Description

A self-propelled carrier with fixed double propellers

Technical field:

The utility model relates to a water craft, in particular to a self-propelled carrier with simple structure and good stability.

Background technique:

The surface self-propelled carrier is a kind of unmanned remote control monitoring equipment that navigates on water and has independent autonomy. It can complete marine environmental monitoring, sea rescue and other tasks in waters where large-scale monitoring work motherships such as coasts or coastal beaches cannot cruise. In the prior art, there are two methods for the course control of general self-propelled vehicles on the water surface, one is to use rudder control, and the other is to use two sets of longitudinal and transverse propellers, but these two structures are relatively complicated. The subversive resistance of the self-propelled carrier of these two structures is very weak, and the misfortune that causes shipwreck and capsize to be hit by wind and wave often all takes place. How to reduce the structural complexity of the carrier and improve the subversive resistance of the carrier is the purpose of the utility model.

Utility model content:

The utility model aims at the disadvantages of the above-mentioned prior art, and provides a self-propelled carrier with fixed double propellers with simple structure and good stability.

In order to achieve the above object, the utility model provides a self-propelled carrier with fixed double propellers, which mainly includes a hull and a propulsion device, and the propulsion device includes a fixed underwater electric propulsion device, a control device and a power supply device; Two sets of fixed underwater electric propellers are symmetrically arranged left and right at the stern of the hull. The control device controls the fixed underwater electric propellers. The fixed underwater electric propeller, control device and power supply device are installed at the bottom of the hull.

The fixed underwater electric propeller adopts a permanent magnet DC brushless motor for electric propulsion.

The power supply device is a storage battery.

Buoyancy components are installed on the upper part of the hull.

According to the utility model obtained by the above-mentioned technical solution, the installation position of the sculls is fixed in the power control, and the course can be changed by controlling the sculls to produce different thrusts, and the steering mechanism of the rudder or the paddles is omitted, and the structure is simple, The advantages of high reliability; the structural layout adopts a heavy hammer weight layout, and the propeller, battery and other heavy components are installed at the bottom of the carrier, while the main buoyancy components of the carrier are located on the upper part. The center of gravity of the whole self-propelled carrier is low, the center of buoyancy is high, and it has a large metacentric height, so it has good anti-overturning performance.

Description of drawings:

The utility model will be further described below in conjunction with the accompanying drawings and specific embodiments.

Fig. 1 is the back view of the utility model.

Fig. 2 is a side view of the utility model.

Fig. 3 is a top view of the utility model.

Detailed ways:

In order to make the technical means, creative features, goals and effects achieved by the utility model easy to understand, the utility model will be further elaborated below in conjunction with specific illustrations.

In order to make the self-propelled carrier simple in structure and good in subversive resistance, the utility model provides a self-propelled carrier with the structure shown in Fig. 1-3.

The self-propelled carrier has two sets of fixed underwater electric propellers 2 symmetrically arranged at the bottom of its stern, the control device connected to it and the power supply device for providing power are all arranged at the bottom of the hull 1, and the main buoyancy components of the whole carrier 3 is arranged on the top of hull 1. The power source of the self-propelled carrier is a high-energy battery, and a permanent magnet brushless DC motor suitable for electric propulsion of the self-propelled carrier is designed and developed. The sailing maneuvers control the course and speed. This makes the utility model have the following characteristics:

(1) The installation position of the two propellers is fixed, and the course is changed by controlling the two propellers to generate different thrusts, which saves the steering mechanism of the rudder or propeller, and has the advantages of simple structure and high reliability;

(2) The heavy hammer weight layout is adopted, and heavy components such as propellers and batteries are installed on the bottom of the carrier, while the main buoyancy components of the carrier are located on the upper part. The center of gravity of the entire self-propelled carrier is low, the center of buoyancy is high, and it has a large metacentric height. Therefore, the anti-overturning performance is good.

The basic principles and main features of the present utility model and the advantages of the present utility model have been shown and described above. Those skilled in the art should understand that the utility model is not limited by the above-mentioned embodiments. The above-mentioned embodiments and descriptions only illustrate the principle of the utility model. Without departing from the spirit and scope of the utility model, the utility model The new model also has various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection required by the utility model is defined by the appended claims and their equivalents.
