Description

Technical Field

[0001] The utility model relates to the field of water level measuring devices, in particular to a water level measuring device for operation and management of a water conservancy project reservoir. Background Art

[0002] A water level measuring device is an important tool for accurately measuring the height of a water body. It is usually composed of a series of sensors, measuring instruments and related transmission and display equipment. These devices can monitor changes in water levels in real time and accurately feed back data to users. Whether in water conservancy projects, water resources management, environmental protection or other water-related fields, water level measuring devices play a vital role, providing people with key information about water conditions and helping people better understand and manage water resources. Therefore, water level measuring devices are needed for the operation and management of water conservancy projects and reservoirs, which can assist in measuring the water level in water conservancy project reservoirs.

[0003] Existing water level measurement devices used in the operation and management of water conservancy project reservoirs operate based on the principle of pressure sensors. By installing pressure sensors at specific locations within the reservoir, they detect changes in water pressure as the water level changes. The sensors sense these pressure changes and convert them into electrical signals, which are then transmitted to a processing unit for analysis and calculation, resulting in an accurate water level reading. The devices also record and display real-time water level data, allowing managers to monitor reservoir water level conditions at all times and ensure the safe and efficient operation of water conservancy projects.

[0004] However, in the actual use of water level measuring devices for the operation and management of water conservancy projects and reservoirs, there has always been a serious problem that has not been properly solved. That is, when the water flow speed is too fast, the float will float to a large extent due to the impact of the water flow, causing it to float too far. In this way, the cable connected to the float will be over-stretched. The overly long cable will have an adverse effect on data transmission, resulting in inaccurate data transmission, affecting the practicality of the water level measuring device for the operation and management of water conservancy projects and reservoirs. Utility Model Content

[0005] In order to make up for the above shortcomings, the utility model provides a water level measuring device for operation and management of water conservancy project reservoirs, aiming to improve the problem that when the water flow is too fast, the float floats too far, causing the cable to stretch too long and thus leading to inaccurate data transmission.

[0006] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solutions: a water level measuring device for operation and management of a water conservancy project reservoir, comprising a bank, a box body fixedly connected to one side of the bank, a display screen provided on one side of the box body, a dust cover fixedly connected to one side of the box body, a heat dissipation hole provided on one side of the dust cover, a collection rod rotatably connected to the inner wall of the box body, a cable reel fixedly connected to the outer wall of the collection rod, a motor fixedly connected to the outer wall of the box body, an output end of the motor fixedly connected to one end of the collection rod, a conveying rod fixedly connected to the outer wall of the conveying rod, a transmission line rotatably connected to one end of the transmission line, a measuring component provided on the outer wall of the box body;

[0007] The limiting assembly includes a fixing plate and a limiting column. One side of the fixing plate is fixedly connected to the outer wall of the box body, and one end of the limiting column is fixedly connected to one side.

[0008] As a further description of the above technical solution:

[0009] The measuring component includes a float and a sensor. One end of the float is fixedly connected to one end of the transmission line, and one end of a plurality of sensors is electrically connected to the surface of the float.

[0010] As a further description of the above technical solution:

[0011] The outer wall of the fixing plate is fixedly connected with fixing columns arranged in a linear array, and one end of each of the fixing columns is fixedly connected with an extension column.

[0012] As a further description of the above technical solution:

[0013] A locking column is provided on one side of the extension column, and each end of the locking column is fixedly connected to a plurality of connecting columns.

[0014] As a further description of the above technical solution:

[0016] As a further description of the above technical solution:

[0024] 2. In the utility model, a detachable wire mesh and a corresponding disassembly device are added to achieve the effect of intercepting relatively large stones in the water body near the float, solving the problem that when the water flow is too turbid, the larger stones in it will damage the sensor in the float, resulting in inaccurate transmitted data, thereby improving the safety of the water level measuring device used in the operation and management of water conservancy projects and reservoirs.

[0033] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0034] Reference Figures 1-4 The utility model provides an embodiment of a water level measuring device for operation and management of a water conservancy project reservoir, comprising a bank 1, a box body 2 fixedly connected to one side of the bank 1, a display screen 3 is provided on one side of the box body 2 for displaying measurement data in real time, a dust cover 4 is fixedly connected to one side of the box body 2 to prevent dust from entering the box body 2 and protecting the normal operation of the internal components, a heat dissipation hole 20 is opened on one side of the dust cover 4, the inner wall of the box body 2 is rotatably connected to a collecting rod 5, which can store and release a cable roll 6 to ensure that the cables are neat and orderly, the outer wall of the collecting rod 5 is fixedly connected to the cable roll 6, the outer wall of the box body 2 is fixedly connected to a motor 7, the rotation of the collecting rod 5 provides power, the output end of the motor 7 is fixedly connected to one end of the collecting rod 5, the inner wall of the box body 2 is fixedly connected to a conveying rod 8, which plays the role of guiding and supporting a transmission line 9, the outer wall of the conveying rod 8 is rotatably connected to a transmission line 9 for transmitting the measurement data to the display screen 3, a measuring component is provided at one end of the transmission line 9, which is responsible for measuring the water level, and a limit component is provided on the outer wall of the box body 2;

