Description

Technical Field

[0001] This application relates to the field of safety protection technology for the storage and transportation of hazardous chemicals, and in particular to emergency isolation and protection equipment for hazardous sources in the sealed environment of shipping holds. Background Technology

[0002] With the rapid development of the chemical and energy industries, the production, storage, and transportation of hazardous chemicals are constantly expanding. These substances often need to be transferred and handled in sealed containers or enclosed spaces. In shipping scenarios, ship holds, as special sealed environments with relatively limited space and ventilation, often employ centralized storage and zoned stacking for the management of corrosive and highly hazardous chemicals.

[0003] In related technologies, the aforementioned methods for protecting and monitoring sealed environments rely on leak sensors to detect abnormal leaks of hazardous chemicals and trigger audible and visual alarm devices when a leak is detected, so as to alert on-site personnel to take appropriate measures.

[0004] However, the above methods can only achieve passive early warning of leaks. When a hazardous chemical leak occurs in a storage unit, it is impossible to isolate and contain the leak source spatially. The leaked medium can cause corrosion and erosion to surrounding hazardous chemical containers, cabin structures and other materials that have not leaked, which can easily lead to safety accidents and create safety hazards. Summary of the Invention

[0005] Therefore, it is necessary to provide an emergency isolation and protection device for hazardous sources in the sealed environment of shipping holds, which addresses the current problem of the inability to actively seal and isolate hazardous chemical leaks in the current enclosed space of ship holds, thus causing safety hazards.

[0006] According to one aspect of this application, an emergency isolation and protection device for hazardous sources in a sealed environment of a shipping vessel is provided, comprising: a fixed plate; two limiting plates symmetrically disposed on both sides of the fixed plate; a movable base movably disposed between the two limiting plates; a sealing groove disposed on the upper end of the movable base; a fixed frame disposed on the upper end of the fixed plate; a sealing explosion-proof cover detachably disposed on the fixed frame; a mounting plate disposed inside the sealing explosion-proof cover; an absorbent disposed inside the sealing explosion-proof cover above the mounting plate; a plurality of dispensing holes arranged in a circumferential array at the lower end of the mounting plate; a baffle plate rotatably disposed within the dispensing holes via a hinge; a triggering component disposed on one side of the baffle plate and connected to the baffle plate; and a leak detector disposed on one side of the fixed frame.

[0009] In one embodiment, a guide block is provided at the upper end of the mounting plate, and the guide block is conical.

[0010] In one embodiment, the triggering component includes an electromagnetic lock, a ranging sensor, and a first controller; the electromagnetic lock is located at the lower end of the mounting plate on one side of the baffle plate; the first controller is located inside the guide block; and the ranging sensor is located at the lower end of the mounting plate between the multiple electromagnetic locks.

[0011] In one embodiment, a first guide rod is provided on both sides of the surface of the sealed explosion-proof cover, a first guide ring is sleeved on the first guide rod, a movable block is provided on the first guide ring, and a sliding groove is provided through the lower end of the movable block; a second guide rod is provided on the upper end of the movable base on both sides of the sealing groove, a second guide ring is movably sleeved on the second guide rod, and a sliding plate is provided on the upper end of the second guide ring, and the sliding plate is slidably disposed in the corresponding sliding groove.

[0012] In one embodiment, a sealing gasket is provided in the sealing groove, and the sealing gasket is made of fluororubber material.

[0013] In one embodiment, the system further includes a pressure plate, a second electric push rod, a second connecting plate, a pressure sensor, a guide rod, and a second controller. A support base is located at the upper end of the movable base, and a drive motor is located within the support base. A connecting shaft is located at the output end of the drive motor, and a rotating plate is located at the upper end of the connecting shaft. A second electric push rod is located at the upper end of the rotating plate, and a second connecting plate is located at the output end of the second electric push rod. A pressure sensor is located at the lower center of the second connecting plate. Through holes are formed on both sides of the pressure sensor on the second connecting plate, and guide rods pass through these through holes. The upper end of the guide rod is movably engaged with the second connecting plate, and the lower end of the guide rod is fixedly connected to the pressure plate. A second controller is located on one side of the support base.

