Description

Technical Field

[0001] This invention belongs to the field of wind-powered heating, and particularly relates to a wind-powered heating device based on rural farms. Background Technology

[0002] Currently, wind power heating in my country includes liquid stirring heating, solid friction heating, liquid extrusion heating, and eddy current heating.

[0003] Liquid agitation heating involves connecting an agitator rotor, equipped with blades, to the shaft of a blower. The rotor is placed inside an agitator tank filled with liquid; the tank's inner wall is slab-like and also equipped with blades. As the rotor moves the blades, the liquid vortexes between the stator blades, continuously impacting them, thus slowly heating the liquid and generating the desired heat energy. This method can operate at any wind speed, is relatively safe and convenient, and involves minimal wear.

[0004] The rotor of a solid friction-heated wind turbine rotates, and a set of braking elements is installed on the rotor shaft. Utilizing the principle of centrifugal force, the braking elements rub against a solid surface. The heat generated by this friction heats the oil, and then a water jacket transfers the heat away, thus obtaining the desired heat. This method is relatively simple, but the key lies in the material of the braking elements; a suitable wear-resistant material must be selected. Domestic tests using ordinary car brake pads as braking elements show that they need to be replaced after approximately 300 hours of operation, indicating excessively rapid wear.

[0005] This method of heating liquid by compression utilizes a hydraulic pump and a damping orifice. When the wind turbine drives the hydraulic pump, it pressurizes the liquid working fluid (usually oil), generating hydraulic pressure through mechanical energy. A multi-pronged approach forces the pressurized working fluid to be ejected at high speed from a narrow damping orifice, rapidly impacting the liquid in the tailpipe behind the orifice. This causes high-speed impact and friction between liquid molecules, generating heat. This method also avoids component wear and is relatively reliable.

[0006] Eddy current heating relies on a wind turbine shaft driving a rotor. A magnetizing coil is installed between the rotor's outer edge and the stator. When a weak current passes through the magnetizing coil, magnetic field lines are generated. When the rotor is placed down, it cuts these magnetic field lines, creating eddy currents and generating heat between the stator and rotor. This is eddy current heating. To prevent damage to the magnetizing coil, a ring-shaped cooling water jacket is added around the stator to continuously remove the heat, thus providing the desired hot water. This heating process is primarily mechanical, consuming very little electricity. Furthermore, it draws DC power from batteries charged by the wind turbine, resulting in a higher energy conversion efficiency compared to electric heating.

[0007] While eddy current heating technology exists, it requires high wind speeds and power. At low wind speeds, the fan doesn't rotate or rotates too slowly, failing to generate effective heat. Eddy current heating relies on a wind turbine shaft driving a rotor. A magnetized coil is installed between the rotor's outer edge and the stator. When a weak current passes through the magnetized coil, magnetic lines of force are generated. When the rotor is positioned, it cuts these magnetic lines of force, creating eddy currents and generating heat between the stator and rotor. This is eddy current heating. The rotation of the wind turbine blades drives the acceleration gear, which in turn drives the rotor of an alternating current generator. In the alternating current generator, the rotor consists of magnetic poles, a rotor shaft, and an iron core. The magnetic poles are fixed to the rotor and rotate with it as the rotor rotates. The stator consists of an iron core and windings connected to end rings. When the magnetic poles rotate on the rotor shaft, the relative motion between the rotor and stator causes the magnetic field to pass through the stator windings, generating an alternating current in the windings. Alternating current passing through an enameled coil forms a closed loop, generating an alternating magnetic field within the coil. When an iron water container is placed in this alternating magnetic field, the material's conductivity induces eddy currents within the metal. These eddy currents, influenced by resistance and internal friction, are converted into heat energy, heating the metal. This heating method is characterized by rapid heating, high efficiency, and ease of operation. This heating process primarily involves mechanical transfer; the magnetized coil consumes very little electricity, and DC power can be obtained from a wind-powered battery. Therefore, unlike electric heating, wind energy conversion efficiency is higher.

[0008] Although eddy current heating technology already exists, the existing technology has high requirements for wind speed and force. At low wind speeds, the fan does not rotate or rotates slowly, and cannot effectively generate heat. Summary of the Invention

[0009] This invention proposes a wind-powered heating device for rural farms, which uses a biogas CNG engine to assist the fan blades in driving an alternating current generator to generate electricity and heat, thus solving the above-mentioned problems.

