Description

Technical Field

[0001] The present invention belongs to the technical field of agricultural monitoring, and particularly 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 production. In agricultural meteorological monitoring, it is usually necessary to monitor basic meteorological information such as environmental temperature and humidity, rainfall, etc. However, in fisheries-related monitoring, not only basic meteorological information needs to be monitored, but also sampling and analysis of pond water bodies are required.

[0003] In fisheries-related monitoring, the common means in the prior art is to install a counterweight base at the bottom of the pond, connect a floating platform through a telescopic connecting rod, make the floating platform float on the pond water surface, and install 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 a plurality of equally spaced sampling tubes along the telescopic connecting rod to collect water bodies in layers.

[0004] However, through analysis, it is found that during seasonal changes, the water surface of the pond will rise or fall, and each sampling tube will not be able to adaptively adjust to an equally spaced arrangement according to the change in the water surface height, which is not conducive to the layered sampling of the pond water body.

Specific implementation mode

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

[0036] Embodiment 1, as Figures 1 to 3 shown in an agricultural meteorological monitoring station, including 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 chute is arranged inside the lower connecting rod 121. A sliding rod 122 that is slidably connected to the chute 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 at the bottom of the pond, the upper connecting rod 120 and the chute of the lower connecting rod 121 form a telescopic structure through the sliding rod 122. Therefore, 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 jointly arranged between the upper connecting rod 120 and the lower connecting rod 121. The water sampling mechanism includes two fixed sampling tubes 130 and multiple movable sampling tubes 131. Electric valves 1301 are installed on each of the fixed sampling tubes 130 and each of the movable sampling tubes 131. Two fixed blocks 1302 are installed on the two fixed sampling tubes 130, and the two fixed blocks 1302 are respectively fixedly installed at 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. Longitudinal positioning sliding rails 132 are opened on both the upper connecting rod 120 and the lower connecting rod 121. Each movable block 1311 located on the upper connecting rod 120 is slidably connected to the longitudinal positioning sliding 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 sliding rail 132 of the lower connecting rod 121;

[0040] As Figures 1 to 3 shown, the fixed sampling tubes 130 and the provided movable sampling tubes 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 the water bodies at multiple depths in the pond;

[0041] At the same time, as Figures 1 to 3 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. Thus, 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 known above, the movable sampling tube 131 is slidably connected to the longitudinal positioning sliding 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 longitudinally slide with respect to the upper connecting rod 120 and the lower connecting rod 121 respectively.

[0042] Equal distances are set between 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. 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 by a first telescopic corrugated tube 1331. A sampling pump 134 is installed on the surface of the floating platform 100. The movable sampling tube 131 at the uppermost side of the upper connecting rod 120 is connected to the sampling pump 133 through a second telescopic corrugated tube 1332. A drain pipe 1341 is also arranged at the output end of the sampling pump 133;

[0043] As Figures 1 to 3As shown in the figure, the spaces between two adjacent active sampling tubes 131, between the fixed sampling tube 130 and the nearest active sampling tube 131, and between two adjacent fixed sampling tubes 130 are all set at equal distances. Therefore, the equal-distance positions of each active sampling tube 131 and each fixed sampling tube 130 underwater in the pond are ensured. At the same time, the telescopic connection between the sampling tubes is ensured by the first telescopic corrugated tube 1331, and the telescopic connection between the uppermost active sampling tube 131 and the sampling pump 133 is ensured by the second telescopic corrugated tube 1332.

[0044] A spacing adjustment mechanism is also jointly 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 nearest active sampling tube 131. The first hinge seats 1351 are installed on both fixed blocks 1302 and each active block 1311. The second hinge seats 1352 are arranged at the middle positions between two adjacent first hinge seats 132. Two hinge rods 1353 are jointly hinged between two adjacent first hinge seats 1351 and the second hinge seat 1352 therebetween 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. The remaining second hinge seats 1352 on the upper and lower sides are respectively slidably connected to the upper slide rail 1361 and the lower slide rail 1362. The counterweight base 110 is provided with a horizontal positioning slide rail 137, and the lower end of the lower slide rail 1362 is provided with a positioning slider 1363 that matches the horizontal positioning slide rail 137.

[0046] A horizontal positioning rod 1381 is also erected on the fixed block 1302 located on the upper connecting rod 120. The horizontal positioning rod 1381 is in the middle position between 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 horizontal positioning rod 1381 horizontally penetrates through the positioning block 1382.

