Description

Technical Field

[0001] The present invention relates to the technical field of turbine flowmeters, and more particularly to a turbine flowmeter detector. Background Art

[0002] A turbine flowmeter is a precision instrument for measuring fluid flow. It uses a movement to generate high-frequency vibrations and drives a magnetic induction probe (i.e., a magnetic induction turbine) to work, thereby detecting a flow signal.

[0003] According to the patent with publication (announcement) number CN101532854B and publication (announcement) date January 5, 2011, a disclosed turbine flowmeter detection device includes a flow integrator and a housing. Airflow flows into one end of the housing and out of the other end. The key points are as follows: a rectifier and an impeller assembly are arranged in one of the housings; a magnetic sensor and a fault sensor fixed in one of the housings are respectively connected to the flow integrator; the fault sensor, the magnetic sensor, the rectifier, and the impeller assembly are arranged in one of the housings, and one of the housings and the flow integrator are combined into an integral type. The fault signal detected by the fault sensor and the flow signal detected by the magnetic sensor are respectively displayed on the display screen of the flow integrator; the installation position and sequence of the fault sensor can be adjusted according to the different calibers of the housing. This device is implemented based on the principle of the fluid flow velocity detected by the fault sensor installed in the turbine flowmeter: that is, the detected velocity signal is converted into a flow signal, compared with the flow signal detected by the magnetic sensor, and when there is a deviation between the two, it indicates the existence of a fault, and the fault signal is displayed on the liquid crystal display screen of the flow integrator to achieve the purpose of automatic fault detection; at the same time, according to needs, the fault information and other parameters can be output remotely.

[0004] In the prior art including the above patent, during pipeline maintenance work, it is necessary to measure the turbine flowmeter. Generally, the measurement method is to use an ultrasonic detector for detection. During the detection work, the staff needs to manually attach the ultrasonic probe to the outer wall of the pipeline, use ultrasonic waves to detect the flow in the pipeline, and compare the measured data with the numerical change of the turbine flowmeter to detect the turbine flowmeter. However, the data detected by the ultrasonic detector is affected by the inclination angle of the ultrasonic probe, and it is difficult for the staff to ensure that the ultrasonic probe is directly facing the center of the pipeline when manually attaching the ultrasonic probe to the outer wall of the pipeline. Summary of the Invention

[0005] The purpose of the present invention is to provide a turbine flowmeter detector, aiming to solve the above problems.

[0006] To achieve the above object, the present invention provides a turbine flowmeter detector, which includes a mounting ring composed of two mounting half-rings. A plurality of clamping blocks and a plurality of blocking rods are movably arranged on the mounting half-rings. A movable half-ring is slidably arranged on the mounting half-rings. A supporting rod for supporting an ultrasonic probe is slidably arranged on the movable half-ring. The supporting rod abuts against one of the blocking rods. The clamping blocks move to synchronously move the blocking rods. The clamping blocks abut against the outer wall of the pipeline. The blocking rods push the supporting rod so that the ultrasonic probe synchronously abuts against the outer wall of the pipeline. The movable half-ring moves so that the detection position of the ultrasonic probe is adjustable.

[0007] Preferably, a driving half-ring for driving the clamping blocks and the baffle plates to move synchronously is slidably arranged on the mounting half-rings. Two driving half-rings form a driving ring that moves in the mounting ring.

[0008] Preferably, a sliding rod extending into the interior of the mounting half-ring is arranged on the clamping block.

[0009] Preferably, a first flat thread for driving the sliding rod to move is arranged on the side wall of the driving ring. A sliding groove adapted to the first flat thread is arranged on the sliding rod.

[0010] Preferably, a connecting rod extending into the interior of the mounting half-ring is arranged on the blocking rod.

[0011] Preferably, a second flat thread for driving the connecting rod to move is formed on the side wall of the driving ring. A sliding groove adapted to the second flat thread is arranged on the connecting rod.

[0012] Preferably, a dial rod extending to the outside of the mounting half-ring is arranged on the driving half-ring. A notch for the dial rod to move is formed on the mounting half-ring.

