Description

Technical Field

[0001] This utility model relates to the field of tunnel monitoring technology, and in particular to a tunnel gas detection device. Background Technology

[0002] Underground tunnel operations are affected by various factors such as geological conditions, environment, and toxic and harmful gases. Among the various toxic and harmful gases, methane is the most dangerous. It is a hydrocarbon gas stored in coal seams and is a flammable and explosive gas.

[0003] The utility model patent with patent authorization announcement number CN220869473U discloses a tunnel gas detection device, including a base, an equipment slot inside the base, and a dual-axis motor movably mounted inside the equipment slot via bearings. Moving slots are provided on the inner walls of both sides of the equipment slot, and a positioning slot is provided at the bottom of the moving slot. A positioning rod is inserted into the positioning slot, and a screw is installed at the output end of the dual-axis motor via a coupling.

[0004] However, the above-mentioned detection device still has some shortcomings in actual use. The most obvious ones are that the overall size of the equipment is too large and the structure is too complicated. It is inconvenient to move it from the ground to the inside of the tunnel and to move and use it inside the tunnel. The actual use effect is not ideal.

[0005] Therefore, it is necessary to invent a tunnel gas detection device to solve the above problems. Utility Model Content

[0006] The purpose of this utility model is to provide a tunnel gas detection device. By incorporating an unfolding mechanism and a folding counterweight mechanism, the operator can directly pick up the cylindrical shell in normal conditions to move the device. When needed, the push ring is manually pushed downwards along the cylindrical shell. As the push ring moves downwards, it pushes the inclined surface at the end of the support plate, causing the support plate to rotate around the rotation axis until it rotates from a vertical to a horizontal position to reinforce the support. Then, rotating the knob causes the locking screw to move inwards and press against the cylindrical shell, locking the push ring. This solves the problems mentioned in the background art, such as the device's large overall size and complex structure, which are inconvenient to transfer from the ground to the tunnel and to move and use within the tunnel, resulting in less than ideal practical performance.

[0007] According to one aspect of this disclosure, the following technical solution is provided: a tunnel gas detection device, comprising:

[0008] A gas detection device, used to detect the gas concentration inside the tunnel;

[0009] Deployment mechanism, the deployment mechanism being used to actuate the folding counterweight mechanism to deploy; and

[0010] A folding counterweight mechanism, comprising a counterweight base, a mounting slot, a rotating shaft, a support plate, and a torsion spring;

[0011] The counterweight base is fixedly installed at the bottom of the columnar shell. Multiple mounting slots are provided, and the multiple mounting slots are evenly opened on the outside of the counterweight base. The rotating shaft is rotatably nested in the mounting slot through a bearing. The support plate is fixedly sleeved on the outside of the rotating shaft. The torsion spring is sleeved on the outside of the rotating shaft and fixedly connected between the inner wall of the mounting slot and the support plate.

[0012] According to at least one embodiment of the tunnel gas detection device of the present disclosure, the gas detection mechanism includes a cylindrical housing, a battery compartment is disposed inside the cylindrical housing, and a storage battery is disposed inside the battery compartment.

[0013] According to at least one embodiment of the tunnel gas detection device of the present disclosure, the gas detection mechanism further includes a movable door and a gas sensor. The movable door is movably connected to the side of the columnar housing via a hinge, and the gas sensor is fixedly disposed at the top of the columnar housing and electrically connected to a battery.

[0014] According to at least one embodiment of the tunnel gas detection device of the present disclosure, the deployment mechanism includes a push ring, which is slidably sleeved on the outside of the columnar housing in a vertical direction.

[0015] According to at least one embodiment of the tunnel gas detection device of this disclosure, the deployment mechanism further includes a locking screw, which is disposed through the right side of the push ring and threadedly connected to the push ring.

[0016] According to at least one embodiment of the tunnel gas detection device of this disclosure, the deployment mechanism further includes a knob fixedly disposed at the right end of the locking screw.

