Description

Technical Field

[0001] The utility model relates to the field of irrigation, in particular to a power-free water-lifting irrigation device for mine ecological restoration. Background Art

[0002] Mine ecological restoration mainly refers to the ecological restoration and comprehensive management of closed mines after production stops. This kind of restoration often supplements artificial measures while relying on the self-recovery of the ecosystem to accelerate the ecological restoration process or rebuild a new ecological environment. The artificial measures generally involve planting vegetation in the developed mining areas to achieve vegetation reclamation before development. And the newly planted vegetation needs to be watered regularly and with artificial intervention to improve the survival rate. However, after the mine is closed, the corresponding power facilities are also removed, and most mines are located in remote areas without power supply. The irrigation of these vegetation has become a problem. Relying solely on manual water lifting and watering, the labor cost is too high, and the mine terrain is uneven, making manual handling difficult and risky. Therefore, there is a need for a power-free power generation irrigation device to accelerate the restoration of the mine ecological system. Content of the Utility Model

[0003] Aiming at the defects in the prior art, to replace manual watering, reduce labor costs, and accelerate the restoration of the mine ecological system. The utility model provides a power-free water-lifting irrigation device for mine ecological restoration, which includes a water wheel, a fixed pile, a drainage trough, and a generator; the water wheel is provided with a plurality of scraping plates, all the scraping plates are evenly distributed along the circumferential direction of the water wheel, and each scraping plate is provided with a water bucket or some scraping plates are provided with water buckets; the fixed pile is installed near the water falling point of the mine water flow, the water wheel is rotationally installed on the fixed pile through a rotating shaft, and the water falling point is located on the blade of the water wheel for driving the water wheel to rotate; the generator is installed at the upper end of the fixed pile, and the input shaft of the generator is in transmission connection with the rotating shaft; the upper end of the drainage trough is fixedly connected above the fixed pile and is located on one side of the water wheel, and the water flow drives the water wheel and the generator to rotate, so that the water bucket transfers the water in the water channel directly below to the drainage trough.

[0004] The beneficial effects of the utility model are as follows:

[0005] 1. The main power of the water wheel comes from the water flow impacting the scraping plates of the water wheel, and the lower end of the water wheel is also in the water flow. The flowing water pushes the scraping plates, generating another part of the power to drive the water wheel. With dual power, the rotation speed of the water wheel is relatively fast, and the frequency of taking water and pouring water in turn increases, improving the efficiency of transferring water. Using the drainage trough to transfer water to the vegetation that needs irrigation can improve the survival rate and growth of the vegetation, which is beneficial to accelerating the restoration of the mine ecological system.

[0006] 2. When the water wheel rotates, it also drives the generator to rotate. The electricity generated by the generator is stored in the battery, and the battery drives the water pump to irrigate the vegetation above the ditch, increase the irrigation area, and further accelerate the restoration of the mine ecosystem.

[0007] Preferably, the upper end of the drainage trough is fixed above the fixing pile by a bracket, and the bracket is provided with a baffle covering the generator. The baffle can prevent the generator from contacting with water and ensure the normal operation of the generator. In addition, in order to reinforce the drainage trough, the middle part of the drainage trough is fixedly connected to the side of the fixing pile by a fixing rod.

[0008] Preferably, the input shaft is connected to the rotating shaft via a belt transmission assembly. The belt transmission assembly includes a first pulley, a second pulley and a belt; the first pulley is coaxially fixed to the input shaft, the second pulley is coaxially fixed to the rotating shaft, and the belt is sleeved on the first pulley and the second pulley. The diameter of the first pulley is smaller than the diameter of the second pulley, and the first pulley and the second pulley form a speed-increasing belt transmission to increase the rotation speed of the generator and increase the power generation.

[0009] Preferably, the generator is installed on the upper end of the fixed pile through the base. The upper end of the fixed pile is provided with a trough adapted to the base, and the bottom wall of the trough is connected to the base through an electric telescopic cylinder, and the electric telescopic cylinder drives the motor to rise and fall to control the tightness of the belt. Specifically, three electric telescopic cylinders are provided, and the three electric telescopic cylinders are distributed in a triangle between the bottom wall of the trough and the base. Since the water flow in some mines will change accordingly with the increase or decrease of rainfall, in the rainy season, there is a lot of rain and a large amount of water, and the power to drive the water wheel is sufficient. In this case, the three telescopic motors are extended to the highest point, and the belts are clamped with the first pulley and the second pulley respectively, and the water wheel drives the generator to generate electricity. If it is not in the rainy season, the three telescopic motors are retracted to the lowest point, the friction between the belt and the first pulley and the second pulley is reduced, the belt is loose but not falling off, and the water wheel cannot drive the generator to generate electricity, so as to avoid the water wheel from stopping due to excessive load, and does not affect the water bucket to transfer water.

[0010] Preferably, the lower part of the drainage trough is lower than the center of the water wheel. Water in the drainage trough needs to flow down by gravity, and the drainage trough can only irrigate vegetation at a lower position, so it needs to be lower than the center of the water wheel.

In all the drawings, similar elements or parts are generally identified by similar reference numerals. In the drawings, each element or part is not necessarily drawn according to the actual scale.

Specific Embodiment

[0014] Hereinafter, embodiments of the technical solution of the present invention will be described in detail with reference to the drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and thus are only examples and cannot be used to limit the protection scope of the present invention.

[0015] It should be noted that unless otherwise specified, the technical terms or scientific terms used in this application should have the ordinary meaning understood by those skilled in the art to which the present invention belongs.