[0010] To achieve the above objectives, the present invention adopts the following technical solution:

[0011] A wind-powered heating device for rural farms includes an alternating current generator and an enameled coil electrically connected to the alternating current generator. It also includes wind turbine blades that drive the alternating current generator to generate electricity. The wind turbine blades are vertically mounted on the top of a rotating shaft. A drive bevel gear is mounted on the rotating shaft. The drive bevel gear is meshed with a first transmission rod. The first transmission rod is meshed with an acceleration gear set via a spur gear. The acceleration gear set is meshed with the rotor of the alternating current generator via a spur gear and drives the alternating current generator to rotate and generate electricity. The device also includes a CNG (common gas) engine that can drive the alternating current generator to generate electricity.

[0012] Preferably, the front end of the first transmission rod meshes with the driving bevel gear through a driven bevel gear, and the end is provided with a spur gear for connecting to the biogas CNG engine. The output end of the biogas CNG engine is also provided with a spur gear and is connected to the spur gear at the end of the first transmission rod through a transmission belt, so that the biogas CNG engine can drive the alternating current generator to generate electricity.

[0013] Preferably, the biogas CNG engine is equipped with a biogas intake pipe that is connected to the biogas digester outlet.

[0014] Preferably, the lower end of the rotating shaft is rotatably connected to the base via a bearing, the active bevel gear is located at the bottom of the blower blades, and the active bevel gear is connected to the biogas digester stirring device via a second transmission rod.

[0015] Preferably, both ends of the second transmission rod are provided with driven bevel gears, and a connecting rod mechanism is provided between the two driven bevel gears. The second transmission rod consists of two rods, left and right, which are connected or disconnected through the connecting rod mechanism.

[0016] Preferably, the biogas digester stirring device includes a stirring blade at the bottom, a vertical rod disposed at the upper end of the stirring blade, and a conical driven gear disposed at the top of the vertical rod, wherein the stirring blade is located inside the biogas digester.

[0017] Preferably, the linkage mechanism includes a left connecting cylinder and a right connecting cylinder, which are respectively connected to the left and right rods of the second transmission rod. An electromagnet is installed on the inner wall of the left connecting cylinder along its axial direction. Two conductive rings are provided on the outer wall of the left connecting cylinder. The two conductive rings are respectively the positive and negative terminals of the power supply and are electrically connected to the positive and negative terminals of the electromagnet power supply line. A conductive seat is provided at the bottom of the left connecting cylinder. The bottom of the conductive seat is installed on the ground by a plastic bracket. Two arc-shaped elastic conductive plates are provided on the conductive seat. The ends of the two arc-shaped elastic conductive plates are respectively electrically connected to the positive and negative terminals of the external power supply line. The arc-shaped portions in the middle of the two arc-shaped elastic conductive plates are elastically fitted to the two conductive rings.

[0018] The inner cavity of the right connecting cylinder is provided with three sliding grooves evenly distributed along its circumference. The inner cavity of the right connecting cylinder is fitted with a movable docking rod made of magnetic metal. The outer wall of the movable docking rod is provided with three semi-cylinders evenly distributed along its circumference. The three semi-cylinders cooperate with the three sliding grooves respectively, so that the movable docking rod can slide along the length of the three sliding grooves through the three semi-cylinders and can rotate synchronously with the right connecting cylinder. The inner wall of the right connecting cylinder and the rear wall of the movable docking rod are directly connected by a spring. The inner diameter of the left connecting cylinder is larger than the sum of the outer diameters of the movable docking rod and the semi-cylinders, so that the movable docking rod and the semi-cylinders can extend into the left connecting cylinder.

[0019] When the electromagnet is energized, it generates magnetic force. Under the attraction of the electromagnet, the three semi-cylinders on the outer wall of the movable docking rod move along the three sliding grooves towards the electromagnet, eventually making the movable docking rod tightly attracted to the electromagnet, causing the left connecting cylinder and the right connecting cylinder to rotate synchronously.

[0020] After the movable docking rod is tightly attracted to the electromagnet, the rear section of the three semi-cylinders on its outer wall is still located in the three sliding grooves, generating friction that can cause the right connecting cylinder to drive the movable docking rod and the electromagnet to rotate synchronously, thereby driving the left connecting cylinder and the right connecting cylinder to rotate synchronously.

[0021] After the electromagnet is de-energized, the movable connecting rod retracts completely into the right connecting cylinder under the spring tension, thereby disconnecting the left and right connecting cylinders.

[0022] Preferably, the alternating current generator and the enameled coil are electrically connected via an alternating current negative line and an alternating current positive line.

[0023] Preferably, a shaft gear is fitted at the bottom of the shaft, a speed sensor is provided on the base, and a synchronizing gear at the top of the speed sensor meshes with the shaft gear;

[0024] It also includes a wind speed sensor, which is installed at a height higher than the wind turbine blades;

[0025] The output end of the biogas CNG engine consists of two drive shafts, which are connected and disconnected by an electromagnetic clutch.

