Description

Technical Field

[0001] This utility model relates to the field of pipeline monitoring battery installation technology, specifically an underground waterproof and heat-insulating electrical box. Background Technology

[0002] Video surveillance along oil and gas pipelines is primarily powered by solar energy and gel batteries.

[0003] On the one hand, the batteries are installed in insulated boxes, which are made of concrete. In actual projects, water often gets into the insulated boxes, causing the batteries to short-circuit and lose power.

[0004] On the other hand, in order to solve the problem of water entering the battery insulation box, in southern regions, the insulation box is often placed on the ground, which makes it easy to be stolen. Also, the temperature is too high, which can cause the battery inside the insulation box to overheat and affect the use of the battery. Utility Model Content

[0005] The purpose of this utility model is to provide an underground waterproof and heat-insulating electrical box, which solves the problem of waterproofing underground electrical boxes, ensures the working temperature of the batteries inside the electrical box, and guarantees the support strength of the box body located underground.

[0006] The objective of this utility model can be achieved through the following technical solutions:

[0007] An underground waterproof and heat-insulating electrical box includes a top cover and a box body with an opening at the top. A cable outlet is provided on one side of the box body. An outwardly protruding reinforcing rib is provided on the outer wall of the box body. The upper and lower end faces of the reinforcing rib are flush with the upper and lower end faces of the box body. An outwardly protruding support block is provided around the top cover. The support block is used to support the upper end face of the reinforcing rib. A sealing ring is connected between the top cover and the box body. A waterproof cable connector is sealed inside the cable outlet.

[0008] In a further embodiment, the upper part of the box is conical, and the lower part is frustum-shaped.

[0009] In a further embodiment, the surface where the support block abuts against the upper end of the reinforcing rib is an outwardly inclined slope.

[0010] In a further embodiment, the side of the upper cover that comes into contact with the box body is a conical surface.

[0011] In a further embodiment, the waterproof cable connector includes an O-ring and a flange, both of which have holes in their center for the cable to pass through. The flange is sealed to the outlet port by the O-ring.

[0012] In a further embodiment, the connection surface between the flange and the O-ring is coated with waterproof sealant.

[0013] In a further embodiment, a threaded post is provided at the end of the flange near the outlet, and the O-ring is fitted onto the threaded post. The O-ring is pressed and sealed between the flange and the outlet by the threaded post and the internal thread on the outlet.

[0014] In a further embodiment, both the flange and the cable connection surfaces are coated with waterproof sealant.

[0015] In a further embodiment, the waterproof and heat-insulating electrical box is buried underground with sand.

[0016] In a further embodiment, pads are provided on the bottom surface of the box.

[0017] The beneficial effects of this utility model are:

[0018] This utility model features a detachable top cover and housing, facilitating the placement of electrical equipment within the housing. Reinforcing ribs enhance the overall compressive strength of the housing, making it suitable for underground burial. Underground burial improves security and prevents theft. Furthermore, the constant underground temperature environment facilitates heat preservation, providing a stable and suitable operating temperature for the battery. Sealing rings and waterproof cable connectors ensure good waterproofing when used underground, preventing electrical accidents caused by water contact.

[0019] The support block increases the compressive strength of the cover and facilitates its transport. The support block has a sloping trapezoidal structure with a flat upper surface and a sloping lower surface, which allows for full contact with the upper surface of the reinforcing rib, preventing the box and the cover from not being tightly pressed together due to the contact between the support block and the reinforcing rib plate.

[0020] The reinforcing ribs increase the box's ability to withstand external impacts and prevent it from deforming under certain external forces.

[0021] Waterproof sealant can increase the seal between the flange and the cable, preventing water from seeping into the enclosure through the cable and causing electrical accidents. Attached Figure Description

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0027] like Figure 1 As shown, an underground waterproof and heat-insulating electrical box includes a top cover 1 and an open box body 2. A cable outlet 21 is provided on one side of the box body 2. An outwardly protruding reinforcing rib 22 is provided on the outer wall of the box body 2. The upper and lower end faces of the reinforcing rib 22 are flush with the upper and lower end faces of the box body 2. An outwardly protruding support block 11 is provided around the top cover 1. The support block 11 is used to support the upper end face of the reinforcing rib 22. A sealing ring 3 is connected between the top cover 1 and the box body 2. A waterproof cable connector 4 is sealed inside the cable outlet 21.

[0028] The working principle or implementation method is as follows: The box 2 is buried underground. Generally, the box 2 is about 1.8 meters high and 1 meter wide, allowing people to install electrical equipment inside. After connecting the cable at the waterproof cable connector 4, the cover 1 is placed on top. A sealing ring 3 is installed on the upper step inside the box 2. Then, the support block 11 of the cover 1 is aligned with the reinforcing rib 22 to cover the box 2. The box 2 is then buried in the ground. The support block 11 and reinforcing rib 22 increase the load-bearing capacity of the entire box 2 under the external soil. Burying it underground prevents the box 2 from being stolen and reduces the probability of damage. The shape of the reinforcing rib 22 can match the shape of the box 2, and the thickness can be around 8mm, depending on the depth of burial.

[0029] Based on the above working principle or implementation method, some implementation structures or embodiments are provided, wherein the upper part of the box 2 is conical and the lower part is frustoconical. This can improve its load-bearing capacity and also save materials.

[0030] The support block 11 has an outwardly inclined surface that abuts against the upper surface of the reinforcing rib 22. The side of the cover 1 that contacts the housing 2 is a tapered surface. The waterproof cable connector 4 includes an O-ring 41 and a flange 42. Both the flange 42 and the O-ring 41 have holes in their middle for the cable to pass through. The flange 42 is sealed to the outlet 21 by the O-ring 41. Waterproof putty 43 is applied to the connection surface between the flange 42 and the O-ring 41. A threaded post is provided at the end of the flange 42 near the outlet 21. The O-ring 41 is fitted onto the threaded post, and the O-ring 41 is pressed and sealed between the flange 42 and the outlet 21 by the threaded post and the internal thread on the outlet 21. Waterproof putty 43 is applied to both the flange 42 and the cable connection surface.

[0031] Pass the cable through the hole on the waterproof cable connector 4 and correctly install the O-ring 41. Finally, rotate the flange 42 to tightly engage the threaded post with the internal thread in the outlet 21, thus achieving a sealed and fixed waterproof interface. Throughout use, the tapered design of the top of the housing 2 effectively and quickly drains rainwater, preventing moisture accumulation; while the unique beveled design of the support block 11 disperses stress when subjected to external impacts, preventing excessive local stress that could lead to deformation or even breakage.

[0032] The waterproof and insulated electrical box is buried underground with sand. For example... Figure 2 As shown, a pad 5 is installed on the bottom surface of the enclosure 2. The pad 5 can increase the height of the electrical equipment inside the enclosure 2, further preventing the possibility of it being corroded by water leakage.

[0033] The enclosure 2 is made of high-strength stainless steel, with rust-proof treatment on both the inner and outer surfaces to enhance corrosion resistance. The tapered design between the top cover 1 and the enclosure 2 is not only aesthetically pleasing but also effectively guides water flow, preventing water accumulation. The support block 11 is made of lightweight alloy material, reducing overall weight while ensuring sufficient support. The O-ring 41 in the waterproof cable connector 4 is made of EPDM rubber, possessing good elasticity and weather resistance, maintaining a good sealing effect over a wide temperature range. The flange 42 is made of high-quality carbon steel with a galvanized surface treatment to increase corrosion resistance. The waterproof sealant 43 is made of high-performance polyurethane-based material, exhibiting excellent adhesion and sealing properties.
