Description

Technical Field

[0001] The present invention relates to the technical field of hydrological ecology, and in particular to a remote sensing monitoring device for hydrological ecology. Background Art

[0002] Traditional hydrological and ecological monitoring equipment mainly relies on observations from ground stations, such as setting up hydrological stations around rivers, lakes and other water bodies to measure parameters such as water level, flow, and water quality. Although this method has high accuracy, it has the problem of limited spatial coverage, and it is impossible to densely set up enough ground stations. With the advancement of the times, remote sensing technology and camera monitoring technology have emerged in the field of hydrological and ecological monitoring. Remote sensing technology has upgraded the data transmission method. Data can be transmitted from satellites to ground stations in a timely and stable manner, realizing efficient storage, processing and analysis. Camera monitoring technology can flexibly and comprehensively monitor data such as water surface temperature because its acceptable spectral range is constantly expanding. This is very important for studying hydrological phenomena such as water temperature changes and evaporation processes in lakes and rivers. Before implementation, the camera device can be simply mounted on the monitoring platform.

[0003] Although the technology of hydrological ecological monitoring equipment has been updated, some problems still exist, especially when monitoring water quality in the wild environment. Currently, rainwater is usually collected in a collection tube at a regular or quantitative manner and then monitored by a water quality monitor inside the machine. However, when the collection tube is sent into the machine body for water quality monitoring, external rainwater cannot be connected. Even if the volume of the collection tube is increased and connecting pipes are installed to save transportation operations, water quality monitoring in the wild environment requires not only rainwater collection and monitoring, but also the function of continuous sampling of river and lake water at different depths to obtain accurate and complete monitoring data. The above-mentioned changes cannot achieve continuous sampling at different depths. Summary of the invention

[0004] The present invention provides a remote sensing monitoring device for hydrological ecology, which solves the problem that hydrological ecological monitoring equipment in the related art does not have the functions of continuous sampling at different depths and continuous rainwater collection and monitoring.

[0008] As a further technical solution, it also includes: A retaining cylinder, wherein the retaining cylinder is arranged in the collecting cylinder groove, the diameter of the retaining cylinder is smaller than the diameter of the collecting cylinder groove, and the bottom of the retaining cylinder is higher than the bottom of the collecting cylinder groove; The filter layer is arranged at the bottom of the retaining cylinder, and the plurality of collecting ports are all located in the retaining cylinder and above the filter layer.

[0009] As a further technical solution, the collection and monitoring tube is L-shaped, and has a vertical section and a horizontal section. The vertical section has a plurality of collection ports, and one end of the horizontal section has the monitoring port. The filter layer is sleeved on the bottom of the vertical section, and the cross-sectional area of ​​the filter layer is equal to the cross-sectional area of ​​the retaining tube.

[0014] As a further technical solution, the long holes are arranged vertically, and the shortest distance between two adjacent long holes is greater than the maximum width of the collecting port.

[0015] The working principle and beneficial effects of the present invention are: Continuous collection, continuous sampling, and continuous monitoring: The improved collection tube tank with a larger volume can achieve uninterrupted collection. At the same time, several collection ports arranged vertically at intervals on the collection and monitoring tube can continuously sample water samples at different depths, continuously collect and monitor the corresponding data, and form a data chain to ensure more accurate and complete monitoring results.

DETAILED DESCRIPTION

[0020] In order to more clearly illustrate the embodiments of the present invention or the technical solutions in the prior art, the specific implementation methods of the present invention will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings described below are only some embodiments of the present invention. For ordinary technicians in this field, other drawings and other implementation methods can be obtained based on these drawings without creative work.

