Description

Technical Field

[0001] The utility model relates to the field of environmental protection facilities, in particular to a windproof device for covering the slope of a filler heap in a fly ash landfill site. Background Art

[0002] As an effective means of waste reduction and resource recycling, waste incineration power generation has broad application prospects. However, as a hazardous waste, incineration fly ash must be stabilized and then landfilled in accordance with the provisions of the "Pollution Control Standard for Domestic Waste Landfill Sites" (GB 16889-2008). In subsequent daily management, the waterproof membrane covering the landfill to prevent fly ash from being leached by rainwater is often blown away, rolled up, or damaged by the wind, which may cause 12 metal pollutants such as mercury, copper, zinc, lead, and cadmium in the fly ash to pollute the surrounding and groundwater environments along with rainwater.

[0003] Facing this problem, landfills often choose to use waste tires and sandbags to stabilize the waterproof membrane. However, in the face of frequent strong winds, this method is not timely and effective, time-consuming and laborious, and its effect is not ideal. After strong winds, there are always exposed fly ash chelates blown open. To solve this problem, the utility model proposes a device applicable to fly ash landfills, which is convenient to use, utilizes wind power and gravity, and can better face sudden extreme weather, enabling the proper handling of the last pain point of waste incineration sites. At present, although there are some windproof measures to deal with this situation, they have poor mobility, cannot be applied to repeated operations in the same area, and are only applicable to flat areas, unable to handle the windproofing of slopes, which is precisely the key point and difficulty of windproofing work. How to stably cover the waterproof membrane on the slope and complete this work conveniently, effectively, and time-saving and labor-saving is the key problem to be solved by the utility model. The structure of the utility model is simple, easy to manufacture, and low in cost, but the structure is flexible and easy to rotate, and can be applicable to covers of various slopes. It provides a feasible solution for solving the windproof problem of landfills.

[0004] It should be noted that the information disclosed in the above background art section is only used for understanding the background of the present application, and thus may include information that does not constitute the prior art known to those of ordinary skill in the art. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a windproof operation by combining multiple methods such as wind power, elastic force, and gravity, thereby making the use process simple and easy, reducing the occurrence of slope falling events, and increasing safety.

[0006] To achieve the above purpose, the utility model provides the following technical solutions:

[0007] A wind-proof device for covering the slope of a filler heap in a fly ash landfill, characterized in that it includes a hand pull rod, a stabilizing rope, a water pipe, a telescopic rod, a stabilizing pull rod, a rope-passing spring buckle, a support barrel, a first covering barrel, a second covering barrel, and a fixing barrel; the hand pull rod is connected to the middle of the support barrel through a wheel shaft; the telescopic rod is used for connecting the support barrel and the covering barrel, plays a supporting role, can be telescoped through a buckle, and is sleeved outside the water pipe; the water pipe is connected by a corrugated pipe and a flexible water pipe, and water flows inside; the stabilizing pull rod is connected to the upper part of the second covering barrel and is connected to the fixing barrel through a rope, so as to determine the directions of the first covering barrel and the second covering barrel and prevent them from tilting; the rope-passing spring buckle includes a spring, a button, and a housing, mainly controls the length of the rope and makes the rope taut; the support barrel is connected to a support rod, a telescopic rod, and a water pipe, is located at the bottom, supports the first covering barrel and the second covering barrel, has a water inlet on its side, and has an anti-slip rubber pad at the bottom; the anti-slip rubber pad has a hard plastic plate on the upper part and a rubber pad on the lower part, and is used for connecting the hinge with the support barrel, the first covering barrel, the second covering barrel, and the fixing barrel.

[0008] The hand pull rod includes a pull ring, a pull rod, and a triangular support column; preferably, the bottom of the pull ring is made of rubber, which has an anti-slip and supporting effect; the telescopic rod is divided into upper and lower sections, and the radius of the upper half section is slightly larger, so as to sleeve the lower half section. There is a buckle in the middle, which is an inward-pressing buckle. The position is fixed by the spring pressure inside. Preferably, the buckle is solid, and the telescopic rod is made of aluminum alloy, which is light in weight and high in strength; the telescopic rod is a hollow cylinder, with a diameter of 6.0 cm and a thickness of 2.0 - 3.0 mm. There is a circular hole with a diameter of 5.0 cm on the upper bottom surface of the upper half section and the lower bottom surface of the lower half section respectively. The circular holes on the upper bottom surface of the upper half section and the lower bottom surface of the lower half section are such that the centers of the circular holes coincide with the centers of the upper and lower bottom surfaces. The remaining parts of the upper bottom surface of the upper half section and the lower bottom surface of the lower half section are enclosures. When the length of the telescopic rod is shortened, the enclosures are used to compress the corrugated pipe 302 in the water pipe to control the length of the water pipe.

