Description

Technical Field

[0001] This utility model belongs to the field of sensor technology, and in particular relates to a dust sensor for mining. Background Technology

[0002] Mining sensors are specialized devices used in mining environments (mainly coal mines and metal and non-metal mines) to monitor and sense various physical, chemical, or state parameters, and convert them into measurable signals (usually electrical signals). They are the core sensing units of modern mining technology equipment such as mine safety monitoring and control systems, automated control systems, and personnel positioning systems.

[0003] Currently, sensors used in mines and other similar environments are heavily corroded by dust, which not only affects the accuracy of the sensing data but also reduces the lifespan of the sensors, requiring frequent cleaning or replacement.

[0004] To address the aforementioned issues, this application proposes a dust sensor for mining applications. Utility Model Content

[0005] The purpose of this invention is to provide a dust sensor for mining, which solves the problems mentioned in the background art.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model is a dust sensor for mining, including a sensor;

[0008] The sensor is equipped with a dual-channel air intake mechanism at its bottom. The center of the dual-channel air intake mechanism is a main pipe, and multiple secondary pipes are connected to the lower outer side of the main pipe. An air intake cylinder is rotatably installed at the lower end of each secondary pipe.

[0009] The lower end of the secondary pipe and the upper end of the air inlet are both equipped with filters, and the adjacent filters fit together.

[0010] Preferably, a sealing cylinder is slidably installed on the outer side of the air inlet cylinder, having a first working state and a second working state.

[0011] Preferably, in the first working state, the sealing cylinder blocks the bottom of the air inlet cylinder and the opening in the pipe wall, and in the second working state, the sealing cylinder moves downward to below the air inlet cylinder.

[0012] Preferably, the upper outer side of the air inlet cylinder has an integrally formed protruding ring, and the lower end of the protruding ring is equipped with an electric telescopic device, the movable end of which is fixedly connected to the upper end of the sealing cylinder.

[0013] Preferably, the lower outer side of the secondary tube has an integral boss, and an annular opening groove is formed on the outer side of the boss.

[0014] Preferably, a rotating block is movably mounted on the upper end of the convex ring, and the inner part of the rotating block is located inside the annular opening groove.

[0015] Preferably, the inner side of the rotating block is embedded with balls.

[0016] This utility model has the following beneficial effects:

[0017] This invention uses a main channel and a secondary channel to intake air in a coordinated manner, which can activate the other secondary channel when one secondary channel is blocked, thereby extending the overall service life of the sensor and achieving long-term operation without the need for frequent cleaning or replacement.

[0018] Furthermore, the rotation of the air intake cylinder causes two adjacent filter screens to rub against each other, thereby causing the adsorbed dust to fall off. This simple operation allows for quick unclogging, making it suitable for cleaning and maintaining batches of sensors in mines.

[0019] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] 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.

[0029] In the description of this utility model, it should be understood that the terms "opening", "top and bottom", "thickness", "top", "middle", "length", "inner" and "around" indicate the orientation or positional relationship only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0030] Please see Figure 1-4 As shown, this utility model is a dust sensor for mining, including sensor 11;

[0031] The sensor 11 is equipped with a dual-channel air intake mechanism at the bottom. The main pipe 121 is connected to the bottom of the sensor 11 at the center. Two secondary pipes 122 extend outward from the lower end of the main pipe 121, extending obliquely downward, and the lower end is a vertically downward pipe. An air intake cylinder 123 is rotatably installed at the lower end of the secondary pipe 122. The pipe wall of the air intake cylinder 123 is evenly provided with holes.

[0032] Both the secondary pipe 122 and the air inlet cylinder 123 are equipped with filters 125. The two filters 125 are located at opposite ends, and the upper and lower adjacent filters 125 are in close contact with each other. When the air inlet cylinder 123 rotates, the upper filter 125 rubs against the lower filter 125, causing the dust intercepted by the lower filter 125 to fall off.

[0033] Furthermore, a sealing cylinder 124 is slidably installed on the outer side of the air intake cylinder 123. The bottom is a sealing structure. When the sealing cylinder 124 is located outside the air intake cylinder 123, it blocks the bottom opening and pipe wall holes of the air intake cylinder 123. When the sealing cylinder 124 is located below the air intake cylinder 123, it releases the blockage on the bottom opening and pipe wall holes of the air intake cylinder 123, thereby starting air intake.

[0034] Furthermore, the upper outer side of the air intake cylinder 123 has a protruding ring 1231, and the two are an integral structure. The lower end of the protruding ring 1231 is equipped with an electric telescopic device 12311, and its movable end is fixedly connected to the plate extending outward from the upper end of the sealing cylinder 124.

[0035] Furthermore, the lower outer side of the secondary tube 122 is integrally provided with a boss 1221, and an annular opening groove is provided on the outer side of the boss 1221, forming a stepped annular mechanism on the outer side of the secondary tube 122.

[0036] Among them, the upper end of the convex ring 1231 has a rotating block 1232. The two rotating blocks 1232 are joined together to form a ring structure, which is rotatably connected with the annular opening groove. The rotating block 1232 is fixedly installed on the upper end of the convex ring 1231 by bolts.

[0037] Furthermore, ball bearings 12321 are embedded inside the rotating block 1232 to reduce the rotational resistance of the air intake cylinder 123 and prevent it from being blocked or jammed by dust entering the gap.

[0038] It is understandable that this utility model utilizes the alternating air intake method of dual air intake channels, which can promptly replace the other channel after one channel is blocked, thereby maintaining the normal working state of the sensor 11 before cleaning and maintenance. This reduces the frequency of cleaning and maintenance, ensures the accuracy of data sensing, and can also quickly clean up accumulated dust during cleaning and maintenance, making it suitable for the cleaning and maintenance of batches of sensors 11.

[0039] A specific application of the operation process of this embodiment is as follows: During use, the gas in the mine first flows into the main pipe 121 through the secondary pipe 122 on one side, and is filtered by the filter screen 125 at the same time as it enters, thereby intercepting dust. When the filter screen 125 is blocked, the sealing cylinder 124 at the lower end of the other secondary pipe 122 is separated from the air inlet cylinder 123 by the electric telescopic device 12311, forming a gas inlet opening. At this time, the gas switching channel flows into the main pipe 121, which can not only maintain a stable working state, but also extend the running time of the equipment and reduce the frequency of cleaning and maintenance. Furthermore, by rotating the air inlet cylinder 123, the upper and lower adjacent filter screens 125 are made to rub against each other, which can cause the dust intercepted by the lower filter screen 125 to fall downward, thereby forming a cleaning effect. The operation is convenient and the cleaning can be completed in a short time.
