Description

Technical Field

[0001] The invention relates to the technical field of water level monitoring, and in particular to a water level monitor for operation and management of a water conservancy project. Background Art

[0002] Water conservancy engineering mainly studies the basic knowledge and skills in engineering hydrology, water conservancy engineering surveying, water conservancy reinforced concrete, hydraulic structures, engineering drawing, etc. It carries out engineering planning and design, on-site construction, engineering budgeting, and water conservancy equipment maintenance and repair in the field of water conservancy engineering. When carrying out water conservancy projects, water level monitors are needed to monitor the water level in real time so that the staff can understand the rise and fall of the water level.

[0003] A water level monitor is an instrument used to measure the surface height of water bodies such as rivers, lakes, and reservoirs. A water level monitor can monitor changes in river water levels in real time. Existing water level monitors usually use radar water level monitors to measure water levels. The radar measuring instrument is supported by a support frame. The microwave signal emitted by the radar water level monitor will propagate toward the water surface and be reflected back when it encounters the liquid level surface. The instrument calculates the height of the liquid level by measuring the time required for the signal to be transmitted and received, that is, the flight time. Because the propagation speed of radar waves in the air is constant, the liquid level height can be accurately determined by calculating the flight time. This method is more suitable for some calm rivers, but it is not suitable for areas with turbulent water flow and frequent waves. Because the water surface floats to a large extent, the above-mentioned method is often used for monitoring, which often results in the monitored value being higher than the actual water level value, resulting in a large error in the actual liquid level detected.

DETAILED DESCRIPTION

[0024] The following is combined with Figure 1 to Figure 6 In order to make the purpose, technical solution and advantages of the embodiment of the present invention clearer, the technical solution of the embodiment of the present invention will be clearly and completely described in conjunction with the drawings of the embodiment of the present invention. Obviously, the described embodiment is a part of the embodiment of the present invention, not all of the embodiments.

Unless otherwise defined, the technical terms or scientific terms used herein should be the usual meanings understood by people with general skills in the field to which the present invention belongs.

Words such as "include" or "comprise" and similar words mean that the elements or objects appearing before the word include the elements or objects listed after the word and their equivalents, but do not exclude other elements or objects. "Inside", "outside", "upper", "lower", "far", "near", "front", "back" and the like are only used to indicate relative positional relationships. When the absolute position of the described object changes, the relative positional relationship may also change accordingly. The drawings in the present invention are not drawn strictly according to the actual proportions. The specific size and quantity of each structure can be determined according to actual needs. The drawings described in the present invention are only schematic diagrams of the structures.

[0026] The present invention provides a water level monitor for water conservancy project operation and management, such as Figure 1 to Figure 4As shown, it includes a support frame 1 and a radar monitor 2 installed on the support frame 1, and also includes a protective tube 3. The protective tube 3 is connected to the support frame 1 through a supporting component 11. The protective tube 3 is vertically lowered into the water flow to be monitored. A floating plate 4 is provided in the protective tube 3. The floating plate 4 slides vertically along the inner wall of the protective tube 3, and the floating plate 4 coincides with the axis of the radar monitor 2 in the vertical direction. A plurality of water inlet holes 5 are opened on the periphery of the protective tube 3, and a plurality of wave-slowing plate groups 6 are provided on the outer side of the protective tube 3. The plurality of wave-slowing plate groups 6 are arranged in an array along the periphery of the protective tube 3.

[0027] The protective tube 3 is lowered into the water flow of the river channel that needs to be inspected through the supporting component 11, and the floating plate 4 in the protective tube 3 is made to coincide with the axis of the radar monitor 2. Since the protective tube 3 is fixedly installed by the supporting component 11, the turbulent river water and waves hit the protective tube 3 and enter the inside of the protective tube 3 through the water inlet hole 5 on the protective tube 3. As the liquid level in the protective tube 3 rises and falls, the floating plate 4 is pushed to move in the vertical direction in the protective tube 3. The microwave signal emitted by the radar monitor 2 collides with the surface of the floating plate 4 and is reflected and then received by the radar monitor 2, thereby real-time monitoring of the river channel page is performed. On the one hand, the protective tube 3 blocks the waves to make the liquid level inside the protective tube 3 stable. On the other hand, the protective tube 3 can also block some aquatic plants and floating objects on the river channel to prevent the aquatic plants and floating objects from refracting the microwave signal emitted by the radar monitor 2 and affecting the monitoring result.

