Description
TECHNICAL FIELD
[0001] The present application relates to the technical field of water area experimental sample collection, in particular to a mangrove system plant detritus collection device. BACKGROUND
[0002] The mangrove system plant detritus collection device is used for collecting plant detritus in a predetermined area of a mangrove so that experimenters can determine the carbon content of each plant category, combine flow rate data, and then obtain the carbon flux of transverse transport of carbon of different types of plant detritus. Quantifying the carbon flux of transverse transport of the mangrove system is a necessary link to establish a complete carbon budget list of the mangrove system.
[0003] The collection device in the prior art mainly collects plant detritus through a net bag. The plant detritus needs to enter the net bag from the bag opening of the net bag. Although a certain amount of plant detritus can be collected, the bag opening is usually small, so that only plant detritus in a small water area can be collected, thereby affecting the accuracy of the determination of the carbon flux.
[0004] Meanwhile, the existing collection device also controls the net bag to rise and fall with the water level through a buoyancy device such as foam, and guides the net bag through a sliding groove when the net bag rises and falls. Although this design can collect plant detritus on the water surface, it is difficult to collect plant detritus at a certain depth below the water surface, resulting in inaccurate determination of the carbon flux. Moreover, the overall structure is relatively complex, and the sliding groove is easily blocked by plant detritus, affecting the normal collection function, and the reliability is poor in actual use.
[0005] It should be noted that the information disclosed in the above background section is only used to strengthen the understanding of the background of the present disclosure, and therefore can include information that does not constitute prior art known to those of ordinary skill in the art.

[0034] For the purpose, technical solutions and advantages of the present application to be more clear, the following will be combined with the drawings of the embodiments of the present application to make further detailed description.
[0035] The technical solutions in the embodiments of the present application will be described clearly and completely in the following with reference to the drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all the other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.
[0036] The collecting device in the prior art mainly collects plant debris through a net bag, and usually can only collect plant debris in a small water area. Meanwhile, the existing collecting device is difficult to collect plant debris at a certain depth below the water surface. The above reasons result in that the determination of carbon flux is not accurate enough. Moreover, the overall structure of the collecting device in the prior art is relatively complex, the chute is easily blocked by plant debris, which affects the normal collection function, and the reliability is poor in actual use.
[0037] To solve the above technical problems, the present embodiment provides a mangrove system plant debris collecting device. Referring to Figure 1 , Figure 1 is a schematic view of the mangrove system plant debris collecting device in the embodiments of the present application. The mangrove system plant debris collecting device in the embodiments of the present application comprises a collecting net 1 and at least two upright columns 2.
[0038] The upright column 2 serves as the installation basis of the collecting net 1, so that the collecting net 1 can be distributed in a predetermined area of the water area. Each upright column 2 is fixed on the bottom of the water area or on the shore, and is arranged in a vertical direction of the flow direction of the water area.
[0039] For example, the first upright column 2 is fixed on the shore, and the remaining upright columns 2 are fixed on the bottom of the water area; or all the upright columns 2 are fixed on the bottom of the water area.
[0040] For example, the upright columns 2 are arranged in a vertical direction of the flow direction of the water area, or are arranged in a direction having a certain angle with the above-mentioned vertical direction.
[0041] The collecting net 1 is used for collecting plant debris, and the collecting net 1 is fixedly connected with each upright column 1. It can be understood that the collecting net 1 is unfolded through two adjacent upright columns 2 to realize the function of collecting plant debris. The collecting net 1 includes an exposed part above the water surface and an underwater part below the water surface in actual use, and is respectively used for collecting plant debris above and below the water surface.
[0042] For example, the upright column 2 is a pipe or a solid rod.
