Description

Technical Field

[0001] The present invention relates to the technical field of transportation, and particularly to a fixed armature for transportation equipment. Background Art

[0002] Transportation equipment is a general term for transportation equipment such as railways, roads, and aviation. Since most transportation equipment is used outdoors, the armature of the transportation equipment needs to be suitable for a variety of working environments.

[0003] When the existing fixed armature of transportation equipment is in use, due to long-term outdoor work, in order to avoid overheating of the transportation equipment during long-term operation, it is necessary to dissipate heat from the transportation equipment in a timely manner. However, most traditional heat dissipation methods use external fans for heat dissipation, which consumes too much electrical energy, and the fans also generate a certain amount of heat during long-term operation, resulting in poor heat dissipation effect. Or water cooling is used for heat dissipation, but steam is easily generated during the heat exchange process to achieve heat dissipation, so there is a risk of short circuit, and there are certain safety hazards during the operation of the armature, which needs to be improved. Summary of the Invention

[0004] Aiming at the deficiencies of the prior art, the present invention provides a fixed armature for transportation equipment, which solves the technical problems of excessive electrical energy consumption and poor heat dissipation effect during heat dissipation.

[0005] To solve the above technical problems, the present invention provides the following technical solutions: A fixed armature for transportation equipment includes two symmetrically arranged fixing plates. A mounting groove for placing the armature is provided at the center of each of the two fixing plates. An armature winding mechanism is provided inside the mounting groove. A squeezing heat dissipation mechanism is provided between the two fixing plates, and the squeezing heat dissipation mechanism is located outside the armature winding mechanism. The armature winding mechanism includes an armature core provided at the center inside the mounting groove. A fixing sleeve is fixedly installed on one side of the armature core. A rotating shaft is fixedly connected to the end of one side of the fixing sleeve. A commutator is fixedly installed on the other side of the armature core. Elastic limiting rods are fixedly installed on the outer side wall of the armature core at equal intervals, and the elastic limiting rods are distributed at equal intervals along the axis of the rotating shaft.

[0006] The squeezing heat dissipation mechanism includes rotating columns penetrating through the side walls of the fixing plates. The rotating columns are symmetrically distributed at the four corners of the fixing plates. Elliptical limiting cylinders are rotatably installed on the outer sides of the rotating columns. Elastic squeezing sleeves are fixedly installed between adjacent elliptical limiting cylinders. A ventilation net is provided on the top wall of the side of the elastic squeezing sleeve close to the rotating column. Heat dissipation holes are provided on the inner sides of the elastic squeezing sleeves.

[0007] Further, a number of groups of the heat dissipation holes are equidistantly arranged along the inner circumferential direction of the elastic extrusion sleeve. Each group of the heat dissipation holes is arranged along the tangential direction of the axis of the rotating column, and the opening size of each group of heat dissipation holes gradually decreases along the rotation direction of the armature core.

[0008] Further, sliding sleeves are slidably installed at the centers of the side walls on one side of the major axis inside the elliptical limiting cylinder. Spherical balls are rotatably installed on the outer sides of the sliding sleeves, and a hot steam adsorption mechanism is arranged inside the elliptical limiting cylinder. The hot steam adsorption mechanism includes a first limiting groove opened in the elliptical limiting cylinder for the sliding sleeve to slide, the opening direction of the first limiting groove is perpendicular to the rotating column, second limiting grooves are opened at the inner tops of the first limiting grooves, a storage cylinder for storing lime powder is fixedly installed at the tops of the second limiting grooves, movable ejector rods are movably installed at the bottoms of the storage cylinders, a storage air bag is fixedly connected to the inner top of the storage cylinder, a horizontally arranged extrusion rod is fixedly installed at the outer bottom of the storage air bag, movable rods are fixedly connected to the tops of the movable ejector rods, and the tops of the movable rods penetrate and extend into the interior of the storage air bag.

[0009] Further, an elastic limiting member is sleeved on the outer side of the movable rod, an opening for discharging lime powder is opened in the center of the movable rod, and both ends of the opening are communicated with the storage air bag and the first limiting groove through penetration. The bottom wall of the movable ejector rod is set as an arc surface, the inner side of the sliding sleeve is set as an arc surface, the sliding sleeve is not completely sleeved on the left side of the spherical ball, and a feeding channel is penetrated and opened at the top of the storage air bag.

