Fig. 1 to 18 show a preferred embodiment of the solar collector of the present application, which, like some conventional solar collectors, also includes a supporting frame 14, and a header and a plurality of (specifically eight) heat collecting tubes 10 supported on the supporting frame 14. The header is fastened with the supporting frame 14, the header comprises a water-flowing inner container 1 and a protective outer cover 2 arranged on the periphery of the inner container, and a plurality of (specifically eight) heat collecting pipe penetrating holes 2a uniformly distributed at intervals along the linear direction are formed in the cover wall of the protective outer cover 2. The inner container 1 is provided with a water inlet 101 and a water outlet 102 extending out of the protective outer cover 2, and the wall of the inner container 1 is provided with eight heat collecting pipe connecting holes 1a coaxially arranged with the eight heat collecting pipe inserting holes 2a respectively. One end of the heat collecting pipe 10 penetrates through the heat collecting pipe penetrating hole 2a of the protective outer cover 2 and extends into the heat collecting pipe connecting hole 1a of the inner container 1, so that the heat collecting pipe 10 is connected with the inner container 1.

In practical application, the water inlet 101 and the water outlet 102 of the inner container 1 are respectively connected to a water inlet pipeline and a water outlet pipeline to introduce flowable water into the inner container 1 of the header. The heat collecting pipe 10 absorbs heat of sunlight to heat water fed into the inner container 1.

The support frame 14 serves as a support carrier for the entire solar collector and is used for supporting the weight of the header, the collector tube and the following components.

Unlike conventional solar collectors: the support frame 14 further supports eight light reflecting plates 11, the eight light reflecting plates 11 are respectively arranged on radial side portions of the eight heat collecting tubes 10 in a one-to-one correspondence manner, and each light reflecting plate 11 can rotate around an axis of the corresponding heat collecting tube 10. That is, the reflective plates 11 are rotatably disposed instead of being fastened to the collector, and the rotation axis of each reflective plate 11 on the supporting frame 14 is exactly the tube axis of the corresponding heat collecting tube 10.

During operation, can adjust the angle of reflector panel 11 in real time according to the incident angle of sunlight to the solar ray that will pass through the thermal-collecting tube 10 outside and shoot to reflector panel 11 reflects to thermal-collecting tube 10, with the photic area who promotes the thermal-collecting tube, and then promotes this solar collector's light and heat conversion efficiency.

In order to realize the automatic control of the rotation of the reflector 11, the solar collector with the reflector 11 is further provided with a driving device in transmission connection with each reflector 11, which specifically comprises the following steps:

referring to fig. 3 to 13, each heat collecting tube insertion hole 2a is rotatably provided with a rotating tube 3. One end of the rotary drum 3 extends into the protective outer cover 2 (i.e. is located on the inner side of the outer surface of the protective outer cover), and the other end extends out of the protective outer cover 2 (i.e. is located on the outer side of the outer surface of the protective outer cover). Each drum 3 is coaxially fixed with a synchronous pulley 4 inside the protective housing 2. Each synchronous pulley 4 is in transmission connection through a synchronous belt 6 arranged in the protective outer cover 2. The synchronous belt 6 is driven by a motor 5 fixed in the protective outer cover 2, specifically, a power wheel 16 is coaxially fixed on an output shaft of the motor 5, and the power wheel 16 is meshed with the synchronous belt 6.

The reflector 11 is fixedly connected with the rotary drum 3. The heat collecting pipe 10 penetrates into the rotary drum 3 and is connected with the heat collecting pipe connecting hole 1a of the inner container 1.

During operation, motor 5 drive hold-in range 6 rotates, and hold-in range 6 drags each synchronous pulley 4 synchronous revolution that is connected with it meshing, and synchronous pulley 4 drives each rotary drum 3 fixed with it and rotates around thermal-collecting tube 10, and each rotary drum 3 drives eight fixed reflectors 11 with it and rotates to as much as possible reflection with sunshine to thermal-collecting tube 10.

As shown in fig. 3, 4, and 15-17, in the present embodiment, the reflector 11 and the drum 3 are fixedly connected in this way: the peripheral fixing hoop of the end of the rotating drum 3 extending out of the protective housing 2 (i.e. the other end of the rotating drum) is provided with a hoop 12, and the hoop 12 is provided with a reflecting plate fixing groove 1202a for connecting the reflecting plate 11. One end of the reflector 11 is fixedly inserted into the reflector fixing groove 1202 a. The other end of the reflector 11 is connected to a rotary support 15 mounted at the bottom of the support frame 14.

