Description

Technical Field

[0001] This invention relates to the field of experimental vessel technology, and in particular to a high-pressure sealed experimental vessel. Background Technology

[0002] Before actual use, the designed propeller shaft needs to undergo simulation experiments in its working environment to observe its working status and facilitate the collection of relevant data for improvement.

[0003] Most propeller shaft replacements on ships are performed underwater. Therefore, it is necessary to simulate a high-pressure underwater environment to ensure that the experimental process conforms to the actual scenario. In order to ensure that the experimental process can be carried out stably, most of the experimental equipment adopts a heavy material structure to ensure the safety of the experimental process.

[0004] However, the heavy material structure also limits its operating efficiency. The opening, closing and sealing process of the equipment requires additional equipment assistance. For example, the patent with publication number CN207585813U, entitled "A Pressure Vessel for Deep-Water Experiments", uses multiple fixing nuts to achieve a sealing connection between the high-pressure vessel and the sealing cap. Tightening and loosening of multiple fixing nuts leads to low disassembly and assembly efficiency. Moreover, the sealing effect of fixing the seal with multiple fixing nuts is lower than that of the wrap-around seal, which can easily affect the simulation of the experimental scenario. Summary of the Invention

[0005] The main objective of this invention is to provide a high-pressure sealed test vessel, which aims to improve the efficiency of disassembly and assembly of the test vessel.

[0006] To achieve the above objectives, the present invention provides a high-pressure sealing test vessel, comprising: The tank body, which contains an experimental space; A cap is connected to the tank body and seals the experimental space. A propeller shaft passes through the cap and extends into the experimental space. The propeller shaft is rotatably connected to the cap and seals with the cap. A clamp structure is provided, which is connected to the connection between the tank body and the cap to seal the connection between the tank body and the cap. The clamp structure includes a drive structure and multiple clamp units. The multiple clamp units are arranged in a chain, and adjacent clamp units are rotatably connected by the rotating structure. The multiple clamp units are arranged along the connection between the tank body and the cap. The drive structure is mounted on the surface of the tank body, and the two clamp units at both ends are connected to the drive structure.

[0007] In one embodiment, a first connecting portion protrudes from the outer surface of the can body, and a second connecting portion protrudes from the outer surface of the cap. When the can body and the cap are mated, the first connecting portion and the second connecting portion fit together, and the clamp structure engages with both the first connecting portion and the second connecting portion.

[0008] In one embodiment, the clamp unit is provided with a snap-fit ​​groove, the first connecting part abuts against the second connecting part, and both the first connecting part and the second connecting part are inserted into the snap-fit ​​groove to restrict the cap from detaching from the can body.

[0009] In one embodiment, both clamp units at both ends are connected to a movable structure. The movable structure includes a translation part and a fixed end. The fixed end is fixedly connected to the surface of the clamp unit, and the translation part passes through the fixed end. The driving structure is connected to the translation part.

[0010] In one embodiment, the drive structure includes a drive unit, a bracket, and a transmission shaft. The bracket is mounted on the surface of the tank body, the transmission shaft passes through the bracket and is rotatably connected to the bracket, the output end of the drive unit is connected to the transmission shaft, and the transmission shaft is provided with two sections of threads with opposite helical directions. Both translational parts are penetrated by the drive shaft, and the two translational parts are respectively connected to two sections of thread with opposite helical directions.

[0011] In one embodiment, the rotating structure includes a first extension, a second extension, and a rotating shaft. The first extension is connected to the side of one of the clamp units, and the second extension is connected to the side of another adjacent clamp unit. One end of the first extension and one end of the second extension are rotatably connected through the rotating shaft.

[0012] In one embodiment, the high-pressure sealed test vessel further includes a pressure-applying structure connected to the vessel body and communicating with the test space to adjust the pressure environment of the test space; The pressure-applying structure includes a cooling coil, which is spirally arranged within the experimental space and positioned close to the side wall of the experimental space. The cooling coil is arranged around the propeller shaft, and both ends of the cooling coil pass through the side wall of the tank body for the entry and exit of cooling liquid.

