Description

Technical Field

[0001] This utility model relates to the field of ventilation fan technology, and in particular to an energy-saving mixed-flow ventilation fan with remote control. Background Technology

[0002] Mixed-flow fans are a common type of ventilation equipment. Their main function is to move air mechanically. This equipment combines the characteristics of axial fans and centrifugal fans and adopts a mixed airflow design. This type of fan guides air both axially and radially through an impeller, thereby improving the efficiency of airflow.

[0003] The "energy-saving mixed-flow fan" disclosed in patent number "CN219654931U3" stores coolant in a cooling chamber, then uses the air from the fan outlet to cool the coolant in the chamber, and circulates the coolant through the inlet and outlet. The ventilation holes in the cooling chamber increase the contact area between the cooling chamber and the fan outlet, thus increasing the cooling area of ​​the chamber. However, existing mixed-flow fans generate vibrations due to friction between their internal mechanical parts during actual use. This vibration not only produces noise but also affects the overall safe operation of the device over time. The aforementioned device does not address this issue, and its overall practical safety needs improvement. Utility Model Content

[0004] The purpose of this utility model is to solve the above-mentioned problems by proposing a remotely controlled energy-saving mixed-flow ventilator, which improves the problem that existing mixed-flow ventilators will generate corresponding vibrations due to the friction of internal mechanical parts during actual use. As a result, the machine vibration will not only produce corresponding noise, but also affect the normal and safe use of the device over time.

[0005] A remote-controlled energy-saving mixed-flow ventilator includes a mixed-flow ventilator body, a dust removal and protection mechanism, a reinforcement and support mechanism, and a shock-absorbing and protection mechanism.

[0006] The dust removal and protection mechanism includes a protective filter screen, positioning ear plates, docking ear plates, fastening bolts, and fastening nuts. Two sets of semi-circular protective filter screens are spliced ​​and installed on the outer wall of the mixed-flow fan body at the air inlet position. Positioning ear plates are symmetrically arranged on the outer wall of the protective filter screen at the mesh frame position. Four sets of docking ear plates are correspondingly arranged on the outer wall of the mixed-flow fan body. The positioning ear plates and docking ear plates are all provided with cylindrical grooves for fastening bolts to pass through, and fastening nuts are threaded on the ends of the fastening bolts.

[0007] Preferably, a drive shaft is fixedly installed on the outer side wall of the mixed-flow fan body located at the fan shaft center, and the drive shaft passes through the protective filter and is connected to the limiting scraper. The limiting scraper is configured as an arc-shaped structure, and the outer side wall of the limiting scraper is in contact with the outer side wall of the protective filter.

[0008] Preferably, the reinforcing support mechanism includes an auxiliary support base, a positioning support base, a limiting T-block, and a limiting T-slot. The mixed-flow fan body is fixedly installed inside the auxiliary support base. The positioning support base is located directly below the auxiliary support base. The positioning support base is configured with a "U" shape. Two sets of limiting T-blocks are symmetrically arranged on the outer walls of the two sides at the bottom of the auxiliary support base. The inner walls of the two sides of the positioning support base are correspondingly provided with limiting T-slots for sliding installation of the limiting T-blocks.

[0009] Preferably, the positioning support base has symmetrical support base plates on both outer walls at the bottom position, and a triangular reinforcing plate is connected between the top outer wall of the support base plate and the side outer wall of the positioning support base. The top outer wall of the support base plate has symmetrical through-holes for the entire positioning device mounting groove.

[0010] Preferably, the shock absorption and protection mechanism includes a limiting cylinder, a limiting piston rod, and a support spring. Two sets of limiting cylinders are symmetrically arranged on the inner wall of the bottom end of the positioning support seat, with two limiting cylinders in the same set. A limiting piston rod is slidably installed inside the limiting cylinder. A support spring is connected between the limiting piston rod and the inner wall of the bottom end of the limiting cylinder. The protruding end of the limiting piston rod is located above the limiting cylinder, and the protruding end of the limiting piston rod is connected to the outer wall of the bottom end of the auxiliary support seat.

[0011] Preferably, the limiting cylinder is filled with damping fluid, and the outer wall of the top of the limiting piston rod located at the piston disc position is circumferentially provided with a through groove for the damping fluid to flow through.

[0012] The beneficial effects of this utility model are:

[0013] 1. When this remotely controlled energy-saving mixed-flow ventilator is in use, the vibration reduction and protection mechanism utilizes the incompressibility of the liquid combined with the damping fluid flowing in the limiting cylinder to generate additional dynamic and static pressure changes. Through the fluid dynamics characteristics, it can help reduce the overall vibration transmission of the consumable device. In this process, it can alleviate the vibration force when the consumable device is operating. On the basis of noise reduction, it can also provide a guarantee for the long-term safe use of the device. The overall structural design is ingenious and has good practical effect.

