Abstract
Description
Technical Field
[0001] This utility model relates to the field of buoyancy adjustment technology, and more specifically to a handheld underwater vehicle buoyancy adjustment device. Background Technology
[0002] Ocean resources are abundant and possess significant economic and military value, making them a new hotspot for competition among nations worldwide. With the increasing development and utilization of the ocean, more and more underwater equipment is being deployed. Underwater aircraft, as one type, need to possess excellent buoyancy adjustment capabilities to adapt to different underwater environments, achieving stable suspension, surfacing, and diving functions to better accomplish tasks such as detection and observation.
[0003] Existing underwater gliders or underwater vehicles mostly use hydraulic buoyancy adjustment devices, which rely on components such as oil pumps, cylinders, and oil bladders. These devices are complex and bulky, resulting in a large overall weight and space occupation. This makes it difficult for operators to control the entire device and poses certain safety hazards. They are especially unsuitable for small, portable underwater vehicles. Furthermore, most existing underwater vehicles are equipped with a single buoyancy adjustment device, which cannot accurately adjust buoyancy deviations. In case of emergencies, the ascent or descent rate is slow, and it is necessary to wait for the buoyancy adjustment device to introduce or expel water before the buoyancy of the underwater vehicle can be changed. The buoyancy adjustment efficiency of the device is low. Utility Model Content

[0023] The technical solution of this utility model will be clearly and completely described below with reference to the accompanying drawings. In addition, the forms of the various structures described in the following embodiments are merely illustrative. The handheld underwater vehicle buoyancy adjustment device involved in this utility model is not limited to the structures described in the following embodiments. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0024] Reference Figure 1-6 This utility model provides a handheld underwater vehicle buoyancy adjustment device, including a body component 1, an adjustment component 2 is provided inside one side of the body component 1, a drive component 3 is provided outside the adjustment component 2 between the two sides of the body component 1, a flow guide component 4 is installed on one side of the drive component 3, and a control component 5 is provided inside the body component 1.
[0025] Reference Figure 1-3 and Figure 6The body assembly 1 includes a float box 101, a fixed cavity 102, a connecting rod 103, a grip rod 104, and a water tank 105. The float box 101 has a symmetrical design, and one side of the float box 101 is designed to reduce water flow resistance. The fixed cavity 102 is located inside the right side of the float box 101. The connecting rod 103 is symmetrically sleeved between the two float boxes 101, specifically configured as a fixed sleeve. The grip rod 104 is fixedly installed inside the fixed cavity 102. The water tank 105 is located inside the float box 101, which allows the operator to put their entire hand inside the fixed cavity 102 and hold the grip rod 104, making it easier to control the direction of the underwater vehicle. At the same time, when the hand grips the grip rod 104 tightly, the fixed cavity 102 will cover the entire hand, so that the underwater vehicle will not easily fall out of the operator's hand.
[0026] Reference Figure 3-4 and Figure 6 The adjustment assembly 2 includes an adjustment motor 201, a first helical gear 202, a roller shaft 203, and a second helical gear 204. The adjustment motor 201 is nested inside one side float 101, and the output shaft of the adjustment motor 201 is fixedly connected to the first helical gear 202 via a coupling. The roller shaft 203 is rotatably connected between the two floats 101. The second helical gear 204 is fixedly connected to one end of the roller shaft 203, located inside one side float 101, and meshes with the first helical gear 202. This facilitates the starting of the adjustment motor 201. The output shaft of the adjustment motor 201 drives the transmission shaft to rotate, which in turn drives the first helical gear 202 to rotate. The first helical gear 202 then drives the meshing second helical gear 204 and the roller shaft 203 to rotate, thereby controlling the tilt angle of the drive assembly 3 and the guide assembly 4 and further improving the operating speed of surfacing or diving.
[0027] Reference Figure 1-4 The drive assembly 3 includes a drive cabin 301, fins 302, a drive motor 303, and a vortex vane 304. One side of the drive cabin 301 is arc-shaped to reduce water resistance and increase the speed of the underwater vehicle. The drive cabin 301 is fixedly sleeved on the outside of the roller shaft 203 and located between the two float boxes 101. Fins 302 are evenly arranged on the top and bottom of the drive cabin 301. The drive motor 303 is evenly installed inside the drive cabin 301, and the output shaft of the drive motor 303 is fixedly sleeved with the vortex vane 304 through a coupling, which facilitates the starting of the drive motor 303. The output shaft of the drive motor 303 drives the transmission shaft to rotate, and the transmission shaft drives the vortex vane 304 to rotate. Under the action of the rotation of the vortex vane 304, the water flow is pushed to make the device run underwater.
[0028] Reference Figure 1-3 and Figure 5The flow guiding assembly 4 includes a flow guide shroud 401, a water inlet 402, and flow guide vanes 403. The flow guide shroud 401 is evenly arranged on one side of the drive compartment 301, located outside the vortex vane 304. The water inlet 402 is annularly opened on one side surface of the drive compartment 301. The flow guide vanes 403 are evenly arranged on the inner wall of the flow guide shroud 401, which facilitates the water flow to enter the flow guide shroud 401 through the water inlet 402. Driven by the rotating vortex vane 304, the flow guide vanes 403 guide the water flow, so that the water flow is output to the outside in a straight line, thereby improving the output efficiency of the underwater vehicle.
[0029] Reference Figure 1-3 The control component 5 includes a one-way valve 501 and a pressure pump 502. The specific model of the one-way valve 501 is D705-22-02, which is characterized by its small size, stable flow, pressure resistance and waterproofness. The one-way valve 501 is fixedly installed on the bottom of one side of the water storage tank 105. The pressure pump 502 is symmetrically installed on the top and bottom of one side of the float box 101. This facilitates the control of water intake and drainage of the water storage tank 105 through the one-way valve 501 and the pressure pump 502. At the same time, it works with the adjustment component 2 to further control and adjust the buoyancy of the underwater vehicle.
[0030] The working principle of this utility model:
[0031] First, the operator can put their entire hand inside the fixed cavity 102 and hold the grip bar 104 to control the direction of the underwater vehicle. When the hand grips the grip bar 104 tightly, the fixed cavity 102 will cover the entire hand, so that the underwater vehicle will not easily fall out of the operator's hand.
[0032] Next, start the drive motor 303. The output shaft of the drive motor 303 drives the transmission shaft to rotate. The transmission shaft drives the vortex 304 to rotate. Under the action of the rotation of the vortex 304, the water flow is pushed to make the device run underwater. At the same time, the direction of the device is controlled by both hands.
[0033] Finally, the water tank 105 is controlled to enter and exit water by one-way valve 501 and pressure pump 502 to complete the submersion and ascent. If it is necessary to increase the ascent or submersion speed, the regulating motor 201 is started. The output shaft of the regulating motor 201 drives the transmission shaft to rotate. The transmission shaft drives the first helical gear 202 to rotate. The first helical gear 202 drives the second helical gear 204 and roller 203 to rotate, thereby controlling the tilt angle of the drive assembly 3 and the guide assembly 4 to further increase the operating speed of surfacing or submerging.
