Description

Technical Field

[0001] This utility model belongs to the field of gas detection technology, and more specifically, it relates to a fire prevention and early warning device for gas wells. Background Technology

[0002] Combustible gas detectors are a fundamental core component of the safety monitoring system in intelligent gas extraction. By collecting and transmitting combustible gas concentration data from the gas extraction well site in real time, they provide critical safety sensing inputs for the intelligent gas extraction system. They can not only provide automatic early warning of abnormal situations, but also coordinate and control gas extraction equipment (such as automatically shutting off valves and starting ventilation devices), ensuring fire safety during gas extraction. Existing combustible gas detectors generally consist of a housing, a sensor module, a signal processing module, and a display and alarm module.

[0003] Existing application number: CN202220486478.X, this utility model discloses a combustible gas alarm, including an alarm body and a warning light installed on its side wall. A top cover is provided above the alarm body, and the rear end of the top cover is hinged to the alarm body via a hinge structure. An elastic reset component is installed on the hinge structure. A temporary fixing component is provided between the bottom front end of the top cover and the alarm body. This utility model has a simple structure. The lower magnet and the upper magnet attract each other, using the attraction between them to adhere the top cover to the alarm body, shielding it from rain and improving its waterproof performance. When the lower magnet and the upper magnet separate, the return force of the torsion spring causes the top cover to rotate, opening the top cover and maintaining it in the open state.

[0004] Based on the above, when performing routine maintenance work such as fault diagnosis and parameter calibration, the front cover of the combustible gas detector needs to be removed from the front of the detector body. However, due to the possibility that workers may disassemble the front cover without disconnecting the power supply to the detector and while the equipment is still in operation monitoring the combustible gas concentration in the gas well, this not only poses a direct safety risk of electric shock to workers, but may also forcibly interrupt the detection process and damage the internal sensors due to the disassembly operation, making it impossible to continuously ensure the safety of the gas well site. Utility Model Content

[0005] To address the aforementioned technical problems, this utility model provides a fire prevention and early warning device for gas wells. This addresses the issue that existing combustible gas detectors require the front cover to be removed from the front of the detector body during routine maintenance such as fault diagnosis and parameter calibration. However, existing equipment may allow workers to illegally remove the front cover while the power supply is still on and the equipment is monitoring the combustible gas concentration in the gas well. This not only poses a direct risk of electric shock to workers but may also forcibly interrupt the detection process, damage internal sensors, and prevent the continuous assurance of safety at the gas well site.

[0006] The purpose and effectiveness of this utility model's fire prevention and early warning device for gas wells are achieved through the following specific technical means: A fire prevention and early warning device for gas wells includes a mounting base, a plug-in block, positioning holes, a detector body, a front cover, an anti-disassembly block, a quick-release assembly, and an anti-disassembly assembly. The plug-in block is inserted into the mounting base. Two positioning holes are provided, each located inside the plug-in block. The detector body is hinged to the front of the plug-in block. The front cover is fixedly connected to the front of the detector body. The anti-disassembly block has a square slot inside, and two anti-disassembly blocks are provided, each fixedly connected to the top of the front cover. The quick-release assembly is located at the rear of the detector body. The anti-disassembly assembly is located above the detector body.

[0007] Furthermore, the quick-release assembly includes: a sliding operating component and a connecting slider; the right end of the sliding operating component is slidably connected inside the mounting base; two connecting sliders are provided, and the two connecting sliders are slidably connected inside the mounting base respectively, with the left end of the upper connecting slider fixedly connected to the right side of the sliding operating component.

[0008] Furthermore, the quick-release assembly also includes: a transmission rack and a transmission gear; two transmission racks are provided, and the two transmission racks are respectively fixedly connected to the bottom of two connecting sliders; the transmission gear is rotatably connected inside the mounting base, and the transmission gear meshes with the two transmission racks respectively.