[0009] Both ends of the telescopic rod are provided with triangular support columns. The triangular support columns are composed of two prisms. Preferably, the two prisms form a 90° angle, and the lengths of the prisms are the same, 20 - 25 cm. One side is connected to the telescopic rod, and the other side is connected to the support barrel or the first covering barrel and the second covering barrel. And the position of the connection point is at half of the height of the support barrel. In this way, when the support barrel plays a supporting role, the included angle between the triangular support column and the ground is larger, and the friction force received by the support barrel in the horizontal direction is smaller. At the half to two-thirds of the height of the first covering barrel, the included angle between the bottom plane of the covering barrel and the ground becomes smaller, and it fits more closely with the fly ash covering film, with a greater friction force, and it also avoids the first covering barrel from tipping over; the central lines of the included angles of the two prisms are respectively on the half-surfaces of the sides of the support barrel, the first covering barrel, and the second covering barrel, and the prisms are triangular, so the connection is more stable.

[0010] The water pipe is composed of two parts: a bellows and a plastic hose. The bellows is located inside the telescopic rod, and the outermost diameter of the bellows 302 is 5.2 to 5.4 cm. When the telescopic rod is stretched, the bellows 302 is deformed and stretched. When the telescopic rod is shortened, the bellows is squeezed by the enclosure of the telescopic rod and folded and shortened. The plastic hose connects the bellows and the inside of the bucket. A soft material is used, and the water pipe connects the inside of the support bucket, the No. 1 covering bucket, and the No. 2 covering bucket.

[0011] The rope threading spring buckle includes a buckle body, a spring, and a sliding cavity; the buckle body and the sliding cavity have circular holes with the same diameter. When the buckle body is pressed, the spring in the sliding cavity is deformed, so that the circular holes of the buckle body and the sliding cavity are aligned, thereby adjusting the length of the stable rope and entering a locked state when released.

[0012] The support barrel includes a water inlet and outlet, a support column connecting component, a water bucket, a non-slip rubber pad, and a wind wheel; the water inlet and outlet are located at the lower part of the circular surface of the water bucket and have a valve; the support column connecting component is made of steel castings and is connected to the middle of the water bucket, and there is an axle at the connection. The support column connecting component on one side is used to adjust the tilt direction of the No. 1 covering bucket and the No. 2 covering bucket, and the support column connecting component on the other side is used to adjust the direction of the hand pull rod; preferably, the water bucket of the support barrel is made of polyolefin, which is light, hard, UV-resistant, and cost-effective. The non-slip rubber pad is located at the bottom of the bucket and is composed of a hard plastic plate and a suction cup rubber pad. The hard plastic is glued to the bottom of the bucket with glue, and the hard plastic is glued to the suction cup rubber pad with glue. The length and width of the bottom of the bucket are consistent with the length and width of the non-slip rubber pad, and the four corners of the bucket are rounded. There is a hemispherical suction cup in the middle area of the suction cup rubber pad, which is a regular hemispherical hole. Preferably, the hemispherical suction cup is in the middle of the non-slip rubber pad, and there is no hemispherical suction cup near the long side. The wind unloading wheel is located at the central axis of the semicircular cross-section of the bucket.

[0013] The described No. 1 covering barrel is located between the supporting barrel and the No. 2 covering barrel. Its lower part is connected to the supporting barrel through a water pipe, and its upper part is connected to the No. 2 covering barrel through a water pipe. The No. 1 covering barrel is composed of a water bucket, a support column connecting component, a hinge, a spring buffer, an anti-slip rubber pad, and a wind discharge wheel. Preferably, the radius of the right half circle of the water bucket is smaller than that of the left half circle. Preferably, the support column connecting component is made of steel castings and is used to connect the telescopic rod and the water bucket, with one used at the upper and lower parts respectively. The hinge has its two sides connected to the water bucket and the anti-slip rubber pad respectively, enabling the water bucket and the anti-slip rubber pad to be rotatably connected. The spring buffers are located at the lower two corners between the water bucket and the anti-slip rubber pad. Each spring buffer includes a spring extrusion column, a spring, and a spring body cavity. The spring extrusion column is fixed at the bottom of the covering barrel. One end of the spring is fixed at the connection between the spring body cavity and the anti-slip rubber pad, and the cavity is aligned with the extrusion column. When the spring is compressed, the two coincide. When the instantaneous wind force is large and blows up the film covering, the spring buffer uses its elastic force to slow down the wind force, making the covering stable and able to withstand greater wind blowing.

