DETAILED DESCRIPTION

[0023] The utility model is further described in detail below in conjunction with the accompanying drawings.

[0024] Example:

[0025] Reference Figures 1 to 5 The utility model discloses an environmental detection water sampling device, comprising a top plate 1 and a plurality of sampling shells 2 located below the top plate 1, wherein the plurality of sampling shells 2 are evenly arranged from top to bottom. The top of the sampling shell 2 is fixedly connected to two connecting rods 3, and the two connecting rods 3 located at the top are fixedly connected to the top plate 1 (such as Figure 1 shown).

[0026] A filter screen 4 is fixedly provided on the upper half of the side wall of the sampling shell 2, a rotating plate 5 is hinged on the inner wall of the sampling shell 2, the rotating plate 5 is in contact with the side wall of the sampling shell 2, and the rotating plate 5 covers the corresponding filter screen 4, an opening portion 6 is provided on one side of the rotating plate 5, a cleaning portion 7 is provided on the outer side of the sampling shell 2, a drain pipe 8 is fixedly provided on the lower half of one side of the sampling shell 2, and a connecting portion 9 is provided between two adjacent sampling shells 2.

[0027] In this embodiment, the two opposite side walls of the filter screen 4 are coplanar with the outer wall and the inner wall of the sampling shell 2. When the rotating plate 5 shields the filter screen 4, water outside the sampling shell 2 cannot pass through the rotating plate 5 and enter the sampling shell 2. The drain pipe 8 is opened and closed by a valve control, and in the initial state, the drain pipe 8 is in a closed state.

[0028] In a further preferred embodiment of the present invention, Figure 2 As shown, the opening portion 6 includes two springs 61 fixedly connected to the top of the top plate 1, and the top ends of the two springs 61 are commonly fixedly connected to an adjusting plate 62. A vertical rod 63 is slidably penetrated through the top of the sampling shell 2. The vertical rod 63 located at the top slides through the top plate 1 and is fixedly connected to the adjusting plate 62. The outer peripheral surface of the vertical rod 63 is hinged with a linkage rod 64 located in the corresponding sampling shell 2, and the end of the linkage rod 64 away from the vertical rod 63 is hinged to the corresponding rotating plate 5.

[0029] In this embodiment, the vertical rod 63 is a round rod, and the spring 61 is always in a compressed state, so the rotating plate 5 can fit tightly against the inner wall of the sampling shell 2, thereby improving the water-proof effect at this time.

[0030] When sampling water, the device is inserted into the water, and the sampling shell 2 is submerged in the water. The adjusting plate 62 is pressed to make the adjusting plate 62 move downward relative to the top plate 1, and the spring 61 is further compressed, and the adjusting plate 62 drives the vertical rod 63 to move downward, and the vertical rod 63 drives the linkage rod 64 to move, and the linkage rod 64 drives the rotating plate 5 to rotate, so that the inner side of the filter screen 4 is exposed, and the external water can pass through the filter screen 4 and enter the sampling shell 2.

[0031] The movement of the uppermost vertical rod 63 can be transmitted to each vertical rod 63 below through the connecting portion 9, so that the rotating plates 5 in each sampling shell 2 rotate synchronously.

[0032] In a further preferred embodiment of the present invention, Figure 2 and Figure 3 As shown, the cleaning part 7 includes two side plates 71 fixedly connected to the side walls of the sampling shell 2, a lead screw 72 is provided on one side of the sampling shell 2, the lead screw 72 rotates through the corresponding two side plates 71, a motor 73 is fixedly connected to the bottom of the top plate 1, the lead screw 72 located at the top is transmission-connected to the output end of the motor 73, a screw block 74 is threadedly connected to the outer peripheral surface of the lead screw 72, and a brush plate 75 is fixedly connected to the side of the screw block 74 close to the filter screen 4.

