Problems solved by technology

At present, most of the underwater sensors are fixed in the shell of the sensor, exposing the sensing detection end face. Although the fixing method of this sensor is simple, it is difficult to realize the fixing of multiple or multiple sensors.
Chinese patent CN 103217591A discloses a marine environment electric field measuring device, which mainly includes a bracket, a spherical sealing body, a bracket, an electric field sensor and a watertight cable. The bracket is fixed with an inner hollow spherical sealing body, and the electric field sensor is fixedly installed in the spherical sealing body , the structure of this fixing method is relatively complicated, and only one sensor can be fixed in a spherical sealing body, which cannot meet the measurement requirements of simultaneous detection of multiple sensing signals or simultaneous detection of multiple sensors

Embodiment 1

[0032] Embodiment 1: is a basic embodiment of the present invention. Such as Figure 1-3 As shown, an underwater sensor fixing device includes a fixing ring 1 composed of a semi-circular arc-shaped fixing component 11 and a complementary semi-circular arc-shaped fixing component 12 . Both the semicircular arc-shaped fixing component 11 and the complementary semi-circular arc-shaped fixing component 12 are provided with an arc-shaped groove 13 for fixing and installing the sensor 2 . A bayonet 111 is provided at one end of the semi-arc-shaped fixing component. One end of the complementary semicircular arc-shaped fixing component 12 is provided with a block 121 matching the bayonet 111 . The bayonet socket 111 is fixedly connected to the block 121 through the axial bolt 14 . The other ends of the semicircular-arc-shaped fixing component 11 and the complementary semi-circular-arc-shaped fixing component 12 are provided with fastening terminals 15 , and are locked and fixed by ...

Embodiment 2

[0033] Embodiment 2: is a further embodiment of the present invention. Such as figure 2 , 4 As shown, on the basis of Example 1, the fixing ring is fixed on the watertight cable 4 (such as a watertight cable or an optical cable), and the semicircle-arc-shaped fixing component 11 and the complementary semi-circle-arc-shaped fixing component 12 are provided with diameters To the fastening bolts 17, the radial fastening bolts are symmetrically distributed about the center. Its function is to further enhance the firmness of fixing and prevent the fixing ring from sliding along the axial direction. In addition to watertight cables, the fixing ring 1 can also be fixed on pipelines such as oil pipes. Such as figure 1 As shown, the end of the radial fastening bolt 17 is further provided with a water injection groove 18 leading to the arc-shaped groove 13 for injecting water to remove air bubbles, thereby avoiding the pressure difference caused by air remaining in the sensor groov...

Embodiment 3

[0034] Embodiment 3: is a further embodiment of the present invention. On the basis of Example 1, such as Figure 5-7 As shown, the axial bolt is provided with a hollow inner cavity 141 , and the hollow inner cavity 141 can be used as a cable channel, and can also fixedly support the fixed seat 5 . The fixed seat 5 and the hollow inner cavity 141 are connected and fixed by epoxy resin bonding. The fixed seat 5 is equipped with a watertight connector 6, and the watertight connector 6 can be single-channel or multi-channel. The fixed seat can also install accessories such as wireless signal transmitters and locators. The underwater sensor is connected with the watertight connector through the wire, and the watertight connector is further connected with the watertight cable or the optical cable. When the hollow inner cavity is provided with a watertight connector and sealed by an adhesive such as epoxy resin, it is an equivalent embodiment.

Abstract

The invention discloses an underwater sensor fixing device. The underwater sensor fixing device comprises a fixing ring composed of a semi-circular-arc-shaped fixing assembly and a complementary semi-circular-arc-shaped fixing assembly. The semi-circular arc fixing assembly and the complementary semi-circular arc fixing assembly are provided with arc grooves used for fixedly installing sensors. Abayonet is formed in one end of the semi-arc-shaped fixing assembly; a clamping block matched with the bayonet is arranged at one end of the complementary semi-arc-shaped fixing assembly. The bayonetis fixedly connected with the clamping block through an axial bolt; and fastening terminals are arranged at the other ends of the semi-circular arc fixing assembly and the complementary semi-circulararc fixing assembly and are locked and fixed through fastening bolts. The underwater sensor fixing device is simple in structure, convenient to process, firm in fixation, capable of fixing multiple ormultiple sensors, and particularly suitable for fixing underwater electric field sensors.

Description

technical field [0001] The invention relates to an underwater sensor fixing device, which is especially suitable for fixing marine electric field sensors. Background technique [0002] With the development of marine science and technology and the increase of energy demand, marine physical detection technology has achieved rapid development. Multi-dimensional collection of ocean physical and chemical information such as temperature, pressure, electric field, magnetic field, etc. will help deepen our understanding of the ocean. The rapid development of big data, cloud computing, and wireless signal transmission technologies has created convenient conditions for comprehensive monitoring of ocean physical and chemical information. The acquisition of ocean physicochemical information relies on underwater sensors. Due to the particularity of the marine environment, the fixing device of the sensor is very important, so it is urgent to develop an underwater sensor that is easy to ...
