[0004] It should be noted that the above introduction to the technical background is only for the convenience of providing a clear and complete description of the technical solutions of the present application and for the convenience of understanding by those skilled in the art. It cannot be considered that the above technical solutions are well known to those skilled in the art simply because they are described in the background technology section of the present application. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention provides a network room live cleaning robot for cleaning and maintenance of the network room. The device can automatically clean dust, impurities and dirt in the room, ensuring the cleanliness of the room environment and the normal operation of the equipment, effectively solving the problems of low cleaning efficiency of traditional manual cleaning rooms and safety risks for personnel in some potentially dangerous room environments.

[0006] In order to solve the above technical problems, the present invention specifically provides the following technical solutions: A live cleaning robot for a network room comprises a robot base, a motor module installed inside the robot base, and a driving wheel and a driven wheel arranged at the front and rear of the robot base. A cleaning blade is arranged on one side of the motor module, a steam generator is arranged on the top of the motor module, the steam generator is connected to a steam nozzle through a pipe body, and the steam nozzle is located on the top of the cleaning blade.

[0007] The driving wheel is arranged on the front side of the robot base and is driven by the motor module. The driving wheel is meshed with the motor driving shaft gear in the motor module. The central controller transmits a signal to the motor module to control the operation of the driving wheel. The rotation of the cleaning blade is also driven by the motor module. The water tank is located above the driving wheel. When the motor driving shaft in the motor module drives the driving wheel to rotate, heat is generated. The water tank arranged above can absorb this part of the heat in real time. The driven wheel does not participate in the driving and is freely arranged on the rear side of the robot base. A battery is arranged above the driven wheel. The steam generated by the steam generator is sprayed out by the steam nozzle.

[0008] From the overall structural point of view, this layout separates the electronic components and the steam generator through the dust box, so that the components that can generate heat are arranged near the water tank, and the water tank is used to dissipate heat and cool the heat-generating components. The dust box is adjacent to the steam generator, and the heat emitted by the steam generator can be used to dry out the moist impurities and gases that may be sucked into the dust box, thereby avoiding corrosion and odor in the dust box; the battery and sensor electronic components are arranged above the driven wheel on the other side to avoid excessive temperature affecting the safety of the battery and the normal operation of the sensor electronic components.

[0009] According to one embodiment of the present invention, the cleaning blades are composed of fan blades arranged in an array rotating around a central axis, the ends of the fan blades have a bending angle inward, a cleaning roller is provided on the side of the cleaning blades away from the motor module, and the cleaning blades and the cleaning roller are fixedly arranged in the middle section of the bottom of the robot base. A water tank is connected to one end of the steam generator, and the water tank is located above the driving wheel. A fan is provided at a distance away from the side of the steam nozzle away from the steam generator, and the fan is located above the cleaning roller, and the fan and the steam nozzle have the same horizontal height. A spacing distance is provided between the steam nozzle, the fan and the cleaning blades. A dust box is connected above the fan, and the dust box is located on one side of the steam generator. A temperature and humidity sensor is provided on the upper part of the central controller.

[0010] In the network room environment, dust is the main waste product. Due to the highly automated working mode of the network room, the flow of personnel in the room is not frequent, which leads to a lot of dust in the room that cannot be cleaned in time. There are many precision electronic components in the equipment in the room. Excessive dust accumulation may cause poor heat dissipation of the equipment and affect the working efficiency of the equipment. When the cleaning robot is working, it will run according to the established running route. The motor module drives the cleaning blades to rotate. The cleaning roller does not need to be driven. The fan assists the cleaning blades to suck dust and impurities into the dust box. The fan will also enhance the suction size and range of the cleaning blades.

