Description

Technical Field

[0001] The present invention relates to the field of engineering management equipment, in particular to a construction site environment management device for engineering management. Background Art

[0002] In the field of engineering management, construction site environmental management is a crucial component in ensuring construction safety, improving efficiency, and minimizing impacts on the surrounding environment. Dust pollution, a common environmental issue on construction sites, not only harms the health of construction workers but can also negatively impact surrounding air quality, thus attracting widespread attention. To combat dust pollution on construction sites, a variety of control devices have emerged, with fog cannons being a common option. These devices atomize water into fine particles and use a fan to spray the atomized droplets into the air, where they combine with airborne dust particles to achieve dust reduction. Their wide coverage and immediate dust reduction effects have led to their widespread use at various construction sites. However, fog cannons have significant limitations in actual use. Because they achieve dust reduction through the spraying of large quantities of atomized water droplets, these droplets combine with dust and gradually settle to the construction site floor. Over time and with the accumulation of spray volume, the construction site floor becomes muddy due to the accumulation of water, polluting the ground environment. This polluted ground environment can cause numerous disruptions to construction work. For example, the muddy ground makes it difficult for construction vehicles to navigate, increasing the risk of vehicle stagnation and affecting the efficiency of material transportation. It can also cause inconvenience to construction workers as they move and work, potentially leading to safety incidents and hindering the smooth progress of construction. Therefore, in response to the above-mentioned problems existing in the existing fog cannons in the environmental management of construction sites, it is of great practical significance and application value to develop a construction site environmental management device that can effectively reduce dust without polluting the ground environment of the construction site, thereby avoiding interference with construction engineering management.

[0017] In order to further understand the content of the present invention, the present invention is described in detail with reference to the accompanying drawings and embodiments. It should be understood that the embodiments are merely for explaining the present invention and are not intended to limit the present invention.

[0018] Example 1 like Figure 1-5 As shown, this embodiment provides a construction site environment treatment device for engineering management, which includes a mobile body 100. The mobile body 100 is provided with a mounting seat 150. The mounting seat 150 is provided with a mounting groove 310. Further, the mounting seat 150 includes a bottom plate 410. The mounting groove 310 is provided in the bottom plate 410 and passes through the bottom plate 410. The two ends of the bottom plate 410 are provided with sealing plates 420 for sealing the openings at both ends of the mounting groove 310. A water storage seat 110 is provided in the mounting groove 310. The water storage seat 110 is fixedly provided in the mounting groove 310. A sealing sleeve 160 located in the mounting groove 310 is sleeved on the outer side wall of the water storage seat 110. The sealing sleeve 160 is used to seal the water storage seat opening 111. The sealing sleeve 160 is provided with a strip-shaped air inlet 161. The mounting seat 150 is provided with a fixing mechanism for fixing the sealing sleeve 160.

[0019] A drain pipe 240 is provided at the water storage seat 110 , and an end of the drain pipe 240 extends out of the sealing plate 420 . A sealing plug 250 is provided at the end of the drain pipe 240 extending out of the sealing plate 420 for sealing the drain pipe 240 .

[0020] A water storage seat opening 111 is also provided at the water storage seat 110; a filtering mechanism for filtering dust on the construction site is rotatably provided in the water storage seat 110, and the filtering mechanism includes a rotating rod 120, and mounting plates 130 are provided at both ends of the rotating rod 120. A connecting rod 210 is provided between the mounting plates 130 at both ends of the rotating rod 120, and the filtering mechanism also includes a filter net 140 covered at the connecting rod 210; a rotating rod blind hole 220 is provided at the rotating rod 120, and a plurality of strip through holes 230 communicating with the rotating rod blind hole 220 are provided at the rotating rod 120, and the strip through holes 230 are arranged along the length direction of the rotating rod 120; an exhaust mechanism for extracting air from the rotating rod blind hole 220 is also provided at the mobile body 100.

[0021] Before use, inject an appropriate amount of clean water into the water reservoir 110 (the water level should not exceed the lowest point of the rotating rod 120). Then, rotate the sealing sleeve 160 according to the actual usage. When the sealing sleeve 160 is rotated to the appropriate position, the sealing sleeve 160 is fixed to the mounting groove 310 using the fixing mechanism (fixing bolts 720 pass through the screw holes 710 of the sealing plate 420 and extend into the blind sleeve holes 810 of the sealing sleeve 160 to secure the sealing sleeve 160). It should be noted that the appropriate position mentioned here refers to adjusting the position of the strip-shaped air inlet 161 on the sealing sleeve 160, thereby adjusting the cross-sectional area and position of the air flow path formed between the strip-shaped air inlet 161 and the water reservoir opening 111.

