Description

Technical Field

[0001] The present invention relates to the technical field of environmental monitoring, and more specifically, to an environmental monitoring device for a laboratory and a monitoring method thereof. Background Art

[0002] With the continuous development of the economy, my country's energy consumption is increasing, and the phenomenon of energy shortage is becoming more and more serious. In this context, ecological buildings have gradually become popular. Ecological buildings should ensure the applicability of buildings, reflect the care for users, enhance the communication between users and the natural environment, and allow people to live and work in healthy, comfortable and vibrant buildings. It is mainly reflected in creating a good ventilation and convection environment, increasing the daylighting coefficient of the building, ensuring a certain temperature and humidity indoors, creating a good visual environment and sound environment, and establishing a three-dimensional greening system to purify the environment. Among them, the ecological laboratory is a type of ecological building.

[0003] Laboratory animals grow, reproduce and receive experimental treatment in artificial environments. Specific places and their surrounding spaces are the experimental animal environment. In biomedical research, accurate and reliable experimental data must be obtained, and environmental factors must be avoided from adversely affecting the physiological and biochemical activities of animals. In order to create a good experimental animal environment, various monitoring indicators play a vital role in the animal living environment. Air cleanliness and particulate matter pollution are particularly important.

[0004] At present, when it is necessary to monitor the air in the laboratory, it is often necessary to extract the surrounding air and extract the air sample in the laboratory, and monitor the sample to obtain the data of the air sample. However, most of the existing air extraction devices often intelligently monitor the laboratory gas in an area, which has great limitations. As a result, in actual use, the gas monitoring device often needs to be transferred multiple times, resulting in poor convenience. At the same time, after extracting an area, the gas monitoring device is often prone to residual gas samples from the previous area, which makes subsequent monitoring data prone to errors, reducing the accuracy of air environment data monitoring.

[0014] A monitoring method for a laboratory environment monitoring device, the monitoring method comprising the following steps:

[0015] S1. When using the monitoring device, the position of the monitoring device needs to be adjusted according to actual needs. By starting the air pump in reverse, the external gas is extracted and transported to the four sliding sleeves, so that the air pressure in the four sliding sleeves is increased to loosen the adsorption to the ground or wall, and the disassembly work is completed. After the disassembly is completed, the position of the monitoring device is moved by grasping the two handles.

[0016] S2. After the monitoring device is moved to the designated position and positioned, the air pump is started. When the air pump is running, the air in the two first ducts is extracted, and the gas in the four sleeves is quickly extracted through the first ducts. Since the sleeves are in contact with the ground or the wall, there is a continuous negative pressure in the sleeves, which will fix the monitoring shell in the designated position. When the gas in the sleeves is continuously discharged as the air pump is running, the gas in the slide tube will be discharged along the second slide bar, so that the sleeve slides along the surface of the first slide bar. When the sleeve moves to the extreme position, the second slide bar will conflict with the slide tube. At this time, the monitoring shell will be at the same level as the four sleeves.

[0017] S3. When the air pump is running, since the gas in the second three-way and the connecting pipe can be extracted at the same time, and the residual gas in the air monitoring device can be synchronously extracted into the air pump through the third conduit, the air monitoring device can be adjusted through the control panel to observe the monitoring data on the display panel.

[0018] The beneficial effects of the present invention are:

[0019] 1. The present invention provides an air pump, a sleeve, a slide cylinder, a limit plate, a first slide rod and a second slide rod. After the monitoring device is moved to the specified position and positioned, the air pump is started. When the air pump is running, the air in the two first conduits is extracted, and the gas in the four sleeves is quickly extracted through the first conduit. Since the sleeve is in a state of contact with the ground or the wall, and since the sleeve is in a state of continuous negative pressure, the monitoring housing will be fixed at the specified position. When the gas in the sleeve is continuously discharged with the operation of the air pump, the gas in the slide cylinder will be discharged along the second slide rod, so that the sleeve slides along the surface of the first slide rod. When the sleeve moves to the limit position, the second slide rod will conflict with the slide cylinder. At this time, the monitoring housing will be at the same level as the four sleeves. Compared with the existing monitoring device, a vacuum suction cup installation is adopted to prevent the screw from being stripped due to multiple rotations of the bolts. At the same time, the monitoring housing can be easily disassembled during actual use of the monitoring device, avoiding multiple transportation and inconvenience caused by difficult disassembly during use, thereby ensuring the actual use effect of the monitoring device.

