Description

Technical Field

[0001] This utility model relates to the field of air conditioning, and in particular to a water pump hoisting device, a liquid supply system, and an air conditioning system. Background Technology

[0002] Liquid-cooled air conditioning is an air conditioning system that uses cooling water to regulate temperature. It is now widely used in society. Liquid-cooled air conditioning has advantages such as high energy efficiency ratio, low energy consumption, strong stability, and low noise.

[0003] In liquid-cooled air conditioning systems, the liquid supply system is an indispensable component, and the water pump is the driving force of this system. The main function of the water pump is to drive the circulation of the refrigerant and other cooling media (such as water or ethylene glycol solution) within the air conditioning system, ensuring a stable delivery of the cooling media to the loads requiring cooling. Simultaneously, the water pump can raise the liquid level, ensuring stable flow of the cooling media in the pipelines and preventing cavitation and localized overheating. More importantly, the water pump effectively improves heat exchange efficiency. Under high-load operating conditions, the water pump can provide emergency cooling, enhancing the air conditioner's cooling capacity. Therefore, the water pump is crucial for liquid-cooled air conditioning systems, and its performance directly affects the cooling effect, energy efficiency, stability, and service life of the air conditioner.

[0004] As mentioned above, the water pump is crucial. When the water pump malfunctions, emergency repairs are required. Currently, the installation and repair of water pumps in liquid-cooled air conditioning systems mainly rely on a combination of lifting equipment and manual handling to disassemble and install the water pump from the air conditioning unit. This presents the following problems: 1. The need for lifting equipment (cranes, etc.) increases construction costs. Water pumps have a certain weight, and manual handling consumes a lot of time and manpower, resulting in low efficiency. 2. During the handling process, human factors can easily lead to equipment damage or personnel injury. 3. After the liquid-cooled air conditioning unit is installed, the maintenance space near the unit is limited. Water pump repair requires a certain amount of maintenance space, and limited space will prevent the water pump from being removed in a timely manner, causing inconvenience for water pump maintenance.

[0005] Therefore, how to design a water pump hoisting device, liquid supply system, and air conditioning system that can remove the water pump from the maintenance space, overcome the limitations of the maintenance space, and improve maintenance efficiency is a technical problem that the industry urgently needs to solve.

[0012] Furthermore, the bushing assembly 3 includes a fixed shaft 11 that is fitted to the first pulley assembly 1 at the top and a bushing 12 that is fitted to the second guide rail 4 at the bottom. The bushing 12 can rotate around the fixed shaft 11 to adjust the setting direction of the second guide rail 4.

[0013] Furthermore, it also includes multiple through holes provided on the fixed shaft 11 and the bushing 12, and fixing pins 13 passing through the through holes on both the fixed shaft 11 and the bushing 12.

Detailed Implementation

[0031] To make the technical problems, technical solutions, and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0032] Therefore, a feature pointed out in this specification is used to describe one feature of one embodiment of the present invention, and does not imply that every embodiment of the present invention must have the described feature. Furthermore, it should be noted that this specification describes many features. Although certain features may be combined to illustrate possible system designs, these features may also be used in other combinations not explicitly stated. Therefore, unless otherwise stated, the described combinations are not intended to be limiting.

[0033] The principle and structure of this utility model will be described in detail below with reference to the accompanying drawings and embodiments.

[0034] Currently, water pump maintenance is hampered by limited space, making the process difficult. Please refer to [link / reference needed]. Figure 1 The outer frame is the liquid-cooled air conditioning unit, and the space inside the frame is for placing water pumps. The internal maintenance space is limited, which affects the maintenance efficiency of the staff.

[0035] For the above issues, please refer to Figure 2 This utility model proposes a water pump hoisting device, which includes a first guide rail 2 fixedly assembled, and a second guide rail 4 assembled on the first guide rail 2 through a first pulley assembly 1. The first pulley assembly 1 can drive the second guide rail 4 to move along the setting direction of the first guide rail 2.

[0036] A second pulley assembly 5 for hoisting the water pump 7 is provided on the second guide rail 4. The second pulley assembly 5 can drive the water pump 7 to move along the direction set by the second guide rail 4.