[0013] In one embodiment, the pressure-applying structure further includes an exhaust pipe and an inlet / outlet pipe, the exhaust pipe being disposed on the surface of the tank body, and the inlet / outlet pipe being connected to the surface of the tank body opposite to the exhaust pipe.

[0014] In one embodiment, the high-pressure sealing test tank further includes a detection structure disposed on the surface of the tank body, which detects and outputs data information inside the tank body.

[0015] In one embodiment, the cover has a through hole that connects to the experimental space, and a pressure testing structure is provided inside the through hole, and the pressure testing structure blocks the through hole.

[0016] The technical solution of this invention forms an experimental space by enclosing the tank body and the cap, simulating the operation of a propeller shaft in a deep-water, high-pressure environment, thereby enabling performance testing of the propeller shaft. Furthermore, a chain structure is formed by multiple clamp units rotating and connected to each other, with these clamp units surrounding and fitting the connection between the cap and the tank body. Under the power output of the drive structure, the connection between the cap and the tank body is automatically loosened or tightened, thus automating the sealing and clamping operation between the cap and the tank body. This greatly improves the efficiency of the connection restriction between the cap and the tank body, while the surrounding clamping enhances the connection restriction effect.

[0024] Before actual use, the designed propeller shaft needs to undergo simulation experiments in its working environment to observe its working status and facilitate the collection of relevant data for improvement.

[0025] Most propeller shaft replacements on ships are performed underwater. Therefore, it is necessary to simulate a high-pressure underwater environment to ensure that the experimental process conforms to the actual scenario. In order to ensure that the experimental process can be carried out stably, most of the experimental equipment adopts a heavy material structure to ensure the safety of the experimental process.

[0026] However, the heavy material structure also limits its operating efficiency. The opening, closing and sealing process of the equipment requires additional equipment assistance. For example, the patent with publication number CN207585813U, entitled "A Pressure Vessel for Deep-Water Experiments", uses multiple fixing nuts to achieve a sealing connection between the high-pressure vessel and the sealing cap. Tightening and loosening of multiple fixing nuts leads to low disassembly and assembly efficiency. Moreover, the sealing effect of fixing the seal with multiple fixing nuts is lower than that of the wrap-around seal, which can easily affect the simulation of the experimental scenario.

[0027] This invention proposes a high-pressure sealed experimental vessel.

[0028] Please see Figure 1 In one embodiment of the present invention, the high-pressure sealing test vessel includes: The tank body 10 has an experimental space inside. The cover 50 is connected to the tank body 10 and is sealed in the experimental space. The propeller shaft passes through the cover 50 and extends into the experimental space. The propeller shaft is rotatably connected to the cover 50 and is sealed with the cover 50. The clamp structure 70 is connected to the connection between the tank body 10 and the cover 50 to seal the connection between the tank body 10 and the cover 50. The clamp structure 70 includes a drive structure and multiple clamp units 71. The multiple clamp units 71 are arranged in a chain, and two adjacent clamp units 71 are rotatably connected by a rotating structure 76. The multiple clamp units 71 are arranged along the connection between the tank body 10 and the cover 50. The drive structure is mounted on the surface of the tank body 10, and the two clamp units 71 at both ends are connected to the drive structure.

[0029] like Figure 1 As shown, the experimental space inside the tank body 10 is used to accommodate the propeller shaft, providing space for the scene simulation work of the propeller shaft.

[0030] Meanwhile, the experimental space has an opening on the side of the tank body 10, and the cover 50 is connected to the side of the tank body 10, sealing the opening of the experimental space. It is understandable that by fastening the cap 50 to the tank body 10 and sealing the experimental space, the propeller shaft passes through the cap 50 and extends into the experimental space, and the propeller shaft and the cap 50 are sealed together. In this way, the operating environment of the propeller shaft is simulated in the experimental space, which makes it easier for the experimenter to collect the operating data of the propeller shaft.

