[0034] 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.

[0035] Embodiment 1

[0036] like Figure 1-8 As shown, a distribution box capable of automatic detection and alarm comprises a distribution box body 1, and a liquid level sensor 6 for detecting the amount of water entering the distribution box body 1 is provided on the inner wall of one side of the distribution box body 1. When the liquid level sensor 6 detects that water has entered the distribution box body 1, it will send an alarm to the alarm center through the controller 7, reminding the outside that the distribution box body 1 has been flooded and that emergency repair personnel are needed to come and deal with it. At the same time, the controller 7 will also send a signal to control the motor 21 to start working, and drain the accumulated water in the distribution box body 1. A storage slot 16 for placing the probe of the liquid level sensor 6 is provided on the inner wall of one side of the distribution box body 1. The storage slot 16 is located at the inclined bottom wall of the distribution box body 1. On the surface, it is convenient for the probe of the liquid level sensor 6 to quickly detect the water level. The interior of the storage tank 16 is provided with a sealing plastic sheet 61 slidably connected to the surface of the probe of the liquid level sensor 6. The sealing plastic sheet 61 will slide upward with the rise of the water level. The bottom wall of the inner cavity of the distribution box body 1 is provided with an operating mechanism 2 for squeezing and moving. The operating mechanism 2 utilizes the mutual squeezing of various components to lift the distribution box body 1, thereby facilitating the discharge of seepage water in the distribution box body 1. A part of the bottom wall of the inner cavity of the distribution box body 1 away from the operating mechanism 2 is an inclined surface with a high front and a low back, which is convenient for detecting the water ingress into the distribution box body 1 and facilitating the discharge of accumulated water in the distribution box body 1.

[0037] For details, please refer to Figure 2-3The operating mechanism 2 includes a motor 21 and a fixed plate 22 fixedly connected to the bottom wall of the inner cavity of the distribution box body 1. When the adjustment plate 24 rotates to a horizontal state, the adjustment block 23 and the fixed plate 22 touch each other to prevent the adjustment block 23 from moving too much, resulting in the distribution box body 1 being lifted, and the accumulated water falling before being completely discharged, resulting in incomplete drainage and affecting the safety of electrical components. The motor 21 and the fixed plate 22 are located in the same vertical plane, and the output end of the motor 21 is provided with a threaded rod 28 through a coupling. The end of the threaded rod 28 away from the motor 21 is rotatably connected to the fixed plate 22, and the outer surface of the threaded rod 28 is provided with an adjustment block 23 for moving and squeezing. The adjustment block 23 is threadedly connected to the outer surface of the threaded rod 28, and then the rotation of the threaded rod 28 is used to move back and forth on its outer surface. The left and right outer end walls of the adjustment block 23 are provided with first slots 231, and the insides of the two first slots 231 are provided with adjustment plates 24, and the adjustment plates 24 are rotatably connected to the insides of the first slots 231, and then the front and rear movement of the adjustment block 23 is used to force the adjustment plate 24 to be adjusted from an inclined state to a horizontal state, so that the two moving blocks 8 are squeezed to move to both sides by the first rotating plate 26 and the second rotating plate 27, and two slide grooves 11 are provided on the bottom wall of the inner cavity of the distribution box body 1, and the insides of the two slide grooves 11 are provided with moving rods 25, and a part of the adjustment plate 24 away from the adjustment block 23 is rotatably connected to the upper outer surface of the moving rod 25, and the moving rod 25 moves to the left and right sides of the distribution box body 1 with the rotation of the adjustment plate 24, squeezing the first rotating plate 26 and the second rotating plate 27 to rotate outward;

