Description

Technical Field

[0001] This invention relates to the field of lock technology, specifically to a three-stage water-saving lock structure and its construction method. Background Technology

[0002] A lock is a type of "navigation structure" that allows ships to navigate at different water levels. Existing lock hydraulic structures are all made of concrete. The upper and lower lock heads are generally dock-type structures, and the lock chamber can be either dock-type or separate. Water-saving gate valves achieve water-saving control through a water-saving pool structure in conjunction with the water conveyance corridor.

[0003] Chinese Patent Publication No. CN219470874U, published on August 4, 2023, discloses a water-saving pool structure and a water-saving lock. The water-saving pool structure includes multiple water-saving pools for water storage. Some of the water-saving pools are horizontally offset relative to another portion, and some are also vertically offset relative to another portion. This water-saving pool structure solves the problem of inconvenience in using existing water-saving pool structures. Chinese Patent Publication No. CN110424360B, published on November 8, 2019, discloses an all-steel structure water-saving lock, which consists of an upper lock head, a lower lock head, and a lock chamber made of steel. The lock chamber comprises several... Composed of several independent structural sections, each including a base plate and a gate wall, the gate wall contains multiple water storage tanks arranged in layers. Each tank has an inlet / outlet port for easy water flow, and these ports connect to the interior of the gate chamber through the gate wall. A working valve is installed at each inlet to open / close it. The upper and lower gate heads are located upstream and downstream of the gate chamber, respectively, and both are equipped with water conveyance channels that connect to the interior of the gate chamber. This all-steel structure water-saving lock can shorten the construction period, eliminate concrete residue to reduce pollutant generation, save water, reduce the working head, and shorten the filling and emptying time of the gate chamber, thereby effectively improving the lock's throughput capacity.

[0004] In the current operation of the water-saving lock, although its lock chamber water filling mechanism has achieved water conservation to a certain extent, in actual operation, the lock chamber water filling is mainly carried out through the bottom. When the bottom is blocked by the accumulation of impurities, this situation will not only prolong the filling and emptying time of the lock chamber and reduce the operating efficiency of the lock, but the accumulation of impurities may also block the valve body, thereby affecting the normal closing of the valve body and reducing the safety and reliability of the lock.

[0015] Compared with the prior art, the beneficial effects of the present invention are: 1.

The filter frame 13 is located on the left and right sides of the valve body 10 and the filter frame 13 and the water guide chamber 11 are detachably connected.

[0020] A construction method for a three-stage water-saving ship lock structure, comprising the following steps: Step 1: Level the site, set up temporary facilities, conduct surveying and layout to determine the location and elevation of each part of the lock, ensure water and electricity connections and road paving to ensure smooth construction and transportation, and then carry out foundation excavation and foundation reinforcement.

[0021] Step 2: Tie the reinforcing bars of the base plate 1 and the pier 2, set up the formwork, pour the concrete, vibrate and compact it and cure it. During the construction of the base plate 1, the corridor structure 8 is pre-embedded. The gate installation groove and related pre-embedded parts are reserved on the gate pier to ensure accurate gate installation. Before pouring the base plate 1, the water guide chamber 11 is pre-embedded below the valve body 10 so that it forms an integral structure with the base plate 1 after the pouring is completed.

[0022] Step 3: After the concrete reaches the required strength, install the gate body 9 and valve body 10. Use hoisting equipment to smoothly hoist the gate body 9 and valve body 10 into the gate slot. Adjust the verticality and center position of the gate body 9. Then install the hoist and fix it on the pre-embedded foundation. Debug the hoist's stroke, opening and other parameters to ensure that the hoist runs smoothly and the gate opens and closes flexibly. After the valve body 10 and gate body 9 are installed, install the filter frame 13 to provide filtration for the water passing through the guide chamber 11.

[0023] Example 2: Based on Example 1, as follows Figure 4-8 As shown, a locking member 12 is fixed to the outside of the water guiding chamber 11.

The docking block 15 is fixed below the mounting frame 14. The docking block 15 and the water guiding chamber... The bottom of 11 has a concave-convex fit connection. The limiting head 16 is set inside the docking block 15 and between the docking block 15 to form a telescopic structure. The outer end of the limiting head 16 has an inclined structure design. The limiting groove 17 is opened inside the water guiding chamber 11. The limiting groove 17 and the limiting head 16 form a locking structure. The first elastic member 18 is fixedly connected to the limiting head 16 to provide thrust to the limiting head 16. The first control rope 19 is connected to the limiting head 16 to control the movement of the limiting head 16. The control head 20 is connected to the first control rope 19 and is located above the mounting frame 14.

