Description

Technical Field

[0001] The invention relates to the technical field of emergency power supply, and in particular to a lifting power supply device. Background Art

[0002] At present, as the core infrastructure of information technology, the data center room carries a large number of servers and key businesses, and its stability and reliability are crucial. In the actual operation process, the power module in the room often fails, causing the upper power switch of the server to trip, the PDU strip of the entire circuit to lose power, and the server enters a single-circuit power supply state, which undoubtedly poses a direct threat to the operation safety of the server. In the face of such emergencies, operation and maintenance personnel need to take emergency measures quickly to restore the dual-circuit power supply of the server to ensure business continuity and data security. When emergency repair of a single-circuit power failure of the server, operation and maintenance personnel usually use traditional cable trays to provide temporary power. Since the length of the power cord in the data center server cabinet has been preset and fixed to adapt to the specific cabinet structure and power supply position, this means that there are differences in the length of the power cord between servers at different heights. During emergency power supply, the cable tray needs to be placed in a position that matches the height of the server power cord to ensure that the power cord can be smoothly connected to the server without causing additional stress or damage. When the operation and maintenance personnel are handling a single-circuit power failure of a server, if the faulty server is located at a high position, they need to raise the cable tray to the corresponding height to ensure that the power cord can be smoothly connected; if the faulty server is located at a low position, they need to lower the cable tray to match the height of the server.

[0003] However, this method of manually lifting and supporting the cable tray is not only laborious and inefficient, but more importantly, the long-term manual support of the power supply device not only increases the physical burden of the operation and maintenance personnel, but also brings safety hazards, because any operational errors may cause damage to the server power cord, thereby affecting the stable operation of the server. In addition, the height and stability of the manually supported cable tray are difficult to guarantee, especially when operations need to be performed at high altitudes, it is more likely to cause safety accidents due to instability. Therefore, the emergency power supply method in the prior art has obvious deficiencies in reliability, safety and ease of operation, and a more effective and safer emergency power supply solution is urgently needed.

[0023] It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of the present application can be combined with each other. The present invention will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0024] It should be noted that, unless otherwise specified, all technical and scientific terms used in this application have the same meanings as commonly understood by ordinary technicians in the technical field to which this application belongs.

[0025] In the present invention, unless otherwise specified, the directional words used, such as "up, down, top, bottom", usually refer to the directions shown in the drawings, or to the components themselves in the vertical, perpendicular or gravity directions; similarly, for ease of understanding and description, "inside and outside" refer to the inside and outside relative to the outline of each component itself, but the above-mentioned directional words are not used to limit the present invention.

[0026] like Figures 1 to 4 As shown, an embodiment of the present invention provides a lifting power supply device, including a base plate 4; a plurality of guide wheels 5, which are installed at the bottom of the base plate 4; a fixed plate 1, which is located above the base plate 4 and spaced apart from the base plate 4; a telescopic rod 3, the two ends of the telescopic rod 3 are respectively connected to the fixed plate 1 and the base plate 4, and the telescopic rod 3 is telescopically arranged; a column 6, which extends in the vertical direction, and the column 6 is provided with a plurality of clamping parts 8 distributed in the vertical direction, and a positioning assembly 7 is provided on the fixed plate 1, and the positioning assembly 7 is matched with the plurality of clamping parts 8 to be clamped with one of the plurality of clamping parts 8; a cable reel 2, and the cable reel 2 is rotatably arranged on the fixed plate 1 to wind or release the cable.

[0027] The lifting power supply device provided in the embodiment of the present invention provides an emergency power supply solution that can adapt to different server heights without manual support through the coordinated action of the height-adjustable telescopic rod 3, the automatically locking positioning component 7, the rotating cable reel 2 and the movable and stable guide wheel 5, thereby solving the technical problem in the prior art that the power supply device needs to be manually supported during maintenance due to the different server heights.

