DETAILED DESCRIPTION

[0029] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution of the present invention will be clearly and completely described below in conjunction with the embodiments.

[0030] The present invention provides an office area environment monitoring device, such as Figures 1 to 8As shown, it includes a column 1, a monitoring component is arranged on the top of the column 1, and the monitoring component is an environmental monitoring device in the prior art. A circular ring 3 is fixedly connected to the outer side of the column 1 through a ring plate 2. A circular groove is provided on the top of the circular ring 3, and a protective sleeve 4 is fixedly connected to the bottom wall of the circular groove. The protective sleeve 4 is a plastic film, and an elastic ring 5 is fixedly connected to the top of the protective sleeve 4. The protective sleeve 4 is stored in the circular groove in a compressed and folded state. The elastic ring 5 is made of rubber, and a supporting component for supporting it is arranged on the inner side of the elastic ring 5. A pair of side plates are symmetrically fixedly installed on the outer side of the circular ring 3. A cover plate 6 is rotatably installed between the two cover plates 6, and rubber sheets are provided at the opposite ends of the two cover plates 6. A closed ring 7 is provided at the bottom of the support assembly, and a rubber pad 8 is provided at the bottom of the circular ring 3. A round rod 26 cooperating with the elastic ring 5 is provided on the top of the monitoring assembly. When the elastic ring 5 is not opened, its inner diameter is smaller than the outer diameter of the round rod 26. A baffle 38 is provided on the external fixed sleeve of the column 1, and a sealing ring is provided on the outer side of the baffle 38. The sealing ring is fitted with the cover plate 6. A power cord 36 is provided on the monitoring assembly, and the power cord 36 passes through the column 1 and extends to its outside. The power cord 36 passes through the column 1 and is coated with waterproof glue.

[0031] When in use, the monitoring component is powered by connecting to an external socket through a power cord 36, and environmental monitoring is performed through the monitoring component. The column 1 is fixed on the ground. When a flood disaster occurs, the water level rises to the bottom of the ring plate 2, triggering the support component to rise with the elastic ring 5 to push open the cover plate 6. At this time, the protective cover 4 is unfolded, and the support component rises with the closed ring 7 and finally collides with the rubber pad 8. Then the support component cancels the support for the elastic ring 5, and then the elastic ring 5 shrinks and is finally sleeved on the outside of the round rod 26. At this time, the protective cover 4 wraps the entire monitoring component, and cooperates with the closed ring 7, the ring plate 2, and the circular ring 3 to close the entire monitoring component, so that when the subsequent water level submerges the monitoring component, the monitoring component can be isolated from water to prevent the monitoring component from being soaked.

[0032] like Figure 1 , Figure 2 , Figure 3 , Figure 7As shown, the support assembly includes a vertical plate 9, the top of the vertical plate 9 extends to the inside of the circular ring 3, the top of the vertical plate 9 is fixedly connected to a limiting block 15, a support plate 10 is provided above the vertical plate 9, and a limiting block 11 that fits the support plate 10 is fixedly installed on the top of the limiting block 15, a mounting plate 12 is symmetrically fixedly installed on the upper outer side of the vertical plate 9, and a rotating shaft 14 is fixedly sleeved on the lower part of the support plate 10, and both ends of the rotating shaft 14 are respectively rotatably connected to the mounting plates 12 on both sides, and both ends of the rotating shaft 14 extend to the outside of the mounting plate 12 and are sleeved with a first torsion spring 13, and the two ends of the first torsion spring 13 are respectively fixedly connected to the mounting plate 12 and the rotating shaft 14, a pulling assembly for pulling the support plate 10 to make it vertical is provided on the outer side of the support plate 10, a slot 16 that cooperates with the elastic ring 5 is provided on the side of the support plate 10 close to the elastic ring 5, and a lifting assembly for driving them to rise is provided on the outer side of the support plate 10 and the vertical plate 9.