[0043] For the convenience of adjusting the length of each column 2 according to the depth of the water area, referring to Figure 2 Figure 2 is a schematic diagram of a threaded pipe spliced to form a column in the embodiment of the present application. The column 2 includes at least two threaded pipes 20, and the collection net 1 is fixedly connected with the threaded pipes 20 of the column 2. The end of each threaded pipe 20 is provided with a thread, and the threaded pipes 20 are connected in sequence through the threads. For example, one end of the threaded pipe 20 is provided with an internal thread 201, and the other end is provided with an external thread 202 matched with the internal thread 201. In this way, the threaded pipes 20 can be connected through the internal and external threads 202, realizing the splicing function and adjusting the total length according to the water depth of the installation position. For example, the column 2 on the shore is spliced by two threaded pipes 20, and the column 2 in the water is spliced by multiple threaded pipes 20, so as to ensure that the collection net 1 can cover the water area and the underwater area at the same time.
[0044] For example, after the collection net 1 collects the plant detritus samples, the operator collects the samples at each slack tide period.
[0045] The mangrove system plant detritus collection device of the above technical solution can improve the representativeness of plant detritus collection, and further improve the accuracy of carbon flux determination. Specifically, the collection device fixes the collection net 1 on the column 2, arranges the columns 2 in the vertical direction of the water flow direction, and makes the collection net 1 extend along the horizontal direction of the water area, so as to increase the collection area of the plant detritus. At the same time, since the collection net 1 is fixed on the column 2, the total length is changed by adjusting the number of threaded pipes 20 of the column 2, and the collection depth of the collection net 1 in the water is changed by adjusting the installation depth, so as to collect the plant detritus on and below the water surface at the same time. In this way, the mangrove system plant detritus collection device of the above technical solution can collect plant detritus in a larger area and at different depths in the water area, can improve the representativeness of plant detritus collection, and further can improve the accuracy of carbon flux determination. It is also important that the mangrove system plant detritus collection device of the above technical solution has a simple overall structure, does not need to use a buoyancy device and a sliding groove, and does not have the problem of the sliding groove being blocked by plant detritus. In actual use, it is more reliable and can effectively reduce the situation that the experiment process is affected due to the failure of the device in the use process.
[0046] In one embodiment of the connection between the threaded pipe 20 and the collection net 1, referring to Figure 3 Figure 3 Figure 1 is a schematic diagram of the connection between the threaded pipe and the collection net in the embodiment of the present application. The threaded pipe 20 is provided with at least two through holes 200 arranged in the axial direction, and the through holes extend in the radial direction of the threaded pipe 20; the two ends of the collection net 1 are fixedly provided with connecting ropes 10, and the connecting ropes 10 are tied on the through holes 200. In this way, the collection net 1 can adjust the through holes 200 tied by the connecting ropes 10 according to the required installation depth, adjust the relative position of the collection net 1 and the stand 2, and then facilitate the control of the installation depth of the collection net 1, which can greatly improve the applicability of the stand 1 and the convenience of the installation of the collection net 1. The spacing of the through holes 200 can be adjusted according to the required range.
[0047] For example, the spacing between each through hole 200 of the stand 2 is the same, and the same direction is convenient for the connection of the connecting rope 10 and the adjustment of the installation depth of the collection net 1.
[0048] In order to reduce the risk of rusting of the threaded pipe 20, the threaded pipe 20 is a stainless steel pipe.
[0049] For example, the threaded pipe 20 is 1 m long and has a wall thickness of 3-4 mm, such as 3 mm.
[0050] For example, the water area is a tidal ditch, and the stands 2 are arranged at intervals in the width direction of the water area, and the interval is 1.5-2.0 m, such as 1.8 m.
[0051] In order to ensure that the stand 2 is fixed firmly at the bottom of the water area, the bottom of the stand 2 is inserted into the bottom of the water area by 25-35 cm, such as 30 cm.
[0052] The mesh size of the collection net 1 can be set according to the size of the plant debris to be collected, and the mesh size of the collection net 1 is 1 cm x 1 cm.