[0028] In the above embodiment, the bottom plate 4 serves as the load-bearing and basic platform of the entire device, while the guide wheel 5 gives the device flexibility to move. The fixed plate 1 serves as a platform for carrying the cable reel 2 and the positioning assembly 7, and can move up and down through the connection with the telescopic rod 3. The cable reel 2 is arranged on the fixed plate 1, and its rotation function facilitates the orderly management and quick connection of the cable, and can ensure the smooth release and recovery of the cable no matter what height the fixed plate 1 is at. The two ends of the telescopic rod 3 are respectively connected to the fixed plate 1 and the bottom plate 4, and its telescopic function cooperates with the clamping part 8 on the column 6 and the positioning assembly 7 on the fixed plate 1, so that the fixed plate 1 can be positioned between multiple preset heights along the clamping part 8 on the column 6, realizing the precise adjustment of the height of the cable reel 2 without the need for manual continuous lifting. The positioning rod 72 in the positioning assembly 7 is clamped with the clamping part 8 on the column 6, ensuring the stability of the fixed plate 1 when it is telescoped to the required height.

[0029] The above design, through the cooperation of the telescopic rod 3 and the positioning assembly 7, allows the device to quickly and automatically adjust to a height that matches the server power cord, eliminating the inconvenience of manual lifting and greatly improving the efficiency of maintenance and emergency response. The automatic clamping mechanism of the positioning assembly 7 and the clamping part 8 ensures the safe locking of the device during the height adjustment process, prevents the device from being unstable or slipping due to manual operation errors, and reduces the safety risks during maintenance. The rotation function of the cable reel 2 and the height adjustment of the telescopic rod 3 are combined to allow the cable to be released accurately as needed, reducing the risk of cable clutter and damage, while improving the accuracy and speed of power cord connection.

[0030] Specifically, the lifting power supply device is provided with a plurality of telescopic rods 3 and a plurality of columns 6, wherein the plurality of telescopic rods 3 are arranged at intervals on one side of the bottom plate 4, and the plurality of columns 6 are arranged on the other side of the bottom plate 4 corresponding to the plurality of telescopic rods 3, and the heights of the telescopic rods 3 and the columns 6 are arranged correspondingly. The telescopic rod 3 is fixed on one side of the bottom plate 4, and its design can be telescopic. The bottom plate 4 serves as the bottom support of the entire device, ensuring the stable installation of the telescopic rod 3 and the stability of the entire device. The telescopic function of the telescopic rod 3, in conjunction with the up and down movement of the fixed plate 1, enables the cable reel 2 to be adjusted to a height matching the server power cord. This design ensures that even when facing servers of different heights, the cable reel 2 can automatically adjust to a suitable position, without the need for additional manual lifting or lifting of the power supply device, significantly improving the convenience and efficiency of operation. The column 6 is fixed on the other side of the bottom plate 4 and is arranged opposite to the telescopic rod 3. The vertical extension of the column 6 provides a guide reference for height adjustment. The plurality of clamping parts 8 on the column 6 are distributed in the vertical direction, and cooperate with the positioning assembly 7 on the fixed plate 1 to form a height locking mechanism. When the telescopic rod 3 drives the fixed plate 1 to move, the positioning assembly 7 can be positioned in the clamping portion 8 of the column 6, ensuring that the fixed plate 1 can be stably fixed after reaching the required height. The spacing between the telescopic rod 3 and the column 6 on both sides of the bottom plate 4, as well as the corresponding height setting between them, jointly ensure the balance and stability of the entire device during the telescopic process. The telescopic rod 3 not only realizes the vertical movement of the fixed plate 1, but the clamping portion 8 on the column 6 also cooperates with the positioning assembly 7 on the fixed plate 1 to provide precise height positioning and locking functions, ensuring that the device can work stably at any height without the need for continuous manual support.

[0031] Specifically, the positioning assembly 7 includes a positioning box body 71, which is surrounded by side walls to form a receiving cavity; a positioning rod 72, which is movably arranged on the positioning box body 71, and one end of the positioning rod 72 close to the clamping portion 8 is extended or retracted relative to the positioning box body 71 to be clamped or separated with the clamping portion 8. The positioning box body 71 is formed by the side walls, and the internal receiving cavity is used to accommodate the positioning rod 72 and related control and transmission mechanisms. The positioning box body 71 not only provides a track for the positioning rod 72 to be installed and moved, but also provides structural support for the entire positioning assembly 7. The positioning rod 72 is movably arranged on the positioning box body 71, and its design allows one end to be extended or retracted relative to the positioning box body 71, and to be clamped or separated with the clamping portion 8 on the column 6. This design allows the positioning rod 72 to be automatically or manually engaged with the clamping portion 8 as needed when the fixed plate 1 rises or falls, thereby fixing the fixed plate 1 at any preset height. The extension or retraction of the positioning rod 72 cooperates with the clamping portion 8 on the column 6 to ensure that the fixing plate 1 can be accurately clamped when it moves to a specific height along the column 6. The distribution of the clamping portion 8 is along the vertical direction of the column 6, which is consistent with the movement path of the positioning rod 72, which means that when the positioning rod 72 is extended to a position aligned with the clamping portion 8, it can be automatically or under the control of the operator to clamp with the clamping portion 8, thereby positioning the fixing plate 1 at a desired height, realizing the height adjustability of the device.

