Description
Technical Field
[0001] This utility model relates to the field of engineering construction technology, and more specifically, it relates to a dust suppression device for engineering construction. Background Technology
[0002] During industrial construction, dust pollution has become a significant factor affecting environmental quality and the health of surrounding residents. Various construction sites urgently need efficient dust suppression measures to meet increasingly stringent environmental protection requirements. Dust suppression needs vary significantly depending on the construction stage and weather conditions. For example, demolition projects require large-volume spraying to cover a wide area, while precision construction requires directional and precise spraying. This requires on-site staff to frequently change different models and functions of nozzles according to the actual situation. However, traditional dust suppression equipment generally uses threaded connections or snap-fit fixing to install nozzles. These connection structures usually require the use of special tools for disassembly and assembly, which is cumbersome and time-consuming, reducing the efficiency of equipment use and increasing the labor intensity of workers.
[0003] In complex and ever-changing outdoor construction environments, dust suppression equipment, as a commonly used environmental protection device, often requires its nozzles to be frequently replaced and adjusted under harsh conditions. The existing connection structure design of dust suppression devices lacks human-centered considerations. In dusty and confined working environments, operators find it difficult to quickly and accurately complete the installation and disassembly of nozzles, especially when working at heights, which further increases safety hazards. Utility Model Content
[0004] (a) Technical problems to be solved
[0005] In view of the problems existing in the prior art, this utility model provides a dust suppression device for engineering construction to solve the technical problems mentioned in the background art.
[0006] (II) Technical Solution
[0007] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression device for engineering construction, comprising a base, on which a dust suppression mechanism is provided, the dust suppression mechanism including a water tank and a nozzle, the water tank being installed on the top surface of the base, a water pump being connected to the outside of the water tank, a diversion pipe being connected to the output end of the water pump, a flexible hose being connected to the outer end of each diversion pipe, an output pipe being provided at the top of each set of flexible hoses, a quick-connect mechanism being provided on each set of output pipes, the quick-connect mechanism including a fixing sleeve and a limiting mechanism, the fixing sleeve being connected to the outer wall of the output pipe, a slider being slidably provided on the outer wall of the fixing sleeve, multiple sets of sliders being provided, each with a locking block fixed at its bottom end, a push block being fixed at the top of each set of sliders, a locking tube being inserted into the fixing sleeve, a locking groove being opened on the outer wall of the locking tube, the nozzle being fixed to the bottom end of the locking tube, and a limiting sleeve being slidably provided on the outer wall of the fixing sleeve.
[0008] The present invention is further configured such that the limiting mechanism includes an abutment sleeve and a sliding sleeve. The abutment sleeve is fixed to the outer wall of the limiting sleeve. The outer wall of the limiting sleeve is provided with a sliding groove, and multiple sets of sliding grooves are provided. The sliding sleeve slides within the multiple sets of sliding grooves. A push sleeve is fixedly provided on the inner side of the sliding sleeve. An elastic plate is fixedly provided on the outer wall of the sliding sleeve. Multiple sets of elastic plates are provided, and abutment blocks are fixedly provided on the inner side of each. A push ring is fixedly provided on the outer wall of the locking tube. This multi-mechanism forms a highly efficient linkage system. Through the thrust transmission between the push ring and the push sleeve and the elastic locking between the elastic plate and the abutment block, automatic positioning and locking during installation are achieved, greatly simplifying the operation steps and improving the installation efficiency and reliability in harsh environments.
[0009] The present invention is further provided with a compression spring connecting the top surface of the limiting sleeve and the fixing sleeve. This design forms a continuous and stable pressure source, ensuring that the limiting sleeve always maintains an appropriate preload on the snap-fit structure, preventing accidental loosening caused by vibration and impact. It also provides clear tactile feedback for operation, allowing the operator to clearly perceive the completion status of installation or disassembly.
[0010] The present invention is further provided that the outer wall of the abutting sleeve and the outer walls of the multiple sets of abutting blocks are all provided with rounded corners. This humanized design reduces the frictional resistance during the abutting process, allowing the abutting sleeve to smoothly push the elastic plate to deform, reducing the external force required for operation, while also reducing wear between components, extending the service life of the mechanism, and improving the overall durability of the device.
[0011] The present invention is further configured such that the outer wall of the fixed sleeve is provided with a movable groove, and the movable groove is provided in multiple sets and is slidably connected to multiple sets of push blocks respectively. This structure provides a precise guide track for the push blocks, ensuring that the push blocks maintain linear motion when moved under force, avoiding jamming and deflection, improving the reliability and durability of the locking mechanism, and the uniform distribution of multiple sets of movable grooves ensures the balance of the locking force.
