Description

Technical Field

[0001] The invention belongs to the field of water depth monitoring devices, and in particular relates to a real-time water depth monitoring device for port and navigation engineering. Background Art

[0002] In the complex and critical field of port and shipping engineering, real-time water depth monitoring plays a crucial role. It is not only a core element in ensuring safe and stable navigation for ships, but also an indispensable support for the smooth conduct of various loading, unloading, and transshipment operations within the port, as well as the daily maintenance and scientific management of waterways.

[0003] Based on this, various types of real-time water depth monitoring devices have begun to appear on the market. For example, the Chinese patent with publication number CN215865400U proposes a real-time monitoring device for the water depth of a port channel. The device is based on a floating plate, on which a limiting slide is provided, and is used to install a moving mechanism and a monitoring body. At the same time, the device is also equipped with a protective cover on the outside of the floating plate to protect the internal components. A support rod with a counterweight plate and a scraper needle is connected to both ends of the floating plate through a fixed seat, and the scraper needle is designed to be conical. At this time, in its actual water depth monitoring operation, it mainly relies on the cooperation of the counterweight plate and the scraper needle to fix the entire device to the bottom of the water, and calculates the water depth at the location through the monitoring body.

[0004] However, the device has exposed many problems in actual use. The most serious safety hazard is the carrying process: because the scraping needle is directly external, workers can easily be accidentally scratched by the sharp scraping needle during handling and transportation, posing a significant threat to their personal safety. Summary of the Invention

[0005] The purpose of the present invention is to address the problem that existing real-time water depth monitoring devices have serious safety hazards when in use. The present invention proposes and designs a real-time water depth monitoring device for port and shipping projects, which can not only realize the accurate water depth monitoring function, but also effectively avoid the problem of accidental injury to workers due to the external scraper needle during carrying.

[0006] In order to achieve the above-mentioned purpose, the technical solution provided by the present invention is: a real-time monitoring device for water depth of port and shipping projects, which includes a fixed box, two water depth measuring rods are arranged in parallel at the lower end of the fixed box, the outer sides of the two water depth measuring rods are provided with water depth scale values, and the lower ends of the two water depth measuring rods are commonly connected to a protective plate; the surface of the protective plate is penetrated by a through hole, and a cross plate is arranged above the protective plate, and the two ends of the cross plate are vertically slidably installed on the corresponding water depth measuring rods, and the cross plate is in contact with the outer wall of the water depth measuring rod; at least two plug rods are fixedly installed at the lower end of the middle part of the cross plate, and the lower ends of the plug rods can extend out of the protective plate through the through holes; the upper end of the middle part of the cross plate is fixedly installed with a threaded tube, and the inner thread of the threaded tube is connected to a joystick, and the upper end of the joystick is provided with a joystick after passing through the fixed box. At this time, on the one hand, the present invention can provide an intuitive data reading method for water depth measurement through two parallel depth measuring rods with water depth scale values marked on the outside, thereby facilitating the staff to read the water depth data in real time; on the other hand, during the installation of the device, it can control the horizontal plate to slide vertically on the water depth measuring rod by rotating the operating part, thereby conveniently controlling the lifting and lowering of the horizontal plate and the insertion rod, so that the insertion rod passes through the through hole on the protective plate for fixing operation, so as to fix the entire device to the bottom of the water; in the process of transporting the entire device, the insertion rod is effectively blocked by the protective plate connected to the lower end of the water depth measuring rod, avoiding accidental injury to the staff due to accidental extension of the insertion rod, thereby greatly improving the safety of the device during carrying, and providing an efficient and safe solution for the real-time monitoring of water depth in port and shipping projects.

[0007] Furthermore, a depth measuring rod verticality detection component is provided in the fixed box, and the verticality of the depth measuring rod is monitored by the depth measuring rod verticality detection component to ensure that the depth measuring rod is in a vertical state during operation, thereby effectively avoiding measurement errors caused by depth measuring rod posture problems, greatly improving the accuracy of the entire device during the depth measurement process, providing more reliable depth data for port and shipping projects, and effectively ensuring the safety of ship navigation and the smooth progress of various operations.

