Description

Technical Field

[0001] The present invention relates to the technical field of emergency power supply devices, and in particular to an emergency power supply device for a communication base station. Background Art

[0002] Emergency power supply can be used for power supply of base station grid. It is mainly composed of input and output unit, charging module, battery pack, inverter, monitor, output switching device and other parts. The existing emergency power supply for base station power supply is usually placed in an external power box. The energy storage of emergency power supply is divided into solar charging and power line charging. For the construction environment of communication base station, solar charging is generally used to charge the batteries in the emergency power supply equipment.

[0003] To prevent the internal temperature of the power box from being too high, heat dissipation vents need to be opened on the surface of the power box. However, since the communication base station is built in an open area outdoors, the emergency power supply equipment must also be built nearby. Therefore, on rainy days, the traditional heat dissipation vents opened on the surface of the power box are easy to enter rainwater, which will cause the electrical components inside the power box to short-circuit and reduce the service life of the emergency power supply device. In addition, the existing solar charging method usually installs the solar panels in a fixed manner, which is easily affected by the outdoor environment and its service life. Summary of the invention

[0004] In view of the shortcomings of the prior art, the purpose of the present invention is to provide an emergency power supply device for a communication base station to solve the problems raised in the above-mentioned background technology. The present invention has a novel structure. A rain cover is arranged on the top of the cabinet to ensure its rainproof and waterproof effects while providing a certain heat dissipation capacity. The driving component can unfold the solar panels on the inclined surface of the rain cover to store electrical energy for the internal emergency power supply equipment. One end of the dustproof net at the bottom of the rain cover can enhance the heat dissipation capacity inside the cabinet, and the dustproof net can be cleaned in time to prevent dust from clogging and affecting the heat dissipation performance.

[0005] In order to achieve the above-mentioned purpose, the present invention is implemented through the following technical scheme: an emergency power supply device for a communication base station, including a cabinet, emergency power supply electrical components are installed inside the cabinet, and the emergency power supply electrical components inside the cabinet include input and output units, charging modules, battery packs, inverters, monitors, and output switching devices. A cabinet door is installed at the front end of the cabinet, and a rain cover is fixed on the top of the cabinet, and the front and rear sides of the rain cover are inclined. A mounting plate is embedded in the front and rear inclined surfaces of the rain cover, and a solar panel is installed on the inner surface of the mounting plate. The top of the cabinet penetrates into the rain cover. An air duct is provided at the bottom, and a heat dissipation fan connected to the air duct is installed in the cabinet, the rain cover is provided with a dustproof net at the other end of the air duct, and the dustproof net is flush with the bottom surface of the rain cover, driving components are provided on both outer sides of the rain cover, and the driving component includes a connecting frame, connecting shafts are rotatably installed on the top of both ends of the connecting frame through bearings, ear plates are fixed on both sides of the outer wall of the mounting plate, and the other end of the connecting shaft is fixed on the ear plates, two groups of sweeping plates are symmetrically provided on the bottom surface of the rain cover, and a connecting rope is fixed on the top of the sweeping plate, the connecting rope passes through both sides of the top of the rain cover, and the connecting frame drives the connecting rope to move up and down.

[0006] Furthermore, ventilation ducts communicating with the interior of the cabinet are fixed on both sides of the cabinet, and air outlets are provided at the bottom of the ventilation ducts.

[0007] Furthermore, the driving assembly also includes an electric push rod, and the electric push rod is fixed on the outer wall of the rain cover on both sides of the connecting frame, and the extended end of the electric push rod is fixedly connected to the side of the connecting frame.

[0008] Furthermore, motors are fixed on the top of both sides of the rain cover, and a horizontal plate is fixed on the outside of the motor of the rain cover. The output end of the motor rotates to pass through the horizontal plate, and drive shafts are rotatably installed on both ends of the horizontal plate through bearings. A transmission belt is installed between the rear end of the drive shaft and the output end of the motor, and the two groups of the transmission belts are staggered.

[0009] Furthermore, a plug plate is fixed to the other end of the driving shaft, a slot is provided at one end of the connecting shaft away from the ear plate, and the plug plate can be slidably inserted into the slot.

[0010] Furthermore, the bottom of the connecting frame is squeezed and contacted with a support plate, and the top of the support plate is fixedly connected to the other end of the connecting rope. A moving groove is opened on the outer wall of the rain cover corresponding to the moving path of the support plate, and the support plate slides along the moving groove.

[0011] Furthermore, the inner walls on both sides of the bottom of the rain cover are provided with sliding grooves, and the two ends of the sweeping plate slide along the sliding grooves. Two return springs in opposite directions are fixed in the middle position of the sliding grooves, and the other end of the return spring is fixedly connected to the sweeping plate.

