Description

Technical Field

[0001] This utility model relates to the field of monitoring equipment technology, specifically to a radar water level gauge. Background Technology

[0002] Radar level gauges are advanced water level monitoring devices that employ high-frequency electromagnetic wave ranging technology. They transmit electromagnetic waves towards the liquid surface via sensors and receive the reflected echoes. Combined with signal processing techniques (such as time-of-flight analysis or frequency-modulated continuous wave analysis), they can accurately calculate information such as the distance, azimuth, and height between the liquid surface and the transmission point. Currently, radar level gauges have long-term continuous automatic monitoring capabilities. In water conservancy projects, they can be used for dynamic water level monitoring of rivers, lakes, reservoirs, hydropower stations, and irrigation canals, providing reliable data support for flood control scheduling and water resource management. In municipal engineering, they can be used for water level detection in waterworks, urban sewage networks, and road flooding points, helping to ensure the efficient operation of urban drainage systems and provide early warning of urban flooding. The non-contact measurement characteristics of radar level gauges make them unaffected by water quality and floating debris, while their millimeter-level accuracy significantly improves the reliability of monitoring data, making them core equipment for smart water conservancy and urban infrastructure operation and maintenance.

[0003] In existing technologies, radar level gauges are typically fixed directly to a rigid support frame using bolts or cable ties. While this installation method effectively suppresses displacement and shaking during use, improving measurement stability, it also has significant limitations. Once the equipment is installed and fixed, its spatial orientation (especially its tilt angle) becomes difficult to adjust. Therefore, this application aims to provide a novel radar level gauge that allows for adjustment of its installation angle as needed after it is fixed to the support frame. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by providing a radar level gauge that, after being fixed on a support frame, allows for adjustment of the installation angle according to actual needs.

[0005] The technical solution of this utility model is: a radar water level gauge, including a water level gauge body and a support rod. The water level gauge body is mounted on the support rod through an adjustment mechanism. The adjustment mechanism includes a protective cover, an outer adjustment ring, and an inner adjustment plate. The protective cover is fixedly connected to the support rod. The outer adjustment ring is rotatably mounted inside the protective cover, and the inner adjustment plate is rotatably mounted inside the outer adjustment ring. The rotation axes of the outer adjustment ring and the inner adjustment plate are perpendicular to each other. The lower surface of the water level gauge body is detachably connected to the lower surface of the inner adjustment plate.

[0006] Furthermore, a groove is provided on the lower surface of the adjusting inner plate, and an internal thread is provided on the side wall of the groove.

[0007] Furthermore, the water level gauge body includes a disc-shaped head, a cylindrical middle section, and a conical bottom, with external threads provided on the outer periphery of the head. The internal threads match the external threads, allowing the water level gauge body to be detachably connected to the adjusting inner plate.

[0008] Furthermore, the adjusting outer ring is circular, and two outer ring pivots are symmetrically arranged on the outer side wall of the adjusting outer ring; mounting holes for fixing the pivots are provided on the inner side wall of the protective cover.

[0009] Furthermore, a motor is fixed on the inner top wall of the protective cover, and a drive gear is provided on the output shaft of the motor; a driven gear is provided on one of the outer ring shafts, and the driven gear meshes with the drive gear.

[0010] Furthermore, a telescopic rod is installed inside the protective cover. One end of the telescopic rod is movably connected to the adjusting inner plate through a ball joint, and the other end of the telescopic rod is connected to the inner top wall of the protective cover through a ball joint.

[0011] Furthermore, the connection point between the telescopic rod and the adjusting inner plate is located near the outer ring pivot.

[0012] Furthermore, the telescopic rod can be a pneumatic cylinder, a hydraulic cylinder, or an electric cylinder.

[0013] Furthermore, a groove is provided on the lower surface of the adjusting inner plate, and bolt mounting holes are provided on the side wall of the groove. The water level gauge body can be bolted to the adjusting inner plate through the bolt mounting holes.

