Description

Technical Field

[0001] This invention relates to the technical field of monitoring equipment, and more particularly to a safety monitoring device used in switchgear. Background Technology

[0002] A switchgear is an electrical device mainly used in power systems for opening, closing, controlling, and protecting electrical equipment during power generation, transmission, distribution, and energy conversion. Safety monitoring devices used in switchgear refer to safety monitoring systems that can monitor maintenance personnel in real time to prevent accidents.

[0003] Currently, power plants and substations in power systems are equipped with varying numbers of high-voltage switchgear. Due to the long-term operation of the equipment, electrical circuit or mechanical failures are inevitable, requiring emergency repairs. When cleaning, maintenance, or other work is carried out inside the high-voltage switchgear, the high-voltage busbar and the stationary contacts on the busbar side are usually still energized, and the energized parts are only shielded by insulating baffles. After long-term use, the switchgear will deform, causing the baffles to malfunction and resulting in protection failure. This needs to be improved. Summary of the Invention

[0004] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the invention.

[0005] In view of the problem that existing safety monitoring devices used in switchgear can deform after long-term use, causing the baffles to malfunction and resulting in protection failure, this invention is proposed.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution: a monitoring component, including a base component, a connection component disposed on the base component, and an alarm component disposed on the connection component; an adjustment component, including a control component disposed on the connection component, a switching component disposed on the control component, and a lifting component disposed on the switching component; and an unlocking component, including a sliding component disposed on the control component, a limiting component disposed on the switching component, and an unlocking component disposed on the limiting component.

[0007] As a preferred embodiment of the safety monitoring device for switchgear described in this invention, the basic components include a switchgear body, a control unit disposed on the switchgear body, a cabinet door disposed on the switchgear body, and a support rod disposed inside the switchgear body.

[0008] As a preferred embodiment of the safety monitoring device for switchgear described in this invention, the connecting assembly includes a connector disposed inside the switchgear body, a connecting block disposed inside the connector, a fixing plate and an adjusting plate disposed on the connecting block, and a protective shell disposed on the fixing plate.

[0009] As a preferred embodiment of the safety monitoring device for switchgear described in this invention, the alarm component includes a buzzer alarm disposed inside the protective housing, a vent disposed outside the protective housing, and a signal transmitter and a signal receiver disposed on the outer wall of the protective housing.

[0010] As a preferred embodiment of the safety monitoring device for switchgear described in this invention, the control component includes a rotating component disposed inside the protective housing, a threaded rod disposed on the rotating component, and a lifting rod disposed on the threaded rod.

[0011] As a preferred embodiment of the safety monitoring device for switchgear described in this invention, the switching assembly includes an idle slot disposed inside the lifting rod and the threaded rod, a control slot disposed inside the idle slot, a control block disposed inside the idle slot, a connecting rod disposed on the control block, and a control column disposed on the connecting rod.

[0012] As a preferred embodiment of the safety monitoring device for switchgear described in this invention, the lifting assembly includes a spiral groove on the lifting rod, a lifting plate inside the protective shell, a connecting groove on the lifting plate, and a limiting point inside the connecting groove.

[0013] As a preferred embodiment of the safety monitoring device for switchgear described in this invention, the sliding assembly includes a sliding groove disposed inside the protective shell, a slider disposed inside the sliding groove, a through hole disposed inside the sliding groove, a connecting rod disposed on the slider, and a threaded groove disposed in the middle of the slider.

[0014] As a preferred embodiment of the safety monitoring device for switchgear described in this invention, the limiting component includes a storage slot disposed inside the control column, a limiting block disposed inside the storage slot, a limiting spring disposed on the limiting block, a limiting groove disposed on the rotating member, a square block disposed inside the rotating member, and a square slot disposed on the control column.

[0015] As a preferred embodiment of the safety monitoring device for switchgear described in this invention, the unlocking component includes a movable groove disposed inside the control column, a movable piece disposed inside the movable groove, a pressing rod disposed on the movable piece, and a diagonal rod disposed on the movable piece.

[0016] The beneficial effects of this invention are as follows: By bringing the magnet on the connector close to the switch cabinet body, the equipment is attracted to the inside of the switch cabinet. Pushing the control column upward causes the control column to drive the connecting rod upward, which in turn pushes the control block into the control slot. Then, controlling the rotating component causes the lifting rod to rotate, which in turn causes the spiral groove, in conjunction with the limiting point, to drive the lifting plate upward. This causes the signal transmitting and receiving ends to move upward, blocking the live parts in the sensing area. Next, controlling the pressing rod to move causes the inclined rod to pull the limiting block back, which then drives the control column downward, causing the limiting block to enter the lower limiting groove. Then, controlling the rotating component to rotate causes the threaded rod to rotate, driving the slider downward. This causes the connecting rod to push the adjusting plate to rotate, thus keeping the protective shell in a vertical position, allowing the equipment to operate normally. Furthermore, by operating the signal transmitting and receiving ends to block the live busbar, the signal is blocked if the maintenance personnel's arm exceeds the safe distance, preventing the receiving end from receiving the signal. This triggers an alarm to alert the maintenance personnel and prevent accidents. Attached Figure Description

[0028] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0031] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0032] Example 1, referring to Figures 1-10 The first embodiment of the present invention provides a safety monitoring device for switch cabinets. The device includes a monitoring component 100, including a base component 101, a connection component 102 disposed on the base component 101, and an alarm component 103 disposed on the connection component 102.

