[0027] The embodiments of the technical solutions of the present application will be described in detail below with reference to the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solutions of the present application, and therefore only serve as examples, and cannot limit the protection scope of the present application.

[0028] At present, the top of the drawer type switch cabinet is usually provided with an opening hole, which exposes the drawer type switch cabinet and causes external foreign matters such as rats and insects to enter the drawer type switch cabinet, especially when the temperature of the drawer type switch cabinet is higher than the ambient temperature in winter.

[0029] The foreign matters entering the drawer type switch cabinet can easily cause short circuit, sparking, tripping and other faults of the electrical equipment in the drawer type switch cabinet when the worker pushes the switch, which affects the normal work of the drawer type switch cabinet and reduces the working reliability of the drawer type switch cabinet.

[0030] In order to solve the above technical problems, the present application provides a drawer type switch cabinet protection device. The drawer type switch cabinet protection device provided by the embodiments of the present application will be described in detail below with reference to the accompanying drawings.

[0031] Please refer to Figure 1 The drawer type switch cabinet protection device 200 provided by the present application is applied to the drawer type switch cabinet 100, the top plate 110 of the drawer type switch cabinet 100 is provided with an opening hole 120, and the protection device 200 comprises a cover plate 210, a telescopic mechanism 220, a flexible tube 230, a sensor 240 and a controller. The cover plate 210 is located on the upper side of the opening hole 120; the outer contour of the cover plate 210 is larger than the hole diameter of the opening hole 120; one end of the telescopic assembly of the telescopic mechanism 220 is connected with the cover plate 210, and the other end is connected with the top plate 110; the flexible tube 230 is arranged between the cover plate 210 and the top plate 110 and is buckled in the opening hole 120; the side wall of the flexible tube 230 is provided with a plurality of through holes; the sensor 240 is used for detecting whether there is a target object around the top plate 110; and the controller is electrically connected with the telescopic mechanism 220 and the sensor 240.

[0032] The flexible pipe 230 of the cover hole 120 is arranged on the top plate 110 of the drawer type switch cabinet 100, and a through hole is arranged on the flexible pipe 230. When the sensor 240 detects that there is a target object around the top plate 110, the flexible pipe 230 can be driven to contract by the telescopic mechanism 220, the actual aperture size of the through hole is reduced, the target object is prevented from entering the inside of the drawer type switch cabinet 100, and the short circuit, sparking, tripping and other faults of the electrical equipment in the drawer type switch cabinet 100 caused by foreign matters when the staff pushes the switch are avoided. Therefore, the drawer type switch cabinet 100 can effectively avoid the influence of foreign matters on the normal work, and the working reliability of the drawer type switch cabinet 100 is improved.

[0033] The following will be described in combination with Figure 1 The specific structure of the drawer type switch cabinet protection device 200 will be introduced.

[0034] The cover plate 210 is located on the upper side of the hole 120; the outer contour of the cover plate 210 is larger than the aperture of the hole 120. The cover plate 210 can be circular, elliptical or quadrilateral, and the shape of the cover plate 210 is consistent with the shape of the hole 120. For example, when the hole 120 is quadrilateral, the cover plate 210 is also quadrilateral, and when the hole 120 is circular or elliptical, the cover plate 210 is also circular or elliptical. It should be noted that no matter what shape the hole 120 is, when the cover plate 210 is buckled on the hole 120, the hole 120 can be completely covered.

[0035] One end of the telescopic mechanism 220 is connected with the cover plate 210, and the other end is connected with the top plate 110. The telescopic mechanism 220 can be any one of a hydraulic cylinder, an air cylinder, an electric push rod, a ball screw mechanism and a gear and rack mechanism. As shown in Figure 1 The telescopic mechanism 220 can adopt an electric push rod, at this time, the cylinder body of the electric push rod can be installed on the cover plate 210, and the piston at the end of the piston rod of the electric push rod can be connected with the top plate 110. By controlling the piston rod to extend or retract along the direction indicated by the arrow in Figure 1 , the linear reciprocating motion of the telescopic mechanism 220 can be realized.

