[0001] The present invention relates to the technical field of energy regeneration, in particular to a renewable energy system and a working method for supplying electricity to buildings. Background Art

[0002] Wind power generation system is another common building renewable energy system. Wind power generation system can collect wind energy by setting up wind turbines on the roof or near the building, and convert it into electricity for building use.

[0003] Existing power supply buildings have many vents around them to provide ventilation and heat dissipation for the internal power equipment, and blow cold air into the building according to the external wind direction, but this part of the wind power is often directly wasted and cannot be recycled or efficiently recycled. Therefore, it is necessary to design a renewable energy system for power supply buildings with high energy utilization. Summary of the invention

[0004] The object of the present invention is to provide a renewable energy system for supplying electricity to buildings, so as to solve the problems raised in the above background technology.

[0005] In order to solve the above technical problems, the present invention provides the following technical solutions: a renewable energy system for power supply buildings, comprising a building body, a plurality of vents being evenly arranged on the side walls of the building body, and a wind recovery device and a working method being arranged inside the vents.

[0006] According to the above technical solution, the wind recovery device includes a mounting ring, and the upper and lower inner walls of the vent are correspondingly fixed with longitudinal plates by welding. One end of the longitudinal plate is connected with an extension plate by welding. The mounting ring is slidably clamped between the two extension plates, and the mounting ring is rotatable. The outer wall of the mounting ring is evenly distributed with wind blades in a circular shape.

[0007] According to the above technical solution, a connecting rod is evenly fixed to the inner wall of the mounting ring by welding, an intermediate column is fixed to one end of the connecting rod by welding, one side of the intermediate column is open, and a centering block is fixed to the inner wall of the open side by welding, a Roots pump housing is arranged on one side of the centering block, a pump shaft is rotatably arranged inside the Roots pump housing, pump blades are fixed to the outside of the pump shaft by welding, one end of the pump shaft extends out of the side wall of the Roots pump housing, and one end of the pump shaft is a matching structure with the centering block.

[0008] According to the above technical solution, a friction coupling plate is installed at one end of the centering block, and the friction coupling plate and the pump shaft are in abutment contact with each other.

[0009] According to the above technical solution, the upper and lower sides of the Roots pump housing are fixed with circulation pipes by welding, the circulation pipes are fixed to the outer wall of the building body by welding, and several Roots pump housings located on the same side of the building body are interconnected through the circulation pipes, and a hydraulic motor is connected between the two ends of the Roots pump housing, and the output end of the hydraulic motor is connected to a torque generator through torque, and the output end of the torque generator is electrically connected to the external power grid.

[0010] According to the above technical solution, a two-position, two-way reversing valve is arranged between the two ends of the Roots pump housing and the hydraulic motor, the two-position, two-way reversing valve is installed on the circulation pipeline, the output port of the Roots pump housing is connected with a pressure sensor, and the pressure sensor is electrically connected to the two-position, two-way reversing valve through an external control system.

[0011] According to the above technical solution, a groove is opened on one side of the middle column, and a pin shaft is fixed in the groove by welding, and a moving plate is rotatably sleeved on the outside of the pin shaft, and a triangular gear ring is evenly installed on the outer wall of one end of the pump shaft, and the triangular gear ring is in contact with the moving plate, and an elastic tensioning piece is clamped between the moving plate and the inner wall of one side of the groove, and a slider is hinged at one end of the moving plate, and a lateral push button is installed at one end of the slider.

[0012] According to the above technical solution, the working method of the system includes:

[0013] S1. When the outside wind blows through the vent, the wind force drives the wind blades to rotate, and transmits the rotational torque to the pump shaft, driving it to rotate;

[0014] S2. The rotation of the pump blades causes the liquid to be pumped to the input end of the hydraulic motor, and then the output end of the hydraulic motor operates, transmitting the torque to the torque generator for power generation, and then storing the electrical energy;

[0015] S3. When the wind direction changes, the liquid flow direction is changed, and the guide of the two-position two-way reversing valve is switched, so that the inlet and outlet connected to the hydraulic motor are swapped, and power generation continues;

[0016] S4. When disassembling the Roots pump housing, press the side push button inward, move the moving plate away, and take out the pump shaft.

