Description

Technical Field

[0001] The present invention relates to the technical field of water depth measurement, and in particular to a water depth measurement device and method for waterway maintenance of water transport engineering. Background Art

[0002] Channel maintenance in water transport engineering refers to the regular maintenance and upkeep of the channel to ensure safe navigation and good navigation conditions. The purpose of channel maintenance is to maintain the navigable depth, width and integrity of the buoy navigation system so that ships can pass safely and efficiently. Silt and sediment in the channel will lead to reduced water depth and narrowing of the channel, affecting the passage of ships. Regular dredging operations are carried out to remove silt and sediment in the channel and restore the navigable depth and width. For channels with insufficient water depth, dredging operations can be carried out to increase the water depth by excavation or blasting to meet the navigation needs of ships. The above maintenance requires measurement of the water depth of the channel.

[0003] In the prior art, most of the methods are to put a sonic transmitter into the water bottom, and the sonic transmitter transmits a signal from the water bottom to the sonic receiver to measure the water depth. However, the current echo sounder has a complex sounding environment. Some debris floating on the water surface and the sounder moves down quickly under the action of the counterweight and collides with the bottom rocks, which can easily cause damage to the echo sounder, affecting the efficiency and effect of water depth measurement.

[0019] The present invention also discloses a water depth measurement method for water transport engineering channel maintenance, including a water depth measurement device for water transport engineering channel maintenance, and further comprising the following steps:

[0020] S1: When performing water depth measurement for channel maintenance, the mounting plate is installed on the side of the ship, and then the counterweight seat is taken out from the placement slot. The counterweight seat sinks rapidly under its own gravity. During the sinking process, the counterweight seat exerts force on the sounding tape, causing the sounding tape to fall with the counterweight seat until the counterweight seat sinks to the bottom of the channel. At this time, the detection camera is controlled to work, and the detection camera records the scale line of the sounding tape placed on the guide rod at this time;

[0021] S2: Then control the movement of the ship to make it sail along the channel. During this period:

[0022] If the bottom of the lower channel is lower than the initial sinking position of the counterweight seat after the hull moves, the counterweight seat drives the sounding belt to continue to sink, and the scale line of the sounding belt at the guide rod changes, and the detection camera records the changed scale line;

[0023] If the bottom of the lower channel is higher than the initial sinking position of the counterweight seat after the hull moves, the counterweight seat no longer generates tension on the sounding tape, and the rotating rod is reset and rotated under the action of the winding spring, and the rotating rod drives the reel to reel in the sounding tape, and the scale line of the sounding tape at the guide rod changes, and the detection camera records the changed scale line;

[0024] S3: When the rotating rod rotates, it drives the driving gear to rotate, and the driving gear meshes with the driven gear on the outside of the rotating shaft. Since the driven gear is a one-way gear, the rotating rod can only drive the driving gear to reset and rotate, and the meshing of the driving gear and the driven gear will drive the rotating shaft to rotate;

[0025] When the rotating shaft rotates, it drives the first connecting plate to rotate, the first connecting plate drives the second connecting plate to move, the second connecting plate drives the moving rod to move back and forth in the cleaning box through the moving plate, and then the moving rod drives the piston plate to move back and forth in the cleaning box;

[0026] When the piston plate moves to the right, the space of the right cavity becomes smaller, and the right cavity sprays water on the rolled-up sounding tape through the U-shaped spray plate. The space of the left cavity becomes larger, and the left cavity draws air outside the cleaning box through the air intake pipe. A filter is set at the end of the air intake pipe to filter the air.

[0027] The rolled-up sounding tape contacts the water-absorbing sponge, and the water-absorbing sponge absorbs the water sprayed on the outside of the sounding tape;

[0028] When the piston plate moves to the left, the space of the right cavity becomes larger, and the right cavity extracts water in the channel through the liquid inlet pipe. A filter is set at the end of the liquid inlet pipe to filter impurities in the water. The space of the left cavity becomes smaller, and the left cavity blows on the surface of the sounding belt through the U-shaped jet plate to quickly dry the surface of the sounding belt;

[0029] The rolled-up sounding tape is removed from the dirt and air-dried before being moved to the guide rod, where the detection camera clearly records the changing scale lines.

[0030] S4: After the water depth measurement in the channel is completed, the staff turns the handle to drive the rotating rod to rotate, the rotating rod reels the sounding tape, and the counterweight seat moves up, and finally the counterweight seat is placed back in the placement slot.

