Description

[Technical Field]

[0001] The present application relates to the technical field of information technology, and more particularly to a lifting mechanism for an immersion-type liquid cooling tank and a lifting system for IT equipment. [Background technology]

[0002] Information technology (IT) equipment such as servers, switches, etc. are well known in the industry. Some IT equipment needs to be placed in cabinets containing cooling fluid, and cranes are required to load and unload the IT equipment during installation and maintenance.

[0003] Currently, conventional cranes typically include a beam-type lifting arm and a bottom support frame. The lifting arm has telescopic struts at both ends connected to the bottom support frame. The bottom of the bottom support frame is equipped with rollers that can move along the ground to load and unload IT equipment at different positions in the cabinet. However, these conventional cranes have problems such as large space requirements and complicated operation. Summary of the Invention [Problem to be solved by the invention]

[0004] Therefore, the present application provides a lifting mechanism for an immersion type liquid cooling tank that aims to improve the convenience of lifting IT equipment and reduce the space occupied by the lifting mechanism for an immersion type liquid cooling tank.

[0005] The present application also provides a lifting system for IT equipment. [Means for solving the problem]

[0006] A first aspect of the present application provides a lifting mechanism for an immersion-type liquid cooling tank used in a cabinet, the lifting mechanism for the immersion-type liquid cooling tank comprising: a guide rail attached to the cabinet; a moving frame that is movably connected to the guide rail and arranged to be reciprocally movable along the extending direction of the guide rail; a hanging arm rotatably connected to the moving frame, the direction of rotation of which is perpendicular to the extending direction of the guide rail; a connection mechanism; the connection mechanism includes a connection member and a drive unit, the connection member being drivably connected to the drive unit; The drive unit is attached to the hanging arm and is used to reciprocate the connecting member along a direction perpendicular to the extending direction of the guide rail.

[0007] In the above embodiment, on the one hand, compared to a conventional crane that moves on the ground, the guide rail can be connected to the rack, and the moving frame can be movably connected to the guide rail. This allows the submersible liquid cooling tank's lifting mechanism to be directly assembled with the cabinet, and the lifting arm can be moved relative to the cabinet to load and unload IT equipment. This eliminates the need for steps such as positioning and calibration between the IT equipment and the cabinet, improves the convenience of operating the submersible liquid cooling tank's lifting mechanism, improves the alignment between the submersible liquid cooling tank's lifting mechanism and the cabinet, and further improves the efficiency and accuracy of loading and unloading IT equipment. On the other hand, compared to a conventional crane that moves on the ground, the submersible liquid cooling tank's lifting mechanism of the present application does not need to be placed on the ground, and the cabinet not only functions as a supporting structure, but also eliminates the need to leave space for the crane to move, which is advantageous in reducing the space occupied by the submersible liquid cooling tank's lifting mechanism.

[0008] In some embodiments, the lifting mechanism for the immersion-type liquid cooling tank further includes a first locking member attached to the moving frame. The first locking member has a first locked state and a first open state. When the first locking member is in the first locked state, the first locking member restricts movement of the moving frame. When the first locking member is in the first open state, the first locking member releases the restriction on the moving frame.

[0009] In the above embodiment, the first locking member is advantageous in reducing the risk of the IT equipment being displaced when the immersion liquid cooling tank's lifting mechanism places the IT equipment in the storage chamber, and is also advantageous in enabling the immersion liquid cooling tank's lifting mechanism to accurately retrieve the IT equipment that needs to be moved, thereby improving the accuracy with which the immersion liquid cooling tank's lifting mechanism completes the loading and unloading of the IT equipment.

[0010] In some embodiments, the first locking member includes an operating portion, a rotating portion, and an abutting portion, which are connected in sequence. The operating portion is located on the side of the moving frame opposite the guide rail. The rotating portion is rotatably attached to the moving frame. The abutting portion is located on the side of the moving frame facing the guide rail. The rotating portion is arranged to move the abutting portion away from the guide rail or toward the guide rail when rotated. When the first locking member is in a first locked state, the abutting portion abuts against the guide rail. When the first locking member is in a first released state, the abutting portion is away from the guide rail.

[0011] In the above embodiment, the operating unit is located on the side of the moving frame away from the guide rail, and the operating unit is located in a large outer space, making it convenient for the operator to control the operating unit or contributing to the connection of the operating unit with other driving structures. In addition, when the moving frame moves to any position on the guide rail, it can be locked, and the fixed position of the moving frame and the hanging arm in the extension direction of the guide rail can be continuously adjusted.

