Description

Technical Field

[0001] The invention belongs to the technical field of water quality monitoring, and in particular relates to a water quality monitoring pretreatment device. Background Art

[0002] In recent years, with the enhancement of people's environmental awareness, water quality testing has become more and more important. In order to understand the water quality of rivers in real time, my country has successively established water quality testing stations in various key rivers and lakes. The water stations detect the water environment quality and its pollution changes, providing important information for the protection, management and prevention of water pollution. However, the distance between large fixed water stations is far, which leads to a large distance between the separation points for collecting samples. Therefore, many monitoring devices installed on buoys are born, also known as floating water quality monitoring stations. Due to the high flow speed in river basins, the water flow will drive the sludge, aquatic plants and even domestic garbage in the rivers. Therefore, some pretreatment is required before sampling the water source.

[0003] The pretreatment method of existing floating water quality monitoring stations is generally to install a filter outside the sensor. When the filter is treated, stains on the filter are mostly cleaned by high-pressure water spraying. However, during cleaning, due to the distance between the high-pressure nozzles, when the nozzles are sprayed onto the filter, the area between the two nozzles is not cleaned thoroughly on the filter, which still affects the water quality.

[0004] In view of this, the present invention is proposed. Summary of the invention

In this configuration, the installation position and components of the fourth sliding mechanism are determined.

[0050] The implementation principle of a water quality monitoring pretreatment device in this embodiment is as follows:

[0051] First, when the water quality needs to be monitored, the water quality intelligent sensor is started. When the water quality intelligent sensor is started, the servo motor 201, the water pump 402 and the high-pressure pump 2043 can be controlled to operate (the water quality intelligent sensor controls the servo motor 201, the water pump 402 and the high-pressure pump 2043, which are all prior arts).

[0052] When the water pump 402 is running, the water in the inner cavity of the lower circular protective cylinder 103 can be pumped into the inner cavity of the upper circular protective cylinder 102 through the installation pipe 4021. At this time, the water can enter the inner cavity of the connecting pipe 203. Because the high-pressure pump 2043 is in operation, the water in the connecting pipe 203 can be pumped into the inner cavity of the water storage tank 205. The water in the water storage tank 205 can be sprayed out through the hose 2051 and the spray head 2052 provided at the water storage tank 205, and the filter screen provided at the lower circular protective cylinder 103 is pre-treated, thereby avoiding the accumulation of impurities to a certain extent.

[0053] When the servo motor 201 is started, the servo motor 201 can drive the rotating rod 2011 to rotate, and when the rotating rod 2011 rotates, it can drive the rectangular installation tube 202 to rotate, thereby driving the rectangular plug rod 2021 to rotate through the rectangular installation tube 202, because the rectangular plug rod 2021 is fixedly installed with a C-shaped connecting rod 2024, the connecting pipe 203 can be driven to rotate through the C-shaped connecting rod 2024, and the high-pressure pump 2043 can be driven to rotate through the connecting pipe 203;

[0054] When the high-pressure pump 2043 rotates, it can be assisted by the special-shaped slide groove 204, the sliding block 2041 and the connecting plate 2042 in the guide mechanism, so that the high-pressure pump 2043 can reciprocate up and down, thereby driving the connecting pipe 203 to reciprocate up and down. When the connecting pipe 203 reciprocates up and down, the rectangular plug-in rod 2021 can be pushed by the C-shaped connecting rod 2024 to move back and forth with the assistance of the first slide groove 2022 and the first slider 2023 in the third sliding mechanism provided in the rectangular installation cylinder 202;

[0055] At the same time, when the connecting pipe 203 reciprocates up and down and is in a rotating state, it can drive the fixed plate 3022 to rotate through the sliding rod 3024 and the second sliding groove 3023. Because the sliding rod 3024 slides on the second sliding groove 3023, the fixed plate 3022 can only rotate with the assistance of the first circular sliding groove 302 and the movable slider 3021, and will not move up and down. When the fixed plate 3022 rotates, it can drive the circular mounting plate 301 to rotate, and because The rotation speed of the circular mounting plate 301 is the same as that of the connecting pipe 203, and the connecting pipe 203 can move up and down, so the hose 2051 can be driven to change its angle with the assistance of the rotating rod 3012 in the rotating mechanism. When the angle of the hose 2051 changes, the angle of the spray head 2052 can be driven to change, so that the spray head 2052 can spray water more evenly to the filter screen on the lower circular protective cylinder 103, and the cleaning efficiency of the filter screen on the lower circular protective cylinder 103 is improved;

[0056] When the connecting pipe 203 moves up and down and is in a rotating state, it can drive the mounting rod 401 to rotate, and the rotation of the mounting rod 401 can drive the circular mounting plate 4011 to rotate and move up and down. When the circular mounting plate 4011 moves up and down and is in a rotating state, because the side wall of the circular mounting plate 4011 is provided with a second circular groove 4012, and a guide slider 4013 is slidably installed on the second circular groove 4012, and a mounting plate 4014 is fixedly installed on the guide slider 4013, and a moving rod 4023 is fixedly installed on the mounting plate 4014, and the moving rod 4023 is fixedly connected to the circular groove 4011. The circular movable plate 4024 is on the inner cavity of the installation pipe 4021, because the circular movable plate 4024 is slidably set, the guide slider 4013 will not move, so that when the annular mounting plate 4011 moves up and down, it can drive the guide slider 4013 to move up and down, thereby driving the mounting plate 4014, the moving rod 4023 and the circular movable plate 4024 to move up and down. When the circular movable plate 4024 moves downward, the circular hole opened on the filter plate 4022 can be cleaned by the guide rod 4025, which avoids the blockage of the filter plate 4022 to a certain extent.
