Technical Field

[0001] This utility model relates to the field of cleaning device technology, and in particular to a foundation pit cleaning device for highway engineering. Background Technology

[0002] Highway engineering refers to the surveying, measurement, design, construction, maintenance, and management of highway structures. Highway engineering includes roadbeds, pavements, bridges, culverts, tunnels, drainage systems, safety protection facilities, landscaping, and traffic monitoring facilities, as well as buildings, workshops, and other service facilities used for construction, maintenance, and monitoring. A foundation pit is an earthen pit excavated at the foundation design location according to the base elevation and foundation plane dimensions.

[0003] For example, Chinese utility model patent application number 202420359239.7 discloses a foundation pit cleaning device for highway engineering, including cleaning equipment. The cleaning equipment includes a base, and a water tank is fixedly connected to the top of the base. A pumping mechanism is installed on the top of the water tank; the pumping mechanism includes a water pump. This foundation pit cleaning device for highway engineering involves first inserting a second water pipe into a fixing ring, then rotating the second water pipe to connect the second thread with the first thread, then placing the second water pipe in the foundation pit, and starting the water pump. The water pump drives water to flow through the second water pipe, the first water pipe, the water pump, and the drain pipe into the base. At this time, the mesh screen can block leaves and most of the mud and sand, preventing them from clogging the water pipes or even entering the water pump and causing damage. It also facilitates the disassembly of the second water pipe for subsequent cleaning of the second water pipe and the mesh screen.

[0033] The stable placement mechanism 8 includes a rotating connecting pad 81, a carbon steel connecting sleeve 82 fixed to the outside of the rotating connecting pad 81, an anti-detachment groove 83 opened inside the mounting cover 4, an anti-detachment slider 84 slidably connected to the mounting cover 4 through the anti-detachment groove 83, a movable connecting pad 85 fixed to the outside of the anti-detachment slider 84, a positioning mounting plate 86 fixed to the outside of the carbon steel connecting sleeve 82, a carbon steel threaded post 87 fixed to the outside of the movable connecting pad 85, a carbon steel threaded sleeve 88 threadedly connected to the outside of the carbon steel threaded post 87, an arc-shaped groove opened on one side of the outer support sleeve 7, and the arc-shaped groove is adapted to the size of the cast iron mounting bracket 3, the rotating connecting pad 81 and the mounting cover 4 are rotatably connected by a rotating shaft, and a through hole opened inside the carbon steel connecting sleeve 82, the size of the through hole is adapted to the size of the movable connecting pad 85.

[0034] The collection locking mechanism 9 includes a shielding housing 91, a return spring 92 fixed to the inner bottom wall of the shielding housing 91, a mounting limit plate 93 connected to the top of the return spring 92, a movable connecting rod 94 fixed to the top of the mounting limit plate 93, a plastic handle 95 fixed to one end of the mounting limit plate 93, a guide groove 96 opened inside the shielding housing 91, a support connecting pad 97 fixed to the bottom of the mounting limit plate 93, a roller mounting housing 98 fixed to one side of the support connecting pad 97, a metal roller 99 rotatably connected inside the roller mounting housing 98 via a rotating shaft, a positioning hole adapted to the size of the movable connecting rod 94 opened inside the metal cover 12, the shielding housing 91 and the pit waste collection container 11 are fixedly connected, and the size of the guide groove 96 is adapted to the size of the plastic handle 95.

[0035] Working Principle: After cleaning the foundation pit, the user plugs in the foundation pit cleaning vacuum cleaner 1 and can operate it normally. The vacuum cleaner 1 works by using a motor to generate negative pressure, drawing in air and wet debris from the foundation pit. A filter separates the debris and impurities, finally expelling clean air. The wet debris is collected in a container. Both the foundation pit cleaning vacuum cleaner 1 and the vacuum head 2 are equipped with wheels for easy movement. After use, the vacuum cleaner 1 can be placed vertically inside the mounting cover 4. The bottom rollers of the vacuum cleaner head 2 and the vacuum cleaner head 1 can wipe away wet debris in the pit. Simultaneously, some wet debris falls into the installation cover 4 for centralized collection, preventing secondary contamination from subsequent movement and placement. When cleaning wet debris in the pit inside the installation cover 4, the carbon steel threaded sleeve 88 on the outside of the carbon steel threaded column 87 can be rotated. After the corresponding surface of the carbon steel threaded sleeve 88 moves away from the positioning mounting plate 86, the anti-disengagement slider 84 can be moved to slide within the anti-disengagement groove 83. This allows the anti-disengagement slider 84 to disengage the movable connecting pad 85 from the carbon steel connecting sleeve 82, thus releasing the lock on the carbon steel connecting sleeve 82. The user can then move the carbon steel connecting sleeve... The rotating connecting pad 81 is opened by means of 82, which facilitates the user to collect and clean the wet waste in the pit inside the installation cover 4. This device is equipped with a collection locking mechanism 9. After the collection container inside the pit cleaning vacuum cleaner 1 has collected a certain amount of wet waste in the pit, the collection container inside the pit cleaning vacuum cleaner 1 can be disassembled, and the wet waste in the pit can be poured into the pit waste collection container 11, thereby completing the centralized collection of wet waste in the pit. Then the collection container can be installed inside the pit cleaning vacuum cleaner 1 for continued use. When the metal cover 12 on the top of the pit waste collection container 11 is closed, first push down the plastic handle 95, so that the installation limit plate 93 drives the movable connecting rod 94. Move downwards, then slide the metal cover 12 to block the top opening of the pit waste collection container 11. After the metal cover 12 closes, release the plastic handle 95, allowing the return spring 92 to push the installation limit plate 93 vertically, and causing one end of the movable connecting rod 94 to be inserted into the metal cover 12 to lock the position of the metal cover 12. When the metal cover 12 needs to be opened, simply slide the plastic handle 95 downwards to allow one end of the movable connecting rod 94 to come out of the metal cover 12, making it easy to lock and unlock the metal cover 12. This is beneficial for the centralized collection of wet waste in the pit, and the cleaning and dumping of wet waste in the pit waste collection container 11 is also relatively simple, which is conducive to the waste cleaning after the pit is cleaned.

[0036] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
