Description

Technical Field

[0001] This utility model relates to the field of marine engineering technology, and in particular to a navigation measurement device for ships. Background Technology

[0002] The purpose of ship navigation measurement devices is to accurately acquire key information such as a ship's position, course, and speed, ensuring safe navigation. They are of great significance, helping crew members accurately plan routes, avoid collisions and groundings, improve navigation efficiency, and also assisting maritime traffic management departments in effective supervision, ensuring maritime traffic order and playing a vital role in promoting maritime trade and maintaining maritime security.

[0003] As a crucial navigational measurement device for ships, the log is a core tool for measuring ship speed and distance. It accurately measures the ship's velocity relative to the water, converting this data into speed and distance readings. Among common types, electromagnetic logs are based on the principle of electromagnetic induction and offer stable measurements; Doppler logs utilize the Doppler effect and can adapt to various water depths; and acoustic correlation logs, thanks to acoustic correlation technology, can provide accurate measurements even in shallow water. These logs provide critical data support for ship navigation, route planning, and track calculation, ensuring safe and efficient navigation.

[0004] In existing technologies, some logs are typically fixedly connected to the testing equipment during use. This makes it difficult to disassemble and repair the log when it malfunctions, resulting in the inability to repair or replace the log in a timely manner. Consequently, the operator may not be able to detect navigation data, causing navigational difficulties. To address this issue, a navigation measurement device for ships is proposed. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a navigation measurement device for ships, which aims to improve the problem that in the prior art, the odometer is generally fixedly connected to the testing equipment during use, which makes it difficult to disassemble and repair the odometer when it malfunctions.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: A navigation measurement device for ships includes a fixed plate, a odometer detachably connected to the outer wall of the fixed plate, a screen installed on the inner wall of the odometer, a disassembly mechanism installed on the outer wall of the fixed plate, and a reciprocating assembly installed on the outer wall of the fixed plate. The disassembly mechanism includes a control rod, a fixed rod rotatably connected to the outer wall of the control rod, the outer wall of the fixed rod being fixedly connected to the outer wall of the fixed plate, a rotating rod rotatably connected to the outer wall of the control rod, sliding grooves being provided on the inner walls of both sides of the rotating rod, and a limit assembly being installed on the outer wall of the disassembly mechanism. Through the above technical solution: In the disassembly mechanism, the control rod can rotate around the fixed rod, and the rotating rod is rotatably connected to the control rod. The sliding grooves on both sides of the rotating rod can cooperate with the sliding blocks on the connecting plate to achieve sliding. The limiting component can limit the sliding of the connecting plate. When it is necessary to disassemble the odometer, the control rod is moved, and the rotating rod can drive the connecting plate to move, thereby separating the mounting bracket from the mounting plate and realizing the disassembly of the odometer. This makes the disassembly process more convenient. At the same time, the limiting component can ensure that the connecting plate slides stably in the sliding groove, improving the stability of the disassembly mechanism. Furthermore, the elastic spring can play a buffering and auxiliary connection role during disassembly and installation, facilitating the connection and separation of the mounting bracket and the mounting plate, and making it easier to install and disassemble the odometer.

[0007] As a further description of the above technical solution: The reciprocating assembly includes a mounting box, the outer wall of which is fixedly connected to the outer wall of the fixing plate, a drive motor is fixedly connected to the outer wall of the mounting box, and a half gear is fixedly connected to the drive end of the drive motor. Through the above technical solution: In the reciprocating assembly, the mounting box is fixed on the fixing plate, and the drive motor is installed on the outer wall of the mounting box. The drive end of the drive motor is connected to the half gear. When the screen needs to be cleaned, the drive motor starts, the half gear rotates, and the half gear can mesh with the teeth on the control board, thereby driving the control board to move, so that the cleaning squeegee can clean the screen. This design enables the cleaning squeegee to achieve reciprocating motion, thereby improving the cleaning effect and enabling long-term cleaning of the screen surface, avoiding screen surface contamination from affecting the data observed by the staff. In addition, the mounting box can protect the drive motor, half gear and other components, extending the service life of the device.

[0008] As a further description of the above technical solution: The inner wall of the mounting box is slidably connected to a control plate, and the inner wall of the control plate is fixedly connected to multiple teeth, the outer walls of the multiple teeth being meshed with the outer wall of the half gear. Through the above technical solution: the control board, which is slidably connected to the inner wall of the mounting box, has multiple teeth fixed on its inner wall that can mesh with the outer wall of the half gear. When the half gear rotates, it can drive the control board to slide on the inner wall of the mounting box. Since the control board moves once for every half rotation of the half gear, and moves once in the opposite direction when it rotates another half rotation, this reciprocating motion allows the cleaning squeegee to clean the screen surface repeatedly, ensuring thorough cleaning and effectively removing dirt from the screen surface. This improves the screen's clarity and helps staff to accurately observe data. Furthermore, the sliding connection between the control board and the inner wall of the mounting box ensures the stability of the control board's movement and improves the cleaning effect.