[0014] In one embodiment, the connecting shaft is arranged in a vertical direction, and the rotating plate is arranged perpendicular to the connecting shaft.

[0015] In one embodiment, the first end of the limiting block is disposed in the rotating groove via a rotating shaft, and the second end of the limiting block abuts against one side of the movable base when the limiting block is rotated to a vertical position; the movable baffle is located directly above the limiting block, and the two sides of the movable baffle slide in cooperation with the guide plate.

[0016] The aforementioned emergency isolation and protection equipment for hazardous sources in the sealed environment of shipping holds features a leak detector that detects a leak of hazardous substances. When the leak detector detects a leak, the sealing explosion-proof cover falls and cooperates with the sealing groove to form a closed isolation space. At the same time, the trigger component drives the baffle plate to open, and the adsorbent is evenly distributed through the dispensing hole to adsorb the harmful substances. This achieves rapid spatial isolation and active adsorption treatment of the leak source, shortens the delay in emergency response, and improves safety. Attached Figure Description

[0030] See Figure 1 , Figure 1 This is a schematic diagram of the structure of an emergency isolation and protection device according to some embodiments of this application.

[0031] An embodiment of this application provides an emergency isolation and protection device for hazardous sources in a sealed environment of a shipping ship's hold, including a fixed plate 1, two limiting plates 2, a movable base 3, a sealing groove 5, a fixing frame 6, a sealing explosion-proof cover 7, a mounting plate 8, an absorbent 9, multiple discharge holes 10, a baffle plate 11, a triggering component, and a leak detector 35.

[0032] The fixed plate 1 serves as a supporting component for the overall equipment. Two limiting plates 2 are symmetrically arranged on both sides of the fixed plate 1. The limiting plates 2 provide a regular movement track for the movable base 3, restrict its movement direction, prevent the movable base 3 from deviating during movement, and ensure the accuracy of equipment operation.

[0033] The movable base 3 is movably positioned between the two limiting plates 2. The movable base 3 can move under the guidance of the limiting plates 2 and is used to support containers containing hazardous chemicals. When necessary, it can quickly transfer the hazardous source of the leak seal to avoid affecting other sealed chemical hazardous sources.

[0034] The sealing groove 5 is located on the upper end of the movable base 3. The sealing groove 5 is an upward-opening groove structure, which is used to cooperate with the sealing explosion-proof cover 7. After the sealing explosion-proof cover 7 is in place, it forms a closed sealing space for the leaking hazard source, preventing the hazardous substances from spreading outward.

[0035] The fixing bracket 6 is located on the upper end of the fixing plate 1 and extends upward to provide support and installation foundation for the sealed explosion-proof cover 7.

[0036] The sealed explosion-proof cover 7 is detachably mounted on the fixed frame 6. The sealed explosion-proof cover 7 is a hollow cover structure that can fall to the position of the sealing groove 5 under the control of the drive component, and cooperate with the sealing groove 5 to form a closed space, thereby effectively isolating the leaking hazard source from the external environment, and preventing dangerous situations such as explosions from affecting the external environment.

[0037] The mounting plate 8 is located inside the sealed explosion-proof cover 7, and the mounting plate 8 divides the inside of the sealed explosion-proof cover 7 into upper and lower spatial areas.

[0038] The adsorbent 9 is placed in the sealed explosion-proof cover 7 above the mounting plate 8. The adsorbent 9 is a granular or powdered adsorbent material that can adsorb harmful substances when a leak occurs, thereby reducing the concentration and severity of the hazardous substances.

[0039] Multiple dispensing holes 10 are arranged in a circular array at the lower end of the mounting plate 8. The circular array of dispensing holes 10 enables the adsorbent 9 to be evenly distributed into the sealed environment under the action of gravity, thereby improving the adsorption effect and ensuring effective control of hazardous sources.

[0040] The baffle plate 11 is rotatably mounted in the dispensing hole 10 via a hinge. In the initial state, the baffle plate 11 closes the dispensing hole 10, keeping the adsorbent 9 in the space above the mounting plate 8; when dispensing is required, the baffle plate 11 rotates downward around the hinge under the action of the triggering component, opening the dispensing hole 10, allowing the adsorbent 9 to fall into the sealed environment through the dispensing hole 10.

