Description

Technical Field

[0001] The utility model relates to the technical field of box-type transformer substations, in particular to a self-heat dissipation protection box-type transformer substation. Background Art

[0002] A box-type substation is a device that encapsulates substation equipment in a box, usually used in occasions where power supply is temporarily needed or space is limited. It usually includes transformers, circuit breakers, disconnectors, power meters and control equipment, etc. In some places where power supply is required outdoors, such as construction sites, field engineering projects, etc., the box-type substation needs to have a waterproof function to protect the equipment from adverse weather and environmental conditions.

[0003] The Chinese patent "A safety protection box-type substation" authorization announcement number "CN215497775U" intercepts water stains by setting a blocking plate, and sets a collecting box on the inner side of the protection box. The collecting box is set at the bottom of the ventilation hole of the protection box. The collecting box collects water stains splashed into the inside of the protection box, thereby maintaining a dry environment for the protection box.

[0004] In the above application, water stains entering the protective box are collected by a collecting box, but the collecting box is arranged inside the protective box. The rainwater entering the protective box may be dispersed and cannot effectively enter the collecting box, resulting in poor collection effect, thereby increasing the risk of damage to electrical equipment.

[0005] Therefore, a self-heat dissipation protection box-type substation is proposed to solve the above problems. Utility Model Content

[0006] The purpose of the present utility model is to provide a self-heating protective box-type substation in order to solve the above-mentioned problem, which improves the problem that the collecting box is arranged inside the protective box, and the rainwater entering the protective box may be dispersed and cannot effectively enter the collecting box, resulting in poor collection effect, thereby increasing the risk of damage to electrical equipment.

[0007] The utility model achieves the above-mentioned purpose through the following technical solutions: a self-heating protective box-type substation, comprising: a box-type substation body, one side of which is provided with a heat dissipation port; a protective mechanism, which is used to prevent rainwater from entering the interior of the box-type substation body, and the protective mechanism is arranged on one side of the box-type substation body; wherein the protective mechanism comprises a fixed frame fixedly connected to one side of the box-type substation body, the upper end of the other side of the fixed frame is fixedly connected with a fixed plate, the bottom end of the fixed plate is fixedly connected with a telescopic protective cover, the bottom end of the telescopic protective cover is fixedly connected with a movable plate, one side of the movable plate is slidably connected to the other side of the fixed frame, and a driving assembly is arranged on one side of the box-type substation body.

[0008] Preferably, the driving assembly includes a cylinder fixedly connected to one side of the box-type substation body, the front and rear ends of the box-type substation body are fixedly connected to guide frames, a connecting pipe is provided between the top of the cylinder and the bottom ends of the two guide frames, the inner wall of the cylinder is slidably connected to a piston plate, the bottom end of the piston plate is fixedly connected to a fixed rod, the surface of the fixed rod is slidably connected to a moving rod, the bottom end of the moving rod passes through the cylinder and is fixedly connected to one end of the moving plate, and the lower end of the surface of the cylinder is connected to a drain pipe. In rainy weather, under the action of the guide frame and the connecting pipe, rainwater is guided into the cylinder, which is conducive to pushing the piston plate to move downward, and under the action of the piston plate, the fixed rod and the moving rod, the moving plate is pushed to drive the bottom end of the telescopic protective cover to move downward, which is conducive to the telescopic protective cover to unfold and block the fixed frame.

[0009] Preferably, a spring is sleeved on the surface of the moving rod, the top end of the spring is fixedly connected to the bottom end of the piston plate, and the bottom end of the spring is fixedly connected to the inner bottom wall of the cylinder. Under the action of the spring, the device is reset when the precipitation stops.

[0010] Preferably, a mounting groove is provided at the upper end of the inner wall of the moving rod, a circular plate is slidably connected to the inner wall of the mounting groove, and the bottom end of the fixed rod penetrates into the interior of the mounting groove and is fixedly connected to the top end of the circular plate. During the process of the telescopic protective cover blocking the fixed frame, when the amount of rainwater entering the cylinder changes to a small extent, under the action of the spring, the circular plate and the mounting groove, it is conducive to the piston plate driving the fixed rod to move up and down within a small range, and the moving rod remains unchanged, thereby ensuring the stability of the telescopic protective cover when performing protection.

[0011] Preferably, a protective plate is fixedly connected to the top of the fixed frame, and the middle part of the protective plate is convex upward to form an inverted "V" shape, which is conducive to guiding rainwater falling on the fixed frame and improving the protective effect.

