Description

Technical Field

[0001] The invention relates to the technical field of wireless control, and in particular to a remote pressure control device for a pressure regulating station. Background Art

[0002] The remote pressure control device of the pressure regulating station is used in natural gas, oil and other pipeline systems, especially in gas supply systems, to ensure stable pressure and safe operation by remotely monitoring and automatically controlling the working status of the pressure regulating equipment. Its main purpose is to automatically adjust the pressure according to the pressure change requirements in the pipeline network to avoid pipeline network failures or safety accidents caused by excessively high or low pressure.

[0003] The remote pressure control device of the pressure regulating station usually has the following functions:

[0004] Real-time pressure monitoring: The device can monitor the pressure of the pressure regulating station or pipeline in real time and transmit the data to the remote control center. In this way, the operator can check the pressure changes at any time.

[0005] Remote control regulating valve: Through the remote system, the regulating valve (such as pressure regulating valve, check valve, etc.) of the pressure regulating station is controlled to automatically adjust the pressure in the pipeline and keep it stable within the preset safety range.

[0006] Alarm and fault diagnosis: When the pressure exceeds the set range or the equipment fails, the device can automatically alarm and transmit the alarm information to the remote monitoring center. At the same time, it can perform simple fault diagnosis to help staff locate the problem.

[0007] Data recording and analysis: The device will record pressure changes, the status of the control valve and other key parameters, and provide them to management personnel for later analysis and optimized operation.

[0008] Automatic regulation and manual intervention: When the pressure is unstable or there is a problem in the system, the pressure regulator can automatically adjust to keep the pressure within the set range. At the same time, the operator can manually intervene in the control as needed.

[0009] Remote maintenance and upgrade: Through the remote communication function, the equipment can be remotely maintained and the software upgraded, avoiding on-site manual intervention.

[0010] How it works

[0011] Pressure sensor: The device is equipped with a pressure sensor to measure the pressure of the pipeline in real time. When the pressure sensor detects abnormal pressure, it transmits the data to the remote control system.

[0012] Remote control system: The remote control center obtains pressure data through monitoring software and controls pressure according to the set standards. If the pressure is too high or too low, the system will automatically issue an adjustment command to control the opening of the regulating valve and adjust the gas or oil supply pressure.

[0013] Actuator: According to the control instructions, the actuator (such as electric valve, regulating valve, etc.) will adjust the pressure to ensure the stability of the gas supply pressure.

[0014] Communication system: The equipment in the voltage regulating station transmits data to the control center in real time through wireless communication, optical fiber communication or other transmission methods. The control center can send instructions to the voltage regulating device to make adjustments as needed.

[0015] Advantages of Remote Pressure Control Devices

[0016] Improve operational efficiency: Remote monitoring and control can grasp the operating status of the pressure regulating station in real time, reduce the burden on on-site operators, and improve regulation efficiency.

[0017] Reduce manual intervention: Through automated control, the risk of manual intervention and misoperation can be reduced, and operating costs can be reduced.

[0018] Ensure pipeline network safety: The remote pressure control device can detect abnormal conditions in time and take measures to ensure that the pressure of the pipeline system is within a safe range and prevent accidents.

[0019] Data accumulation and analysis: A large amount of operating data can be collected and analyzed to improve the management level and operation optimization of the entire pipeline system.

[0020] Improve remote emergency response capabilities: Through the remote system, timely responses can be made to failures or abnormal situations, reducing on-site processing time and improving emergency response capabilities.

[0021] Application Scenario

[0022] Natural gas pressure regulating station: In the process of natural gas transmission, the pressure regulating station is a key facility for controlling the gas transmission pressure. The remote pressure control device can ensure the stability of gas pressure and avoid fluctuations that may cause unstable user use or equipment damage.

[0023] Oil pipeline system: In the process of oil transportation, it is very important to maintain a certain pressure. Especially in the case of long pipelines or complex geographical conditions, remote pressure control devices are particularly important.

[0024] Urban water supply and heating systems: Remote pressure control devices can be used for pressure regulation and control of public infrastructure such as urban water supply systems and heating systems.

[0025] The Chinese patent discloses: a wireless controller, patent application number: 202020141443.3, the patent "installation bracket, the back of the mounting bracket is provided with an adhesive portion, and the mounting bracket is provided with a first magnet; a controller PCB board, the controller PCB board is provided with a control module and a wireless communication module; a battery, electrically connected to the controller PCB board; a control panel, electrically connected to the controller PCB board, for operating the control module; a main shell, the main shell is provided with a accommodating cavity for accommodating the controller PCB board and the battery, the front end face of the cavity is provided with an opening for installing the control panel, the rear wall of the main shell is provided with a second magnet that can be adsorbed with the first magnet, and the main shell is adsorbed and fixed to the mounting bracket by the second magnet".

