Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of aerodynamic ships, in particular to an aerodynamic catamaran suitable for a tidal flat environment. Background Art
[0002] The mudflat environment refers to the tidal zone between the high and low tide levels of coastal tides, as well as the beaches between the normal water level and flood level of rivers and lakes.
[0003] Currently, in the tidal flat environment, workers mainly rely on wearing ordinary protective clothing for monitoring and research, and personnel safety cannot be guaranteed. In addition, tidal flat operations such as resource exploration and environmental monitoring are carried out by manually driving hovercraft, but they are more susceptible to damage from sharp objects and have too high maintenance costs. In addition, the functions and usage scenarios of robots currently used in marine tidal flat environments are relatively monotonous, and they all have limitations to varying degrees. Various costs and energy consumption are high. In addition, they cannot efficiently switch between water and land environments autonomously. Utility Model Content
[0004] The purpose of the present utility model is to solve at least one of the technical problems existing in the prior art, and to provide an aerodynamic catamaran suitable for mudflat environments. By moving the propulsion system from below the waterline to above the deck, abundant and renewable aerodynamic sources are used instead of water propulsion, thereby reducing harmful substance emissions and having a higher cruising speed. The bottom design of the hull has strong adaptability to complex terrain and high driving stability, which greatly expands its range of activities. The power lift wings above the deck can rectify the irregular moving airflow in front of the air propulsion device, and can accelerate the airflow above the power wings, causing a pressure difference between the upper and lower surfaces of the wings, providing a certain lift for the hull, reducing navigation resistance and energy consumption. The air lift effect can also convert part of the water surface resistance into air resistance, which can effectively reduce the resistance during overall movement and improve propulsion efficiency. In addition, the double hull structure can improve the movement posture, and has the advantages of good speed, excellent wave resistance and low stall in waves, solving the problem of difficulty in starting due to silt subsidence.
[0005] The present invention also provides an aerodynamic catamaran suitable for a mudflat environment, comprising: a deck, the lower surface of the deck being fixedly connected to two hulls, both hulls being provided with a hard air cushion chamber, the upper surface of the deck being fixedly connected to a control box body, the upper surface of the deck being fixedly connected to two pads, the upper surfaces of the pads being fixedly connected to windbreaking plates, the upper surfaces of the windbreaking plates being fixedly connected to power lift wings, the upper surface of the deck being fixedly connected to four mounting seats, the four mounting seats being provided with through holes, the inner walls of the through holes being provided with air thrust devices, and the air thrust devices being located behind the power lift wings.
[0006] According to the utility model, an aerodynamic catamaran suitable for a tidal flat environment, the air propulsion device includes: a motor housing, a bracket, a brushless motor, and ducted fan blades. The motor housing is fixedly connected to the inner wall of the through hole, the bracket is fixedly connected to the inner wall of the motor housing, the brushless motor is fixedly connected to the inner surface of the bracket, and the ducted fan blades are fixedly connected to the output end of the brushless motor.
[0007] According to the aerodynamic catamaran suitable for a mudflat environment described in the utility model, the lower surface of the hull is fixedly connected to a bottom armor.
[0008] According to the aerodynamic catamaran suitable for a mudflat environment described in the utility model, a lamp holder is fixedly connected to the front surface of the control box body, and a spotlight is fixedly connected to the inner surface of the lamp holder.
[0009] Beneficial effects
[0010] 1. Compared with the existing technology, this aerodynamic catamaran suitable for mudflat environments moves the propulsion system from below the waterline to above the deck, using abundant and renewable aerodynamic sources instead of water propulsion, reducing harmful substance emissions and achieving a higher cruising speed. The hull bottom design has strong adaptability to complex terrain and high driving stability, greatly expanding its range of activities. The powered lift wings above the deck can rectify the irregular airflow in front of the air propulsion device and accelerate the airflow above the powered wings, creating a pressure difference between the upper and lower wings, providing a certain amount of lift for the hull, reducing navigation resistance and energy consumption. The air lift effect can also convert part of the water surface resistance into air resistance, which can effectively reduce the resistance during overall movement and improve propulsion efficiency. In addition, the double hull structure can improve the movement posture, has good speed, excellent seakeeping and low stall in waves, and solves the problem of difficulty in starting due to silt sinking.
