[0002] Metal pipe fittings are important components in the connecting pipelines of modern industrial equipment. They are widely used because of their high temperature resistance, low temperature resistance, aging resistance, and corrosion resistance.

The lower end of the winding mechanism is connected to multiple sampling mechanisms through ropes, which can simultaneously take water from the same deep layer, facilitate the detection of water bodies in multiple directions, reduce the error of experimental data, improve the accuracy of detection data, and improve the overall effectiveness and practicality of the device.

[0004] The above-mentioned existing technical solutions have the following shortcomings: the water intake of the sampling system of the water intake of each water quality automatic station is set within the range of 0.5-1m underwater.

When the device is in use, it is not easy to ensure that the water inlet position of the sampling device can always be below the water level line as the water level changes. Therefore, there is room for improvement. Summary of the invention

[0032] Embodiment 1

[0033] In order to solve the problem that the existing retractable bottom-sinking water quality automatic sampling device suitable for different hydrological conditions is not easy to adjust the water inlet position in real time according to the water level change, the following scheme is disclosed, specifically as follows: Figure 1 , Figure 2 , 7 As shown:

[0034] A retractable bottom-sinking automatic water quality sampling system suitable for different hydrological conditions comprises a floating component 1, a plurality of slide rails 2 are uniformly penetrated inside the floating component 1, and pulleys 3 are slid inside the slide rails 2, one side of the pulley 3 is connected to the inner wall of the floating component 1, the top ends of the plurality of pulleys 3 are commonly connected to a top plate 4, and the bottom ends of the pulleys 3 are poured to the bottom of the water body through concrete, a water quality sampling system is arranged on the floating component 1, and the water quality sampling system comprises a sampling module, and one end of the sampling module is electrically connected to a flow control module;

[0035] The sampling module includes a water pump 5 arranged at the bottom center of the floating assembly 1, and a sampling tube 6 is installed at the bottom end of the water pump 5, one side of the water pump 5 is connected to an L-shaped connecting pipe 7, and one end of the L-shaped connecting pipe 7 is connected to a delivery hose 8, one end of the delivery hose 8 is connected to a sampling collection device on the shore, and the length of the delivery hose 8 is greater than the straight-line distance from the top plate 4 to the shore;

[0036] The flow control module includes a control box 10 arranged at the top center of the floating assembly 1, and a frequency converter is arranged inside the control box 10, the output end of the frequency converter is connected to the input end of the water pump 5 by telecommunication through an automatic winding mechanism 12, the input end of the frequency converter is connected to the circuit assembly on the shore through the automatic winding mechanism 12, and the automatic winding mechanism 12 of the input end of the frequency converter passes through the top of the top plate 4 to be suspended on the shore;

[0037] The floating assembly 1 includes a connecting plate 101, and a connecting frame 102 is welded to the outer edge of the connecting plate 101, and a plurality of buoys 103 are evenly sleeved on the connecting frame 102. The top of the connecting plate 101 is fixedly connected to a floating platform 104, and the outer edge of the bottom end of the floating platform 104 is connected to the outer edge of the connecting frame 102;

[0038] The floating platform 104 is in a triangular ring shape, and moves up and down along the periphery of the plurality of top plates 4 , and the outer edge of the connecting plate 101 is parallel to the sliding side of the top plates 4 .

[0039] In this embodiment, the buoyancy of the buoy 103 is utilized to drive the floating platform 104 and the connecting plate 101 to float on the water surface, and according to the tidal changes or water level changes of the water body, the pulley 3 can slide along the inner wall of the slide rail 2, thereby driving the entire floating assembly 1 to move up and down, and the restrictions of multiple slide rails 2 are utilized to prevent the floating assembly 1 from being offset and shaking to the left and right, which is conducive to stabilizing the sampling process;

[0040] The control box 10 is used to control the frequency converter to adjust the rotation frequency of the motor on the water pump 5, so that the pumping rate of the sampling tube 6 when absorbing water is changed. The sampling rate can be adjusted according to the weather conditions on site, so that the water sample flows along the sampling tube 6 into the L-shaped connecting tube 7, and then enters the delivery hose 8 to be transported to the sampling collection device on the shore.

