Description

Technical Field

[0001] The utility model relates to the technical field of water supply and drainage equipment, in particular to a troubleshooting system for secondary water supply equipment. Background Art

[0002] With the development of building technology, most of the current civilian residences have become high-rise. However, the problem of water supply pressure also follows. Since the pressure of municipal water supply is difficult to meet the needs of a large number of high-rise civilian residences, it is necessary to adopt the method of secondary water supply for pressurized water supply for each high-rise residence.

[0003] However, there are also many problems in the actual use of the secondary water supply system. Especially after large-scale use in high-rise residences, the water supply company needs to pay a considerable cost for the repair and maintenance of these secondary water supply systems. Especially after long-term use of the water pipes in the secondary water supply system, the phenomenon of pipeline aging is likely to occur, which is particularly likely to occur in areas with large temperature differences, frequent extreme weather and increasing building heights. When the pipeline ages to a certain extent or the pipeline freezes and cracks due to a sudden drop in temperature, the probability of the water supply pipeline bursting will increase. In current actual use, it is found that the probability of failure of many secondary water supply systems increases exponentially after 5-10 years of use.

[0004] In the current solutions, the main method is active monitoring, that is, a burst pipe monitoring device or monitoring system for the secondary water supply pipeline. Among them, it is necessary to add a monitoring module and a corresponding networking communication module to the secondary water supply system to achieve real-time monitoring of the water conveyance pipeline. Although real-time monitoring of the secondary water supply system in high-rise residences is achieved by adding a monitoring module and a corresponding networking communication module, the implementation cost is also increased. And if charged components such as the networking communication module also fail, troubleshooting cannot be effectively carried out. According to years of application practice experience, although water supply failure is also a problem related to people's livelihood, its urgency and danger are relatively lower than those of power supply and gas supply failures. Therefore, it is not absolutely necessary to adopt the active monitoring method for the secondary water supply system in high-rise residences.

[0005] Therefore, for the troubleshooting problem of the secondary water supply system in high-rise residences, it is necessary to design a solution with lower cost and easier to use, so as to reduce the cost of monitoring the failures of the secondary water supply systems in most civilian high-rise residences. Summary of the Utility Model

[0006] An embodiment of the utility model provides a troubleshooting system for secondary water supply equipment, which can reduce the cost of monitoring the failures of the secondary water supply systems in most civilian high-rise residences.

[0007] To achieve the above object, the embodiment of the utility model adopts the following technical solutions:

[0008] Secondary water supply equipment (1), explosion-proof pipe chip (2), water supply pipeline (3), emergency pipeline (4), water solenoid valve group and flowmeter group; both the water supply pipeline (3) and the emergency pipeline (4) are led out from the secondary water supply equipment (1) and connected to the flowmeter group through the water solenoid valve group; an explosion-proof pipe chip (2) is installed between the water solenoid valve group and the flowmeter group; the explosion-proof pipe chip (1) is used to trigger the water solenoid valve group to switch pipelines, where only one of the water supply pipeline (3) and the emergency pipeline (4) is in water supply at the same time; the flow rate of the water supply pipeline (3) is greater than that of the emergency pipeline (4).

[0009] In the prior art, the mainly adopted method is active monitoring, that is, for the burst pipe monitoring device or monitoring system of the secondary water supply pipeline, where it is necessary to add a monitoring module and a corresponding networking communication module to the secondary water supply system to achieve real-time monitoring of the water conveyance pipeline. Most of these existing solutions are actually technology transfers from the industrial field. Because in industrial production, factors such as efficiency and safety need to be strictly considered, there is a strong demand for real-time monitoring, and it is necessary to effectively monitor the water supply system or liquid supply system of factories and workshops. However, there are still problems of too high costs when applying these technologies in a large number of civil high-rise residential buildings. Although real-time monitoring of the secondary water supply system of high-rise residential buildings is achieved by adding a monitoring module and a corresponding networking communication module, the implementation cost is also increased. And if charged components such as the networking communication module also fail, it is still impossible to effectively troubleshoot (such as some current pipeline explosion-proof devices for secondary water supply equipment). Also, due to the increasing labor cost of maintenance personnel in recent years, the maintenance area that a single maintenance personnel needs to be responsible for is getting larger and larger. After problems occur in the secondary water supply systems of many high-rise residential buildings, even if the faults can be reported in time through the monitoring module and the corresponding networking communication module, the operation and maintenance personnel still cannot arrive at the scene in time for fault handling. And based on years of application practice experience, although water supply faults are also issues related to people's livelihood, their urgency and danger are relatively lower compared to power supply and gas supply faults. Therefore, it is not absolutely necessary to adopt the active monitoring method for the secondary water supply systems of high-rise residential buildings.