[0041] The triggering component is located on one side of the baffle plate 11 and connected to the baffle plate 11. After receiving the control signal, the triggering component is activated to drive the baffle plate 11 to open or close, thereby realizing the automatic spreading control of the adsorbent 9.

[0042] Leak detector 35 is mounted on one side of the mounting bracket 6. Leak detector 35 is used to detect the leakage of hazardous substances in a sealed environment in real time. When a leakage signal is detected, it sends a trigger signal to the control system to activate the emergency protection procedure.

[0043] In this embodiment, under normal operating conditions, the sealed explosion-proof cover 7 is held in a raised position above the movable base 3 by the fixing bracket 6. Containers containing hazardous chemicals can be placed on the movable base 3. The leak detector 35 continuously monitors the sealed environment. When the leak detector 35 detects a hazardous substance leak, it activates the emergency protection control program. The sealed explosion-proof cover 7 is released and falls vertically. The lower opening of the sealed explosion-proof cover 7 mates with the sealing groove 5 at the upper end of the movable base 3, sealing the leak source within the sealed space formed by the sealed explosion-proof cover 7 and the sealing groove 5. Simultaneously, the triggering component activates, driving the baffle plate 11 inside the dispensing hole 10 to open. The adsorbent 9 is evenly distributed from above the mounting plate 8 through the dispensing hole 10 into the sealed space, adsorbing the leaked hazardous substance. This achieves rapid spatial isolation and active adsorption treatment of the leaking hazardous source, shortening the time delay from the occurrence of the leak to emergency response.

[0044] like Figure 2 and Figure 6 As shown, Figure 2 This is a front cross-sectional view of an emergency isolation and protection device according to some embodiments of this application. Figure 6 This is a cross-sectional schematic diagram of the limiting plate 2 according to some embodiments of this application. In one embodiment, it also includes a limiting block 401, a movable baffle 402, and a guide plate 403.

[0045] The limiting plate 2 is Z-shaped. The two ends of the movable base 3 are in contact with the surface of the limiting plate 2, and the movable base 3 slides along the extension direction of the limiting plate 2. The Z-shaped limiting plate 2 structure provides a stable support surface for the movable base 3, while also limiting the lateral freedom of the movable base 3.

[0046] A rotating groove 14 is provided through the upper end of the limiting plate 2. A limiting block 401, which is fan-shaped, is rotatably mounted in the rotating groove 14 via a rotating shaft. The rotating groove 14 is a through groove that passes vertically through the upper end of the limiting plate 2. The rotating shaft is horizontally positioned in the rotating groove 14, and the limiting block 401 is fitted onto the rotating shaft through a mounting hole at one end. The fan-shaped limiting block 401 can rotate around the rotating shaft in the rotating groove 14. When the limiting block 401 rotates to the vertical position, the outer arc-shaped surface of the limiting block 401 extends outward and is located on one side of the movable base 3, thus blocking and limiting the movable base 3.

[0047] A guide plate 403 is provided on the upper end of the limiting plates 2 on both sides of the rotating groove 14, and a movable baffle 402 is slidably arranged between the two guide plates 403. The two guide plates 403 are arranged parallel in the vertical direction to form a guide slide. The two sides of the movable baffle 402 are inserted into the guide slide of the guide plate 403 and can slide up and down along the guide plate 403. When the movable baffle 402 moves down to contact the top of the limiting block 401, the movable baffle 402 limits the limiting block 401, preventing the limiting block 401 from rotating around the axis, thereby maintaining the limiting block 401 blocking the movable base 3.

[0048] The rotation of the sector-shaped limit block 401 is used to block and release the movable base 3. Combined with the movable baffle 402 locking the rotational freedom of the limit block 401, the movement stroke of the movable base 3 is precisely controlled, avoiding accidental movement of the movable base 3 and improving the safety and stability of the equipment operation.

