 24 from shaking more, avoiding the large shaking amplitude causing damage to the explosion-proof tank, and also avoiding the excessive shaking amplitude causing friction with the inner tank 12 to generate a large amount of heat, causing a sudden increase in pressure.

[0045] like Figure 8 As shown, the expansion coefficient of the metal sheet at one end of the bimetallic strip 316 close to the horizontal base is higher than that of the metal sheet at one end away from the horizontal base.

[0046] In order to make the metal plate with a high expansion coefficient deform more when the temperature reaches a certain level, thereby pulling the upper metal sheet to bend downward and generating a larger bending amplitude, the arc rod 317 pushes the electrode sheet 1 318 and the electrode sheet 2 319 to contact the conduction circuit, thereby controlling the pressure relief valve to open for pressure relief.

[0047] like Figure 1 As shown, the controller 4 is electrically connected to the small coil 36, the controller 4 is electrically connected to the large coil 37, the controller 4 is electrically connected to the circulation pump 313, the controller 4 is electrically connected to the memory spring 312, the controller 4 is electrically connected to the displacement sensor 315, and the controller 4 is electrically connected to the electrode sheet 1 318.

[0048] In order to realize the automation and timely response of the device, the device can be made to respond automatically and quickly. When the temperature exceeds the set value, the pressure relief valve is opened to release the pressure in time. At the same time, when the moving block 33 exceeds the set moving distance, the anti-shake units 3 on the left and right sides promptly make corresponding actions to suppress the movement of the arc plate 24 to avoid large-scale shaking that causes damage to the explosion-proof tank.

[0049] Working principle of the present invention: When the engine needs to be transported, the staff puts the engine into the storage tube 22, and after sealing, places the mounting bracket 21 along the arc plate 24 into the inner tank 12, passes the support plate 23 through the slide rod 31, and fixes the mounting bracket 21 inside the inner tank 12 through the clamping block 35 to ensure that the engine is stable in the tank body 1 during transportation and reduce shaking.

[0050] When the transport vehicle passes through complex road conditions or the vehicle accelerates, decelerates, and turns, causing the storage unit 2 to shake left and right in the inner tank 12, the arc plate 24 moves to the left, pushing the clamping block 35 on the left to drive the magnet 34 and the moving block 33 to move to the left, thereby pushing the slide plate 32 to move to the left along the slide rod 31, thereby squeezing the rocker rod 311 to push the slider 38 away from each other along the guide rod 39 while stretching the memory spring 312. On the one hand, when the magnet 34 moves inside the small coil 36, the magnetic flux changes, thereby generating a reverse current in the small coil 36. The small coil 36 transmits the current signal to the controller 4. According to the direction of the electrical signal, the controller 4 does not supply current to the memory spring 312, but supplies current to the electromagnet 310, thereby changing the polarity of the electromagnet 310 and bringing the electromagnet 310 closer to the slider 38. The two ends have the same polarity, thereby pushing the slider 38 away from the electromagnet 310, and under the action of the restoring force of the memory spring 312, they jointly resist the leftward movement of the slider 32, so that the slider 32 is reset, and the arc plate 24 is prevented from moving too much in the inner tank 12 and shaking. On the other hand, when the displacement sensor 315 detects that the moving block 33 moves to the left, it is judged as a negative value, and the signal is transmitted to the controller 4 according to the size of the moving distance. The controller 4 determines the size of the shaking of the arc plate 24 according to the distance moved by the moving block 33, thereby controlling the circulation pump 313 to transport the volume of magnetorheological fluid into the containing box 314. At the same time, the controller 4 transmits current to the large coil 37, thereby generating a strong magnetic field, and changing the magnetorheological fluid in the containing box 314 from low viscosity to high viscosity, preventing the slider 32 from continuing to move to the left, and avoiding greater shaking of the mounting frame 21.

[0051] When the arc plate 24 moves to the left, the clamping block 35 on the right is pulled to drive the magnet 34 and the moving block 33 to move to the left, thereby pulling the right slide plate 32 to move to the left along the slide rod 31, thereby driving the two slide blocks 38 to approach each other along the guide rod 39 while compressing the memory spring 312. On the one hand, when the magnet 34 on the right moves inside the small coil 36, the magnetic flux changes synchronously, thereby generating a positive current in the small coil 36. The small coil 36 transmits the current signal to the controller 4, and the controller 4 is positive according to the direction of the electrical signal. When current is supplied, current is supplied to memory spring 312, which heats up and expands after receiving the current, thereby preventing sliders 38 from approaching each other. At the same time, controller 4 supplies current to electromagnet 310, thereby changing the polarity of electromagnet 310, so that electromagnet 310 and the slider 38 near the end have opposite polarities, thereby pulling slider 38 close to electromagnet 310, and jointly providing a rightward pulling force to slider 32 to prevent slider 32 from moving left, thereby resetting slider 32, and jointly preventing slider 32 from continuing to move left, thereby avoiding greater shaking of mounting frame 21.

[0052] When the arc plate 24 is shaken multiple times in the inner tank 12, it rubs against the inner wall of the inner tank 12, causing the internal temperature to rise. When the temperature exceeds the set value, it means that the temperature inside the tank body 1 is too high, causing the pressure to increase. At this time, the high temperature expands and bends the bimetallic strip 316, thereby pushing the push plate 321 to compress the telescopic spring 320 under the transmission action of the arc rod 317, so that the electrode piece 1 318 is in contact with the electrode piece 2 319. The current transmitted by the controller 4 to the electrode piece 1 318 is transmitted to the pressure relief valve through the electrode piece 2 319, controlling the pressure relief valve to open and relieving the pressure inside the tank body 1 to avoid damage or even explosion of the explosion-proof tank due to excessive pressure, causing serious harm to the surrounding environment and personnel.
