Description

Technical Field

[0001] The utility model relates to the technical field of safety assessment, in particular to a production workshop safety assessment device. Background Art

[0002] With the rapid development of industry, dust explosion accidents are common, and there are more and more types of explosive dust. Dust mixed with air can form a flammable mixed gas. If it encounters an open flame or a high-temperature object, it is very easy to catch fire and complete the combustion process in an instant, releasing a large amount of heat energy, causing the combustion gas to rise suddenly and expand violently in volume, forming a very high expansion pressure, thus causing an explosion. Therefore, the dust environment safety in the workshop is extremely important and needs to be tested with a dust detector.

[0003] Some existing dust detectors use the principle of light absorption for detection. Dust will be blocked on the filter paper. At this time, the light beam passes through the filter paper and shines on the silicon photocell, causing the output current intensity of the silicon photocell to change. The dust concentration can then be accurately calculated through the calculation program set in the detector. This evaluation detection device requires regular replacement of the filter paper to ensure the accuracy of data measurement. The existing disassembly method requires opening the evaluation device and removing the filter paper from the inside. After the replacement is completed, the various parts are locked with screws. The whole process is relatively cumbersome, and if there are multiple evaluation devices, it will waste more time, resulting in affected evaluation efficiency. Utility Model Content

DETAILED DESCRIPTION

[0020] 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.

[0021] 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.

[0022] Embodiment 1

[0023] Reference Figure 1-3 A production workshop safety assessment device includes a fixed plate 1 and a dust detector 2 of the SGA-500 series. The dust detector 2 is fixedly connected to the top of the fixed plate 1. In order to ensure the accuracy of the safety assessment data, a plurality of assessment mechanisms 3 are connected to the bottom of the fixed plate 1 to prevent a single assessment mechanism 3 from being damaged and affecting the working process of the safety assessment. The assessment mechanism 3 is connected to a disassembly mechanism 4, which is located on the outside of the assessment mechanism 3 and is movably connected to the assessment mechanism 3. The assessment mechanism 3 can be quickly disassembled and assembled through the disassembly mechanism 4, thereby improving the disassembly and assembly efficiency of the device;

[0024] The disassembly and replacement mechanism 4 includes a hollow plate 41, a movable bottom plate 42 and a slider 43. The slider 43 is slidably connected to the fixed plate 1. The hollow plate 41 is fixedly connected to the fixed plate 1, and the interior of the hollow plate 41 is divided into two cavities, one of which is provided with a cylinder 44 fixedly connected to the bottom end of the movable bottom plate 42. The output end of the cylinder 44 is fixedly connected to a push rod 45, one end of the push rod 45 is clamped with the movable bottom plate 42, and the top of the movable bottom plate 42 is fixedly connected to a limit rod 46, which is slidably connected to the inner wall of another cavity, and a return spring 47 is fixedly connected between the top of the limit rod 46 and the top wall of the other cavity. In order to facilitate the synchronous disassembly and replacement of multiple evaluation mechanisms 3, a linkage assembly is arranged between adjacent movable bottom plates 42. In order to increase the friction between the push rod 45 and the inner wall of the hollow plate 41 and improve the stability of the push rod 45 during movement, a push rod 45 is arranged to be slidably connected to the inner wall of the hollow plate 41.

[0025] In the present embodiment, specifically, when a single evaluation mechanism 3 is to be replaced, the linkage assembly is opened, and then the slider 43 is moved to the evaluation mechanism 3 that needs to be replaced, and the cylinder 44 is started to push the push rod 45 downward, and one end of the push rod 45 is engaged with the movable bottom plate 42. The movement of the movable bottom plate 42 drives some parts of the evaluation mechanism 3 to move downward. When the parts of the evaluation mechanism 3 that need to be replaced are completely exposed, they can be replaced. After the replacement is completed, the movable bottom plate 42 is pulled back under the action of the reset spring 47, and the installation of the evaluation mechanism 3 is completed again. The whole process does not require screws, which is convenient and quick, and the cylinder 44 can slide with the slider 43, which has strong applicability and saves energy.

[0026] Embodiment 2

[0027] like Figure 1-3 As shown, this embodiment is basically the same as embodiment 1. Preferably, the evaluation mechanism 3 includes an outer cover 31, a silicon photocell 32, a filter paper 33 and a base 34. The top of the outer cover 31 is fixedly connected to the fixed plate 1, the silicon photocell 32 is detachably connected to the inner top wall of the outer cover 31, the base 34 is fixedly connected to the movable bottom plate 42, the filter paper 33 is detachably connected to the base 34, the filter paper 33 is located between the silicon photocell 32 and the inner wall of the outer cover 31, and the top of the filter paper 33 is seamlessly abutted against the inner top wall of the outer cover 31. In order to facilitate the alarm for the staff and maintenance personnel, a buzzer 21 is fixedly connected to the outer wall of the dust detector 2, and the silicon photocell 32 is electrically connected to the dust detector 2.

[0028] In this embodiment, specifically, when in use, dust will be blocked on the filter paper 33. At this time, the light beam passes through the filter paper 33 and irradiates the silicon photocell 32, causing the output current intensity of the silicon photocell 32 to change. Afterwards, the dust concentration can be accurately calculated by the calculation program set in the dust detector 2. When replacing, the movable bottom plate 42 drives the base 34 to move. When the base 34 completely pulls out the filter paper 33, the filter paper 33 can be replaced.

[0029] Embodiment 3

[0030] like Figure 1-3 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the linkage assembly includes a holder 421 and a lever 422. Two holders 421 are provided on the same movable bottom plate 42. The lever 422 is rotatably connected to the holder 421 and is spaced apart.

[0031] In this embodiment, specifically, when all the filter papers 33 need to be replaced, the clamping rod 422 is rotated to engage with the adjacent and closer clamping seat 421. When one movable bottom plate 42 moves downward, the remaining movable bottom plates 42 are driven to move synchronously, so that all the filter papers 33 are pulled out synchronously, which facilitates and quickly replaces the filter papers and improves work efficiency.

[0032] Embodiment 4

[0033] like Figure 1-3 As shown, this embodiment is basically the same as Embodiment 1. Preferably, the filter paper 33 is a circular ring structure, and the axial length of the filter paper 33 is less than the sum of the tensile limit lengths of the limiting rod 46 and the return spring 47.

[0034] In this embodiment, specifically, the axial length of the filter paper 33 and the setting of the stretching limit length of the limit rod 46 and the return spring 47 ensure that the filter paper 33 can be completely pulled out for replacement.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
