Description

Technical Field

[0001] This utility model relates to the field of electromechanical engineering technology, specifically to a ventilation duct connection structure for coal mine electromechanical engineering. Background Technology

[0002] In coal mine electromechanical engineering, ventilation duct systems play a crucial role. They are responsible not only for air circulation and exchange within the mine but also directly affect the miners' working environment and safe production. However, traditional ventilation duct connection structures have many design shortcomings, particularly in terms of the flexibility and stability of connection methods, making it difficult to meet the demands of the complex and ever-changing mine environment.

[0003] Traditional ventilation duct connections mostly employ simple flange or welding methods. While these methods can meet basic connection requirements to some extent, they reveal numerous drawbacks in practical applications. For example, although flange connections are easy to disassemble and maintain, their sealing performance is often affected by factors such as bolt tightness and gasket aging, making them prone to leaks and thus affecting ventilation efficiency. While welding provides higher connection strength, once welded, it is difficult to disassemble and adjust, which is clearly inflexible for mines where frequent changes to the duct layout are required.

[0004] Furthermore, traditional ventilation duct connection structures are inadequate in dealing with the complex geological conditions and changing external environment within mines. For example, during mining operations, factors such as ground pressure and water damage can easily cause duct connections to loosen or deform, leading to poor ventilation or air leaks. In certain special environments, such as high-temperature, high-humidity, or corrosive gas environments, the durability and stability of traditional connection structures are also significantly reduced. Utility Model Content

[0005] The purpose of this utility model is to provide a connection structure for ventilation ducts in coal mine electromechanical engineering, in order to solve the problem mentioned in the background art that the current connection structure for ventilation ducts in coal mine electromechanical engineering requires flexible and rigid connections according to different usage conditions. When changing the connection method, the tools used need to be changed according to the different connection methods of the connectors, which is very inconvenient and affects the installation progress.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a ventilation duct connection structure for coal mine electromechanical engineering, comprising a first duct, a second duct, a connecting mechanism, and an auxiliary mechanism. The first duct and the second duct are connected by the connecting mechanism, which is disposed on the outer wall of the first duct and the second duct. The auxiliary mechanism is disposed on the outer wall of the connecting mechanism and is used to change the soft connection in the connecting mechanism into a rigid connection.

[0007] Furthermore, the connecting mechanism includes: a support plate, fixedly disposed on the outer wall of the first pipe and the second pipe; a horizontal plate, fitted against the inner side of the support plate; a connecting cloth, fixedly disposed on the inner side of the horizontal plate; and a sealing strip disposed inside the connection between the support plate and the horizontal plate; wherein, after the support plate and the horizontal plate are fitted together, the connection is fixed by bolts and then the connection is effectively sealed by the sealing strip.

[0008] Furthermore, grooves matching the sealing strip are provided on the inner side of the support plate and the outer side of the cross plate.

[0009] Furthermore, the connecting fabric is a soft, sealing material.

[0010] Furthermore, the auxiliary mechanism includes: a slotted plate, fixedly disposed on the outer wall of the horizontal plate; an insert plate, inserted into the interior of the slotted plate; a slotted block, fixedly disposed on the outer side of the slotted plate; a locking block, inserted into the interior of the slotted block; and a screw, rotatably disposed on the outer side of the insert plate; wherein, when the screw rotates, it drives the locking block to move inward and insert into the interior of the slotted block for limiting.

[0011] Furthermore, the interior of the slot block is provided with a slot that matches the card block.

