Description

Technical Field

[0001] The invention relates to the technical field of acid rain monitoring, in particular to an acid rain monitoring sampling device. Background Art

[0002] Acid rain is a term widely mentioned in both the scientific community and the public. Its official name is acid deposition, which refers to natural precipitation with a pH value below 5.6, as well as acidic gases and particulate matter that settle with precipitation. The formation of this phenomenon is the result of the interweaving of multiple complex environmental factors, among which the increasing atmospheric pollution plays a core role. With the acceleration of industrialization and the surge in energy consumption, a large amount of acidic gases such as sulfur dioxide and nitrogen oxides are emitted into the atmosphere. These gases combine with water vapor under suitable conditions and form acidic precipitation through chemical reactions, which we call acid rain.

[0003] The destructive power of acid rain on the earth's ecological environment cannot be underestimated. It not only erodes forest vegetation, causes soil acidification, and affects crop growth, but also seriously destroys the balance of aquatic ecosystems and reduces biodiversity. More seriously, acid rain accumulates through the food chain and ultimately poses a potential threat to human health, such as increasing the risk of respiratory diseases and affecting water quality safety. Therefore, the environmental acidification problem caused by acid rain has far exceeded the ability of nature to recover, and has become an environmental challenge that needs to be urgently addressed worldwide, which has aroused the deep concern and extensive discussion of human society.

[0004] Among the many measures to deal with the acid rain problem, accurately and efficiently monitoring acid rain conditions and collecting and analyzing its sample data are the prerequisites for formulating scientific governance strategies. However, traditional acid rain monitoring and sampling equipment has many design deficiencies, especially in the management of the connection status between the collection tube and the cylinder.

[0005] Existing technologies often require manual operation to open or close the connection state, which not only increases the complexity of operation and reduces work efficiency, but also brings inconvenience to filtering debris in rainwater in practical applications. Whenever the filtration system needs to be cleaned, the user has to interrupt the monitoring process and perform tedious maintenance work, which undoubtedly affects the continuity and integrity of the data;

[0006] In addition, traditional equipment also has obvious defects in the classification and collection of rainwater and debris. Due to design limitations, it is difficult to effectively separate rainwater and solid impurities contained therein, which poses an obstacle to subsequent scientific analysis. Summary of the invention

[0007] The purpose of the present invention is to provide an acid rain monitoring sampling device, which can adjust the connection state between the collecting tube and the inside of the cylinder by inserting or pulling out the collecting tube, eliminating the cumbersome steps of manual switch, thereby improving the overall operation efficiency.

[0019] Furthermore, the feed pipe is a hollow cylindrical structure, the inner diameter of the feed pipe is greater than or equal to the outer diameter of the bottom of the collecting tube, the limit rod is a T-shaped structure, and the protruding part at the bottom of the limit rod is used to limit the downward movement of the bottom plate and the separation of the limit rod.

[0020] Furthermore, the top of the spring is connected to the inner top of the cylinder, the bottom of the spring is connected to the top of the bottom plate, a sealing gasket is provided on the top of the bottom plate, the top of the support rod moves to contact the bottom of the collection tube, and the support rod is provided in multiple groups.

[0021] Furthermore, the size of the opening at the top of the temporary storage seat is larger than the size of the bottom plate, the interior of the temporary storage seat is funnel-shaped, and the free end of the bracket is fixedly connected to the inner wall of the cylinder.

[0022] Furthermore, the size of the filter is greater than or equal to the bottom size of the discharge pipe, the fixing frame is a plate-like structure, the mounting seat is a T-shaped structure, the mounting seat is fixedly connected to the inner wall of the cylinder, and the extended end of the telescopic rod is hinged to the bottom of the fixing frame.

[0023] Furthermore, the rollers are provided with a plurality of groups distributed in a straight line in the cylinder, the sum of the lengths of the collecting seat and the water storage seat is greater than the sum of the diameters of the cylinder and the discharge pipe, and the water storage seat is below the discharge pipe.

