Description
Technical Field
[0001] The present application relates to the field of building construction, and in particular to an elevator protective foundation pit structure. Background Art
[0002] An elevator is a type of transportation equipment that can transport pedestrians and goods vertically up and down. When the elevator is in operation, it is generally composed of a traction motor, a power supply system, a speed feedback device, a motor speed control device, etc. The elevator runs vertically in the elevator shaft. The location of the elevator is generally determined during construction, and then space for the elevator shaft is reserved at the location where the elevator is to be installed, and then the size of the elevator shaft is determined according to the size of the elevator to be installed.
[0003] Elevators in high-rise buildings generally have negative floors. In this case, the elevator shaft will be set at a depth below the ground. During long-term use, since the elevator shaft is a nearly closed environment and is located underground, humid air will condense into water in the elevator shaft, causing water accumulation in the elevator shaft. It is also possible that underground water will seep into the elevator shaft. The accumulated water will accumulate in the elevator shaft and is not easy to discharge. The elevator shaft will be soaked in water, and elevators are precision electronic machinery. They may malfunction when encountering water. This needs further improvement. Utility Model Content
[0004] The purpose of the present application is to solve the problem raised in the above-mentioned background technology that the accumulated water will accumulate in the elevator shaft and is not easy to be discharged, the elevator shaft will be soaked by the accumulated water, and the elevator is a precision electronic machine and may malfunction when encountering water. The present application provides an elevator protection pit structure.
[0005] In order to achieve the above-mentioned purpose, this application specifically adopts the following technical solutions:
[0006] An elevator protection pit structure comprises an elevator shaft bottom, an elevator shaft wall is fixed on the elevator shaft bottom, a buffer hammer is fixed on the elevator shaft bottom; a drainage component is arranged on the elevator shaft wall, and a moisture removal component is arranged on the elevator shaft wall.
[0007] By adopting the above technical scheme, water droplets condense on the bottom and walls of the elevator shaft due to humid air during use, and the humid air in the bottom of the elevator shaft is extracted by using the dehumidification component. When water accumulates in the bottom of the elevator shaft due to water seepage, the drainage component is started to drain the accumulated water in the bottom of the elevator shaft, thereby reducing the possibility of the bottom of the elevator shaft being soaked by water and reducing the possibility of the elevator being damaged by contact with accumulated water and humid air.
[0008] Furthermore, the drainage component includes a drainage well, which is opened at the bottom of the elevator shaft. A drainage pipe is opened on the wall of the elevator shaft, and the drainage pipe is connected to the drainage well. A liquid level sensor is fixed in the drainage well, and the drainage pipe leads to the ground and is connected to a drainage pump.
[0009] By adopting the above technical solution, the accumulated water flows into the drainage well below the bottom of the elevator shaft, triggering the liquid level sensor. The control panel controls the drainage pump to pump the accumulated water out of the drainage pipe, thereby reducing the possibility of water accumulation at the bottom of the elevator shaft.
[0010] Furthermore, a one-way check valve is arranged in the drain pipe, and the one-way check valve is one-way penetrating.
[0011] By adopting the above technical solution, the one-way check valve blocks the ground water from flowing back to the bottom of the elevator shaft, thereby preventing the accumulated water on the ground from flowing to the bottom of the elevator shaft.
[0012] Furthermore, an anti-debris net is fixed at the bottom of the elevator shaft, the anti-debris net corresponds to the drainage shaft, and the anti-debris net is arranged at an angle.
[0013] By adopting the above technical solution, the anti-trash net blocks the garbage, thereby reducing the possibility of the drainage pipe and the drainage well being blocked.
[0014] Furthermore, a drainage surface is fixed at the bottom of the elevator shaft, and the drainage surface is inclined toward the drainage shaft.
[0015] By adopting the above technical solution, the accumulated water flows along the slope of the drainage surface to the drainage well, thereby reducing the possibility of residual water at the bottom of the elevator well.
