Description

Technical Field

[0001] This utility model belongs to the technical field of fixing mechanisms, specifically relating to a fixing mechanism for a heat pump fan. Background Technology

[0002] A heat pump is a device that transfers heat energy from a low-grade heat source to a high-grade heat source. It is also a new energy technology that has received much attention worldwide. A heat pump hot air blower is an air source heat pump device designed specifically for low-temperature heating. It consists of an indoor unit and an outdoor unit. It extracts heat from the air through the reverse circulation principle and efficiently transfers it to the room. A heat pump blower fixing mechanism is required during the installation of the heat pump blower.

[0003] Most heat pump fan installation schemes only set a single layer of rubber pads or simple springs at the bottom of the fan. However, heat pump fans generate multi-directional composite vibrations during operation. In particular, the axial impact when the compressor starts and stops and the radial sway of the fan rotation cannot be effectively decomposed by a single damping layer.

[0004] In existing technologies, the mounting methods for heat pump fans are prone to insufficient vibration damping, with rigid bolts transmitting vibrations, leading to increased fan noise. Furthermore, maintenance is difficult, and there are no visual indicators for loose bolts. Relying solely on manual inspections can easily result in missed detections, causing safety hazards. Therefore, we propose a mounting mechanism for heat pump fans. Utility Model Content

[0005] To address the problems mentioned in the background section regarding the existing heat pump fan mounting methods, which are prone to insufficient vibration damping, resulting in increased fan noise due to rigid bolts transmitting vibration, and difficulties in maintenance, lack of visual indication of loose bolts, and easy omissions during manual inspections, thus posing safety hazards, this utility model provides a heat pump fan mounting mechanism.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a heat pump fan fixing mechanism, including a mounting base and a positioning top plate. Support rods are fixed at the four corners of the mounting base. A fixing base plate is horizontally fixed to the lower part of the support rods. Shock-absorbing blocks are fixed at the four corners of the upper surface of the fixing base plate. A lifting slider is sleeved on the outside of the support rods. A guide groove is provided at the connection between the lifting slider and the support rods. A positioning top plate is horizontally fixed to the inside of the lifting slider. Shock-absorbing rubber sheets are glued to the four corners of the lower end of the positioning top plate.

[0007] One end of the lifting slider is vertically fixed with a telescopic plate, and a telescopic plate is slidably connected above the telescopic plate. A reference scale line is engraved on one end face of the telescopic plate, and a fixing bolt passes through the inside of the telescopic plate.

[0008] As a preferred embodiment of the heat pump fan fixing mechanism of this utility model, positioning plates are fixed on both sides of the bottom of the mounting base, and positioning bolts are inserted inside the positioning plates.

[0009] As a preferred embodiment of the heat pump fan fixing mechanism of this utility model, the fixing base plate has a ventilation groove inside.

[0010] As a preferred embodiment of the heat pump fan fixing mechanism of this utility model, one end of the telescopic plate is vertically fixed to the positioning top plate, and the other end is sleeved inside the fixing plate.

[0011] As a preferred embodiment of the heat pump fan fixing mechanism of this utility model, the fixing plate is fixedly connected to the support rod, the fixing plate is a U-shaped channel steel, and the telescopic plate is a rectangular steel plate, and the two are slidably connected by a dovetail groove structure.

[0012] As a preferred embodiment of the heat pump fan fixing mechanism of this utility model, the reference scale line is engraved on the surface of the exposed section of the telescopic plate.

[0013] As a preferred embodiment of the heat pump fan fixing mechanism of this utility model, the shock-absorbing block is a cubic rubber part with a groove on the top.

[0014] As a preferred embodiment of the heat pump fan fixing mechanism of this utility model, the shock-absorbing sheet is a rectangular soft silicone pad with an area larger than the projected surface of the top corner of the fan.

[0015] Compared with the prior art, the beneficial effects of this utility model are: by forming a two-way buffer layer through the bottom shock-absorbing block and the top shock-absorbing film, the vibration transmission path is cut off and the noise is reduced. It is suitable for fixing heat pump fans in high-altitude, high-vibration, and high-temperature difference scenarios, and prevents the problem of insufficient shock absorption and vibration transmission by rigid bolts during the installation of heat pump fans, which leads to increased fan noise.

[0016] This application utilizes the telescopic design of the telescopic plate and the fixed plate to automatically adapt to different fan heights. The telescopic plate displacement is displayed in real time with reference scale lines, and loose bolts can be visually identified, improving maintenance response efficiency. The dual shock absorption and visual loosening feature eliminate the risk of fan falling and prevent the problems of difficult heat pump fan maintenance, lack of visual prompts for loose bolts, and easy omissions during manual inspections, which can lead to safety hazards.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example

[0024] like Figures 1-4 As shown;

[0025] A heat pump fan fixing mechanism includes a mounting base 1 and a positioning top plate 6. Support rods 4 are fixed at each of the four corners of the mounting base 1. A fixing base plate 7 is horizontally fixed to the lower part of the support rods 4. Shock-absorbing blocks 9 are fixed at each of the four corners of the upper surface of the fixing base plate 7. A lifting slider 5 is sleeved on the outside of the support rods 4. A guide groove 11 is opened at the connection between the lifting slider 5 and the support rod 4. The positioning top plate 6 is horizontally fixed to the inside of the lifting slider 5. Shock-absorbing films 10 are glued to each of the four corners of the lower end of the positioning top plate 6. A telescopic plate 12 is vertically fixed to one end of the lifting slider 5. A telescopic plate 12 is slidably connected to the upper part of the telescopic plate 12. A reference scale line 14 is engraved on one end face of the telescopic plate 12. A fixing bolt 15 passes through the inside of the telescopic plate 12.

