Description

Technical Field

[0001] The invention relates to the technical field of energy-saving fans, in particular to a large-scale industrial energy-saving fan fixing device. Background Art

[0002] With the rapid development of industrialization, the demand for ventilation and cooling in large spaces such as factory workshops, logistics warehouses, commercial places and animal husbandry is increasing. Traditional ventilation and cooling equipment such as small fans and central air conditioners have limited cooling effects, high energy consumption, and high costs, which are difficult to meet the needs of modern industry for high efficiency and energy saving. Therefore, large industrial energy-saving fans came into being and gradually became the preferred equipment for ventilation and cooling in these places.

[0003] However, large industrial energy-saving fans also face some technical challenges during installation and use. First, the fan itself is heavy, and the vibration and torque generated during operation are also large, which places high demands on the fixing device. Generally, high-strength materials such as Q345 steel plates are used to ensure that they can withstand the weight of the fan and the torque generated during operation, thereby improving overall stability.

[0004] However, under high-intensity installation, the vibration generated by the fan during operation cannot be buffered. Under long-term operation, the internal stress will damage the fan itself. Once the fan is worn, it may become loosely fixed, prone to shaking, loud noise and other problems, affecting the use effect and safety. Summary of the invention

[0005] The purpose of the present application is to provide a large-scale industrial energy-saving fan fixing device, which effectively improves the stability of the fan blades set on the mounting plate by connecting the connecting columns arranged around the mounting plate with the fixing seats at the bottom of the positioning plate, and at the same time, through the installation and coordination of the first spring, the second spring and the connecting ring, the fan blades can reduce vibration and noise when rotating and maintain smooth operation; the vibration generated during operation can be effectively buffered, which can reduce the wear and fatigue of various parts of the fan blades on the one hand, and extend the service life of the fan blades and their fixing devices; on the other hand, it ensures that the fan blades will not suddenly fall off or fall over during operation, thereby ensuring the safety of surrounding personnel and equipment.

[0006] To achieve the above-mentioned purpose, the present application provides a large-scale industrial energy-saving fan fixing device, including a positioning plate, a mounting plate, a fan blade and a fixing mechanism, wherein a mounting rod is fixedly arranged at the bottom of the mounting plate, and the fan blade is rotatably arranged at the bottom of the mounting rod, a power device is arranged on the mounting plate, and the output end of the power device passes through the mounting plate and the mounting rod and is connected with the fan blade, and the fixing mechanism is arranged between the mounting plate and the positioning plate; the fixing mechanism includes a fixing seat, a connecting column, a first spring and a second spring, the positioning plate is arranged above the mounting plate, and the fixing seat is fixedly arranged at the bottom of the positioning plate, the connecting columns are arranged at the four corners of the top of the mounting plate, the connecting columns are inserted into the fixing seat, and a connecting ring is arranged at one end of the connecting column located in the fixing seat, the first spring is arranged at the bottom of the connecting ring and is sleeved on the connecting column, and abuts against the inside of the fixing seat; one end of the second spring is connected to the top of the connecting ring, and the other end is connected to the top of the fixing seat; a connecting mechanism is arranged between the mounting plate and the positioning plate, and the connecting mechanism is located between adjacent fixing mechanisms.

[0007] As a further solution of the present invention: the connecting mechanism includes an articulated seat, a connecting rod, an abutment seat and a third spring, the articulated seat is fixedly arranged on the top of the mounting plate, a sliding groove is arranged at the bottom of the positioning plate, a sliding rod is arranged in the sliding groove, the abutment seat slides with the sliding rod, one end of the connecting rod is hinged to the articulated seat, and the other end is hinged to the abutment seat, the third spring is arranged on both sides of the abutment seat, and the third spring is sleeved on the sliding rod and abuts against both sides of the abutment seat.

[0008] As a further solution of the present invention: the size of the abutment seat is adapted to the slide groove.

[0009] As a further solution of the present invention: the size of the connecting column is adapted to the insertion opening at the bottom of the fixing seat, and the size of the connecting ring is larger than the connecting column.

[0010] As a further solution of the present invention: the size of the connecting ring is matched with the inner size of the fixing seat.

[0011] As a further solution of the present invention: the positioning plate is fixedly arranged on the wall.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] 1. The present invention effectively improves the stability of the fan blades on the mounting plate by connecting the connecting columns arranged around the mounting plate with the fixing seats at the bottom of the positioning plate. At the same time, through the installation and coordination of the first spring, the second spring and the connecting ring, the fan blades can reduce vibration and noise when rotating and maintain smooth operation. The vibration generated during operation can be effectively buffered, which can reduce the wear and fatigue of various parts of the fan blades and extend the service life of the fan blades and their fixing devices on the one hand; on the other hand, it ensures that the fan blades will not suddenly fall off or fall over during operation, thereby ensuring the safety of surrounding personnel and equipment.

