Description

Technical Field

[0001] This utility model relates to the field of substation civil construction technology, and in particular to a dust removal device for substation civil construction. Background Technology

[0002] As a core hub in the power system, substations undertake the important tasks of voltage transformation, power distribution, and power transmission. Substation civil construction is a complex and critical project, encompassing multiple stages including earthwork excavation, foundation pouring, main structure construction, decoration, and equipment installation. During construction, earthwork excavation generates a large amount of dust, concrete mixing produces dust that disperses everywhere, and the handling and unloading of building materials further exacerbates dust dispersion. These construction activities result in a dusty and harsh environment at the construction site. Therefore, to ensure the normal operation of construction equipment and improve construction safety, effectively controlling dust pollution and reducing dust concentration at the construction site is particularly important during substation civil construction. Dust removal equipment for substation civil construction has thus emerged. In the past, various types of dust removal equipment were used to address dust problems during substation construction. Among them, baghouse dust collectors are a common type of dry dust collector, mainly consisting of a housing, filter bags, a cleaning system, an inlet and outlet, and a dust hopper. When dust-laden gas enters the dust collector through the inlet, the airflow velocity decreases, and some large dust particles fall directly into the dust hopper under gravity. As the remaining gas passes through the filter bags, dust is trapped on the surface of the bags, and the purified gas is discharged from the outlet through the tiny pores between the filter bag fibers. However, the filter bags of baghouse dust collectors are prone to... Problems arise because, due to their high water absorption, filter bags are prone to scaling in environments like substations where humidity can fluctuate significantly, leading to a substantial reduction in dust removal efficiency. To address this issue, technicians employed intelligent pulse cleaning technology, which can remove dust from the surface of the filter bags with a millisecond-level response speed. This non-contact cleaning technology not only improves cleaning efficiency but also avoids physical damage to the filter bags. However, strong electromagnetic interference at the construction site affects the control system of the electrical dust removal equipment, causing unstable operation and even malfunctions, resulting in poor filtration and cleaning effects and low practicality.

After cleaning, rotating the handle column in the opposite direction and then releasing the handle column causes the spring to return to its original state, so that the second half-gear and the first half-gear mesh, thereby restricting the filter plate and preventing it from rotating. This achieves the function of cleaning the dust on the top of the filter plate and enhances its practicality. Attached Figure Description

[0017] Please see the appendix Figure 3 - Appendix Figure 5 This utility model provides an embodiment of a dust removal device for substation civil construction, including a generating box 1. A cover plate 5 is fixedly connected to the top of the generating box 1, and an air guide hood 4 is fixedly connected to the top of the cover plate 5.

The filtration efficiency is improved through the synergistic effect of exhaust and airflow guiding. A dust collection mechanism 3 is provided at the bottom of the cover plate 5. The dust collection mechanism 3 is used for dust collection. The filtration mechanism 2 includes a protective box 201. The bottom of the protective box 201 is fixedly connected to the bottom of the inner wall of the generator box 1. A stepper motor 202 is fixedly connected to the bottom of the inner wall of the protective box 201. The stepper motor 202 provides a power source for the exhaust assembly 204 and the transmission assembly 205. It drives the fan 2041 to rotate and is driven by gears through a stable output speed. The exhaust assembly 204 is provided at the output end of the stepper motor 202. A protective cover 203 is fixedly connected to the top of the protective box 201.

It provides a closed working space for air purification and dust collection. A cover plate 5 is fixedly connected to the top of the generating chamber 1. The cover plate 5 serves two purposes: firstly, it seals the top of the generating chamber 1 to prevent unfiltered air from leaking out; secondly, it provides an installation base for the air guide hood 4 and the baffle 301 of the dust collection mechanism 3. A filter plate 7 is slidably connected to the inner wall of the cover plate 5. The filter plate 7 uses high-density chemical fiber filter material and is the core filtration component for achieving air purification.

A connecting plate 303 is fixedly connected to the right side of the outer wall of the connecting shaft 302. A connecting component 304 is provided on the right side of the connecting plate 303. A collection component 306 is provided at the bottom of the baffle 301. The collection component 306 includes an inclined plate 3061, the top of which is fixedly connected to the bottom of the baffle 301. A sliding cabinet 3062 is fixedly connected to the rear side of the generating box 1. The sliding cabinet 3062 provides a sliding track and installation space for the sliding collection cabinet 3063 and achieves a sealed connection with the generating box 1 to prevent dust from overflowing. The sliding collection cabinet 3063 is slidably connected to the inner wall of the sliding cabinet 3062. Specifically, the dust collection mechanism 3 includes a baffle 301, which is vertically installed at the bottom of the cover plate 5 to prevent dust from spreading into the generating chamber 1 during the rotation and cleaning of the filter plate 7, and to guide the dust to slide down towards the inclined plate 3061. A connecting plate 303 is fixedly connected to the right side of the outer wall of the connecting shaft 302. The connecting plate 303 serves as a transition connector between the connecting shaft 302 and the hollow column 3041, ensuring a stable connection and transmitting operating force. A connecting component 304 is provided on the right side of the connecting plate 303. The connecting component 304, through the elasticity of the spring 3042 and the sliding structure, realizes the extension and retraction and reset of the handle column 3043, providing a basis for unlocking and locking the filter plate 7. A collection device is provided at the bottom of the baffle 301. The dust collection component 306 is the final dust collection carrier. It guides the dust through the inclined plate 3061 and stores it in the sliding collection cabinet 3063, enabling convenient dust cleaning. The collection component 306 includes the inclined plate 3061, which is inclined at the front and lower at the back. It uses gravity to guide the dust sliding off the filter plate 7 towards the sliding cabinet 3062. The top of the inclined plate 3061 is fixedly connected to the bottom of the baffle 301. The sliding collection cabinet 3063 is slidably connected to the inner wall of the sliding cabinet 3062.