[0028] The wave-slowing plate group 6 is set to mitigate the vibration force exerted on the protective tube 3 when it is hit by waves, reduce the disturbance of the water flow, and further make the liquid level inside the protective tube 3 in a stable state. The cleaning component 7 is set to clean the water inlet hole 5 opened on the protective tube 3 to prevent some floating objects or aquatic plants in the water flow from sticking to the water inlet hole 5, causing the water inlet hole 5 to be blocked, which will cause the water flow entering the protective tube 3 to float and affect the monitoring result of the radar monitor 2.

[0029] Preferably, Figure 1 to Figure 5 As shown, the protective cylinder 3 is composed of an outer cylinder 31 and an inner cylinder 32, and a plurality of water inlet holes 5 are provided on the inner cylinder 32 and the outer cylinder 31, and a buffer member 8 is provided between the inner cylinder 32 and the outer cylinder 31, and the wave-slowing plate group 6 includes a vertically arranged connecting plate 61, and the connecting plate 61 is fixedly connected to the outer side wall of the outer cylinder 31, and a sliding groove 62 is provided in the connecting plate 61 in the horizontal direction, and a first moving rod 63 is slidably arranged in the sliding groove 62, and one end of the first moving rod 63 is fixedly connected to an arc guide plate 64, and the other end is fixedly connected to a first telescopic rod 65, one end of the first telescopic rod 65 is fixedly connected to the connecting plate 61, and the other end is fixedly connected to the first moving rod 63, and a first reset spring 66 is sleeved on the first telescopic rod 65, and one end of the first reset spring 66 is fixedly connected to the connecting plate 61, and the other end is fixedly connected to the first moving rod 63.

[0030] In this embodiment, the protective tube 3 is composed of an outer tube 31 and an inner tube 32, and a buffer member 8 is arranged between the two, so as to further reduce the disturbance effect of waves on the water flow in the inner tube 32 when the waves hit. When the waves hit the set arc guide plate 64, the surging waves are initially buffered. When the arc guide plate 64 is compressed, the set first telescopic rod 65 and the first return spring 66 are pressed by the set moving rod, and the first return spring 66 is used for initial slow release. For some small waves and water flow disturbances, slow release can be performed through the wave-slowing plate group 6. When the waves are large, the outer tube 31 will be displaced. At this time, the impact force on the outer tube 31 is further released through the buffer member 8 between the outer tube 31 and the inner tube 32, so that the water flow in the inner tube 32 is in a stable state.

[0031] Preferably, Figure 1 to Figure 6 As shown, a cleaning piece 7 is provided on the outside of the protective cylinder 3, and the cleaning piece 7 includes a pair of first arc blocks 71. An arc groove 72 for sliding the first arc block 71 is provided on the top of the outer cylinder 31. The first arc block 71 is slidably arranged in the arc groove 72 and performs circular motion around the axis of the outer cylinder 31. One side of the pair of first arc blocks 71 is connected with a scraper plate 73 through a fixed rod. The pair of scraper plates 73 are arranged in a one-to-one correspondence with the pair of first arc blocks 71, and the pair of scraper plates 73 are in contact with the outer wall of the outer cylinder 31. The buffer member 8 includes a horizontally arranged support rod 81, one end of the support rod 81 is fixedly connected to the inner cylinder 32, and the other end is fixedly connected to a bearing groove 82, and a pair of second arc blocks 8 are slidably arranged in the bearing groove 82. 3. A pair of second telescopic rods 84 are fixedly connected in the bearing groove 82, one end of the second telescopic rod 84 is fixedly connected to the second arc block 83, and the other end is fixedly connected to the bearing groove 82. A second return spring 85 is sleeved on the second telescopic rod 84, one end of the second return spring 85 is fixedly connected to the second arc block 83, and the other end is fixedly connected to the bearing groove 82. A pair of hinged rods 86 are hinged in the inner side wall of the outer cylinder 31, one end of the pair of hinged rods 86 is hinged to the second arc block 83, the arc length of the bearing groove 82 is the same as the arc length of the arc groove 72, and the pair of second arc blocks 83 are fixedly connected to the first arc block 71 through a connecting frame 9 respectively, and a plurality of spikes 12 are provided on the side of the connecting plate 61 close to the scraping plate 73.

