[0033] The embodiments of the present invention will be further described below with reference to the drawings. In the description of the present invention, it should be noted that the orientation or positional relationship indicated by the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc. is based on the orientation or positional relationship shown in the drawings, and is only for the convenience of simplifying the description of the present invention, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be construed as a limitation to the present invention. In addition, the terms "first", "second", "third" are only used for descriptive purposes and cannot be construed as indicating or implying relative importance. Among them, the terms "first position" and "second position" are two different positions

[0034] Figure 1 is a schematic diagram of the safety warning device for chemical engineering according to an embodiment of the present invention Figure 2 is Figure 1 a schematic diagram of the mounting plate of the safety warning device for chemical engineering shown. As Figure 1 and Figure 2 shown, the safety warning device for chemical engineering includes a fixing plate 1, a mounting plate 2, a warning light 3, an elastic component 4, an infrared sensor (not shown) and a controller (not shown). An embedding groove is formed on the first surface of the fixing plate 1, and a storage groove 101 is formed on the groove wall of at least one side of the embedding groove; the mounting plate 2 is arranged in the embedding groove; the warning light 3 is installed on the mounting plate 2; the elastic component 4 is fixed in the storage groove 101 and abuts against the side wall of the corresponding mounting plate 2; the infrared sensor detects infrared signals in real time; the input end of the controller is communicatively connected to the output end of the infrared sensor, and the output end of the controller is communicatively connected to the control end of the warning light 3

[0035] In use, the warning light 3 is installed on the mounting plate 2, and the mounting plate 2 is placed in the embedding groove on the fixing plate 1. At the same time, the elastic component 4 fixed in the storage groove 101 opened on the groove wall of the embedding groove abuts against the side wall of the mounting plate 2, applying an extrusion force to the mounting plate 2 so that the mounting plate 2 abuts against the other side groove wall of the embedding groove, thereby stably embedding the mounting plate 2 in the embedding groove. Then, the fixing plate 1 is placed at the construction site of the chemical engineering project. The infrared sensor detects the infrared signal in the long-distance range in real time and transmits the detected infrared signal data to the controller in real time. The controller receives the infrared signal data and makes a judgment. When it is judged that the received infrared signal data is a human body infrared signal, the controller outputs an alarm signal to the control end of the warning light 3 to control the warning light 3 to emit a warning light to warn people not to approach further and keep away.

[0036] By adopting the safety warning device for chemical engineering projects of the present utility model, the infrared sensor is used to monitor whether there are people approaching in the long-distance range, and after detecting the presence of people, the warning light 3 is controlled to emit a warning light to prevent people from approaching further, which can prevent irrelevant people from keeping a relatively long distance from the construction site of the chemical engineering project and prevent danger from occurring.

[0037] As Figure 1 shown, in this embodiment, the fixing plate 1 is a cuboid plate body, and a square embedding groove is opened at about the center position on its upper surface. As Figure 2 shown, the mounting plate 2 is set as a square ring with a through middle part. The cross-sectional contour of the mounting plate 2 matches the embedding groove and is slightly smaller than the embedding groove so as to be smoothly placed into the embedding groove. The warning light 3 is set as a square matching the hollow part of the mounting plate 2 and is embedded in the mounting plate 2. Figure 1A storage groove 101 is provided on the lower side wall of the embedding groove. The lower end of the elastic component 4 is fixed to the bottom of the storage groove 101, and the upper end abuts against the lower side wall of the mounting plate 2. By means of the elastic force exerted by the elastic component 4 on the mounting plate 2, the upper side wall of the mounting plate 2 is tightly abutted against the upper side wall of the embedding groove, realizing the stable connection between the mounting plate 2 and the fixing plate 1 in the embedding groove. According to the actual application situation, the specific shape and size of the fixing plate 1, the embedding groove and the mounting plate 2 can all be adjusted, and the specific connection method between the warning light 3 and the mounting plate 2 can also be adjusted. The warning light 3 can emit warning-colored light, such as red light, when detecting a person, or can flash continuously, as long as it can play a warning role to prevent people from approaching further. The elastic component 4 can adopt any form of structural combination, as long as it can be fixed in the storage groove 101 and apply an elastic force to the mounting plate 2 so that the mounting plate 2 can be stably arranged in the embedding groove. The infrared sensor can be selected from any commercially available specification and model suitable for the construction site of chemical engineering projects, and can be installed at any position on the fixing plate 1 or the mounting plate 2, or can be directly installed at the construction site. The control logic for the controller to control the warning light 3 to turn on according to the infrared signal data detected by the infrared sensor can be realized according to the existing mature algorithms, and its specific working principle will not be elaborated here.

