[0026] Example: Figures 1 to 6 As shown, a switch cabinet discharge detector comprises a discharge detector body 1 and a base 2, wherein a top plate 3 is arranged on the top of the discharge detector body 1, and four mounting seats 6 with openings facing downwards are detachably mounted at the bottom edge of the top plate 3, and a spiral spring is arranged inside the mounting seat 6, and four shading cloths 7 are arranged below the four mounting seats 6, and a ventilation hole 12 is formed on the adjacent side of two shading cloths 7, and an upper connecting portion 8 for connecting the upper end of the shading cloth 7 is arranged at the movable end of the spiral spring, and a lower connecting portion 11 for fixing the adjacent ends of the two shading cloths 7 is connected to the lower end of the shading cloth 7, and four supporting components 5 for ensuring the stability of the top plate 3 placed on the top of the base 2 are arranged at the bottom of the top plate 3, and a storage cavity 9 is opened on the front wall of the base 2;

[0027] Specifically, when the sun shines, the air holes 12 formed on the adjacent sides of the two shading cloths 7 can allow the heat on the outside of the discharge detector body 1 to be discharged outwards, and the cold air in the external environment can be blown into the space formed by the shading cloth 7 to block the dust on the discharge detector body 1, which can effectively avoid the problem that the heat on the outside of the discharge detector body 1 is difficult to diffuse outwards under the sun, thereby ensuring the service life of the discharge detector body 1. At the same time, under the action of the upper connecting part 8, it is convenient to assemble or disassemble and replace each shading cloth 7, which effectively reduces the economic loss compared to replacing the integrated protective shell cover; the lower connecting part 11 provided in addition can ensure the stability of the connection between the adjacent sides of the two shading cloths 7, avoid the shaking of the placement position of the shading cloth 7 due to external wind force, and ensure the effect of the shading cloth 7 to block the sunlight on the discharge detector body 1.

[0028] like Figure 3As shown, the upper connecting portion 8 includes an upper mounting block 801, an "L"-shaped upper mounting block 801 is connected to the movable end of the spiral spring, a placement cavity 802 penetrating the upper mounting block 801 is provided on one side of the upper mounting block 801, a horizontal tube with a square outside and a round inside is installed on the upper end of the shading cloth 7, a same hanging rod 803 is connected between the horizontal tube and the placement cavity 802, a fixing groove 804 for fixing the end of the hanging rod 803 is provided on one side of the upper mounting block 801, an anti-slip pattern is provided on the hand-grip end of the hanging rod 803, and the outer diameter value of the hand-grip end of the hanging rod 803 is 1.2 times the inner diameter value of the placement cavity 802;

[0029] Specifically, by passing the hanging rod 803 through the placement cavity 802 and the horizontal tube in sequence until the end of the hanging rod 803 can be inserted into the interior of the fixing groove 804, the shading cloth 7 can be hung between the front and rear upper mounting blocks 801. The structure is simple and easy to operate.

[0030] like Figure 4 As shown, the outer wall surface of the end of the hanging rod 803 is provided with an external thread, the inner wall surface of the fixing groove 804 is provided with an internal thread, and the end of the hanging rod 803 is threadedly connected with the fixing groove 804;

[0031] Specifically, the external thread and the internal thread can enhance the firmness of the connection between the end of the hanging rod 803 and the fixing groove 804, effectively preventing the end of the hanging rod 803 from accidentally slipping out of the fixing groove 804, thereby ensuring the stability of the shade cloth 7 when in use.

[0032] like Figure 5 As shown, the lower connecting portion 11 includes a lower positioning plate 1101, the lower end of the shading cloth 7 is connected with a solid lower positioning plate 1101, one end of the lower positioning plate 1101 is provided with a threaded hole 1102, the other end of the lower positioning plate 1101 is connected with a screw 1103 through a bearing, and a protective pad made of silicone material is bonded to the bottom of the lower positioning plate 1101;

[0033] Specifically, by providing a solid lower positioning plate 1101, the weight of the lower end of the shade cloth 7 can be increased to prevent the lower end of the shade cloth 7 from being retracted upward due to the action of the spiral spring of the base 2 when there is a lack of pulling force. In addition, by rotating the screw 1103 until its end can be threadedly connected to the inside of the threaded hole 1102, the lower ends of the adjacent sides of the two shade cloths 7 can be connected, thereby ensuring the stability of the shielding surface of the four shade cloths 7 to the discharge detector body 1.

