Description

Salinity sensor protection device for preventing marine organisms from being adsorbed by water flow

Technical Field

The invention belongs to the technical field of sensor equipment, and particularly relates to a salinity sensor protection device for preventing marine organisms from being adsorbed by water flow.

Background

In the process of marine observation and monitoring, parameters such as salinity, turbidity and dissolved oxygen of seawater can be rapidly and accurately acquired, the method has important significance for observing and knowing the sea, along with the development of sensor technology, salinity, turbidity, PH and dissolved oxygen of seawater are widely measured by a salinity sensor, in order to improve the accuracy of data acquisition, the salinity sensor is generally fixed on a ship body, the real-time detection of the parameters such as salinity and the like is carried out on the seawater in a large area range along with the movement of the ship body, two methods are commonly used for using the sensor, one is to fix the sensor on the ship through a rope or a connecting rod and the like, and then the sensor and a balancing weight are connected into a whole to fall into the sea, the replacement of the sensor is more convenient, but the condition that the rope or the connecting rod breaks when colliding with objects such as marine organisms, marine garbage and the like, and the recovery of the sensor is difficult can easily occur, in addition, when the ship body suddenly accelerates or jolts up and down under the influence of wind force, waves and other factors, the sensor is easy to shake on the sea surface, so that a large error occurs in a measurement result

The organisms such as fish, seaweed and shellfish are easy to be adsorbed on the sensor or the protective cover, so that the sensor can not normally contact with seawater, and the measurement result is influenced.

For example, patent No. CN 205580608U proposes a protection device for a temperature sensor probe for oceanographic investigation, which comprises a stainless steel tube, a rubber plug, a temperature sensor probe and a steel tube clamp, wherein the sensor probe is protected from collision by the steel tube, a water inlet is arranged at the bottom of the steel tube to facilitate the contact and measurement of the sensor with the incoming seawater, but when the seaweed and the seawater are in contact with each other

After marine organisms such as fish adsorb on the steel pipe, block up the inlet opening easily for the unable normal work of sensor, this problem has not been solved to the device.

For example, patent No. CN 208140141U proposes a biological adhesion prevention device for marine instruments, which includes a mounting seat, a transmission shaft, a swinging rudder, a shifting fork and a cleaning brush, wherein the swinging rudder is driven by wave energy, and the cleaning brush is driven by the transmission shaft and the shifting fork to swing on the surface of a sensor, thereby achieving the purpose of biological adhesion prevention, but there are some problems that the swinging rudder is in a streamline shape, when a ship moves, the swinging rudder is easily in a horizontal state under the influence of water flow, and the rotation is less, so that the cleaning brush is not easily driven by the shifting fork to swing, in addition, if the device is placed in seawater with a structure in which the cleaning brush is above and the sensor below, the connection length below the sensor is extended, thereby affecting the stability of the structure, if the device is placed in seawater with a structure in which the sensor is above and the cleaning brush below, there is no support structure below the cleaning brush, the stability is not enough, and the brush head is easy to separate from the sensor due to floating, and the cleaning effect is reduced.

In view of the above, the present invention provides a salinity sensor protection device that prevents marine organisms from adsorbing by using water flow, which is improved in view of the existing structure and defects, so as to achieve the purpose of higher practical value.

Furthermore, the right side of support sets up to the slope form corresponding with the hull, the support mounting is on the lateral wall of hull, for installing at the hull bottom, because the rivers change of hull both sides is great, is more difficult to have the marine organism to adsorb to go up, and the sensor contacts the quality of water situation more comprehensively moreover.

Furthermore, the protection tube is of a telescopic tube structure, so that the protection tube and the sensor body can be collected in the support to play a role in protection when the sensor is not used.

Further, the centre ring includes upper ring, linkage segment and lower ring, the centre ring rotates with the activity pipe through lower ring to be connected, and the centre ring is through upper ring and reset spring fixed connection, consequently, the activity pipe can reciprocate and rotate in the outside of protective tube through the centre ring.

Furthermore, the cylinders are distributed in the half edge area of the rotary table, the cylinders and the spiral ring form an intermittent transmission mechanism, the rotary table drives the movable pipe to rotate and move downwards through the cylinders and the spiral ring when rotating, and after the cylinders are separated from the spiral ring, the movable pipe moves upwards and resets under the pulling of the reset spring.

Compared with the prior art, the invention has the following beneficial effects:

1. when the hull moves ahead at sea, rivers drive the screw rotation, and rotatory screw drives the movable tube and moves at the outside of protection tube spiral from top to bottom, cleans the outside of protection tube through the scraper blade simultaneously, and the effectual marine organism of avoiding adsorbs on the protection tube, has ensured the normal work of sensor.

2. Through the outside installation protection tube at the sensor body to avoid objects such as marine life and marine waste to collide the sensor body and cause the sensor to damage, and the support mounting is on the lateral wall of hull, for the structure of installing the hull bottom, because the rivers change of hull both sides is great, more be difficult to have the marine life to adsorb to go, and the sensor that the rivers that toss about made contact the mobile sea water more in the same time, and then make detection effect more accurate.
