Hereinafter, embodiments will be described with reference to the drawings. The embodiments described below do not limit the contents of the invention described in the claims. The entire contents of the configurations shown in the following embodiments are not limited to those required as solutions of the inventions described in the claims.
Referring to fig. 1 to 3, fig. 1 is a front view of an electrical heating element energization protection device according to an embodiment of the present invention; FIG. 2 is a top view of an electrical heating element energization prevention apparatus provided in accordance with an embodiment of the present invention; FIG. 3 is a side view of an electrical heating element energization protection apparatus provided in an embodiment of the present invention.
The electric heating element electrifying protection device provided by the embodiment of the invention comprises a protective cover shell 101 and a door body.
The protective cover shell 101 is used for being installed on an electrifying station of the electric heating element, so that the electric heating element can enter the protective cover shell 101 when being positioned on the electrifying station, and two ends of the protective cover shell 101 are provided with openings for the electric heating element to enter and exit.
The door body is disposed at openings at two ends of the protective cover casing 101 and can be opened and closed, and the door body can be opened and closed in various manners, for example, the door body can be opened and closed in a rotating manner, and the door body can be opened and closed in a pushing and pulling manner. As long as can guarantee that the door body is when open state, can supply the electric heating element to pass in and out protection casing shell 101, when the door body is in the closed state, can block that the heat that electric heating element gived off leaks can.
The invention provides an electric heating element power-on protection device, wherein a protective cover shell 101 is arranged at an electric heating element power-on station, an electric heating element power-on plate carrying an electric heating element also enters the protective cover shell 101 when being conveyed to the electric heating element power-on station by a pipeline and powered on, two ends of the protective cover shell 101 are provided with door bodies capable of being opened and closed, and after the electric heating element power-on plate enters the protective cover shell 101, the door bodies are closed, so that a closed environment is formed inside the electric heating element power-on protection device, the influence of heat emitted when the electric heating element is powered on the environment temperature of a workshop is avoided, the electric heating element is also prevented from being in a high-temperature state when being powered on, and inflammable substances in the workshop are in contact with the electric.
In a specific embodiment of the present invention, the door body located at the inlet end of the shield casing 101 is an inlet door body 103, the door body located at the outlet end of the shield casing 101 is an outlet door body 104, and the inlet door body 103 and the outlet door body 104 may be door bodies having the same structure, so as to reduce the manufacturing cost.
The inlet door body 103 and the outlet door body 104 both include two door panels, and the two door panels are respectively hinged with two side walls of the protective cover casing 101, so that the inlet door body 103 and the outlet door body 104 are both split door bodies, and the passing in and out of the electric heating element energizing plate carrying the electric heating element conveyed by the pipeline body is facilitated.
In order to ensure that the door body can be automatically closed after the electric heating element electrifying plate enters the protective cover shell 101, in the embodiment, the door plate is hinged with the side wall of the protective cover shell 101 through the elastic hinge 102, and the inlet door body 103 and the outlet door body 104 are both in a closed state when the elastic hinge 102 is in a free state.
When an electric heating element electrifying plate carrying an electric heating element is conveyed to an electric heating element electrifying station by a pipeline body and is electrified, the electric heating element electrifying plate is firstly contacted with the inlet door body 103, the inlet door body 103 is gradually opened under the action of the pipeline body until the electric heating element electrifying plate completely enters the protective cover shell 101, the inlet door body 103 loses the blocking of the electric heating element electrifying plate, and is recovered to a closing state under the action of the elastic hinge 102, so that a closed environment is formed inside the electric heating element electrifying protective device. The invention can realize the process of automatically opening and closing the door without designing devices such as an automatic door, an inductive switch and the like, thereby reducing the manufacturing cost and the complexity of equipment and improving the reliability.
Further, the elastic hinge 102 is a limit elastic hinge, that is, the elastic hinge 102 has a locking function in a certain rotation direction, so that it can only rotate in one rotation direction.
The outward opening direction of the inlet door body 103 is locked, that is, the electric heating element electrifying plate can only enable the inlet door body 103 to enter the interior of the protective cover shell 101, but can not flow out of the protective cover shell 101 through the inlet door body 103; accordingly, the inward contraction direction of the outlet door body 104 is locked, that is, the electric heating element electrifying plate only can flow out of the interior of the protective cover shell 101 through the outlet door body 104 and can not enter the protective cover shell 101 through the outlet door body 104, thereby further increasing the safety.
In a specific embodiment of the present invention, the heights of the bottom of the door panels of the inlet door 103 and the outlet door 104 are both lower than the height of the electric heating element conducting plate on the pipeline, so that the impact on the inlet door 103 and the outlet door 104 is the electric heating element conducting plate, but not the electric heating element, and the electric heating element is not damaged.
In order to avoid the temperature inside the hood casing 101 from being too high, the top of the hood casing 101 is opened with a heat discharging hole 105, and part of the heat inside the hood casing 101 can be dissipated through the heat discharging hole 105 at the top. Further, in order to avoid the influence of heat emitted by the heat emission holes 105 on the operator, in the embodiment, the heat emission pipe is additionally communicated with the heat emission holes 105 and used for emitting heat to a predetermined position, and the operator can design the outlet position of the heat emission pipe according to the requirement so as to emit heat in the protective cover shell 101 to the corresponding position without influencing the working environment of the operator.
In order to avoid the situation that the appearance temperature of the protective cover shell 101 is too high and scalds people, the inner wall of the protective cover shell 101 is a steel plate coated with a heat insulation layer, so that the situation that impurities pollute the electric heating element cannot occur on the inner wall, and the outer wall of the protective cover shell 101 is in a normal temperature state due to the heat insulation layer, and the protective cover shell is safer.
The previous description of the disclosed embodiments is provided to enable any person skilled in the art to make or use the present invention. Various modifications to these embodiments will be readily apparent to those skilled in the art, and the generic principles defined herein may be applied to other embodiments without departing from the spirit or scope of the invention. Thus, the present invention is not intended to be limited to the embodiments shown herein but is to be accorded the widest scope consistent with the principles and novel features disclosed herein.
