A type of electromechanical dust protection equipment for mining areas

Abstract

This application provides a dustproof and electromechanical protective device for mining areas, relating to the field of dust protection. It includes a base plate, with a housing fixedly connected to its upper surface. Ventilation boxes are provided on both the left and right surfaces of the housing. A cooling fan is installed on the inner wall of each ventilation box, and several fixed shafts are fixedly connected to the inner wall of the ventilation box. Blades are rotatably mounted on the outer surface of each fixed shaft, and the fixed shafts are located eccentrically on the blades. This application utilizes the airflow generated by the cooling fan, which is guided through a specific channel formed by a first straight guide plate, an inclined guide plate, and a second straight guide plate. This allows the airflow to precisely impact the lower half of the blades, using the airflow's own power to drive the blades to rotate around the fixed shafts and open. It eliminates the need for an additional brushless motor and independent electrical control system, relying entirely on aerodynamic force and the blades' own gravity to achieve automatic opening and closing. This significantly reduces equipment manufacturing and maintenance costs while ensuring dustproof performance.

Description

Technical Field

[0001] This utility model relates to the field of dust protection, specifically to a dust protection device for electromechanical equipment in mining areas. Background Technology

[0002] Mining operations generate a large amount of dust. If this dust comes into direct contact with mechanical and electrical equipment, it can cause many problems. On the one hand, dust entering the interior of the equipment will adhere to precision parts, accelerating wear and shortening the equipment's lifespan. On the other hand, dust accumulation can also cause electrical faults, affecting the normal operation of the equipment. Therefore, dust protection equipment is installed on the mechanical and electrical equipment to protect it from dust.

[0003] For example, the Chinese utility model patent with publication number CN223957763U can open or close blades to dissipate heat from electromechanical equipment by rotating a brushless motor and prevent dust from entering during non-use periods. However, the opening or closing of the blades needs to be synchronized with the cooling fan, requiring separate control equipment to start both the brushless motor and the cooling fan simultaneously. Moreover, controlling the opening and closing of the blades solely with a brushless motor will undoubtedly increase equipment and maintenance costs. In view of this, in order to solve the problem of high equipment costs required for blade opening and closing, we propose a dust protection device for electromechanical equipment in mining areas. Utility Model Content

[0004] The purpose of this invention is to solve the problem of high equipment costs required for blade opening and closing.

[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a dust prevention and control device for electromechanical equipment in mining areas, including a base plate. A housing is fixedly connected to the upper surface of the base plate. Ventilation boxes are provided on both the left and right surfaces of the housing. A cooling fan is installed on the inner wall of the ventilation box. Several fixed shafts are fixedly connected to the inner wall of the ventilation box. Blades are rotatably sleeved on the outer surface of the fixed shafts. The fixed shafts are located at the eccentricity of the blades. Several first straight guide plates are fixedly connected to the inner wall of the ventilation box. Inclined guide plates and second straight guide plates are fixedly connected to the inner wall of the ventilation box. The inclined guide plates and second straight guide plates are fixedly connected. A flow-diverting component is provided on the first straight guide plates.

[0006] As a preferred technical solution of this application, the diversion component includes a diversion guide plate, which is fixedly connected to the upper surface of the first flat guide plate. The diversion guide plate is composed of a collection section, a compression section and a discharge section.

[0007] As a preferred technical solution of this application, the discharge section is fixed on the upper surface of the first flat guide plate, and the compression section is fixed between the collection section and the discharge section.

[0008] As a preferred technical solution of this application, the compression section is configured as a straight plate, and the collection section is configured as an inclined plate.

[0009] As a preferred technical solution of this application, the upper surface of the first flat guide plate is provided with a through groove extending to its lower surface, and the gap between the second flat guide plate and the first flat guide plate is aligned with the lower half of the blade.

[0010] As a preferred technical solution of this application, a diffuser cylinder is fixedly connected to the surface of the cooling fan near the blades, and the diffuser cylinder is configured to be conical.

[0011] As a preferred technical solution of this application, the ventilation box is provided with a dustproof plate inside, and the upper surface of the dustproof plate slides through to the upper surface of the ventilation box.

