[0029] At present, a common automatic measurement and collection device for long-term monitoring of forest penetrating rain mainly uses a groove collector and a self-recording tipping bucket rain gauge for observation. The device mainly includes: a water collection trough, a blocking net, a fixed bracket, a water pipe, an automatic rain gauge and a water collection tank. The water collection trough is set on the fixed bracket. One end of the water collection trough is closed, and the water outlet at the other end is connected to the water collection tank and the automatic rain gauge through the water pipe. The water collection tank is provided with a water outlet at the bottom, and a blocking net is provided at the connection between the water collection trough and the water collection tank. When in use, penetrating raindrops fall into the rain collection trough, and the penetrating rain flows from the rain collection trough to the blocking net. Impurities such as fallen leaves in the forest are blocked, and the penetrating rain enters the water pipe through the blocking net, and then enters the automatic rain gauge for measurement, and is finally collected in the water collection tank.

[0030] When the above device is in use, the blocking net will block impurities such as forest litter and prevent them from entering the automatic rain measuring cylinder. However, these litter will accumulate on the blocking net. If they are not cleaned in time, they will affect the collection of penetrating rain. Therefore, staff are required to clean them regularly, and tools are needed to shovel them out. The process is cumbersome and difficult to clean.

[0031] To this end, the embodiment of the present disclosure provides an automatic measurement and collection device for long-term monitoring of forest penetrating rain, which can easily clean up impurities on the blocking net.

[0032] At least one embodiment of the present disclosure provides an automatic measurement and collection device for long-term monitoring of forest penetration rain, comprising: a rain collecting trough, a first opening is opened at one end of the rain collecting trough, a blocking net is connected to the first opening, and the other end of the rain collecting trough is in a closed state, characterized in that it also includes: a cleaning component, the cleaning component includes: a second opening, a baffle and a fixing part, the second opening is opened at the bottom of the rain collecting trough, and the second opening is located at one end of the bottom of the rain collecting trough close to the first opening; the baffle is rotatably connected to the bottom of the rain collecting trough, the baffle is located at the second opening, and the baffle has the same shape as the second opening to open or close the second opening; the fixing part is connected to the baffle to fix the rotation position of the baffle.

[0033] In the automatic measurement and collection device for long-term monitoring of forest penetrating rain provided by the above-mentioned embodiment of the present invention, a second opening is opened through the bottom of the water collecting trough, and the baffle is rotatably connected to the bottom of the rain collecting trough. The baffle is located at the second opening. The baffle is located at a position parallel to the rain collecting trough. When collecting penetrating rain, the water collecting trough is tilted and placed in the forest. The penetrating raindrops fall into the water collecting trough. The penetrating rain will pass through the baffle and then through the first opening. When a large amount of impurities are accumulated at the blocking net, the baffle is rotated away from the bottom of the rain collecting trough to allow the impurities to fall from the second opening, so that it is easier to clean the impurities at the blocking net from the rain collecting trough.

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

[0035] Reference Figure 1 and Figure 3 , Figure 1 It is a schematic diagram of the three-dimensional structure of the rainwater collecting trough in the embodiment of the present disclosure; Figure 1 It is a schematic diagram of the three-dimensional structure of the rainwater collecting trough in the embodiment of the present disclosure; Figure 3 2 is a side view of the cleaning component in the cleaning state in the embodiment of the present disclosure; Figure 1 and Figure 3As shown, the embodiment of the present disclosure provides an automatic measurement and collection device for long-term monitoring of forest penetration rain, including: a rain collecting trough 1, a first opening 10 is opened at one end of the rain collecting trough 1, a blocking net is connected to the first opening, and the other end of the rain collecting trough 1 is in a closed state, characterized in that it also includes: a cleaning component 3, the cleaning component 3 includes: a second opening 11, a baffle 30 and a fixing part, the second opening 11 is opened at the bottom of the rain collecting trough 1, and the second opening 11 is located at one end of the bottom of the rain collecting trough 1 close to the first opening 10; the baffle 30 is rotatably connected to the bottom of the rain collecting trough 1, the baffle 30 is located at the second opening 11, and the baffle 30 has the same shape as the second opening 11 to open or close the second opening 11; the fixing part is connected to the baffle 30 to fix the rotation position of the baffle 30.

