Description
Technical Field
[0001] The utility model belongs to the technical field of water level inspection, and particularly relates to a water level gauge for a water collection well of a hydropower station. Background Art
[0002] The seepage water from the dam body is collected into the water collection well of the hydropower station through the drainage ditch. The drainage system starts and stops the drainage pump according to the set water level setting value to pump the water from the water collection well into the tail water of the unit. The wall of the water collection well is equipped with a water level gauge (such as Figure 4 As shown in the figure), maintenance personnel read the current water level value based on this water level gauge. The technical problems encountered at this stage are:
[0003] 1. The oil leaked from each system of the unit is collected in the water collection well, which makes it easy for oil and sediment to adhere to the surface of the scale body, resulting in the obstruction of the scale line or the indicated number, which is easy to cause errors when reading;
[0004] 2. When cleaning the surface, there are great safety risks and it is very inconvenient. Summary of the invention
[0005] The technical problem to be solved by the utility model is to provide a water level gauge for a water collection well of a hydropower station, which solves the problem that the surface of the existing gauge body is easily attached with oil stains and sediments, resulting in obstruction of scale lines or indicating numbers.
[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:
[0007] A water level gauge for a water collection well of a hydropower station comprises a gauge body, a vertical slide groove is arranged on the gauge body, the vertical slide groove is slidably matched with an indicator plate needle, a brush for wiping the surface of the gauge body is installed on the indicator plate needle, and a float is arranged on the indicator plate needle.
[0008] Preferably, a slider is provided on the inner side of the indicator plate needle, and the slider is adapted to the vertical slide groove; the indicator plate needle is located on the front side of the ruler body, and a back plate is provided on the back side of the ruler body, and the back plate and the indicator plate needle are connected to the float through bolts.
[0009] Preferably, the float is located at the end of the indicator plate needle.
[0010] Preferably, the front side of the ruler body is coated with a hydrophobic and oleophobic coating.
[0011] The utility model can achieve the following beneficial effects:
[0012] The invention solves the problem that the existing scale body is easily attached with oil and sediment, resulting in the obstruction of the scale line or the indication number. It can effectively improve the accuracy of water level identification in the water collection well, greatly reduce the maintenance cost of the scale body, and reduce safety risks.

[0018] In the figure: a ruler body 1, a vertical slide 2, an indicator plate needle 3, a brush 4, a float 5, a slider 6, a back plate 7, and a water collection well 8. DETAILED DESCRIPTION
[0019] The preferred solution is Figures 1 to 3 As shown, a water level gauge for a water collection well of a hydropower station comprises a gauge body 1, a vertical slide groove 2 is provided on the gauge body 1, the vertical slide groove 2 is slidably matched with an indicator plate needle 3, a brush 4 for wiping the surface of the gauge body 1 is installed on the indicator plate needle 3, and a float 5 is provided on the indicator plate needle 3. When the water level floats, the float 5 will float along with the water level, and the float 5 will drive the indicator plate needle 3 to float up and down. During the movement of the indicator plate needle 3, the brush 4 will wipe the surface of the gauge body 1, thereby achieving the purpose of cleaning the gauge body 1. In addition, the position of the indicator plate needle 3 can also assist workers to see the position of the water level clearly.
[0020] Specifically, a slider 6 is provided inside the indicator plate needle 3, and the slider 6 is adapted to the vertical slide groove 2; the indicator plate needle 3 is located on the front of the scale body 1, and a back plate 7 is provided on the back of the scale body 1, and the back plate 7 and the indicator plate needle 3 are connected to the float 5 through bolts. The float 5 is located at the end of the indicator plate needle 3. Figure 1 As shown, the float 5 is located on the right side of the indicator plate needle 3, and the vertical slide groove 2 is located on the right side of the scale body 1. The indicator plate needle 3 and the float 5 are slidably mounted on the float 5 as a whole, and the center of gravity of the indicator plate needle 3 and the float 5 is located at the slider 6, which is used to reduce the friction between the slider 6 and the vertical slide groove 2.
[0021] Preferably, the front side of the ruler body 1 is coated with a nano-hydrophobic and oleophobic coating.
[0022] In this embodiment, the scale lines are sprayed at intervals of 0.1m on the ruler body 1, and the scale lines are set with color characteristics horizontally: the half-meter scale is sprayed with black, the whole meter scale is sprayed with red, and the other scales are sprayed with yellow, green, orange, and blue in sequence; the length characteristics are set vertically: the 0.1m starting scale length is 55% of the width of the scale line area of the ruler body, and the lengths of other scales increase by 5% in sequence, and the length of the whole meter scale is 100% of the width of the scale line area of the ruler body. The water level depth mark is sprayed at the half-meter and whole meter longitudinal positions on the right side of the ruler body. After the scale lines and water level depth marks are sprayed, a transparent transition layer is sprayed on the surface, and a nano-hydrophobic and oleophobic coating with excellent wear resistance and corrosion resistance is prepared on the transition layer. The water level scale line can be quickly and accurately located and identified through the lateral characteristics, the longitudinal characteristics, and the longitudinal water level mark.
