Description

Technical Field

[0001] This invention relates to the field of gate technology, and in particular to a modular gate structure that can be disassembled as a whole and its installation method. Background Technology

[0002] As a key control device in water conservancy projects, sluice gates are widely used in various hydraulic structures such as rivers, canals, reservoirs, and ports. Their core function is to achieve precise control of water level, flow rate, and flow direction through a movable water-retaining structure. With the rapid development of urban water conservancy infrastructure construction, higher requirements are placed on the operational reliability and ease of maintenance of sluice gate equipment.

[0003] Currently, existing gate structures typically employ an installation method where the base and concrete sidewalls are cast as a single unit. During construction, the gate base is initially positioned to the concrete structure using pre-embedded anchor bolts, followed by a secondary casting process to create a rigid integral structure between the base and the concrete sidewalls. The movable gate leaf is connected to the hoist via a screw rod. The hoist drives the screw rod to raise and lower the movable gate leaf along the base's sliding groove. During descent, the movable gate leaf relies on the impact force of the water flow to tightly adhere to the sealing copper strip on the base, thus achieving a watertight seal.

[0004] However, when the gate components of the aforementioned integrally cast structure are damaged due to long-term water flow impact and wear from debris in the water, the gate base is already cast into an inseparable whole with the concrete structure. Therefore, maintenance work can only be carried out through underwater operations or by stopping the water flow and draining the water. The former has the problems of complex working environment and high safety risks, while the latter has a large impact range and interferes with users' water use, making gate maintenance work extremely inconvenient. Therefore, this application proposes a modular gate structure that can be disassembled as a whole and its installation method. Summary of the Invention

[0005] The purpose of this invention is to address the problem in the prior art where gate components are damaged due to long-term water flow impact and wear from debris in the water. Since the gate base is cast as an inseparable whole with the concrete structure, maintenance work can only be carried out through underwater operations or water shut-off and drainage. The former has the problems of complex operating environment and high safety risks. The invention proposes a modular gate structure that can be disassembled as a whole and its installation method.

[0006] In a first aspect, the technical solution of the present invention is: a modular gate structure that can be disassembled as a whole, comprising a frame pre-embedded in concrete and a lifting plate installed on one side of the frame, and further comprising: A gate seat, the gate seat including a base plate and a gate base disposed on the base plate; A rubber soft seal is provided between the frame and the gate base. A strip groove is provided inside the frame on the side near the gate base, and a sealing copper strip is installed inside the strip groove. The movable door leaf has a valve mounting plate installed on the outer wall of the movable door leaf away from the frame, and an adjusting wedge is installed on the outer wall of the valve mounting plate away from the movable door leaf. A limit block is installed on one side of the outer wall of the gate base, and the adjusting wedge is slidably disposed inside the limit block. The disassembly and connection mechanism includes anchor bolts, which pass through the gate base, frame and rubber soft seal in sequence for fixing and tightening. The gate base and the base plate are fixedly connected by the anchor bolts. An L-shaped support plate is installed on one side of the outer wall of the base plate, and a pressing member is slidably arranged inside the L-shaped support plate. The top of the pressing member is installed at the bottom of the valve mounting plate.

[0007] Optionally, the valve body is installed in the middle of the valve mounting plate, and the movable door leaf is fitted with the sealing copper strip.

[0008] Optionally, the movable door leaf, valve mounting plate, and valve body are designed as an integrated unit.

[0009] Optionally, an L-shaped hanging plate is installed on the top of the valve mounting plate, and the top of the L-shaped hanging plate is mounted on the groove at the top of the movable door leaf.

[0010] Optionally, the inner inclined surface of the limiting block is slidably disposed with the inclined surface of one side of the outer wall of the adjusting wedge block.

[0011] Optionally, the gate structure may also include an opening and closing mechanism; The opening and closing mechanism includes a gate opener, which is located above the movable door leaf, and the output end of the gate opener is provided with a lead screw, one end of which is connected to the top of the valve mounting plate through an adapter.

[0012] Optionally, the frame is provided with mounting holes for connecting to the reinforcing bars.

[0013] Optionally, the gate base has an installation groove and a sliding groove for the movable gate leaf to slide inside, and the installation groove is located on the top of the gate base.

[0014] Optionally, the gate structure also includes a flow probe, which is disposed on one side of the outer wall of the gate base for real-time flow detection.