[0012] In some embodiments, the lifting mechanism of the immersion-type liquid cooling tank further includes a second locking member attached to the moving frame. The second locking member has a second locked state and a second open state. When the second locking member is in the second locked state, the second locking member restricts the rotation of the hanging arm. When the second locking member is in the second open state, the second locking member releases the restriction on the hanging arm.

[0013] In the above embodiment, the submersible liquid cooling tank's lifting mechanism can restrict the rotation of the lifting arm using the second locking member when the lifting arm does not need to rotate during the process of transporting IT equipment. First, restricting the rotation of the lifting arm when it does not need to rotate reduces the possibility of the lifting arm rotating or spinning due to external force, thereby reducing the risk of the lifting arm colliding with other structures or injuring workers, thereby improving the safety of the lifting arm. Second, when the submersible liquid cooling tank's lifting mechanism is not transporting IT equipment, the second locking member can fix the angle of the lifting arm at a smaller angle, which is advantageous for reducing the overall space occupied by the submersible liquid cooling tank's lifting mechanism. Third, the second locking member can prevent undesired rotation of the submersible liquid cooling tank's lifting mechanism when transporting IT equipment. This allows the immersion type liquid cooling tank's lifting mechanism to reduce bias during the process of placing IT equipment in the storage room, makes it easier for the immersion type liquid cooling tank's lifting mechanism to accurately retrieve IT equipment that needs to be relocated, and further improves the accuracy of loading and unloading IT equipment using the immersion type liquid cooling tank's lifting mechanism.

[0014] In some embodiments, the second locking member includes a moving lever movably connected to the moving frame and a locking lever connected to the moving lever. A positioning hole is provided in the hanging arm. When the second locking member is in the second lock state, the locking lever enters the positioning hole to restrict the rotation of the hanging arm. When the second locking member is in the second open state, the locking lever exits the positioning hole to release the restriction on the hanging arm.

[0015] The above embodiment has the advantages that the rotation of the hanging arm can be restricted by controlling the movement of the moving lever, the locking system is simple, and the operation is easy.

[0016] In some embodiments, the moving frame includes a slider and a support block, the slider is slidably connected to the guide rail, and the support block is connected to the slider. A guide hole is provided in the support block. The moving lever is movably inserted in the guide hole. The guide hole has a first portion, a second portion, and a third portion that are sequentially connected. When the second locking member is in the second open state, the moving lever is inserted in the first portion. When the second locking member is in the second locked state, the moving lever is inserted in the second portion. Elastic grippers are provided in the first portion and the third portion to clamp the moving lever.

[0017] In the above embodiment, the resilient gripper can provide a damping effect on the moving lever and a force to maintain the moving lever in the first or second portion. This increases the stability of the second locking member in the second locked state and the second open state. Furthermore, since the resilient gripper is not provided in the second portion, the moving lever can more easily move from the first portion to the second portion, or from the third portion to the second portion. Furthermore, since the resilient gripper is not provided in the second portion, the moving lever changes from a state not affected by damping to a state affected by damping when moving from the second portion to the first or third portion. This allows the operator to more easily determine whether the moving lever is in the first or second portion, and further, makes it easier to determine whether the second locking member is in the second locked state or the second open state.

[0018] In some embodiments, the hanging arm includes a first arm and a second arm connected to each other, the first arm is rotatably connected to the moving frame, the extension direction of the second arm is perpendicular to the extension direction of the first arm, and the second arm and the first arm are surrounded to form a retreat space, and the connecting member is located in the retreat space.

[0019] In the above embodiment, the evacuation space is advantageous for storing IT equipment and providing movement space for the IT equipment.

[0020] In some embodiments, the drive unit includes a winch and a connecting wire. The winch is attached to the hanging arm and connected to the connecting wire. The connecting wire is drilled through the second arm and partially extends into the evacuation space. The connecting wire is connected to the connecting member. The winch is arranged to drive the connecting wire when pivoted, thereby reciprocating the connecting member along a direction perpendicular to the extension direction of the guide rail.

