Description

Technical Field

[0001] This utility model belongs to the technical field of coal mine ventilation equipment, specifically relating to a wind speed regulator for coal mine ventilation. Background Technology

[0002] Coal mine ventilation speed regulators are crucial equipment in coal mine ventilation systems. Their function is to measure, monitor, and regulate airflow velocity within the mine to ensure air circulation and that air quality meets safety standards. Also known as air volume regulators or dampers, coal mine ventilation speed regulators are indispensable terminal accessories in ventilation, air conditioning, and air purification projects in industrial plants and civil buildings. They are typically installed in ventilation system ducts to regulate the airflow in branch pipes and can also be used for mixing and regulating fresh and return air.

[0003] When in use, ventilation duct airflow regulators generally rely on mechanical structures such as butterfly valves to adjust the airflow speed. However, long-term airflow erosion inside the ventilation duct and frequent opening and closing of the butterfly valve can easily cause wear on components of the adjustment mechanism, such as the slots, springs, and handles, leading to inflexible adjustment or even malfunction, affecting service life and adjustment effect. Therefore, it is necessary to regularly inspect and replace worn parts. However, the existing ventilation ducts are fixed to the coal mine ventilation pipes by clamps and bolts, making it impossible to quickly pull and disassemble the regulating duct during maintenance. This results in difficult maintenance operations, requiring professional personnel to spend a lot of time and effort on maintenance. To address this, we propose a wind speed regulator for coal mine ventilation. Utility Model Content

[0004] The purpose of this utility model is to provide a wind speed regulator for coal mine ventilation, so as to solve the problem that the wind speed regulator for coal mine ventilation mentioned in the background art is not convenient to inspect and maintain.

[0006] Preferably, the side-pull sliding connection assembly includes symmetrically opened grooves on the side of the end of the coal mine ventilation duct and symmetrically fixed sliders at both ends of the regulating air duct, wherein the sliders are slidably connected to the grooves.

[0007] Preferably, guide grooves are provided on both sides of the inner side of the slide groove, and a guide block is fixed to the end of the slider, and the guide block is slidably connected to the guide groove.

[0008] Preferably, the slider has symmetrical slots on both sides, and the inner wall of the slots is symmetrically fixed with buckles, which engage with the slots.

[0010] Preferably, the assembly fastening component includes locking holes symmetrically opened at the ends of the coal mine ventilation duct and through holes symmetrically opened at both ends of the regulating air duct. The end of the regulating air duct is provided with a locking rod that passes through the inside of the through hole and connects to the locking hole. The locking rod is screwed and fixedly connected to the locking hole.

[0011] Preferably, the grip anti-slip mechanism includes a rubber anti-slip ring fitted onto the surface of the adjusting rod.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[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 Figures 1 to 5 This utility model provides a technical solution: a wind speed regulator for coal mine ventilation, including an adjusting air duct 2 installed inside the coal mine ventilation duct 1, an air volume regulator 3 fixed at the top of the adjusting air duct 2, an adjusting rod 4 connected to the top of the air volume regulator 3, a side-pull disassembly and maintenance mechanism between the adjusting air duct 2 and the coal mine ventilation duct 1, and a gripping anti-slip mechanism on the surface of the adjusting rod 4. The side-pull disassembly and maintenance mechanism includes a side-pull sliding connection component and an assembly fastening component.

[0022] In this embodiment, preferably, the side-pull sliding connection assembly includes a sliding groove 100 symmetrically opened on the side of the end of the coal mine ventilation duct 1 and a slider 101 symmetrically fixed at both ends of the regulating air duct 2. The slider 101 is slidably connected to the sliding groove 100, which facilitates the connection between the regulating air duct 2 and the coal mine ventilation duct 1.

[0023] In this embodiment, preferably, guide grooves 200 are provided on both sides of the inner side of the slide groove 100, and a guide block 201 is fixed at the end of the slider 101, and the guide block 201 is slidably connected to the guide groove 200.

[0024] In this embodiment, preferably, the slider 101 has symmetrical slots 300 on both sides, and the inner wall of the slot 100 is symmetrically fixed with buckles 301. By engaging the buckles 301 with the slots 300, the slider 101 can be limited to the inside of the slot 100, and the locking hole 500 and the through hole 501 can be accurately aligned.

[0025] In this embodiment, preferably, the side of the adjusting air duct 2 is symmetrically fixed with an operating handle 400, which facilitates the lateral sliding of the adjusting air duct 2.

[0026] In this embodiment, preferably, the assembly fastening component includes locking holes 500 symmetrically opened at the end of the coal mine ventilation duct 1 and through holes 501 symmetrically opened at both ends of the regulating air duct 2. The end of the regulating air duct 2 is provided with a locking rod 502 that passes through the inside of the through hole 501 and connects to the locking hole 500. The locking rod 502 is screwed and fixedly connected to the locking hole 500, so that the regulating air duct 2 can be firmly locked when it is assembled with the coal mine ventilation duct 1.

[0027] In this embodiment, preferably, the grip anti-slip mechanism includes a rubber anti-slip ring 600 sleeved on the surface of the adjusting rod 4, which facilitates anti-slip function when the adjusting rod 4 is gripped and rotated.

[0028] The working principle and usage process of this utility model are as follows: When it is necessary to replace the worn parts inside the regulating air duct 2, first loosen the locking rod 502 so that its end exits from the inside of the locking hole 500 and screws into the inside of the through hole 501, thereby releasing the locking of the regulating air duct 2. Then, hold the operating handle 400 and pull the regulating air duct 2 outward, causing the slider 101 to slide from the inside of the slide groove 100 and the guide block 201 to slide outward from the inside of the guide groove 200. At the same time, the buckle 301 is squeezed and separated from the slot 300, allowing the regulating air duct 2 to be pulled off from the inside of the end of the coal mine ventilation pipe 1. Then, the worn parts inside the regulating air duct 2 can be replaced and maintained. When adjusting the wind speed inside the regulating air duct 2, the adjusting rod 4 can be rotated, and the rubber anti-slip ring 600 provides a gripping and anti-slip function, allowing for easy rotation.
