Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of construction drainage devices, specifically to a portable concrete sump water drainage device. Background Technology
[0002] The concrete gravity dam project, which includes pumps, power stations and other structures, is complex in structure and has many construction sites. Due to different construction progress, the height difference between the various work sites is different. Each site is basically a large volume of concrete, which requires water cooling to reduce the temperature difference between the inside and outside of the concrete, and frequent surface water spraying for curing.
[0003] Water generated during concrete curing and surface washing flows downwards under gravity and enters the construction surface at a lower elevation. The total amount of this water flow is not large, and the resulting water accumulation in the construction area often cannot be drained by gravity.
[0004] During the preparation of drainage silos, workers often manually use hand-held electric picks to chisel trenches inside the silo, allowing the accumulated water to drain out along these trenches. However, for pump and power station structures with large areas, where drainage is not feasible, especially in silo surfaces under construction with surface reinforcement, workers must use hand-held ladles and absorbent cloths, along with buckets, to painstakingly drain the water bit by bit. This drainage method is extremely inefficient, time-consuming, and significantly increases the workload. Furthermore, because the total amount of water accumulated in these silo flows is relatively small, traditional water pumps cannot meet their drainage needs. Utility Model Content

[0027] Example 1
[0028] Combined with appendix Figure 1-7 A portable concrete silo drainage device includes a housing 1. Inside the housing 1 are an internal wiring layer 14, a power cord storage compartment 12, an accessory storage compartment 15, a built-in battery area 9, and a water pump working area. The water pump working area occupies one side of the housing 1, while the other side is occupied by the built-in battery area and shared by the internal wiring layer 14, the power cord storage compartment 12, and the accessory storage compartment 15. The internal wiring layer 14 and the power cord storage compartment 12 are located above the accessory storage compartment 15. The power cord storage compartment 12 is located on one side of the internal wiring layer 14. The internal wiring layer 14 is used for internal wiring connections and occupies a larger area than the power cord storage compartment 12. The power cord storage compartment 12 contains an external power cord 11 and is used to store the external power cord 11. A built-in small self-priming pump 10 is fixedly installed in the water pump working area.
[0029] The internal wiring layer 14, power cord storage compartment 12, accessory storage compartment 15, built-in battery area 9, and water pump working area are separated by a partition 13 to prevent dirt from contaminating each other during use.
[0030] The outer casing 1 has a water pump control switch 3, an indicator light, and a built-in battery switch 4 on the top of the internal circuit layer 14. The water pump control switch 3 is used to control the water pump to turn on and off. The water pump control switch 3 controls the switch of the built-in small self-priming pump 10. The built-in battery switch 4 controls the switch of the built-in battery 9. The indicator light indicates the switch status of the built-in small self-priming pump 10 and the built-in battery 9, which is convenient for workers to judge.
[0031] The built-in battery area is equipped with a built-in battery 9, and the built-in battery area is also equipped with a power display screen 5 on the top of the outer casing 1. The power display screen 5 is electrically connected to the built-in battery 9, and the built-in battery 9 displays the remaining power of the built-in battery 9. The built-in battery 9 can be charged by an external power cord 11.
[0032] The internal wiring layer 14 contains wiring that electrically connects the water pump control switch 3, indicator lights, built-in battery switch 4, built-in battery 9, and built-in small self-priming pump 10.
[0033] The built-in mini self-priming pump 10 has an inlet 6 and an outlet 7 extending out of the outer casing 1 at both ends. The inlet 6 and outlet 7 are used to connect external pipes to the built-in mini self-priming pump 10.
[0034] The accessory storage compartment 15 contains accessories for the convenient use of the water drainage device. The accessories are: PVC hose 18, PVC hose detachable end 16, adjustable plastic buckle 17, and portable foldable bucket 19.
[0035] The PVC hose 18 is used to connect the inlet 6 and the outlet 7. The PVC hose 18 makes it easy for workers to place the pipe in the water accumulation position and is easy to use with the built-in small self-priming pump 1.
[0036] The detachable end 16 of the PVC hose is used to install on the PVC hose 18. The detachable end 16 of the PVC hose has a double-layer structure. The outer layer of the detachable end 16 of the PVC hose is a plastic shell with large filter holes. The inner layer is a small-diameter filter screen. After the built-in small self-priming pump 10 is turned on, the detachable end 16 of the PVC hose filters the water drawn into the PVC hose 18 to prevent impurities from entering the pipe and damaging the equipment.
[0037] The adjustable plastic clip 17 has a double-ring structure, consisting of a PVC hose end and a reinforcing bar end. The PVC hose end of the adjustable plastic clip 17 is fixed to the PVC hose 18, while the reinforcing bar end is a movable clip with an adjustment function. Tightening the bolt reduces the size of the reinforcing bar end. After fixing the PVC hose end to the PVC hose 18, placing the PVC hose 18 and the detachable end 16 of the PVC hose in the water suction position, and fixing the reinforcing bar end to a nearby reinforcing bar, maintains the position of the PVC hose 18 and the detachable end 16, allowing for continuous water suction without the need for continuous hand-holding by the worker.
[0038] A portable foldable water bucket 19 is placed on one side of the water outlet 7, which makes it convenient to store the water sucked up by the built-in small self-priming pump 10 in the portable foldable water bucket 19, which is convenient to use when the water outlet 7 cannot be connected to an external water pipe.
[0039] The outer casing 1 is still equipped with a handle 2 to facilitate workers moving the equipment.
[0040] The specific usage method is as follows:
[0041] As needed for construction, the device is manually transported to the work location using the external handle 2. After verification, the built-in battery switch 4 is turned on, and the power level of the built-in battery 9 can be viewed in real time via the power display screen 5.
[0042] Open the accessory storage compartment 15 and take out the corresponding accessories. Install the detachable end 16 of the PVC hose onto one end of the PVC hose 18 and place it in the water. Connect the other end of the PVC hose 18 to the water inlet 7.
[0043] One end of the adjustable plastic buckle 17 is fitted onto the PVC hose 18. After sliding to the appropriate position, the other end is connected to the steel bars inside the silo to fix the PVC hose 18 in place. Alternatively, the PVC hose can be manually held directly for operation.
[0044] Water accumulated inside the warehouse is discharged through outlet 7. Depending on the construction site conditions, it can be collected directly by a portable foldable bucket 19 or drained to the outside by connecting a PVC hose 18.
[0045] Once everything is ready, turn on the water pump control switch 3. The built-in battery 9 powers the built-in small self-priming pump 10. The water in the tank is discharged outside the site via the detachable end of the PVC hose 16 → PVC hose 18 → inlet 6 → built-in small self-priming pump 10 → outlet 7 → portable foldable bucket 19 / PVC hose 18.
[0046] After completing the task, turn off the water pump control switch 3 and the built-in battery switch 4, release the lock of the adjustable plastic buckle 17, remove the detachable ends 16 and 17 of the PVC hose and other accessories such as the adjustable plastic buckles, and clean them; coil the PVC hose 18, drain the water inside, and put it back into the accessory storage compartment 15.
[0047] When the power display screen 5 shows that the remaining power of the built-in battery 9 is low, the built-in battery switch 4 can be turned off, the external power cord 11 can be taken out from the power cord storage compartment 12, and connected to the on-site construction power supply to directly power the equipment to operate, while charging the built-in battery 9.
[0048] The equipment has multiple detachable windows on its outer casing. During maintenance, the corresponding window on the detachable casing can be opened to repair and maintain various parts.