[0038] Specifically, in order to raise the distribution box body 1 to facilitate drainage, please refer to Figure 4-8, two opening grooves 12 are provided on the inner walls on the left and right sides of the distribution box body 1, and a first groove 13 is provided inside the four opening grooves 12 to prevent the moving block 8 from detaching from the inner wall of the distribution box body 1, resulting in the inability to discharge the seepage in the distribution box body 1 normally. The insides of the four first grooves 13 are provided with a means for moving and pressing the moving block 8. The two moving blocks 8 located in the same vertical plane move farther and farther with the horizontal movement of the moving rod 25, thereby squeezing the lifting block 9 downward, lifting the distribution box body 1, and thus facilitating the discharge of the accumulated water in the distribution box body 1. The ends of the four moving blocks 8 that are close to each other are provided with a second empty groove 81, and the insides of the four second empty grooves 81 are respectively provided with two first rotating plates 26 and two second rotating plates 27, one of which is a first rotating plate 26 and one of which is a second rotating plate 2 7 is located in the same vertical plane, and the two first rotating plates 26 are located in the same horizontal plane, that is, the left and right sides of the operating mechanism 2 are symmetrical to each other, and the first rotating plate 26 and the second rotating plate 27 located on the same side are both rotatably connected to the lower part of the outer surface of the moving rod 25 located on the same side, that is, the angle between the first rotating plate 26 and the second rotating plate 27 becomes larger and larger as the moving rod 25 moves, and the bottom walls of the two first grooves 13 located in the same vertical direction are each provided with a moving groove 14 that runs through the lower end of the distribution box body 1 on the side away from each other, and the interior of the moving groove 14 is provided with a lifting block 9 for lifting the distribution box body 1, and the lifting block 9 moves downward with the squeezing of the moving block 8, thereby lifting the distribution box body 1, and then facilitating the rapid outflow of the accumulated water in the distribution box body 1;

[0039] Further, in order to prevent the lifting block 9 from affecting the normal movement of the distribution box body 1, please refer to Figure 8 The lifting block 9 is a right-angled trapezoidal block with an inclined upper portion, and the height of the side of the lifting block 9 away from the moving block 8 is greater than the height of the side of the lifting block 9 close to the moving block 8. The moving block 8 squeezes the inclined surface of the lifting block 9 to gradually move the lifting block 9 downward, thereby raising the distribution box body 1 for drainage. The side walls of the two first grooves 13 located in the same vertical plane and away from each other are each provided with a second groove 15. The interior of the second groove 15 is provided with a pressing plate 91 for restoring the lifting block 9 to its initial state. The pressing plate 91 is fixedly connected to the end of the lifting block 9 away from the moving block 8. A spring 92 is provided between the lower end of the pressing plate 91 and the bottom wall of the second groove 15. When the distribution box body 1 is moved, the pressing plate 91 uses the spring 92 to keep the lifting block 9 in the moving groove 14 at all times to prevent the lifting block 9 from being exposed to the outside and affecting the normal movement of the distribution box body 1.

[0040] Therefore, the motor 21 is used to control the threaded rod 28 to rotate, so that the adjustment block 23 moves forward and backward on the threaded rod 28, and then the moving rod 25 is squeezed by the adjustment plate 24 to move to the left and right sides of the distribution box body 1. During the movement of the moving rod 25, the first rotating plate 26 and the second rotating plate 27 are forced to expand outward, thereby squeezing the two moving blocks 8 to move in opposite directions, and then squeezing the lifting block 9 downward, so that the distribution box body 1 is lifted and the accumulated water is discharged.

[0041] Embodiment 2

[0042] like Figure 9-12 As shown, the bottom wall of the inner cavity of the distribution box body 1 is provided with a baffle 4 for blocking the water flow, and the lower side edge of the end of the baffle 4 away from the operating mechanism 2 coincides with the side edge of the inclined surface of the bottom wall of the distribution box body 1 with a higher height. Firstly, it prevents the accumulated water from penetrating into the interior of the distribution box body 1, and secondly, it utilizes the inclined surface of the bottom wall of the distribution box body 1 to drain the accumulated water cleanly and reduce the residue.

[0043] For details, please refer to Fig. 9 The baffle 4 is provided with a liquid storage tank 41 inside, and the liquid storage tank 41 is filled with a water solution. By pouring the water solution into the air bag 5 to expand it, the storage space of the accumulated water is squeezed, thereby accelerating the discharge of the accumulated water. The end of the baffle 4 away from the operating mechanism 2 is provided with an air bag 5 for squeezing out the water flow. The air bag 5 is provided with two through grooves 42 that penetrate the inner wall of the liquid storage tank 41. The through grooves 42 are located at the lower part of the baffle 4 and the air bag 5 to facilitate the water solution in the liquid storage tank 41 to quickly enter the interior of the air bag 5 and increase the water intake of the air bag 5. The through grooves 42 are provided with a plug rod 31 inside. Under normal conditions, the plug rod 31 is inserted into the through groove 42 to block it, so as to prevent the water solution in the liquid storage tank 41 from Liquid automatically enters the airbag 5, and the outer surface of the plug rod 31 is provided with a first rubber ring 32 and a second rubber ring 33 for sealing. The distance between the first rubber ring 32 and the second rubber ring 33 is equal to the length of the through groove 42, so as to prevent the aqueous solution in the liquid storage tank 41 from penetrating into the airbag 5. A push rod 3 is provided at one end of the plug rod 31 close to the operating mechanism 2, and a part of the push rod 3 away from the baffle 4 is connected to the first rotating plate 26 through a universal joint. The universal joint is used to make the push rod 3 move toward the operating mechanism 2 as the first rotating plate 26 rotates, so as to pull the plug rod 31 out of the liquid storage tank 41, so that the airbag 5 will be filled with water and expanded only when water enters the distribution box body 1, and the water will be squeezed out;