[0008] Furthermore, the verticality detection assembly of the water depth measuring rod includes a winding rod rotatably installed in a fixed box and a guide member installed on the wall of the fixed box, a driven gear is fixedly installed on the lower part of the winding rod, the driven gear is engaged with a driving gear, the driving gear is fixedly installed on the joystick and is located in the fixed box; a pull rope is wound around the upper part of the winding rod, one end of the pull rope is connected to a laser indicator after passing through the guide member; the verticality detection assembly of the water depth measuring rod also includes a transparent tube fixedly installed under the fixed box, the top of the transparent tube is connected to the inner cavity of the fixed box, and an observation plate is provided at the bottom of the transparent tube; a fixed plate is provided in the middle of the inner cavity of the transparent tube, and a light-through hole is passed through the middle of the fixed plate; when the pull rope is released after the winding rod is rotated, the laser indicator enters the transparent tube; when the water depth measuring rod is in a vertical state, the light output by the laser indicator can pass through the light-through hole and shine on the observation plate. At this time, the present invention achieves flexible retraction and extension of the pull rope through the clever coordination of the winding rod, guide, driven gear, driving gear and joystick, thereby accurately controlling the position of the laser indicator; that is, when the joystick is rotated, while the horizontal plate is lifted, the driving gear drives the driven gear to rotate, causing the winding rod to rotate and release the pull rope, allowing the laser indicator to smoothly enter the transparent tube. At the same time, the present invention constructs an intuitive and reliable observation system for detecting the verticality of the water depth measuring rod through the combination of the transparent tube, the fixed plate and the observation plate. That is, when the light output by the laser indicator is in a vertical state and passes through the light hole to illuminate the observation plate, it can indicate that the water depth measuring rod is in a vertical state. Otherwise, it can be adjusted in time according to the light deviation. This design not only accurately detects the verticality of the water depth measuring rod and ensures the accuracy of the water depth measurement, but also provides a convenient and clear observation method for staff, greatly improving the reliability and operational convenience of the entire port and navigation project water depth real-time monitoring device, and effectively ensuring the efficient implementation of the port and navigation project water depth monitoring work.

[0009] Furthermore, the guide member is a fixed pulley, which is arranged vertically opposite the transparent tube and rotatably mounted on the wall of the fixed box. One end of the pull rope passes around the fixed pulley and is wound around the winding rod, while the other end of the pull rope passes around the fixed pulley and is connected to the laser pointer. The present invention utilizes the fixed pulley to cleverly change the direction of the pull rope's movement and reduce friction during operation, allowing one end of the pull rope to easily pass around the fixed pulley and smoothly wrap around the winding rod, while the other end can also stably pass around the fixed pulley and connect to the laser pointer. This ensures smooth and fluid movement of the pull rope and greatly improves the reliability of the pull rope's operation. Furthermore, the guiding action of the fixed pulley allows the laser pointer to accurately fall into the transparent tube under the pull rope's traction, providing an accurate measurement benchmark for real-time water depth monitoring in port and navigation projects. This significantly improves the measurement accuracy and operating efficiency of the entire monitoring device, providing more reliable data support for port and navigation project operations.

[0010] Furthermore, the guide member is a vertically placed guide tube, one end of the pull rope passes through the guide tube and is wound around the winding rod, and the other end of the pull rope passes through the guide tube and is connected to the laser indicator; the guide tube is vertically placed in the fixed box through a connecting rod, the position of the guide tube is adapted to the position of the transparent tube, and the connecting rod preferably adopts an L-shaped structure, and the shape of the guide tube and the shape of the transparent tube are preferably cylindrical, and at this time the axis of the guide tube is aligned with the axis of the transparent tube. At this time, the present invention can provide a precise guide path for the pull rope through the guide tube, effectively avoiding the pull rope from being entangled, offset, etc. during movement, ensuring that one end of the pull rope can be smoothly wound around the winding rod, and the other end is stably connected to the laser indicator, ensuring the stability and reliability of the pull rope operation, thereby avoiding the problem of the laser indicator getting stuck in the transparent tube, and providing an accurate measurement benchmark for real-time monitoring of the water depth of port and shipping projects, greatly improving the measurement accuracy and work efficiency of the entire monitoring device.

