Technical Field

[0001] The present invention relates to the field of hazardous gas monitoring equipment, and in particular to a safety management device for chemical equipment. Background Art

[0002] Humanity and the chemical industry have a close relationship, permeating every aspect of life. In modern life, chemical products are indispensable in almost every aspect, from material needs like clothing, food, housing, and transportation to spiritual needs like culture, art, and entertainment. Some chemical products have played epoch-making roles in human history.

[0003] However, during the production of chemical products, toxic and harmful gases often leak out. These gases not only pollute the environment but also seriously affect the health of workers. The toxic gas hazard is particularly prominent in production processes with outdated equipment and backward processes. To control the impact of toxic and harmful gases on workers' health and take effective measures to control the hazards of toxic gases, a good way is to install safety management devices on chemical equipment to continuously detect toxic and harmful gases.

[0004] Currently, safety management devices for chemical equipment on the market use fixed detection devices that detect harmful gas leaks by fixing sensors in corresponding locations. However, due to the varying locations of potential leaks, the detection devices may not respond in a timely manner, resulting in poor monitoring effectiveness and a lack of timely response, which can endanger the health of workers and reduce safety. Consequently, this leads to poor monitoring effectiveness and low safety. Summary of the Invention

[0005] The present invention provides a safety management device for chemical equipment, which aims to solve the problems of poor monitoring effect, untimely response and low safety of existing safety management devices.

[0006] To achieve the above object, the technical solution of the present invention is:

A catalytic combustion sensor is provided at the bottom of the movable block.

[0010] Furthermore, a top plate is provided on the mounting plate, a driving motor is provided on the top of the top plate, and an output end of the driving motor is connected to the top of the mounting plate.

[0011] Furthermore, an alarm device is provided on the mounting plate, and the alarm device includes an alarm bell and a warning light.

[0012] Furthermore, the lifting structure includes an electric push rod, which is fixed on the mounting plate, and the output end of the electric push rod is connected to the connecting disc.

[0013] Furthermore, the air supply mechanism includes a shell, a protective net is provided at the bottom of the shell, a fan is provided inside the shell, and air outlets are provided on the outer walls around the shell.

[0014] Furthermore, a connecting rod is provided on a side of the fixing frame away from the servo motor, and the fixing frame is rotatably connected to the connecting disc through the connecting rod.

[0015] Furthermore, a rotating shaft is provided on the connecting disc, and the connecting rod is rotatably connected to the connecting disc via the rotating shaft.

[0016] Furthermore, a limiting groove is provided on the lower surface of the fixing frame, and a limiting block located in the limiting groove is provided on the top of the movable block.

[0017] The beneficial effects achieved by the present invention are:

[0026] To facilitate those skilled in the art to understand the present invention, specific embodiments of the present invention are described below with reference to the accompanying drawings.

[0027] like Figures 1 to 5 As shown, the present invention provides a safety management device for chemical equipment, including a mounting plate 1, a connecting disc 4 arranged at the center of the lower surface of the mounting plate 1 through a lifting structure, an air supply mechanism 5 for conveying airflow arranged on the lower surface of the connecting disc 4, and several reciprocating mechanisms 2 arranged around the connecting disc 4 on the lower surface of the mounting plate 1.

[0028] Mounting plate 1 is provided with a top plate 7, atop which is mounted a drive motor 8, the output end of which is connected to the top of mounting plate 1. Driven by drive motor 8, mounting plate 1 can rotate to increase the detection surface. Mounting plate 1 is also provided with an alarm device comprising an alarm bell and a warning light.

[0029] The lifting structure includes an electric push rod 6, which is fixed on the mounting plate 1. The output end of the electric push rod 6 is connected to the connecting disc 4, and the connecting disc 4 can move up and down under the push of the electric push rod 6.

[0030] The air supply mechanism 5 includes a housing 51 , a protective net 52 is provided at the bottom of the housing 51 , a fan 53 is provided inside the housing 51 , and air outlets 54 are provided on the outer walls of the housing 51 .

[0031] The reciprocating mechanism 2 comprises a fixing frame 21 arranged radially along the mounting plate 1, a threaded rod 23 movably arranged on the lower surface of the fixing frame 21, and a connecting member 22 arranged at one end of the fixing frame 21 and rotatably connected to the fixing frame 21, wherein the connecting member 22 is slidably arranged on the lower surface of the mounting plate (1).

[0032] A servo motor 24 is mounted on the end of the fixing bracket 21 adjacent to the connecting member 22. The other end of the fixing bracket 21 is rotatably connected to the connecting disc 4. The output end of the servo motor 24 is connected to the threaded rod 23. A movable block 25 is threadedly connected to the outer side of the threaded rod 23. The catalytic combustion sensor 3 is mounted on the bottom of the movable block 25.

[0033] Furthermore, a connecting rod 26 is provided on a side of the fixing frame 21 away from the servo motor 24 , and a rotating shaft is provided on the connecting disc 4 . The connecting rod 26 is rotatably connected to the connecting disc 4 via the rotating shaft.

[0034] Furthermore, a limiting groove 27 is provided on the lower surface of the fixing frame 21, and a limiting block 28 is provided on the top of the movable block 25, which is located in the limiting groove 27. The mutual cooperation between the limiting groove 27 and the limiting block 28 can prevent the movable block 25 from rotating along with the threaded rod 23.

[0035] The principle of the present invention is described as follows:

[0036] This design mainly provides a reciprocating mechanism 2, which can drive the catalytic combustion sensor 3 to move back and forth, thereby increasing the monitoring range, detecting harmful gases in the first time, improving the monitoring effect, and improving safety.

[0037] When in use, the catalytic combustion sensor 3 is driven to move back and forth by the reciprocating mechanism 2. Under the action of the servo motor 24, the threaded rod 23 is driven to rotate forward or reverse, and the movable block 25 mounted on the threaded rod 23 moves left or right. The catalytic combustion sensor 3 below the movable block 25 can detect harmful gases back and forth. If harmful gases are detected, the alarm sounds and the warning light turns on, thereby prompting the staff to take timely remedial measures.

[0038] The entire detection process has a high degree of automation and can move back and forth to detect harmful gases, which increases the detection surface and can monitor harmful gases in a timely manner, with a wide range of applications.

[0039] The limit block 28 provided on the movable block 25 can move on the limit groove 27, so that the movable block 25 can move left and right smoothly, thereby improving the stability of the entire reciprocating mechanism 2, making it more reliable, and increasing the service life of the reciprocating mechanism.

[0040] In addition, through the provision of the electric push rod 6, through the action of the connecting member 22 and the connecting rod 26, under the push of the electric push rod 6, the connecting disc 4 will move downward, and the connecting member 22 will slide on the mounting plate 1, which can change the angle of the entire reciprocating mechanism, so that the catalytic combustion sensor 3 can move downward until it moves to the lowest point, making it convenient for maintenance personnel to maintain or replace the catalytic combustion sensor 3, thereby improving the efficiency of later maintenance.

[0041] At the same time, through the air supply mechanism 5, the negative pressure formed by the fan 53 can quickly suck the air below into the outer shell 51, and blow it out to the vicinity of the catalytic combustion sensor 3 through the air outlet 54, thereby improving the detection effect, and being able to detect harmful gases more quickly and improve timeliness.