[0033] When the water level reaches the bottom of the ring plate 2, the lifting assembly rises with the support plate 10, the vertical plate 9, and the closed ring 7. As the support plate 10 rises, the matching card slot 16 rises with the elastic ring 5 to unfold the protective cover 4. Finally, the closed ring 7 contacts the rubber pad 8 that contacts the circular ring 3. Then the pulling assembly cancels the pulling on the support plate 10. The torsionally deformed first torsion spring 13 releases the force to rotate the rotating shaft 14 and the support plate 10 toward the direction close to the round rod 26, so that the support plate 10 tilts. The elastic ring 5 in the deformed state relies on its own restoring force to disengage from the card slot 16 and finally from the support plate 10, so that the opening of the elastic ring 5 is reduced, and finally it is sleeved outside the round rod 26, so that the monitoring assembly is isolated.

[0034] like Figures 3 to 6 As shown, the pulling assembly includes a pull rope 17, one end of which is fixedly connected to the upper part of the support plate 10 near the elastic ring 5, a connecting channel is provided at the top of the limiting block 11 and the inside of the vertical plate 9, a rotating groove connected to the channel is provided at the outer lower part of the vertical plate 9, a round shaft is rotatably installed in the rotating groove, a pressure plate 18 is fixedly sleeved on the outside of the round shaft, and a second torsion spring 19 is sleeved on both ends of the round shaft, and the two ends of the second torsion spring 19 are respectively fixedly connected to the pressure plate 18 and the inner wall of the rotating groove, the other end of the pull rope 17 passes through the channel and is fixedly connected to the lower part of the pressure plate 18, and the torsion of the second torsion spring 19 is greater than the torsion of the first torsion spring 13.

[0035] As the vertical plate 9 rises, the mounting plate 12, the rotating shaft 14, the supporting plate 10, the circular shaft, the pressing plate 18 and the closed ring 7 rise. When the pressing plate 18 contacts the bottom of the circular ring 3, it is squeezed and rotates into the rotating groove, causing the pull rope 17 to loosen. The torsionally deformed first torsion spring 13 releases its force and rotates the rotating shaft 14 and the supporting plate 10 toward the direction close to the circular rod 26.

[0036] like Figure 3As shown, the lifting assembly includes support plates 10 equidistantly arranged on both sides and teeth 20 on the inner side of the vertical plate 9, the inner side of the circular ring 3 is symmetrically provided with openings connected to the inside of the ring groove, a horizontal plate corresponding to the opening is fixedly installed on the inner side of the circular ring 3, a first gear 21 meshing with the teeth 20 is rotatably installed on the horizontal plate, a fixed plate is fixedly installed on the top of the ring plate 2, a second gear 22 cooperating with the first gear 21 is rotatably installed on the inner side of the fixed plate, a motor 23 is fixedly installed on one side of the fixed plate, one end of the output shaft of the motor 23 is fixedly connected to the middle part of the second gear 22, a liquid level sensor 25 is provided at the bottom of the ring plate 2, a controller 24 cooperating with the liquid level sensor 25 for controlling the motor 23 is provided at the top of the ring plate 2, the controller 24 is a PLC controller, and a first battery for powering the controller 24, the liquid level sensor 25 and the motor 23 is provided inside the ring plate 2, which is not shown in the figure.

[0037] When the water level reaches the bottom of the ring plate 2, the liquid level sensor 25 is triggered. The liquid level sensor 25 cooperates with the controller 24 to control the output shaft of the motor 23 to rotate with the second gear 22, and cooperates with the first gear 21 and the teeth 20 to lift the support plate 10, the rotating shaft 14, the mounting plate 12, and the vertical plate 9. During the rising process, since the torsion of the second torsion spring 19 is greater than the torsion of the first torsion spring 13, the torsionally deformed first torsion spring 13 cannot release the force. Therefore, during the rising process, the support plate 10 remains in a vertical state, thereby realizing the rising of the support plate 10 and the vertical plate 9. When the closed ring 7 conflicts with the rubber pad 8 at the bottom of the circular ring 3, the motor 23 stops.

