Description

Technical Field

[0001] This invention relates to the field of water conservancy waterproofing and drainage devices, and more specifically, to a waterproofing and drainage device and method suitable for water conservancy construction. Background Technology

[0002] Waterproofing and drainage are crucial in water conservancy construction. A reasonable waterproofing and drainage plan can improve the bearing capacity of the foundation, prevent slope instability, and ensure the smooth progress of the project and the quality of construction.

[0003] Patent application number CN202222624975.4 discloses a waterproof drainage device for hydraulic construction, including a box and a drain pipe. A drain pipe fixed to the box is installed through the top of the box, and an upper filter screen is fixed to the inner wall of the drain pipe. A brushing component for cleaning the upper filter screen is provided inside the box, and a power component that moves with the water flow and drives a vertical rod to rotate is also provided inside the box. Rainwater flows down from the drain pipe, and the water flows through the mesh of the upper filter screen. The power component moves with the water flow and drives the vertical rod to rotate, thereby causing the cleaning brush fixed to the vertical rod to rotate, so that the bristles of the cleaning brush clean the mesh of the upper filter screen.

[0004] However, traditional equipment lacks water level sensing and automatic triggering mechanisms, requiring manual regular inspection and cleaning of filter screens and silt. During construction, silt accumulation can cause a sudden drop in drainage speed, and manual intervention is delayed, making it difficult to maintain efficient drainage in real time. In addition, existing equipment mostly uses fixed filters and independent flushing components, requiring the machine to be stopped to disassemble the filter screen or flush the pipeline during silt removal, which is cumbersome and the components are easily damaged.

[0005] In view of this, we propose a waterproof drainage device and method suitable for water conservancy construction. Summary of the Invention

[0006] The purpose of this invention is to provide a waterproof drainage device and method suitable for water conservancy construction, so as to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, the present invention provides the following technical solution: A waterproof drainage device suitable for water conservancy construction includes a water inlet tank, an actuating device installed inside the water inlet tank, a buoyancy mechanism that rises with the water level, and a flushing mechanism installed below the water inlet tank. The water inlet tank includes a tank body located in the upper half, a rotating ring located below the drain pipe on the bottom surface of the tank body, and two drain pipes located at the bottom of the rotating ring for draining water and sewage respectively. A filter screen is attached above the drain pipe opening. Four water passage holes are opened on the top surface of the rotating ring, and the two drain pipes are coaxially arranged with the two adjacent water passage holes. The actuating device includes a rotating part, spools on both sides of the rotating part, a spiral spring inside the spools, a ratchet that rotates with the spools, and a connecting rope wound around the outside of the spools. When the water level rises, the end of the connecting rope moves up with the buoyancy mechanism. When it reaches the highest water level, the end of the connecting rope separates from the buoyancy mechanism, and the spring force of the spiral spring drives the spools to rotate. The ratchet then drives the rotating part to rotate, which in turn drives the rotating ring to rotate 90°. Every 90° rotation of the rotating ring scrapes the silt on the filter screen into the sewage discharge pipe. The flushing mechanism includes a round plug, an outer sleeve fitted on the outside of the round plug, and a nozzle located at the end of the outer sleeve. The round plug has a through-hole that runs from left to right. The round plug moves up and down as the rotating part rotates, allowing the flushing fluid to clean the sludge adhering to the inner wall of the through-hole.

[0008] In the technical solution of the present invention, the water inlet tank further includes a limiting ring welded to its bottom surface, a partition welded to the outside of the bottom end of the drain pipe, two outer brackets snapped onto the bottom surface of the partition, round rods snapped onto the inner corners of the tank body, and a grille placed at the top opening of the tank body.

[0009] In the technical solution of the present invention, the rotating ring is rotatably connected to the top surface of the limiting ring, the four water passage holes are distributed in a matrix, and the bottom of the outer ring wall of the rotating ring is fixed with ring teeth.

[0010] In the technical solution of the present invention, the rotating part includes a rotating shaft, a worm gear and shaft teeth that are snapped onto the outer wall of the rotating shaft, an outer ring that is fixedly connected to the end of the rotating shaft by bolts, and a plurality of pawls that are rotatably connected to the inner wall of the outer ring. The outer ring is rotatably connected to the inside of the outer frame.

[0011] In the technical solution of the present invention, a fixing rod is provided inside the reel, and the outer end of the fixing rod is snapped and fixed to the inner wall of the housing. The inner end of the spiral spring is snapped to the outer wall of the fixing rod, and the outer end is snapped and fixed to the inner wall of the reel.

