Description

Technical Field

[0001] The utility model relates to the technical field of flow measurement, in particular to an ultrasonic open channel flow measurement device. Background Art

[0002] Open channel flow metering equipment is a monitoring tool for measuring fluid flow in an open channel or other channel. It includes a flow meter and at least two sets of sensors. When erected, the two sets of sensors are installed on the slope wall and bottom of the channel respectively. When the water flows between the two sets of sensors, the sensors transmit the data to the microcomputer unit in the flow meter and calculate with the data collected by the probe;

[0003] The existing open channel flow equipment still has the following defects when in use:

[0004] On the one hand, in order to increase the power endurance of flow meters and sensors, some metering equipment is also equipped with solar panels. When arranging the measurement points, the support rods of the solar panels are buried in the land near the canal. However, since the soil near the canal is relatively soft, it needs to be buried deeper. Moreover, when the metering point needs to be replaced, it needs to be dug out, which is very time-consuming and labor-intensive, and has poor portability.

[0005] On the other hand, when the sensor is installed in the fixed weir groove at the slope wall and the bottom, the sensor carrier is very likely to hit the inner wall of the weir groove, causing the sensor to shift and unable to align with the corresponding sensor at the slope wall or the bottom, thus affecting the measurement accuracy. Utility Model Content

[0006] In view of this, the problem to be solved by the utility model is to provide an ultrasonic open channel flow metering device.

[0007] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0008] An ultrasonic open channel flow metering device, wherein a solar panel of the flow meter is mounted on a ladder frame of a V-shaped structure, one end of the ladder frame is used to abut against the slope wall of the channel body, and the other end of the ladder frame is used to abut against the bottom of the channel body;

[0009] The sensor carrier is embedded in the shock-absorbing rubber seat, and two ends of the sensor carrier extend to the outside of the shock-absorbing rubber seat for clamping the limiting ears.

[0010] The ladder frame comprises a V-shaped main ladder and a strip-shaped extension ladder, the flow meter is fixed on the main ladder, and both ends of the main ladder are fixedly connected to the extension ladder through perforated channel steels and locking screws.

[0011] The bottom of the extension ladder is configured with fixing ears.

[0012] The solar panel support frame of the solar panel is a U-shaped structure, and the flip adjustment screws penetrate through both sides of the solar panel support frame and are threadedly connected with the solar panel.

[0013] The flow meter is installed between the solar panel support frame and the ladder frame. A plurality of arc-shaped through grooves arranged in a ring shape are opened on the bottom of the solar panel support frame. The rotating adjustment screw passes through the arc-shaped through groove and is threadedly connected to the flow meter.

[0014] The sensor carrier is a U-shaped structure, and a cover plate is clamped at the open end of the sensor carrier. The cover plate is provided with a limiting groove adapted to the sensor; the sensor is sleeved in the sensor carrier and plugged into the limiting groove.

[0015] The limiting ear is a square cylindrical structure, and a notch corresponding to the wall thickness of the sensor carrier is configured on the open end of the limiting ear.

[0016] The limiting ears are plugged into the fixing plate, and the fixing plates on both sides of the limiting ears are also provided with through holes corresponding to the long screws.

[0017] The advantages and positive effects of the utility model are:

[0018] (1) Through the V-shaped ladder frame design, when it is necessary to set up the solar panels, it is only necessary to place the two ends of the ladder frame against the slope wall and the bottom of the channel body respectively; when it is necessary to change the metering point, the ladder frame can be directly moved. The installation and change of points are relatively simple, and the main ladder and the extension ladder can be separated by twisting the locking screws, which reduces the space occupied during transportation and is very portable.

[0019] (2) The design of embedding the sensor carrier on the shock-absorbing rubber seat can play a buffering and energy-releasing role when it hits the inner wall of the weir groove, thereby preventing the sensor on the sensor carrier from being displaced due to the impact, protecting the sensor, and preventing the sensor from shaking and affecting the measurement accuracy.

[0031] like Figure 1 to Figure 2 As shown, the utility model provides an ultrasonic open channel flow metering device;

[0032] The solar panel 11 of the flow meter 1 is installed on a ladder frame 12 of a V-shaped structure, one end of the ladder frame 12 is used to abut against the slope wall of the channel body, and the other end of the ladder frame 12 is used to abut against the bottom of the channel body; through the design that the two ends of the ladder frame 12 abut against the slope wall and the bottom of the channel body respectively, the solar panel 11 is set up above the channel body, and when the metering point needs to be changed, the ladder frame 12 can be directly moved;

[0033] The sensor carrier 21 is embedded in the shock absorbing rubber seat 22. The width of the shock absorbing rubber seat 22 corresponds to the width of the inner wall of the weir groove. The design of the shock absorbing rubber seat 22 can play a buffering and energy release role when it hits the inner wall of the weir groove, thereby preventing the sensor 2 on the sensor carrier 21 from being displaced due to the impact.