[0011] The blades are arranged at an angle so that there are gaps between the blades, and the bottom gap between the two blades is smaller than the top gap. This dynamic design allows the gas to flow from the smaller part of the gap between the two blades to the larger part of the gap when the blades rotate, thereby generating an air vortex. Moreover, since the end of the cleaning blade is bent inward at an angle, the bending angle is between zero and ninety degrees, so that the angle between the bent part and the blade is not an acute angle. When the blade rotates, the bent part at the end of the blade will periodically disturb the surrounding air. This periodic disturbance causes the air to change in density, forming a series of pressure waves, that is, sound waves, which is a wave phenomenon caused by mechanical vibration. During the rotation process, this bent part is like a paddle, "cutting" and pushing the air. The rotation of the fan blades drives the surrounding air to move. The bent part causes the air to change direction and speed when it is pushed, causing local pressure changes. When the angle increases, the amount of air pushed per unit time increases, and the direction of the force on the air changes more significantly, which will lead to increased compression and rarefaction of the air, and an increase in the amplitude of the pressure wave generated, that is, an increase in the amplitude of the sound wave, so the sound emitted sounds louder. On the contrary, when the bending angle is small, the disturbance to the air is relatively weak, the amplitude of the air pressure change caused per unit time is small, the amplitude of the sound wave generated is small, and the sound emitted will also be relatively small. In addition, the higher the rotation speed, the higher the frequency of the sound wave generated at the same bending angle, and the louder the sound.

[0012] The air swirl generated when the blades rotate can solve the problem that the force driving the dust upward when the blades rotate is not concentrated, making the dust distribution more dispersed. This wind flow direction will also wash the fan blade body in real time when the fan blades rotate, which can prevent dust from adhering to the surface of the fan blades. In addition, the structure of the inward bending angle of the end of the fan blades will disturb the surrounding air when the blades rotate, causing the air to flow and vibrate, thereby generating sound waves. Since the bottom of the robot base is close to the bottom surface, and the horizontal height of the bottom of the elastic collar is lower than the horizontal height of the bottom of the robot base, a nearly closed space is formed between the robot base and the ground. After the fan blades rotate to generate sound waves, the sound waves are output to the ground and dispersed to the surroundings through the ground. Most of these sound waves will be transmitted from the gap between the bottom of the elastic collar and the ground, resulting in the transmission direction of the sound waves to the surroundings of the robot base. At the same time, this sound wave noise will have a repelling effect on some creatures, such as mice, and can prevent mice from gnawing on cables and affecting the operation of the equipment.

[0013] According to one embodiment of the present invention, a battery is provided above the driven wheel, a central controller and an infrared sensor are provided above the battery, and a plate partition is fixedly provided between the central controller and the infrared sensor.

[0014] If the operating temperature of the equipment in the computer room is too high, it may cause the equipment to freeze or be damaged. When the cleaning robot is working, it can scan the equipment in the computer room in real time while cleaning. The infrared sensor determines the equipment temperature through the infrared rays emitted by the equipment in the computer room. When it detects that the temperature of a certain device in the computer room is too high, it can alert the personnel to take manual measures. At the same time, after the robot determines that a person has entered the computer room, it can also enter a dormant state to avoid affecting the person's operation.

[0015] According to one embodiment of the present invention, an elastic ring is provided on the outside of the robot base, and a strip protrusion is provided on the inside of the elastic ring. The strip protrusion has an axial inclination angle with the elastic ring. The elastic ring is sleeved on the outside of the robot base, and the horizontal height of the bottom end of the elastic ring is lower than the bottom end height of the robot base.

[0016] The elastic collar has a buffering effect. On the one hand, the elastic collar can keep the robot in a balanced state and prevent it from tipping over. On the other hand, when the fan is blowing, since the inner side of the elastic collar is provided with a strip protrusion with an inclined angle to the axial direction of the elastic collar, the horizontal height of the bottom end of the elastic collar is lower than the height of the bottom end of the robot base, which will cause the airflow to disperse from the bottom of the robot base to the surroundings, and then be blocked by the bottom of the elastic collar. The airflow will go up along the strip protrusion inside the elastic collar. The airflow can blow off the dust attached to the robot base to avoid dust accumulation on the surface of the machine. In addition, since the strip protrusion is arranged obliquely, the airflow will have a certain rotational force when it goes up along the strip protrusion, which can avoid the situation of cleaning dead corners. At the same time, there are many ground cables in the machine room and they may be entangled. The horizontal height of the bottom end of the elastic collar is lower than the height of the bottom end of the robot base, which can exclude the ground cables from the outside of the robot to avoid stirring the ground cables into the cleaning robot.