[0036] The bottom of the water collecting trough 1 is provided with a second opening 11, 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 collecting trough 1 is tilted and placed in the forest. The penetrating rain drops into the water collecting trough 1. The penetrating rain passes through the baffle 30 and then passes through the first opening 10. Impurities are blocked at the blocking net 2. When more impurities are accumulated at the blocking net 2, the baffle 30 rotates away from the bottom of the rain collecting trough 1 to allow the impurities to fall from the second opening 11. In this way, it is easy to clean the impurities at the blocking net 2 from the rain collecting trough 1. The structure is simple and easy to manufacture. It should be understood that the material of the rain collecting trough 1 is not specifically limited in this embodiment. It can be PVC material or stainless steel material, etc. It can be selected according to actual conditions and can be used for a long time in the forest. The specific size of the rain collecting trough 1 is not specifically limited in this embodiment. Rain collecting troughs 1 of different sizes can be replaced according to the actual conditions of the forest.

[0037] In the above embodiment, if the baffle 30 is directly rotatably connected to the second opening 11, a large gap may exist at the connection, so that a part of the penetrating rain is lost and cannot be well collected.

[0038] To this end, the embodiments of the present disclosure provide an improved approach.

[0039] Reference Figures 3 to 5 , Figure 4 It is a schematic diagram of the connection pipe between the cleaning component and the rainwater collecting gutter in the embodiment of the present disclosure; Figure 5 for Figure 4 A partial enlarged view of area B in the middle; Figures 3 to 5 As shown, the cleaning component 3 also includes: a bottom plate 31, a connecting piece 32, and a rotating shaft 33. The bottom plate 31 is connected to the side of the baffle 30 away from the rain collecting trough 1, and the bottom plate 31 is larger than the second opening 11; the connecting piece 32 is connected to the outer bottom of the rain collecting trough 1, and the connecting piece 32 is located at one end of the rain collecting trough 1 close to the first opening 10; the rotating shaft 33 is fixedly connected to the connecting piece, and the bottom plate 31 is rotatably connected to the rotating shaft 33.

[0040] The baffle 30 is rotated at the second opening 11 by the rotational connection between the bottom plate 31 and the connecting member 32, so that no large gap exists at the connection.

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

[0042] To this end, this embodiment provides an improved approach.

[0043] Reference Figure 4 and Figure 5 , Figure 4 It is a schematic diagram of the connection pipe between the cleaning component and the rainwater collecting gutter in the embodiment of the present disclosure; Figure 5 for Figure 4 A partial enlarged view of the area B in the middle; the cleaning component 3 also includes: 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 member 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 member 32. When a lot of impurities are accumulated on the baffle 30, the baffle 30 is rotated by gravity, and when the impurities on the baffle 30 are completely dropped, the torsion spring 34 returns to the original state.

[0045] In the above embodiment, there may not be much impurities accumulated, so that the impurities cannot fall down when the baffle is rotated at a small angle. At this time, there is a certain impact on the collection of penetrating rain.

[0046] To this end, this embodiment provides an improved approach.

[0047] Refer again Figure 3 The fixing member also includes: a first magnet 35 and a second magnet 36, the first magnet 35 is connected to the 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 tank 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 second magnet 36 and the first magnet 35 that are close to each other have different magnetic poles, and the thickness of the first magnet 35 and the second magnet 36 are both 2-3mm.

[0048] The first magnet 35 and the second magnet 36 have attraction when they are close to each other. When there are not many impurities in the blocking net 2, the baffle 30 will not rotate, and the collection of the penetrating rain will not be affected. The thickness of the first magnet 35 and the second magnet 36 are both 2-3mm, which avoids the situation where a large gap appears between the baffle 30 and the second opening 11 due to the thickness of the first magnet 35 and the second magnet 36 being too thick, thereby affecting the collection of the penetrating rain.

[0049] In the above embodiment, only the impurities accumulated on the baffle 30 can be cleaned, and some impurities beside the second opening 11 and in the rain collecting trough 1 and attached to the bottom of the rain collecting trough 1 cannot be cleaned.

[0050] To this end, this embodiment provides an improved approach.

[0051] Refer again Figure 1 and Figure 2 A groove 12 is provided on the groove wall of the rain collecting trough 1 along the groove direction, and the cleaning component 3 also includes: a telescopic member 37 and a slide plate 38, the fixed end of the telescopic member 37 is fixedly connected to the groove wall of the groove 12 near the first opening 10; the slide plate 38 is slidably connected to the groove bottom of the rain collecting trough 1, one end of the slide plate 38 is fixedly connected to the telescopic end of the telescopic member 37, and the end of the slide plate 38 away from the telescopic rod 37 is slidably connected to the groove wall of the rain collecting trough 1.

[0052] When collecting penetrating rain, the telescopic member 37 is in an extended state, and the slide plate 38 is located at the end of the rain collecting trough 1 away from the first opening 10. When cleaning is required, the slide plate 38 is slid toward the second opening 11, and the telescopic member 37 contracts. Because one end of the slide plate 38 abuts against the bottom of the rain collecting trough 1, some impurities attached to the bottom of the rain collecting trough 1 are pushed to the second opening 11 and fall from the second opening 11.

