Description

Technical Field

[0001] The invention belongs to the technical field of agricultural monitoring, and in particular relates to an agricultural meteorological monitoring station. Background Art

[0002] Agriculture refers to an important industry in the national economy, including five industries: planting, forestry, animal husbandry, fishery, and sideline industries. In agricultural meteorological monitoring, it is usually necessary to monitor basic meteorological information such as environmental temperature and humidity, rainfall, etc. However, in monitoring related to fisheries, it is necessary not only to monitor basic meteorological information, but also to sample and analyze pond water.

[0003] In the monitoring of fisheries, the commonly used means in the prior art is to install a counterweight base at the bottom of the pond, connect the floating platform by setting a retractable connecting rod, so that the floating platform floats on the surface of the pond, and set meteorological monitoring equipment on the surface of the floating platform to monitor basic meteorological information. At the same time, in order to facilitate sampling of water bodies at different depths, people will also install multiple equidistantly distributed sampling tubes along the telescopic connecting rod to collect water in layers.

[0004] However, after analysis, it was found that when the seasons change, the water level in the pond will rise or fall, and the various sampling tubes will not be able to adaptively adjust to an equidistant arrangement according to the changes in water level, which is not conducive to stratified sampling of pond water.

DETAILED DESCRIPTION

[0035] In order to enable those skilled in the art to better understand the present invention, the technical solution of the present invention is further described below in conjunction with the accompanying drawings and embodiments.

[0036] Embodiment 1, as Figures 1 to 3 An agricultural meteorological monitoring station shown in the figure includes a floating platform 100, a counterweight base 110, a vertically arranged upper connecting rod 120 and a vertically arranged lower connecting rod 121, a meteorological monitoring component is arranged on the surface of the floating platform 100, a slide groove is provided in the lower connecting rod 121, a slide rod 122 slidably connected to the slide groove is fixedly connected to the bottom of the upper connecting rod 120, the upper connecting rod 120 is fixedly connected to the bottom of the floating platform 100, and the bottom of the lower connecting rod 121 is fixedly connected to the counterweight base 110;

[0037] During the installation process, by fixing the counterweight base 110 to the bottom of the pond, the upper connecting rod 120 forms a telescopic structure with the slide groove of the lower connecting rod 121 through the slide rod 122, so that the floating platform 100 can float on the water surface of the pond, and the meteorological monitoring component on the surface of the floating platform 100 can monitor the meteorological environment data of the pond.

[0038] A water sampling mechanism is provided between the upper connecting rod 120 and the lower connecting rod 121. The water sampling mechanism includes two fixed sampling tubes 130 and a plurality of movable sampling tubes 131. Each fixed sampling tube 130 and each movable sampling tube 131 is provided with an electric valve 1301. Both fixed sampling tubes 130 are provided with a fixing block 1302. The two fixing blocks 1302 are respectively fixed to the lower end of the upper connecting rod 120 and the upper end of the lower connecting rod 121.

[0039] Each movable sampling tube 131 is installed with a movable block 1311, and the upper connecting rod 120 and the lower connecting rod 121 are provided with a longitudinal positioning slide rail 132. Each movable block 1311 located on the upper connecting rod 120 is slidably connected to the longitudinal positioning slide rail 132 of the upper connecting rod 120, and each movable block 1311 located on the lower connecting rod 121 is slidably connected to the longitudinal positioning slide rail 132 of the lower connecting rod 121.

[0040] like Figures 1 to 3 As shown, the fixed sampling tube 130 and the movable sampling tube 131 are respectively arranged along the upper connecting rod 120 and the lower connecting rod 121, so that each movable sampling tube 131 and each fixed sampling tube 130 can sample water at multiple depths in the pond;

[0041] At the same time, if Figures 1 to 3 As shown, the two fixed sampling tubes 130 are respectively connected to the lower end of the upper connecting rod 120 and the upper end of the lower connecting rod 121, so that for the upper connecting rod 120, multiple movable sampling tubes 131 and one fixed sampling tube 130 are installed in sequence from top to bottom, and for the upper connecting rod 121, one fixed sampling tube 130 and multiple movable sampling tubes 131 are installed in sequence from bottom to top, and as can be seen from the above, the movable sampling tube 131 is slidably connected to the longitudinal positioning slide rails 132 of the upper connecting rod 120 and the lower connecting rod 121 through the movable block 1311, so that the movable sampling tube 131 can slide longitudinally relative to the upper connecting rod 120 and the lower connecting rod 121, respectively.

