Description

Technical Field

[0001] The present application belongs to the technical field of protection of rotating equipment, and in particular, relates to a maintainable foundation pit device for rotating equipment. Background Art

[0002] Flywheel energy storage is a kind of physical energy storage. The motor drives the rotor to rotate at high speed, converting electrical energy into kinetic energy for storage. J represents the moment of inertia, ω represents the angular velocity. The flywheel rotor can only store more energy if it has a larger mass or rotation speed (the existing flywheel speed can reach tens of thousands of revolutions per minute and the weight can reach 10 tons). However, there are certain risks in the operation of high-speed and large-mass flywheels. In order to ensure the safety of personnel and equipment, such large flywheels are usually installed in pits. For large flywheels, the cost and workload of installation are very large. When a flywheel fails and needs maintenance or normal annual inspection, the cover of the pit needs to be lifted, and the flywheel needs to be lifted out of the pit to the maintenance area. After the maintenance, it needs to be lifted back for installation, which consumes a lot of labor and machinery costs. At the same time, the lifting operation also has a high risk. In addition, when the flywheel is installed in the pit, the flywheel is lower than the horizontal plane as a whole, which can easily cause rainwater to flow back and cause electrical accidents.

DETAILED DESCRIPTION

[0023] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0024] Before describing the various embodiments of the present application in detail, the technical concept of the present application is first briefly described: Currently, after the energy storage flywheel is installed in the foundation pit, it is necessary to lift the cover plate and lift the flywheel out of the foundation pit for later maintenance, and then lift it back into the foundation pit after the maintenance is completed. The maintenance process is relatively difficult. To this end, the maintainable foundation pit device for rotating equipment provided by the present application has a manhole on the cover plate, a maintenance channel on the installation base, and a maintenance through hole on the installation base plate. When performing maintenance, the maintenance personnel enter the foundation pit through the through hole, and then enter the maintenance channel and perform maintenance on the bottom of the rotating equipment through the maintenance through hole. In this way, there is no need to lift the cover plate and flywheel for maintenance, which greatly reduces the maintenance cost and difficulty. The specific principle of the maintainable foundation pit device for rotating equipment of the present application is described below in combination with more embodiments.

[0025] Specifically, Figure 1 , Figure 2 and Figure 3 As shown, this embodiment discloses a maintainable foundation pit device for rotating equipment, which includes a protective base 10 and a mounting base plate 20. The protective base 10 includes a mounting base 11, a protective wall 12 and a cover plate 13. The protective wall 12 is arranged around the edge of the mounting base 11, and the cover plate 13 is arranged on the top of the protective wall 12. The mounting base 11 is provided with a maintenance channel 14, and the cover plate 13 is provided with a manhole 15. The mounting base plate 20 is arranged on the mounting base 11 and spans the maintenance channel 14. The mounting base plate 20 is provided with a maintenance through hole 21, and the maintenance through hole 21 is located between the maintenance channel 14 and the bottom of the rotating equipment 100. Among them, the length, width and depth of the maintenance channel are based on the size that can accommodate maintenance personnel, and the size of the manhole 15 is based on the size that can pass maintenance personnel.

[0026] In one or more embodiments, a ladder 16 is provided on the inner side wall of the protective wall 12, and the top and bottom ends of the ladder 16 are respectively close to the manhole 15 and the maintenance channel 14, and the maintenance personnel enter the maintenance channel 14 through the ladder 16 after passing through the manhole 15. Exemplarily, there are two manholes 15 and two ladders 16, and the two ladders 16 are respectively provided on two opposite inner side walls of the protective wall 12, and the maintenance personnel can enter different sides of the maintenance channel 14 through different manholes 15 and different ladders 16.

[0027] Furthermore, if Figure 4As shown, the mounting base plate 20 is provided with a plurality of anchor bolt holes 22, the mounting base plate 20 is used to carry the rotating device 100, and the anchor bolt holes 22 are used to fix the rotating device 100 by bolt connection. Exemplarily, the plurality of anchor bolt holes 22 are arranged in two rows, distributed on opposite sides of the maintenance through hole 21, wherein the maintenance through hole 21 is distributed in the center of the mounting base plate 20.

[0028] Furthermore, a drainage pipe 17 is provided at the bottom of the maintenance channel 14 , and the drainage pipe 17 passes through the installation base. The maintenance channel 14 can also serve as a water storage tank, and the accumulated water and liquid are discharged to the outside through the drainage pipe 17 at the bottom.

[0029] Furthermore, the maintainable foundation pit device also includes a movable heat dissipation window (not shown), which is detachably mounted on the manhole 15, wherein the manhole 15 can also play a role in heat dissipation, and the movable heat dissipation window plays a waterproof role. When maintenance is required, the maintenance personnel can open the movable heat dissipation window and climb down from the manhole 15 along the ladder 16 to the inside of the protective matrix. Exemplarily, the number of movable heat dissipation windows is two. Among them, the movable heat dissipation window can be made of sheet metal, PVC material, tempered glass material, etc.

[0030] Furthermore, the outer edge portion of the top of the protective wall 12 is recessed to form a circle of mounting grooves 12a, and the bottom edge of the cover plate 13 is provided with a circle of protrusions 13a, and the protrusions 13a are located within the mounting grooves 12a. Through the cooperation between the mounting grooves 12a and the protrusions 13a, rainwater can be prevented from entering the interior of the protective base from the contact surface between the cover plate 13 and the protective wall 12.

[0031] Furthermore, if Figure 5 As shown, the top surface of the cover plate 13 is also provided with a plurality of lifting rings 13b, which are spaced apart at different positions of the cover plate 13. After the rotating device 100 is installed, the lifting equipment is used to connect the lifting rings 13b to lift the cover plate 13 and cover it on the top of the protective wall 12.

[0032] In one or more embodiments, the installation base 11 and the protective wall 12 are integrally formed reinforced concrete structures, the cover plate 13 is a reinforced concrete structure, and the protective base 10 is installed as a whole in the foundation pit.

[0033] The maintainable foundation pit device for rotating equipment provided in this embodiment allows maintenance personnel to enter the foundation pit through the through hole during maintenance, and then enter the maintenance communication and perform maintenance on the bottom of the rotating equipment through the maintenance through hole. This eliminates the need to lift the cover plate and flywheel for maintenance, greatly reducing maintenance costs and difficulty.
