Description

Technical Field

[0001] The utility model belongs to the field of vibration control, and more specifically, the utility model designs an energy collection device based on an inertia capacity damper. Background Art

[0002] Since natural disasters such as earthquakes and typhoons can cause harm to building structures, causing discomfort and panic to the human body at the least, or even damage or even collapse of the building structure at the worst, posing a serious threat to people's lives and property. Inertia containers can achieve a larger inertia with a smaller mass, that is, a larger "virtual mass". They are widely used in building structures for vibration reduction control.

[0003] Existing inertial container products are used in vibration reduction, and the main implementation mechanisms can be divided into: first, hydraulic shock absorbers, which use the compressibility of liquids and the characteristics of liquids absorbing energy when compressed and dissipating energy when flowing to achieve the purpose of reduction or elimination; second, electromagnetic inertial containers, which use the flow inertia of fluids in slender spiral tubes to achieve inertia; third, rack and pinion inertial containers, which use a structural form in which linear motors, rotary motors and rack and pinion mechanisms are coupled to achieve energy feedback vibration reduction.

[0004] However, the traditional inertia vibration reduction control device aims to eliminate energy and lacks energy collection. When natural disasters such as typhoons and earthquakes occur, the external energy supply may not be guaranteed, which seriously affects the development and stability of these wireless sensors and other electronic equipment.

[0005] Of course, in order to solve this problem, the prior art has also proposed corresponding means to solve it, such as a power generation device for collecting oscillation energy with application number: 202220230290.9. The device converts the vibration of the mounting plane into unidirectional rotational motion of the shaft, and uses the non-contact force of the magnet to drive the piezoelectric metal sheet to vibrate and generate electricity, thereby realizing the conversion and utilization of vibration energy. Its disadvantages are that there are many components during assembly, low collection efficiency, limited frequency range, high cost, etc., and its practicality is not high. Utility Model Content

[0006] An object of the present invention is to solve at least the above problems and / or disadvantages and to provide at least the advantages to be described below.

[0007] In order to achieve these purposes and other advantages according to the utility model, an energy collection device based on an inertia capacity damper is provided, characterized in that it includes:

[0008] A box body; a slide rail, which is arranged at the bottom of the box body, the slide rail is connected to a slider, and the slider is fixedly connected to a spur rack;

[0009] Gear set 1 is rotatably connected in the housing via transmission shaft 1, and the gear set 1 comprises: gear 1 and gear 2 fixedly connected to transmission shaft 1, and the gear 1 is meshed with a spur rack;

[0010] Gear set 2 is rotatably connected in the housing through transmission shaft 2, and the gear set 2 includes: gear 3 and gear 4 fixedly connected to transmission shaft 2, and the gear 3 is meshed with gear 2;

[0011] Gear set three is rotatably connected in the housing through transmission shaft three, and the gear set three includes: gear five fixedly connected to transmission shaft three, gear six connected to transmission shaft three through one-way bearing one, and gear seven connected to transmission shaft three through one-way bearing two, and the gear five is meshed with gear four;

[0012] Gear set 4 is rotatably connected in the housing via transmission shaft 5, and the gear set 4 includes: gear 9 and gear 10 fixedly connected to transmission shaft 5, and the gear 10 is meshed with gear 7;

[0013] Gear 8, which is rotatably connected in the housing through transmission shaft 4, and the gear 8 is meshed with gear 6 and gear 9;

[0014] A permanent magnet DC generator is arranged outside the box, the permanent magnet DC generator is connected in series with the circuit module, and the circuit module is connected in series with the battery;

[0015] The flywheel is fixedly connected to the transmission shaft 5 and is located outside the box body, and the transmission shaft 5 is connected to the permanent magnet DC generator roller through an elastic coupling.

[0016] Preferably, the four upper corners of the box body are fixed by two hexagonal columns using hexagonal bolts.

[0017] Preferably, the rotation direction of the one-way bearing 1 in the gear 6 is clockwise.

[0018] Preferably, the rotation direction of the one-way bearing 2 in the gear 7 is counterclockwise.

[0019] Preferably, the one-way bearing 1 and the one-way bearing 2 are counter-rotatingly mounted on the transmission shaft 3.

[0020] Preferably, the coupling is an aluminum alloy elastic coupling.

[0021] The utility model at least includes the following beneficial effects: compared with the prior art, the utility model can convert the linear motion of the rack into high-speed rotational motion through the transmission between large and small gears through the device, and the kinetic energy generated by the rotational motion is transmitted to the flywheel, and the permanent magnet generator roller is driven to rotate through the elastic linkage shaft, and the permanent magnet DC generator generates electricity, and the electrical energy is transmitted through the circuit module and stored in the battery, which can provide energy supplement for some small wireless sensor devices.

[0022] The device uses a slide rail to ensure the linear nature of the rack movement, so it is necessary to design a guide rail. The important consideration in the guide rail design is to reduce friction and improve the mechanical transmission efficiency of the overall device movement. Therefore, the guide rail slider structure is considered. The sliding between the slider and the guide rail is mainly completed through a series of rollers, which has less friction and smoother movement.

[0023] By using two opposite one-way bearings in the device, the linear reciprocating motion of the rack is converted into one-way rotation of the permanent magnet DC generator shaft, which reduces the difficulty of circuit integration, improves the energy collection efficiency of the circuit, and reduces the manpower and material costs required for battery replacement.

