Description

Technical Field

[0001] The utility model relates to the field of smoke sensors, in particular to a mine smoke sensor which is convenient for installation. Background Technique

[0002] The mine smoke sensor is a device designed specifically for high-risk environments such as coal mines. It is mainly used to monitor fire accidents in coal mine shafts caused by mechanical failure friction, cable heating, coal seam spontaneous combustion, etc., so as to achieve the effect of early prevention. The mine smoke sensor mainly works based on the principle of photoelectric induction. Its core components include an infrared light-emitting diode and a photosensitive resistor. When infrared light passes through the particles in the smoke, part of the light will be scattered by the smoke particles, increasing the degree of light scattering. The sensor captures and calculates the intensity of the scattered light, converts the smoke concentration into an electrical signal, and thus realizes the monitoring of the smoke concentration. When the smoke concentration reaches the preset threshold, the sensor will output an alarm signal to remind relevant personnel to take measures.

[0003] In the prior art, most mine smoke sensors are installed by hanging on hooks in the mine tunnel through hanging rings or installed on installation brackets in the mine tunnel through bolts. Although the hanging installation method can achieve the purpose of facilitating the installation of the mine smoke sensor, after installation, the stability is poor. The mine smoke sensor is prone to shaking and dropping and breaking under the influence of external factors. When installing the mine smoke sensor with bolts, although the problem of stable and firm installation can be achieved, the operation during installation is relatively troublesome, resulting in inconvenient disassembly and maintenance of the mine smoke sensor even when a fault occurs later, thus causing inconvenience to the disassembly, installation and use of the mine smoke sensor. Content of the Utility Model

[0004] The main purpose of the utility model is to provide a mine smoke sensor which is convenient for installation, and can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0006] A mine smoke sensor which is convenient for installation, comprising a fixed seat and a smoke sensor body. The smoke sensor body is fixedly connected to the bottom surface of the fixed seat through an installation mechanism on the top surface. The installation mechanism includes an installation seat, a fixed rod, a compression spring, a movable block, an L-shaped connecting block and a movable sleeve. The installation seat is fixedly connected to the top surface of the smoke sensor body, and a group of symmetrical fixed rods are fixedly connected to the top surface of the installation seat. The compression spring is sleeved outside the fixed rod, and the movable block is movably connected to the fixed rod through a connecting hole on the side wall and fixedly connected to the outer end of the compression spring. The L-shaped connecting block is fixedly connected to the top surface of the movable block, and a movable sleeve is also fixedly connected to the outer side wall of the movable block.

[0007] Preferably, mounting holes are respectively formed on four sides of the top surface of the fixing base, and bolts are inserted and mounted in the holes of the mounting holes.

[0008] Preferably, a set of horizontally symmetric connecting ports are formed on the bottom surface of the fixing base, and a set of horizontally symmetric side ports communicating with the connecting ports are formed on the outer wall of the fixing base.

[0009] Preferably, the mounting base is fixedly mounted on the top surface of the smoke sensor body, and a set of horizontally symmetric movable ports are formed on the top surface of the mounting base. Sliding grooves are respectively formed on the front and rear side walls inside the movable ports, and a set of horizontally symmetric through holes communicating with the movable ports are further formed on the outer wall of the mounting base.

[0010] Preferably, the fixing rod is fixedly mounted on the inner side wall inside the movable port, and the compression spring is sleeved outside the fixing rod. The inner end of the compression spring is fixedly mounted on the inner side wall inside the movable port.

[0011] Preferably, a connecting hole is formed on the side wall of the movable block and the movable block is movably mounted on the fixing rod through the connecting hole. The movable block is further fixedly mounted on the outer end of the compression spring.

The movable sleeve is fixedly mounted on the outer side wall of the movable block and passes through the through hole, and the movable sleeve is further sleeved on the fixing rod.