[0015] The beneficial effects of the utility model are:

[0016] 1. In rainy weather, under the action of the guide frame and the connecting pipe, rainwater is guided into the cylinder, which is conducive to pushing the piston plate downward, and under the action of the piston plate, the fixed rod and the moving rod, the moving plate drives the bottom end of the telescopic protective cover to move downward, which is conducive to the telescopic protective cover to expand and block the fixed frame, so that the fixed frame is in a closed state in rainy weather, thereby preventing rainwater from entering the interior of the box-type substation body through the fixed frame and the heat dissipation port, improving the protection effect of the electrical equipment inside the box-type substation body in rainy weather, thereby reducing the risk of damage to the electrical equipment;

[0017] 2. When the telescopic protective cover is blocking the fixed frame, when the amount of rainwater entering the cylinder changes slightly, the piston plate drives the fixed rod to move up and down in a small range under the action of the spring, the round plate and the mounting groove, and the moving rod remains unchanged, thereby ensuring the stability of the telescopic protective cover during protection.

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] When implementing: Figure 1-5 As shown, a self-heating protection box-type substation comprises: a box-type substation body 1, a heat dissipation port 2 is provided on one side of the box-type substation body 1; a protection mechanism 3, which is used to prevent rainwater from entering the inside of the box-type substation body 1 and is arranged on one side of the box-type substation body 1; wherein the protection mechanism 3 comprises a fixed frame 301 fixedly connected to one side of the box-type substation body 1, a fixed plate 302 is fixedly connected to the upper end of the other side of the fixed frame 301, a telescopic protective cover 303 is fixedly connected to the bottom end of the fixed plate 302, a movable plate 304 is fixedly connected to the bottom end of the telescopic protective cover 303, one side of the movable plate 304 is slidably connected to the other side of the fixed frame 301, and a driving assembly 305 is arranged on one side of the box-type substation body 1.

[0026] The fixing frame 301 is arranged on one side of the heat dissipation port 2, and a filter is fixed on the inner wall of the fixing frame 301. When the box-type substation body 1 is in use, the heat dissipation port 2 is used to dissipate the heat generated by the electrical equipment inside the box-type substation body 1, and the filter is used to intercept impurities entering the box-type substation body 1 through the heat dissipation port 2.

[0027] The telescopic protective cover 303 is a relatively mature device known in the art, and can be expanded or retracted as needed. In the initial state of the device, the telescopic protective cover 303 is in a retracted state.

[0028] like Figure 2 , Figure 4 and Figure 5 As shown, the driving assembly 305 includes a cylinder 3051 fixedly connected to one side of the box-type substation body 1, the front and rear ends of the box-type substation body 1 are fixedly connected with guide frames 3052, a connecting pipe 3053 is arranged between the top of the cylinder 3051 and the bottom ends of the two guide frames 3052, a piston plate 3054 is slidably connected to the inner wall of the cylinder 3051, a fixed rod 3055 is fixedly connected to the bottom end of the piston plate 3054, a moving rod 3056 is slidably connected to the surface of the fixed rod 3055, the bottom end of the moving rod 3056 passes through the cylinder 3051 and is fixedly connected to one end of the moving plate 304, and a drain pipe 3058 is connected to the lower end of the surface of the cylinder 3051. An angle is formed between the inner bottom wall of the guide frame 3052 and the horizontal plane.

[0029] When it rains, the guide frame 3052 is used to collect rainwater, and the rainwater falling to the top of the box-type substation body 1 will enter the guide frame 3052 under the action of the top slope of the box-type substation body 1. The connecting pipe 3053 is a three-way pipe, one end of which is connected to the cylinder 3051, and the other two ends are respectively connected to the two guide frames 3052. The rainwater entering the guide frame 3052 will enter the cylinder 3051 through the connecting pipe 3053 and push the piston plate 3054 to move downward, so that the fixed rod 3055 and the moving rod 3056 move downward at the same time, and push the moving plate 304 to pull The bottom end of the movable telescopic protective cover 303 moves downward, so that the telescopic protective cover 303 is expanded to block the fixed frame 301. When the piston plate 3054 moves to the bottom of the drain pipe 3058, the rainwater that continues to enter the cylinder 3051 will be discharged through the drain pipe 3058, so that the drain pipe 3058 is located below the drain pipe 3058. At the same time, the moving rod 3056 pushes the moving plate 304 to make the telescopic protective cover 303 complete the blocking of the fixed frame 301. At this time, the fixed frame 301 is in a closed state, and rainwater cannot enter the box-type substation body 1 through the fixed frame 301 and the heat dissipation port 2.

[0030] The two ends of the other side of the fixed frame 301 are fixedly connected to the limiting rods, and the inner wall of the movable plate 304 is slidably connected to the surface of the limiting rods.

