Description

TECHNICAL FIELD

[0001] The utility model relates to a configuration device of fuse link, especially to a simple temperature-sensitive release device suitable for kitchen fire extinguishing system. BACKGROUND

[0002] For the current kitchen fire extinguishing system, its main triggering mode is through the fusing of fuse link (also called temperature-sensitive sheet), so that the temperature-sensitive shear sheet opens, thereby the steel wire rope connected is loosened. Through the release of the steel wire rope, the components such as gas valve connected on the steel wire rope are released.

[0003] However, the temperature-sensitive shear sheet needs to be adjusted to a suitable angle when being laid out, so that it can be smoothly fired when the fuse link fuses. If it is in the oil environment for a long time, the shaft or the upper end joint surface of the temperature-sensitive shear sheet is easy to be stuck due to the accumulation of oil, which causes the temperature-sensitive shear sheet to open slowly or fail, affecting the final firing of the fire extinguishing system.

[0004] At the same time, if the temperature-sensitive shear sheet is directly omitted, the positioning of the fuse link completely depends on the steel wire rope connected thereon, which may cause the fuse link to be excessively pulled by the steel wire rope during daily standby period, and may cause abnormal tearing, resulting in false triggering.

[0005] In addition, the current steel wire rope is only guided by a simple ring. During the release period, the steel wire rope is easy to be wound on the ring due to the stress pulling, which may also cause the final firing to fail.

[0006] In view of the above defects, the present design person actively researches and innovates to create a simple temperature-sensitive release device suitable for kitchen fire extinguishing system, so that it has more industrial utilization value. INVENTION CONTENTS

[0037] The specific embodiments of the utility model are described in further detail below in combination with the drawings and examples. The following examples are used to illustrate the utility model, but are not used to limit the scope of the utility model.

[0038] As Figs. 1-2 The simple temperature-sensitive release device suitable for kitchen fire extinguishing system, including the hoisting plate 1, its different lies in: the lower two ends of hoisting plate 1, both are provided with guide cylinder 2, for guiding the insertion of steel wire rope 4. Depending on the guidance of guide cylinder 2, steel wire rope 4 can smoothly slip off after the subsequent fuse link 3 is fused, and will not be wound on hoisting plate 1. At the same time, the lower center position of hoisting plate 1 is provided with a hoisting assembly, and the hoisting assembly is hung with fuse link 3. In this way, the stable load hanging of fuse link 3 can be realized, and there is no need to install temperature-sensitive shear blades for positioning. At the same time, the two ends of fuse link 3 are connected with steel wire rope 4, and steel wire rope 4 passes through guide cylinder 2. In this way, through the positioning of hoisting assembly, when fuse link 3 is in the state of balance point of daily standby, it does not need to rely on the pulling of steel wire rope 4, avoids its improper displacement, deviates from the direction of the cooking table, affects the final temperature-sensitive fusion, and also avoids abnormal tearing. Considering the need of fixed layout, a plurality of positioning nails 5 are arranged on hoisting plate 1. In this way, it can be positioned directly above the cooking table and fused when the cooking table has an abnormally high temperature. During implementation, in order to realize stable load positioning, the hoisting assembly used includes a mounting column 6 connected with hoisting plate 1, and the mounting column 6 is provided with a positioning assembly connected with fuse link 3. During implementation, for the need of some non-high-temperature pre-fusion, a fusion guide mechanism can be arranged on fuse link 3.

[0039] In combination with a preferred embodiment of the utility model, hoisting plate 1 includes a rectangular plate body, positioning nail 5 is connected into the plate body, and the edge of the plate body is provided with a circular arc chamfer. In this way, there will be no sharp part to avoid scratching workers during installation and debugging. At the same time, the plate body can be better attached and installed with indoor roof, lower edge of the range hood, etc.

[0040] Further, an adjusting pad 7 is arranged between guide cylinder 2 and hoisting plate 1, and guide cylinder 2, adjusting pad 7 and hoisting plate 1 are connected through mounting screw 16. In this way, the angle of guide cylinder 2 can be adjusted moderately for cooperation with the actual pulling direction of steel wire rope 4. And after adjustment, stable locking is realized. During implementation, the lower part of adjusting pad 7 is provided with a concave joint surface 8, and the upper end of the guide cylinder is in contact with the concave joint surface 8. In this way, better joint positioning can be realized.

