Description

Technical Field

[0001] The invention belongs to the technical field of self-leveling floor construction, and in particular relates to a self-leveling floor grinding and dust reduction device and method. Background Art

[0002] Cement-based self-leveling floor materials have been widely used in various types of construction due to their good flatness and decorative effects, especially in the construction of substations that require high ground flatness. However, the construction process of self-leveling floors, especially the ground grinding stage, will generate a large amount of dust that is difficult to control. This dust not only seriously reduces the environmental quality of the construction site and indoors, increases the health risks of construction workers, but also affects the final quality and aesthetics of the floor because the dust adheres to the surface of the self-leveling material that has not been fully cured. In addition, the spread of dust also leads to a decrease in construction efficiency, increases the difficulty and cost of subsequent cleaning and maintenance, and brings unnecessary troubles to the long-term operation and maintenance of the substation.

[0003] The self-leveling floor grinders currently used in the market have improved the grinding efficiency to a certain extent, but the amount of dust generated during the operation is still huge. In order to protect the health of construction workers, construction workers usually wear dust masks when working, which not only increases the inconvenience of construction, but also affects work efficiency. And because the large amount of dust released during the grinding process is difficult to settle quickly, it often takes up to a day to carry out indoor dust reduction after construction, which not only prolongs the construction period, but also increases the overall construction cost.

[0011] In a possible implementation of the first aspect, the sprinkler mechanism also includes a water level monitoring module arranged in the water tank, and the water level monitoring module is used to monitor the water level in the water tank. The control module is also used to control the working state of the self-leveling floor grinder body according to the water level and a set water level threshold value. When the water level is lower than the water level threshold value, the self-leveling floor grinder body is controlled to stop grinding.

[0012] In a possible implementation of the first aspect, the sprinkler mechanism further includes a water volume warning module, which is electrically connected to the control module, and when the water volume is lower than the water volume threshold, the control module is also used to control the water volume warning module to issue a warning.

The combination of water sprinkling and dust suction greatly reduces the amount of dust on the construction site, thereby improving the construction environment and reducing the health risks faced by construction workers due to long-term exposure to high-concentration dust environments. The synergistic effect of the dust concentration collection module and the control module enables the dust suction mechanism and the water sprinkling mechanism to automatically adjust the working state according to the real-time dust concentration. When the dust concentration exceeds the preset first concentration threshold, the two mechanisms are immediately started and enter the dust reduction working state, effectively avoiding dust from adhering to the surface of the self-leveling material that is not fully cured, and ensuring the final quality of the ground. In addition, due to the reduction in the amount of dust, the dust reduction treatment time after construction is also greatly shortened, thereby improving the overall construction efficiency.

DETAILED DESCRIPTION

[0025] In order to make the purpose, technical solution and advantages of the embodiments of the present invention clearer, the technical solution of the present invention will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0026] like Figure 1 As shown, an embodiment of the present invention provides a self-leveling floor grinding and dust reduction device, the purpose of which is to fundamentally solve the dust problem generated during the self-leveling floor grinding process, improve construction efficiency, protect the health of construction personnel, and reduce the cost of subsequent cleaning and maintenance. The self-leveling floor grinding and dust reduction device includes a self-leveling floor grinder body 1, a dust suction mechanism 2, a water sprinkling mechanism 3, a dust concentration collection module 4 and a control module 5. The dust suction mechanism 2 is arranged on the self-leveling floor grinder body 1, and the dust suction port of the dust suction mechanism 2 faces the ground; the water sprinkling mechanism 3 is arranged on the self-leveling floor grinder body 1; the dust concentration collection module 4 is arranged on the dust suction mechanism 2, and the dust concentration collection module is used to collect dust concentration; the control module 5 is used to control the working state of the dust suction mechanism 2 and the water sprinkling mechanism 3 according to the dust concentration and the set first dust concentration threshold value. When the dust concentration exceeds the first dust concentration threshold value, the dust suction mechanism 2 and the water sprinkling mechanism 3 are controlled to enter the working state.

