Description

[Technical Field]

[0001] The present application relates to the technical field of information technology, and in particular to a hoisting mechanism for an immersion liquid-cooled tank and a hoisting system for IT equipment. [Background Art]

[0002] Information technology (IT) equipment such as servers and switches are well known in the industry. Some IT equipment needs to be placed in a cabinet containing a cooling liquid, and a crane is required to realize the loading and unloading of the IT equipment during installation and maintenance of the IT equipment.

[0003] At present, conventional cranes usually include a cross-beam type hanging arm and a bottom support frame. Both ends of the hanging arm are provided with telescopic struts connected to the bottom support frame. Rollers are installed at the bottom of the bottom support frame, which can move on the ground to realize loading and unloading of IT equipment at different positions of the cabinet. Such conventional cranes have problems such as large occupied space and complicated operation. [Summary of the Invention] [Problem to be Solved by the Invention]

[0004] Therefore, the present application provides a hoisting mechanism for an immersion liquid-cooled tank, which aims to improve the convenience of hoisting IT equipment and reduce the occupied space of the hoisting mechanism for the immersion liquid-cooled tank.

[0005] In addition, the present application also provides a hoisting system for IT equipment. [Means for Solving the Problem]

[0006] A first aspect of the present application provides a hoisting mechanism for an immersion liquid-cooled tank used in a cabinet. The hoisting mechanism for the immersion liquid-cooled tank is:[ a guide rail attached to the cabinet; and A movable frame is movably connected to the guide rail and arranged to be able to reciprocate along the extending direction of the guide rail, A suspension arm is rotatably connected to the aforementioned movable frame, and its rotation direction is perpendicular to the extending direction of the guide rail, A connection mechanism is provided. The connection mechanism includes a connecting member and a drive unit, the connecting member being drivably connected to the drive unit, The drive unit is attached to the suspension 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 conventional cranes that move on the ground, the guide rail can be connected to a rack, and the moving frame is movably connected to the guide rail. This allows the lifting mechanism of the immersion liquid-cooled tank to be assembled directly with the cabinet, and the lifting arm can be made movable relative to the cabinet to enable loading and unloading of IT equipment, saving steps such as position adjustment and calibration between the IT equipment and the cabinet, improving the convenience of operating the lifting mechanism of the immersion liquid-cooled tank, improving the compatibility between the lifting mechanism of the immersion liquid-cooled tank and the cabinet, and further improving the efficiency and accuracy when loading or unloading IT equipment. On the other hand, compared to conventional cranes that move on the ground, the lifting mechanism of the immersion liquid-cooled tank of this invention does not need to be placed on the ground, and not only does the cabinet function as a support structure, but it also does not require space to move for the crane, which is advantageous in reducing the space occupied by the lifting mechanism of the immersion liquid-cooled tank.

[0008] In some embodiments, the suspension mechanism for an immersion liquid-cooled tank further includes a first locking member attached to a 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, it restricts the movement of the moving frame. When the first locking member is in the first open state, it releases the restriction on the moving frame.

[0009] In the above embodiment, the first locking member is advantageous in reducing the risk of IT equipment shifting during the process of placing IT equipment into the housing by the suspension mechanism of the immersion liquid-cooled tank, and is also advantageous in enabling the suspension mechanism of the immersion liquid-cooled tank to accurately acquire the IT equipment that needs to be moved. This is advantageous in improving the accuracy of the suspension mechanism of the immersion liquid-cooled tank when completing the loading and unloading of IT equipment.

[0010] In some embodiments, the first locking member includes a sequentially connected operating section, a rotating section, and a contact section. The operating section is located on the side of the moving frame opposite the guide rail. The rotating section is rotatably mounted on the moving frame. The contact section is located on the side of the moving frame facing the guide rail. The rotating section is arranged to move the contact section away from the guide rail or move toward the guide rail when rotating. When the first locking member is in a first locked state, the contact section contacts the guide rail. When the first locking member is in a first open state, the contact section is separated 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, positioning it in a wide space on the outside, which makes it convenient for the operator to control the operating unit or contributes to the connection between the operating unit and other drive structures. Furthermore, the moving frame can be locked when it moves to any position on the guide rail, enabling stepless adjustment of the fixed position of the moving frame and suspension arm in the extending direction of the guide rail.

