Description

Technical Field

[0001] The present invention belongs to the technical field of river and lake water sampling, and particularly relates to a river and lake water sample collector. Background Art

[0002] The main manifestations of water pollution include heavy metal pollution, organic pollution, fertilizer and pesticide pollution, etc. We should strengthen the monitoring and research of river and lake water quality to provide effective data support for the treatment of polluted water bodies. Therefore, it is necessary to sample river and lake water.

[0003] According to patent number: CN202220480485.9, an automatic sampler for water quality detection is disclosed, which solves the problem that when the sampling bottles currently on the market are used, impurities in the water easily flow into the sampling bottle from the bottle mouth along with the water, and it is inconvenient to sample the extended water quality. The sampler includes a sampling bottle, the top of the sampling bottle is threadedly connected to a bottle cap, and a shell is fixedly installed on the top of the bottle cap, a number of external openings are evenly opened at the bottom of the outer wall of the shell, a fixing ring is fixedly installed in the middle position of the top of the shell, and a connecting rope is fixedly connected to the fixing ring. The utility model can block impurities in the water when the sampling bottle is sampling water quality, and the sampling bottle can sample water quality at different depths.

[0004] In the above patent, the connecting rope needs to be held manually to slowly sink the sampling bottle into the water. Since the interior of the sampling bottle is a hollow cavity, it is difficult for the sampling bottle to be submerged in water. Even if it can be submerged in water, the first water sample to enter the sampling bottle is the water on the surface of the water body. At the same time, the sampling point is close to the shore, the sample is single, and the test results are not rigorous enough. Utility Model Content

[0005] In response to the shortcomings of the existing technology, the purpose of the present invention is to provide a river and lake water sample collector. The sampling personnel only need to stand on the shore to sample the sampling points far away from the shore. During the sampling process, it can ensure that the water body at the sampling depth is sampled to ensure the accuracy of the water sample.

[0006] The purpose of this disclosure can be achieved through the following technical solutions:

[0007] A river and lake water sample collector includes a sampling bottle, a water inlet is provided at the upper end of the sampling bottle, a bottle plug is provided in the water inlet, a first traction rope is fixedly connected to the bottle plug, the sampling bottle is detachably installed in a steel cage, a second traction rope is fixedly connected to the upper end of the steel cage, the first traction rope and the second traction rope pass through the inner rings of two hanging rings, and the two hanging rings are provided at both ends of a telescopic rod.

[0008] The above technical solution, its principle and technical effects:

[0009] When collecting water samples from rivers and lakes, the staff stands on the shore, adjusts the length of the telescopic rod according to the required distance between the sampling point and the shore, and drops the steel cage together with the sampling bottle to the sampling point. By lowering the pitch angle of the telescopic rod, the steel cage together with the sampling bottle are submerged in water under the weight of the telescopic rod. The sampling depth is controlled by controlling the pitch angle of the telescopic rod. At this time, the staff pulls the first traction rope to open the bottle stopper, and water flows in from the water inlet. When the water fills the sampling bottle, the second traction rope is pulled to pull the steel cage together with the sampling bottle out of the water. After the water sample reaches the shore, the steel cage is opened, the sampling bottle is taken out, and the bottle cap is plugged in. The water sample collection is completed.

[0010] The peripheral side of the steel cage is surrounded by a filter screen.

[0011] One end of the telescopic rod away from the sampling bottle is rotatably connected to a support, wherein a fastening bolt and nut are provided at the connection between the telescopic rod and the support.

[0012] The support is rotatably connected to two hand wheels on its circumferential side, the first traction rope is fixedly connected to one of the hand wheels, and the second traction rope is fixedly connected to the other hand wheel.

[0013] The lower end of the support is rotatably connected to a disc, and the lower end of the disc is fixedly connected to at least three anchor rods.

[0014] The top end of the support is fixedly connected with a circular angle plate, and the rotation point between the telescopic rod and the support is located on the axis of the circular angle plate.

[0015] The telescopic rod is provided with length scale lines.

[0016] The second traction rope at the upper end of the steel cage is fixedly connected with floats of different colors distributed at equal distances.

[0017] The nouns, conjunctions or adjectives involved in the above technical solution are explained as follows:

[0018] A fixed connection is a connection in which parts or components are fixed without any relative movement. There are two types of connections: detachable and non-detachable.