[0014] 2. The present invention hinges one end of the connecting rod to the hinge seat and the other end to the abutment seat, so that the connecting rod can transmit the force generated by the rotation of the fan blades, and convert the force into sliding of the abutment seat in the slide groove, and buffer it through the third spring. The hinge seat is firmly fixed on the top of the mounting plate as the connection point between the connecting rod and the mounting plate, ensuring that the mounting plate can remain stable when the connecting rod transmits force and will not shake due to the movement of the connecting rod; effectively improving the stability of the fan blades during operation.

[0015] 3. The present invention ensures the stability of the abutment seat when it slides by slidingly cooperating between the slide rod and the abutment seat, and the slide rod has a guiding function, which can effectively prevent the abutment seat from sliding and deviating, thereby improving the stability of the installation of the overall connecting mechanism.

[0016] 4. In the present invention, since the size of the abutment seat closely matches the slide slot, the abutment seat can slide more smoothly and accurately in the slide slot. This precise guiding effect reduces the extra friction and vibration caused by poor sliding or deviation, thereby improving the operating efficiency of the entire connection mechanism. At the same time, the matching abutment seat can fit closely to the side wall of the slide slot, reducing the shaking phenomenon caused by excessive gap.

[0017] 5. The present invention can form a stable mechanical connection by matching the size of the connecting column with the insertion port at the bottom of the fixing seat. This reduces the shaking and loosening caused by the large gap and enhances the overall stability. At the same time, the design of the connecting ring being larger than the connecting column not only prevents it from falling off, but also overcomes the influence of the blade's own gravity through the abutment of the second spring, thereby improving the stability of the blade during operation.

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0027] like Figures 1 to 6 As shown, a large industrial energy-saving fan fixing device includes a positioning plate 1, a mounting plate 2, a fan blade 22 and a fixing mechanism, a mounting rod 21 is fixedly arranged at the bottom of the mounting plate 2, and the fan blade 22 is rotatably arranged at the bottom of the mounting rod 21, and a power device 23 is arranged on the mounting plate 2, and the output end of the power device 23 passes through the mounting plate 2 and the mounting rod 21 and is connected to the fan blade 22, and the power device 23, such as the output end of the motor, passes through the mounting plate 2 and the mounting rod 21 and is directly connected to the fan blade 22. When the power device 23 is started, the fan blade 22 is driven to rotate, generating a strong wind flow, and achieving the effect of cooling or ventilation.

[0028] The fixing mechanism is arranged between the mounting plate 2 and the positioning plate 1; the positioning plate 1 is fixedly arranged on the wall. The fixing mechanism includes a fixing seat 3, a connecting column 31, a first spring 32 and a second spring 33. The positioning plate 1 is arranged above the mounting plate 2, and the fixing seat 3 is fixedly arranged at the bottom of the positioning plate 1. The connecting columns 31 are arranged at the four corners of the top of the mounting plate 2, and the connecting columns 31 are inserted into the fixing seat 3. A connecting ring 311 is arranged at one end of the connecting column 31 located in the fixing seat 3. The first spring 32 is arranged at the bottom of the connecting ring 311 and is sleeved on the connecting column 31, and abuts against the inside of the fixing seat 3; one end of the second spring 33 is connected to the top of the connecting ring 311, and the other end is connected to the top of the fixing seat 3; a connecting mechanism is arranged between the mounting plate 2 and the positioning plate 1, and the connecting mechanism is located between adjacent fixing mechanisms.

[0029] By connecting the connecting columns 31 arranged around the mounting plate 2 with the fixing seat 3 at the bottom of the positioning plate 1, the stability of the fan blades 22 arranged on the mounting plate 2 is effectively improved. At the same time, through the installation and coordination of the first spring 32, the second spring 33 and the connecting ring 311, the fan blades 22 can reduce vibration and noise when rotating and maintain smooth operation; the vibration generated during operation can be effectively buffered, on the one hand, it can reduce the wear and fatigue of the various components of the fan blades 22, and extend the service life of the fan blades 22 and their fixing devices; on the other hand, it ensures that the fan blades 22 will not suddenly fall off or tip over during operation, thereby ensuring the safety of surrounding personnel and equipment.

