[0030] Please refer to Figures 1-5The utility model provides a technical scheme: a water quality monitoring storage device, including container 1, block 2, vertical rod 3, drawstring 4, gravity block 5 and support 6, the lower end wall of container 1 is equipped with opening, the upper end wall of container 1 is equipped with round hole, block 2 is located in container 1 and blocks the opening, block 2 can float in water, vertical rod 3 is fixed in block 2, the upper portion of vertical rod 3 is slidably fitted in round hole, the hole channel 31 in vertical rod 3 is connected with the outer surface of vertical rod 3 and is located in round hole, the lower end of hole channel 31 is connected with the outer surface of the lower end of vertical rod 3, gravity block 5 is hung on block 2 through drawstring 4, support 6 is fixed on container 1, and the lower end of support 6 is located on the lower side of gravity block 5.

[0031] The utility model discloses a water quality monitoring storage device in initial state, support 6 is supported on the operation platform, block 2 is supported on the lower end wall of container 1 and blocks the opening. Gravity block 5 is hung on the lower side of block 2 through drawstring 4, and gravity block 5 provides the downward tension to block 2, to make block 2 press tightly on the lower end wall of container 1, the upper end of hole channel 31 is located in round hole, and the upper end of hole channel 31 is blocked by the hole wall of round hole.

[0032] When needing to fill the water quality monitoring storage device of the utility model with water sample, the water quality monitoring storage device of the utility model is carried to the water area needing sampling, one hand of the operator holds gravity block 5, the other hand holds the upper end of container 1, and makes drawstring 4 in the relaxed state. Then container 1 is put into water and gradually moves down, because block 2 can float in water, that is, the overall average density of block 2 is less than the density of water, when container 1 is put into water, block 2 can float on the water surface, in the process of moving down, the lower end wall of container 1 will be separated from block 2, and water sample enters container 1 from the opening. When the water sample in container 1 reaches a certain amount, the operator releases gravity block 5, gravity block 5 sinks downward under the action of gravity, and gravity block 5 sinks and tightens drawstring 4, block 2 is driven to move down by gravity block 5, block 2 drives vertical rod 3 to slide downward in round hole until block 2 blocks the opening again, at this time, the inner cavity of container 1 can be in a closed state, and then the water quality monitoring storage device of the utility model can be removed from water.

[0033] When the container 1 is placed in water, the blocking block 2 can float on the water surface, and the container 1 can be separated from the lower end wall of the container 1 by moving the container 1 downward, that is, the opening can be opened by the buoyancy of water; when the water sample in the container 1 reaches a certain amount, the operator releases the gravity block 5, and the opening can be automatically closed, and the inner cavity of the container 1 can be in a closed state. It is relatively convenient to open the opening of the water quality monitoring storage device and close the opening of the water quality monitoring storage device.

[0034] During the downward movement of the container 1, the container 1 can also move downward relative to the vertical rod 3, and after the container 1 moves downward relative to the vertical rod 3 by a small distance, the upper surface of the container 1 is located below the upper edge of the upper end of the hole 31, at this time, the air in the container 1 can be discharged to the outside through the hole 31, and during the process that the water sample enters the container 1 from the opening, the formation of too large negative pressure in the container 1 can be prevented, so that the water sample can enter the container 1 from the opening more smoothly. When the blocking block 2 moves downward and re-seals the opening, the upper end of the hole 31 can re-enter the circular hole, and the upper end of the hole 31 is re-sealed by the side wall of the circular hole.

[0035] When it is necessary to discharge the water sample in the container 1, the vertical rod 3 is pulled upward, the vertical rod 3 drives the buoyancy block 23 to move upward and separates from the lower end wall of the container 1, at this time, the water in the container 1 can be discharged from the opening. When the vertical rod 3 is pulled upward again, the upper edge of the upper end of the hole 31 moves to the upper side of the circular hole, so that the outside air can enter the inner cavity of the container 1 through the hole 31, and the water in the container 1 can be smoothly discharged.

