Technical Field

[0001] This utility model belongs to the technical field of water level monitoring devices, and in particular relates to a float-type pressure measuring tube water level monitoring device. Background Technology

[0002] Currently, water level observation using piezometers mainly employs electrical water level gauges, requiring manual periodic lowering of the probe to acquire data.

[0003] When using an electrical water level gauge to take readings on-site, it is necessary to carry specialized instruments, which is not only inconvenient to measure but also costly. Utility Model Content

[0004] The purpose of this invention is to provide a float-type pressure gauge water level monitoring device to solve the problems mentioned in the background art.

[0005] In view of this, the present invention provides a float-type piezometer water level monitoring device, comprising:

[0006] The pressure measuring tube has through holes at the bottom and around the sides. The pressure measuring tube is buried in the dam body, and water in the dam body can enter the pressure measuring tube through the through holes.

[0007] A telescopic ruler that can extend or retract under force to achieve different length ranges;

[0008] A float, with the lower end of the retractable scale inserted into the float;

[0009] A ruler fixing sleeve is provided, wherein the upper end of the retractable ruler is inserted and fixed to the bottom surface of the ruler fixing sleeve, and the retractable ruler and the float are placed together in the pressure measuring tube and fixed to the top of the pressure measuring tube by the ruler fixing sleeve.

[0010] The water in the pressure measuring tube raises the float, allowing the retractable scale to extend and retract, thus revealing the real-time length of the scale fixing sleeve. The water level in the pressure measuring tube can be obtained by subtracting the real-time scale length from the elevation of the pipe opening.

[0011] In a further embodiment of this utility model, an insert block is integrally formed on the bottom surface of the scale fixing sleeve, and the upper end of the retractable scale is adapted to be inserted and fixed with the insert block, so that the retractable scale and the scale fixing sleeve are perpendicular to each other.

[0012] In a further embodiment of this utility model, a positioning ring is formed on the bottom surface of the scale fixing sleeve, and a fixing groove is formed between the positioning ring and the inner wall of the scale fixing sleeve. When the scale fixing sleeve is disposed on the upper end of the pressure measuring tube, the upper end of the pressure measuring tube is inserted into the fixing groove and locked in place.

[0013] In a further embodiment of this invention, the overall length formed by the retractable scale and the float is less than the height of the pressure measuring tube.

[0014] In a further embodiment of this utility model, a top cover is also included, wherein the top cover is threadedly connected to the scale fixing sleeve, and the top cover can be adapted to cover the top of the scale fixing sleeve.

[0015] In a further embodiment of this invention, the pressure measuring tube is a galvanized steel pipe or a rigid plastic pipe.

[0016] The beneficial effects of this utility model are:

[0017] This device is buried inside the dam. Water enters the piezometer through the through-hole, and the water level raises the float. Under the action of the float, the extendable scale adjusts and positions itself at the real-time scale length. The piezometer is made of galvanized steel or hard plastic. The real-time scale length is read directly. The real-time water level in the piezometer is obtained by subtracting the real-time scale length from the elevation of the piezometer opening. This allows for the determination of whether the dam's seepage pressure is within the allowable range. This device simplifies the observation process, is easy to use, eliminates the need to bring specialized instruments to the site, and has low device and maintenance costs.

Additionally, features described with reference to certain examples may be combined in other examples.

[0026] This embodiment provides a float-type piezometer water level monitoring device, which is mainly composed of a piezometer tube 1, a retractable scale 2, a float 3, a scale fixing sleeve 4, and a top cover 5. It can achieve accurate and real-time monitoring of water level, and is especially suitable for water level observation work related to seepage pressure in engineering scenarios such as dams.

[0027] The piezometer 1 has a regular cylindrical shape, with through holes 10 at its bottom and around its sides. The piezometer 1 is completely embedded in the dam body, allowing water to enter through the through holes 10, ensuring smooth water entry and the formation of a stable water level within the pipe. In practical applications, water can enter the pipe cavity through the through holes 10, while the pipe body serves to contain the water, create a stable monitoring environment, and provide a mounting platform for subsequent components.

[0028] In this embodiment, the retractable scale 2 is a key component for water level measurement. It features the ability to freely extend and retract under pressure, allowing for different length ranges to accommodate monitoring water levels at varying depths. The scale surface is engraved with precise graduations, increasing sequentially from bottom to top to accurately reflect its extension / retraction length. During assembly, the lower end of the retractable scale 2 is connected to the float 3, while the upper end is fixed to the scale fixing sleeve 4. When the float 3 changes position due to buoyancy, it synchronously extends and retracts the retractable scale 2. The retractable scale 2 is an existing product, not detailed in this embodiment, and is specifically named "A Retractable Scale." Based on this structure, distance sensors are installed at the top and bottom of the retractable scale 2. The distance is calculated in real-time by these two sensors, representing the real-time length of the retractable scale 2, and the result is displayed on an external counter.

[0029] The float 3, as the core component for sensing buoyancy, is made of lightweight material and has a spherical structure, providing excellent buoyancy performance. It can easily float on the water surface and maintain a stable posture during floating, without easily tilting or overturning. To achieve a secure connection with the retractable scale 2, the top of the float 3 has a suitable mounting structure. The lower end of the retractable scale 2 can be tightly inserted into the mounting structure inside the float 3. The connection forms a stable whole, ensuring that the float 3 can reliably drive the retractable scale 2 to move synchronously as the water level changes. The lower end of the retractable scale 2 and the bottom of the float 3 are on the same horizontal plane. The height of the water level inside the piezometer 1 is obtained by subtracting the actual length of the scale from the elevation of the piezometer 1's inlet, thus determining whether the dam's seepage pressure is within the allowable range. The inlet elevation is the height of the piezometer 1, which can be detected instantly by a height sensor; this will not be elaborated further in this embodiment.

