Description

Technical Field

[0001] This invention relates to the field of single-wiping machine technology, specifically a heavy-duty single-wiping machine with self-cleaning function. Background Technology

[0002] In heavy-duty environments such as industrial workshops, large warehousing centers, and logistics parks, the ground often develops stubborn stains due to long-term exposure to heavy equipment and spilled materials (such as metal shavings, oil stains, and dust mixtures). Traditional cleaning equipment struggles to meet the demands for efficient cleaning.

[0003] Currently, heavy-duty floor cleaning largely relies on single-disc scrubbers. However, existing single-disc scrubbers generally suffer from the following problems: During cleaning, the brush discs of single-disc scrubbers easily accumulate oil, metal particles, dust, and other impurities, which continue to build up over time, leading to a significant decrease in cleaning efficiency. The nozzles of existing single-disc scrubbers are mostly designed with a fixed angle, causing the water jets to be thrown around due to centrifugal force, making it impossible to adjust the spray direction and intensity according to the actual level of contamination on the brush discs. When there is a thick buildup of impurities in certain areas of the brush disc, the fixed-angle water jets cannot accurately target the contaminated area, resulting in incomplete cleaning. Furthermore, the lack of real-time monitoring of the brush disc's working status makes it impossible to detect brush wear or impurity buildup in a timely manner, easily leading to fluctuations in cleaning quality. Summary of the Invention

[0004] The purpose of this invention is to provide a heavy-duty single-wiping machine with self-cleaning function to solve the problems mentioned in the prior art.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A heavy-duty single-function scrubber with self-cleaning function includes a handle, a water tank, transport wheels, a support rod, a drive motor, a brush disc, a connecting plate, a cleaning device, a detection device, and a high-pressure pump. The handle and support rod are fixedly connected; the support rod and water tank are fixedly connected; the support rod and connecting plate are fixedly connected; the connecting plate and transport wheels are rotatably connected; the drive motor is positioned above the connecting plate and is fixedly connected to the connecting plate; the cleaning device and brush disc are fixedly connected; the cleaning device and detection device are connected; the detection device and brush disc are connected; the output end of the drive motor passes through the connecting plate and brush disc and is fixedly connected; the connecting plate and brush disc are rotatably connected; the cleaning device and water tank are connected; the high-pressure pump and water tank are fixedly connected; the input end of the high-pressure pump is connected to the water tank via a pipe; and the high-pressure pump and cleaning device are connected.

[0007] The support rod serves as the main mounting base, providing installation positions for other devices. A counterweight on the connecting plate provides downward pressure. Workers control the overall movement of the device via a handle and transport wheels. Before starting work, clean water or cleaning agent must be placed in the water tank. The drive motor then outputs torque to rotate the brush disc, which cleans the ground. A high-pressure pump delivers water from the tank to the cleaning device, which then sprays water to remove dust and other impurities from the brush disc. A detection device measures the degree of dust adhesion on the brush disc and adjusts the cleaning angle accordingly to facilitate dust removal and improve cleaning efficiency.

[0008] Furthermore, the brush disc includes a mounting body and a brush. The mounting body is fastened to the output end of the drive motor. The mounting body is provided with a first mounting cavity and a second mounting cavity. A cleaning device is provided in the first mounting cavity, and a detection device is provided in the second mounting cavity. The tail end of the brush is placed in the second mounting cavity.

[0009] The mounting body serves as the primary mounting base for positioning other components. The first mounting cavity provides a base for the cleaning device, while the second mounting cavity provides a base for the detection device. A drive motor outputs torque to rotate the mounting body, which in turn rotates the brush. The brush repeatedly rubs against the ground, and a counterweight applies downward pressure to the mounting body, increasing the normal force between the brush and the ground, thus enhancing the brush's friction and improving its cleaning effect. Furthermore, multiple detection devices are provided for different cleaning devices, allowing each device to individually detect the brush in a specific area and simultaneously control the cleaning device in that area to clean the brush.

[0010] Furthermore, there are several second mounting cavities, which are evenly distributed on the bottom surface of the mounting body, and several first mounting cavities, which are distributed in a ring on the side wall of the mounting body.

