Description

Technical Field

[0001] The utility model relates to an alarm device, in particular to an alarm device for a variable frequency motor strong wind machine, belonging to the technical field of alarm equipment. Background Art

[0002] Electricity resources are secondary energy obtained by converting primary energy. They play a special role in energy development, production, transportation, and consumption. In production and transportation, motors are devices that convert electrical energy into mechanical energy to drive the rotating parts of the equipment. In daily production, the operation of motors will generate heat due to the conversion of energy consumption. If the heat generated by motors running for a long time is not effectively dissipated, it will affect the service life of the motor and even cause the aging and burning of the insulation, thereby affecting production efficiency. Installing a cooling fan at the tail end of the motor can effectively reduce the generation of heat.

[0003] Since the variable frequency motor will generate heat when running for a long time, the installation of a strong fan for heat dissipation is beneficial to extend and improve the service life and working efficiency of the motor, thereby ensuring continuous stable and efficient production operation. However, the strong fan will inevitably be at risk of jamming and damage during continuous operation, which will cause the heat generated by the variable frequency motor to not be effectively and continuously dissipated, resulting in the shortening of the life of the motor or even burning it out, and the interlocking stop between the circuits, thus affecting the production operation. With so many motors and strong fans put into production, manual inspections may not necessarily detect the stop of the strong fan one by one or in a timely manner, so it will also affect production efficiency. Therefore, in order to avoid affecting production efficiency, an alarm device is usually installed on the strong fan. The stop trigger contact signal of the fan circuit is transmitted to the alarm device to trigger the alarm, thereby attracting the attention of production personnel to promptly check and replace the fan.

[0004] However, in order to achieve good heat dissipation, the alarm device will have multiple heat dissipation holes on the device. Long-term use will allow external dust to enter the interior of the device through the heat dissipation holes. However, commonly used alarm devices are not equipped with a dust cleaning function. Dust attached to electronic components will cause them to malfunction, affecting the normal use of the alarm device.

[0005] Therefore, there is an urgent need to improve a variable frequency motor strong wind fan alarm device to solve the above-mentioned problems. Utility Model Content

[0006] The purpose of the utility model is to provide a variable frequency motor strong wind fan alarm device, which can clean the dust entering the inside of the frame through the setting of a dust removal mechanism, thereby preventing the dust from adhering to the intermediate relay and the strong wind fan control circuit contactor, and preventing the intermediate relay and the strong wind fan control circuit contactor from malfunctioning and affecting the normal alarm use.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, rather than all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the utility model.

[0025] like Figure 1-Figure 4 As shown, this embodiment provides an embodiment of a variable frequency motor strong wind blower alarm device.

[0026] A variable frequency motor strong wind blower alarm device comprises a frame 1, a plurality of intermediate relays 2 are fixedly installed inside the frame 1, a plurality of strong wind blower control circuit contactors 3 are installed below the intermediate relays 2, an indicator light 4 is fixedly installed on the front of the frame 1, an alarm 5 is installed on one side of the indicator light 4, a control switch 6 is installed below the alarm 5, a dust removal mechanism 7 is arranged on the frame 1, the dust removal mechanism 7 comprises a vacuum cleaner 8 installed on the top of the frame 1, an air duct 9 connected to the vacuum cleaner 8 is fixedly installed on the top of the frame 1, two electric guide rails 10 are symmetrically installed on the inner wall of the frame 1, a dust collection frame 11 is installed between the two electric guide rails 10, and a plurality of telescopic hoses 12 are installed between the dust collection frame 11 and the air duct 9. By setting the dust removal mechanism 7, the dust inside the frame 1 can be cleaned, the vacuum cleaner 8 is started to generate suction and the dust is absorbed by the dust collection frame 11 placed inside the frame 1, and the two electric guide rails 10 are started to drive the dust collection frame 11 to move up and down, so as to perform comprehensive dust removal and cleaning on the inside of the frame 1. After the dust is cleaned, the intermediate relay 2 and the strong fan control circuit contactor 3 can be avoided from being affected, so as to prevent the fault from affecting the normal alarm use.

