Description

Technical Field

[0001] This utility model mainly relates to the field of water conservancy and hydropower engineering technology, and in particular to a frame structure for the opening and closing machine room of a ground or semi-underground gate well. Background Technology

[0002] Gate wells are one of the main structures in the water conveyance system of a hydropower station. They are used to quickly close emergency gates in emergency situations to ensure the safety of downstream structures. For hydropower stations without intake and surge tanks, gate wells can also be used to eliminate or reduce water hammer pressure in the waterway when the generating units are shut down or suddenly shed load. When the generating units are started up or the load suddenly increases, they are used to supply the water required for the increased load of the generating units. When the unit load fluctuates, they can make corresponding responses and adjustments, playing a vital role in the safe operation of the hydropower station.

[0003] Currently, water conservancy and hydropower projects mainly utilize underground or semi-underground gate well superstructures or surface gate well superstructures. When terrain conditions do not allow for the construction of underground gate well superstructures, surface or semi-underground gate well superstructures can be used to address the issue of insufficient height in underground gate well superstructures and meet the operating conditions of the power station. Surface gate well superstructures can adopt circular, rectangular, or other feasible cross-sections, effectively reducing the height of the superstructure, which is beneficial to structural safety and overall stability, reduces construction difficulty, and saves on project investment.

[0004] For gate wells above ground or semi-underground, the layout of the gate well hoist room is quite difficult. If a ground hoist frame structure is used, the height of the frame columns will be affected by the ground height of the gate well upper chamber and will increase. If the frame columns are too high, it will be detrimental to the structure and the seismic resistance will be poor. In addition, the beams of the hoist frame can only be arranged as a single-span structure. For larger upper chambers, a single-span structure cannot meet the structural stress requirements. Utility Model Content

[0005] The purpose of this utility model is to provide a simple structural layout, small engineering workload, and convenient construction and operation management for the gate well upper chamber of a ground or semi-underground type. It overcomes the inability to arrange ground-type gate well frames in upper chambers above ground, provides a new approach for the layout of gate wells in ground-type upper chambers, and broadens the selection of gate well locations and water conveyance system layout schemes.

[0006] To achieve the above objectives, the technical solution adopted by this utility model is as follows: a frame structure for the opening and closing machine room of a ground or semi-underground gate well chamber, including frame columns and frame beams. The frame columns include outer frame columns on the outer perimeter and inner frame columns on the inner side. The frame beams are laid horizontally between the frame columns to form the frame structure of the opening and closing machine room. The bottom of the outer frame columns is supported on the top surface of the well wall of the gate well chamber, and the inner frame columns are supported inside the well of the gate well chamber.

[0007] The cross-section of the above-ground or semi-underground gate well chamber is oblong, rectangular, or any other feasible shape.

[0008] The beneficial effects of this utility model are: it can effectively solve the problem that ground-mounted gate hoisting machine room frames cannot be arranged in the upper chamber above the ground, providing a new approach for the arrangement of gate hoisting machine rooms in the upper chamber, broadening the selection of gate well locations and water conveyance system layout schemes, and the gate hoisting machine room frame structure is simple, convenient for construction and operation management, and can be widely used in water conservancy and hydropower projects.

[0011] 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.

[0012] 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.

[0013] 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.

[0014] like Figure 1 , 2 As shown, the gate hoisting machine room frame structure of the above-ground or semi-underground gate well chamber of this utility model includes frame columns and frame beams. The frame columns include outer frame columns 1 on the outer perimeter and inner frame columns 5 on the inner side. The frame beams 3 are laid horizontally between the frame columns to form the gate hoisting machine room frame structure. The bottom of the outer frame columns 1 is supported on the top surface of the well wall 2 of the gate well chamber, and the inner frame columns 5 are supported inside the well of the gate well chamber.

[0015] The cross-section of the upper chamber of the above-ground or semi-underground gate well is oblong, rectangular, or any other feasible shape. 4 represents the ground excavation line.

[0016] Specifically, when the height of the gate well upper chamber is above ground level, it cannot accommodate a ground-mounted hoist frame structure. This utility model provides a hoist frame structure comprising a gate well upper chamber and a wall-mounted hoist frame. The gate well upper chamber is a ground-level or semi-underground structure. The outer frame columns of the hoist room are arranged on the well wall, while the inner frame column structure provides the foundation for the upper frame. Using a wall-mounted hoist room frame structure, the frame columns are based on the well wall, reducing height. Furthermore, the inner frame columns are arranged within the well, allowing for multi-span structures. This wall-mounted hoist room frame structure effectively solves the problem of accommodating ground-mounted hoist frames in upper chambers above ground level, providing a new approach for arranging hoist rooms in ground-mounted upper chambers. It broadens the selection of gate well locations and water conveyance system layout schemes. The hoist room frame structure is simple, and construction and operation management are convenient.

[0017] The following is a detailed description of a large-scale project that adopted the technical solution of this utility model: The upper chamber of the water intake gate well of a certain project has a fixed elevation of 614.00m, and the ground elevation is about 609.40m. The upper chamber is 4.60m higher than the ground. The elevation of the upper chamber cannot meet the requirements for arranging the ground-type hoist frame structure. Therefore, the well wall type hoist frame structure of this utility model is adopted. The upper chamber of the gate well is a circular structure with an inner diameter of 16.0m. Both the upper chamber of the gate well and the hoist room frame structure are reinforced concrete structures. The top plate of the upper chamber is 614.00m, and the ground elevation is 609.40m.

[0018] 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.
