Description

Technical Field

[0001] The invention relates to the technical field of river channel dredging, and in particular to a silt separation and purification baffle for river channel regulation. Background Art

[0002] River desilting refers to the removal of silt, garbage and other debris in the river through mechanical or manual means to keep the river unobstructed, prevent flood disasters, improve the water quality environment and maintain ecological balance.

[0003] The existing technology can change the direction and speed of water flow by setting baffles in the river channel, which helps to deposit silt, debris, etc. in the water flow near the baffle, which is convenient for subsequent cleaning work. However, this baffle does not have a local silt transport function and still needs to be operated with the help of excavators and other equipment to excavate the silt in the water and lay it on the dry side of the riverbed for exposure to the sun. In addition, during the operation of the excavator, it is easy for the excavator to excavate excessively, causing water to be discharged from the bottom of the baffle, affecting the overall silt separation work. For this reason, we propose a silt separation and purification baffle for river management to solve the above problems. Summary of the invention

[0004] The object of the present invention is to provide a silt separation and purification baffle for river management to solve the problems raised in the above-mentioned background technology.

[0006] An articulated frame is provided on the top of the transmission mechanism, and the articulated frame is rotatably arranged on the outside of a pair of clamping blocks at the top. The articulated frame is used to block suspended matter on the water surface. When the silt on the riverbed needs to be cleaned and exposed to the sun, the positioning shaft can be set on both sides of the riverbed. The river water can be intercepted by means of the movable frame, and the silt at the bottom of the riverbed can be accumulated at the bottom of the movable frame along the water flow. As the transmission mechanism operates, the silt at the bottom can be transmitted to the other side of the movable frame.

[0007] Preferably, a blocking plate is installed at the bottom of the movable frame, and the blocking plate is used to be inserted at the bottom of the riverbed. A plurality of arc-shaped plug rods are installed at the bottom of the blocking plate, and the arc-shaped plug rods are arranged in a uniform array at the bottom of the blocking plate. The blocking plate can play a blocking role to avoid the situation where the drainage impacts the other end of the riverbed due to excessive excavation during silt transportation.

[0008] Preferably, a plurality of breaking rods are installed on the movable frame, and the breaking rods are arranged in a uniform array inside the rectangular groove. A plurality of tooth grooves are opened on the breaking rods, and the breaking rods can cooperate with the conveyor belt to quickly shake off the vines and the like remaining on the conveyor belt, thereby reducing impurities mixed in the sludge.

A plurality of separation shafts are installed at the bottom of the guide plate. The separation shafts are arc-shaped. An elastic rod is installed at one end of each separation shaft. A plurality of fixed baffles are installed on the separation shaft. The fixed baffles and the separation shafts are vertically staggered. The fixed baffles cooperate with the separation shafts to separate and intercept plant roots in the sludge, thereby preventing plants from mixing into the sludge and growing, and preventing the roots from entangled and causing sludge clumping at the bottom.

[0010] Preferably, a plurality of positioning plates are fixedly connected to the surface of the conveyor belt, and the positioning plates are evenly arranged on the surface of the conveyor belt. Positioning holes are opened at the tops of the positioning plates, and movable plug rods are inserted into the positioning holes to facilitate disassembly and maintenance;

[0011] A reset plate is clamped on the movable plug rod, and both ends of the reset plate are installed on both sides of the positioning plate. A plurality of straight grooves are opened on the surface of the reset plate, and the straight grooves are used for auxiliary drainage, which can reduce the water content of the sludge and shorten the subsequent drying time.

[0012] Preferably, a plurality of compression shafts are installed between the positioning plates, and the compression shafts are arranged between the positioning plates in a uniform array;

[0013] When the positioning plate is transferred to the roller, the compression shaft can be deformed to assist in pushing down the sludge accumulated on the reset plate, thereby reducing the accumulation of sludge during transportation.

A reset shaft is movably clamped at the top of the articulated frame, and a slide groove is provided inside the reset shaft. A welding block is installed at the top of the articulated frame, and the reset shaft is clamped on the welding block, and a reset spring is installed between the inside of the slide groove and the welding block. A rectangular frame is installed at one end of the reset shaft, and a reset plate is installed outside the rectangular frame.

