Description

Technical Field

[0001] This utility model relates to the technical field of auxiliary equipment for water conservancy engineering measurement, and in particular to a portable auxiliary support for water level measurement in water conservancy engineering. Background Technology

[0002] In water conservancy project construction and hydrological monitoring, water level measurement is a fundamental and crucial task, and the accuracy of the measurement data directly affects the scientific nature of decisions such as project design and flood control scheduling. Currently, on-site water level measurement in water conservancy projects mostly relies on supports to assist measuring instruments or measuring lines. However, existing measuring supports generally suffer from poor portability, weak adaptability, and insufficient stability.

[0003] However, most existing measuring supports suffer from a lack of portability: some supports are integral fixed structures that cannot be folded and stored, and are large and heavy, making it extremely inconvenient for staff to carry and transport them in complex outdoor terrains such as mountains and muddy riverbanks; even the few supports with folding functions generally suffer from complex folding structure designs and cumbersome folding processes, and the effect of reducing volume after folding is limited. At the same time, some components cannot be quickly separated, which can easily cause interference, further reducing portability. Utility Model Content

[0004] The purpose of this utility model is to solve the problems existing in the prior art by proposing a portable auxiliary support for water level measurement in water conservancy projects.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a portable auxiliary support for water level measurement in water conservancy projects, comprising a support recess, a base plate rotatably mounted on the outer wall of the support recess, a first rotating shaft rod rotatably mounted through one end of the base plate, a hexagonal seat above the support recess, elliptical holes through both ends of the support recess, a second rotating shaft rod slidably mounted inside the two sets of elliptical holes, two sets of movable plates rotatably mounted on the outer wall of the first rotating shaft rod, a threaded seat mounted on the upper end of the support recess, a vertical screw rod threadedly connected inside the threaded seat, and a rotating head rotatably mounted on the lower end of the hexagonal seat.

[0006] Preferably, the upper parts of both sets of movable plates are rotatably mounted on the second rotating shaft, and the upper and lower side walls of the two sets of movable plates are in contact with the two ends of the support recess and the base plate, respectively.

[0007] Preferably, the upper portion of the vertical screw is threaded inside the rotating head.

[0008] Preferably, a concave seat is installed on one side of the support recess, and both ends of the concave seat are provided with elongated holes.

[0009] Preferably, the inner two side walls of the concave seat are in contact with the two ends of the second rotating shaft, and a portion of each of the two sets of hexagonal bolts is threaded into the two sets of threaded holes.

[0010] Preferably, a fixing plate is welded to one end of the recessed base, and a limiting cone rod is inserted through the upper end of the fixing plate.

[0011] Preferably, a mounting plate is welded to one end of the hexagonal base.

[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. In this utility model, the core structure can be quickly folded by the rotational cooperation of the support recess and the base, and the linkage design of the movable plate and the double rotating shaft.

[0016] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0017] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0018] Example 1: As Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, this utility model provides a portable auxiliary support for water level measurement in water conservancy projects, including a support recess 1, a recessed base 2 rotatably mounted on the outer wall of the support recess 1, a first rotating shaft 3 rotatably mounted through one end of the recessed base 2, a hexagonal seat 4 above the support recess 1, elliptical holes 6 through both ends of the support recess 1, a second rotating shaft 7 slidably mounted inside the two sets of elliptical holes 6, two sets of movable plates 8 rotatably mounted on the outer wall of the first rotating shaft 3, a threaded seat 11 mounted on the upper end of the support recess 1, a vertical screw 12 threadedly connected inside the threaded seat 11, a rotating head 13 rotatably mounted on the lower end of the hexagonal seat 4, the upper parts of the two sets of movable plates 8 rotatably mounted on the second rotating shaft 7, the upper and lower side walls of the two sets of movable plates 8 respectively contacting the two ends of the support recess 1 and the recessed base 2, the upper part of the vertical screw 12 threadedly mounted inside the rotating head 13; and a mounting plate 5 welded to one end of the hexagonal seat 4.

[0019] The specific settings and functions of this embodiment are described in detail below. The support recess 1 adopts an arc-shaped groove structure, and its outer wall is rotatably fitted with the recess base 2. This rotatable fit provides the core foundation for folding, allowing the support recess 1 to be flipped and folded relative to the recess base 2, ultimately fitting against the surface of the recess base 2, fundamentally reducing the longitudinal space occupied by the bracket. A first rotating shaft 3 is rotatably installed through one end of the recess base 2, serving as the rotation fulcrum of the movable plate 8 and providing stable support for the folding linkage. A hexagonal seat 4 is provided above the support recess 1 for assembling measurement-related components. Its hexagonal structure prevents the components from rotating circumferentially and flips synchronously with the support recess 1 during folding, avoiding interference with other components. Both ends of the support recess 1 are provided with elliptical holes 6, which extend along the length of the support recess 1, providing travel space for the sliding of the second rotating shaft 7. The second rotating shaft 7 is slidably installed inside both sets of elliptical holes 6. Two sets of symmetrically distributed movable plates 8 are rotatably installed on the outer wall of the first rotating shaft 3. The upper part of the structure is rotatably mounted on the second pivot rod 7, and the upper sidewall of the movable plate 8 is attached to both ends of the support recess 1, and the lower sidewall is attached to both ends of the recess base 2, forming a complete folding linkage structure. When folding is required, by sliding the second pivot rod 7 to the end of the elliptical hole 6, the two sets of movable plates 8 can be rotated around the first pivot rod 3, and finally attached to the surface of the recess base 2. At the same time, the support recess 1 is flipped to attach to the recess base 2, completing the folding and storage of the core structure. In addition, a threaded seat 11 is installed at the upper end of the support recess 1, and a vertical screw 12 is threadedly connected inside the threaded seat 11. A rotating head 13 is rotatably mounted at the lower end of the hexagonal seat 4, and the upper part of the vertical screw 12 is threaded inside the rotating head 13. This structural design takes into account both the initial positioning during use and the quick separation during folding. When folding, the vertical screw 12 can be screwed to make it spiral out of the threaded seat 11 and the rotating head 13 simultaneously, realizing the quick separation of the three, avoiding interference between parts, ensuring smooth folding, and further improving the efficiency of portable disassembly.

