Description

Technical Field

[0001] The utility model relates to the technical field of field test equipment, and more specifically, to a self-starting rain increasing and decreasing device. Background Art

[0002] In the existing rainfall experiments, the rain increasing and decreasing experiments are widely used. The rain increasing and decreasing experiment means setting a rain reducing area at one place in the sample plot and a rain increasing area at another place, and sending the rainwater intercepted by the rain reducing area to the rain increasing area to study the influence on the soil of the sample plot. The key to carrying out the field control experiment of rain increasing and decreasing is to design a reasonable rain shelter. At present, the rain shelters adopted by scholars mainly include two types: fixed rain shelters and movable track rain shelters.

[0003] The fixed rain shelter is mainly composed of a steel support, a rain intercepting groove and a rain collecting box. One end of the support is high and the other end is low. The rain intercepting groove is generally a V-shaped groove made of high-transparency organic glass or polycarbonate PC board and is uniformly fixed on the support according to the rain reducing ratio. The bottom end of the rain intercepting groove is generally connected to a rain collecting groove to collect rainwater into the rain collecting box, and the rainwater in the rain collecting box is irrigated to the rain increasing area through an artificial or water pump conveying system, or a drip irrigation pipe can be directly connected to the bottom end of the rain intercepting groove to directly irrigate the rainwater to the rain increasing area. The fixed rain shelter is the most widely used at present because of its simple structure, low cost and easy production. However, the fixed rain shelter has problems such as shading, wind blocking and hindering gas exchange, which are likely to affect the test results.

[0004] The movable track rain shelter installs a sliding track at the bottom of the support. When there is no rain, it is placed in the non-test area to reduce the environmental impacts of the rain shelter on the test area such as shading, wind blocking and hindering gas exchange. When it rains, the whole rain shelter can be manually pushed to move, or a motor and a rainfall automatic induction device can be installed to realize the automatic movement of the rain shelter for rain shielding when it rains. However, its cost is relatively high, and the operation and maintenance costs are relatively high. At the same time, the installation process of the track will damage the surface soil and surface vegetation, which has a certain environmental impact on the sample plot.

[0005] Therefore, how to provide a self-starting rain increasing and decreasing device with little impact on the sample plot environment, simple structure and low cost is an urgent problem to be solved by those skilled in the art. Content of the Utility Model

[0039] Please refer to Figures 1-5, an embodiment of the present utility model discloses a self - starting rain increasing and decreasing device, including: a rain gauge 1, a controller, a rain collection barrel 3, a rain reduction component 2 arranged in a rain reduction area 100, and a rain increasing mechanism 4 arranged in a rain increasing area 200; characterized in that the rain reduction component 2 includes:

[0040] A bracket 21, the rain reduction area 100 has two relatively arranged ends, and the bracket 21 is fixed to one end of the rain reduction area 100;

[0041] A rain shelter 22, one end of the rain shelter 22 is rotatably installed on the top of the bracket 21; the rain shelter 22 has a first position and a second position. The first position is that the rain shelter 22 flips outside the rain reduction area 100 and its end far from the bracket 21 supports on the ground outside the rain reduction area 100; the second position is that the rain shelter 22 flips above the rain reduction area 100, and the end of the rain shelter 22 far from the bracket 21 inclines downward and extends to the other relatively arranged end of the rain reduction area 100;

[0042] A rain collection box 23, the rain collection box 23 is correspondingly arranged on the side of the rain shelter 22 far from the bracket 21. A rainwater inlet is opened on the side of the rain collection box 23 close to the rain shelter 22 to receive the rainwater on the rain shelter 22, and a drain port 231 is opened at the bottom of the rain collection box 23;

[0043] A driving mechanism 24, the driving mechanism 24 is installed on the bracket 21 and its output end is connected to the rain shelter 22 to drive the rain shelter 22 to flip between the first position and the second position;

[0044] The rain gauge 1 is installed outside the rain reduction area 100. The rain collection barrel 3 is placed below the rain collection box 23 corresponding to the drain port 231. The rain increasing area 200 is arranged side by side on the side of the rain reduction area 100 far from the bracket 21. The input end of the rain increasing mechanism 4 is communicated with the rain collection barrel 3 to convey the rainwater in the rain collection barrel 3 to the rain increasing area 200, and the controller is electrically connected to the driving mechanism 24.

