Technical Field
[0001] The invention relates to the technical field of water purification, and in particular to a water purification device for river management. Background Art
[0002] Water purification refers to the process in which polluted water gradually restores its original properties through a series of physical, chemical and biological effects. Water purification equipment is needed in the process of purifying water inside some rivers.
[0003] However, in the actual use of the water purification device, when purifying the water inside the river, the water flow inside the river will bring a large amount of garbage and debris in the external water into the river during the flow, and it is easy to cause accumulation inside the river, resulting in pollution of the water inside the river. When purifying the water in the river, there is no measure to filter and remove the garbage and debris in the water flowing into the river. At the same time, the garbage and debris in the water in the river need to be manually salvaged by the staff using tools, which is time-consuming and laborious. And when the garbage and debris in the water in the river contains large pieces of wood, stones, etc., it will also cause damage to the water purification device. Therefore, we propose a new water purification device for river management. Summary of the invention
[0004] The main purpose of the present invention is to provide a water purification device for river management, which can effectively solve the problems in the background technology.
[0005] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is: a water purification device for river management, including columns, two of the columns are symmetrically arranged on both sides of the river, so as to facilitate the cleaning and interception of garbage and debris in the river, one side of the column is fixedly connected with a lifting component 1, the two opposite sides of the lifting components 1 are respectively fixedly connected with fixed blocks, an interception net is fixedly connected between the two fixed blocks, a lifting component 2 is provided on the other side of the two columns, a protective fence is provided on one side of the lifting component 2, a collecting component is provided at the lower part of one side of the interception net, the collecting component includes a collecting trough, a connecting plate, a fixing bolt, and a through hole, the collecting trough is arranged at the lower part of one side of the interception net, and a connecting plate is symmetrically fixedly connected to one side of the top of the collecting trough, the connecting plate is located on the side close to the interception net, the two connecting plates are fixedly connected to the interception net by fixing bolts, and a plurality of through holes are evenly opened at the bottom of the inner cavity of the collecting trough, so that when the interception net is raised, the river water will not be stored in the inner cavity of the collecting trough, and can flow down from the through hole. When too much garbage and debris accumulates on the interception net, the motor is started, so that the active bevel gear drives the driven bevel gear to rotate, thereby driving the threaded rod to rotate. At this time, the vertical rod moves upward along the sleeve rod, thereby driving the fixed block and the interception net to move upward, so that the interception net can be raised. At this time, the garbage and debris on the interception net are affected by gravity and fall into the inner cavity of the collection tank at the bottom of the interception net. The staff only needs to remove the fixing bolts, remove the collection tank, and clean the garbage and debris in the inner cavity of the collection tank, which is convenient for filtering and removing garbage and debris in the water body, and is highly practical.
[0006] As a further description of the above technical solution, a mounting seat is fixedly connected to the bottom of the inner cavity of the column, the mounting seat is located at the bottom of a lifting assembly, the cross-sectional size of the mounting seat is consistent with the cross-sectional size of the sleeve rod, and a non-through mounting groove is opened on the top of the mounting seat.
[0007] As a further description of the above technical solution, the lifting component 1 includes a fixed seat, a driven bevel gear, a threaded rod, a driving bevel gear, a motor, a sleeve rod, a vertical pole, a limit block, and a slide groove. The sleeve rod is fixedly connected to the top of the mounting seat and is located at the top of the mounting groove. The fixed seat is fixedly connected to the bottom of the inner cavity of the mounting groove. The fixed seat is rotatably connected with a threaded rod through a bearing. The driven bevel gear is fixedly sleeved on the threaded rod. The motor is fixedly connected to the side wall of the inner cavity of the mounting groove, and the output end of the motor is fixedly connected with the driving bevel gear, and the driving bevel gear is meshed with the driven bevel gear. A vertical pole is arranged in the sleeve rod, and the threaded rod is meshed with the inner cavity of the vertical pole through a threaded groove. A fixed block is fixedly connected to one side of the vertical pole, and the fixed block is located on the side close to the two vertical poles.
