Technical Field

[0001] The utility model relates to the technical field of amusement facilities, in particular to a magnetic eddy current speed reduction mechanism with a silent effect used on amusement facilities. Background Art

[0002] With the improvement of people's living standards and the growing demand for entertainment, amusement facilities are playing an increasingly important role in people's lives. As an exciting and challenging amusement facility, zipline is loved by many tourists.

[0003] Currently, existing zipline amusement facilities usually consist of an elevated cableway and a pulley that can slide on the cableway. Visitors ride the pulley and slide at high speed on the zipline, experiencing the feeling of flying in the air.

[0004] However, existing zipline amusement facilities have the following problems:

[0005] 1. When used in terrain with large drops, the zipline can easily travel at excessive speeds. Due to gravity and inertia, the zipline often travels at high speeds. Excessive speeds also increase safety risks. If an unexpected situation occurs, it can be difficult to react quickly and control the situation, reducing the ride's adaptability and safety.

[0006] 2. Existing zipline rides are noisy during operation. When the zipline rides glide at high speed, friction between the zipline and the zipline, as well as air resistance, generate a high level of noise. This noise not only affects the visitor experience but also causes noise pollution to the surrounding environment. In scenic areas or residential areas with strict environmental requirements, the high noise levels can cause dissatisfaction among residents, hindering the installation and development of zipline rides.

[0007] Therefore, the utility model provides a magnetic eddy current deceleration mechanism with a silent effect for use in amusement facilities to solve the above problems. Utility Model Content

[0008] To this end, the technical problem to be solved by the present invention is to provide a magnetic eddy current deceleration mechanism with a silent effect for amusement facilities, which effectively solves the problem that when used in terrain with a large terrain difference, the zipline speed is easily too fast and the zipline pulley makes a lot of noise during operation.

[0009] In order to solve the above technical problems, the present invention provides the following technical solutions:

[0010] A magnetic eddy current deceleration mechanism with a silent effect for use in amusement facilities comprises at least one pulley, a rotating shaft fixedly mounted inside the pulley, magnet fixing plates provided on both sides of the pulley, the magnet fixing plates fixedly mounted on the rotating shaft, permanent magnets installed at intervals on the magnet fixing plates, outer plates provided on both sides of the pulley, the outer plates being arranged on the side of the magnet fixing plate away from the pulley, and the rotating shaft and the outer plates being rotatably connected.

[0011] Preferably, a noise reduction wheel is fixedly mounted on the outer edge of the pulley, and a noise reduction groove is provided in the middle of the noise reduction wheel.

[0012] Preferably, the cross-section of the noise reduction groove is set to be an isosceles triangle.

[0013] Preferably, the noise reduction wheel is made of polyurethane.

[0014] Preferably, inner plates are provided on both sides of the pulley, the inner plates are fixedly connected to the plate connection, and the inner plates are installed between the magnet fixing plate and the pulley.

[0015] Preferably, the side of the outer plate away from the pulley is detachably connected to a support shell, a bearing groove is provided inside the support shell, and bearings are installed at both ends of the rotating shaft, and the bearings are installed inside the bearing groove.

[0016] Preferably, there are two pulleys.

[0017] Preferably, a plurality of hollow holes are provided on the outer plate.

[0018] The technical solution of the utility model has achieved the following beneficial technical effects:

[0019] By adding a pulley, a rotating shaft, a magnet fixing plate, a permanent magnet, an outer plate, a connecting rod and a connecting plate, the magnet fixing plate rotates synchronously with the pulley, the permanent magnet generates a magnetic field, and the outer plate cuts the magnetic field generated by the permanent magnet to generate eddy currents. The eddy currents generate Lorentz force under the magnetic field, and the direction of the Lorentz force is opposite to the rotation direction of the magnet fixing plate, thereby playing a braking role, thereby achieving a deceleration effect; by adding noise reduction wheels and noise reduction grooves, the problem of high noise in the existing cable car during operation is solved; the utility model generates eddy currents by cutting the magnetic field, thereby achieving a deceleration effect, greatly improving the safety of the equipment.

DETAILED DESCRIPTION

[0027] The above and other technical contents, features and effects of the present invention are described in detail below with reference to the attached Figures 1 to 6 The detailed description of the embodiments will clearly show that the structural contents mentioned in the following embodiments are all based on the accompanying drawings.