[0024] Compared with the prior art, the technical advantages of the present invention are significant, which not only greatly improves the work efficiency, but also realizes the convenience of rainwater collection and treatment, which is specifically reflected in the following aspects:

[0025] 1. Flexible and convenient connection and regulation mechanism: A highlight of the present invention is its innovative connection mechanism between the collection tube and the cylinder. The user only needs to simply move the cylinder to the preset rainwater collection position, and then accurately insert the bottom of the collection tube into the feed tube. In this process, the collection tube will cleverly contact the built-in support rod, and through the precise force of the support rod, push the bottom plate to slowly move down. While the bottom plate moves down, it will stretch the spring. This design not only ensures the smoothness of the movement, but also stores the recovery potential energy. When the bottom plate contacts the carefully designed protrusion at the bottom of the limit rod, its downward movement is precisely limited, thereby perfectly realizing the connection between the collection tube and the inside of the cylinder. It is worth noting that when it is necessary to end the rainwater collection, the user only needs to easily pull out the collection tube. At this time, the collection tube and the support rod are naturally separated, and the spring immediately uses its stored energy to restore its original state, pull the bottom plate up and fit tightly to the bottom of the feed tube, instantly cutting off the connection between the feed tube and the inside of the cylinder, and effectively preventing further entry of rainwater. This simple operation of plugging and unplugging completely eliminates the tedious steps of traditional manual opening and closing. It not only greatly improves work efficiency, but also realizes the automation of operations. It is a significant advancement in rainwater collection technology.

[0026] 2. Efficient and intelligent rainwater filtration mechanism: After the rainwater enters the present invention, it first passes through the collection pipe directly to the bottom of the feed pipe, is then guided to the temporary storage seat, and finally flows into the discharge pipe. In this path, the innovative filter design plays a key role. When the rainwater flows through the filter, the impurities are effectively filtered and stay above the filter, ensuring the purity of the collected rainwater. Furthermore, the present invention is equipped with a driving telescopic rod, which pulls the fixed frame to rotate elegantly on the mounting seat through its precise contraction action. This rotation drives the synchronous flipping of the filter, so that the filter finally presents a tilted state. In this tilted state, the accumulated debris slides off and is separated from the filter, which not only ensures the filtration efficiency, but also simplifies the cleaning process of the debris and enhances the rainwater filtration effect.

[0027] 3. Integrated rainwater and debris classification and collection solution: Rainwater filtered by the filter falls into the water storage seat pure and flawless, waiting for further use or treatment. Another major innovation of the present invention lies in its integrated rainwater and debris classification and collection design. Before the filter needs to be cleaned, the user only needs to simply push the limit plate to allow the collection seat to smoothly enter the cylinder body and accurately position it when it contacts the outer wall of the cylinder. At this time, the collection seat is just below the filter. When the filter is flipped to an inclined state by the drive of the telescopic rod, all the debris that slides down falls into the collection seat without omission, realizing the automatic classification and collection of rainwater and debris. This design not only facilitates subsequent processing work, but also provides strong support for the recycling of rainwater resources and environmental protection, and enhances the effect of rainwater collection and treatment.

[0028] To sum up, the technical advantages of the present invention are not only reflected in the intelligence and automation of various operations, but also in its significant improvement in the efficiency of rainwater collection, filtration and classification processing, contributing to the efficient utilization of rainwater resources and environmental protection.

[0040] 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.

[0041] See also Figure 1-6The present invention provides a technical solution: an acid rain monitoring sampling device, comprising a cylinder 1 and a collecting tube 2, a supporting leg 4 is provided at the bottom of the cylinder 1, a collecting device 3 is provided inside the cylinder 1, a filtering device 5 is provided on the cylinder 1 above the collecting device 3, and the filtering device 5 is used to filter rainwater;

[0042] The filtering device 5 comprises a capping mechanism 510 disposed on the top of the cylinder 1 , a temporary storage mechanism 520 is disposed below the capping mechanism 510 , and a filtering mechanism 530 is disposed below the temporary storage mechanism 520 .

[0043] The capping mechanism 510 is used to install the collecting tube 2 and connect the cylinder 1 and the collecting tube 2; the capping mechanism 510 includes a feed tube 511 fixedly passing through the top of the cylinder 1, a limit rod 512 is provided on the top of the cylinder 1 on one side of the bottom of the feed tube 511, the limit rod 512 moves through a bottom plate 514 for moving and blocking the bottom opening of the feed tube 511 and a spring 513 for pulling the bottom plate 514 to fit the bottom of the feed tube 511, a support rod 515 for moving and contacting the bottom of the collecting tube 2 is provided on the bottom plate 514, and the feed tube 511 is a hollow cylinder shaped structure, the inner diameter of the feed pipe 511 is greater than or equal to the outer diameter of the bottom of the collecting tube 2, the limiting rod 512 is a T-shaped structure, the protruding part at the bottom of the limiting rod 512 is used to limit the downward movement of the bottom plate 514 and the separation of the limiting rod 512, the limiting rod 512 and the top of the spring 513 are both connected to the inner top of the cylinder 1, the bottom of the spring 513 is connected to the top of the bottom plate 514, the gravity of the bottom plate 514 is less than the force of the deformation of the spring 513 is less than the gravity of the collecting tube 2, a sealing gasket is provided on the top of the bottom plate 514, the top of the support rod 515 moves to contact the bottom of the collecting tube 2, and the support rod 515 is provided in multiple groups.