[0021] In order to simplify the drawings, only the parts related to the invention are schematically shown in each figure, and they do not represent the actual structure of the product. In addition, in order to simplify the drawings and facilitate understanding, in some figures, only one of the parts with the same structure or function is schematically shown, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0022] In this document, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0023] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0024] Reference Figure 1 to Figure 9, which is the first embodiment of the present invention, proposes a remote sensing monitoring device for hydrological ecology, including: a monitoring body 1, the monitoring body 1 has a collecting barrel 101; a remote sensing monitoring instrument 2, the remote sensing monitoring instrument 2 is arranged on the monitoring body 1, and is located on one side of the collecting barrel 101; a collecting monitoring tube 3, the collecting monitoring tube 3 is arranged in the collecting barrel 101, one end of the collecting monitoring tube 3 has a monitoring port 301, the side wall of the collecting monitoring tube 3 has a plurality of collecting ports 302, the plurality of collecting ports 302 are arranged at intervals along the vertical direction, and are all located in the collecting barrel 101, the collecting port 302 is connected to the collecting barrel 101, the monitoring port 301 passes through the inner wall of the collecting barrel 101, and is connected to the remote sensing monitoring instrument 2; a video monitoring instrument 4, the video monitoring instrument 4 is arranged on the monitoring body 1, and is electrically connected to the remote sensing monitoring instrument 2.

[0025] In this embodiment, the ecological monitoring device replaces the previous collection form of a single collection tube and adopts an "inner and outer sleeve" structure. The external larger collection tube groove 101 is used to collect rainwater uninterruptedly. At the same time, the collection tube groove 101 has a certain depth, so the collection monitoring tube 3 welded or detachably installed in the collection tube groove 101 is immersed in the collected rainwater, and a number of collection ports 302 arranged vertically on the side wall can achieve continuous sampling, and can target different depths. Compared with the traditional small collection tube for quantitative or timed rainwater collection, on the one hand, there is an intermittent problem, which cannot be avoided even if it is upgraded to a multi-collection tube switching mechanism. On the other hand, the process of sending the collection tube into the body for monitoring may occur, and this action cannot be eliminated. The monitoring port 301 of the collection monitoring tube 3 directly penetrates the entire inner wall of the collection tube groove 101, and the rainwater retained in the collection tube groove 101 collected in the collection port 302 is directly introduced into the remote sensing monitor 2, which also eliminates the sending action and directly connects the monitoring.

[0026] The ecological monitoring device can continuously collect rainwater for monitoring, and can also change the overall position, such as underwater, so that the collection tube 101 contains river and lake water of different depths, and then continuously sample and monitor the river and lake water of different depths to obtain accurate and complete data on the water quality of rivers and lakes at different depths, so as to understand the changes in the water quality of rivers and lakes in the vertical direction, and provide a basis for water resource assessment and pollution control, etc., because the monitoring instrument upgraded by remote sensing technology also needs to obtain water samples for monitoring, when the remote sensing monitor 2 receives the water sample from the monitoring port 301 for additional monitoring, it will be discharged into the water area through the pipeline, which will not affect subsequent monitoring.

[0027] After the entire ecological monitoring device is installed in a wild river or lake, the remote sensing monitor 2 and the video monitoring device 4 configured thereon synchronously complete data collection, processing and analysis in various dimensions. For example, when working underwater, the remote sensing monitor 2 works based on the principle of electromagnetic wave reflection and radiation. When it receives the collected water flow and monitors it, the sensor therein converts the data into an electrical signal or a digital signal, and performs preliminary signal processing, such as amplification and filtering. Finally, the processed signal is transmitted to the ground receiving station through the data transmission system on the satellite. The ground receiving station calculates specific hydrological and ecological information such as changes in water area, underwater vegetation coverage and biomass, and stores this information in a database for use by relevant researchers and decision makers; the video monitoring device 4 It works on the principle of optical imaging. During the operation of the monitoring subject 1, the hydrological and ecological target area is photographed according to the set shooting parameters, such as shooting angle, resolution, shooting time interval, etc. The photographed digital images are stored in the storage medium of the equipment and then transmitted to the ground processing center through the data transmission system. The image is processed by image processing software, including image enhancement (improving the clarity and contrast of the image), image classification (classifying and identifying different targets such as water bodies, vegetation, soil, etc. in the image), etc., to extract water surface temperature information, draw a water temperature distribution map, and calculate parameters such as water area changes by processing visible light images, thereby providing intuitive and detailed image data and related parameter information for hydrological and ecological research.

