[0002] Drainage devices for construction are equipment used for drainage treatment at construction sites. They are designed to drain rainwater, groundwater, wastewater, etc. generated at construction sites and ensure that the sites remain dry, clean and safe.
[0003] The drainage device used in construction in the prior art does not have the function of automatic dredging, and the debris net on the drain outlet is easily blocked by debris in the external environment, such as leaves, plastic bags, etc., resulting in the water being unable to be discharged smoothly. This blockage will cause the drainage device to lose its normal drainage function. Once the debris net is blocked, the water cannot pass through the drain outlet smoothly, and the drainage efficiency will be significantly reduced, which may cause water to accumulate around the building, increasing the risk of flooding inside the building and the surrounding environment, and even causing damage to the building structure and foundation.
[0004] Therefore, it is necessary to design a drainage device for building construction to solve the above problems. Utility Model Content

[0008] As a preferred technical solution of the utility model, the sliding assembly includes four connecting plates, four guide rods and four limit caps, the four connecting plates are respectively fixed at the four corners of the second grid plate, the four guide rods are all fixed on the drainage groove, the four connecting plates are respectively slidably mounted on the four guide rods, and the four limit caps are respectively fixed on the top ends of the four guide rods.
[0009] As a preferred technical solution of the utility model, the floating assembly includes two side plates and two float bags, the two side plates are respectively fixed on both sides of the second grid plate, and the two float bags are respectively arranged on the top surfaces of the two side plates.
[0010] As a preferred technical solution of the present invention, the shape of the first grid plate is adapted to the shape of the drainage groove, and the first grid plate is the same size as the second grid plate.
[0011] As a preferred technical solution of the utility model, a through hole matched with the guide rod is opened on the connecting plate, and the cross-sectional diameter of the limiting cap is larger than the diameter of the through hole.
[0012] As a preferred technical solution of the utility model, the floating bag is made of rubber material.
[0013] The utility model has the following beneficial effects:
[0014] 1. Automatic dredging function: When the second grid plate is blocked by debris, water cannot flow through, but as the water level gradually rises, the float floats on the water surface under the action of buoyancy, so that the second grid plate moves upward with the float, separating the drainage port and achieving automatic dredging. This design avoids manual intervention and improves the automation of the drainage device.
[0015] 2. Prevent water level from rising: Due to the automatic movement of the second grid plate, the drain can be opened in time, and the water can flow smoothly into the drainage device, avoiding the continuous rise of the water level. This helps prevent the accumulation of water around the building and reduces the risk of flooding.
[0016] 3. Reduce maintenance frequency: Since the drainage device has an automatic dredging function, there is no need for frequent manual cleaning and maintenance. This reduces the frequency and cost of maintenance and reduces the investment in human resources.
[0017] 4.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.
[0023] Reference Figure 1-3 A drainage device for construction, comprising a drainage trough 1, the drainage trough 1 is connected with a drainage pipe 2, the drainage trough 1 is provided with a first grid plate 3, a movable second grid plate 4 is provided above the first grid plate 3, the shape of the first grid plate 3 is adapted to the shape of the drainage trough 1, the first grid plate 3 and the second grid plate 4 are of the same size, the second grid plate 4 is connected to the drainage trough 1 through a sliding assembly, the sliding assembly comprises four connecting plates 51, four guide rods 52 and four limiting caps 53, the four connecting plates 51 are respectively fixed at the four corners of the second grid plate 4, the four guide rods 52 are all fixed on the drainage trough 1, the four connecting plates 51 are respectively slidably sleeved on the four guide rods 52, the connecting plates 51 are provided with through openings adapted to the guide rods 52, the cross-sectional diameter of the limiting caps 53 is larger than the diameter of the through opening, the four limiting caps 53 are respectively fixed to the top ends of the four guide rods 52, the second grid plate 4 is movable During the movement, the four connecting plates 51 and the four guide rods 52 limit the movement of the second grid plate 4 to ensure the stability of the movement of the second grid plate 4. In addition, the four limiting caps 53 can prevent the four connecting plates 51 from falling off the four guide rods 52. A floating assembly is provided on the second grid plate 4, and the floating assembly includes two side plates 61 and two float bags 62. The two side plates 61 are respectively fixed on both sides of the second grid plate 4, and the two float bags 62 are respectively arranged on the top surfaces of the two side plates 61. The float bags 62 are made of rubber material. When the water level rises, the two float bags 62 on the second grid plate 4 will float on the water surface under the action of buoyancy, which makes the second grid plate 4 move upward with the two float bags 62. When the second grid plate 4 moves upward, the second grid plate 4 will be separated from the drainage trough 1. At this time, the water flow can flow into the interior of the drainage trough 1 through the bottom of the second grid plate 4 to avoid continuous accumulation of water flow.
[0024] The specific working principle of the utility model is as follows:
[0025] When the drainage device for construction proposed by the utility model is used, in the initial state, under the action of gravity, the second grid plate 4 is placed on the first grid plate 3. When the second grid plate 4 is blocked by debris, the water flow cannot pass through the second grid plate 4 to enter the interior of the drainage groove 1. At this time, the water flow will accumulate, which makes the water level near the drainage groove 1 gradually rise. When the water level rises, the two floats 62 on the second grid plate 4 will float on the water surface under the action of buoyancy, which makes the second grid plate 4 move upward with the two floats 62. When the second grid plate 4 moves upward, the second grid plate 4 will separate from the drainage groove 1. At this time, the water flow can flow into the interior of the drainage groove 1 through the bottom of the second grid plate 4, avoiding continuous accumulation of water flow, restoring the drainage function of the drainage groove 1, and realizing the automatic dredging function of the drainage groove 1.
[0026] When the second grid plate 4 is moving, the four connecting plates 51 and the four guide rods 52 limit the movement of the second grid plate 4 to ensure the stability of the movement of the second grid plate 4. In addition, the four limiting caps 53 can prevent the four connecting plates 51 from falling off the four guide rods 52. It should be noted that the second grid plate 4 is made of lightweight materials such as plastic, which facilitates the second grid plate 4 to move upward following the two floats 62.
[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
