[0033] Combining the above:

[0034] In order to realize silting inside the water collection gallery, the water level over-limit alarm and automatic drainage device of the water collection gallery also includes a silting component 2 arranged inside the water collection gallery body 1;

[0035] The dredging assembly 2 includes a support frame 24 arranged inside the water collection gallery body 1, a first motor 25 is installed on the upper surface of the support frame 24, the output shaft of the first motor 25 is inserted inside the support frame 24, the output shaft of the first motor 25 is fixedly connected with a first gear 29, the surface of the first gear 29 is symmetrically meshed with two second gears 210, the second gear 210 is rotatably connected to the support frame 24, the bottom surfaces of the second gear 210 and the first gear 29 are fixedly connected with a rotating shaft 27, the rotating shaft 27 passes through the support frame 24, and the bottom end of each rotating shaft 27 is fixedly connected with a cleaning plate 28, and the cleaning plate 28 is composed of a plurality of cleaning brush balls.

[0036] In this embodiment: when the water collection gallery body 1 needs to store water, water will flow from the pump body through the water inlet pipe 11 into the interior of the water collection gallery body 1, and the water level alarm 12 will detect the water level entering the water collection gallery body 1. When the water level reaches a certain height and needs to be discharged, the first motor 25 is connected to the external power supply and then started, and the first gear 29 connected to the output shaft of the first motor 25 starts to rotate inside the support frame 24, and the two second gears 210 meshing with the support frame 24 will rotate inside the support frame 24, and the rotating shaft 27 fixedly connected to the bottom of the second gear 210 and the first gear 29 will rotate inside the water collection gallery body 1, and the cleaning plate 28 fixedly connected to the bottom of the rotating shaft 27 will rub the inside of the water collection gallery body 1 to break up the sand and gravel stuck to the bottom of the water collection gallery body 1, thereby preventing the sand and gravel from remaining inside the water collection gallery body 1.

[0037] Going further:

[0038] In an optional embodiment, a plurality of stirring plates 26 are fixedly connected to the surface of each rotating shaft 27 .

[0039] In this embodiment: the stirring plate 26 fixedly connected to the surface of each rotating shaft 27 will stir the water flow, so that the broken sand and gravel are mixed with the water flow, so that the sand and gravel can be taken away when the water flows away to prevent them from sinking to the bottom again.

[0040] Going further:

[0041] In an optional embodiment, two slide grooves 21 are symmetrically opened inside the water collection gallery body 1, and sliders 23 are fixedly connected to both sides of the support frame 24.

[0046] In this embodiment: the second motor 34 is connected to an external power source and then started, and the screw 33 connected to the output shaft of the second motor 34 will rotate inside the drain outlet 31. Since the screw hole 35 and the screw 33 are engaged with each other, the rotation of the screw 33 will move the water retaining plate 32 upward inside the drain outlet 31, so that the water flow can flow away and the water level will be lowered.

[0047] The working principle and use process of the utility model are as follows: when the water collection gallery body 1 needs to store water, the water will flow from the pump body through the water inlet pipe 11 into the interior of the water collection gallery body 1, and the water level alarm 12 will detect the water level entering the interior of the water collection gallery body 1. When the water level reaches a certain height and needs to be discharged, the first motor 25 is connected to the external power supply and then started, and the first gear 29 connected to the output shaft of the first motor 25 starts to rotate inside the support frame 24, and the two second gears 210 meshingly connected to the support frame 24 will rotate inside the support frame 24, and the rotating shaft 27 fixedly connected to the bottom of the second gear 210 and the first gear 29 will rotate inside the water collection gallery body 1, and the cleaning plate 28 fixedly connected to the bottom of the rotating shaft 27 will rub the interior of the water collection gallery body 1 to break up the sand and gravel stuck to the bottom of the water collection gallery body 1, so as to prevent the sand and gravel from accumulating. The stirring plate 26 that remains inside the water collection corridor body 1 and is fixedly connected to the surface of each rotating shaft 27 will stir the water flow, so that the broken sand and gravel are mixed with the water flow, so that the sand and gravel can be taken away together when the water flows away to prevent sinking to the bottom again. When the two second gears 210 rotate, because a part of the second gear 210 passes through the support frame 24 and is engaged with the tooth plate 22, when the second gear 210 rotates, it will carry the support frame 24 to slide inside the slide groove 21 with the slider 23 as the fulcrum, so that the cleaning area is increased, and at the same time, the second motor 34 is connected to the external power supply and then started. The screw 33 connected to the output shaft of the second motor 34 will rotate inside the drain port 31. Because the screw hole 35 and the screw 33 are engaged with each other, the rotation of the screw 33 will carry the water retaining plate 32 to move upward inside the drain port 31, so that the water flow can flow away and the water level is lowered.
