Description

Technical Field

[0001] The present invention relates to the field of switch cabinet safety technology, and more specifically, to a valve mechanism locking system, method, device and medium. Background Art

[0002] The demand for improving the anti-error operation performance of switch cabinets comes from the anti-error demand generated in actual daily business. Compared with other high-voltage equipment, personnel in switch cabinets are closer to live equipment, and the live parts are more hidden because they are wrapped in protective compartments. Maintenance personnel cannot directly and effectively observe the distance between themselves and the live equipment. If the maintenance personnel forcibly open the valve equipment at this time, there is a risk of electric shock.

[0003] The existing methods to prevent personnel from operating the switch cabinet by mistake mainly rely on physical locking schemes and certain operating procedures to prevent personnel from missing operations.

[0004] In terms of equipment, in addition to mechanical padlocks and electric locks, the current mainly relies on live display devices to indicate the live information of the equipment. Generally, one live display device can only be used to indicate the live information of one side of the line side or bus side of the switch cabinet. When two live display devices are installed at the same time, one is generally installed on the front cabinet door and one on the rear cabinet door. When the equipment is being repaired, it is possible to miss the live status of one side of the equipment, which may lead to the possibility of an accident.

[0005] The traditional mechanical locking method is generally that when the trolley in the switch cabinet is pulled out, the valve mechanism is closed and the valve baffle blocks the static contact box, which improves the safety inside the switch cabinet and prevents maintenance personnel from electric shock. However, the valve mechanism lacks reliable locking, and the valve baffle is easy to open manually, resulting in the risk of electric shock to personnel or human damage to the static contact box, causing losses to personnel and equipment. Summary of the invention

[0023] Optionally, the controller is installed on the door of the secondary compartment of the cabinet through the opening, and is also used for:

[0024] Determine whether the cabinet is in maintenance status, and unlock the compartment valve according to whether the cabinet is energized.

[0047] Embodiment 1:

[0048] The present invention proposes a valve mechanism locking system, such as Figure 1 As shown, it includes: a valve locking mechanism, a detection mechanism and a controller;

[0049] The detection mechanism is used to detect the positions of the cabinet entry trolley and the cabinet entry staff, and send position signals of the cabinet entry trolley and the cabinet entry staff to the controller. The controller is used to receive the position signal and send a locking signal to the valve locking mechanism when the position signal reaches the cabinet locking condition. The valve locking mechanism is used to perform a locking operation on the valve connecting rod of the cabinet after receiving the locking signal, so that the valve of the cabinet is in a locked state.

[0050] Among them, it also includes: a confirmation switch and an indicator light;

[0051] The indicator light gives an indication when the valve of the cabinet is in a locked state;

[0052] The confirmation switch is used to unlock the valve door of the cabinet by pressing the confirmation switch when the valve door of the cabinet is in a locked state.

[0053] Wherein, the detection mechanism includes: a proximity switch;

[0054] The proximity switch is used to send out a metal plate position signal when the metal plate at the bottom of the cabinet entry trolley enters the detection range of the proximity switch. The metal plate position signal is the trolley position signal.

[0057] The staff position sensor is used to detect the position of the staff entering the locker and send out a position signal of the staff entering the locker.

[0058] Among them, the trolley position sensor is installed on the trolley running track in the trolley room of the cabinet. The cabinet-entering trolley can move on the trolley running track. The position of the cabinet-entering trolley is determined according to the trigger position of the cabinet-entering trolley and the valve connecting rod of the cabinet and the size of the cabinet-entering trolley.

[0059] The trolley position sensors are one group or multiple groups.

[0060] Wherein, the valve locking mechanism comprises: a motor lock;

[0061] The motor lock performs a locking operation on the valve locking mechanism.

[0062] Among them, it also includes: a switch cabinet door locking device, the switch cabinet door locking device is connected to the isolation baffle of the cabinet body;

[0063] The entry trolley can move on the trolley running track installed in the trolley chamber of the cabinet body. When the contact point of the transmission mechanism on the trolley running track is squeezed by the entry trolley, the switch cabinet valve door locking device rotates with the fixed axis as the center of the circle, so that the isolation baffle moves to the upper and lower sides, so that the isolation baffle is automatically closed as the entry trolley enters or exits, and the static contact of the isolation baffle is blocked.

