Description

Technical Field

[0001] This utility model relates to the field of air conditioning technology, and in particular to a water pump fixing structure, an outdoor air conditioning unit, and an air conditioner. Background Technology

[0002] An air conditioner is a device that uses artificial means to adjust and control indoor environmental parameters. It is widely used in homes, offices, commercial spaces, industrial workshops, and other settings to create a comfortable indoor environment or meet specific needs.

[0003] The cooling water pump in the air conditioner is installed between the outdoor unit and the cooling tower. It draws high-temperature cooling water from the condenser, pressurizes it, and delivers it to the outdoor cooling tower. The cooling water dissipates heat and cools down in the cooling tower through spraying, air convection, and other methods, before flowing back to the condenser, forming a closed loop.

[0004] In the existing technology, water pumps are usually fixed by screws at both ends. However, after the water pump is assembled, there is a compressor mounting plate on top of the pump, a compressor mounting plate bracket and partition on the left side, and heat exchanger pipes behind it. Therefore, when the water pump fails, it is difficult to replace and repair the water pump.

[0005] Therefore, how to provide a water pump fixing structure that facilitates water pump maintenance and repair is a technical problem that urgently needs to be solved by those skilled in the art. Utility Model Content

[0006] This utility model provides a water pump fixing structure, an outdoor air conditioning unit, and an air conditioner, to at least solve one of the above-mentioned problems in the prior art.

[0007] This utility model provides a water pump fixing structure for fixing the pump body, the water pump fixing structure comprising:

[0008] A fixing plate is connected to the bottom side of the pump body, and at least one first fixing hole is provided at the first end of the fixing plate; the first fixing hole is located outside the projection range of the pump body on the fixing plate;

[0009] The tray has a limiting structure on its top side; the limiting structure engages with the second end of the fixing plate; a second fixing hole is provided at the end of the tray away from the limiting structure.

[0010] Fasteners for passing through the first fixing hole and the second fixing hole.

[0011] The water pump fixing structure provided by this utility model allows the water pump to be pre-fixed on a fixing plate. The water pump with the fixing plate installed is placed on a tray, and the water pump with the fixing plate is moved backward until the fixing plate is engaged with the limiting structure, thus fixing the first end of the water pump. Finally, fasteners pass through the first and second fixing holes to fix the fixing plate and the tray together. Since the first fixing hole is located outside the projection range of the pump body on the fixing plate, the fasteners position one end of the pump body, and the limiting structure limits the other end of the water pump. Therefore, when it is necessary to disassemble the water pump, only one tool needs to be inserted into one end of the water pump to remove the fasteners, which facilitates tool insertion and operation. After removing the fasteners, the pump body can be slid out horizontally.

[0012] According to the water pump fixing structure provided by this utility model, a guide plate is provided at the second end of the fixing plate, and the limiting structure includes:

[0013] The first limiting part is disposed along the first direction;

[0014] The second limiting part is arranged in pairs perpendicularly to both sides of the first limiting part along the second direction; the two sides of the guide plate are respectively slidably adapted to the second limiting part;

[0015] The first direction is the length direction of the pump body, and the second direction is the width direction of the pump body.

[0016] With the above structure, the first limiting part restricts the fixing plate in one direction in the first direction, so as to leave a disassembly channel for the fixing plate, and the second limiting part restricts it in two directions in the second direction.

[0017] According to the water pump fixing structure provided by this utility model, the limiting structure further includes:

[0018] The clamping buffer plate is inclinedly connected to the first limiting part and slides with the guide plate and the second limiting part. The end of the guide plate is in contact with the bottom side of the clamping buffer plate, and the top side of the clamping buffer plate is in contact with the pump body.

[0019] With the above structure, the clamping buffer plate is inclinedly connected to the first limiting part. On the one hand, it can provide a buffering and flexible contact between the buffer plate and the fixed plate in the second direction, and on the other hand, it can limit and suppress the fixed plate in the third direction.

[0020] According to the water pump fixing structure provided by this utility model, the first limiting part, the second limiting part and the clamping buffer plate are integrally connected.

[0021] With the above structural design, the limiting structure is easier to manufacture.

[0022] According to the water pump fixing structure provided by this utility model, the clamping buffer plate has a chamfer on the side facing away from the first limiting part.

