DETAILED DESCRIPTION

[0027] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0028] Example 1

[0029] The preferred embodiment of the water quality sample collection device for hydrological survey provided by the utility model is as follows Figures 1 to 5 As shown: a water quality sample collection device for hydrological survey, including a water inlet 1, a filtering mechanism 2, a threaded rod 21, a slider 22, a swing rod 23, a lifting column 24, a fixed column 25 and a filter plate 26, wherein the filtering mechanism 2 is arranged inside the water inlet 1, and the filtering mechanism 2 includes a threaded rod 21, a slider 22 is threadedly connected to the surface of the threaded rod 21, a swing rod 23 is rotatably connected to the side of the slider 22, a lifting column 24 is rotatably connected to the side of the swing rod 23, a fixed column 25 is fixedly connected to the surface of the lifting column 24, and a filter plate 26 is attached to the inner wall of the water inlet 1.

[0030] In this embodiment, the water inlet 1 is arranged in a rectangular shape, and a groove of the same size as the filter plate 26 is opened on the back of the water inlet 1. Because a groove of the same size as the filter plate 26 is opened on the back of the water inlet 1, the filter plate 26 can be conveniently embedded into the water inlet 1 through the groove on the back of the water inlet 1.

[0031] In this embodiment, the swing rod 23 is arranged at an angle, and the swing rod 23 forms a swing structure through the slider 22. Since the slider 22 is engaged with the threaded rod 21, when the threaded rod 21 rotates, it will drive the slider 22 to slide forward in the slide groove. At this time, the swing rod 23 rotationally connected to the slider 22 will swing downward accordingly.

[0032] In this embodiment, the connection position between the swing rod 23 and the lifting column 24 is located at their respective end points. The lifting column 24 drives the fixed column 25 through the swing rod 23 to form a lifting structure. Since the lifting column 24 is rotationally connected to the swing rod 23, when the swing rod 23 swings, it will drive the lifting column 24 to slide downward in the slide groove, and at this time, the fixed column 25 fixedly connected to the lifting column 24 will slide downward accordingly.

[0033] In this embodiment, a fixing groove that is the same size as the fixing column 25 is formed on the top of the filter plate 26 and the inner wall of the water inlet 1. The fixing column 25, the filter plate 26 and the water inlet 1 together constitute a fixed structure. Because a fixing groove that is the same size as the fixing column 25 is formed on the top of the filter plate 26 and the inner wall of the water inlet 1, when the fixing column 25 slides to pass through the fixing groove of the filter plate 26 and is embedded in the fixing groove of the water inlet 1, the filter plate 26 can be fixed inside the water inlet 1, thereby achieving the purpose of filtering impurities and preventing some large impurities from mixing into the sample and affecting the detection results.

[0034] Example 2

[0035] On the basis of Example 1, a preferred embodiment of the water sample collection and medicine filling device for preventing medicine residue provided by the utility model is as follows: Figures 1 to 5As shown: the bottom of the water inlet 1 is fixedly connected with a water tank 3, the surface of the water tank 3 is fitted with a first placement groove 4, the surface of the first placement groove 4 is fitted with a second placement groove 5, the tops of the first placement groove 4 and the second placement groove 5 are both provided with a fixing mechanism 6, the fixing mechanism 6 includes a rotating column 61, the surface of the rotating column 61 is threadedly connected with a fastening nut 62, the surface of the rotating column 61 is located below the fastening nut 62 and fixedly connected with a disc 63, the bottom of the disc 63 is fixedly connected with a supporting column 64, the top of the disc 63 is rotatably connected with a rotating rod 65, the bottom of the rotating rod 65 is rotatably connected with a fixing plate 66, the side of the first placement groove 4 is fixedly connected with a spring 7, and the surface of the second placement groove 5 is fixedly connected with a handle 8.

[0036] In this embodiment, the rotating column 61 is located at the center of the disk 63, and the disk 63 forms a rotating structure through the rotating column 61. Since the disk 63 is fixedly connected to the rotating column 61, when the rotating column 61 rotates, it will drive the disk 63 to rotate clockwise.