[0036] The flexible pipe 230 is arranged between the cover plate 210 and the top plate 110 and buckled in the opening 120; the side wall of the flexible pipe 230 is provided with a plurality of through holes; wherein the flexible pipe 230 can adopt a bellows, such as a metal bellows, a plastic bellows, etc., wherein the plastic bellows can be made of high-density polyethylene (HDPE) or polypropylene (PP). The maximum size of the through hole on the flexible pipe 230 can be 25mm-55mm, such as 25mm, 35mm, 45mm, 55mm, etc. The size of the through hole is consistent with the size of the opening 120 on the top plate 110, and the shape of the through hole can be a triangular hole, a quadrilateral hole, a circular hole, an elliptical hole, etc., and the designer can flexibly select the size and shape of the through hole according to actual needs. The telescopic mechanism 220 can support the flexible pipe 230 on the one hand and drive the flexible pipe 230 to elongate or shorten on the other hand. When the flexible pipe 230 is elongated, the actual aperture of the through hole approaches its maximum size; when the flexible pipe 230 is shortened, the actual aperture of the through hole becomes smaller and smaller.

[0037] The sensor 240 is used to detect whether there is a target around the top plate 110; the sensor 240 can be at least one of a vibration sensor, an infrared sensor, a camera, a laser radar. That is, the sensor 240 can only adopt one of a vibration sensor, an infrared sensor, a camera, a laser radar, or can adopt a combination of a plurality of them. The vibration sensor can determine whether there is a target around the top plate 110 by detecting whether the vibration around the opening 120 is greater than a set value. The camera can determine whether there is a target around the top plate 110 by comparing the collected image data with the historical image. The infrared sensor can determine whether there is a target around the top plate 110 by the infrared intensity emitted by the object. The laser radar can determine whether there is a target around the top plate 110 by emitting a detection signal to the target and comparing the received signal reflected from the target with the emitted signal. Of course, the sensor 240 can also adopt a Hall sensor and other various sensors, which will not be described herein.

[0038] The controller is electrically connected with the telescopic mechanism 220 and the sensor 240. When the sensor 240 detects that there is a target around the top plate 110, a trigger signal is sent to the controller, and the controller can control the telescopic mechanism 220 to contract according to the received trigger signal, thereby driving the flexible pipe 230 to shorten and reducing the actual aperture of the through hole, so as to avoid the target entering the inside of the drawer-type switchgear 100.

[0039] In order to ensure that the cover plate 210 is tightly attracted to the magnetic attraction piece 250 when it is driven by the telescopic mechanism 220 to move to the surface of the cover plate 210, in some embodiments of the present application, a magnetic attraction piece 250 can also be arranged on the top plate 110 to attract the cover plate 210 by magnetic attraction. Specifically, referring to Figure 1The magnetic attraction member 250 is arranged on the top plate 110 of the drawer-type switch cabinet 100 corresponding to the cover plate 210, and the cover plate 210 is made of a metal plate. In this way, when the cover plate 210 is moved to the surface of the cover plate 210 driven by the telescopic mechanism 220, the cover plate 210 is attracted to the magnetic attraction member 250.

[0040] It should be noted that the shape of the magnetic attraction member 250 can be in a whole form or in a split form. When the magnetic attraction member 250 is in the whole form, the magnetic attraction member 250 is in the form of a ring that matches the edge of the cover plate 210. When the magnetic attraction member 250 is in the split form, the number of the magnetic attraction member 250 can be multiple, and the multiple magnetic attraction members 250 are uniformly distributed about the edge of the cover plate 210. For example, when the cover plate 210 is in the quadrilateral form, three magnetic attraction members 250 can be used, and one magnetic attraction member 250 is arranged on the top plate 110 corresponding to each edge of the cover plate 210. The multiple magnetic attraction members 250 in the split form are more material-saving than the magnetic attraction member 250 in the whole form.
