Description

A portable sonar draft measurement device Technical Field

[0001] This utility model relates to the field of ship measurement technology, and in particular to a convenient sonar draft measurement device. Background Technology

[0002] A portable sonar draft measurement device is a tool used for measuring water depth using sonar technology. It measures water depth by emitting sound waves underwater and receiving the reflected sound waves. This portable device allows for convenient water depth measurements at various locations. It typically includes a sonar transmitter and a receiver, as well as a processor to analyze and display the measurement results. Portable sonar draft measurement devices have wide applications in water depth measurement in oceans, rivers, lakes, and other bodies of water. Furthermore, it can be used for measuring the draft of ships, docks, and other water engineering projects to ensure safe passage and operation.

[0003] Chinese utility model patent CN205311857U discloses a sonar installation mechanism for a shipborne draft measurement device. It includes a positioning device, a support device, a high-density sonar array, and a high-density sonar array support installation device. The support device is installed on the bottom of the hull using the positioning device. The high-density sonar array is installed between the positioning device and the support device using the high-density sonar array support installation device. The positioning device enables automatic installation and positioning of the support device. A support adjustment ring and a support fixing plate fix the support device between the bottom plate and the deck of the measuring vessel. The installation angle of the high-density sonar array is adjusted, and the support device is locked, thus achieving a rigid connection between the underwater high-density sonar array and the measuring vessel. This installation mechanism is simple, practical, easy to install and maintain, and saves significant manpower and resources.

[0004] The technology has at least the following problems: the sonar installation mechanism installs the sonar underwater using bolts and support devices, which fixes the installation position of the sonar and makes it inconvenient to adjust the installation height of the sonar, thus reducing the flexibility of use. Therefore, a convenient sonar draft measurement device is proposed to solve the problems mentioned above. Summary of the Invention

[0005] To address the shortcomings of existing technologies, this application provides a convenient sonar draft measurement device, which has advantages such as easy height adjustment. It solves the problem that the sonar installation mechanism of existing shipborne draft measurement devices has a fixed installation position, making it inconvenient to adjust the installation height of the sonar.

[0006] In summary, this application provides the following technical solution: a portable sonar draft measurement device, comprising a fixed plate, a support rod fixedly connected to the bottom of the fixed plate, a mounting frame disposed on the outside of the support rod, and a sonar measurement device body fixedly mounted on the outside of the mounting frame. A sliding component is provided between the mounting frame and the support rod, and a lifting mechanism is provided on the outside of the fixed plate.

[0007] The sliding assembly includes a counterweight and a sliding sleeve fixedly connected to the outside of the counterweight. The sliding sleeve is sleeved on the outside of the support rod and fixedly connected to the mounting bracket.

[0008] The lifting mechanism includes a housing fixedly installed on the top of the fixed plate, a motor fixedly installed inside the housing, a shaft fixedly connected to the output shaft of the motor, a transmission wheel fixedly installed on the outside of the shaft, and a traction rope wound around the outside of the transmission wheel.

[0009] The end of the traction rope away from the transmission wheel is fixedly connected to the counterweight, and a limit mechanism is provided on the outer side of the shaft.

[0010] By adopting the above-mentioned technical solution, the lifting mechanism can drive the sliding component to move up and down along the outer wall of the support rod, thereby driving the mounting frame and the sonar measuring device body to move up and down synchronously. This allows for adjustment of the installation height of the sonar measuring device body according to the size of the ship being measured, improving installation flexibility, facilitating maintenance, and enhancing practicality.

[0011] Furthermore, the limiting mechanism includes an electric push rod fixedly installed on the upper side of the housing, a limiting gear connected to the electric push rod, and a movable gear fixedly connected to the outside of the shaft, wherein the movable gear meshes with the limiting gear.

[0012] The beneficial effect of adopting the above-mentioned further solution is that the height of the limit gear can be adjusted by driving the electric push rod. When the limit gear moves upward, it will separate from the movable gear, so that the movable gear can rotate with the shaft.

[0013] Furthermore, the end of the shaft away from the motor is connected to the inner wall of the housing via a bearing, and the traction rope extends to the lower side of the fixed plate.

