Description

Technical Field

[0001] The present application relates to the field of photovoltaic power generation technology, and in particular to a photovoltaic power generation rack and a unit with a quasi-stepless regulation function, that is, a photovoltaic power generation rack with a quasi-stepless regulation function and a photovoltaic power generation unit with a quasi-stepless regulation function. Background Art

[0002] Photovoltaic power generation is a technology that uses the photovoltaic effect of the semiconductor interface to directly convert light energy into electrical energy. Specifically, the main principle of photovoltaic power generation is that when photons irradiate the semiconductor, its energy can be completely absorbed by an electron in the semiconductor. The energy absorbed by the electron is large enough to overcome the Coulomb force inside the semiconductor atom to do work, escape from the semiconductor surface and become a photoelectron. Silicon atoms have 4 outer electrons. If atoms with 5 outer electrons, such as phosphorus atoms, are doped into pure silicon, it becomes an N-type semiconductor; if atoms with 3 outer electrons, such as boron atoms, are doped into pure silicon, a P-type semiconductor is formed. When the P-type and N-type are combined together, a potential difference will be formed at the contact surface, forming a solar cell. When sunlight irradiates the P-N junction, the current will flow from the P-type side to the N-type side, forming a current.

[0003] The patent document with the authorization announcement number CN209345076U discloses a retractable photovoltaic power generation device, which drives the photovoltaic rack to rise and fall to protect the photovoltaic rack through the cooperation of the threaded transmission mechanism and the connecting rod transmission mechanism. However, the retractable photovoltaic power generation device has the following disadvantages:

[0004] When the retractable photovoltaic power generation device is performing photovoltaic power generation, the efficiency of photovoltaic power generation varies due to the different positions of the sun. The retractable photovoltaic power generation device is not convenient for the photovoltaic power generation panel to track the sun, thus reducing the efficiency of photovoltaic power generation.

[0005] When the retractable photovoltaic power generation device generates electricity, the angle needs to be adjusted so that the photovoltaic power generation panel is aligned with the sun, which is labor-intensive and difficult to accurately align the power generation panel with the sun, thereby reducing the flexibility of the photovoltaic power generation panel in rotation.

[0051] The present application discloses a photovoltaic power generation rack and unit with a quasi-stepless adjustment function, which includes some or all of the technical features of the following embodiments; that is, the photovoltaic power generation rack and unit with a quasi-stepless adjustment function include some or all of the following structures. In one embodiment of the present application, a photovoltaic power generation rack with a quasi-stepless adjustment function includes a tracking component, a mounting seat and an adjustment component; the tracking component and the adjustment component are respectively arranged on the mounting seat, and the adjustment component is used to connect the photovoltaic power generation panel; the tracking component includes a photoresistor, a servo motor and a transmission rod, the photoresistor is conductively connected to the servo motor, the output end of the servo motor is transmission-connected to the transmission rod, and the transmission rod is connected to the adjustment component; the photoresistor drives the position of the adjustment component through the servo motor and the transmission rod to adjust the position of the photovoltaic power generation panel. The above-mentioned photovoltaic power generation rack with quasi-stepless adjustment function cooperates with the adjustment component through the tracking component. When the sunlight is unevenly irradiated on the surface of the photovoltaic panel, the photoresistor drives the adjustment component to adjust the position of the photovoltaic panel with the light, so that the photovoltaic panel has a quasi-stepless adjustment function and is always accurately aligned with the sun, so that the photovoltaic panel tracks the sun and improves the position control accuracy of the photovoltaic panel rotation, thereby improving the efficiency of photovoltaic power generation. The photovoltaic power generation rack and unit with quasi-stepless adjustment function are described in detail below in conjunction with Figures 1 to 6.

[0052] In one embodiment, a photovoltaic power generation rack 900 with a quasi-stepless adjustment function is shown in FIG1, which includes a tracking component 200, a mounting seat 400 and an adjustment component 500; the tracking component 200 and the adjustment component 500 are respectively arranged on the mounting seat 400, and the mounting seat 400 is used as a base for installation, and the photovoltaic power generation rack 900 can be installed in an external environment; in conjunction with FIG2, the adjustment component 500 is used to connect the photovoltaic power generation panel 100; the tracking component 200 is used to track sunlight to cooperate with the adjustment component 500 to adjust the photovoltaic power generation panel 100 to a position aligned with the sun, so as to obtain a higher efficiency of photovoltaic power generation. Such a structural design, through the cooperation of the tracking component 200 and the adjustment component 500, drives the position adjustment of the adjustment component 500 based on the sunlight, thereby adjusting the position of the photovoltaic power generation panel 100, so that the photovoltaic power generation panel 100 has a quasi-stepless adjustment function and always accurately aligns with the sun, so it is called a photovoltaic power generation rack 900 with a quasi-stepless adjustment function.

