Description

Technical Field

[0001] The invention relates to the technical field of cooling towers, in particular to a cooling tower for a central air-conditioning centralized control system. Background Art

[0002] The cooling tower of the central air conditioning control system uses water as a circulating coolant to absorb heat from a system and discharge it into the atmosphere to reduce the water temperature. The cooling is completed through the water evaporation process, and the cooling water can be continuously recycled. It is an energy-saving and environmentally friendly equipment.

[0003] The working principle of the cooling tower is to spray hot water onto the surface of the filler, i.e. the heat dissipation material, so that it contacts the air. At this time, heat exchange occurs between the hot water and the cold air, and finally the cooled water falls into the water tank and is pumped out for recycling.

[0004] The packing of cooling tower is usually installed in the cooling tower in the form of a coiled band. In the prior art, the packing of cooling tower usually relies on manual bundling and coiling of the rolled packing into a cumulative structure, which is labor-intensive. In addition, the packing has a limited service life and needs to be replaced regularly. However, the existing cooling tower structure can only be replaced by large-scale disassembly and assembly when replacing the packing, which brings inconvenience to production.

[0005] Therefore, in order to solve the above technical problems existing in the prior art, a cooling tower for a central air-conditioning centralized control system is proposed. Summary of the invention

DETAILED DESCRIPTION

[0042] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0043] For example, see Figure 1-Figure 6A cooling tower for a central air conditioning centralized control system includes a cooling tower body 100 , a spiral track 110 is arranged in the cooling tower body 100 , a spiral groove 120 is opened on the spiral track 110 , and a filler 200 is slidably arranged in the spiral groove 120 .

[0044] The cooling tower body 100 is provided with two winding mechanisms 300 and a laying mechanism 400 , and both ends of the filler 200 are respectively installed on the two winding mechanisms 300 .

[0045] The laying mechanism 400 includes a drum 410 rotatably disposed on the cooling tower body 100 , a buckle assembly 420 is disposed on the drum 410 , a rotating rod 430 is rotatably disposed inside the drum 410 , a first guide assembly 440 is disposed on the rotating rod 430 , and the laying mechanism 400 also includes a driving assembly 450 .

[0046] When assembling the cooling tower body 100 , the drum 410 is driven to rotate by the driving assembly 450 . During the rotation of the drum 410 , the filler 200 is fixed by the snap assembly 420 , and then the snap assembly 420 is guided to spirally rise by the first guide assembly 440 , thereby laying the filler 200 in the spiral groove 120 .

[0047] The cooling tower body 100 is provided with a vent 130 and a spraying mechanism 500. When the cooling tower body 100 is in operation, hot water is sprayed toward the spiral filler 200 through the spraying mechanism 500. The hot water contacts the filler 200 and exchanges heat with the air, thereby cooling the hot water.

[0048] The cooling tower body 100 is also provided with a water tank 140 and a water outlet pipe 150 . The hot water flows into the water tank 140 and the water outlet pipe 150 after being cooled by the filler 200 .

[0049] The winding mechanism 300 includes a first support frame 310 disposed on the cooling tower body 100 . A winding drum 320 is rotatably disposed on the first support frame 310 , and the filler 200 is wound around the winding drum 320 .

[0050] The spraying mechanism 500 includes a water inlet pipe 510 disposed on the cooling tower body 100 , and a plurality of spray heads 520 are disposed on the water inlet pipe 510 .

[0051] The cooling tower body 100 is also provided with an auxiliary cooling mechanism 600 . The auxiliary cooling mechanism 600 includes a second motor 610 and a second rotating shaft 630 provided on the cooling tower body 100 . A first pulley 620 is provided on the output shaft of the second motor 610 .

[0052] The second rotating shaft 630 is provided with a blade 640 and a second pulley 650 , and the second pulley 650 is transmission-connected to the first pulley 620 via a transmission belt 660 .

[0053] In this embodiment: when the cooling tower body 100 is in operation, the hot water of the central air conditioning system enters the annular pipe part through the straight pipe part of the water inlet pipe 510, and then is sprayed downward by a circle of nozzles 520. The hot water contacts the filler 200, and exchanges heat with the air entering the cooling tower body 100 through the vent 130 by virtue of the larger surface area of ​​the filler 200, thereby achieving the purpose of cooling. The cooled water falls into the water tank 140 and then flows out from the water outlet pipe 150.

