Description

Technical Field

[0001] This utility model relates to the field of power generation technology, and in particular to a generator built into a roller. Background Technology

[0002] In belt conveyor operation, idlers support the belt and reduce friction. Their continuous rotation makes energy recovery possible, leading to research directions for built-in generators on idlers. These generators can convert the mechanical energy of the idlers into electrical energy to power the conveyor's monitoring sensors, indicator lights, and other accessories, avoiding the cost and maintenance difficulties of long-distance wiring. However, in existing technologies, the power generation devices are mostly integrated fixed structures, with the stator and rotor directly assembled inside the idler. This lacks both a mechanical structure to control the start and stop of power generation and a convenient disassembly design, requiring the entire idler to be disassembled for maintenance or component replacement, resulting in low adaptability and maintenance efficiency.

[0003] The core flaw of existing technology is that existing idler roller generators cannot control the power generation switch and have an integrated design without a snap-fit ​​or slot structure, which means that maintenance and replacement require complete disassembly, which is cumbersome and time-consuming. Utility Model Content

[0004] The purpose of this utility model is to provide a built-in generator for the idler roller, which aims to solve the problem that the generator switch cannot be controlled and the integrated design of the structure lacks a snap-on or slot-based disassembly structure, resulting in the need for complete disassembly during maintenance and replacement, which is cumbersome and time-consuming.

[0005] The technical solution adopted in this utility model is as follows:

[0006] The idler roller has a built-in generator, including:

[0007] The fixed shaft is equipped with a buffer pad.

[0008] The outer ring of the bearing is mounted on the upper side of the fixed shaft;

[0009] A telescopic protective cover is installed on the upper side of the outer ring of the bearing;

[0010] The generator stator is installed on the inner wall of the telescopic protective cover;

[0011] The roller body is mounted on the outside of the fixed shaft.

[0012] This utility model also has the following technical features:

[0013] In one embodiment of this utility model, a dust cover is installed between the telescopic protective cover and the roller body, and a rubber dustproof ring is installed between the dust cover and the roller body.

[0014] In one embodiment of this utility model, conductive terminals are installed on the inner wall of the telescopic protective cover.

[0015] In one embodiment of this utility model, a copper coil is installed on the outside of the generator stator, the upper side of the copper coil is movably connected to a conductive terminal, a wire is installed on the outside of the conductive terminal, and a storage device is installed on the upper side of the wire.

[0016] In one embodiment of this utility model, a transmission rod is installed on the outer side of the roller body, a transmission disc is installed on the upper side of the transmission rod, and a chuck is installed on the upper side of the transmission disc.

[0017] In one embodiment of this utility model, a locking buckle is installed between the transmission rod and the transmission disc.

[0018] In one embodiment of this utility model, a generator rotor is mounted on the upper side of the claw, and a slot is mounted on the outer side of the generator rotor, the slot being movably connected to the claw.

[0019] In one embodiment of this utility model, a permanent magnet is installed on the inner side of the generator rotor.

[0020] Compared with existing technologies, the beneficial effects of this utility model are as follows: By setting a telescopic protective cover to connect the generator stator, the corresponding state of the stator and rotor can be adjusted by extending and retracting the protective cover, realizing power generation switch control, thereby meeting the flexible needs of on-demand power generation. The power generation device adopts a combination of snap-fit ​​and slot, dividing the transmission disk, rotor, and stator into three detachable parts, which can realize quick disassembly and assembly, simplify the maintenance process, and solve the problem of cumbersome and time-consuming component replacement. The transmission rod and transmission disk are equipped with locking snaps, which can strengthen the connection between the two, prevent transmission disconnection, and ensure stable power transmission. The outer side of the rotor is provided with a slot that matches the transmission disk claw, which can realize precise docking between the rotor and transmission disk, improve disassembly and assembly efficiency, and ensure convenient disassembly and replacement. The telescopic protective cover carries the stator and integrates conductive terminals, which can realize power generation control and power transmission simultaneously, optimize the structural layout, and ensure reliable functional coordination. The buffer pad installed on the fixed shaft can reduce operating vibration, protect the detachable power generation components, and extend the service life of the equipment. A dustproof component is installed between the protective cover and the roller body to prevent impurities from entering, maintain the cleanliness of the disassembly parts, and ensure a smooth disassembly and assembly process.

[0031] The following specific examples illustrate the implementation of this utility model. Those skilled in the art can easily understand other advantages and effects of this utility model from the content disclosed in this specification. This utility model can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of this utility model.

[0032] The illustrations provided in this embodiment are only schematic representations of the basic concept of this utility model. Therefore, the drawings only show the components related to this utility model and are not drawn according to the actual number, shape and size of the components. In actual implementation, the form, quantity and proportion of each component can be arbitrarily changed, and the layout of the components may also be more complex.

