[0002] With the concept of energy conservation and emission reduction gaining popularity, energy-saving technologies have been widely applied in various fields. In the field of passenger elevators, especially small-tonnage passenger elevators, in order to improve energy efficiency and reduce energy consumption, more and more elevator designs are incorporating solar energy utilization technology. One common method is to install photovoltaic panels on the outside of the elevator shaft, which convert solar energy into electrical energy through the photovoltaic effect to provide auxiliary power for the elevator system, thereby achieving the goal of energy conservation.

[0003] However, after photovoltaic panels are installed outdoors, they are exposed to natural conditions for a long time, and dust easily accumulates on their surface, affecting the light-receiving area and conversion efficiency of the photovoltaic panels, thereby reducing the utilization efficiency of solar energy and affecting the energy-saving effect. Therefore, regular cleaning and maintenance of photovoltaic panels is essential.

[0004] Currently, cleaning photovoltaic panels installed at high altitudes typically requires workers to climb to these heights, which not only increases the difficulty of the cleaning work but also poses significant safety hazards. Therefore, we have proposed an improvement: an energy-efficient, low-tonnage passenger elevator. Utility Model Content

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0030] As described in the background section, cleaning photovoltaic panels installed at heights usually requires workers to climb to the heights, which not only increases the difficulty of the cleaning work but also poses significant safety hazards.

[0031] To solve this technical problem, this utility model provides an energy-saving, small-tonnage passenger elevator.

[0032] For details, please refer to Figures 1-6 Energy-saving, small-tonnage passenger elevators specifically include:

[0033] An elevator shaft 1 has several solar photovoltaic panels 101 installed on one side. A first column 2 and a second column 201 are fixedly installed on the side of the elevator shaft 1 near the solar photovoltaic panels 101. A cleaning component is installed between the outer surfaces of the first column 2 and the second column 201, and the cleaning component is in contact with the surface of the solar photovoltaic panels 101. A groove 202 is provided at the top of the first column 2, and a through hole 206 is provided at the bottom of the first column 2. A pulley 204 is provided in the groove 202, and a traction rope 205 is provided between the pulley 204 and the through hole 206. Both ends of the traction rope 205 are connected to the cleaning component. The traction rope 205 is used to pull the cleaning component to move, so as to clean the solar photovoltaic panels 101.

[0034] The energy-saving small-tonnage passenger elevator provided by this utility model has a cleaning component installed between the first column 2 and the second column 201. The cleaning component moves up and down under the traction of the traction rope 205 operated by the staff on the ground to clean the solar photovoltaic panel 101. This reduces the need for staff to climb to high places for cleaning operations and greatly reduces the safety hazards in the cleaning process.

[0035] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0036] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0037] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0038] Example 1, please refer to Figures 1-6An energy-saving, small-tonnage passenger elevator includes an elevator shaft 1. A plurality of solar photovoltaic panels 101 are installed on one side of the elevator shaft 1. A first column 2 and a second column 201 are fixedly installed on the side of the elevator shaft 1 near the solar photovoltaic panels 101. A cleaning component is disposed between the outer surfaces of the first column 2 and the second column 201, and the cleaning component is in contact with the surface of the solar photovoltaic panels 101. A groove 202 is formed at the top of the first column 2, and a through hole 206 is formed at the bottom of the first column 2. A pulley 204 is disposed within the groove 202. A traction rope 205 is provided between the through hole 206 and the cleaning component. Both ends of the traction rope 205 are connected to the cleaning component. The traction rope 205 is used to pull the cleaning component to move, so as to clean the solar photovoltaic panel 101. By setting the cleaning component between the first column 2 and the second column 201, the staff operates the traction rope 205 on the ground, so that the cleaning component moves up and down under the pull of the traction rope 205 to clean the solar photovoltaic panel 101. This reduces the need for staff to climb to high places to carry out cleaning work and greatly reduces the safety hazards in the cleaning process.

[0039] Furthermore, a support shaft 203 is installed in the groove 202, and a pulley 204 is sleeved on the outer surface of the support shaft 203. The pulley 204 can be supported by the cooperation between the support shaft 203 and the first column 2.

[0040] Example 2 further optimizes the energy-saving small-tonnage passenger elevator provided in Example 1. Specifically, a blocking component is provided in the groove 202. The blocking component is located above the pulley 204 and is used to block the traction rope 205 to reduce the possibility of the traction rope 205 coming off the pulley 204.

[0041] Furthermore, the blocking component includes a protective plate 213 fixedly installed in the groove 202. The protective plate 213 is slidably connected to the outer surface of the pulley 204. The protective plate 213 can limit the traction rope 205 to the pulley 204, reducing the possibility of the traction rope 205 coming off the pulley 204.

[0042] Example 3 further optimizes the energy-saving small-tonnage passenger elevator provided in Example 1 or 2. Specifically, the cleaning component includes a support part, which is slidably connected between the first column 2 and the second column 201. The cleaning part is provided on the support part, and the support part can support the cleaning part.

[0043] Furthermore, the support includes two sliders 207, which are slidably connected to the outer surfaces of the first column 2 and the second column 201, respectively. The two ends of the traction rope 205 are fixedly connected to the top and bottom of one of the sliders 207. When the traction rope 205 is pulled, the traction rope 205 can drive the slider 207 connected to it to rise and fall, thereby driving the cleaning component to rise and fall.

[0044] Furthermore, the support unit also includes two mounting plates 209. The mounting plates 209 are connected to the sliders 207 by hand-tightening bolts 210. A support plate 211 is fixedly connected between the two mounting plates 209. The side of the support plate 211 closest to the solar photovoltaic panel 101 is connected to the cleaning unit. The support plate 211 can be installed between the two sliders 207 by the cooperation of the hand-tightening bolts 210 and the mounting plates 209. After unscrewing the hand-tightening bolts 210, the support plate 211 and the cleaning unit can be removed, which facilitates the cleaning of the cleaning unit.

[0045] Furthermore, a positioning groove 208 is provided on the slider 207. The inner wall of the positioning groove 208 is inserted into the mounting plate 209. The positioning groove 208 can position the connection between the mounting plate 209 and the slider 207, which facilitates installation.

[0046] Furthermore, the cleaning part is a cleaning brush 212, which contacts the surface of the solar photovoltaic panel 101. The cleaning brush 212 is used to clean the outer surface of the solar photovoltaic panel 101 during movement, reducing the accumulation of dust on the surface of the solar photovoltaic panel 101.

[0047] When in use, pull the traction rope 205, which drives the connected slider 207 to rise and fall, thereby driving the cleaning brush 212 to move up and down. When the cleaning brush 212 moves up and down, it can clean the dust off the surface of the solar photovoltaic panel 101.
