Description

Technical Field

[0001] The invention relates to the technical field of safety protection, and in particular to a water immersion alarm system. Background Art

[0002] In the current heating system, facilities such as secondary pipe network heat exchange stations, fire pump rooms, and water pump rooms are often set up in underground closed or semi-closed spaces due to spatial layout and actual needs. Although such a layout optimizes the use of urban space to a certain extent, it also brings a series of potential safety hazards. First of all, these underground confined spaces often do not have the conditions for 24-hour personnel on duty. Due to factors such as space limitations, staffing, and operating costs, it is difficult to achieve all-weather manual monitoring around these key facilities, which means that once the equipment fails or an accident occurs, it is difficult to be discovered and handled in the first time. More seriously, when key equipment such as pipes, water pumps, and valves are damaged due to aging, wear, or external factors, a large amount of water leakage may occur. In the underground confined space, these leaked water cannot be discharged quickly, and it is easy to accumulate and submerge the equipment in a short time. This situation will not only cause direct economic losses to the equipment, but more importantly, it may further cause a series of serious secondary disasters. For example, electrical equipment is very prone to short circuits in a humid environment, which will not only damage the equipment itself, but also cause serious consequences such as fires and even explosions. In addition, the ventilation conditions in underground confined spaces are usually poor. Once flammable and explosive gases or substances leak, it is easy to form an explosive mixture, further exacerbating safety risks.

[0003] Therefore, effective monitoring and early warning measures must be taken for the heating system facilities in these underground confined spaces. The operating status of the equipment and changes in the surrounding environment can be monitored in real time. Once an abnormal situation is detected, such as rising water levels, the system should immediately send out an alarm signal so that relevant personnel can quickly take measures to deal with it. Existing monitoring systems generally rely on video monitoring, which usually has problems such as low automation and insufficient alarm accuracy. This method is not only inefficient, but also often cannot accurately determine the specific situation of flooding due to human errors. Summary of the invention

[0004] The purpose of the present invention is to provide a flood alarm system that can realize real-time monitoring of water level abnormalities. When the water level exceeds a preset threshold, the conductive movable touch plate rotates to contact the conductive static touch plate to form a circuit path, triggering the alarm to send an alarm signal. At the same time, the alarm can also send alarm information to external electronic equipment through wireless signals to alert management personnel and promptly notify management personnel to handle flooding, thereby improving the speed of emergency repairs, avoiding economic losses, and improving the safety of underground confined spaces.

[0024] The present invention provides a flood alarm system, such as Figure 1-Figure 3 As shown, the alarm 1 is included, and the alarm 1 is connected to an external power supply 3, and the external power supply 3 is used to power the alarm 1, and the external power supply 3 is preferably a 24V DC power supply. The alarm 1 is connected to a water immersion detector 2, and the water immersion detector 2 includes a hollow guide cylinder 201, and the guide cylinder 201 is made of PVC material, is non-conductive, and has a smooth inner wall. A floating member 202 is arranged in the guide cylinder 201, and the floating member 202 is preferably a cylinder made of non-conductive rubber material. The density of the floating member 202 is less than the density of water, so that the floating member 202 can move in the guide cylinder 201 when the water immersion detector 2 is immersed in water.