[0021] In the above embodiment, the length of the connecting wire in the evacuation space can be adjusted by rotating the winch. Furthermore, the connecting member can be driven to move back and forth along a direction perpendicular to the extending direction of the guide rail. Compared with conventional driving methods such as linear motors, pneumatic cylinders, and hydraulic cylinders, the winch and connecting wire driving method has advantages such as a simple structure, small occupied space, light weight, easy maintenance, and low cost.

[0022] In some embodiments, the evacuation space has a first side and a second side that face each other. The direction in which the first side and the second side face each other, the extension direction of the second arm, and the extension direction of the first arm are perpendicular to each other. The lifting mechanism of the immersion type liquid cooling tank further includes a first reinforcement member and a second reinforcement member. The first reinforcement member is provided on the first side and connected to both the first arm and the second arm. The second reinforcement member is provided on the second side and connected to both the first arm and the second arm.

[0023] In the above embodiment, by providing the first reinforcement on the first side and the second reinforcement on the second side, the first reinforcement and the second reinforcement do not occupy the evacuation space, and the connecting members and IT equipment can be positioned at least partially between the first reinforcement and the second reinforcement, making it possible to make the structure of the lifting mechanism of the submersible liquid cooling tank more compact and reducing the space it occupies.

[0024] A second aspect of the present application provides an IT equipment lifting system including a cabinet and a lifting mechanism for an immersion-type liquid cooling tank according to any of the above-described embodiments. The cabinet includes a first wall and a second wall arranged opposite each other along a first direction. A storage chamber for storing the IT equipment is provided between the first wall and the second wall. An opening is provided in the storage chamber along the second direction. A guide rail of the lifting mechanism for the immersion-type liquid cooling tank is attached to the first wall. The extension direction of the guide rail is defined to be parallel to a third direction. The drive unit is arranged to move the connection member into and out of the storage chamber along the second direction and a direction opposite to the second direction.

[0025] In the above embodiment, the IT equipment lifting system improves the convenience of loading and unloading IT equipment, improves the compatibility between the IT equipment lifting system and the cabinet, and further improves the efficiency and accuracy of loading and unloading IT equipment, and is advantageous in reducing the space occupied by the lifting mechanism of the immersion type liquid cooling tank.

The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the present application.

[0035] This application discloses a lifting mechanism for an immersion-type liquid cooling tank used in a cabinet. The lifting mechanism for the immersion-type liquid cooling tank includes a guide rail, a moving frame, a hanging arm, and a connection mechanism. The guide rail is attached to the cabinet. The moving frame is movably connected to the guide rail and is arranged to be able to move back and forth along the extension direction of the guide rail. The hanging arm is rotatably connected to the moving frame. The rotation direction of the hanging arm is perpendicular to the extension direction of the guide rail. The connection mechanism includes a connection member and a drive unit. The connection member is drivably connected to the drive unit. The drive unit is attached to the hanging arm and is used to move the connection member to move back and forth along a direction perpendicular to the extension direction of the guide rail.

[0036]

[0006] On the one hand, compared to conventional cranes that move on the ground, the aforementioned guide rails can be connected to the rack, and the moving frame can be movably connected to the guide rails. This allows the immersion liquid-cooled tank's lifting mechanism to be directly assembled with the cabinet, and the lifting arm can be moved relative to the cabinet to load and unload IT equipment. This eliminates the need for steps such as positioning and calibration between the IT equipment and the cabinet, improves the ease of operation of the immersion liquid-cooled tank's lifting mechanism, improves the fit between the immersion liquid-cooled tank's lifting mechanism and the cabinet, and further improves the efficiency and accuracy of loading and unloading IT equipment. On the other hand, compared to conventional cranes that move on the ground, the immersion liquid-cooled tank's lifting mechanism of the present application does not need to be placed on the ground, and the cabinet not only functions as a supporting structure, but also eliminates the need to leave space for the crane to move, which is advantageous in reducing the space occupied by the immersion liquid-cooled tank's lifting mechanism.

[0037] Hereinafter, several embodiments of the present application will be described in conjunction with the accompanying drawings. The following embodiments and features in the embodiments may be combined with each other if there is no conflict.

[0038] 1, an IT equipment lifting system 1000 according to an embodiment of the present application includes a cabinet 200 and an immersion-type liquid cooling tank lifting mechanism 100. The cabinet 200 is connected to the immersion-type liquid cooling tank lifting mechanism 100. The immersion-type liquid cooling tank lifting mechanism 100 is used to load or unload an IT device 10a into or from the cabinet 200 (i.e., to remove the IT device 10a from the cabinet 200 or to move the IT device 10a from outside the cabinet 200 into the cabinet 200).

