Description

Technical Field

[0001] This utility model relates to the field of water level monitoring technology, specifically to a water level monitoring and early warning device for water conservancy projects. Background Technology

[0002] Water level monitoring and early warning devices in water conservancy projects are integrated systems composed of sensors, data transmission, data processing, and early warning systems. They are used to monitor water level changes in real time and issue timely alarms. The basic part uses a mechanical structure to assist the water detection part in moving in the water flow to accurately calculate water level changes.

[0003] Most existing water level monitoring and early warning devices are customized. Typically, different styles are customized according to the different environments of the monitoring points. This results in long delivery cycles, difficulty in debugging due to environmental differences at different monitoring points, and high subsequent maintenance costs. Utility Model Content

[0004] To solve the above-mentioned technical problems, this utility model proposes a water level monitoring and early warning device for water conservancy projects.

[0005] The technical solution of this utility model is implemented as follows: a water level monitoring and early warning device for water conservancy projects, comprising:

[0006] Mounting base, used to fix the overall structure;

[0007] The multi-level monitoring section is installed throughout the mounting base, and the multi-level monitoring section has a fixed displacement spacing in the height direction;

[0008] A feedback base station is provided with a limiting part that communicates with the mounting base, and the limiting part supplies air pressure into the mounting base;

[0009] The float level gauge has two sliding channels and two sliding positions on the mounting base.

[0010] In use, due to the differences in water level monitoring environments in water conservancy projects, existing water level monitoring devices are adapted to different types of monitoring point environments. This solution is designed to be usable in various environments depending on the monitoring environment. In this state, it can be used in situations with low flow, shallow water level, and complex water environment. Through two sliding rods and the main rod, it can resist greater impacts, such as aquatic organisms, tree branches and debris mixed in the water, which improves the overall pressure resistance and increases the service life.

[0011] In the second state, when monitoring deeper water levels, the restriction between the first sensing slide and the limiting part is released. When the float level gauge moves on the first sensing slide, the float level gauge can then detect water levels at deeper depths.

[0012] The specific detection method involves calculating the distance between the data acquisition sensor and the riverbed under two different working conditions. Based on the position of the float level gauge in both conditions, the height of the float and the distance between the float and the data acquisition sensor are calculated, and then the water level is determined.

[0013] Furthermore, the top of the mounting base is provided with a fixing part, which is detachably connected to the bottom of the feedback base station and is fixedly connected to the top of the mounting base.

[0014] When the whole unit is installed in the preset position, it can be transported separately, making it more convenient to operate.

[0015] Furthermore, the feedback base station includes a base station body, and an external threaded pipe is provided at the bottom of the base station body, the external threaded pipe being threadedly connected to the fixed part.

[0016] This ensures unobstructed air passages, facilitating internal filling pressure. A pressure detector can also be installed to monitor the internal pressure; if it falls below a threshold, air is pumped in, and if it rises above the threshold, the air pump stops pumping.

[0017] Furthermore, the multi-level monitoring section includes a fixed section and a movable section. The fixed section includes a main rod and two limiting sections disposed at the upper and lower ends of the main rod.

[0018] The air pump can increase the pressure inside the limiting part and expand the air cushion from the elliptical opening. The expanded air cushion can then contact the protruding part on the first sensing slide, thereby fixing the first sensing slide. Moreover, it can switch between the two modes quickly, and the air pump can also be controlled by the built-in controller to complete the switching.

[0019] Furthermore, the active part includes a first sensing slide and a second sensing ring, the first sensing slide and the second sensing ring having the same structure.

[0020] Furthermore, the first sensing slide has a protruding portion inside, and mounting ports are provided on both the front and rear sides of the first sensing slide.

[0021] Furthermore, the movable part includes two slide rods, the two ends of which are fixedly connected to the mounting ports on the first sensing slide and the second sensing ring, respectively.

[0022] Furthermore, the float level gauge is provided with vertical holes that match the main rod and slide on the two slide rods.

[0023] Furthermore, the limiting portion includes a concave ring, and the concave ring is provided with a plurality of elliptical openings, and an air cushion is provided inside the elliptical openings.

[0024] This utility model has the following beneficial effects:

[0025] 1. This solution is designed to be used in various environments depending on the monitoring conditions, such as when the flow rate is low, the water level is shallow, and the water environment is complex. The two sliding rods and the main rod can withstand greater impacts, such as aquatic organisms, tree branches and debris mixed in the water, which improves the overall pressure resistance and increases the service life.

[0026] 2. When monitoring water levels at greater depths, the restriction between the first sensing slide and the limiting part is removed. When the float level gauge moves on the first sensing slide, the float level gauge can then detect water levels at greater depths.

