Description

Technical Field

[0001] The utility model relates to the technical field of hydrological measurement equipment, and particularly relates to a hydrological measuring rod. Background Art

[0002] A hydrological measuring rod is a kind of benchmark for measuring the water depth of a water body, and is also used to fix various current meters to facilitate the flow measurement work at each measuring point on the vertical line. It is widely used in the field of hydrological information measurement. A common hydrological measuring rod is a vertical measuring rod, and the outer side of the rod body is marked with measuring scales. When in use, an operator inserts the hydrological measuring rod into the water body and measures the water depth by reading the measuring scales.

[0003] During the use of the existing hydrological measuring rod, most of them can only support the measurement of the water depth. However, due to the different impurities or other substances contained in different water areas, the staff needs to measure the water pressure at the same depth of the current water area additionally, which results in the situation that the staff needs to repeat the work. Content of the Utility Model

[0004] The purpose of the utility model is to provide a hydrological measuring rod aiming at the deficiencies of the prior art to solve the problems put forward in the background art.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: A hydrological measuring rod includes a measuring rod, the bottom end of the measuring rod is fixedly connected with a measuring head, and the appearance of the measuring head is an inverted cone. A bolt is detachably connected to the upper and lower parts of the surface of the measuring rod respectively. A liquid level pressure gauge is detachably connected to the surface of the measuring rod through the bolt. A rubber gasket is detachably connected to the bottom of the liquid level pressure gauge and above the screw hole. A locking groove is formed on the inner surface of the liquid level pressure gauge.

[0006] Preferably, the locking groove is formed on the left and right sides of the bottom inner wall of the liquid level pressure gauge, and a locking shaft is slidably connected to the inside of the locking groove, which maximally strengthens the control ability of the overall device and ensures the practicability of the overall device.

[0007] Preferably, a spring is fixedly connected to the top of the locking shaft, and a hinge is hinged to the end of the locking shaft, which effectively strengthens the stability of each component and at the same time strengthens the supporting force of the overall device.

[0008] Preferably, a pressing frame is installed on the bottom surface of the hinge, and the hinge is located on the upper surfaces of the left and right sides of the pressing frame, and the hinge is directly above the rubber gasket, which better protects the use of the overall device from being affected and strengthens the practicality of operating the overall device.

[0009] Preferably, a limiting tenon is provided on the inner surface of the lock shaft and extends into the interior of the lock groove. The lock shaft is slidably clamped inside the lock groove through the limiting tenon, which better enhances the balance of the overall device and effectively improves the flexibility of the overall device.

[0010] Preferably, scales are provided on the side surface of the measuring rod and the surface of the liquid level pressure gauge. The scale of the liquid level pressure gauge is located on the front surface of the liquid level pressure gauge, and the scale of the measuring rod is located on the side surface of the measuring rod, which more effectively enhances the operability of the overall device and ensures the firmness and stability during use.

[0011] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0012] For this hydrological measuring rod, the rubber gasket is compacted and fixed by the pressing frame so that the rubber gasket is installed and sealed at the bottom of the liquid level pressure gauge. The lock shaft slides and is limited inside the lock groove under the matching of the hinge to limit the height of the pressing frame. Then, the rubber gasket is matched with the liquid level pressure gauge to synchronously measure the water quality density using water pressure, thereby achieving flexible control of the overall device, enhancing the practical performance of the overall device, improving the defect of the existing hydrological measuring rod for single-depth measurement, and increasing the effect of synchronously measuring the water level and water pressure values.

[0020] As Figures 1-4 shown, a kind of hydrological measuring rod in this embodiment includes a measuring rod 1. A measuring head 2 is fixedly connected to the bottom end of the measuring rod 1, and the appearance of the measuring head 2 is an inverted cone. A bolt 3 is detachably connected to both the upper and lower parts of the surface of the measuring rod 1 respectively. A liquid level pressure gauge 4 is detachably connected to the surface of the measuring rod 1 through the bolt 3. The liquid level pressure gauge 4 is detachably connected by means of the bolt 3. The liquid level pressure gauge 4 is a prior art and has a water inlet itself. During hydrological monitoring, river water can enter it, and the pressure situation can be calculated by means of the movement of the inherent liquid inside. Relatively speaking, it is necessary for the water level to be relatively stable to take readings. A rubber gasket 5 is detachably connected to the bottom of the liquid level pressure gauge 4 and above the screw hole. A locking groove 10 is formed on the inner surface of the liquid level pressure gauge 4. The height position of the locking shaft 8 is restricted through the locking groove 10, and then the rubber gasket 5 is clamped.

[0021] Furthermore, the locking grooves 10 are opened on the left and right sides of the bottom inner wall of the liquid level pressure gauge 4, and a locking shaft 8 is slidably connected to the inside of the locking grooves 10. By using the locking grooves 10 and the locking shaft 8 in a matching manner, the rubber gasket 5 is clamped and sealed.

[0022] Furthermore, a spring 9 is fixedly connected to the top of the locking shaft 8, and a hinge 7 is hinged to the end of the locking shaft 8. The spring 9 provides a pulling force for the locking shaft 8 to prevent the locking shaft 8 from falling off.

[0023] Furthermore, a pressing frame 6 is installed on the bottom surface of the hinge 7, and the hinge 7 is located on the upper surfaces of the left and right sides of the pressing frame 6, and the hinge 7 is directly above the rubber gasket 5. The hinge 7 is used to assist the locking shaft 8 to be clamped inside the locking groove 10.

[0024] Furthermore, a limiting tenon is formed on the inner surface of the locking shaft 8 and extends into the inside of the locking groove 10. The locking shaft 8 is slidably clamped inside the locking groove 10 through the limiting tenon. By changing the position of the locking shaft 8, the pressing frame 6 is controlled to press the rubber gasket 5.

[0025] Furthermore, scales are provided on the side surface of the measuring rod 1 and the surface of the liquid level manometer 4. The scale of the liquid level manometer 4 is located on the front surface of the liquid level manometer 4, and the scale of the measuring rod 1 is located on the side surface of the measuring rod 1. The scales facilitate the staff to take readings and more easily distinguish the depth of the current water area and the water pressure value.

[0026] The usage method of this embodiment is as follows: When in use, please refer to Figures 1-4 , first, the staff needs to manually install the liquid level manometer 4 on the surface of the measuring rod 1. Before installation, the staff manually injects a certain amount of clear water into the interior of the hydraulic pipe 4, and then installs the pre-prepared rubber gasket 5 at the bottom of the liquid level manometer 4. When installing the rubber gasket 5, the staff manually places the rubber gasket 5 at the bottom of the liquid level manometer 4, and then manually presses the pressing frame 6 downward. When the pressing frame 6 is pressed, with the flexibility of the hinge 7, the bottom end of the locking shaft 8, with the assistance of the hinge 7, pulls the spring 9, and at the same time, the inner surface of the locking shaft 8 slides and displaces inside the locking groove 10 and is clamped at the inner bottom end of the locking groove 10. At the same time, the reset performance of the spring 9 drives the locking shaft 8 to be tightly fixed inside the locking groove 10, and then the pressing frame 6 compacts the rubber gasket 5. Finally, bolts 3 are used to install the head and tail ends of the liquid level manometer 4 on the surface of the measuring rod 1, and then the measuring rod 1 is put into the water area at the predetermined position. Readings are taken through the scale on the surface of the measuring rod 1 to obtain the data of the water area depth, and according to the scale at which the clear water in the liquid level manometer 4 rises, the water pressure value of the water depth is obtained. Then, through reverse conversion, the water density of the current water area can be roughly calculated.

[0027] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