[0049] like Figure 2 As shown, Figure 2 This is a front cross-sectional view of an emergency isolation and protection device according to some embodiments of this application. In one embodiment, the upper end of the fixing frame 6 is provided with a first electric push rod 15, the output end of the first electric push rod 15 is provided with a first connecting plate 16, the lower end of the first connecting plate 16 is provided with an electromagnet 17, and the sealed explosion-proof cover 7 is adsorbed and disposed at the lower end of the electromagnet 17.

[0050] The first electric push rod 15 is fixedly mounted on the upper surface of the fixing frame 6, and its output end extends downward through the fixing frame 6 to the bottom of the fixing frame 6. The first connecting plate 16 is fixedly connected to the lower end of the output end of the first electric push rod 15. The electromagnet 17 is fixedly mounted on the lower surface of the first connecting plate 16. The top of the sealed explosion-proof cover 7 is made of ferromagnetic material and is attracted and fixed to the lower end of the electromagnet 17 when the electromagnet 17 is energized.

[0051] In the initial state, the electromagnet 17 is energized, generating a magnetic attraction that draws the sealed explosion-proof cover 7 to its lower end. The first electric push rod 15 retracts, raising the sealed explosion-proof cover 7 to the raised position below the fixed frame 6, providing sufficient space for the movement of the movable base 3 and the placement of the hazardous source container. When the leak detector 35 detects a hazardous substance leak, the electromagnet 17 is de-energized, the magnetic attraction disappears, and the sealed explosion-proof cover 7 falls freely vertically under gravity, landing in the sealing groove 5 on the movable base 3, forming a sealed space with the sealing groove 5. By controlling the on / off state of the electromagnet 17, the rapid release and automatic control of the falling of the sealed explosion-proof cover 7 are achieved, ensuring the timeliness and reliability of emergency response.

[0052] like Figure 2 , Figure 3As shown, in one embodiment, the upper end of the mounting plate 8 is provided with a guide block 18, which is conical. The upper end of the guide block 18 is a cone tip, and the lower end is a cone base, and it is fixedly disposed in the middle of the upper end surface of the mounting plate 8.

[0053] When the adsorbent 9 fills the space inside the sealed explosion-proof cover 7 above the mounting plate 8, the adsorbent 9 particles or powder accumulate around the guide block 18. The conical slope of the guide block 18 acts as a diversion and guidance mechanism: when the adsorbent 9 falls from above, the conical slope evenly disperses the adsorbent 9 in all directions, allowing it to be evenly distributed along the conical slope to the upper area of ​​the mounting plate 8. When the adsorbent 9 distributed to the area is subsequently spread downwards through the dispensing hole 10 at the lower end of the mounting plate 8, the discharge from the dispensing hole 10 is more uniform because the distribution of the adsorbent 9 on the mounting plate 8 has been homogenized by the conical guide block 18. This results in a more uniform dispensing effect of the adsorbent 9 within the sealed space, improving the overall adsorption efficiency of the adsorbent 9 for harmful substances.

[0054] like Figure 3 As shown, Figure 3 This is a bottom view of a sealed explosion-proof cover 7 according to some embodiments of this application. In one embodiment, the triggering components include an electromagnetic lock 1201, a ranging sensor 1202, and a first controller 1203.

[0055] An electromagnetic lock 1201 is provided at the lower end of the mounting plate 8 on one side of the baffle plate 11. Each material discharge hole 10 is provided with a corresponding electromagnetic lock 1201. The electromagnetic lock 1201 is located on one side of the baffle plate 11. When locked, its locking tongue is inserted into the limiting hole of the baffle plate 11 to prevent the baffle plate 11 from rotating around the hinge to open. When unlocked, the locking tongue retracts, releasing the baffle plate 11 so that the baffle plate 11 can rotate freely to open.

[0056] The first controller 1203 is located inside the guide block 18. The guide block 18 has a cavity, and the first controller 1203 is located inside the cavity and is electrically connected to the electromagnetic lock 1201 and the ranging sensor 1202 via wires.

[0057] A distance sensor 1202 is located at the lower end of a mounting plate 8 between multiple electromagnetic locks 1201. The distance sensor 1202 has a vertical downward detection direction and is used to detect the vertical distance between the lower surface of the mounting plate 8 and the sealed hazard source.

