[0050] The installation of the power storage plate 34 can supply power to each sensor, pump body and power element in the whole seedling protection support device, reduce the engineering quantity and risk coefficient of external pull wires, better adapt to the actual application place of municipal gardens with strong illumination.

[0051] The embedded arc-shaped groove 5 is embedded in the fan-shaped clamping block 4, the arc-shaped rod 6 slides along the embedded arc-shaped groove 5, the arc-shaped cylinder groove 8 is embedded in the arc-shaped rod 6, the embedded spring 7 is embedded between the arc-shaped rod 6 and the arc-shaped cylinder groove 8, the pressure sensor 9 is attached to the inner side surface of each group of fan-shaped clamping blocks 4, the pressure sensor 9 is wrapped around the outer end of the seedling, and the pressure sensor 9 transmits the wrapping force of the fan-shaped clamping block 4 and the seedling wrapping.

[0052] The slot 11 is embedded in the inner surface of the left and right ends of the lower embedded groove 10, the number of the slot 11 is at least one group, the number of each group of slot 11 is set to one on the left and right, the support rod 3 is set to several groups, the two ends of each group of support rod 3 are fixedly connected by the linkage rod 12, and the two ends of the linkage rod 12 are embedded in the corresponding slot 11 and slide.

[0053] The function of the support rod 3 is to facilitate the positioning and support of the fan-shaped clamping block 4 at the upper end, and to support the whole seedling protection.

[0054] The inner end of the lower embedded groove 10 is fixedly connected with the sliding rod 13, the tail end of the sliding rod 13 slides along the linkage cylinder 14, the linkage cylinder 14 is embedded in the inner surface of the upper end of the support rod 3, the tail end of the sliding rod 13 is fixedly connected with one end of the linkage spring 32, and the other end of the linkage spring 32 is sequentially movably wound in the two groups of positioning rings 31.

[0055] The two groups of positioning rings 31 are provided with pressure sensing elements, which are used to sense the elastic force of the linkage spring 32.

[0056] The pressure sensor 9 located in the fan-shaped clamp block 4 is attached to the surface of the seedling in the initial state, and as the seedling grows, the embedded arc-shaped groove 5, the arc-shaped rod 6, the embedded spring 7 and the arc-shaped cylinder groove 8 in the fan-shaped clamp block 4 interact to expand the fan-shaped clamp block 4 outward. In the expansion process, the linkage cylinder 14 at the lower end of each fan-shaped clamp block 4 and the sliding rod 13 slide relative to each other, extruding the linkage spring 32 at the tail end of the sliding rod 13. The linkage spring 32 shrinks between the linkage cylinder 14 and the rotating cylinder 30. In this shrinking process, the contact pressure between the fan-shaped clamp block 4 and the surface of the seedling increases, affecting the growth of weak and small seedlings. At this time, the two pressure sensing elements wrapped at the tail end of the linkage spring 32 sense the increase in pressure and transmit a signal to the linkage motor 33. The linkage motor 33 drives the rotating cylinder 30 to rotate, pushing the tail end of the linkage spring 32 into the interior of the rotating cylinder 30. As a result, the spring force contraction of the linkage spring 32 decreases at an equal distance, and the length of the spring under stress decreases until the seedling grows to the limit of the support device. After removal, the linkage spring 32 is returned to the initial state by the linkage motor 33, and the cycle is repeated.

[0057] As shown in Figures 6-7 and Figures 10-11 , as a preferred embodiment, on the basis of the above-mentioned mode, further comprising: an embedded groove 15 and a buoyancy cylinder group 16 located at the side end of the support rod 3, a guide hole 18 is provided between the embedded groove 15 and the buoyancy cylinder group 16, a cover plate 19 is provided at the top end of the buoyancy cylinder group 16, and the buoyancy cylinder group 16 is provided in several layers.

[0058] A float 17 is installed at the upper end of each layer of the buoyancy cylinder group 16, and a guide plate 20 is fixed at the bottom of the lowermost layer of the buoyancy cylinder group 16, which floats up and down in the water storage cavity 21.

[0059] When the water level rises, the float 17 at the outer end of each layer of the buoyancy cylinder group 16 moves upward under the action of the rising water level along the guide hole 18 and the embedded groove 15, and the outer edge height of the cover plate 19 at the top end is less than the inner edge height, which can effectively block part of the rainwater from entering the inner end of the buoyancy cylinder group 16.

