[0020] The present invention is further described below through specific embodiments in conjunction with the accompanying drawings, but the present invention is not limited thereto. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principle of the present invention should be included in the protection scope of the present invention.

[0021] Example

[0022] A rainwater inspection well described in this embodiment, such as Figure 1 and Figure 3 As shown, it includes a rainwater well body. The rainwater well is an existing known product, which is mainly composed of a well shaft 2, a drainage pipe 3 and a well cover 11; the well cover 11 is located at the top of the well shaft 2. When the drainage pipes 3 are installed, there are two left and right ones. The left and right side walls of the well shaft 2 are both provided with mounting holes that communicate with each other inside and outside, and the two drainage pipes 3 are respectively installed in the mounting holes; when the drainage pipes 3 are installed, the drainage pipes 3 are connected to the inside of the well shaft 2; the top of the well cover 11 has a plurality of water inlet holes that communicate with each other up and down; when in use, the rainwater well The main body is installed underground, and the rear drainage pipe 3 is connected to the pipe of the downstream drainage system (such as the urban drainage network, river, etc.); when it rains, rainwater can flow into the wellbore 2 from the water inlet hole on the manhole cover 11, and be discharged into the pipe of the drainage system through the drainage pipe 3; when the manhole cover 11 is produced, it can be made of iron or composite materials, so that it can withstand the heavy pressure of pedestrians, vehicles, etc.; when the manhole cover 11 is produced, it can be built of concrete, bricks or other durable materials, and its inner wall may be treated with rust and corrosion prevention to enhance durability;

[0023] like Figure 1 and Figure 2 As shown, a basket 1 is arranged in the shaft 2 on the rainwater well body. The cross sections of the shaft 2 and the basket 1 in the present design are both circular structures. When in use, the opening of the basket 1 is upward and is located directly below the well cover 11. A number of drainage holes are provided on the side wall and the bottom of the basket 1. When it rains, if the rainwater flowing down from the well cover 11 contains impurities, such as leaves, garbage, mud and sand, etc., they can fall into the basket 1, and the basket 1 can filter the rainwater to prevent the problem of clogging the shaft 2 and the drainage pipe 3. When the basket 1 is produced, it can be made of PE (polyethylene) or stainless steel. PE (polyethylene) is an environmentally friendly plastic material, which is non-toxic and pollution-free, and has good corrosion resistance and weather resistance. Stainless steel has excellent corrosion resistance and mechanical strength, and can effectively block garbage and impurities in the initial rainwater, ensuring that the rainwater entering the reservoir is relatively clean. At the same time, the stainless steel material is also easy to clean and maintain, extending the service life.

[0024] like Figure 1 and Figure 2As shown, the basket 1 is limited on the shaft 2 by the limiting ring 12; when the limiting ring 12 is specifically installed, the limiting ring 12 is sleeved around the outer side of the top of the basket 1; an annular groove for the limiting ring 12 to be embedded is provided on the top of the shaft 2, and when the limiting ring 12 is placed in the annular groove, the purpose of limiting the limiting ring 12 can be achieved, because the limiting ring 12 is fixed on the basket 1, so the basket 1 can be limited in the shaft 2; when in use, the basket 1 is placed in the shaft 2, and during the placement process, the limiting ring 12 can be stuck in the annular groove, thereby achieving the purpose of installing the basket 1; the limiting ring 12 can also be made of PE (polyethylene) or stainless steel during production;

[0025] It is further preferred that a handle is installed on the top of the limiting ring 12. When in use, the limiting ring 12 can be easily removed from the annular groove by operating the handle, thereby facilitating the removal of the basket 1 from the wellbore 2.

[0026] like Figure 1 As shown, a scraper 10 for scraping off residues on the inner wall of the basket 1 is horizontally arranged in the basket 1. The structure of the scraper 10 is arranged according to the basket 1. Since the cross-sections of the shaft 2 and the basket 1 in the present design are both circular structures, the cross-section of the scraper 10 is also circular. The outer wall of the scraper 10 contacts the inner wall of the basket 1. Therefore, when the scraper 10 moves up and down in the basket 1, the impurities adhering to the inner wall of the basket 1 can be scraped off. The scraper 10 can be made of stainless steel, rubber or aluminum alloy during production.

[0027] like Figure 1 and Figure 2 As shown, a pull rod 6 is arranged in the basket 1, and the pull rod 6 is arranged vertically, and the lower end of the pull rod 6 is fixed to the top of the scraper 10; this section of the scheme as a whole constitutes a pulling assembly for pulling the scraper 10 to move up and down along the inner wall of the basket 1; the pull rod 6 is preferably fixed at the edge of the top of the scraper 10; when in use, by pulling the upper end of the pull rod 6 to move upward, because the pull rod 6 is connected to the scraper 10, the scraper 10 can be driven to move upward along the inner wall of the basket 1, and when the scraper 10 moves upward, the impurities remaining on the inner wall of the basket 1 can be scraped off, and finally the impurities can be taken out of the basket 1; the pull rod 6 can be made of stainless steel or aluminum alloy during production;

[0028] In a specific implementation process, the pull rod 6 in the pulling assembly can also be replaced by a pull rope, one end of which is fixed to the top of the scraper 10. When in use, by pulling the other end of the pull rope upward, the scraper 10 can be pulled upward to scrape away impurities on the inner wall of the basket 1.

