Description

Technical Field

[0001] This invention relates to the field of waterborne surveying equipment technology, and more particularly to a waterborne surveying equipment for engineering surveying. Background Technology

[0002] Maritime engineering surveying is an important means of obtaining underwater topographic and hydrological information. Traditional surveying vessels or small surveying platforms often face two major challenges: first, the platform is affected by wind, waves, and currents, causing it to sway and seriously affecting the data accuracy of onboard sensors such as depth sounders and sonars; second, they lack sufficient maneuverability and stability when facing complex aquatic environments (such as shallow beaches, reef areas, and weed beds).

[0003] Prior art reference document CN118494680A discloses a device with modular legs and a total stabilization mechanism. It adapts to the terrain through split legs and improves stability through an assembly that includes shock absorption devices and flow stabilization mechanisms. This invention provides a useful structural approach, but the connection between its leg mechanism and the main platform is relatively fixed, limiting its adaptability to dynamic waves. Its stabilization mechanism is mainly designed for static or slow-flow conditions, and its comprehensive shock suppression effect under complex disturbances needs to be improved.

[0004] In addition, most current surveying devices fix sensors directly to the hull, making it difficult to adjust the installation angle, and different sensors are prone to interference with each other. The overall draft of the platform is not adjustable, making it difficult to operate flexibly in waters with drastic changes in depth.

[0005] Therefore, it is necessary to develop a new type of waterborne surveying device with pure mechanical structural innovation as its core, so as to fundamentally improve its physical stability, environmental adaptability and ease of operation. Summary of the Invention

[0006] The purpose of this invention is to provide a waterborne surveying device for engineering surveying, which can solve the problems of most current surveying devices that directly fix sensors to the hull, making it difficult to adjust the installation angle and causing interference between different sensors. It also addresses the issue that the overall draft of the platform is not adjustable, making it difficult to operate flexibly in waters with drastic depth changes.

[0007] To achieve the above objectives, the present invention adopts the following technical solution: an engineering surveying waterborne surveying device, comprising a support platform, and further comprising: The main platform is fixedly installed on the outer side of the bottom end of the supporting platform; The secondary platform is located on both sides of the main platform. A connector is disposed on the inner side of one end of the sub-platform, and the connector is used to drive the sub-platform to perform horizontal and vertical multi-directional movements. Support legs are located on the inner side of the bottom end of the support platform; A support member is disposed on one side of the support leg.

[0008] In a preferred embodiment, the first slide rail is installed on the inner side of the sub-platform; The first slider is slidably disposed on the outer side of the top end of the first slide rail; The connecting rod is rotatably mounted on the outer sides of both ends of the first slider; A sleeve is slidably disposed on the outside of the connecting rod. The sleeve moves along the axial direction of the connecting rod, and the outer end of the sleeve away from the first slider is rotatably connected to the inner side of the sub-platform. The second slide rail is installed on the outer side of the top of the first slider; The second slider is slidably disposed on the outer side of the top end of the second slide rail. The outer ends of the two ends of the second slider are rotatably connected to another set of connecting rods and rod sleeves. The outer end of the rod sleeve away from the second slider is rotatably connected to the inner side of the sub-platform. The connecting block is fixedly mounted on the upper surface of the second slider.

[0009] In a preferred embodiment, a hydraulic buffer cylinder is rotatably disposed on the inner side of the end of the connecting block; The limiting leg sleeves are fixedly installed on the outer sides of both ends of the main platform, and the outer side of the end of the hydraulic buffer cylinder away from the connecting block is rotatably connected to the inner side of the end of the limiting leg sleeve.

[0010] In a preferred embodiment, a spring is fixedly provided on the outer side of the end of the connecting rod, and the outer side of the other end of the spring is connected to the inner side of the end of the rod sleeve.

[0011] In a preferred embodiment, a tail stabilizing fin is installed on the outer side of the bottom end of the sub-platform, and a bilge fin is fixedly installed on the lower surface of the sub-platform.

[0012] In a preferred embodiment, a drain valve is installed on the outer side of the bottom end of the sub-platform.

[0013] Its specific advantages are as follows: by adjusting the length of the support legs and the symmetrical support of the two sets of sub-platforms, the device can be quickly positioned and leveled; when the sub-platform is impacted by waves, it drives the first slider and the second slider to move along the first slide rail and the second slide rail, and with the elastic potential energy storage of the spring and the buffering effect of the hydraulic buffer cylinder, it can effectively offset the impact force of the waves.

[0014] As a preferred embodiment, the ladder is fixedly installed on the outer side of the bottom end of the support platform; The winch is fixedly installed on one side of the support platform.

[0015] In one preferred embodiment, a winch is installed on the upper surface of the support platform; A cable is installed on one side of the winch and passes through the support platform; The mounting frame is fixedly installed on the outer side of the bottom end of the cable.

