Description

Technical Field

[0001] The invention belongs to the technical field of water conservancy projects, and in particular is a sewage interception and purification device for river water ecological restoration. Background Art

[0002] The restoration of river ecological water bodies refers to the process of restoring the structure and function of damaged river ecosystems through scientific means and engineering technologies, so that they can regain their natural ecological characteristics and sustainability.

[0003] Currently, some rivers, influenced by human activities and the natural environment, often contain large amounts of floating debris. The accumulation of floating debris in the river water can hinder the flow of water. It also blocks sunlight, affecting the photosynthesis of aquatic plants, and thus disrupting the balance of the entire aquatic ecosystem, thereby reducing the river's self-purification capacity. Typically, salvage workers use nets from salvage boats to salvage floating debris from the water. However, this method is generally more dispersed in larger rivers, resulting in reduced salvage efficiency.

[0004] Therefore, in order to solve the above problems, a sewage interception and purification device for river water ecological restoration is proposed. Summary of the Invention

[0005] In order to solve the problems raised in the above background technology, the present invention provides a sewage interception and purification device for river water ecological restoration, which solves the problem of low efficiency when operators use salvage boats and scoop nets to salvage floating objects in rivers.

[0006] To achieve the above-mentioned object, the present invention provides the following technical solution: a sewage interception and purification device for river water ecological restoration, comprising a barrier net and a support rod for supporting the barrier net, wherein the support rod is provided with a hook, and the back surface of the barrier net is provided with a plurality of hook ears capable of being hung on the hook, and further comprising: a support seat installed in the river channel and located on the back surface side of the barrier net; and a guide mechanism installed on the support seat; wherein the barrier net is arranged horizontally and obliquely in the river channel; The guide mechanism includes a reduction gearbox fixedly mounted on the top of the support base, the input end of the reduction gearbox is transmission-connected to the fan blade assembly, the output end of the reduction gearbox is transmission-connected to the transmission rod, the other end of the transmission rod is fixedly mounted to a plate, and the plate is equidistantly provided with shift rods; The fan blade assembly and the shifting rod are respectively located on the back water surface and the front water surface of the barrier net.

[0007] Preferably, a storage area is reserved at one end of the barrier net.

[0008] Preferably, a pin which can be inserted into the hook ear is fixedly mounted on the support seat, and the hook ear can be hung above the pin. The pin is located on the back water side of the barrier net and can support the barrier net.

[0009] Preferably, one end of the shaft portion of the fan blade assembly is fixedly connected to a buoyancy cylinder, and the other end of the buoyancy cylinder is fixedly connected to a universal joint, and the fan blade assembly is transmission-connected to the output shaft of the reduction gearbox via the universal joint.

[0010] Preferably, the lever is a telescopic lever and is provided with a tension spring inside, and the lever can be completely retracted into the plate in a natural state, a through hole 1 is provided at the bottom of the lever, and a flow channel that can communicate with the plurality of groups of through holes 1 is provided in the plate; The support seat is also provided with an adjusting pump mechanism, in which hydraulic oil is stored and can be pumped into the flow channel to push the shifting rod to extend.

[0011] Preferably, the cavity of the transmission rod is in communication with the flow channel; The regulating pump mechanism includes a guide rail mounted on the top of the support seat, a piston sleeve fixedly mounted on the guide rail, a piston rod movably sleeved in the piston sleeve, one end of the piston rod is movably sleeved on the outside of the guide rail, a synchronous sleeve is fixedly sleeved on the outside of the transmission rod, a through hole 2 connected to the transmission rod cavity is opened on the synchronous sleeve, the piston sleeve and the piston rod are movably sleeved on the outside of the synchronous sleeve, and the piston sleeve cavity is connected to the transmission rod cavity through the through hole 2; A guide groove is provided on the outer periphery of the synchronization sleeve, and a convex shaft capable of sliding in the guide groove is fixedly connected to one end of the piston rod; When the synchronous sleeve rotates, the piston rod can slide in the guide groove and drive the piston rod to move back and forth.