[0029] like Figure 1As shown, there are two pull rods 6, which are symmetrically installed on the top of the scraper 10. Through the design of the two pull rods 6, the pull rods 6 can be pulled upward with both hands, so that the scraper 10 can be pulled upward more easily, and the scraper 10 can also scrape impurities on the inner wall of the basket 1 more stably;

[0030] like Figure 1 As shown, the top of the pull rod 6 is fixed with a limit plate 5, which can increase the contact area of ​​the hand, so that it is easier to pull the pull rod 6 to move upward; at the same time, the limit plate 5 can also be used in other ways to pull the pull rod 6 and the scraper 10 to move, such as first taking the basket 1 out of the shaft 2, and then turning the basket 1 upside down on the ground, then stepping on the two limit plates 5 with both feet, and holding the basket 1 with hands to move it upward, at this time, during the upward movement of the basket 1, the scraper 10 can scrape off the impurities remaining on the inner wall of the basket 1;

[0031] like Figure 1 As shown, a scraper strip 7 is provided on the scraper 10, and a through hole communicating with each other from top to bottom is opened on the scraper 10, and a rotating rod 8 is independently installed in the through hole, and the upper end of the rotating rod 8 is fixed to the bottom of the scraper strip 7; this section of the scheme as a whole constitutes a cleaning component for scraping off debris on the top of the scraper 10; the bottom of the scraper strip 7 contacts the top of the scraper 10; the through hole is located at the center of the scraper 10; because when rainwater flows into the basket 1 from the water inlet hole of the manhole cover 11, impurities in the rainwater will contact the inner wall of the basket 1 and the top of the scraper 10, so impurities will remain on the top of the scraper 10; at this time Because the rotating rod 8 is connected to the scraper bar 7, when the rotating rod 8 rotates, the scraper bar 7 can be driven to rotate along the center of the scraper 10. During the rotation process, the scraper bar 7 can scrape off the impurities on the top of the scraper 10, thereby achieving the purpose of cleaning the impurities on the top of the scraper 10; preferably, both ends of the scraper bar 7 extend to the edge of the top of the scraper 10; therefore, during the rotation of the scraper bar 7 along the center of the scraper 10, the impurities on the scraper 10 can be scraped off as comprehensively as possible; during the production, the scraper bar 7 can be made of stainless steel, rubber or aluminum alloy;

[0032] In a specific implementation process, the scraper bar 7 in the cleaning assembly can also be replaced by a brush, the brush head of the brush is in contact with the top of the scraper 10, and the impurities on the top of the scraper 10 can also be cleaned by the brush rotating along the top of the scraper 10;

[0033] like Figure 1The outer wall of the rotating rod 8 is provided with an external thread which is threadably matched with the threaded blind hole, so that the rotating handle 9 is convenient to remove and install from the rotating rod 8; when the rotating handle 9 is installed, it is convenient to operate the rotating handle 9 to drive the rotating rod 8 and the scraper 7 to rotate, thereby reducing the burden on the operator; when the rotating handle 9 is installed, the rotating handle 9 just fits the bottom of the scraper 10, and the bottom of the scraper 7 just fits the top of the scraper 10; therefore, the rotating rod 8 has no space to move up and down, so that in the process of the rotating handle 9 driving the rotating rod 8 to rotate, the scraper 7 can be more stably in contact with the top of the scraper 10, thereby avoiding the problem of the scraper 7 detaching from the scraper 10 during the rotation of the rotating rod 8; the purpose of being able to stably scrape impurities on the top of the scraper 10 is achieved;

[0034] like Figure 1 As shown, a limit block 4 for supporting the rotating rod 8 and the rotating handle 9 upward is arranged between the scraper 10 and the bottom of the basket 1. The limit blocks 4 are two left and right blocks. The limit blocks 4 are symmetrically arranged in the basket 1. The bottom of the limit blocks 4 is fixed to the bottom of the basket 1. When in use, the bottom of the scraper 10 contacts the top of the limit block 4, so the limit block 4 can support the scraper 10 upward. The height of the limit block 4 is greater than the height of the rotating handle 9, so that the rotating rod 8 and the rotating handle 9 are supported upward, thereby avoiding the rotating handle 9 from bearing the weight of the scraper 10, and achieving the purpose of protecting the rotating handle 9;

[0035] like Figure 1 As shown, the scraper 10 is provided with a plurality of water outlet holes which are connected with each other from top to bottom. When in use, the water outlet holes on the scraper 10 can filter the impurities on the top of the scraper 10, so that the rainwater can flow out quickly from the bottom of the basket 1, thereby improving the water filtering efficiency;

[0036] In the specific use process: first, the rainwater well body is installed underground, and then when it rains, rainwater flows into the basket 1 from the water inlet hole on the well cover 11, and the basket 1 can filter the garbage and debris in the rainwater; after the basket 1 has been used for a period of time, the garbage and debris in the basket 1 can be cleaned regularly, and at this time, the limiting ring 12 is taken out from the well shaft 2, thereby driving the basket 1 to be taken out from the well shaft 2, and the garbage and debris in the basket 1 are dumped out. After the dumping is completed, if there is garbage and debris stuck to the inner side of the basket 1, the limiting plate 5 is pulled to drive the pull rod 6 to move, and the pull rod 6 drives the scraper 10 to move in the basket 1. The scraper 10 can scrape off the garbage and debris on the inner wall of the basket 1 during the movement, so as to facilitate the cleaning of the garbage and debris remaining in the basket 1; after the scraper 10 is moved out of the basket 1, the handle 9 is operated to drive the rotating rod 8 to rotate, so as to drive the scraper bar 7 to rotate on the top of the scraper 10, so as to achieve the purpose of cleaning the top of the scraper 10; therefore, in this use process, it is convenient to clean the debris on the inner wall of the basket 1, avoiding the problem of time-consuming and labor-intensive cleaning of the debris inside the basket 1 in the prior art.
