Detailed Implementation

[0033] like Figures 1-11 As shown, an adjustable-distance shore-based hydrological data acquisition station includes a column 1 and a cantilever 2 installed on one side of the column 1. A detection component 5 is installed at the end of the cantilever 2. Specifically, the detection component 5 includes a water level gauge and a flow meter, etc., for collecting information such as water level and flow rate in the river channel. A control box 101 is also fixedly installed on the column 1. The information collected by the detection component 5 can be uploaded to the cloud or a terminal after being processed by the controller in the control box 101.

[0034] In practical use, it is also necessary to collect water from the river channel. Therefore, this design includes a sliding annular plate 6 below the cantilever 2, allowing the annular plate 6 to slide along the axis of the cantilever 2. (Refer to...) Figures 3-10 As shown, a turntable 11 is installed on one side inside the annular plate 6. The turntable 11 can rotate relative to the annular plate 6. Specifically, refer to... Figure 5 As shown, a retaining ring 1102 can be fixedly installed on the outer peripheral wall of the turntable 11, and an annular groove that cooperates with the retaining ring 1102 is opened on the inner wall of the annular plate 6, so that the retaining ring 1102 is rotatably installed in the annular groove. A through hole is provided in the center of the turntable 11, and the turntable 11 protrudes outward at the through hole to form a convex ring 1101. The turntable 11 and the annular plate 6 are in frictional transmission cooperation, and a sleeve 12 is provided in the axial direction of the annular plate 6. The sleeve 12 passes through the convex ring 1101 and is rotatably cooperated with it (a bearing can be installed between the sleeve 12 and the convex ring 1101). A snap-fit ​​member is provided on the convex ring 1101 to cooperate with the sleeve 12, so that the sleeve 12 can be locked with the convex ring 1101 through the snap-fit ​​member, so that the sleeve 12 can synchronously drive the convex ring 1101 and the turntable 11 to rotate.

[0035] The traction belt 7 is wound on the outer circumferential surface of the sleeve 12, one end of the traction belt 7 is fixedly connected with the sleeve 12, the other end of the traction belt 7 is connected with the sampling assembly, and the pressure rod 9 is arranged on the side close to the traction belt 7 of the rotating disc 11. The pressure rod 9 is elastically matched with the rotating disc 11 and can move along the diameter direction of the rotating disc 11. Initially, the pressure rod 9 is near the vertex of the rotating disc 11 and is pressed on the outside of the traction belt 7. For details, refer to the position of the pressure rod 9 in Figure 3 As the sleeve 12 gradually unwinds the traction belt 7, the pressure rod 9 can gradually approach the center position of the rotating disc 11 and always adhere to the outside of the traction belt 7. During the process of approaching the center of the rotating disc 11, the pressure rod 9 can be matched with the clamping piece, so that the convex ring 1101 and the sleeve 12 are locked by the clamping piece. In the case that the sleeve 12 and the convex ring 1101 are locked and the pressure rod 9 adheres to the outside of the traction belt 7, as the sleeve 12 rotates, the traction belt 7 will stop unwinding and reversely wind on the outside of the pressure rod 9 and the sleeve 12, so as to take out the sampling assembly below the water surface. Based on this, by adjusting the position of the clamping piece relative to the pressure rod 9, water sources at different depths can be sampled.

[0036] The clamping piece is arranged on the outer circumferential wall of the convex ring 1101 and elastically matched with the convex ring 1101. The bottom end of the clamping piece penetrates through the convex ring 1101 and can contact the outer circumferential wall of the sleeve 12. A plurality of clamping grooves 1202 matched with the clamping piece are uniformly arranged on the outer circumferential wall of the sleeve 12. When one end of the clamping piece penetrates through the convex ring 1101 and is inserted into the clamping groove 1202, the convex ring 1101 can be locked with the sleeve 12 and rotate synchronously.

[0037] Further, the clamping piece comprises a fixed frame 22 fixed on the outer circumferential wall of the convex ring 1101. A clamping strip 17 is elastically connected in the fixed frame 22. In actual use, when the bottom end of the clamping strip 17 is inserted into the clamping groove 1202, the sleeve 12 and the convex ring 1101 are locked. The top end of the clamping strip 17 is threadedly connected with a screw rod 21. During the process of approaching the center of the rotating disc 11, the clamping strip 17 is matched with the clamping groove 1202 by extruding the screw rod 21.

