Description

Technical Field

[0001] This invention relates to the field of water conservancy engineering technology, specifically to an arc-shaped gate. Background Technology

[0002] Gates are an important component of hydraulic structures. In water conservancy projects, operators use control equipment to drive the movable gate body to open and close the gate, thereby achieving purposes such as intercepting water flow, controlling water level, regulating flow, and discharging sediment and floating debris. Among them, arc-shaped gates are widely used as working gates in various types of waterways due to their lower opening and closing force and better hydraulic conditions.

[0003] like Figure 1 As shown, in existing arc-shaped gates, both horizontal and bidirectional rotating arc-shaped gates require a certain gap to ensure normal operation. Furthermore, existing arc-shaped gates place the bottom water-stop on the water-retaining surface and embed parts in the gate housing. Water is stopped when the bottom water-stop is in contact with the embed parts; when the bottom water-stop is not in contact with the embed parts, a gap exists between the bottom water-stop and the gate housing to allow for smooth gate rotation.

[0004] The shortcomings of the aforementioned prior art are as follows: On the one hand, since the bottom waterstop is set on the water-blocking surface, the thickness of the bottom waterstop itself and the gap between the bottom waterstop and the door frame result in an excessively large gap between the door and the door frame (which can reach more than 120mm in actual production). This causes some large sand and gravel to enter from the gap between the door and the door frame and deposit into the waterstop area, thereby jamming the door, affecting its normal operation, and even damaging the waterstop. On the other hand, in actual production, the bottom waterstop is welded to the steel parts on the door panel. The welding process causes excessive deformation of the panel, requiring the door to be reshaped to meet the usage requirements, but this process is relatively complicated. Summary of the Invention

[0005] In view of the shortcomings of the prior art, the purpose of this invention is to provide an arc-shaped gate that can better solve the problem of sand and gravel jamming and can avoid deformation of the gate surface during the production process.

[0006] The arc-shaped gate provided by the present invention includes a gate body, a gate housing, a support arm, a drive device, and a bottom water-stopping device;

[0007] The gate includes a water-retaining surface, which is arc-shaped; the gate is located at the bottom of the river; the drive device is connected to the support arm, and the support arm is connected to the gate; the drive device drives the gate to rotate into or out of the gate via the support arm.

[0008] The bottom water-stopping device includes a bottom water-stopping component, an mounting component, and an embedded component. The embedded component is installed on the surface of the door frame, and there is a gap between the water-blocking surface and the door frame during the door rotation process. The mounting component is connected to the door body, and the bottom water-stopping component is installed on the mounting component and located on the lower side of the door body in the water-blocking state. During the door rotation process, the bottom water-stopping component is outside the gap between the door body and the door frame, and the bottom water-stopping component and the embedded component achieve water stop through contact.

[0009] In this technical solution, by adopting the structural design described above, the bottom water-stop component is placed outside the gap between the water-retaining surface and the gate housing. This allows for the space between the water-retaining surface and the embedded component to accommodate only the deformation of the gate body, eliminating the need to consider the space required for the bottom water-stop component on the water-retaining surface. This significantly reduces the actual gap between the gate body and the gate housing. This structural design prevents large sand and gravel from entering the gap between the gate body and the gate housing, avoiding interference with the normal operation of the gate and effectively solving the problem of sand and gravel entrapment in the bottom water-stop sealing area. Furthermore, since the bottom water-stop component is not placed on the water-retaining surface, the welding step between the bottom water-stop component and the water-retaining surface is eliminated during manufacturing, thus preventing deformation of the water-retaining surface during welding. The water-retaining state includes situations where the gate body is not completely rotated out of the gate housing to achieve water retention. The material of the mounting component can be set in various forms according to actual conditions, such as an alloy structure.

[0010] Preferably, when the door body is turned into the gate, the gap between the connection between the mounting part and the bottom water stop and the gate is greater than the gap between the water-retaining surface and the gate.

[0011] In this technical solution, the above-described structural design allows the arc-shaped gate provided by this invention to use a larger water-stopping component. Since the gaps between the connection between the mounting component and the water-stopping component and the gate housing, and the gap between the water-retaining surface and the gate housing, are independent of each other, even when the water-stopping component is large, resulting in a larger gap between the connection between the mounting component and the water-stopping component and the gate housing, a smaller gap can still be provided between the water-retaining surface and the gate housing.

[0012] Preferably, it also includes a first sand-blocking plate, which is located above the bottom water-stop sealing area. One end of the first sand-blocking plate is fixed to the door frame or embedded part, and the other end points towards the door body.

