Description

Technical Field

[0001] The invention relates to the technical field of electrical safety explosion-proof technology, and in particular to a split-type explosion-proof isolation sealing box and a detection method. Background Art

[0002] Explosion-proof isolation sealed boxes are generally used in places where flammable and explosive hazardous chemicals are produced, used or stored. Places with explosion-proof requirements not only require explosion-proof electrical equipment, but also require the laying of electrical lines through galvanized steel pipes. At the joints of the electrical lines, explosion-proof isolation sealed junction boxes are required.

[0003] At present, during the explosion-proof electrical installation construction process, the explosion-proof isolation sealing box is installed, and the wiring cables of the explosion-proof electrical equipment are also completed. That is, the explosion-proof isolation sealing box needs to be laid and installed in advance. If an isolation sealing box needs to be added somewhere in the later stage, all the cables need to be pulled out and then rewired. This will result in a large amount of work, which is time-consuming and labor-intensive and will also affect the quality of the cable wiring. Summary of the invention

[0004] The present invention aims to avoid the shortcomings of the prior art and provides a split-type explosion-proof isolation sealing box.

[0005] The present invention solves the technical problem by adopting the following technical scheme: a split-type explosion-proof isolation sealing box, comprising two detachable half-box bodies, the two half-box bodies are connected to form a sealed box body, a space for accommodating cables is provided in the sealed box body, a filler inlet tube is connected to one of the half-box bodies, the filler inlet tube is used for injecting filler, and the filler is used to fill the gap between the inside of the sealed box body and the cable.

[0006] In several embodiments, the filler inlet pipe is obliquely arranged on the outer end surface of the half box body, and a sealing member is detachably provided at one end of the filler inlet pipe.

[0007] In several embodiments, a connection end is respectively provided at both ends of the sealed box body, and a connector is detachably provided on the connection end. The cable passes through the sealed box body from one connector and passes through the other connector to the outside of the sealed box body.

[0008] In several embodiments, the filler is an adhesive.

[0009] In several embodiments, the two half box bodies are locked and connected via a locking member.

[0010] In several embodiments, the sealing box body is square in shape, and the connecting end is tubular in shape.

[0011] In several embodiments, the inner diameter of the connection end at the side where the included angle between the sealing box body and the filler inlet pipe is smaller than the inner diameter of the sealing box body.

[0012] The beneficial effects of the present invention are:

[0013] The present invention uses a detachable sealing box body structure, which can facilitate the rapid installation of the sealing box at a newly added position after the cable is laid, without the need to re-lay the cable, thereby improving construction efficiency and reducing construction costs.

[0014] The present invention provides a filler inlet through the filler inlet tube structure, and tightly fills and wraps the internal cables to achieve isolation and explosion-proof.

[0015] The present invention seals the internal space structure of the box body to facilitate the entry and flow of fillers and perform gap-free filling. BRIEF DESCRIPTION OF THE DRAWINGS

[0020] Below, embodiments of the present invention are described in detail with reference to the accompanying drawings. To make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0021] Therefore, the following detailed description of the embodiments of the present invention provided in conjunction with the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. All other embodiments obtained by ordinary technicians in the field based on the embodiments of the present invention without making any creative work are within the scope of protection of the present invention.

[0022] Example 1

[0023] like Figure 1-Figure 3As shown, the present embodiment provides a split-type explosion-proof isolation sealing box, comprising two detachable half-box bodies 11, the two half-box bodies 11 are connected to form a sealing box body 10, a space for accommodating a cable 100 is provided in the sealing box body 10, and a filler inlet pipe 20 is connected to one of the half-box bodies 11, the filler inlet pipe 20 is used to inject filler, and the filler is used to fill the gap between the inside of the sealing box body 10 and the cable 100.

[0024] Among them, a connection end 101 is respectively provided at both ends of the sealed box body 10, and a joint 31 is detachably provided on the connection end 101. The cable 100 passes through the sealed box body 10 from one joint 31 and passes through the other joint 31 to the outside of the sealed box body 10. The sealed box body 10 is square in shape, and the connection end 101 is tubular. Here, one of the two connection ends 101 is an internal thread structure and the other is an external thread structure. The corresponding joint 31 is an external thread structure and an internal thread structure, so as to realize screw connection and fixation, and the cable 100 is supported and fixed by the joint 31.

[0025] Here, the half box bodies 11 are locked and connected via a locking member 111 , and the locking member 111 is a bolt.

[0026] The filler inlet pipe 20 is obliquely arranged on the outer end surface of the half box body 11, and a seal 21 is detachably arranged at one end of the filler inlet pipe 20. The seal 21 and the filler inlet pipe 20 are screwed and fixed by threaded cooperation.

[0027] Moreover, the inner diameter of the connecting end 101 at the side where the angle between the sealing box body 10 and the filling inlet tube 20 is smaller than the inner diameter of the sealing box body 10, so that the thickness of the filling in the connecting end 101 is smaller than the thickness at other positions. When the filling enters the filling inlet tube 20, it is transported forward along its inclined direction and gradually filled backward. Under the action of the connecting end 101 with a small inner diameter at the rear, the filling speed at the rear end is increased, so that seamless filling is achieved at both ends.

[0028] Here, the filler is an adhesive, specifically epoxy resin glue, which effectively fills and seals the interior, and the spacing between the wires of the cable 100 and between the wires and the sealing box body 10 is not less than 1 mm.

[0029] When the present invention is in use, at the desired installation position, the connector 31 is inserted into the cable 100, the two half box bodies 11 are disassembled and used to wrap the cable 100 inside, and the sealed box body 10 is formed by bolt locking, the connector 31 is connected to the sealed box body 10, and then the filler is filled from the filler inlet pipe 20 until the filling is completed, and the seal 21 is screwed into the filler inlet pipe 20 for sealing, and the installation is completed.

[0030] All the methods described herein can be performed in any suitable order. Any and all examples used, or exemplary language (such as "for example") provided herein are merely to better illustrate the present invention and are not intended to limit the scope of the present invention, unless the claims are included.
