Description

Technical Field

[0001] The utility model relates to the technical field of elevator monitoring equipment, in particular to a device for monitoring the service life of elevator components. Background Art

[0002] The internal structure of the elevator is the core of the elevator, including the frequency converter, brake, buffer, safety clamp, speed limiter, introduction device, automatic switch, transformer, rectifier, knife switch, transfer switch, contactor, electromagnetic relay, selector, master electrical appliance, terminal switch, door interlocking contacts, brake electromagnet, light signal panel, floor light signal, signal display, signal bell, guide rail, stairwell, machine room, car elevator, platform, counterweight, etc.

[0003] The service life of different parts of an elevator varies during use. In order to monitor the service life of elevator parts in real time, an elevator part service life monitoring device is usually installed on the top of the elevator. For example, Publication No. CN209957165U discloses an elevator part service life monitoring device, comprising: a warning light disposed on the top of the elevator car and capable of displaying different colors; and a control device disposed on the top of the elevator car and adapted to control the display color of the warning light. When the actual service life of an expired elevator part has reached or exceeded its predetermined service life, the control device controls the warning light to display a first color, thereby ensuring that the expired elevator part can be replaced in a timely manner, thereby improving the safety of the elevator. However, in actual operation, this may result in the following problems:

[0004] 1. Since the control panel and warning lights are integrated into a monitoring cabinet, and the signal transmission inside the elevator shaft is weak, the monitoring equipment uses a high-power signal generator to transmit the monitoring data to the outside. This increases the heat dissipation of multiple components inside the monitoring cabinet. At the same time, the monitoring cabinet does not have active heat dissipation and temperature control equipment, so a design that can actively dissipate heat inside the monitoring cabinet is needed.

[0005] 2. Since the elevator is used in the elevator shaft, sewage will seep into the elevator shaft from the elevator entrance, causing sewage to seep into the monitoring cabinet on the top of the elevator, affecting the operation of its internal monitoring equipment. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, the inventors have conducted in-depth research and completed the present utility model after paying a lot of creative work.

[0007] Specifically, the technical problem to be solved by the present invention is to provide an elevator component service life monitoring device to solve the technical problems of poor heat dissipation and waterproofing effects of the current monitoring cabinets used for elevator component service life monitoring equipment.

[0008] In order to solve the above technical problems, the present invention provides the following technical solutions:.

[0009] An elevator component service life monitoring device includes a monitoring cabinet, wherein a heat dissipation mechanism is fixedly mounted on the outer surface of the monitoring cabinet;

[0010] The heat dissipation mechanism includes an air intake assembly, which includes an air intake rack. The right side of the air intake rack is connected to the outer surface of the monitoring cabinet. The air intake assembly also includes an air intake pipe. The left side of the air intake pipe is connected to the inner wall of the monitoring cabinet.

[0011] As an improved technical solution, the heat dissipation mechanism also includes an air intake drive assembly, the outer surface of which is connected to the bottom end of the air intake pipe, and the heat dissipation mechanism also includes an air outlet drive assembly, the outer surface of which is fixedly connected to the inner surface of the monitoring cabinet.

[0012] As an improved technical solution, the air intake drive assembly and the air outlet drive assembly both include an air box, a fixing frame is fixedly installed on the inner surface of the air box, a motor is fixedly installed on the inner surface of the fixing frame, a rotating shaft is fixedly installed on the output end of the motor through a reducer, and heat dissipation blades are fixedly installed on the outer surface of the rotating shaft.

[0013] As an improved technical solution, the heat dissipation mechanism also includes an automatic sealing component, which includes a torsion spring, one end of which is fixedly connected to the inner wall of the monitoring cabinet. The automatic sealing component also includes a rotating rod, the outer surface of which is rotatably connected to the inner surface of the monitoring cabinet, the outer surface of which is fixedly connected to the other end of the torsion spring, and a sealing plate is fixedly installed on the outer surface of the rotating rod.

[0014] As an improved technical solution, a blocking block is fixedly installed on the inner wall of the monitoring cabinet.

[0015] As an improved technical solution, a filter moisture absorber is fixedly mounted on the inner surface of the air intake frame.

[0016] After adopting the above technical solution, the beneficial effects of the utility model are:

[0017] 1. The utility model adds a design for active heat dissipation of the monitoring equipment. Through the coordinated use of the motor and the rotating shaft with the heat dissipation blades and the air box, and through the coordinated use of the air intake frame and the air intake pipe, the heat dissipation gas can be blown in from the bottom of the monitoring cabinet and blown out from the top of the monitoring cabinet, thereby improving the heat dissipation effect in the monitoring cabinet and preventing the heat emitted by the elevator component service life monitoring device in the monitoring cabinet from being unable to volatilize, thereby affecting the use of the monitoring equipment.

