Description

Technical Field

[0001] This invention relates to the field of watershed water quality testing technology, specifically to a device and method for detecting seasonal water quality changes in plateau watersheds. Background Technology

[0002] Rivers are a key component of the Earth's hydrological cycle, and the water environment status of a river basin is an important basis for evaluating the function of a regional ecosystem, which is closely related to human life and social development. Therefore, with the development of the economy and society, the importance of river basin water environment monitoring has become increasingly prominent, as it can provide important basis for water resource management and socio-economic development decisions.

[0003] Currently, most traditional watershed water quality monitoring devices use boats to conduct sampling and testing on the watershed. While this satisfies the water quality monitoring needs of different locations, the water in the watershed has a certain degree of fluidity, making it impossible to guarantee the stability of the testing. Furthermore, when conducting water quality monitoring for different seasons, it is necessary not only to conduct water quality testing at multiple locations, but also to regularly monitor water quality changes in multiple areas. The above-mentioned testing methods lack the functions of location-based monitoring and continuous monitoring, and are also labor-intensive and inefficient. Summary of the Invention

[0004] (a) Technical problems to be solved

[0005] To address the shortcomings of existing technologies, this invention provides a device for detecting seasonal water quality changes in plateau watersheds. Water from the plateau watershed is drawn into a detection cylinder, and a water quality analyzer on the cylinder detects these changes. A height-adjustable sampling component allows for adjustment of the sample collection height to accommodate different water levels, improving the comprehensiveness of subsequent water quality change detection. The rotation of a ring-shaped transmission belt propels the sample collection mechanism, enabling detection of water quality changes in different locations. This invention solves the problem of existing detection devices typically using boats for sampling to monitor water quality changes in different locations within a watershed, thus reducing sampling efficiency.

[0016] Preferably, the propulsion mechanism includes two support members erected on both sides of the watershed and several auxiliary members for equidistant support of the middle part of the annular transmission belt;

[0017] The support includes a U-shaped fixing frame, and a transmission roller is rotatably connected to the top of the U-shaped fixing frame.

[0028] (III) Beneficial Effects

[0029] Compared with existing technologies, the present invention provides a device for detecting seasonal water quality changes in plateau watersheds, which has the following beneficial effects:

[0030] 1. This invention utilizes a water pump in the sample collection mechanism to draw water from the plateau basin into a detection cylinder. A water quality analyzer on the cylinder then performs water quality change detection. The height-adjustable collection component allows for adjustment of the sample collection height to accommodate different water levels, improving the comprehensiveness of subsequent water quality change detection. The rotation of the annular transmission belt propels the connected U-shaped mounting frame, which in turn propels the sample collection mechanism. This satisfies the need for water quality change detection in different areas of the basin, and also meets the requirements for sampling and detection at different water levels. This further enhances the functionality and effectiveness of the detection device, solving the problem that existing detection devices typically rely on boats for data collection and detection in order to monitor water quality changes at different locations within the basin, thus reducing collection and detection efficiency.

[0031] 2. This invention uses soft metal material for the metal sheet, which not only facilitates the strong adsorption of the magnet and the rapid installation of the sample bottle, but also allows for orderly transmission when the annular conveyor belt moves to the position of the transmission roller. By using irregular protrusions that are deeper than irregular holes, the irregular protrusions are easily inserted and form a raised state. When the metal sheet carrying the sample bottle moves to the position of the transmission roller, the transmission roller squeezes the irregular protrusions, causing the magnet to lose contact with the metal sheet, thus forming an automatic unloading operation.

[0032] 3. This invention uses an electric telescopic rod to drive the conical alignment cover to move up and down. The upward movement of the conical alignment cover allows the injection tube to be inserted into its interior, connecting it to the drainage tube. This facilitates the entry of the sample water from the injection tube into the sample bottle for sample collection. Conversely, the downward movement of the conical alignment cover disconnects the injection tube from the drainage tube, allowing the sample collection mechanism to move freely. This satisfies the requirements for water quality detection and sample collection. The conical shape of the alignment cover facilitates upward movement, allowing for better insertion of the injection tube and alignment with the drainage tube, thus improving the orderly nature of sample collection.