[0031] To ensure a good seal after the cap 50 is connected to the tank body 10, such as Figure 3 As shown, a sealing ring 53 is connected to the side of the cap 50 facing the tank body 10.

[0032] It is understandable that when the cap 50 abuts against the side of the can body 10, the sealing ring 53 abuts against the side of the can body 10, and the sealing ring 53 is set around the opening of the experimental space, so as to avoid leakage from the gap between the cap 50 and the can body 10 and thus affect the sealing effect.

[0033] Furthermore, a receiving ring groove 52 is provided on the side of the cap 50 facing the tank body 10, and a sealing ring 53 is provided in the receiving ring groove 52, with part of the sealing ring 53 extending out of the receiving ring groove 52.

[0034] It is understandable that during the process of the cap 50 abutting against the side of the can body 10, the sealing ring 53 partially abuts against the side of the can body 10, and the deformed part of the sealing ring 53 is accommodated by the receiving annular groove 52, so as to avoid affecting the tight fit between the cap 50 and the can body 10.

[0035] In one embodiment, in order to ensure the propeller shaft can pass through, the cover 50 is provided with a through hole at its center, the propeller shaft passes through the through hole, and the propeller shaft and the through hole are sealed and rotatably connected.

[0036] Meanwhile, the side of the cover 50 is provided with an annular protrusion, which is set along the edge of the through hole. When the cover 50 is attached to the tank body 10, the annular protrusion is inserted into the through hole.

[0037] Understandably, the annular protrusion serves as a guide during the process of the cap 50 abutting against the tank body 10, ensuring the efficiency of the connection between the cap 50 and the tank body 10.

[0038] Furthermore, when the annular protrusion is inserted into the can body 10, the side of the annular protrusion facing the can body 10 is inclined to facilitate the insertion of the annular protrusion.

[0039] like Figure 5 As shown, the clamp unit 71 is a single unit, and consists of a first clamp unit, a second clamp unit, and a third clamp unit. The two ends of the second clamp unit are rotatably connected to the first clamp unit and the second clamp unit, thus forming a chain arrangement.

[0040] It should be noted that, in order to facilitate the sealing and fixing between the tank body 10 and the cover 50, and since the cross-sections of the tank body 10 and the cover 50 are both circular, the first clamp unit, the second clamp unit and the third clamp unit together form a circle, and the first clamp unit, the second clamp unit and the third clamp unit are all arc segments.

[0041] Furthermore, one end of the first clamp unit is connected to the drive structure, and one end of the third clamp unit is connected to the drive structure.

[0042] It is understandable that the chain structure formed by the mutual rotation and connection of multiple clamp units 71 is set around the connection between the cover 50 and the tank body 10, and the multiple clamp units 71 fit into the connection between the cover 50 and the tank body 10, thereby improving the sealing effect of the connection between the cover 50 and the tank body 10.

[0043] Understandably, after the cap 50 is connected to the tank body 10, the first clamp unit, the second clamp unit, and the third clamp unit are set around the connection between the cap 50 and the tank body 10. Under the drive of the drive structure, one end of the first clamp unit and one end of the third clamp unit move towards each other, so that the first clamp unit, the second clamp unit, and the third clamp unit gradually tighten and restrict the cap 50 and the tank body 10, so as to ensure the stability of the connection between the cap 50 and the tank body 10.

[0044] When the constraint between the cap 50 and the can body 10 is released, the drive unit outputs power in the direction of the drive unit so that one end of the first clamp unit and one end of the third clamp unit move in opposite directions, thereby causing the first clamp unit, the second clamp unit and the third clamp unit to disengage from the connection between the cap 50 and the can body 10, thus facilitating the removal of the cap 50 from the can body 10.

