Description

Portable radar current meter Technical Field The utility model relates to the technical field of radar flowmeters, in particular to a portable radar flowmeter. Background The radar flow rate meter is an instrument for measuring the water flow speed by utilizing the radar wave technology based on the Doppler effect principle, and calculates the flow rate by transmitting high-frequency radar waves and receiving reflected signals of tiny particles (such as water drops and bubbles) on the water surface and analyzing the frequency shift. The traditional radar current meter often needs manual handheld operation when measuring, has increased operating personnel's intensity of labour, probably produces because unsettled reason and rocks to cause measurement data error, in measurement for a long time or under the complex environment moreover, the stability of manual work gripping is difficult to guarantee, probably drops because of holding lax. Therefore, a new technical scheme is provided for solving the problems. Disclosure of utility model The utility model aims to provide a portable radar flow rate meter, which solves the problems that the traditional radar flow rate meter provided in the background art often needs manual handheld operation during measurement, measurement data errors can be caused by shaking, the stability of manual holding is difficult to ensure, and the traditional radar flow rate meter can fall down due to loose holding. In order to achieve the purpose, the portable radar flow velocity meter comprises a flow velocity meter main body and a bottom plate, wherein the bottom of the flow velocity meter main body is connected with a telescopic rod in a sliding mode, the bottom end of the telescopic rod is fixedly connected with a rotating rod, the top end of the bottom plate is fixedly connected with two fixing plates, the rotating rod penetrates through the two fixing plates and is rotationally connected with the fixing plates, and one side of a grip of the flow velocity meter main body is provided with a base plate and a limiting ring. In this kind of technical scheme, set up the telescopic link in the bottom of current meter main part, can stretch out and support by the bottom plate in suitable position, stability when improving the measurement sets up backing plate and spacing ring simultaneously and carries out spacingly to the arm, increases the stability of gripping, has avoided not holding tightly and has led to the condition emergence of taking off the hand to the security and the stability of device have been improved. Preferably, the front side wall and the rear side wall of the grip of the flow velocity meter main body are respectively and rotatably connected with a sleeve connection rod, the inner side of the sleeve connection rod is connected with a supporting frame in a sliding manner, and the top end of the supporting frame is fixedly connected with a backing plate. In the technical scheme, the support frame can freely stretch the length, limit the proper arm position, fix the length by the screw at the top end of the sleeve connecting rod, and avoid the support frame from completely sliding out of the sleeve connecting rod. Preferably, screw threads are formed on the surfaces of the two ends of the rotating rod, and the two ends of the rotating rod are connected with extrusion nuts in a threaded manner. In this kind of technical scheme, extrusion nut can tightly extrude the dwang after screwing up, and the dwang can not free rotation this moment to guaranteed the stability of below bottom plate, avoided its free rotation to lead to supporting to rock. Preferably, the front surface and the rear surface of the grip of the flow velocity meter main body are fixedly connected with two limiting blocks, and one limiting block is contacted with the top end of the horizontal sleeving rod. In this kind of technical scheme, the stopper can block spacingly to the different service conditions of cover extension rod, guarantees that the cover extension rod can stably support and not freely rotate, and horizontally stopper blocks the cover extension rod when holding, and the stopper of slope then blocks the cover extension rod that rotates the current meter place ahead. Preferably, the top edge of the backing plate is rotationally connected with a limiting ring through a hinge, and the movable end of the limiting ring is detachably connected with the backing plate through a fixing bolt.
