Description
Technical Field
[0001] The utility model relates to the technical field of municipal drainage equipment, in particular to an adjustable overflow device and an overflow rainwater outlet. Background Art
[0002] Sponge city is a new generation of urban stormwater management concept, which means that the city can adapt to environmental changes and deal with natural disasters caused by rainwater like a sponge, and has good flexibility. It can also be called a "water-elastic city". Currently, the ecological construction of sponge cities is being fully implemented in my country.
[0003] A sponge city is a city that sets up a large amount of green space, and uses the seepage effect of the soil to quickly infiltrate rainwater into the ground. In the city, through the reasonable planning of slope and terrain, green space is built in the lower terrain area, and the drainage system is used to divert rainwater to the infiltration ground in the green space. This can not only alleviate the problem of urban waterlogging caused by a large amount of rainwater, but also optimize the urban environment, and assist the planning and development of the city through ecological construction.
[0004] Green spaces used for infiltration of excess rainwater cannot meet the requirements of rainwater infiltration by simply reclaiming land and planting flowers and plants. Green spaces need to be built in accordance with standards, and when the rainfall exceeds the designed water level of the green space, the rainwater gathered in the green space will accumulate to form stagnant water. If the stagnant water in the green space cannot be drained for a long time, it may breed bacteria or pests and diseases, and eventually lead to water pollution. For this reason, it is necessary to consider setting up overflow outlets that can continue to drain the stagnant water after the green space is saturated with infiltration when building a sponge city system.
[0005] However, the setting of the overflow outlet needs to be designed according to the actual carrying capacity of each green space. The existing overflow outlet lacks adjustment flexibility, and when the rainfall changes, the overflow height cannot be adjusted in time to meet different rainfall requirements. Utility Model Content
[0006] Therefore, in order to solve the above problems, the utility model provides an adjustable overflow device and an overflow rainwater outlet.

[0012] In a possible implementation, when the water baffle moves, its bottom end does not exceed the bottom end of the opening of the overflow hole, and the top end of the water baffle does not exceed the top end of the opening of the overflow hole.

[0050] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.
[0051] Example 1
[0052] Please refer to Figure 1-Figure 7 , is an adjustable overflow device disclosed in this embodiment, which includes a base 1, a shell 2, a water baffle 3 and a top cover 4. The shell 2 is arranged on the base 1, and has an overflow cavity 21 therein, and has at least one overflow side wall 22, and the overflow side wall 22 is provided with a plurality of overflow holes 221 connected to the overflow cavity 21, and the base 1 is provided with a drain port 11, which is connected to the overflow cavity 21, and rainwater enters the overflow cavity 21 through the overflow hole 221 and is discharged through the drain port 11.
[0053] The shape of the housing 2 can be specifically set according to the required shape in the actual application scenario. Figure 1-Figure 4 As shown, in a specific implementation, it can be formed by four side panels, thereby forming a shell 2 with four side walls; in another specific implementation, the shell 2 can be integrally formed. The overflow side wall 22 of the shell 2 can be one to four. Figure 1-Figure 4 The overflow side walls 22 are shown as four in the figure. The size, shape and number of the overflow holes 221 on the overflow side walls 22 can also be set according to the water flow requirements in the actual application scenario. Figure 5As shown, in a specific implementation, a snap-in groove 224 is provided at one end of the overflow side wall 22, and a snap-in piece 225 is provided at the other end, and two adjacent overflow side walls 22 are snap-connected through the snap-in groove 224 and the snap-in piece 225, that is, the snap-in piece 225 of one overflow side wall 22 is snap-connected to the snap-in groove 224 of another adjacent overflow side wall 22. Figure 1 and Figure 3 As shown, in a specific implementation, the overflow hole 221 is arranged at the upper half of the overflow side wall 22. The overflow device provided in this embodiment is arranged in the green space. When the rainfall exceeds the design water level of the green space, the rainwater can be discharged into the river or the municipal pipeline through the overflow hole 221 to avoid water accumulation in the green space. If the accumulated water cannot be emptied for a long time, bacteria or pests will breed and cause water pollution.
