The cable is connected to the sensing component, and the cable lock is engaged with the end of the probe sleeve away from the probe sleeve, sealing the probe assembly. This installation method is mainly for the installation of the insertion flow meter, but it still relies on manual installation, which can lead to errors. Therefore, this invention is proposed. Summary of the Invention

[0004] To address the shortcomings of existing technologies, this invention provides an insertion flow meter installation device that assists in locating and drilling the insertion flow meter, ensuring precise positioning, reducing human error in measurement and locating, improving measurement accuracy, and ensuring accurate installation of the flow meter to meet on-site usage requirements.

[0005] The present invention also provides an installation method for the above-described insertion flow meter installation device.

[0006] The technical solution of the present invention is as follows:

[0007] An insertion flow meter installation device includes a support platform, a first clamping device, a second clamping device, a positioning block, a V-shaped support device, a rotating device, and a bottom lifting device, wherein...

[0008] A support platform is provided on the upper side of the bottom lifting device via a rotating device. A horizontal guide rail is provided on the support platform. A vertical guide rail is provided on one side of the horizontal guide rail via a sliding support plate. A first clamping device is provided on the vertical guide rail. A second clamping device is provided on the other side of the horizontal guide rail. A handwheel rotation mechanism is connected to the bottom of both the vertical guide rail and the second clamping device.

The upper part of the first clamping device is symmetrically equipped with dovetail groove-shaped tracks, and a positioning block is slidably arranged between the two dovetail groove-shaped tracks. A tooth is vertically arranged on one side of the positioning block, and the tooth is meshed with a gear. The gear is fixed to the outside of the first clamping device by a fixing frame. A rocker arm is movably arranged on the fixing frame by a pin shaft. The end of the rocker arm is connected to a gear by an arc-shaped tooth. The rotation of the gear is adjusted by swinging the rocker arm, thereby adjusting the height of the positioning block. A scale line is provided on one side of the first clamping device of the fixing frame to facilitate the identification of the height of the positioning block.

[0010] According to a further preferred embodiment of the present invention, a V-groove is provided inside the positioning block, and a threaded positioning sleeve is provided inside the V-groove, which penetrates the positioning block. The threaded positioning sleeve is a bolt with a built-in through hole. The probe base of the insertion flow meter is fixed by the threaded positioning sleeve. The V-groove design has two effects: first, it facilitates clamping the pipe, and second, it provides installation space for the probe base after clamping the pipe.

[0011] According to a preferred embodiment of the present invention, the fixing frame is a C-shaped frame with the open side facing upwards. A locking structure is provided on the lower side of the fixing frame. The locking structure includes a locking shaft, a torsion spring, and a V-shaped plate. The locking shaft is fixed to the fixing frame, and a torsion spring is provided on the locking shaft. One end of the torsion spring contacts the edge of the fixing frame, and the other end is fixedly connected to the V-shaped plate. One side of the V-shaped plate faces outwards, and the other side is connected to a gear. When the gear rotates downwards, it pushes the V-shaped plate downwards. After the rotation stops, the V-shaped plate returns to its original position under the elastic force of the torsion spring, fixing the position of the gear. When the positioning block needs to be moved upwards, the outward-facing side of the V-shaped plate is manually lifted, and the other side of the V-shaped plate disengages from the gear, no longer limiting the gear. The positioning block can then be moved upwards manually.

[0012] According to a preferred embodiment of the present invention, a scale is provided on the upper side of the vertical guide rail, a locking handwheel is provided on one side of the first clamping device via a fixing plate, a T-shaped marker is provided on one side of the fixing plate, and the lower side of the T-shaped marker points to the scale. After the first clamping device moves to the designated position, the locking handwheel is rotated downwards, and the position is locked by the fixed contact between the locking handwheel and the vertical guide rail.

[0013] According to a preferred embodiment of the present invention, the handwheel rotation mechanism includes a traction link, a rotating wheel, a rotating shaft, and a bearing seat. The two sides of the rotating shaft are respectively fixed to the support platform through the bearing seat. The two sides of the rotating shaft extend through the V-shaped support device. Two rotating wheels are fixedly installed inside the rotating shaft. The two sides of the rotating wheels are respectively connected to a vertical guide rail and a second clamping device through the traction link. The rotation of the rotating wheels drives the traction link on both sides to move, thereby driving the vertical guide rail and the second clamping device to move.

[0014] According to a preferred embodiment of the present invention, the rotating device includes a cylindrical hollow base and a cylindrical connecting plate. The connecting plate is embedded in the base via a bearing. The base is fixed to the bottom support device. A support platform is provided on the top of the connecting plate.

The locking mechanism includes a fixed seat and a locking block. A sliding groove is provided inside the fixed seat, and the locking block is spring-loaded into the sliding groove. Reset posts extending from the fixed seat are provided on both sides of the locking block. After the support platform moves to the designated position, the reset posts are locked into the locking groove under the spring force, thus locking the position of the support platform.

[0016] According to a preferred embodiment of the present invention, handles are provided on both sides of the support platform for easy rotation.

[0017] According to a preferred embodiment of the present invention, the bottom lifting device includes a mobile trolley, a hydraulic telescopic cylinder, a bottom support plate, an upper support plate, and an angle adjuster.

[0019] ① The mobile trolley is moved to the installation position, and then the hydraulic telescopic cylinder extends to lift the support platform to the installation height. The position of the support platform is rotated by the rotating device, and the angle of the upper support plate is adjusted so that the upper support plate is parallel to the axial surface of the pipeline. The V-shaped support device contacts and fits against the bottom of the pipeline where the flow meter is to be installed for support.

[0020] ② By rotating the shaft, the rotating wheel is driven to rotate, and then the second clamping device and the vertical guide rail are driven to move synchronously towards the center along the horizontal guide rail through the traction link.

[0023] ⑤ Connect the threaded positioning sleeve to the probe base of the insertion flow meter, then rotate the threaded positioning sleeve to make the front end of the probe base fit tightly with the pipeline, thus completing the insertion flow meter positioning. Then weld the probe base to the pipeline.

[0024] ⑥ Remove the installation device, connect the ball valve to the probe base, turn the ball valve open, then start drilling to make a hole. After the hole is clear, close the ball valve, insert the sensor, and complete the installation of the insertion flow meter.
