Description

Technical Field

[0001] The invention belongs to the technical field of electric power equipment, and in particular relates to a protective peripheral device of an electric energy metering device. Background Art

[0002] In the power system, electric energy metering devices play a vital role. They are responsible for accurately measuring and recording key data such as voltage, current, power, power generation, and user power consumption. These data are not only an important basis for economic settlement between power supply and demand parties, but also an important reference for power company operation and management. However, since electric energy metering devices are usually placed in outdoor environments and exposed to natural conditions for a long time, they face many challenges.

[0003] On the one hand, electric energy metering devices need to cope with adverse weather conditions, such as strong sunlight exposure and rain erosion. These environmental factors may damage the device and affect its measurement accuracy and service life. On the other hand, electric energy metering devices also need to guard against human damage and electricity theft. Although traditional electric energy metering device protection equipment can play a protective role to a certain extent, its door lock structure is often easy to pry open, resulting in theft or damage of the device, causing losses to users and power companies.

[0004] What is more serious is that when these protective devices are damaged, the energy metering devices are exposed, which can easily cause safety problems. For example, rainwater may cause short circuits or grounding of the internal circuits of the equipment, which not only poses a safety hazard to passers-by, but also may affect the stable operation of the power grid. In addition, the existing technology lacks timely and effective alarm devices, and cannot promptly detect and respond to the situation where the protective equipment is damaged.

[0005] Therefore, developing a new type of electric energy metering device protection peripheral device with higher protection performance, stronger anti-pry lock structure and real-time alarm function is of great significance for ensuring the safe operation of the electric energy metering device, maintaining the stability of the power system and the safety of users. Summary of the invention

[0006] In view of the above-mentioned deficiencies in the prior art, the present invention provides a protective peripheral device for an electric energy metering device to solve the above-mentioned technical problems.

[0007] The present invention provides a protective peripheral device for an electric energy metering device, comprising a box body, a locking mechanism, an alarm module, a control box and a power module for supplying power to the entire device;

[0008] The box body is provided with a box door, which is rotatably connected to the box body through a rotating shaft. A lock core mechanism is arranged on the side of the box door away from the rotating shaft. The locking mechanism is symmetrically arranged on the box door on the upper and lower sides of the lock core mechanism. A transmission rod is arranged between the locking mechanism and the lock core mechanism. The control box is arranged on the inner side of the box door, and the alarm module is communicatively connected with the control box.

[0009] A further improvement of the present technical solution is that the lock core mechanism includes a protective shell, and a lock core arranged through the center of the protective shell, a transmission gear is arranged on the periphery of the lock core, the lock core can drive the transmission gear to rotate, transmission racks are arranged on both sides of the transmission gear, the transmission racks are meshed with the transmission gears, the lower end of one of the transmission racks is connected to a transmission rod through a first connecting plate, and the upper end of the other transmission rack is connected to another transmission rod through a second connecting plate, and the transmission direction of the transmission rod is perpendicular to the axial direction of the lock core.

[0011] A further improvement of the technical solution is that one end of the gasket away from the moving block is connected to the control box through a wire.

[0012] A further improvement of the technical solution is that a wire tube is arranged on the outside of the wire.

[0013] A further improvement of the technical solution is that the control box includes a control box shell, a control module and a communication module are arranged in the control box shell, the alarm module and the power supply module are also arranged in the control box shell, the first end of the communication module and the first end of the alarm module are both connected to the control module, the second end of the communication module and the second end of the alarm module are both connected to one of the wires connected to the gasket, and the other wire connected to the gasket is connected to the power supply module.

[0014] A further improvement of the technical solution is that an antenna is also provided on the control box, and the antenna is connected to the control module via the communication module.

[0015] A further improvement of the technical solution is that it also includes a limit plate, which is sleeved on the transmission rod and one end of which is fixed on the box door.

[0016] The beneficial effects of the present invention are:

[0018] Secondly, the protective peripheral device is equipped with an enhanced locking mechanism, which is symmetrically arranged on the box door on the upper and lower sides of the lock core mechanism, and is linked to the lock core mechanism through a transmission rod. This design greatly improves the safety of the protective device, making traditional lock picking methods difficult to work, and effectively preventing human damage and electricity theft.

[0019] Furthermore, the device also integrates an alarm module, which is connected to the control box. Once the protective peripheral device is illegally damaged or opened, the alarm module will be activated immediately and emit a loud alarm to attract the attention of people around. At the same time, the alarm information can also be sent to the remote monitoring center through the control box, so that the power company can quickly grasp the situation and take corresponding measures.

[0020] Finally, the protective peripheral device is also equipped with a power module to provide a stable power supply for the entire device. This design ensures that the device can operate stably under continuous working conditions and also facilitates maintenance and repair work.

DETAILED DESCRIPTION

[0030] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.

[0031] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used in the specification of the present invention herein are only for the purpose of describing specific embodiments and are not intended to limit the present invention.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5As shown, the present invention provides a protective peripheral device for an electric energy metering device, including a box body 110, a locking mechanism 150, an alarm module 170, a control box, and a power module 180 for supplying power to the entire device; a box door 120 is arranged on the box body 110, and the box door 120 is rotatably connected to the box body 110 through a rotating shaft, a lock core mechanism 130 is arranged on the side of the box door 120 away from the rotating shaft, the locking mechanism 150 is symmetrically arranged on the box door 120 on the upper and lower sides of the lock core mechanism 130, a transmission rod 140 is arranged between the locking mechanism 150 and the lock core mechanism 130, the control box is arranged on the inner side of the box door 120, and the alarm module 170 is connected to the control box in communication. Among them, the box body 110 is made of waterproof and anti-corrosion material.

