Description

Technical Field

[0001] This invention relates to the field of distribution box technology, and in particular to a safety power distribution box with fire protection function. Background Technology

[0002] Distribution boxes can rationally distribute electrical energy to various branch circuits or electrical equipment to meet the power needs of different devices. Therefore, distribution boxes need to have a high level of safety protection. In related technologies, when an overload, short circuit, or leakage fault occurs in the circuit of the distribution box, the protective device will automatically cut off the circuit to prevent the fault from spreading, thereby ensuring the safety of the distribution box. However, if a fire occurs in the circuit of the distribution box due to leakage or short circuit, the staff often cannot detect it, so they cannot take timely fire-fighting measures, which can easily lead to a large number of components inside the distribution box being burned. Summary of the Invention

[0003] The present invention aims to at least partially solve one of the technical problems in the related art.

[0004] Therefore, embodiments of the present invention propose a safety power distribution box with fire-fighting function. This safety power distribution box with fire-fighting function can monitor the fire situation inside the distribution box and take timely fire-fighting measures when a fire occurs inside the distribution box, thereby effectively avoiding the risk of the components inside the distribution box being burned.

[0005] According to an embodiment of the present invention, a safety power distribution box with fire protection function includes a box body, a box cover, a controller, a fire detector, and a fire extinguishing assembly. The box body has a receiving cavity, and the box cover is movably connected to the box body and adapted to close the receiving cavity. The controller, the fire detector, and the fire extinguishing assembly are all installed in the receiving cavity. The fire detector is used to monitor the fire situation in the receiving cavity, and the fire extinguishing assembly is adapted to extinguish the fire in the receiving cavity. The fire detector and the fire extinguishing assembly are both electrically connected to the controller so that the controller controls the operation of the fire extinguishing assembly based on the data information fed back by the fire detector.

[0006] According to an embodiment of the present invention, a safety power distribution box with fire-fighting function is formed by a box body and a box cover, wherein the accommodating cavity of the box body is used to house various components, and a controller, a fire detector, and a fire extinguishing assembly are installed in the accommodating cavity. The three components work together to achieve timely control of the fire situation inside the distribution box. That is, the fire detector monitors the fire situation inside the accommodating cavity in real time and feeds back the detected data information to the controller, so that the controller controls the operation of the fire extinguishing assembly according to the data information to extinguish the fire in the accommodating cavity in time. Therefore, compared with related technologies, the present invention can monitor the fire situation inside the distribution box and take timely fire extinguishing measures when a fire occurs inside the distribution box, thereby effectively avoiding the risk of the components inside the distribution box being burned.

[0007] In some embodiments, the safety power distribution box further includes an alarm connected to the box body, with at least a portion of the alarm located outside the box body, and the alarm being electrically connected to the controller and used for early warning and alerting.

[0010] In some embodiments, the fire extinguishing assembly includes a high-pressure dry powder box and a nozzle.

[0011] The high-pressure dry powder box is installed in the accommodating cavity and has a powder storage cavity. The powder storage cavity is used to hold fire extinguishing dry powder. The high-pressure dry powder box is provided with a spray outlet that communicates with the powder storage cavity. A control valve is installed in the spray outlet. The control valve is electrically connected to the controller so that the control valve can control the opening and closing of the spray outlet.

[0012] The nozzle is connected to the outlet and is adapted to spray fire extinguishing dry powder onto the ignition point of the accommodating cavity.

[0013] In some embodiments, there are multiple spray outlets arranged in an array on the high-pressure dry powder box, and there are multiple nozzles that correspond one-to-one with each spray outlet.

[0014] In some embodiments, the lid has a first end and a second end arranged opposite to each other, the first end of the lid is pivotally connected to the box body, the pivot axis of the lid is aligned with the height direction of the box body, and the second end of the lid is adapted to press against the box body to close the accommodating cavity.

[0015] In some embodiments, the enclosure includes a top plate, a bottom plate, two side plates, and a back plate.

[0016] The top plate and the bottom plate are arranged at intervals along the height direction of the box body, and the two side plates are arranged at intervals along a first direction, which is perpendicular to the height direction of the box body. The two side plates are connected between the top plate and the bottom plate and the four together form a frame. Either of the two side plates is pivotally connected to the first end of the box cover.

