Description

Technical Field

[0001] This invention relates to a windbreak module and its usage method. Background Technology

[0002] Data center cooling utilizes airflow wall modules, which are prefabricated in the factory and integrate multiple devices into a single module. To facilitate unified drainage from the devices (such as air conditioners) within the airflow wall module, a water collection tank is installed on the module's base plate. This allows drainage from the devices within the module to be first collected in the tank before being discharged externally. However, in data center settings, sometimes two or more airflow wall modules need to be sequentially connected. But the water collection tanks of these modules cannot be directly connected to create a single, unified collection tank for all modules. This prevents the drainage from all devices within the airflow wall modules from being channeled into the same tank, hindering the centralized drainage system. Summary of the Invention

[0003] To address the shortcomings of existing technologies, this invention provides a windbreak module, comprising: a flat base plate extending in a front-to-back direction; a through groove (open at both ends of the through groove) formed on the top surface of the base plate and extending in a front-to-back direction; a strip of waterproof sheet laid in a front-to-back direction on the wall of the through groove (the wall of the through groove includes a bottom wall extending in a front-to-back direction and a pair of side walls disposed on the left and right sides of the bottom wall); a reserved amount of retractable material (the reserved amount of retractable material is the waterproof sheet in a retracted state and not laid) pre-reserved at the front end of the waterproof sheet; and a pair of end-opening and closing mechanisms disposed at the front and rear ends of the through groove, capable of closing and opening the ends of the through groove; the reserved amount of retractable material is located in front of the pair of end-opening and closing mechanisms.

[0004] Preferably, the groove end opening and closing mechanism includes: a vertical sealing plate that is perpendicular to the extension direction of the through groove, adapted to the cross-sectional shape of the through groove, pressed onto the waterproof sheet, and forms a sealing fit with the waterproof sheet; and a lifting mechanism that drives the sealing plate to rise and fall.

[0005] Preferably, the cross-sectional shape of the channel is an inverted isosceles trapezoid (the cross-section is perpendicular to the extension direction of the channel, the bottom wall of the channel is flat, and a pair of side walls of the channel are obliquely arranged and symmetrically arranged); the sealing plate is an inverted isosceles trapezoid, and the sealing plate includes: a pair of oblique sides arranged symmetrically on the left and right, and an upper wide side and a lower narrow side located between the pair of oblique sides and arranged vertically; the lower narrow side and the pair of oblique sides of the sealing plate are covered with a leak-proof edging, and the lower narrow side and the pair of oblique sides are pressed against the waterproof sheet of the bottom wall of the channel and the pair of side walls of the channel, and form a sealing fit with the waterproof sheet.

[0006] Preferably, the lifting mechanism includes: a horizontal bar located directly above the sealing plate and spanning the through groove in the left-right direction; a vertical bar fixed to the bottom end of the horizontal bar and the wide edge of the sealing plate; a pair of vertical guide posts located on the left and right sides of the horizontal bar and fixed to the top surface of the base plate at their bottom ends; a pair of vertical sliding sleeves (the sliding sleeves slide vertically with the corresponding guide posts) fixed to the left and right ends of the horizontal bar respectively, corresponding one-to-one with the pair of guide posts; a vertical screw rod (the horizontal bar has a vertical threaded through hole that mates with the screw rod) located on the left or right side of the through groove, close to the guide post on the same side, penetrating the horizontal bar and threadedly engaged with the horizontal bar; a throttle handle located at the top of the screw rod; and a flat bearing (the inner ring of the bearing is fixedly fitted on the screw rod, and the outer ring of the bearing is fixedly connected to the top of the guide post on the same side) rotatably connecting the top of the screw rod to the top of the guide post on the same side.

[0007] Preferably, the lifting mechanism further includes a locking mechanism for locking the crossbar and the screw to prevent the crossbar from rising or falling.

[0008] Preferably, the locking mechanism includes an upper nut and a lower nut disposed on the screw and located on the upper and lower sides of the crossbar to clamp the crossbar.

