Description

Technical Field

[0001] The utility model relates to the technical field of gas leakage alarm devices, in particular to a gas leakage alarm device for gas engineering. Background Art

[0002] Gas engineering refers to all engineering activities related to urban gas supply, including the production, storage, transportation, distribution and use of gas. These projects are vital to the city's energy supply and residents' lives. During the use of gas, gas leak alarm devices are generally installed nearby to detect gas leaks in homes, commercial buildings or industrial environments. When the gas concentration is detected to exceed the safety threshold, these devices can emit sound and light alarms to remind people to take emergency measures, such as opening windows for ventilation, shutting off the gas source, etc., to prevent potential explosion or poisoning risks. They have been widely used.

[0003] Existing gas leak alarm devices are generally installed on the wall by bolts. When gas leaks, the gas content in the air increases. When the semiconductor sensor in the gas leak alarm device comes into contact with the gas, it will cause a change in resistance value. Gas leaks are detected by measuring the change in resistance value. When the threshold is exceeded, an alarm will be triggered. For gases lighter than air, such as natural gas and city gas, the alarm device is generally installed about 0.3 meters from the ceiling to increase the timeliness of its detection. However, since the alarm device is installed at a high position, when replacing the battery or performing maintenance, it is necessary to climb to a high place to remove it, which is inconvenient to operate. In order to solve this technical problem, the utility model proposes a gas leak alarm device for gas engineering. Utility Model Content

[0004] The main purpose of the utility model is to provide a gas leakage alarm device for gas engineering, which can effectively solve the problems mentioned in the background technology.

[0005] In order to achieve the above purpose, the technical solution adopted by the utility model is:

[0006] A gas leak alarm device for gas engineering includes a mounting plate, a connecting rod connected to the lower part of the mounting plate, a fixing plate connected to the lower end of the connecting rod, a sliding plate slidably connected to the front of the mounting plate and the connecting rod, a device body is provided inside the sliding plate, a sliding rod is provided on the back of the sliding plate, a locking mechanism is provided at the upper end of the sliding rod, a fixing mechanism is provided at the lower end of the sliding rod, and a blocking rod is installed at the upper end of the mounting plate.

[0007] Preferably, the locking mechanism includes a limiting rod, both ends of which are fixedly connected to the mounting plate, and a clamping block is fixedly connected to the outer surface of the sliding rod.

[0008] Preferably, the outer surface of the sliding rod is rotatably connected to a fixing ring, and one side of the fixing ring is fixedly connected to the sliding plate.

[0009] Preferably, the fixing mechanism includes a fixing box, one side of which is fixedly connected to the fixing plate, an inner wall of the fixing box is slidably connected to an insertion rod, and one end of the insertion rod is plugged into the bottom of the sliding rod.

[0011] Preferably, a spring is sleeved on the outer surface of the insertion rod, one end of the spring is fixedly connected to the retaining ring, and the other end of the spring is fixedly connected to the inner wall of the fixed box.

[0012] Compared with the prior art, the present invention has the following beneficial effects:

[0013] In the utility model, by providing components such as a connecting rod and a sliding rod, the restriction of the sliding rod is first released by a fixing mechanism, and the sliding rod is rotated so that the sliding rod can slide downward, and the sliding rod drives the sliding plate to move downward, thereby driving the device body to move downward, so that the device body moves to a height that is convenient for people to pick up, achieving the effect of easy installation and disassembly, and no need for the aid of a ladder or the like for installation and disassembly, thereby solving the problem that the alarm device is installed at a high position and it is necessary to climb to a high place to remove it when replacing batteries or performing maintenance, which is inconvenient to operate.

[0014] In the utility model, by providing components such as a locking mechanism and a fixing mechanism, the pull plate can be pulled to drive the insertion rod to move toward the outside of the fixing box, so that the insertion rod is pulled out from the sliding rod and no longer restricts the sliding rod. When the socket on the sliding rod moves to the insertion rod, the spring gives the insertion rod an extrusion force close to the sliding rod, so that it can be automatically inserted into the interior of the sliding rod and stuck, so as to achieve a quick fixing effect. The sliding rod drives the card block to rotate 90 degrees, so that the limit rod no longer restricts the card block, thereby achieving the effect of facilitating the fixing of the upper and lower positions of the sliding rod.

[0021] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific implementation methods.

[0022] like Figure 1-5 As shown, a gas leakage alarm device for gas engineering includes a mounting plate 1, the lower part of the mounting plate 1 is connected to a connecting rod 2, the lower end of the connecting rod 2 is connected to a fixed plate 3, the front of the mounting plate 1 and the connecting rod 2 is slidably connected to a sliding plate 4, a sliding mechanism 10 is provided between the connecting rod 2 and the sliding plate 4, the sliding mechanism 10 includes a T-shaped plate 1001 and a slide groove 1002, the T-shaped plate 1001 is installed on the sliding plate 4, the slide groove 1002 is opened inside the connecting rod 2 and the mounting plate 1, by making the T-shaped plate 1001 stuck in the slide groove 1002, so as to facilitate the sliding of the sliding plate 4 on the connecting rod 2, and prevent the sliding plate 4 from separating from the connecting rod 2. According to needs, other sliding methods can also be used, such as guide rails and rollers, as long as the sliding and inseparable effects can be achieved.

