Description

Technical Field

[0001] The utility model relates to the technical field of sonar detection equipment, in particular to a seabed sonar detection device. Background Art

[0002] With the implementation of ocean development, people have turned their attention to the ocean, especially in the field of seabed exploration, which is an essential step in the development of marine resources. However, the current seabed detection devices are basically towed by cables, and then the detection devices are placed in the sea and allowed to sink naturally to the set depth for detection.

[0003] When it comes to deeper waters, the sonar device relies solely on its own gravity to carry out sinking work, which results in a slower sinking speed. The process of the device reaching the target depth is relatively long, which increases the detection time and affects the detection efficiency. Utility Model Content

[0004] The purpose of the utility model is to provide a seabed sonar detection device to solve the problems raised in the above background technology.

[0006] The effects achieved by the above components are: two hemispherical shells can be assembled into a sphere for placing the sonar detection component to protect the sonar detection component. When the device is put into the seawater, the solenoid valve opens, and seawater enters the side cavity from the liquid guide tube. The air in the side cavity can be pressed into the inner cavity when the pipe in the drainage component is open until the side cavity is filled with seawater, and the pipe and solenoid valve of the drainage component are closed to relieve pressure and exhaust the device as a whole, thereby reducing the buoyancy of the device as a whole. When the device falls into deeper sea areas, the speed is faster. After the sonar detection component completes the detection, the drainage component is used to blow air into the side cavity when the solenoid valve is opened to discharge seawater from the liquid guide tube to the outside, thereby increasing the overall buoyancy of the device, and cooperating with the connecting component to pull the device upward, so that it is convenient and quick to retrieve it for the next launch.

[0007] Preferably, the drainage assembly comprises an air pump mounted on the inner wall of the inner cavity, an air outlet end of the air pump is fixed with an air guide tube extending to the inner wall of the side cavity, and the air guide tube is provided with a valve.

[0008] The effect achieved by the above components is: the air pump can cooperate with the air guide pipe to introduce the air in the inner cavity into the side cavity when the valve is opened, and the air will be used to discharge the seawater in the side cavity to achieve the purpose of increasing buoyancy.

[0009] Preferably, a liquid level sensor is installed at the top of the inner cavity, and a signal output end of the liquid level sensor is connected to a control module.

[0010] The effect achieved by the above components is: the liquid level sensor can be used to detect the seawater level in the side cavity in a timely manner. When the seawater level is higher than the set height, the control module is used to close the valve and the solenoid valve in a timely manner to prevent excessive seawater from flowing back into the inner cavity from the drainage component.

[0011] Preferably, the connection assembly includes a sleeve fixed at the center position of the top of the cover plate, and a wire hole is opened on the outer side wall of the bottom end of the sleeve, and a cable is inserted into the top end of the sleeve and led out from the wire hole.

[0012] The effects achieved by the above components are: the cable can be bolted and fixed by the sleeve in cooperation with the wire hole, and the cable can be retracted and released by connecting to an external reeling mechanism.

[0013] Preferably, a wire ring is fixed on one side of the sleeve, and a steel wire connected to the cover plate is passed through the wire ring.

[0014] The effect achieved by the above components is: the traction strength of the device can be increased through the steel wire, so as to avoid the loss of the device due to the collision and wear of the cable with sea rocks.

[0015] Preferably, the base is fixed with a placing ring, and the bottom end of the sonar detection component is placed in the placing ring.

[0016] The effect achieved by the above components is: the bottom end of the sonar detection component can be limited by the placement ring to improve the placement stability.

[0017] The utility model provides a submarine sonar detection device through improvement, which has the following improvements and advantages compared with the prior art:

When the device falls into a deeper sea area, the speed is faster. After the sonar detection component completes the detection, the liquid discharge component is used to blow air into the side cavity when the solenoid valve is opened, and the seawater is discharged from the liquid guiding tube to the outside, thereby increasing the overall buoyancy of the device. The device is pulled upward in cooperation with the connecting component, so that it is convenient and quick to be retrieved for the next launch. BRIEF DESCRIPTION OF THE DRAWINGS