[0017] The technical effects and advantages of this utility model are as follows:

[0018] This invention features an unfolding mechanism and a folding counterweight mechanism, allowing the operator to easily pick up the cylindrical shell in its normal state to move the device. When needed, the push ring is manually pushed downwards along the cylindrical shell. As the push ring moves downwards, it pushes the inclined surface at the end of the support plate, causing the support plate to rotate around the rotation axis until it rotates from a vertical to a horizontal position to reinforce the support. Then, rotating the knob moves the locking screw inwards and presses it against the cylindrical shell to lock the push ring. Compared to existing devices of the same type, this invention is compact, easy to move and use, has stronger practical applicability, and is more ideal for use. Attached Figure Description

[0027] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., as in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” other components or features would subsequently be positioned “above” said other components or features. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0028] Figure 1 This is a schematic diagram of the overall structure of a tunnel gas detection device according to one embodiment of the present disclosure.

[0029] Figure 2This is a schematic diagram of the gas detection mechanism 1 and the deployment mechanism 2 of a tunnel gas detection device according to one embodiment of the present disclosure.

[0030] Figure 3 This is a schematic diagram of the folding counterweight mechanism 3 of a tunnel gas detection device according to one embodiment of the present disclosure.

[0031] like Figures 1-3 As shown, the tunnel gas detection device disclosed herein may include components such as a gas detection mechanism 1, an unfolding mechanism 2, and a folding counterweight mechanism 3.

[0032] like Figure 2 As shown in this disclosure, the gas detection mechanism 1 includes a cylindrical housing 11, a movable door 12, and a gas sensor 13. The cylindrical housing 11 has a battery compartment inside, and a storage battery is installed inside the battery compartment. The movable door 12 is movably connected to the side of the cylindrical housing 11 via a hinge. The gas sensor 13 is fixedly installed at the top of the cylindrical housing 11 and is electrically connected to the storage battery.

[0033] Therefore, under normal conditions, the operator can directly pick up the cylindrical housing 11 to move the device. When the device is placed in the detection position inside the tunnel, the battery powers the gas sensor 13, enabling the gas sensor 13 to continuously detect the gas concentration at the placement position.

[0034] like Figure 2 As shown, in a preferred embodiment, the unfolding mechanism 2 includes a push ring 21, a locking screw 22, and a knob 23. The push ring 21 is slidably sleeved on the outside of the columnar housing 11 in the vertical direction. The locking screw 22 passes through the right side of the push ring 21 and is threadedly connected to the push ring 21. The knob 23 is fixedly disposed at the right end of the locking screw 22.

[0035] Therefore, when needed, the push ring 21 can be manually pushed downward along the cylindrical housing 11. When the push ring 21 moves downward, the folding counterweight mechanism 3 is unfolded to reinforce the support. Then, the knob 23 is rotated, which in turn drives the locking screw 22 to move inward and press against the cylindrical housing 11 to lock the push ring 21.

[0036] like Figure 3As shown in this disclosure, the foldable counterweight mechanism 3 includes a counterweight base 31, a mounting groove 32, a rotating shaft 33, a support plate 34, and a torsion spring 35. The counterweight base 31 is fixedly disposed at the bottom end of the columnar housing 11. Multiple mounting grooves 32 are provided, and the multiple mounting grooves 32 are evenly opened on the outside of the counterweight base 31. The rotating shaft 33 is rotatably nested in the mounting groove 32 through a bearing. The support plate 34 is fixedly sleeved on the outside of the rotating shaft 33. The torsion spring 35 is sleeved on the outside of the rotating shaft 33 and fixedly connected between the inner wall of the mounting groove 32 and the support plate 34.

[0037] Thus, after the inclined surface at the end of the support plate 34 is pushed, the support plate 34 rotates around the rotation axis 33 until it rotates from a vertical state to a horizontal state, thereby completing the reinforcement and support of the counterweight base 31.
