[0034] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0035] See also Figures 1 to 5, an active heat storage device for a solar greenhouse, comprising a water pool 1, a water pipe 2 and a water circulation system 3, wherein a heat preservation layer is arranged outside the water pool 1, and the water circulation system 3 is used to pump water in the water pool 1 into the water pipe 2, wherein the water circulation system 3 comprises a water pump, a pipe A and a pipe B, wherein one end of the pipe A is connected to the input end of the water pump, and the other end of the pipe A is connected to the inside of the water pool 1, one end of the pipe B is connected to the output end of the water pump, and the other end of the pipe B is connected to the inside of the water pipe 2, so that the water in the water pool 1 can be pumped into the water pipe 2, and the water pipe 2 is arranged horizontally and fixedly installed on the north wall of the greenhouse to maximize the use of solar radiation energy. The north wall receives solar radiation for a long time during the day, so installing the heat storage device on the north wall can maximize the absorption of solar radiation energy and store it, and a plurality of water leakage holes are opened at equal intervals at the bottom end of the water pipe 2 along its length direction, so that the water flows downward in the shape of a water curtain, thereby expanding the heat absorption and release area of ​​the water flow, and further comprising:

[0036] The guide body 4 is installed at the bottom of the water pipe 2. The guide body 4 is flat and hollow. The top of the guide body 4 is open and covers the multiple water leakage holes at the bottom of the water pipe 2. The water in the water pipe 2 flows into the guide body 4 through the water leakage holes. The bottom of the guide body 4 is connected with the inside of the pool 1 through a pipeline. The pool 1 is set at the bottom of the guide body 4. The side wall of the guide body 4 away from the north wall of the greenhouse is transparent to allow sunlight to irradiate into the guide body 4. The inner side surface of the guide body 4 close to the north wall of the greenhouse is coated with a black heat-absorbing material or covered with a black film.

[0037] A plurality of slow flow components 5 are evenly arranged inside the guide body 4. The slow flow components 5 include a sliding frame 51, a baffle plate 52 and a rotating shaft 53. One side of the sliding frame 51 is close to the inner side of the guide body 4 close to the north wall of the greenhouse. The top of the baffle plate 52 is rotatably mounted on the sliding frame 51 through the rotating shaft 53. The outer side wall of the rotating shaft 53 is fixedly connected to the baffle plate 52.

[0038] A driving mechanism 6, one side of which is respectively connected to the plurality of slow flow components 5, and the driving mechanism 6 is used to drive the spoiler 52 to rotate around the axis of the rotating shaft 53;

[0039] The regulating mechanism 7 has one side connected to the plurality of slow flow components 5 , and the regulating mechanism 7 can drive the plurality of slow flow components 5 to rise and fall synchronously relative to the flow guide body 4 .

[0040] See also Figure 2As shown, the water curtain heat storage and release system in the prior art relies on the wall structure of the solar greenhouse and uses water as a medium to store and release heat. During the day, water is circulated through the water curtain to absorb solar energy and store energy in the water. At night, water is circulated through the water curtain to release heat. The water curtain heat storage and release system can increase the nighttime temperature in the greenhouse by more than 5.4°C and the root zone temperature of the crop by more than 1.6°C. However, due to the change in the angle of sunlight and the obstruction of the roof behind the greenhouse, sometimes the water curtain can only be exposed to sunlight for a short time or in some areas. For areas with less sunlight and on cloudy days, the heat storage capacity of the water curtain is poor.

[0041] To this end, the present application continuously pumps water from the pool 1 into the water pipe 2 through the water circulation system 3, and the water in the water pipe 2 flows into the guide body 4 through multiple leaking holes to form a water curtain. The heat from sunlight absorbed by the black heat-absorbing material or the black film coated on the inner side surface of the guide body 4 close to the north wall of the greenhouse is absorbed and taken away by the water flow. When the sunlight exposure time is short, the baffle plate 52 is driven by the driving mechanism 6 to rotate around the rotating shaft 53 to tilt the baffle plate 52. At this time, the water flow will flow to the baffle plate 52. Under the blocking effect of the baffle plate 52, the flow rate of the water flow through the guide body 4 is delayed, so that the time for the water flow to absorb heat is prolonged, and the sunlight can only shine on the bottom of the guide body 4. When the water flow is in the lower position, the regulating mechanism 7 drives the plurality of slow-flow components 5 to synchronously move toward the bottom of the guide body 4, so that the plurality of baffles 52 are located at the bottom of the inner cavity of the guide body 4. At the same time, the driving mechanism 6 drives the baffles 52 to rotate and tilt around the rotating shaft 53 to delay the flow rate of the water flow at the bottom of the guide body 4, thereby prolonging the time for the water flow to absorb heat. In the area of ​​the guide body 4 not exposed to sunlight, the water flow is not hindered by the baffles 52, and the water flow quickly flows through the area not exposed to sunlight, thereby effectively adapting to the change of sunlight angle, and effectively solving the problem of low heat storage efficiency caused by the shading of the rear roof of the greenhouse, effectively improving the active heat storage efficiency of the device, and achieving better heat storage effect.