[0026] Preferably, it also includes a PLC intelligent control system, wherein the input terminal of the PLC intelligent control system is electrically connected to the output terminal of the speed sensor and the output terminal of the wind speed sensor, respectively, and the output terminal of the PLC intelligent control system is electrically connected to the input terminal of the electromagnetic clutch, the input terminal of the linkage mechanism and the input terminal of the biogas CNG engine's own control system, respectively.

[0027] The beneficial effects of this invention are:

[0028] The present invention includes an alternating current generator and an enameled coil electrically connected to the alternating current generator, and also includes a fan blade for driving the alternating current generator to generate electricity. The fan blade is vertically arranged at the top of a rotating shaft. A drive bevel gear is arranged on the rotating shaft. The drive bevel gear is meshed with a first transmission rod. The first transmission rod is meshed with an acceleration gear set through a spur gear. The acceleration gear set is meshed with the rotor of the alternating current generator through a spur gear and drives the alternating current generator to rotate and generate electricity. The invention also includes a biogas CNG engine that can drive the alternating current generator to generate electricity.

[0029] The speed sensor of this invention transmits the rotational speed of the fan blade 1 to the PLC intelligent control system in real time. When the speed sensor detects that the fan blade 1's rotational speed is low, the PLC intelligent control system controls the biogas CNG engine's own control system to increase its air intake, thereby increasing its output kinetic energy and improving the output power of the alternating current generator. As the fan blade 1's rotational speed increases, the biogas CNG engine's air intake decreases, causing it to idle and stop supplying kinetic energy to the alternating current generator. When the wind speed is high, the biogas CNG engine can stop working, avoiding energy waste and machine wear.

[0030] When the wind speed sensor of this invention detects a wind speed of less than 12.0 m / s, the wind turbine blades cannot work effectively and cannot effectively drive the alternating current generator to generate electricity. Biogas is introduced into the biogas CNG engine, which drives the alternating current generator to rotate and generate electricity. The generated current supplies the enameled coil. When the current flows through the enameled coil, the electric field generates a changing magnetic field. The changing magnetic field generates eddy currents between itself and the iron water storage device above the enameled coil, which heats the water. The heated water is used to provide heating for the farm.

[0031] When the wind speed sensor of this invention detects a wind speed greater than 12.0 m / s, in order to ensure that the rotor speed of the alternating current generator is constant, the PLC intelligent control system supplies power to the linkage mechanism 6. The linkage mechanism connects the second transmission rod to drive the biogas digester stirring device to stir the biogas digester, thereby accelerating the production of biogas. The biogas produced can also be used by farmers for other purposes, making it suitable for widespread promotion. Attached Figure Description

Detailed Implementation

[0046] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments.

[0047] Reference Figure 1-12 A wind-powered heating device for rural livestock farms includes a PLC intelligent control system, an alternating current generator 8, and an enameled coil 9 electrically connected to the alternating current generator 8. The alternating current generator 8 and the enameled coil 9 are electrically connected via an alternating current negative wire 14 and an alternating current positive wire 15. It also includes wind turbine blades 1 that drive the alternating current generator 8 to generate electricity. The wind turbine blades 1 are 2.4m long and 1.0m in diameter, and are made of fiberglass or corrosion-resistant aluminum alloy. The drive method is direct drive, and the rated speed is 300r / min. The design wind speed is 1.0m / s, the cut-in wind speed is 1.5m / s, and the rated wind speed is 12.0m / s.

[0048] The wind turbine blades 1 are vertically mounted on the top of the rotating shaft 2. A driving bevel gear 3 is mounted on the rotating shaft 2, and the driving bevel gear 3 is meshed with a first transmission rod 4. The first transmission rod 4 is meshed with an acceleration gear set 7 via a spur gear. The acceleration gear set 7 is meshed with the rotor of an alternating current generator 8 via a spur gear and drives the alternating current generator 8 to rotate and generate electricity. The system also includes a biogas CNG engine 10 that can drive the alternating current generator 8 to generate electricity. When the wind speed is below 12.0 m / s, the biogas CNG engine 10 is started to supplement kinetic energy and maintain a constant speed for the alternating current generator 8. The front end of the first transmission rod 4 meshes with the driving bevel gear 3 via a driven bevel gear, and the end is equipped with a spur gear for connecting to the biogas CNG engine 10. The output end of the biogas CNG engine 10 is also equipped with a spur gear and is connected to the spur gear at the end of the first transmission rod 4 via a transmission belt 11, enabling the biogas CNG engine 10 to drive the alternating current generator 8 to generate electricity. The biogas CNG engine 10 is equipped with a biogas inlet pipe 101 that is connected to the biogas digester outlet.

