DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-5 , the present invention provides a technical solution:

[0027] Embodiment 1:

[0028] Autonomous mobile wind and rain shelter for crops, including:

[0029] A plurality of canopy frames 1, wherein the plurality of canopy frames 1 are in an arch shape, and are composed of columns 2 on both sides and a top arch 3 integrally welded and fixed on the upper part. Track wheels 4 are installed at the bottom of the columns 2 on both sides. A scissor-type telescopic frame 5 is also movably installed on the side of the plurality of canopy frames 1. The scissor-type telescopic frame 5 is combined with the plurality of canopy frames 1 to form a main frame of the rain shelter. The plurality of canopy frames 1 are linearly translated and slid under the traction of the traction mechanism. During the translation and sliding process, the adjacent canopy frames 1 are always kept equidistant under the action of the scissor-type telescopic frame 5. The traction mechanism works under the control of wind force, rainfall sensors and manual control;

[0030] The inner tarpaulin cover is arranged on the outside of the canopy frame 1 and is stretched or wrinkled and stored correspondingly during the equidistant extension and retraction process of the canopy frame 1;

[0031] A pair of sliding rail seats 6 are laid in parallel on the telescopic path of the canopy frame 1, and a first rail 7 for accommodating the rail wheel 4 of the column 2 is installed on the sliding rail seat 6;

[0032] An experimental field 8, the experimental field 8 is opened between the sliding track seats 6 on both sides; and,

[0033] Functional cable tarpaulins on both sides are respectively rolled up and arranged in the outer tarpaulin cabins 9 on both sides. The outer tarpaulin cabins 9 are fixedly installed on the ground and parallel to the sliding track seat 6. The functional cable tarpaulin includes a cable rope 10, an outer tarpaulin 11 and a tarpaulin connecting guide strip 12. The tarpaulin connecting guide strip 12 is fixedly connected between the cable rope 10 and the outer tarpaulin 11. The cable rope 10 is connected above the column 2 of the canopy frame 1 through a winding motor 13. The outer tarpaulin 11 is rolled up on the winding roller 14 arranged in the outer tarpaulin cabin 9. The outer tarpaulin 11 is pulled up or down by the winding and unwinding operation of the winding motor 13 and the winding roller 14. The cable rope 10 is kept in a taut state to tighten the main frame of the rain shelter. When the wind force or rainfall reaches the set threshold, the winding motor 13 rotates the cable rope to tighten the main frame of the rain shelter. The rope 10 is reeled in, and the pull rope 10 pulls the tarpaulin connecting guide bar 12 upward to drive the outer tarpaulin 11 to unwind outward, thereby performing sloped shielding on both sides of the main frame of the rain shelter. Benefiting from the slope structure formed by the outer tarpaulin 11, the wind resistance of the rain shelter can be reduced and the wind force can be better guided. At the same time, the setting of the sloped outer tarpaulin 11 can also guide and collect rainwater. A rainwater diversion and collection trough 15 is opened in the outer tarpaulin cabin 9, and water collecting tanks are arranged at both ends of the outer tarpaulin cabin 9. The rainwater entering the rainwater diversion and collection trough 15 flows into the water collecting tank from both ends of the outer tarpaulin cabin 9 to be collected. Tarpaulins or rolling shutters can be used at both ends of the awning as the door structure for entering and exiting the awning. On the one hand, it isolates the harsh external environment to prevent rain and wind leakage in the shed, and on the other hand, it provides an exit channel for experimenters to enter and exit the awning.

