Description

Technical Field

[0001] The utility model relates to the technical field of flow measurement, in particular to a flow measurement sensor system without weirs. 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 systems. When erected, the two sets of sensor systems are installed on the slope wall and bottom of the channel body respectively. When the water flows between the two sets of sensor systems, the sensor in the sensor device transmits the data to the microcomputer unit in the flow meter and calculates with the data collected by the probe of the flow meter;

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

[0004] On the one hand, it is necessary to dig weirs and grooves on the slope and bottom of the open channel to place the sensor carrier, which is difficult to construct and will cause structural damage to the open channel.

[0005] On the one hand, when the sensor is installed into the 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 be damaged due to the impact. Utility Model Content

[0006] In view of this, the problem to be solved by the utility model is to provide a flow metering sensor system that does not require weirs.

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

[0008] A sensor system for flow measurement without weir opening, wherein the sensor carrier is installed in a protective concave platform through a shock-absorbing rubber seat group;

[0009] The damping rubber seat assembly includes a damping rubber seat and a limiting ear. The sensor carrier is embedded in the damping rubber seat and its two ends extend to the outside of the damping rubber seat and are clamped with the limiting ear. The limiting ear is fixedly connected to the protective recess through a fastener.

[0010] The shock-absorbing rubber seat is an isosceles trapezoidal platform structure, and a U-shaped embedding groove is provided in the middle thereof.

[0011] The sensor carrier includes an embedding portion and a supporting portion;

[0012] The outer contour of the embedding portion is matched with the U-shaped embedding groove, and a through hole is opened on the supporting portion. The sensor fixing screw passes through the through hole and is threadedly connected with the sensor.

[0013] 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.

[0014] The limiting ear is in contact with the end of the shock-absorbing rubber seat through a top bolt.

[0015] The push bolt is of T-shaped structure, and the bolt rod of the push bolt is plugged into the limiting ear.

[0016] The fastener is a long screw.

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

[0018] (1) A protective concave platform is provided. The protective concave platform of the concrete structure is built on the slope wall and the bottom of the channel body. The sensor carrier is installed inside the protective concave platform through a shock-absorbing rubber seat assembly, thereby avoiding the digging of fixed weir grooves on the slope wall and the bottom of the channel body, thereby avoiding structural damage to the channel body.

[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 protective recessed platform, thereby preventing the sensor on the sensor carrier from being displaced due to the impact, protecting the sensor and preventing the sensor from being damaged due to the impact.

[0033] like Figures 1 to 5 As shown, the utility model provides a flow metering sensor system without opening a weir;

[0034] The sensor carrier 21 is installed in the protective concave platform 4 through the shock-absorbing rubber seat group. The protective concave platform 4 is a concrete structure, which is built on the slope wall and the bottom of the channel body, thereby avoiding the digging of fixed weir grooves on the slope wall and the bottom of the channel body, thereby avoiding structural damage to the channel body;

[0035] The shock absorbing rubber seat assembly includes a shock absorbing rubber seat 22 and a limiting ear 23. The sensor carrier 21 is embedded in the shock absorbing rubber seat 22, and its two ends extend to the outside of the shock absorbing rubber seat 22 and are clamped with the limiting ear 23. The limiting ear 23 is fixedly connected to the protective concave platform 4 through a fastener.

[0036] Through the design of the shock-absorbing rubber seat 22, during installation, if it hits the inner wall of the protective recess 4, it can play a buffering and energy release role to prevent the sensor 2 on the sensor carrier 21 from being damaged or 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 fasteners in this embodiment are long screws 27, which pass 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.

[0037] Specifically, the shock-absorbing rubber seat 22 is an isosceles trapezoidal platform structure, and a U-shaped embedding groove 221 is opened in the middle position; the sensor carrier 21 includes an embedding portion 211 and a supporting portion 212, and the outer contour of the embedding portion 211 is adapted to the U-shaped embedding groove 221. When embedded, the sensor carrier 21 is tightly connected to the shock-absorbing rubber seat 22 through the deformation of the rubber material. A through hole is opened on the supporting portion 212, and the sensor fixing screw 41 passes through the through hole and is threadedly connected to the sensor 2, thereby realizing the fixation of several of the sensors 2 on the sensor carrier 21.

[0038] 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 provided 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 several sensors 2, which facilitates the alignment of the sensors 2 on the slope wall and the bottom of the channel body.

[0039] Specifically, the limiting ear 23 is 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 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.

[0040] Specifically, 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.

[0041] Specifically, 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 .

[0042] Further, in this application, a flow meter system used in combination with a sensor system is also disclosed;

[0043] like Figure 6 and 7 As shown, the solar panel 11 of the flow meter 1 of the flow meter system 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;

[0044] 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.

[0045] 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 .

[0046] 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;

[0047] 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 .

[0048] 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.

[0049] 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 .

[0050] The working principle and working process of the utility model are as follows:

[0051] When installing the sensor carrier 21, first place the sensor carrier 21 in the protective recess 4. The design of the shock-absorbing rubber seat 22 plays a buffering and energy-releasing role when it hits the inner wall of the protective recess 4, 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.

[0052] 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.