[0010] The troubleshooting system for secondary water supply equipment provided by the embodiments of the present utility model actually implements a passive troubleshooting solution, and the passive troubleshooting solution of this embodiment is mainly applied to the scenarios of high-rise residential buildings in China at present. Specifically, since two pipes with different flow rates are used for water supply, when the secondary water supply equipment is working properly, the ordinary water supply pipe is default used to supply water to the high-rise residential building. At this time, the water pressure at the user's entrance is normal. If the water supply pipe fails, such as aging or bursting, the explosion-proof pipe chip will trigger the water solenoid valve group to switch the pipe, close the water supply pipe and activate the emergency pipe. At this time, the water pressure at the user's entrance will significantly decrease. The purpose of this is as follows:

[0011] 1. To maintain the basic water supply for users without interruption, while in the existing technical solutions, the water supply pipe is often directly interrupted, resulting in water cut-off for users.

[0012] 2. If there are no residents in the high-rise residential building, according to the installation standard, the property or the municipal government needs to cut off the water, electricity and gas input of the building, so there is no problem with the troubleshooting of the secondary water supply equipment. If there are residents in the high-rise residential building, when the residents feel that the water pressure at the entrance significantly decreases, they usually report the repair by phone (the repair of the water supply company is usually on standby for 24 hours) or through the existing application program of the water supply company. Then the operation and maintenance personnel will naturally know the high-rise residential building where the failure occurs, thus achieving the effect of passive troubleshooting in the end. Because in actual applications, after the secondary water supply system of high-rise residential buildings has problems, even if the failure can be reported in time through the monitoring module and the corresponding network communication module, the operation and maintenance personnel still cannot arrive at the scene in time for troubleshooting. However, the residents in the building can often feel the obvious change in the input water pressure immediately when using water (such as a direct water cut-off or extremely low water pressure). Usually, in such cases of obvious water pressure change, the residents will report the repair to the water supply company immediately. Therefore, in actual operation, it often happens that an alarm message is sent out by active monitoring, and then immediately followed by a repair call from a resident, while the maintenance personnel often take some time to arrive. Thus, it can be seen that it is normal for residents to call the water supply company for repair due to the change in the water pressure at the entrance. This is a widespread and objective phenomenon, and this behavior has essentially achieved the effect of troubleshooting and reporting for the water supply company.

[0013] Therefore, the improvement direction of this embodiment is to ensure that users do not lose water during a fault while reducing costs, and at the same time, an obvious change in the water pressure entering the household is formed, thus forming the so-called passive fault elimination. This embodiment does not require additional monitoring modules (such as cameras, indicator lights, humidity sensors, etc.) and corresponding networking communication modules (such as SMS alarms) as in the prior art, thereby saving a large amount of component costs. Also, since it is necessary to add additional monitoring modules and corresponding networking communication modules, the main control chip in the explosion-proof pipe chip in the solution of this embodiment does not need to provide computing power support for additional functions such as monitoring and networking. It only needs to open / close the valves on the corresponding pipelines according to the output results of the flow meter. Therefore, a more cost-effective PLC single-chip microcomputer can be used, further saving costs. Brief Description of the Drawings

[0017] An embodiment of the present utility model provides a troubleshooting system for secondary water supply equipment, as Figure 1 shown, including: a secondary water supply equipment 1, an explosion-proof pipe chip 2, a water supply pipe 3, an emergency pipe 4, a water solenoid valve group and a flowmeter group; both the water supply pipe 3 and the emergency pipe 4 are led out from the secondary water supply equipment 1 and are connected to the flowmeter group through the water solenoid valve group; an explosion-proof pipe chip 2 is installed between the water solenoid valve group and the flowmeter group; the explosion-proof pipe chip 1 is used to trigger the water solenoid valve group to switch the pipeline, wherein only one of the water supply pipe 3 and the emergency pipe 4 is in water flow at the same moment; the flow rate of the water supply pipe 3 is greater than that of the emergency pipe 4.