[0017] Multiple blades are set on the vents. When wind blows through the building from outside to inside or from inside to outside, this part of the wind force will be converted to recycle wind energy, thereby improving the energy utilization efficiency of the power supply building, which is beneficial to energy conservation and environmental protection.

[0018] When working, wind energy will first drive the wind blades to rotate, thereby converting the wind force into the rotational force of the mounting ring. The extension plate is used to maintain the position of the mounting ring so that it can rotate smoothly without falling down. The contact side of the extension plate and the mounting ring is preferably provided with a flexibly rotating roller or ball, which can reduce the friction between the two and make rotation more convenient.

[0019] When the mounting ring is rotated, the rotational torque is transmitted to the pump shaft, driving the pump shaft to rotate, and the pump blades will rotate together. At this time, the liquid in the Roots pump casing will be pumped from top to bottom or from bottom to top, thereby converting the rotational force into the hydraulic pressure of the liquid, which is convenient for centralized collection of kinetic energy. There is no need to set up multiple generators, and the kinetic energy can be transmitted over long distances.

[0020] When in use, the liquid pressure is transmitted through the circulation pipeline and transmitted to the hydraulic motor. When the hydraulic motor is in operation, it converts the pressure energy of the liquid into rotational kinetic energy and transmits the kinetic energy to the torque generator, so as to transmit the rotational torque and convert it into electrical energy.

[0021] This design can utilize the airflow difference collected by the wind recovery device, convert it into electrical energy through the Roots pump housing and hydraulic motor, and finally output it to the external power grid to achieve energy recovery and utilization, thereby reducing dependence on traditional energy and reducing energy consumption costs. At the same time, this design can also improve the stability and quietness of the building and reduce the impact of noise and vibration on the building and residents.

[0022] Since the wind directions in the four directions of the building body are inconsistent, some directions will blow outwards, and some directions will blow inwards. The positive wind direction will cause positive pressure, and the reverse direction will cause pressure reduction. The pressure is monitored by the pressure sensor, so that the two-position two-way reversing valve is correctly connected, so that the inlet port of the hydraulic motor has positive pressure and the outlet port has negative pressure, which is convenient for gathering the kinetic energy of the liquid; the working principle of this design is that when the Roots pump housing is started, the hydraulic oil enters one end of the hydraulic motor through the two-position two-way reversing valve, so that the Roots pump rotates and sucks in the medium, and then compresses the medium and discharges it from the other end. The pressure sensor can monitor the pressure of the medium in real time, and control the hydraulic motor and the two-position two-way reversing valve through the external control system to ensure the normal operation of the equipment.

[0023] During installation, squeeze the side push button inwards and drive the slider to slide, so that one end of the moving plate is tilted to facilitate the insertion of the pump shaft. After insertion, the pump shaft will be restricted in the groove due to the blocking effect of the triangular gear ring, preventing the pump shaft from falling off while not hindering the rotation of the pump shaft. When disassembling, compress the elastic tensioning sheet again to make the two separate.

[0024] Compared with the prior art, the beneficial effect achieved by the present invention is: the present invention arranges multiple blades on the vent, and when the wind blows through the building from the outside to the inside or from the inside to the outside, this part of the wind power will be converted to recycle wind energy, thereby improving the energy utilization efficiency of the power supply building, which is beneficial to energy conservation and environmental protection.

