Description

Technical Field

[0001] The present invention relates to the technical field of drainage systems, and in particular to a water supply and drainage device and method for construction engineering. Background Art

[0002] The drainage system refers to the collection, transportation, water treatment and discharge of drainage. In order to meet environmental protection requirements during construction, it is usually necessary to set up construction vehicle washing facilities at the exit of the construction site and build a drainage system to discharge sewage.

[0003] The Chinese patent disclosed "A rainwater drainage structure for construction with sediment filtering function" with application number 202310385635.7 includes a frame, the frame includes a panel, a first fixed plate is fixedly connected to the side of the lower surface of the panel, a sand storage ring is fixedly connected to the end of the first fixed plate away from the panel, a funnel is fixedly connected to the lower surface of the sand storage ring, a first support frame is fixedly connected to the upper surface of the panel, a buffer pipe is fixedly connected to the end of the first support frame away from the panel, the water outlet end of the buffer pipe passes through the panel, a limiting frame is fixedly connected to the upper surface of the buffer pipe, and a sand-water separation device includes a limiting ring, the limiting ring is fixedly connected to the outer surface of the buffer pipe, and a rotating rod is rotatably connected to the groove of the limiting ring.

[0004] However, since the wastewater from washing construction vehicles contains a large amount of soil blocks and unsolidified concrete slag, although these solid impurities can be effectively intercepted and collected by the filter screen to effectively prevent the sewer pipe from being blocked, the filter screen will be continuously exposed to the water surface as the construction vehicle is intermittently washed. At this time, the water in the concrete slag and soil blocks on the filter screen will evaporate rapidly, thereby solidifying (especially in summer). The solidified soil blocks and concrete slag will adhere to the filter screen, which not only affects drainage but also makes it difficult to clean up later. Therefore, the present invention proposes a water supply and drainage device and method for construction projects to optimize the existing drainage system. Summary of the invention

[0005] The object of the present invention is to provide a water supply and drainage device and method for construction engineering, which solves the problem that after the water in the existing drainage device is drained, the soil blocks and concrete residues on the filter screen are easily dehydrated and solidified, resulting in difficulty in subsequent cleaning.

[0006] To achieve the above object, the present invention provides the following technical solution: a water supply and drainage device for construction engineering, comprising a drainage frame and a grille located above the drainage frame, and further comprising: The anti-solidification mechanism includes a filter screen and a water level sensor. The lower end surface of the filter screen is provided with a lifting assembly, the lifting assembly includes a third round rod, and the end of the third round rod is provided with an opening and closing assembly. When the vehicle is washed, the water level sensor detects that the water level is lowered, the lifting assembly drives the filter screen to descend, and the third round rod drives the opening and closing assembly to close the drainage frame, so that the drainage frame stops draining water, and the filter screen sinks into the water. The disinfection mechanism comprises a disinfection box, a suction assembly is arranged below the disinfection box, and the suction assembly is connected to the third round rod through a pull rope; when the drainage frame stops draining, the third round rod controls the suction assembly through the pull rope to make the disinfectant in the disinfection box enter the drainage frame.

[0007] Preferably, the lifting assembly comprises an electric telescopic rod, which is fixedly mounted on the outer wall of the drainage frame, and the output shaft of the electric telescopic rod passes through the drainage frame and is fixedly connected to the third round rod.

[0008] Preferably, a second round rod is symmetrically mounted on the outer wall of the third round rod, connecting rods are symmetrically rotatably mounted at both ends of the second round rod, a fixing rod is rotatably mounted on one end of the connecting rod away from the second round rod, and the fixing rod is fixedly mounted on the filter screen.

[0009] Preferably, a sliding groove is provided on the outer wall of the connecting rod, a first round rod is slidably mounted on the inner wall of the sliding groove, and both ends of the first round rod are rotatably mounted on the drainage frame.

[0010] Preferably, the opening and closing assembly includes a first pipe, the first pipe is installed on the outer wall of the drainage frame, the outer wall of the first pipe is connected to the second pipe, the inner wall of the first pipe is slidably mounted with a first piston, and the first piston is fixedly connected to the third round rod.

[0011] Preferably, the outer wall of the pull rope is abutted against a first pulley and a second pulley, and the first pulley and the second pulley are fixedly mounted on the first pipe.

[0012] Preferably, the suction assembly includes a cylinder fixedly mounted on the lower end surface of the disinfection box, a second piston is slidably mounted on the inner wall of the cylinder, a spring and a piston rod are respectively fixedly mounted at both ends of the second piston, the piston rod is fixedly connected to the pull rope, and the upper end surface of the spring is mounted on the disinfection box.

[0013] Preferably, a discharge pipe and a feed pipe are respectively installed on the outer wall of the cylinder, the discharge pipe is connected to the drainage frame, and the feed pipe is connected to the disinfection box.