[0012] Preferably, the guide groove includes an arc groove, an oblique groove and a straight groove, and when the guide groove rotates with the synchronous sleeve, the cam can slide along the arc groove, the oblique groove and the straight groove in sequence; When the convex shaft is located at the connection between the arc groove and the oblique groove, the shifting rod is located above the water body, and the width of the arc groove and the oblique groove is greater than the width of the convex shaft, the arc groove and the oblique groove.

[0013] Preferably, the regulating pump mechanism can also adopt a combination of a micro pump body and an oil storage tank to intermittently pump and extract hydraulic oil into the flow channel.

[0014] Compared with the prior art, the present invention has the following beneficial effects: The above solution intercepts floating objects in the river channel through a barrier net. The flowing water passes through the hook ear and drives the fan blade assembly to rotate. Then, after being decelerated by the reduction gearbox, it drives the transmission rod and plate to rotate, and finally the lever rotates around the axis and scrapes the floating objects blocked on the water-facing side of the barrier net toward the storage area. Over time, the floating objects will eventually accumulate in the storage area, at which point operators can salvage these accumulated floating objects on the shore, thus solving the problem of low efficiency when operators use salvage boats and scoop nets to salvage floating objects in the river channel. When the transmission rod rotates, the above-mentioned solution also drives the shift rod and the guide groove to rotate. The relative cam shaft reciprocates along the guide groove, thereby causing the piston rod to reciprocate and pump the hydraulic oil in the piston sleeve into the through hole 1 through the second through hole, the cavity of the transmission rod and the flow channel to extend the shift rod, or to draw the hydraulic oil in the shift rod into the piston sleeve through the through hole 1 to retract the shift rod into the plate. At this time, the floating objects remaining on the shift rod will be separated from the shift rod, thereby preventing the floating objects from accumulating on the shift rod. The above scheme is that when the lever is rotated into the water, the convex shaft moves from the straight groove to the arc groove. When the lever revolves around the shaft and is rotated out of the water, the convex shaft rotates from the arc groove to the inclined groove. At this time, under the action of the lever's own elastic force, it will shrink and reset to the plate. At this time, the hydraulic oil in the lever will enter the piston sleeve through the through hole 1, the flow channel, the cavity of the transmission rod and the through hole 2 and push the piston rod to reset, so as to facilitate the next cycle of the device. At the same time, it also ensures that the lever can stably push floating objects in the water to move when it is in the water. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0018] like Figures 1 to 10 As shown, the present invention provides a sewage interception and purification device for river water ecological restoration, comprising a barrier net 1 and a support rod 2 for supporting the barrier net 1, wherein the support rod 2 is provided with a hook 21, and the back surface of the barrier net 1 is provided with a plurality of hook ears 11 that can be hung on the hook 21. The device also includes: a support base 3 installed in the river and located on the back surface of the barrier net 1; a guide mechanism 4 installed on the support base 3; wherein the barrier net 1 is arranged horizontally and obliquely in the river channel; The guide mechanism 4 includes a reduction gearbox 42 fixedly mounted on the top of the support base 3. The input end of the reduction gearbox 42 is transmission-connected to the fan blade assembly 41, and the output end of the reduction gearbox 42 is transmission-connected to the transmission rod 43. The other end of the transmission rod 43 is fixedly mounted with a plate 44, and the plate 44 is equidistantly provided with a shifting rod 45. The fan blade assembly 41 and the shifting rod 45 are respectively located on the back water side and the front water side of the barrier 1. A storage area 12 is reserved at one end of the barrier 1; The support seat 3 is also fixed with a latch 31 that can be inserted into the hook ear 11. The hook ear 11 can be hung above the latch 31. The latch 31 is located on the back surface of the barrier net 1 and can support the barrier net 1. By adopting the above scheme, floating objects in the river channel are intercepted by the barrier net 1, and the flowing water will pass through the hook ear 11 and drive the fan blade assembly 41 to rotate, and then after deceleration by the reduction gear box 42, it can drive the transmission rod 43 and the plate 44 to rotate, and finally make the lever 45 rotate around the axis and scrape the floating objects blocked on the water-facing surface of the barrier net 1 toward the storage area 12. As time goes by, the floating objects will eventually accumulate in the storage area 12. At this time, the operator can salvage these accumulated floating objects on the shore, thereby solving the problem of low efficiency of operators using salvage boats and scoop nets to salvage floating objects in the river channel.

