Description

Technical Field

[0001] This utility model relates to the field of water level measurement technology, specifically a water level measuring rod. Background Technology

[0002] my country has numerous rivers, and many regions rely on nearby rivers for their production and domestic water supply. Therefore, understanding and monitoring the conditions of these water intake channels is the responsibility of every hydrological and water conservancy worker. Currently, water level measurements in enclosed or flowing water areas are mostly done by erecting long poles in the water and setting markers on the poles to measure the water depth of the river basin. However, long poles are inconvenient to move and cannot be carried, so they can only measure the water level at the same location for a long time, making it impossible to accurately determine the impact of sediment content on water depth within the river basin.

[0003] Other measuring rods, such as the telescopic measuring rod described in application number 202223317997.2, include a perpendicular handgrip and a measuring rod. While convenient for personnel to move and measure multiple points, this telescopic measuring rod lacks counterweight, making the measuring rod susceptible to buoyancy and causing measurement errors. Other measuring rods use a pull rope counterweight, which is complex to operate and prone to breakage, affecting measurement progress. Therefore, there is an urgent need to design a water level measuring rod that is easy to move and unaffected by buoyancy. Utility Model Content

[0004] The purpose of this invention is to provide a water level measuring rod to solve the problems of existing measuring rods being inconvenient to move, impossible to carry, and easily affected by buoyancy in the above-mentioned background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A water level measuring rod, comprising:

[0007] The main rod is hollow inside and has a first opening at its first end, and the axis of the main rod extends along a first direction;

[0008] A sleeve rod is movably disposed within the inner cavity of a main rod along a first direction, such that the sleeve rod has a first state and a second state. When the sleeve rod is in the first state, it is completely retracted into the inner cavity of the main rod. When the sleeve rod is in the second state, it is connected to the main rod via a limiting member, and a first end of the sleeve rod extends to the outside of the main rod along a first opening. The first end of the sleeve rod has a filling cavity inside, and the sleeve rod has a filling hole communicating with the filling cavity.

[0009] A filling barrel; the filling barrel contains several steel balls, which are used to fill the filling cavity with steel balls through the filling hole. With the above design, the water level measuring rod has a simple structure, is easy to carry, and allows hydrological and water conservancy workers to easily measure the water depth at different points in the same watershed, helping to accurately determine the sediment content within the river basin. Furthermore, the rod can be filled with steel balls, ensuring that the measuring rod is not affected by buoyancy during measurement.

[0010] Furthermore, the main rod has several limiting holes extending radially through it, and the sleeve has positioning holes extending radially through it. The positioning holes and corresponding limiting holes are locked together by limiting members to connect the sleeve to the main rod. This design allows for a rapid extension of the measuring rod's depth.

[0011] Furthermore, the filling cavity has a closable opening. This feature allows the opening to be closed after steel balls are filled into the filling cavity, preventing the steel balls from flowing out.

[0012] Furthermore, the sleeve includes multiple extension rods; the outer diameters of the multiple extension rods decrease sequentially. In the first state, the multiple extension rods are sequentially sleeved and completely housed within the inner cavity of the main rod. In the second state, the multiple extension rods are connected end-to-end, with their heads connected to the main rod via limiting members, and their tails extending along the first opening of the main rod to the outside of the main rod. The extension rod at the tail end has a filling cavity inside, and a filling hole communicating with the filling cavity is provided. This configuration increases the length of the measuring rod itself, making it suitable for different water depths.

[0013] Furthermore, adjacent extension rods are fixed together by threads or bolts.

[0014] Furthermore, the first opening is provided with a detachable first cover, and the second end of the main rod is either closed or has a second opening, which in turn has a detachable second cover. This design facilitates the storage of the sleeve rod.

[0015] Furthermore, a handle is provided at the other end of the main rod; an anti-slip layer is provided on the outer periphery of the handle. This design facilitates the handling of the measuring rod.