[0015] A plurality of storage racks are installed on the reset plate. The storage racks are elastic and have hook shapes at both ends. A plurality of metal barbs are arranged on the outer walls at both ends of the storage racks, which can enhance the limiting effect on the garbage and reduce the situation of separation under the impact of water flow.

[0016] Preferably, a pair of limit rods are installed on the top of the articulated frame, a pair of telescopic rods are installed on the outer wall of the reset shaft, a guide rail shaft is installed at one end of the telescopic rod, the guide rail shaft is arc-shaped and has a through groove on the surface, the limit rod is clamped inside the through groove, one end of the guide rail shaft is clamped between the rectangular frames, the reset plate is abutted against one end of the guide rail shaft, the reset plate can be squeezed with the help of the guide rail shaft, and the garbage stuck inside the storage rack can be prevented from falling off along the water flow.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention can drive the conveyor belt to rotate during the operation of the rotating shaft, and can clamp the silt at the bottom of the riverbed on the reset plate. Under the support of the movable plug rod, the silt can be transported to the top of the movable frame and thrown to the other side of the riverbed, thereby playing a role in transportation;

[0019] 2. When the silt falls on the top of the guide plate, the present invention can screen out the silt from the gap by means of the staggered arrangement of the separation shaft and the fixed baffle. The plant roots or vines mixed in the silt are stuck on the separation shaft for exposure to the sun. The staggered vines can also be cut by means of the fixed baffle to prevent the silt from mixing and accumulating, which affects the efficiency of subsequent paving and drying.

[0020] 3. The present invention uses external pumping equipment to pump water from the interception side to prevent the water level from being too high. The water flow can push the rectangular frame and the reset plate to move, and the rectangular frame and the reset plate can swing under the change of the water flow impact force. The floating garbage on the water surface can be stuck inside the storage rack to prevent it from being mixed into the silt along the water flow.

[0021] 4. When the rectangular frame and the reset plate reciprocate, the guide rail shaft can move along the direction of the telescopic rod under the action of the limit rod, so that one end of the reset plate can be squeezed and the floating garbage between the storage rack and the reset plate can be squeezed and compacted, so that it is stuck on the metal barb, which is convenient for subsequent unified cleaning.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. 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 creative work are within the scope of protection of the present invention.

[0031] See also Figure 1-Figure 7 The present invention provides a technical solution: a sludge separation and purification baffle for river channel management, comprising a positioning shaft 1, a movable frame 2 installed at one end of the positioning shaft 1, and a guide plate 3 and a transmission mechanism 4 installed on the movable frame 2. A hinge rod is installed at one end of the positioning shaft 1, and the movable frame 2 is rotatably arranged on the hinge rod. A rectangular groove is opened on the surface of the movable frame 2, and the transmission mechanism 4 is arranged inside the rectangular groove. The transmission mechanism 4 includes a plurality of clamping blocks 41, and the clamping blocks 41 are clamped on the inner walls at both ends of the rectangular groove. Rollers are installed between the clamping blocks 41, and a conveyor belt 42 is rotatably arranged on the roller for transporting sludge accumulated at the bottom of one side of the movable frame 2, and the guide plate 3 is arranged at the top of the movable frame 2;

[0032] An articulated frame 5 is provided on the top of the transmission mechanism 4. The articulated frame 5 is rotatably arranged on the outside of a pair of clamping blocks 41 at the top. The articulated frame 5 is used to block suspended matter on the water surface. When the silt on the riverbed needs to be cleaned and exposed to the sun, the positioning shaft 1 can be set on both sides of the riverbed. The river water can be intercepted with the help of the movable frame 2, and the silt at the bottom of the riverbed can be accumulated at the bottom of the movable frame 2 along the water flow. As the transmission mechanism 4 runs, the silt at the bottom can be transmitted to the other side of the movable frame 2, and in the process of transmission, the silt can be further separated with the help of the guide plate 3, and the storage rack 56 on one side of the articulated frame 5 can collect garbage floating on the river surface to prevent it from mixing into the silt.

[0033] like Figure 5 As shown, in order to ensure the stability of subsequent silt excavation, a blocking plate 21 is installed at the bottom of the movable frame 2. The blocking plate 21 is used to be inserted at the bottom of the riverbed. A plurality of arc-shaped plug rods are installed at the bottom of the blocking plate 21, and the arc-shaped plug rods are arranged in a uniform array at the bottom of the blocking plate 21. The position of the blocking plate 21 is lower than the transmission mechanism 4, which can prevent the accidental situation in which the bottom is dug through due to the excavation of the aisle during the semicircle of silt excavation.

