Description

Technical Field

[0001] The utility model relates to the technical field of gas detection equipment, in particular to a gas detection device used in a power plant. Background Art

[0002] A thermal power plant is a factory that uses coal, oil and natural gas as fuel to produce electricity. The fuel burns in the boiler to heat water to make steam, converting the chemical energy of the fuel into thermal energy. The steam pressure drives the turbine to rotate, converting the thermal energy into mechanical energy. The turbine then drives the generator to rotate, converting the mechanical energy into electrical energy. The fuel combustion process in a thermal power plant will produce a large amount of harmful gases, among which carbon monoxide is the most special. It is a colorless, odorless, toxic gas that is harmful to human health.

[0003] Existing thermal power plants are equipped with detection probes at regular intervals to detect leaked carbon monoxide and other harmful gases to protect the personal safety of workers. However, due to the large internal space of the thermal power plants, carbon monoxide gas leaks and diffuses in an uneven manner. Often when the probe detects carbon monoxide, the leaked carbon monoxide already has a high concentration. The detection efficiency needs to be improved. Even if the probe detects carbon monoxide and the leak is repaired in time, the residual carbon monoxide in the air will affect people passing by and needs to be dealt with. Utility Model Content

[0004] The utility model discloses a gas detection device for a power plant, aiming to solve the technical problem that the working efficiency of existing carbon monoxide detection equipment needs to be improved.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0006] A gas detection device for a power plant comprises a straight rod support, a detection mechanism is installed at the bottom of the straight rod support; the detection mechanism comprises a casing distributed below the straight rod support, a connecting rod is rotatably installed inside the casing, the top of the connecting rod is connected to the straight rod support through a nut, a detection probe is installed at the bottom of the connecting rod, the detection probe is distributed inside the casing, a fan is rotatably installed inside the side end of the casing, a motor is installed at the top of the side end of the casing, a belt is connected between the output shaft of the motor and the fan, a first bevel gear is fixedly sleeved on the outer side of the top of the connecting rod, a second bevel gear is fixed to the output shaft end of the motor, and the first bevel gear and the second bevel gear are meshingly connected.

[0007] By providing a fan and a casing structure driven by a motor, the fan pushes the air toward the detection probe in a suction manner, and combined with the relative rotation of the casing, the carbon monoxide mixed in the air can be detected over a large range. The detection can be carried out in the first time and the staff can be notified, so that the staff can take protective measures in time, reduce the diffusion of carbon monoxide, and improve the working efficiency of the equipment in a roundabout way.

[0008] In a preferred solution, a filter is horizontally fixed to the side end of the casing, and the filter is an outwardly convex structure facing away from the casing.

[0009] By providing a filter and cooperating with the fan, large particles of impurities in the air are blocked, thereby protecting the detection probe, and the filter is set as an outward convex structure, so that impurities adhering to the filter cannot be firmly attached and fall off, further improving the use value of the filter.

[0010] In a preferred solution, an observation window is provided on the outer side of the housing, and the observation window is made of transparent glass material.

[0011] By providing a transparent observation window structure, it is convenient for users to observe the inside of the casing, thereby further improving the integrity of the operation of the device.

[0012] In a preferred solution, a catalyst box is slidably engaged inside the other end of the casing, a handle is fixedly mounted on the top of the catalyst box, a magnetic strip is fixed to the inner wall of the other end of the casing, and the magnetic strip and the side wall of the catalyst box are fixed by magnetic attraction.

[0013] By providing a catalytic box structure, carbon monoxide that enters the casing is preliminarily eliminated, thereby reducing the degree of danger for workers during on-site surveys, and the catalytic box is quickly installed by magnetic strips and magnetic attraction, which also improves the convenience of using the device.

[0014] As can be seen from the above, the gas detection device for power plants provided by the utility model has the following improvements and effects compared with the prior art:

[0015] First, we have set up a fan and casing structure driven by a motor. The fan pushes the air toward the detection probe by exhausting air, and combined with the relative rotation of the casing, we can detect carbon monoxide mixed in the air over a large range, ensuring that when carbon monoxide leaks at the beginning and the content is thin, it can be detected and the staff can be notified in the first time, so that the staff can take timely protection, reduce the diffusion of carbon monoxide, and improve the working efficiency of the equipment in a roundabout way.

[0016] Secondly, we have installed a catalytic box with a magnetic suction function to eliminate the carbon monoxide that enters the casing, reducing the amount of residual carbon monoxide, thereby reducing the degree of danger for workers during on-site surveys, and using a magnetic strip to quickly install the catalytic box, which also improves the convenience of using the equipment.

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0024] The gas detection device for a power plant disclosed in the utility model is mainly used in the scenario of carbon monoxide leakage detection in a thermal power plant.

