The safe operation of these equipment is crucial to ensuring social stability and people's lives. However, fire accidents of power equipment occur from time to time, which not only poses a serious threat to the safety and stable operation of the power grid, but also may cause significant property losses and casualties.

[0003] Although the existing fire prevention devices for power equipment can detect abnormal temperature in the power equipment in time, it is difficult to change the air component content in the power equipment according to the abnormal temperature change. When the neutral point displacement phenomenon occurs in the power equipment, it causes asymmetric distribution of various load voltages, which may increase the no-load loss and heat of the power equipment. When the phenomenon causes abnormal temperature, the existing fire prevention devices are difficult to prevent fire or suppress fire in time by changing external natural factors.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] See also Figures 1 to 9The present invention provides a technical solution: a fire prevention device for intelligent power monitoring, comprising a sensor module for detecting fire conditions and a terminal module for remotely monitoring the power equipment, the power equipment comprising a cabinet 1 for protecting its internal components and a heat dissipation fan for dissipating hot air in the cabinet 1, the cabinet 1 is provided with a heat-resisting structure for changing the oxygen content of the air therein according to the temperature change therein;

[0040] The heat-resisting structure includes a base 2 that moves in a horizontal direction according to the temperature change in the cabinet 1. A horizontal sliding groove for the base 2 to slide is provided on the cabinet 1. A hopper 11 for accommodating sodium bicarbonate particles and a receiving frame 18 for accommodating acetic acid solution are provided at one end of the base 2 away from the cabinet 1. It should be noted that although in the embodiments of the present application, the hopper 11 contains sodium bicarbonate particles and the receiving frame 18 contains acetic acid solution, according to the concept of the present application, the sodium bicarbonate particles can be replaced by other substances that generate flame-retardant gases such as carbon dioxide after heating, and correspondingly, the acetic solution can also be replaced by a substance that generates flame-retardant gases such as carbon dioxide after reacting with the substance in the hopper 11.

[0041] The internal space of the hopper 11 includes a first chamber 111 and a second chamber 112 which are not connected to each other, and a prevention component for driving the sodium bicarbonate particles in the first chamber 111 to be exposed to the outside is provided on the base 2;

[0042] The heat-resisting structure also includes a concentrated gas component for driving the sodium bicarbonate particles in the first chamber 111 and the second chamber 112 to mix with the acetic acid solution. The base 2 is also provided with a closing component for disconnecting the power supply of the cooling fan when the concentrated gas component is running.

[0043] like Figure 1-Figure 3 As shown, the base 2 arranged in the cabinet 1 can move freely in the horizontal direction according to the temperature change therein, wherein when the temperature in the cabinet 1 reaches a first threshold value, the horizontal movement process of the base 2 can drive the hopper 11 and the receiving frame 18 to move synchronously in the horizontal direction, wherein the hopper 11 has a first compartment 111 and a second compartment 112 which are independent of each other, sodium bicarbonate particles are placed in the hopper 11, and acetic acid solution is received in the receiving frame 18.

[0044] At the same time, in a three-phase circuit, if the three-phase load is symmetrical, the voltage at the neutral point is zero, but if the three-phase load is asymmetrical, and there is no neutral line or the neutral line impedance is large, then a voltage will appear at the neutral point. This phenomenon is called the neutral point displacement phenomenon, wherein the neutral point displacement may cause the generation of zero-sequence current, which will increase the no-load loss and heat generation of the system, thereby causing the temperature of the power equipment to rise abnormally. After the temperature reaches the first threshold, the sodium bicarbonate particles in the first compartment 111 fall into the receiving frame 18, but will not contact the acetic acid solution in the receiving frame 18, so that the sodium bicarbonate particles at the falling point can be prevented from reacting with the acetic acid solution, wherein the sodium bicarbonate particles are exposed to the high-temperature air in the cabinet 1, so that the sodium bicarbonate particles are naturally decomposed at a higher temperature. The following is the chemical equation of the decomposition process of sodium bicarbonate:

[0045] 2NaHCO3→Na2CO3+H2O+CO2

[0046] Among them, the chemical formula of sodium bicarbonate is NaHCO3. Sodium bicarbonate needs to be heated during the decomposition process. Therefore, when the temperature reaches the first threshold value, it is regarded as an abnormal temperature rise in the power equipment. Based on this abnormal situation, the power equipment may have a fire phenomenon as the temperature rises subsequently. Therefore, at this time, the sodium bicarbonate particles in the first compartment 111 are exposed to the air in the cabinet 1. The decomposition process of the sodium bicarbonate particles at the first threshold temperature is used to increase the carbon dioxide content in the cabinet 1, and then the gas composition ratio in the cabinet 1 is changed in advance, thereby achieving the purpose of preventing the occurrence of fire in advance.

