Description

Technical Field

[0001] The utility model relates to the technical field of dam engineering, in particular to a drainage hole filtering device. Background Art

[0002] In the foundations of concrete dams, earth-rock dams, or at the bottom of the reservoir basins of pumped-storage power stations with full reservoir basin anti-seepage, drainage observation galleries are generally set up to meet the needs of draining seepage water from the dam body or reservoir basin, safety monitoring, and inspection by operation and maintenance personnel during the operation period. The galleries need to be well drained. Since there are suspended solids, sediments, and other large particle impurities in the water, filtering needs to be done well. However, as the service time prolongs, impurities are likely to accumulate on the surface of the filter net or filter machine. Such accumulation will not only reduce the filtering efficiency but also be very difficult to clean. If not cleaned in time, these impurities may also block the drainage holes of the dam gallery, leading to water accumulation problems and further threatening the safety of the project.

[0003] To eliminate this threat, we need a drainage hole filtering device that is convenient for timely cleaning. Summary of the Utility Model

Obviously, the drawings in the following description are only some embodiments of the present utility model. For those of ordinary skill in the art, other drawings can be obtained based on these drawings without creative efforts.

[0021] In order to make the above objects, features, and advantages of the present utility model more obvious and understandable, the following will describe in detail the specific embodiments of the present utility model with reference to the accompanying drawings of the specification.

[0022] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0023] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure, or characteristic that can be included in at least one implementation manner of the present utility model. The phrase "in one embodiment" that appears in different places in this specification does not necessarily refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0024] Example 1, referring to Figures 1 to 2 , which is the first embodiment of the present utility model. This embodiment provides a drainage hole filtering device, including an interception component 100, which includes a bottom plate 102, an outer interception member 104 provided on the top of the bottom plate 102, and an inner interception member 105 provided inside the outer interception member 104. The bottom plate 102 is fixedly arranged at the bottom of the corridor k. The interception component 100 intercepts impurities in the water in two stages through the outer interception member 104 and the inner interception member 105 to prevent the impurities from blocking the drainage hole k-1. And, a cleaning component 200, which includes an outer vibration member 205 and an alarm member provided inside the outer vibration member 205. The cleaning component 200 will clean the interception component 100 during drainage, but over time, it will still cause blockage to the interception component 100. Since the drainage outlet of the corridor is at the bottom, it is not easy to detect the blockage in time. The alarm member will alarm when the interception component 100 is blocked, reminding the staff to clean it in time.

[0025] Furthermore, a sealing ring 101 is provided at the bottom of the bottom plate 102, and a water inlet hole 103 is opened in the middle part of the bottom plate 102. The water inlet hole 103 is communicated with the drainage hole k-1. The water filtered by the interception component 100 is discharged into the drainage hole k-1 through the water inlet hole 103.

[0026] During operation: The interception component 100 intercepts impurities in water in two stages through the outer interception member 104 and the inner interception member 105 to prevent the impurities from blocking the drain hole k-1. The cleaning component 200 will clean the interception component 100 during drainage, but over time, it will still cause blockage to the interception component 100. Since the corridor drain outlet is at the bottom, it is not easy to detect the blockage in time. The alarm component will alarm when the interception component 100 is blocked to remind the staff to clean it in time.

[0027] Embodiment 2, refer to Figures 1 to 3 , which is the second embodiment of the present invention. Different from the previous embodiment, the outer interception member 104 includes an outer interception net 104a, and sieve holes 104b are formed on the outer wall of the outer interception net 104a. The inner interception member 105 includes an inner interception net 105a, and filter holes 105b are formed on the outer wall of the inner interception net 105a. The aperture of the sieve holes 104b is larger than that of the filter holes 105b. The sieve holes 104b of the outer interception net 104a first intercept large-particle impurities in the water body, and the filter holes 105b of the inner interception net 105a then intercept smaller-particle impurities.

[0028] Furthermore, a bracket 201 is provided at the top of the outer interception net 104a. A central rod 202 is provided on the inner wall of the bracket 201. A connecting frame 203 is provided on the outer wall of the central rod 202. An impeller 204 is provided at the bottom of the central rod 202. When the water flow intercepted by the outer interception net 104a and the inner interception net 105a drains from the water inlet hole 103 into the drain hole k-1, the water flow will drive the impeller 204 to rotate, and the impeller 204 will drive the central rod 202 to rotate.