[0038] like Figure 7 As shown, the outer side of the round rod 26 is symmetrically sleeved with a ring sleeve 27, and the opposite side of the two ring sleeves 27 is provided with a first electromagnet 30, and the magnetic poles of the opposite first electromagnets 30 are opposite. A placement groove is opened on the top of the round rod 26, and a second battery 28 and a remote controller 37 are arranged in the placement groove. A cover is provided on the top of the placement groove. A wire hole connected to the placement groove and the outside is provided in the round rod 26, and a wire 29 is provided in the wire hole. The two ends of the wire 29 are respectively connected to the second battery 28 and the corresponding first electromagnet 30. The remote controller 37 cooperates with the controller 24, and an inclined surface is provided at the bottom of the ring sleeve 27.

[0039] The ring sleeve 27 is specifically a semi-annular plate-shaped component. The two energized first electromagnets 30 attract each other, so that a pair of ring sleeves 27 are arranged outside the round rod 26 to protect it, preventing dust from sticking to the round rod 26 and affecting the tight contact between the elastic ring 5 and the round rod 26, thereby ensuring the airtightness of the combination between the elastic ring 5 and the round rod 26. When the motor 23 is started, the liquid level sensor 25 controls the first electromagnet 30 to cut off power through the remote controller 37, so that it loses its magnetism. Under the action of gravity, the two ring sleeves 27 cooperate with the inclined surface to detach from the round rod 26 and fall below the round rod 26, so that the subsequent elastic ring 5 can be combined with the clean round rod 26.

[0040] like Figure 7 As shown, the outer sleeve of the round rod 26 is provided with a pressing ring 31, the top of the pressing ring 31 is fixedly connected to the top wall of the round rod 26 through a spring 34, the top of the pressing ring 31 is located at the top of the ring sleeve 27 and fits therewith, and the top of the pressing ring 31 is provided with a locking assembly for locking it, the pressing ring 31 is fixedly connected to the top wall of the round rod 26 through a telescopic sleeve 35, and the bottom of the round rod 26 is provided with a platform.

[0041] When in use, when the elastic ring 5 is separated from the support plate 10 and shrinks toward the round rod 26, due to the uneven distribution of rainwater on the protective cover 4, it will cause different degrees of pulling on the elastic ring 5, so that when the elastic ring 5 is sleeved outside the round rod 26, it cannot be in a horizontal state, and one side will be higher than the other side, resulting in the elastic ring 5 and the round rod 26 cannot be tightly contacted, affecting the sealing. Therefore, when the elastic ring 5 is sleeved outside the round rod 26, the motor 23 stops for 10S, and the locking assembly cancels the lock on the pressure ring 31. The compressed spring 34 releases the force and drives the pressure ring 31 down, so that the elastic ring 5 is driven downward, and finally the elastic ring 5 contacts the bottom platform of the round rod 26, and then the pressure ring 31 squeezes the elastic ring 5 to deform it toward the periphery, so that it can be more in contact with the round rod 26, thereby improving the airtightness and preventing the elastic ring 5 from having one side higher than the other side.

[0042] like Figure 7 As shown, the locking assembly includes an iron rod 32 fixedly connected to the top of the pressure ring 31 , a second electromagnet 33 corresponding to the iron rod 32 is provided on the top wall of the round rod 26 , and the second battery 28 supplies power to the second electromagnet 33 .

[0043] When the motor 23 stops for 10 seconds, the controller 24 sends a command to the remote controller 37 to control the second electromagnet 33 to be powered off to lose its magnetism, and then the compressed spring 34 releases its force to bring the pressure ring 31 down.

[0044] The method for monitoring using the above-mentioned office area environment monitoring device comprises the following steps:

[0045] S1. When in use, the monitoring component is powered by connecting the power cord 36 to an external socket, and the monitoring component is used to monitor the environment, and the column 1 is fixed on the ground;

[0046] S2. When a flood disaster occurs, the water level rises to the bottom of the ring plate 2, triggering the support assembly to rise with the elastic ring 5 to push open the cover plate 6. At this time, the protective cover 4 is unfolded, and the support assembly rises with the closed ring 7 and finally conflicts with the rubber pad 8. Then the support assembly cancels the support for the elastic ring 5;

[0047] S3, the elastic ring 5 is then shrunk and finally sleeved outside the round rod 26. At this time, the protective cover 4 wraps the entire monitoring assembly, and cooperates with the closing ring 7, the ring plate 2, and the circular ring 3 to seal the entire monitoring assembly.

