Description

Technical Field

[0001] The invention relates to a cylinder regulating device, in particular to an automatic regulating device suitable for an atmospheric dust suppression cylinder, belonging to the technical field of dust suppression cylinders. Background Art

[0002] Atmospheric dry and wet deposition is a crucial link in the migration of elements or pollutants within the environment. It is closely linked to environmental protection and provides a basis for studying the changing patterns and trends of air quality and for forecasting and predicting air pollution. In all projects investigating the causes of arable land soil pollution, atmospheric deposition monitoring points are deployed for long-term observations to analyze the accumulation risk of heavy metals such as cadmium in arable land soils. The amount and concentration of dry and wet deposition vary across seasons, so sampling generally occurs over a period of at least one year, with samples collected on a quarterly basis.

[0003] For example, the Chinese utility model patent with the announcement number CN202612991U discloses a detachable dust reduction cylinder bracket and the Chinese utility model patent with the announcement number CN217384889U discloses a bracket for atmospheric dry and wet dust reduction sampling cylinders. Both of the above patents use brackets to fix the dust reduction cylinders. For example, the Chinese utility model patent with the announcement number CN217654837U discloses an atmospheric dust collection device and the Chinese utility model patent with the announcement number CN218766208U discloses a bird-proof and fixed ambient air sampling dust reduction cylinder. The above two patents disclose the use of dust-proof nets and bird-proof parts to prevent bird droppings, leaves and other impurities from falling into the dust reduction cylinder. However, in actual use, bird droppings, leaves and other impurities will remain on the filter net. The plate will affect the subsequent precipitation materials in the air entering the dust suppression cylinder. At the same time, in technical fields such as surveying and sampling, due to the large difference in rainfall between the south and the north, different regions have different requirements for the size of dust suppression cylinders. In order to facilitate sampling work in the southern areas with heavy rainfall, sedimentation cylinders with large volumes and openings are generally required. However, we found in actual use that such large-volume sedimentation cylinders are very unfavorable for actual operations, because the daily demand for such cylinders is small, and generally need to be customized, and most cylinders will not be used again after being used once. When used in the north, due to the small amount of rainfall, sedimentation cylinders with smaller openings are generally required. Therefore, the above-mentioned sedimentation cylinders with large volumes and openings cannot be used and need to be purchased again, resulting in increased costs and waste.

[0004] Moreover, for example, the Chinese invention patent with the announcement number CN118566084A discloses an atmospheric dust suppression cylinder that can automatically replenish liquid. Although it discloses the use of a liquid storage tank to automatically replenish liquid for the dust suppression cylinder so that the liquid in the dust suppression cylinder is maintained within a certain range, the structure is relatively complex. When the rainfall in the rainy season is large, the water content in the cylinder increases and the ethylene glycol is diluted. In the above case, the regulation of the ethylene glycol content in the liquid cannot be met. SUMMARY

[0005] The technical problem solved by the present application is to provide an automatic adjusting device for an atmospheric dust cylinder, which can change the opening diameter of the cover body by changing the height of the mounting table and moving the middle part of the cover body upward or downward under the push of the connecting piece, can be reused, reduces the use cost, and avoids waste.

[0028] To facilitate understanding of the present application, the present application will be described more fully below with reference to the accompanying drawings. The accompanying drawings provide embodiments of the present application. However, the present application may be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to make the disclosure of the present application more thorough and comprehensive.

[0029] See also Figure 1 -9. The present invention provides a technical solution:

[0030] Example 1

[0031] An automatic adjustment device for an atmospheric dust suppression cylinder comprises a cover 1 and a hood 2 disposed within the cover 1. The cover 1 is snap-fitted to the top of the dust suppression cylinder. The hood 2 is an annular structure made of elastic material. A mounting platform 3 is disposed within the cover 1. A connector is provided between the mounting platform 3 and the hood 2. By changing the height of the mounting platform 3, the middle portion of the hood 2 is moved upward or downward under the push of the connector, thereby changing the opening diameter of the hood 2. The cross-section of the upper portion of the mounting platform 3 is an isosceles trapezoidal structure.

