Description

Technical Field

[0001] The utility model relates to the technical field of flow measurement, in particular to a detachable sensing device for open-channel flow measurement. Background Art

[0002] Open-channel flow measurement equipment is a monitoring tool for measuring the fluid flow in open channels and the like, including a flowmeter and at least two groups of sensing devices. When installing, concave weir troughs are dug on the two side slopes of the channel body, and the two groups of sensing devices are symmetrically installed in the weir troughs on the slope walls. When the water flow passes between the two groups of sensing devices, the sensors in the sensing devices transmit data to the microcomputer unit in the flowmeter and calculate in cooperation with the data collected by the probes;

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

[0004] When installing the existing sensors, most of them are directly fixed in the weir trough by screws. After the measurement task of this stage is completed, for anti-theft and safety considerations, it is generally necessary to remove the whole device, and then install it again when the measurement task of the next time stage comes. In this way, it is necessary to drill holes in the weir trough multiple times, which not only increases the workload but also damages the structure of the weir trough. Summary of the Utility Model

[0005] In view of this, the problem to be solved by the utility model is to provide a detachable sensing device for open-channel flow measurement.

[0006] To solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A detachable sensing device for open-channel flow measurement includes a weir trough embedding box and a sensor carrier. Quick socket groups are inserted at both ends of the sensor carrier, and the quick socket groups are detachably connected to the weir trough embedding box.

[0008] The quick socket group includes a plug and a bottom plate. A U-shaped limiting groove is formed on the bottom plate, and threaded holes are opened at positions corresponding to the U-shaped limiting groove in the weir trough embedding box.

[0009] Sockets adapted to the plugs are formed at both ends of the sensor carrier.

[0010] Extension plates are formed on both sides of the box opening at the top of the weir trough embedding box.

[0011] A through groove corresponding to the sensor is formed on the lid of the weir trough embedding box.

[0012] A transverse strip groove is formed on the sensor carrier, and a hand-tightening screw passes through the transverse strip groove and is threadedly connected to the sensor.

[0013] The utility model has the following advantages and positive effects:

[0014] The sensor carrier loaded with sensors is detachably connected to the weir box through a quick socket group inserted at both ends. When performing measurement tasks, turn the fixing screw clockwise to connect the quick socket group with the weir box, so that the sensor carrier is fixed inside the weir box. After completing the measurement tasks, turn the fixing screw counterclockwise to separate the quick socket group from the weir box, and directly take out the sensor carrier from the weir trough. The weir box can be retained in the weir trough. When the measurement task is due at the next time stage, connect the quick socket group with the weir box again. In this way, it is not necessary to drill holes in the weir trough multiple times to install the sensor carrier. It only needs to connect or separate the sensor carrier and the quick socket group, which reduces the workload and does not cause structural damage to the weir trough. Description of the Drawings

[0026] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present utility model belongs. The terms used herein in the description of the present utility model are only for the purpose of describing specific embodiments, and are not intended to limit the present utility model. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0027] As Figures 1 to 2 shown, the present utility model provides a detachable sensing device for open channel flow measurement;

[0028] It includes a weir box 1 and a sensor carrier 21. A plurality of sensors 24 are installed on the sensor carrier 21 along the length direction of the sensor carrier 21. The width of the weir box 1 is adapted to the width of the weir, and thus it can be embedded into the weir. In this embodiment, it is fixed to the weir by the way of cement pouring in the weir.

[0029] At both ends of the sensor carrier 21, quick socket sets 3 are inserted. The two quick socket sets 3 are inserted opposite to each other at both ends of the sensor carrier 21. The quick socket set 3 is detachably connected to the weir trough embedded box 1. When the quick socket set 3 and the weir trough embedded box 1 are in the connected state, since the distance between the two quick socket sets 3 is fixed, the displacement of the sensor carrier 21 is restricted, so that the sensor carrier 21 is fixed in the weir trough embedded box 1 to perform the measurement task. When the quick socket set 3 and the weir trough embedded box 1 are in the separated state, the sensor carrier 21 can be directly taken out from the weir trough, and the weir trough embedded box 1 is retained in the weir trough. It can be installed again when the measurement task is carried out in the next time period. In this way, it is not necessary to punch holes in the weir trough multiple times to install the sensor carrier 21. It is only necessary to connect or separate the sensor carrier 21 and the quick socket set 3, which reduces the workload and does not cause structural damage to the weir trough.

