DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0031] The purpose of the present invention is to provide a temperature regulating system for artificial wetlands suitable for cold regions, broaden the application scope of artificial wetlands, and provide technical support for the operation of artificial wetlands in cold regions.

[0032] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.

[0033] Reference Figure 1 to Figure 6 , this embodiment provides an artificial wetland temperature regulation system suitable for cold areas (hereinafter referred to as the artificial wetland temperature regulation system), including an insulation shed. The insulation shed includes a shed wall 2 and a shed roof 1. The shed roof 1 includes a support rod 11, an insulation top film 12 and an airbag layer 13. The support rod 11 is fixed to the top of the shed wall 2. The insulation top film 12 is located on the upper side of the support rod 11, and the airbag layer 13 is located on the lower side of the support rod 11. An air layer 14 is formed between the insulation top film 12 and the airbag layer 13. The airbag layer 13 includes a plurality of sealed airbags 132. A through hole 131 is provided on the airbag layer 13, and the through hole 131 connects the upper and lower sides of the airbag layer 13. The insulation top film 12 is supported by the support rod 11, the edge of the airbag layer 13 is fixed on the shed wall 2, and the middle part of the airbag layer 13 can be optionally suspended on the support rod 11 by a suspension rope to avoid sagging.

[0034] The working principle of the artificial wetland temperature regulation system in this embodiment is as follows:

[0035] By providing an air layer 14 between the thermal insulation top film 12 and the air bag layer 13, the influence of the external cold air on the artificial wetland 6 below the air bag layer 13 can be reduced, and the artificial wetland 6 can be prevented from freezing. In addition, after the water and filler inside the artificial wetland 6 are heated, the hot air passes upward through the through holes 131 on the air bag layer 13 and enters the air layer 14, condenses and releases heat in the air layer 14, maintains the temperature of the air layer 14, and thus improves the thermal insulation effect of the artificial wetland 6 below. During the day, sunlight passes through the thermal insulation top film 12 and the air bag layer 13 to reach the artificial wetland 6, ensuring sufficient photosynthesis of wetland plants and maintaining the temperature of the artificial wetland 6. At night, due to the presence of the air layer 14, the artificial wetland 6 dissipates heat slowly, ensuring that it is within the required temperature range.

[0036] As a possible example, in this embodiment, the shed wall includes two telescopic walls and three heat-insulating side films 23. The telescopic wall includes a telescopic frame 21 and a fixed frame 22. The telescopic frame 21 has a fixed end and a sliding end, and the fixed end is fixedly connected to the fixed frame 22. Support rods are fixed to the tops of the telescopic frame 21 and the fixed frame 22. A heat-insulating side film 23 is provided on each side of the two telescopic walls facing away from the artificial wetland 6, and the two ends of the other heat-insulating side film 23 are respectively connected to the two fixed frames 22. The tops of the telescopic frame 21 and the fixed frame 22 are connected to the support rod 11 and the air bag layer 13, and the solar collector 54 is fixed on the support rod 11 connected to the fixed frame 22.

[0037] Since both telescopic walls include a telescopic frame 21, the length of the two telescopic walls can be adjusted, thereby driving the roof 1 and one of the connecting walls to move, thereby realizing the unfolding and folding of the insulation shed. Compared with ordinary insulation sheds, the insulation shed in the present application is more convenient to unfold and fold due to its structural characteristics, so that it is convenient to choose whether to erect the insulation shed according to weather conditions, thereby improving operational flexibility. In order to improve the stability of the fixed frame 22, the lower end of the fixed frame 22 can be buried in the foundation.

[0038] As a possible example, in this embodiment, the telescopic wall further includes a pulley 24 and a track 25. The pulley 24 is rotatably mounted on the bottom of the telescopic frame 21. The track 25 is located below the pulley 24 and is used to guide the pulley 24. The pulley 24 slides along the track 25, and the sliding process is relatively smooth, which can prevent the uneven soil from causing obstruction to the lower end of the telescopic frame 21, so as to improve the smoothness of the expansion and folding process of the thermal insulation shed.

[0039] As a possible example, in this embodiment, the telescopic frame 21 is an electric telescopic frame 21, including a drive motor 26, and the drive motor 26 is used to drive the telescopic action of the electric telescopic wall, and its principle is similar to that of an electric telescopic door.

[0040] The artificial wetland temperature regulation system also includes a control system. The control system includes a temperature sensor 31, a rainfall sensor 32 and a control unit 3. The temperature sensor 31 and the rainfall sensor 32 are both installed on the outside of the insulation shed and are electrically connected to the control unit 3 respectively. The control unit 3 is electrically connected to the drive motor 26 and is used to control the telescopic action of the telescopic wall according to the feedback of the external temperature and rainfall. The control unit 3 determines the correspondence between the measured values ​​of the temperature sensor 31 and the rainfall sensor 32 and the shape of the insulation shed by presetting the control program, and then the intelligent unfolding and folding control of the insulation shed can be realized without manual operation, thereby saving labor costs and improving the response speed to environmental changes.

[0041] As a possible example, in this embodiment, the control system further includes a micro camera 33, which is electrically connected to the control unit 3. The micro camera 33 is installed inside the insulation shed for real-time monitoring of the artificial wetland 6. The control unit 3 can adjust the monitoring angle, monitoring viewing distance and other parameters of the micro camera 33, and can upload the monitoring video to the cloud in real time.

