Description

Technical Field

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

[0002] Information technology ("IT") equipment such as servers and switches is well known in the industry. Some IT equipment needs to be placed in cabinets equipped with coolants. Cranes are often required to place and maintain IT equipment.

[0003] Conventional cranes typically consist of a beam-type lifting arm and a base support frame. Each end of the arm has telescopic struts connected to the base support frame. The base support frame is equipped with rollers to enable ground movement and to place IT equipment in and out of different cabinet locations. These conventional cranes have the disadvantages of large space requirements and complex operation. Summary of the Invention

[0004] In view of this, the present application provides an immersion liquid refrigerator hanging mechanism, which aims to improve the convenience of IT equipment hanging and help reduce the space occupied by the immersion liquid refrigerator hanging mechanism.

[0005] In addition, the present application also provides an IT equipment lifting system.

[0006] A first aspect of the present application provides an immersion liquid refrigerator lifting mechanism for a cabinet, the immersion liquid refrigerator lifting mechanism comprising a guide rail, a movable frame, a lifting arm and a connecting structure. The guide rail is used to be installed on the cabinet. The movable frame is movably connected to the guide rail, and the movable frame is configured to be able to move back and forth along the extension direction of the guide rail. The lifting arm is rotatably connected to the movable frame, and the rotation axis of the lifting arm is perpendicular to the extension direction of the guide rail. The connecting structure comprises a connecting member and a drive assembly, the connecting member is transmission-connected to the drive assembly, the drive assembly is mounted on the lifting arm, and the drive assembly is used to drive the connecting member to move back and forth in a direction perpendicular to the extension 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 rails can be connected to the rack, and the mobile rack is movably connected to the guide rails, so that the immersion liquid refrigerator lifting mechanism can be directly assembled with the cabinet, and the lifting arm can be movable relative to the cabinet to complete the loading and unloading of IT equipment, saving the steps of position adjustment and calibration between the cabinet, which is conducive to improving the convenience of operation of the immersion liquid refrigerator lifting mechanism, and also makes the immersion liquid refrigerator lifting mechanism and the cabinet better matched, thereby helping to improve 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 immersion liquid refrigerator lifting mechanism of the present application does not need to be placed on the ground, so that the cabinet acts as a supporting structure and there is no need to reserve space for the crane to move, which is conducive to reducing the space occupied by the immersion liquid refrigerator lifting mechanism.

[0008] In some embodiments, the immersion liquid refrigerator lifting mechanism also includes a first locking member, which is installed on the movable frame. The first locking member has a first locking state and a first open state. When the first locking member is in the first locking state, the first locking member restricts the movement of the movable frame. When the first locking member is in the first open state, the first locking member releases the restriction on the movable frame.

[0009] In the above embodiment, the first locking member helps to reduce the risk of the immersion liquid refrigerator lifting mechanism being placed off-center during the process of placing IT equipment in the storage compartment, and also helps the immersion liquid refrigerator lifting mechanism accurately obtain the IT equipment to be transferred, thereby helping to improve the accuracy of the immersion liquid refrigerator lifting mechanism in completing the loading and unloading of IT equipment.

[0010] In some embodiments, the first locking member includes an operating portion, a rotating portion, and an abutting portion connected in sequence. The operating portion is located on a side of the movable frame facing away from the guide rail, the rotating portion is rotatably mounted on the movable frame, and the abutting portion is located on a side of the movable frame facing the guide rail. The rotating portion is configured to move the abutting portion away from or toward the guide rail when rotating. When the first locking member is in a first locked state, the abutting portion abuts the guide rail, and when the first locking member is in a first unlocked state, the abutting portion is separated from the guide rail.

[0011] In the above embodiment, the operating unit is located on the side of the mobile frame facing away from the guide rail, leaving the operating unit in a larger outer space. This facilitates operator control of the operating unit and facilitates connection between the operating unit and other drive mechanisms. Furthermore, the mobile frame can be locked at any position on the guide rail, enabling stepless adjustment of the fixed position of the mobile frame and the lifting arm along the extension direction of the guide rail.

