Description

Technical Field

[0001] This invention relates to the field of tunnel inspection technology, and more specifically, to a plate-type sand-proof and wind power generation combined device. Background Technology

[0002] Northwest my country boasts abundant sunshine and heat resources, but its geographical distance from the ocean results in scarce rainfall, an arid climate, sparse vegetation, and a landscape dominated by Gobi deserts, grasslands, and frequent sandstorms. These environmental characteristics prevent the effective fixation of sand and soil, making it susceptible to sandstorms caused by wind. Consequently, sandstorms have impacted the safe operation of railways in Northwest China, making sand control and prevention an urgent priority. Furthermore, research is needed on how to fully utilize and convert energy resources during the control process.

[0003] Currently, the main engineering approach to wind and sand control along railway lines involves installing multiple sand barriers on the prevailing windward side of the line, based on the specific conditions at each work site, to effectively prevent sand from encroaching on the railway. While this method effectively controls sand, it wastes a significant amount of wind energy, and devices that combine sand control with wind power generation are extremely rare. There is an urgent need for a device that can protect railway lines from wind and sand damage while simultaneously making efficient use of wind resources. Summary of the Invention

[0004] The purpose of this invention is to provide a plate-type sand control and wind power generation combined device to improve the above-mentioned problems. To achieve the above objective, the technical solution adopted by this invention is as follows:

[0005] A plate-type sand control and wind power generation combined device includes:

[0006] Base;

[0007] A track pivot is provided above the base, and a pivot gear is provided on the track pivot.

[0008] A sand-proof wind turbine, wherein the sand-proof wind turbine is installed above the base and the lower end of the sand-proof wind turbine is fixedly connected to the track shaft;

[0009] An automatic rebound device is mounted on the base and connected to the sand-proof windproof plate.

[0010] A one-way rotating gear is disposed on one side of the track shaft and meshes with the shaft gear;

[0011] A transmission mechanism, wherein the transmission mechanism is connected to the one-way rotating gear;

[0012] A power generation component, which is connected to the transmission mechanism.

[0013] Optionally, the transmission mechanism includes an amplifying gear shaft, the diameter of which is at least twice the diameter of the unidirectional rotating gear.

[0014] Optionally, multiple sand-proof wind turbines are arranged side by side, with a one-way rotating gear connected below each sand-proof wind turbine, and the multiple one-way rotating gears are connected to the same amplifying gear shaft.

[0015] Optionally, the device also includes a dust cover, which surrounds the connection between the bottom of the sand-proof wind turbine and the base.

[0016] Optionally, the power generation assembly includes a planetary gearbox, a brake, a generator, and a transformer;

[0017] The transmission mechanism is connected to the planetary gear speed increaser via a connecting shaft. The planetary gear speed increaser is connected to the generator, and the generator is connected to the transformer via a cable.

[0018] Optionally, the output end of the planetary gear speed increaser is also provided with a brake.

[0019] Optionally, the sand-proof wind turbine panel includes balsa wood, fiberglass, and carbon fiber reinforced plastic, with balsa wood as the middle layer and carbon fiber reinforced plastic and fiberglass layers covering its two sides in sequence.

[0024] The beneficial effects of this invention are as follows:

[0025] The device provided by this invention integrates sand control and wind power generation. While the sand control wind turbine prevents sand from encroaching on the railway line, the wind energy generated by it causes the sand control wind turbine to swing and generate mechanical energy. This mechanical energy is then converted into electrical energy through a one-way rotating gear and a planetary gear speed increaser, thus achieving both sand control and wind power functions simultaneously. Furthermore, the one-way rotating gear prevents the gear from experiencing reverse resistance due to the back-and-forth swing of the sand control wind turbine, reducing energy waste and achieving high efficiency and reliability in power generation.

Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. The components of the embodiments of the present invention described and shown in the accompanying drawings can generally be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.

[0032] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0033] Currently, the main measures for sand hazard protection and control along railway lines in Northwest China involve constructing multiple high-rise sand barriers for engineering protection. These high-rise sand barriers consist of HDPE warp-knitted sand-blocking netting and angle steel columns. The column foundations are made of precast concrete, with HDPE netting suspended between the columns. Four binding holes are located at the top, and adjacent columns are connected diagonally with wire. The column spacing, netting height, and column foundation depth are selected based on actual conditions. While existing methods effectively control sandstorms, they waste a significant amount of wind energy, and devices combining sandstorm control with wind power generation are extremely rare.