[0053] In one embodiment, a photovoltaic power generation group 999 with a quasi-stepless adjustment function is shown in FIG2, which includes a photovoltaic power generation panel 100 and a photovoltaic power generation rack 900 with a quasi-stepless adjustment function described in any embodiment. In conjunction with FIG3, the photovoltaic power generation panel 100 is arranged on the adjustment component 500 of the photovoltaic power generation rack 900. It can be understood that because the photovoltaic power generation group 999 with a quasi-stepless adjustment function adopts the photovoltaic power generation rack 900 with a quasi-stepless adjustment function described in any embodiment, the photovoltaic power generation group 999 with a quasi-stepless adjustment function also has the beneficial technical effects of the photovoltaic power generation rack 900 with a quasi-stepless adjustment function, which will not be elaborated here.

[0054] In this embodiment, the photovoltaic power generation rack 900 with a quasi-stepless adjustment function further includes a bracket 910 disposed on the mounting seat 400, and the bracket 910 is used to connect the photovoltaic power generation panel 100; the photoresistor 201 is disposed on the bracket 910, and the adjustment assembly 500 is connected to the bracket 910. Further, in one embodiment, the photovoltaic power generation panel 100 is disposed on the bracket 910.

[0055] In one embodiment, as shown in FIG. 4 , the mounting base 400 includes an outer shell 410 and a sealing plate 420 , and the outer shell 410 is provided with an inner cavity 430 . Such a structural design, on the one hand, allows part of the tracking component 200 and part of the adjustment component 500 to be disposed in the inner cavity 430 , thereby avoiding adverse effects such as erosion by wind and rain and oxidation by sunlight, and ensuring the design life of the photovoltaic power generation rack 900 ; on the other hand, it is beneficial to flexibly control the shape, such as the height, of the photovoltaic power generation rack 900 through the shape of the outer shell 410 .

[0056] In one of the embodiments, as shown in FIG. 3 and FIG. 4 , the tracking component 200 or its photoresistor 201 is disposed on the adjusting component 500 and is disposed on the mounting seat 400 through the adjusting component 500; or, in other embodiments, the tracking component 200 is directly disposed on the mounting seat 400. In each embodiment, as shown in FIG. 5 , the tracking component 200 includes a photoresistor 201, a servo motor 202 and a transmission rod 203, the photoresistor 201 is conductively connected to the servo motor 202, the output end of the servo motor 202 is transmission-connected to the transmission rod 203, and the transmission rod 203 is connected to the adjusting component 500; the photoresistor 201 drives the position of the adjusting component 500 through the servo motor 202 and the transmission rod 203 to adjust the position of the photovoltaic panel 100. Exemplarily, in this embodiment, the number of the photoresistors 201 is two. Such a structural design is conducive to accurately and effectively sensing the direction of the sun, that is, the position of sunlight, through the photoresistor 201. When the sun's light is unevenly irradiated on the surface of the photovoltaic panel 100, the photoresistor 201 drives the servo motor 202 according to the light, and drives the adjustment component 500 to adjust the position of the photovoltaic panel 100 through the transmission rod 203.

[0057] In order to facilitate the support of the servo motor 202, in one embodiment, as shown in Figure 4, the photovoltaic power generation rack 900 with a quasi-stepless adjustment function also includes a support block 600 fixedly connected to the bottom of the servo motor 202, and the support block 600 is arranged on the mounting seat 400; further, by designing the shape of the support block 600, it is also beneficial to protect the servo motor 202.

[0058] In order to ensure that the photoresistor 201 can enable the photovoltaic panel 100 to track the sun and obtain a relatively high power generation efficiency, in one embodiment, the photoresistor 201 has the same light receiving direction as the photovoltaic panel 100. Such a structural design is conducive to the photoresistor 201 driving the adjustment component 500 to adjust the position of the photovoltaic panel 100 with the light, so that the photovoltaic panel 100 has a quasi-stepless adjustment function and is always accurately aligned with the sun, thereby enabling the photovoltaic panel 100 to track the sun and improving the position control accuracy of the photovoltaic panel 100 rotation, thereby improving the efficiency of photovoltaic power generation.

