Description

Technical Field

[0001] The present invention relates to the field of knife-switch monitoring, and particularly to a knife-switch status monitoring device. Background Art

[0002] A knife-switch is a type of manual switch for electrical equipment, also known as a blade switch, generally used for low-voltage electricity, and is divided into single-phase and three-phase knife-switches. There are various specifications according to different applications, and generally voltage and current are marked, such as 220 V, 16 A, which means it is applicable to a voltage of 220 V and the current does not exceed 16 amperes. Generally, it consists of a porcelain base, a plastic cover, and copper parts. The upper part is the inlet, the lower part is the outlet, and a fuse installation part is designed in the middle.

[0003] The existing knife-switch monitoring technology usually designs a monitoring circuit to monitor the knife-switch, but cannot effectively detect the external status of the knife-switch, that is, it cannot effectively observe the opening and closing status of the knife-switch externally. Moreover, the existing hardware with video monitoring functions is generally fixedly set. Even if its angle can be adjusted, since the connection parts of each contact inside the knife-switch are generally not directly on the surface, the video monitoring device cannot flexibly adjust the viewing angle to comprehensively monitor the knife-switch. Therefore, a knife-switch status monitoring device is proposed. Summary of the Invention

[0004] The purpose of the present invention is to provide a knife-switch status monitoring device, which solves the problems that the existing knife-switch status cannot directly monitor the actual opening and closing of the knife-switch, and the existing monitoring devices are difficult to flexibly adjust to achieve comprehensive monitoring.

[0005] To achieve the above purpose, the present invention provides the following technical solution: A knife-switch status monitoring device includes a slide rail. Guide blocks are slidably arranged at both ends of the slide rail, and a connecting plate and a cylinder are sequentially fixedly connected through the guide blocks. A bidirectional electric cylinder is connected between the connecting plates on both sides. An installation plate is installed on one side of the cylinder. A disk is slidably sleeved in each cylinder. The front end face of the disk is sequentially fixedly connected with an installation seat and a monitoring camera, and the rear end face is fixedly connected with a limiting rod. A plurality of springs are fixedly connected in an array between the front and rear side faces of the disk and the front and rear inner walls of the cylinder. A servo motor is installed on the installation plate, and a turntable is installed at the output end of the servo motor. An electric slide rail is fixedly installed along the radial direction of the turntable, and a slider is slidably arranged on the electric slide rail. A rotating plate is rotatably sleeved on the slider, and the other end of the rotating plate is sleeved on the surface of the limiting rod.

[0006] Preferably, a chamfered opening is provided at the front end of each cylinder, and the chamfered opening is annular and made of rubber material.

[0007] Preferably, both the front and rear ends of the cylinder are provided with through holes. The mounting seat and the monitoring camera extend to the front outer side of the cylinder, and the limiting rod extends to the rear outer side of the cylinder.

[0008] Preferably, positioning holes are also arranged in an array on the disc. Positioning rods are fixedly connected in an array between the front and rear inner walls of the cylinder and are sleeved in cooperation with the positioning holes. The diameter of the positioning holes is more than [X] times the diameter of the positioning rods. The length of the rotating plate is equal to the distance between the centers of the cylinder and the turntable.

[0009] Preferably, the springs on the front and rear sides of the disc are respectively arranged in a circumferential array around the mounting seat and the limiting rod.

[0010] Preferably, the electric slide rail is arranged in the diameter direction of the turntable and centered on the center of the turntable.

[0011] Preferably, a pin shaft is arranged at the rear end of the slider. Round holes are opened at both ends of the rotating plate. One end of the rotating plate is sleeved with the pin shaft through the round hole and is rotatably connected to the slider, and the other end is also rotatably sleeved with the extending end of the limiting rod through the round hole.

[0012] Preferably, an integrated detection cable module is arranged in the mounting seat.

[0013] Compared with the related art, a switch state monitoring device provided by the present invention has the following beneficial effects:

[0014] The present invention provides a switch state monitoring device. Guide blocks are slidably arranged at both ends of the slide rail, and a connecting plate and a cylinder are sequentially fixedly connected through the guide blocks. A two-way electric cylinder is fixedly connected between the two connecting plates on both sides. Thus, the distance between the two cylinders on both sides can be adjusted through the two-way electric cylinder.

[0015] The present invention provides a switch state monitoring device. The cylinder is designed to be through in the front and rear. A disc is slidably sleeved in the cylinder. Mounting seats, a monitoring camera and a limiting rod are respectively fixedly installed on the front and rear sides of the disc and extend to the front and rear outer sides of the cylinder. A plurality of springs are arranged in an array on the front and rear sides of the disc and are respectively fixedly connected to the front and rear inner walls of the cylinder. The disc can rotate within a certain range in the cylinder under the action of the springs, and the position of the front monitoring camera can be changed within a certain range, so that more shooting angles and orientations can be obtained, and it is convenient to comprehensively monitor the switch blade.

