Description

Technical Field

[0001] The utility model relates to the technical field of sewage treatment, and specifically relates to a sewage treatment sampling device. Background Technique

[0002] Sewage treatment is a process of purifying sewage to meet the water quality requirements for discharging into a certain water body or reusing it. Sewage sampling and collection are for analyzing and monitoring the components and characteristics in the sewage. By regularly sampling and analyzing sewage samples, the operation effect of sewage treatment facilities can be evaluated, the treatment efficiency, the removal effect of chemical substances during the treatment process, and whether the water quality after treatment meets the discharge standard requirements can be checked.

[0003] The existing sewage sampling usually uses a sampling bottle to collect sewage samples. Its working principle is to insert the sampling bottle into the sewage to collect a certain sample. However, this method can only sample and collect the sewage on the surface or at a certain depth of the sewage. If sampling sewage at different depths, different sampling bottles need to be put in again for collection. Putting corresponding sampling bottles for collecting sewage at different depths will waste a lot of time and manpower and is not easy to operate. Therefore, we have designed a sewage treatment sampling device. Content of the Utility Model

[0004] The utility model purpose of the present utility model is to provide a sewage treatment sampling device, which can collect sewage samples at different depths at any time and place, and can complete multi-section sampling without redundant sampling bottles, saving a lot of time and cost, and solving the problems put forward in the background technique.

[0005] To achieve the above purposes, the present utility model is realized through the following technical solutions: A sewage treatment sampling device includes a base. An installation groove is opened on the upper surface of the base. A servo motor is fixedly installed in the installation groove. A rotating column is placed above the installation groove, and the lower surface of the rotating column is fixedly connected to the output end of the servo motor. A fixed cylinder is movably connected to the outside of the rotating column. The fixed cylinder is fixedly connected to the base through a connecting rod. A sampling mechanism is arranged inside the rotating column;

[0006] The sampling mechanism includes:

[0007] A sliding groove, which is opened on the upper surface of the rotating column;

[0008] A sealing groove, which is opened on the lower surface of the rotating column and is communicated with the sliding groove;

[0009] A collecting cylinder, which is inserted into the sealing groove;

[0010] A top plate, which is fixedly connected to the top end of the collecting cylinder;

[0011] A compression spring, the compression spring is arranged in the sealing groove, and both ends of the compression spring are fixedly connected to the top plate and the inner bottom wall of the sliding groove respectively;

[0012] A collection perforation, the collection perforation is opened on the base and communicated with the sealing groove;

[0013] An electric telescopic rod, the electric telescopic rod is fixedly installed on the inner top wall of the fixed cylinder;

[0014] An inlet hole, the inlet hole is opened on the side surface of the collection cylinder.

[0015] Through the above technical solutions, the whole device of the present application is put into sewage. When it falls to a certain depth, the electric telescopic rod is started to contact the top plate and squeeze the top plate to move it downward, that is, the collection cylinder moves downward through the collection perforation to expose the inlet hole for sewage sampling. After the sampling is completed, the electric telescopic rod shortens and resets, and the top plate and the collection cylinder are reset through the compression spring to complete the sampling. Then, the servo motor is started to drive the rotating column to rotate. After the collection is completed, the collection cylinder rotates and stores, and the next empty collection cylinder rotates to the position of the collection perforation for the next sampling step. As the whole device continues to sink, sampling is carried out again, saving a large amount of sampling time and required cost. A sealed state is maintained between the fixed cylinder and the rotating column, preventing water leakage between the rotating column and the fixed cylinder without affecting the rotation of the rotating column.

[0016] Preferably, the number of the sliding grooves and the sealing grooves is several and they are annularly distributed with the axis of the rotating column as the center. The diameter of the sliding groove is larger than the diameter of the sealing groove.

[0017] Through the above technical solutions, multiple collection cylinders can be arranged in multiple sliding grooves of the present application, so that multi-section sampling can be carried out corresponding to different depths, thereby ensuring the overall practicability of the device.

[0018] Preferably, a sealing gasket is fixedly connected to the inner wall of the sealing groove and is in contact with the outer wall of the collection cylinder. A limiting rod is fixedly connected to the upper surface of the rotating column and is in contact with the top plate.

[0019] Through the above technical solutions, the collection cylinder of the present application remains sealed when not extended, thereby preventing the leakage of sewage and the influx of sewage, which may affect the accuracy of sampling. The arranged limiting rod can limit the top plate to prevent the leakage of the collection cylinder in the sliding groove and the sealing groove.