[0045] This device can realize the conversion of the rain shelter between the first position and the second position by driving the rain shelter 22 to flip around the bracket 21 by the driving mechanism 24. When there is no rain, the rain shelter 22 is in the first position to prevent the influence on the sample plot environment such as shading and wind blocking. When it is raining, the rain shelter 22 is in the second position to carry out rain reduction tests by shielding rain, and collect rainwater. The collected rainwater is conveyed to the rain increasing area 200 through the rain increasing mechanism 4 for rain increasing tests. This device has a simple structure, is easy to operate, and avoids the damage to the sample plot and the influence on the sample plot environment.

[0046] The rain gauge 1 can adopt a tipping - bucket rain gauge. When the rain gauge 1 detects that the accumulated water volume reaches 0.2 mm, the controller controls the driving mechanism 24 to start and drive the rain shelter 22 to flip.

[0047] In a specific example, the rain shelter 22 includes a shelter frame 221 and a shelter surface 222. One end of the shelter frame 221 is rotatably installed at the top of the support 21 and can be drivingly connected to the output end of the driving mechanism 24, and the other end can extend to the side of the rain reduction area 100 close to the rain enhancement area 200; the shelter surface 222 is slidably installed on the shelter frame 221 along the two ends of the shelter frame 221.

[0048] In a specific example, the shelter frame 221 includes a rotating rod 2211 and a plurality of connecting rods 2212. The axial direction of the rotating rod 2211 is arranged perpendicular to the two side ends of the rain reduction area 100 and is rotatably installed at the top of the support 21, and the rotating rod 2211 is drivingly connected to the output end of the driving mechanism. The plurality of connecting rods 2212 are arranged at intervals along the axial direction of the rotating rod 2211 and are vertically fixed on the rotating rod 2211, and the other end of the connecting rod 2212 can extend to the other side end of the rain reduction area 100.

[0049] In a specific example, the shelter surface 222 includes a plurality of sliding sleeves 2221 and a plurality of rain shelter cloths 2222. The plurality of sliding sleeves 2221 are slidably connected to the connecting rods 2212 in one-to-one correspondence, and one end of each sliding sleeve is fixed to the rotating rod 2211 by a lace, and the other end can extend to the other end of the connecting rod 2212. The plurality of rain shelter cloths 2222 are closely connected and / or arranged at intervals along the axial direction of the rotating rod 2211, and both ends of each rain shelter cloth 2222 are respectively connected to two adjacent sliding sleeves 2221. The rain shelter cloth 2222 is driven by the sliding sleeve 2221 to be unfolded or stored. Preferably, the sliding sleeve 2221 is a sleeve-like structure formed by sewing the rain shelter cloth. The length of the sliding sleeve 2221 after unfolding is equal to that of the connecting rod 2212, and the length of the rain shelter cloth 2222 when unfolded is also equal to that of the connecting rod 2212, so as to cover the entire rain reduction area 100 when sheltering from rain.

[0050] The number of the rain shelter cloths 2222 can be increased or decreased according to the need of the rain reduction amount. Figure 3 It is the arrangement mode of the rain shelter cloth when the rain reduction is 100%. Figure 6 It is one of the arrangement modes of the rain shelter cloth when the rain reduction is 25%. Figure 7 It is one of the arrangement modes of the rain shelter cloth when the rain reduction is 50%. Figure 8 It is one of the arrangement modes of the rain shelter cloth when the rain reduction is 75%.

[0051] Specifically, the rain shelter cloth 2222 is made of synthetic materials such as polyamide, polyester, and polyester fiber, and has the characteristics of waterproof, sunscreen, and anti-aging.

