Description

Technical Field

[0001] The utility model belongs to the technical field of water level monitoring, and specifically relates to a water level monitoring buoy for water conservancy projects. Background Technique

[0002] During the flood season, a key period with frequent natural disasters, the water level monitoring of rivers, lakes and channels is particularly important, which is directly related to the timeliness and effectiveness of flood control and disaster reduction. At present, one of the widely used water level monitoring methods is to deploy water level monitoring buoys in water areas to achieve real-time and continuous collection of water level data. These buoys are equipped with advanced sensors and communication modules, which can accurately sense water level changes and transmit them to the monitoring center immediately, providing important basis for decision-making support.

[0003] However, although this monitoring method performs well in most cases, its stability becomes a major challenge in the face of extreme weather conditions, such as strong winds and huge waves caused by typhoons and heavy rains. The violently fluctuating water surface will not only cause violent impacts and shakes on the buoy, but also the long-term beating may cause the buoy to capsize or even be damaged, thus interrupting the monitoring activities and seriously affecting the continuity and accuracy of the data. In addition, the capsizing of the buoy may also increase the maintenance cost, requiring professional personnel to quickly intervene for repair or replacement, which is particularly inconvenient during the emergency flood control period. Content of the Utility Model

[0004] To solve the problems raised in the above background technique, the utility model provides a water level monitoring buoy for water conservancy projects.

[0005] To achieve the above object, the utility model provides the following technical solution: A water level monitoring buoy for water conservancy projects, including a main floating board and an annular floating board. A connecting rod is fixedly installed between the main floating board and the annular floating board. An annular groove is opened inside the annular floating board. A detection radar is arranged at the bottom of the annular floating board. A cross groove is opened at the top of the main floating board. A hydraulic cylinder is fixedly installed inside the cross groove. A movable rod is movably installed inside the hydraulic cylinder. The other end of the movable rod is fixedly installed with a connecting plate. A signal receiving module is fixedly installed at the top of the main floating board. A hemispherical block is fixedly installed at the bottom of the main floating board. A weight ball is fixedly installed at the bottom of the hemispherical block.

[0006] Preferably, the number of the detection radars is three groups, and the three groups of detection radars are evenly distributed at the bottom of the annular floating board.

[0007] Preferably, a cover plate is movably installed at the top of the main floating board. A circular groove is opened on the surface of the cover plate and extends into the main floating board. A bolt is movably installed inside the circular groove.

[0008] Preferably, there are four sets of the connecting plates, and the distances between every two adjacent sets of the connecting plates are equal.

[0009] Preferably, the outer diameter value of the connecting plate is equal to the inner diameter value of the annular groove, and the connecting plate is made of plastic.

[0010] Preferably, there are two bolts, and the two bolts are symmetrically distributed on the top of the cover plate of the main floating plate.

[0011] Preferably, the whole weight ball is made of stainless steel, and there are four sets of the connecting rods, and the sizes of each set of the connecting rods are equal.

[0012] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0013] The present utility model places the device in the water body, collects the water level data through the detection radar, and transmits the collected result to the signal receiving module. The signal receiving module analyzes the collected result and wirelessly transmits it to the Bluetooth device for the staff to view. When bad weather occurs, the power of the hydraulic cylinder makes the connecting plate enter the inside of the annular groove through the movable rod, thereby increasing the area. Compared with the traditional device, this device makes the device increase the floating area in bad weather, reduces the swaying amplitude of the float, enables it to float more stably on the water surface, ensures the accuracy and continuity of the water level monitoring data. At the same time, the increased floating area means a larger water resistance area, which helps to disperse and resist the impact of wind and waves on the float, reduces the risk of float damage caused by the direct action of wind and waves, and the stable float can more accurately reflect the true situation of the water level, avoiding fluctuations or errors in the monitoring data caused by the swaying of the float, so as to provide more reliable data support.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 5 shown, the present invention provides a water level monitoring float for water conservancy projects, including a main floating board 1 and an annular floating board 2. A connecting rod 3 is fixedly installed between the main floating board 1 and the annular floating board 2. An annular groove 11 is opened inside the annular floating board 2. A detection radar 6 is arranged at the bottom of the annular floating board 2. A cross groove 7 is opened at the top of the main floating board 1. A hydraulic cylinder 8 is fixedly installed inside the cross groove 7. A movable rod 9 is movably installed inside the hydraulic cylinder 8. The other end of the movable rod 9 is fixedly installed with a connecting plate 10. A signal receiving module 15 is fixedly installed at the top of the main floating board 1. A hemispherical block 4 is fixedly installed at the bottom of the main floating board 1. A weight ball 5 is fixedly installed at the bottom of the hemispherical block 4;

