Description

Technical Field

[0001] The utility model relates to the technical field of electrical equipment protection, and more specifically to a falling protection shell for a distribution control box. Background Art

[0002] At present, the demand in the fields of energy, power transmission and transformation, electric vehicles, and industrial electricity is increasing. The distribution control box is used in various environments, mainly providing power control protection for equipment and indicating the working state of the power supply. During the use of the distribution control box, when the distribution control box falls, it may be damaged or the buttons may be accidentally touched, affecting electrical safety. Therefore, a falling protection shell for the distribution control box is needed.

[0003] After retrieval, the existing patent (publication number: CN219144820U) discloses a falling protection shell for a distribution control box. When the suspended distribution control box falls, it can effectively reduce the vibration intensity generated by the impact in all directions. The protection plate can contact the impact object prior to the control box, the anti-vibration base can disperse the vibration generated by the impact, the reinforcing column can stabilize the hollow protection shell, the hollow partition layer of the protection shell can play a buffering role during the impact, and the limit block can stabilize the internal distribution control box to prevent the distribution control box from colliding with the inner side of the protection shell. However, the inventor found the following problems in the process of implementing the present utility model: for the above-mentioned falling protection shell, a protection plate with a firm structure is arranged around the surface of the control box to prevent the screen and buttons of the control box from being touched. However, since the protection plate protrudes from the plane of the control box, it will cause a certain obstruction when the operator operates the control box. Moreover, since the protection plate is a rigid structure, when the protection plate falls downward, there is a lack of buffering effect between it and the control box, and the vibration during the fall will affect the safety of the control box.

[0004] In view of this, the present utility model proposes a falling protection shell for a distribution control box to solve these problems. Summary of the Utility Model

[0005] In order to overcome the above-mentioned defects of the prior art, the present utility model provides a falling protection shell for a distribution control box to solve the problems existing in the above background art.

[0007] The protection component includes a mounting strip fixedly installed at the top of the protection shell. The mounting strip has a notch reserved for the connection terminal. The height of the upper plane of the mounting strip is lower than the height of the upper surface of the control box body. A storage groove is formed at the top of the mounting strip, and a rubber airbag is arranged inside the storage groove. Inside the protection shell, a central controller, an air pipe, and an acceleration sensor are fixedly installed respectively.

[0008] Further, a silica gel shock-absorbing sleeve is coated on the outer wall of the protection shell; by setting the silica gel shock-absorbing sleeve, when the protection shell falls with the bottom end facing down, the silica gel shock-absorbing sleeve contacts the ground for buffering, so as to achieve the purpose of shock protection for the control box body.

[0009] Further, a pressure gauge is embedded at the bottom end of the protection shell, and the pressure gauge is communicated with the air pipe. A sealing plate is detachably installed at the bottom end of the protection shell corresponding to the mounting groove through bolts; by setting the pressure gauge, the internal air pressure of the compressed air tank can be monitored. When the air pressure is low, by opening the sealing plate and separating the compressed air tank from the threaded connector, the compressed air tank can be replaced.

[0010] Further, a hanging plate is fixedly connected to the top of the protection shell, and a hanging hole is formed on the surface of the hanging plate.

[0011] Further, a deflation valve is fixedly connected to the surface of the rubber airbag, and the deflation valve is embedded in the right side wall of the mounting strip; by setting the deflation valve, after the whole device falls, by opening the deflation valve, the gas inside the rubber airbag can be released, and the rubber airbag can be reinserted into the storage groove for storage.

The height of the upper plane of the installation strip 3 is lower than the height of the upper surface of the control box body 1. A storage groove is formed at the top of the installation strip 3, and a rubber airbag 4 is arranged inside the storage groove. Inside the protection shell 2, a central controller 5, an air pipe 6, and an acceleration sensor 7 are fixedly installed respectively. The air outlet end of the air pipe 6 is communicated with the rubber airbag 4. A solenoid valve 8 is arranged on the surface of the air pipe 6. The air inlet end of the air pipe 6 is fixedly connected with a threaded connector 9. At the bottom end of the protection shell 2, an installation groove is fixedly installed, and a compressed air tank 10 is arranged inside the installation groove. The compressed air tank 10 is communicated with the air pipe 6 through the threaded connector 9.

[0031] Further, when the control box body 1 drops during use, through the protection component, the acceleration sensor 7 detects the drop signal and transmits the drop signal to the central controller 5. The central controller 5 controls to open the solenoid valve 8. The gas inside the compressed air tank 10 can be injected into the rubber airbag 4 through the air pipe 6.
