Description
Technical Field
[0001] The invention belongs to the technical field of home elevator pit safety, and in particular relates to a home villa elevator pit water ingress safety protection device. Background Art
[0002] With the rapid development of modern urban construction, home elevators in home villas are favored by more and more families. However, as the supporting and fixing structure of the elevator equipment, the elevator pit is often easily affected by the external environment. Factors such as rainwater infiltration and rising groundwater levels may cause water to enter the elevator pit. Long-term water inflow will not only increase the humidity and accumulate water inside the pit, but also cause safety hazards such as equipment damage and electrical short circuits, seriously affecting the normal operation and service life of the elevator.
[0003] In order to solve this problem, a drainage system is usually installed in the traditional elevator pit to remove the water in the pit. Screw elevators are commonly used in home elevators, but due to the limitations of home elevators, the depth of the pit is limited. When there is water in the pit, it needs to be discharged in time. The existing drainage system cannot drain the water in the pit, causing the pit to be in a humid environment for a long time. Even if there is no water in the pit, the humidity in the pit is higher in humid places, so the equipment in the pit is in a humid environment for a long time, which seriously affects the operation and service life of the elevator; at the same time, due to the limitation of the pit depth, the buffer device installed in the pit to protect the elevator from falling has limited protection ability for the elevator, which poses a safety hazard.
[0004] The information disclosed in this background technology section is only intended to enhance the understanding of the overall background of the invention and should not be regarded as an acknowledgment or any form of suggestion that the information constitutes the prior art already known to a person skilled in the art. Summary of the invention
[0005] The purpose of the present invention is to provide a water ingress safety protection device for a household villa elevator pit, which can solve the problem that the long-term tidal environment in the pit affects the operation and service life of the elevator and the problem that the buffer device has limited elevator protection ability and poses a safety hazard.
[0006] In order to achieve the above object, a technical solution provided by a specific embodiment of the present invention is as follows:
[0007] A water ingress safety protection device for a household villa elevator pit, comprising:
[0008] The elevator body comprises an elevator shaft and a car. The car is movably installed in the elevator shaft. An elevator pit is arranged at the bottom of the elevator shaft. The elevator pit is used for installing the elevator buffer device and related components.
[0009] The pneumatic compression assembly includes a piston plate, which is fixedly connected to the outer side wall of the bottom of the car, so that the piston plate can be driven to move when the car moves. The side of the piston plate away from the car abuts against the inner side wall of the elevator shaft, so that the bottom of the car and the piston plate can form a seal in the elevator shaft. When the car drives the piston plate to move downward in the elevator shaft, the air in the elevator shaft can be compressed to flow downward, so as to squeeze the air in the elevator shaft into the elevator pit, so that the air in the elevator shaft can be circulated to purge the bottom of the elevator pit, thereby drying the accumulated water in the elevator pit that has not been drained by air flow, so that the elevator pit is in a dry state. When there is someone at home, the elevator will be used at any time. When the car is descending, the air in the elevator shaft will blow against the bottom of the elevator pit. Therefore, through the use of the car, the flow of air in the elevator shaft can be used to blow against the bottom of the elevator pit. Without the need to solve the action of external force, the bottom of the elevator pit can be dried by blowing.
[0010] The extrusion buffer assembly includes an extrusion buffer capsule, the extrusion buffer capsule is arranged in the elevator pit, the interior of the extrusion buffer capsule is arranged as a hollow structure, a partition plate is integrally formed in the extrusion buffer capsule, the partition plate divides the extrusion buffer capsule into a first installation chamber and a second installation chamber, and a plurality of buffer springs are installed in the first installation chamber and the second installation chamber. When the car moves downward, it will contact the upper surface of the extrusion buffer capsule, and when the car continues to move downward, the extrusion buffer capsule can be compressed, so that the buffer spring in the extrusion buffer capsule is compressed and drives the extrusion buffer capsule to move downward, so that the accumulated water in the elevator pit can be squeezed through the bottom of the extrusion buffer capsule, so that the accumulated water in the elevator pit can be discharged by squeezing the extrusion buffer capsule. Since multiple buffer springs are arranged in the extrusion buffer bladder, when the car contacts the extrusion buffer bladder, the extrusion buffer bladder will cushion the car when it is compressed, so that when the car is normally in use and stops at the lowest floor, the parking is stable through the buffering of the extrusion buffer bladder. At the same time, when the elevator stalls or falls, causing the car to drop rapidly, when the car contacts the extrusion buffer bladder, the buffer springs in the extrusion buffer bladder can effectively cushion the car, thereby ensuring that the car can land safely and ensuring the safety of the elevator and the people inside when the car stalls or falls.
