[0020] In order to further understand the utility model content, characteristics and effects of the utility model, the following examples are cited, and the drawings are described in detail as follows.

[0021] The structure of the utility model will be described in detail below with reference to the drawings.

[0022] As Figs. 1 to 4 shown, the utility model embodiment provides a pipe well search entrance plugging and dredging device, including the base plate 1 for being fixed in the pipe well search entrance, the base plate 1 is hollowly arranged, the cover plate is movably placed on the upper portion of the base plate 1, the cover plate includes the lower layer cover plate 4, the lower layer cover plate 4 is movably placed on the upper portion of the base plate 1, the upper layer cover plate 2 is rotatably installed on the upper portion of the lower layer cover plate 4, the second water inlet 5 is formed in the lower layer cover plate 4, the first water inlet 3 is formed in the upper layer cover plate 2, the upper layer cover plate 2 can be rotated on the lower layer cover plate 4 under the driving of external force, and the alignment or staggered action of the first water inlet 3 and the second water inlet 5 is formed, forming a variable water inlet.

[0023] The base plate 1 of the above device is used for being fixed in the pipe well search entrance, ensuring its stability.The hollow design of the base plate 1 enables rainwater to enter smoothly.The cover plate is composed of the lower layer cover plate 4 and the upper layer cover plate 2.The lower layer cover plate 4 is movably placed on the upper portion of the base plate 1, and the upper layer cover plate 2 is rotatably installed on the upper portion of the lower layer cover plate 4.

[0024] The second water inlet 5 and the first water inlet 3 of the lower layer cover plate 4 and the upper layer cover plate 2 are the same structure and overlap each other.When the upper layer cover plate 2 is rotated clockwise, the first water inlet 3 and the second water inlet 5 overlap, forming the largest water inlet, allowing more rainwater to flow into the pipe well.Conversely, when the upper layer cover plate 2 continues to rotate, the first water inlet 3 and the second water inlet 5 stagger, and the size of the water inlet is reduced, thereby reducing the inflow amount.When not in contact, the two water inlets are closed to each other, effectively preventing water flow from entering.

[0025] The user can adjust the relative position of the first water inlet 3 and the second water inlet 5 by rotating the upper layer cover plate 2 to control the size of the water inlet.This design enables the user to flexibly adjust the water inflow according to the rainwater condition.Through the overlapping and staggered water inlet design, the user can freely adjust the opening size of the water inlet according to the actual rainwater amount, thereby improving the drainage efficiency and avoiding the blockage caused by excessive rainwater.

[0026] In this embodiment, the first water inlet 3 is provided with three, and the three first water inlets 3 are circumferentially uniformly arranged on the upper portion of the upper layer cover plate 2.The second water inlet 5 is provided with three, and the three second water inlets 5 are circumferentially uniformly arranged on the upper portion of the lower layer cover plate 4.

[0027] The upper cover plate 2 is provided with three first water inlets 3, which are evenly distributed on the circumference of the upper cover plate 2. Such a layout ensures that the flow is evenly distributed when rainwater or other liquids flow in, avoiding concentration in a certain point. The lower cover plate 4 is also provided with three second water inlets 5, which are evenly arranged on the upper part of the lower cover plate 4. This symmetrical design enhances the overall stability of the device and improves the water inlet efficiency.

[0028] When the user rotates the upper cover plate 2 by external force, the three first water inlets 3 can achieve different alignment or staggered states with the three second water inlets 5. It can flexibly respond to different rainwater conditions, effectively improve the drainage efficiency and reduce safety hazards.

[0029] In this embodiment, the lower part of the base plate 1 is also fixedly installed with a filter screen 7, which performs the action of screening debris from the sewage transmitted by the variable water inlet.

[0030] The filter screen 7 is fixedly installed on the lower part of the base plate 1, and its position is designed below the variable water inlet, ensuring that all sewage passing through the water inlet can flow into the filter screen 7. The filter screen 7 is usually made of corrosion-resistant materials and has a certain pore size to screen out debris as needed.

[0031] When rainwater or other liquids flow in through the variable water inlet, the water flow will first pass through the filter screen 7. At this time, the speed and direction of the water flow can be controlled to a certain extent by adjusting the rotation of the upper cover plate 2. The function of the filter screen 7 is to filter and screen debris in the water. Because the filter screen 7 has a reasonable pore size, it can effectively capture solid particles, leaves, soil and other impurities in the sewage, while allowing clean water to continue to flow into the pipeline system. Through debris screening, the filter screen 7 can reduce the pollution of sewage pollutants entering the pipeline, maintain the cleanliness of the pipeline, and reduce the maintenance and cleaning frequency of subsequent equipment.

[0032] In this embodiment, the plugging and dredging device also includes a linkage lifting assembly 6, which includes a gear ring 601, the middle part of which is fixedly connected with the upper cover plate 2 through the lower cover plate 4. A plurality of gears 602 are rotatably installed on the lower part of the lower cover plate 4, and the gears 602 are meshingly connected with the gear ring 601. Each gear 602 is fixedly connected with a lead screw 603 below, and the lead screw 603 is fixedly connected with a limiting plate 605 below. Each lead screw 603 is externally screwed with the same lifting ring 604, and the lifting ring 604 is fixed on the lower part of the filter screen 7. The bottom of the filter screen 7 is controlled to perform lifting action by the upper cover plate 2.

[0033] The linkage lifting assembly 6 is composed of a gear ring 601, a gear 602, a lead screw 603, a limiting plate 605 and a lifting ring 604. The middle part of the gear ring 601 penetrates through the lower cover plate 4 and is fixedly connected with the upper cover plate 2 to form an integrated structure. The lower part of the lower cover plate 4 is rotatably provided with a plurality of gears 602, which are engaged with the gear ring 601. When the upper cover plate 2 rotates, the gear ring 601 also rotates to drive the gears 602 connected therewith to rotate. The lower part of each gear 602 is fixedly connected with a lead screw 603, and the rotation of the lead screw 603 causes the lifting ring 604 to move up and down. The lead screw 603 is externally screwed with the lifting ring 604, and the lifting ring 604 is fixed to the lower part of the filter screen 7.

[0034] When the upper cover plate 2 rotates to the maximum water inlet state, the linkage lifting assembly 6 drives the lead screw 603 to rotate through the engagement of the gear ring 601 and the gear 602, and the lead screw 603 moves to extend the lifting ring 604 downward. The bottom of the filter screen 7 is controlled by the upper cover plate 2 and moves downward to increase the volume. With the downward movement of the filter screen 7, the effective filtering area and the volume are increased, so that the large amount of sundries in the sewage can be more effectively dealt with. This design ensures that the filter screen 7 can maintain good working condition under high flow condition and is not easy to be blocked.

[0035] The limiting plate 605 fixedly connected to the lower part of each lead screw 603 ensures the position control of the filter screen 7 during lifting to prevent the filter screen 7 from being damaged due to excessive downward movement, and maintains a proper working gap.

[0036] The working principle of the utility model is as follows:

[0037] In use, the user can adjust the relative position of the first water inlet 3 and the second water inlet 5 by rotating the upper cover plate 2 to control the size of the water inlet. This design enables the user to flexibly adjust the water inflow according to the rain condition. Through the overlapping and staggered design of the water inlets, the user can freely adjust the opening size of the water inlets according to the actual amount of rainwater, thereby improving the drainage efficiency and avoiding blockage caused by excessive rainwater.
