Description

Technical Field

[0001] This invention relates to the field of sand control and stabilization technology, and more specifically, to a wind-dissipating and energy-consuming transmission-type sand-blocking complex. Background Technology

[0002] Wind and sandstorms are a significant factor severely restricting economic and social development in arid Northwest my country. Wind is the driving force behind sand movement, so preventing and controlling wind and sandstorms must begin with wind control. The purpose of wind and sandstorm control projects is to reduce wind speed, alter the transport capacity of airflow, and block the movement of windblown and shifting sand, thereby protecting railways, highways, farmland, and towns from wind and sand damage.

[0003] Sand-blocking fences are one of the most important measures in wind and sand control projects. Traditional sand-blocking fences are mainly high-standing sand barriers, made of nylon netting, shrub branches, reeds, etc., and their shape is mainly a linear fence perpendicular to the prevailing wind direction.

[0004] Long-term practical application has revealed the following problems with existing sand-blocking fences: 1. Because the sand-blocking fences are arranged linearly, they only have the function of blocking sand, but not the function of transporting and guiding sand. When the pressure of wind and sand on the sand-blocking fences is too great, the fences are easily damaged; 2. After a certain amount of sand and dust accumulates at the fence, subsequent wind and sand can easily cross the fence, causing the current fences to fail. Summary of the Invention

[0005] This invention discloses a wind-dissipating and energy-consuming transmission-type sand-blocking complex to improve the above-mentioned problems.

[0006] The technical solution adopted by the present invention to solve the above-mentioned technical problems is as follows:

[0007] To achieve the above objectives, this invention discloses a wind-dissipating and energy-consuming transmission-type sand-blocking complex, comprising:

[0008] Multiple sand control units are arranged at intervals, with gaps between adjacent sand control units. Each sand control unit includes a support column, a sand control net, and multiple fixed columns. The multiple fixed columns are respectively arranged on both sides of the support column, and the multiple fixed columns and the support column are arranged in a triangle. The sand control net is connected to the support column and the multiple fixed columns respectively.

[0009] A sand-transporting device includes a conveying component and multiple power components. The power components are arranged one-to-one with multiple gaps. Each power component includes a spiral fan, a rotating shaft, and a transmission structure. The spiral fan is connected to the rotating shaft and is located at one of the gaps. The rotating shaft is connected to the conveying component via the transmission structure. When the spiral fan rotates, it drives the rotating shaft to rotate, thereby driving the transmission structure to operate.

[0010] A sand collection box is located at the output end of the transmission structure.

[0011] Optionally, the power assembly further includes a housing and a sand-blocking net. The housing includes an air inlet, a sand-collecting chamber, an air outlet, and a sand-discharge outlet. The air inlet, the air outlet, and the sand-discharge outlet are all connected to the sand-collecting chamber, and the air inlet and the air outlet are arranged opposite to each other. The rotating shaft is rotatably connected to the housing. The spiral fan is located inside the sand-collecting chamber and is arranged facing the air inlet. The sand-blocking net is located between the air outlet and the sand-collecting chamber, and the sand-discharge outlet is arranged facing the conveying assembly.

The two first elastic members are arranged one-to-one with the two wind deflectors. The two ends of the first elastic members are rotatably connected to the housing and the wind deflectors respectively. The first elastic members cause the wind deflectors to have a tendency to rotate toward one of the wind deflectors. When the wind deflector rotates toward the other wind deflector, the air inlet narrows.

[0013] Optionally: the conveying assembly is provided with a rack;

[0014] The transmission structure includes a first gear, a second gear, a third gear, a first transmission shaft, a second transmission shaft, a first rotating assembly, a second rotating assembly, and a belt.

[0015] Optionally: the first rotating assembly includes a first fixed wheel, a first sliding wheel, and a second elastic member. The first fixed wheel is fixedly mounted on the first drive shaft. The first sliding wheel is coaxially arranged with the first fixed wheel and is slidably connected to the first drive shaft. The two ends of the second elastic member are respectively connected to the first sliding wheel and the first drive shaft. The second elastic member causes the first sliding wheel to tend to move closer to the first fixed wheel.

[0016] The second rotating assembly includes a second fixed wheel, a second sliding wheel, and a third elastic element. The second fixed wheel is rotatably connected to the second transmission shaft. The second sliding wheel is coaxially arranged with the second fixed wheel and is slidably connected to the second transmission shaft. The third elastic element causes the second sliding wheel to tend to move away from the second fixed wheel.