[0064] The controller is installed on the door of the secondary compartment of the cabinet through an opening, and is also used for:

[0065] Determine whether the cabinet is in maintenance status, and unlock the compartment valve according to whether the cabinet is energized. When the position sensor of the entry trolley detects that the entry trolley has entered the trolley room of the cabinet, determine whether the current switch cabinet is in operation status. If so, immediately unlock the valve locking mechanism and release the lock of the switch cabinet valve locking device.

[0066] The cabinet further includes a micro camera installed in the trolley room of the cabinet to record the operation inside the cabinet and output the recorded data to the outside.

[0067] The present invention is further described below with reference to specific cases:

[0068] The objects of the present invention are:

[0069] (1) To lock the switch cabinet valve mechanism;

[0070] (2) After the switch cabinet trolley is pulled out, the valve mechanism is locked. After the trolley is pushed into the cabinet, the valve mechanism is unlocked through manual confirmation to prevent electric shock hazards inside the switch cabinet and human damage to the static contact box of the switch cabinet;

[0071] (3) Improve the intelligence level of switchgear equipment, monitor the energized state and trolley state of switchgear equipment, and intelligently control the opening and closing of switchgear compartment valves;

[0072] (4) Improve the intrinsic safety performance of the switch cabinet to prevent accidents of electric shock caused by the manual opening of live valves of the equipment during partial maintenance of the switch cabinet. Alarms can be issued for abnormal situations and video recording can be performed.

[0073] In order to achieve the above-mentioned purpose, the present invention provides a valve mechanism locking system, when the trolley is pulled out of the trolley chamber of the cabinet, the valve mechanism is locked, and the valve baffle cannot be opened at this time, so as to prevent dangerous situations after people enter the trolley chamber of the cabinet; when the trolley is pushed into the trolley chamber of the cabinet and locked, before the trolley is cranked in to close the switch, confirmation is performed by pressing the confirmation switch of the switch cabinet door, at which time the valve mechanism is unlocked, and the next step can be executed, and the handle is used to operate the trolley to realize the closing operation.

[0074] The valve mechanism locking system consists of the following parts: valve locking mechanism, trolley detection mechanism, valve locking controller and confirmation switch and indicator light. Figure 1 shown.

[0075] 1) Valve locking mechanism:

[0076] The opening and closing of the two valve baffles of the mobile switch cabinet valve mechanism are controlled by the connecting rod mechanism on both sides, and the purpose of locking the valve mechanism is achieved by locking the valve connecting rod. The motor lock is used to lock the valve baffle connecting rod.

[0077] like Figure 2 and 3 As shown, when the valve baffle opens and closes, the valve baffle will move up and down, and the valve baffle connecting rod will also move with it. The motor lock tongue blocks the valve baffle connecting rod, restricting the movement of the connecting rod to achieve the purpose of locking the valve mechanism.

[0078] 2) Trolley detection mechanism, such as Figure 4 As shown:

[0079] The trolley detection is performed through two proximity switches installed on the track at the bottom of the trolley room of the switch cabinet. Since the bottom of the trolley is a metal plate, the proximity switch mainly detects metal objects. The proximity switch is connected to the controller through a wire. When the trolley approaches the proximity switch, the proximity switch senses and transmits a signal to the controller.

[0080] Proximity switch detection trolley locking logic:

[0081] Valve mechanism locked:

[0082] Two proximity switches are installed front and back. When the trolley is pushed into the trolley chamber of the cabinet and is in the closed state, the valve baffle is opened and the valve lock is in the unlocked state. At this time, the rear proximity switch can detect the trolley;

[0083] When the trolley is pulled out, it moves from the rear proximity switch to the front proximity switch. When the trolley is in the unlocked and locked state, the front proximity switch can detect the trolley. At this time, the valve baffle is in the closed state. After the trolley is completely pulled out of the cabinet trolley room, the two proximity switches cannot detect the trolley. At this time, the controller will receive the signal from the proximity switch and think that the trolley has left the cabinet trolley room and needs to lock the valve mechanism. At this time, the motor lock tongue extends to block the valve baffle connecting rod to achieve the locking of the valve mechanism. Figure 5 shown.

