Description

Technical Field

[0001] This utility model relates to the field of building construction drainage technology, specifically a drainage device for building construction. Background Technology

[0002] During construction, large amounts of water can easily accumulate due to foundation pit excavation, dewatering of work surfaces, and rainwater accumulation. If not drained in time, this can affect construction progress, damage the foundation structure, and potentially cause safety hazards. Construction drainage systems, as key equipment, mainly consist of water collection components, pumping mechanisms, delivery pipelines, and control components. They enable the rapid collection and drainage of water in the construction area, ensuring the orderly progress of the construction process.

[0003] Existing drainage systems for construction sites can generally meet the needs of draining accumulated water, quickly lowering the water level in the construction area and preventing foundation damage from soaking. Some systems also have simple filtration functions, reducing the risk of pipe blockage and providing basic protection for construction safety. However, existing systems still have shortcomings: submersible pumps are directly thrown into the bottom of the sump, easily absorbing silt from the bottom of the pit; silt can clog the pump's flow channels, causing a sharp drop in pumping efficiency, accelerating wear on internal pump components, shortening equipment lifespan, and increasing the frequency of shutdowns for cleaning, thus affecting construction progress. Therefore, we provide a construction site drainage system that solves these problems. Utility Model Content

[0004] 1) Technical problems to be solved

[0005] This utility model proposes a drainage device for building construction. Through the cooperation of components such as float, lifting plate, and submersible pump, it solves the problems of submersible pumps being directly thrown into the bottom of the sump, easily absorbing silt from the bottom of the sump; silt clogging the pump body flow channel, causing a sharp drop in pumping efficiency, aggravating wear on internal pump components, shortening equipment life, and increasing the frequency of shutdown for cleaning, thus affecting the construction progress.

[0006] (ii) Technical Solution

[0007] To achieve the above objectives, the present invention provides the following technical solution: a drainage device for building construction, comprising a lifting plate, a float ball fixedly installed on the upper surface of the lifting plate, a water inlet hole opened on the left side of the lifting plate, the other end of the water inlet hole being located on the lower surface of the lifting plate, and a water pipe installed on the left side of the lifting plate, the water pipe being connected to a drainage pipe.

[0008] A submersible pump is installed on the lower surface of the lifting plate, and a protective frame is installed on the lower surface of the lifting plate to prevent garbage from clogging the submersible pump. Two sets of symmetrical guide holes are opened on the upper surface of the lifting plate, and the lifting plate is equipped with a positioning guide mechanism.

[0009] Furthermore, the buoyancy of the float enables the device to float on the surface of the water, and the right end of the water supply pipe is connected to one end of the water supply hole.

[0010] Furthermore, the output end of the submersible pump is connected to one end of the water inlet, and the protective frame houses the submersible pump inside.

[0011] Furthermore, the positioning and guiding mechanism includes a connecting frame and two sets of mutually symmetrical guide rods, and the upper surface of the connecting frame is provided with two sets of mutually symmetrical through holes.

[0012] Furthermore, the bottom of the outer surface of the two sets of guide rods is fixedly connected to the inner sidewall of the two sets of through holes, and the outer surface of the two sets of guide rods is slidably connected to the inner sidewall of the two sets of guide holes.

[0013] Furthermore, both sets of guide rods have threaded holes at their top ends, and the inner walls of both sets of threaded holes are threaded with threaded rods.

[0014] Furthermore, a rotating disk is fixedly connected to the top of each of the two sets of threaded rods, and a ground nail is fixedly installed at the bottom of each of the two sets of threaded rods.

[0015] (iii) Beneficial effects:

[0016] Compared with existing technologies, this drainage device for building construction has the following advantages:

[0017] 1. The drainage device used in this construction project uses the buoyancy of a float to suspend the lifting plate above the water, keeping the submersible pump away from the silt at the bottom of the pit. This prevents the silt from clogging the pump body and accelerating component wear. At the same time, the positioning and guiding mechanism restricts the movement direction of the lifting plate through the sliding cooperation between the guide rod and the guide hole. Combined with the balance state adjusted by the threaded rod in the early stage, this ensures that the submersible pump maintains a stable pumping posture when the water level rises and falls. This not only ensures stable pumping efficiency but also extends the equipment life and reduces construction delays caused by equipment failure.

