DETAILED DESCRIPTION

[0026] The above and other embodiments and advantages of the present invention are described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments.

[0027] In one embodiment, if Figure 1-Figure 5 As shown:

[0028] This embodiment provides a solar photovoltaic thermal system, including an assembly frame 1, a photovoltaic device 2, a heating part 3, an inverter 4, an induction part 5, an electric shock part 6, and a wading component 7;

[0029] The photovoltaic device 2 includes a photovoltaic panel 21 fixed in the assembly rack 1, an inverter 4 fixed on the assembly rack 1 and located at the bottom side of the photovoltaic panel 21, and the photovoltaic device 2 also includes a circuit and a control part connecting the photovoltaic panel 21 and the inverter 4, and the control part includes a remote control device; the heating part 3 includes a wire connected to the inverter 4, and a heating plate 31 connected to the wire, the circuit and the control part;

[0030] One end of the assembly rack 1 is tilted upward, and the other end is tilted downward. The induction part 5 includes a swing frame 51 installed at the upper end of the assembly rack 1 and a lamp 52 installed on the swing frame 51. The electric shock part 6 includes a power grid 61 connected to the swing frame 51, and also includes a push switch 62 fixed on the assembly rack 1 and located above the photovoltaic panel 21. The output end of the push switch 62 is electrically connected to the push switch 62 to control the lamp 52. The input end of the push switch 62 is connected to the inverter 4. The push switch 62 and the swing frame 51 are in the same straight line. A motor for driving the swing frame 51 to rotate up and down is fixed on the assembly rack 1. When the swing frame 51 rotates to the assembly rack 1, it presses on the push switch 62 and triggers the push switch 62 to turn on. The push switch 62 controls the lamp 52 and the power grid 61 to work;

[0031] The wading assembly 7 includes a deflector 71 fixed on the inclined low end of the assembly frame 1 and a wading pipe 72 fixed at the bottom end of the deflector 71. The top end of the deflector 71 reaches the top surface of the photovoltaic panel 21, the bottom end of the wading pipe 72 is inserted into the water, and the heating plate 31 is inserted into the water and close to the bottom end of the wading pipe 72.

[0032] There are a plurality of lamp tubes 52 , with gaps 53 between the lamp tubes 52 . Bright light emitted by the lamp tubes 52 passes through the gaps 53 and the meshes of the electric grid 61 .

[0033] Working principle and effect: The photovoltaic panel 21 absorbs solar energy, converts it into electrical energy and stores it in the storage battery. After being processed by the inverter 4, it is sent to the control part by the circuit. After being processed by the controller in the control part, it is applied to the load. The load in the present invention is the lamp 52, the power grid 61, the push switch 62 and the heating plate 31. During the day, it is driven by the motor and the swing frame 51 is pressed. Figure 1 As shown, the power grid 61 rotates downward, the swing frame 51 is away from the push switch 62, the push switch 62 is powered off, and the power grid 61 and the light tube 52 are powered off. At this time, only the photovoltaic panel 21 works and is used to convert electrical energy and store it in the battery or apply it to the heating plate 31 to heat water. At night, the motor is powered on by the motor, which drives the swing frame 51 to press the switch 62. Figure 2 The electric grid 61 is rotated upwards as shown, and at the same time, the swing frame 51 is pressed on the push switch 62 (or called a moment switch, button, etc.), the normally open contact of the push switch 62 is closed, and the light tube 52 and the electric grid 61 are controlled to be powered on, the light tube 52 emits light at night to lure mosquitoes, and the electric grid 61 provides an electric shock effect at night, the mosquitoes fly to the light tube 52, and after being killed by the electric grid 61, they either fall on the electric grid 61, or after being killed, they pass through the mesh of the electric grid 61 and the gap 53 between the two light tubes 52 and fall on the photovoltaic panel 21, and the photovoltaic panel 21 is assembled The frame 1 is fixed above the water surface in an inclined manner. Therefore, in addition to meeting the requirements of solar energy absorption, the tilt of the photovoltaic panel 21 is also used to make the mosquito corpses slide along the inclined surface of the photovoltaic panel 21 or the power grid 61 to the water surface, and are used for fish feeding in the form of a food chain. It also protects the environment. The photovoltaic panel 21 is still working at this time, and is used to convert electric energy into electricity and store it in the battery, or is used on the heating plate 31 to heat water. Of course, during the actual assembly, the control components also include an automatic temperature control function to automatically adjust the water temperature.

[0034] In addition to the above, the heating plate 31 is close to the wading component 7, and the wading pipe 72 in the wading component 7 is inserted into the water, and the guide cover 71 at the top of the wading pipe 72 is exposed above the water surface. Since the top of the guide cover 71 is flush with the inclined lower end of the photovoltaic panel 21, the sliding mosquito corpses will fall into the guide cover 71, and then be collected by the guide cover 71 and fall into the wading pipe 72, and finally fall into the deep water from the bottom of the wading pipe 72, and be fed by fish in the first time. Compared with the existing application only in household heating or hot water supply, the application scope of photothermal has been expanded.