[0084] 3) Valve locking controller, such as Figure 6 As shown:

[0085] The valve locking controller is installed in the control room of the switch cabinet, and is connected to the motor lock and the proximity switch through wires. It receives the signal from the proximity switch and sends a signal to the motor lock to control the motor lock.

[0086] 4) Confirm the switch and indicator light:

[0087] The confirmation switch and indicator light are installed on the door of the switch cabinet control room. The main function of the confirmation switch is: when the trolley is pushed into the cabinet and the trolley room is in the locked state, after confirmation, manually press the button to confirm, then the valve locking mechanism is unlocked and the valve mechanism is in the unlocked state;

[0088] The confirmation switch is also used to prevent the situation where someone enters the trolley room after the trolley is pulled out of the trolley room and accidentally senses the proximity switch, thereby unlocking the valve mechanism. The proximity switch must be sensed and then the confirmation switch must be pressed to unlock the valve mechanism. The indicator light mainly indicates the locked state of the valve.

[0089] Working principle and technical effect of valve locking system: The existing valve baffle installed in the cabinet door is purely mechanical. As the trolley is pushed in or pulled out, the valve baffle opens or closes. When the staff is repairing, they may accidentally open the valve baffle, posing a threat to the maintenance workers.

[0090] The present invention realizes anti-mistaken locking of the cabinet body, prevents maintenance personnel from opening the valve baffle due to mistakenly touching the switch or the connecting rod structure, and realizes operation safety.

[0091] When the trolley needs to be pushed into the cabinet to achieve the closing operation: at this time, the movable baffle is in a closed state under the restriction of the valve mechanism and cannot be forced to open. Push the trolley in, the trolley contacts the front sensor and the rear sensor in turn, and the trolley stops at the position of the rear sensor. The information of the two sensors is transmitted to the controller. The staff needs to click the confirmation switch for further closing operation. At this time, the valve mechanism motor rotates to release the restriction on the valve baffle. The trolley continues to push in to open the valve baffle through the connecting rod mechanism, and pushes in to achieve closing.

[0092] When the trolley needs to be pushed out of the cabinet to realize the opening operation (maintenance operation): the trolley withdraws and passes through the rear sensor and the front sensor in sequence. The trolley does not stop the linkage mechanism during the withdrawal process, and the valve baffle closes again under the action of gravity. The trolley completely withdraws from the cabinet, and the two sensors feed back data to the controller, which controls the valve mechanism to lock the valve baffle.

[0093] It should be noted that the sensor can only detect metal. If a person touches the two sensors with a metal rod and then clicks the confirmation switch, the movable baffle can still be opened.

[0094] The purpose of this solution is to prevent maintenance personnel from accidentally opening the movable baffle during maintenance and causing personal injury, rather than to prevent people from intentionally opening the movable baffle.

[0095] Comprehensive processing host, such as Figure 7 As shown:

[0096] The opening of the comprehensive processing host is installed on the secondary compartment door of the switch cabinet. It has equipment interfaces such as equipment power sensor interface, human position sensor interface, trolley position sensor interface, camera interface, etc. It collects equipment power status and trolley position status through wired connection. Its connection with each component equipment is as follows:

[0097] The host collects signals through the above sensors, and after comprehensive processing of relevant information, it can monitor the equipment operating environment in real time and make behavioral judgments. By controlling the externally connected valve locking device and cabinet door electromagnetic lock and other equipment, the switch cabinet can be made more intelligent and safer. The equipment anti-error status corresponding to the main operating conditions of the switch cabinet is shown in Table 1 below:

[0098] Table 1

[0099]

[0100] The host can also have the conventional functions of the live display device, which can realize the live indication of the switch cabinet, device self-test, anti-error device interface and other functions. By cooperating with the external anti-error device, the switch cabinet can be tested for electricity before routine operation to ensure the integrity of its business process.

[0101] If necessary, the host can also send abnormal signals remotely through the built-in wireless module, so that relevant personnel who are not on site can understand the situation on site.

[0102] Car position sensor:

[0103] In order to prevent the normal use of the trolley from being affected, we use the trolley position sensor to determine whether the trolley has entered. The trolley position sensor is installed in the trolley room of the switch cabinet and arranged on the trolley running track. According to the trigger position of the trolley and the switch cabinet compartment valve locking connecting rod and the size of the trolley, the trolley position sensor can be one group or multiple groups, which are used to detect the trolley in place signal and the trolley not in place signal.