[0023] The sliding plate 4 is provided with a device body 5 inside, and a limiting mechanism 11 is provided between the sliding plate 4 and the device body 5. The limiting mechanism 11 includes a limiting plate 1101 and a limiting groove 1102. The limiting plate 1101 is installed on both sides of the device body 5, and the limiting groove 1102 is opened on the sliding plate 4. By making the limiting plate 1101 stuck in the limiting groove 1102, the device body 5 is prevented from being separated from the sliding plate 4 in the horizontal direction, so that the device body 5 can only slide upward from the sliding plate 4. In normal use, the upper part of the device body 5 is blocked by the blocking rod 8, thereby fixing the device body 5. When the device body 5 moves to the lower part, the device body 5 can be directly lifted upward for quick disassembly and installation. The limiting mechanism 11 can also use other methods to limit the device body 5.

[0024] The back of the sliding plate 4 is provided with a sliding rod 6, and the upper end of the sliding rod 6 is provided with a locking mechanism 7. The locking mechanism 7 includes a limit rod 701, both ends of the limit rod 701 are fixedly connected to the mounting plate 1, and the outer surface of the sliding rod 6 is fixedly connected with a clamping block 702. The sliding rod 6 can drive the clamping block 702 to rotate. When the clamping block 702 rotates between multiple limit rods 701, the clamping block 702 can be restricted by the limit rod 701 to prevent the clamping block 702 from moving up and down, thereby fixing the height of the sliding rod 6. The outer surface of the sliding rod 6 is rotatably connected with a fixing ring 703, and one side of the fixing ring 703 is fixedly connected to the sliding plate 4. The sliding rod 6 is connected to the sliding plate 4 through the fixing ring 703, so that they move up and down synchronously, but do not affect the rotation of the sliding rod 6.

[0025] The lower end of the sliding rod 6 is provided with a fixing mechanism 9, which includes a fixing box 901. One side of the fixing box 901 is fixedly connected to the fixing plate 3. The inner wall of the fixing box 901 is slidably connected with a plug rod 902. One end of the plug rod 902 is plugged into the bottom of the sliding rod 6. By inserting the plug rod 902 into the interior of the sliding rod 6, the sliding rod 6 can be stuck to prevent it from rotating. After the plug rod 902 is pulled out from the sliding rod 6, the sliding rod 6 can rotate. The outer surface of the plug rod 902 is fixedly connected with a retaining ring 903. The end of the plug rod 902 is installed with a pull plate 905. By pulling the pull plate 905, the plug rod 9 can be driven 02 moves toward the outside of the fixed box 901, thereby pulling the insertion rod 902 out of the sliding rod 6. A spring 904 is sleeved on the outer surface of the insertion rod 902, one end of the spring 904 is fixedly connected to the retaining ring 903, and the other end of the spring 904 is fixedly connected to the inner wall of the fixed box 901. The spring 904 gives the retaining ring 903 a force close to the sliding rod 6, thereby giving the insertion rod 902 an extrusion force close to the sliding rod 6. When the socket on the sliding rod 6 moves to the insertion rod 902, it can be automatically inserted into the inside of the sliding rod 6 and stuck. A grip 12 is also provided at the bottom of the sliding rod 6 to facilitate gripping and rotation.

[0026] A baffle 8 is installed at the upper end of the mounting plate 1. Bolt holes are provided on the mounting plate 1 and the fixed plate 3, which can be fixed to the wall by bolts. The sliding plate 4 can slide on the mounting plate 1 and the connecting rod 2 to facilitate height adjustment. When in use, the bottom of the device body 5 is supported by the sliding plate 4, and its top is in contact with the baffle 8, thereby increasing the stability of the device body 5 to prevent the device body 5 from moving up and down during early use.

[0027] It should be noted that in actual use of the device, when the device body 5 needs to be repaired or the battery needs to be replaced, the pull plate 905 is first pulled to drive the insertion rod 902 to move to the outside of the fixed box 901, so that the insertion rod 902 is pulled out from the sliding rod 6, and the sliding rod 6 is no longer restricted. The sliding rod 6 is rotated to make the sliding rod 6 drive the block 702 to rotate 90 degrees, so that the limit rod 701 no longer restricts the block 702, and the sliding rod 6 is slid downward. The sliding rod 6 drives the sliding plate 4 to move downward through the fixing ring 703, thereby driving the device to move downward. The main body 5 is moved downward to a height at which the device body 5 is easily accessible by hand, and then the device body 5 is slid upward from the sliding plate 4 to disassemble the device body 5, thereby achieving the effect of easy disassembly. Similarly, when installing, the device body 5 is placed on top, and the sliding rod 6 is pushed upward to reset the device body 5, and then the sliding rod 6 is rotated to lock the sliding plate 4 so that the locking mechanism 7 is locked. The fixing mechanism 9 fixes the rotation angle of the sliding rod 6, thereby achieving the effect of easy installation and disassembly, and no ladder or the like is required for installation and disassembly.

[0028] When the sliding rod 6 rotates to the top and rotates back, when the socket on the sliding rod 6 moves to the insertion rod 902, the spring 904 gives the retaining ring 903 a force close to the sliding rod 6, thereby giving the insertion rod 902 an extrusion force close to the sliding rod 6, which can automatically be inserted into the inside of the sliding rod 6 and stuck, so as to achieve a quick fixing effect.