[0028] Furthermore, the collecting barrel groove 101 has an opening 102 , and the depth direction of the collecting barrel groove 101 is arranged vertically, and further comprises: a guide inclined plate 5 , which is arranged at the opening 102 of the collecting barrel groove 101 , and the guide inclined plate 5 is annular.

[0029] In the present embodiment, firstly, the guide inclined plate 5 is arranged at the opening 102 of the collecting tube groove 101, and its annular structure can effectively guide rainwater from different directions around to converge into the collecting tube groove 101. In the outdoor environment, the falling direction and landing point of rainwater are uncertain. The guide inclined plate 5 can increase the area and efficiency of rainwater collection, reduce the loss of rainwater due to splashing or flowing in other directions, ensure the collection of more sufficient rainwater samples, and improve the accuracy and representativeness of rainwater quality monitoring data.

[0030] Secondly, the material of the annular guide ramp 5 can be plastic, stainless steel or aluminum alloy. Plastic has the characteristics of light weight, which is convenient for installation and transportation of the device, especially when it needs to be frequently moved or multiple monitoring points need to be arranged in the field, which reduces the overall weight and reduces transportation costs and labor costs, but its strength is relatively low and it may deform in high temperature environments; stainless steel has high strength and good corrosion resistance, can withstand large external force impact, and is not easy to be damaged. Even if it is exposed to harsh environments such as wind, rain, dust, etc. for a long time in the field, it can maintain the stability and integrity of the structure. Therefore, considering comprehensively that stainless steel has certain advantages in the application of the guide ramp 5, it can make up for some defects to a large extent, and is a more suitable material choice for the guide ramp 5 in the remote sensing ecological camera device.

[0031] Furthermore, the cross-sectional area of ​​the guide inclined plate 5 is larger than the cross-sectional area of ​​the collecting barrel groove 101 , and further includes: a plurality of support rods 6 , each of which has a bending portion 601 at one end, the bending portion 601 passes through the guide inclined plate 5 and abuts against the guide inclined plate 5 , and the plurality of support rods 6 are arranged in a circle around the guide inclined plate 5 .

[0032] In this embodiment, since the cross-sectional area of ​​the guide inclined plate 5 is larger than the cross-sectional area of ​​the collecting tube groove 101, it can collect rainwater in a wider range, and the weight brought by the stainless steel material, it needs to be stably supported, so a number of support rods 6 are arranged along the circumference of the guide inclined plate 5, and penetrate through and abut the guide inclined plate 5 through the bending portion 601, which can provide a stable and uniform support force for the guide inclined plate 5 with a larger cross-sectional area. For example, in the wild environment, the guide inclined plate 5 may be affected by natural forces such as wind, rain, and snow. The presence of the support rods 6 can effectively prevent the guide inclined plate 5 from being deformed, tilted, or even damaged due to uneven force, thereby ensuring that it is always in good working condition, and continues to play the functions of guiding rainwater and blocking debris, thereby ensuring the smooth progress of rainwater collection work.

[0033] During the specific installation, first place the monitoring body 1 at the predetermined installation position and fix it. Then, according to the designed size and shape of the guide inclined plate 5, place several support rods 6 roughly evenly around the guide inclined plate 5, determine the position of each support rod 6 relative to the collecting barrel groove 101, so that they can form a stable support layout in the circumferential direction, pick up a support rod 6, align the bent portion 601 at one end of it with the pre-designed connecting hole or connecting part on the guide inclined plate 5 (if there is no connecting hole, the bent portion 601 can be directly pressed against the appropriate position of the guide inclined plate 5), and then force the bent portion 601 through the guide inclined plate 5 so that the bent portion 601 is tightly abutted against the guide inclined plate 5. According to the same method, the remaining support rods 6 are connected to the guide inclined plate 5 in turn. During the connection process, it is necessary to check the firmness of the connection between each support rod 6 and the guide inclined plate 5 to ensure that the bending part 601 is not loose or offset. Finally, the other end of the support rod 6 is welded, bolted or other reliable connection methods are used to the surrounding fixed structure to firmly fix the entire structure together, thereby completing the rainwater collection part of the remote sensing ecological camera device and providing a stable structural foundation.

