Description

Technical Field

[0001] The present invention relates to the technical field of dust reduction devices, and particularly to an outdoor dust reduction device for building construction. Background Art

[0002] During the building construction process, in order to install outdoor facilities such as air conditioner outdoor unit brackets, solar water heaters, drying racks, and awnings, it is necessary to drill holes in the wall. After drilling, connecting pieces such as expansion bolts are inserted to firmly fix the facilities on the wall to ensure their stability and safety. For example, when installing an air conditioner outdoor unit, by drilling holes in the wall and using expansion bolts to fix the bracket, the air conditioner outdoor unit can be stably suspended outdoors and operate normally; However, when drilling holes in the outdoor wall, a large amount of dust and debris will be generated, which will affect the surrounding working environment. Moreover, during the drilling process, the dust may also get into the eyes of the construction workers, thereby reducing the construction efficiency.

[0003] Chinese Patent Publication No. CN215539513U discloses an outdoor dust reduction device for building construction, including a dust removal box. The left and right sides of the upper surface of the dust removal box are respectively rotatably connected to the lower surfaces of two connecting frames, and the inner walls of the two connecting frames are respectively rotatably connected to the outer surfaces of a suction fan and a sprayer. By setting the suction fan, exhaust pipe, filter bag, water pump, sprayer, connecting pipe b, and nozzle, the water pump extracts the water in the water tank and discharges the water into the sprayer through the other water outlet end and drain pipe a. The sprayer atomizes and sprays the water into the air with dust, and the water mist adsorbs the dust in the air. The suction fan extracts the water mist with dust outdoors and discharges the water mist with dust into the interior of the filter bag through the exhaust pipe. The filter bag filters the dust in the water mist, and the filtered water mist condenses into water and falls to the bottom of the dust removal box and enters the water tank through the water outlet pipe, solving the problem of excessive waste of water resources.

[0004] In the process of using the above patent literature, the dust reduction effect during the building construction process is achieved by spraying water.

Specific embodiments

[0019] In order to make the technical means, creative features, achieved purposes and effects of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0020] Embodiment 1, as shown in Figure 1 and Figure 2As shown in the figure, an outdoor dust reduction device for building construction includes a pistol drill 1. The output end of the pistol drill 1 is fixedly connected with a drill chuck. A limiting component 2 is threadedly installed on the rear part of the outer surface of the drill chuck. An upper cover component 3 is slidably installed on the upper front part of the inner surface of the limiting component 2. The lower end of the limiting component 2 is fixedly installed with an ash storage component 5. A lower cover component 4 is slidably installed on the lower part of the inner surface of the ash storage component 5. By using the upper cover component 3 and the lower cover component 4 in combination, when the pistol drill 1 drills the outdoor wall during building construction, it can automatically contract inward according to the perforation depth. And during the contraction process, it can also collect the slag and dust generated by drilling, avoiding the overflow of slag and dust when drilling the outer wall. The lower part of the outer surface of the ash storage component 5 is fixedly connected with a storage box 6. The lower end of the storage box 6 is fixedly connected with a micro vacuum cleaner 7. The output end of the micro vacuum cleaner 7 is located inside the storage box 6. By setting the ash storage component 5, it can cooperate with the lower cover component 4 to separately process the slag and dust generated by drilling when drilling the outdoor wall. And during the drilling process, the ash storage component 5 cooperates with the micro vacuum cleaner 7 to suck the dust into the inner cavity of the storage box 6. After the drilling work on the outdoor wall is completed, the ash storage component 5 can return to its initial state, thus achieving the effect of separately storing the slag and dust generated by drilling.

[0021] Both the pistol drill 1 and the drill chuck mentioned above are conventional settings in the prior art. In this solution, the pistol drill 1 and the drill chuck cooperate with each other, and their specific working principles are as follows: The drill chuck usually consists of three radially movable jaws, a tapered sleeve and a locking nut. When the sleeve is rotated, the internal conical surface pushes the jaws to move radially, and the drill bit shank is clamped through the internal teeth or grooves of the jaws. The clamping force is self-locked through the wedging effect of the conical surface to ensure that the drill bit does not loosen during rotation. The end of the output shaft of the pistol drill 1 has an external thread, which matches the internal thread of the drill chuck. During installation, it needs to be manually tightened to ensure the coaxiality of the two. When the built-in motor of the pistol drill 1 starts, the power is transmitted to the output shaft through the gear reduction box, driving the drill chuck to rotate. The drill chuck converts the rotational motion into cutting force through the clamped drill bit to achieve the drilling function. At this time, the drill chuck needs to bear the axial feed pressure and torque, and its structural strength and concentricity directly affect the drilling accuracy.