[0011] In one or more embodiments of the present invention, a polished surface is provided on the inner side wall of the elevator shaft, a screw rod and a limit rod are fixedly installed in the elevator shaft, a drive motor is installed on the rear side wall of the car, a drive gear is threadedly connected to the screw rod, the drive motor and the drive gear are meshedly connected, and the drive motor drives the drive gear to rotate, so that the car is driven to move on the screw rod. A limit slider is fixedly connected to the rear side wall of the car, and the limit slider is slidably connected to the limit rod, and the cooperation between the limit slider and the limit rod makes the car stable when moving up and down.
[0012] In one or more embodiments of the present invention, the piston plate includes a connecting plate and a contact layer, the contact layer is fixedly connected to the outer side of the connecting plate, the connecting plate is fixedly connected to the bottom outer wall of the car, and the side of the contact layer away from the car abuts against the inner wall of the elevator shaft. The connection between the connecting plate and the outer side of the car ensures that the car can stably drive the piston plate to move, and the contact layer is provided on the outer wall of the connecting plate so that the contact layer contacts the inner wall of the elevator shaft, so that the piston plate and the elevator shaft have a relatively good sealing, and the piston plate can move up and down in the elevator shaft driven by the car, so that when the car drives the piston plate to move downward, the air in the elevator shaft is transported to the bottom of the elevator pit by compression.
[0013] In one or more embodiments of the present invention, the contact layer is made of engineering plastics, and sound-absorbing materials are added to the engineering plastics, and the engineering plastics are special engineering plastics. Since the contact layer needs to keep in contact with the inner wall of the elevator shaft when following the movement of the car, the contact layer needs to be made of a material with good wear resistance and high smoothness to ensure that the contact layer can move smoothly when in contact with the inner wall of the elevator shaft, so the contact layer is made of engineering plastics. Since there may be abnormal noise due to friction when the contact layer moves in contact with the inner wall of the elevator shaft, by adding sound-absorbing materials to the engineering plastics, it is ensured that no abnormal noise is emitted when the contact layer moves on the inner wall of the elevator shaft, thereby ensuring the quietness of the elevator during operation.
[0014] In one or more embodiments of the present invention, a pair of first sliding holes are provided on the piston plate disposed on the rear side wall of the car, the opening shape of the first sliding holes matches the cross-sectional shape of the screw rod and the limit rod, and the piston plate is slidably connected to the screw rod and the limit rod through the first sliding holes. The first sliding holes ensure that when the car drives the piston plate to move, the screw rod and the limit rod will not affect the movement of the piston plate.
[0015] In one or more embodiments of the present invention, the extrusion buffer capsule is made of a rubber material, and the rubber material includes one or more combinations of vulcanized ceramic rubber, EPDM rubber, and polyurethane elastomer. Since the extrusion buffer capsule needs to be compressed during use, the extrusion buffer capsule is made of a compressible rubber material. At the same time, since the extrusion buffer capsule needs to be placed in the elevator pit for a long time, the extrusion buffer capsule should have good anti-corrosion and wear resistance to ensure the service life. The partition plate is made of the same material as the extrusion buffer bladder, and a plurality of limit blocks are provided on the outer side walls around the extrusion buffer bladder by an integral molding manner. The side of the limit block away from the extrusion buffer bladder abuts against the inner side wall of the elevator shaft. Since the extrusion buffer bladder needs to be extruded and deformed by the car when in use, in order to allow the accumulated water in the elevator pit to flow through the gap between the extrusion buffer bladder and the inner side wall of the elevator shaft after being squeezed when the extrusion buffer bladder is extruded and deformed, a plurality of limit blocks are provided on the outer side wall of the extrusion buffer bladder. With the support of the limit blocks, when the extrusion buffer bladder is extruded and deformed, a certain gap is always maintained between the side wall of the extrusion buffer bladder and the inner side wall of the elevator shaft for the flow of accumulated water and air.