[0016] Furthermore, the filling barrel includes a barrel body, the upper end of which has a detachable third cover. One side of the barrel body has a short filling rod communicating with the inner cavity of the barrel, allowing steel balls inside the barrel to be filled into the sleeve rod via the short filling rod. By providing a short filling tube on the side of the barrel body for steel ball outflow, it can be directly inserted into the filling hole of the sleeve rod during filling, preventing steel balls from scattering.

[0017] Furthermore, both the main rod and the sleeve rod are equipped with reading devices. By setting these readings, water level data can be accurately read.

[0018] This invention has the following advantages over the prior art:

[0019] This utility model relates to a water level measuring rod, comprising a main rod, a sleeve rod, and a filling bucket. In the first state (when not measuring), the sleeve rod is stored inside the main rod for easy carrying. In the second state (when measuring), the sleeve rod is fixed to the main rod by a limiting member, with its first end extending out of the main rod and inserted into the water area to measure the water level. During use, the sleeve rod is pulled out and fixed with the limiting member; conversely, it is stored inside the main rod, reducing the space occupied by the measuring rod. The overall structure is simple, easy to operate, and convenient to handle and move. Hydrological and water conservancy workers can easily use this water level measuring rod to measure the water depth at different points, and can also accurately measure the water depth at fixed points, facilitating subsequent river dredging and other engineering projects. The sleeve rod can be filled with steel balls to prevent the measuring rod from being affected by buoyancy during measurement; when measuring the water depth, steel balls can be added at any time to prevent the measuring rod from floating, making the measurement more accurate.

Therefore, they should not be construed as limitations on this utility model.

[0027] Furthermore, it should be understood that, for ease of description, the dimensions of the various components shown in the accompanying drawings are not drawn to actual scale.

[0028] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined or described in one figure, it will not need to be further discussed and described in the description of the subsequent figures.

[0029] Example 1:

[0030] like Figures 1-2 As shown, this utility model provides a water level measuring rod, including: a main rod 1, a sleeve rod 2, and a filling bucket 3; the main rod 1 is hollow inside and has a first opening at its first end, and the axis of the main rod 1 extends along a first direction (the first direction is the length direction of the main rod 1); the sleeve rod 2 is movably disposed in the inner cavity of the main rod 1 along the first direction, so that the sleeve rod 2 has a first state (when not in use) and a second state (when in use); when the sleeve rod 2 is in the first state, the sleeve rod 2 is completely housed in the inner cavity of the main rod 1; when the sleeve rod 2 is in the second state, the sleeve rod 2 is connected to the main rod 1 through a limiting member 4, and the first end of the sleeve rod 2 extends to the outside of the main rod 1 along the first opening of the main rod 1. The sleeve rod 2 in this water level measuring rod can be completely housed inside the main rod 1, which is simple in structure, easy to carry, and reduces the overall space occupied by the measuring rod. During measurement, the sleeve rod 2 is simply pulled out and fixed, making it convenient to operate and suitable for measuring water depth at fixed points or different locations in enclosed or flowing water bodies, helping to accurately determine the sediment content in river basins. Furthermore, the first end of the sleeve rod 2 has a filling cavity 201, and the sleeve rod 2 has a filling hole 202 communicating with the filling cavity 201. The filling barrel 3 contains several steel balls, which are used to fill the filling cavity 201 with steel balls through the filling hole 202. The diameter of the steel balls should be smaller than the inner diameter of the sleeve rod 2. The filling hole 202 can be sealed with existing tools (such as sealing plugs) to prevent water from entering when inserted into the water body. This design effectively prevents the measuring rod from floating, and the measurement is not affected by buoyancy.

[0031] This device can measure the depth of both enclosed and flowing water. With the counterweight of steel balls, it can also accurately measure the depth in flowing water. As the depth of the water to be measured increases, steel balls can be added at any time to ensure measurement accuracy.