[0017] Compared with the prior art, the present invention has the following beneficial effects: This arrangement separates the electronic components from the steam generator through the dust box, which can avoid the adverse effects of temperature on the robot to the greatest extent. The fan blade end of the cleaning blade is bent at an angle, which can solve the problem that the force of driving the dust upward when the blade rotates is not concentrated, making the dust distribution more dispersed. This wind flow direction can also prevent dust from adhering to the surface of the fan blade. When the blade rotates, sound waves will be generated. This sound wave noise will have a repelling effect on some creatures, such as mice, and can prevent mice from gnawing on the cables and affecting the operation of the equipment. The airflow moving upward along the inclined strip protrusions inside the elastic collar can blow off the dust attached to the robot base, avoid dust accumulation on the surface of the machine, and avoid the occurrence of cleaning dead corners. The dust box is adjacent to the steam generator, and the heat emitted by the steam generator can dry the moist impurities and gases that may be inhaled in the dust box, thereby avoiding the generation of odor in the dust box. The elastic collar can keep the robot in a balanced state, prevent it from tipping over, and also prevent the ground cables from being mixed into the cleaning robot.

The driving wheel 201 is meshed with the motor driving shaft gear in the motor module 203. The central controller 301 transmits a signal to the motor module 203 to control the operation of the driving wheel 201. The rotation of the cleaning blade 204 is also driven by the motor module 203. The water tank 100 is located above the driving wheel 201. When the motor driving shaft in the motor module 203 drives the driving wheel 201 to rotate, heat is generated.

A battery 30 is arranged above the driven wheel 202. The steam generated by the steam generator 101 is sprayed out by the steam nozzle 102.

[0025] From the overall structural point of view, the arrangement structure separates the electronic components from the steam generator 101 through the dust box 206, so that the components that can generate heat are arranged near the water tank 100, and the water tank 100 is used to dissipate heat and cool the heat-generating components. The dust box 206 is adjacent to the steam generator 101, and the heat emitted by the steam generator 101 can be used to dry out the moist impurities and gases that may be sucked into the dust box 206, thereby avoiding the generation of odor in the dust box 206; the battery 30 and sensor electronic components are arranged above the driven wheel 202 on the other side to avoid excessive temperature affecting the safety of the battery 30 and the normal operation of the sensor electronic components.

[0026] The cleaning blade 204 is composed of fan blades arranged in an array rotating around a central axis, and the end of the fan blade has a bending angle inward. A cleaning roller 207 is provided on the side of the cleaning blade 204 away from the motor module 203, and the cleaning blade 204 and the cleaning roller 207 are fixedly arranged at the middle section of the bottom of the robot base 10. A water tank 100 is connected to one end of the steam generator 101, and the water tank is located above the driving wheel 201. A fan 205 is provided at a distance away from the side of the steam nozzle 102 away from the steam generator 101, and the fan 205 is located above the cleaning roller 207, and the fan 205 is at the same level as the steam nozzle 102. A spacing distance is provided between the steam nozzle 102 and the fan 205 and the cleaning blade 204. A dust box 206 is connected above the fan 205, and the dust box 206 is located on one side of the steam generator 101. A temperature and humidity sensor 303 is provided on the upper part of the central controller 301.