[0011] Furthermore, a counterweight is connected between the pull rope and the laser pointer, or the laser pointer is equipped with a counterweight to ensure that the laser pointer can move smoothly downward under the action of gravity. When a counterweight is connected between the pull rope and the laser pointer, the counterweight can be first secured to the pull rope, and then connected to the laser pointer using a connecting rope. The counterweight is preferably shaped like an inverted cone, with a larger top and a smaller bottom.

[0012] Furthermore, two depth-of-water rod verticality detection assemblies are installed within the fixed box, symmetrically positioned on either side of the control rod. This allows the present invention to more accurately detect changes in the verticality of the depth-of-water rod under different operating conditions through the coordinated operation of the two assemblies. Furthermore, its symmetrical structure ensures balanced force across the entire device.

[0013] Furthermore, the transparent tube is equipped with a drying assembly that continuously and effectively removes moisture from the air inside the tube, preventing condensation caused by high humidity. This prevents the laser pointer inside the tube from shorting out due to moisture, significantly extending the laser pointer's service life and ensuring stable operation. Furthermore, the dry environment ensures the accuracy of water depth measurement data, avoiding errors caused by moisture interfering with optical or electronic measurement principles.

[0014] Furthermore, the drying assembly includes a drying cylinder fixedly mounted at the lower end of the fixed housing. The interior of the drying cylinder is filled with desiccant. A connecting pipe is provided at the upper end of the drying cylinder, and a filter is installed within the connecting pipe. The connecting pipe connects the transparent cylinder and the drying cylinder. In this case, the desiccant filled in the drying cylinder continuously absorbs moisture from the air, reducing humidity within the transparent cylinder. Simultaneously, the filter installed within the connecting pipe effectively blocks desiccant particles from entering the transparent cylinder, creating a dry and refreshing working environment for the laser pointer within the transparent cylinder, preventing malfunctions due to moisture, and effectively avoiding deviations in water depth measurement data caused by moisture interfering with the measurement principle.

[0015] Furthermore, a vertical rod is rotatably mounted at the bottom of the drying cylinder. A stirring rod is fixedly mounted after the upper end of the vertical rod extends into the drying cylinder. A pneumatic plate is fixedly mounted after the lower end of the vertical rod extends out of the drying cylinder. The pneumatic plate can rotate in response to the flow of water or air, and drive the vertical rod to rotate together. At this time, the stirring rod fixed at the upper end of the vertical rod then operates in the drying cylinder and stirs the desiccant filled in the drying cylinder to solve the problem of local adsorption saturation of the desiccant after being left still for a long time. This allows all parts of the desiccant to fully and evenly contact the moist air, continuously maintaining a strong moisture absorption capacity, and greatly enhancing the overall drying efficiency of the drying cylinder. Moreover, by continuously stirring the desiccant, the present invention can make the desiccant work more efficiently, avoid affecting the overall drying effect due to the failure of some desiccant, ensure that the interior of the transparent cylinder always remains dry, and provide a more stable and reliable operating environment for the laser pointer in the transparent cylinder.

[0016] It can be seen from the above technical solutions that the present invention has the following advantages: 1. The present invention can provide an intuitive data reading method for water depth measurement by using two parallel depth measuring rods with water depth scale values marked on the outside, thereby facilitating workers to read water depth data in real time; 2. During the installation of the device, the horizontal plate can be controlled to slide vertically on the water depth measuring rod by rotating the operating part, thereby conveniently controlling the lifting and lowering of the horizontal plate and the insertion rod, so that the insertion rod passes through the through hole on the protective plate for fixing operation, thereby fixing the entire device to the bottom of the water; during the transportation of the entire device, the protective plate connected to the lower end of the water depth measuring rod effectively blocks the insertion rod, preventing accidental injury to workers due to accidental extension of the insertion rod, thereby greatly improving the safety of the device during transportation; 3. The present invention can monitor the verticality of the depth measuring rod through the depth measuring rod verticality detection component to ensure that the depth measuring rod is in a vertical state during operation, thereby effectively avoiding measurement errors caused by the depth measuring rod posture problem, greatly improving the accuracy of the entire device during the depth measurement process, providing more reliable water depth data for port and shipping projects, and effectively ensuring the safety of ship navigation and the smooth implementation of various operations; 4. The present invention can continuously and effectively remove moisture from the air in the transparent tube through the drying component, preventing water vapor condensation caused by high humidity, thereby avoiding problems such as short circuits in the laser pointer in the transparent tube due to moisture, thereby greatly extending the service life of the laser pointer and ensuring the stability of equipment operation. At the same time, the dry environment can ensure the accuracy of water depth measurement data and avoid errors caused by moisture interfering with optical or electronic measurement principles.

