Description

Technical Field

[0001] The utility model relates to the technical field of fire-fighting equipment, in particular to a fixing mechanism and a fire extinguishing starting device. Background Art

[0002] A gas fire extinguishing system refers to a fire extinguishing system in which the fire extinguishing agent is usually stored in a pressure vessel in a liquid, liquefied gas or gas state, and is ejected in a gas (including steam, aerosol) state as a fire extinguishing medium during fire extinguishing. A gas fire extinguishing system generally consists of a fire extinguishing agent storage device, a starting and distributing device, a conveying and releasing device, a monitoring device, etc. A pipe network type gas fire extinguishing system has three starting methods: automatic control, manual control and mechanical emergency operation. Among them, mechanical emergency operation is generally to manually open the selection valve of the corresponding protection area when the automatic control and manual control fail, and then press the mechanical emergency starting handle on the electromagnetic driving component of the driving gas cylinder group corresponding to the protection area to open the driving gas cylinder group, and the driving gas opens the corresponding fire extinguishing agent cylinder group to achieve the fire extinguishing method.

[0003] The existing electromagnetic driving components of driving gas cylinder groups are generally inserted with two safety pins up and down to prevent accidental touch. During mechanical emergency operation, the two safety pins need to be pulled out first before the mechanical emergency starting handle can be pressed. The tail ends of the safety pins have anti-detachment ropes or anti-detachment steel balls, and both ends of the anti-detachment ropes are in metal weights.

[0004] During mechanical emergency operation, due to the existence of the anti-detachment rope or anti-detachment steel ball, a relatively large pulling force is required to pull out the safety pin. Especially when the anti-detachment rope or anti-detachment steel ball is stuck due to dust or rust, it is more difficult to pull out, which is not conducive to quick start-up. In addition, the anti-detachment rope or anti-detachment steel ball provides soft positioning for the safety pin, that is, the safety pin can be pulled out under a certain pulling force, and the anti-accidental touch effect is insufficient. In addition, the driving gas cylinder group is fixed on the chassis through a clamp, and each gas cylinder corresponds to a clamp, which needs to be installed and fixed one by one, and the disassembly and assembly are time-consuming and laborious.

[0030] To make the above objects, features and advantages of the present utility model more obvious and understandable, the following will give a detailed description of the specific implementation manners of the present utility model with reference to the accompanying drawings of the specification.

[0031] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the connotation of the present utility model. Therefore, the present utility model is not limited by the specific embodiments disclosed below.

[0032] Secondly, the so-called "one embodiment" or "embodiment" herein refers to a specific feature, structure or characteristic that can be included in at least one implementation manner of the present utility model. The "in one embodiment" appearing in different places in this specification does not all refer to the same embodiment, nor is it an individual or alternative embodiment that is mutually exclusive with other embodiments.

[0033] Embodiment 1, referring to Figure 1-4 , which is the first embodiment of the present utility model. This embodiment provides a fixing mechanism, including a support component 100 and an anti-disengagement component 200 arranged on the support component 100;

[0034] The support component 100 includes an operation board 101, and the operation board 101 is arranged vertically;

[0035] The anti-disengagement component 200 includes a positioning assembly 201 arranged on the operation board 101. The positioning assembly 201 includes an operation disk 201a rotatably arranged on the operation board 101. An extrusion block 201b is integrally arranged on the operation disk 201a. Movable blocks 201c are abutted on both the upper and lower sides of the extrusion block 201b. A connecting rod 201d is arranged on one side of the movable block 201c away from the extrusion block 201b. A positioning board 201e is arranged on one side of the connecting rod 201d away from the movable block 201c.

[0036] When manually rotating the operation disk 201a, the extrusion block 201b rotates accordingly. The rotation of the extrusion block 201b squeezes the movable block 201c. The movable block 201c, the connecting rod 201d, the positioning plate 201e and the operation plate 101 are arranged in contact or not in contact with the operation plate 101. When the extrusion block 201b squeezes the movable block 201c, the movable block 201c, the connecting rod 201d and the positioning plate 201e move together.

[0037] Furthermore, the positioning assembly 201 further includes a fixed block 201f fixedly arranged on the operation plate 101. The fixed block 201f is sleeved outside the connecting rod 201d. A first spring 201g is arranged between the fixed block 201f and the movable block 201c, and the first spring 201g is sleeved outside the connecting rod 201d.