[0009] Preferably, the front ends of a pair of groove sidewalls of the through groove are respectively provided with: placement grooves for inserting the end of the reserved rewinding material; the left and right ends of the reserved rewinding material are respectively inserted into the placement grooves of a pair of groove sidewalls.

[0010] Preferably, the waterproof sheet and the reserved roll-up material can be laid using a hot-melt method.

[0011] This invention also provides a method for using the above-mentioned wind wall module, including: A single air wall module can be used alone, or two or more air wall modules can be connected together in sequence. When using the air wall module, the drainage from the equipment in each air wall module should be discharged into the same water collection tank, and then the water in the water collection tank should be discharged outwards. Specifically: When a wind wall module is used alone, the front and rear ends of the through slot of the wind wall module are sealed by a pair of sealing plates (the pair of sealing plates at the front and rear ends of the through slot remain closed and do not move), and the through slot with the front and rear ends sealed is used as a water collection tank; when the water collection tank is in use, the liquid level in the water collection tank must be lower than the upper wide edge of the pair of sealing plates at both ends of the through slot (the liquid level in the water collection tank must also be lower than the top surface of the bottom plate) to prevent the water in the water collection tank from overflowing. When two or more wind wall modules are used together in sequence, first, the end slots of each wind wall module are joined together to form a splicing channel. Then, the splicing channel is made to be open at the joint. Then, by rewinding the material with a reserved allowance, the splicing channel is made to form a leak-proof connection at the joint. The front and rear ends of the splicing channel are sealed by a pair of sealing plates. The splicing channel with the open joint and leak-proof connection and the sealed front and rear ends serves as a water collection tank. When using the water collection tank, the liquid level in the water collection tank should be lower than the upper wide edge of the pair of sealing plates at both ends of the splicing channel (the liquid level in the water collection tank should also be lower than the top surface of the bottom plate) to prevent the water in the water collection tank from overflowing.

[0012] Preferably, when the through slots of each wind wall module are connected end to end to form a splicing through slot: the rear end of the through slot of the previous wind wall module is connected to the front end of the through slot of the next wind wall module. When the splicing channel is connected at the joint: the pair of sealing plates located at the joint (i.e., the pair of sealing plates located on the front and rear sides of the joint and closest to the joint) are driven upward by the corresponding lifting mechanism to be completely higher than the top surface of the base plate, so that the splicing channel is connected at the joint; and the sealing plates at the non-joint joint remain stationary (i.e., the pair of sealing plates located at the front and rear ends of the splicing channel remain closed), so that the front and rear ends of the splicing channel are closed by the pair of sealing plates; more specifically, when the sealing plates are driven upward by the corresponding lifting mechanism to be completely higher than the top surface of the base plate: first, rotate the upper nut upward to be close to the bearing, and then rotate the screw through the throttle to drive the crossbar upward. The crossbar drives the sealing plate upward through the vertical rod until the sealing plate is completely higher than the top surface of the base plate (i.e., the lower narrow edge of the sealing plate is higher than the top surface of the base plate). Then, rotate the upper nut downward and rotate the lower nut upward until the upper nut and lower nut clamp the crossbar to lock the crossbar with the screw and prevent the crossbar from rising or falling; When using a pre-reserved allowance of rewind material to create a leak-proof connection at the joint of the splicing channel: the pre-reserved allowance of rewind material from the subsequent wind wall module is removed from the placement slot, and then the pre-reserved allowance of rewind material is rolled forward and laid on the channel wall of the preceding wind wall module (including the bottom wall and a pair of side walls on the left and right sides of the bottom wall) using a hot-melt method; when laying using the hot-melt method, the waterproof sheet rolled forward from the pre-reserved allowance of rewind material crosses the joint and overlaps the waterproof sheet already laid at the rear end of the channel wall of the preceding wind wall module; and the two layers of waterproof sheet are bonded together by the hot-melt method, so that the splicing channel forms a leak-proof connection at the joint.

