Description

Technical Field

[0001] This utility model relates to the field of chemical equipment technology, specifically to a spherical three-in-one machine signal line external protection and flexible busbar device. Background Technology

[0002] The spherical three-in-one multi-functional machine refers to a multi-functional machine that can continuously complete three functions: material filtration, washing, and drying. The three-in-one sphere is equipped with temperature and pressure detection points and valve actuators. The signal lines of these detection points and valve actuators need to be collected in the PLC control cabinet. Traditionally, the signal collection is done by laying a stainless steel tube on the inner surface of the sphere as a protective tube for the signal lines, and then collecting all the signal lines to one outlet, where a flexible metal tube is used to lead the signal lines to the cabinet.

[0003] However, the above wiring method has its shortcomings in use: because the signal line is inside the sphere, although it looks better on the outside, the sphere needs to be rotated at different angles during the production process to correspond to the clean drying position, the filtration washing position and the door opening position. As a result, the wires and signal lines inside the sphere will often break or wear due to rotation. Moreover, since the signal line and wires are inside, maintenance is very time-consuming.

[0004] Therefore, this utility model provides an external protection and flexible busbar device for the signal line of a spherical three-in-one machine. Utility Model Content

[0005] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an external protection and flexible busbar device for the signal lines of a spherical three-in-one machine, so as to solve the problems mentioned in the background technology. This utility model has the function of laying the signal lines and wires on the outside of the sphere and protecting them, and at the same time, it has the function of making it easier to disassemble and assemble the signal lines and wires, thus making it easier to inspect and repair the signal lines and wires.

[0006] To achieve the above objectives, this utility model is implemented through the following technical solution: a spherical three-in-one signal line external protection and flexible busbar device, comprising a sphere, an adapter tube provided at the bottom of the sphere, a plurality of rigid conduits distributed at equal angles surrounding the outer periphery of the adapter tube, one side of the rigid conduit being fixedly connected to the outer wall of the sphere via a positioning tube, one end of the adapter tube being detachably connected to a busbar, a wire passage notch with a width smaller than the inner diameter of the rigid conduit being provided on the side wall of the rigid conduit away from the outer wall of the sphere, a plurality of connecting shafts distributed along the length direction passing through the rigid conduit, the connecting shafts and the rigid conduit being rotatably and slidably engaged, one end of the connecting shaft passing through the wire passage notch and a hook plate being fixedly sleeved on it, the hook plate being able to enter and exit the wire passage notch.

[0007] Furthermore, a row of guide sleeves is fixedly connected to the side of the rigid conduit opposite to the outer wall of the sphere. The guide sleeves and the connecting shaft are in clearance fit, and a baffle is welded to the other end of the connecting shaft.

[0008] Furthermore, the hook plate has an arc-shaped structure with its inner arc surface facing the outer wall of the sphere. A positioning hole fixedly sleeved on the connecting shaft is provided in the middle of the hook plate. The thickness of the hook plate is less than the width of the wire-passing notch and its length is greater than the width of the wire-passing notch.

[0009] Furthermore, a support spring is sleeved on the connecting shaft between the baffle and the guide sleeve.

[0010] Furthermore, a hook ring is welded to one end of the connecting shaft.

[0011] Furthermore, one end of the wire notch extends to the end of the rigid conduit away from the adapter, and a C-shaped clamping tube is fixedly connected to the outer periphery of the adapter. The clamping tube and the rigid conduit are clamped together, and the inner cavity of the clamping tube and the adapter are connected, with the notch on it facing the outer wall of the sphere.

[0012] Furthermore, a swivel sleeve is fitted onto one end of the manifold hose, and the swivel sleeve and one end of the adapter tube are screwed together.

[0013] Furthermore, it also includes a positioning ring, which is housed inside the adapter tube and located near the bottom. The outer wall of the positioning ring is fixedly connected to a drive shaft that penetrates the wall of the adapter tube. The drive shaft is rotatably connected to the adapter tube and is fitted with a nut located outside the adapter tube. The nut is screwed into the drive shaft.

[0014] The beneficial effects of this utility model are as follows:

[0015] 1. In this utility model, several rigid conduits are fixed around the outside of the sphere and distributed around the adapter tube. Signal lines in all directions on the sphere are located in each rigid conduit and then converge in the adapter tube. This makes the signal line wiring neater. The rigid conduits can protect the signal lines. A busbar is detachably connected to one end of the adapter tube. The busbar guides the converged signal lines into the PLC control cabinet. The busbar can reduce the torque on the signal lines and wires caused by the rotation of the sphere, thereby extending the life of the signal lines and reducing the difficulty of later maintenance of the signal lines and wires.