[0034] Both ends of the sensor carrier 21 extend to the outside of the shock-absorbing rubber seat 22, and are used to connect the clamping limit ears 23 of the fastening component. The two groups of limit ears 23 are clamped at both ends of the shock-absorbing rubber seat 22. The fastening component also includes a long screw 27 and a fixing plate 26. The long screw 27 passes through the through holes on the fixing plate 26 on both sides of the bottom of the limit ears 23, thereby realizing the fixation of the sensor carrier 21 on the channel body.

[0035] Specifically, the ladder frame 12 includes a main ladder 121 with a V-shaped structure and an extension ladder 122 with a strip structure. The flow meter 1 is fixed on the main ladder 121. The two ends of the main ladder 121 are fixedly connected to the extension ladder 122 through a perforated channel steel 16 and a locking screw 17. When the metering point needs to be replaced, they can be disassembled and transported separately, and then assembled after arriving at the metering point.

[0036] Specifically, the bottom of the extended ladder 122 is configured with a fixing ear 18 , which is connected to the slope wall of the channel body after passing through the ear hole of the fixing ear 18 through an anchor screw, thereby improving the connection stability of the ladder frame 12 .

[0037] like Figure 3 As shown, specifically, the solar panel support frame 13 of the solar panel 11 is a U-shaped structure, and the flip adjustment screw 14 passes through both sides of the solar panel support frame 13 and is threadedly connected to the solar panel 11;

[0038] The tightness of the connection between the solar panel support frame 13 and the solar panel 11 is adjusted by turning the adjusting screw 14 forward and backward, so as to adjust the pitch angle of the solar panel 11 .

[0039] Specifically, the flow meter 1 is installed between the solar panel support frame 13 and the ladder frame 12. The bottom of the solar panel support frame 13 is provided with a plurality of circularly arranged arc grooves 133. The rotating adjustment screw 15 passes through the arc grooves 133 and is threadedly connected to the flow meter 1.

[0040] The tightness of the connection between the solar panel support frame 13 and the flow meter 1 is adjusted by rotating the adjusting screw 15 forward and backward, so as to adjust the rotation angle of the solar panel 11 .

[0041] like Figures 4 to 6 As shown, specifically, the sensor carrier 21 is a U-shaped structure, and a cover plate 24 is clamped at the open end of the sensor carrier 21, and a limiting groove 25 adapted to the sensor 2 is opened on the cover plate 24; the sensor 2 is mounted in the sensor carrier 21 and plugged into the limiting groove 25, thereby achieving the same angle orientation of a plurality of the sensors 2, which facilitates the alignment of the sensors 2 on the slope wall and the bottom of the channel body.

[0042] Specifically, the limiting ears 23 are of a square cylindrical structure, and a slot 231 corresponding to the wall thickness of the sensor carrier 21 is constructed on the open end of the limiting ears 23 . The two groups of limiting ears 23 are designed to face each other and are connected to the two ends of the sensor carrier 21 through the slot 231 .

[0043] Specifically, the limiting ear 23 is installed on the fixing plate 26. Since the shock-absorbing rubber seat 22 has a certain thickness, the fixing plate 26 plays a role in raising the limiting ear 23, so that the limiting ear 23 and the sensor carrier 21 are in the same horizontal plane.

[0044] The working principle and working process of the utility model are as follows:

[0045] When installing the solar panel 11, it is only necessary to place one end of the ladder frame 12 against the slope of the canal body and the other end of the ladder frame 12 against the bottom of the canal body, so that the solar panel 11 can be set up above the canal body, and then connected to the slope of the canal body by passing the anchor screws through the ear holes of the fixing ears 18;

[0046] When the metering point needs to be replaced, the ladder frame 12 can be directly moved after the anchor screws are removed. The main ladder 121 and the extension ladder 122 can also be separated by twisting the locking screws 17 to reduce the space occupied during transportation;

[0047] When installing the sensor carrier 21, first place the sensor carrier 21 in the weir groove. The design of the shock-absorbing rubber seat 22 plays a buffering and energy-releasing role when it hits the inner wall of the weir groove, thereby preventing the sensor 2 on the sensor carrier 21 from being displaced due to impact. The two groups of limiting ears 23 are clamped at both ends of the shock-absorbing rubber seat 22, and long screws 27 are passed through the through holes on the fixing plates 26 on both sides of the bottom of the limiting ears 23, thereby realizing the fixation of the sensor carrier 21 on the channel body.

[0048] The above embodiments of the utility model are described in detail, but the above contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of the utility model should still fall within the scope of this patent.
