Specific embodiments

[0028] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0029] As Figures 1 to 10 shown, an energy-saving ventilation device for underground buildings according to an embodiment of the present invention includes a ventilation main body 1, a filtering assembly for filtering the air in the underground building; a siphon assembly for extracting the air by using the principle of thermosiphon; a refrigeration assembly for reducing the temperature of the air in the underground building; a flow-promoting assembly for promoting the air circulation speed. The filtering assembly includes a refrigeration bin 2 fixedly connected to one end of the bottom inner wall of the ventilation main body 1. And the bottom of the refrigeration bin 2 is fixedly connected with a ventilation pipe 3, and one end of the ventilation pipe 3 is fixedly connected with an air inlet housing 4. The top of the inner wall of the air inlet housing 4 is fixedly connected with an air inlet pipe 5, and the bottom of the outer wall of the air inlet pipe 5 is clamped with a filter bin 6. And a plurality of filter plates 7 are slidably connected to the inner wall of the filter bin 6. The bottom of the filter bin 6 is fixedly connected with a shunt air inlet plate 8. And both ends of the bottom of the shunt air inlet plate 8 are fixedly connected with handles 9. Both ends of the top of the shunt air inlet plate 8 are fixedly connected with support bases 10, and a connecting plate 11 is slidably connected to the inner wall of the support base 10. And the top of one side of the outer wall of the connecting plate 11 is rotatably connected to one side of the inner wall of the air inlet housing 4.

[0030] During operation, the air intake housing 4 is installed on the top of the underground building. Connecting plates 11 are provided at both ends of the inner wall of the air intake housing 4. Support bases 10 are provided on the outer walls of the connecting plates 11, and a split air intake plate 8 is provided at the bottom of the support bases 10. By pulling down the handles 9 provided at both ends of the bottom of the split air intake plate 8, the filter chamber 6 provided at the top of the split air intake plate 8 is disengaged from the air intake pipe 5 provided at the top of the inner wall of the air intake housing 4. At this time, push the handle 9 forward, so that the split air intake plate 8 and the filter chamber 6 are offset with the connecting plate 11 as the center, and a damping device is provided in the connecting plate 11, so that the split air intake plate 8 and the filter chamber 6 remain inclined. At this time, a number of filter plates 7 are inserted into the filter chamber 6, and the handle 9 is pushed to reset the split air intake plate 8 and the filter chamber 6. A ventilation pipe 3 is provided at the top of the air intake housing 4, and the ventilation pipe 3 extends to the roof. A ventilation main body 1 is installed on the roof, and one end of the ventilation pipe 3 is installed in the refrigeration chamber 2 provided at one end of the bottom of the inner wall of the ventilation main body 1. An exhaust chamber 12 is provided at the top of the ventilation main body 1, and a heat conduction pipe 14 is provided on one side of the inner wall of the exhaust chamber 12. By starting the semiconductor refrigeration plate 16 and using the liquid-cooled heat conduction chamber 15 provided on its heating surface, the heat is transferred into the heat conduction pipe 14, so that the temperature in the exhaust chamber 12 continues to rise. At this time, there is a temperature difference between the air in the exhaust chamber 12 and the air in the ventilation pipe 3. Using the thermosiphon phenomenon, the air in the ventilation pipe 3 continuously enters the exhaust chamber 12.

[0031] During this process, a number of filter plates 7 provided in the filter chamber 6 are used to filter the air in the underground building, so that the air enters the exhaust chamber 12 along the ventilation pipe 3 and is discharged through the exhaust pipe 13 provided at the top of the exhaust chamber 12, further solving the problem that the traditional energy-saving ventilation device for underground buildings is more complicated in structure and more cumbersome in daily maintenance during use; the daily maintenance work is simplified by the streamlined structure, improving the user experience.

[0032] The siphon assembly includes an exhaust chamber 12 fixedly connected to the top of the ventilation main body 1, and an exhaust pipe 13 is fixedly connected to the top of the exhaust chamber 12. A number of heat conduction pipes 14 are fixedly connected to one side of the inner wall of the exhaust chamber 12, and one end of the heat conduction pipe 14 is fixedly connected to a liquid-cooled heat conduction chamber 15, and a semiconductor refrigeration plate 16 is fixedly connected to the bottom of the liquid-cooled heat conduction chamber 15.

[0033] During operation, an exhaust air chamber 12 is provided at the top of the ventilation main body 1, and a heat conduction tube 14 is provided on one side of the inner wall of the exhaust air chamber 12. By starting the semiconductor refrigeration plate 16 and providing a liquid-cooled heat conduction chamber 15 on its heat-generating surface. Since the inside of the liquid-cooled heat conduction chamber 15 is filled with fluorinated liquid, and the end of the heat conduction tube 14 is in direct contact with the fluorinated liquid, the temperature generated on the heat-generating surface of the semiconductor refrigeration plate 16 is quickly absorbed by the fluorinated liquid. While achieving temperature reduction, the temperature is transferred into the heat conduction tube 14, creating a temperature difference between the air in the exhaust air chamber 12 and the air in the ventilation pipe 3, forming a thermosiphon phenomenon. Thus, through the ventilation pipe 3, the air in the underground building is sent into the exhaust air chamber 12 through the connecting pipe 19. At the same time, after the air is cooled in the refrigeration chamber 2, it enters the exhaust air chamber 12 and continuously blows towards the heat conduction tube 14. On the one hand, the heat conduction tube 14 cools the fluorinated liquid to prevent the temperature of the heat-generating surface of the semiconductor refrigeration plate 16 from being too high and thus being damaged. On the other hand, a large temperature difference is generated between the air discharged from the connecting pipe 19 and the air in the exhaust air chamber 12, making the thermosiphon phenomenon more stable.

