The to-be-solved technical problem of the utility model is: how to effectively detect the water level of an elevator shaft pit.
In order to solve the technical problem, the utility model provides a can detect buffer of elevator well pit water level, including the buffer body, one side of buffer body is fixed with the switch support, a serial communication port, the switch support on be fixed with water level detection device assembly.
Preferably, the water level detection device assembly comprises a buoy and a potentiometer, and the potentiometer is connected with the buoy and the alarm device.
Preferably, the switch bracket is of an integrated structure; and the switch bracket is provided with an arc-shaped groove which is matched and connected with the outer wall of the buffer body.
Preferably, the switch bracket comprises a first plate and a second plate connected with the first plate, the first plate and the second plate are provided with bending angles, the first plate is provided with a first hole, and the second plate is provided with a second hole and a third hole for installing the water level detection device assembly.
Preferably, the circular arc-shaped groove is formed in the first plate and the upper portion of the second plate.
The utility model discloses a water level detection device assembly of installation at buffer switch support makes water level detection device assembly and buffer become an organic whole to save the space of elevator well.
Through the utility model discloses a buffer can effectually detect the water level of elevator well bottom, when the position of harm electrical component and mechanical part is reachd to the water level, gives the warning simultaneously to require in time to handle pit ponding.

Detailed Description
In order to make the present invention more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
The utility model relates to a can detect buffer of elevator well pit water level, as shown in fig. 1, it includes buffer body 1, and one side of buffer body 1 is fixed with switch bracket 2, is fixed with water level detection device assembly 3 on the switch bracket 2. The water level detection device assembly 3 comprises a buoy 4 and a potentiometer, and the potentiometer is connected with the buoy 4 and an alarm device.
The buffer body 1 comprises a fixed sleeve and a movable rod arranged in the fixed sleeve. The longitudinal rod 5 is arranged on one side of the buffer body 1, the upper end of the longitudinal rod 5 is fixed on one side of the top end of the movable rod, and the lower end of the longitudinal rod 5 penetrates through the switch bracket 2 and is in contact with the switch 6; the switch bracket 2 is fixed on the outer side of the fixed sleeve. The longitudinal rod 5 serves to trigger the switch 6 when the damper is in operation.
As shown in fig. 2 to 5, the switch bracket 2 is of an integral structure; the switch bracket 2 is provided with an arc-shaped groove 25 which is connected with the outer wall of the buffer body 1 in a matching way. The switch bracket 2 comprises a first plate 21 and a second plate 22 connected with the first plate 21, the first plate 21 and the second plate 22 are provided with bending angles, a first hole 23 is formed in the middle of the first plate 21, a second hole 24 is formed in the middle of the upper portion of the second plate 22, and a third hole 26 used for installing the water level detection device assembly 3 is formed in the outer side of the second plate 22. Circular arc-shaped grooves 25 are provided on the first plate 21 and on the upper portion of the second plate 22.
The utility model discloses an installation as follows:
the utility model provides a water level detection device assembly 3 installs on buffer body 1's switch support 2, is through setting up 2 diameter 7 mm's third hole 26 on switch support 2 and fixes water level detection device assembly 3 on switch support 2 with 2M 6 bolts as the interface.
The working process of the utility model is as follows:
the buoy 4 for displaying the height of the water level rises along with the rise of the water level, and the rise of the buoy 4 drives the change of the resistance value of the potentiometer of the water level detection device assembly 3, so that an output signal changes, and the change of the resistance value and the position of the water level are set to be in a certain proportional relation (the specific proportion is set according to the requirement on the site), so that the water level of a well pit can be effectively detected, a safe water level is set, and when the water level exceeds the water level, the system gives an alarm. Therefore, the elevator components can be ensured to work safely, and the normal operation of the elevator is ensured.
The water level detecting device assembly 3 is commercially available, and its specific information is as follows: the model is as follows: 4660782, name: oil flotation, manufacturer: HITACHI/Hitachi.