[0016] In one or more embodiments of the present invention, a plurality of the buffer springs are evenly distributed in the first installation chamber and the second installation chamber, and the buffer springs are small-diameter compression springs, and the diameter of the buffer springs is set to 10 to 30 mm. In order to improve the buffering performance of the car during stall and fall by squeezing the buffer capsule, and to ensure that the stalled or falling car can be effectively buffered by squeezing the buffer springs in the buffer capsule, the buffer spring is set to a small-diameter compression spring, and a plurality of buffer springs are provided and evenly distributed in the first installation chamber and the second installation chamber, so that the spring body is combined in the first installation chamber and the second installation chamber, which can effectively improve its range and performance, improve its elasticity, higher load capacity and better shock absorption effect, so that the buffer spring has an excellent buffering effect, thereby ensuring that the squeezing of the buffer capsule ensures the safety of the car after stalling or falling from the building.
[0017] In one or more embodiments of the present invention, a buffer device is installed at the bottom of the elevator pit, and the buffer device is a device installed in the elevator pit to buffer the stall and fall of the elevator. The buffer device includes a sleeve, a telescopic rod is slidably installed in the sleeve, a compression spring is installed in the sleeve, and the upper end of the compression spring is sleeved on the side wall of the telescopic rod. When in use, when the telescopic rod moves downward in the sleeve, the compression spring is compressed, and when the compression spring is compressed, the movement of the telescopic rod is buffered, thereby achieving buffering of the falling elevator.
[0018] In one or more embodiments of the present invention, a water-absorbing block is arranged at the bottom of the squeeze buffer capsule, and the water accumulated in the elevator pit is absorbed by the water-absorbing block, so as to reduce the influence of the accumulated water on the components installed in the elevator pit. The water-absorbing block is a sponge, and the sponge is made of high-density PVA water-absorbing sponge or polyurethane sponge material. Since the water-absorbing block is arranged in the elevator pit, in order to make the water-absorbing block be used for a long time in the elevator pit, the water-absorbing block is selected to have corrosion-resistant and wear-resistant water-absorbing sponge. A groove is arranged at the bottom of the squeeze buffer capsule, and a through hole is arranged on the water-absorbing block. The upper end of the buffer device passes through the through hole and is placed in the groove. Through the groove and the through hole, the telescopic rod is in contact with the squeeze buffer capsule, so that when the car compresses the squeeze buffer capsule, the telescopic rod can be driven to move downward in the sleeve, thereby causing the squeeze buffer capsule to move downward. When the squeeze buffer capsule moves downward, the water-absorbing block can be driven to move downward, so as to squeeze the water-absorbing block, thereby facilitating the discharge of the water absorbed in the water-absorbing block, so as to facilitate the discharge of the accumulated water.