[0020] Preferably, the electric telescopic rod is fixedly installed at the position corresponding to the collection perforation, and the inner diameter of the collection perforation is the same as the inner diameter of the sealing groove.

[0021] Through the above technical solution, the position design of the electric telescopic rod and the collection perforation in this application enables the electric telescopic rod to extend and push against the collection cylinder at the collection perforation to move downward for sampling, achieving directional sampling and multi-stage sampling.

[0022] Preferably, the length of the sliding groove is greater than the length of the collection perforation, and the water inlet hole is opened at the bottom of the collection cylinder.

[0023] Through the above technical solution, after the collection cylinder in this application moves downward and penetrates the collection perforation, the water inlet hole is exposed, and the sewage can rush into the collection cylinder through the water inlet hole to complete the sampling step.

[0024] Preferably, a buckle is fixedly connected to the top of the fixed cylinder.

[0025] Through the above technical solution, this application connects the whole device to the cable or an external lifting device through the buckle, thereby controlling the sinking of the whole device.

[0026] By adopting the foregoing technical solutions, the beneficial effects of the present utility model are as follows:

[0027] 1. For this sewage treatment sampling device, through the design of the sampling mechanism, sampling can be carried out at any time as the whole device gradually sinks in the sewage, that is, sewage at different depths can be sampled and collected. Multi-stage sampling can be completed without the need to use redundant equipment, and the overall structure is simple, the cost is low, and the operation is convenient, solving the problems raised in the background technology.

[0028] 2. For this sewage treatment sampling device, after sampling the sewage at a certain depth, the collected cylinder after sampling can rotate to store, and at the same time, the next empty collected cylinder changes with the position of the rotating column to sample the sewage at the next depth, achieving sampling and storage simultaneously, saving a large amount of operation time.

[0041] A sealing groove 72 is opened on the lower surface of the rotating column 4 and is communicated with the sliding groove 71;

[0042] A collection cylinder 73 is inserted into the sealing groove 72;

[0048] Through the above technical scheme, the present application puts the device as a whole into the sewage. When it falls to a certain depth, the electric telescopic rod 77 is started to contact the top plate 74 and squeeze the top plate 74 to move it downward, that is, the collecting tube 73 moves downward through the collecting perforation 76 to expose the water inlet 78 for sewage sampling. When the sampling is completed, the electric telescopic rod 77 is shortened and reset, and the top plate 74 and the collecting tube 73 are reset by the compression spring 75 to complete the sampling, and then the servo motor 3 is started to drive the rotating column 4 to rotate. After the collection is completed, the collecting tube 73 is rotated for storage, and the next empty collecting tube 73 is rotated to the position of the collecting perforation 76 for the next sampling step. As the device as a whole continues to sink, sampling is performed again, which saves a lot of sampling time and the required cost. The fixed tube 5 and the rotating column 4 are kept in a sealed state to prevent water leakage between the rotating column 4 and the fixed tube 5 without affecting the rotation of the rotating column 4.

[0049] The number of the sliding grooves 71 and the sealing grooves 72 are both multiple and are distributed in a ring shape with the axis of the rotating column 4 as the center. The diameter of the sliding groove 71 is greater than the diameter of the sealing groove 72 .

The set limit rod 9 can limit the top plate 74 to prevent the collecting tube 73 in the sliding groove 71 and the sealing groove 72 from leaking.

[0053] The electric telescopic rod 77 is fixedly installed at a position corresponding to the collecting through hole 76 , and the inner diameter of the collecting through hole 76 is consistent with the inner diameter of the sealing groove 72 .

[0059] When the sewage treatment sampling device works, the whole device is put into the sewage. When it falls to a certain depth, the electric telescopic rod 77 is started to extend and contact the top plate 74 and squeeze the top plate 74 to move it downward, that is, the collection cylinder 73 moves downward through the collection perforation 76 to expose the water inlet hole 78 for sewage sampling. After the sampling is completed, the electric telescopic rod 77 shortens and resets, and the top plate 74 and the collection cylinder 73 are reset through the compression spring 75 to complete the sampling. Then, the servo motor 3 is started to drive the rotating column 4 to rotate, so that the collection cylinder 73 after collection rotates for storage, and the next empty collection cylinder 73 rotates to the position of the collection perforation 76, and the next sampling step is carried out as the whole device continues to sink.