[0046] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0047] Example 1:

[0048] See attached document Figure 1-10 A seasonal water quality change detection device for plateau watersheds includes a water quality detection module for detecting water quality changes, a climate detection module for detecting seasonal changes, and a wireless communication module for remotely transmitting and receiving detection data from the water quality detection module and the climate detection module. The water quality detection module includes a sample collection unit for collecting water samples and a water quality detection unit for detecting the collected water samples. The sample collection unit includes a sample collection mechanism 100 for collecting water samples in locations with stable river flow velocity and wide river surfaces, and a propulsion mechanism 200 for moving the sample collection mechanism 100 along the river channel.

[0049] The sample collection mechanism 100 is used to detect changes in water quality in the watershed, and the propulsion mechanism 200 is used to adjust the position of the sample collection mechanism 100 to meet the needs of water quality change detection at different locations.

[0050] The sample collection mechanism 100 includes a float 110 floating on the water surface, a U-shaped mounting frame 120 fixedly connected to the top of the float 110, a water quality detection unit including a detection cylinder 130 fixed inside the U-shaped mounting frame 120, and a water quality detector 140 for detecting the internal water source installed on the detection cylinder 130. A height-adjustable collection element 160 is provided at the bottom of the float 110, and a water pump 150 for drawing water from the watershed and discharging it into the detection cylinder 130 is fixedly connected to the top of the float 110.

[0051] The water pump 150 in the sample collection mechanism 100 is used to draw water from the plateau basin into the detection cylinder 130. The water quality detector 140 on the detection cylinder 130 can then be used to detect water quality changes. The height-adjustable collection device 160 allows for easy adjustment of the sample collection height to meet the collection needs of different water levels and improve the comprehensiveness of subsequent water quality change detection.

[0052] The wireless communication module includes a wireless transceiver control box and a photovoltaic panel installed on the floating frame 110. The wireless transceiver control box adopts a control system in the prior art to electrically control the water quality detection module. The photovoltaic panel is used to absorb light energy and convert it into electrical energy to power the water quality detection module.

[0053] The propulsion mechanism 200 includes an annular drive belt 210 spanning the basin, and the top of the U-shaped mounting bracket 120 is fixedly connected to the annular drive belt 210 via a connecting bracket.

[0054] The rotation of the annular transmission belt 210 can drive the U-shaped mounting frame 120 connected to it to move forward, which in turn can drive the sample collection mechanism 100 to move forward, thus meeting the needs of water quality change detection in different locations.

[0055] This invention addresses the problem that existing detection devices typically rely on boats for data collection and testing in order to monitor water quality changes at different locations within a watershed, which reduces the efficiency of data collection and testing.

[0056] The climate detection module includes a flow velocity detection unit for detecting river flow velocity, a watershed width detection unit for detecting watershed width, a climate detection unit for detecting and recording climate and weather throughout the year and at the time of sampling, and a data acquisition unit for photographing the vegetation coverage around the watershed.

[0057] The climate monitoring module is used to regularly monitor river flow velocity, weather conditions, and vegetation coverage around the watershed on a monthly basis. The data is recorded and stored to form historical data, which provides a basis for comparison of future monitoring data changes. By monitoring river flow velocity, weather conditions, and vegetation coverage around the watershed, it is possible to better monitor seasonal water quality changes and improve the comprehensiveness of the monitoring.

[0058] See attached document Figure 4 and Figure 6 The collection device 160 includes a water pumping pipe 161 fixed inside the float 110, and a filter cylinder 163 is installed at the bottom end of the water pumping pipe 161 through a sliding frame 162, and a gravity block is installed at the bottom of the filter cylinder 163. The top end of the water pumping pipe 161 is connected to the water pump 150.