[0012] In some embodiments, the suspension mechanism for an immersion liquid-cooled tank further includes a second locking member attached to a 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, it restricts the rotation of the suspension arm. When the second locking member is in the second open state, it releases the restriction on the suspension arm.

[0013] In the above embodiment, the suspension mechanism of the immersion liquid-cooled tank can restrict the rotation of the suspension arm by the second locking member when the suspension arm does not need to rotate during the process of transporting IT equipment. In the first aspect, restricting the rotation of the suspension arm when it does not need to rotate reduces the possibility of the suspension arm rotating or spinning due to external forces, thereby reducing the risk of the suspension arm colliding with other structures or injuring workers, and improving the safety of the suspension arm. In the second aspect, when the suspension mechanism of the immersion liquid-cooled tank is not transporting IT equipment, the angle of the suspension arm can be fixed through the second locking member to an angle that occupies a smaller space, which is advantageous in reducing the overall space occupied by the suspension mechanism of the immersion liquid-cooled tank. In the third aspect, the second locking member can suppress undesirable rotation when the suspension mechanism of the immersion liquid-cooled tank is transporting IT equipment. This reduces bias during the process of placing IT equipment into the storage room using the immersion liquid-cooled tank's suspension mechanism, facilitates the accurate acquisition of IT equipment that needs to be moved, and further improves the accuracy of loading and unloading IT equipment using the immersion liquid-cooled tank's suspension mechanism.

[0014] In some embodiments, the second locking member includes a moving lever movably connected to a moving frame and a locking lever connected to the moving lever. The suspension arm is provided with a positioning hole. When the second locking member is in the second locked state, the locking lever retracts into the positioning hole, restricting the rotation of the suspension arm. When the second locking member is in the second open state, the locking lever retracts from the positioning hole, releasing the restriction on the suspension arm.

[0015] The above embodiment has advantages such as being able to restrict the rotation of the suspension arm by controlling the movement of the moving lever, having a simple locking mechanism, and being easy to operate.

[0016] In some embodiments, the movable frame includes a slider and a support block, the slider being slidably connected to a guide rail, and the support block being connected to the slider. The support block is provided with a guide hole. A movable lever is movably drilled into the guide hole. The guide hole has a first, second, and third portion that communicate sequentially. When the second locking member is in the second open state, the movable lever is drilled into the first portion. When the second locking member is in the second locked state, the movable lever is drilled into the second portion. Elastic grips for holding the movable lever are provided in the first and third portions.

[0017] In the above embodiment, the elastic grip can provide a damping effect to the moving lever, and can provide a force to maintain the moving lever in the first or second part. This enhances the stability of the second locking member in the second locked and second open states. Furthermore, since the elastic grip is not provided in the second part, the moving lever can easily move from the first part to the second part, or from the third part to the second part. Also, since the elastic grip is not provided in the second part, when the moving lever moves from the second part to the first or third part, it moves from a state unaffected by damping to a state affected by damping. This makes it easier for the operator to determine whether the moving lever is in the first or second part, and further, it becomes easier to determine whether the second locking member is in the second locked or second open state.

[0018] In some embodiments, the suspension arm has a first arm and a second arm connected to each other, the first arm being rotatably connected to a movable frame, the extension direction of the second arm being perpendicular to the extension direction of the first arm, and the second arm and the first arm surrounding each other to form a retraction space. The aforementioned connecting member is located in this retraction space.

[0019] In the above embodiment, the retraction space is advantageous for housing 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 mounted on a suspension arm and connected to the connecting wire. The connecting wire is drilled into a second arm and partially retracts into a retraction space. The connecting wire is connected to the aforementioned connecting member. The winch is arranged to drive the connecting wire when rotating, causing the connecting member to reciprocate along a direction perpendicular to the extending direction of the guide rail.

[0021] In the above embodiment, the length of the connecting wire in the retraction space can be adjusted by rotating the winch. Furthermore, the connecting member can be driven to reciprocate along a direction perpendicular to the extending direction of the guide rail. Compared to conventional drive systems such as linear motors, pneumatic cylinders, and hydraulic cylinders, the winch and connecting wire drive system has advantages such as a simple structure, small footprint, low weight, easy maintenance, and low cost.