[0039] In some embodiments, the IT equipment 10a includes equipment well known in the industry, such as servers, hosts, displays, switches, routers, mini-machines, etc., which will not be listed here.

[0040] 1 , in some embodiments, a cabinet 200 includes a first wall 201 and a second wall 202 disposed opposite each other along a first direction X. A storage chamber 20a for storing IT equipment 10a is provided between the first wall 201 and the second wall 202. An opening 20b is provided in the storage chamber 20a along a second direction Y. A cooling liquid is disposed in the storage chamber 20a to immerse the IT equipment 10a in the storage chamber 20a. The hoisting mechanism 100 of the submersible liquid cooling tank is used to move the IT equipment 10a from inside the cabinet 200 through the opening 20b or to move the IT equipment 10a from outside the cabinet 200 into the storage chamber 20a.

[0041] 1 , the cabinet 200 further includes a third wall 203, and a fourth wall 204 and a fifth wall 205 arranged opposite each other along the third direction Z. The third wall 203 is located on one side of the first wall 201 and the second wall 202 in the second direction Y. The first wall 201, the second wall 202, the third wall 203, the fourth wall 204, and the fifth wall 205 are surrounded to form the storage chamber 20a. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0042] In some embodiments, as shown in FIG. 2 , the lifting mechanism 100 of the immersion-type liquid cooling tank includes a guide rail 10, a moving frame 20, a hanging arm 30, and a connection mechanism 40. The guide rail 10 is attached to a cabinet 200. The moving frame 20 is movably connected to the guide rail 10 and is arranged to be able to move back and forth along the extension direction of the guide rail 10. The hanging arm 30 is rotatably connected to the moving frame 20. The rotation direction of the hanging arm 30 is perpendicular to the extension direction of the guide rail 10. The connection mechanism 40 includes a connection member 41 and a drive unit 42. The connection member 41 is drivably connected to the drive unit 42. The drive unit 42 is attached to the hanging arm 30 and is used to move the connection member 41 to move back and forth along a direction perpendicular to the extension direction of the guide rail 10.

[0043] For ease of understanding, the following will be described using as an example the workflow when the immersion type liquid cooling tank lifting mechanism 100 leaves the IT equipment outside the cabinet 200 in the accommodation room 20a.

[0044] During movement of the hoisting mechanism 100 for the immersion-type liquid cooling tank, the movable frame 20 moves the hoisting arm 30 to a preset pickup position along the extension direction of the guide rail 10 and rotates the hoisting arm 30 to an upper position outside the cabinet 200. The drive unit 42 then moves the connecting member 41 in a direction perpendicular to the extension direction of the guide rail 10 to connect the connecting member 41 to the IT device 10a outside the cabinet 200. Next, the drive unit 42 moves the connecting member 41 in a direction perpendicular to the extension direction of the guide rail 10 to move the IT device 10a to an upper position outside the cabinet 200. Thereafter, the hoisting arm 30 rotates to rotate the connecting member 41 and the IT device 10a directly above the cabinet 200. Next, the movable frame 20 moves the hoisting arm 30 along the extension direction of the guide rail 10 to a position for placing the IT device 10a. Thereafter, the drive unit 42 moves the connection member 41 in a direction perpendicular to the extending direction of the guide rail 10 , and the connection member 41 moves the IT device 10 a and puts it into the cabinet 200 .

[0045] Of course, the immersion type liquid cooling tank lifting mechanism 100 can remove the IT device 10a from the cabinet 200 in a manner similar to that described above.

[0046] Compared to conventional cranes that move on the ground, the guide rails 10 of the present invention can be connected to a rack, and the movable frame 20 is movably connected to the guide rails 10. This allows the submersible liquid cooling tank lifting mechanism 100 to be directly assembled to the cabinet 200, and the lifting arm 30 can be moved relative to the cabinet 200 to load and unload the IT equipment 10a. This eliminates the need for steps such as positioning and calibration between the IT equipment 10a and the cabinet 200, improving the ease of operation of the submersible liquid cooling tank lifting mechanism 100, improving the fit between the submersible liquid cooling tank lifting mechanism 100 and the cabinet 200, and further improving the efficiency and accuracy of loading and unloading the IT equipment 10a. Moreover, compared to conventional cranes that move on the ground, the submersible liquid cooling tank lifting mechanism 100 of the present invention does not need to be placed on the ground, and the cabinet 200 not only functions as a supporting structure, but also eliminates the need to leave space for the crane to move, which is advantageous in reducing the space occupied by the submersible liquid cooling tank lifting mechanism 100.

