[0033] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and understandable, the following will describe the detailed implementation manners of the present invention in conjunction with the drawings. Many specific details are set forth in the following description in order to fully understand the present invention. However, the present invention can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the connotation of the present invention. Therefore, the present invention is not limited by the specific embodiments disclosed below

[0034] Refer to Figures 1 - 4 , a solar photovoltaic and solar thermal heat collection device, including a bottom plate 1, a fixing unit 2 is installed at the upper end of the bottom plate 1, and a plurality of uniformly distributed heat collection units 3 are connected to the fixing unit 2

[0035] Refer to Figure 1 , Figure 5 and Figure 6, the fixing unit 2 includes a water inlet frame 21 disposed above the bottom plate 1 and in an inclined state. A water inlet pipe is installed at the upper rear end of the right side of the water inlet frame 21. Guide rails 22 are symmetrically installed at the left end of the water inlet frame 21. A plurality of water pipes 23 are evenly distributed between the two guide rails 22 and fixedly connected to the water inlet frame 21.

[0036] Refer to Figure 1 and Figure 5 , the fixing unit 2 further includes a plurality of support plates 25 evenly distributed and respectively installed at the front and rear sides of the upper end of the bottom plate 1. The upper ends of the plurality of support plates 25 on the front and rear sides are respectively fixedly connected to the guide rails 22 on the front and rear sides. The structures of the plurality of support plates 25 on the front and rear sides are the same except for the height.

[0037] During specific operation, the bottom plate 1 is fixed at the working position. The bottom plate 1 supports the two guide rails 22 through two support plates 25 with different heights, so that the coplanarity of the two guide rails 22 is in an inclined state, which facilitates the subsequent contact between the heat collection unit 3 and sunlight. Then, the water inlet pipe on the water inlet frame 21 is connected to an existing water pump.

[0038] Refer to Figure 1 , Figure 2 , Figure 5 and Figure 8 , the heat collection unit 3 includes a plurality of installation frames 31 evenly distributed and slidably connected between the two guide rails 22. The installation frame 31 has a U-shaped structure with an opening facing obliquely upward. A heat insulation plate 32 located below the plurality of water pipes 23 is installed at the inner end of the middle section of the installation frame 31. A heat collection component 33 is connected inside the installation frame 31. The heat collection unit 3 further includes four connection seats 35 distributed in a rectangular shape and respectively installed at both ends of the opening of the installation frame 31. A clamping plate 36 is rotatably connected to the upper end of the connection seat 35.

[0039] Refer to Figure 1 , Figure 5 , Figure 8 and Figure 9 , the heat collection component 33 includes a heat collection module 331 inserted into the installation frame 31. Placement strips 332 are installed at both ends of the heat collection module 331 close to the two guide rails 22. A plug-in plate 333 is installed at the obliquely lower end of the placement strip 332. Guide openings 334 are provided at the opposite ends of the front and rear plug-in plates 333.

[0040] During specific operation, before use, splice the two placement bars 332 with the corresponding two mounting frames 31. The placement bar 332 drives the plug-in board 333 to penetrate through the middle section of the mounting frame 31. At the same time, the two placement bars 332 drive the heat collection module 331 to move into the mounting frame 31 until the placement bar 332 is closely attached to the open end of the mounting frame 31. Subsequently, rotate the four clamping plates 36 on the mounting frame 31 to the two ends of the two placement bars 332 to realize the function of limiting the two placement bars 332, and further realize the function of initially limiting the heat collection module 331. Repeat this step to realize the connection of multiple heat collection components 33 to the mounting frame 31. The heat collection module 331 mainly includes glass, a covering film, a solar cell, and an aluminum alloy heat absorption plate. The solar cell is provided with an output port for connecting to an external wire. The heat collection module 331 is modularly designed and is detachably connected to the mounting frame 31, and the installation and disassembly are simple and convenient, so as to facilitate the maintenance and care of the heat collection module 331.

[0041] Refer to Figure 1 , Figure 2 , Figure 6 and Figure 7 , at the ends of the two guide rods 22 far from the water inlet frame 21, a clamping member 24 is commonly connected. The clamping member 24 includes two limiting components 241 that are symmetrically distributed front and back and are respectively connected to the ends of the two guide rods 22. The limiting component 241 includes a limiting sleeve 2411 sleeved on the end of the guide rod 22 far from the water inlet frame 21. The limiting sleeve 2411 is of a stepped structure. The limiting sleeve 2411 is fixedly connected to the end of the water outlet frame 242. A locking screw 2412 is rotatably connected to the vertical end wall of the limiting sleeve 2411, and the locking screw 2412 is threadedly connected to the end of the guide rod 22.

[0042] Refer to Figure 1 , Figure 2 and Figure 5 , a plurality of the mounting frames 31 are in plug-in fit with the corresponding heat collection components 33, and then a plurality of the mounting frames 31 are slidably connected to the two guide rods 22. The two limiting components 241 are used to limit the plurality of mounting frames 31, and the pushing component 243 is used to push and press the pressing component 34 so that the heat collection component 33 is closely attached to the plurality of water pipes 23.

[0043] During specific operation, the mounting frames 31 after being connected to the corresponding heat collecting components 33 are sequentially and slidably connected to the two guide rods 22. When connecting, ensure that the heat collecting components 33 face obliquely upward. After multiple mounting frames 31 are connected to the two guide rods 22, the two limit sleeves 2411 are simultaneously sleeved on the ends of the two guide rods 22. Subsequently, rotate the locking screw 2412. The locking screw 2412 is threadedly connected to the guide rod 22 and drives the limit sleeve 2411 to move. The limit sleeve 2411 squeezes multiple mounting frames 31, causing multiple mounting frames 31 to fit towards the water inlet frame 21, avoiding gaps between multiple mounting frames 31, and there is no need to limit each mounting frame 31 through a large number of bolts, effectively reducing the difficulty of installing multiple mounting frames 31, reducing the installation steps, and improving the installation efficiency.

