[0021] In order to be able to press down and fix the sampler 8 from the upper side so that the sampler 8 can be stably placed on the mounting mechanism 7, the mounting mechanism 7 includes an upper connecting plate 71, the top surface of the upper connecting plate 71 is fixedly connected to the lower end of the suspension rope 6, and a lower connecting plate 72 is provided at the bottom of the upper connecting plate 71. Connecting rods 73 are fixedly connected at the four corners of the bottom surface of the upper connecting plate 71, and the bottom surfaces of the four connecting rods 73 are respectively fixedly connected to the four corners of the top surface of the lower connecting plate 72. The sampler 8 is placed on the lower connecting plate 72, and a fixing plate 74 is provided at the top of the sampler 8. The bottom surface of the fixing plate 74 fits the top surface of the sampler 8. Movable holes are provided at the four corners of the fixing plate 74. The upper ends of the four connecting rods 73 are respectively movably sleeved in adjacent movable holes. The upper ends of the surfaces of the four connecting rods 73 are provided with threads, and the upper end of the surface of each connecting rod 73 is threadedly sleeved with a nut 75, and the bottom surface of the nut 75 fits the top surface of the fixing plate 74.

[0022] In order to improve the stability of the sampler 8 placed on the mounting mechanism 7 and prevent the sampler 8 from moving left and right and front and back, lower fixing blocks 76 are provided on the left and right sides of the top surface of the lower connecting plate 72, upper fixing blocks 77 are provided on the left and right sides of the bottom surface of the fixing plate 74, lower slots 78 are provided on the left and right sides of the bottom surface of the sampler 8, and upper slots 79 are provided on the left and right sides of the top surface of the sampler 8. The two lower fixing blocks 76 are respectively inserted in adjacent lower slots 78, and the two upper fixing blocks 77 are respectively inserted in adjacent upper slots 79.

[0023] In order to enable the installation mechanism 7 to enter the protective frame 10 and then be removed therefrom, and at the same time, to prevent debris from entering the protective frame 10 from the top when the installation mechanism 7 enters the protective frame 10, the protective frame 10 has a bottom opening structure, and the installation mechanism 7 is movably sleeved inside the protective frame 10, and the side surface of the inner wall of the protective frame 10 is in contact with the side surface of the outer wall of the upper connecting plate 71 and the lower connecting plate 72.

[0024] In order to prevent the protective frame 10 from falling off directly from the mounting mechanism 7 when the mounting mechanism 7 is moved out of the protective frame 10, movable holes are opened on the left and right sides of the bottom of the protective frame 10, and a limiting rod 11 is movably sleeved in each movable hole. The lower and upper ends of the limiting rod 11 respectively penetrate the inner and outer sides of the protective frame 10, and the top surfaces of the two limiting rods 11 are respectively fixedly connected to the left and right sides of the bottom surface of the lower connecting plate 72, and the bottom surface of the limiting rod 11 is fixedly connected to the limiting block 12.

[0025] In order to conveniently control the operation of the electric slide rail 4 and the hoist 5 , a control box 13 is fixedly connected to the top surface of the base 1 , and the electric slide rail 4 and the hoist 5 are both electrically connected to the control box 13 .

[0026] Working principle: When the utility model is used, first start the operation of the winch 5 controlled by the control box 13, the winch 5 releases the lifting rope 6, and the sampler 8 is placed in the water. First, the protection frame 10 will contact the water. Since the density of the protection frame 10 is less than the density of water, the protection frame 10 will float on the water surface and will not enter the water temporarily, and the mounting mechanism 7 and the sampler 8 will descend and enter the protection frame 10. When the mounting mechanism 7 enters the bottom of the protection frame 10, the weight of the mounting mechanism 7 and the sampler 8 will press the protection frame 10 into the water. At this time, water will enter the protection frame 10 through the filter hole and enter the sampler 8 through the water inlet opening 9, so as to collect and sample the water. The filter hole filters large debris in the water to prevent large aquatic plants and large debris from clogging the water inlet opening 9 and causing sampling difficulties. After the sampling is completed, the winch 5 retracts the lifting rope 6, and the lifting rope 6 will install the mounting mechanism 7 and The sampler 8 is pulled out of the water, and the protection frame 10 will automatically drop, so that the mounting mechanism 7 and the sampler 8 are moved out of the protection frame 10, leaving only the connecting plate 72 at the top of the inner cavity of the protection frame 10. The limit block 12 limits the descending distance of the protection frame 10 to prevent the protection frame 10 from falling directly from the mounting mechanism 7. Then the control box 13 controls the electric slide 4 to move the winch 5 to the left and move the sampler 8 to the shore. When the sampler 8 needs to be removed from the mounting mechanism 7, it is raised by screwing the nut 75 to release the fixation of the fixing plate 74, and then the fixing plate 74 is pushed upward to move the upper fixing block 77 out of the upper slot 79 to release the fixation of the sampler 8. Then the sampler 8 is lifted up to move the lower fixing block 76 out of the lower slot 78, and the sampler 8 can be removed from the mounting mechanism 7, which is convenient for disassembly of the sampler 8, thereby facilitating the removal of the collected samples for testing.

[0027] The technical features of the above embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