[0011] Several brushes are provided on the mounting body, and the brushes are placed in the second mounting cavity. The number of brushes increases the cleaning effect. By arranging the first mounting cavities in a ring on the side wall of the mounting body, the cleaning device can clean the brushes without dead angles, thereby increasing the cleaning effect on the brushes.

[0012] Furthermore, the cleaning device includes a drive cylinder, a first rotary motor, a second rotary motor, and a high-pressure nozzle. The drive cylinder is fastened to the first mounting cavity, the first rotary motor is fastened to the output end of the drive cylinder, the second rotary motor is fastened to the output end of the first rotary motor, the output end of the second rotary motor is fastened to the high-pressure nozzle, and the high-pressure nozzle is connected to the output end of the high-pressure pump via a pipeline.

[0013] When the cleaning device needs to clean the brush, the drive cylinder outputs to move the first rotating motor, which in turn moves the second rotating motor. At the same time, the first rotating motor outputs torque to drive the second rotating motor to rotate, thereby moving the high-pressure nozzle to the working position. Then, the high-pressure pump sends water from the water tank into the high-pressure nozzle, which then sprays the water onto the brush to clean it.

[0014] Furthermore, the high-pressure nozzle is placed horizontally, and a second rotary motor is used to drive the high-pressure nozzle to rotate up and down.

[0015] Furthermore, the high-pressure nozzle sprays in the same direction as the brush disc rotates.

[0016] When the brush starts working, it rotates at high speed. The water jets from the horizontally placed high-pressure nozzles are sprayed along the direction of the brush's rotation, giving the water jets a horizontal velocity component in the same direction as the brush's rotation. When the water jets with an initial tangential velocity come into contact with the brush, the relative velocity difference between the two in the horizontal direction becomes very small. This avoids violent impact and is more like a gentle fusion. Once the water jets are integrated into the brush, the water droplets are also subject to centrifugal force. However, this centrifugal force no longer throws them off the brush plate, but instead presses them firmly against the roots of the bristles and the gap between the brush plate and the ground. Here, the centrifugal force becomes a positive driving pressure, helping the water jets to impact and break down stubborn dirt. This allows the water jets to overcome the drawback of being thrown away by centrifugal force in traditional vertical spraying methods.

[0017] Furthermore, the detection device includes a detection body, a detection spring, a connecting rope, a connecting plate, and a sliding rheostat. The detection body is provided with a third mounting cavity and a fourth mounting cavity. The tail end of the brush is placed in the third mounting cavity, and the tail end of the brush is fastened to the connecting rope. The detection spring, the connecting rope, the connecting plate, and the sliding rheostat are placed in the fourth mounting cavity. The end of the connecting rope away from the brush is fastened to the connecting plate, and the end of the connecting plate away from the connecting rope is fastened to the detection spring. The detection spring is fastened to the fourth mounting cavity. The sliding rheostat is connected to the connecting plate, and the sliding rheostat is electrically connected to the second rotating motor.

[0018] Furthermore, the connecting piece is used to change the resistance value of the sliding rheostat.

[0019] The detection body serves as the primary mounting base for positioning other components. When dust adheres to the brush and is not completely removed, the dust increases the brush's weight, causing it to tilt downwards during rotation. This causes the brush to rotate, and the brush tail end in the third mounting cavity deflects upwards, moving the connecting rope. This movement of the connecting rope moves the connecting plate, which in turn changes the resistance of the sliding rheostat. Simultaneously, the movement of the connecting plate causes the detection spring to recover its elastic potential energy. The greater the upward deflection angle of the brush tail end, the smaller the resistance of the sliding rheostat, and the greater the current output from the sliding rheostat to the second rotating motor. The second rotating motor simultaneously drives the high-pressure nozzle to rotate, allowing it to rotate in the direction of the brush deflection. This makes it easier for the water jet from the high-pressure nozzle to adhere to the brush, reducing the likelihood of the water jet failing to adhere to the brush due to the change in the force direction caused by the brush deflection, thus preventing the brush from cleaning dust and reducing its cleaning effectiveness.

