Description

Technical Field

[0001] This invention relates to the field of anti-slag-hanging and slag-churning protection technology, and in particular to a protection device. Background Technology

[0002] Slag trapping and slag sluice protection is a comprehensive set of protective measures for slopes, spoil heaps, and construction slopes. It aims to reduce loose rock sluice trapping on slopes at the source, intercept debris rolling downhill, and divert water runoff to prevent mudslides or impact damage. Active slag trapping points are eliminated through smooth blasting, slope clearing, or the use of covering netting and hanging panels. Passive structures such as retaining walls, flexible protective nets, and earthen embankments are installed at the slope toe or platform to intercept slag sluice ...

[0003] In existing technologies, methods such as precision blasting, slope clearing, shotcreting with wire mesh, and spraying are used to actively eliminate or cover sources of debris such as loose rocks and pits on the slope. Subsequently, intercepting structures such as retaining walls, passive flexible nets, and earthen embankments are installed in the lower and middle parts of the slope or on various platforms to gradually slow down and block the rolled-down debris. Simultaneously, drainage ditches at the top of the slope, rapid flow channels on the slope surface, and drainage ditches at the toe of the slope are used to divert surface runoff and prevent secondary landslides caused by water carrying debris. Debris collection platforms or pits are set up at the bottom of the retaining structure, and manual or mechanical removal of accumulated debris is arranged regularly. The deformation and blockage of key components such as protective nets and walls are also checked, forming a closed-loop operation and maintenance management system.

[0004] After prolonged use, drainage holes need to be installed at the bottom of the retaining wall to prevent water pressure buildup, and slag discharge gates are required to clean up accumulated slag. However, gravel or mud can get stuck in the drainage holes and slag discharge gate tracks, preventing the gates from opening and water from draining. This requires manual cleaning, which is time-consuming and labor-intensive, reduces the continuity of the device's use, and is not conducive to its widespread adoption in practice. Summary of the Invention

[0005] The purpose of this invention is to provide a protective device to alleviate the problem that gravel or mud gets stuck in the drain hole and the slag discharge gate groove when using existing protective devices, requiring manual cleaning.

[0006] To solve the above-mentioned technical problems, the technical solution provided by the present invention is as follows: A protective device includes: a first protective plate, wherein the first protective plate is provided with a slag-blocking and cleaning mechanism; The slag-blocking and cleaning mechanism includes a slag-blocking and beating assembly, which includes a top plate, a transmission structure, and a beating structure. The top plate is fixedly installed on the top of the first baffle plate. One end of the transmission structure is connected to the top plate, and the other end is connected to the beating structure. The top plate is subjected to the impact force of the slag and stone, which is transmitted to the striking structure through the transmission structure, causing the striking structure to swing and strike the first guard plate.

[0007] Furthermore, the transmission structure includes a first transmission part and a second transmission part that are connected by transmission. The first transmission part is arranged in a vertical direction, and the second transmission part is arranged in a horizontal direction. The second transmission part is used to convert the linear motion of the first transmission part into rotational motion.

[0008] Furthermore, the first transmission part includes a fixed block, a connecting spring, a telescopic rod, and a rack. The top end of the fixed block is connected to the top plate, and the bottom end is connected to the top end of the telescopic rod. The bottom end of the telescopic rod is connected to the rack. The connecting spring is wound around the telescopic rod, and the bottom of the rack is connected to the second transmission part.

[0009] Furthermore, the second transmission part includes a connecting plate, a rotating rod, and a gear. The connecting plate is fixedly connected to the first baffle plate. The rotating rod is rotatably mounted on the inner wall of the connecting plate. The gear is mounted on the rotating rod and meshes with the rack.

[0010] Furthermore, the striking structure includes a fixed ring, a receiving frame, and a striking hammer. The fixed ring is sleeved on the rotating rod, and the striking hammer is connected to the fixed ring through the receiving frame. The striking hammer is capable of swinging and striking the first guard plate.

[0011] Furthermore, a slide rail is fixedly installed at the bottom of the first guard plate, and a sliding door is slidably connected to the slide rail. The hammer is positioned above the slide rail.