[0026] In this implementation plan: This application uses the bottom shock-absorbing block 9 and the top shock-absorbing film 10 to form a two-way buffer layer, cutting off the vibration transmission path and reducing noise. It is suitable for fixing heat pump fans in high-altitude, high-vibration, and high-temperature difference scenarios. Through the telescopic design of the telescopic plate 12 and the fixed plate 13, it automatically adapts to different fan heights. The displacement of the telescopic plate 12 is displayed in real time by the reference scale line 14. Loose bolts can be visually identified, improving maintenance response efficiency. Double shock absorption plus visual loosening eliminates the risk of fan falling and prevents the problems of difficult heat pump fan maintenance, bolt loosening without visual prompts, and easy omissions during manual inspection, which can lead to safety hazards.

[0027] In an optional embodiment, positioning plates 2 are fixed on both sides of the bottom of the mounting base 1, and positioning bolts 3 are inserted inside the positioning plates 2.

[0028] In this implementation plan: the mounting base 1 is anchored to the roof or equipment bracket by the preset hole position of the positioning plate 2 and the positioning bolt 3.

[0029] In an optional embodiment, the fixed base plate 7 has a ventilation groove 8 inside.

[0030] In this implementation plan: the ventilation groove 8 can accelerate airflow and heat dissipation, and prevent metal parts from getting stuck due to high temperature expansion.

[0031] In an optional embodiment, one end of the telescopic plate 12 is vertically fixed to the positioning top plate 6, and the other end is sleeved inside the fixed plate 13. The fixed plate 13 is fixedly connected to the support rod 4. The fixed plate 13 is a U-shaped channel steel, and the telescopic plate 12 is a rectangular steel plate. The two are slidably connected by a dovetail groove structure.

[0032] In this implementation plan: when the positioning top plate 6 is pressed down, the telescopic plate 12 is pushed out from the sliding sleeve of the fixed plate 13, and the fixing bolt 15 is used to lock it through the docking hole between the telescopic plate 12 and the fixed plate 13, thereby forming a rigid support frame.

[0033] In an alternative embodiment, reference scale lines 14 are etched on the surface of the exposed section of the telescopic plate 12.

[0034] In this implementation plan: if the bolts loosen and cause the telescopic plate 12 to retract, the scale line will immediately become misaligned, thus achieving a visual warning.

[0035] In an optional embodiment, the shock-absorbing block 9 is a cubic rubber part with a groove on the top, and the shock-absorbing sheet 10 is a rectangular soft silicone pad with an area larger than the projected surface of the top corner of the fan.

[0036] In this implementation scheme: the damping block 9 is a cubic rubber part with a groove on the top, used to install the fan support foot; the damping sheet 10 is a rectangular soft silicone pad with an area larger than the projection surface of the top corner of the fan. The bottom damping block 9 and the top damping sheet 10 form an orthogonal damping system to cover the vibration of the positioning top plate 6. Example

[0037] like Figures 1-4 As shown, further optimizations are made based on Example 1:

[0038] The material of the shock absorber block 9 can be upgraded to low-temperature resistant silicone composite material, and a cross anti-slip texture is added to the top groove to enhance the anti-displacement performance of the fan feet in an environment of -30℃.

[0039] The surface of the shock-absorbing film 10 is enhanced with a micro-protrusion anti-slip layer to solve the slippage problem caused by condensation while maintaining shock absorption efficiency.

[0040] The ventilation slot 8 is optimized into a honeycomb porous structure, which can increase the heat dissipation area, and the slot is coated with a corrosion-resistant ceramic coating.

[0041] After the fan starts running, the honeycomb ventilation grooves 8 accelerate the diffusion of hot airflow, and together with the low-temperature resistant silicone shock-absorbing blocks 9, they suppress the cold contraction effect. When the ambient temperature is below -20℃, the micro-protrusion anti-slip layer can offset the decrease in the coefficient of friction caused by the hardening of silicone, and prevent the fan from horizontal displacement.

[0042] Working principle: First, the mounting base 1 is anchored to the roof or equipment bracket by cooperating with the preset holes of the positioning plate 2 and the positioning bolts 3. Then, the heat pump fan is placed vertically on the fixed base plate 7, with its four corners embedded in the shock-absorbing blocks 9 to achieve initial shock absorption and anti-displacement. The fixed base plate 7 has ventilation grooves 8 to accelerate airflow and heat dissipation, preventing metal parts from jamming due to high temperature expansion. Next, the positioning top plate 6 slides down along the guide slide 11, driving the lifting slider 5 to move linearly, so that the positioning top plate 6 presses the shock-absorbing film 10 on the top of the fan and simultaneously adheres to the four corners of the fan to form a top shock-absorbing layer. When the positioning top plate 6 is pressed down, the telescopic plate 12 and the... The fixed plate 13 generates relative telescopic movement; then, after it is in place, the fixed bolts 15 are used to lock the telescopic plate 12 and the fixed plate 13 through the mating holes of the telescopic plate 12 and the fixed plate 13, completing the rigid fixation. The reference scale line 14 is marked at the mating point of the telescopic plate 12 and the fixed plate 13; finally, if the bolts loosen and cause the component to shift, the misalignment of the scale line can intuitively reflect the loose state and prompt timely tightening. The bottom shock-absorbing block 9 and the top shock-absorbing film 10 form bidirectional shock absorption. When the height of the fan needs to be adjusted, it is only necessary to loosen the fixed bolts 15, slide the positioning top plate 6 to the new position and then re-lock it, without disassembling the entire mechanism.

[0043] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