[0020] One end of the hexagonal base 4 is welded with a mounting plate 5, which extends horizontally and has multiple sets of evenly distributed mounting holes on its surface to facilitate the installation of the water level measuring instrument.

[0021] Example 2: Figure 1 , Figure 2 and Figure 3 As shown, a concave seat 9 is installed on one side of the support recess 1. Both ends of the concave seat 9 are provided with elongated holes 17. Hexagonal bolts 10 are inserted into the two sets of elongated holes 17. Both ends of the second rotating shaft 7 are provided with threaded holes 16. The inner side walls of the concave seat 9 are in contact with the two ends of the second rotating shaft 7. Parts of the two sets of hexagonal bolts 10 are threaded into the two sets of threaded holes 16. A fixing plate 14 is welded to one end of the concave base 2. A limiting cone rod 15 is inserted through the upper end of the fixing plate 14.

[0022] The overall effect of this embodiment is as follows: a concave seat 9 is installed on one side of the support recess 1. The concave seat 9 adopts a U-shaped groove structure, which can form a limiting fit on the end of the second rotating shaft 7. Both ends of the concave seat 9 are provided with elongated holes 17, which are set along the length of the concave seat 9 to adapt to the sliding adjustment stroke of the second rotating shaft 7. Hexagonal bolts 10 are inserted into both sets of elongated holes 17. Correspondingly, both ends of the second rotating shaft 7 are provided with threaded holes 16. The inner side walls of the concave seat 9 are in close contact with the ends of the second rotating shaft 7. Parts of the two sets of hexagonal bolts 10 are threaded into the two sets of threaded holes 16. When the folding structure of Embodiment 1 is unfolded to the working state, after the second rotating shaft 7 slides to the corresponding support position, by tightening the hexagonal bolts 10, the second rotating shaft 7 can be firmly fixed in the current position by using the thread locking force of the bolts and the threaded holes 16, thereby locking the support structure formed by the movable plate 8, the support recess 1, and the concave base 2, preventing the second rotating shaft 7 from sliding and causing the folding structure to loosen during use.

[0023] In addition, a fixing plate 14 is welded to one end of the concave base 2. The fixing plate 14 adopts a thickened steel plate structure to increase the contact area with the ground and improve the placement stability. A limiting cone rod 15 is inserted through the upper end of the fixing plate 14. The lower end of the limiting cone rod 15 adopts a sharp cone structure. When in use, the limiting cone rod 15 can be inserted vertically into the ground. Through the interlocking action of the cone rod and the soil, it works with the fixing plate 14 to form a stable limit on the concave base 2, preventing the entire support from tipping over or shifting. It is especially suitable for soft ground environments in the field, further ensuring the stability of the measurement process. At the same time, the limiting cone rod 15 adopts a plug-in design. When folding and storing, it can be quickly pulled out from the fixing plate 14 and stored separately without increasing the folding volume, balancing the fixing effect and portability.

[0024] The usage and working principle of this device are as follows: First, place the concave base 2 in a suitable position, then pass the limiting cone rod 15 through the fixing plate 14 and insert it into the ground; second, when unfolding the folding structure, flip the supporting concave base 1 so that it rotates relative to the concave base 2 to the working position, slide the second rotating shaft rod 7 to the support position of the elliptical hole 6, so that the two sets of movable plates 8, the supporting concave base 1, and the concave base 2 form a stable support structure, and thread the vertical screw rod 12 into the threaded seat 11 and the rotating head 13 to achieve initial positioning; then, after completing the fixed limiting, tighten the hexagonal bolts 10 on the concave seat 9. Lock and fix the second rotating shaft 7, then insert the limiting cone 15 into the ground, and use the fixing plate 14 to form a stable limit on the concave base 2; then, assemble the corresponding measuring components on the mounting plate 5, and the water level measurement operation can be carried out; after the measurement is completed, disassemble the measuring components, pull out the limiting cone 15, loosen the hexagonal bolt 10 and the vertical screw 12 and separate them, slide the second rotating shaft 7 to the end of the elliptical hole 6 to drive the movable plate 8 to fit against the concave base 2, flip the support concave base 1 to fit against the concave base 2 to complete the folding, and finally store and transport the disassembled parts together with the folded main body.

[0025] The above are merely preferred embodiments of this utility model and are not intended to limit the utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of this utility model without departing from the technical solution of this utility model shall still fall within the protection scope of this utility model.
