Description

Technical Field

[0001] The present invention relates to the technical field of pressure vessels, and particularly to an explosion-proof steel cylinder with an intelligent early warning and monitoring function. Background Art

[0002] In a gas fire extinguishing system, a large number of explosion-proof steel cylinders are usually used to store high-pressure inert gases. For a gas fire extinguishing system, the explosion of a steel cylinder is one of the most dangerous safety accidents. If a single steel cylinder explodes, it may trigger a chain reaction, causing huge losses to life and property. The explosion of an explosion-proof steel cylinder is usually due to the quality problem of the steel cylinder. At the place where the wall thickness of the steel cylinder is relatively thin, the pressure will continuously accumulate due to the stress concentration phenomenon. During long-term use, this place will gradually bulge and deform outward, and finally crack and explode. Therefore, an early warning detection system is needed to timely detect and alarm the signs before the explosion of the explosion-proof steel cylinder.

[0003] In the existing related technologies, usually, wires are wound around the outer side of the steel cylinder. When the steel cylinder deforms, the wires will be broken, so that the receiver cannot receive the electrical signal, thereby realizing the detection function. This structure has high requirements for the material and installation of the wires. First, the wires need to have good hardness (to prevent the wires from being broken during installation), and also need to have low ductility (to ensure that the wires will be broken once the steel cylinder deforms). And during installation, it is necessary to ensure that the wires are tightly attached to the side of the steel cylinder, and the wires cannot become loose at all during subsequent use. To meet the above special material and special installation requirements, the existing early warning detection system is inconvenient to install and has a high cost. Summary of the Invention

[0019] Further, in each connector, a relief groove is also arranged on the rotating shaft, and the relief groove penetrates through the first segment and the second segment.

[0022] Further, in each connector, let the length of the long groove be l, the length of the wide groove be w, the distances from the two joint holes to the nearest end face of the connector be a and b respectively, and the depths of the two joint holes be both h, then the wire length S satisfies: l + 2w + a + b + h ≤ S ≤ l + 2w + a + b + 2h.

[0023] Further, in each connector, a placement hole is arranged on the fitting surface, and a magnet is arranged in the placement hole.

[0045] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installation", "connection", and "connection" should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0046] The present invention relates to an explosion-proof steel cylinder with an intelligent early warning and monitoring function, as Figures 1-2 shown, including:

[0047] A cylinder body 1, which stores high-pressure gas inside and has a cylindrical outer side surface;

[0048] A monitoring component, which is sleeved on the outer side surface of the cylinder body 1; the number of monitoring components can be set according to the usage requirements and is sleeved on the outer side surface of the cylinder body 1 at equal intervals along the axial direction of the cylinder body 1;

[0049] A detector, which has a working indicator light, a fault indicator light, an alarm indicator light, etc., can be installed on the outer surface of the fire steel cylinder on-site, is connected to the monitoring component, and can be used to send an electrical signal to the monitoring component and receive the electrical signal transmitted back by the monitoring component.

[0050] The overall working principle of this explosion-proof steel cylinder is as follows: as Figure 1 shown, when the cylinder body 1 does not deform, the monitoring component can conduct the electrical signal, so the electrical signal emitted from the detector can be transmitted through the monitoring component itself and then received by the detector; once the cylinder body 1 deforms, at this time the monitoring component will deform along with the deformation of the cylinder body 1, and the deformed monitoring component can no longer conduct the electrical signal, so the detector can no longer receive the electrical signal, thereby identifying the deformation of the cylinder body 1. In a system composed of multiple explosion-proof steel cylinders, the detector can also supplement the address information of each cylinder body 1 and upload it to the total monitor. Before the physical explosion of the steel cylinder body, the detector can sense the plastic deformation occurring in its local area, send out an alarm signal, prompt the staff to check and handle, and prevent the explosion from occurring.

[0051] The overall monitoring component can be sleeved on the cylinder body 1 horizontally or with a certain inclination, and its structure is as Figures 3-4 shown. Each monitoring component includes a plurality of connectors 2 distributed circumferentially along the cylinder body 1, and an elastic ring 3 sleeved on the outer side surfaces of all the connectors 2.

