Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and in particular to a plant indoor environment monitoring device. Background Art

[0002] Indoor environmental monitoring refers to the process of real-time or regular monitoring and evaluation of building air quality, temperature, humidity, light and other parameters. This monitoring aims to ensure that the indoor environment meets relevant health, comfort and safety standards to protect the health and comfort of people inside the building.

[0003] Indoor environmental monitoring usually involves the following aspects:

[0004] Air quality monitoring: including monitoring of harmful gases, particulate matter, volatile organic compounds (VOCs), gas concentrations, etc.

[0005] Temperature and humidity monitoring: Monitor the temperature and humidity of indoor air to ensure comfort and health.

[0006] Light monitoring: Measures light levels in a room to ensure it is adequate but not too bright.

[0007] Noise monitoring: Monitor the indoor noise level to ensure it is within an acceptable range.

[0008] Other parameter monitoring: such as air circulation, operation of air purification equipment, etc.

[0009] Through indoor environmental monitoring, problems with indoor environmental quality can be discovered and resolved in a timely manner, improving the comfort and safety of living and working environments.

[0010] The existing announcement number CNB discloses an indoor environment data collection device that can be installed in an integrated manner, which relates to the field of indoor monitoring technology. A controller and a display screen are fixedly installed on the upper end of the main shell by bolts, and a temperature and humidity sensor, an infrared sensor, a smoke sensor and a panoramic camera are fixedly installed on the rotating seat by bolts. A built-in power supply, a network card and a memory are installed inside the main shell. The network card and the built-in power supply are connected to external network cables and cables through a terminal block, and the controller is electrically connected to the display screen, the temperature and humidity sensor, the infrared sensor, the smoke sensor, the panoramic camera, the built-in power supply, the network card and the memory through wires. The controller is an stm series single-chip microcomputer, and the drive motor is a DC stepping motor. The built-in power supply is a rechargeable lithium battery pack, and the display screen is a liquid crystal display.

[0011] However, there are the following problems in the above prior art:

[0012] When monitoring the temperature, humidity, smoke and dust concentration of the air, since the sensors are directly exposed indoors, the temperature, humidity, smoke and dust concentrations in different locations in the room have different concentrations, which will lead to errors in the monitoring data. In addition, the monitoring depends entirely on the free flow of air, which can easily lead to inaccurate monitoring.

[0013] It can only monitor the internal environment but cannot monitor whether the exhaust gas meets the standards, which makes the device too single in function.

[0014] Therefore, a plant indoor environment monitoring device is needed. Summary of the invention

[0015] In order to solve all or part of the above problems, the present invention aims to provide a factory indoor environment monitoring device to solve the problems in the above background technology that the monitored data may have errors and the device has too single function.

[0016] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a plant indoor environment monitoring device, comprising a central tube and an air inlet pipe installed at the lower side of the central tube, air guide covers are arranged on both sides of the central tube, a protective piece is arranged at the upper end of the air guide cover, a monitoring component is arranged at the middle part of the inner side of the protective piece, an input end of the monitoring component is connected to an output end of the air guide cover, and a support frame is installed at the outer side of the protective piece;

[0017] The monitoring component includes a sealing cover and an exhaust protective cover installed in the middle of the output end of the sealing cover. A fan is arranged in the middle of the inner side of the exhaust protective cover, a sleeve is arranged on the inner side of the sealing cover at the lower end of the fan, a monitoring assembly is arranged on the inner side of the sleeve, and the monitoring assembly includes a central column and an inner monitoring head arranged at one end of the central column, an outer monitoring head is arranged at the other end of the central column, and multiple groups of filter assemblies are arranged on the inner side of the sleeve located on the outside of the monitoring assembly, the inner monitoring head is located at the input end of the filter assembly, and the outer monitoring head is located at the output end of the filter assembly.

[0018] Furthermore, there are four inner monitoring heads arranged in a cross shape, which are a temperature sensor, a humidity sensor, a smoke sensor and a dust sensor in sequence; and there are two outer monitoring heads arranged in a straight line, which are a smoke sensor and a dust sensor in sequence.