[0019] In one or more embodiments of the present invention, a drainage hole is provided at the bottom of the side wall of the elevator shaft, and a water pipe is fixedly connected to the outer side wall of the elevator shaft at the drainage hole, and the water pipe is connected to the drainage system in the villa, and the distance between the drainage hole and the bottom of the elevator pit is less than the distance between the elevator car and the bottom of the elevator pit when the car is at the bottom. When the accumulated water in the elevator pit is squeezed by squeezing the buffer capsule, the accumulated water will flow through the gap between the squeezing buffer capsule and the inner side wall of the elevator shaft. Since the squeezed water has pressure, and the seal formed between the piston plate and the bottom wall plate of the car and the inner side wall of the elevator shaft will block the upward flow of the accumulated water, so that the accumulated water will enter the water pipe through the drainage hole, so that the accumulated water is transported to the drainage system through the water pipe for external discharge, thereby realizing the external discharge of the accumulated water in the elevator pit. At the same time, when the car moves downward once, the accumulated water in the elevator pit can be discharged once by squeezing, so that the accumulated water in the elevator pit can be discharged without the help of drainage equipment.
[0020] Compared with the prior art, the present invention has the following advantages:
[0021] 1. The present invention is provided with a pneumatic compression assembly at the bottom of the elevator car. When the elevator car moves downward, the piston plate can be driven to move downward. Through the action of the elevator car bottom and the piston plate, the air in the elevator shaft can be compressed, so that the air in the elevator shaft moves downward with the downward movement of the elevator car. The air in the elevator shaft will be compressed into the pit, so that the pit is dried by air flow, so that the pit is in a dry state, and then the equipment in the pit is in a dry environment, which ensures the safety of the elevator operation and increases the service life;
[0022] 2. The present invention is provided with an extrusion buffer assembly. When water accumulates in the elevator pit, the elevator car moves from the upper floor to the lower floor, and the elevator car compresses the extrusion buffer capsule, which compresses the water-absorbing block at the bottom, so that the accumulated water in the pit is squeezed and discharged through the drainage holes arranged on the side wall of the elevator shaft, so that the accumulated water in the elevator can be discharged through the reciprocating motion of the elevator, making it convenient to discharge the accumulated water in the pit, and having good practicality;
[0023] 3. The extrusion buffer assembly provided in the present invention has a spring body composed of multiple springs in the extrusion buffer bag so that the spring body can buffer the stalled or falling elevator, thereby greatly improving the buffering performance of the buffer device, so as to ensure that the elevator car is effectively buffered by the extrusion buffer bag when the elevator stalls or falls, thereby ensuring the safety of the elevator and the people inside when the elevator stalls or falls.

DETAILED DESCRIPTION
[0035] In order to enable those skilled in the art to better understand the technical solutions in the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work should fall within the scope of protection of the present invention.
[0036] like Figure 1 to Figure 6 As shown, a household villa elevator pit water ingress safety protection device in one embodiment of the present invention includes an elevator body 1, a pneumatic compression component 2 and an extrusion buffer component 3.
[0037] like Figure 1 to Figure 6 As shown, the elevator body 1 includes an elevator shaft 11 and a car 12. The car 12 is movably installed in the elevator shaft 11. An elevator pit 18 is provided at the bottom of the elevator shaft 11. The elevator pit 18 is used for installing the elevator buffer device and related components.
[0038] like Figure 2As shown, a polished surface is provided on the inner side wall of the elevator shaft 11, a screw rod 13 and a limit rod 14 are fixedly installed in the elevator shaft 11, a drive motor 15 is installed on the rear side wall of the car 12, a drive gear 16 is threadedly connected to the screw rod 13, the drive motor 15 and the drive gear 16 are meshedly connected, and the drive motor 15 drives the drive gear 16 to rotate, so that the car 12 is driven to move on the screw rod 13. A limit slider 17 is fixedly connected to the rear side wall of the car 12, and the limit slider 17 is slidably connected to the limit rod 14. The cooperation between the limit slider 17 and the limit rod 14 makes the car 12 stable when moving up and down.