[0048] Working principle: When in use, the monitoring component is powered by connecting to an external socket through a power cord 36, and the environmental monitoring is performed through the monitoring component. The column 1 is fixed on the ground. When a flood disaster occurs, the water level rises to the bottom of the ring plate 2, triggering the liquid level sensor 25. The liquid level sensor 25 cooperates with the controller 24 to control the output shaft of the motor 23 to rotate with the second gear 22, and cooperates with the first gear 21 and the teeth 20 to lift the support plate 10, the rotating shaft 14, the mounting plate 12, and the vertical plate 9. In the process of rising, since the torsion of the second torsion spring 19 is greater than the torsion of the first torsion spring 13, the torsional deformation The first torsion spring 13 cannot release the force, so the support plate 10 remains in a vertical state during the rising process, and the closed ring 7 rises with the vertical plate 9. As the support plate 10 rises, the matching card slot 16 rises with the elastic ring 5 to unfold the protective cover 4, and finally the closed ring 7 conflicts with the rubber pad 8 that conflicts with the circular ring 3. As the vertical plate 9 rises, the mounting plate 12, the rotating shaft 14, the support plate 10, the circular shaft, the pressing plate 18, and the closed ring 7 rise. When the pressing plate 18 conflicts with the bottom of the circular ring 3, it is squeezed and rotated into the rotating groove, making the pull rope 17 loose, and the torsionally deformed first torsion spring 13 releases its effect. The force drives the rotating shaft 14 and the support plate 10 to rotate in the direction close to the round rod 26, so that the support plate 10 is tilted, and the elastic ring 5 in the deformed state relies on its own restoring force to disengage from the card slot 16, and finally disengage from the support plate 10, so that the opening of the elastic ring 5 is reduced, and finally it is sleeved outside the round rod 26, so that the monitoring component is isolated. At this time, the protective sleeve 4 wraps the entire monitoring component, and cooperates with the closing ring 7, the ring plate 2, and the circular ring 3 to close the entire monitoring component, so that when the subsequent water level submerges the monitoring component, the monitoring component can be isolated from water to prevent the monitoring component from being damaged by soaking; the ring sleeve 27 is specifically a semi-annular plate structure The two first electromagnets 30 that are energized attract each other, so that a pair of ring sleeves 27 are sleeved outside the round rod 26 to protect it, so as to prevent dust from sticking to the round rod 26 and affecting the tight contact state between the elastic ring 5 and the round rod 26, and ensure the tightness of the combination between the elastic ring 5 and the round rod 26. When the motor 23 is started, the liquid level sensor 25 controls the first electromagnet 30 to be powered off through the remote controller 37, so that it loses its magnetism. Under the action of gravity, the two ring sleeves 27 cooperate with the inclined surface to separate from the round rod 26 and fall below the round rod 26, so that the subsequent elastic ring 5 can be combined with the clean round rod 26;When in use, when the elastic ring 5 is separated from the support plate 10 and shrinks toward the round rod 26, the uneven distribution of rainwater on the protective cover 4 will cause different degrees of pulling on the elastic ring 5, so that when the elastic ring 5 is sleeved outside the round rod 26, it cannot be in a horizontal state, and one side will be higher than the other side, resulting in the elastic ring 5 and the round rod 26 not being able to contact tightly, affecting the sealing performance. Therefore, after the elastic ring 5 is sleeved outside the round rod 26, the motor 23 stops for 10S, and the controller 24 sends a command to the remote controller 37 to control the second electromagnet 33 to be powered off to lose its magnetism, and then the compressed spring 34 releases the force to bring the pressure ring 31 down, so that the elastic ring 5 is driven downward, and finally the elastic ring 5 contacts the bottom platform of the round rod 26, and then the pressure ring 31 squeezes the elastic ring 5 to deform toward the periphery, so that it can contact the round rod 26 more, improve the sealing performance, and prevent the elastic ring 5 from having one side higher than the other side. ;

[0049] The above embodiments are only used to illustrate the technical solutions of the present invention, rather than to limit them.
