Description

Technical Field

[0001] The present invention relates to a prefabricated cabin for outdoor use, belonging to the technical field of prefabricated cabins. Background Art

[0002] At present, the prefabricated cabin in power equipment is composed of a cabin body, primary and secondary combined equipment inside the cabin, cabin auxiliary facilities, and related power distribution cabinets, equipment screens, etc. They are assembled in the factory and transported to the construction site for hoisting.

[0003] With the maturity of prefabricated cabin technology, power equipment is gradually developing towards prefabricated and modular directions, and many substations and energy storage power stations have adopted prefabricated cabin assembly methods.

[0004] In recent years, the new energy industry has developed rapidly, and a large number of energy storage power stations supporting wind power and photovoltaic have been built. The energy storage system of the energy storage power station is mainly divided into two parts: an energy storage booster cabin and a battery cabin, both of which are placed outdoors in a prefabricated cabin assembly method.

[0005] Existing prefabricated cabins, as shown in Figure 1 and Figure 2 in the attached drawings of the specification, have an energy storage converter (PCS3) with a certain weight installed on the top of the cabin body of the prefabricated cabin, causing the top of the cabin body to be concave under stress, and there is water accumulation on the uneven top on rainy days. The three-phase alternating current of the energy storage converter is connected to the AC molded case circuit breaker inside the cabin through the incoming line cable 20, and the two-phase direct current of the energy storage converter is connected to the DC molded case circuit breaker inside the cabin through the outgoing line cable 21. The incoming and outgoing line cables are connected to the top wall of the cabin body through the PG waterproof head 2, that is, the incoming and outgoing line cables are hermetically connected to the cabin body through the cable sealing joint. The cable sealing joint uses a gland head. During the use process, the following problems exist: ① Due to the viscosity of water and the inability to make the top of the cabin body 1 absolutely flat, water accumulation occurs on the top of the cabin body 1, which may further cause the PG waterproof head 2 (the PG waterproof head is also a PG joint, and the Chinese name of the PG joint is a gland head) installed on the top of the cabin body 1 to be soaked in water for a long time, and a small number of PG waterproof heads 2 have water seepage; ② The heat dissipation holes 11 at the position of the louver 110 behind the cabin body 1 (on the side opposite to the cabin door) play a role in heat dissipation, but in extreme weather, water still splashes in; ③ When the rainfall is too large and there is too much rain, the flanging 100 of the cabin door 10 cannot drain the rainwater from both ends of the flanging 100 in time, resulting in water overflowing the flanging 100 and flowing into the interior of the cabin body 1; these situations seriously affect the safe operation of the electrical components inside the cabin body 1. In addition, there is only one cabin door in a single compartment inside the existing cabin body, and ④ the design of the single-sided cabin door 10 of the cabin body is also not convenient for the installation of electrical components inside the cabin. Summary of the Invention

[0006] The object of the present invention is to provide a prefabricated cabin for outdoor use, so as to solve the problem of water seepage at the position where the gland is installed on the top of the existing prefabricated cabin body.

[0007] To achieve the above object, the solution of the present invention includes:

[0008] A prefabricated cabin for outdoor use of the present invention includes a cabin body. The top wall of the cabin body is used for installing a cable sealing joint, and the upper surface of the top wall has a slope facing the outside and bottom of the cabin body, and the slope is used for installing the cable sealing joint.

[0009] Further, the slope angle of the slope is between 10 degrees and 50 degrees.

[0010] Further, a cabin door is provided on the side wall of the cabin body, and the top wall above the cabin door extends beyond the cabin door in the horizontal direction.

[0011] Further, the bottom surface of the top wall extending beyond the cabin door has an inclined surface facing the outside and bottom of the cabin body, so that the top wall covers the upper edge of the cabin door in the vertical direction.

[0012] Further, heat dissipation holes for heat dissipation inside the cabin body are provided on the downward bottom surface of the top wall extending beyond the cabin door.

[0013] Further, the compartments of the cabin body have at least two external cabin doors.

[0014] Further, the number of cabin doors in the compartment of the cabin body is two, and the two cabin doors are arranged on the opposite side walls of the cabin.

[0015] The cable sealing joint of the existing prefabricated cabin for outdoor use is arranged on the relatively flat top of the prefabricated cabin. Different from the existing prefabricated cabin, the cable sealing joint of the prefabricated cabin for outdoor use of the present invention is arranged on a slope inclined downward and outward, so that rainwater can quickly and effectively drip or flow down along the slope, effectively reducing the possibility of water seepage or even water ingress into the cabin body of the prefabricated cabin.

[0022] To make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0023] An embodiment of a prefabricated cabin for outdoor use:

[0024] Existing prefabricated cabins, as shown in Figure 1 and Figure 2 in the accompanying drawings of the specification, have the following problems during use: ① Due to the viscosity of water and the inability to make the top of the cabin body 1 absolutely flat, water accumulation occurs on the top of the cabin body 1, which may further cause the PG waterproof head 2 (the PG waterproof head is also a PG connector, and the Chinese name of the PG connector is gland) installed on the top of the cabin body 1 to be soaked in water for a long time, and a small number of PG waterproof heads 2 have water seepage; ② The heat dissipation holes 11 at the position of the louver 110 on the back of the cabin body 1 (the side opposite to the cabin door) play a role in heat dissipation, but in extreme weather, water still splashes in; ③ When there is too much rain, the flange 100 of the cabin door 10 cannot drain the rainwater in time, resulting in water overflowing the flange and flowing into the cabin body 1; these situations seriously affect the safe operation of the electrical components in the cabin body 1. In addition, there is only one cabin door in a single compartment of the existing cabin body, and ④ the design of the single-sided cabin door 10 is also inconvenient for the installation of electrical components in the cabin.