[0017] The belt has a trapezoidal cross-section, with a portion of the belt abutting between the first fixed pulley and the first sliding pulley, and another portion of the belt abutting between the second fixed pulley and the second sliding pulley.

[0018] Optionally, the transmission structure further includes a control rod, a connecting rod, and a rotating block. The control rod abuts against one of the wind deflectors. The third elastic element is connected to the control rod, and the third elastic element causes the control rod to have a tendency to push the wind deflector to rotate toward the other wind deflector. The rotating block is connected to the second sliding wheel and is rotatably connected to the connecting rod. The end of the connecting rod away from the second sliding wheel abuts against the control rod. The side of the control rod facing the connecting rod is provided with an inclined surface, so that when the control rod pushes the wind deflector to rotate toward the other wind deflector, the connecting rod pulls the second sliding wheel to move away from the second fixed wheel.

[0019] Optionally: the diameter of the first fixed wheel gradually decreases in the direction toward the first sliding wheel, and the diameter of the first sliding wheel gradually decreases in the direction toward the first fixed wheel; the diameter of the second fixed wheel gradually decreases in the direction toward the second sliding wheel, and the diameter of the second sliding wheel gradually decreases in the direction toward the second fixed wheel.

[0023] Compared with the prior art, the beneficial effects achieved by the present invention are:

[0024] The wind-dissipating and energy-consuming transmission-type sand-blocking complex disclosed in this invention guides sand and dust through a sand-prevention unit. The sand-prevention net, while guiding the sand, also has the effect of collecting sand and wind, thereby increasing the flow velocity of sand and dust in the gaps. On one hand, the power component can be used to convert wind power, causing the wind at a certain speed to drive the spiral fan to rotate, which in turn drives the conveying component. On the other hand, when the sand and dust pass through the power component, they will be deposited on the conveying component and transported to the sand collection box along with it.

[0025] This wind-dissipating and energy-consuming transmission-type sand-blocking complex features a triangular arrangement of supports and fixed columns. After the sand-blocking net is connected to the supports and fixed columns, its shape forms a triangular zigzag pattern, providing strong stability. Simultaneously, the convex side of the sand-blocking net is designed as the windward side, guiding windblown sand and effectively reducing the pressure on the net. When windblown sand blows onto the net, the net guides it, preventing sand and dust from accumulating on the windward side. Furthermore, the conveying components promptly remove this sand and dust, preventing the sand-blocking unit from malfunctioning due to excessive sand and dust accumulation in front of the net.

[0044] Example:

[0045] See Figure 1 This invention discloses a wind-dissipating and energy-consuming transmission-type sand-blocking complex, comprising a sand-transporting device 200, a sand-collecting box 300, and multiple sand-prevention units 100. Each sand-prevention unit 100 includes a support column 110, a sand-prevention net 130, and multiple fixed columns 120. These fixed columns 120 are located on both sides of the support column 110, forming a triangle with the support column 110. The sand-prevention net 130 is connected to both the support column 110 and the fixed columns 120, resulting in a zigzag shape. The multiple sand-prevention nets 130 are spaced apart, with gaps between adjacent nets. The sand-transporting device 200 includes a conveying component 210 and multiple power components 220. The power components 220 and the multiple gaps are arranged in a one-to-one correspondence, and the output end of the power component 220 is connected to the conveying component 210. The conveying component 210 is disposed on the concave surface of the sand-prevention net 130. In the desert, when the wind blows, the wind and sand are guided by the sand-proof net 130 through the gaps and blown toward the power component 220. After absorbing the wind, the power component 220 converts it into the power to drive the transmission component 210. After encountering the power component 220, the sand settles on the transmission component 210 and is transported to the sand collection box 300 for storage.

[0046] The wind-dissipating and energy-consuming transmission-type sand-blocking complex disclosed in this embodiment guides sand and dust through the sand-blocking unit 100. The sand-blocking net 130, while guiding the sand and dust, also has the effect of collecting sand and wind, thereby increasing the flow velocity of sand and dust in the gaps. On the one hand, the power component 220 can be used to convert wind power, so that the wind with a certain speed blows the spiral fan 221 to rotate, thereby driving the conveying component 210 to work. On the other hand, when the sand and dust pass through the power component 220, the sand and dust will be deposited on the conveying component 210 and conveyed to the sand collection box 300 along with the conveying component 210.

