Description

Technical Field

[0001] This utility model relates to the field of waterproof switchgear, specifically to a waterproof switchgear structure. Background Technology

[0002] The bottom of the switchgear typically features cable entry holes for incoming and outgoing cables, and the inner bottom of the switchgear is sealed with fire-retardant putty. However, some switchgear is used in cable trenches, where moisture levels are high. Poor sealing between the cable entry holes and the cables allows moisture to seep into the switchgear. This moisture, coming into contact with the cable compartment, can easily cause a fire. Furthermore, the moisture inside the switchgear can wet the fire-retardant putty, which, when heated by the temperature of the cable compartment, can crack and eventually detach. Therefore, a waterproof structure for the switchgear is needed to effectively seal the cable entry holes and cables, preventing moisture from entering the switchgear and mitigating the risk of the fire-retardant cracking and detaching. Utility Model Content

[0003] The purpose of this utility model is to provide a waterproof structure for switch cabinets.

[0004] To achieve this objective, the present invention adopts the following technical solution: A waterproof structure for a switch cabinet is provided for sealing the cable passage holes at the bottom of the switch cabinet body. The structure includes a tower-shaped sheath, with the inner edge of the cable passage hole on the outer edge of the tower-shaped sheath snapped in place. The incoming and outgoing cables pass through the middle of the tower-shaped sheath and are tightly fitted thereto.

[0005] Furthermore, an annular groove is provided on the bottom outer edge of the tower-shaped sheath, and the tower-shaped sheath is engaged with the wiring hole of the switch cabinet body through the annular groove.

[0006] Furthermore, the bottom of the annular slot has a sloping structure, and the bottom of the annular slot abuts against the bottom of the switch cabinet body.

[0007] Furthermore, the conical surface of the tower-shaped sheath is provided with several concentric grooves of progressively smaller diameter.

[0008] The beneficial effects of this utility model are: the waterproof structure of the switch cabinet seals the cable passage hole and the incoming and outgoing cables through the tower-shaped sheath, preventing moisture from entering the switch cabinet and avoiding the risk of the fireproof sealant cracking and falling off. Attached Figure Description

[0009] To more clearly illustrate the technical solutions of the embodiments of this utility model, the accompanying drawings used in the embodiments of this utility model will be briefly introduced below.

[0010] Figure 1 This is a schematic diagram of the installation state of this utility model; Figure 2A three-dimensional structural diagram for removing fireproof putty; Figure 3 This is a partial sectional view of the present invention; Figure 4 This is a cross-sectional view of the tower-shaped sheath; In the diagram: 1. Incoming and outgoing cables; 2. Tower-shaped sheath; 2a. Annular slot; 3. Fireproof putty; 4. Switch cabinet body; 4a. Cable passage hole. Detailed Implementation

[0011] The technical solution of this utility model will be further described below with reference to the accompanying drawings and specific embodiments.

[0012] The accompanying drawings are for illustrative purposes only and are schematic diagrams, not actual images. They should not be construed as limiting the scope of this patent. To better illustrate the embodiments of this utility model, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0013] Reference Figures 1 to 4 The diagram illustrates a waterproof structure for a switchgear, used to seal the cable passage hole 4a at the bottom of the switchgear body 4. It includes a tower-shaped sheath 2, with the outer edge of the tower-shaped sheath 2 interlocking with the inner edge of the cable passage hole 4a. The incoming / outgoing cables 1 pass through the middle of the tower-shaped sheath 2 and are tightly fitted therebetween. By providing the tower-shaped sheath 2, the gap between the incoming / outgoing cables 1 and the cable passage hole 4a is sealed, preventing moisture from the outside of the switchgear body 4 from entering the switchgear body 4. Furthermore, after sealing with the tower-shaped sheath 2, the fireproof sealant 3 will not crack or fall off, and moisture will not enter the switchgear and come into contact with the electrical components, ensuring equipment safety.

[0014] The bottom outer edge of the tower-shaped sheath 2 is provided with an annular groove 2a, and the tower-shaped sheath 2 is engaged with the cable passage hole 4a of the switch cabinet body 4 through the annular groove 2a. Through the action of the annular groove 2a, the cable passage hole 4a is wrapped by the tower-shaped sheath 2 from both the top and bottom, which plays a double protection role and prevents moisture from entering the cable chamber.

[0015] The bottom of the annular slot 2a is a sloping structure, and the bottom of the annular slot 2a abuts against the bottom of the switch cabinet body 4. Therefore, the thickness of the annular slot 2a cannot be perfectly fitted to the part to be engaged. Thus, the sloping structure ensures that the sloping area abuts against the switch cabinet body 4, guaranteeing a seal.

[0016] The conical surface of the tower-shaped sheath 2 has several concentric grooves with progressively smaller diameters. This groove structure prevents the top of the tower-shaped sheath 2 from deforming due to the grooves when the incoming and outgoing cables 1 are subjected to external impact, while keeping the bottom area immobile and avoiding seal failure.

[0017] The above are merely preferred embodiments of the present invention. It should be noted that those skilled in the art can make several improvements and modifications without departing from the technical principles of the present invention, and these improvements and modifications should also be considered within the scope of protection of the present invention.