[0014] 2. This remotely controlled energy-saving mixed-flow ventilator features a design with a protective filter assembly positioned opposite the air inlet. The filter automatically blocks impurities carried in the air from reaching the outside of the device. Furthermore, the device's linkage mechanism drives a limiting scraper to move circumferentially along the side of the filter. This circumferential movement of the limiting scraper automatically cleans the dust and impurities from the outside of the filter, ensuring clean air intake and providing dust protection for the entire device. The filter is also designed to be detachable, making cleaning and maintenance convenient and practical. Attached Figure Description

[0021] 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.

[0022] In practical implementation: such as Figure 1-5As shown, a remote-controlled energy-saving mixed-flow ventilator includes a mixed-flow ventilator body 1, a dust removal and protection mechanism 2, a reinforcement and support mechanism 3, and a shock-absorbing and protection mechanism 4.

[0023] The dust removal and protection mechanism 2 includes a protective filter 21, a positioning ear plate 22, a docking ear plate 23, a fastening bolt 24, and a fastening nut 25. Two sets of semi-circular protective filters 21 are spliced ​​and installed on the outer wall of the casing of the mixed flow fan body 1 at the air inlet. Positioning ear plates 22 are symmetrically arranged on the outer wall of the protective filter 21 at the mesh frame position. Four sets of docking ear plates 23 are correspondingly arranged on the outer wall of the casing of the mixed flow fan body 1. The positioning ear plate 22 and the docking ear plate 23 are both provided with cylindrical grooves for the fastening bolt 24 to pass through. The fastening bolt 24 is threaded with a fastening nut 25 at the end. A drive shaft is fixedly installed on the outer wall of the side of the mixed flow fan body 1 at the fan shaft position. The drive shaft passes through the protective filter 21 and is connected to the limiting scraper 26. The limiting scraper 26 is set as an arc structure. The outer wall of the limiting scraper 26 is in contact with the outer wall of the side of the protective filter 21.

[0024] The protective filter 21 is designed to isolate dust carried in the air by the mixed-flow fan body 1 on the side of the protective filter 21 when the air is intake. When the mixed-flow fan body 1 is operating, the rotation of its internal drive fan will automatically drive the transmission shaft to rotate, which in turn drives the limiting scraper 26 to rotate circumferentially on the side of the protective filter 21. As the limiting scraper 26 rotates, it will automatically scrape away the dust and impurities accumulated on the outside of the protective filter 21 to achieve a cleaning effect. This ensures the cleanliness of the outside of the protective filter 21 and guarantees the normal ventilation operation of the entire device.

[0025] When the protective filter 21 needs to be removed from the side of the device for centralized cleaning and maintenance, first unscrew the fastening nut 25 from the side of the fastening bolt 24, then pull the fastening bolt 24 out from inside the positioning ear plate 22 and the docking ear plate 23. The upper protective filter 21 can then be removed directly from the side of the device in a vertically upward direction, and the lower protective filter 21 can be removed directly from the side of the device in a vertically downward direction. The installation is the same.

[0026] The reinforcing support mechanism 3 includes an auxiliary support base 31, a positioning support base 32, a limiting T-block 33, and a limiting T-groove 34. The mixed-flow fan body 1 is fixedly installed inside the auxiliary support base 31. The positioning support base 32 is located directly below the auxiliary support base 31. The positioning support base 32 is configured as a "U" shaped structure. Two sets of limiting T-blocks 33 are symmetrically arranged on the outer walls of the two sides of the bottom position of the auxiliary support base 31. The inner walls of the two sides of the positioning support base 32 are correspondingly provided with limiting T-grooves 34 for sliding installation of the limiting T-blocks 33. The outer walls of the two sides of the bottom position of the positioning support base 32 are symmetrically provided with a support base plate 35. A triangular reinforcing plate 36 is connected and installed between the top outer wall of the support base plate 35 and the side outer wall of the positioning support base 32. The top outer wall of the support base plate 35 is symmetrically provided with an installation groove for the entire positioning device.

[0027] The auxiliary support base 31 here serves to support and install the mixed flow fan body 1. The limiting T-block 33 and the limiting T-slot 34 are designed to facilitate the sliding positioning of the auxiliary support base 31 inside the positioning support base 32. The support base plate 35 on the side of the positioning support base 32 supports and installs the triangular reinforcing plate 36. The triangular reinforcing plate 36 utilizes the stability of the triangle to better reinforce and support the entire device.