[0014] Preferably, a support plate is symmetrically mounted on the lower end surface of the disinfection box, and the support plate is fixedly mounted on the outer wall of the drainage frame.

[0015] Preferably, the water supply and drainage method for construction engineering comprises the following steps: Step 1: When the engineering vehicle is flushing, the grille isolates the large soil blocks and concrete blocks, and the small blocks will enter the drainage frame with the water. At this time, the filter screen separates the water, soil blocks and concrete slag again, and the water will flow out of the drainage frame; Step 2: When the vehicle is cleaned, the amount of water in the drainage frame decreases. The water level sensor detects that the water is getting less, so the lifting component drives the filter down. At the same time, the third round rod drives the opening and closing component to stop the drainage frame from draining water, and the filter sinks into the water. Step 3: When the water in the drainage frame is no longer discharged, the third round rod drives the suction assembly to work through the pull rope, so that the disinfectant in the disinfection box enters the drainage frame.

[0016] Compared with the prior art, the present invention has the following beneficial effects: 1. The present invention is provided with a lifting assembly and an opening and closing assembly. When the electric telescopic rod drives the third round rod to move, the third round rod further drives the second round rod, the first piston and the pull rope to move. At this time, the second round rod drives its slide groove to slide on the first round rod through the connecting rod, and the other end of the connecting rod drives the fixed rod to move downward. The fixed rod drives the filter to descend. At the same time, the movement of the first piston will block the second pipe, preventing the water in the drainage frame from continuing to be discharged, and the filter will sink into the water. At this time, the soil blocks and concrete residues above the filter will not solidify to block the filter holes, and it is convenient for subsequent cleaning.

[0017] 2. The present invention is provided with a water level sensor, which can promptly notify the staff when the water level drops. After the staff removes the grille, they control the filter screen through the lifting assembly to make it higher than the drainage frame. At this time, since the soil blocks and concrete residues are not solidified, they can be cleaned with a broom, which is convenient and quick.

[0018] 3. The present invention is provided with a disinfection mechanism. When the third round rod drives the pull rope to move, the pull rope slides on the first pulley and the second pulley, and drives the piston rod to descend. The piston rod then drives the second piston to descend, and the spring is stretched. At this time, the disinfectant in the cylinder enters the drainage frame through the discharge pipe, disinfects the stored water, and prevents bacteria from growing.

DETAILED DESCRIPTION

[0021] See also Figures 1 to 8 The present invention provides a technical solution: a water supply and drainage device for construction engineering, comprising a drainage frame 1 and a grille 3 located above the drainage frame, and further comprising: The anti-curing mechanism includes a filter screen 15 and a water level sensor 21.

An opening and closing assembly is provided at the end of the third round rod 20. When the vehicle is washed, the water level sensor 21 detects that the water level is lowered, the lifting assembly drives the filter screen 15 to descend, and the third round rod 20 drives the opening and closing assembly to close the drainage frame 1, so that the drainage frame 1 stops draining, and the filter screen 15 sinks into the water. The disinfection mechanism includes a disinfection box 4, a suction assembly is arranged below the disinfection box 4, and the suction assembly is connected to the third round rod 20 through a pull rope 9; when the drainage frame 1 stops draining, the third round rod 20 controls the suction assembly through the pull rope 9 to allow the disinfectant in the disinfection box 4 to enter the drainage frame 1.

[0022] Further, such as Figure 7 As shown, the lifting assembly includes an electric telescopic rod 2, which is fixedly mounted on the outer wall of the drainage frame 1. The output shaft of the electric telescopic rod 2 passes through the drainage frame 1 and is fixedly connected to the third round rod 20; when the electric telescopic rod 2 is working, it drives the third round rod 20 to move.

[0023] Further, such as Figure 7As shown, the second round rod 19 is symmetrically installed on the outer wall of the third round rod 20, and the connecting rods 17 are symmetrically rotatably installed at both ends of the second round rod 19. The fixing rod 16 is rotatably installed at one end of the connecting rod 17 away from the second round rod 19, and the fixing rod 16 is fixedly installed on the filter screen 15. A sliding groove is provided on the outer wall of the connecting rod 17, and the first round rod 18 is slidably installed on the inner wall of the sliding groove. Both ends of the first round rod 18 are rotatably installed on the drainage frame 1; when the third round rod 20 moves, it drives the second round rod 19 to move, and the second round rod 19 drives the connecting rod 17 to make the internal sliding groove slide on the first round rod 18, thereby driving the filter screen 15 to move up and down in the drainage frame 1 through the fixing rod 16.

[0024] Further, such as Figure 7 As shown, the opening and closing assembly includes a first pipe 5, which is installed on the outer wall of the drainage frame 1. The outer wall of the first pipe 5 is connected to the second pipe 6. A first piston 22 is slidably installed on the inner wall of the first pipe 5. The first piston 22 is fixedly connected to the third round rod 20; when the third round rod 20 drives the first piston 22 to move, it can control the opening and closing of the second pipe 6.