[0030] As Figures 3 to 5 shown, specifically, the quick socket set 3 includes a plug 31 and a bottom plate 32. The plug 31 is arranged facing the length end of the sensor carrier 21, and the bottom plate 32 is fixed to the bottom of the plug 31. A U-shaped limit groove 33 is formed on the bottom plate 32. A threaded hole is opened in the weir trough embedded box 1 at a position corresponding to the U-shaped limit groove 33. The fixing screw 27 passes through the U-shaped limit groove 33 and is connected to the threaded hole, thereby realizing the fixation of the weir trough embedded box 1 and the quick socket set 3.

[0031] As Figures 3 to 6 shown, specifically, sockets 22 adapted to the plugs 31 are formed at both ends of the sensor carrier 21. Along the length direction of the sensor carrier 21, a damping strip groove 25 is formed at the bottom of the sensor carrier 21. The damping strip groove is used to increase the roughness when the plug 31 is connected to the socket 22, and prevent the sensor carrier 21 from deflecting when the plug 31 is inserted into the socket 22.

[0032] Specifically, extension plates 11 are formed on both sides of the box opening at the top of the weir trough embedded box 1. The weir trough embedded box 1 is embedded and installed in the weir trough, and the extension plates 11 are abutted against the slope walls on both sides of the weir trough, so that the bottom of the weir trough embedded box 1 can be suspended. When pouring cement, it can flow through the bottom of the trough embedded box 1, thereby increasing the contact area with the cement and improving the connection strength between the weir trough embedded box 1 and the weir trough.

[0033] Specifically, a through groove 13 corresponding to the sensor 24 is formed on the lid 12 of the weir trough embedded box 1. The lid 12 is used to block foreign objects from entering the inside of the weir trough embedded box 1. The design of the through groove 13 enables the sensor 24 not to be shielded.

[0034] A transverse strip groove 23 is formed on the sensor carrier 21. The hand-tightening screw 26 passes through the transverse strip groove 23 and is threadedly connected to the sensor 24. The design of the transverse strip groove 23 can not only fix the sensor 24 relative to the sensor carrier 21, but also adjust the elevation angle of the sensor 24 relative to the sensor carrier 21 to correspond to different measurement conditions and installation environments.

[0035] The working principle and process of the present utility model are as follows:

[0036] When it is necessary to install the sensor 24 for flow measurement, the hand-tightening screw 26 is passed through the transverse strip groove 23 and threadedly connected to the sensor 24. Then, the plug 31 of the quick socket group 3 is inserted into the socket 22 at both ends of the sensor carrier 21. After the sensor carrier 21 and the quick socket group 3 are placed in the weir trough embedding box 1, the fixing screw 27 is passed through the U-shaped limiting groove 33 and connected to the threaded hole in the weir trough embedding box 1 to fix the weir trough embedding box 1 and the quick socket group 3. Finally, the elevation angle of the sensor 24 relative to the sensor carrier 21 is adjusted according to the measurement conditions and installation environment so that the sensors 24 on both side slopes of the channel body are aligned, and then the hand-tightening screw 26 is tightened to fix the elevation angle position;

[0037] When disassembling, the fixing screw 27 is reversely screwed to separate the quick socket group 3 from the weir trough embedding box 1, and then the sensor carrier 21 is directly taken out, and the weir trough embedding box 1 remains in the weir trough.

[0038] The above has described the embodiments of the present utility model in detail, but the above content is only the preferred embodiments of the present utility model and cannot be considered as limiting the scope of implementation of the present utility model. All equivalent changes and improvements made within the scope of the present utility model should still fall within the scope covered by this patent.
