Description

Technical Field

[0001] This utility model relates to the field of lock head technology, specifically to a lock head built into the lock machine room. Background Technology

[0002] A ship lock is a navigation structure that allows ships to overcome concentrated water level differences. It offers high cargo throughput and is widely used in water conservancy and water transport engineering. The main structure of a ship lock consists of upper and lower lock heads, lock chambers, a water conveyance system, a navigation channel, navigation structures, berthing structures, lock valves, opening and closing machinery, electrical control equipment, and an information system. When a ship is traveling upstream, the downstream water valves are controlled to drain water from the lock chamber to the downstream level, opening the lower working gate and allowing the ship to enter the lock chamber from the downstream. When the lower working gate is closed, the upstream water valves are controlled to pump water into the lock chamber from the upstream to the upstream level, opening the upper working gate and allowing the ship to leave the lock chamber and enter the upstream channel. The process is reversed for downstream ships.

[0003] To control water level rise and fall and allow ships to pass through the lock, a series of gate valves, their opening and closing mechanisms, and electrical control equipment need to be installed inside the lock head. To ensure the safe and reliable operation of the opening and closing mechanisms, a separate machine room needs to be built above the lock head to house the opening and closing mechanisms and electrical control equipment. The machine room needs to be constructed by a specialized construction team after the hydraulic lock head structure is poured, resulting in a long construction period, multiple professional categories, and complex construction. Furthermore, since the machine room is located above the lock head piers, the equipment and facilities inside must be moved out using forklifts or other mobile devices, or lifted using permanently fixed lifting equipment within the machine room. Small-scale maintenance can usually be accommodated; however, when large structures such as valves or gate hoists need to be moved out of the machine room for major repairs, relocation is inconvenient, and large lifting equipment such as cranes lacks the necessary lifting environment.

[0004] In summary, there is an urgent need for a lock head integrated into the lock machine room to solve or at least partially solve the problems existing in the prior art. Utility Model Content

[0005] The purpose of this utility model is to provide a lock head integrated into the lock machine room, which aims to solve the technical problem of inconvenience in hoisting equipment in the machine room during the maintenance of existing opening and closing facilities. The specific technical solution is as follows:

[0006] A lock head with an internal control room includes a side pier and a waterproof cover. The side pier contains a water conveyance corridor, a gate control room, and a valve well.

The winch is installed on the top of the opening and closing machine room, and the first valve is movably arranged in the water conveyance channel along the height direction to open and close the water conveyance channel; the winch is connected to the top of the first valve.

[0013] Furthermore, an installation groove is provided on the side pier, which is located at the first lifting hole. The winch is an inverted winch, which is fixedly connected in the installation groove.

[0014] Furthermore, the second opening and closing mechanism includes a linear drive assembly, connecting rods, and a second valve. The linear drive assembly is installed in the opening and closing machine room. Multiple connecting rods are arranged along the height direction and connected end to end in sequence. The upper end of the top connecting rod is connected to the linear drive assembly, and the lower end of the bottom connecting rod is connected to the second valve. The length of each connecting rod is less than the working stroke of the linear drive assembly.

[0015] Preferably, the second opening and closing mechanism is arranged below the second lifting hole, and the second opening and closing mechanism is completely arranged in the opening and closing machine room; the linear drive component is a hydraulic cylinder or an electric push rod.

[0016] Furthermore, a guide groove is also provided inside the side pier. The guide groove is arranged on the side wall of the valve well. A roller is provided on the second valve. The roller is rotatably connected to the second valve and is arranged in the guide groove.

[0029] To facilitate understanding of this invention, a more comprehensive description is provided below, along with preferred embodiments. However, this invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this invention.

[0030] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0031] Example:

[0032] See Figures 1-3 This embodiment provides a lock head with a built-in lock machine room, including a side pier 1 and a waterproof cover plate 2. The side pier 1 is provided with a water conveyance corridor 11, a gate opening and closing machine room 12 and a valve well 13. The water conveyance corridor 11 is located at the bottom of the side pier 1, the gate opening and closing machine room 12 is arranged at the top of the side pier 1, and the valve well 13 is arranged in the side pier 1 along the height direction. The top of the valve well 13 is connected to the gate opening and closing machine room 12, and the bottom of the valve well 13 is connected to the water conveyance corridor 11. An inspection port 14 is provided at the top of the side pier 1, and the waterproof cover plate 2 is arranged to cover the inspection port 14. The top of the side pier 1 is flush with the ground.