[0047] The support columns 110 and fixed columns 120 of this wind-dissipating and energy-consuming transmission-type sand-blocking complex are arranged in a triangular pattern. After the sand-blocking net 130 is connected to the support columns 110 and fixed columns 120, its shape is a triangular zigzag shape, which has strong stability. At the same time, the convex side of the sand-blocking net 130 is set as the windward side, which guides the sand and effectively reduces the pressure on the sand-blocking net 130. When sand blows onto the sand-blocking net 130, the sand-blocking net 130 guides the sand and prevents the sand and dust from accumulating on the windward side of the sand-blocking net 130. Moreover, this sand and dust can be promptly transported away by the conveying component 210, thereby preventing the sand-blocking unit 100 from failing due to excessive sand and dust accumulation in front of the sand-blocking net 130.

[0048] See Figure 1 Multiple sand control units 100 are spaced apart, with gaps between adjacent sand control units 100. Each sand control unit 100 includes a support column 110, a sand control net 130, and multiple fixed columns 120. The multiple fixed columns 120 are respectively arranged on both sides of the support column 110, and the multiple fixed columns 120 and the support column 110 are arranged in a triangle. The sand control net 130 is connected to the support column 110 and the multiple fixed columns 120 respectively.

[0049] See Figure 2 The sand transport device 200 includes a conveying component 210 and multiple power components 220. Each power component 220 is correspondingly installed at one of the gaps, meaning one power component 220 is installed at each gap. Simultaneously, all power components 220 are connected to the conveying component 210, and the conveying component 210 is driven by all the power components 220. After the wind-dissipating and energy-consuming transmission-type sand-blocking complex is installed, the wind force experienced at different locations may not be the same, and the wind force is dynamically changing. A single power component 220 cannot guarantee the continuous operation of the conveying component 210. With multiple power components 220 connected to the conveying component 210, the conveying component 210 is driven by all the power components 220, reducing the burden on a single power component 220 and making the operation of the conveying component 210 easier and more flexible.

[0050] See Figure 4Each power assembly 220 includes a housing 224, a sand-blocking net 225, a spiral fan 221, a rotating shaft 222, a transmission structure 223, two first elastic elements, and two wind deflectors 226.

[0051] See Figure 5 The housing 224 includes an air inlet 2242, a sand collection chamber 2241, an air outlet 2243, and a sand outlet 2244. The air inlet 2242, air outlet 2243, and sand outlet 2244 are all connected to the sand collection chamber 2241, and the air inlet 2242 and air outlet 2243 are arranged opposite to each other. A rotating shaft 222 is rotatably connected to the housing 224. A spiral fan 221 is located inside the sand collection chamber 2241 and is connected to the rotating shaft 222.

[0052] A spiral fan 221 is located at the gap and faces the air inlet 2242. When air flows along the gap, it blows directly onto the spiral fan 221, causing it to rotate. The rotating shaft 222 is connected to the conveying assembly 210 via a transmission structure 223. When the spiral fan 221 rotates, it drives the rotating shaft 222, which in turn drives the transmission structure 223. A sand-blocking net 225 is located between the air outlet 2243 and the sand collection chamber 2241, with the sand outlet 2244 facing the conveying assembly 210. When sand enters the housing 224 along the gap and the air inlet 2242, it is first blocked by the spiral fan 221. As the sand blows and rotates the spiral fan 221, its speed decreases significantly, and some sand falls downwards under gravity, landing on the conveying assembly 210 through the sand outlet 2244. As the sandstorm continues to move forward with reduced speed and sand content, it is blocked by the sand-blocking net 225. At this time, all the sand and dust are blocked and fall onto the transmission component along the sand outlet 2244.

[0053] Both wind deflectors 226 are rotatably connected to the housing 224. The two wind deflectors 226 are positioned opposite each other, located on either side of the air inlet 2242. Two first elastic members are correspondingly arranged with the two wind deflectors 226. The two ends of each first elastic member are rotatably connected to the housing 224 and the wind deflector, respectively. The first elastic members cause the wind deflectors 226 to tend to rotate towards the other wind deflector 226. When the wind deflector 226 rotates towards the other wind deflector 226, the air inlet 2242 narrows. Under the elastic force of the first elastic members, the wind deflectors 226 are tilted. When wind and sand flow through the air inlet 2242, the wind deflectors 226 create a wind-gathering effect, thereby enhancing the power generated by the wind on the spiral fan 221. When the wind and sand are relatively calm, the wind deflectors 226 move closer together under the elastic force of the first elastic element, causing the air inlet 2242 to shrink. When the wind and sand speed increases, the wind pressure exerts pressure on the wind deflectors 226 as they flow through the air inlet 2242. At this time, the wind deflectors 226 will overcome the elastic force of the first elastic element and rotate in the direction away from the other wind deflector 226 under the action of wind pressure, causing the air inlet 2242 to enlarge. Enlarging the air inlet 2242 can, on the one hand, enhance the flow of wind and sand and prevent wind and sand from accumulating in the gaps; on the other hand, enlarging the air inlet 2242 can reduce the speed of wind and sand per unit area, thereby reducing the load on the propeller fan 221 and preventing the propeller fan 221 from rotating under load due to excessive wind speed.