[0019] (1) A removable connection is a method of fastening components together using screws, splines, wedge pins, etc. This type of connection allows for disassembly during maintenance without damaging the components. However, the connectors used must be of the correct specifications (e.g., length of bolts, keys, wedge pins) and properly tightened.

[0020] (2) Non-detachable connections mainly refer to welding, riveting, and tenoning. Since they require forging, sawing, or oxygen cutting to disassemble during repair or replacement, spare parts generally cannot be reused. At the same time, when making connections, attention should be paid to workmanship quality, technical inspection, and remedial measures (such as calibration, polishing, etc.).

[0021] A threaded connection refers to a detachable connection in which the connected parts are connected together using a threaded part (or the threaded part of the connected parts).

[0022] A sliding connection is when two objects are in contact but not fixed and can slide relative to each other.

[0023] A rotational connection is a connection between parts that allows the parts to rotate relative to each other.

[0024] Beneficial effects of the present disclosure:

[0025] The sampling personnel only need to stand on the shore to sample the sampling points far away from the shore. During the sampling process, they can ensure that the water body at the sampling depth is sampled to ensure the accuracy of the water sample. BRIEF DESCRIPTION OF THE DRAWINGS

[0030] The following will be combined with the accompanying drawings in the embodiments of the present disclosure to clearly and completely describe the technical solutions in the embodiments of the present disclosure. Obviously, the embodiments described are only part of the embodiments of the present disclosure, not all of the embodiments. Based on the embodiments of the present disclosure, all other embodiments obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present disclosure.

[0031] In the description of the present disclosure, it should be understood that the terms "opening", "upper", "lower", "thickness", "top", "middle", "length", "inside", "all around" and the like indicating orientation or positional relationship are only for the convenience of describing the present disclosure and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as limiting the present disclosure.

[0032] According to the concept of this application, Figures 1 to 3 The following describes an embodiment of a river and lake water sample collector. Specifically, the river and lake water sample collector is constructed as a split structure, which has a sampling bottle 1, a steel cage 4, a first traction rope 3, a second traction rope 5, a telescopic rod 7 and other components that cooperate with each other. When collecting river and lake water samples, the staff stands on the shore, adjusts the length of the telescopic rod 7 according to the required distance between the sampling point and the shore, and puts the steel cage 4 together with the sampling bottle 1 into the sampling point. By lowering the pitch angle of the telescopic rod 7, the steel cage 4 and the sampling bottle 1 are submerged under water under the weight of the steel cage 4. The sampling depth is controlled by controlling the pitch angle of the telescopic rod 7. At this time, the staff pulls the first traction rope 3 to open the bottle stopper 2, and water flows in from the water inlet 11. When the water fills the sampling bottle 1, the second traction rope 5 is pulled to pull the steel cage 4 together with the sampling bottle 1 out of the water. After the water sample reaches the shore, the steel cage 4 is opened, the sampling bottle 1 is taken out, and the bottle cap is plugged in. The water sample collection is completed.

[0033] like Figure 1-3 As shown, a river and lake water sample collector includes a sampling bottle 1, a water inlet 11 is provided at the upper end of the sampling bottle 1, a bottle stopper 2 is provided in the water inlet 11, a first traction rope 3 is fixedly connected to the bottle stopper 2, the sampling bottle 1 can be detachably installed in a steel cage 4, a second traction rope 5 is fixedly connected to the upper end of the steel cage 4, the first traction rope 3 and the second traction rope 5 pass through the inner circles of two hanging rings 6 together, and the two hanging rings 6 are provided at both ends of a telescopic rod 7.

[0034] When collecting water samples from rivers and lakes, the staff stands on the shore, adjusts the length of the telescopic rod 7 according to the required distance between the sampling point and the shore, and puts the steel cage 4 together with the sampling bottle 1 into the sampling point. By lowering the pitch angle of the telescopic rod 7, the steel cage 4 together with the sampling bottle 1 is submerged in water under the weight of the telescopic rod 7. The sampling depth is controlled by controlling the pitch angle of the telescopic rod 7. At this time, the staff pulls the first traction rope 3 to open the bottle stopper 2, and water flows in from the water inlet 11. When the water fills the sampling bottle 1, the second traction rope 5 is pulled to pull the steel cage 4 together with the sampling bottle 1 out of the water. After the water sample reaches the shore, the steel cage 4 is opened, the sampling bottle 1 is taken out, and the bottle cap is plugged in. The water sample collection is completed.

