Description

Technical Field

[0001] The present invention relates to the technical field of water level monitoring of water channels, and particularly to a real-time monitoring device for water level of channels. Background Art

[0002] Water resources are irreplaceable natural resources on which human beings depend for survival and development, and are the lifeblood of agricultural development. Agricultural irrigation water accounts for 70% of the total national water consumption. The water conveyance monitoring, water-saving dispatching and safety management of irrigation areas are related to national food security, flood control safety and social stability. Irrigation channels are the channels at all levels that introduce the water in the reservoir into the fields through certain dams, certain channels and certain measures. Generally, they are divided into five levels: main canals, branch canals, distributary canals, field canals and capillary canals. The water level information monitoring of agricultural irrigation water channels can not only enable the management department to understand the hydrological conditions of each section of the channels in time and take corresponding measures, but also the water level information of the irrigation channels itself is the basic data for calculating water consumption, providing data support for the pricing of water consumption of irrigation channels later.

[0003] At present, the method for measuring the water level of channels is mainly to install a support rod on the side of the channel, and then install corresponding electrical cabinets, water level gauges, etc. on the support rod. However, as time goes by, the ground near the channel may become uneven due to land subsidence and rain erosion, resulting in a non-horizontal situation between the measuring device and the channel, affecting the measurement accuracy of the measuring device. At the same time, its electronic equipment is exposed to the external environment with low protection, resulting in an increase in the maintenance cost of the equipment. Therefore, the present invention proposes a real-time monitoring device for water level of channels to solve the problems existing in the prior art. Summary of the Invention

[0021] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with examples. The examples are only used to explain the present invention and do not constitute a limitation on the protection scope of the present invention.

[0022] according to Figure 1-Figure 5 As shown, this embodiment provides a real-time monitoring device for channel water level, including an upper cover plate 1 and a ditch 26 for irrigation. Figure 1As shown in the figure, after the upper cover plate 1 is installed, its two sides are located on the two sides above the ditch 26 and are fixedly connected to the ground on both sides of the ditch 26. An installation opening is provided on the upper cover plate 1, and a housing 2 is installed on the installation opening. Extension parts are provided on both the left and right sides of the housing 2, and the extension parts are connected to the upper cover plate 1 by bolts. Thus, when maintenance of the electronic components inside the housing 2 is required, the staff can use tools to unscrew the bolts, and then the upper cover plate 1 can be removed, and subsequent maintenance work can be carried out. On the one hand, the maintenance work does not have to be carried out on site. On the other hand, the maintenance work can be carried out in a safe place, improving convenience.

[0023] A power supply component is installed on the housing 2. The power supply component includes two groups of symmetrically arranged solar photovoltaic panels 11. The lower part of the solar photovoltaic panel 11 is connected to the housing 2 through a fixed sleeve 12, and the inner cavity of the fixed sleeve 12 communicates with the housing 2. In this embodiment, the inner side of the fixed sleeve 12 is hollow, and each group of solar photovoltaic panels 11 is connected to the housing 2 through two fixed sleeves 12. The purpose is to facilitate the entry of cables and provide a protection effect. Correspondingly, a battery pack 13 is provided inside the housing 2, and the battery pack 13 is connected to the baffle 5 through a bracket. The battery pack 13 is electrically connected to the control computer 6 and the solar photovoltaic panel 11. Thus, this device uses solar energy for power supply, playing a role in energy conservation and emission reduction, and also bringing certain convenience.

[0024] A support frame 3 is provided below the upper cover plate 1, and the cross-section of the support frame 3 is in a U shape. Both sides above the support frame 3 are connected to the upper cover plate 1 through a connecting frame 4, as Figure 1 shown. When this device is installed, both ends of the upper cover plate 1 are in a fixed state, and then supported by the cooperation of the support frame 3 and the connecting frame 4, ensuring the horizontality and stability between the upper cover plate 1 and the ditch 26, improving the continuity of water level monitoring, and reducing the maintenance cost of the device.

