Description

Technical Field

[0001] The invention relates to the technical field of sediment content detection, in particular to a device for detecting sediment content in a water conservancy flow. Background Art

[0002] In water conservancy projects, the detection of water flow sediment content is an essential detection item. Sediment content refers to the mass of dry sediment contained in a unit volume of water-sand mixture. Monitoring the sediment content in water bodies has multiple functions. It can help study the characteristics of water bodies, understand the concentration of suspended particles in water bodies, and conduct in-depth research on the nature and evolution of water bodies. At the same time, the detection of sediment content can also help evaluate the degree of water pollution and provide a basis for water quality assessment and management.

[0003] When detecting the sediment content of water flow, a sand content detector is usually used. When in use, the sensor probe of the sand content detector is placed in the water, and the sediment content of the water flow is detected by the sensor probe. However, the placement angle of the sensor probe in the water cannot be automatically adjusted according to the water flow velocity and the level of sediment content. When the water flow velocity is high, the stability and accuracy of the probe detection may be affected by eddy currents on the probe surface or the direct impact of high-speed water flow on the sensor. In addition, the direct impact of high-sediment content water on the sensor surface and the risk of sediment deposition may also be high, which in turn affects the accuracy of the sensor probe detection. For this reason, we propose a water conservancy water flow sediment content detection device. Summary of the Invention

A mounting block 45 fixed to the support 28 is provided on one side of the pressure plate 44. A pressure sensor 46 is installed on the side of the mounting block 45 close to the pressure plate 44. A guide frame 49 fixed to the support 28 is movably provided on the outer side of the second pull rope 42 and the third pull rope 411, which can respectively guide the second pull rope 42 and the third pull rope 411.

[0055] When the water flow rate is large, the impact of the water on the detection member 41 will be large, and the downward rotation of the detection member 41 around the connection position with the bracket 25 will be large, which will cause the pulling force on the second pull rope 42 to be large, and the pulling force on the slide 381 of the second winding member 43 to be large, which will cause the pressing force on the pressure plate 44 to be large, and the pressure detected by the pressure sensor 46 to be large; the controller controls the telescopic end of the second electric push rod 415 to drive the slide 381 of the fourth winding member 414 to move away from the connecting member 27, and the fourth pull rope 416 drives the sealing plate 410 to move upward, and the third spring 412 is compressed to open the water inlet on one side of the collecting shell 48, and the water enters the collecting shell 48 through the water inlet, and the sand in the water is filtered into the collecting shell 48 through the filter screen 413. The water can flow out of the collection shell 48 through the filter 413. After a certain period of time, the telescopic end of the second electric push rod 415 will be controlled to drive the slide 381 of the fourth winding member 414 to move in the opposite direction and reset. Under the elastic force of the third spring 412, the sealing plate 410 is moved down and reset to block the water inlet of the collection shell 48. Therefore, when the water flow contains a lot of sand, more sand will enter the collection shell 48 within a certain period of time, so that the collection shell 48 has a greater pulling force on the third pull rope 411, and then the pulling force on the slide 381 of the third winding member 47 is greater, so that the pressing effect on the pressure plate 44 is greater, so that the pressure detected by the pressure sensor 46 is greater, so that the water flow rate and the sand content of the water body can be synchronously detected by the pressure sensor 46, and then the limit component 5 can be synchronously regulated.

[0056] The limiting assembly 5 includes a second electromagnetic block 51 fixed on the upper side of the support 28, the second electromagnetic block 51 is electrically connected to the pressure sensor 46, the second electromagnetic block 51 is arranged on one side of the slide 381 of the first winding member 38, and a connecting block 52 is provided on one side of the second electromagnetic block 51 and is slidably arranged on the upper side of the support 28. A magnetic block 53 is fixed on the side of the connecting block 52 close to the second electromagnetic block 51. After power is turned on, the magnetic block 53 and the second electromagnetic block 51 repel each other, and a first switch 54 is installed on one side of the connecting block 52. The first switch 54 is electrically connected to the first electric push rod 39, and a limiting block 55 is provided on one side of the connecting block 52 and is fixed on one side of the connecting block 52 and is slidably arranged with the limiting block 55. The guide rod 56 can limit and guide the movement of the connecting block 52, and a fourth spring 57 is fixed on one side of the limiting block 55 and is fixed on the guide rod 56.

[0057] Initially, one side of the carriage 381 of the first winding member 38 presses against the first switch 54. For water bodies with high flow rates and high sediment content, the pressure detected by the pressure sensor 46 will be relatively large, making its resistance relatively small and the current in the circuit relatively large, which can make the second electromagnetic block 51 produce a larger repulsive effect on the magnetic block 53, so that the connecting block 52 moves a relatively large distance away from the second electromagnetic block 51. The fourth spring 57 is stretched and makes the carriage 381 of the first winding member 38 no longer press against the first switch 54, so that the first electric push rod 39 works, and the telescopic end of the first electric push rod 39 drives the carriage 381 of the first winding member 38 to move away from the connecting member 27. When one side of the carriage 381 of the first winding member 38 moves to press against the first switch 54 again, the first electric push rod 39 stops working. The distance that the slide 381 of the winding member 38 moves away from the connecting member 27 will be relatively large, which will cause the first pull rope 36 to pull the gear condition 33 upward a relatively large distance, so that the deflection angle of the sensor probe 13 is relatively large, so as to reduce the eddy current on the surface of the probe 13, improve the detection stability, reduce the direct impact of high-speed water flow on the sensor probe 13, reduce mechanical damage or data offset, and reduce the direct impact of high-sediment content water on the surface of the sensor probe 13 and the risk of sediment deposition, and reduce the abrasion of high-sediment content water on the surface of the probe 13, thereby improving the stability and accuracy of the sensor probe 13 detection; and through the setting of the limit block 55, the maximum distance that the connecting block 52 moves away from the second electromagnetic block 51 can be limited, and the maximum deflection angle of the probe 13 can be limited by the limiting effect of the upper end of the limit groove 34 on the gear condition 33 to prevent affecting the detection of the probe 13.