[0012] In some embodiments, the immersion liquid refrigerator lifting mechanism also includes a second locking member, which is installed on the movable frame. The second locking member has a second locking state and a second open state. When the second locking member is in the second locking state, the second locking member restricts the rotation of the lifting arm. When the second locking member is in the second open state, the second locking member releases the restriction on the lifting arm.

[0013] In the above embodiment, when the lifting arm of the immersion cooler is transferring IT equipment, the second locking member can be used to restrict the rotation of the lifting arm when the lifting arm does not need to rotate. First, restricting the rotation of the lifting arm when it does not need to rotate helps reduce the possibility of the lifting arm being rotated by external forces or rotating on its own, thereby reducing the risk of the lifting arm colliding with other structures or causing injury to operators, and improving the safety of the lifting arm. Second, when the immersion cooler lifting mechanism is not transferring IT equipment, the second locking member can be used to fix the angle of the lifting arm at a smaller angle, thereby reducing the overall space occupied by the immersion cooler lifting mechanism. Third, the second locking member can inhibit the immersion cooler lifting mechanism from undesired rotation when transferring IT equipment, thereby reducing the risk of the immersion cooler lifting mechanism shifting when placing IT equipment in the storage compartment, and further helping the immersion cooler lifting mechanism accurately obtain the IT equipment to be transferred, thereby improving the accuracy of the immersion cooler lifting mechanism in completing the loading and unloading of IT equipment.

[0014] In some embodiments, the second locking member includes a locking rod and a movable rod, the locking rod being connected to the movable rod, and the movable rod being movably connected to the movable frame. The hanging arm is provided with a positioning hole. When the second locking member is in a second locking state, the locking rod drives the locking rod to extend into the positioning hole to restrict rotation of the hanging arm. When the second locking member is in a second unlocking state, the locking rod exits the positioning hole to release the restriction on the hanging arm.

[0015] In the above embodiment, the rotation of the lifting arm can be restricted by controlling the movement of the moving rod, which has the advantages of a simple locking method and easy operation.

[0016] In some embodiments, the movable frame includes a slider and a support block, the slider being slidably connected to the guide rail, the support block being connected to the slider, and the support block being provided with a guide hole. The movable rod is movably disposed in the guide hole, and the guide hole comprises 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 movable rod is disposed in the first portion, and when the second locking member is in the second locked state, the movable rod is disposed in the second portion. Both the first portion and the third portion are provided with elastic clamping members for clamping the movable rod.

[0017] In the above embodiment, the elastic clamping member can exert a damping effect on the moving rod, and can provide a force to maintain the moving rod in the first part or the second part, thereby improving the stability of the second locking member in the second locked state and the second open state. In addition, the second part is not provided with an elastic clamping member, which helps to reduce the ease of the moving rod entering the second part from the first part or entering the second part from the third part. The second part is not provided with an elastic clamping member, and it can also allow the moving rod to enter the first part or the third part from a state not affected by damping when the second part enters the first part or the third part, so that the operator can more easily determine whether it has entered the first part or the second part, and further make it easier for the operator to determine whether the second locking member is in the second locked state or the second open state.

[0018] In some embodiments, the lifting arm has a first arm and a second arm, the first arm is rotatably connected to the movable frame, the first arm is connected to the second arm, the extension direction of the second arm is perpendicular to the extension direction of the first arm, and an avoidance space is provided around the second arm and the first arm; the connecting member is located in the avoidance space.

[0019] In the above embodiment, the avoidance space is conducive to accommodating IT equipment and providing space for the IT equipment to move.

[0020] In some embodiments, the drive assembly includes a winch and a connecting cable. The winch is mounted on the lifting arm and connected to the connecting cable. The connecting cable is routed through the second arm and partially extends into the escape space. The connecting cable is connected to the connector. The winch is configured to rotate to drive the connecting cable, thereby driving the connector to reciprocate in a direction perpendicular to the extension direction of the guide rail.

[0021] In the above embodiment, the length of the free space connecting line can be adjusted by rotating the capstan, thereby driving the connecting member to reciprocate in a direction perpendicular to the extension direction of the guide rail. Compared to drive methods such as linear motors, pneumatic cylinders, and hydraulic cylinders, the capstan and connecting line drive method has the advantages of simple structure, small space occupation, low weight, easy maintenance, and low cost.

