Technical Field

[0001] The utility model belongs to the technical field of elevator equipment, and in particular relates to an elevator water-avoiding and damage-preventing device. Background Art

[0002] Elevators are a common type of special transportation device used in buildings. Elevators run in a shaft specially set up for elevators. There are many devices for elevator operation in the elevator shaft, and some buildings have some small water outlets in the elevator shaft. When the elevator car itself is equipped with air conditioning, water will also be discharged. Water will accumulate in the pit of the elevator shaft after a long time. At the same time, buffers, elevator stop switches, shaft light switches, power sockets and lighting are installed in the pit. If the water in the pit accumulates to a certain amount, it will have a greater impact on the electrical equipment in the pit. If the electrical equipment is immersed in water for a long time, it will rust and corrode, and may even cause safety accidents.

[0003] In the prior art, there is an elevator water-proofing and damage-prevention device with patent announcement number CN213738098U. The above patent can use this device to quickly raise the elevator car to a preset safe height and enter a protection state when the elevator car roof is flooded, the car is flooded, or the shaft pit is flooded. However, in actual use, there are still the following deficiencies: From a practical point of view, the elevator water-proofing and damage-prevention device is only a solution for when water enters the elevator or the elevator shaft, but it does not solve the cause of the elevator flooding, and it only treats the symptoms but not the root cause.

[0004] Therefore, there is a need for an elevator water-proof and damage-preventing device to solve the problem that the elevator water-proof and damage-preventing device in the prior art only provides a solution when water enters the elevator or elevator shaft, but does not solve the cause of water entering the elevator, thus treating the symptoms but not the root cause. Utility Model Content

[0005] The purpose of the utility model is to provide an elevator water-proof and damage-preventing device to solve the problems raised in the above-mentioned background technology.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an elevator water-proof and damage-preventing device, comprising an elevator shaft, an elevator installed on one side of the elevator shaft, the lower end of the elevator is fixedly connected to an elevator floor, a groove is provided in the middle of the lower end of the elevator floor, and the lower end of the elevator floor is located at the upper end of the groove and is fixedly connected to a pressure device, a plurality of regular guide grooves 1 are provided on the inner surface of the lower end of the elevator shaft, and a plurality of regular guide grooves 1 are connected at one end through guide groove 2, one side of the guide groove 2 is connected to a water storage tank provided on one side of the bottom end of the elevator shaft, a connecting hole is provided on one side of the bottom end of the water storage tank, and a U-shaped pipe is fixedly connected inside the connecting hole.

[0007] It should be noted in the scheme that the pressure device includes a pressure sensor, the upper end of the pressure sensor is fixedly connected to the upper surface of a groove provided in the middle part of the lower end of the elevator floor, and the lower end of the pressure sensor is fixedly connected to a connecting plate, the four corners of the lower end of the connecting plate are fixedly connected to springs, and the lower ends of the springs are fixedly connected to foam plates.

[0008] It is further worth noting that the pressure sensor includes but is not limited to a processor that transmits information to the elevator cabinet and only measures the pressure when the elevator reaches the bottom floor and stops.

[0009] It should be further explained that, in some rules, the guide groove 1 uniformly presents a certain downward slope toward one end of the guide groove 2.

[0010] As a preferred embodiment, the second guide groove is located on one side of the water storage tank and is fixedly connected to a filter.

[0011] As a preferred embodiment, a slope is provided at the lower end of the water storage tank, and the angle of the slope becomes smaller and smaller towards the connecting hole.

[0012] As a preferred embodiment, one end of the U-shaped tube is fixedly connected to the inside of the lower end of the connecting hole, and the other end of the U-shaped tube is fixedly connected to the inside of another small water tank, and the two ends of the U-shaped tube are located on the same plane.

[0013] Compared with the prior art, the elevator water-proof and damage-preventing device provided by the utility model has at least the following beneficial effects:

[0014] (1) Through the pressure device fixedly connected to the lower end of the elevator floor, it is detected whether there is water accumulation at the lower end. That is, when the elevator descends to the lowest floor and stops, if there is no water accumulation at the lower end of the elevator shaft, the pressure value transmitted by the pressure sensor to the elevator cabinet will be within a normal pressure value range. If there is water accumulation at the lower end of the elevator shaft, the buoyancy of the water will give the foam board an upward force, so that the pressure transmitted from the pressure sensor to the elevator cabinet will not be within the safe range, thereby increasing the practicality of the elevator water-proof and damage-preventing device.

