[0026] According to an embodiment of the present invention, a new type of anti-freezing flat solar collector is provided.
[0027] Embodiment 1;
[0028] As Figure 1-7As shown in the figure, a new type of anti-freezing flat solar collector according to an embodiment of the present invention includes a collector structure 1. Solar panels 2 are installed at both ends of the collector structure 1. An anti-freezing structure 3 is connected to one side of the collector structure 1. The anti-freezing structure 3 is connected to a pressurizing structure 4. A fixing structure 5 is arranged in a matching manner on the anti-freezing structure 3. The collector structure 1 includes an outer frame 101, tempered glass 102, heat conduction tubes 103, a heat collection plate 104, a liquid outlet 105, and a liquid inlet 106. Tempered glass 102 is installed on one side of the outer frame 101. A liquid outlet 105 and a liquid inlet 106 are respectively connected to the two sides of the outer frame 101 adjacent to the tempered glass 102. Heat conduction tubes 103 are installed inside the outer frame 101 of the outer frame 101. The heat conduction tubes 103 are communicated with the liquid outlet 105 and the liquid inlet 106. A heat collection plate 104 is arranged in a matching manner on the heat conduction tubes 103. A heat insulation layer is filled inside the inner side of the outer frame 101. A fixing block 503 is fixedly connected to the back of the outer frame 101 of the collector structure 1. The heat collection plate 104 is used to absorb heat, and then conduct the heat to the heat conduction tubes 103, thereby heating the heat conduction medium in the heat conduction tubes 103. There are two groups of liquid outlets 105 and liquid inlets 106. Generally, only one group is used. The unused group of liquid outlets 105 and liquid inlets 106 are blocked by a sealing cover. The used liquid outlets 105 and liquid inlets 106 are respectively connected to a three-way valve. Electric control valves or manual valves are arranged in a matching manner in the two channels of the three-way valve, so that the valve opening can be adjusted electrically or manually. One of the channels of the three-way valve is connected to the first pair of interfaces 302 of the liquid collection bucket 301 of the anti-freezing structure 3 through a valve for anti-freezing.
[0029] The anti-freezing structure 3 includes a liquid collection bucket 301, a first pair of interfaces 302, a second pair of interfaces 303, a third pair of interfaces 304, and fixing holes 305. A first pair of interfaces 302 is connected to one side of the liquid collection bucket 301. A second pair of interfaces 303 is connected to the other side of the liquid collection bucket 301. A third pair of interfaces 304 is connected to one end of the liquid collection bucket 301. Fixing holes 305 are formed in the liquid collection bucket 301. There are two groups of liquid collection buckets 301 of the anti-freezing structure 3. The first pair of interfaces 302 of the two groups of liquid collection buckets 301 are respectively communicated with the liquid outlet 105 and the liquid inlet 106. The flow rate of the heat conduction medium can be adjusted through a valve. The second pair of interfaces 303 of the first liquid collection bucket 301 and the third pair of interfaces 304 between the second liquid collection bucket 301 are connected through a pressurizing structure 4. The liquid collection bucket 301 is conveniently fixed through a fixing structure 5. When anti-freezing is required, the valve is switched to connect the liquid collection bucket 301. Generally, the first liquid collection bucket 301 is placed at a high position, and the liquid in the liquid collection bucket 301 can flow through the height difference formed pressure, so that the heat conduction medium in the high-position liquid collection bucket 301 flows into the low-position liquid collection bucket 301 through the heat conduction tubes 103. Through the pressurizing structure 4, the high-position liquid collection bucket 301 can be pressurized, so as to increase the pressure difference with the low-position liquid collection bucket 301 and ensure the fluidity of the medium.
[0030] The pressurizing structure 4 includes a pressing airbag 401, a first one-way valve 402, and a second one-way valve 403. One end of the pressing airbag 401 is connected to the first one-way valve 402, and the other end of the pressing airbag 401 is connected to the second one-way valve 403. The pressing airbag 401 is docked with the third pair of interfaces 304 of the liquid collecting barrel 301 through the first one-way valve 402 and a pipeline. The pressing airbag 401 is oppositely docked with the second pair of interfaces 303 of another set of liquid collecting barrels 301 through the second one-way valve 403 and a pipeline. The first one-way valve 402 of the pressurizing structure 4 conducts upward, and the second one-way valve 403 also conducts upward. When the pressing airbag 401 is pressed, the inside of the airbag will be pressurized, and then the second one-way valve 403 will conduct to pressurize the inside of the high-level liquid collecting barrel 301. When the pressing airbag 401 returns, due to the low pressure, the first one-way valve 402 will conduct, and then the pressure will be balanced, reducing the internal pressure of the low-level liquid collecting barrel 301. As the heat-conducting medium in the high-level and low-level liquid collecting barrels 301 continuously flows, the pressure will gradually tend to be balanced. After that, the pressing airbag 401 can be squeezed again to increase the pressure, or by the convenient disassembly of the fixing structure 5, the high-level and low-level liquid collecting barrels 301 can be swapped to keep the high-level liquid collecting barrel 301 at a high position, so as to maintain the fluidity of the heat-conducting medium, prevent it from solidifying at low temperatures, and at the same time achieve the non-powered state during the flow of the heat-conducting medium, enabling it to have a good anti-freezing function in a non-electric environment.