[0039] like Figure 2 to Figure 6 As shown, the pneumatic compression assembly 2 includes a piston plate 21, which is fixedly connected to the outer side wall of the bottom of the car 12, so that the piston plate 21 can be driven to move when the car 12 moves. The side of the piston plate 21 away from the car 12 abuts against the inner side wall of the elevator shaft 11, so that the bottom of the car 12 and the piston plate 21 can form a seal in the elevator shaft 11. When the car 12 drives the piston plate 21 to move downward in the elevator shaft 11, the air in the elevator shaft 11 can be compressed to flow downward, so as to squeeze the air in the elevator shaft 11 into the elevator pit 18, so that the air in the elevator shaft 11 is circulated to purge the bottom of the elevator pit 18, thereby drying the undrained water in the elevator pit 18 by air flow, so that the elevator pit 18 is in a dry state. When someone is at home, the elevator will be used at any time. When the car 12 is descending, the air in the elevator shaft 11 will blow the bottom of the elevator pit 18. Therefore, through the use of the car 12, the flow of air in the elevator shaft 11 can be used to blow the bottom of the elevator pit 18. Without the need to solve the action of external force, the bottom of the elevator pit 18 can be dried by blowing.
[0040] It should be noted that in order to compress the air in the elevator shaft 11 through the seal formed by the car 12 and the piston plate 21, the switch doors set on each floor of the elevator should have good sealing when closed to prevent the air in the elevator shaft 11 from being compressed and leaking through the switch doors.
[0041] like Figure 7As shown, the piston plate 21 includes a connecting plate 2101 and a contact layer 2102, the contact layer 2102 is fixedly connected to the outer side of the connecting plate 2101, the connecting plate 2101 is fixedly connected to the bottom outer wall of the car 12, and the side of the contact layer 2102 away from the car 12 abuts against the inner wall of the elevator shaft 11. Through the connection between the connecting plate 2101 and the outer side of the car 12, it is ensured that the car 12 can stably drive the piston plate 21 to move, and by arranging the contact layer 2102 on the outer wall of the connecting plate 2101, the contact layer 2102 is in contact with the inner wall of the elevator shaft 11, so that the piston plate 21 and the elevator shaft 11 have a relatively good sealing, and the piston plate 21 can move up and down in the elevator shaft 11 under the drive of the car 12, so that when the car 12 drives the piston plate 21 to move downward, the air in the elevator shaft 11 is transported to the bottom of the elevator pit 18 by compression.
[0042] Preferably, the contact layer 2102 is made of engineering plastics, and sound-absorbing materials are added to the engineering plastics, and the engineering plastics are special engineering plastics. Since the contact layer 2102 needs to keep in contact with the inner wall of the elevator shaft 11 when following the movement of the car 12, the contact layer 2102 needs to be made of a material with good wear resistance, and at the same time needs to be smooth, so as to ensure that the contact layer 2102 can move smoothly when in contact with the inner wall of the elevator shaft 11, so the contact layer 2102 is made of engineering plastics. Since the contact layer 2102 may make abnormal noises due to friction when moving in contact with the inner wall of the elevator shaft 11, by adding sound-absorbing materials to the engineering plastics, it is ensured that the contact layer 2102 does not make abnormal noises when moving on the inner wall of the elevator shaft 11, and the quietness of the elevator is ensured when the elevator is running.
[0043] Specifically, a pair of first sliding holes are provided on the piston plate 21 disposed on the rear side wall of the car 12, and the opening shape of the first sliding holes matches the cross-sectional shape of the screw rod 13 and the limit rod 14, and the piston plate 21 is slidably connected to the screw rod 13 and the limit rod 14 through the first sliding holes. The first sliding holes ensure that when the car 12 drives the piston plate 21 to move, the screw rod 13 and the limit rod 14 will not affect the movement of the piston plate 21.