[0034] Furthermore, it also includes: a baffle 7, which is arranged in the collecting tube groove 101, the diameter of the baffle 7 is smaller than the diameter of the collecting tube groove 101, and the bottom of the baffle 7 is higher than the bottom of the collecting tube groove 101; a filter layer 8, which is arranged at the bottom of the baffle 7, and a plurality of collecting ports 302 are all located in the baffle 7 and are all located above the filter layer 8.

[0035] In this embodiment, the retaining cylinder 7 itself plays a blocking role because the diameter of the retaining cylinder 7 is smaller than the diameter of the collecting cylinder groove 101 and the bottom is higher than the bottom of the collecting cylinder groove 101. Specifically, this structural design can make the rainwater first form a certain buffer in the annular area between the inner wall of the collecting cylinder groove 101 and the retaining cylinder 7, and at this time it does not contact the collecting monitoring pipe 3, and then pass through the filter layer 8 at the bottom of the retaining cylinder 7 to slowly and evenly enter the collecting port 302 inside the retaining cylinder 7, thereby limiting the flow direction of the incoming water. The bottom-up water storage sampling method is more stable and better utilizes the filtering effect of the filter layer 8. If the opposite form is adopted, not only will the filtering effect be weakened, but the water flow will also be turbulent and splash everywhere. Therefore, this form improves the reliability and representativeness of sample collection, which is conducive to obtaining more accurate rainwater quality monitoring data, and is of great significance for studying the changing laws of rainwater quality in the wild environment.

[0036] Process: Rainwater first stays briefly in the annular area between the inner wall of the collecting tube groove 101 and the outer wall of the retaining tube 7 to form a buffer. During this process, some smaller impurity particles begin to settle. At the same time, rainwater passes through the filter layer 8 at the bottom of the retaining tube 7. The filter layer 8 intercepts and filters fine impurities such as mud, suspended particles, etc. in the rainwater. After preliminary filtration, the rainwater enters the retaining tube 7. Finally, the rainwater entering the retaining tube 7 accumulates from bottom to top until it contacts the collection port 302 or several collection ports 302 are filled with rainwater. The rainwater will continuously pass through the collection port 302 and enter the remote sensing monitor 2 along the monitoring port 301 for monitoring.

[0037] Furthermore, the collecting and monitoring pipe 3 is L-shaped, and has a vertical section 303 and a horizontal section 304. The vertical section 303 has a plurality of collecting ports 302, and one end of the horizontal section 304 has a monitoring port 301. The filter layer 8 is sleeved on the bottom of the vertical section 303, and the cross-sectional area of ​​the filter layer 8 is equal to the cross-sectional area of ​​the retaining tube 7.

[0038] In this embodiment, the collecting and monitoring tube 3 is configured into an L shape, which is divided into a vertical section 303 and a horizontal section 304. First, the filter layer 8 is mounted on the bottom of the vertical section 303 of the collecting and monitoring tube 3, and the cross-sectional area is equal to the cross-sectional area of ​​the retaining tube 7. This design ensures that the rainwater entering the retaining tube 7 can be evenly filtered through the filter layer 8, avoiding the interference of the L shape, and solving the problem of insufficient rainwater filtration or slow filtration speed due to too small a filtration area.

[0039] Specifically on the collection and monitoring tube 3, the vertical section 303 has several collection ports 302, and one end of the horizontal section 304 has a monitoring port 301, which makes the process from rainwater collection to transmission smoother and more efficient, reduces the loss and pollution risk of rainwater during the collection and transmission process, and the combined structure of the L-shaped collection and monitoring tube 3, the retaining tube 7, and the filter layer 8 is relatively compact, which is convenient for integrated installation in the collection tube groove 101, and is convenient for staff to disassemble, clean and replace.

[0040] Furthermore, the horizontal section 304 has an enlarged diameter section 305 and a reduced diameter section 306 in sequence from close to to far from the monitoring port 301 .

