Description

Technical Field

[0001] This utility model relates to the field of indoor environmental monitoring technology, specifically a remote monitoring device for indoor environmental monitoring in power plants. Background Technology

[0002] In the power industry, sulfur hexafluoride (SF6) gas is an important medium used as an arc-quenching and insulating gas in enclosed medium and high-voltage switches. Under normal conditions, SF6 gas is non-toxic to humans. However, under the influence of a high-voltage electric arc, SF6 gas undergoes partial decomposition, and its decomposition products are often highly toxic; even trace amounts can be fatal. When leaks occur in indoor switches using SF6 gas as an insulating and arc-quenching medium, the leaked SF6 gas and its decomposition products accumulate in the lower levels of the room, causing localized oxygen deficiency and toxicity, posing a serious danger to the lives of personnel entering the room. Therefore, monitoring SF6 gas leaks in indoor environments of power plants, such as substations, is essential. This is why SF6 leak alarm monitoring systems are used to monitor gas leakage levels in indoor environments.

[0003] SF6 leak alarm monitoring systems include functions such as gas concentration detection, oxygen concentration detection, gas and oxygen concentration control, temperature and humidity detection, and audible and visual alarms. For example, patent publication number CN212008502U discloses an online alarm monitoring system for SF6 gas leaks, which includes a system host and an intelligent cloud. The system host is connected to a host computer, a fan controller, switch outputs, an external display screen, alarm lights, an SF6 O2 collector, and a temperature and humidity collector. The fan controller is connected to an exhaust fan. The host computer is connected to the Internet. The intelligent cloud is connected to a computer, a mobile application, a WeChat platform, and data backup.

[0004] However, the above-mentioned online alarm and monitoring device for SF6 gas leaks still has the following defects: the installation requirement for SF6 sensors is to install the sensors within 50cm of the ground. The existing installation distance is either based on worker experience or requires carrying additional measuring tools, which makes installation inconvenient. Utility Model Content

[0005] To address the shortcomings of existing technologies, this utility model provides a remote monitoring device for indoor environmental monitoring in power plants, making the installation of SF6 sensors more convenient.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a remote monitoring device for indoor environmental monitoring in power plants, comprising a sensor body and a fixed plate connected to the upper and lower ends of the sensor body, a protective plate connected to the outer wall of the sensor body, a measuring rod rotatably connected to the bottom of the protective plate, the measuring rod being 45-50 cm in length, an elastic structure connected to the fixed plate on the inner wall of the protective plate, and a ventilation groove provided on the protective plate.

[0007] Furthermore, the elastic structure includes two sleeves and two limiting rods, which are located on both sides of the sensor body. The two sleeves are fixedly connected to the inner wall of the protective plate. A sliding rod is slidably connected inside the sleeve, and a spring is sleeved on the outside of the sliding rod. One end of the spring is fixed to the sliding rod, and the other end is fixedly connected to the outside of the sleeve. Mounting blocks are fixedly connected to the outer ends of both fixed plates. The two sliding rods are slidably connected to the mounting blocks, and the two limiting rods are slidably connected to the bottom of the protective plate. After passing through the protective plate, the limiting rods are threadedly connected to the other two mounting blocks.

[0008] Furthermore, a slider is fixedly connected to the bottom of the slide rod, and the slider is slidably connected to the mounting block.

[0009] Furthermore, side L-plates are fixedly connected to both sides of the protective plate, and multiple rubber columns are fixedly connected to the inner wall of the side L-plates. One of the protective plates has a clearance groove.

[0010] Furthermore, a locking block is fixedly connected to the end of the measuring rod, and an elastic strip is fixedly connected to the outer end of the locking block. A slot for locking the locking block is opened on the outer wall of the protective plate, and an arc-shaped groove is opened on the inner wall of the slot. An elastic strip corresponding to the arc-shaped groove is fixedly connected to the outer wall of the locking block.

[0011] Furthermore, a U-shaped plug is inserted into the outer wall of the protective plate, and the U-shaped plug passes through the protective plate and engages with both sides of the vertical measuring rod.

[0012] Furthermore, the outer wall of the U-shaped plug is fixedly connected with a pull lug.

[0013] Compared with the prior art, the present invention has the following beneficial effects:

[0014] This invention features a protective plate on the outer wall of the sensor body, with a measuring rod installed at its bottom. The fixed length of the measuring rod ensures that the height of the sensor body from the ground is controlled within centimeters. The mounting plate is then connected to the mounting surface, accurately guaranteeing the sensor's installation distance. No additional measuring tools are required, simplifying the installation process and improving ease of operation. Furthermore, the measuring rod is rotatable and can be hidden within the protective plate for convenient storage. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] like Figures 1 to 6 As shown, a remote monitoring device for indoor environmental monitoring in a power plant includes a sensor body 1 and a fixed plate 2 connected to the upper and lower ends of the sensor body 1. A protective plate 4 is connected to the outer wall of the sensor body 1. A measuring rod 5 is rotatably connected to the bottom of the protective plate 4. The measuring rod 5 has a length of 45-50 cm. An elastic structure connected to the fixed plate 2 is connected to the inner wall of the protective plate 4. A ventilation groove 41 is provided on the protective plate 4.