[0032] Specifically, the positioning assembly 7 also includes a positioning lever 73, one end of which is connected to the positioning rod 72, and an opening 77 is provided on the side wall. The other end of the positioning lever 73 extends out of the opening 77, and the positioning lever 73 is movably provided relative to the opening 77 to drive the positioning rod 72 to engage or separate relative to the clamping portion 8. The positioning lever 73 is designed to control the movement of the positioning lever 72. When it is necessary to adjust the height of the fixed plate 1, the operator can control the separation of the positioning rod 72 and the clamping portion 8 through the positioning lever 73, thereby allowing the fixed plate 1 to move up and down along the column 6. After the fixed plate 1 reaches a new height, the positioning lever 73 can control the positioning rod 72 to extend into the clamping portion 8 again to achieve a new height positioning. This design makes the height adjustment process more controllable and safe.

[0033] Specifically, the positioning assembly 7 further includes a spring 74, one end of which is connected to the positioning lever 73, and the other end of which is connected to the positioning box body 71. The spring 74 provides a driving force for the positioning rod 72 to maintain the engagement with the clamping portion 8. The spring 74 is arranged in the accommodating cavity of the positioning box body 71 and is connected to the positioning rod 72. When the positioning rod 72 is engaged with the clamping portion 8, the elastic force provided by the spring 74 helps to maintain the close contact between the positioning rod 72 and the clamping portion 8, thereby enhancing the reliability of the engagement. When the positioning rod 72 is released to separate it from the clamping portion 8, the spring 74 can be compressed. When the pressure is released, the spring 74 pushes the positioning rod 72 back to the initial position, ready for the next engagement. This design makes the operation of the positioning assembly 7 more automated and convenient.

[0034] Specifically, the positioning assembly 7 further includes a first mounting rod 75 and a second mounting rod 76. The first mounting rod 75 is arranged on the positioning box body 71 perpendicular to the positioning rod 72, and the second mounting rod 76 is arranged on the side of the positioning rod 72 close to the first mounting rod 75. The first mounting rod 75 and the second mounting rod 76 are arranged in parallel. The two ends of the spring 74 are connected to the first mounting rod 75 and the second mounting rod 76 respectively. When the positioning rod 72 is engaged with the clamping portion 8, the spring 74 is in a stretched state. The first mounting rod 75 is arranged on the positioning box body 71 perpendicular to the positioning rod 72, and the second mounting rod 76 is arranged on the side of the positioning rod 72 close to the first mounting rod 75. The two mounting rods are parallel and fixed. This design ensures that the spring 74 can move smoothly along the axis defined by the first mounting rod 75 and the second mounting rod 76 when stretched or compressed, avoids the spring 74 from being deflected or twisted during the movement, ensures that the spring 74 can effectively keep the positioning rod 72 in the clamping state or make it easily disengage from the clamping portion 8, and enhances the stability and reliability of the entire locking and unlocking process.

[0035] Specifically, the clamping portion 8 is a groove, and the end of the positioning rod 7 extends into the groove to engage with the column 6. The positioning lever 73 is used as an interactive tool between the operator and the positioning assembly 7, and one end of the positioning lever is designed to be retractable, so as to achieve the clamping or separation with the clamping portion 8 (groove) on the column 6. When the fixed plate 1 rises to the required height, the positioning rod 72 engages with the clamping portion 8, and the end of the positioning lever 73 extends into the adjacent clamping portion 8 (groove), further enhancing the stability of the positioning. This design ensures that even under the action of unexpected external forces, the fixed plate 1 can be maintained at the set height without accidental movement or decline.