[0025] A baffle 5 is installed on the inner side of the outer shell 2, and a control computer 6 is installed below the baffle 5. The control computer 6 is electrically connected to the power supply assembly. The control computer 6 is responsible for some data calculations in the device. At the same time, the control computer 6 also has a built-in network communication chip for transmitting the data monitored by the device to the monitoring center through the network (for long distances, it is transmitted to the relay station through the network, and then transmitted to the monitoring center through the relay station). It also has a memory for local storage of related data. A protective plate 7 is installed below the outer shell 2, and the lower part of the protective plate 7 A fixing seat 8 is installed at the end, a radar level meter 9 is installed at the lower end of the fixing seat 8, and a camera 10 is installed on the fixing seat 8. The radar level meter 9 and the camera 10 are both electrically connected to the control computer 6. At the same time, an opening 21 is provided on the support frame 3. The detection end of the radar level meter 9 passes through the opening 21. The radar level meter 9 is in a vertical state. The radar level meter 9 is used to detect the water level in the channel, and the camera 10 is used to provide corresponding pictures. The combination of the two can avoid abnormal situations in a single monitoring method, resulting in the ineffectiveness of the detection. In this embodiment, the camera 10 is a 360° camera.

[0026] Two groups of symmetrically arranged low water level sensors 14 are installed on the inner side of the support frame 3, and a high water level sensor 15 is installed on the connecting frame 4. The low water level sensor 14 and the high water level sensor 15 are both electrically connected to the control computer 6. Furthermore, a preset sensor method is used to sense the low water level and the high water level, and the channel water level monitoring method is more diversified. In this embodiment, the water level sensed by the high water level sensor 15 is higher than the camera 10 and the radar level gauge 9. In the normal position, the water level line in the channel is within the monitoring range of the radar level gauge 9. When an abnormal situation occurs, causing the water level to submerge the radar level gauge 9 and the camera 10, it is sensed by the high water level sensor 15, and its sensing signal is sent to the control computer 6, which performs corresponding processing and transmission. The high water level sensor 15 is a warning water level line, which requires staff to perform subsequent processing.

[0027] Furthermore, drainage holes 19 are provided on both sides of the upper cover plate 1 , and an inclined drainage structure 20 is provided inside the drainage holes 19 . The drainage holes 19 are provided to prevent water from accumulating on the upper cover plate 1 .

[0028] At the same time, ventilation cylinders 22 are installed on both the front and rear sides of the outer shell 2, and ventilation fans 23 are installed on the inner side of the ventilation cylinders 22, and the ventilation fans 23 are provided in several groups. In this embodiment, two groups of ventilation fans 23 are installed in each group of ventilation cylinders 22, and ventilation holes are provided on both the front and rear sides of the outer shell 2, and the positions and numbers of the ventilation holes correspond to the ventilation fans 23. The ventilation fans 23 are electrically connected to the battery pack 13 and are controlled by the control computer 6. A dustproof net 24 is installed at one end of the ventilation cylinder 22 away from the outer shell 2, and a drainage hole 25 is installed on the side of the ventilation cylinder 2 close to the outer shell 2, and the drainage holes 25 are evenly provided in several groups, such as Figure 5 As shown, there is a distance between the ventilation fan 23 and the vent. The purpose is that when rainwater splashes in from the outside, it cannot directly enter the outer shell 2 from the vent. Therefore, it will first be located in the ventilation tube 22 and then drained through the provided drainage hole 25. Therefore, the device not only has a heat dissipation effect, but also has a waterproof effect, thereby ensuring the continuous operation of the device.

[0029] Threaded holes 16 are provided on both sides (left and right sides) of the support frame 3, and the threaded holes 16 are provided in several groups. In this embodiment, two groups of threaded holes 16 are provided on the left and right sides of the support frame 3, and a limiting opening 17 is provided on the connecting frame 4, and the limiting opening 17 is provided in several groups. The number of the limiting openings 17 corresponds to the threaded holes 16, that is, two groups of limiting openings 17 are provided on the connecting frame 4, and a locking member 18 is installed on the limiting opening 17, and the locking member 18 is connected to the threaded holes 16 at the corresponding positions, such as Figure 1 As shown, the locking member 18 corresponds to a bolt. When it is connected to the threaded hole 16 and tightened, it has a clamping and fixing effect on the connecting plate 4. Furthermore, under the action of the limit opening 17, the distance between the connecting frame 4 and the supporting frame 3 can be adjusted, and the adjustment range is the length of the limit opening 17, thereby adapting to the requirements of different channel depths.
