The small pump that the utility model provides is protected warning device with low water level, comes entire circuit is controlled by a ball float is set in water tank, has prevented that water pump from not having at water tank under the situation of water, starts and causes problem such as idle running, and is simple in structure, easy to use.
Description of drawings
The small pump that Fig. 1 provides for the utility model is protected the structural representation of warning device with low water level.
Embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As shown in Figure 1; a kind of small pump of the present utility model is protected warning device with low water level; comprise shell 12; the transmission shaft 3 that fixedly installs; be installed in suspension rod 2 and the ball float 1 that is installed in suspension rod 2 one ends on the transmission shaft 3; described suspension rod 2 the other ends are connected with a stock 4 by transmission shaft 3; be provided with a compression spring 11 in the described stock 4; described compression spring 11 front ends are connected with pulley 6; described shell 12 inboards be provided with can be respectively around the top board 13 and the press table 7 that freely rotate away from an end of pulley 6 separately; described top board 13 is provided with the 1st groove 14 near pulley 6 one ends; described press table 7 is provided with the 2nd groove 15 near pulley 6 one ends; described top board 13 and press table 7 are connected with respectively be used to the spring that sets back; be provided with riser 10 between described top board 13 and the press table 7; described riser 10 centers are provided with a running shaft that riser 10 is rotated; described pulley 6 can slide up and down at described riser 10 rear sides; described riser 10 lower ends are positioned at the 2nd groove 15; the upper end can pass in and out the 1st groove 14 along with the slip of pulley 6, and described riser 10 front ends are provided with upper contact switch 8 and lower contact switch 9.
Described shell 12 inside are provided with upper spring 5b and lower spring 5a, the end of described upper spring 5b is connected these shell 12 end faces, the other end is connected on described stock 4 upsides, the end of described lower spring 5a is connected described shell 12 bottom surfaces, the other end is connected on described stock 4 downsides, and described upper spring 5b and lower spring 5a are toward each other.
The position of the running shaft of described riser 10 is higher than the position of transmission shaft 3, described top board 13 apart from the distance of pulley 6 less than the distance of press table 7 apart from pulley 6.