[0058] During emergency protection, after the sealed explosion-proof cover 7 falls to the position of the sealing groove 5, the distance sensor 1202 detects the distance between the mounting plate 8 and the sealed hazard source in real time. When the distance is less than a preset threshold parameter, the distance sensor 1202 sends a signal to the first controller 1203. The first controller 1203 sends an unlocking command to the electromagnetic lock 1201 according to the preset program. The latch of the electromagnetic lock 1201 retracts, and the baffle plate 11 opens downward under the pressure of the adsorbent 9. The adsorbent 9 is evenly distributed into the sealed environment through the dispensing hole 10. Through the cooperation of the distance sensor 1202 and the first controller 1203, the timing of the opening of the baffle plate 11 is precisely and automatically controlled, ensuring that the adsorbent 9 is distributed only after the sealed explosion-proof cover 7 is in place, avoiding a decrease in adsorption effect caused by dispensing too early or too late.

[0059] like Figure 4 As shown, Figure 4 According to some embodiments of this application Figure 1 Enlarged view of point A. In one embodiment, the sealed explosion-proof cover 7 has first guide rods 19 on both sides of its surface, a first guide ring 20 is sleeved on the first guide rods 19, a moving block 21 is provided on the first guide ring 20, and a sliding groove 22 is provided through the lower end of the moving block 21.

[0060] For example, the first guide rod 19 is fixedly disposed vertically on both sides of the outer surface of the sealed explosion-proof cover 7. The first guide ring 20 is movably sleeved on the first guide rod 19 and can slide up and down along the first guide rod 19. The moving block 21 is fixedly disposed on the outer surface of the first guide ring 20 and moves up and down synchronously with the first guide ring 20. The lower end of the moving block 21 has a sliding groove 22 that passes through in the horizontal direction.

[0061] The upper end of the movable base 3 on both sides of the sealing groove 5 is provided with a second guide rod 23, and a second guide ring 24 is movably sleeved on the second guide rod 23. The upper end of the second guide ring 24 is provided with a sliding plate 25, and the sliding plate 25 is slidably disposed in the corresponding sliding groove 22.

[0062] The second guide rod 23 is fixedly mounted vertically on the upper surface of the movable base 3, located on both sides of the sealing groove 5. The second guide ring 24 is movably sleeved on the second guide rod 23 and can slide up and down along the second guide rod 23. The sliding plate 25 is fixedly mounted on the upper end of the second guide ring 24, extends horizontally and inserts into the sliding groove 22 of the corresponding movable block 21, and slides in cooperation with the sliding groove 22.

[0063] When the explosion-proof sealed cover 7 falls, the first guide rod 19 moves down with the explosion-proof sealed cover 7, and the first guide ring 20 slides along the first guide rod 19. At the same time, the moving block 21, through the cooperation between the sliding groove 22 and the sliding plate 25, links the sliding state of the second guide ring 24 along the second guide rod 23 with the falling movement of the explosion-proof sealed cover 7. Through the dual guiding effect of the first guide rod 19 and the first guide ring 20, the second guide rod 23 and the second guide ring 24, and the horizontal limiting of the sliding plate 25 and the sliding groove 22, the horizontal swaying and deflection of the explosion-proof sealed cover 7 during the falling process are effectively restrained, so that the lower opening of the explosion-proof sealed cover 7 can be positioned and aligned with the sealing groove 5, ensuring a reliable connection and seal between the explosion-proof sealed cover 7 and the sealing groove 5.

[0064] In one embodiment, a sealing gasket 26 is provided in the sealing groove 5, and the sealing gasket 26 is made of fluororubber material.

[0065] The shape of the sealing gasket 26 matches the inner contour of the sealing groove 5, and it is attached to the inner wall and bottom surface of the sealing groove 5. The sealing gasket 26 is made of fluororubber material.

[0066] When the lower end of the explosion-proof cover 7 falls into the sealing groove 5, the lower edge of the explosion-proof cover 7 comes into close contact with the sealing gasket 26 and applies a certain amount of pressure. Under the pressure, the sealing gasket 26 undergoes elastic deformation, filling the gap between the explosion-proof cover 7 and the sealing groove 5, forming a reliable sealing interface.

