[0002] "Installing an elevator" refers to the construction of a new elevator system, either externally or internally, in an existing building or residence. This type of project is commonly found in multi-story residential buildings, older communities, public facilities, and other places where elevators are not available or where existing elevators are insufficient. The purpose of installing an elevator is to facilitate travel for residents and users, particularly to address vertical transportation issues for the elderly, disabled, and sick, as well as for transporting large items.
[0003] With the continuous advancement of urban renewal and renovation, installing elevators in older residential buildings has become an important measure to improve residents' quality of life. However, after the installation of elevators, ventilation and heat dissipation within the elevator shaft have become increasingly prominent. Especially in hot summer weather, the high temperature and stuffiness within the elevator shaft not only affects the normal operation of the elevator equipment but also reduces the comfort of passengers.
[0004] Therefore, there is an urgent need for a ventilation and heat dissipation structure for installing an elevator to solve the above problems. Utility Model Content
[0005] In response to the existing deficiencies, the present invention provides a ventilation and heat dissipation structure for installing an elevator in an existing building. The ventilation and heat dissipation structure can effectively solve the problem of rainwater entering the elevator shaft in windy and rainy weather, while promoting the flow exchange of air inside and outside the shaft, reducing the temperature inside the shaft, and improving the operating stability of the elevator equipment and the comfort of the passengers.
[0006] In order to achieve the above purpose, the technical solution adopted by the utility model is:
[0007] A ventilation and heat dissipation structure for installing an elevator in an existing building, comprising an air duct arranged outside the elevator shaft, the air duct being connected to the interior of the elevator shaft and protruding from the surface of the elevator shaft, a ventilation and heat dissipation mechanism being provided on both sides of the air duct for ventilation and heat dissipation, and two sets of symmetrical top vents being opened at the top of the air duct;
[0008] The ventilation and heat dissipation mechanism includes a guide box, a diversion pipe, a ventilation pipe, a circulation fan and side vents. The side vents are opened on the outside of the air duct, and the side vents are equipped with a circulation fan. The outside of the side vents is connected to a ventilation pipe, and the outer end of the ventilation pipe is fixedly connected to a guide box with a cross-shaped structure.

[0009] Furthermore, a layer of protective net is fixedly provided inside the top vent.
[0010] Furthermore, a ceiling with an arc-shaped structure that is high in the middle and low at both ends is provided on the top of the air duct, and the ceiling is fixedly connected to the top of the air duct through multiple groups of fixed support rods.
[0011] Furthermore, a mesh cover is installed on the outer end surface of the diversion pipe.

[0013] Furthermore, the ventilation and heat dissipation mechanism is arranged between adjacent floors in the elevator shaft.
[0014] Compared with the prior art, the present invention has the following beneficial effects:
[0015] 1. The utility model can ventilate and dissipate heat inside the elevator shaft, which can effectively solve the problem of rainwater entering the elevator shaft in windy and rainy weather.

