Description
Technical Field
[0001] This utility model relates to a water level measuring device, specifically an engineering survey water level measuring device, and belongs to the technical field of water level measurement. Background Technology
[0002] During the construction process, it is necessary to measure water structures such as rivers, lakes, and ditches in the early stages of construction, such as shorelines, water levels, and water depths. Only after these preliminary measurements are completed can the subsequent designers plan and construct according to actual needs. Water level measuring devices are required during the measurement process.
[0003] A search revealed Chinese Patent Publication No. CN222013247U, which discloses a water level measuring device for engineering surveys. The device includes a float and a cover. A sinking assembly is installed at the bottom of the float, comprising a counterweight and a retaining sleeve. This patent allows for locking of the pull rope, preventing it from continuing to move downwards due to inertia from other equipment. This ensures the accuracy of water level measurement, maintains the same equipment weight for each measurement, and prevents changes in the device's height above the water surface due to moisture affecting the device's interior. This effectively guarantees the precision of water level measurement and is suitable for use in engineering surveys.
[0004] However, this patent is not suitable for simultaneously measuring different water levels in the same body of water, making it difficult to guarantee the accuracy of water level measurement. Secondly, since the float is floating on the water surface, people are easily affected by the water flow and deviate from the original measurement position, which further makes it difficult to guarantee the accuracy of water level measurement. Therefore, we provide an engineering survey water level measurement device to solve the above problems. Summary of the Invention

Detailed Implementation
[0022] The present invention will now be further described with reference to the accompanying drawings.
[0023] Please see Figures 1-4 The system includes a support plate 1, a connecting component 2 at the upper end of the support plate 1, an extension component 3 for extending the length of the connecting component 2 inside the connecting component 2, a support component 4 for supporting the connecting component 2 at the lower part of the connecting component 2, a U-shaped frame 5 connected to the upper surface of the support plate 1, a power mechanism 6 inside the U-shaped frame 5, a support rod 7 on one side of the power mechanism 6, and water level monitors 8 arranged in a linear array from top to bottom fixedly installed on the outer circumferential surface of the support rod 7. The water level monitors 8 are pressure-type water level gauges that measure the pressure in the water to calculate the water level depth. This is a very mature technology. In addition, depending on the actual needs, it can also measure other data in the water, such as temperature and pH, by connecting other detection devices, including but not limited to measuring only the water level. A ring-shaped counterweight 9 is fixedly installed on the outer bottom surface of the support rod 7. The counterweight 9 is made of metal and has a large weight. It resists the inclined force brought by the water flow through gravity, thereby reducing the tilt of the water level monitor 8.
[0024] The connecting component 2 includes a U-shaped groove 201, which is located at the center of the outer top surface of the support plate 1. A straight plate 202 is provided on the right outer wall of the support plate 1 at the U-shaped groove 201. One end of the straight plate 202 is rotatably mounted on the inner side wall of the U-shaped groove 201 via a coupling shaft. The other end of the straight plate 202 is connected to a straight plate 203 via an extension component 3. The extension component 3 includes a groove 3 located at the center of the right outer wall of the straight plate 202. 01. A square plate 302 is slidably connected to the inner side of the slide groove 301. One end of the square plate 302 extends to the outside of the slide groove 301 and is fixedly connected to the straight plate 203. Limiting holes 1 303 and 2 304 distributed in a linear array are respectively provided on the inner side walls of the two sides of the slide groove 301 and the outer side walls of the two sides of the square plate 302. The straight plate 1 202 and the straight plate 203 are fixed to each other by a positioning rod 2 305 that is slidably inserted.