[0044] like Figure 3 to Figure 6As shown, the extrusion buffer assembly 3 includes an extrusion buffer capsule 31, which is arranged in the elevator pit 18. The interior of the extrusion buffer capsule 31 is set as a hollow structure. A partition plate 32 is integrally formed in the extrusion buffer capsule 31. The partition plate 32 divides the extrusion buffer capsule 31 into a first installation chamber 33 and a second installation chamber 34. A plurality of buffer springs 35 are installed in the first installation chamber 33 and the second installation chamber 34. When the car 12 moves downward, it will contact the upper surface of the extrusion buffer capsule 31. When the car 12 continues to move downward, the extrusion buffer capsule 31 can be compressed, so that the buffer spring 35 in the extrusion buffer capsule 31 is compressed and drives the extrusion buffer capsule 31 to move downward, so that the accumulated water in the elevator pit 18 can be squeezed through the bottom of the extrusion buffer capsule 31, so that the accumulated water in the elevator pit 18 can be discharged by squeezing the extrusion buffer capsule 31. Since a plurality of buffer springs 35 are arranged in the extrusion buffer capsule 31, when the car 12 contacts the extrusion buffer capsule 31, the extrusion buffer capsule 31 will be compressed to buffer the car 12, so that when the car 12 is in normal use, the parking is stable through the buffering of the extrusion buffer capsule 31 when it is docked at the bottom floor. At the same time, when the elevator stalls or falls, causing the car 12 to drop rapidly, when the car 12 contacts the extrusion buffer capsule 31, the buffer springs 35 in the extrusion buffer capsule 31 can effectively buffer the car 12, thereby ensuring that the car 12 can land safely and ensuring the safety of the elevator and the people inside when the car 12 stalls or falls.
[0045] like Figure 6 and Figure 8As shown, the extrusion buffer capsule 31 is made of rubber material, and the rubber material includes one or more combinations of vulcanized ceramic rubber, EPDM rubber and polyurethane elastomer. Since the extrusion buffer capsule 31 needs to be compressed when in use, the extrusion buffer capsule 31 is made of a compressible rubber material. At the same time, since the extrusion buffer capsule 31 needs to be placed in the elevator pit 18 for a long time, the extrusion buffer capsule 31 should have good anti-corrosion and wear resistance to ensure the service life. The partition plate 32 is made of the same material as the extrusion buffer bladder 31. A plurality of limit blocks 315 are provided on the outer side walls around the extrusion buffer bladder 31 by an integrated molding manner. The side of the limit block 315 away from the extrusion buffer bladder 31 abuts against the inner side wall of the elevator shaft 11. Since the extrusion buffer bladder 31 needs to be extruded and deformed by the car 12 when in use, in order to allow the accumulated water in the elevator pit 18 to flow through the gap between the extrusion buffer bladder 31 and the inner side wall of the elevator shaft 11 after being squeezed when the extrusion buffer bladder 31 is extruded and deformed, a plurality of limit blocks 315 are provided on the outer side wall of the extrusion buffer bladder 31. With the support of the limit blocks 315, when the extrusion buffer bladder 31 is extruded and deformed, a certain gap is always maintained between the side wall of the extrusion buffer bladder 31 and the inner side wall of the elevator shaft 11 for the flow of accumulated water and air.
[0046] like Figure 3 and Figure 8 As shown, a plurality of buffer springs 35 are evenly distributed in the first installation chamber 33 and the second installation chamber 34, and the buffer spring 35 adopts a small-diameter compression spring, and the diameter of the buffer spring 35 is set to 10-30 mm. In order to improve the buffering performance of the car 12 when the squeeze buffer capsule 31 stalls and falls, and ensure that the buffer spring 35 in the squeeze buffer capsule 31 can effectively buffer the stalled or falling car 12, the buffer spring 35 is set to a small-diameter compression spring, and the buffer spring 35 is provided with a plurality of and evenly distributed in the first installation chamber 33 and the second installation chamber 34, so that the spring body is combined in the first installation chamber 33 and the second installation chamber 34, which can effectively improve its range and performance, improve its elasticity, higher load capacity and better shock absorption effect, so that the buffer spring 35 has an excellent buffering effect, thereby ensuring that the squeeze buffer capsule 31 ensures the safety of the car 12 after the stall or fall after falling.
