Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy projects, and more specifically to a prefabricated circular arc gate. Background Art

[0002] The maintenance gate is an essential supporting facility for hydraulic structures such as the lock head and chamber of a ship lock. However, it is usually only activated when the middle gate fails or needs maintenance, etc., and its usage frequency is low. The maintenance gate adopts an integral structure, which is large in volume and heavy in weight, making it inconvenient for manufacturing, transportation, and construction, and costly. Different orifice widths require separately fabricated maintenance gates with matching specifications, resulting in poor economy.

[0003] The arc gate is a gate with a part of the arc surface of a cylinder as the water retaining surface, consisting of a rotating gate body, embedded components, and a hoisting device. Although the shape of the rotating gate body of the arc gate has the advantage of smaller opening and closing force, it also has excellent performance in dispersing and transferring pressure, and does not require a gate slot. However, its installation and use are too cumbersome and require a large amount of manpower and material resources, making it not suitable for use as a maintenance gate with a low activation frequency. In addition, the shape of the rotating gate body of the arc gate determines that it cannot increase the height of the gate body through a laminated beam structure, thus unable to flexibly adjust the water retaining level requirements, and also inconvenient for transportation and installation. Summary of the Invention

[0004] To solve the above technical problems, the present invention proposes a prefabricated circular arc gate for use as a maintenance gate. The circular arc gate body can bear greater water pressure and evenly disperse the water pressure it receives. The prefabricated structure makes manufacturing, transportation, and construction convenient and the cost lower. Each component forming the gate is applicable to orifices of different widths, and can more flexibly, simply, and cost-effectively meet the water retaining requirements of gates of different widths. The height of the gate body can be increased to meet the water retaining requirements at different water levels.

[0005] To achieve the above object, the present invention adopts the following technical solutions:

[0006] A prefabricated circular arc gate, characterized in that:

[0007] The water retaining surface is a circular arc surface protruding outward towards the water inlet side, detachably arranged between the left and right gate slots, and is sequentially and detachably assembled from left to right by multiple gate bodies along the arc trajectory through connection structures of the same structural form. The leftmost is the left gate body, and the rightmost is the right gate body. The left end of the left gate body is provided with a cylindrical left gate shaft with the central axis parallel to the gate height direction, and the left gate shaft is always tangentially arranged in the left gate slot. The right end of the right gate body is provided with a cylindrical right gate shaft with the central axis parallel to the gate height direction, and the right gate shaft is always tangentially arranged in the right gate slot;

[0008] The assembled circular arc gate in the orifice is provided with at least one layer, and multiple layers of assembled circular arc gates are stacked layer by layer along the height direction of the gate.

[0009] The structural characteristics of the present invention also lie in:

[0010] Each layer of the assembled circular arc gate is detachably assembled from left to right by a left gate body and a right gate body along an arc track through a connecting structure.

[0011] Each layer of the assembled circular arc gate is sequentially assembled from left to right by a left gate body, at least one intermediate gate body, and a right gate body along an arc track, and adjacent gate bodies are detachably assembled through a connecting structure.

[0012] Each gate body includes a gate leaf and a strengthening structure. The surfaces of the gate leaves on the water-facing side of each gate body together form the water-blocking surface of the assembled circular arc gate. A strengthening structure is arranged on the water-backing side of the gate leaf. The strengthening structure includes multiple cross beams arranged at equal intervals along the radial direction of the gate body and multiple longitudinal beams connected between each cross beam and arranged at intervals along the circumferential direction of the gate body. The strengthening structure is provided with multiple groups along the height direction of the gate and is evenly distributed at equal intervals on the water-backing side of the gate body.

[0013] Hanging rings are provided at the left and right ends of the top of the strengthening structure of the topmost layer.

[0014] Side beams are respectively formed at one end side edges where adjacent gate bodies are connected. The side beams are arranged along the full height of the gate body, the plate surface is parallel to the radial direction of the gate body, and extends towards the water-facing side and the water-backing side respectively and is provided with bolt holes. The side beams of adjacent gate bodies are facing each other and closely attached, and are respectively fastened by bolts at each aligned bolt hole, and the joint between them is sealed by a rubber water stop strip.

[0015] The gap between the left gate shaft and the left gate slot and the gap between the right gate shaft and the right gate slot are respectively sealed by P-shaped rubber water stop strips. The joint between adjacent two layers of assembled circular arc gates is sealed by a circular arc rubber water stop strip, and the joint between adjacent gate bodies is sealed by a rubber water stop strip.

[0016] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0017] First, it can be used as a maintenance gate. When under the action of water pressure, the circular arc water-blocking surface can evenly disperse most of the water load to the entire circular arc surface and transmit it along the arc track to the gate slot, avoiding excessive local pressure on the gate, enabling the gate to bear greater water pressure and having a longer service life.

[0018] Second, under the same water retaining level requirement, compared with traditional gates, the present invention adopts a circular arc water-blocking surface, which can make the thickness of the gate smaller, so that the water retaining requirement can be completed with less materials, saving resources.

[0019] Thirdly, the present invention adopts a detachable and assembled structure. Compared with the traditional integral structure of the gate, on the one hand, by increasing or decreasing the number of middle gate bodies, the water retaining requirements of gates with different widths can be met. At the same time, during the assembly process, the left gate body is assembled with the left gate slot using a cylindrical left gate shaft, and the right gate body is assembled with the right gate slot using a cylindrical right gate shaft, which reduces the difficulty of gate body assembly. It can be used commonly between orifices with different widths, with high construction efficiency. Moreover, different water retaining level requirements can be met by stacking the multi-layer assembled circular arc gates layer by layer along the gate height direction. On the other hand, the convenience in aspects such as storage, transportation, construction, maintenance, and repair is significantly improved, and the cost is effectively controlled.

