Description

Technical Field

[0001] The invention relates to the technical field of hydrological sediment sampling, and in particular to a device and method for surveying and sampling the sediment content of a hydraulic flow. Background Art

[0002] Sediment testing is a very important basic work in hydrological work. By sampling and analyzing the suspended sediment content in natural rivers, the sediment data of river water bodies can be obtained. There are two main types: instantaneous and cumulative. The most commonly used instantaneous sampler is the horizontal sampler.

[0003] A new type of horizontal sediment sampler control device disclosed in the patent application with reference publication number CN210863273U includes a sampling tube, two fixed plates spaced apart are welded and fixed at the center of the outside of the horizontally arranged sampling tube, a screw stepper motor is installed between the two fixed plates, the telescopic end of the screw stepper motor is vertically arranged downward, and connecting seats are symmetrically fixed on both sides of the upper part of the sampling tube, and support claws are rotatably connected to the connecting seats, and barrel covers are installed on the support claws, and the inner surfaces of the barrel covers on both sides are connected by springs. The utility model remote digital signal controls the horizontal suspended sediment sampler, and uses a screw stepper motor to drive the closing of the two compartment door supports of the sampler to achieve instantaneous closure of the sampling compartment of the sampler underwater. At the same time, signal feedback information is sent through the reed switch to ensure accurate sampling action, stable and reliable sampling work, and safe use.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0026] like Figures 1 to 12 As shown, a water conservancy water flow sediment content survey sampling device and method, including the following embodiments: Embodiment 1: Figure 1 , Figure 2 and Figure 3 As shown, it includes a support shell 1, a lead fish 4 for measuring flow velocity is fixedly connected to the bottom of the support shell 1, and the support shell 1 includes two side disc shells 101 arranged opposite to each other, and the two side disc shells 101 are fixedly connected by a plurality of mounting members 102, and also includes: A rotating disk 5 is disposed between the two side disc shells 101, and the rotating disk 5 is rotatably connected to the side disc shells 101. A plurality of sampling and intercepting grooves 501 for intercepting water samples are provided inside the rotating disk 5. An outer gear ring 502 is fixedly connected to the outer side of the rotating disk 5, and the outer gear ring 502 extends to the outer side of the side disc shell 101. A water transverse pipe 2 is fixedly connected to the outside of the side disc shell 101, and a flow slot 103 is opened on the outside of the side disc shell 101. The two water transverse pipes 2 are fixedly connected to the mounting frame 3 at one end away from the side disc shell 101. The center of the two water transverse pipes 2 and the sampling interception slot 501 are in the same straight line when the rotating disk 5 is in a stationary state. A sealing mechanism for sealing is provided on the outside of the mounting frame 3; The traction mechanism is arranged on the top of the rotating disk 5. When the rotating disk 5 rotates, the traction mechanism pulls the two sealing mechanisms to seal the ports of the water cross pipe 2. During the sealing process, multiple sampling interception grooves 501 intercept water flows at different stages.

[0027] In specific implementation, in the actual sampling process, the whole device is usually lowered to a suitable height in the water by a hanging rope. After a period of time, there are covers at both ends, and the cover edges are equipped with tension springs. When sampling, the cylinder cover is opened, and water flows through the cylinder. Then the switch is operated to close the cylinder cover by the spring tension to collect water samples. When the cylinder cover is sealed, it will inevitably be affected by the pulsation of sediment, thereby causing errors in detection. Therefore, in this scheme, water is used to pass through the water cross pipe 2 and the sampling interception groove 501 on the rotating disk 5 in sequence and discharge another water cross pipe 2; through the driving electric motor set on the side disc shell 101 The machine drives the rotating disk 5 to rotate, and the driving motor can be provided with a waterproof cover on the outside for protection. When the rotating disk 5 rotates, the water at one of the sampling interception grooves 501 is cut off and preserved; during the rotation of the rotating disk 5, the traction mechanism on the top of the rotating disk 5 drives the sealing assembly on the mounting frame 3 to seal the water cross pipe 2. During the sealing process, the sampling interception groove 501 is continuously sampled to intercept and preserve the water samples during the sealing process, and the sealing mechanism samples water at each stage of the sealing process, so that the accuracy of the sand content in the water flow can be intuitively detected through multiple groups of water samples.

