Further, as shown in fig. 2 and 6, in the embodiment of the present invention, a transverse guide rail 207 is further provided on the brake body 200, a transverse sliding block 2041 matched with the transverse guide rail 207 is fixedly installed at an end of the push-pull frame 204, and the transverse sliding block 2041 is slidably supported in the transverse guide rail 207, so that a transverse moving path is maintained when the support baffle 205 moves.
With continued reference to fig. 1, 2 and 6, in the embodiment of the present invention, the floating block mechanism further includes a second floating block 202, the second floating block 202 is supported and fixedly installed on a second lifting gear 2021, the gate body 200 is further provided with a first vertical guide rail 206, the second lifting gear 2021 is supported and slidingly disposed in the first vertical guide rail 206, the second lifting gear 2021 has a rack that can be meshed with the rotating gear 203, so that when the water level on the water facing side of the filtering portion 300 rises to submerge the second floating block 202, the second floating block 202 floats, and pushes the second lifting gear 2021 to move upwards, when the second lifting gear 2021 that moves upwards is meshed with the rotating gear 203, the rotating gear 203 drives the rotating gear 203 to rotate, and the rotating gear 203 makes the guide pillar 2031 perform a circular motion, so as to push the supporting baffle 205 to displace, so that the supporting baffle 205 moves away from above the first lifting gear 2011.
As a preferred embodiment of the present invention, the second floating block 202 is located at a higher level than the first floating block 201, and it is understood that when the filtering portion 300 is blocked, the water level on the water facing side of the filtering portion 300 will continuously rise, and the supporting baffle 205 is initially located at the top end of the first lifting rack 2011 due to the fact that the height of the first floating block 201 is lower than the height of the second floating block 202, so that the first floating block 201 will not move upwards after being submerged by the water level; as the water level rises, after the water level submerges the second floating block 202, the second floating block 202 moves upwards, so that the rotating gear 203 rotates to move the supporting baffle 205 away from the upper side of the first lifting gear rod 2011, at this time, because the first floating block 201 is already located at a deeper position in the water body, the buoyancy of the first floating block 201 is relatively large, when the supporting baffle 205 releases the first lifting gear rod 2011, the first floating block 201 moves upwards, so that after the first lifting gear rod 2011 is meshed with the driving bevel gear 701, the driving bevel gear 701 is driven to rotate by the first floating block 201 which moves upwards, and the cleaning rod 705 is further driven to rotate, so that the cleaning brush 7051 on the cleaning rod 705 is utilized to clean the blocked second filtering hole 3021.
Further, referring to fig. 1, in the embodiment of the present invention, a liquid level sensor 602 and a controller 603 are further disposed on the top of the gate body 200, a control signal input end of the controller 603 is connected to the liquid level sensor 602, and a control signal output end of the controller 603 is connected to the lifting motor 601; when the effect of cleaning the blocked second filter hole 3021 by the cleaning assembly is insufficient, the water level that continuously rises will reach the liquid level sensor 602, the liquid level sensor 602 sends a signal to the controller 603, the controller 603 controls the lifting motor 601 to act, and the lifting motor 601 drives the lifting assembly 600 to act, so that on one hand, the impurity garbage in the lifting cavity 304 is lifted and discharged, and on the other hand, the blocked first filter through hole 3011 is cleaned, so that the water flow can smoothly pass through the filter part 300.
It can be appreciated that when the water level drops, the first floating block 201 will be reset to the position just above the first lifting rack 2011 after the first lifting rack 2011 blocks the supporting baffle 205. Although embodiments of the invention have been disclosed above, they are not limited to the use listed in the specification and embodiments. It can be applied to various fields suitable for the present invention. Additional modifications will readily occur to those skilled in the art. Therefore, the invention is not to be limited to the specific details and illustrations shown and described herein, without departing from the general concepts defined in the claims and their equivalents.