[0059] The water pumping pipe 161 is used to extract water from the watershed and discharge it into the detection cylinder 130. The water quality detector 140 is used to detect changes in water quality. The filter cylinder 163 is used to filter the extracted water.

[0060] The bottom of the floating frame 110 is fixedly connected to a guide rod frame 164, and the sliding frame 162 slides on the guide rod frame 164 in an up-and-down sliding manner. The bottom of the guide rod frame 164 is equipped with a gravity anchor block 165 by ropes.

[0061] The guide rod frame 164 is used to improve the guidance of the height adjustment of the filter cartridge 163, and the gravity anchor block 165 installed at the bottom of the guide rod frame 164 is used to further improve the stability of the sample collection mechanism 100 during operation.

[0062] See attached document Figure 4 and Figure 6 An annular float frame 166 is fixedly connected to the outer surface of the sliding frame 162. A vent pipe 167 and a drain pipe 168 are fixedly connected to the annular float frame 166. One end of the vent pipe 167 and the drain pipe 168 extend to the top of the float frame 110. The top end of the drain pipe 168 is connected to the water inlet of the water pump 150.

[0063] The annular float frame 166 is used to drive the filter cylinder 163 to float underwater and be suspended. The drain pipe 168 is used to extract and export the water inside the annular float frame 166. The vent pipe 167 is used to ensure the balance inside the annular float frame 166 and improve the balance of air and water injection.

[0064] The bottom ends of the water pumping pipe 161, the vent pipe 167 and the drain pipe 168 are all made of telescopic flexible hoses. The bottom of the annular float frame 166 is fixedly connected to the water inlet pipe, and a solenoid valve is installed on the water inlet pipe.

[0065] The bottom ends of the water pumping pipe 161, the air vent pipe 167, and the drain pipe 168 are all made of flexible hoses, which makes it easy for the water pumping pipe 161, the air vent pipe 167, and the drain pipe 168 to communicate with the inside of the annular float frame 166 without affecting the up and down adjustment of the filter cylinder 163 and the sliding frame 162.

[0066] A water inlet pipe is fixedly connected to the bottom of the annular float frame 166, and a solenoid valve is installed on the water inlet pipe. The water inlet pipe facilitates the entry of water from the watershed into the interior of the annular float frame 166. The water inside the annular float frame 166 is extracted through the drain pipe 168, thereby adjusting the buoyancy of the annular float frame 166 to meet the sampling work of substances at different heights. The solenoid valve is used to electrically control the water inlet pipe.

[0067] The outlet of the water pump 150 is fixedly connected to a three-way pipe 169, and one end of the three-way pipe 169 is connected to the inside of the detection cylinder 130. The outlets of the pumping pipe 161, the drain pipe 168, and the three-way pipe 169 are all equipped with electric switch valves.

[0068] The water pump 150 is connected to the detection cylinder 130 via a three-way pipe 169 through its outlet. This allows the water to be tested to be pumped into the detection cylinder 130 for testing. The three-way pipe 169 is used to discharge the pumped water back into the watershed. Two electric switching valves provide selective control, thereby improving the functionality and practicality of the sample collection mechanism 100.

[0069] See attached document Figure 7 and Figure 8 The propulsion mechanism 200 includes two support members erected on both sides of the watershed and several auxiliary members for equidistant support of the middle part of the annular transmission belt 210.

[0070] The two support members are used to support the annular transmission belt 210 across the watershed, ensuring the orderliness and stability of the rotation drive of the annular transmission belt 210. By installing several equidistant auxiliary members in the middle of the annular transmission belt 210, the stability of the annular transmission belt 210 during operation is further improved, as is the stability of the sample collection mechanism 100.