[0013] The advantages and beneficial effects of the present invention are as follows: It provides a wind wall module and its usage method. The wind wall module of the present invention can be used individually or in combination. When used individually or in combination, it can form a water collection tank. In particular, it can combine two or more wind wall modules to form a unified water collection tank, so that the drainage of the equipment in each wind wall module is first discharged into the same water collection tank, and then the water in the water collection tank is discharged outward.

[0014] The present invention also has the following characteristics: 1) When a wind wall module is used alone, the pair of sealing plates at the front and rear ends of the through groove of the wind wall module remain closed and do not move. The front and rear ends of the through groove are closed by the pair of sealing plates, and the through groove with the front and rear ends closed can be directly used as a water collection tank. That is, any wind wall module of the present invention has a water collection tank directly when it leaves the factory. When a wind wall module is used alone, there is no need to form a water collection tank through additional operations.

[0015] 2) When two or more wind wall modules are spliced ​​together in sequence, the end slots of each wind wall module are first joined together to form a splicing channel. Then, the splicing channel is made to be open at the joint. Then, by rewinding the material with a reserved allowance, the splicing channel is made to form a leak-proof connection at the joint. The pair of sealing plates at the front and rear ends of the splicing channel remain closed and do not move. That is, the front and rear ends of the splicing channel are closed by a pair of sealing plates. The splicing channel with the open joint and leak-proof connection and the closed front and rear ends can be used as a water collection tank. In other words, the present invention can splice two or more wind wall modules to form a unified water collection tank. This water collection tank passes through each wind wall module and can be used by each wind wall module.

[0016] 3) When the sealing plate is in the closed state, the upper nut and the lower nut clamp the crossbar, that is, the upper nut and the lower nut lock the crossbar to the screw to prevent the crossbar from rising or falling. This can prevent the sealing plate from being moved up accidentally, so that the sealing plate can be stably kept in the closed state; thus, it can ensure that both ends of the water collection tank are always in the closed state (the sealing plates at both ends of the water collection tank are always in the closed state), which can ensure the reliable use of the water collection tank.

[0017] 4) When the sealing plate is in the open state (i.e., the sealing plate is completely higher than the top surface of the base plate), the upper nut and lower nut clamp the crossbar, that is, the upper nut and lower nut lock the crossbar to the screw to prevent the crossbar from rising or falling. This can prevent the sealing plate from being accidentally moved down and keep the sealing plate stably in the open state; thus, it can ensure that the splicing channel remains uninterrupted at the joint (the splicing channel will not be interrupted by the sealing plate that is accidentally moved down at the joint), and also ensure the reliable use of the water collection tank.

[0018] 5) The front ends of a pair of groove sidewalls of the through groove are respectively provided with placement grooves for inserting the end of the reserved retractable material; and the left and right ends of the reserved retractable material are respectively inserted into the placement grooves of a pair of groove sidewalls; this can keep the reserved retractable material in a wound state and prevent the reserved retractable material from accidentally unwinding.

The front ends of a pair of groove sidewalls 22 of the through groove 2 are respectively provided with: placement grooves 23 for inserting the ends of the reserved excess winding material 4; the left and right ends of the reserved excess winding material 4 are respectively inserted into the placement grooves 23 of a pair of groove sidewalls 22. The waterproof sheet 3 and the reserved roll material 4 can be laid by hot-melt method.