[0019] Please see the appendix Figure 3 - Appendix Figure 5The exhaust assembly 204 includes a drive gear 2042, the inner wall of which is fixedly connected to the output end of the stepper motor 202. A fan 2041 is fixedly connected to the inner wall of the drive gear 2042. The fan 2041 adopts a centrifugal blade structure, which generates negative pressure when rotating, driving the dusty air from the outside through the air guide shroud 4 into the generator box 1, forming a stable airflow circulation. A transmission assembly 205 is provided on the outer wall of the drive gear 2042. The transmission assembly 205 includes a chain 2051, the inner wall of which is meshed and softly connected to the outer wall of the drive gear 2042. A driven gear 2052 is meshed and connected to the right side of the inner wall of the chain 2051. The driven gear 2052 has the same specifications as the drive gear 2042. When rotating synchronously, it helps to enhance the negative pressure of the airflow, improve the intake efficiency of the dusty air, and avoid uneven airflow distribution inside the generator box 1. Specifically, the exhaust assembly 204 includes a drive gear 2042. The drive gear 2042 is fixed to the output end of the stepper motor 202, driving the fan 2041 to rotate synchronously. On the other hand, it transmits power to the driven gear 2052 through meshing with the chain 2051, realizing the coordinated operation of multiple components. The outer wall of the drive gear 2042 is provided with a transmission assembly 205.

The transmission assembly 205 includes a chain 2051, which is a flexible transmission component that realizes the power transmission between the drive gear 2042 and the driven gear 2052, adapting to the installation distance between the two.

[0020] Please see the appendix Figure 2 - Appendix Figure 4 The connecting component 304 includes a hollow column 3041. The left side of the hollow column 3041 is fixedly connected to the right side of the connecting plate 303. A spring 3042 is slidably connected to the inner wall of the hollow column 3041. The spring 3042 achieves automatic reset of the handle column 3043 through its own elasticity, providing power for the meshing and locking of the first half gear 3051 and the second half gear 3052. The handle column 3043 is slidably connected to the inner wall of the hollow column 3041. A locking component 305 is provided on the outer wall of the handle column 3043. The locking component 305 includes a first half gear 3051. The first half gear 3051 is fixed to the outer wall of the handle column 3043 and cooperates with the second half gear 3052 to form a complete gear structure. Locking is achieved through meshing. The inner wall of the first half gear 3051 is fixedly connected to the outer wall of the handle column 3043. The second half gear 3052 is slidably connected to the outer wall of the handle column 3043. Specifically, the connecting assembly 304 includes a hollow column 3041, which provides a sliding chamber for the spring 3042 and the handle column 3043, restricting their movement direction and ensuring structural stability. The left side of the hollow column 3041 is fixedly connected to the right side of the connecting plate 303. The handle column 3043 is slidably connected to the inner wall of the hollow column 3041, providing an operating grip for the operator. By sliding left and right and rotating, the filter plate 7 can be unlocked, rotated for cleaning, and relocked. The outer wall of the handle column 3043 is designed with... A locking component 305 is provided. The locking component 305 locks and unlocks the filter plate 7 in rotational state by engaging and disengaging the half gears, ensuring that the filter plate 7 remains stable during filtration and can rotate flexibly during cleaning. The inner wall of the first half gear 3051 is fixedly connected to the outer wall of the handle column 3043. The second half gear 3052 is slidably connected to the outer wall of the handle column 3043. The second half gear 3052 can slide along the outer wall of the handle column 3043. When it engages with the first half gear 3051, it locks the filter plate 7. When it disengages, it unlocks the filter plate 7, thus realizing rotation control.

[0021] Working principle: The airflow entering the air guide hood 4 is guided by the flow guide component 206, which slows down the flow rate and improves the filtration effect of the filter plate 7. The stepper motor 202 is turned on, which drives the exhaust component 204 to rotate. The drive gear 2042 is meshed with the chain 2051, which makes the transmission component 205 rotate at the same time, allowing outside air to enter the generator box 1. The air filtered by the filter plate 7 is discharged through the air outlet 6. Then the stepper motor 202 is turned off, and the dust collection mechanism 3 collects the dust and impurities on the top of the filter plate 7, which achieves the function of removing dust from the outside air and extends the service life of the filter plate 7, thus enhancing its practicality. Slide the handle column 3043 to the left, causing it to drive the second half gear 3052 to compress the spring 3042 and slide it into the hollow column 3041. This causes the second half gear 3052 and the first half gear 3051 to move away from each other, releasing the restriction. Then, rotate the pointer clockwise, causing the connecting shaft 302 to rotate simultaneously with the filter plate 7. This causes impurities on the top of the filter plate 7 to slide onto the top of the inclined plate 3061 and then into the sliding cabinet 3062. By periodically sliding the sliding collection cabinet 3063, the impurities are cleaned. After cleaning, rotate the handle column 3043 in the opposite direction and then release it. The spring 3042 returns to its original state, causing the second half gear 3052 to mesh with the first half gear 3051, thus restricting the filter plate 7 and preventing its rotation. This achieves the function of cleaning the dust on the top of the filter plate 7, enhancing its practicality.
