DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] Reference Figure 1-Figure 5 , a water environment detection device convenient for sampling at different depths, comprising:

[0026] Shell 1.

[0027] The sampling mechanism includes a water pump 2, a rotating frame 3, a water suction pipe 4 and a water outlet pipe 12. The water pump 2 is installed at the bottom of the shell 1. The top of the shell 1 is rotatably connected to the rotating frame 3, and the water suction pipe 4 is wound around the rotating frame 3. A through hole 6 is opened on one side of the top of the shell 1, and an axial channel 31 is coaxially opened in the rotating frame 3. One end of the water suction pipe 4 is connected to the axial channel 31, and the other end passes through the through hole 6. The input end of the water pump 2 and the axial channel 31 are rotatably matched and connected to each other away from the end of the water suction pipe 4, and the output end is connected to the water outlet pipe 12.

[0028] The input end of the water pump 2 passes through the housing 1 and is coaxially rotatably connected to the axial channel 31 through an adapter, so that when the rotating frame 3 rotates, the input end of the water pump 2 is not driven to rotate, and the connection effect with the water pump 2 is maintained.

[0029] The detection component includes a water sample detector 15, which is installed on the outside of the shell 1. The end of the water outlet pipe 12 away from the water pump 2 is connected to the input end of the water sample detector 15. A water outlet valve 13 is installed on the water outlet pipe 12, and the water outlet valve 13 is used to conveniently control the on and off of the water flow.

[0030] The bottom of the water sample detector 15 is connected to a drain pipe, and a valve is installed on the drain pipe for discharging water after the detection.

[0031] One end of the water suction pipe 4 extending through the hole 6 is fixedly connected to a counterweight 5, and a water hole connected to the water suction pipe 4 is penetrated through the counterweight 5 to improve the verticality of the water suction pipe 4 after being released, and to prevent the water suction pipe 4 from bending excessively and affecting the detection effect of water samples at different depths.

[0032] A placement platform 14 is fixedly connected to the outside of the shell 1, and the placement platform 14 is located on one side of the through hole 6. The counterweight block 5 is initially placed on the placement platform 14 to facilitate the placement of the counterweight block 5, thereby preventing the counterweight block 5 from continuously causing a pulling effect on the water pumping pipe 4 and improving the service life of the water pumping pipe 4.

[0033] One end of the rotating frame 3 passes through the shell 1 and is coaxially fixedly connected with a rotating handle 7. The rotating handle 7 is L-shaped and is covered with a protective pad at the end away from the shell 1. The protective pad is made of rubber, which makes it convenient to control the rotation of the rotating frame 3 by rotating the handle 7 to reel in and release the water pump 4.

[0034] A limit assembly is connected to the rotating handle 7, and the limit assembly includes a limit column 8 and a limit spring 10. The limit column 8 is slidably connected to the rotating handle 7, and the limit spring 10 is fixedly connected between the limit column 8 and the rotating handle 7. A limit hole 11 is opened on the outside of the shell 1, and one end of the limit column 8 is snap-fitted with the limit hole 11.

[0035] A wedge-shaped groove 9 is formed at one end of the limiting column 8 that cooperates with the limiting hole 11 , wherein the wedge-shaped inclined surface of the wedge-shaped groove 9 is located on the back side of the rotation direction of the rotating frame 3 to release the water pumping pipe 4 .

[0036] The operating principle of the utility model is now described as follows:

[0037] When sampling water bodies at different depths, first remove the counterweight 5 from the placement table 14, and under the action of the gravity of the counterweight 5, the water pumping pipe 4 is pulled vertically downward, and then the limit column 8 is pulled out, and the rotating handle 7 is controlled to rotate in the opposite direction, so that the rotating frame 3 can be rotated in the opposite direction to loosen the water pumping pipe 4, so that the counterweight 5 drives the water pumping pipe 4 into the water body;

[0038] When the rotating frame 3 rotates, the water pump 4 is connected to the input end of the water pump 2 through the axial channel 31 and the rotatable adapter, so as to prevent the input end of the water pump 2 from rotating when the rotating frame 3 rotates;

[0039] By controlling the length of the water pumping pipe 4, the limit column 8 is released at the corresponding position, and the locking of the rotating frame 3 is completed by the clamping cooperation between the limit column 8 and the limit hole 11, so that the input end of the water pumping pipe 4 can be located at different depths of the water body, and finally the water pump 2 is controlled to work, and the input end of the water pump 2 performs a water pumping sampling operation at different depths of the water body through the water pumping pipe 4;

[0040] The output end of the water pump 2 outputs the sampled water to the water sample detector 15 through the water outlet pipe 12, so as to quickly form a detection effect on the water body;

[0041] When retracting the water pumping pipe 4, the handle 7 is controlled to rotate forward. Under the action of the wedge-shaped groove 9 on the limiting column 8, the limiting column 8 directly passes through the limiting hole 11, which facilitates the rapid reeling of the water pumping pipe 4. Finally, the counterweight block 5 is placed on the placement table 14 to complete the entire operation.

[0042] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
