They are transmission lines with inherent strength, real-time perception, holographic interconnection, autonomous early warning, and intelligent disposal.

[0003] In the prior art, safe monitoring of electrical parameters in smart power is achieved through circuit monitoring devices, such as the three-phase multi-circuit monitoring device model AMC96N-4E3, whose internal circuit monitoring device is mainly used for monitoring electrical parameters of multiple distribution circuits. It centrally measures and displays the bus voltage in the circuit, the current, power, and electric energy of multiple distribution circuits, and can centrally monitor and display the switch status of each circuit. The above parameters can also be communicated and output, realizing centralized measurement and monitoring of distribution line circuits with simpler monitoring requirements.

[0004] However, the circuit boards used in existing circuit monitoring devices are usually directly welded inside the casing. When the welding connection causes the circuit board to be damaged and needs to be repaired, removing the circuit board may damage the casing.

[0008] The top and bottom of the shell are rotatably installed with a first transmission screw and a second transmission screw which are arranged in parallel and have threaded sections with different threaded directions at both ends; the first transmission screw and the second transmission screw are respectively connected to a first slider and a second slider at both ends by threaded engagement; the first slider and the first pressure plate, as well as the second slider and the second pressure plate at both ends are rotatably connected by a telescopic rod; a second spring elastically connected is sleeved between the first pressure plate and the second pressure plate and the telescopic rod.

[0009] As a further description of the above technical solution: the first pressing plate and the second pressing plate are elastically connected via a first spring.

[0013] As a further description of the above technical solution: the first pressing plate and the second pressing plate are both rotatably connected to the housing via a rotating shaft.

[0014] In summary, due to the adoption of the above technical solution, the beneficial effects of the present invention are:

[0015] 1. In the present invention, through the synchronous forward rotation of the first transmission screw and the second transmission screw, according to the principle of screw transmission, the first slider and the second slider are driven to move outward, and under the connection action of the telescopic rod, the first pressure plate and the second pressure plate are driven away from the circuit board, thereby releasing the fixation of the circuit board in the housing.

[0023] 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.

[0024] See also Figure 1-4 A control device for smart circuit safety monitoring includes a housing 1 with a circuit monitoring device inside, a display screen 2 and a control button 3 are arranged on the outside of the housing 1, a circuit board 4 is arranged inside the housing 1, and a first pressing plate 13 and a second pressing plate 11 are symmetrically arranged and rotatably mounted on the inner surface walls on both sides of the housing 1, the first pressing plate 13 and the second pressing plate 11 are rotatably connected to the housing 1 through a rotating shaft, and the circuit board 4 is located between the first pressing plate 13 and the second pressing plate 11 on both sides;

[0025] The top and bottom of the housing 1 are both rotatably mounted with a first transmission screw 7 and a second transmission screw 5 which are arranged in parallel and have threaded sections at both ends with different threaded directions. The first transmission screw 7 and the second transmission screw 5 are respectively connected with a first slider 14 and a second slider 8 at both ends by threaded engagement. The first slider 14 and the first pressing plate 13 at both ends, as well as the second slider 8 and the second pressing plate 11 are rotatably connected by a telescopic rod 9. The first pressing plate 13 and the second pressing plate 11 are both sleeved with an elastically connected second spring 10, and a pressure pointing to the direction of the circuit board 4 is applied to the first pressing plate 13 and the second pressing plate 11 from the outside through the second spring 10 in a compressed state, thereby improving the fixing stability of the first pressing plate 13 and the second pressing plate 11 to the circuit board 4;

[0026] Through the synchronous forward rotation of the first transmission screw 7 and the second transmission screw 5, according to the principle of thread transmission, the first slider 14 and the second slider 8 are driven to move outward, and under the connection action of the telescopic rod 9, the first pressure plate 13 and the second pressure plate 11 are driven away from the circuit board 4, so that the circuit board 4 is released from the fixing in the housing 1. Compared with the traditional welded circuit board 4, it is convenient to take and place the circuit board 4, so as to facilitate the inspection and replacement of the components on the circuit board 4.

[0027] Specifically, Figure 2 As shown, the first pressure plate 13 and the second pressure plate 11 are elastically connected via the first spring 12. When the first spring 12 is in a compressed state, a pressure pointing in the direction of the circuit board 4 is applied to the first pressure plate 13 and the second pressure plate 11 from the inside, thereby improving the fixing stability of the first pressure plate 13 and the second pressure plate 11 to the circuit board 4.

[0028] Specifically, Figure 1-3 As shown, the first transmission screw 7 and the second transmission screw 5 are connected via a belt 6. Under the transmission action of the belt 6, the second transmission screw 5 is driven to rotate synchronously through the rotation of the first transmission screw 7, so that the first pressure plate 13 and the second pressure plate 11 are synchronously approached or moved away from the circuit board 4, which is convenient for the disassembly and assembly of the circuit board 4. The structure is simple and the operation is convenient.

[0029] Specifically, Figure 2 As shown, rubber pads 16 are bonded to the bottom of the first pressing plate 13 and the second pressing plate 11 to increase the friction between the contact surfaces of the first pressing plate 13 and the second pressing plate 11 and the circuit board 4 and improve the fixing stability of the circuit board 4 in the housing 1.

[0030] Specifically, Figure 2 and Figure 4 As shown, a plurality of heat dissipation holes 17 are opened on one side of the shell 1, and the heat in the shell 1 is dissipated through the heat dissipation holes 17. A plurality of heat dissipation fans 15 are fixedly installed at the bottom of the shell 1, and the heat dissipation of the circuit board 4 is performed by the heat dissipation fans 15, thereby improving the heat dissipation effect of the circuit board 4.

[0031] The working principle of the present invention is: when in use, first, through the synchronous forward rotation of the first transmission screw 7 and the second transmission screw 5, according to the principle of thread transmission, the first slider 14 and the second slider 8 are driven to move outward, and under the connection action of the telescopic rod 9, the first pressure plate 13 and the second pressure plate 11 are driven away from the circuit board 4, thereby releasing the fixation of the circuit board 4 in the housing 1. Compared with the traditional welded circuit board 4, it is convenient to take and place the circuit board 4, thereby facilitating the inspection and replacement of components on the circuit board 4.

[0032] Secondly, the circuit board 4 is cooled by the cooling fan 15 , and the heat in the housing 1 is dissipated through the cooling holes 17 , thereby improving the heat dissipation effect of the circuit board 4 .

[0033] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