[0054] Among them, see Figure 3 The conveying assembly 210 includes a rack 213, a conveyor belt 212, and two support rollers 211. The two support rollers 211 are spaced apart, and the conveyor belt is wound between the two support rollers 211. The rack 213 is mounted on the conveyor belt, and multiple gears are located between the two support rollers 211, and all of the multiple gears mesh with the rack 213.

[0055] See Figure 6The transmission structure 223 includes a first gear 2231, a second gear 2232, a third gear 2233, a first transmission shaft 2234, a second transmission shaft 2235, a first rotating assembly 2236, a second rotating assembly 2237, and a belt 2238. Both the first transmission shaft 2234 and the second transmission shaft 2235 are rotatably connected to the housing 224, and these three shafts (2234, 2235, and rotating shaft 222) are arranged in parallel, all facing from the air inlet 2242 towards the air outlet 2243. The first gear 2231 is mounted on the rotating shaft 222, and the second gear 2232 is mounted on the first transmission shaft 2234, meshing with the first gear 2231. The first rotating assembly 2236 is mounted on the first transmission shaft 2234, the second rotating assembly 2237 is mounted on the second transmission shaft 2235, and the belt 2238 is wound between the first rotating assembly 2236 and the second rotating assembly 2237. The third gear 2233 is mounted on the second drive shaft 2235, and the third gear 2233 meshes with the rack 213.

[0056] The first rotating assembly 2236, the second rotating assembly 2237, and the belt 2238 are configured to control the transmission ratio of the first drive shaft 2234 and the second drive shaft 2235, so as to ensure that when the rotational speed of the first drive shaft 2234 changes, the second drive shaft 2235 can also maintain a relatively stable rotational speed and continue to rotate.

[0057] Specifically, see Figure 7 and Figure 8The first rotating assembly 2236 includes a first fixed wheel 22361, a first sliding wheel 22362, and a second elastic element. The first fixed wheel 22361 is fixedly mounted on the first drive shaft 2234, and the first sliding wheel 22362 is coaxially arranged with the first fixed wheel 22361 and slidably connected to the first drive shaft 2234. The two ends of the second elastic element are respectively connected to the first sliding wheel 22362 and the first drive shaft 2234, and the second elastic element causes the first sliding wheel 22362 to tend to move closer to the first fixed wheel 22361. The second rotating assembly 2237 includes a second fixed wheel 22371, a second sliding wheel 22372, and a third elastic element. The second fixed wheel 22371 is rotatably connected to the second drive shaft 2235, and the second sliding wheel 22372 is coaxially arranged with the second fixed wheel and slidably connected to the second drive shaft 2235. The third elastic element causes the second sliding wheel 22372 to tend to move away from the second fixed wheel 22371. The diameter of the first fixed wheel 22361 gradually decreases in the direction toward the first sliding wheel 22362, and the diameter of the first sliding wheel 22362 gradually decreases in the direction toward the first fixed wheel 22361. The diameter of the second fixed wheel 22371 gradually decreases in the direction toward the second sliding wheel 22372, and the diameter of the second sliding wheel 22372 gradually decreases in the direction toward the second fixed wheel 22371. The belt 2238 has a trapezoidal cross-section, with a portion of the belt 2238 abutting between the first fixed wheel 22361 and the first sliding wheel 22362, and another portion of the belt 2238 abutting between the second fixed wheel 22371 and the second sliding wheel 22372.

