Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of chemical experimental equipment, and specifically relates to a grounding protection device for an electric heating mantle. Background Art
[0002] In the daily operation of a central chemical laboratory, as a key component of a condensation reflux device, the stability and safety of an electric heating mantle are directly related to the smooth progress of an experiment and the safety of operators. However, for the crucial link of grounding protection of the electric heating mantle, a series of challenges are currently faced, especially in the context where it is not convenient to carry out grounding protection, and the problem is particularly prominent.
[0003] Since the condensation reflux device relies on relatively low-temperature tap water for cooling during operation, this causes condensed water to easily form on the outside of the device due to the temperature difference. Under rainy and humid weather conditions, the condensed water phenomenon is more significant. If the condensation device cannot be kept dry in a timely and effective manner, the accumulated condensed water may seep into the interior of the electric heating mantle. Once the internal circuit and components of the electric heating mantle come into contact with water, it is extremely easy to cause a short circuit or electric leakage, which not only damages the equipment but also may pose a safety hazard to the laboratory environment. Summary of the Utility Model

Specific embodiments
[0026] The following will further describe in detail the specific embodiments of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.
[0027] Embodiment 1:
[0028] As Figures 1-7As shown in the figure, an electric heating sleeve grounding protection device includes a machine shell 1, an electric heating sleeve 2 arranged on the machine shell 1, a grounding sound and light alarm 3 arranged on the machine shell 1 for giving an alarm when the electric heating sleeve 2 is short-circuited, a main body 4 of a condensation reflux device placed on the electric heating sleeve 2, a pair of clamping cylinders 5 arranged on the machine shell 1 for clamping and fixing the main body of the condensation loop device, and a wiping mechanism 6 arranged on the machine shell 1 for wiping the water droplets attached to the outside of the main body 4 of the condensation reflux device. The wiping mechanism 6 includes a wiping placement block 61, a sponge block 62 arranged in the wiping placement block 61, a driving mechanism 7 for driving the wiping placement block 61 to move up and down in the vertical direction, and a linkage mechanism 8 for driving the wiping placement block 61 to tilt and squeeze the sponge block 62 to drain water. A placement groove 611 for placing the sponge block 62 is formed on the wiping placement block 61.
[0029] First, place the main body 4 of the condensation reflux device on the electric heating sleeve 2. Then, a pair of clamping cylinders 5 are activated to clamp and fix the main body 4 of the condensation reflux device. When the electric heating sleeve 2 is short-circuited, such as in cases of poor contact, broken wire, or abnormal increase in resistance, the grounding sound and light alarm 3 is activated. Through bright flashes and loud alarm sounds, it immediately attracts the attention of the operator, clearly indicating that the electric heating sleeve is currently in an unsafe state. This prompts the user to immediately stop using the device and take corresponding measures for troubleshooting or repair, effectively preventing electrical accidents that may be caused by poor grounding and ensuring the safety of personnel and equipment. During the heating process of the electric heating sleeve 2, water droplets will adhere to the main body 4 of the condensation reflux device. When it is necessary to wipe the attached water droplets, first, through the driving mechanism 7, drive a pair of wiping placement blocks 61 and sponge blocks 62 to move up or down in the vertical direction along the attached condensation reflux device. During this process, the sponge block 62 will wipe and clean the water droplets attached to the attached condensation reflux device, thereby preventing water droplets from adhering to the main body 4 of the condensation reflux device and dripping onto the electric heating sleeve 2, which may cause the electric heating sleeve 2 to short-circuit. During the process of the wiping placement block 61 and the sponge block 62 moving downward, the linkage mechanism 8 can squeeze out the water from the sponge block 62 that has adsorbed water droplets, driving the sponge block 62 to always remain dry and reducing the replacement frequency of the sponge block 62.
[0030] Such as Figures 2-4 As shown in the figure, the driving mechanism 7 includes a first linear driver 71, a threaded rod 72, a sliding block 73, and a limiting block 74. The first linear driver 71 is arranged on the machine shell 1. The input end of the threaded rod 72 is installed on the output end of the first linear driver 71 through a coupling. The sliding block 73 is slidably arranged in the vertical direction on the sliding block 73 and is threadedly connected to the sliding block 73. The sliding block 73 is fixedly connected to the wiping placement block 61. The limiting block 74 is arranged on the machine shell 1 and there are a pair of them. The limiting block 74 is in clearance fit with the sliding block 73.
