Technical Field
[0001] This utility model belongs to the field of drainage equipment technology, and more specifically, it relates to a drainage device for water conservancy engineering construction channels. Background Technology
[0002] Hydraulic construction is the process of constructing, installing, and maintaining water conservancy facilities using technical means. Construction must be planned according to hydrogeological conditions, utilizing mechanical equipment to complete the foundation and main structure, along with supporting auxiliary facilities, to ensure project safety, quality, and progress, and to achieve the intended water conservancy function. Canal drainage equipment, during construction, regulates water levels, removes accumulated water, prevents safety accidents, dries the site, improves construction efficiency, and ensures the smooth progress of the project. A search revealed that Chinese utility model patent CN202323338367.8 provides a canal drainage device for hydraulic engineering construction. This device's gate plate, through the setting of a first drainage mechanism and a second drainage mechanism, allows for the simultaneous activation of two drive motors to move two transverse water-blocking plates to both sides when the canal water level reaches a warning threshold, thereby opening the transverse drainage opening and achieving quantitative discharge of accumulated water from the canal.
[0003] Channels are mostly open in use, and after long-term use, debris easily accumulates in them. The cleaning capacity of the device is insufficient, which causes garbage, silt and other debris to accumulate in the channel, blocking the drainage passage, reducing drainage efficiency and increasing equipment maintenance costs. Utility Model Content
[0004] To address the aforementioned technical problems, this utility model provides a drainage device for water conservancy construction channels, which solves the technical problem that existing drainage devices for water conservancy construction channels have insufficient cleaning capacity, making it difficult to prevent the accumulation of debris in the channel, thereby causing drainage blockage and reducing drainage efficiency.
[0005] The purpose and function of this utility model for a drainage device for a water conservancy engineering construction channel are achieved by the following specific technical means:
[0006] A drainage device for a water conservancy construction channel includes an installation frame. Movable installation slots are formed on two opposite inner sides of the installation frame, and a gate plate is movably mounted within each slot. An installation section is located at the top of the installation frame, and a lifting rod passes through this section, with its bottom end connected to the top of the gate plate. A drive motor is mounted on one side of the installation frame, and a transmission gear is mounted on the shaft end of the drive motor, connecting to the lifting rod. A flow guide is located on one side of the installation frame, and a water level gauge is located on one side of the flow guide. A control box is located on the other side of the installation frame adjacent to the water level gauge, and the control box is electrically connected to both the water level gauge and the drive motor.
[0007] The above technical solution further includes that one side of the guide component passes through the mounting frame, and two sets of mounting plates are correspondingly provided on both sides of the mounting frame. One side of the mounting plate contacts the mounting frame and is connected as a whole by bolts.
[0008] The above technical solution further includes that the flow guide is a hollow frame structure, and an assembly platform is provided inside the flow guide. An interception net is also provided inside the flow guide. The interception net is clipped to one side of the assembly platform, and a filter screen is fixedly connected to the other side of the assembly platform by screws.
[0009] The above technical solution further includes that the guide member is provided with multiple sets of sliding mounting slots, and the intercepting net is provided with mounting parts corresponding to the multiple sets of sliding mounting slots. The intercepting net is slidably installed in the sliding mounting slots through the mounting parts.
[0010] The above technical solution further includes that the bottom end of the guide component is provided with an assembly groove, an assembly frame is provided in the assembly groove, a water pump is provided on the assembly frame, and the water pump is electrically connected to the control box; through grooves are also provided on the inner sides of the two rows of the assembly groove.
[0011] The above technical solution further includes that two sets of mounting brackets are arranged opposite each other inside the flow guide, and nozzles are also provided on the mounting brackets. The nozzles are connected to the water pump through pipelines.
[0012] The above technical solution further includes that a connecting rod is provided at the bottom end of the lifting rod, and a positioning hole is provided at the top end of the gate corresponding to the connecting rod. The connecting rod passes through the positioning hole, and the same set of positioning bolts passes through the connecting rod and the positioning hole. One end of the positioning bolt is also provided with a fixing member for locking the position.