[0047] 1 and 2, the extension direction of the guide rail 10 is parallel to the third direction Z, and the direction in which the drive unit 42 reciprocates the connecting member 41 is parallel to the second direction Y. The drive unit 42 is used to move the connecting member 41 into or out of the accommodating chamber 20a through the opening 20b along the second direction Y and the direction opposite to the second direction Y.

[0048] 1 and 2, the guide rail 10 is connected to one side of the cabinet 200 in the first direction X, and is connected to the first wall 201 so that the guide rail 10 enters or exits the accommodation chamber 20a through the opening 20b via the hanging arm 30 along the second direction Y and the direction opposite to the second direction Y. This contributes to the assembly of the immersion-type liquid cooling tank lifting mechanism 100 and the cabinet 200, and the completion of loading and unloading of the IT equipment 10a. This improves the efficiency and accuracy when loading and unloading the IT equipment 10a, and is advantageous in reducing the space occupied by the immersion-type liquid cooling tank lifting mechanism 100.

[0049] In some embodiments, a bearing is provided between the suspension arm 30 and the moving frame 20. The bearing allows the suspension arm 30 and the moving frame 20 to be pivotally connected to each other.

[0050] 2, the connection member 41 includes a hanger rod 411 and a hanger provided on the hanger rod 411. The hanger rod 411 is connected to a connecting wire 422. The IT device 10a can be hung on the hanger.

[0051] In some embodiments, the hanger is provided with a plurality of hooks 412 along the extension direction of the hanger rod 411. The plurality of hooks 412 are spaced apart, which is advantageous for applying the connecting member 41 to IT equipment 10a of different sizes.

[0052] 3 , the lifting mechanism 100 for the immersion type liquid cooling tank further includes a first locking member 50. The first locking member 50 is attached to the moving frame 20 and has a first locked state and a first open state. When the first locking member 50 is in the first locked state, the first locking member 50 restricts the movement of the moving frame 20. When the first locking member 50 is in the first open state, the first locking member 50 releases the restriction on the moving frame 20.

[0053] Furthermore, when movement of the moving frame 20 and the hanging arm 30 becomes unnecessary during the transportation of the IT equipment 10a, the lifting mechanism 100 for the submersible liquid cooling tank can restrict the movement of the moving frame 20 using the first locking member 50, and can also restrict the movement of the hanging arm 30. The first locking member 50 is advantageous in reducing the risk of the IT equipment 10a becoming displaced during the process of the lifting mechanism 100 for the submersible liquid cooling tank leaving the IT equipment 10a in the accommodation chamber 20a, and is advantageous in allowing the lifting mechanism 100 for the submersible liquid cooling tank to accurately retrieve the IT equipment 10a that needs to be relocated. This improves the accuracy of the lifting mechanism 100 for the submersible liquid cooling tank when loading and unloading the IT equipment 10a.

[0054] In some embodiments, as shown in FIG. 3 , the first locking member 50 includes an operating portion 51, a rotating portion 52, and an abutting portion 53, which are connected in sequence. The operating portion 51 is located on the side of the moving frame 20 away from the guide rail 10, in a large outer space. This makes it easy for an operator to control the operating portion 51 and to connect the operating portion 51 to other drive structures. The rotating portion 52 is rotatably attached to the moving frame 20. The abutting portion 53 is located on the side of the moving frame 20 facing the guide rail 10. When the rotating portion 52 rotates, it drives the abutting portion 53 to move toward or away from the guide rail 10. When the first locking member 50 is in the first locked state, the abutting portion 53 abuts against the guide rail 10. When the first locking member 50 is in the first released state, the abutting portion 53 is spaced apart from the guide rail 10.

