Description

Technical Field

[0001] The utility model belongs to the technical field of slope drainage, and in particular relates to a self-cleaning yard slope drainage structure. Background Art

[0002] A storage yard refers to a specific area within a construction site, which is used specifically for storing various construction materials such as steel bars, cement, bricks, steel, wood, etc. that are needed in construction production. The storage yard is an important place in the construction process. In order to prevent the storage yard from collapsing due to water accumulation, a drainage structure needs to be set up on the slope of the storage yard.

[0003] A Chinese patent with publication number CN220336048U discloses a drainage structure for a yard slope, which includes a drainage pipe, a scraper mechanism and a clamping mechanism. A filter screen is provided in the drainage pipe through the clamping mechanism, and the scraper mechanism includes hydraulic fan blades. The above scheme utilizes the water flow during drainage as power to drive the hydraulic fan blades to rotate, thereby scraping off the blocked mud and sand on the surface of the filter screen, reducing the frequency of manual intervention to clean the filter screen.

[0004] When the above scheme is in use, the projection of the working area covered by the rotating hydraulic fan blades is circular, resulting in the above scheme being unable to clean the corners of the rectangular filter screen plate, easily resulting in cleaning dead corners, and thus resulting in poor drainage effect of the above scheme. Utility Model Content

[0005] The utility model aims to provide a self-cleaning yard slope drainage structure to solve the problem of prone to cleaning dead corners in the above-mentioned method.

[0006] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0007] A self-cleaning yard slope drainage structure includes a drainage pipe, a scraper mechanism and a locking mechanism, a sieve plate is slidably inserted in the drainage pipe, a rotating shaft is rotatably penetrated through the bottom wall of the drainage pipe, and a plurality of hydraulic fan blades are arranged at intervals along the circumference above the bottom wall of the drainage pipe outside the rotating shaft, the scraper mechanism includes a scraper and a pull rope, the scraper is slidably arranged in the drainage pipe, and the scraper and the sieve plate are slidably abutted, one end of the pull rope is fixedly connected to the bottom of the scraper, the other end of the pull rope is slidably penetrated through the bottom wall of the drainage pipe, and is wound around the rotating shaft below the bottom wall of the drainage pipe, and the other end of the pull rope is fixedly connected to the side wall of the rotating shaft, and the locking mechanism is arranged on the front and rear sides of the drainage pipe and connected to the sieve plate.

[0008] The principle and effect of this technical solution:

[0009] The sieve plate is slidably inserted into the top of the drain pipe, and the movement of the sieve plate is restricted by a locking mechanism. After the water flow on the surface of the yard is introduced into the drain pipe, the water flow flushes the hydraulic fan blades, thereby driving the rotating shaft to rotate and tightening the pull rope on the rotating shaft. The pull rope pulls the scraper to move toward the bottom wall of the drain pipe. Since the scraper and the sieve plate are in sliding contact, the mud and sand attached to the sieve plate are swept off during the movement of the scraper to clean the sieve plate. When the scraper touches the bottom, the water flow cannot continue to drive the hydraulic fan blades to rotate due to the restriction of the pull rope.

[0010] Through the above arrangement, water flow is used to drive the hydraulic fan blades and the rotating shaft to rotate, and then the pull rope is tightened to drive the scraper to move along the screen plate, so that the working area of ​​the scraper covers the entire screen plate, thereby solving the problem of dead corners in cleaning in the above solution and improving drainage efficiency.

[0011] In the utility model, a guide rod is fixedly arranged in the drainage pipe in a direction parallel to the screen plate, a scraper is slidably sleeved on the guide rod, and a tension spring is arranged outside the guide rod between the scraper and the top wall of the drainage pipe.

[0012] The principle and effect of this technical solution:

[0013] When the water flow drives the hydraulic fan blades and the rotating shaft to rotate, and then tightens the pull rope to drive the scraper to move along the screen plate, the scraper stretches the tension spring to make it elastic. When all the accumulated water on the surface of the yard flows out through the drain pipe, the hydraulic fan blades lose the force applied by the water flow. The elastic force of the tension spring is greater than the sum of the gravity of the scraper and the friction between the scraper and the screen plate, thereby pulling the scraper to reset. At the same time, through the pull rope, the rotating shaft rotates in the opposite direction until the scraper touches the top of the drain pipe.

[0014] Through the above arrangement, after the scraper completes a cleaning work, it can automatically reset and complete the cleaning work again, which improves the cleaning effect and the practicality of the utility model.

[0015] In the utility model, a horizontal plate is fixedly arranged at the bottom of the sieve plate on the left side of the sieve plate along a direction perpendicular to the sieve plate.

[0016] In the utility model, the bottom wall of the drainage pipe is provided with a groove matched with the horizontal plate.

[0017] In the utility model, an opening is arranged at the top of the drainage pipe at the horizontal plate, and a shielding plate cooperating with the opening is fixedly arranged at the top of the sieve plate.