[0020] Compared with the prior art, the beneficial effects of the present invention are:

[0021] 1. This invention features an independent cleaning device (including a drive cylinder, dual rotating motors, and a high-pressure nozzle). A high-pressure pump delivers water or cleaning agent from the water tank to the high-pressure nozzle. The nozzle is placed horizontally and sprays water along the direction of the brush disc's rotation, carrying a horizontal velocity component that is consistent with the direction of the brush disc's rotation. This allows for a "gentle blend" with the high-speed rotating brush disc, avoiding the drawback of water being flung away by centrifugal force during traditional vertical spraying. Simultaneously, centrifugal force is converted into "positive driving pressure," pressing the water flow towards the base of the bristles and the gaps in the ground, effectively breaking down stubborn impurities.

[0022] 2. The degree of contamination can be judged in real time by the change in the weight of the brush. When impurities are attached to the brush, the weight increases, causing the brush to tilt downward. Its tail end is pulled by the connecting rope to move the connecting plate, changing the resistance value of the sliding rheostat. At the same time, the change in resistance value is converted into a current signal, which controls the second rotating motor to adjust the angle of the high-pressure nozzle, so that the nozzle can always spray water along the tilt direction of the brush.

[0023] 3. The structure adopts a support rod and a connecting plate for fastening. A counterweight is added to the connecting plate to provide stable downward pressure, ensuring that the brush plate is in close contact with the ground under heavy load and avoiding shaking. At the same time, the mounting body of the brush plate fixes the cleaning device and the brush through multiple sets of mounting cavities (a first mounting cavity distributed in a ring and a second mounting cavity distributed evenly). The structural layout is balanced and can withstand high pressure friction and heavy load pressure, reducing component wear. Attached Figure Description

[0033] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0034] Example: Figures 1-8As shown, this invention provides a heavy-duty single-wiping machine with self-cleaning function, including a handle 1, a water tank 2, a transport wheel 3, a support rod 4, a drive motor 5, a brush disc 6, a connecting plate 7, a cleaning device 8, a detection device 9, and a high-pressure pump 10. The handle 1 and the support rod 4 are fixedly connected, the support rod 4 and the water tank 2 are fixedly connected, the support rod 4 and the connecting plate 7 are fixedly connected, the connecting plate 7 and the transport wheel 3 are rotatably connected, the drive motor 5 is placed above the connecting plate 7, the drive motor 5 and the connecting plate 7 are fixedly connected, the cleaning device 8 and the brush disc 6 are fixedly connected, the cleaning device 8 and the detection device 9 are connected, the detection device 9 and the brush disc 6 are connected, the output end of the drive motor 5 passes through the connecting plate 7 and the brush disc 6 and is fixedly connected, the connecting plate 7 and the brush disc 6 are rotatably connected, the cleaning device 8 is connected to the water tank 2, the high-pressure pump 10 is fixedly connected to the water tank 2, the input end of the high-pressure pump 10 is connected to the water tank 2 via a pipe, and the high-pressure pump 10 is connected to the cleaning device 8.

[0035] The support rod 4 serves as the main installation base, providing installation positions for other devices. The connecting plate 7 is equipped with a counterweight to provide downward pressure. The worker controls the overall movement direction of the device through the handle 1 and the transport wheel 3. Before starting work, clean water or cleaning agent needs to be placed in the water tank 2. Then, the drive motor 5 outputs torque to drive the brush plate 6 to rotate, and the brush plate 6 cleans the ground. The high-pressure pump 10 sends the water in the water tank 2 to the cleaning device 8, and then the cleaning device 8 sprays water to remove dust and other impurities from the brush plate 6. The detection device 9 detects the degree of dust adhesion on the brush plate 6, and then the detection device 9 adjusts the cleaning angle of the cleaning device 8 according to the degree of dust adhesion to facilitate the cleaning of dust on the brush plate 6 and improve the cleaning effect of the brush plate 6.

[0036] like Figures 1-7 As shown, the brush plate 6 includes a mounting body 61 and a brush 62. The mounting body 61 is fastened to the output end of the drive motor 5. The mounting body 61 is provided with a first mounting cavity 611 and a second mounting cavity 612. A cleaning device 8 is provided in the first mounting cavity 611, and a detection device 9 is provided in the second mounting cavity 612. The tail end of the brush 62 is placed in the second mounting cavity 612.