[0037] In this embodiment, two groups of support columns 64 are symmetrically arranged about the center of the disk 63, and the tops of the first placement groove 4 and the second placement groove 5 are both provided with annular sliding grooves. Since the two groups of support columns 64 are fixedly connected to the disk 63, when the disk 63 rotates, the two groups of support columns 64 will be driven to slide in the annular sliding groove at the top of the first placement groove 4, and play a certain supporting and limiting role on the disk 63.

[0038] In this embodiment, the rotating rod 65 is set to deviate from the center of the disk 63, and the rotating rod 65 is set at an angle. Because the rotating rod 65 is rotationally connected to the disk 63, when the disk 63 rotates, it will drive the rotating rod 65 to rotate together, and apply a rightward thrust to the fixed plate 66, so that the fixed plate 66 rotationally connected to the rotating rod 65 slides to the right in the slide groove of the inner wall of the first placement groove 4. When the fixed plate 66 slides to be completely in contact with the water tank 3, tighten the fastening nut 62 to fix the fixed plate 66 in the current position, so that the water tank 3 can be fixed inside the first placement groove 4 to prevent the water tank 3 from falling during the sample collection process.

[0039] In this embodiment, the two ends of the spring 7 are fixedly connected to the first placement groove 4 and the second placement groove 5 respectively. Because the first placement groove 4 and the second placement groove 5 are slidably connected, and the two ends of the spring 7 are fixedly connected to the first placement groove 4 and the second placement groove 5 respectively, the staff can adjust the length of the first placement groove 4 and the second placement groove 5 according to the length of the sink 3.

[0040] The working principle and use process of the utility model are as follows: first, the filter plate 26 is inserted into the water inlet 1 through the groove on the back side of the water inlet 1, and then the threaded rod 21 is manually rotated clockwise. Since the slider 22 is meshed with the threaded rod 21, when the threaded rod 21 rotates, the slider 22 is driven to slide forward in the slide groove. At this time, the swing rod 23 rotatably connected to the slider 22 will swing downward accordingly. Since the lifting column 24 is rotatably connected to the swing rod 23, when the swing rod 23 swings, the lifting column 24 is driven to slide downward in the slide groove. At this time, the fixing column 25 fixedly connected to the lifting column 24 will slide downward accordingly. Because the top of the filter plate 26 and the inner wall of the water inlet 1 are both provided with a fixing groove of the same size as the fixing column 25, when the fixing column 25 slides to pass through the fixing groove of the filter plate 26 and is embedded in the fixing groove of the water inlet 1, the filter plate 26 can be fixed inside the water inlet 1, so as to achieve the purpose of filtering impurities and prevent some large impurities from mixing into the sample and affecting the detection result.

[0041] In order to prevent the water tank 3 from falling, the rotating column 61 can be manually controlled to rotate clockwise. Since the disc 63 is fixedly connected to the rotating column 61, when the rotating column 61 rotates, the disc 63 will be driven to rotate clockwise together. Since the two groups of supporting columns 64 are fixedly connected to the disc 63, when the disc 63 rotates, the two groups of supporting columns 64 will be driven to slide in the annular groove at the top of the first placement groove 4, and play a certain supporting and limiting role for the disc 63. Since the rotating rod 65 is rotationally connected to the disc 63, when the disc 63 rotates, the rotating rod 65 will be driven to rotate together, and a rightward push will be applied to the fixed plate 66. The force causes the fixing plate 66 rotatably connected to the rotating rod 65 to slide to the right in the slide groove of the inner wall of the first placement groove 4. When the fixing plate 66 slides to be completely in contact with the water tank 3, the fastening nut 62 is tightened to fix the fixing plate 66 in the current position, so that the water tank 3 can be fixed inside the first placement groove 4 to prevent the water tank 3 from falling during the sample collection process. Because the first placement groove 4 and the second placement groove 5 are slidably connected, and the two ends of the spring 7 are fixedly connected to the first placement groove 4 and the second placement groove 5 respectively, the staff can adjust the length of the first placement groove 4 and the second placement groove 5 according to the length of the water tank 3.

[0042] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
