Description

Technical Field

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

[0002] At present, the way hydropower stations observe water depth is to fix the water gauge on the surface of a long metal pipe or wooden strip, insert it vertically into the water body and fix it, so that observers can read the water gauge directly according to the water surface height. However, the facilities are outdated, the observation accuracy is not high, and there are relatively few measuring points. Often, only one observation point is set to observe the water level of the reservoir. It is impossible to avoid various errors caused by the upstream and downstream of the reservoir and wind and waves. At the same time, the observation and data collection and transmission methods are generally backward. The existing radar water level meter is installed on one side of the building. The measurement accuracy is greatly affected by the wind and waves on the water surface, and the error can even reach the centimeter level.

[0003] The above reasons lead to large errors in reservoir water level measurement, which in turn causes large errors in reservoir capacity. The capacity error of large reservoirs can even reach hundreds of thousands of cubic meters. The accuracy and timeliness of the data cannot meet the needs of flood control scheduling during the reservoir flood season. Utility Model Content

It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0027] The specific implementation of the present utility model is described in detail below in conjunction with specific embodiments.

[0028] like Figure 1-Figure 4 As shown, a structural diagram of a reservoir water level measuring device based on a rangefinder provided by an embodiment of the utility model includes a building 1, an iron plate, an outer protective shell 3, a rangefinder 6, an inner protective shell 7 and a floating boat 9, wherein the iron plate is fixedly installed on the side of the building 1, and a GNSS receiver 2, a water pump 4 and a processor 5 are arranged on the iron plate, and the processor 5 is connected to a remote computer through a cable; the outer protective shell 3 is fixed to the building 1 by expansion screws, and the outer protective shell 3 is at the bottom of the iron plate; the rangefinder 6 is installed on the top of the outer protective shell 3; the inner protective shell 7 is arranged inside the outer protective shell 3, and a spiral water pipe 8 is arranged in the inner protective shell 7, and the top end of the spiral water pipe 8 is connected to the water pump 4; the floating boat 9 is arranged in the spiral water pipe 8, and a prism is installed on the floating boat 9, and the floating boat 9 moves freely up and down with the water flow in the inner protective shell 7.

[0029] The present application provides a device for measuring reservoir water level based on a rangefinder, which is not only more convenient to operate, but also a floating boat 9 with a prism is arranged in an outer protective shell 3 and an inner protective shell 7, which can reduce the impact of wind and waves on the prism. The prism is also matched with a rangefinder 6 to improve the measurement accuracy, so that the accuracy reaches the millimeter level, and the heat dissipation components are used to reduce the internal temperature and improve the measurement accuracy. The existing GNSS system base points in the reservoir area are used to provide coordinates for the satellite, so as to obtain the elevation at the rangefinder 6, and then obtain the reservoir water level value.

[0030] In an example of the present invention, the processor 5 is powered by solar energy or city electricity. In actual application, an LED display screen may be additionally arranged around the processor 5 to display the current water level in real time.

[0031] like Figure 2 As shown, as a preferred embodiment of the present invention, a screen 10 is provided at the bottom of the inner protective shell 7 .

[0032] In one embodiment of the present invention, by providing the screen 10, insect and rain protection can be performed during the water level measurement process.

[0033] like Figure 2 As shown, as another preferred embodiment of the present invention, the space between the outer protective shell 3 and the inner protective shell 7 is filled with foam.

[0034] In one example of the present invention, by filling with foam, it is possible to prevent water from transferring temperature through the outer protective shell 3 and the inner protective shell 7, thereby achieving the effects of heat insulation and heat preservation.

[0035] like Figure 2 and Figure 3 As shown, as another preferred embodiment of the present utility model, a scoop net is also provided in the inner protective shell 7.

[0036] In one embodiment of the present invention, after the pontoon 9 has been used for a period of time, in order to ensure the accuracy of the pontoon 9 and the prism installed thereon, it is necessary to pull the dredging net and take out the pontoon 9 regularly for cleaning.

[0037] like Figure 2 As shown, as another preferred embodiment of the utility model, a plurality of thermometers are installed along the height direction on the inner side of the inner protective shell 7 , and the thermometers are electrically connected to the water pump 4 .

[0038] In an example of the present invention, a plurality of thermometers monitor the temperature of liquid at different heights in real time, and determine whether it is necessary to pump water for cooling according to the temperature.

[0039] In addition, if the water pump 4 is replaced by a compressor in a refrigerator, the spiral water pipe 8 is replaced by a closed pipe, and the heat transfer medium is replaced by refrigerant instead of water, the heat can be further reduced.

[0040] In summary, the installation of the device is completed according to the diagram. Before use, the processor 5 is remotely operated by the computer to start pumping water. The water with a reservoir water level of 2 meters or even deeper rises along the spiral water pipe 8 to the pump 4 on the top of the outer protective shell 3 under the action of suction, completing the heat absorption of the air in the inner protective shell 7, lowering the internal temperature, and maintaining it for 15-20 minutes; remote control, stop pumping, let it stand for 1-2 minutes, and the remote control rangefinder 6 starts to measure the distance from the prism on the floating boat 9 to the rangefinder 6. The processor 5 integrates the position information provided by the GNSS receiver 2, the measured value of the rangefinder 6 and the draft depth (fixed value) of the floating boat 9, and finally obtains an accurate reading of the reservoir water level, or returns it to the duty personnel computer through the communication cable.

[0041] It is obvious to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the present invention can be implemented in other specific forms without departing from the spirit or basic features of the present invention. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive, and the scope of the present invention is defined by the appended claims rather than the above description, and it is intended that all changes falling within the meaning and scope of the equivalent elements of the claims are included in the present invention.

This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole.