[0037] The mounting body 61 serves as the main mounting base for positioning other components. The first mounting cavity 611 provides a mounting base for the cleaning device 8, and the second mounting cavity 612 provides a mounting base for the detection device 9. The drive motor 5 outputs torque to rotate the mounting body 61, which in turn rotates the brush 62. The brush 62 repeatedly rubs against the ground, and a counterweight applies downward pressure to the mounting body 61, increasing the normal pressure between the brush 62 and the ground, thereby increasing the friction between the brush 62 and the ground and improving the cleaning effect of the brush 62. In addition, by setting up multiple sets of detection devices 9 corresponding to different cleaning devices 8, the detection device 9 can detect the brush 62 in a certain area and control the cleaning device 8 in that area to clean the brush 62.

[0038] like Figures 4-7 As shown, there are several second mounting cavities 612, which are evenly distributed on the bottom surface of the mounting body 61, and several first mounting cavities 611, which are distributed in a ring on the side wall of the mounting body 61.

[0039] Several brushes 62 are provided on the mounting body 61. Several brushes 62 are placed in the second mounting cavity 612 respectively. The cleaning effect is increased by the number of brushes 62. By arranging several first mounting cavities 611 in a ring on the side wall of the mounting body 61, the cleaning device 8 can clean the brushes 62 without dead angles, thereby increasing the cleaning effect of the brushes 62.

[0040] like Figures 5-7 As shown, the cleaning device 8 includes a drive cylinder 81, a first rotary motor 82, a second rotary motor 83, and a high-pressure nozzle 84. The drive cylinder 81 is fastened to the first mounting cavity 611, the first rotary motor 82 is fastened to the output end of the drive cylinder 81, the second rotary motor 83 is fastened to the output end of the first rotary motor 82, the output end of the second rotary motor 83 is fastened to the high-pressure nozzle 84, and the high-pressure nozzle 84 is connected to the output end of the high-pressure pump 10 via a pipeline.

[0041] When the cleaning device 8 needs to clean the brush 62, the drive cylinder 81 outputs to drive the first rotating motor 82 to move. The movement of the first rotating motor 82 drives the second rotating motor 83 to move. At the same time, the first rotating motor 82 outputs torque to drive the second rotating motor 83 to rotate, thereby moving the high-pressure nozzle 84 to the working position. Then, the high-pressure pump 10 sends water from the water tank 2 to the high-pressure nozzle 84, and then sprays it onto the brush 62 through the high-pressure nozzle 84, thereby cleaning the brush 62.

[0042] like Figures 5-7As shown, the high-pressure nozzle 84 is placed horizontally, and the second rotating motor 83 is used to drive the high-pressure nozzle 84 to rotate up and down.

[0043] The spray direction of the high-pressure nozzle 84 is the same as the rotation direction of the brush disc 6.

[0044] When the brush 62 starts working, it rotates at high speed. The water jet from the horizontally placed high-pressure nozzle 84 is sprayed along the rotation direction of the brush 62, giving the sprayed water a horizontal velocity component in the same direction as the brush 62's rotation. When the water jet with an initial tangential velocity contacts the brush 62, the relative velocity difference between the two in the horizontal direction becomes very small, which avoids violent impact and is more like a gentle fusion. Once the water jet is integrated into the brush 62, the water droplets are also subject to centrifugal force. However, this centrifugal force no longer throws them away from the brush plate 6, but instead presses them tightly against the roots of the bristles and the gap between the brush plate 6 and the ground. Here, the centrifugal force becomes a positive driving pressure, helping the water jet to impact and break down stubborn dirt. This allows the water jet to overcome the disadvantage of being thrown away by centrifugal force in traditional vertical spraying methods.