[0047] As Figures 1 to 3 shown, Figures 1 to 3 As shown in the figure, it floats on the pond water surface through the floating platform 100, so that the extension length 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 of the pond drops, the height of the floating platform 100 decreases as the water level drops. Therefore, the fixed block 1302 fixed to the upper connecting rod 120 will move downward and approach the fixed block 1302 fixed to the lower connecting rod 121. Since the positioning block 1382 is disposed on the second hinge seat 1352 corresponding to the two fixed blocks 1302, and the second hinge seat 1352 is fixed to the upper slide rail 1361, and the lateral positioning rod 1381 horizontally penetrates through the positioning block 1382, the upper connecting rod 120 will descend synchronously with the upper slide rail 1361. The upper slide rail 1361 moves downward relative to the lower slide rail 1362. In this way, the first hinge seat 1351 corresponding to the two fixed blocks 1302 drives the second hinge seat 1352 fixed to the upper slide rail 1361 to drive the upper slide rail 1361 and the lower slide rail 1362 to move horizontally away from the upper connecting rod 120 synchronously through the transmission of the hinge rod 1353. The positioning slider 1363 of the lower slide rail 1362 slides horizontally along the lateral positioning slide rail 137;

[0049] During this process, the remaining second hinge seats 1352 corresponding to the upper connecting rod 120 and the lower connecting rod 120 will slide downward relative to the upper slide rail 1361 and the lower slide rail 1362 respectively. And through the V-shaped hinge structure composed of two adjacent first hinge seats 1351, second hinge seats 1352 and two hinge rods 1353, the distances between two adjacent movable sampling tubes 131, between the fixed sampling tube 130 and the nearest movable sampling tube 131, and between two adjacent fixed sampling tubes 130 are synchronously reduced and remain equidistant. In this way, when the water level of the pond drops in the dry season and the total height of the upper connecting rod 120 and the lower connecting rod 121 decreases, the sampling tubes can be evenly distributed at equal distances, enabling the pond to sample evenly at equal distances during water body sampling;

[0050] Similarly, when the water level of the pond rises, the height of the floating platform 100 increases as the water level rises. The upper connecting rod 120 will rise synchronously with the upper slide rail 1361. The two fixed blocks 1302 move away. And the remaining second hinge 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 hinge structure composed of two adjacent first hinge seats 1351, second hinge seats 1352 and two hinge rods 1353, the distances between two adjacent movable sampling tubes 131, between the fixed sampling tube 130 and the nearest movable sampling tube 131, and between two adjacent fixed sampling tubes 130 are synchronously increased and remain equidistant. 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 at equal distances, enabling the pond to sample evenly at equal distances during water body sampling.

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

[0052] ① Install the counterweight base 110 at the bottom of the pond. It floats on the pond surface through the floating platform 100. The counterweight base 110 and the floating platform 100 are slidably connected through the upper connecting rod 120 and the lower connecting rod 121, enabling it to adapt to the water surface height automatically.

[0053] ② The meteorological monitoring component of the floating platform can monitor the environmental data of the pond. At the same time, it can use the water body sampling mechanism to conduct stratified sampling of the pond water body. And through the setting of the spacing adjustment mechanism, when the pond water surface rises or falls, each sampling tube of the water body sampling mechanism can always be equidistantly distributed in the water body. Specifically, depth locators can be installed on each sampling tube. When sampling, it is single-depth sampling. Open the electric valve 1301 corresponding to the sampling depth, close all the other electric valves 1301, and pump the water at this depth into the sampling pump 134 and discharge it through the drain pipe 1341 for collection.

[0054] As a further description of the meteorological monitoring component in this embodiment, as Figure 1 shown, a vertical rod 101 is installed on the surface of the floating platform 100. 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] Among them, the solar panel 102, the rain gauge 104, and the wind speed detector 107 are all installed on the upper side of the vertical rod 101. A rain shelter 108 is also provided in the middle of the vertical rod 101. The temperature monitor 105 and the humidity monitor 106 are installed on the lower side of the vertical rod 101.

[0056] The battery pack 103 is electrically connected to the solar panel 102. 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 repeller 109 is also installed on the lower side of the vertical rod 101, and it is electrically connected to the battery pack 103.

[0057] The solar panel 102 is a prior art. Here, a functional description is made. The solar panel 102 converts light energy into electrical energy and stores it in the battery pack 103. Through the battery pack 103, electrical energy can be provided 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 repeller 109. In this way, basic environmental data such as rainfall information, temperature information, humidity information, and wind speed information can be collected in real time. The set roaring bird repeller 109 can emit a roar to drive away birds and prevent them from staying.

