Description

Technical Field

[0001] The utility model relates to the field of protective devices, in particular to an anti-siphon device for underground lamps. Background Art

[0002] In outdoor landscape lighting, the demand for underground lamps is also quite high. In the ground embedded installation environment, underground lamps often encounter problems because the construction workers do not perform standard wrapping and waterproofing on the cable joints in accordance with the specifications when connecting the external cables of the lamp products. Therefore, the water vapor in the soil will enter the lamp cavity through the cable in an inverted siphon manner, thereby causing damage to the lamp. In order to solve the problems mentioned in the above background, we propose an anti-siphon device for underground lamps. Utility Model Content

[0003] The utility model aims to provide an anti-siphon device for an underground lamp, which has the advantages of anti-siphon and heat dissipation.

[0004] The above technical purpose of the utility model is achieved through the following technical solutions: an anti-siphon device for an underground lamp, comprising a cavity, a cover plate is arranged on the top of the cavity, a boss is integrally processed on the bottom of the cover plate, the boss is threadedly connected to the cavity, a wiring seat is threadedly connected to the surface of the cavity, the interior of the cavity is filled with epoxy resin, a heat conduction plate is bolted to the interior of the cavity, and fins welded to the heat conduction plate are embedded in the bottom of the cavity.

[0005] By adopting the above technical scheme, the utility model installs a wiring seat on the surface of the cavity. After the external wiring and the wiring of the buried lamp are passed through the cavity, epoxy resin is poured into the cavity. The epoxy resin can seal the interior of the cavity to prevent external water vapor from entering, and ensure that water vapor in the soil layer will not enter the lamp cavity through the cable in an inverted siphon manner, thereby ensuring the service life of the lamp. By installing a heat conduction plate inside the cavity, the epoxy resin has the effect of absorbing heat. After the epoxy resin absorbs heat, it conducts the heat to the heat conduction plate, and then conducts the heat out of the cavity through the fins, thereby ensuring that the wiring joints will not cause wiring short circuits due to heat accumulation, thereby ensuring the normal use of the lamp.

[0006] The utility model is further configured as follows: a sealing pad is clamped inside the wiring seat, and the sealing pad is used in conjunction with the electric wire.

[0007] The above technical solution is adopted to facilitate sealing of the wiring seat and external wires.

[0008] The utility model is further configured as follows: a cross block is integrally processed on the top of the cover plate, and the cross block is used in cooperation with an outsider.

[0009] The above technical solution is adopted to facilitate twisting of the cover plate.

[0010] The utility model is further configured as follows: a fixing block is bolted on the surface of the cavity, and a hole groove is opened on the fixing block.

[0011] The above technical solution is adopted to facilitate fixed installation of the device.

[0012] The utility model is further configured as follows: a sealing groove is provided on the top of the cavity, and the sealing groove is used in conjunction with an external sealing ring.

[0013] The above technical solution is adopted to facilitate the placement of the external sealing ring.

[0014] The utility model is further configured as follows: a buckle seat is threadedly connected to the heat conducting plate through bolts, and the buckle seat is used in conjunction with an electric wire.

[0015] The above technical solution is adopted to facilitate the limiting and fixing of the electric wires.

[0016] The utility model is further configured as follows: the material of the cavity and the material of the cover plate are both polyurethane.

[0017] The above technical solution is adopted to improve the corrosion resistance of the cavity and the cover plate.

[0018] The utility model is further configured as follows: a ventilation groove is provided on the surface of the cavity.

[0019] The above technical solution is adopted to facilitate the contact between the fins and the external environment for heat dissipation.

[0020] In summary, the utility model has the following beneficial effects:

[0021] 1. The utility model installs a wiring seat on the surface of the cavity. After the external wiring and the wiring of the buried lamp are penetrated into the cavity, epoxy resin is poured into the cavity. The epoxy resin can seal the cavity to prevent external water vapor from entering, ensuring that soil layer water vapor will not enter the lamp cavity in a reverse siphon manner through the cable, thereby ensuring the service life of the lamp;

[0022] 2. The utility model installs a heat conducting plate inside the cavity. The epoxy resin has the effect of absorbing heat. After absorbing heat, the epoxy resin conducts the heat to the heat conducting plate, and then conducts the heat out of the cavity through the fins, thereby ensuring that the wiring joints will not cause short circuits due to heat accumulation, thereby ensuring the normal use of the lamp.
