Technical Field

[0001] The utility model relates to power supply and distribution facilities, and more specifically, to a centralized control device for fans in a delivery area of ​​a sorting workshop. Background Art

[0002] With the improvement of hardware equipment in cigarette sorting enterprises, fans have also been installed in the shipping area of ​​the sorting workshop. This is mainly because in the hot summer, workers in the shipping area of ​​the sorting workshop need to withstand high temperatures outside when carrying goods. Without fans to cool down and dissipate heat, workers will sweat profusely, which not only increases the risk of heat stroke, but also makes it easy for their sweat to drip and adhere to the outer packaging of cigarettes to be shipped. After the fans were installed, these problems have been basically solved.

[0003] Since sorting workshops generally have multiple delivery areas, some cigarette sorting companies have more than dozens of delivery areas, and the distance between the fans at both ends of the sorting workshop is even more than 100 meters. Therefore, the centralized control method is currently used. That is, all the gear shifters are placed in the distribution box at one end of the sorting workshop close to the management office, so that the unified management of the fans can be facilitated. However, after opening the distribution box to operate the gear shifter, the box door is often forgotten to be closed, which is not conducive to the safety regulations of on-site operations and poses a safety hazard.

[0017] The utility model is further described below in conjunction with the embodiments, but does not constitute any limitation to the utility model. Any limited modifications made by anyone within the scope of the claims of the utility model are still within the scope of the claims of the utility model.

[0018] See also Figure 1-Figure 3 The utility model provides a centralized control device for fans in the delivery area of ​​a sorting workshop, comprising a box 1 installed at one end of the delivery area of ​​the sorting workshop. An air switch 4 is installed in the box 1 as a master switch of a fan gear 3. A box door 2 is hingedly installed on one side of the box 1, a plurality of fan gears 3 are installed in the box 1, an automatic retractor 5 is installed in the box 1, a connecting block 7 is installed on the side of the box door 2 close to the box 1, a pull rope 6 is installed in the automatic retractor 5, and the end of the pull rope 6 is fixed on the connecting block 7.

[0019] When the door 2 is opened, the pull cord 6 is pulled out from the automatic retractor 5 to adapt to the opening of the door 2. Then the door 2 is blocked to prevent it from closing under the pulling force of the automatic retractor 5, and the corresponding fan gear 3 is operated to start / stop / shift the fan on the corresponding delivery area. After the operation is completed, the door 2 is released, and the door 2 is pulled and finally closed under the action of the automatic retractor 5 to reel in the pull cord 6, thereby solving the problem of forgetting to close the door 2 in the prior art.

[0020] The automatic retractor 5 used in this embodiment is a prior art, for example, an automatic retractor such as that in a measuring tape, or an automatic retractor disclosed in publication number CN203387651U can be used. This embodiment uses the automatic retractor described in CN203387651U, and only needs to replace the wire with a pull rope 6, such as a nylon rope. However, it should be noted that after the door 2 is opened, there is no need to operate the locking switch on the automatic retractor 5 to avoid the situation where the door 2 cannot be closed later.

[0021] When the door 2 is pulled by the pull rope 6 and the automatic retractor 5, the moving speed of the door 2 will gradually increase. In order to prevent the door 2 from colliding with the box body 1 at a high speed, a damping rod 9 is provided between the box body 1 and the door 2 of this embodiment, and both ends of the damping rod 9 are rotatably installed in the box body 1 and the door 2. The damping effect of the damping rod 9 on the movement of the door 2 plays a role in reducing the moving speed of the door 2 and reducing the impact force when it collides with the box body 1. It should be noted that the damping force generated by the damping rod 9 should be smaller than the contraction force of the automatic retractor 5 on the pull rope to avoid the situation where the door 2 cannot be closed.

[0022] In order to improve the stability of winding / unwinding the drawstring 6, a wire sleeve 8 is fixedly installed in the box body 1 and the box door 2 of the present embodiment, and the drawstring 6 is inserted into the wire sleeve 8. The drawstring 6 is positioned by the wire sleeve 8. In addition, a chamfered structure 14 is provided at the edge of the inner hole of one end of the wire sleeve 8 near the hinge of the box door 2 and the box body 1, which can effectively reduce the friction between the drawstring 6 and the edge of the wire sleeve 8, which is beneficial to the service life of the drawstring 6.

[0023] In this embodiment, bearings 10 are fixedly installed in the box body 1 and the box door 2, and a connecting column is installed in the inner ring of the bearing 10 with an interference fit. A mounting block 11 is fixed on the connecting column. The two ends of the damping rod 9 are fixedly connected to the two mounting blocks 11 in a one-to-one correspondence, thereby realizing the rotatable installation of the damping rod 9, so that it can adapt to the change in angle when the box door 2 is opened and closed by rotating the end.

[0024] Preferably, a magnet 12 is fixedly provided at one end of the box body 1 away from the box door 2 and the hinge of the box body 1, and a magnet 2 13 matching the position of the magnet 12 is fixedly provided on the box door 2. When the box door 2 is closed on the box body 1, the two magnets attract each other, thereby positioning the box door 2 and preventing it from being blown open by the wind. In addition, a rubber sheet is attached to the surface of the magnet 12 to isolate the two magnets, buffer the impact force generated by the two magnets, and protect the magnets.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that for those skilled in the art, several modifications and improvements can be made without departing from the structure of the present invention, which will not affect the effect of the implementation of the present invention and the practicality of the patent.