[0012] In the technical solution of the present invention, the ratchet is fixed to the outer wall of the spool by a central shaft, and the end of the connecting rope extends into the interior of the box and is attached to a connecting block.

[0013] In the technical solution of the present invention, the floating mechanism includes two symmetrically arranged sliders slidably connected inside the round rod, two symmetrically distributed bent plates rotatably connected inside the sliders, a plurality of first springs arranged between the two bent plates, and a float plate snapped between the two sliders. The two ends of the first spring are respectively attached to the outer walls of the two bent plates, and the first spring is provided with a limiting telescopic rod that restricts its extension range. The water inlet tank also includes two sets of guide blocks arranged above the bent plates and welded to the inner wall of the tank. When the top of the bent plate contacts the bottom surface of the guide block, it will bend inward.

[0014] In the technical solution of the present invention, the flushing mechanism further includes a lower pressure frame snapped onto the bottom surface of the round plug and a second spring sleeved on the outside of the round plug. The bottom surface of the lower pressure frame is integrally formed with a trapezoidal protrusion that abuts against the shaft teeth. The upper and lower ends of the second spring are respectively bonded and fixed to the top surface of the lower pressure frame and the bottom surface of the partition.

[0015] In the technical solution of the present invention, the longitudinal section of the outer sleeve is cross-shaped, the round plug is slidably connected to the inside of the longitudinal tube of the outer sleeve, and the nozzle is snapped and fixed to the top surface of the partition.

[0016] On the other hand, the present invention also provides a waterproofing and drainage method suitable for water conservancy construction, which, using the above-mentioned waterproofing and drainage equipment suitable for water conservancy construction, includes the following steps: S1. Water flows into the interior of the tank through the grille at the top of the inlet tank, and then through the drain pipe at the bottom of the tank, passing through the water passage on the rotating ring, and flowing into the interior of the drain pipe. The silt and dirt in the water will be filtered by the filter screen on the drain pipe. S2. When the silt on the filter screen of the drain pipe accumulates excessively, it affects the flow rate of water. After the blockage occurs, the water level in the inlet tank will rise, causing the float plate to drive the entire floating mechanism to move upward together. S3. At this time, the two sets of bending plates clamp the two docking blocks respectively and pull the two connecting ropes, thereby driving the spool to rotate in the same direction and continuously increasing the elastic potential energy of the internal spiral spring. S4. When the top of the bending plate comes into contact with the guide block, the tops of the symmetrically arranged bending plates bend towards each other, causing the bottom protrusion to loosen the connecting block, thereby causing the spring force of the spiral spring to drive the spool to rotate in the opposite direction, thus causing the ratchet to rotate in the opposite direction inside the outer ring. S5. After the ratchet comes into contact with several pawls, it drives the outer ring to rotate in the opposite direction, causing the shaft to rotate, which in turn causes the worm and shaft teeth on the shaft to rotate simultaneously. S6. After the worm rotates, it drives the rotating ring to rotate through contact with the ring teeth, which scrapes the sludge above the filter screen into the drain pipe used for sewage discharge, thereby allowing water to flow quickly through the drain pipe used for drainage. S7. After the shaft gear rotates, it will continuously move the trapezoidal protrusion under the lower pressure frame. Under the elastic force of the second spring, the lower pressure frame will move up and down repeatedly. After the round plug moves up and down repeatedly, the flushing water will periodically flush the inside of the water passage hole, thus washing away the sludge attached to the inner wall of the water passage hole.

[0017] Compared with the prior art, the beneficial effects of the present invention are: 1. The waterproof drainage equipment and method applicable to water conservancy construction, when the water level inside the tank rises, the rotating part in the actuating device is activated by the floating mechanism to rotate, thereby driving the rotating ring to clean the silt above the filter screen of the drain pipe. This avoids the need for traditional equipment to rely on manual periodic cleaning and mechanical equipment filtration, while ensuring continuous and efficient drainage.

[0018] 2. The waterproof drainage equipment and method applicable to water conservancy construction, when the rotating part rotates as a whole, will drive the round plug in the flushing mechanism to move up and down, so that the flushing water can automatically flush the inner wall of the water passage hole when the rotating ring rotates, thereby simplifying the process of rinsing and cleaning the filter screen.