[0067] like Figure 5 As shown, Figure 5 This is a schematic diagram of the installation of the pressure plate 13 according to some embodiments of this application. In one embodiment, it also includes the pressure plate 13, a second electric push rod 31, a second connecting plate 32, a pressure sensor 33, a guide rod 34, and a second controller 36.

[0068] The movable base 3 has a support base 27 on its upper end. The support base 27 is a hollow seat structure, fixedly mounted on the upper end face of the movable base 3, located in front of the sealed explosion-proof cover 7. The support base 27 has a drive motor 28 inside, which is fixed in the inner cavity of the support base 27, and its output shaft extends vertically upwards from the upper end of the support base 27.

[0069] The output end of the drive motor 28 is provided with a connecting shaft 29. The upper end of the connecting shaft 29 is fixedly connected to the output shaft of the drive motor 28 and rotates together with the output shaft of the drive motor 28. The upper end of the connecting shaft 29 is provided with a rotating plate 30. The rotating plate 30 is a horizontally arranged plate structure, one end of which is fixedly connected to the connecting shaft 29. Under the drive of the drive motor 28, the rotating plate 30 can rotate around the axis of the connecting shaft 29 in the horizontal plane.

[0070] The upper end of the rotating plate 30 is provided with a second electric push rod 31, which is fixedly mounted on the upper end surface of the rotating plate 30, and its extension and retraction direction is vertical. The output end of the second electric push rod 31 is provided with a second connecting plate 32, which can move up and down vertically under the drive of the second electric push rod 31.

[0071] A pressure sensor 33 is provided at the lower center of the second connecting plate 32. The pressure sensor 33 is used to detect the pressure applied to it. Through holes are provided on both sides of the second connecting plate 32. Guide rods 34 are inserted through the through holes. The upper end of the guide rods 34 passes through the through holes and extends upward beyond the upper end surface of the second connecting plate 32. The rod body of the guide rod 34 is movably fitted with the wall of the through hole, and the guide rod 34 can slide freely in the vertical direction relative to the second connecting plate 32. The lower end of the guide rod 34 is fixedly connected to the pressure plate 13. The pressure plate 13 is a horizontally set plate structure, which is suspended below the second connecting plate 32 by the two guide rods 34. The upper end surface of the pressure plate 13 is fixedly connected to the lower end of the guide rod 34.

[0072] A second controller 36 is provided on one side of the support base 27. The second controller 36 is electrically connected to the drive motor 28, the second electric push rod 31 and the pressure sensor 33, and is used to coordinate and control the timing of the operation of the electrical components.

[0073] In the initial state, the rotating plate 30 is located in front of the sealing explosion-proof cover 7, the second electric push rod 31 is in the retracted state, and the pressure plate 13 is in the raised position above the moving base 3, which does not affect the movement of the moving base 3 or the descent of the sealing explosion-proof cover 7. After the sealing explosion-proof cover 7 falls to the sealing groove 5 and completes the initial sealing, the second controller 36 starts the drive motor 28. The drive motor 28 drives the rotating plate 30 to rotate 90° around the connecting shaft 29 in the horizontal plane through the connecting shaft 29, causing the second electric push rod 31 and the pressure plate 13 to rotate as a whole to the position directly above the sealing explosion-proof cover 7. Subsequently, the second controller 36 starts the second electric push rod 31. The second electric push rod 31 extends and pushes the second connecting plate 32 to move downward. The second connecting plate 32 drives the pressure plate 13 to move downward together through the guide rod 34, so that the lower end face of the pressure plate 13 contacts the upper end face of the sealing explosion-proof cover 7 and applies downward pressure to the sealing explosion-proof cover 7.

[0074] During the downward pressing of the pressure plate 13, the sealing explosion-proof cover 7 generates an upward reaction force on the pressure plate 13. This reaction force is transmitted to the second connecting plate 32 through the guide rod 34, compressing the pressure sensor 33 located at the lower center of the second connecting plate 32. The pressure value detected by the pressure sensor 33 in real time increases with the downward movement of the pressure plate 13. When the pressure value reaches the preset sealing pressure threshold, the second controller 36 sends a stop command to the second electric push rod 31. The second electric push rod 31 stops extending and maintains its current extension amount, while the pressure plate 13 remains in its current position and continues to apply pressure to the sealing explosion-proof cover 7. Under the action of pressure, the lower edge of the sealing explosion-proof cover 7 is tightly pressed into the sealing gasket 26 in the sealing groove 5, realizing a combined seal between the sealing explosion-proof cover 7 and the sealing groove 5, further enhancing the sealing effect and ensuring the reliability of the sealing space.

