[0024] Currently, there are various water sampling devices on the market, the most common of which is the rope sampling bottle. It has a simple structure and is easy to operate. However, although the rope sampling bottle can meet the basic water sampling needs, it still has significant drawbacks in practical applications. For example, it is very difficult to control the sampling depth of the sampling bottle. Generally, it can only rely on the personal experience of the staff to judge the sampling depth and then take the sample. However, this operation also causes a large error in the detection of water quality samples, which has a great impact on subsequent research and analysis.

[0025] Therefore, the design concept of this application is to design a device that can collect water samples at a fixed depth. This application adopts a floating mechanism and a height-controllable extraction steel pipe to accurately control the water sample collection depth. According to the survey requirements, the required height steel pipe can be used to collect water samples at the required depth.

[0026] like Figure 1As shown, this application provides a water sampling device for water conservancy surveys, including a rope connected to a floating mechanism, a support plate 3 connected to the floating mechanism, and a sampling steel pipe 5 detachably connected to the support plate 3. A filter ball 6 is connected to the inlet end of the sampling steel pipe 5, and a water outlet hose is connected to the outlet end of the sampling steel pipe 5. The water outlet hose is connected to a water pump, and the water pump is connected to a water outlet valve. The water pump and water outlet valve can be installed on the shore or on a boat. The filter ball 6 is made of stainless steel mesh and its function is to initially filter dead leaves, large particles of impurities, etc., to reduce sampling errors and prevent clogging of the sampling steel pipe 5 and the water outlet hose.

[0027] The floating mechanism includes a float 1, on which a support frame 2 is provided. The support frame 2 is connected to the bottom of the support plate 3. The float 1 is a solid foam float, which is inexpensive, durable and has great buoyancy. The float 1 and the support frame 2 can be connected by clamps or U-bolts. The support frame 2 is welded or threaded to the support plate 3.

[0028] The support frame 2 is equipped with a connecting ring 7, which is connected to a rope. The support frame 2 is welded or threaded to the connecting ring 7. In use, the rope is tied to the connecting ring 7, and after the other parts are installed, it is pushed into the water. After extraction, the floating mechanism is pulled to the shore or a boat by pulling the rope.

[0029] The support plate 3 is provided with a connecting sleeve 4, which is threadedly connected to the extraction steel pipe 5. The support plate 3 and the connecting sleeve 4 are welded or threadedly connected. In use, the extraction steel pipe 5 can be disassembled and replaced by screwing on the connecting sleeve 4.

[0030] Among them, at least one connecting sleeve 4 is provided; when multiple connecting sleeves 4 are designed, care should be taken to arrange them as evenly as possible. In this way, the support plate 3 can be kept more stable during use, that is, the extraction steel pipe 5 should be kept vertical for water sampling as much as possible, avoiding the extraction steel pipe 5 from tilting, which would cause errors in the water sampling height; when installing extraction steel pipes 5 of different heights, the longest one should be in the middle and the others on the side as much as possible. This is also more conducive to keeping the support plate 3 more stable and reducing errors in the water sampling height.

[0031] The extraction steel pipe 5, connecting sleeve 4, water outlet hose, water pump, and water outlet valve are in a one-to-one correspondence. One set of extraction steel pipe 5, connecting sleeve 4, water outlet hose, water pump, and water outlet valve can collect water samples at one depth. When water samples at different depths need to be collected, multiple sets of extraction steel pipe 5, connecting sleeve 4, water outlet hose, water pump, and water outlet valve need to be set up.

[0032] The extraction steel pipe 5 is detachably connected to the outlet hose; the outlet hose is detachably connected to the water pump; in use, the extraction steel pipe 5 and the outlet hose, and the outlet hose and the water pump are connected by quick connectors.

[0033] To use this device, first tie the rope to the connecting ring 7. Then, according to the required water sample depth, screw the extraction steel pipe 5 of the corresponding height onto the connecting sleeve 4 (when multiple depths are required, install the extraction steel pipe 5 according to the principle of the longest length in the middle and the other lengths on the sides). Use quick connectors to connect the extraction steel pipe 5 to the water outlet hose and the water outlet hose to the water pump. Then, put the assembled device into the water (at this time, the extraction steel pipe 5 is vertically inserted into the water). Plug in the power to start the water pump, open the water outlet valve, and the water sample will flow out from the water outlet valve. The staff can then collect it using sample bottles or other equipment.

[0034] The structure of this application is reasonably designed and easy to operate, enabling water sampling at different water depths and ensuring the originality and accuracy of the water samples.

[0035] Although the present invention has been described in detail with reference to the accompanying drawings and preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, those skilled in the art can make various equivalent modifications or substitutions to the embodiments of the present invention, and such modifications or substitutions should all be within the scope of the present invention. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should also be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
