The water circulation system is a component of the coal preparation production system, which is used to recycle the wastewater generated during the washing process to improve water utilization, reduce production costs, and reduce pollution to the environment.

[0003] In the water circulation system, the pump room plays a key role. The pump room is composed of water pumps, power machines, motor equipment and other auxiliary equipment, providing power for the entire water circulation system so that water can circulate as needed.

[0004] However, during the production process, due to pipeline wear, mechanical seal wear, aging of rubber sealing parts, etc., pipeline and equipment leakage may occur, causing water accumulation in the pump room. However, the inspection interval is long, and there is a risk that the water accumulation problem cannot be discovered in time. Utility Model Content

[0005] The present application provides a pump room liquid level monitoring and early warning device to solve the problem that water accumulation in the pump room cannot be detected and drained in time in the water circulation system of the coal preparation production system.

[0006] The present application provides a pump room liquid level monitoring and early warning device, including a monitoring and early warning circuit and a liquid storage mechanism;

[0007] The monitoring and early warning circuit includes a first liquid level sensor, an alarm and a main controller;

[0008] The liquid storage mechanism is arranged inside the pump room and includes a groove-shaped liquid storage cavity;

[0009] The main controller is arranged outside the liquid storage mechanism and includes a first input interface and a first output interface;

[0010] The first liquid level sensor is connected to the first input interface and includes a first probe;

[0011] The first probe is arranged above the liquid storage cavity;

[0012] The alarm is connected to the first output interface and is arranged outside the liquid storage mechanism.

[0013] In the above device, the main controller is used for control. The first liquid level sensor is arranged above the liquid storage mechanism to monitor the liquid level height in the liquid storage mechanism, so that the device can start or stop the discharge process according to the liquid level height, and issue an alarm when a failure occurs in the discharge process or liquid overflows, reminding the operator to deal with it in time, thereby realizing automatic monitoring and alarm of the liquid level and solving the problem of water accumulation in the pump room in time.

[0014] In a possible implementation, the monitoring and early warning circuit further includes a second liquid level sensor;

[0015] The main controller also includes a second input interface;

[0016] The second liquid level sensor is connected to the second input interface.

[0017] In the above device, the second liquid level sensor is also used to monitor the liquid level height in the liquid storage mechanism, that is, different types of liquid level sensors can be used to monitor the liquid level height in the liquid storage mechanism, thereby increasing the scalability of the pump room liquid level monitoring and early warning device.

[0018] In a possible implementation, the second liquid level sensor includes a second probe;

[0019] The second probe is arranged inside the liquid storage cavity.

[0020] In the above device, the second probe of the second liquid level sensor is arranged at an appropriate position inside the liquid storage chamber. When the liquid level reaches or is lower than the height of the second probe, the second liquid level sensor inputs a liquid level signal to the main controller, so that the device starts or stops the discharge process according to the liquid level.

[0021] In a possible implementation, the pump room liquid level monitoring and early warning device further includes a liquid discharge mechanism;

[0022] The main controller also includes a second output interface;

[0023] The liquid discharge mechanism is connected to the second output interface.

[0024] In the above device, when the liquid level exceeds the specified height, the main controller receives the liquid level signal from the first liquid level sensor or the second liquid level sensor, and after processing, outputs a start discharge signal to the discharge mechanism, and the discharge mechanism starts to discharge; when the liquid level is lower than the specified height, the main controller receives the safety height liquid level signal from the first liquid level sensor or the second liquid level sensor, and after processing, outputs a stop discharge signal to the discharge mechanism, thereby achieving the purpose of starting automatic discharge when the liquid level is too high and stopping automatic discharge when the liquid level meets the standard.

[0025] In a possible implementation, the liquid discharge mechanism includes a liquid infusion pipeline and a liquid discharge pump;

[0026] The liquid discharge pump is arranged on the liquid infusion pipeline, and the liquid infusion pipeline is connected with the liquid storage cavity.

[0027] In the above device, the infusion pipeline is connected to the liquid storage chamber. After the liquid discharge starts, the liquid can be discharged from the liquid storage chamber through the infusion pipeline under the action of the liquid discharge pump, ensuring that the device has the function of discharging liquid.

