Description

Technical Field

[0001] The present invention relates to the technical field of safety equipment devices in coal mines, and particularly relates to a mine-used automatic explosion-proof water bag shed device and a using method thereof. Background Technique

[0002] The shock waves and flames generated by gas (coal dust) explosions in coal mines can cause serious equipment damage, property losses and casualties, and are the number one killer of underground safety production. A large number of scholars have developed explosion suppression and isolation technologies for controlling explosion flames. According to relevant technical principles, at present, China's gas (coal dust) explosion suppression and isolation technologies can be divided into active explosion suppression and isolation technologies and passive explosion suppression and isolation technologies. Among them, the explosion-proof water bags in passive explosion suppression and isolation technologies have been widely used in coal mines due to their advantages such as low cost and simple installation.

[0003] Currently, the depth of coal mining in China is gradually increasing, and it is gradually transforming towards large-scale, large-scale, intelligent and digital. The requirements for safety are higher than ever. Most traditional explosion-proof water bags adopt a decoupling installation method, and this installation method often requires the shock wave pressure generated by the explosion to reach a certain threshold (usually 5-9 kp). At the same time, the decoupling installation method has certain requirements from a safety perspective. If the installation is improper, when a gas (coal dust) explosion occurs in a coal mine, it is difficult for the explosion-proof water bag to decouple, which reduces the reliability of the explosion-proof water bag and brings danger to underground production operations. This is an urgent problem to be solved at present. Summary of the Invention

[0004] The technical problem to be solved by the present invention is: an automatic chain detachment device with high reliability is used to replace the traditional decoupling installation method of explosion-proof water bags, so as to improve the reliability of the explosion-proof water bags, so that when a gas (coal dust) explosion occurs in a coal mine, the explosion-proof water bags can quickly act and respond, sprinkle inhibitors to form an inhibition zone in a certain area, and inhibit and block the explosion flames generated by the explosion, so as to achieve the purpose of reducing equipment damage, casualties and property losses.

[0005] To solve the above problems, the present invention provides the following technical solutions:

[0007] Preferably, the transmission assembly includes a rotating rod; the middle of the rotating rod is hingedly installed at the middle position of the inner cavity of the housing, and connecting rods serving as the input end and the output end are respectively hingedly installed on the upper and lower sides of the rotating rod; the connecting rod located in the upper part is connected to the bearing plate.

[0008] Furthermore, springs are also arranged at the positions where the rotating rod is hinged to the two connecting rods; the other ends of the springs are installed in the inner cavity of the housing; when the springs are in the natural state, the included angle between the rotating rod and the two connecting rods is 90°.

[0009] Furthermore, limiting ropes respectively connected to the two connecting rods are also arranged on the rotating rod; when the limiting ropes are straightened, the included angle between the rotating rod and the two connecting rods is 90°.

[0010] Preferably, an adjusting nut for adjusting the lateral distance between the adjusting water bags is arranged on the support rod.

[0011] Preferably, the size and shape of the output end of the transmission assembly are the same as the shape of the notch on the chain, and the notch on the chain is a one-way locking structure, and the chain can only slide past the output end of the transmission assembly in a bottom-up manner for movement.

[0012] Preferably, the housing and the chain box are detachably connected through a connecting piece.

[0013] The present invention also discloses a using method of a mine-used automatic explosion-proof water bag shed device, including the following steps:

[0014] S1. Install the housing on the explosion-proof water bag shed through the support rod, and make the end with the bearing plate face outward and the other end face the chain box for arrangement;

[0015] S2. After the installation is completed, fill water into each water bag, and hang the water bags on the explosion-proof water bag shed through the chain and the chain box;

[0016] S3. When a gas or coal dust explosion occurs underground, after the bearing plate receives the shock wave generated by the explosion, through the pressurization of the upper connecting rod, the rotation drive of the rotating rod drives the inward contraction of the lower connecting rod, so that the connecting rod serving as the output end is separated from the chain at the connection, realizing chain disconnection. After the chain disconnection, the water bags fall off, and a suppression zone is quickly formed in the designated area;

[0017] S4. After the chain disconnection action is completed, the connecting rod rebounds under the action of the spring; after the chain is reinstalled, the chain disconnection device can be reused.

[0018] The beneficial effects of the present invention:

[0019] The present invention replaces the traditional decoupling installation method by adopting an automatic chain - disengaging device. When there is no explosion in the coal mine underground, the automatic chain - disengaging device is in a waiting - response state at this time; when an explosion occurs in the coal mine underground, the automatic chain - disengaging device quickly acts in response to achieve chain disengagement, so that the water in the explosion - proof water bags is dispersed, forming an inhibition zone in a certain area. By using this device, when a gas (coal dust) explosion occurs in the coal mine underground, the reliability of the explosion - proof water bags can be greatly improved, and a good inhibitory effect on the explosion situation can be achieved.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0025] The present invention will be further introduced below in conjunction with the drawings and specific embodiments:

[0028] The transmission assembly includes a rotating rod 6; the middle part of the rotating rod 6 is hinged and installed at the middle position of the inner cavity of the housing 12, and connecting rods 5 serving as the input end and the output end are respectively hinged and installed on the upper and lower sides of the rotating rod 6; the connecting rod 5 located in the upper part is connected to the bearing plate 3.

[0029] Springs 7 are also arranged at the positions where the rotating rod 6 is hinged to the two connecting rods 5; the other ends of the springs 7 are installed in the inner cavity of the housing 12; when the springs are in the natural state, the included angle between the rotating rod 6 and the two connecting rods 5 is 90°. In this embodiment, when the springs in the lower part of the inner cavity of the housing 12 are fully contracted, the pressure received by the bearing plate is much smaller than the pressure required for the traditional decoupling device to act.

[0030] Limit ropes 11 respectively connected to the two connecting rods 5 are also arranged on the rotating rod 6; when the limit ropes 11 are straightened, the included angle between the rotating rod 6 and the two connecting rods 5 is 90°. The limit ropes 11 are used to prevent the excessive movement angle between the connecting rods 5 and the rotating rod.

[0031] Adjusting nuts 2 for adjusting the horizontal distance between the water bags are arranged on the support rod 1. At the same time, different-sized brackets can be adapted for cooperative installation through the adjusting nuts.

[0032] The size and shape of the output end of the transmission assembly are the same as the shape of the notch on the chain 8, and the notch on the chain 8 is a one-way locking structure, and the chain 8 can only slide past the output end of the transmission assembly in the bottom-up manner for movement. The chain 8 with the locking function and the output end connecting rod can form a self-locking structure to prevent the chain 8 from loosening downward automatically and unable to maintain the normal state of the water bags.

When a gas or coal dust explosion occurs underground, after the bearing plate 3 is subjected to the shock wave generated by the explosion, through the pressurization of the upper connecting rod 5 and the rotational drive of the rotating rod 6, the lower connecting rod 5 is driven to retract, causing the connecting rod and the chain at the connection as the output end to separate, achieving chain detachment. After the chain detachment, the water bag falls off, and a suppression zone is quickly formed in the designated area;

[0038] S4. After the chain detachment action is completed, the connecting rod rebounds under the action of the spring 7; after the chain 9 is reinstalled, the chain detachment device can be reused.