[0037] As attached Figure 1 As shown, the frame of the liquid-cooled air conditioner has many crossbeams. The first guide rail 2 in this utility model is fixedly mounted on the crossbeam. The first pulley assembly 1 can drive the second guide rail 4 to move, and the second pulley assembly 5 can drive the water pump 7 to move. By setting up the two pulley assemblies, the water pump 7 can be taken out from the maintenance space, thereby overcoming the limitation of the maintenance space and improving maintenance efficiency.

[0038] The present invention uses two guide rails instead of one because the water pump 7 is entirely within the frame of the liquid-cooled air conditioner. Using only one guide rail would make it difficult to completely remove the water pump 7 from the maintenance space. With two guide rails, even if the first pulley assembly 1 cannot completely remove the second guide rail 4 from the maintenance space, the second pulley assembly 5 can further move the water pump 7, thereby allowing it to be removed from the maintenance space. This maintenance state corresponds to the attached... Figure 8 .

[0039] In other words, through the above-mentioned double guide rail structure, this utility model can fully ensure that the water pump 7 can be smoothly removed from the maintenance space, thereby overcoming the limitations of the maintenance space and improving maintenance efficiency.

[0040] Please see Figure 2 The present invention also includes a bushing assembly 3 for assembling the first pulley assembly 1 and the second guide rail 4. The part of the bushing assembly 3 that is assembled with the second guide rail 4 can rotate relative to the part of the bushing assembly 3 that is assembled with the first pulley assembly 1, so as to adjust the setting direction of the second guide rail 4.

[0041] As mentioned above, the second guide rail 4 can be driven by the first pulley assembly 1 to move along the first guide rail 2. In some usage scenarios, the main body of the water pump 7 can be removed from the maintenance space by using the first pulley assembly 1. At this time, simply rotating the second guide rail 4 will allow the water pump 7 to be completely removed from the maintenance space. The bushing assembly 3 in this utility model is used to rotate the second guide rail 4 and adjust its setting direction, so that the water pump 7 can be removed from the maintenance space without being driven by the second pulley assembly 5. This maintenance state corresponds to the attached... Figure 9 In addition, this maintenance state can also be used to adjust the position of the water pump 7. For example, if there is insufficient maintenance space outside the frame, the second guide rail 4 can be rotated through the bushing assembly 3 to change the placement direction of the water pump 7 and save maintenance space.

[0042] In other words, through the above-mentioned bushing assembly 3, the position of the water pump 7 can be adjusted more flexibly, allowing it to be removed from the maintenance space and improving maintenance efficiency.

[0043] Please see Figure 2 The present invention also includes a hoist 6 installed on the second pulley assembly 5. The hoist 6 is used to hoist the water pump 7 and can adjust the hoisting height of the water pump 7.

[0044] Here, the hoist 6, as a common lifting device, can easily lift the water pump 7, thereby achieving the purpose of adjusting the lifting height of the water pump 7;

[0045] Based on the preceding discussion, it can be seen that the structure for adjusting the position of the water pump 7 in this invention consists of a first pulley assembly 1, a second pulley assembly 5, a bushing assembly 3, and a hoist 6. The first pulley assembly 1 can adjust the position of the second guide rail 4 along the direction of the first guide rail 2, thereby adjusting the position of the water pump 7. The second pulley assembly 5 can adjust the position of the water pump 7 along the direction of the second guide rail 2. The bushing assembly 3 can adjust the direction of the second guide rail 4, thereby adjusting the orientation of the water pump 7. The hoist 6 can adjust the height of the water pump 7. In other words, through the above structural design, this invention can achieve omnidirectional position adjustment of the water pump 7. This not only ensures that the water pump 7 can be easily removed from the maintenance space but also allows it to be adjusted to a position suitable for maintenance personnel, further improving the convenience of maintenance.

[0046] In this utility model, the first pulley assembly 1 and the second pulley assembly 5 have exactly the same structural configuration, which is illustrated in the appendix below. Figure 3 and appendix Figure 4 The structure of the first pulley assembly 1 and the second pulley assembly 4 in this utility model will be described;

[0047] Please see Figure 3 The first pulley assembly 1 includes at least side plates 9 disposed on both sides of the first guide rail 2, and a fixing rod 10 connecting and fixing the side plates 9 on both sides of the first guide rail 2. A pulley 8 is disposed on the side of the side plate 9 facing the first guide rail 2, and the pulley 8 is placed on the first guide rail 2.

