Description
Technical Field
[0001] The utility model relates to the technical field of water engineering equipment, and particularly relates to a control system for a cleaning machine. Background Art
[0002] In water engineering, in order to efficiently clean the dirt in the water channel, a cleaning machine is generally arranged at the water inlet of the water channel.
[0003] However, since the motion system (such as a driving motor) of the existing cleaning machine (such as a rotary cleaning machine) is generally controlled by strong electricity, if the cleaning machine has been in an operating (power-on) state without anyone on duty, it will not only pose a safety hazard to equipment management, but also consume a relatively large amount of electricity.
[0004] However, if manual labor is arranged to monitor the operation of the cleaning machine, on the one hand, it will result in high labor costs, and on the other hand, it may also cause a large amount of dirt to accumulate due to the failure to handle the dirt in time, resulting in the rotary cleaning machine having difficulty in operating or even being damaged due to overload. Summary of the Utility Model
[0005] In order to solve at least one of the foregoing problems, according to one aspect of the present utility model, a control system for a cleaning machine is provided.
[0006] The control system for the cleaning machine includes a dirt detection and control module, which is used to issue a first control signal according to the situation of the dirt on the cleaning machine to control the cleaning machine to be connected to a first power supply, or issue a second control signal to control the cleaning machine to be disconnected from the first power supply; a second power supply, which is a weak electricity power supply and is used to supply power to the dirt detection and control module; wherein, the first power supply is a strong electricity power supply.
[0007] Thus, the cleaning machine does not need to be continuously in an operating state. For example, when the dirt detection and control module detects that the dirt on the cleaning machine (such as on the grid body of the cleaning machine) does not reach the level that needs to be cleaned, the cleaning machine does not need to be in an operating state; only when the dirt detection and control module detects that the dirt on the cleaning machine needs to be cleaned, it issues a first control signal to control the cleaning machine to start operating (connected to the strong electricity power supply); thereby, the cleaning machine does not need to be continuously connected to the strong electricity power supply, and since the dirt detection and control module is powered by the weak electricity power supply, it is possible to realize the automatic start (the cleaning machine is connected to the strong electricity power supply) and stop (the cleaning machine is disconnected from the strong electricity power supply) of the cleaning machine without continuous power supply by the strong electricity power supply and without anyone on duty for the cleaning machine.
[0008] In some embodiments, the dirt detection control module includes a detection module and a first control module; wherein the detection module is used to detect the water level conditions upstream and downstream of the garbage cleaning machine, and generate a first detection signal to send to the first control module; the first control module determines the condition of the dirt on the garbage cleaning machine according to the first detection signal, and sends a first control signal to control the garbage cleaning machine to be connected to the first power supply or sends a second control signal to control the garbage cleaning machine to be disconnected from the first power supply.
[0009] By detecting the water level conditions upstream and downstream of the garbage cleaning machine to determine the condition of the dirt on the garbage cleaning machine, it is possible to monitor the condition of the dirt on the garbage cleaning machine in real time, quickly determine whether the garbage cleaning machine is blocked by dirt, and improve the cleaning efficiency; it is also convenient for the integrated setting of the detection module in the water treatment facility; in addition, since water level monitoring is not limited by the type and size of dirt, the detection module can be applied to more types of environments and conditions, has stronger environmental adaptability and applicability, and is easier to expand to more monitoring points.
[0010] In some embodiments, the detection module includes: a first water level sensor, which is arranged upstream of the garbage cleaning machine and is used to detect the water level condition upstream of the garbage cleaning machine; and a second water level sensor, which is arranged downstream of the garbage cleaning machine and is used to detect the water level condition downstream of the garbage cleaning machine.
[0011] Thus, the first control module can obtain the difference between the upstream and downstream water levels through the upstream water level detected by the first water level sensor and the downstream water level detected by the second water level sensor, and obtain the water level conditions upstream and downstream of the garbage cleaning machine and the conditions of the dirt on the garbage cleaning machine; moreover, compared with other equipment for detecting water levels, the use of water level sensors to detect water levels has high detection accuracy, can provide a variety of signal output options, is suitable for different liquids such as clean water, sewage, corrosive liquids, etc., has strong applicability, is easy to install and maintain, has good stability, has a high protection level, has strong anti-interference ability (such as anti-electromagnetic interference), has high reliability, long service life, low cost and other beneficial effects.
[0012] In some embodiments, the first water level sensor and the second water level sensor are arranged in pairs. Thus, the first control module can obtain the difference between the upstream and downstream water levels through the upstream water level detected by the first water level sensor and the downstream water level detected by the second water level sensor.