[0033] The basic component 101 is mainly used in the power generation, transmission, distribution and power conversion process of the power system to open, close, control and protect electrical equipment. The connecting component 102 is used to connect the monitoring device and the basic component 101, so that the monitoring device can detect in real time and the alarm component can be directly activated to remind on-site personnel when the safe distance is exceeded.

[0034] Preferably, the base component 101 and the monitoring device are connected together by the connecting component 102, so that the monitoring device covers the live bus inside. When the maintenance personnel's arm exceeds the installation distance, the alarm component 103 issues a warning to remind the on-site personnel and prevent accidents.

[0035] Furthermore, the adjustment component 200 includes a control component 201 disposed on the connection component 102, a switching component 202 disposed on the control component 201, and a lifting component 203 disposed on the switching component 202.

[0036] Among them, the control component 201 is used to control the operation of the lifting component 203, so that the lifting component 203 can rise and fall, driving the signal transmitting end 103c and the signal receiving end 103d to rise and fall, so that they block the live bus and prevent accidents. The switching component 202 is used to control the control component 201, so that the control component 201 switches from controlling the lifting component 203 to controlling the sliding component 301.

[0037] Preferably, by controlling the operation of the switching component 202, the control component 201 can switch back and forth between the lifting component 203 and the sliding component 301, controlling different parts and achieving different effects. The operation of the lifting component 203 drives the signal transmitter 103c and the signal receiver 103d to move up and down, so that the equipment can cover the live busbar on the rear side.

[0038] Furthermore, the unlocking component 300 includes a sliding component 301 disposed on the control component 201, a limiting component 302 disposed on the switching component 202, and an unlocking component 303 disposed on the limiting component 302.

[0039] The sliding component 301 is used to control the rotation of the adjusting plate 102d, so that the protective shell 102e is in a vertical state, which facilitates the connection between the signal transmitter 103c and the signal receiver. The limiting component 302 is used to limit the control component 201, so that the control component 201 is connected to the lifting component 203 or the sliding component 301 respectively. The unlocking component 303 is set to unlock the limiting component 302, which facilitates the operation of the switching component 202.

[0040] In summary: By operating the unlocking component 303, the switching component 202 drives the control component 201 to operate in conjunction with the lifting component 203 and the sliding component 301, respectively. This allows the control component 201 to move the signal transmitter 103c and the signal receiver 103d up and down via the lifting component 203, thereby covering the live busbar to prevent accidents. Then, by controlling the sliding component 301, the protective shell 102e is placed in a vertical position for easy docking.

[0041] Example 2, refer to Figures 1 to 8 The second embodiment of the present invention includes: a basic component 101 including a switch cabinet body 101a, a control unit 101b disposed on the switch cabinet body 101a, a cabinet door 101c disposed on the switch cabinet body 101a, and a support rod 101d disposed inside the switch cabinet body 101a.

[0042] The switchgear body 101a is used to protect the control unit 101b, thereby protecting the control unit 101b. The control unit 101b is used to open, close, control and protect electrical equipment during the power transmission, distribution and power conversion process in the power system. The support rod 101d is set to support the control unit 101b.

[0043] Furthermore, the connection assembly 102 includes a connector 102a disposed inside the switch cabinet body 101a, a connection block 102b disposed inside the connector 102a, a fixing plate 102c and an adjusting plate 102d disposed on the connection block 102b, and a protective shell 102e disposed on the fixing plate 102c.

[0044] The connector 102a is used to connect the connector block 102b on the protective shell 102e and the switch cabinet body 101a, so that the equipment can be installed outside the switch cabinet body 101a. The fixing plate 102c is used to connect the connector block 102b and the protective shell 102e together. The adjusting plate 102d is used to adjust the tilt of the protective shell 102e so that it is in a vertical state.

[0045] Preferably, by setting the connector 102a and the connecting block 102b, the fixing plate 102c and the protective shell 102e are fixed on the outside of the switch cabinet body 101a, thereby completing the installation. Then, by controlling the rotation amplitude of the adjusting plate 102d, the protective shell 102e is adjusted so that it is in a vertical state.