[0012] Furthermore, the slag-blocking and cleaning mechanism also includes a synchronous cleaning component, which is connected to the top plate and is used to clean the slide rail.

[0013] Furthermore, the synchronous cleaning component includes a rectangular block, a placement rack, and a cleaning block. The top end of the rectangular block is connected to the top plate, and the bottom end is connected to the placement rack. The cleaning block is installed on the placement rack and is positioned on the slide rail.

[0014] Furthermore, the first guard plate is fixedly equipped with a first guide block and a second guide block, the first guide block being slidably connected to the rack, and the second guide block being slidably connected to the rectangular block.

[0015] Furthermore, a drain pipe is fixedly installed on the first baffle plate, and the drain pipe is located above the sliding door.

[0016] This invention can bring at least the following beneficial effects: By incorporating a slag-blocking and striking component, the efficient conversion and utilization of the impact energy of the slag chute is achieved. When slag falls and impacts the roof plate, the roof plate, through a transmission structure, acts on the striking structure, causing the striking structure to swing and strike the first baffle plate. When the striking position of the striking structure is outside the sliding door's rail, automatic slapping and cleaning of the rail is achieved, effectively preventing slag from getting stuck in the rail. This solves the problem in existing technologies where the slag discharge door cannot be opened normally due to slag blockage, reduces the frequency and difficulty of manual cleaning, improves the continuity of the device's use, and facilitates more efficient operation.

[0026] The following detailed description of some embodiments of the present invention is provided in conjunction with the accompanying drawings. Unless otherwise specified, the following embodiments and features described herein can be combined with each other.

[0027] Example 1 This invention provides a protective device, including: a first protective plate 1, the first protective plate 1 being provided with a slag-blocking and cleaning mechanism; the slag-blocking and cleaning mechanism includes a slag-blocking and striking assembly 12, the slag-blocking and striking assembly 12 including a top plate 1201, a transmission structure and a striking structure, the top plate 1201 being fixedly disposed on the top of the first protective plate 1, one end of the transmission structure being connected to the top plate 1201, and the other end being connected to the striking structure via a transmission mechanism; the top plate 1201 is subjected to the impact force of slag and stone, which acts on the striking structure through the transmission structure, causing the striking structure to swing and strike the first protective plate 1.

[0028] By setting up the slag-blocking and slapping component 12, the efficient conversion and utilization of the impact energy of the slag chute is achieved. When the slag falls and impacts the top plate 1201, the top plate 1201 acts on the slapping structure through the transmission structure, causing the slapping structure to swing and strike the first baffle plate 1. When the striking position of the slapping structure is outside the slide rail 9 of the sliding door 10, the slide rail 9 can be automatically slapped and cleaned, effectively preventing slag from getting stuck in the slide rail 9. This solves the problem in the prior art where the slag discharge door cannot be opened normally due to slag jamming, reduces the frequency and difficulty of manual cleaning, improves the continuity of the device's use, and is conducive to more efficient operation.

[0029] In an optional embodiment, the transmission structure includes a first transmission part and a second transmission part connected by transmission. The first transmission part is arranged in a vertical direction, and the second transmission part is arranged in a horizontal direction. The second transmission part is used to convert the linear motion of the first transmission part into rotational motion.

[0030] The impact force of falling slag and rock hitting the roof plate 1201 is transmitted vertically through the first transmission unit and then horizontally through the second transmission unit. Simultaneously, the linear motion of the first transmission unit is converted into rotational motion, thus realizing the oscillating motion of the striking structure. The vertical separation of the first and second transmission units saves space while ensuring effective transmission.

[0031] In an optional embodiment, the first transmission unit includes a fixed block 1202, a connecting spring 1203, a telescopic rod 1204, and a rack 1205. The top end of the fixed block 1202 is connected to the top plate 1201, and the bottom end is connected to the top end of the telescopic rod 1204. The bottom end of the telescopic rod 1204 is connected to the rack 1205. The connecting spring 1203 is wound around the telescopic rod 1204, and the bottom of the rack 1205 is connected to the second transmission unit.