[0028] In a possible implementation, the monitoring and early warning circuit further includes a third liquid level sensor;

[0029] The main controller also includes a third input interface;

[0030] The third liquid level sensor is connected to the third input interface.

[0031] In the above device, the third liquid level sensor is used to monitor the overflowed liquid. When liquid overflows from the liquid storage mechanism to the outside and contacts the third liquid level sensor, the third liquid level sensor will input the overflow signal to the main controller, and then the main controller will control the alarm to sound an alarm and output an alarm signal at the same time, so as to achieve the purpose of alarming when the liquid overflows.

[0032] In a possible implementation, the third liquid level sensor includes a third probe;

[0033] The third probe is arranged outside the liquid storage cavity.

[0034] In the above device, the third probe of the third liquid level sensor is arranged outside the liquid storage cavity of the liquid storage mechanism. When the liquid in the liquid storage mechanism has filled the liquid storage cavity and overflowed to the outside of the liquid storage cavity, the third probe outside the liquid storage cavity can detect the liquid overflow, thereby achieving the purpose of timely monitoring the liquid overflow.

[0035] In a possible implementation, the monitoring and early warning circuit further includes a time relay;

[0036] The main controller also includes a fourth input interface and a third output interface;

[0037] The time relay is connected to the fourth input interface and the third output interface.

[0038] In the above device, when the first liquid level sensor or the second liquid level sensor monitors that the liquid level has reached a specified height, the main controller outputs a start draining signal to the drain mechanism and outputs a start timing signal to the time relay. The time relay is used to record the draining time and compare the current draining time with the preset draining time. If the current draining time exceeds the preset draining time, the time relay does not receive a stop draining signal, that is, the first liquid level sensor or the second liquid level sensor does not detect that the liquid level has dropped to a safe height, which means that the drain mechanism has not been able to drain the liquid smoothly within the preset time. At this time, the time relay will input a fault signal to the main controller. After receiving the fault signal, the main controller will output an alarm signal, the alarm in the pump room will start the alarm, and the receiving terminal outside the pump room will display the alarm information to ensure that the fault of the draining device can be reported in time to avoid water accumulation caused by the fault of the draining device.

[0039] In a possible implementation, the pump room liquid level monitoring and early warning device further includes an electronic connection line;

[0040] The electronic connecting line is arranged in the monitoring and early warning circuit, and is used for connecting the first liquid level sensor, the alarm, the second liquid level sensor, the liquid discharge mechanism, the third liquid level sensor, the time relay and the main controller.

[0041] In the above device, components such as the first liquid level sensor, the alarm, the second liquid level sensor, the drainage mechanism, the third liquid level sensor, the time relay and the main controller are connected to form a monitoring and early warning circuit through electronic connecting lines, so that the various components cooperate with each other to complete the purpose of liquid level monitoring and early warning in the pump room.

[0042] In a possible implementation, the pump room liquid level monitoring and early warning device further includes an information receiving terminal;

[0043] The information receiving terminal is arranged outside the pump room;

[0044] The information receiving terminal is connected to the main controller for communication and is used for receiving the alarm signal output by the main controller.

[0045] In the above device, when the discharge mechanism fails or the third liquid level sensor detects that liquid is overflowing from the liquid storage mechanism, the main controller will output an alarm signal. The information receiving terminal is connected to the main controller for communication and receives the alarm signal output by the main controller, thereby reminding the operating personnel that there is a water storage problem in the pump room.

[0046] It can be seen from the above technical scheme that the present application provides a pump room liquid level monitoring and early warning device, including a monitoring and early warning circuit and a liquid storage mechanism; wherein the monitoring and early warning circuit includes a first liquid level sensor, an alarm and a main controller; the liquid storage mechanism is arranged inside the pump room, including a groove-shaped liquid storage cavity; the main controller is arranged outside the liquid storage mechanism, including a first input interface and a first output interface; the first liquid level sensor is connected to the first input interface, including a first probe; the first probe is arranged above the liquid storage cavity; the alarm is connected to the first output interface, and is arranged outside the liquid storage mechanism. In the above device, the main controller is used for control, and the first liquid level sensor is arranged above the liquid storage mechanism to monitor the liquid level height in the liquid storage mechanism, so that the device starts or stops the process of draining liquid according to the liquid level height, and when a fault occurs in the drainage process or liquid overflows, an alarm is issued to remind the operator to deal with it in time, so as to realize automatic monitoring and alarm of the liquid level, and solve the problem of water storage in the pump room in time.

