Description

Technical Field

[0001] The invention belongs to the technical field of air conditioner outdoor unit installation, and in particular relates to a drainage mounting bracket for a commercial air conditioner outdoor unit. Background Art

[0002] The outdoor unit of a commercial air conditioner is a key component of a large air conditioning system, responsible for removing heat from the indoor air. It is mainly composed of a compressor, a condenser, a fan, and connecting pipes. The compressor compresses the refrigerant to turn it into high-pressure gas, and the condenser dissipates heat through the fan, turning the gas into liquid. The fan helps dissipate heat and improve efficiency. The outdoor unit is connected to the indoor unit through a pipe to form a closed-loop system to ensure efficient operation and reliability of the air conditioner.

[0003] An air conditioner usually includes an outdoor unit and an indoor unit. When the air conditioner is working, they cooperate with each other to drain the condensed water. After the existing commercial air conditioner outdoor unit is installed and used for a long time, the bracket will be deformed, causing the air conditioner outdoor unit to tilt, causing drainage obstruction of the air conditioner outdoor unit, and then the condensed water after operation cannot be completely discharged due to the different terrain, causing the air conditioner outdoor unit to rust, thereby reducing the service life of the air conditioner. In addition, most commercial air conditioner outdoor units are divided into single-box and double-box. Different specifications of air conditioner outdoor units require different models of drainage brackets, which requires installers to be familiar with the drainage bracket during installation, resulting in a decrease in installation speed, thereby greatly reducing the work efficiency of the commercial air conditioner outdoor unit drainage bracket. Summary of the invention

[0004] The technical problem to be solved by the present invention is to overcome the disadvantages of the above-mentioned prior art and provide a drainage mounting bracket for an outdoor unit of a commercial air conditioner.

[0005] The technical solution adopted to solve the above technical problems is: a drainage bracket for installing an outdoor unit of a commercial air conditioner, comprising two supporting main body plates, a supporting plate is fixedly connected at the bottom between the two supporting main body plates, and a drainage mechanism is installed on the top of the supporting plate;

[0006] A fixing plate is fixedly connected between the tops of the two supporting main body plates, and a plurality of leakage holes are provided inside the supporting plate and the fixing plate;

[0007] Two auxiliary mechanisms are installed at the rear ends of the two supporting main body plates, a fixing mechanism is installed on one side of the auxiliary mechanism, and the auxiliary mechanism is fixedly connected to the fixing plate by a first fixing rod.

[0008] Furthermore, the drainage mechanism includes a motor fixedly connected to the bottom of the support plate, the motor output end is fixedly connected to a driving shaft, the outer wall of the driving shaft is rotatably connected to a meshing synchronous belt, a plurality of rotating shafts are rotatably connected inside the support plate, a plurality of rotating shafts and the top of the driving shaft are fixedly connected to a rotating head, a plurality of outer walls of the rotating heads are fixedly connected to two threaded plates, a plurality of cylinders are fixedly connected to the top of the support plate, a plurality of cylinders are slidably connected to pillars, a plurality of pillars are fixedly connected to two connecting pillars, a plurality of pillars are fixedly connected to the bottom of a first spring, a plurality of outer walls of the rotating shafts are rotatably connected to the meshing synchronous belt, a plurality of outer wall tops of the cylinders are fixedly connected to the fixed plate, a plurality of connecting pillars are respectively slidably connected to the corresponding threaded plates, and the other ends of a plurality of first springs are fixedly connected to the support plate.

[0009] Through the above technical solution, when in use, after fixing the drainage bracket to the required installation position of the outdoor unit, the commercial air-conditioning outdoor unit is then fixed to the drainage mechanism by threads or other fixing methods. The commercial air-conditioning outdoor unit installed on the drainage bracket may have some changes and adjustments to the air-conditioning outdoor unit according to environmental influences, which avoids the need to adjust the angle of the drainage bracket during installation and reduces the number of work steps. By adjusting the angle of the outdoor unit bracket, it is possible to ensure that condensed water is discharged smoothly, and moisture is prevented from accumulating inside or on the outer shell of the outdoor unit, reducing possible water leakage problems. Specifically, the commercial air-conditioning outdoor unit is fixed on multiple pillars so that the commercial air-conditioning outdoor unit can maintain a certain stability, and then the bottom of the support plate is started. The motor drives the meshing synchronous belt on the outer wall of the drive shaft to rotate. At this time, multiple rotating shafts and the rotating head on the top of the drive shaft begin to rotate, which will drive multiple threaded plates to rotate, and then the connecting column will slide downward along the outer wall of the threaded plate until the support column is driven downward. When there is condensed water inside the air-conditioning outdoor unit, the air-conditioning outdoor unit will have a certain inclination angle according to the flow of condensed water, so that the condensed water can be completely discharged to prevent the condensed water from remaining inside. When the condensed water is drained, the overall elastic force of the first spring will be greater than the gravity of the commercial air-conditioning outdoor unit, and the commercial air-conditioning outdoor unit will rebound to its original position, thereby performing reciprocating motion, so that the condensed water inside the air-conditioning outdoor unit can be completely discharged, and thus maintain a stable state.