[0016] 2. In this utility model, a wire passage notch is opened on the outer wall of the rigid conduit. The function of the wire passage notch is to facilitate the signal line to pass through the rigid conduit. One end of the adapter and the manifold are detachably connected, which makes it easier for the signal line and wire to pass through the rigid conduit to pass into the manifold. This has the advantages of making the laying, wiring and subsequent maintenance operations more convenient.

[0017] 3. In this utility model, a hook plate is provided at the wire passage gap, which can enter and exit the wire passage gap. The hook plate is connected to the rigid conduit through a connecting shaft. The hook plate, in conjunction with the rotation and sliding function of the connecting shaft, allows the hook plate to enter the rigid conduit through the wire passage gap, which can prevent the signal and wire from falling out of the wire passage gap. This has the advantage of making the signal line and wire wiring more secure. Attached Figure Description

[0024] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0025] Please see Figures 1 to 5 This utility model provides a technical solution: a spherical three-in-one machine signal line external protection and flexible bus device, including a sphere 1. The outer wall of the sphere 1 is equipped with electrical appliances such as a temperature transmitter, a pressure transmitter and a valve actuator. In use, the above electrical appliances are installed on the outer wall of the sphere 1. The above electrical appliances all include corresponding signal lines and wires. The temperature transmitter and pressure transmitter are usually fixedly installed on the outer wall of the sphere 1 by flange pipes and bolts.

[0026] In this technical solution, a transfer tube 2 is provided at the bottom of the outer part of the sphere 1. The transfer tube 2 is located at the lower part of the sphere 1 and is offset from the discharge tube at the bottom of the sphere 1. Several rigid conduits 3 are arranged at equal angles around the outer periphery of the transfer tube 2. The number of rigid conduits 3 is the same as the number of electrical appliances. The rigid conduits 3 can be stainless steel pipes. One side of the rigid conduits 3 is fixedly connected to the outer wall of the sphere 1 through a positioning tube. During manufacturing, the rigid conduits 3 have an arc-shaped structure. During use, the signal wires and wires of each electrical appliance are inserted from one end of the rigid conduit 3 and then exited from the transfer tube 2. The rigid conduits 3 make the laying of signal wires and wires neater and can also protect the signal wires and wires.

[0027] One end of the adapter tube 2 is detachably connected to a manifold hose 4. Preferably, one end of the manifold hose 4 is fitted with a rotating sleeve 41. Specifically, one end of the manifold hose 4 is fixedly connected to a rigid tube, which is fitted onto the bottom of the rotating sleeve 41 and the two are rotatably connected. The rotating sleeve 41 and one end of the adapter tube 2 are screwed together. Since the sphere 1 rotates at a certain angle multiple times a day, the manifold hose 4 not only protects the signal lines and wires but also compensates for displacement. The manifold hose 4 is made of PU tubing, which has better flexibility, thus reducing the torque on the signal lines and wires caused by the rotation of the sphere 1, thereby extending the lifespan of the signal lines and wires. Furthermore, since the signal lines and wires are located outside the sphere 1, compared to the traditional structure that embeds the signal lines and wires inside the sphere 1, this design reduces the difficulty of later maintenance of the signal lines and wires.

[0028] Furthermore, a wire-passing notch 31 with a width smaller than the inner diameter of the rigid conduit 3 is provided on the side wall of the rigid conduit 3 facing away from the outer wall of the sphere 1. Since the signal wire and conductor are soft, they are easy to bend when passing through the free end of the rigid conduit 3, which makes the laying difficult. The wire-passing notch 31 can assist the signal wire and conductor in passing through and reduce the difficulty of laying the line. Among them, several connecting shafts 5 are arranged along the length of the rigid conduit 3. The connecting shafts 5 and the rigid conduit 3 are in rotational and sliding engagement. One end of the connecting shaft 5 passes through the wire-passing notch 31 and a hook plate 6 is fixedly sleeved on it. The hook plate 6 can enter and exit the wire-passing notch 31. The function of the hook plate 6 is to prevent the line inside the rigid conduit 3 from falling out of the wire-passing notch 31. Simply put, by using the rotation and sliding function of the connecting shaft 5, the hook plate 6 can enter the rigid conduit 3 and rest inside the rigid conduit 3, thereby preventing the line from falling out of the wire-passing notch 31.

