Abstract
The utility model relates to an open channel flow ultrasonic measurement device for survey waste water flow. The utility model discloses an open channel, the open channel outside are equipped with the pond of stewing, and the open channel bottom is linked together through the connecting pipe with the bottom of the pool portion of stewing, stew that the pond top is fixed to be equipped with ultrasonic flowmeter, and make ultrasonic flowmeter's the probe orientation bottom of the pool face that stews. The utility model discloses according to U type pipe principle, channel flow rivers water level is equal the pond middle water level of stewing, through the ultrasonic flowmeter survey pond water level that stews, and then must go out more accurate waste water flow, when the pond middle water level is stewed to ultrasonic flowmeter survey, does not receive the influence of waste water impurity and suspended solid, can effectively improve measurement accuracy.
Description
Technical field
The utility model relates to a kind of open channel flow rate ultrasonic measuring device, for wastewater measurement flow.
Background technology
Wastewater flow refers to the amount by the waste water of particular surface in the unit interval.For any open channel freely flowed, between the degree of depth and flow velocity of water, there is a specific relational expression, whenever there is the specific degree of depth, always there is identical flow velocity.Therefore, if the flow velocity of known each degree of depth, the relational expression of the degree of depth-flow velocity can just be set up.
Ultrasonic flow meter is exactly utilize the degree of depth of ultrasonic measuring waste water in specific open channel, and then draws real-time wastewater flow by the degree of depth-flow velocity relation formula.Ultrasonic flow meter is a kind of untouchable instrument, it both can measure bigbore rate-of flow, also may be used for the measurement of the medium not easily contacting and observe, can solve other instrument can not the flow measurement problem of severe corrosive, non-conductive, radioactivity and inflammable and explosive medium.But when the floating things such as foam, impurity, garbage on water are more or the water surface turbulent larger time, ultrasound wave, because of its inherent characteristic, is difficult to penetrate floating thing or is subject to turbulent flow impact and makes test water level inaccurate, causing wastewater flow result to occur deviation.
Utility model content
Technical problem to be solved in the utility model is: provide the open channel flow rate ultrasonic measuring device that a kind of measuring accuracy is higher.
The technical scheme adopted for solving the problems of the technologies described above the utility model is: open channel flow rate ultrasonic measuring device, comprise open channel, standing pond is provided with outside open channel, be connected by connecting pipe bottom open channel with bottom standing pond, leave standstill above pond and be fixed with ultrasonic flow meter, and make the probe of ultrasonic flow meter towards bottom surface, standing pond.
Further: open channel bottom surface and bottom surface, standing pond are positioned at same level.
Further: connecting pipe one end is connected to open channel bottom center, the other end is connected to standing pond bottom center, and connecting pipe is symmetrical set.
Further: the probe of ultrasonic flow meter is positioned at standing pond bottom center in the projection of bottom surface, standing pond.
The beneficial effects of the utility model are: according to U-tube principle, and Open Channels current water level is equivalent leaves standstill pond middle water level, surely leaves standstill pool water level, and then draw wastewater flow more accurately by ultrasonic flow rate measurement.When ultrasonic flow rate measurement leaves standstill pond middle water level surely, be not subject to the impact of waste water impurity and suspension, effectively can improve measuring accuracy.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Parts, position and numbering in figure: 1-open channel, 2-leave standstill pond, 3-connecting pipe, 4-ultrasonic flow meter.
Embodiment
Below in conjunction with accompanying drawing, the utility model is described in further detail.
As shown in Figure 1, the utility model comprises open channel 1, is provided with standing pond 2 outside open channel 1, is connected bottom open channel 1 with bottom standing pond 2 by connecting pipe 3, leave standstill above pond 2 and be fixed with ultrasonic flow meter 4, and make the probe of ultrasonic flow meter 4 towards bottom surface, standing pond 2.
Preferably, open channel 1 bottom surface and bottom surface, standing pond 2 are positioned at same level; Connecting pipe 3 one end is connected to open channel 1 bottom center, the other end is connected to standing pond 2 bottom center, and connecting pipe 3 is symmetrical set; The probe of ultrasonic flow meter 4 is positioned at standing pond 2 bottom center in the projection of bottom surface, standing pond 2.Better can ensure measuring accuracy.
The utility model is according to U-tube principle, and open channel 1 circulating water flowing water position is equivalent leaves standstill pond 2 middle water level, is measured and leaves standstill pool water level, and then draw wastewater flow more accurately by ultrasonic flow meter 4.When ultrasonic flow meter 4 measures and leaves standstill pond 2 middle water level, be not subject to the impact of waste water impurity and suspension, effectively can improve measuring accuracy.
Adopt the comparative test result of the utility model and existing routine techniques as shown in the table.
From comparative test result, the utility model can provide wastewater flow data more accurately.