[0046] Furthermore, the alarm assembly 103 includes a buzzer alarm 103a disposed inside the protective housing 102e, a vent 103b disposed outside the protective housing 102e, and a signal transmitter 103c and a signal receiver 103d disposed on the outer wall of the protective housing 102e.

[0047] The buzzer alarm 103a is designed to emit an alarm sound to alert personnel on site that they have exceeded the safe distance. The vent 103b is designed to facilitate sound transmission. The signal transmitter 103c and the signal receiver 103d are designed for sensing and monitoring. When there are no obstructions, the equipment operates normally. When the signal at the transmitter is blocked, the buzzer will activate to alert personnel on site.

[0048] Preferably, by setting up a signal transmitter 103c and a signal receiver 103d, the monitoring area covers the area of ​​the live busbar. When maintenance personnel are cleaning or performing maintenance, if their arms exceed the safe distance, their arms will block the signal emitted by the signal transmitter 103c. When the receiver cannot receive the signal, the buzzer will sound an alarm to alert the personnel on site, thereby preventing the occurrence of danger.

[0049] Furthermore, the control assembly 201 includes a rotating member 201a disposed inside the protective housing 102e, a threaded rod 201b disposed on the rotating member 201a, and a lifting rod 201c disposed on the threaded rod 201b.

[0050] The rotating component 201a is designed to facilitate on-site personnel in controlling the extension and retraction of the equipment and adjusting its vertical position. The threaded rod 201b is designed to control the operation of the sliding component 301 to adjust the tilt of the equipment, thereby keeping it in a vertical position. The lifting rod 201c is designed to control the internal parts to rise and fall.

[0051] Preferably, the lifting rod 201c is rotated by the rotating component 201a, thereby causing the lifting rod 201c to move the internal lifting block upward, thus completing the adjustment of the equipment detection area and making the detection area cover the area where the live busbar exists.

[0052] Furthermore, the lifting assembly 203 includes a spiral groove 203a disposed on the lifting rod 201c, a lifting plate 203b disposed inside the protective shell 102e, a connecting groove 203c disposed on the lifting plate 203b, and a limiting point 203d disposed inside the connecting groove 203c.

[0053] The spiral groove 203a is used to control the movement of the limiting point 203d. The lifting plate 203b moves up and down in cooperation with the spiral groove 203a and the limiting point 203d. The connecting groove 203c is used to facilitate the lifting rod 201c to control the movement of the lifting plate 203b.

[0054] Preferably, by controlling the rotation of the rotating component 201a, the rotating component 201a drives the lifting rod 201c to rotate, thereby causing the spiral groove 203a to rotate. The rotation of the spiral groove 203a controls the movement of the limiting point 203d within it, thereby causing the limiting point 203d to move up and down, driving the lifting plate 203b to move, thereby causing the signal transmitting end 103c and the signal receiving end 103d to move together, thus achieving adjustment of the detection area.

[0055] In summary: By bringing the magnet on connector 102a close to the switch cabinet body 101a, the equipment is attracted to the inside of the switch cabinet. Pushing the control column 202e upwards causes the connecting rod 202d to move upwards, pushing the control block 202c into the control slot 202b. Then, controlling the rotating component 201a to rotate causes the lifting rod 201c to rotate, which in turn causes the spiral groove 203a, in conjunction with the limiting point 203d, to lift the lifting plate 203b upwards. This causes the signal transmitter 103c and signal receiver 103d to move upwards, blocking the live parts in the sensing area. Through the operation of the signal transmitter 103c and signal receiver 103d, the live busbar is blocked. If the maintenance personnel's arm exceeds the safe distance, the signal will be blocked, preventing the receiver from receiving the signal. This triggers the buzzer alarm 103a to sound an alarm, alerting the maintenance personnel and preventing accidents.

[0056] Example 3, referring to Figures 4 to 10 The third embodiment of the present invention includes: a switching assembly 202 comprising an idle slot 202a disposed inside the lifting rod 201c and the threaded rod 201b, a control slot 202b disposed inside the idle slot 202a, a control block 202c disposed inside the idle slot 202a, a connecting rod 202d disposed on the control block 202c, and a control column 202e disposed on the connecting rod 202d.

[0057] The idle slot 202a is used to place the control block 202c, so that the rotation of the control block 202c will not drive the lifting rod 201c and the threaded rod 201b to rotate. The control slot 202b is used to cooperate with the control block 202c. After the control block 202c enters the corresponding control slot 202b, it can drive the lifting rod 201c and the threaded rod 201b to rotate. The connecting rod 202d is used to connect the control column 202e and the control block 202c, so that the control column 202e can drive the control block 202c to rise and fall.