[0017] The back panel and the lid are respectively located on both sides of the frame along the second direction, which is perpendicular to the first direction and the height direction of the box. The back panel is connected to the frame and together defines the accommodating cavity.

[0018] In some embodiments, either of the two side plates is provided with a wire passage hole that connects the accommodating cavity to the outside, so that the wire harness can enter and exit the accommodating cavity.

[0019] In some embodiments, a rubber sleeve is detachably fitted into the wire hole, and the rubber sleeve is fitted onto the wire harness.

[0020] In some embodiments, the safety power distribution box further includes a mounting plate and a locking member. The mounting plate is connected to either the frame or the back plate and has a mounting hole. At least a portion of the locking member is adapted to pass through the mounting hole and connect to a load-bearing object to lock the box body onto the load-bearing object.

[0021] In some embodiments, there are multiple mounting plates arranged at circumferential intervals along the frame, and there are multiple locking members corresponding to each mounting plate.

[0022] Furthermore, the locking element is one of bolts, screws, and screws.

Detailed Implementation

[0028] Embodiments of the present invention are described in detail below, examples of which are illustrated in the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain the present invention, and should not be construed as limiting the present invention.

[0029] like Figure 1 and Figure 2 As shown in the figure, a safety power distribution box with fire protection function according to an embodiment of the present invention includes a box body 1, a box cover 2, a controller 3, a fire detector 4, and a fire extinguishing assembly 5. The box body 1 has a receiving cavity 11, and the box cover 2 is movably connected to the box body 1 and is suitable for closing the receiving cavity 11. The controller 3, the fire detector 4, and the fire extinguishing assembly 5 are all installed in the receiving cavity 11. The fire detector 4 is used to monitor the fire situation in the receiving cavity 11, and the fire extinguishing assembly 5 is suitable for extinguishing the fire in the receiving cavity 11. The fire detector 4 and the fire extinguishing assembly 5 are both electrically connected to the controller 3 so that the controller 3 can control the operation of the fire extinguishing assembly 5 according to the data information fed back by the fire detector 4.

[0030] It is understood that the safety power distribution box with fire-fighting function according to the embodiments of the present invention has a shell structure formed by a box body 1 and a box cover 2. The accommodating cavity 11 of the box body 1 is used to house various components. At the same time, a controller 3, a fire detector 4, and a fire extinguishing component 5 are installed in the accommodating cavity 11. The fire situation inside the distribution box can be controlled in a timely manner through the cooperation of the three. That is, the fire detector 4 monitors the fire situation inside the accommodating cavity 11 in real time and feeds back the detected data information to the controller 3. The controller 3 controls the operation of the fire extinguishing component 5 according to the data information to extinguish the fire in the accommodating cavity 11 in a timely manner. Therefore, compared with related technologies, the present invention can monitor the fire situation inside the distribution box and take timely fire extinguishing measures when a fire occurs inside the distribution box, thereby effectively avoiding the risk of the components inside the distribution box being burned.

[0031] like Figure 1 and Figure 2As shown, in some embodiments, the safety power distribution box further includes an alarm 6, which is connected to the box body 1, and at least a portion of the alarm 6 is located outside the box body 1, that is, at least a portion of the alarm 6 protrudes from the outer peripheral wall of the box body 1, to ensure that personnel can observe the warning signal of the alarm 6. The alarm 6 is electrically connected to the controller 3 and is used for warning and reminder purposes.

[0032] Understandably, the addition of alarm 6 enhances the functionality of the safety power distribution box, enabling it to promptly alert staff in the event of a fire, further reducing the risk of damage to components inside the box and ensuring its operational performance.

[0033] Furthermore, the alarm 6 may not be limited to an audible and visual alarm 6.

[0034] like Figure 1 and Figure 2 As shown, in some embodiments, the fire detector 4 is used to monitor at least one parameter information among temperature, smoke, gas and infrared radiation in the accommodating cavity 11. That is, the fire detector 4 may include at least one of a temperature detector, a smoke detector, a special gas detector and an infrared beam detector.

