Description

Technical Field

[0001] This utility model relates to a sensing device, and more particularly to an integrated navigation and depth sensing device. Background Technology

[0002] To achieve precise control, underwater vehicles are typically equipped with sensors to detect heading, attitude, and depth data, thereby ensuring stable navigation. To detect these data, multiple sensors are required to collect corresponding environmental data. Existing sensors often use hardware to process and calculate the data from each sensor to obtain precise values, resulting in a large size for the hardware circuitry modules. Consequently, the housing housing the sensors and hardware circuitry modules also increases in size. This not only increases the overall size of the sensor but also reduces its reliability and lifespan due to the complexity of the hardware circuitry. Furthermore, the larger housing has relatively poor pressure resistance, reducing its applicability. Therefore, a smaller, more reliable integrated navigation and depth sensing device is needed to improve its applicability, reliability, and lifespan. Summary of the Invention

[0003] To solve the above-mentioned technical problems, this utility model provides a small-sized, highly reliable, and long-service-life integrated navigation and depth sensing device.

[0004] The present invention relates to an integrated depth sensing device, comprising a sensor and a housing with openings at both ends. An end cap is provided at one end of the housing and is fixedly connected to the housing. An installation groove is provided on the inner end face of the end cap. The sensor is disposed in the installation groove. A bracket is also provided inside the housing and is fixedly connected to the end cap. A mounting seat is provided on the bracket. A circuit board is provided inside the housing and is fixedly connected to the mounting seat.

[0005] A connector is provided at the opening at the other end of the housing. One end of the connector is fixed inside the opening of the housing, and the external cable passes through the connector and connects to the circuit board inside the housing.

[0006] The advantages of this integrated depth sensing device are that it has an end cap at one end of its housing, with a mounting groove for installing the sensor on the inner end face of the end cap, and a bracket for connecting the circuit board on the end cap. Because this integrated depth sensing device uses an optimized extended Kalman filter algorithm to process the raw sensing data of the sensor to output the optimal predicted value of the relevant data, it replaces the original scheme of using a large number of hardware processing modules to obtain accurate measurement values. Combined with the optimized structural design of the sensor, circuit board, etc., the overall structure of this integrated depth sensing device is more compact and small, thereby improving its stability, reliability and service life.

[0007] Furthermore, in the integrated depth sensing device of this utility model, the bracket is a ring-shaped bracket, which is fixed to the inner end face of the end cap by screws. A pressure plate is provided on the side of the ring-shaped bracket facing the sensor, with one end of the pressure plate fixed to the bracket and the other end in contact with the end face of the sensor.

[0008] The pressure plate is designed to press the sensor firmly into the mounting slot, thereby fixing the sensor in place and preventing it from moving relative to the mounting slot when the sensing device moves.

[0009] Furthermore, in this utility model's integrated depth sensing device, the screw is made of H62 brass.

[0010] The screw-connected ring bracket made of H62 brass reduces the risk of electromagnetic interference and also has strong corrosion resistance.

[0011] Furthermore, in the integrated depth sensing device of this utility model, the outer end of the end cap is provided with a connecting post, and the outer circumferential surface of the connecting post is provided with an external thread.

[0012] The connection post facilitates the installation of the sensor device on external equipment, such as a compass, by the operator, thus enabling the installation and fixation of the sensor device.

[0013] Furthermore, in the present invention, the integrated depth sensing device includes a housing comprising a main body and a connecting pipe integrally formed with the main body. The diameter of the connecting pipe is smaller than the diameter of the main body. An end cap is provided at the opening of the main body, and a connector is provided at the opening of the connecting pipe. The circumferential surface of the connecting pipe has several planes.

[0014] The connecting pipe and several planes on its circumference facilitate the operator in installing the end cap and connector onto the main body and the open end of the connecting pipe, respectively.

[0015] Furthermore, in this utility model's integrated depth sensing device, the circumferential surface of the end cap is provided with a sealing groove for installing a sealing ring.

[0016] The sealing groove allows for the installation of the sealing ring, thereby improving the sealing performance of the housing.

[0017] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the following describes the embodiments of this utility model in detail.

[0028] The advantages of this integrated depth sensing device are that it has an end cap at one end of its housing, with a mounting groove for installing the sensor on the inner end face of the end cap, and a bracket for connecting the circuit board on the end cap. Because this integrated depth sensing device uses an optimized extended Kalman filter algorithm to process the raw sensing data of the sensor to output the optimal predicted value of the relevant data, it replaces the original scheme of using a large number of hardware processing modules to obtain accurate measurement values. Combined with the optimized structural design of the sensor, circuit board, etc., the overall structure of this integrated depth sensing device is more compact and small, thereby improving its stability, reliability and service life.

[0029] The housing, serving as the main body of the sensing device, houses end caps, circuit boards, connectors, and other related components. It is a tubular structure open at both ends, made of pressure-resistant material such as titanium alloy. Its diameter is 15-25 mm, inner diameter is 15-20 mm, and length is 100-150 mm.

The circumferential surface of the connecting pipe has several flat surfaces to facilitate the operator's fixing of the connecting pipe and the main body, thereby facilitating the installation and fixing of the connector or end cap to the housing.

[0030] The end cap is used to mount the sensor and bracket. A mounting groove, which can be circular, is provided on its inner end face inside the housing. The sensor is placed within this mounting groove.

In this embodiment, there are two mounting bases, which are symmetrically arranged on the left and right sides of the hole in the annular bracket.

The circuit module on the circuit board communicates with the sensor through the sensor connector and uses an optimized Kalman filter algorithm to process the sensor data to obtain the optimal predicted value of the environmental data. The predicted value is then output to an external device via a cable.

[0037] The connector is used to connect the sensing device to external devices. It is installed at another opening of the housing and has a multi-core connector inside that connects to the circuit board. The multi-core connector is threaded to the housing.

A pressure plate is provided on the side of the ring-shaped bracket facing the sensor. One end of the pressure plate is fixed to the bracket, and the other end is in contact with the end face of the sensor.

[0042] Preferably, the outer end of the end cap is provided with a connecting post, and the outer circumferential surface of the connecting post is provided with external threads.

[0043] The connection post facilitates the installation of the sensor device on external equipment, such as a compass, by the operator, thus enabling the installation and fixation of the sensor device.

An end cap is provided at the opening of the main body, and a connector is provided at the opening of the connecting pipe. The circumferential surface of the connecting pipe has several planes.