[0024] like Figure 1 As shown, the remote monitoring device for indoor environmental monitoring in power plants in this utility model is structurally similar to an existing online alarm monitoring system for SF6 gas leaks, such as the SF6 gas leak online alarm monitoring system disclosed in patent CN212008502U. The main improvement of this utility model is that it makes the installation of the SF6 sensor more convenient. Figures 1 to 6As shown, the remote monitoring device for indoor environmental monitoring in power plants of this utility model requires the sensor body 1 to be installed before use. The protective plate 4 can be connected to the fixing plate 2 of the sensor body 1 through an elastic structure. After installation, the protective plate 4 is located on the outside of the sensor body 1. Then, the measuring rod 5 can be rotated to make the measuring rod 5 vertical. Since the length of the measuring rod 5 is between 45 and 50 cm, when the measuring rod 5 is vertical, its bottom surface is against the ground, so that the height of the sensor body 1 from the ground is within 50 cm. Then, the fixing plate 2 can be connected to the mounting surface, ensuring the installation distance of the sensor body 1 without the need to carry installation measuring tools.

[0025] It should be noted that the protective plate 4 should be made of a relatively rigid material to ensure good impact and kick protection. The ventilation slot 41 is designed to avoid interfering with the gas detection function of the sensor body 1.

[0026] like Figure 2 and Figure 3 As shown, the elastic structure includes two sleeves 6 and two limiting rods 8. The two sleeves 6 and the two limiting rods 8 are located on both sides of the sensor body 1. The two sleeves 6 are fixedly connected to the inner wall of the protective plate 4. A sliding rod 9 is slidably connected inside the sleeve 6. A spring 91 is sleeved on the outside of the sliding rod 9. One end of the spring 91 is fixed to the sliding rod 9, and the other end is fixedly connected to the outside of the sleeve 6. Mounting blocks 3 are fixedly connected to the outer sides of both ends of the two fixing plates 2. The two sliding rods 9 are slidably connected to the mounting blocks 3. The two limiting rods 8 are slidably connected to the bottom of the protective plate 4. After passing through the protective plate 4, the limiting rods 8 are threadedly connected to the other two mounting blocks 3.

[0027] Specifically, since the sensor body 1 is installed about 50 cm above the ground, pedestrians can easily kick the outer shell of the sensor body 1. Therefore, when the protective plate 4 is squeezed, the two sleeves 6 at the top of the protective plate 4 slide outside the slide rod 9, causing the spring 91 to compress. When the protective plate 4 is squeezed, the distance between the sleeves 6 and the slide rod 9 ensures that the protective plate 4 cannot contact the outer surface of the sensor body 1. At the same time, the lower end of the protective plate 4 will also slide outside the two limit rods 8. When the pedestrian finds that he has kicked the protective plate 4, he can back away. After the protective plate 4 is no longer squeezed, the spring 91 will cause the sleeves 6 to reset due to elastic potential energy, and continue to provide protection.

[0028] like Figure 2 and Figure 3 As shown, a slider 92 is fixedly connected to the bottom of the slide bar 9, and the slider 92 is slidably connected to the mounting block 3.

[0029] To facilitate the disassembly of the protective plate 4 from the sensor body 1, the two limiting rods 8 at the lower end of the protective plate 4 can be rotated to separate the two limiting rods 8 from the mounting block 3 on the fixed plate 2, and the limiting rods 8 can be disengaged from the protective plate 4. Then, the protective plate 4 can be lifted, which will drive the sleeve 6 and the slide rod 9 to move directly upward, so that the slider 92 can be disengaged from the mounting block 3. In this way, the protective plate 4 can be disassembled from the sensor body 1.

[0030] During installation, follow the reverse steps described above to complete the installation. When the protective plate 4 is damaged, the sleeve 6 can be detached from the protective plate 4. The sleeve 6 and the protective plate 4 can be detachably connected by screws to replace the protective plate 4, or replace the sleeve 6, slide rod 9 and spring 91.

[0031] like Figure 1 , Figure 2 and Figure 3 As shown, side L plates 7 are fixedly connected to both sides of the protective plate 4, and multiple rubber columns 72 are fixedly connected to the inner wall of the side L plates 7. One of the protective plates 4 has a clearance groove 71.

[0032] Specifically, in order to make the protective plate 4 have a good protective effect, the side L plates 7 on both sides are positioned on both sides of the protective plate 4 for protection. One of the protective plates 4 is provided with a clearance groove 71, which can facilitate the clearance of the existing terminal block technology, as shown in the figure.

[0033] like Figure 2 and Figure 4 As shown, a locking block 51 is fixedly connected to the end of the measuring rod 5, and an elastic strip 52 is fixedly connected to the outer end of the locking block 51. A slot 42 for locking the locking block 51 is opened on the outer wall of the protective plate 4. An arc groove 43 is opened on the inner wall of the slot 42. An elastic strip 52 corresponding to the arc groove 43 is fixedly connected to the outer wall of the locking block 51.

[0034] Specifically, when the measuring rod 5 is rotated and retracted, the locking block 51 can be inserted into the locking groove 42 inside the protective plate 4, and at the same time, the elastic strip 52 on the outside of the locking block 51 can be inserted into the arc-shaped groove 43, which makes it easy to fix the retracted measuring rod 5.

[0035] like Figure 2 and Figure 5 As shown, a U-shaped rod 11 is inserted into the outer wall of the protective plate 4. After passing through the protective plate 4, the U-shaped rod 11 is engaged with both sides of the vertical measuring rod 5.

[0036] Specifically, when the measuring rod 5 is rotated to the vertical position, the U-shaped plug 11 can be inserted into the protective plate 4. This allows the U-shaped plug 11 to be inserted into both sides of the measuring rod 5, ensuring that the measuring rod 5 is always fixed in a vertical position, which facilitates distance locking when the sensor body 1 is installed.

[0037] like Figure 5 As shown, a pull lug 10 is fixedly connected to the outer wall of the U-shaped plug 11. The pull lug 10 facilitates the pulling operation of the U-shaped plug 11.

[0038] 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.