[0022] This invention also provides a method for using the above-mentioned wind wall module, including: A single air wall module can be used alone, or two or more air wall modules can be connected together in sequence. When using the air wall module, the drainage from the equipment in each air wall module should be discharged into the same water collection tank, and then the water in the water collection tank should be discharged outwards. Specifically: like Figure 1 and Figure 2 As shown, when a wind wall module 9 is used alone, the front and rear ends of the through groove 2 of the wind wall module 9 are sealed by a pair of sealing plates 6 (the pair of sealing plates 6 at the front and rear ends of the through groove 2 remain closed and do not move), and the through groove 2 with the front and rear ends sealed is used as a water collection tank; when the water collection tank is in use, the liquid level in the water collection tank must be lower than the upper wide edge 62 of the pair of sealing plates 6 at both ends of the through groove 2 (the liquid level in the water collection tank must also be lower than the top surface of the bottom plate 1) to prevent the water in the water collection tank from overflowing. like Figure 3 and Figure 4 As shown, two or more wind wall modules ( Figure 3When two wind wall modules (91 and 92) are sequentially spliced ​​together, the end slots 2 of each wind wall module are first joined together to form a splicing channel 8. Then, the splicing channel 8 is made to be continuous at the joint 81. Then, by rewinding the material 4 with a reserved allowance, the splicing channel 8 forms a leak-proof connection at the joint 81. The front and rear ends of the splicing channel 8 are sealed by a pair of sealing plates 6. The splicing channel 8, with its continuous connection at the joint 81 and sealed at both ends, serves as a water collection tank. When using this water collection tank, the liquid level in the tank must be lower than the upper wide edge 62 of the pair of sealing plates 6 at both ends of the splicing channel 8 (the liquid level in the tank must also be lower than the top surface of the bottom plate 1) to prevent the water in the tank from overflowing. More specifically: like Figure 3 As shown, when the through slots 2 of each wind wall module are connected end to end to form the splicing through slot 8: the rear end of the through slot 2 of the previous wind wall module 91 is connected to the front end of the through slot 2 of the next wind wall module 92. like Figure 4 As shown, when the splicing groove is connected at the joint: a pair of sealing plates 6 located at the joint (i.e., a pair of sealing plates 6 located on the front and rear sides of the joint and closest to the joint) are respectively driven upward by the corresponding lifting mechanism 7 to be completely higher than the top surface of the base plate 1, so that the splicing groove 8 is connected at the joint 81; and as Figure 3 As shown, the sealing plates 6 at the non-joining points remain stationary (i.e., the pair of sealing plates 6 located at the front and rear ends of the splicing groove 8 remain closed), so that the front and rear ends of the splicing groove 8 are sealed by the pair of sealing plates 6; more specifically, as Figure 4 As shown, when the sealing plate 6 is driven to move upward by the corresponding lifting mechanism 7 to be completely higher than the top surface of the base plate 1: first, the upper nut 78 is rotated upward to be close to the bearing 77, and then the screw 75 is rotated by the throttle 76 to drive the crossbar 71 to move upward. The crossbar 71 drives the sealing plate 6 to move upward through the vertical bar 72 until the sealing plate 6 moves upward to be completely higher than the top surface of the base plate 1 (that is, the lower narrow edge 63 of the sealing plate 6 is higher than the top surface of the base plate 1). Then, the upper nut 78 is rotated downward and the lower nut 79 is rotated upward until the upper nut 78 and the lower nut 79 clamp the crossbar 71 to lock the crossbar 71 with the screw 75 and prevent the crossbar 71 from rising or falling. like Figure 3As shown, when the retractable material is reserved to form a leak-proof connection at the joint 81 of the splicing channel 8: the reserved material of the rear wind wall module 92 is taken out from the placement groove 23, and then the reserved material is rolled forward and laid on the groove wall 2 of the front wind wall module 91 (including the bottom wall 21 and a pair of side walls 22 on the left and right sides of the bottom wall 21) using the hot-melt method; and when the hot-melt method is used, the waterproof sheet 41 rolled forward from the reserved material crosses the joint 81 and overlaps the waterproof sheet 3 already laid at the rear end of the groove wall 2 of the front wind wall module 91; and the two layers of waterproof sheets 3 and 31 are bonded together by the hot-melt method so that the splicing channel 8 forms a leak-proof connection at the joint 81.

[0023] The above description is only a preferred embodiment of the present invention. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