[0058] The transmission structure 223 also includes a control rod 22391, a connecting rod 22392, and a rotating block 22394. The control rod 22391 abuts against one of the wind deflectors 226, and a third elastic element is connected to the control rod 22391, giving the control rod 22391 a tendency to push the wind deflector 226 towards the other wind deflector 226. The rotating block 22394 is connected to the second sliding wheel 22372, and is rotatably connected to the connecting rod 22392. One end of the connecting rod 22392 away from the second sliding wheel 22372 abuts against the control rod 22391. The control rod 22391 has an inclined surface on the side facing the connecting rod 22392, so that when the control rod 22391 pulls the wind deflector 226 towards the other wind deflector 226, the connecting rod 22392 pushes the second sliding wheel 22372 to move away from the second fixed wheel 22371.

[0059] The control lever 22391 is provided with a sliding groove, which is arranged along the length of the control lever 22391 and located on the side of the control lever 22391 facing the connecting rod 22392. The end of the connecting rod 22392 facing the control lever 22391 is provided with a locking block for engaging with the sliding groove; the locking block slides in contact with the sliding groove. (See reference...) Figure 4 When the control rod 22391 moves downward against the elastic force of the third elastic element, the inclined surface on the control rod 22391 pushes the connecting rod 22392 and the second sliding wheel 22372 closer to the second fixed wheel 22371. When the control rod 22391 moves upward under the elastic force of the third elastic element, the control rod 22391 pulls the connecting rod 22392 and the second sliding wheel 22372 away from the second fixed wheel 22371 by utilizing the cooperating force between the locking block and the locking groove. In this embodiment, in order to ensure the stable cooperation between the control rod 22391 and the connecting rod 22392, and to ensure that the control rod 22391 can stably pull the connecting rod 22392 when it moves upward, the slide groove can be set to a T-shaped groove or an inverted trapezoidal groove, etc.

[0060] The connecting rod 22392 is provided with a through hole 22393, and the second drive shaft 2235 extends into the through hole 22393. The second drive shaft 2235 is slidably engaged with the through hole 22393, and the second drive shaft 2235 can rotate relative to the connecting rod 22392 along its axis.

[0061] The working principle of the first rotating assembly 2236, the second rotating assembly 2237, and the belt 2238 is as follows:

[0062] When the wind force is low, the rotation speed of the spiral fan 221 is low. At this time, the rotation speed of the rotating shaft 222 and the first transmission shaft 2234 is also low. At this time, the wind deflector 226 will rotate towards the other wind deflector 226 under the elastic force of the first elastic element and the third elastic element, so as to reduce the air inlet 2242.

[0063] When the wind and sand speed increases, on the one hand, the increased speed of the wind and sand will cause the rotor fan 221 to rotate faster, which in turn will cause the rotating shaft 222 and the first transmission shaft 2234 to rotate faster. On the other hand, when the wind and sand speed increases, the wind pressure will cause the baffle plate 226 to rotate against the elastic force of the first elastic element and the third elastic element, thereby increasing the size of the air inlet 2242. During this process, the rotation of the baffle plate 226 will push the control rod 22391 to move downward. When the control rod 22391 moves downward, it will push the connecting rod 22392 closer to the second fixed wheel 22371. At this time, the distance between the second sliding wheel 22372 and the second fixed wheel 22371 decreases, while the first sliding wheel 22362 and the second sliding wheel 22372 will move away from each other under the tension of the belt 2238. At this time, the connection position of belt 2238 on the second rotating assembly 2237 moves outward, while its position on the first rotating assembly 2236 moves inward. This reduces the transmission ratio between the first drive shaft 2234 and the second drive shaft 2235. That is, when the speed of the first drive shaft 2234 increases, the transmission ratio between the first drive shaft 2234 and the second drive shaft 2235 decreases; and when the speed of the first drive shaft 2234 decreases, the transmission ratio between the first drive shaft 2234 and the second drive shaft 2235 increases, thereby maintaining the rotational speed of the second drive shaft 2235 within a relatively stable range overall.

[0064] In this embodiment, the rack 213 can be disposed on the outer surface of the conveyor belt 212, which makes it easier to mesh the transmission structure 223 with the rack 213. At the same time, the rack 213 can be used to restrict the edge of the transmission belt, preventing sand and dust from sliding down the edge of the conveyor belt 212. Of course, disposing of the rack 213 on the outer surface of the transmission belt is only one implementation method of this embodiment. In other implementation methods, the rack 213 can also be disposed on the inner surface of the transmission belt. However, due to the installation position, it is necessary to add several gears or other transmission structures 223 to transmit the rotation of the third gear 2233 to the rack 213.

[0065] The above are merely preferred embodiments of this application and are not intended to limit this application. Various modifications and variations can be made to this application by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the protection scope of this application.