[0060] As shown in Figures 12-16 , as a preferred embodiment, on the basis of the above-mentioned mode, further, the bottom end of the water storage cavity 21 is sequentially arranged with an outer micro water pump 22 and an inner micro water pump 23, the outer micro water pump 22 is connected to the outer side of the support 1 and the water storage cavity 21, the inner micro water pump 23 is connected to the water storage cavity 21 and the support leg, an inner connecting pipeline 24 is provided between the inner micro water pump 23 and the support leg, and the outer end of the inner connecting pipeline 24 is connected with a plurality of water injection pipelines 25, and the upper end of each water injection pipeline 25 is connected with an extension pipeline 26.

[0061] The outer micro water pump 22 draws water from outside into the water storage cavity 21 when the water rises. At this time, the inner micro water pump 23 is closed. A water level sensor is arranged at the top end of the water storage cavity 21. When the guide plate 20 collides with the inner top end of the water storage cavity 21, the water level sensor is triggered. At this time, the water level in the water storage cavity 21 reaches the maximum value. The outer micro water pump 22 is powered off. At this time, the water storage cavity 21 is filled with water, which can increase the weight of the support 1 and prevent the seedling from being washed away. Secondly, it can also store water for the roots. When it is dry, the roots can be watered in time by the inner micro water pump 23. Thirdly, the outer micro water pump 22 can also artificially store water. It only needs to connect the water pipe to the water inlet end of the outer micro water pump 22 to realize water storage in the water storage tank. Humidity sensors are arranged at the side ends of the support legs, which can sense the humidity of the roots in real time, so as to supplement water to the roots by the inner micro water pump 23.

[0062] The outer micro water pump 22 and the inner micro water pump 23 adopt existing small-flow circulating micro water pumps for aquariums. The length, width and height of each micro water pump are controlled within 10 cm, such as AEC-600 of Chuexing, BP-380 of Boyu and HP-600 of Risheng. However, according to the size of the seedling after growing up, different specifications of seedling protection support devices can be selected at the beginning of planting.

[0063] In practice, the outer micro water pump 22 can also inject nutrients required by the corresponding seedling into the water storage cavity 21. The injection time and interval are injected into the automatic system platform, and the inner micro water pump 23 is pushed to inject into the seedling roots at a specific time and time end.

[0064] The front and back sides of the extension pipeline 26 are respectively provided with end connecting ropes 27. The first and last ends of the end connecting ropes 27 are respectively fixed to the head end of the water injection pipeline 25 and the top end of the extension pipeline 26.

[0065] The end connecting ropes 27 (adopting a line body made of hot melting material, such as wax line in the prior art) are adapted to different depths of the support legs, so as to ensure that the end connecting ropes 27 of different depths of the support legs can be quickly melted or broken under corresponding thermal friction, so as to ensure that the extension pipeline 26 can be bent in the soil. The bending of the extension pipeline 26 in the soil has enough space (which is generated by the contact between the support leg and the soil in the process of inserting the support leg into the soil, and the corresponding soil is extruded to form a space for the extension pipeline 26 to bend out).

[0066] Each main inner connecting pipe 24 is arranged with a plurality of water injection pipelines 25 in up and down directions. The water outlet ends of the water injection pipelines 25 are respectively provided with a group of extension pipelines 26. The thickness and melting resistance of the end connecting ropes 27 of the extension pipelines 26 at different depths of the support legs are different.

[0067] According to the actual use, the end connecting rope 27 is wax line (melting point at 40-90℃):

[0068]

[0069] By fixing the bending of the extension pipeline 26 in the soil, firstly, it can facilitate the uniform moisture of the roots of the seedling, secondly, it can mimic the roots of the branches, and ensure that the bottom of the seedling protection support device has good grip in the soil, facilitating the fixation of the seedling protection support device;

[0070] In this process, as long as the extension pipeline 26 can realize rotation to change the angle, in the initial state, the overall folding angle of the extension pipeline 26 is about 80 degrees, as long as the water outlet end of the extension pipeline 26 can be rotated downward, which can prevent the soil from blocking the water outlet end.

[0071] The inner end of the extension pipeline 26 is embedded with a spring member, and the outer end of the extension pipeline 26 is fixed with a plurality of arc-shaped sliding plates 29, the outer end of the arc-shaped sliding plate 29 is connected with an arc-shaped guide groove 28, and the arc-shaped guide groove 28 is embedded in the top end outer surface of the water injection pipeline 25.

[0072] The inner end of the extension pipeline 26 can quickly drive the extension pipeline 26 to bounce after the end connecting rope 27 breaks through the spring member;

[0073] The arc-shaped sliding plate 29 is fixedly connected with each layer of the outward folding position of the extension pipeline 26, which ensures that the extension pipeline 26 can quickly rotate along the arc-shaped guide groove 28 during the bouncing process, and ensures that the water outlet end of the extension pipeline 26 is downward or obliquely downward;

[0074] The water outlet end of the extension pipeline 26 has a filter screen to prevent mud and sand from entering, and the filter screen and the downward extension pipeline 26 can well prevent the water outlet end from being covered and buried by wet mud and sand.