[0052] In addition to its own arc-shaped main body structure, each connector 2 is also provided with other special structures, as Figures 5-8 shown, including:

[0053] A waist-shaped groove 21, which is arranged at one end of the connector 2, and the arc axes at both ends of the waist-shaped groove 21 are parallel to the axis of the cylinder body 1;

[0054] A rotating shaft 22, which is arranged at the other end of the connector 2, and the axis of the rotating shaft 22 is parallel to the axis of the cylinder body 1;

[0055] A fitting surface 23, which is in a curved surface shape, is arranged on the side of the connector 2 facing the cylinder body 1, and the radius of the fitting surface 23 is equal to the radius of the outer side surface of the cylinder body 1;

[0056] The installation groove 24 is provided on the connector 2 and extends to both ends of the connector 2; at one end of the connector 2, the installation groove 24 is located between the waist-shaped groove 21 and the fitting surface 23; at the other end of the connector 2, the installation groove 24 is located between the rotating shaft 22 and the fitting surface 23;

[0057] The wire 25 is arranged in the installation groove 24;

[0058] In the monitoring assembly, the rotating shaft 22 of each connector 2 extends into the waist-shaped groove 21 of an adjacent connector 2, and the two wires 25 of two adjacent connectors 2 are attached to each other at the opposite ends of the two connectors 2. For example, if all the connectors 2 are numbered in sequence as A, B, C..., the rotating shaft 22 of the A connector 2 will extend into the waist-shaped groove 21 of the B connector 2, the rotating shaft 22 of the B connector 2 will extend into the waist-shaped groove 21 of the C connector 2, and the wire 25 of the B connector 2 will be attached to the wire 25 of the A connector 2 and the wire 25 of the C connector 2 at its two ends respectively. Whether the monitoring assembly is horizontally or inclinedly sleeved on the bottle body 1, the above structural form needs to be adopted. In the horizontal case, the shapes of all the connectors 2 can be kept the same; while in the inclined case, the shapes of the fitting surfaces 23 of each connector 2 may be slightly different, so labels need to be added on the connector 2 to distinguish its position.

[0059] The specific working process and principle of the monitoring assembly are as follows:

[0060] Connect multiple connectors 2 into a ring and then sleeve it on the bottle body 1, and then put on the elastic ring 3. When the bottle body 1 is not deformed, as Figure 10 shown, the fitting surface 23 will stick to the outer side of the bottle body 1. Under the action of the elastic ring 3, the distance between multiple connectors 2 will be tightened to the minimum value, so that the wires 25 on each connector 2 are attached to each other and remain in the attached state under the action of the elastic ring 3, so that the current can conduct between multiple connectors 2.

[0061] When the bottle body 1 is deformed, as Figure 11 shown, the deformed part will push the corresponding connector 2 outwards. At this time, since the two connectors 2 are connected by the cooperation of the rotating shaft 22 and the waist-shaped groove 21, one end of the connector 2 at this place will rotate, causing the wire 25 at the other end to separate from the wires 25 of other connectors 2. And due to the setting of the waist-shaped groove 21, the connector 2 will move away from another connector 2 during the rotation process, further increasing the separation distance between the wires 25, so that the current can no longer conduct between the two connectors 2, thus realizing the feedback of the deformation of the bottle body 1.

[0062] It can be seen that the structure of the monitoring component is more concise, the connector 2 in the monitoring component has the same structure, and can be manufactured by the mold injection molding process, so the production cost is lower. At the same time, the monitoring component can remove the stringent requirements on the wire material in the prior art, and the function of the monitoring component can be realized by using any material wire on the market, which further saves the production cost. At the same time, the monitoring component only needs to simply insert the wire 25 into the installation groove 24, the rotating shaft 22 into the waist groove 21 and the elastic ring 3 to complete the entire assembly and installation work, eliminating the stringent requirements for installation due to the special wire material in the prior art. In addition, the monitoring component will not destroy its own structure during the entire working process, so it can also be reused, further saving costs.