[0032] See Figure 5 The side of the top plate 1201 is attached to the back of the first guard plate 1. The upper surface of the fixing block 1202 is fixedly installed to the lower surface of the top plate 1201. The top end of the telescopic rod 1204 is fixedly installed to the lower surface of the fixing block 1202. A connecting spring 1203 is provided on the telescopic rod 1204 to provide elastic force for the telescopic rod 1204 to return to its original position. The upper surface of the rack 1205 is fixedly installed to the bottom end of the telescopic rod 1204, and the bottom of the rack 1205 is connected to the second transmission part for transmission.

[0033] Furthermore, the second transmission unit includes a connecting plate 1206, a rotating rod 1207, and a gear 1208. The connecting plate 1206 is fixedly connected to the first guard plate 1. The rotating rod 1207 is rotatably mounted on the inner wall of the connecting plate 1206. The gear 1208 is mounted on the rotating rod 1207 and meshes with the rack 1205.

[0034] See Figure 6 The outer surface of gear 1208 meshes with the back of rack 1205. A connecting plate 1206 is fixedly installed on the back of the first guard plate 1. A rotating rod 1207 is rotatably installed on the inner wall of the connecting plate 1206. The outer surface of the rotating rod 1207 is fixedly installed with the inside of gear 1208. The connecting plate 1206 provides stable support for the rotating rod 1207. The rotating rod 1207 is rotatably installed on the inner wall of the connecting plate 1206, ensuring its smooth rotation.

[0035] The slag-blocking and tapping assembly 12 cleverly converts the pressure generated by falling slag into meshing force. When slag falls and impacts the top plate 1201, the top plate 1201 moves downward under force, causing the fixed block 1202 to move downward, which in turn compresses the connecting spring 1203. The telescopic rod 1204 and the rack 1205 also move downward. The movement of the rack 1205 drives the gear 1208 to rotate. Utilizing the natural pressure from falling slag, subsequent cleaning actions can be achieved without an additional power source, which is both energy-saving and efficient, reducing the operating cost of the device. When the gear 1208 rotates under the drive of the rack 1205, it can stably transmit the meshing force to the rotating rod 1207.

[0036] In an optional embodiment, the striking structure includes a fixing ring 1209, a receiving frame 1210, and a striking hammer 1211. The fixing ring 1209 is sleeved on the rotating rod 1207, and the striking hammer 1211 is connected to the fixing ring 1209 through the receiving frame 1210. The striking hammer 1211 can swing and strike the first guard plate 1.

[0037] See also Figure 6 A retaining ring 1209 is fixedly installed on the outer surface of one end of the rotating rod 1207. A receiving frame 1210 is fixedly installed on the outer surface of the retaining ring 1209, and a striking hammer 1211 is fixedly installed at the bottom of the receiving frame 1210. The retaining ring 1209 firmly connects the receiving frame 1210 and the rotating rod 1207, so that the rotation of the rotating rod 1207 can accurately drive the movement of the receiving frame 1210 and the striking hammer 1211, ensuring that there is no deviation in the power transmission process and improving the accuracy and reliability of the device.

[0038] In an optional embodiment, a slide rail 9 is fixedly installed at the bottom of the first baffle plate 1, and a sliding door 10 is slidably connected to the slide rail 9. A beater 1211 is disposed above the slide rail 9. A drain pipe 8 is fixedly installed on the first baffle plate 1, and the drain pipe 8 is located above the sliding door 10.

[0039] See Figure 3 and Figure 7 A slide rail 9 is fixedly installed on the back of the first guard plate 1. A sliding door 10 is slidably connected to the outer surface of the slide rail 9. The front of the sliding door 10 is in contact with the back of the first guard plate 1. A pull frame 11 is fixedly installed on the back of the sliding door 10. A drain pipe 8 is fixedly installed inside the lower side of the first guard plate 1. The drain pipe 8 is located on the upper side of the sliding door 10.

