Description

Technical Field

[0001] This utility model belongs to the field of automatic valve control technology, and particularly relates to the automatic control of valves in mining extraction pipelines, specifically a pipeline conduction status regulation device. Background Technology

[0002] There are a large number of mechanical valves installed on the underground gas extraction pipelines in coal mines. Currently, they mainly rely on manual adjustment. Due to the large number of borehole extraction pipelines, the manual labor intensity is high and the adjustment frequency is low. When abnormal problems such as gas leakage or blockage are detected in the boreholes, it is impossible to adjust in time and to reasonably distribute the negative pressure of each borehole extraction.

[0003] Replacing mechanical valves with explosion-proof electric valves for mining can achieve automation, but if they are installed and used in large quantities, the wiring and debugging along the extraction pipeline are more complicated, and there is also a greater risk of explosion failure and safety hazards. Later maintenance is inconvenient, and the price of explosion-proof electrical equipment for mining is generally higher, resulting in higher system costs. In addition, the valves need to be frequently started and stopped to adjust the angle, and the frequent starting of the internal motor of the explosion-proof electric valve for mining can easily cause damage.

[0004] If mechanical valves are replaced with pneumatic valves, although the problems of the aforementioned explosion-proof electric valves for mining are not present, pneumatic valves generally only have two states: fully closed or fully shut, and their opening angle is generally difficult to control accurately from a remote perspective.

[0005] To address the aforementioned issues, there is an urgent need for a pipeline continuity control device to enable remote automatic control of the continuity status of underground gas extraction pipelines in coal mines. This device should be easy to install and maintain, highly safe, low-cost, and suitable for widespread application. Utility Model Content

Detailed Implementation

[0021] To make the technical problems solved, the technical solutions, and the beneficial effects of this utility model clearer, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present utility model and are not intended to limit the present utility model.

[0022] Combination Figures 1 to 4 As shown in the figure, the borehole extraction pipeline conduction state switching device provided in this embodiment of the utility model mainly includes a valve body 1, a swing cylinder 2, and a ratchet mechanism 3.

[0023] The valve body 1 is mainly composed of a valve core 101 and a valve shaft 102. The valve shaft 102 can drive the valve core 101 to rotate, thereby switching the conduction state of the valve body 1. As a preferred embodiment, the valve body 1 is a butterfly valve and the valve core 101 is a valve plate structure.

[0024] The swing cylinder 2 mainly consists of a swing cylinder output shaft 201, a pneumatic interface 202, and a fixed frame 203. As a preferred embodiment, the swing cylinder 2 is an existing pneumatic swing cylinder, which can be pneumatically controlled to rotate clockwise and counterclockwise at a fixed angle.

[0025] The ratchet mechanism 3 mainly consists of an outer ring 301 and an inner ring 302. As a preferred embodiment, the ratchet mechanism 3 also includes a rotation direction switching key 303 and a rotation direction switching swing cylinder 304. As a preferred embodiment, the ratchet mechanism 3 is a ratchet wrench mechanism (existing technology). The outer ring 301 can only drive the inner ring 302 to rotate in one direction, either clockwise or counterclockwise, and the rotation direction can be switched by swinging the rotation direction switching key 303.

[0026] The swing cylinder output shaft 201 of the swing cylinder 2 is fixedly connected to the outer ring 301 of the ratchet mechanism 3, and the inner ring 302 of the ratchet mechanism 3 is fixedly connected to the valve shaft 102 of the valve body 1; the swing cylinder 2 is fixed to the valve body 1 by a fixing bracket 203.

[0027] The rotation direction switching cylinder 304 mainly consists of a rotation direction switching cylinder output shaft 3041 and a rotation direction switching cylinder pneumatic interface 3042. The rotation direction switching cylinder 304 is fixed to the valve body 1 by a fixing bracket 203, and the rotation direction switching cylinder output shaft 3041 is fixedly connected to the rotation direction switching key 303.

[0028] As a preferred embodiment, the inner ring 302 of the ratchet mechanism 3 is connected to the valve shaft 102 of the valve body 1 via a reducer 4.

[0029] The working principle of this utility model pipeline conduction state control device is as follows: By controlling the output shaft 201 of the swing cylinder 2, the outer ring 301 of the ratchet mechanism 3 is driven to rotate reciprocally in both clockwise and counterclockwise directions, thereby driving the inner ring 302 of the ratchet mechanism 3 to rotate in one direction (clockwise or counterclockwise) (since the outer ring 301 of the ratchet mechanism 3 can only drive the inner ring 302 to rotate in one direction), and then the valve core 101 is driven to rotate in one direction (clockwise or counterclockwise) through the valve shaft 102 of the valve body 1. When it is necessary to switch the rotation direction of the valve core 101, the output shaft 3041 of the swing cylinder 304 can be controlled to drive the rotation direction switching key 303 of the ratchet mechanism 3 to rotate, thereby switching the rotation direction of the inner ring 302 of the ratchet mechanism 3, and thus switching the rotation direction of the valve core 101.

[0030] In addition, utilizing the pipeline continuity control device of this utility model, a method for controlling pipeline continuity is provided, specifically including the following steps: S1: Set the reciprocating rotation angle of the swing cylinder 2 to f, and control the swing cylinder output shaft 201 of the swing cylinder 2 to reciprocate clockwise and counterclockwise n times through the air circuit, and then drive the valve core 101 to rotate by an angle n×f through the ratchet mechanism 3 in a clockwise or counterclockwise direction; S2: When it is necessary to rotate in the opposite direction, the rotation direction switching cylinder 304 is controlled by the air circuit to drive the rotation direction switching key 303 to swing, thereby switching the rotation direction of the ratchet mechanism 3 to the opposite direction; the output shaft 201 of the swing cylinder 2 is controlled by the air circuit to rotate clockwise and counterclockwise m times, thereby driving the valve core 101 to rotate in the opposite direction by an angle m×f. S3: Repeating S1 and S2 will allow the valve core 101 to rotate by an angle (nm) f, thereby enabling multi-angle control of the conduction state of valve 1 and its connecting pipeline.

[0031] It is understood that the above specific description of this utility model is only used to illustrate this utility model and is not limited to the technical solutions described in the embodiments of this utility model. Those skilled in the art should understand that modifications or equivalent substitutions can still be made to this utility model to achieve the same technical effect; as long as the use needs are met, they are all within the protection scope of this utility model.
