Description

Technical Field

[0001] This utility model belongs to the field of safety protection technology, specifically relating to an intelligent linkage cover plate for a water turbine shaft. Background Technology

[0002] A shaft turbine, also known as a shaft-type axial-flow turbine generator, refers to an axial-flow turbine in which the generator is installed in a shaft leading into the plant. The shaft is usually equipped with a hoist for lifting and transporting personnel and materials. However, when the hoist moves downward, the shaft opening is open, and there is a risk that personnel and items may fall from the opening. There is currently no safety protection against falling from the opening.

[0003] Therefore, this application is hereby filed to disclose an installation device for wellhead protection in order to solve the above-mentioned problems. Summary of the Invention

[0004] The purpose of this utility model is to provide an intelligent control system that automatically opens and closes an intelligent linkage cover to prevent wellhead collapse.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A smart linkage cover plate for a turbine shaft includes a controller, a cover plate, and a slide rail. The slide rail is installed at the top of the shaft, and the cover plate is slidably connected to the slide rail. A drive device is installed on the cover plate and is drivenly connected to the slide rail. The controller is electrically connected to the drive device, and an infrared sensor electrically connected to the controller is installed on the inner wall of the shaft.

[0007] Furthermore, buffer blocks are provided on both sides of the slide rail.

[0008] The beneficial effects of this utility model are as follows:

[0009] Improved safety: By automatically blocking the well opening, personnel and objects are effectively prevented from falling from the well opening, greatly reducing the probability of safety accidents and ensuring the safety of personnel and equipment during the operation of the turbine shaft.

[0010] High degree of automation: It can automatically open and close according to the movement status of the lifting device without manual intervention, which improves work efficiency and reduces safety risks caused by human factors.

[0011] Real-time monitoring: Sensors enable real-time monitoring of the system's operating status, timely detection and alerts to abnormal situations, further improving the system's reliability and security.

[0012] The above description is only an overview of the technical solution of this utility model. In order to better understand the technical means of this utility model and to implement it in accordance with the contents of the specification, the preferred embodiments of this utility model are described in detail below with reference to the accompanying drawings. Attached Figure Description

[0013] Figure 1 This is a schematic diagram showing the opening state of the intelligent linkage cover plate of the turbine shaft according to an embodiment of the present invention;

[0014] Figure 2 This is a schematic diagram of the closed state of the intelligent linkage cover plate of the turbine shaft according to an embodiment of the present invention.

[0015] Attached diagram labels: 1. Shaft; 2. Infrared sensor; 3. Slide rail; 4. Cover plate; 5. Motor; 6. Buffer block. Detailed Implementation

[0016] The technical solution of this utility model will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0017] In the description of this utility model, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, 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 "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of 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] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0020] Please see Figure 1The intelligent linkage cover plate 4 of the turbine shaft 1 shown in a preferred embodiment of this application includes a controller, a cover plate 4 and a slide rail 3. The slide rail 3 is set on the top of the shaft 1, the cover plate 4 is slidably connected to the slide rail 3, and buffer blocks 6 are provided on both sides of the slide rail 3.

[0021] Specifically, a motor 5 is installed on the cover plate 4, and the cover plate 4 moves on the slide rail 3 via the motor 5. The motor 5 is electrically connected to the controller.

[0022] More specifically, an infrared sensor 2 electrically connected to the controller is installed on the inner wall of the shaft 1. When the elevator reaches the designated depth and triggers the infrared sensor 2, it sends a control command to the controller and controls the motor 5 to move the cover plate 4 to complete the opening and closing actions.

[0023] Working principle

[0024] When the elevator descends and the lifting platform reaches a designated depth that cannot be detected by the infrared sensor, a control command is sent to control the motor to drive the cover plate to close the well opening. When the elevator rises and the lifting platform reaches a designated depth and triggers the infrared sensor, a control command is sent to control the motor to drive the cover plate to open. There will be no interference, and the entire process is automatically controlled without human intervention.

[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0026] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the 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 all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
