Description

Technical Field

[0001] The present invention relates to the technical field of water pollution monitoring, and in particular to a water conservancy intelligent monitoring device and a method of using the same. Background Art

[0002] With the rapid development of industrialization and urbanization, the pollution and shortage of water resources are becoming increasingly serious, and higher requirements are placed on the water monitoring of important water sources such as reservoirs. Traditional monitoring methods rely on manual sampling and laboratory analysis, which is not only time-consuming and labor-intensive, but also difficult to achieve continuous and real-time monitoring. The existing monitoring methods still have corresponding problems, such as a water conservancy monitoring device for a water conservancy project in Publication No. CN115683748A. When in use, the measuring rope is released so that the measuring rope moves downward under the gravity of the counterweight. When the collecting piece contacts the bottom of the water, the silt on the bottom of the water will push the collecting piece to move upward. When the circular hole on the collecting piece is aligned with the circular hole on the counterweight, the water in the bottom of the water can enter the collecting piece, and the collecting piece can sample the water. After the sampling is completed, the measuring rope is reeled in and measured. The measuring rope causes the counterweight and the collecting piece to move upward, and then people use monitoring tools to monitor the water in the collection. At the same time, by observing the installation piece aligned with the scale on the tape measure, they know the length of the measuring rope that has been released, and then they can confirm the depth of the sampled water. However, the collecting piece can only take samples when it is in contact with the bottom of the water, resulting in only being able to detect the water body at the bottom of the water, and unable to monitor the bottom of the water at different depths. In addition, when it is necessary to monitor the flow rate, flow rate and impact force of the water body, this type of monitoring device cannot be used. It has poor applicability and a single function and cannot meet the monitoring needs. In addition, when the collecting piece is sampling at the bottom of the water, if the water body silt and algae block the water inlet, the collecting piece needs to be recovered above the water surface and cleaned manually. Not only will the sampling fail, but it will also affect the monitoring efficiency. Summary of the Invention

When the screw stops moving, the slide opens the drain cylinder, allowing the water to enter the interior of the monitor through the water inlet cylinder. At this time, the water hits and drives the impeller to move and rotate.

[0029] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0030] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as limiting the present invention.

[0031] Reference Figure 1 - Figure 9 As shown, a water conservancy intelligent monitoring device includes a fixed base 1 and a sliding frame 11. The sliding frame 11 is slidably mounted above the fixed base 1. A telescopic assembly is movably mounted on the side wall of the sliding frame 11. The telescopic assembly includes a second pulley 123 and a screw 21. The second pulley 123 is rotatably mounted on the side wall of the sliding frame 11. The screw 21 passes through the sliding frame 11 and is movably mounted inside the second pulley 123.

[0032] A monitoring assembly is movably mounted on the side wall of the screw 21, and the monitoring assembly includes a monitor 31, an impeller 32, a sealing cylinder 323 and an airbag 22. A frustum 211 is integrally formed at the bottom of the screw 21, and a mounting rod 214 is integrally formed above the frustum 211. The monitor 31 is rotatably mounted on the outside of the mounting rod 214, and the sealing cylinder 323 is located inside the monitor 31. A water inlet cylinder 312 and a water discharge cylinder 313 are integrally formed on the side wall of the monitor 31. The impeller 32 is movably mounted inside the water inlet cylinder 312. A fixing plate 222 is fixedly mounted on the side wall of the mounting rod 214. The airbag 22 is fixedly mounted between the fixing plate 222 and the sliding frame 11. An observation cylinder 111 is integrally formed on the top of the sliding frame 11. The observation cylinder 111 and the airbag 22 are connected to each other.

[0033] A rotating rod 321 is slidably inserted into the side wall of the impeller 32, and a swivel 33 is movably installed at the opening of the side wall of the sealing cylinder 323. The rotating rod 321 is movably inserted into the side wall of the swivel 33, and the side wall of the rotating rod 321 and the inner wall of the swivel 33 are respectively integrally formed with two side plates 1 324 and two side plates 2 333.

[0034] like Figure 4 、 Figure 5 and Figure 7 As shown, the sealing cylinder 323 is fixedly installed on the outside of the mounting rod 214, the inner wall of the monitor 31 is rotatably installed between the sealing cylinder 323 and the mounting rod 214, and the side wall of the monitor 31 is integrally formed with a guide plate 314.