[0020] The technical solutions of this invention will now be clearly and completely described with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this invention, and not all of them. All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0021] See also Figures 1-10 As shown, this embodiment provides a technical solution: A waterproof drainage device suitable for water conservancy construction includes a water inlet tank 100, an actuating device 200 disposed inside the water inlet tank 100, a buoyancy mechanism 300 that rises with the water level, and a flushing mechanism 400 disposed below the water inlet tank 100. In this embodiment, as Figures 3-4 As shown, the water inlet tank 100 includes a tank body 110 located in the upper part, a rotating ring 140 located below the drain pipe on the bottom surface of the tank body 110, and two drain pipes 160 located at the bottom of the rotating ring 140 for draining water and sewage respectively. A filter screen is attached above the drain pipe opening. The top surface of the rotating ring 140 has four water passage holes 141. The two drain pipes 160 are coaxially arranged with the two adjacent water passage holes 141.

[0022] Specifically, the water inlet tank 100 also includes a limiting ring 120 welded to its bottom surface, a partition 130 welded to the outside of the bottom end of the drain pipe, two outer brackets 150 snapped onto the bottom surface of the partition 130, round rods 180 snapped onto the inner corners of the tank body 110, and a grille 190 placed at the top opening of the tank body 110.

[0023] Furthermore, the rotating ring 140 is rotatably connected to the top surface of the limiting ring 120, and the four water passage holes 141 are distributed in a matrix. The bottom of the outer ring wall of the rotating ring 140 is fixed with ring teeth 142.

[0024] Furthermore, the housing 110 is used to ensure the overall structural strength of the water inlet tank 100, the limiting ring 120, together with the partition 130, is used to increase the rotation range of the rotating ring 140, the outer frame 150 is used to increase the rotation range of the internal structure of the actuating device 200, the round rod 180 is used to limit the movement range of the floating mechanism 300, and the grille 190 is used to prevent larger dirt from entering the interior of the water inlet tank 100.

[0025] In this embodiment, as Figures 5-8 As shown, the actuating device 200 includes a rotating part 210, reels 220 disposed on both sides of the rotating part 210, a spiral spring 240 disposed inside the reel 220, a ratchet 250 that rotates together with the reel 220, and a connecting rope 260 wound around the outside of the reel 220. When the water level rises, the end of the connecting rope 260 moves upward together with the buoyancy mechanism 300. When it moves to the highest water level, the end of the connecting rope 260 separates from the buoyancy mechanism 300, and the elastic force of the spiral spring 240 drives the reel 220 to rotate. The ratchet 250 drives the rotating part 210 to rotate, which in turn drives the rotating ring 140 to rotate 90°. Every time the rotating ring 140 rotates 90°, it scrapes the silt on the filter screen into the sewage discharge pipe 160.

[0026] Specifically, the rotating part 210 includes a rotating shaft 211, a worm gear 212 and a shaft tooth 213 that are engaged on the outer wall of the rotating shaft 211, an outer ring 214 that is fixedly connected to the end of the rotating shaft 211 by bolts, and a number of pawls 215 that are rotatably connected to the inner ring wall of the outer ring 214. The outer ring 214 is rotatably connected to the inside of the outer frame 150.

[0027] Furthermore, a fixing rod 230 is provided inside the reel 220. The outer end of the fixing rod 230 is snapped and fixed to the inner wall of the housing 110. The inner end of the spiral spring 240 is snapped to the outer wall of the fixing rod 230 and the outer end is snapped and fixed to the inner wall of the reel 220.

[0028] Furthermore, the ratchet 250 is fixed to the outer wall of the spool 220 by a central shaft, and the end of the connecting rope 260 extends into the interior of the housing 110 and is attached to the end with a connecting block 270.

[0029] Furthermore, as the water level in the inlet tank 100 rises, the buoyancy mechanism 300 moves upward with the water level, causing the ends of the two connecting ropes 260 to rise together. This causes the reel 220 to rotate clockwise, continuously increasing the elastic potential energy of the internal spiral spring 240. When the ends of the connecting ropes 260 separate from the buoyancy mechanism 300, the elastic force of the spiral spring 240 causes the reel 220 to rotate counterclockwise, causing the ratchet 250 to rotate counterclockwise inside the outer ring 214. After the ratchet 250 contacts several pawls 215, it causes the outer ring 214 to rotate counterclockwise, causing the shaft 211 to rotate. This, in turn, causes the worm gear 212 and the shaft tooth 213 on the shaft 211 to rotate simultaneously.