[0033] In this embodiment, the output end of the motor 73 can rotate forward and reverse. The motor 73 drives the corresponding lead screw 72 to rotate, the lead screw 72 drives the screw block 74 to move vertically, the screw block 74 drives the brush plate 75 to move, and the brush plate 75 brushes the surface of the filter screen 4 to brush off the impurities attached to the surface of the filter screen 4, ensuring that water can normally pass through the filter screen 4 into the sampling shell 2. The working state of the motor 73 is intermittent forward and reverse rotation, so the brush plate 75 will reciprocate up and down to pass through the filter screen 4, improving the cleaning effect of the filter screen 4.

[0034] When the uppermost lead screw 72 rotates, the lead screws 72 below are driven to rotate synchronously through the connecting portion 9, so that each filter screen 4 is cleaned.

[0035] After sampling is completed, the adjusting plate 62 is loosened, and the adjusting plate 62 rises under the restoring force of the spring 61, and the rotating plate 5 covers the filter screen 4. Then the device is taken out, the corresponding drain pipe 8 is opened, and the water sample in the corresponding sampling shell 2 is collected for detection.

[0036] In a further preferred embodiment of the present invention, Figure 4 and Figure 5 As shown, the connecting portion 9 includes a threaded sleeve 91, which is threadedly connected to the outer peripheral side of two adjacent vertical rods 63, and the corresponding two connecting rods 3 are fixedly connected to the bottom surface of the corresponding sampling shell 2 by bolts, and the top ends of the corresponding plurality of lead screws 72 are fixedly connected with rectangular blocks 92, and the bottom ends of the lead screws 72 are provided with rectangular grooves 93, and the rectangular blocks 92 are slidably inserted into the corresponding rectangular grooves 93.

[0037] In this embodiment, when the connecting rod 3 is fitted with the bottom of the corresponding sampling shell 2, the corresponding two vertical rods 63 are fitted, the corresponding rectangular block 92 is completely inserted into the corresponding rectangular groove 93, and therefore the corresponding two lead screws 72 are also fitted (such as Figure 4 shown).

[0038] When installing the sampling shell 2, first align the rectangular block 92 and the rectangular slot 93 and insert them. At this time, the top lead screw 72 can drive the other lead screws 72 to rotate synchronously when it rotates. Then fix the connecting rod 3 with bolts, and finally rotate the threaded sleeve 91 so that the corresponding two vertical rods 63 are partially located in the threaded sleeve 91. Therefore, when the top vertical rod 63 moves vertically, it can drive the other vertical rods 63 to move vertically. When disassembling the sampling shell 2, rotate the threaded sleeve 91 in the opposite direction so that the threaded sleeve 91 is completely located on the outer peripheral side of one of the vertical rods 63, and then remove the bolts.

[0039] The two adjacent sampling shells 2 are detachably arranged, and the two connected sampling shells 2 can be separated when transporting the device, which is convenient for transportation, and the number of assembled sampling shells 2 can be adjusted according to the depth of the water area.

[0040] In a further preferred embodiment of the present invention, Figure 1 As shown, a guide rod 76 is fixedly connected between the two corresponding side plates 71 , and the screw block 74 is slidably connected to the corresponding guide rod 76 .

[0041] In this embodiment, the guide rod 76 limits the screw block 74 so that the screw block 74 can only move vertically and will not rotate with the lead screw 72 .

[0042] In a further preferred embodiment of the present invention, Figure 1 As shown, upper rods 10 are fixedly connected to opposite sides of the adjustment plate 62 , and two lower rods 11 are fixedly connected to the top of the top plate 1 . The lower rods 11 are L-shaped, and the horizontal sections of the lower rods 11 are located directly below the corresponding upper rods 10 .

[0043] In this embodiment, when pressing the adjustment plate 62, the upper rod 10 and the corresponding lower rod 11 are held tightly, so that the upper rod 10 moves downward relative to the lower rod 11, thereby achieving the effect of pressing the adjustment plate 62, which is more convenient and labor-saving.

[0044] The embodiments of this specific implementation method are all preferred embodiments of the utility model, and are not intended to limit the protection scope of the utility model. Therefore, all equivalent changes made based on the structure, shape, and principle of the utility model should be included in the protection scope of the utility model.