[0035] Among them, the direction from the water inlet cylinder 312 to the drainage cylinder 313 is the same as the direction of water flow. When the flow direction of water at different depths changes, the water hits the side wall of the guide plate 314, causing the monitor 31 to deflect and adjust the direction from the water inlet cylinder 312 to the drainage cylinder 313, so that the direction from the water inlet cylinder 312 to the drainage cylinder 313 is the same as the direction of water flow again.

[0036] like Figure 2-Figure 5 As shown, an observation plate 113 is provided on the side wall of the observation tube 111 , and a connecting pipe 221 is fixedly connected to the top of the observation tube 111 . The connecting pipe 221 passes through the screw 21 to the opening of the side wall of the sealing tube 323 .

[0037] Among them, the working principle of the airbag 22 is: when the screw 21 moves downward, the screw 21 drives the fixed plate 222 to move downward, so that the fixed plate 222 stretches the airbag 22, and the airbag 22 draws out the water and air inside the observation tube 111 and the connecting tube 221, so that the connecting tube 221 draws out the water inside the monitor 31 and discharges it into the inside of the observation tube 111.

[0038] like Figure 4 and Figure 7As shown, a second slide groove 315 is provided on the inner wall of the water inlet cylinder 312 , and the impeller 32 is movably installed inside the second slide groove 315 . A first spring 322 is provided between the side wall of the impeller 32 and the inner wall of the monitor 31 .

[0039] like Figure 2 and Figure 7 As shown, the side wall of the drainage cylinder 313 is provided with a slide groove 319, and a slide plate 311 is slidably installed inside the slide groove 319. The side wall of the slide plate 311 is provided with a through hole 317, and the through hole 317 and the drainage cylinder 313 are interconnected. A water plate 318 is integrally formed on the top of the slide plate 311, and the water plate 318 is located above the monitor 31.

[0040] Among them, when the screw 21 moves downward, the water body hits the water plate 318, so that the water plate 318 drives the slide plate 311 to slide inside the slide groove three 319 and block the drainage tube 313. Through the blocking of the slide plate 311, the water body stops entering the water inlet tube 312, causing the impeller 32 to stop rotating. When the screw 21 stops moving downward, the slide plate 311 slides inside the slide groove three 319 again. At this time, the through hole 317 and the drainage tube 313 are connected to each other, and the water body enters the water inlet tube 312 again, causing the impeller 32 to continue rotating.

[0041] like Figure 5 、 Figure 8 and Figure 9 As shown, a second spiral groove 334 is provided on the inner wall of the rotating ring 33, and a second sliding ball 325 is integrally formed on the side wall of the rotating rod 321. The second sliding ball 325 is slidably installed inside the second spiral groove 334. A second spring 331 is provided between the rotating ring 33 and the sealing cylinder 323, and a third spring 332 is provided between the rotating rod 321 and the rotating ring 33.

[0042] Among them, when water enters the water inlet cylinder 312, the water drives the impeller 32 to rotate, and at the same time the water impacts the impeller 32, causing the impeller 32 to squeeze the spring 1 322, and the flow rate and flow of the water are monitored by the rotation speed of the impeller 32, and the impact force of the water is monitored by the distance moved by the impeller 32. When the impeller 32 rotates, the impeller 32 is reset by the spring 1 322. When the impeller 32 rotates, the impeller 32 drives the rotating rod 321 to rotate, and the sliding ball 2 325 slides inside the spiral groove 2 334 and slides to the end of the spiral groove 2 334. At this time, the rotating rod 321 drives the rotating ring 33 to rotate.

[0043] Further references Figure 5 、 Figure 8 and Figure 9To illustrate, the side surfaces of side panel 1 324 and side panel 2 333 are inclined. When water enters the water inlet cylinder 312, the rotating rod 321 drives the rotating ring 33 to rotate, and the side panel 1 324 and the side panel 2 333 separate, and the water enters the interior of the observation cylinder 111 through the connecting pipe 221. When the slide plate 311 moves and blocks the drainage cylinder 313, the impeller 32 and the rotating rod 321 stop rotating, and the spring 332 pulls the rotating rod 321, and the rotating rod 321 slides toward the rotating ring 33, and the inclined surfaces of the side panel 1 324 and the side panel 2 333 rotate with each other, so that the side panel 1 324 and the side panel 2 333 are arranged alternately, blocking and closing the connecting pipe 221. When the screw 21 moves upward, the airbag 22 is retracted. The water inside the airbag 22 is discharged to the inside of the monitor 31 through the connecting pipe 221. At this time, the water impacts the side plate 1 324, and the side plate 1 324 and the side plate 2 333 are separated, so that the impeller 32 is flushed and cleaned. The impeller 32 rotates, and the rotating rod 321 drives the rotating ring 33 to rotate. At this time, the water impacts the side plate 1 324 and the side plate 2 333, so that the water splashes to the inner wall of the monitor 31 and cleans it. The rotating ring 33 and the rotating rod 321 are moved toward the impeller 32 through the impact of the water, so that the splashed water flushes and cleans the water inlet cylinder 312. As the impact force of the water decreases, the spring 2 331 pulls the rotating ring 33, so that the rotating ring 33 drives the rotating rod 321 to return to its position, and flushes and cleans the water inlet cylinder 312 again.

