Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and in particular to drainage devices for building engineering. Background Technology

[0002] Construction refers to the production activities during the implementation phase of a project. It is the process of building various types of buildings, or the process of turning the lines on the design drawings into physical objects at designated locations. It includes foundation construction, main structure construction, roof construction, decoration construction, etc. The place where construction work is carried out is called the "construction site" or "construction site". When it rains during construction, water will accumulate in some construction locations, and drainage devices will be needed to drain the water.

[0003] During the use of existing drainage systems for building construction, workers need to change the location of the drainage system because the water accumulation location is different. Furthermore, for some drainage systems with long pipes, it is inconvenient to retract the pipes after they have been laid out and drained. An existing patent (publication number: CN222612635U) discloses a drainage device for building engineering. This utility model uses self-locking universal wheels on the bottom of the base plate and a handle to drive the overall movement of the device. When used in different positions, a battery powers the drainage pump, which then drains water from the required drainage area through the drainage pump and suction pipe and discharges it through the drainage pipe. After the drainage operation is completed, a manual turntable drives the collection roller to rotate and retract the drainage pipe. During the retraction, the distance between the two extrusion rollers is adjusted according to the size of the drainage pipe. The extrusion rollers squeeze the drainage pipe to remove residual water and improve the collection efficiency of the drainage pipe.

[0004] To address the aforementioned issues, existing patents offer solutions, but the proposed building drainage devices have significant shortcomings: the suction pipe matched with the drainage pump is merely a single tubular structure without a filtration system. Meanwhile, the stagnant water in construction areas contains a mixture of various impurities such as leaves, debris, mud, gravel, and concrete residue. These unfiltered impurities can cause multiple problems: they easily clog the suction pipe, reducing drainage efficiency and requiring frequent manual cleaning; they can also enter the drainage pump with the water flow, wearing down the impeller, damaging seals, depositing sediment in the pump chamber, shortening equipment lifespan, and even causing motor burnout; furthermore, they may clog municipal pipe networks, pollute the soil, or damage downstream equipment, creating a chain of hidden dangers. This is severely inconsistent with the efficient and reliable drainage requirements of building projects.

[0005] Therefore, a drainage device for building engineering is proposed. Utility Model Content

[0006] The purpose of this utility model is to provide a drainage device for building engineering, which can solve the obvious shortcomings of the drainage devices for building engineering proposed in the above-mentioned patents: the suction pipe matched with the drainage pump is only a single tubular structure and is not equipped with a filter structure. The water in the construction area of ​​the building engineering is mixed with a variety of impurities such as leaves, debris, mud, gravel, and concrete residue. Unfiltered impurities will cause multiple problems. They can easily clog the suction pipe, resulting in a decrease in drainage efficiency and requiring frequent manual cleaning. They can also enter the drainage pump with the water flow, wear the impeller, damage the seals, and deposit in the pump chamber, shorten the equipment life and even cause the motor to burn out. They may also be discharged with the drainage, blocking the municipal pipe network, polluting the soil, or damaging subsequent equipment, forming a chain of hidden dangers. This is seriously inconsistent with the efficient and reliable drainage requirements of building engineering.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a building engineering drainage device, including a movable plate, a controller is provided on the rear side of the top of the movable plate, and a drainage component and a power supply structure are respectively provided on the top of the movable plate; The drainage assembly includes a drainage pump located on the rear side of the top of the movable plate.

[0018] 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.

[0019] Please see Figure 1-5 The present invention provides the following technical solution: The building drainage device includes a movable plate 1, a controller 2 is provided on the rear side of the top of the movable plate 1, and a drainage component 3 and a power supply structure 4 are respectively provided on the top of the movable plate 1. The drainage assembly 3 includes a drainage pump 301 located on the rear side of the top of the movable plate 1. The drainage pump 301 is electrically connected to the controller 2. The output end and the absorption end of the drainage pump 301 are respectively connected to a drainage pipe 302 and a connecting pipe 303. A guide structure 304 and a pressure-guiding structure 305 are respectively provided on the front side of the top of the movable plate 1. A receiving roller 306 is provided in the middle of the top of the movable plate 1. A water suction pipe 307 is wound around the outer side of the receiving roller 306. The water suction pipe 307 is connected to the connecting pipe 303. The front side of the water suction pipe 307 passes through the interior of the guide structure 304 and the pressure-guiding structure 305 in sequence. An internal threaded sleeve 308 is fixedly connected to the front side of the surface of the water suction pipe 307. A mesh cover cylinder 309 is threadedly connected to the bottom of the internal threaded sleeve 308. The mesh cover cylinder 309 is located outside the water inlet end of the water suction pipe 307.

