Description

Technical Field

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

[0002] Currently, in engineering management sites, especially water conservancy projects, water level gauges are indispensable. The main function of water level gauges is to monitor the water level of specific pools in real time, thereby achieving effective prevention.

[0003] For example, CN218443898U discloses a multifunctional measuring ruler for water conservancy projects, including a right-angle ruler. The right-angle ruler is divided into a horizontal ruler and a vertical ruler that intersect in an L-shape. The horizontal ruler and the vertical ruler can be folded. A protractor is provided on the inner side of the included angle of the right-angle ruler. The protractor can be folded. An LED light is provided at the intersection of the horizontal ruler and the vertical ruler. A vertical calibration device is provided on the side of the horizontal ruler near the protractor. A laser light is provided on the end of the horizontal ruler away from the vertical ruler. A horizontal calibration device is provided on the side of the vertical ruler near the protractor. A vernier caliper is provided on the end of the vertical ruler away from the horizontal ruler.

[0004] This patent integrates various functions such as ruler, protractor, level, plumb bob, caliper, lighting and laser, basically meeting all the needs of measurement without changing tools, avoiding the safety hazards caused by frequent tool changes, and improving work efficiency. The horizontal and vertical rulers and protractor of this measuring ruler can be folded. However, this measuring ruler is not convenient to fix in the scene of bridges, dams and so on, and the installation is relatively cumbersome, with low practicality. Utility Model Content

[0005] The purpose of this utility model is to provide a multifunctional hydraulic measuring ruler to solve the problems mentioned in the background art, such as the measuring ruler being inconvenient to fix in bridges, dams and other scenarios, the installation being cumbersome and the practicality being low.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a multifunctional hydraulic measuring ruler, including a ruler body. A fixing mechanism is fixedly connected to the rear end of the ruler body. The fixing mechanism includes a fixing column, which is fixedly connected to the rear end of the ruler body. A connecting column is fixedly connected to one end of the fixing column, and a fixing nut is fixedly connected to one end of the connecting column. The inner cavity of the fixing nut is provided with a thread. A compression plate is fixedly connected to the inner cavity of the connecting column. Several compression plates are symmetrically arranged around the circumference. A retainer is movably connected to the outer side of the compression plate. A fixing groove is opened in the inner cavity of the connecting column.

[0008] Furthermore, a protective component is fixedly connected to the outer side of the ruler body. The protective component includes a lower protective plate, which is fixedly connected to one end of the ruler body. An upper protective plate is fixedly connected to the end of the ruler body away from the lower protective plate, and a bottom protective plate is fixedly connected to the bottom end of the ruler body.

[0009] Furthermore, two sets of fixing nuts are symmetrically arranged, and the two sets of fixing nuts are respectively arranged on both sides of the ruler body.

[0010] Furthermore, the upper and lower protective plates have the same shape as the two ends of the ruler body, and the upper and lower protective plates are made of silicone to protect the ruler body.

[0011] Furthermore, the bottom protective plate has the same shape as the bottom of the ruler body, and the bottom protective plate is made of silicone to protect the ruler body.

[0012] Furthermore, the surface of the ruler is provided with scale markings, which are evenly distributed along the length of the ruler.

[0013] This utility model has the following beneficial effects:

[0014] I. This utility model is equipped with a fixing mechanism. The fixing nut is aligned with the target fixing point (such as bridge pre-embedded bolts, dam supports, etc.). By rotating the fixing nut, its thread engages with the external bolt, achieving initial fixing. The extrusion plate expands outward under the action of the fixing device, tightly fitting the inner wall of the fixing groove to form a secondary lock and prevent loosening. During this process, the two fixing nuts are symmetrically distributed, and the force is evenly distributed, avoiding tilting or falling off caused by single-point fixing. Furthermore, the dual fixing mechanism of threaded connection and extrusion plate can adapt to fixing points of different diameters, enhancing versatility. The dual fixing of threaded connection and extrusion plate solves the problem of complicated installation and improves stability.

[0015] Second, based on the above-mentioned beneficial effects, protective components are also set up. The upper and lower protective plates made of silicone absorb external impact forces (such as collisions during transportation) to prevent the ruler from deforming or the scale from wearing off. The silicone seals both ends and the bottom of the ruler to prevent water vapor and mud from entering the internal structure, making it suitable for long-term outdoor or underwater use. The bottom protective plate directly contacts the ground or rough surface to reduce friction and keep the bottom of the ruler flat. With comprehensive protection from silicone material, the life of the ruler is extended and it can adapt to the harsh environment of water conservancy projects. Attached Figure Description

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] To make the objectives, technical solutions, and advantages of this utility model clearer, the embodiments of this utility model will be described in further detail below with reference to the accompanying drawings.

[0024] Please see Figures 1 to 3 As shown, this utility model is a multifunctional hydraulic measuring ruler, including a ruler body 1. A fixing mechanism 3 is fixedly connected to the rear end of the ruler body 1. The fixing mechanism 3 includes a fixing column 31, which is fixedly connected to the rear end of the ruler body 1. A connecting column 32 is fixedly connected to one end of the fixing column 31, and a fixing nut 33 is fixedly connected to one end of the connecting column 32. The inner cavity of the fixing nut 33 is provided with a thread. A pressing plate 34 is fixedly connected to the inner cavity of the connecting column 32. Several pressing plates 34 are symmetrically arranged around the circumference. A fixing device 35 is movably connected to the outer side of the pressing plate 34. A fixing groove 36 is opened in the inner cavity of the connecting column 32.