[0034] like Figure 5 In order to reduce the amount of aquatic plants remaining on the transmission mechanism 4, a plurality of breaking rods 22 are installed on the movable frame 2. The breaking rods 22 are arranged in a uniform array inside the rectangular groove. A plurality of tooth grooves are opened on the breaking rods 22. The breaking rods 22 can cooperate with the conveyor belt 42 to quickly shake off the vines remaining on the conveyor belt 42. During the transmission process, the roots and vines entangled on the conveyor belt 42 can be stuck in the tooth grooves. As the conveyor belt 42 moves, it can prevent them from being entangled and intertwined on the conveyor belt 42.

[0035] like Figure 7 As shown, in order to reduce the situation where other garbage or aquatic plants are mixed in the sludge, the guide plate 3 is installed at the top of the movable frame 2 and on the side away from the transmission mechanism 4. The extended end of the guide plate 3 is arc-shaped, and a plurality of separation shafts 31 are installed at the bottom of the guide plate 3. The separation shafts 31 are arc-shaped, and elastic rods 32 are installed at one end of the separation shafts 31. A plurality of fixed baffles 33 are installed on the separation shafts 31. The fixed baffles 33 and the separation shafts 31 are vertically staggered. The fixed baffles 33 cooperate with the separation shafts 31 to separate and intercept plant roots in the sludge, and the sludge is shaken off. When at the top of the guide plate 3, the separation shaft 31 and the fixed baffle 33 can be staggered to screen out the silt from the gap, and the plant roots or vines mixed in the silt can be stuck on the separation shaft 31 for exposure to the sun. When they are dehydrated and dead, they can fall into the silt, which can avoid the situation in which the silt is clumping and inconvenient to dry due to the growth of plants during the subsequent exposure process. In addition, as the silt is being transmitted, the fixed baffle 33 can be used to cut the intertwined vines to prevent the silt from being mixed and accumulated, which affects the efficiency of subsequent paving and drying.

[0036] like Figure 6 As shown, in order to ensure the stability of sludge transportation, a plurality of positioning plates 43 are fixedly connected to the surface of the conveyor belt 42. The positioning plates 43 are evenly arranged on the surface of the conveyor belt 42. Positioning holes are opened at the tops of the positioning plates 43, and movable plug rods 44 are inserted into the positioning holes for easy disassembly and maintenance.

[0037] A reset plate 45 is provided on the movable plug rod 44, and both ends of the reset plate 45 are installed on both sides of the positioning plate 43. A plurality of straight grooves are provided on the surface of the reset plate 45, and the straight grooves are used to assist drainage. During the operation of the rotating shaft, the conveyor belt 42 can be driven to rotate, and the silt at the bottom of the riverbed can be fixed on the reset plate 45. With the support of the movable plug rod 44, the silt can be transported to the top of the movable frame 2 and thrown to the other side of the riverbed, which plays a role in transportation. Compared with separation by an excavator, it is more efficient and convenient.

[0038] like Figure 6 As shown, since silt is easily stuck on the surface of the conveyor belt 42 during transportation, a plurality of compression shafts 46 are installed between the positioning plates 43, and the compression shafts 46 are arranged between the positioning plates 43 in a uniform array;

[0039] When the positioning plate 43 is transmitted to the roller, the compression shaft 46 can be deformed, which is used to assist in pushing down the sludge accumulated on the reset plate 45. When the sludge is transmitted to the top of the movable frame 2, when the conveyor belt 42 moves around the rotating axis, the compression shaft 46 can be deformed outward, which can push down the sludge accumulated on the reset plate 45 and reduce the accumulation of sludge.

[0040] like Figure 3 As shown, in order to reduce the suspended garbage debris and the like laid on the conveyor belt 42, a pair of movable shafts 51 are installed at the bottom of the articulated frame 5, and the movable shaft 51 is rotatably arranged on the outside of the clamping block 41 at the top. A reset shaft 52 is movably clamped at the top of the articulated frame 5, and a slide groove is provided inside the reset shaft 52. A welding block is installed at the top of the articulated frame 5, and the reset shaft 52 is clamped on the welding block, and a reset spring is installed between the inside of the slide groove and the welding block. A rectangular frame 55 is installed at one end of the reset shaft 52, and a reset plate 551 is installed outside the rectangular frame 55.

