Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of water conservancy and hydropower, and particularly relates to a water conservancy and hydropower water level benchmark. Background Art
[0002] Water conservancy and hydropower mainly involve the planning, design, construction, and management of large and medium-sized water conservancy and hydropower projects and their buildings (including dams, hydropower station buildings, gates, and intake, diversion, and discharge buildings, etc.), as well as industrial water conservancy buildings. The disciplines of water conservancy and hydropower engineering mainly study and research directions including hydrology and water resources, water environment, hydraulic structures, hydraulics and fluid dynamics, project management, etc. In water conservancy and hydropower technology, in order to avoid disasters caused by too high water levels, it is necessary to use a water level benchmark to observe the rise and fall of the water level.
[0003] However, the lengths of traditional water level benchmarks are mostly fixed lengths, resulting in a fixed measurement range. Moreover, the water level benchmarks are long-term soaked in water, and impurities in the water will adhere to the water level benchmarks. With the rise and fall of the water level, a large amount of dirt will adhere to the water level benchmarks, which will affect the water level reading. Content of the Utility Model
[0004] The purpose of the utility model is to provide a water conservancy and hydropower water level benchmark to solve at least any one of the problems raised in the above background art.
[0005] To achieve the above purpose, the utility model provides the following technical solution: A water conservancy and hydropower water level benchmark, including a benchmark body and a cleaning component. The benchmark body includes a main benchmark, a mounting benchmark, and a rod cap. A benchmark fixing ring is provided around the top wall of the main benchmark and the mounting benchmark near the edge. A plurality of jacks are equidistantly arranged around the inner side wall of the benchmark fixing ring on the top walls of the main benchmark and the mounting benchmark. Fixing ring grooves matching the benchmark fixing rings are provided around the bottom wall of the mounting benchmark and the rod cap near the edge. Plug rods matching the jacks are provided on the bottom walls of the mounting benchmark and the rod cap. The cleaning component includes two fixed half-rings and two cleaning sponges. The two cleaning sponges are respectively arranged on the inner side walls of the two fixed half-rings. One end of the two fixed half-rings is connected by a hinge, and a threaded sleeve is respectively provided at the middle position of the side walls at the other end of the two fixed half-rings. The two threaded sleeves are threadedly connected by a threaded rod. A connecting rod is provided at the middle position of the outer wall of one of the fixed half-rings, and a connecting rod is provided at both ends of the outer wall of the other fixed half-ring near the two ends. Floating balls are provided at one end of the three connecting rods. A fixed base is provided at the bottom of the main benchmark. A limiting ring is provided near the top position of the outer side wall of the rod cap. Scale lines are provided on the outer walls of the main benchmark and the mounting benchmark.
[0006] Preferably, the length ratio of the main benchmark to the mounting benchmark is 1:1.5 - 1:1.7.
[0007] Preferably, after the two fixed semi - rings are closed, the two cleaning sponges form a ring that fits the outer wall of the main benchmark.
[0008] Preferably, the main benchmark and the benchmark fixing rings on the additional benchmark have the same specifications, and the additional benchmark and the insertion rods on the rod cover have the same specifications.
[0009] Preferably, the length of the insertion rod is 15 - 20 cm.
[0010] Preferably, the main benchmark and the additional benchmark have the same diameter.
[0011] The beneficial effects of the present utility model are as follows:
[0012] 1. The staff aligns the insertion rod at the bottom of the additional benchmark with the jack and the benchmark fixing ring on the main benchmark, and then inserts it into the jack and the benchmark fixing ring, then the installation of the water level benchmark can be completed, increasing the length of the water level benchmark. By increasing the length of the water level benchmark, the measurement range of the water level benchmark is increased, enabling it to adapt to more rivers and lakes, greatly improving the practicability of the water level benchmark.
[0013] 2. The staff opens the two fixed semi - rings, puts them on the main benchmark or the additional benchmark, then screws the threaded rod into the two threaded sleeves to fix the fixed semi - rings tightly. The unstable water surface drives the floating ball to shake, causing the cleaning sponges in the fixed semi - rings to repeatedly squeeze and scrape the outer wall of the water level benchmark at the position, thereby cleaning the outer wall of the water level benchmark. By cleaning the dirt attached to the outer wall of the water level benchmark with the cleaning sponges, the scale lines on the water level benchmark are kept clear, avoiding affecting the water level reading.

Specific embodiments
[0023] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.
