DETAILED DESCRIPTION

[0025] In order to further understand the content, features and effects of the present invention, the following embodiments are given as examples and described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 3 As shown, the embodiment of the present invention provides a water level observation device that is convenient for sampling, comprising:

[0027] A support base 1 is provided with a through opening 2 at the upper end of the support base 1, and a first side plate 4 and a second side plate 5 are fixedly connected to both sides of the upper end of the support base 1. A mounting plate 6 is provided on the right side above the support base 1, and fixing blocks 7 are provided on both sides of the mounting plate 6. A locking hole 8 is provided at the upper end of the fixing block 7, and a water intake tank 9 is fixedly connected to both sides of the fixing block 7. The lower end of the mounting plate 6 is fixedly connected to a water level gauge 3;

[0028] The water inlet structure 11, the assembly structure 12 and the retractable structure 13, the water inlet structure 11 is located in the water intake tank 9, the water inlet structure 11 is used for sampling water inlet and outlet of the water intake tank 9, the assembly structure 12 is located on the mounting plate 6, the assembly structure 12 is used for disassembly and assembly of the fixed block 7, the retractable structure 13 is located on the first side plate 4, the retractable structure 13 is used to drive the extension and retraction of the water intake tank 9 and the water level meter 3.

[0029] Furthermore, the water inlet structure 11 includes an annular water inlet hole 111, and an annular counterweight plate 112 is arranged inside the annular water inlet hole 111. The upper end of the annular counterweight plate 112 is fixedly connected to a top rod 113, and the upper end of the top rod 113 passes through the upper end of the water intake tank 9 and is fixedly connected to a buoyancy ball 114. When it is necessary to sample water sources in underground gaps and foundation pit observation wells, first insert the fixed block 7 on the water intake tank 9 into the positioning groove 121, and then insert the fixing wire 123 into the locking hole 8, and fix the fixing wire 123 to the wire hole 122, and then fix the water intake tank 9.

[0030] The provision of the annular counterweight plate 112 provides a good sealing effect on the annular water inlet 111 during use, thereby preventing the annular water inlet 111 from leaking after sampling is completed.

[0031] Furthermore, the assembly structure 12 includes a positioning groove 121, the interior of the positioning groove 121 is plugged into the surface of the fixed block 7, a wire hole 122 is opened at the lower end of the interior of the positioning groove 121, and fixing wires 123 are provided on both sides of the upper end of the mounting plate 6. The lower end of the fixing wire 123 passes through the locking hole 8 and is fixedly connected to the wire hole 122. Then the driving motor 131 drives the reel 132 to start rotating through the bearing seat, and the reel 132 releases the mounting plate 6 through the soft steel wire rope 133 and the steel wire rope connector 134. The mounting plate 6 simultaneously releases the water level meter 3 and the water intake tank 9 downward, so that the water level meter 3 and the water intake tank 9 enter the water source at the same time, so that the water level meter 3 collects water source information.

[0032] The mutual cooperation of the positioning groove 121, the fixing wire 123 and the wire hole 122 facilitates the disassembly and assembly of the fixing block 7 during use, thereby solving the problem that the fixing block 7 is inconvenient to disassemble and assemble during use.

[0033] Furthermore, the retractable structure 13 includes a drive motor 131, the output end of the drive motor 131 passes through the right side of the first side plate 4 and is fixedly connected to a drum 132, a soft steel wire rope 133 is wound around the surface of the drum 132, and one end of the soft steel wire rope 133 is fixedly connected to a wire rope connector 134, and the lower end of the wire rope connector 134 is fixedly connected to the upper end of the mounting plate 6. At the same time, when the water intake tank 9 enters the water source, due to the action of the buoyancy ball 114, the buoyancy ball 114 will float upward, and the buoyancy ball 114 can drive the top rod 113 to move upward, and the top rod 113 drives the annular counterweight plate 112 to move out of the annular water inlet hole 111, and the water source can enter the water intake tank 9 through the annular water inlet hole 111. In the process of water intake of the water intake tank 9, the air inside it will be discharged through the exhaust hole 14 to prevent the water intake of the water intake tank 9 from being unable to enter due to the presence of air.

[0034] The arrangement of the wire rope connector 134 can stabilize and fix the soft wire rope 133 and the mounting plate 6 during use, thereby preventing the soft wire rope 133 and the mounting plate 6 from falling off during use.

[0035] Furthermore, an exhaust hole 14 is opened on one side of the upper end of the water tank 9, and the exhaust hole 14 is used to discharge the air in the water tank 9. A sealing plug is provided at the upper end of the exhaust hole 14. After the sampling is completed, the water level meter 3 and the water tank 9 are reset in the above manner. During the reset process, the buoyancy of the buoyancy ball 114 disappears when it is exposed to the water surface.

[0036] The provision of the sealing plug provides a good dustproof effect on the exhaust hole 14 during use, preventing external dust from entering the water tank 9 through the exhaust hole 14 and affecting the detection of the sampled water in the water tank 9.

[0037] Furthermore, a displacement sensor 10 is fixedly connected to the left side of the second side plate 5. The displacement sensor 10 is used to measure the length of the soft steel wire rope 133 released, and the annular counterweight plate 112 will reset downward and insert the annular counterweight plate 112 into the annular water inlet hole 111 to prevent water in the water tank 9 from leaking.

[0038] By setting the displacement sensor 10, the length of the soft steel wire rope 133 can be monitored during the release process, thereby assisting the water level meter 3 in performing auxiliary detection of the height difference at the water source, thereby increasing the detection accuracy.

[0039] Furthermore, a sealing ring is provided at the connection between the surface of the annular counterweight plate 112 and the inside of the annular water inlet hole 111, and the sealing ring is made of nitrile rubber. When the water in the water intake tank 9 needs to be discharged, the operator only needs to pull the buoyancy ball 114 upwards, and the top rod 113 will drive the annular counterweight plate 112 to separate from the annular water inlet hole 111, and the water intake tank 9 will discharge the water through the annular water inlet hole 111.

[0040] The provision of the sealing ring increases the sealing performance of the annular counterweight plate 112 and the annular water inlet hole 111 during use, thereby preventing the annular counterweight plate 112 and the annular water inlet hole 111 from having poor sealing performance during use.

[0041] Furthermore, a bearing seat is sleeved on the right side of the reel 132 , and the right side of the bearing seat is fixedly connected to the left side of the second side plate 5 .

[0042] The arrangement of the bearing seat ensures that the reel 132 rotates smoothly during use, thereby preventing the reel 132 from shaking during use.

[0043] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
