Description

Technical Field

[0001] The utility model belongs to the technical field of transformer substation structures, and in particular relates to an assembled double-transformer box-type transformer substation. Background Art

[0002] The double-transformer box-type substation refers to a substation whose core structure consists of two transformers and its shape is a rectangular box.

[0003] On the other hand, the word "prefabricated" mentioned above refers to the outstanding structural feature of the substation, that is: movable installation, which makes the substation suitable for temporary construction, emergency use and other scenarios.

[0004] Generally, the existing common dual-transformer box-type substation mainly consists of: a shell, two transformers, a base, and a waterproof top cover, so as to achieve the basic dual-transformer safe use effect.

[0005] For example, a Chinese utility model patent with authorization announcement number CN219351096U and authorization announcement date 2023.07.14 discloses a new type of dual-transformer prefabricated substation, including a base, a U-shaped slide is slidably arranged on the base, a substation body is arranged at the upper end of the U-shaped slide, a protective cover block is slidably sleeved on the substation body, a first slide groove is opened on the front and rear sides of the base, a first slider is arranged on the inner side of the U-shaped slide, and the outer side of the first slider is slidably arranged on the inner wall of the first slide groove, a first bolt passes through the U-shaped slide, and the first bolt is threadedly connected to the base.

[0006] The substation in this utility model patent has the following general structural principles and advantages: the first slider on the U-shaped slide slides into the first slide groove of the base, and then the first bolt passes through the U-shaped slide and is threadedly connected to the base to fix the U-shaped slide on the base, and the second slider on the protective block slides into the second slide groove, and then the protective block is fixed to the substation body by the second bolt, so that the substation can be fully protected.

[0007] However, in actual use, the substation still has at least the following two shortcomings, which are also the technical problems to be solved by the utility model, namely:

[0008] First, the substation has only one main structure, which is used to install two transformers together. This results in relatively poor independence of the assembled structure. For example, when one transformer is disassembled, assembled, or repaired, it is relatively easy to bump into and affect the other one, which is not practical enough.

[0009] Second, the protective shielding block structure only has a snap-fitting and fixing effect on the substation body, and the fixing strength is relatively low, and the protective shielding block is relatively easy to be blown off by the wind.

[0010] So to sum up, there is an urgent need for a new type of assembled double-transformer box-type substation facility in which two transformers can be installed and used independently and the overall structural stability is relatively high. Utility Model Content

[0011] The utility model provides an assembled double-transformer box-type substation, which can arrange a box unit, a transformer, a slotted rainproof plate unit, a tension rod unit, and a transverse connecting rod unit on a slotted base unit, so that: 1. Two transformers are respectively installed in two box units, so that the installation and use of the two are more independent and convenient, and the flexible characteristics of the assembled structure are more prominent; 2. The overall structural stability of the substation is good, the connection strength is large, and it is not easy to disintegrate in bad weather.

[0012] The technical solution adopted by the utility model to solve the above-mentioned problem is: an assembled double-transformer box-type substation, the structure of which includes two transformers, and also includes two box units respectively used to install the two transformers, a slotted base unit snap-fitted on the two box units, a slotted rain shield unit snap-fitted on the two box units, a tension rod unit arranged on the slotted base unit and the slotted rain shield unit and used to be inserted into the foundation, and a transverse connecting rod unit arranged on the two box units.

[0013] A further preferred technical solution is that the box unit comprises a rectangular box with the slotted flashing plate unit and the slotted base unit respectively plugged into the upper and lower ends, and a hinged door arranged on the rectangular box.

[0014] A further preferred technical solution is that the slotted base unit includes a base plate, a base block arranged on the base plate, a base groove arranged on the base block and used to insert the two rectangular boxes, and a socket arranged on the base plate and used to pass the tension rod unit.

