Description

Technical Field

[0001] This utility model relates to the technical field of dust suppression equipment for building construction, and in particular to a spray dust suppression device for building construction. Background Technology

[0002] Dust not only contains a large amount of particulate matter, but may also adsorb pollutants such as heavy metals and harmful microorganisms. These pollutants can seriously pollute the air quality at construction sites. At construction sites where effective dust suppression measures are not taken, the concentration of inhalable particulate matter and fine particulate matter in the air is often several times higher than the normal environmental standard. Construction workers who are exposed to such an environment for a long time are very likely to develop respiratory diseases, cardiovascular diseases and other health problems. At the same time, dust spreads with the wind and can also have adverse effects on the living environment of surrounding residents and traffic visibility. Therefore, a spray dust suppression device for construction sites is particularly needed.

[0003] However, existing spray dust suppression devices typically have a fixed cylinder length, making it difficult to flexibly adjust the spray distance according to the actual dust situation, resulting in poor dust suppression effect. Utility Model Content

[0004] The purpose of this utility model is to provide a spray dust suppression device for building construction, in order to solve the problem mentioned in the background art that the existing spray dust suppression devices usually have a fixed cylinder length, making it difficult to flexibly adjust the spray distance according to the actual dust situation, resulting in poor dust suppression effect.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a dust suppression spray device for building construction, comprising a cabinet, universal wheels fixedly connected to the lower surface of the cabinet, a water supply device installed on the inner surface of the cabinet, and a dust suppression mechanism provided on the upper surface of the cabinet. The dust suppression mechanism includes a base, a first motor, a rotating platform, a bracket, a rotating shaft, a second motor, a blower, a fan, a spray nozzle, a fixing frame, a water supply ring, a spray head, and a water supply pipe. An adjustment mechanism is provided on the inner surface of the dust suppression mechanism.

[0006] The adjusting mechanism includes a sliding groove, which is formed on the inner surface of the spray cylinder. A sliding block is slidably connected to the inner surface of the sliding groove. A locking block is fixedly connected to one end of the sliding block. A locking groove is formed on the inner surface of the blower cylinder. A spring is fixedly connected to the other end of the sliding block. A limiting post is fixedly connected to the inner surface of the sliding groove. A limiting semi-ring is fixedly connected to the outer surface of the spray cylinder. A limiting semi-ring groove is formed on the inner surface of the blower cylinder.

[0007] Preferably, the sliding block and the locking block are slidably connected to the limiting post, the inner surface of the sliding block and the locking block is provided with a limiting groove, and the outer dimension of the limiting post matches the inner dimension of the limiting groove.

[0008] Preferably, the card block and the card slot are slidably connected, the card slot is provided in multiple sets at equal intervals, one end of the card block is semi-circular, and the card slot is half arc-shaped and half cylindrical.

[0009] Preferably, there are two sets of limiting semi-rings and limiting semi-ring grooves, the outer dimension of the limiting semi-ring matches the inner dimension of the limiting semi-ring groove, and the limiting semi-ring is semi-circular.

[0010] Preferably, the base is mounted on the upper surface of the cabinet. A first motor is fixedly connected to the inner surface of the base. A rotating platform is fixedly connected to one end surface of the first motor. A bracket is fixedly connected to the upper surface of the rotating platform. A rotating shaft is rotatably connected to the inner surface of the bracket. A second motor is fixedly connected to one end surface of the rotating shaft. A blower is fixedly connected to the other end surface of the rotating shaft. A fan is fixedly connected to the inner surface of the blower. A spray tube is slidably connected to the inner surface of the blower. A fixing frame is fixedly connected to the inner surface of the spray tube. A water supply ring is fixedly connected to one side surface of the fixing frame. A spray head is fixedly connected to the outer surface of the water supply ring. A water supply pipe is fixedly connected to the outer surface of the water supply ring.

[0011] Preferably, the bracket and the rotating shaft are arranged symmetrically with respect to the central axis of the blower, and the fixing bracket is arranged in multiple sets on the inner surface of the spray tube.