[0014] The beneficial effect of adopting the above-mentioned further solution is that the bearing provides rotational support for the shaft, thereby improving the stability of the structure.

[0015] Furthermore, the motor is a self-locking motor, and the density of the counterweight is greater than that of water.

[0016] The beneficial effects of adopting the above-mentioned further solution are: since the motor is a self-locking motor, when the motor stops running, its output shaft can lock itself, thereby restricting the rotation of the shaft. Since the density of the counterweight is greater than that of water, the counterweight can sink stably in the water.

[0017] Furthermore, a pulley is rotatably mounted on the inner wall of the sliding sleeve, and a rolling groove adapted to the pulley is formed on the outer wall of the support rod.

[0018] The beneficial effect of adopting the above-mentioned further solution is that the cooperation between the pulley and the rolling groove enables the sliding sleeve to move stably up and down along the outer wall of the support rod, thereby improving the stability of the structure.

[0019] Furthermore, there are two sliding sleeves, and each sliding sleeve contains two pulleys.

[0020] The beneficial effect of adopting the above-mentioned further solution is that the two pulleys inside the sliding sleeve facilitate the reduction of friction between the sliding sleeve and the support rod, thereby improving the sliding effect.

[0021] Furthermore, a connecting plate is fixedly connected to the output shaft of the electric push rod, and the limiting gear is fixedly connected to one end of the connecting plate.

[0022] The beneficial effect of adopting the above-mentioned further solution is that since the limiting gear and the connecting plate are fixed, the limiting gear cannot rotate. When the non-rotating limiting gear meshes with the movable gear, its rotation can be restricted, which facilitates the restriction of shaft rotation.

[0023] Furthermore, a slider is fixedly connected to one end of the connecting plate away from the limiting gear, and a guide rail is fixedly installed inside the housing, with the slider slidably connected to the inner side of the guide rail.

[0024] The beneficial effect of adopting the above-mentioned further solution is that the cooperation between the slider and the guide rail can guide the connecting plate, enabling the connecting plate to maintain a stable motion trajectory and improving the stability of the structure.

[0025] Compared with the prior art, this application provides a convenient sonar draft measurement device, which has the following advantages:

[0026] 1. This portable sonar draft measurement device, through its lifting mechanism, can drive the sliding component to move up and down along the outer wall of the support rod, thereby causing the mounting frame and the sonar measurement device body to move up and down synchronously. This facilitates the adjustment of the installation height of the sonar measurement device body according to the size of the ship being measured, improving installation flexibility, ease of use, and high practicality. It solves the problem of the fixed installation position of the sonar installation mechanism in existing shipborne draft measurement devices, which makes it inconvenient to adjust the installation height of the sonar.

[0027] 2. This portable sonar draft measurement device uses a lifting mechanism to adjust the installation height of the sonar measurement device body, which facilitates the rapid pulling of the mounting frame from underwater to the water surface, making it easier to inspect and maintain the sonar measurement device body on the mounting frame and improving convenience.

[0028] 3. This portable sonar draft measurement device uses a limiting mechanism to restrict the rotation of the shaft. At the same time, the motor is a self-locking motor, and its output shaft can lock itself when the motor stops running. With the cooperation of the self-locking motor and the limiting mechanism, the shaft can be fixed to prevent the transmission wheel from rotating and keep the position of the counterweight below stable.

[0035] Please refer to Figure 1. A portable sonar draft measurement device in this embodiment includes a fixed plate 1, a support rod 2 fixedly connected to the bottom of the fixed plate 1, a mounting frame 3 located on the outside of the support rod 2, and a sonar measurement device body 4 fixedly installed on the outside of the mounting frame 3.

[0036] Referring to Figures 1 and 3, in this embodiment, a sliding assembly is provided between the mounting frame 3 and the support rod 2. The sliding assembly includes a counterweight 6 and a sliding sleeve 5 fixedly connected to the outside of the counterweight 6. The sliding sleeve 5 is fitted onto the outside of the support rod 2 and fixedly connected to the mounting frame 3. A pulley 18 is rotatably mounted on the inner wall of the sliding sleeve 5, and a rolling groove adapted to the pulley 18 is formed on the outer wall of the support rod 2. There are two sliding sleeves 5, and each sliding sleeve 5 contains two pulleys 18. The cooperation of the pulleys 18 and the rolling groove allows the sliding sleeve 5 to move stably up and down along the outer wall of the support rod 2, improving the stability of the structure. The two pulleys 18 inside the sliding sleeve 5 help reduce the friction between the sliding sleeve 5 and the support rod 2, improving the sliding effect.

