Description

Technical Field

[0001] The invention relates to the technical field of wired transmission, and in particular to an intelligent anti-electromagnetic interference device for deep well power line carrier communication. Background Art

[0002] During oil extraction, underground mining equipment is usually located several thousand meters above the ground, with high temperatures and harsh environments. Optical fiber transmission or power line carrier transmission is generally used to achieve ground control of underground systems. For environments where laying optical cables is difficult, power line carrier transmission, which does not require additional transmission lines, is usually selected as a communication method. Carriers are generally electromagnetic waves that can load ordinary signals onto high-frequency signals of a certain frequency. According to the signal frequency, carrier signals can be divided into narrowband carrier communication and broadband carrier communication. For underground space limitations and high-temperature environments, narrowband power line carrier transmission is often used because broadband carrier communication has high transmission power and generates high heat.

The carrier module is provided with a heat dissipation device, so that the carrier module can quickly release heat to the environment and improve its service life.

[0004] There are still some deficiencies in the use of the anti-electromagnetic interference device in the prior art: When the anti-electromagnetic interference equipment is installed in a deep well for a long time, the environment in the deep well is relatively humid, so during the long-term use of the anti-electromagnetic interference equipment, it is easy to be damaged by moisture interference; When the current anti-electromagnetic interference equipment is ventilated and heatsinked, the air in the well is in a humid state, so the anti-electromagnetic interference equipment is easily damaged by moisture and cannot work stably.

[0025] The anti-electromagnetic interference device 6 is selected as the technical solution of announcement number CN113794491B. When working, the ground controller outputs a signal to the ground carrier module to convert it into a carrier signal, and then transmits it to the downhole carrier module through the transmitting end LA through the power line over a long distance, and then the downhole carrier module transmits the signal to the remote control module to realize the ground controller to control the state of the downhole actuator and read the signal of the downhole detection element. The remote control module includes an analog receiving port, a switch receiving port, a switch output port and an analog output port, which can establish communication with the ground controller through carrier transmission, receive commands issued by the uphole controller, and feedback signals to the ground controller.

[0026] Reference Figure 2 The positioning mechanism includes a limiting rod 7 fixedly installed on the four corners of the inner wall of the top of the U-shaped cover plate 3, and a limiting tube 8 is slidably sleeved on the limiting rod 7. The bottom ends of the four limiting tubes 8 are fixedly installed with the same pressing plate 9. The pressing plate 9 cooperates with the transmission mechanism. Two arc-shaped card plates 10 are symmetrically fixedly installed at the bottom of the pressing plate 9. The two arc-shaped card plates 10 are both clamped with the anti-electromagnetic interference device 6. After the pressing plate 9 receives the power of the transmission mechanism, it can move downward, thereby driving the two arc-shaped card plates 10 to move downward. Therefore, when the anti-electromagnetic interference device 6 is moved into the protective box 1, the anti-electromagnetic interference device 6 can be automatically positioned and pressed. Figure 2 In the figure, a limiting spring 15 is sleeved on the limiting rod 7 and is located above the limiting tube 8. The top and bottom ends of the limiting spring 15 are fixedly connected to the top inner wall of the U-shaped cover 3 and the top of the limiting tube 8 respectively.

When the U-shaped cover 3 is pushed into the protection box 1, the cam 17 can be driven to rotate through the mounting shaft after the moving rack 19 and the driving gear 18 are meshed and transmitted. In the process of rotating the cam 17 to a vertical position, the pressure plate 9 can be pushed downward while the bottom of the cam 17 keeps in contact with the pressure plate 9, so as to facilitate the positioning and clamping of the anti-electromagnetic interference equipment 6. Fig.11In the embodiment, a mounting plate 20 is fixedly installed at the bottom of the mounting rod 16, and a ball head rod 21 is slidably connected to the mounting plate 20. One end of the ball head rod 21 is in contact with one side of the cam 17, and a support spring 22 is sleeved on the ball head rod 21 and is located on one side of the mounting plate 20. The two ends of the support spring 22 are respectively fixedly connected to one side of the mounting plate 20 and the other end of the ball head rod 21. When the cam 17 rotates in the vertical direction, it can maintain contact with the ball head rod 21. Later, during the rotation of the cam 17, the ball head rod 21 can be pushed to move along the mounting plate 20, so that the support spring 22 is in a stressed state. The support spring 22 in the stressed state can provide a reverse thrust to the cam 17 through the ball head rod 21, so that the cam 17 can be elastically limited.

[0028] Reference Figure 4 The clamping mechanism includes a clamping rod 11 that penetrates the U-shaped cover 3 and is slidably connected to the U-shaped cover 3. A positioning cover 13 is fixedly installed on the top inner wall of the protective box 1.