[0019] Furthermore, a flow diversion component is also arranged inside the input end of the sleeve, and the flow diversion component includes a support plate and a flow diversion plate arranged at the lower end of the support plate, and four flow diversion plates are arranged in a cross shape.

[0020] Furthermore, a slotted sheet is provided at the upper end of the support sheet, and four slotted sheets are also provided in a cross shape, and a filter assembly is placed between adjacent slotted sheets, and the filter assembly includes a storage box and a multi-layer filter element provided inside the storage box.

[0021] Furthermore, a vibration component is provided on one side of the central column, and the vibration component includes a rotating rod and a knocking plate fixedly arranged on the rotating rod. Torsion springs are also fixedly arranged at both ends of the rotating rod, and multiple vibration plates are arranged on the outside of the storage box.

[0022] Furthermore, the protective member includes a protective frame and a connecting plate fixedly arranged at the lower end of the protective frame, and a shielding net is arranged on the outer side of the protective frame.

[0023] Furthermore, a transmission assembly is provided at the upper end of the monitoring assembly, and the transmission assembly includes a center bearing, an extension rod is provided on the outer ring of the center bearing, a transmission gear is movably provided on the lower side of one end of the extension rod away from the outer ring of the center bearing, a sleeve ring is provided on the outer side of the transmission gear, teeth are provided on the inner side of the sleeve ring, the transmission gear is meshingly connected with the teeth, and the transmission gear is also meshingly connected with a driving gear provided on the lower side of the inner ring of the center bearing, a support rod is provided on the outer side of the sleeve ring, and the end of the support rod away from the sleeve ring is fixedly connected to the sleeve, the upper end of the center bearing is connected to the middle part of the fan, and the lower end of the driving gear is fixedly connected to the middle part of the upper end of the monitoring assembly, a plurality of teeth are provided, and they occupy one-fourth of the sleeve ring, and the number of teeth is one-fourth of the number of external teeth of the transmission gear, and the number of external teeth of the driving gear is the same as that of the transmission gear.

[0024] Compared with the prior art, the present invention has the following beneficial effects:

[0025] The present invention proposes a factory indoor environment monitoring device. When the fan is started, the air inside the factory enters into the center pipe from the air inlet pipe, and then enters into the input end of the sleeve through the air guide cover. At this time, the internal monitoring head monitors the air. The air concentration is increased by concentrating the air inside the factory.

The air is filtered through the filter component, and then the smoke and dust emissions are monitored after being discharged to see if they meet the standards. Synchronous environmental monitoring and exhaust gas compliance monitoring can be achieved, thereby improving the versatility of monitoring.

[0026] The present invention proposes a factory indoor environment monitoring device. After the fan is started, it will simultaneously drive the outer ring of the center bearing to rotate, and the center bearing will drive the extension rod to rotate and then drive the transmission gear to rotate. When the transmission gear is meshed with the teeth, it will rotate, and then drive the drive gear to rotate, and only rotate a quarter of a turn. At this time, the outer monitoring head and the inner monitoring head also only rotate a quarter of a turn. With the continuous rotation of the outer monitoring head and the inner monitoring head, the air at different positions in the space inside the casing can be monitored, thereby improving the monitoring uniformity and further improving the monitoring accuracy. Moreover, when the transmission gear is not meshed with the teeth, the driving gear will no longer rotate, which can give the outer monitoring head and the inner monitoring head a monitoring time gap to ensure the monitoring effect. At the same time, it can also be used as a comparative judgment of whether the filter component is blocked to avoid the problem of filtering problems caused by complete blockage.

