Description

Technical Field

[0001] This utility model relates to the field of hydrological detection technology, specifically a remote sensing terminal for river water levels. Background Technology

[0002] Radar level gauges are electronic devices that use electromagnetic waves to detect targets. They emit electromagnetic waves to illuminate the target and receive its echo, thereby obtaining information such as the distance from the water level and water flow to the electromagnetic wave emission point, the rate of change of distance (radial velocity), azimuth, and height.

[0003] Radar level gauges require a support frame to be installed above the river channel during operation. Existing support frames can be referenced from the structure of a remote sensing water level monitoring device (application publication number CN112161671A). This device uses an extension rod to erect the remote sensing equipment above the water surface for remote sensing observation. During operation, the detection direction of the remote sensing device needs to be as perpendicular as possible to the water surface to ensure the accuracy of the detection results. However, due to the complex terrain of the riverbank (such as a large angle between the ground and the water surface), the operator needs to manually adjust the angle of the radar level gauge during installation. The structure of the extension rod above the river channel makes adjusting the radar level gauge too difficult and poses a risk of the operator falling into the river. Utility Model Content

[0004] The technical problem to be solved by this utility model is to provide a river water level telemetry terminal, which has an adjustment structure on its extension rod, allowing the operator to adjust the angle of the radar water level gauge from the side away from the river, reducing the difficulty of debugging and preventing the operator from falling into the river.

[0005] To solve the above problems, the technical solution adopted by this utility model is as follows:

[0006] A water level telemetry terminal, comprising:

[0007] The mounting base includes a bearing portion and a mounting plate fixed to the outer ring of the bearing portion by a connecting rod, and a radar level gauge is provided on the mounting plate.

[0008] An extension assembly includes an extension rod that passes through a support frame, a pressure sleeve that is slidably disposed on the extension rod, a pressure cap that is threadedly connected to one end of the extension rod, and a rotating shaft disposed on the pressure cap; two annular retaining rings are disposed on the extension rod near its two ends, the inner ring of the bearing portion is sleeved on the outer side of one end of the retaining ring, and the pressure sleeve is located between the bearing portion and the pressure cap, and corresponds to the outer ring of the bearing portion;

[0009] The rotating shaft passes through the inside of the extension rod and protrudes to the other end of the extension rod. Rotating the rotating shaft causes the pressure cap to rotate, thereby driving the pressure sleeve to press and fix the outer ring of the bearing portion onto the retaining ring to restrict the rotation of the mounting plate.

[0010] As a further improvement of this utility model, a stop cap is provided on the other end of the extension rod, and a key portion of the rotating shaft is provided on the free end of the rotating shaft. A stop key hole is opened on the stop cap corresponding to the key portion of the rotating shaft. After the pressure cap is rotated into place, the stop cap is installed so that the stop cap is connected to the key portion of the rotating shaft, and the stop cap is fixed to lock the pressure cap.

[0011] As a further improvement of this utility model, the end of the key portion of the rotating shaft is provided with a threaded portion of the rotating shaft. The threaded portion of the rotating shaft passes through the stop key hole and is threadedly connected to a clamping nut. Tightening the clamping nut will press and fix the stop cap on the end of the extension rod.

[0012] As a further improvement of this utility model, the stop cap is provided with a flange, and the flange is provided with end face tooth structures evenly distributed. The retaining ring is provided with end face tooth structures corresponding to the flange. Tightening the clamping nut makes the two end face tooth structures mesh to fix the stop cap on the extension rod.

[0013] As a further improvement of this utility model, the outer side of the stop cap is provided with several flat portions spaced apart, which are used to restrict the rotation of the stop cap when the clamping nut is tightened.

[0014] As a further improvement of this utility model, the extension rod is provided with an optical shaft, a key, and a threaded part in sequence on one end corresponding to the mounting base, and the inner ring of the bearing part is sleeved on the optical shaft; the pressure sleeve is provided with a key hole corresponding to the key, and the pressure sleeve is slidably disposed on the key through the key hole; a pressure cap threaded hole is provided on one side of the pressure cap, and the pressure cap is threadedly connected to the threaded part through the pressure cap threaded hole.

[0015] As a further improvement of this utility model, the pressure sleeve is made of copper, and copper friction rings are provided on both sides of the outer ring of the bearing portion. The friction rings abut against the pressure sleeve to increase friction.

[0016] As a further improvement of this utility model, a support bushing is provided inside the extension rod corresponding to one end of the stop cap, and the support bushing is sleeved on the rotating shaft to support the rotating shaft.

[0017] The beneficial effects of adopting the above technical solution are as follows:

[0018] This utility model's radar level gauge is mounted on an extension rod via a mounting base, and the mounting base is tightened and fixed by rotating a pressure cap, placing the radar level gauge above the river channel. The mounting base includes a bearing part rotatably connected to the extension rod. When the pressure cap is loosened, the radar level gauge rotates under its own weight, causing the bearing part to rotate until the radar level gauge rotates to the position closest to the river surface, making the angle between the radar level gauge's detection direction and the water surface nearly perpendicular. When the support frame cannot be perpendicular to the river surface due to terrain influences, the step of manually adjusting the radar level gauge can be eliminated, improving installation efficiency. Simply wait for the radar level gauge to automatically rotate to the suspended state and then tighten the pressure cap. Furthermore, the tightening of the pressure cap can be performed on the side of the support frame closest to the ground via the rotating shaft structure, eliminating the need for an operator to reach into the river channel for adjustment, thus increasing safety.