[0047] like Figure 3 to Figure 6As shown, a buffer device 39 is installed at the bottom of the elevator pit 18. The buffer device 39 is a device originally installed in the elevator pit 18 to buffer the stall and fall of the elevator. The buffer device 39 includes a sleeve 310, in which a telescopic rod 311 is slidably installed, and a compression spring 312 is installed in the sleeve 310. The upper end of the compression spring 312 is sleeved on the side wall of the telescopic rod 311. When in use, when the telescopic rod 311 moves downward in the sleeve 310, the compression spring 312 is compressed. When the compression spring 312 is compressed, the movement of the telescopic rod 311 is buffered, thereby achieving buffering of the elevator.
[0048] like Figure 3 to Figure 6 As shown, a water-absorbing block 36 is provided at the bottom of the squeeze buffer bladder 31, and the water-absorbing block 36 is provided to absorb the accumulated water in the elevator pit 18, thereby reducing the influence of the accumulated water on the components installed in the elevator pit 18. The water-absorbing block 36 is a sponge, and the sponge is made of a high-density PVA water-absorbing sponge or a polyurethane sponge material. Since the water-absorbing block 36 is provided in the elevator pit 18, in order to enable the water-absorbing block 36 to be used for a long time in the elevator pit 18, the water-absorbing block 36 is a water-absorbing sponge with corrosion resistance and wear resistance.
[0049] Furthermore, if Figure 8 As shown, a groove 37 is provided at the bottom of the extrusion buffer capsule 31, a through hole 38 is provided on the water absorption block 36, and the upper end of the buffer device 39 passes through the through hole 38 and is placed in the groove 37. Through the groove 37 and the through hole 38, the telescopic rod 311 is in contact with the extrusion buffer capsule 31, so that when the car 12 compresses the extrusion buffer capsule 31, the telescopic rod 311 can be driven to move downward in the sleeve 310, thereby causing the extrusion buffer capsule 31 to move downward. When the extrusion buffer capsule 31 moves downward, the water absorption block 36 can be driven to move downward, so as to squeeze the water absorption block 36, thereby facilitating the discharge of the water absorbed in the water absorption block 36, so as to facilitate the discharge of the accumulated water.
[0050] Preferably, in order to make the deformation of the extrusion buffer capsule 31 in the elevator pit 18 stable after being squeezed and not displaced, a second sliding hole for slidingly connecting with the screw 13 and the limit rod 14 is provided on the rear side wall of the extrusion buffer capsule 31, and the extrusion buffer capsule 31 can be compressed and stretched by the guidance of the screw 13 and the limit rod 14 through the guidance of the second sliding hole, so as to ensure the stability of the position of the extrusion buffer capsule 31 when installed in the elevator pit 18. At the same time, when there is too much water in the pit, in order to make the extrusion buffer capsule 31 always above the water surface, a floating plate is provided at the bottom of the extrusion buffer capsule 31, so that the extrusion buffer capsule 31 can move upward under the buoyancy of the accumulated water. At the same time, since personnel need to enter the elevator pit 18 during elevator maintenance, the extrusion buffer capsule 31 slides in the screw 13 and the limit rod 14 so that the extrusion buffer capsule 31 can be lifted, so that personnel can enter the elevator pit 18 to perform elevator maintenance work.
[0051] like Figure 8 As shown, a drainage hole 313 is provided at the bottom of the side wall of the elevator shaft 11, and a water pipe 314 is fixedly connected to the outer wall of the elevator shaft 11 at the drainage hole 313. The water pipe 314 is connected to the drainage system in the villa, and the distance between the drainage hole 313 and the bottom of the elevator pit 18 is less than the distance between the elevator car 12 and the bottom of the elevator pit 18 when the elevator car 12 is at the bottom. When the accumulated water in the elevator pit 18 is squeezed by squeezing the squeezing buffer capsule 31, the accumulated water will flow through the gap between the squeezing buffer capsule 31 and the inner wall of the elevator shaft 11. Since the squeezed water has pressure, and the seal formed between the piston plate 21 and the bottom wall plate of the elevator car 12 and the inner wall of the elevator shaft 11 will prevent the accumulated water from flowing upward, so that the accumulated water will enter the water pipe 314 through the drainage hole 313, so that the accumulated water can be transported to the drainage system through the water pipe 314 for external discharge, thereby realizing the external discharge of the accumulated water in the elevator pit 18. At the same time, when the car 12 moves downward once, the accumulated water in the elevator pit 18 can be discharged once by squeezing, so that the accumulated water in the elevator pit 18 can be discharged without the help of drainage equipment. At the same time, the distance between the drainage hole 313 and the bottom of the elevator pit 18 is set to be smaller than the distance between the car 12 and the bottom of the elevator pit 18 when the car 12 is at the bottom, so as to ensure that when the car 12 is at the lowest position during normal use, it will not affect the drainage of the accumulated water in the elevator pit 18 through the drainage hole 313.