[0042] Two adjacent movable sampling tubes 131, between the fixed sampling tube 130 and the closest movable sampling tube 131, and between two adjacent fixed sampling tubes 130 are all arranged at equal distances. Two adjacent movable sampling tubes 131, between the fixed sampling tube 130 and the closest movable sampling tube 131, and between two adjacent fixed sampling tubes 130 are all connected through a first telescopic pleated tube 1331. A sampling pump 134 is installed on the surface of the floating platform 100. The movable sampling tube 131 located at the uppermost side of the upper connecting rod 120 is connected to the sampling pump 133 through a second telescopic pleated tube 1332. A drainage pipe 1341 is also provided at the output end of the sampling pump 133.

[0043] like Figures 1 to 3As shown, two adjacent movable sampling tubes 131, between a fixed sampling tube 130 and the nearest movable sampling tube 131, and between two adjacent fixed sampling tubes 130 are equidistantly arranged, thereby ensuring that each movable sampling tube 131 and each fixed sampling tube 130 are equidistantly positioned under the pond water, and the telescopic connection between the sampling tubes is ensured by the first telescopic corrugated tube 1331, and the telescopic connection between the uppermost movable sampling tube 131 and the sampling pump 133 is ensured by the second telescopic corrugated tube 1332.

[0044] A spacing adjustment mechanism is also provided between the upper connecting rod 120 and the lower connecting rod 121. The spacing adjustment mechanism is used to adjust the spacing between two adjacent active sampling tubes 131 and between the fixed sampling tube 130 and the closest active sampling tube 131. The two fixed blocks 1302 and each active block 1311 are both installed with a first hinge seat 1351. A second hinge seat 1352 is provided in the middle position of two adjacent first hinge seats 132. Two adjacent first hinge seats 1351 and the second hinge seat 1352 therebetween are jointly hinged with two hinge rods 1353 to form a V-shaped hinge structure.

[0045] The spacing adjustment mechanism includes an upper slide rail 1361 and a lower slide rail 1362 arranged vertically, the upper slide rail 1361 and the lower slide rail 1362 are telescopically and slidably connected, the second hinge seat 1352 corresponding to the two fixed blocks 1302 is fixedly connected to the upper slide rail 1361, and the remaining second hinge seats 1352 on the upper and lower sides are slidably connected to the upper slide rail 1361 and the lower slide rail 1362 respectively, the counterweight base 110 is provided with a transverse positioning slide rail 137, and the lower end of the lower slide rail 1362 is provided with a positioning slider 1363 matching the transverse positioning slide rail 137;

[0046] The fixed block 1302 located on the upper connecting rod 120 is also provided with a transverse positioning rod 1381, which is located in the middle position of the two fixed blocks 1302. The second hinge seat 1352 corresponding to the two fixed blocks 1302 is provided with a positioning block 1382, and the transverse positioning rod 1381 passes through the positioning block 1382 laterally.

[0047] by Figures 1 to 3 As shown, Figures 1 to 3 As shown, the floating platform 100 floats on the surface of the pond, so that the extension of the upper connecting rod 120 relative to the lower connecting rod 121 is related to the water surface height of the pond;

[0048] When the water level in the pond drops, the height of the floating platform 100 drops as the water level drops, so the fixing block 1302 fixed to the upper connecting rod 120 will move downward and approach the fixing block 1302 fixed to the lower connecting rod 121. Since the positioning block 1382 is arranged on the second hinge seat 1352 corresponding to the two fixing blocks 1302, and the second hinge seat 1352 is fixed to the upper slide rail 1361, and the lateral positioning rod 1381 traverses through the positioning block 1382, the upper connecting rod 120 The upper slide rail 1361 will be lowered synchronously, and the upper slide rail 1361 will move downward relative to the lower slide rail 1362, so that the first hinge seat 1351 corresponding to the two fixed blocks 1302 will drive the second hinge seat 1352 fixed to the upper slide rail 1361 through the transmission of the hinge rod 1353, driving the upper slide rail 1361 and the lower slide rail 1362 to move synchronously laterally away from the upper connecting rod 120, and the positioning slider 1363 of the lower slide rail 1362 will slide laterally along the lateral positioning slide rail 137;

[0049] During this process, the remaining second hinged seats 1352 corresponding to the upper connecting rod 120 and the lower connecting rod 120 will slide downwards respectively relative to the upper slide rail 1361 and the lower slide rail 1362, and through the V-shaped hinged structure composed of the two adjacent first hinged seats 1351, the second hinged seats 1352 and the two hinged rods 1353, the distances between the two adjacent active sampling tubes 131, between the fixed sampling tube 130 and the closest active sampling tube 131, and between the two adjacent fixed sampling tubes 130 are synchronously reduced and kept equidistant, so that when the water level of the pond is lowered in the rainy season and the total height of the upper connecting rod 120 and the lower connecting rod 121 is reduced, the sampling tubes can be kept equidistantly distributed, so that the pond can be sampled evenly and equidistantly when sampling water.