[0042] As a possible example, in this embodiment, the artificial wetland temperature regulation system suitable for cold regions also includes a clean energy collection system 4 and an energy conversion system 41. The clean energy collection system 4 is used to collect clean energy in the environment, and the energy conversion system 41 is used to convert the clean energy collected by the clean energy collection system 4 into electrical energy.

[0043] The clean energy collection system 4 can be a solar panel for collecting solar energy, or a wind turbine for collecting wind energy. The location of the clean energy collection system 4 can be flexibly selected, for example, arranged on the upper side of the thermal insulation top film 12 and supported by the support rods 11.

[0044] Taking solar panels as an example, the energy conversion system 41 matched with the solar panels includes a solar controller 411, a battery pack 412 and a solar inverter 413. The solar panel is electrically connected to the solar controller 411, the solar controller 411 is electrically connected to the battery pack 412, the battery pack 412 is electrically connected to the solar inverter 413, and the solar inverter 413 is used to supply power to the power system 42. The energy conversion system 41 can be fixed on the fixed frame 22, or it can be fixed on the support rod 11 connected to the fixed frame 22. When the telescopic frame 21 is telescopically deformed, the position of the fixed frame 22 remains unchanged, so the position of the solar panel and the energy conversion system 41 does not change.

[0045] As a possible example, in this embodiment, the artificial wetland temperature regulation system suitable for cold regions also includes an electricity system 42 , where the electricity system 42 is used to heat the artificial wetland, and the energy conversion system 41 supplies power to the electricity system 42 .

[0046] The electric energy provided by the energy conversion system 41 can supply power to various power systems 42, thereby expanding the utilization of clean energy. According to different types of power systems 42, examples are given below, and the actual implementation is not limited thereto.

[0047] As a possible example, in this embodiment, the power system 42 includes an electric heating tube, which is inserted around the filler layer 63 of the artificial wetland 6, and the energy conversion system 41 supplies power to the electric heating tube. The electric heating tube acts as a thermal resistor and generates heat using the electric energy provided by the battery pack 412, thereby increasing the temperature of the artificial wetland 6.

[0048] As a possible example, in this embodiment, the power system 42 includes a heat pump unit and a fan coil unit. The heat pump unit is connected to the fan coil unit to form a water cycle between the heat pump unit and the fan coil unit. The fan coil unit is installed in the insulation shed to heat the insulation shed. The energy conversion system 41 supplies power to the heat pump unit so that the heat pump unit can continue to work. The heat pump unit uses geothermal energy to heat the circulating water, which flows to the fan coil unit in the insulation shed, dissipates heat at the fan coil unit, and then flows back to the heat pump unit.

[0049] As a possible example, in this embodiment, the power system 42 can be a solar thermal collection system 5, which includes a solar thermal collector 54, a circulation pump 51, a water inlet pipe 52 and a water outlet pipe 53. The solar thermal collector 54 is fixed on the support rod 11 connected to the fixed frame 22. When the telescopic frame 21 performs a telescopic action, the position and shape of the fixed frame 22 remain unchanged, and the position of the support rod 11 connected to the fixed frame 22 remains unchanged, thereby maintaining the stability of the solar thermal collector 54. The two ends of the water inlet pipe 52 are respectively connected to the water inlet end of the solar thermal collector 54 and the water collection channel 61 of the artificial wetland 6, which is used to send cold water into the solar thermal collector 54. The two ends of the water outlet pipe 53 are respectively connected to the water outlet end of the solar thermal collector 54 and the water distribution channel 62 of the artificial wetland 6, which is used to send hot water into the water distribution channel 62 of the artificial wetland 6. A circulation pump 51 is installed on the water inlet pipe 52. The energy conversion system 41 supplies power to the circulation pump 51. The solar collector 54 stores clean energy in circulating water (different from the circulating water in the heat pump unit), and then the circulating water transports the heat to the artificial wetland 6 through water circulation, thereby improving the heating efficiency of the artificial wetland 6.

[0050] It is understandable that when the telescopic frame 21 is telescopic, the telescopic frame 21 should not interfere with the water inlet pipe 52 and the water outlet pipe 53 to avoid affecting the movement of the telescopic frame 21. Therefore, the vertical sections of the water inlet pipe 52 and the water outlet pipe 53 should be arranged on the fixed frame 22, and the horizontal sections of the water inlet pipe 52 and the water outlet pipe 53 should be arranged on the inner side of the insulation shed.

[0051] As a possible example, in this embodiment, the airbag layer 13 includes a plurality of sealed airbags 132, and the plurality of sealed airbags 132 are distributed in a plurality of groups, and two adjacent sealed airbags 132 in the same group are connected by a connecting tube 133. The sealed airbags 132 are elliptical and filled with air. Since the plurality of sealed airbags 132 in the same group are connected to each other, the plurality of sealed airbags 132 in the same group are inflated and deflated at the same time. In addition, since the airbag layer 13 is not set as an integral airbag, but is decomposed into a plurality of sealed airbags 132, it is easy to fold, so as to avoid obstruction when the telescopic frame 21 is contracted.

[0052] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scope. In summary, the content of this specification should not be understood as limiting the present invention.
