[0002] Water quality monitoring is the process of monitoring and measuring the types, concentrations, and changing trends of pollutants in water bodies to evaluate water quality. The monitoring scope is very broad, encompassing both unpolluted and polluted natural waters and various industrial wastewaters. Key monitoring items can be divided into two categories: one is comprehensive indicators reflecting water quality, such as temperature, color, turbidity, pH, conductivity, suspended solids, dissolved oxygen, chemical oxygen demand (COD), and biochemical oxygen demand (BOD); the other is the presence of toxic substances, such as phenol, cyanide, arsenic, lead, chromium, cadmium, mercury, and organic pesticides. In addition to the aforementioned monitoring items, flow velocity and flow measurement are sometimes necessary to objectively assess the quality of river and ocean water.

DETAILED DESCRIPTION

[0034] The technical solutions of the present invention will be clearly and completely described below in conjunction with the embodiments. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example

[0036] See also Figure 1 - Figure 9 As shown, a water sampling assembly for a surface water quality monitoring device includes a box body 1, a partition 2 is provided inside the box body 1, and a telescopic mechanism 3 is provided on the upper surface of the partition 2. The telescopic mechanism 3 includes a main movable plate 301, a C-shaped slider 302 is provided at the rear right end of the main movable plate 301, a first auxiliary movable plate 304 is movably connected inside the C-shaped slider 302, and the rear right end of the first auxiliary movable plate 304 is movably connected to the second auxiliary movable plate 305 through the C-shaped slider 302, and the second auxiliary movable plate 305 is provided with five groups, and the five groups of second auxiliary movable plates 305 are connected by the C-shaped slider 302. The rear right end of the last group of second auxiliary movable plates 305 is slidably connected to the inner rear wall of the box body 1 through the square slider 306. The main movable plate 301, the first auxiliary movable plate 304 and the second auxiliary movable plate 305 are all slidably installed inside the box body 1;

[0037] It should be noted that, first, the main movable plate 301 is manually pushed to the left, so that the main movable plate 301 moves to the left and out of the box body 1. At this time, the main movable plate 301 moves to the left and the C-shaped slider 302 connected to its rear side slides to the left on the first sub-movable plate 304. When the C-shaped slider 302 moves to the leftmost end of the first sub-movable plate 304 and engages with the first sub-movable plate 304, when the main movable plate 301 continues to move to the left, the first sub-movable plate 304 will be driven to move to the left through the C-shaped slider 302. Similarly, when the main movable plate 301 continues to move to the left, the second sub-movable plate 305 can be driven to move to the left through the C-shaped slider 302 on the first sub-movable plate 304, thereby achieving the extension effect of the movable plate.

[0038] A traction mechanism 4 is provided above the main movable plate 301, the first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305. The traction mechanism 4 includes a mounting plate 401, and the mounting plate 401 is provided on the left inner wall of the box body 1. An automatic retractable cable reel 402 is provided on the upper surface of the mounting plate 401. A traction rope 403 is wound around the circumferential surface of the automatic retractable cable reel 402. The left end of the traction rope 403 passes through the left side of the box body 1 and is connected to a hook 404. The hook 404 is connected to a fixing ring 405, and the fixing ring 405 is provided at the left end of the upper surface of the main movable plate 301.

[0039] It should be noted that when the main movable panel 301, the first auxiliary movable panel 304, and the second auxiliary movable panel 305 move to the left, the traction ropes 403 connected thereto are all in a stretched state, so that the traction ropes 403 can exert a pulling force on the main movable panel 301, the first auxiliary movable panel 304, and the five sets of second auxiliary movable panels 305, thereby dispersing the influence of gravity on the main movable panel 301, the first auxiliary movable panel 304, and the five sets of second auxiliary movable panels 305, reducing the pressure caused by gravity on the connection between the main movable panel 301, the first auxiliary movable panel 304, and the five sets of second auxiliary movable panels 305, and improving the stability and service life of the main movable panel 301, the first auxiliary movable panel 304, and the five sets of second auxiliary movable panels 305 during use.

[0040] A clamping mechanism 5 is provided on the left side of the automatic retractable cable reel 402, which includes an L-shaped movable plate 501, and the L-shaped movable plate 501 is movably installed on the left inner side of the box body 1 through a spring 1 502, a cross plug block 503 is provided on the right side of the upper end of the L-shaped movable plate 501, and a cross slot 504 matching the cross plug block 503 is provided on the left side of the automatic retractable cable reel 402, the left side wall of the box body 1 is threadedly connected to a limiting screw 505, and the right end of the limiting screw 505 abuts against the left side wall of the L-shaped movable plate 501, the left ends of the upper surfaces of the main movable plate 301, the first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305 are all provided with L-shaped abutting blocks 13, and the right side of the L-shaped abutting block 13 abuts against the left side of the lower surface of the L-shaped movable plate 501;

