Description

Technical Field

[0001] The utility model relates to a control cabinet, in particular to an electrical control cabinet used for non-negative pressure water supply equipment. Background Art

[0002] Non-negative pressure water supply equipment needs to be controlled by electrical equipment, which is generally an electrical control cabinet. The electrical control cabinet is the core component of industrial automation and electrical equipment control. It integrates power distribution, control, protection and monitoring functions in one, and is widely used in various industrial, commercial and civil facilities to ensure the safe and efficient operation of electrical equipment.

[0003] In the prior art, the Chinese patent CN2111019560U is a Chinese patent, and the patent name is an electrical control cabinet for non-negative pressure water supply equipment. The prior art adopts a rolling shutter device to avoid the situation where the electrical cabinet door is blocked. However, we found that the rolling shutter is controlled by a motor. If the motor is powered off, it needs to be opened manually. Manual opening and closing of the rolling shutter is relatively laborious, thus affecting daily use. Summary of the Invention

[0004] The utility model aims to solve the problem that the existing electric-controlled rolling shutter door needs manual operation when the power is off, which is laborious.

[0005] To achieve the above objectives, the present invention provides the following technical solutions:

[0006] An electrical control cabinet for non-negative pressure water supply equipment includes a cabinet body. The front side of the cabinet body is rotatably connected to a door assembly. The door assembly includes a rotating door piece and a rolling door piece. The rolling door piece is installed on the rotating door piece. One side of the rotating door piece is rotatably connected to the cabinet body through a hinge.

[0007] Preferably, air inlet bars are provided on both sides of the cabinet body near the bottom, a top ventilation slot is provided on the top of the cabinet body, and a fan assembly is provided inside the top ventilation slot.

[0008] Preferably: the fan assembly includes a fan housing and a fan body, the fan body is installed on the fan housing, a rubber positioning strip is provided on the side of the fan housing, and a positioning groove is provided on the inner wall of the top ventilation groove corresponding to the position of the rubber positioning strip, and the rubber positioning strip is movably connected to the inside of the positioning groove to fix the fan housing in the top ventilation groove.

[0009] Preferably, the surface of the fan housing is provided with limiting side ears above the cabinet body and is fitted on the top of the cabinet body.

[0010] Preferably, an inverted "V"-shaped cabinet top plate is provided on the top of the cabinet body through vertical support columns.

[0011] Compared with the prior art, the beneficial effects of the present invention are:

[0012] By setting up a door assembly, the door assembly includes a rotating door component and a rolling door component, so that the door opening operation can be performed according to actual conditions. When the rolling door cannot be used, the cabinet body can be opened by rotating the door component. The selection is made according to the usage situation, and the cabinet body can be opened by rotating the door component if the rolling door component has no power. This solves the problem that the existing electric rolling door needs to be manually operated when the power is cut off, which is more laborious.

[0013] By setting up a fan assembly, the fan assembly is embedded in the bottom ventilation groove, so that the modular design facilitates the replacement operation of the fan assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The technical solutions in the embodiments of the present invention will be described clearly and completely below with reference to the accompanying drawings in the embodiments of the present invention. Example

[0019] See also Figures 1 to 3 In the embodiment of the utility model, an electrical control cabinet for non-negative pressure water supply equipment includes a cabinet body 1, and the front of the cabinet body 1 is rotatably connected to a door assembly 2. The door assembly 2 includes a rotating door member 3 and a rolling door member 4. The rolling door member 4 is installed on the rotating door member 3. One side of the rotating door member 3 is rotatably connected to the cabinet body 1 through a hinge. The combination of the rotating door member 3 and the rolling door member 4 greatly improves the opening efficiency of the cabinet body 1. When the car is blocked in the position of the cabinet body 1, the cabinet body 1 is opened by the rolling door member 4. When the rolling door member 4 has no power and is difficult to open, the cabinet body 1 is opened by the rotating door member 3. The purpose of this combination is to facilitate the operation of opening the cabinet body 1 according to actual conditions, thereby greatly improving the opening efficiency of the cabinet body 1. Example

[0020] refer to Figure 2 and Figure 3 , air inlet bars 5 are provided on both sides of the cabinet 1 near the bottom, a top ventilation slot 6 is provided on the top of the cabinet 1, a fan assembly 7 is provided inside the top ventilation slot 6, the fan assembly 7 includes a fan housing 8 and a fan body 9, the fan body 9 is mounted on the fan housing 8, a rubber positioning strip 10 is provided on the side of the fan housing 8, a positioning slot 11 is provided on the inner wall of the top ventilation slot 6 corresponding to the position of the rubber positioning strip 10, the rubber positioning strip 10 is movably connected to the inside of the positioning slot 11 to fix the fan housing 8 in the top ventilation slot 6, which not only has a sealing effect, but also can The fan housing 8 is positioned to prevent the fan housing 8 from moving. The surface of the fan housing 8 is located above the cabinet 1 and is provided with a limiting side ear 12 that fits in the top of the cabinet 1. The purpose of the limiting side ear 12 is to limit the fan housing 8 to prevent the fan housing 8 from falling into the cabinet 1 when pressed. When removing it, directly move the limiting side ear 12 upward to drive the fan housing 8 to move upward. In this way, the upward movement of the fan housing 8 will drive the fan body 9 and the rubber positioning strip 10 to separate from the positioning groove 11, thereby removing the fan housing 8 and the fan body 9 together, making it convenient to replace and use them. Example