[0055] When the abutting portion 53 abuts against the guide rail 10, the frictional force between the abutting portion 53 and the guide rail 10 prevents the moving frame 20 from moving, restricting the movement of the moving frame 20 and placing the first locking member 50 in the first locked state. When the abutting portion 53 moves away from the guide rail 10, the frictional force between the abutting portion 53 and the guide rail 10 disappears, the force restricting the movement of the moving frame 20 is released, and the first locking member 50 is placed in the first open state. With the above configuration, the moving frame 20 can be locked when moved to any position on the guide rail 10, and the fixed position of the moving frame 20 and the hanging arm 30 in the extension direction of the guide rail 10 can be continuously adjusted.

[0056] In some embodiments, the rotating part 52 and the moving frame 20 are connected by a screw. For example, the rotating part 52 is a lever member provided with an external thread, and the moving frame 20 is provided with a screw hole that matches the external thread. The rotating part 52 is drilled into a screw hole so that the external thread fits into the internal thread of the screw hole.

[0057] In some embodiments, the contact portion 53 includes an elastic material such as silica gel, rubber, or flexible plastic, which reduces the risk of damage to the contact portion 53 when it contacts the guide rail 10, and further improves the friction force between the contact portion 53 and the guide rail 10.

[0058] 3 and 4, the immersion-type liquid cooling tank lifting mechanism 100 further includes a second locking member 60 attached to the moving frame 20. The second locking member 60 has a second locked state and a second open state. When the second locking member 60 is in the second locked state, the second locking member 60 restricts the rotation of the hanging arm 30. When the second locking member 60 is in the second open state, the second locking member 60 releases the restriction on the hanging arm 30.

[0059] The submersible liquid cooling tank lifting mechanism 100 of the present invention can restrict the rotation of the lifting arm 30 by the second locking member 60 when the lifting arm 30 does not need to rotate during the process of transporting the IT equipment 10a. First, restricting the rotation of the lifting arm 30 when the lifting arm 30 does not need to rotate reduces the possibility of the lifting arm 30 rotating or spinning due to an external force, thereby reducing the risk of the lifting arm 30 colliding with other structures or injuring workers, thereby improving the safety of the lifting arm 30. Second, when the submersible liquid cooling tank lifting mechanism 100 is not transporting the IT equipment 10a, the second locking member 60 can fix the angle of the lifting arm 30 at a smaller angle within the occupied space, which is advantageous in reducing the overall occupied space of the submersible liquid cooling tank lifting mechanism 100. Third, the second locking member 60 can suppress undesirable rotation when the submersible liquid cooling tank's lifting mechanism 100 transports the IT equipment 10a. This reduces bias when the submersible liquid cooling tank's lifting mechanism 100 places the IT equipment 10a in the accommodation chamber 20a, makes it easier for the submersible liquid cooling tank's lifting mechanism 100 to accurately retrieve the IT equipment 10a that needs to be relocated, and further improves the accuracy of the submersible liquid cooling tank's lifting mechanism 100 loading and unloading the IT equipment 10a.

[0060] In some embodiments, as shown in FIGS. 3 and 4 , the second locking member 60 includes a locking lever 61 and a moving lever 62. The locking lever 61 is connected to the moving lever 62. The moving lever 62 is movably connected to the moving frame 20. A positioning hole 311 is provided in the hanging arm 30. When the second locking member 60 is in the second locked state, the locking lever 61 enters the positioning hole 311 and restricts the rotation of the hanging arm 30. When the second locking member 60 is in the second released state, the locking lever 61 retracts from the positioning hole 311 and releases the restriction on the hanging arm 30. The present invention has advantages such as being able to restrict the rotation of the hanging arm 30 by controlling the movement of the moving lever 62, and having a simple locking method and easy operation.

[0061] In some embodiments, as shown in FIGS. 3 to 5 , the moving frame 20 includes a slider 21 and a support block 22. The slider 21 is slidably mounted on the guide rail 10. The support block 22 is connected to the slider 21. A guide hole 221 is provided in the support block 22. The moving lever 62 is movably provided in the guide hole 221. The guide hole 221 has a first portion 2211, a second portion 2212, and a third portion 2213 that are connected in order. When the second locking member 60 is in the second open state, the moving lever 62 is provided in the first portion 2211. When the second locking member 60 is in the second locked state, the moving lever 62 is provided in the second portion 2212. Elastic grippers 25 for clamping the moving lever 62 are provided inside the first portion 2211 and the third portion 2213.