[0012] The present invention is further configured such that a push spring is connected between the inner wall of the multiple sets of push blocks and the movable groove. This elastic element is designed to provide an automatic reset function for the snap-fit system, so that the push block can automatically return to the initial position after the external force is released, ready for the next snap-fit, reducing manual operation steps and improving continuous operation efficiency. At the same time, the elasticity of the push spring also enhances the firmness of the snap-fit state.
[0013] The present invention is further provided that the fixing sleeve is provided with a compression pad, which is disposed between the fixing sleeve and the clamping tube. The flexible sealing structure is compressed and deformed when the clamping tube is inserted into the fixing sleeve, forming an effective watertight seal, preventing high-pressure water from leaking from the connection, greatly improving the working reliability and service life of the equipment. At the same time, the compression pad also plays the role of buffering, shock absorption and dust prevention.
[0014] The present invention is further configured such that a support frame is fixedly provided on the top surface of the base, the support frame is fixedly connected to the diversion pipe, and a cylinder is fixedly provided on the base. The cylinder is provided in multiple sets, and the telescopic end is rotatably connected to a connecting rod. The top ends of the multiple sets of connecting rods are respectively rotatably connected to multiple sets of output ends. This design realizes the intelligent adjustment function of the nozzle position. Through the synergistic action of the cylinder and the connecting rod, the output pipe can be freely switched between the horizontal and vertical directions, which greatly increases the spray coverage area and adaptability, meets the diverse dust suppression needs under different working conditions, and improves the practical value and working efficiency of the equipment.
[0015] (III) Beneficial Effects
[0016] Compared with the prior art, this utility model provides a dust suppression device for engineering construction, which has the following beneficial effects:
[0017] 1. The dust suppression device for construction projects designed in this utility model adopts a quick-installation mechanism to connect the nozzle and the output pipe. Through the plug-in structure of the fixed sleeve and the clamping pipe, combined with the clamping method of multiple sets of clamping blocks and slots, the nozzle can be quickly installed and disassembled without the need for any special tools, which greatly improves the efficiency of the equipment. At the same time, the multi-point clamping design provides a stable and reliable connection, ensuring the safety of the nozzle and the spraying effect under high pressure. The setting of the compression pad effectively prevents water leakage at the connection and enhances the sealing performance of the device. The overall design significantly improves the practicality and working efficiency of the dust suppression device.
[0018] 2. The limiting mechanism of this utility model adopts a design combining an abutment sleeve and a sliding sleeve, and with the elastic snap-fit structure of the elastic plate and the abutment block, it forms a self-locking safety protection system, which effectively prevents the nozzle from accidentally falling off under high pressure. The compression spring provides continuous and stable pressure to the limiting sleeve, ensuring the reliability of the snap-fit state. The rounded corner design of the abutment sleeve and the abutment block makes the installation process smoother and reduces operating resistance. The linkage mechanism between the push ring and the push sleeve simplifies the installation steps, allowing operators to replace the nozzle with one hand. The design of this mechanism fully considers the harsh environment of the construction site and the ease of operation, greatly improving the practicality and safety of the dust suppression equipment.
[0019] 3. The support frame on the base provides stable support for the diversion pipe, ensuring the structural stability of the entire system. The combination design of multiple cylinders and connecting rods enables flexible adjustment of the output pipe, allowing the nozzles to switch freely between horizontal and vertical directions, greatly increasing the spray coverage area and adaptability. The integrated design of the water tank and water pump gives the equipment good independence and ease of movement. The use of hoses increases the flexibility of nozzle positioning, making the dust suppression effect more precise and effective. The entire device is compact in structure, complete in function, and easy to operate, significantly improving the efficiency and environmental protection effect of dust suppression in engineering construction, providing an ideal solution for dust control at construction sites.