[0013] In some embodiments, the first water level sensor is arranged upstream of the grid body of the garbage cleaning machine; the second water level sensor is arranged downstream of the grid body of the garbage cleaning machine; thus, the water level difference detected by the water level sensors upstream and downstream of the grid body can be used to judge whether the dirt on the grid body has reached the level that needs to be cleaned, so as to improve the detection accuracy of the water level sensor.
[0014] In some embodiments, the first water level sensor and the second water level sensor are arranged in the measuring hole of the gate pier. The water level sensor is arranged in the measuring hole of the gate pier, which can prevent the water level sensor from being directly exposed to water flow scouring or the external environment, reducing the risk of damage to the water level sensor; ensuring that the water level sensor can be stably installed, preventing the water level sensor from moving or tilting due to water flow fluctuations, reducing the interference of water surface fluctuations, floating objects, aquatic plants, etc. on the water level sensor readings, reducing the maintenance frequency of the water level sensor, improving the detection accuracy of the water level sensor, improving the continuity of water level sensor data detection, and facilitating regular calibration and maintenance of the water level sensor.
[0015] In some embodiments, the weak power supply is a power supply with a voltage lower than 24V. Since the power supply for the dirt detection control module is a low-voltage power supply lower than 24V, the safety of the module operation can be ensured; moreover, since the power supply for the dirt detection control module is a weak power supply, even if the dirt detection control module is powered continuously, high energy consumption will not be generated; at the same time, since the voltage and current of the weak power supply are small, the risk of damage to sensitive electronic equipment can be reduced, the interference to signal transmission and electromagnetic can be reduced, and the heat generated during the operation process is less, which helps to reduce heat loss; in addition, since the power cable of the weak power supply is generally thinner, it is convenient for wiring and installation of the power cable, which helps to reduce the occupation of space.
[0016] In some embodiments, the weak power source is a solar cell or a storage battery. Selecting a solar cell as the weak power source can save energy consumption; selecting a solar cell or a storage battery as the weak power source can also achieve stable power supply to the dirt detection control module.
[0017] In some embodiments, the dirt detection control module further includes a first time relay, which is preset with a first delay time; the first time relay is configured such that, when the dirt detection control module sends a first control signal, the first time relay disconnects the dirt cleaning machine from the first power supply for a first delay time, and then connects the dirt cleaning machine to the first power supply. Thus, when the actual water level difference between the upstream and downstream is greater than the set water level difference, the dirt cleaning machine can be connected to the first power supply after the first delay time, so as to avoid the dirt cleaning machine from being started by mistake due to the water level difference caused by the waves.
[0018] In some embodiments, the waste detection control module is further configured to control the waste conveying device to be connected to the first power source when it issues the first control signal; the waste detection control module also includes a second time relay, which is preset with a second delay time; the second time relay is configured to disconnect the waste conveying device from the first power source after the second time relay keeps the waste conveying device connected to the first power source for the second delay time when the waste cleaning machine is disconnected from the first power source. Thus, when the waste cleaning machine stops running, the waste conveying device will also transport the waste unloaded by the waste cleaning machine to a place away from the waste cleaning machine to avoid the accumulation of waste near the waste cleaning machine.

[0028] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0029] Figure 1 The control system of the garbage cleaning machine 30 according to one embodiment of the present invention is schematically shown.
[0030] like Figure 1As shown, the control system of the garbage cleaning machine 30 includes a first water level sensor 211, a second water level sensor 212, a first control module 22, and a second power supply 42. The first water level sensor 211 is arranged upstream of the garbage cleaning machine 30, and is used to detect the water level upstream of the garbage cleaning machine 30. The second water level sensor 212 is arranged downstream of the garbage cleaning machine 30, and is used to detect the water level downstream of the garbage cleaning machine 30. The second power supply 42 is a weak power supply. The second power supply 42 is used to continuously supply power to the first water level sensor 211 and the second water level sensor 212, so that the first water level sensor 211 can continuously detect the upstream water level of the garbage cleaning machine 30, and send the upstream water level signal to the first control module 22, and the second water level sensor 212 can continuously detect the downstream water level of the garbage cleaning machine 30, and send the downstream water level signal to the first control module 22. The second power supply 42 can also continuously supply power to the first control module 22 as needed. The first control module 22 processes the received upstream water level condition signal and the downstream water level condition signal, for example, calculates the difference between the upstream water level value and the downstream water level value to obtain the actual water level difference, and compares the obtained actual water level difference with the set water level difference preset by the first control module 22. The set water level difference can be determined according to experimental data. Generally, the larger the water inlet, the smaller the set water level difference; when the actual water level difference is greater than the set water level difference, the first control module 22 sends a first control signal to control the cleaning machine 30 to be connected to the first power supply 41; when the actual water level difference is less than the set water level difference, the first control module 22 sends a second control signal to control the cleaning machine 30 to be disconnected from the first power supply 41; the first power supply 41 is a strong power supply.