[0026] However, when the equipment is in use, the mounting bracket can be connected to the wall through the adhesive part. In this way, when the installation location of the bracket is changed, the adhesive surface will gradually become loose, the adhesion effect will gradually deteriorate, and it is not conducive to moving the bracket. For this reason, we propose a remote pressure control device for the pressure regulating station. Summary of the invention

[0027] The present invention mainly solves the technical problems existing in the above-mentioned prior art and provides a remote pressure control device for a pressure regulating station.

[0034] The present invention provides a remote pressure control device for a pressure regulating station. It has the following beneficial effects:

[0035] 1. Efficient and stable adsorption and fixing mechanism: The remote pressure control device for the pressure regulating station of the present invention adopts a fixing method combining a suction cup and magnetic adsorption, which has higher flexibility and durability than the traditional adhesive bonding method. The design of the suction cup allows the device to be quickly disassembled and reinstalled when needed without affecting its adsorption effect and stability. At the same time, the introduction of magnetic adsorption makes it less likely for the first shell to loosen or shift during long-term use, thereby significantly improving the service life and operational safety of the equipment.

[0036] 2. Convenient installation and removal: Compared with the traditional pasting method, the remote pressure control device for the pressure regulating station of the present invention adopts a suction cup fixing method, which makes the installation and removal process of the equipment easier. The user can easily remove or place the device from the wall or the installation base through simple manual operation. Different from the adhesive surface bonding method, the suction cup design avoids the risk of loosening and aging of the adhesive surface over time, greatly improving the maintainability of the equipment.

[0037] 3. Space saving and optimization of on-site management: The design of the device takes into account space saving and optimization of on-site management. The base 14 adopts the combination of grooves and card slots, which can achieve a compact layout when stored, making it easy to place and find. This design not only saves physical space, but also reduces the site area occupied by the equipment, which helps to improve the work efficiency and management level on site. In addition, the equipment can be used repeatedly and has a long service life, thereby reducing the frequency of equipment replacement and related costs.

[0038] 4. Strong adaptability and multi-scenario application: Since the present invention adopts a combination of suction cups and magnetic adsorption, the device can adapt to different types of wall surfaces and installation environments. Whether it is a relatively smooth metal surface or a relatively rough brick wall, the suction cup can achieve effective adsorption, and the device does not require any special tools when moving or reinstalling, ensuring the high adaptability of the device in various scenarios. Such a design provides a wide range of application scenarios for the device, not only limited to pressure regulating stations, but can also be widely used in other pipeline systems that require remote control.

[0039] 5. Enhanced safety and reliability: The device of the present invention is designed with a wedge-shaped structure on the inner wall of the pipe, and precise limit control is achieved through a rubber piston. This design can prevent any deviation or sliding of the device during operation, thereby reducing safety hazards caused by equipment failure. The combination of the card block and the card slot, and the stability of the magnetic adsorption, enable the first shell 11 to always maintain the best working state, ensuring safety and reliability during long-term operation.

[0040] 6. Long service life and low maintenance cost: The remote pressure control device for the pressure regulating station of the present invention adopts durable materials and structural design to ensure its long service life. The combination of suction cup and magnetic adsorption avoids the aging and falling off of traditional adhesive materials, greatly reducing the maintenance frequency and replacement cost of the equipment.