[0022] Therefore, both the pistol drill 1 and the drill chuck mentioned above are conventional designs in the prior art. Their specific installation methods, circuit connection methods and control methods are all conventional settings, and this solution will not elaborate on them in detail.

The rear ends of the four first guide rods 32 are fixedly connected to the front side wall of the inner surface of the concave groove 23. A first spring 33 is fixedly connected to each of the four corners of the rear end of the first concave plate 31. The four first springs 33 are respectively located outside the four first guide rods 32. The rear ends of the four first springs 33 are fixedly connected to the front side wall of the inner surface of the concave groove 23.

[0026] Furthermore, the ash storage component 5 includes an ash storage box 51 fixedly connected to the lower end of the housing 21. Main grooves 52 are provided on the left and right of the inclined surface at the front end of the ash storage box 51. A secondary groove 531 is provided at the lower edge of the inclined surface at the front end of the ash storage box 51. Five dust inlet holes 53 are linearly arranged in a linear array in the middle of the inclined surface at the front end of the ash storage box 51. A blocking component 54 is slidably installed on the inner surface of the ash storage box 51. A dust falling hole 55 penetrating the bottom wall of the secondary groove 531 and extending to the outside is provided in the middle of the bottom wall of the ash storage box 51. Five guide grooves 56 are linearly arranged on the left side wall and the right side wall of the inner surface of the ash storage box 51. Five sliding grooves 57 penetrating the rear end of the ash storage box 51 are provided in the middle of the front side of the inner surface of the ash storage box 51.

[0027] Furthermore, the lower cover component 4 includes a second concave plate 41. The second concave plate 41 is slidably connected to the inner surface of the cavity formed by the main groove 52 and the secondary groove 531. An inclined guide plate 42 is fixedly connected to the lower part of the rear side wall of the inner surface of the second concave plate 41. An extension plate 43 is fixedly connected to the lower part of the rear end of the second concave plate 41. A dust falling port 44 penetrating the lower end of the extension plate 43 is provided at the front part of the upper end of the extension plate 43. Two sliding holes are provided on the left and right of the rear end of the second concave plate 41. A second guide rod 45 is slidably connected to the inner surface of each of the two sliding holes on the same side. The rear ends of the four second guide rods 45 are fixedly connected to the rear side wall of the inner surface of the main groove 52. A second spring 46 is sleeved on the outer surface of each of the four second guide rods 45. The front ends of the four second springs 46 are fixedly connected to the rear end of the second concave plate 41. The rear ends of the four second springs 46 are fixedly connected to the rear side wall of the inner surface of the main groove 52.

[0028] When the output end of the pistol drill 1 drills a hole in the outdoor wall through the drill chuck and the drill bit, the front ends of the first concave plate 31 and the second concave plate 41 are simultaneously attached to the wall surface. Subsequently, the drill bit starts to drill the wall. During this process, the construction worker needs to hold the storage box 6 and the grip of the pistol drill 1 at the same time. During the drilling process, the drill bit continuously penetrates into the interior of the hole. Subsequently, the first concave plate 31 and the second concave plate 41 that are in contact with the wall surface will move backward. The same-side connection groove 24 communicates with the same-side main groove 52, and the main groove 52 communicates with the sub-groove 531. Therefore, the second concave plate 41 will slide into the cavity formed by the connection groove 24, the main groove 52, and the sub-groove 531 together, and the first concave plate 31 will directly slide into the inner cavity of the concave groove 23; When the first concave plate 31 and the second concave plate 41 slide backward, the first concave plate 31 will simultaneously squeeze the first spring 33 fixedly connected to its rear end, and the guide hole opened at its rear end and the first concave plate 31 slidingly connected to the inner cavity of the guide hole play a role in limiting and guiding. The second concave plate 41 will simultaneously squeeze the second spring 46 fixedly connected to its rear end, and the sliding hole opened at the rear end of the second concave plate 41 cooperates with the second guide rod 45 slidingly connected to its interior, and also plays a role in limiting and guiding, thus achieving the effect that the first concave plate 31 and the second concave plate 41 slide backward simultaneously as described above; When the first concave plate 31 and the second concave plate 41 move backward simultaneously, the moving distance is the depth of the drilled hole. The slag and dust generated during drilling all fall into the inner cavity of the second concave plate 41. An inclined guide plate 42 is fixedly connected to the front side wall of the inner surface of the second concave plate 42. When the slag falls on its surface, the inclined guide plate 42 can always make the slag slide into the inner cavity of the second concave plate 41. And during drilling, since the front ends of the first concave plate 31 and the second concave plate 41 are always attached to the wall surface, the drill bit can be wrapped during drilling, avoiding the overflow of slag and dust and affecting the surrounding environment. When the drilling is completed, the first concave plate 31 and the second concave plate 41 are no longer squeezed. Therefore, under the action of the first spring 33 and the second spring 46, the first concave plate 31 and the second concave plate 41 can return to their initial states.

