Description

Technical Field

[0001] The utility model belongs to the technical field of flow detection, in particular to a clamp for online flow detection. Background Art

[0002] The measurement principle of electromagnetic flowmeter is based on Faraday's law of electromagnetic induction. That is, when the conductive liquid flows through the electromagnetic flowmeter, a voltage proportional to the average flow velocity V (volume flow) will be generated in the conductive liquid. The induced voltage signal is detected by two electrodes in contact with the liquid, transmitted to the amplifier through the cable, and then converted into a unified output signal.

[0003] like Fig. 9 When an electromagnetic flowmeter is needed to detect the liquid flow in a pipeline, two detection devices need to be fixed on both sides of the pipeline. In the prior art, manual fixation is directly adopted. This fixing method requires one person to fix the detection device on both sides of the pipeline, and another person to operate the equipment, which is very inconvenient. In addition, it is not convenient to place the detection device when detecting pipelines arranged close to buildings.

[0004] There are also some Fig.10 The clamp is composed of two baffles and two clamping parts. The baffle is composed of a vertical plate and a horizontal plate. The vertical plate and the horizontal plate are vertically connected, and the long side of the lower side of the vertical plate coincides with the long side of the rear side of the horizontal plate. Two long sliding holes are arranged on the vertical plate, and the two long sliding holes are distributed on the same straight line on the left and right sides. A leveling part is respectively provided at the left and right ends of the horizontal plate. The two baffles are arranged opposite to each other, and the two clamping parts can move along the long sliding holes and are fixed by nuts. Although this prior art has a leveling part, which is convenient for attaching the detection device to the pipeline, it still needs to be fixed manually. Utility Model Content

[0007] The above-mentioned fixture for online flow detection is characterized in that at least one spacing groove is provided on the vertical surface, and a mounting groove is provided on the clamping surface corresponding to the spacing groove, and the magnetic attraction component is fixed in the mounting groove.

[0008] The above-mentioned fixture for online flow detection is characterized in that the magnetic attraction component is a butterfly hinge, one hinge of the butterfly hinge is fixed in the corresponding installation groove, and at least one magnet is fixed on the other hinge of the butterfly hinge.

[0009] The above-mentioned fixture for online flow detection is characterized in that the magnetic attraction component is a hinge group, the hinge group is composed of at least three hinges, two adjacent hinges are connected by a rotating shaft, and at least one magnet is fixed on the hinge of each hinge group.

[0010] The above-mentioned clamp for online flow detection is characterized in that a rubber pad is provided on the clamping surface to prevent slipping.

[0011] The above-mentioned fixture for online flow detection is characterized in that the nut is a butterfly nut.
