Description

Technical Field

[0001] The utility model relates to the technical field of drainage equipment, in particular to an adaptive gravity-balanced hidden drainage ditch cover. Background Art

[0002] Drainage is a very important design element in traditional hard-paved areas such as building roofs, courtyards, and squares. An effective drainage system has become an important part of maintaining the urban environment and protecting the lives of citizens.

[0003] Traditional drainage systems usually use fixed gutter covers. Although this design meets the basic drainage needs to a certain extent, it often ignores the coordination with the surrounding environment, resulting in a decrease in the beauty of the urban landscape. Even if the gap-type gutter is used, there are still many obvious wide gaps on the site, affecting the overall aesthetics. Especially in some high-end residential areas, commercial blocks or historical and cultural areas, there are high requirements for the overall landscape effect, especially the pattern, material, color, etc. of the ground paving, which has become a prominent factor affecting the overall aesthetics. In view of this, we propose an adaptive gravity-balanced hidden gutter cover. Utility Model Content

[0004] The main purpose of the utility model is to provide an adaptive gravity-balanced hidden drainage ditch cover, which can solve the problems raised in the above-mentioned background technology.

[0005] In order to achieve the above-mentioned purpose, the utility model proposes an adaptive gravity-balanced hidden drainage ditch cover plate, comprising a drainage ditch, to which a cover plate and a drainage filter assembly are detachably connected, and the drainage filter assembly comprises:

[0006] A drainage ditch cover plate outer frame, wherein a rotating sleeve is fixedly connected to the lower side of the drainage ditch cover plate outer frame;

[0007] A rotating sheet, wherein the rotating sheet is fixedly connected to the outer wall of the rotating sleeve, and the rotating sleeve is penetrated by the fixed shaft and is rotatably connected to the fixed shaft;

[0008] and a filter screen, wherein the filter screen is fixedly connected to the inner wall of the outer frame of the drainage ditch cover.

[0009] Preferably, the center lines of the rotating sleeve and the rotating sheet are not in the same vertical plane.

[0010] Preferably, the end of the rotating piece close to the rotating sleeve is heavier than the end of the rotating piece far from the rotating sleeve. When the drainage filter assembly is not working, the rotating piece is in a horizontal state. When the drainage filter assembly is working, due to the inconsistent weight of rainwater on the rotating piece, the weight of the rainwater causes one side of the cover plate to sink under the action of the gravity difference, resulting in further shifting of the center of gravity, and the cover plate begins to tilt, thereby achieving drainage.

[0011] Preferably, the rotating plates are provided in a plurality of groups, and the plurality of groups of rotating plates are arranged in an equidistant array on the outer frame of the drainage ditch cover.

[0012] Preferably, the outer frame of the gutter cover is hollow. Through the hollow-shaped gutter cover, the filter net blocks fallen leaves, garbage and other debris from entering the gutter, ensuring smooth drainage, so that some impurities in the drainage process can be filtered by the filter net. The impurities are gathered on the filter net, making it convenient for subsequent staff to take out the outer frame of the gutter cover for centralized treatment of the impurities.

[0013] Preferably, a positioning groove is provided on the inner surface of the drainage ditch, and the positioning groove is used to support the placement of the cover plate and the drainage filter assembly.

[0014] The utility model provides an adaptive gravity-balanced hidden drainage ditch cover, which has the following beneficial effects:

[0015] (1) The adaptive gravity-balanced hidden gutter cover uses a drainage filter assembly. When the device is not draining water, it is the same as the ground and the drainage outlet is not visible. The drainage outlet will only appear when it rains or when draining water. After the water is drained, it will return to its original state, achieving a concealed effect and improving the overall aesthetics.

[0016] (2) The adaptive gravity-balanced hidden gutter cover utilizes gravity to automatically tilt and open the rotating piece, using natural gravity as the driving force. It does not require external energy supply, reduces energy consumption and carbon emissions, is not dependent on external energy, does not generate noise, and requires relatively little maintenance and repair work, thereby achieving environmental protection and energy saving.

[0017] (3) After the rainwater is drained away, the adaptive gravity-balanced hidden gutter cover automatically returns to a balanced closed state with the help of gravity.

