Description

Technical Field

[0001] The utility model relates to the technical field of cleaning equipment, in particular to an equipment cleaning device for power engineering. Background Art

[0002] Power equipment primarily falls into two categories: power generation equipment and power supply equipment. Power generation equipment primarily includes power station boilers, steam turbines, gas turbines, hydro turbines, generators, transformers, and more. Power supply equipment primarily includes transmission lines of various voltage levels, transformers, contactors, and more. Power engineering equipment encompasses a variety of equipment used for power generation, transmission, distribution, and power system monitoring, including but not limited to power generation equipment, transmission equipment, distribution equipment, power electronics equipment, and monitoring equipment. These devices play a vital role in power engineering, ensuring the stable and efficient transmission and supply of electrical energy. Over time, the surfaces of these devices absorb a certain amount of dust, necessitating regular cleaning.

[0003] Based on the above, the following problems were found: the current cleaning methods for power equipment are generally manual wiping or low-pressure flushing. Manual wiping relies on manpower to clean the surface of the equipment one by one. For large power equipment such as transformers, insulator strings, etc., it takes a lot of time and manpower, and it is difficult to meet the rapid maintenance needs of batch equipment; the water flow of low-pressure flushing has weak impact force, and the effect of removing stubborn dirt such as dirt on the surface of insulators is poor. Repeated flushing is often required, further reducing efficiency.

[0004] Therefore, in view of this, the existing structure and defects are studied and improved, and a cleaning device for power engineering equipment is provided to achieve the purpose of having more practical value. Utility Model Content

[0005] The purpose of the present utility model is to provide a cleaning device for electric power engineering equipment to solve the problems raised in the above background technology.

[0006] In view of the above problems, the technical solution proposed by the present invention is:

[0007] A device for cleaning equipment for power engineering, comprising a connecting assembly, a jet pipe, a switching assembly and a nozzle assembly; the connecting assembly comprises a hose, one end of which is externally mounted with a flange, and the hose is flange-connected to the liquid outlet end of a high-pressure pump at the end on which the flange is mounted; the jet pipe comprises a pipe body, one end of which is fixedly connected to the end of the hose away from the flange, a throat section is provided at the inner center of the pipe body, an inlet section and a diffuser section are respectively provided inside the pipe body on both sides of the throat section, the inlet section is close to the hose, and the diffuser section is away from the hose; the switching assembly comprises a Y-shaped tee pipe, the liquid inlet end of the Y-shaped tee pipe is fixedly connected to the end of the pipe body close to the diffuser section, the two liquid outlet ends of the Y-shaped tee pipe are respectively connected to a first branch pipe and a second branch pipe, and the first branch pipe and the second branch pipe are respectively connected to a first connecting pipe and a second connecting pipe at the end away from the Y-shaped tee pipe; the nozzle assembly comprises a first nozzle and a second nozzle, the first nozzle is fixedly connected to the end of the first connecting pipe away from the first branch pipe, and the second nozzle is fixedly connected to the end of the second connecting pipe away from the second branch pipe.

[0008] Furthermore, the inner diameter of the inlet section decreases continuously from the end of the tube body close to the hose to the center, and the inner diameter of the diffusion section decreases continuously from the end of the tube body away from the hose to the center.

[0009] The beneficial effect of adopting the above-mentioned further scheme is that the inner diameter of the inlet section gradually decreases from the end close to the hose to the center (throat section), so that the flow velocity of the fluid increases steadily after entering from the hose, and the pressure energy is efficiently converted into kinetic energy, forming a high-speed jet in the throat section, enhancing the impact force of the jet, and providing sufficient kinetic energy for subsequent cleaning; the inner diameter of the diffusion section gradually decreases from the end farthest from the hose to the center (throat section), which can guide the high-speed jet to transition smoothly, reduce the turbulence and energy loss of the fluid in the pipe, ensure that the jet enters the Y-shaped tee in a stable state, avoid the diversion effect affected by flow velocity fluctuations, and improve the overall jet efficiency.

[0010] Furthermore, the length of the first branch pipe is greater than that of the second branch pipe, the hose, jet pipe, Y-shaped tee pipe, first branch pipe and second branch pipe are connected, the first branch pipe is connected to the first connecting pipe, and the second branch pipe is connected to the second connecting pipe.

When the high-pressure jet liquid enters the first nozzle through the first branch pipe and is then sprayed out from the first spray hole, since the length of the first branch pipe is greater than that of the second branch pipe, the second nozzle will not interfere with the water flow sprayed by the first nozzle.

[0012] Furthermore, the middle parts of the first connecting tube and the second connecting tube are spherical, and the first spherical seat and the second spherical seat are rotatably connected at the internal centers of the first connecting tube and the second connecting tube respectively.

[0014] Furthermore, the outer walls of the first connecting tube and the second connecting tube are both installed with hollow seats, the inner top ends of the two hollow seats are both installed with servo motors, and the output ends of the two servo motors are respectively connected to the first spherical seat and the second spherical seat.

[0015] The beneficial effect of adopting the above further solution is that by providing two servo motors, the two servo motors respectively drive the first spherical seat and the second spherical seat to rotate.

[0016] Furthermore, a plurality of heat dissipation fins are installed on the outer walls of the two hollow seats, one end of each of the heat dissipation fins passes through the hollow seat and extends to the interior, and the heat dissipation fins are made of one of brass and copper.

[0017] The beneficial effect of adopting the above further scheme is that through the setting of heat dissipation fins, the material of the heat dissipation fins is selected from one of brass and copper, brass or copper has excellent thermal conductivity, and the heat dissipation fins pass through the inside and outside of the hollow seat, which can quickly conduct the heat generated by the servo motor when it is working to the outside world, thereby avoiding performance degradation or damage to the servo motor due to high temperature.

[0018] Furthermore, the first nozzle is connected to the first connecting pipe, the second nozzle is connected to the second connecting pipe, the outer wall of the first nozzle is provided with a plurality of first spray holes, and the second nozzle is provided with a plurality of second spray holes at the end away from the second connecting pipe.

[0019] The beneficial effect of adopting the above-mentioned further scheme is that the spray holes on the outer wall of the first nozzle can realize lateral and multi-angle spraying, which is suitable for cleaning the circumferential surface of the equipment (such as cylindrical insulators); the spray holes at the end of the second nozzle can realize forward direct injection, which is suitable for cleaning the plane or vertical parts of the equipment (such as pipe openings, equipment tops); the combination of the two spraying methods eliminates cleaning dead corners and improves the comprehensiveness of cleaning.

[0020] Compared with the prior art, the beneficial effects of the present invention are as follows: the equipment cleaning device for power engineering, through the arrangement of a hose and a flange, connects one end of the hose provided with a flange to the flange of the liquid outlet end of the high-pressure pump, the high-pressure pump pressurizes the fluid, and the high-pressure fluid (water, etc.) enters from the inlet section, and the inner diameter of the inlet section gradually decreases from the end close to the hose to the center (throat section), the fluid flow rate begins to increase, and the pressure decreases; when it reaches the throat section, the flow rate reaches a peak and the pressure drops to a minimum; then in the diffusion section, the flow rate gradually decreases and the pressure rebounds; finally, the high-speed fluid is ejected from the jet tube outlet to form a jet with a strong impact force, and then passes through the Y-shaped tee, the first branch pipe, the first connecting pipe, the first spherical seat and the flow channel aligned with the liquid inlet and outlet of the first connecting pipe, and finally is ejected by the first nozzle, thereby realizing jet cleaning.
