[0015] Compared with the prior art, the present invention has the following beneficial effects: The present invention realizes the formation of a single pressure-resistant structure by providing a pressure-resistant fireproof device, that is, a pressure-resistant frame can be connected to the outside of the main body of the current sensor shell, and the upper baffle and the side baffle installed on the outside of the pressure-resistant frame can realize the formation of a double pressure-resistant structure to significantly enhance the pressure-resistant effect of the shell, and a heat dissipation component is provided, that is, by running the heat dissipation fan, the wind discharge of the heat generated in the detection process can be realized, and the occurrence of the problem of spontaneous combustion due to excessive temperature can be reduced, and the linkage cooperation between the drive box and the transmission structure can make the heat dissipation fan move back and forth to dissipate heat and increase its heat dissipation range, and the front and back reciprocating movement of the connecting frame can be realized to cooperate with the cleaning felt to brush the inside of the measuring port back and forth to clean, thereby reducing the problem of dust adhesion and ensuring the accuracy of subsequent detection data.

[0016] The setting of the pressure-resistant frame, the positioning strip and the connecting block, that is, the pressure-resistant frame can be accurately installed to the outside of the current sensor housing body through the positioning docking effect of the positioning strip and the connecting block, to realize the composition of a pressure-resistant structure and reduce the probability of the housing being squeezed and changed in direction.

[0017] The setting of the blocking component, that is, the upper baffle and the side baffle are respectively installed on the upper end and the side of the pressure-resistant frame to form a double pressure-resistant structure to cooperate with the corresponding first spring, the first damper and the second spring and the second damper to perform efficient pressure-resistant buffering cooperation to ensure the stability of the shell.

[0018] When the locking blocks on both sides move to the two sides of the bottom of the fixed disk, with the help of the compression springs on both sides, the locking blocks on both sides can be automatically locked with the two sides of the bottom of the fixed disk to improve the tightness of the connection between the pressure-resistant frame and the external body of the current sensor housing and reduce the occurrence of loose connection problems. When the plug-in tube is pressed, the locking blocks on both sides can be synchronously moved downward to clamp and pull up the movable disk set at the lower end of the vertical rod to make the movable disk contact with the fixed disk.

[0019] The setting of the heat dissipation component, that is, the heat dissipation fans provided on both sides of the lower end of the shell, can assist in the wind discharge of the heat generated inside the shell, and cooperate with the heat dissipation holes provided on the front side of the shell to quickly discharge the heat, so as to avoid the excessive temperature inside the shell and the occurrence of spontaneous combustion, thereby achieving auxiliary heat dissipation and fire prevention. The setting of the drive box, transmission structure and cleaning structure, that is, when the driving wheel at the lower end of the box body is driven, it can cooperate with the external transmission belt to realize the synchronous rotation of the driven wheels on both sides. As the driven wheels on both sides rotate, the turntable docked at the front side can rotate accordingly, and cooperate with the connecting belt to make the auxiliary turntable rotate at the same time. Therefore, the docking block installed on the outside of the connecting belt can drive the rotating shaft along the moving trajectory of the circular tube, so that the rotating shaft can perform horizontal reciprocating movement of the docking plate connected to the outer end. In this way, the heat dissipation fan connected to the lower end of the docking plate through the support block will realize left and right reciprocating heat dissipation. Thermal assistance is used to enhance the heat dissipation range. At the same time, when the driving wheel rotates, the rotation of the first bevel gear connected to the front side can be realized, so that the first bevel gear can realize the rotation of the second, third and fourth bevel gears in turn. Therefore, the rotating rod connected to the middle part of the fourth bevel gear will rotate at the same time to drive the connecting frame that is sleeved on the outside and connected to the circulating groove opened on the outside through the pin shaft to move back and forth along the inside of the measuring port. Then, the cleaning felt installed on the outside of the connecting frame will brush the inside of the measuring port back and forth to clean it, reduce dust adhesion, and ensure the accuracy of subsequent measurement data.