[0048] Here, pulley 8 can rotate on side plate 9, from the attached Figure 3 It can be clearly seen that a certain space is reserved between the two side plates 9, which can hold the first guide rail 2 in the middle, and then place the pulley 8 on the first guide rail 2. It can also prevent the first pulley assembly 1 from falling off the first guide rail 2. The fixing rod 10 is used to fix and adjust the position of the side plates 9 on both sides.

[0049] The assembly method of the second pulley assembly 5 and the second guide rail 4 is the same as that of the first pulley assembly 1 and the first guide rail 2, and will not be described again here;

[0050] From the appendix Figure 3 It is quite evident that a certain mounting position is reserved on the bottom fixing rod 10 of the first pulley assembly 1, which can be used for welding the bushing assembly 3. Please refer to [link / reference]. Figure 4 For the second pulley assembly 5, this mounting position can be used to assemble the hoist 6;

[0051] That is, through the structural arrangement of the first pulley assembly 1 and the second pulley assembly 5, this utility model can not only ensure the assembly with the device to be moved, but also realize its movement on the first guide rail 2 or the second guide rail 4. As mentioned above, it can drive the second guide rail 4 to move along the setting direction of the first guide rail 2 and drive the hoist 6 to move along the setting direction of the second guide rail 4.

[0052] Please see Figure 5 and Figure 6 The bushing assembly 3 of this utility model includes a fixed shaft 11 that is assembled with the first pulley assembly 1 at the top and a bushing 12 that is assembled with the second guide rail 4 at the bottom. The bushing 12 can rotate with the fixed shaft 11 as the axis to adjust the setting direction of the second guide rail 4.

[0053] The bushing assembly 3 also includes a plurality of through holes provided on the fixed shaft 11 and the bushing 12, and a fixing pin 13 passing through the through holes on both the fixed shaft 11 and the bushing 12. The fixing pin 13 is used to fix the relative position of the fixed shaft 11 and the bushing 12.

[0054] Please see Figure 5 The top of the fixed shaft 11 of the bushing assembly 3 is welded to the first pulley assembly 1, and the bottom of the bushing 12 of the bushing assembly 3 is welded to the second guide rail 4. Since the bushing 12 can rotate relative to the fixed shaft 11, it can drive the second guide rail 4 to rotate relative to the first pulley assembly 1. Since the first pulley assembly 1 is mounted on the first guide rail 2, the rotation of the second guide rail 4 relative to the first guide rail 2 can be realized through the setting of the fixed shaft 11 and the bushing 12, thereby realizing the adjustment of the setting direction of the second guide rail 4.

[0055] The aforementioned fixing pin 13 is used to fix the fixing shaft 11 and the bushing 12. Since the fixing shaft 11 and the bushing 12 can rotate relative to each other, if the fixing pin 13 is not set for fixation, the bushing 12 may rotate relative to the fixing shaft 11 when the staff is repairing the water pump 7, causing the second guide rail 4 to rotate, and then causing the water pump 7 to rotate, which may pose a safety hazard to the staff.

[0056] With the setting of the fixing pin 13, this utility model can fix the bushing 12 relative to the fixed shaft 11, avoiding the problem of rotation by the staff when maintaining the water pump 7, which poses a safety hazard.

[0057] Furthermore, in this utility model, the hoist 6 and the second pulley assembly 5 are detachably connected.

[0058] The first pulley assembly 1 and the first guide rail 2, as well as the second pulley assembly 5 and the second guide rail 4, are detachably connected.

[0059] Here, the above structure is designed as a detachable connection so that when the water pump 7 is operating normally and does not require maintenance, and when it is not necessary to hoist the water pump 7, the hoist 6, the first pulley assembly 1, and the second pulley assembly 5 can be removed, further saving maintenance space. Please refer to [link to relevant documentation]. Figure 3 In this utility model, the two side plates 9 of the first pulley assembly 1 and the second pulley assembly 5 are actually fixedly assembled by a fixing rod 10. When disassembling, only the fixing rod 10 needs to be removed.