[0019] like Figure 1-Figure 5 and Figure 10 As shown, one end of the shaft portion of the fan blade assembly 41 is fixedly connected to a buoyancy cylinder 412, and the other end of the buoyancy cylinder 412 is fixedly connected to a universal joint 411. The fan blade assembly 41 is transmission-connected to the output shaft of the reduction gearbox 42 via the universal joint 411; By adopting the above scheme, the setting of the universal joint 411 ensures that the fan blade assembly 41 can be consistent with the flow direction of the river water, and the setting of the buoyancy tube 412 ensures that the universal joint 411 can float stably on the water surface, and the universal joint 411 can also float up and down within a certain range following the water surface height, thereby improving the adaptability of the device.

[0020] like Figures 4-10 As shown, the lever 45 is a telescopic rod and is provided with a tension spring inside. The lever 45 can be completely retracted into the plate 44 in a natural state. A through hole 451 is formed at the bottom of the lever 45, and a flow channel 441 is formed in the plate 44 that can communicate with a plurality of groups of through holes 451. The support base 3 is also provided with an adjusting pump mechanism 5, which stores hydraulic oil and can pump it into the flow channel 441 to push the lever 45 to extend; The cavity of the transmission rod 43 is communicated with the flow channel 441; the regulating pump mechanism 5 includes a guide rail 51 mounted on the top of the support base 3, a piston sleeve 52 is fixedly mounted on the guide rail 51, a piston rod 53 is movably sleeved in the piston sleeve 52, and one end of the piston rod 53 is movably sleeved on the outside of the guide rail 51, a synchronization sleeve 54 is fixedly sleeved on the outside of the transmission rod 43, and a second through hole 55 is opened on the synchronization sleeve 54 and communicated with the cavity of the transmission rod 43, the piston sleeve 52 and the piston rod 53 are both movably sleeved on the outside of the synchronization sleeve 54, and the cavity of the piston sleeve 52 is communicated with the cavity of the transmission rod 43 through the second through hole 55; A guide groove 6 is formed on the outer periphery of the synchronization sleeve 54, and a convex shaft 531 that can slide in the guide groove 6 is fixedly connected to one end of the piston rod 53; When the synchronization sleeve 54 rotates, the piston rod 53 can slide in the guide groove 6 and drive the piston rod 53 to move back and forth.

[0021] With the above solution, when the transmission rod 43 rotates, the shift rod 45 and the guide groove 6 are also driven to rotate. The relative cam 531 reciprocates along the guide groove 6, thereby causing the piston rod 53 to reciprocate and pump the hydraulic oil in the piston sleeve 52 into the through hole 1 451 through the second through hole 55, the cavity of the transmission rod 43 and the flow channel 441, thereby extending the shift rod 45. Alternatively, the hydraulic oil in the shift rod 45 is pumped into the piston sleeve 52 through the through hole 1 451, thereby retracting the shift rod 45 into the plate 44. At this time, floating objects remaining on the shift rod 45 will be separated from the shift rod 45, thereby preventing the floating objects from accumulating on the shift rod 45. It is worth noting that the regulating pump mechanism 5 can also use a combination of a micro pump body and an oil storage tank to intermittently pump and extract hydraulic oil into the flow channel 441. Compared with the above-mentioned mechanical structure for pumping hydraulic oil into the flow channel 441, it is more stable and adaptable, but is lower than the above-mentioned mechanical mechanism in terms of energy saving.