[0041] In practical application, the fuse link 3 used in the present invention includes a link body, a hoisting hole 9 is provided at the upper end of the link body, and pulling holes 10 are provided at both ends of the link body. The hoisting hole 9 is connected to the positioning assembly, and the pulling holes 10 are connected to the corresponding steel wire rope 4. At the same time, to prevent tearing due to excessive local force at the contact point, contact retaining rings are embedded in the hoisting hole 9 and the pulling hole 10.

[0042] Furthermore, the front end of the steel wire rope 4 is equipped with a press-fit closure buckle 11. Furthermore, this buckle 11 is provided with a hook 12, which connects to the pull hole 10 of the fusible link 3. This facilitates on-site commissioning and eliminates the need to tie a knot at the front end of the steel wire rope 4. This prevents false triggering due to a loose knot, and also prevents damage to the pull hole 10 due to abnormal force caused by improper knotting.

[0043] To ensure proper steering adjustment of the fuse link 3, ensuring it is positioned within the path of the two steel cables 4 and prevents abnormal twisting and deformation, the mounting post 6 is connected to the mounting plate 1 via a pin 13, allowing the mounting post 6 to rotate freely relative to the mounting plate 1. Furthermore, the positioning component is a hook 14, enabling convenient and stable mounting.

[0044] During implementation, to meet certain requirements for premature melting at low temperatures, a fuse-guiding mechanism was employed consisting of several elliptical slots 15, spaced equidistantly from one another. This way, when the fuse link 3 undergoes local deformation due to heat, the elliptical slots 15 are the first to break due to the pull of the wire rope 4. Consequently, the stress maintaining the integrity of the fuse link 3 is less than the stress exerted by the wire rope 4, allowing it to tear without completely melting, thus loosening the wire rope 4.

[0045] It should be noted that during the implementation of this utility model, the material of the fuse link selected is a type that will not tear under the normal horizontal binding stress of the wire rope. This material is not the subject of protection of this utility model and will not be described in detail here. During implementation, users can also directly choose a commercially available tear-resistant fuse link.

[0046] The working principle of this utility model is as follows:

[0047] After the present invention is installed, the fuse link 3 will be subjected to the bearing stress brought by the positioning assembly and the steel wire rope 4 at the same time.

[0048] When the temperature applied by the stove exceeds the threshold, the lower part of the fuse link 3 is heated, and the elliptical slot 15 constituting the fuse guide mechanism is deformed abnormally, causing the fuse link 3 to melt from bottom to top. During this period, the fuse link 3 may be torn apart while melting, which does not affect the implementation of the utility model.

[0049] Then, the traction force on the steel wire rope 4 disappears, and the fire extinguishing device connected to the steel wire rope 4 is fired after the steel wire rope 4 is loosened, and the fire extinguishing is started.

[0050] It can be seen from the above description and the drawings that the utility model has the following advantages:

[0051] 1. The fuse link can be hung by the positioning assembly, and there is no need to set a temperature-sensitive shear piece, so that the corresponding firing operation can be performed after the steel wire rope is loosened, the use cost is reduced, and the on-site installation can be conveniently realized without winding layout of the temperature-sensitive shear piece.

[0052] 2. During standby, the fuse link can be balanced and lifted, and abnormal displacement does not occur, so that the temperature change of the cooking table can be effectively sensed.

[0053] 3. The steel wire rope is guided by the guide cylinder, and the lifting plate is not stuck or wound on the guide cylinder during release, so that the release can be smoothly realized.

[0054] 4. The fuse link is provided with a contact retaining ring, so that stable stress bearing can be realized without assembling the temperature-sensitive shear piece.

[0055] 5. The steel wire rope and the fuse link are hung in a non-knotting manner, so that accidental damage of the fuse link is avoided, and false triggering is avoided.

[0056] 6. The overall structure is simple, and the manufacturing and on-site debugging and installation are convenient, and there is no need to adjust the opening angle of the temperature-sensitive shear piece, so that the use is convenient.

[0057] In addition, the indicated direction or position relationship described in the utility model is based on the direction or position relationship shown in the drawings, and is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the indicated device or structure must have a specific direction or be operated in a specific direction, so it cannot be understood as a limitation on the utility model.

[0058] The above is only the preferred embodiment of the utility model, and is not used to limit the utility model, and it should be pointed out that for ordinary skilled persons in the technical field, without departing from the technical principle of the utility model, a number of improvements and modifications can be made, and these improvements and modifications should be regarded as the protection range of the utility model.