[0029] Embodiment 3. On the basis of Embodiment 2, this embodiment aims to achieve the purpose of storing the slag and dust generated when drilling the outdoor wall in a partitioned manner.

[0030] Specifically, refer to Figure 1 、 Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 、 Figure 6 、 Figure 7 、 Figure 8 、 Figure 9 and Figure 10, the blocking component 54 includes five inclined baffles 541, the five inclined baffles 541 are respectively located in the inner cavities of the five ash inlets 53, connecting plates 542 are fixedly connected to the middle parts of the rear inclined surfaces of the five inclined baffles 541, transmission plates 543 are fixedly connected to the middle parts of the left ends and the middle parts of the right ends of the five connecting plates 542, partition plates 544 are fixedly connected to one sides of the front ends and the rear ends of the transmission plates 543 on the same side close to the left inner side wall and the right inner side wall of the inner surface of the ash storage box 51, and a rectangular plate 545 is fixedly connected to the rear ends of the five connecting plates 542 together.

[0031] Furthermore, the outer surfaces of the five connecting plates 542 are respectively slidably connected to the inner surfaces of the five sliding grooves 57, a filter plate 58 is fixedly connected to the middle part of the lower end of the ash storage box 51, and the filter plate 58 is located below the ash falling hole 55.

[0032] Furthermore, the transmission plates 543 on the same side are respectively slidably connected to the inner surfaces of the guiding grooves 56 on the same side, and the transmission plates 543 on the same side are fixedly connected to one ends of the inner surfaces of the concave plates two 41 on the same side close to each other.

[0033] Furthermore, the partition plates 544 on the same side are respectively in fit with the inner surfaces of the ash storage box 51 on the same side, the storage box 6 is fixedly connected to the lower end of the ash storage box 51, and the inner cavity of the storage box 6 communicates with the ash falling hole 55.

[0034] When drilling the outdoor wall, as can be seen from the above embodiments, the concave plate one 31 and the concave plate two 41 move backward with the drilling depth. When the concave plate two 41 moves backward, as can be known from the above, the transmission plates 543 on the same side are fixedly connected to one ends of the inner surfaces of the concave plates two 41 on the same side close to each other. Therefore, when the concave plate two 41 moves backward, the transmission plates 543 on the same side can be driven to move backward at the same time. And the connecting plates 542 are fixedly connected to the ends of the transmission plates 543 on the left and right sides close to each other, and the rectangular plate 545 is fixedly connected to the rear ends of the connecting plates 542 together. Therefore, when the connecting plates 542 move backward, the five inclined baffles 541 can be driven to leave the inner cavities of the corresponding ash inlets 53 at the same time. With the change of the drilling depth, the moving distance of the connecting plates 542 backward also changes accordingly; When the connecting plates 542 slide outwards in the inner cavities of the sliding grooves 57 on the same side, the transmission plates 543 fixedly connected to both sides of the connecting plates 542 will drive the concave plates two 41 to move backward continuously. When the concave plates two 41 move backward, the extension plates 43 fixedly connected to the rear ends of the concave plates two 41 will move backward in the inner cavities of the secondary grooves 531 at the same time. When the rear ends of the extension plates 43 contact the front side wall of the inner surface of the ash inlet 53, at this time, the ash falling ports 44 opened at the upper ends of the ash inlets 53 coincide with the ash falling holes 55 opened at the bottom wall of the ash storage box 51, and the filter plate 58 fixedly connected to the lower end of the ash storage box 51 is located below the ash falling holes 55; Therefore, during the drilling process, only by starting the micro-vacuum cleaner 7 can the micro-vacuum cleaner 7 start to pump air from the inner cavity of the storage box 6. Subsequently, during the air pumping process, larger debris will not be sucked into the inner cavity of the ash storage box 51 due to its own weight, while the dust will enter the inner cavity of the ash storage box 51 from the opening of the ash inlet 53, and then be adsorbed on the inner cavity of the filter plate 58 from the ash dropping hole 55. And part of the dust will enter the storage box 6 for storage. And when the connecting plate 542 moves backward in the inner cavity of the ash storage box 51, as described above, the same-side partition plates 544 are respectively in mutual contact with the inner surface of the same-side ash storage box 51. Therefore, when the partition plate 544 moves backward, the guide groove 56 can always be kept in a closed state, preventing dust from entering the inner cavity of the main groove 52 from the inner cavity of the guide groove 56, thereby improving the overall dust reduction effect; And when the drilling work on the outdoor wall is completed subsequently, only by taking out the drill bit from the drill hole, at this time, the concave plate two 41 and the concave plate one 31 will return to their initial states respectively under the action of the spring two 46 and the spring one 33. At the same time, the ash dropping port 44 no longer coincides with the ash dropping hole 55, and the inclined baffle 541 moves back to the inner cavity of the auxiliary groove 531 again, so that the whole device returns to its initial state, and finally the purpose of separate storage of debris and dust is achieved.

