Detailed Description
The following describes embodiments of the present invention in detail with reference to the accompanying drawings.
Referring to fig. 1 to 5, the present invention provides an ultrasonic flow detector, which includes a housing 1, wherein the housing 1 is a cavity with two open ends, two ends of the cavity are respectively connected with an air inlet 11 and an air outlet 12, and for facilitating air intake, an end of the air inlet 11 is designed to be arc-shaped; a guide plate 2 is arranged in the cavity, the guide plate 2 divides the cavity into at least two flow channels, the number of the flow channels is equal to the number of the guide plates 2 plus one, a group of ultrasonic detection modules 3 which are oppositely arranged are respectively arranged in each flow channel, a control main board 4 is arranged at the upper end of the shell 1, and the control main board 4 is connected with the ultrasonic detection modules 3 through electric wires; in this embodiment, in order to achieve the effect of convenient installation, an annular clamping groove 16 is arranged on the outer wall of the air outlet 12; in order to further achieve the effect of convenient installation, four hanging lugs 13 are arranged on the shell 1, through holes 14 are respectively arranged on each hanging lug 13, and a reinforcing rib 15 is arranged between the shell 1 and each hanging lug 13.
Example one
The utility model provides an ultrasonic flow detector, which comprises a shell 1, wherein the shell 1 is a cavity with two open ends, the two ends of the cavity are respectively connected with an air inlet 11 and an air outlet 12, and the end part of the air inlet 11 is designed into an arc shape for facilitating air inlet; a guide plate 2 is arranged in the cavity, the cavity is divided into two flow channels by the guide plate 2, a group of ultrasonic detection modules 3 which are oppositely arranged are respectively arranged in each flow channel, a control main board 4 is arranged at the upper end of the shell 1, and the control main board 4 is connected with the ultrasonic detection modules 3 through electric wires; an annular clamping groove 16 is formed in the outer wall of the air outlet 12; four hanging lugs 13 are arranged on the shell 1, a through hole 14 is respectively arranged on each hanging lug 13, and a reinforcing rib 15 is arranged between the shell 1 and each hanging lug 13; its theory of operation is that a set of ultrasonic detection module 3 frequency in a runner sets up to 500KHZ, the frequency of ultrasonic detection module 3 in another runner sets up to 200KHZ, ultrasonic detection module 3 in these two runners detects simultaneously, when the flow in the runner is large-traffic, 200 KHZ's ultrasonic module measurement accuracy can be some more, the measured value is more accurate, when being the low discharge in the runner, when measuring with 500 KHZ's ultrasonic module, the precision can be some more, so this design adopts dual-frenquency dual channel to go to measure the flow in the runner, can effectively avoid, the unstable inaccurate problem of detected value that causes of flow in the runner.