[0028] Embodiment 2: Figure 5 , Figure 6 and Figure 7 As shown, the sealing mechanism includes: A plurality of sealing baffles 301, wherein the plurality of sealing baffles 301 are arranged on one side of the installation frame 3 and are arranged in a ring around the center of the installation frame 3; Multiple driving racks 302 are respectively arranged at the bottom of multiple sealing baffles 301, and one end of the driving rack 302 away from the installation frame 3 is fixedly connected to the sealing baffle 301, and the driving rack 302 passes through the installation frame 3 and is slidably connected to the installation frame 3.

When the rotating inner gear ring 303 rotates, the driving racks 302 are driven by the transmission parts to push multiple sealing baffles 301 to approach the center of the installation frame 3 to seal the water horizontal pipe 2.

[0030] Transmission parts include: A plurality of transmission rods 304, the plurality of transmission rods 304 correspond to the plurality of sealing baffles 301 one by one, and the transmission rods 304 are disposed inside the installation frame 3 and are rotatably connected to the installation frame 3; A second gear 307 fixedly connected to the outer side of the transmission rod 304, the second gear 307 is meshedly connected with the rotating inner gear ring 303; The first gear 305 is fixedly connected to one end of the transmission rod 304 , and the first gear 305 is meshedly connected with the driving rack 302 .

[0031] During specific implementation, the traction mechanism drives the rotating inner gear ring 303 inside the installation frame 3 to rotate, and the rotating inner gear ring 303 drives multiple meshing connected second gears 307, and the second gear 307 drives the fixedly connected first gear 305 to rotate through the transmission rod 304, and the first gear 305 drives the driving rack 302 to move through meshing, so that the driving rack 302 drives the fixedly connected sealing baffle 301 to move toward the center of the installation frame 3. As the traction mechanism continues to rotate, multiple sealing baffles 301 approach each other, and then the sealing baffle 301 closes the water inlet of the installation frame 3, and the water inlets at both ends of the two installation frames 3 are closed, thereby avoiding the influence of the existing spring tension on closing the cylinder cover.

[0032] Embodiment 3: Figure 3 , Figure 4 and Figure 7 , the traction mechanism includes: A driving rotating rod 603, which is disposed on the top of the outer gear ring 502, and a third gear 601 is fixedly connected to the outer side of the driving rotating rod 603, and the third gear 601 is meshedly connected with the outer gear ring 502; Two support plates 602, the two support plates 602 are respectively fixedly connected to the two side disc shells 101, and the two ends of the driving rotating rod 603 respectively pass through the two support plates 602 and are rotatably connected to the support plates 602, for supporting the driving rotating rod 603; Two winding reels 604, the two winding reels 604 are respectively arranged at two ends of the driving rotating rod 603, the winding reels 604 and the winding reels 604 are detachably connected, and the winding reels 604 are driven to rotate by the driving rotating rod 603; A sliding support plate 606 is fixedly connected to the outer side of the rotating inner gear ring 303, the sliding support plate 606 penetrates the limiting ring 306 and is slidably connected to the limiting ring 306, one end of the sliding support plate 606 is rotatably connected to the contact wheel 608, and the contact wheel 608 contacts the inner wall of the mounting frame 3 to ensure the stable rotation of the rotating inner gear ring 303; A traction rope 607 is fixedly connected to the outside of the sliding support plate 606, the traction rope 607 passes through one side of the installation frame 3 along the side wall of the installation frame 3, and one end of the traction rope 607 is wound and fixedly connected to the outside of the winding drum 604; A guide wheel 605 is rotatably connected to the top of the side disc shell 101, and the guide wheel 605 is used to guide the traction rope 607; The elastic member 609 is arranged inside the installation frame 3, and its two ends are fixedly connected to the inner wall of the installation frame 3 and the sliding support plate 606 respectively, and is used to pull the sliding support plate 606 to reset after the sliding support plate 606 moves. The elastic member 609 can be a spring or an elastic belt.