[0022] In some embodiments, the retraction space has opposing first and second sides. The directions in which the first and second sides face each other, the direction of extension of the second arm, and the direction of extension of the first arm are orthogonal to each other. The suspension mechanism of the immersion type liquid-cooled tank further includes a first reinforcing member and a second reinforcing member. The first reinforcing member is provided on the first side and connected to both the first arm and the second arm. The second reinforcing 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 reinforcing member on the first side and the second reinforcing member on the second side, the first and second reinforcing members do not occupy the retraction space, and the connecting members and IT equipment are positioned at least partially between the first and second reinforcing members, thereby making the structure of the suspension mechanism of the immersion type liquid-cooled tank more compact and reducing the occupied space.

[0024] A second aspect of the present application provides a load lifting system for IT equipment, comprising a cabinet and the load lifting mechanism for an immersion liquid-cooled tank according to any one of the above embodiments. The cabinet comprises a first wall and a second wall disposed opposite to each other along a first direction. An accommodation chamber for accommodating IT equipment is provided between the first wall and the second wall. An opening is provided in the accommodation chamber along a second direction. A guide rail of the load lifting mechanism for an immersion liquid-cooled tank is attached to the first wall. It is defined that an extending direction of the guide rail is parallel to a third direction. A drive unit is configured to cause a connecting member to enter into the accommodation chamber or withdraw from the accommodation chamber along the second direction and a direction opposite to the second direction.

[0025] In the above embodiment, the load lifting system for IT equipment improves convenience when loading and unloading IT equipment, improves the matching between the IT equipment load lifting system and the cabinet, further improves the efficiency and accuracy when loading or unloading IT equipment, and is advantageous for reducing the occupied space of the load lifting mechanism for an immersion liquid-cooled tank.

For clarity of the present invention, elements not relevant to the description are omitted from the details herein.

[0034] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those generally understood by those skilled in the art of this application. The terms used herein are for illustrative purposes only and are not intended to limit this application.

[0035] This application discloses a suspension mechanism for an immersion type liquid-cooled tank used in a cabinet. The suspension mechanism for the immersion type liquid-cooled tank includes a guide rail, a moving frame, a suspension arm, and a connecting mechanism. The guide rail is attached to the cabinet. The moving frame is movably connected to the guide rail and is arranged to reciprocate along the extending direction of the guide rail. The suspension arm is rotatably connected to the moving frame. The direction of rotation of the suspension arm is perpendicular to the extending direction of the guide rail. The connecting mechanism includes a connecting member and a drive unit. The connecting member is drivably connected to the drive unit. The drive unit is attached to the suspension arm and is used to move the connecting member to reciprocate along a direction perpendicular to the extending direction of the guide rail.

[0036] 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 is movably connected to the guide rails. This allows the lifting mechanism for the immersion liquid-cooled tank to be assembled directly with the cabinet, and the lifting arm can be made movable relative to the cabinet to enable loading and unloading of IT equipment, saving steps such as position adjustment and calibration between the IT equipment and the cabinet, improving the convenience of operating the lifting mechanism for the immersion liquid-cooled tank, improving the compatibility between the lifting mechanism and the cabinet, and further improving the efficiency and accuracy when loading or unloading IT equipment. On the other hand, compared to conventional cranes that move on the ground, the lifting mechanism for the immersion liquid-cooled tank of this invention does not need to be placed on the ground, and not only does it allow the cabinet to function as a support structure, but it also does not require space to move for the crane, which is advantageous in reducing the space occupied by the lifting mechanism for the immersion liquid-cooled tank.

[0037] Below, several embodiments of the present invention will be described in accordance with the attached drawings. Where there are no conflicts, the following embodiments and their features may be combined with each other.

[0038] As shown in Figure 1, the IT equipment suspension system 1000 according to an embodiment of the present invention includes a cabinet 200 and a suspension mechanism 100 for an immersion liquid-cooled tank. The cabinet 200 is connected to the suspension mechanism 100 for the immersion liquid-cooled tank. The suspension mechanism 100 for the immersion liquid-cooled tank is used to load or unload IT equipment 10a into or from the cabinet 200 (i.e., to remove IT equipment 10a from the cabinet 200 or to move IT equipment 10a from outside the cabinet 200 into the cabinet 200).

[0039] In some embodiments, IT equipment 10a includes industry-known equipment such as servers, hosts, displays, switches, routers, and minimachines, which are not listed here individually.

