DETAILED DESCRIPTION

[0024] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments so that those skilled in the art can better understand the present invention and implement it, but the embodiments are not intended to limit the present invention.

[0025] Embodiment 1

[0026] Reference Figure 1 , Figure 2 and Figure 3 As shown, the utility model is an alarm device for an electrostatic generator, the electrostatic generator includes a shell and wiring holes and screw holes arranged on the shell, including:

[0027] The cover 1 includes an internal cavity, and a notch 11 communicating with the cavity is opened on one side of the cover 1. The cover 1 is buckled on the housing through the notch 11 and covers the area where the wiring hole is located;

[0028] The smoke alarm 2 is arranged at the top of the cavity.

[0029] The utility model is used for the alarm device of the electrostatic generator. Its cover shell 1 can be easily buckled at a corner of the electrostatic generator shell through its own unique structure. A relatively closed space is formed between the cover shell 1 and the electrostatic generator and the wiring hole on the electrostatic generator shell is covered therein. When the wiring position of the electrostatic generator burns due to high temperature, the smoke generated by the burning will gather to the top of the cavity of the cover shell 1 through the wiring hole. After the smoke alarm 2 detects the smoke, it will sound an alarm to remind the staff to intervene in time, thereby avoiding the occurrence of fire and ensuring the safety of production equipment and production personnel.

[0030] Furthermore, the cover shell 1 includes a rectangular top plate 12, and the four sides of the top plate 12 are vertically connected with a first side plate 13, a second side plate 14, a third side plate 15 and a fourth side plate 16 connected end to end in sequence. The first side plate 13 and the second side plate 14 have the same height, the third side plate 15 and the fourth side plate 16 have the same height, and the height of the first side plate 13 or the second side plate 14 is less than the height of the third side plate 15 or the fourth side plate 16. An extension section 17 extending in its height direction is arranged in parallel on one side of the first side plate 13 away from the top plate 12, and the length of the extension section 17 is less than the length of the first side plate 13. The extension section 17 is connected to the fourth side plate 16 on one side thereof, and a fifth side plate 18 vertically connected to the third side plate 15 is arranged between the free end of the extension section 17 and the third side plate 15, and the height of the fifth side plate 18 is the same as the length of the extension section 17. Specifically, the first side plate 13 and the extension section 17 form an L-shaped structure, and the first side plate 13 and the extension section 17 can be an integrated structure. Specifically, the cover 1 has a special-shaped notch 11, and the edge of the notch 11 is adapted to the shape of the electrostatic generator housing, so that the cover 1 can be buckled at a corner of the electrostatic generator housing, which is easy to install, and a relatively closed internal space is formed between the cover 1 and the housing of the electrostatic generator, so that the smoke generated by the combustion can be gathered together, and the concentration that can be recognized by the smoke alarm 2 can be reached in a short time, so that an alarm can be issued in time.

[0031] Specifically, when the cover 1 is installed on the electrostatic generator 3, the third side plate 15 is parallel to and fits together with the side of the electrostatic generator housing with screw holes (set as the first side), the free end of the second side plate 14 abuts against the top surface of the housing (set as the second side), the free end of the fifth side plate 18 abuts against the side of the housing with wiring holes (set as the third side), and the L-shaped bayonet formed by the first side plate 13 and the extension section 17 is clamped on the edge between the second and third surfaces, and fits tightly with the second and third surfaces. The cover 1 can be stably buckled on the housing of the electrostatic generator through the limiting and matching between the surfaces, freeing the hands of the staff and facilitating the tightening work.

[0032] Furthermore, the smoke alarm 2 is connected to the middle of the top plate 12. It is conceivable that the smoke generated by the burning at the connection position of the electrostatic generator will drift upward and first gather at the top of the housing 1. Therefore, the smoke alarm 2 is arranged on the top plate 12, which is conducive to the smoke alarm 2 detecting the smoke and sounding the alarm in the first time.

[0033] Furthermore, a wire hole 161 is provided on the fourth side plate 16, and a wire rubber ring is provided in the wire hole 161. Specifically, when the cover 1 is installed on the electrostatic generator, the wire hole 161 corresponds to the position of the wiring hole on the electrostatic generator housing, and the connecting wire can be connected to the components inside the electrostatic generator through the wire hole 161 and the wiring hole in sequence. And according to the number and diameter of the connecting wires, a suitable wire rubber ring is provided on the wire hole 161, which can effectively reduce the smoke from escaping outward from the wire hole 161, which is conducive to the smoke alarm to detect the smoke in time.

[0034] Furthermore, the third side plate 15 is provided with a connection hole 151 for use with each screw hole, and the connection hole 151 is a waist-shaped hole. The cover of the alarm device can be fixed with the screw holes of the electrostatic generator itself, without drilling holes on the shell of the electrostatic generator, which reduces the installation difficulty and installation cost, and can avoid damage to the internal components of the electrostatic generator when drilling holes on the shell of the electrostatic generator, and maximize the original strength of the electrostatic generator.

[0035] Furthermore, an observation window is provided on the fourth side plate 16, and a cover plate covering the observation window is provided on the observation window, and the cover plate is made of a transparent material. The staff can identify the light alarm of the smoke alarm 2 through the cover plate (or the alarm sound of the smoke alarm 2), and can also check the working status of the smoke alarm 2 through the cover plate.

[0036] Furthermore, the top plate 12 is detachably connected to the first side plate 13, the second side plate 14, the third side plate 15 and the fourth side plate 16. The top plate 12 can be removed to facilitate the installation and replacement of the smoke alarm 2, but it is necessary to ensure that the connection position between the top plate 12 and the four side plates has a certain degree of sealing. More preferably, the top plate 12 can also be set as a flip structure so that the top plate 12 can be rotated around one side, thereby realizing the opening and closing of the top plate 12, which is convenient for the staff to operate.

[0037] Furthermore, sealing strips are provided at the positions where the cover 1 contacts the shell. The relatively soft sealing strips can play a buffering role when the cover 1 contacts the electrostatic generator to avoid damaging the electrostatic generator; and the sealing strips can also increase the friction between the cover and the electrostatic generator, so that after the staff buckles the cover 1 on the electrostatic generator, the cover 1 can be attached to the electrostatic generator more stably, which is convenient for the staff to screw on the screws.

[0038] Furthermore, the cover 1 is a sheet metal part.

[0039] Embodiment 2

[0040] The utility model also discloses an alarm system, comprising the alarm device for the static electricity generator as in the first embodiment.

[0041] Obviously, the above embodiments are merely examples for the purpose of clear explanation and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention of the utility model.