[0041] Embodiment 2

[0042] This embodiment is different from the first embodiment. The conductor 11 is protected by the automatic winding mechanism 12, and the foldability of the automatic winding mechanism 12 is used to adapt to the lifting position change of the floating component 1 to reduce the direct contact between the conductor 11 and the water body. Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown:

[0043] An automatic winding mechanism 12 is provided on one side of the control box 10. When the floating assembly 1 is lifted up and down along the top plate 4, the automatic winding mechanism 12 automatically winds the wire 11.

[0044] The automatic winding mechanism 12 includes an L-shaped guide tube 1201 installed outside the control box 10, and the top end of the L-shaped guide tube 1201 is hinged with a folding hinge assembly, and the bottom end of the top plate 4 is fixedly connected with a top pipe 1205 at the position of the L-shaped guide tube 1201, and the top pipe 1205 is hinged with the top end of the folding hinge assembly, and the wire 11 runs through the L-shaped guide tube 1201, the folding hinge assembly and the top pipe 1205;

[0045] The folding hinge assembly includes two hinged long tubes 1202, and the outer ends of the long tubes 1202 are hinged with short tubes 1203, the top end of the upper short tube 1203 is connected to the top tube 1205, and the bottom end of the lower short tube 1203 is hinged to the L-shaped tube 1201, and the top ends of the outer sides of the long tube 1202 and the lower short tube 1203 are fixedly connected with eccentric weights 1204;

[0046] The outside of the hinge points between the L-shaped conduit 1201, the folded hinge assembly and the top pipe 1205 are all covered with a waterproof membrane.

[0047] In this embodiment, when the floating assembly 1 descends with the water level of the water body during use, the control box 10 pulls the L-shaped guide tube 1201 to descend, so that the L-shaped guide tube 1201 pulls the folding hinge assembly to stretch and deform, so that the bent and wound wire 11 is stretched, thereby adapting to the change in the position of the control box 10, and the effect of the L-shaped guide tube 1201 is used to prevent the wire 11 from directly contacting the water body, thereby improving the protection effect of the wire 11;

[0048] When the floating component 1 rises, the L-shaped tube 1201 moves synchronously. Since the outer sides of the short tube 1203 and the long tube 1202 below are provided with eccentric weight blocks 1204, the folding hinge component is automatically bent under the action of eccentric weight, so that the wire 11 is folded and rolled up to prevent the wire 11 from falling directly on the water surface. The automatic winding effect of the automatic winding mechanism 12 on the wire 11 is utilized, so that the floating component 1 will not produce sudden pulling on the wire 11 when it is raised or lowered at any time, thereby preventing the nodes at both ends of the wire 11 from breaking, and at the same time, the real-time changes of the sampling position can be used.

[0049] Embodiment 3

[0050] This embodiment is different from the first embodiment. The floating guide assembly 9 is used to guide the delivery hose 8, thereby stabilizing the stability of the water sample delivery. Figure 1 , Figure 3 , Figure 6 As shown:

The delivery hose 8 is evenly sleeved with a small buoyancy box 903 and a large buoyancy box 904, and one end of the traction rope 902 passes through the inside of the small buoyancy box 903 and the large buoyancy box 904.

[0053] There are two small pontoons 903 , and there are multiple large pontoons 904 , the number of which is greater than that of the small pontoons 903 . The bottom ends of the large pontoons 904 are fixedly connected with balance weights 905 , and the balance weights 905 and the large pontoons 904 are vertically distributed.

[0054] In this embodiment, the buoyancy of the small buoy 903 and the large buoy 904 is utilized during use to float the delivery hose 8 on the water surface, thereby preventing the delivery hose 8 from sagging to the bottom of the water body when the water sample is transported, thereby ensuring the transportation stability of the water sample. At the same time, the traction effect of the traction rope 902 is utilized to limit the position of the large buoy 904 and the small buoy 903, thereby ensuring the position stability between the large buoy 904, the small buoy 903 and the delivery hose 8, and the balance hammer 905 is utilized to further improve the stability of the large buoy 904, reduce the overturning of the large buoy 904 and others when the water body is shaking, thereby further improving the stability of the position of the delivery hose 8.
