[0002] Nowadays, a large amount of water pollution is caused in industry and life, and water resource protection and sewage treatment are crucial. To this end, water plants need to conduct material testing on sewage to plan appropriate multi-channel purification treatment procedures to ensure that the water body can meet the prescribed purification standards.

[0003] In the existing sewage detection procedures, staff usually take sewage samples from a representative area. This method easily ignores the existence of different substances in other areas. If the purification program is set only for the substances detected in this area, it will not be able to purify the substances outside the area, which will affect the purification effect of the entire sewage pool and pose certain risks to the use of water resources.

In this way, the three sampling mechanisms can simultaneously complete automatic sewage sampling for the shallow layer, middle and shallow layer, and deep layer of the water body, and divide the sewage pool into multiple areas for sampling. In this way, corresponding purification plans can be given according to the type and content of substances in each area, thereby ensuring the purification effect of sewage.

DETAILED DESCRIPTION

[0044] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments.

[0046] A floating seat 3, which can carry the sampling device and float on the water surface, and has at least three convex seats 8 arranged in a circumferential array on the top surface thereof, and each convex seat 8 is equipped with a gravity drive mechanism;

[0047] A down pipe 4, the top of which is connected to the middle hole of the floating seat 2, and the bottom of the down pipe 4 is fixedly connected to a drag reducing head 6;

[0048] Sampling mechanisms 5, of which three are provided and are spaced apart and distributed on the side wall of the downpipe 4;

[0049] Specifically, when the positions of the three sampling mechanisms 5 are set, they can satisfy the buoyancy of the floating seat and are located in the shallow layer, the middle shallow layer and the deep layer of the water body respectively;

[0050] A pull rod 15, which is arranged in the sewer pipe 4, and the pull rod 15 can coordinately control the opening and closing states of each sampling mechanism 5;

[0051] The bottom end of the suspension rod 1 is fixedly connected to the pull rod 1, and the top end of the suspension rod 1 is fixedly connected to a top seat 7, and the top seat 7 is synchronously driven by each gravity driving mechanism to move up and down.

[0052] In this embodiment, the drag reducing head 6 adopts a cone structure to reduce the resistance encountered when entering the sewage pool.

[0053] In this embodiment, the sampling mechanism 5 includes

[0054] A water collecting shell 51 is fixed on the side wall of the downpipe 4, and a plug 55 is sealed and plugged at the side opening of the water collecting shell 52;

[0055] Specifically, the plugging head 55 is used for sealing, and after the sewage sampling is completed, the plugging head 55 can be removed to take the sample;

[0056] The second water collecting shell 53 has one end fixedly connected to the first water collecting shell 51, and the other end of the second water collecting shell 53 is fixedly connected to the water inlet pipe head 54;

[0057] And a blocking mechanism, which is arranged in the water collecting shell 2 53 and is close to the water inlet pipe head 54, and the blocking mechanism can block the water inlet pipe head 54.

[0058] In this embodiment, the blocking mechanism includes

[0059] The cylinder shell 60 is fixed in the water collecting shell 2 53 by a support rod;

[0060] A fixing ring 56 fixed in the cylinder shell 60;

[0061] The left end of the pressure seat 58 is matched and slidably arranged in the cylinder shell 60, and the right end of the pressure seat 58 passes through the right port of the cylinder shell 60 and is fixedly connected to the head 59. The head 59 can be matched and pressed with the water inlet pipe head 54. The left end surface of the pressure seat 58 is provided with a sliding groove opening that matches and slides with the fixing ring 56.

[0062] And a second spring 57 is disposed in the sliding groove, and the second spring 57 is connected between the fixing ring 56 and the pressure seat 58.

[0063] In this embodiment, a transmission rod 52 is provided in the water collecting chamber formed by the water collecting shell 1 51 and the water collecting shell 2 53. One end of the transmission rod 52 penetrates into the cylinder shell 60 and is fixedly connected to the pressure seat 58. The other end of the transmission rod 52 passes through the left side opening of the water collecting shell 1 51 and extends out.

[0064] A rotating pin 17 is rotatably mounted in the downpipe 4, and two fixed ends of symmetrical telescopic rods 16 are fixed on the side wall of the rotating pin 17, and the movable ends of the two telescopic rods 16 are rotatably connected to the pull rod 15 and the transmission rod 52 respectively;

[0065] It should be noted that the transmission rod 52 is constrained by the left side opening of the water collecting shell 51 and the orientation of the pressure seat 58, and can only slide left and right;

[0066] That is to say, when the transmission rod 52 is pushed to the right, it cooperates with the tension of the spring 2 57 to push the pressure seat 58. When the pressure seat 58 slides to the limit position in the cylinder shell 60, it can adapt and block the water inlet pipe head 54 through the sealing head.

[0067] When the transmission rod 52 is acted upon by a leftward thrust, it pulls the pressure seat 58 to move leftward and overcomes the elastic force of the spring 2 57 to compress it, thereby causing the seal to move out of the water inlet pipe head, allowing the surrounding water of the water inlet pipe head to flow in freely, thereby automatically completing sewage sampling.

[0068] In this embodiment, a sealing ring is mounted on the side wall of the sealing head 59 .

[0072] Specifically, when the sampling device is hoisted by connecting the top seat 7 with a rope, the suspension rod 1 moves upward based on its own gravity to simultaneously drive the three sampling mechanisms to be in a closed state;

[0073] When the floating seat 3 floats on the water surface, the rope is loosened to greatly reduce the tension of the top seat 7. At this time, the counterweight 10 presses down the handle 9 to flip it downward, thereby pulling down the suspension rod 1, thereby driving the three sampling mechanisms to be in the open state at the same time and taking sewage samples.

[0074] In this embodiment, the upper and lower ends of each inclined rod 2 are rotatably mounted with spring seats 13, and a spring 14 is connected between every two adjacent spring seats 13 to control the two inclined rods to return to the center in time.

[0075] The present invention also provides a sewage detection sampling method, which comprises the following steps:

[0076] Step 1: Divide the sewage pool into 6 areas in advance, namely area A, area B, area C, area D, area E, and area F;

[0077] Step 2: Use a rope to connect to the top seat 7, then suspend the sampling device, and move the suspension rod 1 upward so that each sampling mechanism 5 is in a closed state;

[0078] Step 3: Place the sampling device in the A area of ​​the sewage pool, the floating seat 3 floats on the water surface of the sewage pool, and under the gravity of the counterweight 10, the handle 9 tilts downward to pull the suspension rod 1 to move downward, and then the pull rod 15 drives each sampling mechanism 5 to open synchronously, so that the three sampling mechanisms 5 can sample the sewage in the shallow layer, the middle shallow layer and the deep layer of the A area respectively;

[0079] Step 4: After the sampling is completed, the rope is lifted upward to move the suspension rod 1 upward, so as to drive each sampling mechanism 5 to close synchronously, and move the sampling device to the designated area, and then sample and test the sewage in the shallow layer, middle shallow layer and deep layer of area A;

[0080] Step 5: Repeat steps 2, 3 and 4 to sample and test the sewage in areas B, C, D, E and F in turn.
