Abstract
Description
Technical Field
[0001] This utility model relates to the field of construction site dust control technology, and in particular to a dust suppression device for construction sites. Background Technology
[0002] As we all know, construction sites often generate dust during the construction process. The flying dust seriously affects the surrounding environment, so it is necessary to use a dust suppression spray system to reduce dust and protect the surrounding environment.
[0003] Most existing dust suppression spray systems at construction sites use a single nozzle for dust control. These systems typically employ a single nozzle mounted on a high pole, spraying water mist to moisten dust particles and promote their settling. However, when the nozzle is installed at a high position, it is susceptible to wind interference, causing it to sway. This not only interferes with its rotation but may also damage the nozzle structure. This results in uneven dust suppression coverage, affecting the overall dust control effect. Utility Model Content
[0004] The purpose of this invention is to address the shortcomings of existing technologies where the nozzles, when installed at a high position, are easily affected by wind and sway, which not only interferes with their rotation performance but may also damage the nozzle structure. Therefore, this invention proposes a dust suppression device for construction sites.
[0005] To achieve the above objectives, the present invention adopts the following technical solution:
[0006] Design a dust suppression device for construction sites, including a base, a water pump installed on one side of the top of the base, a connecting pipe installed on the other side of the top of the base, the water pump being connected to the connecting pipe, a first pipe connected to the top of the connecting pipe, a second pipe slidably mounted on the first pipe, a locking assembly connected to the outer side of the top of the first pipe, the locking assembly being connected to the second pipe, a fixed seat connected to the top of the second pipe, a water outlet pipe connected to one side of the fixed seat, a nozzle assembly connected to one end of the water outlet pipe via a sealed bearing, and a reinforcing assembly installed on the fixed seat, the reinforcing assembly being connected to the nozzle assembly;
[0007] The reinforcement component includes a guide groove formed on one side of the nozzle assembly. The guide groove is annular and coaxially arranged with the water outlet pipe. Both ends of the fixing base are provided with a pair of limiting posts. A connecting rod is slidably arranged on each pair of limiting posts. A stop bar is provided at one end of each connecting rod facing the guide groove. The two stop bars cooperate with the guide groove. An adjustment component is provided on one side of the fixing base. The adjustment component is connected to the other end of the two connecting rods.
[0008] Preferably, the middle area of both connecting rods is set as a ring, and the diameter of the ring is larger than the outer diameter of the second pipe.
[0009] Preferably, the adjustment assembly includes a frame fixed to one side of the fixed base, with threaded rods connected to both ends of the frame via bearings. Each of the two threaded rods is threaded through a corresponding connecting rod. A drive assembly is provided on the frame, and the drive assembly is connected to the two threaded rods.
[0010] Preferably, both stop levers have rotating balls mounted on them via bearings at the end facing the guide groove.
[0011] Preferably, a nitrided hardening layer is provided on the working surfaces of the guide groove and the two rotating balls.
[0012] Preferably, the locking assembly includes a fixing sleeve sleeved on the outer side of the top of the first pipe, and a connecting sleeve threadedly connected to the fixing sleeve. When the connecting sleeve is threadedly tightened onto the fixing sleeve, the inner wall of the connecting sleeve is pressed against the outer wall of the second pipe.
[0013] Preferably, the outer side of the connecting sleeve is provided with anti-slip texture.
[0014] Preferably, a sealing ring is provided at the bottom of the inner part of the fixed sleeve, and when the connecting sleeve is screwed onto the fixed sleeve, the vertical projection of the bottom of the connecting sleeve is located on the top of the sealing ring.
[0015] The dust suppression device for construction sites proposed in this utility model has the following advantages:
[0016] 1. By combining the two baffles with the guide groove, the wind load resistance of the nozzle assembly is improved during operation, making it less prone to shaking during the self-rotating spraying process. This avoids uneven dust collection caused by the swaying of the nozzle assembly, reduces damage to the connection between the nozzle assembly and the water outlet pipe, and extends the service life of the equipment.
[0017] 2. By rotating the ball within the guide groove, the sliding friction between the two stops and the guide groove is changed to rolling friction between the two rotating balls and the guide groove, significantly reducing frictional loss between the guide groove and the rotating balls and extending the service life of the equipment.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.
[0025] Example 1: Refer to Figure 1-5 A dust suppression device for construction sites includes a base 1, a water pump 2 installed on one side of the top of the base 1, a connecting pipe 3 installed on the other side of the top of the base 1, the water pump 2 being connected to the connecting pipe 3, a first pipe 4 being connected to the top of the connecting pipe 3, a second pipe 5 being slidably installed on the first pipe 4, a locking component being connected to the outer side of the top of the first pipe 4, the locking component being connected to the second pipe 5, a fixed seat 6 being connected to the top of the second pipe 5, a water outlet pipe 7 being connected to one side of the fixed seat 6, a nozzle assembly 8 being connected to one end of the water outlet pipe 7 via a sealed bearing, a reinforcing component being installed on the fixed seat 6, and the reinforcing component being connected to the nozzle assembly 8;
[0026] The reinforcement component includes a guide groove 12 formed on one side of the nozzle assembly 8. The guide groove 12 is annular and coaxially arranged with the water outlet pipe 7. Both ends of the fixing base 6 are provided with a pair of limiting posts 13. A connecting rod 14 is slidably arranged on each pair of limiting posts 13. A stop rod 15 is provided at one end of each connecting rod 14 facing the guide groove 12. The two stop rods 15 cooperate with the guide groove 12. An adjustment component is provided on one side of the fixing base 6. The adjustment component is connected to the other end of the two connecting rods 14. The adjustment component includes a frame 16 fixed on one side of the fixing base 6. Both ends of the frame 16 are connected to threaded rods 17 through bearings. The two threaded rods 17 are threaded through the corresponding connecting rods 14. A drive component 18 is provided on the frame 16. The drive component 18 is connected to the two threaded rods 17.