[0012] Furthermore, drainage grooves are provided at both ends of the rain cover beyond the bottom edge of the cabinet, and the sweeping plate can be sealed at the top of the drainage grooves.

[0013] Furthermore, two air inlets are symmetrically opened on the two side surfaces of the rain cover, and a cover is fixed on the outer wall of the rain cover corresponding to the air inlet, the inner side of the air inlet is blocked by a baffle, and the baffle is fixedly connected to the inner surface of the mounting plate.

[0014] Furthermore, the rain cover is provided with sealing strips at the four sides corresponding to the mounting plate, and the sealing strips can be bonded to the four sides of the mounting plate by gluing the hook surface and gluing the rough surface.

[0015] Beneficial effects of the present invention:

[0016] 1. The present invention embeds the sealing strips into the four sides of the rain cover corresponding to the mounting plate. Each time the mounting plate is retracted close to the inclined surface of the rain cover, the mounting plate can be fixed on the rain cover by gluing the hook surface and the rough surface, thereby reducing the entry of dust and sand into the solar panel storage groove on the inner surface of the mounting plate of the rain cover.

[0017] 2. In the present invention, when the connecting frame is located at the lowest end, the bottom squeezes the support plate, and then the support plate pulls the pull rope to move downward, and the sweeping plate moves along the slide groove to the position of the sewage chute to block the sewage chute. In this state, when not in use, the rain cover is sealed to a certain extent to reduce the entry of dust and rainwater to damage the electrical appliance. Similarly, when the connecting frame moves upward, the support plate is not limited by squeezing, and the reset spring drives the sweeping plate to move to the middle position top of the dustproof net. In this state, when the mounting plate is retracted next time, the sweeping plate can clean the dust on the surface of the dustproof net and push it out of the sewage chute to maintain the dustproof net without dust accumulation.

[0018] 3. The present invention drives the connecting frame to rise through the electric push rod, and lifts the mounting plate away from the storage slot position of the rain cover through the fixed connection between the connecting shaft and the ear plate, until the plug plate is plugged into the slot. In this part, first, the plugging position of the driving shaft and the connecting shaft is a position where the mounting plate can rotate after moving, and will not collide with the rain cover. At the same time, the tearing force of the rotation can also separate from the sealing strip. The position of the plug plate corresponds vertically to the position of the slot. When the connecting shaft moves vertically, it is plugged into the driving shaft. The motor drives two sets of staggered transmission belts to transmit kinetic energy to the two driving shafts, and flips the mounting plate through the two driving shafts respectively. Adjusting the flipping angle can make the inner solar panel better receive sunlight.

[0019] 4. The present invention uses the heat dissipation fan inside the seal to allow air to pass through the air inlet, seal and ventilation duct to efficiently dissipate heat for the emergency power supply equipment in the cabinet. Because the outlet of the ventilation duct is facing in the right direction, a cover is provided on the periphery of the air inlet and is blocked by a baffle when not in use. This makes the heat dissipation process more suitable for environments near outdoor communication base stations and also saves the inconvenience of frequent manual adjustments.

[0020] 5. Compared with the prior art, the present invention sets a rain cover on the top of the cabinet to ensure its rainproof and waterproof effects while providing a certain heat dissipation capacity. The driving component can unfold the solar panels on the inclined surface of the rain cover to store electric energy for the internal emergency power supply equipment. One end of the dustproof net at the bottom of the rain cover can enhance the heat dissipation capacity inside the cabinet, and the dustproof net can be cleaned in time to prevent dust from clogging and affecting the heat dissipation performance.

DETAILED DESCRIPTION

[0029] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0030] See also Figures 1 to 7 The present invention provides a technical solution: an emergency power supply device for a communication base station, comprising a cabinet 1, wherein emergency power supply electrical components are installed inside the cabinet 1, and the emergency power supply electrical components inside the cabinet 1 include an input and output unit, a charging module, a battery pack, an inverter, a monitor, and an output switching device. A cabinet door 11 is installed at the front end of the cabinet 1, and a rain cover 2 is fixed on the top of the cabinet 1, and the front and rear sides of the rain cover 2 are inclined, and a mounting plate 23 is embedded in the front and rear inclined surfaces of the rain cover 2, and a solar panel is installed on the inner surface of the mounting plate 23. An air duct is provided inside the rain cover 2 at the top of the cabinet 1, and a heat dissipation fan connected to the air duct is installed in the cabinet 1, and a dustproof net 14 is installed at the other end of the rain cover 2 located at the air duct, and the dustproof net 14 is flush with the bottom surface of the rain cover 2, and a driving component 3 is provided on both outer sides of the rain cover 2, and The driving component 3 includes a connecting frame 32, and a connecting shaft 33 is rotatably installed on the top of both ends of the connecting frame 32 through bearings. Ear plates 34 are fixed on both sides of the outer wall of the mounting plate 23, and the other end of the connecting shaft 33 is fixed on the ear plate 34. Two groups of sweeping plates 25 are symmetrically arranged on the bottom surface of the rain cover 2, and a connecting rope 41 is fixed on the top of the sweeping plate 25. The connecting rope 41 passes through both sides of the top of the rain cover 2, and the connecting frame 32 drives the connecting rope 41 to move up and down. When the device is used, the connection principle between the emergency power supply equipment and the communication base station in this device is the existing technology. The emergency power supply equipment is normally cooled by the ventilation duct 12 alone. When the emergency power supply equipment is enabled to supply power to the communication base station or charge and store energy, more heat will be dissipated, and the heat will be efficiently dissipated through the heat dissipation fan. The solar panel can be unfolded through the driving component 3 to charge the internal battery of the emergency power supply equipment.

