Description

Technical Field

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

[0002] In gas fire extinguishing systems, a large number of explosion-proof cylinders are usually used to store high-pressure inert gases. For gas fire extinguishing systems, cylinder explosion is one of the most dangerous safety accidents. If a single cylinder explodes, it may trigger a chain reaction, causing huge losses to life and property. The explosion of explosion-proof cylinders is usually due to quality problems of the cylinders. The thinner wall of the cylinder will continue to accumulate pressure due to stress concentration. During long-term use, this part will gradually bulge outward and deform, and eventually crack and explode. Therefore, an early warning detection system is needed to detect and alarm the signs of explosion of explosion-proof cylinders in a timely manner.

[0003] In the existing related technologies, the detection function is usually achieved by wrapping a wire around the outside of the cylinder. When the cylinder is deformed, the wire will be broken, making it impossible for the receiver to receive the electrical signal. This structure has very high requirements for the material and installation of the wire. First, the wire must have good hardness (to prevent the wire from being torn off during installation), and the wire must have low ductility (to ensure that the wire will be broken once the cylinder is deformed). During installation, it is necessary to ensure that the wire fits tightly to the side of the cylinder, and the wire cannot be loose during subsequent use. In order to meet the above-mentioned special material and special installation requirements, the existing early warning detection system is inconvenient to install and has high costs. Summary of the invention

[0004] The invention provides an explosion-proof steel cylinder with intelligent early warning monitoring function, which can effectively solve the problems of inconvenient installation and high cost of existing explosion-proof steel cylinders with early warning monitoring function.

[0007] Furthermore, in each connector, a clearance groove is also arranged on the rotating shaft, and the clearance groove runs through the first segment and the second segment.

[0008] Furthermore, in each connector, the mounting groove includes a long groove and two wide grooves; the long groove is arranged on the side of the connector and extends along the length direction of the connector; the two wide grooves are respectively arranged at the ends of the connector and extend along the width direction of the connector.

[0009] Furthermore, in each connector, two long slots are provided, and are respectively provided on two opposite sides of the connector; and two connector holes are provided in one long slot.

[0010] Furthermore, in each connector, let the length of the long slot be l, the length of the wide slot be w, the distances between the two connector holes and the nearest connector end face be a and b respectively, and the depths of the two connector holes be h, then the wire length S satisfies: l+2w+a+b+h≤S≤l+2w+a+b+2h.

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0019] In the description of the present invention, it should be noted that the orientations or positional relationships indicated by “center”, “up”, “down”, “left”, “right”, “vertical”, “horizontal”, “inside” and “outside”, etc., are based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the referred device or element must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0020] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" 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, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0021] The present invention relates to an explosion-proof steel cylinder with intelligent early warning monitoring function, such as Figure 1~2 As shown, including: The bottle body 1 stores high-pressure gas inside and has a cylindrical outer surface; The monitoring components are sleeved on the outer side of the bottle body 1; the number of the monitoring components can be set according to the use requirements, and the monitoring components are sleeved on the outer side of the bottle body 1 at equal intervals along the axial direction of the bottle body 1; The detector has a working indicator light, a fault indicator light, an alarm indicator light, etc. It can be installed on the outer surface of the fire cylinder on site and connected to the monitoring component. It can be used to send electrical signals to the monitoring component and receive electrical signals sent back by the monitoring component.

[0022] The overall working principle of this explosion-proof cylinder is as follows: Figure 1As shown, when the bottle body 1 is not deformed, the monitoring component can conduct electrical signals, so the electrical signals sent from the detector can be transmitted by the monitoring component itself and then received by the detector; once the bottle body 1 is deformed, the monitoring component will deform along with the deformation of the bottle body 1. The deformed monitoring component can no longer conduct electrical signals, so the electrical signals can no longer be received from the detector, thereby identifying the deformation of the bottle body 1. In a system composed of multiple explosion-proof cylinders, the detector can also supplement the address information of each bottle body 1 and upload it to the main monitor. Before the physical explosion of the cylinder body, the detector can sense the local plastic deformation and send out an alarm signal to prompt the staff to conduct inspections and prevent explosions.

[0023] The monitoring assembly as a whole can be placed on the bottle body 1 horizontally or with a certain inclination. Figure 3~4 As shown, each monitoring assembly includes a plurality of connectors 2 distributed along the circumference of the bottle body 1 , and an elastic ring 3 sleeved on the outer sides of all the connectors 2 .