[0032] Specifically, the main rod 1 has several radially penetrating limiting holes 101, and the sleeve rod 2 has radially penetrating positioning holes. The positioning holes and the corresponding limiting holes 101 are locked together by limiting members 101 to achieve connection between the sleeve rod 2 and the main rod 1. Figure 1As shown, the limiting component 4 can be a bolt. The bolt passes through the limiting hole 101 and the positioning hole, and then the bolt is tightened with a nut, thereby fixing the sleeve rod 2 to the main rod 1 and extending the overall length of the measuring rod. There are multiple limiting holes 101, and the extension length of the sleeve rod 2 can be adjusted according to the actual use.

[0033] In this embodiment, the filling cavity 201 has a closable opening 203. After steel balls are filled into the filling cavity 201, this opening can be closed to prevent the steel balls from flowing out.

[0034] In this embodiment, a detachable first cover is provided corresponding to the first opening of the main rod 1. The second end of the main rod 1 is either closed or has a second opening, which has a detachable second cover. When the sleeve rod 2 is completely retracted into the main rod 1, the first opening can be closed by the first cover, and the second opening can be closed by the second cover, making it convenient to store and carry the measuring rod.

[0035] The other end of the main rod 1 is provided with a handhold; the outer periphery of the handhold is provided with an anti-slip layer 102. The above-mentioned configuration facilitates the handling of the measuring rod.

[0036] refer to Figure 2 The filling barrel 3 includes a barrel body 301, the upper end of which has a detachable third cover 302. One side of the barrel body 301 has a filling short rod 303 communicating with the inner cavity of the barrel body 301, allowing steel balls inside the barrel to be filled into the sleeve rod 2 via the filling short rod 303. By providing a filling short tube 303 on the side of the barrel body 301 for steel ball outflow, it can be directly inserted into the filling hole 202 of the sleeve rod 2 during filling, preventing steel balls from scattering.

[0037] Both the main rod 1 and the sleeve rod 2 are equipped with reading devices. Water level data can be accurately read by setting these readings.

[0038] In practical use:

[0039] When measuring water depth in enclosed or flowing water areas, operators can hold the measuring rod, loosen the first cover of the measuring rod, pull out the sleeve rod 2, and then limit it by the limiting component. The filling bucket 3 is then taken out, and steel ball counterweights are poured into the filling hole 202 of the sleeve rod 2 through the filling short rod 303. The filling hole 202 is then sealed to prevent water from entering the filling chamber. The measuring rod is then inserted into the water area to be measured, and the water depth of the current water area can be read by the scale on the main rod 1 and the sleeve rod 2.

[0040] Operators can use this measuring rod to measure water depth at different locations within a river basin, obtaining the water depth at different points. The average of these measurements provides a relatively accurate estimate of the river basin's water depth. This measuring rod has a simple structure, is easy to carry, and is suitable for both enclosed and flowing water areas, making it highly valuable for widespread application.

[0041] Example 2:

[0042] This embodiment is the same as embodiment 1 except for the following technical solutions:

[0043] When the water level to be measured is relatively deep, the sleeve rod 2 is configured as multiple sleeved extension rods; the outer diameter of the multiple extension rods decreases sequentially. In the first state, the multiple extension rods are sequentially sleeved and completely housed within the inner cavity of the main rod 1; in the second state, the multiple extension rods are connected end to end, with their heads connected to the main rod via limiting members, and their tails extending along the first opening of the main rod 1 to the outside of the main rod 1. The extension rod at the tail end has a filling cavity 201 inside, and a filling hole 202 communicating with the filling cavity 201 is opened. The filling hole 202 must be sealed before insertion into the water to prevent water from entering. Adjacent extension rods are fixed together by threads or bolts, or by other existing fixing methods.

[0044] The number of extension rods in sleeve 2 can be increased according to the water depth, and the diameter of the main rod 1 will increase accordingly. Two or more limiting holes 101 can be provided for limiting. Steel balls of various diameters can be configured; however, the diameter of the steel balls used for final measurement must be smaller than the diameter of the tail extension rod for it to be usable. This device can be used to measure the water depth in enclosed or flowing water areas. With the counterweight of the steel balls, accurate water depth measurement is also possible in flowing water.

[0045] Although 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 alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