[0013] Compared with the prior art, the present invention has the following beneficial effects:
[0014] 1. The drainage component features a double-layer interception structure: an upper interception net and a lower filter screen. The interception net's side mounting brackets are embedded in the drainage component's sliding mounting groove, allowing for horizontal sliding installation and removal. The filter screen is secured to the drainage component's assembly platform with screws. In use, the interception net blocks large debris such as twigs and plastic bags, while the filter screen filters out fine particles like sand, gravel, and leaf debris. This double interception reduces debris entering the drainage path. An internal water pump connects to the spray head via piping. When powered, the pump delivers water to the spray head, creating a high-pressure jet that impacts the inner wall of the drainage component and the drainage channel, directly impacting and removing attached debris from the interception structure. This automated cleaning further prevents drainage blockages and improves water flow.
[0015] 2. Through the linkage of the control box, water level gauge, and drive motor, when the water level gauge detects water level data and transmits it to the control box, the control box automatically controls the drive motor to rotate the transmission gears, thereby driving the lifting rod to move up and down, realizing the raising and lowering of the gate. The size of the drainage channel opening can be precisely adjusted according to the water level to control the drainage volume and ensure stable drainage efficiency. Attached Figure Description

[0025] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate the technical solution of this utility model, but should not be used to limit the scope of protection of this utility model. Example
[0026] like Figures 1 to 7 As shown, this utility model provides a drainage device for a water conservancy engineering construction channel, including an installation frame 1. Movable installation grooves are provided on two opposite inner sides of the installation frame 1, and a gate 2 is movably mounted within these grooves. An installation part 101 is also provided at the top of the installation frame 1, through which a lifting rod 3 passes, with its bottom end connected to the top of the gate 2. A drive motor 4 is also provided on one side of the installation frame 1 of the installation part 101, and a transmission gear 102 is provided at the shaft end of the drive motor 4, connecting to the lifting rod 3. A flow guide 103 is also provided on one side of the installation frame 1, and a water level gauge 5 is provided on one side of the flow guide 103. A control box 104 is also provided on the other side of the installation frame 1 adjacent to the water level gauge 5, and the control box 104 is electrically connected to both the water level gauge 5 and the drive motor 4. The installation frame 1 serves as the main structure, the movable installation grooves provide a track for the gate 2 to move up and down, and the installation part 101 fixes the lifting rod 3 to maintain stability during rotation. The drive motor 4 engages with the lifting rod 3 through the transmission gear 102, converting the motor's rotational power into the linear lifting power of the lifting rod 3, ensuring the accurate operation of the gate 2, and thus forming a stable transmission system.
[0027] A flow guide 103 is located on one side of the mounting frame 1. Its internal structure is funnel-shaped, changing the direction of water flow and allowing it to pass through the drainage equipment in an orderly manner. The flow guide 103, in conjunction with the mounting frame 1, can initially intercept debris in the water flow, reducing the risk of blockage of the gate 2 and subsequent drainage channels, and ensuring the normal operation of the drainage equipment. A water level gauge 5 on one side monitors the channel water level and transmits the data to the control box 104. The control box 104 controls the drive motor 4 to operate according to a preset threshold. The drive gear 102 at the shaft end of the drive motor 4 drives the lifting rod 3 to rotate. The lifting rod 3, connected to the gate 2, allows the gate 2 to move up and down within the movable mounting slot, thereby adjusting the size of the drainage channel opening within the mounting frame 1 and precisely controlling the drainage volume.
[0028] like Figures 1 to 3 As shown, one side of the guide member 103 is inserted into the mounting frame 1, and two sets of mounting plates 201 are correspondingly provided on both sides of the mounting frame 1. One side of the mounting plate 201 contacts the mounting frame 1 and is connected as a whole by bolts. The two sets of mounting plates 201 are respectively set on both sides of the mounting frame 1, and the mounting plates 201 are fastened to the mounting frame 1 by bolts, forming a clamping and fixing of the guide member 103. This ensures that the part of the guide member 103 inserted into the mounting frame 1 is stable and does not loosen, ensuring that the guide member 103 and the mounting frame 1 maintain a constant relative position under the impact of water flow, and maintaining the overall structural stability of the equipment. The mounting plate 201 is in close contact with the mounting frame 1, and the bolts can make the two tightly connected during the tightening process, effectively preventing water from leaking from the connection between the guide member 103 and the mounting frame 1, ensuring that the water flows through the channel inside the guide member 103 and the mounting frame 1 according to the path, and ensuring that the drainage function is realized normally.
[0029] Meanwhile, the bolted connection method allows for easy removal of the guide plate 201 from the mounting frame 1 when the guide component 103 needs to be inspected, cleaned, or replaced. This reduces the difficulty of equipment maintenance and improves maintenance efficiency.