[0010] Furthermore, the auxiliary mechanism includes a right-angle steel fixedly connected to the corner of the support plate and the fixed plate, a telescopic steel is slidably connected at the right angle inside the right-angle steel, a limiting ring is fixedly connected at the vertical part inside the right-angle steel, two second springs are fixedly connected to the bottom of the telescopic steel, the other ends of the two second springs are fixedly connected to the limiting blocks, two sliding grooves are provided on the vertical surface of the right-angle steel, the outer walls of the two limiting blocks are slidably connected to the limiting ring, and the right-angle steel and the telescopic steel are both at right angles.

[0011] Through the above technical solution, commercial air-conditioning outdoor units generally have double-box and single-box options. At this time, auxiliary mechanisms need to be used to adjust them during installation. The use of a unified bracket simplifies the installation and maintenance process. Installers only need to be familiar with one bracket design, which reduces the complexity of training and operation. The installation bracket can reduce the types of brackets that need to be stocked, thereby reducing inventory costs and management complexity. Specifically, when a double-box commercial air-conditioning outdoor unit is used, the right-angle steel is fixed to the installation wall, and then the telescopic steel is pulled upward to extend the fixed installation bracket. Because the two second spring upper limit blocks at the bottom of the telescopic steel are locked with the limit ring Interlocking, as it is pulled upward, the two second springs are repeatedly squeezed until they reach a suitable position, so as to complete the length limit requirement. When the single-box commercial air-conditioning outdoor unit is replaced with a double-box air-conditioning outdoor unit, the main change is its height, and the quality will change, so changes are needed to adapt to its changes to ensure that the drainage bracket can be installed normally during use and the commercial air-conditioning outdoor unit can operate normally. The telescopic steel is at a right angle. On the one hand, it adapts to the shape of the outdoor unit, and on the other hand, it is to be able to protect and fix multiple sides of the air-conditioning outdoor unit to ensure the safety of the air-conditioning outdoor unit, so that the double-box commercial air-conditioning outdoor unit can be stably installed.

[0012] Furthermore, the fixing mechanism includes two fixing columns fixedly connected to the telescopic steel vertical surface, the two fixing columns are fixedly connected with steel ropes, the two right-angle steel outer wall vertical surfaces are fixedly connected with a second fixing rod, the two second fixing rods are threadedly connected with threaded rods, one end of the two threaded rods are rotatably connected with a circular baffle, the other ends of the two threaded rods are fixedly connected with a rope pulley, the outer walls of the two rope pulleys are provided with rope grooves, the two steel ropes are respectively fixedly connected to the corresponding circular baffles with a third spring, the other ends of the two steel ropes are fixedly connected with a hook, the outer walls of the two fixing columns are respectively slidably connected to the corresponding sliding grooves, the two rope grooves are respectively movably connected to the corresponding steel ropes, and the other end of one of the second fixing rods is fixedly connected to the first fixing rod.