[0045] like Figure 6 and Figure 8 As shown, the detection device 9 includes a detection body 91, a detection spring 92, a connecting rope 93, a connecting piece 94, and a sliding rheostat 95. The detection body 91 is provided with a third mounting cavity 911 and a fourth mounting cavity 912. The tail end of the brush 62 is placed in the third mounting cavity 911, and the tail end of the brush 62 is fastened to the connecting rope 93. The detection spring 92, the connecting rope 93, the connecting piece 94, and the sliding rheostat 95 are placed in the fourth mounting cavity 912. The end of the connecting rope 93 away from the brush 62 is fastened to the connecting piece 94, and the end of the connecting piece 94 away from the connecting rope 93 is fastened to the detection spring 92. The detection spring 92 is fastened to the fourth mounting cavity 912. The sliding rheostat 95 is connected to the connecting piece 94, and the sliding rheostat 95 is electrically connected to the second rotating motor 83.

[0046] Connector 94 is used to change the resistance value of sliding rheostat 95.

[0047] The detection body 91 serves as the primary mounting base for positioning other components. When dust adheres to the brush 62 and is not completely removed, the dust causes the brush 62 to become heavier, tilting it downwards as it rotates. This changes the position of the brush's tail end, causing the tail end of the brush 62 within the third mounting cavity 911 to deflect upwards. This movement of the connecting rope 93 moves the connecting piece 94, which in turn changes the resistance of the sliding rheostat 95. Simultaneously, the movement of the connecting piece 94 causes the detection spring 92 to recover its elastic potential energy. The greater the upward deflection angle of the tail end of the brush 62, the smaller the resistance of the sliding rheostat 95. At the same time, the greater the current output by the sliding rheostat 95 to the second rotating motor 83, the second rotating motor 83 simultaneously drives the high-pressure nozzle 84 to rotate, so that the high-pressure nozzle 84 can rotate in the direction of the deflection of the brush 62. This makes it easier for the water sprayed by the high-pressure nozzle 84 to adhere to the brush 62, thereby reducing the possibility that the water cannot adhere to the brush 62 due to the change in the force direction of the water sprayed by the deflection of the brush 62, which would prevent the dust from being cleaned from the brush 62 and reduce the cleaning effect of the brush 62.

[0048] The working principle of this invention is as follows: Before starting work, clean water or cleaning agent needs to be placed in the water tank 2. Then, the drive motor 5 outputs torque to drive the brush disc 6 to rotate. When the brush 62 starts working, the brush 62 rotates at high speed. The water flow sprayed by the horizontally placed high-pressure nozzle 84 can spray along the rotation direction of the brush 62, so that the sprayed water flow itself has a horizontal velocity component in the same direction as the rotation direction of the brush 62. When the water flow with tangential initial velocity contacts the brush 62, the two are in the same horizontal direction. The speed difference becomes very small, which avoids violent impacts and is more like a gentle, flowing integration. Once the water flow merges with the brush 62, the water droplets are also subject to centrifugal force. However, this centrifugal force no longer throws them away from the brush disc 6, but instead presses them firmly against the roots of the bristles and the gap between the brush disc 6 and the ground. Here, the centrifugal force becomes a positive driving pressure, helping the water flow to impact and break down stubborn dirt. This allows the water flow to overcome the drawback of being thrown away by centrifugal force in traditional vertical jet methods. When the brush 62... If the dust adhering to the brush 62 is not completely cleaned, the dust increases its weight, causing the brush 62 to tilt downwards during rotation. This changes the position of the tail end of the brush 62, causing the tail end of the brush 62 in the third mounting cavity 911 to deflect upwards. This deflects the connecting rope 93, which in turn moves the connecting piece 94. The movement of the connecting piece 94 changes the resistance of the sliding rheostat 95, and simultaneously causes the detection spring 92 to recover its elastic potential energy. The greater the upward deflection angle of the tail end of the brush 62... The smaller the resistance of the sliding rheostat 95, the greater the current output by the sliding rheostat 95 to the second rotating motor 83. The second rotating motor 83 simultaneously drives the high-pressure nozzle 84 to rotate, so that the high-pressure nozzle 84 can rotate in the direction of the deflection of the brush 62. This makes it easier for the water sprayed by the high-pressure nozzle 84 to adhere to the brush 62, thereby reducing the water flow that cannot adhere to the brush 62 due to the change in the force direction of the sprayed water when the brush 62 deflects, which would prevent the dust from being cleaned from the brush 62 and reduce the cleaning effect of the brush 62.

[0049] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description.
