[0006] In order to solve the above technical problems, the utility model provides a water quality sampling device to solve the problem raised in the above background technology that different detection items require water quality detection at different depths and areas, and the sampling device in the above patent is difficult to ensure that the sample will not be mixed with water quality at other depths during the process of taking out the sample after sampling the water quality, so it is difficult to ensure the purity of the test sample, which in turn affects the accuracy of the test result and has certain limitations.

[0007] The purpose and effect of the water quality sampling device of the utility model are achieved by the following specific technical means:

[0008] A water quality sampling device comprises: a buoy; the buoy adopts a conical block structure, and a through-type circular through groove structure is opened in the middle of the top of the buoy; a fixing frame of a frame structure is fixedly arranged on the top of the buoy, and a through-type circular through groove structure is opened in the middle of the top of the fixing frame, and the circular through groove in the middle of the top of the fixing frame and the circular through groove of the buoy are on the same vertical line; a connecting rod of a cylindrical structure is slidably arranged in the circular through groove in the middle of the top of the fixing frame; a through-type circular slide groove structure is opened in the middle of the connecting rod; a cylindrical structure container tube is fixedly connected to the bottom of the connecting rod, and a through-type circular through groove structure is opened in the middle of the bottom of the container tube.

[0023] The implementation of the utility model is further described in detail below in conjunction with the drawings and examples. Example

[0024] As attached Figure 1 To Attachment Figure 6 As shown:

[0025] The utility model provides a water quality sampling device, comprising: a buoy 1; the buoy 1 adopts a conical block structure, and a through-type circular through groove structure is opened in the middle of the top of the buoy 1; a fixing frame 101 of a frame structure is fixedly arranged on the top of the buoy 1, and a through-type circular through groove structure is opened in the middle of the top of the fixing frame 101, and the circular through groove in the middle of the top of the fixing frame 101 is on the same vertical line as the circular through groove of the buoy 1; a connecting rod 2 of a cylindrical structure is slidably arranged in the circular through groove in the middle of the top of the fixing frame 101; a through-type circular slide groove structure is opened in the middle of the connecting rod 2; a cylindrical structure container tube 202 is fixedly connected to the bottom of the connecting rod 2, and a through-type circular through groove structure is opened in the middle of the bottom of the container tube 202.

[0026] Among them, a cylinder 201 is fixedly arranged on the top of the connecting rod 2; a sliding rod 203 with a cylindrical structure is slidably arranged in the circular slide groove in the middle of the connecting rod 2, and the top of the sliding rod 203 is transmission-connected to the cylinder 201; a piston plate 204 with a circular plate structure is fixedly arranged on the bottom end of the sliding rod 203, and the outer wall of the piston plate 204 fits with the inner wall of the container tube 202; a bottom rod 205 with a cylindrical structure is fixedly connected to the bottom of the piston plate 204; and a blocking plate 206 with a circular plate structure is fixedly arranged on the bottom of the bottom rod 205.

[0027] The specific usage and function of this embodiment are as follows:

[0028] The cylinder 201 at the top of the connecting rod 2 is started, and the sliding rod 203 is driven by the cylinder 201 to slide upward along the circular groove inside the connecting rod 2. In this process, the piston plate 204 and the plugging plate 206 are synchronously driven to slide upward. When the piston plate 204 slides upward inside the container tube 202, negative pressure can be generated inside the container tube 202, so that water is pumped into the container tube 202 to complete the water quality sampling process. When the piston plate 204 moves to the top of the inner side of the container tube 202, the plugging plate 206 is synchronously driven by the bottom rod 205 to move to a state of contact with the bottom opening of the container tube 202, and the plugging plate 20 6 The opening at the bottom of the container tube 202 is blocked. On the one hand, it can prevent the sample inside the container tube 202 from leaking out. On the other hand, it can also prevent the water quality at different heights from mixing with the sample inside the container tube 202 during the process of raising the container tube 202, thereby affecting the accuracy of the detection result. After the sampling is completed, the reel-up roller 105 is started again to rotate in the opposite direction to reel in the connecting rope, thereby pulling the connecting rod 2 and the container tube 202 upward and resetting them through the connecting rope, and then the buoy 1 can be returned. During the return process, the cable fixed in advance on the anchor 107 can be directly pulled, and then the entire sampling process can be completed. Example

[0029] Based on Example 1, as shown in the attached Figure 1 To Attachment Figure 6 As shown:

[0030] Among them, a solar panel 102 is fixedly installed on one side of the fixed frame 101; a wind vane 103 is rotatably installed on one side of the top of the fixed frame 101; two sets of rollers 104 are rotatably installed on the top of the fixed frame 101; a cylindrical winding roller 105 is rotatably installed on one side of the fixed frame 101, and a connecting rope is wrapped around the outer side of the winding roller 105, and the connecting rope on the outer side of the winding roller 105 is fixedly connected to the top of the connecting rod 2; a motor 106 is fixedly installed on one side of the fixed frame 101, and the motor 106 is transmission-connected to the winding roller 105; a cylindrical anchor 107 is fixedly installed on the top of the buoy 1.

[0031] A power source 108 is fixedly arranged in a circular array on the outer side of the bottom of the buoy 1; and a paddle 109 is arranged on the outer side of the power source 108 in a rotational transmission connection.

[0032] The specific usage and function of this embodiment are as follows:

[0033] In the utility model, when in use, the cable is fixedly connected to the anchor 107, and then the buoy 1 is placed in the sampling water area, and the power source 108 is started to drive the blade 109 to rotate. Through the cooperation of multiple groups of power sources 108, the buoy 1 is driven to move on the water surface, so that it can move more quickly to the surface above the water where sampling is required. The solar panel 102 can power the motor 106 and the cylinder 201, and the wind vane 103 can detect the wind force and direction, and then the connecting rod 2 and the container need to be adjusted according to the sampling depth. The depth of the cylinder 202 entering the water is determined by starting the motor 106 to drive the winding roller 105 to rotate, thereby retracting and releasing the connecting rope on the outside of the winding roller 105. When it needs to be lowered, the connecting rope is prevented from loosening and loses its limiting effect on the connecting rod 2. Under the action of the connecting rod 2's own weight, the connecting rope is driven to be lowered along the top of the two sets of rollers 104, so that the connecting rod 2 slides downward along the inner side of the circular groove in the middle of the top of the buoy 1 and the fixed frame 101, so that the container cylinder 202 can penetrate into the water. After reaching the appropriate depth, the winding roller 105 stops rotating.
