Description

Technical Field

[0001] This utility model relates to the field of water absorption equipment technology, specifically to a construction site water removal device for construction projects. Background Technology

[0002] During construction, it is often necessary to remove the accumulated water in the foundation pit before proceeding to the next step, especially for flat-bottomed pools and concrete pits. When the water pump reaches a certain water level, it is no longer possible to drain the remaining few centimeters of water. This is because self-priming water pumps operate under vacuum conditions in the pump pipe, using the vacuum negative pressure created by the pump's operation to force water below the pump outlet up under atmospheric pressure before discharging it from the pump. If the water level is too low, the pump outlet cannot be sealed to form a vacuum, so no matter how much water is pumped, it cannot be completely drained, causing many problems for the construction.

[0003] Chinese patent document CN 203716163 U discloses a ground water suction device, including a submersible pump and a suction cup. The top surface of the suction cup has a connecting hole, which is connected to the water inlet of the submersible pump through a connecting pipe. Water suction holes are distributed on the bottom surface of the suction cup, and side suction holes are distributed on the side. A cover is movably provided on the outer surface of the suction cup. By adding a suction cup to the bottom of the submersible pump, the bottom surface of the suction cup is in close contact with the ground of the water pit, making it easy to extract the remaining water with a low water level. When there is a relatively large amount of water, the cover on the outer surface of the suction cup is slid upward to expose the side suction holes on the side of the suction cup, thereby speeding up the water extraction. When there is a relatively small amount of water, the cover is slid downward to cover the water suction holes on the side of the suction cup, and the remaining water is extracted. This utility model has a simple structure and is easy to use.

[0004] Although the device disclosed above can suck up water, if the ground is too flat and the remaining water on the ground cannot submerge the side suction hole on the side of the suction cup, the cover needs to block the side suction hole and rely only on the water suction hole at the bottom to absorb the water. However, on a flat ground, the bottom surface of the suction cup is close to the ground, and water cannot enter the water suction hole. It can be seen that the device disclosed above is easily affected by the working environment.

[0005] Therefore, a construction site dewatering device is needed to solve the above problems. Utility Model Content

[0006] To address the aforementioned problems, namely the susceptibility of existing dewatering equipment to environmental influences, this invention provides a construction site dewatering device for construction projects.

[0007] A construction site water removal device includes a water storage tank. A roller is rotatably mounted on one side of the water storage tank, and absorbent cotton is fixedly mounted on the outer side of the roller. A squeezing roller is provided on one side of the water storage tank, and the squeezing roller abuts against the outer surface of the absorbent cotton. A water inlet hole is provided through the top wall of the water storage tank. A guide plate is fixedly mounted on the upper surface of the water storage tank. The guide plate is inclined, with the lower end of the guide plate located directly above the water inlet hole and the higher end of the guide plate located below the squeezing roller. By providing absorbent cotton on the outer side of the roller and having the squeezing roller abut against the outer surface of the absorbent cotton, the absorbent cotton absorbs water from the ground when the device is moved. The water inside the absorbent cotton is then squeezed out by the squeezing roller and flows into the water storage tank through the guide plate. Utilizing the elastic properties of the absorbent cotton, it can effectively absorb water on both flat surfaces and surfaces with small pits, improving the applicability of the device.

[0008] The above-mentioned construction site dewatering equipment for construction projects has extension rods symmetrically fixedly installed at both ends of one side of the water storage tank, and the two ends of the roller are respectively rotatably installed on the two extension rods.

[0009] The aforementioned construction site dewatering equipment includes an outer cylinder fixedly mounted on the upper surface of each of the two extension rods. An inner sliding rod is slidably mounted inside the outer cylinder via a pull-down spring. The top end of each inner sliding rod extends outside the outer cylinder. Both ends of the squeeze roller are rotatably mounted on the two inner sliding rods near their top ends. The distance between the higher end of the guide plate and the outer surface of the roller is equal to the thickness of the absorbent cotton. By slidably mounting the inner sliding rods inside the outer cylinder via pull-down springs, the squeeze roller can always press against the absorbent cotton and squeeze it. Furthermore, if solid particles adhere to the absorbent cotton, the sliding of the inner sliding rods provides some space for the squeeze roller to move, preventing damage to the absorbent cotton or the squeeze roller.

[0010] The aforementioned construction site dewatering equipment for construction projects includes a water storage tank with an installation groove on the lower surface near the extension rod. An installation rod is slidably installed inside the installation groove, and a receiving frame is fixedly installed at the end of the installation rod away from the water storage tank. The receiving frame is located directly below the roller and the water storage tank, with a perforated top and a drainage hole penetrating the bottom wall. By placing the receiving frame directly below the roller and the water storage tank, when large debris adheres to the outer surface of the absorbent cotton, the rotation of the roller scrapes the debris off upon contact with the bottom of the guide plate, causing it to fall into the receiving frame. This not only prevents the debris from damaging the extrusion roller and the absorbent cotton but also collects the debris.