[0035] The limiting assembly includes a fixing plate 10 and a limiting column 11. One side of the fixing plate 10 is fixedly connected to the outer wall of the box body 2 for fixing the limiting column 11 on the box body 2. One end of the limiting column 11 is fixedly connected to one side of 10. The measuring assembly includes a float 12 and a sensor 13. One end of the float 12 is fixedly connected to one end of the transmission line 9. One end of multiple sensors 13 is fixedly connected to the surface of the float 12, which can accurately sense the change in water level and transmit data to the display screen 3. Each limiting column 11 is parallel to each other and arranged on opposite sides. One side of the fixing plate 10 is fixedly connected to the bottom side of the box body 2, providing an installation position for the limiting column 11 and the wire mesh 19. Each heat dissipation hole 20 is arranged in parallel, and the collecting rod 5 and the transport rod 8 are arranged in parallel.

[0036] Specifically, the heat dissipation holes 20 on the dust cover 4 are regularly arranged parallel to each other. This parallel arrangement ensures that the air can flow smoothly between the heat dissipation holes 20, thereby greatly improving the heat dissipation efficiency inside the box 2. The float 12 in the measuring component generally adopts a plastic shell and adds a counterweight block inside so that it can float up and down with the rise and fall of the water level. At the same time, the collecting rod 5 and the conveying rod 8 are arranged parallel to each other. Such a parallel layout allows the transmission line 9 on the cable reel 6 to be smoothly wound and extended, ensuring that the measurement work can be carried out smoothly without any obstruction or interference. The limit columns 11 are installed around the float 12 on opposite sides and parallel to each other, which can enable the float 12 to float within a certain range and is not easy for the float 12 to float too far with the water flow, thereby affecting the measurement data.

[0037] Reference Figure 5 and Figure 6 The outer wall of the fixing plate 10 is fixedly connected with a fixing column 14 arranged in a straight line array, providing a stable connection and support for the extension column 15. One end of each fixing column 14 is fixedly connected to an extension column 15, which can clamp the positioning column 16 to prevent the wire mesh 19 from falling off. A positioning column 16 is provided on one side of the extension column 15. Each end of the positioning column 16 is fixedly connected to a plurality of connecting columns 17. One end of the connecting column 17 is fixedly connected to a ring 18 to fix the wire mesh 19. The inner wall of the ring 18 is fixedly connected to the wire mesh 19 to protect the float 12 from being damaged by large stones in the water, thereby affecting the measurement. Each limiting column 11 is arranged in a circular array, which can play a role in limiting and fixing the float 12. One side of the fixing plate 10 is fixedly connected to the bottom side of the box body 2, and one side of the dust cover 4 is provided with a heat dissipation hole 20 arranged in a straight line array. The collecting rod 5 and the transport rod 8 are arranged in a straight line array, and the ring 18 is in a circular ring shape, which is used to firmly fix the wire mesh 19.

[0038] Specifically, the positioning column 16 is precisely stuck on the fixing column 14 and the extension column 15, like a buckle, firmly fixing the entire wire mesh 19 on the fixing plate 10, and the ring 18 is firmly fixed on one of the knots at the top of the wire mesh 19, and this specific position can be flexibly changed according to actual needs, which is very convenient and practical. In addition, the material selection of the wire mesh 19 can be either soft or hard, which depends entirely on the size of the water flow. If the water flow is large, you can choose a hard wire mesh 19 to better resist the impact of the water flow. If the water flow is small, the soft wire mesh 19 can be more in line with actual needs, showing its unique adaptability and flexibility, so that the entire device can more perfectly adapt to different working environments.

[0039] Working principle: In the process of using the water level measuring device for the operation and management of water conservancy project reservoirs, first install the box body 2 on the horizontal surface of the shore 1. After ensuring that it is firmly installed, first combine the connecting component and the fixing component to install the wire mesh 19 and place it in the water body, and then install the limit column 11 on the fixing plate 10 from the hole opened in the fixing plate 10, and then lower the float 12 from the hole opened in the fixing plate 10, extend the transmission line 9 so that the upper hemisphere of the float 12 just floats on the water surface, and then use the display screen 3 to adjust the internal data to the required data. When the water level rises, the sensor 13 on the float 12 will sense the pressure change and emit a signal, which is transmitted into the device through the transmission line 9. At this time, the device will start the motor 7 to drive the collecting rod 5 to reel inward the transmission line 9 in the groove on the conveying rod 8, thereby lifting the float 12, and then completing the water level rising operation. When the water level drops, the opposite is done.

[0040] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
