Description

Technical Field

[0001] This utility model relates to the field of gas detection technology, specifically a gas detection device for dismantling a gas holder. Background Technology

[0002] Gas detection refers to the process of qualitatively or quantitatively analyzing the type, concentration, or other characteristics of gases in the environment using specific technical means. It is widely used in fields such as industrial safety and environmental monitoring. A gas holder is a special pressure vessel used to store, buffer, and stabilize the supply of coal gas. Gas holder dismantling requires the use of gas detection devices to ensure construction safety. Gas detection devices are equipment that can detect the composition or concentration of specific gases in the environment.

[0003] Currently, gas detection devices still have certain shortcomings, such as the inability to quickly detect different areas, resulting in limited applicability.

[0004] To overcome the problem of detection devices being unable to detect gases quickly, a Chinese patent (publication number: CN212301500U) discloses a handheld gas detector. First, press and hold the power button for three seconds to turn on the handheld gas detector and turn on the LCD screen. Then, operate the control buttons to detect gases through the handheld gas detector. Finally, the gas is discharged through the outlet tube. It is simple to operate, highly portable, and can quickly detect gases in different areas, effectively reducing the limitations of its use.

[0005] However, the gas detection devices currently in use still have certain shortcomings. In the aforementioned document, the gas detection device can quickly detect different areas by venting the gas. However, when the device is carried by hand, the air tube swings and is relatively long, making it inconvenient to carry. Therefore, the existing structure needs to be improved.

[0006] The purpose of this utility model is to provide a gas detection device for dismantling a gas holder, so as to solve the problems mentioned in the background art, such as the inconvenience of carrying the gas detection device during the process and the inconvenience of fixing the detection device, which affects the detection effect.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a gas detection device for dismantling a gas holder, comprising an operating host, a connecting wire connected to the top of the operating host, and a detection head connected to the end of the connecting wire:

[0008] The operating host has a first movable block and a second movable block fixed on its side. The second movable block and the first movable block are symmetrically distributed about the operating host. The first movable block and the second movable block are each provided with a placement slot through their sides. The first movable block and the second movable block are respectively provided with a binding mechanism to limit the connection line inside their respective parts.

[0009] The operating host has a guide groove on its side near the first movable block, and a squeezing mechanism is provided inside the guide groove to facilitate the fixing of the detection device.

[0010] Furthermore, the restraint mechanism includes a T-shaped groove, which is formed on the side of the placement groove, and a T-shaped block slides through the inside of the T-shaped groove.

[0011] Furthermore, an arc-shaped block is fixed to the side of the T-shaped block, the arc-shaped block moves inside the placement groove, and a push rod is fixed to the top of the arc-shaped block.

[0012] Furthermore, a friction ring is connected to the surface of the push rod, the push rod slides inside the extrusion groove, the extrusion groove is opened on the side of the placement groove, and there are two extrusion grooves symmetrically connected about the center of the first movable block, and the friction ring is in close contact with the extrusion groove.

[0013] Furthermore, the extrusion mechanism includes a guide block that slides through the guide groove and is fixed to the sides of the first movable block and the second movable block respectively.

[0014] Furthermore, rubber pads are connected to the sides of the first and second movable blocks that are close to each other, and a reciprocating screw is rotatably connected through the inside of the guide groove, with a guide block threaded onto the surface of the reciprocating screw.

[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1, such as Figures 1-5The present invention provides the following technical solution to address the inconvenience of carrying a gas detection device: A restraint mechanism is disclosed, comprising an operating host 1, a connecting line 2 connected to the top of the operating host 1, and a detection head 3 connected to the end of the connecting line 2. A first movable block 101 and a second movable block 102 are fixed to the sides of the operating host 1, and the second movable block 102 and the first movable block 101 are symmetrically distributed about the operating host 1. Placement slots 103 are provided through the sides of both the first movable block 101 and the second movable block 102. Connection lines are respectively provided inside the first movable block 101 and the second movable block 102. 2. A limited binding mechanism, comprising a T-shaped groove 104, which is formed on the side of the placement groove 103. A T-shaped block 105 slides through the T-shaped groove 104. An arc-shaped block 106 is fixed to the side of the T-shaped block 105. The arc-shaped block 106 moves inside the placement groove 103. A push rod 107 is fixed to the top of the arc-shaped block 106. A friction ring 108 is connected to the surface of the push rod 107. The push rod 107 slides inside the extrusion groove 112. The extrusion groove 112 is formed on the side of the placement groove 103. There are two extrusion grooves 112 that are symmetrically connected about the center of the first movable block 101. The friction ring 108 is in close contact with the extrusion groove 112.