[0026] Among them, the upper baffle plate 741 is arranged in a concave plate shape as a whole, and there is a spacing between the lower ends of the left and right sides of the upper baffle plate 741 and the side baffle plate 744, ensuring that the upper baffle plate 741 and the side baffle plate 744 can realize efficient wrapping protection of the outer side of the current sensor housing body 1, reducing the occurrence of the problem of blind angle protection; the locking block 756 is arranged in a right-angled trapezoidal block shape as a whole, and the locking block 756 is slidably built into the left and right sides of the lower end of the plug-in tube 752, that is, in conjunction with the outer inclined end of the locking block 756, the left and right lateral movement of the locking block 756 can be conveniently realized to meet the lateral locking or lateral unlocking; the fixed disk 757 and the movable disk 759 are both arranged in a smooth frustum, and the movable disk 759 can move up and down along the vertical rod 758 set in the middle of the fixed disk 757, so that the smooth locking and unlocking process can be flexibly realized through the offset or distance effect of the fixed disk 757 and the movable disk 759.

[0027] Specifically, in order to ensure that the current sensor has a certain pressure resistance effect during use and avoid deformation caused by external force, after completing the connection activity between the current sensor housing body 1 and the connecting plate 2, the pressure-resistant frame 71 can be set on the outside of the current sensor housing body 1. During the setting process, the positioning strips 72 set on the four sides of the inner side of the pressure-resistant frame 71 and the connecting blocks 73 set on both sides of the outer end of the current sensor housing body 1 are used to achieve the accurate sleeve installation of the pressure-resistant frame 71 and the current sensor housing body 1, so that the pressure-resistant frame 71 can realize the sleeve protection of the outer side of the current sensor housing body 1 and achieve a layer of pressure-resistant protection. At the same time, the resistance set on the outside of the pressure-resistant frame 71 is used to prevent the pressure sensor from being deformed. The baffle assembly 74 can realize the formation of a double pressure-resistant protection state, that is, the upper baffle plate 741 installed on the upper end of the pressure-resistant frame 71 can realize the pressure-resistant protection of the top through the buffer combination of the first spring 742 and the first damper 743, and the side baffle plates 744, the second spring 745 and the second damper 746 respectively arranged on the left and right sides of the pressure-resistant frame 71 can realize the pressure-resistant protection of the left and right sides of the current sensor housing body 1. Therefore, the double pressure-resistant protection state of the outer side of the current sensor housing body 1 can be realized by cooperating with the pressure-resistant frame 71 sleeve and the blocking effect of the upper baffle plate 741 and the side baffle plate 744 on each side, thereby improving the use stability of the current sensor housing body 1 and reducing the problem of extrusion deformation; Secondly, after the pressure-resistant frame 71 is sleeved onto the outside of the current sensor housing body 1, the bottom blocks 751 symmetrically mounted on the left and right sides of the lower end of the pressure-resistant frame 71 will abut against the left and right sides of the upper end of the base 3, and during the docking process, the plug-in tube 752 mounted inside the bottom block 751 will be plugged into the outside of the fixed disk 757 and move downward accordingly. During the downward movement, the locking blocks 756 laterally mounted on the left and right sides of the lower end of the plug-in tube 752 will cooperate with the external inclined surface to contact the smooth truncated cone-shaped fixed disk 757, that is, the lateral opposite movement of the locking blocks 756 on both sides is realized, and as the locking blocks 756 on both sides move in opposite directions, the connecting shafts 75 docked at the other ends of the locking blocks 756 on both sides are moved. 4, the compression spring 755 connected to the other side will be squeezed, so that when the lower end of the bottom block 751 contacts with the upper end of the base 3, the locking blocks 756 on both sides will release the contact and squeezing effect with the fixed disk 757, so that the compressed compression springs 755 on both sides will respectively realize the reset push of the connecting shaft 754 connected to the side, so that the locking blocks 756 on both sides move laterally relative to each other along the lower end of the plug-in tube 752, so that the locking blocks 756 on both sides will be synchronously snapped into the left and right sides of the lower end of the fixed disk 757 to achieve mutual locking and matching, ensuring that the pressure-resistant frame 71 is sleeved to the outside of the current sensor housing body 1, and can be in a stable state when performing pressure-resistant protection activities, thereby reducing the occurrence of loose docking problems; Secondly, when it is necessary to disassemble the pressure-resistant frame 71 and the current sensor housing body 1, it is only necessary to press the plug-in tube 752 plugged into the middle of the bottom block 751 to enable the plug-in tube 752 to simultaneously push down the locking blocks 756 on both sides of the interior. In this process, not only can the locking blocks 756 on both sides move downward synchronously, but also the tension springs 753 connected on both sides of the lower end can be stretched to prepare for subsequent resetting and realize elastic force preparation activities. When the locking blocks 756 on both sides move downward and contact the outside of the movable disk 759 movably installed at the lower end of the vertical rod 758, the locking blocks 756 on both sides will cooperate with the elastic force of the compression springs 755 corresponding to the side to press and support to realize the movable disk 759 are clamped against each other, so that when the plug-in tube 752 is loosened and the tension springs 753 on both sides are stretched to automatically pull up the plug-in tube 752, the movable plate 759 will be driven upward synchronously, so that the movable plate 759 will automatically move up to abut against the bottom of the fixed plate 757, thereby, the locking distance between the movable plate 759 and the fixed plate 757 will be automatically closed, so that the locking blocks 756 on both sides can smoothly pass through the outer sides of the movable plate 759 and the fixed plate 757 to achieve the outward unlocking activity, thereby, the locking effect of the left and right sides of the lower end of the pressure-resistant frame 71 and the current sensor housing body 1 can be quickly released, so as to quickly disassemble the pressure-resistant frame 71 as a whole.