[0054] During the assembly phase of the cooling tower body 100, the filler 200 is first wound and installed on the winding drum 320 located at the lower side, and the winding drum 320 and the filler 200 thereon can be replaced. First, the rotating drum 410 rotates, and the buckle assembly 420 on the rotating drum 410 rises and fixes the filler 200 while the rotating drum 410 rotates, thereby driving the filler 200 to spirally rise along the spiral groove 120 to complete the laying. After the laying is completed, the buckle assembly 420 releases the filler 200, and the filler 200 continues to spirally rise for a certain distance, so that the other end of the filler 200 extends from the upper side of the cooling tower body 100, and then it is wound and installed on the winding drum 320 located at the upper side.

[0055] During the operation of the cooling tower body 100, when the filler 200 needs to be replaced, it is only necessary to drive the drum 410 to rotate so that the filler 200 continues to spiral up, and the old part of the filler 200 can be wound onto the winding drum 320 located on the upper side, and then the new filler 200 replaces the original position.

[0056] The operation of the second motor 610 can drive the first pulley 620 to rotate, and then drive the blades 640 to rotate through the transmission of the transmission belt 660, forming an axial flow fan, which can play a role in auxiliary cooling.

[0057] It should be noted that when the filler 200 is magnified to a microscopic angle, the surface should have a dense wave shape, which is not shown in the figure. In addition, motors can be installed on the two first support frames 310 to drive the winding drum 320 located on the lower side to rotate counterclockwise and the winding drum 320 located on the upper side to rotate clockwise to assist in laying.

[0058] Embodiment 2: This embodiment is an improvement on Embodiment 1. For details, please refer to Figure 1-Figure 10 A plurality of slots 210 are equidistantly provided on the filler 200 . The buckle assembly 420 includes a lifting slot 421 provided on the rotating drum 410 . A hook-shaped buckle 422 is slidably provided in the lifting slot 421 . The hook-shaped buckle 422 is adapted to the slot 210 .

[0059] The first guide assembly 440 includes a first guide slot 441 and a first guide rod 442 . The first guide slot 441 is formed on the rotating rod 430 . The first guide rod 442 is connected to the hook buckle 422 , and the first guide rod 442 is slidably connected in the first guide slot 441 .

[0060] The first guide groove 441 includes a trough section 4411 and a peak section 4412 which are connected to each other. When the rotating drum 410 rotates relative to the rotating rod 430, the first guide rod 442 slides along the trough section 4411 to the peak section 4412, so that the hook-shaped buckle 422 slides upward along the lifting groove 421 and is inserted into the card slot 210.

[0061] In this embodiment, the surface of the rotating rod 430 is provided with a trough section 4411, a crest section 4412, another trough section 4411 and another crest section 4412 which are connected in sequence. The first guide groove 441 is in a horizontal shape, and the crest section 4412 is in a wave shape.

[0062] First, the head of the filler 200 is inserted into the spiral groove 120, and the rotating drum 410 is controlled to rotate clockwise, while the rotating rod 430 rotates counterclockwise at a certain speed relative to the rotating drum 410. After the first guide rod 442 passes through a wave valley section 4411 and keeps rotating horizontally, the first guide rod 442 slides into the wave peak section 4412 and starts to rise, so that the hook-shaped buckle 422 rises along the lifting groove 421 and is inserted into one of the grooves 210 that is aligned. Then the hook-shaped buckle 422 will carry the filler 200 and spirally rise.

[0063] Until the first guide rod 442 slides to the top of the peak section 4412 , the filler 200 is laid to the upper outlet of the spiral groove 120 , and the first guide rod 442 starts to move downward, so that the hook-shaped buckle 422 is pulled out of the slot 210 .

[0064] In addition, two groups of buckle assemblies 420 and first guide assemblies 440 are symmetrically arranged, so that after the filler 200 spirals up along the spiral groove 120 for a distance, another group of buckle assemblies 420 fixes the filler 200 and spirals up with it, making the laying process of the filler 200 smoother.

[0065] Embodiment 3: This embodiment is an improvement on Embodiment 2. For details, please refer to Figure 1-Figure 7 The driving assembly 450 includes a second support frame 451 arranged on the cooling tower body 100, and the second support frame 451 is provided with a first motor 452 and a first rotating shaft 453, the output shaft of the first motor 452 is connected to the first rotating shaft 453, and the first rotating shaft 453 is provided with a first gear 454 and a second gear 455.