[0030] Furthermore, when the spiral spring 240 returns to its initial state, the rotating worm 212 will contact the ring tooth 142, causing the rotating ring 140 to rotate 90°, scraping the sludge above the filter screen into the drain pipe 160 for sewage discharge, thereby allowing water to flow quickly through the drain pipe 160 for drainage.

[0031] In this embodiment, as Figure 9 As shown, the floating mechanism 300 includes two symmetrically arranged sliders 310 slidably connected inside the round rod 180, two symmetrically distributed bent plates 320 rotatably connected inside the sliders 310, several first springs 330 arranged between the two bent plates 320, and a float plate 340 snapped between the two sliders 310. The two ends of the first springs 330 are respectively attached to the outer walls of the two bent plates 320, and the first springs 330 are provided with limiting telescopic rods that limit their extension range. The water inlet tank 100 also includes two sets of guide blocks 170 arranged above the bent plates 320 and welded to the inner wall of the tank body 110. When the top of the bent plate 320 contacts the bottom surface of the guide block 170, it will bend inward.

[0032] Furthermore, after the water level in the inlet tank 100 rises, the float 340 will drive the entire buoyancy mechanism 300 to move upwards together. At this time, the bottom ends of the two bent plates 320 will engage with the protrusion on the top of the connecting block 270. As the two bent plates 320 rise with the slider 310, they will drive the connecting block 270 to move upwards together. The connecting rope 260 will pull the reel 220 to rotate. When the top of the bent plate 320 abuts against the guide block 170, it will... The tops of the bent plates 320 bend towards each other, causing the bottom protrusions to loosen from the connecting block 270. This allows the spring force of the spiral spring 240 to drive the reel 220 to rotate in the opposite direction. When the water level drops, the buoyancy mechanism 300 will reset under its own weight. The bottoms of the two bent plates 320 bend after contacting the connecting block 270. Then, under the action of the spring force of the first spring 330, the bottoms of the two bent plates 320 are re-engaged on the outside of the top protrusion of the connecting block 270.

[0033] In this embodiment, as Figure 10 As shown, the flushing mechanism 400 includes a plug 420, an outer sleeve 440 sleeved on the outside of the plug 420, and a nozzle 450 disposed at the end of the outer sleeve 440. The plug 420 has a through-hole 421 that runs from left to right. The plug 420 moves up and down with the rotation of the rotating part 210, allowing the flushing fluid to clean the sludge attached to the inner wall of the through-hole 141. The other end of the outer sleeve 440 is connected to an external water pump.

[0034] Specifically, the flushing mechanism 400 also includes a lower pressure frame 410 that is snapped onto the bottom surface of the round plug 420 and a second spring 430 that is sleeved on the outside of the round plug 420. The bottom surface of the lower pressure frame 410 is integrally formed with a trapezoidal protrusion that abuts against the shaft tooth 213. The upper and lower ends of the second spring 430 are respectively bonded and fixed to the top surface of the lower pressure frame 410 and the bottom surface of the partition 130.

[0035] Furthermore, the longitudinal section of the outer sleeve 440 is cross-shaped, the round plug 420 is slidably connected to the inside of the longitudinal tube of the outer sleeve 440, and the nozzle 450 is snapped and fixed to the top surface of the partition 130.

[0036] Furthermore, after the shaft tooth 213 rotates, it will continuously actuate the trapezoidal protrusion below the lower pressure frame 410. Under the elastic force of the second spring 430, the lower pressure frame 410 will move up and down repeatedly. After the round plug 420 moves up and down repeatedly, the flushing water will periodically flush the inside of the water passage hole 141, thus flushing away the sludge attached to the inner wall of the water passage hole 141. When the shaft tooth 213 stops rotating, the position of the lower pressure frame 410 will also return to its original position, thus stopping the entry of the flushing liquid.