[0034] This invention provides a novel combined device for wind and sand control and wind power generation along railway lines, which can protect railway lines from wind and sand damage while making more efficient use of wind resources and improving energy conversion.

[0035] Example 1

[0036] See Figure 1 This embodiment provides a plate-type sand control and wind power generation combination device, including: a base 1, a track shaft 6, a sand control and wind power plate 7, an automatic rebound device 5, a one-way rotating gear 3, a transmission mechanism 2, and a power generation component.

[0037] The track shaft 6 is located above the base 1, and a shaft gear is provided on the track shaft 6;

[0038] The sand-proof wind-powered plate 7 is set above the base 1, and the lower end of the sand-proof wind-powered plate 7 is fixedly connected to the track shaft 6.

[0039] The automatic rebound device 5 is mounted on the base 1 and connected to the sand-proof wind-powered plate 7;

[0040] The one-way rotating gear 3 is disposed on one side of the track shaft 6 and meshes with the shaft gear;

[0041] The transmission mechanism 2 is connected to the one-way rotating gear 3;

[0042] The power generation component is connected to the transmission mechanism 2.

[0043] See Figure 2 The wind acts on the sand-proof wind turbine 7, causing the sand-proof wind turbine 7 to swing back and forth (the sand-proof wind turbine 7 faces the prevailing wind direction in the local area). When each sand-proof wind turbine 7 swings forward, it drives the one-way gear at its lower part to rotate. The one-way rotating gear 3 drives the transmission mechanism 2 to move, which in turn drives the power generation component to operate, amplifying the rotation speed and cutting the magnetic field lines more quickly to generate electricity.

[0044] As an optional implementation, the transmission mechanism 2 includes an amplifying gear shaft, the diameter of which is at least twice the diameter of the unidirectional rotating gear 3.

[0045] Multiple sand-proof wind turbines 7 are arranged side by side, and a one-way rotating gear 3 is connected below each sand-proof wind turbine 7. The multiple one-way rotating gears 3 are connected to the same amplifying gear shaft.

[0046] The length of the central shaft of the amplifying gear shaft is preferably 3-6 times the length of a single sand-proof wind turbine plate 7, that is, 3-6 sand-proof wind turbine plates 7 are arranged side by side, with an amplifying gear shaft matched below them. Multiple driven gears are equidistantly arranged on the surface of the central shaft, and the number and position of the driven gears match the unidirectional rotating gear 3. When each wind turbine plate swings forward, it drives the unidirectional gear below it to rotate. After the unidirectional rotating gear 3 has worked, it concentrates the work done by all the unidirectional gears onto the amplifying gear shaft at the bottom in a relay manner.

[0047] As an optional implementation, the device further includes a dust cover 4, which surrounds the connection between the bottom of the sand and wind protection plate 7 and the base 1.

[0048] First, sand and dust prevention nets can be laid on both sides of the bottom of the wind turbine to ensure the normal operation of the wind turbine. Finally, dust cover 4 can be installed.

[0049] As an optional implementation, the power generation assembly includes a planetary gearbox 9, a brake 10, a generator 11, and a transformer 13;

[0050] The transmission mechanism 2 is connected to the planetary gear speed increaser 9 via the connecting shaft 8. The planetary gear speed increaser 9 is connected to the generator 11. The generator 11 is connected to the transformer 13 via the cable 12.

[0051] The rotation of the amplifying gear shaft is transmitted to the planetary gear speed increaser 9 through the connecting shaft 8. The planetary gear speed increaser 9 amplifies the rotation speed, and its output shaft is connected to the generator 11 through the connecting shaft 8, so that the generator 11 can cut the magnetic field lines more quickly to generate electricity.

[0052] As an optional implementation, the output end of the planetary gear speed increaser 9 is also equipped with a brake 10. When the wind is particularly strong, in order to ensure the safety of the equipment, the rotational speed is monitored at the output end (output shaft). When the rotational speed is higher than a set threshold, the brake 10 starts to work, limiting the high-speed rotation of the gear and preventing damage to the components due to high-intensity work.

