DETAILED DESCRIPTION

[0025] 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.

[0026] See also Figure 1-7 The present invention provides a technical solution for an emergency power supply device for power supply of a 5G base station power grid. The detailed connection method is a well-known technology in the art. The following mainly introduces the working principle and process. The specific work is as follows.

[0027] An emergency power supply device for power supply of a 5G base station power grid comprises: a main shell 1, a sub-shell 2, a support tube 3, an auxiliary mechanism 4, a liquid supply mechanism 5 and a connecting assembly 6. The inner cavity of the main shell 1 is a cubic cavity structure. The top of the main shell 1 is a detachable structure, which is convenient for installing and debugging the components inside the main shell 1. At the same time, a sealing strip is used between the detachable top cover of the main shell 1 and the main shell 1 to ensure the sealing of the joint. At the same time, a waterproof and breathable valve is provided on the top end surface of the main shell 1, including but not limited to a hydrophobic membrane valve, so as to ensure that when liquid is injected into the main shell 1, it is avoided that the pressure inside the main shell 1 causes the liquid to be unable to be injected into the main shell 1, and liquid is extracted from the main shell 1. A rotatable lever 7 is provided on the top surface of the main shell 1. The sub-shell 2 is a cubic structure, and the sub-shell 2 is located at the geometric center of the main shell 1. A power supply is installed in the inner cavity of the sub-shell 2, and the power supply is connected to the electrical appliances outside the main shell 1 through a wire. The sub-shell 2 adopts a split structure, and the sub-shell 2 has good thermal conductivity, and the heat of the power supply in its inner cavity can be conducted out of the sub-shell 2. At the same time, the sub-shell 2 adopts a split structure, and the power supply in the sub-shell 2 can be disassembled, repaired, etc. The number of support tubes 3 is eight, and the first ends of the eight support tubes 3 are arranged on the outer walls of the eight vertex corners of the sub-shell 2, and the second ends of the eight support tubes 3 are arranged on the inner walls of the eight vertex corners of the main shell 1, and the second ends of the eight support tubes 3 extend out of the main shell 1, and the support tubes 3 can be changed by filling and discharging liquid in the support tubes 3. Whether it is in a filled state, when the support tube 3 is full of liquid, the outer wall of the support tube 3 is in a taut state, which can generate a supporting force. The eight support tubes 3 are used to support the sub-shell 2 at the geometric center of the main shell 1. At the same time, since the support tube 3 is full of liquid, the support tube 3 can produce a slight deformation at this time, and can shake within a certain range, so as to achieve a shock absorption effect. When the liquid in the support tube 3 is drawn out, the support tube 3 shrinks, and the eight support tubes 3 will lose the supporting force. At this time, the eight support tubes 3 are in a traction state, which will play a role in limiting the movement range of the sub-shell 2. The length of the support tube 3 can ensure that the sub-shell 2 will not collide with the inner wall of the main shell 1 within the moving range of the inner cavity of the main shell 1. The number of auxiliary mechanisms 4 is four, and the four auxiliary mechanisms 4 It is arranged on the outer wall of the main shell 1, and the two ends of each auxiliary mechanism 4 are respectively connected to the second ends of the two support tubes 3. The auxiliary mechanism 4 can control the filling state of the support tube 3 to change, so as to realize that the support tube 3 is in a supporting state or a traction state. The liquid supply mechanism 5 is arranged on the side wall of the main shell 1. By controlling the liquid supply mechanism 5, the cavity between the main shell 1 and the auxiliary shell 2 is filled with liquid, and the liquid is used to achieve the effect of shock absorbing and improving the heat dissipation of the power supply in the auxiliary shell 2. The connecting component 6 is connected between the auxiliary mechanism 4 and the liquid supply mechanism 5. The connecting component 6 is used to link the liquid supply mechanism 5 and the auxiliary mechanism 4 to ensure that when the main shell 1 is full of liquid, the support tube 3 is in a traction state, and vice versa. The support tube 3 is in a supporting state.

[0028] More specifically, the liquid supply mechanism 5 includes: a fixed shell 51, a water bag 52, a first connecting pipe 53, a pressing plate 54 and an operating assembly 55. The fixed shell 51 is installed on the outer wall of the main shell 1. The outer end surface of the fixed shell 51 is open. The top of the annular outer wall of the fixed shell 51 is provided with an opening to realize the installation and removal of the water bag 52. The water bag 52 is placed in the inner cavity of the fixed shell 51. The two side end surfaces of the water bag 52 are bonded with a rubber surface. The bonding force generated by the rubber surface is greater than the pulling force required for pumping water when the water bag 52 is in a deflated state. The first end of the first connecting pipe 53 is connected to the water bag 52. The second end of the first connecting pipe 53 passes through the outer wall of the fixed shell 51 and is connected to the outer wall of the main shell 1. The first connecting pipe 53 is connected to the water bag 52 are detachably connected, and relative displacement can occur between the first connecting tube 53 and the fixed shell 51, ensuring convenience when installing and taking out the water bag 52. The pressing plate 54 is arranged in the inner cavity of the fixed shell 51 and is slidably arranged at the open end of the fixed shell 51. The pressing plate 54 can only be translated along the axial direction of the fixed shell 51 and cannot rotate. The inner end surfaces of the pressing plate 54 and the fixed shell 51 are both horizontal planes, ensuring that the water bag 52 is thoroughly squeezed when the pressing plate 54 moves to the side of the water bag 52, which is enough to fill the inner cavity of the main shell 1 with liquid. The operating component 55 is arranged on the outer end surface of the fixed shell 51, and the operating component 55 can control the movement of the pressing plate 54 to realize the filling and discharging state of the water bag 52.