[0031] Therefore, the garbage cleaning machine 30 does not need to be in operation continuously. When the difference (actual water level difference) between the upstream and downstream water levels of the garbage cleaning machine 30 detected by the first water level sensor 211 and the downstream water level of the garbage cleaning machine 30 detected by the second water level sensor 212 is greater than the set water level difference, the first control module 22 determines that the dirt on the garbage cleaning machine 30 needs to be cleaned. At this time, the garbage cleaning machine 30 is controlled to be connected to the strong power supply by the first control signal sent, so that the garbage cleaning machine 30 does not need to be connected to the strong power supply all the time. In addition, since the first water level sensor 211, the second water level sensor 212 and the first control module 22 are powered by a weak power supply, the garbage cleaning machine 30 can be automatically started and stopped without continuous power supply from a strong power supply and without anyone on duty at the garbage cleaning machine 30, which saves energy consumption and complies with safety operating procedures. Moreover, compared with other devices for detecting water levels, the water level sensor used to detect water levels has high detection accuracy, can provide a variety of signal output options, is suitable for different liquids such as clean water, sewage, corrosive liquids, etc., has strong applicability, is easy to install and maintain, has good stability, high protection level, strong anti-interference ability, high reliability, long service life, low cost and other beneficial effects. At the same time, by detecting the water level conditions upstream and downstream of the cleaning machine 30 to determine the situation of the dirt on the cleaning machine 30, it can monitor the situation of the dirt on the cleaning machine 30 in real time, quickly determine whether the cleaning machine 30 is blocked by dirt, and improve the cleaning efficiency; it can also improve the accuracy of detection; it can also facilitate the integrated setting of the first water level sensor 211 and the second water level sensor 212 in the water treatment facility; in addition, since water level monitoring is not limited by the type and size of dirt, the first water level sensor 211 and the second water level sensor 212 can be applied to more types of environments and conditions, have stronger environmental adaptability and applicability, and are easier to expand to more monitoring points.
[0032] As one embodiment of the first control module 22, the first control module 22 may be an MCU or a single-chip microcomputer commonly used in the prior art, and the present invention does not limit its specific model as long as it can realize the setting of the water level difference.
[0033] As some specific embodiments of the water level sensor, it can be a capacitive water level sensor, a photoelectric water level sensor, an ultrasonic water level sensor, a static pressure water level sensor and other water level sensors commonly used in the prior art. The present invention does not limit the specific type and model of the water level sensor. In some preferred embodiments, the first water level sensor 211 is arranged upstream of the grid body of the garbage cleaning machine 30; the second water level sensor 212 is arranged downstream of the grid body of the garbage cleaning machine 30. Thus, the first control module 22 can obtain the difference between the upstream and downstream water levels according to the water level conditions detected by the water level sensors upstream and downstream of the grid body, and then judge whether the dirt on the grid body has reached the level that needs to be cleaned, so as to improve the detection accuracy of the water level sensor. In some preferred embodiments, the first water level sensor 211 and the second water level sensor 212 are arranged in the measuring hole of the gate pier. This can prevent the water level sensor from being directly exposed to water flow or the external environment, reducing the risk of damage to the water level sensor. At the same time, it can ensure that the water level sensor can be stably installed to prevent the water level sensor from moving or tilting due to water flow fluctuations. In addition, it can also reduce the interference of water surface fluctuations, floating objects, aquatic plants, etc. on the water level sensor readings, reduce the maintenance frequency of the water level sensor, improve the detection accuracy of the water level sensor and the continuity of data detection, and facilitate regular calibration and maintenance of the water level sensor.
[0034] In some preferred embodiments, the first water level sensor 211 and the second water level sensor 212 are arranged in pairs. Thus, the first control module 22 can obtain the difference between the upstream and downstream water levels through the upstream water level detected by the first water level sensor 211 and the downstream water level detected by the second water level sensor 212. Further preferably, at least two pairs of the first water level sensor 211 and the second water level sensor 212 arranged in pairs are arranged along the vertical direction of the water flow to further improve the accuracy of the water level sensor detection.
[0035] In some embodiments, Figure 1 As shown, the first water level sensor 211 and the second water level sensor 212 arranged in pairs constitute the detection module 21 of an embodiment of the present utility model. The upstream water level condition signal of the garbage cleaning machine 30 detected by the first water level sensor 211 and the downstream water level condition signal of the garbage cleaning machine 30 detected by the second water level sensor 212 are the first detection signals sent by the detection module 21 to the first control module 22.