[0022] In some embodiments, the avoidance space has a first side and a second side that are opposite to each other, and the direction in which the first side and the second side are opposite to each other, the direction in which the second arm extends, and the direction in which the first arm extends are perpendicular to each other. The immersion liquid refrigerator lifting mechanism further includes a first reinforcement member and a second reinforcement member, the first reinforcement member being disposed on the first side and connected to both the first arm and the second arm, and the second reinforcement member being disposed on the second side and connected to both the first arm and the second arm.

[0023] In the above embodiment, by arranging the first reinforcement member on the first side and the second reinforcement member on the second side, the first reinforcement member and the second reinforcement member do not occupy the avoidance space, so that the connector and the IT equipment can be at least partially located between the first reinforcement member and the second reinforcement member. In this way, the structure of the immersion liquid cooler lifting mechanism can be more compact and occupy less space.

[0024] A second aspect of the present application further provides an IT equipment lifting system, comprising a cabinet and the immersion liquid cooler lifting mechanism of any of the aforementioned embodiments. The cabinet comprises a first wall and a second wall disposed opposite each other along a first direction, a compartment for accommodating IT equipment disposed between the first and second walls, the compartment having an opening along a second direction. A guide rail of the immersion liquid cooler lifting mechanism is mounted on the first wall, with the guide rail extending in a direction parallel to the third direction. The drive assembly is configured to drive a connector to enter and exit the compartment along the second direction and a direction opposite the second direction.

[0025] The above embodiment is conducive to improving the convenience of the IT equipment lifting system when taking IT equipment off and on the shelves, and also makes the matching between the IT equipment lifting system and the cabinet better, thereby helping to improve the efficiency and accuracy of taking IT equipment off and on the shelves, and also helping to reduce the space occupied by the immersion liquid refrigerator lifting mechanism.

In order to make the present invention clear, elements not related to the description are omitted from the details of this specification.

[0093] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0094] The present application discloses a lifting mechanism for an immersion liquid refrigerator, which is used for a cabinet. The lifting mechanism for the immersion liquid refrigerator includes a guide rail, a movable frame, a lifting arm, and a connecting structure. The guide rail is used to be installed in the cabinet. The movable frame is movably connected to the guide rail, and the movable frame is configured to be able to move back and forth along the extension direction of the guide rail. The lifting arm is rotatably connected to the movable frame, and the rotation axis of the lifting arm is perpendicular to the extension direction of the guide rail. The connecting structure includes a connecting member and a drive assembly. The connecting member is transmission-connected to the drive assembly. The drive assembly is installed on the lifting arm, and the drive assembly is used to drive the connecting member to move back and forth in a direction perpendicular to the extension direction of the guide rail.

[0095] On the one hand, compared to conventional cranes that move on the ground, the guide rails can be connected to the racks, and the mobile racks can be movably connected to the guide rails, so that the immersion liquid freezer lifting mechanism can be directly assembled with the cabinets, and the lifting arm can be movable relative to the cabinets to complete the loading and unloading of IT equipment, saving the steps of position adjustment and calibration between the cabinets, which is conducive to improving the convenience of operation of the immersion liquid freezer lifting mechanism, and also makes the immersion liquid freezer lifting mechanism and the cabinet better matched, thereby helping to improve 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 freezer lifting mechanism of the present application does not need to be placed on the ground, so that the cabinets serve as a supporting structure and there is no need to reserve space for the crane to move, which is conducive to reducing the space occupied by the immersion liquid freezer lifting mechanism.

[0096] The following will describe some embodiments of the present application in conjunction with the accompanying drawings. In the absence of conflict, the following embodiments and features in the embodiments may be combined with each other.

[0097] See also Figure 1 An embodiment of the present application provides an IT equipment lifting system 1000, which includes a cabinet 200 and an immersion liquid refrigerator lifting mechanism 100. The cabinet 200 is connected to the immersion liquid refrigerator lifting mechanism 100, and the immersion liquid refrigerator lifting mechanism 100 is used to remove and load IT equipment 10a from the cabinet 200 (i.e., to move the IT equipment 10a out of the cabinet 200 or to move the IT equipment 10a from outside the cabinet 200 to inside the cabinet 200).

[0098] In some embodiments, the IT equipment 10a includes a server, a host, a display, a switch, a router, a minicomputer, etc. The IT equipment 10a is well known in the industry and will not be listed one by one here.