[0013] Preferably, a movable rod is slidably arranged on the movable half-ring. A notch for the dial rod to move is formed on the mounting half-ring.

[0014] Preferably, the movable rod moves relative to the movable half-ring so that the ultrasonic probe retracts into the supporting rod.

[0015] Preferably, a sliding plate facing the movable rod is slidably arranged on the supporting rod. A cable is arranged between the sliding rod and the ultrasonic probe.

[0016] In the above technical solution, a turbine flowmeter detector provided by the present invention has the following beneficial effects: When performing detection work, align two installation half-rings to form an installation ring and sleeved on the outside of the pipeline, and use bolts to fix the two installation half-rings together. Then, drive multiple clamping blocks and multiple blocking rods to move synchronously. The multiple clamping blocks abut against the outer wall of the pipeline to fix the installation ring on the outer wall of the pipeline, and the installation ring is concentric with the pipeline. And the blocking rod pushes the supporting rod towards the outer wall of the pipeline until the ultrasonic probe on the supporting rod abuts against the outer wall of the pipeline. Since the supporting rod faces the axis of the installation ring, the ultrasonic probe on the supporting rod also faces the axis of the installation ring. The installation ring is concentric with the pipeline, and the ultrasonic probe faces the axis of the pipeline, which is convenient for the ultrasonic detector to detect the internal flow of the pipeline and compare the measured data with the numerical change of the turbine flowmeter to detect the turbine flowmeter; The above installation ring can be two, and the two installation rings are respectively fixed upstream and downstream of the turbine flowmeter to detect the flow respectively, and judge whether there is liquid leakage according to the flow difference.

[0026] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further introduced in detail below in conjunction with the accompanying drawings.

[0027] As Figures 1-6 shown, a turbine flowmeter detector includes an installation ring 1 composed of two installation half-rings 11. A plurality of clamping blocks 123 and a plurality of stop bars 125 are movably arranged on the installation half-ring 11. A movable half-ring 131 is slidably arranged on the installation half-ring 11. A supporting rod 132 for supporting the ultrasonic probe 2 is slidably arranged on the movable half-ring 131. The supporting rod 132 abuts against one of the stop bars 125. The clamping blocks 123 move to synchronously move the stop bars 125. The clamping blocks 123 abut against the outer wall of the pipeline. The stop bars 125 push the supporting rod 132 to synchronously abut the ultrasonic probe 2 against the outer wall of the pipeline. The movable half-ring 131 moves to make the detection position of the ultrasonic probe 2 adjustable.

[0028] Specifically, installation plates 111 are arranged on both installation half-rings 11. The installation plates 111 on the two installation half-rings 11 are closely attached and fixed with bolts, so as to form the installation ring 1 sleeved on the pipeline by the two installation half-rings 11.

[0029] In the above technical solution, during the detection work, the two installation half-rings 11 are aligned to form the installation ring 1 and sleeved on the outer side of the pipeline, and the two installation half-rings 11 are fixed together with bolts. Then, a plurality of clamping blocks 123 and a plurality of stop bars 125 are driven to move synchronously. The plurality of clamping blocks 123 abut against the outer wall of the pipeline, and the installation ring 1 is fixed on the outer wall of the pipeline, and the installation ring 1 is concentric with the pipeline. And the stop bar 125 pushes the supporting rod 132 to approach the outer wall of the pipeline until the ultrasonic probe 2 on the supporting rod 132 abuts against the outer wall of the pipeline. Since the supporting rod 132 faces the axis of the installation ring 1, the ultrasonic probe 2 on the supporting rod 132 also faces the axis of the installation ring 1. The installation ring 1 is concentric with the pipeline, and the ultrasonic probe 2 faces the axis of the pipeline, which is convenient for the ultrasonic detector to detect the internal flow of the pipeline and compare the measured data with the numerical change of the turbine flowmeter, so as to detect the turbine flowmeter. The above installation rings 1 can be two, and the two installation rings 1 are respectively fixed upstream and downstream of the turbine flowmeter to detect the flow respectively, and judge whether there is liquid leakage according to the flow difference.