[0027] Specifically, the self-leveling floor grinder body 1 adopts a common structure in the prior art, including but not limited to a motor drive system, a grinding disc and a grinding disc drive mechanism. The self-leveling floor grinder body 1 is movable, which is convenient for flexible operation in different construction areas. It should be understood that the grinding disc is made of a wear-resistant material with moderate hardness to ensure the dual needs of grinding efficiency and floor flatness. The dust suction mechanism 2 is integrated below or on the side of the self-leveling floor grinder body 1, and the dust suction port is close to the grinding disc to ensure that the dust generated by grinding can be sucked away in time. It should be noted that the dust suction mechanism 2 is internally configured with a filter assembly, which can effectively separate dust and air to avoid secondary pollution. The watering mechanism 3 is arranged on the grinder body 1, and illustratively, water mist can be evenly sprayed on the grinding area through a micro-spray or atomizing nozzle.

[0028] The dust concentration collection module 4 is installed near the dust suction port of the dust suction mechanism 2 or in the dust suction duct, and uses the optical or weight method to monitor the dust concentration in real time. The data collected by the dust concentration collection module 4 is transmitted to the control module 5. The control module 5 is responsible for receiving the data of the dust concentration collection module 4 and performing logical judgment according to the preset first dust concentration threshold. When the dust concentration exceeds the first dust concentration threshold, the control module 5 automatically starts the dust suction mechanism 2 and the water sprinkling mechanism 3 and enters the dust reduction working mode. It should be noted that the control module 5 also has a manual control function, allowing construction personnel to flexibly adjust the intensity of dust suction and water sprinkling according to the actual situation on site. For example, the first dust concentration threshold can be set to 1mg / m 3 .

[0029] More specifically, when the self-leveling floor grinding and dust reduction device of this embodiment is used for grinding operation, the construction personnel start the self-leveling floor grinding machine body 1 and start the grinding operation. The dust concentration collection module 4 monitors the dust concentration generated during the grinding process in real time and sends the data to the control module 5. When the dust concentration exceeds the set first dust concentration threshold, the control module 5 automatically activates the dust suction mechanism 2 and the water sprinkling mechanism 3 to start the dust reduction operation. The dust suction mechanism 2 efficiently sucks away the dust in the air, while the water sprinkling mechanism 3 sprays water mist to moisten the ground and further suppress the flying of dust. Of course, the construction personnel can also adjust the intensity of dust suction and water sprinkling through the manual control function of the control module 5 according to the actual situation on site to achieve the best dust reduction effect. After the grinding operation is completed, the self-leveling floor grinding machine body 1 is turned off, and the dust suction mechanism 2 and the water sprinkling mechanism 3 continue to work for a period of time to ensure that all dust is completely removed. Afterwards, clean the dust box and water tank to prepare for the next operation.

[0030] It can be seen that the synergistic effect of the dust suction mechanism 2 and the water sprinkling mechanism 3 effectively reduces the amount of dust generated during the grinding process, ensuring the air quality at the construction site. Automatic dust reduction reduces the time for construction workers to manually reduce dust, speeds up the construction progress, reduces the risk of construction workers getting sick due to inhaling dust, improves the comfort of the working environment, reduces the amount of cleaning work after construction, and reduces the overall construction cost. In summary, the self-leveling floor grinding and dust reduction device provided by the present invention, by integrating dust suction, water sprinkling and intelligent control functions, realizes effective control of dust during the grinding process, while also reducing the number of machines on the construction site, providing an efficient and environmentally friendly solution for the construction of substations.

[0031] In one possible implementation, Figure 1 As shown, the self-leveling floor grinding and dust reduction device also includes a battery pack 6, which is arranged on the self-leveling floor grinding machine body 1, and the battery pack 6 is used to supply power to the dust suction mechanism 2, the water sprinkling mechanism 3, the dust concentration collection module 4 and the control module 5.

[0032] That is to say, the battery pack 6 serves as the main power source of the entire self-leveling floor grinding and dust reduction device, and is responsible for providing a stable and continuous power supply to the dust collection mechanism 2, the watering mechanism 3, the dust concentration collection module 4 and the control module 5, so that the device can work independently without an external power supply, which greatly improves the flexibility of use. It should be noted that the battery pack 6 can be installed inside or outside the self-leveling floor grinding machine body 1 in a position that is easy to connect and does not affect the operation.

[0033] Preferably, before starting the self-leveling floor grinder body 1, the control module 5 will first check the power status of the battery pack 6. If the power is lower than the preset safety threshold, a warning will be issued, and it is recommended to charge or replace the battery pack to ensure the smooth operation process. During the operation, the control module 5 will intelligently adjust the power consumption of each module according to the actual needs of the dust collection mechanism 2, the watering mechanism 3 and the dust concentration collection module 4 to maximize the battery efficiency. For example, when the dust concentration is low, the power of the dust collection mechanism can be appropriately reduced to reduce energy consumption.