[0018] In the utility model, a handle is fixedly provided on the top of the shield.

[0019] The principle and effect of this technical solution:

[0020] In the initial state, the horizontal plate is embedded in the groove, and the top of the horizontal plate is flush with the bottom wall of the drain pipe. When larger debris flows into the drain pipe with the water flow, this part of the debris will flow from above the horizontal plate to the screen plate, and the screen plate will prevent it from moving forward. When the water flow slows down, this part of the debris will fall freely to the top of the horizontal plate due to gravity. The maintenance personnel use the handle to lift the screen plate and the horizontal plate out of the opening and remove this part of the debris. After completing the cleaning work, the screen plate and the horizontal plate are reset to connect the locking mechanism to the screen plate. At this time, the shield on the top of the screen plate covers the opening.

[0021] Through the above arrangement, it is convenient for maintenance personnel to clean up the debris intercepted by the screen plate, thereby improving work efficiency. At the same time, the opening can be shielded to prevent water from flowing out of the opening, thereby improving the practicality of the utility model.

[0022] In the utility model, the locking mechanism includes a slide groove recessed in the inner walls of the front and rear sides of the drain pipe, a limit block slidably embedded in the slide groove, a lever fixedly arranged on the side wall of the limit block and slidably penetrated through the side wall of the drain pipe, a compression spring sleeved on the outside of the lever between the end wall of the slide groove and the limit block, and a limit groove recessed in the side wall of the screen plate and cooperating with the limit block.

[0023] In the utility model, a guide inclined surface is arranged on the top of the limit block close to one end of the sieve plate.

[0024] The principle and effect of this technical solution:

[0025] Before sliding out the sieve plate, pull the lever to disengage the limit block from the limit groove. At this time, the sieve plate can slide outward. When resetting the sieve plate, slide the sieve plate inward, the sieve plate abuts against the guide inclined surface, and pushes the limit block to move into the slide groove while compressing the compression spring. When the sieve plate is reset, the lower edge of the limit groove is lower than the lower edge of the limit block, and the compression spring pushes the limit block to move into the limit groove.

[0026] Through the above arrangement, the upward displacement of the sieve plate can be limited to prevent the sieve plate from detaching from the drain pipe due to the impact of water flow. At the same time, after the sieve plate is taken out, it is convenient for maintenance personnel to install the sieve plate without having to pull the lever again, thereby improving installation efficiency.

[0027] In the utility model, the cross section of the hydraulic fan blade is arranged to be arc-shaped. Through the above arrangement, the hydraulic fan blade can rotate along a fixed direction when impacted by water flow.

[0028] In the utility model, the outer walls of the front and rear sides of the drainage pipe are respectively fixed with connecting plates, and the two connecting plates are respectively slidably penetrated with anchor rods. Through the above arrangement, the utility model can be fixed on the surface of the yard slope, improving the stability of the utility model when in use. BRIEF DESCRIPTION OF THE DRAWINGS

[0036] Example:

[0037] As attached Figure 1-5 As shown, the utility model discloses a self-cleaning yard slope drainage structure, including a drainage pipe 10, a scraping mechanism and a locking mechanism, wherein a sieve plate 20 is slidably inserted in the drainage pipe 10, and sliding grooves are arranged on the inner walls of the front and rear sides of the drainage pipe 10, and the front and rear ends of the sieve plate 20 are respectively slidably embedded in the sliding grooves, and a rotating shaft 11 is rotatably penetrated through the bottom wall of the drainage pipe 10, and a plurality of hydraulic fan blades 111 are arranged at intervals along the circumference of the rotating shaft 11 above the bottom wall of the drainage pipe 10, and the scraping mechanism is provided on the inner walls of the drainage pipe 10. The material mechanism includes a scraper 31 and a pull rope 32. The scraper 31 is slidably arranged in the drain pipe 10, and the scraper 31 is slidably abutted against the sieve plate 20. One end of the pull rope 32 is fixedly connected to the bottom of the scraper 31, and the other end of the pull rope 32 is slidably passed through the bottom wall of the drain pipe 10, and is wound around the rotating shaft 11 below the bottom wall of the drain pipe 10, and the other end of the pull rope 32 is fixedly connected to the side wall of the rotating shaft 11. The locking mechanism is arranged on the front and rear sides of the drain pipe 10 and is connected to the sieve plate 20.

[0038] In this embodiment, a guide rod 12 is fixedly provided in the drain pipe 10 in a direction parallel to the screen plate 20 , the scraper 31 is slidably sleeved on the guide rod 12 , and a tension spring 13 is provided outside the guide rod 12 between the scraper 31 and the top wall of the drain pipe 10 .

[0039] In this embodiment, a horizontal plate 21 is fixedly provided at the bottom of the sieve plate 20 and at the left side of the sieve plate 20 along a direction perpendicular to the sieve plate 20 .