[0018] 2. The drainage device used in this construction project uses a protective frame to house the submersible pump, preventing garbage and gravel from entering the pump body and avoiding blockage of the flow channel. The positioning and guiding mechanism is maintained by the stable positioning and continuous balance of the ground nails, preventing the device from swaying with the water flow, which could cause the protective frame to shift or the protection to fail. This ensures that the anti-blocking function is continuously effective, reduces the frequency of downtime for cleaning the submersible pump, ensures the continuous progress of drainage operations, and avoids affecting the construction progress.

[0019] Third, this drainage device for construction uses ground nails to ensure stable positioning, preventing drift in waterlogged areas. Guide rods provide precise guidance for the lifting plate, preventing it from deviating from the optimal pumping area. The threaded rod adjusting the height of the connecting frame ensures the lifting plate is initially level, preventing uneven force on the submersible pump or poor pumping due to device tilt. This multi-functional synergy significantly improves the overall stability and adaptability of the device, solving the problems of easy deviation, difficulty adapting to water level changes, and unstable operation of existing devices, providing reliable assurance for drainage operations.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] The submersible pump 5 in this utility model is a common electrical device in the prior art, and this application will not elaborate on its model or internal structure.

[0029] like Figure 1-5 As shown, this utility model provides a technical solution: a drainage device for building construction, including a lifting plate 1, a float 2 fixedly installed on the upper surface of the lifting plate 1, a water inlet 3 opened on the left side of the lifting plate 1, the other end of the water inlet 3 being located on the lower surface of the lifting plate 1, a water pipe 4 installed on the left side of the lifting plate 1, the water pipe 4 being connected to a drainage pipe, a submersible pump 5 installed on the lower surface of the lifting plate 1, a protective frame 6 installed on the lower surface of the lifting plate 1 to prevent debris from clogging the submersible pump 5, two sets of mutually symmetrical guide holes 7 opened on the upper surface of the lifting plate 1, a positioning and guiding mechanism 8 provided on the lifting plate 1, the buoyancy of the float 2 enabling the device to float in the upper part of the water body, the right end of the water pipe 4 being connected to one end of the water inlet 3, the output end of the submersible pump 5 being connected to one end of the water inlet 3, and the protective frame 6 housing the submersible pump 5 inside.

[0030] After the device is placed in the construction sump or waterlogged area, the float 2 on the upper surface of the lifting plate 1 is driven by the buoyancy of the water to suspend the entire lifting plate 1 in the upper part of the water. As the water level in the construction area rises and falls, the float 2 will simultaneously drive the lifting plate 1 to slide up and down along the axial direction of the guide rod 802. During this process, the guide rod 802 strictly limits the movement direction of the lifting plate 1 to prevent it from deviating with the water flow and to continuously play a guiding role. At the same time, in conjunction with the balance state adjusted in the early stage, it ensures that the lifting plate 1 always maintains a stable posture, so that the submersible pump 5 installed on the lower surface of the lifting plate 1 is always in a suitable pumping position in the water, avoiding it from being exposed above the water surface or sinking to the bottom of the pit and contacting the silt. Then, the submersible pump 5 is started to pump out the accumulated water. After the submersible pump 5 sucks in the water, it delivers it to the water inlet 3 inside the lifting plate 1 through its output end. The water flows into the water pipe 4 on the left side of the lifting plate 1 through the water inlet 3 connected to the submersible pump 5, and then is discharged from the construction area through the connection between the water pipe 4 and the external drainage pipe. During this process, the protective frame 6 installed on the outside of the submersible pump 5 will prevent garbage, gravel and other debris carried by the accumulated water from entering the water inlet of the submersible pump 5, so as to avoid debris clogging the internal flow channel of the submersible pump 5. The positioning and guiding mechanism 8 provides a basic guarantee for the stable operation of the submersible pump 5 by continuously maintaining the positioning and balance of the device, and reducing the risk of equipment failure.