[0038] The sampling assembly comprises a sampling cylinder 8 and a sealing cover 19 which is slidingly attached to the inside of the sampling cylinder 8, and the end of the traction belt 7 away from the sleeve 12 is fixed to the top of the sealing cover 19, at least one positioning groove 1901 is formed on the outer side wall of the sealing cover 19, and a positioning block 20 which is matched with the positioning groove 1901 is elastically connected to the inner wall of the sampling cylinder 8 through a pre-set circular hole, specifically, a spring is fixedly arranged between the inner end face of the circular hole and the positioning block 20, one end of the positioning block 20 which is in the form of a spherical surface 2001 is inserted into the positioning groove 1901, and the gravity of the sampling cylinder 8 itself is not enough to make the positioning block 20 overcome the elastic force and be compressed into the circular hole, so that the sampling cylinder 8 can be kept stable with the sealing cover 19 in the unsampled state.

[0039] Further, as shown in Figure 7 , a first through groove 801 is formed on the outer side wall of the sampling cylinder 8, and a second through groove 1902 is formed on the peripheral surface of the sealing cover 19, when the positioning block 20 is matched with the positioning groove 1901, the second through groove 1902 is located below the first through groove 801, thereby avoiding the external water source entering the inside of the sampling cylinder 8 through the first through groove 801 and the second through groove 1902.

[0040] At least one stop block 802 is fixed on the inner wall of the sampling cylinder 8 at the top end position, so as to block the sealing cover 19 and avoid the sealing cover 19 moving out of the sampling cylinder 8.

[0041] In actual use, the driving annular plate 6 moves outward along the cantilever 2, so that the sampling cylinder 8 can approach the river channel, when the sampling cylinder 8 reaches the corresponding position, the sleeve 12 can be driven to rotate, so that the traction belt 7 can be unwound, so that the sampling assembly can be lowered into the river channel, because the pressure rod 9 is elastically matched with the rotating disc 11, therefore, as the traction belt 7 is gradually unwound from the outside of the sleeve 12, the pressure rod 9 can gradually approach the center of the rotating disc 11, when the pressure rod 9 contacts the screw rod 21 and continues to move, the pressure rod 9 can extrude the clamping strip 17, so that the clamping strip 17 moves towards the sleeve 12, when one end of the clamping strip 17 is inserted into the inside of the clamping groove 1202, the sleeve 12 can drive the convex ring 1101 and the rotating disc 11 to rotate synchronously, and the pressure rod 9 is attached to the outside of the traction belt 7, therefore, when the sleeve 12 drives the rotating disc 11 to rotate synchronously, the released traction belt 7 can be reversely wound on the outside of the pressure rod 9 and the sleeve 12, as shown in Figure 11 , as the traction belt 7 is reversely wound, the sampling assembly can be taken out of the water surface;

[0042] Specifically, through the specific structure of the sampling assembly, it can be known that: in the process of lowering the sampling assembly below the water surface, the cooperation between the positioning block 20 and the positioning groove 1901 can keep the sampling cylinder 8 and the sealing cover 19 stable, so as to avoid the external water source entering the inside of the sampling cylinder 8, and when the traction belt 7 stops the sampling assembly below and is reversely wound, the sampling cylinder 8 will keep the tendency of moving downward due to inertia, while the sealing cover 19 is instantaneously pulled upward by the reversely wound traction belt 7, in this process, the pressure on the positioning block 20 by the side edge of the positioning groove 1901 will sharply increase, so that the positioning block 20 can be compressed into the round hole against the elastic force, finally resulting in that the sealing cover 19 can move upward relative to the sampling cylinder 8 with the traction belt 7, when the first through groove 801 is aligned with the second through groove 1902, the water source can enter the sampling cylinder 8 through the first through groove 801 and the second through groove 1902, and when the sealing cover 19 moves upward and contacts the stop block 802, the first through groove 801 and the second through groove 1902 are misaligned, so as to avoid different depths of water source entering the sampling cylinder 8 during the sampling assembly is taken out of the water surface;

[0043] Based on the above structure, in the use process, when the rotating screw rod 21 adjusts its height, the pressing rod 9 can cooperate with the screw rod 21 after moving different distances and extrude the clamping strip 17 to make it cooperate with the clamping groove 1202, specifically, when the sampling of the deeper water source in the river channel is needed, the screw rod 21 can be rotated to move away from the pressing rod 9, in this way, the sleeve pipe 12 needs to release more traction belt 7 to make the pressing rod 9 contact with the screw rod 21 and extrude the clamping strip 17, similarly, when the sampling of the shallower water source is needed, the screw rod 21 can be rotated to move close to the pressing rod 9, in this way, the sleeve pipe 12 can release less traction belt 7, and the pressing rod 9 can contact with the screw rod 21, therefore, the use of this device is beneficial to the sampling of different depths of water source.

[0044] In actual use, scale lines can be arranged outside the screw rod 21, so as to accurately adjust the distance between the screw rod 21 and the pressing rod 9, thereby being able to control the length of the released traction belt 7, in addition, a display screen can be installed in the control box 101 for displaying the information collected by the detection assembly 5, or the information collected by the detection assembly 5 can be uploaded to the terminal through the controller in the control box 101, before sampling, the position of the screw rod 21 can be adjusted according to the current water level and the depth needed to be sampled.

