Description

Technical Field

[0001] This utility model relates to the field of radar current meter technology, specifically a portable radar current meter. Background Technology

[0002] A radar current meter is an instrument that measures the velocity of water flow based on the Doppler effect principle and using radar wave technology. It calculates the flow velocity by emitting high-frequency radar waves and receiving the reflected signals from tiny particles (such as water droplets and bubbles) on the water surface and analyzing the frequency shift.

[0003] Traditional radar current meters often require manual hand-held operation during measurement, increasing the operator's workload. The instrument may also sway due to being suspended in the air, leading to measurement errors. Furthermore, the stability of the manual grip is difficult to guarantee during long-term measurements or in complex environments, and the instrument may fall due to a loose grip. Therefore, a new technical solution is proposed to address these issues. Utility Model Content

[0004] The purpose of this utility model is to provide a portable radar current meter, which solves the problems mentioned in the background art that traditional radar current meters often require manual hand-held operation during measurement, which may cause measurement data errors due to shaking, and the stability of manual holding is difficult to guarantee, and may fall due to loose grip.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a portable radar current meter, comprising a current meter body and a base plate, wherein a telescopic rod is slidably connected to the bottom of the current meter body, the bottom end of the telescopic rod is fixedly connected to a rotating rod, two fixed plates are fixedly connected to the top of the base plate, the rotating rod passes through the two fixed plates and is rotatably connected to the fixed plates, and a pad and a limiting ring are provided on one side of the handle of the current meter body.

[0006] In this technical solution, a telescopic rod is installed at the bottom of the flow meter body, which can be extended to a suitable position and supported by the base plate to improve the stability during measurement. At the same time, a pad and a limiting ring are set to limit the arm, increase the stability of the grip, and prevent the device from slipping out of the hand due to insufficient grip, thereby improving the safety and stability of the device.

[0007] Preferably, the front and rear side walls of the handle of the flow meter body are rotatably connected with sleeve rods, the inner side of the sleeve rods is slidably connected with a support frame, and the top of the support frame is fixedly connected with a pad.

[0008] In this technical solution, the support frame can be freely stretched to a suitable arm position, and its length is fixed by a screw at the top of the socket rod, preventing the support frame from completely sliding out of the socket rod.

[0009] Preferably, both ends of the rotating rod are threaded, and both ends of the rotating rod are threaded with compression nuts.

[0010] In this technical solution, after the compression nut is tightened, it can tightly squeeze the rotating rod, preventing the rotating rod from rotating freely. This ensures the stability of the base plate below and prevents the support from shaking due to free rotation.

[0011] Preferably, two limiting blocks are fixedly connected to the front and rear surfaces of the handle of the flow meter body, one of which is in contact with the top of the horizontal sleeve rod.

[0012] In this technical solution, the limiting block can block and limit the socket rod in different usage situations, ensuring that the socket rod can be stably supported and not rotate freely. The horizontal limiting block blocks the socket rod when it is held, while the inclined limiting block blocks the socket rod when it rotates to the front of the flow meter.

[0013] Preferably, a limiting ring is rotatably connected to the top edge of the pad via a hinge, and the movable end of the limiting ring is detachably connected to the pad via a fixing bolt.

[0014] In this technical solution, the limiting ring can encircle the arm, thereby limiting the arm and preventing the equipment from falling and breaking when the hand is suddenly released, thus improving safety.

[0015] Preferably, soft pads are fixedly connected to the top of the pad and the inner ring surface of the limiting ring.

[0016] In this technical solution, the soft pad can cushion and protect the arm, preventing the sharp edges of the pad and the limiting ring from causing damage to the skin.

[0017] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0018] 1. This utility model improves the stability of measurement by setting a telescopic rod at the bottom of the flow meter body, which can be extended to a suitable position and supported by the base plate. At the same time, the pad and the limiting ring limit the arm, increasing the stability of the grip and preventing the device from slipping out of the hand due to insufficient grip. This improves the safety and stability of the device during use.

[0019] 2. This utility model is equipped with a rotatable connecting rod. When in use, the connecting rod, the pad, and the limiting ring are rotated to the front of the handle and the limiting ring is opened. At this time, it can be placed stably with the base plate, which makes it convenient to take the flow meter out of your hand and place it in a fixed position for measurement, thus improving the convenience and practicality of the device.

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the following description will further elaborate on them in conjunction with specific embodiments.