[0034] In this embodiment, the use of battery power completely solves the problem of power cord dragging, which not only avoids the risk of tripping at the construction site, but also eliminates safety hazards such as electric shock, providing a safer working environment for construction workers. At the same time, no external power supply is required, so that the self-leveling floor grinding and dust reduction device can be moved to any construction site without being restricted by power supply, greatly improving the flexibility of construction.

[0035] In one possible implementation, Figure 1 As shown, the dust collection mechanism 2 includes a dust collection box 20 arranged at the front end of the self-leveling floor grinder body 1, and a dust collection motor 21 connected to the dust collection box 20, and the dust collection motor 21 is electrically connected to the control module 5.

[0036] Specifically, the dust suction motor 21 is installed at the rear of the dust box 20, and is connected to the inside of the dust box 20 through a sealed duct to form a negative pressure dust suction system. Exemplarily, the dust suction motor 21 uses a high-speed, low-noise model to ensure that while providing strong suction, it reduces noise interference during work. The power cord of the dust suction motor 21 is directly connected to the control module 5. Through the intelligent regulation of the control module 5, the speed and power of the dust suction motor can be adjusted according to the actual needs of the grinding operation to achieve energy-saving and efficient dust collection. Exemplarily, a filter assembly is provided inside the dust box 20, including a primary filter and a high-efficiency HEPA filter, which can capture and separate tiny particles in the air to ensure that the exhausted air is clean and pollution-free.

[0037] Preferably, the dust collection mechanism 2 further includes a dust collection amount monitoring module disposed in the dust collection box 20, and the dust collection amount monitoring module is used to monitor the dust collection amount in the dust collection box 20. The control module 5 is also used to control the working state of the self-leveling floor grinder body 1 according to the dust collection amount and the set dust collection amount threshold value, and when the dust collection amount exceeds the dust collection amount threshold value, the self-leveling floor grinder body 1 is controlled to stop grinding. Exemplarily, the dust collection amount threshold value can be set to 90%.

[0038] Specifically, the control module 5 can receive data from the dust collection monitoring module and, based on preset logical judgment conditions, perform real-time control on the working state of the self-leveling floor grinder body 1. When the dust collection reaches or exceeds the set threshold, the control module 5 will immediately send a stop command to the self-leveling floor grinder body 1, waiting for the operator to clean the dust box 20 in time. It should be noted that the control module 5 also has a manual reset function. When the dust box 20 is cleaned and reinstalled, the operator can manually reset the state of the dust collection monitoring module to restore the normal operation of the self-leveling floor grinder body 1.

[0039] In this embodiment, the coordinated work of the dust collection monitoring module and the control module not only improves the degree of automation of the self-leveling floor grinding and dust reduction device, but also effectively avoids dust overflow and environmental pollution, ensuring the efficiency, safety and environmental protection of the grinding operation.

[0040] In one implementable manner, the dust collection mechanism 2 further includes a dust collection amount warning module, which is electrically connected to the control module 5. When the dust collection amount exceeds a dust collection amount threshold, the control module 5 is also used to control the dust collection amount warning module to issue a warning.

[0041] Specifically, the dust collection amount warning module and the control module 5 are electrically connected to realize data transmission and command reception. For example, the dust collection amount warning module integrates an acoustic and optical alarm device, including a high-brightness LED indicator and a buzzer, which can send an intuitive warning signal to the operator when the dust collection amount reaches or exceeds a preset threshold.

[0042] The triggering logic of the dust volume warning signal is as follows: the dust volume monitoring module detects the dust accumulation in the dust box 20 in real time and sends the data to the control module 5. The control module 5 compares the dust volume with the preset dust volume threshold. Once the dust volume exceeds the dust volume threshold, the control module 5 immediately sends a warning instruction to the dust volume warning module. After receiving the warning instruction, the dust volume warning module immediately starts the warning program, the LED indicator light flashes red or orange, and the buzzer emits a continuous or intermittent alarm sound. The warning signals work together to ensure that the attention of operators can be effectively attracted in a noisy construction environment.

[0043] It can be seen that in this embodiment, the dust collection amount warning module improves the safety of the self-leveling floor grinding and dust reduction device. Through timely warning signals, operators can respond and take necessary cleaning measures to effectively avoid dust overflow.