[0049] The lower end of the rotating shaft 2 is rotatably connected to the base 13 via a bearing. The driving bevel gear 3 is located at the bottom of the blower blade 1. The driving bevel gear 3 is connected to the biogas digester stirring device 12 via the second transmission rod 5. Both ends of the second transmission rod 5 are provided with driven bevel gears. A linkage mechanism 6 is provided between the two driven bevel gears. The second transmission rod 5 consists of two rods, left and right, which are connected or disconnected by the linkage mechanism 6. The linkage mechanism 6 includes a left connecting cylinder 61 and a right connecting cylinder 62, which are respectively connected to the left and right rods of the second transmission rod 5. An electromagnet 63 is installed on the inner wall of the left connecting cylinder 61 along its axial direction. Two conductive rings 64 are provided on the outer wall of the left connecting cylinder 61. The two conductive rings 64 are the positive and negative terminals of the power supply, respectively, and are electrically connected to the positive and negative terminals of the power supply line of the electromagnet 63. A conductive seat 65 is provided at the bottom of the left connecting cylinder 61. The bottom of the conductive seat 65 is installed on the ground via a plastic bracket. Two arc-shaped elastic conductive rings are provided on the conductive seat 65. Two arc-shaped elastic conductive sheets 66 have their ends electrically connected to the positive and negative terminals of an external power supply line, respectively. The curved portions of the two arc-shaped elastic conductive sheets 66 are elastically fitted to two conductive rings 64. The inner cavity of the right connecting cylinder 62 has three evenly distributed sliding grooves 621. A movable docking rod 67 made of magnetic metal is fitted inside the inner cavity of the right connecting cylinder 62. Three semi-cylinders 68 are evenly distributed along the outer wall of the movable docking rod 67. The three semi-cylinders 68 cooperate with the three sliding grooves 621, allowing the movable docking rod 67 to pass through the three semi-cylinders 68 along the three sliding grooves. The groove 621 slides along its length and can rotate synchronously with the right connecting cylinder 62. The inner wall of the right connecting cylinder 62 and the rear wall of the movable docking rod 67 are directly connected by a spring 69. The inner diameter of the left connecting cylinder 61 is larger than the sum of the outer diameters of the movable docking rod 67 and the semi-cylinder 68, so that the movable docking rod 67 and the semi-cylinder 68 can extend into the left connecting cylinder 61. When the electromagnet 63 is energized, it generates magnetic force. Under the attraction of the electromagnet 63, the three semi-cylinders 68 on the outer wall of the movable docking rod 67 move along the three grooves 621 toward the electromagnet 63, eventually causing the movable docking rod 67 to engage with the electromagnet. The tight engagement of iron 63 causes the left connecting cylinder 61 and the right connecting cylinder 62 to rotate synchronously. After the movable docking rod 67 is tightly engaged with the electromagnet 63, the rear sections of the three semi-cylinders 68 on its outer wall remain within the three sliding grooves 621, generating friction that allows the right connecting cylinder 62 to drive the movable docking rod 67 and the electromagnet 63 to rotate synchronously, thereby driving the left connecting cylinder 61 and the right connecting cylinder 62 to rotate synchronously. After the electromagnet 63 is de-energized, the movable docking rod 67 retracts completely into the right connecting cylinder 62 under the tension of the spring 69, thereby disconnecting the left connecting cylinder 61 and the right connecting cylinder 62. A rotating shaft gear 21 is fitted at the bottom of the rotating shaft 2, and a speed sensor 16 is installed on the base 13. The synchronous gear at the top of the speed sensor 16 meshes with the rotating shaft gear 21. The rotating shaft 2 rotates synchronously with the fan blades 1, thereby driving the rotating shaft gear 21 to rotate synchronously. The rotating shaft gear 21 drives the synchronous gear at the top of the speed sensor 16 to rotate, thus enabling the speed sensor 16 to detect the speed of the fan blades 1 in real time.

[0050] The speed sensor 16 transmits the rotational speed of the blower blades 1 to the PLC intelligent control system in real time. When the speed sensor 16 detects that the speed of the blower blades 1 is low, the PLC intelligent control system controls the biogas CNG engine 10 to increase its air intake, thereby increasing its output kinetic energy and improving the output power of the alternating current generator 8. As the speed of the blower blades 1 increases, the air intake of the biogas CNG engine 10 is reduced, causing the biogas CNG engine 10 to idle and stop providing kinetic energy to the alternating current generator 8. When the wind speed is high, the biogas CNG engine 10 can stop working to avoid wasting energy and damaging the machine.