[0042] In one embodiment of the present invention, the body guide 4 is arranged vertically, and is fixedly installed on the north wall of the greenhouse through a fixing member. The body guide 4 is arranged vertically, which is suitable for heat storage in a greenhouse with a small internal space.

[0043] In one embodiment of the present invention, the guide body 4 is arranged in an inclined state, and the distance between the top end of the guide body 4 and the north wall of the greenhouse is smaller than the distance between the bottom end of the guide body 4 and the north wall of the greenhouse. The guide body 4 is fixedly installed on the north wall of the greenhouse by a fixing part. The guide body 4 is arranged in an inclined state to reduce the covering of the sunlight by the rear roof of the greenhouse.

[0044] In one embodiment of the present invention, the widths of the plurality of baffles 52 are different, and the width of the baffle 52 at the bottom is greater than the width of the baffle 52 at the top, so that the water flow can flow through all the baffles 52, which can further slow down the water flow rate and avoid the situation in which, when the water flow is large, the water flow flows through the top baffle 52 but not through the bottom baffle 52, resulting in a low effect on slowing down the water flow rate.

[0045] In one embodiment of the present invention, the outer surface of the baffle 52 is coated with a black heat-absorbing material or covered with a black film to improve the heat absorption effect of the device and avoid the situation where only the inner side surface of the guide body 4 close to the north wall of the greenhouse is coated with a black heat-absorbing material or covered with a black film, while the sunlight is blocked by the baffle 52 to reduce the heat absorption effect.

[0046] See also Figure 3 , Figure 5 and Figure 6 In one embodiment of the present invention, the driving mechanism 6 includes two groups of symmetrically arranged rotating driving components, the rotating driving components include an A sliding frame 61 and a plurality of swing arms 62, the plurality of swing arms 62 correspond to the plurality of slow flow components 5 one by one, one end of the plurality of swing arms 62 are respectively fixedly connected to the rotating shafts 53 adjacent thereto, and the other ends of the plurality of swing arms 62 are fixedly installed with A push rods 63, an A slide groove is provided on the A sliding frame 61, and the outer side walls of the plurality of A push rods 63 are respectively slidably connected with the inner wall of the A slide groove, and one side of the A sliding frame 61 is connected with an A telescopic driving member 64 for driving the A sliding frame 61 to move in a direction perpendicular to the inner side surface of the guide body 4 close to the north wall of the greenhouse, and the A telescopic driving member 64 is provided with two groups, and the A telescopic driving member 64 is a telescopic cylinder or a hydraulic cylinder, the moving end of the A telescopic driving member 64 penetrates the guide body 4 and is fixedly connected to the A sliding frame 61, and the fixed end of the A telescopic driving member 64 is fixedly installed on the outside of the guide body 4;

[0047] When the angle of the spoiler 52 needs to be adjusted, the A sliding frame 61 is driven to move by controlling the extension and retraction of the moving end of the A telescopic driving member 64. The inner wall of the A slide groove on the A sliding frame 61 pushes the A push rod 63. The A push rod 63 drives the spoiler 52 to rotate around the axis of the rotating shaft 53 through the swing arm 62 and the rotating shaft 53. Therefore, the inclination angle of the spoilers 52 in multiple slow flow components 5 can be adjusted synchronously, thereby adjusting the flow rate of the water flow.