[0016] The present invention provides a knife-switch state monitoring device. A servo motor is installed on a mounting plate on a cylinder, and a turntable is installed through the servo motor. An electric slide rail is installed along the radial direction of the turntable, and a slider is slidably arranged on the electric slide rail. A rotating plate is sleeved between the slider and the extending end of the limiting rod at the rear side of the cylinder. Thus, the position of the slider can be adjusted through the electric slide rail. When the slider is at the center of the turntable, the other end of the rotating plate is also at the center of the cylinder at this time, so that the disc will not be driven to deflect. When the slider is not at the center of the turntable, under the rotation of the turntable, the slider will pull the rotating plate to rotate, and the other end of the turntable will also drive the limiting rod to deflect, thereby driving the disc to deflect in the cylinder, so as to adjust the shooting position of the monitoring camera. At the same time, the adjustment amplitude can be changed differently according to the distance between the slider and the center of the turntable.

[0017] This device has the characteristics of being convenient to adjust, enabling intuitive visual monitoring of the opening and closing of the knife-switch, having flexible adjustability of the monitoring angle, and comprehensive monitoring. BRIEF DESCRIPTION OF THE DRAWINGS

A bidirectional electric cylinder 5 is connected between the two connecting plates 3. An installation plate 7 is installed on one side of the cylinder 4. A disc 8 is slidably sleeved in each cylinder 4. A mounting seat 10 and a monitoring camera 11 are sequentially fixedly connected to the front end face of the disc 8, and a limiting rod 9 is fixedly connected to the rear end face. A plurality of springs 12 are fixedly connected in an array between the front and rear inner walls of the cylinder 4 and the front and rear side faces of the disc 8. A servo motor 13 is installed on the installation plate 7, and a turntable 14 is installed at the output end of the servo motor 13. An electric slide rail 15 is fixedly installed along the radial direction of the turntable 14, and a slider 16 is slidably arranged on the electric slide rail 15. A rotating plate 18 is rotatably sleeved on the slider 16, and the other end of the rotating plate 18 is sleeved on the surface of the limiting rod 9.

[0027] A chamfered opening 6 is provided at the front end of each cylinder 4, and the chamfered opening 6 is annular and made of rubber material.

[0028] Both the front and rear ends of the cylinder 4 are provided in a penetrating manner. The mounting seat 10 and the monitoring camera 11 extend to the front outer side of the cylinder 4, and the limiting rod 9 extends to the rear outer side of the cylinder 4.

[0029] Positioning holes 801 are also arrayed on the disc 8. Positioning rods 802 are fixedly connected in an array between the front and rear inner walls of the cylinder 4 and are sleeved in cooperation with the positioning holes 801. The diameter of the positioning holes 801 is more than 3 times the diameter of the positioning rods 802. The length of the rotating plate 18 is equal to the distance between the center of the cylinder 4 and the turntable 14.

[0030] The springs 12 on the front and rear side faces of the disc 8 are respectively arranged in a circumferential array around the mounting seat 10 and the limiting rod 9.

[0031] The electric slide rail 15 is arranged in the diameter direction of the turntable 14 and centered on the center of the turntable 14.

[0032] A pin shaft 17 is arranged at the rear end of the slider 16. Circular holes 181 are opened at both ends of the rotating plate 18. One end of the rotating plate 18 is sleeved with the pin shaft 17 through the circular hole 181 and is rotatably connected to the slider 16, and the other end is also rotatably sleeved with the extended end of the limiting rod 9 through the circular hole 181.

[0033] An integrated detection cable module is provided inside the mounting base 10.

[0034] Embodiment 1: A knife switch status monitoring device includes a slide rail 1. Guide blocks 2 are slidably arranged at both ends of the slide rail 1, and a connecting plate 3 and a cylinder 4 are sequentially fixedly connected through the guide blocks 2. A bidirectional electric cylinder 5 is connected between the connecting plates 3 on both sides. An installation plate 7 is installed on one side of the cylinder 4, so that the distance between the connecting plates 3 and the cylinder 4 on both sides can be adjusted by the bidirectional electric cylinder 5.

