[0029] At present, a common long-term monitoring forest penetrating rain automatic measuring and collecting device mainly uses a groove type collector and a self-recording tipping bucket rain gauge for observation. The device mainly comprises a water collection tank, a blocking net, a fixed support, a water guide pipe, an automatic rain gauge and a water collection tank. The water collection tank is arranged on the fixed support, one end of the water collection tank is in a closed state, and the water outlet hole at the other end is connected with the water collection tank and the automatic rain gauge through the water guide pipe. The water collection tank is provided with a water outlet hole at the bottom, and the connection part of the water collection tank and the water collection tank is provided with a blocking net. When in use, the penetrating rain drops in the rain collection groove, the penetrating rain flows to the blocking net in the rain collection groove, the litter and other impurities in the forest are blocked, the penetrating rain passes through the blocking net into the water guide pipe, and then enters the automatic rain gauge for measurement, and finally is collected in the water collection tank.

[0030] The blocking net blocks the forest litter and the like, and prevents the forest litter and the like from entering the automatic rain gauge, but the litter is accumulated at the blocking net, and if not cleaned in time, the collection of the through rain is affected, so that a worker needs to clean regularly, and a tool needs to be used to shovel the litter, which is complicated and difficult to clean.

[0031] Therefore, the long-term monitoring forest through rain automatic measurement and collection device provided by the embodiments of the present disclosure can easily clean the impurities at the blocking net.

[0032] At least one embodiment of the present disclosure provides a long-term monitoring forest through rain automatic measurement and collection device, comprising: a rain collecting tank, wherein one end of the rain collecting tank is provided with a first opening, the first opening is connected with a blocking net, and the other end of the rain collecting tank is in a closed state, and the long-term monitoring forest through rain automatic measurement and collection device further comprises: a cleaning component, wherein the cleaning component comprises: a second opening, a baffle and a fixing member, the second opening is arranged on the bottom of the rain collecting tank, and the second opening is located at one end of the bottom of the rain collecting tank close to the first opening; the baffle is rotationally connected to the bottom of the rain collecting tank, the baffle is located at the second opening, the baffle is the same shape as the second opening, so as to open or close the second opening; and the fixing member is connected to the baffle, so as to fix the rotation position of the baffle.

[0033] In the long-term monitoring forest through rain automatic measurement and collection device provided by the embodiments of the present disclosure, the second opening is arranged on the bottom of the rain collecting tank, the baffle is rotationally connected to the bottom of the rain collecting tank, the baffle is located at the second opening, and the baffle is located at the horizontal position of the rain collecting tank. When the through rain is collected, the rain collecting tank is placed obliquely in the forest, the through rain drops in the rain collecting tank, the through rain passes through the baffle and then passes through the first opening. When the impurities are accumulated at the blocking net, the baffle is rotated to be away from the bottom of the rain collecting tank, so that the impurities fall from the second opening. In this way, the impurities at the blocking net can be easily cleaned out of the rain collecting tank.

[0034] The present disclosure will be described below through several specific embodiments. In order to keep the following description of the embodiments of the present disclosure clear and concise, the detailed description of known functions and known components can be omitted. When any component of the embodiments of the present disclosure appears in more than one figure, the component can be indicated by the same reference numeral in each figure.

[0035] Reference Figure 1 and Figure 3 , Figure 1 FIG. 1 is a schematic view of a three-dimensional structure of a rain collecting tank in the embodiments of the present disclosure; Figure 1 FIG. 2 is a schematic view of a three-dimensional structure of a rain collecting tank in the embodiments of the present disclosure; Figure 3 FIG. 3 is a side view of a cleaning component in a cleaning state in the embodiments of the present disclosure; and Figure 1 and Figure 3As shown, this embodiment of the present disclosure provides an automatic measurement and collection device for long-term monitoring of forest penetration rain, comprising: a rain collection trough 1, one end of which has a first opening 10, a barrier net connected to the first opening, and the other end of the rain collection trough 1 being closed; characterized in that it further comprises: a cleaning component 3, the cleaning component 3 comprising: a second opening 11, a baffle 30, and a fixing member; the second opening 11 is opened at the bottom of the rain collection trough 1, and the second opening 11 is located at the end of the bottom of the rain collection trough 1 near the first opening 10; the baffle 30 is rotatably connected to the bottom of the rain collection trough 1, the baffle 30 is located at the second opening 11, the baffle 30 and the second opening 11 have the same shape, so as to open or close the second opening 11; the fixing member is connected to the baffle 30 to fix the rotational position of the baffle 30.