[0048] See also Figure 3 , Figure 4 , Figures 7 to 10In one embodiment of the present invention, the adjustment mechanism 7 includes two groups of symmetrically arranged adjustment components, the adjustment components include a mobile driving component, a limit frame 71 and a plurality of sliders 72, the limit frame 71 is fixedly mounted on the inner wall of the guide body 4, the outer side surfaces of the plurality of sliders 72 are respectively slidably connected to the inner wall of the limit frame 71, the plurality of sliders 72 correspond to the plurality of sliding frames 51 one by one, one side of the plurality of sliders 72 is respectively fixedly connected to the adjacent sliding frames 51, the two end side surfaces of the sliding frames 51 are respectively slidably connected to the inner wall of the guide body 4, the other sides of the plurality of sliders 72 are respectively connected to the mobile driving components, and the mobile driving components are used to drive the plurality of sliders 72 to move synchronously along the height direction of the limit frame 71;

[0049] When the sunlight can only reach the bottom of the guide body 4, the multiple sliders 72 are driven by the mobile driving assembly to synchronously move downward along the height direction of the limit frame 71, and the sliders 72 drive the spoiler 52 to move synchronously through the sliding frame 51 and the rotating shaft 53. At the same time, the A push rod 63 in the driving mechanism 6 slides along the inner wall of the A slide groove on the A slide frame 61, so as not to affect the driving mechanism 6 to adjust the inclination angle of the spoiler 52;

[0050] In one embodiment of the present invention, the mobile driving assembly includes a B sliding frame 76 and a plurality of V-shaped rods, the plurality of V-shaped rods are arranged at equal intervals along the height direction of the limit frame 71, the V-shaped rods are composed of an A connecting rod 73 located at the top and a B connecting rod 74 located at the bottom, the end of the A connecting rod 73 is hinged to the end of the B connecting rod 74, the two ends of the plurality of V-shaped rods except the V-shaped rod at the bottom are respectively hinged to two adjacent sliders 72, the top end of the V-shaped rod at the bottom is hinged to the slider 72 at the bottom, the bottom end of the V-shaped rod at the bottom is hinged to the limit frame 71, and the sides of the plurality of B connecting rods 74 are fixedly installed with B push rods. Rod 75, B sliding frame 76 is provided with B sliding groove, and the outer side walls of multiple B push rods 75 are respectively slidably connected with the B sliding groove, and one side of the B sliding frame 76 is connected with a B telescopic driving member 77 that drives the B sliding frame 76 to move along the direction perpendicular to the inner side surface of the guide body 4 close to the north wall of the greenhouse, and the B telescopic driving member 77 is a telescopic cylinder or a hydraulic cylinder, and the moving end of the B telescopic driving member 77 passes through the side wall of the guide body 4 and is fixedly connected to the B sliding frame 76, and the fixed end of the B telescopic driving member 77 is fixedly installed on the outside of the guide body 4, and the upper and lower ends of the B sliding frame 76 are slidably connected with guide rods, and one end of the guide rod is fixedly connected to the limit frame 71;

[0051] When the moving end of the B telescopic driving member 77 is extended and retracted, the B sliding frame 76 is driven to move, and the inner wall of the B sliding groove on the B sliding frame 76 pushes the B push rod 75, and the B push rod 75 drives the B connecting rod 74 in the V-shaped rod to rotate. Since the B connecting rod 74 on the V-shaped rod at the bottom is hinged to the limit frame 71, when the B connecting rod 74 on the V-shaped rod at the bottom rotates, the slider 72 at the bottom is driven to move through the A connecting rod 73. When the slider 72 moves, it synchronously drives the B connecting rod 74 connected to it to rotate, and so on, multiple V-shaped The rods are folded or unfolded synchronously to drive the multiple B sliders 72 to move synchronously, so that the positions of the multiple slow-flow components 5 can be adjusted to adapt to the length of sunshine, so that the multiple slow-flow components 5 are evenly distributed inside the guide body 4, delaying the flow rate of water flowing through the guide body 4 while making the water absorb heat more evenly.

The temperature inside the guide body 4 is monitored by the temperature sensor, and multiple temperature sensors can be provided. The multiple temperature sensors respectively monitor the temperature at different heights inside the guide body 4, so that under the influence of the sunlight angle and the cover of the roof after the temperature is changed, only the bottom position of the guide body 4 can be exposed to sunlight, and the temperature sensor is used to sense it in time, so as to control the adjustment mechanism 7 and the driving mechanism 6 to control the position and rotation angle of the baffle 52.
