[0001] This invention belongs to the field of monitoring equipment technology, and in particular relates to a safety monitoring device for university laboratories. Background Technology

[0002] Laboratories are essential facilities for schools and research institutions to conduct talent cultivation, scientific research, and social service activities. Many laboratories use a wide variety of chemicals, flammable and explosive materials, and highly toxic substances. Some experiments are conducted under special environments or conditions such as high temperature, high pressure, ultra-low temperature, vacuum, strong magnetic field, microwave, radiation, high voltage, and high rotation speed. Some experiments may release toxic substances. In recent years, laboratories have frequently experienced fires, poisoning incidents, injuries, and environmental pollution accidents, undoubtedly causing significant property losses to schools and research institutions, and in some cases even resulting in casualties. To prevent the recurrence of these accidents, many laboratories are equipped with safety monitoring equipment.

[0003] However, existing security monitoring equipment generally needs to be fixedly installed on buildings, and it still has the following drawbacks in actual use:

[0004] 1. Existing security monitoring equipment has limited functionality, is inconvenient to clean and maintain, and has poor heat dissipation.

[0005] 2. The existing security monitoring equipment is not secure enough, and in the event of a fire, students alone cannot handle the situation in a timely manner.

[0006] Therefore, existing security monitoring equipment cannot meet the needs of actual use, so there is an urgent need for improved technologies to solve the above problems. Summary of the Invention

The rotating mechanism rotates the monitoring component to one side of the experimental platform, and then the lifting mechanism lowers it. At this time, the monitoring component can be maintained and cleaned, and the fire extinguishing component can also be better extinguished. The lifting mechanism controls the top frame to descend, so that the fire extinguishing component is close to the fire source, the fire extinguishing component is activated, and the rotating mechanism swings left and right to extinguish the fire from all directions.

[0041] Please see Figure 1-2 As shown, the present invention is a safety monitoring device for university laboratories, including a top frame 1, monitoring components 2, an electrical box 5, a fire extinguishing component 6, and a heat dissipation component 7. Multiple monitoring components 2 are provided at the bottom of the top frame 1. The top frame 1 is rotated by a rotating mechanism 3 and raised and lowered by a lifting mechanism 4.

[0042] Among them, such as Figure 3-5 As shown, the monitoring component 2 includes a mounting plate 21, with a camera body 24 fixedly fixed through the center of the mounting plate 21. A support ear 22 is provided on the top of the mounting plate 21. A crossbeam 11 is integrally formed in the middle of the top frame 1.

[0044] Among them, such as Figure 7 As shown, the fire extinguishing assembly 6 includes a U-shaped fire extinguishing pipe 61 and fire extinguishing branch pipes 62. The U-shaped fire extinguishing pipe 61 is fixed to the top of the top frame 1. Multiple fire extinguishing branch pipes 62 are evenly distributed at the bottom of the U-shaped fire extinguishing pipe 61. The fire extinguishing branch pipes 62 are vertically arranged and extend through the through hole 13 on the top frame 1 to the bottom of the top frame 1. The fire extinguishing assembly 6 also includes a main fire extinguishing pipe 63, a fire pump 64, and a fire extinguishing bottle 65. One end of the main fire extinguishing pipe 63 is fixedly connected to the U-shaped fire extinguishing pipe 61, and the other end of the main fire extinguishing pipe 63 is fixedly connected to the outlet of the fire pump 64. The inlet of the fire pump 64 is fixedly connected to the outlet of the fire extinguishing bottle 65. The fire extinguishing bottle 65 is placed inside the lower part of the electrical box 5. The U-shaped fire extinguishing pipe 61 and the fire extinguishing branch pipes 62 are both made of rigid pipes, while the main fire extinguishing pipe 63 is made of flexible pipe.

[0045] When the fire extinguishing component 6 is used, the fire extinguishing pump 64 is activated, and the fire extinguishing material in the fire extinguishing bottle 65 is extracted by the fire extinguishing pump 64. The fire extinguishing material is transported through the fire extinguishing main pipe 63 to the U-shaped fire extinguishing pipe 61, and finally sprayed out from the fire extinguishing branch pipe 62 to extinguish the fire.

[0046] Among them, such as Figure 8As shown, the heat dissipation assembly 7 includes a first heat absorption main pipe 71, a U-shaped heat absorption pipe 72, and a pipe support frame 73. The first heat absorption main pipe 71 is fixed to the top of the crossbeam 11 by two pipe support frames 73. A plurality of U-shaped heat absorption pipes 72 are provided at the bottom of the first heat absorption main pipe 71. The ends of the U-shaped heat absorption pipes 72 pass through the lugs 22 and extend to the top of the camera body 24. The heat dissipation assembly 7 also includes a second heat absorption main pipe 74, a heat dissipation fan 75, and an air outlet pipe 76. One end of the second heat absorption main pipe 74 is fixedly connected to the first heat absorption main pipe 71, and the other end of the second heat absorption main pipe 74 is fixedly connected to the inlet of the heat dissipation fan 75. An air outlet pipe 76 is provided at the outlet of the heat dissipation fan 75. The heat dissipation fan 75 is fixed inside the upper part of the electrical box 5. The first heat absorption main pipe 71 and the air outlet pipe 76 are both made of rigid pipes, while the U-shaped heat absorption pipes 72 and the second heat absorption main pipe 74 are made of flexible pipes.

