Description

Technical Field

[0001] This utility model relates to the field of gas monitoring technology, specifically to an urban gas safety monitoring device that is easy to maintain. Background Technology

[0002] Urban gas safety monitoring devices (hereinafter referred to as "gas monitoring devices") are mechanical-electronic composite systems installed at urban gas user terminals or key nodes of pipeline networks. These systems continuously monitor parameters such as combustible gas concentration, pressure, flow rate, temperature, and valve status, and promptly issue alarm signals, trigger gas supply cutoff, or activate ventilation when preset thresholds are reached. Their core objective is to prevent gas leaks, fires, and explosions, thereby ensuring urban public safety.

[0003] For example, Chinese patent CN222229936U discloses an urban gas safety monitoring device. Although the fixing plate is set inside the gas supply and distribution room, the main body of the safety monitoring device is snapped onto the outside of the mounting plate. The overall installation and disassembly are convenient, and maintenance and replacement are easy. Through the cooperation of the sliding column and the sliding groove, the mounting plate can slide on the sliding column. By adjusting the control of the component, the main body of the safety monitoring device can be installed in a suitable position on the sliding column, and thus the main body of the safety monitoring device can be installed at a suitable height in the gas supply and distribution room, thereby covering a wider area and making it easier to capture the distribution of gas.

[0004] However, this urban gas safety monitoring device has the following drawbacks: (1) The urban gas safety monitoring device has a weak position stability function after the monitoring height is adjusted. If the operator does not rotate the threaded rod in place, the mounting plate is easy to loosen and slide down, causing the monitoring height to be unstable. (2) The city gas safety monitoring device has weak dust prevention function. Since there is no dust prevention measure on the surface of the device after installation, dust is easy to accumulate on the surface after long-term use, causing the monitoring device to age, internal components to be damaged, and service life to be reduced.

[0005] Therefore, it is necessary to provide an easy-to-maintain urban gas safety monitoring device to solve the problems mentioned in the background art. Utility Model Content

[0006] To achieve the above objectives, this utility model provides the following technical solution: a city gas safety monitoring device that is easy to maintain, comprising: a base; An anti-slip assembly includes a fixed rod and a fixed frame. The fixed rod is fixed to the top of the base, and the fixed frame is slidably sleeved on the rod of the fixed rod. A plurality of limiting holes are evenly provided on the rod of the fixed rod along its extension direction. The anti-slip assembly is also provided with a locking component for locking the position of the fixed frame. The locking component cooperates with the limiting holes to lock the position of the fixed frame. A dustproof assembly includes a mounting plate, a monitoring body, and a dustproof plate. The mounting plate is fixed to one side of the fixed frame. The monitoring body is horizontally slidably mounted on the mounting plate. The dustproof plate is disposed above the monitoring body to protect the monitoring body and is detachably connected to the mounting plate.

[0007] Preferably, the locking component includes a fixing block, a sliding rod, and a spring. The sliding rod passes through the fixing frame and is inserted into the limiting hole. One end of the sliding rod is coaxially and fixedly connected to the fixing block, and the other end of the sliding rod is fixedly provided with a connecting plate. The spring is sleeved on the outside of the sliding rod and is fixedly connected to the connecting plate and the fixing block respectively.

[0008] Preferably, a pull rod is fixed to the side of the connecting plate opposite to the slide rod.

[0009] Preferably, the fixed frame has a fixed groove on the side near the slide rod, and the outer surface of the slide rod slides in contact with the inner wall of the fixed groove.

[0010] Preferably, the dustproof assembly further includes a mounting slider and an adjusting slider. The mounting plate has a horizontal mounting groove on the side opposite to the fixed frame. The mounting slider is slidably disposed in the mounting groove and fixedly connected to the monitoring body. The mounting plate has an adjusting groove on its top. The adjusting slider is slidably disposed in the adjusting groove. A support plate is fixed to the top of the adjusting slider. A dustproof plate is fixed to the bottom of the support plate on the side opposite to the adjusting slider for dust protection of the monitoring body.