[0041] At the same time, because the L-shaped abutment block 13 moves to the left and no longer abuts against the L-shaped movable plate 501, the L-shaped movable plate 501 and the cross plug block 503 move to the left through the spring 1 502, causing the automatic retractable cable reel 402 to lose its limit fixation. The automatic retractable cable drum 402 is fixed to the left side of the main movable plate 301, the first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305, so that the cable drum 403 is always in a straight state. At the same time, it does not affect the horizontal movement of the main movable plate 301, the first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305 to the left. After the main movable plate 301, the first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305 are extended, the limiting screw 505 on the left side of the corresponding L-shaped movable plate 501 is rotated to make the limiting screw 505 move to the right, pushing the L-shaped movable plate 501 and the cross plug block 503 to move to the right, so that the cross plug block 503 is inserted into the cross slot 504, fixing the automatic retractable cable drum 402, and avoiding the unwinding of the automatic retractable cable drum 402 during water collection, which affects the use of the cable drum 403.

[0042] The first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305 are both provided with a limiting mechanism 7 inside the left side. The limiting mechanism 7 includes a vertical plate 701, which is movably installed in the interior of the first auxiliary movable plate 304. The upper and lower ends of the vertical plate 701 are provided with connecting rods 702, and the rear ends of the two connecting rods 702 are provided with blocking blocks 703. The rear ends of the two blocking blocks 703 are inserted into the interior of the C-shaped slider 302. The circumferential surfaces of the two connecting rods 702 are sleeved with springs 704. The rear end of the spring 704 is connected to the blocking block 703, and the front end of the spring 704 is connected to the interior of the first auxiliary movable plate 304. The upper and lower ends of the first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305 are both provided with sliding grooves 303. The rear end of the C-shaped slider 302 is slidably installed in the interior of the sliding grooves 303. The setting of the sliding grooves 303 provides sliding space for the C-shaped slider 302, so that the C-shaped slider 302 can smoothly move left and right horizontally;

[0043] It should be noted that the rear end of the right side of the block 703 is designed to be arc-shaped, so that when the C-shaped slider 302 moves to contact the block 703, it can first squeeze the block 703 forward, and then when the C-shaped slider 302 moves to the leftmost end of the slide groove 303, the block 703 moves backward under the action of the second spring 704, so as to be inserted into the inside of the C-shaped slider 302 and limit the C-shaped slider 302 to fix it, so that the main movable plate 301 can be connected to the first sub-movable plate 304 through the C-shaped slider 302, so that the first sub-movable plate 304 can be connected to the second sub-movable plate 305 through the C-shaped slider 302, and the second sub-movable plate 305 at the front end can also be connected to the second sub-movable plate 305 at the rear side through the C-shaped slider 302.

[0044] The first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305 are both provided with a squeezing mechanism 8, which includes a left and right movable plate 801, which is movably mounted on the inside of the first auxiliary movable plate 304, and a ring-shaped mounting block 802 is provided on the surface of the left side of the left and right movable plate 801, and a spring three 803 is provided on the left wall of the ring-shaped mounting block 802, and the left end of the spring three 803 is connected to the inside of the first auxiliary movable plate 304, and an arc-shaped protrusion 804 is provided on the front of the left end of the left and right movable plate 801, and the arc-shaped protrusion 804 is provided on the right side of the vertical plate 701, and the left end of the rear side of the vertical plate 701 is an arc-shaped design, and the right side wall of the box body 1 is provided with a storage slot two 14, and the storage slot two 14 is provided with six, and the six storage slots two 14 are respectively provided on the left sides of the six left and right movable plates 801;

[0045] When the left and right movable plates 801 are pushed to the left, the left and right movable plates 801 move to the left. When the left end of the left and right movable plates 801 moves to the rear side of the vertical plate 701, the arc-shaped protrusion 804 pushes the vertical plate 701 forward, so that the vertical plate 701 drives the block 703 to move out of the C-shaped slider 302 through the connecting rod 702, so that the C-shaped slider 302 loses its fixing effect, thereby disconnecting the two second auxiliary movable plates 305 or disconnecting the first auxiliary movable plate 304 and the second auxiliary movable plate 305 or disconnecting the main movable plate 301 and the first auxiliary movable plate 304.

[0046] The six storage slots 14 are each provided with a pushing mechanism 9, and the six groups of pushing mechanisms 9 are respectively arranged below the right end of the first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305. The pushing mechanism 9 includes a lower pressing plate 901, and the lower end of the lower pressing plate 901 is movably mounted on the inside of the partition 2 through a spring four 902. The right lower end of the lower pressing plate 901 is movably connected to the upper moving plate 904 through a hinge rod 903. The middle of the hinge rod 903 is rotatably mounted on the inside of the partition 2 through a fulcrum. The upper moving plate 904 is movably mounted on the inside of the box body 1, and the upper end of the upper moving plate 904 is located below the storage slot 14. The left and right sides of the upper end of the lower pressing plate 901 are both arc-shaped. The first auxiliary movable plate 304 and the five groups of second auxiliary movable plates 305 are both provided with a storage slot 11 that matches the lower pressing plate 901 at the lower end of the right side.