[0040] The slide rail 9, fixedly installed on the back of the first baffle plate 1, is slidably connected to the sliding door 10, and the front of the sliding door 10 is flush with the back of the first baffle plate 1. This design allows the sliding door 10 to slide smoothly along the slide rail 9, facilitating the opening and closing of the sliding door 10 as needed. The drain pipe 8, fixedly installed inside the lower side of the first baffle plate 1, is located above the sliding door 10. During use, when water or liquid accumulates on the surface of the first baffle plate 1, it flows down the surface and is promptly discharged through the drain pipe 8, preventing water from affecting the sliding of the sliding door 10 and ensuring its normal opening and closing. This also ensures smooth drainage of the entire device, preventing water accumulation from corroding the device or affecting its normal operation. The sliding door 10 is normally closed to block slag and stones. The pull frame 11 is manually or mechanically pulled to open and remove slag, while the drain pipe 8 remains open for drainage.

[0041] In an optional embodiment, the synchronous cleaning component 14 includes a rectangular block 1401, a placement rack 1402, and a cleaning block 1403. The top end of the rectangular block 1401 is connected to the top plate 1201, and the bottom end is connected to the placement rack 1402. The cleaning block 1403 is installed on the placement rack 1402 and is disposed on the slide rail 9.

[0042] See Figure 7 The upper surface of rectangular block 1401 is fixedly installed to the lower surface of top plate 1201. The front of placement rack 1402 is fixedly installed to the lower back of rectangular block 1401. The upper surface of cleaning block 1403 is fixedly installed to the lower surface of placement rack 1402. The right side of connecting rack 1404 is fixedly installed to the left side of placement rack 1402. When top plate 1201 moves downward under pressure from falling debris, it will drive rectangular block 1401 and placement rack 1402 to move synchronously, thereby causing cleaning block 1403 to move accordingly. The cleaning action of cleaning block 1403 and the striking action of hammer 1211 work together to process slide rail 9.

[0043] In an optional embodiment, the first baffle plate 1 is fixedly installed with a first guide block 13 and a second guide block 15. The first guide block 13 is slidably connected to the rack 1205, and the second guide block 15 is slidably connected to the rectangular block 1401.

[0044] See Figure 4 A first guide block 13 is fixedly installed on the back of the first baffle plate 1, and the inner wall of the first guide block 13 is slidably connected to the rack 1205. When the slag-blocking and tapping assembly 12 is working, the rack 1205 moves up and down. The first guide block 13 provides precise guidance and limiting for the movement of the rack 1205, ensuring that the rack 1205 can only move in a straight line along the direction set by the first guide block 13. This prevents the rack 1205 from deviating or shaking during movement, thus ensuring that the slag-blocking and tapping assembly 12 can work stably and accurately, improving the reliability and stability of the slag-blocking and cleaning mechanism. A second guide block 15 is also fixedly installed on the back of the first baffle plate 1, and the outer surface of the rectangular block 1401 is slidably connected to the inner wall of the second guide block 15. The second guide block 15 provides precise guidance and limiting for the movement of the rectangular block 1401, ensuring that the rectangular block 1401 can only move in a straight line along the direction set by the second guide block 15.

[0045] It should also be noted that, see Figure 1 and Figure 2A second guard plate 2 can also be installed on the side of the first guard plate 1. Specifically, anchor rods 3 are fixedly installed on both sides of the first guard plate 1, and plug-in rods 4 are fixedly installed at the bottom of the anchor rods 3. A plug-in groove 5 is opened on the side of one anchor rod 3, and a plug-in block 6 is fixedly installed on the side of the other anchor rod 3. A fixing groove 7 is opened inside the plug-in block 6. In use, the first guard plate 1 and the second guard plate 2 are spliced ​​together. By inserting the plug-in blocks 6 set on the anchor rods 3 on both sides of the first guard plate 1 into the plug-in grooves 5 of the corresponding anchor rods 3 on the second guard plate 2, and then using the fixing groove 7 opened inside the plug-in block 6 in conjunction with the external fasteners, locking can be completed. At the same time, the plug-in rods 4 at the bottom of the anchor rods 3 are inserted into the foundation to complete the overall anchoring.

