Description

Technical Field

[0001] The utility model relates to the technical field of solar collectors, in particular to a plate-type solar collector capable of generating electricity. Background Technique

[0002] The flat-plate collector is a low-temperature solar energy product with early and wide applications. The flat-plate collector mainly consists of a heat-absorbing plate, a heat-insulating layer, a housing and a transparent cover plate. The heat-absorbing plate is the main component of the flat-plate collector, which absorbs the solar radiation energy and transfers the heat to the heat transfer working medium (water). The heat-absorbing plate is composed of a row of pipes, a header pipe and a heat transfer flat plate. Several copper pipes are laid flat to form the row of pipes, and both ends are welded to the header pipe.

[0003] Currently, in order to make full use of solar energy, some solar collectors replace the transparent cover plate that protects the heat-absorbing plate with a power generation glass. The sunlight can directly irradiate the power generation glass for power generation, and part of the sunlight can also pass through the power generation glass to irradiate the heat-absorbing plate to heat the water. However, in this way, since the power generation glass absorbs part of the solar energy, when the sunlight is insufficient, the power generation glass still absorbs the solar energy, resulting in the failure to meet the main requirement of the collector (heating the water to a suitable temperature), so the use experience is not good. Content of the Utility Model

[0004] Aiming at the deficiencies existing in the prior art, the purpose of the utility model is to provide a plate-type solar collector capable of generating electricity, so as to solve the technical problems mentioned in the above background technique.

[0005] The above technical purpose of the utility model is achieved through the following technical solutions:

[0006] A plate-type solar collector capable of generating electricity, including a front fixing plate and a rear fixing plate. A water tank is fixedly connected to the tops of the front fixing plate and the rear fixing plate. A sealing frame is fixedly connected to one side of the front fixing plate. A heat-absorbing plate is fixedly connected to the side wall of the front fixing plate inside the sealing frame. A transparent cover plate assembly is arranged inside the sealing frame;

[0007] Rotating shells are rotatably connected to both opposite sides of the water tank. The side of the rotating shell close to the water tank is open. A driving part is arranged inside the rotating shell. A connecting rod is fixedly connected to the outer peripheral surface of the rotating shell. The ends of the two connecting rods far away from the rotating shell are fixedly connected to a power generation glass together.

[0008] Further, the driving part includes a servo motor fixedly connected to one side of the water tank. The servo motor is located inside the corresponding rotating shell. The output end of the servo motor is drivingly connected to a driving rod. One end of the driving rod away from the servo motor is fixedly connected to the inner wall of the rotating shell. A temperature sensor is fixedly connected to the bottom of the water tank. The probe of the temperature sensor extends into the water tank, and the temperature sensor is electrically connected to both servo motors.

[0009] Further, a buffer pad is fixedly connected to the side wall of the rear fixing plate, and one side of the power generation glass is in contact with the buffer pad.

[0010] Further, the transparent cover plate assembly includes a plurality of transparent plates. The side walls of two adjacent transparent plates are in contact with each other, and the outer wall of the transparent cover plate assembly is in contact with the inner wall of the sealing frame. An adjusting part is arranged between the transparent cover plate assembly and the front fixing plate.

[0011] Further, the adjusting part includes two long plates arranged between the front fixing plate and the transparent cover plate assembly. A plurality of electric push rods are fixedly connected to the side wall of the front fixing plate. The output ends of the corresponding plurality of electric push rods are fixedly connected to the corresponding long plates. A plurality of fixing rods are fixedly connected to the side wall of the front fixing plate. One end of the fixing rod away from the front fixing plate is hinged to the corresponding transparent plate, and the fixing rod slides through the long plate. A plurality of rotating rods are hinged to the side of the long plate close to the transparent plate. One end of the rotating rod away from the long plate is hinged to the corresponding transparent plate.

[0012] In summary, the present utility model includes at least one of the following beneficial technical effects:

[0013] 1. For this plate-type solar energy collector capable of generating electricity, in the initial state, the power generation glass does not shield the heat absorption plate, and sunlight directly irradiates the heat absorption plate to heat the water in the water tank. When the water temperature in the water tank rises to an appropriate temperature, the servo motor works to drive the power generation glass to rotate. The power generation glass is in contact with the sealing frame. At this time, most of the sunlight passes through the power generation glass for power generation, and a small part passes through the power generation glass and acts on the heat absorption plate to keep the water in the water tank warm, so as to ensure that sunlight fully acts on water heating when sunlight is insufficient and improve the use experience.

[0014] 2. For this plate-type solar energy collector capable of generating electricity, when the power generation glass is in contact with the sealing frame, the electric push rods work to drive a plurality of transparent plates to rotate, so that the transparent plates become vertical. At this time, the sunlight passing through the power generation glass irradiates the heat absorption plate through the gap between the two transparent plates, and there is no need to pass through the transparent plates and be lost, thereby improving the sunlight utilization efficiency.

Specific embodiments

[0021] The following will further describe the present utility model in detail with reference to the drawings.

[0022] Embodiment:

[0023] Refer to Figures 1 to 4 , a plate-type solar collector capable of generating electricity disclosed by the present utility model includes a front fixing plate 1 and a rear fixing plate 2. A water tank 3 is fixedly connected to the top of the front fixing plate 1 and the rear fixing plate 2. A sealing frame 4 is fixedly connected to one side of the front fixing plate 1. A heat absorption plate 5 is fixedly connected to the side wall of the front fixing plate 1 inside the sealing frame 4. A transparent cover plate assembly 6 is arranged inside the sealing frame 4;

[0024] Rotating shells 7 are rotatably connected to both opposite sides of the water tank 3. One side of the rotating shell 7 close to the water tank 3 is open. A driving part 8 is arranged inside the rotating shell 7. A connecting rod 9 is fixedly connected to the outer peripheral surface of the rotating shell 7. The ends of the two connecting rods 9 far from the rotating shell 7 are fixedly connected to a power generation glass 10 together.