[0027] Usage process: After fixing the device on the plane of the area where dust suppression is needed on the construction site, connect the water pump 2 to the water supply pipe of the external device, start the drive assembly 18, the drive assembly 18 rotates with the two threaded rods 17, and drives the two connecting rods 14 to move between the pairs of limit posts 13 at both ends of the fixed seat 6, so that the two connecting rods 14 and the two stop rods 15 move together toward the guide groove 12, and after one end of the two stop rods 15 is engaged with the guide groove 12, simulate whether the nozzle assembly 8 works smoothly.
[0028] Loosen the locking component on the first pipe 4, allowing the second pipe 5 to slide inside the first pipe 4. After adjusting the nozzle assembly 8 to the preset height, tighten the locking component to fix the height of the second pipe 5 and the nozzle assembly 8.
[0029] Start water pump 2 to begin spraying to reduce dust. The operation can be repeated according to changes in the dust conditions on site to change the height and direction of the nozzle assembly 8, thereby improving the dust reduction effect of the device on the construction site.
[0030] This design ensures that when the nozzle assembly 8 is exposed to wind at a high position, the two baffles 15 and the guide groove 12 work together to prevent the nozzle assembly 8 from shaking during the self-rotating spraying process. This improves the wind resistance of the nozzle assembly 8 during operation, reduces water waste caused by the shaking of the nozzle assembly, reduces uneven dust settling, reduces wear at the connection between the nozzle assembly 8 and the water outlet pipe 7, and extends the service life of the equipment.
[0031] Example 2: In Example 1, the fixing seat 6 is installed at the top of the second pipe 5, and the connecting rod 14 at the bottom of the fixing seat 6 may interfere with the second pipe 5. An optimization is made based on Example 1, referring to... Figure 1-5 The middle area of both connecting rods 14 is designed as a ring, and the diameter of the ring is larger than the outer diameter of the second pipe 5. This allows the ring-shaped part of the connecting rod 14 to be penetrated by the second pipe 5, avoiding installation problems.
[0032] Example 3: An optimization based on Example 1, with reference to... Figure 4-5 The locking assembly includes a fixing sleeve 9 fitted on the outer side of the top of the first pipe 4, a connecting sleeve 10 threadedly connected to the fixing sleeve 9, the connecting sleeve 10 being threadedly tightened onto the fixing sleeve 9, the inner wall of the connecting sleeve 10 pressing against the outer wall of the second pipe 5, the outer side of the connecting sleeve 10 being provided with anti-slip texture, a sealing ring 11 being provided at the bottom inside the fixing sleeve 9, the connecting sleeve 10 being threadedly tightened onto the fixing sleeve 9, the vertical projection of the bottom of the connecting sleeve 10 being located on the top of the sealing ring 11, thereby increasing the sealing between the first pipe 4 and the second pipe 5, after all, leakage may occur at the connection between the first pipe 4 and the second pipe 5.
[0033] By rotating the connecting sleeve 10, the squeezing force of the connecting sleeve 10 on the second pipe 5 changes during the threaded engagement with the fixed sleeve 9. This allows the second pipe 5 to be adjusted relative to the first pipe 4, thereby adjusting the height of the nozzle assembly 8 at the top of the second pipe 5 and changing the height of the spray area of the device, thus enhancing the dust reduction effect of the device on the construction site.
[0034] Example 4: In Example 1, the two stop rods 15 and the guide groove 12 are in a state of sliding friction. As the nozzle assembly 8 rotates, the wear rate between the two stop rods 15 and the guide groove 12 is very fast, thus significantly reducing the supporting and limiting effect of the two stop rods 15 on the guide groove 12. Based on Example 1, optimizations are made, referring to... Figure 1-3 Both stop bars 15 have rotating balls 19 mounted on the end facing the guide groove 12 via bearings, and the working surfaces of the guide groove 12 and the two rotating balls 19 are provided with nitrided hardening layers.
[0035] By rotating the ball 19 within the guide groove 12, the sliding friction between the two stops 15 and the guide groove 12 is changed to rolling friction between the two rotating balls 19 and the guide groove 12, significantly reducing frictional loss between the guide groove 12 and the rotating balls 19. Furthermore, the nitrided hardening layer enhances the mechanical properties of the guide groove 12 and the rotating balls 19, further reducing mechanical wear between them, thereby improving the effectiveness of the device.
[0036] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
