Technical field

The invention relates to a water instrument fixing device, and to a water quality deepening in-situ monitoring system using the device.

Background technique

With the development of society, environmental issues, especially natural water quality monitoring and integrated water management, are particularly important. Through regular monitoring of relevant pollutants and pollution factors in natural waters, we can understand the causes and sources of pollution of the water environment, and can conduct a series of comprehensive identification of related causes and sources of pollutants. The water environment is evaluated and evaluated. These can provide corresponding support for the prevention and control of pollution, water environment pollution, and the formulation of water environment standards. The specific type and working mechanism of the water quality monitoring structure are closely related to the accuracy and efficiency of the monitoring data obtained.

The traditional water quality monitoring structure and its drawbacks are as follows:

It is particularly difficult to perform manual sampling under severe meteorological conditions such as high winds, large waves and rapid current conditions, and the sampled data is not real-time, the experimental error is large, and the degree of automation is high. not tall;

2, pump station type monitoring structure: the use of pumps to pump the sampling water to shore, to achieve monitoring. This monitoring method invisibly changes the water quality parameters of the real water quality during the obtained water sample process, such as turbidity, dissolved oxygen, temperature and other water parameter elements, which are deviated from the real and objective water quality parameters, and are non-in situ monitoring. Kind of monitoring method. The suction water quality pipeline is complicated to set up, and the possibility that the pipeline freezes in the case of freezing rain and snow weather should be considered, and the reliability of the pump body decreases as the working time increases, and there may be a large deviation such as monitoring data. The overall structural redundancy maintenance cost is relatively high; another limitation is that the water station monitoring structure is particularly difficult to achieve water quality monitoring of the 50 cm water layer below the water meter. In other words, it is difficult to achieve deep sampling;

3. Buoy type monitoring structure: The buoy type monitoring structure is effective for monitoring the water quality of deep water system, but it is not suitable for water quality monitoring in shallow waters with large annual water level difference, and its manufacturing cost and maintenance cost are relatively high. In addition, the buoy type monitoring structure is not suitable for water quality monitoring in the waterway area of the ship, and the equipment equipped with the monitoring instrument of the buoy is relatively poor in extension, and is not suitable for monitoring instruments such as horizontal, vertical, and inclined installation modes;

4. Automatic depth monitoring structure: the detection instrument is put into the water body, and then the position signal of the monitoring instrument in the water body is fed back to the winch automatic settlement compensation system on the water surface through various sensors, thereby realizing the real-time monitoring of the depth; The characteristic of the monitoring structure is that the precision of the monitored deep-structured instrument is too high, the maintenance specialization degree is high, and the manufacturing cost is high.

Embodiment 1

As shown in FIG. 1 , the embodiment discloses a water instrument fixing device, which comprises a column 2 and a pontoon 4 . The column 2 is vertically installed deep into the water, and the pontoon 4 is sleeved on the column 2 and can be lifted along the column 2 mobile. The column 2 is fixed, and the pontoon 4 can be moved up and down along the column 2 as needed. In the technical solution of the embodiment, the preferred structure for satisfying the movement coordination of the column 2 and the pontoon 4 is as follows:

The pontoon 4 is provided with a through hole 10, and the upright 2 is bored in the through hole 10. The pontoon 4 is sleeved by the through hole 10, and the column 2 forms a movement constraint of the pontoon 4, so that the pontoon 4 moves up and down along the column 2 under the action of an external force. In design, the diameter (diameter) of the through hole 10 is larger than the diameter of the column 2, and a large gap is matched between the two. When the floating box floats up and down with the wave, the inner wall of the through hole is smashed to the outer wall of the column, so that there is no biological adhesion between the two. Possibilities, whether it is a softer algae plant or a smaller shellfish, can be disintegrated due to mechanical friction or mechanical squeezing without biofouling.

The fixing device in the technical solution of the embodiment is used for the fixed depth water quality monitoring instrument, and the water quality monitoring instrument needs to communicate the collected data through the cable and the outside world, in order to avoid the cable winding and knotting, the pontoon 4 is required to be along the edge. In the process of lifting and lowering the column 2, the column 2 cannot be rotated. In order to solve the technical problem, the hole of the through hole 10 of the present application is provided with an anti-rotation groove 12, and the column 2 is provided with an anti-rotation slider 14 When the column 2 is bored in the through hole 10, the anti-rotation slider 14 is restrained in the anti-rotation groove 12. The anti-rotation slider 14 and the anti-rotation groove 12 cooperate to prevent the pontoon 4 from rotating about the column 2 during the lifting movement of the column 2.

Further, at least two anti-rotation grooves 12 are disposed on the hole wall of the through hole 10, and each of the anti-rotation grooves 12 on the column 2 is provided with an anti-rotation slider 14, and the column 2 is pierced through the through hole. In the case of 10, the anti-rotation sliders 14 are constrained in the respective anti-rotation grooves 12 one by one. As shown in FIG. 3, in the technical solution of the embodiment, three anti-rotation slots 12 are preferably disposed, and three anti-rotation sliders 14 are disposed, and each of the anti-rotation sliders 14 is constrained in the respective anti-rotation slots 12. The cooperation of the plurality of anti-rotation sliders 14 and the anti-rotation groove 12 can uniformly restrain the force, and the pontoon 4 is prevented from tilting during the lifting movement, and is always floating smoothly on the water body.

Under the action of the buoyancy of the water body, the pontoon 4 floats on the water body. In order to fix the instrument, the pontoon 4 needs to adjust the depth in the water body as needed.

The air pipe 8 is used to intake air into the pontoon 4 or to discharge the gas in the pontoon 4 so that the air pressure in the pontoon 4 can be adjusted. The depth of the pontoon 4 in the water body is adjusted by adjusting the weight of the pontoon 4 by introducing water into the pontoon 4 or discharging the water in the pontoon 4, for example, the greater the weight of the pontoon 4, The greater the depth of positioning in the body of water; the opposite, the smaller. In order to accurately locate the depth of the pontoon 4, in the technical solution of the embodiment, the inside of the pontoon 4 is preferably designed as a sealed environment. When water is introduced into the pontoon 4 or the water inside is discharged, the air tube 8 needs to be synchronously adjusted. The air pressure in the pontoon 4 allows the water in the pontoon 4 to be discharged or the water inside thereof to be discharged smoothly. For example, while water is being supplied into the pontoon 4, the air pressure in the pontoon 4 needs to be lowered, so that the water inlet operation can be smoothly performed.

In the technical solution of the embodiment, the specific shape of the pontoon 4 is not constrained, and may be a cylindrical structure, a multi-faceted prism structure, etc., and the specific structure can be flexibly adjusted according to actual use conditions, for example, flexible adjustment according to the result of the instrument to be fixed, according to The number of instruments that need to be fixed is flexibly adjusted, and so on.