[0025] Reference Figure 1 , Figure 2 , Figure 3and Figure 4 , a gas detection device for a power plant, comprising a straight rod support 1, a detection mechanism 2 is installed at the bottom of the straight rod support 1; the detection mechanism 2 comprises a casing 201 distributed below the straight rod support 1, a connecting rod 202 is rotatably installed inside the casing 201, the top of the connecting rod 202 is connected to the straight rod support 1 through a nut, a detection probe 203 is installed at the bottom of the connecting rod 202, the detection probe 203 is distributed inside the casing 201, a fan 204 is rotatably installed inside the side end of the casing 201, a motor 205 is installed at the top of the side end of the casing 201, a belt 206 is connected between the output shaft of the motor 205 and the fan 204, a first bevel gear 207 is fixedly sleeved on the outer side of the top of the connecting rod 202, a second bevel gear 208 is fixed to the output shaft end of the motor 205, and the first bevel gear 207 and the second bevel gear 208 are meshingly connected.

[0026] In this embodiment: the user installs the device to the specified position and starts the motor 205 at the same time. The motor 205 rotates, thereby driving the fan 204 to rotate through the belt 206. At the same time, the second bevel gear 208 located at the output end of the motor 205 will also push the first bevel gear 207, so that the housing 201 rotates around the connecting rod 202 as the center. The rotating fan 204 continuously pushes air into the interior of the housing 201. At the same time, the rotating housing 201 will drive the fan 204 to revolve around the connecting rod 202, thereby comprehensively gathering the air around the device and pushing it into the interior of the housing 201. The air will contact the detection probe 203 at the bottom of the connecting rod 202. Even if carbon monoxide has just begun to leak, the fan 204 can gather and push the thin carbon monoxide to the detection probe 203. The detection probe 203 detects the carbon monoxide and immediately issues an alarm to notify the security personnel.

[0027] It should be additionally explained that: the side end of the fan 204 is rotatably mounted on the support plate 11, and the support plate 11 is vertically fixed inside the housing (201).

[0028] Reference Figure 1 , Figure 2 and Figure 3 In a preferred embodiment, a filter screen 3 is horizontally fixed to the side end of the casing 201. The filter screen 3 is an outward convex structure facing away from the casing 201. Large particles of impurities contained in the air pushed into the inside of the casing 201 will be blocked by the filter screen 3, and the convex filter screen 3 will prevent the impurities from adhering and thus falling off. A magnetic card edge 9 is horizontally fixed to the side end of the filter screen 3. The magnetic card edge 9 is adsorbed inside the side end of the casing 201 to achieve quick installation of the filter screen 3.

[0029] Reference Figure 1 and Figure 2In a preferred embodiment, an observation window 4 is provided on the outer side of the housing 201 . The observation window 4 is made of transparent glass material. The user can see the internal operation of the device through the observation window 4 .

A magnetic strip 7 is fixed to the inner wall of the other end of the casing 201, and the magnetic strip 7 and the side wall of the catalyst box 5 are magnetically fixed; the user holds the handle 6 and pulls it hard to make the catalyst box 5 break away from the adsorption relationship with the magnetic strip 7 and move it out of the casing 201, and the carbon monoxide that enters the casing 201 through the connecting groove 10 will come into contact with the catalyst inside the catalyst box 5, thereby being removed.

[0031] Among them, it needs to be supplemented that: the catalyst used is a strontium-strong carbon monoxide catalyst, the active ingredient is manufactured by chemical synthesis, and alumina is used as a binder. The active ingredient content is as high as over 85%. The powder does not contain a binder and the active ingredient content is as high as over 99%.

[0032] Reference Figure 4 In a preferred embodiment, the top of the connecting rod 202 can also be connected to an L-rod bracket 8 through a nut. Through the arrangement of the L-rod bracket 8 and the straight rod bracket 1, the device can be freely installed in different positions.

[0033] Working principle: When in use, the user installs the device to the specified position and starts the motor 205 at the same time. The motor 205 rotates, thereby driving the fan 204 to rotate through the belt 206. At the same time, the second bevel gear 208 located at the output end of the motor 205 will also push the first bevel gear 207, so that the rotating fan 204 pushes the air into the interior of the casing 201. At the same time, the rotating casing 201 will drive the fan 204 to revolve around the connecting rod 202, thereby comprehensively gathering the air around the device and pushing it into the interior of the casing 201. The air will contact the detection probe 203 at the bottom of the connecting rod 202. The detection probe 203 detects carbon monoxide, thereby immediately sounding an alarm and notifying the security personnel.

[0034] The above is only a preferred specific implementation of the utility model, but the protection scope of the utility model is not limited to this. The replacement can be a replacement of part of the structure, device, method step, or a complete technical solution. Equivalent replacement or change based on the technical solution of the utility model and its utility model concept should be included in the protection scope of the utility model.