[0044] After the cylinder 1 is moved to the predetermined rainwater collection position, the next step is particularly critical and smooth. The bottom of the collection tube 2 is slowly inserted into the interior of the feed tube 511. During this process, the collection tube 2 gradually goes deeper until it touches the carefully designed support rod 515. With its stable posture, the support rod 515 pushes the bottom plate 514 to start moving downward. The downward movement of the bottom plate 514 is not without resistance, but is accompanied by the gradual stretching of the spring 513. This design not only improves the smoothness of the action, but also adds structural elasticity and reliability.

[0045] When the bottom plate 514 continues to move downward until its bottom contacts the protruding portion at the bottom of the limiting rod 512, the limiting mechanism is activated, preventing the bottom plate 514 from moving downward further. At this moment, the collecting tube 2 is connected to the inside of the cylinder 1, and the rainwater collection channel is successfully opened. When the collection task is completed and the collecting tube 2 needs to be taken out, this connection process can be quickly interrupted. The separation of the collecting tube 2 from the support rod 515 releases the accumulated force of the spring 513, which quickly returns to its original state, pulling the bottom plate 514 upward until the bottom plate 514 fits tightly against the bottom of the feed tube 511, forming a tightly enclosed space, effectively cutting off the path for rainwater to enter the cylinder 1.

[0046] The present invention can adjust the connection state between the collecting tube 2 and the inside of the cylinder 1 by inserting and removing the collecting tube 2, thereby improving the convenience and efficiency of operation. Compared with the cumbersome steps of traditional manual opening and closing, the overall working effect of the present invention is effectively improved.

[0047] The temporary storage mechanism 520 is located directly below the feed pipe 511 and is composed of a temporary storage seat 521 and a bracket 522 on its periphery. The bracket 522 not only firmly supports the temporary storage seat 521, but also ensures the stability of the entire structure through the tight connection between its free end and the inner wall of the cylinder 1. The top opening size of the temporary storage seat 521 is larger than the bottom plate 514, so that rainwater can flow in smoothly, and its internal funnel-shaped structure is conducive to the concentration and guidance of rainwater. The feed pipe 523 at the bottom of the temporary storage seat 521 is the only channel for rainwater to flow to the bottom of the cylinder 1.

[0048] The filtering mechanism 530 exists to make the rainwater entering the cylinder 1 pure and free of impurities. The filter screen 531, a key component, is flipped and contacts the bottom of the discharge pipe 523. Its size design can cover the discharge port and effectively intercept debris in the rainwater. One end of the filter screen 531 is firmly fixed by the fixing frame 532, and the other end of the fixing frame 532 is cleverly hinged on the top of the mounting seat 533. The T-shaped structure of the mounting seat 533 is not only stable, but also provides an installation position for the telescopic rod 534 thereon. The telescopic rod 534, as a power source for pushing the fixing frame 532 to flip, has its protruding end hinged to the bottom of the fixing frame 532. Through the telescopic action, the filter screen can be opened and closed, thereby filtering impurities in the rainwater.

[0049] The rainwater is first guided to the bottom of the feed pipe 511 through the carefully designed collection pipe 2. This process allows the rainwater to be introduced in an orderly manner, avoiding the problem of impurities mixed in due to direct impact or disordered flow. The feed pipe 511 serves as a transition channel, which utilizes the effect of gravity to allow the rainwater to flow smoothly into the temporary storage seat 521. The temporary storage seat 521 serves as a temporary buffer zone, which not only provides a smooth transition environment for the rainwater, but also improves the continuity and stability of subsequent processing steps.

[0050] Then, the rainwater flows from the temporary storage seat 521 into the feed pipe 523. During this process, the flow rate of the rainwater is further regulated, which lays a good foundation for the subsequent filtering steps. The end of the feed pipe 523 is connected to the filter screen 531, which is a crucial filtering link in the entire device. The filter screen 531 is made of high-quality filtering material and can effectively intercept debris in the rainwater, such as leaves.