[0060] The following sections will be combined with the appendix. Figure 7 Appendix Figure 8 Appendix Figure 9 The various maintenance conditions of this utility model are described below:

[0061] 1. When the water pump 7 is running normally and does not require maintenance, the first pulley assembly 1, the second pulley assembly 5, and the hoist 6 can be removed and stored by themselves. That is, only the first guide rail 2 welded to it remains on the frame, and the water pump 7 is not hoisted.

[0062] 2. When the maintenance position of water pump 7 is on the outer side, and the entire water pump 7 does not need to be hoisted for maintenance, only the first guide rail 2 is needed. The second pulley assembly 5 can be directly installed on the first guide rail 2. The operator can adjust the position of the second pulley assembly 5 according to the maintenance position of water pump 7. The second pulley assembly 5 then drives the hoist 6 to hoist the water pump 7 to the designated maintenance position, such as... Figure 7 As shown.

[0063] 3. When the maintenance position of water pump 7 is located on the inner side, and it is necessary to lift the entire water pump 7 out, if the distance via the first guide rail 2 alone is insufficient, a double-layer guide rail must be used. In this case, the first pulley assembly 1 is installed on the first guide rail 2. The first pulley assembly 1 has a bushing assembly 3 welded to it and a second guide rail 4 below it. Then, the second pulley assembly 5 is installed on the second guide rail 4. The operator can adjust the positions of the first pulley assembly 1 and the second pulley assembly 5 according to the maintenance position of water pump 7. The second pulley assembly 5 drives the hoist 6 to lift the water pump 7 to the designated maintenance position. Figure 8 As shown.

[0064] In this state, the water pump 7 can be lifted out of the frame of the liquid-cooled air conditioner, making it easier to carry out maintenance work. However, since the water pump 7 of the liquid-cooled air conditioner has a certain length, there must be sufficient maintenance space outside the frame when the water pump 7 is completely lifted out of the frame of the liquid-cooled air conditioner.

[0065] 4. When there is insufficient maintenance space outside the frame, the retaining pin 13 of the bushing assembly 3 can be pulled out, causing the bushing 12 to rotate around the fixed shaft 11, thereby rotating the second guide rail 4 and changing its orientation. Figure 9As shown, the rotation of the bushing assembly 3 can make the second guide rail 4 perpendicular to the first guide rail 2. The staff can adjust the position of the second pulley assembly 5 on the second guide rail 4 according to the maintenance position of the water pump 7. The second pulley assembly 5 then drives the hoist 6 to lift the water pump 7 to the designated maintenance position.

[0066] In situations where maintenance space is insufficient, by changing the orientation of the second guide rail 4, the water pump 7 can be lifted out and rotated freely, moving both horizontally and vertically, overcoming the limitations of maintenance space and facilitating timely maintenance of the water pump.

[0067] After the water pump has been repaired, the staff can use this utility model to lift and reset the water pump 7. This lifting structure is simple to operate and easy to install and disassemble.

[0068] The advantages of this utility model are: the water pumps of traditional liquid-cooled air conditioners have high equipment costs, high time costs, and low efficiency during installation and maintenance, which can easily lead to equipment damage or personal injury. The maintenance efficiency is very low, which greatly affects the safety, stability and reliability of liquid-cooled air conditioner maintenance.

[0069] This invention eliminates the need for other equipment, significantly reducing installation and maintenance costs. It also reduces labor intensity and greatly improves efficiency. Reduced human error ensures the safety of staff and air conditioning equipment. In situations with limited space, the water pump can be quickly and safely removed, greatly improving maintenance efficiency. The use of this hoisting device effectively enhances the safety, stability, and reliability of liquid-cooled air conditioning maintenance.

[0070] This utility model also proposes a liquid supply system, which has the above-mentioned water pump hoisting device.

[0071] This utility model also proposes an air conditioning system having the above-mentioned liquid supply system.

[0072] In summary, compared with the prior art, the present invention has at least the following beneficial effects:

[0073] When installing and maintaining a water pump, this invention can move the water pump using a first pulley assembly, a second pulley assembly, and a hoist, eliminating the need for lifting equipment and reducing installation and maintenance costs. Furthermore, when maintaining a water pump, this invention can remove the water pump from the maintenance space, overcoming the limitations of the maintenance space and greatly improving maintenance efficiency.

[0074] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
