Description

Technical Field

[0001] This utility model relates to a wiring protection device, and more particularly to a protection device for wiring fire signal valves, belonging to the field of fire signal valve wiring technology. Background Technology

[0002] Fire signal gate valves are devices used in fire protection systems. In addition to the advantages of resilient seated gate valves, they can also visually display the valve's opening degree, allowing for timely assessment from a distance and prompt action. Their rapid and reliable opening and closing make them commonly used in fire protection systems. Fire signal butterfly valves typically have three wires: a common wire, a wire for when the valve is open, and a wire for when the valve is closed. A multimeter can be used to test which two wires are continuous when the valve is closed. When wiring, connect the common wire to one input terminal of the input module and the wire for when the valve is open to the other input terminal.

[0003] When wiring fire signal valves, three connecting wires are usually wrapped in a metal flexible conduit for protection. However, this method has the following problems: the three wires are all inside the metal flexible conduit and are easy to get tangled together, affecting the reliability of the wiring. If the electrical tape is loose, the wires can easily get tangled together, causing a short circuit and posing a danger. Fire signal butterfly valves will experience shaking during installation, which can easily cause the wiring to loosen or even break, affecting the fire alarm system's monitoring and control of the signal valve.

[0004] To solve the above-mentioned technical problems, a protective device for wiring fire signal valves is proposed. Utility Model Content

[0005] In view of this, the present invention provides a protective device for wiring fire signal valves to solve or alleviate the technical problems existing in the prior art, and at least provides a beneficial option.

[0006] The technical solution of this utility model is as follows: a protective device for wiring fire signal valves, including a protective box and a fixing plate;

[0007] The protective box includes a lower box and an upper box arranged symmetrically. Three semi-circular tubes are fixedly connected to both sides of the lower box and the upper box. An anti-slip pad is fixedly connected to one side of the inside of each semi-circular tube. Two limiting rods are fixedly connected to one side of the inside of the lower box. An insulating sleeve is fitted on one side of each limiting rod, and the insulating sleeve is fixedly connected to the limiting rod.

[0008] The fixed plate includes a disc and a connecting plate. The connecting plate is symmetrically fixedly connected to one side of the disc. The disc is fixedly connected to the lower box body. Two fixing holes are opened inside the connecting plate.

[0009] More preferably, a transparent plate is fixedly connected to one side of the upper box.

[0010] More preferably, the disk has screw holes evenly distributed on one side, and mounting holes are provided inside the disk.

[0011] More preferably, the lower box body is internally fixedly connected to four connecting rods, and the upper box body is internally fixedly connected to four connecting sleeves. One end of each connecting sleeve engages with a connecting rod, and a fixing screw is internally threaded into each connecting sleeve. One end of each fixing screw is threaded into a connecting rod.

[0012] More preferably, a limiting plate is provided on one side of the interior of the lower box, and the limiting rod passes through the limiting plate and is fixedly connected to the limiting plate.

[0013] More preferably, a fixing plate is symmetrically provided on one side of the limiting plate, a limiting block is fixedly connected to the top of the fixing plate, and two insertion holes are opened on both sides of the limiting plate.

[0015] The present invention has the following advantages due to the adoption of the above technical solution:

[0016] I. This utility model covers the wiring connection section between the input module and the signal valve by setting up a lower box and an upper box. The three wires are covered by three sets of two symmetrically arranged semicircular tubes. The anti-slip pads in the semicircular tubes fix the wires. After the connection section of the wires is wrapped with insulating tape, the limiting rod and insulating sleeve separate the three wires, making them independent and preventing them from tangling with each other, thus ensuring the reliability of the wiring. The semicircular tubes and anti-slip pads increase the resistance to the movement of the wires inside the upper and lower boxes, preventing the wires from being pulled and causing the connection to break.

[0017] Second, this utility model connects the protection box and the signal valve by setting a disc with screw holes and mounting holes, and sets a connecting plate and fixing holes on the disc to facilitate the installation of the input module on one side of the disc, providing installation space for the input module and preventing the wiring from being pulled due to the shaking of the input module.

[0025] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this invention. Therefore, the drawings and description are considered exemplary in nature and not restrictive.

[0026] The embodiments of this utility model will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1-4 As shown, this utility model embodiment provides a protective device for wiring fire signal valves, which consists of a protective box 10 and a fixing plate 20.