[0036] The water collection trough 1 has a second opening 11 at its bottom, and a baffle 30 is rotatably connected to the second opening 11. When collecting penetrating rain, the baffle 30 closes the second opening 11. The water collection trough 1 is placed at an angle in the forest. Penetrating raindrops fall into the water collection trough 1, pass through the baffle 30, and then through the first opening 10. Impurities are blocked at the blocking net 2. When a large amount of impurities accumulate at the blocking net 2, the baffle 30 rotates away from the bottom of the water collection trough 1, allowing the impurities to fall from the second opening 11. This makes it easy to clean the impurities at the blocking net 2 from the water collection trough 1. The structure is simple and easy to manufacture. It should be understood that this embodiment does not impose specific limitations on the material of the water collection trough 1. It can be made of PVC, stainless steel, etc., and the specific material can be selected according to the actual situation, as long as it can be used for a long time in the forest. This embodiment also does not impose specific limitations on the specific size of the water collection trough 1. Different sizes of water collection trough 1 can be replaced according to the actual situation of the forest.

[0037] In the above embodiment, if the baffle 30 is directly rotatably connected to the second opening 11, there may be a large gap at the connection, causing some of the penetrating rain to leak out and not be collected well.

[0038] Therefore, this disclosure provides an improved approach.

[0039] Reference Figures 3 to 5 , Figure 4 This is a schematic diagram of the connection pipe between the cleaning component and the rainwater collection trough in an embodiment of this disclosure; Figure 5 for Figure 4 A magnified view of a portion of region B in the middle; as shown below. Figures 3 to 5 As shown, the cleaning component 3 also includes: a base plate 31, a connector 32, and a rotating shaft 33. The base plate 31 is connected to the side of the baffle 30 away from the rain collection trough 1, and the base plate 31 is larger than the second opening 11. The connector 32 is connected to the bottom of the outer side of the rain collection trough 1, and the connector 32 is located at the end of the rain collection trough 1 near the first opening 10. The rotating shaft 33 is fixedly connected to the connector, and the base plate 31 is rotatably connected to the rotating shaft 33.

[0040] The rotation of the baffle 30 at the second opening 11 is achieved by the rotation connection of the bottom plate 31 and the connecting piece 32, so that there is no large gap at the connection.

[0041] In the above embodiment, the rotation of the baffle 30 needs to be manually controlled. When it is found that the accumulated impurities are more, the baffle 30 is rotated away from the second opening 11, so that the impurities fall from the second opening 11. After the impurities fall, the baffle 30 needs to be rotated to be close to the second opening 11 and be flush with the bottom of the rainwater collecting groove 1, and then be locked.

[0042] Therefore, the embodiment provides an improved mode.

[0043] Referring to Figure 4 and Figure 5 , Figure 4 is a schematic view of a connection between a cleaning component and a rainwater collecting groove in the embodiment of the present disclosure; Figure 5 is Figure 4 a local enlarged view of the B area in FIG. 8. The cleaning component 3 further comprises a torsion spring 34, the torsion spring 34 is sleeved on the rotating shaft 33, one end of the torsion spring 34 abuts against the bottom plate 31, and the other end of the torsion spring 34 abuts against the connecting piece 32.

[0044] One end of the torsion spring 34 is connected to the bottom plate 31, and the other end of the torsion spring 34 is connected to the connecting piece 32. When the impurities on the baffle 30 accumulate more, the baffle 30 is rotated by gravity, and after the impurities on the baffle 30 completely fall, the baffle 30 returns to the original state under the action of the torsion spring 34.