[0023] By setting up the above structure, the chamfering can avoid sharp edges and improve the safety of the structure.

[0024] According to a water pump fixing structure also provided by this utility model, the tray is rigidly connected to the limiting structure.

[0025] With the above structural design, the rigid connection can provide rigid constraint force for the fixed plate.

[0026] According to the water pump fixing structure provided by this utility model, there are two first fixing holes, and the two first fixing holes are located on opposite sides of the pump body.

[0027] By setting up the above structure and distributing the first fixing hole on the opposite side of the pump body, the vibration load or working torque can be converted into tension or pressure on both sides, making the force more dispersed and reducing the risk of local overload.

[0028] According to the present invention, a water pump fixing structure is provided, wherein a buffer pad is fixedly provided between the water pump and the fixing plate.

[0029] Through the above structural design, the buffer pad transforms the rigid fixing force between the water pump and the fixed plate into a soft fixing force, providing vibration buffer for the water pump and preventing damage to the water pump or breakage of the connected pipeline.

[0030] This utility model also provides an outdoor unit for an air conditioner, including a pump body and a water pump fixing structure as described above, wherein the water pump fixing structure is used to fix the water pump to one side of the compressor compartment.

[0031] The outdoor unit of the air conditioner provided by this utility model has the various advantages described above because it includes the water pump fixing structure as described above.

[0032] This utility model also provides an air conditioner, including the water pump fixing structure as described above or the air conditioner outdoor unit as described above.

[0033] The air conditioner provided by this utility model has the various advantages described above because it includes the outdoor unit described above. Attached Figure Description

[0043] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0044] In the description of the embodiments of this utility model, it should be noted that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing the embodiments of this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this utility model. In addition, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0045] The following is combined Figures 1-6 This utility model provides a water pump fixing structure for fixing a pump body 100. The water pump fixing structure includes a fixing plate 1, a tray 3, and fasteners 5.

[0046] A fixing plate 1 is connected to the bottom side of the pump body 100. The fixing plate 1 is used to bear the weight of the pump body 100 and the vibration load during operation. At least one first fixing hole 2 is provided at the first end of the fixing plate 1; the first fixing hole 2 is located outside the projection range of the pump body on the fixing plate 1. A limiting structure 4 is provided on the top side of the tray 3. The limiting structure 4 is used to lock the second end of the fixing plate 1, providing horizontal constraint and preventing the pump body 100 from lateral displacement. A second fixing hole is provided at the end of the tray 3 away from the limiting structure 4; a fastener 5 is used to pass through the first fixing hole 2 and the second fixing hole. The second fixing hole and the first fixing hole 2 are correspondingly provided, and the connection between the tray 3 and the fixing plate 1 is realized by the fastener 5.

[0047] The water pump fixing structure provided in this embodiment of the utility model has the following advantages: since the first fixing hole 2 is located outside the projection range of the pump body 100 on the fixing plate 1, the fastener 5 positions one end of the pump body 100, and the limiting structure 4 limits the other end of the pump body 100. Therefore, when it is necessary to disassemble the pump body 100, it is only necessary to insert a tool into the second end of the pump body 100 to remove the fastener, which makes it easy to insert the tool for operation; after removing the fastener 5, the pump body 100 can be slid out horizontally.

[0048] It is understood that the water pump fixing structure provided in this embodiment inserts the second end of the fixing plate 1 into the limiting structure 4 of the tray 3 to complete the initial horizontal positioning; and passes the fastener 5 through the first fixing hole 2 and the second fixing hole and tightens it to achieve vertical fixing.

[0049] In one feasible embodiment of this utility model, a guide plate 6 is provided at the second end of the fixing plate 1. The guide plate 6 is typically a rectangular flat plate structure, and its width is consistent with the width direction of the pump body 100. The two side edges of the guide plate 6 are typically smooth planes. The limiting structure includes a first limiting part 41 and a second limiting part 42. The first limiting part 41 is provided along a first direction; the second limiting parts 42 are arranged in pairs perpendicularly to both sides of the first limiting part 41 along a second direction. The two sides of the guide plate 6 are respectively slidably adapted to the second limiting part 42 to limit its horizontal displacement. The first direction is the length direction of the pump body 100, and the second direction is the width direction of the pump body 100.