[0015] Secondly, the present invention provides a modular gate installation method that can be disassembled as a whole, applied to the modular gate structure that can be disassembled as a whole described in the first aspect, the method comprising the following steps: S1. The frame is hung on the reinforcing bars through the mounting holes, and concrete is poured so that the frame is embedded in the concrete. S2. Hoist the gate seat to the position corresponding to the frame, install a rubber soft seal between the frame and the gate seat, and use anchor bolts to pass through the gate seat and the rubber soft seal in sequence and fix them to the frame. At the same time, fix the gate seat to the base plate with the anchor bolts to compress the gate seat, the rubber soft seal and the frame, and install the movable door leaf on the gate seat so that the adjusting wedge block is slidably set inside the limit block. S3. When maintenance is required, remove the anchor bolts and lift the gate seat together with the movable gate leaf installed on it using the lifting plate, so that the gate seat is separated from the frame and the rubber soft seal.

[0016] Compared with the prior art, this application includes at least one of the following beneficial technical effects: This invention uses a frame embedded in concrete as an independent load-bearing foundation and fixes the gate seat to the frame with a detachable connector. When the gate component is damaged, the gate seat and the movable gate leaf can be lifted above the water surface for repair simply by disassembling the connector. This eliminates the need for underwater operations or water outages, significantly improving the convenience and safety of gate maintenance.

[0017] Furthermore, by setting up a double sealing interface with a rubber soft seal and a sealing copper strip, the rubber soft seal is always kept in a compressed state under the pressing action of the detachable connector. Combined with the inclined guiding action of the adjusting wedge and the limiting block when the movable door is closed, the movable door and the sealing copper strip are tightly fitted, achieving a stable and reliable water-stopping effect.

[0018] Finally, by installing a flow probe on the gate base, water flow data during the gate's operation can be collected and transmitted in real time. This, combined with a remote monitoring platform, enables intelligent monitoring and management of the gate's operating status, providing data support for water conservancy scheduling and giving the gate intelligent control functions.

[0021] The following specific examples illustrate the implementation of the present invention. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and various details in this specification can also be modified or changed based on different viewpoints and applications without departing from the spirit of the present invention. It should be noted that, unless otherwise specified, the following embodiments and features described therein can be combined with each other.

[0022] Example 1 like Figures 1-3 As shown, the present invention proposes a modular gate structure that can be disassembled as a whole, including a frame 17, a gate seat, a rubber soft seal 18, a movable gate leaf 6, a lifting plate 20 installed on one side of the frame 17, and a disassembly and connection mechanism; the gate seat includes a base plate 4 and a gate base 1 disposed on the base plate 4; the rubber soft seal 18 is disposed between the frame 17 and the gate base 1, and a strip groove 19 is provided inside the frame 17 on the side near the gate base 1, and a sealing copper strip 16 is installed inside the strip groove 19; a valve mounting plate 7 is installed on the outer wall of the movable gate leaf 6 away from the frame 17, and an adjusting wedge 11 is installed on the outer wall of the valve mounting plate 7 away from the movable gate leaf 6; a limit block 3 is installed on the outer wall of the gate base 1, and the adjusting wedge 11 is slidably disposed inside the limit block 3; The disassembly and connection mechanism includes anchor bolts 9, which pass through the gate base 1, frame 17 and rubber soft seal 18 in sequence for fixing and pressing. The gate base 1 and the base plate 4 are fixedly connected by anchor bolts 9. An L-shaped support plate 5 is installed on one side of the outer wall of the base plate 4, and a pressing member 10 is slidably arranged inside the L-shaped support plate 5. The top of the pressing member 10 is installed at the bottom of the valve mounting plate 7. In this embodiment, the valve body 8 is installed in the middle of the valve mounting plate 7, and the movable door 6 is fitted with the sealing copper strip 16; the movable door 6, the valve mounting plate 7, and the valve body 8 are designed as an integral part; an L-shaped hanging plate 12 is installed on the top of the valve mounting plate 7, and the top of the L-shaped hanging plate 12 is mounted on the groove at the top of the movable door 6; the inner inclined surface of the limiting block 3 slides against the inclined surface of one side of the outer wall of the adjusting wedge block 11. The disassembly and connection mechanism is described in detail below: In this embodiment, when the gate is in the closed state, the hoist 15 drives the movable gate leaf 6 to slide downward along the slide groove 22 of the gate base 1 via the lead screw 14. When the movable gate leaf 6 descends to near the bottom position, the adjusting wedge 11 set on one side of the outer wall of the valve mounting plate 7 gradually enters the inner side of the limiting block 3 set on one side of the outer wall of the gate base 1. Since the inner inclined surface of the limiting block 3 slides and engages with the inclined surface of the outer wall of the adjusting wedge 11, as the movable gate leaf 6 continues to descend, the adjusting wedge 11 generates horizontal displacement under the guidance of the inclined surface, thereby pushing the movable gate leaf 6 to move closer to the frame 17. At the same time, during the descent of the movable gate leaf 6, its bottom contacts the pressing member 10 inside the L-shaped support plate 5 set on one side of the outer wall of the base plate 4. The pressing member 10 generates elastic deformation under the pressure of the movable gate leaf 6, providing reverse support force for the movable gate leaf 6 and ensuring that the movable gate leaf 6 remains stable in the closed position.