[0045] Referring to Figures 3-10 As shown in the figure, the protrusion 16 is elastically connected to one end of the pressing rod 9 penetrating through the rotating disc 11, the protrusion 16 can move along the axis direction of the pressing rod 9, and the end of the protrusion 16 located outside the pressing rod 9 is provided with an inclined extrusion surface 1601, the annular plate 6 is fixedly connected with a positioning strip 15 at the position of the vertex through a support rod, and initially, the protrusion 16 is located at one side of the positioning strip 15;

[0046] Further, the elastic connection is provided on the surface of the pressure rod 9 with a slide bar 10, which can slide along the diameter direction of the pressure rod 9, and the slide bar 10 is fixedly connected with the vertical plate 1001 at the bottom of the slide bar 10, and the connecting rope 14 is fixed between the vertical plate 1001 and the protrusion 16, and the connecting rope 14 passes through the pressure rod 9 along the axis direction of the pressure rod 9 and is in sliding fit with the pressure rod 9, and the bottom end of the slide bar 10 is provided with a slope 1702. Figure 5 、 Figure 9 As shown in the figure, the vertical plate 1001 is fixedly connected at the bottom of the slide bar 10, and the connecting rope 14 is fixed between the vertical plate 1001 and the protrusion 16, and the connecting rope 14 passes through the pressure rod 9 along the axis direction of the pressure rod 9 and is in sliding fit with the pressure rod 9, and the bottom end of the slide bar 10 is provided with a slope 1702. Figures 5-6 、 Figure 10 As shown in the figure, the bottom end of the slide bar 17 is provided with a slope 1702.

[0047] In actual use, when the slide bar 17 is inserted into the clamping groove 1202 and the sleeve 12 is rotated to release the traction belt 7, the clamping groove 1202 can cooperate with the side of the slide bar 17 away from the slope 1702, so that the sleeve 12 can stably drive the rotating disc 11 to rotate, in this case, the inclined extrusion surface 1601 of the protrusion 16 will be in contact with the positioning strip 15, thereby avoiding the interference between the protrusion 16 and the positioning strip 15 when the protrusion 16 rotates with the rotating disc 11, when the pressure rod 9 is in contact with the traction belt 7 and reversely winds the traction belt 7, the slide bar 10 will be extruded into the pressure rod 9, in this process, the vertical plate 1001 that slides downward can pull the protrusion 16 through the connecting rope 14, so that the protrusion 16 is retracted into the pressure rod 9, which causes that the protrusion 16 will not be in contact with the positioning strip 15 in the process of reverse rotation of the sleeve 12 to release the traction belt 7 outside the pressure rod 9, when all the traction belts 7 outside the pressure rod 9 are released, the slide bar 10 can be popped out and reset, thereby prompting the protrusion 16 to reset, specifically, when the protrusion 16 is reset, the side of the protrusion 16 away from the extrusion surface 1601 will be in contact with the positioning strip 15 in the process of reverse rotation of the rotating disc 11 driven by the sleeve 12, thereby preventing the rotating disc 11 from continuing to rotate, at this time, the traction belt 7 can be wound and stored as the sleeve 12 continues to rotate reversely.

[0048] In summary, the structure can reversely wind the traction belt 7 in the process of the pressure rod 9 being in contact with the traction belt 7 and the sleeve 12 being rotated forward, thereby being able to pull out the sampling assembly from the water surface and drive the sampling assembly to move upward, then, in the process of the sleeve 12 being rotated forward and releasing the traction belt 7 outside the pressure rod 9, the sleeve 12 can continue to drive the rotating disc 11 to rotate through the cooperation of the slope 1702 on the slide bar 17 and the clamping groove 1202, when the protrusion 16 that pops out cooperates with the positioning strip 15, the rotating disc 11 stops rotating, at this time, the slide bar 17 will be extruded out of the clamping groove 1202, thereby enabling the sleeve 12 to rotate alone relative to the rotating disc 11, thereby being beneficial to winding and storing the traction belt 7.

[0049] The cantilever 2 can be fixed with the control box 101 or the stand column 1 during installation, and the sling 3 is fixed between the top of the stand column 1 and the end of the cantilever 2 to keep the cantilever 2 stable.

Through the structure, the sleeve 12 can be rotated by the rotating shaft 4, and the sleeve 12 can move relative to the rotating shaft 4. One end of the rotating shaft 4 and the screw rod 2011 extends into the control box 101 and is driven to rotate by two motors arranged in the control box 101. A boom is rotationally connected to the end of the rotating shaft 4 away from the control box 101, and the boom is fixedly connected with the cantilever 2.