[0044] Further, in order to quickly discharge the accumulated water in the storage tank 16, please refer to Figure 10-12The outer surface of the airbag 5 is provided with an air cushion 52 located inside the storage tank 16 for pressing and draining water, and the air cushion 52 is interconnected with the inner cavity of the airbag 5, so that the aqueous solution flowing into the airbag 5 can enter the inner side of the air cushion 52. The air cushion 52 is wrapped around the outer side of the probe of the liquid level sensor 6 and is fixedly connected to the upper end of the sealing plastic sheet 61. After the air cushion 52 is filled with water and expands, it becomes heavier and squeezes the sealing plastic sheet 61, so that it moves down quickly to squeeze out the accumulated water in the storage tank 16. The inner cavity of the airbag 5 is provided with a first elastic membrane 51 for guidance. The first elastic membrane 51 separates the two through grooves 42, so that the aqueous solution flowing into one of the through grooves 42 will first enter the air cushion 52, thereby quickly emptying the accumulated water in the storage tank 16, so that the liquid level sensor 6 no longer continues to generate signals, and then the motor 21 stops working. The first elastic membrane 51 divides the inner cavity of the airbag 5 into a first flow cavity 56 and a second flow cavity 57. The interior of the air cushion 52 is provided with a second The elastic membrane 53 and the second elastic membrane 53 separate the inner cavity of the air cushion 52 into a first transfer cavity 54 and a second transfer cavity 55. The first transfer cavity 54 and the second transfer cavity 55 are respectively connected with the second flow cavity 57 and the first flow cavity 56, so that the aqueous solution flowing through one of the through grooves 42 will first enter the air cushion 52 through the second flow cavity 57 and the first transfer cavity 54, so that the air cushion 52 is filled with water and expanded, and then flows into the first flow cavity 56 through the second transfer cavity 55, so that the airbag 5 is expanded. A controller 7 for alarm is provided on the inner wall of one side of the distribution box body 1. The controller 7 is electrically connected with the liquid level sensor 6 and the motor 21. When the accumulated water in the distribution box body 1 reaches a certain level, the liquid level sensor 6 will send a signal to the controller 7, and then the controller 7 controls the motor 21 to start working, and at the same time, it will send a signal to the alarm center to alarm, reminding the outside that the distribution box body 1 has been flooded and maintenance personnel are needed to come and deal with it.

[0045] Therefore, the present invention has two working stages, which are as follows:

[0046] The first stage is the alarm processing stage:

[0047] When the amount of water in the distribution box body 1 reaches a certain level, that is, the accumulated water has entered the storage tank 16, the liquid level sensor 6 will send a signal to the controller 7, and then the controller 7 controls the motor 21 to start working, so that the entire operating mechanism 2 is adjusted in position, so that the lifting block 9 moves down, thereby raising the distribution box body 1, and at the same time, a signal is sent to the alarm center to warn the outside that the distribution box body 1 has been flooded and staff are needed to come over to check and deal with it;

[0048] The second stage is the drainage stage:

[0049] While working in the first stage, the first rotating plate 26 will pull the push rod 3 through the universal joint to move in the direction of the operating mechanism 2, thereby opening the through groove 42, allowing the aqueous solution in the liquid storage tank 41 to flow into the airbag 5, causing it to expand and squeeze the storage space of the accumulated water, thereby accelerating the discharge of the accumulated water. At the same time, part of the aqueous solution will first enter the air cushion 52 under the drainage of the first elastic membrane 51, causing it to be filled with water and increase its weight, squeezing the sealing plastic sheet 61 to move downward, and quickly draining the accumulated water in the storage tank 16, thereby stopping the liquid level sensor 6 from working, and then stopping the alarm reminder to the alarm center, and at the same time stopping the motor 21 from working, preventing the adjustment block 23 from continuing to move, causing damage to the fixed plate 22, and increasing the maintenance cost of the distribution box body 1.

[0050] It should be noted that the specific installation methods and circuit arrangement and connection methods of the motor 21, liquid level sensor 6 and controller 7 used in the above embodiments are conventional designs in the prior art and will not be elaborated in detail in the present invention.

[0051] The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