[0023] When the movable gate leaf 6 reaches the fully closed position, it fits tightly against the sealing copper strip 16 installed in the groove 19 inside the frame 17, forming the first sealing interface. Simultaneously, the rubber soft seal 18 between the frame 17 and the gate base 1 remains compressed under the pressure of the anchor bolts 9, forming the second sealing interface. The two seals work together to ensure a reliable water-stopping effect when the gate is closed.

[0024] When a gate requires repair due to component damage during long-term use, underwater operations or water shut-off are unnecessary. Maintenance personnel simply need to remove the anchor bolts 9 to disconnect the gate base 1 from the frame 17. Then, using a lifting plate 20 connected to the frame 17, the gate base, along with the movable gate leaf 6, valve mounting plate 7, valve body 8, adjusting wedge 11, L-shaped hanging plate 12, and base plate 4, are lifted as a single module. During lifting, the L-shaped hanging plate 12, located on top of the valve mounting plate 7, is attached to the groove at the top of the movable gate leaf 6, ensuring that the movable gate leaf 6 and valve mounting plate 7 remain relatively fixed during lifting, preventing separation. After the entire module is lifted, the gate base is completely separated from the frame 17 and the rubber soft seal 18, allowing maintenance personnel to safely and conveniently complete the repair or replacement of gate components above the water surface. After repair, the entire gate module is reinstalled in its original position, and the anchor bolts 9 are installed to restore its functionality.

[0025] Example 2 like Figures 1-3 As shown, based on Embodiment 1, the modular gate structure also includes an opening and closing mechanism; the opening and closing mechanism includes an opening and closing machine 15, which is located above the movable gate leaf 6, and the output end of the opening and closing machine 15 is provided with a lead screw 14, one end of which is connected to the top of the valve mounting plate 7 through an adapter 13. The frame 17 is provided with mounting holes 21 for connecting to the reinforcing bars; the gate base 1 has an installation groove 2 and a sliding groove 22 for the movable gate leaf 6 to slide, and the installation groove 2 is located on the top of the gate base 1; the gate structure also includes a flow probe, which is located on one side of the outer wall of the gate base 1 for real-time flow detection. The modular gate structure is described in detail below: In this embodiment, when the gate is opened or closed, the hoist 15 starts and outputs rotational power to drive the lead screw 14 connected to its output end to rotate. The lead screw 14 is connected to the top of the valve mounting plate 7 through the adapter 13, converting the rotational motion into linear motion. Driven by the lead screw 14, the movable door leaf 6 moves up and down along the slide groove 22 opened inside the gate base 1.

[0026] When the gate needs to be opened, the hoist 15 drives the lead screw 14 to rotate forward. The lead screw 14, through the adapter 13, drives the valve mounting plate 7 and the movable gate leaf 6 to slide upward along the slide groove 22. The movable gate leaf 6 gradually disengages from the sealing copper strip 16, releasing the seal. Water flows out from the opening between the bottom of the movable gate leaf 6 and the gate base 1, realizing the water release function. When the movable gate leaf 6 rises to the highest position, the top of the valve mounting plate 7 abuts against the mounting groove 2 set on the top of the gate base 1, limiting the upward stroke of the movable gate leaf 6 and preventing overtravel.