[0051] It also includes a wind speed sensor, which is installed at a height higher than the fan blades 1 to prevent the rotation of the fan blades 1 from affecting the accuracy of the wind speed sensor. The wind speed sensor transmits the detected wind speed to the PLC intelligent control system in real time.

[0052] The output end of the biogas CNG engine 10 consists of two drive shafts, which are connected and disconnected by an electromagnetic clutch 17.

[0053] The input terminals of the PLC intelligent control system are electrically connected to the output terminals of the speed sensor 16 and the wind speed sensor, respectively. The output terminals of the PLC intelligent control system are electrically connected to the input terminals of the electromagnetic clutch 17, the linkage mechanism 6, and the biogas CNG engine 10's own control system. The input terminals of the PLC intelligent control system are connected to the output terminals of the alternating current generator 8, which can detect the output power of the alternating current generator 8 in real time. The biogas digester stirring device 12 includes a stirring blade 121 at the bottom, a vertical rod 122 set at the upper end of the stirring blade 121, and a conical driven gear set at the top of the vertical rod 122. The stirring blade 121 is located inside the biogas digester.

[0054] When the wind speed sensor detects a wind speed greater than 12.0 m / s, the PLC intelligent control system supplies power to the linkage mechanism 6, which controls the second transmission rod 5 to drive the biogas digester stirring device 12 to stir the biogas digester and increase the biogas output.

[0055] In addition, the lower the wind speed, the greater the kinetic energy provided by the biogas CNG engine 10 controlled by the PLC intelligent control system. When the wind speed reaches 12.0 m / s, the PLC intelligent control system cuts off the power to the electromagnetic clutch 17, disconnects the two drive shafts at the output end of the biogas CNG engine 10, and puts the biogas CNG engine 10 in an idling state, stopping the supply of kinetic energy to the alternating current generator 8.

[0056] The fan blades 1 rotate under the wind, driving the active bevel gear 3 to rotate. The active bevel gear 3 drives the first transmission rod 4 to rotate. The first transmission rod 4 drives the alternating current generator 8 to rotate and generate electricity through the gear. The alternating current generator 8 supplies power to the enameled coil 9 through the alternating current negative line 14 and the alternating current positive line 15. When the current flows through the enameled coil, the electric field generates a changing magnetic field. The changing magnetic field generates eddy currents between itself and the iron water storage device above the enameled coil, which heats the water. The heated water is used to provide heating for the aquaculture farm.

[0057] When the wind speed sensor detects a wind speed of less than 12.0 m / s, the wind turbine blades 1 cannot work effectively and cannot effectively drive the alternating current generator 8 to generate electricity. Instead, biogas is introduced into the biogas CNG engine 10. The spur gear at the output end of the biogas CNG engine 10 drives the transmission belt 11 to drive the first transmission rod 4 to rotate, which in turn drives the alternating current generator 8 to rotate and generate electricity. In addition, the lower the wind speed, the greater the kinetic energy provided by the biogas CNG engine 10 controlled by the PLC intelligent control system.

[0058] When the wind speed sensor detects a wind speed greater than 12.0 m / s, in order to ensure that the rotor speed of the alternating current generator 8 is constant, the PLC intelligent control system supplies power to the linkage mechanism 6. The linkage mechanism 6 connects the second transmission rod 5 to drive the biogas digester stirring device 12 to stir the biogas digester, thereby accelerating the production of biogas. The biogas produced can also be used by farmers for other purposes, making it suitable for widespread promotion.

[0059] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.

Under the attraction of the electromagnet (63), the three semi-cylinders (68) on the outer wall of the movable docking rod (67) move along the three sliding grooves (621) towards the electromagnet (63), eventually making the movable docking rod (67) tightly attracted to the electromagnet (63), causing the left connecting cylinder (61) and the right connecting cylinder (62) to rotate synchronously. After the movable docking rod (67) and the electromagnet (63) are tightly attracted, the rear section of the three semi-cylinders (68) on its outer wall is still located in the three sliding grooves (621) to generate friction, which can drive the right connecting cylinder (62) to drive the movable docking rod (67) and the electromagnet (63) to rotate synchronously, thereby driving the left connecting cylinder (61) and the right connecting cylinder (62) to rotate synchronously. After the electromagnet (63) is de-energized, the movable docking rod (67) is fully retracted into the right connecting cylinder (62) under the tension of the spring (69), thereby disconnecting the left connecting cylinder (61) and the right connecting cylinder (62).