[0038] The fixed block 201f is fixed on the operation plate 101, and the connecting rod 201d slides through the inside of the fixed block 201f.

[0039] Furthermore, the extrusion block 201b and the operation disk 201a are coaxially arranged, and the extrusion block 201b is oval.

[0040] The extrusion block 201b and the operation disk 201a are coaxially and fixedly connected. Rotating the operation disk 201a drives the extrusion block 201b to rotate; the extrusion block 201b is oval. In the normal state, the short-axis side of the extrusion block 201b contacts the movable block 201c. During mechanical emergency operation, rotate the operation disk 201a, and the extrusion block 201b rotates with the operation disk 201a. As the extrusion block 201b rotates, it gradually squeezes the movable block 201c until the long-axis end of the extrusion block 201b contacts the movable block 201c, and the two positioning plates 201e in the upper and lower positions are both released from positioning.

[0041] The extrusion block 201b can also be a disk-shaped cam with a protruding part. When the protruding part of the disk-shaped cam squeezes the upper movable block 201c, the upper positioning plate 201e is released from positioning. When the protruding part of the disk-shaped cam squeezes the lower movable block 201c, the lower positioning plate 201e is released from positioning, which further improves the anti-misoperation effect, but there is one more rotation of the operation disk 201a in the operation.

[0042] Furthermore, the positioning assembly 201 further includes a through hole 201h arranged on the positioning plate 201e, and a first notch 201i is arranged on the side wall of the through hole 201h.

[0043] The through hole 201h is used for the first safety pin 404 or the second safety pin 405 to pass through.

[0044] Usage process: During normal use, the upper and lower positioning plates 201e are respectively stuck on the first safety pin 404 and the second safety pin 405. During mechanical emergency operation, manually rotate the operation disk 201a, the extrusion block 201b rotates with the operation disk 201a, gradually extrudes the movable block 201c, the movable block 201c drives the connecting rod 201d to move, so that the positioning plate 201e on the connecting rod 201d moves away from the operation disk 201a, and the positioning function of the positioning plate 201e is released. At this time, the first safety pin 404 and the second safety pin 405 can be easily pulled out.

[0045] The method of using positioning is adopted to replace the anti - detachment structure at the end of the safety pin. After the positioning is released, the safety pin can be easily pulled out, solving the problem of difficult extraction of the safety pin, which is beneficial to the rapid startup of the fire extinguishing system; due to the positioning function, it is very difficult to pull out the first safety pin 404 and the second safety pin 405 when they are accidentally subjected to external force, ensuring the anti - accidental touch effect.

[0046] Example 2, referring to Figure 1-4 , is the second embodiment of the present utility model. Different from the previous embodiment, the anti - detachment component 200 further includes a limit assembly 202 provided on the operation board 101. The limit assembly 202 includes a limit plate 202a provided on one side of the operation board 101. One side of the limit plate 202a is provided with a telescopic rod 202b. The end of the telescopic rod 202b away from the limit plate 202a is provided with a short plate 202c. The short plate 202c is fixed on the operation board 101. A second spring 202d is sleeved outside the telescopic rod 202b.

[0047] Furthermore, the support component 100 further includes a receiving groove 102 provided on the operation board 101, and the positioning component 201 is arranged in the receiving groove 102.

[0048] The side of the second bayonet 407 away from the operation board 101 is a vertical surface, which is used to cooperate with the limit plate 202a. In the direction of gradually approaching the operation board 101, the second bayonet 407 is an inclined surface that gradually becomes thicker, so that when the second safety pin 405 is inserted into the bottle valve 402, it squeezes the limit plate 202a, avoiding the limit assembly 202 from blocking the insertion of the second safety pin 405 into the bottle valve 402.

[0049] Usage process: In the prior art, there is a risk of loss of the safety pin after it is pulled out; in the present application, the first safety pin 404 is blocked by the block 408, so that the first safety pin 404 will not be pulled out from the operating panel 101 after being pulled out from the ejector pin 403, so that the first safety pin 404 is hung on the operating panel 101, thereby solving the problem of loss; for the second safety pin 405, as the second safety pin 405 is gradually pulled out, the tail end of the second safety pin 405 moves out of the bottle valve 402 and continues to move toward the operating panel 101. When the second bayonet 407 moves to the limit plate 202a, the second spring 202d squeezes the limit plate 202a and extends into the second bayonet 407, limiting the second safety pin 405 and restricting the second safety pin 405 from continuing to move, thereby preventing the second safety pin 405 from passing through the operating panel 101, and similarly making the second safety pin 405 hang on the operating panel 101, thereby solving the problem of loss.

