Description

Technical Field

[0001] This utility model relates to a multi-combination gas detection component for a safety detection rod. Background Technology

[0002] With the increasing verticality of cities, the density of chemical industrial parks, and the complexity of underground spaces, fire rescue sites often contain multiple toxic, harmful, and flammable gases, such as SO2, H2S, CO, and combustible gases.

[0003] The traditional practice is to install only a gas sensor at the end of the safety probe. Existing probe gas sensor modules are mostly fixed by screws or glue. In the high temperature, high humidity and strong corrosion environment of the fire scene, the screws rust and the glue layer ages, causing the module to loosen and the seal to fail. On-site, sensors with different ranges or principles (such as catalytic combustion / infrared / electrochemical) need to be replaced temporarily depending on the disaster situation, but the existing structure cannot achieve "tool-free" operation, which delays the golden rescue time; Therefore, a multi-combination gas detection component for a safety detection rod is proposed.

The fixed cover has one end connected to the probe rod body via a bolt, and the other end is provided with a locking structure. The fixed cover can switch between an open state and a closed state through the locking structure, and in the closed state, the circuit board and the gas sensor are encapsulated in the mounting slot. The locking structure is used to lock the fixing cover to the rod body when the rod is closed.

[0006] Preferably, the locking structure includes an adjustment groove disposed at one end of the fixing cover, an adjustment plate slidably disposed inside the adjustment groove, and an end button for controlling the position of the adjustment plate disposed on the upper part of the adjustment plate.

[0008] Preferably, the insertion end of the positioning bolt is provided with a double-beveled guide portion, and the lower end of the positioning bolt is provided in a smooth arc shape.

[0009] Preferably, the fixing cover has a moving groove at the upper part of the adjusting groove for linear movement of the end button; The mounting slot has an arc-shaped groove on the side away from the channel for connecting the bolt, so that the fixing cover can be engaged and connected at the arc-shaped groove by the bolt.

All other embodiments obtained by those skilled in the art based on the embodiments of this invention without creative effort are within the scope of protection of this invention.

[0020] Please see Figure 1-7 This utility model provides a multi-combination gas detection assembly for a safety detection rod, including... Installation groove 1, wherein the installation groove 1 is formed on the outer wall side of the probe rod; The circuit board 2 is detachably fixed in the mounting slot 1, and multiple sets of different types of gas sensors are arranged sequentially along its length. A fixed cover 3 is connected to the probe rod body at one end via a bolt 49, and a locking structure 4 at the other end. The fixed cover 3 can switch between an open and a locked state via the locking structure 4, and in the locked state, it encapsulates the circuit board 2 and the gas sensor within the mounting slot 1. The locking structure 4 includes an adjustment slot 41 at one end of the fixed cover 3. An adjustment plate 42 is slidably disposed inside the adjustment slot 41. An end button 43 for controlling the position of the adjustment plate 42 is located on the upper part of the adjustment plate 42. A content slot 44 is opened at the end of the adjustment plate 42 away from the end button 43. A positioning bolt 45 is disposed inside the content slot 44. A limit baffle 46 is disposed on the outer periphery of the positioning bolt 45. A return spring 47 is disposed on the outer periphery of the positioning bolt 45, and the return spring 47 is located on the lower periphery of the limit baffle 46. The insertion end of the positioning bolt 45 is provided with a double-beveled guide portion 451, and the lower end of the positioning bolt 45 is provided in a smooth arc shape.

[0021] The locking structure 4 is used to lock the fixing cover 3 to the rod body when it is closed.

[0022] The fixed cover 3 has a moving groove 48 on the upper part of the adjusting groove 41 for linear movement of the end button 43; the placement groove 1 has an arc-shaped groove 410 on the side away from the channel 101 for connecting the bolt 49, so that the fixed cover 3 is engaged and connected at the arc-shaped groove 410 by the bolt 49. The fixed cover 3 has a detection through hole 6 corresponding to the position of each gas sensor, and a protective plate 7 is embedded in the detection through hole 6.

[0023] The probe rod body has a channel 101 on one side of the mounting groove 1 for inserting the adjustment plate 42, and a positioning hole 5 is provided on the upper part of the channel 101 for engaging the positioning bolt 45.

[0024] The multiple sets of gas sensors include a sulfur dioxide sensor 8, a hydrogen sulfide sensor 9, a carbon monoxide sensor 10, and a combustible gas sensor 11.

[0025] The working principle of the multi-combination gas detection component of the safety detection rod provided by this utility model is as follows: Closing process of the retaining cover 3: Align the fixing cover 3 with the mounting groove 1 of the probe rod body, and ensure that the bolt 49 on the fixing cover 3 is aligned with the arc-shaped groove 410 on the rod body.

[0026] The bolt 49 on the fixed cover 3 is engaged with the arc-shaped slot 410 on the rod body, at which point the cover is in a half-open state.

[0027] Continue pressing down on the cover; the other end of the cover engages with the mounting slot 1. Then, push the adjusting plate 42 via the end button 43, causing the adjusting plate 42 to be inserted into the probe rod body through the channel 101. When the positioning bolt 45 at the adjusting plate 42 moves to the positioning hole 5 on the rod, the double-sloped guide portion 451 on the positioning bolt 45 aligns with the positioning hole 5. Under the elastic force of the return spring 47, the positioning bolt 45 is pushed into the positioning hole 5, so that the positioning bolt 45 is tightly locked in the positioning hole 5. Then, the positioning bolt 45 is rotated, so that the double-sloped guide portion 451 of the positioning bolt 45 rotates to both sides in the moving direction of the adjusting plate 42, and the mechanical locking is completed.

[0028] Opening process of fixing cover 3: Press the positioning bolt 45 downwards through the positioning hole 5 with your finger and rotate the double-sloped guide part 451 of the positioning bolt 45 in the opposite direction to the direction of movement of the adjusting plate 42, so that the double-sloped guide part 451 is located at the lower end face of the positioning hole 5. Then push the end button 43 towards the other end of the fixing cover 3. The end button 43 drives the adjusting plate 42 to move. At this time, the lower end face of the positioning hole 5 presses the double-sloped guide part 451 until the positioning bolt 45 is located at the bottom end face of the positioning hole 5. The movement of the adjusting plate 42 causes the positioning bolt 45 to gradually exit the positioning hole 5. At the same time, the return spring 47 is compressed. When the positioning bolt 45 has completely exited the positioning hole 5, the fixing cover 3 is disconnected from the rod body.

[0029] At this point, the retaining cover 3 can be opened, exposing the circuit board 2 and the gas sensor. Prepare the sensor that needs to be replaced.

[0030] Gently pinch the plug of the old sensor with your hand and pull it out vertically outward to remove it from the socket on circuit board 2.

[0031] Align the plug of the new sensor with the socket on circuit board 2 and insert it gently, ensuring that the plug and socket are firmly connected.

[0032] Hearing a "click" indicates that the sensor has been correctly installed.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
