Description

Technical Field

[0001] The invention relates to the technical field of water level monitoring, and in particular to a watershed water environment monitoring device. Background Art

[0002] General water environment monitoring data include indicators such as water quality and water level of surface water environments such as rivers, lakes and reservoirs. Specific monitoring indicators include water temperature, water level, flow, PH, DO, turbidity, conductivity, COD, ammonia nitrogen, total phosphorus, total nitrogen, etc.

[0003] Among them, water level monitoring is an important indicator for water environment monitoring of rivers, lakes and reservoirs. When groundwater pumping, rainfall, etc. are being carried out, it is necessary to monitor the groundwater level in real time to prevent the water level from changing too quickly or too much, which may affect river embankments and other construction projects.

[0004] Existing water level monitoring generally uses a magnetostrictive float to monitor the water level. A magnetic float is required to measure the liquid level outside the measuring rod of the level meter as the liquid surface moves. Due to the limitation of the measuring rod, it can only move up and down on the measuring rod. However, the water in rivers and lakes is generally flowing water. When the water flow hits the magnetic float, it will cause the magnetic float to move upward, which will cause the sensor to be unable to measure accurately.

[0005] To this end, we propose a watershed water environment monitoring device to solve the above problems. Summary of the invention

A sliding rod is provided on the sliding rod, and a floating roller is connected between the two sliding rods.

[0021] 5. The present invention sets up connecting parts such as a monitoring mechanism and a transmission mechanism. Under the transmission of the transmission mechanism, the monitoring mechanism periodically moves and rotates, so that the debris attached to its side wall can be thrown off to avoid affecting the floating roller.

[0029] The technical solutions in the embodiments of the present invention will be described clearly and completely 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 is necessary to understand that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship are based on the orientation or position relationship shown in the 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 orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0031] Reference Figure 1-6 A watershed water environment monitoring device includes a connecting frame 1 horizontally erected on a river bank, and also includes a lifting mechanism 2, a transmission mechanism 4 and a monitoring mechanism 5 arranged on the connecting frame 1. The transmission mechanism 4 includes a water wheel assembly and a conveyor belt assembly. The lifting mechanism 2 is used to drive the water wheel assembly to move up and down. The monitoring mechanism 5 includes a distance sensor 506. Two groups of brackets 3 are symmetrically arranged on the lower side of the connecting frame 1, and the number of each group is two. The conveyor belt assembly is arranged on the two groups of brackets 3, and the conveyor belt assembly is connected to the monitoring mechanism 5. Under the transmission of the transmission mechanism 4, the monitoring mechanism 5 can perform water level monitoring operations in a relatively static state with the water flow.

[0032] Reference Figure 2-3 Specifically, the water wheel assembly includes two water wheel boxes 401, a water inlet 402, water wheel blades 403 and a connecting shaft 404. The two water wheel boxes 401 are rotatably connected with the water wheel blades 403. The two water wheel blades 403 are connected by the connecting shaft 404. The water wheel box 401 is provided with water inlets 402 at the front and rear sides along the water flow direction.

[0033] The conveyor belt assembly includes a belt 405, a first pulley 406, a conveyor belt 407, a second pulley 408 and two transmission rollers 409. The two transmission rollers 409 are respectively rotatably connected between each group of brackets 3. The conveyor belt 407 is wound around the two transmission rollers 409. The roller shaft of one of the transmission rollers 409 passes through the side wall of the bracket 3 and is coaxially connected to the second pulley 408. The wheel shaft of one of the water wheel blades 403 passes through the side wall of the water wheel box 401 and is coaxially connected to the first pulley 406. The belt 405 is passed between the first pulley 406 and the second pulley 408. The wheel diameters of the first pulley 406 and the second pulley 408 are consistent, thereby maintaining the synchronization of the transmission of the water wheel assembly and the conveyor belt assembly.

[0034] The device suspends the connecting frame 1 on the river bank or lake reservoir. When monitoring the water level, the transmission mechanism 4 is moved downward by the lifting mechanism 2 according to the water level until the water wheel box 401 is completely submerged in the water. When the water is in a low flow rate or non-flowing state, the transmission mechanism 4 basically does not work. At this time, the floating roller 504 floats on the water surface, and the distance sensor 506 is used to measure the distance of the floating roller 504.

[0035] When the water flows rapidly due to rain or other reasons, the flowing water passes through the water inlet 402 in the water wheel box 401, thereby driving the water wheel 403 to rotate. Therefore, the first pulley 406 and the second pulley 408 drive the transmission roller 409 to rotate under the joint action of the belt 405, and then drive the monitoring mechanism 5 to move synchronously under the transmission action of the conveyor belt 407. At this time, the monitoring mechanism 5 and the water flow remain relatively static, so that the floating roller 504 is not impacted by the water flow. At this time, the distance sensor 506 monitors the distance to the floating roller 504, so that the water level change can be understood;

[0036] Furthermore, two water wheel boxes 401 are symmetrically arranged on both sides of the floating roller 504, and the two water wheel boxes 401 work together to ensure that the transmission operation is more stable and reliable.