[0024] The water passing through the water guiding chamber 11 is filtered by the filter frame 13 to prevent impurities from accumulating below the valve body 10. The filter frame 13 is installed inside the water guiding chamber 11 via the mounting frame 14. The bottom of the mounting frame 14 can also collect impurities. When the filter frame 13 needs to be cleaned and maintained, it can be connected to the lifting mechanism and the control head 20. Then, the control head 20 is pulled, causing it to move the limit head 16 via the first control rope 19. Figure 8 As shown, by disconnecting the limiting head 16 and the limiting groove 17, the mounting frame 14 and the filter frame 13 can be removed from the inside of the water guiding chamber 11.

[0025] Example 3: Based on Example 2, such as Figure 9-11 As shown, a rotating actuating wheel 21 is further disclosed inside the mounting frame 14. Water flows through the water guide chamber 11, causing the actuating wheel 21 to rotate. A self-cleaning structure is provided above the filter frame 13. The self-cleaning mechanism includes a cleaning plate 22, a mounting base 23, a drive block 24, a second control rope 25, a winding shaft 26, a torsion spring 27, and a pulling mechanism. The cleaning plate 22 is disposed on the upper surface of the filter frame 13. The mounting base 23 is fixed above the filter frame 13 and is located at the end of the cleaning plate 22. The drive block 24 is fixed at the end of the cleaning plate 22, and a sliding connection is formed between the drive block 24 and the mounting base 23. The second control rope 25 is fixed to the surface of the drive block 24. A take-up shaft 26 is rotatably mounted inside the mounting base 23 and is connected to a second control rope 25, which is wound around the surface of the take-up shaft 26. A torsion spring 27 is connected to the take-up shaft 26 to provide rotational return force for the take-up shaft 26. A pulling mechanism is disposed opposite to the take-up shaft 26 and provides moving pulling force for the drive block 24. The pulling mechanism includes a third control rope 28, a control shaft 29, a transmission shaft 30, a linkage shaft 31, an output shaft 32, and a power cutting mechanism. The third control rope 28 is fixedly connected to the drive block 24. The control shaft 29 is rotatably mounted inside the mounting base 23 and is connected to the third control rope 28. The transmission shaft 30 passes through the control rope 28. Shaft 29, drive shaft 30, and mounting frame 14 form a rotatable connection. Linkage shaft 31 is perpendicular to drive shaft 30 and meshes with drive shaft 30 via bevel gears. Output shaft 32 is fixedly connected to actuating wheel 21 and connected to linkage shaft 31 via bevel gears. A power cutting mechanism is positioned above drive shaft 30 to control the power transmission between drive shaft 30 and control shaft 29. The power cutting mechanism includes connecting block 33, connecting groove 34, second elastic element 35, fourth control rope 36, moving block 37, linkage plate 38, and top block 39. Connecting block 33 is positioned inside drive shaft 30 and forms a telescopic structure with drive shaft 30. Connecting groove 35... 4. Inside the control shaft 29, the connecting groove 34 and the connecting block 33 form an engaging structure. The second elastic element 35 is connected to the connecting block 33 to provide thrust to the connecting block 33. The fourth control rope 36 is fixedly connected to the connecting block 33. The moving block 37 is set above the transmission shaft 30 and forms an up-and-down sliding structure between the transmission shaft 30 and the transmission shaft 30. The moving block 37 is fixedly connected to the fourth control rope 36. The linkage plate 38 is set above the moving block 37. The upper end of the moving block 37 and the linkage plate 38 form a rotatable connection. The top block 39 is fixed below the linkage plate 38. The lower end of the top block 39 has an inclined structure design, and the top block 39 is located in the moving direction of the drive block 24.

[0026] The first control rope 19, the second control rope 25, the third control rope 28, and the fourth control rope 36 can be made of steel wire rope, and the elastic element can be a waterproof spring with high elasticity to ensure stable operation of the structure.

[0027] When the valve body 10 is open, water flows through the inside of the guide chamber 11, driving the actuating wheel 21 to rotate. As the actuating wheel 21 rotates, it drives the linkage shaft 31 via the output shaft 32 and bevel gear. The linkage shaft 31 then drives the transmission shaft 30 to rotate via the bevel gear. Figure 10 As shown, the drive shaft 30 drives the control shaft 29 to rotate. The control shaft 29 winds up the third control rope 28, causing it to pull the drive block 24 and move the cleaning plate 22. At the same time, the second control rope 25 unwinds on the surface of the winding shaft 26, causing the cleaning plate 22 to move and clean the surface of the filter frame 13. When the drive block 24 moves to the maximum moving position, as shown... Figure 11 As shown, the drive block 24 moves the pressing top block 39 upward, and the top block 39 drives the moving block 37 to move through the linkage plate 38. The moving block 37 pulls the connecting block 33 to move through the fourth control rope 36, releasing the movement of the connecting block 33 and the connecting groove 34, so that the transmission shaft 30 continues to rotate but does not drive the control shaft 29 to rotate, so that after the drive block 24 moves to the maximum position, the actuating wheel 21 can still rotate continuously.