[0032] like Figure 1As shown in FIG-2, the inner wall of the cover body 1 is provided with an annular groove 6. When the cover body 2 is not under force, the bottom of the inner wall of the annular groove 6 and the upper surface of the cover body 2 are located at the same horizontal plane. The outer peripheral surface of the cover body 1 is provided with a plurality of drainage holes 7 connected with the annular groove 6. Figure 3 As shown, the mounting platform 3 is moved upward so that the cover body 2 is in a frustum shape, and the radius of the opening of the cover body 2 is 15 cm. At this time, when it rains, the rainwater that does not fall into the dust suppression tank through the opening of the cover body 2 can be completely discharged through the drainage hole 7 under the guidance of the inclined surface of the upper surface of the cover body 2;

[0033] The inner wall of the cover body 1 is provided with an annular cover 8, and an annular cavity is formed between the outer peripheral surface of the annular cover 8 and the inner wall of the annular groove 6. A retaining ring 9 which can move up and down is provided in the annular cavity. Figure 4 As shown, the mounting platform 3 moves downward to make the cover body 2 funnel-shaped. At this time, the effective radius of the dust suppression cylinder for collecting rainwater is 40CM, with the inner circle radius of the cover body 1 being used as the dust suppression cylinder. At this time, the lower surface of the retaining ring 9 fits with the bottom of the inner wall of the annular groove 6, which can prevent the rainwater entering the cover body 1 from being discharged through the drainage hole 7.

[0034] like Figure 5 As shown, two connecting plates 10 are connected to each other on both sides of the retaining ring 9 through a rod body. The connecting plates 10 are located on the outside of the cover body 1. The bottom of the connecting plate 10 is connected to the mounting platform 3 through two connecting rods 11. In order to limit the position of the retaining ring 9, a connecting ring 13 is provided in the middle of the two connecting plates 10. A locking bolt 14 is threadedly connected to the connecting ring 13. In this embodiment, the number of the locking bolts 14 is at least two. A plurality of through grooves corresponding to the rod body and the connecting rod 11 are opened on the cover body 1. A baffle 12 is provided on the connecting rod 11 to prevent rainwater from flowing out through the through groove between the connecting rod 11 and the cover body 1.

[0035] A filter 15 is provided at the bottom of the side of the mounting platform 3 to prevent impurities such as leaves and bird droppings from falling into the dust reduction cylinder, thereby improving the accuracy of detection. The mesh diameter of the filter 15 is 1-5 mm, and a cleaning brush 16 is provided on the upper surface of the filter 15. An execution unit 17 for driving the cleaning brush 16 to rotate is provided in the mounting platform 3. By driving the cleaning brush 16 to rotate by the execution unit 17, the rainwater remaining on the filter 15 can be cleaned into the dust reduction cylinder, thereby improving the accuracy of the detection of impurity content in the atmosphere. The staff can also control the execution unit 17 to drive the cleaning brush 16 according to environmental requirements. The cleaning brush 16 can clean leaves or larger particles that fall on the filter 15, thereby improving the accuracy of detection.

[0036] In the embodiment, the executing unit 17 comprises a motor, two bevel gears and a connecting shell, one of the bevel gears is connected with the output shaft of the motor, the other bevel gear is connected with the connecting shell, the connecting shell is rotationally connected with the outer circumferential surface of the mounting table 3, the connecting shell drives the cleaning brush 16 to start rotating by controlling the motor to work under the transmission of the two bevel gears, so as to clean the residual moisture on the filter screen 15.