[0022] like Figures 4-10 As shown, the guide groove 6 includes an arcuate groove 61, an oblique groove 62 and a straight groove 63. When the guide groove 6 rotates with the synchronous sleeve 54, the convex shaft 531 can slide along the arcuate groove 61, the oblique groove 62 and the straight groove 63 in sequence; When the convex shaft 531 is located at the connection between the arc groove 61 and the oblique groove 62, the lever 45 is located above the water body, and the width of the arc groove 61 and the oblique groove 62 is greater than the width of the convex shaft 531 and the arc groove 61 and the oblique groove 62; By adopting the above scheme, during the process of the lever 45 being rotated into the water body, the convex shaft 531 will move from the straight groove 63 to the arc groove 61. When the lever 45 is rotated around the axis and out of the water body, the convex shaft 531 will be rotated from the arc groove 61 into the inclined groove 62. At this time, under the action of the elastic force of the lever 45 itself, it will shrink and reset to the plate 44. At this time, the hydraulic oil in the lever 45 will enter the piston sleeve 52 through the through hole 1 451, the flow channel 441, the cavity of the transmission rod 43 and the through hole 2 55 and push the piston rod 53 to reset. The setting of the redundant width of the arc groove 61 ensures that when the synchronous sleeve 54 rotates slowly, the convex shaft 531 has enough space to reset to facilitate the next cycle of the device. At the same time, it also ensures that when the lever 45 is in the water body, it can stably push the floating objects in the water body to move.

[0023] The working principle and use process of the present invention: First, the operator places the barrier net 1 horizontally and obliquely in the river channel using the support rod 2, with the top of the barrier net 1 extending out of the water. The operator then inserts the support base 3 into the river channel and inserts the latch 31 into the hook ear 11, positioning it on the backwater side of the barrier net 1. At the same time, the fan blade assembly 41 and the lever 45 are placed on the backwater side and the frontwater side of the barrier net 1, respectively. During the flow of water, the barrier net 1 intercepts floating objects in the river channel, and the flowing water passes through the hook ear 11 and drives the blade assembly 41 to rotate. Then, after being decelerated by the reduction gear box 42, it drives the transmission rod 43 and the plate 44 to rotate, and finally causes the lever 45 to rotate around the axis and scrape the floating objects blocked on the water-facing side of the barrier net 1 toward the storage area 12. As time goes by, the floating objects will eventually accumulate in the storage area 12, and the operator can then salvage these accumulated floating objects on the shore. When the transmission rod 43 rotates, it also drives the shift rod 45 and the guide groove 6 to rotate. The relative convex shaft 531 reciprocates along the guide groove 6, thereby causing the piston rod 53 to reciprocate and pump the hydraulic oil in the piston sleeve 52 into the through hole 1 451 through the second through hole 55, the cavity of the transmission rod 43 and the flow channel 441, thereby extending the shift rod 45. Alternatively, the hydraulic oil in the shift rod 45 is pumped into the piston sleeve 52 through the through hole 1 451, thereby retracting the shift rod 45 into the plate 44. At this time, floating objects remaining on the shift rod 45 will be separated from the shift rod 45, thereby preventing the floating objects from accumulating on the shift rod 45. When the lever 45 is rotated into the water, the convex shaft 531 will move from the straight groove 63 to the arc groove 61. When the lever 45 is rotated around the axis and out of the water, the convex shaft 531 will be rotated from the arc groove 61 to the inclined groove 62. At this time, under the action of the elastic force of the lever 45 itself, it will shrink and return to the plate 44. At this time, the hydraulic oil in the lever 45 will enter the piston sleeve 52 through the through hole 1 451, the flow channel 441, the cavity of the transmission rod 43 and the through hole 2 55 and push the piston rod 53 to return to its original position, so as to facilitate the next cycle of the device. At the same time, it also ensures that the lever 45 can push floating objects in the water to move when it is in the water.