[0012] As a preferred technical solution of this application, the bottom wall of the ventilation box is fixedly connected with two positioning strips, which are located on the left and right sides of the dustproof plate, respectively.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: In the scheme of this application: 1. By coordinating the structures such as the ventilation box, cooling fan, fixed shaft, blades, first straight guide plate, inclined guide plate, second straight guide plate, and diffuser, this application utilizes the airflow generated when the cooling fan is running. After being guided through a specific channel formed by the first straight guide plate, inclined guide plate, and second straight guide plate, the airflow precisely impacts the lower half of the blades. The blades are driven to rotate around the fixed shaft by the airflow's own power to open. There is no need to set up an additional brushless motor and an independent electronic control system. The automatic opening and closing of the blades is achieved entirely by aerodynamic force and the blades' own gravity. While ensuring the dustproof effect, it significantly reduces the equipment manufacturing cost and subsequent maintenance cost. 2. Through the cooperation of the first flat guide plate, the diversion guide plate, the collection section, the compression section, the discharge section, the through slot, and the dustproof plate, this application can divert and guide part of the airflow to the through slot during the process of guiding the airflow to open the blades. This helps to push the blades to a near-horizontal state, ensuring that the blades are fully opened without shaking or half-opening during the operation of the cooling fan. At the same time, the dustproof plate pre-filters the incoming airflow, and the positioning strip ensures the accuracy of the dustproof plate installation position, so that the equipment can maintain a stable dustproof and heat dissipation effect in the long-term high dust environment of the mine.

[0016] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. 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.

[0017] 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.

[0018] 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.

[0019] 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.

[0020] Example 1: Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4A dust prevention and control device for mining areas includes a base plate 1, a housing 2 fixedly connected to the upper surface of the base plate 1, ventilation boxes 3 for installing ventilation components on both the left and right sides of the housing 2, a cooling fan 4 installed on the inner wall of the ventilation box 3, a plurality of fixed shafts 5 for installing components fixedly connected to the inner wall of the ventilation box 3, blades 6 rotatably sleeved on the outer surface of the fixed shafts 5, the fixed shafts 5 being located at the eccentricity of the blades 6, a plurality of first straight guide plates 7 for guiding airflow fixedly connected to the inner wall of the ventilation box 3, an inclined guide plate 8 and a second straight guide plate 9 for reducing the movement space and increasing the flow velocity fixedly connected to the inner wall of the ventilation box 3, the inclined guide plate 8 and the second straight guide plate 9 being fixedly connected, and a flow diversion component being provided on the first straight guide plate 7.

[0021] The housing 2 protects the internal electromechanical equipment, while the ventilation box 3 provides installation space and protection for the ventilation equipment. The cooling fan 4 is responsible for drawing external air into the housing 2 for heat dissipation, while the fixed shaft 5 provides installation space and rotation function for the blades 6. When not in use, the blades 6 are closed to prevent dust from entering. The ventilation channel formed by the first straight guide plate 7, the inclined guide plate 8, and the second straight guide plate 9 can guide air to blow towards the lower side of the blades 6, thereby using high-speed air to make the blades 6 rotate naturally to complete the opening and closing. The fixed shaft 5 is located at the eccentric part of the blades 6, which can make the lower side of the blades 6 sink, so that when the cooling fan 4 is not working, it will automatically droop down to complete the closing.

[0022] Example 2: The electromechanical dust protection equipment for mining areas provided in Example 1 has been further optimized, specifically, as follows: Figure 1 , Figure 2 , Figure 3 , Figure 4 As shown, the diversion assembly includes a diversion guide plate 10, which is fixedly connected to the upper surface of the first straight guide plate 7. The diversion guide plate 10 consists of a collecting section 11, a compression section 12, and a discharging section 13. The discharging section 13 is fixed to the upper surface of the first straight guide plate 7, and the compression section 12 is fixed between the collecting section 11 and the discharging section 13. The compression section 12 is a straight plate, and the collecting section 11 is an inclined plate. The upper surface of the first straight guide plate 7 has a section extending to its lower surface. The through groove 14 on the surface, the gap between the second flat guide plate 9 and the first flat guide plate 7 is aligned with the lower half of the blade 6, the surface of the cooling fan 4 near the blade 6 is fixedly connected to the diffuser cylinder 15, the diffuser cylinder 15 is set in a cone shape, the inside of the ventilation box 3 is provided with a dustproof plate 16, the upper surface of the dustproof plate 16 slides through to the upper surface of the ventilation box 3, and the bottom wall of the ventilation box 3 is fixedly connected to two positioning strips 17, the two positioning strips 17 are respectively located on the left and right sides of the dustproof plate 16.