[0014] Furthermore, the protective cover and the support rod are connected by bolts or cable ties.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows: The radar water level gauge in this utility model is fixed to the rigid support frame through the adjustment mechanism. After it is fixed, the installation angle of the water level gauge can be easily and accurately adjusted through the adjustment mechanism.

[0021] The present invention will be further described in detail below with reference to specific embodiments. Methods or functional components not specifically described in the embodiments are all prior art. Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. Example

[0022] like Figure 1-4 As shown, this embodiment is a radar level gauge, including a level gauge body 1 and a support rod (not shown). The level gauge body 1 is mounted on the support rod via an adjustment mechanism. The adjustment mechanism includes a protective cover 2, an outer adjustment ring 3, and an inner adjustment plate 4. The protective cover 2 is fixedly connected to the support rod. The outer adjustment ring 3 is rotatably mounted inside the protective cover 2, and the inner adjustment plate 4 is rotatably mounted inside the outer adjustment ring 3. The rotation axes of the outer adjustment ring 3 and the inner adjustment plate 4 are perpendicular to each other. The lower surfaces of the level gauge body 1 and the inner adjustment plate 4 are detachably connected.

[0023] In this embodiment, the adjusting outer ring 3 is circular, and two outer ring rotating shafts 31 are symmetrically arranged on the outer side wall of the adjusting outer ring 3; mounting holes for rotating and fixing the rotating shafts are provided on the inner side wall of the protective cover 2. A groove 41 is provided on the lower surface of the adjusting inner plate 4, and an internal thread is provided on the side wall of the groove 41. The water level gauge body 1 includes a disc-shaped head 11, a cylindrical middle part 12, and a conical bottom 13, and an external thread is provided on the outer periphery of the head 11. The internal thread and the external thread match each other, so that the water level gauge body 1 and the adjusting inner plate 4 can be detachably connected.

[0024] In this embodiment, a motor 5 is fixed on the inner top wall of the protective cover 2, and a driving gear 6 is provided on the output shaft of the motor 5; a driven gear is provided on one of the outer ring rotating shafts 31, and the driven gear meshes with the driving gear 6. A telescopic rod 8 is provided inside the protective cover 2. One end of the telescopic rod 8 is movably connected to the adjusting inner plate 4 through a ball joint seat 9, and the other end of the telescopic rod 8 is connected to the inner top wall of the protective cover 2 through a ball joint seat 9. The connection point (i.e., the ball joint seat) between the telescopic rod 8 and the adjusting inner plate 4 is located near the outer ring rotating shaft 31 and passes through the vertical plane of the line connecting the two outer ring rotating shafts 31.

[0025] In this embodiment, the telescopic rod 8 is an electric cylinder. A flange is welded to the top of the protective cover 2, and the flange is bolted to the support rod. Both the telescopic rod 8 and the motor 5 are connected to the controller via cables. Under the adjustment of the controller (such as a microcontroller), the telescopic rod 8 and the motor 5 work together to precisely adjust the angle of the water level gauge body 1.

[0026] The adjustment principle of the radar water level gauge in this embodiment is as follows: when the motor 5 is working, it drives the active gear 6 to rotate, thereby driving the driven gear 7 to rotate, which in turn causes the outer adjustment ring 3 to deflect; when the telescopic rod 8 extends or retracts, the deflection angle of the inner adjustment plate 4 can be adjusted; therefore, through the coordinated action of the two, the angle of the water level gauge body 1 can be precisely controlled.

[0027] The above are only some embodiments of the present utility model and are not intended to limit the present utility model. For those skilled in the art, the present utility model can have various combinations and modifications of the aforementioned technical features. Any improvements, modifications, equivalent substitutions, or applications of the structure or method of the present utility model to other fields to achieve the same effect without departing from the spirit and scope of the present utility model shall fall within the protection scope of the present utility model.
