DETAILED DESCRIPTION
[0031] The following will be combined with the attached Figure 1 To Attachment Figure 7 The technical solutions in the embodiments of the utility model are clearly and completely described. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.
[0032] Elevators provide great convenience for daily travel of high-rise residents. Elevators usually have a shaft with a car that can move up and down for people to ride. The top of the shaft is sealed, leaving only some vents on the side walls of the shaft to the outside. However, this type of ventilation is not smooth enough, resulting in a very high temperature inside the shaft. Especially in some places in the south with higher temperatures, the temperature inside the shaft can even reach 60 degrees, making it inconvenient for people to travel and affecting the service life of the elevator.
[0033] In this regard, the inventor provides an elevator, the purpose of which is to solve the problem of excessively high temperature inside the elevator shaft.
[0034] like Figure 1 and Figure 2 As shown, an elevator comprises a shaft 1 and a top cover panel 2, wherein the top cover panel 2 is arranged at the top of the shaft 1 to close the opening of the shaft 1. There are columns 12 around the outside of the shaft 1, and the columns 12 are arranged at four right angles outside the shaft 1. The top of the column 12 is flush with the top of the shaft 1, and the column 12 is assembled and connected with the top cover panel 2 through a ventilation structure 3; the ventilation structure 3 comprises a top cover portion 34, and the top cover portion 34 is bent and connected with a surrounding portion 31 around it, and the top cover portion 34 and the surrounding portion 31 are keel frames; the keel frame comprises a plurality of segment components; the plurality of segment components are assembled into the keel frame with various shapes according to actual needs. In actual use, the keel frame can have a variety of shapes, such as rectangle, square, etc., of course, it is not limited to these shapes, such as other circular and irregular shapes, which are all within the protection scope of this technical solution.
[0035] The top cover 34 is a hollow frame structure, and the cross section of the top cover 34 is rectangular or square, etc. The top cover 34 is assembled on the top of the column 12 by welding or locking, such as by screwing, and then sealed with sealant to prevent water seepage. And the outline of the ventilation structure 3 should be at least not less than the outline formed by the connecting line of the four right-angled columns 12, so that after the through structure 3 is assembled on the top of the column 12, the ventilation structure 3 can place the column 12 on the inner side of the top cover 34, so as to facilitate the formation of a gap between the inner side wall of the top cover 34 and the outer side wall of the column 12, and the gap is the inner side of the ventilation structure 3 and the outer side wall of the well 1 to form a ventilation channel 33, so as to guide the airflow inside the well 1 from the ventilation channel 33 to the outside. Specifically, the ventilation structure 3 has a surrounding portion 31 at its periphery; the surrounding portion 31 surrounds the peripheral area near the opening of the shaft 1 and forms a ventilation passage 33 with the outer wall of the shaft 1 .
[0036] One end of the ventilation duct 33 is connected to the interior of the shaft 1, and the other end of the ventilation duct 33 is connected to the outside. It can be understood that the hot air inside the shaft 1 can flow to the outside along the ventilation duct 33, thereby avoiding poor ventilation inside the shaft 1, heat accumulation, and excessive temperature.
[0037] like Figure 3 As shown, since the surrounding portion 31 is located in the peripheral area near the opening of the shaft 1, and the surrounding portion 31 has a hollow area 311, the surrounding portion 31 is designed to have the hollow area 311 for the purpose of saving materials. Since elevators are usually at a relatively high height, it is inconvenient to carry heavier materials to a high place. Therefore, designing the surrounding portion 31 to have a hollow area 311 is beneficial to saving materials and facilitating transportation.
[0038] However, this makes it easy for rainwater to intrude into the hollow area 311 laterally and enter the interior of the well 1 on rainy days, causing mechanical equipment in the well 1 to malfunction.
[0039] In order to prevent rainwater from laterally invading the well 1, Figure 4 As shown, the ventilation structure 3 further has a waterproof component 32 ; the waterproof component 32 is used to cover the hollow area 311 .
[0040] It should be understood that in actual use, when the elevator moves up and down inside the shaft 1, a certain airflow pressure difference will be generated between the inside of the shaft 1 and the outside. When the air pressure inside the shaft 1 is lower than the outside air pressure, if it rains at this time, the ventilation duct 33 formed by the ventilation structure 3 and the shaft 1 will easily absorb rainwater from the outside into the shaft 1, thereby affecting the service life of the elevator. For this purpose, the hollow area 311 needs to be shielded. In other usage scenarios, the surrounding part can also be produced into a closed integrated structure. However, it is preferred that the surrounding part 31 in this embodiment is a hollow structure, which can save materials and prevent rainwater from invading.