[0051] When the debris accumulates to a certain extent above the filter 531, the telescopic rod 534 is driven to begin to shrink. This action pulls the fixing frame 532 to slowly rotate on the mounting seat 533 through mechanical linkage. The rotation of the fixing frame 532 drives the filter 531 to flip, so that it gradually changes from a horizontal state to an inclined state. This tilting action not only allows the debris to naturally slide off and separate from the filter 531 due to gravity, but also simplifies the cleaning process and improves work efficiency.

[0052] At the same time, the design of the collection device 3 also fully considers the needs of classified collection of rainwater and debris. It includes a roller 31 that is rotatably arranged in the cylinder 1, and a collection seat 32 and a water storage seat 33 are slidably arranged on the roller 31. The collection seat 32 is used to collect debris that slides off the filter 531, while the water storage seat 33 is responsible for receiving clean rainwater after filtering. A baffle 34 is provided at one end of the water storage seat 33. This design not only limits the water storage seat 33 from entering the cylinder 1, but also provides a valve body 35 thereon, so that the user can easily take out the rainwater in the water storage seat 33.

[0053] A limit plate 36 is provided at one end of the collecting seat 32, and this design also serves to limit the range of motion of the collecting seat 32. The rollers 31 are distributed in a straight line in the cylinder 1, and multiple groups are provided, so that the collecting device 3 can operate efficiently. The sum of the lengths of the collecting seat 32 and the water storage seat 33 is greater than the sum of the diameters of the cylinder 1 and the discharge pipe 523. This design improves the full deployment and stable operation of the two in the cylinder 1. The water storage seat 32 is located below the discharge pipe 523, so that the filtered rainwater can fall directly into it.

[0054] In actual operation, the user only needs to push the limiting plate 36 to allow the collecting seat 32 to enter the cylinder 1, and then perform the step of retracting the telescopic rod 534. When the limiting plate 36 contacts the outer wall of the cylinder 1, the collecting seat 32 is just below the filter 531. At this time, the tilting action of the filter 531 causes the debris to slide smoothly into the collecting seat 32 for collection. This process not only realizes the effective classification and collection of rainwater and debris, but also provides convenience for subsequent processing.

[0055] The working principle of the acid rain monitoring sampling equipment of the present invention is:

[0056] The present invention moves the cylinder 1 to the place where rainwater needs to be collected, and then inserts the bottom of the collecting tube 2 into the feeding tube 511. After the collecting tube 2 enters the feeding tube 511, it contacts the support rod 515, and the support rod 515 pushes the bottom plate 514 to move downward. The bottom plate 514 moves downward to stretch the spring 513. When the bottom plate 514 contacts the protruding part at the bottom of the limit rod 512, it is restricted from moving downward. The collecting tube 2 is connected to the inside of the cylinder 1, and the collecting tube 2 is taken out to block the feeding tube 511. When the collecting tube 2 is taken out, the collecting tube 2 is separated from the support rod 515, and the spring 513 returns to its original state to pull the bottom plate 514 upward, and the bottom plate 514 moves upward to fit and contact the bottom of the feeding tube 511, restricting the feeding tube 511 from being connected to the inside of the cylinder 1, thereby restricting rainwater from entering the cylinder 1. The connecting state between the collecting tube 2 and the inside of the cylinder 1 can be adjusted by inserting and pulling out the collecting tube 2, avoiding the need for manual opening and closing, thereby improving the overall working effect. The bottom of the filter 531 is then fed into the temporary storage seat 521 through the feed pipe 511, and then into the discharge pipe 523, and filtered through the filter screen 531. The filtered debris stays above the filter screen 531, and the telescopic rod 534 is driven to shrink and pull the fixing frame 532 to rotate on the mounting seat 533. The fixing frame 532 rotates to make the filter screen 531 turn over, and the filter screen 531 turns over and becomes inclined, and the debris slides off and separates from the filter screen 531, making it easy to filter rainwater debris and at the same time easy to clean the filtered area. The filtered rainwater falls into the water storage seat 33 for collection, and the rainwater in the water storage seat 33 can be quickly taken out through the valve body 35. Before operating the above-mentioned step of retracting the telescopic rod 534, the limit plate 36 is pushed to make the collecting seat 32 enter the cylinder 1. When the limit plate 36 contacts the outer wall of the cylinder 1, the collecting seat 32 is below the filter screen 531. After the filter screen 531 is tilted, the debris slides into the collecting seat 32 for collection, making it easy to classify and collect rainwater and debris for subsequent processing.

[0057] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