[0022] Adopting the above solution: Through this device, the device increases the floating area in bad weather, reduces the swaying amplitude of the float, enables it to float more stably on the water surface, ensures the accuracy and continuity of water level monitoring data. At the same time, the increased floating area means a larger water resistance area, which helps to disperse and resist the impact of wind and waves on the float, reduces the risk of float damage caused by the direct action of wind and waves, and the stable float can more accurately reflect the true situation of the water level, avoiding fluctuations or errors in monitoring data caused by the swaying of the float, so as to provide more reliable data support.

[0023] As Figure 3 shown, there are three groups of detection radars 6, and the three groups of detection radars 6 are evenly distributed at the bottom of the annular floating board 2. A cover plate 12 is movably installed at the top of the main floating board 1. A round groove 13 is opened on the surface of the cover plate 12 and extends into the main floating board 1. A bolt 14 is movably installed inside the round groove 13;

[0024] Adopt the above solution: By arranging three groups of detection radars 6 and evenly distributing the three groups of detection radars 6 at the bottom of the annular floating plate 2, the detection accuracy is improved. By movably installing a cover plate 12 on the top of the main floating plate 1, a circular groove 13 is opened on the surface of the cover plate 12 and extends into the main floating plate 1, and a bolt 14 is movably installed in the circular groove 13, so as to ensure that the hydraulic cylinder 8 is not eroded by water during use.

[0025] As Figure 1 , Figure 4 shown, there are four groups of connecting plates 10, the distance between each adjacent two groups of connecting plates 10 is equal, the outer diameter value of the connecting plate 10 is equal to the inner diameter value of the annular groove 11, and the connecting plate 10 is made of plastic;

[0026] Adopt the above solution: By arranging four groups of connecting plates 10 and making the distance between each adjacent two groups of connecting plates 10 equal, the stability of the device in bad weather is improved. By setting the outer diameter value of the connecting plate 10 to be equal to the inner diameter value of the annular groove 11, the connecting plate 10 fits better when entering the inside of the annular groove 11. The connecting plate 10 is made of plastic, and the plastic is lighter in weight and cheaper in price.

[0027] As Figure 1 shown, there are two bolts 14, and the two bolts 14 are symmetrically distributed on the top of the cover plate 12 of the main floating plate 1. The weight ball 5 is entirely made of stainless steel. There are four groups of connecting rods 3, and the size of each group of connecting rods 3 is equal.

[0028] Adopt the above solution: By arranging two bolts 14 and symmetrically distributing the two bolts 14 on the top of the cover plate 12 of the main floating plate 1, the cover plate 12 can be better fixed on the top of the main floating plate 1 to ensure the integrity of the internal components of the main floating plate 1. By making the weight ball 5 entirely made of stainless steel, the stainless steel has high strength and good rust prevention performance. By arranging four groups of connecting rods 3 and making the size of each group of connecting rods 3 equal, the connection between the main floating plate 1 and the annular floating plate 2 is strengthened.

[0029] The working principle and usage process of the present utility model:

[0030] During use, the staff place the device in the water body. The counterweights of the hemispherical block 4 and the weighted ball 5 ensure that the device does not tilt or overturn in the water body. Subsequently, the detection radar 6 collects the water level of the water body, and transmits the collected result wirelessly to the signal receiving module 15. The signal receiving module 15 analyzes the collected result and transmits the analyzed result to the Bluetooth device for the staff to view. When bad weather occurs, the staff start the hydraulic cylinder 8. The thrust of the hydraulic cylinder 8 pushes the movable rod 9 to move, so that the connecting plate 10 at one end of the movable rod 9 gradually approaches the annular floating plate 2 and finally enters the inside of the annular groove 11, thereby increasing the overall area of the device.