[0047] At the same time, if the temperature inside the power equipment gradually rises or the internal temperature reaches the second threshold value when a fire occurs, at this time, the sodium bicarbonate granules in the second compartment 112 fall into the receiving frame 18, and are simultaneously mixed with the acetic acid solution together with the sodium bicarbonate granules that previously entered the receiving frame 18, wherein the sodium bicarbonate granules react chemically with the acetic acid solution and further produce carbon dioxide, and the chemical formula is as follows:

[0048] CH3COOH+NaHCO3→CH3COONa+H2O+CO2

[0049] Among them, the chemical formula of acetic acid is CH3COOH, and the volume size of the first compartment 111 is smaller than the volume size of the second compartment 112. When the temperature reaches a second threshold value higher than the first threshold value, it is considered that the electrical equipment has or is about to have a fire phenomenon. At this time, more carbon dioxide gas is produced through the chemical reaction between the sodium bicarbonate particles and the acetic acid solution, thereby further increasing the carbon dioxide concentration in the cabinet 1, thereby further suppressing the occurrence of fire or suppressing the fire by reducing the oxygen content in the cabinet 1 when a fire occurs.

[0050] At the same time, when the temperature reaches the second threshold, the closing component can be driven to operate, wherein the closing component can cut off the circuit where the cooling fan is located, thereby causing the circuit where the cooling fan is located to be in an open circuit phenomenon, thereby helping to control the airflow in the cabinet 1, reducing the connectivity between the outside natural air and the gas in the cabinet 1, and reducing the escape velocity of the gas with a high carbon dioxide concentration in the cabinet 1, and reducing the oxygen supply in the cabinet 1, thereby effectively suppressing the fire.

[0051] In one of the more preferred embodiments, the prevention component includes a middle partition 12 fixedly connected to the inner wall of the hopper 11, the middle partition 12 divides the internal space of the hopper 11 into a first compartment 111 and a second compartment 112, and a positioning plate 15 is provided below the hopper 11, and the positioning plate 15 is fixedly connected to the cabinet 1;

[0052] The middle partition plate 12 is provided with a first hatch 13 which is rotatably fixed to the first cabin 111, and the positioning plate 15 is provided with a first material discharge chute 16 which is provided at a position corresponding to the first hatch 13, and the horizontal cross-sectional dimension of the first material discharge chute 16 is larger than the horizontal cross-sectional dimension of the first hatch 13;

[0053] The receiving frame 18 is provided with a transverse sealing plate 19 for receiving the sodium bicarbonate particles in the first chamber 111 .

[0054] like Figure 2 , Figure 3 , Figure 5 and Fig. 9 As shown, when the temperature in the cabinet 1 reaches the first threshold value, the hopper 11 and the receiving frame 18 move synchronously in the horizontal direction, wherein the first hatch 13 arranged below the hopper 11 moves to the position of the first discharge chute 16, and a torsion spring No. 1 is provided between the first hatch 13 and the middle partition 12 to drive the first hatch 13 to return to its initial position. Therefore, when the first hatch 13 corresponds to the position of the first discharge chute 16, the first hatch 13 is in an open state under the action of the torsion spring, so that the sodium bicarbonate particles in the first chamber 111 fall onto the horizontal sealing plate 19 arranged on the receiving frame 18 under the action of gravity, wherein the horizontal sealing plate 19 is used to block the open end of the receiving frame 18, and its purpose is to enable the acetic acid solution in the receiving frame 18 to be stored in a relatively sealed condition, and to receive the sodium bicarbonate particles in the first chamber 111 and prevent them from contacting with the acetic acid solution.