[0016] As Figure 1 shown, this embodiment provides a power-free water-lifting irrigation device for mine ecological restoration, including a water wheel 1, a fixed pile 2, a drainage trough 3, and a generator 4. Among them, the water wheel 1 is provided with a plurality of scrapers 5. The number of scrapers 5 is not limited and depends on the diameter of the water wheel 1, but all the scrapers 5 are evenly distributed along the circumference of the water wheel 1. Each scraper 5 is provided with a water bucket 6 or some of the scrapers 5 are provided with water buckets 6.

[0017] In this embodiment, the fixed pile 2 is installed near the water falling point of the mine water flow, such as a water flow with a certain drop. The fixed pile 2 is installed on the left or right side of the water falling point. The water wheel 1 is rotatably installed on the fixed pile 2 through a rotating shaft 7, and the water falling point is located on the blade of the water wheel 1. In order to reduce the frictional resistance, a bearing needs to be installed between the rotating shaft 7 and the fixed pile 2. The upper end of the drainage trough 3 is fixedly connected above the fixed pile 2 and is located on one side of the water wheel 1. Specifically, the upper end of the drainage trough 3 is fixed to the fixed pile 2 through a bracket 8. In order to reinforce the drainage trough 3, the middle of the drainage trough 3 is fixedly connected to the side of the fixed pile 2 through a fixed rod 9.

[0018] In this embodiment, the lower part of the drainage trough 3 is lower than the center of the water wheel 1. The main power of the water wheel 1 comes from the water flow hitting the scraper 5 of the water wheel 1, and the lower end of the water wheel 1 is also located in the water flow. The water flow moves and pushes the scraper 5, generating another part of the power to drive the water wheel 1. With dual power, the rotation speed of the water wheel 1 is relatively fast, and the frequency of alternately taking water and pouring water increases, improving the efficiency of transferring water. The drainage trough 3 is used to transfer water to the vegetation that needs irrigation, improving the survival rate and growth of the vegetation, and is beneficial to accelerating the restoration of the mine ecological system.

[0019] If the planted vegetation is higher than the water wheel 1, a water pump is required to pump water to a higher place, and electricity is needed as the energy source. To solve this problem, in this embodiment, the generator 4 is installed at the upper end of the fixed pile 2, and the bracket 8 is provided with a baffle 10 that covers the generator 4. The baffle 10 can prevent the generator 4 from coming into contact with water and ensure the normal operation of the generator 4.

[0020] In this embodiment, the input shaft of the generator 4 is in transmission connection with the rotating shaft 7. Specifically, the input shaft and the rotating shaft 7 are in transmission connection through a belt transmission assembly. The belt transmission assembly includes a first pulley 11, a second pulley 12 and a belt 13; the first pulley 11 is coaxially fixed with the input shaft, the second pulley 12 is coaxially fixed with the rotating shaft 7, and the belt 13 is sleeved on the first pulley 11 and the second pulley 12. The diameter of the first pulley 11 is smaller than that of the second pulley 12, and the first pulley 11 and the second pulley 12 form a speed-increasing belt transmission to increase the rotation speed of the generator 4 and increase the power generation.

[0021] In addition, the water flow formed by the mine depends on the rainfall. In the case of a small water flow, the power to drive the water wheel 1 is small and cannot drive the generator 4 to rotate. To solve this problem, in this embodiment, the generator 4 is installed at the upper end of the fixed pile 2 through a base 16. The upper end of the fixed pile 2 is provided with a sunk groove 14 adapted to the base 16, and the bottom wall of the sunk groove 14 and the base 16 are connected through an electric telescopic cylinder 15, and the motor is driven to lift by the electric telescopic cylinder 15 to control the tightness of the belt 13. Specifically, there are three electric telescopic cylinders 15, and the three electric telescopic cylinders 15 are distributed in a triangle between the bottom wall of the sunk groove 14 and the base 16. Since part of the water flow in the mine will change correspondingly with the increase and decrease of the rainfall, during the rainy season, there is more rain and a large amount of water, and the power to drive the water wheel 1 is sufficient. In this case, the three telescopic motors extend to the highest position, and the belt 13 is respectively clamped with the first pulley 11 and the second pulley 12, and the water wheel 1 drives the generator 4 to generate electricity. If it is in the non-rainy season, the three telescopic motors retract to the lowest point, the friction between the belt 13 and the first pulley 11 and the second pulley 12 decreases, the belt 13 is loose but does not fall off, and the water wheel 1 cannot drive the generator 4 to generate electricity, avoiding the water wheel 1 from stopping due to excessive load and not affecting the water bucket 6 to transfer water.

[0022] According to the above solution, after solving the power generation problem, it is also necessary to configure a storage battery, a voltage stabilizing circuit, a charging circuit, etc. near the water wheel 1. After the generator 4 generates electricity, it charges the storage battery through the voltage stabilizing circuit and the charging circuit. Then, an electric water pump adapted to the voltage of the storage battery is selected. The electric water pump can irrigate the vegetation whose position is higher than the water ditch, increasing the irrigation area and further accelerating the restoration of the mine ecosystem. In addition, the electric telescopic cylinder 15 in this embodiment is equipped with a corresponding controller. The input end of the controller is electrically connected to the storage battery, and the output end is electrically connected to the three electric telescopic cylinders 15. The controller is provided with an "extend button" and a "retract button". When the retract button is manually pressed, the controller makes the three telescopic motors retract synchronously. On the contrary, when the extend button is pressed, the controller makes the three telescopic motors extend synchronously, thereby controlling the tightness of the belt 13.

[0023] Finally, it should be noted that: the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it; although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that: they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements on some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present invention, and they should all be covered by the scope of the claims and the description of the present invention.