[0063] In each connector 2, process holes can be opened on the side of the connector 2. These process holes make the thickness of various parts of the connector 2 as consistent as possible. In this way, during injection molding, the shrinkage of various parts of the connector 2 will be consistent during the cooling process, thereby ensuring the dimensional accuracy of various structures on the connector 2, especially the waist groove 21 and the installation groove 24, and ensuring that the wires 25 can be accurately fitted and separated.

[0064] It is preferred that the distance between the end of the waist groove 21 away from the rotation shaft 22 and the fitting surface 23 is smaller than the distance between the end of the waist groove 21 close to the rotation shaft 22 and the fitting surface 23, so that the waist groove 21 as a whole presents a certain tilt shape in the connector 2. Under this structure, when the connector 2 rotates, it can not only guide the two end faces of the connector 2 to separate quickly from each other, but also make the two wires 25 located on the end faces have a certain misalignment in the radial direction of the bottle body 1, thereby further ensuring the separation effect of the wires 25.

[0065] During the use of the monitoring assembly, it is necessary to keep the adjacent connectors 2 from moving in the axial direction of the bottle body 1. Therefore, it is preferred that in each connector 2, the waist-shaped groove 21 includes a first groove body 21a and a second groove body 21b, and the cross section of the first groove body 21a is smaller than the cross section of the second groove body 21b; the rotating shaft 22 includes a first segment 22a and a second segment 22b, and the second segment 22b is located at the end of the rotating shaft 22 away from the connector 2, and the diameter of the first segment 22a is smaller than the second segment 22b;

[0066] In the monitoring assembly, the first segment 22a of each connector 2 extends into the first groove 21a of an adjacent connector 2, and the second segment 22b of each connector 2 extends into the second groove 21b of an adjacent connector 2, so that the end face of the second segment 22b will abut against the outer contour of the first groove 21a, so that the first groove 21a can be clamped between the adjacent connector 2 and its second segment 22b, thereby limiting the movement between the adjacent connectors 2 in the axial direction of the bottle body 1.

[0067] Under the above structure, the installation of the rotating shaft 22 may require methods such as screw fixation and glue bonding for installation. To further eliminate these steps, in each connector 2 of this detection assembly, a relief groove 22c is preferably provided on the rotating shaft 22. The relief groove 22c penetrates through the first segment 22a and the second segment 22b, so that the first segment 22a and the second segment 22b can generate inward elastic deformation, so that the diameter of the second segment 22b can be reduced through deformation during installation, so as to pass through the first groove body 21a, and when it reaches the second groove body 21b, it resumes to complete the snap-in installation. In this way, the entire rotating shaft 22 can be injection-molded with the connector 2 as a whole, further simplifying the structure and improving the assembly efficiency. The second segment 22b is preferably arranged in a shape with a gradually decreasing diameter along the direction away from the first segment 22a, which can further facilitate the second segment 22b to pass through the first groove body 21a.

[0068] If the installation groove 24 is simply designed as a groove opened along the length direction of the connector 2, after the wire 25 is installed in the installation groove 24, it will form a form where both ends of the wire 25 are at both ends of the connector 2. Then, the form of the point contact where the end faces of the adjacent two wires 25 are in contact with each other will be formed. This not only has high requirements for the cut-off part of the wire 25 (i.e., the end face of the wire 25), but also has poor contact reliability. Therefore, this monitoring assembly has a special design for the installation groove 24. In each connector 2, the installation groove 24 includes a long groove 24a and two wide grooves 24b; the long groove 24a is arranged on the side of the connector 2 and extends along the length direction of the connector 2; the two wide grooves 24b are respectively arranged at the ends of the connector and extend along the width direction of the connector 2; when the wire 25 is installed, as Figure 9 shown, it will become a form extending along the width direction of the connector 2 at the end of the connector 2. Then, the form of the line contact where the sides of the adjacent two wires 25 are in contact with each other will be formed. This not only increases the contact reliability, but also no longer has harsh requirements for the processing of the cut-off part of the wire 25.

[0069] Preferably, in each connector 2, the cross-sectional profile of the wide groove 24b is preferably set as an arc with a radian greater than 180° and less than 360°, that is, the cross-section of the wide groove 24b presents a shape greater than 1 / 2 circle and less than a whole circle. The diameter of the wide groove 24b is the same as the diameter of the wire 25. As Figure 11 shown, under this structure, the wire 25 can be stuck in the wide groove 24b, and only a part of it extends out of the wide groove 24b for contact with another wire 25, so as to ensure the stability of the wire 25 fixed at the end of the connector 2.