[0025] For example, the fixing mechanism 3, through the combined design of threaded connection and compression plate 34, can quickly and firmly fix the measuring ruler in complex scenarios such as bridges and dams, avoiding the cumbersome installation problem of traditional measuring rulers and improving installation efficiency and stability.

[0026] Two sets of fixing nuts 33 are symmetrically arranged, and the two sets of fixing nuts 33 are respectively arranged on both sides of the ruler body 1;

[0027] For example, the double fixing nut 33 design enhances the balance and load-bearing capacity of the fixing mechanism 3, ensuring that the measuring ruler remains stable in harsh environments (such as water flow impact and wind influence), and reducing measurement errors.

[0028] The surface of the ruler 1 is provided with scale markings, which are evenly distributed along the length of the ruler 1.

[0029] For example, the scale markings are evenly distributed, making it easy to read data such as water level and distance directly, improving measurement accuracy and efficiency without the need for additional tools.

[0030] Working principle: Align the fixing nut 33 with the target fixing point (such as bridge pre-embedded bolts, dam supports, etc.), and rotate the fixing nut 33 so that its thread engages with the external bolt to achieve initial fixing. The extrusion plate 34 expands outward under the action of the fixing device 35 and fits tightly against the inner wall of the fixing groove 36 to form a secondary lock and prevent loosening. During this process, the two fixing nuts 33 are symmetrically distributed and evenly stressed, avoiding tilting or falling off caused by single-point fixing. Furthermore, the dual fixing mechanism of threaded connection and extrusion plate 34 can adapt to fixing points of different diameters and enhance versatility.

[0031] This step solves the problem of complicated installation by using both threads and extrusion plates 34 for double fixing, thus improving stability.

[0032] Please see Figure 1-2 As shown, this embodiment, based on the above embodiment, further includes a protection component 2.

[0033] A protective component 2 is fixedly connected to the outer side of the ruler body 1. The protective component 2 includes a lower protective plate 21, which is fixedly connected to one end of the ruler body 1. An upper protective plate 22 is fixedly connected to the end of the ruler body 1 away from the lower protective plate 21. A bottom protective plate 23 is fixedly connected to the bottom end of the ruler body 1.

[0034] For example, the protective component 2 fully covers the vulnerable parts of the ruler body 1 (such as both ends and the bottom) to prevent bumps, corrosion or wear and extend the service life of the measuring ruler.

[0035] The upper protective plate 22 and the lower protective plate 21 have the same shape as the two ends of the ruler 1. The upper protective plate 22 and the lower protective plate 21 are made of silicone to protect the ruler 1.

[0036] For example, the upper protective plate 22 and the lower protective plate 21 are made of liquid silicone (LSR) or high-temperature vulcanized silicone (HTV), which have higher cross-linking density and anti-aging properties, making them suitable for long-term underwater or humid environments. Fiberglass mesh or polyester fiber skeleton is embedded inside the silicone protective plate to improve tear resistance (≥10kN / m) and prevent damage caused by external impact. A lip sealing structure (such as a double sealing ring) is designed at the contact edge between the protective plate and the ruler body, and waterproof sealant (such as silicone sealant) is applied to the joints to ensure IP67 waterproof rating (no water ingress at 1 meter underwater for 30 minutes). The silicone material has flexibility and impact resistance, effectively buffering external impacts while being waterproof and moisture-proof, making it suitable for humid environments in water conservancy projects.

[0037] The bottom protective plate 23 has the same shape as the bottom of the ruler 1. The bottom protective plate 23 is made of silicone to protect the ruler 1.

[0038] For example, the bottom protective plate 23 has a hardness range of 50-70 Shore A, a temperature range of -40℃ to +150℃, and is resistant to ozone aging: ≥50pphm, no cracks after 500 hours (GB / T 7762-2014), UV aging: UVA-340nm, color difference ΔE≤3 after 500 hours (GB / T 16422.3-2014), and damp heat aging: 85℃ / 85% RH, hardness change ≤±5 Shore A after 1000 hours. The bottom protective plate 23 further prevents wear or corrosion on the bottom of the ruler 1, especially when placed on rough surfaces (such as rock and concrete).

[0039] Working principle: The upper and lower protective plates 21 made of silicone absorb external impact (such as collisions during transportation) to prevent the ruler 1 from deforming or the scale from wearing off. The silicone seals both ends and the bottom of the ruler 1 to prevent water vapor and mud from entering the internal structure, making it suitable for long-term outdoor or underwater use. The bottom protective plate 23 directly contacts the ground or rough surface to reduce friction and keep the bottom of the ruler 1 flat. Through the comprehensive protection of silicone material, the life of the ruler 1 is extended and it can adapt to the harsh environment of water conservancy projects.

These preferred embodiments do not exhaustively describe all details, nor do they limit the utility model to the specific implementations described. Clearly, many modifications and variations can be made based on the content of this specification. This specification selects and specifically describes these embodiments to better explain the principles and practical applications of this utility model, thereby enabling those skilled in the art to better understand and utilize it. This utility model is limited only by the claims and their full scope and equivalents.