[0055] At the same time, the sodium bicarbonate particles that fall onto the horizontal sealing plate 19 are decomposed under the action of the internal temperature of the electrical equipment and produce carbon dioxide gas, thereby increasing the carbon dioxide concentration of the gas in the cabinet 1. It should be noted that in actual use, the positions of the hopper 11 and the receiving frame 18 in the cabinet 1 need to be relatively far away from the position of the cooling fan to prevent the operation of the cooling fan from directly leading the carbon dioxide gas generated by the thermal decomposition of the sodium bicarbonate particles into the outside natural air. At the same time, when the temperature is at the first threshold, although the operation of the cooling fan will partially affect the rising process of the carbon dioxide concentration in the cabinet 1, the decomposition process of the sodium bicarbonate particles can still increase the carbon dioxide concentration in the cabinet 1, thereby changing the gas content in the cabinet 1 in advance when the temperature of the power equipment is abnormal, thereby achieving the purpose of preventing fire.

[0056] Based on the prevention component embodiment, the concentrated gas component includes a second hatch 14 arranged on the hopper 11, the second hatch 14 is fixedly rotated on the middle partition 12 and corresponds to the position of the second chamber 112, and the positioning plate 15 is corresponding to the position of the second hatch 14 and has a second discharge chute 17 with a horizontal cross-sectional size larger than the second hatch 14;

[0057] The inner wall of the cabinet 1 is fixedly connected with a circular frame 20 , on which a groove body 1 is provided for the object receiving frame 18 to slide horizontally, and a delivery component for driving the horizontal sealing plate 19 to separate from the object receiving frame 18 is provided.

[0058] The delivery assembly includes an L-shaped baffle plate 21 fixedly connected to the circular frame 20, and the middle part of the receiving frame 18 includes a closing portion 181. The closing portion 181 is provided with a rectangular through groove for the horizontal sealing plate 19 to slide horizontally and frictionally. The side of the horizontal sealing plate 19 away from the closing portion 181 includes an end extension portion 191 that is integrally formed and corresponds to the position of the L-shaped baffle plate 21.

[0059] like Figure 2 , Figure 3 , Figure 5 and Figure 6 As shown, when the temperature of the power equipment reaches the second threshold value, the hopper 11 and the receiving frame 18 will move in the horizontal direction again until the second hatch 14 on the hopper 11 corresponds to the second discharge chute 17. The second hatch 14 is provided with a No. 2 torsion spring that drives it to deflect to the initial position. Therefore, the second hatch 14 will be in an open state when it corresponds to the second discharge chute 17.

[0060] At the same time, when the receiving frame 18 moves toward the second material discharge chute 17, the end extension 191 of the horizontal sealing plate 19 gradually approaches and contacts the L-shaped blocking plate 21, wherein, under the action of the L-shaped blocking plate 21, the horizontal sealing plate 19 cannot continue to move in the horizontal direction, and thus the horizontal sealing plate 19 can no longer block the closing portion 181 of the receiving frame 18. In the subsequent horizontal movement of the receiving frame 18, the sodium bicarbonate particles on the horizontal sealing plate 19 fall into the acetic acid solution in the receiving frame 18.

[0061] Among them, when the receiving frame 18 corresponds to the second material discharge chute 17, the hopper 11 moves toward the second material discharge chute 17 until the second hatch 14 is in an open state. At this time, the sodium bicarbonate particles in the second compartment 112 fall directly into the acetic acid solution under the action of gravity, and then a chemical reaction occurs between the two to produce carbon dioxide gas, thereby increasing the carbon dioxide content in the cabinet 1, achieving the purpose of changing the gas environment and preventing or suppressing the fire.

[0062] It should be noted that although the transverse sealing plate 19 slides through the closing portion 181 through the rectangular through groove, there is a certain friction between the transverse sealing plate 19 and the closing portion 181. Therefore, when the receiving frame 18 moves in the horizontal direction, it can drive the transverse sealing plate 19 to move horizontally synchronously until the transverse sealing plate 19 is blocked by the L-shaped blocking plate 21, and then it will gradually separate from the closing portion 181. The purpose is to ensure that when the temperature of the power equipment reaches the first threshold value, when the receiving frame 18 moves horizontally to the corresponding position of the first discharge chute 16, the transverse sealing plate 19 can block the closing portion 181 to prevent the sodium bicarbonate particles in the first compartment 111 from entering the acetic acid solution.