[0015] A further preferred technical solution is that the grooved flashing plate unit includes a top plate, a cover groove arranged on the lower surface of the top plate and used to insert the two rectangular boxes, and an opening block arranged on the side of the top plate and used to pass the tension rod unit.

[0016] A further preferred technical solution is that the tension rod unit includes an insertion rod arranged on the insertion hole and inserted into the foundation, a screw rod arranged on the upper end surface of the insertion rod and passing through the opening block, and a fastening nut arranged on the screw rod and used to press down the opening block.

[0017] A further preferred technical solution is that the transverse connecting rod unit includes two vertical hole blocks respectively arranged on the two rectangular boxes, a transverse screw rod arranged on the two vertical hole blocks, and two outer nuts arranged on the transverse screw rod and respectively used to engage the two vertical hole blocks.

[0018] A further preferred technical solution is that: the box unit also includes a wire hole arranged on the rectangular box; the transverse connecting rod unit also includes a vertical cover body arranged on the two rectangular boxes, which is open at the bottom and is used to cover the wire hole, the vertical hole block and the transverse screw, and an opening ring for installation arranged on the inner side of the vertical cover body and is used to engage the transverse screw.

[0019] A further preferred technical solution is that: the number of the insertion rods is 3, and one of the insertion rods is arranged on the outer side of the vertical cover body.

[0020] A further preferred technical solution is that the slotted flashing plate unit further includes an amplifying plate arranged on the top plate, and a diversion conical panel arranged on the amplifying plate.

[0021] A further preferred technical solution is that the tension rod unit further includes a conical block arranged on the lower end surface of the insertion rod. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0034] The following description is only a preferred embodiment of the present invention and is not intended to limit the scope of the present invention.

[0035] As attached Figure 1-7 As shown, an assembled double-transformer box-type substation structure includes two transformers 11, and also includes two box units 1 for installing the two transformers 11 respectively, a slotted base unit 2 snap-fitted on the two box units 1, a slotted rain shield unit 3 snap-fitted on the two box units 1, a tension rod unit 4 arranged on the slotted base unit 2 and the slotted rain shield unit 3 and used for inserting into the foundation a, and a transverse connecting rod unit 5 arranged on the two box units 1.

[0036] In this embodiment, the transformer 11 and the connecting line 12 are existing structures, and are matched with other necessary structures of the existing common substation to ensure that the basic substation effect can be achieved.

[0037] The main materials of the box unit 1, the slotted base unit 2, the slotted rainproof plate unit 3, the tension rod unit 4, and the transverse connecting rod unit 5 are all waterproof coated metal. The two box units 1 are used to install the two transformers 11 respectively, so that the two transformers 11 can operate independently as much as possible except for the necessary connection relationship, ensuring that the assembled and flexible advantages of the substation are more prominent.

[0038] In addition, another outstanding feature of the substation is its good structural stability and strong connection strength, which is reflected in:

[0039] First, the installation structure of the slotted flashing plate unit 3 includes not only engaging with the two box units 1, but also connecting with the tension rod unit 4, so that the slotted flashing plate unit 3 is not easily blown off by the wind;

[0040] Second, the two box units 1 are also provided with the transverse connecting rod unit 5, so that the two box units 1 have sufficient and appropriate pulling and fixing effects under the premise of independent operation, further preventing the substation from being severely impacted or even disintegrated and scattered in severe weather such as strong winds and heavy rains;

[0041] Thirdly, the tension rod unit 4 not only reinforces the connection between the slotted base unit 2 and the slotted flashing plate unit 3, but also inserts itself into the foundation a, so that the substation is not easily displaced as a whole.

[0042] The box unit 1 comprises a rectangular box 101 with the slotted flashing plate unit 3 and the slotted base unit 2 respectively inserted at the upper and lower ends, and a hinged door 102 arranged on the rectangular box 101 .