[0059] For the embodiment with the inner cavity 430, in one embodiment, in combination with FIG. 3 and FIG. 4, the servo motor 202 and the transmission rod 203 are disposed in the inner cavity 430 of the housing 410, the adjustment assembly 500 is at least partially disposed in the inner cavity 430, the sealing plate 420 is detachably disposed on the housing 410 to close the inner cavity 430; the photoresistor 201 is disposed on the housing 410. Such a structural design, as described above, allows part of the tracking assembly 200 and part of the adjustment assembly 500 to be disposed in the inner cavity 430, providing additional protection to ensure the design life of the photovoltaic power generation rack 900.

[0060] In one embodiment, as shown in FIG3 and FIG4, the adjustment component 500 is slidably disposed in the mounting seat 400 or its housing 410, and has a partial structure exposed from the mounting seat 400 or its housing 410, so as to directly or indirectly connect to the photovoltaic power generation panel 100; or in other embodiments, the adjustment component 500 is slidably disposed on the mounting seat 400. Such a structural design is conducive to adjusting the position of the photovoltaic power generation panel 100 on the one hand, and is conducive to protecting the adjustment component 500 on the other hand.

[0061] In one embodiment, as shown in FIG6 and FIG7, the adjustment assembly 500 includes a rack bar 501, a rotating block 502 and a transmission belt 505; the rack bar 501 is slidably disposed on the mounting seat 400, the rotating block 502 is rotatably connected to the rack bar 501, and is connected to the bracket 910 or the photovoltaic panel 100; the transmission belt 505 is meshed with the rack bar 501, and the photoresistor 201 drives the transmission belt 505 to rotate through the servo motor 202 and the transmission rod 203, so as to drive the rack bar 501 to slide on the mounting seat 400, thereby directly adjusting the position of the photovoltaic panel 100, or changing the position of the photovoltaic panel 100 disposed on the bracket 910 by adjusting the position of the bracket 910. Further, in one embodiment, the adjustment assembly 500 or its rotating block 502 is abutted, magnetically adsorbed or screwed with the bracket 910 or the photovoltaic panel 100. Such a structural design is conducive to accurately controlling the position of the photovoltaic panel 100 by means of a gear transmission. Since it is a gear connection combined with a rotation connection, the quasi-stepless adjustment function is better enhanced, so that the photovoltaic panel 100 is always accurately aligned with the sun to obtain a higher power generation efficiency.

[0062] It should be noted that, taking into account the influence of factors such as cost control, system robustness and structural complexity, the context provides an embodiment in which the adjustment component 500 adopts a gear connection. Those skilled in the art can understand that, in addition to the gear connection, the adjustment component 500 can also adopt a guide rail structure to realize the photovoltaic power generation rack 900 with a quasi-stepless adjustment function in a sliding connection manner, or adopt a stepping motor to realize the photovoltaic power generation rack 900 with a quasi-stepless adjustment function in a gradual lifting manner. The embodiments of the present application do not impose any restrictions on this.

[0063] Exemplarily, in this embodiment, the number of the rack rods 501 and the rotating blocks 502 is a pair, and the adjustment assembly 500 also includes a first gear 503, a second gear 504, a third gear 506 and a fourth gear 507; each of the rack rods 501 is connected to the bracket member 910 or the photovoltaic panel 100 through a rotating block 502; the transmission rod 203, the first gear 503 and the second gear 504 are coaxially fixedly connected; the third gear 506 and the fourth gear are coaxially fixedly connected; one of the rack rods 501 is slidably set on the mounting seat 400, and is also meshed with the first gear 503, and is meshed with the transmission belt 505 through the second gear 504; the other rack rod 501 is fixedly set on the mounting seat 400, and is also meshed with the third gear 506, and is meshed with the transmission belt 505 through the fourth gear 507. In other embodiments, the two rack rods 501 can also be slidably disposed on the mounting seat 400. Such a structural design, as mentioned above, by setting the tracking component 200, when the sun's light is unevenly irradiated on the surface of the photovoltaic panel 100, the intensity and direction of the current flowing into the servo motor 202 are changed through the photoresistors 201 on both sides, so that the transmission rod 203 drives the adjustment component 500 to make the photovoltaic panel 100 always face the sun, so that the photovoltaic power generation rack 900 with a quasi-stepless adjustment function can drive the photovoltaic panel 100 to track the sun, thereby improving the efficiency of photovoltaic power generation; and by setting the adjustment component 500, when the transmission rod 203 rotates, it drives the first gear The rotation of 503 changes the sliding of the rack rod 501 meshing with it, and at the same time, the second gear 504 drives the third gear 506 to rotate through the transmission belt 505, so that the fourth gear 507 drives the other rack rod 501 meshing with it to slide in the opposite direction, so that there is a height difference between the two rack rods 501, and at the same time, the photovoltaic panel 100 changes the angle through the rotating block to cooperate with the movement of the rack rod 501, so that the photovoltaic power generation rack 900 with a quasi-stepless adjustment function can perform quasi-stepless adjustment to make the photovoltaic panel 100 accurately align with the sun, thereby improving the rotation flexibility of the photovoltaic panel 100.

