Description

Technical Field

[0001] The utility model relates to the field of vortex flow meters, in particular to an anti-theft vortex flow meter. Background Art

[0002] A vortex flow meter is a volumetric flow meter that measures the volumetric flow rate, standard volumetric flow rate, or mass flow rate of gas, steam, or liquid based on the Karman vortex street principle. It is mainly used for measuring the flow rate of fluid in industrial pipelines, such as various media like gas, liquid, and steam.

[0003] Currently, enterprises supplying steam or natural gas all use vortex flow meters as metering instruments for price settlement. Traditional vortex flow meters do not have anti-theft functions. For example, the anti-vibration structure of a vortex flow meter in the Chinese patent CN219935015U applied by our company has anti-vibration performance but does not have anti-theft function. Various means are often used to affect the normal operation of the vortex flow meter to achieve the purpose of stealing gas, such as opening the shell of the transmitter (detection head) and damaging the temperature signal line, pressure signal line, flow signal line, or power supply line.

[0004] Therefore, some existing flow meter manufacturers have set up simple anti-theft structures, that is, adding lead seals or locks to the vortex flow meters to achieve the anti-theft purpose. Even so, there are still ways to access the flow meter and tamper with it to achieve the purpose of theft, such as imitating the lead seals and finding a locksmith company to unlock the lock. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-theft vortex flow meter.

[0006] The innovation point of the utility model lies in that the application prevents theft through a monitoring component and an acceleration sensor, with a simple structure, low transformation cost, and good anti-theft effect.

[0007] To achieve the above-mentioned utility model purpose, the technical solution of the utility model is:

[0008] An anti-theft vortex flowmeter, comprising a pipeline, a sensor fixing seat communicated with the side wall of the pipeline is arranged, a flowmeter is arranged in the sensor fixing seat, and a probe of the flowmeter extends into the pipeline; a bracket fixing seat is sleeved outside the sensor fixing seat, a support shell is arranged on the bracket fixing seat, a detection head is arranged at the top of the support shell, and cover bodies are respectively arranged on two opposite sides of the detection head; an acceleration sensor is arranged on the bracket fixing seat; a monitoring component for detecting the switch state of the cover body is arranged on the cover body; a control module, a display module, an alarm module and a wireless transmission module are arranged in the detection head; the acceleration sensor and the monitoring component are both connected with the alarm module, and the alarm module, the display module and the wireless transmission module are all connected with the control module.

[0009] Further, the monitoring component includes a magnetic element arranged on the cover body and a Hall element arranged inside the detection head.

[0010] Further, the support shell and the bracket fixing seat are connected by a flange and bolts.

[0011] Further, the sensor fixing seat and the bracket fixing seat are welded to the pipeline.

[0012] The beneficial effects of the utility model are as follows:

[0013] First: In this application, a monitoring module is arranged on the cover body of the detection head to detect whether the cover body is opened; meanwhile, an acceleration sensor is arranged. Once a theft behavior occurs, such as: the acceleration sensor vibrates due to the disassembly of the support shell, the acceleration sensor tilts due to the disassembly of the pipeline, etc., an alarm can be given. The structure is simple, the transformation cost is low and the anti-theft effect is good.

[0014] Second: By arranging a control module, an alarm module and a wireless transmission module, real-time alarm can be given and information can be sent to a remote control center. Description of the Drawings

A flowmeter 3 is arranged in the sensor fixing base 2, and the probe of the flowmeter 3 extends into the pipeline 1. A bracket fixing base 4 is sleeved outside the sensor fixing base 2. A support housing 5 is arranged on the bracket fixing base 4. A detection head 6 is arranged at the top of the support housing 5. Cover bodies 7 are respectively arranged on two opposite sides of the detection head 6. An acceleration sensor 8 is arranged on the bracket fixing base 4.

[0022] Further, the acceleration sensor 8 has an inclination detection function (inclination sensor) and can be directly purchased from the market. When theft or damage occurs, such as the vibration of the bracket fixing base 4 caused by the disassembly of the support housing 5, which in turn causes the vibration of the acceleration sensor 8. When the acceleration information is greater than a predetermined value, the control module 10 can alarm, and at the same time, the information can be sent to the remote control center through the wireless transmission module 13. In addition, if the behavior of directly disassembling the flowmeter (directly disassembling the pipeline 1) occurs, causing the bracket fixing base 4 to tilt, which in turn causes the acceleration sensor 8 to tilt. When the tilt angle exceeds the predetermined value, the control module 10 can alarm, and at the same time, the information can be sent to the remote control center through the wireless transmission module 13.