[0099] In some embodiments, see Figure 1 The cabinet 200 includes a first wall 201 and a second wall 202 arranged opposite each other along a first direction X. A storage compartment 20a for accommodating IT equipment 10a is located between the first wall 201 and the second wall 202. The storage compartment 20a has an opening 20b along a second direction Y. Coolant is provided in the storage compartment 20a to immerse the IT equipment 10a therein. The immersion liquid cooler mounting mechanism 100 is used to remove the IT equipment 10a from the cabinet 200 through the opening 20b or to move it from outside the cabinet 200 into the storage compartment 20a.

[0100] In some embodiments, see Figure 1 The cabinet 200 further includes a third wall 203 located on one side of the first wall 201 and the second wall 202 in the second direction Y, and a fourth wall 204 and a fifth wall 205 disposed opposite each other along the third direction Z. The first wall 201, the second wall 202, the third wall 203, the fourth wall 204, and the fifth wall 205 enclose a storage compartment 20a. The first direction X, the second direction Y, and the third direction Z are perpendicular to each other.

[0101] In some embodiments, see Figure 2The immersion liquid refrigerator lifting mechanism 100 includes a guide rail 10, a movable frame 20, a lifting arm 30 and a connecting structure 40. The guide rail 10 is installed on the cabinet 200, the movable frame 20 is movably connected to the guide rail 10, and the movable frame 20 is configured to be able to move back and forth along the extension direction of the guide rail 10. The lifting arm 30 is rotatably connected to the movable frame 20, and the rotation axis of the lifting arm 30 is perpendicular to the extension direction of the guide rail 10. The connecting structure 40 includes a connecting member 41 and a driving assembly 42. The connecting member 41 is transmission-connected to the driving assembly 42. The driving assembly 42 is installed on the lifting arm 30. The driving assembly 42 is used to drive the connecting member 41 to move back and forth in a direction perpendicular to the extension direction of the guide rail 10.

[0102] For ease of understanding, the following example illustrates the process of placing the IT equipment wall outside the cabinet 200 in the receiving compartment 20a using the immersion liquid cooler hanging mechanism 100:

[0103] When the immersion liquid cooler lifting mechanism 100 is in operation, the movable frame 20 drives the lifting arm 30 to move along the extension direction of the guide rail 10 to a preset position for material removal. The lifting arm 30 then rotates to the upper and outer sides of the cabinet 200. The drive assembly 42 drives the connector 41 to move perpendicularly to the extension direction of the guide rail 10, connecting the connector 41 to the IT equipment 10a outside the cabinet 200. The drive assembly 42 then drives the connector 41 to move perpendicularly to the extension direction of the guide rail 10, moving the IT equipment 10a to the upper and outer sides of the cabinet 200. The lifting arm 30 then rotates, rotating the connector 41 and the IT equipment 10a directly above the cabinet 200. The movable frame 20 then drives the lifting arm 30 to move along the extension direction of the guide rail 10 to a position for placing the IT equipment 10a. Then the driving component 42 drives the connecting member 41 to move in a direction perpendicular to the extension direction of the guide rail 10, allowing the connecting member 41 to drive the IT equipment 10a into the cabinet 200.

[0104] Of course, the immersion liquid chiller hanging mechanism 100 can remove the IT equipment 10a from the cabinet 200 in a similar manner as described above.

[0105] Compared to conventional cranes that move on the ground, the guide rails 10 of the present application can be connected to the rack, and the movable rack 20 is movably connected to the guide rails 10, so that the immersion liquid cooler lifting mechanism 100 can be directly assembled with the cabinet 200, and the lifting arm 30 can be moved relative to the cabinet 200 to complete the loading and unloading of the IT equipment 10a, saving the steps of position adjustment and calibration between the cabinet 200, which is conducive to improving the convenience of operation of the immersion liquid cooler lifting mechanism 100, and also makes the immersion liquid cooler lifting mechanism 100 and the cabinet 200 better matched, thereby helping to improve the efficiency and accuracy of loading and unloading of IT equipment 10a. In addition, compared to conventional cranes that move on the ground, the immersion liquid cooler lifting mechanism 100 of the present application does not need to be placed on the ground, so that the cabinet 200 acts as a supporting structure and there is no need to reserve space for the crane to move, which is conducive to reducing the space occupied by the immersion liquid cooler lifting mechanism 100.

