Description

Technical Field

[0001] The present invention relates to the technical field of water conservancy engineering, and more specifically, to a waterproof drainage device for water conservancy engineering construction. Background Art

[0002] Water conservancy projects are projects built to control and allocate surface water and groundwater in nature, so as to achieve the goal of eliminating harm and promoting benefits. Water is an indispensable resource for human production and life, but in most cases its natural state does not meet human needs. Therefore, water conservancy projects are built to control water flow, prevent floods and disasters, regulate and distribute water volume, and thus meet people's needs for water resources in life and production. Water conservancy projects require the construction of dams, dikes, spillways, sluices, water inlets, channels, ferries, valves and other hydraulic structures to achieve the goal. During the construction of water conservancy projects, foundation pits need to be excavated. During the foundation pit excavation construction process, groundwater will seep into the foundation pit and mix with silt, particulate matter, and debris in the soil to form muddy water. The more muddy water accumulates, the more it will affect the normal progress of the water conservancy project construction. It is necessary to use water conservancy project construction waterproofing and drainage devices to discharge the muddy water in the foundation pit, so as to achieve the purpose of waterproofing and drainage.

[0003] A Chinese patent with authorization announcement number CN114635390B discloses a new waterproof drainage device for water conservancy project construction, including a drainage box, and also includes: a vibration component, a filter screen, a transmission component, a drive shaft, blades, a material receiving box, a driven shaft, an eccentric column and a rotating cylinder; the drainage box is provided with an avoidance groove, a drainage port and a water inlet, a water stop valve is fixedly installed on the drainage port, a filter screen is rotatably connected in the drainage box, and a plurality of rectangular filter holes are provided on the filter screen.

[0004] The above method improves the drainage efficiency and solves the problem of filter blockage to a certain extent by introducing mechanical vibration and cleaning components. Specifically, the device uses water flow to drive the blades to rotate, and then drives the filter to vibrate and the cleaning components to rotate through the transmission system to achieve preliminary self-cleaning of the filter. However, this self-cleaning component still has certain limitations in practical applications. First of all, for impurities with large volume and heavy weight (such as large particles of mud, gravel, etc.), it is often difficult to completely remove them by just vibrating the filter and scraping the cleaning rod. Impurities are easy to accumulate on the surface or pores of the filter. As time goes by, the water permeability of the filter is gradually reduced, which eventually leads to a significant decrease in drainage efficiency or even complete blockage; secondly, the drainage box is a closed structure, which is not convenient for manual cleaning of the filter.

[0005] Therefore, a new solution needs to be proposed to solve this problem. Summary of the invention

DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of the present application provides a waterproof drainage device for water conservancy project construction, including a frame 1, a water pump 2 arranged on the frame 1, and a water pumping pipe 3 connected to the water inlet end of the water pump 2. The water pump 2 can adopt the silt water pump 2 in the prior art, so that muddy water mixed with silt or gravel is not easy to damage the water pump 2. The water pumping pipe 3 is a hose, which can be extended into the foundation pit of the water conservancy project construction site to be pumped. It also includes a water inlet box 5 and a water outlet box 6 arranged on the frame 1. The water outlet end of the water pump 2 is connected to the water inlet box 5 through the water outlet pipe 4. The water inlet box 5 is provided with a water receiving bucket 14 with a filter hole 1421 at the bottom and an eccentric opening 144 at the top. The eccentric opening 144 of the water receiving bucket 14 is directly opposite to the water outlet position of the water outlet pipe 4. The bottom of the water inlet box 5 is provided with a guide port 51 for guiding muddy water into the water outlet box 6, and a filter plate 11 is detachably connected between the guide port 51 and the outside of the water outlet box 6. The water receiving bucket 14 is configured such that when the muddy water in the water receiving bucket 14 is not full, the eccentric opening 144 remains in a vertically upward state, and when the muddy water in the water receiving bucket 14 is full, the eccentric opening 144 is at least partially tilted, so that part of the muddy water is poured to the bottom of the water inlet box 5.

[0030] The above-mentioned water conservancy project construction waterproof drainage device includes the following working steps:

[0031] S1. When the water conservancy project construction site needs to be drained, the water pump 2 arranged on the frame 1 is started, and the water pump 2 penetrates into the foundation pit to be pumped through the water pumping pipe 3 connected to its water inlet end to extract muddy water containing silt or gravel;

[0032] S2, the water pump 2 introduces the extracted muddy water into the water inlet box 5 arranged on the frame 1 through the water outlet pipe 4 connected to its water outlet end. A water receiving bucket 14 is arranged in the water inlet box 5. The bottom of the water receiving bucket 14 has a filter hole 1421, which allows some fine particles or water in the muddy water to pass through, while larger impurities are initially intercepted. The top of the water receiving bucket 14 is designed as an eccentric opening 144, which is directly opposite to the water outlet position of the water outlet pipe 4. When the muddy water in the water receiving bucket 14 is not full, the eccentric opening 144 remains in a vertical upward state to ensure that the muddy water can smoothly flow into the water receiving bucket 14;

