Description

Technical Field

[0001] The utility model belongs to the technical field of combustible gas detection, and particularly relates to a combustible gas auxiliary detection device. Background Technique

[0002] Combustible gas is a state of combustible substances, which refers to a gas that can be evenly mixed with air (or oxygen) within a certain concentration range to form a premixed gas, will explode when encountering a fire source, and releases a large amount of energy during the combustion process. Combustible gases will appear in the working conditions of many industries. Once these combustible gases exceed a certain concentration, large accidents such as explosions or fires may occur. Therefore, the state compulsorily requires that there must be devices for detecting combustible gases in places where combustible gases exist to ensure production safety.

[0003] For example, the Chinese patent with the publication number CN212255247U discloses a combustible gas auxiliary detection device, which can collect and detect the air in different areas of a room, effectively reducing the limitations of detection; it includes a box body, a partition board, a box door, a handle and a combustible gas sensor. A working cavity is arranged inside the box body. The partition board divides the working cavity into an upper cavity and a lower cavity. A power supply device and an information processing device are arranged in the lower cavity. The left half area at the top of the box body is communicated with an air inlet pipe, and an air suction fan is arranged on the air inlet pipe. The right half area at the top of the box body is longitudinally provided with an installation hole. The upper half area of the right side wall of the box body is communicated with an air outlet pipe. The left half area and the right half area on the front side wall of the box door are respectively provided with a display screen and multiple groups of buttons; it also includes a fixing plate, a cylinder body, a motor, a driving gear and a driven gear. The left half area at the top of the cylinder body is communicated with a branch pipe.

[0004] This patent has some disadvantages when in use. For example, the device is relatively large in size and cannot be applied to positions with relatively narrow working spaces. And only a single combustible gas sensor is arranged in this device. When the air at the detection location contains multiple combustible gases, this device cannot meet the detection requirements for different combustible gases. In view of this, we propose a combustible gas auxiliary detection device. Summary of the Invention

[0005] The purpose of the utility model is to provide a combustible gas auxiliary detection device to solve the problems raised in the above background technique.

[0006] In view of this, the utility model provides a combustible gas auxiliary detection device, including:

[0007] A housing, the housing has a spherical hollow structure. Fixing plates are symmetrically fixed in the inner cavity of the housing through bolts. A circuit board module and a power module are respectively installed on the two fixing plates. An audible and visual alarm is fixedly installed on the side wall of the housing;

[0008] Base, the base is fixedly installed directly below the housing. Symmetrical chutes are provided on the base. A round hole communicating with the two chutes is provided on the lower surface of the base. A sleeve is inserted into the round hole. A net cover is threadedly connected to the bottom end of the sleeve. A support plate is fixed in the inner cavity of the sleeve. A combustible gas sensor is installed on the support plate;

[0009] Two limiting components, the two limiting components are respectively located in the two chutes and are used to constrain and limit the corresponding sleeves;

[0010] Filtering component, the filtering component is located at the front opening of the housing and is used to filter the air around the housing and then suck it into the inner cavity of the housing;

[0011] Fixing component, the fixing component is located at the rear side of the housing and is used to fix the housing to the wall.

[0012] In this technical solution, the device has a small size and is provided with a fixing component, making the device easy to be fixedly installed at the detection location and facilitating the operator to install. In addition, by providing two sleeves and arranging combustible gas sensors in the inner cavities of the two sleeves, the two combustible gas sensors are set as any two of a gas sensor, a carbon monoxide sensor, a methane sensor, a hydrogen sensor, an acetylene sensor, an ammonia sensor, etc. that can detect all combustible gases, so that the device can detect and alarm different gases, greatly improving the applicability of the device and changing the limitation that traditional detection devices can only detect a single combustible gas.

[0013] In the above technical solution, further, the limiting component includes:

[0014] Partition board, the partition board is fixedly installed at the central position of the chute. Buttons slidably connected to the chute are symmetrically arranged on both sides of the partition board. Springs are fixed between the partition board and the two buttons. The bottom end of the button and the position located in the inner cavity of the sleeve are fixed with limiting blocks. Limiting holes for accommodating the insertion of the limiting blocks are provided on the circumferential side wall of the sleeve. The limiting blocks are inserted and matched with the limiting holes.

[0015] In this technical solution, by providing the limiting component and using the cooperation of the limiting block and the limiting hole, the sleeve can be fixed to the base. The operator only needs to press the two buttons inward to achieve the rapid installation and disassembly of the sleeve, greatly saving the replacement efficiency of the combustible gas sensor.

[0016] In the above technical solution, further, the filtering component includes:

[0017] The headgear is fixedly installed at the front opening of the housing. A first clamping groove is formed in the circumferential inner wall of the headgear, and a second clamping groove is formed at the front opening of the headgear. A blower is installed in the first clamping groove, and buffer gaskets are symmetrically arranged on the front and rear sides of the blower and located in the first clamping groove. A dust-proof net plate is installed in the second clamping groove, and an air inlet cover plate is fixed on the outer side of the dust-proof net plate in the second clamping groove.