[0009] Furthermore, the quick-release assembly also includes: a spiral spring, a connecting post, and a positioning block; the inner end of the spiral spring is coaxially fixedly connected to the upper end of the transmission gear, and the outer end of the spiral spring is fixedly connected to the inside of the mounting base; two connecting posts are provided, and the upper ends of the two connecting posts are respectively fixedly connected to the lower outer ends of the two connecting sliders; two positioning blocks are provided, and the outer ends of the two positioning blocks are respectively fixedly connected to the lower part of the two connecting posts, and the two positioning blocks are respectively inserted into the two positioning holes.

[0010] Furthermore, the anti-tampering component includes: a fixed compartment, a metal sliding block, and a positioning element; the fixed compartment is fixedly connected to the top of the detector body; the metal sliding block is slidably connected inside the fixed compartment; the positioning element is fixedly connected to the lower front end of the metal sliding block, and the left and right ends of the positioning element are respectively inserted into the square slots of the two anti-tampering blocks.

[0011] Furthermore, the anti-tampering component also includes: a pull spring and an electromagnet; the bottom of the pull spring is fixedly connected to the top of the metal sliding block, and the top of the pull spring is fixedly connected to the inside of the fixing chamber; the electromagnet is fixedly connected to the top of the detector body, and the electromagnet is connected in series with the switching circuit of the detector body.

[0012] Compared with the prior art, the present invention has the following beneficial effects: First, the main body of the detector and the plug-in block are connected by a damped hinge, which can flexibly adjust the angle and hover stably according to the installation position, making it easy for staff to view the values ​​on the screen of the main body of the detector. The quick-release component setting allows the positioning block to be disengaged from the positioning hole simply by pulling the operating piece, and the main body of the detector can be quickly removed without removing the fixing bolts of the mounting base. This greatly simplifies the disassembly and assembly process, reduces maintenance time, and effectively improves the maintenance efficiency of gas well site equipment.

[0013] Secondly, by setting up anti-disassembly components, when the main body of the detector is powered on, the electromagnet is simultaneously powered on and magnetically attracts the metal sliding block, so that the positioning part is firmly locked into the slot of the anti-disassembly block. This structurally forces the removal of the front cover, completely avoiding the illegal operation of workers to remove the cover while it is powered on, effectively preventing the risk of electric shock, and maintaining the safety monitoring stability of the gas well site.

[0014] This utility model facilitates the viewing of screen values ​​by connecting the main body of the detector to the plug-in block with a damped hinge. Combined with a quick-release component, it simplifies the disassembly and assembly process to improve maintenance efficiency. At the same time, the anti-tamper component forcibly prevents the front cover from being removed when powered on, thus preventing the risk of electric shock to the staff. It provides good hardware support for building a reliable fire prevention and early warning system for gas well sites. Attached Figure Description

[0023] The embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are for illustrative purposes only and should not be construed as limiting the scope of this utility model.

[0024] Example 1: As attached Figure 1 To be continued Figure 7 As shown: This utility model provides a fire prevention and early warning device for gas wells, including a mounting base 1, a plug-in block 2, a positioning hole 201, a detector body 3, a front cover 4, an anti-disassembly block 10, and a quick-release assembly; the plug-in block 2 is inserted into the mounting base 1; two positioning holes 201 are provided, and the two positioning holes 201 are respectively provided inside the plug-in block 2; the detector body 3 is hinged to the front of the plug-in block 2; the front cover 4 is fixedly connected to the front of the detector body 3; a square slot is provided inside the anti-disassembly block 10, and two anti-disassembly blocks 10 are provided, and the two anti-disassembly blocks 10 are respectively fixedly connected to the top of the front cover 4; the quick-release assembly is located at the rear of the detector body 3.

[0025] The quick-release assembly includes: a sliding operating component 5 and a connecting slider 6; the right end of the sliding operating component 5 is slidably connected inside the mounting base 1; two connecting sliders 6 are provided, and the two connecting sliders 6 are slidably connected inside the mounting base 1 respectively, with the left end of the upper connecting slider 6 fixedly connected to the right side of the sliding operating component 5.

[0026] The quick-release assembly also includes: a transmission rack 601 and a transmission gear 7; two transmission racks 601 are provided, and the two transmission racks 601 are respectively fixedly connected to the bottom of the two connecting sliders 6; the transmission gear 7 is rotatably connected inside the mounting base 1, and the transmission gear 7 meshes with the two transmission racks 601 respectively.

