Detailed Implementation

[0024] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0025] The purpose of this invention is to provide an outdoor cable branch box with fire extinguishing function.

[0026] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the present invention will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0027] Example 1

[0028] refer to Figures 1-3As shown, the outdoor cable branch box 100 provided in this embodiment includes: a box body 1; a fire extinguishing assembly disposed at the top of the box body 1, a fire detection device for detecting fire, an opening mechanism for controlling the opening of the cover, a control element, and a power supply. The fire extinguishing assembly includes a powder box 2, a cover, a screen 4, and a first driving device. The powder box 2 is used to contain fire extinguishing powder 5, such as dry powder fire extinguishing agent. A discharge port is provided at the bottom of the powder box 2, and the cover is disposed at the bottom of the powder box 2 to open and close the discharge port. The screen 4 is disposed inside the powder box 2 and is disposed opposite to the discharge port. The fire extinguishing powder 5 is disposed above the screen 4. The screen 4 is slidably connected to the two side walls opposite to the box body 1. The first driving device is used to drive the screen 4 to slide back and forth. The length of the screen 4 should be as long as possible, and the specific length is determined according to actual needs, so as to avoid the screen 4 from detaching from the side walls during the sliding process. The fire detection device is installed inside the enclosure 1. The opening mechanism, the fire detection device, and the first drive device are all communicatively connected to the control element. The control element controls the opening mechanism and the first drive device based on the detection results of the fire detection device. The power supply is connected to the first drive device, the fire detection device, the opening mechanism, and the control element to supply power to them.

[0029] A fire in an outdoor cable distribution box 100 typically originates from an internal electrical component. This component is located inside the box 1, below the fire extinguishing assembly. In operation, when the fire detection device detects a fire inside the box 1, the opening mechanism activates, opening the cover and thus the discharge port. Simultaneously, the first drive device operates, controlling the screen 4 to slide back and forth. As the screen 4 slides, the extinguishing powder 5 passes through the mesh of the screen 4 and the discharge port, falling into the box 1 to extinguish the fire. The outdoor cable distribution box 100 provided by this invention has a fire extinguishing function, preventing the spread of fire and reducing economic and property losses.

[0030] In this embodiment, the fire detection device is specifically a smoke sensor used to detect the smoke inside the enclosure 1. Of course, the fire detection device can also be other devices capable of detecting fires; this is just an example.

[0031] In this embodiment, two sliding grooves are provided on the two opposite side walls of the box body 1, which respectively match the shape of the two ends of the screen 4, and the two ends of the screen 4 are slidably disposed in the two sliding grooves.

[0032] In this embodiment, as Figures 1-2As shown, the cover plate is composed of a first plate 12 and a second plate 13. When the cover plate is in the closed state, one end of the first plate 12 and one end of the second plate 13 are positioned opposite each other and fit together. The other ends of the first plate 12 and the second plate 13 are rotatably connected to the side wall of the box 1.

[0033] In this embodiment, the opening mechanism is an electromagnet 14. The first plate 12 and the second plate 13 are equipped with iron plates for the electromagnet 14 to attract. The electromagnet 14 is located on the inner wall of the housing 1. When energized, the electromagnet 14 attracts the iron plates, and the cover is closed. Due to the obstruction of the cover, the extinguishing powder 5 cannot enter the housing 1. When de-energized, the electromagnet 14 loses its attraction function. Under the influence of gravity, the first plate 12 and the second plate 13 rotate, the cover opens, and the extinguishing powder 5 can enter the housing 1.

[0034] In this embodiment, as Figure 3 As shown, the first driving device includes a first motor 6, and also includes a turntable 7, a connecting column 8, and a connecting plate 9. The turntable 7 is sleeved on the output shaft of the first motor 6, and the axial direction of the turntable 7 coincides with the axis of the output shaft of the first motor 6. The turntable 7 is connected to the first motor 6 in a transmission manner. The connecting column 8 is disposed on the turntable 7, and the axis of the connecting column 8 is parallel to the axis of the turntable 7. The connecting column 8 is eccentrically disposed. The connecting plate 9 is connected to the screen 4, and the connecting plate 9 is provided with a guide groove 901 perpendicular to the screen 4. The connecting column 8 is slidably disposed in the guide groove 901.