[0063] Furthermore, a memory alloy 3 that deforms according to a temperature threshold is provided at one end of the base 2 facing the cabinet 1, a side ear plate 5 is fixedly connected to the base 2, and both ends of the memory alloy 3 are respectively fixedly connected to the cabinet 1 and the side ear plate 5, and a horizontal sliding seat 4 is provided above the base 2 and a groove body 2 for horizontal sliding is provided;

[0064] The base 2 is fixedly connected with a connecting column 22 , and one end of the connecting column 22 away from the base 2 is fixedly connected to the receiving frame 18 . The end of the horizontal sliding seat 4 facing the positioning plate 15 includes an extension portion 401 , and the hopper 11 is fixedly connected to the extension portion 401 .

[0065] The base 2 is fixedly connected with a stop block 8, and the side of the horizontal sliding seat 4 facing the stop block 8 is fixedly connected with a guide column 6, the guide column 6 slides through the stop block 8, and the outer ring of the guide column 6 is fixedly sleeved with a return spring 7, and the two ends of the return spring 7 are respectively fixedly connected to the stop block 8 and the horizontal sliding seat 4;

[0066] A swing rod 9 that deflects in the vertical direction is provided above the transverse sliding seat 4, and the lower surface of the swing rod 9 includes a triangular portion 901. The transverse sliding seat 4 is fixedly connected with a co-position block 10 at a position corresponding to the triangular portion 901. The end of the swing rod 9 away from the transverse sliding seat 4 is fixedly connected with a transverse column 23, and a side support plate 24 is fixedly connected to the cabinet body 1. The transverse column 23 rotates on the side support plate 24 on a fixed axis.

[0067] like Figure 2 , Figure 3 , Figure 4 and Figure 7 As shown, when the temperature of the electrical equipment reaches the first threshold value, the memory alloy 3 undergoes the first deformation, thereby driving the base 2 to move in the horizontal direction, wherein a transverse sliding seat 4 is provided on the base 2, and a reset spring 7 is provided between the transverse sliding seat 4 and a stop block 8 fixedly arranged on the base 2, and the same position block 10 on the transverse sliding seat 4 is not in contact with the triangular portion 901 at this time, therefore, when the memory alloy 3 is deformed for the first time, the transverse sliding seat 4 and the base 2 can move synchronously in the horizontal direction.

[0068] Among them, the horizontal sliding seat 4 is fixedly connected to the hopper 11, and at the same time, the base 2 is fixedly connected to the receiving frame 18 through the connecting column 22. Therefore, the hopper 11 and the receiving frame 18 can move synchronously when the temperature is at the first threshold value, and move to the position corresponding to the first discharge trough 16 on the positioning plate 15.

[0069] At the same time, when the temperature of the power equipment reaches the second threshold value, the memory alloy 3 can undergo secondary deformation, thereby driving the base 2 to continue to move in the horizontal direction. During the horizontal movement of the horizontal sliding seat 4, the same position block 10 and the triangular portion 901 on the swing rod 9 will conflict with each other. Therefore, under the restriction of the swing rod 9, the horizontal sliding seat 4 cannot move synchronously with the base 2, and the reset spring 7 gradually undergoes compression deformation. At this time, the base 2 drives the fixedly connected receiving frame 18 to move toward the second unloading trough 17 first;

[0070] At the same time, as the base 2 continues to move, the stop block 8 contacts the end of the swing rod 9, and the contact surfaces of the stop block 8 and the swing rod 9 are both inclined surfaces. Therefore, as the stop block 8 moves horizontally, the swing rod 9 deflects under the restriction of the stop block 8. When the swing rod 9 deflects, the triangular portion 901 disengages from the same position block 10. At this time, the reset spring 7 restores its elastic deformation and drives the hopper 11 to move toward the second discharge chute 17.

[0071] During actual use, the base 2 first drives the receiving frame 18 to move horizontally to the position of the second feed chute 17, and during this movement, by limiting the movement of the horizontal sealing plate 19, the sodium bicarbonate particles on the horizontal sealing plate 19 fall into the acetic acid solution first. Secondly, the horizontal sliding seat 4 drives the hopper 11 to move to the corresponding position of the second feed chute 17, and at this position, the second hatch 14 is opened, and then the sodium bicarbonate particles in the second compartment 112 fall into the acetic acid solution under the action of gravity.