[0052] In a specific example, the width of the rain shield 2222 is greater than the distance between two adjacent connecting rods 2212, so that under the action of the gravity of rainwater, the rain shield 2222 can form a long strip "V"-shaped diversion groove that penetrates through both ends along the length direction of the connecting rod 2212 and has an open top. The end of the long strip "V"-shaped diversion groove far from the bracket 21 is arranged corresponding to the rainwater inlet of the rain collection tank 23, so that rainwater can be smoothly collected into the rain collection tank 23.

[0053] In a specific example, a filter screen is installed in the rain collection tank 23 to filter impurities in the rainwater.

[0054] In a specific example, a slip ring 25 is further provided. The slip ring 25 is connected to the side of the sliding sleeve 2221 far from the bracket 21 through a lacing and is slidably sleeved on the connecting rod 2212. The top of the rain collection tank 23 is connected to the slip ring 25. When the sliding sleeve 2221 slides, it drives the slip ring 25 to slide, thereby driving the rain collection tank 23 to slide, so that the rain collection tank 23 and the rain shield 2222 are recycled together to a position close to the rotating rod 2211, reducing the weight on the side of the rain shelter 22 far from the rotating rod 2211, reducing the resistance during the rotation of the rain shelter 22, and preventing the rain shelter 22 from being damaged.

[0055] In a specific example, a rain collection tank limit member 2213 is further provided. The rain collection tank limit member 2213 is fixed to the side of the connecting rod 2212 far from the rotating rod 2211 to limit the rain collection tank 23 to prevent the rain collection tank 23 from detaching or tearing the rain shield 2222 during the sliding of the rain collection tank 23 and causing damage. The rain collection tank limit member 2213 can be a limit rod or a limit convex ring. If it is a limit rod, the limit rod is fixed parallel to the rotating rod at the other ends of multiple connecting rods; if it is a limit convex ring, the outer diameter of the limit convex ring should be greater than the inner diameter of the slip ring 25.

[0056] In a specific example, a limit rod 26 is further provided. The limit rod 26 is fixed to the side of the bracket 21 far from the rain reduction area to limit the stored rain shield 2222 and the rain collection tank 23, so that when the rain shelter 22 rotates to the side far from the rain reduction area 100, the rain shield 2222 and the rain collection tank 23 will not slide off, reducing the resistance during the rotation of the rain shelter 22. At the same time, in the case of no rain, the rain shield 2222 is in a stored state, which can reduce the exposure to wind and sun and avoid damage and aging.

[0057] In a specific example, the driving mechanism 24 includes a driving motor 241, a driving gear 242 and a driven gear 243. The driving motor 241 is fixed on the bracket 21 and electrically connected to the controller. A gear box (not shown in the figure) is rotatably installed in the middle of the rotating rod 2211. Both the driving gear 242 and the driven gear 243 are installed in the gear box. The output shaft of the driving motor 241 passes through the gear box wall and is in transmission connection with the driving gear 242. The driving gear 242 is fixed on the output shaft of the driving motor 241. The driven gear 243 is fixed on the rotating rod 2211 and is in transmission connection with the driving gear 242. The controller controls the driving motor 241 to start, driving the driving gear 242 to rotate, and thus driving the driven gear 243 to rotate. Generally, the motor is a single-axis servo motor. According to the area size of the rain enhancement area 200, a double-axis driving motor 241 can also be set, and each output shaft thereof is provided with a driving gear 242, and a driven gear 243 is provided corresponding to each driving gear 242; or multiple groups of driving mechanisms 24 can also be set.

[0058] In a specific example, a driving motor braking assembly 27 is further provided. The driving motor braking assembly 27 includes a braking button 271 and a trigger rod 272. The braking button 271 is installed on the driving motor 241. The trigger rod 272 is fixed on the rotating rod 2211 and the trigger rod 272 can trigger the braking button 271 to control the braking of the driving motor 241. When the rotating rod 2211 rotates until the trigger rod 272 contacts the braking button 271, the driving motor 241 stops rotating. At this time, the blocking rod 2213 of the rain shelter 22 is slightly lower than the rotating rod 2211, so that rainwater can flow smoothly into the rain collection tank 23.

