Description
Technical Field
The utility model relates to an alarm device, in particular to alarm device for water inflow of elevator pit.
Background
According to the national standard requirements, the bottom of a pit of an elevator shaft is smooth and flat, and the pit cannot be used as a water accumulation pit. After the guide rail, the buffer, the fence and the like are installed and finished, the bottom pit cannot leak or seep water. However, in the practical use process, the situation that the pit can be filled with water is avoided, even a lot of water is stored in the pit, and the elevator still runs. These situations are serious threats to the safety of the elevator. Accidents of the elevator service building (burst water pipes, heavy rain, etc.) can easily be appreciated by the service units or maintenance personnel. Particularly, for an elevator with a pit arranged below a horizontal plane and a sump arranged unconditionally, when a waterproof layer of the pit is damaged, water seepage or water accumulation can occur in the pit of the elevator. The problems can not be timely found by one routine maintenance for 15 days, which affects the normal use and the safe service life of each part in a pit and the safe operation of the elevator. For the possibility, it is necessary to install an alarm device for detecting water inflow in the well.
SUMMERY OF THE UTILITY MODEL
In order to solve the defects of the prior art, the utility model aims at providing a detect alarm device that the well was intake.
In order to achieve the purpose, the utility model provides a detect elevator pit inflow alarm device, including floating unit, switch linkage unit and switch, the floating unit with the switch linkage unit is connected, the floating unit is placed in the basin of depositing near the well wall in the elevator pit, when ponding appears in the basin of depositing, the floating unit receives the buoyancy of water and floats and rises, the switch linkage unit also rises along with the floating unit; the switch is fixedly installed on the wall of the hoistway and connected with the elevator control system, the switch connection unit triggers the switch after rising, the switch transmits a signal representing pit water inflow to the elevator control system and triggers an alarm to remind elevator maintenance personnel to shut down and maintain.
Preferably, the floating unit is a floating ball, and the switch connection unit is a switch link.
Preferably, the switch is a multi-stage switch, the multi-stage switch is provided with different switch levels, and different switch levels are triggered by different rising heights of the switch connecting rod.
Advantageously, a switch box cover plate is further included to protect the switch.
The utility model has the advantages of, area is little, and does not occupy well horizontal space, arranges the convenience. The material is light material with corrosion resistance and poor hydrophilicity, such as plastic, stainless steel and the like, the manufacturing cost is low, and the water buoyancy principle is utilized, so that the water buoyancy tank is stable and reliable.

Detailed Description
As shown in fig. 1 and 2, an alarm device for detecting water inflow of an elevator pit comprises a floating unit, a switch connecting unit and a switch 3, wherein the floating unit is connected with the switch connecting unit, the floating unit is placed in a water storage tank 6 in an elevator pit 7 close to a hoistway wall 5, for example, the water storage tank 6 with the size of about 200mm x 100mm is left in the pit close to the hoistway wall 5, when water accumulation occurs in the water storage tank 6, the floating unit floats and rises due to the buoyancy of water along with the rising of a water level line 8, and the switch connecting unit also rises along with the floating unit; switch 3 fixed mounting is on well wall 5, is connected with elevator control system, the switch linkage unit rises the back and triggers switch 3, the signal of bottom pit intaking is represented to elevator control system transmission to the switch to show on the switch board and represent the mistake code that the bottom pit intake, and trigger the alarm, remind elevator dimension guarantor personnel to shut down the maintenance. The floating unit is a floating ball 1 or other objects capable of floating on the water surface, such as foam plastics, the switch connecting unit is a switch connecting rod 2, and can be made of stainless steel materials or aluminum and other light materials; switch 3 is multi-stage switch, multi-stage switch is provided with different switch grades, and different switch grades correspond different switch contacts, the height difference that switch connecting rod 2 rises, the switch contact that different switch grades of switch connecting rod 2's contact trigger correspond to demonstrate ponding water yield information on the panel, the maintenance personnel of being convenient for know the condition in advance. The switch box cover plate 4 is further included and used for protecting the switch from being interfered by falling objects, dust and other factors.
The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and changes will readily occur to those skilled in the art based upon the teachings of the present invention. Therefore, the technical solutions that can be obtained by logic analysis, reasoning or limited experiments based on the prior art according to the design concept of the present invention should be within the scope of the present invention and/or the protection scope defined by the claims.
