DETAILED DESCRIPTION

[0034] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0035] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0036] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0037] Reference Figure 1 to Figure 7 , which is the first embodiment of the utility model, proposes an anti-blocking manhole cover, which is installed on the manhole barrel 1, including: a manhole seat 2 is arranged on the manhole barrel 1, and the manhole seat 2 has a filter 3; a cover body 4 is arranged on the manhole seat 2; a clamping block 5 is arranged on the cover body 4, the clamping block 5 is clamped with the filter 3, and the clamping block 5 is used to limit the cover body 4 from leaving the manhole seat 2.

[0038] In this embodiment, a cover body 4 is installed on the well seat 2. When in use, the well seat 2 is first installed on the well barrel 1, and then the cover body 4 is installed on the well seat 2. After being installed at the specified position, the snap-in block 5 on the cover body 4 will snap into the filter screen 3. The setting of the snap-in block 5 strengthens the connection between the cover body 4 and the well seat 2. In this way, even if sewage overflows and is sprayed out from the well barrel 1 in the opposite direction, the snap-in structure between the cover body 4 and the filter screen 3 can prevent the cover body 4 from detaching from the well seat 2, thereby ensuring the integrity of the well body, preventing the overflow port from further increasing after the cover body 4 detaches from the well seat 2, resulting in an increase in the overflow amount, and avoiding the danger that may be caused by the cover body 4 detaching from the well seat 2.

[0039] Furthermore, the clamping block 5 is slidably disposed on the cover body 4 , and further comprises: a sliding block 6 is slidably disposed on the clamping block 5 , the sliding block 6 is used to drive the clamping block 5 to slide, and the clamping block 5 slides into or away from the filter screen 3 .

[0040] In this embodiment, when the clamping block 5 slides, the sliding block 6 will drive the clamping block 5 to slide, and then enter the filter 3 to complete the clamping of the clamping block 5. Through the design of the sliding block 6, it can be ensured that multiple different clamping blocks 5 will be driven as a whole to be clamped, ensuring the uniformity of the action of the clamping block 5 and improving the strength of the clamping. Multiple clamping blocks 5 can be uniformly clamped or released by sliding a sliding block 6, simplifying the operation method.

[0041] Furthermore, it also includes: a rotating shaft 7 is rotatably set on the cover body 4; one end of the connecting line 8 is set on the sliding block 6, and the other end is wound around the rotating shaft 7; a steering shaft 9 is rotatably set on the cover body 4, the connecting line 8 abuts against the surface of the steering shaft 9, and the steering shaft 9 is used to change the direction of the connecting line 8; two ends of the first elastic member 10 are respectively set on the sliding block 6 and the cover body 4, and the first elastic member 10 is used to provide a force for the sliding block 6 to enter the filter 3.

[0042] In this embodiment, the movement of the sliding block 6 is controlled by the connecting wire 8. When the shaft 7 rotates, the length of the connecting wire 8 wound around the shaft 7 will change. Since the total length of the connecting wire 8 is fixed, the connecting wire 8 will slide the sliding block 6 in the direction of detaching from the filter screen 3 after the length wound around the shaft 7 increases, so that the sliding block 6 drives the clamping block 5 to detach from the filter screen 3, ensuring that the cover body 4 can be smoothly removed from the well seat 2. When the shaft 7 does not rotate, the first elastic member 10 will slide the sliding block 6 in the direction close to the filter screen 3, simplifying the installation steps and enabling it to automatically reset. The steering shaft 9 is used to change the direction of the connecting wire 8, so that the connecting wire 8 can better drive the sliding block 6 to move, preventing the resistance required for the movement of the connecting wire 8 from being too large, causing the connecting wire 8 to break, and ensuring that the device can operate stably.

[0043] Furthermore, the well seat 2 has a plurality of screw holes 11 , and also includes: embedded nuts 12 arranged on the cover body 4 ; connecting bolts 13 cooperate with the embedded nuts 12 and the screw holes 11 , and the connecting bolts 13 are used to reinforce the connection between the cover body 4 and the well seat 2 .

[0044] In this embodiment, the embedded nut 12 is embedded in the cover body 4 when the cover body 4 is produced. During installation, the screw hole 11 on the well seat 2 can be aligned with the embedded nut 12, and the screw hole 11 and the embedded nut 12 are connected by connecting bolts 13, thereby ensuring that the cover body 4 is better connected to the well seat 2, improving the connection strength between the cover body 4 and the well seat 2, further reducing the possibility of the cover body 4 being washed away due to excessive sewage overflow, and ensuring the safety of the cover body 4.

[0045] Furthermore, it also includes: a filter basket 14 is detachably arranged on the well seat 2 , and the filter basket 14 has a plurality of filter slots 15 , and the filter slots 15 penetrate the filter basket 14 .

[0046] In this embodiment, the filter basket 14 is located on the well seat 2. After the sewage enters the well seat 2 through the filter net 3, it will be filtered again by the filter basket 14. The double filtration method ensures that there are no large debris when the sewage enters the well barrel 1, which prevents the blockage of the well barrel 1 and improves the overall service life. At the same time, the filter basket 14 is detachable. Since the filter basket 14 is set inside the well seat 2, a large amount of debris filtered by the filter basket 14 will remain inside the filter basket 14. This part of the debris is difficult to clean. When cleaning, first remove the cover body 4, and then remove the filter basket 14 from the well seat 2, so that the filter basket 14 can be thoroughly cleaned, which improves the quality and efficiency of cleaning and ensures the cleaning effect.

[0047] Furthermore, it also includes: a plurality of anti-slip protrusions 16 are arranged on the top surface of the cover body 4.

[0048] In this embodiment, the anti-slip protrusion 16 is arranged on the surface of the cover body 4. The anti-slip protrusion 16 not only makes the cover body 4 more convenient during production and transportation, but also can warn passers-by with its unique shape after installation, avoiding damage to the manhole cover caused by passers-by stepping on it multiple times and avoiding danger.

[0049] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