[0052] It should be noted that in order to allow the squeezing buffer capsule 31 to buffer the car 12 when it normally descends to the bottom floor, the height of the upper surface of the squeezing buffer capsule 31 is higher than the bottom of the car 12 when there is no water accumulation in the elevator pit 18, and the height of the upper surface of the squeezing buffer capsule 31 above the bottom of the car 12 is set to 50-80 mm, ensuring that the force required to squeeze the squeezing buffer capsule 31 is small when the car 12 is in normal use, and the water absorbing block 36 is in a compressed state under the action of the gravity of the squeezing buffer capsule 31. Only when there is water accumulation in the elevator pit 18 causing the squeezing buffer capsule 31 to move upward, the upward height needs to be squeezed back when the car 12 moves to the bottom floor, so that the car 12 can be docked at the bottom floor. Since the movement of the screw elevator is driven by the driving motor 15 to drive 12 up and down, when 12 moves downward to near the bottom floor, 12 has sufficient downward squeezing force. No matter what the load in the elevator is, 12 can drive the squeezing buffer bag 31 to move downward and compress the buffer device 39 when moving downward, so as to ensure that the water absorption block 36 is completely squeezed, so that the accumulated water in the water absorption block 36 and the elevator pit 18 can be discharged by squeezing.
[0053] When the elevator is in use, the car 12 will reciprocate in the elevator shaft 11. When the car 12 moves from the upper floor to the lower floor, the car 12 will drive the piston plate 21 to move. The piston plate 21 forms a seal with the bottom wall plate of the car 12 in the elevator shaft 11, so that when the piston plate 21 drives the car 12 to move downward, the air in the elevator shaft 11 can be compressed, so that the air in the elevator shaft 11 moves downward. When the car 12 moves to the bottom floor, the air in the elevator shaft 11 is compressed and transported to the bottom of the elevator pit 18. The air will dry the bottom of the elevator pit 18 through air flow to ensure that the elevator pit 18 is in a dry state; when there is water in the elevator pit 18, the water will be absorbed by the water absorbent block 36. When the car 12 moves to the bottom floor, the car 12 and the squeeze buffer capsule 3 When in contact with the elevator shaft 11, the extrusion buffer capsule 31 can be compressed, so that the extrusion buffer capsule 31 is deformed and drives the water absorbing block 36 to move downward, so that the extrusion buffer capsule 31 squeezes the water absorbing block 36. At the same time, the extrusion buffer capsule 31 compresses the buffer device 39, so that the extrusion buffer capsule 31 can completely squeeze the water absorbing block 36, so that the water in the water absorbing block 36 and the elevator pit 18 is squeezed and flows between the gap between the extrusion buffer capsule 31 and the inner side wall of the elevator shaft 11. When flowing, it will enter the water delivery pipe 314 through the drainage hole 313, and can be transported to the drainage system through the water delivery pipe 314, so as to realize the external discharge of the accumulated water in the elevator pit 18. At the same time, when the extrusion of the water absorbing block 36 cannot discharge water, the air squeezed in the elevator shaft 11 can dry the elevator pit 18 and the water absorbing block 36, so as to ensure that the elevator pit 18 is in a dry state.