[0044] In one possible implementation, Figure 1 As shown, the sprinkler mechanism 3 includes a water tank 30 arranged at the front end of the self-leveling floor grinder body 1, and a plurality of spray modules 31 installed on the water tank 30. The plurality of spray modules 31 are located near the top of the water tank 30, and the spray modules 31 are electrically connected to the control module 5.

[0045] Specifically, the spray module 31 is the executive component of the water spray mechanism 3. The spray module 31 adopts a nozzle design, which can produce fine and uniform water mist, effectively reducing the dust generated during the grinding process. During the operation, the control module 5 will intelligently adjust the injection pressure and flow rate of the spray module 31 according to the moving speed of the self-leveling floor grinder body 1 and the actual situation of the grinding area, ensuring that the water mist and the grinding operation are carried out synchronously to achieve the best dust reduction effect. Preferably, the water tank 30 is also equipped with a visual water level indicator, which is convenient for the operator to check the water volume at any time.

[0046] In an achievable manner, the watering mechanism 3 further includes a water volume monitoring module disposed in the water tank 30, the water volume monitoring module is used to monitor the water volume in the water tank 30, and the control module 5 is further used to control the working state of the self-leveling floor grinder body 1 according to the water volume and the set water volume threshold value, and when the water volume is lower than the water volume threshold value, the self-leveling floor grinder body 1 is controlled to stop grinding. Exemplarily, the water volume threshold value can be set to 5%.

[0047] Specifically, when the water volume is lower than the set water volume threshold, the control module 5 will immediately receive an alarm signal from the water volume monitoring module. The control module 5 sends a shutdown command to the self-leveling floor grinder body 1, waiting for the operator to replenish the water volume. The water volume monitoring module improves the automation level of the self-leveling floor grinding dust reduction device and ensures the continuous stability of the watering operation.

[0048] It should be noted that the water volume threshold is set according to the spraying capacity of the sprinkler mechanism 3 and the actual demand of the self-leveling floor grinding operation, with the purpose of ensuring that the dust reduction operation is carried out when there is sufficient water.

[0049] In one achievable manner, the sprinkler mechanism 3 further includes a water volume warning module, which is electrically connected to the control module 5. When the water volume is lower than the water volume threshold, the control module 5 is also used to control the water volume warning module to issue a warning.

[0050] Specifically, the water volume warning module integrates a high-brightness LED indicator and a buzzer. After receiving the warning instruction from the control module 5, the water volume warning module immediately starts and sends out a warning signal. The LED indicator will flash red or orange, and the buzzer will send out a continuous or intermittent alarm sound.

[0051] The triggering logic of the water volume warning signal is as follows: the water volume monitoring module monitors the water volume in the water tank 30 in real time and sends the data to the control module 5. The control module 5 compares the water volume with the preset water volume threshold. Once the water volume is lower than the water volume threshold, the control module 5 immediately sends a warning instruction to the water volume warning module and simultaneously triggers a shutdown instruction to stop the grinding machine. After receiving the warning instruction, the water volume warning module starts the warning program, and the LED indicator light and the buzzer work together, and the warning signal continues to be issued until the operator replenishes the water and manually cancels the warning.

[0052] In one implementable manner, the control module 5 is also used to control the working state of the self-leveling floor grinder body 1 according to the dust concentration and the set second dust concentration threshold. When the dust concentration exceeds the second dust concentration threshold, the self-leveling floor grinder body 1 is controlled to stop grinding, wherein the second dust concentration threshold is greater than the first dust concentration threshold.

[0053] Specifically, when the dust concentration continues to rise and exceeds the second dust concentration threshold, it indicates that the current dust reduction measures are no longer sufficient to effectively control the dust concentration. At this time, the control module 5 will immediately trigger a shutdown command to stop the self-leveling floor grinder body 1 from grinding to avoid excessive dust concentration from damaging the working environment and personnel health. When the dust concentration is reduced to a safe range, the operator can manually cancel the shutdown command to resume normal operation of the self-leveling floor grinder body 1.

[0054] For example, the second dust concentration threshold can be set to 10 mg / m 3 .