[0045] In the above embodiment, the impurities may not accumulate much, so that the baffle is rotated by a small angle, and the impurities cannot fall. At this time, there is a certain influence on the collection of penetrating rain.

[0046] Therefore, the embodiment provides an improved mode.

[0047] Referring again to Figure 3 , the fixing member further comprises a first magnet 35 and a second magnet 36. The first magnet 35 is connected to one end of the bottom plate 31 away from the rotating shaft 33, and the first magnet 35 is located on the side of the bottom plate close to the baffle 30. The second magnet 36 is connected to the outer bottom of the water collecting groove 1, and the second magnet 36 is located on the side of the second opening 11 away from the rotating shaft 33. The ends of the first magnet 35 and the second magnet 36 close to each other are different magnetic poles, and the thicknesses of the first magnet 35 and the second magnet 36 are both 2-3 mm.

[0048] The first magnet 35 and the second magnet 36 have attractive force when close to each other, so that the baffle 30 does not rotate and does not affect the collection of the penetrating rain when the impurities at the blocking net 2 are not many. The thickness of the first magnet 35 and the second magnet 36 is 2-3 mm, so that the baffle 30 and the second opening 11 do not have large gaps due to the thickness of the first magnet 35 and the second magnet 36, and the collection of the penetrating rain is not affected.

[0049] In the above embodiment, only the impurities accumulated on the baffle 30 can be cleaned, and some impurities adhering to the bottom of the rainwater collecting groove 1 cannot be cleaned.

[0050] Therefore, the embodiment provides an improved mode.

[0051] Referring again to Figure 1 and Figure 2 , a groove 12 is formed in the groove wall of the rainwater collecting groove 1 along the groove direction, and the cleaning component 3 further comprises: an extension piece 37 and a sliding plate 38. The fixed end of the extension piece 37 is fixedly connected to the groove wall of the groove 12 close to the first opening 10. The sliding plate 38 is slidingly connected to the bottom of the rainwater collecting groove 1. One end of the sliding plate 38 is fixedly connected to the extension end of the extension piece 37, and the other end of the sliding plate 38 is slidingly connected to the groove wall of the rainwater collecting groove 1.

[0052] During the collection of the penetrating rain, the extension piece 37 is in an extended state, and the sliding plate 38 is located at the end of the rainwater collecting groove 1 away from the first opening 10. When cleaning is needed, the sliding plate 38 is slid to the second opening 11, and the extension piece 37 is retracted. Because one end of the sliding plate 38 abuts against the bottom of the rainwater collecting groove 1, some impurities adhering to the bottom of the rainwater collecting groove 1 are pushed to the second opening 11 and then fall from the second opening 11.

[0053] In the above embodiment, after the impurities on the bottom of the rainwater collecting groove 1 are cleaned, the sliding plate 38 needs to be controlled to return to the initial position.

[0054] Therefore, the embodiment provides an improved mode.

[0055] Referring to Figure 1 and Figure 2 , a spring 39 is sleeved on the extension piece 37. One end of the spring 39 is connected to the sliding plate 38, and the other end of the spring 39 is connected to the end of the groove 12 close to the first opening 10. A flexible piece 380 is connected between the sliding plate 38 and the bottom of the rainwater collecting groove 1.

[0056] When the telescopic part 37 is retracted, the spring 39 is compressed, when the sliding plate 38 slides to the second opening 11, the impurities in the groove fall from the second opening 11, under the action of the spring 39, the telescopic part 37 is extended, and the sliding plate 38 returns to the initial state. The sliding plate 38 is connected with the groove bottom of the rain collecting groove 1 through a flexible part 380, so that the sliding plate 38 is not in direct contact with the groove bottom of the rain collecting groove 1 during sliding, and damage is caused.

[0057] In the above embodiment, the baffle 30 needs to be smaller than the second opening 11 to block the second opening 11, and there is a small gap between the end of the baffle 30 away from the rotating shaft 33 and the second opening 11, and the penetrating rain may seep out from the gap.

[0058] Therefore, the embodiment of the present disclosure provides an improved mode.

