Detailed Description

The present invention is described in terms of specific embodiments, and other advantages and benefits of the present invention will become apparent to those skilled in the art from the following disclosure. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

As shown in fig. 1 and 2, the utility model provides a sampling device for surface water quality monitoring.

This sampling device includes kickboard 1, articulates bracing piece 2, the activity that sets up wire roller 3 on kickboard 1, leads and extends to haulage rope 4 and the sample bottle 5 of setting at haulage rope 4 end on kickboard 1 lower surface through wire roller 3 on kickboard 1.

The floating plate 1 is made of High Density Polyethylene (HDPE). The common floating plate 1 carrier generally selects a plastic foam plate or a net plastic foam plate with a frame made of wood (bamboo), but the foam is easy to generate secondary pollution, and the wood and the bamboo are rigid materials and are easy to break and rot. Therefore, consider that carrier material requires highly to the life cycle, the utility model discloses plan for use the novel carrier of High Density Polyethylene (HDPE) that bearing capacity is strong, this material chemical stability is reliable, the non-staining water, ageing resistance can the reinforce be convenient for construct and maintenance management. The novel high-density polyethylene carrier has the advantages of reasonable and moderate rigidity and flexible physical indexes, attractive appearance, light weight, large buoyancy, convenience in disassembly and assembly, compression resistance, collision resistance, temperature change resistance, 5-8-year service life, recyclability and the like. The floating plate 1 floats on the water surface and can provide bearing points of the water surface for the traction rope 4 and the sampling bottle 5 at the tail end.

In order to guide the floating plate 1 to a position far away from the water bank or the measuring ship accessories, it is preferable that the supporting rod 2 is a telescopic rod, and a winding roller 9 is arranged at the near end of the telescopic rod, and the winding roller 9 can combine the supporting rod 2 and the traction rope 4 together, so that the efficiency of taking up and paying off the line can be improved while simplifying the device.

The pulling rope 4 is wound on the winding roller 9, and the pulling rope 4 extends to the wire guide roller 3 at the far end of the supporting rod 2 along the axial direction of the supporting rod 2.

As a preferred embodiment: the lower end of the supporting rod 2 is provided with a U-shaped pushing frame 10, and two inner side walls opposite to the opening of the U-shaped pushing frame 10 are provided with connecting shafts 11 which are respectively and rotatably connected to two side ends of the floating plate 1.

The arrangement mode is that if the floating plate 1 is only supported by the support rod 2, the floating plate 1 is easy to rotate and displace if the water surface fluctuation is large because the hinged position of the floating plate 1 and the support rod 2 is point connection, and the appliance is easy to damage due to large friction between the floating plate 1 and the support rod 2. Therefore, the U-shaped push frame 10 is selected to convert the point connection between the floating plate 1 and the support rod 2 into line connection, and at the moment, the floating plate 1 is restrained on the line and is not easy to rotate.

Further, a plurality of water retaining convex strips 12 radially spreading along the floating plate 1 are arranged on the lower surface of the floating plate 1. The water blocking convex strips 12 can enable the floating plate 1 to be subjected to water pressure in the horizontal direction, and the floating plate is not easy to move on the water surface randomly.

The center of the floating plate 1 is provided with a through hole 6 penetrating to the water surface, a rotating shaft 7 is horizontally arranged on the through hole 6, and the wire guide roller 3 is movably sleeved on the rotating shaft 7 through a bearing 8. The wire guide roller 3 is used for guiding the retraction of the traction rope 4, reducing the friction force between the traction rope 4 and the side wall of the floating plate 1 and saving strength.

Because the setting mode of the sampling bottle 5 for detecting water samples has been disclosed in a plurality of existing documents, and does not constitute the focus of the design of the utility model, it is not repeated herein.

When in use, the following steps are followed:

step one, lofting: pushing the floating plate 1 to a position on the water surface needing water quality inspection by using the support rod 2, wherein the traction rope 4 is in a tightened state on the winding roller 9;

step two, sampling: the traction rope 4 is fed by the winding roller 9, so that the sampling bottle 5 below the traction rope 4 is sunk into water under the action of gravity, and sampling is finished;

step three, collecting samples: the sampling bottle 5 is lifted by the aid of the traction rope 4 in the original position of the floating plate 1 at the monitoring point until the sampling bottle 5 contacts with the lower surface of the floating plate 1, and then the floating plate 1 and the sampling bottle 5 are dragged to the front of an operator by the aid of the support rod 2.

The utility model discloses sampling device borrows and is regarded as the load point by 2 spacing kickboards 1 of bracing piece, extends to the farther position of bank of water with the place of quality of water sample, has improved the accurate degree of quality of water sample.

Although the invention has been described in detail with respect to the general description and the specific embodiments, it will be apparent to those skilled in the art that modifications and improvements can be made based on the invention. Therefore, such modifications and improvements are intended to be within the scope of the invention as claimed.