[0040] In some embodiments, as shown in Figure 1, the cabinet 200 includes a first wall 201 and a second wall 202, which are positioned opposite each other along a first direction X. Between the first wall 201 and the second wall 202 is a housing chamber 20a for housing IT equipment 10a. The housing chamber 20a is provided with an opening 20b along a second direction Y. Cooling liquid is provided inside the housing chamber 20a for immersing the IT equipment 10a inside the housing chamber 20a. A suspension mechanism 100 for an immersion liquid-cooled tank is used to move the IT equipment 10a out of the cabinet 200 through the opening 20b or to move it from outside the cabinet 200 into the housing chamber 20a.

[0041] In some embodiments, as shown in Figure 1, the cabinet 200 further includes a third wall 203, a fourth wall 204, and a fifth wall 205 positioned 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 surround each other to form a storage chamber 20a. The first direction X, the second direction Y, and the third direction Z are orthogonal to each other.

[0042] In some embodiments, as shown in Figure 2, the suspension mechanism 100 for an immersion liquid-cooled tank includes a guide rail 10, a moving frame 20, a suspension arm 30, and a connecting mechanism 40. The guide rail 10 is mounted on a cabinet 200. The moving frame 20 is movably connected to the guide rail 10 and is arranged to reciprocate along the extending direction of the guide rail 10. The suspension arm 30 is rotatably connected to the moving frame 20. The direction of rotation of the suspension arm 30 is perpendicular to the extending direction of the guide rail 10. The connecting mechanism 40 includes a connecting member 41 and a drive unit 42. The connecting member 41 is drivably connected to the drive unit 42. The drive unit 42 is attached to the suspension arm 30 and is used to move the connecting member 41 to reciprocate along a direction perpendicular to the extending direction of the guide rail 10.

[0043] To facilitate understanding, the following example illustrates the workflow when the immersion-type liquid-cooled tank's suspension mechanism 100 leaves IT equipment outside the cabinet 200 in the storage room 20a.

[0044] When the immersion liquid-cooled tank's suspension mechanism 100 moves, the moving frame 20 moves the suspension arm 30 along the extending direction of the guide rail 10 to a preset pickup position, and rotates the suspension arm 30 to the upper outside of the cabinet 200. Then the drive unit 42 moves the connecting member 41 along a direction perpendicular to the extending direction of the guide rail 10 to connect the connecting member 41 to the IT equipment 10a outside the cabinet 200. Next, the drive unit 42 moves the connecting member 41 along a direction perpendicular to the extending direction of the guide rail 10, moving the IT equipment 10a to the upper outside of the cabinet 200. Subsequently, the suspension arm 30 rotates to rotate the connecting member 41 and the IT equipment 10a directly above the cabinet 200. Subsequently, the moving frame 20 moves the suspension arm 30 to a position for positioning the IT equipment 10a along the extending direction of the guide rail 10. Subsequently, the drive unit 42 moves the connecting member 41 along a direction perpendicular to the extending direction of the guide rail 10, and uses the connecting member 41 to move the IT equipment 10a into the cabinet 200.

[0045] Of course, the suspension mechanism 100 of the immersion-type liquid-cooled tank can remove the IT equipment 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 rail 10 of the present invention can be connected to a rack, and the moving frame 20 is movably connected to the guide rail 10. This allows the immersion liquid-cooled tank lifting mechanism 100 to be assembled directly with the cabinet 200, and the suspension arm 30 to be movable relative to the cabinet 200 to enable loading and unloading of IT equipment 10a. This eliminates steps such as position adjustment and calibration between the IT equipment 10a and the cabinet 200, improving the convenience of operating the immersion liquid-cooled tank lifting mechanism 100, improving the compatibility between the immersion liquid-cooled tank lifting mechanism 100 and the cabinet 200, and further improving the efficiency and accuracy when loading or unloading the IT equipment 10a. Moreover, compared to conventional cranes that move on the ground, the immersion liquid-cooled tank lifting mechanism 100 according to the present invention does not need to be placed on the ground, and the cabinet 200 functions as a support structure, and there is no need to leave space for the crane to move, which is advantageous in reducing the space occupied by the immersion liquid-cooled tank lifting mechanism 100.