[0052] The following embodiments are described in detail, and examples thereof are shown in the accompanying drawings. When the following description refers to the drawings, unless otherwise indicated, the same numbers in different drawings represent the same or similar elements. The implementations described in the following embodiments do not represent all implementations consistent with the present application. They are only examples of systems and methods consistent with some aspects of the present application as detailed in the claims.

[0053] It should be noted that the brief description of terms in this application is only for the convenience of understanding the embodiments described below, and is not intended to limit the embodiments of this application. Unless otherwise specified, these terms should be understood according to their common and usual meanings.

[0054] The terms "first", "second", "third", etc. in the specification and claims of this application and the above drawings are used to distinguish similar or similar objects or entities, and do not necessarily mean to limit a specific order or sequence, unless otherwise noted. It should be understood that the terms used in this way can be interchangeable under appropriate circumstances.

[0055] The coal preparation production system is used to process raw coal, remove impurities and improve coal quality. The water circulation system is a component of the coal preparation production system, which is used to recycle the wastewater generated during the washing process to improve water utilization, reduce production costs, and reduce pollution to the environment.

[0056] In the water circulation system, the pump room plays a key role. The pump room includes dry room type pump room, wet room type pump room, split foundation type pump room and block foundation type pump room. Among them, the dry type pump room has good waterproof effect. Its walls, bottom plate and unit foundation are poured with reinforced concrete to form an impermeable whole, forming a dry basement. It is composed of water pumps, power machines, motor equipment and other auxiliary equipment to provide power for the entire water circulation system, so that water can circulate as needed.

[0057] Since the dry room pump room needs to be kept dry, water accumulation in the dry room pump room needs to be avoided during production operations. However, due to pipeline wear, mechanical seal wear, aging of rubber sealing components, etc., pipeline and equipment leakage may occur, causing water accumulation in the pump room. In addition, the inspection interval is long, and there is a risk that the water accumulation problem cannot be discovered in time.

[0058] In order to solve the problem that the water in the pump room cannot be found and drained in time in the water circulation system of the coal preparation production system, the present application provides a pump room liquid level monitoring and early warning device. Figure 1 The pump room liquid level monitoring and early warning device provided in some embodiments of the present application includes a monitoring and early warning circuit and a liquid storage mechanism 5; wherein the monitoring and early warning circuit includes a first liquid level sensor 3, an alarm 1 and a main controller 7; the liquid storage mechanism 5 is arranged inside the pump room, including a groove-shaped liquid storage cavity; the main controller 7 is arranged outside the liquid storage mechanism 5, including a first input interface and a first output interface; the first liquid level sensor 3 is connected to the first input interface, including a first probe; the first probe is arranged above the liquid storage cavity; the alarm 1 is connected to the first output interface, and is arranged outside the liquid storage mechanism 5.

[0059] For example, see Figure 1The first liquid level sensor 3 is a non-contact liquid level sensor, such as an ultrasonic liquid level meter. The probe of the ultrasonic liquid level meter is arranged above the liquid storage cavity, and can sense the current liquid level in the liquid storage mechanism 5 by emitting and receiving ultrasonic waves. When the liquid level in the liquid storage mechanism 5 reaches a specified height, the main controller 7 receives the specified height liquid level signal from the ultrasonic liquid level meter and outputs a liquid discharge start signal, so that the pump room liquid level monitoring and early warning device starts to discharge liquid.

[0060] When the liquid level in the liquid storage mechanism 5 drops to a safe height, there is no need to discharge the liquid any more. After receiving the safe height liquid level signal from the ultrasonic liquid level meter, the main controller 7 outputs a stop discharge signal to stop the pump room liquid level monitoring and early warning device from discharging the liquid.

[0061] It can be understood that the first liquid level sensor 3 is arranged above the liquid storage chamber, and can sense the liquid level height without contacting the liquid in the liquid storage chamber, and is a non-contact liquid level sensor. There are many types of non-contact liquid level sensors, in addition to ultrasonic liquid level meters, other types of non-contact liquid level sensors can also be used, such as infrared tubes, etc., which are not specifically limited in the embodiments of the present application.

