Description

Technical Field

[0001] The utility model relates to the technical field of measuring rods, in particular to an adjustable river depth hydrological measuring rod. Background Art

[0002] A river depth hydrographic rod is a rigid measuring rod with a base, engraved with scales and readable for measuring water depth.

[0003] Currently, the more common river depth hydrological measuring rod is a telescopic rod with adjustable length. There is a scale on the rod. When in use, the measuring rod is directly inserted into the water until the chassis on the measuring rod sinks to the bottom of the water. This is to directly read the value on the measuring rod corresponding to the horizontal plane. However, when it is dark outside, it is difficult to determine the boundary of the horizontal plane when measuring the water level using this method, and it is not easy to align the horizontal plane with the scale when reading. For this reason, we propose an adjustable river depth hydrological measuring rod to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0026] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] Reference Figure 1-5 A river depth hydrological measuring rod capable of adjustment comprises a measuring rod 1, wherein the measuring rod 1 comprises a measuring rod body 2, on which an auxiliary component 3 is arranged, the measuring rod body 2 comprises a No. 1 positioning rod 201, in which a No. 2 positioning rod 202 is slidably connected, the auxiliary component 3 comprises an indicator assembly 301, on which a limit assembly 302 is arranged.

[0028] A water inlet hole 2011 is provided on one side of the No. 1 positioning rod 201, and a filter is provided in the water inlet hole 2011 to prevent larger garbage from entering the measuring body 2. The filter is not shown in the figure. A No. 1 observation window 2012 is fixedly connected to one side of the No. 1 positioning rod 201. A No. 1 scale 2013 is provided on one side of the No. 1 positioning rod 201, and the No. 1 scale 2013 corresponds to the No. 1 observation window 2012.

[0029] A No. 2 observation window 2021 is fixedly connected to one side of the No. 2 positioning rod 202, and the observation window 2021 is made of transparent material. A No. 2 scale 2022 is provided on one side of the No. 2 positioning rod 202, and the No. 2 scale 2022 corresponds to the No. 2 observation window 2021, and the No. 2 observation window 2021 and the No. 2 scale 2022 correspond to the No. 1 observation window 2012 and the No. 1 scale 2013 respectively.

[0030] The indicator assembly 301 includes two fixed plates 3011 fixedly connected to the No. 2 positioning rod 202, and a rotating shaft 3012 is rotatably connected between the two fixed plates 3011. One end of the rotating shaft 3012 passes through the fixed plate 3011 and extends a portion thereof. A connecting rope 3013 is wound and fixed on the rotating shaft 3012, and one end of the connecting rope 3013 passes through the No. 2 positioning rod 202 and is fixedly connected to an indicator mark 3014.

[0031] The indicator mark 3014 is trapezoidal, and the length and width of the bottom of the indicator mark 3014 are the same as the length and width of the inside of the second positioning rod 202. The indicator mark 3014 needs to be painted with colored paint, and the indicator mark 3014 is made of lightweight material and can float directly on the horizontal plane.

[0032] The limiting assembly 302 includes an inner gear 3021 fixedly connected to the fixed plate 3011, an outer gear 3022 is slidably connected to the rotating shaft 3012, and the outer gear 3022 corresponds to the inner gear 3021, one end of the rotating shaft 3012 is fixedly connected to a baffle 3024, a spring 3023 is sleeved on the outer surface of the rotating shaft 3012, and the two ends of the spring 3023 are respectively fixedly connected to the baffle 3024 and the outer gear 3022.

[0033] When in use, first loosen the fastening bolts at the bottom, then pull the No. 2 positioning rod 202 to move it upward until it moves to the highest top, then turn another fastening bolt to fix the No. 2 positioning rod 202 and the No. 1 positioning rod 201. At this time, place the device in water until it is inserted into the bottom of the water. During this process, water will enter the measuring rod 1 through the water inlet hole 2011. Since water enters the measuring rod 1 through the water inlet hole 2011, even if the wind blows outside, the water level in the measuring rod 1 does not change much.

[0034] After the measuring rod 1 is straightened, the outer gear 3022 is pulled outward and the spring 3023 is squeezed until the outer gear 3022 is separated from the inner gear 3021. Then the rotating shaft 3012 can be rotated and the connecting rope 3013 can be paid out. When paying out the line, the indicator mark 3014 will fall down until the indicator mark 3014 falls on the water. Since the indicator mark 3014 is coated with paint, the horizontal plane can be directly distinguished, which allows for more intuitive data reading.

[0035] When the indicator mark 3014 falls on the water surface, the outer gear 3022 can be loosened. At this time, under the elastic force of the spring 3023, the outer gear 3022 will move in the original direction until it can no longer move. At this time, the outer gear 3022 and the outer gear 3021 are just meshed, thereby limiting the rotating shaft 3012.

[0036] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and the specification only describe the principles of the utility model. The utility model may be subject to various changes and improvements without departing from the spirit and scope of the utility model. These changes and improvements fall within the scope of the utility model to be protected. The scope of protection claimed by the utility model is defined by the attached claims and their equivalents.