[0035] A disc 8 is slidably sleeved in each cylinder 4. The front end face of the disc 8 is sequentially fixedly connected with a mounting base 10 and a monitoring camera 11, and the rear end face is fixedly connected with a limiting rod 9. The front and rear ends of the cylinder 4 are both provided in a penetrating manner. The mounting base 10 and the monitoring camera 11 extend outside the front of the cylinder 4, and the limiting rod 9 extends outside the rear of the cylinder 4. Thus, under the adjustment of the bidirectional electric cylinder 5, the distance between the monitoring cameras 11 on the front side of the cylinder 4 can also be adjusted, so that the distance between the monitoring cameras 11 on the left and right sides can be adjusted in cooperation as needed, and different observation perspectives can be obtained.

[0036] A plurality of springs 12 are fixedly connected in an array between the front and rear side faces of the disc 8 and the front and rear inner walls of the cylinder 4. A servo motor 13 is installed on the installation plate 7, and a turntable 14 is installed at the output end of the servo motor 13. An electric slide rail 15 is fixedly installed along the radial direction of the turntable 14, and a slider 16 is slidably arranged on the electric slide rail 15. A rotating plate 18 is rotatably sleeved on the slider 16, and the other end of the rotating plate 18 is sleeved on the surface of the limiting rod 9. So that the disc 8 can deflect and turn to a certain extent inside the cylinder 4 under the action of the springs 12. When the disc 8 deflects and turns, that is, when the axis of the disc 8 deflects to form an angle with the axis of the cylinder 4, it can drive the monitoring camera 11 on the front side to rotate, so that the shooting position of the monitoring camera 11 can be adjusted, and further the shooting range can be adjusted, realizing video detection of different positions of the knife switch.

[0037] A chamfered opening 6 is provided at the front end of each cylinder 4, and the chamfered opening 6 is annular and made of rubber material. In this way, when the monitoring camera 11 deflects and is about to contact the opening at the front end of the cylinder 4, effective buffering can be carried out through the chamfered opening 6, avoiding damage to the monitoring camera 11.

[0038] The disc 8 is also provided with positioning holes 801 in an array. Positioning rods 802 are fixedly connected in an array between the front and rear inner walls of the cylinder 4 and are sleeved in cooperation with the positioning holes 801. When the disc 8 deflects in the cylinder 4, the positioning holes 801 and the positioning rods 802 can be sleeved in cooperation but not in contact, so that the disc 8 can be limited to a certain extent to prevent it from rotating due to deflection.

[0039] The diameter of the positioning hole 801 is more than 3 times the diameter of the positioning rod 802. The length of the rotating plate 18 is equal to the distance between the centers of the cylinder 4 and the turntable 14. The springs 12 on the front and rear sides of the disc 8 are respectively arranged in a circumferential array around the mounting seat 10 and the limiting rod 9. The electric slide rail 15 is arranged in the diameter direction of the turntable 14 and is centered on the center of the turntable 14. A pin shaft 17 is arranged at the rear end of the slider 16. Circular holes 181 are opened at both ends of the rotating plate 18. One end of the rotating plate 18 is sleeved with the pin shaft 17 through the circular hole 181 and is rotatably connected to the slider 16, and the other end is also rotatably sleeved with the extended end of the limiting rod 9 through the circular hole 181.

[0040] In the specific operation, the deflection of the disc 8 in the cylinder 4 can be carried out by pulling the extended end of the limiting rod 9 sleeved by the rotating plate 18 at the rear side of the cylinder 4. And since the other end of the rotating plate 18 is rotatably connected to the slider 16 through the pin shaft 17, and the slider 16 is on the turntable 14, the other end of the rotating plate 18 can be rotated by driving the turntable 14 to rotate by the servo motor 13, and then drive the limiting rod 9 and the disc 8 to deflect away from its axis in the cylinder 4.

[0041] The turntable 8 is installed with an electric slide rail 15 along its radial direction, and a slider 16 is slidably arranged on the electric slide rail 15. A rotating plate 18 is sleeved between the slider 16 and the extended end of the limiting rod 9 at the rear side of the cylinder 4. Therefore, the position of the slider 16 can be adjusted through the electric slide rail 15. When it is at the center of the turntable 14, the other end of the rotating plate is also at the center of the cylinder 4 at this time, so that the disc 14 will not be driven to deflect. When the slider is not at the center of the turntable 14, under the rotation of the turntable 14, the slider will pull the rotating plate 18 to rotate, and the other end of the turntable 18 will also drive the limiting rod 9 to deflect, and drive the disc 8 to deflect in the cylinder 4, thereby adjusting the shooting position of the monitoring camera 11. At the same time, the adjustment amplitude can be changed differently by the distance between the slider 16 and the center of the turntable.

[0042] Since an integrated detection cable module can be arranged in the mounting seat, it can detect the internal circuit of the knife switch by using the existing YOLO-V7 detection algorithm.