[0016] Compared with the prior art, the advantages and positive effects of the present invention are as follows: With the adjustable length of the support legs and the symmetrical support of the two sets of auxiliary platforms, the device can be quickly positioned and leveled. When the auxiliary platforms are impacted by waves, they drive the first and second sliders to move along the first and second slide rails. Combined with the elastic potential energy storage of the springs and the buffering effect of the hydraulic buffer cylinders, the impact force of the waves can be effectively offset. At the same time, the fixed bilge fins increase roll damping, and the retractable tail stabilizing fins generate anti-water flow torque through angle adjustment, which greatly improves the device's anti-sway and heading stability in wind and waves, ensuring the accuracy of sensor mapping data. The support frame facilitates the device's support on shore, and the ladder facilitates personnel access to the support platform. The winch drives the cable to flexibly adjust the height of the installation frame. Its pre-set standardized quick-install interface with angle scale can quickly adapt to various mapping sensors such as depth sounders and side-scan sonars, meeting diverse mapping needs without additional modifications, significantly improving work efficiency and equipment versatility.

[0019] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention. Example 1

[0020] Please see Figures 1-5 This embodiment provides a stable engineering surveying waterborne surveying device, the specific concept of which is as follows: An engineering surveying waterborne surveying device includes a support platform 1, and the engineering surveying waterborne surveying device also includes a sub-platform 2 and connecting parts.

[0021] Among them, the main platform 101 is fixedly installed on the outer side of the bottom of the support platform 1, and the auxiliary platforms 2 are movably installed on the outer sides of both ends of the main platform 101. The two auxiliary platforms 2 are symmetrically distributed and can flexibly expand the working space according to the surveying and mapping needs. A connector is installed on the inner side of one end of the auxiliary platform 2. The connector can drive the auxiliary platform 2 to realize multi-directional movement such as horizontal extension and translation, and vertical lifting.

[0022] As examples, in this embodiment, the connector includes a first slide rail 201 and a first slider 202.

[0023] The inner side of the sub-platform 2 is equipped with a first slide rail 201, and the outer side of the top of the first slide rail 201 is slidably connected to a first slider 202. The cooperation between the first slide rail 201 and the first slider 202 provides precise horizontal movement guidance for the subsequent transmission components, ensuring the smoothness of the adjustment process. The outer sides of both ends of the first slider 202 are rotatably connected to a connecting rod 203, and the outer side of the connecting rod 203 is slidably connected to a rod sleeve 204. The rod sleeve 204 can move flexibly along the axial direction of the connecting rod 203, and the outer side of the end of the rod sleeve 204 away from the first slider 202 is rotatably connected to the inner side of the sub-platform 2, providing flexible support for the multi-directional movement of the sub-platform 2.

[0024] Meanwhile, a second slide rail 205 is installed on the outer top of the first slider 202, and a second slider 206 is slidably connected to the outer top of the second slide rail 205. Another set of connecting rods 203 and rod sleeves 204 are also rotatably connected to the outer ends of the two ends of the second slider 206. The outer end of the rod sleeve 204 away from the second slider 206 is rotatably connected to the inner side of the sub-platform 2. The combination design of the double slide rail and slider further expands the adjustment stroke and flexibility of the sub-platform 2, enabling it to achieve complex horizontal displacement.

[0025] A connecting block 207 is fixedly connected to the upper surface of the second slider 206. A hydraulic buffer cylinder 208 is rotatably connected to the inner side of the end of the connecting block 207. Limiting leg sleeves 301 are fixedly connected to the outer sides of both ends of the main platform 101. The outer side of the end of the hydraulic buffer cylinder 208 away from the connecting block 207 is rotatably connected to the inner side of the end of the limiting leg sleeve 301. The slider and connecting rod 203 assembly can be precisely driven by telescopic movement, thereby driving the secondary platform 2 to achieve horizontal telescopic and fine adjustment. At the same time, its buffering characteristics can offset the impact force brought by wind and waves on the water, avoid violent shaking during the adjustment process, and ensure the stability of the surveying equipment.

[0026] In addition, a spring 209 is fixedly connected to the outer end of the connecting rod 203. The outer end of the other end of the spring 209 is connected to the inner end of the rod sleeve 204. The spring 209 can use its own elastic potential energy to assist the rod sleeve 204 in resetting, and at the same time absorb the vibration energy during the transmission process, further improving the stability and service life of the adjustment structure. A tail stabilizing fin 210 is installed on the outer bottom end of the sub-platform 2, and a bilge fin 211 is fixedly connected to the lower surface of the sub-platform 2. The tail stabilizing fin 210 can effectively suppress the left and right swaying of the device in the water, while the bilge fin 211 can weaken the lateral rolling motion caused by waves. The synergistic effect of the two greatly improves the stability of the device in complex water environment and ensures the accuracy of the survey data acquisition.

