Description

Technical Field

[0001] This invention relates to the field of water sampling technology, and in particular to a water quality testing device with a blockage-clearing structure. Background Technology

[0002] Sampling and comparing water bodies allows for timely understanding of water quality, thereby enabling water monitoring. When sampling water, it is necessary to sample water from different areas. In complex environments, water sources may be located in areas that are difficult to collect, requiring the use of other tools. After a long period of operation, the pipe openings need to be cleaned to prevent blockages.

[0003] The sampling equipment currently in use has the following drawbacks:

[0004] 1. Existing sampling equipment requires the use of a drop line to drop the sampling tube to the sampling position and to sample the required location by controlling the depth. This is not convenient for multiple individually controlled sampling groups underwater, and it is not conducive to maintaining power supply underwater and sampling at different depths.

[0005] 2. Existing sampling equipment is not convenient for rapid movement and precise movement and angle adjustment in water bodies;

[0006] 3. Existing sampling equipment lacks the function of quickly resetting after sampling, which is not conducive to continuous sampling and subsequent relocation and recovery. Summary of the Invention

[0012] Optionally, the control motor and the steering roller are connected by a bevel gear transmission.

[0013] Optionally, the steering jet further includes: a water passage hole, the steering roller having a water passage hole on its exterior; a jet hole, the steering jet having a jet hole on its exterior, the jet hole communicating with the water passage hole; and a channel inside the movable float connecting the water pump and the water passage hole.

[0015] Optionally, the control base further includes: a lead screw, which is rotatably mounted on the upper part of the control base; a trapezoidal block, which is slidably mounted on the upper part of the control base and threadedly connected to the lead screw; a micro motor, which is fixedly mounted on the top of the control base and connected to the lead screw via a bevel gear transmission; a bidirectional pump, which is fixedly mounted on one end of the top of the control base and connected to the bottom side of the control base via a pipe; both the micro motor and the bidirectional pump are covered with waterproof housings; and a docking cylinder, which is integrally mounted on the rear side of the control base.

[0016] Optionally, the sample collector includes: an intermediate cylinder, which is integrally provided at the rear center of the sample collector; the front end of the sample collector can be inserted into the rear side of the control seat; a one-way valve, which is fixedly provided at the center of the intermediate cylinder; and a filter, which is fixedly provided at the rear end of the intermediate cylinder.

[0018] The beneficial effects are as follows:

[0019] 1. The system is equipped with a take-up roller, providing a function for sampling at different depths when it is difficult to maintain power underwater. The drive motor starts to rotate the worm gear, which in turn rotates the worm wheel, which in turn rotates the linkage shaft. The linkage shaft, through a bevel gear, drives the take-up roller to rotate, thereby controlling the raising and lowering of the hoisting wire. During the lowering of the wire, the sinker descends, causing the control seat and the sampler to descend synchronously. The sampler is then placed at the sampling depth. The hexagonal piston plate generates negative pressure, drawing water from the water body through the filter and one-way valve into the sampler, thus enabling sampling. The brushes and hoisting wire maintain power supply, providing power to the underwater micro motor and bidirectional pump during the descent of the control seat and sampler.

[0020] 2. The setting of the steering roller provides precise movement and angle adjustment functions. When the water pump is started, water is directly drawn from the water body through the filter, then transported through the water passage hole to the steering roller, and then sprayed out from the spray hole to generate propulsion force, thereby driving the entire sampling equipment to move the equipment above the sampling position.

[0021] 3. The sampler is equipped with a quick reset function after sampling. The valve block can only control one set of samplers in the collecting state at a time. Therefore, different sets of samplers can be controlled to collect water samples at different depths after height adjustment. Finally, the reverse drive motor and the winding roller will retrieve the lifting wire, which can retrieve the sinker to the bottom of the moving float and complete the reset.

When unloading the wire, the sinker 6 descends, driving the control seat 7 and the sample collector 8 to descend synchronously, and throwing the sample collector 8 to the sampling depth.

[0038] The take-up roller 3 also includes: brushes 301, brushes 301 are fixedly installed on both sides of the bracket of the take-up roller 3, and brushes 301 are energized with the suspension wire 302; the suspension wire 302 is provided with a waterproof and wear-resistant coating.

[0041] The control base 7 includes: a T-shaped module 701, which is fixedly installed inside the control base 7; spring rods A702 are fixedly installed between the lower sides of the T-shaped module 701 and the control base 7; a valve block 703, with side plates 704 fixedly installed on both sides of the valve block 703, which are slidably installed outside the spring rods A702; a spring is sleeved on the spring rods A702 below the side plates 704; the top of the valve block 703 is a triangular structure; and a turning hole 7. 05. A turning hole 705 is provided through the bottom and rear side of the valve block 703; a lead screw 706 is rotatably mounted inside the upper part of the control base 7; a trapezoidal block 707 is slidably mounted inside the upper part of the control base 7, and the trapezoidal block 707 is threadedly connected to the lead screw 706; a micro motor 708 is fixedly mounted on the top of the control base 7, and the micro motor 708 is connected to the lead screw 706 by a bevel gear transmission; a bidirectional pump 709 is located on the top of the control base 7. A bidirectional pump 709 is fixedly installed at one end, and a pipe is provided connecting the bidirectional pump 709 to the bottom side of the control base 7; both the micro motor 708 and the bidirectional pump 709 are equipped with waterproof shells; a docking cylinder 710 is integrally installed on the rear side of the control base 7; when sampling is required, first determine the sampler 8 to be used, start the micro motor 708, which, in conjunction with the bevel gear, drives the lead screw 706 to rotate, and uses the lead screw 706 to provide a driving effect to move the trapezoidal block 707. The movement of trapezoidal block 707 compresses a set of valve blocks 703, pressing the valve blocks 703 downwards. When the valve blocks 703 descend, they connect the turning hole 705 with the docking cylinder 710. At this time, the bidirectional pump 709 is activated to draw air outwards, which can expel the air in the front cavity inside the sampler 8. Then, the hexagonal piston plate 804 moves forward, and a negative pressure is generated on the rear side of the hexagonal piston plate 804, which draws water from the water body through the filter 803 and the one-way valve 802 into the sampler 8, thus achieving sampling.