[0027] A wire clamp 13 fixedly mounted on the frame 1 is provided between the intermediate relay 2 and the strong wind fan control circuit contactor 3, and a plurality of limit grooves are provided on the wire clamp 13. Two fixing frames 14 are fixedly mounted on the input end of the vacuum cleaner 8, and a screw 15 connected by a thread is provided on the fixing frame 14. A clamp 16 is movably mounted on one end of the screw 15, and the clamp 16 is slidably connected to the fixing frame 14, and a rubber pad 17 is fixedly mounted on the inner wall of the clamp 16. By setting the wire clamp 13, the lines between the intermediate relay 2 and the strong fan control circuit contactor 3 can be classified and bound to avoid multiple groups of lines from being entangled with each other. By setting the fixing frame 14, the screw 15 and the clamping plate 16, the vacuum cleaner 8 can be easily installed and disassembled with the air duct 9. After the input end of the vacuum cleaner 8 is connected to the air duct 9, the screw 15 is rotated to drive the clamping plate 16 to move by the thread until the two clamping plates 16 are attached to the surface of the air duct 9 for clamping, thereby completing the installation and docking of the vacuum cleaner 8 and the air duct 9. When disassembling, the screw 15 can be directly rotated in the opposite direction to disengage the clamping plate 16 from the air duct 9, thereby completing the disassembly of the hostile vacuum cleaner 8 and the air duct 9, making it convenient to remove the vacuum cleaner 8 for cleaning. By setting the rubber pad 17, the friction between the clamping plate 16 and the air duct 9 can be increased, thereby improving the firmness of the clamping.

[0028] The other end of the screw 15 is fixedly mounted with a fixing block 18, a handle 19 is fixedly mounted on the fixing block 18, and anti-skid patterns are arranged on the handle 19. A limit frame 20 is fixedly mounted on the surface of the frame 1, and a positioning block 21 slidably connected to the limit frame 20 is fixedly mounted on the bottom of the fixing block 18. A protective cover 22 is sleeved on the alarm 5, and a notch is provided at one end of the protective cover 22. The setting of the fixing block 18 and the handle 19 facilitates the operation of the screw 15 for rotation, and the setting of the anti-skid patterns can prevent the hand from slipping during operation. The setting of the limit frame 20 and the positioning block 21 can play a role in positioning the installation of the vacuum cleaner 8, so that the vacuum cleaner 8 can be accurately docked with the air duct 9. The setting of the protective cover 22 can protect the alarm 5 and prevent the alarm 5 from being damaged by collision. At the same time, the opening of the notch is conducive to sound propagation.

[0029] In this embodiment, if Figure 1-Figure 4 As shown, the working process of a variable frequency motor strong wind fan alarm device provided in this embodiment is as follows:

[0030] The contactor 3 of the strong wind fan control circuit generates a stop signal which is fed back to the frame 1 to trigger the alarm prompts of the indicator light 4 and the alarm 5 to perform a chain process, thereby prompting and notifying the relevant staff to perform the corresponding alarm reset and replace the corresponding strong wind fan.

[0031] The vacuum cleaner 8 is started to generate suction and absorbs dust through the dust collecting frame 11 placed inside the frame 1. At the same time, the two electric guide rails 10 are started to drive the dust collecting frame 11 to move up and down, so as to perform comprehensive dust removal and cleaning on the inside of the frame 1. After the dust is cleaned, the intermediate relay 2 and the contactor 3 of the strong fan control circuit can be avoided from being affected, so as to prevent the fault from affecting the normal alarm use.

[0032] In summary, in this embodiment, according to a variable frequency motor strong wind fan alarm device of this embodiment, through the setting of the wire clamp 13, the lines between the intermediate relay 2 and the strong wind fan control circuit contactor 3 can be classified and bound to avoid multiple groups of lines from being entangled with each other. Through the setting of the fixing frame 14, the screw 15 and the clamping plate 16, the vacuum cleaner 8 can be easily installed and disassembled with the air duct 9. After the input end of the vacuum cleaner 8 is connected to the air duct 9, the screw 15 is rotated to drive the clamping plate 16 to move by the thread until the two clamping plates 16 are attached to the surface of the air duct 9 for clamping, thereby completing the installation and docking of the vacuum cleaner 8 and the air duct 9. When disassembling, the screw 15 can be directly rotated in the opposite direction to make the clamping plate 16 move from the air duct 9. The upper part is detached to complete the separation of the hostile vacuum cleaner 8 and the air duct 9, so that the vacuum cleaner 8 can be removed for cleaning. The setting of the rubber pad 17 can increase the friction between the clamping plate 16 and the air duct 9 and improve the firmness of the clamping. The setting of the fixing block 18 and the handle 19 can facilitate the operation of the screw rod 15 for rotation. The setting of the anti-slip pattern can avoid the phenomenon of hand slipping during operation. The setting of the limit frame 20 and the positioning block 21 can play a role in positioning the installation of the vacuum cleaner 8, so that the vacuum cleaner 8 can be accurately connected with the air duct 9. The setting of the protective cover 22 can protect the alarm 5 and prevent the alarm 5 from being damaged by collision. At the same time, the opening of the slot is conducive to sound propagation.