[0015] (2) Through the functions of the guide grooves 1 and 2, the accumulated water is concentrated in the water storage tank, and then through a connecting hole provided at one end of the water storage tank, a U-shaped tube is provided inside the connecting hole, and the other end of the U-shaped tube is fixed inside a small water tank outside, and the two ends of the U-shaped tube are located on the same plane, that is, due to the characteristic that the pressure at both ends of the connecting tube is the same and they are located on the same plane, the accumulated water in the water storage tank will be transferred to the inside of the small water tank outside, and then the water in the small water tank outside can be taken out to ensure the dryness of the elevator shaft.

[0016] (3) The solid impurities in the accumulated water are filtered and screened by the filter, which prevents the solid impurities in the elevator shaft from being discharged into the water storage tank through the diversion grooves 1 and 2, resulting in excessive accumulation of impurities in the water storage tank and the U-shaped tube, thereby ensuring the cleanliness of the water storage tank and the U-shaped tube. Therefore, the staff only needs to regularly remove the solid impurities on the filter to ensure the long-term use effect of the filter. BRIEF DESCRIPTION OF THE DRAWINGS

[0021] The present invention will be further described below in conjunction with the embodiments.

[0022] See also Figure 1-3 The utility model provides an elevator water-proof and damage-preventing device, comprising: an elevator shaft 1, an elevator is installed on one side of the elevator shaft 1, an elevator bottom plate 2 is fixedly connected to the lower end of the elevator, a groove 303 is provided in the middle of the lower end of the elevator bottom plate 2, and the lower end of the elevator bottom plate 2 is located at the upper end of the groove 303 and is fixedly connected to a pressure device 3, a plurality of regular guide grooves 1 5 are provided on the inner surface of the lower end of the elevator shaft 1, and one end of the plurality of regular guide grooves 1 5 is connected through the guide groove 2 6, and one side of the guide groove 2 6 is connected through the water storage tank 7 provided on one side of the bottom end of the elevator shaft 1, and a connecting hole 9 is provided on one side of the bottom end of the water storage tank 7, and a U-shaped pipe 10 is fixedly connected inside the connecting hole 9.

[0023] Further Figure 2 As shown, it is worth specifically explaining that the pressure device 3 includes a pressure sensor 301, the upper end of the pressure sensor 301 is fixedly connected to the upper surface of a groove 303 provided in the middle of the lower end of the elevator floor 2, and the lower end of the pressure sensor 301 is fixedly connected to a connecting plate 302, the four corners of the lower end of the connecting plate 302 are fixedly connected to springs 304, and the lower ends of the springs 304 are fixedly connected to foam plates 305. The pressure value transmitted to the elevator cabinet by the pressure sensor 301 can determine whether there is water accumulation at the lower end of the elevator shaft 1.

[0024] Further Figure 2 As shown, it is worth explaining in detail that the pressure sensor 301 includes but is not limited to transmitting information to the processor of the elevator cabinet and only measuring the pressure when the elevator reaches the bottom floor and stops. Through the pressure sensor 301, the elevator cabinet can accurately understand and control the internal situation of the elevator shaft 1.

[0025] This solution has the following working process: when the elevator descends to the lowest floor and stops, if there is no water accumulation at the lower end of the elevator shaft 1, the pressure value transmitted to the elevator cabinet by the pressure sensor 301 will be within a normal pressure value range. If there is water accumulation at the lower end of the elevator shaft 1, the buoyancy of the water will give the foam board 305 an upward force, so that the pressure value transmitted from the pressure sensor 301 to the elevator cabinet will not be within the safe range, and the water flow is concentrated into the water storage tank 7 through the guide groove 1 5 and the guide groove 2 6, and then through the connection hole 9 provided at one end of the water storage tank 7, a U-shaped tube 10 is provided inside the connection hole 9, and the other end of the U-shaped tube 10 is fixed in a small water tank outside The two ends of the U-shaped tube 10 are located on the same plane, that is, through the characteristics of the same pressure at both ends of the connecting tube, the accumulated water in the water storage tank 7 will be transferred to the inside of the external small water tank, and then the water in the external small water tank can be taken out to ensure the dryness of the elevator shaft 1, and the solid impurities in the accumulated water are filtered and screened by the filter 4, avoiding the solid impurities in the elevator shaft 1 from being discharged into the water storage tank 7 through the guide groove 1 5 and the guide groove 2 6, resulting in excessive accumulation of impurities in the water storage tank 7 and the U-shaped tube 10, thereby ensuring the cleanliness of the water storage tank 7 and the U-shaped tube 10, so the staff only needs to remove the solid impurities on the filter 4 regularly.

[0026] According to the above working process, it can be known that the pressure value transmitted to the elevator cabinet by the pressure sensor 301 can be used to determine whether there is water accumulation at the lower end of the elevator shaft 1. Through the pressure sensor 301, the elevator cabinet can accurately understand and control the internal situation of the elevator shaft 1.