[0022] Startup phase: Start centrifugal fan 170 and drive motor 440. Drive motor 440, through the meshing transmission of gear 450 and ring gear 430, drives the rotating rod 120 and the filter mechanism to rotate as a whole. Centrifugal fan 170 continuously extracts air from the rotating rod blind hole 220 through the pipe, connector 610, and sealing cover 460.

[0023] Filtration stage: After the air in the blind hole 220 of the rotating rod is extracted, negative pressure is formed, and the dust-laden air from the outside enters the space between the water storage seat 110 and the sealing sleeve 160 through the air flow channel formed between the strip air inlet 161 of the sealing sleeve 160 and the water storage seat opening 111; under the action of negative pressure, the dust-laden air passes through the filter 140 wrapped around the connecting rod 210, and the dust therein is intercepted by the filter 140 (the filter 140 periodically contacts the clean water in the water storage seat 110 when rotating with the rotating rod 120, and the dust is adsorbed by the water and retained in the water); the filtered clean air enters the blind hole 220 of the rotating rod through the strip through hole 230, and is finally extracted by the centrifugal fan 170 and discharged out of the device, thereby achieving the cleaning of the construction site environment.

[0024] The construction site environment control device for engineering management in this embodiment has the following advantages compared to existing fog cannons: Avoid muddy ground: Dust is handled by "wet filter 140 to absorb dust + water storage base 110 to store water". Clean water is only retained in the water storage base 110 and there is no need to spray it to the outside. This avoids water accumulation on the ground from the root and solves the problem of muddy ground caused by fog cannons.

[0025] High-efficiency dust filtration: Compared with fog cannons that rely on the random collision of water droplets and dust, this device actively inhales dust-laden air through negative pressure, forcing it to pass through the wet filter 140. The contact between dust and water is more complete, and the filtration efficiency is higher. At the same time, the rotating rod 120 drives the filter 140 to rotate continuously, which can avoid local blockage of the filter 140 and maintain a long-term stable filtration effect.

[0026] Flexible adaptation to construction site scenarios: The device is integrated into the mobile vehicle 100 and can be flexibly moved according to the dust-generating points on the construction site to adapt to different construction areas. The detachable design of the sealing sleeve 160 and the setting of the drain pipe 240 facilitate daily maintenance (such as cleaning sewage, replacing clean water, and cleaning the filter 140), adapting to the use needs of complex construction site environments.

[0027] In summary, the construction site environment control device for engineering management in this embodiment realizes the closed-loop treatment of "dust collection-filtration-pollution storage", which not only effectively controls the dust on the construction site, but also avoids damage to the construction ground environment.

[0028] Among them, by setting the rotating sealing sleeve 160, the cross-sectional area and position of the air flow channel formed between the strip air inlet 161 at the sealing sleeve 160 and the water storage seat opening 111 can be adjusted, so that when in use, the suction force and absorption direction of the device for dust can be adjusted according to the actual construction site environment, thereby further improving the applicability of the construction site environment management device for engineering management.

[0029] In this embodiment, in order to realize the driving of the rotating rod 120, the end of the rotating rod 120 away from the rotating rod blind hole 220 extends out of the water storage seat 110 and the sealing plate 420, and the end of the rotating rod 120 away from the rotating rod blind hole 220 and extending out of the sealing plate 420 is provided with a ring gear 430, and the sealing plate 420 is provided with a driving motor 440, and the rotating shaft of the driving motor 440 is provided with a gear 450 meshing with the ring gear 430.

[0030] The shaft of the drive motor 440 drives the gear 450, which meshes with the ring gear 430 at the end of the rotating rod 120. This steadily transmits the motor's rotational power to the rotating rod 120, ensuring uniform rotation of the rotating rod 120 and the filter mechanism (including the filter 140). This keeps the filter 140 continuously wet: the rotation of the filter mechanism periodically immerses the filter 140 in the clean water in the water reservoir 110, forming a "wet filter." The stable operation of the drive mechanism ensures uniform contact of all areas of the filter 140 with clean water, preventing localized drying that could reduce dust absorption capacity and maintaining efficient dust filtration.

[0031] Combine Figure 6 As shown, in this embodiment, in order to extract the air in the blind hole 220 of the rotating rod, the end of the rotating rod blind hole 220 at the rotating rod 120 extends out of the water storage seat 110 and the sealing plate 420, and the air extraction mechanism includes a sealing cover 460 arranged at the sealing plate 420 and used to seal the open end of the blind hole 220 of the rotating rod, a centrifugal fan 170 is provided at the mobile body 100, and a connecting head 610 is provided at the sealing cover 460, and the air inlet of the centrifugal fan 170 and the connecting head 610 are connected by a pipeline.