[0011] The above-mentioned construction site dewatering equipment for construction projects has a rear roller installed on the bottom side of the water storage tank away from the drum via a roller frame. The bottom of the rear roller is at the same level as the bottom of the drum. The bottom of the receiving frame is higher than the bottom of the rear roller. A handle is fixedly installed on the upper surface of the water storage tank away from the drum. A threaded cap is threadedly installed on the side of the water storage tank near the bottom.

[0012] The beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides water-absorbing cotton on the outside of the roller and a squeezing roller against the outer surface of the water-absorbing cotton. When the device is pushed forward, the water-absorbing cotton absorbs water from the ground. Then, the water inside the water-absorbing cotton is squeezed out by the squeezing roller and flows into the water storage tank through the guide plate. Utilizing the elastic properties of the water-absorbing cotton, it can effectively absorb water on both flat and pitted surfaces, thus improving the applicability of the device.

[0014] 2. This utility model slidably installs the inner slide rod inside the outer cylinder via a pull-down spring, so that the squeezing roller can always press against the absorbent cotton and squeeze it. In addition, if solid particles stick to the absorbent cotton, the sliding of the inner slide rod can also give the squeezing roller some room to move, which can prevent the absorbent cotton or the squeezing roller from being damaged.

[0015] 3. This utility model provides a receiving frame directly below the roller and the water storage tank. When large debris sticks to the outer surface of the absorbent cotton, the rotating roller scrapes the debris off when it comes into contact with the bottom of the guide plate and falls into the receiving frame. This not only prevents the debris from damaging the extrusion roller and the absorbent cotton, but also collects the debris. Attached Figure Description

[0021] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0022] like Figure 1 As shown in the figure, this utility model discloses a construction site water removal device for construction projects, including a water storage tank 1. A roller 2 is rotatably installed on one side of the water storage tank 1, and absorbent cotton 3 is fixedly installed on the outer side of the roller 2. A squeezing roller 4 is provided on one side of the water storage tank 1, and the squeezing roller 4 abuts against the outer surface of the absorbent cotton 3. A water inlet hole 5 is opened through the top wall of the water storage tank 1. A guide plate 6 is fixedly installed on the upper surface of the water storage tank 1. The guide plate 6 is inclined, with the lower end of the guide plate 6 located directly above the water inlet hole 5 and the higher end of the guide plate 6 located below the squeezing roller 4. By providing absorbent cotton 3 on the outer side of the roller 2 and squeezing roller 4 abutting against the outer surface of the absorbent cotton 3, the absorbent cotton 3 absorbs water from the ground when the device is pushed to move. Then, the water in the absorbent cotton 3 is squeezed out by the squeezing roller 4 and flows into the water storage tank 1 through the guide plate 6. Utilizing the elastic properties of the absorbent cotton 3, it can effectively absorb water on both flat ground and ground with small pits, improving the applicability of the device.

[0023] like Figure 1 As shown, extension rods 7 are symmetrically fixedly installed at both ends of one side of the water storage tank 1, and the two ends of the roller 2 are respectively rotatably installed on the two extension rods 7.

[0024] like Figures 1-2 As shown, an outer cylinder 8 is fixedly installed on the upper surface of both extension rods 7. An inner slide rod 10 is slidably installed inside the outer cylinder 8 via a pull-down spring 9. The top end of the inner slide rod 10 extends outside the outer cylinder 8. The two ends of the squeeze roller 4 are respectively rotatably installed on the two inner slide rods 10 near the top. The distance between the higher end of the guide plate 6 and the outer surface of the roller 2 is equal to the thickness of the absorbent cotton 3. By sliding the inner slide rod 10 inside the outer cylinder 8 via the pull-down spring 9, the squeeze roller 4 can always press against the absorbent cotton 3 and squeeze it. In addition, if solid particles stick to the absorbent cotton 3, the sliding of the inner slide rod 10 can also give the squeeze roller 4 some room to move, which can prevent the absorbent cotton 3 or the squeeze roller 4 from being damaged.

[0025] like Figure 1 and Figure 3As shown, a mounting groove 11 is provided on the lower surface of the water storage tank 1 near the extension rod 7. A mounting rod 12 is slidably installed inside the mounting groove 11. A receiving frame 13 is fixedly installed at the end of the mounting rod 12 away from the water storage tank 1. The receiving frame 13 is located directly below the roller 2 and the water storage tank 1. The top of the receiving frame 13 is open, and a drain hole 14 is provided through the bottom wall of the receiving frame 13. By setting the receiving frame 13 directly below the roller 2 and the water storage tank 1, when large debris sticks to the outer surface of the absorbent cotton 3, the debris will be scraped off when it comes into contact with the bottom of the guide plate 6 due to the rotation of the roller 2, and then fall into the receiving frame 13. This not only prevents the debris from damaging the squeezing roller 4 and the absorbent cotton 3, but also collects the debris.

[0026] like Figure 1 As shown, a rear roller 15 is installed on the bottom of the water tank 1 away from the roller 2 via a roller frame. The bottom of the rear roller 15 is on the same horizontal plane as the bottom of the roller 2. The bottom of the receiving frame 13 is higher than the bottom of the rear roller 15. A handle 16 is fixedly installed on the upper surface of the water tank 1 away from the roller 2. A threaded cap 17 is threaded through the side of the water tank 1 near the bottom.
