Description

Technical Field

[0001] This invention relates to the field of water level gauges, and particularly to an ultrasonic water level gauge that adapts to water surface fluctuations. Background Technology

[0002] An ultrasonic level gauge is a non-contact instrument that uses ultrasonic waves to measure liquid levels. Its core working principle is that an ultrasonic pulse is emitted from the probe towards the liquid surface. After the sound wave is reflected by the liquid surface, it is received by the probe. The instrument calculates the distance from the probe to the liquid surface by accurately calculating the propagation time of the ultrasonic wave in the air and combining this with the speed of sound, thus calculating the actual water level value.

[0003] Currently, in practical applications, existing ultrasonic water level gauges are often affected by external factors such as wind, water flow, ship traffic, or precipitation, which cause significant fluctuations in the water surface. This leads to unstable echo signals received by the instrument, resulting in frequent jumps in water level measurement values ​​with a large instantaneous range. This instability not only interferes with the continuity and readability of the data but also makes it difficult to accurately and reliably monitor the water level in real time, thus limiting the effective application of the device in environments requiring high precision. Summary of the Invention

[0004] The purpose of this invention is to provide an ultrasonic level gauge that adapts to water surface fluctuations, which solves the problem that existing ultrasonic level gauges suffer from frequent fluctuations in measured values ​​and poor stability due to water surface fluctuations, making it difficult to achieve reliable real-time monitoring in high-precision environments.

[0005] To achieve the above-mentioned objectives, the technical solution adopted by this invention is as follows:

[0006] A water level gauge body is located in front of the support device;

[0007] The support device is equipped with a blocking mechanism, which includes a first bracket. The water level gauge body is fixedly installed on the first bracket. A blocking chamber is provided under the first bracket. An isolation chamber is installed and fixed outside the blocking chamber. Several tiny gaps are cut into the isolation chamber.

[0008] The first bracket provides support, facilitating the installation of a mechanism to isolate water surface fluctuations. The blocking chamber provides protection, protecting the water level gauge when it is not in use. It also facilitates the connection of the isolation chambers, effectively dispersing water wave forces and reducing the amplitude of water fluctuations within the isolation chamber.

[0009] The support device is equipped with a drive mechanism, which includes a second bracket connected to the support device. A threaded rod is rotatably installed between the second bracket and the first bracket. The slider is slidably installed on the threaded rod. A pair of slides are fixedly installed between the first bracket and the second bracket.

[0010] The installation of the second bracket facilitates the rotation of the threaded rod, which in turn facilitates the sliding of the slider. This allows the slider to move the isolation chamber downwards or upwards. The slide design also ensures the isolation chamber has a certain degree of stability when rising or falling, making the sliding smoother.

[0011] As an improvement, a lower magnetic suction device is fixedly installed on the isolation chamber, and an upper magnetic suction device is fixedly installed on the lower part of the first bracket.

[0012] The design of the lower and upper magnetic attraction facilitates the attraction between the two, making the isolation chamber more secure when stationary. At the same time, it reduces the force on the slider on the threaded rod, thus extending the service life of the threaded rod.

[0013] As an improvement, the lower magnetic attraction matches the upper magnetic attraction, and a slider is fixedly installed on the isolation chamber.

[0014] The installation of the slider facilitates the association between the isolation chamber and the threaded rod, making it easier for the threaded rod to move the isolation chamber when it rotates.

[0015] As an improvement, a pair of pulleys are slidably mounted on the carriage, and a connecting frame is fixedly mounted on the pulleys. The pair of connecting frames are connected to the isolation chamber.

[0016] The installation of the connecting frame facilitates the connection between the pulley and the isolation chamber, allowing the pulley to slide on the frame when the isolation chamber slides, thus ensuring the stability of the isolation chamber.

[0017] As an improvement, an electric motor is fixedly installed under the first bracket, with one end of the electric motor passing through the first bracket.

[0018] The installation of an electric motor facilitates the conversion of electrical energy into mechanical energy, which in turn drives the rotation of the synchronous pulley on it.

[0019] As an improvement, one end of the threaded rod passes through the first bracket, and synchronous pulleys are respectively installed on the threaded rod and the motor, and a synchronous belt is sleeved between a pair of synchronous pulleys.

[0020] The combination of the synchronous pulley and the synchronous belt allows the threaded rod to rotate synchronously with the motor when it is rotating.

[0021] The beneficial effects of this invention are as follows: by adopting the setting of the blocking mechanism, it can extend into the water surface, thereby isolating the water surface outside the isolation chamber from a small range, keeping the water inside the blocking chamber in a stable state. Therefore, it significantly improves the stability and accuracy of water level measurement data, achieves isolation from external environmental interference, and thus ensures continuous and reliable water level monitoring, expanding the application range of ultrasonic water level gauges in high-precision measurement scenarios.

[0027] To make the content of this invention easier to understand, the technical solutions of the embodiments of this invention will be clearly and completely described below with reference to the accompanying drawings. Identical components are represented by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "inner" and "outer" refer to directions toward or away from the geometric center of a specific component, respectively.