[0009] As a further description of the above technical solution: A cleaning squeegee is fixedly connected to the outer wall of the control panel, and the outer wall of the cleaning squeegee is in contact with the outer wall of the screen. The above technical solution involves a cleaning squeegee fixedly connected to the outer wall of the control board, whose outer wall contacts the outer wall of the screen. When the control board reciprocates within the mounting box, it drives the cleaning squeegee to clean the screen surface. The squeegee removes dust, stains, and other contaminants from the screen surface, thus keeping it clean and ensuring a clear display. This facilitates the observation of measurement data by staff. Furthermore, the contact method between the cleaning squeegee and the screen surface allows the squeegee to better adhere to the screen, improving the cleaning effect while preventing damage to the screen.

[0010] As a further description of the above technical solution: The limiting component includes a connecting plate, the outer wall of which is slidably connected to the inner wall of the sliding groove, sliding blocks are fixedly connected to both sides of the connecting plate, an elastic spring is fixedly connected to the top of the connecting plate, and a connecting rod is sleeved on the inner wall of the elastic spring. Through the above technical solution: In the limiting assembly, the outer wall of the connecting plate is slidably connected to the inner wall of the sliding groove, and the sliding blocks fixedly connected to both sides of the connecting plate can slide in the sliding groove, so that the connecting plate can slide stably in the sliding groove. The elastic spring fixedly connected to the top of the connecting plate has a connecting rod sleeved on its inner wall. The elastic spring can play a role in buffering and assisting the connection during the movement of the connecting plate. When the control lever is moved, the rotation of the rotating rod can drive the connecting plate to move. The elastic spring can provide a certain elastic force during the rising or falling of the connecting plate, which facilitates the movement of the connecting plate. At the same time, it can limit the movement of the connecting plate, ensuring that the connecting plate slides stably in the sliding groove. The connecting rod can slide in the elastic spring, which improves the stability of the connection between the connecting plate and the rotating rod and is conducive to the normal operation of the disassembly mechanism.

[0011] As a further description of the above technical solution: The top of the elastic spring is fixedly connected to the bottom of the rotating rod, and the top of the connecting rod is fixedly connected to a mounting bracket; The above technical solution involves: a spring fixedly connected to the top of a rotating rod at the bottom, and a mounting bracket fixedly connected to the top of a connecting rod. When the control lever is moved, the rotation of the rotating rod causes the connecting plate to rise, which in turn causes the mounting bracket to rise via the connecting rod, thus separating the mounting bracket from the mounting plate and enabling the disassembly of the odometer. During the installation of the odometer, the spring provides a certain amount of elasticity, facilitating the connection between the mounting bracket and the mounting plate. The spring also acts as a buffer for the mounting bracket, preventing hard collisions between them and protecting both the mounting bracket and the mounting plate. Simultaneously, the connecting rod ensures a stable connection between the mounting bracket and the connecting plate, improving the reliability of the disassembly mechanism.

[0012] As a further description of the above technical solution: The odometer is fixedly connected to mounting feet on both sides, and mounting plates are fixedly connected to the outer walls of the mounting feet. The inner wall of the mounting bracket is detachably connected to the inner wall of the mounting plate, and the outer wall of the mounting feet is fixedly connected to the outer wall of the odometer. The above technical solution involves mounting feet fixedly connected to both sides of the odometer, with a mounting plate fixedly connected to its outer wall that can be detachably connected to the inner wall of the mounting frame. When installing the odometer, the inner wall of the mounting frame can connect to the mounting plate, allowing the odometer to be stably mounted on the fixed plate. When disassembling the odometer, the control lever can be moved to separate the mounting frame from the mounting plate, facilitating the disassembly of the odometer. The mounting feet are fixedly connected to the outer wall of the odometer, ensuring the stability of the connection between the odometer and the mounting plate. Furthermore, the design of the mounting feet makes the odometer more securely mounted on the fixed plate, preventing the odometer from shaking or falling off during use and improving the reliability of the measuring device.

[0013] As a further description of the above technical solution: The outer wall of the mounting box is provided with a sliding groove, the outer wall of the cleaning scraper is slidably connected to the inner wall of the sliding groove, and the top of the mounting box is fixedly connected to a top plate.

