Description

Technical Field

[0001] The utility model relates to the technical field of water conservancy and hydropower engineering, in particular to a shore - slope type trash rack maintenance passageway. Background Technique

[0002] The intake / outlet is one of the main buildings of the water conveyance system of a hydropower station, used for the intake / outlet of the water conveyance system. As a conventional component of the intake, the trash rack needs to be regularly maintained and replaced. The function of the trash rack maintenance passageway is to connect the trash rack maintenance platform and the reservoir - surrounding road (maintenance platform), and it is the only passageway for the maintenance and replacement of the trash rack. Therefore, the layout of the trash rack passageway is very important for the long - term operation of the trash rack maintenance and replacement and the intake / outlet.

[0003] At present, in water conservancy and hydropower projects, the maintenance passageway of the intake / outlet mainly adopts the combination of a trash rack maintenance bent and a traffic bridge. Due to the excessive height of the trash rack maintenance bent and the traffic bridge, the seismic stability is poor, the design and construction difficulty is large, and the project investment is high. Content of the Utility Model

[0004] The purpose of the utility model is to provide a shore - slope type trash rack maintenance passageway with simple structural layout, small project quantity, low construction difficulty and convenient operation and management, overcoming the problems of poor seismic stability, high construction difficulty and high investment of the trash rack maintenance passageway of the trash rack bent + traffic bridge.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is as follows: A shore - slope type trash rack maintenance passageway includes a maintenance passageway and a transportation track. The maintenance passageway is a ground structure, located on the bedrock of the shore slope. The transportation track is installed on the maintenance passageway. One end of the maintenance passageway is connected to the trash rack maintenance platform of the intake / outlet, and the other end is connected to the reservoir - surrounding road maintenance platform.

[0006] The maintenance passageway is connected to the trash rack maintenance platform of the intake / outlet and the reservoir - surrounding road maintenance platform through a transfer platform or directly.

[0007] A maintenance personnel walking platform is arranged on the maintenance passageway.

[0008] The steps are arranged along the transportation track. The transportation track is two parallel tracks, and the steps are arranged in the middle of the two parallel tracks.

[0009] The maintenance passageway is a concrete maintenance passageway, and the cross - section of the concrete maintenance passageway is rectangular or any other feasible shape.

[0010] The beneficial effects of this utility model are: it can effectively solve the problems of excessive height of the trash rack maintenance frame and traffic bridge at the inlet / outlet of hydropower stations, poor seismic stability, high construction difficulty, and high project investment. It provides a new approach to the layout of trash rack channels. The bank slope trash rack maintenance channel can effectively reduce the height of the trash rack frame, eliminate the need for traffic bridges, has a simple structure, good seismic performance, is convenient for construction and operation management, and requires less project investment. It can be widely used in water conservancy and hydropower projects. Attached Figure Description

Detailed Implementation

[0016] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the scope of the present utility model.

[0017] In the description of this utility model, it should be noted that the terms "upper", "middle", "lower", "inner", "outer", "both sides", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the purpose of simplifying the description of this utility model and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0019] like Figures 1-4 As shown, the slope-type trash rack maintenance channel of this utility model includes a maintenance channel 1 and a transport track 2. The maintenance channel 1 is a ground structure, located on the bedrock of the slope. The transport track 2 is installed on the maintenance channel 1. One end of the maintenance channel 1 is connected to the trash rack maintenance platform 5 at the inlet / outlet, and the other end is connected to the maintenance platform 8 of the ring road around the reservoir.

[0020] Furthermore, the maintenance channel 1 is connected, either via a transfer platform or directly to the trash rack maintenance platform 5 at the inlet / outlet and the maintenance platform 8 on the ring road around the reservoir.

[0021] Furthermore, the maintenance passage 1 is equipped with steps 3 for maintenance personnel to walk on.

[0022] Preferably, the step 3 is arranged along the transport track 2, which consists of two parallel tracks, and the step 3 is located between the two parallel tracks.

[0023] Furthermore, the maintenance access channel 1 is a concrete maintenance access channel, and the cross-section of the concrete maintenance access channel is rectangular or any other feasible shape.

[0024] This utility model utilizes a bank-slope type trash rack maintenance access at the inlet / outlet, which effectively reduces the height of the trash rack frame and eliminates the need for traffic bridges. The bank-slope type trash rack maintenance access structure provides a new approach to trash rack access layout, effectively reducing the height of the trash rack frame, eliminating traffic bridges, and featuring a simple structure, good seismic resistance, convenient construction and operation management, and low project investment. It can be widely applied in water conservancy and hydropower projects.

[0025] The following is a detailed description, using a large-scale project that adopted the technical solution of this utility model as an example, with accompanying drawings: The height of the ring road (maintenance platform) of a certain project is 226.0m. If a trash rack frame + traffic bridge is set up as a trash rack maintenance passage, the height of the trash rack frame will be 41.9m and the height of the traffic bridge will be 54.5m. The seismic fortification intensity of the project is VIII. The height of both the trash rack frame and the traffic bridge is relatively high, resulting in poor seismic stability, high construction difficulty, and high project investment. Therefore, a bank slope type trash rack maintenance passage structure is adopted, eliminating the traffic bridge and reducing the height of the trash rack frame to 6.9m. This arrangement has a simple structure, good seismic effect, convenient construction and operation management, and low project investment.

[0026] The above description is only a preferred embodiment of the utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications should also be considered within the protection scope of the utility model.
