Description

Technical Field

[0001] The invention relates to the technical field of single-chip microcomputer protection, in particular to a single-chip microcomputer protection device for electrical equipment. Background Art

[0002] Electrical equipment is a general term for generators, transformers, power lines, circuit breakers and other equipment in power systems. As the actual environment has higher requirements for the use of electrical equipment, researchers in related fields are also constantly improving electrical equipment. For example, the application number is 202111021487.8 The patent document proposes "a single-chip microcomputer protection device for electrical equipment, comprising an electrical equipment body and a cabinet door, the cabinet door being hinged on the outer wall of the electrical equipment body, the front outer wall of the cabinet door being provided with an installation opening, and a single-chip microcomputer control device being installed in the inner cavity of the installation opening, the single-chip microcomputer control device comprising a control device body inserted in the inner cavity of the installation opening, a mounting frame being installed on the front outer wall of the control device body, the rear side wall of the mounting frame being connected to the front side wall of the cabinet door, the outer wall of the control device body being sleeved with an elastic sleeve block, the outer wall of the elastic sleeve block being fitted with the inner wall of the installation opening", and after use, "the device is compensated by the expansion and contraction of the elastic sleeve block, so that the cabinet door will not directly squeeze the control device body when it is deformed, thereby reducing the squeezing force on the single-chip microcomputer control device; the guide block slides in the inner cavity of the guide groove, so that the connecting card block can slide on the rear side of the mounting frame, and the mounting frame will not be squeezed when the cabinet door is deformed".

[0003] However, it can be seen from the above-mentioned disclosed technical content that the prior art protects the single-chip microcomputer of the electrical equipment by means of elastic structure buffering and rigid structure pressure resistance, so as to prevent it from being damaged in the accident where the cabinet door is hit and deformed. However, from a realistic perspective, the external force that can cause the deformation of the cabinet door must be extremely large, and the single-chip microcomputer of the electrical equipment and the cabinet door in the prior art are in an integrated fixed installation relationship. Only the elastic buffering and the direct pressure and deformation resistance of the rigid structure are very effective, and the probability of damage to the single-chip microcomputer is still very high.

[0008] Selectedly, the four inner walls of the outer protective frame plate are installed with elastic folding airbags, and a composite air guide pipe fitting is arranged outside the rear end of the single-chip computer. The input structure of the composite air guide pipe fitting is connected to the middle part of the main air pipe.

[0009] The composite air guide pipe comprises a first solenoid valve tube, an annular tube and four branch pipes. The first solenoid valve tube is installed between the middle part of the main air pipe and the annular tube as the input structure of the composite air guide pipe. The four branch pipes are all used as the output structure of the composite air guide pipe and are respectively installed between four elastic folded airbags and the annular tube. The composite air guide pipe provides structural conditions for the synchronous use of the four elastic folded airbags.

[0010] Preferably, guide grooves are provided on the surfaces of both sides of the single-chip computer, and the number of guide grooves is not less than two and is evenly distributed on the sides of both sides of the single-chip computer, and multiple guide grooves are used to increase the heat dissipation area of ​​subsequent cooling air convection of the single-chip computer.

[0011] Preferably, a second solenoid valve tube is installed at the bottom of the main air supply pipe, and an auxiliary flow groove aligned with the guide groove is opened on the side wall at the open port of the second solenoid valve tube.

After the surround protection component and the abnormality detection component are further combined and used with the above-mentioned storage protection device and the guide support component, when the cabinet door is compressed and deformed, the transition connection sleeve in the guide support assembly is compressed and broken, and the push rod and the pressure sensor are connected. The pressure data of the pressure sensor disappears as an abnormal warning situation, and then the air pump and the main air pipe are linked to supply air to the composite air guide pipe parts, so that the four elastic folding airbags are finally expanded and deformed in the outer protection frame plate, and then the single-chip microcomputer in an independent state is surrounded by buffer protection.

