[0002] In modern fields such as water conservancy, ocean, and industry, accurately measuring water speed is an important task. Traditional methods of arranging water speed meter probes may have problems such as inconvenient operation, low efficiency, and difficulty in ensuring accuracy. For example, manually operating the probe to enter and exit the cabin is not only time-consuming and laborious, but also difficult to achieve precise control, and is easily affected by human factors, resulting in large errors in measurement results.

[0003] With the continuous development of technology and the increasing requirements for measurement accuracy and efficiency, electric control technology has gradually been introduced into the operation of the water speed meter probe entering and exiting the cabin. Electric control can achieve more precise and stable movements, improve the degree of automation of operations, reduce human interference, thereby improving the accuracy and reliability of measurement data.

[0019] The present utility model will be further described below in conjunction with the drawings and embodiments.

[0020] Embodiment 1: A device for electrically controlling the entry and exit of a water velocity meter probe into and out of a cabin, as Figures 1-7 shown, the device is composed of a control and feedback system, a driving mechanism, a connection and fixing guiding mechanism, a water velocity meter probe, and a protection and sealing mechanism from top to bottom.

[0021] Furthermore, the control and feedback system is used to control the actions of the driving mechanism to achieve precise probe entry and exit operations, and detect the position and action status of the probe through position sensors for real-time adjustment and control. The control and feedback system is composed of a control cabin housing, a control board, a motor drive board, an electrical connector, a probe connection cable, an in-cabin position sensor, and an out-of-cabin position sensor. The control cabin housing serves as the installation base of the control and feedback system. The control board and the motor drive board are fixedly stacked on the top of the control cabin housing by screws. The in-cabin position sensor, the out-of-cabin position sensor, and the probe connection cable are all connected to the control board. The in-cabin position sensor is arranged at the start of the stroke, the out-of-cabin position sensor is arranged at the end of the stroke, and the electrical connector is responsible for the power input of the control and feedback system and communication with the outside.

[0022] Furthermore, the drive mechanism is the power source for the probe to enter and exit the cabin. The motor drives the screw rod to convert the motor's rotational motion into linear motion. The drive mechanism consists of a motor, a screw rod and a screw nut. The screw rod is the motor output shaft. The rotation of the motor directly drives the screw nut to perform linear motion.

[0023] Furthermore, the connecting and fixing guide mechanism is responsible for firmly fixing the water speed meter probe and realizing reliable connection with the driving structure to ensure that the driving force can be effectively transmitted to the water speed meter probe, so that it can move along a predetermined linear trajectory. The connecting and fixing guide mechanism is composed of a cabin entry buffer block, a motor mounting plate, a guide housing, a cross slider, a cabin exit buffer block, a rolling bearing, a linear bearing, a bearing mounting plate, a guide connecting rod, and a probe connecting and fixing plate from top to bottom. The motor mounting plate and the bearing mounting plate are respectively mounted at both ends of the guide housing, and the three form a hollow cavity. The motor is mounted on the motor mounting plate and an cabin entry buffer block is installed at the beginning of the stroke. The screw passes through a cross slider equipped with a screw nut, and the end of the screw is inserted into the rolling bearing on the bearing mounting plate so that it can rotate freely. The cross slider is connected to the probe through four guide connecting rods. The head is connected to the fixed plate, and the lead screw nut rotates with the motor to drive the cross slider to make a linear motion inside the connecting and fixing guide mechanism. The probe fixing plate makes a linear motion outside the connecting and fixing guide mechanism with the cross slider. The four guide links and the bearing mounting plate are matched through linear bearings. The linear bearings can reduce the friction resistance between the guide links while ensuring the precise movement of the guide links in the linear direction, preventing the guide links from deflecting or shaking during the movement, and playing a guiding role. The cabin entry buffer block and the cabin exit buffer block respectively play a buffering role at the beginning and end of the cross slider stroke.

[0024] Furthermore, the water speed meter probe is mainly used to measure the speed relative to the water body. It can convert the water speed dynamic information into a speed signal by using the principle of the built-in differential pressure sensor, and transmit the water speed signal to the control board through the probe connecting cable.

[0025] Furthermore, the protection and sealing mechanism is to protect the internal structure from the influence of the external environment of the cabin (such as water pressure, corrosion, etc.) to prevent leakage of the cabin when the water velocity meter probe is in working state and when entering and exiting the cabin. The protection and sealing mechanism is composed of a shield, a clamping nut, an O-ring, and a flange from top to bottom. The shield is installed on the upper part of the flange to protect the connection and fixing guide mechanism and the water velocity meter probe. Three groups of O-rings are arranged inside the flange. The O-rings are sealed by the cooperation with the outer cylindrical surface of the water velocity meter probe. The sealing of the protection and sealing mechanism is adjusted by adjusting the degree of compression of the O-ring by the clamping nut.

