[0033] To further illustrate each embodiment, the present invention provides drawings, which are part of the disclosure of the present invention and are mainly used to illustrate the embodiments and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these contents, ordinary technicians in the field should be able to understand other possible implementations and advantages of the present invention. The components in the figures are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0034] According to an embodiment of the present invention, an energy collection system for a green building is provided.

[0035] The present invention is further described with reference to the accompanying drawings and specific embodiments. Figure 1-Figure 12 As shown, an energy collection system for a green building according to an embodiment of the present invention comprises: a rainwater collection box 1, a solar panel 5, a turbine mechanism 7, a wind wheel mechanism 8, and a generator 9. An opening 1a is provided on the top of the rainwater collection box 1, a drainage pipe 2 is provided at the bottom of the rainwater collection box 1, a float switch 3 is provided at the water inlet of the drainage pipe 2, and a fixing seat 4 is provided on the outer pipe wall of the drainage pipe 2; the solar panel 5 is located above the opening 1a and is connected to the rainwater collection box 1, the solar panel 5 is inclined, and water guide plates 6 are provided on the left and right sides of the solar panel 5, and the water guide plates 6 extend downward into the rainwater collection box 1; the turbine mechanism 7 is arranged in the drainage pipe 2; the wind wheel mechanism 8 is arranged on the fixing seat 4; a motor shaft 9a is provided on the generator 9, the turbine mechanism 7 and the wind wheel mechanism 8 are linked to the movement of the motor shaft 9a, and the generator 9 and the solar panel 5 are electrically connected to a battery.

[0036] The energy collection system can be installed outside a window, and the solar panel 5 can convert light energy into electrical energy and store it in a battery under the irradiation of the sun.

[0037] When it rains, the rainwater falling on the solar panel 5 can be discharged into the rainwater collection box 1 under the action of the water guide plate 6. During the initial period of time, the float switch 3 will block the water inlet of the drainage pipe 2 until the rainwater in the rainwater collection box 1 reaches a certain amount, and the buoyancy of the rainwater on the float switch 3 is greater than the weight of the float switch 3. At this time, the float switch 3 moves upward to open the water inlet of the drainage pipe 2, and the rainwater will be discharged downward along the drainage pipe 2. When passing through the turbine mechanism 7, it drives the turbine to rotate and transmits power to the motor shaft 9a, driving the generator 9 to generate electricity, and then storing the electricity in the battery.

[0038] When there is wind, the wind drives the wind wheel of the wind wheel mechanism 8 to rotate, and transmits power to the motor shaft 9a, driving the generator 9 to generate electricity, and then storing the electricity in the battery.

[0039] With the aid of the above technical scheme, the present invention can collect rainwater through the combination of solar panels 5 and rainwater collection box 1, and can reasonably generate electricity with the help of rainwater through the combination of drainage pipe 2, turbine mechanism 7 and generator 9, and can also generate electricity by wind power through the combination of wind wheel mechanism 8 and generator 9. It can be seen that the present invention can maximize the use of light energy, rainwater and wind power to realize the collection of natural energy, provide the required electricity for the building, and conform to the concept of environmental protection and green.

[0040] In some embodiments, Figure 4 , Figure 6 , Figure 7 , Figure 8 , Fig. 9 , Fig.11 As shown, the turbine mechanism 7 includes: a fixed bracket 71, a turbine impeller 72, a transmission assembly 73, and a first spring 74. The fixed bracket 71 is connected to the inner wall of the drainage pipe 2. The turbine impeller 72 is provided with a pivot shaft 72a, and the pivot shaft 72a is movably arranged on the fixed bracket 71 up and down. The lower end of the pivot shaft 72a located at the fixed bracket 71 is provided with a connecting seat 72b, and the connecting seat 72b is provided with a first spline groove 72c. The input end of the transmission assembly 73 is provided with a first spline 73a, and the output end of the transmission assembly 73 extends out of the drainage pipe 2 and moves in conjunction with the motor shaft 9a. One end of the first spring 74 stops on the turbine impeller 72 and the other end stops on the fixed bracket 71. When the turbine impeller 72 is impacted by rainwater, the first spring 74 can be compressed to make the first spline groove 72c and the first spline 73a cooperate.