[0031] The positioning and guiding mechanism 8 includes a connecting frame 801 and two sets of symmetrical guide rods 802. The upper surface of the connecting frame 801 has two sets of symmetrical through holes 807. The bottom of the outer surface of the two sets of guide rods 802 is fixedly connected to the inner sidewall of the two sets of through holes 807, and the outer surface of the two sets of guide rods 802 is slidably connected to the inner sidewall of the two sets of guide holes 7. The top of each set of guide rods 802 has a threaded hole 803. The inner sidewall of each set of threaded holes 803 is threaded with a threaded rod 804. The top of each set of threaded rods 804 is fixedly connected to a rotating disk 805, and the bottom of each set of threaded rods 804 is fixedly installed with a ground nail 806.

[0032] When assembling the positioning and guiding mechanism 8, firstly, the connecting frame 801 is fixedly connected to the guide rod 802 through the through hole 807. Then, the rotating disk 805 is rotated to drive the threaded rod 804 to adjust its length in the threaded hole 803. This step can be achieved by adjusting the relative height of the connecting frame 801 and the ground to ensure that the lifting plate 1 is initially level, thus achieving the adjustment and balance function. Subsequently, the ground nail 806 is driven into the ground of the construction area to directly and firmly lock the positioning and guiding mechanism 8, achieving the positioning effect. At this time, the guide rod 802 is slidably connected to the guide hole 7 of the lifting plate 1, which not only completes the assembly of the lifting plate 1 and the positioning and guiding mechanism 8, but also presets the guide path for the subsequent movement of the lifting plate 1, thus initially demonstrating the guiding function.

[0033] Working principle: First, the device is installed and positioned. When assembling the positioning guide mechanism 8, the connecting frame 801 is first fixedly connected to the guide rod 802 through the through hole 807. Then, the rotating disk 805 is rotated to drive the threaded rod 804 to adjust its length in the threaded hole 803. This step can adjust the relative height of the connecting frame 801 and the ground to ensure that the lifting plate 1 is initially level, thus achieving the adjustment and balance function. Then, the ground nail 806 is driven into the ground of the construction area to directly form a stable lock on the positioning guide mechanism 8, achieving the positioning effect. At this time, the guide rod 802 is slidably connected to the guide hole 7 of the lifting plate 1, which not only completes the assembly of the lifting plate 1 and the positioning guide mechanism 8, but also presets the guide path for the subsequent movement of the lifting plate 1, initially demonstrating the guiding function. Next, water level adjustment is performed. After placing the device in the construction sump or water accumulation area, the float 2 on the upper surface of the lifting plate 1 is driven by the buoyancy of the water to suspend the entire lifting plate 1 in the upper part of the water. As the water level in the construction area rises and falls, the float 2 will synchronously drive the lifting plate 1 to slide up and down along the axial direction of the guide rod 802. During this process, the guide rod 802 strictly limits the movement direction of the lifting plate 1 to prevent it from deviating with the water flow and to continuously play a guiding role. At the same time, in conjunction with the balance state adjusted in the early stage, it ensures that the lifting plate 1 always maintains a stable posture, so that the submersible pump 5 installed on the lower surface of the lifting plate 1 is always in a suitable pumping position in the water, avoiding exposure to the water surface or sinking to the bottom of the pit and contacting the silt. Then, the submersible pump 5 is started to pump out the accumulated water. After the submersible pump 5 sucks in the water, it delivers it to the water inlet 3 inside the lifting plate 1 through its output end. The water flows into the water pipe 4 on the left side of the lifting plate 1 through the water inlet 3 connected to the submersible pump 5, and then is discharged from the construction area through the connection between the water pipe 4 and the external drainage pipe. During this process, the protective frame 6 installed on the outside of the submersible pump 5 will prevent garbage, gravel and other debris carried by the accumulated water from entering the water inlet of the submersible pump 5, so as to avoid debris clogging the internal flow channel of the submersible pump 5. The positioning and guiding mechanism 8 provides a basic guarantee for the stable operation of the submersible pump 5 by continuously maintaining the positioning and balance of the device, and reducing the risk of equipment failure.