[0029] Specifically, a row of guide sleeves 32 is fixedly connected to the side of the rigid conduit 3 opposite to the outer wall of the sphere 1. The guide sleeves 32 and the connecting shaft 5 are in clearance fit. A baffle 51 is welded to the other end of the connecting shaft 5. The hook plate 6 can be controlled to enter and exit the rigid conduit 3 by rotating and sliding the connecting shaft 5.

[0030] In this embodiment, the hook plate 6 has an arc-shaped structure and its inner arc surface is opposite to the outer wall of the sphere 1. The hook plate 6 has a positioning hole in the middle that is fixedly sleeved on the connecting shaft 5. The thickness of the hook plate 6 is less than the width of the wire passage notch 31 and its length is greater than the width of the wire passage notch 31. After the hook plate 6 enters the rigid conduit 3, the lines on both sides of the connecting shaft 5 will be blocked and limited by the hook plate 6.

[0031] Furthermore, a support spring 7 is fitted onto the connecting shaft 5 between the baffle 51 and the guide sleeve 32. The support spring 7 can apply an elastic thrust to the connecting shaft 5 via the baffle 51, causing it to move in the direction of the ball 1. This allows the hook plate 6 to press the wiring inside the rigid conduit 3, effectively preventing the wiring inside the rigid conduit 3 from loosening. A hook ring 52 is welded to one end of the connecting shaft 5. The hook ring 52 is a handheld component, facilitating manual control of the rotation and sliding of the connecting shaft 5.

[0032] In this embodiment, one end of the wire-passing notch 31 extends to the end of the rigid conduit 3 away from the adapter tube 2. This arrangement can further reduce the difficulty of wire threading. That is, when threading, the wire can be placed into the rigid conduit 3 through the wire-passing notch 31. A C-shaped clamping tube 21 is fixedly connected to the outer periphery of the adapter tube 2. The clamping tube 21 is a PVC pipe. The clamping tube 21 and the rigid conduit 3 are clamped together. Specifically, it is clamped together with the rigid conduit 3 through the notch on it. This arrangement can reduce the difficulty of connecting the rigid conduit 3 and the adapter tube 2. The inner cavity of the clamping tube 21 and the adapter tube 2 are connected and the notch on it faces the outer wall of the sphere 1. Thus, by pulling the adapter tube 2, it can be simultaneously connected and separated from several rigid conduits 3.

[0033] In this embodiment, a positioning ring 8 is also included. The positioning ring 8 is housed within the adapter tube 2 and located near the bottom. In use, the wire passes through the positioning ring 8. A drive shaft 9, penetrating the wall of the adapter tube 2, is fixedly connected to the outer wall of the positioning ring 8. The drive shaft 9 and the adapter tube 2 are rotatably connected, and a nut 101 is fitted onto the drive shaft 9 outside the adapter tube 2. A handle is welded to the free end of the drive shaft 9, serving as a handheld component. When the drive shaft 9 rotates, it drives the positioning ring 8 to rotate, thereby bending the wire passing through the positioning ring 8 into an approximately Z-shaped structure. This arrangement keeps the wire inside the adapter tube 2 in a fixed state, preventing wire wear. The nut 101 and the drive shaft 9 are screwed together. When the nut 101 is tightened, it presses against the adapter tube 2, thereby locking the drive shaft 9 using friction.

[0034] Working principle: When laying the wiring, the principle of laying as close as possible is adopted. The wiring of each appliance is connected to the adjacent rigid conduit 3. Specifically, the wiring of the appliance adjacent to the free end of each rigid conduit 3 is inserted through the wire passage notch 31. When inserting, the connecting shaft 5 is manually rotated by the hook ring 52 and then pulled outward, so that the hook plate 6 moves out of the rigid conduit 3. At this time, the support spring 7 is compressed by the retaining plate 51. Then the wiring is placed inside the hook plate 6, and the current connecting shaft 5 is reset. The support spring 7 will extend, and the hook plate 6 enters the rigid conduit 3. Then the connection is twisted 90 degrees. Connect shaft 5 and release it. At this time, hook plate 6 will squeeze the line onto the inner wall of rigid conduit 3. Repeat the above operation on adjacent connecting shafts 5 in this way. This cycle can realize the laying of the line in rigid conduit 3. Pass one end of the line through the other end of rigid conduit 3, and then pass each line into adapter pipe 2 and manifold 4. Then, connect adapter pipe 2 to the other end of each rigid conduit 3 through the various clamping pipes 21 on it. At this time, the laying of all lines is completed. Finally, connect the line led out from manifold 4 to PLC control cabinet.

[0035] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