[0037] Further, the mounting table 3 is also provided with a power supply and a controller, wherein the power supply is used to supply power to the controller and the executing unit 17, and the controller is used to control the executing unit 17 to work. The mounting table 3 has a cavity for mounting the executing unit 17 and the power supply. A sensor 25 can be arranged on the mounting table 3 or the cover body 1. The sensor 25 can be one of a liquid level sensor, a light sensor and an ultrasonic sensor. The liquid level sensor is arranged on the mounting table 3 and is used to detect the water level in the dust falling cylinder. The light sensor and the ultrasonic sensor can be arranged on the cover body 1. The light sensor can determine the rain condition by measuring the absorption and reflection of light by rain. The ultrasonic sensor can determine the rain condition by emitting ultrasonic waves and receiving reflected ultrasonic waves to measure the distance between the surrounding objects and the sensor. In actual use, the sensor can send a signal to the controller after the rain stops, and the controller controls the executing unit 17 to work to rotate the cleaning brush 16 to clean the rainwater remaining on the filter screen 15 into the dust falling cylinder.

[0038] As shown in Figure 6 The connecting piece comprises a support 4 and a reinforcing rib 5 arranged at the end of the support 4. The support 4 and the reinforcing rib 5 are rotationally connected through an axis. The reinforcing rib 5 is used to avoid the deformation of the cover body 2 in the state of no force.

[0039] As shown in Figure 1 The lower part of the mounting table 3 is provided with a glycol solution releasing device. The releasing device is provided with a plurality of liquid storage barrels 18 from bottom to top. The mounting table 3 and the plurality of liquid storage barrels 18 are connected through buckles 19 two by two. The side walls of the liquid storage barrels 18 are provided with mounting plates 20. The upper part of the mounting plate 20 is provided with liquid outlet holes 21 which are connected with the interiors of the liquid storage barrels 18. When it is a rainy day, when the rainwater falls into the dust falling cylinder and reaches a certain height, it enters the liquid storage barrels 18 through the liquid outlet holes 21. Due to the continuous movement of molecules, the glycol in the liquid storage barrels 18 enters the dust falling cylinder, so as to ensure the concentration of glycol in the dust falling cylinder, avoid freezing and inhibit the growth of microorganisms and algae, ensure the accuracy of test sample collection and test data, and save cost.

[0040] The above-mentioned snap fastener 19 can be an ordinary nut, a spring snap fastener or an M snap fastener / W snap fastener, etc. In this embodiment, the snap fastener includes a snap-fit ​​seat and a snap-fit ​​strip. The snap-fit ​​seat is arranged at the bottom of the mounting platform 3 and the two liquid storage barrels 18 located above, and the snap-fit ​​strip is arranged at the bottom of the sides of the three liquid storage barrels 18. When connecting, the snap-fit ​​strip is inserted into the snap-fit ​​seat by rotating the liquid storage barrel 18. In order to facilitate the connection between the snap-fit ​​seat and the snap-fit ​​strip, an annular stop is provided on the top of the inner wall of the liquid storage barrel 18, and a groove corresponding to the stop is provided at the bottom of the mounting platform 3 and the two liquid storage barrels 18 located above.

[0041] Furthermore, by changing the opening size of the cover body 2 as needed, the mounting platform 3 is moved up and down, thereby causing the release device to move up and down accordingly. For example, in the north, a dust suppression cylinder with an opening size of 15CM is required. At this time, in this device, by controlling the mounting platform 3 to move up, the opening size of the cover body 2 is used as the opening of the dust suppression cylinder. Since there is less rain in the north, the speed at which the rainwater level in the dust suppression cylinder rises is slow, and the speed at which ethylene glycol is diluted is also slow. The liquid in the dust suppression cylinder is usually collected directly after the rain. Therefore, by making the release device Moving it upward can avoid the waste of ethylene glycol; in the south, a dust suppression cylinder with an opening size of 40CM is needed. By controlling the mounting platform 3 to move downward, the opening size of the cover 1 is used as the opening of the dust suppression cylinder. Since there is a lot of rain in the south and it lasts for a long time, the rainwater level in the dust suppression cylinder rises faster and the ethylene glycol is diluted faster. By moving the release device downward, the ethylene glycol can be released in advance, thereby maintaining the concentration of ethylene glycol in the dust suppression cylinder, avoiding freezing and the growth of microorganisms and algae due to low ethylene glycol concentration.

