DETAILED DESCRIPTION

[0024] 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.

[0025] like Figure 1 , 2 As shown, a rainwater collection and filtration device for water ecological restoration includes: an ecological filter tank 1, the bottom of which is paved with a gravel layer 11; a filter pool 2, the filter pool 2 is arranged below the ecological filter tank 1; a filter frame 3, the filter frame 3 is detachably connected to the filter pool 2; an alarm mechanism, the alarm mechanism includes an alarm and a float switch 4, and the float switch 4 is arranged on the inner wall of the filter frame 3; a water reservoir 5, the water reservoir 5 is connected to the bottom of the filter pool 2 through a connecting pipe 6; a water collection mechanism 7, the water collection mechanism 7 is arranged at the top of the filter pool 2, and the water collection mechanism 7 includes a water collector 71 and a water collection pipe 72; a water pump 8, the water pump 8 is connected to a water pumping pipe 81, and the water pumping pipe 81 is arranged at the bottom of the water reservoir 5.

[0026] The top of the filter pool 2 is in the same plane as the bottom of the ecological filter tank 1. Grooves 21 are provided on all four sides of the top of the filter pool 2. The grooves 21 are rectangular grooves. The side walls of the grooves 21 do not penetrate the side walls of the filter pool 2. A protrusion 31 is provided on the top of the filter frame 3. The position of the protrusion 31 corresponds to the position of the groove 21. The protrusion 31 can be embedded in the groove 21. The groove 21 supports the protrusion 31 so that the filter frame 3 is erected in the filter pool 2. A filter hole 32 is provided at the bottom of the filter frame 3. The bottom of the filter frame 3 is suspended in the middle of the filter pool 2 under the support of the groove 21. The filter frame 3 intercepts garbage impurities contained in the passing rainwater through the filter hole 32, and the rainwater flows to the bottom of the filter pool 2.

[0027] A lifting ring 33 is provided on the inner wall at the top of the filter frame 3. When the garbage in the filter pool 2 is fully collected, a lifting device such as a crane or a winch is used to hook the lifting ring 33, and the filter frame 3 is lifted upward to separate the filter pool 2. The filter frame 3 is then transferred to the outside for garbage cleaning. After cleaning, the protrusion 31 of the filter frame 3 is placed in the groove 21 again, and the cleaning work can be continued.

[0028] Since the filter pool 2 and the filter frame 3 are both built underground, it is impossible to observe the patency of the filter pool 2 in time, so an alarm mechanism is used to report the storage situation of the filter pool 2. When the water level in the filter pool 2 reaches the warning range of the alarm mechanism, the alarm mechanism issues an alarm to notify relevant personnel to handle it.

[0029] like Figure 3 As shown, the float switch 4 is used to measure the water level height. The float switch 4 includes a slide bar 41, a floating ball 42 and a trigger button 43. The slide bar 41 is vertically fixed to the upper part of the filter frame 3, and the floating ball 42 is slidably connected to the slide bar 41. When the filter hole 32 is blocked by garbage, the garbage fills the filter frame 3 or the reservoir 5 is full of water, the water or garbage will push the floating ball 42 to move upward along the slide bar 41. When the float reaches the warning water level line, the floating ball 42 triggers the trigger button 43 located at the top of the slide bar 41.

[0030] The alarm is placed in the office of the monitoring personnel. The alarm is connected to the trigger button 43 signal. When the trigger button 43 is pressed, the alarm sounds an alarm. At this time, the monitoring personnel can react and process the filter frame 3.

[0031] The rainwater passing through the filter frame 3 enters the water reservoir 5 through the connecting pipe 6. The water levels of the water reservoir 5 and the filter tank 2 are the same due to the connecting vessel principle. Therefore, the alarm will also sound after the water reservoir 5 is full of water. At this time, relevant personnel need to take other water storage measures in time.

[0032] The bottom of the water reservoir 5 is an inclined surface. The height of the bottom of the water reservoir 5 near the connecting pipe 6 is higher than the height of the bottom of the water reservoir 5 away from the connecting pipe 6. The high surface of the water reservoir 5 is flush with the bottom of the connecting pipe 6.

[0033] In order to prevent a large amount of garbage from entering the filter pool 2 and causing frequent clogging of the filter hole 32, the water collector 71 is arranged in the gravel layer 11. The gravel layer 11 can filter out most of the large pieces of garbage. The gravel layer 11 also has a hydrophobic function, which can allow water to flow into the water collector 71. The water collector 71 is arranged on the top cover of the filter pool 2. The side wall of the water collector 71 is provided with a plurality of first water inlet holes 711. The first water inlet holes 711 are arranged horizontally. The plurality of first water inlet holes 711 can collect water from different directions, and the water collection efficiency is high. The bottom of the water collector 71 is provided with a second water inlet hole 712. The second water inlet hole 712 vertically penetrates the middle part of the water collector 71. The second water inlet hole 712 is connected to the filter pool 2. One end of the first water inlet hole 711 is also connected to the second water inlet hole 712. The water in the first water inlet hole 711 and the second water inlet hole 712 finally enters the filter pool 2.

[0034] The outlet of the water collecting pipe 72 is connected to the top of the water collector 71. The top of the water collecting pipe 72 is arranged outside the ecological filter tank 1. The water collecting pipe 72 collects water outside the ecological filter tank 1 and shares part of the drainage pressure of the ecological filter tank 1. A filter net is provided on the top of the water collecting pipe 72 to pre-filter some garbage.

[0035] like Figure 4 As shown, when water is needed during the dry season, the rainwater in the water reservoir 5 is pumped out for use through the water pump 8 and the pumping pipe 81. A filter head 82 is provided at the bottom of the pumping pipe 81 to prevent garbage from entering the pumping pipe 81 and clogging the water pump 8. The filter head 82 is located at one end of the water reservoir 5 away from the connecting pipe 6. Since the bottom of the water reservoir 5 is inclined toward the filter head 82, when storing rainwater during the dry season, as much water as possible in the water reservoir 5 can be pumped out.

[0036] Green plants are planted on the gravel layer 11, which can absorb, filter and purify part of the rainwater, and are also beneficial to the development of green ecological construction.

[0037] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein with equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