[0016] Furthermore, the dehumidification component includes an exhaust shaft opened on the elevator shaft wall, an exhaust pipe is provided on the elevator shaft wall, the exhaust pipe is connected to the exhaust shaft, the exhaust pipe leads to the ground and is connected to the exhaust motor, a humidity sensor is fixed on the elevator shaft wall, and the humidity sensor is higher than the liquid level sensor.
[0017] By adopting the above technical solution, the exhaust motor uses the exhaust pipe and the exhaust shaft to extract the humid air at the bottom of the elevator shaft and discharge it to the ground, thereby reducing the possibility of humid air condensing into water droplets and causing water accumulation.
[0018] Furthermore, a protective net is fixed on the elevator shaft wall, and the protective net corresponds to the exhaust shaft.
[0019] By adopting the above technical solution, the protective net blocks the garbage at the bottom of the elevator shaft, thereby reducing the possibility of the extraction pipe being blocked.
[0020] In summary, the present application includes at least one of the following beneficial effects:
[0021] 1. In the present application, the accumulated water is allowed to flow into a drainage well below the bottom of the elevator shaft. The accumulated water in the drainage well then triggers a liquid level sensor. The liquid level sensor transmits a signal to a control panel on the ground. The control panel controls a drainage pump to pump the accumulated water out of the drainage pipe, thereby achieving the purpose of timely draining the accumulated water at the bottom of the elevator shaft, reducing the possibility of the bottom of the elevator shaft being soaked for a long time, and reducing the possibility of damage to the elevator caused by contact with accumulated water.
[0022] 2. This application allows the accumulated water to flow along the slope of the drainage surface to the drainage well, and at the same time the anti-debris net blocks the garbage, so that the accumulated water at the bottom of the elevator shaft can enter the drainage well, reducing the residual accumulated water and reducing the blockage of the drainage pipe.

[0028] The following is combined with Figure 1-3 This application is described in further detail.
[0029] An embodiment of the present application discloses an elevator protective foundation pit structure.
[0030] Reference Figure 1 , Figure 2 and Figure 3, an elevator protection pit structure, including an elevator shaft bottom 2, an elevator shaft wall 1 is fixed on the elevator shaft bottom 2, and a buffer hammer 5 is fixed on the elevator shaft bottom 2; a drainage component 3 is arranged on the elevator shaft wall 1, and a dehumidification component 4 is arranged on the elevator shaft wall 1. When the elevator shaft bottom and the motor shaft wall are poured with concrete at the construction site, the positions of the drainage component 3 and the dehumidification component 4 are reserved during the pouring, and then the drainage component 3 and the dehumidification component 4 are installed. When the elevator shaft bottom 2 and the elevator shaft wall 1 are used, water droplets condense on the elevator shaft bottom 2 and the elevator shaft wall 1 due to humid air during use. At this time, the dehumidification component is used to extract the humid air of the elevator shaft bottom 2. When the elevator shaft bottom 2 accumulates water due to water seepage, the drainage component 3 is started to discharge the accumulated water of the elevator shaft bottom 2. By using the dehumidification component 4 and the drainage component 3 to discharge the humid air and accumulated water of the elevator shaft bottom 2, the possibility of the elevator shaft bottom 2 being soaked by water is reduced, and the possibility of the elevator being damaged by contact with accumulated water and humid air is reduced.
[0031] Reference Figure 1 and Figure 3 The drainage assembly 3 includes a drainage well 31, which is opened at the bottom of the elevator shaft 2. A drainage pipe 32 is opened on the elevator shaft wall 1. The drainage pipe 32 is connected to the drainage well 31. A liquid level sensor 33 is fixed in the drainage well 31. The drainage pipe 32 leads to the ground and is connected to a drainage pump. When there is water accumulation at the bottom of the elevator shaft 2, the accumulated water flows into the drainage well 31 which is lower than the bottom of the elevator shaft. Then, the accumulated water in the drainage well 31 triggers the liquid level sensor 33. The liquid level sensor 33 transmits a signal to the control panel on the ground. The control panel controls the drainage pump to pump the accumulated water out of the drainage pipe 32. The accumulated water at the bottom of the elevator shaft 2 is drained by using the drainage pipe 32, thereby reducing the possibility of water accumulation at the bottom of the elevator shaft.