[0024] The present utility model provides a water conservancy and hydropower water level benchmark as Figures 1-8 shown, including a benchmark body and a cleaning component. The benchmark body includes a main benchmark 2, an additional benchmark 5 and a rod cap 6. Benchmark fixing rings 14 are provided on the circumferences near the edges of the top walls of the main benchmark 2 and the additional benchmark 5. A plurality of jacks 13 are equidistantly provided on the positions of the top walls of the main benchmark 2 and the additional benchmark 5 near the inner side walls of the benchmark fixing rings 14. Fixing ring grooves 17 matching the benchmark fixing rings 14 are provided on the circumferences near the edges of the bottom walls of the additional benchmark 5 and the rod cap 6. Inserting rods 15 matching the jacks 13 are provided on the bottom walls of the additional benchmark 5 and the rod cap 6. The cleaning component includes two fixed semi-rings 3 and two cleaning sponges 8. The two cleaning sponges 8 are respectively provided on the inner side walls of the two fixed semi-rings 3. One ends of the two fixed semi-rings 3 are connected by a hinge 9, and a threaded sleeve 4 is respectively provided at the middle positions of the side walls of the other ends of the two fixed semi-rings 3. The two threaded sleeves 4 are threadedly connected by a threaded rod 16. A connecting rod 11 is provided at the middle position of the outer wall of one of the fixed semi-rings 3, and a connecting rod 11 is provided at each of the positions near the two ends of the outer wall of the other fixed semi-ring 3. Floating balls 10 are provided at one ends of the three connecting rods 11. A base 1 is provided at the bottom of the main benchmark 2. A limiting ring 7 is provided at a position near the top of the outer side wall of the rod cap 6. Scale lines 12 are provided on the outer walls of the main benchmark 2 and the additional benchmark 5.
[0025] During the use of the benchmark, first assemble the water level benchmark. Align the insertion rod 15 at the bottom of the additional benchmark 5 with the fixed ring groove 17, and then insert it into the jack 13 and the benchmark fixing ring 14 on the main benchmark 2 after aligning them. Add several additional benchmarks 5 according to the requirements on-site. After the addition is completed, align the insertion rod 15 at the bottom of the rod cap 6 with the fixed ring groove 17, and then insert it into the jack 13 and the benchmark fixing ring 14 on the additional benchmark 5 to complete the assembly of the water level benchmark. Then open the fixed half-ring 3, put it on the main benchmark 2 or the additional benchmark 5, and screw the threaded rod 16 into the two threaded sleeves 4 to complete the installation of the fixed half-ring 3, making the cleaning sponge 8 stick to the outer wall of the main benchmark 2. After the assembly is completed, fix and install the water level benchmark at the water level measurement point through the base 1. Due to the buoyancy of the floating ball 10, it will drive the fixed half-ring 3 to float to the water surface. The bottom of the fixed half-ring 3 is approximately the water level position. Since the water surface is not stable and will often shake under the action of the wind, the floating ball 10 will drive the fixed half-ring 3 to shake as the water surface shakes, causing the cleaning sponge 8 to shake, and repeatedly scrape the outer wall of the water level benchmark where the cleaning sponge 8 is located, thereby cleaning the outer wall of the water level benchmark, facilitating the staff to observe the water level through the scale line 12.
[0026] The length ratio of the main benchmark 2 to the additional benchmark 5 is 1:1.5 - 1:1.7. The benchmark fixing rings 14 on the main benchmark 2 and the additional benchmark 5 have the same specifications. The insertion rods 15 on the additional benchmark 5 and the rod cap 6 have the same specifications. The length of the insertion rod 15 is 15 - 20 cm. The main benchmark 2 and the additional benchmark 5 have the same diameter.
[0027] The benchmark fixing rings 14 on the main benchmark 2 and the additional benchmark 5 have the same specifications. The insertion rods 15 on the additional benchmark 5 and the rod cap 6 have the same specifications, which is convenient for adding to the water level benchmark. The limiting ring 7 on the rod cap 6 can limit the fixed half-ring 3 sleeved on the water level benchmark to prevent it from detaching from the water level benchmark. The main benchmark 2 and the additional benchmark 5 have the same diameter, making the outer walls of the two after assembly flat and facilitating the movement of the fixed half-ring 3 after installation.
[0028] After the two fixed half-rings 3 are closed, the two cleaning sponges 8 form a ring that fits the outer wall of the main benchmark 2.
[0029] The two cleaning sponges 8 stick to the outer wall of the main benchmark 2. When the water surface fluctuates, the floating ball 10 will drive the fixed half-ring 3 to shake as the water surface shakes, causing the cleaning sponge 8 to shake. The cleaning sponge 8 will squeeze and scrape the outer wall of the water level benchmark, achieving the effect of cleaning the outer wall of the water level benchmark.
[0030] Finally, it should be noted that the above are only the preferred embodiments of the present utility model and are not used to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or perform equivalent replacements on some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