[0106] In some embodiments, see Figure 1 and Figure 2 The extending direction of the guide rail 10 is parallel to the third direction Z, and the direction in which the driving assembly 42 drives the connecting member 41 to reciprocate is parallel to the second direction Y. The driving assembly 42 is used to drive the connecting member 41 to enter and exit the receiving compartment 20a through the opening 20b along the second direction Y and a direction opposite to the second direction Y.

[0107] In some embodiments, see Figure 1 and Figure 2 The guide rail 10 is connected to the first wall 201, so that the guide rail 10 is connected to one side of the cabinet 200 in the first direction X and enters and exits the receiving compartment 20a through the opening 20b along the second direction Y and the direction opposite to the second direction Y via the lifting arm 30. This facilitates the assembly of the immersion liquid cooler lifting mechanism 100 and the cabinet 200 and the completion of the loading and unloading of IT equipment 10a, thereby improving the efficiency and accuracy of loading and unloading IT equipment 10a and reducing the space occupied by the immersion liquid cooler lifting mechanism 100.

[0108] In some embodiments, a bearing is provided between the hoisting arm 30 and the movable frame 20 to achieve a rotational connection between the hoisting arm 30 and the rotating frame.

[0109] In some embodiments, see Figure 2 The connecting member 41 includes a hanging rod 411 and a hook provided on the hanging rod 411. The hanging rod 411 is connected to the connecting line 422, and the IT equipment 10a can be hung on the hook.

[0110] In some embodiments, a plurality of hooks 412 are provided along the hook along the extension direction of the hanging rod 411 , and the plurality of hooks 412 are arranged at intervals, which helps to make the connector 41 suitable for IT equipment 10 a of different sizes.

[0111] In some embodiments, see Figure 3 The immersion liquid refrigerator lifting mechanism 100 also includes a first locking member 50, which is installed on the movable frame 20. The first locking member 50 has a first locking state and a first open state. When the first locking member 50 is in the first locking 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.

[0112] It should be noted that during the transfer of IT equipment 10a by the immersion cooler lifting mechanism 100, when the movable frame 20 and the lifting arm 30 no longer need to be moved, the first locking member 50 can be used to restrict the movement of the movable frame 20, thereby restricting the movement of the lifting arm 30. The first locking member 50 helps reduce the risk of the immersion cooler lifting mechanism 100 shifting the IT equipment 10a during placement in the storage compartment 20a. It also helps the immersion cooler lifting mechanism 100 accurately locate the IT equipment 10a to be transferred, thereby improving the accuracy of the immersion cooler lifting mechanism 100 in loading and unloading IT equipment 10a.

[0113] In some embodiments, see Figure 3 The first locking member 50 includes an operating portion 51, a rotating portion 52 and a contact portion 53 connected in sequence. The operating portion 51 is located on the side of the mobile frame 20 away from the guide rail 10, so that the operating portion 51 is in a larger space on the outside, which is beneficial for the operator to control the operating portion 51 or to connect the operating portion 51 with other drive structures. The rotating portion 52 is rotatably mounted on the mobile frame 20, and the contact portion 53 is located on the side of the mobile frame 20 facing the guide rail 10. The rotating portion 52 is configured to drive the contact portion 53 away from or toward the guide rail 10 when rotating. When the first locking member 50 is in the first locking state, the contact portion 53 contacts the guide rail 10, and when the first locking member 50 is in the first open state, the contact portion 53 is separated from the guide rail 10.

[0114] It is understandable that when the abutment portion 53 abuts the guide rail 10, the friction between the abutment portion 53 and the guide rail 10 prevents the movable frame 20 from continuing to move, thereby limiting the movement of the movable frame 20 and placing the first locking member 50 in the first locked state. When the abutment portion 53 is separated from the guide rail 10, there is no friction between the abutment portion 53 and the guide rail 10, thereby releasing the force that limits the movement of the movable frame 20 and placing the first locking member 50 in the first open state. The above solution allows the movable frame 20 to be locked when it moves to any position on the guide rail 10, thereby achieving stepless adjustment of the fixed position of the movable frame 20 and the hanging arm 30 in the extension direction of the guide rail 10.

