Description

Technical Field

[0001] This utility model relates to a flow meter, and more particularly to an intelligent vortex flow meter, belonging to the field of flow measurement instrument technology. Background Technology

[0002] Vortex flow meters are flow measurement instruments based on the Karman vortex street principle. They are characterized by simple structure, wide measurement range, and high accuracy, and are widely used in flow measurement in industrial production. However, existing intelligent vortex flow meters still have some technical shortcomings in use: the meter head of existing intelligent vortex flow meters is usually fixedly connected to the main body of the measuring pipe, and the display angle of the meter head cannot be adjusted.

[0003] In actual installation and use, due to the diverse pipeline layout methods (such as overhead pipelines, buried pipelines, vertical pipelines, etc.) and limited installation space, fixed-angle meters are often placed in positions that are unfavorable for reading. Operators need to bend over, look up, or turn sideways to read the data, which is not only inconvenient to operate, but may also lead to misreading of data due to the reading angle. In some special situations, such as high temperature, high pressure, or toxic environments, inconvenient reading postures can also increase operational risks.

[0004] Therefore, it is necessary to design an intelligent vortex flow meter with a flexibly adjustable meter head angle to solve the above problems. Utility Model Content

[0005] To address the shortcomings of the aforementioned technologies, this invention provides an intelligent vortex flow meter that solves the problems of fixed meter head angle and difficulty in reading in complex installation environments. It features easy adjustment and operation and wide applicability.

[0006] To solve the above technical problems, the technical solution adopted by this utility model is: an intelligent vortex flow meter, including a connecting pipe, a meter head located above the connecting pipe, and a flange, and also includes an angle adjustment mechanism. The meter head is connected to the angle adjustment mechanism through a telescopic rod. The angle adjustment mechanism is movably installed on the connecting pipe, and the angle of the meter head is adjusted by the angle adjustment mechanism.

[0007] The angle adjustment mechanism includes an upward-facing fixed base, a ball joint, and a locking assembly. The ball joint is movably disposed inside the fixed base, and the locking assembly is disposed on one side of the fixed base.

[0008] The locking assembly includes a locking ring and an adjusting knob. The locking ring and the fixed base are integrally formed, and the adjusting knob is detachably connected to the locking ring via a screw.

[0009] Preferably, the fixing seat is connected to the connecting pipe through the connecting seat, and the fixing seat is embedded in the connecting seat and connected to it by threads.

[0010] Preferably, one end of the telescopic rod is fastened to the meter head, and the other end is inserted into the base, which is connected to the spherical connector.

[0011] Preferably, the top of the spherical connector has a threaded rod formed in the vertical direction, and the bottom center of the base has a threaded hole. The spherical connector is threadedly connected to the base, and the threaded hole is connected to the center of the telescopic rod.

[0012] Preferably, the ball joint has a wire-passing channel inside, and a spiral cable protection tube is installed inside the wire-passing channel.

[0013] Preferably, a flow sensor is installed inside the connecting pipe. The flow sensor is electrically connected to the meter head via a wire, which passes through the connecting seat, the angle adjustment mechanism, the base, and the telescopic rod.

[0014] Preferably, flanges are welded to both ends of the connecting pipe.

[0015] This invention proposes an intelligent vortex flow meter. By setting an angle adjustment mechanism and using a ball joint, the meter head can be adjusted to multiple angles, which solves the problem of difficult reading of fixed-angle meter heads in complex installation environments and improves the convenience of operation and the accuracy of reading.

[0020] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1The intelligent vortex flow meter shown includes a connecting pipe 1, a meter head 2 located above the connecting pipe, and flanges 3. Flanges 3 are welded to both ends of the connecting pipe 1. It also includes an angle adjustment mechanism 4. The meter head 2 is connected to the angle adjustment mechanism 4 via a telescopic rod 7. The angle adjustment mechanism 4 is movably mounted on the connecting pipe 1, and the angle of the meter head is adjusted by the angle adjustment mechanism.

[0023] By setting an angle adjustment mechanism, the angle of the meter head can be adjusted, which not only facilitates reading and operation, but also avoids data misreading caused by reading angle problems.

[0024] Specifically, such as Figure 2 As shown, the angle adjustment mechanism 4 includes an upward-opening fixed seat 41, a ball connector 42, and a locking assembly. The ball connector 42 is movably disposed inside the fixed seat 41, and the locking assembly is disposed on one side of the fixed seat 41. A U-shaped notch is formed on one side of the fixed seat, and the locking assembly is disposed on the side opposite to the U-shaped notch.

[0025] By setting a spherical connector inside the fixed base and using a locking component, the spherical connector can rotate within the fixed base. After rotating to a suitable angle, the locking component can limit the spherical connector to prevent it from rotating, thus ensuring the stability of the meter during use.

[0026] Furthermore, the locking assembly includes a locking ring 43 and an adjusting knob 44. The locking ring 43 is integrally formed with the fixing base, and the adjusting knob 44 is detachably connected to the locking ring via a screw.

[0027] For ease of operation, two locking rings are symmetrically arranged on the side wall of the fixed base, with a gap between the two locking rings. The locking rings are integrally formed with the fixed base, and the horizontal center line between the two locking rings is on the same horizontal line as the horizontal center line of the fixed base.

[0028] Furthermore, one end of the adjusting knob is threaded into a hexagonal bolt. The hexagonal bolt passes through two locking rings and extends outward. To ensure that the hexagonal bolt does not detach from the locking rings, an internal thread is formed on the inner wall of one of the locking rings, so that the end of the hexagonal bolt does not detach from the locking ring. After the end of the hexagonal bolt passes through the two locking rings, it is threaded into the adjusting knob, thereby realizing the adjustment of the ball joint by the adjusting knob, ensuring that it can rotate and remain stationary after being rotated to the appropriate position.