[0027] 3. The air pump can increase the pressure inside the limiting part and expand the air cushion from the elliptical opening. The expanded air cushion can then contact the protruding part at the position of the first sensing slide 7, thereby achieving the purpose of fixing the first sensing slide. Moreover, it can switch between the two situations quickly, and the air pump can also be controlled by the built-in controller to complete the switching. Attached Figure Description

[0034] The technical solutions in the embodiments of this utility model will be clearly and completely described below. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0035] Reference Figures 1 to 4 The water level monitoring and early warning device for a water conservancy project shown includes:

[0036] Mounting base 2 is used to fix the overall structure;

[0037] The multi-level monitoring section is installed through the mounting base 2, and the multi-level monitoring section has a fixed displacement spacing in the height direction;

[0038] The feedback base station includes a data acquisition sensor 4 and a signal transmission unit that feeds the data back to the water station, a sensing unit that detects the height difference between the first sensing slide 7 and the second sensing ring 8, and a calculation module for calculating the position of the float water level gauge 10. The feedback base station is provided with a limiting part 6 that communicates with the mounting base 2, and the limiting part 6 delivers air pressure into the mounting base 2.

[0039] The float level gauge 10 has two sliding channels and two sliding positions on the mounting base 2.

[0040] In practice, due to the varying environments for water level monitoring in water conservancy projects, existing systems require different types of water level monitoring devices adapted to different monitoring point environments. This solution is designed to be usable in various environments, such as... Figure 2 As shown in the figure, the sliding rod 9 is not shown. In this state, it can be used in situations with low flow, shallow water, and complex water environment. The two sliding rods 9 and the main rod 1 can resist greater impacts, such as aquatic organisms, tree branches and debris mixed in the water, which improves the overall pressure resistance and increases the service life.

[0041] In the second state, such as Figure 1 As shown, when monitoring deeper water levels, the restriction between the first sensing slide 7 and the limiting part 6 is lifted. When the float level gauge 10 moves on the first sensing slide 7, the float level gauge 10 can then detect the water level at deeper depths.

[0042] The specific detection method involves calculating the distance between the data acquisition sensor 4 and the riverbed under two working conditions. Based on the position of the float level gauge 10 in the two conditions, the height of the float and the distance between the float and the data acquisition sensor 4 are calculated, and then the water level is calculated.

[0043] The top of the mounting base 2 is provided with a fixing part 3, which is detachably connected to the bottom of the feedback base station and is fixedly connected to the top of the mounting base 2.

[0044] When the whole unit is installed in the preset position, it can be transported separately, making it more convenient to operate.

[0045] The feedback base station includes a base station body, and an external threaded pipe is provided at the bottom of the base station body. The external threaded pipe is threadedly connected to the fixed part 3.

[0046] This ensures unobstructed air passages, facilitating internal filling pressure. A pressure detector can also be installed to monitor the internal pressure. If the pressure is below a threshold, air is pumped into the interior; if it is above the threshold, the air pump 5 stops pumping.

[0047] The multi-level monitoring section includes a fixed section and a movable section. The fixed section includes a main rod 1 and two limiting sections 6 set at the upper and lower ends of the main rod 1. The limiting section 6 includes an inner concave ring 61, and multiple elliptical openings 62 are provided at the inner concave ring 61. An air cushion 63 is provided inside the elliptical openings 62.

[0048] In this embodiment, the air pump 5 can increase the pressure inside the limiting part 6 and expand the air cushion 63 from the elliptical opening 62. The expanded air cushion 63 can then contact the protruding part 72 at the position of the first sensing slide 7, thereby achieving the purpose of fixing the first sensing slide 7. Moreover, the switching between the two situations can be done quickly, and the air pump 5 can also be controlled by the built-in controller to complete the switching.

[0049] The movable part includes a first sensing slide 7 and a second sensing ring 8, which have the same structure. The first sensing slide 7 has a protrusion 72 inside, and mounting ports 71 are provided on both the front and rear sides of the first sensing slide 7.

[0050] The distance between the first sensing slider 7 and the second sensing ring 8 is fixed and recorded in the data acquisition sensor 4. In this way, when switching to the water depth mode, the distance between the first sensing slider 7 and the data acquisition sensor 4 can be calculated, and then the length of the multi-level monitoring section can be calculated. Of course, in the longest mode, that is, the first sensing slider 7 moves to the limit part 6 at the lowest position and is restricted, this can be used in environments where there is a large drop between the water surface and the installation part, such as valleys and rivers.

[0051] The movable part includes two sliding rods 9, with both ends of the sliding rods 9 fixedly connected to the mounting ports 71 on the first sensing plug 7 and the second sensing ring 8, respectively. The float level gauge 10 is provided with a 11 that matches the main rod 1, as well as vertical holes that slide on the two sliding rods 9. The sliding rods 9 can be lengthened, can be switched between multiple modes, and can also be used in complex environments.

[0052] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