[0025] The support assembly 4 includes a slot 401, which is located at the center of the outer right side wall of the support plate 1. A locking block 402 is engaged with the inner side of the slot 401. One end of the locking block 402 extends to the outside of the slot 401, and an ear plate 403 is fixedly installed on its outer side wall. An ear plate 404 is fixedly installed on the outer bottom surface of the straight plate 202. The inner sides of the ear plates 403 and 404 are rotatably connected to a support plate 405. A through-hole 406 and a through-hole 407 are provided on the inner sides of the slot 401 and the outer sides of the locking block 402. The inner sides of the through-holes 406 and 407 are secured horizontally to the support plate 1 by a sliding positioning rod 408. The locking block 402 is inserted into the slot 401, allowing the support plate 405 to be secured to the ear plate 405. The internal rotation of plate 1 403 and ear plate 2 404 causes straight plate 1 202 to rotate and become horizontal within the U-shaped groove 201. Then, the positioning rod is passed through the locking hole 1 406 and locking hole 2 407 to fix the locking block 402 in the locking groove 401, and straight plate 1 202 is horizontally fixed on the support plate 1. Then, as needed, square plate 302 is inserted into sliding groove 301 to connect straight plate 2 203 with straight plate 1 202. Next, positioning rod 2 305 is passed through limiting hole 1 303 and limiting hole 2 304 to fix straight plate 1 202 and straight plate 2 203 to each other, thereby extending the length of straight plate 1 202. Similarly, the number of straight plates 2 203 is increased sequentially to facilitate the measurement of water areas of different widths and further improve practicality.
[0026] The power mechanism 6 includes a rotating shaft 606. The inner sidewalls of the two sides of the loop frame 5 are rotatably mounted to the rotating shaft 606. A wire reel 607 is fixedly sleeved on the outer circumferential surface of the rotating shaft 606. A wire rope 608 is wound inside the wire reel 607. One end of the wire rope 608 extends to the outside of the loop frame 5 and is fixedly connected to the support rod 7.
[0027] The two ends of the rotating shaft 606 extend to the front and rear outer walls of the loop frame 5, respectively. One end of the rotating shaft 606 is fixedly connected to the output end of the drive motor 601, which is fixedly installed on the front outer wall of the loop frame 5. Meanwhile, a limiting block 602 is fixedly installed on the outer circumferential surface of the other end of the rotating shaft 606. A through-hole 603 distributed in a circular array is provided on the rear outer wall of the loop frame 5 outside the rotating shaft 606. A through-hole 604 adapted to the through-hole 603 is provided on the outer wall of the limiting block 602. The rotating shaft 606 is limited to the loop frame 5 by a positioning rod 605 that is slidably inserted into the inner sides of the two holes 604 and the one hole 603.
[0028] Limiting rings 11 are fixedly installed on the outer top surfaces of straight plate 1 202 and straight plate 2 203. The outside of the wire rope 608 passes through and slides on the inside of the two limiting rings 11. A base plate 10 is fixedly installed on the outer bottom surface of the support plate 1.
[0029] The drive motor 601 is controlled and started to drive the rotating shaft 606 to rotate the wire reel 607 inside the loop frame 5, thereby unwinding the wire rope 608 and placing the support rod 7 into the water area to be measured, allowing the water flow to come into contact with the water level monitor 8. By setting multiple water level monitors 8, the water level at different depths in the same water area can be measured simultaneously, thereby improving the accuracy of water level measurement. Furthermore, the interaction between the annular counterweight 9 and the support rod 7 ensures that the water level monitor 8 is always in a vertical state, reducing the possibility of the water level monitor 8 deviating from its original measurement position due to the influence of water flow, which would cause inaccurate measurement data. At the same time, after the water level monitor 8 reaches the measurement position, the positioning rod 605 is inserted into the inner side of the circular hole 604 and the circular hole 603 to fix the rotating shaft 606 and prevent it from spinning, which would affect the subsequent measurement results.
[0030] The drive motor 601 in this application is a common electrical device in the prior art. This application will not elaborate on its model or internal structure. It can also be replaced by other power sources.
[0031] When using this utility model: first, insert the card block 402 into the card slot 401, and then insert the positioning rod 408 into the card hole 406 and the card hole 407, so that the support plate 405 can horizontally support and fix the straight plate 202 on the support plate 1.
[0032] Meanwhile, according to the width of different water areas, the square plate 302 on the straight plate 203 is inserted into the groove 301 of the straight plate 202, and the positioning rod 305 is inserted into the limiting hole 303 and the limiting hole 304, thereby extending the length of the straight plate 202.
[0033] Finally, the support plate 1 is fixed on the bank of the measured water area. The drive motor 601 is started to drive the rotating shaft 606 to drive the wire reel 607 to rotate inside the loop frame 5, so as to unwind the wire rope 608, thereby driving the support rod 7 and multiple water level monitors 8 to be placed in the measured water area, so that the water flow comes into contact with the multiple water level monitors 8. The water level at different depths in the same water area can be measured simultaneously by the multiple water level monitors 8, thereby improving the accuracy of water level measurement.
[0034] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