[0014] The described wind discharge wheel is used to convert wind energy into kinetic energy. The No. 2 covering barrel is located above the No. 1 covering barrel and is composed of a water bucket, a support column connecting component, a hinge, a spring buffer, an anti-slip rubber pad, a wind discharge wheel, and an exhaust valve. There are two support column connecting components in total, which are all rotatably connected using a wheel axle and can freely rotate in direction to cope with slope changes, adjust the load-bearing direction of the water bucket, and better fit the film covering. The lower support column connecting component connects the telescopic rod and the water bucket, and the upper support column connecting component is connected to the stabilizing rod.

[0015] The described fixed barrel is composed of a water inlet and outlet, a water bucket, a support column connecting component, a hinge, a spring buffer, an anti-slip rubber pad, a wind discharge wheel, and an exhaust valve. It is located above the No. 2 covering barrel and is placed on the upper platform of the slope. It is used to fix the No. 1 covering barrel and the No. 2 covering barrel to prevent them from shaking and overturning. At the same time, relying on its own gravity, it presses the film covering above the slope.

[0016] The working process of the wind prevention device for the fly ash landfill site in the preferred embodiment of the present utility model is as follows:

[0017] Face the side of the wind-breaking device with the air-release wheel towards the ground, which includes a support barrel, a first covering barrel, a second covering barrel, and a fixed barrel. Pull the hand lever and the pull ring of the fixed barrel respectively. Since the fixing part of the support barrel and the fixed barrel has a wheel axle, the height of the hand lever can be adjusted freely. Move the wind-breaking device to the upper platform position of the slope. Then pass one end of the stabilizing rope through the pull ring and tie it tightly, and pass the other end through the rope-passing spring buckle, and then tie the other end to the stabilizing lever of the fixed barrel. Adjust the rope-passing spring buckle so that the stabilizing rope is at the maximum rope length. According to the height of the slope, initially adjust the lengths of the telescopic rods between the first covering barrel, the second covering barrel, and the support barrel so that the slope wind-breaking device can better cover the plastic film. Slowly lower the first covering barrel, the second covering barrel, and the support barrel from above on the upper platform of the slope so that the side with the anti-slip rubber pad faces the plastic film. Then, according to the actual covering situation, lift the first covering barrel, the second covering barrel, and the support barrel, and adjust the lengths of the telescopic rods to appropriate positions. The lengths of the two telescopic rods are roughly the same, and the second covering barrel is at two-thirds to three-fourths of the slope height.

[0018] After adjusting the lengths of the telescopic rods, adjust the positions of the first covering barrel, the second covering barrel, the support barrel, and the fixed barrel so that each barrel is close to the plastic film. The first covering barrel and the second covering barrel are not skewed. Adjust the position of the fixed barrel so that it is 1 m to 1.5 m away from the slope edge. At this time, the stabilizing rope has sufficient tension, and there is a certain distance between the fixed barrel and the edge. When the first covering barrel and the second covering barrel are skewed, or when the plastic film is affected by strong wind, it can provide a relatively large buffer distance. Press the rope-passing spring buckle so that the stabilizing rope keeps the pull ring of the stabilizing lever in a taut state. Open the water inlets and outlets of the support barrel and the fixed barrel respectively, and fill water into the barrels. When water overflows from the exhaust valve, stop filling water and close the inlets and outlets. At this time, the ball valve of the exhaust valve will block the outlet of the exhaust valve. Press the rope-passing spring buckle again so that the stabilizing rope is in a taut state.

[0019] When further construction is needed on the slope, untie the stabilizing rope on the stabilizing lever of the fixed barrel, open the valve of the water inlet and outlet of the support barrel. After the water in the second covering barrel is emptied, you can pull the pull ring of the hand lever and move it to the required position.

[0020] Compared with the prior art, the beneficial effects of the present utility model are:

[0021] Through its unique hollow structure, the overall weight is greatly reduced, making the operation more convenient and easier in actual application, and significantly saving the labor input.

[0022] The process is extremely simple, without complex operation steps and professional skills, greatly reducing the operation difficulty, effectively reducing the occurrence of accidental events such as slope falls that may be caused by improper operation or complex processes, thus significantly enhancing the safety during the construction process.