The top and bottom ends of the tension spring 12 are fixedly connected to the top inner wall of the U-shaped cover 3 and the bottom end of the clamping rod 11 respectively. After the U-shaped cover 3 is completely transferred into the protective box 1, the clamping rod 11 can be moved to the positioning cover. 13 corresponds to the position, and the tension spring 12 which is in a stressed state can use its elastic force to drive the clamping rod 11 to move upward, so that the clamping rod 11 is inserted into the corresponding positioning cover 13. Therefore, when the clamping rod 11 and the positioning cover 13 are clamped and positioned, the U-shaped cover 3 can be positioned, so that the protection box 1 can be stably blocked, thereby realizing protection against electromagnetic interference equipment 6, and by pushing the push rod 14 downward and moving the clamping rod 11 into the protection box 1, the positioning clamping of the U-shaped cover 3 can be released, and the U-shaped cover 3 can be removed from the protection box 1, so that the anti-electromagnetic interference equipment 6 can be conveniently removed from the protection box 1.

As the air pressure in the protection box 1 increases Afterwards, the sealing ball 41 can move under the action of gas pressure to release the blockage of the exhaust pipe 39, so that the gas in the protective box 1 can be discharged, and the reset spring 38 is arranged to elastically pull the sealing ball 41, so as to ensure that a constant gas pressure is maintained in the protective box 1 and avoid excessively fast gas flow speed, so that when the gas is used to cool down the anti-electromagnetic interference device 6 for heat dissipation, the gas can maintain sufficient contact with the anti-electromagnetic interference device 6, so as to achieve more balanced heat dissipation of the anti-electromagnetic interference device 6.

[0034] In the present invention, the protection box 1 is first installed at a specified position in the deep well through four lifting ears 2, and then the anti-electromagnetic interference device 6 can be set on the positioning ring 5, and then the U-shaped cover 3 can be pushed to push the anti-electromagnetic interference device 6 into the protection box 1. After the moving rack 19 moves and engages with the driving gear 18, the cam 17 can be driven to rotate through the installation shaft. In the process of rotating the cam 17 to a vertical position, the pressure plate 9 can be pushed downward while the bottom of the cam 17 keeps in contact with the pressure plate 9, thereby driving the two arc-shaped clamping plates 10 to move downward. After the U-shaped cover 3 is completely moved into the protection box 1, the two arc-shaped clamping plates 10 can be used to position and clamp the anti-electromagnetic interference device 6, and in the U-shaped When the cover plate 3 moves, the two clamping rods 11 can be driven to move. After the two arc-shaped clamping plates 10 are used to position and clamp the electromagnetic interference device 6, the clamping rod 11 moves to a position corresponding to the positioning cover 13. At this time, the tension spring 12 in a stressed state can use its elastic force to drive the clamping rod 11 to move upward, so that the clamping rod 11 is inserted into the corresponding positioning cover 13. Therefore, when the clamping rod 11 and the positioning cover 13 are clamped and positioned, the U-shaped cover plate 3 can be positioned, so that the protective box 1 can be stably blocked, thereby protecting the electromagnetic interference device 6. When the U-shaped cover plate 3 moves, the conveying pipe 26 and the clamping ring 31 can be kept docked, so that when the electromagnetic interference device 6 is ventilated and heat is dissipated, When the driving motor 24 is started to drive the driving shaft 34 to rotate, the blades 35 can be driven to rotate, thereby forming suction, and the external gas can be transported to the connecting box 25 through the two air inlet holes, and then the gas can be transported to the insert pipe 28 without passing through the delivery pipe 26. Then the gas can be transported to the diversion box 27 by the insert pipe 28, and can be dispersed and transported to the corresponding dispersion box 30 through the two connecting pipes 29, and then the gas can be dispersed and transported to the protective box 1 through multiple dispersion holes, so that ventilation and heat dissipation can be performed when the anti-electromagnetic interference device 6 is working, and when the gas passes through the sponge mesh cover 33, the moisture and dust in the gas can be filtered after being filtered by the sponge mesh cover 33, and the sponge mesh cover 33 Keep rotating, so it can fully receive the squeezing of the two pressure rods 36, so it can squeeze out the moisture absorbed in the sponge mesh cover 33 and drop it into the connecting box 25, and then it can be discharged through the drain pipe 37, so that when the electromagnetic interference equipment 6 is ventilated and heat-dissipated, the gas can be filtered and dehumidified, so that the gas transported to the protection box 1 can be kept dry. As the air pressure in the protection box 1 increases, the sealing ball 41 can move under the action of the air pressure to release the blockage of the exhaust pipe 39, so that the gas in the protection box 1 can be discharged, and the reset spring 38 is provided to elastically pull the sealing ball 41, so as to ensure that a constant air pressure is maintained in the protection box 1 to avoid excessive gas flow.When the gas is used to cool down and dissipate the heat of the anti-electromagnetic interference device 6, the gas can maintain sufficient contact with the anti-electromagnetic interference device 6, so that the anti-electromagnetic interference device 6 can dissipate the heat more evenly.

[0035] However, as is well known to those skilled in the art, the working principles and wiring methods of the anti-electromagnetic interference device 6 and the drive motor 24 are commonplace, and are conventional means or common knowledge, and will not be elaborated here. Those skilled in the art may make any optional selections according to their needs or convenience.
