Description

Technical Field

[0001] The utility model relates to the technical field of sewage sampling, in particular to a sewage sampling device for oil production. Background Art

[0002] Oil extraction refers to the act of digging and extracting oil from places where oil is stored. Oil extraction wastewater mainly comes from different sections such as drilling, oil production, well washing, and underground operations. The wastewater discharged from these sections contains pollutants such as petroleum, volatile phenols, and sulfides. It is necessary to use a wastewater sampling device to sample and analyze the wastewater;

[0003] In the prior art, the Chinese utility model with publication number: CN213481813U discloses an environmentally friendly oil production wastewater sampling device, which solves the problem that the existing oil production wastewater sampling device has a simple structure, and different sampling bottles are needed to sample wastewater at different positions. A single sampling bottle cannot achieve simultaneous sampling of the upper, middle and lower three positions, which not only brings inconvenience to the work of the sampling personnel, but also leads to the problem that the wastewater analysis results are not accurate enough. The key point of its technical solution is right one, and the effect is that by setting three water inlets, the device has three sewage inlets, and by turning the handle to drive the rotating rod to rotate, the circular block and the water inlet are staggered to open the three sewage inlets, ensuring that the device can sample sewage at the upper, middle and lower three positions at the same time, reducing the work procedures of the sampling personnel and improving the accuracy of the sewage detection results;

[0004] Although the above technical solution can sample sewage at three locations, upper, middle and lower, when the depth of the sewage is different, the sampling device needs to select a sampling device of corresponding length according to the depth of the sewage. However, this requires storing more sampling devices in the warehouse, thereby occupying the storage space of the warehouse. At the same time, the sampling position is fixed, and it is not possible to select sewage of corresponding depth for sampling according to actual conditions. Therefore, we need to propose an oil extraction sewage sampling device. Utility Model Content

[0026] See also Figure 1-4 The utility model provides a technical solution: a petroleum mining wastewater sampling device, comprising:

[0027] A holding mechanism 100, a control box 200 is disposed at the upper end of the holding mechanism 100, a displacement mechanism 300 is disposed inside the holding mechanism 100, a connecting mechanism 400 is mounted on the displacement mechanism 300, and a plurality of sampling mechanisms 500 are detachably mounted on the connecting mechanism 400;

[0028] The holding mechanism 100 includes a protective housing 101;

[0029] The displacement mechanism 300 includes a forward and reverse motor 301, a driving synchronous roller 302, a driven synchronous roller 304 and a synchronous belt 303. The two ends of the synchronous belt 303 are respectively connected to the driving synchronous roller 302 and the driven synchronous roller 304. One end of the driving synchronous roller 302 penetrates the protective housing 101 and is driven by the forward and reverse motor 301.

[0030] The connecting mechanism 400 includes a connecting seat 401, a slot 402 for the synchronous belt 303 to be embedded in one side of the connecting seat 401, a locking bolt 403 passing through the synchronous belt 303 is inserted into the side of the connecting seat 401 adjacent to the slot 402, a guide block 404 is fixedly connected to the side opposite to the connecting seat 401 and the locking bolt 403, and a guide groove 103 for the guide block 404 to be slidably connected is opened on one side of the protective shell 101.

[0031] The sampling mechanism 500 includes a sampling barrel 501, the inner cavity of the sampling barrel 501 is fixedly connected with a partition 504, the upper surface of the partition 504 is installed with an electric push rod 506, the telescopic end of the electric push rod 506 is fixedly connected with a push block 507, the push block 507 is slidably connected with a grooved ladder block 512, one side of the grooved ladder block 512 is fixedly connected with a sealing plate 510, one side of the sealing plate 510 is fixedly connected with a sealing gasket 511, and one side of the sampling barrel 501 is provided with a sampling hole 503 for the sealing gasket 511 to be embedded. Through the arrangement of the grooved ladder block 512 and the push block 507, the groove of the grooved ladder block 512 is arranged in an inclined triangular groove, and the push block 507 is a right-angled triangular block, so that the push block 507 descends and at the same time contacts the grooved ladder block 512 away from the sampling hole 503, so that the sealing gasket 511 on the sealing plate 510 is separated from the sampling hole 503, thereby facilitating the sampling of sewage.

[0032] The inner cavity of the sampling tube 501 is fixedly connected with multiple groups of guide rods 508 for sliding and inserting the sealing plate 510. The multiple groups of guide rods 508 are arranged in a rectangular array. The outer sides of the multiple groups of guide rods 508 are sleeved with springs 509. The moving direction of the sealing plate 510 is guided by the multiple groups of guide rods 508. After the sewage sampling is completed, the control box 200 controls the electric push rod 506 to reset, and then the sealing plate 510 is reset under the action of the spring 509, so that the sealing gasket 511 is embedded in the sampling hole 503, which is convenient for taking out the sampled sewage.

[0033] A battery 505 electrically connected to the electric push rod 506 is installed in the cavity above the partition 504 and between the sampling tube 501. A drain valve pipe is provided at the lower end of one side of the sampling tube 501. The drain valve pipe is used to discharge the sampled sewage for collection.

[0036] A limiting plate 102 which is slidably connected to the connecting seat 401 is fixedly connected to one side of the inner cavity of the protective shell 101. The lower surface of the protective shell 101 is open. A handle 104 is fixedly connected to the upper end of the other side of the protective shell 101. The handle 104 is convenient for staff to take the sample. At the same time, the opening makes it convenient for the sampling device to sink into the water, thereby reducing the impact on welfare.

[0037] Both ends of the driving synchronous roller 302 and the driven synchronous roller 304 are fixedly connected with limit rings 305 for limiting the synchronous belt 303. The upper surface of the grooved ladder block 512 is provided with a triangular groove for the sliding connection of the push block 507. The position of the synchronous belt 303 is limited by the limit ring 305 to prevent the position deviation of the synchronous belt 303 from affecting the lifting and lowering of the displacement mechanism 300.

[0038] When in use, the staff holds the handle 104 to vertically insert the protective shell 101 into the water, and controls the forward and reverse motor 301 to rotate forward through the control box 200 to drive the synchronous roller 302 to rotate, so that the synchronous belt 303 drives the connecting seat 401 to descend along the limit plate 102, so as to move the sampling mechanism 500 to the sewage depth to be sampled, and controls the control box 200 to start a group of electric push rods 506 of the sampling mechanism 500 to extend and contact the grooved ladder block 512, so that the sealing The plate 510 is away from the sampling hole 503, and the sewage is used to flow into the sampling tube 501. After the sampling is completed, the control box 200 controls the electric push rod 506 to reset, and under the action of the spring 509, the sealing plate 510 drives the sealing gasket 511 to block the sampling hole 503, and the sampling of the sewage is completed. Repeat the above operation to adjust the depth of other sampling mechanisms 500, and then sample sewage at different depths, improve the sampling efficiency, and realize multi-layer sampling. After the sampling is completed, the collected sewage is collected and tested through the discharge valve pipe, which improves practicality.
