Description

Technical Field

[0001] The present invention belongs to the technical field of thrusters, and particularly relates to an underwater thruster with a protection structure. Background Art

[0002] A thruster is a device that converts any form of energy into mechanical energy. It generates thrust by rotating blades or jetting (water). Thrusters are widely used in fields such as ships and aviation, mainly used to propel ships and boats forward. There are various types of thrusters, including propeller thrusters, electric marine thrusters, aviation thrusters, water jet thrusters, etc., and each has its special uses and characteristics.

[0003] There are various types of thrusters. Due to its fast rotation speed and ability to ensure good working efficiency, the propeller is the most common propulsion method.

[0004] The rotation of the propeller is often driven by a motor, and a forward propulsion force is formed under the action of the motor. However, during the rotation process, the propeller is easily affected by the outside world. Once a foreign object hits or wraps around the propeller, the propeller cannot rotate normally or even stops rotating, which will cause the ship to stagnate. Adding a fairing outside the propeller can not only protect the propeller and ensure its normal rotation, but also form a fairing function to a certain extent and ensure the stability of the ship's forward movement. However, simply adding a fairing can only provide a certain degree of protection on the side of the propeller, but cannot protect the front of the propeller. In addition, the head of the traditional thruster is flat, which increases the resistance of underwater forward movement and reduces the power of the thruster to move forward. Summary of the Invention

[0005] To solve the above problems, the primary object of the present invention is to provide an underwater thruster with a protection structure, which can fully protect the propeller and prevent the problem that foreign objects such as waterweeds and garbage are mixed during the use of the thruster and affect the overall propulsion effect.

[0006] Another object of the present invention is to provide an underwater thruster with a protection structure, which has high power and forward stability.

[0007] To achieve the above object, the technical solution of the present invention is as follows.

[0008] An underwater thruster with a protective structure, characterized in that the thruster comprises a support plate, a rotating device and an arc-shaped head. The rotating device includes a motor and a propeller. The motor is connected to the propeller. The propeller is provided with a fairing on the rotating side. The propeller is provided with filter nets on the front side and the rear side. The fairing and the filter nets are detachably connected to form a cover body that wraps the propeller. The arc-shaped head is movably connected to the motor. The arc-shaped head and the fairing are both connected to one side of the support plate. By providing a fairing on the rotating side of the propeller, the diversion of water on the rotating side of the propeller can be realized. At the same time, the fairing can protect the side of the propeller, effectively preventing the propeller from winding and mixing foreign objects such as waterweeds and garbage on the rotating side during the rotation process. By providing filter nets on the front and rear sides of the propeller respectively, the filtering function of the water on the front and rear sides of the propeller can be realized, preventing the propeller from sucking or mixing waterweeds, garbage, etc. from the front side or the rear side during the forward movement. Through the cover body formed by the fairing and the filter nets, the surrounding protection of the propeller can be realized. By setting the arc-shaped head, compared with the flat head, the water resistance during the forward movement is reduced, and the forward power of the thruster is improved. The support plate is used to fix the rotating device and the arc-shaped head. At the same time, it is convenient to fix the thruster on tools such as ships and yachts by using the support plate.

[0009] Further, the support plate extends outwards with arc-shaped protrusions at the front and rear ends respectively, and the support plate is recessed inwards at the left and right ends respectively to form arc-shaped grooves. The arc-shaped head and the fairing are respectively connected to the front and rear ends of the support plate. By providing arc-shaped protrusions at the front and rear ends of the support plate, a sharp water-dividing structure is formed at the front and rear ends, and the arc-shaped protrusions can be used to cut the water during the use of the thruster, reducing the resistance generated by the thruster itself during the use process and increasing the overall power that the thruster can generate. By providing arc-shaped grooves at the left and right ends of the support plate, the flow rate of the water on the side of the support plate is increased, making the thruster smoother in the water and reducing the resistance.

[0010] Further, an auxiliary plate is detachably connected to the support plate, and the support plate and the auxiliary plate are arranged side by side at intervals. By providing the auxiliary plate, the fixation of the thruster to the ship can be realized by using the auxiliary plate. The distance between the auxiliary plate and the support plate actually increases the draft depth of the thruster. Through the detachable connection structure between the auxiliary plate and the support plate, it is possible to flexibly choose whether to install the auxiliary plate or adjust the distance between the support plate and the auxiliary plate according to needs, so as to meet the requirements of different water levels and application scenarios.

[0011] Further, a speed regulation device is provided on the other side of the support plate. The speed regulation device is connected to the motor and is arranged between the support plate and the auxiliary plate. The speed regulation device is provided to adjust the power of the thruster. The speed regulation device is arranged on the side of the support plate, so that the speed regulation device is in contact with water during operation, achieving the function of heat dissipation and temperature reduction of the speed regulation device.

[0012] Further, fixing pieces extend outwards on the side of the speed regulation device. The speed regulation device is detachably connected between the support plate and the auxiliary plate through the fixing pieces. The fixing pieces are provided to facilitate fixing the speed regulation device on the support plate. When the auxiliary plate needs to be provided, the speed regulation device can also use the extended fixing pieces to install and fix the speed regulation device between the support plate and the auxiliary plate.

