Description

Technical Field

[0001] The invention belongs to the technical field of power grids, and in particular relates to a safety monitoring system for power grids. Background Art

[0002] The power grid is a whole composed of substations and transmission and distribution lines of various voltages, called the power grid. Its main task is to transmit and distribute electric energy and change the voltage through transformers. The power grid includes three units: substation, transmission and distribution, which are responsible for the conversion, transmission and distribution of electric energy respectively. The transmission network is mainly responsible for sending the electricity generated by the power plant to the substation through the transmission line, and then collecting and distributing the same level voltage through the bus. The distribution network is responsible for distributing electricity to different voltage levels for users to use.

[0003] The monitoring equipment used in the safety monitoring system of the power grid is generally placed in a box. During the transportation of the box, due to the lack of fixing devices for the monitoring equipment, the box will be bumped and the monitoring equipment will shake. The monitoring equipment will then collide with the inner wall of the box. The electronic components on the monitoring equipment are easily damaged by the collision, resulting in the monitoring equipment being unable to continue to complete the monitoring work. Summary of the invention

[0004] The present invention aims to provide a safety monitoring system for a power grid to solve the above technical problems. Through the detachable setting of the limit device, the monitoring equipment can be effectively protected from damage during the transportation process without affecting the normal monitoring work of the monitoring equipment.

[0005] In order to solve the above technical problems, the present invention provides a safety monitoring system for a power grid, comprising a housing, a monitoring device and a limit device arranged inside the housing; wherein:

[0006] A first through hole is provided on the top of the shell; the movable end of the limiting device is inserted into the first through hole and abuts against the monitoring device; and the fixed end of the limiting device is detachably connected to the shell.

[0007] In the above scheme, the limiting device is inserted into the first through hole of the shell, and its movable end can be clamped on the monitoring equipment, which can limit the shaking of the monitoring equipment during transportation, avoid damage to electronic components on the monitoring equipment due to collision, and effectively protect the monitoring equipment from damage; and the limiting device is detachable, and the limiting device can be disassembled after the transportation is completed to ensure that it does not affect the normal monitoring work of the monitoring equipment.

[0008] Furthermore, the limiting device includes a limiting plate, a first baffle and a second baffle; wherein: the top of the first baffle and the top of the second baffle are respectively fixedly connected to the two ends of the limiting plate; the first baffle and the second baffle together serve as the movable end of the limiting device and are inserted into the first through hole, abutting against the monitoring device; the limiting plate serves as the fixed end of the limiting device and is detachably connected to the outer shell.

[0009] In the above scheme, the setting of the first baffle and the second baffle can realize the limitation of the two sides of the monitoring device. When the first baffle and the second baffle are inserted into the first through hole, the first baffle and the second baffle abut against the two sides of the monitoring device, which can firmly limit the position of the monitoring device.

[0010] It should be noted that, in order to facilitate the installation of the first baffle and the second baffle, two first through holes can be provided. And for the stability of the connection between the first baffle and the second baffle and the housing, the cross-section of the first baffle and the second baffle can be set to an "L" shape, and the two can be plugged into the housing to form a wrapped space, which can be respectively snapped onto the side edges of the monitoring device, and can effectively protect the corners of the monitoring device from collision.

[0011] Furthermore, the first baffle and the second baffle are both rubber structures.

[0012] In the above scheme, the first baffle and the second baffle are set as rubber structures. On the one hand, the contact between the baffle and the monitoring device can be more tight. On the other hand, the soft contact surface of the rubber structure can effectively prevent the baffle from causing damage to the monitoring device during transportation.

[0013] Furthermore, a first connecting piece is provided on the limit plate; a second connecting piece is provided on the outer shell; wherein: when the movable end of the limit device is inserted into the first through hole and abuts against the monitoring equipment, the limit plate is detachably connected to the second connecting piece through the first connecting piece.

[0014] In the above scheme, the first connecting member can be a bolt, and the corresponding second connecting member can be a screw. The first connecting member and the second connecting member are threadedly connected to fix the limit plate on the outer shell; the first connecting member can also be a slot, and the corresponding second connecting member can be a block. The first connecting member and the second connecting member are clamped to fix the limit plate on the outer shell.

[0015] Furthermore, the first connecting member includes a clamping hole; the second connecting member includes a clamping column, a support plate, a spring and a movable plate; wherein: a through hole is opened on the support plate, and the fixed end of the clamping column passes through the through hole and is fixedly connected to the movable plate; the spring is sleeved on the clamping column between the support plate and the movable plate; one end of the spring is fixedly connected to the support plate, and the other end is fixedly connected to the movable plate; when the movable end of the limiting device is inserted into the first through hole and abuts against the monitoring equipment, the movable end of the clamping column is clamped on the clamping hole, so that the limiting plate and the second connecting member are detachably connected.