[0041] Furthermore, it also includes: a filter ring 9, which is arranged in the expanded diameter section 305.

[0042] In this embodiment, the horizontal section 304 has an expansion section 305 and a reduction section 306 in sequence from close to to far away from the monitoring port 301. This special pipe diameter change structure can effectively adjust the flow rate and pressure of rainwater. After the rainwater passes through the reduction section 306 and the expansion section 305 in sequence, the flow rate will increase and the pressure will increase, thereby achieving rapid monitoring.

[0043] A filter ring 9 is further installed at the expanded diameter section 305 near the monitoring port 301. After the water flow is initially filtered through the filter layer 8 at the bottom of the retaining tube 7, some tiny impurities may still remain. After it is accelerated, most of the water flow will be closer to the pipe wall, and the filter ring 9 can intercept these impurities without affecting the flow rate too much, thereby greatly improving the purity of the rainwater samples entering the monitoring equipment, ensuring that the monitoring data can more accurately reflect the actual water quality of the rainwater, and providing more reliable data support for hydrological and ecological research.

[0044] This structural design integrates multiple functions such as filtration, water flow regulation and anti-clogging by combining the filter ring 9 with the expansion section 305 and the reduction section 306. In a limited space, it fully exerts the synergistic effect of various components and improves the function of the entire collection and monitoring tube 3.

[0045] Furthermore, it also includes: a cylinder 10, which is rotatably arranged in the vertical section 303 and is connected to the collection monitoring pipe 3. After the cylinder 10 rotates, the outer wall of the cylinder 10 is used to block or unblock the collection port 302.

[0046] In the present embodiment, the cylinder 10 is rotatably disposed in the vertical section 303 and can block or open the collection port 302 by rotation, which enables the device to accurately control the timing and amount of rainwater collection. For example, when rainwater samples are collected under specific time periods or specific rainfall conditions, the collection port 302 can be accurately opened or closed by controlling the rotation angle of the cylinder 10. When only a small amount of rainwater samples are needed for preliminary monitoring or comparative analysis, the cylinder 10 can partially block the collection port 302 to control the inflow speed and total amount of rainwater. When a large number of samples are needed for comprehensive monitoring, the cylinder 10 is rotated to a position where the collection port 302 is fully opened, thereby meeting different monitoring needs and experimental design requirements and improving the flexibility and controllability of rainwater collection.

[0047] Furthermore, the cylinder 10 is arranged vertically along the rotation axis, and has a plurality of long holes 1001 , which are arranged at intervals along the spiral direction. After the cylinder 10 rotates, one of the long holes 1001 is connected to or cancels the connection with part of the collecting port 302 .

[0048] Furthermore, the long holes 1001 are arranged vertically, and the shortest distance between two adjacent long holes 1001 is greater than the maximum width of the collecting port 302 .

[0049] In this embodiment, the connection between the long holes 1001 arranged at intervals along the spiral direction on the cylinder 10 and the collecting ports 302 realizes a more precise adjustment of the rainwater collection amount and flow rate, as well as the function of continuous sampling at different depths. By controlling the rotation angle of the cylinder 10, the connection between the long holes 1001 and some of the collecting ports 302 can be accurately controlled to collect and analyze continuous data results with trends. For example, when several collecting ports 302 are filled with river and lake water, as the cylinder 10 rotates, the height of the long holes 1001 connected to the collecting ports 302 gradually decreases, and deeper and deeper water samples are gradually collected for monitoring.

[0050] Specifically, the vertical section 303 can be symmetrically arranged with a plurality of collection ports 302 arranged at intervals along the vertical direction, and a plurality of long holes 1001 arranged along the spiral direction are symmetrically opened on both sides of the hollow cylinder 10 to improve the processing capacity; further, the shortest distance between two adjacent long holes 1001 is greater than the maximum width of the collection port 302, ensuring that the solid part of the outer wall of the cylinder 10 can be used to block the collection port 302 at any time to adapt to various collection and analysis scenarios.

[0051] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