[0031] In this embodiment, ventilation ducts 12 connected to the inside of the cabinet 1 are fixed on both sides of the cabinet 1, and an air outlet 13 is provided at the bottom of the ventilation duct 12. Two air inlets 21 are symmetrically provided on the two side surfaces of the rain cover 2, and a cover 22 is fixed on the outer wall of the rain cover 2 corresponding to the air inlet 21. The inner side of the air inlet 21 is blocked by a baffle 27, and the baffle 27 is fixedly connected to the inner surface of the mounting plate 23. When the emergency power supply equipment in the cabinet 1 is working or charging and storing energy, a large amount of heat will be dissipated, and a single ventilation channel is not enough to quickly dissipate the heat. In order to avoid heat, the mounting plate 23 is opened by driving the assembly 3. In this state, the air inlets 21 on both sides of the rain cover 2 are opened. Through the action of the heat dissipation fan inside the seal, the air passes through the air inlet 21, the seal and the ventilation duct 12, and the emergency power supply equipment in the cabinet 1 is efficiently cooled. Because of the outlet direction of the ventilation duct 12, a cover 22 is provided on the periphery of the air inlet 21, which is blocked by the baffle 27 when not in use, so that it can be better applied to the environment near the outdoor communication base station, and at the same time, it can also save the inconvenience of frequent manual adjustment.

[0032] In this embodiment, the driving assembly 3 also includes an electric push rod 31, and the electric push rod 31 is fixed on the outer wall of the rain cover 2 on both sides of the connecting frame 32, and the extended end of the electric push rod 31 is fixedly connected to the side of the connecting frame 32, and the motor 36 is fixed to the top of the two sides of the rain cover 2, and the rain cover 2 is fixed with a cross plate 37 on the outside of the motor 36, and the output end of the motor 36 rotates to pass through the cross plate 37, and the two ends of the cross plate 37 are rotatably installed with a driving shaft 39 through bearings, and a transmission belt 38 is installed between the rear end of the driving shaft 39 and the output end of the motor 36, and the two groups of the transmission belts 38 are staggered. A plug plate 310 is fixed to the other end of the driving shaft 39, and a slot 35 is opened at the end of the connecting shaft 33 away from the ear plate 34, and the plug plate 310 can be slidably inserted into the slot 35, and the electric push rod 31 drives the connecting frame 32 to rise, and through the connecting shaft 33 and the ear plate The fixed connection of the plate 34 lifts the mounting plate 23 away from the storage slot position of the rain cover 2 until the plug plate 310 is plugged into the slot 35. In this part, first, the plug-in position of the drive shaft 39 and the connecting shaft 33 is a position where the mounting plate 23 can rotate after moving, and will not collide with the rain cover 2. At the same time, the tearing force of the rotation can also separate the sealing strip 28. The position of the plug plate 310 corresponds vertically to the position of the slot 35. When the connecting shaft 33 moves vertically, it is plugged into the drive shaft 39, and the motor 36 drives two sets of staggered transmission belts 38 to transmit kinetic energy to the two drive shafts 39, and flips the mounting plate 23 through the two drive shafts 39 respectively. Adjusting the flipping angle can make the inner solar panel better receive sunlight (the process and principle of solar power generation to charge the battery of the emergency power supply equipment can refer to the technical method in patent CN219643635U).