[0030] The connecting mechanism includes an articulated seat 4, a connecting rod 41, an abutting seat 42 and a third spring 43. The articulated seat 4 is fixedly arranged on the top of the mounting plate 2. A sliding groove 11 is arranged at the bottom of the positioning plate 1. A sliding rod 12 is arranged in the sliding groove 11. The abutting seat 42 is slidably matched with the sliding rod 12. One end of the connecting rod 41 is hinged to the articulated seat 4, and the other end is hinged to the abutting seat 42. The third springs 43 are arranged on both sides of the abutting seat 42, and the third spring 43 is sleeved on the sliding rod 12 to abut against both sides of the abutting seat 42.

[0031] One end of the connecting rod 41 is hinged to the hinge seat 4, and the other end is hinged to the abutment seat 42, so that the connecting rod 41 can transmit the force generated by the rotation of the fan blade 22, and convert the force into the sliding of the abutment seat 42 in the slide groove 11, and is buffered by the third spring 43. The hinge seat 4 is firmly fixed to the top of the mounting plate 2 as the connection point between the connecting rod 41 and the mounting plate 2, ensuring that the mounting plate 2 can remain stable when the connecting rod 41 transmits force and will not shake due to the movement of the connecting rod 41, effectively improving the stability of the fan blade 2 during operation.

[0032] At the same time, the sliding cooperation between the slide rod 12 and the abutment seat 42 ensures the stability of the abutment seat 42 when sliding, and the slide rod 12 has a guiding function, which can effectively prevent the abutment seat 42 from sliding and deviating, thereby improving the stability of the installation of the overall connecting mechanism.

[0033] The size of the abutment seat 42 is adapted to the sliding groove 11 .

[0034] Since the size of the abutment seat 42 closely matches the slide slot 11, the abutment seat 42 can slide more smoothly and accurately in the slide slot 11. This precise guiding effect reduces the extra friction and vibration caused by poor sliding or deviation, thereby improving the operating efficiency of the entire connection mechanism. At the same time, the adapted abutment seat 42 can fit closely to the side wall of the slide slot 11, reducing the shaking phenomenon caused by excessive gap.

[0035] The size of the connecting column 31 is adapted to the insertion opening at the bottom of the fixing seat 3 , and the size of the connecting ring 311 is larger than the connecting column 31 .

[0036] By matching the size of the connecting column 31 with the insertion port at the bottom of the fixing seat 3, a stable mechanical connection can be formed. The shaking and loosening caused by the large gap are reduced, and the overall stability is enhanced. At the same time, the design that the size of the connecting ring 311 is larger than the connecting column 31 not only prevents it from falling off, but also overcomes the influence of the gravity of the fan blade 22 itself through the abutment of the second spring 33, thereby improving the stability of the fan blade 22 during operation.

[0037] Working principle of the present invention: The fixing device is mainly composed of a positioning plate 1, a mounting plate 2, a fan blade 22, a power device 23 and a fixing mechanism. The positioning plate 1 is firmly fixed to the wall as the basic support of the entire device. The mounting plate 2 is connected to the positioning plate 1 through a fixing mechanism, and the fixing mechanism includes a fixing seat 3, a connecting column 31, a first spring 32 and a second spring 33. The connecting column 31 is precisely inserted into the insertion port at the bottom of the fixing seat 3, and an elastic buffer system is formed through the cooperation of the connecting ring 311 and the first spring 32 and the second spring 33, which ensures a stable connection between the mounting plate 2 and the positioning plate 1, and can also effectively reduce the vibration and noise generated by the fan blade 22 when rotating at high speed, thereby extending the service life of the equipment.

[0038] The power device 23, such as a motor, is mounted on the mounting plate 2, and its output end directly penetrates the mounting plate 2 and the mounting rod 21, and is closely connected to the fan blades 22. When the power device 23 is started, the powerful driving force drives the fan blades 22 to rotate rapidly, generating a huge wind flow, thereby achieving a cooling or ventilation effect.

[0039] In order to further improve the stability of the installation of the fan blade 22. The hinge seat 4 in the connecting mechanism is fixed on the mounting plate 2, and the abutment seat 42 is slidably matched with the slide groove 11 at the bottom of the positioning plate 1. The two ends of the connecting rod 41 are respectively hinged to the hinge seat 4 and the abutment seat 42, which can convert the force generated when the fan blade 22 rotates into the sliding of the abutment seat 42 in the slide groove 11. The third spring 43 is sleeved on the slide rod 12 and abuts against both sides of the abutment seat 42, which plays a role of buffering and stabilization. It not only effectively disperses the force, but also prevents damage or loosening of components caused by concentrated force.

Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present application.