[0043] In this embodiment, the hinged door 102 is provided with various connecting parts required for its own opening and closing in accordance with the prior art, including hinges, handles, door locks, etc., to ensure that when the substation is operating normally, the hinged door 102 is stably closed, and when the transformer 11 needs to be operated and maintained, the hinged door 102 can be opened again.

[0044] The two hinged doors 102 are located on the same side, which is the front side of the substation, the side symmetrical to it is the back side of the substation, and the remaining two side sides are the sides of the substation.

[0045] The slotted base unit 2 includes a base plate 201, a base block 202 arranged on the base plate 201, a base groove 203 arranged on the base block 202 and used for inserting the two rectangular boxes 101, and a socket 204 arranged on the base plate 201 and used for passing the tension rod unit 4.

[0046] In this embodiment, the bottom plate 201 and the base block 202 are both circular, with the former having a larger diameter than the latter. The base groove 203 is rectangular in shape. When two rectangular boxes 101 are inserted into the base groove 203 at the same time, the widths of the four insertion gaps are all 0.5-1.0 cm, ensuring that the rectangular boxes 101 can be stably installed.

[0047] The insertion hole 204 is circular in shape, and its diameter is relatively small, and only allows the anti-tension rod unit 4 to pass through, so as to avoid a large shaking between the two.

[0048] In addition, a drainage hole may be further provided in the base groove 203, and a transverse screw hole for transversely clamping the rectangular box 101 may be further provided on the base block 202, and the screw hole needs to be used together with a bolt.

[0049] The slotted flashing plate unit 3 includes a top plate 301, a cover groove 302 arranged on the lower surface of the top plate 301 and used to insert the two rectangular boxes 101, and an opening block 303 arranged on the side of the top plate 301 and used to pass the tension rod unit 4.

[0050] In this embodiment, the top plate 301 is circular in shape, the length and width of the cover groove 302 are consistent with the base groove 203, and the number and position of the opening blocks 303 are also consistent and corresponding to the socket 204 and the anti-tension rod unit 4.

[0051] In addition, the depths of the cover groove 302 and the base groove 203 are relatively large, which only ensures that the hinged door 102 can be effectively opened and closed, and the ultimate goal is to stably install the two rectangular boxes 101.

[0052] The tension rod unit 4 includes an insertion rod 401 arranged on the insertion hole 204 and inserted into the foundation a, a screw rod 402 arranged on the upper end surface of the insertion rod 401 and passing through the opening block 303, and a fastening nut 403 arranged on the screw rod 402 and used to press down the opening block 303.

[0053] In this embodiment, the insert rod 401 and the screw rod 402 are integrally formed during production, and the combined structure is equivalent to a section of thread being provided downward from the upper end surface of the former.

[0054] So far, the connection method of the tension rod unit 4 from bottom to top is: inserting into the foundation a, plugging into the socket 204, plugging into the hole block 303, and pressing down to engage the hole block 303. Finally, it can: 1. reinforce the slotted rainproof plate unit 3 to prevent it from being blown off by strong wind; 2. fix the entire substation to prevent it from being carried away and displaced by strong wind and water flow; 3. reinforce the two box units 1.

[0055] The transverse connecting rod unit 5 includes two vertical hole blocks 501 respectively arranged on the two rectangular boxes 101, a transverse screw rod 502 arranged on the two vertical hole blocks 501, and two outer nuts 503 arranged on the transverse screw rod 502 and respectively used to engage the two vertical hole blocks 501.

[0056] In this embodiment, the vertical hole block 501 is located on the back side of the rectangular box 101 , so that the reinforced connection effect of the transverse connecting rod unit 5 does not affect the normal opening and closing effect of the hinged door 102 .

[0057] The structure of the vertical hole block 501 is similar to that of the opening block 303. Both are a combination structure of a block and a circular hole. The main body surface of the former is vertically arranged, while the main body surface of the latter is vertically arranged.

