[0012] As a preferred technical solution, the winch includes a second motor installed on one side of the outer surface of the bracket. The output shaft of the second motor movably passes through the inner cavity of the bracket and is fixedly connected to a wire roller. A guide wheel is installed on the top of the inner cavity of the bracket. A suspension wire is wound on the surface of the wire roller. One end of the suspension wire is fixedly connected to the wire roller, and the other end of the suspension wire passes through the guide wheel and is fixedly connected to the lifting ring of the housing.

[0017] This utility model has at least the following beneficial effects:

[0018] This application utilizes a method where a support mechanism is installed at a desired location (e.g., on a dredging vessel). A winch lowers the measuring and guiding mechanisms as a whole until the bottom of the guiding mechanism contacts the silt surface. A drive mechanism then manipulates a screw and a plunger to move downwards, gradually inserting the plunger into the silt. The increased friction when the plunger contacts the silt increases the drive current, allowing the current detection module to effectively determine the plunger's current position within the silt. During dredging, the silt spreads, reducing friction and decreasing the drive current. The current detection module then determines the plunger is no longer inside the silt, thus providing a clear indication of the silt diffusion process and making dredging measurements more convenient and efficient.

Detailed Implementation

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-3An embodiment of this utility model provides a dredging measurement device, including: a support mechanism 100, a measuring mechanism 200 for dredging measurement, a winch 300 for driving the measuring mechanism 200 to move up and down, and a guide mechanism 400 for guiding the measuring mechanism 200. The measuring mechanism 200, the winch 300, and the guide mechanism 400 are all located in the inner cavity of the support mechanism 100. The measuring mechanism 200 includes a housing 210 located in the inner cavity of the support mechanism 100. The housing 210 is located at the top of the guide mechanism 400. A screw 220 is movably passed through the housing 210. The bottom end of the screw 220 extends into the interior of the guide mechanism 400 and is fixedly connected to a rod 230. The inner cavity of the housing 210 is provided with a driving member 240 for driving the screw 220 to move up and down. The inner cavity of the housing 210 is also equipped with a current detection module 250 that works in conjunction with the driving member 240.

[0025] It should be noted that the aforementioned current detection module 250 can adopt a current detection module disclosed in the existing announcement number CN221261092U, which has the advantages of low heat generation and high accuracy. It can not only send the current value to the CAN network, but also display it on the OLED display screen, which is intuitive and convenient. It is existing technology, so it will not be described in detail in this technical solution.

[0026] The support mechanism 100 includes a bracket 110, with a support plate 120 fixedly connected to the bottom of the bracket 110. The housing 210 is located in the inner cavity of the bracket 110, the winch 300 is located in the inner cavity of the bracket 110, and the guide mechanism 400 is located between the support plate 120 and the housing 210. The support mechanism 100 can provide an installation foundation for the measuring mechanism 200, the winch 300, and the guide mechanism 400. The top of the bracket 110 is provided with a clearance groove 111 that is compatible with the screw 220. The clearance groove 111 can provide clearance for the screw 220, preventing the bracket 110 from obstructing the lifting and lowering of the screw 220.

[0027] The driving component 240 includes a threaded sleeve 241 that is threaded onto the surface of the screw 220. The outer surface of the threaded sleeve 241 is rotatably connected to the housing 210 through a bearing. A toothed ring 242 is fixedly connected to the lower part of the surface of the threaded sleeve 241. A first motor 243 is installed in the inner cavity of the housing 210. A gear 244 that meshes with the toothed ring 242 is fixedly connected to the output end of the first motor 243. The current detection module 250 is electrically connected to the first motor 243. By starting the first motor 243, the output shaft of the first motor 243 can drive the threaded sleeve 241 to rotate. Under the action of the thread, the screw 220 can be driven to perform lifting and lowering operations on the housing 210, so that the screw 220 can drive the insertion rod 230 to gradually insert into the silt for measurement.