[0047] In some embodiments, as shown in Figures 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 housing chamber 20a through the opening 20b along the second direction Y and the direction opposite to the second direction Y.

[0048] In some embodiments, as shown in Figures 1 and 2, the guide rail 10 is connected to one side of the cabinet 200 in a first direction X, and is connected to the first wall 201 via a suspension arm 30 to enter into or exit from the storage chamber 20a through an opening 20b along a second direction Y and the direction opposite to the second direction Y. This contributes to the assembly of the immersion liquid-cooled tank suspension mechanism 100 and the cabinet 200, and to the completion of loading and unloading the IT equipment 10a. This increases the efficiency and accuracy when loading or unloading the IT equipment 10a and is advantageous in reducing the space occupied by the immersion liquid-cooled tank suspension mechanism 100.

[0049] In some embodiments, a bearing is interposed between the suspension arm 30 and the movable frame 20. The bearing allows the suspension arm 30 and the movable frame 20 to be rotatably connected relative to each other.

[0050] In some embodiments, as shown in Figure 2, the connecting 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 equipment 10a can be hung on the hanger.

[0051] In some embodiments, the aforementioned hanger is provided with a plurality of hooks 412 along the direction in which the hanger rod 411 extends. 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] In some embodiments, as shown in Figure 3, the suspension mechanism 100 for the immersion liquid-cooled tank further includes a first locking member 50. The first locking member 50 is attached to the movable 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 movable frame 20. When the first locking member 50 is in the first open state, the first locking member 50 releases the restriction on the movable frame 20.

[0053] Furthermore, in the immersion-type liquid-cooled tank's suspension mechanism 100, if the movement of the movable frame 20 and the suspension arm 30 becomes unnecessary during the transfer of IT equipment 10a, the first locking member 50 can restrict the movement of the movable frame 20, and further restrict the movement of the suspension arm 30. The first locking member 50 is advantageous in reducing the risk of the IT equipment 10a shifting during the process of leaving the IT equipment 10a in the storage chamber 20a using the immersion-type liquid-cooled tank's suspension mechanism 100, and is also advantageous in accurately acquiring the IT equipment 10a that needs to be moved by the immersion-type liquid-cooled tank's suspension mechanism 100. This improves the accuracy of the immersion-type liquid-cooled tank's suspension mechanism 100 when loading and unloading IT equipment 10a.

[0054] In some embodiments, as shown in Figure 3, the first locking member 50 includes a sequentially connected operating section 51, a rotating section 52, and a contact section 53. The operating section 51 is located on the side of the moving frame 20 away from the guide rail 10 and in a large outer space. This facilitates the operator's control of the operating section 51 and the connection of the operating section 51 to other drive structures. The rotating section 52 is rotatably mounted on the moving frame 20. The contact section 53 is located on the side of the moving frame 20 facing the guide rail 10. The rotating section 52 is driven to move the contact section 53 toward or away from the guide rail 10 when rotated. When the first locking member 50 is in the first locked state, the contact section 53 is in contact with the guide rail 10. When the first locking member 50 is in the first open state, the contact section 53 is separated from the guide rail 10.

[0055] When the contact portion 53 contacts the guide rail 10, the frictional force between the contact portion 53 and the guide rail 10 prevents the movement of the movable frame 20, thereby limiting the movement of the movable frame 20 and putting the first locking member 50 into a first locked state. When the contact portion 53 separates from the guide rail 10, the frictional force between the contact portion 53 and the guide rail 10 disappears, the force restricting the movement of the movable frame 20 is released, and the first locking member 50 returns to a first open state. With the above configuration, the movable frame 20 can be locked when it moves to any position on the guide rail 10, and stepless adjustment of the fixed position of the movable frame 20 and the suspension arm 30 in the extending direction of the guide rail 10 can be achieved.

[0056] In some embodiments, the rotating part 52 and the movable frame 20 are screw-connected. For example, the rotating part 52 is a lever member with a male screw, and the movable frame 20 is provided with a screw hole that fits the male screw. The rotating part 52 is drilled into the screw hole so that the male screw and the female screw of the screw hole engage.

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

[0058] In some embodiments, as shown in Figures 3 and 4, the suspension mechanism 100 for the immersion type liquid-cooled tank 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, it restricts the rotation of the suspension arm 30. When the second locking member 60 is in the second open state, it releases the restriction on the suspension arm 30.