Further, the hoop 12 includes: a left half ring 1201 and a right half ring 1202 which are fastened and connected through screws, and a lantern ring 1203 which is connected with the left half ring 1201 into a whole and is sleeved outside the rotary drum 3. The reflector fixing groove 1202a is specifically formed in the right half ring 1202. The lantern ring 1203 integrally arranged on the left half ring 1201 can not only shield the annular gap between the rotary drum 3 and the protective outer cover 2, but also can sleeve the lantern ring 1203 on the periphery of the rotary drum 3 in advance as a support body of the left half ring 1201 during assembly, and then the right half ring 1202 and the reflector 11 are connected, so that the installation of the reflector 11 is facilitated.

Referring to fig. 1 to 3 again, the present embodiment is further provided with eight photovoltaic panels 13, the eight photovoltaic panels 13 are also respectively arranged on the radial side portions of the eight heat collecting pipes 10 in a one-to-one correspondence manner, and each photovoltaic panel 13 can rotate around the axis of the corresponding one heat collecting pipe 10.

Specifically, a photovoltaic panel fixing groove 1202b is formed on the right half ring 1202, and one end of the photovoltaic panel 13 is fixedly inserted into the photovoltaic panel fixing groove 1202 b. The other end of the photovoltaic panel 13 is connected to a rotary support 15 mounted at the bottom of the support frame 14.

The solar heat collector with the photovoltaic plate 13 has not only a photo-thermal water boiling function, but also a photovoltaic power generation function. During operation, when the heat collecting tube 10 is required to absorb solar energy to obtain heat, the photovoltaic panel 13 is rotated to the backlight side (i.e. the side away from the sunlight) of the heat collecting tube 10, the heat collecting tube is exposed to light to generate heat, and the heat collecting tube operates in a photo-thermal mode. When photovoltaic power generation is needed, the photovoltaic panel 13 is rotated to the light-facing side (i.e. the side facing the sunlight) of the heat collecting tube 10, at this time, the photovoltaic working surface of the photovoltaic panel 13 just faces the sunlight and is in a working state, the photovoltaic panel 13 faces the light for power generation, and the heat collector works in a photovoltaic power generation mode.

The wall of the protective housing 2 is mainly composed of three parts, which are an inner wall 201, an outer wall 202, and a housing wall main body 203. The housing wall body 203 has a C-shaped cross section with a long opening 203 a. The inner wall 201 is detachably attached to the cover wall main body 203 at the opening 203a by screws, and closes the opening 203 a. The outer wall 202 is detachably connected to the outside of the inner wall 201 by screws. The screws connecting the inner wall 201 and the cover wall main body 203 and the screws connecting the inner wall 201 and the outer wall 202 are the same set of screws. The heat collecting pipe insertion hole 2a penetrates both the inner wall 201 and the outer wall 202. The synchronous pulley 4 and the synchronous belt 6 are uniformly arranged between the inner wall 201 and the outer wall 202.

The main moving parts of the driving device are hidden inside the protective outer cover 2, particularly between the outer wall and the inner wall of the protective outer cover, so that not only is the safety improved, but also the compactness of the solar heat collector is improved.

In order to ensure that each synchronous pulley 4 is always connected with the synchronous belt 6 in the working process, a tension pulley 7 connected with the synchronous belt 6 is arranged between the inner wall 201 and the outer wall 202. The wheel seat of the tension wheel 7 is connected with the inner wall 201 of the protective outer cover 2.

In order to better support the rotation of the drum 3, the present embodiment is further fixedly provided with a support sleeve 8 positioned at the periphery of the drum 3 between the inner wall 201 and the outer wall 202, and a support ball 9 is arranged between the support sleeve 8 and the drum 3.

Further, the support sleeve 8 is constituted by an inner sleeve 801 and an outer sleeve 802 detachably connected by a latch, and the inner sleeve 801 and the outer sleeve 802 are arranged in this order along the axial direction of the drum 3. The timing pulley 4 is fixed to the outer periphery of the drum 3, and the timing pulley 4 is accommodated between the inner sleeve 801 and the outer sleeve 802.