[0058] Finally, the two outer nuts 503 respectively and adequately and directly tighten the two vertical hole blocks 501 , with the ultimate goal of reinforcing the connection at the substantially center position of the two rectangular boxes 101 .

[0059] At this point, for the two rectangular boxes 101, their upper parts are socketed by the cover groove 302, their middle parts are tied by the transverse screw 502, and their lower parts are socketed by the base groove 203, finally obtaining a sufficient and comprehensive reinforcement effect.

[0060] The box unit 1 also includes a wire hole 103 arranged on the rectangular box 101; the horizontal connecting rod unit 5 also includes a vertical cover body 504 arranged on the two rectangular boxes 101 and opened at the bottom, and used to cover the wire hole 103 and the vertical hole block 501 and the horizontal screw 502, and an installation open ring 505 arranged on the inner side surface of the vertical cover body 504 and used to engage the horizontal screw 502.

[0061] In this embodiment, the wire hole 103 serves to allow the connecting wire 12 to pass through, thereby indirectly allowing the transformer 11 to be effectively used.

[0062] Therefore, correspondingly, the rectangular box 101 at this time has a certain risk of water ingress at the wire hole 103, so the vertical cover 504 is provided so that the above-mentioned wire passing effect and water leakage prevention effect can be properly achieved.

[0063] The structure of the vertical cover 504 is a rectangular box without a bottom plate and a side plate. The position of the vertical cover 504 without the side plate is used to buckle on the rectangular box 101, and is also the position where the connecting line 12 is inserted. The position of the vertical cover 504 without the bottom plate is the position where the connecting line 12 is extended.

[0064] Finally, the vertical cover 504 is then engaged with the screw 502 through the installation opening ring 505 to ensure its own installation stability. For the specific structure, please refer to the attached Figure 6 and 7 .

[0065] The number of the insertion rods 401 is three, and one of the insertion rods 401 is disposed on the outer side of the vertical cover body 504 .

[0066] In this embodiment, one of the plug rods 401 is respectively provided on both sides and the back of the hinged door 102 to ensure that the substation has a sufficient and appropriate reinforcement effect, and the reinforcement effect also cannot affect the normal opening and closing of the hinged door 102.

[0067] The insertion rod 401 located at the back is used to laterally support the vertical cover 504 also located at the back, so that the latter has higher installation stability.

[0068] The slotted flashing plate unit 3 further includes an amplifying plate 304 disposed on the top plate 301 , and a diversion cone panel 305 disposed on the amplifying plate 304 .

[0069] In this embodiment, the amplifying plate 304 is circular in shape, and its diameter is less than or equal to the diameter of the circular bottom edge of the guide cone plate 305 , and greater than the diameter of the top plate 301 .

[0070] The main function of the amplifying plate 304 is to prevent water from entering the rectangular box 101. In addition, the circular bottom edge of the diversion cone panel 305 is welded to the amplifying plate 304 to prevent a large amount of water from leaking inwards at the joint.

[0071] The anti-tension rod unit 4 further includes a conical block 404 arranged on the lower end surface of the insertion rod 401 .

[0072] In this embodiment, the insertion rod 401, the screw rod 402 and the conical block 404 are integrally formed, and the central axes of the three coincide. The conical block 404 mainly functions to reduce the resistance difficulty of the insertion rod 401 into the foundation a.

[0073] In addition, when the substation is moved, the fastening nut 403 needs to be unscrewed first, the slotted rain shield unit 3 is removed, and finally the insertion rod 401 is pulled out. Otherwise, if the insertion rod 401 is directly pulled upward, it is easy to damage the amplification plate 304 and the guide cone plate 305.

[0074] The above is a detailed description of the implementation of the utility model in conjunction with the accompanying drawings, but the utility model is not limited to the above implementation. Various modifications can be made within the knowledge of ordinary technicians in the technical field without departing from the purpose of the utility model. These are all non-creative modifications and are protected by patent law as long as they are within the scope of the claims of the utility model.