[0023] The wind force, elastic force, and gravitational force are ingeniously combined and act together on the windproof operation. When the wind force comes, the wind unloading wheel in the device can convert part of the wind energy into kinetic energy, reducing the direct impact of the wind force on the plastic film; the spring buffer can effectively slow down the action of the instantaneous strong wind by using the elastic force, ensuring the stability of the plastic film; and each water-filled barrel relies on gravity to firmly press the plastic film, enhancing the windproof effect. This makes the windproof operation more stable and reliable, providing protection for the plastic film on the slopes of the fly ash landfill site. Brief Description of the Drawings

There is a circular hole with a diameter of 5.0 cm on the upper bottom surface of the upper half section and the lower bottom surface of the lower half section respectively. The circular holes on the upper bottom surface of the upper half section and the lower bottom surface of the lower half section each have a circular hole, and the centers of the circular holes coincide with the centers of the upper and lower bottom surfaces.

The hard plastic is adhered to the bottom of the water bucket with glue, and the hard plastic is adhered to the suction cup rubber pad 7042 with glue. The length and width of the bottom of the water bucket are the same as those of the anti-slip rubber pad 704, and the four corners of the water bucket are rounded; there are hemispherical suction cups in the middle area of the suction cup rubber pad 7042, which are regular hemispherical holes; preferably, the hemispherical suction cups are in the middle of the anti-slip rubber pad 704, and there are no hemispherical suction cups near the long side; the wind unloading wheel is located at the central axis of the semi-circular cross-section of the water bucket.

At the same time, relying on its own gravity, it presses the plastic film above the slope.

[0060] In the preferred embodiment of the present utility model, the working process of the wind prevention device for the fly ash landfill is as follows:

[0061] Face the side with the wind discharge wheel of the wind prevention device towards the ground, including the support barrel 7, the first covering barrel 8, the second covering barrel 9, and the fixed barrel 10. Pull the hand lever 1 and the pull ring of the fixed barrel 10 respectively. Since the fixing parts of the support barrel 7 and the fixed barrel 10 have a wheel axle, the height of the hand lever that can be pulled can be freely adjusted. Move the wind prevention device to the upper platform position of the slope. Then pass one end of the stabilizing rope 2 through the pull ring 5 and tie it tightly, and pass the other end through the rope-passing spring buckle 6, and then tie the other end to the stabilizing pull rod 5 of the fixed barrel 10. Adjust the rope-passing spring buckle 6 so that the stabilizing rope 2 is at the maximum rope length. According to the height of the slope, initially adjust the length of the telescopic rods 4 between the first covering barrel 8, the second covering barrel 9, and the support barrel 7, so that the slope wind prevention device can better cover the plastic film. Slowly lower the first covering barrel 8, the second covering barrel 9, and the support barrel 7 from above on the upper platform of the slope, so that the side of the anti-slip rubber pad 704 faces the plastic film. Then, according to the actual covering situation, lift the first covering barrel 8, the second covering barrel 9, and the support barrel 7, and adjust the length of the telescopic rods 4 to a suitable position. The lengths of the two telescopic rods 4 are roughly the same, and the second covering barrel 9 is at two-thirds to three-fourths of the slope height.

[0062] After adjusting the length of the telescopic rods 4, adjust the positions of the first covering barrel 8, the second covering barrel 9, the support barrel 7, and the fixed barrel 10 so that each barrel is close to the plastic film. The first covering barrel 8 and the second covering barrel 9 are not skewed. Adjust the position of the fixed barrel 10 so that it is 1 m to 1.5 m away from the slope edge. At this time, the stabilizing rope 2 has sufficient tension, and there is a certain distance between the fixed barrel 10 and the edge. When the first covering barrel 8 and the second covering barrel 9 are skewed or the plastic film is affected by strong wind, it can provide more buffer distance. Press the rope-passing spring buckle 6 so that the stabilizing rope 2 makes the pull ring of the stabilizing pull rod 5 in a tight state. Open the water inlets and outlets of the support barrel 7 and the fixed barrel 10 respectively to inject water into the barrels. When water overflows from the exhaust valve 1007, stop injecting water and close the water inlets and outlets. At this time, the ball valve of the exhaust valve 1007 will block the outlet of the exhaust valve 1007. Press the rope-passing spring buckle 6 again so that the stabilizing rope 2 is in a tight state.

[0063] When further construction is required on the slope, the stabilizing rope 2 on the stabilizing pull rod 5 of the fixed barrel 10 is untied, and the inlet and outlet valves of the support barrel 7 are opened. After the water in the second covering barrel 9 is emptied, the pull ring of the hand pull rod 1 can be grasped and the device can be moved to the required position.