[0030] As a further embodiment provided by the present invention, a driving semi-ring 121 for driving the clamping block 123 and the blocking rod 125 to move synchronously is slidably arranged on the mounting semi-ring 11. Two driving semi-rings 121 form a driving ring 12 that moves in the mounting ring 1. A sliding rod 122 extending into the interior of the mounting semi-ring 11 is arranged on the clamping block 123. A first flat thread for driving the sliding rod 122 to move is arranged on the side wall of the driving ring 12. A sliding groove adapted to the first flat thread is arranged on the sliding rod 122. A connecting rod 124 extending into the interior of the mounting semi-ring 11 is arranged on the blocking rod 125. A second flat thread for driving the connecting rod 124 to move is formed on the side wall of the driving ring 12. A sliding groove adapted to the second flat thread is arranged on the connecting rod 124. A dial rod 126 extending to the outside of the mounting semi-ring 11 is arranged on the driving semi-ring 121. A notch for the dial rod 126 to move is formed on the mounting semi-ring 11.

[0031] Specifically, when performing the fixing work, two mounting semi-rings 11 form the mounting ring 1, and the driving semi-rings 121 in the two mounting semi-rings 11 form the driving ring 12. And there is a ring groove in the mounting ring 1 for the driving ring 12 to drive. Manually push the dial plate, the dial rod 126 drives the driving ring 12 to rotate. The first flat thread on the driving ring 12 moves along the sliding groove on the sliding rod 122, pushing the sliding rod 122 and the clamping block 123 towards the pipeline. The clamping block 123 gradually abuts against the outer wall of the pipeline and fixes the mounting ring 1 on the pipeline. The mounting ring 1 is coaxial with the pipeline. At the same time, the second flat thread on the driving ring 12 moves along the sliding groove on the connecting rod 124, pushing a plurality of connecting rods 124 and the blocking rod 125 towards the pipeline. And one of the blocking rods 125 pushes the supporting rod 132, making the ultrasonic probe 2 approach the pipeline, which is convenient for detecting the internal flow rate of the pipeline by using ultrasonic waves.

[0032] As yet another embodiment further provided by the present invention, a movable rod 133 is slidably arranged on the movable semi-ring 131. A notch for the movable rod 133 to move is formed on the mounting semi-ring 11. The movable rod 133 moves relative to the movable semi-ring 131 so that the ultrasonic probe 2 retracts into the supporting rod 132. A sliding plate 134 facing the movable rod 133 is slidably arranged on the supporting rod 132. A cable 135 is arranged between the sliding plate 134 and the ultrasonic probe 2.

[0033] Specifically, a spring is arranged between the ultrasonic probe 2 and the supporting rod 132. A scale for indicating the central position of the blocking rod 125 is arranged on the mounting semi-ring 11. Two movable semi-rings 131 form a movable ring 13. The two supporting rods 132 on the movable ring 13 are opposite to each other. A spring is arranged between the supporting rod 132 and the movable semi-ring 131.

[0034] Further, after detecting at one point, press the two movable rods 133. The movable rods 133 squeeze the sliding plate 134 on the supporting rod 132. The sliding plate 134 moves into the interior of the supporting rod 132 and pulls the ultrasonic probe 2 through the cable 135, so that the ultrasonic probe 2 retracts into the supporting rod 132. At this time, the movable rods 133 can be pushed to move along the notch on the mounting half-ring 11, driving the movable ring 13 to rotate relative to the mounting ring 1 until the supporting rod 132 moves to a position opposite to another stop rod 125. Release the movable rods 133, and the ultrasonic probe 2 is pushed by the spring to re-abut against the outer wall of the pipeline, and the internal flow of the pipeline can be detected from different angles.

[0035] Only some exemplary embodiments of the present invention have been described by way of illustration above. Without doubt, for those of ordinary skill in the art, the described embodiments can be modified in various different ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