[0038] Figure 3 is Figure 1 a schematic diagram of the elastic component of the safety warning device for chemical engineering as shown. As Figure 3 shown, optionally, the elastic component 4 includes an elastic member 41, a support leg 42 and a positioning plate 43. The first end of the elastic member 41 is fixedly connected to the bottom of the storage groove 101; the first end of the support leg 42 is fixedly connected to the second end of the elastic member 41; the surface of the positioning plate 43 facing the bottom of the storage groove 101 is fixedly connected to the second end of the support leg 42, and the surface of the positioning plate 43 facing away from the bottom of the storage groove 101 abuts against the mounting plate 2. This setting simplifies the structural composition of the elastic component 4 and is convenient for assembly and operation.

[0039] As Figure 3As shown, in this embodiment, the lower end of the elastic member 41 is fixed to the bottom of the storage groove 101. The support leg 42 includes a horizontal section and an inclined section connected to the horizontal section. The upper end of the elastic member 41 is fixedly connected to the horizontal section, and the upper end of the inclined section is fixedly connected to the positioning plate 43. In this embodiment, the length of the positioning plate 43 is approximately equal to the width of the storage groove 101. When the elastic member 41 is in its natural state, the positioning plate 43 is slightly higher than the depth of the storage groove 101 and occupies a part of the space of the embedding groove. When the mounting plate 2 is placed into the embedding groove, it presses the positioning plate 43, and the positioning plate 43 further presses the support leg 42 and the elastic member 41 connected thereto. The elastic member 41 is compressed and deformed, so that the positioning plate 43 moves toward the bottom of the storage groove 101, releasing the space of the embedding groove, and the mounting plate 2 can be smoothly placed into the embedding groove. At the same time, the upward elastic force generated after the elastic member 41 is compressed and deformed acts on the positioning plate 43, causing the positioning plate 43 to further press the mounting plate 2 abutted thereto upward, and further causing the mounting plate 2 to press Figure 3 the upper side groove wall of the embedding groove in Figure 3 , and closely abutting against the upper side groove wall, that is, the mounting plate 2 is stably arranged in the embedding groove on the surface of the fixing plate 1 without shaking. In order to enable the positioning plate 43 to move up and down stably in the storage groove 101, as Figure 1 shown, in this embodiment, two elastic members 41 and two support legs 42 are provided. The two support legs 42 are fixedly connected to the positioning plate 43 at intervals, providing stable support for the positioning plate 43 to prevent the positioning plate 43 from tilting during the movement. According to the actual application situation, the elastic member 41 can be any structure with elastic properties, the set number of the elastic member 41 and the support leg 42 can be adjusted, and the specific shape and size of the support leg 42 and the positioning plate 43 can be adjusted. Figure 3 As shown, in this embodiment, two elastic members 41 and two support legs 42 are provided in total. The two support legs 42 are fixedly connected to the positioning plate 43 at intervals, providing stable support for the positioning plate 43 to avoid the positioning plate 43 from tilting during the movement. According to the actual application situation, the elastic member 41 can be any structure with elastic properties, the set number of the elastic member 41 and the support leg 42 can be adjusted, and the specific shape and size of the support leg 42 and the positioning plate 43 can be adjusted.

[0040] Optionally, the elastic member 41 is set as a spring. Selecting a spring makes the raw materials easy to obtain and is beneficial to reducing costs.

[0041] Optionally, the elastic assembly 4 further includes a guide post 44. The elastic member 41 is sleeved on the guide post 44. The first end of the guide post 44 is fixedly connected to the bottom of the storage groove 101, and the second end of the guide post 44 penetrates through the support leg 42. By providing the guide post 44, when the elastic member 41 moves up and down during elastic deformation, it can only move along the extension direction of the guide post 44, avoiding displacement deviation of the elastic member 41 and further affecting the movement of the positioning plate 43.

[0042] As Figure 3As shown, in this embodiment, the guide post 44 is set as a cylinder, vertically arranged, with a spring sleeved around its circumference. The lower end is fixed to the bottom of the storage groove 101, and the upper end penetrates through the support leg 42. When the positioning plate 43 is pushed downward by the installation plate 2 to compress the spring, the spring can only be vertically compressed and deformed downward along the guide post 44. When the installation plate 2 is taken out and the extrusion on the positioning plate 43 is released, the spring can only vertically recover its deformation upward along the guide post 44.

[0043] Optionally, the elastic component 4 further includes a limit plate 45, which is fixedly connected to the end of the second end of the guide post 44. By setting the limit plate 45, the maximum movement range of the support leg 42 is restricted, preventing the positioning plate 43 from losing the external extrusion effect when the installation plate 2 is taken out, and preventing the support leg 42 from detaching from the guide post 44 during the upward movement driven by the spring when the spring recovers its deformation.