[0034] Exemplarily, the refrigeration assembly includes a liquid storage chamber 17 fixedly connected to the bottom of one side of the inner wall of the ventilation main body 1, and one end of the top of the liquid storage chamber 17 is fixedly connected to the outer wall of the semiconductor refrigeration plate 16, and a plurality of refrigeration tubes 18 are fixedly connected to the bottom of the semiconductor refrigeration plate 16. The flow-promoting assembly includes a connecting pipe 19 fixedly connected to the top of the refrigeration chamber 2, and one end of the connecting pipe 19 is fixedly connected to one end of the bottom of the exhaust air chamber 12.

[0035] Exemplarily, a heat sink 20 is fixedly connected to the middle of the inner wall of the refrigeration chamber 2, and heat conduction blocks 21 are fixedly connected to both sides of the outer wall of the heat sink 20, and an annular pipe 22 is fixedly connected to one side of the outer wall of the heat conduction block 21.

[0036] Exemplarily, a partition plate 23 is fixedly connected to one end of the bottom of the inner wall of the liquid storage chamber 17, a liquid discharge port 24 is provided on one side of the outer wall of the partition plate 23, and a liquid inlet pipe 25 is fixedly connected to the end of the outer wall of the partition plate 23 away from the liquid discharge port 24. One end of the liquid inlet pipe 25 is fixedly connected to a water pump 26, and the input end of the water pump 26 is fixedly connected to one end of the annular pipe 22.

[0037] Exemplarily, a liquid discharge pipe 27 is fixedly connected to the end of the bottom of the inner wall of the liquid storage chamber 17 away from the partition plate 23, and one end of the liquid discharge pipe 27 is fixedly connected to the end of the annular pipe 22 away from the input end of the water pump 26. A collection pipe 28 is fixedly connected to the end of the bottom of the inner wall of the exhaust air chamber 12 away from the connecting pipe 19, and one end of the collection pipe 28 is fixedly connected to the top of the liquid storage chamber 17.

[0038] During operation, a liquid storage chamber 17 is arranged at the top on one side of the inner wall of the ventilation main body 1. A semiconductor refrigeration plate 16 arranged at one end of the top of the liquid storage chamber 17 is started, and a number of refrigeration pipes 18 are arranged at its refrigerating end. The refrigeration pipes 18 are used to continuously cool the coolant in the liquid storage chamber 17 (the coolant is composed of a mixture of water and alcohol and has a freezing point of -20°C). By arranging a drain pipe 27 at one end of the bottom of the inner wall of the liquid storage chamber 17, the coolant flows into the annular pipe 22 along the drain pipe 27. Since a heat sink 20 is arranged in the middle of the inner wall of the refrigeration chamber 2, and heat conduction blocks 21 are arranged on both sides of the outer wall of the heat sink 20. One end of the heat conduction block 21 is inside the annular pipe 22. Thus, when the coolant enters the annular pipe 22, the surface temperature of the heat sink 20 is reduced by the coolant through the heat conduction block 21. When the air discharged from the ventilation pipe 3 enters the refrigeration chamber 2, it passes through the heat sink 20, further reducing the temperature of the air, increasing the temperature difference between the exhaust air chamber 12 and the refrigeration chamber 2, making the thermosiphon phenomenon more obvious, and effectively increasing the air flow rate in the ventilation pipe 3 and improving the air extraction efficiency of the air inlet housing 4.