DETAILED DESCRIPTION

[0035] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0036] Embodiment 1

[0037] See also Figure 1-Figure 6 The present invention provides a technical solution: a renewable energy system for power supply buildings, comprising a building body 1, a plurality of vents 2 are evenly opened on the side wall of the building body 1, a wind recovery device 3 is arranged inside the vents 2, and the wind recovery device 3 can utilize the difference in airflow inside and outside the building, when the external fresh air is introduced into the room, or the indoor exhaust gas is discharged, the kinetic energy of the airflow is utilized when the indoor air is circulated, and converted into electrical energy;

[0038] Multiple blades are set on the vents. When wind blows through the building from outside to inside or from inside to outside, this part of the wind force will be converted to recycle wind energy, thereby improving the energy utilization efficiency of the power supply building, which is beneficial to energy conservation and environmental protection.

[0039] The wind recovery device 3 includes a mounting ring 31. The inner walls of the upper and lower sides of the vent 2 are correspondingly fixed with longitudinal plates 36 by welding. One end of the longitudinal plate 36 is connected with an extension plate 361 by welding. The mounting ring 31 is slidably clamped between the two extension plates 361, and the mounting ring 31 is rotatable. The outer wall of the mounting ring 31 is evenly distributed with wind blades 32 in a circumferential manner. When working, the wind energy will first drive the wind blades 32 to rotate, thereby converting the wind force into the rotational force of the mounting ring 31. The extension plate 361 is used to maintain the position of the mounting ring 31 so that it can rotate smoothly without falling downward. The contact side of the extension plate 361 and the mounting ring 31 is preferably provided with a flexibly rotating roller or ball, which can reduce the friction between the two and make the rotation more convenient.

[0040] The inner wall of the mounting ring 31 is uniformly fixed with a connecting rod 33 by welding, one end of the connecting rod 33 is fixed with an intermediate column 331 by welding, one side of the intermediate column 331 is open, and the inner wall of the open side is fixed with a centering block 332 by welding, one side of the centering block 332 is provided with a Roots pump housing 34, the inner part of the Roots pump housing 34 is rotatably provided with a pump shaft 342, the outer part of the pump shaft 342 is fixed with a pump blade 341 by welding, and one end of the pump shaft 342 extends out of the Roots pump housing 34 The side wall of the pump shaft 342 is provided with a matching structure at one end of the pump shaft 342 and the centering block 332. When the mounting ring 31 is rotated, the rotational torque is transmitted to the pump shaft 342, and the pump shaft 342 is driven to rotate, and the pump blades 341 are rotated together. At this time, the liquid in the Roots pump housing 34 is pumped from top to bottom or from bottom to top, thereby converting the rotational force into the hydraulic pressure of the liquid, which is convenient for centralized collection of kinetic energy, without the need to set up multiple generators, and the kinetic energy can be transmitted over a long distance;

[0041] A friction coupling plate 334 is installed at one end of the centering block 332. The friction coupling plate 334 and the pump shaft 342 are in contact with each other. When the intermediate column 331 rotates, the centering block 332 is driven to rotate synchronously. The friction force of the friction coupling plate 334 is used to drive the pump shaft 342 to rotate, so as to facilitate the transmission of the rotational torque.

[0042] The upper and lower sides of the Roots pump housing 34 are fixed with flow pipes 35 by welding, and the flow pipes 35 are fixed to the outer wall of the building body 1 by welding. A plurality of Roots pump housings 34 located on the same side of the building body 1 are interconnected through the flow pipes 35. A hydraulic motor 37 is connected between the two ends of the Roots pump housing 34. The output end of the hydraulic motor 37 is connected to a torque generator 371 through torque. The output end of the torque generator 371 is electrically connected to an external power grid. When in use, the liquid pressure is transmitted through the flow pipes 35 and transmitted to the hydraulic motor 37. When the hydraulic motor 37 is in operation, the pressure energy of the liquid is converted into kinetic energy of rotation, and the kinetic energy is transmitted to the torque generator 371, so as to facilitate the transmission of the rotational torque and convert it into electrical energy.

[0043] Such a design can utilize the airflow difference collected by the wind recovery device 3, convert it into electrical energy through the Roots pump housing 34 and the hydraulic motor 37, and finally output it to the external power grid to achieve energy recovery and utilization, thereby reducing dependence on traditional energy and reducing energy consumption costs. At the same time, such a design can also improve the stability and quietness of the building and reduce the impact of noise and vibration on the building and residents.