[0044] like Figure 1 、 Figure 3 and Figure 6 As shown, the side wall of the screw 21 is provided with a plurality of evenly distributed spiral grooves 212 and slide grooves 213, which are interconnected and correspond one to one. The inner wall of the pulley 2 123 is integrally formed with a sliding ball 124, which is slidably installed inside the spiral groove 212 and the slide groove 213.

[0045] like Figure 1 and Figure 2 As shown, an electric push rod 112 is fixedly installed inside the fixed seat 1, and the output end of the electric push rod 112 is fixedly connected to the bottom of the sliding frame 11. An electric motor 12 is fixedly installed inside the sliding frame 11, and the output shaft of the electric motor 12 is fixedly connected to a pulley 121. A belt 122 is provided between the pulley 121 and the pulley 2 123.

[0046] Among them, the motor 12 rotates intermittently, and the number of revolutions of the motor 12 is the number of revolutions of a section of spiral groove 1 212 and a section of slide groove 1 213. When the rotation is completed, the motor 12 stops. After monitoring by the monitor 31, the motor 12 starts again and continues to rotate for the number of revolutions of a section of spiral groove 1 212 and a section of slide groove 1 213.

[0047] A water conservancy intelligent monitoring method, which uses the above-mentioned water conservancy intelligent monitoring device, specifically includes the following steps: S1, after fixing the fixing seat 1 on the shore, starting the electric push rod 112, causing the electric push rod 112 to shrink and drive the sliding frame 11 to slide downward, and when the electric push rod 112 shrinks to the limit position and closes, starting the motor 12, the pulley 121 drives the pulley 2 123 to rotate through the belt 122, and the pulley 2 123 drives the screw 21 to move downward through the sliding ball 124, so that the monitor 31 is immersed in the water body; S2, the sliding ball 124 slides from the sliding groove 1 213 to the inside of the spiral groove 1 212, so that the screw 21 drives the monitor 31 to move downward, and in the process of the monitor 31 moving downward, the water body pushes the water plate 318, causing the slide plate 311 to slide upward, the drainage tube 313 is closed, the impeller 32 and the rotating rod 321 stop rotating, and the side plate 1 324 and the side plate 2 333 are arranged alternately, so that the sealing tube 323 The opening of the screw 21 is closed, and the screw 21 stretches the airbag 22 through the fixing plate 222, so that the airbag 22 extracts the liquid and gas inside the observation tube 111 and the connecting tube 221, so that a negative pressure is formed inside the observation tube 111 and the connecting tube 221; S3, when the sliding ball 124 slides from the spiral groove 212 to the inside of the sliding groove 213, the motor 12 is turned off, and at this time the water enters the interior of the monitor 31 through the water inlet cylinder 312 and is discharged from the water discharge cylinder 313, and the water enters the water inlet cylinder 312. When inside the cylinder 312, the water body collides with and drives the impeller 32 to move and rotate. The impact force of the water body is monitored by the movement of the impeller 32, and the flow rate and flow of the water body are monitored by the rotation speed of the impeller 32. The impeller 32 drives the rotating rod 321 to rotate, so that the side plate 324 slides out of the interior of the rotating ring 33, and the opening of the sealing cylinder 323 is opened. The connecting pipe 221 draws the liquid inside the monitor 31 to the interior of the observation cylinder 111, and the quality of the water body is monitored through the observation plate 113.

[0048] It is further explained that the above-mentioned fixed connection should be understood in a broad sense unless otherwise clearly specified and limited. For example, it can be welding, gluing, or one-piece molding, etc., which are conventional means well known to those skilled in the art.

[0049] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
