[0044] The core of the utility model is to provide a warning device to improve the effectiveness of the warning device in warning operators and prevent operators from walking into the wrong equipment area.
[0045] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0046] The operation and maintenance of nuclear power plants is a high-risk, high-tech job involving many complex systems and equipment. Every step of the operator's operation must be accurate and correct, and any small mistake may lead to serious consequences. In order to prevent operators from going to the wrong location when performing maintenance or other operations in nuclear power plants, which may cause a series of problems, including but not limited to reactor jumps, parameter fluctuations, and the risk of radioactive leakage, it is necessary to effectively isolate and warn the equipment and related areas.
[0047] Traditional warning devices do not have a unified standard for isolating equipment areas. They are generally isolated through isolation belts, and text reminder warning signs are set up to remind and warn operators. However, the actual isolation effect of the areas that need warnings is limited, and effective warnings cannot be guaranteed. There is still a problem of reduced safety status of nuclear power plant units due to operators walking into the wrong area, inappropriate maintenance activities, etc.
[0048] For this reason, Figure 1 As shown, the embodiment of the utility model discloses a warning device, including a warning box 100 and an optical signal component 200. The optical signal transmitter 201 arranged on the warning box 100 emits an optical signal, and the optical signal receiver 202 arranged on the support 300 opposite to the warning box 100 receives the optical signal emitted by the optical signal transmitter 201. When the operator walks into the wrong equipment area, the warning component 101 can remind the operator, thereby improving the effectiveness of the warning to the operator, preventing the operator from walking into the wrong equipment area, helping to reduce engineering wiring, facilitating installation and debugging, and improving the practicality of the warning device.
[0049] The following will be combined Figures 1 to 6 The warning device disclosed in the embodiment of the utility model is specifically explained and illustrated.
[0050] like Figure 1As shown, the warning box 100 is provided with a warning component 101 and an identity recognition area 102. The identity of the operator can be verified through the identity recognition area 102, so as to determine whether the operator meets the equipment area, so as to avoid the operator from going to the wrong equipment area. At the same time, a reminder can be issued through the warning component 101 to warn the operator that he has gone to the wrong equipment area. Among them, the identity recognition area 102 may include a fingerprint recognition area, and may also include a camera module and an identification display screen, so as to verify the identity of the operator by means of face recognition. The warning component 101 includes a warning light 1011 and / or an alarm 1012, that is, the alarm 1012 can be set on the warning box 100 to issue an alarm to remind the operator that he has gone to the wrong equipment area, or the warning light 1011 can be set on the warning box 100 to remind the operator that he has gone to the wrong equipment area by frequent flashing or color distinction, such as a red light is on. In this embodiment, Figure 1 As shown, the identity recognition area 102 includes a card swiping area 1021. The operator inserts the work card corresponding to the equipment area into the card slot of the card swiping area 1021 or sticks the work card on the sensing area to verify the identity of the operator to avoid the operator from going to the wrong equipment area. In addition, a warning light 1011 and an alarm 1012 are provided on the warning box 100, so that an alarm sound is emitted and the light flashes frequently to remind the operator to go to the wrong equipment area.
[0051] Furthermore, the warning box 100 includes a cavity 107 for installing components. The components include a control device 108 and a power supply component 109. A partition 110 is provided in the cavity 107 to separate the control device 108 and the power supply component 109. Specifically, Figure 5 and Figure 6 As shown, the partition 110 is located in the middle of the cavity 107 of the warning box 100 to divide the cavity 107 of the warning box 100 into an upper and lower area, and the control device 108 is located in the upper area of the cavity 107, and the power supply component 109 is located in the lower area of the cavity 107. At the same time, a notch 111 is provided on the warning box 100, and the notch 111 is located in the upper part of the warning box 100 and corresponds to the position of the control device 108, so that when the warning component 101 and the identity recognition area 102 are located in the notch 111, it is convenient to connect with the control device 108. In addition, as shown in FIG. Figure 1 and Figure 6As shown, a first door 1111 is movably provided at the slot 111 to protect the warning component 101 and the identification area 102 in the slot 111, to prevent dust and water stains from entering, and to prevent human damage, and a second door 112 is movably provided at a position corresponding to the power component 109, so as to replace and repair the power component 109. In this embodiment, the power component 109 can be connected to an external power source through a cable 114, so as to provide power for the warning device. At the same time, in order to facilitate the opening and closing of the first door 1111 and the second door 112, a gripping portion 113 is respectively provided on the first door 1111 and the second door 112, and the first door 1111 and the second door 112 can be movably connected to the warning box 100 through a magnetic suction piece. When the first door 1111 and the second door 112 need to be opened, the first door 1111 and the second door 112 only need to be pulled by the gripping portion 113 to overcome the gravitational force of the magnetic suction piece to open the first door 1111 and the second door 112.