[0051] A remote pressure control device for a pressure regulating station, such as Figure 1-Figure 4As shown, the first shell 11 has two groups of symmetrically distributed blocks 13 fixed to the side wall of the first shell 11, a base 14 is provided at the bottom end of the first shell 11, a groove 15 adapted to the size of the first shell 11 is provided at the bottom end of the base 14, and two symmetrically distributed card slots 16 are provided on the inner wall of the groove 15, and the two card slots 16 are engaged with the two groups of first magnets 12, and two second shells 18 are fixed to the side wall of the base 14, and the side walls of the two second shells 18 are both provided with hoses 19, and the two ends of the two second shells 18 are separated from each other. A pipe 21 is fixed to each of the two second housings 18, and a first through hole 22 is provided at both ends of the two second housings 18 that are separated from each other. The two second housings 18 are slidably connected to a cross bar 24 through the first through hole 22. A lifting ring 23 is fixed to both ends of the two cross bars 24 that are separated from each other. A piston 25 that slides inside the pipe 21 is fixed to both ends of the two cross bars 24 that are opposite to each other. A hose 19 is fixed to one end of the two second housings 18 that is close to the suction cup 20. The two second housings 18 are fixed to the suction cup 20 through the hose 19. The two second housings 18 are connected to the suction cup 20 through the hose 19. The first housing 11 is connected to the suction cup 20 through the hose 19, the first magnet 12 is fixed to the side wall of the first housing 11, the second magnet 17 adsorbed to the first magnet 12 is fixed to the inner wall of the groove 15, a sponge pad is arranged at the bottom of the inner wall of the groove 15, and a second through hole is provided at the end of the groove 15 away from the second magnet 17. By adsorbing the suction cup 20 to the wall, the two rings 23 are manually moved in opposite directions. At this time, the two cross bars 24 are both located in the pipe 21 and slide, thereby driving the two pistons 25 to slide on the inner walls of the two pipes 21, so that the suction cup 20 is more closely adsorbed to the wall through the hose 19 and the second housing 18. The wedge shape of the inner wall of the pipe 21 plays a fixed limiting effect. The cooperation between the card slot 16 and the card block 13 plays a limiting role, which is convenient for the first housing 11 to be inserted into the base 14. Through the adsorption between the second magnet 17 and the first magnet 12, the first housing 11 is further fixed to prevent the first housing 11 from shaking due to force majeure, and it is more stable to use.

[0052] Working principle of the present invention:

[0053] Step 1: Working principle of base fixing and adsorption device

[0054] In the remote pressure control device for a pressure regulating station of the present invention, the placement and fixing process of the first housing 11 is completed by the adsorption force between the suction cup 20 and the wall or other objects. By closely contacting the suction cup with the wall surface and relying on the strong adsorption function of the suction cup, the entire base 14 is firmly fixed at the designated position, thereby ensuring the stability of the device.

[0055] Stability of base adsorption: Different from the traditional adhesive surface adhesion method, the present invention uses a suction cup as a fixing method, which can quickly and easily fix the base 14 to the wall by adsorption. This method can not only achieve rapid disassembly and installation, but also compared with traditional bonding technology, the adsorption force of the suction cup is more stable and can be used repeatedly. The design of the suction cup 20 allows the base 14 to adapt to different installation environments in different usage scenarios, thereby providing higher adaptability and flexibility.

[0056] Step 2: Interaction between the piston and the inner wall of the pipe

[0057] When the operator manually pulls the two lifting rings 23 to make the two cross bars 24 move in opposite directions, the two pistons 25 in the pipe 21 begin to slide on the inner wall of the pipe 21. The inner wall of the pipe 21 is designed to be wedge-shaped, which makes the two pistons gradually forced to get stuck in the wedge-shaped groove of the inner wall of the pipe during the sliding process, thereby gradually increasing the friction with the inner wall of the pipe, forming a stable limiting effect. At this time, the design of the piston 25 as an elastic rubber material enables it to withstand large pressure changes, and realizes the limiting effect through friction to prevent excessive sliding and equipment position deviation.

[0058] Through the adsorption effect of the hose 19, the sliding of the piston is not only controlled, but the hose also generates further adsorption force during operation, thereby enhancing the close connection between the suction cup 20 and the wall. In this way, the adsorption force of the hose can enhance the fixation between the suction cup and the object to a certain extent, achieve a stronger adsorption effect, and greatly improve the stability of the entire device.

[0059] Step 3: Matching of card block and card slot and magnetic adsorption

[0060] On both sides of the pipe 21, the first housing 11 is provided with symmetrically distributed blocks 13, and the groove 15 of the base 14 is provided with corresponding slots 16. The cooperation of these blocks 13 and slots 16 can not only help to accurately locate the position of the first housing 11, but also effectively avoid the lateral sliding of the first housing. Through this structural design, the first housing 11 can work stably in a fixed position to avoid displacement caused by external factors.

[0061] In addition, the stability of the first shell is further enhanced by the magnetic adsorption between the first magnet 12 and the second magnet 17. The introduction of the magnetic adsorption effect ensures that the first shell will not be affected by external interference or vibration during installation and use. Magnetic adsorption can not only prevent the shell from shaking, but also ensure that the device is fixed more reliably.

[0062] Step 4: The coordinated work of the whole device

[0063] Through the coordinated work of the above-mentioned components, the remote pressure control device for the pressure regulating station of the present invention can achieve fast and stable installation and removal operations. The design of each component has been carefully considered to ensure adaptability and long-term stability in different industry applications.

[0064] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments.