[0024] Other advantages, objectives and features of the present invention will be embodied in part through the following description, and in part will be understood by those skilled in the art through research and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

[0046] Working principle:

When the spur rack 12 placed on the slider moves linearly to the left, gear 1 engages with the spur rack 12 and rotates clockwise, gear 1 drives gear 2 2 on the same transmission shaft 13 (deep groove ball bearings are connected to both ends of the transmission shaft and are fixed on both sides of the box body, which can more effectively ensure that the gears rotate in a fixed position and do not deviate due to external force) to rotate clockwise, gear 3 engages with gear 2 2 and rotates counterclockwise, gear 3 drives gear 4 4 on the same transmission shaft 2 14 to rotate counterclockwise, gear 5 5 engages with gear 4 4 and rotates clockwise, gear 5 5 carries the one-way bearing on the transmission shaft 3 15, one-way bearing 1 25 engages with gear 6 and rotates clockwise, one-way bearing 2 26 disengages from gear 7 7, gear 7 does not move, gear 8 8 engages with gear 6 6 and rotates counterclockwise. The gear 9 meshes with the gear 8 and rotates clockwise. The gear 19 drives the gear 2 10 on the transmission shaft 5 17 (the gears 1-10 in the box are cylindrical spur gears made of nylon. Since nylon has good wear resistance, it is suitable for long-term operation and high-speed applications. At the same time, the nylon surface is smooth and has good self-lubricating properties, which reduces friction and wear) to rotate clockwise. The gear 7 7 meshes with the gear 10 10. The gear 7 7 idles. The transmission shaft 5 17 drives the flywheel 11 to rotate clockwise. The flywheel (a flywheel with a larger mass than the gear, the transmission shaft 5 drives the flywheel to rotate, and the flywheel will keep rotating under the action of inertia) keeps rotating under the action of inertia. The transmission shaft 5 17 drives the roller with the permanent magnet DC generator 22 to rotate clockwise through the coupling 20, completing the conversion of kinetic energy into electrical energy. The permanent magnet DC generator is connected to the permanent magnet DC generator through the series circuit module 24 ( Figure 5 As shown, the input voltage of the permanent magnet DC generator passes through the voltage stabilizing circuit module composed of the step-down voltage stabilizing chip MP1584, and through filtering and rectification, the circuit voltage is stabilized to about 5V, and the battery is charged through the charging circuit to ensure voltage output and stable electric energy to complete the energy storage.

[0048] As in the above solution, the four upper corners of the box body are fixed by two hexagonal columns using hexagonal bolts.

[0049] Working Principle: The hexagonal column is used to reinforce both sides of the box body with hexagonal head bolts, making the gear box body more stable, and the movement of the gears inside the box can also be observed.

[0050] As in the above solution, the rotation direction of the one-way bearing 1 in the gear 6 is clockwise.

[0051] Working principle: The inner ring one-way bearing drives the outer ring gear to move, gear five 5 rotates clockwise, transmission shaft three 15 rotates clockwise, at this time, the one-way bearing one 25 fixed to the transmission shaft three rotates clockwise, gear six 6 meshes with the one-way bearing one and starts to rotate clockwise;

[0052] Gear five 5 rotates counterclockwise, transmission shaft three 15 rotates counterclockwise, at this time, the one-way bearing one 25 fixed to the transmission shaft three rotates counterclockwise, gear six is ​​disengaged from the one-way bearing one and is in a non-engaged state, at this time, gear six is ​​meshed with gear eight 8 and rotates clockwise idly.

[0053] As in the above solution, the rotation direction of the one-way bearing 2 in the gear 7 is counterclockwise.

[0054] Working principle: The inner ring one-way bearing drives the outer ring gear to move, gear five 5 rotates counterclockwise, transmission shaft three 15 rotates counterclockwise, at this time, the one-way bearing two 26 fixed to the transmission shaft three rotates counterclockwise, gear seven 7 meshes with the one-way bearing two and starts to rotate counterclockwise;

[0055] Gear five 5 rotates clockwise, transmission shaft three 15 rotates clockwise, at this time, the one-way bearing two 26 fixed to the transmission shaft three rotates clockwise, and gear seven is disengaged from the one-way bearing two to a non-engaged state. At this time, gear seven is meshed with gear ten 10 to idle counterclockwise.

[0056] As in the above solution, the one-way bearing 1 and the one-way bearing 2 are counter-rotatingly installed on the transmission shaft 3.

[0057] Working principle: The installation rotation directions of one-way bearing 1 and one-way bearing 2 should be opposite, so that the two-way rotation transmitted from the gear rotation is converted into one-way motion through the one-way bearing movement, thereby ensuring that its transmission shaft 5 always rotates clockwise.

[0058] As in the above solution, the coupling adopts an aluminum alloy elastic coupling.

[0059] Working principle: The coupling connects the transmission shaft 5 through the driving shaft and the driven shaft, and rotates in one direction together with the permanent magnet generator shaft. When there is an angular deviation or axial displacement between the shafts, the elastic coupling can bend, twist or stretch to absorb these deformations. When the deformation is completed, the elastic coupling recovers to realign the transmission shafts.

[0060] Although the implementation scheme of the utility model has been disclosed as above, it is not limited to the applications listed in the specification and implementation modes. It can be fully applied to various fields suitable for the utility model. For those familiar with the art, additional modifications can be easily implemented. Therefore, without departing from the general concept defined by the claims and the scope of equivalents, the utility model is not limited to the specific details and the illustrations shown and described herein.