[0030] In this embodiment, the scale fixing sleeve 4 mainly serves to fix the upper position of the retractable scale 2 and connect and fix the entire device to the top of the pressure measuring tube 1. Its overall structure is ring-shaped, and its design is compatible with the top of the pressure measuring tube 1 and the upper end of the retractable scale 2. Regarding the fit with the retractable scale 2, an insert 40 is integrally formed on the bottom surface of the scale fixing sleeve 4. The shape and size of the insert 40 perfectly match the interface at the upper end of the retractable scale 2, allowing the upper end of the retractable scale 2 to be tightly fitted and fixed to the insert 40. This connection method ensures that the retractable scale 2 and the scale fixing sleeve 4 remain perpendicular to each other, preventing the scale from tilting and ensuring the accuracy of scale readings. Regarding the fixed fit with the pressure measuring tube 1, a positioning ring 41 is also formed on the bottom surface of the scale fixing sleeve 4. A ring-shaped fixing groove 42 is formed between the positioning ring 41 and the inner wall of the scale fixing sleeve 4. When the scale fixing sleeve 4 is placed on the upper end of the pressure measuring tube 1, the upper end of the pressure measuring tube 1 can be inserted into the fixing groove 42. Through the tight engagement between the fixing groove 42 and the upper end of the pressure measuring tube 1, a stable connection between the scale fixing sleeve 4 and the pressure measuring tube 1 is achieved. This allows the retractable scale 2 and the float 3 to be stably placed together in the pressure measuring tube 1, ensuring the structural stability of the entire device during operation.

[0031] During device assembly, firstly, insert the lower end of the retractable scale 2 into the mounting structure at the top of the float 3, ensuring a secure connection. Next, fit and insert the upper end of the retractable scale 2 into the insert block 40 on the bottom surface of the scale fixing sleeve 4, ensuring the retractable scale 2 and the scale fixing sleeve 4 are perpendicular. Then, place the assembled retractable scale 2 and float 3 together into the pressure measuring tube 1, aligning the fixing groove 42 on the bottom surface of the scale fixing sleeve 4 with the upper end of the pressure measuring tube 1, inserting the upper end of the pressure measuring tube 1 into the fixing groove 42 for snap-fit ​​fixation, thus completing the main assembly of the device. Finally, install the top cover 5 to the scale fixing sleeve 4 via a threaded connection. The top cover 5 fits and covers the top of the scale fixing sleeve 4, serving to prevent dust and water damage and protect the upper structure of the retractable scale 2, preventing external impurities from entering the device and affecting the normal operation of the components.

[0032] After the device is installed, the pressure measuring pipe 1 is vertically buried inside the dam body. Water enters the pipe cavity through the through-hole of the pressure measuring pipe 1. As water continuously enters, the water level inside the pressure measuring pipe 1 gradually rises. When the water level contacts the float 3, it generates an upward buoyancy force on the float 3. As the water level continues to rise, the buoyancy gradually increases until it exceeds the total weight of the float 3 and the telescopic ruler 2. The float 3 then moves upward with the rising water level. During the upward movement of the float 3, it causes the telescopic ruler 2 connected to it to extend upward synchronously, changing the length of the telescopic ruler 2. The operator can directly read the actual length of the telescopic ruler 2 from an external counter.

[0033] When calculating the water level, the difference between the elevation of the piezometer 1 opening and the actual length of the extendable scale 2 is the real-time water level inside the piezometer 1. Based on this calculated real-time water level, staff can further determine whether the seepage pressure in engineering projects such as dams is within acceptable limits, thus promptly assessing the safety status of the project.

[0034] To ensure the device functions correctly under varying water levels, its structural design has been optimized. Specifically, the overall length of the telescopic scale 2 and float 3 is less than the height of the pressure measuring tube 1. This design avoids situations where the float 3 touches the bottom of the pressure measuring tube 1 or the telescopic scale 2 cannot extend or retract properly at low water levels due to an excessively long overall length of the telescopic scale 2 and float 3. This ensures that even at the lowest water level, the float 3 can move freely with water level changes, and the telescopic scale 2 can be adjusted normally, effectively expanding the monitoring range and improving the device's applicability.

[0035] Simplifying the observation process and enabling real-time monitoring: The device uses the synergistic effect of the float 3 and the retractable scale 2 to directly convert water level changes into scale length changes. Staff only need to read the scale from the outside and perform simple calculations to obtain the real-time water level height. No complicated operation steps are required, which greatly simplifies the observation process and enables real-time monitoring of water levels, allowing for timely understanding of dynamic changes in water levels.

[0036] Easy to install and maintain, low cost: The components of the device have simple structures, and the assembly process does not require complex technical means. Staff can complete the installation operation after simple training. In daily maintenance, since the device does not use precision electronic technology, the components are not prone to failure. Maintenance only requires inspection and cleaning of the connection points, making maintenance difficult. At the same time, the device is made of conventional materials, eliminating the need for expensive precision components, which greatly reduces the manufacturing cost and subsequent maintenance cost, making it suitable for large-scale promotion and application.

[0037] Less affected by the environment and highly stable: The core working components of the device are all located inside the pressure measuring tube 1. The pressure measuring tube 1 can provide good protection for the internal components and avoid the influence of external environmental factors (such as wind, rain, dust accumulation, etc.) on the working status of the components. At the same time, the cooperation structure between the float 3 and the retractable scale 2 is stable and not easily affected by factors such as water fluctuations. It can maintain stable monitoring performance under different environmental conditions and ensure the accuracy and reliability of monitoring data.

[0038] The embodiments of this application have been described above with reference to the accompanying drawings. Unless otherwise specified, the embodiments and features in the embodiments of this application can be combined with each other. This application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