[0029] Furthermore, the operating assembly 55 includes: a base tube 551, a bracket 552, a driving tube 553, a push rod 555, a push handle 556 and a limit ring 558. The base tube 551 is arranged at the axial position of the open end surface of the fixed shell 51. The annular outer wall of the base tube 551 is provided with a slot and a through groove. The through groove penetrates into the inner cavity of the base tube 551. The slot and the through groove are distributed in a mirror image. The base tube 551 is arranged on the open end surface of the fixed shell 51 through the bracket 552 to limit the movement of the pressure plate 54. The slot does not penetrate the tube wall of the base tube 551 to the inner cavity of the base tube 551, and the through groove penetrates the tube wall of the base tube 551 to the inner cavity of the base tube 551. The slot and the through groove are both opened along the vertical radial direction of the base tube 551. The driving tube 553 is rotatably arranged in the inner cavity of the base tube 551. The annular outer wall of the driving tube 553 is provided with a tooth groove 554. The position of the tooth groove 554 corresponds to the position of the through groove. The driving tube 553 can only be moved along the axis of the base tube 551. The push rod 555 can be rotated but cannot be translated in the axial direction. The push rod 555 is screwed to the inner cavity of the driving tube 553. The end of the push rod 555 is fixedly connected to the pressing plate 54. The push rod 555 can only be translated in the direction of the base tube 551 along with the pressing plate 54. With this restriction, when the driving tube 553 rotates, the push rod 555 will be translated in conjunction with the screw connection between the push rod 555 and the driving tube 553, thereby pushing the pressing plate 54 to move to one side, generating pressure or tension on the water bag 52, and pushing the water bag 52 to move to the other side. The handle 556 is sleeved on the slot and the through slot, and the inner wall of the push handle 556 is provided with teeth 557 matching the tooth groove 554. The push handle 556 is a U-shaped structure, and the two long sides of the push handle 556 are distributed in the vertical direction. The push handle 556 cooperates with the slot and the through slot to ensure that the push handle 556 moves in the vertical direction. At the same time, a limiting ring 558 is provided on the outer end surface of the fixed shell 51, and the push handle 556 is located in the limiting ring 558 to ensure that the push handle 556 is displaced in the vertical direction.

[0030] More specifically, the auxiliary mechanism 4 includes: an auxiliary tube 41, a support shaft 42, a swing arm 43, a piston 44 and a connecting arm 45. The auxiliary tube 41 is arranged on the outer wall of the main shell 1, and the two ends of the auxiliary tube 41 are respectively connected to the two support tubes 3. The auxiliary tube 41 can be arranged in a horizontal direction or a vertical direction. The auxiliary tube 41 is arranged at the connection between each two surfaces of the main shell 1, and each auxiliary tube 41 is connected to the support tubes 3 at both ends of the edge. Each auxiliary tube 41 controls the state of the two support tubes 3. The support shaft 42 is arranged on the auxiliary tube 41 to rotate radially along the auxiliary tube 41, and the end of the support shaft 42 extends out of the outer wall of the auxiliary tube 41. The support shaft 42 is connected to the connecting component 6, and the swing arm 43 is located in the inner cavity of the auxiliary tube 41, and The center position of the swing arm 43 is set on the support shaft 42, and the swing arm 43 rotates with the support shaft 42. The rotation angle of the swing arm 43 is between 0°-75°. When 0°, the swing arm 43 is in a horizontal state, which is a suction state. When the swing arm 43 is at 75°, it is an injection state. There are two pistons 44, and the two pistons 44 are mirror-mounted in the inner cavity of the auxiliary tube 41. Through the movement of the piston 44, the liquid in the auxiliary tube 41 is injected into the support tube 3. The piston 44 only translates along the axis of the auxiliary tube 41. There are two connecting arms 45, and the two connecting arms 45 respectively connect the two ends of the swing arm 43 and the two pistons 44. The connecting arms 45 are used to convert the rotational motion of the swing arm 43 into a force that pushes the piston 44 to translate.