[0062] When a failure occurs during the liquid discharge process or the liquid has overflowed from the liquid storage mechanism 5, the main controller 7 sends an alarm signal to the alarm in the pump room and the receiving terminal outside the pump room, controls the alarm 1 in the pump room to start the alarm, and transmits the alarm information to the operator outside the pump room. Among them, the alarm 1 can be an audible and visual alarm, which uses sound and light to alarm, which can attract the attention of the operator more intuitively and quickly, thereby improving the operator's alertness and reaction speed, so that the operator can find the water storage problem in the pump room as soon as possible.

[0063] In other embodiments, see Figure 2 The monitoring and early warning circuit also includes a second liquid level sensor 9; the main controller 7 also includes a second input interface; wherein the second liquid level sensor 9 is connected to the second input interface.

[0064] It can be understood that the second liquid level sensor 9 is also used to monitor the liquid level height in the liquid storage mechanism, but the way of monitoring the liquid level height is different from that of the first liquid level sensor 3 .

[0065] In some embodiments, the second liquid level sensor 9 includes a second probe; wherein the second probe is disposed inside the liquid storage cavity.

[0066] For example, see Figure 2The second liquid level sensor 9 is a contact type liquid level sensor, such as a water immersion sensor, and the probe of the water immersion sensor is arranged inside the liquid storage cavity. The working principle of the water immersion sensor is that when the liquid contacts the electrode on the water immersion sensor to form a conductive path, the current starts to flow, and the output state of the water immersion sensor changes, thereby sensing whether the current liquid level height in the liquid storage mechanism 5 has reached the specified height. When the liquid level height in the liquid storage mechanism 5 reaches the specified height, the main controller 7 receives the specified height liquid level signal from the water immersion sensor and outputs a start draining signal to start draining the pump room liquid level monitoring and early warning device.

[0067] When the liquid level in the liquid storage mechanism 5 drops to a safe height, there is no need to discharge the liquid any more. After receiving the safe height liquid level signal from the water immersion sensor, the main controller 7 outputs a stop discharge signal to stop the pump room liquid level monitoring and early warning device from discharging the liquid.

[0068] It can be understood that the second liquid level sensor 3 is arranged inside the liquid storage chamber, and senses the liquid level by contacting the liquid in the liquid storage chamber, and is a contact liquid level sensor. There are many types of contact liquid level sensors, and in addition to water immersion sensors, other types of contact liquid level sensors can also be used, such as pressure sensors, etc., which are not specifically limited in the embodiments of the present application.

[0069] In some embodiments, the pump room liquid level monitoring and early warning device further includes a liquid discharge mechanism 2; the main controller 7 further includes a second output interface; wherein the liquid discharge mechanism 2 is connected to the second output interface.

[0070] For example, see Figure 1 The discharge mechanism 2 is connected to the second output interface of the main controller 7. When the first liquid level sensor 3 detects that the liquid level has reached the specified drainage height, the main controller 7 receives the specified height liquid level signal input by the first liquid level sensor 3, and then outputs a start discharge signal to the discharge mechanism 2 to control the discharge mechanism 2 to discharge liquid outward; when the liquid level drops to a safe height, the main controller 7 receives the safe height liquid level signal input by the first liquid level sensor 3, and then outputs a stop discharge signal to the discharge mechanism 2 to control the discharge mechanism 2 to stop discharging liquid.

[0071] For example, see Figure 2 The discharge mechanism 2 is connected to the second output interface of the main controller 7. When the second liquid level sensor 9 contacts the liquid, that is, the liquid level reaches the specified drainage height, the main controller 7 receives the specified height liquid level signal input by the second liquid level sensor 9, and then outputs a start discharge signal to the discharge mechanism 2 to control the discharge mechanism 2 to discharge the liquid outward; when the liquid level drops to a safe height, the main controller 7 receives the safe height liquid level signal input by the second liquid level sensor 9, and then outputs a stop discharge signal to the discharge mechanism 2 to control the discharge mechanism 2 to stop discharging the liquid.

[0072] In some embodiments, the drainage mechanism 2 includes an infusion pipeline and a drainage pump; wherein the drainage pump is disposed on the infusion pipeline, and the infusion pipeline is connected to the liquid storage cavity.