[0032] Centrifugal fan 170 continuously draws air from rotating rod blind hole 220 through the pipe, connector 610, and sealing cover 460, creating a stable negative pressure within rotating rod blind hole 220. Because strip-shaped through-hole 230 connects rotating rod blind hole 220 with the interior of water reservoir 110, a low-pressure zone forms within water reservoir 110. Dust-laden air from the outside is forcibly drawn in through strip-shaped air inlet 161 of sealing sleeve 160 due to the pressure differential, actively collecting dust from the construction site and resolving the low dust collection efficiency associated with traditional equipment that relies on natural airflow.

[0033] Combine Figure 7 、 8 As shown, the fixing mechanism includes a screw hole 710 provided on the sealing plate 420, and a sleeve blind hole 810 provided along the circumference of the side walls of both ends of the sealing sleeve 160. A fixing bolt 720 is provided in the screw hole 710, and the end of the fixing bolt 720 is used to pass through the screw hole 710 and extend into the sleeve blind hole 810 to fix the sealing sleeve 160. Figure 9 As shown, a roller groove 910 communicating with the mounting groove 310 is provided at the bottom plate 410 , and a plurality of supporting rollers 920 for supporting the sealing sleeve 160 are rotatably provided in the roller groove 910 .

[0034] The fixing bolt 720 passes through the screw hole 710 of the sealing plate 420 and extends into the sleeve blind hole 810 of the sealing sleeve 160. The sealing sleeve 160 is firmly fixed in the mounting groove 310 through mechanical locking, preventing the sealing sleeve 160 from being displaced when the device is running, thereby better improving the stability of the construction site environment management device for engineering management during use.

[0035] The blind holes 810 of the sealing sleeve 160 are arranged along the circumference. To adjust the orientation of the strip-shaped air inlet 161 or its relative position to the water reservoir opening 111, loosen the fixing bolts 720, rotate the sealing sleeve 160 to the desired angle (support rollers 920 assist in smooth rotation), and then retighten the fixing bolts 720 to insert them into the corresponding blind holes 810, achieving multi-angle positioning of the strip-shaped air inlet 161. This adjustability allows for flexible adaptation based on the source direction of dust on the construction site, improving the device's dust capture efficiency in specific areas.

[0036] The specific working principle of the construction site environment treatment device for engineering management in this embodiment is as follows: Preliminary preparation Pour an appropriate amount of clean water into the water reservoir 110 (the water level should not exceed the lowest point of the rotating rod 120), and seal the drain pipe 240 with the sealing plug 250 to ensure that a water storage space is formed in the water reservoir 110. Sleeve the sealing sleeve 160 onto the outer wall of the water reservoir 110 so that it is located in the mounting groove 310 and supported by the support rollers 920. Rotate the sealing sleeve 160 to adjust the orientation of the strip air inlet 161 according to the source of dust on the construction site until a suitable air flow path is formed between the strip air inlet 161 and the water reservoir opening 111. Tighten the fixing bolt 720 so that it passes through the screw hole 710 of the sealing plate 420 and extends into the sleeve blind hole 810 of the sealing sleeve 160. Secure the sealing sleeve 160 in the mounting groove 310 to complete the sealing and positioning of the device.

[0037] Device startup Start the drive motor 440 and the centrifugal fan 170: The rotating shaft of the drive motor 440 drives the gear 450 to rotate, and the gear 450 engages with the ring gear 430 at the end of the rotating rod 120, thereby driving the rotating rod 120 and the filter mechanism (including the filter 140) to rotate at a constant speed; the centrifugal fan 170 continuously extracts air from the blind hole 220 of the rotating rod through the pipeline, the connector 610 and the sealing cover 460, so that a negative pressure is formed in the blind hole 220 of the rotating rod.

[0038] Dust filtration Under the action of negative pressure, the dust-laden air from the outside enters the space between the water storage seat 110 and the sealing sleeve 160 through the strip-shaped air inlet 161 of the sealing sleeve 160, and then passes through the filter screen 140 that rotates with the rotating rod 120; the filter screen 140 is periodically immersed in the clean water of the water storage seat 110 during the rotation process to form a wet filter layer, and the dust particles in the dust-laden air are intercepted by the wet filter screen 140 and adsorbed in the water; the filtered clean air enters the blind hole 220 of the rotating rod through the strip-shaped through hole 230 of the rotating rod 120, and is finally drawn out by the centrifugal fan 170 and discharged out of the device.

[0039] Post-maintenance When sewage accumulates to a certain amount in the water storage seat 110 , the sealing plug 250 is opened to drain the sewage through the drain pipe 240 , and then the drain pipe 240 is re-sealed and fresh water is added.

[0040] In short, the above description is only a preferred embodiment of the present invention, and all equivalent changes and modifications made according to the scope of the patent application of the present invention should fall within the scope of the patent of the present invention.