[0012] Furthermore, a through hole is provided at the center of the card block, and the inner wall of the through hole is threaded to engage with the screw.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows: When in use, the ventilation duct connection structure for coal mine electromechanical engineering achieves a flexible connection at the duct joint through the use of support plates, cross plates, connecting cloth, and sealing strips. Through the combined use of groove plates, insert plates, groove blocks, clamping blocks, and screws, the flexible connection is transformed into a rigid connection. Through the combined use of the above structures, the connection method can be conveniently changed at any time according to different usage needs, thus speeding up the installation progress. Through the mutual cooperation of the connection mechanism and auxiliary mechanism, the connection between ventilation ducts is made tighter and more reliable, and the connection method can be flexibly adjusted according to actual needs, thereby effectively solving the problems existing in traditional ventilation duct connection structures.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a ventilation duct connection structure for coal mine electromechanical engineering, including a first duct 1, a second duct 2, a connecting mechanism 3 and an auxiliary mechanism 4. The first duct 1 and the second duct 2 are connected by the connecting mechanism 3, which is disposed on the outer wall of the first duct 1 and the second duct 2. The auxiliary mechanism 4 is disposed on the outer wall of the connecting mechanism 3 and is used to change the soft connection in the connecting mechanism 3 into a rigid connection.

[0022] Specifically, the connecting mechanism 3 includes: a support plate 301, a cross plate 302, a connecting cloth 303, and a sealing strip 304;

[0023] The support plate 301 is fixedly installed on the outer wall of the first pipe 1 and the second pipe 2. The support plate 301 is used to connect the horizontal plate 302. The horizontal plate 302 is fitted to the inner side of the support plate 301. The horizontal plate 302 is used to support the connecting cloth 303. The connecting cloth 303 is fixedly installed to the inner side of the horizontal plate 302. The sealing strip 304 is installed inside the connection between the support plate 301 and the horizontal plate 302. The sealing strip 304 is used to seal the support plate 301 and the horizontal plate 302. After the support plate 301 and the horizontal plate 302 are fitted together, the connection is fixed by bolts. The sealing strip 304 can effectively seal the connection. The inner side of the support plate 301 and the outer side of the horizontal plate 302 are provided with grooves that match the sealing strip 304. The connecting cloth 303 is a soft material with good sealing performance.

[0024] More specifically, the auxiliary mechanism 4 includes: a slot plate 401, an insert plate 402, a slot block 403, a locking block 404, and a screw 405;

[0025] The slot plate 401 is fixedly installed on the outer wall of the horizontal plate 302. The slot plate 401 is used to support the insert plate 402. The insert plate 402 is inserted into the inside of the slot plate 401. The insert plate 402 is used to rigidly connect the first pipe 1 and the second pipe 2. The slot block 403 is fixedly installed on the outside of the slot plate 401. The locking block 404 is inserted into the inside of the slot block 403. The screw 405 is rotatably installed on the outside of the insert plate 402. When the screw 405 rotates, it can drive the locking block 404 to move inward and insert into the inside of the slot block 403 for limiting. The inside of the slot block 403 is provided with a locking groove that matches the locking block 404. The center of the locking block 404 is provided with a through hole and the inner wall of the through hole is machined with threads to engage with the screw 405.

[0026] Furthermore, the splice 303 is a sealing soft material, optionally including at least one of nitrile rubber, EPDM rubber, fluororubber, silicone rubber, polytetrafluoroethylene or nylon.

[0027] Working principle: When the ventilation duct connection structure for coal mine electromechanical engineering is first used, and the first duct 1 and the second duct 2 need to be connected, the user first moves the horizontal plate 302 and the connecting cloth 303 to the connection points of the first duct 1 and the second duct 2 respectively. Then, the user pushes the horizontal plate 302 outward and fits it against the outer wall of the support plate 301. Then, the bolts pass through the support plate 301 and the horizontal plate 302 to fix them. During fixing, the sealing strip 304 can squeeze the connection points of the support plate 301 and the horizontal plate 302 to achieve a seal. When it is necessary to change the flexible connection of the pipe joint to a rigid connection, the user first inserts the insert plate 402, which drives the screw 405 and the locking block 404 into the inside of the groove plate 401. Then, the user holds the locking block 404 to limit its position. Then, the screw 405 is rotated. By limiting the locking block 404, the locking block 404 moves inward from the outer wall of the screw 405 to the inside of the groove plate 403 when the screw 405 is rotated. After the locking block 404 moves into the inside of the groove plate 403, it can limit the insert plate 402. By limiting the insert plate 402 to the inside of the groove plate 401, the flexible connection of the pipe joint can be changed to a rigid connection.