[0028] The protective box 10 includes a lower box body 11 and an upper box body 31 arranged symmetrically. The lower box body 11 and the upper box body 31 are the same size. Three semi-circular tubes 12 are fixedly connected to both sides of the lower box body 11 and the upper box body 31. When the upper box body 31 is connected to the lower box body 11, the semi-circular tubes 12 form a group of three sets of circular sleeve structures. An anti-slip pad 13 is fixedly connected to one side of the inner side of the semi-circular tube 12. One side of the anti-slip pad 13 is arc-shaped and contacts the wiring, so that the anti-slip pad 13 fits the wiring better. Two limiting rods 18 are fixedly connected to one side of the inner side of the lower box body 11. The distance between the two limiting rods 18 is greater than the diameter of the wiring. An insulating sleeve 17 is sleeved on one side of the limiting rod 18. The top of the insulating sleeve 17 is integrally formed with a tapered edge 37, which makes it easy to insert the wiring between the two limiting rods 18. The insulating sleeve 17 is fixedly connected to the limiting rods 18. The three wirings in the protective box 10 are separated by the limiting rods 18 and the insulating sleeve 17.

[0029] In one embodiment, in order to facilitate the connection and fixation of the lower box 11 and the upper box 31, four connecting rods 14 are fixedly connected inside the lower box 11, and four connecting sleeves 33 are fixedly connected inside the upper box 31. One end of the connecting sleeve 33 is engaged with the connecting rod 14, and a fixing screw 32 is threaded inside the connecting sleeve 33. One end of the fixing screw 32 is threadedly connected to the connecting rod 14.

[0030] In one embodiment, a transparent plate 34 is fixedly connected to one side of the upper housing 31 to facilitate observation of the wiring status.

[0031] In one embodiment, to prevent the wiring from moving excessively and not contacting the insulating sleeve 17, a limiting plate 15 is provided on one side of the lower housing 11. A limiting rod 18 passes through the limiting plate 15 and is fixedly connected to the limiting plate 15. The limiting plate 15 limits the movable range of the wiring. A fixing plate 16 is symmetrically provided on one side of the limiting plate 15. A limiting block 19 is fixedly connected to the top of the fixing plate 16. The limiting block 19 prevents the wiring located on both sides from shaking. Both the limiting block 19 and the insulating sleeve 17 are made of flexible insulating rubber. Two insertion holes 35 are opened on both sides of the limiting plate 15. An insertion rod 36 is inserted into the insertion hole 35. One end of the insertion rod 36 is fixedly connected to the fixing plate 16. The plane area of ​​the fixing plate 16 is larger than that of the limiting block 19. When the limiting block 19 is pulled out, the wiring can be moved out together through the fixing plate 16, which facilitates the removal of the wiring.

[0032] The fixed plate 20 includes a disc 21 and a connecting plate 24. The connecting plate 24 is symmetrically fixedly connected to one side of the disc 21. The disc 21 is fixedly connected to the lower box 11. Two fixing holes 25 are opened inside the connecting plate 24. The input module can be fixed on the disc 21 by using the fixing holes 25 and the connecting plate 24. Screw holes 22 are evenly distributed on one side of the disc 21. The distribution position of the screw holes 22 corresponds to the position of the connecting bolt of the signal valve. The mounting hole 23 is opened inside the disc 21 and matches the signal valve.

[0033] In operation, this invention involves aligning the disc 21 with the signal valve and connecting and fixing the disc 21 to the signal valve using connecting bolts and screw holes 22. The input module for monitoring the signal valve is placed between two connecting plates 24 and connected and fixed to the connecting plates 24 using screws and other components and fixing holes 25. The upper housing 31 is separated from the lower housing 11. The three wires of the signal valve are placed into the three semi-circular tubes 12 of the lower housing 11, and the three wires of the input module are placed into the three semi-circular tubes 12 on the other side. The wires of the input module are connected to the wires of the signal valve, and insulating tape is wrapped around the connection section so that the connection section is located in the lower housing 11. The connection is then pressed down. The wire is moved to contact the insulating sleeve 17. The wires on both sides contact the insulating sleeve 17 and the limiting block 19 respectively. The wire in the middle is located between the two insulating sleeves 17, separating the three wires. The upper box 31 and the lower box 11 are assembled, and the connecting sleeve 33 is inserted into the connecting rod 14. At this time, the semi-circular tube 12 of the upper box 31 and the semi-circular tube 12 of the lower box 11 are assembled to form a circular sleeve structure. The wire is located between the two semi-circular tubes 12 and contacts the anti-slip pad 13. The fixing screw 32 is inserted into the connecting sleeve 33 to connect and fix the upper box 31 and the lower box 11. The state of the wire connection in the upper box 31 and the lower box 11 can be observed through the transparent plate 34.

[0034] The above description is merely a specific embodiment of this utility model, but the protection scope of this utility model is not limited thereto. Any person skilled in the art can easily conceive of various variations or substitutions within the technical scope disclosed in this utility model, and these should all be included within the protection scope of this utility model. Therefore, the protection scope of this utility model should be determined by the protection scope of the claims.
