Description

Technical Field

[0001] The utility model relates to the technical field of forest ecological environment research, in particular to a rainwater collection device for forest ecological environment research. Background Art

[0002] The main form of rainfall passing through the forest canopy is throughfall, which is formed when the precipitation passes through the gaps in the canopy or the part of rainwater intercepted by branches and leaves and enters the forest in the form of raindrops. Collecting throughfall is of great significance for the study of forest ecological environment.

[0003] For example, the Chinese patent with the authorization announcement number: CN213329222U discloses a rainwater collection device for forest ecological environment research, including an upper tube body, a lower tube body, a water guide inner tube, a slide, an adjustment bolt handle, a movable rod, a water guide cloth, a tube cover, a water guide hose, a water cup, a cross partition, and a cross pedal. The water inlet structure composed of the movable rod and the water guide cloth of the utility model can be stored in the upper tube body, which is convenient for flexible opening or storage of the movable rod and the water guide cloth according to the needs of rainwater collection, and has the advantage of being easy to use; the utility model is an integrated structure, does not require on-site assembly, and is easy to carry; a detachable structure is adopted between the upper tube body and the lower tube body, which is not only convenient for loading and unloading the water cup, but also convenient for cleaning the upper tube body; the utility model also has the advantage of high stability.

[0004] When the movable rod in the above patent is extended out of the upper tube body, under the action of the torsion spring hinge, the movable rod rotates and the water guide cloth is stretched out, and the water guide cloth 7 encloses a bucket-shaped water inlet area. The movable rod in the above patent only relies on the elastic force of the torsion spring hinge to support the water guide cloth, and does not have a limiting fixing mechanism to limit and fix the movable rod. The stability of the movable rod is not good, and rainy days are often accompanied by wind. When the wind blows the water guide cloth, it is easy to cause the movable rod and the water guide cloth to gather in the middle, and the area of ​​the water inlet area changes accordingly, affecting the normal collection of rainwater, resulting in poor accuracy of rainwater collection, which is not conducive to the later research on the forest ecological environment and has certain limitations.

[0028] The latch mechanism includes a fixed cylinder 13 fixedly mounted on the limiting rod 9, the interior of the fixed cylinder 13 is movably connected with a movable block 14, the two sides of the movable block 14 are respectively fixedly connected with a latch 15 and a pull rod 16, a clamping spring 17 is fixedly connected on the movable block 14 and located on the outside of the pull rod 16, one end of the pull rod 16 away from the movable block 14 movably penetrates the fixed cylinder 13 and extends to the outside of the fixed cylinder 13, and the end of the latch 15 away from the movable block 14 movably penetrates the fixed cylinder 13 and extends to the through groove 10.

[0029] The clamping mechanism includes a movable block 18 slidably connected inside the device groove 11 , and the two sides of the movable block 18 are respectively fixedly connected with a clamping spring 19 and a clamping rod 20 , and the other end of the clamping rod 20 extends to the inside of one of the clamping holes 12 .

[0030] One side of the tube body 1 is fixedly connected to a threaded connection tube 22 through a bracket 21, the internal thread of the threaded connection tube 22 is connected to a water collecting tank 23, and the top of the threaded connection tube 22 is fixedly connected to a water guide hose 24, and the other end of the water guide hose 24 passes through the tube body 1 and is fixedly connected to the bottom of the water guide frame 3.

[0033] Working principle: When a rainwater collection device is needed to collect the penetrating rain in the forest, the device is first installed at the forest test point. During installation, the staff first level the ground at the test point with auxiliary tools, then abut the base 27 of the device against the leveled ground, and then insert the fixed steel bar 30 into the positioning hole 29, and then step on the pedal 31 with the foot to insert the fixed steel bar 30 into the soil, and complete the fixed installation of the rainwater collection device at the test point;

During the upward movement of the movable rod 5, the water guide frame 3, the sliding block 2, the clamping mechanism and the water guide hose 24 are synchronously moved upward. When the clamping rod 20 moves to a position opposite to another clamping hole 12, the elastic force of the clamping spring 2 19 pushes the movable block 2 18 and the clamping rod 20 to move, so that the clamping rod 20 is embedded in the clamping hole 12 opposite to it, and the sliding block 2 is limited and fixed again;

[0035] When the movable rod 5 moves out of the tube body 1, the pull rod 16 is pulled to drive the movable block 14 and the latch 15 to move. The movable block 14 moves to squeeze the clamping spring 17 to make it in a compressed state and store energy. The pull rod 16 is continuously pulled until the latch 15 completely exits the through slot 10. Then, the limit rod 9 and the movable rod 5 corresponding to the position of the latch 15 are rotated to move the fixed block 7 on the movable rod 5 into the through slot 10 on the limit rod 9, so that the pin hole on the fixed block 7 8 is opposite to the position of the latch 15, and then the pull rod 16 is loosened, and the latch 15 is pushed into the pin hole 8 by the elastic force of the clamping spring 17, so as to realize the fixed connection between the limit rod 9 and the movable rod 5, and repeat the above operation to fix the remaining movable rods 5 and the limit rod 9, so as to realize the bucket-shaped water guide cloth 6 is stretched to form a bucket-shaped water inlet area to collect rainwater, and the rainwater collected by the bucket-shaped water guide cloth 6 flows into the water collection tank 23 through the water guide frame 3 and the water guide hose 24 in turn for storage;

[0036] When rainwater collection is completed, the water collecting tank 23 can be disassembled by screwing the water collecting tank 23 to release the threaded connection with the threaded connection tube 22, which is simple and convenient to operate.

[0037] When the rainwater collecting device is no longer needed to collect rainwater, the pull rod 16 is pulled to drive the pin 15 to withdraw from the pin hole 8, thereby releasing the fixed connection between the movable rod 5 and the limit rod 9, and then the movable rod 5 and the limit rod 9 are reset by the elastic force of the torsion spring hinge, and then the clamping rod 20 is pressed to make it withdraw from the clamping hole 12, thereby releasing the limit fixation of the sliding block 2, and then the movable rod 5 is manually moved into the tube body 1, driving the sliding block 2 to move downward until the clamping mechanism moves to be opposite to the other clamping hole 12, and the clamping rod 20 is pushed to move to the clamping hole 12 opposite to it by the elastic force of the clamping spring 2 19, and the sliding block 2 is limited and fixed again, completing the storage of the movable rod 5 and part of the area of ​​the bucket-shaped water guide cloth 6 into the tube body 1, reducing the volume of the device and facilitating carrying.