[0041] The working principle of the turbine mechanism 7 is as follows: the discharged rainwater will drive the turbine impeller 72 to rotate, and at the same time, the turbine impeller 72 moves downward under the action of the rainwater, compressing the first spring 74. At this time, the first spline groove 72c and the first spline 73a cooperate, so that the transmission assembly 73 can transmit the power of the turbine impeller 72 to the motor shaft 9a, so that the generator 9 generates electricity. When the rainwater disappears, the first spring 74 can be elastically reset, so that the turbine impeller 72 moves upward. At this time, the first spline groove 72c and the first spline 73a are disengaged to reduce the load on the motor shaft 9a. In this way, the turbine mechanism 7 can automatically be linked with the motor shaft 9a, that is, when rainwater passes through the turbine impeller 72, the turbine mechanism 7 can work and drive the generator 9 to generate electricity. When there is no rainwater passing through the turbine impeller 72, the turbine mechanism 7 does not link with the generator 9, which can ensure that the operation of the generator 9 is not affected by the turbine mechanism 7.

[0042] In some embodiments, Figure 4 , Figure 7 As shown, the fixed bracket 71 is provided with a second bracket 71a extending downward, and the transmission assembly 73 includes: a first pulley 731, a second pulley 732, and a cross belt 733. The first pulley 731 is an output end and is rotatably provided on the second bracket 71a. A support seat 10 is provided on the fixed seat 4, and the second pulley 732 is an output end and is rotatably connected to the support seat 10. One end of the cross belt 733 is sleeved on the first pulley 731 and the other end is sleeved on the second pulley 732. An avoidance hole 2a is provided on the pipe wall of the drainage pipe 2, and the cross belt 733 is inserted into the avoidance hole 2a. When the first spline groove 72c and the first spline 73a cooperate, the turbine impeller 72 drives the first pulley 731 to rotate, and then transmits it to the second pulley 732 through the cross belt 733. Driven by the second pulley 732, the motor shaft 9a is finally rotated. The use of this cross-belt transmission assembly can convert the power of the turbine impeller 72 rotating around the vertical axis into the power of the second pulley 732 rotating around the horizontal axis.

[0043] In some embodiments, Figure 4 , Figures 6 to 9 As shown, a linkage mechanism 11 is provided between the motor shaft 9a and the turbine impeller 72, and the linkage mechanism 11 includes: a lever 111, a stop rod 112, and a push block 113. The lever 111 is rotatably connected to the fixed seat 4 and one end is inserted into the avoidance hole 2a. The stop rod 112 is provided on one end of the lever 111 located at the drainage pipe 2, and the stop rod 112 stops at the bottom of the connecting seat 72b. The push block 113 is provided on the other end of the lever 111. A groove 113a is provided on the push block 113. The motor shaft 9a is located in the groove 113a. The end of the push block 113 close to the second pulley 732 is provided with a thrust surface 113b arranged obliquely upward.

[0044] The second pulley 732 is movably arranged on the support seat 10 along the front-to-back direction, the second pulley 732 is sleeved on the motor shaft 9a and is clearance-matched with the motor shaft 9a, a second spline groove 732a is provided on the second pulley 732, and a second spline 9b located on the front side of the second pulley 732 is provided on the motor shaft 9a. The second pulley 732 can move forward under the action of the thrust surface 113b to make the second spline groove 732a and the second spline 9b match, a shaft mounting seat 12 is provided on the fixed seat 4, and the shaft mounting seat 12 is located on the front side of the second spline 9b, a second spring 13 is provided on the shaft mounting seat 12, and a ball seat 14 is provided at the end of the second spring 13, and a ball 15 is provided in the ball seat 14, and the ball 15 stops on the second pulley 732.