[0059] In the present invention, when the suspension arm 30 does not need to rotate during the process of transporting IT equipment 10a, the suspension arm 30 can be restricted by the second locking member 60. In the first aspect, restricting the rotation of the suspension arm 30 when it does not need to rotate reduces the possibility of the suspension arm 30 rotating or spinning due to external forces, 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. In the second aspect, when the suspension arm 100 of the immersion type liquid-cooled tank is not transporting IT equipment 10a, the angle of the suspension arm 30 can be fixed through the second locking member 60 to an angle that occupies less space, which is advantageous in reducing the overall space occupied by the suspension arm 30 of the immersion type liquid-cooled tank. In a third respect, the second locking member 60 can suppress undesirable rotation when the immersion liquid-cooled tank's suspension mechanism 100 transports the IT equipment 10a. This reduces deviation during the process of placing the IT equipment 10a into the storage chamber 20a by the immersion liquid-cooled tank's suspension mechanism 100, facilitates the accurate acquisition of the IT equipment 10a that needs to be moved by the immersion liquid-cooled tank's suspension mechanism 100, and further improves the accuracy of loading and unloading the IT equipment 10a by the immersion liquid-cooled tank's suspension mechanism 100.

[0060] In some embodiments, as shown in Figures 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. The suspension arm 30 is provided with a positioning hole 311. When the second locking member 60 is in the second locked state, the locking lever 61 retracts into the positioning hole 311, restricting the rotation of the suspension arm 30. When the second locking member 60 is in the second open state, the locking lever 61 retracts from the positioning hole 311, releasing the restriction on the suspension arm 30. The present invention has advantages such as being able to restrict the rotation of the suspension arm 30 by controlling the movement of the moving lever 62, having a simple locking mechanism, and being easy to operate.

[0061] In some embodiments, as shown in Figures 3 to 5, the movable frame 20 includes a slider 21 and a support block 22. The slider 21 is slidably mounted on a guide rail 10. The support block 22 is connected to the slider 21. The support block 22 is provided with a guide hole 221. A movable lever 62 is movably drilled in the guide hole 221. The guide hole 221 has a first portion 2211, a second portion 2212, and a third portion 2213 that communicate in sequence. When the second locking member 60 is in the second open state, the movable lever 62 is drilled in the first portion 2211. When the second locking member 60 is in the second locked state, the movable lever 62 is drilled in the second portion 2212. Elastic grips 25 for gripping the movable 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 movable lever 62, providing a force that maintains the movable lever 62 in the first part 2211 or the second part 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 part 2212, the movable lever 62 can easily move from the first part 2211 to the second part 2212, or from the third part 2213 to the second part 2212. Also, since the elastic gripper is not provided in the second part, when the movable lever 62 moves from the second part 2212 to the first part 2211 or the third part 2213, it moves from a state unaffected by damping to a state affected by damping. This makes it easier for the operator to determine whether the moving lever 62 is in the first part 2211 or the second part 2212, and also makes it easier to determine whether the second locking member 60 is in the second locked state or the second open state.

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

[0064] In some embodiments, as shown in Figure 4, the movable frame 20 further includes two fixed plates 23 arranged along a second direction Y. The suspension arm 30 is rotatably connected to both fixed plates 23.

[0065] For example, each of the suspension arms 30 is rotatably connected to two fixed plates 23 via bearings.

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

[0067] In some embodiments, as shown in Figures 4 and 5, the guide rail 10 is provided with a sampling position 11 and a non-sampling position 12. The sampling position 11 of the guide rail 10 is provided with a relief hole 111 for accommodating a portion of the lock lever 61. When the movable frame 20 is in the non-sampling 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 exiting the positioning hole 311. As a result, the suspension arm 30 cannot rotate when the movable frame 20 is in the non-sampling position 12. On the other hand, when the movable frame 20 is in the sampling position 11, the lock lever 61 partially enters the relief hole 111, causing the lock lever 61 to exit the positioning hole 311. As a result, the suspension arm 30 can rotate when the movable frame 20 is in the sampling position 11. By installing it in this manner, the suspension arm 30 is restricted to rotating only at the sampling position 11 to sample the IT equipment 10a before rotating above the opening 20b. This reduces the risk of the suspension arm 30 colliding with other structures or injuring workers due to rotation at the non-sampling position 12, thereby improving the safety of the suspension arm 30.