[0011] Preferably, the dustproof plate is provided with an observation window, the position of which corresponds to the position of the monitoring body; a rectangular protective plate is fixedly connected to the bottom of the mounting plate on the side away from the monitoring body.

[0012] Preferably, there are two fixing frames, which are symmetrically distributed on both sides of the top of the base; the number of fixing rods is the same as that of the fixing frames, and the two are slidably connected in a one-to-one correspondence.

[0013] Compared with the prior art, this utility model provides an easy-to-maintain urban gas safety monitoring device, which has the following beneficial effects: 1. With the anti-slip component, when in use, pulling the lever causes the spring to extend and the slide bar to move. After sliding the fixed frame on the surface of the fixed bar to the appropriate position, the lever is released, and the spring rebounds, causing the fixed block to lock into the inside of the fixed bar, thus fixing the fixed frame and the monitoring body. This avoids the problem that the existing monitoring device is fixed in height and cannot adapt to pipeline scenarios of different heights. At the same time, the locking component prevents the fixed frame 202 from accidentally slipping, avoiding damage to the device or injury to pedestrians or gas pipelines.

[0014] 2. With the dustproof components in place, during use, slide the mounting slider until it fits into the mounting groove to ensure a stable connection between the monitoring unit and the mounting plate. Then, slide the adjusting slider in the adjusting groove to adjust the position of the support plate and the dustproof plate. The dustproof plate can prevent dust from entering the surface of the monitoring unit, and the observation window allows operators to easily observe the condition of the monitoring unit. This avoids the situation where the device has no dustproof measures after installation, and dust easily accumulates on the surface after long-term use, leading to aging of the monitoring unit, damage to internal components, and a reduced service life.

[0016] Please see Figure 1-4 This utility model provides an easy-to-maintain urban gas safety monitoring device, including: a base 1, made of cast iron; The anti-slip assembly 2 includes a fixing rod 201 and a fixing frame 202. The fixing rod 201 is fixed to the top of the base 1, and the fixing frame 202 is slidably sleeved on the rod of the fixing rod 201. A plurality of limiting holes are evenly provided on the rod of the fixing rod 201 along its extension direction. The anti-slip assembly 2 is also provided with a locking component for locking the position of the fixing frame 202. The locking component cooperates with the limiting holes to lock the position of the fixing frame 202. The dustproof component 3 includes a mounting plate 301, a monitoring body 304, and a dustproof plate 308. The mounting plate 301 is fixed to one side of the fixing frame 202. The monitoring body 304 is horizontally slidably mounted on the mounting plate 301. The dustproof plate 308 is disposed above the monitoring body 304 to protect the monitoring body 304 and is detachably connected to the mounting plate 301.

[0017] It should be explained that when the monitoring height needs to be adjusted (such as to adapt to the detection needs of gas pipelines of different heights), the locking component is used to release the locking between the fixed frame 202 and the fixed rod 201, and push the fixed frame 202 to slide along the fixed rod 201 to the target height. Then, the locking component is used to lock the fixed frame 202 with the limit hole. This avoids the problem that the existing monitoring device has a fixed height and cannot adapt to pipeline scenarios of different heights. At the same time, the locking component prevents the fixed frame 202 from accidentally slipping down, avoiding damage to the device or injury to pedestrians or gas pipelines.

[0018] Furthermore, during daily use, the dust cover 308 prevents dust from covering the monitoring unit 304; when the monitoring unit 304 needs maintenance, after removing the dust cover 308, the monitoring unit 304 can be pulled out horizontally along the mounting plate 301 without disassembling the entire mounting plate 301. This avoids the corrosion of the monitoring unit 304 by dust and rainwater in the urban environment, extending the equipment's lifespan.

