[0002] A stormwater inlet is a structure that collects rainwater on a stormwater pipe or combined pipe. Rainwater on the street surface first flows through the stormwater inlet and then into the drainage pipe through a connecting pipe. The location of the stormwater inlet should ensure that ground rainwater is collected quickly and effectively. Generally, it should be set at intersections, at a certain distance from roadside ditches, and in low-lying places with road curbs to prevent rainwater from overflowing the road or causing water accumulation on the road and low-lying areas and hindering traffic. The form and number of stormwater inlets should usually be determined according to the runoff generated by the catchment area and the drainage capacity of the stormwater inlet.

[0003] There are two main types of rainwater outlets: vertical grate type and flat grate type, which are mainly composed of rainwater grates and rainwater wells. Once there is a heavy rain, the rainwater well is easily blocked by debris such as branches, affecting the water collection capacity. When manually clearing, you need to use tools to pry open the rainwater grate above, and then use corresponding tools to clear the debris in the rainwater well, which is time-consuming and laborious, and requires relatively high labor costs.

DETAILED DESCRIPTION

[0019] The present invention is further described below in conjunction with the accompanying drawings and embodiments. Unless otherwise defined, the technical terms or scientific terms used in the present invention should be the common meanings understood by people with ordinary skills in the field to which the present invention belongs. The above-mentioned features or features mentioned in the specific examples mentioned in the present invention can be combined arbitrarily, and these specific embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0020] Example 1 like Figure 1-2As shown, a rainwater well lined with a basket-type grille comprises a rainwater well 1 and a basket-type grille 2 therein. A movable locking rod 4 is provided in the locking groove 3 at the top of the rainwater well 1, and the movable locking rod 4 is threadedly connected with a locking sleeve 5 in the locking hole 21 at the top of the basket-type grille 2. An anti-falling net 22 is provided at the top of the basket-type grille 2, and a filter screen plate 23 is provided below the anti-falling net 22 of the basket-type grille 2, and an intercepting net box 24 is provided at the end of the filter screen plate 23. A water passage chamber 27 is formed between the side wall of the intercepting net box 24, the bottom of the filter screen plate 23 and the bottom of the basket-type grille 2, and the bottom of the water passage chamber 27 is connected to the main well of the rainwater well 1, and the side wall of the water passage chamber 27 is connected to the branch pipe port 11 of the rainwater well 1.

[0021] The rainwater well 1 is used to collect rainwater, and the basket-type grille 2 intercepts and collects garbage in the rainwater. When cleaning the garbage, the basket-type grille 2 can be directly taken out. The anti-fall net 22 is hung on the top of the basket-type grille 2 to prevent the user from accidentally falling when taking out or putting in the basket-type grille 2, thereby protecting the user. The garbage entering the basket-type grille 2 with the rainwater is intercepted by the filter screen plate 23, the interception net box 24, the interception screen plate 1 25 and the interception screen plate 2 26 in sequence, and the rainwater intercepted and filtered by the basket-type grille 2 enters the main well or the branch pipe port 11.

[0022] The locking groove 3 is divided into a positioning portion 31, a moving portion 32 and a locking portion 33 in sequence. The bottom height of the positioning portion 31 is lower than the top height of the moving portion 32, and the bottom height of the moving portion 32 is higher than the top height of the locking portion 33. The top opening of the locking portion 33 matches the shape of the locking block 43 at the bottom of the moving locking rod 4, and the interior of the locking portion 33 is a circular groove.

[0023] like Figure 6 As shown, the movable locking rod 4 is in different states in the positioning part 31, the moving part 32 and the locking part 33. When inside the positioning part 31, the upper middle part of the movable locking rod 4 is located outside the locking groove 3, which is convenient for quick connection with the locking hole 21 of the basket-type grille 2. The height between the positioning part 31 and the moving part 32 is set so that the movable locking rod 4 will not enter the moving part 32 when it is located in the positioning part 31. The side wall of the positioning part 31 is provided with a magnet, and the lower part of the movable locking rod 4 is made of iron material, which ensures that the movable locking rod 4 remains in a vertical state in the positioning part 31, which is convenient for connection with the locking hole 21.

[0024] When the movable locking rod 4 is connected to the locking hole 21 and then threadedly connected to the locking sleeve 5, the locking sleeve 5 drives the movable locking rod 4 from the positioning portion 31 to the movable portion 32 while the basket-type grille 2 is rotated. Since the movable portion 32 gradually decreases in height from the positioning portion 31 to the locking portion 33, the movable locking rod 4 and the locking sleeve 5 gradually move downward relative to the height of the basket-type grille 2.

[0025] like Figure 7As shown, when the movable locking rod 4 reaches the top of the locking portion 33, it falls into the locking portion 33 through the opening of the locking portion 33. At this time, the bottom of the movable locking rod 4 contacts the bottom of the locking portion 33, and the bottom of the top of the locking sleeve 5 contacts the top of the manhole cover 6. The locking sleeve 5 continues to rotate in the direction of tightening the thread through the I-shaped protrusion on the top of the locking sleeve 5, thereby driving the movable locking rod 4 to rotate inside the locking groove 3, driving the locking block 43 to not correspond to the position of the opening of the locking portion 33, thereby locking the basket-type grille 2 in the rainwater well 1.

