Description

Technical Field

[0001] This invention relates to the field of hydrological monitoring equipment technology, specifically a fully automatic water and sediment collection and monitoring device. Background Technology

[0002] A lead weight is a specialized hydrological surveying instrument cast from lead or a lead-iron mixture. Its streamlined body is equipped with a suspension mechanism, a current meter suspension rod, and longitudinal and transverse tail structures. Its own weight stabilizes the equipment at a predetermined water depth using a flexible cable, enabling depth and velocity measurements as well as sediment sampling. A balance must be struck between weight selection and fluid resistance: too light a weight increases cable deflection, affecting accuracy; too heavy a weight increases equipment load. Modern products range from 8 to 500 kg, conform to national standards, and are widely used in cableway surveying systems for rivers and lakes.

[0003] Chinese patent discloses a sampling and detection device for sediment content in water flow during water conservancy surveys (authorization announcement number CN115575280B). The patent includes a main body, inside which is fixedly installed an electric telescopic rod with its output end pointing downwards. A lifting frame is fixed to the end of the output end of the electric telescopic rod.

[0004] Currently, most methods for detecting sediment content involve first collecting and weighing a water sample, then separating the water sample from the sand, drying the sand, weighing it again, and finally determining the sediment content based on the weight percentage of sand in the overall water sample. However, this method has significant shortcomings; it is not only inconvenient to operate but also inefficient. While the aforementioned patent can separate water and sand from the sample and dry the sand, sand easily adheres to the water sample container and the inner wall of the water pipe, causing deviations in the measured sand weight and reducing the accuracy of sediment content detection. Furthermore, the aforementioned patent cannot achieve automatic monitoring of sediment content. Therefore, we propose a fully automatic water and sediment collection and monitoring device.

[0040] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0041] Example 1: Please refer to Figures 1 to 10In this embodiment of the invention, a fully automatic water and sediment collection and monitoring device includes a water body detection device 1. The water body detection device 1 includes a lead weight shell 101. A lifting ring 102 for lifting and moving the lead weight shell 101 is fixedly connected to the upper side wall of the lead weight shell 101. When monitoring water, the water body detection device 1 needs to be moved by a matching lifting platform. The lifting platform can be a cable car structure, which is well known to those skilled in the art and will not be described in detail here. A pumping assembly 2 for sampling is fixedly connected to the lower side wall of the lead weight shell 101. The pumping assembly 2 includes a bottom shell 201 welded and fixedly connected to the lower side wall of the lead weight shell 101. The lower end of the bottom shell 201 is threadedly connected to... The water sample cylinder 202 and the bottom shell 201 have matching threaded interfaces, facilitating the disassembly and removal of the water sample cylinder 202 containing the water sample. The bottom shell 201 contains a C-shaped extraction pipe 203, with both ends penetrating the bottom of the bottom shell 201 to extract water from below the lead fish shell 101 and discharge it from the other end. A main valve shell 204 is connected to and fixed to the extraction pipe 203. A sampling valve core 205 is rotatably connected inside the main valve shell 204. The sampling valve core 205 has a sampling valve hole 206 that communicates with the extraction pipe 203. When the extraction pipe 203 transports water samples, a sampling valve hole 206 is formed. Rotating the sample valve core 205 by 90 degrees allows a portion of the water sample to be extracted from the sampling valve orifice 206. Simultaneously, the water sample, under gravity, is discharged into the detachable cylinder 303 through the discharge pipe 207. The lower end of the main valve housing 204 is connected to and fixed with the discharge pipe 207 for discharging water samples. A water pump 208 located on one side of the main valve housing 204 is connected to the extraction pipe 203. When the water pump 208 is started, it allows water to flow within the extraction pipe 203. A first motor 209 for driving the sampling valve core 205 to rotate is fixedly connected to the front wall of the main valve housing 204, and the output end of the first motor 209 is fixedly connected to the sampling valve core 205. The upper end of the main valve housing 204 is connected to a drying unit for drying sand. Component 4, the drying assembly 4 includes a hot air blower 401 for generating hot air, a duct 402 connected to the upper side wall of the hot air blower 401, and two air inlet pipes 403 connected to the side wall of the air duct 402 to communicate with the outside air. When the hot air blower 401 is started, outside air enters the air duct 402 through the air inlet pipes 403. After the air passes through the hot air blower 401, it generates hot air. The hot air dries the sand through the sampling valve hole 206 and the discharge pipe 207. At the same time, the sand inside the sampling valve hole 206 and the discharge pipe 207 is also blown out by the hot air. The upper ends of the two air inlet pipes 403 penetrate the upper side wall of the lead fish shell 101. A cleaning assembly 6 is fixedly connected to the exhaust pipe 203.

