Description

Technical Field

[0001] The utility model belongs to the field of tunnel environment detection, and particularly relates to a tunnel environment detector with an alarm device. Background Technique

[0002] During the tunnel construction process, environmental detection is required. The tunnel environment detection is mainly to detect the concentration of toxic and harmful gases in the tunnel (such as CO, SO₂, NO, gas, methane, hydrogen sulfide, etc.) to ensure the safety of on-site construction personnel. The on-site environmental conditions are collected through a detector, the concentration of corresponding harmful gases is displayed, and an alarm device such as a buzzer is set on the detector to alarm for data exceeding the critical value.

[0003] When detecting the gas concentration, it is necessary to collect gas data at different positions in the tunnel. For this reason, the detector needs to reach multiple positions in the tunnel (including the tunnel top). However, when performing multi-point environmental detection in the tunnel construction environment, the detector is likely to collide and interfere with the tunnel wall and some construction equipment, resulting in damage to the detector. Therefore, a tunnel environment detector with an alarm device is proposed. Content of the Utility Model

[0027] As Figure 1 shown, a tunnel environment detector with an alarm device includes a base 1. Four universal wheels are provided at the lower end of the base 1 to facilitate the transfer of the environment detector, and thus facilitate the detection of environmental data at different positions in the horizontal direction in the tunnel; and brakes are provided on the universal wheels to facilitate the stopping of the base 1, so as to perform environmental detection;

[0028] Of course, the number of the universal wheels at the lower end of the base 1 includes but is not limited to four in this embodiment. In some embodiments, the number of the universal wheels can also be more than four, as long as it can support the base 1 and ensure its stable transfer.

[0029] A support frame 2 is fixed to the upper end of the base 1. A mounting bracket 3 capable of lifting is provided on the support frame 2. A detector 5 is fixedly installed on the mounting bracket 3. An alarm device is provided on the detector 5. By controlling the lifting of the mounting bracket 3, the detection of environmental data at different heights can be realized. When the detected data exceeds the critical value, an alarm prompt will be given;

[0030] In this embodiment, as Figure 2As shown in the figure, a connecting plate 31 is provided on one side of the mounting bracket 3. The connecting plate 31 is slidably connected to the support bracket 2 in the vertical direction. A first lead screw 4 is rotatably connected to the support bracket 2. The first lead screw 4 penetrates through the connecting plate 31 along the vertical direction and is threadedly connected thereto. By providing a motor on the support bracket 2 to drive the rotation of the first lead screw 4, the lifting of the mounting bracket 3 can be driven, achieving the purpose of adjusting the height positions of the mounting bracket 3 and the detector 5. And to ensure the stability of the mounting bracket 3 after the height position is adjusted, the first lead screw 4 needs to have self-locking, that is, the lead angle of the first lead screw 4 is less than the equivalent friction angle.

[0031] Of course, the ways to drive the lifting of the mounting bracket 3 include but are not limited to the structure of the first lead screw 4 in this embodiment. In some embodiments, a cylinder, a telescopic rod and other linear driving components can also be provided to directly drive the lifting of the mounting bracket 3.

[0032] As Figure 2 shown in the figure, a support plate 32 is fixed on one side of the mounting bracket 3. The detector 5 is placed on the upper end of the support plate 32. A clamping assembly 6 is provided on the mounting bracket 3 to clamp and fix the detector 5 on the upper end of the support plate 32. As Figure 3 shown in the figure, the clamping assembly 6 includes two clamping plates 61 that can slide synchronously and in opposite directions. The two clamping plates 61 approaching synchronously can clamp and fix the detector 5.

[0033] In this embodiment, both of the two clamping plates 61 are slidably connected to the mounting bracket 3. Two first fixing plates 33 are provided on the mounting bracket 3. A second lead screw 62 is rotatably connected between the two first fixing plates 33. First external threads 621 and second external threads 622 with opposite helix directions and equal pitches are provided on the second lead screw 62. The first external threads 621 and the second external threads 622 respectively penetrate through the two clamping plates 61 and are threadedly connected thereto. By providing a motor on one of the first fixing plates 33 to drive the rotation of the second lead screw 62, the synchronous reverse sliding of the two clamping plates 61 can be realized, thereby clamping and fixing the detector 5. And to ensure the stability of the clamping of the detector 5 by the clamping plates 61, the second lead screw 62 needs to have self-locking, that is, the lead angles of the first external threads 621 and the second external threads 622 are both less than the equivalent friction angle.

[0034] Of course, the ways to drive the synchronous reverse sliding of the two clamping plates 61 include but are not limited to the structure of the second lead screw 62 in this embodiment. In some embodiments, two telescopic rods can also be provided on the mounting bracket 3 to drive the synchronous reverse sliding of the two clamping plates 61.

[0035] An upper baffle assembly 7 is provided above the detector 5. As Figure 4As shown in the figure, the upper baffle assembly 7 includes an upper baffle 71 that can be lifted and lowered. When the upper baffle 71 descends, it can press the detector 5 tightly against the support plate 32, thereby further improving the stability of fixing the detector 5 and being more suitable for the bumps on the tunnel construction road surface. Moreover, the upper baffle 71 is provided with a plurality of through slots to avoid blocking the detector 5 from collecting gas data. In addition, the upper baffle 71 can shield and protect the upper part of the detector 5.

[0036] In this embodiment, the upper baffle 71 is slidably connected to the mounting frame 3 in the vertical direction. There are two second fixing plates 34 arranged vertically on the mounting frame 3. A third lead screw 72 is rotatably connected between the two second fixing plates 34. The third lead screw 72 passes through the upper baffle 71 along the vertical direction and is threadedly connected thereto. By setting a motor on one of the second fixing plates 34 to drive the third lead screw 72 to rotate, the lifting of the upper baffle 71 can be driven. And the lead angle of the third lead screw 72 is less than the equivalent friction angle (i.e., the third lead screw 72 is self-locking), ensuring that the position of the upper baffle 71 remains stable after adjustment.

[0037] In some embodiments, the upper baffle 71 can also be directly driven to lift by setting linear driving components such as telescopic rods and cylinders on the mounting frame 3.

[0038] A protective component 8 is arranged on the mounting frame 3, such as Figure 5 As shown, the protective component 8 includes a cylinder 82 fixed to the lower end of the support plate 32. A protective cover 81 is fixed on the driving shaft of the cylinder 82, and the cylinder 82 drives the protective cover 81 to lift. The upper end of the protective cover 81 is open, and a plurality of through slots are provided on the left and right side surfaces of the protective cover 81 and the outer side surface away from the mounting frame 3. Under the action of the cylinder 82, the protective cover 81 rises and can contact the upper baffle 71 to surround and protect the detector 5, avoiding interference and collision between the detector 5 and the tunnel wall or construction tools during multi-point detection. And the through slots on the protective cover 81 ensure that the detector 5 can detect the surrounding environmental data.

[0039] Working principle:

In addition, the through slots on the protective cover 81 ensure that the detector 5 can detect the surrounding environmental data.