[0044] A two-position two-way reversing valve 39 is provided between the two ends of the Roots pump housing 34 and the hydraulic motor 37. The two-position two-way reversing valve 39 is installed on the circulation pipe 35. The output port of the Roots pump housing 34 is connected through a pressure sensor 38. The pressure sensor 38 is electrically connected to the two-position two-way reversing valve 39 through an external control system. Since the wind directions in the four directions of the building body 1 are inconsistent, some directions will blow outwards and some directions will blow inwards. The positive wind direction will cause positive pressure and the reverse direction will cause pressure reduction. The pressure is monitored by the pressure sensor 38, so that the two-position two-way reversing valve 39 is correctly connected, so that the inlet port of the hydraulic motor 37 just has positive pressure and the outlet port has negative pressure, which is convenient for gathering the kinetic energy of the liquid. The working principle of this design is that when the Roots pump housing 34 is started, the hydraulic oil enters one end of the hydraulic motor 37 through the two-position two-way reversing valve 39, so that the Roots pump rotates and sucks in the medium, and then compresses the medium and discharges it from the other end. The pressure sensor 38 can monitor the pressure of the medium in real time, and control the hydraulic motor 37 and the two-position two-way reversing valve 39 through an external control system to ensure the normal operation of the equipment.

[0045] A groove is provided on one side of the middle column 331, and a pin shaft 333 is fixed in the groove by welding. A moving plate 335 is rotatably sleeved on the outer side of the pin shaft 333. A triangular gear ring 336 is evenly installed on the outer wall of one end of the pump shaft 342. The triangular gear ring 336 is in contact with the moving plate 335. The moving plate 335 and the inner wall of one side of the groove are clamped with an elastic expansion and contraction piece 337. A slider 339 is hinged on one end of the moving plate 335. A lateral push button 338 is installed on one end of the slider 339. During installation, the lateral push button 338 is pressed inwardly, and the slider 339 is driven to slide, so that one end of the moving plate 335 is tilted, which is convenient for the insertion of the pump shaft 342. After insertion, the pump shaft 342 will be restricted in the groove due to the blocking effect of the triangular gear ring 336, preventing the pump shaft 342 from falling off while not hindering the rotation of the pump shaft 342. When disassembling, the elastic expansion and contraction piece 337 is compressed again, so that the two can be separated.

[0046] The system's working methods include:

[0047] S1. When the outside wind blows through the vent 2, the wind force drives the wind blade 32 to rotate, and transmits the rotational torque to the pump shaft 342 to drive it to rotate; through this use method, the wind force can be converted into rotational force. Because the wind force is difficult to capture, the conversion into rotational force can facilitate the centralized conversion of discrete wind force, so as to facilitate the centralized recovery of wind energy;

[0048] S2. The rotation of the pump blade 341 causes the liquid to be pumped to the input end of the hydraulic motor 37, and then the output end of the hydraulic motor 37 operates, transmitting the torque to the torque generator 371 for power generation, and then storing the electrical energy; this design can convert hydraulic energy into electrical energy for storage, thereby realizing energy conversion and storage, which is conducive to improving energy utilization efficiency and reducing energy waste. In addition, the hydraulic motor and torque generator have a simple structure, high reliability, high efficiency and stability, and can meet the energy needs of industrial production;

[0049] S3. When the wind direction changes, the liquid flow direction is changed, and the guide of the two-position two-way reversing valve 39 is switched, so that the inlet and outlet connected to the hydraulic motor 37 are swapped, and power generation continues; the advantage of this design is that power generation can continue when the wind direction changes, avoiding energy supply interruption caused by unstable wind. At the same time, the liquid flow direction conversion can also realize energy storage and conversion, improve energy utilization efficiency and reduce energy waste. In addition, switching the guide of the two-position two-way reversing valve can realize automatic control, improve production efficiency and stability.