[0036] To make the objectives, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0037] Please refer to Figures 1 to 11 , the structure of the assembled arc-shaped gate in this embodiment is set as follows:

[0038] The water retaining surface is an arc-shaped surface protruding outward towards the water-facing side, which is detachably arranged between the left and right side gate slots, and is sequentially and detachably assembled from left to right by multiple gate bodies through connection structures of the same structural form along the arc track. The leftmost is the left gate body and the rightmost is the right gate body. A cylindrical left gate hinge with its central axis parallel to the gate height direction is provided at the left end of the left gate body, and the left gate hinge is always tangentially arranged in the left side gate slot. A cylindrical right gate hinge with its central axis parallel to the gate height direction is provided at the right end of the right gate body, and the right gate hinge is always tangentially arranged in the right side gate slot;

[0039] The assembled arc-shaped gate in the orifice has at least one layer. The multiple layers of assembled arc-shaped gates are stacked layer by layer along the gate height direction by using a hoisting device, and the total height is higher than the set water retaining height. The left gate hinges of each layer of assembled arc-shaped gates are stacked axially in the left side gate slot, and the right gate hinges are stacked axially in the right side gate slot.

[0040] In specific implementation, the corresponding structural settings of the assembled arc-shaped gate in this embodiment further include:

[0041] When the width of the gate orifice is small, each layer of assembled arc-shaped gate can be detachably assembled from left to right by the left gate body and the right gate body along the arc track through the connection structure.

[0042] When the width of the gate orifice is large, each layer of assembled arc-shaped gate is sequentially assembled from left to right by the left gate body, at least one middle gate body, and the right gate body along the arc track, and the adjacent gate bodies are detachably assembled through the connection structure.

[0043] Since the water-retaining surface of the gate in this embodiment is a circular arc surface protruding outward towards the water-facing side, and its maximum water-retaining width is the diameter of the arc, the width of the largest orifice needs to be considered before manufacturing the gate.

[0044] The gate bodies all include gate leaves and strengthening structures. The surfaces of the gate leaves on the water-facing side of each gate body together form the water-retaining surface of the assembled circular arc gate. A strengthening structure is arranged on the water-back side of the gate leaf. The strengthening structure includes multiple cross beams arranged at equal intervals along the radial direction of the gate body and multiple longitudinal beams connected between each cross beam and arranged at intervals along the circumferential direction of the gate body. The strengthening structure is provided with multiple groups along the height direction of the gate and is evenly spaced on the water-back side of the gate body. The cross beam and the longitudinal beam are arc-shaped I-beams.

[0045] Hanging rings are provided at the left and right ends of the top of the uppermost strengthening structure, and the hanging rings are arranged on the cross beam.

[0046] Side beams are respectively formed at one end side along which two adjacent gate bodies are joined. The side beams are arranged along the full height of the gate body, the plate surface is parallel to the radial direction of the gate body, and extend towards the water-facing side and the water-back side respectively and are provided with bolt holes. The side beams of two adjacent gate bodies are facing each other and closely attached, and are respectively fastened by bolts at each aligned bolt hole, and the joint between them is sealed by a rubber water stop strip.

[0047] The left gate shaft and the left gate slot, and the right gate shaft and the right gate slot are respectively sealed by P-shaped rubber water stop strips. The joints between adjacent two layers of the assembled circular arc gates are sealed by circular arc rubber water stop strips, and the joints between adjacent gate bodies are sealed by rubber water stop strips.

[0048] The left gate body can adjust its installation position towards the water-facing side or the water-back side within the range restricted by the left gate shaft in the left gate slot, and the right gate body can adjust its installation position towards the water-facing side or the water-back side within the range restricted by the right gate shaft in the right gate slot, so that when assembled to orifices of different widths, the left and right gate bodies can be adjusted to adapt to the increase or decrease in the number of intermediate gate bodies.

[0049] As a reference, the installation method of the assembled circular arc gate in this embodiment is as follows:

[0050] Step 1: Before assembling the maintenance gate, it is necessary to measure the orifice width and determine the height of the water-retaining level, determine the number of intermediate gate bodies according to the orifice width, and determine the number of layers of the assembled circular arc gate according to the height of the water-retaining level;

[0051] Step 2: Before hoisting, assemble each door body in sequence from left to right according to the order of the left door body → the middle door body → the right door body. Before assembly, slightly adjust the positions of each door body to align and fit the side beams carried by adjacent door bodies, install rubber waterstops between them, and then use bolts to connect the side beams of adjacent door bodies to assemble them into one body. Thus, the installation of the single-layer assembled circular arc gate is completed; after assembly, use a hoisting device to hoist, insert the left door shaft of the left door body into the left door groove on the left side, and insert the right door shaft of the right door body into the right door groove on the right side, ensuring that the P-shaped rubber waterstops at the left and right door shafts are respectively closely attached to the inner walls of the left and right door grooves.

[0052] Step 3: Referring to Step 2, complete the assembly of the second-layer assembled circular arc gate on the basis of the first-layer assembled circular arc gate, and install circular arc rubber waterstops at the joints between adjacent two layers of assembled circular arc gates.

[0053] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and purposes of the present invention. The scope of the present invention is defined by the claims and their equivalents.