[0033] Research revealed that existing gate hoist rooms are ground-level structures, typically two stories high. The ground floor houses the gate hoists and other mechanical components, while the second floor contains control equipment such as electrical control cabinets. However, during maintenance of the existing gate hoist rooms, the roof is enclosed, and the hoists are installed on the ground floor, making it impossible to use hoisting equipment to lift them through the roof. Even with an access panel (14) in the roof, the height of the roof itself prevents cranes from lifting the equipment. Forklifts or manual hoists are required for movement and transport, which is inconvenient. Furthermore, existing designs and construction require collaboration between building and hydraulic engineers, resulting in a large workload, long construction period, and high operating costs.

[0034] It is understood that through the aforementioned structural improvements, the gate hoist room 12 is directly arranged within the side pier 1, with its roof flush with the ground. This arrangement eliminates the need for building structure design, thus removing the need for building architects. Hydraulic engineers can directly complete the design, improving its overall integrity and saving significant time by eliminating the need for collaborative design. Secondly, this arrangement eliminates the need for a separate gate hoist room 12 on the ground, greatly reducing construction costs. Furthermore, this arrangement allows for easy maintenance of equipment such as the gate hoist in the gate hoist room 12. The waterproof cover 2 can be opened, and hoisting equipment can be easily lifted out for maintenance. Because the top of the side pier 1 is flush with the ground, hoisting equipment can conveniently lift the equipment in the gate hoist room 12 through the maintenance opening 14 after opening the waterproof cover 2.

[0035] Furthermore, a maintenance platform 15 is installed inside the valve well 13, and the elevation of the maintenance platform 15 is higher than the navigation water level.

[0036] It can be understood that, through the setting of the maintenance platform 15, when the equipment in the valve well 13 is damaged, the damaged equipment in the valve well 13 can be moved to the maintenance platform 15, making it convenient to repair the damaged equipment in the valve well 13.

[0037] Furthermore, a settling groove is installed at inspection port 14 to ensure that the top surface of the waterproof cover plate 2 is flush with the top surface of the side pier 1. This arrangement ensures that the top surface of the side pier 1 is completely flat after construction, making it less likely for operators to trip over the protruding waterproof cover plate 2 when walking on the top surface of the side pier 1. In addition, the waterproof cover plate 2 will not obstruct the transport of items by trolley, making it more convenient to transport items.

[0038] Furthermore, three inspection ports 14 are provided: a first lifting hole 141 corresponding to the first opening and closing mechanism 3, a second lifting hole 142 corresponding to the second opening and closing mechanism 4, and a third lifting hole 143 corresponding to the pump station in the opening and closing machine room 12; three waterproof covers 2 are also provided corresponding to the inspection ports 14. Specifically, the first lifting hole 141 facilitates the installation and maintenance of the first opening and closing mechanism 3; the second lifting hole 142 facilitates the installation and maintenance of the second opening and closing mechanism 4; and the third lifting hole 143 facilitates the disassembly, assembly, and maintenance of accessories such as the power distribution cabinet and pump station in the opening and closing machine room 12. The waterproof covers 2 are electrically operated, which can reduce the labor intensity of operators.

[0039] Furthermore, multiple cavities 17 are provided within the side pier 1, and these cavities 17 are arranged at intervals within the side pier 1. It should be noted that the side pier 1 is entirely constructed of cast concrete. By rationally setting the cavities 17 within the side pier 1, a significant amount of concrete is saved while ensuring the overall strength of the side pier 1, thus greatly reducing construction costs.

[0040] Furthermore, it also includes a first opening and closing mechanism 3 and a second opening and closing mechanism 4; two valve wells 13 are provided, and the first opening and closing mechanism 3 and the second opening and closing mechanism 4 are respectively arranged in the two valve wells 13, and the first opening and closing mechanism 3 is located at the upstream end of the second opening and closing mechanism 4.

[0041] It is known that the water conveyance corridor 11 is controlled by the first and second gate openers.

[0042] Furthermore, the first opening and closing mechanism 3 includes a winch 31 and a first valve 32. The winch 31 is installed on the top of the opening and closing machine room 12, and the first valve 32 is movably arranged in the water conveyance corridor 11 along the height direction to open and close the water conveyance corridor 11; the winch 31 is connected to the top of the first valve 32.

[0043] It is known that the first valve 32 is controlled by the winch 31. When the first valve 32 needs to be opened, the winch 31 rewinds and pulls the first valve 32 upward. The first valve 32 moves upward along the valve well 13, thereby opening the water conveyance channel 11. When the first valve 32 needs to be closed, the winch 31 unwinds and lowers the first valve 32. Under the action of gravity, the first valve 32 moves downward along the valve well 13 until the water conveyance channel 11 is closed.

[0044] Furthermore, an installation groove 18 is provided on the side pier 1, which is located at the first lifting hole 141. The winch 31 is an inverted winch, which is fixedly connected in the installation groove 18. With this arrangement, the winch 31 can be completely installed below the first inspection port 14, preventing the winch 31 from protruding from the first inspection port 14 and affecting the installation of the waterproof cover 2.