[0018] Among them, the flow rate of the water supply pipe 3 is more than twice that of the emergency pipe 4. Preferably, the water supply pipe 3 uses a DN25 pipe, and the emergency pipe 4 uses a DN15 pipe. Among them, the flow rate Q of the water supply pipe 3 = 0.0491 * 40 = 1.064 liters per second, which is 7.07 cubic meters per hour; the flow rate Q of the emergency pipe 4 = 0.0177 * 40 = 0.708 liters per second, which is 2.55 cubic meters per hour.

[0019] In the explosion-proof pipe chip 1, it includes: an analog-to-digital conversion chip 1-2, a main control chip 1-3, and a power supply 1-6; the water solenoid valve group includes: a first water solenoid valve 1-4, a second water solenoid valve 1-5; both the first water solenoid valve 1-4 and the second water solenoid valve 1-5 are connected to the main control chip 1-3; the power supply 1-6 supplies power to the analog-to-digital conversion chip 1-2, the main control chip 1-3, the first water solenoid valve 1-4, and the second water solenoid valve 1-5. Among them, both the power supply 1-6 and the secondary water supply device 1 are connected to an external power supply, and the external power supply includes the main power supply of the residential building or the urban power grid.

[0020] Specifically, the analog-to-digital conversion chip 1-2 uses HXT9643; the main control chip 1-3 uses Delta PLCDVP-10PM. It should be noted that the secondary water supply device in this embodiment is mainly composed of components such as a regulating water tank, a water pump, and a control system. There is no special improvement to the secondary water supply device itself in this embodiment, so existing secondary water supply device products on the market can be directly used; the power supply (1-6) in this embodiment can also use common power supplies on the market for PLC power supply, and some power supplies are directly integrated on the PLC board. These are all very mature technologies and can be regarded as common knowledge. Therefore, the specific model of the power supply (1-6) and how it supplies power in this embodiment are not limited, and existing technologies can be directly adopted. The first water solenoid valve (1-4) and the second water solenoid valve (1-5) both belong to water solenoid valves. Water solenoid valves are very mature and common products, so the water solenoid valves in the solution of this embodiment can also directly purchase existing products. The turbine flowmeter is also a very mature and common product, so the turbine flowmeter in the solution of this embodiment can also directly purchase existing products.

[0021] The first water solenoid valve 1-4 is installed on the water supply pipeline 3, and the second water solenoid valve 1-5 is installed on the emergency pipeline 4. Among them, the main control chip 1-3 is used to trigger one of the first water solenoid valve 1-4 and the second water solenoid valve 1-5 to open and the other to remain closed; the flowmeter group includes turbine flowmeters installed on the water supply pipeline 3 and the emergency pipeline 4 respectively. In practical applications, the main control chip 1-3 switches the on / off of the solenoid valves, and the analog signal collected by the turbine flowmeter 1-1 is converted into a digital signal by the analog-to-digital conversion chip 1-2 and then transmitted to the main control chip 1-3. Then, the main control chip 1-3 controls the opening and closing of the first water solenoid valve 1-4 and the second water solenoid valve 1-5.

[0022] In the normal state, the secondary water supply device 1 draws water from the municipal pipeline to the water supply pipeline 3. The water flow rate of the water supply pipeline 3 is collected by the turbine flowmeter 1-1 installed on the water supply pipeline 3. The collected analog signal is converted into a digital signal by the analog-to-digital conversion chip 1-2 and then transmitted to the main control chip 1-3. The maximum and minimum values of the water flow rate are preset on the main control chip 1-3; if the water flow rate of the water supply pipeline 3 exceeds the maximum value or is lower than the minimum value, the main control chip 1-3 closes the first water solenoid valve 1-4 and opens the second water solenoid valve 1-5, so as to realize the switching of the water supply mode from the water supply pipeline 3 to the emergency pipeline 4, and the emergency pipeline 4 with a water flow rate significantly less than that of the normal water supply pipeline 3 continues to supply water to the residential building.

[0023] Each embodiment in this specification is described in a progressive manner. The same or similar parts among the embodiments can be referred to each other, and the key points of each embodiment are the differences from other embodiments. As described above, only the specific implementation manners of the present invention are provided, but the protection scope of the present invention is not limited thereto. Any changes or substitutions that can be easily thought of by those skilled in the art within the technical scope disclosed by the present invention should be covered by the protection scope of the present invention. Therefore, the protection scope of the present invention should be subject to the protection scope of the claims.
