Description

Technical Field

[0001] The present invention relates to the technical field of internal cleaning of substations, and particularly relates to a rake for cleaning silt and sundries during flood control in substations. Background Art

[0002] A substation is a power supply hub of the power system. When encountering bad weather such as heavy rain, it is extremely likely to lead to continuous heavy rainfall, and the resulting flood situation will pose a severe challenge to the safe operation of the power system. During the rainy season, timely drainage of the water outside the station can effectively avoid the situation of water entering the equipment site. Because water has strong penetration ability, if the water outside the substation is not drained in time, it will lead to a serious flood situation inside the station, thus endangering the safe and stable operation of the equipment inside the station.

[0003] The locations of some substations are low-lying and not conducive to water drainage. Screens or isolation nets are often installed at some water flow channels. Usually, these screens can play a filtering role, but during the flood season, the water flow is several times larger than usual, and sundries such as tree branches in the water are quickly blocked in front of the screens or isolation nets. These sundries quickly accumulate, which will seriously affect the water flow rate, and will lead to unthinkable extreme consequences such as water seepage in the cable trench inside the station, water overflowing the flood control dike, and even backflow into the equipment site.

[0004] Therefore, it is necessary to clean the sundries at the screens and filtering fences in time. At present, it is impossible to effectively clean the sundries at the screens and filtering fences. The existing tools are, firstly, ordinary rakes with short rake teeth that cannot hook the sundries; secondly, they have limited bearing capacity and cannot hook out the sundries under the impact of strong water flow; thirdly, they have limited length and cannot reach the sundries when the personnel stand in a safe position. In summary, all of these lead to low silt cleaning efficiency. It should be noted that during the flood season, the flood is merciless. Being able to quickly dredge the water channel and improve the silt cleaning efficiency will effectively resist the impact of the flood on the substation and ensure the safe and stable operation of the equipment inside the substation.

[0005] In summary, the existing rake has short rake teeth and cannot hook the sundries, has limited bearing capacity and cannot hook out the sundries under the impact of strong water flow, and has limited length and cannot reach the sundries when the personnel stand in a safe position, thus resulting in the problem of low cleaning efficiency. Summary of the Invention

[0006] In order to solve the problem that the existing rake has short rake teeth and cannot hook the sundries, has limited bearing capacity and cannot hook out the sundries under the impact of strong water flow, and has limited length and cannot reach the sundries when the personnel stand in a safe position, thus resulting in low cleaning efficiency, the present invention provides a rake for cleaning silt and sundries during flood control in substations.

[0007] A rake for cleaning silt and sundries during flood control in a substation, which comprises a rake hook 1, an internally threaded connecting pipe 2, a rod body 6 and a fixed cross beam 7;

[0008] A total of n rake hooks 1 are evenly arranged on the circumferential outer surface of the fixed cross beam 7 along the length direction, where n is a positive integer.

[0012] Furthermore, threaded sections are processed on the outer surfaces at both ends of the rod body 6;

[0013] Furthermore, the rake for cleaning silt and sundries during flood control in a substation further comprises an extension connecting sleeve 3, an extension rod body 5 and a hand pull handle 4;

[0014] One end of the rod body 6 is connected to one end of the extension rod body 5 through the extension connecting sleeve 3, and a hand pull handle 4 is provided at the other end of the extension rod body 5;

[0015] Furthermore, internal threads are processed on the inner wall of the extension connecting sleeve 3, and threaded sections are processed on the outer surfaces at both ends of the extension rod body 5;

[0016] Furthermore, a threaded hole is processed in the middle of the outer surface of the hand pull handle 4;

[0017] Furthermore, the hand pull handle 4 is threadedly connected to the other end of the extension rod body 5;

[0018] Furthermore, the extension connecting sleeve 3 is threadedly connected to one end of the extension rod body 5;

[0019] Furthermore, when in use, the operator stands in a safe area, holding the rake of the structure, and appropriately chooses whether to install the extension rod 5 according to the cleaning range or distance. After assembly, the silt and debris in front of the filter screen around the substation are cleaned. The J-shaped rake hook 1 can effectively hook the debris, and according to the cleaning environment, the bolts at the connection between each rake hook 1 and the fixed crossbeam 7 are loosened to adjust the angle of the rake hook 1, thereby improving the versatility of the device, thereby improving the dredging efficiency, timely dredging the waterway, preventing the water level outside the station from rising, and effectively resisting floods. Substation flood control work is directly related to the stability and safety of power supply. The degree of perfection of flood control measures and the effective use of flood control tools directly affect the disaster resistance and emergency response speed of the power grid. Effectively putting this invention into flood control work is of great significance to ensuring the flood control work of substations.

[0020] Compared with the prior art, the present invention has the following beneficial effects:

[0021] The present invention overcomes the shortcomings of the prior art. The J-shaped rake hook can effectively hook the debris, and according to the cleaning environment, the bolts at the connection between each rake hook and the fixed crossbeam are loosened to adjust the angle of the rake hook, thereby improving the versatility of the device. By adjusting the angle of the rake hook, the cleaning range is increased, thereby improving the cleaning efficiency, so that the water flow in the waterway is smooth, especially during the flood season, the debris blocked in the fence net and the waterway can be efficiently handled, which is safe and efficient. The water level of the waterway outside the substation is effectively controlled within the safe range, preventing the occurrence of situations such as flooding of the cable trench inside the station and backflow of the equipment site due to the blockage of the discharge outlet by debris outside the station. The importance of flood prevention work in substations cannot be ignored. It is directly related to the stability and safety of power supply and is an important basis for ensuring social and economic development and people's lives. Effectively putting this invention into flood prevention work is of great significance to ensuring flood prevention work in substations. It will effectively improve the flood prevention and disaster resistance capabilities and emergency response speed of substations. BRIEF DESCRIPTION OF THE DRAWINGS