[0018] (4) The adaptive gravity-balanced hidden gutter cover uses a drainage filter assembly so that after the rotating plate is opened, the fallen leaves and other garbage on the rotating plate can be lifted up without affecting drainage. The filter net can also prevent debris from clogging the gutter. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] See also Figure 1-Figure 3 The utility model proposes an adaptive gravity-balanced hidden gutter cover, comprising a gutter 1. A positioning groove 101 is provided on the inner surface of the gutter 1. By using the gutter 1, a cover 2 and a drainage filter assembly 3 can be aligned. The gutter 1 is detachably connected with the cover 2 and the drainage filter assembly 3. By using the drainage filter assembly 3, the device is in the same form as the ground when not draining water, and no drainage outlet can be seen. The drainage outlet will only appear when it rains or when draining water. The drainage outlet will return to its original state after the water is drained, thereby achieving a concealed effect and improving the overall aesthetics.

[0028] In the embodiment of the utility model, in order to be able to perform normal drainage work, specifically, the drainage filter assembly 3 includes a drainage ditch cover outer frame 5, a rotating piece 6 and a filter screen 9. The lower side of the drainage ditch cover outer frame 5 is fixedly connected with a rotating sleeve 8, the rotating piece 6 is fixedly connected to the outer wall of the rotating sleeve 8, the rotating sleeve 8 is penetrated by the fixed shaft 7 and is rotatably connected to the fixed shaft 7, and the filter screen 9 is fixedly connected to the inner wall of the drainage ditch cover outer frame 5. Through the action of the filter screen 9, debris is prevented from clogging the drainage ditch. The center lines of the rotating sleeve 8 and the rotating piece 6 are not in the same vertical plane. The end of the rotating piece 6 close to the rotating sleeve 8 is heavier than the end of the rotating piece 6 away from the rotating sleeve 8. There are multiple groups of rotating pieces 6, and the multiple groups of rotating pieces 6 are equidistantly arranged in an array on the drainage ditch cover outer frame 5. 5 is hollow. When it starts to rain, rainwater gradually accumulates on the surface of the rotating piece 6. Due to the offset design of the center of gravity of the rotating piece 6, when the accumulated water reaches a certain amount, the weight of the rainwater causes one side of the rotating piece 6 to sink, resulting in a further offset of the center of gravity, and the rotating piece 6 begins to tilt. After the rotating piece 6 is opened, the fallen leaves and other garbage on the rotating piece 6 can be lifted without affecting the drainage, thereby achieving drainage work. After the rainwater is drained, the rotating piece 6 rotates and resets, so that the rotating piece 6 blocks the gap and is on the same horizontal plane as the gutter cover outer frame 5, thereby improving the overall aesthetics. In addition, the rotating piece 6 is opened by gravity as a driving force, without the need for external energy supply, thereby reducing energy consumption and carbon emissions, not relying on external energy, and generating no noise. The maintenance and repair work is relatively less, thereby achieving environmental protection and energy saving.

[0029] Furthermore, by determining the size and weight of the cover: determine the length and width of the rotating piece 6 according to the size of the drainage ditch 1 designed on the site, calculate its total weight according to the material and volume of the rotating piece 6, then calculate the center of mass position of the rotating piece 6, and then calculate the center of gravity offset distance, where the center of gravity offset distance is equal to the length of the cover * sin (tilt angle) / 2. Finally, by calculating the site catchment area, local annual rainfall, site paving material, etc., this special drainage ditch cover system is uniformly calculated and formulated.

[0030] During use, when it starts to rain, rainwater gradually accumulates on the surface of the rotating piece 6. Due to the offset design of the center of gravity of the rotating piece 6, when the accumulated water reaches a certain amount, the weight of the rainwater causes one side of the rotating piece 6 to sink, causing the center of gravity to further shift, and the rotating piece 6 begins to tilt. The fallen leaves and other garbage on the rotating piece 6 are lifted up to achieve drainage. After the rainwater is drained, the rotating piece 6 rotates and resets, so that the rotating piece 6 blocks the gap and is on the same horizontal plane as the outer frame 5 of the gutter cover.

[0031] The above description is only a preferred embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the inventive concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