[0013] By adopting the above technical scheme, after the commercial air-conditioning outdoor unit is installed, since the weight of the double-box air-conditioning outdoor unit is greater than that of the single-box air-conditioning outdoor unit, the drainage mechanism cannot play its function. At this time, the double-box air-conditioning outdoor unit is fixed by a fixing mechanism, and the mass is reduced in the upward direction, thereby improving the practicality and draining the condensed water. Using the same bracket can reduce the installation problems caused by the mismatch of the bracket, and improve the safety and reliability of the equipment. The flexibility of this design enables the bracket to play a role in different application scenarios, thereby improving the use efficiency and economy. Specifically, the hooks at the other ends of the multiple steel ropes are used to fix the air-conditioning outdoor unit. When installing a single box It can ensure the safety of the air-conditioning outdoor unit and reduce safety hazards. Pulling the telescopic steel upwards will drive the steel ropes inside multiple fixed columns to tighten, and then drive multiple pulleys to rotate. Since the threaded rod is rotatably connected to the second fixed rod, the third spring will be compressed, and the steel rope on the pulley will be loosened. At this time, the steel rope is under force, and the commercial double-box air-conditioning outdoor unit is pulled to disperse its gravity by half. Through the hooks on multiple surfaces, the air-conditioning outdoor unit can be sufficiently stressed and lifted, so as to ensure that the drainage mechanism can discharge condensed water normally. When the drainage bracket is installed and a single box is used, the elastic force of the third spring will drive the rotation of the threaded rod, and then the steel rope will be tightened, thereby ensuring the integrity of the bracket.

[0014] The beneficial effects of the present invention are as follows: (1) By designing a drainage mechanism, an auxiliary mechanism and a fixing mechanism, the present invention can adjust the outdoor unit of a commercial air conditioner accordingly when the outdoor unit is installed and used, so that the mounting bracket can discharge the condensed water of the outdoor unit. By adjusting the angle of the outdoor unit, it can ensure that the condensed water is discharged smoothly, and the water accumulation inside or on the outer shell of the outdoor unit can be avoided, thereby reducing the possible leakage problem. In addition, when installing a commercial double-box air conditioner outdoor unit and a single-box air conditioner outdoor unit, a single mounting drainage bracket can be used, thereby increasing the applicability and functionality of the mounting drainage bracket. (2) By designing a drainage mechanism, when the outdoor unit of a commercial air conditioner is installed and used, the auxiliary mechanism and the fixing mechanism can be adjusted accordingly, so that the mounting bracket can discharge the condensed water of the outdoor unit according to the weight of the condensed water of the outdoor unit itself and the corresponding environment. The air conditioner outdoor unit can be tilted in a certain direction. First, the tilting helps the condensed water to be discharged smoothly and prevents the water from accumulating inside the equipment. Secondly, it can reduce noise and vibration and improve the operating stability of the equipment. Finally, proper tilting can optimize the working efficiency of the equipment and ensure its normal operation. (3) The present invention designs auxiliary mechanisms and fixing mechanisms. When the single-box air conditioner outdoor unit is replaced with a double-box outdoor unit, the installation drainage bracket can be changed accordingly to ensure that a single installation drainage bracket can adapt to multiple types at the same time, thereby improving the applicability of the installation drainage bracket. The unified bracket simplifies the installation and maintenance process. The installer only needs to be familiar with one bracket design, which reduces the complexity of training and operation while protecting the commercial air conditioner outdoor unit, thereby greatly improving the installation efficiency.

[0026] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0027] like Figure 1-Figure 10 As shown, a drainage bracket for installing an outdoor unit of a commercial air conditioner in this embodiment includes two supporting main body plates 1, a supporting plate 2 is fixedly connected to the bottom between the two supporting main body plates 1, a drainage mechanism 3 is installed on the top of the supporting plate 2, the drainage mechanism 3 includes a motor 301 fixedly connected to the bottom of the supporting plate 2, a driving shaft 302 is fixedly connected to the output end of the motor 301, a meshing synchronous belt 303 is rotatably connected to the outer wall of the driving shaft 302, a plurality of rotating shafts 304 are rotatably connected inside the supporting plate 2, a plurality of rotating shafts 304 and the top of the driving shaft 302 are fixedly connected to a rotating head 305, the outer walls of the plurality of rotating heads 305 are fixedly connected to two threaded plates 306, and the top of the supporting plate 2 is fixedly connected to A plurality of cylinders 307 are connected, and pillars 308 are slidably connected inside the plurality of cylinders 307, and two connecting pillars 309 are fixedly connected inside the plurality of pillars 308, and the bottoms of the plurality of pillars 308 are fixedly connected with first springs 310, and the outer walls of the plurality of rotating shafts 304 are rotatably connected with the meshing synchronous belt 303, and the tops of the outer walls of the plurality of cylinders 307 are fixedly connected with the fixing plate 4, and the plurality of connecting pillars 309 are respectively slidably connected with the corresponding threaded plates 306, and the other ends of the plurality of first springs 310 are fixedly connected with the supporting plate 2. When in use, after the drainage bracket is fixed to the required installation position of the external unit, the external unit of the commercial air conditioner is then fixed to the drainage mechanism by other fixing methods such as threads. 3. The commercial air-conditioning outdoor unit installed on the drainage bracket may have some changes and adjustments to the air-conditioning outdoor unit according to environmental influences, which avoids the need to adjust the angle of the drainage bracket during installation, reduces work steps, and ensures that condensed water is discharged smoothly by adjusting the angle of the outdoor unit bracket, avoids water accumulation inside or on the outer shell of the outdoor unit, and reduces possible water leakage problems. Specifically, the commercial air-conditioning outdoor unit is fixed on multiple pillars 308 so that the commercial air-conditioning outdoor unit can maintain a certain stability, and then the motor 301 at the bottom of the support plate 2 is started to drive the meshing synchronous belt 303 on the outer wall of the drive shaft 302 to rotate. At this time, the multiple rotating shafts 304 and the drive shaft 304 are connected to the outer wall of the drive shaft 302. 02 The rotating head 305 at the top starts to rotate, which will drive the multiple threaded plates 306 to rotate, and then the connecting column 309 will slide downward along the outer wall of the threaded plate 306 until the support column 308 is driven downward. When there is condensed water inside the air-conditioning outdoor unit, the air-conditioning outdoor unit will have a certain tilt angle according to the flow of the condensed water, so that the condensed water can be completely discharged to prevent the condensed water from remaining inside. When the condensed water is discharged, the elastic force of the overall first spring 310 will be greater than the gravity of the commercial air-conditioning outdoor unit, and the commercial air-conditioning outdoor unit will rebound to its original position, thereby performing reciprocating motion, so that the condensed water inside the air-conditioning outdoor unit can be completely discharged, and thus maintain a stable state.