[0031] like Figure 4 and Figure 5 As shown, a spring 3057 is sleeved on the surface of the moving rod 3056, the top end of the spring 3057 is fixedly connected to the bottom end of the piston plate 3054, and the bottom end of the spring 3057 is fixedly connected to the inner bottom wall of the cylinder 3051. A mounting groove 3059 is provided at the upper end of the inner wall of the moving rod 3056, and a circular plate 30510 is slidably connected to the inner wall of the mounting groove 3059. The bottom end of the fixed rod 3055 penetrates into the interior of the mounting groove 3059 and is fixedly connected to the top end of the circular plate 30510.

[0032] When rainwater squeezes the piston plate 3054 to move downward, the piston plate 3054 will first push the fixed rod 3055 downward, and drive the circular plate 30510 to move downward in the mounting groove 3059, and the spring 3057 will be compressed. When the bottom end of the piston plate 3054 contacts the top end of the moving rod 3056, the rainwater continues to squeeze the piston plate 3054. At this time, the piston plate 3054 will push the moving rod 3056 downward, and the spring 3057 will continue to be squeezed.

[0033] The piston plate 3054 is located below the drain pipe 3058. When the telescopic protective cover 303 blocks the fixed frame 301, when the amount of rainwater entering the cylinder 3051 changes slightly, under the action of the spring 3057, the circular plate 30510 and the mounting groove 3059, the piston plate 3054 will drive the fixed rod 3055 to move up and down within a smaller range, and the movable rod 3056 will remain stationary.

[0034] like Figure 3 As shown, the top of the fixed frame 301 is fixedly connected with a protective plate 307, and the middle part of the protective plate 307 is convex to form an inverted "V" shape. Rainwater falling on the top of the fixed frame 301 will be guided to the two ends of the fixed frame 301 under the action of the protective plate 307.

[0035] like Figure 1 As shown, the top of the box-type substation body 1 is provided with equally distributed guide grooves 101. The guide grooves 101 are inclined, and the lower end of the guide grooves 101 is located above the guide frame 3052. Rainwater falling on the top of the box-type substation body 1 will enter the guide frame 3052 through the guide grooves 101.

[0036] like Figure 4 and Figure 5 As shown, the inner wall of the piston plate 3054 is fixedly connected with a mounting tube 306, the bottom end of the mounting tube 306 penetrates the cylinder 3051, and the middle part of the mounting tube 306 is set as a bellows. When the piston plate 3054 moves downward, the mounting tube 306 will shrink. The diameter of the mounting tube 306 is small, and the top of the mounting tube 306 is connected with the piston plate 3054. When it rains, the rainwater entering the top of the piston plate 3054 is slowly discharged through the mounting tube 306, which does not affect the squeezing effect of the rainwater and the piston plate 3054. When the precipitation stops, the rainwater above the piston plate 3054 is discharged through the mounting tube 306, which can accelerate the evaporation of the rainwater above the piston plate 3054, so that the telescopic protective cover 303 releases the blockage of the fixed frame 301.

[0037] When the utility model is in use, in rainy weather, the guide frame 3052 is used to collect rainwater, and the rainwater entering the guide frame 3052 enters the cylinder 3051 through the connecting pipe 3053, and pushes the piston plate 3054 to move downward. At this time, the piston plate 3054 first pushes the fixed rod 3055 to drive the circular plate 30510 to move downward in the installation groove 3059, and the spring 3057 is compressed. When the bottom end of the piston plate 3054 contacts the top end of the moving rod 3056, the rainwater continues to squeeze the piston plate 3054. At this time, the piston plate 3054 will push the moving rod 3056 to move downward, and the spring 3057 will continue to be squeezed. When the moving rod 3056 moves downward, it will drive the moving plate 304 to move downward at the same time, and pull the bottom end of the telescopic protective cover 303 to move downward, so that the telescopic protective cover 303 is unfolded to The fixed frame 301 is blocked. When the piston plate 3054 moves to the bottom of the drain pipe 3058, rainwater that continues to enter the cylinder 3051 will be discharged through the drain pipe 3058. At the same time, the moving rod 3056 pushes the moving plate 304 to make the telescopic protective cover 303 complete the blocking of the fixed frame 301. At this time, the fixed frame 301 is in a closed state. When the amount of rainwater entering the cylinder 3051 changes to a small extent, under the action of the spring 3057, the circular plate 30510 and the mounting groove 3059, the piston plate 3054 will drive the fixed rod 3055 to move up and down in a small range, and the moving rod 3056 remains stationary, thereby keeping the telescopic protective cover 303 in a stable state. Therefore, in rainy weather, rainwater cannot enter the box-type substation body 1 through the fixed frame 301 and the heat dissipation port 2.

[0038] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
