Description

Technical Field

[0001] The utility model relates to the field of water conservancy engineering equipment, in particular to a flood alarm system for a pump room. Background Art

[0002] With the development of modern urbanization, the number of floors of modern residential buildings is generally more than 10. In order to supply tap water from the water plant to each household user, multiple pump rooms are equipped in each residential area or even each residential building. The pump room is equipped with water tanks, water pumps, etc. Since various abnormalities often occur in the pump room, leading to flooding problems, it is essential to equip the pump room with a flood alarm device.

[0003] like Figure 1 and Figure 2 As shown, currently the pump room generally includes two flood alarms, which are connected to the control cabinet respectively. The flood alarm A and the flood alarm B are placed at different heights through the bracket. The flood alarm B is placed at a low position, and the flood alarm A is placed at a high position, generally 20 cm high. At present, the two conventional flood alarms are both electrical sensor alarms. The principle of electrical sensing is that when the water level does not exceed the threshold, the electrical contacts of the flood alarm are in a closed state, and the current can pass through. When the water level exceeds the threshold, the water will trigger the built-in leakage rope or float and other sensing elements of the flood alarm, causing the electrical contacts to be disconnected and the circuit to no longer be connected. At this time, the flood alarm will trigger an alarm. When there is a small amount of water flooding in the pump room, the flood alarm B will alarm when it is flooded, but at this time, the flood alarm A will not alarm because it has not come into contact with water, and the water pump will operate normally, reminding the operation and maintenance personnel to come for repairs; when the water level in the pump room is very high, such as abnormal flooding or when the operation and maintenance personnel fail to repair in time, the water level is relatively high, and the flood alarm A will come into contact with water. At this time, both the flood alarm B and the flood alarm A will alarm, and when both the flood alarm A and the flood alarm B alarm, another instruction needs to be implemented, that is, the control cabinet must issue a pump stop instruction, and the pump room will stop water. In other words, the flood alarm system needs to implement two functions. The first is that when the water level in the pump room is low, it only alarms but does not stop the pump, reminding the operation and maintenance personnel to repair; the second is that when the water level in the pump room is high, the pump is stopped directly.

[0004] The existing flood alarm system has a problem that a separate bracket needs to be made to fix the flood alarm A and the flood alarm B at different heights, and the flood alarm A and the flood alarm B often fall to the ground. At this time, when there is a small amount of flooding in the pump room, the flood alarm A and the flood alarm B will alarm at the same time, causing the pump to stop abnormally. In addition, the production of the fixing bracket is relatively complicated, and it is necessary to drill holes in the ground to fix it. Summary of the invention

[0008] The water level sensing unit includes a microprocessor and a first sensor and a second sensor connected to the microprocessor. The first sensor is an electronic water level sensor, which sends a first sensor signal to the microprocessor when it contacts water; the second sensor is a pressure water level sensor, which sends a second sensor signal to the microprocessor when it contacts water and the pressure value of the water is greater than or equal to the set pressure value; the microprocessor can be used to receive the first sensor signal and the second sensor signal, and when it receives the first sensor signal and the second sensor signal, it sends a corresponding first alarm signal and a second alarm signal to the control unit respectively.

Preferably, the set pressure value is greater than or equal to 1000 Pa, and more preferably 1000-3000 Pa, for example, 1000 Pa, 2000 Pa (corresponding to the pressure at a water depth of 20 cm), and 3000 Pa.

[0015] Preferably, the water level sensing unit also includes a first indicator light and a second indicator light connected to the microprocessor, and the first indicator light and the second indicator light are controlled by the microprocessor. When the microprocessor receives the first sensor signal and the second sensor signal, the first indicator light and the second indicator light are controlled to flash respectively, and when the first indicator light and the second indicator light flash, light of different colors are emitted.

[0016] In some implementations, the first indicator light emits yellow light when flashing.

[0017] In some implementations, the second indicator light emits red light when flashing.

[0018] Preferably, the alarm issued by the alarm unit includes one or more of an audible and visual alarm, a communication alarm, and an image alarm.

[0019] The present invention also provides a flood alarm device, which includes a base and a water level sensor unit that can be communicatively connected to a control unit. The water level control unit is installed on the base and includes a microprocessor and a first sensor and a second sensor connected to the microprocessor.

[0020] The first sensor is an electronic water level sensor, which sends a first sensing signal to the microprocessor when it contacts water;

[0021] The second sensor is a pressure water level sensor, which sends a second sensing signal to the microprocessor when it contacts water and the pressure value of the water is greater than or equal to the set pressure value;

[0022] The microprocessor can be used to receive the first sensor signal and the second sensor signal, and when it receives the first sensor signal and the second sensor signal, it sends the corresponding first alarm signal and second alarm signal to the control unit respectively.

[0023] Preferably, the base is made of stainless steel.

[0024] Further preferably, the base is in the shape of a flat plate.

[0025] Preferably, the water level sensing unit also includes a first indicator light and a second indicator light connected to the microprocessor, and the first indicator light and the second indicator light are controlled by the microprocessor.

Of course, they are only examples and are not intended to limit the embodiments of the present invention. In addition, the embodiments of the present invention may repeat reference numbers and / or reference letters in different examples, and such repetition is for the purpose of simplicity and clarity, and does not itself indicate the relationship between the various embodiments and / or settings discussed.

[0046] The utility model is further described below in conjunction with the embodiments shown in the accompanying drawings.