[0028] like Figure 7 , Fig. 9 and Fig.10As shown, a fixing plate 4 is fixedly connected to the top between the two supporting main body plates 1, and a plurality of leakage holes 5 are opened inside the supporting plate 2 and the fixing plate 4. Two auxiliary mechanisms 6 are installed at the rear ends of the two supporting main body plates 1. The auxiliary mechanism 6 includes a right-angle steel 601 fixedly connected to the corner of the supporting plate 2 and the fixing plate 4, and a telescopic steel 602 is slidably connected at the right angle inside the right-angle steel 601. A limiting ring 603 is fixedly connected to the vertical position inside the right-angle steel 601, and two second springs 604 are fixedly connected to the bottom of the telescopic steel 602. The other ends of the springs 604 are fixedly connected to the limit blocks 605. Two slide grooves 606 are provided on the vertical surface of the right-angle steel 601. The outer walls of the two limit blocks 605 are slidably connected to the limit rings 603. The right-angle steel 601 and the telescopic steel 602 are both at right angles. Commercial air conditioner outdoor units generally have double boxes and single boxes. At this time, auxiliary mechanisms 6 need to be used to adjust them during installation. The use of a unified bracket simplifies the installation and maintenance process. Installers only need to be familiar with one bracket design, which reduces the complexity of training and operation and installation. The bracket can reduce the types of brackets that need to be stored, thereby reducing inventory costs and management complexity. Specifically, when the double-box commercial air-conditioning outdoor unit is used, the right-angle steel 601 is fixed on the installation wall, and then the telescopic steel 602 is pulled upward to extend the fixed installation bracket. Since the upper limit block 605 of the two second springs 604 at the bottom of the telescopic steel 602 is interlocked with the limit ring 603, as it is pulled upward, the two second springs 604 are repeatedly squeezed until they reach a suitable position, thereby completing the length limit required. When the single-box commercial air-conditioning outdoor unit is replaced with a double-box air-conditioning outdoor unit, its main change is its height, and its quality will change. Therefore, it is necessary to change it to adapt to its changes, ensure that the drainage bracket can be installed normally when in use, and the commercial air-conditioning outdoor unit can operate normally. The telescopic steel 602 is in a right angle shape. On the one hand, it adapts to the appearance of the outdoor unit, and on the other hand, it is to be able to protect and fix multiple sides of the air-conditioning outdoor unit to ensure the safety of the air-conditioning outdoor unit, so that the double-box commercial air-conditioning outdoor unit can be stably installed.