[0045] The working principle of the linkage mechanism 11 is as follows: when the turbine impeller 72 moves downward, it will drive the stop rod 112 to move downward, and then drive the other end of the lever 111 to swing upward. At this time, the push block 113 pushes the second pulley 732 forward on the support seat 10 through the action of the thrust surface 113b on it. At this time, the second spline groove 732a and the second spline 9b cooperate to transmit the power of the second pulley 732 to the motor shaft 9a, so that the generator 9 generates electricity. During the forward movement of the second pulley 732, it will push the ball 15 and the ball seat 14, compressing the second spring 13. When the rainwater is drained, the force on the turbine impeller 72 disappears. At this time, the second spring 13 can restore its length, and the power of the second pulley 732 and the motor shaft 9a is disconnected through the ball seat 14 and the ball 15. The use of the structure of the ball seat 14 and the ball 15 will not affect the normal rotation of the second pulley 732.

[0046] In some embodiments, Fig.13 , Fig.14 As shown, a rainwater collecting plate 20 is provided in the drainage pipe 2. The middle part of the rainwater collecting plate 20 is in the shape of a cone that bulges upwards. The rainwater collecting plate 20 is provided with an annular recess 20a arranged around the center thereof. The recess 20a is provided with a plurality of water outlet holes 20b. The plurality of water outlet holes 20b are arranged at equal intervals along the circumferential direction. When rainwater flows down from the water inlet of the drainage pipe 2, it will gather in the recess 20a when passing through the upwardly bulging cone in the middle part of the rainwater collecting plate 20, and then pour down through the water outlet holes 20b and fall onto the turbine impeller 72. The arrangement can ensure that the rainwater concentrates on the blades of the turbine impeller 72, making it easier for the turbine impeller 72 to rotate. In some embodiments, as Figure 6 As shown, a water blocking plate 16 is provided on the inner wall of the drainage pipe 2 above the avoidance hole 2a, and the water blocking plate 16 is located below the turbine impeller 72. The water blocking plate 16 can prevent rainwater from splashing out from the side of the drainage pipe 2.

[0047] In some embodiments, Figure 7 , Figure 8 , Fig. 9 , Fig.11 As shown, the wind wheel mechanism 8 includes: a wind impeller 81, an active conical friction wheel 82, a driven conical friction wheel 83, and a third spring 84. The fixed seat 4 is provided with an impeller mounting seat 41, and the wind impeller 81 is provided with an impeller shaft 81a. The impeller shaft 81a is movably arranged on the impeller mounting seat 41 along the front-rear direction. The active conical friction wheel 82 is arranged on the impeller shaft 81a. One end of the third spring 84 is stopped on the impeller mounting seat 41 and the other end is stopped on the active conical friction wheel 82. The driven conical friction wheel 83 is arranged on the motor shaft 9a. Under the action of wind, the wind impeller 81 drives the impeller shaft 81a to move backward, so that the active conical friction wheel 82 compresses the third spring 84 and contacts and cooperates with the driven conical friction wheel 83.

[0048] The working principle of the wind wheel mechanism 8 is as follows: when there is strong wind, the wind force acts on the wind impeller 81, which can drive the wind impeller 81 to rotate, and can also drive the wind impeller 81 to move backward on the impeller mounting seat 41 along with the impeller shaft 81a. During the backward movement, the third spring 84 is compressed, and the active conical friction wheel 82 and the driven conical friction wheel 83 are in friction contact, so that the driven conical friction wheel 83 can rotate, and then the driven conical friction wheel 83 drives the motor shaft 9a to rotate, so that the generator 9 generates electricity and stores electrical energy in the battery. According to the foregoing, since the power between the turbine mechanism 7 and the motor shaft 9a is disconnected (there is wind but no rain), the power of the wind impeller 81 can be fully transmitted to the motor shaft 9a at this time, so that the generator 9 can generate electricity with high efficiency. When the wind stops, the third spring 84 can restore its length, thereby disconnecting the power between the wind impeller 81 and the motor shaft 9a, and the wind impeller 81 and the motor shaft 9a remain disconnected under normal circumstances. This ensures that in the case of rain but no wind, the turbine impeller 72 can completely transfer power to the motor shaft 9a, so that the generator 9 can generate electricity efficiently.