[0036] In this embodiment, the water quality monitoring storage device further comprises a sealing ring 32, and the sealing ring 32 is fixedly arranged on the hole wall of the circular hole.

[0037] The sealing ring 32 can seal the gap between the vertical rod 3 and the circular hole, and can further reduce the possibility of rainwater entering the container 1.

[0038] In this embodiment, the water quality monitoring storage device further comprises a hand carrying rod 11 and a connecting portion, the hand carrying rod 11 is located above the container 1 and is arranged horizontally, and the connecting portion connects the hand carrying rod 11 and the container 1.

[0039] When the operator moves the water quality monitoring and storage device of this utility model, he can hold the handle 11 and lift it upward. The handle 11 drives the connecting part to move upward, and the connecting part drives the container 1 to move upward together with the handle 11. At this time, the water quality monitoring and storage device of this utility model can be lifted and transported.

[0040] In this embodiment: the connecting part includes a sliding rod 113 and a counterweight ring 112. There are two sliding rods 113, which are located on opposite sides of the container 1. The sliding rods 113 can slide up and down to connect the container 1. The counterweight ring 112 is fixedly connected to the lower ends of the two sliding rods 113. The two ends of the handle 11 are fixedly connected to the upper ends of the two sliding rods 113 respectively. The pull rope 4 is located in the ring hole of the counterweight ring 112.

[0041] When it is necessary to move the water quality monitoring and storage device of this utility model, the operator holds the handle 11 and lifts it upward. The handle 11 drives the sliding rod 113 to slide upward, and the sliding rod 113 drives the counterweight ring 112 to move upward until the counterweight ring 112 abuts against the lower end face of the container 1. At this time, the water quality monitoring and storage device of this utility model can be lifted and moved.

[0042] When the water quality monitoring and storage device of this utility model is placed on the operating table, with the bracket 6 supported on the operating table, the handle 11 is released. The handle 11, sliding rod 113, and counterweight ring 112 move downwards under the action of gravity until the counterweight ring 112 abuts against the upper end face of the gravity block 5. At this time, the weight of the handle 11, sliding rod 113, counterweight ring 112, and gravity block 5 all act on the pull rope 4, allowing the pull rope 4 to pull the sealing block 2 further downwards, so that the sealing block 2 can be pressed more tightly against the lower end wall of the container 1, reducing the possibility of water leaking out of the container 1 from the opening.

[0043] In this embodiment: the connecting part further includes two fixing blocks 111, both of which are fixed on the container 1 and are located on two opposite sides of the container 1 respectively; both fixing blocks 111 have through holes, which are arranged vertically, and the two sliding rods 113 are slidably engaged in the two through holes in a one-to-one correspondence.

[0044] When the handle 11 is lifted, the handle 11 drives the sliding rod 113 to slide upward in the through hole; when the handle 11 is released, the handle 11 drives the sliding rod 113 to slide downward in the through hole under the action of gravity. With this structure, the sliding rod 113 can slide up and down to connect the container 1.

[0045] In this embodiment: the upper end of the container 1 is recessed downward to form a groove, the groove is arranged perpendicular to the length direction of the handle 11, and one end of the groove is located directly below the handle 11; the water quality monitoring and storage device of this utility model also includes a slider 121 and a support rod 12, the slider 121 is slidably engaged in the groove, the lower end of the support rod 12 is fixedly connected to the slider 121, and the upper end of the support rod 12 is used to abut against the handle 11.

[0046] Before filling the water quality monitoring and storage device of this utility model with a water sample, the operator lifts the handle 11 upwards and pushes the support rod 12 directly below the handle 11. When it is necessary to move the container 1 downwards in the water, simply hold the handle 11 and press it downwards. The handle 11 can move downwards and abut against the upper end of the support rod 12, thereby enabling the container 1 to move downwards in the water, which is quite convenient when moving the container 1 downwards in the water.

[0047] After the water quality monitoring and storage device of this utility model is placed on the operating table, that is, after the bracket 6 is supported on the operating table, the operator pushes the support rod 12 so that the upper end of the support rod 12 is separated from the handle 11. At this time, the handle 11, the sliding rod 113 and the counterweight ring 112 can move downward under the action of gravity. The counterweight ring 112 can be supported on the gravity block 5, and one side of the support rod 12 abuts against the handle 11.