[0075] All pressure sensors 9, humidity sensors and micro water pumps in the seedling protection support device are connected to the existing automatic garden irrigation system, which can realize the monitoring and management of the growth of all seedlings planted in the municipal garden and various data, and can also conveniently cope with different scenes such as flood disaster or drought weather.

[0076] The application is used:

[0077] (1) Device installation and initial state

[0078] Insert the support 1 with the legs 2 into the soil, select the appropriate size device according to the size of the seedling after adult; Install the strut 3 on the support 1, the two ends of each group of strut 3 are fixed by the linkage rod 12, the two ends of the linkage rod 12 are embedded in the corresponding slot 11 and slide; The fan-shaped clamp block 4 is movably connected to the upper end of the strut 3, so that the pressure sensor 9 located in the fan-shaped clamp block 4 is attached to the surface of the seedling in the initial state; The embedded slot 15 and the buoyancy cylinder group 16 are installed at the side end of the strut 3, the float 17 is installed at the upper end of each layer of the buoyancy cylinder group 16, the guide plate 20 is fixed at the bottom of the lowermost layer, and the guide plate 20 can float up and down in the water storage cavity 21; The outer micro water pump 22 and the inner micro water pump 23 are arranged in sequence at the bottom end of the water storage cavity 21, and the related pipelines are connected, such as the outer micro water pump 22 connected to the outside of the support 1 and the water storage cavity 21, and the inner micro water pump 23 connected to the water storage cavity 21 and the support leg through the inner connecting pipeline 24. The outer end of the inner connecting pipeline 24 is connected to a plurality of water injection pipelines 25, the upper end of each water injection pipeline 25 is connected to an extension pipeline 26, and end connecting ropes 27 are arranged on the front and rear sides of the extension pipeline 26. All the pressure sensors 9, humidity sensors and micro water pumps in the device are connected to the existing automatic garden irrigation system.

[0079] (2) Self-adaptive adjustment during the growth of seedlings:

[0080] With the thickening of the seedlings, the embedded arc-shaped slot 5, the arc-shaped rod 6, the embedded spring 7 and the arc-shaped cylinder slot 8 in the fan-shaped clamp block 4 interact, and the fan-shaped clamp block 4 expands outward. During this process, the linkage cylinder 14 at the lower end of each fan-shaped clamp block 4 and the sliding rod 13 slide relative to each other, extruding the linkage spring 32 at the tail end of the sliding rod 13. The linkage spring 32 is contracted between the linkage cylinder 14 and the rotating cylinder 30, and the contact pressure between the fan-shaped clamp block 4 and the surface of the seedling increases. When the two pressure sensing elements wrapped at the tail end of the linkage spring 32 sense that the pressure increases, a signal is transmitted to the linkage motor 33, which drives the rotating cylinder 30 to rotate, pushing the tail end of the linkage spring 32 into the interior of the rotating cylinder 30, so that the contraction amount of the elastic force of the linkage spring 32 decreases, and the length of the spring under stress decreases, until the seedling thickens to the limit value of the supporting device. After the device is removed, the linkage spring 32 is returned to the initial state by the linkage motor 33, and can be reused.

[0081] (3) Response to different weather conditions:

[0082] Rising water condition: when the water rises, the outer micro water pump 22 draws water from outside into the water storage cavity 21, and the inner micro water pump 23 is closed at this time. The floating ring 17 at the outer end of each layer of the buoyancy cylinder group 16 moves upward along the guide hole 18 and the embedded slot 15 under the action of the rising water height, and the top cover plate 19 can block part of the rainwater from entering the inner end of the buoyancy cylinder group 16. When the guide plate 20 collides with the inner top of the water storage cavity 21, the water level sensor is triggered, and the outer micro water pump 22 is powered off. At this time, the water storage cavity 21 is filled with water, which can increase the weight of the support 1 and prevent the seedlings from being washed away.

[0083] Drought condition: the humidity sensor at the side end of the support foot senses the root humidity in real time. When drought is detected, the inner micro water pump 23 is started, and the soil around the roots is watered through the water injection pipeline 25 and the extension pipeline 26. Artificially, the outer micro water pump 22 can also store water. Connect the water pipe to the water inlet end of the outer micro water pump 22 to store water in the water storage tank.

Although the present application has been described in detail with reference to the above embodiments, the present application is not limited to the above specific embodiments. Therefore, any modification or equivalent replacement of the present application; and all technical solutions and improvements without departing from the spirit and scope of the application are encompassed in the scope of the claims of the present application.