[0071] The support includes a U-shaped fixing frame 220, and a transmission roller 230 is rotatably connected to the top of the U-shaped fixing frame 220. The transmission rollers 230 in the two support members are connected by a ring transmission belt 210. A rotating component for rotating one of the transmission rollers 230 is installed on one or both of the U-shaped fixing frames 220, and the rotating component includes a rotating handle or a motor.

[0072] The rotating component is used to rotate one of the transmission rollers 230. The transmission rollers 230 in the two support components are connected by an annular transmission belt 210. The rotation of one transmission roller 230 can drive the annular transmission belt 210 to move in a ring through the other transmission roller 230, which in turn can drive the sample collection mechanism 100 connected to it to move forward, forming a large-scale water quality change detection operation.

[0073] The rotating components, including a rotating handle or an electric motor, allow for easy selection of the rotation drive method according to actual needs.

[0074] See attached document Figure 7The auxiliary components include an L-shaped anchor rod 240 fixed to the bottom of the river basin, and a support auxiliary roller 250 is rotatably connected to the top of the L-shaped anchor rod 240, and the support auxiliary roller 250 is in contact with the inner side of the annular transmission belt 210.

[0075] The L-shaped anchor bolts 240 and the support auxiliary rollers 250 are used to support the middle part of the annular transmission belt 210 that spans the watershed, thereby improving the stability of the annular transmission belt 210 during its advancement.

[0076] See attached document Figure 4 , Figure 5 and Figures 7 to 10 A number of sample collection mechanisms 300 are provided on the annular transmission belt 210. The sample collection mechanism 300 is connected to the outlet of the water pump 150. The sample collection mechanism 300 includes a number of sample bottles 310 that are detachably installed on the annular transmission belt 210 and a collection component 320 installed on the U-shaped mounting frame 120.

[0077] The sample collection mechanism 300 includes several detachable sample bottles 310 mounted on the annular transmission belt 210, which facilitates the collection component 320 mounted on the U-shaped mounting frame 120 to discharge samples from different locations into the sample bottles 310 at different locations, thus forming a water quality collection and storage operation at different locations. This facilitates subsequent in-depth research and analysis of water quality changes at different locations by staff.

[0078] See attached document Figure 1-10 A detection method for a seasonal water quality change detection device in a plateau watershed includes the following steps:

[0079] S1. The climate detection module is used to detect river flow velocity, weather conditions, and vegetation coverage around the watershed on a monthly basis, and the data is recorded and stored.

[0080] S2. The water sources in the watershed are collected and tested regularly through the sample collection unit and water quality testing unit in the water quality testing module;

[0081] S21. Water from the basin is pumped out by a water pump 150 installed on the float 110 and discharged into the detection cylinder 130 in the water quality detection unit. Water quality changes are detected by a water quality detector 140 on the detection cylinder 130.

[0082] S22. The height of the sampling device 160 is adjusted by the water pump 150 to form water source sampling and detection work at different depths;

[0083] S23. The propulsion mechanism 200 in the sample collection unit propels the floating platform 110 on the surface of the watershed to form a water quality change detection work in different areas;

[0084] S3. The detection data from the climate monitoring module and the water quality change data from the water quality monitoring module are remotely transmitted to the central monitoring platform for analysis and control via the wireless communication module.

[0085] Example 2: The difference from Example 1 is that;

[0086] See attached document Figures 8 to 10 A magnet block 311 is fixedly connected to the top of the sample bottle 310. Several metal plates 312 are fixedly connected to the annular transmission belt 210, and each of the metal plates 312 has an irregular hole. An irregular protrusion 313 for inserting into the irregular hole is fixedly connected to the top of the magnet block 311. An injection tube 314 and an L-shaped gas guide tube 315 are fixedly connected to the sealing cap at the bottom opening of the sample bottle 310. A one-way valve is installed on the injection tube 314, and a sealing sleeve is fixedly connected to the bottom end of the injection tube 314. A pressure valve is installed at the bottom end of the L-shaped gas guide tube 315.

