Description

Technical Field

[0001] This utility model relates to the technical field of water conservancy engineering protection devices, specifically a channel seepage prevention and protection device. Background Technology

[0002] Canals, which are artificial waterways with free water surfaces, can be classified according to their uses, such as irrigation canals, power canals, water supply canals, navigation canals, and drainage canals. In general, canals do not have a single function but combine multiple uses. However, canal leakage not only leads to water waste but may also cause groundwater level rise, which in turn leads to a series of problems such as soil salinization and marshland formation. In addition, canals are also subject to risks such as erosion, siltation, and collapse, requiring frequent maintenance and repair. Therefore, it is particularly important to develop a canal seepage prevention and protection device.

[0003] A channel seepage prevention and protection device, such as the one disclosed in CN216865037U, includes a foundation, a cement layer, and a first waterproof layer. A base is symmetrically installed on the upper surface of the foundation, and a cement layer is provided on the upper surface of the base. A screw is welded to the center of the upper surface of the base. A suspension is installed above the foundation, and a protective plate is installed on the lower surface of the suspension. A first waterproof layer and a second waterproof layer are provided between the base and the cement layer. The lower end of the first waterproof layer has equidistant seepage holes, and the second waterproof layer has a connecting pipe inside. This invention uses the protective plate to provide compression protection to cracks or joints in the cement layer, preventing continuous water impact on damaged areas and effectively improving the protective effect of the device. Simultaneously, the seepage holes allow infiltrated water to drain through the connecting pipe, preventing foundation settlement and effectively improving the practicality of the device.

[0004] The aforementioned patent proposes that by attaching the protective plate to the cement layer through the base, the protective plate can isolate the damaged parts of the cement layer, preventing the cracks from being soaked and impacted by water flow for a long time, thus preventing them from widening. At the same time, water seeping into the first waterproof layer is discharged by a water pump through seepage holes and connecting pipes, ensuring the dryness of the first and second waterproof layers. Since the water contains silt, in sloping channels, silt tends to accumulate at the bottom of the slope. This not only reduces the water flow speed but also damages the structure of the channel.

[0005] Therefore, we propose a channel seepage prevention and protection device to solve the problems mentioned above. Utility Model Content

[0006] The purpose of this utility model is to provide a channel seepage prevention and protection device to solve the problem mentioned in the background art, where silt and sand are easily accumulated at the bottom of the slope in sloping channels due to water carrying silt and sand. This not only reduces the water flow speed but also damages the channel structure.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a channel seepage prevention and protection device, including a base and a cover plate movably installed on the top surface of the base, a movable cover is slidably embedded in the top surface of the cover plate, a cleaning pipe is fixedly installed on the bottom surface of the cover plate, a cleaning structure is rotatably installed in the inner cavity of the base, and a hidden pipe drainage system is fixedly installed through the bottom of the base.

[0008] Preferably, the top of the base is covered with an impermeable layer, the bottom of the inner cavity of the base is provided with a sedimentation tank, the groove of the sedimentation tank corresponds to the opening of the cleaning pipe, the two ends of the middle part of the base are provided with trapezoidal circular grooves, and the bottom of the base is provided with a hidden ditch, and the hidden pipe drainage system is fixedly installed in the hidden ditch.

[0009] Preferably, the impermeable layer includes a concrete layer and a sand layer laid on the bottom surface of the concrete layer, a geotextile is laid on the bottom surface of the sand layer, and a plastic film is laid on the bottom surface of the geotextile.

[0010] Preferably, the cover plate has a through hole, and the movable cover is embedded and slidably inserted into the inner cavity of the through hole, which is connected to the cleaning pipe.

[0011] Preferably, the movable cover includes a movable plate and lifting rings respectively fixedly installed on both sides of the top surface of the movable plate.

[0012] Preferably, the cleaning structure includes a waterwheel and limiting rings that are movably installed on both sides of the waterwheel. A central shaft is movably installed through the center of the waterwheel, and protrusions are fixedly installed on both sides of the central shaft. The protrusions are embedded and fixedly installed in the inner cavity of the trapezoidal circular groove.

[0013] Preferably, the waterwheel includes an axle and several scrapers fixedly installed on the outer wall of the axle.

[0014] Preferably, the concealed pipe drainage system includes a concealed pipe and filter holes equidistantly opened on the outer periphery of the concealed pipe, and the outer wall of the concealed pipe is fixedly wrapped with a filter layer.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The rotation of the waterwheel will drive the scraper to clean the bottom surface of the inner cavity of the base, and at the same time carry the silt into the sedimentation tank. Then, only the sedimentation tank needs to be cleaned periodically. This achieves the effect of avoiding the accumulation of silt from affecting the water flow rate and damaging the channel structure.

[0017] 2. Use a T-hook to move the movable cover upwards, disengaging it from the through hole. Then, use a trawl cleaner to clean the sedimentation tank through the cleaning pipe. Finally, pull the T-hook to put the movable cover back into the through hole. This method improves safety and reduces maintenance workload. Attached Figure Description

[0023] 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.

