Description

Technical Field

[0001] This utility model relates to the field of underwater propulsion technology, and more specifically to an underwater propulsion device with pressure compensation. Background Technology

[0002] The function of an underwater propulsion system is to convert the energy carried by an underwater vehicle or equipment into mechanical energy, propelling it forward in the water. It effectively reduces water resistance, provides powerful and sustained thrust, enabling divers, underwater robots, and other equipment to move faster underwater, expand their operational range, reduce energy consumption and air consumption, and extend their underwater endurance. It can also be used for underwater search and rescue, surveying, and other missions.

[0003] In underwater operating environments, water pressure changes significantly with diving depth. During operation, the varying pressure on the outer shell at different depths alters the stress state of internal components, potentially affecting normal operation. Excessive internal pressure can damage key internal components. In underwater environments, especially near the bottom or in areas rich in aquatic vegetation, the propeller is easily entangled in weeds. As the propeller rotates, weeds gradually become entangled on the impeller or other rotating parts. Once entangled, the propeller becomes like a rope, unable to rotate properly. As the entanglement worsens, the impeller may become jammed, preventing the propeller from turning. In this situation, the submersible loses its power source, drifts with the current, and cannot move according to operator commands, severely impacting its normal function. Utility Model Content

[0014] This invention, by incorporating a pressure compensation component, facilitates the automatic adjustment of the internal pressure of the thruster, maintaining its balance with the external water pressure. When the submersible descends to a deeper position, the external water pressure increases, and the component can increase the internal pressure of the thruster through an appropriate mechanism. This prevents problems such as seal failure and component deformation caused by excessive internal and external pressure differences, which helps maintain the normal operation of the thruster, ensures the stability of thrust output, and enables the submersible to travel along a predetermined trajectory and speed.

The rubber pad 102 is fixedly installed on the outer wall of the housing 101. The high-precision water pressure sensor 103 is distributed in a ring and fixedly installed on the outer wall of the rubber pad 102. The booster pump 104 is fixedly installed at the bottom inside the housing 101. The exhaust pipe 105 is fixedly connected to the output end of the booster pump 104. The housing 101 is made of aluminum alloy, which can effectively reduce the overall weight of the thruster and improve the maneuverability and flexibility of the underwater equipment. It has high yield strength and tensile strength, which meets the requirements of the underwater high-pressure environment for the structural strength of the housing. The pressure compensation component 1 is provided so that the high-precision water pressure sensor 103 can detect the water pressure around the device and send the detected signal to the control component 2. After receiving the signal, the control component 2 judges the pressure value and controls the booster pump 104 to start working based on the judged data to perform pressure compensation activities for the internal space of the housing 101.

[0026] Reference Figure 2 , Figure 3 The control component 2 includes an isolation plate 201, a controller 202 and a partition plate 203, wherein the isolation plate 201 is disposed inside the outer shell 101, the controller 202 is fixedly installed on the outer wall of the isolation plate 201, and the partition plate 203 is fixedly installed on the top of the outer shell 101.

[0027] Reference Figure 2 , Figure 6 The anti-winding component 3 includes a fixed shell 301, a vertical baffle 302, an upper sealing ring 303, and a lower sealing ring 304. The fixed shell 301 is fixedly installed above the partition 203. One end of the vertical baffle 302 is fixedly connected to the outer wall of the fixed shell 301, and the other end is fixedly connected to the bottom of the protective component 4. The upper sealing ring 303 is located above the inner wall of the fixed shell 301, and the lower sealing ring 304 is located below the inner wall of the fixed shell 301. The anti-winding component 3 facilitates the movement of components during device operation. After the propulsion operation, there will inevitably be weeds or other impurities underwater. The vertical baffle 302 can effectively block and intercept these impurities, preventing them from getting tangled on the drive shaft of the protective component 4 and affecting the propulsion operation of the device. The upper sealing ring 303 and the lower sealing ring 304 ensure the dryness and cleanliness of the internal mechanical parts, thereby extending the service life of the equipment. At the same time, they can also enhance the airtightness of the propeller, reduce energy loss, and improve propulsion efficiency. In addition, they can also protect the equipment from corrosion and pollution, ensuring the stability and safety of underwater operations.

[0028] Reference Figure 2 , Figure 4The protective component 4 includes a lower ring 401, an upper housing 402, a drive motor 403, a rotating shaft sleeve 404, and blades 405. The lower ring 401 is fixedly installed above the vertical baffle 302. The upper housing 402 is threadedly connected to the lower ring 401. The drive motor 403 is fixedly installed at the bottom of the partition 203. The output end of the drive motor 403 movably passes through the partition 203 and the vertical baffle 302.

The blades 405 are distributed in a ring and fixedly installed on the outer wall of the rotating shaft sleeve 404.

[0029] The working principle of this utility model:

[0030] First, the workers thread the upper housing 402 and the lower ring 401 onto the upper part of the housing. After installation, the device is installed under the device that needs to be pushed, and the device can then start working.

[0031] Secondly, as the device descends, the water pressure varies at different depths. The high-precision water pressure sensor 103 then activates, detecting the water pressure around the device and converting the detected data into a pressure signal, which is transmitted to the controller 202. Upon receiving the pressure signal, the controller 202 calculates the required pressure compensation value based on a preset pressure compensation algorithm. Then, the controller 202 sends a command to the booster pump 104 inside the pressure compensation chamber. Upon receiving the command, the booster pump 104 begins operation, providing a certain pressure to the inside of the device. The outer shell 101 is made of aluminum alloy, which effectively reduces the overall weight of the thruster. The quantity enhances the maneuverability and flexibility of underwater equipment. It possesses high yield strength and tensile strength, meeting the structural strength requirements of the high-pressure underwater environment. The output end of the drive motor 403 drives the rotating shaft sleeve 404 and the blade 405 to rotate, thereby providing propulsion for the device. The lower sealing ring 304 and the upper sealing ring 303 effectively prevent water from entering the device, thus effectively avoiding water ingress into internal components and affecting the device's operation. Underwater, there are inevitably weeds or other impurities. The vertical baffle 302 can effectively isolate and intercept these impurities, preventing them from getting tangled on the drive shaft of the protective component 4, thereby affecting the device's propulsion.
