Description

Technical Field

[0001] The present application relates to the technical field of water conservancy engineering, and in particular to a water level early warning device. Background Art

[0002] With the rapid advancement of society, the wave of urbanization construction is intensifying, and people's requirements for the safety and stability of various infrastructures are also rising. Among them, the water level warning device, with its unique status, is an important tool for safety monitoring, and its application field and importance are becoming increasingly prominent. Whether in water conservancy facilities such as reservoirs and dams, or in underground spaces such as urban drainage systems, underground garages, and tunnels, water level warning devices play an indispensable role. The catastrophic consequences of excessive water levels, such as dam breaches and dike breaches, the waterlogging caused by excessive water accumulation, and the potential safety hazards caused by the rise of water levels in underground spaces, all make real-time monitoring and early warning of water levels an important part of ensuring public safety.

[0003] However, although the water level warning devices currently on the market have achieved certain results, there is still room for improvement. For example, existing water level warning devices, such as a water level warning device with publication number CN218765507U, can adjust the height of the floating plate according to actual conditions through the cooperation of components such as a screw rod, a movable seat, a test tube, and a movable rod, thereby realizing monitoring and early warning of different water levels. However, the inventors found in actual applications that when the device is faced with interference from external factors (such as wind, rain, waves or floating objects), the floating plate is prone to unnecessary up and down floating with the water flow, which may cause the warning device to misreport, thereby producing a "wolf cry" effect, causing local residents to become numb to the alarm signal. In addition, when parts of the device are damaged, the maintenance process is relatively complicated and not convenient enough. Utility Model Content

DETAILED DESCRIPTION

[0025] The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments.

[0026] Example:

[0027] See also Figure 1 , Figure 2 A water level warning device includes an alarm 1, which is equipped with a waterproof shell to ensure the stable operation of the device in a humid environment. At the same time, the built-in battery provides a continuous and stable power supply for the alarm 1. Its fixed end is flange-connected to the top of the flange pipe 211 to ensure the stability and sealing of the structure. The output end of the alarm extends into the flange pipe 211, which can accurately detect water level changes and quickly issue an early warning when the preset threshold is reached, so that corresponding countermeasures can be taken in time.

[0028] See also Figure 1 , Figure 2 , Figure 3 , Figure 4 A water level warning device includes a water level detection mechanism 2 connected to the bottom flange of an alarm 1, the water level detection mechanism 2 is composed of a measuring mechanism 21, a display mechanism 22, a water inlet mechanism 23, a protective mechanism 24 and a locking mechanism 25, wherein the measuring mechanism 21 includes a flange pipe 211, a float 212, a conductive sheet 213 and an exhaust hole 214; the display mechanism 22 includes a transparent plate 221 and a scale 222; the water inlet mechanism 23 includes a water tank 231, a plurality of water inlet channels 232 and a connecting tube 233; the protective mechanism 24 includes a bottom ring 241, a plurality of support columns 242 and a top ring 243; the locking mechanism 25 includes two groups of blocks 251 and two groups of slots 252.

[0029] Among them, the measuring mechanism 21 plays a vital role as the core component of the water level warning device. It includes key components such as flange pipe 211, float 212, conductive sheet 213 and exhaust hole 214. The flange pipe 211 is a connecting component, and its two ends are respectively connected to the alarm 1 and the water inlet mechanism 23 through flanges, ensuring the stability and sealing of the device. It is convenient for users to replace the flange pipe 211 and is suitable for waters of different depths. At the same time, the side wall of the flange pipe 211 is provided with an exhaust hole 214, which is used to discharge the air inside the pipe due to the rising water level to ensure the accuracy of water level measurement. The float 212 and the conductive sheet 213 are installed inside the flange pipe 211, forming the key part of water level detection. The float 212 has buoyancy and can rise with the rise of the water level. The conductive sheet 213 is located above the float 212. When the water level rises and pushes the float 212 up, the top of the float 212 will fit with the bottom of the conductive sheet 213. This fitting action will trigger the contact between the conductive sheet 213 and the alarm 1. A pressure trigger switch is provided on the alarm 1 at a position corresponding to the contact with the conductive sheet 213. The conductive sheet 213 contacts the pressure trigger switch, connecting the working circuit of the alarm 1, and then causing the alarm 1 to sound an alarm. This design is simple and effective, and can monitor water level changes in real time and accurately, and issue an early warning when necessary. The float 212 of this design is also not affected by external wind and waves.

[0030] Among them, the design of the display mechanism 22 fully reflects the perfect combination of practicality and intuitiveness. It is mainly composed of a transparent plate 221 and a scale 222, providing users with a convenient way to observe the water level. As the core component of the display mechanism 22, the transparent plate 221 is embedded in the installation port opened on the side wall of the flange pipe 211 and filled with waterproof glue. This design makes the transparent plate 221 and the flange pipe 211 form a whole, which not only ensures the stability of the structure, but also ensures the accuracy of observing the water level. The transparent plate 221 is made of high-transparency material, so that the user can clearly see the water level inside the flange pipe 211. The scale 222 is opened on the outer wall of the transparent plate 221, providing users with an intuitive reference for the water level. The scale 222 adopts an easily recognizable marking method, so that users can quickly and accurately read the current water level height. By comparing the mark on the scale 222 with the actual water level, the user can easily grasp the water level change, so as to take corresponding countermeasures in time.