[0033] S3, when the muddy water in the water receiving bucket 14 accumulates to an overflowing state, due to the weight and fluidity of the muddy water, the eccentric opening 144 of the water receiving bucket 14 will at least partially tilt, so that part of the muddy water pours out from the eccentric opening 144 and flows directly to the bottom of the water inlet box 5;

[0034] S4. After completing step S3, the filter disc 11 is used to further filter the muddy water flowing out from the bottom of the water inlet tank 5 to intercept finer impurities. The muddy water filtered by the filter disc 11 eventually enters the water outlet tank 6 and can be further discharged to a designated area or subjected to subsequent treatment through the water outlet tank 6.

[0035] In the above method, by adopting the setting of the water receiving bucket 14 and the eccentric opening 144, when the muddy water in the water receiving bucket 14 reaches a certain capacity, the eccentric opening 144 will automatically tilt, causing part of the muddy water to pour into the bottom of the water inlet box 5 in a pouring manner, rather than simply slowly infiltrating through the filter hole 1421. This not only speeds up the separation of muddy water and impurities, but also effectively avoids the blockage problem caused by the accumulation of impurities in the filter hole 1421, effectively improving the drainage efficiency. At the same time, by detachably connecting the filter plate 11 between the guide port 51 and the outside of the water outlet box 6, the muddy water can be filtered for the second time, thereby improving the cleanliness of the muddy water. The filter plate 11 is set outside the water outlet box 6, which is conducive to manual and quick cleaning of impurities on the filter plate 11. Therefore, the device is not easy to be blocked. While ensuring the drainage efficiency, it can also achieve long-term, stable and efficient operation, thereby providing a strong guarantee for the smooth construction of water conservancy projects.

[0036] In this embodiment, Figure 4 and Figure 5 As shown, the water inlet box 5 is provided with a hinged portion 53, and the water receiving bucket 14 is hinged on the hinged portion 53. The water receiving bucket 14 includes a counterweight portion 141, a sand settling portion 142 and a water receiving portion 143 which are arranged in sequence from bottom to top. The filter hole 1421 is arranged through the bottom of the water receiving portion 143. The counterweight portion 141 is suitable for balancing the center of gravity of the water receiving bucket 14 so that when the muddy water is not full, the eccentric opening 144 maintains a vertical upward state, and the volume of the water receiving portion 143 is greater than the volume of the sand settling portion 142. The eccentric opening 144 is formed on the water receiving portion 143.

[0037] In the above manner, by arranging the hinge part 53 on the water inlet box 5, the water receiving bucket 14 can be flexibly hinged and automatically balance the center of gravity, ensuring that the eccentric opening 144 remains vertically upward when the muddy water is not full, effectively preventing splashing. By setting the counterweight part 141, when the muddy water is not full, even if there is an eccentric opening 144, the water receiving bucket 14 can maintain a stable state of vertically upward, avoiding tipping or tilting due to unstable center of gravity, and ensuring the smooth progress of the water receiving process.

[0038] In this embodiment, a convergence port 52 is provided at the bottom of the water inlet box 5, which contracts from the periphery to the center, and the outlet 51 is connected to the convergence port 52. The setting of the convergence port 52 allows the muddy water entering the bottom of the water inlet box 5 to be quickly concentrated to the center, reducing the range of the muddy water spreading at the bottom of the box, thereby improving the efficiency of collecting the muddy water and introducing it into the outlet 51.

[0039] In this embodiment, Figure 1 and Figure 6 As shown, an operation port 16 is provided on one side of the water inlet box 5, and a cover plate 19 is provided on the water inlet box 5 for opening and closing the operation port 16. The setting of the operation port 16 enables the staff to easily open the cover plate 19 and directly access the inside of the water inlet box 5 and the water receiving bucket 14, so as to conveniently carry out daily maintenance, cleaning and necessary repair work.

[0040] In this embodiment, the cover plate 19 is slidably connected to the water inlet tank 5 through a slide rail pair 15, a cylinder 18 is fixed on the frame 1, a piston rod of the cylinder 18 is fixedly connected to the cover plate 19, a decorative panel 17 is provided on the water inlet tank 5 in front of the cover plate 19, a slide groove for sliding the cover plate 19 is provided between the decorative panel 17 and the water inlet tank 5, an opening opposite to the operating port 16 is also provided on the decorative panel 17, and the size of the opening is smaller than the size of the cover plate 19.

[0041] In the above method, the cover 19 is slidably connected to the water inlet tank 5 through the slide rail pair 15, and is driven by the cylinder 18 to realize automatic opening and closing, which not only improves the convenience of operation, but also keeps the equipment neat and beautiful. The slide groove and opening design on the decorative panel 17 not only ensure the smooth sliding of the cover 19, but also limit the maximum opening position of the cover 19, while shielding the internal structure, enhancing the safety and appearance of the equipment.