[0028] In the description of the present invention, it should be understood that the terms "upper", "middle", "outer", "inner" and the like indicating directions or positional relationships are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0029] Various exemplary embodiments of the present invention will be described below with reference to the accompanying drawings.

[0030] The first embodiment provides a magnetic eddy current deceleration mechanism with a silent effect for an amusement facility, comprising at least one pulley 1. A single pulley 1 has low stability when in use, so in this device, two pulleys 1 are provided, a rotating shaft 2 is fixedly installed inside the pulley 1, and both ends of the rotating shaft 2 are fixedly installed in the middle of the pulley 1 by a retaining spring, so that the rotation of the pulley 1 synchronously drives the rotation 2 to rotate, a magnet fixing plate 3 is provided on both sides of the pulley 1, and the magnet fixing plate 3 is fixedly installed on the rotating shaft 2. When the pulley 1 rotates, the magnet fixing plate 3 is synchronously driven to rotate by the rotating shaft 2, and permanent magnets 4 are installed on the magnet fixing plate 3 at intervals, and the permanent magnets 4 are arranged in pairs, and different poles of the two permanent magnets 4 are fixedly installed on the same surface of the magnet fixing plate 3, and an outer plate 5 is provided on the side of the pulley 1 away from the pulley 1, and the outer plate 5 is provided on the side of the magnet fixing plate 3 away from the pulley 1, and the rotating shaft 2 and the outer plate 5 are rotatably connected, and the two outer plates 5 are connected by a connecting plate 6;

[0031] When in use, the pulley 1 is placed on the zip line. When sliding on the zip line, the pulley 1 starts to roll. The rotation of the pulley 1 synchronously drives the magnet fixing plate 3 to rotate through the rotating shaft 2. The permanent magnet 4 on the magnet fixing plate 3 generates a magnetic field. The rotation of the magnet fixing plate 3 causes the outer plate 5 to cut the magnetic field, thereby generating eddy currents. The eddy currents will generate Lorentz force under the magnetic field, and the direction of the Lorentz force is opposite to the rotation direction of the magnet fixing plate 3, thereby playing a braking role, thereby achieving a deceleration effect. Compared with using friction deceleration, it can reduce noise generation.

[0032] A noise reduction wheel 7 is fixedly installed on the outer edge of the pulley 1, and a noise reduction groove 8 is opened in the middle of the noise reduction wheel 7. The cross-section of the noise reduction groove 8 is set to an isosceles triangle. By opening the noise reduction groove 8 in the middle of the noise reduction wheel 7, noise reduction is achieved. After the noise reduction groove 8 is opened on the pulley 1, the structure of the pulley 1 changes, and its natural vibration frequency also changes accordingly, thereby reducing the occurrence of resonance and reducing noise.

[0033] The noise reduction wheel 7 is made of polyurethane material, which is oil-resistant, wear-resistant, low-temperature-resistant, aging-resistant, high-hardness and elastic.

[0034] Inner plates 9 are provided on both sides of the pulley 1, and the inner plates 9 are fixedly connected to the plate connection. The inner plates 9 are installed between the magnet fixing plate 3 and the pulley 1. The permanent magnets 4 on the magnet fixing plate 3 generate a magnetic field. The rotation of the magnet fixing plate 3 causes the inner plates 9 to cut the magnetic field at the same time, thereby generating eddy currents. The eddy currents will generate Lorentz force under the magnetic field, and the direction of the Lorentz force is opposite to the rotation direction of the magnet fixing plate 3, thereby playing a braking role, thereby achieving a deceleration effect. The deceleration effect is further achieved by setting the inner plates 9; if the resistance is too large when the inner plates 9 and the outer plates 5 are installed at the same time, the resistance can be reduced by removing the inner plates 9; when the outer plates 5 are used alone to achieve deceleration and the deceleration effect is not good, the resistance can be enhanced by adding the inner plates 9.

[0035] The side of the outer plate 5 away from the pulley 1 is detachably connected to a support shell 10, a bearing groove 11 is provided inside the support shell 10, and bearings 12 are installed at both ends of the rotating shaft 2, and the bearings 12 are installed inside the bearing groove 11. When in use, the support shell 10 is fixed to the outer plate 5 by bolts, so that it is easy to disassemble and install, and convenient for maintenance.

[0036] The outer plate 5 is provided with a plurality of hollow holes 13 to reduce the weight of the outer plate 5 and save materials.

[0037] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the claims of this patent application.