[0034] like Figure 6As shown, the support assembly 5 includes a support column 501, a support column 501 is arranged below the top plate 3, the upper end of the support column 501 is connected to the bottom of the top plate 3 through a rotating shaft 507, a positioning column 503 is arranged at the lower end of the support column 501, a clamping cavity for accommodating the positioning column 503 is provided at the top of the base 2, a block 508 is connected to the upper end of the positioning column 503, a through hole is provided on the block 508, a plug-in board 505 is arranged inside the through hole, and two plug-in slots 506 for accommodating one end of the plug-in board 505 are provided on the inner wall surface of one side of the support column 501;

[0035] Specifically, the rotating shaft 507 can be set to drive the support column 501 to rotate under the action of gravity. When the support column 501 rotates ninety degrees and its lower end corresponds to the locking cavity, the plug-in board 505 can be pulled outward, so that one end of the plug-in board 505 can be taken out from the upper plug-in slot 506, and then the positioning column 503 can be plugged into the inside of the locking cavity under the action of gravity. Finally, the plug-in board 505 is pushed inward until one end of the plug-in board 505 can be plugged into the lower plug-in slot 506, which effectively ensures the stability of the positioning column 503 plugged into the inside of the locking cavity, and also enhances the firmness of the top plate 3 mounted on the top of the discharge detector body 1.

[0036] like Figure 6 As shown, two sliding grooves 502 are provided on the left and right inner wall surfaces of the lower end of the support column 501, and the two sides of the block 508 are connected to the sliding grooves 502 through the sliders 504;

[0037] Specifically, the sliding groove 502 and the slider 504 can enhance the stability of the downward sliding of the positioning column 503, and can also enhance the stability of the connection between the positioning column 503 and the support column 501, thereby ensuring the supporting effect of the positioning column 503 on the top plate 3.

[0038] When in use, the user can take out the required components from the storage cavity 9, then mount the top plate 3 on the top of the discharge detector body 1 (a pad is connected to the bottom of the top plate 3 to prevent wear on the top of the discharge detector body 1), and then pass the hanging rod 803 through the placement cavity 802 and the cross tube in sequence until the end of the hanging rod 803 can be inserted into the interior of the fixing groove 804. The provided external and internal threads can enhance the firmness of the connection between the end of the hanging rod 803 and the fixing groove 804, and effectively prevent the end of the hanging rod 803 from accidentally slipping out of the fixing groove 804, so that the shading cloth 7 can be hung between the front and rear upper mounting blocks 801.

[0039] At the same time, the rotating shaft 507 can drive the support column 501 to rotate under the action of gravity. When the support column 501 rotates ninety degrees and its lower end corresponds to the engaging cavity, the plug-in board 505 can be pulled outward, so that one end of the plug-in board 505 can be taken out from the upper plug-in slot 506. Then, under the action of gravity, the positioning column 503 can be plugged into the inside of the engaging cavity. Finally, the plug-in board 505 is pushed inward until one end of the plug-in board 505 can be plugged into the lower plug-in slot 506, which effectively ensures the stability of the positioning column 503 plugged into the inside of the engaging cavity. At the same time, it can also enhance the firmness of the top plate 3 mounted on the top of the discharge detector body 1.

[0040] At the same time, under the action of gravity of the lower positioning plate 1101, the shading cloth 7 can be driven to fall downward until the bottom surface of the lower positioning plate 1101 contacts the upper surface of the discharge detector body 1, and then the screw 1103 is rotated until its end can be threadedly connected to the inside of the threaded hole 1102, so that the lower ends of the two adjacent sides of the shading cloths 7 can be connected, ensuring the stability of the four shading surfaces of the discharge detector body 1 on the four sides of the four shading cloths 7. At the same time, when the shading cloths 7 block the sunlight for the discharge detector body 1, the heat on the outside of the discharge detector body 1 can be diffused outward from the air holes 12, effectively reducing the temperature around the discharge detector body 1, and at the same time, external cold air can also be blown in from the air holes 12, ensuring the service life of the discharge detector body 1.

[0041] When the device is not needed, just remove the top plate 3 from the top of the discharge detector body 1, then flip the top plate 3 one hundred and eighty degrees so that the support assembly 5 is rotated to the top of the top plate 3, and finally place the required components inside the storage cavity 9 for easy access without taking up storage space.

[0042] In summary: when the sun shines, the ventilation holes 12 formed on the adjacent sides of the two shading cloths 7 can allow the heat on the outside of the discharge detector body 1 to be discharged outwards, and the cold air in the external environment can be blown into the space formed by the shading cloth 7 to block the dust on the discharge detector body 1, which can effectively avoid the problem that the heat on the outside of the discharge detector body 1 is difficult to diffuse outwards under the sun, thereby ensuring the service life of the discharge detector body 1. At the same time, under the action of the upper connecting part 8, it is convenient to assemble or disassemble and replace each shading cloth 7, which effectively reduces the economic loss compared to replacing the integrated protective shell cover; the lower connecting part 11 provided in addition can ensure the stability of the connection between the adjacent sides of the two shading cloths 7, avoid the shaking of the placement position of the shading cloth 7 due to external wind force, and ensure the effect of the shading cloth 7 to block the sunlight on the discharge detector body 1.