[0028] The winch 300 includes a second motor 310 mounted on one side of the outer surface of the bracket 110. The output shaft of the second motor 310 extends movably through the inner cavity of the bracket 110 and is fixedly connected to a wire roller 320. A guide wheel 330 is mounted on the top of the inner cavity of the bracket 110. A suspension wire 340 is wound around the surface of the wire roller 320. One end of the suspension wire 340 is fixedly connected to the wire roller 320, and the other end of the suspension wire 340 passes through the guide wheel 330 and is fixedly connected to the lifting ring of the housing 210. By starting the second motor 310, the wire roller 320 can be driven to rotate, so as to realize the winding or unwinding operation of the suspension wire 340, thereby achieving the lifting operation of the measuring mechanism 200.

[0029] Among them, two guide wheels 330 are symmetrically arranged at the top of the inner cavity of the bracket 110, and two suspension lines 340 are wound on both sides of the surface of the roller 320 to ensure the stability of the housing 210 when suspended and to avoid the phenomenon of deviation.

[0030] Each of the two sides of the surface of the roller 320 is fixedly connected with a set of retaining rings 350. Each set of retaining rings 350 is set one-to-one with each suspension line 340. There are two retaining rings 350 in each set, and the two retaining rings 350 are located on the side of the corresponding suspension line 340. The retaining rings 350 can limit the suspension line 340 to ensure the neatness of the suspension line 340 when it is wound up and unwound.

[0031] The guiding mechanism 400 includes a guide tube 410 fixedly connected to the bottom of the housing 210. The bottom end of the guide tube 410 extends movably through the bottom of the support plate 120 and is fixedly connected to the base 420. The bottom end of the screw 220 and the insertion rod 230 are both located in the inner cavity of the guide tube 410. The bottom end of the insertion rod 230 extends through the inner cavity of the base 420. A limiting member is provided between the bottom end of the screw 220 and the guide tube 410. When the winch 300 drives the measuring mechanism 200 to rise and fall, it can drive the guiding mechanism 400 to move synchronously, so that the guide tube 410 can slide at the through point of the support plate 120. This can prevent the measuring mechanism 200 from shaking when it moves up and down, and help improve the measurement effect of the measuring mechanism 200.

[0032] The limiting component includes a groove 430 formed in the inner cavity of the guide tube 410. A slider 440 is slidably connected to the inner cavity of the groove 430. The slider 440 is fixedly connected to the bottom end of the surface of the screw 220. When the driving component 240 drives the screw 220 to rise and fall on the housing 210, the screw 220 can drive the slider 440 to slide in the inner cavity of the groove 430, thereby preventing the screw 220 from rotating synchronously with the screw sleeve 241, so as to ensure the stability of the screw 220 when it rises and falls.

[0033] It should also be noted that both the first motor 243 and the second motor 310 mentioned above are stepper motors, which can realize the functions of stopping at any position and rotating in both directions.

[0034] The working principle of this utility model is as follows: The support plate 120 is installed in the required position, such as on a dredging vessel. The second motor 310 is started, driving the wire roller 320 and the retaining ring 350 to rotate, thereby achieving the unwinding operation of the suspended wire 340. At this time, the measuring mechanism 200 and the guiding mechanism 400 move downwards under their own weight. The measuring mechanism 200 drives the end of the suspended wire 340 to move synchronously, and the guide tube 410 slides at the penetration point of the support plate 120 until the base 420 contacts the horizontal surface of the silt. Then, the first motor 243 is started. The output shaft of the first motor 243 drives the gear 244 to rotate, which in turn drives the gear ring 242 and the threaded sleeve 241 to rotate. Under the action of the thread, the threaded sleeve 241 drives the screw 220. As the screw 220 moves downwards, it drives the insertion rod 230 and the slider 440 to move synchronously. The slider 440 slides within the inner cavity of the groove 430, causing the insertion rod 230 to gradually insert into the silt. When the insertion rod 230 contacts the silt, it generates a certain resistance, and the increased friction causes the driving current of the drive component 240 to increase. The current detection module 250 then effectively determines that the insertion rod 230 is currently inside the silt. When the silt spreads during dredging, the friction between the insertion rod 230 and the silt decreases, causing the driving current of the drive component 240 to decrease. The current detection module 250 then effectively determines that the insertion rod 230 is no longer inside the silt. Therefore, the silt diffusion state can be intuitively expressed, making dredging measurement more convenient and faster.

[0035] All parts not described in this utility model are the same as or can be implemented using existing technology. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this utility model, the scope of which is defined by the appended claims and their equivalents.