[0073] It can be understood that the infusion pipeline is connected to the liquid storage chamber to form a drainage mechanism 2. After the drainage starts, the liquid can be discharged from the liquid storage chamber through the infusion pipeline under the action of the drainage pump, and discharged from the liquid storage mechanism 5, so that the liquid level of the liquid storage mechanism 5 reaches a safe height.

[0074] In some embodiments, the monitoring and early warning circuit further includes a third liquid level sensor 4; the main controller 7 further includes a third input interface; wherein the third liquid level sensor 4 is connected to the third input interface.

[0075] It can be understood that the third liquid level sensor 4 is used to monitor overflowed liquid. When liquid overflows from the liquid storage mechanism 5 to the outside and contacts the third liquid level sensor 4, the third liquid level sensor 4 will input the overflow signal to the main controller 7, and then the main controller 7 will control the alarm 1 to sound an alarm and output an alarm signal at the same time, thereby achieving the purpose of alarming when liquid overflows.

[0076] In some embodiments, the third liquid level sensor 4 includes a third probe; wherein the third probe is disposed outside the liquid storage cavity.

[0077] For example, see Figure 1 The third liquid level sensor 4 is a contact liquid level sensor, such as a water immersion sensor, and the probe of the water immersion sensor is arranged on a platform outside the liquid storage mechanism 5. When liquid overflows from the liquid storage mechanism 5 onto the external platform, the electrode on the water immersion sensor contacts the overflowed liquid to form a conductive path, and the current begins to flow. The output state of the water immersion sensor changes, and an overflow signal is generated. After receiving the overflow signal from the water immersion sensor, the main controller 7 outputs an alarm signal. After receiving the alarm signal, the alarm 1 in the pump room starts to alarm. After receiving the alarm signal, the receiving terminal outside the pump room prompts the operator that there is a water problem in the pump room.

[0078] It can be understood that the third liquid level sensor 4 is arranged on the platform outside the water storage mechanism 5, and determines the overflow of the liquid by contacting with the overflowing liquid, and is a contact liquid level sensor. There are many types of contact liquid level sensors, and in addition to water immersion sensors, other types of contact liquid level sensors can also be used, such as pressure sensors, etc., which are not specifically limited in the embodiments of the present application.

[0079] It is understandable that the third liquid level sensor 4 is used to monitor the liquid overflowing from the liquid storage mechanism 5 and can be arranged at Figure 1 On the left side platform outside the liquid storage mechanism 5, it can also be arranged Figure 1On the right side platform outside the middle liquid storage mechanism 5, as long as it can be ensured that the liquid can contact the third liquid level sensor 4 as soon as possible after overflowing, no specific limitation is made in the embodiment of the present application.

[0080] In some embodiments, the monitoring and early warning circuit further includes a time relay 6; the main controller 7 further includes a fourth input interface and a third output interface; wherein the time relay 6 is connected to the fourth input interface and the third output interface.

[0081] For example, see Figure 1 When the first liquid level sensor 3 monitors that the liquid level has reached a specified height, the first liquid level sensor 3 sends a specified height liquid level signal to the main controller 7. The main controller 7 outputs a start draining signal to the drain mechanism 2 and a start timing signal to the time relay 6. The time relay 6 starts recording the draining time and compares the current draining time with the preset draining time. If the current draining time exceeds the preset draining time, the time relay 6 does not receive a stop draining signal, that is, the first liquid level sensor 3 does not detect that the liquid level has dropped to a safe height, which means that the drain mechanism 2 has failed to drain the liquid smoothly within the preset time. At this time, the time relay 6 will input a fault signal to the main controller 7. After receiving the fault signal, the main controller 7 outputs an alarm signal, the alarm 1 in the pump room starts the alarm, and the receiving terminal outside the pump room displays the alarm information.

[0082] For example, see Figure 2 When the second liquid level sensor 9 monitors that the liquid level reaches the specified height, the second liquid level sensor 9 sends a specified height liquid level signal to the main controller 7. The main controller 7 outputs a start draining signal to the drain mechanism 2 and a start timing signal to the time relay 6. The time relay 6 starts recording the draining time and compares the current draining time with the preset draining time. If the current draining time exceeds the preset draining time, the time relay 6 does not receive a stop draining signal, that is, the second liquid level sensor 9 does not detect that the liquid level has dropped to a safe height, which means that the drain mechanism 2 has failed to drain the liquid smoothly within the specified time. At this time, the time relay 6 will input a fault signal to the main controller 7. After receiving the fault signal, the main controller 7 outputs an alarm signal, the alarm 1 in the pump room starts the alarm, and the receiving terminal outside the pump room displays the alarm information.