[0053] In the above embodiment, after the impurities at the bottom of the rainwater collecting trough 1 are cleaned, it is necessary to control the slide plate 38 to return to the initial position.

[0054] To this end, this embodiment provides an improved approach.

[0055] Reference Figure 1 and Figure 2 A spring 39 is sleeved on the telescopic member 37, one end of the spring 39 is connected to the slide plate 38, and the other end of the spring 39 is connected to one end of the groove 12 close to the first opening 10. A flexible member 380 is connected between the slide plate 38 and the bottom of the rain collecting trough 1.

[0056] When the telescopic member 37 contracts, the spring 39 is compressed. When the slide plate 38 slides to the second opening 11, impurities in the trough fall from the second opening 11. Under the action of the spring 39, the telescopic member 37 extends, and the slide plate 38 returns to its initial state. A flexible member 380 is connected between the slide plate 38 and the bottom of the rain collecting trough 1, so that during the sliding process, the slide plate 38 does not directly contact the bottom of the rain collecting trough 1 to cause damage.

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

[0058] To this end, the embodiments of the present disclosure provide an improved approach.

[0059] Reference Figure 1 The end of the second opening 11 away from the blocking net 2 is connected to 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 width of the rainwater collecting gutter 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 portion of the first thin plate 110 is on the baffle 30, and the first thin plate 110 leaves no gap between the bottom of the sump 1 and the baffle 30. The thickness of the first thin plate 110 is 1-3 mm, which will not affect the flow of penetrating rain.

[0061] In the above embodiment, when the rainfall is very heavy, there is a lot of penetrated rain in the sump 1 and it cannot flow out from the first opening 10 quickly. The penetrated rain does not flow out because the baffle 30 rotates away from the second opening 11 due to gravity, causing the penetrated rain to fall from the second opening 11, affecting the collection of the penetrated rain.

[0062] To this end, this implementation provides an improved approach.

[0063] Reference Figure 1 A second thin plate 111 is connected to the center of the first thin plate 110, and one 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 is 1-3 mm, and the width of the second thin plate 111 is 2-3 cm.

[0064] The second thin plate 111 allows the baffle 30 to rotate away from the second opening 11 when the rainfall is particularly heavy, and part of the penetrating rain flows out from the second opening 11, while part is guided to the first opening 10 through the second thin plate 111, so that even if the rainfall is particularly heavy, it will not affect the collection of the penetrating rain.

[0065] Reference Figure 6 , Figure 6This is a schematic diagram of the structure of the automatic measurement and collection device for long-term monitoring of forest penetration rain provided by the embodiment of the present disclosure. Figure 6 As shown, it also includes: a fixed bracket 4, a connecting pipe 5, a multi-channel pipeline 6, a hose 7, a tipping bucket rain gauge 8, a support 80, and a collecting bucket 9. The fixed bracket 4 is detachably connected to the bottom of the water collecting 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 end of the water collecting tank 1 away from the first opening 10. The first fixed bracket 40 is connected to the bottom of the end of the water collecting tank 1 close to the first opening 10, so that the rain collecting tank 1 is tilted to facilitate the flow of penetrating rain; there are multiple connecting pipes 5, each Each connecting pipe 5 is connected to a rain collecting trough 1, and the interval between two adjacent rain collecting gutters 1 is at least 2m. One end of the connecting pipe 5 is fixedly connected to the first opening 10 of the rain collecting trough 1; multiple channels of the multi-channel pipeline 6 are respectively connected to one end of the multiple connecting pipes 5 away from the rain collecting trough 1; the hose 7 is connected to the other channel of the multi-channel pipeline 6; one end of the tipping bucket rain gauge 8 is connected to the end of the 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 collecting bucket 9 is connected to the tipping bucket rain gauge 8, and the collecting bucket 9 is embedded in the ground, and the collecting bucket 9 is used to collect penetrating rain.

[0066] The through rain falling into the rain collecting trough 1 flows to the connecting pipe 5 through the first opening 1, flows to the hose 7 through the multi-channel pipeline 6, and then enters the tipping bucket rain gauge 8. The tipping bucket rain gauge 8 can automatically record the rainfall, temperature and humidity of the through rain. Finally, the through rain enters the collecting barrel 9 to be collected. The collecting barrel 9 is embedded under the ground a to reduce the temperature of the collected through rain, reduce the growth of microorganisms and algae in the sample and the conversion of nutrients, and improve the collection quality of the sample.