DETAILED DESCRIPTION

[0020] In order to make the purpose, features, and advantages of the present invention more obvious and easy to understand, the technical solutions of the present invention will be clearly and completely described below in conjunction with the drawings in this specific embodiment. Obviously, the embodiments described below are only part of the embodiments of the present invention, not all of them. Based on the embodiments in this patent, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of this patent.

[0021] like Figures 1 to 6 As shown, the present invention provides a real-time monitoring device for water depth of a port and navigation project, which includes a fixed box 1, and two water depth measuring rods 2 are arranged in parallel at the lower end of the fixed box 1. The outer sides of the two water depth measuring rods 2 are provided with water depth scale values, and the water depth scale values provide an intuitive data reading method for the monitored water depth, so as to facilitate the staff to read the water depth data in real time.

[0022] At the same time, the lower ends of the two depth measuring rods 2 are connected to a common protective plate 5, which has a through hole in its surface. A horizontal plate 3 is provided above the protective plate 5. The ends of the horizontal plate 3 are sleeved on the lower parts of the two depth measuring rods 2 and can slide vertically along the corresponding depth measuring rods 2. The horizontal plate 3 contacts the outer wall of the depth measuring rods 2. At least two insertion rods 4 are fixedly mounted at the lower end of the middle portion of the horizontal plate 3. The insertion rods 4 are preferably conical structures with a larger upper portion and a smaller lower portion. When the horizontal plate 3 moves downward along the depth measuring rods 2, the lower ends of the insertion rods 4 can extend through the through hole in the protective plate 5 to insert the entire device into the water bottom. When the horizontal plate 3 moves upward along the depth measuring rods 2, the lower ends of the insertion rods 4 can retract through the through hole to above the protective plate 5, where they are protected by the protective plate 5, preventing workers from coming into contact with the insertion rods 4 and causing accidental injury during the transportation of the device, thereby greatly improving the safety of the device during transportation. A threaded tube 8 is fixedly mounted on the upper end of the middle portion of the transverse plate 3, and a joystick 6 is connected to the inner thread of the threaded tube 8. An operating portion 18 is provided on the upper end of the joystick 6 after passing through the fixed box 1. By rotating the operating portion 18 of the joystick 6, the raising and lowering of the transverse plate 3 on the water depth measuring rod 2 can be precisely controlled to ensure that the insertion rod 4 can accurately reach the bottom of the water at the measuring position. At the same time, since the present invention sets the joystick 6 through the fixed box 1 and sets the operating portion 18 at the upper end of the joystick 6, the present invention not only provides a convenient operating interface for the staff and effectively improves the working efficiency; it can also prevent the transverse plate 3 from sliding freely by the contact friction between the joystick 6 and the box wall of the fixed box 1, and the contact friction between the transverse plate 3 and the water depth measuring rod 2.

