Description

Technical Field

[0001] The utility model relates to the technical field of soft starters, in particular to a novel industrial intelligent control electric soft starter. Background Art

[0002] A soft starter is a motor control device that integrates motor soft starting, soft stopping, light load energy saving and multiple protection functions. It not only realizes smooth and impact-free starting of the motor during the entire starting process, but also can adjust the parameters of the starting process according to the characteristics of the motor load, such as current limiting value, starting time, etc. In the industrial field, electric soft starters for intelligent control have been widely used, which can realize smooth starting of the motor and facilitate protection of the device.

[0003] Most existing electric soft starters use cooling fans to dissipate heat. A dust filter is arranged outside the cooling fan to filter external dust. However, as the use time increases, the dust adhered to the dust filter will gradually increase, causing the mesh of the dust filter to be blocked, affecting the heat dissipation effect of the electric soft starter.

[0004] Therefore, we proposed a new type of industrial intelligent control power soft starter to solve the above problems. Utility Model Content

[0007] (II) Technical solution

[0008] In order to achieve the above objectives, the present invention is implemented through the following technical solutions:

[0009] A novel industrial intelligent control electric soft starter comprises a soft starter body, cooling fans are arranged on both sides of the soft starter body, dust filters are arranged outside the cooling fans, and a cleaning mechanism for cleaning dust on the dust filters is arranged between the dust filters and the soft starter body.

[0010] Furthermore, the cleaning mechanism includes a movable plate and a fixed plate relatively installed on both sides of the soft starter body, the movable plate is provided with a slot for clamping a dust filter, one end of the movable plate close to the soft starter body is connected to the side wall of the soft starter body through a plurality of compression springs, and a plurality of convex teeth are arranged at intervals on the other end of the soft starter body, a sliding rod is slidably installed on the fixed plate, and a rotating ring rollingly connected to the convex teeth is rotatably installed on the sliding rod.

[0011] Furthermore, a limiting sliding groove is provided on the fixing plate along the distribution direction of the plurality of convex teeth, the sliding rod is slidably installed in the limiting sliding groove, and both ends of the sliding rod extend to the outside of the limiting sliding groove.

[0012] Furthermore, the side wall of the rotating ring is tangent to the side walls of two adjacent convex teeth respectively.

[0013] Preferably, both ends of the soft starter body are provided with limit baffles, and the limit baffles are slidably connected to both ends of the movable plate.

[0014] Preferably, the horizontal height of the top of the dust filter is greater than the horizontal height of the top wall of the limiting baffle.

[0015] (III) Beneficial effects

[0016] Compared with the prior art, the beneficial effects of the utility model are:

[0017] By arranging cooling fans on both sides of the soft starter body to dissipate the heat generated when the soft starter is working to the outside, the dust filter screen blocks and filters the external dust. By adding a cleaning mechanism between the soft starter body and the dust filter screen, when the dust on the dust filter screen increases, the slide rod in the cleaning mechanism can be slid to make the rotating ring on it roll on multiple convex teeth, and at the same time cooperate with the compression spring to make the compression spring continuously repeat the compression-extension movement, so that the dust on the dust filter screen is shaken off to prevent the dust from clogging the mesh of the dust filter screen.

DETAILED DESCRIPTION

[0023] The technical solutions in the embodiments of the utility model will be described clearly and completely below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are only a part of the embodiments of the utility model, rather than all of the embodiments. It should be noted that the words "front", "back", "left", "right", "up" and "down" used in the following description refer to the directions in the drawings, and the words "bottom surface" and "top surface", "inside" and "outside" refer to the directions toward or away from the geometric center of a specific component, respectively. 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.

[0024] See also Figure 1-4 As shown, the utility model provides a novel industrial intelligent control electric soft starter, including a soft starter body 1, a dust filter 3 and a cleaning mechanism 4. Mounting plates 11 are provided at both upper and lower ends of the back of the soft starter body 1. Mounting holes 12 are provided on the mounting plates 11, and the soft starter body 1 can be fixed by passing bolts through the mounting holes 12. A plurality of cooling fans 2 are provided on both sides of the soft starter body 1 to dissipate the heat generated by the soft starter body 1 when working to the outside. The dust filter 3 is located on the outside of the cooling fan 2 to block and filter external dust. A cleaning mechanism 4 for cleaning dust on the dust filter 3 is provided between the dust filter 3 and the soft starter body 1.

[0025] like Figure 2 and Figure 3 As shown, the cleaning mechanism 4 includes a movable plate 41, a compression spring 43, a plurality of convex teeth 44, a fixed plate 45, a slide rod 47 and a rotating ring 48. The movable plate 41 and the fixed plate 45 are symmetrically provided with two, wherein the fixed plates 45 are fixedly connected to the side wall of the soft starter body 1, the movable plate 41 is located on the inner side of the fixed plate 45, and its side wall is provided with a card slot 42 for clamping the dust filter 3, and a plurality of compression springs 43 are provided at one end close to the soft starter body 1, and the compression spring 43 is fixed to the side wall of the soft starter body 1 at one end away from the movable plate 41, and a plurality of convex teeth 44 with a trapezoidal cross section are fixed at the other end of the movable plate 41 at intervals, and a limiting slide groove 46 is provided on the fixed plate 45, and a slide rod 47 with two ends extending to the outside thereof is slidably installed in the limiting slide groove 46, and a rotating ring 48 is rotatably installed on the slide rod 47, and the side wall of the rotating ring 48 is tangentially abutted against the side walls of two adjacent convex teeth 44 under normal conditions.

[0026] By moving the slide bar 47 to slide in the limiting slide groove 46, the rotating ring 48 rolls on the convex tooth 44 when the slide bar 47 slides. When rolling to the top surface of the convex tooth 44, the compression spring 43 contracts. When rolling between the two convex teeth 44, the compression spring 43 extends, so that the compression spring 43 repeats the contraction-extension movement with the movement of the slide bar 47, thereby driving the movable plate 41 and the dust filter 3 to repeat this movement continuously, so that the dust on the dust filter 3 is continuously shaken off and blown to the outside with the operation of the cooling fan 2 to prevent the mesh of the dust filter 3 from being blocked. The dust filter 3 is prevented from being installed on the movable plate 41 by a card connection, which is convenient for replacing the dust filter 3.

[0027] As a preferred technical solution of the utility model: limit baffles 5 are provided at both ends of the soft starter body 1, the limit baffles 5 are slidably connected to the two ends of the movable plate 41, and the top of the dust filter 3 protrudes from the limit baffles 5. The setting of the limit baffles 5 can prevent foreign debris from entering the interior of the soft starter body 1 from the gap between the dust filter 3 and the two ends of the soft starter body 1, and can also play a certain guiding role in the movement direction of the movable plate 41.
