A mine smoke sensor that is easy to maintain

Abstract

This invention relates to the field of smoke sensors and discloses a mine smoke sensor that is easy to maintain. The smoke sensor includes a fixed base on its top, a resistance structure surrounding its side, and a cleaning structure surrounding the side of the resistance structure. The cleaning structure includes an air pressure tube, a piston slidingly mounted inside the air pressure tube, and a movable rod on one side of the piston. The cleaning structure provided by this invention is linked to the battery compartment. When the operator opens the battery compartment for battery replacement or equipment maintenance, pulling the external pull ring synchronously moves the movable rod and piston outward, filling the air pressure tube with air. During battery replacement and when the battery compartment is closed, the piston pushes inward, evenly discharging the stored air through multiple cleaning tubes, effectively blowing away dust accumulated on the sensor surface. This is especially beneficial if the sensor surface has firmly adhered dust.

Description

Technical Field

[0001] This invention relates to the field of smoke sensor technology, specifically to a mine smoke sensor that is easy to maintain. Background Technology

[0002] The patent application with publication number CN110702854A includes a protective cover mounting base; a fixed connector is fused to the top surface of the protective cover mounting base, and a fixed connector is slidably connected to the fixed connector; a protective cover structure is fastened to the bottom surface of the protective cover mounting base via hook claws, and a detection body is provided at the center of the bottom surface of the protective cover mounting base. The advantages are: the fixed connector can be installed to the wall first, and then the fixed connector can be inserted into the fixed connector. Since each bolt fixing seat has a U-shaped fixing groove, the fixing position can be adjusted appropriately when fixing the device; another option is to use the fixed connector to directly connect to a wire or a thin cylindrical rod. The method is that during use, the rotating connector is connected to the wire or thin cylindrical rod through the bayonet, and then the rotating connector is rotated to complete the connection. Disassembly is convenient, making the device more convenient and flexible when suspended.

[0003] In the prior art, including the aforementioned patents, most smoke sensors used in mine tunnels are installed at the top of the tunnel. Due to the difficulty in laying wires over a large area within the tunnel, most smoke sensors use a battery compartment. However, this requires regular inspection and battery replacement by staff to ensure normal operation. The interior of the mine tunnel is complex and contains a lot of dust and impurities, which can easily accumulate on the smoke sensor over time, affecting its normal operation. Furthermore, since some mine tunnels are relatively low, and the smoke sensors are simply secured by rotating clips on the mounting base, they are easily touched during routine entry and exit from the mine and during battery replacement, causing them to loosen, fall off, and be damaged. Summary of the Invention

[0004] The problems that this invention aims to solve are: smoke sensors are prone to dust accumulation, affecting normal operation, and the rotating latches are prone to loosening.

[0005] To solve the above-mentioned technical problems, the technical solution of the present invention is: a mine smoke sensor that is easy to maintain, including a smoke sensor, a fixed base on the top of the smoke sensor, a resistance structure surrounding the side of the smoke sensor, and a cleaning structure surrounding the side of the resistance structure.

[0006] The cleaning structure includes a pneumatic tube, inside which a piston is slidably mounted. A movable rod is provided on one side of the piston. The movable rod is segmented, and several movable rods are rotatably connected. The movable rod can drive the piston to move along the inside of the pneumatic tube to perform air extraction and exhaust.

[0007] Preferably, the smoke sensor has a battery compartment on its front side, and connecting blocks are fixedly provided on both sides of the front side of the battery compartment. The connecting blocks are rotatably connected to one side of the movable rod.

[0008] Preferably, a one-way air hole is provided at the top of the back of the air pressure pipe, a connecting pipe is fixedly connected to the bottom of the back of the air pressure pipe, and an exhaust pipe is fixedly connected to one side of the connecting pipe.

[0009] Preferably, the surface of the exhaust pipe is fixedly provided with several positioning blocks, the top of the positioning blocks is fixedly connected to the bottom of the smoke sensor, and one side of the inner wall of the exhaust pipe is provided with several cleaning pipes in a circular array.

[0010] Preferably, the exhaust port of the cleaning pipe is inclined, and the air discharged from the cleaning pipe can clean the dust on the surface of the smoke sensor.

[0011] Preferably, the resistance structure includes a connecting ring, the top of which is provided with a plurality of rubber pouches in a circumferential array, and a knob is threaded on one side of the top of the connecting ring.

[0012] Preferably, the connecting ring has an internal air pressure chamber and a connecting pipe, the air pressure chamber and the connecting pipe are fixedly connected, and the connecting pipe is fixedly connected to the rubber soft bag.

[0013] Preferably, the air pressure chamber is provided with a pressure plate inside, and the top of the pressure plate is fixedly connected to the bottom of the knob.

[0014] Preferably, the smoke sensor has push-button switches on both sides of the front side, the push-button switches are adapted to the battery compartment, the battery compartment contains a battery, and the front side of the battery compartment is fixedly connected to a pull ring.

[0015] Compared with the prior art, the technical solution of the present invention has the following advantages:

[0016] (1) The cleaning structure set by the present invention has a significant cleaning effect. The cleaning structure is linked with the battery compartment. When the staff opens the battery compartment to replace the battery or repair the equipment, the movable rod and piston can be moved outward by pulling the external pull ring, so that the air pressure tube is filled with air. When the battery is replaced and the battery compartment is closed, the piston is pushed inward to discharge the stored air evenly through multiple cleaning tubes, thereby effectively blowing away the dust on the sensor surface. If the dust on the sensor surface is firmly attached, the battery compartment can be opened and closed repeatedly to achieve repeated cleaning. The operation is simple and no additional tools are required. The surface of the smoke sensor after cleaning is cleaner, which is in stark contrast to the sensor that has not been replaced for a long time and has a lot of dust. The latter is usually darker in color and has a dull appearance, while the cleaned sensor is obviously white and bright, and easy to identify. Therefore, when the staff replaces the battery, they can intuitively judge its maintenance status based on the cleanliness of the sensor surface, effectively avoiding the omission or repeated replacement due to forgetfulness, and improving the accuracy and efficiency of maintenance work.