[0031] Among them, the design of the water inlet mechanism 23 is convenient for water to evenly enter the inside of the flange pipe 211. The water tank 231 is the main part of the water inlet mechanism 23, and its side wall is evenly spaced to open a number of water inlet channels 232. These water inlet channels 232 are designed to be both reasonable and practical, and they can ensure that water can smoothly enter the inside of the water tank 231 at different water levels. At the same time, the equidistant arrangement of the water inlet channels 232 also helps to maintain the uniformity of the water flow, further improving the accuracy of water level detection. The connecting tube 233 is a key component connecting the water tank 231 and the flange pipe 211. Its bottom end is welded with the top of the water tank 231 to ensure a stable connection between the two. At the same time, the top of the connecting tube 233 is connected to the bottom of the flange pipe 211 through a flange. This connection method is convenient for disassembly and maintenance, and can ensure the sealing of the connection to prevent water from leaking from the connection.

[0032] The connection between the top of the water tank 231 and the bottom of the connecting tube 233 adopts seamless welding technology. This welding method ensures that the connection between the two is smooth and seamless, thereby effectively preventing water from leaking from the connection, further enhancing the sealing and stability of the device. This makes the entire device more beautiful and improves the overall texture of the device. This design not only improves the practicality of the water level warning device, but also reflects the pursuit of excellence in process details.

[0033] Among them, the protection mechanism 24 provides all-round protection for the water tank 231. The bottom ring 241 serves as the basis of the protection mechanism 24, and a number of support columns 242 are welded on its surface at equal intervals. These support columns 242 firmly support the top ring 243, and threaded holes are provided on the top of the top ring 243. The top ring 243 fits tightly with the top of the support column 242 to form a complete protection frame. In order to further enhance the stability of the protection mechanism 24, the designer uses hexagonal bolts 244 for fixing. The bottom ends of these bolts penetrate the top ring 243 and are threadedly connected with the support column 242, thereby ensuring the tight connection between the top ring 243 and the support column 242. This connection method is not only simple and effective, but also convenient for disassembly and maintenance. In addition, the inner walls of the bottom ring 241 and the top ring 243 are also welded with a locking mechanism 25, which is clamped and connected with the outer wall of the water tank 231. This design not only ensures the stable position of the water tank 231 in the protection mechanism 24, but also prevents external factors from interfering with and damaging the water tank 231. Finally, the setting of the blocking net 245 adds a layer of safety protection to the protection mechanism 24. It can effectively prevent floating objects and impurities in the water from entering the device, thereby protecting the normal operation of the measuring mechanism 21 and other key components. And the bottom of the protection mechanism 24 is provided with a mounting hole for easy installation at a predetermined position.

[0034] Among them, the locking mechanism 25 is composed of two groups of blocks 251 and two groups of slots 252, which together realize the stable connection between the water tank 231 and the protective mechanism 24. Two groups of slots 252 are respectively opened at both ends of the water tank 231, and the shape and size of these slots 252 match the blocks 251. The outer ends of the two groups of blocks 251 are respectively welded to the inner rings of the bottom ring 241 and the top ring 243 to form a whole. During installation, the inner end of the block 251 only needs to be aligned with the slot 252 and snapped in, so as to realize the stable connection between the water tank 231 and the protective mechanism 24. This snap-in method is not only simple and easy, but also has high stability. Once the block 251 and the slot 252 are snapped into place, they will form a close fit and are not easy to loosen or fall off. This design not only facilitates the assembly and disassembly of the device, but also ensures the stability and reliability of the device during operation.

[0035] The working principle of the water level warning device is as follows: when in use, the device is installed at a designated location. When the water level rises, water will enter the water tank 231 through the barrier net 245 and the support columns 242 and the water inlet channel 232. At the same time, the water level continues to rise and enters the flange pipe 211 through the connecting tube 233, thereby pushing the float 212 up. The rise of the float 212 will push the conductive sheet 213 up, triggering the contact between the conductive sheet 213 and the alarm 1, thereby triggering the pressure trigger switch of the alarm 1, causing the alarm 1 to sound an alarm. At the same time, the user can intuitively understand the current water level by observing the scale 222 on the transparent plate 221.

[0036] It should be noted that the specific models and specifications of the alarm 1, float 212, transparent plate 221, and barrier net 245 need to be selected and determined based on the actual specifications of the device, and the specific selection calculation method adopts the existing technology in this field, so it will not be described in detail.

[0037] The power supply and principle of the alarm 1 are clear to those skilled in the art and will not be described in detail here.

[0038] It is obvious to those skilled in the art that the present application is not limited to the details of the exemplary embodiments described above, and that the present application can be implemented in other specific forms without departing from the spirit or essential features of the present application. Therefore, the embodiments should be regarded as exemplary and non-limiting in all respects, and the scope of the present application is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims be included in the present application. Any reference numeral in a claim should not be regarded as limiting the claim to which it relates.