[0019] Furthermore, the locking component includes a fixing block 203, a sliding rod 204, and a spring 205. The sliding rod 204 passes through the fixing frame 202 and is inserted into the limiting hole. One end of the sliding rod 204 is coaxially and fixedly connected to the fixing block 203, and the other end of the sliding rod 204 is fixedly provided with a connecting plate 206. The spring 205 is sleeved on the outside of the sliding rod 204 and is fixedly connected to the connecting plate 206 and the fixing block 203 respectively.

[0020] Furthermore, a pull rod 207 is fixedly provided on the side of the connecting plate 206 opposite to the slide rod 204.

[0021] It should be explained that when the maintenance personnel pull the lever 207 away from the fixed frame 202, the connecting plate 206 stretches the spring 205, and at the same time, the sliding rod 204 is pulled out from the limiting hole of the fixed rod 201. At this time, the fixed frame 202 can slide freely along the fixed rod 201. When it slides to the target height, the lever 207 is released, the spring 205 returns to its original deformation, and the lever 207 and the sliding rod 204 are reset. The sliding rod 204 is then reinserted into the limiting hole at the corresponding height, completing the locking of the fixed frame 202. The spring force of the spring 205 achieves the automatic reset and locking of the sliding rod 204, avoiding the cumbersome operation of turning the bolt multiple times. At the same time, the preload of the spring 205 can prevent the sliding rod 204 from dislodging from the limiting hole due to accidental vibration, improving the locking stability.

[0022] Furthermore, a fixing groove 4 is provided on the side of the fixing frame 202 near the slide rod 204, and the outer surface of the slide rod 204 slides in cooperation with the inner side wall of the fixing groove 4, so that the slide rod 204 can be inserted into the fixing frame 202.

[0023] Furthermore, the dustproof component 3 also includes a mounting slider 303 and an adjusting slider 306. The mounting plate 301 has a horizontal mounting groove 302 on the side away from the fixed frame 202. The mounting slider 303 is slidably disposed in the mounting groove 302 and is fixedly connected to the monitoring body 304. The top of the mounting plate 301 has an adjusting groove 305. The adjusting slider 306 is slidably disposed in the adjusting groove 305. A support plate 307 is fixed to the top of the adjusting slider 306. A dustproof plate 308 is fixed to the bottom of the support plate 307 on the side away from the adjusting slider 306 for dust protection of the monitoring body 304.

[0024] It should be explained that when the monitoring body 304 needs to be repaired, the adjusting slider 306 is pushed to slide along the adjusting groove 305 away from the monitoring body 304, which will move the dust cover 308 away; then the monitoring body 304 is pushed and pulled out horizontally along the mounting groove 302 by the mounting slider 303, which can expose the wiring terminals, sensor probes and other maintenance parts of the monitoring body 304, and then the monitoring body 304 can be repaired.

[0025] Furthermore, the dustproof plate 308 is provided with an observation window 309, the position of which corresponds to the position of the monitoring body 304, so as to protect the monitoring body 304 at the same time; a rectangular protective plate 5 is fixedly connected to the bottom of the mounting plate 301 on the side away from the monitoring body 304.

[0026] Furthermore, there are two fixing frames 202, which are symmetrically distributed on both sides of the top of the base 1; the number of fixing rods 201 is the same as that of the fixing frames 202, and the two are slidably connected in a one-to-one correspondence.

[0027] In practice, when the monitoring height needs to be adjusted, the locking component is used to release the locking between the fixed frame 202 and the fixed rod 201, and the fixed frame 202 is pushed to slide along the fixed rod 201 to the target height. Then, the locking component is used to lock the fixed frame 202 with the limit hole. This avoids the problem that the existing monitoring device has a fixed height and cannot adapt to pipeline scenarios of different heights. At the same time, the locking component prevents the fixed frame 202 from accidentally slipping down, avoiding damage to the device or injury to pedestrians or gas pipelines.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