[0017] (2) A resistance structure is also provided on the inner side of the cleaning structure. The resistance structure can squeeze and release the air in the air pressure chamber by tightening and loosening the knob. When the knob drives the pressure plate to squeeze the air, the gas can be transported to each rubber soft bag through the connecting pipe to make it expand outward to a certain extent. The expansion range is such that the top of the rubber soft bag contacts the top of the mine tunnel after the smoke sensor is installed on the fixed base, increasing the friction force. This ensures that the smoke sensor will not rotate, loosen or fall off unless it needs to be disassembled and repaired during maintenance, thus greatly increasing the stability of the smoke sensor.

[0032] like Figures 1 to 11 As shown, the present invention provides a mine smoke sensor that is easy to maintain, including a smoke sensor 2, a fixed base 1 on the top of the smoke sensor 2, a resistance structure 5 surrounding the side of the smoke sensor 2, and a cleaning structure 6 surrounding the side of the resistance structure 5.

[0033] The cleaning structure 6 includes a pneumatic pipe 604, inside which a piston 609 is slidably mounted. A movable rod 607 is mounted on one side of the piston 609. The movable rod 607 is segmented, and several movable rods 607 are rotatably connected. The movable rod 607 can drive the piston 609 to move along the inside of the pneumatic pipe 604 to perform air extraction and exhaust.

[0034] The smoke sensor 2 has a battery compartment 3 on its front side. Connecting blocks 606 are fixed on both sides of the front side of the battery compartment 3. The connecting blocks 606 are rotatably connected to one side of the movable rod 607.

[0035] A one-way air hole 608 is provided at the top of the back of the air pressure pipe 604, and a connecting pipe 602 is fixedly connected to the bottom of the back of the air pressure pipe 604. An exhaust pipe 601 is fixedly connected to one side of the connecting pipe 602.

[0036] Several positioning blocks 605 are fixedly provided on the surface of the exhaust pipe 601. The top of the positioning block 605 is fixedly connected to the bottom of the smoke sensor 2. Several cleaning pipes 603 are arranged in a circular array on one side of the inner wall of the exhaust pipe 601.

[0037] The exhaust port of the cleaning pipe 603 is inclined, and the air discharged from the cleaning pipe 603 can clean the dust on the surface of the smoke sensor 2.

[0038] The resistance structure 5 includes a connecting ring 502, the top of which is provided with a number of rubber soft bags 501 in a circumferential array, and a knob 503 is threaded on one side of the top of the connecting ring 502.

[0039] The connecting ring 502 has an internal air pressure chamber 506 and a connecting pipe 504. The air pressure chamber 506 and the connecting pipe 504 are fixedly connected. The connecting pipe 504 is fixedly connected to the rubber soft bag 501.

[0040] The air pressure chamber 506 is equipped with a pressure plate 505, and the top of the pressure plate 505 is fixedly connected to the bottom of the knob 503.

[0041] The smoke sensor 2 has push switches 7 on both sides of the front. The push switches 7 are compatible with the battery compartment 3. The battery compartment 3 contains a battery 8. The front of the battery compartment 3 is fixedly connected with a pull ring 4.

[0042] The working principle and usage process of this invention: When using the device, the operator first installs the smoke sensor 2 onto the mounting base 1. During installation, align the slot on the smoke sensor 2 with the snap-fit ​​component on the mounting base 1, and rotate to lock it in place. After locking, rotate the knob 503. The knob 503 will cause the pressure plate 505 to move downwards, squeezing the air in the pressure chamber 506 into the connecting pipe 504 (both the pressure chamber 506 and the connecting pipe 504 already contain a certain amount of air). The air in the connecting pipe 504 will push the rubber soft bag 501 upwards (the rubber soft bag 501 is surrounded by fixed blocks, so it will not expand outwards). After being pushed up, the top of the rubber soft bag 501 will contact the top of the mine tunnel, greatly increasing the friction between them, making the smoke sensor 2 more secure and stable after installation. Even if disassembly and maintenance are required later, it can be removed simply by loosening the knob 503, without cumbersome unlocking steps, making it more convenient and quick. When replacing the battery 8 in the battery compartment 3... Pressing the pull ring 4 opens the push switches 7 on both sides of the battery compartment 3, allowing it to be pulled out. Once pulled out, the battery compartment 3 moves to one side via the connecting block 606, which in turn moves the piston 609 backward. At this point, the one-way vent 608 begins to draw in air, filling the pressure pipe 604 with air. After replacing the battery 8, the battery compartment 3 is closed. The moving rod 607 then moves the piston 609 inward, closing the one-way vent 608 and allowing the air in the pressure pipe 604 to be discharged through the connecting pipe 602 into the exhaust pipe 601, finally exiting through the cleaning pipe 603 to clean the surface of the smoke sensor 2, removing dust. The cleaned smoke sensor 2 is significantly cleaner, a stark contrast to smoke sensors that have not had their batteries replaced for a long time and have accumulated a lot of dust. When replacing the battery 8, staff can visually judge its maintenance status based on the cleanliness of the sensor surface, avoiding missed or repeated replacements due to forgetfulness.

The scope of protection of the present invention is defined by the claims. Those skilled in the art can make various modifications or equivalent substitutions to the present invention within its spirit and scope of protection, and such modifications or equivalent substitutions should also be considered to fall within the scope of protection of the present invention.
