Description

Technical Field

[0001] The utility model relates to the technical field of drainage, and particularly discloses a pump room water flooding automatic alarm drainage system. Background Art

[0002] In high-rise buildings, the secondary water supply pump room is an important part of the water supply system, mainly used to store and transport water resources. However, in actual use, the pump room may be flooded due to pipe rupture, equipment failure or other reasons, causing the equipment in the pump room to be soaked, seriously affecting its normal operation, and even causing equipment damage and economic losses. Therefore, how to effectively monitor and promptly deal with the flooding problem in the pump room has become an important issue to ensure the safety and normal operation of the pump room.

[0003] In the prior art, although there are some devices and systems for monitoring and treating flooding in pump rooms, there are still many deficiencies. For example, traditional flooding monitoring systems usually rely on manual inspections, which are inefficient and have a certain lag. In addition, although some existing automatic alarm systems can send out alarm signals when flooding occurs, due to the lack of effective sound insulation measures, the alarm sound is often interfered by other noises in the pump room, affecting the alarm effect and the timely response of the staff. An existing automatic drainage system and method (publication number: CN113202555B) has at least the following disadvantages:

[0004] 1. The existing drainage system requires staff to regularly check the water accumulation in the pump room, which is time-consuming and labor-intensive. When the inspection frequency is low, the flooding problem may not be discovered in time. Once the pump room is flooded, it is usually necessary to rely on manual activation of the drainage equipment, which has a slow response speed and may cause the equipment to be damaged in the accumulated water. Therefore, a device that can provide alarm and automatic drainage is urgently needed.

[0005] 2. In the existing drainage system, there is no effective isolation measure for the vibration generated by the equipment in the pump room during operation, which easily affects the accuracy of the liquid level sensor and alarm device. The equipment is also exposed to the pump room environment and is affected by factors such as dust and moisture. The annual failure rate of the water pump is high, so a device that can reduce noise and prevent dust is urgently needed. Utility Model Content

[0006] The main purpose of the utility model is to provide an automatic alarm and drainage system for water flooding in a pump room, which can effectively solve the problems in the background technology.

[0007] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: an automatic alarm and drainage system for water flooding in a pump room, comprising a soundproof cover, a handle is installed above the soundproof cover, a support column is installed below the soundproof cover, an alarm device is installed above the soundproof cover, a water pump is installed inside the soundproof cover, a drainage pipe is installed on the left side of the water pump, a suction pipe is installed below the water pump, and a control device is installed above the inside of the soundproof cover.

[0008] Preferably, a connecting column is installed on the right side of the control device, and a liquid level sensor is installed below the connecting column.

[0009] Preferably, a power supply is installed inside the control device.

[0010] Preferably, the wires extend out from the left side of the power supply.

[0011] Preferably, a controller is installed on the other side of the electric wire.

[0012] Preferably, an alarm module is installed on the left side of the controller.

[0013] Compared with the prior art, the utility model has the following beneficial effects:

[0014] 1. The utility model installs an alarm device and a liquid level sensor. When the liquid level sensor detects flooding, the system can automatically trigger the alarm device, emit an audible and visual alarm, and promptly remind the staff to handle it. This automatic alarm function can greatly reduce the frequency and intensity of manual inspections. Compared with traditional manual monitoring and alarm methods, the automatic alarm system can respond to flooding in the first place, reducing the time to discover and handle flooding problems and improving the overall response speed and efficiency of the system.

[0015] 2. The utility model installs a soundproof cover, which can effectively isolate the environmental noise in the pump room, ensure that the sound and light alarm signals emitted by the alarm device can be clearly received in the pump room, reduce the interference of external noise on the alarm signal, and can effectively isolate dust, greatly increasing the utilization rate of the equipment.

[0023] Example

[0024] See also Figure 1-2 , the utility model provides a technical solution:

[0025] The automatic alarm and drainage system for water flooding in the pump room comprises a soundproof cover, a handle is installed on the top of the soundproof cover, a support column is installed on the bottom of the soundproof cover, an alarm device is installed on the top of the soundproof cover, a water pump is installed inside the soundproof cover, a drainage pipe is installed on the left side of the water pump, a suction pipe is installed below the water pump, a control device is installed on the top of the inside of the soundproof cover, a connecting column is installed on the right side of the control device, a liquid level sensor is installed below the connecting column, a power supply is installed inside the control device, an electric wire extends from the left side of the power supply, a controller is installed on the other side of the electric wire, and an alarm module is installed on the left side of the controller.

[0026] The liquid level sensor described in this embodiment preferably adopts the WLD2 series liquid level sensor produced by Honeywell. The WLD2 series liquid level sensor has high-precision water level detection capability and can accurately detect water level changes of several millimeters. The sensor can respond quickly when the water level changes to ensure timely alarm.