[0045] Furthermore, the second opening and closing mechanism 4 includes a linear drive assembly 41, a connecting rod 42, and a second valve 43. The linear drive assembly 41 is installed in the opening and closing machine room 12. Multiple connecting rods 42 are arranged along the height direction and connected end to end in sequence. The upper end of the top connecting rod 42 is connected to the linear drive assembly 41, and the lower end of the bottom connecting rod 42 is connected to the second valve 43. The length of each connecting rod 42 is less than the working stroke of the linear drive assembly 41.

[0046] Specifically, a linear drive mechanism drives the connecting rod 42 to move up and down, thereby moving the second valve 43 up and down to open or close it. When maintenance of the second valve 43 is required, the linear drive mechanism drives the connecting rod 42 to move upward, locking the lower connecting rod 42 at the maintenance platform 15 after each movement of the connecting rod 42 length, and removing the upper connecting rod 42 of the maintenance platform 15. The linear drive mechanism then moves downward, hinges with the lower connecting rod 42 of the maintenance platform 15, unlocks the lower connecting rod 42, and continues to move upward. This process is repeated, removing the connecting rods 42 one by one until the second valve 43 is moved to the maintenance platform 15 for maintenance. After maintenance of the second valve 43 is completed, the connecting rods 42 are reconnected one by one in the reverse operation to reset the second valve 43. It is understood that, through the design of the above structure, the second valve 43 can be easily opened and closed, and the second valve 43 can be easily moved to the maintenance platform 15 for maintenance.

[0047] In a preferred embodiment, the second opening and closing mechanism 4 is arranged below the second lifting hole 142, and the second opening and closing mechanism 4 is completely arranged inside the opening and closing machine room 12; the linear drive assembly 41 can also be a hydraulic cylinder, the first end of which is fixed to the housing, and the driving end of which is hinged to the connecting rod 42. By extending or retracting the hydraulic cylinder, the connecting rod 42 is driven to move up and down, thereby driving the second valve 43 to move up and down to open or close the water conveyance corridor 11. Of course, in some other embodiments of this application, the linear drive assembly 41 can also be an electric push rod or other components or structures capable of driving the connecting rod 42 to move up and down.

[0048] It should also be noted that the second gate opener, which uses a hydraulic cylinder, is located downstream of the first gate opener, which uses a winch 31. The water level in the water conveyance channel 11 opened and closed by the first gate opener is shallow and has low resistance, while the water level in the water conveyance channel 11 opened and closed by the second gate opener is deep and has high resistance. The winch 31 has a small opening and closing force and is inexpensive, while the hydraulic cylinder and connecting rod 42 can provide a greater opening and closing force, but the cost is relatively high. Through the integrated arrangement of the winch 31 and the hydraulic cylinder, the stable opening and closing of the first valve 32 and the second valve 43 can be guaranteed, while the overall cost can be reduced and the economy can be improved.

[0049] Furthermore, a guide groove 16 is also provided inside the side pier 1. The guide groove 16 is arranged on the side wall of the valve well 13. A roller 431 is provided on the second valve 43. The roller 431 is rotatably connected to the second valve 43 and is rolled in the guide groove 16. Two guide grooves 16 are arranged symmetrically on both sides of the valve well 13. The width of the guide groove 16 is slightly larger than the diameter of the guide wheel, so that there is a clearance fit between the guide groove 16 and the guide wheel to prevent the guide wheel and the guide groove 16 from getting stuck.

[0050] It is understood that, through the setting of guide groove 16 and roller 431, the guide groove 16 guides the guide roller during the up and down movement of the second valve 43, thereby guiding the second valve 43 and preventing the second valve 43 from hitting the well wall of valve well 13 and causing damage to the rubber seal on the second valve 43, thus causing damage to the second valve 43.

[0051] Furthermore, it also includes a ladder 5, which is installed inside the valve well 13; the ladder 5 is arranged along the height direction of the valve well 13, and the top of the ladder 5 extends upward into the gate opening and closing room 12, and the bottom of the ladder 5 extends downward into the maintenance platform 15.

[0052] It is known that operators can easily access the maintenance platform 15 of the valve well 13 from the gate control room 12 via ladder 5 to inspect and maintain the equipment in the valve well 13.

[0053] Furthermore, the ladder 5 is detachably connected to the side wall of the valve well 13, and the ladder 5 is made of welded steel pipes. Specifically, by using welded steel pipes, the connection is secure through welding, and the hollow steel pipes greatly reduce the overall weight of the ladder 5. This ensures structural strength while facilitating installation, saving materials and reducing costs.

[0054] It should be noted that in some other embodiments, the ladder 5 may also be a rope ladder or other structure or component that facilitates operators to enter the maintenance platform 15 from the gate room 12.

[0055] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