[0059] In a specific example, a support frame (not shown in the figure) can also be provided at the other end of the rain enhancement area 200, and the height of the support frame is lower than that of the bracket. When the rain shelter 22 shelters from rain, the blocking rod 2213 can be supported on the support frame to enhance the bearing capacity of the rain shelter 22.

[0060] In a specific example, a water diversion assembly 5 is further provided. The water diversion assembly 5 includes a water diversion pipe 51 and a rain collection hopper 52. The bottom of the water diversion pipe 51 is communicated with the rain collection barrel 3. The rain collection hopper 52 is fixed on the top of the water diversion pipe 51, and its bottom is closed and communicated with the water diversion pipe 51, and the top is open and can correspond to the drain port 231.

[0061] In a specific example, a filter screen is installed in the rain collection barrel 3 to filter impurities in the rainwater and prevent blockage during the pumping process of the water pump 41.

[0062] In a specific example, the rain augmentation mechanism 4 includes a water pump 41, a water delivery pipe 42, and multiple spray heads 43. The water pump 41 is electrically connected to the controller, and its water inlet is connected to the inside of the rain collection barrel 3 through a pipe. One end of the water delivery pipe 42 is connected to the water outlet of the water pump 41, and the other end extends into the rain augmentation area 200. The multiple spray heads 43 are arranged at intervals along the length direction of the water delivery pipe 42 and are installed on the water delivery pipe 42.

[0063] In a specific example, a water level sensor is installed inside the rain collection barrel 3, and the water level sensor is electrically connected to the controller. The water level sensor can adopt a float type water level sensor, which is used to monitor the water level inside the rain collection barrel 3. When the water level reaches the set value, the controller controls the water pump 41 to irrigate the rainwater in the rain collection barrel 3 into the rain augmentation area 200 through the spray heads 43.

[0064] In a specific example, a solar power supply component 6 is also provided. The solar power supply component 6 includes a solar panel and a storage battery. The solar panel is electrically connected to the storage battery, and the storage battery is electrically connected to the drive motor 241, the controller, the rain gauge, the water pump 41, and the water level sensor respectively, which is energy-saving and environmentally friendly.

[0065] Working principle:

[0066] In a rainless state, such as Figure 2 , the rain shelter is in the first position, the shed frame 221 is flipped outside the sample plot rain reduction area 100, and the end far from the support is in contact with the ground outside the rain reduction area 100. The rain collection box 23 is intercepted by the limiting rod 26, and the shed surface 222 is in a storage state. When the rain gauge 1 detects that the rainfall exceeds the set value, the controller controls the drive motor 241 to start, and through gear transmission, the rain shelter 22 is flipped. The rain shelter 22 gradually rotates from the outside of the sample plot rain reduction area 100 to directly above the rain reduction area 100. When the rain shelter 22 rotates to the second position and covers directly above the sample plot rain reduction area 100 and slopes downward, the rain collection box 23 slides towards the end under the action of gravity until it is intercepted by the blocking rod 2213. At the same time, it drives the rainproof cloth 2222 to unfold. When it slides to the end of the shed frame 221 and is intercepted by the blocking rod 2213, the rain collection box 23 stops sliding, and the rainproof cloth 2222 is also fully straightened. The trigger rod 272 in the middle of the rotating rod 2211 presses the braking button 271 to brake the drive motor 241. At this time, as Figure 1 shown, the rainwater gathers in the middle of the rainproof cloth 2222 and flows into the rain collection box 23. The rainwater in the rain collection box 23 flows into the rain collection barrel 3 through the drain port and the drainage component 5. When the float type water level sensor monitors that the water level in the rain collection barrel 3 reaches the set value, the controller controls the water pump 41 to start, and evenly sprays the collected rainwater on the sample plot rain augmentation area 200. After the rainfall ends, the rain shelter 22 is manually lifted and returned to the first position.