[0037] Please refer to Figures 1-2. In this embodiment, a lifting mechanism is provided on the outer side of the fixed plate 1. The lifting mechanism includes a housing 7 fixedly installed on the top of the fixed plate 1, a motor 8 fixedly installed inside the housing 7, a shaft 9 fixedly connected to the output shaft of the motor 8, a transmission wheel 10 fixedly installed on the outer side of the shaft 9, and a traction rope 11 wound around the outer side of the transmission wheel 10. The end of the shaft 9 away from the motor 8 is connected to the inner wall of the housing 7 via a bearing. The traction rope 11 extends to the lower side of the fixed plate 1, providing rotational support for the shaft 9 through the bearing, thus improving the stability of the structure.

[0038] It should be noted that motor 8 is a self-locking motor. Because motor 8 is a self-locking motor, its output shaft can lock itself after motor 8 stops running, thereby restricting the rotation of shaft 9. In addition, the material of counterweight 6 can be concrete, lead block, etc., so that the density of counterweight 6 is greater than that of water, allowing counterweight 6 to sink stably in water.

[0039] It should be noted that the end of the traction rope 11 away from the transmission wheel 10 is fixedly connected to the counterweight 6, and a limit mechanism is provided on the outer side of the shaft 9.

[0040] Please refer to Figures 2 and 4. In this embodiment, the limiting mechanism includes an electric push rod 12 fixedly installed on the upper side of the housing 7, a limiting gear 14 connected to the electric push rod 12, and a movable gear 15 fixedly connected to the outside of the shaft 9. The movable gear 15 meshes with the limiting gear 14. A connecting plate 13 is fixedly connected to the output shaft of the electric push rod 12, and the limiting gear 14 is fixedly connected to one end of the connecting plate 13.

[0041] It is understandable that the height of the limiting gear 14 can be adjusted by driving the electric push rod 12. When the limiting gear 14 moves upward, it will separate from the movable gear 15, allowing the movable gear 15 to rotate with the shaft 9. Since the limiting gear 14 is fixed to the connecting plate 13, the limiting gear 14 cannot rotate. When the non-rotating limiting gear 14 meshes with the movable gear 15, it can restrict its rotation, which facilitates restricting the rotation of the shaft 9.

[0042] It should be added that a slider 16 is fixedly connected to the end of the connecting plate 13 away from the limiting gear 14, and a guide rail 17 is fixedly installed inside the housing 7. The slider 16 is slidably connected to the inner side of the guide rail 17. The cooperation between the slider 16 and the guide rail 17 can guide the connecting plate 13, so that the connecting plate 13 can maintain a stable movement trajectory and improve the stability of the structure.

[0043] The working principle of the above embodiments is as follows:

[0044] In use, the electric push rod 12 is activated to move the connecting plate 13 upward, causing the limiting gear 14 to separate from the movable gear 15. Then, the motor 8 is activated to rotate the shaft 9, which in turn drives the transmission wheel 10 and the movable gear 15 to rotate. The transmission wheel 10 is used to wind or unwind the traction rope 11, thereby causing the counterweight 6 to move up and down, and causing the sliding sleeve 5 to move stably along the outer wall of the support rod 2. This causes the sonar measuring device body 4 to move up and down. After the sonar measuring device body 4 is adjusted to a suitable height, the motor 8 is turned off, and the motor 8 self-locks to limit the rotation of the shaft 9. At the same time, the electric push rod 12 is activated to move the connecting plate 13 downward, so that the limiting gear 14 and the movable gear 15 remain engaged, thereby limiting the shaft 9 and keeping the position of the counterweight 6 stable in the water, thus completing the adjustment of the height of the sonar measuring device body 4.