[0014] The above technical solution involves a sliding groove on the outer wall of the mounting box, with the outer wall of the cleaning squeegee slidably connected to the inner wall of the groove. A top plate is fixedly connected to the top of the mounting box. The sliding groove limits the movement of the cleaning squeegee, ensuring that it does not deviate from its track during sliding, allowing it to accurately clean the screen. The top plate protects the components inside the mounting box, preventing dust and debris from entering and affecting the normal operation of components such as the drive motor and gears. The sliding connection between the groove and the cleaning squeegee makes the cleaning squeegee move more smoothly, improving the cleaning effect. At the same time, the top plate increases the structural strength of the mounting box, ensuring its stability.

[0015] This utility model has the following beneficial effects: 1. In this utility model, when the control lever is moved, it will rotate due to the restriction of the fixed lever. The rotation of the control lever will cause the rotating rod to move upward, thereby causing the sliding grooves on both sides of the rotating rod to drive the sliding block and the connecting plate to slide on the inner wall of the sliding groove. This causes the connecting plate to lift the connecting rod upward, so that the inner wall of the mounting bracket no longer abuts against the mounting plate, thereby realizing the removal of the mounting bracket from the outer wall of the mounting plate. This facilitates the removal of the odometer from the outer wall of the fixed plate by the mounting feet.

[0016] 2. In this utility model, the drive motor starts, which drives the half gear to rotate. The rotation of the half gear drives the control board to move through the meshing teeth. The half gear rotates half a turn and drives the control board to move once. When it rotates another half turn, it drives the control board to move in the opposite direction to the previous movement once. This reciprocating motion drives the cleaning scraper to reciprocate to clean the inner wall of the screen, thereby achieving long-term cleaning of the screen surface and preventing the contamination of the screen surface from affecting the data observed by the staff during long-term navigation.

[0025] Reference Figure 1 , Figure 4 and Figure 5The reciprocating assembly 3 includes a mounting box 31, which is used to mount the drive motor 32 and other components, providing protection and support. The outer wall of the mounting box 31 is fixedly connected to the outer wall of the fixing plate 1, so that the mounting box 31 is stably mounted on the fixing plate 1. The drive motor 32 is fixedly connected to the outer wall of the mounting box 31, and the drive motor 32 provides power to the reciprocating assembly 3.

[0026] Specifically, the reciprocating assembly 3 is composed of a mounting box 31, etc. The mounting box 31 is used to install the drive motor 32 and other components, and plays a protective and support role. Its outer wall is fixed on the fixing plate 1 to ensure stable installation. The drive motor 32 fixed on the outer wall of the mounting box 31 provides power to the assembly. The drive end of the drive motor 32 is connected to the half gear 33, which drives the half gear 33 to rotate. The control plate 35, which is slidably connected to the inner wall of the mounting box 31, meshes with the half gear 33 by the teeth 34 fixed on the inner wall and slides under the drive of the half gear 33 to realize the transmission of force.

[0027] The outer walls of multiple teeth 34 mesh with the outer walls of half gears 33, enabling the half gears 33 to drive the control plate 35 to move. A cleaning squeegee 36 is fixedly connected to the outer wall of the control plate 35. The cleaning squeegee 36 is used to clean the surface of the screen 4.

The top plate 6 on the top of the mounting box 31 protects the internal components of the box and prevents dust and debris from entering.

[0029] Working principle: When the speedometer 5 needs to be disassembled for maintenance, the control lever 21 is moved. Due to the restriction of the fixed rod 23, the control lever 21 will rotate. The rotation of the control lever 21 will cause the rotating rod 22 to move upward. This will cause the sliding grooves 24 on both sides of the rotating rod 22 to drive the sliding block 256 and the connecting plate 257 to slide on the inner wall of the sliding groove 24. This will cause the connecting plate 257 to lift the connecting rod 251 upward, so that the inner wall of the mounting bracket 255 no longer abuts against the mounting plate 254. This will allow the mounting bracket 255 to be disassembled from the outer wall of the mounting plate 254. This will facilitate the mounting foot 253 to drive the speedometer 5 to be disassembled from the outer wall of the fixed plate 1. The elastic spring 252 will facilitate the connecting plate 257 to pull the mounting bracket 255, thereby achieving the abutment of the mounting bracket 255 against the mounting plate 254.

[0030] When it is necessary to clean the surface of the screen 4 on the inner wall of the odometer 5, the drive motor 32 starts. The start of the drive motor 32 drives the half gear 33 to rotate. The rotation of the half gear 33 drives the control plate 35 to move through the meshing teeth 34. The half gear 33 rotates half a turn and drives the control plate 35 to move once. When it rotates another half turn, it drives the control plate 35 to move in the opposite direction to the previous movement once. This reciprocating motion drives the cleaning scraper 36 to reciprocate to clean the inner wall of the screen 4, thereby achieving long-term cleaning of the surface of the screen 4 and preventing the contamination of the surface of the screen 4 from affecting the observation data of the staff during long-term navigation.