[0033] In this embodiment, the bottom of the connecting frame 32 is squeezed and contacted with a support plate 4, and the top of the support plate 4 is fixedly connected to the other end of the connecting rope 41, and the outer wall of the rain cover 2 is provided with a moving groove 42 corresponding to the moving path of the support plate 4, and the support plate 4 slides along the moving groove 42, and the inner walls on both sides of the bottom of the rain cover 2 are provided with sliding grooves 26, and the two ends of the sweeping plate 25 slide along the sliding grooves 26, and two return springs 29 in opposite directions are fixed at the middle position of the sliding groove 26, and the other end of the return spring 29 is fixedly connected to the sweeping plate 25, and the two ends of the rain cover 2 are provided with drainage grooves 24 beyond the bottom edge of the cabinet 1, and the sweeping plate 25 can be blocked at the top of the drainage groove 24, and the connecting frame When 32 is at the bottom, the bottom squeezes the support plate 4, and then the support plate 4 pulls the pull rope to move downward, and the sweeping plate 25 moves along the slide groove 26 to the position of the sewage trough 24 to cover the sewage trough. In this state, when it is not in use, the rain cover 2 is sealed to a certain extent to reduce the entry of dust and rainwater to damage the electrical appliance. Similarly, when the connecting frame 32 moves upward, the support plate 4 is not limited by squeezing, and the reset spring 29 drives the sweeping plate 25 to move to the top of the middle position of the dustproof net 14. In this state, when the mounting plate 23 is retracted next time, the sweeping plate 25 can clean the dust on the surface of the dustproof net 14 and push it out from the sewage trough 24 to maintain the dustproof net 14 without dust accumulation.

[0034] In this embodiment, the rain cover 2 is provided with sealing strips 28 at the four sides corresponding to the mounting plate 23, and the sealing strips 28 can be bonded to the four sides of the mounting plate 23 by gluing the hook surface and gluing the fur surface. The sealing strips 28 are embedded in the surface of the four sides of the mounting plate 23 corresponding to the rain cover 2. Each time the mounting plate 23 is retracted to the inclined surface close to the rain cover 2, the mounting plate 23 can be fixed on the rain cover 2 by gluing the hook surface and gluing the fur surface, thereby reducing dust and sand from entering the solar panel storage groove of the rain cover 2 located on the inner surface of the mounting plate 23 ( The rain cover 2 is provided with special inclined storage grooves corresponding to the mounting plate 23 and the solar panel, in which the mounting plate 23 and the solar panel can be stored to protect the solar panel, while maintaining a flush effect and cooperating with the sealing strip 28 to reduce rainwater infiltration) There are barriers on both sides of the rain cover 2, and the position of the barriers is not fully shown in the figure, that is, there is a cavity inside the rain cover 2, and the mounting plate 23 and the solar panel are stored on the surface of the inclined surfaces on both sides of the rain cover 2 (the inclined surfaces have a certain thickness, and grooves are opened on both sides for the baffles 27 to be inserted and sent out).

[0035] When the device is in use, the emergency power supply equipment is cooled by the ventilation duct 12 in normal state. When the emergency power supply equipment is enabled to supply power to the communication base station or to charge and store energy, more heat will be dissipated. The mounting plate 23 is opened by the driving component 3. In this state, the air inlets 21 on both sides of the rain cover 2 are opened. Through the action of the heat dissipation fan inside the blockage, air passes through the air inlet 21, the blockage and the ventilation duct 12, and the emergency power supply equipment in the cabinet 1 is efficiently cooled. The heat dissipation process is due to the outlet direction of the ventilation duct 12 and the peripheral arrangement of the air inlet 21. There is a cover 22, which is covered by a baffle 27 when not in use, so that it can be better suitable for the environment near the outdoor communication base station, and it can also save the inconvenience of frequent manual adjustment. The electric push rod 31 drives the connecting frame 32 to rise, and the mounting plate 23 is lifted away from the storage slot position of the rain cover 2 through the fixed connection between the connecting shaft 33 and the ear plate 34, until the plug-in plate 310 is plugged into the slot 35. In this part, first, the plug-in position of the driving shaft 39 and the connecting shaft 33 is the position where the mounting plate 23 can be rotated after moving, and it will not collide with the rain cover 2. The tearing force of the rotation can also separate the sealing strip 28. The position of the plug plate 310 corresponds vertically to the slot 35. When the connecting shaft 33 moves vertically, it is plugged into the driving shaft 39. The motor 36 drives the two sets of staggered transmission belts 38 to transmit the kinetic energy to the two driving shafts 39, and the mounting plate 23 is flipped through the two driving shafts 39 respectively. The flipping angle can be adjusted to make the inner solar panel receive sunlight better. When the connecting frame 32 is at the bottom, the bottom squeezes the support plate 4, and then the support plate 4 pulls the pull rope to move downward, and the sweeping plate 25 moves along the sliding The groove 26 moves to the position of the drain groove 24 to cover the drain groove. In this state, when not in use, the rain cover 2 is sealed and protected to a certain extent to reduce the entry of dust and rainwater to damage the electrical appliance. Similarly, when the connecting frame 32 moves upward, the support plate 4 is not limited by squeezing, and the return spring 29 drives the sweeping plate 25 to move to the top of the middle position of the dustproof net 14. In this state, when the mounting plate 23 is retracted next time, the sweeping plate 25 can clean the dust on the surface of the dustproof net 14 and push it out of the drain groove 24 to maintain the dustproof net 14 without dust accumulation.
