Description

Technical Field

[0001] This utility model relates to the field of unmanned surface vessel (USV) technology, specifically a robust protection device for sensors on a marine USV. Background Technology

[0002] During the operation of unmanned surface vessels (USVs) at sea, the sensors installed on the bottom of the USV play a role in transmitting and receiving signals, exploring depth and avoiding obstacles. These sensors are very important on the USV. When a ship approaches or collides with the USV, they will provide early warnings and location information, which can remind the operator to avoid obstacles or return to port in time. However, sometimes when the USV encounters sudden situations such as fish attacks or collisions with reefs, it is easy to cause serious damage to the surrounding sensors. Since the sensors are manufactured with precision and are expensive, protecting the sensors is particularly important. For example, application number CN202221326406.5 discloses a robust protection device for a sensor of an unmanned surface vessel (USV), comprising a main body, the main body including a mounting plate, a connecting rod fixedly connected to the bottom of the mounting plate, a protective shell fixedly mounted on both sides of the bottom of the connecting rod by a reinforcing plate, a guide plate mounted on the front of the protective shell, and a mounting frame fixedly mounted inside the protective shell. The bottom of the mounting frame and the four sides adjacent to the bottom are equipped with buffer structures to enhance the protection effect, and a shock-absorbing structure to effectively ensure stability is installed at the bottom of the mounting frame. A mounting base is fixedly mounted on the top of the shock-absorbing structure, and the sensor body is mounted on the top of the mounting base. By setting the buffer structure, the device can effectively improve the protection strength of the device, thereby better protecting the sensor.

[0003] However, most existing stabilization and protection devices for unmanned surface vessels (USVs) sensors simply wrap around the sensor for protection, failing to provide effective pressure relief in the event of an impact. Furthermore, the sensor's front end often accumulates a large amount of impurities, affecting its normal sensing operation and requiring frequent cleaning by personnel, which is very troublesome. Therefore, this application proposes a stabilization and protection device for USV sensors to solve this problem.

[0004] No effective solutions have yet been proposed to address the problems in the relevant technologies. Utility Model Content

[0005] The purpose of this invention is to provide a robust protection device for sensors of unmanned surface vessels at sea, so as to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model provides a stabilizing protection device for a sensor of an unmanned surface vessel (USV), including a protective frame, a pressure relief mechanism, and a cleaning mechanism. The sensor body is located inside the protective frame. The pressure relief mechanism includes a pressure relief frame, a piston groove, a pressure relief hole, a spring, a piston pad, and a sealing gasket installed at the rear end of the protective frame. The protective frame is sleeved with the piston groove. The cleaning mechanism includes a cleaning frame, a cleaning brush, and a motor installed at the front end of the protective frame. The motor is used to drive the cleaning frame to swing.

[0007] Preferably, the front end of the protective frame is provided with a protective head, the protective head is welded to the protective frame, and the sensor body is bolted to the protective frame.

[0012] Compared with the prior art, the present invention has the following beneficial effects: 0. This utility model is a stabilizing and protective device for a sensor of an unmanned surface vessel (USV). It is equipped with a protective frame and a pressure relief mechanism. The protective frame is sleeved on one end of the pressure relief mechanism. When subjected to impact or compression, the protective frame retracts along the pressure relief frame into the piston groove, compressing the sealing gasket and piston. This allows the air in the piston groove to be slowly discharged through the pressure relief hole, facilitating the slow and anti-collision pressure relief effect. After compression, the spring pushes the protective frame, causing the protective head to extend out of the piston groove. This effectively prevents the sensor from being damaged due to excessive pressure, extends the sensor's service life, and improves its reliability in complex marine environments.

[0013] 1. This utility model is a stabilizing and protective device for a sensor of an unmanned surface vessel at sea. A cleaning mechanism is set at the front end of the protective frame. The cleaning frame is driven by a motor on the cleaning mechanism to rotate along the protective head, which can remove the substances attached to the protective head, prevent debris from affecting the normal operation of the sensor body, and ensure that the detection accuracy and sensitivity of the sensor are not affected by impurities and marine organisms.