[0036] In some embodiments, Figure 1As shown, the first water level sensor 211 and the second water level sensor 212 arranged in pairs, and the first control module 22 together constitute the dirt detection control module 20 of an embodiment of the present utility model. As a result, the garbage cleaning machine 30 does not need to be in a continuous operation state, and only needs to send a first control signal to control the garbage cleaning machine 30 to start running when the garbage detection control module 20 detects that the dirt on the garbage cleaning machine 30 needs to be cleaned, so that the garbage cleaning machine 30 does not need to be connected to the strong power supply all the time; and because the garbage detection control module 20 is powered by a weak power supply, it can realize the automatic start and stop of the garbage cleaning machine 30 without continuous power supply from a strong power supply and without anyone on duty at the garbage cleaning machine 30.
[0037] In other embodiments, the detection module 21 and the first control module 22 together constitute a dirt detection control module 20 of an implementation manner of the present utility model.
[0038] In some embodiments, the weak power supply is a power supply with a voltage lower than 24V. To ensure the safety of the operation of the dirt detection control module 20; moreover, even if the dirt detection control module 20 is powered continuously, it will not generate high energy consumption; at the same time, it can reduce the risk of damage to sensitive electronic equipment, reduce interference with signal transmission and electromagnetic, and generate less heat during operation, which helps to reduce heat loss; in addition, since the power cable of the weak power supply is generally thinner, it is convenient for the wiring and installation of the power cable, which helps to reduce the occupation of space. In some specific embodiments, the weak power supply is a solar cell or a battery. As long as the solar cell or battery can provide a stable low-voltage power supply for the dirt detection control module 20, it can be used as the weak power supply of the utility model. The utility model does not limit the specific form and model of the weak power supply. Selecting a solar cell as a weak power supply can save energy consumption; selecting a solar cell or a battery as a weak power supply can also achieve stable power supply to the dirt detection control module 20.
[0039] In some preferred embodiments, Figures 1 to 4 As shown, the dirt detection control module also includes a first time relay 61, which is preset with a first delay time. The first delay time can be determined through experiments. For example, the first delay time is set within 20S, for example, the first delay time is 20S, 15S, 10S, 5S, etc. The first time relay 61 is set so that when the dirt detection control module 20 sends a first control signal, the first time relay 61 disconnects the dirt cleaning machine 30 from the first power supply 41 for the first delay time, and then connects the dirt cleaning machine 30 to the first power supply 41. Therefore, when the actual water level difference between the upstream and downstream is greater than the set water level difference, the dirt cleaning machine 30 can be connected to the first power supply 41 after waiting for the first delay time, so as to avoid the dirt cleaning machine 30 from being started by mistake due to the water level difference caused by the waves.
[0040] In order to further clarify the control system of the garbage cleaning machine 30 of the present invention, a partial circuit diagram of an implementation of the control system of the garbage cleaning machine 30 is provided, as shown in FIG. Figure 2 As shown, the first water level sensor 211 is SQ1, the second water level sensor 212 is SQ2, the first control module 22 is the IM1 intelligent processing module (first control module), and KA1 is the main control relay. The first water level sensor 211 is SQ1, and the second water level sensor 212 is SQ2, which are respectively installed in front and behind the garbage cleaning machine 30, and are used to measure the water level data of the upstream and downstream of the garbage cleaning machine 30. The water level data is collected, converted, and the actual water level difference is calculated by the IM1 intelligent processing module. When the actual water level difference exceeds the set water level difference, the IM1 intelligent processing module controls the KA1 main control relay to be energized, and the normally open contact of the KA1 main control relay is closed. The KA1 main control relay is used to control the main circuit switch of the garbage cleaning machine to be closed, so as to connect the main circuit of the garbage cleaning machine to the first power supply.
