Description

Technical Field

[0001] The invention relates to the technical field of electromechanical devices, in particular to an electromechanical device with self-cleaning and heat dissipation. Background Art

[0002] Electromechanical equipment generally refers to machinery, electrical appliances and electrical automation equipment. The distribution box is a type of electromechanical equipment. The distribution box is a key electrical equipment, which is mainly responsible for power distribution, control and protection in the power system. It plays the role of distributing the power of the main line to various branches. It is also a key equipment to protect the safe and stable operation of electrical equipment. There are many electrical components such as relays, power switches, circuit breakers, etc. inside the distribution box.

[0003] The appearance of dust inside the distribution box is a relatively common phenomenon. There are many reasons for this. If the environment where the distribution box is located is dusty, such as near construction sites, factory workshops, roads, etc., then the dust concentration in the surrounding air will be relatively high, making it easier for dust to enter the distribution box. The electrical components in the distribution box will generate static electricity during operation. Static electricity has the characteristic of absorbing tiny particles, which makes it easy for dust in the surrounding air to be absorbed by the surface and corners of the electrical components inside the distribution box.

[0004] Distribution boxes are usually designed with vents on both sides. The vents can introduce fresh air to achieve heat exchange between the inside and outside air of the distribution box to achieve heat dissipation. When the distribution box is located in a low-lying area, the distribution box is easily soaked in water, which causes water to enter from the vents of the distribution box, causing the electrical components inside the distribution box to short-circuit and burn out when encountering water.

[0016] (III) Beneficial effects

[0017] The electromechanical device with self-cleaning and heat dissipation provided by the present invention has the following beneficial effects:

[0018] 1. The present invention uses a heat dissipation and dust removal component. The circulating fan sprays air and gas into the lower chamber inside the shell. The gas absorbs heat and is discharged from the exhaust grille, thereby achieving the effect of heat dissipation for the electrical components inside the shell. The gas passes through all the electrical components inside the shell from top to bottom and is discharged, effectively cooling the inside of the shell. The lifting motor drives the active roller to rotate, and the jet discharge sprays gas to the electrical components. The dust follows the gas and floats obliquely upward into the air. The dust collecting shell covers the floating dust. At the same time, the electrostatic adsorption cylinder rotates to adsorb and collect the dust, and the scraper scrapes the dust down to the dust collecting box to collect it inside, thereby achieving the effect of automatically cleaning and absorbing the dust on the surface of the electrical components inside the shell. The dust collecting shell covers the blown dust to prevent the dust from flying. The circulating fan sprays gas through the jet discharge to blow up the dust, and then recovers the gas through the intake pipe to form a cycle, so that the dust is continuously blown up and guided to the electrostatic adsorption cylinder to be adsorbed and collected. The dust collecting shell moves downward to clean the dust of all electrical components. Compared with the traditional cleaning by a vacuum cleaner, the jet discharge dissipates heat inside the shell and automatically cleans and collects the dust inside the shell, and the dust collection is convenient for subsequent processing.

[0019] 2. The present invention uses a sealing component. The electric telescopic rod drives the cone block to puncture the sealing plug. Carbon dioxide is sprayed toward the electrical components inside the housing through the jet exhaust. At the same time, the dust collecting shell drives the jet exhaust to move downward. The carbon dioxide sprayed by the jet exhaust cools all the electrical components. The housing is filled with carbon dioxide to avoid combustion caused by short circuit, high temperature and the like of the electrical components, thereby automatically preventing combustion from occurring inside the housing. Compared with the traditional gas fire extinguishing system, the jet exhaust sprays carbon dioxide close to the electrical components to effectively cool down and extinguish the fire. The movement of the jet exhaust ensures that all electrical components are flushed with the carbon dioxide airflow.

[0020] 3. The present invention uses a fire extinguishing component. Water enters from the exhaust grille of the distribution box, and the compressed sponge absorbs water and expands rapidly. The sealing plate moves downward to seal the exhaust grille. At the same time, the dust collecting shell moves to the outside of the sealing plate, so that the sealing plate is blocked by the dust collecting shell and cannot move. Therefore, the external water is blocked by the sealing plate and cannot pass through the exhaust grille, thereby achieving the effect of automatically sealing the exhaust grille when the water level exceeds the exhaust grille. Compared with the traditional distribution box, the device effectively blocks external water from entering the inside of the shell when the exhaust grille is submerged by water, thereby avoiding the situation where the electrical components inside the shell are short-circuited and burned due to water, and effectively protecting the safety inside the distribution box.

