Description

Technical Field

[0001] This utility model relates to the field of floor structure technology, and in particular to a stage floor structure with lifting and drainage functions. Background Technology

[0002] In venues such as stage performances, stadiums, or large convention centers, water may sometimes accumulate on the stage floor due to performance effects (such as water curtain performances) or unexpected situations (such as water spraying or rainwater seepage). The presence of water not only seriously affects the safety of performers and personnel, but may also damage the electrical equipment and structure beneath the stage.

[0003] In existing technologies, stage floor drainage typically involves setting fixed drainage channels or holes on the floor surface. This type of drainage structure has significant drawbacks: First, the fixed raised drainage channels affect the flatness of the stage surface, hindering normal walking and the movement of props and equipment; second, dust and debris easily fall into the drainage holes or channels during non-drainage periods, causing blockages and preventing them from functioning properly when drainage is needed, making maintenance and cleaning inconvenient.

[0004] Therefore, there is an urgent need for a stage floor structure that can ensure a flat stage surface, provide efficient and reliable drainage, and prevent clogging. Utility Model Content

[0005] To solve the above problems, this utility model provides a stage floor structure with lifting and drainage functions, the specific technical solution of which is as follows: A stage floor structure with lifting and drainage function includes multiple interconnected floor components, a lifting and drainage component is provided between two interconnected floor components, and several lifting and drainage components are respectively connected to a main drainage pipe. The lifting and draining assembly includes a driving component, a lifting outer component, and a fixed inner component. The fixed inner component is vertically fixed between two adjacent floor assemblies and has a through cavity inside, which is connected to the main drain pipe. The lifting outer component is slidably sleeved outside the fixed inner component, and a drain outlet is provided on the side wall of the lifting outer component, which is connected to the through cavity. The driving component is driven by the lifting outer component and is used to drive the lifting outer component to lift.

[0006] Preferably, the driving component is a linear motor, an electric actuator, or a cylinder.

[0007] Preferably, the driving component includes a drive motor, a drive rack, and a drive link; the drive rack is slidably disposed, and the output end of the drive motor is driven to the drive rack to drive its linear movement; one end of the drive link is hinged to the drive rack, and the other end is hinged to the lifting outer component.

[0008] Preferably, a first sealing element is provided between the fixed inner component and the lifting outer component.

[0009] Preferably, a second seal is provided between the lifting outer component and the floor assembly.

[0010] Preferably, the height of the lifting outer component after it rises is 5-30mm higher than the upper surface of the floor assembly.

[0011] Preferably, the drain outlets are symmetrically arranged on both sides of the lifting outer component.

[0012] Preferably, it further includes a guide structure, which includes a vertically arranged guide groove and a slider correspondingly arranged on the inner side wall of the lifting outer component; the slider is embedded in the guide groove.

[0013] Preferably, a negative pressure pump is connected to the main drain pipe to generate negative pressure within the main drain pipe.

[0014] Compared with the prior art, the present invention has the following beneficial effects: Firstly, in the non-drainage state, the lifting external component descends to be flush with the upper surface of the floor assembly, ensuring the complete flatness of the stage floor, facilitating personnel movement and equipment relocation, and eliminating safety hazards. In the drainage state, the drive component can quickly lift the lifting external component, exposing the drainage outlet on its side, allowing accumulated water to be collected from both sides simultaneously and discharged into the main drainage pipe, making drainage proactive and efficient.

[0015] Secondly, this solution prevents water from leaking through the gaps between the lifting outer component and the fixed inner component, and between the lifting outer component and the floor assembly, by setting up a first sealing element and a second sealing element, thus protecting the lower structure of the stage.

[0016] Thirdly, this solution includes a negative pressure system that creates negative pressure in the main drain pipe, generating strong suction to further accelerate the drainage of accumulated water. It is particularly suitable for scenarios where large amounts of water need to be cleared quickly. Attached Figure Description

[0019] The embodiments of this disclosure will be further described in detail below with reference to the accompanying drawings and examples. The detailed description of the embodiments and the accompanying drawings are used to illustrate the principles of this disclosure by way of example, but should not be used to limit the scope of this disclosure. This disclosure can be implemented in many different forms and is not limited to the specific embodiments disclosed herein, but includes all technical solutions falling within the scope of the claims.

[0020] These embodiments are provided to make the disclosure thorough and complete, and to fully express the scope of the disclosure to those skilled in the art. It should be noted that, unless otherwise specifically stated, the relative arrangement of components and steps, material composition, numerical expressions, and values ​​set forth in these embodiments should be interpreted as exemplary only and not as limiting.