[0024] Example 1: Please refer to Figures 2-4 A channel seepage prevention and protection device includes a base 1 and a cover plate 2 movably installed on the top surface of the base 1. The cover plate 2 serves to prevent potential safety accidents and prevent debris from entering the channel. A movable cover 3 is slidably embedded in the top surface of the cover plate 2. A cleaning pipe 4 is fixedly installed on the bottom surface of the cover plate 2. A cleaning structure 5 is rotatably installed in the inner cavity of the base 1. The cleaning structure 5 serves to clean the silt accumulated in the inner cavity of the base 1. A buried pipe drainage system 6 is fixedly installed through the bottom of the base 1. The buried pipe drainage system 6 serves to lower the groundwater level, reduce seepage pressure, and thus protect the seepage prevention layer from damage.

[0025] The top of the base 1 is covered with an impermeable layer 11. A sedimentation tank 12 is provided on the bottom surface of the inner cavity of the base 1. The sedimentation tank 12 serves to settle the silt in the channel. The groove of the sedimentation tank 12 corresponds to the opening of the cleaning pipe 4, so that the sedimentation tank 12 can be cleaned through the cleaning pipe 4. Trapezoidal grooves 13 are provided at both ends of the middle part of the base 1. A culvert 14 is provided through the bottom of the base 1. The culvert drainage system 6 is fixedly installed in the culvert 14.

[0026] The impermeable layer 11 includes a concrete layer 111 and a sand layer 112 laid on the bottom surface of the concrete layer 111. Geotextile 113 is laid on the bottom surface of the sand layer 112, and plastic film 114 is laid on the bottom surface of the geotextile 113.

[0027] The cleaning structure 5 includes a waterwheel 51 and limiting rings 52 that are movably installed on both sides of the waterwheel 51. The limiting rings 52 limit the main body of the waterwheel 51 and prevent the waterwheel 51 from moving laterally. A central shaft 53 is movably installed through the center of the waterwheel 51. The central shaft 53 limits and guides the waterwheel 51, allowing the waterwheel 51 to rotate on the central shaft 53. Protrusions 54 are fixedly installed on both sides of the central shaft 53 and are embedded in the inner cavity of the trapezoidal groove 13.

[0028] The waterwheel 51 includes an axle 511 and several scrapers 512 fixedly installed on the outer wall of the axle 511. The scrapers 512 serve to clean the mud and sand on the bottom surface of the inner cavity of the base 1.

[0029] The concealed pipe drainage system 6 includes a concealed pipe 61 and filter holes 62 equidistantly opened on the outer periphery of the concealed pipe 61. The outer wall of the concealed pipe 61 is fixedly wrapped with a water filter layer 63.

[0030] In this embodiment: During the process of water flowing from the top of the slope to the bottom of the slope of the base 1, some mud and sand will be retained at the bottom of the slope. However, at this time, the water flow will drive the waterwheel 51 to rotate. Then, the scraper 512 will clean the bottom surface of the inner cavity of the base 1 and carry the mud and sand into the sedimentation tank 12. Subsequently, the mud and sand will settle in the sedimentation tank 12. After that, it is only necessary to clean the sedimentation tank 12 periodically. This solves the problem of the impact of mud and sand accumulation on the water flow rate and avoids its damage to the channel structure.

[0031] Example 2: This example is an improvement on Example 1. For details, please refer to [link / reference]. Figures 1-4 The cover plate 2 has a through hole 21, and the movable cover 3 is embedded and slids in the inner cavity of the through hole 21. The through hole 21 is connected to the cleaning pipe 4. The movable cover 3 allows the sedimentation tank 12 to be cleaned through the cleaning pipe 4 without opening the cover plate 2.

[0032] The movable cover 3 includes a movable plate 31 and lifting rings 32 fixedly installed on both sides of the top surface of the movable plate 31. The lifting rings 32 facilitate the staff to lift the movable cover 3 and open it.

[0033] In this embodiment: when it is necessary to clean the sediment in the sedimentation tank 12, the staff must first use a T-hook to connect with the lifting ring 32, and then lift the T-hook to move the movable cover 3 upwards so that it leaves the through hole 21. Then, the movable cover 3 is placed aside, and the sedimentation tank 12 is cleaned by a trawler through the cleaning pipe 4. After cleaning, the movable cover 3 is put back into the through hole 21 by lifting the T-hook. This can avoid potential safety accidents and prevent debris from entering the channel, keeping the channel clean and unobstructed.

[0034] Working principle: As the water flows from the top of the slope of the base 1 to the bottom, some mud and sand will remain at the bottom of the slope. At this time, the water flow will drive the waterwheel 51 to rotate. Then, the scraper 512 will clean the bottom surface of the inner cavity of the base 1 and carry the mud and sand into the sedimentation tank 12. The mud and sand will then settle in the sedimentation tank 12. When it is necessary to clean the mud and sand in the sedimentation tank 12, the staff must first use a T-hook to connect with the lifting ring 32, and then lift the T-hook to move the movable cover 3 upwards so that it leaves the through hole 21. Then, the movable cover 3 is placed aside, and then the trawler cleaner is used to clean the sedimentation tank 12 through the cleaning pipe 4. After cleaning, the movable cover 3 is put back into the through hole 21 by lifting the T-hook.
