[0022] like Figures 1 to 6 As shown, an underwater sensor protection device includes a base 1 and an upper cover plate 5. The base 1 is provided with a fixing hole 101 welded on it, and a reinforcing rib 6 is welded inside the base 1.

[0023] The base 1 is installed on the water-facing side of the bridge pier and abutment through the fixing hole 101.

[0024] The front end of the base 1 is fixedly provided with a first sensor 7, and the inside of the base 1 is provided with a second sensor 8. The first sensor 7 adopts a pulsating water pressure sensor; and the second sensor 8 adopts an acceleration sensor.

[0025] The upper end of the base 1 is fixedly provided with an upper cover plate 5, and the front end face of the base 1 is provided with an opening and closing mechanism 2. The opening and closing mechanism 2 is hinged at the front end of the base 1. An electric motor 4 is arranged in the base 1, and the electric motor 4 drives the opening and closing mechanism 2 through a connecting rod mechanism 3. The connecting rod mechanism 3 is hingedly matched with lugs 301 on the rear end face of the opening and closing mechanism 2.

[0026] The base 1 is provided with a control box 9, and the control box 9 is electrically connected with the first sensor 7, the second sensor 8 and the electric motor 4.

[0027] The pulsating water pressure sensor comprises a pulsating water pressure sensor interface, an anti-loosening nut and a spring washer. As a solid and reliable device, the pulsating water pressure sensor directly faces water flow impact, is provided with the anti-loosening nut and the spring washer, and can be effectively fixed on the pulsating water pressure sensor support.

[0028] The acceleration sensor comprises an acceleration sensor interface, a mounting bottom plate, an anti-loosening screw and an expansion screw. The acceleration sensor is assembled together through the anti-loosening screw and the mounting bottom plate, and after assembly, the assembled mounting bottom plate is fixed on the bearing platform through the expansion screw.

[0029] The pulsating water pressure sensor interface and the acceleration sensor interface provide a direct communication connection mode for an external acquisition device, so that the pulsating water pressure and the acceleration change of the bearing platform can be learned in real time.

[0030] The control box 9 is arranged in the hollow support of the pulsating water pressure sensor, the control box 9 can directly collect pulsating water pressure sensor data, the hollow support of the pulsating water pressure sensor is filled with silica gel, and the control line of the automatic control system is directly connected with the electric motor 4.

[0031] The pulsating water pressure sensor and the electric motor 4 are cooperated under the automatic control system of the control box 9, the automatic control system reads the pressure change of the pulsating water pressure sensor in real time, the pressure value suddenly changes when the impurities impact, the automatic control system starts the electric motor 4 to rotate. The connecting rod mechanism is composed of three connecting rods, the connecting rod end directly connected with the electric motor 4 is firmly welded and constrained by two lugs 301, the constraint angle is 60°, the electric motor 4 rotates the opening and closing mechanism 2 in clockwise direction to perform closing action, and rotates the opening and closing mechanism 2 in counterclockwise direction to perform opening action.

[0032] In the connecting rod mechanism 3, the connecting rods are connected with each other and with the opening and closing mechanism by hinges, so that the connecting rods can move along a certain trajectory.

[0035] In order to improve the overall structural stiffness and not to deform when impacted, the angle steel frame of the base 1 is 3mm thick, and the internal cross brace reinforcing rib 6 is additionally provided, which greatly improves the overall anti-impact ability of the structure.

[0036] When there is no debris impact, the protection device is in a closed state, forming a protective barrier for the sensor. When there is debris rushing towards the water surface with the water flow, the automatic control system will start the motor 4 to rotate according to the signal from the sensor such as a pressure sensor, and drive the opening and closing mechanism 2 through the connecting rod mechanism 3 to open a certain angle, so that the debris passes under the action of the water flow, avoiding the accumulation of debris in front of the protection device to cause continuous pressure on the sensor. At the same time, at the appropriate time such as after the debris passes or accumulates to a certain extent, the automatic control system starts the motor 4 again to close the opening and closing mechanism 2.