[0039] By arranging a water pump 26 at one end of the outer wall of the annular pipe 22 away from the drain pipe 27, the water pump 26 is used to pump the coolant that has circulated in the annular pipe 22 into the liquid inlet pipe 25 arranged at its output end. By arranging a partition plate 23 at one end of the bottom of the inner wall of the liquid storage chamber 17, and one side of the outer wall of the partition plate 23 is connected to the outer wall of the liquid inlet pipe 25, the coolant after circulation flows into one side of the partition plate 23 along the liquid inlet pipe 25. Since the partition plate 23 is on the side close to the refrigeration pipe 18 and divides the space in the liquid storage chamber 17 into a relatively small area, the discharged coolant can quickly contact the refrigeration pipe 18. The coolant that has been re-cooled is discharged through a drain port 24 arranged at one end of the outer wall of the partition plate 23 away from the liquid inlet pipe 25, thus completing the cold cycle of the refrigeration chamber 2. The discharged cold air enters the exhaust air chamber 12 along the connecting pipe 19 and contacts the heat conduction pipe 14, causing water vapor to be generated on the surface of the heat conduction pipe 14. Since the heat conduction pipe 14 has a certain inclination angle, and a collecting pipe 28 is arranged at one end of the bottom of the inner wall of the exhaust air chamber 12 away from the connecting pipe 19, part of the unevaporated distilled water drips onto the inner wall of the exhaust air chamber 12 along the heat conduction pipe 14 and flows into the collecting pipe 28 along the inner wall of the exhaust air chamber 12. Thus, the distilled water flows into the liquid storage chamber 17 along the collecting pipe 28, further solving the problem that in the traditional energy-saving ventilation device for underground buildings, when the air in the underground building is extracted by using the thermosiphon phenomenon, it is easily affected by the outer wall environment, resulting in the temperature rise in the ventilation pipe 3, the smaller temperature difference between the exhaust air chamber 12 and the ventilation pipe 3, and thus affecting the ventilation efficiency. By increasing the temperature difference between the exhaust air chamber 12 and the ventilation pipe 3, the thermosiphon phenomenon becomes obvious, and effectively increases the air flow rate in the ventilation pipe 3 and improves the air extraction efficiency.

[0040] A flow dividing bin 29 is installed in the middle of the ventilation pipe 3, and a groove 30 is formed in the bottom of the inner wall of the flow dividing bin 29. One side of the outer wall of the flow dividing bin 29 is fixedly connected with a waste liquid pipe 31, and a plugging block 32 is threadedly connected to the inner wall of the waste liquid pipe 31.

[0041] During operation, by arranging the flow dividing bin 29 in the middle of the ventilation pipe 3, when the outside temperature is relatively high, the air in the ventilation pipe 3 is likely to heat up during the process of flowing to the refrigeration bin 2. As a result, when the heated air contacts the heat sink 20, condensed water will be left on the surface of the heat sink 20. When the condensed water drips from the surface of the heat sink 20, it flows into the flow dividing bin 29 along the ventilation pipe 3. The groove 30 provided at the bottom of the inner wall of the flow dividing bin 29 is used to collect the condensed water, avoiding the remaining water stains inside the pipeline from generating peculiar smells. When it is necessary to clean the condensed water stored in the flow dividing bin 29, by arranging the waste liquid pipe 31 on one side of the outer wall of the flow dividing bin 29, the plugging block 32 provided on the inner wall of the waste liquid pipe 31 is removed, and the condensed water is discharged along the waste liquid pipe 31.

[0042] The working principle of the energy-saving ventilation device for the underground building will be specifically described below.

[0043] As Figures 1 - 10As shown in the figure, the air inlet housing 4 is installed on the top of the underground building, and connecting plates 11 are arranged at both ends of the inner wall of the air inlet housing 4. Support bases 10 are arranged on the outer walls of the connecting plates 11, and a shunt air inlet plate 8 is arranged at the bottom of the support bases 10. By pulling the handles 9 arranged at both ends of the bottom of the shunt air inlet plate 8, the filter bin 6 arranged at the top of the shunt air inlet plate 8 is disengaged from the air inlet pipe 5 arranged at the top of the inner wall of the air inlet housing 4. At this time, pushing the handle 9 forward causes the shunt air inlet plate 8 and the filter bin 6 to offset with the connecting plate 11 as the center. And a damping device is arranged in the connecting plate 11, so that the shunt air inlet plate 8 and the filter bin 6 remain inclined. At this time, a plurality of filter plates 7 are inserted into the filter bin 6, and the handle 9 is pulled to reset the shunt air inlet plate 8 and the filter bin 6. A ventilation pipe 3 is arranged at the top of the air inlet housing 4, and the ventilation pipe 3 extends to the roof. A ventilation main body 1 is installed on the roof, and one end of the ventilation pipe 3 is installed in the refrigeration bin 2 arranged at one end of the bottom of the inner wall of the ventilation main body 1. An exhaust bin 12 is arranged at the top of the ventilation main body 1, and a heat conduction pipe 14 is arranged on one side of the inner wall of the exhaust bin 12. By starting the semiconductor refrigeration plate 16 and using the liquid-cooled heat conduction bin 15 arranged on its heating surface, the heat is transferred into the heat conduction pipe 14, so that the temperature in the exhaust bin 12 continuously rises. At this time, a temperature difference is generated between the air in the exhaust bin 12 and the air in the ventilation pipe 3. Utilizing the thermosiphon phenomenon, the air in the ventilation pipe 3 continuously enters the exhaust bin 12. And in this process, a plurality of filter plates 7 arranged in the filter bin 6 are used to filter the air in the underground building, so that the air enters the exhaust bin 12 along the ventilation pipe 3 and is discharged through the exhaust pipe 13 arranged at the top of the exhaust bin 12, further solving the problem that in the process of using the traditional energy-saving ventilation device for underground buildings, due to the relatively complex structure, the daily maintenance is rather cumbersome.

[0044] The above has generally described the present invention in detail. However, based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the technical field. Therefore, the modifications or improvements made without departing from the spirit of the present invention are within the protection scope of the present invention.