[0040] In this embodiment, the bottom wall of the drain pipe 10 is recessed with a groove 16 that matches with the horizontal plate 21 .

[0041] In this embodiment, an opening 14 is provided at the top of the drain pipe 10 at the transverse plate 21 , and a shielding plate 22 cooperating with the opening 14 is fixedly provided at the top of the sieve plate 20 .

[0042] In this embodiment, a handle 221 is fixedly provided on the top of the shield 22 .

[0043] In this embodiment, the locking mechanism includes a slide groove 41 recessed in the inner walls of the front and rear sides of the drain pipe 10, a limit block 42 slidably embedded in the slide groove 41, a lever 43 fixedly arranged on the side wall of the limit block 42 and slidably penetrated through the side wall of the drain pipe 10, a compression spring 44 sleeved on the outside of the lever 43 between the end wall of the slide groove 41 and the limit block 42, and a limit groove 45 recessed in the side wall of the screen plate 20 and cooperating with the limit block 42.

[0044] In this embodiment, a guide inclined surface 421 is provided at the top of the limiting block 42 close to one end of the sieve plate 20 .

[0045] In this embodiment, the cross section of the hydraulic fan blade 111 is arranged to be arc-shaped.

[0046] In this embodiment, connecting plates 15 are fixedly provided on the front and rear outer walls of the drainage pipe 10 , and anchor rods 151 are slidably penetrated through the two connecting plates 15 .

[0047] The specific implementation process is as follows:

[0048] The sieve plate 20 is slidably inserted into the top of the drain pipe 10, and the movement of the sieve plate 20 is limited by the locking mechanism. After the water flow on the surface of the yard is introduced into the drain pipe 10, the water flow flushes the hydraulic fan blades 111, thereby driving the rotating shaft 11 to rotate, and the rotating shaft 11 tightens the pull rope 32. The pull rope 32 pulls the scraper 31 to move toward the bottom wall of the drain pipe 10. Since the scraper 31 slides and abuts against the sieve plate 20, the scraper 31 sweeps off the mud and sand attached to the sieve plate 20 during its movement, and cleans the sieve plate 20. When the scraper 31 touches the bottom, it is restricted by the pull rope 32, and the water flow cannot continue to drive the hydraulic fan blades 111 to rotate.

[0049] When the water flow drives the hydraulic fan blades 111 and the rotating shaft 11 to rotate, and then tightens the pull rope 32 to drive the scraper 31 to move along the sieve plate 20, the scraper 31 stretches the tension spring 13 to make it elastic. When all the accumulated water on the surface of the yard flows out through the drain pipe 10, the hydraulic fan blades 111 lose the force applied by the water flow. The elastic force of the tension spring 13 is greater than the sum of the gravity of the scraper 31 and the friction between the scraper 31 and the sieve plate 20, thereby pulling the scraper 31 to reset. At the same time, through the pull rope 32, the rotating shaft 11 is rotated in the reverse direction until the scraper 31 abuts against the top of the drain pipe 10.

[0050] In the initial state, the transverse plate 21 is embedded in the groove 16, and the top of the transverse plate 21 is flush with the bottom wall of the drain pipe 10. When larger debris flows into the drain pipe 10 with the water flow, this part of the debris will flow from above the transverse plate 21 to the sieve plate 20, and the sieve plate 20 will prevent it from moving forward. When the water flow slows down, this part of the debris will fall freely to the top of the transverse plate 21 due to gravity. The maintenance personnel use the handle 221 to lift the sieve plate 20 and the transverse plate 21 out of the opening 14 and remove this part of the debris. After completing the cleaning work, the sieve plate 20 and the transverse plate 21 are reset to connect the locking mechanism to the sieve plate 20. At this time, the shield 22 on the top of the sieve plate 20 covers the opening 14.

[0051] Before sliding out the sieve plate 20, pull the lever 43 to disengage the limit block 42 from the limit groove 45. At this time, the sieve plate 20 can slide outward. When the sieve plate 20 is reset, slide the sieve plate 20 inward, the sieve plate 20 abuts against the guide slope 421, and pushes the limit block 42 to move into the slide groove 41 while compressing the compression spring 44. When the sieve plate 20 is reset, the lower edge of the limit groove 45 is lower than the lower edge of the limit block 42, and the compression spring 44 pushes the limit block 42 to move into the limit groove 45.

[0052] The above is only an embodiment of the utility model, and the common knowledge such as the known specific technical scheme or characteristics in the scheme is not described in detail here. It should be pointed out that for those skilled in the art, several deformations and improvements can be made without departing from the technical scheme of the utility model, which should also be regarded as the protection scope of the utility model, and these will not affect the effect of the implementation of the utility model and the practicality of the patent. The scope of protection required by this application shall be based on the content of its claims, and the specific implementation methods and other records in the specification can be used to interpret the content of the claims.