[0027] Further Figure 1 As shown, it is worth explaining in detail that a plurality of regular guide grooves 1 5 are uniformly inclined downward toward one end of the guide groove 2 6 , and the shape of the guide groove 1 5 makes it easier for the accumulated water to gather inside the water storage tank 7 .

[0028] Further Figure 3 As shown, it is worth explaining in detail that the guide groove 2 6 is located on one side of the water tank 7 and is fixedly connected to the filter screen 4. The solid impurities in the accumulated water are filtered and screened through the filter screen 4, thereby preventing the solid impurities in the elevator shaft 1 from being discharged into the water tank 7 through the guide groove 1 5 and the guide groove 2 6, resulting in excessive accumulation of impurities in the water tank 7 and the U-shaped tube 10, thereby ensuring the cleanliness of the water tank 7 and the U-shaped tube 10. Therefore, the staff only needs to clean the solid impurities on the filter screen 4 regularly.

[0029] Further Figure 1 As shown, it is worth specifically explaining that a slope 8 is provided at the lower end of the water storage tank 7, and the angle of the slope 8 becomes smaller and smaller toward the side of the connecting hole 9. By providing the slope 8 at the lower end of the water storage tank 7, the accumulated water in the water storage tank 7 is guided to gather toward the side of the connecting hole 9, so as to be easily discharged through the U-shaped tube 10.

[0030] Further Figure 1 As shown, it is worth explaining in detail that one end of the U-shaped tube 10 is fixedly connected to the inside of the lower end of the connecting hole 9, and the other end of the U-shaped tube 10 is fixedly connected to the inside of another small water tank, and the two ends of the U-shaped tube 10 are located on the same plane. Due to the characteristic that the pressures at both ends of the connecting tube are the same and they are located on the same plane, the accumulated water in the water storage tank 7 will be transferred to the inside of the external small water tank, and then the water in the external small water tank can be taken out to ensure the dryness of the elevator shaft 1.

[0031] In summary: when the elevator descends to the bottom and stops, if there is no water accumulation at the lower end of the elevator shaft 1, the pressure value transmitted by the pressure sensor 301 to the elevator cabinet will be within a normal pressure value range. If there is water accumulation at the lower end of the elevator shaft 1, the buoyancy of the water will give the foam plate 305 an upward force, so that the pressure value transmitted from the pressure sensor 301 to the elevator cabinet will not be within the safe range, and the water flow is concentrated into the water storage tank 7 through the guide groove 1 5 and the guide groove 2 6, and then connected through the connection hole 9 provided at one end of the water storage tank 7. A U-shaped tube 10 is provided inside the hole 9, and the other end of the U-shaped tube 10 is fixed inside a small water tank outside, and the two ends of the U-shaped tube 10 are located on the same plane, that is, through the characteristics that the pressure at both ends of the connecting pipe is the same and they are located on the same plane, the accumulated water in the water storage tank 7 will be transferred to the inside of the external small water tank, and then the water in the external small water tank can be taken out to ensure the dryness of the elevator shaft 1, and the solid impurities in the accumulated water are filtered and screened by the filter screen 4, so as to avoid the solid impurities in the elevator shaft 1 from being discharged into the water storage tank through the guide groove 1 5 and the guide groove 2 6. The situation that too many impurities are accumulated in the water storage tank 7 and the U-shaped tube 10 is ensured, so the cleanliness of the water storage tank 7 and the U-shaped tube 10 is guaranteed. Therefore, the staff only needs to regularly remove the solid impurities on the filter 4. Through the shape setting of the guide groove 1 5, the accumulated water is more likely to accumulate in the water storage tank 7, and the solid impurities in the accumulated water are filtered and screened by the filter 4, which avoids the solid impurities in the elevator shaft 1 from being discharged into the water storage tank 7 through the guide groove 1 5 and the guide groove 2 6, resulting in the accumulation of impurities in the water storage tank 7 and the U-shaped tube 10. The situation of collecting too many impurities ensures the cleanliness of the water tank 7 and the U-shaped tube 10. Therefore, the staff only needs to clean the solid impurities on the filter 4 regularly. The slope 8 is provided at the lower end of the water tank 7 to guide the accumulated water in the water tank 7 to gather on the side of the connecting hole 9, which is convenient for discharge through the U-shaped tube 10. The pressure at both ends of the connecting tube is the same and they are located in the same plane. The accumulated water in the water tank 7 will be transferred to the inside of the external small water tank, and then the water in the external small water tank can be taken out to ensure the dryness of the elevator shaft 1.