[0066] A first connecting member 456 is provided on the rotating drum 410 , a second connecting member 457 is provided on the rotating rod 430 , a third gear 458 is provided on the second connecting member 457 , a fourth gear 459 is provided on the first connecting member 456 , the first gear 454 meshes with the third gear 458 , and the second gear 455 meshes with the fourth gear 459 .

[0067] A gear ratio between the third gear 458 and the fourth gear 459 is less than one.

[0068] In this embodiment, in order to achieve that the drum 410 rotates clockwise for multiple turns at a faster speed to lay the filler 200 , the rotating rod 430 rotates counterclockwise at a slower speed relative to the drum 410 to guide the buckle assembly 420 .

[0069] First, the first motor 452 drives the first rotating shaft 453, the first gear 454 and the second gear 455 to rotate counterclockwise, and then drives the third gear 458 and the fourth gear 459 to rotate clockwise. The third gear 458 drives the second connecting member 457 and the rotating rod 430 to rotate clockwise, and the fourth gear 459 drives the first connecting member 456 and the rotating drum 410 to rotate clockwise. Since the transmission ratio of the third gear 458 and the fourth gear 459 is less than 1, the speed of the rotating rod 430 rotating clockwise is lower than that of the rotating drum 410, and the rotating rod 430 rotates counterclockwise relative to the rotating drum 410.

[0070] Embodiment 4: This embodiment is an improvement on Embodiment 3. For details, please refer to Figure 2-Figure 9 The laying mechanism 400 also includes a second guide assembly 460, which includes a second guide rod 461 arranged on the hook-shaped buckle 422, a second guide groove 462 is opened in the lifting groove 421, and the second guide rod 461 is slidably connected in the second guide groove 462.

[0071] The first guide assembly 440 further includes a connecting tube 443 disposed on the hook buckle 422 , and the first guide rod 442 is slidably connected in the connecting tube 443 .

[0072] The second guide groove 462 includes two vertical sections 4621 and two arc sections 4622. When the hook-shaped buckle 422 spirally rises with the filler 200, when the second guide groove 462 slides from the vertical section 4621 located on the outside of the rotating rod 430 to the arc section 4622 located on the upper side, and the second guide groove 462 slides from the arc section 4622 located on the upper side to the vertical section 4621 located on the inner side of the rotating rod 430, the hook-shaped buckle 422 is pulled out from the slot 210.

[0073] The second guide assembly 460 also includes a third guide rod 463 arranged on the hook-shaped buckle 422, the third guide rod 463 is located at the lower side of the second guide rod 461, and a fourth guide groove 464 is opened on the lifting groove 421. The fourth guide groove 464 has the same shape as the second guide groove 462, and the fourth guide groove 464 is located at the lower side of the second guide groove 462, and the third guide rod 463 is slidably connected in the fourth guide groove 464.

[0074] In this embodiment: since the hook-shaped buckle 422 needs to hook the filler 200, it needs to extend to the outside of the drum 410. After the hook-shaped buckle 422 is retracted and pulled out of the slot 210, the hook-shaped buckle 422 should be retracted into the drum 410 to avoid touching the filler 200 during the descent process.

[0075] Specifically, Figure 3 As shown in , the second guide groove 462 is composed of two left and right vertical grooves and two upper and lower semicircular grooves. When the hook buckle 422 rises, the second guide rod 461 slides to the upper left along the lowest side of the arc segment 4622 located at the lower side and enters the vertical segment 4621 on the left side, and then the second guide rod 461 rises along the vertical segment 4621 on the left side and enters the arc segment 4622 on the upper side. At this time, the hook buckle 422 rises with the filler 200.

[0076] When the hook-shaped buckle 422 descends, the second guide rod 461 slides to the lower right along the upper arc section 4622 and enters the vertical section 4621 on the right. At this time, the second guide rod 461 descends along the vertical section 4621 on the right, so that the hook-shaped buckle 422 is pulled out of the slot 210 and moves to the right and is retracted into the lifting slot 421 without extending out of the rotating drum 410.

[0077] The third guide rod 463 is disposed at the lower side of the second guide rod 461, and the fourth guide groove 464 is disposed at the lower side of the second guide groove 462. The third guide rod 463 slides in the fourth guide groove 464 in the same manner as the second guide rod 461 slides in the second guide groove 462. This serves to limit the hook-shaped buckle 422, so that it moves strictly along the track of the second guide groove 462.

[0078] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0079] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principles of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