[0010] By means of the above technical solution, the present invention provides a fixed armature for a transportation device, which at least has the following beneficial effects:

[0011] 1. Through the setting of the extrusion heat dissipation mechanism of the present invention, the heat generated during the operation of the armature of the transportation device is effectively dissipated. At the same time, during the rotation of the armature core, the elastic limiting rod continuously contacts the elliptical limiting cylinder, realizing the reciprocating extrusion and deformation of the elastic extrusion sleeve, achieving the effect of effectively dissipating the hot air flow around the armature core along the ventilation net. Compared with the traditional fan heat dissipation and water cooling heat dissipation, the energy consumption is reduced, and the safety hazard caused by short circuit is reduced.

[0012] 2. When the elliptical limiting cylinder is squeezed and contacted by the elastic limiting rod, the spherical ball is driven to slide along the inside of the first limiting groove, so that the lime powder inside the storage air bag is evenly coated on the surface of the spherical ball, achieving the effective adsorption of the hot steam during the operation of the armature of the transportation device, significantly reducing the short circuit risk, and further improving the safety of the device.

[0013] 3. In the present invention, when the armature core rotates, it continuously contacts the elliptical limiting cylinder, and then contacts the elastic extrusion sleeve through shrinkage deformation. During the contact process, it drives the spherical ball to slide periodically with the sliding sleeve, thereby realizing the periodic coating of lime powder. This achieves uniform coating on the surface of the spherical ball while reducing the friction force during the rotational contact process, reducing the extrusion loss of the elastic extrusion sleeve, increasing the service life of the elastic extrusion sleeve, and having good application prospects.

[0014] 4. In the present invention, the ventilation nets and heat dissipation holes arranged at equal intervals enable the effective dissipation of the internal airflow of the extrusion heat dissipation mechanism. At the same time, by arranging the heat dissipation holes along the gradually changing inner diameter of the elastic extrusion sleeve, when the elliptical limiting cylinder rotates, the internal airflow of the elastic extrusion sleeve flows rapidly along the tangential direction of the elliptical cylinder during rotation, which can effectively increase the airflow velocity and improve the heat dissipation efficiency.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0023] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0024] Embodiment 1:

[0025] Figures 1 - 3 An embodiment of the present invention: A fixed armature for a transportation device, including two symmetrically arranged fixing plates 1. A mounting groove 2 for placing the armature is provided at the center of each of the two fixing plates 1. An armature winding mechanism 3 is provided inside the mounting groove 2. A squeezing heat dissipation mechanism 4 is provided between the two fixing plates 1, and the squeezing heat dissipation mechanism 4 is located outside the armature winding mechanism 3;

[0026] The armature winding mechanism 3 includes an armature core 30 arranged at the center inside the mounting groove 2. A fixing sleeve 31 is fixedly installed on one side of the armature core 30. A rotating shaft 32 is fixedly connected to the end of one side of the fixing sleeve 31. A commutator 33 is fixedly installed on the other side of the armature core 30. Elastic limiting rods 34 are fixedly installed at equal intervals on the outer side wall of the armature core 30. When the armature starts to work, the armature core 30 continuously rotates, so that the elastic limiting rods 34 on its outer side rotate synchronously along the inside of the squeezing heat dissipation mechanism 4. The elastic limiting rods 34 are distributed at equal intervals along the axis of the rotating shaft 32. The equal interval arrangement of the elastic limiting rods 34 enables them to periodically contact the elliptical limiting cylinder 41 inside the squeezing heat dissipation mechanism 4.

