Description

Technical Field

[0001] The utility model relates to the technical field of water filtering equipment, in particular to a sand settling structure and a water retaining weir. Background Art

[0002] Construction operations such as road excavation can easily damage local vegetation, resulting in a large number of exposed construction surfaces. When rainwater erosion occurs during the flood season, it will aggravate soil erosion upstream. These gravel and mud will affect the water quality of downstream water bodies as they flow with rainwater. Therefore, many construction units will build weirs along the river to block the gravel moving with the water flow. When the gravel intercepted at the bottom of the weir is difficult to clean, the long-term accumulation will raise the riverbed height at the weir, causing the water level to rise, thereby reducing the weir's interception effect on gravel.

[0028] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the specific implementation methods of the present invention are described in detail below with reference to the accompanying drawings.

[0029] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art may make similar generalizations without violating the connotation of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in various places throughout this specification does not necessarily refer to the same embodiment, nor does it refer to a separate or selective embodiment that is mutually exclusive with other embodiments.

[0031] Example 1, with reference to Figures 1 to 8 , is the first embodiment of the utility model, which provides a sand settling structure, including a sand settling component 100, including a base 101, and an overflow baffle 102 arranged on one side of the base 101. The overflow baffle 102 is higher than the liquid level of the flowing water. When it is built in the river channel, it will raise the river surface at its location, so that the flowing water will slowly overflow the overflow baffle 102 and flow downstream, and the sand and gravel carried by the flowing water will be intercepted by the overflow baffle 102, thereby completing the interception of the lost sand and gravel. The sand removal component 200 includes a sedimentation chamber 201 opened at the bottom of the base 101, and a sand discharge pipe 203 connected to the sedimentation chamber 201 is installed on the side of the overflow baffle 102 away from the sedimentation chamber 201. A switch 209 for sealing the sand discharge pipe 203 is provided at the connection between the sedimentation chamber 201 and the sand discharge pipe 203, and a collection frame 202 is provided in the sedimentation chamber 201. As Figure 3 As shown, the sedimentation chamber 201 is located at the lowest end of the base 101, so the sand and gravel intercepted by the overflow baffle 102 under the action of gravity will gather in the sedimentation chamber 201. Because a collection frame 202 is provided in the sedimentation chamber 201, most of these sand and gravel will gather in the collection frame 202. After a period of time, the sand and gravel in the collection frame 202 can be processed to prevent them from raising the riverbed height. Because there are multiple holes on the outside of the collection frame 202, some sand and gravel with smaller particle sizes will pass through the holes and gather at the bottom of the sedimentation chamber 201. The staff can first preset a sewage collection tank around it, and discharge this part of the sand and gravel into the sewage collection tank regularly through the switch 209 and the sand discharge pipe 203, waiting for subsequent processing. The drive component 300 includes a drive blade 301 rotatably installed on the side of the overflow baffle 102 away from the sedimentation chamber 201. As shown Figure 1 As shown, the driving blade 301 is arranged at the water outlet end of the overflow baffle 102, and the water flow overflowing above it will drive the driving blade 301 to rotate through impact, so there is no need to set up an additional power source.

[0032] Furthermore, the sand removal assembly 200 also includes a delivery port 210 provided on the base 101, and a flip rack 206 is provided above the delivery port 210, and a flip plate 205 is rotatably installed at the bottom of the collection frame 202. A flip gear 204 is provided on the outside of the collection frame 202 and is coaxially fixed with the flip plate 205, and the flip gear 204 is meshed with the flip rack 206. When it is necessary to clean the sand and gravel in the collection frame 202, it is only necessary to lift the collection frame 202 through the drive assembly 300. During the lifting process, the flip gear 204 provided on the outside of the collection frame 202 engages with the flip rack 206, which drives the flip plate 205 to flip, thereby causing the sand and gravel in the collection frame 202 to obtain an initial velocity and move toward the delivery port 210, thereby passing through the delivery port 210 and falling into a pre-set collection device, thereby completing the cleaning operation of the sand and gravel in the collection frame 202. Compared with the cleaning method using an excavator, the difficulty of cleaning the intercepted sand and gravel is reduced, the operating cost of sand and gravel cleaning is reduced, and it is conducive to the promotion of the equipment.

[0033] Furthermore, the switch member 209 comprises a switch plate 209a rotatably mounted at the connection between the sedimentation chamber 201 and the sand discharge pipe 203. A switch gear 209b is coaxially fixed above the switch plate 209a, and a switch rack 209c engages one side of the switch gear 209b. A reciprocating screw 209d, threadedly connected to the switch rack 209c, is located within the overflow baffle 102. Under normal conditions, the switch plate 209a blocks the sand discharge pipe 203, preventing upstream river water from being directly discharged through the sand discharge pipe 203. Over time, the sand and gravel content in the sedimentation chamber 201 gradually increases. At this point, the switch rack 209c above it can be manipulated by rotating the reciprocating screw 209d. When the switch rack 209c engages the switch gear 209b, it drives the switch plate 209a to rotate and open, allowing the sand and gravel at the bottom of the sedimentation chamber 201 to flow out of the sedimentation chamber 201 under the action of water pressure, thus effectively processing the fine sand and gravel.

[0034] Furthermore, the rotating ends of the flip plate 205 and the switch plate 209a are both positioned away from their center positions. A first limit plate 207 and a second limit plate 208 are respectively provided at the connection points between the collection frame 202, the deposition chamber 201, and the sand discharge pipe 203, which contact the flip plate 205 and the switch plate 209a. The special arrangement of the rotating ends of the flip plate 205 and the switch plate 209a ensures that when pressure is applied to one side, they will contact the first limit plate 207 and the second limit plate 208, achieving a blocking effect.

