Description

Technical Field

[0001] This utility model belongs to the field of energy harvesting, and specifically relates to a pipeline distribution device. Background Technology

[0002] Valves are widely used as standard components in various pipelines. However, in some non-standard scenarios, standard valves are not suitable, requiring customized pipeline distribution devices. In some automated distribution devices, one actuator is typically used to control the on / off state of each port. In certain special scenarios, two on / off ports are needed, and they need to be alternately on and off—that is, when one is on, the other is off, and when one is off, the other is on. Currently, two actuators are used to complete the two controls. This has at least two drawbacks: firstly, the control cost is relatively high due to the need for two actuators; secondly, synchronizing the two controls is prone to errors. Utility Model Content

[0025] The components include: body 1, cavity 1a, outlet 1b, connecting port 1c, inlet 1d, slide 1e, first cover plate 2, first rotating shaft 2a, second cover plate 3, second rotating shaft 3a, drive unit 4, drive motor 4a, drive gear 4b, two side racks 4c, driven gear 4d, fixing frame 5, and sealing ring 6. Detailed Implementation

[0026] Example 1

[0027] like Figure 1-4 As shown, this embodiment includes a body 1, a first cover plate 2, a second cover plate 3, and a drive unit 4.

[0028] The body 1 adopts a cubic structure, with two cubic cavities 1a symmetrically arranged. A connecting opening 1c is provided between the cavities 1a. Each cavity 1a has an inlet 1d and an outlet 1b, located opposite each other. The inlet 1d of both cavities 1a is located on the same face of the body 1, and the outlet 1b is also located on the same face of the body 1. In other embodiments, the body 1 may also adopt other polygonal prism or cylindrical shapes. In other embodiments, the inlet 1d and outlet 1b can be interchanged.

[0029] In this embodiment, the first cover plate 2 has a first rotating shaft 2a at one end. The first rotating shaft 2a is rotatably fixed in one of the cavities 1a. Rotating the first rotating shaft 2a allows the first cover plate 2 to switch between covering the connecting opening 1c inside the cavity 1a and covering the outlet 1b inside the cavity 1a. Since the two cavities 1a are symmetrical cubic shapes and the connecting opening 1c is located on the common surface of the two cavities 1a, the first rotating shaft 2a rotates 90° when the first cover plate 2 switches.

[0030] Similarly, one end of the second cover plate 3 is provided with a second rotating shaft 3a, which can be rotatably fixed in another cavity 1a. The rotation of the second rotating shaft 3a can cause the first cover plate 2 to switch between covering the communication port 1c in the cavity 1a and covering the outlet 1b of the cavity 1a. When the second cover plate 3 switches, the second rotating shaft 3a also rotates 90°.

[0031] In this embodiment, the second cover plate 3 has the same size and specifications as the first cover plate 2, and the installation position of the second cover plate 3 is symmetrical to the installation position of the first cover plate 2.

[0032] Furthermore, the first cover plate 2 is provided with sealing rings 6 on both sides corresponding to the connection port 1c and the outlet 1b of one of the cavities 1a; the second cover plate 3 is also provided with sealing rings 6 on both sides corresponding to the connection port 1c and the outlet 1b of the other cavity 1a, to ensure the sealing effect.

[0033] The drive unit 4 simultaneously drives the first rotating shaft 2a and the second rotating shaft 3a to switch between a first usage state and a second usage state. In the first usage state, the first cover plate 2 covers the outlet 1b of one cavity 1a, and the second cover plate 3 covers the connecting opening 1c of the other cavity 1a. In the second usage state, the first cover plate 2 covers the connecting opening 1c of one cavity 1a, and the second cover plate 3 covers the outlet 1b of the other cavity 1a. In both the first and second usage states, the first cover plate 2 and the second cover plate 3 are always maintained at a 90° angle.

[0034] In this embodiment, one end of the first rotating shaft 2a extends out of the body 1, and a driven gear 4d is installed on the extended part; one end of the second rotating shaft 3a also extends out of the body 1, and a driven gear 4d is also installed on the extended part. The two driven gears 4d are of the same specification and are on the same plane, but they are independent of each other and do not interfere with each other.

[0035] The drive unit 4 includes a drive motor 4a, a drive gear 4b, and two spur racks 4c. The output end of the drive motor 4a is connected to the drive gear 4b; the drive gear 4b meshes with the spur teeth on one side of the two spur racks 4c; the spur teeth on the other side of the two spur racks 4c simultaneously mesh with two driven gears 4d.

[0036] Furthermore, it also includes a fixing frame 5, which is fixed to the outer surface of the main body 1, and the drive motor 4a is fixed to the fixing frame 5.

[0037] Furthermore, the outer surface of the body 1 is also provided with a groove 1e, and the middle part of the straight toothed racks 4c on both sides is provided with a protrusion corresponding to the groove 1e along the length direction, and the protrusion is engaged on the groove 1e.

[0038] The drive motor 4a drives the drive gear 4b to rotate, and the drive gear 4b drives the two spur racks 4c on both sides to slide back and forth in the length direction. The two spur racks 4c on both sides drive the two driven gears 4d to rotate synchronously, thereby realizing the switching between the first cover plate 2 and the second cover plate 3 in the first use state and the second use state.

[0039] Example 2

[0040] This embodiment is basically the same as Embodiment 1, except that it does not have a drive gear 4b, the two spur racks 4c are replaced with a single-sided spur rack, and a cylinder is installed. The output end of the cylinder is connected to one end of the single-sided spur rack, which simultaneously meshes with two driven gears 4d. By pulling the single-sided spur rack back and forth with the cylinder, the two driven gears 4d are driven to rotate.

[0041] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit the scope of protection of this utility model. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this utility model without departing from the essence and scope of the technical solutions of this utility model.