[0042] The sample collector 8 includes: an intermediate cylinder 801, integrally formed at the rear center of the sample collector 8; the front end of the sample collector 8 can be inserted into the rear side of the control seat 7; a one-way valve 802, fixedly installed in the middle of the intermediate cylinder 801; a filter 803, fixedly installed at the rear end of the intermediate cylinder 801; a hexagonal piston plate 804, slidingly installed inside the sample collector 8; and a rotating sleeve 805, rotatably installed on the outside of the intermediate cylinder 801. 805, the outer part of the rotating sleeve 805 is designed as a hand-rubbing structure; the bottom of the rotating sleeve 805 has a rotating hole 806; the locking block 807 has a spring rod B808 fixedly installed on the top of the locking block 807, and the spring rod B808 is slidably connected to the rear side of the sample collector 8; the top of the rotating sleeve 805 has a groove that matches the locking block 807; the top of the intermediate cylinder 801 has a water outlet hole 809; by rotating the rotating sleeve 805 to align the rotating hole 806 and the water outlet hole 809, the sample can be poured out for application.

[0043] The specific usage and function of this embodiment: In this invention, when in use, the movable float 1 needs to be placed on the water surface, and then the water pump 101 is started to directly draw water from the water body through the filter 102, and then transport it through the water passage hole 502 to the steering roller 501, and then spray it out from the spray hole 503 to generate propulsion force, thereby driving the entire sampling device to move and move the device above the sampling position.

[0044] When it is time to lay out the wire, the drive motor 201 is started to drive the worm gear 202 to rotate, the worm gear 202 drives the worm wheel 204 to rotate, the worm wheel 204 drives the linkage shaft 203 to rotate, and the linkage shaft 203 drives the take-up roller 3 to rotate through the bevel gear, thereby realizing the control of the laying out of the suspended wire 302. When laying out the wire, the sinker 6 descends, driving the control seat 7 and the sampler 8 to descend synchronously, and throwing the sampler 8 to the sampling depth.

[0045] During the descent of the control seat 7 and the sampler 8, the brush 301 and the lifting wire 302 can maintain power transmission. A mobile power supply is set up above the movable float 1 in advance to work with the brush 301 to provide power, ensuring power supply for the underwater micro motor 708 and the bidirectional pump 709.

[0046] Example 2:

[0047] Based on Example 1, such as Figure 1-6As shown, when sampling needs to be controlled, first determine the sampler 8 to be used, start the micro motor 708, and drive the lead screw 706 to rotate in conjunction with the bevel gear. The lead screw 706 provides a driving effect to move the trapezoidal block 707. The movement of the trapezoidal block 707 squeezes a set of valve blocks 703, pressing the valve blocks 703 downward. When the valve blocks 703 descend, they connect the turning hole 705 with the docking cylinder 710. At this time, the bidirectional pump 709 is started to draw air outward, which can expel the air in the front cavity inside the sampler 8. Then the hexagonal piston plate 804 moves forward, and a negative pressure is generated on the rear side of the hexagonal piston plate 804 to draw water from the water body through the filter 803 and the one-way valve 802 into the sampler 8, thus realizing sampling.

[0048] The valve block 703 can only control one set of sample collectors 8 to be in the collection state at a time, so it can control different sets of sample collectors 8 to collect water samples at different depths after height adjustment; finally, the reverse drive motor 201 and the winding roller 3 will retrieve the lifting wire 302, which can retrieve the sinker 6 to the bottom of the moving float 1; rotating the rotating sleeve 805 will align the rotating hole 806 and the water outlet 809, and the sample can be poured out.

[0049] Example 3:

[0050] Based on Example 1, such as Figure 5-6 As shown, long-term unidirectional filtration of filter 803 will cause the accumulation of aquatic organisms and aquatic debris on the outside, leading to blockage and affecting sampling;

[0051] A filter screen is installed on the outside of the bidirectional pump 709. If reverse unclogging is required, the bidirectional pump 709 is reversed to draw water into the sampler 8. Then, the hexagonal piston plate 804 is pushed back to discharge the drawn water and impact the filter 803 in the reverse direction, washing away the debris outside the filter 803. By repeatedly driving the hexagonal piston plate 804 to reciprocate multiple times, unclogging can be achieved.