[0052] like Figure 1 As shown, the optical signal assembly 200 includes an optical signal transmitter 201 disposed on the warning box 100 and an optical signal receiver 202 disposed opposite to the optical signal transmitter 201. The optical signal receiver 202 is disposed on a support 300 opposite to the warning box 100 to receive the optical signal emitted by the optical signal transmitter 201. A passage 400 is formed between the support 300 and the warning box 100 for easy access of operators. The optical signal assembly 200, the identity recognition area 102 and the warning assembly 101 are linked to each other. When the operator mistakenly enters the entrance and exit passage 400 formed between the support 300 and the warning box 100, the optical signal propagation path is blocked, and the warning component 101 performs a reminder action to warn the operator to verify his identity; when the operator verifies his identity through the identity recognition area 102, the optical signal component 200 performs a stop action, and the operator can enter the equipment area through the entrance and exit passage 400 formed between the support 300 and the warning box 100; when the operator verifies that the identity is incorrect through the identity recognition area 102, the warning component 101 performs a reminder action to warn the operator that he has walked into the wrong equipment area.
[0053] like Figure 3 and Figure 4As shown, in a specific embodiment, the optical signal component 200 adopts a laser signal system. The optical signal transmitter 201 includes a laser transmitter element 2011 and a laser emission hole 2012 disposed on the laser transmitter element 2011, and the optical signal receiver 202 includes a laser receiving element 2021 and a laser receiving panel 2022 disposed on the laser receiving element 2021, so that the laser receiving panel 2022 on the laser receiving element 2021 can receive the laser signal emitted by the laser emission hole 2012 on the laser transmitter element 2011. During normal operation, the laser emission hole 2012 on the laser transmitter element 2011 emits laser, and the laser receiving panel 2022 on the laser receiving element 2021 will emit a wireless signal after receiving the laser; when the operator is located on the path of the laser signal propagation, the propagation of the laser signal is blocked, so that the laser receiving panel 2022 on the laser receiving element 2021 cannot receive the laser and cannot feedback the signal, and at this time the warning component 101 issues a reminder.
[0054] The laser emitter element 2011 is provided with a built-in power supply, a laser emitting device, and a laser signal reflection monitoring device. The laser is emitted to the laser receiving element 2021 through the laser emitting hole 2012 of the laser emitter element 2011. The laser receiving panel 2022 of the laser receiving element 2021 receives the laser and reflects it. When the laser signal reflection monitoring device inside the laser emitter element 2011 collects the laser reflection signal, it sends a signal to the control device 108, and the warning light 1011 is always on green. When external factors interfere with the laser emitted by the laser emitter element 2011, the laser receiving element 2021 cannot reflect the laser, and the laser emitter element 2011 cannot receive the laser reflection signal of a specific frequency. The warning light 1011 is always on red, and the alarm 1012 sounds an alarm.
[0055] Furthermore, when the positions of the optical signal transmitter 201 and the optical signal receiver 202 are calibrated, whether the optical signal transmitted by the optical signal transmitter 201 can be stably received by the optical signal receiver 202 can be determined by checking whether the warning light 1011 is always green.
[0056] In order to more conveniently adjust the optical signal assembly 200 so that the optical signal emitted by the optical signal transmitter 201 can be received by the optical signal receiver 202, in a specific embodiment, the optical signal receiver 202 can be kept fixed, and the optical signal transmitter 201 can be slidably arranged on the warning box 100 through the first sliding assembly 103, and the position of the optical signal transmitter 201 is adjusted by moving the optical signal transmitter 201 until the optical signal emitted by the optical signal transmitter 201 can be received by the optical signal receiver 202, and then locked and fixed by the first locking member 106. The first sliding assembly 103 includes a first slide rail 104 arranged on the warning box 100 and a first slide member 105 slidably matched with the first slide rail 104, and the optical signal transmitter 201 is arranged on the first slide member 105. In this embodiment, the first slide rail 104 is arranged on the side of the warning box 100 and is flush with the lower edge of the warning box 100. At the same time, the first slide rail 104 extends from one end of the warning box 100 to the other end, or the first slide rail 104 extends a certain distance from one end of the warning box 100 to ensure a larger adjustment space for the optical signal transmitter 201.
[0057] Furthermore, if Figure 2 As shown, the first slide rail 104 includes a first bottom plate 1041 and a first side plate 1042 disposed on both sides of the first bottom plate 1041, and the first side plate 1042 and the first bottom plate 1041 are surrounded to form a first slide groove 1043. Among them, the first bottom plate 1041 and the first side plate 1042 can adopt a split structure and be connected and fixed by welding to form the first slide groove 1043. Of course, an integrated structure can also be adopted to form the first slide groove 1043 by bending, which is not limited in this article. In addition, the first sliding member 105 is located in the first slide groove 1043 and can slide along the first slide groove 1043, thereby driving the optical signal transmitter 201 located on the first sliding member 105 to move to adjust the position of the optical signal transmitter 201. At the same time, a first limiting portion is provided on the first side plate 1042 to prevent the first sliding member 105 from falling out. In this embodiment, the first sliding member 105 can be a rectangular plate, and the optical signal transmitter 201 is fixed to the middle position of the first sliding member 105 by bonding, bolting or welding. The first sliding member 105 is installed in the first slide groove 1043, and the first limiter can be a first folding plate inclined from the edge of the first side plate 1042 to the first slide groove 1043, and the angle between the first folding plate and the first side plate 1042 is less than 90°, until one end of the first folding plate is in clearance with the first sliding member 105, while ensuring that the first sliding member 105 slides smoothly along the first slide groove 1043, it can prevent the first sliding member 105 from falling out of the first slide groove 1043.