[0070] Preferably, in each connector 2, two long slots 24a are provided and are respectively arranged on opposite sides of the connector 2; two connector holes 24c are arranged in any one of the long slots 24a. Then when the wire 25 is installed, the two ends of the wire 25 can be inserted into the connector holes 24c in the form shown in Figure 9 , so that the whole wire 25 can be stably fixed on the connector 2.

[0071] In each connector 2, let the length of the long slot 24a be l, the length of the wide slot 24b be w, the distances from the two connector holes 24c to the end face of the nearest connector 2 be a and b respectively, and the depths of the two connector holes 24c be h. Then preferably, the length S of the wire 25 is set to: l + 2w + a + b + h ≤ S ≤ l + 2w + a + b + 2h. Then during installation, both ends of the wire 25 can extend at least into the connector holes 24c deeper than the midpoint, so as to ensure that the wire 25 will not fall off.

[0072] If the connector 2 is directly sleeved on the outer side of the bottle body 1 without any fixation, it may slide down after long-term use, and finally multiple monitoring components will stack together, affecting the accuracy of the whole-bottle monitoring; while gluing it on the outer side of the bottle body 1 will affect the rotation ability of the connector 2. Therefore, this monitoring component adopts the form of magnetic fixation. In each connector 2, a placement hole 26 is provided on the fitting surface 23, and a magnet is arranged in the placement hole 26. In this way, the fixation of the connector 2 on the outer side of the bottle body 1 can be ensured. When the bottle body 1 is deformed, the protrusion of the bottle body 1 can also push the connector 2 to rotate, and under the adsorption of the magnet, the connector 2 can still maintain the fixation in the height direction.

[0073] Preferably, in each connector 2, two placement holes 26 are provided and are respectively arranged at both ends of the connector 2. In this way, when the bottle body 1 is deformed, since both ends of the connector 2 will adsorb the bottle body 1, both ends of the connector 2 will fit with the bottle body 1 as much as possible. And since only one kidney-shaped slot 21 is provided on one connector 2, even if the convex point of the bottle body 1 just lies at the center of the connector 2, the connector 2 can quickly turn into a rotational angle form, so that the two wires 25 can be quickly separated. The inclined setting of the kidney-shaped slot 21 cooperates with the two magnets, which can further accelerate the separation speed of the two wires 25.

[0074] Preferably, in each connector 2, an extension block 27 is further provided on the side of the connector 2 away from the bottle body 1, and a groove is provided on the extension block 27, and the elastic ring 3 extends into the groove. In this way, the contact point between the elastic ring 3 and the connector 2 can be on the outer side of the kidney-shaped slot 21, so as to prevent the elastic ring 3 from affecting the rotation of the connector 2.

[0075] Preferably, in each connector 2, two extension blocks 27 are provided and are respectively arranged at both ends of the connector 2. In this structure, when the bottle body 1 is not deformed, as Figure 10 shown, since the connector 2 is completely fitted to the bottle body 1, the force F applied by the elastic ring 3 to the connector 2 will be along the radial direction of the bottle body 1, ensuring the fitting tightness between the connector 2 and the bottle body 1; when the bottle body 1 is deformed, as Figure 11 shown, since the connector 2 rotates, it will drive the elastic ring 3 to no longer be a perfect circle but form a shape protruding outward at the rotating connector 2. At this time, the force F applied by the elastic ring 3 to the connector 2 is not along the radial direction of the bottle body 1 but will be more inwardly offset relative to the radial direction of the bottle body 1. In this stress state, the connector 2 will be more likely to have a rotational tendency, so the separation effect of the wire 25 at the rotation center can be further improved. Baffles extending to the two extension blocks 27 at both ends are provided on both sides of the connector 2 to prevent the elastic ring 3 from falling off the connector 2.

[0076] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will have various changes and improvements, and these changes and improvements all fall within the scope of the present invention claimed.
