DETAILED DESCRIPTION

[0020] With reference to the drawings of the embodiments of the present application, the technical solutions in the embodiments of the present application will be clearly and completely described, obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments of the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of the present application.

[0021] Please refer to Figs. 1-3 The utility model provides an automatic metering monitoring device of oil well, including casing 1, the outer surface fixed connection of casing 1 has inlet pipe 2 and outlet pipe 3, and the inside rotation is connected two gear 4 of casing 1, the upper surface of casing 1 is provided with end cover 5, and the top of end cover 5 is provided with quick -release structure 6, and the top fixed connection of end cover 5 has wiring tube 7, and the top of wiring tube 7 is connected with sensor 8;

[0022] Quick -release structure 6 includes side block 61, the outer surface rotation is connected with connecting plate 62 of side block 61, and one end of connecting plate 62 is fixedly connected with the lever 63, and the lower surface of connecting plate 62 is fixedly connected with pin rod one 64 near one end position, and the inside of pin rod one 64 is inserted with compression spring 65, and the other end of connecting plate 62 is fixedly connected with inclined rod 66, and the bottom of inclined rod 66 is hinged with locking hook 67.

[0023] Specifically, the inside of casing 1 is rotationally provided with two intermeshing gear 4, and the shaft of one of the gear 4 is connected with sensor 8.

[0024] The advantages are that the flanges of the inlet pipe 2 and the outlet pipe 3 are connected with the oil well pipeline, so that the oil and gas enters the inside of the casing 1 through the inlet pipe 2, and the rotation of the gear 4 is driven after entering the inside of the casing 1. The rotation of the gear 4 is based on the power generated by the flow of oil and gas, and the rotation state can reflect the flow information of oil and gas. Because the size of the oil and gas flow directly affects the speed of the gear 4 rotation, the larger the flow, the faster the gear 4 rotates; the smaller the flow, the slower the gear 4 rotates. Since the sensor 8 is connected to the shaft of one of the gear 4, its main function is to convert the rotation information of the gear 4 into an electrical signal. The built-in chip analyzes these signals to accurately obtain the flow data of oil and gas, thereby effectively monitoring the production status of the oil well.

[0025] Specifically, the end of the inlet pipe 2 and the outlet pipe 3 away from the casing 1 is fixedly connected with a flange, and the inside of the inlet pipe 2 is embedded with a filter screen 9.

[0026] The advantage is that the filter screen 9 is embedded in the inlet pipe 2, which mainly filters the oil gas entering the device. Due to the complex oil well environment, the oil gas often contains a large amount of oil stains, impurities and scale, etc. If these impurities directly enter the internal device, it may cause the key components such as gear 4 to wear out and affect the normal rotation, thereby reducing the accuracy of measurement and monitoring. The filter screen 9 can effectively intercept these impurities and protect the mechanical structure inside the device to ensure the stable operation of the gear 4 and other components.

[0027] Specifically, the top surface of the shell 1 is provided with a ring groove 10, and the ring groove 10 is embedded with a sealing ring 11.

[0028] Specifically, the top of the end cover 5 is provided with several groups of quick release structures 6 around the axial direction thereof, and the bottom end of the side block 61 is fixedly connected to the upper surface of the end cover 5.

[0029] Specifically, the upper surface of the end cover 5 is fixedly connected with several pin rods two 12 around the axial direction thereof, one end of the compression spring 65 is inserted into the inside of the pin rod one 64, and the other end of the compression spring 65 is inserted into the inside of the pin rod two 12.

[0030] The advantage is that in the normal state, the locking hooks 67 in the several groups of quick release structures 6 hook the edges of the shell 1, so that the end cover 5 is pressed on the top of the shell 1, and the end cover 5 tightly presses the sealing ring 11 to ensure the sealing performance; when it is necessary to disassemble the shell 1 and the end cover 5, the lever 63 is pressed downward to drive the connecting plate 62 to rotate around the shaft connected with the side block 61, so that the connecting plate 62 drives the inclined rod 66 to shift downward, and the inclined rod 66 drives the locking hook 67 to move downward, so that the locking hook 67 is separated from the edge of the top of the shell 1, and the locking hook 67 is manually actuated to make the front end of the locking hook 67 contact the edge of the end cover 5. Even after the lever 63 is released, the locking hook 67 will not be hooked on the edge of the top of the shell 1 again; the remaining several groups of quick release structures 6 are disassembled in this way, and the overall structure is convenient for quickly disassembling and separating the shell 1 and the end cover 5, so that the efficiency can be improved when maintaining the inside of the shell 1.

[0031] In use, first, the inlet pipe 2 and the outlet pipe 3 are connected with the oil well pipeline away from the flange plate at one end of the shell 1; the oil gas enters the device through the inlet pipe 2, the filter screen 9 inside the inlet pipe 2 filters the oil gas to prevent impurities from entering the inside of the device; the oil gas entering the inside of the shell 1 drives the two intermeshing gears 4 to rotate, the shaft of one of the gears 4 is connected with the sensor 8, the sensor 8 converts the rotation information of the gear 4 into an electric signal, the built-in chip analyzes the signal to obtain the oil gas flow data, and the production condition of the oil well is monitored; when the inside of the shell 1 needs to be maintained, the push rod 63 is pressed downward, the connecting plate 62 is driven to rotate around the shaft connected with the side block 61, the connecting plate 62 drives the inclined rod 66 to deviate downward, the inclined rod 66 drives the locking hook 67 to be separated downward from the edge at the top of the shell 1, and then the locking hook 67 is manually pushed to make the front end of the locking hook 67 contact the edge of the end cover 5, so that the remaining several groups of quick release structures 6 are disassembled, and the shell 1 and the end cover 5 are quickly disassembled and separated.

[0032] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present application, and the scope of the present application is defined by the appended claims and their equivalents.