[0025] The following will be combined with the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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 making creative efforts are within the scope of protection of the present invention.
[0026] Example:
[0027] like Figures 1 to 6 As shown, a ventilation and heat dissipation structure for installing an elevator in an existing building includes an air duct 3 arranged on the outside of the elevator shaft 2. The air duct 3 is connected to the interior of the elevator shaft 2 and the outer side protrudes from the surface of the elevator shaft 2. The air duct 3 serves as a channel for air flow, which can introduce fresh air from the outside into the elevator shaft 2, while guiding the flow and exhaust of hot air in the shaft. Ventilation and heat dissipation mechanisms 4 for ventilation and heat dissipation are provided on both sides of the air duct 3. Two sets of symmetrical top vents 5 are opened at the top of the air duct 3. The top vents 5 are used to exhaust hot air in the shaft and help form air convection, thereby enhancing the ventilation effect.
[0028] The ventilation and heat dissipation mechanism 4 includes a guide box 41, a diverter pipe 42, a ventilation pipe 44, a circulation fan 45 and a side vent 46. The side vent 46 is opened on the outside of the air duct 3. The side vent 46 serves as an air inlet and can inhale air according to the working state of the circulation fan 45. The side vent 46 is equipped with a circulation fan 45 inside. The circulation fan 45 provides power for air flow, drives the air to circulate in the air duct 3, and accelerates the ventilation and heat dissipation process. The outside of the side vent 46 is connected to the ventilation pipe 44, which serves as an air transmission pipe. The air is guided into the air duct 3, and the outer end of the ventilation pipe 44 is fixedly connected to a cross-shaped guide box 41, and the four sides of the guide box 41 are connected to a diversion pipe 42 connected thereto. The diversion pipe 42 and the guide box 41 can simultaneously inhale air from four directions and guide the flow of air, thereby improving the ventilation effect. This design solves the problem that the ventilation and heat dissipation effect in the existing elevator shaft is not good enough, especially in hot summer weather, the elevator shaft 2 is hot and stuffy, which not only affects the normal operation of the elevator equipment, but also reduces the comfort of the passengers.
[0029] This ventilation and heat dissipation structure can ventilate and dissipate heat inside the elevator shaft 2, which can effectively solve the problem of rainwater entering the elevator shaft 2 in windy and rainy weather. At the same time, it promotes the flow exchange of air inside and outside the shaft, reduces the temperature inside the shaft, and improves the operating stability of the elevator equipment and the comfort of the passengers.
[0030] In this embodiment, a protective net 51 is fixed inside the top vent 5. The protective net 51 can effectively prevent flying birds, small animals, fallen leaves, debris, etc. from entering the elevator shaft 2, avoiding damage to the elevator equipment or operational failures, and also reducing the frequency and difficulty of maintenance.
[0031] In this embodiment, a ceiling 1 with a high middle and low two ends and an arc-shaped structure is provided on the top of the air duct 3. The ceiling 1 can effectively block rainwater and prevent it from directly entering the elevator shaft 2, thereby protecting the elevator equipment and maintaining the normal operation of the ventilation system. At the same time, the arc-shaped structure helps the natural drainage of rainwater and reduces the occurrence of water accumulation. In addition, the arc-shaped design with a high middle and low two ends helps to guide the flow of air, so that the air can be discharged from the air duct 3 more smoothly, accelerating the discharge of hot air in the elevator shaft 2 and improving the ventilation and heat dissipation efficiency. The ceiling 1 is fixedly connected to the top of the air duct 3 through multiple groups of fixed support rods 11.
[0032] In this embodiment, a mesh cover 43 is installed on the outer end surface of the diversion pipe 42. The mesh cover 43 can effectively prevent insects, small animals, fallen leaves and other debris from entering the diversion pipe 42, thereby avoiding blockage of the pipe or affecting the ventilation and heat dissipation effect, helping to maintain the smooth flow of the ventilation system and extend its service life.
[0033] In this embodiment, the ventilation pipe 44 is configured as an inclined structure, and the end thereof connected to the air duct 3 is higher than the end connected to the guide box 41. The inclined structure of the ventilation pipe 44 can effectively prevent the entry of external rain and snow, and can ensure that moisture will not accumulate in the pipe, but will flow down the pipe wall and be discharged from the system, reducing the impact on the ventilation system.
[0034] In this embodiment, the ventilation and heat dissipation mechanism 4 is arranged between adjacent floors on the elevator shaft 2. This design can ensure that the ventilation and heat dissipation mechanism 4 always has a good ventilation effect. When the elevator reaches a floor and stops, it will not affect the normal operation of the ventilation and heat dissipation mechanism 4 and hinder the flow of air in the elevator shaft 2.
[0035] The working principle of the ventilation and heat dissipation structure of an existing building equipped with an elevator is as follows: first, the ventilation and heat dissipation mechanism 4 is installed between adjacent floors on the elevator shaft 2, and the ventilation and heat dissipation mechanism 4 is connected to the inside of the air duct 3. When the circulating fan 45 is started, a negative pressure is generated on one side of the inside of the air duct 3, which drives the air to be sucked in from the mouth of the diversion pipe 42. The air passes through the guide box 41 and enters the ventilation pipe 44, and then flows into the air duct 3 through the ventilation pipe 44. The air flows along the air duct 3 and flows to the inside of the elevator shaft 2. It flows inside the elevator shaft 2 and flows to the top vent 5 for discharge. At the same time, fresh air from the outside continuously enters the shaft through the side vents 46, forming continuous air convection. This design not only improves the ventilation and heat dissipation effect, but also ensures the air quality in the elevator shaft 2.
[0036] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not limitations on the implementation methods of the present invention. For ordinary technicians in the relevant field, other different forms of changes or modifications can be made based on the above description. It is impossible to list all the implementation methods here. All obvious changes or modifications derived from the technical solution of the present invention are still within the scope of protection of the present invention.