[0029] Please see Figures 1-5 A dust suppression device for engineering construction includes a base 1, on which a dust suppression mechanism is provided. The dust suppression mechanism includes a water tank 2 and a nozzle 3. The water tank 2 is installed on the top surface of the base 1. A water pump 4 is connected to the outside of the water tank 2. A diversion pipe 5 is connected to the output end of the water pump 4. A flexible hose 6 is connected to the outer end of each diversion pipe 5. Each set of flexible hoses 6 has an output pipe 7 at its top. Each set of output pipes 7 is provided with a quick-installation mechanism. The quick-installation mechanism includes a fixing sleeve 8 and a limiting mechanism. The fixing sleeve 8 is connected to the outer wall of the output pipe 7. A slider 9 is slidably provided on the outer wall of the fixing sleeve 8. Multiple sets of sliders 9 are provided, and each set has a locking block 10 fixed at its bottom end. Each set of sliders 9 has a push block 11 fixed at its top end. A locking pipe 12 is inserted into the fixing sleeve 8. A locking groove 13 is opened on the outer wall of the locking pipe 12. The nozzle 3 is fixed to the bottom end of the locking pipe 12. A limiting sleeve 14 is slidably provided on the outer wall of the fixing sleeve 8.
[0030] The limiting mechanism includes an abutment sleeve 15 and a sliding sleeve 16. The abutment sleeve 15 is fixed to the outer wall of the limiting sleeve 14. The outer wall of the fixed sleeve 8 is provided with a sliding groove 17. Multiple sets of sliding grooves 17 are provided. The sliding sleeve 16 slides in multiple sets of sliding grooves 17. A push sleeve 18 is fixedly provided on the inner side of the sliding sleeve 16. An elastic plate 19 is fixedly provided on the outer wall of the sliding sleeve 16. Multiple sets of elastic plates 19 are provided, and abutment blocks 20 are fixedly provided on the inner side of each. A push ring 21 is fixedly provided on the outer wall of the locking tube 12. When the locking tube 12 is inserted, the push ring 21 pushes the push sleeve 18 to make the sliding sleeve 16 move in the sliding groove 17. At the same time, the sliding sleeve 16 drives the elastic plate 19 and the abutment block 20 to contact the abutment sleeve 15, forming a series of interlocking reactions to achieve the automatic locking function.
[0031] A compression spring 22 is provided between the top surface of the limiting sleeve 14 and the fixed sleeve 8. The compression spring 22 provides a preload force to the limiting sleeve 14. It is compressed and stores energy during the installation process, and releases energy during the locking process to push the limiting sleeve 14 back to its original position, forming continuous pressure on the snap-fit structure to ensure the stability of the connection.
[0032] The outer walls of the abutment sleeve 15 and the outer walls of the multiple sets of abutment blocks 20 are all provided with rounded corners. The rounded corner surfaces reduce the coefficient of friction and resistance torque between the contact surfaces, allowing the abutment sleeve 15 to slide smoothly over the abutment blocks 20, reducing operating resistance and component wear, and improving the operating efficiency and service life of the entire mechanism.
[0033] The outer wall of the fixed sleeve 8 is provided with a movable groove 23. Multiple sets of movable grooves 23 are provided and are slidably connected to multiple sets of push blocks 11 respectively. The movable groove 23 acts as a linear guide to constrain the movement direction of the push block 11, ensuring that the push block 11 can only move radially without deflection, thus ensuring the accuracy and reliability of the snap-fit.
[0034] Push springs 24 are connected between the inner walls of multiple push blocks 11 and the movable groove 23. The push springs 24 provide a constant inward pushing force to the push blocks 11, so that the push blocks 11 can automatically return to the initial position after unlocking, forming a self-resetting system, which simplifies operation and improves continuous use efficiency.
[0035] The fixed sleeve 8 is provided with a compression pad 25, which is located between the fixed sleeve 8 and the clamping tube 12. When the clamping tube 12 is inserted into the fixed sleeve 8, the compression pad 25 is compressed and deformed, filling the gap at the connection and forming a tight-fitting sealing interface to prevent liquid leakage and absorb vibration energy.
[0036] A support frame 26 is fixedly installed on the top surface of the base 1. The support frame 26 is fixedly connected to the diversion pipe 5. A cylinder 27 is fixedly installed on the base 1. The cylinder 27 is provided with multiple sets and the telescopic end is rotatably connected to the connecting rod 28. The top of the multiple sets of connecting rods 28 are rotatably connected to the multiple sets of output ends respectively. The telescopic movement of the cylinder 27 is converted into the rotational movement of the connecting rod 28, thereby realizing the angle adjustment of the output pipe and enabling the nozzle to spray in different directions to expand the coverage area.
