[0002] During the maintenance of the turbine cover, the safety, reliability and portability of the protective device are crucial. They are not only related to the safety of the maintenance work, but also affect the quality and efficiency of the maintenance. The protective device must be installed firmly without shaking or displacement. On the premise of ensuring safety, the design of the protective device should take into account the convenience of maintenance work. For example, the guardrail should be easy to disassemble and install so that it can be easily moved or adjusted when necessary. In addition, the protective device should not affect the maintenance personnel's line of sight and operating space to avoid unnecessary interference with the maintenance work. The material of the protective device should have sufficient strength and durability to withstand the expected impact and pressure. At the same time, these materials should have good anti-slip and anti-corrosion properties to adapt to complex and changing working environments.

[0003] Traditional practices often rely on temporary shelters, such as tarpaulins, plastic films, etc. for covering; however, this simple protection method has the problem that the protection effect is not long-lasting: tarpaulins, plastic films and other materials are prone to aging and damage, and the protective performance gradually weakens over time, making it difficult to provide a sustained and stable protection effect.

[0004] In view of the above problems existing in the prior art, it is urgent to develop a highly efficient, durable, easy-to-disassemble and easy-to-assemble protective device specifically for the top cover of a hydropower unit. Summary of the invention

[0005] The technical problem to be solved by the utility model is to provide an external protective device for the top cover of a hydropower unit. The device decomposes the protective device into multiple modular and spliced ​​parts, that is, a circular guardrail is formed by enclosing multiple arc frames, which can achieve the purpose of easy installation and does not require the use of crane equipment for lifting, thereby greatly reducing the difficulty of installation; in addition, the device is relatively simple to disassemble, which is conducive to the storage and reuse of the device.

[0006] In order to solve the above technical problems, the technical solution adopted by the utility model is:

[0007] A hydroelectric generator set top cover outer protection device comprises a plurality of arc frames, on which transparent observation panels are detachably provided, two adjacent arc frames are connected by a connector, the plurality of arc frames enclose a circular guardrail, and a top plate is detachably provided on the top of the circular guardrail.

[0008] Preferably, the connecting piece comprises a flexible connecting belt installed on the edge of the arc-shaped frame, and the two flexible connecting belts are connected by a zipper.

[0009] Preferably, a window is provided on the arc-shaped frame, the top of the window is a hollow structure, a slot is provided at the edge of the window, and the transparent observation plate is inserted into the window through the slot.

[0010] Preferably, a pressure plate is provided on the top of the transparent observation plate, and the pressure plate is inserted into the slot.

[0011] Preferably, the top plate and the arc-shaped frame are connected by magnetic attraction.

[0012] The utility model can achieve the following beneficial effects:

[0013] 1. Multiple arc-shaped frames can be flexibly spliced ​​according to the contour of the actual hydropower unit top cover, ensuring that the protective device fits tightly with the top cover surface, providing comprehensive and accurate protective coverage, and effectively solving the problem of poor adaptability of traditional shelters.

[0014] 2. The setting of the transparent observation panel enables the operator to visually observe the internal maintenance status of the top cover without affecting the protection effect, which is convenient for daily inspections during maintenance and greatly enhances the convenience of operation and maintenance.

[0015] 3. Adjacent arc frames are connected by connectors, which realizes modular assembly of protective devices, which is convenient for transportation and on-site installation, simplifies disassembly and replacement during maintenance, and reduces overall maintenance costs.