[0030] like Figure 1 , Figure 3 and Figure 4 As shown, the flow guide 103 is a hollow frame structure, and an assembly platform 301 is provided inside the flow guide 103. An intercepting net 302 is also installed inside the flow guide 103. The intercepting net 302 is snapped onto one side of the assembly platform 301, and a filter screen 303 is fixedly connected to the other side of the assembly platform 301 by screws. The flow guide 103 also has multiple sets of sliding mounting slots 401. The intercepting net 302 is also provided with mounting parts 402 corresponding to the multiple sets of sliding mounting slots 401. The intercepting net 302 is slidably installed in the sliding mounting slots 401 through the mounting parts 402. The assembly platform 301 provides a supporting plane for the intercepting net 302 and the filter screen 303. The snapping of the intercepting net 302 and the screw fixing of the filter screen 303 ensure that their positions are fixed inside the flow guide 103. The sliding mounting groove 401 and the mounting component 402 restrict the movement direction of the interceptor net 302, maintaining stability under water flow impact and extending its service life. An assembly platform 301 is provided inside the guide component 103, where the interceptor net 302 and filter screen 303 are installed in layers on both sides. The interceptor net 302, located upstream, intercepts larger debris first, while the filter screen 303, located downstream, filters smaller particles, forming a double-layer interception structure that graded and blocked debris of different sizes, reducing the amount of debris entering the drainage path.
[0031] The interceptor net 302 is installed and removed by sliding along the groove 401 of the guide element 103 via the mounting part 402. The filter screen 303 is fixed to the assembly table 301 with screws, and can be removed by unscrewing the screws. These two methods simplify the cleaning and replacement of the interceptor net 302 and the filter screen 303, reducing maintenance workload.
[0032] like Figure 3 and Figure 7 As shown, the bottom of the guide vane 103 is also provided with an assembly groove, and an assembly frame is provided in the assembly groove. The assembly frame is also provided with a water pump 6, which is electrically connected to the control box 104. Through grooves 501 are also provided through the inner sides of the two rows of the assembly groove. Two sets of mounting frames are also provided opposite to each other in the guide vane 103. The mounting frames are also provided with nozzles 601, which are connected to the water pump 6 through pipelines. The water pump 6 is installed in the assembly groove at the bottom of the guide vane 103, and the nozzles 601 are fixed by the mounting frames set up in the internal space. The cleaning system is formed by connecting them through pipelines. The cleaning function components are integrated into the guide vane 103, reducing the external connection of the equipment, reducing the overall volume, and making the structure compact.
[0033] The control box 104, in conjunction with the water level gauge 5, controls the start of the water pump 6. The water pump 6 draws water from the through channels 501 on both sides of the assembly slot, and delivers it through pipelines to the nozzles 601 to spray out high-pressure water. The water flow directly washes the channel, the interior of the guide component 103, and the surfaces of the interceptor net 302 and the filter screen 303, washing away attached debris and achieving automatic cleaning, reducing manual cleaning operations.
[0034] like Figure 2 and Figure 6 As shown, a connecting rod 701 is provided at the bottom of the lifting rod 3, and a positioning hole is also provided at the top of the gate plate 2 corresponding to the connecting rod 701. The connecting rod 701 passes through the positioning hole, and the same set of positioning bolts 702 passes through the connecting rod 701 and the positioning hole. One end of the positioning bolt 702 is also provided with a fixing component for locking the position. The positioning hole cooperates with the connecting rod 701 to limit the installation position and angle of the gate plate 2, ensuring that the gate plate 2 moves accurately in the movable installation slot. At the same time, the fixing component locks the positioning bolt 702 to prevent it from loosening and falling off during equipment operation, avoiding connection failure between the lifting rod 3 and the gate plate 2. The multiple fixing structures enhance the overall connection reliability, ensure the long-term stable operation of the drainage equipment, and guarantee the normal realization of the drainage function.
[0035] The positioning bolt 702 passes through the positioning hole and the connecting rod 701, further fixing its position and preventing the gate 2 from being misaligned, which could affect the adjustment accuracy of the drainage channel opening. The connection method of the positioning bolt 702 and the fixing component allows for easy disassembly; simply remove the fixing component and pull out the positioning bolt 702 to separate the connecting rod 701 from the gate 2. This facilitates individual inspection and replacement of the gate 2 or the lifting rod 3, reducing equipment maintenance difficulty and improving maintenance efficiency.
[0036] The above description is merely an embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