[0029] When the angle needs to be adjusted, loosen the adjustment knob. The clamping force of the locking ring on the fixed seat will decrease, and the ball joint can rotate freely. After the angle is adjusted to the correct position, tighten the adjustment knob to push the two locking rings to move towards each other, so that the fixed seat clamps the ball joint and the angle is fixed.

[0030] By setting a locking component, the meter head can work stably after adjustment, and the ball joint can be rotated and adjusted even when it is not fully locked, which facilitates operation.

[0031] The locking assembly adopts a threaded locking structure, which is simple to operate and ensures that the meter head can stably maintain the current angle after being adjusted to the appropriate position, and will not shift due to vibration or other factors.

[0032] This invention uses an angle adjustment mechanism to adjust the meter head's angle, meeting reading requirements in different installation scenarios. In use, simply loosen the adjustment knob, adjust the meter head to the appropriate angle, and then tighten the adjustment knob to secure it; the operation is simple and quick.

[0033] Preferably, the fixing seat 41 is connected to the connecting pipe 1 through the connecting seat 5, and the fixing seat 41 is embedded in the connecting seat 5 and threadedly connected to it.

[0034] By setting a connecting seat, the angle adjustment mechanism is connected to the connecting pipe. For ease of operation, a groove with internal threads is set on the surface of the connecting seat, and an external thread is formed on the outer surface of the fixing seat. The fixing seat is embedded in the groove and threadedly connected to it.

[0035] Preferably, one end of the telescopic rod 7 is fastened to the meter head 2, and the other end is inserted into the base 6, which is connected to the spherical connector 42.

[0036] In order to adjust the height of the meter head, a telescopic rod is installed between the angle adjustment mechanism and the meter head. The height of the meter head can be adjusted by adjusting the telescopic rod.

[0037] Specifically, a fixed cylinder is formed on the base, and symmetrical grooves are formed on the inner wall of the fixed cylinder. Guide posts that match the grooves are formed on the outer wall of the telescopic rod. The telescopic rod is movably inserted into the inner cavity of the fixed cylinder, and an insertion hole is opened on the outer wall of the fixed cylinder. The telescopic rod is locked by a locking screw.

[0038] The guide column and slide groove work together to guide the raising and lowering of the telescopic rod. After the telescopic rod is pulled out, it is locked by the locking screw, thereby realizing the rapid adjustment of the gauge height.

[0039] Preferably, the top of the spherical connector 42 has a threaded rod 45 formed in the vertical direction, and the bottom center of the base 6 has a threaded hole. The spherical connector 42 is threadedly connected to the base 6, and the threaded hole is connected to the center of the telescopic rod.

[0040] For easy disassembly, a threaded rod is installed on the top of the ball connector. The threaded rod is connected to the center thread of the bottom surface of the base. At the same time, the telescopic rod, the fixed cylinder, and the threaded rod all have wire passages inside for the wires to pass through. The wires pass through the threaded holes and extend upwards along the center of the base into the telescopic rod until they are electrically connected to the meter head.

[0041] Preferably, the ball connector 42 has a wire-passing channel inside, and a spiral cable protection tube is installed inside the wire-passing channel.

[0042] A cable guide is provided to accommodate the wires connecting the meter head and the sensor inside the connecting tube, preventing exposed wiring. The cable protection tube is made of flexible stainless steel, which can flexibly deform as the ball joint rotates, protecting the internal wires from damage.

[0043] The built-in cable channel and spiral cable protection tube design ensure the safety of the wiring connection, avoid the impact of the wiring on the angle adjustment, and protect the wires from damage during repeated adjustments.

[0044] Preferably, a flow sensor 8 is installed inside the connecting pipe 1. The flow sensor is electrically connected to the meter head through a wire, which passes through the connecting seat, the angle adjustment mechanism, the base, and the telescopic rod.

[0045] A vortex generator is provided on one side of the flow sensor. When water passes through the vortex generator, a Karman vortex street is generated. The flow sensor measures the Karman vortex street.

[0046] The base and connector work together to connect the connecting pipe, angle adjustment mechanism, telescopic rod and meter head, enabling rapid assembly of the intelligent vortex flow meter.

[0047] Example 2

[0048] The difference between this embodiment and Embodiment 1 is that:

[0049] A waterproof sealing ring is installed at the connection between the meter head and the telescopic rod. Made of fluororubber, the sealing ring offers excellent sealing and temperature resistance, preventing moisture from entering the meter head and affecting the operation of electronic components. This waterproof sealing ring enhances the meter head's sealing performance, ensuring the flow meter functions properly in humid environments.

[0050] The purpose of this invention is to provide an intelligent vortex flow meter. By setting an angle adjustment mechanism between the connecting pipe and the meter head, when the angle needs to be adjusted, the adjustment knob is loosened, the clamping force of the locking ring on the fixed seat decreases, and the spherical connector can rotate freely. After the angle is adjusted to the correct position, the adjustment knob is tightened, pushing the two locking rings to move towards each other, so that the fixed seat clamps the spherical connector, thereby fixing the angle. The spherical connector is fixed by a threaded locking method, which is simple to operate, reliable in positioning, and can ensure that the meter head can stably maintain the current angle after adjustment, without angle deviation due to vibration or other factors.

[0051] The above embodiments are not intended to limit the present utility model, nor is the present utility model limited to the examples given above. Any changes, modifications, additions or substitutions made by those skilled in the art within the scope of the technical solution of the present utility model are also within the protection scope of the present utility model.
