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.

A measuring mechanism is arranged inside the shell 1, and the measuring mechanism includes a float 3 with a hollow interior. The overall density of the float 3 is smaller than the density of water and can float on the water surface. It is a prior art. The top of the float 3 is fixedly connected with a scale rod 4 arranged in a vertical state, and the scale rod 4 is slidably installed on the inner wall of the limit ring 2. The surface of the scale rod 4 is provided with scale lines 5 for the staff to read the readings conveniently, so that the staff can understand the water level of the river channel conveniently. The left and right sides of the shell 1 are provided with mounting mechanisms.

[0033] Reference Figure 2 - Figure 4 The installation mechanism includes a connecting frame 6 and a support column 9 arranged in a vertical state. The support column 9 plays a supporting role to improve the stability of the shell 1 when working. The number of connecting frames 6 is set to multiple, and a positioning block 8 is fixedly connected to the side away from each other of the multiple connecting frames 6. A groove 7 matching the connecting frame 6 is opened on the inner wall of the shell 1, and a positioning groove 10 matching the positioning block 8 is opened on the inner wall of the support column 9. The support column 9 is fixedly connected to the connecting frame 6 by a fastening bolt 11. A positioning hole 12 matching the fastening bolt 11 is opened on the surface of the support column 9. A plurality of support plates 13 are fixedly connected to the surface of the support column 9 to increase the contact area with the mud at the bottom of the river channel and improve the installation stability of the support column 9. A connecting pipe 14 arranged in a horizontal state is fixedly connected to the front of the shell 1, and a filtering mechanism is arranged inside the connecting pipe 14.

[0034] Reference Figure 2 - Figure 4 The shape of the connecting frame 6 is set to be L-shaped, the positioning block 8 is set on the longer side of the L-shape of the connecting frame 6, and the short side of the connecting frame 6 is inserted into the inner wall of the groove 7. The two groups of shells 1 are merged into a complete cavity through the connecting frame 6 to prevent external waves from causing the water level inside the two groups of shells 1 to fluctuate up and down, resulting in the up and down displacement of the scale rod 4, thereby affecting the accuracy of reading the scale line 5. The number of positioning holes 12 is set to be multiple, and the multiple positioning holes 12 are arranged on the surface of the support column 9 in a straight line with equal intervals. The fastening bolts 11 pass through the inside of the positioning holes 12. By setting the fastening bolts 11 with multiple positioning holes 12, the distance between the shell 1 and the bottom of the support column 9 can be changed, and then the distance from the bottom of the river channel can be adjusted, which can adapt to the complex installation environment of rivers with various water levels.

[0035] Reference Figure 1 , Figure 5 , Figure 6The filtering mechanism includes a filter box 15, which is fixedly mounted on the outer wall of the connecting pipe 14. The filtering mechanism also includes a pull ring 16 for facilitating the staff to pull the limit rod 17, which is convenient and labor-saving. The bottom of the pull ring 16 is fixedly connected with a limit rod 17 arranged in a vertical state. The limit rod 17 is slidably mounted on the inner wall of the filter box 15. The sliding direction of the limit rod 17 is up and down sliding. The bottom of the limit rod 17 is fixedly connected with a wedge block 18. The top of the wedge block 18 is elastically connected to the inner wall of the filter box 15 through a spring 19. The spring 19 is provided to apply an elastic force downward to the wedge block 18.

[0036] Reference Figure 5 , Figure 6 The filtering mechanism also includes a handle 20 and a mounting plate 21, which are fixedly connected to the mounting plate 21, and the mounting plate 21 is plugged into the inner wall of the filter box 15. A filter plate 23 for filtering debris in the river water is fixedly connected to the inner wall of the mounting plate 21 to prevent debris in the river water from entering the interior of the shell 1 and being adsorbed on the surface of the scale rod 4, resulting in poor up and down displacement of the scale rod 4, thereby affecting the accuracy of water level measurement. A limiting groove 22 matching the wedge block 18 is provided on the top of the mounting plate 21, and the bottom of the wedge block 18 contacts the inner wall of the limiting groove 22. The bottom of the wedge block 18 is provided with an inclined surface, and the inner wall of the limiting groove 22 is provided with an inclined surface. The interior of the shell 1 is connected to the outside of the shell 1 through the connecting pipe 14, so the water level of the river water is the same as the water level inside the shell 1, so that the scale rod 4 can accurately measure the height of the water level, and the surface of the filter plate 23 is provided with a sieve hole.

[0037] Working principle: When in use, insert the support column 9 into the bottom of the river channel, and insert the support plate 13 into the soil at the bottom of the river channel to increase the contact area between the support column 9 and the soil at the bottom of the river channel, increase the stability of the installation, and then place the scale rod 4 between the two sets of limit rings 2, and then insert the L-shaped short side of the connecting frame 6 into the inner wall of the groove 7, and then merge the two sets of shells 1 so that the two sets of shells 1 become a whole, and then move the shell 1 downward so that the positioning block 8 on the surface of the connecting frame 6 is inserted into the positioning groove 10 on the inner wall of the support column 9, and then fix the connecting frame 6 and the support column 9 by fastening bolts 11 to complete the installation of the water level measuring device. At the same time, by installing the fastening bolts 11 in the positioning holes 12 at different positions, the distance between the shell 1 and the bottom of the river channel can be adjusted, which can adapt to the installation and detection work of rivers with different water levels.

[0038] By pulling the pull ring 16 upward, the limiting rod 17 is driven to move upward, and then the wedge block 18 is driven to move upward to overcome the elastic force of the spring 19, so that the wedge block 18 is disengaged from the inside of the limiting groove 22, and the mounting plate 21 can be moved by pulling the handle 20, so that the filter plate 23 can be easily and quickly removed from the inside of the filter box 15 for replacement, thereby avoiding the clogging of the filter plate 23 and affecting the water level detection work.