[0058] Meanwhile, the setting 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 booming bird repeller 109 from rain.

[0059] Embodiment 2 is an improvement based on Embodiment 1 to prevent impurities from entering during the water quality sampling process, as follows. Figures 4 to 5 As shown, a water intake sleeve 200 is sleeved outside each movable sampling tube 131 and each fixed sampling tube 130, and a filter screen 201 is installed on one side of the water intake sleeve 200.

[0060] By setting the water intake sleeve 200 and the filter screen 201, when water sampling is carried out on each movable sampling tube 131 and each fixed sampling tube 130, impurities and algae in the water can be filtered out.

[0061] Meanwhile, in this embodiment, to prevent the filter screen 201 from being blocked by algae and impurities in the water, a further improvement is made. As shown in the figures, a first backwashing mechanism corresponding to each water intake sleeve 200 located on the upper connecting rod 120 is installed at the bottom of the floating platform 100, and a second backwashing mechanism corresponding to each water intake sleeve 200 located on the lower connecting rod 120 is installed on the surface of the counterweight base 110.

[0062] The first backwashing mechanism includes a plurality of first telescopic cylinders 210. The interior of each first telescopic cylinder 210 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 installed 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 sleeve 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. Each first one-way water inlet valve 214 is internally provided with a filter screen. A first one-way water drainage valve 215 is installed on each water intake sleeve 200 located on the upper connecting rod 120. One end of each first telescopic cylinder 210 close to the water intake sleeve 200 is connected to each first one-way water drainage valve 215 through a first hose 216.

[0064] The second backwashing mechanism includes a plurality of second telescopic cylinders 220. The interior of each second telescopic cylinder 220 is a hollow structure. One end of each second telescopic cylinder 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 installed on the lower slide rail 1362. The fourth connecting frame 222 corresponds to the water intake sleeve 200 and is fixedly installed 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 slide rail 1362. Each second one-way water inlet valve 223 is internally provided with a filter screen. A second one-way drain valve 224 is installed on each water intake sleeve 200 located on the lower connecting rod 120. One end of each second telescopic cylinder 220 close to the water intake sleeve 200 is communicated with each second one-way drain valve 224 through a second hose 225 respectively.

[0066] When the water surface of the pond fluctuates, the floating platform 100 will shake up and down. As described above, the upper slide rail 1361 and the lower slide rail 1362 will perform synchronous reciprocating lateral movements. In this way, the first connecting frame 211 connected to the upper slide rail 1361 can perform reciprocating lateral movements, and the third connecting frame 221 connected to the lower slide rail 1362 can perform reciprocating lateral movements;

[0067] When the first connecting frame 211 performs reciprocating lateral movements, 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 expand and contract, 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 performs reciprocating lateral movements, since the fourth connecting frame 222 is fixed to the counterweight base 110, each second telescopic cylinder 220 will also continuously expand and contract;

[0069] Since each first telescopic cylinder 210 is equipped with a first one-way water inlet valve 214 to allow the water in the pond to enter it, the first telescopic cylinder 210 is a hollow structure, and the first telescopic cylinder 210 is communicated with the first one-way drain valve 215 of the water intake sleeve 200 through a first hose 216. Therefore, when each first telescopic cylinder 210 continuously expands and contracts, the water in the first telescopic cylinder 210 will be continuously squeezed into the water intake sleeve 200. Since the electric valves 1301 of each movable sampling pipe 131 and each fixed sampling pipe 130 are closed, the water in the water intake sleeve 200 will be discharged outward through the filter screen 201, so as to backwash and wash away the impurities and algae attached to the outside of the filter screen 201; Similarly, when each second telescopic cylinder 220 continuously expands and contracts, the water in the water intake sleeve 200 will also be discharged outward through the filter screen 201, so as to backwash and wash away the impurities and algae attached to the outside of the filter screen 201.

[0070] And since each first one-way water inlet valve 214 and second one-way water inlet valve 223 are internally provided with filter screens, impurities and algae can be prevented from entering the interior of the water intake sleeve 200;

[0071] In this way, the fluctuations of the pond water surface can be utilized to wash the impurities and algae on the outside of the filter screen 201 of the water intake sleeve 200, so as to prevent the impurities and algae in the water body from clogging the filter screen 201 of the water intake sleeve 200.

[0072] The above embodiments are only used to exemplarily illustrate the principles and effects of the present invention, rather than to limit the present invention. Any person familiar with this technology can modify or change the above embodiments without departing from the spirit and scope of the present invention. Therefore, all equivalent modifications or changes completed 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.