[0043] A card box 216 is fixedly connected inside the shell 1, and a sealing baffle 217 is slidably connected inside the card box 216. A support plate is arranged outside the sealing baffle 217, and the support plate is located on the top of the circulation fan 26. An air intake grille 218 is fixedly connected to the outside of the shell 1.

[0044] A sealing assembly for preventing electrical components inside the shell 1 from burning is provided inside the shell 1. The sealing assembly includes a carbon dioxide cylinder 31 fixedly connected to the top of the dust collecting shell 24. Carbon dioxide at a pressure of five to seven MPa is stored inside the carbon dioxide cylinder 31. An air guide cylinder 32 is fixedly connected to the outside of the carbon dioxide cylinder 31. The air guide cylinder 32 is connected to the air outlet pipe 27. A sealing plug 33 is provided at the air outlet of the carbon dioxide cylinder 31. The sealing plug 33 is made of rubber and can be punctured to allow the carbon dioxide inside the carbon dioxide cylinder 31 to leak. An electric telescopic rod 34 is slidably connected to the outside of the air guide cylinder 32. The electric telescopic rod 34 is externally connected to a temperature sensor. When the temperature sensor detects that the temperature inside the shell 1 is too high, it will control the electric telescopic rod 34 to extend. The electric telescopic rod 34 is fixedly connected to the dust collecting shell 24. A cone block 35 is fixedly connected to one end of the electric telescopic rod 34 close to the sealing plug 33. A venting groove is provided on the outside of the cone block 35.

[0045] The sealing assembly includes a sealing plate 41 slidably connected to the inside of the shell 1, and rubber rings are arranged around the sealing plate 41 to increase air tightness. A sliding block 42 is fixedly connected to the top of the sealing plate 41, and the sliding block 42 is slidably connected to the inside of the shell 1. An exhaust grille 43 is fixedly connected to the outside of the shell 1. The bottom of the sealing plate 41 is rotatably connected to a support rod 44, and a compressed sponge 45 is fixedly connected to the inside of the shell 1. The compressed sponge 45 will expand rapidly when absorbing water, and an oblique clamping block 46 is fixedly connected to the top of the compressed sponge 45. The top inclined surface of the oblique clamping block 46 is provided with an arc-shaped protrusion, and the oblique clamping block 46 is clamped with the support rod 44.

[0046] The following is the entire working process and working principle of the above embodiment: the user turns on the circulation fan 26, the circulation fan 26 draws air through the air inlet pipe 29, the outside air enters the upper chamber of the shell 1 through the air inlet grille 218, the gas passes through the top of the air guide inclined plate 213 and passes through the dust screen 210 to be absorbed into the air inlet pipe 29, the circulation fan 26 inputs the air through the air outlet pipe 27 to the inside of the jet exhaust 28 fixedly connected thereto, because the jet exhaust 28 is located in the lower chamber inside the shell 1, the jet exhaust 28 sprays the gas into the lower chamber inside the shell 1, the gas moves from top to bottom, absorbs the heat generated by the working of the electrical components inside the shell 1 and discharges it from the exhaust grille 43, achieving the effect of heat dissipation for the electrical components inside the shell 1, and the gas is discharged from the exhaust grille 43. The dust collecting shell 24 is driven by the stabilizing pulley 25 connected to the dust collecting shell 24, and the stabilizing pulley 25 is driven by the stabilizing pulley 25. The stabilizing pulley 25 and the stabilizing pulley 25 are ... The gas will spray obliquely upward toward the electrical components inside the lower chamber of the shell 1, and the gas will rebound obliquely upward when it contacts the electrical components. The dust on the surface of the electrical components will float obliquely upward into the air with the gas. Since the dust collecting shell 24 is located outside the jet row 28, the dust collecting shell 24 will cover the floating dust. At the same time, the circulating fan 26 draws air through the air inlet pipe 29. Therefore, the air inlet pipe 29 generates suction through the dust screening net 210, so that the suspended dust covered by the dust collecting shell 24 moves toward the dust screening net 210. Since an electrostatic generator is provided inside the electrostatic adsorption cylinder 211, the outer side of the electrostatic adsorption cylinder 211 is provided with electrostatically adsorbed dust. The floating dust is adsorbed on the surface by the electrostatic adsorption cylinder 211, and the dust screening net 210 filters the dust to prevent the dust from entering the air inlet pipe 29. The surface of the dust-proof net 210 will fall downward to the surface of the electrostatic adsorption cylinder 211 and be adsorbed. At the same time, the dust collecting shell 24 moves downward, driving the rotating roller 212 connected thereto to move downward. The rotating roller 212 rotates due to friction with the transmission belt 23. The rotating roller 212 rotates, driving the electrostatic adsorption cylinder 211 fixed thereto to rotate, so that the surface of the electrostatic adsorption cylinder 211 adsorbs dust evenly. The rotation of the electrostatic adsorption cylinder 211 causes the fixed scraper 214 to scrape off the thick layer of dust adsorbed by the electrostatic adsorption cylinder 211, so that the dust falls downward to the inside of the dust collecting box 215 and is collected, thereby achieving the effect of automatically cleaning and absorbing the dust on the surface of the electrical components inside the outer shell 1. The dust collecting shell 24 covers the blown dust to prevent the dust from flying.The circulating fan 26 blows up the dust through the air jet 28, and then recovers the gas through the air inlet pipe 29 to form a cycle, so that the dust is continuously blown up and guided to the electrostatic adsorption cylinder 211 to be adsorbed and collected. The dust collecting shell 24 moves downward to clean the dust of all electrical components. Compared with the traditional cleaning by vacuum cleaner, the air jet 28 dissipates heat inside the shell 1 and automatically cleans and collects the dust inside the shell 1, and the dust collection is convenient for subsequent processing.