[0027] The extrusion heat dissipation mechanism 4 includes rotating columns 40 penetrating and installed on the side wall of the fixed plate 1. The rotating columns 40 are symmetrically distributed at the four corners of the fixed plate 1. Elliptical limiting cylinders 41 are rotatably installed on the outer sides of the rotating columns 40. Elastic extrusion sleeves 42 are fixedly installed between adjacent elliptical limiting cylinders 41. Ventilation nets 43 are provided on the top walls of the elastic extrusion sleeves 42 close to the rotating columns 40. Heat dissipation holes 44 are provided on the inner sides of the elastic extrusion sleeves 42. As the elastic limiting rod 34 rotates and continuously contacts the elliptical limiting cylinder 41, the elliptical limiting cylinder 41 rotates along the rotating column 40. At this time, the elliptical limiting cylinder 41 rotates between the two fixed plates 1, so that the elastic extrusion sleeve 42 between adjacent elliptical limiting cylinders 41 is continuously squeezed and restored, thereby realizing that the air flow inside the elastic extrusion sleeve 42 continuously flows along the heat dissipation holes 44 and the outside of the ventilation net 43, so as to effectively dissipate the hot air flow during the operation of the armature. Through the setting of the extrusion heat dissipation mechanism 4, the heat generated during the operation of the armature of the transportation equipment is effectively dissipated. At the same time, during the rotation of the armature core 30, the elastic limiting rod 34 continuously contacts the elliptical limiting cylinder 41, realizing the reciprocating squeezing deformation of the elastic extrusion sleeve 42, achieving the effect of effectively dissipating the hot air flow around the armature core 30 along the ventilation net 43. Compared with the traditional fan heat dissipation and water cooling heat dissipation, the energy consumption is reduced and the safety hazard caused by short circuit is reduced.

[0028] Embodiment 2:

[0029] Figure 3 This is an embodiment of the present invention: A plurality of groups of heat dissipation holes 44 are equidistantly arranged along the circumferential direction of the inner side of the elastic extrusion sleeve 42. Each group of heat dissipation holes 44 is arranged along the tangential direction of the axis of the rotating column 40. When the elliptical limiting cylinder 41 rotates when contacted by the elastic limiting rod 34, each elliptical limiting cylinder 41 contacts along the rotating column 40. The opening direction of each group of heat dissipation holes 44 ensures that the air flow inside the elastic extrusion sleeve 42 continuously flows along the tangential direction when the elliptical limiting cylinder 41 rotates, accelerating the air flow velocity inside the elastic extrusion sleeve 42 and improving the heat dissipation efficiency. The opening size of each group of heat dissipation holes 44 gradually decreases along the rotation direction of the armature core 30. When the armature core 30 rotates, it drives the elastic extrusion sleeve 42 to rotate periodically in a small amplitude. At this time, the extrusion degree of each part of the elastic extrusion sleeve 42 is different, and the deformation of the elastic extrusion sleeve 42 on the side that first contacts the elastic elliptical limiting cylinder 41 is larger. Therefore, the arrangement that the opening size of each group of heat dissipation holes 44 gradually decreases along the rotation direction of the armature core 30 ensures that the air flow velocity at each part inside the elastic extrusion sleeve 42 is the same. Through the equidistantly arranged ventilation nets 43 and heat dissipation holes 44, the air flow inside the extrusion heat dissipation mechanism 4 is effectively dissipated. At the same time, through the gradually changing distribution of the heat dissipation holes 44 along the inner diameter of the elastic extrusion sleeve 42, when the elliptical limiting cylinder 41 rotates, the air flow inside the elastic extrusion sleeve 42 rapidly flows along the tangential direction when the elliptical cylinder 41 rotates, which can effectively improve the air flow velocity and improve the heat dissipation efficiency.

[0030] Example 3:

[0031] Figures 4 - 6 This is an embodiment of the present invention: Sliding sleeves 46 are slidably installed at the centers of the side walls on one side of the major axis inside the elliptical limiting cylinder 41. Spherical balls 45 are rotatably installed on the outer sides of the sliding sleeves 46. A hot steam adsorption mechanism is provided inside the elliptical limiting cylinder 41.

[0032] The hot steam adsorption mechanism includes a first limiting groove 47 opened in the elliptical limiting cylinder 41 for the sliding sleeve 46 to slide. The opening direction of the first limiting groove 47 is perpendicular to the rotating column 40. Second limiting grooves 48 are opened at the inner tops of the first limiting grooves 47. A storage cylinder 49 for storing lime powder is fixedly installed at the top of the second limiting groove 48. Each time the elastic limiting rod 34 contacts the elliptical limiting cylinder 41 during rotation, the elastic limiting rod 34 contacts the spherical ball 45, causing the spherical ball 45 to roll along the side wall of the sliding sleeve 46.