[0062] The elastic gripper 25 can impart a damping effect to the moving lever 62 and can provide a force that maintains the moving lever 62 in the first portion 2211 or the second portion 2212, thereby increasing the stability of the second locking member 60 in the second locked state and the second open state. Furthermore, since the elastic gripper 25 is not provided in the second portion 2212, the moving lever 62 can more easily move from the first portion 2211 to the second portion 2212, or from the third portion 2213 to the second portion 2212. Furthermore, since the elastic gripper is not provided in the second portion, the moving lever 62 changes from a state not affected by damping to a state affected by damping when moving from the second portion 2212 to the first portion 2211 or the third portion 2213. This allows the operator to more easily determine whether the moving lever 62 is in the first part 2211 or the second part 2212, and furthermore, makes it easier to determine whether the second locking member 60 is in the second locked state or the second released state.

[0063] In some embodiments, the elastic gripper 25 may be formed by winding an elastic metal piece, or may employ a structure such as a spring, and is not particularly limited here.

[0064] 4, the moving frame 20 further includes two fixed plates 23 arranged along the second direction Y. The hanging arm 30 is rotatably connected to both of the two fixed plates 23.

[0065] For example, the hanging arm 30 is rotatably connected to two fixed plates 23 via bearings.

[0066] In some embodiments, the moving frame 20 further includes a cover plate 24. The cover plate 24 is provided with non-releasable screws. The cover plate 24 is connected to the two fixed plates 23 by non-releasable screws.

[0067] In some embodiments, as shown in FIGS. 4 and 5 , the guide rail 10 has a collection position 11 and a non-collection position 12. The collection position 11 of the guide rail 10 has an escape hole 111 for accommodating part of the lock lever 61. When the moving frame 20 is in the non-collection position 12, the guide rail 10 stops one end of the lock lever 61 away from the positioning hole 311, preventing the lock lever 61 from retracting from the positioning hole 311. This prevents the hanging arm 30 from rotating when the moving frame 20 is in the non-collection position 12. On the other hand, when the moving frame 20 is in the collection position 11, the lock lever 61 partially enters the escape hole 111, causing the lock lever 61 to retract from the positioning hole 311. This allows the hanging arm 30 to rotate when the moving frame 20 is in the collection position 11. By installing it in this manner, the hanging arm 30 is limited to rotating only at the collection position 11 to collect the IT equipment 10a and then rotating up to above the opening 20b, thereby reducing the risk of the hanging arm 30 colliding with other structures or injuring workers due to the hanging arm 30 rotating at the non-collection position 12, and improving the safety of the hanging arm 30.

[0068] In some embodiments, the shape of the relief hole 111 is arranged to match the lock lever 61 so that the movement of the moving frame 20 can be restricted when the lock lever 61 is inserted into the relief hole 111. This arrangement is advantageous in reducing the possibility that the suspension arm 30 will be moved by an external force, thereby reducing the risk of the suspension arm 30 colliding with other structures or injuring workers, and improving the safety of the suspension arm 30. It is also advantageous in reducing the risk of the immersion-type liquid cooling tank's lifting mechanism 100 shaking when retrieving the IT equipment 10a. It also reduces the risk of the IT equipment 10a becoming displaced when the IT equipment 10a is placed in the accommodation room 20a.

[0069] 4 and 5, the lifting mechanism 100 for the immersion type liquid cooling tank further includes a locking mechanism 90. The locking mechanism 90 includes a connecting plate 91, a first clamp arm 92, a second clamp arm 93, and a fastener 94. The connecting plate 91 is connected to the fixing plate 23. The first clamp arm 92 and the second clamp arm 93 are connected to the connecting plate 91 and are used to clamp the hanging arm 30. The fastener 94 is drilled in the first clamp arm 92 and connected to the second clamp arm 93. The fastener 94 is rotatable relative to the first clamp arm 92, and by moving the second clamp arm 93 in a direction toward or away from the first clamp arm 92, the first clamp arm 92 and the second clamp arm 93 securely clamp the hanging arm 30, restricting the rotation of the hanging arm 30, or releasing the clamping force of the first clamp arm 92 and the second clamp arm 93 on the hanging arm 30 or reducing the clamping force on the hanging arm 30, allowing the hanging arm 30 to rotate.

