Description

Technical Field

[0001] The utility model relates to the field of anti - falling devices, in particular to an anti - falling device for a drainage inspection well in municipal engineering. Background Technique

[0002] An inspection well is a manhole established on a drainage pipeline system for inspecting and cleaning pipelines; at the same time, it also plays the role of connecting pipe segments and ventilating the pipeline system, and is set at segmented intervals according to the pipeline diameter and the types of rainwater and sewage.

[0003] For the existing anti - falling device, only the pre - fabricated wellhead pipeline needs to be placed at the wellhead of the well body and fixed by expansion bolts. The installation is convenient. When the inspection well is in normal use, rainwater will flow into the well body through the gap between the positioning ring and the protection plate, without affecting the use of the inspection well. Under the double protection of the protection plate and the protection net, when an external object at the wellhead falls, the falling object will first fall onto the protection plate. Under the action of the elastic member, the reinforcing rib and the protection plate move relatively up and down to weaken the falling force, protect the safety of the falling object, and prevent human body from being injured.

[0004] However, the existing anti - falling device is installed inside the wellhead by engaging multiple expansion bolts. Due to environmental influence, the expansion bolts will expand and contract thermally, causing the bolts to loosen and affecting the installation stability of the anti - falling device. At the same time, when the anti - falling device is installed inside the wellhead and sewage flows for a long time, dirt will remain on the lower surface of the anti - falling device, causing the anti - falling device to breed bacteria and produce odors. However, it needs to be disassembled for cleaning, which affects the convenience of using the anti - falling device. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti - falling device for a drainage inspection well in municipal engineering, which is used to solve the problems that the existing anti - falling device is installed inside the wellhead by engaging multiple expansion bolts. Due to environmental influence, the expansion bolts will expand and contract thermally, causing the bolts to loosen and affecting the installation stability of the anti - falling device. At the same time, when the anti - falling device is installed inside the wellhead and sewage flows for a long time, dirt will remain on the lower surface of the anti - falling device, causing the anti - falling device to breed bacteria and produce odors. However, it needs to be disassembled for cleaning, which affects the convenience of using the anti - falling device.

[0006] Therefore, the utility model provides an anti - falling device for a drainage inspection well in municipal engineering, including a well body, a side - mounting mechanism and a cleaning mechanism. An inspection groove is opened inside the well body, and a side - mounting mechanism for quickly disassembling and assembling the anti - falling component is arranged on the inner walls of both sides of the inspection groove. The lower end on the right side of the side - mounting mechanism is provided with a cleaning mechanism for brushing the dirt on the anti - falling component.

[0007] Preferably, the side-mounted mechanism includes a fall prevention net and a slot. Side plates are installed on both side walls of the fall prevention net, and clamping grooves are formed on the side walls of the side plates. The slots are symmetrically formed on both side walls of the well slot. Screws are installed in the slots. A clamping plate is sleeved on the outer wall of the screw, and the clamping plate is slidably installed in the slot. An inner slot is formed on the outer side of the slot in the transverse direction. A first bevel gear is installed on the inner wall of one end of the inner slot close to the slot, and a second bevel gear is installed on the upper inner wall of the inner slot. The upper end of the second bevel gear is connected to a knob.

[0008] Preferably, the cleaning mechanism includes a sliding groove. The sliding groove is formed on the lower side wall of the side plate. A sliding plate is installed in the sliding groove. Limiting grooves are symmetrically formed on both sides of the sliding groove. Limiting plates are symmetrically installed on both sides of the sliding plate and are slidably embedded in the sliding groove. A gear is installed on the upper side wall of the sliding plate. The right end of the gear is connected to a motor. A side groove is formed on the upper side wall of the sliding groove. A toothed plate is installed in the side groove. A scraping plate is installed at the lower end of the sliding plate.

[0010] Preferably, the cross-sectional dimension of the clamping plate meshes with the cross-sectional dimension of the clamping groove.

[0011] Preferably, the cross-sectional dimension of the limiting groove fits with the cross-sectional dimension of the limiting plate.

[0012] Preferably, the toothed plate meshes with the gear.

[0013] 1.
