Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present new type shall be included in the protection scope of the present new type.

[0026] Embodiment 1

[0027] As Figs. 1-3 shown, a fast clamping tool for an ultrasonic flowmeter includes a flowmeter 9, one side of the flowmeter 9 is fixedly attached to the inner wall of a groove of a frame 1, and a plurality of elliptical rings 101 are fixed on the side walls of the frame 1.

[0028] One side of the flowmeter 9 is in contact and pressed against the side wall of a steel pipe 8, and the other side of the steel pipe 8 is in contact and pressed against a plurality of pressure blocks 3, the outer wall of each pressure block 3 is in sliding contact with the inner wall of the groove of each sliding block seat 5, and the work-shaped neck side wall of each pressure block 3 is in sliding contact with a bolt 6.

[0029] Each elliptical ring 101 is fixedly connected to a chain 2.

[0030] The shank of the bolt 6 below the work-shaped neck side wall is movably screwed through a bolt hole in one side wall of the sliding block seat 5.

[0031] There are four elliptical rings 101 fixed on the side walls of the frame 1, and two elliptical rings 101 are symmetrically fixed on each side wall of the frame 1.

[0032] Hooks 4 are fixedly installed on the side walls of the sliding block seat 5.

[0033] The other side wall of the steel pipe 8 is in contact and pressed against two pressure blocks 3.

[0034] A rubber pad 10 is also fixedly installed on the inner wall of the groove of the frame 1 to which one side of the flowmeter 9 is fixedly attached.

[0035] Preferably, the length of the shank of the bolt 6 below the work-shaped neck side wall is greater than the length of a single elliptical ring of the chain 2. The chain 2 is formed by a plurality of elliptical rings connected to each other.

[0036] A square hole 7 is also provided on one side wall of the frame 1.

[0037] The flowmeter 9 is an ultrasonic flowmeter, which is purchased from the FD-Q series of the Kinson Company, and the flowmeter 9 is powered by an external power supply. The type of the flowmeter 9 selected in the present patent is only for the convenience of description, and is not limited to the use of this type of instrument.

[0038] The new clamping tool is simple in structure and portable in use, and is mainly made of 304 stainless steel,

[0039] The frame 1 is sized to cooperate with the ultrasonic flow meter 9 and serves to fix the frame 1. Four elliptical rings 101 are welded and fixed on the upper surface of the frame 1 to fix the chain 2. The frame 1 is designed with rubber pads 10 at the contact position with the flow meter 9 to prevent the flow meter 9 from being abraded. The chain 2 has four chains each having a length of about 100 mm and serves to flexibly connect the frame 1 and the pressing block 3. The sliding block seat 5 is connected with the chain 2 through the hooks 4 and is provided with a bolt hole in the center to cooperate with the bolt 6. The work-shaped neck of the bolt 6 is slidably connected with the pressing block 3 and has high freedom. After the sliding block seat 5 is connected with the chain 2, the bolt 6 can be manually pre-tightened and locked until the pressing block 3 is tightly fitted with the outer wall of the pipeline of the steel pipe 8 and the flow meter 9 is fixed firmly. The sliding block seat 5 can move up and down with the tightening and loosening of the locking bolt 6. The contact surface with the pipeline is wedge-shaped and can realize the self-adaptive pressing function for different diameters of the pipeline.

[0040] The operation process of the clamping tool is briefly described as follows: when the flow rate in the DN15-DN50 pipeline is measured, the adhering matters on the surface of the steel pipe 8 are cleaned, the flow meter 9 is sleeved into the frame 1 and is placed on the upper surface of the steel pipe 8 together. The four chains 2 are vertically placed freely. At this time, the hooks 4 at both ends of the sliding block seat 5 are connected with the elliptical ring holes of the chain 2 according to the diameter of the measured steel pipe 8. The bolt 6 is manually rotated and locked. When the bolt body outside the sidewall of the work-shaped neck of the bolt 6 is screwed, the inner wall of the bolt hole of the sliding block seat 5 is screwed to interact with each other, so that the sliding block seat 5 is moved to pull the chain 2 tightly through the hooks 4. At the same time, the pressing block 3 is tightly fitted with the outer wall of the steel pipe 8, and the flow meter 9 is fixed firmly. If the signal strength of the flow meter 9 reaches the requirement, the locking bolt 6 can be stopped to complete the installation of the flow meter 9. The bolt 6 and the flow meter 9 can be directly purchased in the market.
