Description

Technical Field

[0001] This utility model relates to the field of prefabricated substation technology, specifically a ventilation and dustproof structure for prefabricated substations. Background Technology

[0002] A prefabricated substation, also known as a prefabricated transformer substation, is a factory-prefabricated, compact indoor or outdoor power distribution device that integrates high-voltage switchgear, distribution transformers, and low-voltage power distribution equipment according to a specific wiring scheme. It organically combines the functions of transformer voltage reduction and low-voltage power distribution, and installs them in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, theft-proof, heat-insulated, fully enclosed, and movable steel structure box. It is particularly suitable for urban power grid construction and renovation, and is a brand-new type of substation that has emerged after civil engineering substations.

[0003] A search revealed that Chinese Utility Model Application No. 202022684722.7 proposes a European-style dustproof ventilation structure for substations. The utility model describes a structure as follows: "This utility model includes a slot, a handle, a first rotating rod, a brush, and a handle. When the filter screen is full of dust, rotating the handle causes the second rotating rod to rotate, which in turn causes the first rotating rod to rotate. The rotation of the first rotating rod causes the movable sleeve to move back and forth, allowing the brush and filter screen to rub against each other, thus cleaning the dust on the filter screen quickly and conveniently. When the filter screen is particularly dusty or needs to be replaced, rotating the screw separates the filter screen from the rectangular cylinder. Holding the handle allows the filter screen to be removed from the rectangular cylinder, facilitating deep cleaning or replacement, ensuring the filter screen always maintains ideal ventilation."

[0004] In this European-style substation dustproof ventilation structure, when cleaning the dust on the filter screen surface, the first slide rail needs to be moved into the ventilation slot to prevent dust from entering the interior of the box-type substation. However, this reduces the ventilation effect of the box-type substation and affects its performance. Therefore, a new ventilation and dustproof structure for box-type substations is proposed to solve the above problems. Utility Model Content

A first movable rod is fixedly mounted at the bottom of the first threaded sleeve, passing through and extending into the compartment. A shielding plate that fits against the back of the partition plate is fixedly mounted at the bottom of the first movable rod.

[0008] Furthermore, a first movable hole is provided on the top of the chamber, and the first movable hole matches the first movable rod.

[0009] Furthermore, the cleaning mechanism includes a second housing, which is fixedly connected to the outer wall of the chamber.

The top of the second threaded rod passes through the second housing and is fixedly mounted with a second knob. A second threaded sleeve is installed on the external thread of the second threaded rod. A second movable rod is fixedly mounted on the outside of the second threaded sleeve, passing through and extending into the interior of the chamber. A cleaning brush that fits against the front of the filter screen is fixedly mounted on the outside of the second movable rod.

[0010] Furthermore, a second movable hole is provided on the top of the chamber, and the second movable hole matches the second movable rod.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0021] Please see Figure 1-3 The ventilation and dust prevention structure of the box-type substation in this embodiment includes a box-type substation body 1. The front of the box-type substation body 1 is provided with ventilation holes. A compartment 2 is fixedly installed on the front of the box-type substation body 1.

A partition plate 4 is fixedly installed inside the compartment 2. A filter screen 5 is fixedly installed between the inside of the compartment 2 and the partition plate 4.

[0022] Specifically, when cleaning the first filter 5, the user first uses the shielding mechanism 3 to shield the back of the first filter 5, and then uses the cleaning mechanism 6 to clean the front of the first filter 5, so that the second filter 5 can filter the air entering the compartment 2, thereby enhancing the ventilation effect of the main body 1 of the box-type substation and improving the usage effect.

[0023] In this embodiment, the shielding mechanism 3 includes a first housing 31, which is fixedly connected to the top of the compartment 2. A first threaded rod 32 is rotatably mounted on the inner side wall of the first housing 31 via a first bearing. The side of the first threaded rod 32 away from the inner side wall of the first housing 31 passes through the first housing 31 and is fixedly mounted with a first knob 33. A first threaded sleeve 34 is installed on the external thread of the first threaded rod 32. A first movable rod 35 is fixedly mounted on the bottom of the first threaded sleeve 34, which passes through and extends into the compartment 2. A first movable hole is opened on the top of the compartment 2, which matches the first movable rod 35. A shielding plate 36 that is in contact with the back of the partition plate 4 is fixedly mounted on the bottom of the first movable rod 35.

[0024] Specifically, by rotating the first knob 33, the first knob 33 drives the first threaded rod 32 to rotate, and the first threaded rod 32 drives the first threaded sleeve 34, the first moving rod 35 and the baffle plate 36 to move, so that the baffle plate 36 fits against the inner wall of the compartment 2 and the back of the partition plate 4.

[0025] In this embodiment, the cleaning mechanism 6 includes a second housing 61, which is fixedly connected to the outer wall of the chamber 2. A second threaded rod 62 is rotatably mounted on the inner bottom wall of the second housing 61 via a second bearing. The top of the second threaded rod 62 passes through the second housing 61 and is fixedly mounted with a second knob 63. A second threaded sleeve 64 is installed on the outer thread of the second threaded rod 62. A second moving rod 65 is fixedly mounted on the outer side of the second threaded sleeve 64, passing through and extending into the chamber 2. A second moving hole is opened on the top of the chamber 2, which matches the second moving rod 65. A cleaning brush 66 that fits against the front of the filter screen 5 is fixedly mounted on the outer side of the second moving rod 65. A slider extending into the partition plate 4 is fixedly mounted on the outer side of the cleaning brush 66. A groove matching the slider is opened inside the partition plate 4.

[0026] Specifically, by rotating the second knob 63, the second knob 63 drives the second threaded rod 62 to rotate, and the second threaded rod 62 drives the second threaded sleeve 64, the second moving rod 65 and the cleaning brush 66 to move, so that the cleaning brush 66 cleans the dust on the front of the filter screen 5.

[0027] In this embodiment, a through hole is provided at the bottom of the hopper 2, and a horizontal plate 7 extending into the hopper 2 is inserted into the front of the hopper 2. A handle is fixedly installed on the front of the horizontal plate 7. A collection mechanism 8 is provided at the bottom of the hopper 2. The collection mechanism 8 includes an L-shaped plate 81, which is fixedly connected to the bottom of the hopper 2. A collection box 82 is placed on the top of the L-shaped plate 81.

[0028] Specifically, by holding the handle, the horizontal plate 7 is removed from inside the compartment 2, and the dust falls downwards into the collection box 82.

[0029] The working principle of the above embodiment is:

[0030] When cleaning the first filter screen 5, the user first rotates the first knob 33, which drives the first threaded rod 32 to rotate. The first threaded rod 32 drives the first threaded sleeve 34, the first moving rod 35, and the baffle plate 36 to move, so that the baffle plate 36 fits against the inner wall of the compartment 2 and the back of the partition plate 4. Then, the user rotates the second knob 63, which drives the second threaded rod 62 to rotate. The second threaded rod 62 drives the second threaded sleeve 64, the second moving rod 65, and the cleaning brush 66 to move, so that the cleaning brush 66 cleans the front of the filter screen 5. The user then holds the handle and removes the horizontal plate 7 from inside the compartment 2. The dust falls downward into the collection box 82, allowing the second filter screen 5 to filter the air entering the compartment 2, thus enhancing the ventilation effect of the main body 1 of the box-type substation and improving the usage effect.
