Description
Technical Field
[0001] The utility model relates to the field of water conservancy projects, in particular to a water level scale for water conservancy projects. Background Technique
[0002] In the field of water conservancy projects, the water level scale rod is one of the most basic and crucial monitoring tools. Whether it is a large reservoir, a hydropower station, or the levees of small and medium-sized rivers, the water level scale is an important reference for judging the safety status of water bodies. By regularly observing the scale lines on the water level scale, water conservancy staff can quickly grasp the water level dynamics, timely adjust the water storage and discharge strategies of the reservoir, ensure the safe operation of the reservoir, and at the same time effectively regulate the flow of the downstream river channel to reduce the occurrence of flood disasters. However, the water level scale rod can only display the current water level and cannot display the highest water level during the measurement period. Content of the Utility Model
[0003] The purpose of the utility model is to provide a water level scale for water conservancy projects to solve the problems put forward in the above background technique.
[0004] To achieve the above purpose, the utility model provides the following technical solutions:
[0005] A water level scale for water conservancy projects includes a measuring scale, a fixed base, scale graduations, a lifting sliding cavity, a lifting float, a highest water level line lifting ruler, an L-shaped water inlet pipe, a one-way water inlet valve, and an electromagnetic drain valve. The fixed base is installed at the bottom of the measuring scale, the scale graduations are installed on the side of the measuring scale, the lifting sliding cavity is opened inside the measuring scale, the lifting float is installed inside the lifting sliding cavity, the highest water level line lifting ruler is installed on the top of the lifting float, and the top of the highest water level lifting ruler passes through the top of the measuring scale. The L-shaped water inlet pipe is opened inside the left side of the fixed base, and the top of the L-shaped water inlet pipe is communicated with the bottom of the lifting sliding cavity. The one-way water inlet valve is installed on the L-shaped water inlet pipe. The electromagnetic drain valve is installed on the lower right side of the lifting sliding cavity, and the water source in the lifting sliding cavity is released through the electromagnetic drain valve to clear the record of the previous highest water level.
[0006] Preferably, the side surface of the highest water level line lifting ruler is also marked with scale graduations, and the scale graduations on the side of the highest water level line lifting ruler gradually increase from top to bottom, and the maximum degree of the part exposed above the top of the measuring scale at the top is used to record the highest water level after the electromagnetic drain valve is closed.
[0007] The beneficial effect of the utility model is that the utility model is reasonably designed and can display the real-time water level through the scale graduations externally, and at the same time can also display the highest water level line during the measurement period by driving the lifting ruler through the lifting of the built-in float.

[0011] The following further elaborates on the present utility model in conjunction with the accompanying drawings and specific embodiments:
[0012] As Figure 1 - Figure 2 shown, a water level scale for a water conservancy project includes a measuring scale 1, a fixed base 2, scale markings 3, a lifting sliding cavity 4, a lifting float 5, a highest water level lifting ruler 6, an L-shaped water inlet pipe 7, a one-way water inlet valve 8, and an electromagnetic drain valve 9. The fixed base 2 is installed at the bottom of the measuring scale 1, the scale markings 3 are installed on the side of the measuring scale 1, the lifting sliding cavity 4 is opened inside the measuring scale 1, the lifting float 5 is installed inside the lifting sliding cavity 4, the highest water level lifting ruler 6 is installed at the top of the lifting float 5, and the top of the highest water level lifting ruler 6 passes through the top of the measuring scale 1. The L-shaped water inlet pipe 7 is opened inside the left side of the fixed base 1, and the top of the L-shaped water inlet pipe 7 is communicated with the bottom of the lifting sliding cavity 4. The one-way water inlet valve 8 is installed on the L-shaped water inlet pipe 7. The electromagnetic drain valve 9 is installed on the lower right side of the lifting sliding cavity 4, and the water source inside the lifting sliding cavity 4 is released through the electromagnetic drain valve 9 to clear the record of the previous highest water level. The side surface of the highest water level lifting ruler 6 is also marked with scale markings, and the scale markings on the side of the highest water level lifting ruler 6 gradually increase from top to bottom, and the maximum degree of the part exposed above the top of the measuring scale 1 at the top is used to record the highest water level after the electromagnetic drain valve 9 is closed.
[0013] Usage method of the present utility model: Install the measuring scale 1 in the water area to be measured through the fixed base 2, and observe the water level in real time through the scale markings 3 on the side. The L-shaped water inlet pipe 7 on the side of the fixed base 2 injects water of the same height as the water surface into the lifting sliding cavity 4 inside the measuring scale 1 through the one-way water inlet valve 8. And after the water level drops, the one-way water inlet valve 8 prevents the water source inside the lifting sliding cavity 4 from flowing out, always maintaining the highest water level. And the lifting float 5 inside the lifting sliding cavity 4 drives the highest water level lifting ruler 6 to pop out, and the maximum degree of the part exposed above the top of the measuring scale 1 at the top is the highest water level after the electromagnetic drain valve 9 is closed.