[0013] In this technical solution, a first sand-blocking plate is installed above the bottom water-stop sealing area through the structural design described above. This structural design allows the first sand-blocking plate to block larger sand and gravel outside the bottom water-stop sealing area. Even if smaller sand and gravel enter the gap between the gate body and the gate housing, they will not cause jamming and thus affect the normal operation of the gate body. This further solves the problem of sand and gravel jamming in the bottom water-stop sealing area during the operation of the arc-shaped gate. The so-called "bottom water-stop sealing area" refers to the area where the bottom water-stop component and the embedded component contact the water-stopping element. The material of the first sand-blocking plate can be set in various forms according to the actual situation, such as elastic or rigid materials. The length of the first sand-blocking plate can also be set according to the actual situation.

[0014] Preferably, the first sand-blocking plate is made of an elastic material.

[0015] In this technical solution, through the above-described structural design, when the bottom water-stop component rotates to the first sand-blocking plate during the operation of the arc-shaped gate, the force exerted by the first sand-blocking plate on the bottom water-stop component is relatively small, thereby reducing the wear rate of the bottom water-stop component and improving its service life.

[0016] Preferably, the first sand-blocking plate is a straight plate structure or a curved plate structure.

[0017] In this technical solution, the structure of the first sand-blocking plate can be selected according to the actual situation through the structural design described above.

[0018] Preferably, it also includes a second sand-blocking plate, which is fixed to the door body and is located above the bottom water-stopping component in the water-blocking state.

[0019] In this technical solution, through the structural design described above, a second sand-blocking plate is installed on the door body, thereby further blocking sand and gravel entering the gap between the door body and the gatehouse outside the water-stopping area. The second sand-blocking plate can be made of different materials depending on the actual situation, such as elastic or rigid materials; the length of the second sand-blocking plate can also be set according to the actual situation.

[0020] Preferably, the second sand-blocking plate is made of a rigid material.

[0021] In this technical solution, the strength and service life of the second sand-blocking plate can be improved through the structural design described above.

[0022] Preferably, when the bottom waterstop component contacts the embedded part to stop the water flow, the second sand-blocking plate and the first sand-blocking plate are in contact with each other.

[0023] In this technical solution, by adopting the above-described structural design, when the bottom water-stop component contacts the embedded part to stop the water flow, the first and second sand-blocking plates can completely seal the gap between the gate body and the gate housing, thereby blocking sand and gravel above the water-stopping area. When the arc-shaped gate rotates, the first and second sand-blocking plates separate, thereby releasing the above-mentioned sealing state, allowing smaller sand and gravel to move downstream along the gap, while larger sand and gravel are blocked on the upstream side of the bottom water-stopping sealing area. Furthermore, during the rotation of the gate body, the friction between the larger sand and gravel and the gate body is relatively small, thus ensuring the normal operation of the arc-shaped gate.

[0024] Preferably, the device further includes several reinforcing ribs, one end of which is fixedly connected to the mounting component, and the other end is fixedly connected to the door body or the support arm.

[0025] In this technical solution, the structural design described above can further improve the strength of the mounting components, and the reinforcing ribs can simultaneously improve the strength of the gate body, enabling the arc-shaped gate to operate stably.

[0026] Preferably, the bottom waterstop is P-shaped, U-shaped, or V-shaped.

[0027] In this technical solution, the shape of the bottom waterstop can be selected according to the actual situation through the structural design described above.

[0028] Preferably, the mounting component is a steel structure.

[0029] In this technical solution, the structural design described above can give the mounting components high strength, preventing the relative positions of the mounting components and the bottom water-stopping components from changing during the operation of the arc gate, which could lead to water-stopping failure.

[0030] Preferably, the mounting component and the bottom waterstop are adjustable.

[0031] In this technical solution, through the structural design described above, adjustable mounting components and bottom waterstop components are provided, so that the mounting components and bottom waterstop components can be adjusted to a suitable position according to the actual situation to ensure the water-stopping effect.

[0032] Compared with the prior art, the present invention has the following beneficial effects:

[0033] 1. The arc-shaped gate provided by the present invention, by improving the structure of the bottom water-stopping component, prevents large-volume sand and gravel from entering the gap between the gate body and the gate housing, thereby avoiding the impact of large-volume sand and gravel entering the gap on the normal operation of the gate body, and can effectively solve the problem of sand and gravel stuck in the bottom water-stopping sealing area.