[0012] Preferably, the spray cylinder is fixedly connected to the water supply ring via a fixing bracket, and multiple sets of spray heads are equally spaced on the outer surface of the water supply ring.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: This construction spray dust suppression device, through the setting of the adjustment mechanism, allows the semi-ring to slide stably within the semi-ring groove during use, enabling the spray cylinder to slide within the blower, thereby adjusting the extension length of the spray cylinder and changing the spray distance. When facing close-range dust, the cylinder body can be shortened for concentrated spray dust suppression; when the dust distance is far, the cylinder body can be extended so that the mist droplets can cover a wider area. By using a spring to push the locking block into the locking groove, the spray cylinder can be fixed in different positions. Compared with dust suppression devices with a fixed cylinder body, this significantly improves the flexibility of the dust suppression device and meets the dust suppression needs of different areas on the construction site.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figure 1-6 This utility model provides a technical solution: a dust suppression spray device for building construction, including a cabinet 1, with casters 2 fixedly connected to the lower surface of the cabinet 1, a water supply device 3 installed on the inner surface of the cabinet 1, and a dust suppression mechanism 4 provided on the upper surface of the cabinet 1. The dust suppression mechanism 4 includes a base 401, a first motor 402, a rotating platform 403, a bracket 404, a rotating shaft 405, a second motor 406, a blower 407, a fan 408, a spray tube 409, a fixing frame 410, a water supply ring 411, a spray head 412, and a water supply pipe 413. An adjustment mechanism 5 is provided on the inner surface of the dust suppression mechanism 4.

[0023] The adjusting mechanism 5 includes a sliding groove 501, which is formed on the inner surface of the spray cylinder 409. A sliding block 502 is slidably connected to the inner surface of the sliding groove 501. A locking block 503 is fixedly connected to one end of the sliding block 502. A locking groove 504 is formed on the inner surface of the blower 407. A spring 505 is fixedly connected to the other end of the sliding block 502. A limiting post 506 is fixedly connected to the inner surface of the sliding groove 501. A limiting semi-ring 507 is fixedly connected to the outer surface of the spray cylinder 409. A limiting semi-ring groove 508 is formed on the inner surface of the blower 407. Through the above structure... In this configuration, when it is necessary to adjust the position of the spray cylinder 409 relative to the blower cylinder 407, an external force is applied to the spray cylinder 409, causing the sliding block 502 to slide within the sliding groove 501 and the locking block 503 to disengage from the locking groove 504. At the same time, the spring 505 is compressed. When the spray cylinder 409 slides to the appropriate position, the external force is released, and the spring 505 pushes the locking block 503 to re-engage into the corresponding locking groove 504, thereby fixing the spray cylinder 409. The limiting post 506 guides the sliding of the sliding block 502 and the locking block 503, and restricts the semi-ring 507 from sliding within the limiting semi-ring groove 508, preventing the spray cylinder 409 from rotating.

[0024] Furthermore, the sliding block 502 and the locking block 503 are slidably connected to the limiting post 506. The inner surfaces of the sliding block 502 and the locking block 503 are provided with limiting grooves. The outer dimensions of the limiting post 506 match the inner dimensions of the limiting grooves. With the above structure, when the sliding block 502 and the locking block 503 slide during use, the limiting post 506 provides guidance for the sliding block 502 and the locking block 503, ensuring that the sliding block 502 and the locking block 503 can only move along the direction of the limiting post 506, avoiding deviation or shaking, making the adjustment process of the spray cylinder 409 smoother and more accurate, and preventing the locking block 503 from failing to accurately engage with the slot 504 due to sliding deviation.

[0025] Furthermore, the locking block 503 is slidably connected to the locking slot 504. Multiple sets of locking slots 504 are arranged at equal intervals. One end of the locking block 503 is semi-circular, and the locking slot 504 is half arc-shaped and half cylindrical. Through the above structure, the multiple sets of locking slots 504 provide multiple adjustable position selections during use. When adjusting the spray nozzle 409, the semi-circular locking block 503 is easier to slide out and slide into the locking slot 504. The shape of the locking slot 504, which combines arc and cylindrical shapes, can better match the locking block 503, making the locking of the locking block 503 in the locking slot 504 more stable.

[0026] Furthermore, two sets of limiting semi-rings 507 and limiting semi-ring grooves 508 are provided. The outer dimensions of the limiting semi-rings 507 match the inner dimensions of the limiting semi-ring grooves 508. The limiting semi-rings 507 are semi-circular. With the above structure, during use, the two sets of limiting semi-rings 507 are respectively embedded in the corresponding limiting semi-ring grooves 508. When the spray cylinder 409 slides relative to the blower cylinder 407, the limiting semi-rings 507 slides in the limiting semi-ring grooves 508, preventing the spray cylinder 409 from rotating. The spray cylinder 409 can only slide in a straight line, making the spray cylinder 409 more stable during adjustment.

