Description

[Technical field]

[0001] The utility model relates to the technical field of sewage sampling equipment, in particular to a sampling device for sewage detection. [Background technology]

[0002] Sewage refers to the discharged water from life and production that is polluted to a certain extent. Water that has lost its original use function is referred to as sewage. It is mainly water used in life. It contains more organic matter and is easier to handle. In order to detect sewage, sewage detection equipment will be used. By using sewage detection equipment to detect sewage, the content in sewage can be effectively detected. For sewage detection, it is generally necessary to sample the sewage and put the sampled sewage into the detection equipment for detection. Common sewage sampling equipment is as follows:

After the sewage is injected into the processing frame and causes a corresponding impact force on the transmission blades, the utility model can drive the transmission blades to rotate synchronously with the fixed rod, so that the transmission gear can rotate accordingly, and then combined with the meshing of the transmission rack and the transmission gear, the cleaning scraper can push and clean the impurities accumulated on the surface of the filter plate while conveying the sewage, reducing the labor consumption required for the operator to manually clean the impurities on the filter plate, while avoiding the accumulation of impurities affecting the quality of sewage sampling and impurity removal. It is more practical and suitable for wide promotion and use.

[0026] like Figures 1 to 4 , a sampling device for sewage detection, comprising: a connecting rod 1, a filter screen 2, and a support block 3 driven to slide and connect to the connecting rod 1, wherein the support block 3 is driven by a lead screw 26 and a motor 27, the motor 27 is fixedly connected to the connecting rod 1, and its output shaft is threadedly connected to the lead screw 26 rotatably connected to the connecting rod 1, so that the lead screw 26 is driven to rotate by the motor 27, and the lead screw 26 drives the support block 3 threadedly connected to it to move, thereby realizing the lifting and lowering of the support block 3, and then adjusting the position of the collection bucket 4;

[0027] The sampling device in the utility model further comprises: a collection barrel 4 with a built-in chamber 5, a partition plate 6, a sealing plate 1 8, a sealing plate 2 9 and a driving mechanism;

[0028] The collecting barrel 4 is detachably fixedly connected to the supporting block 3 and can move with the supporting block 3, and the partition plate 6 is fixedly connected in the collecting barrel 4 and is mainly used to separate the chamber 5. When sewage needs to be sampled, the sewage is stored through the liquid inlet hole 7 provided on the side wall of the collecting barrel 4, and the filter net 2 fixedly connected to the liquid inlet hole 7 filters plastic bags and other substances to prevent plastic bags and other substances from entering the chamber 5;

[0029] When the filter screen 2 is clogged, the driving mechanism drives the sealing plate 1 8 and the sealing plate 2 9 connected to the partition plate 6 to rotate, so that the sealing plate 1 8 is opened and the sealing plate 2 9 is closed. When the sealing plate 2 9 closes the liquid inlet hole 7, the sewage enters the chamber 5 near the sealing plate 1 8 to achieve sewage storage.

[0030] Specifically, since the driving mechanism includes a support rod 10, a fixing rod 11 and a fixing rod 2 12, the support rod 10 is rotatably connected to the partition plate 6, and both ends extend to the chambers 5 on both sides of the partition plate 6, respectively, the fixing rod 11 is fixedly connected to one end of the support rod 10 close to the sealing plate 1 8, and the end of the fixing rod 11 away from the support rod 10 is fixedly connected to the sealing plate 1 8, and the fixing rod 2 12 is fixedly connected to the side wall of the support rod 10 close to the sealing plate 2 9, and the end of the fixing rod 2 12 away from the support rod 10 is fixedly connected to the sealing plate 1 8. Plate 2 9 is fixedly connected, so the support rod 10 connected to the partition plate 6 is driven to rotate, and the support rod 10 drives the fixed rod 11 and the fixed rod 2 12 to rotate, so that the fixed rod 11 and the fixed rod 2 12 drive the sealing plate 1 8 and the sealing plate 2 9 to rotate, thereby achieving the switching of the liquid inlet 7 to open. It is worth mentioning that the driving mode of the support rod 10 is driven by the motor 28, and the motor 28 is fixedly connected to the collection barrel 4, and one end is fixedly connected to the support rod 10, so that the rotation of the support rod 10 can be realized.

[0031] Specifically, when the liquid inlet 7 is blocked, since the sealing plate 1 8 and the sealing plate 2 9 are both provided with an air storage chamber 13 for transmitting airflow, an air pump 14 is fixedly connected to the connecting rod 1, and the air pump 14 is communicated with the air storage chamber 13 through a transmission pipe 15. The sealing plate 1 8 and the sealing plate 2 9 are both fixedly connected with a high-pressure air nozzle 16 communicated with the air storage chamber 13, and a one-way valve 17 is fixedly connected to the transmission pipe 15. Therefore, the air pump 14 is started, and the air pump 14 transmits the airflow into the storage chamber, and the airflow enters the high-pressure nozzle through the storage chamber, so that the high-pressure nozzle blows air to the filter net 2, so that materials such as plastic bags are away from the filter net 2, thereby reducing the blockage of the filter net 2.

[0032] Specifically, when the liquid inlet 7 needs to be sealed, the support rod 10 rotates, and the rotating rod 20 drives the rotating rod 20 fixedly connected to the insertion rod to rotate, so that the rotating rod 20 drives the sealing plate three 18 and the sealing plate four 19 that are rotatably connected in the collecting barrel 4 and fixedly connected thereto to rotate, thereby realizing the sealing plate three 18 and the sealing plate four 19 to seal the liquid inlet 7.

[0033] Specifically, when the collecting barrel 4 needs to be disassembled, since the supporting block 3 is swingably connected with the fixing rings 21 which are relatively arranged, and one of the fixing rings 21 is rotatably connected with a bolt 22, and one end of the bolt 22 is threadedly connected to the other fixing ring 21, a person turns the bolt 22 to detach the other fixing ring 21 through the bolt 22, and thus the collecting barrel 4 can be removed by swinging the fixing ring 21.

[0034] Specifically, the collecting barrel 4 is swingably connected to the side walls at both ends of the partition plate 6 with a connecting plate 23, and a sealing gasket 24 is fixedly connected to the connecting plate 23. The sealing gasket 24 can be attached to the side walls of the collecting barrel 4. One end of the connecting plate 23 is snap-connected to the collecting barrel 4. When the inside of the collecting barrel 4 needs to be cleaned, the staff opens the snap and cleans the chamber 5 by opening the connecting plate 23. The sealing gasket 24 is used to increase the sealing effect of the collecting barrel 4.

[0035] Specifically, a conical column 25 is fixedly connected to the bottom surface of the connecting rod 1, so that personnel can insert the connecting rod 1 to the bottom of the sewage easily.

[0036] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