[0029] When the detection device is in use, after the operating host 1 is started, the gas in the external environment can be detected through the detection head 3. Before the gas holder is removed, the residual gas inside the holder can be detected, thereby ensuring the safety of the removal process. When the detection device is not in use, the connecting cable 2 is relatively long and inconvenient to carry. Therefore, the detection head 3 is bent and inserted into the side of the placement slot 103 of the operating host 1. The placement slot 103 of the operating host 1 has the same appearance as the detection head 3 and can be directly inserted into the placement slot 103. After the detection head 3 is inserted into the placement slot 103, it will not be exposed to the external environment, which can prevent dust from accumulating on the surface of the detection head 3. Then, the push rod 107 inside the first movable block 101 is rotated. When the push rod 107 is rotated, the friction ring 108 can squeeze the inner wall of the extrusion groove 112. The friction ring 108 can deform after being squeezed. When the friction ring 108 deforms, the push rod 107 can slide through the extrusion groove 112. At the same time, the push rod 107 The arc-shaped block 106 can be rotated, and when the arc-shaped block 106 rotates, it can drive the T-shaped block 105 to rotate. When the T-shaped block 105 rotates, it can rotate through the T-shaped groove 104. When the push rod 107 rotates into another extrusion groove 112, the friction ring 108 can be reset. When the friction ring 108 is reset, it can drive the push rod 107 to be positioned through friction. At this time, the push rod 107 can drive the arc-shaped block 106 to be positioned, and the arc-shaped block 106 can rotate to the other side to block the side of the detection head 3, thereby preventing the detection head 3 from moving out of the placement groove 103, thus achieving the positioning of the detection head 3. Then, the connecting line 2 is pressed into the placement groove 103 of the second movable block 102, and the placement groove 103 inside the second movable block 102 is rotated. In the same way, the arc-shaped block 106 inside the second movable block 102 positions the connecting line 2, thus achieving the positioning and binding of the connecting line 2 and the detection head 3 by the device, improving the convenience of carrying the detection device during use.

[0030] Example 2, as follows Figure 2 , Figure 3 and Figure 6 The present invention provides the following technical solution to address the problem that the detection device is inconvenient to fix and place, which affects the detection effect. Based on embodiment one, a squeezing mechanism is disclosed: A guide groove 109 is provided on the side of the operating host 1 near the first movable block 101. A squeezing mechanism for fixing the detection device is provided inside the guide groove 109. The squeezing mechanism includes a guide block 110, which slides through the guide groove 109. The guide block 110 is fixed to the sides of the first movable block 101 and the second movable block 102 respectively. Rubber pads are connected to the sides of the first movable block 101 and the second movable block 102 that are close to each other. A reciprocating screw 111 is rotatably connected through the guide groove 109. The guide block 110 is threadedly connected to the surface of the reciprocating screw 111.

[0031] During the dismantling of the gas holder, real-time monitoring of the working environment is required. To improve the efficiency and stability of fixing the main operating unit 1, a raised block or plate can be found. Then, the main operating unit 1 is moved to insert the gap between the first movable block 101 and the second movable block 102 into the surface of the raised block. The reciprocating screw 111 can be rotated through the guide groove 109. When the reciprocating screw 111 rotates, it can drive the two guide blocks 110 to slide threadedly. The threaded sliding directions of the two guide blocks 110 are opposite, and the guide blocks 110 can slide through the guide groove 109. When the first movable block 101 and the second movable block 102 slide, they can both drive the rubber pad to move. The rubber pad can increase the friction. When the rubber pad moves to the surface of the raised block, it can be squeezed and fixed. When the first movable block 101 and the second movable block 102 are squeezed and fixed, the main operating unit 1 can be fixed, which facilitates the fixed placement of the main operating unit 1 in real-time monitoring status and improves the ease of use of the monitoring device.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