[0047] When the heat dissipation component 7 is used, the heat dissipation fan 75 is turned on, and the heat is absorbed by the camera body 24 through the U-shaped heat absorption pipe 72. The hot air is then transported through the first heat absorption pipe 71 and the second heat absorption pipe 74, and finally discharged into the environment through the air outlet pipe 76.

[0048] Among them, such as Figure 6 As shown, the rotating mechanism 3 includes a rotating shaft 31, a first bearing seat 32, a first gear 33, a second gear 34, and a first motor 35. The top end of the rotating shaft 31 is fixedly connected to the bottom of the outer end of the top frame 1, and the bottom end of the rotating shaft 31 is rotatably connected to the first bearing seat 32. The first bearing seat 32 is fixed on the top of the L-shaped lifting plate 41. The first gear 33 is fixedly sleeved on the rotating shaft 31. The first gear 33 meshes with the second gear 34. The second gear 34 is fixedly sleeved on the output shaft of the first motor 35. The first motor 35 is fixed on the support platform 42 on the side of the L-shaped lifting plate 41.

[0049] When the rotating mechanism 3 is in use, the first motor 35 is started, which drives the second gear 34 to rotate. The second gear 34 drives the first gear 33 to rotate, which drives the rotating shaft 31 to rotate. The rotating shaft 31 drives the top frame 1 to rotate, thereby enabling the rotation of the monitoring component 2 and the fire extinguishing component 6. When the fire extinguishing component 6 is extinguishing a fire, it can swing left and right through the rotating mechanism 3 to achieve all-round fire extinguishing. When it is necessary to maintain or clean the monitoring component 2, the rotating mechanism 3 can be used to rotate the monitoring component 2 to one side of the experimental platform 8, and then the lifting mechanism 4 can be used to lower it, thereby facilitating the maintenance and cleaning of the monitoring component 2.

[0050] Among them, such as Figure 6As shown, the lifting mechanism 4 includes an L-shaped lifting plate 41, a nut seat 43, and a lead screw 44. The L-shaped lifting plate 41 is fixedly connected to the nut seat 43. The nut seat 43 is movably sleeved on the lead screw 44. The bottom end of the lead screw 44 is fixedly connected to the output shaft of the second motor 45. The top end of the lead screw 44 is rotatably connected to the second bearing seat 46. A guide rod 47 is also fixed between the second bearing seat 46 and the second motor 45. The guide rod 47 passes through the L-shaped lifting plate 41.

[0051] When the lifting mechanism 4 is in use, the second motor 45 is started, which drives the lead screw 44 to rotate. The lead screw 44 drives the nut seat 43 to rise and fall. The nut seat 43 drives the L-shaped lifting plate 41 to rise and fall along the guide rod 47, thereby realizing the lifting and lowering of the top frame 1, the monitoring component 2 and the fire extinguishing component 6. When the fire extinguishing component 6 is extinguishing a fire, the lifting mechanism 4 can control the top frame 1 to descend, so that the fire extinguishing component 6 is closer to the fire source, thereby improving the fire extinguishing effect.

[0052] Among them, such as Figure 10 As shown, the top frame 1 is positioned directly above the experimental platform 8, and the electrical box 5 is positioned to the side of the experimental platform 8.

[0053] One specific application of this embodiment is:

[0054] S1: Adjust the spacing between each monitoring component 2 based on the specifications of the on-site experimental platform 8 and the distribution of the experimental equipment.

[0055] S2: Before students conduct experiments, they identify themselves through the fingerprint recognition module 53 and input which experiment they will be doing on the experimental table 8 through the touch screen 54. Then the controller 57 controls the monitoring component 2 at the corresponding location to run.

[0056] S3: During the experiment, video monitoring is carried out through the camera body 24, and environmental monitoring is carried out through the temperature sensor 25, humidity sensor 26, toxic gas sensor 27 and dust sensor 28. When there is an abnormal situation, the controller 57 controls the buzzer 29 to issue an alarm. The remote teacher can also issue instructions through the speaker 52 to guide students in the experiment and handle emergencies.

[0057] S4: During the operation of the camera body 24, heat dissipation is achieved through the heat dissipation component 7;

[0058] S5: When an emergency occurs and fire needs to be extinguished, the top frame 1 is lowered by the lifting mechanism 4, so that the fire extinguishing component 6 is close to the fire source, the fire extinguishing component 6 is activated, and the rotating mechanism 3 is used to swing left and right to extinguish the fire in all directions.

[0059] S6: When it is necessary to maintain or clean the monitoring component 2, the monitoring component 2 is rotated to one side of the experimental platform 8 by the rotating mechanism 3, and then lowered by the lifting mechanism 4. At this time, the monitoring component 2 can be maintained and cleaned.

[0060] The above are merely preferred embodiments of the present invention and do not limit the present invention. Any modifications, equivalent substitutions, or improvements made to the technical solutions described in the foregoing embodiments, or to some of the technical features, shall fall within the protection scope of the present invention.