[0050] S4. When disassembling the Roots pump housing 34, the side push button 338 is pushed inward, the moving plate 335 is moved away, and the pump shaft 342 is taken out. The advantage of this design is that it is convenient to repair and replace the Roots pump housing, and improves the reliability and maintainability of the equipment. At the same time, the design of the side push button can also avoid misoperation and ensure safety.

[0051] Embodiment 2

[0052] Based on the first embodiment, Figure 7-Figure 8 As shown, an aperture adjustment device 4 is provided at the outer opening of each vent 2, which moves in a plane perpendicular to the axis of the vent 2. Specifically, the aperture adjustment device 4 includes two transparent moving blocks 40 that move in a vertical plane, and the two transparent moving blocks 40 move up and down vertically or move left and right horizontally.

[0053] A rectangular frame 41 is disposed at the outer opening of each vent 2 , and the two transparent moving blocks 40 are slidably disposed on the rectangular frame 41 .

[0054] When it is rainy and strong, the two transparent moving blocks 40 move toward each other to close the vent 2 to prevent rainwater from entering the building body 1.

[0055] When it is extremely windy, the two transparent moving blocks 40 move toward each other to reduce the aperture of the vent 2 to prevent the wind power recovery device 3 from overloading due to extremely strong wind.

[0056] Of course, when the wind recovery is not needed, the transparent moving block 40 can play a role similar to a window.

[0057] The sliding rods 42 are respectively provided at the center of the two opposite sides of the rectangular frame 41 and are slidably connected to the rectangular frame 41. The sliding connection adopts a structure similar to a guide rail pair, and the two sliding rods 42 move in the same straight line. The sliding rods 42 slide relative to the rectangular frame 41 to ensure the movement stability of the corresponding transparent moving block 40.

[0058] An extension rod 43 is provided at the end of one of the two sliding rods 42 near the other sliding rod 42, and a blind hole 44 is provided at one end of the other sliding rod 42 near the extension rod 43. The depth of the blind hole 44 is greater than the length of the extension rod 43, and the gap between the two is matched. The matching of the extension rod 43 and the blind hole 44 can make the sliding of the two sliding rods 42 more stable. Of course, when the two transparent moving blocks 40 close the vent 2, the two sliding rods 42 at this time are pressed against each other at one end to play the role of limit limit, so as to prevent the two transparent moving blocks 40 from colliding with each other and causing cracks and the like.

[0059] For ease of understanding, in this embodiment, one end of the sliding rod 42 close to the center of the rectangular frame 41 is defined as the inner end, and the other end is defined as the outer end.

[0060] A connecting rod 45 vertically connected to the sliding rod 42 is respectively provided at the outer end of each sliding rod 42 , and the connecting rod 45 is fixedly connected to one side of the transparent moving block 40 .

[0061] Secondly, in the moving direction of the transparent moving block 40, rectangular side holes 46 are respectively provided on the opposite side edges of the rectangular frame 41, and a transparent moving block 40 is inserted into one of the rectangular side holes 46. Rolling members 47 that are movably in contact with the opposite sides of the transparent moving block 40 are respectively provided in the rectangular side holes 46. The two rolling members 47 and the connecting rod 45 form an isosceles triangle distribution.

[0062] There are rolling elements 47 on both surfaces of the transparent moving block 40 in the thickness direction, that is, the rolling elements 47 are arranged in pairs of two in the thickness direction of the transparent moving block 40 , and there are two pairs.

[0063] The rolling element 47 is, for example, a guide plate with an array of distributed balls.

[0064] Each sliding rod 42 is connected to a driver 48, which is, for example, any one of an air cylinder, an oil cylinder and a linear motor. The driver 48 is fixed to the outer facade of the building body 1. It is preferably a linear motor.

[0065] Taking two sliding rods 42 as an example, the two drivers 48 can be driven synchronously or asynchronously, and the moving stroke of the transparent moving block 40 can be determined according to the actual wind force.

[0066] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0067] Finally, it should be noted that the above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