[0031] When it is necessary to wipe the water droplets on the outer wall of the main body 4 of the condensation reflux device, first, the first linear driver 71 is started, and then the threaded rod 72 is driven to rotate. When the threaded rod 72 rotates, the slider 73 threadedly connected to the threaded rod 72 can be driven to descend vertically along the limiting block 74. During this process, the slider 73 can drive the wiping placement block 61 fixedly connected thereto and the sponge block 62 in the wiping placement block 61 to wipe the water droplets on the outer wall of the attached condensation reflux device main body 4, achieving the automatic wiping of the water droplets attached to the outer wall of the condensation loop device main body by the sponge block 62, keeping the outer wall of the condensation reflux device main body 4 dry, and preventing the water droplets from falling on the electric heating sleeve 2 and causing the electric heating sleeve 2 to short-circuit.
[0032] As Figures 4-6 shown, the linkage mechanism 8 includes a rotating rod 81, a gear 82, and a rack 83; the rotating rod 81 is rotatably arranged on the casing 1 and there are a pair of them; the rack 83 is arranged on the rotating rod 81 and is fixedly coaxial with the rotating rod 81; the rack 83 is arranged on the slider 73 and there are a pair of them, and the rack 83 meshes with the gear 82.
[0033] When the wiping placement block 61 and the sponge block 62 descend through the slider 73 to the position in contact with the electric heating sleeve 2, during this process, the slider 73 can drive the rack 83 to descend synchronously in the vertical direction. During the descent of the rack 83, the engaged gear 82 can be driven to rotate. When the gear 82 rotates, the rotating rod 81 fixedly coaxial with it can be driven to rotate synchronously, achieving the conversion of the vertical sliding of the rack 83 into the rotational movement of the gear 82.
[0034] As Figure 5 and Figure 6 shown, the linkage mechanism 8 further includes a connecting rod 84 and a pressing block 85; the connecting rod 84 is arranged on the rotating rod 81 and is fixedly coaxial with the rotating rod 81; the pressing block 85 is arranged on the connecting rod 84 and is used to press the sponge block 62, and the pressing block 85 is in a semi-circular shape that fits the sponge block 62 more closely.
[0035] When the gear 82 rotates, it can drive the connecting rod 84 and the extrusion block 85 fixed coaxially with the rotating rod 81 to make an inclined swing close to the sponge block 62 until the extrusion block 85 fits and squeezes the sponge block 62. At this time, the water adsorbed in the sponge block 62 can be squeezed out. When the sliding block 73 descends to contact the electric heating sleeve 2, the sponge block 62 can be automatically and obliquely contacted and squeezed by the gear 82 and the extrusion block 85, and the water adsorbed in the sponge block 62 can be squeezed out, so as to keep the sponge block 62 dry at all times, enabling the sponge block 62 to continuously wipe the water droplets adhering to the outer wall of the main body 4 of the condensation reflux device. When the sliding block 73 ascends, it can drive the gear 82 to rotate and the extrusion block 85 to reset, so that the extrusion block 85 automatically returns to its initial position.
[0036] As Figures 4-6 shown, the linkage mechanism 8 further includes a drainage groove 86 and a collection box 87; the drainage groove 86 is opened on the sliding block 73; the collection box 87 is arranged on the casing 1 and there are a pair of them. The collection box 87 is used to collect the water discharged from the drainage groove 86.
[0037] When the sponge block 62 is squeezed by the extrusion block 85, the water adsorbed by the sponge block 62 can be discharged through the drainage groove 86 opened on the sliding block 73, and flow out of the wiping placement block 61 and the sliding block 73. Finally, the squeezed water can flow into the collection box 87, achieving automatic recovery of the water squeezed out of the sponge block 62 and preventing water from accumulating in the wiping placement block 61.
[0038] Embodiment 2:
[0039] Compared with Embodiment 1, as Figures 5-7 shown, the linkage mechanism 8 further includes a guiding and restricting rod 88; there are a pair of guiding and restricting rods 88 arranged on the casing 1. The guiding and restricting rod 88 has a clearance fit with the rack 83. The guiding and restricting rod 88 is used to restrict the rack 83 from rising or falling in the vertical direction. When the sliding block 73 drives the rack 83 to move downward in the vertical direction, the rack 83 can stably rise or fall in the vertical direction along the guiding and restricting rod 88 with which it has a clearance fit. The setting of the guiding and restricting rod 88 can make the sliding of the rack 83 more stable.
[0040] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art in this technical field, without departing from the technical principle of the present invention, several improvements and refinements can still be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