[0029] Furthermore, the outer vibration member 205 includes an upper curved rod 205a provided on the outer wall of the central rod 202. A first hammer 205b is provided at one end of the upper curved rod 205a away from the central rod 202. The first hammer 205b is in contact with the outer interception net 104a. The outer interception net 104a is arranged in a waveform. When the water flow drains from the water inlet hole 103 into the drain hole k-1, the rotation of the central rod 202 will drive the upper curved rod 205a to rotate and drive the first hammer 205b to strike the outer interception net 104a. Thus, the outer interception net 104a will vibrate, shaking off the impurities intercepted and retained on the outer interception net 104a, cleaning the interception net while filtering.

[0030] Further, an inner vibration member 206 is provided inside the inner retaining net 105a. The inner vibration member 206 includes a lower curved bar 206a disposed on the outer wall of the central rod 202. A second hammer 206b is provided at one end of the lower curved bar 206a away from the central rod 202. The second hammer 206b is in contact with the inner retaining net 105a. The inner retaining net 105a is arranged in a waveform. When water flows from the water inlet hole 103 into the drain hole k-1, the rotation of the central rod 202 will drive the lower curved bar 206a to rotate, driving the second hammer 206b to strike the inner retaining net 105a. Thus, the inner retaining net 105a will vibrate, shaking off the impurities intercepted and retained on the inner retaining net 105a, cleaning the retaining net while filtering.

[0031] Usage process: When water flows through the interception assembly 100, the sieve holes 104b of the outer retaining net 104a first intercept large-particle impurities in the water body, and the filter holes 105b of the inner retaining net 105a then intercept smaller-particle impurities. When water flows from the water inlet hole 103 into the drain hole k-1, the rotation of the central rod 202 will drive the upper curved bar 205a to rotate, driving the first hammer 205b to strike the outer retaining net 104a. Thus, the outer retaining net 104a will vibrate, shaking off the impurities intercepted and retained on the outer retaining net 104a. At the same time, the rotation of the central rod 202 will drive the lower curved bar 206a to rotate, driving the second hammer 206b to strike the inner retaining net 105a. Thus, the inner retaining net 105a will vibrate, shaking off the impurities intercepted and retained on the inner retaining net 105a, cleaning the retaining net while filtering.

[0032] Example 3, referring to Figures 1 to 3 , which is the third embodiment of the present utility model. Different from the previous embodiment, the alarm member includes a wheel disc 207a disposed on the outer wall of the central rod 202. A hollow cylinder 207b is provided on the outer wall of the wheel disc 207a. A connecting rod 207c is provided at the bottom of the wheel disc 207a. A floating tube 207d is provided at the bottom of the connecting rod 207c. A support rod 207e is provided on the inner wall of the floating tube 207d. The bottom of the support rod 207e is connected to the bottom plate 102. The support rod 207e is fixed on the bottom plate 102. A sliding hole is provided on the floating tube 207d passing through the support rod 207e. The floating tube 207d can slide on the outer wall of the support rod 207e. When the interception assembly 100 is used for a period of time, a lot of impurities will remain on the retaining net, and the filtering effect will decline. Thus, water will be retained between the outer retaining net 104a and the inner retaining net 105a, causing the water level to rise, driving the floating tube 207d to rise. The floating tube 207d will drive the wheel disc 207a to rise through the connecting rod 207c until the hollow cylinder 207b on the side of the wheel disc 207a contacts the upper curved bar 205a. At this time, the rotation of the central rod 202 will drive the upper curved bar 205a to rotate and collide with the hollow cylinder 207b, making a sound, which will remind the staff that the interception assembly 100 needs to be cleaned to ensure timely cleaning of the interception assembly 100.

[0033] Usage process: When the interception component 100 has been used for a period of time, a lot of impurities will remain on the interception net, and the filtering effect will decline. As a result, water will be retained between the outer interception net 104a and the inner interception net 105a, causing the water level to rise, driving the floating pipe 207d to rise. The floating pipe 207d will drive the wheel disc 207a to rise through the connecting rod 207c until the hollow cylinder 207b on the side of the wheel disc 207a contacts the upper curved rod 205a. At this time, when the central rod 202 rotates, it will drive the upper curved rod 205a to rotate and collide with the hollow cylinder 207b, making a sound, which will remind the staff that the interception component 100 needs to be cleaned to ensure that the interception component 100 is cleaned in time.
