Description

Technical Field

[0001] The utility model relates to the technical field of foundation pits, and in particular to an elevator foundation pit with a water accumulation prevention function. Background Art

[0002] The elevator foundation pit refers to a deep pit dug underground for the installation of an elevator. It is generally square or rectangular in shape. It is located at the bottom or basement of a building and is part of the elevator shaft. The depth and size of the elevator foundation pit depend on the model and design requirements of the elevator. It needs to be comprehensively considered in the early stages of design in combination with geological and soil conditions as well as the surrounding environment of the building.

[0003] For some existing elevator pits, when draining water through the water pump inside, larger substances in the accumulated water enter the pipes, which can easily cause blockage in the pipes, slowing down the discharge efficiency of the accumulated water. In addition, after the accumulated water is discharged from such elevator pits, there will still be moisture on the inner wall surface, which takes a long time to evaporate naturally. At this time, the elevator pit is in a humid state, which can easily cause damage to electronic devices.

[0004] Therefore, those skilled in the art provide an elevator foundation pit with a water-proof function to solve the problems raised in the above-mentioned background technology. Utility Model Content

[0005] In view of the defects in the prior art, the utility model provides an elevator foundation pit with a water-proof function to improve the efficiency of discharging accumulated water.

[0006] An elevator foundation pit with a water accumulation prevention function, comprising an elevator foundation pit body, a filtering mechanism, a first water level sensor and a second water level sensor, a protective shell is embedded in the middle of the inner bottom surface of the elevator foundation pit body, a water pump is fixedly arranged on the inner wall of the protective shell, a plurality of water inlet holes are opened on the inner bottom surface of the elevator foundation pit body, and a water outlet hole is opened in the middle of the front side of the upper end face of the elevator foundation pit body;

[0007] The filtering mechanism comprises a first cover plate and two second cover plates, and filter screens are fixedly arranged on the inner walls around the two second cover plates;

[0009] Preferably, the filtering mechanism is fixedly arranged on the inner bottom surface of the elevator foundation pit body by bolts, and the two second cover plates are fixedly connected to the first cover plate by connecting blocks.

[0010] Preferably, the water inlet of the water pump is fixedly connected to the multiple water inlet holes through a pipeline, and the water outlet of the water pump is fixedly connected to the water outlet holes through a pipeline.

[0011] Preferably, the first water level sensor is embedded in the middle position of the inner wall on one side of the elevator foundation pit body, and the second water level sensor is embedded in the middle position of the inner bottom surface on one side of the elevator foundation pit body.

[0012] Preferably, the two T-shaped blocks are respectively slidably arranged on the upper sides of the inner walls on both sides of the elevator foundation pit body, and the four strip plates are respectively fixedly connected to the two T-shaped blocks in pairs.

[0013] Preferably, a waterproof layer is fixedly provided on the outer end surface of the elevator foundation pit body.

[0015] The beneficial effects of the utility model are embodied in:

[0016] 1. When the accumulated water inside the elevator pit body exceeds the first water level sensor, the water pump is controlled to start operating, and the accumulated water passes through the grooves opened around the first cover plate, and then passes through the filter screen on the surface around the second cover plate to enter the water inlet hole, and finally through the water outlet hole, the accumulated water is discharged from the inside of the elevator pit body. The two second cover plates are protected by the first cover plate. When operating inside the elevator pit body, damage to the filter screen inside the two second cover plates is prevented. By arranging the second cover plate and the filter screen at the upper end of the water inlet hole, when extracting the accumulated water, larger substances will not enter the pipe, avoiding pipe blockage and further improving the drainage efficiency.

[0017] 2. After the drainage is completed, the electric telescopic rod and the fan are opened. The electric telescopic rod drives the strip plate integrated with it to slide forward through the T-shaped block, so that the two strip plates no longer block the opening of the U-shaped groove. At this time, the fan draws air from the opening at the upper end of the U-shaped groove, and then blows the wind from the opening at the lower end of the U-shaped groove to the inside of the elevator foundation pit body. After ventilation for a period of time, the fan is turned off, and the electric telescopic rod drives the strip plate back to its original position. By setting up the fan, the air circulation inside the elevator foundation pit body becomes faster, which accelerates the evaporation of moisture on the inner wall surface of the elevator foundation pit body and avoids damage to electronic devices.

DETAILED DESCRIPTION

[0026] The following embodiments of the technical solution of the utility model are described in detail in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the utility model, and are therefore only used as examples, and cannot be used to limit the protection scope of the utility model.

[0027] It should be noted that, unless otherwise specified, the technical terms or scientific terms used in this application should have the common meanings understood by technicians in the field to which the utility model belongs.

[0028] An elevator foundation pit with a water accumulation prevention function comprises an elevator foundation pit body 1, a filtering mechanism 2, a first water level sensor 14 and a second water level sensor 15, a protective shell 3 is embedded in the middle position of the inner bottom surface of the elevator foundation pit body 1, a water pump 4 is fixedly arranged on the inner wall of the protective shell 3, a plurality of water inlet holes 5 are provided on the inner bottom surface of the elevator foundation pit body 1, a water outlet hole 6 is provided in the middle position of the front side of the upper end surface of the elevator foundation pit body 1, the filtering mechanism 2 comprises a first cover plate 201 and two second cover plates 202, filter screens 203 are fixedly arranged on the inner walls around the two second cover plates 202, the first water level sensor 14 is embedded in the middle position of the inner wall on one side of the elevator foundation pit body 1, and the second water level sensor 15 is embedded in the middle position of one side of the inner bottom surface of the elevator foundation pit body 1.

