Detailed Description
As shown in fig. 1 and 2, this embodiment discloses a pit drainage alarm device for installing a lifting motor for a heating furnace outlet, which comprises a shell 1, a micro switch 2, an on-off control mechanism 3 and a floating ball 4.
The shell 1 is of a cavity structure, the shell 1 is composed of a top cover 101 and a shell 102, the top cover 101 is fixed on the shell 102 through a bolt assembly, an outgoing line pipe 103 is welded on the top cover 101, the micro switch 2 is arranged in the shell 102, terminals on the micro switch 2 are electrically connected with a controller through wires, and connecting wires penetrate through the outgoing line pipe 103.
The on-off control mechanism 3 is arranged in the shell 102, the on-off control mechanism 3 comprises a top pressing plate 301, the top surface of the top pressing plate 301 corresponds to the contact of the micro switch 2, guide slide bars 302 are arranged on two sides of the top pressing plate 301, the top pressing plate 301 is in sliding connection with the guide slide bars 302, nuts 303 are arranged at the upper ends of the guide slide bars 302, the lower ends of the guide slide bars are fixed with the bottom of the shell 102, springs 304 are sleeved on the guide slide bars 302, the upper ends of the springs 304 are propped against the top pressing plate 301, and the lower ends of the springs 304 are propped against the bottom of the shell 102.
As shown in fig. 3, the floating ball 4 is of a hollow structure, which is made of stainless steel, the top surface of the floating ball 4 is connected with a flexible rope 5, and the upper end of the flexible rope 5 penetrates through a first reserved wire passing hole 6 at the bottom of the shell 102 and then is connected with the top pressing plate 301.
The working principle of the utility model is as follows: the floating ball 4 is a pulling force driving source of the flexible rope 5, when water is not in the pit 10, the floating ball 4 pulls the top pressing plate 301 to slide down along the guide slide rod 302 through the flexible rope 5, so that the top pressing plate 301 is separated from a contact of the micro switch 2, and at the moment, the drainage pump stops working. When water exists in the pit 10, the floating ball 4 rises under the action of water buoyancy, the flexible rope 5 is positioned on the loosening turntable, the pressing plate 301 rises under the action of the spring 304 and presses the contact of the micro switch 2, and at the moment, the drainage pump works to drain accumulated water in the pit 10.