[0035] In addition to the above, since the heating plate 31 is close to the wading pipe 72, a connecting rod structure 8 is hinged on the heating plate 31, and the other end of the connecting rod structure 8 is connected to the outer unit tube 722, so that the heating plate 31 is arranged close to the wading pipe 72, and the heating plate 31 is bent toward the wading pipe 72, so the temperature in the water area involved by the wading pipe 72 is milder than that in other water areas, which is more suitable for fish to gather here. In addition, the electrocuted mosquitoes are discharged into the water area from the bottom end of the wading pipe 72, so it is more convenient for fish to feed nearby. A notch 311 is provided on the bottom side of the heating plate 31, and there are a plurality of notches 311, and the plurality of notches 311 are equidistantly provided along the arc direction of the heating plate 31, and a large number of notches 311 increase the heating area of ​​the heating plate 31 and improve the induction effect.

[0036] In addition to the above, if Figure 1 , Figure 3 As shown, the swing frame 51 is provided with an installation opening 511, the lamp tube 52 is installed within the opening range of the installation opening 511, the gap 53 is connected to the installation opening 511, and the installation opening 511 and the power grid 61 are symmetrically located on both sides of the lamp tube 52. Figure 2 As shown, when the electric grid 61 rotates upward, the installation opening 511 will flip downward and face the photovoltaic panel 21. After being killed by the electric grid 61, the mosquitoes will either directly slide along the surface of the electric grid 61 to the photovoltaic panel 21, and then slide from the photovoltaic panel 21 to the air guide cover 71, or pass through the mesh and the gap 53 between the two lamp tubes 52 and fall from the installation opening 511 to the photovoltaic panel 21, and then slide from the photovoltaic panel 21 into the air guide cover 71, and finally be collected in the air guide cover 71 and completely discharged into the water through the wading pipe 72.

[0037] like Figure 2 As shown, both sides of the top of the assembly rack 1 extend upward beyond the top surface of the photovoltaic panel 21, one end of the assembly rack 1 extends close to the swing frame 51, and the other end of the assembly rack 1 extends to the guide cover 71. The guide cover 71 is a trapezoidal cover with a large opening at the upper end and a gradually smaller opening at the lower end, which improves the discharge efficiency of mosquito corpses into the wading pipe 72.

[0038] In another embodiment, if Figure 2 , Figure 3As shown, the wading pipe 72 is a combined pipe consisting of an inner unit pipe 721 and an outer unit pipe 722, that is, the wading pipe 72 is a telescopic pipe consisting of an inner unit pipe 721 and an outer unit pipe 722, the inner unit pipe 721 is sleeved in the outer unit pipe 722, a guide groove 723 is provided on the outer unit pipe 722 along the length direction, the top end of the outer unit pipe 722 is fixed on the guide cover 71, a guide rod 724 is fixed on the top of the outer wall of the inner unit pipe 721, the guide rod 724 is slidably fitted in the guide groove 723, and a load bearing is fixed on the bottom end of the outer wall of the outer unit pipe 722. Ring 725, the outer unit tube 722 is covered with a telescopic sleeve 726, the bottom end of the telescopic sleeve 726 is limited on the top surface of the carrier ring 725, the top end of the telescopic sleeve 726 is limited on the bottom of the guide rod 724, when the inner unit tube 721 descends, the top end of the telescopic sleeve 726 is squeezed by the guide rod 724, so that the telescopic sleeve 726 is compressed and shortened, a float 727 is fixed to the bottom end of the inner unit tube 721, and a drop hole 728 is opened on the float 727 and communicated with the inner unit tube 721 from top to bottom, the float 727 is spherical, and the drop hole 728 is opened on the float 727 along the spherical annular array. In this embodiment, the float 727 falls on the water surface, and under the buoyancy of the float 727, the inner unit tube 721 rises along the outer unit tube 722. At this time, the telescopic sleeve 726 is compressed and shortened. When the water level drops, the telescopic sleeve 726 will release its length. At the same time, the inner unit tube 721 will bring the float 727 down, and the float 727 always floats on the water surface. In this embodiment, the electrocuted mosquito corpses enter the outer unit tube 722, then enter the inner unit tube 721, and then enter the float 727 from the inner unit tube 721, and finally fall directly on the water surface from the float 727. In this embodiment, since the wading tube 72 is a telescopic structure composed of a double-layer sleeve, it can automatically adjust its length according to the water level. Although the float 727 cannot be directly inserted into the water, the mosquito corpses can still be sprinkled on the water surface for fish to eat nearby.

[0039] In addition, during the day, the motor drives the swing frame 51 to Figure 1 As shown, the power grid 61 is rotated downward, the swing frame 51 no longer presses the push switch 62, and the normally open contact of the push switch 62 is automatically disconnected, the control power grid 61 and the lamp 52 are automatically powered off, and the photovoltaic panel 21 works normally and stores the converted electrical energy in the battery, or applies it to the heating plate 31 to heat the water as usual.

[0040] It is worth noting that: the solar photovoltaic product is not just one set, but multiple sets are added according to the implementation area of ​​the water area. In this way, there will be a photovoltaic panel 21 cooperating with multiple power grids 61 to improve the mosquito killing effect, there will be multiple wading pipes 72 inserted in the water area to improve the water temperature effect, and there will be multiple heating plates 31 inserted into the water area near the wading pipes 72 to improve the mosquito feeding effect.

This implementation scheme is only for the convenience of describing the scheme, and the orientations are described relatively with reference to the figures. In essence, the specific orientations of the components are described according to their actual installation and actual use as well as the customary orientations of technicians in this field.