[0048] In this embodiment, the opening size of the slide groove is smaller than the cavity size; specifically, the cross-section of the slide groove is a dovetail shape, smaller at the top and larger at the bottom. This structure prevents the slider 121 from detaching upwards from the slide groove.

[0049] In this embodiment: the water quality monitoring and storage device of the present invention further includes a spring 122, one end of which is connected to the side wall of the chute and the other end is connected to the slider 121.

[0050] When the counterweight ring 112 can be supported on the gravity block 5, and when one side of the support rod 12 abuts against the handle 11, the spring 122 is in a compressed state.

[0051] After the operator lifts the handle 11 upwards, the slider 121 slides to directly below the handle 11 under the elastic force of the spring 122. At this time, the support rod 12 is located directly below the handle 11. After the operator lifts the handle 11 upwards, the spring 122 can automatically push the support rod 12 to directly below the handle 11, making it easier to move the support rod 12 to directly below the handle 11.

[0052] In this embodiment: the support 6 includes two telescopic rods, both of which are structures that can extend and retract along their axial direction, and the upper ends of the two telescopic rods are fixedly connected to the outer wall of the container 1.

[0053] When filling the water quality monitoring and storage device of this utility model with water samples, since the depth of each sampling point varies, the operator can retract the telescopic rod partially when filling the water sample at a shallower sampling point, so as to easily place the opening of container 1 into the water. This improves the flexibility of using the water quality monitoring and storage device of this utility model.

[0054] In this embodiment: the telescopic rod includes a tube body 62, an inner rod 61, and a bolt 63. The upper end of the inner rod 61 is fixedly connected to the outer wall of the container 1, and the lower end of the inner rod 61 is located inside the tube body 62. The inner rod 61 cooperates with the inner cavity of the tube body 62. A screw hole is provided on the side wall of the tube body 62. The screw-in end of the bolt 63 is screwed into the screw hole and abuts against the inner rod 61.

[0055] In the initial state, the bolt 63 of the water quality monitoring and storage device of this utility model is screwed into the screw hole, and the screw-in end of the bolt 63 abuts against the inner rod 61.

[0056] When the bolt 63 is unscrewed from the screw hole, the screw-in end of the bolt 63 disengages from the inner rod 61. At this point, the inner rod 61 can slide within the inner cavity of the tube body 62 to adjust the length of the telescopic rod. With this structure, the telescopic rod is capable of extending and retracting along its axial direction.

[0057] In this embodiment: the sealing block 2 includes a buoyancy block 23, a plate 22, and a rubber pad 21. The buoyancy block 23 is fixedly connected to the lower end of the sliding rod 113, and the buoyancy block can be made of foam plastic. The upper end of the plate 22 is fixedly connected to the buoyancy block 23, and the lower end of the plate 22 is bonded with the rubber pad 21. The buoyancy block 23 can drive the plate 22 and the rubber pad 21 to float in the water.

[0058] During the process of lowering the container 1 into the water, the lower wall of the container 1 detaches from the rubber pad 21. Since the buoyancy block 23 drives the plate 22 and the rubber pad 21 to float in the water, that is, the average density of the combined structure of the buoyancy block 23, the plate 22 and the rubber pad 21 is less than the density of water. Therefore, when the container 1 is placed in the water, the buoyancy block 23, the plate 22 and the rubber pad 21 can float on the water surface.

[0059] When the operator releases the gravity block 5, the gravity block 5 sinks and tightens the pull rope 4. The gravity block 5 causes the buoyancy block 23, the plate 22, and the rubber pad 21 to move downwards until the rubber pad 21 abuts against the lower wall of the container 1, at which point the rubber pad 21 can reseal the opening. With this structure, the sealing block 2 can be supported on the lower wall of the container 1 and seal the opening.

[0060] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the spirit and scope of the technical solutions of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
