Description

Technical Field

[0001] This utility model relates to the field of hydrological monitoring technology, and more specifically, to a float-type timed flushing device triggered by a liquid level switch. Background Technology

[0002] Existing horizontal ADCPs mostly employ a design where a sliding trolley drives the ADCP to move up and down into the water, allowing the ADCP probe to be submerged underwater for continuous flow velocity measurement. However, because the probe is constantly submerged in water and is relatively embedded within the protective cover, with the overall installation position close to the shore, the water flow velocity on the probe surface is relatively slow, creating a relatively small semi-enclosed space around it. This makes it prone to sediment accumulation and the attachment of planktonic plants and animals within the protective cover. At the same time, sand accumulation and wheel jamming are also prone to occur at the trolley pulleys. Utility Model Content

[0003] This invention aims to overcome the problems of floating mud accumulation and planktonic plant attachment that easily occur inside the protective cover when performing flow velocity measurement with a horizontal ADCP, as well as the problem of sand accumulation and wheel jamming at the trolley pulley. It provides a float-type liquid level switch triggered timed flushing device.

[0004] A float level switch triggered timed flushing device is installed on a horizontal ADCP device, including a float level switch, a time relay, a high-pressure water pump, and a first flushing pipe. The mechanical contacts of the float level switch are connected in series to the control circuit of the time relay, and the output contacts of the time relay are connected to the power supply of the high-pressure water pump. One end of the first flushing pipe is connected to the outlet of the high-pressure water pump, and the other end extends into the protective cover of the ADCP probe.

[0005] Furthermore, the horizontal ADCP device includes an ADCP probe, a protective cover, a mounting plate, a slide rail, and pulleys. The protective cover is placed on the outside of the ADCP probe and fixed to the mounting plate. The slide rail is located below the mounting plate. The pulleys are installed at the four corners of the bottom of the mounting plate and are adapted to the slide rail. The float level switch is located on the outside of the mounting plate. The high-pressure water pump is installed on the mounting plate.

[0006] Furthermore, it also includes a second flushing pipe, which is arranged in a one-to-one correspondence with the pulley. One end of the second flushing pipe is connected to the outlet of the high-pressure water pump, and the other end extends to the inside of the slide rail. The flushing direction of the second flushing pipe is towards the pulley.

[0007] Furthermore, the high-pressure water pump is located behind the protective cover, and the outlet of the high-pressure water pump is connected to an outlet pipe. Both the first flushing pipe and the second flushing pipe are connected to the outlet pipe.

[0008] Furthermore, both the first flushing pipe and the second flushing pipe are flexible hoses.

[0009] Furthermore, there are two first flushing pipes, and a horizontal through hole is provided on the front side of the protective cover. The two first flushing pipes enter the protective cover below the horizontal through hole.

[0010] Furthermore, a connecting rod is horizontally arranged on the mounting plate, the connecting rod is perpendicular to the slide rail and extends to the outside of the mounting plate, and the cable of the float level switch is tied to the connecting rod.

[0011] Furthermore, the time relay is installed on the shore.

[0012] Furthermore, the first flushing pipe and the second flushing pipe are bound together with the mounting plate.

[0013] Furthermore, the high-pressure water pump is bolted to the mounting plate.

[0014] Compared with the prior art, the beneficial effects of this utility model are:

[0015] The float level switch triggered timed flushing device of this utility model has its mechanical contacts connected in series to the control circuit of a time relay. The output contacts of the time relay are directly connected to the power supply of a high-pressure water pump. The outlet of the high-pressure water pump extends through the first flushing pipe to the position of the ADCP probe to be cleaned. The float level switch, the high-pressure water pump and the ADCP probe and protective cover are put into the water together. After the float level switch is put into the water, it floats. The time relay is energized, realizing automatic flushing with a large water pressure according to a preset cycle after entering the water, which can effectively reduce the intensity and frequency of manual cleaning.

[0016] The float level switch triggered timed flushing device of this utility model has a second flushing pipe, which is set to correspond one-to-one with the pulley. One end of the second flushing pipe is connected to the outlet of the high-pressure water pump, and the other end extends to the inside of the slide rail. The flushing direction of the second flushing pipe is towards the pulley, which flushes the pulley and effectively ensures the smooth movement of the trolley during the up and down movement. This reduces the risk of the trolley completely grinding against the pulley and derailing or jamming after the pulley jams. Attached Figure Description

Specifically, the outlet pipe includes a first connecting pipe 13, a first tee pipe 14, a second connecting pipe 15 connected to both ends of the first tee pipe 14, and a third connecting pipe 16 connected to the end of the second connecting pipe 15 away from the first tee pipe 14.
