[0002] A fire-fighting power cut-off device refers to a device that can control and cut off all currents except for fire-fighting electrical appliances during a fire, so as to ensure that electrical equipment will not leak electricity during a fire due to current.

[0003] However, since the existing fire-fighting power cut-off devices need to uniformly control multiple electrical circuits, which leads to the concentration of multiple electronic components, ventilation openings need to be provided on both sides of the power distribution cabinet for heat dissipation. However, the ventilation openings also need to be blocked to prevent rainwater from entering. If the blocking is increased, the heat dissipation effect will become worse, resulting in the inability to meet the heat dissipation requirements in various weather conditions. Summary of the Utility Model

[0004] The purpose of the utility model is to provide a fire-fighting power cut-off module, which solves the problem that because a fire-fighting power cut-off device is arranged in a power distribution cabinet through multiple electronic components, the internal heat generation is too high and then damaged, which will cause the failure of emergency measures and thus increase potential safety hazards.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0021] In the description of the present utility model, it should also be noted that unless otherwise clearly defined and limited, if the terms "arranged", "installed", "connected", and "connected" are used, they should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected or indirectly connected through an intermediate medium, and it can be the internal communication of two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0022] The following Figures 1 to 4 will be used to describe the present utility model in detail.

[0023] A fire cut-off module includes a distribution box 1. An integrated circuit 102 is connected inside the distribution box 1. Above the integrated circuit 102 is a fire cut-off device 101. On both sides of the distribution box 1 are ventilation openings 2. In the middle of the ventilation openings 2 is a filter screen 203. On both sides of the opening of the ventilation openings 2 are side plates 201. In the middle of the side plates 201 is a baffle 202. The baffle 202 swings along the axis. On the opposite side of the side plates 201 is a limiting component. The limiting component is displaced along the groove under pressure. The integrated circuits 102 are set up by combining several of them. Several integrated circuits 102 are connected to the fire cut-off device 101 through terminal relays uniformly.

[0024] First, combine several integrated circuits 102 together, and then linearly connect them to the fire cut-off device 101 uniformly, so that the fire cut-off device 101 can timely control the integrated circuit 102 to cut off the circuit. At the same time, because several integrated circuits 102 are combined together, the integrated circuits 102 can be produced uniformly, making it more convenient to use without the need to produce and install each one separately.

[0025] Furthermore, the baffle 202 also includes a hinge shaft 2021. The hinge shaft 2021 is connected to one end of the baffle 202. The baffle 202 is connected between the tops of two side plates 201 through the hinge shaft 2021 at one end. The limiting component includes a limiting block 2011, an extrusion inclined surface 2012, and a contraction groove 2013. The contraction groove 2013 is arranged on the opposite side of the side plate 201. The limiting block 2011 is arranged in the middle of the contraction groove 2013. The extrusion inclined surface 2012 is arranged at one end of the limiting block 2011. The limiting block 2011 is arranged on the side of the side plate 201 close to the top. One side of the limiting block 2011 is connected to the contraction groove 2013 through several springs. The extrusion inclined surface 2012 is arranged at one end of the limiting block 2011 close to the baffle 202.

[0026] At the same time, when the fire cut-off device 101 and the integrated circuit 102 are installed in the distribution box 1, ventilation is carried out through the ventilation openings 2 on both sides to prevent the temperature in the distribution box 1 from being too high, which may cause damage to electronic components due to excessive temperature in the distribution box 1.

[0027] And a filter screen 203 is also arranged in the middle of the ventilation openings 2 to prevent some particles and impurities from entering the distribution box 1. Then, side plates 201 are arranged on both sides of the opening of the ventilation openings 2. The baffle 202 is hinged to the side plates 201 through the side plates 201. Then, the bottom of the baffle 202 will abut against the limiting block 2011 on the opposite side of the side plates 201. Since the limiting block 2011 is connected to the contraction groove 2013 through a spring, the baffle 202 will abut against the limiting block 2011 and cannot deflect by itself, so that the baffle 202 will maintain a certain inclination angle and will not block the ventilation openings 2.

[0028] When it is rainy and it is necessary to block the ventilation opening 2 at a certain angle, the baffle 202 can be pressed with a certain force, causing it to deflect along the hinge axis 2021, thereby increasing the blocking angle of the ventilation opening 2. At the same time, when the baffle 202 deflects, it will squeeze the inclined surface 2012 at one end of the limiting block 2011 to move, thus applying a certain force to the limiting block 2011, causing it to retract into the contraction groove 2013 through the compression of the spring. Then, through the reset clamping of the spring of the limiting block 2011, a certain force clamping will be applied to both sides of the baffle 202, so that its deflection angle will be clamped and fixed when there is no pressing force, enabling it to flexibly adjust the deflection angle of the baffle 202 to change the range and angle of the baffle 202 blocking the ventilation opening 2 according to the rainfall. At the same time, it can also drain the rainwater flowing down without flowing into the ventilation opening 2.

[0029] The following is the specific implementation process of the present utility model. First, several integrated circuits 102 are combined and set together, and then they are linearly connected to the fire cut-off device 101 in a unified manner, so that the fire cut-off device 101 can timely control the integrated circuit 102 to turn off the circuit. At the same time, because several integrated circuits 102 are combined together, the integrated circuit 102 can be produced in a unified manner, making its use more convenient. There is no need to produce and install each one separately. When the fire cut-off device 101 and the integrated circuit 102 are installed in the distribution box 1, ventilation is carried out through the ventilation openings 2 on both sides to prevent the temperature in the distribution box 1 from being too high, which may cause damage to the electronic components due to excessive temperature. A filter screen 203 is also provided in the middle of the ventilation opening 2 to prevent some particles and impurities from entering the distribution box 1. Then, side plates 201 are provided on both sides of the opening of the ventilation opening 2. The baffle 202 is hinged to the side plates 201. The bottom of the baffle 202 will abut against the limit block 2011 on the opposite side of the side plate 201. Since the limit block 2011 is connected to the contraction groove 2013 by a spring, the baffle 202 will abut against the limit block 2011 and cannot deflect on its own, so that the baffle 202 will maintain a certain inclination angle and will not block the ventilation opening 2. If it is rainy and the ventilation opening 2 needs to be blocked at a certain angle, a certain force can be applied to press the baffle 202, so that it will deflect along the hinge axis 2021 to increase the blocking angle of the ventilation opening 2. At the same time, when the baffle 202 deflects, it will squeeze the extrusion inclined surface 2012 at one end of the limit block 2011 to move, thereby applying a certain force to the limit block 2011, so that it will retract into the contraction groove 2013 through the compression of the spring. Then, through the reset clamping of the spring of the limit block 2011, a certain force clamping will be applied to both sides of the baffle 202, so that it will be clamped and fixed at the deflection angle without force pressing, enabling it to flexibly adjust the deflection angle of the baffle 202 to change the range and angle of the baffle 202 blocking the ventilation opening 2 according to the rainfall, and at the same time, it can also drain the rainwater flowing down without flowing into the ventilation opening 2.

[0030] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, various changes and modifications can be made to the present utility model. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