[0115] In some embodiments, the rotating portion 52 is threadedly connected to the movable frame 20. For example, the rotating portion 52 can be a rod with an external thread, and the movable frame 20 has a threaded hole adapted to the external thread. The rotating portion 52 is inserted into the threaded hole so that the external thread and the internal thread of the threaded hole match.

[0116] In some embodiments, the abutment portion 53 includes elastic materials such as silicone, rubber, or flexible plastic, which helps to reduce the risk of damage when the abutment portion 53 and the guide rail 10 abut, and also makes it easier to increase the friction between the abutment portion 53 and the guide rail 10.

[0117] In some embodiments, see Figure 3 and Figure 4 The immersion liquid refrigerator lifting mechanism 100 also includes a second locking member 60, which is installed on the movable frame 20. The second locking member 60 has a second locking state and a second open state. When the second locking member 60 is in the second locking state, the second locking member 60 restricts the rotation of the lifting arm 30. When the second locking member 60 is in the second open state, the second locking member 60 releases the restriction on the lifting arm 30.

[0118] It should be noted that when the lifting arm 30 does not need to rotate during the process of transferring IT equipment 10a, the second locking member 60 can be used to limit the rotation of the lifting arm 30. On the one hand, limiting the rotation of the lifting arm 30 when it does not need to rotate is conducive to reducing the possibility of the lifting arm 30 being rotated by external forces or rotating on its own, thereby reducing the risk of the lifting arm 30 colliding with other structures or causing injury to the operator, and improving the safety of the lifting arm 30; on the other hand, when the lifting mechanism 100 of the immersion liquid refrigerator is not transferring IT equipment 10a, the second locking member 60 can be used to fix the angle of the lifting arm 30 at an angle that occupies less space, which is conducive to reducing the risk of the lifting mechanism 100 of the immersion liquid refrigerator. 100 as a whole occupies space; thirdly, the second locking member 60 can suppress the unexpected rotation of the immersion liquid refrigerator lifting mechanism 100 when transferring the IT equipment 10a, thereby helping to reduce the risk of the immersion liquid refrigerator lifting mechanism 100 placing the IT equipment 10a off-center during the process of placing the IT equipment 10a in the storage compartment 20a, and also helping the immersion liquid refrigerator lifting mechanism 100 to accurately obtain the IT equipment 10a to be transferred, thereby helping to improve the accuracy of the immersion liquid refrigerator lifting mechanism 100 in completing the loading and unloading of the IT equipment 10a.

[0119] In some embodiments, see Figure 3 and Figure 4The second locking member 60 includes a locking rod 61 and a moving rod 62. The locking rod 61 is connected to the moving rod 62, and the moving rod 62 is movably connected to the movable frame 20. The hanging arm 30 is provided with a positioning hole 311. When the second locking member 60 is in the second locking state, the locking rod 61 drives the locking rod 61 to extend into the positioning hole 311 to restrict the rotation of the hanging arm 30. When the second locking member 60 is in the second opening state, the locking rod 61 exits the positioning hole 311 to release the restriction on the hanging arm 30. By controlling the movement of the moving rod 62, the rotation of the hanging arm 30 can be restricted, which has the advantages of simple locking method and easy operation.

[0120] In some embodiments, see Figures 3 to 5 The movable frame 20 includes a slider 21 and a support block 22. The slider 21 is slidably connected to the guide rail 10, and the support block 22 is connected to the slider 21. The support block 22 is provided with a guide hole 221. The movable rod 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 sequence. When the second locking member 60 is in the second open state, the movable rod 62 is provided in the first portion 2211. When the second locking member 60 is in the second locked state, the movable rod 62 is provided in the second portion 2212. The first portion 2211 and the third portion 2213 are both provided with elastic clamping members 25, which are used to clamp the movable rod 62.