[0033] Specifically, the lock core mechanism 130 includes a protective shell 131, and a lock core 132 that passes through the center of the protective shell 131. A transmission gear 133 is arranged on the periphery of the lock core 132. The lock core 132 can drive the transmission gear 133 to rotate. Transmission racks 134 are arranged on both sides of the transmission gear 133. The transmission racks 134 are meshed with the transmission gear 133. The lower end of one of the transmission racks 134 is connected to a transmission rod 140 through a first connecting piece 135, and the upper end of the other transmission rack 134 is connected to another transmission rod 140 through a second connecting piece 136. The transmission direction of the transmission rod 140 is perpendicular to the axial direction of the lock core 132. After the key is inserted into the lock cylinder 132, the key is turned in one direction, and the transmission gear 133 drives the transmission rack 134 to move, thereby driving the transmission rod 140 to move linearly toward the upper and lower ends (away from the lock cylinder 132), and the end of the transmission rod 140 is inserted into the transmission rod 140 positioning hole on the box body 110 to achieve the locking function. When the lock needs to be unlocked, the key is turned in the opposite direction to drive the transmission rod 140 to move linearly in the direction close to the lock cylinder 132, and the end of the transmission rod 140 is pulled out from the transmission rod 140 positioning hole on the box body 110 to achieve the unlocking function.

[0034] The locking mechanism 150 includes a moving block 151, a gasket 153, a hollow insulating ring 154 and a reset spring 155. The top and bottom of the inner side of the box body 110 are both provided with a transmission rod positioning hole. A moving block mounting groove is provided on the side of the transmission rod positioning hole close to the box door 120. The moving block 151 is vertically installed in the moving block mounting groove (the moving block can move in the moving block mounting groove when subjected to force). The gasket 153 is installed on the box body 110 on the side of the moving block mounting groove away from the transmission rod positioning hole. The hollow insulating ring 154 is installed on the side of the gasket 153 close to the moving block 151. On the side, a return spring 155 is arranged between the moving block 151 and the hollow insulating ring 154, one end of the return spring 155 is fixed on the moving block 151, and the other end of the return spring 155 is fixed on the hollow insulating ring 154. A contact column 152 is arranged inside the return spring 155, and one end of the contact column 152 is fixed on the moving block 151. When the return spring 155 is in a normal state, the contact column 152 has no contact with the hollow coil. When the transmission rod 140 squeezes the return spring 155 through the moving block 151, the contact column 152 can be connected to the hollow insulating ring 154. The end of the gasket 153 away from the moving block is connected to the control box through a wire 156, and a wire tube 157 is arranged on the outside of the wire.

[0035] In addition, the control box includes a control box housing 161, in which a control module 162 and a communication module 163 are arranged, and an alarm module 170 and a power module 180 are also arranged in the control box housing 161, a first end of the communication module 163 and a first end of the alarm module 170 are both connected to the control module 162, a second end of the communication module 163 and a second end of the alarm module 170 are both connected to one of the wires connected to the gasket 153, and another wire connected to the gasket 153 is connected to the power module 180. At the same time, an antenna 164 is also arranged on the control box, and the antenna 164 is connected to the control module 162 through the communication module 163.

[0036] In addition, a limiting plate 190 is also included. The limiting plate 190 is sleeved on the transmission rod 140 , and one end of the limiting plate 190 is fixed on the box door 120 .

[0037] The working principle of the protective peripheral device is:

[0038] When the locking mechanism 150 is locked, there is a certain gap between the transmission rod 140 and the moving block 151 of the locking mechanism 150, and they will not touch each other. If the box door 120 is pulled by external force, that is, the box door 120 is pulled by external force and reaches a certain strength, the box door 120 drives the transmission rod 140 to move to the side of the moving block, and the transmission rod 140 pushes the moving block 151. When the moving block 151 moves, the reset spring 155 is compressed. After the reset spring 155 is compressed to a certain extent, the contact column 152 on the moving block 151 is connected to the gasket 153 through the hollow position of the hollow insulating ring 154 to form a loop. After the loop is formed, the signal is transmitted to the alarm module 170 of the control box, and then the alarm module 170 is triggered. The power amplifier plays a warning sound (to drive away illegal vandals), etc., so that the owner of the metering device can be informed to conduct on-site inspection and eliminate defects of the electric energy metering device in the protective peripheral device to prevent lawbreakers from stealing electricity or destroying the electric energy metering device.

[0039] Although the present invention has been described in detail by referring to the accompanying drawings and in combination with the preferred embodiments, the present invention is not limited thereto. Without departing from the spirit and essence of the present invention, a person skilled in the art may make various equivalent modifications or substitutions to the embodiments of the present invention, and these modifications or substitutions shall be within the scope of the present invention. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed by the present invention, and they shall be within the scope of protection of the present invention.
