DETAILED DESCRIPTION

[0019] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0020] See also Figure 1-4 The utility model provides a technical solution: an emergency cut-off linkage detection device for an outdoor power distribution cabinet, comprising a box body 1, a placement groove 2 is provided at the lower end of the middle part of the inner cavity of the box body 1, a metal ball 3 is placed inside the placement groove 2, and evenly distributed arc grooves 5 are provided on the peripheral side of the inner cavity of the box body 1, and two symmetrically arranged first conductive sheets 51 are arranged inside each arc groove 5, and two through holes 22 are provided at the bottom of the box body 1 corresponding to the placement groove 2, and a sleeve 6 is provided at the bottom of the box body 1, and a hollow tube 7 that can be inserted into the through hole 22 is movably provided on the sleeve 6, and the hollow tube 7 is an H-shaped structure, and the upper and lower ends of the hollow tube 7 Each of the four contact magnets 71 is connected by a guide wire 72. The lower end of the inner cavity of the sleeve 6 is provided with a second conductive sheet 63 corresponding to the two contact magnets 71 on the lower side, and an alarm 8 is provided on the box body 1. When the distribution cabinet is subjected to a light impact, if the distribution cabinet is not tilted, or the tilt angle is very small, the metal ball 3 moves out of the placement groove 2 under the action of inertia and falls into the annular groove 4. At this time, the hollow tube 7 falls off the metal ball 3, the contact magnet 71 contacts the second conductive sheet 63, and the two second conductive sheets 63 are connected through the contact magnet 71 and the guide wire 72, and the alarm 8 sounds an alarm.

[0021] When the distribution cabinet is hit hard and tilted seriously, the metal ball 3 moves out of the placement groove 2 under the action of inertia and moves to a certain arc groove 5 through the annular groove 4. The positioning magnet 52 adsorbs and fixes the metal ball 3. The two first conductive plates 51 are connected under the action of the metal ball 3, and the emergency cut-off switch of the outdoor distribution cabinet works, thereby cutting off the power supply inside the outdoor distribution cabinet.

[0022] Furthermore, a positioning magnet 52 capable of attracting the metal ball 3 is provided inside the arc groove 5 , so as to position the metal ball 3 .

[0023] Furthermore, an annular groove 4 is provided at the lower end of the inner cavity of the box body 1 to prevent the metal ball 3 from rolling.

[0024] Furthermore, a guide plate 62 for preventing the hollow tube 7 from rotating is provided inside the sleeve 6 , and the guide plate 62 is located between two vertical tubes of the hollow tube 7 , thereby preventing the hollow tube 7 from rotating as a whole.

[0025] Furthermore, a third conductive sheet 9 is provided at the upper end of the inner cavity of the box body 1 corresponding to the two contact magnets 71 on the upper side. When there is a lot of water accumulation near the outdoor distribution cabinet, the accumulated water enters the sleeve 6 through the connecting hole 61, and the hollow tube 7 moves upward due to the buoyancy of the water and pushes the metal ball 3 away until the contact magnet 71 on the upper side of the hollow tube 7 contacts the third conductive sheet 9. At this time, it means that the water is too deep. After the two third conductive sheets 9 are connected through the contact magnet 71 and the guide wire 72, the emergency cut-off switch of the outdoor distribution cabinet is operated, thereby cutting off the internal power supply of the emergency cut-off switch of the outdoor distribution cabinet.

[0026] Furthermore, a connection hole 61 is opened at the lower end of the side of the sleeve 6 . When a large amount of water accumulates near the outdoor power distribution cabinet, the accumulated water enters the sleeve 6 through the connection hole 61 .

[0027] Furthermore, a magnet sheet 21 is provided in the placement groove 2 to position the metal ball 3 .

[0028] The alarm 8 used in the utility model is a commonly used electronic component in the prior art, and its working mode and circuit structure are well-known technologies and are not elaborated here. The alarm 8 is powered by a distribution cabinet, and the two connection terminals of the alarm 8 switch are respectively connected to the two second conductive plates 63. When the two second conductive plates 63 are connected through the contact magnet 71 and the guide wire 72, the alarm 8 sounds an alarm.

[0029] The contact end of the emergency cut-off switch of the outdoor power distribution cabinet is connected to the two first conductive plates 51 inside the arc groove 5 and the two third conductive plates 9 at the upper end of the box body 1. When the two first conductive plates 51 are connected or the two third conductive plates 9 are connected, the emergency cut-off switch of the outdoor power distribution cabinet can be operated, thereby cutting off the internal power supply of the outdoor power distribution cabinet.

[0030] When using:

[0031] The box body 1 is installed at the bottom of the outdoor power distribution cabinet, and the contact end of the emergency cut-off switch of the outdoor power distribution cabinet is connected to the two first conductive sheets 51 inside the arc groove 5 and the two third conductive sheets 9 at the upper end of the box body 1. When the two first conductive sheets 51 are connected or the two third conductive sheets 9 are connected, the emergency cut-off switch of the outdoor power distribution cabinet can be operated, thereby cutting off the internal power supply of the emergency cut-off switch of the outdoor power distribution cabinet;

[0032] When the power distribution cabinet is hit lightly, if the power distribution cabinet does not tilt or the tilt angle is very small, the metal ball 3 moves out of the placement groove 2 under the action of inertia and falls into the annular groove 4. At this time, the hollow tube 7 falls off the metal ball 3, the contact magnet 71 contacts the second conductive sheet 63, and the two second conductive sheets 63 are connected through the contact magnet 71 and the guide wire 72, and the alarm 8 sounds an alarm;

[0033] When the power distribution cabinet is hit hard and tilted seriously, the metal ball 3 moves out of the placement slot 2 under the action of inertia and moves to a certain arc slot 5 through the annular slot 4. The positioning magnet 52 adsorbs and fixes the metal ball 3. The two first conductive sheets 51 are connected under the action of the metal ball 3. The emergency cut-off switch of the outdoor power distribution cabinet works, thereby cutting off the internal power supply of the outdoor power distribution cabinet.

[0034] When there is a lot of water near the outdoor distribution cabinet, the water enters the sleeve 6 through the connecting hole 61, and the hollow tube 7 moves upward due to the buoyancy of the water and pushes the metal ball 3 away until the contact magnet 71 on the upper side of the hollow tube 7 contacts the third conductive sheet 9. This indicates that the water is too deep. After the two third conductive sheets 9 are connected through the contact magnet 71 and the guide wire 72, the emergency cut-off switch of the outdoor distribution cabinet is activated, thereby cutting off the internal power supply of the outdoor distribution cabinet.

[0035] The utility model can detect the impact of the outdoor distribution cabinet, and send out an alarm or cut off the power supply of the distribution cabinet in time according to the impact of the distribution cabinet, so as to avoid leakage, thereby avoiding harm to the surrounding environment and people, and can improve the safety of the use of the outdoor distribution cabinet and facilitate use.
