Description

Technical Field

[0001] This utility model relates to the field of controller technology, and in particular to a pressure controller. Background Technology

[0002] In fields such as marine development, underwater exploration, and diving equipment, precise buoyancy adjustment is a core requirement for ensuring stable equipment operation and operational safety. Pressure controllers, as key devices for achieving this function, directly impact the operational efficiency and reliability of underwater systems. Current mainstream buoyancy adjustment technologies are mainly divided into two categories: active and passive. Passive technologies often rely on fixed buoyancy materials or elastic elements with adjustable volumes, while active technologies use motor-driven pistons or pumps to deliver fluids or gases, changing the volume of liquid displaced by the device to achieve dynamic buoyancy adjustment. Both technologies are applied in various underwater scenarios, providing fundamental support for the normal operation of underwater equipment. Developing pressure controllers adaptable to more scenarios is an important research direction in the current underwater technology field.

[0003] When using the above-mentioned technology, the following technical problems were found in the existing technology: Some traditional devices use airbag inflation or deflation, but the pressure resistance of the airbag is limited, and it is easily damaged in deep underwater environments, resulting in a short service life. Moreover, the adjustment process is easily affected by external factors such as water flow, resulting in poor stability. In addition, most existing pressure regulating devices have complex structures and are cumbersome to operate, and have low adaptability to some miniaturized and lightweight equipment, making it difficult to meet the needs of modern equipment development towards miniaturization, high precision, and high stability. Therefore, we designed a pressure controller to provide an alternative technical solution to the above-mentioned technical problems. Utility Model Content

The power module uses a lithium battery pack, which has the characteristics of large capacity, light weight, and good charging and discharging performance. It can meet the power requirements of the device for long-term operation and facilitates the miniaturization design of the device.

[0044] The buoyancy ball 9 is made of high-strength polytetrafluoroethylene (PTFE) material. PTFE material has excellent corrosion resistance, high pressure resistance and low density characteristics, which can be used for a long time in different liquid environments without deformation or damage due to excessive external pressure, ensuring the service life and buoyancy adjustment effect of the buoyancy ball.

[0045] Motor 14 is a stepper motor. Stepper motors have the advantages of high control precision and stable operation.

[0048] This utility model has a simple structure, small size and light weight. Its size and parameters can be adjusted according to the needs of different equipment. It is suitable for various miniaturized and lightweight underwater detection equipment, underwater operation equipment and floating body equipment, and has a wide range of applications.

[0049] The water tank 1 of this device is made of stainless steel, which provides good protection for the internal components and prevents them from being corroded by the external liquid environment. The buoyancy ball 9 and other components are made of high-quality materials that are wear-resistant, corrosion-resistant and pressure-resistant, which greatly extends the service life of the device.

[0050] The controller 2 of this device uses a high-performance microcontroller, which can quickly process the signals transmitted by the pressure sensor 12 and generate motor control signals in a timely manner. The motor 14 responds quickly and can quickly adjust the buoyancy, ensuring that the equipment can adapt to different working environments in a timely manner.

[0051] The operation of the pressure controller provided by this utility model is as follows: The user installs the buoyancy adjustment device inside the water tank 1. According to the working requirements of the equipment, the user presets the pressure and buoyancy correspondence in the controller, that is, different pressure values ​​correspond to the required buoyancy. At the same time, according to the initial buoyancy requirement, the user adjusts the initial position of the plumb bob on the active rod and fixes it with the locking bolt. The user powers on the water pump 4, which fills the water tank 1 with external water. The water can generate buoyancy on the buoyancy ball 9, and the pressure sensor 12 can detect the water pressure inside the water tank 1. When the water pressure exceeds the preset value, the pressure sensor 12 sends a signal to the controller 2, and the controller 2 sends a signal to the motor 14. The output end of the motor 14 drives the worm gear 15 to rotate. Since the bottom side of the worm gear 15 is meshed with the worm wheel 16, the rotation of the worm gear 15 drives the worm wheel 16 to rotate, which in turn causes the screw 17 to rotate. A movable plate 18 is connected to the outer thread, so that the rotation of the screw 17 drives the movable plate 18 to move, which in turn drives the gravity weight 19 to move, thereby adjusting the distance of the power arm. This adjusts the buoyancy of the buoyancy ball 9, which moves upward under the action of buoyancy. The movement of the buoyancy ball 9 drives the blocking shaft 10 to move, so that the blocking shaft 10 can generate relative movement inside the water flow screen column 11. Water can flow out of the water tank 1 from the inner screen hole of the water flow screen column 11, thereby adjusting the pressure inside the water tank 1. When the pressure of the internal water source is less than the predetermined value, the pressure sensor 12 can send a signal to the motor 14, and the motor 14 rotates in the opposite direction, causing the gravity weight 19 to move in the opposite direction, thereby adjusting the distance of the power arm again. Through a series of designs, this utility model realizes the dynamic balance adjustment of water supply pressure, and has technical advantages such as precise adjustment, convenient maintenance, energy saving and environmental protection. It is suitable for pressure control scenarios of water storage equipment for urban and rural residents.