[0042] The drying assembly 4 also includes a horizontal plate 404 welded and fixedly connected to the rear side wall of the hot air blower 401. A switch button 405 electrically connected to the hot air blower 401 is fixedly connected to the lower side wall of the horizontal plate 404. When the hot air blower 401 is pressed, the power of the hot air blower 401 can be turned on directly. When the hot air blower 401 is not pressed, the power of the hot air blower 401 can be turned off. A cam 407 is fixedly connected to the rear side wall of the sampling valve core 205 through a rotating rod 406. The rotating rod 406 is rotatably connected to the main valve shell 204. When the sampling valve core 205 rotates 90 degrees, the cam 407 will also rotate 90 degrees through the rotating rod 406, so that its protruding part just pushes the switch button 405, causing the hot air blower 401 to turn on the power. Two exhaust pipes 408 connected to the bottom shell 201 are inserted between the upper and lower side walls of the lead fish shell 101. The hot air generated by the hot air blower 401 is finally discharged through the exhaust pipes 408.

[0043] A weighing assembly 3 for weighing water samples is fixedly connected to the lower side wall of the lead fish shell 101. The weighing assembly 3 includes an electronic hanging scale 301 for weighing, which consists of a weighing sensor and a hanging rod. The fixed cylinder 302 is mounted on the hanging rod via a telescopic frame assembly 5. When the detachable cylinder 303 contains a water sample, the total weight of the structure is measured by the weighing sensor via the hanging rod. By subtracting the weight of components such as the telescopic frame assembly 5 and the detachable cylinder 303, the total weight of the water sample can be obtained. The structure and principle of the electronic hanging scale 301 are existing technologies and will not be described in detail here. The electronic crane scale 301 is fixedly connected to a fixed cylinder 302 via a telescopic frame assembly 5. A detachable cylinder 303 is threadedly connected to the lower end of the fixed cylinder 302, allowing the detachable cylinder 303 to be disassembled from the fixed cylinder 302 to help workers remove sand. A solenoid valve 304 is installed at the lower end of the detachable cylinder 303 to open or close the opening of the detachable cylinder 303. The solenoid valve 304 is powered by a battery inside the lead weight housing 101 via a power cord. The battery and power cord are not shown in the figure. A filter screen 305 for filtering sand is fixedly connected inside the detachable cylinder 303.

[0044] The telescopic frame assembly 5 includes an upper hanger 501 fixedly connected to the boom of the electronic crane scale 301. A lower hanger 502 fixedly connected to the fixed cylinder 302 is located below the upper hanger 501. Multiple insert rods 503 are fixedly connected to the upper end of the lower hanger 502 by welding. Multiple sliders 504 are slidably connected inside a cavity carved at the lower end of the upper hanger 501, and the insert rods 503 and sliders 504 are fixedly connected to achieve the up-and-down movement of the lower hanger 502. Mounting plates 505 are fixedly connected to opposite ends of both the upper and lower hangers 501 and 502, and the two mounting plates 505 are positioned vertically. An electric... Magnet 506, when electromagnet 506 is activated, can attract the lower electromagnet 506 to move upward. Electromagnet 506 is powered by a power cord. The battery and power cord are not shown in the figure. An annular plate 507 is fixedly connected inside the fixed cylinder 302. A sealing plate 508 with a diameter larger than the inner diameter of the annular plate 507 is fixedly connected to the sampling tube 207. When electromagnet 506 is activated, it can magnetically attract the mounting plate 505 to move the lower hanger 502 upward. The lower hanger 502 moves the fixed cylinder 302 upward, so that the annular plate 507 and the sealing plate 508 abut against each other, thereby effectively preventing the sand from being blown out by hot air during drying.

[0045] Example 2: Please refer to Figure 4 and Figure 7 Based on Embodiment 1, the cleaning component 6 includes a cleaning valve housing 601 connected to the extraction pipe 203. A cleaning valve core 602 is rotatably connected inside the cleaning valve housing 601. An L-shaped valve hole is drilled inside the cleaning valve core 602. When the cleaning valve core 602 rotates 90 degrees, it connects the extraction pipe 203 to the flushing pipe 603. After the test is completed, the water pump 208 can draw pure water from the water tank 604 through the extraction pipe 203 and the flushing pipe 603, thereby flushing the extraction pipe 203 and the water pump 208. The upper end of the cleaning valve housing 601 is connected to the flushing pipe 603. The water tank 604 is fixedly connected to the inner wall of the lead fish housing 101. The upper end of the housing 101 is also equipped with a water inlet that communicates with the water tank 604. A sealing cap is installed on the upper end of the water inlet. During operation, the water inlet is sealed by the sealing cap to prevent the water inside the water tank 604 from being contaminated. In addition, the sealing cap is also equipped with a one-way valve to allow outside air to enter and prevent it from affecting the normal drainage of the water tank 604. The water inlet and the sealing cap are not shown in the figure. The structure and working principle of the water inlet and the sealing cap are common knowledge to those skilled in the art and will not be described in detail here. The flushing pipe 603 is connected to the bottom of the water tank 604. A second motor 605 is fixedly connected to the front side wall of the cleaning valve housing 601, and the output end of the second motor 605 is fixedly connected to the cleaning valve core 602.