[0055] In one possible implementation, the control module 5 is further provided with a touch display panel 7. On the touch display panel 7, the operator can view the working status of the dust suppression device in real time, including the spraying status of the sprinkler mechanism 3, the water volume of the water tank 30, and the dust concentration data provided by the dust concentration monitoring module. In addition to viewing the information, the operator can also perform various settings and adjustments on the dust suppression device through the touch display panel 7. For example, the spraying frequency and intensity of the sprinkler mechanism 3 can be set, the threshold of the dust concentration can be adjusted, and the conditions for automatic shutdown or alarm can be set.

[0056] The embodiment of the present invention also provides a self-leveling floor grinding dust reduction method, which adopts the self-leveling floor grinding dust reduction device in the above embodiment, and the dust reduction method is: the operator starts the self-leveling floor grinding machine body 1 and starts the floor grinding operation. The dust concentration collection module 4 starts to collect the dust concentration of the working area in real time and sends the data to the control module 5. When the dust concentration exceeds the set dust first concentration threshold, the control module immediately controls the dust suction mechanism 2 and the water sprinkling mechanism 3 to enter the working state. The dust suction motor 21 is started, and the dust collecting box 20 starts to collect dust; at the same time, the spraying module 31 starts to spray water mist to suppress the flying of dust. As the grinding operation continues, the dust concentration may continue to increase. When the dust concentration exceeds the set dust second concentration threshold (greater than the dust first concentration threshold), the control module 5 will trigger a shutdown command to stop the self-leveling floor grinding machine body 1 from grinding to prevent the excessive dust concentration from causing adverse effects on the working environment and personnel health. During the dust collection process, the dust collection amount monitoring module monitors the dust collection amount in the dust collecting box 20 in real time. When the dust volume exceeds the set dust volume threshold, the control module 5 will control the self-leveling floor grinder body 1 to stop grinding, and send out a warning signal through the dust volume warning module to remind the operator to clean the dust box. At the same time, the water volume monitoring module monitors the water volume in the water tank in real time. When the water volume is lower than the set water volume threshold, the control module 5 will control the self-leveling floor grinder body 1 to stop grinding, and send out a warning signal through the water volume warning module to remind the operator to add water. When the grinding operation is completed, the operator turns off the self-leveling floor grinder body 1 and cleans the dust box 20, the water tank 30 and other components.

[0057] In one embodiment, if Figure 2 As shown, a topology example of a battery pack 6 power supply circuit is provided, which is mainly composed of a battery unit, a BOOST boost circuit, an inverter and a permanent magnet synchronous motor, wherein u dc is the battery voltage, L dc For energy storage inductor, C dc is the voltage stabilizing capacitor, S dc , S1-S6 are power electronic switch devices, D dc The BOOST circuit increases the voltage of the battery from low voltage to high voltage and stabilizes the voltage through capacitors. The inverter uses space vector control method to output three-phase sinusoidal voltage to drive the motor.

[0058] In one embodiment, if Figure 3As shown, a block diagram of the control part of the dust collection mechanism is provided.

The battery provides a DC power supply for the entire circuit; the BOOST circuit is a boost circuit responsible for increasing the battery voltage; the inverter function is to convert DC power into three-phase AC power; the PMSM is a permanent magnet synchronous motor that can efficiently convert electrical energy into mechanical energy and suck dust into the dust collection box. The control part is mainly composed of a 3s / 2r coordinate transformation, a flux observer, two PI regulators, a 2r / 3s coordinate transformation and a SVPWM modulator.

[0059] In one embodiment, if Figure 4 As shown, the water sprinkling and dust reduction uses a neural network algorithm to control the water volume of each water sprinkling port according to the dust concentration, dust suction motor speed and dust humidity detection data. The neural network algorithm simulates the intuitive thinking mode of the human brain and can effectively solve the nonlinear system optimization problem. The algorithm sets the input layer, hidden layer and output layer. The target optimization performance parameter is usually used as the input layer, and the control object control parameter is used as the output layer. The hidden layer is used to simulate the human brain's nonlinear problem solving process. In order to effectively reduce the dust concentration and avoid the dust suction motor and other drive motors from stalling, the dust concentration, dust suction motor speed, dust suction motor dust humidity and other drive motor dust humidity related to the parameters are set as input layer parameters. For example, the water volume of the four spraying modules is the output layer parameter. According to the parameter quantity, 5 hidden layer functions are used. The hidden layer function is obtained by training the neural network algorithm with a large amount of data. This method can reduce the difficulty of parameter setting and accurately calculate the water volume of each water sprinkling port in real time. The water sprinkling and dust reduction effect is obvious and the occurrence of motor stalling is greatly reduced.