[0033] In a specific implementation, a motor is driven on the outside of the side disc shell 101, and the output shaft of the driving motor drives the rotating disk 5 to rotate. Since the two sides of the rotating disk 5 are respectively in contact with the two side disc shells 101, when the rotating disk 5 rotates, the sampling interception groove 501 rotates to the inside of the side disc shell 101 without leakage. The rotation of the rotating disk 5 drives the outer gear ring 502 fixedly connected to the outside to rotate, and the outer gear ring 502 drives the meshing third gear 601 to rotate, and the third gear 601 drives the driving rotating rod 603 fixedly connected to the inside to rotate. When the driving rotating rod 603 rotates, the driving rotating rod 603 and the winding disk 604 are detachable. The detachable connection at this time can be fixed with bolts and nuts, or other types of bayonet plug-ins, which will not be further elaborated here. When the driving rod 603 rotates to drive the winding disk 604 to rotate, the winding disk 604 drives the traction rope 607 fixedly connected on the outside to reel in. At this time, one end of the traction rope 607 is connected to the sliding support plate 606, which in turn drives the sliding support plate 606 to move. Therefore, the sliding support plate 606 drives the fixedly connected rotating inner gear ring 303 to rotate, and then drives the sealing mechanism on the installation frame 3. When multiple installation frames 3 are sealed, sampling is performed at different stages to facilitate the later detection of the sand content in the water sample.

[0034] Embodiment 4: Figure 3 , Figure 8 and Fig. 9 As shown, a plurality of sampling and intercepting grooves 501 are provided with stirring members inside, and the stirring members include a rotating rod 500, and a plurality of stirring plates 503 are fixedly connected to the outer side of the rotating rod 500, and the stirring plates 503 are in contact with the inner wall of the sampling and intercepting grooves 501 for stirring the sediment.

[0035] It also includes a sample arrangement mechanism, which includes a discharge barrel 7 and an extrusion barrel 8. The discharge barrel 7 and the extrusion barrel 8 are respectively fixed on two side disc shells 101, and the discharge barrel 7 and the extrusion barrel 8 are kept on the same straight line with the center of a circle. A pushing member is arranged between the discharge barrel 7 and the extrusion barrel 8, and a driving member is arranged inside the extrusion barrel 8. A sample outlet groove 703 for discharging samples is opened on the outer side of the discharge barrel 7. The driving member inside the extrusion barrel 8 is driven by the pushing member to discharge the sample inside the corresponding sampling interception groove 501 through the sample outlet groove 703.

[0036] During the specific implementation, in the actual process of sampling, the equipment needs to be lifted after sampling, and the personnel will open the cover. Since the sand will settle and adhere to the inner wall, the amount of sand will be reduced, so errors are prone to occur during later testing. Therefore, in this solution, when the sample inside the corresponding sampling intercepting groove 501 needs to be taken out, the receiving box is placed under the sample outlet groove 703, and the driving member drives the stirring member to rotate through the pushing member to stir the silt and water, so that the sample is discharged together with the water, thereby avoiding the silt adhering to the inner wall of the sampling intercepting groove 501, and ensuring the accuracy of the sand content in the flowing water.

[0037] like Fig. 9 and Fig.10 As shown, in this embodiment: a first sealing disk 701 is provided inside the discharge barrel 7 and is slidably connected to the inside of the discharge barrel 7, the first sealing disk 701 is used to seal one end of the sampling interception groove 501, and a plurality of first springs 702 are fixedly connected between the first sealing disk 701 and one end inside the discharge barrel 7.

[0038] The driving member includes a second sealing disk 802 for sealing the other end of the sampling interception groove 501. The second sealing disk 802 is rotatably connected to the inside of the extrusion barrel 8. A plurality of scraping push plates 8042 are arranged at the front of the second sealing disk 802. A plurality of stirring plates 503 are fixedly connected to magnetic strips on one side close to the second sealing disk 802. A magnetic plate 8021 corresponding to the plurality of stirring plates 503 is fixedly connected to the second sealing disk 802 on one side close to the rotating disk 5. The plurality of magnetic plates 8021 are magnetically adsorbed to the magnetic strips. A fixed rod 803 is fixedly connected between one end of the inside of the second sealing disk 802. The fixed rod 803 is rotatably connected to the second sealing disk 802, and a spiral groove is provided on the outside of the fixed rod 803.