[0027] It should be noted that the traditional method of the utility model requires staff to regularly check the water level in the pump room. Assuming that the staff checks once every 4 hours, if a flooding problem occurs during the inspection interval, it may take 4 hours to be discovered. The liquid level sensor of the utility model can detect the water level once a second. Once the water level is detected to exceed the preset height, a signal is immediately sent to trigger the alarm device to achieve a second-level response. For example, when the liquid level sensor detects that the water level exceeds 5 cm, an alarm is sounded within 5 seconds to alert the staff. The noise level in the pump room is set to 80 decibels (dB). The alarm response time of the prior art and the utility model in a noisy environment is tested separately. Prior art: Under noise interference, the alarm response time of the alarm device is an average of 12 seconds. In some test cases, the alarm sound is completely covered, resulting in the failure to issue an alarm signal in time. The utility model: Due to the effective sound insulation effect of the soundproof cover, the alarm response time of the alarm device is significantly shortened, with an average response time of 2 seconds, and the alarm signal can be clearly conveyed in all test cases. Prior art: Since the equipment is exposed to the pump room environment and is affected by dust, moisture and other factors, the annual failure rate of the alarm device and the water pump is 15%, and maintenance and replacement of parts are required many times a year. The utility model: Through the protection of the equipment by the soundproof cover, the annual failure rate is significantly reduced to 3%, and the frequency of equipment maintenance and replacement of parts is reduced by 80%, saving a lot of maintenance costs.

[0028] It should be noted that the following is a comparison table of experimental data between the utility model and the traditional equipment:

[0029]

[0030]

[0031] When the amount of water in the pump room is large and the speed of the water inflow is greater than the discharge capacity of the pump, the water in the pump room will accumulate quickly, and the rising water level will submerge the entire drainage system, causing the internal control device to fail and affect normal drainage. Figure 3 As shown, the support column 5 includes a support sleeve 15 fixed on the ground, and a vertical rod 16 is installed in the support sleeve 15. The vertical rod 16 is fixedly installed under the sound insulation cover 1. Both sides of the sound insulation cover 1 are provided with buoyancy boxes 17. The buoyancy of the buoyancy boxes 17 can drive the sound insulation cover 1 and the vertical rod 16 to move upward relative to the support sleeve 15.

[0032] With the arrangement of the above structure, after water accumulates in the pump room, the buoyancy box 17 will drive the sound insulation cover 1 and the water pump 8 inside to float upward together, and the vertical rod 16 will move upward along the supporting sleeve 15, so that the accumulated water will not affect the normal use of the internal control device 9, and the suction pipe 6 is guaranteed to be below the water surface. The drain pipe 4 can be connected to the hose. No matter to which height the sound insulation cover 1 floats, the hose is always kept connected to the drain port to ensure normal drainage operation.

[0033] As high-rise residential buildings in cities are continuously put into use, the management scale of secondary water supply pump rooms is constantly increasing. The traditional inspection-based management and emergency response methods are laborious and time-consuming, and many problems are exposed during operation, which cannot meet the current needs of water supply safety. Therefore, it is necessary to reduce the workload of secondary water supply inspectors through intelligent management methods.

[0034] Take Jinan as an example: According to statistics, the maintenance and inspection workload of the secondary water supply pump room in the urban area in 2021 was close to 1,500 times, with a cost of about 900,000 yuan; due to equipment failure, external line power outage, front-end voltage reduction, pipeline leakage and other problems, the water outage and voltage reduction emergency repair workload was close to 100 times, and the maintenance work also reached about 300 times, with a cost of about 460,000 yuan. After analysis and refined inspection, some equipment sudden leakage failures can be temporarily handled by automatic emergency response equipment, and emergency discharge can be implemented for sudden leakage, thereby protecting the internal equipment of the pump room.

[0035] Jinan Water Group completed the construction of the secondary water supply pump room monitoring and management platform in 2016. The existing system was independently developed by the group's subsidiary Puli Electric Control Company. The group has complete intellectual property rights and core technologies, which has laid a good working foundation for subsequent intelligent upgrades and renovations. The existing monitoring and management system has completed the detection of operating status signals of major equipment, including all unit equipment, valve equipment, fan equipment, sewage pump equipment, etc. in the pump room; the system collects all operating instrument data, including pressure signals, flow signals, and some power distribution data signals. The automatic control system also has an unattended remote control function. The entire system is relatively complete, providing strong data support for smart inspections. The pump room flooding automatic alarm and drainage system provided in this application is an effective supplement to the emergency response function in the existing automatic control system.

Those skilled in the art should understand that the utility model is not limited by the above embodiments.
