Detailed Description

The present utility model will be described in further detail with reference to specific examples so as to more clearly understand the present utility model by those skilled in the art.

It should be noted that the terms "mounted," "connected," and "connected" are to be construed broadly, and may be, for example, fixedly connected, detachably connected, or integrally formed, unless otherwise specifically indicated and defined. The specific meaning of such terms in this patent will be understood by those of ordinary skill in the art as the case may be.

An anti-algae bow float flowmeter, as shown in figures 1-8, comprises a shading slag discharging cylinder 2 and a bow float 5;

two ends of the shading and deslagging cylinder 2 are respectively clamped with a fixing head 1, the fixing heads 1 are used for being communicated with a pipeline to be tested, a coaxial flowmeter cylinder body 3 is rotatably arranged in the shading and deslagging cylinder 2, a coaxial square sliding shaft 4 is arranged in the flowmeter cylinder body 3, the square sliding shaft 4 is fixedly connected with the shading and deslagging cylinder 2, the bow-shaped floater 5 penetrates through a through hole matched with the square sliding shaft 4, the bow-shaped floater 5 is sleeved on the square sliding shaft 4 in a sliding mode through the through hole, the flow meter barrel 3 is a transparent barrel, metering scales 7 are marked on the side wall of the flow meter barrel 3, and an observation hole 6 is formed in the side wall of the shading slag discharging barrel 2.

In this embodiment, the shading and slag discharging cylinder 2, the flow meter cylinder body 3 and the square sliding shaft 4 are coaxially arranged, and the shading and slag discharging cylinder 2 and the flow meter cylinder body 3 are in sealing connection, so that fluid cannot flow into a gap between the shading and slag discharging cylinder 2 and the flow meter cylinder body 3.

The fixed head 1 is used for being communicated with a pipeline to be measured, and fluid to be measured is provided for metering through the pipeline to be measured. For example, as shown in fig. 1, the fluid to be measured flows into the lower end part of the shading and deslagging cylinder 2 through the lower end of the fixing head 1, then flows into the inside of the flowmeter cylinder 3 from the lower end opening of the flowmeter cylinder 3, then flows into the upper end part of the shading and deslagging cylinder 2 from the upper end opening of the flowmeter cylinder 3, and finally flows out from the upper end of the fixing head 1. When fluid flows through the bow-shaped floater 5, the bow-shaped floater 5 floats under the action of buoyancy, and the bow-shaped floater 5 is sleeved on the square sliding shaft 4 in a sliding manner, so that the bow-shaped floater 5 can float up and down stably, and then the flow of the fluid can be read through the scale corresponding to the metering scale 7.

The projection of the arc-shaped floater 5 on the horizontal plane is arc-shaped, so that an annular gap between the arc-shaped floater 5 and the flowmeter barrel 3 is in an irregular shape, namely, a part of gap is arc-shaped, the area of the part of arc-shaped gap is larger, and scum 9 such as algae can be accommodated to pass through the gap, and when scum blockage occurs in the annular gap between the flowmeter barrel 3 and the arc-shaped floater 5, the square sliding shaft 4 is fixedly connected with the shading slag discharging barrel 2, namely, the shading slag discharging barrel 2 can be rotated to drive the arc-shaped floater 5 to synchronously rotate, so that scum 9 can be discharged from the arc-shaped gap between the arc-shaped floater 5 and the flowmeter barrel 3, and the problems that the flow meter is blocked, the floater is blocked and cannot be metered are effectively solved.

However, when the light shielding slag discharging cylinder 2 is rotated, the flow meter cylinder 3 may be driven to rotate synchronously, so that the bow float 5 and the flow meter cylinder 3 cannot rotate relatively. In order to avoid the above-mentioned problem, in this embodiment, the observation hole 6 has been seted up on the shading sediment section of thick bamboo 2 lateral wall, the observation hole 6 not only can be used for the staff to observe inside fast the measurement scale 7, can also be convenient for the staff pass through the observation hole 6, adopts modes such as manual pressing, fixes inside flowmeter barrel 3 for flowmeter barrel 3 can't rotate, then slowly rotate the outside shading sediment section of thick bamboo 2 can. The shading slag discharging barrel 2 can be selectively fixed, the inside of the flow meter barrel 3 is stirred through the observation hole 6, so that the flow meter barrel 3 rotates, the bow-shaped floater 5 and the flow meter barrel 3 can also rotate relatively, and then the slag 9 can be discharged from a bow-shaped gap between the bow-shaped floater 5 and the flow meter barrel 3.

In order to prevent the flow meter cylinder 3 from generating algae or other impurities, in this embodiment, the light-shielding slag discharging cylinder 2 is an opaque cylinder. This isolates most of the light so that it cannot impinge on the flowmeter barrel 3.

Because the side wall of the shading slag discharging barrel 2 is provided with the observation hole 6, part of light can pass through the observation hole 6 to irradiate the flowmeter barrel 3. In order to solve the above problem, in this embodiment, a light shielding patch 8 is disposed on the side wall of the flow meter barrel 3, and the light shielding patch 8 is adapted to the observation hole 6. The shading paste 8 can isolate part of light, and when the shading paste 8 rotates to be opposite to the observation hole 6, the light can be prevented from penetrating through the observation hole 6 to irradiate on the flowmeter barrel 3. Therefore, the shading slag discharging barrel 2 is matched with the shading paste 8, so that the effect of completely isolating light can be achieved.

The observation hole 6 may be a bar-shaped hole, so that a worker can observe the metering scale 7.

In this embodiment, the square sliding shaft 4 penetrates through the flowmeter cylinder 3, and the square sliding shaft 4 is fixedly connected with the shading slag discharging cylinder 2 through a steel wire. The steel wires are slim, so that the blocking effect on the fluid can be reduced, and the influence on the flow of the fluid is avoided.

In this embodiment, the lateral wall at the two ends of the flow meter barrel 3 is provided with external threads, the inner side wall of the shading slag discharging barrel 2 is provided with internal threads matched with the external threads, and the lateral wall at the two ends of the flow meter barrel 3 is in rotational threaded connection with the inner side wall of the shading slag discharging barrel 2. The outer side walls of the two ends of the flowmeter cylinder body 3 are in sealing threaded connection with the inner side walls of the shading and deslagging cylinder 2, so that fluid can be prevented from flowing into a gap between the shading and deslagging cylinder 2 and the flowmeter cylinder body 3.

In this embodiment, the fixing head 1 is fixed to the pipe to be tested by bonding. The bonding and fixing mode is simple, and the fixing efficiency is high.