[0050] Example 3, reference Figure 1-9 , which is the third embodiment of the utility model. Different from the previous embodiment, this embodiment provides a fire extinguishing starting device, including an upper fixing mechanism and a mounting component 300 arranged outside the operating panel 101, and a driving component 400 is arranged on the mounting component 300.

[0051] Furthermore, the driving component 400 includes a gas cylinder 401 arranged on the mounting component 300, and a bottle valve 402 is arranged at the outlet end of the gas cylinder 401, and a ejector pin 403 is arranged at the top of the bottle valve 402, and a first safety pin 404 is passed through the ejector pin 403, and a second safety pin 405 is passed through the bottle valve 402, and the first safety pin 404 and the second safety pin 405 both pass through the operating panel 101, and a first bayonet 406 is arranged on the first safety pin 404 and the second safety pin 405, and a second bayonet 407 is arranged at one end of the second safety pin 405 close to the bottle valve 402.

[0052] The driving component 400 includes a gas cylinder 401 for storing starting gas. There are multiple gas cylinders 401 and they are placed on the base frame 301. One side of the upper part of each gas cylinder 401 corresponds to an operating panel 101. The gas cylinder 401 is provided with a bottle valve 402 for controlling the opening of the gas cylinder 401. The bottle valve 402 is provided with a starting ejector pin 403. A first safety pin 404 is inserted on the ejector pin 403 and contacts the top surface of the bottle valve 402. A second safety pin 405 is inserted in the lower middle part of the bottle valve 402. The first safety pin 404 and the second safety pin 405 are both used to prevent the ejector pin 403 from being pressed down when accidentally touched. The first safety pin 404 and the second safety pin 405 are both rod-shaped with a pull ring at the head end, and one end of the first safety pin 404 and the second safety pin 405 with the pull ring is located at the operating panel 101. The tail ends of the first safety pin 404 and the second safety pin 405 are not provided with anti-slipping parts, anti-slipping ropes, and steel balls.

[0053] Further, the driving component 400 further includes a stop block 408 disposed on the first safety pin 404, and the stop block 408 is located between the ejector pin 403 and the bottle valve 402.

[0054] When the ejector pin 403 is extruded downward by an external force, it may cause the deformation of the first safety pin 404 and the second safety pin 405, thereby resulting in difficult extraction.

[0055] The whole stop block 408 is in a "U" shape and is fixedly connected to the first safety pin 404. In the normal state, the ejector pin 403 is located within the stop block 408. The lower end of the stop block 408 abuts against the top end of the bottle valve 402, and the upper end of the stop block 408 abuts against the upper end of the ejector pin 403. The stop block 408 blocks between the upper ends of the bottle valve 402 and the ejector pin 403, preventing the ejector pin 403 from moving downward under an external force. On the one hand, it further improves the anti-misoperation effect. On the other hand, when the ejector pin 403 is extruded by an external force, it presses against the stop block 408 instead of the first safety pin 404 and the second safety pin 405, avoiding the deformation of the first safety pin 404 and the second safety pin 405 due to the extrusion of the ejector pin 403. During mechanical emergency operation, when the first safety pin 404 is pulled out, the stop block 408 moves in the direction close to the operation panel 101 along with the first safety pin 404. When it moves out of the outside of the ejector pin 403, it loses the blocking effect, and the ejector pin 403 can be pressed downward.

[0056] Further, the installation component 300 includes a chassis 301 disposed outside the operation panel 101. A bottom plate 302 is arranged inside the chassis 301. The gas cylinder 401 is placed on the bottom plate 302. A first baffle 303 and a second baffle 304 are respectively arranged on both sides of the gas cylinder 401. The first baffle 303 is fixed on the chassis 301, and the second baffle 304 is hinged on the bottom plate 302. A second notch 305 adapted to the gas cylinder 401 is arranged on the second baffle 304. A positioning bolt 306 is arranged between the second baffle 304 and the chassis 301.

[0057] The gas cylinders 401 are placed side by side on the bottom plate 302. The gas cylinders 401 are limited by the second notch 305 on the second baffle 304 and the first baffle 303 to prevent the gas cylinders 401 from moving. The second baffle 304 is hinged on the bottom plate 302, and can simultaneously limit or release the limit of the gas cylinders 401, improving the convenience of installation and maintenance.