[0034] 2. The arc-shaped gate provided by the present invention eliminates the step of welding the bottom water stop and the water-retaining surface during production and processing because the bottom water stop is not set on the water-retaining surface. This avoids deformation of the water-retaining surface during the welding process, speeds up production and construction, and reduces project costs. Attached Figure Description

[0060] Example 1

[0061] like Figures 2 to 4 As shown, this embodiment provides an arc-shaped gate, including a gate body 1, a support arm 3, a drive device 4, a gate housing 2, and a bottom water-stopping device 5. The gate body 1 includes a water-blocking surface 11, which is arc-shaped.

[0062] Specifically, gate 2 is located at the bottom of the river channel, and the shape of the surface of gate 2 matches the water-retaining surface 11 so that gate 1 can move smoothly relative to gate 2. There is a gap between the surface of gate 2 and water-retaining surface 11 to ensure that gate 1 can still move smoothly relative to gate 2 even if it deforms due to factors such as temperature. Drive device 4 is connected to support arm 3, and support arm 3 is connected to gate 1. Drive device 4 drives gate 1 to rotate into or out of gate 2 through support arm 3.

[0063] The bottom water-stopping device 5 includes a bottom water-stopping component 52, a mounting component 51, and an embedded component 53. The embedded component 53 is disposed on the surface of the door frame 2, and a gap exists between the water-blocking surface 11 and the door frame 2 during door rotation. The mounting component 51 is connected to the door body 1, and the bottom water-stopping component 52 is disposed on the mounting component 51 and located on the lower side of the door body 1 in the water-blocking state. During door rotation, the bottom water-stopping component 53 is outside the gap between the door body 1 and the door frame 2, and the bottom water-stopping component 52 and the embedded component 53 achieve water stop through contact. Regarding the shape of the bottom water-stopping component 52, it can be configured into various shapes according to actual conditions, such as P-shaped, U-shaped, or V-shaped.

[0064] The arc-shaped gate provided in this embodiment, by placing the bottom water-stop component 52 outside the gap between the water-retaining surface 11 and the gate housing 2, allows the gap between the water-retaining surface and the embedded part 53 to be reserved only for the deformation of the gate body 1, without considering the space required for setting the bottom water-stop component 52 on the water-retaining surface. This significantly reduces the actual gap between the gate body 1 and the gate housing 2, which can be reduced from 120mm to 60mm in actual production. This structural design prevents large-volume sand and gravel from entering the gap between the gate body 1 and the gate housing 2, thus avoiding the impact of large-volume sand and gravel entering the gap on the normal operation of the gate body 1 and effectively solving the problem of sand and gravel entrapment in the bottom water-stop sealing area. In addition, since the bottom water-stop component 52 is not placed on the water-retaining surface, the step of welding the bottom water-stop component 52 to the water-retaining surface is eliminated during production and processing, thereby avoiding deformation of the water-retaining surface during the welding process.

[0065] As for the mounting component 51, it is a steel structure. This structural design gives the mounting component 51 high strength, preventing the water-stopping mechanism from failing due to changes in the relative positions of the mounting component 51 and the bottom water-stop component 52 during the operation of the arc-shaped gate. It should be noted that in this embodiment, the mounting component 51 is a steel structure; however, in other embodiments, the mounting component 51 may also be made of other materials with high structural strength, such as an alloy structure, depending on the actual situation.

[0066] Furthermore, the arc-shaped gate provided in this embodiment also includes several reinforcing ribs 8. One end of the reinforcing rib 8 is fixedly connected to the mounting member 51, and the other end is fixedly connected to the gate body 1 or the support arm 3. This structural design can further improve the strength of the mounting member 51, and the reinforcing rib 8 can simultaneously improve the strength of the gate body 1, enabling the arc-shaped gate to operate stably.

[0067] Furthermore, the mounting component 51 and the bottom water-stop component 52 are configured as adjustable structures. This structural design allows the arc-shaped gate provided in this embodiment to be adjusted to a suitable position according to actual conditions to ensure the water-stopping effect.

[0068] Example 2

[0069] like Figures 5 to 6 As shown, this embodiment provides an arc-shaped gate, which has a structure that is roughly the same as the arc-shaped gate in the first embodiment. The difference is that the arc-shaped gate in this embodiment, based on the structure of the arc-shaped gate in the first embodiment, also includes a first sand-blocking plate 6.

[0070] Specifically, one end of the first sand-blocking plate 6 is fixed to the gate housing 2 or the embedded part 53, and the other end points towards the gate body 1, with the first sand-blocking plate 6 positioned above the embedded part 53. When the gate body 1 rotates into the gate housing 2, the first sand-blocking plate 6, positioned above the embedded part 53, can block small sand and gravel that enter the gap between the gate body 1 and the gate housing 2, keeping them in the water-stopping area, i.e., above the contact area between the bottom water-stopping part 52 and the embedded part 53, preventing sand and gravel from depositing in the water-stopping area. This structural design ensures that even if small-volume sand and gravel enter the gap between the gate body 1 and the gate housing 2, it will not cause jamming and affect the normal operation of the gate body 1, thereby further solving the problem of sand and gravel jamming in the bottom water-stopping sealing area during the operation of the arc-shaped gate.

