Description

Technical Field

[0001] The utility model relates to the technical field of water level measurement, in particular to a reservoir water level measuring device. Background Art

[0002] A reservoir generally refers to a hydraulic engineering structure used to intercept floods, store water and regulate water flow. It can be used for irrigation, power generation, flood control and fish farming. A reservoir is generally an artificial lake formed by building a dam at the narrow mouth of a ravine or river. The water level of the reservoir needs to be tested during daily maintenance.

[0003] Chinese Patent Publication No.: CN 215114759 U, a reservoir water level measuring device, by setting an electric telescopic block, a limit groove and a limit block, the reservoir water level measuring device can release the electric telescopic block when in use, so that it will not be affected by the waves generated by wind, and the accuracy of water level measurement will not be affected by these waves, so as not to cause the operator to misjudge the water level. However, its electric telescopic block can only prevent the waves near the water surface from affecting the measuring line. The surging water flow under the water surface will cause a large deviation of the measuring line, resulting in a significant decrease in measurement accuracy. Utility Model Content

[0025] The embodiments of the present application solve the problems in the prior art by providing a reservoir water level measuring device.

[0026] The technical solution in the embodiment of the present application is to solve the above problems, and the overall idea is as follows:

[0027] Embodiment 1:

[0028] The specific structure of this embodiment is as follows: Figure 1-Figure 4 As shown, a reservoir water level measuring device comprises:

[0029] Hollow rod 1 and motor 2 13, one side of the hollow rod 1 is fixedly connected with motor 1 2, the output end of motor 1 2 is fixedly connected with propeller 3, the other side of the hollow rod 1 is fixedly connected with fixing frame 4, the middle part of fixing frame 4 is fixedly connected with current meter 5, one side of current meter 5 is fixedly connected with signal line 6, one end of signal line 6 away from current meter 5 is fixedly connected with the side of motor 1 2, and one side of the hollow rod 1 away from current meter 5 is fixedly connected with guide plate 8;

[0030] The top cover 11 has a screw 12 fixedly connected to its bottom, the screw 12 is threadedly connected to an opening on the inner wall of the hollow rod 1 , and the bottom of the top cover 11 fits the top of the hollow rod 1 .

[0031] In some examples, the output shaft end of the motor 2 13 is fixedly connected to a winding shaft 14 , a measuring line 15 is wound around the surface of the winding shaft 14 , and a lower end of the measuring line 15 is fixedly connected to the top of the top cover 11 .

[0032] In some examples, the bottom of the base of the second motor 13 is fixedly connected to a fixing frame 16 , and the side of the winding shaft 14 away from the second motor 13 is rotatably connected to the side wall of the fixing frame 16 through a rotating shaft and a bearing.

[0033] In some examples, a connecting rod 17 is fixedly connected to one side of the fixed frame 4 away from the hollow rod 1, and a protective shell 18 is fixedly connected to one end of the connecting rod 17 away from the fixed frame 4. A through hole 19 is opened on the surface of the protective shell 18, and the flow meter 5 is located inside the protective shell 18.

[0034] In some examples, a protective shell 20 is fixedly connected to one side of the hollow rod 1 away from the fixed frame 4, a protective plate 21 is fixedly connected to the opening of the protective shell 20, and the motor 1 2 and the propeller 3 are located inside the protective shell 20.

[0035] In some examples, a protective tube 7 is fixedly connected to the surface of the hollow rod 1, the signal line 6 is located inside the protective tube 7, and both sides of the protective tube 7 are fixedly connected to the side surfaces of the protective shell 1 18 and the protective shell 2 20 respectively.

[0036] By adopting the above technical solution:

[0037] Place the fixing frame 16 on the bank of the reservoir or on the measuring ship, pour fine sand into the hollow rod 1 to increase the weight of the hollow rod 1, then install the top cover 11 to the top opening of the hollow rod 1 through the screw 12, and then turn on the motor 2 13 to drive the winding shaft 14 to rotate, remove the measuring line 15 from the winding shaft 14, and make the hollow rod 1 gradually sink into the water. The guide plate 8 plays a guiding role. When the water flow under the water surface washes the hollow rod 1, the guide plate 8 allows the current meter 5 to face the water flow, so that the propeller 3 is at the lower water level. The protective shell 18 protects the internal current meter 5. The water flows into the protective shell 18 through the through hole 19 and contacts the current meter 5. The current meter 5 is sensitive to the water flow. The speed is detected and a signal is sent to the motor 2 through the signal line 6, the motor 2 is turned on to drive the propeller 3 to rotate. When the water flow velocity detected by the current meter 5 is faster, the propeller 3 rotates faster and the direction in which the propeller 3 pushes the water flow is the same as the direction of the water flow under the water surface, so that the hollow rod 1 can resist the interference of the water flow and remain in a vertical state and is always located directly below the water entry point, thereby avoiding the measurement line 15 from deviating underwater and causing a decrease in measurement accuracy. Increasing the weight of the hollow rod 1 by adding fine sand can also improve the stability of the hollow rod 1 and reduce the deviation of the hollow rod 1, thereby solving the problem that the surging water flow below the water surface will cause a large deviation of the measurement line, thereby greatly reducing the measurement accuracy.

[0038] Embodiment 2:

[0039] The specific structure of this embodiment is as follows: Figure 1-Figure 2 As shown, a bottom plate 9 is fixedly connected to the bottom of the hollow rod 1, and an insertion rod 10 is fixedly connected to the bottom of the bottom plate 9. The insertion rod 10 is conical in shape.

[0040] By adopting the above technical solution:

[0041] As the hollow rod 1 continues to move downward, the bottom of the bottom plate 9 contacts the bottom of the reservoir, and the inserted rod 10 is inserted into the mud at the bottom of the reservoir to improve stability. The bottom plate 9 plays a supporting role on the mud to prevent the hollow rod 1 from sinking into the mud. At this time, the water level in the reservoir is observed through the measuring line 15.

[0042] The above only describes some exemplary embodiments of the present invention by way of illustration. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