[0028] The shock absorption and protection mechanism 4 includes a limiting cylinder 41, a limiting piston rod 42, and a support spring 43. Two sets of limiting cylinders 41 are symmetrically arranged on the inner wall of the bottom end of the positioning support seat 32. There are two limiting cylinders 41 in the same set. The limiting piston rod 42 is slidably installed inside the limiting cylinder 41. The support spring 43 is connected between the limiting piston rod 42 and the inner wall of the bottom end of the limiting cylinder 41. The protruding end of the limiting piston rod 42 is located above the limiting cylinder 41, and the protruding end of the limiting piston rod 42 is connected to the outer wall of the bottom end of the auxiliary support seat 31. The limiting cylinder 41 is filled with damping fluid, and a through groove for the damping fluid to flow is circumferentially opened on the outer wall of the top of the limiting piston rod 42 at the piston plate position.

[0029] When the mixed-flow fan body 1 vibrates during actual operation, the displacement of the mixed-flow fan body 1 will automatically cause the limiting T-shaped block 33 on the side of the bottom auxiliary support 31 to slide inside the limiting T-shaped groove 34. Then, the movement of the auxiliary support 31 will automatically drive the limiting piston rod 42 to slide inside the limiting cylinder 41. At this time, due to the incompressibility of the liquid, when the limiting piston rod 42 slides inside the limiting cylinder 41, it will squeeze the damping fluid from one side of the piston plate to the other side. The flow of the damping fluid in the limiting cylinder 41 will generate additional dynamic and static pressure changes, and through the fluid dynamics characteristics, it can help reduce the overall vibration transmission of the consumable device. At the same time, when the limiting piston rod 42 moves down, it will also automatically squeeze the support spring 43. Then, the support spring 43 will deform accordingly under compression and buffer part of the vibration force. It also plays an auxiliary role in the subsequent reset process of the limiting piston rod 42. Thus, through the above working process, the vibration reduction and protection effect of the mixed-flow fan body 1 can be achieved.

[0030] When using this utility model, it is hereby noted that the electric motor built into the mixed flow fan body 1 of this application is connected and controlled with a PLC controller, so as to realize the effect of remote control of the equipment to start and stop. Thus, it can be turned on when needed and turned off remotely when not needed, thereby achieving the effect of energy saving.

[0031] The protective filter 21 is designed to isolate dust carried in the air by the mixed-flow fan body 1 on the side of the protective filter 21 when the air is intake. When the mixed-flow fan body 1 is operating, the rotation of its internal drive fan will automatically drive the transmission shaft to rotate, which in turn drives the limiting scraper 26 to rotate circumferentially on the side of the protective filter 21. As the limiting scraper 26 rotates, it will automatically scrape away the dust and impurities accumulated on the outside of the protective filter 21 to achieve a cleaning effect. This ensures the cleanliness of the outside of the protective filter 21 and guarantees the normal ventilation operation of the entire device.

[0032] When the mixed-flow fan body 1 vibrates during actual operation, the displacement of the mixed-flow fan body 1 will automatically cause the limiting T-shaped block 33 on the side of the bottom auxiliary support 31 to slide inside the limiting T-shaped groove 34. Then, the movement of the auxiliary support 31 will automatically drive the limiting piston rod 42 to slide inside the limiting cylinder 41. At this time, due to the incompressibility of the liquid, when the limiting piston rod 42 slides inside the limiting cylinder 41, it will squeeze the damping fluid from one side of the piston plate to the other side. The flow of the damping fluid in the limiting cylinder 41 will generate additional dynamic and static pressure changes, and through the fluid dynamics characteristics, it can help reduce the overall vibration transmission of the consumable device. At the same time, when the limiting piston rod 42 moves down, it will also automatically squeeze the support spring 43. Then, the support spring 43 will deform accordingly under compression and buffer part of the vibration force. It also plays an auxiliary role in the subsequent reset process of the limiting piston rod 42. Thus, through the above working process, the vibration reduction and protection effect of the mixed-flow fan body 1 can be achieved.

[0033] The auxiliary support base 31 here serves to support and install the mixed flow fan body 1. The limiting T-block 33 and the limiting T-slot 34 are designed to facilitate the sliding positioning of the auxiliary support base 31 inside the positioning support base 32. The support base plate 35 on the side of the positioning support base 32 supports and installs the triangular reinforcing plate 36. The triangular reinforcing plate 36 utilizes the stability of the triangle to better reinforce and support the entire device.

[0034] It should be noted that the specific internal structure of the above-mentioned mixed-flow fan body 1 is based on existing technical structures. As for how the device is powered, it can be powered according to existing operating techniques, which are all conventional operating techniques and will not be described in detail here.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