[0087] The collection component 320 is used to discharge the water collected by the sample collection mechanism 100 into the sample bottle 310 through the injection pipe 314, thus forming a sample collection operation. The L-shaped gas guide pipe 315 is used to export the gas inside the sample bottle 310, thereby improving the smoothness of sample injection.

[0088] The metal sheet 312 is made of soft metal material in the prior art; the irregular protrusion 313 is deeper than the irregular hole, so that the irregular protrusion 313 can form a protruding state after insertion; the U-shaped mounting bracket 120 is fixedly connected to the upper layer of the annular transmission belt 210, and several metal sheets 312 are installed at equal intervals on the lower layer of the annular transmission belt 210, so that when the annular transmission belt 210 drives the sample collection mechanism 100 to move forward, its sample collection mechanism 300 can move in the opposite direction, which makes it convenient for staff to take out the sample bottle 310 with the collected sample in an orderly manner;

[0089] By using soft metal material for the metal sheet 312, it is not only easy for the magnet 311 to strongly attract and form the sample bottle 310 for quick installation, but also allows for orderly transmission when the annular transmission belt 210 moves to the position of the transmission roller 230. The irregular protrusion 313 is larger than the depth of the irregular hole, so that the irregular protrusion 313 forms a protruding state after insertion. When the metal sheet 312 carrying the sample bottle 310 moves to the position of the transmission roller 230, the transmission roller 230 squeezes the protruding irregular protrusion 313, so that the magnet 311 loses contact with the metal sheet 312, thus forming an automatic unloading operation.

[0090] The pressure valve includes a vent cylinder 316 fixedly connected to the bottom end of the L-shaped vent pipe 315, and a sealing block 317 for blocking the L-shaped vent pipe 315 is slidably connected inside the vent cylinder 316. A spring 318 for elastically compressing the sealing block 317 is provided inside the vent cylinder 316.

[0091] The ventilation tube 316 is used to exhaust the gas inside the L-shaped ventilation tube 315. The spring 318 elastically squeezes the sealing block 317, causing the sealing block 317 to block the L-shaped ventilation tube 315. This ensures that when there is no pressure, the gas or sample inside the sample bottle 310 will not be exhausted through the L-shaped ventilation tube 315, thereby improving the sample storage effect.

[0092] Example 3: The difference from Example 1 is that;

[0093] See attached document Figure 4 , Figure 5 and Figure 9 The collection component 320 includes an electric telescopic rod 321 fixed on a U-shaped mounting bracket 120. The telescopic end of the electric telescopic rod 321 is fixedly connected to a conical alignment cover 322 via a bracket. The bottom of the conical alignment cover 322 is fixedly connected to a drainage pipe 323, and the bottom end of the drainage pipe 323 is connected to the inside of the detection cylinder 130 or the outlet of the water pump 150.

[0094] The electric telescopic rod 321 is connected to the wireless transceiver control box installed on the floating frame 110 to drive the conical alignment cover 322 to move up and down. By moving the conical alignment cover 322 upward, the injection tube 314 can be inserted into the inside of the conical alignment cover 322, so that the injection tube 314 is connected to the drainage tube 323, thereby facilitating the sample water inside the injection tube 314 to enter the sample bottle 310 to form a sample collection.

[0095] Conversely, by moving the cone-shaped aiming cover 322 downwards, the injection tube 314 and the drainage tube 323 can be disconnected, which facilitates the advancement of the sample collection mechanism 100 to meet the requirements of water quality detection and water sample collection.

[0096] The cone-shaped alignment cover 322 facilitates upward movement, allowing the injection tube 314 to be better inserted and aligned with the drainage tube 323, thus improving the orderly collection of samples.

[0097] It should be noted that the term "comprising" or any other variation thereof is intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus. Without further limitation, an element defined by the phrase "comprising one..." does not exclude the presence of other identical elements in the process, method, article, or apparatus that includes said element.

[0098] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