[0045] It should be noted that when one end of the first clamp unit and one end of the third clamp unit move in opposite directions, that is, the two fixed ends 722 move in opposite directions, and the translation part 721 is rotatably connected to the fixed end 722, so that during the process of the two fixed ends 722 moving in opposite directions, while the translation part 721 translates, the clamp unit 71 automatically rotates relative to the fixed end 722. At this time, while the first clamp unit moves away from the cap 50, the part of the first clamp unit connected to the second clamp unit rotates counterclockwise and moves away from the drive structure. At the same time, the part of the third clamp unit connected to the second clamp unit rotates clockwise and moves away from the drive structure. This allows the second clamp unit to move away from the drive structure and disengage from the connection between the cap 50 and the can body 10. Thus, when the first clamp unit, the second clamp unit, and the third clamp unit are all disengaged from the connection between the cap 50 and the can body 10, the cap 50 can be detached from the can body 10.

[0046] Meanwhile, when it is necessary for the first clamp unit, the second clamp unit, and the third clamp unit to tighten the connection between the cover 50 and the tank body 10, the first clamp unit, the second clamp unit, and the third clamp unit move in the opposite direction to the connection between the cover 50 and the tank body 10 under the power output of the drive structure, thereby achieving a tight and restrictive fit between the cover 50 and the tank body 10.

[0047] The technical solution of this invention forms an experimental space by enclosing the tank body 10 and the cover 50. In the experimental space, the operation of the propeller shaft in a deep-water high-pressure environment is simulated, thereby realizing the performance test of the propeller shaft. Moreover, through the chain structure formed by the mutual rotational connection of multiple clamp units 71, and the multiple clamp units 71 surrounding and fitting the connection between the cover 50 and the tank body 10, the connection between the cover 50 and the tank body 10 is automatically loosened or tightened under the power output of the drive structure. This automatically realizes the sealing and clamping operation between the cover 50 and the tank body 10, which greatly improves the connection restriction efficiency between the cover 50 and the tank body 10. At the same time, the surrounding and fitting clamping improves the connection restriction effect.

[0048] In one embodiment, a first connecting portion 12 protrudes from the outer surface of the can body 10, and a second connecting portion 51 protrudes from the outer surface of the cap 50. When the can body 10 and the cap 50 are connected, the first connecting portion 12 and the second connecting portion 51 fit together, and the clamp structure 70 is engaged with the first connecting portion 12 and the second connecting portion 51.

[0049] like Figure 1As shown, a filling port 11 is provided on the side of the tank body 10 facing the cap 50, a first connecting part 12 is provided on the side of the filling port 11 facing the cap 50, and a second connecting part 51 is provided on the side of the cap 50 facing the tank body 10. When the tank body 10 is connected to the cap 50, the first connecting part 12 and the second connecting part 51 are in contact.

[0050] It is understandable that when multiple clamp units 71 connect the tank body 10 and the cover 50, the multiple clamp units 71 are engaged with the first connecting part 12 and the second connecting part 51, thereby ensuring the sealing and restriction effect of the connection between the tank body 10 and the cover 50.

[0051] Furthermore, the first connecting part 12 is arranged around the tank body 10, and the second connecting part is arranged around the cover 50, so that the chain-type multiple clamp units 71 arranged around the tank body 10 and the cover 50 can surround the first connecting part 12 and the second connecting part, thereby realizing the surrounding clamping restriction of the cover 50 and the tank body 10 and improving the clamping sealing efficiency.

[0052] In one embodiment, the clamp unit 71 is provided with a snap-fit ​​groove 711, the first connecting part 12 abuts against the second connecting part 51, and both the first connecting part 12 and the second connecting part 51 are inserted into the snap-fit ​​groove 711 to restrict the cap 50 from detaching from the can body 10.

[0053] like Figure 1 As shown, in order to facilitate the clamp unit 71 in restricting the first connecting part 12 and the second connecting part 51, a snap-fit ​​groove 711 is provided on the side of the clamp unit 71 facing the first connecting part 12 and the second connecting part 51.

[0054] It is understandable that when multiple clamping units 71 clamp the first connecting part 12 and the second connecting part 51 together, the first connecting part 12 and the second connecting part 51 are embedded in the clamping groove 711, and the opposite sidewalls of the clamping groove 711 abut against the first connecting part 12 and the second connecting part 51 respectively, thereby achieving the function of restricting the tank body 10 and the cap 50.