[0016] In the above scheme, the limit plate and the second connecting member are detachably connected by connecting the clamp hole and the clamp column. The connection structure is simple, and the installation and removal of the limit device can be realized quickly and conveniently. The expansion and contraction characteristics of the spring are cleverly utilized in the second connecting member. When the movable plate drives the clamp column to move, the spring will be stretched to generate elastic potential energy. After the limit device is installed, only the movable plate needs to be loosened, and the clamp column can be inserted into the clamp hole under the tension of the spring. While the installation is convenient, the integrity of the second connecting member can also be ensured.

[0017] Furthermore, the first connecting member includes a plurality of clamping holes, and the second connecting member includes a plurality of clamping columns and a plurality of springs, the number of which is the same as the number of the clamping holes; wherein: a plurality of through holes are opened on the support plate, and the fixed ends of a plurality of the clamping columns pass through the corresponding through holes and are fixedly connected to the movable plate; a plurality of the springs are sleeved on the corresponding clamping columns between the support plate and the movable plate; one end of a plurality of the springs are fixedly connected to the support plate, and the other end is fixedly connected to the movable plate; when the movable end of the limiting device is inserted into the first through hole and abuts against the monitoring equipment, the movable ends of a plurality of the clamping columns are clamped on the corresponding plurality of the clamping holes, so that the limiting plate and the second connecting member are detachably connected.

[0018] In the above solution, the connection between the first connector and the second connector can be made more secure by the cooperation of the multiple clamping holes and the multiple clamping columns, effectively preventing the loose connection during transportation, which may cause the limiting device to be separated from the housing, thereby causing damage to the monitoring device. In addition, the overall connection structure is simple, and the installation and removal of the limiting device can be realized quickly and conveniently.

[0019] Furthermore, the outer shell includes a sealing door and a box body; wherein: the side of the sealing door is rotatably connected to the side of the box body; the monitoring device is arranged inside the box body; a first through hole is arranged on the top of the box body; the movable end of the limiting device is inserted into the first through hole and abuts against the monitoring device; the box body is detachably connected to the fixed end of the limiting device.

[0020] In the above solution, the sealing door can be rotated to tightly close the box body, so that the monitoring equipment forms a closed space to protect the monitoring equipment.

[0021] Furthermore, a second through hole is provided at the bottom of the box body at a position corresponding to the first through hole; the movable end of the limiting device is inserted into the first through hole, and when abutting against the monitoring device, the movable end of the limiting device is clamped in the second through hole.

[0022] In the above scheme, a second through hole corresponding to the corresponding position of the first through hole is set at the bottom of the box, which can further limit the movable end of the limiting device, so that the movable end of the limiting device has higher mechanical strength, and can more tightly support the monitoring equipment without shaking during the transportation of the monitoring equipment, thereby improving the protection effect of the monitoring equipment.

[0023] Furthermore, the safety monitoring system also includes a display device; the display device is fixedly arranged on the sealing door, and an input end of the display device is electrically connected to an output end of the monitoring device.

[0024] In the above scheme, the monitoring equipment can be used to conduct real-time safety monitoring of power grid equipment, and transmit the monitoring data to the display device, which displays the data for the convenience of staff to view. The display device is set on the sealed door to facilitate the real-time safety monitoring of power grid equipment by staff.

[0025] Furthermore, a plurality of heat dissipation holes are provided on the side of the box body, which can facilitate the heat dissipation of the monitoring device, thereby extending the service life of the monitoring device and preventing the monitoring device from being damaged due to overheating.

[0026] In the above scheme, when the monitoring device needs to be moved, the staff first pulls the movable plate backwards to stretch the spring, and the clamping column will move with the movable plate to avoid the moving path of the limit plate; at this time, the staff can insert the first baffle plate and the second baffle plate into the first through hole together, so that the first baffle plate and the second baffle plate can abut against the monitoring device to limit the monitoring device; then the staff loosens the movable plate and aligns the clamping column with the clamping hole. Under the tension of the spring rebound, the movable plate moves the clamping column, and the clamping column will be inserted into the clamping hole to fix the limit plate, thereby realizing the installation of the limit device. Similarly, the limit device can be detached from the housing.

[0027] In the above scheme, the limiting device can be easily installed and removed from the casing, and can well protect the monitoring equipment during transportation of the monitoring equipment, effectively avoiding the problem of damage to electronic components caused by collision between the monitoring equipment and the box during transportation.