DETAILED DESCRIPTION

[0038] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0039] like Figure 1-Figure 2 As shown, a factory indoor environment monitoring device includes a central tube 1 and an air intake pipe 11 installed on the lower side of the central tube 1, a plurality of air intake pipes 11 are provided, air guide covers 2 are provided on both sides of the central tube 1, the two air guide covers 2 are respectively installed on the walls on both sides of the factory, and the central tube 1 is located inside the factory and connected with the two air guide covers 2, a protective member 4 is provided on the upper end of the air guide cover 2, a monitoring component 3 is provided in the middle of the inner side of the protective member 4, the input end of the monitoring component 3 is connected with the output end of the air guide cover 2, a support frame 5 is installed on the outer side of the protective member 4, the support frame 5 installs the protective member 4 on the outer side of the factory, the protective member 4 includes a protective frame 41 and a connecting plate 42 fixedly arranged at the lower end of the protective frame 41, and a shielding net 43 is provided on the outer side of the protective frame 41 for protecting the monitoring component 3.

[0040] like Figure 2-Figure 4As shown, the monitoring component 3 includes a sealing cover 31 and an exhaust protective cover 32 installed in the middle of the output end of the sealing cover 31. Two groups of exhaust protective covers 32 are provided. Fans 33 are provided in the middle of the inner sides of the two groups of exhaust protective covers 32. A sleeve 34 is provided on the inner side of the sealing cover 31 at the lower end of the fan 33. A monitoring component 35 is provided on the inner side of the sleeve 34. The monitoring component 35 includes a central column 351 and an inner monitoring head 352 provided at one end of the central column 351. An outer monitoring head 353 is provided at the other end of the central column 351. Four inner monitoring heads 352 are provided in a cross shape, which are a temperature sensor, a humidity sensor, a flue gas sensor and a dust sensor in sequence. Two outer monitoring heads 353 are provided in a straight line shape, which are a flue gas sensor and a dust sensor in sequence. Multiple groups of filter components 37 are provided on the inner side of the sleeve 34 located on the outer side of the monitoring component 35. The inner monitoring head 352 is located at the input end of the filter component 37, and the outer monitoring head 353 is located at the output end of the filter component 37.

[0041] Specifically, the fan 33 is started, so that the air inside the factory enters the center tube 1 from the air inlet pipe 11, and enters the input end of the sleeve 34 through the air guide cover 2. At this time, the internal monitoring head 352 monitors the air. Because the input end is filtered, the output flow rate is less than the flow rate of the air inlet. Therefore, the air concentration is increased by concentrating the air inside the factory. At this time, when the internal monitoring head 352 detects that one or more of the air temperature, humidity, flue gas and dust volume exceeds the standard, an alarm will be issued to ensure the monitoring accuracy and avoid false alarms caused by excessive local concentration. The air is filtered through the filter component 37, and then the flue gas and dust emissions are monitored after discharge to see if they meet the standards, thereby achieving synchronous environmental monitoring and exhaust gas compliance monitoring, thereby improving the versatility of monitoring.

[0042] like Figure 4 and Figure 7As shown, a transmission assembly 38 is disposed at the upper end of the monitoring assembly 35, and the transmission assembly 38 includes a central bearing 381. The upper end of the outer ring of the central bearing 381 is coaxially fixedly connected to the middle of the fan 33. An extension rod 382 is also fixedly disposed on the outer side of the outer ring of the central bearing 381. A transmission gear 383 is movably disposed on the lower side of one end of the extension rod 382 away from the outer ring of the central bearing 381. A collar 384 is disposed on the outer side of the transmission gear 383. A tooth 385 is disposed on the inner side of the collar 384. A plurality of teeth 385 are disposed, and the number of teeth 385 occupies 100% of the collar 384. The transmission gear 383 is meshed with the teeth 385. The transmission gear 383 is also meshed with the driving gear 386 arranged on the lower side of the inner ring of the center bearing 381. The driving gear 386 has the same number of external teeth as the transmission gear 383. The lower end of the driving gear 386 is fixedly connected to the middle part of the upper end of the monitoring component 35. A support rod 387 is arranged on the outer side of the ring 384. The end of the support rod 387 away from the ring 384 is fixedly connected to the sleeve 34.

[0043] The center bearing 381 is an existing conventional bearing, which is composed of an inner ring, balls and an outer ring. The outer ring is connected to one end of the fan 33 and the extension rod 382, ​​while the lower end of the inner ring is fixedly connected to the driving gear 386.

