[0001] The utility model relates to the technical field of sewage water sample collection, in particular to a large particle matter blocking structure for sewage water sample collection. Background Technique

[0002] With the continuous development and progress of society, there is more and more domestic sewage and industrial wastewater, so environmental monitoring has become particularly important. However, the most common current environmental monitoring is to sample and test the discharged sewage to confirm whether it meets the discharge standards. Now most rivers, lakes and reservoirs are polluted to a certain extent, so it is necessary to regularly detect the water quality therein.

[0003] After retrieval, the prior art with the publication number of CN216816154U discloses a sewage sample collection device, including a bottom rod and a collection cylinder. The top surface of the bottom rod is fixedly clamped with an intermediate rod, and the top surface of the intermediate rod is fixedly clamped with a top rod.

When collecting sewage, the intermediate rod, the top rod and the bottom rod can be connected. The surfaces of the intermediate rod, the top rod and the bottom rod are printed with scales. The staff can hold the top rod and insert the collection cylinder into the sewage, and determine the immersion depth of the collection cylinder by observing the scales on the surfaces of the intermediate rod, the top rod and the bottom rod, so as to conveniently extract sewage at different depths. When extracting, the hand-cranked winch can be rotated, and the hand-cranked winch winds up the pulling rope, driving the pull rod to move upward, thereby driving the piston to move upward and pumping the sewage into the collection cylinder. The device has a simple structure and is easy to use, can collect sewage at different depths, and improves the convenience of sewage sample collection.

[0004] However, when the sample collection device of the utility model extracts sewage, different sizes of particulate impurities or stones will remain in the sewage. If they are all absorbed into the collection cylinder, it is easy to block the water suction pipe, and it is extremely easy to cause difficulties in water inlet and outlet during subsequent water absorption or drainage. Therefore, a large particle matter blocking structure for sewage water sample collection is proposed to solve the problems raised above. Content of the Utility Model

[0009] Furthermore, the sewage absorption assembly includes a piston slidably connected inside the collection cylinder and a connecting rope fixedly connected to the upper side of the piston.

[0010] Furthermore, a transmission roller is rotatably sleeved on the lower side surface of the connecting rope, and a handle is fixedly connected to the upper end of the right side of the column.

[0011] Furthermore, the lower side of the first straight tooth plate is vertically connected to the upper left end of the piston, and the elliptical block is arranged between the movable plate and the fixed plate.

[0012] Furthermore, the outer wall of the lower side of the second straight tooth plate penetrates through the fixed plate and extends to the outside, and a support ring is rotatably sleeved on the middle part of the outer side of the second rotating shaft.

[0013] Furthermore, the support ring is a bearing, and the upper side of the support ring is fixedly connected to the lower left end of the collection cylinder.

[0014] Furthermore, the upper end of the second bevel gear is rotatably sleeved on the lower left end of the collection cylinder.

[0015] Compared with the prior art, the present utility model provides a large particle matter blocking structure for sewage water sample collection, and has the following beneficial effects:

[0016] 1. For the large particle matter blocking structure for sewage water sample collection, the filter screen plate filters the particulate matter in the sewage, and at the same time, the first bevel gear meshes with the second bevel gear to push the cleaning brush to clean the impurities blocked on the lower surface of the filter screen plate.

[0017] 2. The large-particle matter blocking structure for collecting sewage water samples can continuously and effectively clean the impurities blocked under the filter screen plate by rotating the elliptical block to connect the movable plate to the second straight tooth plate upward when the first gear is engaged by the first straight tooth plate, and then cooperating with the second gear, the first bevel gear and the second bevel gear to rotate the cleaning brush. This solves the problem that when the sample collection device pumps sewage, different sizes of particulate impurities or stones in the sewage are likely to be retained. If they are all absorbed into the collection cylinder, it is easy to block the water suction pipe, and it is extremely difficult to draw water in or drain water later.

[0024] Among them, the sewage absorption assembly includes a piston 4 slidably connected inside the collection cylinder 2 and a connecting rope 3 fixedly connected to the upper side of the piston 4. A transmission roller is rotatably sleeved on the lower surface of the connecting rope 3. A handle is fixedly connected to the upper end on the right side of the column 1. The lower side of the first straight tooth plate 7 is vertically connected to the upper left end of the piston 4. The elliptical block 19 is arranged between the movable plate 10 and the fixing plate 12. The outer wall of the lower side of the second straight tooth plate 13 penetrates through the fixing plate 12 and extends to the outside. A support ring is rotatably sleeved on the middle part of the outer side of the second rotating shaft 15. The support ring is a bearing, and the upper side of the support ring is fixedly connected to the lower left end of the collection cylinder 2. The upper end of the second bevel gear 17 is rotatably sleeved on the lower left end of the collection cylinder 2.