[0054] like Figure 1-Figure 4 As shown, the size of the overflow hole 221 is adjustable, so that the device is suitable for the load design of different green spaces for the amount of rainwater. A water retaining plate 3 is provided on the overflow side wall 22. Figure 1-4 As shown, the water baffle plate 3 can be arranged inside the shell 2. Of course, the water baffle plate 3 can also be arranged outside the shell 2, and can be arranged according to actual needs. The water baffle plate 3 can move up and down along the overflow side wall 22, so as to change the size of the overflow hole 221. When the water baffle plate 3 is not opened, it is located in the lower half of the overflow side wall 22, and it will not completely block the overflow hole 221; when the water baffle plate 3 is in the open state, it rises along the overflow side wall 22, partially blocking the overflow hole 3, and the bottom end of the water baffle plate 3 never exceeds the bottom end of the overflow hole 221, that is, it keeps blocking the lower half of the overflow hole 221, and the top end of the water baffle plate 3 never exceeds the top end of the overflow hole 221, that is, the water baffle plate 3 will not safely block the overflow hole 221. In a specific implementation of the present embodiment, Figure 6 As shown, a limit block 31 is provided on the water retaining plate 3, and a limit hole 226 is correspondingly provided on the overflow side wall 22. The limit block 31 is clamped in the limit hole 226 so that the water retaining plate 3 can move up and down relative to the overflow side wall 2. The adjustable overflow device provided by the utility model can adjust the size of the overflow hole 221 and flexibly adjust the overflow height to meet the requirements of different green space design water levels by providing a water retaining plate 3 that can move up and down along the overflow side wall 22 on the overflow side wall 22. In a specific implementation, Figure 1-Figure 4 As shown, the water baffle plate 3 is a single plate respectively arranged on the four overflow side walls 22 ; in another specific implementation, the water baffle plate 3 may be integrally formed and arranged on the shell 2 .
[0055] like Figure 3-Figure 4As shown, a telescopic device 223 is provided in the spacing column 222 formed between two adjacent overflow holes 221 on the overflow side wall 22. When the telescopic device 223 is unfolded, the overflow side wall 22 is driven to unfold, and the overflow hole 221 is enlarged. In a specific implementation of the present embodiment, the telescopic device 223 includes an inner column 2231 and an outer column 2231 sleeved on the inner column 2231. The inner column 2231 is provided with a plurality of first through holes 2231a, and the outer column 2232 is correspondingly provided with a plurality of second through holes 2232a. When the telescopic device 223 is unfolded, the overflow side wall 22 can be unfolded into two parts, the upper and lower parts, and the outer column 2232 moves upward relative to the inner column 2231. As the overflow side wall 22 is unfolded, the overflow hole 221 is correspondingly enlarged. As shown in FIG. Figure 7 As shown, in this embodiment, the relative positions of the inner column 2231 and the outer column 2232 are fixed by simultaneously passing the limit screw 2233 through the first through hole 2231a and the second through hole 2232a, thereby adjusting the expansion or retraction of the telescopic device 223. When the rainfall suddenly increases, enlarging the overflow hole 221 can effectively improve the drainage efficiency, timely discharge the green space water, avoid waterlogging, and improve the practicality of the device.
[0056] like Figure 1 and Figure 4 As shown, the top cover 4 is buckled on the top of the shell 2, and a hanging step 23 is provided at the opening of the shell 2. The top cover 1 is detachably connected to the top of the shell 2 through the hanging step 23, which is convenient for disassembly to maintain the inside of the device. In a specific implementation, a plurality of evenly arranged water holes 41 are provided on the top cover 4. When the rainfall exceeds the designed water level of the green space, the rainwater can be discharged into the river or municipal pipeline through the water holes 41 to avoid water accumulation in the green space. If the accumulated water cannot be emptied for a long time, bacteria or pests will breed and cause water pollution. Here, the size, shape and number of the water holes 41 can also be set according to the water flow requirements in the actual application scenario. In another specific implementation, no water holes are provided on the top cover 4, which is suitable for road paving.
[0057] In a specific implementation, Figure 2 As shown, a drain port 11 is provided on the base 1, and the size and shape of the drain port 11 can be set according to the drainage requirements in the actual application scenario, for example Figure 2 In the figure, a square hole is shown, but in actual setting, a circular hole may also be used; in another specific implementation, as shown in FIG. Figure 8 As shown, a drain port 11 is provided on the base 1, and extends outwardly in a direction away from the housing 2 to form a pipe port 12. The size and shape of the pipe port 12 correspond to the size and shape of the drain port 11. For example, Figure 8 In the figure, a square opening is shown. In actual setting, if the drain outlet 11 is set as a circular hole, the pipe outlet 12 is correspondingly set as a circular opening.
[0058] In summary, the adjustable overflow device provided in the embodiment of the utility model can adjust the size of the overflow hole 221 and flexibly adjust the overflow height to meet the requirements of different green space design water levels by setting a water baffle 3 that can move up and down along the overflow side wall 22. At the same time, this embodiment is provided with a plurality of overflow holes 221 connected to the overflow cavity 21 on the overflow side wall 22, and a plurality of water through holes 41 can be provided on the top cover 4. When the rainfall exceeds the design water level of the green space, the rainwater can be discharged into the river or municipal pipeline through the overflow hole 221 and the water through hole 41 of the overflow device, so as to avoid water accumulation in the green space, and the water pollution caused by the breeding of bacteria or pests due to the inability to drain the accumulated water for a long time.
[0059] In a specific application of this embodiment, Fig. 9 As shown, the adjustable overflow device provided in this embodiment can be applied to green space; in another specific application of this embodiment, as Fig.10 As shown, the adjustable overflow device provided in this embodiment can be applied to road paving.