[0033] Moving ejector rods 491 are movably installed at the bottoms of the storage cylinders 49. The inner tops of the storage cylinders 49 are fixedly connected with storage air bags 492. A horizontally arranged extrusion rod 493 is fixedly installed at the outer bottom of the storage air bag 492. The tops of the moving ejector rods 491 are fixedly connected with moving rods 494. The tops of the moving rods 494 penetrate and extend into the interior of the storage air bag 492. The impacted spherical ball 45 slides along the inside of the first limiting groove 47, causing the inner side wall of the sliding sleeve 46 to contact the extrusion rod 493, thereby causing the extrusion rod 493 to squeeze the storage air bag 492, and further causing the storage air bag 492 to be compressed. At this time, the interior of the storage air bag 492 is in a negative pressure state. When being pressed, the lime powder stored inside flows out through the central opening of the moving rod 494, causing the lime powder to be evenly coated on the outer side of the spherical ball 45. When the elliptical limiting cylinder 41 is driven to contact the elastic limiting rod 34 and is squeezed, the spherical ball 45 slides along the inside of the first limiting groove 47, and further causes the lime powder inside the storage air bag 492 to be evenly coated on the surface of the spherical ball 45, achieving effective adsorption of the hot steam during the operation of the armature of the transportation equipment, significantly reducing the short - circuit risk, and further improving the safety of the equipment.

[0034] Example 4:

[0035] Figures 4 - 6An embodiment of the present invention: An elastic limiting member 495 is sleeved outside the movable rod 494. When the movable rod 494 slides under pressure, the elastic limiting member 495 is compressed. An opening for discharging lime powder is provided at the center of the movable rod 494. Both ends of the opening are respectively communicated with the storage airbag 492 and the first limiting groove 47 in a penetrating manner. After the lime powder flows out along the internal opening of the movable rod 494, when the elastic limiting rod 34 rotates to no longer contact the elliptical limiting cylinder 41, at this time, the sliding sleeve 46 does not contact the movable ejector rod 491, and the circularly compressed elastic limiting member 495 resumes, thereby enabling the movable ejector rod 491 to resume its initial position. When the sliding sleeve 46 contacts the movable ejector rod 491 again, the above-mentioned lime powder discharging process is repeated. When the armature core 30 rotates and continuously contacts the elliptical limiting cylinder 41, and then contacts the contraction deformation of the elastic extrusion sleeve 42, during the contact process, the spherical ball 45 and the sliding sleeve 46 are driven to slide periodically, thereby realizing the periodic coating of lime powder, achieving uniform coating on the surface of the spherical ball 45 while reducing the friction force during the rotational contact process, reducing the extrusion loss of the elastic extrusion sleeve 42, and improving the service life of the elastic extrusion sleeve 42, having good application prospects.

[0036] The bottom wall of the movable ejector rod 491 is provided with an arc surface, and the inner side of the sliding sleeve 46 is provided with an arc surface to ensure that when the sliding sleeve 46 contacts the movable ejector rod 491, the movable ejector rod 491 is driven to slide along the inside of the storage cylinder 49. The sliding sleeve 46 is not completely sleeved on the left side of the spherical ball 45. The sliding sleeve 46 is not completely sleeved on the left side of the spherical ball 45, ensuring that the lime powder discharged through the opening of the movable rod 494 coats the left side wall of the spherical ball 45. As the spherical ball 45 rotates intermittently and continuously, uniform coating of the limestone raw material is realized. A feeding channel 496 is provided through the top of the storage airbag 492 to replenish the raw materials inside the storage airbag 492 in time when the raw materials are insufficient.

[0037] The control mode of the present invention is automatically controlled by a controller. The control circuit of the controller can be realized by simple programming by those skilled in the art. The provision of power also belongs to the common knowledge in the art. And the present invention is mainly used to protect mechanical devices, so the control mode and circuit connection of the present invention will not be explained in detail.