[0024] In addition to the arc-shaped main structure, each connector 2 is also provided with other special structures, such as Figures 5 to 8 As shown, including: The waist-shaped groove 21 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 bottle body 1; The rotating shaft 22 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 bottle body 1; The fitting surface 23 is in a curved shape and is disposed on the side of the connector 2 facing the bottle body 1, and the radius of the fitting surface 23 is equal to the radius of the outer side surface of the bottle body 1; The mounting 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 mounting groove 24 is located between the waist-shaped groove 21 and the fitting surface 23; at the other end of the connector 2, the mounting groove 24 is located between the rotating shaft 22 and the fitting surface 23; The wire 25 is arranged in the mounting groove 24; In the monitoring assembly, the 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 fit together at the opposite ends of the two connectors 2. For example, if all connectors 2 are numbered in the order of A, B, C, etc., the shaft 22 of connector 2 No. A will extend into the waist-shaped groove 21 of connector 2 No. B, the shaft 22 of connector 2 No. B will extend into the waist-shaped groove 21 of connector 2 No. C, and the wire 25 of connector 2 No. B will fit together with the wire 25 of connector 2 No. A and the wire 25 of connector 2 No. C at both ends thereof. Regardless of whether the monitoring assembly as a whole is horizontally or tiltedly mounted on the bottle body 1, the above-mentioned structural form needs to be adopted. In the horizontal state, the shapes of all connectors 2 can be kept consistent; in the tilted state, the shapes of the fitting surfaces 23 of each connector 2 may be slightly different, so it is necessary to add numbers to the connectors 2 to distinguish their positions.

[0025] The specific working process and principle of the monitoring component are as follows: Connect multiple connectors 2 into a ring and put them on the bottle body 1, and then put on the elastic ring 3. When the bottle body 1 is not deformed, Fig.10 As shown, the fitting surface 23 will fit the outer side of the bottle body 1, and the spacing between the multiple connectors 2 will be tightened to the minimum value under the action of the elastic ring 3, so that the wires 25 on each connector 2 fit each other and remain in the fitting state under the action of the elastic ring 3, so that current can be conducted between the multiple connectors 2.

[0026] When the bottle body 1 is deformed, Fig.11 As shown, the deformed portion will push the connector 2 at the corresponding position outward. At this time, since the two connectors 2 are connected by the rotating shaft 22 and the waist-shaped groove 21, one end of the connector 2 at this position will rotate, so that the wire 25 at the other end is separated from the wire 25 of the other connector 2, and due to the setting of the waist-shaped groove 21, the connector 2 will move away from the other connector 2 during the rotation process, thereby further increasing the separation distance between the wires 25, so that the current can no longer be conducted between the two connectors 2, thereby realizing the feedback of the deformation of the bottle body 1.

[0027] 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.

[0028] 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.

[0029] 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.

[0030] 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; 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.

[0031] Under the above structure, the installation of the rotating shaft 22 may need to be fixed with screws, glued, etc. In order to further save these steps, the detection component is preferably provided with a clearance groove 22c on the rotating shaft 22 in each connector 2, and the clearance groove 22c runs through the first segment 22a and the second segment 22b, so that the first segment 22a and the second segment 22b can produce an inward elastic deformation, so that the second segment 22b can reduce its diameter through deformation during installation, thereby passing through the first slot body 21a, and recovering to complete the snap-in installation when reaching the second slot body 21b. In this way, the rotating shaft 22 as a whole can be injection molded into one piece with the connector 2, further simplifying the structure and improving assembly efficiency. The second segment 22b is preferably configured to have a shape in which the diameter gradually decreases in the direction away from the first segment 22a, which can further facilitate the second segment 22b to pass through the first slot body 21a.

[0032] If the installation slot 24 is simply designed as a slot body opened along the length direction of the connector 2, then after the wire 25 is installed in the installation slot 24, it will form a form in which the two ends of the wire 25 are at the two ends of the connector 2, and the two adjacent wires 25 will be in a point contact form where the end faces of the wire 25 fit together. Not only is the requirement for the cut point of the wire 25 (i.e., the end face of the wire 25) very high, but the contact reliability is also poor. Therefore, the monitoring component has a special design for the installation slot 24. In each connector 2, the installation slot 24 includes a long slot 24a and two wide slots 24b; the long slot 24a is arranged on the side of the connector 2 and extends along the length direction of the connector 2; the two wide slots 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, Fig. 9 As shown, at the end of the connector 2, it will become a form extending along the width direction of the connector 2, so that the two adjacent wires 25 will become a line contact form in which the sides of the wires 25 are attached to the sides of the wires 25, which not only increases the reliability of the contact, but also no longer has strict requirements on the processing of the cut part of the wires 25.