[0035] In actual use, the first motor 6 rotates, driving the turntable 7 to rotate synchronously. While the turntable 7 rotates, the connecting column 8 slides in the guide groove 901. At the same time, driven by the connecting column 8, the screen 4 begins to slide. By controlling the forward and reverse rotation of the first motor 6 and the rotation angle of the first motor 6, the screen 4 can be made to slide back and forth as required (depending on the actual situation).

[0036] In this embodiment, as Figures 1-2 As shown, the outdoor cable branch box 100 also includes a photovoltaic power generation panel 3 and a second drive device. The power source is a storage battery. One end of the photovoltaic power generation panel 3 is rotatably connected to the top of the box body 1. The second drive device is connected to the photovoltaic power generation panel 3 to drive the photovoltaic power generation panel 3 to rotate. The photovoltaic power generation panel 3 is connected to the storage battery to store the electrical energy generated by the photovoltaic power generation panel 3 into the storage battery.

[0037] Furthermore, such as Figures 1-2As shown, the second drive device includes a second motor 15, a second crank 16, and a second connecting rod 17. One end of the second crank 16 is sleeved on the output shaft of the second motor 15 and is connected to the output shaft of the second motor 15 for transmission. The other end of the second crank 16 is rotatably connected to one end of the second connecting rod 17, and the other end of the second connecting rod 17 is rotatably connected to the photovoltaic power generation panel 3.

[0038] In practical use, the second motor 15 drives the second connecting rod 17 to rotate via the second crank 16, and then drives the photovoltaic panel 3 to rotate via the second connecting rod 17, thus changing the angle of the photovoltaic panel 3. By making the angle of the photovoltaic panel 3 adjustable, more solar energy can be obtained.

[0039] In this embodiment, as Figures 1-2 As shown, in order to avoid the internal temperature of the enclosure 1 from getting too high, a heat dissipation structure 18 is provided on one side of the enclosure 1 to dissipate the heat inside the enclosure 1.

[0040] Furthermore, the heat dissipation structure 18 is a louver.

[0041] Furthermore, the heat dissipation structure 18 preferably has louvers with adjustable blade angles.

[0042] In this embodiment, the outdoor cable branch box 100 also includes an alarm, which is communicatively connected to the control element. Specifically, the alarm can be a buzzer alarm.

[0043] In practical use, when the fire detection device detects a fire inside the enclosure 1, the control element can activate the alarm to alert people to take action.

[0044] In this embodiment, the control element is specifically a PLC controller. The electromagnet 14 is electrically connected to the power supply via an electromagnetic relay. The smoke sensor, the electromagnetic relay, and the first motor 6 are all communicatively connected to the PLC controller. Of course, the control element is not limited to a PLC controller; it can also be other elements, such as a control circuit board. Furthermore, it should be noted that the program running on the PLC controller and the specific circuitry of the control circuit board are existing technologies and are not the focus of this invention; therefore, they will not be elaborated upon here.

[0045] Example 2

[0046] The difference between this embodiment and Embodiment 1 is that, Figure 4 As shown, the outdoor cable branch box 100 provided in this embodiment includes: a first motor 6, and also includes: a first crank 10 and a first connecting rod 11. One end of the first crank 10 is sleeved on the output shaft of the first motor 6 and is connected to the output shaft of the first motor 6 for transmission. The other end of the first crank 10 is rotatably connected to one end of the first connecting rod 11, and the other end of the first connecting rod 11 is rotatably connected to the screen 4.

[0047] In actual use, the first motor 6 drives the first connecting rod 11 to rotate through the first crank 10, and then drives the screen 4 to slide back and forth through the first connecting rod 11.

[0048] This specification uses specific examples to illustrate the principles and implementation methods of the present invention. The descriptions of the above embodiments are only for the purpose of helping to understand the method and core ideas of the present invention. Furthermore, those skilled in the art will recognize that, based on the ideas of the present invention, there will be changes in the specific implementation methods and application scope. Therefore, the content of this specification should not be construed as a limitation of the present invention.