[0028] like Figures 1 to 4As shown, a water level gauge body 101 is provided in front of the support device 1; a blocking mechanism 2 is installed on the support device 1, the blocking mechanism 2 includes a first bracket 201, the water level gauge body 101 is fixedly installed on the first bracket 201, a blocking chamber 202 is provided under the first bracket 201, an isolation chamber 203 is fixedly installed outside the blocking chamber 202, and several small gaps are cut in the isolation chamber 203; a driving mechanism 3 is installed on the support device 1, the driving mechanism 3 includes a second bracket 301, the second bracket 301 is connected to the support device 1, a threaded rod 302 is rotatably installed between the second bracket 301 and the first bracket 201, a slider 206 is slidably installed on the threaded rod 302, and a pair of slides 303 are fixedly installed between the first bracket 201 and the second bracket 301.

[0029] The first bracket 201 provides support and facilitates the installation of a mechanism to isolate water surface fluctuations. The blocking chamber 202 provides protection. When the water level gauge body 101 is not used for monitoring, the blocking chamber 202 can protect the water level gauge body 101. It also facilitates the connection of the isolation chamber 203. The isolation chamber 203 can effectively disperse the water wave force and reduce the amplitude of water fluctuations within the isolation chamber 203.

[0030] In addition, the installation of the second bracket 301 facilitates the rotational installation of the threaded rod 302. The rotation of the threaded rod 302 facilitates the sliding of the slider 206, thereby enabling the slider 206 to drive the isolation chamber 203 to slide downwards or upwards. The design of the slide 303 ensures that the isolation chamber 203 has a certain degree of stability when rising or falling, making the sliding smoother.

[0031] like Figures 2 to 4 As shown, a lower magnetic 204 is fixedly installed on the isolation chamber 203, and an upper magnetic 205 is fixedly installed on the lower part of the first bracket 201.

[0032] Furthermore, the arrangement of the lower magnetic 204 and the upper magnetic 205 facilitates the attraction between the two, thereby making the isolation chamber 203 more secure when stationary. At the same time, it can reduce the force of the slider 206 on the threaded rod 302, thus extending the service life of the threaded rod 302.

[0033] like Figures 2 to 4 As shown, the lower magnetic attraction 204 matches the upper magnetic attraction 205, and a slider 206 is fixedly installed on the isolation chamber 203.

[0034] Secondly, the installation of the slider 206 facilitates the association of the isolation chamber 203 with the threaded rod 302, making it easier for the threaded rod 302 to drive the movement of the isolation chamber 203 when it rotates.

[0035] like Figures 2 to 4 As shown, a pair of pulleys 304 are slidably mounted on the slide 303, and a connecting frame 305 is fixedly mounted on the pulleys 304. The pair of connecting frames 305 are connected to the isolation chamber 203.

[0036] In addition, the installation of the connecting frame 305 facilitates the connection between the pulley 304 and the isolation chamber 203, so that when the isolation chamber 203 slides, the pulley 304 can slide on the slide frame 303, thereby ensuring the stability of the isolation chamber 203.

[0037] like Figures 1 to 4 As shown, a motor 306 is fixedly installed under the first bracket 201, and one end of the motor 306 passes through the first bracket 201.

[0038] The installation of the electric motor 306 facilitates the conversion of electrical energy into mechanical energy, which in turn helps to drive the rotation of the synchronous pulley 307 on it.

[0039] like Figures 1 to 4 As shown, one end of the threaded rod 302 passes through the first bracket 201. Synchronous pulleys 307 are respectively installed on the threaded rod 302 and the motor 306. A synchronous belt 308 is sleeved between the pair of synchronous pulleys 307.

[0040] In addition, the cooperation between the synchronous pulley 307 and the synchronous belt 308 is beneficial to the synchronous rotation of the threaded rod 302 with the motor 306 when the motor 306 is rotating.

[0041] During use, when it is necessary to measure the distance to the water surface through the water level gauge body 101, in order to prevent the water surface from fluctuating significantly and affecting the monitoring of the water level gauge body 101, the electric motor 306 can be used to drive the slider 206 to descend through the cooperation of the synchronous pulley 307 and the synchronous belt 308. The descent of the slider 206 will cause the connecting frame 305 and the pulley 304 to slide on the slide 303, thus ensuring that the isolation chamber 203 descends in a straight and stable manner. During descent, the isolation chamber 203 and the blocking chamber 202 will come into contact with the water surface. Through the special material of the isolation chamber 203 and the tiny gaps drilled on it, the wave force of the water surface can be buffered to a certain extent. At the same time, through the isolation of the isolation chamber 203, it can be ensured that the wave force of the water inside the isolation chamber 203 is less than the wave force outside the isolation chamber 203, so that the water surface can be measured more conveniently and accurately through the water level gauge body 101.

[0042] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the present invention.
