Technical Field

[0001] The utility model relates to the technical field of water sample collecting devices, in particular to a collecting device for surface water detection. Background Art

[0002] Surface water is a general term for four types of water bodies: rivers, glaciers, lakes, and swamps. It is one of the important sources of water for human life. To ensure water safety, surface water quality is generally sampled and tested regularly to prevent water pollution. Therefore, surface water sampling devices are common tools in water quality testing.

[0003] Chinese Patent Authorization Announcement No. CN 215598775 U discloses a surface water treatment collection device, comprising a housing, wherein a first water storage tank and a second water storage tank are provided inside the housing, wherein the first water storage tank is located above the second water storage tank, and a first water outlet and a second water outlet are provided on the left side wall of the housing, wherein the first water outlet is connected to the first water storage tank. When the water pump reaches the bottom of the water area, the water resources in the deep water area can be extracted into the second water storage tank. The setting of this structure provides data comparison for subsequent detection work and improves the accuracy of the detection results. The above-mentioned prior art solution has the following shortcomings: the collection device mainly relies on the suction of the water pump to realize the extraction of deep water flow. However, in actual collection work, the use of the water pump makes the device inconvenient to carry and is not conducive to the horizontal multi-point water sampling work of large-scale water flow in ponds, so there is room for improvement.

A sampler is stuck in the interior of the limiting mechanism, and one end of the sampler passes through the interior of the pull ring.

[0006] Preferably, three pull rings are provided, and the pull rings are distributed at equal intervals on the connecting rope.

[0007] Preferably, the number of the limiting mechanisms is the same as the number of the pull rings, and the limiting mechanisms are located on the left side of the pull rings. When the second magnetic block moves to the left, the pull ring gradually moves away from the limiting mechanisms.

[0008] Preferably, the limiting mechanism includes a snap ring installed between the two positioning plates, and a friction pad is installed on the inner side wall of the snap ring, and a stopper is evenly installed on one end of the snap ring close to the pull ring.

A second magnetic block 1106 is embedded on the side near the handle 6, a fixed rod 1102 is installed on the side of the top of the handle 6 near the second guide roller 4, the connecting rope 5 passes through the interior of the fixed plate 1101, and an L-shaped movable plate 1103 is fixedly sleeved on the side of the connecting rope 5 near the fixed plate 1101. A first magnetic block 1105 is embedded on one side of the L-shaped movable plate 1103, and the first magnetic block 1105 and the second magnetic block 1106 attract each other. An annular rope 1104 is installed on the top of the L-shaped movable plate 1103, and a pull ring 7 is evenly installed on the side of the connecting rope 5 below the collection rod 1;

[0023] There are three pull rings 7, and the pull rings 7 are evenly spaced on the connecting rope 5;

[0024] Specifically, such as Figure 1 、 Figure 2 and Figure 3 As shown, when in use, the second magnetic block 1106 and the fixed plate 1101 are used to fix the right side of the L-shaped movable plate 1103, and the circular rope 1104 and the fixed rod 1102 are used to fix the left side of the L-shaped movable plate 1103, thereby limiting the moving distance of the connecting rope 5 to ensure the stability of subsequent water sample collection;

[0025] A locking ring 8 is sleeved on the top of the pull ring 7, and multiple sets of relatively arranged positioning plates 12 are evenly installed on both sides of the collection rod 1, and a limiting mechanism 9 is connected between two relatively arranged positioning plates 12;

[0026] The number of the limiting mechanisms 9 is the same as the number of the pull rings 7, and the limiting mechanism 9 is located on the left side of the pull ring 7. When the second magnetic block 1106 moves to the left, the pull ring 7 gradually moves away from the limiting mechanism 9.

[0027] The limiting mechanism 9 includes a snap ring 901 installed between the two positioning plates 12, and a friction pad 902 is installed on the inner side wall of the snap ring 901. A stopper 903 is evenly installed on the end of the snap ring 901 close to the pull ring 7;

[0028] The snap ring 901 is a C-shaped structure, and the stoppers 903 are distributed in a ring shape with equal intervals on the snap ring 901;

[0029] Specifically, such as Figure 1 、 Figure 4 As shown, when in use, the clamping ring 901 and the friction pad 902 cooperate to quickly clamp and fix the water collecting cylinder 1001, and the friction pad 902 is used to increase the friction between the water collecting cylinder 1001 and the friction pad 902, making the clamping more stable;

[0030] A sampler 10 is inserted into the interior of the limiting mechanism 9, and one end of the sampler 10 passes through the interior of the pull ring 7;

[0031] The sampler 10 includes a water collecting cylinder 1001, and a piston rod 1002 is passed through one end of the water collecting cylinder 1001, and a pull block 1003 is installed on the end of the piston rod 1002 away from the water collecting cylinder 1001, and a water extraction pipe 1004 is installed on the side of the water collecting cylinder 1001 away from the pull block 1003;

[0032] The water collecting cylinder 1001 is inserted into the inner part of the clamping ring 901, and the end of the water collecting cylinder 1001 close to the pull block 1003 abuts against the inner side wall of the stop block 903, and the end of the piston rod 1002 close to the pull block 1003 passes through the inner part of the pull ring 7;

[0033] Specifically, such as Figure 1 、 Figure 4 As shown, when in use, the piston rod 1002 is used to extend and retract inside the water collecting cylinder 1001 to adjust the air pressure of the water collecting cylinder 1001, so that the water collecting cylinder 1001 forms a negative pressure, and the water pumping pipe 1004 generates suction on the water flow.

[0034] Working principle: When using the utility model, first, according to the specific location where the water sample needs to be collected, the water collection cylinder 1001 is clamped into the corresponding clamping ring 901, so that the outer wall of the water collection cylinder 1001 is against the friction pad 902, and one end of the water collection cylinder 1001 is against the inner wall of the stopper 903, and then the corresponding pull ring 7 is put on the outside of the piston rod 1002, and the locking ring 8 is pulled downward to prevent the pull ring 7 from separating from the piston rod 1002;

[0035] Secondly, the handle 6 is used to place the entire collection rod 1 above the water body, so that the water extraction pipe 1004 is placed in the water, and then the L-shaped movable plate 1103 is pulled to the left, so that the pulling block 1003 pulls the upper connecting rope 5 to move synchronously until the water extraction pipe 1004 can be sleeved on the fixing rod 1102, thereby fixing the connecting rope 5. During the pulling process of the upper connecting rope 5, the lower connecting rope 5 drives the pull ring 7 to move to the right, so that the pull ring 7 pulls the pull block 1003, so that the piston rod 1002 moves to the right, thereby forming a negative pressure inside the water collecting cylinder 1001, causing the water extraction pipe 1004 to generate suction on the water flow, and then the water flow enters the interior of the water collecting cylinder 1001 to complete the sampling work;

[0036] Finally, retract the collection rod 1, detach the pull ring 7 from the piston rod 1002, and then separate the water collecting cylinder 1001 from the snap ring 901 to facilitate the processing of the water sample. By changing the water collecting cylinder 1001 and engaging it with different snap rings 901, water samples at different distances can be collected.
