Description

Technical Field

[0001] The utility model relates to the technical field of oil exploitation monitoring, in particular to an oil exploitation monitoring device. Background Art

[0002] Oil is one of the main objects of geological exploration, and its main components are mixtures of various alkanes, cycloalkanes, and aromatic hydrocarbons. Oil is mainly used as fuel and gasoline, and is also a raw material for many chemical industrial products, such as solutions, fertilizers, pesticides, and plastics.

[0003] During the oil exploitation process, an oil monitoring device is required. However, most of the existing oil monitoring devices can only be used to monitor the quantity of oil flow, and their functions are relatively single. When it is necessary to sample and detect the oil, it is still necessary to go to the oil outlet end to pick it up. When walking back to the monitoring room after picking it up, the oil will overflow and oxidize to a certain extent when contacting the air, thereby affecting the detection results. At the same time, most of the existing oil monitoring devices cannot be quickly disassembled and installed, and it will be very troublesome when replacement is needed. Summary of the Utility Model

[0019] The technical solution of the present invention will be clearly and completely described below through specific implementation methods.

[0020] like Figures 1-4 As shown, an oil production monitoring device includes a connecting pipe 2, and a second thread groove 22 is vertically opened on the upper end of the circumferential surface of the connecting pipe 2, and the second thread groove 22 opened on the connecting pipe 2 is connected to the interior of the connecting pipe 2; a first thread groove 21 is also vertically opened on the upper end of the circumferential surface of the connecting pipe 2, and the first thread groove 21 is located on the outer circle of the second thread groove 22.

[0021] A lower pressing threaded post 15 is vertically threadedly connected in a threaded groove two 22 formed in a connecting pipe 2. Two circular holes two 14 are vertically formed through the upper end of the lower pressing threaded post 15. Two rectangular grooves one 16 are vertically formed in the upper end of the lower pressing threaded post 15. A monitoring post 23 is vertically inserted, slidably and rotatably installed at the middle position of the lower pressing threaded post 15. On both sides of the circumferential surface of the middle section of the monitoring post 23, clamping plates 24 are fixedly installed. The two clamping plates 24 vertically slide in the two rectangular grooves one 16 formed in the lower pressing threaded post 15 respectively.

[0022] A circular plate 25 is fixedly installed on the circumferential surface of the lower section of the monitoring post 23. Side baffles are vertically arranged upward at the edge of the circular plate 25. A storage groove is formed between the side baffles and the monitoring post 23. The storage groove can be used for storing crude oil. Both the circular plate 25 and the lower section of the monitoring post 23 are located inside the connecting pipe 2.

[0023] An upper pressing post 1 is vertically slidably and rotatably installed on the upper section of the monitoring post 23. Two circular holes one 12 are vertically formed through the upper end of the upper pressing post 1. Rotating plates 11 are fixedly installed on both sides of the circumferential surface of the upper section of the upper pressing post 1. Two rectangular grooves two 17 are vertically formed in the lower end of the upper pressing post 1. The upper pressing post 1 is movably sleeved with the two clamping plates 24 through the two rectangular grooves two 17.

[0024] A rubber ring 13 is vertically slidably installed between the lower pressing threaded post 15 and the upper pressing post 1 in this application. The rubber ring 13 is located in the threaded groove two 22 formed in the connecting pipe 2.

[0025] A top cover 18 is vertically slidably and rotatably installed on the upper section of the monitoring post 23. The inner top wall of the top cover 18 is attached to the upper end surface of the upper pressing post 1. The lower end of the top cover 18 is placed in the threaded groove one 21 formed in the connecting pipe 2 and is threadedly connected.

[0026] When the staff installs this oil extraction monitoring device, first place the monitoring post 23 and the clamping plates 24 into the connecting pipe 2 from the threaded groove two 22 formed in the connecting pipe 2, and at the same time place the lower pressing threaded post 15 into the threaded groove two 22. At this time, the staff then place the two clamping plates 24 on the circumferential surface of the monitoring post 23 into the two rectangular grooves one 16 formed in the upper end of the lower pressing threaded post 15, and then place the rubber ring 13 and place it on the upper end of the lower pressing threaded post 1. After that, the staff place the upper pressing post 1 from the upper end of the monitoring post 23. After placing it, align the rectangular groove two 17 formed in the lower end of the upper pressing post 1 with the two rectangular grooves one 16. At this time, rotate the upper pressing post 1 by means of the rotating plates 11. The upper pressing post 1 drives the lower pressing threaded post 15 to rotate and is threadedly connected and fastened in the threaded groove two 22 through the two clamping plates 24. Finally, the staff place the top cover 18 into the upper end of the monitoring post 23, pass through the monitoring post 23 and threadedly connect it with the threaded groove one 21, and then the installation work of the monitoring device can be completed.

[0027] When the staff needs to sample and detect the internal oil, the top cover 18 can be rotated to separate the top cover 18 from the monitoring column 23, and then the upper pressing column 1 can be lifted up a little to separate the upper pressing column 1 from the two clamping plates 24. Then rotate the upper pressing column 1 so that the circular hole 12 opened at the upper end of the upper pressing column 1 and the circular hole 14 opened on the lower pressing threaded column 15 are located on the same straight line. At this time, the staff can sample and detect the oil passing through the connecting pipe 2 through a straw.

[0028] Through the arranged lower pressing threaded column 15, upper pressing column 1, top cover 18 and monitoring column 23, the oil exploitation monitoring device of the utility model is very convenient for both installation and disassembly, and it is also very convenient for the staff to replace the monitoring column 23. At the same time, by arranging a rubber ring 13 between the lower pressing threaded column 15 and the upper pressing column 1, the sealing performance is good, preventing the oil from volatilizing. Through opening a circular hole 12 on the upper pressing column 1 and a circular hole 14 on the lower pressing threaded column 15, the oil exploitation monitoring device of the utility model can directly sample the oil on it, reducing the contact between the oil and the air, and thus ensuring the accuracy of the detection result.