[0020] In this embodiment: by setting up a moving plate 1, a controller 2, a drainage component 3, and a power supply structure 4, the power supply structure 4 provides stable power support to the controller 2 and the drainage pump 301, ensuring that the equipment can start normally. Then, the operator stretches the suction pipe 307, which moves smoothly along the guide structure 304, passes through the inside of the pressure guide structure 305, and is gradually released from the receiving roller 306 until the suction end of the suction pipe 307, together with the outer mesh cover 309, is placed in the area of ​​the building project that needs drainage. Then, the controller 2 starts the drainage pump 301. The drainage pump 301 forms a negative pressure suction passage with the suction pipe 307 through the connecting pipe 303. At this time, the mesh cover 309 at the water inlet end of the suction pipe 307 will first filter the leaves, debris, gravel and other impurities in the water, effectively preventing impurities from entering the inside of the suction pipe 307 or impacting the drainage pump 301 with the water flow. 01. To prevent blockage of the suction pipe 307 and damage to the drainage pump 301, the filtered water enters the drainage pump 301 through the suction pipe 307 and connecting pipe 303. After being pressurized by the drainage pump 301, it is discharged to the designated area through the drainage pipe 302. When the drainage operation is completed and the suction pipe 307 needs to be wound up, the suction pipe 307 is wound up and stored by the storage roller 306. During the winding process, the guide structure 304 continuously provides guidance for the suction pipe 307 to prevent it from deviating and getting stuck. The winding and releasing pressure guiding structure 305 assists in the smooth winding of the suction pipe 307 and can adjust the squeezing intensity to squeeze out the residual sewage in the suction pipe 307, reduce the weight of the suction pipe 307 and prevent sewage from dripping and polluting the working environment. The whole process is coordinated and controlled by the controller 2 to achieve efficient and stable drainage of water in the construction area, while ensuring the long-term reliable operation of the equipment.

[0021] Specifically, such as Figure 3 As shown, the retractable pressure guiding structure 305 includes a support rod 3051 bolted to the front side of the top of the movable plate 1, and a lifting groove 3052 is provided on the right side of the support rod 3051.

[0022] Specifically, such as Figure 3 As shown, an electric push rod 3053 is bolted to the top of the support rod 3051. The telescopic end of the electric push rod 3053 passes through the top of the support rod 3051. A lifting block 3054 is fixedly connected to the telescopic end of the electric push rod 3053. The lifting block 3054 is slidably connected inside the lifting groove 3052.

[0023] Specifically, such as Figure 3 As shown, an outwardly protruding pressure roller 3055 is rotatably connected to the right side of the lifting block 3054. The outwardly protruding pressure roller 3055 is located at the top of the water suction pipe 307. An inwardly concave conveying roller 3056 is rotatably connected to the bottom right side of the support rod 3051. The inwardly concave conveying roller 3056 is located at the bottom of the water suction pipe 307.

[0024] In this embodiment: by setting up the retraction and pressure guiding structure 305, the support rod 3051 provides the installation foundation for the overall structure, and the lifting groove 3052 on its right side provides sliding space for the lifting block 3054. When the electric push rod 3053 at the top of the support rod 3051 extends and retracts, it can drive the lifting block 3054 to move up and down along the lifting groove 3052, thereby adjusting the height of the right-side convex pressure roller 3055. When the suction pipe 307 is retracted, the bottom is supported by the concave conveying roller 3056, and the top is squeezed by the convex pressure roller 3055. When the pipe is released, the electric push rod 3053 controls the convex pressure roller 3055 to move upward, reducing the pressure on the suction pipe 307 and facilitating the smooth release of the suction pipe 307. When the pipe is retracted, the electric push rod 3053 drives the convex pressure roller 3055 to move downward, cooperating with the concave conveying roller 3056 to squeeze the suction pipe 307. This can not only assist the suction pipe 307 to be stably wound, but also squeeze out the residual sewage in the pipe, improving the winding efficiency and cleanliness.

[0025] Specifically, such as Figure 4 As shown, the guide structure 304 includes a fixed plate 3041 bolted to the front top of the movable plate 1, and a vertical rod 3042 is welded to the top of the fixed plate 3041.

[0026] Specifically, such as Figure 4 As shown, a guide sleeve 3043 is welded to the top of the upright 3042, and an auxiliary rotating ball 3044 is rotatably connected inside the guide sleeve 3043. The inner side of the auxiliary rotating ball 3044 contacts the outer side of the water suction pipe 307.

[0027] In this embodiment: by setting a guide structure 304, the fixing plate 3041 and the upright 3042 provide stable support for the guide sleeve 3043, ensuring that the guide sleeve 3043 is fixed in position. When the water suction pipe 307 is extended or retracted, it needs to pass through the inside of the guide sleeve 3043. The auxiliary rotating ball 3044 on the inner side of the guide sleeve 3043 contacts the outer side of the water suction pipe 307, converting the sliding friction between the water suction pipe 307 and the guide sleeve 3043 into rolling friction, greatly reducing frictional resistance and preventing the water suction pipe 307 from being damaged or stuck due to friction. At the same time, the guide sleeve 3043 can restrict the movement direction of the water suction pipe 307, preventing the water suction pipe 307 from deviating or tangling when extended or retracted, and ensuring that the water suction pipe 307 always moves smoothly along the preset path.