[0070] 4 and 5, when the moving frame 20 is in the picking position 11, the lock lever 61 enters the relief hole 111 to restrict the movement of the moving frame 20, and then by rotating the fastener 94, the first clamp arm 92 and the second clamp arm 93 can clamp the hanging arm 30 and restrict the rotation of the hanging arm 30. Therefore, stability, accuracy, and safety are improved when the hanging arm 30 lifts the IT equipment 10a.

[0071] In some embodiments, the fastener 94 may be a bolt and handle combination. The first clamp arm 92 has a through hole for the fastener 94 to pass through. The second clamp arm 93 has a threaded hole for connection to the fastener 94.

[0072] In some embodiments, as shown in FIG. 2 , the hanging arm 30 has a first arm 31 and a second arm 32. The first arm 31 is rotatably connected to the moving frame 20. The first arm 31 is connected to the second arm 32. The extension direction of the second arm 32 is perpendicular to the extension direction of the first arm 31. The second arm 32 and the first arm 31 surround each other to form a retraction space 33. The connecting member 41 is located in the retraction space 33. The retraction space 33 accommodates the IT device 10a and provides a space for the IT device 10a to move.

[0073] In some embodiments, the extension direction of the first arm 31 is parallel to the second direction Y, as shown in FIG.

[0074] In some embodiments, the first arm 31 is made up of one link or a plurality of links connected in series. The second arm 32 is also made up of one link or a plurality of links connected in series. However, there is no specific limitation here.

[0075] In some embodiments, as shown in Figure 2, the pick-up position 11 of the guide rail 10 is located at one end of the guide rail 10 along the first direction X, which is advantageous for providing space to accommodate the second arm 32 and preventing the second arm 32 from exceeding the edge of the guide rail 10 in the first direction X when it is rotated. This is advantageous for reducing the overall space occupied by the hoisting mechanism 100 of the immersion-type liquid cooling tank.

[0076] 2 , the drive unit 42 includes a winch 421 and a connecting wire 422. The winch 421 is attached to the hanging arm 30 and connected to the connecting wire 422. The connecting wire 422 is drilled through the second arm 32 and partially extends into the evacuation space 33. The connecting wire 422 is connected to the connecting member 41 described above. The winch 421 is configured to drive the connecting wire 422 when rotated, thereby causing the connecting member 41 to reciprocate along a direction perpendicular to the extension direction of the guide rail 10.

[0077] In the above embodiment, the length of the connecting wire 422 in the evacuation space 33 can be adjusted by rotating the winch 421. Furthermore, the connecting member 41 can be driven to move back and forth along a direction perpendicular to the extension direction of the guide rail 10. Compared with conventional driving methods such as linear motors, pneumatic cylinders, and hydraulic cylinders, the driving method of the winch 421 and connecting wire 422 has advantages such as a simple structure, small occupied space, light weight, easy maintenance, and low cost.

[0078] In some embodiments, as shown in FIG. 2 , the evacuation space 33 has a first side (not shown) and a second side (not shown) that face each other. The direction in which the first side and the second side face each other, the extension direction of the second arm 32, and the extension direction of the first arm 31 are perpendicular to each other. The lifting mechanism 100 for the immersion type liquid cooling tank further includes a first reinforcing member 70 provided on the first side and a second reinforcing member 80 provided on the second side. The first reinforcing member 70 is connected to both the first arm 31 and the second arm 32. The second reinforcing member 80 is connected to both the first arm 31 and the second arm 32.

[0079] The first reinforcing member 70 and the second reinforcing member 80 are advantageous in increasing the stability of the connection between the first arm 31 and the second arm 32 and in increasing the load-bearing capacity of the suspension arm 30. By providing the first reinforcing member 70 on the first side and the second reinforcing member 80 on the second side, the first reinforcing member 70 and the second reinforcing member 80 do not occupy the evacuation space 33, and the connecting member 41 and the IT equipment 10a can be at least partially positioned between the first reinforcing member 70 and the second reinforcing member 80. This makes it possible to make the structure of the immersion-type liquid cooling tank suspension mechanism 100 more compact and reduce the space it occupies.

[0080] In some embodiments, the first stiffener 70 and the second stiffener 80 may be triangular stiffener structures.

[0081] Furthermore, those skilled in the art will understand that the above embodiments are for illustrating the present application, not for limiting the present application, and any appropriate changes or modifications made based on the above embodiments fall within the scope of protection of the present application as long as they do not deviate from the essential spirit of the present invention.