[0023] In addition, as a preference, the present invention also provides a water depth measuring rod verticality detection assembly in the fixed box 1, and monitors the verticality of the water depth measuring rod 2 through the water depth measuring rod verticality detection assembly to ensure that the water depth measuring rod 2 is in a vertical state during operation, thereby effectively avoiding measurement errors caused by posture problems of the water depth measuring rod 2. At the same time, the number of the water depth measuring rod verticality detection assemblies is preferably two, and when the number of the water depth measuring rod verticality detection assemblies is two, the two water depth measuring rod verticality detection assemblies can be symmetrically arranged on both sides of the joystick 6, and the lower parts of the two water depth measuring rod verticality detection assemblies are connected to the two water depth measuring rods 2 through the long plate 9. At this time, the present invention can more accurately sense the verticality changes of the water depth measuring rod 2 under different working conditions through the coordinated work of the two water depth measuring rod verticality detection assemblies; and because it adopts a symmetrical structure, it can ensure that the entire device is balanced in force.

[0024] Specifically, if Figure 2 、 Figure 4 、 Figure 5 As shown, the water depth measuring rod verticality detection assembly includes a winding rod 15 rotatably mounted within a fixed box 1 and a guide member mounted on the wall of the fixed box 1. A driven gear 16 is fixedly mounted to the lower portion of the winding rod 15. The driven gear 16 meshes with a driving gear 14, which is fixed to the joystick 6 and located within the fixed box 1, and can rotate with the joystick 6. A pull rope 17 is wound around the upper portion of the winding rod 15. One end of the pull rope 17 passes through the guide member and is connected to a laser pointer 24. The guide member is a fixed pulley, which is rotatably mounted on the wall of the fixed box 1, and one end of the pull rope 17 is wound around the fixed pulley and then wound around the winding rod 15, and the other end of the pull rope 17 is connected to the laser indicator 24 after passing around the fixed pulley, thereby cleverly changing the movement direction of the pull rope 17 by using the fixed pulley and reducing the friction of the pull rope 17 during operation, so that one end of the pull rope 17 can easily pass around the fixed pulley and smoothly wind around the winding rod 15, and the other end can also stably pass around the fixed pulley and be connected to the laser indicator 24, thereby ensuring that the movement process of the pull rope 17 is smooth and smooth, greatly improving the reliability of the operation of the pull rope 17. Alternatively, the guide member is a vertically placed guide tube 21. In this case, one end of the pull rope 17 passes through the guide tube 21 and is wound around the winding rod 15, and the other end of the pull rope 17 passes through the guide tube 21 and is connected to the laser indicator 24; and the guide tube 21 is vertically placed in the fixed box 1 through the L-shaped connecting rod 20, and provides a precise guide path for the pull rope 17, effectively avoiding the pull rope 17 from being entangled, offset, etc. during movement, ensuring that one end of the pull rope 17 can be smoothly wound around the winding rod 15, and the other end is stably connected to the laser indicator 24, thereby ensuring the stability and reliability of the operation of the pull rope 17.

[0025] To ensure that the laser pointer 24 descends smoothly under the action of gravity, a counterweight 22 can be connected between the pull rope 17 and the laser pointer 24, or the counterweight 22 can be directly mounted on the laser pointer 24. When the counterweight 22 is connected between the pull rope 17 and the laser pointer 24, the counterweight 22 can be first secured to the pull rope 17 and then connected to the laser pointer 24 using a connecting rope 23. The counterweight 22 is preferably shaped like an inverted cone with a larger top and a smaller bottom.

[0026] The water depth measuring rod verticality detection assembly also includes a transparent tube 11 fixedly mounted below the fixed box 1, the top of the transparent tube 11 is connected to the inner cavity of the fixed box 1, and the bottom of the transparent tube 11 is provided with an observation plate 10; a fixed plate 12 is provided in the middle of the inner cavity of the transparent tube 11, and a light-through hole 13 is passed through the middle of the fixed plate 12; and when the staff rotates the joystick 6 to control the horizontal plate 3 to move downward, the winding rod 15 can rotate and release the pull rope 17 under the cooperation of the driving gear 14 and the driven gear 16. At this time, since the pull rope 17 between the guide and the laser pointer 24 becomes longer, the laser pointer 24 can It descends under the action of its own gravity and enters the transparent tube 11. The pull rope 17 between the guide and the laser pointer 24 can be in a vertical state under the action of the gravity of the laser pointer 24 and the counterweight 22. Moreover, if the water depth measuring rod 2 is in a vertical state, the vertical light output by the laser pointer 24 will pass through the light hole 13 and shine on the observation plate 10, so as to inform the staff that the water depth measuring rod 2 is in a vertical state at this time; on the contrary, if the water depth measuring rod 2 is in an inclined state, the vertical light output by the laser pointer 24 cannot pass through the light hole 13 and shine on the observation plate 10, so as to inform the staff that the water depth measuring rod 2 is not in a vertical state at this time.