[0044] As Figure 3 shown, in this embodiment, the limit plate 45 is set as a thin plate, fixed to the end of the upper end of the guide post 44. The cross-sectional area of the limit plate 45 is larger than that of the guide post 44 and also larger than the through hole where the guide post 44 penetrates through the support leg 42. According to the actual application situation, the shape and size of the limit plate 45 can be adjusted as long as it can prevent the support leg 42 from detaching from the guide post 44.

[0045] Optionally, the end of the positioning plate 43 facing the side wall of the storage groove 101 is provided with a chamfer. By setting the chamfer, when the positioning plate 43 moves toward the bottom of the storage groove 101 under the extrusion of the installation plate 2, or when the installation plate 2 is taken out and the positioning plate 43 loses the external extrusion effect and moves away from the bottom of the storage groove 101 under the action of the elastic member 41, the contact area with the groove wall of the storage groove 101 can be reduced, thereby reducing the friction force between the two.

[0046] As Figure 3 shown, in this embodiment, chamfers of about 45° are provided at both ends of the left and right sides of the positioning plate 43. According to the actual application situation, the specific setting angle of the chamfer can be adjusted.

[0047] Optionally, a plurality of storage grooves 101 are provided, and an elastic component 4 is arranged in each storage groove 101. Each elastic component 4 abuts against the side wall of the corresponding installation plate 2. By setting a plurality of elastic components 4, when the installation plate 2 is placed in the embedding groove, the plurality of elastic components 4 can simultaneously apply an extrusion force to the installation plate 2, further improving the stability of the installation plate 2 arranged in the embedding groove.

[0048] For example, it can be in Figure 1On the lower groove wall of the embedded groove, two storage grooves 101 are spaced apart. Elastic components 4 are respectively arranged in the two storage grooves 101. The two elastic components 4 respectively abut against the mounting plate 2, applying an upward extrusion force to the mounting plate 2, so that the mounting plate 2 can abut more firmly against the upper groove wall of the embedded groove. For another example, in addition to opening the storage groove 101 on the lower groove wall of the embedded groove, the storage groove 101 can also be opened on the left groove wall of the embedded groove. After the mounting plate 2 is arranged in the embedded groove, the elastic component 4 in the lower storage groove 101 applies an upward extrusion force to it, making it abut against the upper groove wall of the embedded groove. At the same time, the elastic component 4 in the left storage groove 101 applies a rightward extrusion force to it, making it abut against the right groove wall of the embedded groove. Then, the upper side wall and the right side wall of the mounting plate 2 are both in close contact with the groove wall of the embedded groove. Therefore, no matter how many storage grooves 101 are opened on any groove wall of the embedded groove, the stability of the mounting plate 2 arranged in the embedded groove can be improved, and the mounting plate 2 can be prevented from detaching from the fixing plate 1.

[0049] Optionally, the safety warning device for chemical engineering further includes a buzzer (not shown). The input end of the buzzer is communicatively connected to the output end of the controller. By adding the buzzer, when it is detected that someone is approaching, in addition to controlling the warning light 3 to emit light, the controller also controls the buzzer to emit a sound alarm to further warn the approaching person and prevent the person from approaching further. The buzzer can be installed on the fixing plate 1 or the mounting plate 2, or can be installed at the construction site of chemical engineering.

[0050] Optionally, the safety warning device for chemical engineering further includes an oxygen detector (not shown). The output end of the oxygen detector is communicatively connected to the input end of the controller. The oxygen detector continuously monitors the oxygen concentration at the construction site of chemical engineering and transmits the monitored oxygen concentration data to the controller in real time. The controller pre-stores an oxygen concentration threshold internally. When the received oxygen concentration data is less than the oxygen concentration threshold, it indicates that the oxygen concentration is too low. At this time, the controller controls the warning light 3 to emit warning light, and when there is a buzzer, it also controls the buzzer to emit a sound alarm to prompt the staff to take relevant measures.

[0051] The control logic for the controller to control the warning light 3 to emit warning light according to the monitoring result of the oxygen detector can be achieved according to the existing mature algorithms, and its specific working principle will not be elaborated here.

[0052] Optionally, the safety warning device for chemical engineering further includes a harmful gas detector (not shown), and the output end of the harmful gas detector is communicatively connected to the input end of the controller. The harmful gas detector monitors the concentration of harmful gases at the construction site of chemical engineering in real time, and transmits the monitored harmful gas concentration data to the controller in real time. A harmful gas concentration threshold is pre-stored inside the controller. When the received harmful gas concentration data is greater than the harmful gas concentration threshold, it indicates that the harmful gas concentration is too high. At this time, the controller controls the warning light 3 to emit a warning light. When there is a buzzer, it also controls the buzzer to emit a sound alarm to prompt the staff to take relevant measures.

[0053] The control logic for the controller to control the warning light 3 to emit a warning light according to the monitoring result of the harmful gas detector can be realized according to existing mature algorithms, and its specific working principle will not be elaborated here.

[0054] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some of the technical features.