[0049] In some embodiments, Figure 7 , Figure 8 , Fig. 9 , Fig.11 As shown, the diameter of the active conical friction wheel 82 is larger than the diameter of the driven conical friction wheel 83. In this way, the active conical friction wheel 82 and the driven conical friction wheel 83 form a speed increasing mechanism, which can make the fan wheel 81 drive the motor shaft 9a to rotate quickly, thereby improving the power generation efficiency of the generator 9.

[0050] In some embodiments, Figure 3 , Figure 5As shown, the float switch 3 includes: a first cavity float 31, a second cavity float 32, and a connecting cavity tube 33. The bottom of the first cavity float 31 is conical and fits on the water inlet of the drainage pipe 2. The top of the first cavity float 31 is provided with an arc surface 31a. The second cavity float 32 is located above the first cavity float 31, and the orthographic projection of the second cavity float 32 is larger than the orthographic projection of the first cavity float 31. One end of the connecting cavity tube 33 is connected to the first cavity float 31 and the other end is connected to the second cavity float 32. A float mounting seat 17 is provided on the pipe wall of the rainwater collection box 1, and the connecting cavity tube 33 is movably arranged on the float mounting seat 17 up and down.

[0051] The working principle of the float switch 3 is as follows: the structural design of the first cavity float 31, the second cavity float 32, and the connecting cavity tube 33 makes the cavity volume of the float switch 3 relatively large, so that the rainwater in the rainwater collection box 1 can be opened after a certain volume is collected. The bottom of the first cavity float 31 is conical, which can better fit on the water inlet of the drainage pipe 2, ensure the sealing, and avoid water leakage at the water inlet. The top of the first cavity float 31 is provided with an arc surface 31a, which is conducive to the rainwater flowing down along the arc surface 31a. The float mounting seat 17 provides support and guidance to ensure that the float switch 3 can move stably in the up and down directions.

[0052] In some embodiments, Figure 1 , Figure 3 , Fig.12 As shown, at least two mounting mechanisms 18 are provided on the rear side of the rainwater collection box 1, and the mounting mechanism 18 includes: a clamping seat 181, a clamping bolt 182, and a clamping block 183. The clamping seat 181 is provided on the rear side wall of the rainwater collection box 1, and a bayonet 181a is provided on the clamping seat 181. The clamping bolt 182 is threadedly connected to the clamping seat 181, and the bottom of the clamping bolt 182 passes through the clamping seat 181 and extends into the bayonet 181a. The clamping block 183 is located in the bayonet 181a and is connected to the clamping bolt 182. An adjusting knob 182a is provided on the top of the clamping bolt 182.

[0053] The working principle of the mounting mechanism 18 is as follows: the rainwater collection box 1 can be mounted on the boss outside the window, that is, the bayonet 181a of the bayonet seat 181 is clamped on the boss, and the clamping bolt 182 is moved downward by turning the adjusting knob 182a, so that the clamping block 183 is pressed on the top of the boss, and finally the rainwater collection box 1 is tightly fixed on the boss. The installation reliability of the rainwater collection box 1 can be improved by providing two mounting mechanisms 18.

[0054] In some embodiments, Figure 1 , Fig.12As shown, a water baffle 19 is provided above the fixing base 4, and the generator 9 and at least a part of the wind rotor mechanism 8 are located below the water baffle 19. The water baffle 19 plays a role in shielding rain and sunlight, and can prevent the generator 9 and at least a part of the wind rotor mechanism 8 from being exposed to sunlight and rain for a long time, which is beneficial to prolonging the service life of the components.