[0046] A protective component 7 located on one side of the water pump 208 is connected to the drain pipe 203. The protective component 7 includes a negative pressure cylinder 701 connected to the drain pipe 203. A magnetic plug 702 is slidably connected inside the negative pressure cylinder 701. A reset spring 703 for resetting the magnetic plug 702 is fixedly connected between the magnetic plug 702 and the lower inner wall of the negative pressure cylinder 701. A magnetic switch 704 electrically connected to the water pump 208 is fixedly connected to the side wall of the negative pressure cylinder 701. When the magnetic switch 704 senses the magnetic force, it will turn off the water pump 208.

[0047] The working principle of this invention is:

[0048] In use, the present invention firstly involves the staff hoisting the water body detection device 1 to the monitoring area using a lifting platform. The water body detection device 1 floats on the water surface due to its own buoyancy. When sampling is required, the water pump 208 is remotely activated, causing the water pump 208 to draw water samples through the extraction pipe 203. The water enters from one end of the extraction pipe 203 and exits from the other end. During this process, the first motor 209 is activated, which drives the sampling valve core 205 to rotate 90 degrees, causing the sampling valve hole 206 to take out a portion of the water sample. At the same time, the water sample is discharged into the detachable cylinder 303 through the discharge pipe 207 under the action of gravity. Meanwhile, the sand in the water sample is filtered and intercepted by the filter screen 305.

[0049] Meanwhile, due to the rotation of the sampling valve core 205, the water pump 208 can no longer draw water, which causes negative pressure to be generated inside the negative pressure cylinder 701, driving the magnetic plug 702 to move down. Finally, the magnetic switch 704 senses the magnetic force of the magnetic plug 702, thereby turning off the switch of the water pump 208, which protects the water pump 208 and automatically shuts it down.

[0050] After the sampling valve core 205 rotates 90 degrees, the cam 407 also rotates 90 degrees via the rotating rod 406, causing its protruding part to actuate the switch button 405, thereby turning on the power to the hot air blower 401. At this time, the hot air blower 401 generates hot air, blowing the sand adhering to the sampling valve hole 206 and the inner wall of the discharge tube 207 into the detachable cylinder 303. After these steps are completed, the first motor 209 will start again, driving the sampling valve core 205 to rotate 45 degrees. This angle can prevent the discharge tube from being drawn in. The water and sand in 203 re-enter the sampling valve hole 206, and at the same time, the sampling valve core 205 drives the cam 407 to rotate 45 degrees through the rotating rod 406. The switch button 405 is no longer pushed. At this time, the power of the air duct 402 is turned off. At this time, the total weight of the water sample is measured by the electronic crane scale 301. After the measurement is completed, the solenoid valve 304 is activated to drain part of the water in the detachable cylinder 303 into the water sample cylinder 202. Afterwards, the staff can unscrew the water sample cylinder 202 to take out the water sample.

[0051] Subsequently, the first motor 209 again sampled the valve core 205, which drove the cam 407 to reset and rotate 45 degrees. At this time, the cam 407 pushed the switch button 405 again, so that the air duct 402 could be restarted to dry the sand above the filter screen 305 with hot air. During this process, outside air entered the air duct 402 through the air inlet pipe 403. After passing through the hot air blower 401, the air generated hot air. The hot air dried the sand through the sampling valve hole 206 and the discharge pipe 207.

[0052] At the same time, the electromagnet 506 will also be activated, thereby magnetically attracting the lower electromagnet 506 to move upward. When the electromagnet 506 is activated, it can drive the lower hanger 502 to move upward through the magnetic attraction of the mounting plate 505. The lower hanger 502 drives the fixed cylinder 302 to move upward, so that the annular plate 507 and the sealing plate 508 abut against each other, thereby effectively preventing the sand from being blown out by the hot air during drying. The hot air generated by the hot air blower 401 will eventually be discharged through the exhaust pipe 408. After drying, the weight of the sand will be measured, and the sand content will be determined by the weight ratio of sand to total water sample.

[0053] After the measurement is completed, the second motor 605 drives the cleaning valve core 602 to rotate 90 degrees, so that the suction pipe 203 is connected to the flushing pipe 603, and the water pump 208 can draw pure water from the water tank 604 through the suction pipe 203 and the flushing pipe 603, thereby flushing the suction pipe 203 and the water pump 208 and preventing the sand in the suction pipe 203 from affecting the next measurement result.

[0054] In addition, the lead fish shell 101 of this application can be equipped with various sensors and used in conjunction with the transfer of the lifting platform to monitor the water conditions at different locations. The sensors can be flow rate sensors, turbidity sensors, etc., which are existing technologies and will not be described again.

[0055] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