[0026] Implementation process of the function of electrically controlling the water speed meter probe to enter and exit the cabin: Power on the entire device. After the control and feedback system detects the induction signals of the in-cabin position sensor and the out-cabin position sensor, it judges the real-time position of the water speed meter probe. The initial state of the water speed meter probe is "entering the cabin". If the water speed meter probe is not in the "entering the cabin" state, the control and feedback system automatically restores the water speed meter probe to the initial state to complete the system preparation work. The external signal sends an "exit the cabin" command to the control and feedback system through the electrical connector. The control and feedback system drives the motor screw to rotate counterclockwise. The screw nut converts the rotational motion of the screw into a linear motion of the water speed meter probe installed at the end of the connection and fixed guiding mechanism outward until the out-cabin position sensor of the control and feedback system senses that the water speed meter probe has reached the end of the stroke and the motor stops rotating. The "exit the cabin" speed of the water speed meter probe is proportional to the motor speed. The "exit the cabin" distance of the water speed meter probe is controlled by the number of motor rotation turns × the screw lead. The water speed meter probe can stop at any point within the stroke range, and the out-cabin distance is adjustable. After the water speed measurement task is completed, the external signal sends an "enter the cabin" command to the control and feedback system through the electrical connector. The control and feedback system drives the motor screw to rotate clockwise. The screw nut converts the rotational motion of the screw into a linear motion of the water speed meter probe installed at the end of the connection and fixed guiding mechanism inward until the in-cabin position sensor of the control and feedback system senses that the water speed meter probe has been retracted to the starting point of the stroke and the motor stops rotating. Thus, a complete cycle of the function of entering and exiting the cabin is completed.

[0027] The layout method of the device structure for electrically controlling the water speed meter probe to enter and exit the cabin from top to bottom arranges the parts with certain emphasis on waterproof sealing, such as the control and feedback system and the driving mechanism, at the top of the device to avoid being affected by the humid environment at the bottom of the cabin. The overall structure planning is clear, with distinct levels. The relationship between each part is close and reasonable, effectively improving the overall stability and reliability of the device.

[0028] The driving mechanism selects the cooperation of the motor, screw, and screw nut for transmission as the power source of the device. It has high positioning accuracy and can achieve precise linear motion control; high transmission efficiency, which can effectively convert the rotational motion of the motor into a linear motion; strong load-bearing capacity, can bear a large load, and is suitable for heavy-duty working conditions; good stability, with smooth motion and no obvious impact and vibration, which can ensure the motion stability of the water speed meter probe during the process of entering and exiting the cabin; reversibility, can achieve forward and reverse linear motions, with flexible operation; compact structure, relatively small occupied space, easy to install and integrate; fast response speed, can quickly respond to control signals, and achieve rapid positioning and adjustment of the water speed meter probe; high reliability, because the structure is relatively simple and there are few transmission parts, reducing the frequency of failures and improving the reliability and service life of the system; good repeatability, with high consistency and repeatability of the stroke and performance of each motion, which is conducive to ensuring the water speed measurement performance.

[0029] The connecting and fixing guiding mechanism adopts a cage structure for the moving part. The cross slider and the probe connecting fixing plate are connected and fixed by four guiding connecting rods, which are arranged at an angle of 90°. This not only transmits the driving force but also overcomes the deflection force generated by the rotation of the connecting and fixing guiding mechanism with the motor, playing a guiding role and ensuring that the connecting and fixing guiding mechanism can stably and reliably transmit the driving force generated by the driving mechanism to the water velocity meter probe along a straight line, ensuring the smooth process of the water velocity meter probe entering and leaving the cabin.

[0030] In the protection and sealing mechanism, the sealing effect is mainly ensured by the elastic deformation of the O-ring. With the change of the environment and the passage of time, the O-ring material ages, is corroded by the medium, and has compression permanent deformation, etc., resulting in sealing failure. During the daily maintenance of the water velocity meter, the overall sealing performance of the protection and sealing mechanism can be adjusted by adjusting the compression nut to squeeze the deformation degree of the O-ring.

[0031] The utility model controls the process of the water velocity meter probe entering and leaving the cabin electrically, can realize remote operation, reduce direct manual intervention, and improve the convenience and efficiency of operation; the driving mechanism uses a motor, a lead screw and a lead screw nut for cooperative transmission, can more accurately control the speed and distance of the water velocity meter probe entering and leaving the cabin, ensure the measurement accuracy and stability; can be integrated with other automation systems to realize the automation of the whole monitoring process and reduce human errors; meet the needs of the electric control water velocity meter in more high-end environments.

[0032] The above are only the preferred embodiments of the utility model. It should be noted that for those of ordinary skill in the art, without departing from the principle of the utility model, several improvements and retouches can be made, and these improvements and retouches should also be regarded as the protection scope of the utility model.
