Description

Technical Field

[0001] The present invention relates to the technical field of on-the-spot detection, and in particular to a sensor fixing device that is convenient for on-the-spot detection. Background Art

[0002] With the advancement of intelligent coal mining technology, sensors, as core data acquisition equipment, play a key role in gas concentration monitoring, roof pressure detection, equipment operation status perception and other aspects. However, the current underground working environment is complex and changeable, the tunnel section is irregular, and the equipment moves frequently. Traditional sensor fixing devices generally have poor adaptability and low installation efficiency. The bolt fixing method takes a long time to install and is difficult to meet the needs of mining and measuring at any time; magnetic or snap-on fixing is easily disturbed in humid and high-dust environments, and is easy to loosen and fall off under vibration conditions, resulting in interruption or distortion of monitoring data, and even causing damage to the sensor, seriously affecting the safety and efficiency of mining operations. In addition, the existing device lacks a flexible adjustment structure and cannot adapt to sensors of different specifications and complex installation surfaces. Therefore, the development of a sensor fixing device that is easy to install, stable and can be quickly adjusted is of great significance to ensuring intelligent and safe coal mining.

[0003] However, the existing on-site detection sensor fixing device is not convenient for quick installation of the sensor during use. When installing the sensor, the staff needs to spend a lot of time to perform complex operations, which not only increases labor costs but also delays the construction progress. Summary of the Invention

[0004] The purpose of the present invention is to provide a sensor fixing device that is convenient for use in on-the-spot detection. By setting up a mounting part, the problem that the existing on-the-spot detection sensor fixing device is not convenient for quick installation of the sensor during use is solved. When installing the sensor, the staff needs to spend a lot of time to perform complex operations, which not only increases labor costs but also delays the construction progress.

[0005] To solve the above technical problems, the present invention is achieved through the following technical solutions: The present invention is a sensor fixing device that is convenient for use in on-the-spot detection, comprising an outer box with one side open and the other side closed, a notch provided at the bottom center of the outer box, support parts provided on the inner walls of the outer box on both sides of the notch, a sensor provided in the space enclosed by the support parts, the notch and the inner wall of the outer box, and further comprising: a mounting part, the mounting part being mounted on the support part and used for mounting the sensor; an anti-slip part, the anti-slip part being provided with two, both of which are located in the outer box, the tops of the two anti-slip parts extending to the outside of the outer box, the anti-slip part being used to prevent the sensor from loosening after the mounting part has mounted the sensor; an unlocking part, the unlocking part being mounted on the top of the outer box, the unlocking part being located between the two anti-slip parts, and the unlocking part being used to unlock the anti-slip part when the sensor is disassembled.

[0006] Furthermore, the mounting portion includes a limiting assembly, which includes two brackets fixedly connected to the two supporting portions, one side of the two brackets being fixedly connected to one side of the closed surface of the outer box with two inverted L-shaped connecting portions, an extension portion being fixedly connected to the inner wall of the closed surface of the outer box, a gap being formed between the extension portion and the horizontal ends of the two inverted L-shaped connecting portions, and a spring being fixedly connected to the inner wall of the closed surface of the outer box; a transmission assembly, which includes two racks slidably connected in the gap, a rotating shaft being rotatably connected between the inner walls of both sides of the outer box, and two gears meshing with the racks being sleeved on the rotating shaft.

[0007] The top of the second spring is fixedly connected to the top of the inner wall of the slide groove, and the bottom of the second spring is fixedly connected to the block second.

[0008] Furthermore, the unlocking portion includes two door-shaped brackets three fixedly connected to the top of the outer box, the inner walls of the two door-shaped brackets three are slidably connected with sliders, and a rotating member is rotatably connected between the two sliders. The rotating member includes a rotating shaft two rotatably connected in the slider, and the outer wall of the rotating shaft two is fixedly connected with a protective plate located between the two door-shaped brackets three, and the two ends of the rotating shaft two are fixedly connected to two cams located on the outside of the door-shaped bracket three, and the two ends of the rotating shaft two are rotatably connected to two connecting blocks respectively.

[0009] Furthermore, it also includes a limiting member, which includes a bracket 2 slidably connected between two brackets 1, and the bracket 2 is in a dam type that surrounds the sensor. The top of the bracket 2 is fixedly connected to two racks, and the end of the spring 1 is fixedly connected to the bracket 2. Windows are opened on both side walls of the bracket 2, and a card block 1 is hinged in the window. The side of the card block 1 facing the sensor is plugged into the sensor.

[0010] The present invention has the following beneficial effects: (1) The present invention provides a mounting portion. When the sensor needs to be installed in the outer box, the sensor can be placed in the groove of the bracket 2, and then the two clamping blocks 1 are buckled so that the side close to the sensor can clamp the protrusion on the sensor. Then the bracket 2 can be pushed to slide into the outer box under the action of the bracket 1, and pressure is applied to the spring 1 to cause it to undergo elastic deformation and generate elastic force. When the bracket 2 slides, the gear and the shaft 1 will rotate through the rack. When the bracket 2 slides into the outer box, the movement of the clamping block 1 will be restricted under the action of the bracket 1, thereby clamping the sensor in the bracket 2. Then the protective plate cover is covered. The sensor can be installed in the outer box through simple operations, without the need for staff to spend a lot of time on its installation. This not only reduces labor costs but also ensures construction progress.