[0027] In addition, a drain valve 212 is installed on the outer side of the bottom of the auxiliary platform 2. When water accidentally accumulates on the surface of the auxiliary platform 2, the water can be quickly drained through the drain valve 212 to avoid the water accumulation increasing the load on the device or affecting the safety of electrical equipment, and further adapting to the use needs of wet working environments on water. Example 2

[0028] Please see Figures 1-5 This embodiment provides a convenient-to-operate underwater surveying device for engineering surveying, the specific concept of which is as follows: An engineering surveying waterborne surveying device includes a support platform 1, and the engineering surveying waterborne surveying device also includes support legs 3 and support components.

[0029] Among them, the support leg 3 is located on the inner side of the bottom end of the support platform 1, and the support member is located on one side of the support leg 3.

[0030] As examples, in this embodiment, the support includes: a limiting leg sleeve 301 and a support frame 302.

[0031] Among them, a ladder 303 is fixedly connected to the outer side of the bottom of the support platform 1. The ladder 303 adopts an anti-slip step design, which makes it easy for operators to safely go up and down the support platform 1 when working on the water. Whether it is equipment maintenance, parameter debugging or material handling, it can provide a convenient passage and greatly improve the convenience of operation.

[0032] Meanwhile, a winch 304 is also installed on the upper surface of the support platform 1, providing more stable traction and adapting to different load requirements. A cable 305 is installed on one side of the winch 304, running through the support platform 1. The cable 305 is made of high-strength wear-resistant steel wire rope, possessing excellent tensile strength and corrosion resistance, and can withstand long-term use in humid aquatic environments. A mounting frame 306 is fixedly connected to the outer bottom end of the cable 305. The mounting frame 306 adopts a rigid frame structure and can be used to mount underwater mapping sensors, sampling equipment, and other auxiliary components. Through the winding and unwinding actions of the winch 304, the underwater depth of the mounting frame 306 can be precisely controlled, enabling mapping operations or sample collection at different water depths.

[0033] Working principle: The user can move the device to a designated location. The user can then adjust the length of the support legs 3 to support the device. At this point, two sets of auxiliary platforms 2 float on the sea surface, simultaneously supporting the device. The two sets of auxiliary platforms 2 are symmetrically arranged on both sides of the support platform 1. When the sea impacts the auxiliary platforms 2, the auxiliary platforms 2 move. As the auxiliary platforms 2 move in different directions, they cause the first slider 202 and the second slider 206 to move on one side of the first slide rail 201 and the second slide rail 205, respectively. This movement stretches the connecting rod 203 and compresses the spring 209, storing elastic potential energy. Simultaneously, the spring 209, symmetrically arranged on the other side, is stretched and stores elastic potential energy, thus offsetting some of the impact force of the waves. This is achieved through the hydraulic buffer cylinder. The compression and buffering of 208 can also offset some of the impact force. The bilge fin 211 is fixed, which greatly increases the roll damping and effectively suppresses the lateral sway of the platform. The tail stabilizing fin 210 is retractable, and its fin angle can be adjusted by a simple mechanical linkage mechanism. By adjusting the angle difference between the left and right tail fins, a torque that resists the impact of the lateral water flow can be generated, enhancing the course stability. When approaching the shore, the device can be supported by the support frame 302. The ladder 303 makes it easy for workers to climb onto the inner side of the support platform 1. The winch 304 can drive the cable 305 to adjust the height of the mounting frame 306. The mounting frame 306 has multiple standardized quick-installation interfaces with angle scales, which can be used to install various sensors such as depth sounders, side-scan sonar, ADCP, and underwater cameras.

[0034] The surveying equipment used in this project is highly stable, adaptable, and easy to operate, ensuring high accuracy in surveying operations under complex water conditions. Through the length adjustment of the support legs 3 and the symmetrical support of the two auxiliary platforms 2, device positioning and level calibration can be completed quickly. When the auxiliary platform 2 is impacted by waves, it drives the first slider 202 and the second slider 206 to move along the first slide rail 201 and the second slide rail 205. Combined with the elastic potential energy storage of the spring 209 and the buffering effect of the hydraulic buffer cylinder 208, the impact force of the waves can be effectively offset. Simultaneously, the fixed bilge fin 211 increases roll damping. The retractable tail stabilizing fin 210 generates anti-water flow torque through angle adjustment, greatly improving the device's anti-sway and heading stability in wind and waves, ensuring the accuracy of sensor mapping data; the support frame 302 facilitates the device's support on shore, the ladder 303 facilitates personnel access to the support platform 1, and the winch 304 drives the cable 305 to flexibly adjust the height of the mounting frame 306. Its pre-set standardized quick-install interface with angle scale can quickly adapt to various mapping sensors such as depth sounders and side-scan sonars, meeting diverse mapping needs without additional modification, significantly improving work efficiency and equipment versatility.

[0035] The above are merely preferred embodiments of the present invention and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments that can be applied to other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
