Description

Technical Field

[0001] This utility model relates to a dike, specifically to a flood-resistant structure for a dike. Background Technology

[0002] A dam is a civil engineering structure used for flood control, which mainly uses barriers raised on both sides of the riverbed to control water flow.

[0003] Generally, the height of the dikes on both sides of a river needs to be controlled, partly due to the difficulty of construction, and partly to avoid impacting the local ecological environment.

[0004] However, during certain periods of severe flooding, the dikes built under certain restrictions may be insufficient in their ability to control floods, making it easy for floodwaters to overflow the top of the dikes and cause flood disasters. Utility Model Content

[0005] In view of the technical problem that existing dikes, which are constructed under certain restrictions, have insufficient flood control capacity during special flood periods, this utility model provides a flood control structure for dikes. By designing a structure that can freely raise the height of the dike, the flood control capacity during special flood periods is improved.

[0006] The technical solution of this utility model is:

[0007] A flood-resistant structure for a dam, comprising:

[0008] The main body of the dam, on the side located within the river channel, has a stepped structure;

[0009] The baffle is placed on the top step of the side of the dam where the main body is a stepped structure;

[0010] Multiple racks are arranged parallel to each other on the baffle, and the length direction of the racks is consistent with the inclination direction of this side of the dam body;

[0011] Multiple gears mesh with each rack in a one-to-one correspondence;

[0012] The motor has its output shaft connected to a gear for power.

[0013] Optionally, a support slide is provided on the top step of the main body of the dam, and a support component matching the support slide is provided on the baffle.

[0014] Optionally, the support member is a T-shaped structure, and the support slide has a channel with a T-shaped cross section.

[0015] Optionally, all gears are mounted on a single drive shaft, which is powered to the output shaft of the motor.

[0016] Optionally, a gear meshes with a drive tooth, and the drive tooth is poweredly connected to the output shaft of the motor via a pair of bevel gears.

[0017] Optionally, the motor can be detachably mounted on top of the main body of the dam.

[0018] Optionally, a viewing platform is provided on the main body of the dam, with the motor and gears located between the viewing platform and the top of the main body of the dam.

[0019] Optionally, the front end of the observation deck is rotatably equipped with a cover plate, which is located directly above the baffle.

[0020] Optionally, the observation deck is equipped with an openable manhole cover at its base, located directly above the motor.

[0021] Compared with the prior art, the beneficial effects of this utility model are:

[0022] The side of the dam located within the river channel is designed with a stepped structure. This design enhances the strength of the dam and provides a mounting location for the baffle. By sliding the baffle onto the dam body, during periods of severe flooding, a motor-driven gear, which in turn drives a rack, moves the baffle upwards, thereby increasing the height of the dam body. This prevents floodwaters from overflowing the top of the dam during severe floods. Attached Figure Description

[0029] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0030] Example:

[0031] See Figure 1 , Figure 2 and Figure 3 This embodiment discloses a flood-control structure for a dam, including a dam body 10, a baffle 20, a rack 31, a gear 32, and a motor 33. The baffle 20 is slidably disposed on one side of the dam body 10, the rack 31 is disposed on the baffle 20, the gear 32 meshes with the rack 31, and the motor 33 is poweredly connected to the gear 32. The motor 33, gear 32, and rack 31 can directly drive the baffle 20 to slide on the dam body 10.

[0032] Specifically, the dam body 10 has a stepped structure on the side located inside the river channel, and this side of the dam body 10 is inclined. A baffle 20 is slidably installed on the top step of the dam body 10 on the side located inside the river channel. The baffle 20 is also installed along the inclined direction and can slide in the upward inclined direction.

[0033] There is a gap between the baffle 20 and the dam body 10. A rack 31 is provided in this gap. The rack 31 is set on the baffle 20, and multiple racks 31 are arranged parallel to each other on the baffle 20. A gear 32 is engaged on each rack 31. The top of the baffle 20 is located above the top of the dam body 10, so that the gear 32 is located on the top of the dam body 10 and can mesh with the rack 31.

[0034] All gears 32 are poweredly connected to the output shaft of motor 33, and motor 33 is also located on the top of dam body 10.

[0035] In this embodiment, the side of the dam body 10 located within the river channel is designed as a stepped structure. This enhances the strength of the dam body 10 and provides an installation location for the baffle 20. By sliding the baffle 20 onto the dam body 10, during periods of severe flooding, the motor 33 drives the gears, and the gear 32 drives the rack 31, thereby moving the baffle 20 upwards. This increases the height of the dam body 10, preventing floodwaters from overflowing the top of the dam body 10 during severe flooding.

[0036] In one specific embodiment:

[0037] A support slide 34 is provided on the top step of the main body 10 of the dam, and the extension direction of the support slide 34 is consistent with the length direction of the rack 31. A support member 35 is provided on the baffle 20, and the support member 35 is fitted into the support slide 34.

[0038] Generally, multiple support slides 34 and support components 35 are installed between the main body 10 of the dam and the baffle 20 to achieve stable support for the baffle 20 and ensure that the baffle 20 has sufficient strength to resist floods after being raised.

[0039] Preferably, the support member 35 has a T-shaped cross-section, and the support slide 34 has a T-shaped channel. This structural design allows the baffle 20 to be connected to the dam body 10 via the support member 35 and the support slide 34, and also enables support for the baffle 20 after it is raised.

[0040] In another specific embodiment:

[0041] All gears 32 are coaxially mounted on a drive shaft 36, which is poweredly connected to the output shaft of the motor 33. Specifically, a drive tooth 37 meshes with one of the gears 32. The drive tooth 37 is rotatably mounted on the top of the dam body 10 via a support base. A bevel gear is also coaxially mounted on the drive tooth 37, while another bevel gear is mounted on the output shaft of the motor 33. The two bevel gears mesh with each other.

[0042] In this embodiment, the power of the motor 33 is transmitted to the gear 32 through a pair of bevel gears between the output shaft of the motor 33 and the drive gear 37, thereby driving the gear 37 31 and the baffle 20 to rise.

[0043] In another specific embodiment:

[0044] A viewing platform 41 is provided on the main body 10 of the dam. The motor 33 and gear 32 are located between the viewing platform 41 and the top of the main body 10 of the dam. A cover plate 42 is rotatably provided at the front end of the viewing platform 41. The cover plate 42 is located directly above the baffle 20. An openable manhole cover 43 is provided at the bottom of the viewing platform 41. The manhole cover 43 is located directly above the motor 33.

[0045] This design avoids exposing the top of the baffle 20 and the gear 32, thus slowing down the aging of the gear 32. Meanwhile, the structure of the manhole cover 43 is designed to facilitate the installation and removal of the motor 33.

[0046] In the actual construction process, several baffle structures 20 will be designed along the extension direction of the river channel, and each baffle structure 20 requires a motor 33 for driving. In this embodiment, by setting a manhole cover 43 structure at the bottom of the viewing platform 41, when it is necessary to raise the baffle 20, one motor 33 can be used in sequence with different baffle structures 20.

[0047] The embodiments described above merely illustrate specific implementations of this utility model, and while the descriptions are detailed, they should not be construed as limiting the scope of this utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these modifications and improvements all fall within the protection scope of this utility model.
