However, in certain environments, such as construction sites and factory production lines, a large amount of dust may accumulate inside the elevator car. This dust not only affects the comfort of the riding environment, but more importantly, when the dust concentration reaches a certain level, there is a potential risk of dust explosion, which seriously threatens the lives of elevator passengers.

[0003] A search revealed Chinese patent application number 202220802303.5, which discloses an explosion-proof elevator, including a car and an installation box. The car is equipped with a pair of opening and closing elevator doors, and infrared photoelectric panels are symmetrically arranged on the inner side of the opening and closing elevator doors. The installation box is located at the bottom of the car, and a dust collection cylinder is provided on the top of the inner wall of the installation box. A dust concentration sensor and a temperature sensor connected to a controller are provided on the left side of the bottom of the dust collection cylinder, and a temporary storage box is provided on the right side. The dust collection cylinder is also connected to a dust extraction fan through a dust extraction pipe, and the dust extraction fan is connected to the temporary storage box through a dust discharge pipe. Both the dust extraction fan and the temporary storage box are fixedly installed at the bottom of the installation box.

[0004] The explosion-proof elevator in the aforementioned patent has the following shortcomings: although the temporary storage box can collect dust, when the collected dust needs to be cleaned, tools such as shovels are required to collect the dust, making it inconvenient to remove it from the temporary storage box. Therefore, there are inconveniences in terms of dust cleaning. Utility Model Content

A plate is fixed to one side of the outer wall of the dust collection assembly, and a slot is provided on the other side of the outer wall of the dust collection assembly. The fastener includes a U-shaped plate and an elastic insert. The U-shaped plate is welded to the inner wall of the top of the elevator car, and the U-shaped plate and the plate cooperate with each other. The elastic insert is installed on the inner wall of the top of the elevator car, and the elastic insert cooperates with the slot.

[0008] As a further embodiment of this utility model: the dust collection component includes a dust collection frame and a strainer, the strainer is welded to the bottom of the dust collection frame, and the adsorption filler is filled inside the dust collection frame.

[0010] As a further embodiment of this utility model: the elastic plug includes a vertical plate and a sliding rod. The vertical plate is fixed to the inner wall of the top of the elevator car, and the sliding rod is movably connected to the inner wall of the through hole opened on the surface of the vertical plate. One end of the sliding rod is fixed with a limiting head that matches the slot, and a spring is engaged between the vertical plate and the sliding rod.

Detailed Implementation

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0027] Example 1: An elevator with explosion-proof function, such as Figures 1 to 5 As shown, the system includes an elevator car 1. A dust collection unit is installed on the top outer wall of the elevator car 1, and a dust collection assembly is installed on the top inner wall of the elevator car 1 via a fastener. A plate 12 is fixed to one side of the outer wall of the dust collection assembly, and a slot 17 is opened on the other side of the outer wall of the dust collection assembly. The fastener includes a U-shaped plate 13 and an elastic insert. The U-shaped plate 13 is welded to the top inner wall of the elevator car 1, and the U-shaped plate 13 and the plate 12 cooperate with each other. The elastic insert is installed on the top inner wall of the elevator car 1, and the elastic insert and the slot 17 cooperate with each other.

[0028] To effectively prevent the elevator car 1 from exploding due to excessive dust concentration during use, a dust collection component and a dust suction unit are used in conjunction. The dust suction unit draws the dust inside the elevator car 1 into the dust collection component for collection. When the dust collection component needs to be installed on the elevator car 1, the insert plate 12 is first inserted into the U-shaped plate 13 to achieve initial positioning on one side of the dust collection component. After insertion, the elastic plug is inserted into the slot 17 to achieve positioning on the other side of the dust collection component, thus completing the fixed connection between the dust collection component and the elevator car 1.

[0029] By installing the dust collection component on the top of the elevator car 1, the disturbance to passengers is reduced, and the dust can be collected when the dust concentration inside the elevator car 1 is too high, thus preventing dust explosion.

[0030] The dust collection assembly includes a dust collection frame 8 and a strainer 18. The strainer 18 is welded to the bottom of the dust collection frame 8, and the adsorption filler 14 is filled inside the dust collection frame 8.

[0031] When it is necessary to collect dust inside the elevator car 1, the suction force generated by the dust collection unit causes the dust to be adsorbed by the adsorption filler 14 through the mesh 18. In this embodiment, the adsorption filler 14 is preferably activated carbon.

[0032] The dust extraction unit includes a mounting plate 2 and a dust extraction fan 3. The mounting plate 2 is fixed to the top outer wall of the elevator car 1 by bolts, and the dust extraction fan 3 is fixed to the top outer wall of the mounting plate 2 by bolts.

