Description

Technical Field

[0001] This utility model relates to the field of river management devices, and in particular to a river management and flood control device. Background Technology

[0002] With socio-economic development, the protection and management of river water environments have become increasingly important. Various types of floating domestic waste not only severely impact the river landscape but also pose a continuous threat to water quality and ecosystems. To effectively address this problem, existing technologies typically involve installing interception nets or fences in the river to collect and remove floating debris.

[0003] However, existing interception devices generally have a significant drawback in practical applications. River widths vary greatly in nature, and even within the same river channel, different sections often have different widths. Traditional interception devices are mostly fixed-width structures, whose dimensions are difficult to change once manufactured.

[0004] This fixed design severely limits the applicability of the device. When it needs to be installed in a river section narrower than its intended width, it cannot be installed; conversely, when facing a river wider than its intended width, the device cannot completely cover the water surface, leaving noticeable gaps on both sides. This allows large amounts of garbage to float away through these gaps, significantly reducing its interception effect and rendering the pollution control meaningless. This dependence on a specific river width makes the existing device lack versatility and unable to be flexibly deployed in different locations. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a river management and flood control device, which aims to improve the existing river management devices that have a fixed structural width and cannot be adjusted according to changes in river width, resulting in poor versatility and limited application scope. This utility model aims to provide a river management device with an improved structure that can effectively solve the above problems.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a river channel management and flood control device, comprising a double-arm net; and an adjustment component connected to both ends of the double-arm net.

[0007] The adjustment assembly includes a track and a housing that is slidably disposed within the track; one end of the double-arm net is connected to the housing; and multiple fixing holes are provided on the track.

[0008] Furthermore, a sliding plate is slidably disposed inside the housing, and a fixing post for inserting into the fixing hole is fixedly connected to the sliding plate; a groove is formed on the sliding plate; a button is disposed on the housing, and the button is connected to the sliding plate via a moving plate; a rotating bar is rotatably connected inside the housing, and a fixing plate is rotatably connected to the rotating bar, one end of the fixing plate is rotatably connected to the rotating bar, and the other end of the rotating bar is slidably engaged in the groove.

[0009] Preferably, a spring is connected between the sliding plate and the housing.

[0010] Preferably, the river management device further includes a lifting assembly connected to the double-arm net; the lifting assembly includes a protective cover connected to the double-arm net, a sliding column is slidably connected inside the protective cover, and an annular groove is formed on the outer wall of the sliding column.

[0011] Preferably, the lifting assembly further includes a fixed column three, and a rotating column one is slidably disposed within the fixed column three, with one end of the rotating column one being detachably engaged in the annular groove of the sliding column.

[0012] Preferably, the lifting assembly further includes a second button, which is connected to the first rotating column via a baffle and a second fixed column, and the second fixed column and the first rotating column are rotatably connected.

[0013] Preferably, the lifting assembly further includes a rotating bar three, and the button two is rotatably connected around the rotating bar three; the rotating bar three is fixed to the fixing column three through the fixing plate two and the fixing plate three.

[0014] Preferably, a spring is connected between the rotating column one and the fixed column three.

[0015] Preferably, the river management device further includes a positioning rod, which is fixedly connected to both ends of the double-arm net or to the outside of the adjustment component.

[0016] This utility model has the following beneficial effects: 1. In this utility model, by setting a width adjustment component consisting of a track, a housing, a sliding plate controlled by a button, and a fixed column, the problem of the fixed width of existing river management devices, which cannot adapt to rivers of different widths and have poor applicability, is solved. The device can be flexibly extended and reliably locked according to the actual width of the river, thereby greatly improving the versatility and applicability of the device.

[0017] 2. This utility model solves the problem that existing river management devices have a fixed height and cannot cope with changes in water level, resulting in incomplete garbage removal, by setting up a lifting assembly consisting of a protective cover, a sliding column, and a rotating column controlled by a button.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please refer to Figures 1 to 7 This utility model provides a river management and flood control device, which aims to solve the technical problem that existing river management devices have a fixed structure and cannot be adjusted according to changes in river width and water level, resulting in poor applicability.

[0022] like Figure 1 As shown, a river management and flood control device includes a double-arm net 1. The two ends of the double-arm net 1 are connected to adjustment components 2 for adjusting the total length of the double-arm net 1. The double-arm net 1 is also connected to a lifting component 3 for adjusting the overall height of the double-arm net 1. Positioning rods 4 for fixing the entire device to the riverbank are also fixedly connected to both ends of the double-arm net 1.

[0023] Specifically, such as Figure 2 , Figure 3 and Figure 4 As shown, the adjustment component 2 includes a track 202 and a housing 205 slidably disposed in the track 202. One end of the double-arm net 1 is connected to the housing 205, so that when the housing 205 slides in the track 202, it can drive the double-arm net 1 to extend and retract. Multiple fixing holes 201 are provided on the track 202 along the length direction.