[0041] A plurality of storage racks 56 are installed on the reset plate 551. The storage racks 56 are elastic and have hook-shaped ends. A plurality of metal barbs are provided on the outer walls at both ends of the storage racks 56. With the help of external pumping equipment, water is pumped out on the interception side to prevent the water level from being too high. Under the action of the water flow, the rectangular frame 55 and the reset plate 551 can be pushed to move, and can swing under the change of the impact force of the water flow. Floating garbage on the water surface can be stuck inside the storage rack 56, which can reduce the garbage and the like from being stuck on the surface of the conveyor belt 42 during transportation along the water flow, resulting in the mixing of silt and garbage, thereby affecting the purification efficiency.

[0042] like Figure 4 As shown, the garbage limited on the storage rack 56 is also easy to be separated under the continuous impact of the water flow. A pair of limiting rods 54 are installed at the top of the articulated frame 5, and a pair of telescopic rods 521 are installed on the outer wall of the reset shaft 52. A guide shaft 53 is installed at one end of the telescopic rod 521. The guide shaft 53 is arc-shaped and has a through groove on the surface. The limiting rod 54 is clamped inside the through groove, and one end of the guide shaft 53 is clamped between the rectangular frame 55. The reset plate 551 is against one end 53 of the guide shaft. When the rectangular frame 55 and the reset plate 551 reciprocate, the guide shaft 53 can move along the direction of the telescopic rod 521 under the action of the limiting rod 54, and one end of the reset plate 551 can be squeezed, so that the floating garbage between the storage rack 56 and the reset plate 551 can be squeezed and compacted, so that it is clamped on the metal barb to prevent it from being separated from the storage rack 56 under the action of the water flow.

[0043] Working principle: First, when the silt on the riverbed needs to be cleaned and exposed to the sun, the positioning shaft 1 can be set on both sides of the riverbed, and the river water can be intercepted by the movable frame 2, so that the silt at the bottom of the riverbed can be accumulated at the bottom of the movable frame 2 along the water flow. As the transmission mechanism 4 operates, the silt at the bottom can be transmitted to the other side of the movable frame 2, and in the transmission process, the silt can be further separated by the guide plate 3, and the storage rack 56 on one side of the articulated frame 5 can collect the garbage floating on the river surface to prevent To prevent the silt from being mixed into the silt, and with the operation of the rotating shaft, the conveyor belt 42 can be driven to rotate, and the silt at the bottom of the riverbed can be stuck on the reset plate 45. Under the support of the movable plug rod 44, the silt can be transported to the top of the movable frame 2 and thrown to the other side of the riverbed, playing a role in transportation. When the silt is transported to the top of the movable frame 2, when the conveyor belt 42 moves around the rotating shaft, the compression shaft 46 can be deformed outward, and the silt accumulated on the reset plate 45 can be pushed down, reducing the accumulation of silt.

[0044] Then, when the silt is shaken off the top of the guide plate 3, the separation shaft 31 and the fixed baffle 33 can be staggered to screen the silt from the gap, and the plant roots or vines mixed in the silt can be stuck on the separation shaft 31 for exposure to the sun. When they are dehydrated and dead, they can fall into the silt, which can avoid the situation in which the silt is agglomerated and inconvenient to dry due to the growth of plants during the subsequent exposure process. In addition, as the silt is being transported, the staggered vines can be cut with the help of the fixed baffle 33 to prevent the silt from being mixed and accumulated, which affects the efficiency of subsequent paving and drying.

[0045] Finally, with the help of external pumping equipment, the water on the interception side is pumped out to prevent the water level from being too high. Under the action of the water flow, the rectangular frame 55 and the reset plate 551 can be pushed to move, and can swing under the change of the impact force of the water flow, so that the floating garbage on the water surface can be stuck inside the storage rack 56 to prevent it from being mixed into the silt along the water flow. As the rectangular frame 55 and the reset plate 551 reciprocate, the guide shaft 53 can move along the direction of the telescopic rod 521 under the action of the limit rod 54, so that one end of the reset plate 551 can be squeezed, and the floating garbage between the storage rack 56 and the reset plate 551 can be squeezed and compacted, so that it can be stuck on the metal barb, which is convenient for subsequent unified cleaning.

[0046] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