[0075] In one embodiment, the connecting shaft 29 is arranged in a vertical direction, and the rotating plate 30 is arranged perpendicular to the connecting shaft 29.

[0076] The connecting shaft 29 extends vertically, with its lower end fixedly connected to the output shaft of the drive motor 28, and its upper end extending upward from the support base 27. The rotating plate 30 is a horizontally arranged plate structure, with its root fixedly connected to the upper end of the connecting shaft 29, and its surface extending perpendicularly to the axis of the connecting shaft 29. Since the connecting shaft 29 is vertically arranged, the rotating plate 30 is perpendicular to the connecting shaft 29, meaning the rotating plate 30 is horizontally arranged.

[0077] The vertical arrangement of the connecting shaft 29 ensures that the rotational motion of the drive motor 28 can be accurately converted into the rotational motion of the rotating plate 30 in the horizontal plane. The horizontal extension direction of the rotating plate 30 allows the second electric push rod 31 mounted on its upper end to rotate with the rotating plate 30 in the horizontal plane to a position directly above the sealing explosion-proof cover 7. This ensures that the extension and retraction direction of the second electric push rod 31 is always consistent with the vertical direction, thereby ensuring that the downward pressure applied by the pressure plate 13 is perpendicular to the upper end face of the sealing explosion-proof cover 7, so that the sealing pressure is evenly distributed and the sealing effect is improved.

[0078] like Figure 6 As shown, Figure 6 This is a cross-sectional schematic diagram of the limiting plate 2 according to some embodiments of this application. In one embodiment, the first end of the limiting block 401 is disposed in the rotating groove 14 via a rotating shaft, and the second end of the limiting block 401 abuts against one side of the movable base 3 when the limiting block 401 is rotated to a vertical position.

[0079] The limiting block 401 has a fan-shaped structure with a rotating shaft as its center of rotation. The first end of the limiting block 401 is a small arc end of the fan shape, which has a shaft hole and is rotatably positioned in the rotating groove 14 via the rotating shaft. The second end of the limiting block 401 is a large arc end of the fan shape. When the limiting block 401 is in an inclined position, the outer edge of the arc is retracted into the rotating groove 14, and when the limiting block 401 rotates around the rotating shaft to a vertical position, it extends out from one side of the rotating groove 14.

[0080] When the operator needs to fix the position of the movable base 3, the limit block 401 is manually moved to rotate around the pivot to a vertical position. The second end of the limit block 401 extends from one side of the rotating groove 14 and abuts against one side of the movable base 3, forming a block and preventing the movable base 3 from moving forward. Subsequently, the movable baffle 402 is located directly above the limit block 401. The operator slides the movable baffle 402 down along the guide plate 403 to a position directly above the limit block 401, so that the lower end face of the movable baffle 402 contacts or approaches the upper end face of the limit block 401. The two sides of the movable baffle 402 slide and engage with the guide plates 403 on both sides, forming a physical block on the rotation path of the limit block 401, thereby limiting the limit block 401 from rotating around the pivot to a non-blocking position and maintaining the locked state of the limit block 401 on the movable base 3. When it is necessary to release the movable base 3, first slide the movable baffle 402 upward along the guide plate 403 to the raised position to release the lock on the limit block 401, and then rotate the limit block 401 around the axis to the tilt position. The second end of the limit block 401 disengages from one side of the movable base 3, and the movable base 3 returns to the movable state.

[0081] The locking and unlocking of the position of the movable base 3 is achieved through the cooperation of the limiting block 401 and the movable baffle 402. The operation is simple and the structure is reliable, preventing the movable base 3 from sliding unexpectedly under unforeseen circumstances and improving the safety of the equipment.