[0035] The above-mentioned micro-vacuum cleaner 7 is a conventional setting in the prior art, and its specific working principle is as follows: The micro-vacuum cleaner 7 mainly works by using the air negative pressure principle. It generates suction through the motor driving the fan to realize dust collection. The specific process is as follows: Generating suction: The micro-vacuum cleaner 7 is internally provided with a micro-motor. After the motor is powered on, it runs at a high speed, driving the fan blades to rotate rapidly. When the fan rotates rapidly, it will cause the air to flow rapidly, and then a air pressure difference is formed inside the micro-vacuum cleaner 7, that is, the pressure inside the micro-vacuum cleaner 7 is lower than the external atmospheric pressure. Under the action of this pressure difference, the external air will quickly rush into the vacuum cleaner, forming a strong suction force; Inhaling dust and debris: After the suction force is formed, the suction nozzle will suck the dust into the storage box 6 together with the air. The suction nozzle is designed to fit different cleaning scenarios and can better approach and suck the dust.

[0036] Therefore, the above-mentioned micro-vacuum cleaner 7 is a conventional design in the prior art, and its specific installation method, circuit connection method and control method are all conventional designs, and this solution will not elaborate on them in detail.

[0037] The above-mentioned filter plate 58 is a conventional setting in the prior art. The filter plate 58 mainly uses principles such as screening, inertial collision, interception, diffusion and electrostatic adsorption to separate the dust in the air from the air, so as to achieve the purpose of purifying the air; Sieving principle: The filter plate 58 is like a sieve with many tiny pores on its surface. When the dusty air passes through, dust particles larger than the pore size cannot pass through and are intercepted on the surface of the filter plate 58, thus being separated from the air. For example, in common coarse - efficiency filter plates 58, the pores are relatively large, and they can filter hair, large - particle dust, etc.; Inertial collision principle: When the air carrying dust passes quickly through the filter plate 58, dust particles with a larger mass maintain their original motion trajectory due to inertia and directly impact on the fibers of the filter plate 58 and are captured. For example, in an industrial environment, larger dust particles are easily filtered out due to inertial collision when passing through the filter plate 58; Interception principle: Some dust particles with sizes close to the pores of the filter plate 58 will come into contact with the fibers of the filter plate 58 and be intercepted when moving in a straight line with the air flow. This interception effect is better for filtering smaller - particle dust and is one of the important ways for medium - efficiency and high - efficiency filter plates 58 to function; Diffusion principle: For extremely tiny dust particles, they will perform random Brownian motion in the air. During the motion, these tiny particles come into contact with the fibers of the filter plate 58 and are adsorbed, thus achieving filtration. The diffusion principle plays a key role in the filtration of tiny pollutants such as bacteria and viruses by high - efficiency air filters HEPA; Electrostatic adsorption principle: Some filter plates 58 are charged through special treatment. The charged filter plate 58 can adsorb dust particles with opposite charges or polarize neutral dust particles and then adsorb them. Electrostatic adsorption can significantly improve the filtration efficiency and enhance the ability to capture tiny particles.

[0038] Therefore, the filter plate 58 is a conventional design in the prior art, and its specific size and shape can be adjusted according to actual production requirements. This solution will not elaborate on it in detail.

[0039] The above shows and describes the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above - mentioned embodiments. What is described in the above - mentioned embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