[0050] Similarly, when the water level in the pond rises, the height of the floating platform 100 rises with the water level, the upper connecting rod 120 will rise synchronously with the upper slide rail 1361, the two fixed blocks 1302 will move away, and the remaining second hinged seats 1352 corresponding to the upper connecting rod 120 and the lower connecting rod 120 will slide upward relative to the upper slide rail 1361 and the lower slide rail 1362 respectively. Through the V-shaped hinged structure composed of two adjacent first hinged seats 1351, the second hinged seat 1352 and the two hinged rods 1353, the distances between two adjacent active sampling tubes 131, between the fixed sampling tube 130 and the closest active sampling tube 131, and between two adjacent fixed sampling tubes 130 are synchronously increased and maintained at an equal distance. In this way, when the water level of the pond rises in the rainy season and the total height of the upper connecting rod 120 and the lower connecting rod 121 increases, the sampling tubes can be evenly distributed, so that the pond can be sampled evenly and evenly when sampling water.

[0051] Therefore, in this embodiment, the specific workflow is as follows:

[0052] ① The counterweight base 110 is installed at the bottom of the pond, and floats on the surface of the pond through the floating platform 100. The counterweight base 110 and the floating platform 100 are connected by sliding through the upper connecting rod 120 and the lower connecting rod 121, so as to adapt to the water surface height;

[0053] ② The meteorological monitoring component of the floating platform can monitor the environmental data of the pond, and can use the water sampling mechanism to perform stratified sampling of the pond water. By setting the spacing adjustment mechanism, when the water level of the pond rises or falls, the various sampling tubes of the water sampling mechanism can always be evenly distributed in the water body. Specifically, a depth locator can be installed on each sampling tube. When sampling, single-depth sampling is performed. The corresponding electric valve 1301 at the sampling depth is opened, and all other electric valves 1301 are closed. The water at this depth is pumped in by the sampling pump 134, and discharged through the drain pipe 1341 for collection.

[0054] As a further description of the meteorological monitoring component in this embodiment, Figure 1 As shown, a vertical pole 101 is installed on the surface of the floating platform 100, and the meteorological monitoring component includes a solar panel 102, a battery pack 103, a rain gauge 104, a temperature monitor 105, a humidity monitor 106 and a wind speed monitor 107;

[0055] The solar panel 102, the rain gauge 104 and the wind speed detector 107 are all mounted on the upper side of the vertical pole 101. A canopy 108 is also provided in the middle of the vertical pole 101. The temperature monitor 105 and the humidity monitor 106 are mounted on the lower side of the vertical pole 101.

[0056] The battery pack 103 is electrically connected to the solar panel 102 , and the rain gauge 104 , the temperature monitor 105 , the humidity monitor 106 , the wind speed monitor 107 and the sampling pump 133 are all electrically connected to the battery pack 103 . A roaring bird repellent 109 is also installed on the lower side of the vertical pole 101 , and the bird repellent is electrically connected to the battery pack 103 .

[0057] The solar panel 102 is a prior art, and its functionality is described here. The solar panel 102 converts light energy into electrical energy, and stores it in the battery pack 103. The battery pack 103 can provide electrical energy for the rain gauge 104, the temperature monitor 105, the humidity monitor 106, the wind speed monitor 107, the sampling pump 133, and the roaring bird repellent 109, so that basic environmental data such as rainfall information, temperature information, humidity information, and wind speed information can be collected in real time. The roaring bird repellent 109 can emit a roar to drive away birds and prevent them from staying.

[0058] At the same time, the provision of the canopy 108 can shield and protect the battery pack 103, the temperature monitor 105, the humidity monitor 106, the sampling pump 133 and the roaring bird repellent 109 from rain.

[0059] Example 2 is based on Example 1, and the following improvements are made to avoid impurities entering the water sampling process: Figures 4 to 5 As shown, each movable sampling tube 131 and each fixed sampling tube 130 are sleeved with a water collection jacket 200 on the outside, and a filter screen 201 is installed on one side of the water collection jacket 200;

[0060] By providing the water collection jacket 200 and the filter screen 201 , impurities and algae in the water can be filtered out when each movable sampling tube 131 and each fixed sampling tube 130 are sampling water.