During this process, the heat dissipation fans 765 installed on the left and right sides of the lower end of the connecting shell 761 will be opposite to the upper end of the current sensor housing body 1. At this time, by driving the heat dissipation fans 765 on both sides, the wind-driven heat generated by the internal electronic components can be discharged and dissipated when the current sensor performs detection activities, and the row of heat dissipation holes 762 opened on the front side of the connecting shell 761 can be used to achieve rapid heat discharge, thereby ensuring that the temperature of the electronic components inside the current sensor housing body 1 is in a stable state, avoiding the problem of spontaneous combustion due to excessive operating temperature of the electronic components, and thus achieving auxiliary fire protection coordination; In order to improve the heat dissipation range of the heat dissipation fans 765 on both sides, the servo motor 7633 arranged inside the box 7631 can be driven to make the servo motor 7633 realize the rotation of the driving wheel 7632 connected to the front side. As the driving wheel 7632 rotates, the transmission belt 7634 connected to the outside of the driving wheel 7632 will rotate accordingly, and realize the synchronous rotation and driving of the driven wheels 7635 connected to the upper sides. As a result, the main turntable 7641 connected to the front side of the driven wheels 7635 on both sides will rotate at the same time. As the main turntables 7641 on both sides rotate, the corresponding connecting belts 7642 connected to the outer ends of the main turntables 7641 on both sides can realize the synchronous rotation and driving of the auxiliary turntable 7643 connected to the other side. The docking blocks 7644 correspondingly installed at the outer ends of the connecting belts 7642 on both sides will drive the rotating shaft 7645 connected to the front side to reciprocate along the circular tube track with the connecting belt 7642, and as the rotating shaft 7645 moves, the docking plate 7646 connected to the rotating shaft 7645 through the vertical groove will cooperate with the supporting block 766 connected to the bottom to perform horizontal reciprocating movement, thereby, the heat dissipation fan 765 installed between the supporting blocks 766 on both sides can reciprocate left and right along the lower end of the connecting shell 761 to dissipate heat, greatly improving the heat dissipation range of the heat dissipation fan 765, ensuring the uniform external conduction and discharge of the internal heat of the current sensor housing body 1, and further enhancing the fire prevention effect of the current sensor housing body 1; Secondly, when the driving wheel 7632 rotates with the servo motor 7633, the first bevel gear 7671 connected to the front side of the driving wheel 7632 will rotate synchronously and realize the meshing transmission of the second bevel gear 7672 connected to the bottom, so that when the second bevel gear 7672 is driven to rotate, the third bevel gear 7673 installed at the lower end can be synchronously rotated, thereby, the fourth bevel gear 7674 meshed with the lower end of the third bevel gear 7673 can realize the rotation of the middle longitudinal docking rotating rod 7675. As the rotating rod 7675 rotates, the connecting frame 7677, which is sleeved on the outside of the rotating rod 7675 and connected to the circulating groove on the outside of the rotating rod 7675 through the pin 76710, will move back and forth along the inside of the measuring port 4. Therefore, the cleaning felt 7679 arranged on the outside of the connecting frame 7677 will move back and forth to assist in brushing and cleaning the inside of the measuring port 4, ensure the cleanliness of the inside of the measuring port 4, reduce the problem of dust adhesion, and ensure the accuracy of subsequent wire detection data. The above description is only a preferred example of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions recorded in the aforementioned embodiments, or to replace some of the technical features therein by equivalents.