[0083] It is understandable that the time relay 6 is used to record the drainage time and judge whether the drainage process is normal according to the preset time and the current drainage time. If it is not normal, a fault signal will be issued. There are other components that can realize this function, such as timers, etc., which are not specifically limited in the embodiments of the present application.

[0084] In some embodiments, the above-mentioned pump room liquid level monitoring and early warning device also includes an electronic connecting line; wherein, the electronic connecting line is arranged in the monitoring and early warning circuit, and is used to connect the first liquid level sensor 3, the alarm 1, the second liquid level sensor 9, the drainage mechanism 2, the third liquid level sensor 4, the time relay 6 and the main controller 7.

[0085] For example, see Figure 1 The electronic connecting line is used to connect the first liquid level sensor 3, the alarm 1, the discharge mechanism 2, the third liquid level sensor 4, the time relay 6 and the main controller 7.

[0086] For example, see Figure 2 The electronic connecting line is used to connect the second liquid level sensor 9, the alarm 1, the discharge mechanism 2, the third liquid level sensor 4, the time relay 6 and the main controller 7.

[0087] In some embodiments, the above-mentioned pump room liquid level monitoring and early warning device also includes an information receiving terminal 8; wherein the information receiving terminal 8 is arranged outside the pump room; the information receiving terminal 8 is communicatively connected with the main controller 7, and is used to receive the alarm signal output by the main controller 7.

[0088] For example, see Figure 1 The information receiving terminal 8 is an electronic computer, which is connected to the main controller 7 by communication. After the discharge mechanism 2 starts to discharge, the time relay 6 starts timing. When the discharge time exceeds the preset time in the time relay 6, the time relay 6 inputs a fault signal to the main controller 7. After processing, the main controller 7 outputs an alarm signal to the information receiving terminal 8 by communication.

[0089] For example, see Figure 1 The information receiving terminal 8 is an electronic computer, which is connected to the main controller 7 by communication. When the liquid in the liquid storage mechanism 5 overflows onto the external platform and contacts the third liquid level sensor 4, the third liquid level sensor 4 inputs an overflow signal to the main controller 7. After receiving the overflow signal, the main controller 7 outputs an alarm signal to the information receiving terminal 8 by communication.

[0090] It can be understood that the information receiving terminal 8 is a device for receiving the alarm signal output by the main controller 7, and can be a laptop computer, a desktop computer or a single-chip microcomputer, etc., and is not specifically limited in the embodiments of the present application.

[0091] It can be understood that the communication method between the main controller 7 and the information receiving terminal 8 can be wired communication, such as fiber optic communication, or wireless communication, such as RS-485 communication, etc., as long as the alarm signal in the main controller 7 can be transmitted to the information receiving terminal 8, and no specific limitation is made in the embodiments of the present application.

[0092] It can be seen from the above technical scheme that the present application provides a pump room liquid level monitoring and early warning device, including a monitoring and early warning circuit and a liquid storage mechanism; wherein the monitoring and early warning circuit includes a first liquid level sensor, an alarm and a main controller; the liquid storage mechanism is arranged inside the pump room, including a groove-shaped liquid storage cavity; the main controller is arranged outside the liquid storage mechanism, including a first input interface and a first output interface; the first liquid level sensor is connected to the first input interface, including a first probe; the first probe is arranged above the liquid storage cavity; the alarm is connected to the first output interface, and is arranged outside the liquid storage mechanism. In the above device, the main controller is used for control, and the first liquid level sensor is arranged above the liquid storage mechanism to monitor the liquid level height in the liquid storage mechanism, so that the device starts or stops the process of draining liquid according to the liquid level height, and when a fault occurs in the drainage process or liquid overflows, an alarm is issued to remind the operator to deal with it in time, so as to realize automatic monitoring and alarm of the liquid level, and solve the problem of water storage in the pump room in time.