[0047] Furthermore, when the temperature sensor connected to the electric telescopic rod 34 detects that the temperature inside the shell 1 is too high, the electric telescopic rod 34 will be controlled to extend. The electric telescopic rod 34 drives the cone block 35 fixedly connected thereto to move toward the sealing plug 33. The cone block 35 punctures the sealing plug 33, causing the carbon dioxide inside the carbon dioxide cylinder 31 to be ejected, and the carbon dioxide enters the outlet pipe 27 through the gas guide tube 32 and is sprayed toward the electrical components inside the shell 1 through the jet exhaust 28. At the same time, the output shaft of the lifting motor 21 drives the active roller 22 to rotate the transmission belt 23, and the transmission belt 23 drives the dust collecting shell 24 to move downward. The downward movement of the dust collecting shell 24 drives the jet exhaust 28 to move downward. The carbon dioxide ejected from the jet exhaust 28 cools down all the electrical components, and the inside of the shell 1 is filled with carbon dioxide to prevent the electrical components from short-circuiting, high temperature, and other situations and causing combustion, thereby achieving the effect of automatically preventing combustion from occurring inside the shell 1. Compared with the traditional gas fire extinguishing system, the jet exhaust 28 sprays carbon dioxide close to the electrical components to effectively cool down and extinguish the fire of the electrical components. The movement of the jet exhaust 28 allows all electrical components to be flushed with the carbon dioxide airflow.

[0048] Furthermore, when the distribution box is located in a low-lying area, the distribution box is easily soaked in water, which causes water to enter from the exhaust grille 43 of the distribution box. When the compressed sponge 45 located inside the shell 1 is wetted by water, the compressed sponge 45 absorbs water and expands rapidly. The compressed sponge 45 drives the oblique clamping block 46 fixedly connected thereto to move upward, and the top inclined surface of the oblique clamping block 46 pushes the support rod 44 to move outward, so that the arc-shaped protrusion on the top of the oblique clamping block 46 is separated from the support rod 44. Therefore, the sealing plate 41 loses the support of the support rod 44, and the sealing plate 41 moves downward due to the influence of gravity. The sealing plate 41 drives the sliding block 42 fixedly connected thereto to slide downward inside the shell 1, and the sealing plate 41 moves to The downward movement seals the exhaust grille 43, and at the same time, the output shaft of the lifting motor 21 drives the active roller 22 to rotate the transmission belt 23, and the transmission belt 23 drives the dust collecting shell 24 to move downward, and the dust collecting shell 24 moves to the outside of the sealing plate 41, so that the sealing plate 41 is blocked by the dust collecting shell 24 and cannot move. Therefore, the external water is blocked by the sealing plate 41 and cannot pass through the exhaust grille 43, so that the exhaust grille 43 is automatically sealed when the water level exceeds the exhaust grille 43. Compared with the traditional distribution box, the device effectively blocks the external water from entering the inside of the shell 1 when the exhaust grille 43 is submerged by water, thereby avoiding the situation where the electrical components inside the shell 1 are short-circuited and burned due to water, and effectively protecting the safety inside the distribution box.