[0032] Reference Figure 3 A one-way check valve 6 is arranged in the drainage pipe 32, and the one-way check valve 6 is one-way through. When the drainage pump uses the drainage pipe 32 to absorb water, it absorbs water from a low place to a high place. The accumulated water flows through the drainage pipe 32 and passes through the one-way check valve 6. The accumulated water passes normally. When the drainage stops, the one-way check valve 6 blocks the ground water from flowing back to the bottom of the elevator shaft 2. The one-way check valve 6 blocks the accumulated water on the ground from flowing to the bottom of the elevator shaft.
[0033] Reference Figure 1 , Figure 2 and Figure 3 The elevator shaft bottom is fixed with an anti-clutter net 7, which corresponds to the drainage well 31 and is tilted. Garbage may appear at the elevator shaft bottom 2, and under the action of water flow, the garbage will flow to the drainage well 31, and the anti-clutter net 7 will block the garbage. By blocking the drainage well 31 with the anti-clutter net 7, the possibility of the drainage pipe 32 and the drainage well 31 being blocked is reduced.
[0034] Reference Figure 1 and Figure 3 A drainage surface 8 is fixed at the bottom of the elevator shaft 2, and the drainage surface 8 is inclined toward the drainage well 31. When water accumulates at the bottom of the elevator shaft 2, the accumulated water flows along the inclined surface of the drainage surface 8 to the drainage well 31, and the accumulated water flows to the drainage well 31 through the drainage surface 8, thereby reducing the possibility of residual water accumulation at the bottom of the elevator shaft 2.
[0035] Reference Figure 1 and Figure 3 The moisture removal component 4 includes an exhaust shaft 41 opened on the elevator shaft wall 1, an exhaust pipe 42 is arranged on the elevator shaft wall 1, the exhaust pipe 42 is connected to the exhaust shaft 41, the exhaust pipe 42 leads to the ground and is connected to the exhaust motor, and a humidity sensor 43 is fixed on the elevator shaft wall 1, and the humidity sensor 43 is higher than the liquid level sensor 33. When the air at the bottom of the elevator shaft 2 is relatively humid, the humid air triggers the humidity sensor 43, and the humidity sensor 43 transmits a signal to the controller on the ground, and the controller controls the exhaust motor to start, and the exhaust motor uses the exhaust pipe 42 and the exhaust shaft 41 to extract the humid air at the bottom of the elevator shaft 2 and discharge it to the ground, and the humid air is discharged to the ground by using the exhaust fan, thereby reducing the possibility of condensation of humid air into water droplets and causing water accumulation.
[0036] Reference Figure 1 and Figure 3 A protective net 9 is fixed on the elevator shaft wall 1, and the protective net 9 corresponds to the exhaust shaft 41. When the exhaust fan starts to extract humid air using the exhaust pipe 42 and the exhaust shaft 41, the protective net 9 blocks the garbage at the bottom of the elevator shaft 2, thereby reducing the possibility of the extraction pipe being blocked.
[0037] Working principle: During construction at the construction site, the elevator shaft bottom and motor shaft wall are poured with concrete. During the pouring, the positions of the drainage component 3 and the moisture-removing component 4 are reserved, and then the drainage component 3 and the moisture-removing component 4 are installed. When there is water accumulation at the elevator shaft bottom 2, the accumulated water flows into the drainage well 31 below the elevator shaft bottom, and then the accumulated water in the drainage well 31 triggers the liquid level sensor 33, and the liquid level sensor 33 transmits a signal to the control panel on the ground. The control panel controls the drainage pump to extract the accumulated water from the drainage pipe 32. Then, when the air at the elevator shaft bottom 2 is relatively humid, the humid air triggers the humidity sensor 43, and the humidity sensor 43 transmits a signal to the controller on the ground. The controller controls the exhaust motor to start, and the exhaust motor uses the exhaust pipe 42 and the exhaust well 41 to extract the humid air at the elevator shaft bottom 2 and discharge it to the ground.