[0018] In this technical solution, by setting the blower, the speed of air entering the inner cavity of the housing is accelerated. By setting the dust-proof net plate, dust in the outside air is prevented from entering the inner cavity of the housing, aging and damaging the electronic components inside the housing, thus improving the service life of this device.

[0019] In the above technical solution, further, the fixing assembly includes:

[0020] A fixing seat is arranged at the exact rear of the housing. T-shaped grooves are symmetrically formed in the fixing seat. T-shaped blocks are symmetrically fixed on the back side of the housing. The two T-shaped blocks are slidably matched with the corresponding T-shaped grooves. A patch glue is bonded to the back side of the fixing seat.

[0021] In this technical solution, by setting the fixing assembly, this device is convenient to be installed at the detection location.

[0022] In the above technical solution, further, a flip cover is rotatably connected to the upper surface of the fixing seat through a hinge.

[0023] In the above technical solution, further, the circuit board module, the power module, the sound and light alarm, the two combustible gas sensors, and the blower are electrically connected through wires.

[0024] In the above technical solution, further, the button and the limiting block are of an integrally formed structure.

[0025] In this technical solution, by setting the button and the limiting block as an integrally formed structure, the stability of the limiting assembly during operation is ensured.

[0026] The beneficial effects of the present utility model are:

[0027] 1. For this combustible gas auxiliary detection device, the device is small in size and is provided with a fixing assembly, making this device convenient to be fixedly installed at the detection location and facilitating the operator to install. During fixation, the operator only needs to bond and fix the fixing seat to the wall through the patch glue, and then align the two T-shaped blocks on the back side of the housing with the two T-shaped grooves and insert them downward. At this time, the housing is fixed to the fixing seat through the cooperation of the T-shaped blocks and the T-shaped grooves. The fixing method of this device is convenient, facilitating the user to install and fix this device.

[0028] 2. The combustible gas auxiliary detection device is provided with two sleeves, and combustible gas sensors are arranged in the inner cavities of both sleeves. The two combustible gas sensors are set as any two of a gas sensor, a carbon monoxide sensor, a methane sensor, a hydrogen sensor, an acetylene sensor, an ammonia sensor, etc., all of which can detect combustible gases.

[0046] Please refer to Figure 1 - Figure 10 As shown, this embodiment provides a combustible gas assisted detection device, including:

[0047] A housing 1, the housing 1 has a spherical hollow structure, and fixing plates 2 are symmetrically fixed in the inner cavity of the housing 1 by bolts. A circuit board module 3 and a power module 4 are respectively installed on the two fixing plates 2, and an audible and visual alarm 5 is fixedly installed on the side wall of the housing 1;

[0048] A base 6, the base 6 is fixedly installed directly below the housing 1. Sliding grooves 7 are symmetrically formed on the base 6, and a round hole communicating with the two sliding grooves 7 is formed on the lower surface of the base 6. A sleeve 8 is inserted into the round hole. A net cover 9 is threadedly connected to the bottom end of the sleeve 8, and a support plate 10 is fixed in the inner cavity of the sleeve 8. A combustible gas sensor 11 is installed on the support plate 10;

[0049] Two limiting components, the two limiting components are respectively located in the two sliding grooves 7 and are used for restricting and limiting the corresponding sleeves 8;

[0050] The filtering component is located at the front opening of the outer shell 1 and is used to filter the air on the peripheral side of the outer shell 1 and then suck it into the inner cavity of the outer shell 1;

[0051] The fixing component is located at the rear side of the outer shell 1 and is used to fix the outer shell 1 to the wall;

[0052] The circuit board module 3, the power module 4, the sound and light alarm 5, two combustible gas sensors 11 and the fan 20 are electrically connected by wires.

[0053] Among them, when the device is in use, first fix the fixing component to the wall at the detection position, then fix the outer shell 1 to the fixing component, and then start the device. The power module 4 provides power to meet the electrical energy requirements of the circuit board module 3, the sound and light alarm 5, two combustible gas sensors 11 and the fan 20 during operation. The filtering component works to suck the air on the peripheral side of the detection area into the inner cavity of the outer shell 1 and enter the inner cavities of the two sleeves 8. The combustible gas sensors 11 in the two sleeves 8 detect the gas. When the content of combustible gas in the air exceeds the standard, the combustible gas sensor 11 triggers a signal, which is processed by the circuit board module 3 and triggers the sound and light alarm 5, and the sound and light alarm 5 gives an audible and visual alarm; It is worth adding that the two combustible gas sensors 11 are set as any two of all combustible gas detectors such as gas sensors, carbon monoxide sensors, methane sensors, hydrogen sensors, acetylene sensors, ammonia sensors, etc.; When replacing the two combustible gas sensors 11, the operator only needs to press the two limiting components. At this time, the limiting components no longer limit the sleeve 8, and the operator can separate the sleeve 8 from the outer shell 1, then replace it with a suitable combustible gas sensor 11, and reset the sleeve 8.

