Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, and more specifically, to a prefabricated substation anti-theft early warning device. Background Technology

[0002] A prefabricated box-type substation is a compact, factory-prefabricated indoor / outdoor power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines transformer voltage reduction and low-voltage power distribution functions, all housed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. It is particularly suitable for urban power grid construction and renovation, and represents a new type of substation that has emerged after traditional civil engineering substations. Since box-type substations contain various high-value electrical components, some criminals may attempt to steal them, necessitating anti-theft warnings.

[0003] In the existing technology, alarms are usually installed on prefabricated substations to provide early warning of theft. However, if criminals damage the alarms or fail to trigger them, timely warnings cannot be provided, which can lead to economic losses. Utility Model Content

[0004] The purpose of this invention is to solve the problem of criminals damaging alarms and causing them to fail to sound an alarm. A box-type substation anti-theft early warning device has been designed.

[0005] To achieve the above objectives, the technical solution of this utility model is a prefabricated substation anti-theft early warning device, comprising a protective enclosure, which is installed above the door panel inside the prefabricated substation. An alarm is installed inside the protective enclosure, as are a battery pack, a start button, and a control switch. The alarm, battery pack, start button, and control switch are electrically connected within the protective enclosure. A starter is installed on the protective enclosure. When the door panel of the prefabricated substation is opened, the alarm can be activated and sounded via the starter and start button.

[0006] Furthermore, the button end of the start button points downwards, the protective housing has an opening, and the lower end of the starter extends through the opening to the bottom of the protective housing.

[0007] Furthermore, the starter includes a lifting plate located below the start button. The lifting plate and the lower surface of the protective enclosure are connected by a telescopic spring. The lifting plate has a guide hole, and a guide rod is provided in the guide hole. The lower end of the guide rod is connected to the lower surface of the protective enclosure. An L-shaped limiting plate is installed on the lower surface of the lifting plate. The lower end of the L-shaped limiting plate extends through the clearance opening to the bottom of the protective enclosure. When the door of the prefabricated substation is closed, the door can intercept the lower end of the L-shaped limiting plate.

[0008] Furthermore, a limiting hole is opened on one side of the lower end of the L-shaped limiting plate, and a limiting rod is provided in the limiting hole. A spring pin is installed on the lower surface of the protective box, and the telescopic end of the spring pin is connected to the limiting rod. A push rod is installed on the telescopic end of the spring pin. When the door of the box-type substation is closed, the door can push the push rod to the rear and cause the limiting rod to move out of the limiting hole.

[0009] Furthermore, the alarm is wirelessly connected to a warning light, which is installed in the guard room.

[0010] The beneficial effects of this utility model are as follows: by installing the early warning device inside the box-type substation, criminals cannot damage the alarm. When criminals open the door, the alarm can be triggered by the starter, which will then sound and alert the staff that criminals are coming to steal, thereby enabling the staff to conduct patrols and reduce economic losses.

Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model.

[0013] In the description of this utility model, it should be understood that the terms "length," "width," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the accompanying drawings and are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, in the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0014] This utility model provides, for example Figure 1-4 The illustrated anti-theft alarm device for a prefabricated substation includes a protective enclosure 1, which is installed above the door panel inside the prefabricated substation. An alarm 2, a battery pack 3, a start button 4, and a control switch 5 are installed inside the protective enclosure 1. The alarm 2, battery pack 3, start button 4, and control switch 5 are electrically connected inside the protective enclosure 1. An actuator 6 is installed on the protective enclosure 1. When the door panel of the prefabricated substation is opened, the alarm 2 can be activated and an audible sound can be emitted through the actuator 6 and the start button 4.

[0015] The anti-theft warning process of the electrical components of this device is as follows: The alarm 2, battery pack 3, start button 4, and control switch 5 are all installed inside the protective enclosure 1. When the box-type substation is being repaired or operated, the staff will turn off the control switch 5. At this time, the battery pack 3 will not provide power to the alarm 2, and the alarm 2 will not sound. After the repair is completed, the control switch 5 will be turned on, and the circuit will be connected. However, the start button 4 will not be pressed, and the alarm 2 will not sound. When criminals come to steal electrical equipment, they must first open the door. After the door is opened, the start button 4 can be pressed through the starter 6, which will cause the alarm 2 to sound, thus providing an early warning.

[0016] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4 The start button 4 is pointed downwards, and the protective housing 1 has an opening 7. The lower end of the starter 6 passes through the opening 7 and extends to the bottom of the protective housing 1, so that the start button 4 can be pressed from the outside of the protective housing 1.

[0017] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4The starter 6 includes a lifting plate 8 located below the start button 4. The lifting plate 8 and the lower inner surface of the protective box 1 are connected by a telescopic spring 9. The lifting plate 8 has a guide hole 10 and a guide rod 11 is provided in the guide hole 10. The lower end of the guide rod 11 is connected to the lower inner surface of the protective box 1. An L-shaped limit plate 12 is installed on the lower surface of the lifting plate 8. The lower end of the L-shaped limit plate 12 extends through the clearance opening 7 to the bottom of the protective box 1. When the door of the box-type substation is closed, the door can intercept the lower end of the L-shaped limit plate 12.

[0018] The process of the starter 6 pressing the start button 4 is as follows: Under normal circumstances, when the door is closed, the upper end of the door can intercept the lower end of the L-shaped limit plate 12. At this time, the telescopic spring 9 is in a compressed state, and the lifting plate 8 cannot contact the start button. After the door is opened, under the elastic force of the telescopic spring 9, the lifting plate 8 and the L-shaped limit plate 12 can be pushed upward. The guide hole 10 and the guide rod 11 can ensure the movement direction of the lifting plate 8 and the L-shaped limit plate 12. After the lifting plate 8 moves upward, the start button 4 can be pressed, and the alarm 2 will sound.

[0019] Refer to the instruction manual appendix Figure 1 Instruction manual attached Figure 2 Instruction manual attached Figure 3 Included with instruction manual Figure 4 Before closing the door panel, pull the L-shaped limit plate 12 downwards, so that the limit hole 13 moves to the front of the limit rod 14. Then, under the elastic force of the spring pin 15, the limit rod 14 can extend into the limit hole 13, thereby blocking the L-shaped limit plate 12 and preventing the lifting plate 8 and the L-shaped limit plate 12 from pressing the start button 4. Then, the staff closes the door panel. The door panel can first contact the push rod 16, and then push the push rod 16, the telescopic end of the spring pin 15, and the limit rod 14 backwards, so that the limit rod 14 can move out of the limit hole 13. At this time, the limit rod 14 does not limit the L-shaped limit plate 12. Under the elastic force of the telescopic spring 9, the L-shaped limit plate 12 can be pushed upwards, and then blocked by the door panel, thereby preventing the L-shaped limit plate 12 from continuing to move upwards and pressing the start button 4, thus preventing the alarm 2 from being triggered.

[0020] Refer to the instruction manual appendix Figure 1 The alarm 2 is connected to the warning light 17 via a wireless signal. The warning light 17 is installed in the guard room. When the alarm 2 is triggered, the warning light 17 in the guard room can be activated via a wireless signal, which can help to remind the staff.