[0025] Further, such as Figure 7 As shown, the outer wall of the pull rope 9 is abutted with a first pulley 8 and a second pulley 10 , and the first pulley 8 and the second pulley 10 are fixedly mounted on the first pipe 5 ; the first pulley 8 and the second pulley 10 reduce the friction of the pull rope 9 .

[0026] Further, such as Figure 7 and Figure 8 As shown, the suction assembly includes a cylinder 11 fixedly mounted on the lower end surface of the disinfection box 4, a second piston 24 is slidably mounted on the inner wall of the cylinder 11, a spring 23 and a piston rod 14 are respectively fixedly mounted on both ends of the second piston 24, the piston rod 14 is fixedly connected to the pull rope 9, the upper end surface of the spring 23 is mounted on the disinfection box 4, a discharge pipe 12 and a feed pipe 13 are respectively mounted on the outer wall of the cylinder 11, the discharge pipe 12 is connected to the drainage frame 1, and the feed pipe 13 is connected to the disinfection box 4; when the pull rope 9 drives the piston rod 14 to move downward, the piston rod 14 drives the second piston 24 to descend, at this time the disinfectant in the cylinder 11 enters the drainage frame 1 from the discharge pipe 12, when the pull rope 9 is loosened, the spring 23 is reset, so that the pull rope 9 is tightened to prevent deviation, and at the same time drives the second piston 24 back to the initial position, at this time the disinfectant enters the cylinder 11 from the disinfection box 4 through the feed pipe 13.

[0027] Further, such as Figure 2 As shown, a support plate 7 is symmetrically mounted on the lower end surface of the disinfection box 4 , and the support plate 7 is fixedly mounted on the outer wall of the drainage frame 1 ; the support plate 7 supports the disinfection box 4 .

[0028] Further, such as Figure 8 As shown, both the discharge pipe 12 and the feed pipe 13 are equipped with one-way valves; when the second piston 24 descends, the one-way valve in the discharge pipe 12 opens, and the one-way valve in the feed pipe 13 closes; when the second piston 24 rises, the one-way valve in the discharge pipe 12 closes, and the one-way valve in the feed pipe 13 opens.

[0029] In this embodiment, the water supply and drainage method for construction engineering comprises the following steps: Step 1: After the device is connected to an external power supply and controller, when the engineering vehicle is flushed, the grille 3 isolates large soil blocks and concrete blocks, and small blocks will enter the drainage frame 1 with water. At this time, the filter 15 separates water, soil blocks and concrete slag again. The soil blocks and concrete slag are on the filter 15, and the water enters the second pipe 6 from the first pipe 5 and then is discharged; Step 2: After the vehicle is cleaned, the amount of water in the drainage frame 1 gradually decreases. When the water level sensor 21 detects that the water level has dropped, the feedback controller shrinks the electric telescopic rod 2, which drives the third round rod 20 to move. The third round rod 20 then drives the second round rod 19, the first piston 22 and the pull rope 9 to move. At this time, the second round rod 19 drives its slide groove to slide on the first round rod 18 through the connecting rod 17, and the other end of the connecting rod 17 drives the fixed rod 16 to move downward. The fixed rod 16 drives the filter 15 to descend. At the same time, the movement of the first piston 22 will block the second pipe 6, preventing the water in the drainage frame 1 from continuing to be discharged, and the filter 15 will sink into the water. At this time, the soil and concrete residue above the filter 15 will not solidify, which is convenient for subsequent cleaning.

[0030] Step 3: When the third round rod 20 drives the pull rope 9 to move, the pull rope 9 slides on the first pulley 8 and the second pulley 10, and drives the piston rod 14 to descend. The piston rod 14 then drives the second piston 24 to descend, and the spring 23 is stretched. At this time, the disinfectant in the cylinder 11 enters the drainage frame 1 through the discharge pipe 12, disinfecting the stored water to prevent bacteria from growing.

[0031] Step 4: When the device is in an idle state, or the water level sensor 21 detects that the water level drops further, the staff can first remove the grille 3, and then control the electric telescopic rod 2 to extend, drive the third round rod 20 to move, and then drive the second round rod 19, the first piston 22 and the pull rope 9 to move. At this time, the second round rod 19 drives the filter screen 15 to rise through the connecting rod 17 and the fixed rod 16, and extends out of the drainage frame 1. Since the soil and concrete residue have not yet solidified, the staff can easily use a broom to clean them. At the same time, the first piston 22 no longer blocks the second pipe 6, and the water inside the drainage frame 1 will all flow out. The spring 23 will shrink and return to the initial position, and the disinfectant in the cylinder 11 will be refilled to prepare for the next disinfection.

[0032] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