[0104] When the trolley is not in place, the integrated processing host should determine that the current equipment is in maintenance status, and unlock the compartment valve according to whether the equipment is energized. When the trolley position sensor detects the entry of the trolley, the integrated processing host should determine that the current switch cabinet will enter the operating state, and immediately unlock the valve locking device to release the lock on the compartment valve to prevent affecting the normal operation of the equipment.

[0105] Personnel location sensor:

[0106] To prevent the trolley position sensor from being affected and causing misjudgment of the current working condition of the switch cabinet, we use a personnel position sensor to determine whether someone is currently entering. Generally speaking, the trolley cannot enter the switch compartment at the same time as the personnel, so when the personnel position sensor detects that someone has entered the switch cabinet, it should be determined that the equipment is currently in maintenance working state. If the equipment is energized, the compartment valve cannot be opened. If the equipment is not energized, the compartment valve can be opened. The opening of the compartment valve is directly related to whether the equipment is energized.

[0107] Switch cabinet door locking device:

[0108] The isolation baffle in the trolley-type switch cabinet is opened and closed through the transmission mechanism. During the trolley maintenance process, the isolation baffle is in a closed state. When the trolley is pushed into the cabinet, the contact point on the transmission mechanism at the guide rail is squeezed, and the mechanism rotates with the fixed axis as the center of the circle, thereby forcing the isolation baffle to move up and down. At this time, the moving contact can combine with the static contact to conduct the circuit. During the maintenance of the trolley-type switch cabinet, the trolley needs to be pulled out, and the isolation baffle automatically closes as the trolley is withdrawn, covering the static contact. Figure 8 As shown:

[0109] Design a valve locking device, pre-installed on the transmission rod of the isolation baffle. During the switch cabinet maintenance process, the trolley is not in place. At this time, if the static contact is energized, the comprehensive processing host sends a locking signal to the valve locking device. The valve locking device restricts the movement of the transmission rod of the isolation baffle to achieve the locking action of the switch cabinet valve. If the static contact is not energized, the comprehensive processing host sends an unlocking signal to the valve locking device, and the maintenance personnel can safely open the compartment valve for maintenance work. After installing this locking device, if Fig. 9 As shown, when the equipment is energized, a non-handcart cannot push the contact point of the transmission mechanism, thereby avoiding abnormal opening of the isolation baffle and avoiding accidents.

[0110] Camera:

[0111] The camera is installed in the switch cabinet trolley room and uses a miniature camera. When a switch cabinet is in maintenance (the trolley is not in the switch cabinet) and the switch cabinet is energized, a person enters the switch cabinet trolley room for maintenance work. The integrated processing host makes a voice broadcast to remind the current person that the equipment is energized, and starts the power of the camera in the cabinet to record the current person's operation in the switch cabinet. The camera content can be transmitted to the external system for real-time synchronous playback.

[0112] The invention realizes the locking function of the valve mechanism of the switch cabinet; the valve mechanism is locked by pulling the trolley out of the trolley chamber of the switch cabinet; after the trolley is pushed into the trolley chamber and locked, the valve mechanism is unlocked by confirming the switch.

[0113] The present invention realizes the locking of the switch cabinet valve mechanism, which can avoid the electric shock risk of maintenance personnel when performing maintenance in the trolley room, and can also avoid the occurrence of situations such as artificial damage to the static contact box of the switch cabinet.

[0114] The locking function of the switch cabinet valve mechanism is realized; the trolley is pulled out of the switch cabinet body trolley chamber to realize the locking of the valve mechanism; after the trolley is pushed into the trolley chamber and locked, the current equipment status of the switch cabinet can be comprehensively processed through the power detection sensor, trolley position sensor and personnel position sensor to intelligently judge whether the current personnel and equipment are in a safe state and intelligently unlock the switch cabinet valve.

[0115] If the maintenance personnel are in a dangerous environment, the device can intelligently lock the switch cabinet door to prevent accidents such as accidental touch, and simultaneously perform voice broadcasts and camera and video recording.

[0120] Step 3: After receiving the locking signal through the valve locking mechanism, a locking operation is performed on the valve connecting rod of the cabinet to put the valve of the cabinet in a locked state.
