Description

Technical Field

[0001] The present invention relates to the technical field of transformer substation protection equipment, and in particular to a safety auxiliary warning device. Background Art

[0002] A large number of cabinets are usually installed in the protection room of the substation for equipment placement and protection. In order to distinguish the cabinets during secondary equipment debugging and prevent operators from accidentally touching the equipment during operation, warning devices are usually set for equipment that does not need to be operated. Currently, the commonly used warning devices mostly use magnetic retractable safety warning belts or movable column-type retractable isolation belts. The above warning belts or isolation belts require independent supporting equipment. For work sites with a large number of cabinets, a wide working area, and relatively scattered work sites, the weight of the warning belt will lead to poor magnetic stability, and the retractable isolation belt will cause labor costs during frequent handling due to the heavy chassis, which will reduce the efficiency of equipment debugging.

[0003] Therefore, how to provide an efficient and lightweight warning device for protecting the screen cabinets in the room to improve the efficiency of the debugging process is a technical problem that needs to be urgently solved by technical personnel in this field. Summary of the invention

[0004] In view of this, an object of the present invention is to provide a safety auxiliary warning device to reduce the difficulty of setting up and improve the efficiency of debugging equipment in the protection room.

[0005] To achieve the above object, the present invention provides the following technical solutions:

[0006] A safety auxiliary warning device, comprising:

[0007] A transmitting part and a receiving part, wherein the transmitting part is used to transmit a laser signal to the receiving part, and the path of the laser signal passes through the cabinet door of the protective screen cabinet in the open state, and the cabinet door can block or deflect the laser signal;

[0008] The controller is electrically connected to the transmitting part and the receiving part, and the controller adjusts the transmitting part and / or the receiving part to send out a warning signal when the transmitting part is disconnected from the receiving part.

[0009] Preferably, in the above-mentioned safety auxiliary warning device, the transmitting part and the receiving part are both fixedly arranged on the protection screen cabinet.

[0010] Preferably, in the above-mentioned safety auxiliary warning device, both the transmitting part and the receiving part are provided with a magnetic back cover, and are fixed to the protective screen cabinet by means of a magnetic connection.

[0011] Preferably, in the above-mentioned safety auxiliary warning device, the transmitting part and the receiving part are arranged at the same horizontal height on the protection screen cabinet.

[0012] Preferably, in the above-mentioned safety auxiliary warning device, a single transmitting part is capable of transmitting two beams of laser signals having an angle, and the two receiving parts respectively receive one beam of the laser signal, and when any one of the receiving parts is disconnected from the transmitting part, the controller adjusts the transmitting part and / or the receiving part to send a warning signal.

[0013] Preferably, in the above safety auxiliary warning device, a speaker or a buzzer is provided on the transmitting part, and the warning signal is a sound signal.

[0014] Preferably, in the above safety auxiliary warning device, a warning light is further provided on the transmitting part, and the warning signal is a red or yellow flashing signal of the warning light.

[0015] Preferably, in the above-mentioned safety auxiliary warning device, the transmitting part includes a power supply, a switch and a laser transmitter. After the switch is turned on, the power supply supplies power to the laser transmitter and emits the laser signal.

[0016] Preferably, in the above-mentioned safety auxiliary warning device, the transmitting part and the receiving part are respectively supported by two supporting legs of equal height, and the transmitting part and the receiving part are close to the protection screen cabinet and spaced apart from the protection screen cabinet.

Specifically, the path of the laser signal between the transmitting part and the receiving part passes through the cabinet door of the protection screen cabinet in the open state, so that when the cabinet door is opened, the cabinet door cuts off or deflects the laser signal, causing the laser signal to be disconnected; correspondingly, the controller sends a warning signal when the laser signal is disconnected to feedback the operator to deal with the cabinet door that was opened by mistake in a timely manner. The above structure only needs to set the transmitting part and the receiving part to realize the auxiliary warning function. Compared with the current magnetic retractable safety warning belt or movable column retractable isolation belt, the transmitting part and the receiving part do not need to be supported by load bearing, only need a simple position setting, and can be used at any time, thereby reducing the risk of failure.

[0024] The core of the present invention is to disclose a safety auxiliary warning device to reduce the difficulty of setting and improve the efficiency of debugging equipment in the protection room.

[0025] In order to make the technical personnel in this field better understand the scheme of the present invention, the embodiments of the present invention are described below with reference to the accompanying drawings. In addition, the embodiments shown below do not limit the content of the invention recorded in the claims. In addition, the entire contents of the structures represented by the following embodiments are not limited to those necessary for the solutions of the invention recorded in the claims.

