DETAILED DESCRIPTION

[0029] The following will be combined with the drawings in 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 in 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.

[0030] See also Figure 1-7 The utility model provides a technical solution: a water body sampler for river management based on automatic sampling of water flow, comprising a base 1, the base 1 is fixedly installed on an underwater pile foundation through a flange, and a sliding rod 2 is fixedly provided on the upper surface of the base 1, and a buoy 3 is slidably installed on the outer surface of the sliding rod 2, a rotating impeller 4 is provided inside the buoy 3, and the lower end of the impeller 4 passes through the lower surface of the buoy 3, a micro-generator 5 is fixedly installed inside the buoy 3, and the input shaft of the micro-generator 5 is fixedly connected to the rotating shaft of the impeller 4, and a battery 6 is provided inside the buoy 3 above the micro-generator 5, and a sampling mechanism is provided inside the buoy 3, and the sampling mechanism is automatically sampled by controlling the flow rate of water.

[0031] The sampling mechanism includes: a driving gear 7, which is fixedly arranged at one end of the rotating shaft of the impeller 4, a rotating reduction gear 8 is installed on the inner top surface of the buoyancy box 3, and the lower end of the rotating shaft of the reduction gear 8 is fixedly connected with a transmission gear 9, a rotating contact gear 10 and a trigger gear 11 are installed on the inner top surface of the buoyancy box 3, a trigger rod 12 is fixedly arranged on the lower surface of the trigger gear 11, a mounting plate 13 is fixedly arranged on the inner side surface of the buoyancy box 3, and a press switch 14 is fixedly arranged on the upper surface of the mounting plate 13, and a trigger lever 12 is fixedly arranged on the lower surface of the trigger gear 11, and a mounting plate 13 is fixedly arranged on the inner side surface of the buoyancy box 3. An electric push rod 15 is fixedly mounted on the lower surface of the mounting plate 13. The driving gear 7 and the transmission gear 9 are both bevel gear designs, and the driving gear 7 and the transmission gear 9 are meshed and connected. The driving gear 7 and the reduction gear 8 are both toothless designs with a tooth block on the surface, and the reduction gear 8 is meshed and connected with the contact gear 10. The trigger gear 11 is an internal gear design, and the trigger gear 11 is meshed and connected with the contact gear 10. The axial section of the trigger rod 12 is a right-angle trapezoid, and the inclined surface of the trigger rod 12 is arranged toward the press switch 14. When sampling, first, the base 1 is fixedly installed on the pile foundation pre-driven into the river through the flange. At this time, as the water level rises and falls, the buoy 3 can slide downward relative to the base 1 through the sliding rod 2. During the flow of water, the water flow impacts the impeller 4, causing the impeller 4 to rotate and drive the input shaft of the micro generator 5 to rotate. The micro generator 5 generates electricity and transmits electricity to the battery 6 for storage. At the same time, the impeller 4 drives the driving gear 7 to rotate and drives the transmission gear 9 to rotate periodically through meshing and toggling. At this time, the transmission gear 9 drives the reduction gear 8 to rotate. The reduction gear 8 toggles the contact gear 10 through the tooth block on the surface, causing the contact gear 10 to rotate periodically. The contact gear 10 drives the trigger gear 11 to rotate through meshing with the trigger gear 11. When the trigger gear 11 drives the trigger rod 12 to rotate and squeezes the push switch 14 at the corresponding position on the mounting plate 13 through the inclined surface of the trigger rod 12, the push switch 14 is triggered to send an electrical signal to the electric push rod 15, and the electric push rod 15 starts to drive the output end to move downward.

[0032] The sampling mechanism also includes: a liquid storage box 16, which is mounted on the lower surface of the floating tank 3 by means of a convex positioning snap-fit, a liquid storage cavity 17 is provided inside the side surface of the liquid storage box 16, and the liquid storage cavity 17 penetrates through the outer surface of the liquid storage box 16, and a filter screen 18 is fixedly provided at one end thereof, the upper surface of the liquid storage box 16 is penetrated by a closing plate 19, and a rotating locking plate 21 is installed on the upper surface of the liquid storage box 16 on one side of the closing plate 19, and a limit plate 22 is fixedly provided on the lower surface of the locking plate 21, and a limit plate 22 is fixedly provided on the lower end of the rotating shaft of the transmission gear 9 by means of a bolt to fix a limit plate Rod 20, the liquid storage box 16 is annularly designed, and the lower end of the liquid storage box 16 extends out of the lower surface of the float tank 3, the liquid storage cavity 17 is evenly distributed inside the side surface of the liquid storage box 16, the lower end of the closing plate 19 passes through the liquid storage cavity 17, and the closing plate 19 and the liquid storage box 16 are connected by sliding friction, and a spring is connected between the closing plate 19 and the upper surface of the liquid storage box 16, one end of the limit rod 20 is a new L design, and the outer surface of one end of the limit rod 20 L-shaped design is in contact with the outer surface of the liquid storage box 16, and the locking plate 21 is an arc-shaped plate with a cross section at one end. The outer surface of the cross section of the locking plate 21 fits with the side surface of the closing plate 19, and a spring is connected between the limit plate 22 and the upper surface of the liquid storage box 16. When one end of the electric push rod 15 moves downward to squeeze the closing plate 19 below, the closing plate 19 slides down and blocks the end of the liquid storage chamber 17 that passes through the side surface of the liquid storage box 16 through the lower end, so that the water inside the liquid storage chamber 17 will not continue to mix with the water in the river, ensuring the isolation of the pollution source in the sample taken at that time. When the closing plate 19 slides down to its place, the locking plate 21 is in the position between the limit plate 22 and the liquid storage chamber. The box 16 is pulled by the spring between the boxes and rotates to the upper end of the closing plate 19, so that the closing plate 19 cannot slide up to ensure the sealing of the liquid storage chamber 17. During the rotation of the transmission gear 9, the transmission gear 9 drives the limit rod 20 installed at the lower end to rotate, and the limit rod 20 scrapes the surface of the filter screen 18 so that the filter screen 18 will not be blocked. After the sampling is completed, the limit rod 20 is removed so that the liquid storage box 16 can be disengaged from the engagement with the float 3 as a whole, and then the water sample in the liquid storage chamber 17 is taken out by pouring it out.