[0035] The preferred fire detector 4 is used to monitor each parameter information in the accommodating cavity 11, including temperature, smoke, gas, and infrared radiation, to comprehensively analyze and determine whether a fire has occurred, ensuring the accuracy and reliability of fire monitoring and further enhancing the monitoring capabilities for fires.

[0036] like Figure 1 and Figure 2 As shown, in some embodiments, the fire extinguishing component 5 includes a high-pressure dry powder box 51 and a nozzle 52.

[0037] The high-pressure dry powder box 51 is installed in the accommodating cavity 11 and has a powder storage cavity for holding fire extinguishing dry powder. The high-pressure dry powder box 51 is provided with a spray outlet that communicates with the powder storage cavity. A control valve 53 is installed at the spray outlet. The control valve 53 is electrically connected to the controller 3 so that the opening and closing of the spray outlet can be controlled by the control valve 53.

[0038] The nozzle 52 is connected to the outlet and is suitable for spraying fire extinguishing dry powder onto the ignition point of the accommodating cavity 11.

[0039] It is understandable that by opening and closing the control valve 53 through the controller 3, when the control valve 53 is opened, the powder storage chamber, the spray outlet and the nozzle 52 are connected, so that the nozzle 52 can extinguish the fire point in the accommodating chamber 11. When the control valve 53 is closed, the spray outlet is cut off, so as to realize automatic fire extinguishing of the fire point in the accommodating chamber 11.

[0040] It should be noted that the specific connection structure and control principle between the controller 3, fire detector 4, alarm 6, and control valve 53 can adopt existing technologies in the field, and will not be elaborated here. Furthermore, the specific structure and working principle of the sprinkler head 52 can also adopt existing technologies in the field.

[0041] like Figure 1 As shown, in some embodiments, there are multiple nozzles arranged in an array on the high-pressure dry powder box 51, and multiple nozzles 52 corresponding to the nozzles one by one, so as to increase the dry powder spray coverage of the accommodating cavity 11 and ensure good fire extinguishing effect.

[0042] like Figure 1 As shown, in some embodiments, the lid 2 has a first end 21 and a second end 22 arranged opposite to each other. The first end 21 of the lid 2 is pivotally connected to the box body 1. The pivot axis of the lid 2 is in the same direction as the height direction of the box body 1. The second end 22 of the lid 2 is adapted to press against the box body 1 to close the accommodating cavity 11.

[0043] It is understandable that hinged connection between the cover 2 and the body 1 allows for easy opening and closing of the accommodating cavity 11, which is beneficial for the maintenance and disassembly of the safety power distribution box. The structure is simple and easy to operate.

[0044] Specifically, the first end 21 of the lid 2 may be hinged to the box body 1 via a hinge or hinge shaft (the extension direction of the hinge shaft is consistent with the height direction of the box body 1) to realize the pivoting of the lid 2 relative to the box body 1.

[0045] like Figure 1 As shown, in some embodiments, the housing 1 includes a top plate 12, a bottom plate 13, two side plates 14 and a back plate 15.

[0046] The top plate 12 and the bottom plate 13 are arranged at intervals along the height direction of the box 1, and the two side plates 14 are arranged at intervals along the first direction, which is perpendicular to the height direction of the box 1. The two side plates 14 are connected between the top plate 12 and the bottom plate 13 and the four together form a frame. Either of the two side plates 14 can be pivotally connected to the first end 21 of the box cover 2.

[0047] The back panel 15 and the lid 2 are respectively located on both sides of the frame along the second direction. The second direction is perpendicular to the first direction and the height direction of the box 1. The back panel 15 is connected to the frame and together defines the accommodating cavity 11.

[0048] It is understandable that the housing 1 adopts a hollow cuboid structure consisting of a top plate 12, a bottom plate 13, two side plates 14 and a back plate 15, which is convenient for production and processing, has a low manufacturing cost, and is conducive to the layout and installation of various components in the accommodating cavity 11, and the overall structure is simple.