[0031] Furthermore, the support tube 3 is made of elastic material. When the support tube 3 is filled with liquid, it has a tubular structure and can bend and deform to a certain extent. While ensuring that there is no collision between the sub-shell 2 and the inner wall of the main shell 1, the sub-shell 2 is supported in the inner cavity of the main shell 1 to achieve a shock-absorbing effect. When the support tube 3 is not filled with liquid, the support tube 3 is in a deflated state, and the support tube 3 plays a supporting role to prevent the sub-shell 2 from colliding with the inner wall of the main shell 1 when floating in the liquid of the main shell 1.

[0032] Furthermore, the sub-shell 2 is made of lightweight material and a closed air cavity is provided inside the sub-shell 2. The buoyancy generated by the sub-shell 2 in the liquid matches the gravity of the sub-shell 2 and the power supply in the inner cavity of the sub-shell 2. When no external force is applied, the sub-shell 2 is ensured to float in the liquid of the main shell 1.

[0033] Furthermore, the number of liquid supply mechanisms 5 is two or four, and the total capacity of the water bags 52 in all the liquid supply mechanisms 5 matches the capacity of the main shell 1. When the number of liquid supply mechanisms 5 is two, each liquid supply mechanism 5 is connected to two adjacent auxiliary mechanisms 4 through a connecting assembly 6. When the number of liquid supply mechanisms 5 is four, each liquid supply mechanism 5 will be connected to one auxiliary mechanism 4.

[0034] Furthermore, the maximum capacity between the two pistons 44 and the auxiliary tube 41 is greater than the capacity of the two support tubes 3, ensuring that each support tube 3 can be completely filled to a supporting state, or completely drained to a traction state.

[0035] Furthermore, the connecting assembly 6 includes: a fixing ring 61, a connecting rod 62 and a second connecting arm 63, the fixing ring 61 is fixedly arranged at the end of the driving tube 553, the second connecting arm 63 is arranged on the outer wall of the support shaft 42, the first end of the connecting rod 62 is rotatably arranged on the outer wall of the fixing ring 61, and the second end of the connecting rod 62 is rotatably arranged at the end of the second connecting arm 63. When the number of liquid supply mechanisms 5 is two, two connecting rods 62 are arranged on each fixing ring 61, which are respectively connected to the connecting arms 45 on the two auxiliary mechanisms 4.

[0036] Furthermore, the liquid in the water bag 52 and the liquid in the inner cavity of the auxiliary tube 41 are made of liquid with high thermal conductivity and non-conductive properties to prevent the liquid from becoming a conductor, causing damage to the power supply and causing danger. At the same time, the top of the push handle 556 of each liquid supply mechanism 5 is connected by a handle 8, and the state of the liquid supply mechanism 5 is changed by pushing and pulling the handle 8. At the same time, the lever 7 on the top surface of the main shell 1 can clamp the handle 8 to fix the position of the handle 8.

[0037] Working principle:

[0038] In an emergency situation where the vibration is relatively minor, the water bag 52 can be removed to ensure the portability of the entire device. The device and the water bag 52 can be transported separately in the transport state. The water bag 52 can be installed at a location where strong vibration occurs. When the water bag 52 is not installed, the handle 8 is in a pulling state. At this time, the distance between the pressure plate 54 and the outer wall of the main shell 1 is at the maximum state. Through the connecting component 6, the swing arm 43 is in an injection state. The liquid in the auxiliary tube 41 is all located in the support tube 3. The power supply is connected to the base station. At this time, the power supply is in a state supported by the support tube 3. The shock absorption effect is achieved by using eight support tubes 3 filled with liquid. The air between the main shell 1 and the auxiliary shell 2 is a heat dissipation medium. At this time, the total amount of liquid in the device, that is, the amount of liquid in the eight support tubes 3, is relatively small in weight and has portability.

[0039] If the environment is in a particularly vibrating environment, the supporting force of the eight support tubes 3 will be insufficient, and the support tubes 3 may be easily damaged. At this time, the water bag 52 may be connected to the first connecting tube 53, and the water bag 52 may be placed in the fixed shell 51 so that the water bag 52 is bonded to the inner wall of the fixed shell 51 and between the pressure plate 54. At this time, the handle 8 is pressed downward, and the push handle 556 moves synchronously with the pressing of the handle 8. The driving tube 553 rotates by utilizing the cooperation of the teeth 557 and the tooth grooves 554, and the push rod 555 moves along the axial direction of the driving tube 553. The pressure plate 54 squeezes the water bag 52. At this time, the liquid in the water bag 52 enters the main shell 1 through the first connecting tube 53. At the same time, through the connecting component 6, the swing arm 43 changes from the injection state to the suction state. With the injection of liquid in the main shell 1, the liquid in the support tube 3 is gradually drawn back into the auxiliary tube 41. At this time, the sub-shell 2 is located in the liquid and is pulled by eight deflated support tubes 3. The liquid will reduce the shock of the sub-shell 2 and the power supply. At the same time, the liquid is a heat dissipation medium, which makes the power supply have better shock absorption and heat dissipation effects.
