Detailed Description
The following examples are for illustrative purposes only and are not intended to limit the scope of the present invention.
Examples
Referring to fig. 1-3, a water level monitoring and alarming device for a sewage treatment tank comprises an installation block 1, a connecting pipe 2 is fixedly connected to the side wall of the installation block 1 in a sealing manner, a first chute 3 is arranged on the side wall of the installation block 1 positioned in the connecting pipe 2, a first magnetic slider 4 is connected in the first chute 3 in a sliding manner, a first spring 5 is fixedly connected between one end of the first magnetic slider 4 far away from the connecting pipe 2 and the inner wall of the first chute 3, a first pull rope 6 is horizontally and fixedly connected to one end of the first magnetic slider 4 far away from the first spring 5, a movable pulley 7 is connected on the inner wall of the connecting pipe 2 in a transverse sliding manner, hooks are arranged at the left end and the right end of the movable pulley 7, one end of the first pull rope 6 far away from the first magnetic slider 4 is fixedly connected with the hook at the right end of the movable pulley 7, a second pull rope 8 is, an installation frame 9 is further fixedly connected to the inner wall of the connecting pipe 2, a first fixed pulley 10 and a second fixed pulley 11 which are matched with the second pull rope 8 are rotatably arranged on the installation frame 9, one end, far away from the hook body at the left end of the movable pulley 7, of the second pull rope 8 sequentially winds the first fixed pulley 10, the movable pulley 7 and the second fixed pulley 11, then vertically extends downwards and is fixedly connected with a floating block 12, and the floating block 12 is also positioned inside the connecting pipe 2; the diameter of the second fixed pulley 11 is larger than that of the first fixed pulley 10, so that the second pull rope 8 is prevented from contacting when being wound between the first fixed pulley 10 and the second fixed pulley 11, friction resistance is generated in the transmission process, and the transmission effect is prevented from being influenced;
the installation block 1 is also internally provided with a position indicating alarm mechanism matched with the floating block 12 for use, the position indicating alarm mechanism comprises an installation cavity arranged in the installation block 1, the bottom in the installation cavity is provided with a second sliding chute 13, the second sliding chute 13 is internally connected with a second magnetic slider 14 in a sliding manner, the second magnetic slider 14 corresponds to the first magnetic slider 4 in position and attracts each other, the upper end of the second magnetic slider 14 is horizontally welded with a rack 15, the installation cavity is also internally and rotatably connected with a rotating shaft 16 in a penetrating manner, one end of the rotating shaft 16, which is positioned in the installation cavity, is fixedly sleeved with a gear 17, the gear 17 is meshed with the rack 15, the surface of the installation block 1 is also embedded with a dial 18, one end of the rotating shaft 16, which is far away from the gear 17, penetrates into the interior of the dial 18 and is positioned in the center of the dial 18, and, still fixed mounting has an alarm 20 in the 1 upper end of installation piece, and a mounting groove 21 has still been seted up to the left side of second spout 13, and mounting groove 21 internally mounted have with alarm 20 electric connection touch switch 22 and a plurality of second spring 23, the common fixedly connected with wedge block 24 in second spring 23 upper end, wherein the bottom surface of wedge block 24 does not just touch switch 22 with touching, and the inclined plane end of wedge block 24 stretches out mounting groove 21 and towards rack 15 completely just.
When the device is used, the connecting pipe 2 of the device is partially inserted into sewage in a sewage treatment tank, when the water level is normal, the floating block 12 in the connecting pipe 2 is in a free floating state, the second pull rope 8 and the first pull rope 6 are also in a loose state, the first magnetic slide block 4 is always positioned at the position close to the right end of the first sliding groove 3 under the limiting action of the first spring 5, when the water level in the sewage treatment tank descends, the floating height of the floating block 12 is also reduced along with the water level, and the first pull rope 6 and the second pull rope 8 are also tensioned; when the water level in the sewage treatment tank continuously descends, as the volume of sewage drained by the floating block 12 is smaller and smaller, the buoyancy borne by the floating block 12 is smaller and smaller, the self gravity of the floating block 12 can pull the second pull rope 8 and the first pull rope 6 to enable the movable pulley 7 and the first magnetic slider 4 to slide leftwards, as the second magnetic slider 14 corresponds to the first magnetic slider 4 in position and attracts each other, the second magnetic slider 14 also slides leftwards along the second sliding groove 13 when the first magnetic slider 4 slides leftwards, so that the rack 15 is driven to move leftwards, the rack 15 moves leftwards can drive the gear 17 to rotate clockwise, so that the pointer 19 in the dial 18 is driven to rotate clockwise, and the larger the clockwise rotation angle of the pointer 19 is, the lower the water level is indicated, so that a worker can detect the water level in the sewage treatment tank by observing the dial 18 and the pointer 19;
when the pointer 19 rotates to a position outside the scale value on the dial 18, the water level in the sewage treatment tank is close to the lower limit water level at the moment, the left end of the rack 15 is just abutted to the inclined surface end of the wedge block 24, the wedge block 24 is slightly abutted to the mounting groove 21, and therefore the tact switch 22 is pressed down to electrify the alarm 20 to send an alarm to remind a worker to take emergency measures; after the water level in the sewage treatment tank is recovered to be normal, the floating height of the floating block 12 is increased again, the size of the borne buoyancy is increased again, and the device can be completely recovered to the initial state to continuously monitor the water level under the action of the restoring force of the first spring 5 and the second spring 23; it is worth to be noted that under the action of the pulley block formed by the first fixed pulley 10, the second fixed pulley 11 and the movable pulley 7, the pulling force of the first pull rope 6 on the first magnetic slide block 4 is about three times of the pulling force of the floating block 12 on the second pull rope 8, so that the pointer 19 has higher sensitivity to water level changes, and the monitoring effect is more accurate.
The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the invention, and any modifications, equivalents, improvements and the like that fall within the spirit and principle of the present invention are intended to be included therein.
