Detailed Description
The invention will now be further described with reference to the accompanying drawings in which:
referring to fig. 1 and 2, the problem to be solved by the invention is: the remote underwater vehicle can monitor the three-dimensional speed and the navigation depth in real time in the self-navigation process, and the stability of the remote underwater vehicle in the self-navigation process can be realized through the control of the control center. Based on this, the present invention adopts the doppler velocimeter to realize the basic functions described above.
The working process comprises the following steps: the Doppler velocimeter 6 measures the three-dimensional speed and the real-time water depth of the remote underwater vehicle in the self-navigation process by utilizing sound waves according to a Doppler principle, converts data into signals, transmits the signals into the control center 3 through a lead, and controls the course according to the obtained signals by the control center 3 so as to keep the stability in the self-navigation process.
In addition, the installation of the doppler velocimeter 6 is another problem to be solved by the present invention.
A mounting device for a remote underwater vehicle velocimeter for use at a navigation control section of a remote underwater vehicle, comprising: the Doppler velocimeter comprises a shell, a first sensor, a second sensor, a first signal processing module and a second signal processing module, wherein an opening is formed in the shell, and one end of the Doppler velocimeter is inversely installed in the shell through the opening;
the other end of the Doppler velocimeter is connected with the transition flange through a fastener;
the Doppler velocimeter is characterized by further comprising a control center, wherein the three-dimensional speed and the navigation depth measured by the Doppler velocimeter in the self-navigation process are monitored in real time, and signals are transmitted to the control center through a lead.
Typically, the diameter of the opening is 20-60mm greater than the maximum diameter of the velocimeter. In the installation process, firstly, the hole seat 7 is welded at the opening 8, the flat end face of the hole seat 7 faces the inside of the shell 2 to ensure that the other end face of the hole seat 7 is tangent to the outer surface of the shell 2, the flat end face of the hole seat 7 is matched with the transition flange 5 through the second screw 14, and the O-shaped sealing ring 12 is placed in the groove of the matching surface to enhance the sealing performance and stability.
Then, the Doppler velocity meter 6 is inversely arranged at an opening 8 of the navigation section 1 of the remote underwater vehicle, the bottom end of the Doppler velocity meter is connected with a transition flange 5 fixed inside the remote underwater vehicle through a third screw 16, the top end surface of the Doppler velocity meter is tangent to the outer surface of the shell 2, and a lead 11 is led out from a plug at the bottom end of the Doppler velocity meter 6 and is connected with the control center 3 for signal transmission.
Finally, the 45-degree opening end of the transition body 9 is aligned with the 45-degree opening end of the hole seat 7, and the transition body and the hole seat are connected through the first screw 13, so that on one hand, the transition body and the hole seat form a flow guide ring, the influence of flow noise of an installation part of the Doppler velocimeter can be reduced, and on the other hand, the inner wall of the transition body 9 fixed with the hole seat 7 is matched with the cylindrical part of the Doppler velocimeter 6, and the effect of further fixing the Doppler velocimeter 6 is achieved.
In the invention, the hole seat 7 and the transition body 9 are designed to have 45-degree opening inclined planes on one surface, so that the transmission of sound waves in the working process of the Doppler velocimeter 6 is not influenced.
Because the opening 8 is not sealed, the space 15 can enter seawater in the self-navigation process of the remote underwater vehicle, and the more the Doppler velocimeter 6 is in contact with the seawater in the working process, the better the effect is. In order to ensure the good working effect of the doppler velocity meter 6, the doppler velocity meter 6 in the working process needs to be in full contact with the seawater, that is, the space 15 is filled with the seawater. Based on this, the invention is provided with a hole 17 on the transition flange 5, one end of the pressure balance exhaust pipe 10 is sealed on the hole 17, and the other end is connected with the exhaust hole 4, which is used for exhausting the gas in the space 15, so as to ensure the full contact of the Doppler velocimeter 6 and the seawater in the working process.
