Abstract
Description
Technical Field
[0001] This utility model belongs to the technical field of flow velocity detectors, and specifically relates to a water flow velocity detector. Background Technology
[0002] Portable flow meters are widely used due to their advantages such as ease of carrying and accurate measurement. They are known to be used for flow velocity and flow rate measurement. When measuring outdoors, the flow meter is first connected to the measuring rod with a connecting cable. After connection, a person holds one end of the measuring rod and puts the other end into the water. After a certain period of time, the flow velocity of the water is detected.
[0003] Currently, sometimes personnel use a portable current meter to measure water flow velocity from the shore. However, the length of a person's arm is relatively short, making it impossible to select a measurement point for water flow beyond the arm's length. In addition, during the water flow velocity measurement process, the person not only needs to hold the measuring rod vertically, but also needs to operate the speed measuring host, which makes the water flow velocity measurement operation cumbersome and makes it difficult to maintain an accurate measurement posture. Utility Model Content
[0004] The purpose of this invention is to provide a water flow velocity detector to solve the problems mentioned in the background art.
[0005] To achieve the above objectives, this utility model provides the following technical solution: a water flow velocity detector, including a connector, a flow velocity measuring rod fixed at the lower end of the connector, and an extension support mechanism provided on the outside of the connector. The extension support mechanism includes an extension arm, a first stud, and a first knob. The first stud is fixed on one side surface of the connector, the extension arm is hinged to the connector, and the first knob is threaded onto the surface of the first stud. Through the provided ground support mechanism, the extension arm serves as an extension handle of the connector for personnel to hold and use from a distance, thereby facilitating the flow velocity measuring rod at the lower end of the connector to be submerged into the water flow at a greater distance for detection. When not in use, the extension arm can be stored outside the connector and provides a certain degree of pressure resistance and protection for the flow velocity measuring rod.
[0006] The lower end of the extended rotating arm is provided with a ground support mechanism, which includes a support frame and a support base. The support frame is hinged to the extended rotating arm, and the support base is fixed to the end of the support frame away from the extended rotating arm. Through the ground support mechanism, the flow velocity detector can be supported and placed on the ground on the shore by the support frame and the support base, thereby eliminating the cumbersome step of holding the connector part by hand during the detection process and improving the drawback of poor hand stability affecting the detection accuracy.
[0007] It should be noted in the solution that a first rotating groove is provided on one side surface of the extended rotating arm, and the first rotating groove of the extended rotating arm is rotatably matched with the first stud.
[0008] Further worth mentioning is that the one side surface of the extension arm is fixed with a second stud, and the surface of the second stud is threadedly sleeved with a second knob.
[0009] Further need to be explained is that the one side surface of the support turret is provided with a second rotating groove, and the second rotating groove of the support turret is rotationally matched with the second stud.
[0010] As a preferred embodiment, the one side surface of the first knob and the second knob is fixed with an anti-skid gasket.
[0011] As a preferred embodiment, the one end of the connecting head away from the flow speed measuring rod is fixed with a connecting wire, and the one end of the connecting wire away from the connecting head is fixed with a detector host.
[0012] Compared with the prior art, the water flow speed detector provided by the utility model has at least the following beneficial effects:
[0013] The extension arm is used as the extension handle of the connecting head for the personnel to hold from a far distance, so that the flow speed measuring rod at the lower end of the connecting head can be dived into the water flow at a far distance for detection, and the extension arm can be stored outside the connecting head when not in use and can play a certain pressure-resistant protection role for the flow speed measuring rod.
[0014] The flow speed detector can be supported and placed on the ground on the shore through the support turret and the support base, so that the cumbersome step of holding the connecting head during detection is omitted, and the poor hand-holding stability affecting the detection precision is improved.