[0042] In this embodiment, Figure 7 As shown, the water outlet box 6 is located at the lower side of the water inlet box 5, and a drain port 62 is provided on the top of the water outlet box 6. The filter plate 11 is placed on the water outlet box 6 at the drain port 62. A drain pipe 61 is provided on the water outlet box 6, and a drain valve is provided on the drain pipe 61.

[0043] In the above method, the water outlet box 6 is located at the lower side of the water inlet box 5, which is conducive to the natural flow of muddy water under the action of gravity, reducing the energy consumption and resistance in the drainage process. At the same time, the setting of the water outlet 62 allows the filtered muddy water to smoothly enter the water outlet box 6, further improving the drainage efficiency.

[0044] In this embodiment, Figure 2As shown, the frame 1 is provided with a water storage barrel 8 and a water pump system 9 for pumping water in the water outlet tank 6 into the water storage barrel 8, and the water pump system 9 includes a water pump and related connecting pipes. The filtered water is pumped from the water outlet tank 6 into the water storage barrel 8 by the water pump system 9, thereby realizing the effective recovery and utilization of water resources, reducing the waste of water resources in the construction of water conservancy projects, reducing construction costs, and complying with the concept of sustainable development.

[0045] In this embodiment, an impurity collection box 7 is also provided on the frame 1, and a ladder 10 is extended from the impurity collection box 7 toward the ground. A discharge opening is provided on one side of the impurity collection box 7, and a discharge door 12 that can open and close the discharge opening is provided on the impurity collection box 7. The bottom of the discharge door 12 is hinged to the impurity collection box 7, and the top is connected to the impurity collection box 7 by a buckle lock 13.

[0046] In the above manner, through the setting of the impurity collection box 7, impurities such as mud, gravel, etc. intercepted during the filtration process can be manually collected into the impurity collection box 7, and the discharge door 12 adopts the setting of hinges and snap locks 13, which not only ensures the sealing of the discharge port, but also facilitates rapid opening and closing, so that the staff can discharge the impurities at any time according to needs, thereby improving work efficiency and flexibility.

[0047] In this embodiment, Figure 8 and Fig. 9 As shown, it also includes a water intake component 20, which includes a bracket 201, a buoyancy ball 202 fixed to the top of the bracket 201, and a plug rod 203 fixed to the bottom of the bracket 201. The plug rod 203 is provided with a base frame 205 and a sliding frame 204 facing each other. The base frame 205 is located below the sliding frame 204 and is fixedly connected to the plug rod 203. The sliding frame 204 is slidably connected to the plug rod 203. The base frame 205 is fixed with a honeycomb tube 206. The tube 206 includes a plurality of honeycomb holes 2061, the sliding frame 204 is provided with a pin 209 which can be inserted into the honeycomb hole 2061, the bracket 201 is provided with a driving member 208 for driving the sliding frame 204 to slide toward the base frame 205, the end of the honeycomb tube 206 away from the pin 209 is connected to a junction 207, the junction 207 is connected to a connector 2071, and the end of the pumping pipe 3 away from the water pump 2 is connected to the connector 2071.

[0048] In the above method, by setting the buoyancy ball 202 and the bracket 201, the water intake component 20 can automatically adjust the height as the water level rises and falls, ensuring that when the water level is deep, the honeycomb tube 206 will not directly contact the bottom of the foundation pit, which is beneficial to reduce the amount of sediment extracted. When the water level is shallow, the rod 203 can be inserted into the soil layer to support the water intake component 20, so that the honeycomb tube 206 can be accurately positioned to the target position during the water intake process. It should be noted that when the water level is shallow, some sediment will inevitably be extracted. The honeycomb tube 206 and the multiple honeycomb holes 2061 thereon increase the contact area with the water body, which is conducive to collecting muddy water faster and more evenly. At the same time, the honeycomb hole 2061 structure also has a certain preliminary filtering effect, which can reduce the entry of impurities into the subsequent water treatment system and protect water pumps and other equipment from damage. At the same time, through the setting of the driving member 208 and the ejector pin 209, when the honeycomb hole 2061 is blocked, it can be unblocked by the ejector pin 209. The driving member 208 can be specifically controlled by setting a PLC controller. The specific control method adopts the existing technology and is not repeated in this embodiment.

[0049] In this embodiment, the driving member 208 is an electric cylinder fixed on the bracket 201, and the output end of the electric cylinder is fixedly connected to the sliding frame 204. The electric cylinder is specifically an electric cylinder with good waterproof performance.

[0050] The above is only a preferred embodiment of the present invention, and the protection scope of the present invention is not limited to the above embodiments. All technical solutions under the concept of the present invention belong to the protection scope of the present invention. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the present invention should also be regarded as the protection scope of the present invention.
