Description

Technical Field

[0001] This application relates to the field of electrical control technology, and in particular to a fire protection electrical control device. Background Technology

[0002] As shown in the patent document with publication number CN218183713U, the fire electrical control cabinet is a safety fire-fighting tool provided by the water pump manufacturer. Its main purpose is to protect the water pump motor from overvoltage, short circuit and overload. However, after long-term use, the air inside the cabinet will become humid, which will cause damage to the electrical components inside the cabinet. Therefore, the fire electrical control cabinet needs to be inspected and maintained regularly.

[0003] When inspecting and maintaining the fire electrical control cabinet, pulling the electrical component board causes the cabinet to squeeze the retaining ball, the spring to shorten, and the first slider to slide in the first groove. The retaining ball is then pulled out of the groove, thus removing the electrical component board from the cabinet and repairing the electrical components. However, since the electrical component board needs to be completely disassembled for repair, this process is not only cumbersome but also prone to damaging other electrical components.

[0004] Therefore, those skilled in the art have provided a fire protection electrical control device to solve the problems mentioned in the background art. Utility Model Content

[0005] In order to solve the problems mentioned in the background art, this application provides a fire protection electrical control device.

[0006] The fire protection electrical control device provided in this application adopts the following technical solution:

[0007] A fire protection electrical control device, comprising:

[0008] The fixing plate, and the protective housing on one side thereof;

[0009] The control mechanism is installed between the fixed plate and the protective housing, and includes a controller embedded inside the protective housing. Two junction boxes are installed on one side of the controller inside the protective housing. An electrical component body is installed on the fixed plate on one side of the protective housing. The junction boxes and the electrical component body are connected by wires. A disassembly assembly is installed on one side of the fixed plate for connecting the fixed plate to the protective housing.

[0010] By adopting the above technical solution, it is possible to control the electrical component body through the controller, and it is also convenient to connect the electrical component to the controller when it is installed.

[0011] Preferably, the disassembly and assembly assembly includes a sealing strip fixedly installed on one side of the fixing plate, mounting blocks installed on all four sides of the inner sidewall of the sealing strip, and an installation cavity opened between the mounting blocks and the sealing strip. A limiting block is slidably installed inside the installation cavity. One end of the limiting block passes through the sealing strip and extends to the outside of the sealing strip. A return spring is fixedly installed between the limiting block and the inner wall of the installation cavity. Limiting holes are opened on all four sides of the outer sidewall of the protective housing. The end of the limiting block located outside the sealing strip is inserted into the limiting hole.

[0012] By adopting the above technical solution, the protective shell can be easily disassembled and assembled, so as to expose the electrical components and facilitate subsequent inspection and maintenance by the staff.

[0013] Preferably, the control mechanism further includes drying components disposed on both sides of the protective housing. The drying components include ventilation housings connected to the bottom of both sides of the protective housing, and a dustproof plate is installed through one side of the ventilation housing.

[0014] By adopting the above technical solution, the air circulation inside the protective housing can be increased, so as to facilitate heat dissipation of the electrical components.

[0015] Preferably, a drawer is installed through the bottom of one side of the ventilation housing, and a desiccant is placed inside the drawer;

[0016] By adopting the above technical solution, moisture can be absorbed when air enters the interior of the protective housing, thus preventing excessive moisture inside the protective housing from damaging the electrical components.

[0017] Preferably, fixing bolts are installed around the perimeter of the surface of the fixing plate, and the fixing plate is fixedly connected to the external mounting point by the fixing bolts.

[0018] Preferably, the sealing strip is U-shaped and the material of the sealing strip is a rubber component;

[0019] By adopting the above technical solution, the sealing between the protective shell and the fixing plate can be improved, preventing rainwater from damaging the electrical components through the gap between them in rainy weather.

[0020] In summary, this application includes the following beneficial technical effects:

[0021] 1. This fire protection electrical control device, when inspecting and maintaining the electrical components, utilizes the cooperation between the disassembly and assembly components and the protective housing to facilitate the disassembly and assembly of the protective housing, so as to expose the electrical components as a whole. This makes it convenient for staff to inspect and maintain the electrical components. Furthermore, the snap-fit ​​design between the protective housing and the disassembly and assembly components allows for easy installation of the protective housing after maintenance, thus protecting the electrical components without having to remove the entire electrical components. This provides convenience for staff to inspect and maintain the electrical components and avoids damage to other electrical components when the entire electrical components are removed.