[0028] Specifically, such as Figure 5 As shown, the power supply structure 4 includes a box 401 located on the rear side of the top of the movable plate 1. A storage battery 402 is installed inside the box 401, and the storage battery 402 is electrically connected to the controller 2.

[0029] Specifically, such as Figure 5 As shown, a charging interface 403 and a discharging interface 404 are embedded in the left side of the box 401, and both the charging interface 403 and the discharging interface 404 are electrically connected to the battery 402.

[0030] In this embodiment: By setting up the power supply structure 4, the box 401 provides protection for the internal battery 402, preventing the battery 402 from being affected by dust and water accumulation at the construction site. The battery 402 is electrically connected to the controller 2, and can directly power the controller 2 and associated components such as the drainage pump 301 and electric push rod 3053 without relying on an external power source, adapting to scenarios where there is no fixed power supply on site, improving the mobility of the device. The charging interface 403 on the left side of the box 401 facilitates the replenishment of power to the battery 402, ensuring continuous operation of the device. The discharge interface 404 can power other small devices in emergencies, further enhancing the practicality of the device and ensuring the stable operation of drainage work.

[0031] Working principle: During the use of the drainage device in the building project, the operator first checks the power of the battery 402 in the power supply structure 4. If the power is insufficient, the battery 402 is replenished through the charging interface 403 on the left side of the box 401. After the power is sufficient, the device can be flexibly moved to the area of ​​the building project that needs drainage by relying on the movable plate 1, without relying on an external power source, which is suitable for scenarios where there is no fixed power supply on site. Then the operator begins to prepare for the drainage operation: first, the suction pipe 307 is stretched. The suction pipe 307 is gradually released from the receiving roller 306. During the process, it needs to pass through the guide sleeve 3043 of the guide structure 304. The fixed plate 3041 and the upright 3042 provide stable support for the guide sleeve 3043. The auxiliary rotating ball 3044 inside the guide sleeve 3043 and the suction... The outer side of the water pipe 307 contacts the outside, converting sliding friction into rolling friction, significantly reducing resistance. Simultaneously, it restricts the movement direction of the suction pipe 307, preventing it from deviating or tangling, ensuring the suction pipe 307 moves smoothly along the preset path. As the suction pipe 307 continues to pass through the release and retraction pressure guide structure 305, the electric push rod 3053 at the top of the support rod 3051 is activated, driving the lifting block 3054 upwards along the lifting groove 3052. This moves the outer convex pressure roller 3055 away from the bottom concave conveying roller 3056, reducing the pressure on the suction pipe 307 and facilitating its smooth release until the suction end of the suction pipe 307, along with the outer mesh sleeve 309, is placed into the water accumulation area. Then, the drain pump 301 is activated via the controller 2 at the rear top of the moving plate 1. The battery 402 provides... Controller 2 provides stable power support to drainage pump 301. After drainage pump 301 starts operating, it forms a negative pressure suction passage with suction pipe 307 through connecting pipe 303. The accumulated water flows towards the inlet end of suction pipe 307. At this time, the mesh sleeve 309 will first filter impurities such as leaves, debris, and gravel in the accumulated water, effectively preventing impurities from entering the inside of suction pipe 307 or impacting drainage pump 301, thus avoiding blockage of suction pipe 307 and damage to drainage pump 301. The filtered accumulated water enters drainage pump 301 through suction pipe 307 and connecting pipe 303, and is then pressurized by drainage pump 301 and discharged to the designated area through drainage pipe 302. After the drainage operation is completed, suction pipe 307 needs to be wound up: the operator controls the winding roller 306 to wind up suction pipe 307. During the process, the guide structure 304 continuously guides the suction pipe 307 to prevent jamming; at the same time, the controller 2 regulates the electric push rod 3053 of the retracting and releasing pressure guiding structure 305, driving the lifting block 3054 to move down along the lifting groove 3052, so that the outer convex pressure roller 3055 approaches the inner concave conveying roller 3056. The two work together to squeeze the suction pipe 307, which can not only help the suction pipe 307 to be stably wound, but also squeeze out the residual sewage in the pipe, reduce the weight of the suction pipe 307 and prevent sewage from dripping and polluting the working environment. The entire process is coordinated by the controller 2 to achieve efficient and stable drainage of water accumulated in the construction area. If other small equipment on site needs temporary power supply, emergency power can also be supplied through the discharge interface 404 on the left side of the box 401, further improving the practicality of the device.

[0032] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