[0053] In order to more comprehensively collect plant debris at different depths, the bottom of the collection net 1 is in contact with the bottom of the water area, and the top of the collection net 1 is 30-50 cm, such as 40 cm, above the water surface when the water level of the water area is the highest. This embodiment avoids the collection net 1 being submerged due to the rising of the water level, ensures the comprehensiveness of the debris collection, reduces the possibility of missing due to water flow scouring, and further improves the accuracy of the calculation of carbon flux.
[0054] In order to more comprehensively collect plant debris of sufficient width, the stands 2 are arranged at intervals in the width direction of the water area, and the total width of the collection net 1 is half of the width of the water area. Among them, the stands 2 can be arranged at equal intervals along the width direction of the water area to ensure that the collection net 1 can cover half of the entire water area. This layout not only ensures the collection efficiency, but also facilitates installation and maintenance, and facilitates the calculation of carbon flux in the later stage.
[0055] To further enhance the stability of the collection net 1 at the bottom of the water area, especially in the case of strong water flow, the above-mentioned collection device further comprises a counterweight 3. The counterweight 3 is connected to the bottom of the collection net 1 through a connecting member such as a rope, a chain or a strong fabric belt, ensuring that the collection net 1 can closely adhere to the bottom of the water area and is not easily washed away or moved by the water flow, while being able to straighten the collection net 1, thereby effectively collecting debris of various sizes.
[0056] For example, the configuration blocks are evenly arranged along the width direction of the collection net 1, in order to improve the flatness of the collection net 1 after being stretched.
[0057] In one embodiment in which the two ends of the collection net 1 are fixed on the stand 2, holes or grooves are provided on the stand 2 for fixing the collection net 1, and the collection net 1 is tied to the holes or grooves of the stand 2 by a rope, so that the collection net 1 cannot move relative to the stand 2. The tying position can be multiple, so as to improve the fixing effect of the collection net 1 on the stand 2.
[0058] In another embodiment in which the two ends of the collection net 1 are fixed on the stand 2, the collection net 1 is fixed on the stand 2 by the existing fishing net fixing method, which will not be described here.
[0059] In order to facilitate the collection of water level and water flow rate information of the water area, the mangrove system plant debris collection device further comprises a water level sensor and a flowmeter, which are respectively used to detect the water level and the water flow rate of the water area.
[0060] The water level sensor is selected from high-precision and waterproof water level sensors, such as pressure type water level sensors or ultrasonic water level sensors. The pressure type sensor calculates the water level height by measuring the water pressure, which is suitable for deep water areas; the ultrasonic sensor calculates the water level by emitting ultrasonic waves and receiving reflected waves, which is suitable for shallow water and obstacle-free environments. The water level sensor should be installed in the water area near the collection device to ensure that it can accurately reflect the water level changes in the working area of the device. For the ultrasonic sensor, it is necessary to ensure that there is no obstruction above it to ensure the accuracy of signal transmission. The installation position should take into account the influence of tides to ensure that it can work normally under extreme water level conditions. During operation, the sensor transmits real-time water level data to the control device of the collection device through wired or wireless methods (such as Bluetooth, LoRa, Wi-Fi, etc.). The control device is built-in with a microprocessor, which is responsible for receiving, analyzing and storing water level data, and displaying water level data through a display unit such as a display screen.
[0061] The flow velocity meter adopts Doppler flow velocity meter, electromagnetic flowmeter or acoustic flowmeter, etc. According to the characteristics of water area and the accuracy requirement, the appropriate flow velocity meter is selected. The Doppler flow velocity meter is suitable for measuring the water flow with high sediment concentration; the electromagnetic flowmeter has high requirement on water quality, but the measurement is accurate; the acoustic flowmeter is suitable for various complex water flow environment. The flow velocity meter should be installed at a certain distance downstream of the collection device to accurately capture the speed change of the water flow when passing through the collection area. When installing, the stability of the water flow direction should be considered to ensure the reliability of the measurement result. The flow velocity data collected by the detector is also transmitted to the control device through wired or wireless mode.
[0062] The above only describes the optional embodiments of the present application, and is not used to limit the present application. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the protection scope of the present application.
