Also, features described with respect to some examples can be combined in other examples.
[0021] The following will be described in conjunction with Figures 1-2 The embodiments of the present application are described.
[0022] As Figure 1 shown, a fire pool water tank liquid level monitoring system, the water inlet pipe of the fire pool water tank a is provided with a water inlet valve b, the monitoring system includes a liquid level acquisition module 1, a control module 2 and a bypass module 3; the liquid level acquisition module 1 is connected with the fire pool water tank a and the control module 2, for collecting the liquid level information of the fire pool water tank a, and transmitting the liquid level information to the control module 2; the control module 2 includes a water inlet and outlet control unit 2-2 and an alarm unit 2-1, the water inlet and outlet control unit 2-2 is used for generating switching instruction of controlling the opening and closing state of the water inlet valve b according to the liquid level information, the alarm unit 2-1 is used for generating alarm signal according to the liquid level information; the bypass module 3 is electrically connected with the control module 2, for interrupting the operation of the alarm unit 2-1; the control module 2 further includes a power module, and the power module is used for power supply for the water inlet valve.
[0023] Specifically, the water inlet valve b is an electromagnetic valve. When the water inlet valve b is opened, the water level in the fire pool water tank a starts to rise. The liquid level acquisition module 1 monitors the water level in the fire pool water tank a, and confirms whether the water level in the fire pool water tank a is in a rising state or a falling state by comparing the water level at different times. The liquid level acquisition module 1 converts the monitored liquid level information into an electrical signal and transmits it to the control module 2. When the water level in the fire pool water tank a exceeds the preset overflow water level of the fire pool water tank a, the control module 2 closes the water inlet valve b to stop water from being supplied to the fire pool water tank a. When the water level in the fire pool water tank a is lower than the preset highest water level, it may be a fire or a fault. When the fire or fault is over, the bypass module 3 interrupts the alarm unit 2-1 to avoid false alarm of the fire pool water tank a during water storage.
[0024] As an option of the embodiment of the present application, the liquid level acquisition module 1 includes a liquid level transmitter 1-1 and a liquid level display 1-2 connected with the liquid level transmitter 1-1. The liquid level transmitter 1-1 is arranged in the fire pool water tank a to acquire the liquid level information of the fire pool water tank a. The liquid level display 1-2 is electrically connected with the control module 2 to transmit the liquid level information to the control module 2.
[0025] Further, the liquid level acquisition module 1 can also use a float ball type liquid level device to replace the liquid level transmitter 1-1 to acquire the liquid level information in the fire pool water tank a.
[0026] As an option of the embodiment of the present application, the control module 2 is provided with liquid level matching information, which includes overflow liquid level, highest liquid level, lowest liquid level and no water liquid level. The overflow liquid level, the highest liquid level, the lowest liquid level and the no water liquid level can be set as standard amount or fluctuation amount. The management personnel selects a liquid level between the overflow liquid level and the highest liquid level as the preset standard liquid level.
[0027] As an option of the embodiment of the present application, the alarm unit 2-1 is used to generate an alarm signal when the liquid level information is at the no water liquid level, the lowest liquid level and the highest liquid level. When a fire or a fault occurs, the water level in the fire pool water tank a starts to decrease. Therefore, the alarm unit 2-1 performs segmented alarm until the fire or maintenance personnel arrives.
[0028] As an option of the embodiment of the present application, the water inlet and outlet control unit 2-2 is used to generate a water inlet valve closing instruction to the water inlet valve b when the liquid level information is higher than the overflow liquid level. When the water level in the fire pool water tank a is supplemented, if the water level exceeds the overflow liquid level, the water in the fire pool water tank a will overflow, causing waste. Therefore, the water inlet valve b is controlled to be closed by the water inlet valve closing instruction to stop water storage.
[0029] Further, the water inlet and outlet control unit 2-2 is further configured to generate an open water inlet valve instruction to the water inlet valve b to switch the water inlet valve b to an open state to store water for the fire pool water tank a when the liquid level information is lower than the highest liquid level.
[0030] As an option of the embodiment of the present application, the bypass module 3 is configured to generate an alarm interrupt instruction to the alarm unit 2-1 when the liquid level of the fire pool water tank a is in the rising state. When the fire is over and the fire-fighting facilities in the building stop spraying water, the fire pool water tank a needs to be refilled. To avoid the alarm unit 2-1 from generating an alarm signal during the water storage process, the bypass module 3 generates an alarm interrupt instruction to interrupt the operation of the alarm unit 2-1.
[0031] As an option of the embodiment of the present application, the monitoring system further comprises a liquid level control box housing, wherein the liquid level acquisition module 1, the control module 2, and the bypass module 3 are arranged in the liquid level control box housing; the liquid level control box housing is arranged in a fire pump control room, and the protection level of the liquid level control box housing is not less than IP30.
[0032] Specifically, in the IP30 standard, the first digit represents the dustproof level, and the digit 3 indicates that the equipment has a dustproof level of 3, which means that it has a certain degree of protection against solid objects with a diameter greater than 2.5 mm; the second digit represents the waterproof level, and the digit 0 indicates that the equipment has a waterproof level of 0, i.e., it has no waterproof capability.
[0033] As an option of the embodiment of the present application, the monitoring system further comprises a liquid level control box housing, wherein the liquid level acquisition module 1, the control module 2, and the bypass module 3 are arranged in the liquid level control box housing; the liquid level control box housing is arranged in a fire pump control room, and the protection level of the liquid level control box housing is not less than IP30.
[0034] Specifically, in the IP55 standard, the first digit represents the dustproof level, and the digit 5 indicates that the equipment has a dustproof level of 5, which means that it can completely prevent foreign matter from entering, although it cannot completely prevent dust from entering, but the amount of dust that enters will not affect the normal operation of the equipment; the second digit represents the waterproof level, and the digit 5 indicates that the equipment has a waterproof level of 5, i.e., it can ensure that the equipment will not be waterlogged when sprayed with low-pressure water at any angle, thereby ensuring the normal operation of the equipment.
[0035] It can be understood that the liquid level control box shell arranged in the fire pump control room is in a relatively closed space, and is less affected by external environment such as temperature, humidity, dust and the like, so that the protection level requirement can be relatively low, and the protection level is set to IP30 and above, which can meet the requirement of indoor use and reduce the production cost. The liquid level control box shell arranged in the fire pump house is in a relatively complex working environment, so that the protection level requirement is higher, so as to avoid the interference of external environment on the equipment arranged in the liquid level control box shell and ensure the normal operation of the equipment.
[0036] The above description of disclosed embodiments enables those skilled in the art to carry out or use the present application. Various modifications to these embodiments will be apparent to those skilled in the art, and the general principles defined herein can be implemented in other embodiments without departing from the spirit or scope of the present application; therefore, the present application will not be limited to the embodiments shown herein, but will conform to the widest scope consistent with the principles and novel features disclosed herein.
