Description

Technical field:

[0001] The invention belongs to the technical field of underwater equipment, and in particular relates to an automatic replacement system for underwater sensors. Background technology:

[0002] Underwater sensors are widely used in the fields of ocean, aquaculture, water supply, sewage, etc., and can provide users with information such as water quality parameters, temperature, and pressure. Underwater sensors in the prior art require regular maintenance to maintain their measurement accuracy when used underwater. At the same time, biological attachment is serious in the water environment, which seriously affects the performance of the sensor, and sensor maintenance and biological attachment cleaning require a lot of manpower, material resources and financial resources, especially when sensors are installed on a large scale. Moreover, for sensors deployed in the open sea, maintenance or cleaning will be affected by bad weather. Current research on underwater sensors mainly extends their service life by adding cleaning equipment. The present invention provides an underwater sensor automatic replacement system, which can carry multiple underwater sensors and can automatically update and replace the sensors underwater when the sensor performance deteriorates, without the need for manual intervention, eliminating the need for regular maintenance of the sensors, and overcoming the impact of biological attachment. Summary of the invention:

[0003] The purpose of the present invention is to provide an automatic replacement system for underwater sensors, which solves the problem that existing underwater sensors require regular maintenance and are easily affected by biological adhesion.

[0004] The present invention relates to an automatic underwater sensor replacement system, comprising a shell, a recovery unit, a motor, a motor push rod, a sensor, a sensor cavity and a control mainboard. The control mainboard, the motor, the motor push rod and the sensor cavity are fixed in the shell, and the front end opening of the sensor cavity is sealed at the connection with the rear end of the shell. The recovery unit is fixedly connected to one end of the shell close to the sensor cavity and is communicated with the front end opening of the sensor cavity. The sensor cavity is divided into a working sensor placement area at the front end and a spare sensor placement area at the rear end. The working sensor placement area can only accommodate one sensor as a working sensor, and at least one sensor is placed in the spare sensor placement area as a spare sensor. All sensors in the sensor cavity are placed in sequence end to end, and the outer periphery of the sensor is sealed with the inner wall of the sensor cavity. The motor is connected to the motor push rod, and the free end of the motor push rod rests on the spare sensor at the rear end. The working sensor and the motor are respectively connected to the control mainboard, and their operation is controlled by the control mainboard.

[0005] Specifically, the sensor is pressed against the inner wall of the sensor cavity in the circumferential direction through a sealing ring. Other sealing methods can also be used for connection.

[0006] Specifically, the sensor includes a sensor base, a sensor core, an alignment protrusion, an alignment groove and a signal transmission conductive pin. The sensor core is fixed on the sensor base. The alignment groove and alignment protrusion are fixedly set at the front and rear ends of the sensor base respectively. The alignment protrusion of one sensor is inserted into the alignment groove of the adjacent sensor behind it. A number of signal transmission conductive pins are evenly arranged along the circumferential direction on the bottom of the sensor base. A number of signal receiving conductive springs are evenly arranged along the circumferential direction on the inner wall of the sensor cavity in the working sensor placement area. The signal receiving conductive springs correspond to the signal transmission conductive pins on the working sensor. The signal transmission conductive pins are connected to the sensor core. The signal receiving conductive springs are connected to the control main board outside the sensor cavity to send the sensor detection signal to the control main board.

[0007] Specifically, a signal transmission opening is provided on the sensor cavity corresponding to the signal receiving conductive spring piece, and the signal receiving conductive spring piece is connected to the control mainboard through the signal transmission opening.

[0008] Specifically, the inner diameter of the sensor cavity can just accommodate the outer diameter of the sensor.

[0009] Specifically, the number of the signal transmission conductive pins may be more than two, such as two, three, or four. Correspondingly, the number of the signal receiving conductive springs is the same as the number of the signal transmission conductive pins.

[0010] Specifically, the recovery unit is a recovery net or a recovery frame, which is connected to the front end opening of the sensor cavity, or connected to the front end of the shell to achieve communication with the sensor cavity.

[0011] Specifically, when the front end surface of the sensor is flush with the front end opening of the sensor cavity, the signal transmission conductive pin on the working sensor is aligned with the signal receiving conductive spring.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] (1) When the sensor performance degrades or reaches the end of its service life, it will be automatically replaced, eliminating the need for regular sensor maintenance and ensuring sensor accuracy;

[0014] (2) The sensor alignment unit ensures that all sensors in the sensor cavity are arranged regularly, thereby ensuring that the signal transmission conductive pins on the sensors can be accurately aligned with the signal receiving conductive springs on the inner wall of the sensor cavity, and ensuring that the sensors can automatically start after reaching the working sensor placement area;

[0015] (3) Design the sensor cavity according to the size and number of sensors to be carried. Description of the drawings:

[0022] The present invention will be further described below through examples with reference to the accompanying drawings.