[0058] Preferably, by pushing the control column 202e, the connecting rod 202d causes the control block 202c to move upward and enter the control groove 202b on the lifting rod 201c, causing the lifting rod 201c to rotate, so that the rotating part 201a can drive the lifting rod 201c to rotate, and the lifting rod 201c controls the lifting plate 203b to move up and down.

[0059] Furthermore, the sliding assembly 301 includes a groove 301a disposed inside the protective shell 102e, a slider 301b disposed inside the groove 301a, a through hole 301c disposed inside the groove 301a, a connecting rod 301d disposed on the slider 301b, and a threaded groove 301e disposed in the middle of the slider 301b.

[0060] The slide groove 301a is used to limit the movement trajectory of the slider 301b, the through hole 301c is used to facilitate the connection of the connecting rod 301d to the slider 301b and the adjusting plate 102d, and the threaded groove 301e is used to facilitate the threaded rod 201b to control the slider 301b to move up and down.

[0061] Preferably, by pulling down, the control block 202c enters the control groove 202b inside the threaded rod 201b. The rotating component 201a is controlled to rotate, causing the threaded rod 201b to drive the slider 301b to move downward. During the downward movement of the slider 301b, the connecting rod 301d is controlled to move, causing the connecting rod 301d to push the adjusting plate 102d to rotate. This causes the adjusting plate 102d to control the protective shell 102e to rotate, thereby achieving the adjustment of the protective shell 102e.

[0062] Furthermore, the limiting component 302 includes a storage slot 302a disposed inside the control post 202e, a limiting block 302b disposed inside the storage slot 302a, a limiting spring 302c disposed on the limiting block 302b, a limiting groove 302d disposed on the rotating member 201a, a square block 302e disposed inside the rotating member 201a, and a square groove 302f disposed on the control post 202e.

[0063] The storage slot 302a is used to place the limiting block 302b, the limiting spring 302c is used to push the limiting block 302b so that the limiting block 302b is on the outermost side of the limiting spring 302c, and the square block 302e is used to cooperate with the square slot 302f to limit the movement trajectory of the control column 202e so that it can only move within a certain range.

[0064] Preferably, by pushing the control column 202e, the limiting block 302b enters the upper limiting groove 302d. At this time, the connecting rod 202d will push the control block 202c into the upper control groove 202b, so that the rotating part 201a can rotate and drive the lifting rod 201c to rotate. If the control column 202e is pulled into the lower limiting groove 302d, the threaded rod 201b will be driven to rotate, thereby adjusting the equipment.

[0065] Furthermore, the unlocking component 303 includes a moving groove 303a disposed inside the control column 202e, a moving piece 303b disposed inside the moving groove 303a, a pressing rod 303c disposed on the moving piece 303b, and a diagonal rod 303d disposed on the moving piece 303b.

[0066] The movable groove 303a is designed to facilitate the movement of the movable piece 303b inside, the pressing rod 303c is designed to facilitate the control of the movement of the movable piece 303b, and the inclined rod 303d is designed to drive the limiting block 302b to retract when the movable piece 303b moves upward, thereby causing the limiting block 302b to disengage from the limiting groove 302d, completing the unlocking, and thus facilitating the operation of the switching component 202.

[0067] Preferably, by pushing the squeezing rod 303c, the moving plate 303b drives the inclined rod 303d to operate, thereby causing the limiting block 302b to retract and disengage from the limiting groove 302d. Then, the control column 202e is pulled down or pushed up to operate the switching component 202, thereby controlling the rotating component 201a to drive different components to operate and complete the adjustment of the equipment.

[0068] In summary: By bringing the magnet on connector 102a close to switch cabinet body 101a, the equipment is attracted to the inside of the switch cabinet. Then, pushing control column 202e upwards causes connecting rod 202d to move upwards, pushing control block 202c into control slot 202b. Next, rotating component 201a rotates, causing lifting rod 201c to rotate, which in turn causes spiral groove 203a, in conjunction with limiting point 203d, to lift plate 203b upwards. This causes signal transmitter 103c and signal receiver 103d to move upwards, blocking the live parts in the sensing area. Finally, controlling the pressing rod 303c to move causes inclined rod 303d to pull limiting block 302b back. The control column 202e is then moved downwards, causing the limiting block 302b to enter the lower limiting groove 302d. The rotating component 201a is then controlled to rotate, causing the threaded rod 201b to rotate and move the slider 301b downwards. This causes the connecting rod 301d to push the adjusting plate 102d to rotate, thus placing the protective shell 102e in a vertical position, allowing the equipment to operate normally. Furthermore, through the operation of the signal transmitter 103c and signal receiver 103d, the energized busbar is blocked. If the maintenance personnel's arm exceeds the safe distance, the signal will be blocked, preventing the receiver from receiving the signal. This triggers the buzzer alarm 103a to sound an alarm, alerting the maintenance personnel and preventing accidents.