[0013] Further, fin pieces are provided on the arc-shaped head, and the fin pieces are arranged directly above the arc-shaped head. By adding fin pieces to the arc-shaped head, when the thruster moves forward, the fin pieces are used to cut through the water flow, reducing the resistance of the water and the resistance during travel; at the same time, the fin pieces can make the straight-line forward route of the thruster straight, reducing the probability of left and right swings and increasing the stability of the thruster's forward movement.

[0014] Further, through holes are provided on the support plate, and the through holes are arranged opposite to the position of the speed regulation device. The through holes on the support plate increase the contact area between the speed regulation device and water, making the heat dissipation and temperature reduction effect of the speed regulation device better.

[0015] By adding a fairing and a filter net outside the propeller in the present invention, the protection of all sides of the propeller can be realized, preventing the propeller from sucking in foreign objects such as waterweeds and garbage during use, ensuring the performance of the propeller and the overall stability of the thruster;

[0016] Through the setting of the arc-shaped head, the resistance during the forward movement of the thruster is reduced, and the overall power during the travel of the thruster is improved. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Refer to Figure 1-2As shown in the figure, an underwater thruster with a protective structure according to the present invention includes a support plate 1, a rotating device 2, and an arc-shaped head 3. The rotating device 2 includes a motor 21 and a propeller 22. The motor 21 is connected to the propeller 22. A fairing 221 is provided on the rotating side of the propeller 22. Filter meshes 222 are provided on the front and rear sides of the propeller 22. The fairing 221 and the filter meshes 222 are detachably connected to form a housing that wraps the propeller 22. The arc-shaped head 3 is movably connected to the motor 21. Both the arc-shaped head 3 and the fairing 221 are connected to one side of the support plate 1. By providing the fairing 221 on the rotating side of the propeller 22, the diversion of water on the rotating side of the propeller 22 can be achieved. At the same time, the fairing 221 can protect the side of the propeller 22, effectively preventing foreign objects such as waterweeds and garbage from being entangled and mixed on the rotating side during the rotation of the propeller 22. By providing the filter meshes 222 on the front and rear sides of the propeller 22 respectively, the filtering function of the water on the front and rear sides of the propeller 22 can be achieved, preventing the propeller 22 from sucking in or being mixed with waterweeds, garbage, etc. from the front or rear during the forward movement. Through the housing formed by the fairing 221 and the filter meshes 222, the wrapping protection around the propeller 22 can be achieved. By providing the arc-shaped head 3, compared with a flat head, the water resistance during forward movement is reduced, and the driving force for the forward movement of the thruster is increased. The support plate 1 is used to fix the rotating device 2 and the arc-shaped head 3. At the same time, it is convenient to fix the thruster on tools such as ships and yachts for use by using the support plate 1.

Arc-shaped grooves 12 are recessed inward from the left and right ends of the support plate 1 respectively. The arc-shaped head 3 and the fairing 221 are respectively connected to the front and rear ends of the support plate 1. By providing the arc-shaped protrusions 11 on the front and rear ends of the support plate 1, a sharp water-dividing structure is formed at the front and rear ends, and the arc-shaped protrusions 11 can be used to cut the water during the use of the thruster, reducing the resistance generated by the thruster itself during use and increasing the overall driving force that the thruster can generate. By providing the arc-shaped grooves 12 at the left and right ends of the support plate 1, the flow rate of the water on the side of the support plate 1 is increased, making the thruster smoother in water and reducing the resistance.

[0022] Among them, an auxiliary plate 13 is detachably connected to the support plate 1, and the support plate 1 and the auxiliary plate 13 are arranged side by side at intervals. Through the arrangement of the auxiliary plate 13, the fixation of the thruster to the ship can be achieved by using the auxiliary plate 13.

Through the detachable connection structure between the auxiliary plate 13 and the support plate 1, it is possible to flexibly select whether to install the auxiliary plate 13 or adjust the distance between the support plate 1 and the auxiliary plate 13 according to needs, so as to meet the requirements of different water levels and application scenarios.

[0024] Among them, a fixing piece 141 extends outward from the side of the speed regulation device 14. The speed regulation device 14 is detachably connected between the support plate 1 and the auxiliary plate 13 through the fixing piece 141. The setting of the fixing piece 141 facilitates the fixation of the speed regulation device 14 on the support plate 1. When it is necessary to set the auxiliary plate 13, the speed regulation device 14 can also use the extended fixing piece 141 to install and fix the speed regulation device 14 between the support plate 1 and the auxiliary plate 13.

[0025] Among them, fin pieces 31 are arranged on the arc-shaped head 3, and the fin pieces 31 are arranged directly above the arc-shaped head 3. By adding the fin pieces 31 to the arc-shaped head 3, when the thruster is moving forward, the fin pieces 31 are used to cut through the water flow, reducing the resistance of the water and the resistance of movement; at the same time, the fin pieces 31 can make the straight-line forward route of the thruster straight, reducing the probability of left and right swing and increasing the stability of the thruster's forward movement.

[0026] Among them, a through hole 15 is arranged on the support plate 1, and the through hole 15 is arranged opposite to the position of the speed regulation device 14.