[0068] In some embodiments, the shape of the relief hole 111 is arranged to conform with the lock lever 61 so that the movement of the movable frame 20 is restricted when the lock lever 61 is inserted into the relief hole 111. This arrangement is advantageous in reducing the possibility of the suspension arm 30 being moved by external forces, 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 suspension mechanism 100 of the immersion liquid-cooled tank shaking when the IT equipment 10a is acquired. Furthermore, it reduces the risk of the IT equipment 10a shifting when it is placed in the storage chamber 20a.

[0069] In some embodiments, as shown in Figures 4 and 5, the suspension mechanism 100 of the immersion type liquid-cooled tank further comprises 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 suspension arm 30. The fastener 94 is drilled into 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 toward or toward the first clamp arm 92, the fastener 94 securely clamps the suspension arm 30 with the first clamp arm 92 and the second clamp arm 93 to restrict the rotation of the suspension arm 30, or releases the clamping force on the suspension arm 30 or reduces the clamping force on the suspension arm 30, thereby allowing the suspension arm 30 to rotate.

[0070] As shown in Figures 4 and 5, when the movable frame 20 is in the picking position 11, the lock lever 61 enters the relief hole 111 to restrict the movement of the movable frame 20. Subsequently, by rotating the fastener 94, the first clamp arm 92 and the second clamp arm 93 can clamp the suspension arm 30, restricting the rotation of the suspension arm 30. Therefore, the stability, accuracy, and safety of the suspension arm 30 when lifting the IT equipment 10a are enhanced.

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

[0072] In some embodiments, as shown in Figure 2, the suspension 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 connects to the second arm 32. The extending direction of the second arm 32 is perpendicular to the extending 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 equipment 10a and provides space for the IT equipment 10a to move.

[0073] In some embodiments, as shown in Figure 2, the extension direction of the first arm 31 is parallel to the second direction Y.

[0074] In some embodiments, the first arm 31 consists of a single link or multiple links connected sequentially. The second arm 32 also consists of a single link or multiple links connected sequentially. This is not a specific limitation.

[0075] In some embodiments, as shown in Figure 2, along the first direction X, the take-up position 11 of the guide rail 10 is located at one end of the guide rail 10, which is advantageous in 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 rotated. This is advantageous in reducing the overall space occupied by the suspension mechanism 100 of the immersion liquid-cooled tank.

[0076] In some embodiments, as shown in Figure 2, the drive unit 42 includes a winch 421 and a connecting wire 422. The winch 421 is attached to the suspension arm 30 and connected to the connecting wire 422. The connecting wire 422 is drilled into the second arm 32 and partially extends into the retraction space 33. The connecting wire 422 is connected to the aforementioned connecting member 41. The winch 421 is configured to drive the connecting wire 422 when rotated, causing the connecting member 41 to reciprocate along a direction perpendicular to the extending direction of the guide rail 10.

[0077] In the above embodiment, the length of the connecting wire 422 in the retraction space 33 can be adjusted by rotating the winch 421. Furthermore, the connecting member 41 can be driven to reciprocate along a direction perpendicular to the extending direction of the guide rail 10. Compared to conventional drive systems such as linear motors, pneumatic cylinders, and hydraulic cylinders, the drive system of the winch 421 and connecting wire 422 has advantages such as a simple structure, small footprint, low weight, easy maintenance, and low cost.

[0078] In some embodiments, as shown in Figure 2, the retraction space 33 has opposing first sides (not shown) and second sides (not shown). The directions in which the first and second sides face each other, the direction of extension of the second arm 32, and the direction of extension of the first arm 31 are orthogonal to each other. The suspension mechanism 100 of the immersion type liquid-cooled 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 increasing the load 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 retraction space 33, and the connecting member 41 and the IT equipment 10a can be positioned at least partially between the first reinforcing member 70 and the second reinforcing member 80. This makes the structure of the suspension mechanism 100 for the immersion type liquid-cooled tank more compact and reduces the space it occupies.

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

Appropriate modifications or improvements made based on the above embodiments would fall within the scope of protection of the present invention, provided they do not deviate from the substantial spirit of the present invention.