[0027] The quick-release assembly also includes: a spiral spring 701, a connecting post 602, and a positioning block 603; the inner end of the spiral spring 701 is coaxially fixedly connected to the upper end of the transmission gear 7, and the outer end of the spiral spring 701 is fixedly connected to the inside of the mounting base 1; two connecting posts 602 are provided, and the upper ends of the two connecting posts 602 are respectively fixedly connected to the lower outer ends of the two connecting sliders 6; two positioning blocks 603 are provided, and the outer ends of the two positioning blocks 603 are respectively fixedly connected to the lower part of the two connecting posts 602, and the two positioning blocks 603 are respectively inserted into the two positioning holes 201.

[0028] The specific usage and function of this embodiment: During use, if it is necessary to view the values ​​on the screen inside the detector body 3, since the detector body 3 is hinged to the front of the plug-in block 2, the detector body 3 can be rotated and adjusted to a certain angle, making it convenient for the observer to view the values ​​on the screen of the detector body 3 installed at a high or low position. The hinge axis between the detector body 3 and the plug-in block 2 has damping, making it convenient for the detector body 3 to be suspended at a certain angle for viewing. The mounting base 1 is fixed to the wall with bolts. When it is necessary to disassemble the detector body 3, pull the sliding operating part 5 to the left, causing the transmission rack 601 of the connecting slider 6 above to move synchronously to the left. This is achieved through the transmission gear 7 and the two parts... Under the action of the gear and rack transmission mechanism formed by the meshing of the transmission rack 601, the connecting slider 6 below and the transmission rack 601 move synchronously to the right. Thus, driven by the connecting column 602, the two positioning blocks 603 are simultaneously pulled out from the two positioning holes 201. Then, the main body of the detector 3 is moved forward, and the plug-in block 2 can be taken out from the mounting base 1. After the maintenance is completed, the sliding operating part 5 is pulled to the left again to insert the plug-in block 2 into the mounting base 1. After releasing the sliding operating part 5, under the rebound action of the spiral spring 701, the two positioning blocks 603 are simultaneously inserted into the two positioning holes 201, so that the main body of the detector 3 is fixed in front of the mounting base 1 again.

[0029] Example 2: Based on Example 1, as shown in the appendix Figure 1 To be continued Figure 7 As shown, it also includes an anti-tamper component, which is located on top of the main body 3 of the detector.

[0030] The anti-tampering components include: a fixed compartment 8, a metal sliding block 9, and a positioning component 901; the fixed compartment 8 is fixedly connected to the top of the detector body 3; the metal sliding block 9 is slidably connected inside the fixed compartment 8; the positioning component 901 is fixedly connected to the lower front end of the metal sliding block 9, and the left and right ends of the positioning component 901 are respectively inserted into the square slots of the two anti-tampering blocks 10.

[0031] The anti-tampering components also include: a tension spring 902 and an electromagnet 11; the bottom of the tension spring 902 is fixedly connected to the metal sliding block 9, and the top of the tension spring 902 is fixedly connected to the inside of the fixed compartment 8; the electromagnet 11 is fixedly connected to the top of the detector body 3, and the electromagnet 11 is connected in series with the switching circuit of the detector body 3.

[0032] The specific usage and function of this embodiment are as follows: When the detector body 3 is in normal use, the detector body 3 is powered on, so that the electromagnet 11 generates a magnetic attraction to drive the metal sliding block 9 downward. The left and right ends of the positioning part 901 are respectively inserted into the square slots inside the two anti-tamper blocks 10, thereby preventing the detector body 3 from removing the front cover 4 forward while it is powered on, and preventing workers from violating operating procedures. When it is necessary to remove the front cover 4, the detector body 3 is first powered off. The electromagnet 11 loses its magnetic attraction to the metal sliding block 9. Under the rebound action of the tension spring 902, the metal sliding block 9 moves upward, and the left and right ends of the positioning part 901 are respectively disengaged from the square slots inside the two anti-tamper blocks 10. Only after this operation can the front cover 4 be removed from the front of the detector body 3.