[0020] 2. The present invention provides an air pump, a display panel, a second three-way valve and an air monitoring device. When the air pump is running, the gas in the second three-way valve and the connecting pipe can be extracted simultaneously, and the gas remaining in the air monitoring device can be synchronously extracted into the air pump through the third conduit. The air monitoring device is adjusted by the control panel to observe the monitoring data of the display panel. Due to the provision of the one-way valve in the second three-way valve, the gas in the sleeve and the slide cylinder is not easy to enter the air monitoring device along the second three-way valve, which ensures the sealing of the sleeve and the slide cylinder and avoids the situation where ground impurities enter the air monitoring device and cause damage to the air monitoring device. Each time the monitoring location is changed, the residual gas in the air monitoring device can be discharged by installing the monitoring device, thereby reducing the data error caused by residual gas samples in the subsequent data monitoring process and ensuring the accuracy of the monitoring device in monitoring the air environment data.

[0037] A monitoring method for a laboratory environment monitoring device comprises the following steps:

[0038] S1. When using the monitoring device, the position of the monitoring device needs to be adjusted according to actual needs. By starting the air pump 3 in reverse, the external gas is extracted and transported to the four sliding sleeves 12, so that the air pressure in the four sliding sleeves 12 is increased to loosen the adsorption on the ground or wall, and the disassembly work is completed. After the disassembly is completed, the position of the monitoring device is moved by grasping the two handles 29.

[0039] S2. After the monitoring device is moved to the designated position and positioned, the air pump 3 is started. When the air pump 3 is running, the air in the two first ducts 4 is extracted, and the gas in the four sleeves 12 is quickly extracted through the first duct 4. Since the sleeve 12 is in contact with the ground or the wall, the sleeve 12 is in a continuous negative pressure state, and the monitoring housing 1 will be fixed at the designated position. When the gas in the sleeve 12 is continuously discharged as the air pump 3 is running, the gas in the slide 133 will be discharged along the second slide bar 131, so that the sleeve 12 slides along the surface of the first slide bar 10. When the sleeve 12 moves to the extreme position, the second slide bar 131 will conflict with the slide 133. At this time, the monitoring housing 1 will be at the same level as the four sleeves 12.

[0040] S3. When the air pump 3 is running, since the gas in the second three-way valve 15 and the connecting pipe 18 can be extracted simultaneously, and the gas remaining in the air monitoring device can be synchronously extracted into the air pump 3 through the third conduit 19, the air monitoring device 20 can be adjusted through the control panel 26, and the monitoring data of the display panel 27 can be observed.

[0041] By arranging the air pump 3, the sleeve 12, the slide cylinder 133, the limit plate 11, the first slide rod 10 and the second slide rod 131, compared with the existing monitoring device, a vacuum suction cup installation is adopted to prevent the bolt from slipping due to multiple rotations. At the same time, the monitoring device can conveniently disassemble the monitoring shell 1 during actual use, avoiding multiple transportation and inconvenience caused by difficult disassembly during use, thereby ensuring the actual use effect of the monitoring device.

[0042] Because of the provision of the air pump 3, the display panel 27 and the second three-way valve 15, the situation in which ground impurities enter the air monitoring device 20 and cause damage to it is avoided. Therefore, each time the monitoring location is changed, the residual gas inside the air monitoring device 20 can be discharged by simply installing the monitoring device, thereby reducing the data error caused by residual gas samples in the subsequent data monitoring process, and ensuring the accuracy of the monitoring device in monitoring the air environment data.