[0025] A portable radar current meter, see Figures 1 to 2 The device includes a flow meter body 1 and a base plate 4. A telescopic rod 2 is slidably connected to the bottom of the flow meter body 1. The telescopic rod 2 is stored inside the handle of the flow meter body 1. When not extended, only the base plate 4 is exposed. The bottom end of the telescopic rod 2 is fixedly connected to a rotating rod 3. Two fixing plates 401 are fixedly connected to the top of the base plate 4. The rotating rod 3 passes through the two fixing plates 401 and is rotatably connected to the fixing plates 401. Both ends of the rotating rod 3 are threaded, and both ends of the rotating rod 3 are threaded with compression nuts 301. A pad 7 and a limiting ring 8 are provided on one side of the handle of the flow meter body 1. In use, the telescopic rod 2 is pulled out and each section of the telescopic rod 2 is tightened to the maximum extent to maintain stability. Then, the base plate 4 is supported in a suitable position (such as the ground), thereby improving the stability during the measurement process. At the same time, the pad 7 and the limiting ring 8 can support and limit the arm when holding the device, increasing the stability of the grip and preventing the device from slipping out of the hand due to insufficient grip, thereby improving the safety and stability of the device.

[0026] It should be noted that when the base plate 4 is placed, since the staff keeps holding it manually, the base plate 4 acts as a fulcrum from below. Compared to holding the device in the air, the base plate 4 placed below can greatly improve stability, ensuring that it will not shake up and down during the measurement process and improving the accuracy of the measurement.

[0027] Specifically, such as Figure 1 and Figure 2As shown, the front and rear side walls of the handle of the flow meter body 1 are rotatably connected to a sleeve rod 5. The inner side of the sleeve rod 5 is slidably connected to a support frame 6. The top of the support frame 6 is fixedly connected to a pad 7. In actual use, the length of the support frame 6 can be adjusted according to the grip position and the arm position of different users. After adjustment, the arm can be fixed. Each section of the telescopic rod 2 will remain stable when pulled to the maximum extent. The rotation of the sleeve rod 5 also has a large damping effect, thus playing a partial limiting role.

[0028] Furthermore, such as Figure 1 and Figure 2 As shown, a limiting ring 8 is rotatably connected to the top edge of the pad 7 via a hinge. The movable end of the limiting ring 8 is detachably connected to the pad 7 via a fixing bolt 801. The pad 7 is located below the arm. Then, the limiting ring 8 is rotated to close and fixed with the fixing bolt 801, thereby limiting the arm and improving the stability and safety when holding it. Soft pads 10 are fixedly connected to the top of the pad 7 and the inner ring surface of the limiting ring 8. The soft pads 10 can cushion the arm and prevent bumps and scratches.

[0029] The direct explanation is that during use, the connecting rod 5, the pad 7, and the limiting ring 8 are rotated to the front of the handle and the limiting ring 8 is opened. At this time, it can be placed stably with the base plate 4, making it convenient to release the flow meter from the hand and place it in a fixed position for measurement, thus improving the convenience and practicality of the device. During this process, the telescopic rod 2 is completely retracted into the handle of the device, with only the base plate 4 exposed. After the connecting rod 5 and the support frame 6 are rotated to the front of the handle, a new support point is formed in front of the handle. After the limiting ring 8 is opened, it can cooperate with the pad 7 to form two inverted arc-shaped support structures in front, thus ensuring that the device can be placed in a fixed position without tipping over. The design has been verified that the support of the pad 7, the limiting ring 8, and the base plate 4 can ensure the stability of the center of gravity and achieve stable placement.

[0030] It is worth noting that, such as Figure 1 As shown, two limiting blocks 9 are fixedly connected to the front and rear surfaces of the handle of the flow meter body 1. One of the limiting blocks 9 contacts the top of the horizontal connecting rod 5, which plays a positioning role for the connecting rod 5. One of the limiting blocks 9 is horizontal and the other is inclined. The horizontal limiting block 9 ensures that the connecting rod 5 remains horizontal when held, while the inclined limiting block 9 can limit and block the connecting rod 5 that has rotated to the front side of the handle of the flow meter body 1, preventing it from continuing to rotate and maintaining stability.

[0031] In addition, all components designed in this utility model are general standard parts or components known to those skilled in the art. Their structure and principle can be learned by those skilled in the art through technical manuals or conventional experimental methods. Those skilled in the art can fully implement them, so there is no need to elaborate. The content protected by this utility model does not involve improvements to the internal structure and method.