[0071] Regarding the material of the first sand-blocking plate 6, it can be made of an elastic material, such as rubber. This structural design allows the first sand-blocking plate 6 to exert a relatively small force on the bottom water-stop 52 when the bottom water-stop 52 rotates to the first sand-blocking plate 6 during the operation of the arc-shaped gate, thereby reducing the wear rate of the bottom water-stop 52 and improving its service life. It should be noted that in this embodiment, the first sand-blocking plate 6 is made of an elastic material; however, in other embodiments, the first sand-blocking plate 6 can be made of other materials depending on the actual situation, such as a rigid material.

[0072] Regarding the shape of the first sand-blocking plate 6, it can be set to different shapes according to the actual situation, such as a straight plate structure or a curved plate structure. In this embodiment, the first sand-blocking plate 6 adopts a curved plate structure.

[0073] Furthermore, the arc-shaped gate provided in this embodiment also includes a second sand-blocking plate 7. The second sand-blocking plate 7 is fixed to the gate body 1 and is located above the bottom water-stopping member 52 in the water-blocking state. This structural design allows the second sand-blocking plate 7 to further block sand and gravel entering the gap between the gate body 1 and the gate housing 2 outside the water-stopping area.

[0074] Regarding the material of the second sand-blocking plate 7, it can be made of different materials depending on the actual situation, such as an elastic structure or a rigid structure. In this embodiment, the second sand-blocking plate 7 is a rigid structure.

[0075] Regarding the lengths of the first sand-blocking plate 6 and the second sand-blocking plate 7, different configurations can be set according to actual conditions. In this embodiment, the length of the first sand-blocking plate 6 is greater than the length of the second sand-blocking plate 7.

[0076] Furthermore, when the bottom water-stopping component 52 contacts the embedded component 53 to stop the water flow, the second sand-blocking plate 7 contacts the first sand-blocking plate 6. This structural design allows the first sand-blocking plate 6 and the second sand-blocking plate 7 to completely seal the gap between the gate body 1 and the gate housing 2 when the bottom water-stopping component 52 contacts the embedded component 53 to stop the water flow, thereby blocking sand and gravel above the water-stopping area. When the arc-shaped gate rotates, the first and second sand-blocking plates separate, thereby releasing the above-mentioned sealing state, allowing smaller sand and gravel to move downstream along the gap, while larger sand and gravel are blocked on the upstream side of the bottom water-stopping sealing area. Moreover, during the rotation of the gate body, the friction between the larger sand and gravel and the gate body is small, thereby ensuring the normal operation of the arc-shaped gate.

[0077] Regarding the material of the second sand-catching plate 7, it is made of a rigid material. This structural design can improve the structural strength and service life of the second sand-catching plate 7. It should be noted that in this embodiment, the second sand-catching plate 7 is made of a rigid material, while in other embodiments, the second sand-catching plate 7 may be made of other materials, such as an elastic material.

[0078] 3rd Embodiment

[0079] This embodiment provides an arc-shaped gate, which is largely the same as the arc-shaped gate provided in the second embodiment. The difference is that the second embodiment simultaneously provides a first sand-blocking plate 6 and a second sand-blocking plate 7 to further block sand and gravel outside the water-stopping area.

[0080] In this embodiment, such as Figure 7 As shown, only the second sand-blocking plate 7 is set, which further blocks sand and gravel outside the water-stopping area.

[0081] Example 4

[0082] like Figure 8 As shown, this embodiment provides an arc-shaped gate, which is roughly the same as the arc-shaped gate provided in the first embodiment. The difference is that the first embodiment uses a V-shaped bottom water-stop component. When the gate body 1 turns into the gate 2, the gap between the connection between the mounting component 51 and the bottom water-stop component 52 and the gate 2 is greater than the gap between the water-blocking surface 11 and the gate 2.

[0083] In this embodiment, the bottom water stop is set to an Ω shape. When the door 1 turns into the door 2, the gap between the connection between the mounting part 51 and the bottom water stop 52 and the door 2 is smaller than the gap between the water-blocking surface 11 and the door 2.

[0084] The specific embodiments of the present invention have been described above. Based on the above description, those skilled in the art can make various changes and modifications without departing from the technical concept of the present invention.