A composite air guide pipe 9 is provided outside the rear end of the single chip 2, and the input structure of the composite air guide pipe 9 is connected to the middle part of the main air pipe 6. Four output structures are provided in the composite air guide pipe 9, and the four output structures extend to the internal sets of four elastic folding airbags 10 respectively. The composite air guide pipe 9, as an extension of the conveying flow channel of the main air pipe 6, can provide structural conditions for the linkage operation of the four elastic folding airbags 10 and the subsequent main air pipe 6 and the air pump 4; The composite air guide pipe 9 includes a first electromagnetic valve pipe 91, an annular pipe 92 and four branch pipes 93. The first electromagnetic valve pipe 91 is installed between the middle of the main air pipe 6 and the annular pipe 92 as the input structure of the composite air guide pipe 9. The four branch pipes 93 are installed between the four elastic folded air bags 10 and the annular pipe 92 as the output structure of the composite air guide pipe 9. The composite air guide pipe 9 provides structural conditions for the synchronous use of the four elastic folded air bags 10. The surfaces of both sides of the single-chip computer 2 are provided with guide grooves, and the number of guide grooves is not less than two and is evenly distributed on the side surfaces on both sides of the single-chip computer 2. Multiple guide grooves are used to increase the heat dissipation area of ​​subsequent cooling air convection of the single-chip computer 2. A second solenoid valve tube 11 is installed at the bottom of the main air supply pipe 6. The side wall at the open port of the second solenoid valve tube 11 is provided with an auxiliary flow groove aligned with the guide groove. The second solenoid valve tube 11 is used as a channel for releasing the air inside the folding top pressure airbag 5. While maintaining the sustainable use effect of the folding top pressure airbag 5, the airflow is transported to the auxiliary flow groove to assist in improving the self-heating effect of the single-chip computer 2. A plurality of ventilation grooves 12 are provided at the rear end of the outer protective frame plate 3, and the plurality of ventilation grooves 12 are equidistantly distributed on the rear end structure of the outer protective frame plate 3, providing an air circulation channel for the self-heating of the single-chip computer 2 during operation.

[0021] The working process of the single-chip protection device for electrical equipment of the present invention is as follows: For the use of the single-chip computer 2, the air pump 4 is started, and the output end of the air pump 4 delivers air to the inside of the folding top pressure airbag 5 through the main air supply pipe 6, so that the folding top pressure airbag 5 expands and deforms to press the single-chip computer 2, so that the single-chip computer 2 moves toward the development structure of the front end of the outer protection frame plate 3 under the guidance of multiple transition connection sleeves 7 and U-shaped rods 8, until the folding top pressure airbag 5 expands to the maximum stroke, and the air pump 4 is turned off; At this time, the front operating surface of the single-chip microcomputer 2 is close to the development structure of the front end of the outer protective frame plate 3. The user directly uses the single-chip microcomputer 2. After use, the solenoid valve on the second solenoid valve tube 11 is opened, and the air inside the folding top pressure airbag 5 is discharged through the second solenoid valve tube 11 for reset. During the diversion process of the second solenoid valve tube 11, the air fully contacts the diversion grooves on the sides of the single-chip microcomputer 2, and the single-chip microcomputer 2 after use is cooled by air blowing.

[0022] For active air blowing heat dissipation of the single-chip microcomputer 2, start the air pump 4, and deliver air from the output end of the air pump 4 to the folding top pressure airbag 5, the second solenoid valve tube 11 and other structures through the main air supply pipe 6. At the same time, open the solenoid valve on the second solenoid valve tube 11, and the air will be delivered to the guide groove on the side of the single-chip microcomputer 2 through the tube body of the second solenoid valve tube 11, so that the air can fully contact the guide grooves on the sides of the single-chip microcomputer 2, and the single-chip microcomputer 2 after use can be actively cooled by air blowing.

[0023] When the cabinet door 1 is deformed by an accidental impact, the transition connecting plate 7 and the U-shaped rod 8 synchronously receive the deformation pressure of the cabinet door 1, and the transition connecting plate 7 will break after the received pressure reaches a normal level due to the easy-to-break grooves provided therein, thereby, the push rod 15 and the pressure sensor 13 are changed from being tightly fitted, so that the pressure sensor 13 generates pressure data, to being separated from the push rod 15 and the pressure sensor 13, so that the pressure sensor 13 does not generate pressure data and performs abnormal expression, and the single-chip computer 2 will also be in a relatively independent state; After the existing control system receives the abnormal expression, it will synchronously start the air pump 4 and open the solenoid valve on the first solenoid valve tube 91. Subsequently, the output end of the air pump 4 enters the interior of the branch pipe 93 through the main air supply pipe 6, and then quickly enters the interior of the four elastic folding airbags 10 through the four branch pipes 93, so that the four elastic folding airbags 10 can quickly expand the fault, and then the single-chip microcomputer 2 in a relatively independent state is surrounded by buffer protection, thereby fully protecting the single-chip microcomputer 2.