[0023] The collection section 11, compression section 12, and discharge section 13 on the diversion guide plate 10 can guide some air to the through slot 14 for discharge, thereby opening the auxiliary blades 6 and making the blades 6 nearly horizontal. The diffuser 15 can evenly distribute the air introduced by the cooling fan 4 in the ventilation box 3. The dustproof plate 16 can block dust from entering to a certain extent and reduce the speed of internal dust accumulation. The positioning strip 17 can achieve positioning and limiting after the dustproof plate 16 is inserted. The upper sliding through-hole of the dustproof plate 16 can be directly pulled out when cleaning or replacing the dustproof plate 16.

[0024] The usage process of the electromechanical dust prevention and protection equipment for mining areas provided by this utility model is as follows: After the equipment is installed in place, the base plate 1 serves as the supporting foundation for the entire device and is fixed to the outside of the electromechanical equipment. The shell 2 covers the outside of the electromechanical equipment, forming the first physical barrier to prevent external dust from directly settling on the surface of the electromechanical equipment. When the electromechanical equipment is running and requires heat dissipation, the cooling fans 4 installed on the inner walls of the ventilation boxes 3 on the left and right sides of the shell 2 start to operate.

[0025] When the cooling fan 4 is running, outside air is drawn into the ventilation box 3. The airflow first passes through the dust filter 16, which initially intercepts and filters large dust particles in the air, preventing a large amount of dust from directly entering the equipment. The filtered airflow then enters the diffuser 15, which is a conical structure that diffuses the concentrated high-speed airflow introduced by the cooling fan 4, making the airflow more evenly distributed inside the ventilation box 3.

[0026] The uniform airflow discharged from the diffuser 15 flows along the ventilation channel formed by the first straight guide plate 7, the inclined guide plate 8, and the second straight guide plate 9. Specifically, the airflow first passes over the upper surface of the first straight guide plate 7, then changes its flow direction under the guidance of the inclined guide plate 8, and finally exits through the gap between the second straight guide plate 9 and the first straight guide plate 7. This gap is configured to align with the lower half of the blade 6, so after the airflow exits through this gap, it directly impacts the lower half of the blade 6, using the aerodynamic force generated by the high-speed airflow to push the blade 6 to rotate around the fixed shaft 5 to open. Since the fixed shaft 5 is located at the eccentric position of the blade 6, the lower half of the blade 6 is offset in its natural state. That is, when the cooling fan 4 is not started, the blade 6 automatically droops and closes under its own gravity, sealing the opening of the ventilation box 3 and effectively preventing external dust from flowing back into the housing 2 when the equipment is stopped.

[0027] Meanwhile, the diversion guide plate 10, located on the upper surface of the first flat guide plate 7, diverts the airflow. The diversion guide plate 10 consists of a collection section 11, a compression section 12, and a discharge section 13. A portion of the airflow is captured by the collection section 11 and accelerated and compressed by the narrowing of the channel in the compression section 12. Finally, it is guided through the discharge section 13 to the through slot 14 on the upper surface of the first flat guide plate 7 and discharged from the through slot 14 to the area where the blade 6 is located. This helps to push the blade 6 to open further to a near-horizontal state, ensuring that the blade 6 remains fully open during the operation of the cooling fan 4, so as to ensure that the airflow channel is unobstructed.

[0028] When the cooling fan 4 stops running, the high-speed airflow disappears, and the blades 6 lose their aerodynamic support. At this time, because the fixed shaft 5 is located at the eccentric point of the blades 6, the lower half of the blades 6 is heavier than the upper half. Under the action of gravitational torque, the blades 6 automatically rotate around the fixed shaft 5 to return to the vertical closed position, thus resealing the opening of the ventilation box 3. Throughout the process, the dustproof plate 16, through its structural design that slides through its upper surface to the upper surface of the ventilation box 3, can be pulled upwards and removed without disassembling the entire unit, facilitating regular cleaning or replacement by staff. The two positioning strips 17 fixedly connected to the bottom wall of the ventilation box 3 are located on the left and right sides of the dustproof plate 16, respectively, limiting and guiding the insertion position of the dustproof plate 16, ensuring that the dustproof plate 16 is accurately positioned after each installation, guaranteeing the consistency of its dustproof sealing effect.