[0035] To make the objectives, technical solutions and advantages of this utility model clearer, the utility model will be clearly and completely described below in conjunction with specific embodiments.

[0036] like Figure 1 The diagram shows a river water level telemetry terminal, which includes an extension component 200 and a mounting base 300 rotatably mounted on the extension component 200. When the mounting base 300 is in a suspended state, the pressure cap 204 of the extension component is rotated, causing the pressure cap 204 to drive the pressure sleeve 203 to slide and press against the outer ring of the bearing portion 301 of the mounting base 300, thereby fixing the mounting base 300. The rotation of the pressure cap 204 is transferred to the end of the extension component 200 near the ground through the structure of the rotating shaft 205, which increases the safety of operation. In addition, the automatic suspension design of the mounting base 300 ensures that the detection direction of the radar water level gauge 400 is as perpendicular to the water surface as possible, avoiding the need for repeated adjustments to the angle of the radar water level gauge 400.

[0037] Specifically, see Figures 1 to 5 The mounting base 300 includes a bearing portion 301 and a mounting plate 303 fixed to the outer ring of the bearing portion 301 via a connecting rod 302. A radar level gauge 400 is mounted on the mounting plate 303.

[0038] The extension assembly 200 includes an extension rod 201 that passes through the support frame 100, a pressure sleeve 203 that is slidably disposed on the extension rod 201, a pressure cap 204 that is threadedly connected to one end of the extension rod 201, and a rotating shaft 205 disposed on the pressure cap 204. Two annular retaining rings 202 are disposed near both ends of the extension rod 201. The inner ring of the bearing portion 301 is fitted onto the outer side of one end of the retaining ring 202. The pressure sleeve 203 is located between the bearing portion 301 and the pressure cap 204, and corresponds to the outer ring of the bearing portion 301. The rotating shaft 205 passes through the interior of the extension rod 201 and protrudes to the other end of the extension rod 201. Rotating the rotating shaft 205 causes the pressure cap 204 to rotate, thereby driving the pressure sleeve 203 to press and fix the outer ring of the bearing portion 301 onto the retaining rings 202 to restrict the rotation of the mounting plate 303.

[0039] See Figure 5A stop cap 206 is provided on the other end of the shaft 201. A shaft key 205-1 is provided on the free end of the shaft 205. A stop key hole 206-3 is provided on the stop cap 206 corresponding to the shaft key 205-1. After the pressure cap 204 is rotated into position, the stop cap 206 is installed, so that the stop cap 206 is keyed to the shaft 205, fixing the stop cap 206 to lock the pressure cap 204. The end of the shaft key 205-1 is provided with a shaft thread 205-2, which is combined with... Figure 3 The threaded part 205-2 passes through the stop key hole 206-3 and is threadedly connected to a clamping nut 207. Tightening the clamping nut 207 clamps the stop cap 206 onto the end of the extension rod 201. Alternatively, the pivot key 205-1 can be equipped with a hex wrench for rotational connection. Increasing the torque with the wrench allows for the rotation of the pivot 205.

[0040] In this embodiment, a support bushing 201-5 is provided inside the extension rod 201 corresponding to one end of the stop cap 206. The support bushing is sleeved on the rotating shaft 205 to support the rotating shaft 205.

[0041] In this embodiment, the stop cap 206 is provided with a flange 206-1, and the flange 206-1 is provided with end face tooth structures evenly distributed. The retaining ring 202 is provided with end face tooth structures corresponding to the flange 206-1. The clamping nut 207 is tightened so that the two end face tooth structures mesh to fix the stop cap 206 on the extension rod 201.

[0042] See Figure 3 The stop cap 206 has several flat portions 206-2 spaced apart on its outer circumference. The flat portions 206-2 can be used to apply a wrench to restrict the rotation of the stop cap 206 when tightening the clamping nut 207.

[0043] See Figure 4 The extension rod 201, corresponding to one end of the mounting base 300, is sequentially connected to an optical shaft portion 201-1, a key portion 201-2, and a threaded portion 201-3. The inner ring of the bearing portion 301 is fitted onto the optical shaft portion 201-1. The pressure sleeve 203 has a keyhole 203-1 corresponding to the key portion 201-2, and the pressure sleeve 203 is slidably mounted on the key portion 201-2 through the keyhole 203-1. The pressure cap 204 has a pressure cap threaded hole 204-1 on one side, and the pressure cap 204 is threadedly connected to the threaded portion 201-3 through the pressure cap threaded hole 204-1.

[0044] The pressure sleeve 203 is made of copper, and copper friction rings 304 are provided on both sides of the outer ring of the bearing part 301. The friction rings 304 abut against the pressure sleeve 203 to increase friction.

[0045] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