[0022] 2. This fire electrical control device utilizes a drying component, allowing external air to enter the interior of the protective housing through the dustproof plate, thereby removing heat from the interior of the protective housing and dissipating heat from the electrical components. As the external air passes through the interior of the ventilation housing, the desiccant inside the drawer absorbs moisture from the interior of the protective housing, thus reducing the humidity inside the protective housing.

[0028] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0029] This application discloses a fire protection electrical control device. (Refer to...) Figure 1-4 A fire protection electrical control device, comprising:

[0030] Fixed plate 1, and protective housing 2 provided on one side thereof;

[0031] The control mechanism 3 is installed between the fixed plate 1 and the protective housing 2, and includes a controller 31 embedded inside the protective housing 2. Two junction boxes 32 are installed on one side of the controller 31 inside the protective housing 2. An electrical component body 33 is installed on the fixed plate 1 on one side of the protective housing 2. The junction boxes 32 and the electrical component body 33 are connected by wires. A disassembly assembly 34 is installed on one side of the fixed plate 1 for connecting the fixed plate 1 to the protective housing 2.

[0032] Reference Figure 2 as well as Figure 3 The disassembly and assembly component 34 includes a sealing strip 341 fixedly installed on one side of the fixing plate 1. Mounting blocks 342 are installed around the inner sidewall of the sealing strip 341, and an installation cavity is opened between the mounting blocks 342 and the sealing strip 341. A limiting block 343 is slidably installed inside the installation cavity. One end of the limiting block 343 passes through the sealing strip 341 and extends to the outside of the sealing strip 341. A return spring 344 is fixedly installed between the limiting block 343 and the inner wall of the installation cavity. Limiting holes 345 are opened around the outer sidewall of the protective housing 2. The end of the limiting block 343 located outside the sealing strip 341 is inserted into the limiting hole 345.

[0033] In this embodiment, the limiting block 343 inside the limiting hole 345 is pressed to move, so as to separate the protective shell 2 from the fixing plate 1, so that the electrical component body 33 can be fully exposed, which is convenient for subsequent maintenance and repair. After the maintenance is completed, the protective shell 2 is simply clamped on the surface of the sealing strip 341 and continuously pushed inward, so that the protective shell 2 can squeeze the limiting block 343 when it moves, and push the limiting block 343 into the interior of the mounting cavity. When the limiting block 343 coincides with the limiting hole 345, the limiting block 343 is inserted into the interior of the limiting hole 345 by the elasticity of the return spring 344, and the installation is completed.

[0034] Please continue to refer to Figure 2 The sealing strip 341 is shaped like a square and is made of rubber.

[0035] In this embodiment, the sealing between the protective housing 2 and the fixing plate 1 can be improved, preventing rainwater from damaging the electrical component body 33 along the gap between the protective housing 2 and the fixing plate 1 on rainy days.

[0036] Reference Figure 1 , Figure 2 as well as Figure 4The control mechanism 3 also includes a drying assembly 35 disposed on both sides of the protective housing 2. The drying assembly 35 includes a ventilation housing 351 connected to the bottom of both sides of the protective housing 2. A dustproof plate 352 is installed through one side of the ventilation housing 351. A drawer 353 is installed through the bottom of one side of the ventilation housing 351. A desiccant 354 is placed inside the drawer 353.

[0037] In this embodiment, the airflow inside the protective housing 2 can be improved to facilitate heat dissipation of the electrical component body 33. When external air enters the interior of the protective housing 2, the desiccant 354 in the drawer 353 can absorb the moisture inside the protective housing 2 to avoid excessive moisture inside the protective housing 2.

[0038] Reference Figure 1 Fixing bolts 4 are installed around the perimeter of the surface of the fixing plate 1, and the fixing plate 1 is fixedly connected to the external mounting point by the fixing bolts 4.

[0039] In this embodiment, it is convenient for staff to install the device in a designated location for the purpose of controlling the fire protection facilities.

[0040] The implementation principle of a fire electrical control device according to an embodiment of this application is as follows: When the electrical component body 33 is being inspected, the limiting block 343 inside the limiting hole 345 is pressed to move, so as to separate the protective shell 2 from the fixing plate 1, so that the electrical component body 33 can be fully exposed, which is convenient for subsequent maintenance by the staff. After the inspection is completed, the protective shell 2 is simply clamped on the surface of the sealing strip 341 and continuously pushed inward, so that the protective shell 2 can squeeze the limiting block 343 when it moves, and push the limiting block 343 into the interior of the mounting cavity. When the limiting block 343 coincides with the limiting hole 345, the limiting block 343 is inserted into the interior of the limiting hole 345 by the elasticity of the return spring 344, and the installation is completed.

[0041] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