[0029] like Figure 7 , Figure 8 and Fig.10As shown, a fixing mechanism 7 is installed on one side of the auxiliary mechanism 6, and the auxiliary mechanism 6 is fixedly connected to the fixing plate 4 by a first fixing rod 8. The fixing mechanism 7 includes two fixing columns 701 fixedly connected to the vertical surface of the telescopic steel 602, and the two fixing columns 701 are fixedly connected to the inside of the two fixing columns 701. The vertical surfaces of the outer walls of the two right-angle steels 601 are fixedly connected to the second fixing rod 703, and one end of the two threaded rods 704 is rotatably connected to the round baffle 705, and the other ends of the two threaded rods 704 are fixedly connected to the rope pulley 706, and the outer walls of the two rope pulleys 706 are provided with rope grooves 707. The two steel ropes 702 are respectively connected to the corresponding round baffles 705. 05 is fixedly connected with a third spring 708, the other ends of the two steel ropes 702 are fixedly connected with hooks 709, the outer walls of the two fixed columns 701 are slidably connected with the corresponding slide grooves 606, and the insides of the two rope grooves 707 are movably connected with the corresponding steel ropes 702, and the other end of one of the second fixed rods 703 is fixedly connected with the first fixed rod 8. After the commercial air-conditioning outdoor unit is installed, since the weight of the double-box air-conditioning outdoor unit is greater than the weight of the single-box air-conditioning outdoor unit, the drainage mechanism 3 cannot play its function. At this time, the double-box air-conditioning outdoor unit is fixed by the fixing mechanism 7, and the mass is reduced against the rise. , thereby improving practicality while also being able to discharge condensed water. Using the same bracket can reduce installation problems caused by bracket mismatching and improve the safety and reliability of the equipment. The flexibility of this design allows the bracket to play a role in different application scenarios, thereby improving the efficiency and economy of use. Specifically, the hooks 709 at the other ends of the multiple steel ropes 702 are used to fix the air-conditioning outdoor unit, which can ensure the safety of the air-conditioning outdoor unit when installing a single box and reduce safety hazards. Pulling the telescopic steel 602 upward will drive the steel ropes 702 inside the multiple fixed columns 701 to tighten, and then drive the multiple rope wheels 706 The threaded rod 704 is rotatably connected to the second fixed rod 703, which will compress the third spring 708 and loosen the steel rope 702 on the pulley 706. At this time, the steel rope 702 is stressed and pulls the commercial double-box air-conditioner outdoor unit to disperse its gravity by half. The hooks 709 on multiple surfaces can make the air-conditioner outdoor unit sufficiently stressed and lifted, thereby ensuring that the drainage mechanism 3 can normally discharge condensed water. When the drainage bracket is installed and a single box is used, the elastic force of the third spring 708 will drive the threaded rod 704 to rotate, thereby tightening the steel rope 702 to ensure the integrity of the bracket.

[0030] The working principle of this embodiment is as follows: the commercial air-conditioning outdoor unit is fixed on multiple pillars 308 so that the commercial air-conditioning outdoor unit can maintain a certain stability, and then the motor 301 at the bottom of the support plate 2 is started to drive the meshing synchronous belt 303 on the outer wall of the drive shaft 302 to rotate. At this time, the multiple rotating shafts 304 and the rotating head 305 on the top of the drive shaft 302 begin to rotate, which will drive the multiple threaded plates 306 to rotate, and then the connecting column 309 is slid downward along the outer wall of the threaded plate 306 until the pillar 308 is driven downward. When it slides to the bottom, the first spring 310 at the bottom will rebound, and then the drainage bracket is installed for double boxes, and the hook 709 at the other end of the multiple steel ropes 702 is used to fix the air-conditioning outdoor unit. At this time, the right-angle steel 601 is fixed on the installation wall, and then the telescopic steel 602 is pulled upward to extend the fixed installation bracket. Since the upper limit block 605 of the two second springs 604 at the bottom of the telescopic steel 602 is interlocked with the limit ring 603, as it is pulled upward, the safety of the air-conditioning outdoor unit can be guaranteed when the single box is installed. Pulling the telescopic steel 602 upward will drive the steel ropes 702 inside the multiple fixed columns 701 to tighten, and then drive the multiple pulleys 706 to rotate. Since the threaded rod 704 is rotatably connected to the second fixed rod 703, the third spring 708 will be compressed, and the steel rope 702 on the pulley 706 will be loosened. At this time, the steel rope 702 is under force, so that the commercial air-conditioning outdoor unit can perform drainage operation.

[0031] The above description is only a preferred embodiment of the present invention and is not intended to limit the protection scope of the present invention.