[0053] As an optional implementation, the sand-proof wind turbine 7 includes balsa wood, fiberglass (glass fiber reinforced resin) and carbon fiber reinforced plastic, with balsa wood as the middle layer and carbon fiber reinforced plastic and fiberglass layers covering its two sides in sequence.

[0054] Balsa wood is a naturally lightweight material (density only 0.1-0.2 g / cm³). 3This design significantly reduces the weight of wind turbine panels, decreasing the load on the supporting structure and making it suitable for large panel designs. Furthermore, the porous structure effectively absorbs vibration energy, reducing fatigue stress caused by sandstorms or wind loads, and extending component lifespan.

[0055] Glass fiber reinforced resin has extremely strong weather resistance to salt, moisture and ultraviolet rays in sand and dust, making it suitable for desert / coastal environments and suitable as the surface layer of sand-proof wind turbine 7.

[0056] As an optional implementation, the bottom of the sand-proof wind turbine 7 is provided with a horizontal hollow cylinder, the track shaft 6 is fixedly inserted inside the horizontal hollow cylinder, and at least one end of the track shaft 6 is located outside the horizontal hollow cylinder.

[0057] The rotating shaft gear is located on the portion of the track shaft 6 outside the transverse hollow cylinder. The rotating shaft gear meshes with the unidirectional rotating gear 3 below.

[0058] As an optional implementation, the automatic rebound device 5 is a torsion spring or spring, and is located on both the front and rear sides of the sand-proof wind turbine 7. When the sand-proof wind turbine 7 swings backward, the unidirectional rotating gear 3 has an anti-rebound device inside, preventing the gear from generating a reverse rotational force due to the backward swing of the sand-proof wind turbine 7, thus making the device operate more efficiently. When the natural wind stops, the sand-proof wind turbine 7 gradually returns to its original position through the automatic rebound device 5 at the bottom. To ensure safety and considering the safety and durability of the wind turbine, the track shaft 6 is configured to allow rotation within a range of 80°-100° with respect to the horizontal plane.

[0059] As an optional implementation, the lower part of the base 1 is buried underground, the upper part of the base 1 protrudes 15-25cm above the ground, and the upper part of the base 1 is provided with a mounting groove for installing the transmission mechanism 2.

[0060] Specifically, the base 1 is made of C25 concrete and is rectangular in shape, 150cm long, 30cm wide, and 85cm high. It is buried 65cm underground and has a 20cm high platform above the ground for installing the transmission mechanism 2 and supporting the sand-proof wind turbine plate 7, unidirectional rotating gear 3, and other components.

[0061] The specific construction plan for the device of the present invention is as follows:

[0062] Step 1: After the concrete base 1 is poured, install the enlarged gear shaft, the one-way rotating gear 3 and the track shaft 6 in sequence from low to high on the upper part of the base 1. Based on the actual site conditions, set the one-way rotating gear 3 and set the windward direction as the working direction.

[0063] Step 2: Install the prefabricated high-strength sand-proof wind turbine plate 7 on the track shaft 6, and connect the plate to the automatic rebound device 5 to ensure that it can automatically return to its original position after rotation. Then, install sand-proof and dust-proof nets on both sides of the bottom of the wind turbine plate, and finally install the dust cover 4.

[0064] Step 3: Install the connecting shaft 8 on one side of the wind turbine panel, and install the planetary gear speed increaser 9, brake 10, generator 11 and transformer 13 in sequence from the end near the wind turbine panel to the far end. Connect the generator 11 to the transformer 13 through the cable 12.

[0065] This invention provides a novel device that integrates sand control and wind power generation. While the wind turbines prevent sand from encroaching on railway lines, the resulting wind energy causes the turbines to oscillate, generating mechanical energy. This mechanical energy is then converted into electrical energy through a one-way rotating gear 3 and a planetary gear speed increaser 9, thus simultaneously achieving sand control and wind power generation. Furthermore, the one-way rotating gear 3 prevents the gears from experiencing reverse resistance due to the turbines' oscillation, reducing energy waste and achieving high efficiency and reliability in power generation. Compared to previous power generation devices, this invention offers lower economic costs, a smaller overall size for easier transportation, and easier maintenance and repair. Installation is also simpler, saving time and effort.

[0066] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be determined by the scope of the claims.
