Description

Technical Field

[0001] The utility model relates to the technical field of water level gauges, in particular to a water level gauge for hydraulic engineering. Background Art

[0002] The water level gauge in water conservancy projects, also known as the water gauge, is a scale used to directly observe and record the water level of rivers, lakes, reservoirs, irrigation canals and other water bodies. This scale is usually made of metal or non-metallic materials, with scales marked on it, which can intuitively read the height of the water level, making it convenient for managers to control and dispatch the water level.

[0003] At present, the water level gauge of hydraulic engineering is usually a kind of benchmark with scale, and when it is used, it needs to be lowered and inserted into the river channel, and the bottom of the water level gauge is fixed to the river bottom. When the water level changes, the scale exposed above the water surface will change, and the water level situation is judged according to the change data of the scale. However, this will cause the scale to be immersed in the river water for a long time. The mud and debris in the river water can easily adhere to the outer surface of the water level gauge, and the scale is easily blocked, which will make reading difficult. Therefore, a water level gauge for hydraulic engineering is needed to solve the above problems. Utility Model Content

[0004] The purpose of the present invention is to solve at least one of the above technical deficiencies.

[0005] Therefore, one purpose of the utility model is to provide a water level gauge for hydraulic engineering to solve the problems mentioned in the background technology and overcome the deficiencies in the prior art.

[0006] In order to achieve the above-mentioned purpose, an embodiment of the utility model on one hand provides a water level gauge for a hydraulic project, including an installation base plate, the top surface of the installation base plate is fixedly connected to a support plate, the outer surface of the support plate is slidably connected to a lifting frame, the side of the support plate is fixedly connected to a connecting plate, the outer side of the connecting plate is fixedly connected to a pointer, the outer surface of the lifting frame is provided with a scale bar, the pointer corresponds to the scale bar, the bottom surface of the lifting frame is fixedly connected to a hollow floating plate, the side of the installation base plate is rotatably connected to a rotating shaft, the outer side of the rotating shaft is fixedly connected to a rotating frame, the top of the rotating frame is threadedly connected to a threaded column, the bottom of the threaded column is rotatably connected to a pressure plate through a bearing, and the pressure plate is in conflict with the hollow floating plate.

[0007] Preferably, any of the above schemes is that a rotation hole is opened on the side of the mounting base plate, the rotation shaft is rotatably connected to the mounting base plate through the rotation hole, and the rotating frame is slidably connected to the mounting base plate.

[0008] Preferably, any of the above schemes is that two guide rods are fixedly connected to the top surface of the pressure plate, the two guide rods are symmetrically distributed on both sides of the threaded column, and the guide rods are slidably connected to the rotating frame.

[0009] Preferably, any of the above schemes is that a connecting groove is provided on the side of the lifting frame, and the connecting plate is slidably connected to the lifting frame through the connecting groove.

[0010] Preferably, any of the above schemes is that one side of the lifting frame is fixedly connected to a limiting column, the side surface of the support plate is fixedly connected to a limiting plate, and the limiting column is slidably connected to the limiting plate.

[0011] Preferably, any of the above schemes is that the inner wall of the lifting frame is rotatably connected to a plurality of rollers, the plurality of rollers are linearly arrayed inside the lifting frame, and the rollers are slidably connected to the support plate.

[0012] Compared with the prior art, the advantages and beneficial effects of the utility model are:

[0013] When the water level gauge needs to be used, the rotating frame can be pushed to rotate its rotating shaft until the rotating frame is perpendicular to the mounting base plate, and then the threaded column can be rotated. The threaded transmission can drive the pressure plate to move downward. The downward movement of the pressure plate will drive the guide rod to slide relative to the rotating frame, and the pressure plate can be limited until the pressure plate conflicts with the hollow floating plate. The hollow floating plate can be assembled with the mounting base plate to prevent the hollow floating plate from sliding on the outer surface of the support plate, which can make it easier to carry the water level gauge and carry the water level gauge to the use position. Then release the lock of the hollow floating plate by the pressure plate, and install the installation base plate on the river bottom. At this time, the hollow floating plate will be affected by the buoyancy in the water, and the lifting frame will be driven to slide upward along the support plate under the action of buoyancy. At this time, the pointer will move relative to the scale bar, and then the length of the support plate exposed above the water surface can be read. The length of the support plate minus the reading is the water level height, and the support frame can always be located above the water level due to the hollow floating plate floating on the water surface, thereby preventing the scale bar from contacting the river water, and preventing mud and debris from easily adhering to the outer surface of the scale bar.

DETAILED DESCRIPTION

[0022] The utility model is further described below in conjunction with the accompanying drawings, but the protection scope of the utility model is not limited to the following.