[0121] The elastic clamping member 25 can exert a damping effect on the movable rod 62, providing a force to maintain the movable rod 62 in the first portion 2211 or the second portion 2212, thereby improving the stability of the second locking member 60 in the second locked state and the second open state. Furthermore, the absence of the elastic clamping member 25 in the second portion 2212 helps reduce the ease with which the movable rod 62 can enter the second portion 2212 from the first portion 2211 or from the third portion 2213. The absence of the elastic clamping member 25 in the second portion 2212 also allows the movable rod 62 to transition from an undamped state to an impacted state when entering the first portion 2211 or the third portion 2213. This makes it easier for an operator to determine whether the movable rod 62 has entered the first portion 2211 or the second portion 2212, and therefore, whether the second locking member 60 is in the second locked state or the second open state.

[0122] In some embodiments, the elastic clamping member 25 may be formed by curling a metal spring sheet, or the elastic clamping member 25 may be a spring or other structure, which is not specifically limited here.

[0123] In some embodiments, see Figure 4The movable frame 20 further includes two fixed plates 23 arranged along the second direction Y, and the lifting arm 30 is rotationally connected to the two fixed plates 23.

[0124] For example, the lifting arms 30 are rotatably connected to the two fixing plates 23 via bearings.

[0125] In some embodiments, the movable frame 20 further includes a cover plate 24 , on which captive screws are provided. The cover plate 24 is connected to the two fixing plates 23 via the captive screws.

[0126] In some embodiments, see Figure 4 and Figure 5 The guide rail 10 is provided with a material-retrieving position 11 and a non-retrieving position 12. The material-retrieving position 11 of the guide rail 10 is provided with an avoidance hole 111. The avoidance hole 111 is used to accommodate part of the locking rod 61. When the movable frame 20 is in the non-retrieving position 12, the guide rail 10 blocks one end of the locking rod 61 away from the positioning hole 311, so that the locking rod 61 cannot be withdrawn from the positioning hole 311, thereby preventing the hanging arm 30 from rotating when the movable frame 20 is in the non-retrieving position 12. When the movable frame 20 is in the material-retrieving position 11, the locking rod 61 can partially extend into the avoidance hole 111, so that the locking rod 61 can withdraw from the positioning hole 311, thereby allowing the hanging arm 30 to rotate when the movable frame 20 is in the material-retrieving position 11. Such a setting can limit the lifting arm 30 to rotate only at the material picking position 11 and then rotate to the top of the opening 20b, reducing the risk of the lifting arm 30 rotating at the non-material picking position 12 and causing the lifting arm 30 to collide with other structures or cause injury to the operator, thereby improving the safety of the lifting arm 30.

[0127] In some embodiments, the shape of the avoidance hole 111 is adapted to the locking rod 61, so that when the locking rod 61 extends into the avoidance hole 111, it can restrict the movement of the movable rack 20. This configuration, on the one hand, helps reduce the possibility of the lifting arm 30 being moved by external forces, thereby reducing the risk of the lifting arm 30 colliding with other structures or causing injury to the operator, thereby improving the safety of the lifting arm 30. It also helps reduce the risk of the immersion liquid cooler lifting mechanism 100 shaking when acquiring the IT equipment 10a, and reduces the risk of the IT equipment 10a being placed off-center during placement in the storage compartment 20a.

[0128] In some embodiments, see Figure 4 and Figure 5The immersion liquid refrigerator lifting mechanism 100 further includes a locking mechanism 90, which includes a connecting plate 91, a first clamping arm 92, a second clamping arm 93, and a tensioning member 94. The connecting plate 91 is connected to the fixed plate 23, and the first clamping arm 92 and the second clamping arm 93 are connected to the connecting plate 91. The first clamping arm 92 and the second clamping arm 93 clamp the lifting arm 30. The tensioning member 94 is disposed through the first clamping arm 92 and connected to the second clamping arm 93. The tensioning member 94 can rotate relative to the first clamping arm 92 and drive the second clamping arm 93 to move toward and away from the first clamping arm 92, so that the first clamping arm 92 and the second clamping arm 93 can clamp the lifting arm 30 to limit the rotation of the lifting arm 30. The tensioning member 94 can also enable the first clamping arm 92 and the second clamping arm 93 to loosen or reduce the clamping force on the lifting arm 30 to allow the lifting arm 30 to rotate.