[0026] like Figure 1As shown, the safety auxiliary warning device provided by the embodiment of the present invention mainly includes a transmitter 10 and a receiver 20, wherein the transmitter 10 is used to transmit a signal to the receiver 20, and preferably the transmitter 10 transmits a laser signal 60 to the receiver 20, and the laser signal 60 has a smaller divergence angle, so that the transmitter 10 and the receiver 20 can meet the signal reception requirements with a smaller structure. On this basis, the path of the laser signal 60 between the transmitter 10 and the receiver 20 covers the area of ​​the protection screen cabinet 30 in the plane where the door of the protection screen cabinet 30 is located, and the transmitter 10 and the receiver 20 are both arranged on the door side of the protection screen cabinet 30, so that the path of the laser signal 60 can pass through the door when the door of the protection screen cabinet 30 is opened at any angle. That is, in the above structure, when the cabinet door of the protection screen cabinet 30 is in a normally closed state, the laser signal 60 between the transmitting unit 10 and the receiving unit 20 is unobstructed, and the receiving unit 20 can fully receive the laser signal 60. However, when the cabinet door of the protection screen cabinet 30 is opened by mistake, since the path of the laser signal 60 passes through the cabinet door of the protection screen cabinet 30 in the open state, the laser signal 60 will be blocked by the cabinet door or deflected by the panel of the cabinet door. At this time, the receiving unit 20 cannot smoothly receive the laser signal 60.

[0027] On the basis of the above-mentioned setting structure of the transmitting part 10 and the receiving part 20, the safety auxiliary warning device provided by the embodiment of the present invention also includes a controller 40, which is used to be electrically connected to both the transmitting part 10 and the receiving part 20. It should be noted that the electrical connection here specifically refers to the signal connection between the controller 40 and the transmitting part 10 and the receiving part 20, so as to detect in real time whether the receiving part 20 receives the laser signal 60. The controller 40 can be set separately, or it can be integrated on the panel structure of any one of the transmitting part 10 and the receiving part 20. At the same time, the controller 40 does not act when the transmitting part 10 and the receiving part 20 are in smooth communication, or sends a normal signal. When the laser signal 60 between the transmitting part 10 and the receiving part 20 is disconnected, the controller 40 adjusts at least one of the transmitting part 10 and the receiving part 20 to send a warning signal to prompt the operator that the cabinet door of the protective screen cabinet 30 between the transmitting part 10 and the receiving part 20 that does not require operation is abnormally opened, so that the operator can handle it in time.

[0028] The safety auxiliary warning device provided by the embodiment of the present invention forms a communication path of the laser signal 60 through the transmitting part 10 and the receiving part 20, so as to provide auxiliary warning to the protection screen cabinet 30 in the area covered by the laser signal 60. Specifically, the path of the laser signal 60 between the transmitting part 10 and the receiving part 20 passes through the cabinet door of the protection screen cabinet 30 in the open state, so that when the cabinet door is opened, the cabinet door cuts off or deflects the laser signal 60, so that the laser signal 60 is disconnected; correspondingly, the controller 40 sends a warning signal when the laser signal 60 is disconnected, and the operator is fed back to deal with the cabinet door opened by mistake in time. The above structure only needs to set the transmitting part 10 and the receiving part 20 to realize the auxiliary warning function. Compared with the current magnetic retractable safety warning belt or movable column retractable isolation belt, the transmitting part 10 and the receiving part 20 do not need to be supported by load bearing, only need a simple position setting, and can be used at any time, thereby reducing the risk of failure. The operation is simple and effective, and the efficiency of arranging the safety auxiliary warning device during the equipment debugging process can be smoothly improved.

[0029] On the basis of the above embodiments, the controller 40 adjusts the warning signal emitted by at least one of the transmitting unit 10 and the receiving unit 20 to be quickly and obviously perceived by the operator to achieve the warning effect. Taking the component that emits the warning signal as an example, in some embodiments of the present invention, the warning signal is a sound signal, and the transmitting unit 10 is specifically provided with a speaker 110 or a buzzer, which is also electrically connected to the controller 40, and the warning signal can be a siren-like sound signal emitted by the speaker 110, or a buzzer sound signal emitted by the buzzer. In other embodiments of the present invention, a warning light 120 can also be provided on the transmitting unit 10, which is also electrically connected to the controller 40, and the warning signal is a red or yellow flashing signal emitted by the warning light 120, and the operator can quickly perceive the abnormal state of the protective screen cabinet 30 through the light color of the warning light 120.

[0030] It should be noted that the sound and light signals are warning signals that can be directly perceived. The warning signal adjusted by the controller 40 can be one or a combination of the sound and light signals. At the same time, similar to the transmitting unit 10, the receiving unit 20 can also be provided with a component that emits sound and light signals, which will not be repeated here.