[0041] Specific as Figure 4 As shown, the waterproof component 32 includes a first protrusion 321 and a second protrusion 322; the first protrusion 321 and the second protrusion 322 are connected by a connecting portion 323; the first protrusion 321 is welded to the top cover portion 34, and the top cover panel 2 is sealed and connected to the first protrusion 321.
[0042] Specific as Figure 4 As shown, the waterproof member 32 starts from the edge of the top 312 of the surrounding portion 31 and extends to cover the surface 313 of the surrounding portion 31 and ends at the back surface 314 of the surrounding portion 31 .
[0043] It should be noted that the top 312 of the enclosing portion 31 is also covered with the top cover panel 2, the top cover panel 2 is welded to the edge of the top cover portion 34, and the first protrusion 321 of the waterproof member 32 starts from the top 312 of the enclosing portion 31. It can be understood that the edge of the top cover panel 2, the edge of the top cover portion 34 and the first protrusion 321 are sealed and welded together. This design method allows the first protrusion 321 to be connected to the edge of the top cover portion 34 to solve the problem that the existing screw connection and fixation, rainwater seeps into the connection of the screws, and the connection will be rusted and damaged over time.
[0044] Furthermore, the waterproof member 32 covers the entire hollow area 311, so that rainwater will not laterally intrude into the interior of the well 1 from the hollow area 311. In this embodiment, the waterproof member 32 extends from the edge of the top 312 of the surrounding portion 31 to cover the surface 313 of the surrounding portion 31 and ends at the back 314 of the surrounding portion 31. The exposed portion of the entire surrounding portion 31 is wrapped, which can better prevent the lateral intrusion of rainwater.
[0045] Further, Figure 4As shown, the waterproof member 32 is closely connected to the surrounding portion 31. Thus, the connection between the waterproof member 32 and the surrounding portion 31 is more tightly sealed, and the lateral intrusion of rainwater can be more effectively prevented.
[0046] In some other embodiments, the waterproof member 32 has various shapes, such as Figure 5 The waterproof component 32 shown in the present embodiment has a longitudinal section that is shaped like a "C", and the back of the waterproof component 32 is close to the hollow area 311 of the surrounding portion 31 to cover the hollow area 311.
[0047] In some other embodiments, the waterproof member 32 can also be Figure 6 As shown, in the waterproof component 32, the connection between the second protrusion 322 and the connection portion 323 has an angle 324; the angle of the angle 324 is between 90° and 150°.
[0048] It should be understood that when the angle between the second protrusion 322 and the connection portion 323 is an obtuse angle, i.e., greater than 90°, rainwater entering there can flow outward along the inclination angle of the second protrusion 322, thereby preventing rainwater from accumulating at the connection between the second protrusion 322 and the connection portion 323. The service life of the waterproof member 32 can be effectively extended.
[0049] Furthermore, Figure 7 As shown, the waterproof component 32 can also be presented in a "Z"-like shape. The top of the "Z"-shaped waterproof component 32 has two extensions B, and the two extensions B extend in opposite directions. The two extensions B are connected by a connecting portion 323, and the connecting portions 323 are bent and connected respectively. It can be understood that the two extensions B are respectively bent and connected to the connecting portion 323 so that the shape of the waterproof component 32 is more in line with the shape of the surrounding portion 31. The connecting portion 323 covers the hollow area 311 of the surrounding portion 31, and the upper extension B is welded to the top cover portion 34 and the top cover panel 2. However, the extension B of the waterproof component 32 close to the bottom is used to receive rainwater, thereby effectively preventing rainwater from invading the inside of the well 1.
[0050] Furthermore, Figure 2As shown, the shaft 1 has a plurality of buckle strips 11 on the outer circumference; the surface of the buckle strips 11 is at least 30 mm away from the inner surface of the surrounding portion 31. The purpose of such design is to allow the outer contour of the top cover 34 to accommodate the shaft 1 inside, so that the inner surface of the edge of the top cover 34 and the outer surface of the edge of the shaft 2 have a sufficient gap, that is, to form a sufficiently large ventilation duct 33, so that the airflow inside the shaft 1 can effectively flow from the ventilation duct 33 to the outside, and further effectively prevent rainwater from laterally invading the shaft 1.
[0051] To sum up, an elevator has a ventilation structure 3 at the top of the shaft 1, which can effectively solve the problem of poor ventilation inside the shaft 1. While solving the problem of poor ventilation, it can also effectively prevent rainwater from invading the inside of the shaft 1 through the ventilation duct 33, that is, an elevator according to the present technical solution solves the problem of poor ventilation and the problem of rainwater intrusion.