[0046] By setting up the synchronous cleaning component 14, the problem of blockage in the drain hole is addressed in a synchronized manner. The reciprocating motion of the cleaning block 1403 continuously taps or scrapes the inner opening of the drain pipe 8. Using the same slag impact power source, the tapping hammer 1211 is simultaneously driven to strike the slide rail 9 and the cleaning block 1403 cleans the slide rail 9. The cleaning action of the cleaning block 1403 on the slide rail 9 effectively removes the mud and fine soil accumulated on the surface of the filter layer, preventing the accumulation of water pressure behind the wall from causing the first baffle plate 1 or the second baffle plate 2 to overturn. The sliding door 10, together with the slide rail 9 and the pulling frame 11, achieves vertical upward sliding opening, occupying little external space and facilitating slag removal operations in narrow spaces. The entire device achieves rapid assembly through a modular splicing structure with the insertion slot 5, insertion block 6, and fixing slot 7. The anchor rod 3 and insertion rod 4 ensure reliable connection with the foundation, combining the advantages of rapid deployment, self-cleaning, and low maintenance costs.

[0047] The working principle of the protective device in this embodiment is explained below: When a slag runoff occurs on the slope, the falling slag first impacts the top plate 1201. The top plate 1201, subjected to the impact force, moves downwards, causing the fixing block 1202 to move downwards synchronously. The fixing block 1202 compresses the connecting spring 1203, which, through the telescopic rod 1204, pushes the rack 1205 to slide vertically downwards along the inner wall of the first guide block 13. As the rack 1205 moves downwards, it drives the gear 1208 to rotate, thus converting the linear impact pressure of the falling slag into the rotational meshing force of the gear 1208. The rotation of the gear 1208 causes the rotating rod 1207 to rotate synchronously, and the fixing ring 1209 rotates accordingly, causing the receiving frame 1210 to drive the striking hammer 1211 at its bottom to perform an arc-shaped oscillating motion. After the impact of the slag and stone is completed, the connecting spring 1203 returns to its original position and extends, causing the rack 1205 to return to its original position. The gear 1208 rotates in the opposite direction, and the striking hammer 1211 swings in the opposite direction to strike the outside of the slide rail 9. The vibration dislodges the slag stuck in the slide rail 9, preventing the sliding door 10 from getting stuck. While the slag-blocking and striking component 12 is working, the synchronous cleaning component 14 is driven synchronously. When the top plate 1201 moves up and down with the impact of the slag and stone, the rectangular block 1401 slides up and down synchronously along the inner wall of the second guide block 15. The reciprocating motion of the rectangular block 1401 drives the cleaning block 1403 to clean the slide rail 9 through the placement frame 1402, wiping off the mud and fine soil accumulated inside the drainage hole. After the slag behind the first baffle plate 1 reaches a certain height, the sliding door 10 is opened manually or mechanically by pulling the frame 11 to slide upward along the slide rail 9 and clean the accumulated slag and stone. After cleaning, the sliding door 10 is closed, restoring the blocking state.

[0048] It should also be noted that the first guard plate 1 and the second guard plate 2 should be made of high-strength wear-resistant steel or precast reinforced concrete, and their surfaces should be hot-dip galvanized or epoxy coated to resist the damp erosion and impact wear of slag in the slope environment. The rack 1205 and gear 1208, as core transmission components, are made of 40Cr or 42CrMo alloy steel and have undergone tempering and surface quenching treatment. The tooth surfaces should be regularly lubricated with grease to prevent premature wear due to dry friction. The connecting spring 1203 should be a fatigue-resistant stainless steel spring and be rust-proofed to avoid fatigue fracture due to repeated compression and impact. The contact surface between the sliding door 10 and the slide rail 9 should be inlaid with wear-resistant copper strips or high-polymer self-lubricating pads to reduce sliding friction resistance. The drain pipe 8 is made of UPVC or HDPE material, with a smooth inner wall that is not prone to mud accumulation and is corrosion-resistant. The ends of the beater 1211 and the cleaning block 1403 should be covered with polyurethane rubber pads to buffer impact, reduce noise, and prevent hard damage to the slide rail 9 and the drain pipe 8 opening. All fasteners must be treated with stainless steel or Dacromet coating to prevent them from becoming unusable after rusting.

[0049] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them; although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features; and these modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