[0036] Specifically, a plurality of protrusions 62 are provided on the column 6, and a groove is formed between two adjacent protrusions 62. The protrusions 62 are arranged on the surface of the column 6 and are spaced apart along the length direction of the column 6. A groove is formed between each protrusion 62 and its adjacent protrusion, and these grooves constitute optional height positioning points of the fixing plate 1 in the vertical direction. This design ensures that the fixing plate 1 can be positioned at multiple preset height positions on the column 6 to meet the height requirements of different servers. The positioning rod 72 is a key component in the positioning assembly 7 responsible for engaging or disengaging with the clamping portion (here, the clamping portion is composed of the protrusion 62) on the column 6. When the fixing plate 1 is driven to rise or fall by the telescopic rod 3, one end of the positioning rod 72 will contact the protrusion 62 on the column 6 until it reaches the corresponding groove position. At this time, the positioning rod 72 automatically extends and snaps into the groove under the action of the spring 74, forming a stable mechanical lock, thereby fixing the fixing plate 1 at this height.

[0037] Specifically, each protrusion 62 is provided with an inclined surface, and the distance between the inclined surface and the column 6 gradually increases in the direction away from the bottom plate 4, and the end of the positioning rod 72 close to the clamping portion 8 is inclined corresponding to the inclined surface. The protrusion 62 is arranged on the column 6 and distributed along the vertical direction of the column 6. The inclined surface arranged thereon has a key characteristic: the distance between the inclined surface and the column 6 gradually increases in the direction away from the bottom plate 4. The purpose of this inclined surface design is to enable the positioning rod 72 to smoothly contact the inclined surface of the protrusion 62 and gradually move along the inclined surface when the telescopic rod 3 drives the fixed plate 1 to rise or fall, thereby realizing the automatic clamping or separation of the positioning rod 72 and the clamping portion 8. The end of the positioning assembly 7 close to the clamping portion 8 is designed to be inclined corresponding to the inclined surface on the protrusion 62. When the fixed plate 1 moves upward, the inclined end of the positioning rod 72 first contacts the inclined surface of the protrusion 62, and the gradually increasing distance of the inclined surface guides the positioning rod 72 to automatically extend and clamp into the clamping portion 8, so as to realize the locking of the fixed plate 1 at this height. On the contrary, when the fixing plate 1 moves downward, the positioning rod 72 gradually separates along the inclined surface of the protrusion 62 and finally completely disengages from the clamping portion 8, so that the fixing plate 1 can freely descend.

[0038] Specifically, the telescopic rod 3 includes a first set of rods 31, a second set of rods 32 and a third set of rods 33 which are sequentially sleeved; two handles 11 are arranged above the fixed plate 1; a handrail 61 is arranged at the top of the column 6, and the handrail 61 is extended in the horizontal direction; the guide wheel 5 is provided with a brake, and a rotating handle 22 is arranged at the axis of at least one end of the cable reel 2, and the rotating end of the rotating handle 22 is eccentrically arranged relative to the axis. The telescopic rod 3 is composed of the first set of rods 31, the second set of rods 32 and the third set of rods 33 which are sleeved in sequence. This multi-stage telescopic design allows the cable reel 2 on the fixed plate 1 to be able to adjust the height over a wide range. The first set of rods 31 is fixed to the bottom plate 4, and the second set of rods 32 and the third set of rods 33 are sleeved in the first set of rods 31 in sequence to form a telescopic structure. When the height of the fixed plate 1 needs to be adjusted, the operator can drive the fixed plate 1 to move up and down by controlling the extension and contraction of the third set of rods 33, and the cooperation of the second set of rods 32 and the third set of rods 33 ensures the stability and positioning accuracy during the movement. The handle 11 is arranged above the fixed plate 1, so that the operator can directly lift the fixed plate 1 when necessary to perform manual height adjustment or quick adjustment in an emergency. The handrail 61 on the top of the column 6 extends in the horizontal direction, providing a stable operating support point for the operator. In particular, when the height of the entire device needs to be adjusted or moved, the handrail 61 can serve as a stable support to help the operator better control and operate the device, thereby improving the safety and comfort of operation. The guide wheel 5 is provided with a brake component. This design enables the operator to quickly lock the wheel when necessary to prevent the device from accidentally moving during height adjustment or use. In particular, in the case of narrow space and dense equipment in the computer room of the data center, the use of brake components can greatly improve the stability and safety of the device. In addition, the provision of the brake component also enables the operator to park the device firmly when not in use, which is convenient for storage and management. A rotating handle 22 is provided at the axis of at least one end of the cable reel 2, and the rotating end of the rotating handle 22 is eccentrically arranged relative to the axis. This design allows the operator to control the rotation of the cable reel 2 by rotating the rotating handle 22, thereby conveniently winding in or releasing the cable without directly contacting the cable, thereby improving the convenience and safety of operation. The eccentric setting of the rotating handle 22 can also increase the torque during rotation, so that even if the cable is long or heavy, the operator can easily control the rotation of the cable reel 2, avoiding the effort and inconvenience in the cable management process.