[0037] This invention also provides a waterproofing and drainage method suitable for water conservancy construction. Using the aforementioned waterproofing and drainage equipment suitable for water conservancy construction, the method includes the following steps: S1. Water flows into the interior of the tank 110 through the grille 190 at the top of the inlet tank 100, and through the drain pipe at the bottom of the tank, through the water passage hole 141 on the rotating ring 140, and into the interior of the drain pipe 160. The silt and dirt in the water will be filtered by the filter screen on the drain pipe 160. S2. When the silt on the filter screen of the drain pipe 160 accumulates excessively, it affects the flow rate of water. After the blockage occurs, the water level in the inlet tank 100 rises, causing the float plate 340 to drive the entire floating mechanism 300 to move upward together. S3. At this time, the two sets of bending plates 320 respectively clamp the two docking blocks 270 and pull the two connecting ropes 260, thereby driving the spool 220 to rotate in the same direction, and continuously increasing the elastic potential energy of the internal spiral spring 240. S4. When the top of the bending plate 320 comes into contact with the guide block 170, the tops of the symmetrically arranged bending plates 320 bend towards each other, causing the bottom protrusion to loosen the connecting block 270, thereby causing the spring force of the spiral spring 240 to drive the spool 220 to rotate in the opposite direction, thus causing the ratchet 250 to rotate in the opposite direction inside the outer ring 214. S5. After the ratchet 250 comes into contact with several pawls 215, it drives the outer ring 214 to rotate in the opposite direction, causing the shaft 211 to rotate, which in turn causes the worm 212 and the shaft tooth 213 on the shaft 211 to rotate simultaneously. S6. After the worm gear 212 rotates, it drives the rotating ring 140 to rotate through contact with the ring tooth 142, thereby scraping the sludge above the filter screen into the drain pipe 160 for sewage discharge, and allowing water to flow quickly through the drain pipe 160 for drainage. After the shaft tooth 213 rotates, it will continuously push the trapezoidal protrusion under the lower pressure frame 410. Under the elastic force of the second spring 430, the lower pressure frame 410 will move up and down repeatedly. After the round plug 420 moves up and down repeatedly, the flushing water will periodically flush the inside of the water passage hole 141, and the sludge attached to the inner wall of the water passage hole 141 will be flushed away.

[0038] The foregoing description of specific exemplary embodiments of the invention is for illustrative and explanatory purposes. These descriptions are not intended to limit the invention to the precise forms disclosed, and it will be apparent that many changes and variations can be made in accordance with the foregoing teachings.

The waterproofing and drainage equipment suitable for water conservancy construction according to claim 8, characterized in that: The longitudinal section of the outer tube (440) is cross-shaped, the round plug (420) is slidably connected to the inside of the longitudinal tube of the outer tube (440), and the nozzle (450) is snapped and fixed to the top surface of the partition (130).

10. A waterproofing and drainage method suitable for water conservancy construction, using the waterproofing and drainage equipment suitable for water conservancy construction as described in any one of claims 1-9, characterized in that, Includes the following steps: S1. Water flows into the interior of the tank (110) through the grille (190) at the top of the inlet tank (100), and through the drain pipe at the bottom of the tank, through the water passage hole (141) on the rotating ring (140), and into the interior of the drain pipe (160). The silt and dirt in the water flow will be filtered by the filter screen on the drain pipe (160). S2. When the silt on the filter screen of the drain pipe (160) accumulates excessively, it affects the flow rate of water. After the blockage occurs, the water level in the inlet tank (100) rises, causing the float plate (340) to drive the floating mechanism (300) to move upward together. S3. At this time, the two sets of bending plates (320) respectively clamp the two docking blocks (270) and pull the two connecting ropes (260), thereby driving the spool (220) to rotate in the same direction, and continuously increasing the elastic potential energy of the internal spiral spring (240); S4. When the top of the bending plate (320) comes into contact with the guide block (170), the tops of the symmetrically arranged bending plates (320) bend towards each other, and the bottom convex plate loosens the connecting block (270), thereby causing the spring force of the spiral spring (240) to drive the spool (220) to rotate in the opposite direction, thereby causing the ratchet (250) to rotate in the opposite direction inside the outer ring (214); S5. After the ratchet (250) comes into contact with several pawls (215), it drives the outer ring (214) to rotate in the opposite direction, causing the shaft (211) to rotate, which in turn causes the worm (212) and shaft teeth (213) on the shaft (211) to rotate simultaneously. S6. After the worm (212) rotates, it drives the rotating ring (140) to rotate through contact with the ring tooth (142), and scrapes the sludge above the filter screen into the drain pipe (160) for sewage discharge, so that the water flows quickly through the drain pipe (160) for drainage. S7. After the shaft tooth (213) rotates, it will continuously push the trapezoidal protrusion under the lower pressure frame (410). Under the elastic force of the second spring (430), it will drive the lower pressure frame (410) to move up and down repeatedly. After the round plug (420) moves up and down repeatedly, the flushing water will periodically flush the inside of the water hole (141) and flush the sludge attached to the inner wall of the water hole (141).
