Description

Technical Field

[0001] This utility model relates to the field of industrial production technology, specifically to an industrial cooling variable frequency fan. Background Technology

[0002] With the development of energy-saving concepts and variable frequency technology, industrial fans are gradually introducing variable frequency control systems to achieve precise airflow control by adjusting the motor speed.

[0003] Fans generate a lot of noise during operation. Long-term exposure to high-decibel noise can easily cause health problems such as hearing damage, headaches, and insomnia. It can also lead to distraction, slowed reaction speed, increased risk of operational errors, and threats to production safety. Moreover, continuous noise is often accompanied by abnormal vibration, which may accelerate the wear of core components such as fan bearings and motors, shorten the service life of equipment, and increase the frequency of downtime. Therefore, we have proposed an industrial cooling variable frequency fan. Utility Model Content

[0008] Furthermore, a fixing component is provided at the top of the frame, the fixing component includes a support leg connected to the top of the frame, a clamp is connected to the support leg, two clamps are provided, and the lubrication cylinder is located between the two clamps.

[0009] The above technical solution involves setting up a fixing component to position the lubrication cylinder and prevent it from shaking.

[0010] Furthermore, an oil injection assembly is provided at the top of the lubrication cylinder, the oil injection assembly including an oil injection pipe connected to the top of the lubrication cylinder, and a sealing cap is threadedly connected to the top of the oil injection pipe.

[0011] The above technical solution involves setting up an oil injection component to periodically replenish the lubrication cylinder with lubricating oil, which is then sealed with a sealing cap.

[0012] Furthermore, a buffer assembly is provided at the bottom of the frame, the buffer assembly includes a mounting base, the mounting base is threadedly connected to the frame with bolts, and a washer is provided on the mounting base.

[0013] The above technical solution involves setting up a buffer component to absorb the vibrations generated during fan operation.

[0014] Furthermore, a second motor is installed inside the slide rail, and the lead screw is connected to the output end of the second motor.

[0015] The above technical solution involves setting a second motor as the power source for the rotation of the lead screw, which drives the extrusion plate to move.

[0032] 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.

[0033] like Figures 1-4 As shown, this utility model provides a technical solution: an industrial cooling inverter fan, including a bearing 1, fan blades 2 mounted on the bearing 1, and a frame 3 mounted outside the fan blades 2, and further including:

[0034] Detection component 4 includes a mounting shell 41 connected to the top of frame 3, a spring 42 connected inside the mounting shell 41, a transmission block 43 connected to the top of the spring 42, and a contact button 44 provided at the top inside the mounting shell 41.

[0035] The noise reduction component 5 includes a lubrication cylinder 51 set on the top of the frame 3, a slide rail 52 connected to the top of the frame 3, a lead screw 53 rotatably connected inside the slide rail 52, a sliding block 54 threadedly connected to the lead screw 53, a connecting rod 55 connected to the top of the sliding block 54, an extrusion plate 56 connected to the connecting rod 55, a limit plate set on the side of the top of the frame 3 away from the extrusion plate 56, a second motor set inside the slide rail 52, the lead screw 53 connected to the output end of the second motor, and a conduit 57 connected to the bottom of the lubrication cylinder 51.

[0036] Specifically, when the bearing 1 experiences excessive friction and generates noise, it will vibrate synchronously. The vibration will be transmitted to the frame 3, and then the spring 42 inside the mounting shell 41 will vibrate, causing the transmission block 43 at the top to move and touch the contact button 44. This will send a command to the second motor to drive the lead screw 53 to rotate in the slide rail 52. The lead screw 53 will drive the sliding block 54 to slide in the slide rail 52, thereby driving the connecting rod 55 and the extrusion plate 56 at the top to move towards the lubrication cylinder 51 to extrude it. During the extrusion process, the limiting plate on the other side of the lubrication cylinder 51 will limit the lubrication cylinder 51. Then, the lubricating oil inside will drip onto the bearing 1 through the conduit 57.

[0037] Furthermore, such as Figure 2 As shown: A first motor 9 is installed on the frame 3. The output end of the first motor 9 is connected to the frame 3. A dustproof net 10 is installed on the frame 3. By installing the first motor 9, the bearing 1 and the fan blade 2 are driven to rotate. The dustproof net 10 is used to isolate external dust.

[0038] The above solutions also include the requirement that the internal lubricating oil be replenished promptly when it runs low. Figure 1 As shown: The top of the lubrication cylinder 51 is provided with an oil injection assembly 7, which includes an oil injection pipe 71 connected to the top of the lubrication cylinder 51. A sealing cap 72 is threadedly connected to the top of the oil injection pipe 71. The top of the frame 3 is provided with a fixing assembly 8, which includes a support leg 81 connected to the top of the frame 3. A clamping plate 82 is connected to the support leg 81. There are two clamping plates 82. The lubrication cylinder 51 is located between the two clamping plates 82. Lubricating oil is injected into the lubrication cylinder 51 through the oil injection pipe 71. Then the sealing cap 72 is screwed on to seal it.

[0039] The above solutions also include the need to prevent vibrations generated by the fan during operation from causing equipment shaking, such as... Figure 2 As shown: A buffer assembly 6 is provided at the bottom of the frame 3. The buffer assembly 6 includes a mounting base 61. The mounting base 61 is threadedly connected to the frame 3 by a bolt 62. A washer 63 is provided on the mounting base 61. The buffer assembly 6 is used to absorb the vibration generated during the operation of the fan.

[0040] The working principle provided by this utility model is as follows: Figures 1-4As shown: When the bearing 1 experiences excessive friction and generates noise, it will vibrate synchronously. The vibration will be transmitted to the frame 3, and then the spring 42 inside the mounting shell 41 will vibrate, causing the transmission block 43 at the top to move and touch the contact button 44. This will send a command to the second motor to drive the lead screw 53 to rotate in the slide rail 52. The lead screw 53 will drive the sliding block 54 to slide in the slide rail 52, thereby driving the connecting rod 55 and the extrusion plate 56 at the top to move towards the lubrication cylinder 51 to extrude it. During the extrusion process, the limiting plate on the other side of the lubrication cylinder 51 will limit the lubrication cylinder 51. Then, the lubricating oil inside will drip onto the bearing 1 through the conduit 57. When the lubricating oil inside is depleted, lubricating oil will be injected into the lubrication cylinder 51 through the oil injection pipe 71. Then, the sealing cap 72 will be screwed on to seal it.

[0041] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any way. Although the present utility model has been disclosed above with reference to preferred embodiments, it is not intended to limit the present utility model. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present utility model. The implementation schemes in the above embodiments can also be further combined or replaced. Any simple modifications, equivalent changes and alterations made to the above embodiments based on the technical essence of the present utility model without departing from the scope of the present utility model shall still fall within the scope of the present utility model.