[0042] In one embodiment, a remote signal receiver is provided in the mounting platform 3, and the staff can use the remote terminal to send a signal to the remote signal receiver according to the weather. After the remote signal receiver receives the signal, the controller controls the execution unit 17 to rotate the cleaning brush 16.

[0043] In order to prevent birds or bird droppings (part) from falling on the filter screen 15, a bird-proofing member 23 is provided on the top of the cover body 1. The bird-proofing member 23 includes a base and a bird-proofing needle. The bottom end of the bird-proofing needle is plugged into or threadedly connected to the base.

[0044] The automatic adjustment device for the atmospheric dust suppression cylinder proposed in this embodiment is used, for example, Figure 9As shown, the staff buckles the device on the dust suppression cylinder, and then adjusts the height of the mounting platform 3 according to the region. For example, when conducting atmospheric deposition monitoring in the southern region, a dust suppression cylinder with an opening radius of 40CM is required. By buckling the cover body 1 on the dust suppression cylinder, and then pulling the connecting ring 13 down, until the connecting rod 11 fits with the bottom of the inner wall of the through groove, during this process, the mounting platform 3 and the release device move down synchronously, and the locking bolt 14 is used to limit the connecting ring 13. At this time, the retaining ring 9 fits with the bottom of the inner wall of the annular groove 6 to prevent rainwater from flowing out through the drainage hole 7. The rainwater falls into the cover body 1, and part of it directly The water falls through the inner ring on the cover body 2 onto the guide cover 22, and the other part slides down onto the guide cover 22 under the inclined guide of the cover body 2, and then enters the dust reduction cylinder through the filtration of the filter 15. As the water level in the dust reduction cylinder continues to rise, when the water enters the liquid storage barrel 18 through the liquid outlet 2, the ethylene glycol in the liquid storage barrel 18 flows into the dust reduction cylinder, ensuring the concentration of ethylene glycol in the dust reduction cylinder, which can inhibit the growth of bacteria. When the rain stops, the sensor receives the rain stop signal, and the controller controls the execution unit 17 to start working and drive the cleaning brush 16 to rotate one circle. The cleaning brush 16 brushes the rainwater remaining on the filter 15 into the dust reduction cylinder.

[0045] Example 2

[0046] Compared with the first embodiment, the second embodiment is different in that Figure 7 -8 shows:

[0047] Each mounting plate 20 is provided with a slide rail, and multiple mounting plates 20 are slidably connected to a lifting plate 24 via the slide rail. A liquid outlet trough 25 corresponding to the liquid outlet hole 21 is provided at the bottom of the lifting plate 24, and the bottom of the liquid outlet trough 25 is an open structure. A buoyancy ball 26 is connected to one side of the lifting plate 24 via a rope. In this embodiment, the liquid outlet hole 21 is provided at the bottom of the side wall of the liquid storage barrel 18. During use, as the water level in the dust suppression tank continues to rise, the buoyancy ball 26 drives the lifting plate 24 upward. When the liquid outlet trough 25 is connected to the liquid outlet hole 21, the ethylene glycol solution in the liquid storage barrel 18 flows into the dust suppression tank, thereby increasing the concentration of the ethylene glycol solution in the dust suppression tank. By adopting this solution, it is possible to prevent external water vapor from entering the liquid storage barrel 18 through the liquid outlet hole 21, thereby reducing the volatilization rate of the ethylene glycol solution.

[0048] The embodiments of the present invention are described above in conjunction with the accompanying drawings, but the present invention is not limited to the above-mentioned specific implementation methods. The above-mentioned specific implementation methods are merely illustrative and not restrictive. Under the guidance of the present invention, ordinary technicians in this field can also make many forms without departing from the scope of protection of the present invention and the claims, all of which fall within the scope of protection of the present invention.
