Description

Technical Field

[0001] The utility model relates to the technical field of elevator water retaining devices, in particular to an automatic water retaining device for an elevator entrance. Background Art

[0002] When water leaks unexpectedly in the building or when there is a typhoon or heavy rain, the issue of water blocking at the elevator entrance becomes particularly important. This is because water may quickly accumulate and flow back into the elevator shaft through the elevator entrance in an emergency or in severe weather conditions. Once water enters the elevator shaft, it will pose a serious threat to the elevator equipment.

[0003] First, water flow can cause short circuits in the electrical equipment in the elevator shaft. As a complex mechatronic system, the elevator contains a large number of circuit boards and electrical components. When water flow contacts these devices, it will cause an electrical short circuit, causing the elevator to lose control and even cause safety accidents such as fire.

[0004] Secondly, water flow can also damage the mechanical parts of the elevator. The key parts of the elevator, such as the transmission system, guide rails, and door machines, are all precision mechanical structures and are very sensitive to water intrusion. Once water flows into the elevator shaft, these parts may be damaged due to rust, corrosion, or lubrication failure, seriously affecting the normal operation of the elevator.

[0005] In addition, water backflow into the elevator shaft will also cause water accumulation in the elevator shaft. The accumulated water will not only make the elevator shaft environment humid, but also may cause mold growth, posing a potential threat to elevator equipment and passenger health. At the same time, the accumulated water may also affect the load-bearing structure of the elevator shaft and reduce the safety of the elevator. Summary of the invention

[0026] The bottom shell 1 is provided with a cavity with an upper opening, and a water intercepting ditch 8 is provided on the wall at one end of the bottom shell 1, the upper opening of the water intercepting ditch 8 is located at the upper end surface of the end wall of the bottom shell 1, and the lower opening of the water intercepting ditch 8 is located on the inner side of the end wall of the bottom shell 1. Water can flow into the cavity of the bottom shell 1 through the upper opening of the water intercepting ditch 8.

[0027] In the optimized solution, the lower end opening of the intercepting ditch 8 is located at the inner lower end portion of the end wall of the bottom shell 1 .

[0028] A flip cover plate 2 is installed on the wall at the other end of the bottom shell 1, one end of the flip cover plate 2 is rotatably matched with the two side walls of the bottom shell 1 through an axis, and the flip cover plate 2 is connected to the bottom shell 1 through a flip mechanism 6. The flip mechanism 6 can drive the flip cover plate 2 to rotate, so that the flip cover plate 2 is buckled at the upper end opening position of the cavity of the bottom shell 1 when not in use. When the flip cover plate 2 needs to be used to block water, the flip mechanism 6 is started to drive the flip cover plate 2 to rotate 90°, blocking it at the elevator entrance, thereby blocking part of the water flow from entering the elevator.

[0029] In the optimized solution, a sealing baffle 14 is installed at one end of the bottom shell 1, the lower end of the sealing baffle 14 is connected to the bottom shell 1, and the upper end protrudes a portion of the upper end surface of the bottom shell 1 to block the gap at the connection between the flip cover 2 and the bottom shell 1. When the flip cover 2 is flipped 90°, the flip cover 2 can be tightly attached to the sealing baffle 14.

[0030] In this embodiment, side sealing strips 13 are installed on both sides of the back of the flip cover 2. When the flip cover 2 is flipped 90 degrees, it can fit on the walls on both sides of the elevator entrance to prevent water from entering the elevator entrance.

[0031] The flip mechanism 6 is a hydraulic telescopic rod, the lower end of the outer tube of the hydraulic telescopic rod is rotatably connected to the inner wall of the bottom shell 1, and the upper end of the inner rod of the hydraulic telescopic rod is hinged to the lower end surface of the flip cover 2. The hydraulic telescopic rod is connected to a hydraulic station, and the hydraulic station can drive the hydraulic telescopic rod to extend and retract. The hydraulic station is an existing device, and its specific structure is not repeated here.

[0032] In the optimized solution, the two inner side walls of the bottom shell 1 are respectively connected to a hydraulic telescopic rod, and two ear plates are symmetrically installed on the lower end wall of the flip cover plate 2, and the hydraulic telescopic rod is hinged to the corresponding ear plates respectively.

[0033] An inner support plate 5 is installed in the cavity of the bottom shell 1, and the inner support plate 5 is located below the flip cover 2. When the flip cover 2 is flipped up, the inner support plate 5 can protect pedestrians and prevent them from falling into the cavity of the bottom shell 1.

[0034] The inner support plate 5 is provided with a plurality of evenly arranged long strip water leakage holes, so that water can be discharged into the cavity of the bottom shell 1 through the long strip water leakage holes, and water accumulates on the inner support plate 5 .

[0035] like Figure 4 As shown, in this embodiment, the outer cylinder of the hydraulic telescopic rod is vertically connected to the connecting shaft, and two guide plates 7 are fixedly and vertically installed on the lower end surface of the inner support plate 5. The two guide plates 7 are respectively provided with long strip guide through holes, and the connecting shaft passes through the long strip guide through holes on the guide plates 7. When the hydraulic telescopic rod drives the flip cover plate 2 to flip, it can rotate upward at the same time, and drive the inner support plate 5 to move upward through the connecting shaft and the guide plate 7.

[0036] like Figure 3 As shown, two pairs of symmetrically distributed guide blocks 11 are installed on the bottom wall of the cavity of the bottom shell 1, and guide holes are provided on the guide blocks 11. Guide rods 10 corresponding to the guide blocks 11 are vertically installed on the inner support plate 5. The guide rods 10 are inserted into the guide holes of the guide blocks 11 and connected to the bottom of the guide holes through springs. When the flip cover 2 is buckled in the opening position of the bottom shell 1, the inner support plate 5 compresses the spring through the guide rods 10.

[0040] The alarm device 4 is an audible and visual alarm device 4 .

[0041] The operation process is as follows: when the utility model is not in operation, the flip cover 2 is buckled in the opening position of the bottom shell 1. Figure 5 As shown, when water flows into the cavity from the intercepting ditch 8 of the bottom shell 1, the liquid level sensor 9 senses and works, and the hydraulic sensor transmits a signal to the hydraulic station. The hydraulic station extends the hydraulic telescopic rod, driving the flip cover plate 2 to flip 90°, so that the flip cover plate 2 is blocked at the elevator entrance. When the hydraulic telescopic rod drives the flip cover plate 2 to flip, it can also rotate upward at the same time, driving the inner support plate 5 to move upward through the connecting shaft and the guide plate 7. At this time, the spring gradually resets, playing a certain supporting role for the inner support plate 5. When the liquid level sensor 9 senses and works, it transmits the signal to the alarm 4 at the same time, and the alarm 4 sounds an alarm.

[0042] It should be noted that the specific embodiments of the present invention have been described in detail.