[0039] In the above embodiment, Figure 1 , Figure 2The three-dimensional structure diagram of a new type of lifting power supply device is shown, which mainly includes a base plate 4, and a plurality of guide wheels 5 are installed at the bottom of the base plate 4. These guide wheels 5 are equipped with brakes to ensure the stability of the device when it is stationary. The fixed plate 1 is located above the base plate 4, spaced apart from the base plate 4, and connected to the base plate 4 through a plurality of telescopic rods 3. One end of the telescopic rod 3 is connected to the fixed plate 1, and the other end is fixed to the base plate 4. Its structure includes a first set of rods 31, a second set of rods 32, and a third set of rods 33 that are sequentially connected. This design enables the telescopic rods 3 to be extended and retracted as needed, thereby adjusting the overall height of the power supply device to adapt to different workplaces and work requirements.

[0040] Figure 3 The structure of the positioning assembly 7 is shown in detail. The positioning assembly 7 includes a positioning box body 71. The interior of the positioning box body 71 is enclosed to form a receiving cavity. The positioning rod 72 is movably arranged on the positioning box body 71. One end of the positioning rod 72 is designed to be engaged with or separated from the clamping portion 8, and the other end is connected to the positioning lever 73. The positioning lever 73 extends out of one side of the positioning box body 71. Through the relative movement of the positioning box body 71, the positioning rod 72 can be driven to engage with or separate from the clamping portion 8. The opening 77 provided on the side wall allows the extended end of the positioning lever 73 to be easily touched by the operator. In addition, one end of the spring 74 is connected to the positioning lever 73, and the other end is connected to the positioning box body 71, providing a driving force for the positioning rod 72 to maintain engagement with the clamping portion 8, ensuring that the positioning rod 72 can stably maintain engagement with the clamping portion 8 without human intervention, thereby fixing the height of the power supply device.

[0041] Figure 4 The details of the column 6 are shown. The column 6 extends in the vertical direction and is provided with a plurality of clamping parts 8 distributed in the vertical direction. These clamping parts 8 are shown as grooves in this embodiment. The column 6 is also provided with a plurality of protrusions 62, and a groove, i.e., the clamping part 8, is naturally formed between two adjacent protrusions 62. Each protrusion 62 is provided with an inclined surface, and the spacing between the inclined surface and the column 6 gradually increases in the direction away from the bottom plate 4. This design is conducive to the positioning rod 72 being able to smoothly enter or exit the clamping part 8 when the telescopic rod 3 is extended and retracted. At the same time, the inclined surface cooperates with the inclination angle of the positioning rod 72 to ensure a smooth transition of the device when adjusting the height, avoiding jamming or excessive wear.

[0042] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0043] Improved operational convenience: The device can automatically adjust to the appropriate position according to the different heights of the server, avoiding the inconvenience of operation and maintenance personnel having to manually support the power supply device, thereby improving emergency repair efficiency and operator experience.

[0044] Enhanced safety: The snap-in function of the positioning component and the driving force provided by the spring ensure the stability of the device at the set height, reducing the potential safety hazards caused by manual operation. The setting of the brake also enhances the stability of the guide wheel and prevents sliding.

[0045] Improved flexibility: The multi-level design of the telescopic rod and the rotation function of the cable reel enable the device to work at a variety of heights without affecting the management and use of cables, adapting to the diverse server layouts in the data center room.

[0046] Optimized cable management: The cable reel’s rotation controls the winding and releasing of cables, avoiding cable clutter and reducing the risk of cable damage. It also facilitates quick connection and removal, improving emergency response speed.

[0047] Enhanced humanized design: The setting of handles and armrests makes it easier for operators to move and control the device, reduces physical burden, makes operation more labor-saving, and reflects the care for operators and the emphasis on practicality.

[0048] To sum up, the lifting power supply device of the present invention provides an emergency power supply solution that is highly adjustable, safe, reliable, and easy to operate through its unique structural design, which significantly improves the deficiencies in the prior art and improves the efficiency and safety of data center computer room operation and maintenance.