[0008] As a further description of the above technical solution, the two sides of the vertical pole are symmetrically fixedly connected with the limiting blocks, the side walls of the inner cavity of the sleeve rod are symmetrically provided with slide grooves, and the limiting blocks are slidably connected to the inner cavity of the slide groove, which can play a good guiding and limiting role on the vertical pole, making the lifting and lowering of the vertical pole more stable. When it is necessary to purify the water in the river, start the motor so that the active bevel gear drives the driven bevel gear to rotate, thereby driving the threaded rod to rotate. At this time, the vertical pole moves downward along the sleeve rod, thereby driving the fixed block and the interception net to move downward, and the interception net can be lowered between the two columns, so as to intercept, filter and purify the garbage and debris in the river water. The two lifting components drive the interception net to move up and down at the same time, so that the interception net moves quickly and stably, which is convenient for timely interception of garbage and debris in the water body, and no manual operation is required. It effectively reduces the garbage carried by the external water body from entering the interior of the river, causing pollution inside the river, promotes water purification, and facilitates the purification of the water inside the river.
[0009] As a further description of the above technical solution, a non-through fixing groove is opened on the upper part of one side of the column, a fixing plate is fixedly connected to the opening of the fixing groove, a non-through groove is opened on one side of the column, the protective fence is slidably connected to the inner cavity of the groove, the groove plays a good limiting and guiding role for the protective fence, and the fixing groove is located on the outside of the side of the protective fence away from the groove.
[0010] As a further description of the above technical solution, the lifting component 2 includes a second motor, a connecting shaft, a gear, and a rack. The second motor is fixedly connected to the inner cavity of the fixed groove and is fixedly connected to the fixed plate. The output end of the second motor passes through the fixed plate and is fixedly connected to the connecting shaft. The other end of the connecting shaft is rotatably connected to the side wall of another column through a bearing, and the connecting shaft is located on the side of the protective fence away from the groove, and gears are symmetrically fixedly sleeved on the connecting shaft.
[0011] As a further description of the above technical solution, the two racks are symmetrically fixedly connected to both sides of one side of the protective fence, and one side of the rack is meshed with the gear. When the water in the river begins to be purified, when the water potential upstream is too large and the water flow carries a lot of wood, stones, etc., which are easy to damage the interception net, start the second motor to drive the connecting shaft to rotate, so that the gear rotates, and the gear rotates to drive the meshed rack to move downward, thereby driving the protective fence to descend along the groove. When the protective fence descends to the same horizontal position as the interception net, stop the second motor, and the wood and stones in the water flow can be intercepted first to prevent damage to the interception net.
[0012] As a further description of the above technical solution, the collection trough is located between the interception net and the protective fence, and one side of the collection trough is slidably fitted with the protective fence, so that the collection trough can fill the gap between the interception net and the protective fence, so that all the garbage and debris intercepted by the interception net can be collected into the inner cavity of the collection trough, and garbage can be prevented from being blocked between the interception net and the protective fence.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. By setting the lifting component 1, interception net, etc., when the water in the river needs to be purified, start the motor so that the active bevel gear drives the driven bevel gear to rotate, thereby driving the threaded rod to rotate. At this time, the vertical rod moves downward along the sleeve rod, thereby driving the fixed block and the interception net to move downward, and the interception net can be lowered between the two vertical columns to intercept, filter and purify the garbage and debris in the river water. The two lifting components drive the interception net to move up and down at the same time, so that the interception net moves quickly and stably, which is convenient for timely interception of garbage and debris in the water without manual operation. It effectively reduces the garbage carried by the external water body into the interior of the river, causing pollution inside the river, promotes water purification, and facilitates the purification of the water inside the river.
[0014] 2. By setting the lifting component 2, fences, etc., when the water in the river starts to be purified, when the water potential upstream is too high and the water flow carries a lot of wood, stones, etc., which may easily damage the interception net, start the second motor to drive the connecting shaft to rotate, thereby causing the gear to rotate. The rotation of the gear drives the meshing rack to move downward, thereby driving the protective fence to descend along the groove. When the protective fence descends to the same level as the protective net, stop the second motor, so that the wood and stones in the water flow can be intercepted first to prevent damage to the protective net.
[0015] 3. By setting the lifting component 1, the collecting component, etc., when too much garbage and debris are accumulated on the intercepting net, the motor is started, so that the active bevel gear drives the driven bevel gear to rotate, thereby driving the threaded rod to rotate. At this time, the vertical rod moves upward along the sleeve rod, thereby driving the fixed block and the intercepting net to move upward, so that the intercepting net can be raised. At this time, the garbage and debris on the intercepting net are affected by gravity and fall into the inner cavity of the collecting tank at the bottom of the intercepting net. The staff only needs to remove the fixing bolts, remove the collecting tank, and clean the garbage and debris in the inner cavity of the collecting tank, which is convenient for filtering and removing garbage and debris in the water body, and has strong practicality.