[0055] In order to facilitate understanding of the above technical solutions of the present invention, the working principle or operation mode of the present invention in the actual process is described in detail below.

[0056] The following describes the specific use of energy harvesting systems for green buildings:

[0057] like Figures 1 to 12 As shown, first, install the two mounting seats 181 of the mounting mechanisms 18 on the rear side of the rainwater collection box 1 on the boss outside the window, turn the adjusting knob 182a to move the clamping bolt 182 downward, and press the clamping block 183 on the top of the boss to fix the rainwater collection box 1 as a whole outside the window.

[0058] In the collection system, the solar panel 5 can generate electricity continuously for a long time under the action of light, and store the electricity in the battery to power indoor equipment.

[0059] When it rains, part of the rainwater enters directly from the opening on the top of the rainwater collection box 1, and the other part of the rainwater can hit the solar panel 5. The solar panel 5 has a large bearing surface, which can improve the rainwater collection capacity. At the same time, the rainwater can be gathered to the bottom along the water guide plates 6 on the left and right sides, and enter the rainwater collection box 1 from the area between the two water guide plates 6. When a certain amount of rainwater is collected, the buoyancy of the float switch 3 is greater than its own gravity. The float switch 3 moves upward to open the water inlet of the drainage pipe 2, and the collected rainwater pours down from the drainage pipe 2. During this period, the rainwater will act on the turbine impeller 72, which can drive the turbine impeller 72 to rotate and drive the turbine impeller 72 to move downward. Then the first spline groove 72c on the connecting seat 72b and the first spline 73a on the first pulley 731 cooperate to drive the first pulley 731 to rotate, and the second pulley 732 rotates under the action of the cross belt 733. As the connecting seat 72b moves downward with the turbine impeller 72, it pushes the stop rod 112 to move downward, causing the right end of the lever 111 to swing upward. At this time, the push block 113 drives the second pulley 732 to move forward through the thrust surface 113b thereon, causing the second spline groove 732a and the second spline 9b to cooperate, thereby transmitting the rotation of the second pulley 732 to the motor shaft 9a, allowing the generator 9 to generate electricity.

[0060] When the rainwater is drained, the first spring 74 will elastically reset, causing the first spline groove 72c and the first spline 73a to disengage. At the same time, the second spring 13 will elastically reset, allowing the ball 15 to push the second pulley 732 to move backward, causing the second spline groove 732a and the second spline 9b to disengage, thereby releasing the power transmission between the turbine impeller 72 and the motor shaft 9a.

[0061] When there is wind, the wind acts on the impeller 81, which can drive the impeller 81 to rotate and move backward on the impeller mounting seat 41 along with the impeller shaft 81a, so that the active conical friction wheel 82 and the driven conical friction wheel 83 are in friction contact, and the driven conical friction wheel 83 drives the motor shaft 9a to rotate, so that the generator 9 generates electricity and stores electrical energy in the battery.

[0062] When the wind force becomes smaller or disappears completely, the third spring 84 elastically returns to its original position, pushing the active conical friction wheel 82 and the impeller shaft 81a to move forward, thereby releasing the power transmission between the impeller 81 and the motor shaft 9a.

[0063] As can be seen from the above, the energy collection system of the green building of the present invention can timely utilize sunlight, rainwater and wind power to generate electricity, realize the collection of natural energy, provide the required electricity for the building, and comply with the green concept of environmental protection.

[0064] In the present invention, unless otherwise clearly stipulated and limited, the terms such as "installation", "setting", "connection", "fixation" and "screw-on" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral one; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be the internal connection of two elements or the interaction relationship between two elements. Unless otherwise clearly defined, ordinary technicians in this field can understand the specific meanings of the above terms in the present invention according to the specific circumstances.

[0065] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
