Description

Technical Field

[0001] The utility model relates to the technical field of flow measurement, in particular to a sensor device for measuring water channel flow. 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 sensor devices. When erected, the two sets of sensor devices are installed on the slope wall and the bottom of the channel body respectively. When the water flows between the two sets of sensor devices, the sensors in the sensor devices 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 used:

[0004] 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, which will not only cause the sensor to be damaged by the impact, but also disrupt the preset sensor spacing and affect the subsequent sensor alignment corresponding to the slope wall or the bottom. Utility Model Content

[0008] 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.

[0009] Through holes are provided on the two side walls of the sensor carrier at positions corresponding to the limit grooves, and the sensor fixing screws pass through the through holes and are threadably connected to the sensor.

[0029] like Figures 1 to 5 As shown, the utility model provides a sensor device for measuring water channel flow;

[0030] The sensor carrier 21 is embedded in the shock absorbing rubber seat 22. Both ends of the sensor carrier 21 extend to the outside of the shock absorbing rubber seat 22 to be clamped with the limiting ears 23. The limiting ears 23 are connected to the fixing plate 26 with screw holes.

[0031] Through the design of the shock-absorbing rubber seat 22, during installation, if it hits the inner wall of the weir groove, it can play a buffering and energy release role to prevent the sensor 2 on the sensor carrier 21 from being displaced due to impact; the two groups of limiting ears 23 are stuck at both ends of the shock-absorbing rubber seat 22, and the long screws 27 pass through the through holes on the fixing plates 26 on both sides of the bottom of the limiting ears 23 and then connect to the channel body, thereby realizing the fixation of the sensor carrier 21 on the channel body.

[0032] Specifically, the sensor carrier 21 is a U-shaped structure, and the shock-absorbing rubber seat 22 is an isosceles trapezoidal platform structure, wherein a groove matching the outer contour of the sensor carrier 21 is provided in the middle thereof, and the sensor carrier 21 and the shock-absorbing rubber seat 22 are tightly connected through the deformation of the rubber material during embedding.

[0033] Specifically, 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, facilitating the alignment of the sensors 2 on the slope wall and the bottom of the channel body.

[0034] Specifically, through holes are opened on the two side walls of the sensor carrier 21 at positions corresponding to the limiting grooves 25 , and the sensor fixing screws 41 pass through the through holes and are threadedly connected to the sensors 2 , thereby fixing the sensors 2 on the sensor carrier 21 .

[0035] The limiting ear 23 is a square cylindrical structure, and a slot 231 corresponding to the wall thickness of the sensor carrier 21 is configured on the open end of the limiting ear 23 . The sensor carrier 21 is embedded in the slot 231 to achieve a fixed connection between the limiting ear 23 and the sensor carrier 21 .

[0036] The limiting ear 23 is installed on the fixing plate 26, and the limiting ear 23 abuts against the end of the shock-absorbing rubber seat 22 through the top bolt 42, and then the shock-absorbing rubber seat 22 is clamped on both sides of the shock-absorbing rubber seat 22 through the top bolt 42 to prevent the shock-absorbing rubber seat 22 from being displaced relative to the sensor carrier 21.

[0037] A push bolt support frame 43 is also vertically mounted on the fixing plate 26 , and the push bolt 42 is sleeved on the push bolt support frame 43 .

[0038] The push bolt 42 is of T-shaped structure, and the bolt rod of the push bolt 42 is plugged into the limiting ear 23 , thereby preventing the push bolt 42 from being separated when abutting against the limiting ear 23 and the shock-absorbing rubber seat 22 .

[0039] like Figure 6 to Figure 7 As shown, further, in this application, a flow meter device used in combination with a sensor device is also disclosed;

[0040] The solar panel 11 of the flowmeter 1 of the flowmeter device is installed on a ladder frame 12 of a V-shaped structure. One end of the ladder frame 12 is used to abut the slope wall of the channel body, and the other end of the ladder frame 12 is used to abut the bottom of the channel body. By designing that the two ends of the ladder frame 12 respectively abut the slope wall and the bottom of the channel body, the solar panel 11 is erected above the channel body. When the metering point needs to be replaced, the ladder frame 12 can be directly moved.

[0041] 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.

[0042] Specifically, the bottom of the extension 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 .

[0043] like Figure 8 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;

[0044] 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 .

[0045] 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.

[0046] 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 .

[0047] The working principle and working process of the utility model are as follows:

[0048] 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.

[0049] 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.