[0072] It should be noted that the swing rod 9 is rotated on the side support plate 24 through the transverse column 23, wherein a No. 3 torsion spring is provided between the transverse column 23 and the side support plate 24. Under the action of the No. 3 torsion spring, the swing rod 9 is driven to always deflect toward one side of the transverse sliding seat 4 when not affected by external forces. At the same time, the torsion spring in this article is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure.

[0073] On the basis of the embodiment of the concentrated gas component, the closing component includes a ratchet rod 25 coaxially fixed with the horizontal column 23, a vertical plate 26 is fixedly connected to the inner wall of the cabinet 1, and a positioning copper plate 27 and a movable copper plate 28 are provided on the vertical plate 26. The positioning copper plate 27 is fixedly connected to the vertical plate 26, and the movable copper plate 28 is rotated on the vertical plate 26 on a fixed axis. The ratchet rod 25 corresponds to the position of the movable copper plate 28, and the positioning copper plate 27 and the movable copper plate 28 are both electrically connected to the heat dissipation fan and are arranged in series with the heat dissipation fan.

[0074] like Figure 2 , Figure 3 and Figure 7 As shown, when the temperature of the electrical equipment reaches the second threshold value, the horizontal movement process of the base 2 can change the relative positions of the stop block 8 and the swing rod 9 fixed thereon, thereby driving the swing rod 9 to deflect in the vertical direction, wherein the swing rod 9 can drive the swing rod 25 fixedly connected thereto through the transverse column 23 to deflect synchronously.

[0075] Therefore, when the temperature reaches the second threshold value, the lever 25 can drive the movable copper plate 28 on one side to separate from the positioning copper plate 27 when it deflects, so that the circuit where the heat dissipation fan is located is in an open circuit state, wherein the movable copper plate 28 and the positioning copper plate 27 can be fixed by providing micro magnets with opposite magnetic properties on both, so that the two can contact and keep the circuit where the heat dissipation fan is located unobstructed.

[0076] Furthermore, the sensor module includes a current sensor, a voltage sensor, a temperature sensor, a smoke sensor and a flame detector. The cabinet 1 is provided with a processor module for receiving the sensor module signal. The edge computing technology built into the processor module analyzes the received signal and filters out data points with abnormalities or potential fire risks. The processor module is also provided with a machine learning algorithm for evaluating and predicting the fire risk of circuit equipment based on historical data and real-time data.

[0077] The processor module is built with a wireless communication module for remotely transmitting the detection result signal to the terminal module, and the processor module is electrically connected to an audible and visual alarm for early warning.

[0078] The fire protection device integrates a variety of sensors, including one or more of current sensors, voltage sensors, temperature sensors, smoke sensors and flame detectors. These sensors continuously monitor various parameters in the power system and transmit the monitored data to the processor module in the power equipment cabinet in real time. The processor module is equipped with edge computing technology, which can quickly process and analyze the signals received by the sensor module. Through analysis, the processor module can analyze and identify abnormal data or potential fire risk data points based on the received sensor module signals, and effectively screen out risk factors that may cause fires, such as sudden current surges, abnormal voltage or sharp temperature increases.

[0079] In addition, the processor module is also configured with an algorithm based on machine learning, which combines historical data and real-time data to continuously optimize the fire risk assessment and prediction model and improve the accuracy of fire prediction. By learning from historical data and real-time data, this intelligent data processing method enables the fire protection device to not only monitor in real time, but also conduct forward-looking risk analysis and early warning, assess and predict the fire risk of circuit equipment, and significantly improve the safety of power equipment.

[0080] At the same time, the processor module is further integrated with or connected to a wireless communication module, which enables the processor to wirelessly transmit processed and analyzed data or alarm signals (collectively referred to as detection result signals) to a remote terminal module. This function allows the remote monitoring center to receive alarms and status data of power equipment in real time, allowing managers to respond quickly and take necessary safety measures.

[0081] When the processor module identifies a high-risk alarm, in addition to sending a signal through the wireless communication module, it will also activate the connected sound and light alarm, which will provide direct warning of the emergency situation to on-site personnel by emitting a loud alarm and obvious flashing lights. This immediate physical alarm mechanism further increases the practicality of the equipment in fire prevention and response.

[0082] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