[0044] Specifically, after the fan 33 is started, it will simultaneously drive the outer ring of the center bearing 381 to rotate, and the center bearing 381 will drive the extension rod 382 to rotate and then drive the transmission gear 383 to rotate. When the transmission gear 383 is engaged with the teeth 385, it will rotate, and then drive the drive gear 386 to rotate, and only rotate a quarter of a turn. At this time, the outer monitoring head 353 and the inner monitoring head 352 also only rotate a quarter of a turn. With the continuous rotation of the outer monitoring head 353 and the inner monitoring head 352, the air at different positions in the space inside the casing 34 can be monitored, thereby improving the monitoring uniformity and further improving the monitoring accuracy. Moreover, when the transmission gear 383 is not engaged with the teeth 385, the drive gear 386 no longer rotates, which can give the outer monitoring head 353 and the inner monitoring head 352 a monitoring time gap to ensure the monitoring effect. At the same time, it can also be used as a comparative judgment of whether the filter component 37 is blocked to avoid the problem of filtering problems caused by complete blockage.

[0045] like Figure 4 As shown, a diverter assembly 36 is also provided on the inner side of the input end of the sleeve 34. The diverter assembly 36 includes a support sheet 361 and a diverter sheet 362 arranged at the lower end of the support sheet 361. Four diverter sheets 362 are arranged in a cross shape. The support sheet 361 is provided with air holes. A slotted sheet 363 is also provided on the upper end of the support sheet 361. Four slotted sheets 363 are also arranged in a cross shape, and a filter assembly 37 is placed between adjacent slotted sheets 363.

[0046] Specifically, the air intake end and the filter end are divided into four groups. When the data detected by the internal monitoring head 352 after rotation is abnormal between one group of adjacent diverter plates 362 and the difference with other groups is too large, and at the same time, the monitoring data of the external monitoring head 353 between the slot plates 363 corresponding to the diverter plates 362 does not change or tends to the external air data, it means that the filter assembly 37 between the corresponding slot plates 363 is seriously blocked. At this time, the staff is reminded to replace the filter assembly 37 to ensure the filtering effect and achieve the effect of real-time monitoring.

[0047] like Figure 3-Figure 5 As shown, the filter assembly 37 includes a storage box 371 and a multi-layer filter element 372 arranged on the inner side of the storage box 371. The multi-layer filter element 372 may include a filter cotton filter layer, a glass fiber paper filter layer, a ceramic adsorption filter layer, and a HEPA layer, etc. The air flowing from the inside of the storage box 371 is filtered by the filter element 372 to meet the emission standards, which is convenient for replacement.

[0048] like Figure 4 , Figure 8-Figure 9 As shown, a vibration component 39 is also provided on one side of the central column 351, and the vibration component 39 includes a rotating rod 391 and a knocking plate 392 fixedly arranged on the rotating rod 391. Torsion springs 393 are also fixedly arranged at both ends of the rotating rod 391. A plurality of vibration plates 373 are provided on the outside of the storage box 371. When the central column 351 rotates, the rotating rod 391 is driven to rotate, thereby causing the knocking plate 392 to rotate. When the knocking plate 392 contacts the vibration plate 373, the torsion spring 393 will be twisted. When the knocking plate 392 is separated from the vibration plate 373, the knocking plate 392 is reset under the reset effect of the torsion spring 393, and knocks on the next vibration plate 373, causing the vibration plate 373 to vibrate and then the storage box 371 to vibrate, thereby causing the filter element 372 to vibrate, so that the dust blocked in the mesh of the filter element 372 is vibrated to loosen or fall off, thereby increasing the service life of the filter element 372.

[0049] It should be noted that, in the description of the present application, it should be understood that the terms "length", "thickness", "inside", "outside", "axial", "radial", etc., indicating orientations or positional relationships are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0050] In addition, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprises", or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article, or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article, or apparatus.

[0051] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical scheme and inventive concept of the present invention within the technical scope disclosed by the present invention, which should be covered by the protection scope of the present invention.