[0023] Example 1

[0024] like Figure 1 and 2 As shown, the present embodiment involves an underwater sensor automatic replacement system, comprising a housing 1, a recovery unit 2, a motor 3, a motor push rod 4, a sensor 5, a sensor cavity 6 and a control mainboard (not shown in the figure). The control mainboard, the motor 3, the motor push rod 4 and the sensor cavity 6 are fixed in the housing 1. The front end opening of the sensor cavity 6 is sealed at the connection with the rear end of the housing 1. The recovery unit 2 is fixedly connected to one end of the housing 1 near the sensor cavity 6 and is connected to the front end opening of the sensor cavity 6. The sensor cavity 6 is divided into a working sensor placement area at the front end and a spare sensor placement area at the rear end. The working sensor placement area can only accommodate one sensor as a working sensor, and at least one sensor is placed in the spare sensor placement area as a spare sensor. All sensors 5 in the sensor cavity 6 are placed in sequence end to end, and the sensor 5 is abutted against the inner wall of the sensor cavity 6 in the circumferential direction by a sealing ring 7 to prevent water from entering the housing 1 from the sensor cavity. The number of the sealing rings is at least two. The motor 3 is connected to the motor push rod 4. The free end of the motor push rod 4 abuts against the spare sensor at the rear end. The working sensor and the motor are respectively connected to the control mainboard, and their operation is controlled by the control mainboard. When the working sensor detects a sudden change in the sensor signal, or the working sensor reaches the end of its service life, the control motor 3 drives the motor push rod 4 to move, pushing the sensor forward one sensor position, and the working sensor falls into the recovery unit 2. The spare sensor adjacent to the working sensor is connected to the control main board as a new working sensor.

[0025] Specifically, the sensor 5 includes a sensor base 501, a sensor core 502, an alignment protrusion 503, an alignment groove 504 and a signal transmission conductive pin 505. The sensor core 502 is fixed on the sensor base 501, and the alignment groove 504 and the alignment protrusion 503 are fixedly set at the front and rear ends of the sensor base 501 respectively. The alignment protrusion 503 of one sensor is inserted into the alignment groove 504 of the adjacent sensor behind to realize the connection between the two. A number of signal transmission conductive pins 505 are evenly arranged along the circumferential direction at the bottom of the sensor base 501, and a number of signal receiving conductive springs are evenly arranged along the circumferential direction on the inner wall of the sensor cavity 6 in the working sensor placement area. The signal receiving conductive springs correspond to the signal transmission conductive pins on the working sensor. The signal transmission conductive pins 505 are connected to the sensor core 502. The signal receiving conductive springs are connected to the control main board outside the sensor cavity 6 through the signal transmission opening 8 opened on the sensor cavity 6 to send the sensor detection signal to the control main board. Alignment protrusions 503 and grooves 504 form a sensor alignment unit. This unit ensures that all sensors within the sensor cavity are arranged in a regular pattern, ensuring that the signal transmission conductive pins 505 of the replaced sensor are accurately aligned with the signal receiving conductive springs on the inner wall of the sensor cavity. When the signal transmission conductive pins 505 are accurately aligned with the signal receiving conductive springs, the working sensor automatically activates.

[0026] Specifically, the inner diameter of the sensor cavity can just accommodate the outer diameter of the sensor 5 .

[0027] Preferably, four signal transmission conductive pins are evenly arranged along the circumferential direction on the bottom of the sensor base 501, and correspondingly, four signal receiving conductive springs are evenly arranged along the circumferential direction on the inner wall of the sensor cavity in the working sensor placement area.

[0028] Specifically, the recovery unit 2 can be a recovery net or a recovery frame, which can be connected to the front end opening of the sensor cavity 6 to directly communicate with the sensor cavity 6, or it can be connected to the front end of the shell 1 to achieve communication with the sensor cavity 6.

[0029] For ease of installation, when the front face of the sensor is flush with the front opening of the sensor cavity 6 , the signal transmission conductive pins on the working sensor are aligned with the signal receiving conductive springs.

[0030] When the working sensor signal changes suddenly, or the working sensor reaches the end of its service life, the control mainboard controls the motor to work. Driven by the motor 3, the free end of the motor push rod 4 extends into the sensor cavity 6 to push all sensors forward by one sensor position. The working sensor enters the recovery unit 2, and the replacement sensor adjacent to the working sensor is moved to the working sensor placement area as a working sensor. The signal transmission conductive pin on the sensor is aligned with the signal receiving conductive spring. The front end face of the sensor is flush with the front end opening of the sensor cavity 6. The signal transmission conductive pin is connected to the signal receiving conductive spring. The sensor can be used as a working sensor. The sensor probe at the front end of the sensor contacts the water and starts working.