[0025] In this embodiment, the heat absorbed by the heat absorption plate 5 is transferred to the water tank 3 through the drain pipe and the header pipe, causing the water in the water tank 3 to heat up. This is a mature existing technology and will not be elaborated here.

[0026] In the initial state, the power generation glass 10 is attached to the rear fixing plate 2, the front fixing plate 1 faces the direction of sunlight, and the transparent cover plate assembly 6 and the sealing frame 4 cooperate to protect the heat absorption plate 5 to prevent dust from contacting the heat absorption plate 5.

[0027] In the initial state, sunlight passes through the transparent cover plate assembly 6 and acts on the heat absorption plate 5, causing the water temperature in the water tank 3 to rise. The transparent cover plate assembly 6 is made of transparent glass material. The power generation glass 10 is a cadmium telluride power generation glass with a light transmittance of 20%. The power generation glass 10 is attached to the rear fixing plate 2 to prevent the power generation glass 10 from shaking when the wind blows towards the power generation glass 10 due to the power generation glass 10 being suspended.

[0028] In a further preferred embodiment of the present invention, as Figure 2 shown, the driving part 8 includes a servo motor 81 fixedly connected to one side of the water tank 3. The servo motor 81 is located inside the corresponding rotating shell 7. The output end of the servo motor 81 is drivingly connected to a driving rod 82. One end of the driving rod 82 away from the servo motor 81 is fixedly connected to the inner wall of the rotating shell 7. A temperature sensor 83 is fixedly connected to the bottom of the water tank 3. The probe of the temperature sensor 83 extends into the water tank 3, and the temperature sensor 83 is electrically connected to both servo motors 81.

[0029] In this embodiment, when the water temperature in the water tank 3 rises to a certain level, the temperature sensor 83 monitors that the water temperature reaches the standard and controls the two servo motors 81 to work through the controller. The servo motor 81 works to drive the driving rod 82 and the rotating shell 7 to rotate. The rotating shell 7 drives the connecting rod 9 and the power generation glass 10 to rotate until the power generation glass 10 fits against the outer wall of the sealing frame 4, covering the sealing frame 4. At this time, most of the solar energy is used for power generation by the power generation glass 10, and a small part of the solar energy passes through the power generation glass 10 and the transparent cover plate assembly 6 and acts on the heat absorption plate 5 to keep the water in the water tank 3 warm.

[0030] A storage battery (not shown in the figure) is fixedly connected to the outer wall of the water tank 3. The storage battery is electrically connected to the power generation glass 10 and is used to collect the electric energy generated by the power generation glass 10.

[0031] In a further preferred embodiment of the present invention, as Figure 4 shown, a buffer pad 11 is fixedly connected to the side wall of the rear fixing plate 2. One side of the power generation glass 10 is attached to the buffer pad 11.

[0032] In this embodiment, in the initial state, the power generation glass 10 is attached to the buffer pad 11 to prevent the power generation glass 10 from being worn due to friction between the power generation glass 10 and the rear fixing plate 2.

[0033] In a further preferred embodiment of the present utility model, as Figure 3 shown, the transparent cover plate assembly 6 includes a plurality of transparent plates 61. The side walls of two adjacent transparent plates 61 are in contact with each other, and the outer wall of the transparent cover plate assembly 6 is in contact with the inner wall of the sealing frame 4. An adjusting portion 12 is provided between the transparent cover plate assembly 6 and the front fixing plate 1.

[0034] In a further preferred embodiment of the present utility model, as Figure 3 and Figure 4 shown, the adjusting portion 12 includes two long plates 121 provided between the front fixing plate 1 and the transparent cover plate assembly 6. A plurality of electric push rods 122 are fixedly connected to the side wall of the front fixing plate 1. The output ends of the corresponding plurality of electric push rods 122 are fixedly connected to the corresponding long plates 121. A plurality of fixing rods 123 are fixedly connected to the side wall of the front fixing plate 1. The end of the fixing rod 123 away from the front fixing plate 1 is hinged to the corresponding transparent plate 61, and the fixing rod 123 slidably passes through the long plate 121. A plurality of rotating rods 124 are hinged to the side of the long plate 121 close to the transparent plate 61. The end of the rotating rod 124 away from the long plate 121 is hinged to the corresponding transparent plate 61.

[0035] Furthermore, the electric push rod 122 is electrically connected to the temperature sensor 83. After the temperature sensor 83 controls the servo motor 81 to work through the controller, the controller then controls the electric push rod 122 to work.

[0036] In this embodiment, when the power generation glass 10 is attached to the sealing frame 4, the electric push rod 122 works to drive the long plate 121 to move towards the direction close to the front fixing plate 1. The long plate 121 drives the rotating rod 124 to rotate. The rotating rod 124 drives the corresponding transparent plate 61 to rotate with the end of the fixing rod 123 as the center of the circle, so that a gap is generated between two adjacent transparent plates 61. Therefore, the light passing through the power generation glass 10 will directly pass through the gap between the two transparent plates 61 and act on the heat absorption plate 5, instead of passing through the transparent cover plate assembly 6 to cause solar energy loss, improving the utilization rate of solar energy and ensuring the heat preservation effect of the water in the water tank 3.

[0037] The embodiments of the specific implementation manners are all preferred embodiments of the present utility model, and do not limit the protection scope of the present utility model accordingly. Therefore: All equivalent changes made according to the structure, shape, and principle of the present utility model shall be covered within the protection scope of the present utility model.