[0033] Preferably, in each connector 2, the cross-sectional profile of the wide groove 24b is preferably set to an arc with an arc greater than 180° and less than 360°, that is, the cross-sectional profile of the wide groove 24b is greater than 1 / 2 circle and less than the full circle, and the diameter of the wide groove 24b is the same as the diameter of the wire 25. Fig.11 As 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 to contact another wire 25, thereby ensuring the stability of the wire 25 fixed at the end of the connector 2.

[0034] Preferably, two long slots 24a are provided in each connector 2, and are respectively provided on opposite sides of the connector 2; and two connector holes 24c are provided in any long slot 24a. Then, when the wire 25 is installed, it can be as follows Fig. 9 In the form shown, both ends of the wire 25 are inserted into the connector hole 24c, so that the wire 25 as a whole can be stably fixed on the connector 2.

[0035] In each connector 2, the length of the long slot 24a is l, the length of the wide slot 24b is w, the distances between the two connector holes 24c and the nearest end face of the connector 2 are a and b respectively, and the depths of the two connector holes 24c are both h. It is preferred to set the length S of the wire 25 to: l+2w+a+b+h≤S≤l+2w+a+b+2h. During installation, both ends of the wire 25 can at least extend into the connector hole 24c deeper than the midpoint, thereby ensuring that the wire 25 will not fall off.

[0036] If the connector 2 is directly put on the outer side of the bottle body 1 without any fixation, it may slide down after long-term use, and eventually multiple monitoring components will be stacked together, affecting the accuracy of monitoring the entire bottle; and if it is glued to the outer side of the bottle body 1, it will affect the rotation ability of the connector 2. Therefore, the 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 provided in the placement hole 26. This can ensure that the connector 2 is fixed on the outer side of the bottle body 1. 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 effect of the magnet, the connector 2 can still maintain the fixation in the height direction.

[0037] Preferably, two placement holes 26 are provided in each connector 2, and are respectively provided at both ends of the connector 2, so that when the bottle body 1 is deformed, both ends of the connector 2 will adsorb the bottle body 1, so both ends of the connector 2 will fit the bottle body 1 as much as possible, and since only one waist-shaped groove 21 is provided on one connector 2, even if the protruding point of the bottle body 1 is just located at the center of the connector 2, the connector 2 can be quickly turned into a rotation angle, so that the two wires 25 can be quickly separated. The inclined setting of the waist-shaped groove 21 cooperates with the two magnets to further speed up the separation speed of the two wires 25.

[0038] Preferably, in each connector 2, an extension block 27 is 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, so that the contact point between the elastic ring 3 and the connector 2 can be further outside the waist-shaped groove 21, thereby preventing the elastic ring 3 from affecting the rotation of the connector 2.

[0039] Preferably, two extension blocks 27 are provided in each connector 2, and are respectively provided at both ends of the connector 2. Under this structure, when the bottle body 1 is not deformed, as shown in FIG. Fig.10 As shown, since the connector 2 is completely fitted with the bottle body 1, the force F exerted by the elastic ring 3 on the connector 2 will be along the radial direction of the bottle body 1, ensuring the tightness of the fit between the connector 2 and the bottle body 1; and when the bottle body 1 is deformed, such as Fig.11 As shown, since the connector 2 rotates, the elastic ring 3 is no longer a perfect circle, but forms an outward convex shape at the rotating connector 2. At this time, the force F exerted by the elastic ring 3 on the connector 2 is not along the radial direction of the bottle body 1, but becomes more inwardly offset relative to the radial direction of the bottle body 1. Under this force state, the connector 2 is more likely to have a rotation tendency, so the separation effect of the wire 25 at the rotation center can be further improved. Both sides of the connector 2 are provided with baffles extending to the two extension blocks 27 at both ends to prevent the elastic ring 3 from falling off the connector 2.

[0040] The above shows and describes the basic principles, main features and advantages of the present invention. It should be understood by those skilled in the art that the present invention is not limited to the above embodiments. The above embodiments and descriptions are only for explaining the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention may have various changes and improvements, which fall within the scope of the present invention to be protected.