[0027] In addition, as a preference, the present invention further provides a drying component at the transparent tube 11, and the drying component is used to continuously and effectively remove moisture from the air in the transparent tube 11, preventing condensation of water vapor due to high humidity, thereby avoiding problems such as short circuits in the laser pointer 24 in the transparent tube 11 due to moisture, thereby greatly extending the service life of the laser pointer 24, ensuring the stability of the equipment operation, and avoiding errors caused by moisture interfering with optical or electronic measurement principles.

[0028] Specifically, if Figure 4 、 Figure 6As shown, the drying component includes a drying cylinder 30 fixedly arranged at the lower end of the fixed box 1, a connecting pipe 25 is provided at the upper end of the drying cylinder 30, a filter screen 26 is provided inside the connecting pipe 25, and the connecting pipe 25 connects the transparent cylinder 11 and the drying cylinder 30; the inner cavity of the drying cylinder 30 is filled with a desiccant 27; the bottom end of the drying cylinder 30 is sealed with a blocking plate 32 through a rubber ring 33, and a vertical rod 28 is rotatably installed in the middle of the blocking plate 32, and the upper end of the vertical rod 28 is extended into the drying cylinder 30 and a stirring rod 29 is fixedly installed thereon, and the lower end of the vertical rod 28 is extended out of the drying cylinder 30 and a pneumatic plate 31 is fixedly installed thereon, and the pneumatic plate 31 can rotate along with the flow when water surges or air flows, and drive the vertical rod 28 to rotate together. At this time, the stirring rod 29 fixed at the upper end of the vertical rod 28 then rotates within the drying cylinder 30, stirring the desiccant 27 filled within the drying cylinder 30. The desiccant 27 filled within the drying cylinder 30 continuously absorbs moisture from the air, reducing the humidity within the transparent cylinder 11. This creates a dry and refreshing working environment for the laser pointer 24 within the transparent cylinder 11, preventing it from malfunctioning due to moisture, and effectively avoiding water depth measurement data deviations caused by moisture interfering with the measurement principle. At the same time, it can also solve the problem of local adsorption saturation of the desiccant 27 after being left stationary for a long time, allowing all parts of the desiccant 27 to fully and evenly contact the moist air, continuously maintaining a strong moisture absorption capacity, and greatly enhancing the overall drying efficiency of the drying cylinder 30. Moreover, the present invention can effectively prevent desiccant 27 particles from entering the transparent cylinder 11 through the filter 26 set inside the connecting pipe 25.

[0029] Based on this, when the present invention is used for water depth monitoring operations, it can not only realize the accurate water depth monitoring function, but also effectively avoid the problem of accidentally injuring the staff due to the external scraper needle during the carrying process. At the same time, it can also effectively avoid the measurement error caused by the posture problem of the water depth measuring rod 2, greatly improving the accuracy of the entire device in the water depth measurement process, providing more reliable water depth data for port and shipping projects, and effectively ensuring the safety of ship navigation and the smooth progress of various operations. In order to further improve the degree of automation of the present invention, it can also be provided with a floating plate between the two water depth measuring rods, and a through channel is reserved for the joystick in the middle of the floating plate, and a common electronic water level monitoring device on the market is provided at the upper end of the floating plate, such as the monitoring body mentioned in CN215865400U, and the monitoring body is used to assist in realizing the unmanned real-time monitoring function.

Various modifications to these embodiments will be readily apparent to one skilled in the art, and the general principles defined herein may be implemented in other embodiments without departing from the spirit or scope of the present invention. Therefore, the present invention is not limited to the embodiments shown herein but is intended to conform to the widest scope consistent with the principles and novel features disclosed herein.