[0024] To lock the length of the double-arm net 1, a sliding plate 206 is slidably provided inside the housing 205. A fixing post 209 is fixedly connected to the sliding plate 206. One end of the fixing post 209 passes through a pre-set through hole in the housing 205 and can be selectively inserted into any fixing hole 201 on the track 202, thereby fixing the position of the housing 205. A groove 207 is also provided on the sliding plate 206.

[0025] To control the extension and retraction of the fixed post 209, a button 203 is provided on the housing 205. The button 203 is connected to the sliding plate 206 via a moving plate 204. Pressing the button 203 can drive the sliding plate 206 to slide within the housing 205. A rotating bar 210 is rotatably connected to the inner wall of the housing 205. A fixed plate 211 is rotatably connected to the rotating bar 210. One end of the fixed plate 211 is linked to the sliding plate 206 via a rotating bar 208. Specifically, one end of the fixed plate 211 is rotatably connected to the rotating bar 208, and the other end of the rotating bar 208 is slidably engaged in the groove 207 of the sliding plate 206. When the sliding plate 206 moves, the rotating bar 208 slides in the groove 207 and drives the fixed plate 211 to rotate around the rotating bar 210, thereby forming an unlocking transmission mechanism.

[0026] The lifting assembly 3 and the double-arm net 1 form a specific structural fit and connection relationship, thereby realizing flexible adjustment of the height of the double-arm net 1.

[0027] The lifting assembly 3 includes a protective cover 301, which is fixedly connected to one side of the double-arm net 1. A sliding column 302 is slidably connected inside the protective cover 301. An annular groove is provided on the outer wall of the sliding column 302. The up and down movement of the sliding column 302 can directly drive the protective cover 301 and the double-arm net 1 to lift.

[0028] To lock the height position of the sliding column 302, the lifting assembly 3 also includes a fixed column 307. A rotating column 309 is slidably disposed inside the fixed column 307. One end of the rotating column 309 is detachably engaged in the annular groove of the sliding column 302. When the rotating column 309 is engaged in the annular groove, the position of the sliding column 302 is limited, thereby locking the height of the double-arm net 1.

[0029] To control the separation and engagement of the rotating column 309 and the sliding column 302, the lifting assembly 3 is also equipped with a second button 303. The second button 303 is connected to the rotating column 309 via a baffle 311 and a second fixed column 310. The second fixed column 310 and the rotating column 309 are rotatably connected. This connection method ensures that relative rotation is allowed while transmitting thrust. Pressing the second button 303 will drive the rotating column 309 to move, causing one end of it to disengage from the annular groove of the sliding column 302, thereby releasing the lock on the sliding column 302.

[0030] As a preferred embodiment, in order to provide a stable mounting and rotation reference for button 2 303, the lifting assembly 3 also includes a rotating bar 306, which is rotatably connected around the rotating bar 306. The rotating bar 306 is fixed to the fixing post 307 by fixing plate 2 304 and fixing plate 305. This design makes the pressing action of button 2 303 smooth and reliable.

[0031] As another preferred embodiment, in order to enable the lifting assembly 3 to have the ability to automatically reset and lock, a second spring 308 is also connected between the first rotating column 309 and the third fixed column 307. The second spring 308 is used to drive the first rotating column 309 to reset by elastic force after the second button 303 is released, so that one end of the first rotating column 309 is re-engaged into the annular groove of the sliding column 302.

[0032] As a further preferred embodiment, in order to ensure that the entire river management device can be stably installed on both sides of the river after being adjusted to the appropriate position, the device also includes a positioning rod 4. The positioning rod 4 is fixedly connected to both ends of the double-arm net 1 or the outside of the adjustment component 2. When in use, the positioning rod 4 can be inserted into the soil on both sides of the river.

[0033] Working principle: When adjusting the width of the device, first press button 203 on the adjustment component 2. Button 203 drives sliding plate 206 to slide inside housing 205 through moving plate 204. When sliding plate 206 moves, it drives rotating bar 208 to move through groove 207, which in turn drives fixed plate 211 to rotate around rotating bar 210. This series of transmissions eventually causes fixed post 209 to retract from fixed hole 201, releasing the lock on housing 205. At this time, housing 205 can be manually pushed to slide along track 202 to adjust the total length of double-arm net 1 to adapt to the width of the river. After adjustment, release button 203. Under the elastic force of spring 212, sliding plate 206 drives all transmission mechanisms to reset, so that fixed post 209 is re-inserted into the nearest fixed hole 201, completing the width locking. When adjusting the height of the device, press button 2 303 on the lifting assembly 3. Button 2 303 rotates around the rotating bar 306, driving the rotating column 1 309 to move within the fixed column 307 through the baffle 311 and the fixed column 2 310, causing one end of the rotating column 1 to disengage from the annular groove of the sliding column 302, thus releasing the lock on the sliding column 302. At this time, the sliding column 302 can be manually pulled up or down. The sliding column 302 drives the double-arm net 1 to rise and fall as a whole through the protective cover 301 to match the current water level of the river. After the adjustment is in place, release button 2 303. Under the elastic force of spring 2 308, the rotating column 1 309 resets, and one end of it re-engages into the annular groove of the sliding column 302, completing the height locking.