[0032] When the outer cylinder 31 is displaced by pressure, the second arc block 83 is driven to move through the hinge rod 86, so that the second arc block 83 slides in the bearing groove 82, and squeezes the second telescopic rod 84 and the second return spring 85, further releasing the impact force on the outer cylinder 31, and the second arc block 83 is connected to the first arc block 71 through the connecting frame 9. When the second arc block 83 is displaced, the first arc block 71 slides in the arc groove 72 synchronously, and the scraper plate 73 is connected to the first arc block 71 through the fixing rod 9. The first arc block 71 is fixedly connected, and the scraper plate 73 will move with the first arc block 71 to scrape the surface of the filter hole opened on the outer cylinder 31 to prevent aquatic plants and floating objects in the water flow from blocking the water inlet hole 5, and the scraper plate 73 will push the floating objects and aquatic plants on the spikes 12 to limit them when pushing. This embodiment cleverly utilizes the impact force of the water flow, and while slowly releasing the impact force of the waves, it also cleans the water inlet hole 5 on the outer cylinder 31, without adding an external drive. The design is clever and saves energy.

[0033] Preferably, Figure 1-2 As shown, the support frame 1 includes a column 101, a base 102, a load-bearing rod 103 and a reinforcement rod 104. The base 102 is fixedly connected to the bottom end of the column 101 and installed on the ground. The load-bearing rod 103 is horizontally arranged, one end of which is fixedly connected to the top of the column 101, and the other end is connected to the radar monitor 2. The reinforcement rod 104 is tilted and one end is fixedly connected to the load-bearing rod 103, and the other end is fixedly connected to the column 101. The support component 11 includes a first rod member 111, a second rod member 112 and a connecting ring 113. The first rod member 111 is horizontally arranged, one end is fixedly connected to the column 101, and the other end is fixedly connected to the second rod member 112. The second rod member 112 is vertically arranged, one end is fixedly connected to the connecting ring 113, and the connecting ring 113 is installed on the top of the inner tube 32 by bolts. An alarm 10 is provided on the column 101.

[0034] The column 101 is installed on the ground through the base 102. The column 101 supports the support rod 103. The radar monitor 2 is installed on the support rod 103. The inclined reinforcement rod 104 is used to improve the stability of the support rod 103. A solar panel can be set on the top of the column 101 to generate electricity to supply energy to the radar monitor 2. The present invention sets an alarm 10 on the column 101. When the radar monitor 2 detects that the water level is too high, a trapezoidal alarm is issued in time. When the water level is too low, it will cause a certain impact on the ecology of the river. When the water level of the river is lower than a certain level, the alarm 10 will also sound an alarm. At this time, the use of river water should be stopped until the river water level is at a safe water level.

[0035] The method of using the water level monitor for water conservancy project operation management of the present invention is as follows:

[0036] The column 101 is installed on the ground through the base 102. The column 101 supports the supporting rod 103. The radar monitor 2 is installed on the supporting rod 103. The protective tube 3 is lowered into the water flow to be monitored through the first rod body, the second rod body and the connecting ring 113, and the floating plate 4 in the protective tube 3 coincides with the axis of the radar monitor 2.

[0037] When the waves hit the arc guide plate 64, the surging waves are initially buffered. When the arc guide plate 64 is compressed, the first telescopic rod 65 and the first return spring 66 are pressed through the movable rod, and the first return spring 66 performs initial slow release. For some small waves and water disturbances, the slow release can be performed through the wave-slowing plate group 6. When the waves are large, the outer cylinder 31 will be displaced.

[0038] When the outer cylinder 31 is displaced by pressure, the second arc block 83 is driven to move through the hinge rod 86, so that the second arc block 83 slides in the bearing groove 82, and squeezes the second telescopic rod 84 and the second return spring 85, further releasing the impact force on the outer cylinder 31, and the second arc block 83 is connected to the first arc block 71 through the connecting frame 9. When the second arc block 83 is displaced, the first arc block 71 slides in the arc groove 72 synchronously, and the scraper plate 73 is connected to the first arc block 71 through the fixing rod 9. The first arc block 71 is fixedly connected, and the scraper plate 73 will move with the first arc block 71 to scrape the surface of the filter hole opened on the outer cylinder 31 to prevent aquatic plants and floating objects in the water flow from blocking the water inlet hole 5, and the scraper plate 73 will push the floating objects and aquatic plants on the spikes 12 to limit them when pushing. This embodiment cleverly utilizes the impact force of the water flow, and while slowly releasing the impact force of the waves, it also cleans the water inlet hole 5 on the outer cylinder 31, without adding an external drive. The design is clever and saves energy.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
