Detailed Description
The invention is further described below with reference to the following examples and figures:
example one
The whole device of this embodiment is all placed in water or other liquid, and floater 1 receives the effect of buoyancy in liquid, can go up and down along with the fluctuation of liquid level. Be provided with two waterproof switch control box 5 in this embodiment, be provided with waterproof control switch 51 on the switch control box 5, control switch 51 is button control switch 51, and two control switch 51 all are connected with the water pump through the wire. The upper end button is pressed at a high liquid level, the water pump is started to pump water or liquid to the outside, and the liquid level is lowered. When the liquid level drops to a certain height, the button at the lower end needs to be pressed to turn off the water pump. The two control switches 51 control the water pump in a manner similar to a double control switch of a household electric lamp, and any one control switch 51 can independently control the water pump.
Based on the above working conditions, the specific structure of this embodiment is as shown in fig. 1, fig. 2 and fig. 3, the passive double-stop displacement device includes a floating ball 1, a floating rod 2 and a stop 3, a through sliding hole 14 is formed in the floating ball 1, the floating rod 2 penetrates through the sliding hole 14, so that the floating ball 1 is sleeved on the floating rod 2, and the floating rod 2 is a polished rod, so that the floating ball 1 can move along the floating rod 2 without hindrance. Two ends of the floating rod 2 are respectively provided with a backstop 3, and the floating ball 1 is positioned between the two backstops 3. The passive double-gear moving device is placed in the guide cylinder 4, button type control switches 51 are arranged above and below the passive double-gear moving device, and the control switches 51 are arranged on the switch control box 5.
The floating ball 1 comprises an outer side wall 11 and an inner side wall 12, the inner side wall 12 is enclosed into a hollow tubular shape, and the hollow part is a sliding hole 14. The outer side wall 11 is arranged outside the inner side wall 12, the outer side wall 11 is connected with the inner side wall 12 in a seamless mode, and the outer side wall 11 and the inner side wall 12 enclose a closed annular cavity 13. Because the floating ball 1 is in a capsule shape, and the guide cylinder 4 is in a tubular shape, (only the guide cylinder is in a sectional structure in fig. 1), the inner diameter of the guide cylinder 4 is only slightly larger than the size of the transverse section of the floating ball 1. Therefore, the floating ball 1 mainly moves up and down in the vertical direction, and the moving amount in the horizontal direction is small.
The two stoppers 3 on the floating rod 2 have the same structure and both comprise a main body 31 and a screw 33, a through mounting hole is formed in the main body 31, and the floating rod 2 passes through the mounting hole, so that the main body 31 is sleeved on the floating rod 2. The main body 31 is further provided with a threaded hole 32, the threaded hole 32 is communicated with the mounting hole, a screw 33 is installed in the threaded hole 32 through threaded fit, and the front end of the screw 33 is abutted against the floating rod 2. When the screw 33 is tightened, the stop 3 can be tightly connected to the float rod 2.
The specific principle of the embodiment is as follows: the passive double-gear control mechanism is placed in a pool or a vacuum well, and the guide cylinder 4 and the switch control box 5 are fixed on the inner wall of the pool or the vacuum well. When the water level rises, the floating ball 1 moves upwards along the floating rod 2 under the buoyancy action of the water. Along with the gradual rise of the water level, the floating ball 1 is propped against the backstop 3 at the upper end of the floating rod 2, and the floating ball 1 drives the floating rod 2 to move upwards. The floating rod 2 is abutted against the control switch 51 above the guide cylinder 4, and the continuous rising of the water level can immerse more parts of the floating ball 1 in the water, so that the buoyancy force applied to the floating ball 1 is increased, and the control switch 51 is pressed down. The control switch 51 can automatically start the water pump to drain after being pressed, so that the passive double-gear control mechanism can automatically drain when the water level rises to a certain height.
After the water pump starts to drain, the water level in the water tank or the vacuum well drops, and the upper end of the floating rod 2 is separated from the control switch 51 above the guide cylinder 4. However, at this time, the control switch 51 on the upper side is already pressed, and therefore the water pump does not stop discharging water. Along with the gradual decline of water level, floater 1 pushes up with backstop 3 of the lower extreme of float lever 2, and float ball 1 drives float lever 2 downstream. The floating rod 2 is abutted with the control switch 51 below the guide cylinder 4, the buoyancy of the water borne by the floating ball 1 is smaller and smaller along with the continuous descending of the water level, and the downward pressure of the floating rod 2 and the floating ball 1 on the control switch 51 is gradually increased. When the water level drops to a certain height, the floating rod 2 can press the control switch 51 below the guide cylinder 4, so that the water pump is turned off, and outward drainage is stopped.
Obviously, without departing from the principle of the present invention, several improvements or modifications should be considered as the protection scope of the present invention.