[0037] In this embodiment, during use, water is pumped from the water tank 2 by the water pump 4, and then transported to multiple output pipes 7 through the diversion pipe 5. After that, it is sprayed by multiple nozzles 3 to reduce dust. The telescopic ends of multiple cylinders 27 retract and pull the connecting rods 28. The multiple connecting rods 28 pull the output pipes 7. The multiple hoses 6 connect the multiple output pipes 7 so that they move from the horizontal to the vertical direction, thereby adjusting the spraying area of the nozzles 3. When it is necessary to disassemble the nozzles 3, the abutment sleeve 15 is pushed to overcome the abutment force of multiple abutment blocks 20, so that multiple elastic plates 19 bend outward. When the abutment sleeve 15 is disengaged from the inner side of the multiple elastic plates 19, the abutment of the limiting sleeve 14 on the multiple push blocks 11 is released. The push blocks 11 are pushed to slide along the movable groove 23 by the multiple push springs 24 and the locking block 10 is pulled away from the locking groove 13 by the slider 9, thereby releasing the locking of the locking pipe 12. Then the locking pipe 12 can be removed from the fixing sleeve 8 to disassemble the nozzles 3.
[0038] More specifically, when installing the nozzle 3, the clamping tube 12 is inserted into the fixing sleeve 8 and the compression pad 25 is compressed. At the same time, the push ring 21 pushes the push sleeve 18, which drives the sliding sleeve 16 to slide along multiple sets of sliding grooves 17. Simultaneously, the sliding sleeve 16 pushes the abutment sleeve 15 through multiple sets of elastic plates and the abutment block 20. The abutment sleeve 15 drives the limiting sleeve 14 to slide and compress the compression spring 22. When the compression force of the compression spring 22 is greater than that of the multiple sets of elastic plates... When the 19 is subjected to force, the arc-shaped design of the abutment sleeve 15 and the abutment block 20 causes the abutment sleeve 15 to push the elastic plate 19 to bend outward and deform. Then the compression spring 22 pushes the limiting sleeve 14 to move to the inside of the multiple sets of elastic plates 19. At this time, the limiting sleeve 14 abuts against the outer wall of the multiple sets of push blocks 11, so that it squeezes the multiple sets of push springs 24 respectively. And the slider 9 pushes the card block 10 to engage in the card slot 13, fixes the card tube 12, and completes the installation of the nozzle 3.
[0039] In summary, during use or operation of the overall equipment: Water is pumped from the water tank 2 by the water pump 4, then transported through the diversion pipe 5 to multiple output pipes 7, and finally sprayed through multiple nozzles 3 for dust suppression. The telescopic ends of multiple cylinders 27 retract and pull the connecting rods 28, which in turn pull the output pipes 7. These output pipes 7 are then moved longitudinally via multiple hoses 6, adjusting the spray area of the nozzles 3. When it is necessary to adjust the spray area of the nozzles 3... During disassembly, the abutment sleeve 15 is pushed to overcome the abutment force of multiple abutment blocks 20, causing multiple elastic plates 19 to bend outward. When the abutment sleeve 15 disengages from the inner side of multiple elastic plates 19, the abutment of the limiting sleeve 14 against multiple push blocks 11 is released. The push blocks 11 are pushed to slide along the movable groove 23 by multiple push springs 24 and the locking block 10 is pulled away from the locking groove 13 by the slider 9, releasing the locking of the locking tube 12. Then the locking tube 12 can be disengaged from the fixing sleeve 8 to disassemble the nozzle 3.
[0040] However, when it is necessary to install the nozzle 3, the clamping tube 12 is inserted into the fixing sleeve 8 and the compression pad 25 is compressed. At the same time, the push ring 21 pushes the push sleeve 18, which drives the sliding sleeve 16 to slide along the multiple sets of sliding grooves 17. Meanwhile, the sliding sleeve 16 pushes the abutting sleeve 15 through the multiple sets of elastic plates and the abutting block 20. The abutting sleeve 15 drives the limiting sleeve 14 to slide and compress the compression spring 22. When the compression force of the compression spring 22 is greater than the force of the multiple sets of elastic plates 19, the arc-shaped design of the abutting sleeve 15 and the abutting block 20 causes the abutting sleeve 15 to push the elastic plate 19 to bend outward. Then, the compression spring 22 pushes the limiting sleeve 14 to move to the inside of the multiple sets of elastic plates 19. At this time, the limiting sleeve 14 abuts against the outer wall of the multiple sets of push blocks 11, so that it compresses the multiple sets of push springs 24 respectively. The slider 9 pushes the clamping block 10 to engage in the clamping groove 13, fixing the clamping tube 12 and completing the installation of the nozzle 3.

These will not be elaborated on here. For all the fixed connections mentioned above, welding is the preferred option.
