[0002] Safety hazards or accidents in water conservancy projects can cause irreversible damage to the lives and property of surrounding residents. Therefore, quality inspection and control of underwater concrete in water conservancy projects are essential to ensure the overall safety and reliability of these projects. Currently, the internal quality of concrete is mainly detected using accelerometers, but these sensors are not waterproof or pressure-resistant in complex aquatic environments, limiting the detection of underwater concrete quality primarily to the detection of surface defects.

The upper protective shell and the lower protective shell are detachably connected. The upper protective shell and the lower protective shell enclose a sealed space in which a sensor is disposed. The detection end of the sensor is provided with a signal rod. The end of the signal rod away from the sensor passes through a reserved hole on the lower protective shell, and the signal rod is sealed to the reserved hole on the lower protective shell.

[0005] Preferably, the upper protective shell and the lower protective shell are connected by a threaded structure.

[0006] Preferably, the sensor and the signal rod are connected by a threaded structure.

[0017] To make the technical problems, technical solutions and beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and embodiments.

[0018] like Figure 1 and 2 As shown in the figure, this embodiment discloses a sensor protection device for detecting the quality of underwater concrete, including an upper protective shell 1 and a lower protective shell 2. The upper protective shell 1 and the lower protective shell 2 are detachably connected. Both the upper protective shell 1 and the lower protective shell 2 are cylindrical and arranged coaxially. A sensor 3 is installed in the sealed space formed by the upper protective shell 1 and the lower protective shell 2. A signal rod 4 is provided at the detection end of the sensor 3. The axis of the signal rod 4 coincides with the axis of the upper protective shell 1. The end of the signal rod 4 away from the sensor 3 passes through a reserved hole on the lower protective shell 2, and the signal rod 4 is sealed to the reserved hole on the lower protective shell 2.

[0019] After the entire device is assembled, the length of the signal rod 4 protrudes a certain distance (generally no more than 5cm) relative to the lower protective shell 2. The sensor 3 can receive external vibration signals through the signal rod 4, effectively preventing direct contact between the sensor 3 and water, thus achieving waterproof and pressure-resistant properties in aquatic environments. The sensor 3 is generally an acceleration sensor.

[0020] In this embodiment, the upper protective shell 1 is provided with an external thread at its connecting end, and the lower protective shell 2 is provided with an internal thread at its connecting end. The upper protective shell 1 and the lower protective shell 2 are connected by a threaded structure, and a sealing ring can be installed or glue can be applied to the connection between the two.

[0021] In this embodiment, the detection end of the sensor 3 is provided with a threaded hole, and the signal rod 4 is connected to the threaded hole of the detection end of the sensor 3 through a threaded structure.

[0022] In this embodiment, a sealing ring 5 is provided on the outer wall of the signal rod 4, and the sealing ring 5 is interference-fitted with the reserved hole on the lower protective shell 2.

[0023] In this embodiment, a cable guide sleeve 6 is provided on the side wall of the upper protective shell 1. The signal line connected to the sensor 3 exits through the cable guide sleeve 6. The cable guide sleeve 6 is filled with sealant for waterproof sealing of the auxiliary signal line.

[0024] In this embodiment, the cable guide sleeve 6 is arranged perpendicularly to the axis of the upper sheath 1. The outer wall of the upper sheath 1 is provided with a threaded hole for mounting the cable guide sleeve 6. The cable guide sleeve 6 is connected to the upper sheath 1 through a threaded structure. The connection position between the cable guide sleeve 6 and the upper sheath 1 is sealed with adhesive.

[0025] In this embodiment, the upper protective shell 1 is provided with an extension rod 7 on the side opposite to the lower protective shell 2. The extension rod 7 is arranged coaxially with the upper protective shell 1 and can be connected to an extension rod.

[0026] The embodiments described above are merely preferred embodiments of the present utility model and are not intended to limit the scope of the present utility model. Various modifications and improvements made to the technical solutions of the present utility model by those skilled in the art without departing from the spirit of the present utility model should fall within the protection scope defined by the claims of the present utility model.