[0050] In the above embodiments, during installation, the guide plate 6 is aligned with the opening end of the limiting structure 4, and the pump body 100 is pushed along the first direction. The two side edges of the guide plate 6 are smoothly inserted under the guidance of the second limiting part 42 until they reach the predetermined position. The pump body 100 is finally fixed by fasteners 5 passing through the first fixing hole 2 and the second fixing hole.

[0051] In one feasible embodiment of this utility model, the limiting structure further includes a clamping buffer plate 43, which is obliquely connected to the first limiting part 41. This oblique connection allows for dynamic clamping and vibration buffering of the pump body 100 through elastic deformation. As the guide plate 6 slides along the second limiting part 42, the end of the guide plate 6 contacts the bottom side of the clamping buffer plate 43, and the top side of the clamping buffer plate 43 abuts against the pump body 100. Even if the pump body 100 undergoes slight deformation due to temperature changes or long-term operation, the elasticity of the clamping buffer plate 43 maintains continuous contact pressure, preventing abnormal noise or fatigue failure caused by loosening in traditional rigid fixing.

[0052] Among them, the clamping buffer plate 43 can usually be made of spring steel, which has good elastic modulus and fatigue life.

[0053] In one feasible embodiment of this utility model, the first limiting part 41, the second limiting part 42, and the clamping buffer plate 43 are integrally connected. This integrated manufacturing process not only simplifies the process flow but also significantly improves the strength, reliability, and economy of the structure.

[0054] In one feasible embodiment of this utility model, the clamping buffer plate 43 has a chamfer on the side facing away from the first limiting part 41. The chamfer not only effectively prevents edge cracking but also prevents scratches on the surface coating of the guide plate 6 during assembly, protecting the integrity of the anti-corrosion layer. Therefore, the chamfering of the clamping buffer plate 43, through geometric optimization, significantly improves the assembly performance, fatigue resistance, and service life of the water pump fixing structure without increasing material costs or manufacturing complexity.

[0055] In one feasible embodiment of this utility model, the tray 3 is rigidly connected to the limiting structure 4. This connection method can significantly enhance the stability of the structure in a vibration environment by eliminating the relative movement between components. It can be rigidly connected by bolts, or the limiting structure 4 can be directly welded and fixed to the top surface of the tray 3 by argon arc welding or laser welding.

[0056] In one feasible embodiment of this utility model, there are two first fixing holes 2, and the two first fixing holes 2 are located on opposite sides of the pump body 100. With the two first fixing holes 2 distributed on opposite sides of the pump body, when the pump body is running, the vibration or axial force generated by the internal impeller rotation and fluid transport will be transmitted to the tray 3 through the first fixing holes. Fixing on opposite sides allows for uniform load distribution, avoiding stress concentration caused by fixing on only one side. Furthermore, if the pump body 100 is fixed on only one side, vibration during operation may cause the fixing bolts to bear alternating stress, making them prone to loosening over long-term use; while fixing at two points on opposite sides disperses vibration energy, reducing the peak stress at a single fixing point.

[0057] In one feasible embodiment of this utility model, a buffer pad is fixedly provided between the pump body 100 and the fixed plate 1. The buffer pad converts the rigid fixing force between the pump body 100 and the fixed plate 1 into a soft fixing force, providing vibration buffer for the pump body 100 and preventing damage to the pump body 100 or breakage of the connected pipeline.

[0058] Therefore, the water pump fixing structure provided in the first aspect embodiment of this utility model allows for easy disassembly of the pump body 100 by inserting a tool into one end of the pump body 100 to remove the fasteners. This facilitates the insertion of the tool to operate and disassemble the fasteners. After removing the fasteners, the pump body 100 can be slid out horizontally.

[0059] The second aspect of this utility model is to provide an outdoor unit for an air conditioner, including the water pump fixing structure described above.

[0060] The outdoor unit of the air conditioner provided by this utility model has the above-mentioned advantages because it includes the water pump fixing structure.

[0061] The third aspect of this utility model is to provide an air conditioner, including the water pump fixing structure as described above or the outdoor unit of the air conditioner as described above.

[0062] The air conditioner provided in this embodiment includes the water pump fixing structure or the outdoor unit of any of the above embodiments. Since the air conditioner in this embodiment adopts all the technical solutions of any of the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be repeated here.