[0012] Compared with the prior art, the utility model has the following beneficial effects:

[0013] In the utility model, the provided mounting mechanism is used in cooperation with the smoke sensor body. The fixing base is pre-fixed to the position where the smoke sensor body needs to be mounted in the mine tunnel through bolts. When installing the smoke sensor body, after manually pressing the movable sleeves on both sides of the mounting base inward, the movable sleeves will enter the mounting base and push the movable block to move, forcing the compression spring to retract. The movable block drives the L-shaped connecting block to move inward. Until the movable sleeve cannot be pressed, the L-shaped connecting block is placed in the connecting port and the mounting base is closely attached to the bottom surface of the fixing base. After releasing the pressing of the movable sleeve, under the elastic force of the compression spring, the movable block is pushed outward, so that the horizontal part of the L-shaped connecting block is stuck in the side port, thus achieving the purpose of facilitating the quick installation and fixation of the smoke sensor body, ensuring the stability of the smoke sensor body after installation. At the same time, it is convenient to disassemble in time after the smoke sensor body fails, and thus it is convenient for the disassembly and assembly of the mine smoke sensor.

The connecting ports 6 provided on the fixed seat 1 enable the L-shaped connecting block 17 to move horizontally within the connecting ports 6, so that the horizontal part of the L-shaped connecting block 17 enters and exits within the side ports 7 to complete the disassembly and assembly operations of the smoke sensor body 2;

[0023] As Figure 4 shown, the mounting seat 8 is fixedly installed on the top surface of the smoke sensor body 2, and a set of horizontally symmetric movable ports 9 are provided on the top surface of the mounting seat 8. Sliding grooves 10 are respectively provided on the front and rear inner side walls of the movable ports 9, and a set of horizontally symmetric through holes 11 that communicate with the movable ports 9 respectively are further provided on the outer wall of the mounting seat 8. The movable ports 9 provided on the top surface of the mounting seat 8 enable the movable block 14 to move horizontally, as well as the installation of the fixed rod 12 and the compression spring 13, and the sliding grooves 10 enable the slider 16 to slide, while the through holes 11 ensure that the movable sleeve 18 enters the movable ports 9;

[0024] As Figure 4 shown, the fixed rod 12 is fixedly installed on the inner side wall of the inner side of the movable port 9, and the compression spring 13 is sleeved on the outside of the fixed rod 12. The inner end of the compression spring 13 is fixedly installed on the inner side wall of the inner side of the movable port 9. By making a retracting or extending operation of the compression spring 13 on the fixed rod 12, the movable block 14 is driven to move outward or inward, and the installation and disassembly of the smoke sensor body 2 are completed through the L-shaped connecting block 17;

[0025] As Figure 4 shown, a connecting hole 15 is provided on the side wall of the movable block 14 and the movable block 14 is movably installed on the fixed rod 12 through the connecting hole 15, and the movable block 14 is also fixedly installed on the outer end of the compression spring 13. Sliders 16 are respectively fixedly installed on the front and rear side walls of the movable block 14, and the sliders 16 are movably installed in the sliding grooves 10. The movable sleeve 18 is fixedly installed on the outer side wall of the movable block 14 and passes through the through hole 11, and the movable sleeve 18 is also sleeved on the fixed rod 12. During the process of manually pressing the movable sleeve 18 to enable the movable sleeve 18 to enter the movable port 9 through the through hole 11, it is inserted onto the fixed rod 12 and pushes the movable block 14 to make the movable block 14 move inward along the fixed rod 12 through the connecting hole 15, and the slider 16 will slide in the sliding groove 10 and force the compression spring 13 to make a retracting operation until the L-shaped connecting block 17 no longer obstructs the installation of the smoke sensor body 2 and enters the movable port 9. After that, under the elastic restoring and extending force of the compression spring 13, the movable block 14 is pushed to insert the horizontal part of the L-shaped connecting block 17 into the side port 7, and the purpose of facilitating the installation of the smoke sensor body 2 can be achieved.

[0026] It should be noted that the present utility model is a mine smoke sensor that is convenient for installation. Before installing the smoke sensor body 2, insert the bolt 5 into the installation hole 4 and fix the fixed seat 1 at the position where the smoke sensor body 2 needs to be installed in the mine tunnel through the bolt 5. When installing the smoke sensor body 2, manually press the movable sleeves 18 on the left and right sides of the mounting seat 8 on the top surface of the smoke sensor body 2.
