Description

Technical Field

[0001] The utility model belongs to the technical field of building construction, and in particular relates to temporary drainage equipment used in building construction. Background Art

[0002] At the construction site, temporary drainage equipment needs to be set up to drain rainwater and construction water out of the construction site to create a good construction environment.

[0003] For example, CN219794145U discloses a temporary drainage device for a construction site, which includes a drainage trough plate, a drainage grate plate clamped on the drainage trough plate, and a mud and sand cleaning assembly arranged on the drainage trough plate; the mud and sand cleaning assembly includes an arc plate detachably arranged on the drainage trough plate and at least one vertical pole arranged on the arc plate; the arc plate completely covers the inner wall of the drainage trough plate.

[0004] Although the above scheme can complete the cleaning of the intercepted sediment by disassembling the sediment cleaning component, it is very easy to cause blockage during drainage, especially when a large amount of construction water is drained. Once blocked, overflow, water accumulation, etc. will occur, and the drainage function will be hindered, requiring high-frequency cleaning of the cleaning component. Utility Model Content

[0005] In view of the deficiencies and difficulties in the prior art, the utility model aims to provide a temporary drainage device for building construction.

[0006] The utility model is implemented through the following technical solutions:

[0008] The water filter screen frame and the water transfer tank are installed in a non-fixed, detachable and separate manner. Specifically, one end of the water filter screen frame is connected to the side wall of the water transfer tank through a filter screen installation assembly. The filter screen installation assembly includes a limiting support fixed to the side wall of the water transfer tank, a clamping piece that is concavely connected to the limiting support piece, and a hinge that connects the clamping piece to one end of the water filter screen frame.

[0009] Furthermore, in a specific implementation, the angle a at which the water filter frame is inclined relative to the vertical surface of the water tank is 5-30 degrees.

[0010] Furthermore, each group of water filter frames are arranged parallel to each other.

[0011] Furthermore, the water inlet end of the water transfer tank adopts an arc structure, and the water inlet groove is tangentially connected to the inlet of the water transfer tank, so that a tangential flow is formed when the wastewater enters the water transfer tank.

[0012] Furthermore, an opening is provided at the upper part of the water tank, and the opening covers the area where each group of water filter frames are installed, and a groove plate is arranged at the opening; an extension cylinder extending upward is installed at the periphery of the opening.

[0025] In order to make the purpose, technical solution and beneficial effects of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0026] In the description of the present invention, unless otherwise clearly specified and limited, the terms "connected", "connected", and "fixed" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0027] In the description of this embodiment, terms such as "up", "down", "right", and "left" and other directions or positional relationships are based on the relationships shown in the accompanying drawings and are only for the convenience of description and simplification of operation. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present utility model.

[0028] In order to illustrate the technical solution of the present invention, specific embodiments are provided below for illustration.

[0029] like Figures 1 to 3 As shown, a temporary drainage device for construction includes a water tank 1, a plurality of groups of water filter frames 3 installed inside the water tank 1 and arranged in a staggered manner, a water inlet trough 6 arranged at one end of the inlet of the water tank 1, and a water outlet pipe 4 at one end of the outlet, wherein the plurality of groups of water filter frames 3 are staggered in sequence inside the water tank 1 to form an S-shaped water flow channel. When wastewater from construction enters the water tank 1 through the water inlet trough 6, the wastewater is first filtered by each group of water filter frames 3, and the excess wastewater flows through the S-shaped water flow channel. Each group of water filter frames 3 intercepts in steps, and granular soil, gravel and other wastes can be separated from water without affecting the rapid flow of the water body. Even if part of the water filter frames 3 are blocked, the drainage is not affected at all.

[0030] The water filter net frame 3 and the water tank 1 are installed in a non-fixed, detachable and separable manner. Specifically, one end of the water filter net frame 3 is connected to the side wall of the water tank 1 through the filter screen installation assembly 2. The filter screen installation assembly 2 includes a limit support 10 fixed to the side wall of the water tank 1, a clamping member 11 connected to the limit support 10 in a concave-convex manner, and a hinge 12 connecting the clamping member 11 to one end of the water filter net frame 3. The clamping member 11 is connected to the limit support 10 in a concave-convex manner so that the two can be assembled and separated. For example, the limit support 10 is provided with a linear groove, and the clamping member 11 is provided with a convex slider. The slider is embedded in the linear groove so that the clamping member 11 is connected to the limit support 10, and the slider slides out of the linear groove so that the clamping member 11 is separated from the limit support 10. The setting of the hinge 12 makes the setting angle of the water filter net frame 3 adjustable, thereby making the water filter net frame 3 tilted relative to the vertical surface of the water tank 1. The inclined water filter frame 3 can also play a certain role in drainage. In a specific implementation, the angle a of the water filter frame 3 relative to the vertical surface of the water tank 1 is 5-30 degrees. And each group of water filter frames 3 is arranged parallel to each other. In a specific implementation, the hinge 12 is also equipped with a self-locking structure. When the water filter frame 3 is set to a corresponding angle, the self-locking structure fixes the water filter frame 3. The self-locking structure adopts the conventional locking setting of the hinge mechanism. Its structure, composition, installation and connection all adopt the existing technology, which will not be elaborated in detail here.

[0031] The water inlet end of the water tank 1 adopts an arc structure (such as a semi-cylindrical structure), and the water inlet groove 6 is tangentially connected to the inlet of the water tank 1, so that the wastewater forms a tangential flow when entering the water tank 1. Compared with the conventional water inlet method, the water inlet of the utility model flows in a tangential spiral shape, which is more conducive to efficient water flow.

[0032] The upper part of the water tank 1 is provided with an opening, which covers the area where each group of water filter net frames 3 are installed, and a slot plate 7 is arranged at the opening; an extension cylinder 8 extending upward is installed on the periphery of the opening. The slot plate 7 and the extension cylinder 8 are used to prevent excessive squeezing of the drainage device when the water volume is too large; the slot plate 7 has a large number of slots, and when the water volume exceeds the load of the water tank 1, the extension cylinder 8 intercepts the excess wastewater to prevent it from overflowing.

[0033] Several groups of supporting legs 9 are provided at the bottom of the water tank 1 for support. The water outlet pipe 4 is fixedly connected to the bottom of the outlet end of the water tank 1. The water outlet pipe 4 is fixedly connected to the corrugated connecting pipe 5 through flanges and other connecting parts. The corrugated connecting pipe 5 can be stretched or contracted, and then the outlet of the corrugated connecting pipe 5 can be connected to the corresponding drainage area (such as a municipal drainage outlet) as needed.

[0034] The sidewalls of the inlet and outlet of the water tank 1 are all set to be inclined planes, which are equivalent to guide plates and are more conducive to the flow of water. In addition, the joints of each surface of the water tank 1 are smooth arc chamfers, which can prevent pollutants from sticking and remaining in dead corners.

[0035] The above only expresses the preferred implementation of the utility model, and its description is relatively specific and detailed, but it cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, without departing from the concept of the utility model, several modifications, improvements and substitutions can be made, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