[0055] Furthermore, when multiple clamp units 71 restrict the connection between the tank body 10 and the cap 50 along the outer contour of the tank body 10, the snap-fit ​​grooves 711 on the multiple clamp units 71 jointly restrict the first connecting part 12 and the second connecting part 51. In this way, by restricting the first connecting part 12 and the second connecting part 51 in all directions, the restriction effect and quality are improved while ensuring operational efficiency.

[0056] In order to facilitate the first connecting part 12 and the second connecting part 51 to be fitted into the snap-fit ​​groove 711, the side wall of the opening of the snap-fit ​​groove 711 is in an inclined state, so as to enlarge the opening of the snap-fit ​​groove 711 and facilitate the entry of the first connecting part 12 and the second connecting part 51.

[0057] Furthermore, in order to facilitate the compatibility of the first connecting part 12 and the second connecting part 51 with the snap-fit ​​groove 711, the side of the first connecting part 12 facing away from the second connecting part 51 and the side of the second connecting part 51 facing away from the first connecting part 12 are both beveled, so as to facilitate the insertion and engagement of the first connecting part 12 and the second connecting part 51.

[0058] During the process of clamp unit 71 engaging with first connecting part 12 and second connecting part 51, the enlarged opening of the engaging groove 711, the inclined side of first connecting part 12 away from second connecting part 51, and the inclined side of second connecting part 51 away from first connecting part 12 cooperate with each other, enabling first connecting part 12 and second connecting part 51 to stably and quickly engage with clamp unit 71, thereby improving the efficiency of clamp.

[0059] In one embodiment, both clamp units 71 at both ends are connected to a movable structure 72. The movable structure 72 includes a translation part 721 and a fixed end 722. The fixed end 722 is fixedly connected to the surface of the clamp unit 71, and the translation part 721 passes through the fixed end 722. The driving structure is connected to the translation part 721.

[0060] like Figure 5 As shown, both the first clamp unit and the third clamp unit are connected to the moving structure 72, and the driving structure is connected to the moving structure 72.

[0061] Understandably, the drive structure outputs power to move the moving structure 72, thereby causing the first clamp unit and the third clamp unit to move towards or away from each other, so that the multiple clamp units arranged in a ring-like chain can tighten or loosen the can body 10 and the cover 50.

[0062] In one embodiment, the fixed end is connected to the drive structure, the translation part 721 is connected to the clamp unit, the translation part 721 passes through the fixed end and is rotatably connected to the fixed end.

[0063] It is understandable that when the drive structure outputs power to move the first clamp unit and the third clamp unit toward or away from each other, the fixed end translates and drives the translation part to translate. Since the fixed end and the translation part 721 are rotatably connected, the translation part 721 and the clamp unit 71 rotate under the weight of the clamp unit 71. Thus, both the first clamp unit and the third clamp unit rotate, which makes it easier for the second clamp unit to move closer to or away from the connection between the tank body 10 and the cover 50. This allows the first clamp unit and the third clamp unit to automatically tighten or loosen the clamp between the tank body 10 and the cover 50.

[0064] In one embodiment, the drive structure includes a drive unit 75, a bracket 74 and a drive shaft 73. The bracket 74 is mounted on the surface of the tank body 10, the drive shaft 73 passes through the bracket 74 and is rotatably connected to the bracket 74, the output end of the drive unit 75 is connected to the drive shaft 73, and the drive shaft 73 is provided with two sections of threads with opposite helical directions. Both fixed ends 722 are penetrated by the drive shaft 73, and the two fixed ends 722 are respectively connected to two sections of threads with opposite helical directions.

[0065] like Figure 5 As shown, bracket 74 is mounted on the upper surface of tank body 10 to provide support for drive shaft 73 and drive unit 75.

[0066] It is understandable that the two fixed ends 722 are respectively set on the threads with opposite helical directions at both ends of the transmission shaft 73, so that the two fixed ends 722 can move towards each other or away from each other during the rotation of the transmission shaft 73.