[0035] When in use, sand and gravel are collected through the setting of the sedimentation chamber 201 and the collection frame 202, and the cooperation of components such as the flip plate 205 and the switch member 209 allows the sand and gravel intercepted at the overflow baffle 102 to be cleaned regularly to prevent them from raising the riverbed and affecting the interception effect of sand and gravel. In addition, compared with the cleaning method using an excavator, the difficulty of cleaning the intercepted sand and gravel is reduced, the operating cost of sand and gravel cleaning is reduced, and it is conducive to the promotion of the equipment.

[0036] Example 2, reference Figures 2 to 7 , which is the second embodiment of the present utility model. Different from the previous embodiment, it further includes a drive assembly 300 and a mounting plate 305 fixedly mounted on the base 101. A drive plate 306 rotatably connected to the base 101 is provided above the mounting plate 305, and a traction rope 307 fixedly connected to the collection frame 202 is fixedly mounted on one end of the drive plate 306. A connecting hole for the traction rope 307 to slide is provided on the mounting plate 305. A synchronous sprocket group 1 302 is provided for transmission between the drive blade 301 and the reciprocating screw rod 209d, a speed reducer 304 is provided at the rotating end of the drive plate 306, and a synchronous sprocket group 2 303 for transmission connection is provided between the reciprocating screw rod 209d and the speed reducer 304. When the device is in use, the driving blade 301 will rotate under the impact of the water flow, and then drive the reciprocating screw 209d to rotate through the synchronous sprocket group 1 302. In addition, the setting of the synchronous sprocket group 2 303 will make the driving plate 306 and the reciprocating screw 209d move synchronously, and use the traction rope 307 to connect them to drive the collection frame 202 to do reciprocating motion in the up and down directions.

[0037] Furthermore, a plurality of anti-friction balls 308 are movably mounted in the connecting hole and are in contact with the traction rope 307. The arrangement of the anti-friction balls 308 converts the sliding friction between the traction rope 307 and the connecting hole into rolling friction, greatly reducing the friction loss of the traction rope 307, thereby increasing its service life.

[0038] Furthermore, the connection between the synchronous sprocket set 1 302 and the driving blade 301 is a rotational connection. The synchronous sprocket set 1 302 and the rotating end of the driving blade 301 are both provided with corresponding spline grooves 309, and a spline shaft 310 is slidably mounted inside the spline groove 309. A fastening screw 311 is coaxially fixed to the side of the spline shaft 310 away from the driving blade 301. The fastening screw 311 is externally threaded with a fastening nut 312. The arrangement of the spline shaft 310 and the spline groove 309 allows the synchronous sprocket set 1 302 to move synchronously with the driving blade 301. When the upstream water gradually becomes clear and the cumulative rate of intercepted sediment slows down, the spline shaft 310 can be disengaged from the spline groove 309 by removing the fastening nut 312, so that the driving blade 301 cannot drive the synchronous sprocket set 1 302 to move, thereby suspending the operation of the sand removal assembly 200 and preventing the upstream water from being accidentally discharged, thereby demonstrating the practicality of the device.

[0039] During use, the driving component 300 is used to drive the operation of the sand removal component 200, thereby ensuring the normal progress of the sand removal work. When the upstream water gradually becomes clear and the cumulative rate of intercepted sediment slows down, the operation of the sand removal component 200 can be suspended by removing the fastening nut 312 to avoid the upstream water from being accidentally discharged, thereby reflecting the practicality of the equipment.

[0040] Example 3, reference Figure 9 , which is the third embodiment of the present invention, further provides a water retaining weir. It includes a filter assembly 400, including a filter screen 401 disposed above the overflow baffle 102, and a filter layer 402 disposed within the filter screen 401. The arrangement of the filter screen 401 and the filter layer 402 allows flowing water to directly pass through the filter layer 402 and over the overflow baffle 102. During the passage, a small amount of sand and gravel in the flowing water is filtered, thereby improving the water retaining weir's ability to intercept sand and gravel.

[0041] Furthermore, the filter layer 402 is filled with sand and gravel. The sand and gravel are fixed together by the filter screen 401, and the gaps inside the sand and gravel facilitate the flow of water. Impurities in the water are larger than the gaps and are therefore retained in the filter layer 402. In this case, the sand and gravel are easily obtained, which greatly reduces the production cost of the equipment.

[0042] When in use, the filter layer 402 is used to filter impurities in the flowing water, thereby improving the interception effect of the water retaining weir on sand and gravel, and the manufacturing cost of the equipment is reduced by utilizing the method of obtaining the raw materials of the filter layer 402 with lower difficulty.

[0043] It is important to note that the construction and arrangement of the present application shown in a number of different exemplary embodiments are merely illustrative. Although only a few embodiments are described in detail in this disclosure, it should be readily understood by those who refer to this disclosure that many modifications are possible (e.g., the size, scale, structure, shape and proportion of various elements, and parameter values ​​(e.g., temperature, pressure, etc.), mounting arrangements, use of materials, colors, directional changes, etc.) without departing substantially from the novel teachings and advantages of the subject matter described in this application. For example, an element shown as integrally formed may be composed of multiple parts or elements, the position of the element may be inverted or otherwise changed, and the nature or number or position of the discrete elements may be altered or changed. Therefore, all such modifications are intended to be included within the scope of the present invention.

[0044] Additionally, in order to provide a concise description of example embodiments, all features of an actual embodiment (ie, those features that are not relevant to the best mode presently contemplated for carrying out the invention or those that are not relevant to implementing the invention) may not be described.
