Description

Water surface sampling device

Technical Field

The utility model belongs to the technical field of water quality monitoring, concretely relates to water surface sampling device.

Background

With the rapid improvement of the national environmental protection standard, the monitoring of the phenomena of stealing and leaking drainage of water body surface pollution is more and more important. The judgment of the pollution on the surface of the water body is a common measure for environmental protection in all social circles. At present, the method for judging the water body surface pollution mainly has two forms, firstly, whether the water body surface pollution exists is judged by observing the water body surface states such as color, impurities and the like on the water body surface, the judging method has high working intensity and low working efficiency, and the pollution condition cannot be objectively and accurately judged due to the influence of factors such as experience difference among individuals and the like, so that the monitoring result is inaccurate. The other form is that a microscopic identification counting method is adopted to judge the pollution condition of the water body surface, although the detection result is accurate, the method has the defects of very complicated processing steps, high cost, long time consumption and high requirement on the professional technical level of operators, and cannot be used for on-site rapid monitoring.

The Chinese patent with publication number CN108507625A discloses an intelligent monitoring platform and method for water plankton integrating the Internet of things, wherein a water taking unit in the platform comprises a sampling tube, a sampling pump and a water tank, and the water taking structure is simple but cannot inhibit the fluctuation of the surface of the water body, so that the fluctuation of the surface of the water body is large during detection, the acquired water body image is not clear, and the accuracy of a detection result is influenced.

SUMMERY OF THE UTILITY MODEL

For solving the fluctuation that current water quality monitoring device can't restrain the water body surface among the background art, the water image of gathering is unclear to lead to the unsafe problem of testing result, the utility model provides a water surface sampling device, concrete technical scheme is as follows.

The utility model provides a water surface sampling device, is including the floating water intake device, suction pump and the water tank that connect gradually, be equipped with the overflow board in the water tank, the overflow board will the water tank is separated into the surge bin and is taken photograph the storehouse, the surge bin is located the upper reaches in the storehouse is taken photograph to the fetch.

Through the structure, the utility model discloses a set up the overflow plate and restrain by the fluctuation of monitoring water surface to improve the definition of the water image of gathering and the accuracy of testing result. The upstream refers to the upstream of the flow direction of the water after entering the water tank.

Preferably, a water inlet is arranged on the buffer bin, and a water outlet is arranged on the illumination bin; one end of the water suction pump is connected with the floating water taking device, and the other end of the water suction pump is connected with the water inlet. Therefore, water entering the buffer bin firstly passes through the overflow plate and then enters the photographing bin, and the stability of the surface of the water entering the photographing bin is ensured. And the irradiated water body sample automatically flows back to a sampling point through a water outlet, so that sampling circulation is realized.

Preferably, a flow baffle plate is further arranged in the surge bin, a through hole is formed in the lower portion of the flow baffle plate, the height of the flow baffle plate is higher than that of the overflow plate, and the water inlet is located at the upstream of the flow baffle plate. Therefore, the impact force of water flow is effectively inhibited, and water flow in the water tank uniformly flows into the rear half part of the buffer bin after passing through the through hole.

Preferably, the floating water intake device is a floating decanter.

Preferably, the taking chamber is made of a material with high corrosion resistance and light transmittance.

Preferably, the taking chamber is made of an acrylic material.

Owing to adopted above technical scheme, compare with prior art, the utility model discloses a set up the overflow plate and restrain by the fluctuation of monitoring water surface to improve the definition of water image and the accuracy of testing result, and realized the automation of water surface pollution discernment, discernment work efficiency is higher, safe and reliable more. On the other hand, the flow baffle plate is arranged to effectively restrain the impact force of water flow, so that the water flow in the water tank uniformly flows into the rear half part of the buffer bin after passing through the through hole.

Detailed Description

The present invention will be described in further detail with reference to the accompanying drawings.

Referring to fig. 1, a water surface sampling device comprises a floating decanter 1, a water pump 2 and a water tank 3. An overflow plate 31 is arranged in the middle of the water tank 3, and the overflow plate 31 divides the water tank 3 into a buffer bin 32 and an illumination bin 33. The side wall of the buffer bin 32, which is far away from the overflow plate 31, is provided with a water inlet 321, the side wall of the photographing bin 33, which is far away from the overflow plate 31, is provided with a water outlet 331, one end of the water suction pump 2 is connected with the floating decanter 1 through a pipeline, and the other end of the water suction pump is connected with the water inlet 321 through a pipeline. The water outlet 331 is connected with a drain pipe 332, and the other end of the drain pipe 332 is connected to a sampling pool, so that the water body sample automatically flows back to a sampling point.

As shown in fig. 1 and 2, a flow baffle plate 322 is further disposed in the middle of the surge bin 32, and a through hole 323 is disposed at the lower portion of the flow baffle plate 322. The height of the baffle plate 322 is higher than the overflow plate 31.