[0067] Furthermore, when the drive unit 75 outputs power, it drives the transmission shaft 73 to rotate, thereby facilitating the movement of the two fixed ends 733 towards or away from each other, thereby driving the two translation units 721 to move.

[0068] In another embodiment, the drive unit 75 is a motor.

[0069] It should be noted that the output end of the drive unit 75 is directly connected to the transmission shaft 73, so that the transmission shaft 73 can be directly driven to rotate.

[0070] It should be noted that the output end of the drive unit 75 is connected to the drive shaft 73 through a transmission structure to facilitate the installation and connection of the drive unit 75.

[0071] It is understandable that the transmission structure can be a bevel gear transmission structure, and when the transmission shaft 73 and the drive unit 75 are set at an angle, transmission can be achieved through the bevel gear transmission structure.

[0072] Furthermore, such as Figure 4 As shown, the bracket 74 is a frame structure, the drive shaft 73 passes through the bracket 74, the fixed end 722 and the translation part 721 are both surrounded by the bracket 74, and the drive part 75 is connected to the outer side of the bracket 74. The drive part 75 can be directly connected to the drive shaft 73, or the drive part 75 can be connected to the drive shaft 73 through a transmission structure.

[0073] In one embodiment, the rotating structure 76 includes a first extension 761, a second extension 763, and a rotating shaft 762. The first extension 761 is connected to the side of a clamp unit 71, and the second extension 763 is connected to the side of another adjacent clamp unit 71. One end of the first extension 761 and one end of the second extension 763 are rotatably connected by the rotating shaft 762.

[0074] like Figure 5 As shown, the rotating structure 76 is used to connect the first clamp unit and the second clamp unit, as well as the second clamp unit and the third clamp unit.

[0075] Understandably, the first extension 761 is connected to the side of the first clamp unit and is close to the second clamp unit, and the second extension 763 is connected to the side of the second clamp unit and is close to the first clamp unit. The first extension 761 and the second extension 763 are connected by a pivot 762.

[0076] It is understandable that when the first clamp unit rotates during the translation of the fixed end 722, that is, when the first clamp unit moves away from the direction of the cover 50, the end of the first clamp unit away from the drive shaft 73 rotates towards the direction of the cover 50. In conjunction with the rotation of the third clamp unit on the other side, the second clamp unit moves away from the cover 50, so as to facilitate the separation of multiple clamp units from the tank body 10.

[0077] In one embodiment, one end of the first extension 761 and one end of the second extension 763 are arranged in parallel and connected by a pivot 762.

[0078] In another embodiment, one end of the first extension 761 is inserted into the second extension 763 and connected by a pivot 762, or one end of the second extension 763 is inserted into the first extension 761 and connected by a pivot 762.

[0079] It is understood that the first extension 761 and the second extension 763 are rotatably connected by a pivot 762, so that the second clamp unit can be moved synchronously during the translation of the first clamp unit and the third clamp unit at the two fixed ends 722, thereby facilitating the tightening or loosening of the tank body 10 and the cover 50.

[0080] In one embodiment, the high-pressure sealing test vessel further includes a pressure-applying structure 30, which is connected to the vessel body 10 and communicates with the test space to adjust the pressure environment of the test space. The pressure-applying structure 30 includes a cooling coil 33, which is spirally arranged in the experimental space and close to the side wall of the experimental space. The cooling coil 33 is arranged around the propeller shaft, and both ends of the cooling coil 33 pass through the side wall of the tank body 10 for the entry and exit of cooling liquid.

[0081] During the testing of the propeller shaft, the propeller shaft is constantly rotating, and the operation generates heat, which can disrupt the simulated scene in the experimental space.

[0082] Therefore, a cooling coil 33 is installed in the experimental space, and the cooling coil 33 is arranged around the propeller shaft.

[0083] It is understandable that the coolant flows inside the cooling coil 33, and the heat generated by the propeller shaft operation exchanges with the cooling coil 33 to achieve heat dissipation and cooling.