[0025] During the actual use of the existing cabin body, water seepage, water ingress and other situations have occurred. In order to completely solve the problem of water ingress into the cabin body, the original cabin body has been improved, which can effectively improve the overall protection performance of the cabin body.

[0026] For problem ①, the place where the PG waterproof head is installed is made into a slope to prevent water accumulation; for problem ③, the size of the cabin top is increased to prevent rainwater from directly pouring into the cabin door; for problem ②, the original bottom louver heat dissipation openings are changed to a protruding position above the top cabin door, which can effectively prevent rain; for problem ④, at least two cabin doors are provided in a single compartment of the cabin body, specifically, cabin doors are left at the front and back of the cabin body, which is convenient for the installation and maintenance of electrical components in the cabin.

[0027] By improving the cabin body structure, the problem of rain protection of the cabin body is effectively solved, and the protection level of the cabin body can reach IP54 required by users. The ingenious slope treatment of the PG waterproof head, the design of the front and rear cabin doors, and the increase in the size of the cabin top not only play the role of a rain shelter, but also well reserve heat dissipation holes.

[0028] A prefabricated cabin for outdoor use, such asFigure 3 and Figure 4 As shown, it includes a cabin body 1, and the cabin top wall 12 of the cabin body 1 is used to install the cable sealing joint. The upper surface of the cabin top wall 12 has a slope inclined toward the outside and bottom of the cabin body 1, and the slope is used to install the cable sealing joint. By providing a downward and outward inclined slope for installing the cable sealing joint, rainwater can drip or flow away quickly and effectively along the slope, effectively reducing the possibility of water seepage or even water ingress into the prefabricated cabin body 1.

[0029] Among them, the cable sealing joint can adopt a cable gland (PG waterproof gland 2).

[0030] The cable gland is used to pass the incoming cable 20 or the outgoing cable 21, and the incoming cable 20 and the outgoing cable 21 are electrically connected to the electrical equipment. The incoming cable 20 and the outgoing cable 21 are electrically connected to the PCS 3 arranged outside the prefabricated cabin.

[0031] Specifically, if the slope is too small, water may be trapped, which may cause water seepage at the location of the cable gland (cable sealing joint); if the slope is too large, the cable at the cable gland will be bent and damaged, and there is a possibility of water trapping at the bend. In order to avoid the slope being too large or too small, the slope of the present invention has a value range of 10 degrees to 50 degrees, that is, the slope can be selected in the range of 10° to 50°, which effectively avoids the occurrence of water trapping on the slope or water trapping on the cable at the cable gland, and improves the waterproof effect of the cabin 1.

[0032] Specifically, a hatch door 10 is installed on the side wall of the cabin body 1, and a cabin top wall 12 above the hatch door 10 is arranged beyond the hatch door 10 so that the cabin top wall 12 completely covers the upper part of the hatch door 10 in the horizontal direction. The present invention protects the hatch door 10 from rain by using the cabin top wall 12 arranged beyond the hatch door 10, so as to avoid the situation in which the flange 100 on the upper part of the hatch door 10 cannot drain the rainwater in time when there is too much rain, causing water to overflow the flange 100 of the hatch door 10 and flow into the interior of the cabin body 1.

[0033] Specifically, the bottom surface of the cabin top wall extending beyond the cabin door has an inclined surface inclined toward the outside and bottom of the cabin body, so that the cabin top wall covers the upper edge of the cabin door in the vertical direction. The present invention protects the cabin door from rain by means of the cabin top wall arranged beyond the cabin door, thereby preventing the flange at the upper edge of the cabin door from being unable to drain rainwater in time when there is too much rain, causing water to overflow the flange of the cabin door and flow into the interior of the cabin body.

[0034] Although the heat dissipation holes 11 at the position of the louver 110 behind the existing cabin body 11 (on the side opposite to the cabin door 10) play a role in heat dissipation, water still splashes in during extreme weather. To solve this problem, the bottom surface of the cabin top wall 12 extending beyond the cabin door 10 is provided with heat dissipation holes 11 for heat dissipation inside the cabin body 1, that is, the outlet of the heat dissipation channel inside the cabin body 1 is arranged on the bottom surface of the cabin top wall 12 extending beyond the cabin door 10. The cabin top wall 12 provided beyond the cabin door 10 in the present invention provides a position for opening the heat dissipation holes 11, effectively blocking rain for the heat dissipation holes 11 and preventing rain from splashing into the cabin body 1 through the heat dissipation holes 11.

[0035] The cabin door of the existing prefabricated cabin is one cabin door for one compartment, and one cabin door basically occupies one side wall. Since there is only one cabin door 10 in a single compartment inside the existing cabin body 1 and the design of the single-sided cabin door 10 is not convenient for the installation of electrical components inside the cabin. To solve this problem, at least two external cabin doors 10 are provided in the compartments of the cabin body 1 of the present invention, which is convenient for the installation of components inside the cabin.

[0036] Specifically, two external cabin doors 10 are provided in each compartment of the cabin body, which is convenient for the installation of components inside the cabin.

[0037] Specifically, the two cabin doors 10 are arranged on opposite cabin side walls, which is convenient for the installation of components inside the cabin.

[0038] As another embodiment, cabin doors are opened on the compartment side walls of the side walls of each cabin body compartment that serve as the cabin body side walls of the entire prefabricated cabin. Among them, the left compartment at the end of the entire prefabricated cabin can be provided with cabin doors on the front wall, rear wall and left side wall; the right compartment at the end of the entire prefabricated cabin can be provided with cabin doors on the front wall, rear wall and right side wall; the compartments in the middle or at the end of the entire prefabricated cabin are provided with cabin doors on the front wall and rear wall, which are all convenient for the installation of cabin door components.
