FIG. 2
TECHNICAL FIELD The present invention relates to a water sampling device, and in particular, to a depth adjustable and continuous water sampling device. The device is a sampling device for environment monitoring.
BACKGROUND The hydrological, chemical, and biological features differ at different water layers. Such differences are the important characteristics of water bodies and also the essential basic data for various studies. Therefore, accurate positioning in the water sampling process is the key to realizing sampling in a specific depth range. This is of great significance for obtaining water quality monitoring data for environmental investigation and remediation. For this purpose, the invention patents named "MULTI-DEPTH WATER QUALITY SAMPLER (CN204405374U)" and "WATER SAMPLE COLLECTOR WITH ADJUSTABLE SAMPLING DEPTH SCOPE (CN208568380U)" disclose devices that can be used to collect water samples at multiple depths. The devices can achieve accurate positioning and avoid water sample mixing. However, they have the disadvantages of cumbersome operations, small sampling volume, and repeated collections, which increases the workload, reduces the efficiency, and easily causes water disturbance. In addition, "AUTOMATIC DEVICE FOR SYNCHRONOUS SAMPLING AT WATER LAYERS (CN203376184U)" can achieve continuous sampling and overcome the shortcomings of repeated collections, but its adjustable stroke is small, and the support tube needs to be taken out each time the depth is adjusted.
SUMMARY Preferred embodiments of the present invention seek to provide a depth-adjustable and continuous water sampling device that can adjust the sampling depth easily and perform sampling efficiently without causing much water disturbance. According to an aspect of the present invention, there is provided a depth-adjustable and continuous water sampling device, comprising a sampling device fixed on a floating body, where the sampling device includes an automatic hose reel fixed on the floating body, a sampling hose with scales on the surface and coiled on the automatic hose reel, and a water pump fixed on the floating body and connected to one end of the sampling hose; the other end of the sampling hose passes over a fixed pulley and is connected to a suction head; and the fixed pulley is fixed on the floating body through a bracket. Preferably, the suction head is connected with a plumb through a sling; and preferably the suction head is a flat duckbill-shaped structure, with a filter screen fixed at its opening. In the above technical solution, the automatic hose reel is a mature product on the market, and its structure is not described herein. Compared with the prior art, the present invention has the following advantages due to the above technical solution: (1) The use of a hose reel to release the sampling hose allows easy and accurate adjustment of the underwater depth of the suction head without causing water disturbance. (2) Unlike the conventional devices that need to repeatedly take out the sampling container from the water, the present invention uses a water pump to continuously collect water samples, which can reduce the workload, improve sampling efficiency, and ensure sample information accuracy.
BRIEF DESCRIPTION OF DRAWINGS FIG. 1 is a schematic diagram of a structure of the present invention. FIG. 2 is a schematic structural diagram of a suction head of the present invention. In the figure, water pump 1, water sample collection container 2, floating body 3, plumb 4, suction head 5, sampling hose 6, bracket 7, fixed pulley 8, and automatic hose reel 9.
DETAILED DESCRIPTION The following describes the present invention in detail with reference to the accompanying drawings and specific examples. As shown in FIG. 1 and FIG. 2, a sampling device includes an automatic hose reel 9 fixed on a floating body 3, a sampling hose 6 with scales on the surface and coiled on the automatic hose reel, and a water pump 1 fixed on the floating body 3 and connected to one end of the sampling hose through a screwed pipe joint (not shown in the figure); the other end of the sampling hose 6 passes over a fixed pulley 8 and is connected to a suction head through another screwed pipe joint (not shown in the figure); the fixed pulley 8 is fixed on the floating body 3 through a bracket 7; and an outlet of the water pump 1 is connected to a water sample collection container 2 through a connecting pipe (not shown in the figure). The floating body 3 is a floating device with a bearing capacity, such as a boat, a raft, or a floating platform. The automatic hose reel 9 is a commercially available product. Its structure and working principle are well known to those skilled in the art, and are not described herein. To ensure that the suction head 5 can extend vertically into the water, the suction head is connected with a plumb 4 through a sling (not shown in thefigure). To collect water samples uniformly and avoid the formation of turbulence in the water layer, the suction head 5 uses a flat duckbill-shaped structure. To avoid sucking in debris, the suction head 5 has a filter screen (not shown in the figure) fixed at its opening. When in use, pull out the suction head 5 from one end of the automatic hose reel 9 and slowly extend it into the water. After the suction head 5 reaches a predetermined depth, lock the automatic hose reel 9. Then start the water pump 1 (manually or electrically) to collect water samples into the water sample collection container 2 until a required volume of water sample is collected. Throughout this specification and the claims which follow, unless the context requires otherwise, the word "comprise", and variations such as "comprises" and "comprising", will be understood to imply the inclusion of a stated integer or step or group of integers or steps but not the exclusion of any other integer or step or group of integers or steps. The reference in this specification to any prior publication (or information derived from it), or to any matter which is known, is not, and should not be taken as an acknowledgment or admission or any form of suggestion that that prior publication (or information derived from it) or known matter forms part of the common general knowledge in the field of endeavour to which this specification relates. While various embodiments of the present invention have been described above, it should be understood that they have been presented by way of example only, and not by way of limitation. It will be apparent to a person skilled in the relevant art that various changes in form and detail can be made therein without departing from the spirit and scope of the invention. Thus, the present invention should not be limited by any of the above described exemplary embodiments.