[0018] 2. The utility model increases the waterproof design of the monitoring cabinet and uses the air intake frame and the filter moisture absorber in combination to block the water vapor during heat dissipation. The torsion spring and the rotating rod are used in combination with the sealing plate and the blocking block to keep the interior of the monitoring cabinet sealed during heat dissipation, thereby preventing external sewage and water vapor from penetrating into the monitoring cabinet and causing damage to the components of the monitoring electronic equipment.

[0031] like Figure 1 and Figure 2 As shown together, this embodiment provides an elevator component service life monitoring device, which includes a monitoring cabinet 1, and a heat dissipation mechanism 2 is fixedly installed on the outer surface of the monitoring cabinet 1;

[0032] The heat dissipation mechanism 2 includes an air intake assembly 21, which includes an air intake frame 211. The right side of the air intake frame 211 is connected to the outer surface of the monitoring cabinet 1. The air intake assembly 21 also includes an air intake pipe 212. The left side of the air intake pipe 212 is connected to the inner wall of the monitoring cabinet 1.

[0033] like Figure 1 and Figure 2 As shown together, the heat dissipation mechanism 2 also includes an air intake drive component 22, the outer surface of the air intake drive component 22 is connected to the bottom end of the air intake pipe 212, and the heat dissipation mechanism 2 also includes an air outlet drive component 23, the outer surface of the air outlet drive component 23 is fixedly connected to the inner surface of the monitoring cabinet 1.

[0034] like Figure 2 and Figure 4 As shown together, the air intake drive assembly 22 and the air outlet drive assembly 23 both include an air box 24, a fixing frame 25 is fixedly mounted on the inner surface of the air box 24, a motor 26 is fixedly mounted on the inner surface of the fixing frame 25, a rotating shaft 27 is fixedly mounted on the output end of the motor 26 through a reducer, and a heat dissipation blade 28 is fixedly mounted on the outer surface of the rotating shaft 27.

[0035] The motor 26 is electrically connected to an external power source and is controlled by an external PLC programming program.

[0036] like Figure 3 and Figure 4 As shown together, the heat dissipation mechanism 2 also includes an automatic sealing component 29, which includes a torsion spring 291, one end of which is fixedly connected to the inner wall of the monitoring cabinet 1, and the automatic sealing component 29 also includes a rotating rod 292, the outer surface of which is rotatably connected to the inner surface of the monitoring cabinet 1, the outer surface of which is fixedly connected to the other end of the torsion spring 291, and a sealing plate 293 is fixedly installed on the outer surface of the rotating rod 292.

[0037] like Figure 3 and Figure 4 As shown together, a blocking block 294 is fixedly installed on the inner wall of the monitoring cabinet 1.

[0038] The blocking block 294 can limit the rotation radius of the sealing plate 293 so that the plurality of sealing plates 293 can be neatly closed.

[0039] like Figure 1 and Figure 4 As shown together, a filter moisture absorber 3 is fixedly mounted on the inner surface of the air inlet frame 211 .

[0040] The filter desiccant 3 absorbs moisture. When no heat is dissipated in the monitoring cabinet 1, the moisture absorbed by the filter desiccant 3 will be affected by the force and penetrate out from the bottom of the filter desiccant 3 and drip onto the elevator box beam.

[0041] When in use, the electronic components in the monitoring cabinet 1 will generate a lot of heat. At this time, the air inlet drive assembly 22 and the air outlet drive assembly 23 are started, and the motor 26 drives the heat dissipation blades 28 to rotate through the rotating shaft 27, so that the external air first passes through the filter desiccant 3 in the air inlet frame 211, and then enters the monitoring cabinet 1 from the air box 24 through the air inlet pipe 212 to dissipate heat inside, and is sucked out of the monitoring cabinet 1 by the heat dissipation blades 28 of the air outlet drive assembly 23, so that the air flow speed in the monitoring cabinet 1 is high. The air first passes through the filter desiccant 3, so that the moisture in the air is adsorbed by the filter desiccant 3, so that water molecules cannot enter the monitoring cabinet 1. At the same time, when the air enters the monitoring cabinet 1, the gas will drive the sealed plate 293 to rotate when it is inhaled or blown out, so that the gas can enter or discharge the monitoring cabinet 1. The torsion spring 291 drives the rotating rod 292 to rotate, and the rotating rod 292 drives the sealed plate 293 to rotate, so that the inside of the monitoring cabinet 1 dissipates heat and maintains a closed state, so that external moisture or water cannot penetrate into the monitoring cabinet 1.

In addition, it should be understood that after reading the technical content of the present invention, those skilled in the art may make various changes, modifications and / or variations to the present invention, and all such equivalent forms also fall within the scope of protection defined by the appended claims.