[0049] Specifically, the first direction can be the front-to-back direction shown in the figure. The height direction of the housing 1 can be the up-down direction shown in the figure. The second direction can be the left-to-right direction shown in the figure. Taking the figure as an example, the top plate 12 is located above the bottom plate 13, the two side plates 14 are respectively located at the front and rear ends of the bottom plate 13, the back plate 15 is located at the left end of the bottom plate 13, and the lid 2 is located at the right end of the bottom plate 13. The first end 21 of the lid 2 can be pivotally connected to the edge of the side plate 14 at the rear end of the bottom plate 13. The controller 3 and the fire detector 4 can be installed on the top plate 12, and the alarm 6 can also be installed on the top plate 12, with at least a portion of the alarm 6 protruding from the outside of the top plate 12. The high-pressure dry powder box 51 can be installed on the side plate 14. The top plate 12, the bottom plate 13, the two side plates 14, and the back plate 15 can be integrally formed.

[0050] like Figure 1 As shown, in some embodiments, either of the two side plates 14 is provided with a wire passage hole 141 that connects the receiving cavity 11 to the outside, so that the wire harness can enter and exit the receiving cavity 11.

[0051] In some embodiments, a rubber sleeve (not shown in the figure) is detachably fitted into the wire hole 141. The rubber sleeve is fitted onto the wire harness to seal the wire hole 141, reducing the risk that external dust and other objects can easily enter the receiving cavity 11 through the wire hole 141, and to a certain extent preventing dust and other objects from corroding and damaging the components in the receiving cavity 11.

[0052] like Figure 1 As shown, in some embodiments, the safety power distribution box further includes a mounting plate 7 and a locking member (not shown in the figure). The mounting plate 7 is connected to either the frame or the back plate 15 and is provided with a mounting hole 71. At least a portion of the locking member is adapted to pass through the mounting hole 71 and connect to a load-bearing object to lock the box 1 onto the load-bearing object, which is the foundation used to support the safety power distribution box at the installation site, such as a wall.

[0053] Understandably, the mounting plate 7 increases the contact area between the safety power distribution box and the load-bearing object, ensuring reliable and convenient fixing of the safety power distribution box.

[0054] Specifically, the mounting plate 7 can be integrally formed on the edge of the side plate 14 and flush with the back plate 15. That is, the mounting plate 7 can be located on the front side of the side plate 14 at the front end of the base plate 13, or the mounting plate 7 can be located on the rear side of the side plate 14 at the rear end of the base plate 13.

[0055] like Figure 1 As shown, there are multiple mounting plates 7 arranged at circumferential intervals along the frame, and multiple locking elements corresponding to the mounting plates 7 one by one, to further ensure the reliable installation of the safety power distribution box.

[0056] Furthermore, the locking element is one of bolts, screws, and screws (not shown in the figure).

[0057] like Figure 1 As shown, in some embodiments, the safety power distribution box further includes a safety switch 8. The safety switch 8 is pivotally connected to the box cover 2 and has a first position and a second position. The safety switch 8 is located between the receiving cavity 11 and the box cover 2. The receiving cavity 11 is provided with a slot (not shown in the figure). The safety switch 8 is spaced apart from the slot in the first position. When the box cover 2 closes the receiving cavity 11, the safety switch 8 is located in the second position and is engaged in the slot. The slot limits the safety switch 8 in the left and right directions to lock the box cover 2 onto the box body 1.

[0058] It is understandable that by embedding the safety switch 8 between the accommodating cavity 11 and the cover 2, the corrosion and damage of the safety switch 8 by the external environment can be reduced, ensuring that the cover 2 is reliably locked on the box body 1, while extending the service life of the safety switch 8. Furthermore, by rotating the safety switch 8 (e.g., by using a key), the safety switch 8 can be moved away from or closer to the slot, thereby facilitating the opening or locking of the cover 2.

[0059] Specifically, the safety switch 8 can be connected to the cover 2 via a rotating shaft. At least part of the rotating shaft can be located outside the cover 2, and a socket can be formed coaxially in the rotating shaft. The socket extends to the end face of the rotating shaft that protrudes outside the cover 2. The rotating shaft can be driven to rotate by inserting a key into the socket, thereby causing the safety switch 8 to pivot relative to the cover 2.
