[0033] The present application provides a water depth measuring instrument with a float.

[0034] As Figures 1 to 4The water depth measuring instrument with a float includes a telescopic measuring rod 1, a counterweight mechanism 2 and a floating mechanism 3. One end of the telescopic measuring rod 1 is detachably connected to the counterweight mechanism 2. The counterweight mechanism 2 is used to abut the bottom of a water area with the movement of the end of the telescopic measuring rod 1, so that the telescopic measuring rod 1 abuts the bottom of the water area in the vertical direction. The floating mechanism 3 is sleeved on the telescopic measuring rod 1 and is arranged in the length direction of the telescopic measuring rod 1. When the end of the telescopic measuring rod 1 connected to the counterweight mechanism 2 is inserted into the water area, the floating mechanism 3 floats on the water surface, so that the floating mechanism 3 marks the depth data of the telescopic measuring rod 1 inserted into the water area.

[0035] The counterweight mechanism 2 serves as a counterweight to increase the contact area of the telescopic measuring rod 1 and the river bottom, so as to avoid the telescopic measuring rod 1 from being inserted into silt. The counterweight mechanism 2 is used to fix the position of the end of the telescopic measuring rod 1 inserted into the river bottom, so as to avoid the water flow from driving the telescopic measuring rod 1 and effectively prevent the telescopic measuring rod from tilting during measurement. Meanwhile, the floating mechanism 3 can facilitate the user to accurately determine the depth data of the telescopic measuring rod inserted into the river bottom.

[0036] Specifically, the telescopic measuring rod 1 is a staff gauge.

[0037] Specifically, the telescopic measuring rod 1 is detachably connected to the counterweight mechanism 2 and the floating mechanism 3. When not in use, the telescopic measuring rod 1, the counterweight mechanism 2 and the floating mechanism 3 are separated, so as to facilitate the overall carrying and transportation.

[0038] The counterweight mechanism 2 includes a counterweight box 21 and a first fixing member 4. The first fixing member 4 is arranged on one side of the counterweight box 21. The first fixing member 4 is used to fix one end of the telescopic measuring rod 1 to the outside of the counterweight box 21, so that the end of the telescopic measuring rod 1 adjacent to the counterweight box 21 is flush with the end of the counterweight box 21 close to the bottom of the water area.

[0039] A liquid storage space 22 is formed in the counterweight box 21. The counterweight box 21 is provided with a liquid injection port 23. The liquid injection port 23 is communicated with the liquid storage space 22. A detachable plug 24 is arranged at the liquid injection port 23. The liquid storage space 22 is used to store water. When in use, the counterweight box 21 and the telescopic measuring rod 1 are fixed by the first fixing member 4. Then, the plug 24 is removed. The counterweight box 21 is immersed in water until the liquid storage space 22 is filled with water. Then, the liquid injection port 23 is closed by the plug 24. The counterweight box 21 is weighted by water injection, so as to reduce the weight of the counterweight box 21 when not in use, thereby facilitating the carrying of the counterweight box 21.

[0040] Specifically, a third handle 25 is arranged on the top side of the counterweight box 21. The third handle 25 can facilitate the use of the counterweight box 21.

[0041] Specifically, the liquid injection port 23 is arranged on the top side of the counterweight box 21. The counterweight mechanism 2 is arranged on the side wall of the counterweight box 21.

[0042] Two limiting holes 11 are provided at one end of the telescopic measuring rod 1 near the counterweight box 21, and the two limiting holes 11 are spaced apart along the length of the telescopic measuring rod 1; the first fixing member 4 includes a housing 41 and two studs 42, the housing 41 is provided on one side of the counterweight box 21, and a limiting through hole 43 is provided between the housing 41 and the counterweight box 21; the housing 41 has two first threaded through holes 44, and the two first threaded through holes 44 are respectively connected to the limiting through holes 43; one stud 42 is threaded to one of the first threaded through holes 44, and the other stud 42 is threaded to the first threaded through hole 44; one end of the telescopic measuring rod 1 with two limiting holes 11 is used to pass through the limiting through hole 43, so that one stud 42 is sequentially threaded to one of the first threaded through holes 44 and one of the limiting holes 11, and the other stud 42 is sequentially threaded to the other first threaded through hole 44 and the other limiting hole 11, thereby fixing the relative position of the telescopic measuring rod 1 and the counterweight box 21. The user passes one end of the telescopic measuring rod 1 with the limiting hole 11 through the limiting through hole 43 so that the end of the telescopic measuring rod 1 with the limiting hole 11 is flush with the bottom side of the counterweight box 21. Align the two limiting holes 11 and the two first threaded through holes 44, and then rotate the two studs 42 to fix the telescopic measuring rod 1 and the housing 41.

[0043] Each stud 42 has a first handle at the end furthest from the counterweight box 21.

[0044] The floating mechanism 3 includes a second fixing member 5 and a float 31. The float 31 has a connecting through hole 32 along its thickness, through which the telescopic measuring rod 1 passes. The second fixing member 5 is located on one side of the float 31. When the telescopic measuring rod 1 passes through the connecting through hole 32 and the float 31 floats on the water surface, the second fixing member 5 fixes the relative position of the float 31 and the telescopic measuring rod 1. Since the second fixing member 5 floats on the water surface via the float 31, and after fixing the float 31 and the telescopic measuring rod 1, accurate depth data can be determined simply by observing the scale aligned with the side of the float 31 facing away from the second fixing member 5.

[0045] The second fixing component 5 includes a connecting pipe 51, a pressure plate 52, and a screw 53. One end of the connecting pipe 51 is connected to the float plate 31, and the connecting pipe 51 is connected to the connecting through hole 32. The telescopic measuring rod 1 passes through the connecting pipe 51. The pressure plate 52 is disposed inside the connecting pipe 51, and a second threaded through hole 54 is opened in the pipe wall of the connecting pipe 51. The screw 53 is located outside the connecting pipe 51, and one end of the screw 53 is threaded to the second threaded through hole 54 and extends into the connecting pipe 51 to connect to the pressure plate 52.

[0046] A second handle is provided outside the connecting pipe 51, and the second handle is connected to the end of the screw 53 away from the pressure plate 52.

[0047] Specifically, both the first and second handles are round handles.

[0048] The side of the pressing plate 52 away from the screw rod 53 and the side of the connecting pipe 51 away from the second threaded hole 54 are provided with friction layers 55. The telescopic measuring rod 1 passes between the two friction layers 55, and a user rotates the second handle to pass through the screw rod 53, so that the two friction layers 55 clamp the telescopic measuring rod 1. The two friction layers 55 can avoid slippage between the telescopic measuring rod 1 and the second fixing part 5 due to water.

[0049] The above merely describes preferred embodiments of the present application, and does not limit the patent scope of the present application. Any equivalent structural transformation, direct / indirect application in other related technical fields, or the like, made under the inventive concept of the present application, and based on the content of the present application specification and drawings, is included in the patent protection scope of the present application.