[0058] Of course, if Figure 2 and Figure 3As shown, the first sliding member 105 and the first slide rail 104 may also be connected by means of an engagement connection to ensure that the first sliding member 105 slides smoothly along the first slide groove 1043 while preventing the first sliding member 105 from falling out of the first slide groove 1043 .
[0059] In a specific embodiment, if Figure 2 As shown, the first side plate 1042 of the first slide rail 104 is bent to form a first hook portion 1044, i.e., a first limit portion, and the angle between the side walls of the first hook portion 1044 is 90°, so as to form a first engagement space 1045 that is convenient for the first sliding member 105 to engage. Figure 3 As shown, the first sliding member 105 includes a first sliding bottom plate 1051 and first sliding side plates 1052 disposed on both sides of the first sliding bottom plate 1051. The first sliding bottom plate 1051 and the first sliding side plates 1052 can be of a split structure and fixedly connected by welding to form an installation space for installing the optical signal transmitter 201. Of course, an integrated structure can also be adopted to form the installation space by bending, which is not limited in this article. The optical signal transmitter 201 is disposed on the first sliding bottom plate 1051, and the first sliding side plate 1052 is bent to form a second hook claw portion 1053, and a second engagement space 1054 is formed between the second hook claw portion 1053 and the first sliding bottom plate 1051 to facilitate the engagement of the first hook claw portion 1044. By extending the first hook portion 1044 of the first slide rail 104 into the second engagement space 1054 and the second hook portion 1053 of the first sliding member 105 into the first engagement space 1045, the second hook portion 1053 and the first hook portion 1044 engage with each other, thereby ensuring that the first sliding member 105 slides smoothly along the first slide groove 1043 and preventing the first sliding member 105 from slipping out of the first slide groove 1043. It should be noted that in order to prevent the optical signal transmitter 201 from affecting the movement of the first sliding member 105 along the first slide groove 1043, a first avoidance gap 1055 is provided between the optical signal transmitter 201 and the second hook portion 1053.
[0060] Furthermore, the first locking member 106 includes a first threaded hole 1061 provided on the first sliding bottom plate 1051 and a first fastener 1062 matched with the threaded hole. When the optical signal transmitter 201 is moved to a suitable position, the first fastener 1062 of the first sliding member 105 is screwed so that the first fastener 1062 is pressed against the first bottom plate 1041 of the first slide rail 104, thereby fixing the first sliding member 105. In this embodiment, the first fastener 1062 can be, but is not limited to, a self-tapping screw.
[0061] In order to more conveniently adjust the optical signal assembly 200 so that the optical signal emitted by the optical signal transmitter 201 can be received by the optical signal receiver 202, in a specific embodiment, the optical signal transmitter 201 can also be kept fixed, and the optical signal receiver 202 can be slidably arranged on the support 300 through the second sliding assembly 301, and the support 300 can be a flat support structure such as a wall. The position of the optical signal receiver 202 is adjusted by moving the optical signal receiver 202 until the optical signal receiver 202 can receive the optical signal emitted by the optical signal transmitter 201, and then locked and fixed by the second locking member 304. Among them, the second sliding assembly 301 includes a second slide rail 302 arranged on the support 300 and a second slide member 303 slidably matched with the second slide rail 302, and the optical signal receiver 202 is arranged on the second slide member 303. In this embodiment, the second slide rail 302 is flush with the lower edge of the support 300. When the support 300 is a wall, the lower side of the second slide rail 302 is flush with the ground. At the same time, the second slide rail 302 extends from one end of the support 300 to the other end, or the second slide rail 302 extends from one end of the support 300 by a certain distance to ensure a larger adjustment space for the optical signal receiver 202 .
[0062] Furthermore, if Figure 1 As shown, the second slide rail 302 includes a second bottom plate 3021 and second side plates 3022 disposed on both sides of the second bottom plate 3021, and the second side plates 3022 and the second bottom plate 3021 are arranged to form a second slide groove 3023. The second side plates 3022 and the second bottom plate 3021 can adopt a split structure and be connected and fixed by welding to form the second slide groove 3023. Of course, an integrated structure can also be adopted to form the second slide groove 3023 by bending, which is not limited in this article. In addition, the second sliding member 303 is located in the second slide groove 3023 and can slide along the second slide groove 3023, thereby driving the optical signal receiver 202 located on the second sliding member 303 to move to adjust the position of the optical signal receiver 202. At the same time, a second limiting portion is provided on the second side plate 3022 to prevent the second sliding member 303 from falling out.