[0044] Refer to Figure 1 and Figure 7 Between the two limit components 241, a water outlet frame 242 is connected. On the inner end face of the right frame wall of the water outlet frame 242, a plurality of uniformly distributed and communicating sleeves 2421 are installed and communicate with it. The communicating sleeves 2421 are inserted and matched with the ends of the corresponding water pipes 23. A sealing ring is laid on the inner ring surface of the communicating sleeve 2421. A water outlet pipe is installed at the lower front side of the left end of the water outlet frame 242.

[0045] Refer to Figure 1 and Figure 7 At one end of the water inlet frame 21 and the water outlet frame 242 close to the heat collecting component 33, heat insulation layers are provided.

[0046] During specific operation, when the two limit sleeves 2411 are sleeved on the guide rod 22, they drive the water outlet frame 242 to move towards the plurality of water pipes 23 at the same time. The plurality of communicating sleeves 2421 on the water outlet frame 242 correspond to the plurality of water pipes 23 one by one and are inserted and matched with each other. The sealing ring in the communicating sleeve 2421 improves the sealing performance of the connection between the communicating sleeve 2421 and the end of the water pipe 23. After the limit sleeve 2411 limits the plurality of mounting frames 31, connect the existing drain pipe to the water outlet pipe on the water outlet frame 242. At this time, the plurality of water pipes 23 are located between the heat insulation plate 32 and the heat collecting module 331. The heat insulation layers on the water inlet frame 21 and the water outlet frame 242 and the plurality of heat insulation plates 32 and the plurality of heat collecting modules 331 form a heat preservation space, reducing the influence of the external temperature on the heat collection of the water pipes 23.

[0047] Refer to Figure 2 、 Figure 5 、 Figure 8 and Figure 9, two pressing components 34 are symmetrically connected to the outer end of the middle section of the installation frame 31. The pressing component 34 includes a guiding frame 341 installed at the lower inclined end of the installation frame 31 through a connecting column. A moving plate 342 is slidably connected inside the guiding frame 341. One end of the moving plate 342 close to the guide rail rod 22 is installed with a U-shaped frame 343 with an opening facing the guide rail rod 22. A pushing column 344 is installed inside the U-shaped frame 343. A circular protrusion is integrally formed at the end of the moving plate 342 away from the U-shaped frame 343. A square plate is installed at the upper inclined end of the moving plate 342. A return spring 345 is installed between the square plate and the connecting column.

[0048] Refer to Figure 1 , Figure 5 , Figure 7 and Figure 9 , a pushing component 243 is connected to the lower end of the water outlet frame 242. The pushing component 243 includes a first rectangular plate 2431 installed at the lower inclined end of the water outlet frame 242. A rectangular through hole 2433 is formed on the first rectangular plate 2431. A pushing plate 2434 is inserted into the rectangular through hole 2433. A plurality of uniformly distributed and right trapezoid-shaped pushing protrusions 2435 are installed at both the front and rear ends of the pushing plate 2434. The inclined surface of the pushing protrusion 2435 faces the moving plate 342. The right end of the pushing plate 2434 is slidably sleeved and connected with a second rectangular plate 2432. The second rectangular plate 2432 is fixedly connected to the lower inclined end of the water inlet frame 21.

[0049] Refer to Figure 1 and Figure 7 , the pushing component 243 further includes a pressing plate 2436 installed at the left end of the pushing plate 2434. A guiding plate 2437 slidably penetrating and mating with the first rectangular plate 2431 is installed at the right end of the pressing plate 2436. A connecting screw 2438 is threadedly connected at the lower end of the pressing plate 2436.

[0050] During specific operation, initially, the pushing plate 2434 is in a separated state from the first rectangular plate 2431 and the second rectangular plate 2432. After being limited by multiple mounting frames 31, the water outlet frame 242 limits the first rectangular plate 2431. Subsequently, the pushing plate 2434 is inserted into the rectangular through-hole 2433 and moves towards the second rectangular plate 2432 by pushing the pressing plate 2436. The guiding plate 2437 guides the movement of the pushing plate 2434. During the process of the pushing plate 2434 being inserted and engaged with the second rectangular plate 2432, the pushing plate 2434 drives multiple pushing protrusions 2435 on both sides to push the circular protrusions on the moving plates 342 on both sides. The moving plates 342 are stressed and drive the pushing columns 344 to move towards the guiding opening 334 on the plugging plate 333 through the U-shaped frame 343 and push the inclined lower side wall of the guiding opening 334. The plugging plates 333 on both sides are stressed and downwardly traction the heat collection module 331 through two placing strips 332 to ensure that the heat collection module 331 closely adheres to the water pipe 23, ensuring the heat collection effect of the water pipe 23. At the same time, the moving plates 342 squeeze the return spring 345 through the square plate. When the pushing plate 2434 is inserted and engaged with the second rectangular plate 2432, the connecting screw 2438 is rotated. The connecting screw 2438 is threadedly connected to the first rectangular plate 2431, and then the pushing plate 2434 is limited by the pressing plate 2436. Subsequently, the solar photovoltaic and solar thermal heat collection device is used normally.