[0059] Referring to Figure 1 , the end of the second opening 11 away from the blocking net 2 is connected with a first thin plate 110, the thickness of the first thin plate 110 is 1-3 mm, the length of the first thin plate 110 is the same as the groove width of the rain collecting groove 1, and the width of the first thin plate 110 is 1-2 cm.

[0060] When the baffle 30 rotates to block the second opening 11, a part of the first thin plate 110 is on the baffle 30, and the first thin plate 110 makes there be no gap between the groove bottom of the rain collecting groove 1 and the baffle 30, and the thickness of the first thin plate 110 is 1-3 mm, which does not affect the flow of the penetrating rain.

[0061] In the above embodiment, when the rainfall is very large, there is a lot of penetrating rain in the rain collecting groove 1, which cannot flow out from the first opening 10 quickly, and the penetrating rain does not flow out, and under the action of gravity, the baffle 30 rotates away from the second opening 11, so that the penetrating rain falls from the second opening 11, which affects the collection of the penetrating rain.

[0062] Therefore, the embodiment provides an improved mode.

[0063] Referring to Figure 1 , the center of the first thin plate 110 is connected with a second thin plate 111, the end of the second thin plate 111 away from the first thin plate 110 is connected to the first opening 10, the thickness of the second thin plate 111 is 1-3 mm, and the width of the second thin plate 111 is 2-3 cm.

[0064] The second thin plate 111 makes, when the rainfall is particularly large, the baffle 30 rotates away from the second opening 11, a part of the penetrating rain flows out from the second opening 11, and a part of the penetrating rain is guided to the first opening 10 through the second thin plate 111, so that even if the rainfall is particularly large, the collection of the penetrating rain is not affected.

[0065] Referring to Figure 6 , Figure 6A schematic diagram of the structure of the automatic measurement and collection device for long-term monitoring of forest throughfall provided in this embodiment of the disclosure. Figure 6 As shown, it also includes: a fixed bracket 4, a connecting pipe 5, a multi-channel pipe 6, a flexible hose 7, a tipping bucket rain gauge 8, a support component 80, and a collection bucket 9. The fixed bracket 4 is detachably connected to the bottom of the water collection tank 1. The fixed bracket 4 includes a first fixed bracket 40 and a second fixed bracket 41. The second fixed bracket 41 is higher than the first fixed bracket 40. The second fixed bracket 41 is connected to the bottom of the water collection tank 1 at the end away from the first opening 10, and the first fixed bracket 40 is connected to the bottom of the water collection tank 1 at the end near the first opening 10, so that the rain collection tank 1 is placed at an angle to facilitate the flow of penetrating rain. There are multiple connecting pipes 5, each... Each connecting pipe 5 is connected to a rain collection trough 1, with a minimum distance of 2m between adjacent rain collection troughs 1. One end of the connecting pipe 5 is fixedly connected to the first opening 10 of the rain collection trough 1. Multiple channels of the multi-channel pipeline 6 are respectively connected to the ends of the multiple connecting pipes 5 away from the rain collection trough 1. The flexible hose 7 is connected to another channel of the multi-channel pipeline 6. One end of the tipping bucket rain gauge 8 is connected to the end of the flexible hose 7 away from the multi-channel pipeline 6. The support member 80 is located below the tipping bucket rain gauge 8 and is used to support the tipping bucket rain gauge 8. The collection bucket 9 is connected to the tipping bucket rain gauge 8, is embedded in the ground, and is used to collect penetrating rain.

[0066] The penetrating rain that falls into the rain collection trough 1 flows through the first opening 1 to the connecting pipe 5, then through the multi-channel pipe 6 to the flexible hose 7, and then into the tipping bucket rain gauge 8. The tipping bucket rain gauge 8 can automatically record the rainfall, temperature and humidity of the penetrating rain. Finally, the penetrating rain enters the collection bucket 9 and is collected. The collection bucket 9 is embedded below the ground a, which reduces the temperature of the collected penetrating rain, reduces the growth of microorganisms and algae in the sample and the conversion of nutrients, and improves the quality of sample collection.

[0067] The above-disclosed embodiments are merely a few specific examples of the present invention. However, the embodiments of the present invention are not limited thereto, and any variations that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