[0034] In this embodiment, the canopy frame 1 serves as the main structure of the canopy. A plurality of canopy frames 1 are linearly arranged to form a main frame. A scissor-type telescopic frame 5 is installed on the sides of the plurality of canopy frames 1 so that the canopy frames 1 can maintain an equidistant arrangement state during the telescopic process. The plurality of canopy frames 1 are contracted to achieve the contraction and expansion of the frame. The movement of the canopy frame 1 is performed on the sliding track seat 6. The track wheel 4 of the column 2 cooperates with the first track 7 to facilitate the telescopic movement. The movement process is performed during the working of the traction mechanism. The traction mechanism works under the control of wind and rain sensors and manual control. Specifically, the windproof and rain shelter in this embodiment is controlled by the main control MCU installed in the control center. The main control MCU is also electrically connected to the wind sensor and the rain sensor. When one of the wind sensor and the rain sensor reaches the set threshold, the main control MCU sends a work instruction to the traction mechanism to control it to drive the canopy frame 1 to perform telescopic movement. In addition, the movement of the traction mechanism can also be controlled by manual instructions. Since this control mechanism is more common in the prior art, it will not be repeated here. As described above, an inner tarpaulin is provided on the outer side of the canopy frame 1, and its installation method is consistent with the tarpaulin installation method in the prior art, and can be installed by magic self-adhesion or rivets to form a first layer of protective tarpaulin. The tarpaulin layer is adaptively unfolded or wrinkled during the telescopic movement of the canopy frame 1. The purpose of the above-mentioned device is to cope with the strong wind weather in South China, to match the crop cultivation pool, to protect the test crops planted in the test field from typhoons and heavy rainfall, and to ensure the normal internal water control test. On the basis of this existing structure, the present embodiment also adds functional The active cable tarpaulin is composed of a cable rope 10, an outer tarpaulin 11 and a tarpaulin connecting guide bar 12. The cable rope 10 is not only used to pull the outer tarpaulin 11, but also to pull the canopy frame 1, so as to ensure the structural strength of the canopy body. In addition, when the wind speed or rainfall reaches the set threshold, the cable rope 10 is reeled under the traction of the reeling motor 13. During this process, the outer tarpaulin 11 is synchronously unwound from the reeling roller 14, wherein the unwinding roller 14 is also provided with a motor to drive its movement, so that the outer tarpaulin 11 can be unwound to protect both sides of the canopy body, refer to the attached manual Figure 3After the outer tarpaulin 11 is unrolled, a sloped surface is formed. Compared with the side surface of the inner tarpaulin which is perpendicular to the bottom surface, the setting of its sloped surface structure can further reduce the wind resistance, thereby reducing the damage to the canopy body caused by wind in extremely bad weather. At the same time, the sloped surface formed by the outer tarpaulin 11 can also guide rainwater to fall on rainy days, and cooperate with the rainwater diversion and collection groove 15 set at the bottom of the outer tarpaulin cabin 9 to guide rainwater into the water collecting tank at both ends of the outer tarpaulin cabin 9. In summary, the setting of the functional cable tarpaulin enables the canopy to have multiple functions. The setting of the cable rope 10 and the outer tarpaulin 11 structure further improves the structural rigidity of the canopy frame 1, and at the same time, it also plays a role in reducing the wind resistance of the canopy body, and the setting of the sloped surface can better collect rainwater, thereby improving the utilization rate of water resources.

[0035] Embodiment 2:

[0036] Sliding rods 17 are installed on the outer sides of the columns 2 through diagonal braces 16. The sliding rods 17 are also installed with track wheels 4 on the side close to the sliding track seat 6. The sliding track seat 6 is installed with a second track 18, which is used to accommodate the track wheels 4 on the sliding rods 17.

[0037] A sliding groove 19 is provided in the tarpaulin connecting guide bar 12, and magnetic connecting sliders 20 are installed in the sliding groove 19 for translational sliding. The number of magnetic connecting sliders 20 is the same as that of the canopy frame 1 and corresponds to each other one by one. The magnetic connecting sliders 20 are magnetically matched with the magnetic adsorption blocks 21 installed at the ends of the sliding rods 17. During the translational sliding process of the canopy frame 1, the sliding rods 17 and the magnetic connecting sliders 20 perform translational movements synchronously, so that the plurality of cable ropes 10 remain in an equidistant and parallel state.

[0038] The traction mechanism for pulling the canopy frame 1 for linear translation and sliding includes a pair of winding and unwinding motors 22 arranged on both sides of the movement direction of the canopy frame 1. The pair of winding and unwinding motors 22 are connected to the canopy frame 1 at the telescopic front end through a traction rope 23. The winding and unwinding operation is performed by the winding and unwinding motors 22 on both sides to perform equidistant telescoping of the canopy frame 1.

[0039] In this embodiment, a connection method between the tension rope 10 and the tarpaulin connecting guide bar 12 is further disclosed, and a sliding connection method is adopted between the two. Since the awning frame 1 needs to perform telescopic movement, and the outer tarpaulin 11 is arranged in a retracted manner in the outer tarpaulin cabin 9 and cannot be retracted, for this reason, the sliding rod 17 is fixedly connected to the awning frame 1 through the diagonal support rod 16, and the sliding rod 17 can perform telescopic movement synchronously with the awning frame 1. During the telescopic movement, the sliding rod 17 attracts the magnetic connection slider 20 through the magnetic adsorption block 21 installed at the end, so that the magnetic connection slider 20 performs telescopic movement synchronously in the sliding groove 19 of the tarpaulin connecting guide bar 12, thereby keeping a plurality of tension ropes 10 in an equidistant and parallel state, wherein the tarpaulin connecting guide bar 12 is a long strip rod structure that cannot be retracted. When the outer tarpaulin 11 needs to be unwound, the tarpaulin connecting guide bar 12 can be pulled up by rewinding the tension rope 10, thereby realizing the unwinding of the outer tarpaulin 11.

[0040] Embodiment three:

[0041] The canopy frame 1 is in the canopy storage room 24 in the retracted state. In this embodiment, the canopy frame 1 in the retracted state is protected by the canopy storage room 24.

[0042] Embodiment 4:

[0043] The outer tarpaulin cabin 9 is located above the outer tarpaulin 11 and is further provided with a water inlet 25 , through which rainwater falling from the outer tarpaulin 11 enters the rainwater diversion collection groove 15 at the bottom of the outer tarpaulin cabin 9 .

[0044] In order to better guide rainwater into the rainwater diversion collection groove 15, a water inlet hole 25 is also opened on the outer tarpaulin cabin 9. After falling, rainwater enters the rainwater diversion collection groove 15 at the bottom of the outer tarpaulin cabin 9 through the water inlet hole 25, and finally enters the water collection tank by moving to both sides.

[0045] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