[0129] Understandably, with reference to Figure 4 and Figure 5 When the movable rack 20 is in the material-retrieving position 11, the locking rod 61 can extend into the avoidance hole 111 and limit the movement of the movable rack 20. Then, by rotating the tensioning member 94, the first clamping arm 92 and the second clamping arm 93 can clamp the lifting arm 30 to limit the rotation of the lifting arm 30, thereby improving the stability, accuracy and safety of the lifting arm 30 in lifting the IT equipment 10a.

[0130] In some embodiments, the tensioning member 94 may be a combination of a bolt and a handle. The first clamping arm 92 is provided with a through hole for the tensioning member 94 to pass through, and the second clamping arm 93 is provided with a threaded hole connected to the tensioning member 94 .

[0131] In some embodiments, see Figure 2 The hanging arm 30 includes a first arm 31 and a second arm 32. The first arm 31 is rotatably connected to the mobile frame 20. The first arm 31 is connected to the second arm 32. The second arm 32 extends perpendicularly to the first arm 31. A clearance space 33 is defined between the second arm 32 and the first arm 31. The connector 41 is located in the clearance space 33. The clearance space 33 facilitates accommodating the IT equipment 10a and providing space for movement of the IT equipment 10a.

[0132] In some embodiments, see Figure 2 , the extending direction of the first arm 31 is parallel to the second direction Y.

[0133] In some embodiments, the first arm 31 may include one section of rod or multiple sections of rods connected in sequence, and the second arm 32 may include one section of rod or multiple sections of rods connected in sequence, which are not specifically limited here.

[0134] In some embodiments, see Figure 2Along the first direction X, the material picking position 11 of the guide rail 10 is located at one end of the guide rail 10, which is conducive to providing space for accommodating the second arm 32, so that the second arm 32 does not exceed the edge of the guide rail 10 in the first direction X when rotating, thereby helping to reduce the overall occupied space of the immersion liquid refrigerator lifting mechanism 100.

[0135] In some embodiments, see Figure 2 The driving assembly 42 includes a winch 421 and a connecting line 422. The winch 421 is installed on the lifting arm 30. The winch 421 is connected to the connecting line 422. The connecting line 422 is passed through the second arm 32 and partially extends into the avoidance space 33. The connecting line 422 is connected to the connector 41. The winch 421 is configured to drive the connecting line 422 when it rotates, so as to drive the connector 41 to move back and forth in a direction perpendicular to the extension direction of the guide rail 10. By rotating the winch 421, the length of the connecting line 422 in the avoidance space 33 can be adjusted, and then the connector 41 can be driven to move back and forth in a direction perpendicular to the extension direction of the guide rail 10. Compared with driving methods such as linear motors, pneumatic cylinders and hydraulic cylinders, the driving method of the winch 421 and the connecting line 422 has the advantages of simple structure, small space occupation, low weight, easy maintenance and low cost.

[0136] In some embodiments, see Figure 2 The avoidance space 33 has a first side (unlabeled) and a second side (unlabeled) that are opposite to each other. The first and second sides are perpendicular to each other, as are the extension directions of the second arm 32 and the first arm 31. The immersion liquid refrigerator hanging mechanism 100 also includes a first reinforcement member 70 and a second reinforcement member 80. The first reinforcement member 70 is provided on the first side and is connected to both the first arm 31 and the second arm 32. The second reinforcement member 80 is provided on the second side and is connected to both the first arm 31 and the second arm 32.

[0137] The first reinforcement member 70 and the second reinforcement member 80 help improve the stability of the connection between the first arm 31 and the second arm 32, thereby increasing the load capacity of the suspension arm 30. Furthermore, by positioning the first reinforcement member 70 on the first side and the second reinforcement member 80 on the second side, the first reinforcement member 70 and the second reinforcement member 80 do not occupy the avoidance space 33, allowing the connector 41 and the IT equipment 10a to be at least partially located between the first reinforcement member 70 and the second reinforcement member 80. This makes the immersion liquid cooler suspension mechanism 100 more compact and occupies less space.

[0138] In some embodiments, the first reinforcement member 70 and the second reinforcement member 80 may be triangular reinforcement structures.

[0139] In addition, those skilled in the art should recognize that the above embodiments are merely intended to illustrate the present application and are not intended to limit the present application. As long as they are within the substantive scope of the present application, appropriate changes and modifications to the above embodiments are within the scope disclosed in the present application.