[0033] It should be noted that the core defects of existing idler roller built-in generators are: the generator switch cannot be controlled and the integrated design lacks a snap-fit ​​or slot-based disassembly structure, resulting in the need for complete disassembly during maintenance and replacement, which is cumbersome and time-consuming. To address this, we propose an idler roller built-in generator comprising: a fixed shaft 10 with a buffer pad; a bearing outer ring 20 mounted on the upper side of the fixed shaft 10; a telescopic protective cover 30 mounted on the upper side of the bearing outer ring 20; a generator stator 40 mounted on the inner wall of the telescopic protective cover 30; and a roller body 50 mounted on the outer side of the fixed shaft 10.

[0034] In one embodiment, a dust cover 31 is installed between the telescopic protective cover 30 and the roller body 50, and a rubber dustproof ring 32 is installed between the dust cover 31 and the roller body 50. The dust cover 31 and the rubber dustproof ring 32 form a double sealing structure. The dust cover first blocks most of the dust from entering, and the rubber dustproof ring further fills the gap between the dust cover and the roller body 50, jointly isolating external impurities and protecting the core components such as the generator stator 40 inside the telescopic protective cover 30 from contamination.

[0035] In one embodiment, the inner wall of the telescopic protective cover 30 is equipped with a conductive terminal 33. The conductive terminal 33 is fixed to the inner wall of the telescopic protective cover 30 and can move synchronously with the telescopic movement of the protective cover, providing a stable interface for establishing an electrical connection with the copper coil 41 of the generator stator 40 and realizing the conduction and transition of electrical energy.

[0036] In one embodiment, a copper coil 41 is installed on the outside of the generator stator 40. The upper side of the copper coil 41 is movably connected to the conductive terminal 33. A wire 42 is installed on the outside of the conductive terminal 33. A storage device 43 is installed on the upper side of the wire 42. After the copper coil 41 and the permanent magnet 62 of the generator rotor 60 generate an induced current, the electrical energy is conducted to the wire 42 through the movable connection with the conductive terminal 33. Then, the wire 42 transmits the electrical energy to the storage device 43 for storage, forming a complete storage circuit.

[0037] In one embodiment, a transmission rod 51 is installed on the outer side of the roller body 50, a transmission disc 52 is installed on the upper side of the transmission rod 51, and a chuck 53 is installed on the upper side of the transmission disc 52.

[0038] In one embodiment, a locking buckle 54 is installed between the transmission rod 51 and the transmission disc 52.

[0039] In one embodiment, a generator rotor 60 is mounted on the upper side of the claw 53, and a slot 61 is mounted on the outer side of the generator rotor 60, with the slot 61 being movably connected to the claw 53.

[0040] In one embodiment, a permanent magnet 62 is installed on the inner side of the generator rotor 60. The permanent magnet 62 is fixed to the inner side of the generator rotor 60. When the rotor rotates under the drive of the transmission structure, the permanent magnet 62 rotates synchronously, causing it to move relative to the copper coil 41 on the outer side of the generator stator 40, thereby cutting the magnetic field lines and providing magnetic field conditions for the copper coil 41 to generate electrical energy.

[0041] In one embodiment, see Figure 1 and Figure 2The roller 50 serves as the power source, and its rotation directly drives the transmission rod 51 mounted on the outside to rotate synchronously. The transmission rod 51 transmits power to the transmission disc 52 above it, causing the transmission disc 52 to rotate accordingly. The claws 53 on the upper side of the transmission disc 52 are adapted to the slots 61 on the outside of the generator rotor 60. Through the docking of the two, the rotational power of the transmission disc 52 is finally transmitted to the generator rotor 60, driving the rotor to rotate, completing the entire process of power transmission from the roller to the rotor.

[0042] In one embodiment, to prevent relative sliding or disengagement between the transmission rod 51 and the transmission disk 52 during power transmission, a locking buckle 54 is installed between them. The locking buckle 54 can tightly fix the transmission rod 51 and the transmission disk 52 into one unit, eliminate connection gaps, and ensure that the rotational power of the transmission rod 51 can be stably and losslessly transmitted to the transmission disk 52, providing a reliable power foundation for subsequently driving the generator rotor 60.

[0043] In another embodiment, see Figure 3 The generator rotor 60 has a slot 61 on its outer side, and a claw 53 on the upper side of the transmission disc 52. The slot 61 and the claw 53 are movably connected. When the rotor needs to be installed, simply align the slot 61 and the claw 53 to achieve power connection. When the rotor needs to be repaired or replaced, the slot and the claw can be quickly separated for disassembly, which greatly improves the convenience of maintenance operations while ensuring transmission reliability.

[0044] In summary, the built-in generator in the idler roller of this utility model, through the coordinated action of the transmission rod 51, transmission disc 52, claw 53, locking buckle 54 and slot 61, can realize the stable transmission and quick assembly / disassembly of power from the roller body 50 to the generator rotor 60, achieving the dual functions of reliable power supply and convenient component maintenance.