[0023] like Figures 1 to 7 As shown, a water level gauge for a hydraulic project comprises a mounting base plate 1, the top surface of the mounting base plate 1 is fixedly connected to a support plate 2, the outer surface of the support plate 2 is slidably connected to a lifting frame 3, the side of the support plate 2 is fixedly connected to a connecting plate 4, the outer side of the connecting plate 4 is fixedly connected to a pointer 5, the outer surface of the lifting frame 3 is provided with a scale bar 6, the pointer 5 corresponds to the scale bar 6, the bottom surface of the lifting frame 3 is fixedly connected to a hollow floating plate 7, the side of the mounting base plate 1 is rotatably connected to a rotating shaft 8, the outer side of the rotating shaft 8 is fixedly connected to a rotating frame 9, the top of the rotating frame 9 is threadedly connected to a threaded column 10, the bottom of the threaded column 10 is rotatably connected to a pressure plate 11 through a bearing, and the pressure plate 11 is in conflict with the hollow floating plate 7.

[0024] As an optional technical solution of the utility model, a rotating hole 12 is opened on the side of the mounting base plate 1, and the rotating shaft 8 is rotatably connected to the mounting base plate 1 through the rotating hole 12. The rotating frame 9 is slidably connected to the mounting base plate 1, and the rotating frame 9 can be pushed to rotate the rotating shaft 8, thereby preventing the rotating frame 9 from interfering with the lifting and lowering of the hollow floating plate 7.

[0025] As an optional technical solution of the present invention, two guide rods 13 are fixedly connected to the top surface of the pressure plate 11. The two guide rods 13 are symmetrically distributed on both sides of the threaded column 10. The guide rods 13 are slidably connected to the rotating frame 9. When the pressure plate 11 moves downward, it will drive the guide rods 13 to slide relative to the rotating frame 9, thereby limiting the position of the pressure plate 11.

[0026] As an optional technical solution of the present invention, a connection groove 14 is provided on the side of the lifting frame 3 , and the connection plate 4 is slidably connected to the lifting frame 3 through the connection groove 14 .

[0027] As an optional technical solution of the present invention, a limiting column 15 is fixedly connected to one side of the lifting frame 3, and a limiting plate 16 is fixedly connected to the side of the support plate 2. The limiting column 15 is slidably connected to the limiting plate 16. When the lifting plate 3 is lifted or lowered, the limiting column 15 will be driven to slide relative to the limiting plate 16, thereby limiting the movement of the lifting frame 3.

[0028] As an optional technical solution of the present invention, the inner wall of the lifting frame 3 is rotatably connected to a plurality of rollers 17, and the plurality of rollers 17 are linearly arrayed inside the lifting frame 3. The rollers 17 are slidably connected to the support plate 2. The setting of the rollers 17 can reduce the contact area between the lifting frame 3 and the support plate 2 and thereby reduce the friction between the two.

[0029] A water level gauge for a hydraulic project, the working principle is as follows:

[0030] 1): When the water level gauge needs to be used, the rotating frame 9 can be pushed to rotate the rotating shaft 8 until the rotating frame 9 is perpendicular to the mounting base plate 1, and then the threaded column 10 is rotated. The pressing plate 11 can be driven downward by the threaded transmission until the pressing plate 11 conflicts with the hollow floating plate 7.

[0031] 2): After carrying the water level gauge to the use position, release the lock of the pressure plate 11 on the hollow floating plate 7, and install the installation base plate 1 on the river bottom. At this time, the hollow floating plate 7 will be affected by the buoyancy in the water, and under the action of the buoyancy, it will drive the lifting frame 3 to slide upward along the support plate 2.

[0032] 3): The pointer 5 will move relative to the scale bar 6, and then the length of the support plate 2 above the water surface can be read. The length of the support plate 2 minus the reading is the water level.

[0033] To sum up, when the water level gauge of the hydraulic project needs to be used, the rotating frame 9 can be pushed to rotate the rotating shaft 8 until the rotating frame 9 is perpendicular to the mounting base plate 1, and then the threaded column 10 can be rotated to drive the pressure plate 11 to move downward. When the pressure plate 11 moves downward, it will drive the guide rod 13 to slide relative to the rotating frame 9, and the pressure plate 11 can be limited until the pressure plate 11 conflicts with the hollow floating plate 7. The hollow floating plate 7 can be assembled with the mounting base plate 1 to prevent the hollow floating plate 7 from sliding on the outer surface of the support plate 2, which can make it easier to carry the water level gauge. After the water level gauge is carried to the use position, the locking of the hollow floating plate 7 by the pressure plate 11 is released, and the mounting base plate 1 is installed on the river bottom. At this time, the hollow floating plate 7 will be affected by the buoyancy in the water, and the lifting frame 3 will be driven to slide upward along the support plate 2 under the action of the buoyancy. At this time, the pointer 5 will move relative to the scale bar 6, and then the length of the support plate 2 exposed above the water surface can be read. The length of the support plate 2 minus the reading is the water level height, and the support frame 3 can always be located above the water level due to the action of the hollow floating plate 7 floating on the water surface, thereby preventing the scale bar 6 from contacting the river water, and preventing mud and debris from easily adhering to the outer surface of the scale bar 6.