[0021] like Figures 1 to 3 As shown, a stage floor structure with lifting and drainage functions is constructed by splicing together multiple standard floor components 1 to form the entire stage surface. Lifting and drainage components 2 are installed at the joints between every two adjacent floor components 1. The bottoms of all lifting and drainage components 2 are connected to a common drainage manifold 3 via pipes, which discharges the collected water to a designated location.

[0022] The lifting and drainage assembly 2 is the core of this utility model, mainly comprising a drive component 21, a lifting outer component 22, and a fixing inner component 23. The fixing inner component 23 is securely fixed to the stage's base structure via a mounting bracket or similar structure, located between two floor assemblies 1. The fixing inner component 23 has a vertical through-cavity 231 machined inside, the lower end of which communicates with the main drainage pipe 3. The lifting outer component 22 slides around the fixing inner component 23 like a sleeve. Drainage outlets 221 are symmetrically provided on both side walls of the lifting outer component 22, and these outlets 221 communicate with the through-cavity 231 inside the fixing inner component 23.

[0023] The drive component 21 provides power to control the lifting and lowering of the lifting outer component 22. The drive component 21 can be a linear motor with a fixed cylinder. The end of its push rod is connected to the bottom of the lifting outer component 22, and the extension and retraction of the push rod directly drives the lifting outer component 22 to rise and fall. In another preferred embodiment, the drive component 21 may include a drive motor 211, a drive rack 212, and a drive connecting rod 213. The pinion at the output end of the drive motor 211 meshes with the drive rack 212, which slides horizontally on a guide rail. One end of the drive connecting rod 213 is hinged to the drive rack 212, and the other end is hinged to the bottom of the lifting outer component 22. When the drive motor 211 rotates forward, causing the drive rack 212 to move closer to the lifting outer component 22, the drive connecting rod 213 will lift upward, thereby pushing the lifting outer component 22 upward; conversely, it will drive the lifting outer component 22 downward. This linkage mechanism has a force-amplifying and self-locking effect, and operates stably.

[0024] To ensure smooth and non-rotating movement of the lifting outer component 22, a guide structure is provided. Specifically, a vertically arranged guide groove 4 is included, and a slider 222 (or roller) is fixed on the inner wall of the lifting outer component 22. The slider 222 is embedded in the guide groove 4, so that the lifting outer component 22 can only make strict up-and-down linear movements along the guide groove 4.

[0025] Sealing is crucial for protecting the stage's substructure. Therefore, a first seal (such as an O-ring or sealing bushing) is installed at the sliding fit between the fixed inner component 23 and the lifting outer component 22 to prevent water from seeping into the interior through this gap. Simultaneously, a second seal (such as a flexible rubber sealing strip) is installed at the contact point between the top of the lifting outer component 22 and the edge of the floor assembly 1. When the lifting outer component 22 descends to be flush with the floor, the second seal is pressed tightly, effectively preventing water from seeping down through the joint.

[0026] To further improve drainage efficiency, a negative pressure pump is connected and installed at the end of the main drainage pipe 3 or at a suitable location. When drainage is started, the negative pressure pump works synchronously, creating negative pressure (vacuum suction) in the main drainage pipe 3. This suction is transmitted to the drain outlet 221 through the passage cavity 231, which can actively "suck" the accumulated water into the drainage system, greatly accelerating the drainage speed.

[0027] Working principle: like Figure 2 As shown, in normal conditions: when there is no water accumulation on the stage, the drive unit 21 controls the lowering of the lifting outer component 22, so that its upper surface is flush with the upper surface of the floor assembly 1, and is sealed by the second sealing component. The entire stage is flat and seamless, making it easy to use.

[0028] like Figure 3As shown, in the drainage state: when water accumulates on the stage, the control system activates drive component 21 (and the negative pressure unit). Drive component 21 pushes the lifting outer component 22 upward, causing its top to protrude 5-30mm above the floor surface, forming a low weir. Simultaneously, the drain outlet 221 on the side of the lifting outer component 22 is fully exposed. Under the influence of gravity and the suction generated by the negative pressure unit, the accumulated water quickly enters through the drain outlet 221, flows through the cavity 231 of the fixed inner component 23, and finally flows into the main drain pipe 3 for discharge. Because the drain outlet 221 is located on the side and is concealed when not in use, blockages are effectively avoided.

[0029] The technical principles of this utility model have been described above with reference to specific embodiments. These descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, those skilled in the art can readily conceive of other specific embodiments of this utility model without inventive effort, and these embodiments will all fall within the protection scope of the claims of this utility model.