[0031] Compared with the prior art, the present invention provides a water depth measurement device and method for waterway maintenance in water transport engineering, which has the following beneficial effects:

[0032] 1. The water depth measuring device and method for water transport engineering channel maintenance, by making the automatic winding seat cooperate with the counterweight seat, the depth measuring tape is automatically lowered or wound up when sailing with the hull, so that the scale line of the depth measuring tape at the guide mechanism changes, and the detection camera shoots and records the changed scale line, so as to achieve accurate measurement of the water depth in the channel and ensure the working efficiency of the water depth measurement.

[0033] 2. The depth measuring device and method used for waterway maintenance of water transport engineering projects, through the operation of the cleaning mechanism, enables the cleaning mechanism to rinse and dry the sounding tape removed from the water body, so that the sounding tape remains clean, ensures that the detection camera clearly records the scale lines on the sounding tape, improves the accuracy of the sounding result, and makes the rolled-up sounding tape tidy.

[0034] 3. The depth measuring device and method for waterway maintenance of water transport engineering, by setting the driven gear as a one-way gear, makes the rotating rod drive the driving gear to reset and rotate only when the meshing of the driving gear and the driven gear drives the rotating shaft to rotate, thereby avoiding that the cleaning mechanism is driven to work when the rotating rod rotates forward or reverse, resulting in an increased probability of damage to the cleaning mechanism, thereby ensuring the service life of the depth measuring device.

[0035] 4. The water depth measuring device and method for waterway maintenance of water transport engineering, when the rotating shaft rotates, the active bevel gear and the driven bevel gear on the transmission rod are meshed and transmitted, the driven bevel gear drives the transmission rod and the reciprocating screw at the end of the transmission rod to rotate, the sleeves on the two reciprocating screws respectively drive the movable plate to move, when the two movable plates are relatively close, the movable plate squeezes the water absorbent sponge to squeeze out the water in the water absorbent sponge, to avoid the water absorbent sponge being saturated with water and no longer absorbing moisture on the surface of the sounding belt, thereby ensuring the cleaning effect of the sounding belt.

During the sinking process of the counterweight seat 5, a force is exerted on the sounding tape 3, so that the sounding tape 3 falls with the counterweight seat 5, until the counterweight seat 5 sinks to the bottom of the channel. At this time, the detection camera 6 is controlled to work, and the detection camera 6 records the scale line 301 of the sounding tape 3 placed on the guide rod 403 at this time, and then the hull is controlled to move to make the hull sail along the channel.

[0067] The present invention also discloses a water depth measurement method for water transport engineering channel maintenance, comprising the aforementioned water depth measurement device for water transport engineering channel maintenance, and further comprising the following steps:

[0068] S1: When performing water depth measurement for channel maintenance, the mounting plate 1 is installed on the side of the ship by bolts, and then the counterweight seat 5 is taken out from the placement slot 101. The counterweight seat 5 sinks rapidly under its own gravity. During the sinking process, the counterweight seat 5 exerts a force on the sounding tape 3, so that the sounding tape 3 falls with the counterweight seat 5 until the counterweight seat 5 sinks to the bottom of the channel.

[0072] S3: When the rotating rod 202 rotates, the driving gear 2022 is driven to rotate, and the driving gear 2022 is meshed with the driven gear 801 on the outer side of the rotating shaft 8. Since the driven gear 801 is a one-way gear, the rotating rod 202 can only drive the driving gear 2022 to reset and rotate, and the meshing of the driving gear 2022 and the driven gear 801 will drive the rotating shaft 8 to rotate;

[0073] When the rotating shaft 8 rotates, the first connecting plate 802 is driven to rotate, and the first connecting plate 802 drives the second connecting plate 803 to move, and the second connecting plate 803 drives the moving rod 806 to move back and forth in the cleaning box 7 through the moving plate 805, and then the moving rod 806 drives the piston plate 701 to move back and forth in the cleaning box 7;

[0074] When the piston plate 701 moves to the right, the space of the right cavity 703 becomes smaller, and the right cavity 703 sprays water on the rolled-up sounding tape 3 through the U-shaped liquid spray plate 7032, and the space of the left cavity 702 becomes larger, and the left cavity 702 draws the external air of the cleaning box 7 through the air inlet pipe 7021, and a filter is set at the end of the air inlet pipe 7021 to filter the air;

The counterweight seat (5) sinks rapidly under the action of its own gravity. During the sinking process, the counterweight seat (5) exerts a force on the sounding belt (3), causing the sounding belt (3) to fall along with the counterweight seat (5), until the counterweight seat (5) sinks to the bottom of the channel.