[0026] The upper part of the movable locking rod 4 is provided with an external thread 41, and the mounting frame 42 at the lower part of the movable locking rod 4 is connected to the locking block 43. A rolling sleeve 44 is hinged at the center of the locking block 43, and the rolling sleeve 44 is slidably connected to the bottom of the locking groove 3. The movable locking rod 4 is threadedly connected to the internal thread of the locking sleeve 5 through the external thread 41, thereby connecting the movable locking rod 4 to the locking sleeve 5. With the arrangement of the rolling sleeve 44, when the movable locking rod 4 moves, the rolling sleeve 44 rotates relative to the locking block 43, so that the movable locking rod 4 quickly moves to a position in the locking groove 3.

[0027] like Figure 3 As shown, the filter screen plate 23 connected to the side wall of the basket-type grille 2 is arranged obliquely, and the vertical projection of the filter screen plate 23 and the vertical projection of the interception net box 24 together form a circle, and the interception net box 24 is provided with an interception filter 241 on the side in contact with the filter screen plate 23. The filter screen plate 23 is arranged obliquely, and the garbage impurities intercepted by the filter screen plate 23 can slide into the interception net box 24, and the interception filter 241 in the interception net box 24 intercepts the garbage and filters out the rainwater. A handle 242 is provided on the top of the interception net box 24, which is convenient for quickly putting the interception net box 24 into or taking it out of the basket-type grille 2.

[0028] like Figure 5 As shown, the locking sleeve 5 has a T-shaped cross-section, and the middle of the locking sleeve 5 is provided with an internal thread threadedly connected to the movable locking rod 4, and the locking sleeve 5 matches the size of the locking hole 21. The diameter of the top of the locking sleeve 5 is larger than the diameter of the locking hole 21, so that the movable locking rod 4 can be rotated by the protrusion on the top of the locking sleeve 5.

[0029] An interception mesh plate 25 is provided at the bottom of the water passage chamber 27 , and the water passage chamber 27 is connected to the main well through the interception mesh plate 25 , and the interception mesh plate 25 is in contact with the bottom of the interception filter 241 .

[0030] The side wall of the water passage chamber 27 is symmetrically provided with interception mesh plates 26, and the two interception mesh plates 26 correspond to the positions of the two branch pipe openings 11. Most of the rainwater in the water passage chamber 27 comes from the rainwater filtered by the filter mesh plate 23, and a small part comes from the rainwater filtered in the interception mesh box 24. After entering the water passage chamber 27, the rainwater is finally filtered and intercepted by the interception mesh plates 1 25 and 26.

[0031] like Figure 4 As shown, the manhole cover 6 of the rainwater well 1 is provided with a first rainwater hole 61 and a second rainwater hole 62, the first rainwater hole 61 is located above the interception net box 24, the second rainwater hole 62 is located above the filter screen 23, and the aperture of the second rainwater hole 62 is larger than the aperture of the first rainwater hole 61. The arrangement of the first rainwater hole 61 and the second rainwater hole 62 on the manhole cover 6 allows large particles of impurities to fall onto the filter screen 23 through the second rainwater hole 62, and the first rainwater hole 61 limits the particle size of impurities that can pass through, thereby preventing more impurities from entering the rainwater well 1 with the rainwater.

[0032] Example 2 The method for using the above-mentioned lined basket-type grille rainwater well comprises the following steps: S1. Open the manhole cover 6 of the rainwater well 1, put the interception net box 24 into the basket-type grille 2, and then adjust the movable locking rod 4 to the positioning part 31 of the locking groove 3.

[0033] S2. Place the basket-type grille 2 into the rainwater well 1. During the placement process, the locking hole 21 is correspondingly connected to the movable locking rod 4. After the connection, the locking sleeve 5 is passed through the locking hole 21 and threadedly connected to the movable locking rod 4.

[0034] S3, after tightening the locking sleeve 5, the basket-type grille 2 is rotated, and at the same time, the movable locking rod 4 is driven to move from the positioning part 31 to the movable part 32 and the locking part 33 in sequence, and finally enters the interior of the locking part 33.

[0035] After the locking block 43 , the rolling sleeve 44 and the mounting frame 42 of the movable locking rod 4 enter the locking portion 33 , the interception mesh plate 1 25 and the interception mesh plate 2 26 of the water passage chamber 27 are connected to the main well and the branch pipe opening 11 of the rainwater well 1 correspondingly.

[0036] S4, after the locking rod 4 is moved into the locking portion 33, the locking sleeve 5 is rotated to fix the basket-type grille 2 to the rainwater well 1, and then the well cover 6 is closed.

[0037] S5, when it is necessary to clean the basket-type grille 2, reverse the operations S1-S4 to clean the garbage and impurities in the basket-type grille 2.

[0038] Therefore, the present invention adopts a rainwater well lined with a basket-type grille of the above structure and a method of using the same, and uses the basket-type grille to separate rainwater and garbage impurities. The basket-type grille can be directly taken out to clean the garbage impurities inside it, saving cleaning time.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that they can still modify or replace the technical solution of the present invention with equivalents, and these modifications or equivalent replacements cannot cause the modified technical solution to deviate from the spirit and scope of the technical solution of the present invention.