[0035] Of course, the steel cage 4 in the present application is mainly used to counterweight the sampling bottle 1 so that the sampling bottle 1 can be submerged in water and water can enter the sampling bottle 1 from the water inlet 11. In some embodiments, in order to enable the sampling bottle 1 to be submerged in water, a counterweight is set at the bottom of the sampling bottle 1 to replace the counterweight operation of the steel cage. In this way, the second traction rope 5 can be directly fixedly connected to the upper end of the sampling bottle 1, and the steel cage 4 can be omitted.

[0036] It should be noted that the telescopic rod 7 is a plurality of sleeves of different diameters, which are stacked in sequence to achieve length adjustment of the telescopic tube 7. After the length is adjusted, the fixing function can be achieved.

[0037] Of course, in some embodiments of the telescopic rod 7 in the present application, the telescopic rod 7 can be a hollow structure, so that the first traction rope 3 and the second traction rope 5 can pass through the channel inside the telescopic rod 7 together, replacing the operation of the lifting ring 6, and the lifting ring 6 can be omitted.

[0038] In one embodiment of the present invention, a filter screen is provided around the steel cage 4. The filter screen can block small fish, shrimps and floating objects in the water to prevent the water inlet 11 from being blocked.

[0039] In one embodiment of the present invention, the end of the telescopic rod 7 away from the sampling bottle 1 is rotatably connected to the support 8, wherein a fastening bolt and nut are provided at the connection between the telescopic rod 7 and the support 8. By loosening the bolt and nut, the telescopic rod 7 can rotate about the connection point to adjust the pitch angle, and tightening the bolt and nut can fix the pitch angle of the telescopic rod 7.

[0040] In one embodiment of the present invention, two hand wheels 9 are rotatably connected to the circumference of the support 8, the first traction rope 3 is fixedly connected to one of the hand wheels 9, and the second traction rope 5 is fixedly connected to the other hand wheel 9. By rotating the hand wheels 9, the first traction rope 3 and the second traction rope 5 can be pulled and reeled.

[0041] In one embodiment of the present invention, the lower end of the support 8 is rotatably connected to a disc 10, and the lower end of the disc 10 is fixedly connected to at least three anchor rods 14. The anchor rods 14 are inserted into the ground to increase the stability of the entire device.

[0042] In one embodiment of the present invention, a circular angle disc 12 is fixedly connected to the top of the support 8, and the rotation point between the telescopic rod 7 and the support 8 is on the axis of the circular angle disc 12. By observing whether the scale lines on the telescopic rod 7 and the circular angle disc 12 match, the pitch angle of the telescopic rod 7 can be determined.

[0043] In one embodiment of the present invention, a length scale line is provided on the telescopic rod 7. The length of the telescopic rod 7 can be intuitively understood and the length of the telescopic rod 7 can be adjusted according to the required length.

[0044] In one embodiment of the present invention, floats 13 of different colors distributed at equal distances are fixedly connected to the second traction rope 5 at the upper end of the steel cage 4. By observing the color of the floats 13 on the water surface, the depth of the sampling bottle 1 submerged in the water can be judged.

[0045] The working principle of the present invention is as follows: first, insert the anchor rod 14 into the ground at the shore to stabilize the entire device, adjust the length of the telescopic rod 7 according to the required distance between the sampling point and the shore, rotate the support 8 to drive the telescopic rod 7 to rotate around the support 8, so that the steel cage 4 together with the sampling bottle 1 is located above the water surface of the sampling point, adjust the pitch angle of the telescopic rod 7 so that the steel cage 4 together with the sampling bottle 1 is submerged in the water, and determine the depth of the sampling bottle 1 submerged in the water by observing the float 13, turn one of the hand wheels 9 to pull the first traction rope 3 to open the bottle stopper 2, and water flows in from the water inlet 11. When the water fills the sampling bottle 1, turn the other hand wheel 9 to pull the second traction rope 5 to pull the steel cage 4 together with the sampling bottle 1 out of the water, rotate the support 8, so that the steel cage 4 together with the sampling bottle 1 is transferred to the shore, open the steel cage 4, take out the sampling bottle 1, plug the bottle cap, and the water sample collection is completed.
