[0024] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0025] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application pertains. The terms used herein in the specification of this application are for the purpose of describing specific embodiments only and are not intended to limit this application.

[0026] Combine Figure 1-4 As shown, a self-cleaning water level measuring instrument includes:

[0027] The measuring instrument body 1 adopts the existing AI intelligent water level monitoring equipment, such as the detection equipment with model number YLN-RS-230, which has a camera at the bottom and a slide groove 11 vertically arranged on its shell;

[0028] The connecting seat 2 is movably mounted on the slide 11, and its main body is set to be rectangular, and a hinge seat 21 is provided at the end, and is movably connected to the mounting plate 3 cleaning assembly 4 through the hinge seat 21;

[0029] The cleaning component 4 is arranged on the end surface of the mounting plate 3, and the mounting plate 3 is deflected toward the camera direction, so that the cleaning component 4 can fit with the surface of the camera.

[0030] Specifically, in this embodiment, the camera adopts a transparent shell 14, that is, a glass cover to cover it, so that the bottom forms a hemispherical structure, the purpose of which is to improve the protection effect of the camera to prevent damage due to external impact.

[0031] Since this type of detection equipment is usually set up by the water through a bracket, it is extremely susceptible to the influence of fog. In particular, when the water fog adheres to the outer wall of the transparent shell 14, it will cover the camera and make it impossible to measure. Therefore, a heater 5 should also be provided on the bottom surface of the measuring instrument body 1. The heater 5 can be an electric heating wire or a thinner electric heating tube, and it should be installed between the transparent shell 14 and the camera, so that the temperature inside the cavity between the two is quickly increased, so that the fog on the surface of the transparent shell 14 is quickly dried.

[0032] However, in actual use, in addition to water mist, this transparent shell 14 is also easily affected by dust. After the dust adheres to the outer wall of the transparent shell 14, it affects the function of laser ranging, thereby causing inaccurate measurement data. Therefore, in this embodiment, additional equipment that can be cleaned regularly, namely, a cleaning component 4, should be arranged.

[0033] The cleaning assembly 4 includes a cleaning plate 41, a connecting shaft 42 and a motor B43, wherein the cleaning plate 41 is configured as an arc-shaped plate, and a hemispherical arc groove is provided on the end face of the mounting plate 3. The arc plate is fitted inside the arc groove, and a connecting shaft 42 is provided on the top. The motor B43 is directly arranged inside the mounting plate 3, and the connecting shaft 42 extends toward the inside of the mounting plate 3 and is transmission-connected to the output end of the motor B43.

[0034] A plurality of bristles are arranged on the inner wall of one end of the cleaning plate 41 away from the connecting shaft 42. Driven by the motor B43, these bristles can be attached to the transparent shell 14 for rapid cleaning.

[0035] Taking into account that dust cannot be effectively removed by wiping alone during actual use, in this embodiment, the connecting shaft 42 and the cleaning plate 41 should both be set to a hollow structure and connected to each other. At the same time, a number of fine holes are provided on the end face of the cleaning plate 41. These fine holes are arranged in an interlaced manner with the brush, so that the brush can be used in combination with water injection for cleaning, which can effectively remove dust and dirt on the transparent shell 14 and greatly improve the cleaning effect.

[0036] During the water injection process, since the connecting shaft 42 needs to rotate, a connecting sleeve 44 should also be provided on the connecting shaft 42. The ports at both ends of the connecting sleeve 44 use ball bearings to movably connect with the connecting shaft 42. One side is also fixedly connected to the inside of the mounting plate 3, and sealing gaskets are used at both ends of the ball bearings for sealing. At the same time, a water pipe 45 is provided on the outer wall of the connecting sleeve 44. The water pipe 45 extends inward and is connected to the cavity formed between the inner wall of the connecting sleeve 44 and the outer wall of the connecting shaft 42, and passes outward to the outer wall of the mounting plate 3 and is connected to the water storage container.

[0037] In addition, a solenoid valve 46 should be set at the connection between the water pipe 45 and the connecting sleeve 44, and a through hole should be provided on the outer wall of the connecting shaft 42. The through hole should be located exactly in the middle of the range covered by the connecting sleeve 44. In this way, the water injected between the connecting sleeve 44 and the connecting shaft 42 can be input into the pores through the through hole, thereby achieving the purpose of cleaning. In this process, the cleaning plate 41 can also be kept in a rotating state.

[0038] In addition, the cleaning structure also needs to be equipped with an adjustment function so that it can be moved to one side when not cleaning to avoid affecting normal water level detection.

[0039] Based on the above requirements, in this embodiment, a plug shaft 22 should be provided on the hinge seat 21 of the connecting seat 2, a motor A23 is provided at one end of the plug shaft 22, and the side wall of the motor A23 should be fixedly connected to the side wall of the connecting seat 2, and the output end of the motor A23 should be transmission-connected to the end of the plug shaft 22, and a hinge joint should be provided on the mounting plate 3, and the hinge joint should be movably connected to the plug shaft 22. In addition, a limiting structure should be provided between the two, for example Figure 1 As shown, the top surface of the connecting base 2 is partially extended so that the mounting plate 3 can only be deflected by 90° toward the camera.

[0040] When the structure is rotated to a vertical state, it should also be retracted to be flush with the measuring instrument body 1 so that the side wall of the mounting plate 3 fits in with the side wall of the measuring instrument body 1 to prevent the bristles on the side wall of the mounting plate 3 from being contaminated with too much dust, which would affect the cleaning effect next time.

[0041] Therefore, a drive shaft 12 should be set inside the slide groove 11 on the side wall of the measuring instrument body 1. The drive shaft 12 adopts a screw structure. A protrusion is provided at the bottom of the connecting seat 2 and is inserted into the slide groove 11. The screw penetrates the side wall of the protrusion along the direction of the slide groove 11 and is threadedly assembled with it. Therefore, when the screw rotates, it will force the connecting seat 2 to move up and down along the direction of the slide groove 11. A servo motor 13 is equipped inside the measuring instrument body 1 to control the transmission direction of the screw.

[0042] In the above structure, the liquid storage chamber that needs to supply water to the water pipe 45 can be arranged inside the connecting seat 2, or a separate box for storing cleaning liquid can be set outside. The cleaning liquid can not only be water, but also other cleaning agents with volatile effects.

[0043] If water and a brush are used for cleaning, the heater 5 should be used for heating during the cleaning process to avoid a large amount of moisture remaining on the surface of the transparent shell 14 after cleaning, causing dust in the air to be adsorbed on the surface again. At the same time, the brush can also be heated and dried to prevent it from being contaminated with too much dust.

[0044] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit it. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the technical solutions of the embodiments of the present invention.
