Description

Technical Field

[0001] This utility model relates to the field of river flow velocity and flow rate monitoring technology, specifically a flow velocity and flow rate monitoring device. Background Technology

[0002] Radar flow velocity monitoring equipment is one type of flow velocity and flow monitoring device. A radar flow meter is a non-contact, continuous, integrated flow monitoring device that measures flow velocity, water level, and flow rate. It employs radar planar microwave technology to measure the flow velocity and water level of a water body in a non-contact manner.

[0003] Radar flow velocity monitoring equipment mainly includes a radar flow meter, a power distribution box, a support column, and a support crossbar. The support column and support crossbar are crucial for the radar flow meter to be suspended above the river. When the radar flow meter malfunctions and needs to be repaired or replaced, personnel need to climb the support crossbar to disassemble and install the radar flow meter. Because the support crossbar supports the radar flow meter suspended above the river, the risk factor for personnel climbing the support crossbar to disassemble and install the radar flow meter is relatively high, making disassembly and assembly of the radar flow meter quite inconvenient.

[0008] Preferably, a rectangular groove communicating with the outside is provided on one side inner wall of the transmission cavity, and the connecting block is slidably installed in the rectangular groove.

[0009] Preferably, the active synchronizing wheel is equipped with a rotating shaft extending to the outside, and a handwheel is installed at one end of the rotating shaft extending to the outside.

[0014] Compared with the prior art, this utility model provides a flow velocity and flow rate monitoring device with the following beneficial effects: Through the cooperation of the active synchronous wheel and the driven synchronous wheel, this utility model allows the active synchronous wheel to be rotated by turning the handwheel when the radar flow meter needs to be repaired or replaced. This causes the synchronous belt to rotate and drive the connecting block to move vertically downward, so that the radar flow meter can follow the support crossbar to descend vertically. This allows maintenance personnel to repair or replace the radar flow meter without climbing, greatly reducing the risk factor of the maintenance process. Attached Figure Description

[0021] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0022] In the description of this utility model, unless otherwise stated, "a plurality of" means two or more; the terms "upper," "lower," "left," "right," "inner," "outer," "front end," "rear end," "head," "tail," etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. In addition, the terms "first," "second," "third," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0023] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0024] Please see Figure 1-5 A flow rate monitoring device includes a base 1 and a support column 2 mounted on the base 1. A transmission cavity 8 is provided in the support column 2. An active synchronous wheel 9 and a driven synchronous wheel 10 are rotatably mounted in the transmission cavity 8. A synchronous belt 11 is connected between the active synchronous wheel 9 and the driven synchronous wheel 10. A connecting block 12 is mounted on the synchronous belt 11. A movable block 4 is mounted on the connecting block 12. A support crossbar 5 is mounted on the movable block 4. A mounting frame 7 is provided at the bottom of the support crossbar 5. A docking block 14 is snapped into the mounting frame 7. A radar flow meter 6, model HD-RDF420, is connected to the bottom of the docking block 14. A rotating shaft 18 extending to the outside is mounted on the active synchronous wheel 9. A handwheel 3 is mounted on one end of the rotating shaft 18 extending to the outside.

[0025] By cooperating with the active synchronous pulley 9 and the driven synchronous pulley 10, when the radar flow meter 6 needs to be repaired or replaced, the active synchronous pulley 9 can be rotated by turning the handwheel 3, which in turn causes the synchronous belt 11 to rotate and drive the connecting block 12 to move vertically downward. This allows the radar flow meter 6 to descend vertically along with the support crossbar 5, so that maintenance personnel can repair or replace the radar flow meter 6 without climbing, greatly reducing the risk factor of the maintenance process.

[0026] Specifically, in this embodiment, a rectangular slide groove 13 communicating with the outside is provided on one side inner wall of the transmission cavity 8, and the connecting block 12 is slidably installed in the rectangular slide groove 13.

[0027] The direction of movement of the connecting block 12 can be restricted by setting the rectangular slide 13.

[0028] Specifically, in this embodiment, a section of the rotating shaft 18 extending to the outside is provided with multiple toothed grooves 19 along the circumferential direction. A protrusion 15 is provided on the support column 2. A slide rod 16 is slidably installed on the protrusion 15. A toothed block 17 that matches the toothed groove 19 is installed at the bottom of the slide rod 16. A return spring 20 is sleeved on the slide rod 16. One end of the return spring 20 abuts against the protrusion 15, and the other end of the return spring 20 abuts against the toothed block 17.

[0029] Through the cooperation of the slide bar 16, toothed block 17 and toothed groove 19, the toothed block 17 on the slide bar 16 can be kept pressed against the toothed groove 19 on the rotating shaft 18 by the return spring 20 under normal conditions, thereby achieving the purpose of locking the rotating shaft 18 and preventing the active synchronous wheel 9 from rotating under normal conditions, which would cause the height of the support crossbar 5 to change and affect the monitoring effect.

[0030] Specifically, in this embodiment, the docking block 14 and the mounting frame 7 are fixed by a movable pin 21. A fixing block 23 protrudes from one side of the mounting frame 7. A positioning pin 24 is slidably installed on the fixing block 23. The movable pin 21 has a socket 22 that matches the positioning pin 24.

[0031] The positioning pin 24 and the movable pin 21 work together to facilitate the connection and fixation of the docking block 14 to the mounting frame 7. When the radar flow meter 6 needs to be removed, the locking between the docking block 14 and the mounting frame 7 can be released by sequentially moving the positioning pin 24 and the movable pin 21, thereby achieving the purpose of quick disassembly and assembly.

[0032] Specifically, in this embodiment, the mounting frame 7 is provided with a mounting groove that is compatible with the docking block 14, and both the mounting groove and the docking block 14 have a T-shaped cross section.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