[0047] Example 1

[0048] A flood alarm system for a pump room comprises a control unit 2, a water level sensor unit 1, an alarm unit (not shown in the drawings) and a power supply (not shown in the drawings). The power supply is electrically connected to the control unit 2, the water level sensor unit 1 and the alarm unit for powering on.

[0049] The water level sensing unit 1 includes a microprocessor 13 , a first sensor 11 and a second sensor 12 .

[0050] The first sensor 11 is connected to the microprocessor 13 for communication. It is an electronic water level sensor. When it touches water, it sends a first sensor signal to the microprocessor 13. Specifically, it can be an electronic water level sensor of the NOHKEN FM-24 model of Japan. Of course, it can also be an electronic water level sensor of other models in the field. This application does not make specific restrictions. The second sensor 12 is also connected to the microprocessor 13 for communication. It is a pressure water level sensor. When it touches water and the pressure value of the water is greater than or equal to the set pressure value, it sends a second sensor signal to the microprocessor 13. The set pressure value is usually ≥1000 Pa. In practice, the set pressure value is 2000 Pa, which corresponds to the pressure of 20 cm water depth. The pressure water level sensor can be a pressure water level sensor of the SEBADS (T) 22 model of Germany. Of course, it can also be an electronic water level sensor of other models in the field. This application does not make specific restrictions. The microprocessor 13 can be used to receive the first sensor signal and the second sensor signal, and is connected to the control unit 2 in communication. When it receives the first sensor signal and the second sensor signal, it sends corresponding alarm signals to the control unit 2, that is, when it receives the first sensor signal, it sends the first alarm signal to the control unit 2, and when it receives the second sensor signal, it sends the second alarm signal to the control unit 2. The microprocessor can refer to the prior art, and the present application does not make specific limitations.

[0051] The alarm unit is controlled by the control unit 2. When the control unit 2 receives the first alarm signal and the second alarm signal, the control unit 2 controls the alarm unit to issue a corresponding alarm, which includes but is not limited to one or more of an audible and visual alarm, a communication alarm, and an image alarm, to remind the on-duty personnel to repair the vehicle. When the control unit 2 receives the second alarm signal, in addition to controlling the alarm unit to issue an alarm, it also controls the pump room water pump 3 to stop the pump.

[0052] Since two different types of sensors, electronic water level sensor and pressure water level sensor, are used, the two sensors can be directly placed on the ground 4 of the pump room, and the positions can be flexibly changed. When the water level is low and when the water level is high, the two sensors can send sensing signals respectively, which can meet the actual needs and be more convenient to use. At the same time, it avoids the situation that the electronic sensor at a high position falls when only the electronic water level sensor is used in the prior art, causing the pump to stop abnormally. In addition, the method of the present application eliminates the existing bracket fixation. The production of the fixed bracket is relatively complicated, and it needs to be fixed by drilling holes in the ground, etc., which is more convenient for installation and use. Compared with the existing flood alarm system, it has a great improvement in both economic and operational aspects.

[0053] Example 2

[0054] This embodiment is substantially the same as the embodiment 1, except that the water level sensor unit 1 further includes a base 16 and an indicator light.

[0055] like Figures 3 to 6 As shown, the first sensor 11, the second sensor 12, and the microprocessor 13 are detachably mounted on the base 16, and the base 16 is preferably in the shape of a plate. The plate-shaped base 16 firstly ensures that the first sensor 11 and the second sensor 12 are in the same horizontal plane; secondly, it can be closely attached to the pump room floor 4. Preferably, the base 16 is made of stainless steel, which is heavy, and can ensure that the water level height sensor unit 1 will not float on the water when flooding occurs, but always fits with the floor 4, thereby ensuring that the first sensor 11 and the second sensor 12 smoothly send corresponding sensor signals.

[0056] The indicator light is also mounted on the base 16, and the specific position is not limited. The indicator light includes a first indicator light 14 and a second indicator light 15 connected to the microprocessor 13. The first indicator light 14 and the second indicator light 15 are controlled by the microprocessor 13. When the microprocessor 13 receives the first sensor signal, the first indicator light 14 is controlled to flash; when the microprocessor 13 receives the second sensor signal, the second indicator light 15 is controlled to flash to remind the on-duty personnel that the pump room is flooded. Preferably, the first indicator light 14 and the second indicator light 15 emit different colors of light when flashing. In this embodiment, the first indicator light 14 emits yellow light when flashing, and the second indicator light 15 emits red light when flashing.

[0057] The working principle of this embodiment is as follows:

[0058] When the first sensor 11 contacts water, it sends a first sensing signal to the microprocessor 13. The microprocessor 13 receives the first sensing signal and sends a first alarm signal to the control unit 2. At the same time, it controls the first indicator light 14 to flash. The control unit 2 receives the first alarm signal and controls the alarm unit to sound an alarm to remind the staff to perform maintenance.

[0059] When the second sensor 12 contacts water and the water pressure exceeds the set pressure value, a second sensing signal is sent to the microprocessor 13. The microprocessor 13 receives the second sensing signal and sends a second alarm signal to the control unit 2, while controlling the second indicator light 15 to flash. The control unit 2 receives the second alarm signal, controls the alarm unit to sound an alarm and stop the pump.

[0060] The above embodiments are only for illustrating the technical concept and features of the utility model, and their purpose is to enable people familiar with the technology to understand the content of the utility model and implement it accordingly, and they cannot be used to limit the protection scope of the utility model. Any equivalent changes or modifications made according to the spirit of the utility model should be included in the protection scope of the utility model.