[0061] Meanwhile, in this embodiment, in order to prevent algae and impurities in the water from clogging the filter screen 201, further improvements are made, as shown in Figures 1 to 2, a first backwash mechanism corresponding to each water intake jacket 200 located on the upper connecting rod 120 is installed at the bottom of the floating platform 100, and a second backwash mechanism corresponding to each water intake jacket 200 located on the lower connecting rod 120 is installed on the surface of the counterweight base 110;

[0062] The first backwash mechanism includes a plurality of first telescopic cylinders 210, each of which is a hollow structure. One end of each first telescopic cylinder 210 is commonly connected to a first connecting frame 211 and the other end is commonly connected to a second connecting frame 212. The first connecting frame 211 corresponds to the upper slide rail 1361 and is fixedly mounted on the upper slide rail 1361. A longitudinal telescopic rod 213 is installed at the bottom of the floating platform 100. The second connecting frame 212 corresponds to the water intake jacket 200 and is fixedly connected to the telescopic end of the longitudinal telescopic rod 213.

[0063] A first one-way water inlet valve 214 is installed at one end of each first telescopic cylinder 210 close to the upper slide rail 1361, and each first one-way water inlet valve 214 has a built-in filter. Each water intake jacket 200 located on the upper connecting rod 120 is installed with a first one-way drain valve 215. One end of each first telescopic cylinder 210 close to the water intake jacket 200 is connected to each first one-way drain valve 215 through a first hose 216.

[0064] The second backwash mechanism includes a plurality of second telescopic cylinders 220, each of which is a hollow structure. One end of each of the second telescopic cylinders 210 is commonly connected to a third connecting frame 221 and the other end is commonly connected to a fourth connecting frame 222. The third connecting frame 221 corresponds to the lower slide rail 1362 and is fixedly mounted on the lower slide rail 1362. The fourth connecting frame 222 corresponds to the water intake jacket 200 and is fixedly mounted on the counterweight base 110.

[0065] A second one-way water inlet valve 223 is installed at one end of each second telescopic cylinder 220 close to the lower sliding rail 1362, and each second one-way water inlet valve 223 has a built-in filter. Each water intake jacket 200 located on the lower connecting rod 120 is installed with a second one-way drain valve 224. One end of each second telescopic cylinder 220 close to the water intake jacket 200 is connected to each second one-way drain valve 224 through a second hose 225.

[0066] When the water surface of the pond fluctuates, the floating platform 100 will shake up and down. As mentioned above, the upper slide rail 1361 and the lower slide rail 1362 will synchronously reciprocate and move laterally, so that the first connecting frame 211 connected to the upper slide rail 1361 can reciprocate and move laterally, and the third connecting frame 221 connected to the lower slide rail 1362 can reciprocate and move laterally;

[0067] When the first connecting frame 211 reciprocates and moves laterally, since the second connecting frame 212 is fixed to the telescopic end of the longitudinal telescopic rod 213 at the bottom of the floating platform 100, each first telescopic cylinder 210 will continuously telescope, and the longitudinal telescopic rod 213 can adapt to the up and down movement of the upper slide rail 1361;

[0068] Similarly, when the third connecting frame 221 reciprocates and moves laterally, since the fourth connecting frame 222 is fixed to the counterweight base 110, each second telescopic cylinder 220 will also continuously telescope;

[0069] Since each first telescopic cylinder 210 is installed with a first one-way water inlet valve 214, pond water can enter it. The first telescopic cylinder 210 is a hollow structure, and the first telescopic cylinder 210 is connected to the first one-way drain valve 215 of the water intake jacket 200 through the first hose 216. Therefore, when each first telescopic cylinder 210 is continuously extended and retracted, the water in the first telescopic cylinder 210 will be continuously squeezed into the water intake jacket 200. Since the electric valves 1301 of each movable sampling tube 131 and each fixed sampling tube 130 are closed, the water in the water intake jacket 200 will be discharged outward through the filter screen 201, thereby backwashing and flushing away impurities and algae attached to the outside of the filter screen 201; similarly, when each second telescopic cylinder 220 is continuously extended and retracted, the water in the water intake jacket 200 will also be discharged outward from the filter screen 201, thereby backwashing and flushing away impurities and algae attached to the outside of the filter screen 201.

[0070] Furthermore, since each of the first one-way water inlet valve 214 and the second one-way water inlet valve 223 has a built-in filter, impurities and algae can be prevented from entering the water intake jacket 200;

[0071] In this way, the fluctuation of the pond water surface can be used to flush the impurities and algae outside the filter net 201 of the water intake jacket 200, so as to prevent the impurities and algae in the water from clogging the filter net 201 of the water intake jacket 200.

[0072] The above embodiments are merely illustrative of the principles and effects of the present invention, and are not intended to limit the present invention. Anyone familiar with the technology may modify or change the above embodiments without violating the spirit and scope of the present invention. Therefore, all equivalent modifications or changes made by those with ordinary knowledge in the technical field without departing from the spirit and technical ideas disclosed by the present invention should still be covered by the claims of the present invention.