[0027] Furthermore, the base 401 is installed on the upper surface of the cabinet 1. A first motor 402 is fixedly connected to the inner surface of the base 401. A rotating platform 403 is fixedly connected to one end of the first motor 402. A bracket 404 is fixedly connected to the upper surface of the rotating platform 403. A rotating shaft 405 is rotatably connected to the inner surface of the bracket 404. A second motor 406 is fixedly connected to one end of the rotating shaft 405. A blower 407 is fixedly connected to the other end of the rotating shaft 405. A fan 408 is fixedly connected to the inner surface of the blower 407. A spray tube 409 is slidably connected to the inner surface of the blower 407. A fixing frame 410 is fixedly connected to the inner surface of the spray tube 409. A water supply ring 411 is fixedly connected to one side surface of the fixing frame 410. A spray head 412 is fixedly connected to the outer surface of the ring 411, and a water supply pipe 413 is fixedly connected to the outer surface of the water supply ring 411. With the above structure, during use, the first motor 402 drives the rotating platform 403 to rotate, which drives the bracket 404, the blower 407 and the spray pipe 409 to rotate horizontally as a whole, changing the horizontal direction of the spray. The second motor 406 drives the rotating shaft 405 to rotate, which makes the blower 407 and the spray pipe 409 swing vertically, adjusting the elevation or depression angle of the spray. The fan 408 rotates to generate wind, which blows the mist water droplets sprayed by the spray head 412 on the water supply ring 411 out. The water in the water supply device 3 is transported to the water supply ring 411 through the water supply pipe 413, and then sprayed out by the spray head 412 to form a mist.

[0028] Furthermore, two sets of brackets 404 and rotating shafts 405 are symmetrically arranged around the central axis of the blower 407, and multiple sets of fixing brackets 410 are arranged on the inner surface of the spray tube 409. With the above structure, during use, the two sets of symmetrically arranged brackets 404 and rotating shafts 405 provide a stable support structure for the blower 407, making the blower 407 more balanced and stable during rotation. Multiple sets of fixing brackets 410 are evenly distributed on the inner side of the spray tube 409, firmly fixing the water supply ring 411, so that the water supply ring 411 remains stable during spraying.

[0029] Furthermore, the spray cylinder 409 is fixedly connected to the water supply ring 411 via the fixing bracket 410, and multiple sets of spray heads 412 are equally spaced on the outer surface of the water supply ring 411. With the above structure, during use, the spray cylinder 409 provides support and fixation for the water supply ring 411 via the fixing bracket 410, ensuring the stability of the position of the water supply ring 411. The equally spaced spray heads 412 enable the water flowing out of the water supply ring 411 to be sprayed out evenly in a mist form.

[0030] Working principle: The first motor 402 drives the rotating platform 403 to rotate, causing the bracket 404, blower 407, and spray nozzle 409 to rotate horizontally, changing the horizontal direction of the spray. The second motor 406 drives the rotating shaft 405 to rotate, causing the blower 407 and spray nozzle 409 to swing vertically, adjusting the elevation or depression angle of the spray. The fan 408 rotates to generate wind, blowing the mist-like water droplets sprayed from the spray head 412 on the water supply ring 411. Water from the water supply device 3 is transported to the water supply ring 411 through the water supply pipe 413, and then sprayed out by the spray head 412. The spray cylinder 409 forms a mist. When it is necessary to adjust the position of the spray cylinder 409 relative to the blower cylinder 407, an external force is applied to the spray cylinder 409, causing the sliding block 502 to slide in the sliding groove 501 and the locking block 503 to disengage from the locking groove 504. At the same time, the spring 505 is compressed. When the spray cylinder 409 slides to the appropriate position, the external force is released, and the spring 505 pushes the locking block 503 to re-engage in the corresponding locking groove 504, thereby fixing the spray cylinder 409. The limiting post 506 guides the sliding of the sliding block 502 and the locking block 503, and restricts the semi-ring 507 from sliding in the limiting semi-ring groove 508, preventing the spray cylinder 409 from rotating.

[0031] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
