Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression equipment in construction, specifically a simple and portable spraying device. Background Technology

[0002] With increasingly stringent requirements for dust control, wet methods are now mandatory for operations such as foundation pit excavation and slope spraying in construction projects to control construction dust pollution. Currently, commonly used dust suppression spraying solutions on construction sites mainly fall into three categories: First, fixed spraying systems attached to the perimeter fence. These systems are fixed in position and cannot move with dynamic operations such as excavation and slope spraying, limiting their dust suppression coverage. Second, tower crane spraying systems rely on the tower crane itself, and the spraying angle and coverage area are limited by the crane's boom length and operating radius, resulting in insufficient flexibility. Third, mobile mist cannons, while effective in dust suppression, have significant drawbacks: they require simultaneous connection to electrical wires and water pipes, leading to high material investment costs; their complex structure makes them prone to malfunctions, requiring specialized personnel with tools and spare parts for repairs; and their heavy weight makes them inconvenient to move in complex working environments such as foundation pits, hindering real-time adjustments to their position to follow the work surface. Therefore, how to solve the above-mentioned technical problems has become the subject of this utility model. Utility Model Content

[0010] III. Beneficial Effects Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Flexible and cost-controllable dust suppression: The device only needs to be connected to a water pipe to operate, eliminating the need for wiring. This reduces energy consumption and avoids the risk of electrical faults and leakage. The single unit is lightweight and can be moved by a single person. It can be plugged in and used immediately and can be adjusted in real time to follow the dynamic work surface such as foundation pit excavation and slope spraying, solving the problems of inconvenient movement of existing fog cannons and limited fixation of fences / tower cranes for spraying. 2. High adaptability: The support column can meet various needs through the cooperation of the telescopic rod and the adjustment hole, as well as the connection of the flexible hose. The height can be adjusted within a certain range; the bottom pipe can be adjusted at a certain angle through the rotating frame, and the top of the straight pipe and the bottom of the hose can be rotated to ensure that the rotation is not restricted. When the device is fixed in a complex construction site and the water pipes are connected in sequence, the position of the new adjustable bottom pipe can be adapted to facilitate the smooth connection of the inlet and outlet pipes. The spray heads around the rectangular pipe ensure all-round coverage to meet the dust suppression requirements of the construction site. 3. Reliable stability: The retractable stabilizing frame is inserted into the ground via four tapered stabilizing rods, in conjunction with a fixed... The fixed pole forms four or five points of support at the bottom, which improves the stability of placement in complex terrain; the two-way screw at the top of the telescopic pole drives the opening and closing of the stabilizing plate, which can easily tighten the rectangular tube from both sides to ensure the stability of the spraying state. 4. Convenient combination and use: Multiple devices can be connected in series using the U-shaped bottom tube; only the last one needs to be connected. By sealing the outlet of the end device, group spraying operations can be achieved. At the same time, the ball valve of a single device can be independently controlled to control the on / off state, taking into account both batch dust suppression and localized precise dust suppression needs. 5. Simple structure and easy maintenance: The overall structure has no complex electrical components, and the core components use threaded connections. Simple assembly methods such as connection and rotation connection allow for replacement without the need for professional tools or personnel after damage, reducing maintenance costs.