[0027] When the gate needs to be closed, the hoist 15 drives the lead screw 14 to rotate in the opposite direction. The lead screw 14 drives the movable gate leaf 6 to slide downward along the slide groove 22. During the descent, the inclined surface of the adjusting wedge block 11 and the limiting block 3 cooperates to make the movable gate leaf 6 gradually approach the sealing copper strip 16 and finally fit tightly, achieving a water-stop seal.

[0028] During the pre-embedding of frame 17 in concrete, mounting holes 21 on frame 17 are used for connection with reinforcing bars, ensuring that frame 17 maintains its designed position during concrete pouring. Furthermore, a flow probe located on one side of the outer wall of gate base 1 continuously collects water flow data passing through the gate during gate operation, performing real-time flow detection. The collected flow data can be transmitted to a remote monitoring platform, enabling intelligent monitoring and management of the gate's operating status and providing data support for water conservancy scheduling.

[0029] Example 3 like Figures 1-4 As shown, the present invention also provides a modular gate installation method that can be disassembled as a whole, the method comprising the following steps: S1. Hang the frame 17 on the reinforcing bars through the mounting holes 21 and pour concrete so that the frame 17 is embedded in the concrete. S2. Hoist the gate seat to the position corresponding to the frame 17. Set a rubber soft seal 18 between the frame 17 and the gate base 1. Use anchor bolts 9 to pass through the gate base 1 and the rubber soft seal 18 in sequence and fix them to the frame 17. At the same time, fix the gate base 1 to the base plate 4 with the anchor bolts 9 to press the gate seat, the rubber soft seal 18 and the frame 17 together. Install the movable door leaf 6 on the gate seat and slide the adjusting wedge 11 inside the limit block 3. S3. When maintenance is required, remove the anchor bolts 9 and lift the gate seat together with the movable gate leaf 6 installed on it using the lifting plate 20, so that the gate seat is separated from the frame 17 and the rubber soft seal 18.

[0030] Specifically, during the installation phase, pre-embedding work is carried out first. Construction personnel connect the frame 17 to the reinforcing steel in the concrete structure through its mounting holes 21, precisely adjusting the position and orientation of the frame 17 to meet the design installation accuracy requirements. Subsequently, concrete is poured to firmly embed the frame 17 into the concrete structure, forming a stable load-bearing foundation. After the frame 17 is pre-embedded, sealing copper strips 16 are pre-installed in its internal insert grooves 19, and space is reserved for the installation of rubber soft seals 18 on the side of the frame 17 facing the gate base 1.

[0031] After the frame 17 is pre-embedded, the gate seat is installed. The gate seat is hoisted to the corresponding position on the frame 17, and a rubber soft seal 18 is placed between the frame 17 and the gate base 1. Then, anchor bolts 9 are used to pass through the gate base 1 and the rubber soft seal 18 in sequence and are fixedly connected to the pre-embedded frame 17. During the tightening of the anchor bolts 9, the rubber soft seal 18 is uniformly compressed to form an elastic sealing interface. At the same time, the gate base 1 and the base plate 4 are fixedly connected by the same set of anchor bolts 9, realizing the integrated fixation of all components of the gate seat. Finally, the movable gate leaf 6 is installed on the gate seat, so that the adjusting wedge 11 is slidably set inside the limit block 3, completing the installation of the overall gate structure.

[0032] During the maintenance and disassembly phase, when gate components are damaged and require repair, operators first remove the anchor bolts 9 to disconnect the fixed connection between the gate seat and the frame 17. Then, the lifting equipment is connected to the lifting plate 20 installed on one side of the frame 17, and the lifting equipment is activated to lift the gate seat, along with the movable gate leaf 6 mounted on it, as a single module. During lifting, the gate seat is completely separated from the frame 17 and the rubber soft seal 18, and the entire gate is raised to a safe area above the water surface. Maintenance personnel can then perform maintenance or replacement work on the gate from above the water surface, without the need for underwater operations or water outages. After maintenance, the installation steps are reversed to reinstall the entire gate module back in its original position, and the anchor bolts 9 are installed to restore its functionality.

[0033] By using a detachable connection between the gate seat and the pre-embedded frame 17, the modular design and overall disassembly and assembly function of the gate structure are realized, which greatly improves the convenience and safety of gate maintenance.

[0034] The above specific embodiments are merely several optional embodiments of the present invention. Based on the technical solutions of the present invention and the relevant teachings of the above embodiments, those skilled in the art can make various alternative improvements and combinations to the above specific embodiments.