[0064] In one embodiment, as shown in FIG. 4 and FIG. 6 , the photovoltaic power generation rack 900 with a quasi-stepless adjustment function further includes a round rod 800, the two ends of which are respectively fixed to the mounting seat 400 or its housing 410, and the round rod 800 passes through the third gear 506 and the fourth gear 507, and is fixed to the third gear 506 and the fourth gear 507; one of the rack rods 501 is slidably disposed on the mounting seat 400, and is also meshed with the first gear 503, and is meshed with the transmission belt 505 through the second gear 504; the other rack rod 501 is fixedly disposed on the mounting seat 400, and is also meshed with the third gear 506, and is meshed with the transmission belt 505 through the fourth gear 507. In other embodiments, two rack rods 501 may be slidably disposed on the mounting seat 400. With such a structural design, on the one hand, the photovoltaic panel 100 can achieve a certain degree of rotation along with the two rack rods 501 under the action of the photoresistor 201, so that the photovoltaic panel 100 can track the sun along the sunlight; on the other hand, under the action of the round rod 800, the supporting effect of the third gear 506 and the fourth gear 507 is improved, so that more photovoltaic panels 100 of different specifications can be adapted.

[0065] In one embodiment, as shown in FIG4 , the photovoltaic power generation rack 900 with a quasi-stepless adjustment function further includes a bent rod 700, and the bent rod 700 and the adjustment assembly 500 are used to respectively connect the photovoltaic power generation panel 100. For an embodiment with a bracket 910, the bent rod 700 and the adjustment assembly 500 are used to respectively connect the bracket 910, that is, the photovoltaic power generation panel 100 is indirectly connected through the bracket 910 as an intermediate member. Exemplarily, the photovoltaic panel 100 and the photoresistor 201 are both arranged on a bracket 910, one end of the bracket 910 is rotatably connected to the support rod 300, and the other end is rotatably connected to the curved rod 700; the two rack rods 501 of the adjustment assembly 500 are connected to the bracket 910 one by one through two rotating blocks 502, and the photoresistor 201 drives any rack rod 501 to slide up and down. In this state, the rack rod 501 drives the bracket 910 to rotate coaxially along the support rod 300 and the curved rod 700, thereby driving the photovoltaic panel 100 to rotate to track the sun.

[0066] In one embodiment, as shown in FIG. 3 and FIG. 4, the photovoltaic power generation rack 900 with a quasi-stepless adjustment function further includes a support rod 300 disposed on the mounting seat 400, and the support rod 300 is used to rotatably connect the photovoltaic power generation panel 100; the adjustment assembly 500 is used to adjust the position of the photovoltaic power generation panel 100 so that the photovoltaic power generation panel 100 rotates on the support rod 300. In one embodiment, as shown in FIG. 3 and FIG. 4, the photovoltaic power generation rack 900 with a quasi-stepless adjustment function further includes a support rod 300 disposed on the mounting seat 400, and the support rod 300 is used to rotatably connect the bracket 910. Exemplarily, in this embodiment, a design of a support rod 300 and a curved rod 700 can be adopted. In other embodiments, a pair of support rods 300 can also be adopted, or a pair of curved rods 700 can be adopted. For a photovoltaic panel 100 with a relatively large area, if only a support rod 300 is used, a relatively large mounting seat 400 is required; if a pair of curved rods 700 are used, or a design of a support rod 300 and a curved rod 700 is used, the mounting seat 400 can be appropriately smaller.

[0067] Next, we will continue to use Figures 1 to 7 to illustrate the photovoltaic power generation rack and photovoltaic power generation group with quasi-stepless adjustment function. A photovoltaic power generation group 999 with quasi-stepless adjustment function is shown in Figure 2, which includes a photovoltaic power generation rack 900 with quasi-stepless adjustment function as shown in Figure 1, and also includes a photovoltaic power generation panel 100. In this embodiment, a tracking component 200 is fixedly connected to the edge of the top of the photovoltaic power generation panel 100. By setting the tracking component 200, when the sun's light is unevenly irradiated on the surface of the photovoltaic power generation panel 100, the intensity and direction of the current flowing into the servo motor 202 are changed through the photoresistors 201 on both sides, so that the transmission rod 203 drives the adjustment component 500 to make the photovoltaic power generation panel always face the sun, so that the photovoltaic power generation device can make the photovoltaic power generation panel track the sun, thereby improving the efficiency of photovoltaic power generation.