[0031] Furthermore, in order to improve the convenience of setting up the safety auxiliary warning device, it is preferred that both the transmitter 10 and the receiver 20 are fixedly set on the protection screen cabinet 30, and the smooth passage of the laser signal 60 is realized through the port protruding from the plane where the cabinet door of the protection screen cabinet 30 is located. The transmitter 10 and the receiver 20 can be fixed on the protection screen cabinet 30 by bonding, bolting or magnetic connection. Considering that the transmitter 10 and the receiver 20 have the need to be transported to different protection screen cabinets 30 and set at different heights on the protection screen cabinet 30, it is preferred that both the transmitter 10 and the receiver 20 are provided with a magnetic back cover 50 to be fixed to the protection screen cabinet 30 by magnetic connection. The magnetic connection method only requires the structural design of the magnetic back cover 50 for the transmitter 10 and the receiver 20, and can be set at any position on the side wall of the protection screen cabinet 30 as needed, thereby improving the convenience of the structural setting of the safety auxiliary warning device.

[0032] In addition, it should be noted that the ports on the transmitting unit 10 and the receiving unit 20 are located on the same straight line, so that the laser signal 60 can pass smoothly. In order to improve the standardized setting of the safety auxiliary warning device, the transmitting unit 10 and the receiving unit 20 are preferably set at the same horizontal height on the protection screen cabinet 30, and the path of the laser signal 60 is along the horizontal direction. Through the standardized setting, the structural similarity of the safety auxiliary warning device when used in different protection screen cabinets 30 can be improved, thereby improving the use stability of the safety auxiliary warning device.

[0033] Furthermore, in order to avoid failure of the receiving unit 20 and failure to provide feedback to the controller 40 when the cabinet door is opened, in some embodiments of the present invention, a single transmitting unit 10 is docked with two receiving units 20. Specifically, a single transmitting unit 10 is capable of transmitting two laser signal beams 60, and the two laser signal beams 60 have a certain angle with the transmitting unit 10 as the vertex, while two receiving units 20 are provided on the other side of the protective screen cabinet 30. The two receiving units 20 respectively receive a laser signal 60, and when the laser signal 60 transmission between any receiving unit 20 and the transmitting unit 10 is disconnected, the controller 40 will adjust at least one of the transmitting unit 10 and the receiving unit 20 to send a warning signal. It should be noted that the two receiving units 20 can serve as backup for each other in receiving the two laser signal beams 60 to avoid failure to provide feedback on the door opening when a single receiving unit 20 fails. At the same time, the two laser signal beams 60 can be set as needed. For example, the two laser signal beams 60 can be set in a single horizontal and another inclined manner, that is, one receiving unit 20 and the transmitting unit 10 are set at the same horizontal height, while the other receiving unit 20 is offset from the transmitting unit 10 in the horizontal direction; and at the same time, the two laser signal beams 60 can also be set at the same angle and length, that is, the two receiving units 20 are set at intervals, and the single transmitting unit 10 is set on the symmetry line of the two receiving units 20 to emit the laser signal 60.

[0034] In the safety auxiliary warning device provided in the embodiment of the present invention, the transmitting part 10 is specifically provided with a power supply 130, a switch 140 and a laser emitter 150, wherein the power supply 130 is used to supply power to the laser emitter 150, the warning component and the controller 40 on the transmitting part 10, and the switch 140 is used to control the on and off of the power supply 130. The transmitting part 10 can be freely set and the laser emitter 150 will only emit a laser signal 60 when the switch 140 adjusts the power supply 130 to start, thereby avoiding the warning component of the transmitting part 10 sending an abnormal signal during the assembly and adjustment process.

[0035] In addition, for safety auxiliary warning devices that need to frequently adjust the use position, the transmitter 10 and the receiver 20 can also be supported by support legs, and preferably the transmitter 10 and the receiver 20 are supported by two support legs of equal height. On this basis, when setting the safety auxiliary warning device for the protection screen cabinet 30, there is no need to assemble the transmitter 10 and the receiver 20, but only the support legs with the transmitter 10 and the receiver 20 installed need to be positioned so that the transmitter 10 and the receiver 20 are close to the protection screen cabinet 30 and spaced from the protection screen cabinet 30, so that the laser signal 60 of the transmitter 10 and the receiver 20 can pass through the cabinet door of the protection screen cabinet 30 when it is open. When it is necessary to set up other safety auxiliary warning devices for the protection screen cabinet 30, it is only necessary to move the support legs and set them in a new position to achieve the position change of the transmitter 10 and the receiver 20, which is convenient to operate and will not affect the structure of the protection screen cabinet 30.

[0036] Furthermore, in some embodiments of the present invention, for regularly arranged protection screen cabinets 30, taking two protection screen cabinets 30 arranged in the same direction as an example, the path of the laser signal 60 in the safety auxiliary warning device covers at least two protection screen cabinets 30, so as to be able to simultaneously detect the mis-opening of the cabinet doors of the two protection screen cabinets 30. It also only requires a set of transmitting unit 10 and receiving unit 20 without other settings. Compared with existing warning tapes and other solutions, it can significantly reduce the structural complexity of the safety auxiliary warning device and improve the convenience of using the safety auxiliary warning device.