[0031] The fixing structure 5 includes a rotating block 501, a rotating buckle 502, a fixing block 503, a rotating handle 504, and a fixing lock groove 505. One side of the rotating block 501 is fixedly connected to the rotating buckle 502. The rotating buckle 502 is connected to the fixing block 503. A fixing lock groove 505 is formed in the fixing block 503. The other side of the rotating block 501 is fixedly connected to the rotating handle 504. The fixing block 503 is fixed to one side of the outer frame 101. After aligning the fixing hole 305 of the liquid collecting barrel 301 with the fixing block 503 and inserting it, the rotating block 501 and the rotating buckle 502 are introduced into the fixing lock groove 505, and then rotated through the rotating handle 504 to make the rotating buckle 502 buckle in the fixing lock groove 505, completing the fixing of the liquid collecting barrel 301. When disassembly is required, rotate the rotating handle 504 in the opposite direction to complete the disassembly of the liquid collecting barrel 301, improving the convenience of installation and disassembly of the liquid collecting barrel 301.
[0032] To facilitate the understanding of the above technical solutions of the present invention, the working principle or operation method of the present invention in the actual process will be described in detail below.
[0033] In summary, by means of the above technical solution of the present utility model, a fixed block 503 is fixedly connected to the back of the outer frame 101 of the collector structure 1. The heat collecting plate 104 is used to absorb heat, and then conduct the heat to the heat conduction pipe 103, thereby heating the heat conduction medium in the heat conduction pipe 103. There are two sets of liquid outlets 105 and liquid inlets 106. Generally, only one set is used, and the unused set of liquid outlets 105 and liquid inlets 106 are blocked by a sealing cover. The used liquid outlets 105 and liquid inlets 106 are respectively connected to a three-way valve. Electric control valves or manual valves are respectively arranged in the two channels of the three-way valve, so that the valve opening can be adjusted electrically or manually. One of the channels of the three-way valve is connected to the first pair of interfaces 302 of the liquid collecting barrel 301 of the antifreeze structure 3 through a valve for antifreeze. There are two sets of liquid collecting barrels 301 of the antifreeze structure 3. The first pair of interfaces 302 of the two sets of liquid collecting barrels 301 are respectively communicated with the liquid outlet 105 and the liquid inlet 106. The flow rate of the heat conduction medium can be adjusted through the valve. The second pair of interfaces 303 of the first liquid collecting barrel 301 and the third pair of interfaces 304 between the second liquid collecting barrel 301 are connected through a pressurizing structure 4. The liquid collecting barrel 301 is conveniently fixed through a fixing structure 5. When antifreeze is required, the valve is switched to connect the liquid collecting barrel 301. Generally, the first liquid collecting barrel 301 is placed at a high position, and the liquid in the liquid collecting barrel 301 can flow through the pressure formed by the height difference, so that the heat conduction medium in the high-position liquid collecting barrel 301 flows to the low-position liquid collecting barrel 301 through the heat conduction pipe 103. Through the pressurizing structure 4, the high-position liquid collecting barrel 301 can be pressurized to increase the pressure difference with the low-position liquid collecting barrel 301 and ensure the fluidity of the medium. The first one-way valve 402 of the pressurizing structure 4 conducts upward, and the second one-way valve 403 also conducts upward. When the airbag 401 is pressed, the pressure inside the airbag will increase, and then the second one-way valve 403 will conduct to pressurize the high-position liquid collecting barrel 301 internally. When the airbag 401 returns after being pressed, due to the low air pressure, the first one-way valve 402 will conduct, and then the pressure will be balanced, so that the internal pressure of the low-position liquid collecting barrel 301 will be reduced. As the heat conduction medium in the high- and low-position liquid collecting barrels 301 continuously flows, the pressure will gradually tend to be balanced. Then, the airbag 401 can be squeezed again to increase the pressure, or the high- and low-position liquid collecting barrels 301 can be swapped by the convenient disassembly of the fixing structure 5, and the high-level liquid collecting barrel 301 is kept at a high position, so as to maintain the fluidity of the heat conduction medium, prevent it from solidifying at low temperature, and at the same time realize the non-powered operation during the flow of the heat conduction medium, so that it can have a good antifreeze function in a non-electric environment. The fixed block 503 is fixed on one side of the outer frame 101. After aligning the fixing hole 305 of the liquid collecting barrel 301 with the fixed block 503 and inserting it, the rotating block 501 and the rotating buckle 502 are introduced into the fixed locking groove 505, and then rotated through the rotating handle 504, so that the rotating buckle 502 is buckled in the fixed locking groove 505 to complete the fixing of the liquid collecting barrel 301. When disassembly is required, the rotating handle 504 is rotated in the opposite direction,The disassembly of the liquid collecting bucket 301 can be completed, improving the convenience of the installation and disassembly of the liquid collecting bucket 301.
[0034] The above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