[0084] It should be noted that both ends of the cooling coil 33 are inserted into the tank body 10, and the two ends of the cooling coil 33 are used as liquid inlet and liquid outlet, and valve ports are provided at both liquid inlet and liquid outlet.

[0085] In one embodiment, the pressure-applying structure 30 further includes an exhaust pipe 31 and an inlet / outlet pipe 32. The exhaust pipe 31 is disposed on the surface of the tank body 10, and the inlet / outlet pipe 32 is connected to the surface of the tank body 10 opposite to the exhaust pipe 31.

[0086] In order to make the test results closely resemble the actual situation during the testing of the propeller shaft, it is necessary to simulate the operating scenario in the experimental space.

[0087] Understandably, when the tank body 10 and the cap 50 are fastened and sealed, water is injected into the experimental space by setting the inlet and outlet pipes 32, and the gas in the experimental space is discharged through the exhaust pipe 31. The method of injecting water and pressurizing in the experimental space simulates the operating scenario of a propeller shaft in the experimental space, so as to ensure that the experimental results are close to reality and ensure the accuracy of the test results.

[0088] In one embodiment, the high-pressure sealing test tank further includes a detection structure 20, which is disposed on the surface of the tank body 10 and detects and outputs data information inside the tank body 10.

[0089] It is understood that the detection structure 20 includes a temperature measuring unit 21, a local pressure testing unit 22, and a remote pressure testing unit 23.

[0090] Temperature measurement unit 21, local pressure testing unit 22 and remote pressure testing unit 23 are all connected to the experimental space. It can be understood that temperature measurement unit 21 is used to detect the temperature in the experimental space, and local pressure testing unit 22 and remote pressure testing unit 23 are used to detect the pressure in the experimental space.

[0091] Understandably, the data outputs from the temperature measurement unit 21, the local pressure testing unit 22, and the remote pressure testing unit 23 are as follows.

[0092] In one embodiment, the cover 50 is provided with a through hole that connects to the experimental space. A pressure testing structure is provided inside the through hole, and the pressure testing structure blocks the through hole.

[0093] It should be noted that, since the experimental space is under high pressure during the experiment, if the pressure in the experimental space is not released when the cap 50 needs to be separated from the main body 10, the high pressure situation may pose a danger.

[0094] Therefore, such as Figure 2 As shown, a through hole is provided on the cover 50, and a pressure test structure is provided in the through hole. The clamp structure 70 is only unlocked when the pressure test structure 60 detects that the pressure in the experimental space is in a normal state.

[0095] The pressure testing structure includes an internal pressure testing section 62, a first connector 63, and a second connector 61. The internal pressure testing section 62 is inserted into a through hole, the second connector 61 is connected to a bracket 74, and the first connector 63 is connected to the second connector 61 and the internal pressure testing section 62.

[0096] Understandably, the first connector 63 and the second connector 61 are used to fix the internal pressure testing unit 62.

[0097] In another embodiment, the can body 10 is disposed on a base surface, and a guide rail translation structure 40 for connecting the cover 50 is also provided on the base surface. The guide rail translation structure 40 is connected to the cover 50.

[0098] Understandably, the guide rail translation structure 40 is used to drive the cap 50 closer to or further away from the tank body 10.

[0099] Furthermore, the guide rail translation structure 40 includes a guide rail 41 and a support frame 42. The guide rail 41 is disposed on the base surface, and the support frame 42 is connected to the side of the cover 50 away from the tank body 10. The support frame 42 is connected to the guide rail 41 and can move along the guide rail 41.

[0100] Understandably, a power unit is provided on the guide rail 41 to drive the support frame 42 to move on the guide rail 41.

[0101] Understandably, when it is necessary to control the movement of the cap 50, the power unit outputs power, causing the support frame to drive the cap 50 to move along the guide rail 41, thereby achieving the connection or disconnection of the cap 50 from the tank body 10.

[0102] The above description is merely an exemplary embodiment of the present invention and does not limit the scope of protection of the present invention. Any equivalent structural transformations made based on the technical concept of the present invention and the contents of the specification and drawings of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of protection of the present invention.