[0033] The dust can be extracted from the elevator car 1 by the dust extraction fan 3. The extracted dust is then absorbed by the adsorption filler 14 after passing through the mesh 18.

[0034] The elastic insert includes a vertical plate 5 and a slide rod 11. The vertical plate 5 is fixed to the inner wall of the top of the elevator car 1 by bolts, and the slide rod 11 is slidably connected to the inner wall of the through hole opened on the surface of the vertical plate 5. One end of the slide rod 11 is fixed with a limiting head 15 that is compatible with the slot 17, and a spring 16 is engaged between the vertical plate 5 and the slide rod 11.

[0035] The slot 17 is opened on the side wall of the dust collection frame 8, and the insert plate 12 is welded to the outer wall of the other side of the dust collection frame 8. When the insert plate 12 is inserted into the U-shaped plate 13, the spring force of the spring 16 causes the limiting head 15 to be inserted into the slot 17, thereby fixing the dust collection frame 8 and the strain net 18 to the inner wall of the top of the elevator car 1.

[0036] The controller 6 and the dust concentration sensor 7 are fixed to the inner wall of the top of the elevator car 1 by screws, and the controller 6, the dust concentration sensor 7 and the dust extraction fan 3 are electrically connected.

[0037] Dust concentration sensor 7 samples the air inside the car and measures the dust concentration. When dust concentration sensor 7 detects that the dust concentration has reached a preset threshold exceeding safety standards or a specific warning level, it generates a trigger signal. This trigger signal is transmitted to controller 6 via cable or wirelessly. After receiving the trigger signal from dust concentration sensor 7, controller 6 first verifies the signal to ensure its authenticity and accuracy. The processing unit inside controller 6 decodes the received signal and converts it into a control command. Based on the decoded signal, controller 6 generates a control command. The controller 6 sends control commands to the control circuit of the dust extraction fan 3 through its output port. After receiving the command, the control circuit of the dust extraction fan 3 starts the dust extraction fan 3 to begin extracting air from the car and introduces the dust-containing air into the adsorption packing 14. The controller 6 continuously monitors the operating status of the dust extraction fan 3 to ensure its normal operation. After the dust extraction fan 3 has been running for a period of time, the dust concentration sensor 7 measures the dust concentration again. If the dust concentration is still too high, the controller 6 continues to control the dust extraction fan 3 to run. When the dust concentration drops to a safe range, the controller 6 will control the dust extraction fan 3 to stop running.

[0038] Working principle: The dust concentration sensor 7 samples the air inside the elevator car 1 to accurately measure the dust concentration in the air. First, a safe dust concentration threshold is preset. When the dust concentration detected by the dust concentration sensor 7 exceeds this threshold, an alarm will be triggered and the dust extraction program will be started. Once the dust concentration exceeds the standard, the dust concentration sensor 7 immediately generates a trigger signal and quickly transmits it to the controller 6 via cable or wireless means. After receiving the signal, the controller 6 first verifies it to ensure the authenticity and accuracy of the signal. Then, the processing unit inside the controller 6 decodes the signal and converts it into a control command. Based on the decoded signal, the controller 6 generates a command to control the dust extraction fan 3 to start and sends it to the control circuit of the dust extraction fan through its output port. After receiving the command, the control circuit of the dust extraction fan 3 begins to extract the air in the car. The extracted dust passes through the mesh 18 and is adsorbed by the adsorption packing 14.

[0039] Example 2: An elevator with explosion-proof function, for easy disassembly of the dust collection component, such as... Figures 1 to 5 As shown, this embodiment makes the following additions based on embodiment 1: A seat assembly is installed on one side inner wall of the elevator car 1. The seat assembly includes a seat body 10 and a mounting frame 19. The mounting frame 19 is fixed to the one side inner wall of the elevator car 1 by bolts, and the seat body 10 is rotatably connected between the two inner walls of the mounting frame 19. The seat assembly also includes a support plate 4 fixed to the inner wall of the elevator car 1 by bolts, and the support plate 4 supports the seat body 10.

[0040] When the dust collection component needs to be replaced, in order to facilitate the disassembly of the dust collection component, the seat body 10 is rotated and unfolded along the mounting bracket 19, and the seat body 10 is supported by the support plate 4. Personnel can step on the seat body 10 to disassemble the dust collection component. At the same time, the unfolded seat body 10 also makes it convenient for passengers to rest.

[0041] A limit plate 9 is rotatably connected to the inner wall of one side of the elevator car 1.

[0042] When the seat body 10 is folded, the limiting plate 9 is rotated to the side wall of the seat body 10, thereby using the limiting plate 9 to limit the seat body 10 and ensure the stability of the seat body 10 after folding.

[0043] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