[0017] The utility model will now be further described with reference to the accompanying drawings and specific embodiments: Please see Figure 1-4 According to an embodiment of the present invention, a stabilizing and protective device for a sensor of an unmanned surface vessel (USV) includes a protective frame 1, with a sensor body 101 inside the protective frame 1. A pressure relief mechanism 2 includes a pressure relief frame 201, a piston groove 202, a pressure relief hole 203, a spring 204, a piston pad 205, and a sealing pad 206 installed at the rear end of the protective frame 1. The protective frame 1 is sleeved with the piston groove 202. A cleaning mechanism 3 includes a cleaning frame 301, a cleaning brush 302, and a motor 303 installed at the front end of the protective frame 1. The motor 303 is used to drive the cleaning frame 301 to swing. The present invention provides pressure relief protection for the sensor body 101 inside the protective frame 1 through the pressure relief mechanism 2, which can effectively prevent damage caused by collision. The cleaning mechanism cleans the surface of the protective head 102 at the front end of the sensor body 101, which can effectively prevent impurities from affecting the sensor's sensing effect. It is suitable for use on unmanned surface vessels.

[0018] According to the above-mentioned solution of this utility model, the front end of the protective frame 1 is provided with a protective head 102, the protective head 102 is welded to the protective frame 1, the sensor body 101 is bolted to the protective frame 1, the sensor body 101 is connected to the data processing system inside the unmanned surface vessel through a cable, and the protective head 102 is made of a non-metallic cover to facilitate the normal transmission of sensor signals.

[0019] According to the above-described scheme of this utility model, the piston groove 202 is located at one end of the pressure relief frame 201, the pressure relief hole 203 is located on one side of the piston groove 202, the piston pad 205 is sleeved in the piston groove 202, the sealing gasket 206 is located on one side of the piston pad 205, the sealing gasket 206 is bolted to the protective frame 1, the piston pad 205 and the sealing gasket 206 are heat-fused together, the spring 204 is pressed on one side of the sealing gasket 206, and the other end of the spring 204 is pressed together with the pressure relief frame 201, which facilitates the pressure relief protection operation.

[0020] According to the above-described scheme of this utility model, the outer side of the protective frame 1 is provided with a storage groove 103, the cleaning frame 301 is located inside the storage groove 103, the cleaning brush 302 is located inside the cleaning frame 301, the cleaning frame 301 is connected to the protective frame 1 by a bearing, the cleaning brush 302 is bolted to the cleaning frame 301, the cleaning brush 302 is in contact with the protective head 102, the motor 303 shaft is connected to one end of the cleaning frame 301, the motor 303 is bolted to the protective frame 1, and the motor 303 is composed of a micro geared motor, which facilitates driving the cleaning frame 301 to rotate and clean the protective head.

[0021] In practical use, when the unmanned surface vessel is in operation, if the internal pressure of the protective frame 1 increases due to changes in the external environment such as water flow or collisions, the pressure acts on the piston pad 205, pushing the piston pad 205 to move along the piston groove 202. This compresses the air in the piston groove 202 and slowly discharges it through the pressure relief hole 203, facilitating the slow and anti-collision pressure relief effect. After the compression is completed, the spring 204 pushes the protective frame 1, causing the protective head 102 to extend out of the piston groove 202. This effectively prevents the sensor from being damaged due to excessive pressure, extends the service life of the sensor, and improves its reliability in complex marine environments.

[0022] After the motor 303 starts, its shaft drives the cleaning frame 301 to swing around the bearing connection point with the protective frame 1. Since the cleaning brush 302 is fixedly connected to the cleaning frame 301 and fits against the protective head, the cleaning brush 302 cleans the surface of the protective head as the cleaning frame 301 swings, removing impurities and marine organisms attached to it, ensuring the normal operation of the sensor.
