[0024] Therefore, in order to ensure the use effect and achieve the purpose of the utility model, the following problems should be paid attention to in the production and installation of the protection equipment:

[0025] (1) on-site survey

[0026] Detailed on-site survey is conducted on the water wheel room to determine the installation path and fixed point position of the cable protection device. The structure layout of the water wheel room should be considered to avoid other equipment, pipelines and other obstacles. For example, a certain safety distance should be maintained from the relay oil pipe, top cover screw and the like to avoid mutual interference. At the same time, the space size of the installation point should be measured to ensure that the protection device can be smoothly installed.

[0027] (2) Cable protection device design

[0028] The cable protection device design of the present scheme is divided into two parts: top cover cable protection device and water guide cable protection device. The top cover cable protection device is a round device, and the water guide cable protection device is a round device and an irregular shaped cable protection channel.

[0029] (3) Main material of protection device

[0030] According to the requirements, select the appropriate size of stainless steel plate. Stainless steel has good strength and corrosion resistance to ensure the long-term stable use of the protection device in the water room environment. The present scheme uses 1.5mm thick stainless steel plate, which meets the requirements of cable laying and can also withstand possible external forces.

[0031] (4) Cutting and forming

[0032] According to the design size, use cutting equipment to cut the main material of the protection device. Ensure the size accuracy during cutting, and the error should be controlled within the allowable range. For example, for the cutting of straight line section protection device, the length error should not exceed ±5mm. After cutting the steel, perform forming processing, such as bending the steel plate into the required protection device shape through a bending machine, and the bending angle should be accurate. After forming, perform welding to ensure the splicing and installation accuracy of the protection device.

[0033] (5) Drilling

[0034] Drilling operation is performed at the connection parts of the protection device and the cable exit parts. The drilling position should be accurately determined according to the connection requirements and the cable exit position. The hole diameter of the drilling should meet the specifications of the connecting bolts, and the perpendicularity of the drilling should be guaranteed to avoid the skew phenomenon during bolt installation. According to the number of cables at the cable exit position, drill different size holes, and if necessary, reserve the hole.

[0035] (6) Connection components

[0036] Prepare enough number of stainless steel connecting bolts, nuts, washers, etc. For connecting bolts, their specifications should match the connection holes of the protection device and meet the strength requirements.

[0037] (7) Accessories

[0038] Prepare cable exit hole protection rubber gaskets and cable protection device legs that meet the requirements of different positions as needed, and their specifications and strength meet the requirements.

[0039] (8) Pre-installation

[0040] Install the processed cable protection device on the cross arm and horizontal support in sections. Use screws or other connectors to connect the sections together, ensuring firm connection. Adjust the position of the cable protection device to make it level and stable. Ensure that the protection device is firmly connected and does not loosen, such as misaligned connection holes, component deformation, etc. In particular, the ring-shaped protection device, whether it meets the measurement data, if there is a difference, modify it in time.

[0041] In summary, the utility model discloses simple structure, novel and unique, easy to use, easy to maintain, and can effectively prevent the interference of water wheel room environment to automatic components, guarantee use effect, improve work efficiency, have good social and economic benefits.