[0027] In the network room environment, dust is the main waste product. Due to the high automation working mode of the network room, the flow of personnel in the room is not frequent, which leads to a lot of dust in the room that cannot be cleaned in time. There are many precision electronic components in the equipment in the room. Excessive dust accumulation may cause poor heat dissipation of the equipment and affect the working efficiency of the equipment. When the cleaning robot is working, the robot will run according to the established running route. The motor module 203 drives the cleaning blade 204 to rotate. The cleaning roller 207 does not need to be driven. The fan 205 assists the cleaning blade 204 to suck dust and impurities into the dust box 206. The fan 205 will also enhance the suction force and range of the cleaning blade 204. The blades are arranged at an angle so that there are gaps between the blades, and the bottom gap between the two blades is smaller than the top gap. This dynamic design allows the gas to flow from the smaller gap between the two blades to the larger gap when the blades rotate, thereby generating an air vortex, and the end of the cleaning blade 204 is bent inward at an angle, and the bending angle is between zero and ninety degrees, so that the angle between the bent part and the blade is not an acute angle. When the blade rotates, the bent part at the end of the blade will periodically disturb the surrounding air. This periodic disturbance causes the air to change in density, forming a series of pressure waves, that is, sound waves, which is a wave phenomenon caused by mechanical vibration. During the rotation process, this bent part is like a paddle, "cutting" and pushing the air. The rotation of the fan blades drives the surrounding air to move.

In addition, the higher the rotation speed, the higher the frequency of the sound wave generated at the same bending angle, and the louder the sound.

[0028] The air swirl generated when the blades rotate can solve the problem that the force of driving dust upward when the blades rotate is not concentrated, making the dust distribution more dispersed. This wind force flow direction will also wash the blade body in real time when the blades rotate, which can avoid the dust adhesion on the surface of the blades. And the structure of the inward bending angle of the blade end, when the blades rotate, the blade edge will disturb the surrounding air, causing the air to flow and vibrate, and then generate sound waves. Since the bottom of the robot base 10 is close to the bottom surface, and the horizontal height of the bottom of the elastic collar 305 is lower than the horizontal height of the bottom of the robot base 10, a nearly closed space is formed between the robot base 10 and the ground. After the blades rotate to generate sound waves, the sound waves are output to the ground and dispersed around through the ground. Most of these sound waves will be transmitted from the gap between the bottom of the elastic collar 305 and the ground, resulting in the transmission direction of the sound waves to the robot base 10. At the same time, this sound wave noise will have a repelling effect on some creatures, such as mice, and can prevent mice from gnawing cables and affecting the work of equipment.

[0029] A battery 30 is disposed above the driven wheel 202 , a central controller 301 and an infrared sensor 302 are disposed above the battery 30 , and a plate partition is fixedly disposed between the central controller 301 and the infrared sensor 302 .

[0030] If the operating temperature of the equipment in the computer room is too high, it may cause the equipment to freeze or be damaged. When the cleaning robot is working, it can scan the equipment in the computer room in real time while cleaning. The infrared sensor 302 determines the equipment temperature through the infrared rays emitted by the equipment in the computer room.

At the same time, after the robot determines that a person has entered the computer room, it can also enter a dormant state to avoid affecting the person's operation.

[0031] An elastic collar 305 is provided on the outside of the robot base 10, and a strip protrusion is provided on the inside of the elastic collar 305, and the strip protrusion has an inclined angle with the axial direction of the elastic collar 305. The elastic collar 305 is sleeved on the outside of the robot base 10, and the bottom level of the elastic collar 305 is lower than the bottom height of the robot base 10.

[0032] The elastic collar has a buffering effect. On the one hand, the elastic collar 305 can keep the robot in a balanced state and avoid rolling over. On the other hand, when the fan 205 is blowing, since the inner side of the elastic collar 305 is provided with a strip protrusion with an inclined angle to the axial direction of the elastic collar 305, the horizontal height of the bottom end of the elastic collar 305 is lower than the bottom end height of the robot base 10, which will cause the airflow to disperse from the bottom of the robot base 10 to the surroundings, and then be blocked by the bottom of the elastic collar 305. The airflow will go up along the strip protrusion inside the elastic collar 305, and the airflow can blow off the dust attached to the robot base 10 to avoid dust accumulation on the surface of the machine. In addition, since the strip protrusion is arranged obliquely, the airflow will have a certain rotation force when it goes up along the strip protrusion, which can avoid the situation of cleaning dead corners. At the same time, there are many ground cables in the machine room and they may be entangled. The horizontal height of the bottom end of the elastic collar 305 is lower than the bottom end height of the robot base 10, which can exclude the ground cables from the outside of the robot to avoid stirring the ground cables into the cleaning robot.