[0041] In order to further clearly illustrate the control system of the garbage cleaning machine 30 of the present invention, another partial circuit diagram of an implementation of the control system of the garbage cleaning machine taking a rotary garbage cleaning machine as an example is also provided. Figure 3As shown, QF1 is the main circuit switch of the garbage cleaning machine, KT1 is the delayed connection time relay (first time relay 61), and KM0 is the motor control contactor of the rotary motor. Under normal circumstances, the main circuit switch QF1 of the garbage cleaning machine is in an open state, and the garbage cleaning machine is in a state of being disconnected from the first power supply. When the KA1 main control relay is energized, the KA1 main control relay is closed; then the main circuit switch QF1 of the garbage cleaning machine is energized, the main circuit switch QF1 of the garbage cleaning machine is closed, and the main circuit is energized; at the same time, the delayed connection time relay KT1 is energized and starts timing. When the timing is completed, the normally open contact of the delayed connection time relay KT1 is closed, the motor control contactor KM0 of the rotary motor is energized, and the contact of the motor control contactor KM0 of the rotary motor is closed, and the rotary motor of the garbage cleaning machine is energized and starts to operate, and the garbage cleaning work begins. When the actual water level difference is less than the set water level difference, the IM1 intelligent processing module controls the KA1 main control relay to lose power, and the normally open contact of the KA1 main control relay opens; then the delayed on-time relay KT1 loses power, the normally open contact of the delayed on-time relay KT1 opens, the motor control contactor KM0 of the rotary motor loses power, and the rotary motor of the garbage cleaning machine stops working. In some specific embodiments, the first control module 22 controls the main circuit switch QF1 of the garbage cleaning machine to close or open by controlling the switch opening and closing control device, specifically, the first control module 22 controls the switch opening and closing control device to control the main circuit switch QF1 of the garbage cleaning machine to close or open; the main circuit switch QF1 of the garbage cleaning machine is the power switch; the switch opening and closing control device and the power switch can be placed in the first box. In some specific embodiments, the rotary motor can be a rake tooth rotary motor. In some specific embodiments, at least one of the main circuit switches KA1, QF1, KM0 and KT1 of the garbage cleaning machine can be a coil type.
[0042] In some preferred embodiments, Figure 1 and Figure 5As shown, the waste detection control module 20 is also configured to control the waste conveying device 50 to be connected to the first power supply 41 when it sends a first control signal; the waste detection control module also includes a second time relay 62, which is preset with a second delay time, and the second delay time can be determined by experiments, for example, the second delay time is set within 40S, for example, the second delay time is 40S, 30S, 20S, etc.; the second time relay 62 is configured to, when the waste cleaning machine 30 is disconnected from the first power supply 41, the second time relay 62 keeps the waste conveying device 50 and the first power supply 41 connected for the second delay time, and then disconnects the waste conveying device 50 from the first power supply 41. Thus, the waste unloaded by the garbage cleaning machine 30 can be transported away in real time, so as to avoid the waste accumulating near the garbage cleaning machine 30 and affecting the normal operation of the garbage cleaning machine 30; when the garbage cleaning machine 30 stops running, the waste conveying device 50 will also transport the waste unloaded by the garbage cleaning machine 30 to a place far away from the garbage cleaning machine 30, so as to avoid the waste accumulating near the garbage cleaning machine 30. In order to further clearly explain the control system of the garbage cleaning machine 30 of the utility model, as shown in FIG. Figure 3 As shown, KMT1 is the disconnection delay time relay (second time relay 62), and KM1 is the motor control contactor of the waste conveying device 50. When the KA1 main control relay is energized, the KA1 main control relay is closed; then the main circuit switch QF1 of the waste cleaning machine is energized, and the main circuit switch QF1 of the waste cleaning machine is closed, so as to realize the latching of the main circuit switch QF1 of the waste cleaning machine and the disconnection delay time relay KMT1, and the main circuit is energized; at the same time, the delayed connection time relay KT1 is energized and starts timing, when the timing is completed, the normally open contact of the delayed connection time relay KT1 is closed, the motor control contactor KM0 of the rotary motor and the motor control contactor KM1 of the waste conveying device 50 are energized, the contact of the motor control contactor KM0 of the rotary motor is closed, the rotary motor of the waste cleaning machine is energized to run, and the waste cleaning work is started, the contact of the motor control contactor KM1 of the waste conveying device 50 is closed, and the transport motor of the waste conveying device 50 is energized to run, and the waste transport work is started. When the actual water level difference is less than the set water level difference, the IM1 intelligent processing module controls the KA1 main control relay to lose power, and the normally open contact of the KA1 main control relay opens; then the delayed on-time relay KT1 loses power, the normally open contact of the delayed on-time relay KT1 opens, and the motor control contactor KM0 of the rotary motor of the garbage cleaning machine stops working, and the garbage cleaning work stops; at the same time, the disconnection delay time relay KMT1 loses power, and the disconnection delay time relay KMT1 performs disconnection timing; when the timing is completed, the normally closed contact of the disconnection delay time relay KMT1 opens, the main circuit switch QF1 of the garbage cleaning machine and the motor control contactor KM1 of the garbage conveying device 50 are opened, the main circuit is powered off, and the transport motor of the garbage conveying device 50 stops running, and the garbage transport work stops. In some specific embodiments, at least one of KM1 and KMT1 can be a coil type.