[0047] It should be noted that when the first auxiliary movable plate 304 is stored back into the box body 1, the first auxiliary movable plate 304 moves to the right into the box body 1. When the right end of the first auxiliary movable plate 304 contacts the lower pressure plate 901, the lower pressure plate 901 can be squeezed downward, so that the lower pressure plate 901 drives the upper moving plate 904 to move upward through the hinge rod 903, so that the upper end of the upper moving plate 904 moves into the interior of the storage slot 2 14. At this time, the right end of the left and right movable plate 801 will abut against the upper moving plate 904. Then, as the first auxiliary movable plate 304 continues to move to the right, the left and right movable plates 801 will move to the left, so that the arc-shaped protrusion 804 pushes The movable vertical plate 701 moves forward, causing the C-shaped slider 302 to lose its fixing effect, disconnecting the main movable plate 301 and the first sub-movable plate 304. At this time, the first sub-movable plate 304 is completely moved into the box body 1, and the lower pressure plate 901 moves upward under the action of spring four 902 and is inserted into the storage groove 11 of the first sub-movable plate 304. At the same time, the upper plate 904 is reset downward, leaving the storage groove 2 14 empty, leaving space for the right end of the left and right movable plate 801 to connect. At this time, the left and right movable plate 801 moves to the right to its initial position under the action of spring three 803, so that the arc-shaped protrusion 804 no longer abuts against the vertical plate 701.

[0048] A water sampling mechanism 6 is provided below the main movable plate 301. The water sampling mechanism 6 includes a motor 601, and the motor 601 is provided inside the right end of the main movable plate 301. The power output end of the motor 601 is transmission-connected to a winding shaft 602. The circumferential surface of the winding shaft 602 is connected to a water quality sampler 603 through a pull rope. A positioning wheel 604 is provided on the lower surface of the left end of the main movable plate 301, and the left end of the pull rope is connected to the positioning wheel 604 through rope transmission. A movable groove 12 is provided inside the front end of the partition 2, and the width of the movable groove 12 is greater than the diameter of the water quality sampler 603. The setting of the movable groove 12 enables the main movable plate 301 to drive the water sampling mechanism 6 to move horizontally left and right smoothly. A sealing door 10 is provided on the left side wall of the box body 1, and the sealing door 10 is located to the right of the water quality sampler 603. The setting of the sealing door 10 can close the left side of the box body 1 when this device is not in use.

[0049] When the present invention is in use, when sampling surface water is required, the box body 1 is carried to the riverside, and then the main movable plate 301 is moved to the left, so that the main movable plate 301 is moved out of the box body 1. When the main movable plate 301 moves to the left, so that its corresponding L-shaped movable plate 501 loses its abutment limit, the L-shaped movable plate 501 drives the cross plug 503 to move out of the cross slot 504 through the spring 1 502, so that the main movable plate 301 moves smoothly to the left, while the traction rope 403 above it is always in an unwound and straightened state;

[0050] When the main movable plate 301 drives the C-shaped slider 302 to move leftward to the left end of the inner groove 303 of the first auxiliary movable plate 304, the clamping block 703 is clamped in the inside of the C-shaped slider 302 by the spring 2 704, so that the main movable plate 301 and the first auxiliary movable plate 304 are connected together. At this time, when the main movable plate 301 continues to move leftward, it can drive the first auxiliary movable plate 304 to move leftward. Similarly, when the first auxiliary movable plate 304 is connected to the second auxiliary movable plate 305 through the C-shaped slider 302, it can drive the second auxiliary movable plate 30 5 is moved to the left out of the box body 1. When the water quality sampler 603 under the main movable plate 301 moves to the appropriate water sampling point, the second auxiliary movable plate 305 stops moving toward the outside of the box body 1. At this time, all the limiting screws 505 in front of the second auxiliary movable plate 305 are rotated so that the limiting screws 505 drive the corresponding L-shaped movable plate 501 to move to the right. The cross plug 503 is inserted into the cross slot 504 to limit and fix the corresponding automatic retractable reel 402 to prevent the automatic retractable reel 402 from rotating and affecting the effect of the traction rope 403.

[0051] Then, the motor 601 is started, and the motor 601 drives the winding shaft 602 to rotate, so that the winding shaft 602 is unwound, and the water quality sampler 603 is moved downward into the water, and the water quality sampler 603 smoothly performs the water sampling work.
