Abstract
Description
Technical Field
[0001] This invention relates to the field of hydrological technology, specifically a hydrological and water resources water level early warning device. Background Technology
[0002] Hydrology and water resources refer to the research and monitoring of water resources. In the process of water resource monitoring, the water level of rivers or lakes is typically monitored over a long period. Sensors are usually installed to monitor the water level to prevent rapid rises in water levels during rainy days or floods, which could lead to flooding and disrupt the lives of nearby residents if staff are unable to detect the situation in time.
[0003] The existing water level warning devices are usually fixed in height, which makes them less adaptable and unable to be adjusted appropriately for different lakes or rivers with different warning heights. Alternatively, the height can be adjusted by rotating a gear to drive a rack and pinion to rise and fall, which is cumbersome, inconvenient and slow. Summary of the Invention
[0004] The purpose of this invention is to provide a hydrological and water resource water level early warning device to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, the present invention provides the following technical solution:

Detailed Implementation
[0030] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention. The present invention will be described in detail below with reference to the accompanying drawings and embodiments.
[0031] In one embodiment, see [reference] Figures 1-10 A hydrological and water resources water level early warning device includes a load-bearing plate 1, a mounting plate 2, an external threaded sleeve 5, an internal threaded sleeve 10, and a counting component. The external threaded sleeve 5 has a first threaded connecting seat 7 at its top and a first threaded connecting sleeve 6 at its bottom. Multiple sets of external threaded sleeves 5 are connected end-to-end via the threaded connection of the first threaded connecting seat 7 and the first threaded connecting sleeve 6. The internal threaded sleeve 10 has a second threaded connecting seat 12 at its top and a second threaded connecting sleeve 11 at its bottom. Multiple sets of internal threaded sleeves 10 are connected end-to-end via the threaded connection of the second threaded connecting seat 12 and the second threaded connecting sleeve 11. The internal threaded sleeve 10 is slidably connected inside the external threaded sleeve 5. A float 3 is fixedly connected to the edge of the mounting plate 2. A sealing threaded seat 4 is fixedly connected to the top of the load-bearing plate 1, and the sealing threaded seat 4 is connected to the first threaded connecting sleeve at the bottom of the lowest external threaded sleeve 5. 6. The mounting plate 2 is connected by mutual threads. A sealing threaded cylinder 13 is fixedly connected to the bottom of the mounting plate 2. The sealing threaded cylinder 13 is threadedly connected to the second threaded connecting seat 12 at the top of the inner threaded sleeve 10. A connecting bolt 14 is fixedly connected inside the sealing threaded seat 4. A connecting nut 15 is threadedly connected to the connecting bolt 14. A lifting ring 16 is fixedly connected to the connecting nut 15. A connecting hole 20 is provided inside the mounting plate 2. A first fixing frame 17 is fixedly connected to the mounting plate 2. A winding drum 18 is rotatably connected inside the first fixing frame 17. A coil spring 22 is connected between the winding drum 18 and the first fixing frame 17. One end of a connecting rope 21 is wound and connected to the first winding drum 18. The other end of the connecting rope 21 passes through the connecting hole 20 and is connected to the lifting ring 16. A counting component is installed on the mounting shaft of the winding drum 18. The safety number on the counting component is green, and the numbers above the safety number are red. It is used to count the rotation of the winding drum 18.
[0032] This invention first selects a certain number of external threaded sleeves 5 and internal threaded sleeves 10 based on the predicted water depth. Simultaneously, multiple sets of external threaded sleeves 5 and internal threaded sleeves 10 are connected end-to-end through the threaded connection between the first threaded connecting seat 7 and the first threaded connecting sleeve 6, and the threaded connection between the second threaded connecting seat 12 and the second threaded connecting sleeve 11. The external threaded sleeves 5 are then fixedly connected to the load-bearing plate 1 via a sealing threaded seat 4, while the internal threaded sleeves 10 are fixedly connected to the mounting plate 2 via a sealing threaded connecting sleeve. Then, one end of the connecting rope 21 is relatively fixed to the load-bearing plate 1 through the threaded connection between the connecting nut 15 and the connecting bolt 14. Simultaneously, the sliding connection between the external threaded sleeves 5 and the internal threaded sleeves 10 enables mutual floating between the load-bearing plate 1 and the mounting plate 2. At this time, the mounting plate 2 floats under the action of the float 3. On the water surface, during the installation process, as the connecting nut 15 is threaded onto the connecting bolt 14, the connecting nut 15 pulls the connecting rope 21 out through the lifting ring 16. The connecting rope 21 drives the winding drum 18 to rotate, and the coil spring 22 stores energy. At the same time, the counting component counts the number of rotations of the winding drum 18 and measures the length of the connecting rope 21 released by the winding drum 18 based on the number of rotations. This, in turn, measures the relative height between the mounting plate 2 and the load-bearing plate 1. When the water level drops, the coil spring 22 drives the winding drum 18 to reset, thereby driving the winding drum 18 to rotate and rewind the connecting rope 21. This achieves real-time monitoring of the water level. At this time, the water level can be monitored by observing the numbers and colors of the numbers on the counting component.
[0033] In one instance of this embodiment, please refer to Figures 1-10 The load-bearing plate 1 is fixedly connected to the bottom center with a plug rod 8 and a positioning rod 9 is fixedly connected to the edge of the load-bearing plate 1. The present invention installs and fixes the load-bearing plate 1 by inserting the plug rod 8 into the bottom of the water, and positions and supports the load-bearing plate 1 by setting the positioning rod 9, thereby preventing the load-bearing plate 1 from flipping over at the bottom of the water.
[0034] In one instance of this embodiment, please refer to Figures 1-10 A guide wheel 19 is fixedly connected to the mounting plate 2 between the winding drum 18 and the connecting hole 20. The guide wheel 19 and the connecting rope 21 are in rolling contact with each other. The present invention uses the guide wheel 19 to make rolling contact between the connecting rope 21 and the mounting plate 2, thereby preventing the connecting rope 21 from being damaged by friction.
[0035] In one instance of this embodiment, please refer to Figures 1-10The counting component includes a second fixed frame 24 fixedly connected to the mounting plate 2, a counter 25 rotatably connected inside the second fixed frame 24, a scale line 28 fixedly connected to the second fixed frame 24, the scale line 28 and the counter 25 cooperating with each other, a first synchronous pulley 23 fixedly connected to the mounting shaft of the winding drum 18, a second synchronous pulley 26 fixedly connected to the drive shaft of the counter 25, and a synchronous belt 27 connecting the first synchronous pulley 23 and the second synchronous pulley 26.
[0036] The counting component drives the winding drum 18 to rotate through the release of the connecting rope 21 and the reset of the coil spring 22. The winding drum 18 drives the first synchronous wheel 23 to rotate, and the first synchronous wheel 23 drives the second synchronous wheel 26 to rotate synchronously. The second synchronous wheel 26 drives the counter 25 to rotate, thereby driving the counter 25 to rotate and count. The counter 25 then converts the number of rotations of the winding drum 18 into the relative height between the mounting plate 2 and the load-bearing plate 1, that is, the relative height of the water surface. At the same time, the scale line 28 facilitates the intuitive observation of the scale of the counter 25.
[0037] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
