Description

Technical Field

[0001] The utility model relates to the technical field of elevator pit water level detection, in particular to an elevator pit water level detection device. Background Art

[0002] The part of the shaft below the lowest floor station served by the car is called the pit, which is equipped with a buffer, elevator stop switch, shaft light switch, power socket and lighting. A pit door can be installed as needed. The pit should have enough space and its bottom should be smooth and flat without water accumulation. Its structure should be able to withstand the compressive strength of the reaction force when the car or counterweight collides with the buffer. When the elevator is flooded, first turn off the main power supply to prevent electrical short circuit and equipment damage. At the same time, use the sliding method to stop the elevator at the highest floor to prevent water from soaking the elevator car and its electrical equipment.

[0003] However, it still has some shortcomings. For example, after heavy rain, the components in the elevator pit may be submerged by water due to untimely drainage. When there is water in the elevator pit, it is difficult for staff to arrive at the scene in time to deal with the water, which reduces the efficiency of water treatment. Moreover, when the water in the elevator pit reaches a certain depth, it is impossible to give a warning in time, resulting in risks during the operation of the elevator.

[0004] In order to solve the above problems, this application proposes an elevator pit water level detection device. Utility Model Content

[0010] Preferably, the upper outer surface of the detection box is fixedly connected to a supporting round rod, the outer wall of the supporting round rod is slidably connected to a floating ball, and the upper outer surface of the detection box is fixedly connected to a fixed baffle.

[0011] Preferably, one side outer surface of the fixed baffle is fixedly connected to a limit baffle, one side inner surface of the limit baffle is slidably connected to a sliding block, and one side outer surface of the sliding block is movably connected to a switch button.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] The utility model has the ability to float on the water surface after gas is injected into the floating base. After the water level rises, the lifting plate rises under the action of the floating base, and the depth of the water level is determined by the scale on the outer wall of the supporting column. At the same time, the fixed round rod rises with the lifting plate. When the top of the fixed round rod touches the top of the early warning body, the power in the distribution box is started to make the water pump in the water tank work, and the water in the elevator pit is absorbed into the water tank under the action of the water inlet pipe, so as to avoid too much water accumulation in the elevator pit affecting the movement of the staff.

By injecting gas into the floating base 14, the floating base 14 can be made to float on the water surface. After the water level rises, the lifting plate 13 rises under the action of the floating base 14, and the depth of the water level is determined by the scale 11 on the outer wall of the supporting column 10.

[0023] In this embodiment, Figure 4As shown, the outer surface of the upper end of the detection box 3 is fixedly connected with a supporting round rod 21, and the outer wall of the supporting round rod 21 is slidably connected with a floating ball 22.