[0011] (2) The present invention sets an anti-slip portion. When the rotating shaft 1 rotates, it drives the ratchet gear to rotate. When the ratchet gear rotates, it causes the clamping block 2 to slide into the slide groove, and at the same time, the spring 2 undergoes elastic deformation and generates elastic force. When the clamping block 2 rises, the connecting rod slides into the connecting block. When the sensor is installed, the ratchet gear stops rotating, and the clamping block 2 will clamp the ratchet gear under the action of the elastic force of the spring 2, which can not only clamp the installation part to prevent it from resetting under the action of the elastic force of the spring 1, but also can confine the sensor in the outer box after it is installed in the outer box to prevent the sensor from popping out of the outer box under the action of the elastic force of the spring 1, thereby ensuring that the installation part can operate stably.

[0012] (3) The present invention sets an unlocking part. When the sensor needs to be disassembled, the protective plate can be opened and rotated upward 180 degrees. During this process, the protective plate will drive the cam to rotate through the rotating shaft 2. When the rotation angle is greater than 90 degrees, the slider will be lifted under the action of the cam, and the lifted slider will slide under the restriction of the bracket 3. At the same time, the rotating shaft 2 will also be lifted, and the lifted rotating shaft 2 will drive the connecting block to be lifted. At this time, under the action of the limit block, the card block 2 will be driven to slide into the slide groove through the connecting rod, thereby unlocking the ratchet gear. At this time, under the action of the elastic force of the spring 1, the bracket 2 without restriction will be ejected from the bracket 1, and then the sensor can be removed. When the sensor needs to be disassembled, the anti-slip part can be unlocked, so that the installation part can be quickly reset, thereby improving the disassembly efficiency.

[0013] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

When the protective plate 404 is closed, the two cams 405 rotate upward. By providing the unlocking portion 4, the anti-detachment portion 3 can be unlocked when the sensor 102 needs to be disassembled, so that the mounting portion 2 can be quickly reset, thereby improving the disassembly efficiency. It also includes a limiting member, which includes a bracket 213 slidably connected between two brackets 1 211, and the bracket 2 is in the form of a dam that surrounds the sensor. The top of the bracket 213 is fixedly connected to two racks 221, and the end of the spring 1 212 is fixedly connected to the bracket 213. Windows are provided on both side walls of the bracket 213, and a block 1 214 is hinged in the window. The side of the block 1 214 facing the sensor is plugged into the sensor 102.

[0022] When in use, when the sensor 102 needs to be installed in the outer box 101, the sensor 102 can be placed in the slot of the bracket 213. The sensor 102 is a KGJ16B gas sensor. Its working principle is that when air containing gas enters the working chamber of the sensor, the gas catalytically burns on the surface of the detection element, causing the temperature of the detection element to rise and the resistance value to change. The change in the resistance value of the detection element will cause the bridge to be unbalanced, generating a voltage signal proportional to the gas concentration. After amplification, filtering and other processing, this voltage signal is converted into a digital signal, which is further processed and calculated by the microprocessor, and finally the calculated gas concentration is converted into a digital signal. The value is displayed and an early warning is issued, and then the two card blocks 1 214 are buckled on both sides of the sensor. The card block 1 is connected to the sensor through a connector, and then the bracket 213 can be pushed to slide into the outer box 101 under the guidance of the bracket 1 211, and pressure is applied to the spring 1 212 to cause it to elastically deform and generate elastic force. While the bracket 213 slides, the gear 223 and the shaft 1 222 are driven to rotate through the rack 221. When the bracket 213 slides into the outer box 101, the sensor 102 is stuck in the bracket 213 through the card block 1 214. When the shaft 1 222 rotates, it drives the ratchet gear 313 to rotate, and the ratchet gear 313 is driven to rotate. When the gear 313 rotates, it pushes the second block 312 to slide upward in the slide groove 311, and at the same time, the second spring 322 is elastically deformed and generates elastic force. When the second block 312 rises, the connecting rod 321 moves in the connecting block 323. When the sensor 102 is installed, the ratchet gear 313 stops rotating, and the second block 312 will jam the ratchet gear 313 under the action of the elastic force of the second spring 322, which can jam the installation part 2 to prevent it from resetting under the action of the elastic force of the first spring 212. When the sensor 102 needs to be disassembled, the protective plate 404 can be opened and rotated to rotate upward. In this process, the protective plate 404 04 will drive the cam 405 to rotate through the rotating shaft 2 403. When the rotation angle is greater than 90 degrees, the slider 402 will be lifted under the action of the cam 405, and the lifted slider 402 will slide upward under the constraint of the bracket 3 401. At the same time, the rotating shaft 2 403 will also be lifted, and the lifted rotating shaft 2 403 will drive the connecting block 323 to be lifted. At this time, under the action of the limit block 324, the card block 2 312 will be driven to rise in the slide groove 311 through the connecting rod 321, thereby unlocking the ratchet gear 313. At this time, under the action of the elastic force of the spring 1 212, the bracket 2 213 that has lost its restriction will be ejected from the bracket 1 211, and then the sensor 102 can be removed.