[0039] In specific implementation, when the rotating disk 5 rotates to take samples, one of the sampling intercepting grooves 501 is located between the discharge barrel 7 and the extrusion barrel 8. At this time, the first sealing disk 701 and the second sealing disk 802 seal the sampling intercepting groove 501, and a magnetic strip on a plurality of stirring plates 503 is fixedly connected to one side of the second sealing disk 802 for adsorption. Under the action of magnetic attraction, the stirring plates 503 correspond one-to-one with the magnetic plates 8021, so that each stirring plate 503 is adjacent to the two scraping push plates 8042, ensuring that the stirring member can maintain the same state every time.

[0040] like Fig.10 , Fig.11 and Fig.12As shown, in this embodiment, the pushing member includes a sliding disk 801 arranged inside the extrusion cylinder 8, the sliding disk 801 is sleeved on the outside of the fixed rod 803, and one side of the sliding disk 801 is rotatably connected to a movable cylinder 804, the movable cylinder 804 is sleeved on the outside of the fixed rod 803, and the inside of the movable cylinder 804 is fixedly connected to a contact shaft 8041, the contact shaft 8041 extends to the outside of the fixed rod 803 and is provided with an interior of a spiral groove, and is slidably matched with the fixed rod 803, a connecting rod 8043 is fixedly connected between the movable cylinder 804 and a plurality of scraping push plates 8042, a plurality of connecting rods 8043 penetrate the second sealing disk 802 and are slidably connected to the second sealing disk 802, a pushing handle 9 is fixedly connected between the sliding disk 801 and the first sealing disk 701, and a second spring 805 is fixedly connected between the sliding disk 801 and the second sealing disk 802.

[0041] In a specific implementation, when a person pulls the push handle 9 to move the push handle 9 toward one end of the discharge barrel 7, the push handle 9 drives the first sealing disk 701 fixedly connected thereto to move. At this time, the sample inside the sampling interception groove 501 flows into the inside of the discharge barrel 7, and the extrusion barrel 8 fixedly connected to the other end of the push handle 9 moves toward the rotating disk 5. The rotating movable barrel 804 on the sliding disk 801 slides on the fixed rod 803, and a spiral groove is provided on the outer side of the fixed rod 803. The contact shaft 8041 inside the movable barrel 804 is rotated in the spiral groove. The movable cylinder 804 is driven to rotate under the restriction of the groove. The movable cylinder 804 drives the scraper push plate 8042 to be inserted into the outside of the stirring plate 503 through multiple connecting rods 8043, driving the multiple stirring plates 503 to rotate and stir, and push the water sample inside the sampling intercepting groove 501 to be squeezed into the inside of the discharge cylinder 7, so that the silt and water are discharged together through the sample outlet groove 703, and the water samples inside the multiple sampling intercepting grooves 501 are discharged in turn, thereby avoiding the silt adhering to the inner wall of the sampling intercepting groove 501, and ensuring the accuracy of detecting the sand content in the flowing water.

[0042] It is worth noting that in order to prevent the sealing mechanism from continuing to start, the reel 604 and the driving rod 603 are first disassembled, and then the elastic member 609 pulls and rotates the inner gear ring 303 to reset, so that the opening of the installation frame 3 is opened, and the personnel take out the water sample; In addition, in the present solution, sealing gaskets are arranged on the outsides of the sealed components to improve the sealing performance.

[0043] A method for surveying and sampling the sediment content of a hydraulic flow comprises the following steps: Step 1: lower the whole device to a suitable height in the water by means of a lifting rope, so that the water passes through the water horizontal pipe 2 and one of the sampling interception slots 501; Step 2: The driving motor provided on the side disc shell 101 drives the rotating disc 5 to rotate. When the rotating disc 5 rotates, the water at one of the sampling interception slots 501 is intercepted and stored; Step 3: During the rotation of the rotating disk 5, the traction mechanism on the top of the rotating disk 5 drives the sealing assembly on the mounting frame 3 to seal the water cross pipe 2. During the sealing process, the sampling interception groove 501 continuously intercepts and stores the water samples during the sealing process.
