Description

Technical Field

[0002] The dam water level monitoring device refers to a device installed near the dam, used to detect the dam water level and regularly record and feedback. It is one of the important components of the dam system. The dam water level monitoring device can assist observers in judging the information of the dam and speed up the feedback speed of the dam system for adjustment. The existing dam water level monitoring device usually detects the water level height through ultrasonic sensors. However, in some windy and wave environments, the water surface will have large fluctuations. The ultrasonic sensor is easily affected by the undulating water surface, and the measured data will have large fluctuations.

[0003] Therefore, a new solution needs to be proposed to solve this problem. Utility Model Content

[0010] The utility model is further configured as follows: the two clamps are connected by fastening bolts, and the fastening bolts penetrate the two clamps along the vertical direction.

[0011] To sum up, the utility model has the following beneficial effects: the sleeve isolates the external waves and avoids the interference of the water surface fluctuations in the sleeve to the sensor; the cover plate shields the top surface of the sleeve and avoids the entry of debris into the sleeve from the top surface of the sleeve, thereby reducing the interference to the sensor and improving the monitoring accuracy of the sensor, thereby improving the effect of water conservancy management; an opening is provided at the top of the side wall of the sleeve, and the opening ensures that the gas inside the sleeve can be discharged, thereby ensuring that the water level in the sleeve is consistent with the outside world.

[0015] The utility model is described in detail below in conjunction with the accompanying drawings and embodiments.

[0016] Embodiment: A dam water level monitoring device, such as Figure 1 , Figure 2 As shown, it includes a column 1 and a sensor 2 located at the top of the column 1. A sleeve 3 is provided on one side of the column 1. The bottom surface of the sleeve 3 is lower than the bottom surface of the column 1. The sensor 2 is located at the top of the inner cavity of the sleeve 3, and the sensor 2 is located on the axis of the sleeve 3.

[0017] Specifically, the sensor 2 confirms the water level through ultrasound, the column 1 is fixedly connected to the shore, the bottom end of the sleeve 3 is immersed in the water, and the diameter of the sleeve 3 is larger than the diameter of the column 1. Because the bottom end of the sleeve 3 is connected to the water body below, the water level in the sleeve 3 rises synchronously with the water level of the water body, and the sleeve 3 isolates the external waves, avoiding the interference of the water surface fluctuations in the sleeve 3 to the sensor 2, thereby improving the monitoring accuracy of the sensor 2, and thus improving the effect of water conservancy management, and the sensor 2 is located on the axis of the sleeve 3, reducing the influence of the inner wall of the sleeve 3 on the sensor 2.

[0018] like Figure 1 , Figure 2 As shown, the sensor 2 is connected to the column 1 through a connecting rod 4, the connecting rod 4 passes through the side wall of the sleeve 3, and a cover plate 5 is detachably connected to the top surface of the sleeve 3. The top surface of the connecting rod 4 and the top surface of the sensor 2 are both in contact with the bottom surface of the cover plate 5, and a filter screen 6 is fixedly connected to the bottom surface of the sleeve 3.

[0019] Specifically, the connecting rod 4 is perpendicular to the column 1, and the top surface of the connecting rod 4 is flush with the top surface of the column 1. The diameter of the cover plate 5 is larger than the diameter of the sleeve 3. The cover plate 5 is connected to the sleeve 3 by bolts. The cover plate 5 shields the top surface of the sleeve 3 to prevent debris from entering the sleeve 3 from the top surface of the sleeve 3, thereby reducing the interference to the sensor 2. An opening is provided at the top of the side wall of the sleeve 3, and the opening ensures that the gas inside the sleeve 3 can be discharged, ensuring that the water level in the sleeve 3 is consistent with the outside world. The filter screen 6 is integrally formed with the sleeve 3, and the filter screen 6 prevents debris from entering the interior of the sleeve 3 from the bottom end of the sleeve 3, thereby further reducing the interference to the sensor 2.

[0020] like Figure 1 , Figure 2 As shown, a connecting piece is sleeved on the column 1, and the other end of the connecting piece is sleeved outside the sleeve 3. The connecting piece is composed of two clamps 7. Any clamp 7 is located on the same side of the column 1 and the sleeve 3. The two clamps 7 are connected by a fastening bolt 8, and the fastening bolt 8 passes through the two clamps 7 along the vertical direction.

[0021] Specifically, two clamps 7 are combined to form an 8-shaped connecting piece. The clamp 7 locks the angle between the column 1 and the sleeve 3 to prevent the sleeve 3 from tilting and interfering with the sensor 2. The two clamps 7 are respectively located on both sides of the sleeve 3 to facilitate disassembly and assembly of the clamp 7. The force direction of the fastening bolt 8 is perpendicular to the length direction of the fastening bolt 8 to prevent the fastening bolt 8 from loosening.

[0022] The above is only a preferred embodiment of the present invention. The protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
