[0026] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.
[0027] Please see Figures 1-4 This utility model provides a novel high-frequency online acquisition electronic pressure gauge for wellheads, including a connecting base 1, and a self-cleaning mechanism 2 is provided inside the connecting base 1;
[0028] The self-cleaning mechanism 2 includes an electronic pressure gauge body 201. The top of the electronic pressure gauge body 201 is fixedly connected to the bottom surface of the connecting seat 1. A fixing flange 4 is fixedly connected to the outer surface of the connecting seat 1. Multiple fixing bolts 5 are connected to the internal threads of the fixing flange 4. By relying on the cooperation of the fixing flange 4 and the fixing bolts 5, the connecting seat 1 can be quickly fixed to the wellhead, which increases the convenience during installation and improves the effect during use.
[0029] A liquid storage tank 202 is fixedly connected to the inner wall of the connecting seat 1. A cleaning sleeve 203 is provided on the outer surface of the electronic pressure gauge body 201. The top end of the cleaning sleeve 203 is fixedly connected to the bottom surface of the connecting seat 1. A placement groove 6 is provided inside the fixed flange 4. A sealing gasket 7 is provided inside the placement groove 6. Through the cooperation of the placement groove 6 and the sealing gasket 7, the sealing effect after the connecting seat 1 is connected to the wellhead can be effectively increased, avoiding leakage at the connection and improving safety during mining.
[0030] The cleaning sleeve 203 has multiple cleaning nozzles 204 arranged at equal intervals inside. The upper surface of the liquid storage tank 202 is fixedly connected to a one-way valve 8. The top of the one-way valve 8 passes through the connecting seat 1 and extends to the top of the connecting seat 1. The one-way valve 8 can provide a convenient liquid inlet position for the liquid storage tank 202, which increases the convenience of adding cleaning liquid to the liquid storage tank 202, and at the same time can prevent the cleaning liquid in the liquid storage tank 202 from spilling out.
[0031] An auxiliary water pump 205 is installed inside the liquid storage tank 202. A stabilizing block 9 is fixedly connected to the outer surface of the auxiliary water pump 205. The bottom surface of the stabilizing block 9 is fixedly connected to the inner bottom wall of the liquid storage tank 202. The stabilizing block 9 serves to fix the auxiliary water pump 205, providing a good force-bearing position for the auxiliary water pump 205, increasing the stability of the auxiliary water pump 205 during use, and improving the sensitivity of the device.
[0032] The outlet end of the auxiliary water pump 205 is fixedly connected to a water delivery pipe 206. The bottom end of the water delivery pipe 206 passes through the liquid storage tank 202 and the connecting seat 1 in sequence and is fixedly connected to the top end of the cleaning sleeve 203. The upper surface of the connecting seat 1 is fixedly connected to an intelligent controller 207. The intelligent controller 207 is electrically connected to the auxiliary water pump 205 through a wire. The outer surface of the cleaning sleeve 203 is fixedly connected to a reinforcing ring 10. The top end of the reinforcing ring 10 is fixedly connected to the bottom surface of the connecting seat 1. The reinforcing ring 10 can increase the fixed connection area between the cleaning sleeve 203 and the connecting seat 1, making the connection between the two more secure, preventing the possibility of breakage at the connection after long-term use, and increasing the service life of the device.
[0033] The liquid storage tank 202 is equipped with a monitoring component 3, which includes a water level sensor 301. The bottom surface of the water level sensor 301 is fixedly connected to the inner bottom wall of the liquid storage tank 202. A buzzer 302 is fixedly connected to the upper surface of the connecting seat 1. The water level sensor 301 is electrically connected to the buzzer 302 through a wire. The water level sensor 301 senses the liquid level in the liquid storage tank 202 and sends an electrical signal to the buzzer 302 through the wire when it senses that the liquid level is low. The buzzer 302 then reminds the operator to add liquid in time by making a buzzing sound, which increases the convenience of subsequent maintenance.
[0034] The buzzer 302 is provided with a protective shell 11 on its outer surface. The bottom surface of the protective shell 11 is fixedly connected to the upper surface of the connecting seat 1. The protective shell 11 can provide a good protection for the buzzer 302, prevent the buzzer 302 from being hit by external objects during use, ensure the safety of the buzzer 302, and increase the service life of the device.
[0035] When using this utility model: First, connect the power supply to the electronic pressure gauge body 201, auxiliary water pump 205, intelligent controller 207 and water level sensor 301. Then, add the mixed cleaning solution and neutral solvent into the storage tank 202 through the one-way valve 8. Finally, fix the connecting seat 1 in the wellhead with the fixing flange 4 and fixing bolts 5. At this time, the placement groove 6 and sealing gasket 7 can increase the sealing effect between the connecting seat 1 and the wellhead. Then, the pressure in the wellhead can be monitored through the electronic pressure gauge body 201.
[0036] During the monitoring process, the intelligent controller 207 periodically sends an electrical signal to the auxiliary water pump 205 via a wire, activating it. The pump then uses a water delivery pipe 206 to transport the cleaning fluid and neutral solvent from the storage tank 202 to the cleaning casing 203. Multiple cleaning nozzles 204 evenly spray the solution onto the surface of the electronic pressure gauge body 201, causing impurities to detach under impact and surface tension. This ensures the accuracy of the electronic pressure gauge body 201 during monitoring and prevents contaminants such as crude oil impurities, scale, and silt from adhering to the surface of the gauge body 201, which could lead to decreased measurement accuracy or even equipment malfunction. When the cleaning fluid level in the storage tank 202 falls below the water level sensor 301, the sensor sends a rapid electrical signal to the buzzer 302 via a wire, causing the buzzer to emit a piercing sound, attracting the operator's attention and facilitating the timely addition of cleaning water. This effectively improves the performance of the high-frequency online acquisition electronic pressure gauge at the wellhead.