[0037] In addition, when monitoring the water level, it should be noted that the water wheel box 401 should be immersed in water to ensure the stability of the water flow. At the same time, it should avoid the water inlet 402 of the water wheel box 401 being affected by external interference such as wind when it is not completely in the water, resulting in the monitoring mechanism 5 being unable to strictly maintain a relatively static state with the water flow.

[0038] Reference Figure 2 , 4-5, specifically, the monitoring mechanism 5 also includes a monitoring frame 501, a strip opening 502, a slide bar 503, a floating roller 504, and a slider 505. The monitoring frame 501 is fixedly connected to the side wall of the conveyor belt 407. Two vertical strip openings 502 are symmetrically opened on both sides of the monitoring frame 501, and the slide bar 503 is fixedly set in the strip opening 502. The slide bar 503 is slidably sleeved on the slide bar 503, and a floating roller 504 is connected between the two slide bars 503.

[0039] By slidingly setting a floating roller 504 on the monitoring frame 501, the liquid level is automatically adjusted in real time by buoyancy. When setting, the monitoring mechanism 5 is set on the front side of the transmission mechanism 4. If the transmission mechanism 4 is set on its front side, the outer side of the water wheel box 401 is impacted by the water flow, which will cause turbulence in the water around it, so that the water flow between the two water wheel boxes 401 will increase in velocity, which will have a greater impact on the floating roller 504, causing it to jump up and down unstably, affecting the monitoring of the distance sensor 506. The floating roller 504 is strip-shaped and contacts a larger water surface than the float. The water level data monitored by the distance sensor 506 is more representative.

[0040] Specifically, a connecting plate 507 tilted upward is provided on the lower side of the monitoring frame 501 .

[0041] During operation, with the transmission of the transmission mechanism 4, the monitoring mechanism 5 will be periodically driven along the conveyor belt 407, and then the monitoring mechanism 5 will periodically monitor the water level. When the connecting plate 507 rotates from top to bottom and is ready to re-enter the water, the floating objects on the water surface can be pre-punched into the water through the connecting plate 507. If the floating objects are against the side wall of the connecting plate 507, the floating objects will slide along the inclined surface because the connecting plate 507 is inclined up and down, and the floating objects will be divided to the outside of the monitoring mechanism 5, so as not to affect the floating roller 504. In addition, the monitoring mechanism 5 rotates periodically, so as to throw away the debris attached to its side wall, so as to avoid affecting the floating roller 504.

[0042] Reference Figure 6 Specifically, a tensioning mechanism 6 for automatically tensioning the belt 405 is arranged on the side wall of one of the water wheel boxes 401, and the tensioning mechanism 6 includes a T-shaped guide rod 601, a support 602, a spring 603 and a tensioning roller 604. The support 602 is fixedly arranged on the side wall of the water wheel box 401, and a T-shaped guide rod 601 is slidably arranged on the side wall of the support 602, the lower end of the T-shaped guide rod 601 is fixedly connected to the tensioning roller 604, and the outer side of the T-shaped guide rod 601 is sleeved with a spring 603.

[0043] Specifically, the wheel diameter of the tensioning roller 604 is much smaller than the wheel diameters of the first pulley 406 and the second pulley 408, wherein the wheel diameter ratio of the three is 1:10:10. Since the wheel diameter of the tensioning roller 604 is smaller, it will not affect the transmission ratio of the other two pulleys, thereby ensuring synchronous transmission.

[0044] Before work, it is necessary to adjust the height of the water wheel box 401 in the transmission mechanism 4 through the lifting mechanism 2, and the transmission of the belt 405 to the first pulley 406 and the second pulley 408 needs to be adaptively adjusted in terms of tension. Through the telescopic effect of the spring 603, the T-shaped guide rod 601 will drive the tensioning roller 604 to always press tightly against the side wall of the belt 405, thereby ensuring that the belt 405 is always in a taut state, thereby ensuring the normal transmission of the first pulley 406 and the second pulley 408.

[0045] Reference Figure 1-3 Specifically, the lifting mechanism includes a motor 201, a threaded sleeve 202, a screw rod 203, a guide sleeve 204 and a guide column 205. The motor 201 is arranged at the upper end of the connecting frame 1. The driving shaft of the motor 201 passes through the side wall of the connecting frame 1 and is connected to the screw rod 203. The upper side wall of one of the water wheel boxes 401 is fixedly provided with a threaded sleeve 202. The screw rod 203 is threadedly connected to the threaded sleeve 202. The guide column 205 and the guide sleeve 204 are respectively arranged on the side walls of the connecting frame 1 and the other water wheel box 401.

[0046] By driving the motor 201 and under the threaded connection between the screw rod 203 and the threaded sleeve 202 , the height of the water wheel box 401 can be adjusted appropriately.

[0047] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