[0025] The water immersion detector 2 includes a base 203, the density of which is greater than the density of water, so that the water immersion detector 2 will not float even if it is submerged in water. In addition, the base 203 is made of stainless steel, which ensures the high strength and hardness of the base 203, and is not easy to rust or corrode, reducing maintenance costs and time. The base 203 includes a connected bottom plate 204 and a hollow protrusion 205, the guide cylinder 201 is fixedly connected in the protrusion 205 and protrudes from the protrusion 205, and the two sides of the protrusion 205 are symmetrically provided with first grooves 206 along the width direction of the bottom plate 204, and the two sides of the lower part of the guide cylinder 201 are symmetrically provided with second grooves 207, and the first grooves 206 correspond to the second grooves 207. In this way, the floating member 202 in the guide cylinder 201 can be exposed, and the floating member 202 is fully in contact with water to generate sufficient buoyancy for the floating member 202. The upper portion of the guide cylinder 201 is symmetrically provided with a first slot 208 and a second slot 209, and the upper portion of the guide cylinder 201 is also symmetrically provided with a first rectangular slot 210 and a second rectangular slot 211, so that the upper portion of the guide cylinder 201 forms a first convex portion 212, a second convex portion 213, a third convex portion 214 and a fourth convex portion 215, providing a connection space between the conductive moving touch plate 220 and the conductive static touch plate 221 and the guide cylinder 201. Similarly, the first rectangular slot 210 and the second rectangular slot 211 expose the floating member 202 so that the floating member 202 is fully in contact with water, and the first slot 208 and the second slot 209 provide a housing space for the conductive moving touch plate 220 and the conductive static touch plate 221.

[0026] The conductive moving touch plate 220 is arranged above the floating member 202, one end of the conductive moving touch plate 220 is a fixed end 216, and the other end is a free end 217. The fixed end 216 of the conductive moving touch plate 220 is accommodated in the first narrow groove 208, and the first pin shaft 218 is symmetrically provided on both sides of the fixed end 216, and the first protrusion 212 and the second protrusion 213 are symmetrically provided with first mounting holes 219, respectively. The first pin shaft 218 is inserted into the first mounting hole 219 and can rotate in the first mounting hole 219, and the free end 217 is accommodated in the second narrow groove 209, so that the conductive moving touch plate 220 can rotate around the first pin shaft 218 on the fixed end 216.

The third pin 224 can be plugged into the third mounting hole 225, so that both ends of the conductive static touch plate 221 are fixedly connected to the side wall of the guide cylinder 201. The conductive static touch plate 221 and the conductive dynamic touch plate 220 are made of brass, which ensures the conductive performance and corrosion resistance of the conductive static touch plate 221 and the conductive dynamic touch plate 220.

[0027] The fixed end 216 of the conductive moving touch panel 220 is connected to the moving touch panel terminal 226, and the end of the conductive static touch panel 221 corresponding to the free end 217 of the conductive moving touch panel 220 is connected to the static touch panel terminal 227. The first interface 101 on the alarm 1 is connected to the static touch panel terminal 227 through a wire, and the second interface 102 is connected to the moving touch panel terminal 226 through a wire. The free end 217 of the conductive moving touch panel 220 abuts against the floating member 202 in a natural state, that is, under the action of gravity, the free end 217 of the conductive moving touch panel 220 and the floating member 202 are in contact with each other, and the free end 217 of the conductive moving touch panel 220 and the conductive static touch panel 221 are not in contact, then the alarm 1, the conductive static touch panel 221 and the conductive moving touch panel 220 are in an open circuit state, and the alarm signal of the alarm 1 will not be turned on. When the water detector 2 is immersed in water, the buoyancy of the water will cause the floating member 202 to move upward. Under the guidance of the guide cylinder 201, the floating member 202 will push up the free end 217 of the conductive moving touch plate 220, so that the free end 217 will make an upward flipping movement around the fixed end 216. When the water level exceeds the preset threshold, the free end 217 will tightly abut against the conductive static touch plate 221, and the alarm 1, the conductive static touch plate 221 and the conductive moving touch plate 220 will form a conductive loop, and then the alarm signal of the alarm 1 will be turned on. This device uses the mechanical action between the floating member 202, the conductive static touch plate 221 and the conductive moving touch plate 220 to realize the activation of the alarm 1 signal, which will not cause jamming, false alarms and missed alarms, will not be limited by the temperature and humidity of the use environment, and has higher reliability.

