Description

Technical Field

[0001] The utility model relates to the technical field of elevators, in particular to a moisture-proof control cabinet for an outdoor machine-roomless elevator. Background Art

[0002] An elevator refers to a permanent transportation device that serves several specific floors in a building, and its car runs on at least two columns of rigid tracks perpendicular to the horizontal plane or with an inclination angle less than 15° to the plumb line. There are also step-type ones, where the tread plates are installed on the tracks and run continuously, commonly known as escalators or moving walkways, which are fixed lifting devices serving the specified floors. A vertical lift elevator has a car that runs between at least two columns of vertical or inclined rigid guide rails with an inclination angle less than 15°. Among them, the outdoor machine-roomless elevator is also a type of elevator, and a control cabinet is required for its control.

[0003] In order to ensure the normal heat dissipation of the internal equipment of the existing outdoor machine-roomless elevator control cabinet, ventilation grilles or ventilation openings are usually installed on both sides of the control cabinet. However, while ventilating, the external humid air flow will also enter the control cabinet interior synchronously. With the continuous influx of the humid air flow, it is extremely easy for the equipment in the control cabinet to be affected by moisture and short-circuited, resulting in poor moisture-proof effect of the entire control cabinet and great potential safety hazards. Content of the Utility Model

[0004] The purpose of the utility model is to solve the problem of poor moisture-proof effect in the prior art, and to propose a moisture-proof control cabinet for an outdoor machine-roomless elevator.

[0005] In order to achieve the above purpose, the utility model adopts the following technical scheme:

[0006] A moisture-proof control cabinet for an outdoor machine-roomless elevator, including a control cabinet body. On both sides at the top of the back of the control cabinet body, a plurality of exhaust pipes are sequentially communicated in the up-and-down direction, and an auxiliary one-way valve is arranged on each exhaust pipe. A fixed box and a placement box are sequentially fixed on the back of the control cabinet body in the up-and-down direction. A controller is arranged at the top on the right side of the control cabinet body. An auxiliary dehumidification air intake component is arranged on the control cabinet body, the fixed box and the placement box.

[0007] Preferably, the auxiliary dehumidification air intake assembly includes an air pump fixed in the fixed box. On both sides of the control cabinet body, a plurality of horizontal pipes are sequentially communicated in the up and down direction. On both sides of the bottom of the back surface of the control cabinet body, vertical pipes are fixed through reinforcing members. The top end of the vertical pipe is communicated with a round box. A sealing cover is arranged on the round box. A docking pipe is communicated with the sealing cover. One end of the docking pipe close to the sealing cover is of a telescopic pipe structure. The air outlet end of the air pump is communicated with an air outlet pipe. The end of the air outlet pipe away from the fixed box is rotatably installed at the top end of one of the docking pipes. A first communication frame is rotatably installed on the other docking pipe. Both ends of the first communication frame are communicated with second communication frames. Three ends of each group of second communication frames are communicated with the horizontal pipes. On both sides of the first communication frame close to the other docking pipe, first Venturi tubes are arranged. Three ends of each group of second communication frames are communicated with branch pipes. One end of the branch pipe is communicated with a second Venturi tube and one end of the second Venturi tube is communicated with the horizontal pipe. The vertical pipe is filled with drying balls. A circular activated carbon plate is placed in the round box. A square activated carbon plate and a moisture-absorbing cotton plate are sequentially embedded in the placement box from the inside to the outside. On both sides of the placement box, positioning pipes are communicated and one end of the positioning pipe is communicated with the vertical pipe. A first one-way valve is arranged on each group of horizontal pipes. An isolation filter screen is embedded at one end of each positioning pipe close to the vertical pipe.

[0008] Preferably, an auxiliary Venturi tube is arranged on one of the positioning pipes.

[0009] Preferably, a filling inclined pipe is communicated with the tops of the vertical pipes far away from each other. Auxiliary valves are arranged at the bottom ends of the vertical pipes and on the filling inclined pipes.

[0010] Preferably, L-shaped plates are fixed on both sides of the top of the circular activated carbon plate and the tops of the L-shaped plates are attached to the sealing cover. An external thread is integrally formed on the surface of the sealing cover. An internal thread meshing with the external thread is opened in the round box.

[0011] Preferably, a sealed box door is rotatably installed on one side of the top of the placement box through a hinge.

[0012] Preferably, a flip cover plate cooperating with the controller is rotatably installed on the right side of the control cabinet body. A shielding frame is fixed on the right side of the control cabinet body and the shielding frame is located above the flip cover plate.

[0013] Compared with the prior art, the beneficial effects of the utility model are:

[0014] The inorganic machine room outdoor elevator moisture-proof control cabinet, by setting an auxiliary dehumidification air intake component and using an air pump, can quickly transmit external gas into the horizontal pipe. During the transmission process, the circular activated carbon plate can adsorb the moisture in the gas in advance, and the desiccant balls can further adsorb the moisture in the gas. The design of the isolation filter screen prevents the desiccant balls from entering the positioning pipe. At the same time, the square activated carbon plate and the moisture-absorbing cotton plate can perform a third adsorption of the moisture in the gas. At this time, by using multiple and multi-directional adsorption methods, the moisture in the gas can be removed. Under the acceleration of the first Venturi tube, the dry gas quickly rushes into the control cabinet body, quickly cooling the equipment inside the control cabinet body, preventing the humid gas from damaging the equipment inside the control cabinet body, improving safety. At the same time, the design of the second Venturi tube and the first one-way valve can divert part of the dry gas, making it enter the control cabinet body at a faster speed, thereby forming a certain negative pressure in the horizontal pipe to better draw the dry gas into the control cabinet body, forming a virtuous cycle and improving the cooling effect of the equipment inside the control cabinet body.