[0029] When the accumulated water inside the elevator foundation pit body 1 exceeds the first water level sensor 14, the water pump 4 starts to operate, and the accumulated water inside the elevator foundation pit body 1 passes through the grooves opened around the first cover plate 201 and enters the interior of the first cover plate 201, and then the accumulated water passes through the filter screen 203 on the surface around the second cover plate 202 and enters the multiple water inlet holes 5, and finally the accumulated water is discharged from the interior of the elevator foundation pit body 1 through the water outlet hole 6. When the second water level sensor 15 cannot detect the accumulated water, the water pump 4 stops running, and the two second cover plates 202 are blocked by the first cover plate 201 to protect the two second cover plates 202. When operating inside the elevator foundation pit body 1, the filter screen 203 arranged on the surface of the two second cover plates 202 will not be damaged. By arranging the second cover plate 202 and the filter screen 203 at the upper end of the water inlet hole 5, when the accumulated water is extracted, larger substances will not enter the pipeline, thereby avoiding pipeline blockage and further improving the drainage efficiency.

[0030] U-shaped grooves 8 are provided on the upper sides of the inner walls on both sides of the elevator foundation pit body 1, and two fans 9 are fixedly arranged on the opposite side of the top surfaces of the two U-shaped grooves 8. Strip plates 10 are slidably arranged on the upper sides and the opposite sides of the lower inner walls of the two U-shaped grooves 8, and water-blocking pads 11 are fixedly arranged on the upper end surfaces and lower end surfaces of the four strip plates 10. Electric telescopic rods 13 are fixedly arranged on the front sides of the upper sides of the inner walls on both sides of the elevator foundation pit body 1, and T-shaped blocks 12 are fixedly arranged on the output ends of the two electric telescopic rods 13. The two T-shaped blocks 12 are respectively slidably arranged on the upper sides of the inner walls on both sides of the elevator foundation pit body 1, and the four strip plates 10 are fixedly connected to the two T-shaped blocks 12 in pairs.

[0031] When the water pump 4 stops running, the electric telescopic rod 13 and the fan 9 are opened, and the electric telescopic rod 13 drives the T-shaped block 12 to slide forward, and the T-shaped block 12 drives the two strip plates 10 connected thereto to slide forward. When the electric telescopic rod 13 is retracted for a distance, it stops running. At this time, the two strip plates 10 no longer block the two open ends of the U-shaped groove 8, and the fan 9 sucks wind into the U-shaped groove 8 from the opening at the upper end of the U-shaped groove 8, and then blows the wind from the opening at the lower end of the U-shaped groove 8 to the inside of the elevator foundation pit body 1. After the fan 9 has worked for a period of time, the fan 9 stops running, and the electric telescopic rod 13 drives the T-shaped block 12 to return to its original position. At this time, the two strip plates 10 block the opening of the U-shaped groove 8 again to prevent other substances from entering the U-shaped groove 8. By setting the fan 9, the air circulation inside the elevator foundation pit body 1 becomes faster, and the evaporation of moisture on the inner wall surface of the elevator foundation pit body 1 is accelerated.

[0032] The filter mechanism 2 is fixedly arranged on the inner bottom surface of the elevator foundation pit body 1 by bolts 205, and the two second cover plates 202 are fixedly connected to the first cover plate 201 by connecting blocks 204. The lower side of the outer end surface of the first cover plate 201 penetrates and slides on the inner bottom surface of the elevator foundation pit body 1, and the lower sides of the outer end surfaces of the two second cover plates 202 penetrate and slide on both sides of the inner bottom surface of the elevator foundation pit body 1. When cleaning the filter screen 203, the bolts 205 are turned to release the fixation of the elevator foundation pit body 1 on the first cover plate 201, and then the first cover plate 201 is lifted up. The first cover plate 201 drives the two second cover plates 202 to move upward together through the connecting blocks 204. A waterproof layer 7 is fixedly arranged on the outer end surface of the elevator foundation pit body 1. By applying the waterproof layer 7 on the surface of the elevator foundation pit body 1, when the surface of the elevator foundation pit body 1 contacts the ground, the penetration of moisture is reduced.

[0033] Working principle: when the accumulated water exceeds the first water level sensor 14, the water pump 4 starts to run, and the accumulated water inside the elevator pit body 1 enters the first cover plate 201 through the grooves opened around the first cover plate 201, and then the accumulated water enters the water inlet hole 5 through the filter screen 203 on the surface around the second cover plate 202, and finally is discharged from the interior of the elevator pit body 1 from the water outlet hole 6. When the second water level sensor 15 does not detect the accumulated water, the water pump 4 stops running, the electric telescopic rod 13 and the fan 9 are turned on, and the electric telescopic rod 13 drives the two strip plates 10 to slide forward through the T-shaped block 12. After sliding for a distance, the electric telescopic rod 13 stops working. At this time, the fan 9 sucks the wind into the inside of the U-shaped groove 8, and then blows it to the inside of the elevator pit body 1 through the opening at the lower end of the U-shaped groove 8. After the fan 9 has worked for a period of time, the fan 9 stops running, the electric telescopic rod 13 drives the T-shaped block 12 back to its original position, and the two strip plates 10 block the opening of the U-shaped groove 8 again.