[0054] The device is small in size and is provided with a fixing component, making the device easy to be fixedly installed at the detection location and convenient for the operator to install. In addition, by setting two sleeves 8 and arranging combustible gas sensors 11 in the inner cavities of the two sleeves 8, and setting the two combustible gas sensors 11 as any two of all combustible gas detectors such as gas sensors, carbon monoxide sensors, methane sensors, hydrogen sensors, acetylene sensors, ammonia sensors, etc., the device can detect and alarm different gases, greatly improving the applicability of the device and changing the limitation that traditional detection devices can only detect a single combustible gas. Embodiment

[0055] This embodiment provides a combustible gas auxiliary detection device. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The limiting component includes:

[0056] The partition plate 12 is fixedly installed at the central position of the sliding groove 7. Buttons 13 slidably connected to the sliding groove 7 are symmetrically arranged on both sides of the partition plate 12. Springs 14 are fixedly installed between the partition plate 12 and the two buttons 13. A limiting block 15 is fixed at the bottom end of the button 13 and located inside the sleeve 8. A limiting hole 16 for accommodating the insertion of the limiting block 15 is formed in the circumferential side wall of the sleeve 8. The limiting block 15 is inserted and matched with the limiting hole 16.

[0057] Among them, when it is necessary to disassemble the sleeve 8, the operator only needs to press the two buttons 13 inward. The two buttons 13 slide towards the center of the sliding groove 7 and compress the corresponding springs 14. At this time, the limiting blocks 15 below the two buttons 13 are separated from the limiting holes 16 on the sleeve 8. At this time, the operator can pull down the sleeve 8 or the mesh cover 9 with the other hand to separate the sleeve 8 from the base 6 and replace the combustible gas sensor 11 inside the sleeve 8. When installing the sleeve 8, first, the operator presses the two buttons 13 inward with one hand. Then, the operator aligns the top of the sleeve 8 with the round hole on the lower surface of the base 6 and inserts it upward into the round hole until the sleeve 8 is completely inserted. At this time, the lower end of the button 13 and the limiting block 15 are located in the upper part of the inner cavity of the sleeve 8. Then, the operator rotates the sleeve 8. When the two limiting holes 16 on the sleeve 8 rotate to the corresponding positions of the limiting blocks 15, under the elastic action of the spring 14, the button 13 moves outward, and at the same time, the limiting block 15 is inserted into the corresponding limiting hole 16 to restrict and position the sleeve 8.

[0058] By setting the limiting component and using the cooperation between the limiting block 15 and the limiting hole 16, the sleeve 8 can be fixed to the base 6. The operator only needs to press the two buttons 13 inward to quickly install and disassemble the sleeve 8, greatly saving the replacement efficiency of the combustible gas sensor 11. Embodiment

[0059] This embodiment provides a combustible gas auxiliary detection device. In addition to including the technical solutions of the above embodiments, it also has the following technical features. The filtering component includes:

[0060] A socket head 17 is fixedly installed at the front opening of the housing 1. A first clamping groove 18 is formed in the circumferential inner wall of the socket head 17. A second clamping groove 19 is formed in the front opening of the socket head 17. A fan 20 is installed in the first clamping groove 18. Buffer gaskets 21 are symmetrically arranged on the front and rear sides of the fan 20 and located in the first clamping groove 18. A dust-proof net plate 22 is installed in the second clamping groove 19. An air inlet cover plate 23 is fixed outside the dust-proof net plate 22 in the second clamping groove 19.

[0061] Among them, when the filtering component works, the fan 20 works and sucks the outside air into the inner cavity of the housing 1. In this process, the dust in the air can be blocked by the dust-proof net plate 22, and then the gas is discharged to the outside through the multiple pores on the two net covers 9.

[0062] By setting the fan 20, the speed of air entering the inner cavity of the housing 1 is accelerated. By setting the dust-proof net plate 22, it is avoided that the dust in the outside air enters the inner cavity of the housing 1 and causes aging and damage to the electronic components in the housing 1, thereby improving the service life of the device.

A patch glue 28 is bonded to the back side of the fixing seat 24;

[0065] The upper surface of the fixing seat 24 is rotatably connected with a flip cover 27 through a hinge.

[0066] Among them, when fixing this device, first, the fixing seat 24 is adhesively fixed to the wall through the patch glue 28. Then, the operator aligns the two T-shaped blocks 26 on the back side of the housing 1 with the two T-shaped grooves 25 and inserts them downward. At this time, the housing 1 is fixed to the fixing seat 24 through the cooperation of the T-shaped blocks 26 and the T-shaped grooves 25. After the fixing is completed, the flip cover 27 needs to be closed to prevent the outside dust from falling into the T-shaped grooves 25 from the upper opening of the T-shaped grooves 25.
