However, when the water surface is frozen, it is impossible to judge the thickness of the ice surface, and there is a certain risk for the inspector to stand on the ice surface to take samples. Therefore, the present application proposes a water quality sampling device. Summary of the invention

[0023] The technical solution of the present utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present utility model, rather than all of the embodiments.

[0024] Example

[0025] like Figure 1 As shown, a water quality sampling device proposed by the utility model includes a base plate 1, two support seats 4 are installed at the bottom of the base plate 1, a support plate 5 is fixed between the tops of the two support seats 4, a cylinder 6 is installed on the support plate 5, a piston rod of the cylinder 6 is fixed with a remote control car located below the support plate 5, a lifting mechanism is arranged on the support plate 5, the lifting mechanism is connected with an ice breaking sampling mechanism, and a fixing component 2 located on both sides of the support seat 4 is fixedly installed on the top of the base plate 1 for fixing the base plate 1 when breaking ice.

[0026] like Figure 1 As shown, notches of the same size are provided on both sides of the bottom plate 1, and the notches are located directly below the four wheels of the remote control car. The function of the notches is to make the wheels of the remote control car contact the ground when the cylinder 6 is running, so as to avoid scratches with the bottom plate 1.

[0027] like Figure 1-3As shown, the lifting mechanism includes a fixed box 8 fixedly installed on the top of the support plate 5, and a reinforcing rib 7 is fixedly installed on one side of the fixed box 8. The function of the reinforcing rib 7 is to improve the bearing capacity of the fixed box 8. The other end of the reinforcing rib 7 is fixedly connected to the top of the support plate 5. A screw rod 21 is rotatably installed inside the fixed box 8, and also includes two fixedly installed guide rods 20, and the guide rods 20 are located on both sides of the screw rod 21. A motor 9 is fixedly installed on the top of the fixed box 8, and the output shaft of the motor 9 is rotatably connected to the screw rod 21. A slider 10 is rotatably installed on the screw rod 21, and a sliding hole is opened on the slider 10. The guide rod 20 is slidably connected to the wall of the sliding hole, which can be used in conjunction with the ice-breaking sampling mechanism to achieve the effect of breaking ice layers of various thicknesses.

[0028] like Figure 1 As shown, the ice-breaking sampling mechanism includes a fixed block 11 fixedly installed on one side of the slider 10, a reinforcing rib 13 is fixedly installed at the bottom of the fixed block 11, and the reinforcing rib 13 can improve the bearing capacity of the fixed block 11. The other end of the reinforcing rib 13 is fixedly connected to the side of the slider 10, and a motor 12 is fixedly installed at the front end of the top of the fixed block 11. An opening is opened on the fixed block 11, and a rotating rod 14 is slidably connected to the hole wall of the opening. The rotating rod 14 is rotatably connected to the output shaft of the motor 12, and an L-shaped limit block 15 is fixedly installed on the outer wall of the rotating rod 14. A rotating cutter head 19 is threadedly connected to the bottom of the rotating rod 14. A tray 17 is fixedly installed on the column of the rotating cutter head 19, and a sampling container 16 is movably installed on the tray 17. The cutter head 19 and the rotating rod 14 are detachably threadedly connected. On the one hand, this is to facilitate the disassembly and replacement of the rotating cutter head 19 when it is worn out and cannot be used. On the other hand, after the water sample is collected, the sampling container 16 movably installed on the column of the rotating cutter head 19 is removed for water quality testing. The other end of the L-shaped limit block 15 is against the top surface of the sampling container 16. Its function is to limit the position of the sampling container 16 when the rotating cutter head is working, and it will not shake up and down on the column of the rotating cutter head. The material of the L-shaped limit block 15 is rubber, which will not cause damage to the sampling container 16. The diameter of the sampling container 16 does not exceed the outer diameter of the blade of the rotating cutter head 19, preventing the sampling container 16 from entering the opening broken by the rotating cutter head 19 for sampling.

[0029] like Figure 4 As shown, a water inlet is provided on the top of the sampling container 16, and a filter screen 18 is fixedly installed on the inner wall of the water inlet. The water inlet is for the convenience of sampling the water quality of the container, and the filter screen 18 prevents the entry of debris during the water intake process, which may affect the water quality detection.

[0030] like Figure 1-5As shown, the fixing assembly 2 includes an L-shaped fixing seat 202 fixedly installed on both sides of the top of the base plate 1, a telescopic motor 201 is fixedly installed on the top of the L-shaped fixing seat 202, and also includes a protection box 204 fixedly installed on the top of the base plate 1 and located on one side of the L-shaped fixing seat 202. The top of the protection box 204 and the base plate 1 are provided with the same threaded holes, and an ice screw 203 is threadedly connected to the wall of the threaded hole, and the top of the ice screw 203 is rotatably connected to the output shaft of the telescopic motor 201. After the sampling device reaches the specified position, the driving mechanism is retracted, the base plate 1 contacts the ice surface, and the telescopic motor 201 is started, driving the ice screw 203 to rotate downward and rotate into the ice layer, thereby achieving the purpose of fixing the sampling device on the ice surface and reducing the shaking of the sampling device during ice breaking.

[0031] Working principle: through the operation of cylinder 6, the remote control car is lowered to contact the ice surface, and the sampling device is moved by remote control to realize the free movement of the sampling device on the ice surface. After reaching the specified position, cylinder 6 stops working and lifts the remote control car back to the top of the bottom plate 1, then the fixing component 2 is started, and the telescopic motor 201 works to drive the ice screw 203 to rotate and drill into the ice layer, so as to achieve the purpose of fixing the sampling device on the ice surface, and reduce the shaking of the sampling device during the operation of the lifting mechanism and the ice breaking sampling mechanism, which affects the ice breaking work. Further, the lifting mechanism motor 19 is started, and the slider 10 moves downward under the action of the screw rod 21 and the guide rod 20. At the same time, the motor 2 12 is started to drive the rotating rod 14 and the rotating rod 14 threadedly connected. The rotary cutter head 19 rotates and opens the ice surface with the cooperation of the lifting mechanism. The L-shaped limit block 15 limits the sampling container 16 to prevent the sampling container 16 from shaking up and down during the ice breaking operation. The rotary cutter head 19 stops after breaking the ice surface until the sampling water is visible. The lifting mechanism lowers the sampling container 16 underwater and samples the water through the water inlet, which achieves the goal of sampling the water without having to stand on the ice layer to destroy the ice layer. This reduces the risk of water quality inspectors and reduces their workload. Thereafter, the lifting mechanism is raised, the cylinder 6 is started, the remote control car is lowered, and the remote control car is moved to the shore with the sampling device remotely controlled, the rotary cutter head 19 is rotated and removed, the sampling container 16 is taken away, and the water in the container is poured out for testing.

[0032] The above-mentioned specific water quality sampling devices are only several optional water quality sampling devices of the utility model. Based on the technical scheme of the utility model and the relevant inspiration of the above-mentioned water quality sampling devices, technical personnel in this field can make various alternative improvements and combinations to the above-mentioned specific water quality sampling devices.
