Description

Technical Field

[0001] This utility model relates to the technical field of prefabricated inspection wells, and in particular to prefabricated inspection wells for municipal use. Background Technology

[0002] Traditional municipal inspection wells are mostly constructed on-site using masonry or cast-in-place concrete, which has significant technical drawbacks: long construction cycles lead to extended road closures, affecting urban traffic; wet operations rely on manual labor, and the quality is greatly affected by the workers' skill level, easily resulting in problems such as well leakage and uneven settlement; material consumption is high, and the clay brick masonry process does not meet the requirements of a resource-saving society; on-site curing time is long, making it difficult to meet the needs of rapid construction in modern cities. Therefore, prefabricated assembled inspection wells are needed.

[0003] Currently, in existing prefabricated manholes, such as the patent with announcement number CN213358682U, this utility model discloses a prefabricated prefabricated manhole, which includes a protruding pipe, an upper manhole, a manhole connecting pipe and a lower manhole pipe arranged sequentially from top to bottom. The bottom of the lower manhole pipe is provided with multiple manhole branch pipes. The protruding pipe is fixedly connected to the top of the upper manhole. The top of the manhole connecting pipe is provided with a first limiting ring. The bottom of the upper manhole is provided with a first groove that cooperates with the first limiting ring.

[0004] It has been found that the locking operation of the existing manhole covers is not very convenient, and the air circulation and replacement in the manhole is not easy, which reduces the safety of personnel working inside. Utility Model Content

[0005] To solve the above-mentioned technical problems, this utility model provides a prefabricated assembled municipal inspection well that achieves air circulation within the inspection well, improves the safety of personnel operations, increases the efficiency of opening and closing the manhole cover, and enhances ease of use.

[0006] This utility model discloses a prefabricated assembled inspection manhole for municipal use, comprising a lower manhole body and an upper manhole body, with the upper manhole body positioned at the top of the lower manhole body. It also includes a locking device, a ventilation device, a notch, a protrusion, and a manhole cover. Ladders are installed on the inner walls of both the lower and upper manhole bodies. The notch is located at the top of the lower manhole body, and the protrusion is located at the bottom of the upper manhole body, with the notch and protrusion interlocking. An opening is provided at the top of the upper manhole body, and the manhole cover is rotatably installed at the opening via a hinge. Locking devices are installed on both the upper manhole body and the manhole cover to lock the manhole cover by rotation. A ventilation device is installed at the top of the upper manhole body to ventilate both the lower and upper manhole bodies. After rotating the manhole cover, personnel can enter the lower and upper manhole bodies via the ladder to work. Air is introduced into the lower manhole body through the ventilation device, and the air inside the lower and upper manhole bodies is discharged through the opening at the top of the upper manhole body, achieving air circulation within the inspection manhole and improving the safety of personnel. Personnel can quickly lock the manhole cover by operating the locking device, improving the efficiency of opening and closing the manhole cover and enhancing ease of use.

[0007] Preferably, the locking device includes a handwheel, a turntable, a connecting arm, a pin, and a kit. The handwheel is rotatably mounted on the top of the manhole cover, and the turntable is rotatably mounted on the bottom of the manhole cover. The bottom of the handwheel is concentrically connected to the turntable.

The kit is mounted on the outer wall of the manhole cover, and the pin is slidably mounted on the kit. A positioning groove is provided on the inner wall of the upper manhole body, and the front end of the pin is inserted into the positioning groove. When the manhole cover is closed at the opening of the upper manhole body by rotating the hinge, the operator rotates the handwheel to drive the turntable to rotate. After the turntable rotates, it drives the pin to slide through the connecting arm, thereby inserting the front end of the pin into the positioning groove to lock the manhole cover. The operator can quickly open the manhole cover by rotating the handwheel in the opposite direction, improving operational efficiency and convenience.

[0008] Preferably, the ventilation device includes a fan, a duct, a housing, and a filter. The fan is installed at the top of the upper well body, the top of the duct is connected to the fan, and the bottom of the duct extends into the bottom of the lower well body. The housing is installed at the top of the upper well body and is connected to the fan. The filter is installed on the air inlet end of the housing. The fan draws air into the housing, allowing outdoor air to pass through the filter and enter the duct, thereby enabling the duct to transport air to the lower well body, achieving the ventilation effect in the inspection well.

[0009] Preferably, it also includes a pump body and a water pipe. The pump body is installed at the top of the upper well body, the top of the water pipe is connected to the pump body, and the bottom of the water pipe extends into the bottom of the lower well body. When water accumulates in the lower well body, the pump body is turned on to pump out the water from the lower well body through the water pipe.

[0010] Preferably, it also includes protective net covers, with two sets of protective net covers respectively connected and installed at the bottom of the air duct and water pipe; improving the protective effect at the bottom openings of the air duct and water pipe.

[0011] Preferably, it also includes connectors, with multiple sets of connectors installed between the lower well body and the upper well body; improving the convenience of fixing the lower and upper well bodies after splicing.

[0012] Preferably, it also includes a buffer platform, which is set on the inner wall of the upper well body; by setting up the buffer platform, the convenience of stepping on the cushion when entering the upper well body is improved.

[0013] Preferably, it also includes a protective shell, which is installed at the top of the upper well body; this improves the protection of the blower, housing, filter screen and pump body.

[0014] Compared with the prior art, the beneficial effects of this utility model are as follows: After personnel rotate and open the manhole cover, they can enter the lower and upper manholes through the ladder to work. Air is supplied to the lower manhole through the ventilation device, and the air in the lower and upper manholes is discharged through the opening at the top of the upper manhole, thereby achieving air circulation in the inspection well and improving the safety of personnel. Personnel can quickly lock the manhole cover by operating the locking device, which improves the efficiency of opening and closing the manhole cover and enhances the convenience of use.