[0028] The top of the alarm 1 is provided with an antenna 103, and a signal converter (not shown) is provided inside the alarm 1. The antenna 103 is used to receive or transmit signals, and the signal converter converts these signals into a format suitable for display by external electronic devices. When working, the antenna 103 will send the signal in the alarm 1 to external electronic devices, such as mobile phones, computers, etc. in real time. The alarm 1 is preferably a telephone alarm. When the water level exceeds the preset threshold, the free end 217 of the conductive moving touch plate 220 is tightly abutted against the conductive static touch plate 221, so that the alarm 1, the conductive static touch plate 221 and the conductive moving touch plate 220 form a conductive loop, and the alarm 1 will send an alarm call to the management personnel. After receiving the alarm call, the management personnel will promptly handle the flooding, thereby realizing the signal connection between the alarm 1 and the external electronic devices, and the signal transmission is safe and reliable, and is not easily interfered by the external environment, so that the management personnel can monitor the flooding alarm system in real time, improve the repair speed, avoid economic losses, and improve the safety of underground confined spaces. Moreover, the alarm 1 can be installed alone in an area with good mobile signal, suitable ambient temperature and humidity, and the water immersion detector 2 can be installed only in the area to be detected, and the length of the wire can be freely configured according to the use requirements. In addition, the device converts the water level information into the displacement information of the floating member 202, and then converts the displacement information into an electrical signal, and then converts the electrical signal into a digital signal and sends it to the electronic equipment of the manager. The signal transmission is safe, reliable and rapid, and there is no need for a dedicated person to be on duty 24 hours a day, which saves labor costs, is not affected by human factors, and improves the safety and reliability of the alarm system.

[0029] The alarm 1 is provided with a third interface 104 and a fourth interface 105. The third interface 104 is connected to the negative pole 301 of the external power supply 3 through a wire, and the fourth interface 105 is connected to the positive pole 302 of the external power supply 3 through a wire, thereby realizing the electrical connection between the alarm 1 and the external power supply 3.

[0030] In the specific application process of the water immersion alarm system provided by the present invention, the third interface 104 of the alarm 1 is connected to the negative electrode 301 of the external DC 24V power supply, and the fourth interface 105 is connected to the positive electrode 302 of the external DC 24V power supply to power the alarm 1, and the voltage between the third interface 104 and the fourth interface 105 is measured to be DC 24V to ensure the safety of electricity use. The water immersion detector 2 is placed on the ground of the area to be detected, and a preset threshold value of the water level is set in the alarm 1. At this time, the conductive moving touch plate 220 is in contact with the floating member 202, and the conductive moving touch plate 220 and the conductive static touch plate 221 are in an open circuit state. When there is water in the detection area, as the water depth increases, the floating member 202 will move upward under the buoyancy of the water. Under the guidance constraint of the guide cylinder 201, the floating member 202 will push the free end 217 of the conductive moving touch plate 220 upward, so that the conductive moving touch plate 2 The free end 217 of 20 makes an upward flipping motion around the fixed end 216 until it is in close contact with the conductive static touch plate 221, so that the conductive moving touch plate 220 and the conductive static touch plate 221 are in a conductive state, so that the alarm 1, the conductive static touch plate 221 and the conductive moving touch plate 220 form a conductive loop. At this time, the water level reaches the preset threshold value, and the signal will trigger the alarm signal of the alarm 1. Through the conversion of the signal converter, the signal is sent to the manager's mobile phone in the form of an alarm phone, realizing a remote telephone alarm.

[0031] It should be noted that the water immersion alarm system in this embodiment is not limited to the detection of water level, but can also be applied to the detection of other liquids. When detecting other liquids, it is only necessary to ensure that the density of the floating part 202 of the water immersion detector 2 is less than the density of the detected liquid, and the density of the base 203 is greater than the density of the detected liquid, so that the liquid level detection alarm can be performed on other detected liquids.

[0032] The present invention uses specific examples to illustrate the principles and implementation methods of the present invention. The above examples are only used to help understand the method and core ideas of the present invention. At the same time, for those skilled in the art, according to the ideas of the present invention, there will be changes in the specific implementation methods and application scopes. In summary, the content of this specification should not be understood as limiting the present invention.