[0058] The side end of the support rod 26 is provided with a plurality of guide members 62 at equal intervals, that is, the guide members 62 at the side end of the support rod 26 are provided at equal intervals along the support rod 26. The upper and lower sides of the guide members 62 are rotatably provided with fixed shells 61 fixed to the support rod 26. A torsion spring 63 is provided between the fixed shell 61 and the guide member 62. For the first pull rope 36, the second pull rope 42, the third pull rope 411 and the fourth pull rope 416 arranged along the side end of the support rod 26, when they are arranged, The guide member 62 at the side end of the support member 26 rotates around the fixed shell 61 to open, and the first pull rope 36, the second pull rope 42, the third pull rope 411, and the fourth pull rope 416 are respectively placed inside the corresponding guide member 62. Then, under the action of the torsion spring 63, the guide member 62 is closed, so that the first pull rope 36, the second pull rope 42, the third pull rope 411, and the fourth pull rope 416 arranged along the side end of the support member 26 can be guided respectively by the multiple guide members 62.

[0059] A protective shell 64 is fixedly provided on the upper side of the support 28. The protective shell 64 can protect the components on the upper side of the support 28. The protective shell 64 can be set to be transparent. The rotating parts 383 of the first winding member 38, the second winding member 43, the third winding member 47 and the fourth winding member 414 respectively move through the side ends of the protective shell 64 to facilitate the rotation of the corresponding rotating parts 383.

[0060] Example 2

[0061] like Figure 6 and Figure 17 As shown, in this embodiment, other structures remain unchanged, and the difference from the first embodiment is that: a warning component 7 is provided on the upper side of the support 28, and the warning component 7 adjusts the cleaning cycle of the probe 13 according to the water flow rate and the sand content of the water body detected by the detection component 4, and the warning component 7 includes a rack rod 71 fixed on one side of the slide 381 of the first winding member 38, and one side of the rack rod 71 is meshed with a second gear 72, and the middle part of the second gear 72 is rotatably provided with a first rod 73 fixed to the upper side of the support 28, and the second gear 72 The upper side is fixed with an eccentric wheel 74, which is eccentrically rotated with the first rod 73. One side of the eccentric wheel 74 is abutted with a moving block 75 that is slidably arranged with the support 28. The upper side of the support 28 is symmetrically provided with a fourth sliding groove that is adapted to the moving block 75. The moving block 75 slides along the fourth sliding groove, which can limit and guide the movement of the moving block 75. A fifth spring 718 is symmetrically fixed on one side of the moving block 75. One side of the two fifth springs 718 is fixed with a fixed block 7 fixed to the upper side of the support 28. 19, a second rod 76 is fixed on the upper side of the moving block 75, and a first rotating wheel 77 is rotatably provided on the upper side of the second rod 76. A reduction motor 78 fixed to the upper side of the support 28 is provided on one side of the moving block 75, and a second rotating wheel 79 is fixed on the output shaft of the reduction motor 78. A rubber sleeve 710 is fixed on the outer side of the first rotating wheel 77 and the second rotating wheel 79. The two rubber sleeves 710 are arranged in abutment with each other. A toothed wheel 711 is fixed on the upper side of the first rotating wheel 77 and is rotatably provided with the second rod 76. A toothed wheel 711 is provided on one side. The third gear 712 has a toothed protrusion on the outer side of the toothed wheel 711, which is adapted to the tooth groove of the third gear 712. A third rod 713 is rotatably provided in the middle of the third gear 712 and fixed to the upper side of the moving block 75. A support column 714 is provided on one side of the third gear 712 and fixed to the upper side of the moving block 75. A second switch 715 is installed on one side of the support column 714. A pressure block 716 is fixed on the upper side of the third gear 712. A warning device 717 electrically connected to the second switch 715 is installed on one side of the support 28.

[0062] The first gear 72 of the second rotating wheel 77 is rotated by the gear 714 and the second gear 72 is rotated by the gear 716. The second gear 72 is rotated by the gear 717 and the second gear 72 is rotated by the gear 718. The first runner 77 and the rubber sleeve 710 outside the first runner 77 can be driven to rotate more effectively, that is, for water bodies with high flow rates and high sediment content, the angle of rotation of the first runner 77 can be driven to be relatively large, and the rotation of the first runner 77 will drive the rotation of the toothed wheel 711. Every time the toothed wheel 711 rotates one circle, it will drive the third gear 712 to rotate once. When the third gear 712 rotates one circle, the pressure block 716 will press the second switch 715, causing the alarm 717 to sound an alarm to remind the detection personnel to clean the sensor probe 13, thereby ensuring the stability and accuracy of the detection of the probe 13. Moreover, for water bodies with high flow rates and high sediment content, the alarm 717 can be controlled to sound an alarm relatively quickly to shorten the cleaning cycle and ensure the detection use of the probe 13.
