[0041] In order to make the purpose, technical solution and advantages of the embodiment of the utility model clearer, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiment of the utility model. Obviously, the described embodiment is a part of the embodiment of the utility model, not all of the embodiments. Based on the embodiment of 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.

[0042] First embodiment

[0043] Sewage treatment plants often have a large amount of sewage, so the environment where the control box is located is very humid and needs to be moisture-proof. To this end, this embodiment discloses a control box for a sewage treatment station, including a box body 1 and a bracket 2 arranged in the box body 1, wherein the box body 1 includes: a bottom ventilation hole 3 opened at the bottom of the box body 1; a leg 4 arranged at the bottom of the box body 1, the leg 4 lifting the bottom of the box body 1, and forming a spacing space between the bottom of the box body 1 and the supporting plane of the leg 4; the bracket 2 includes: a longitudinal bracket 201 fixedly arranged on the inner wall of the box body 1; a ventilation storage box 202 arranged below the longitudinal bracket 201, the ventilation storage box 202 is arranged adjacent to the bottom ventilation hole 3, and the storage box ventilation hole is connected to the bottom ventilation hole 3.

[0044] In an example, you can refer to Figure 1The box body 1 is a metal box. In some examples, the metal surface can be painted to prevent rust. The bottom ventilation holes 3 of the box body 1 can effectively promote the air circulation inside the box body 1 and reduce the residence time of humid air inside the box body 1. At the same time, in order to prevent humid air from directly invading the interior of the box body 1, legs 4 are also specially provided. These legs 4 are arranged at the bottom of the box body 1, and can lift the bottom of the box body 1 to a certain height, thereby forming a spacing space between the bottom of the box body 1 and the supporting plane of the legs 4. This spacing space can be used as a spacing area. Even if humid air contacts the bottom of the box body 1, it will not directly invade the interior of the box body 1, thereby playing a good moisture-proof role.

[0045] Combination Figure 2 Continuing to understand this example, the longitudinal bracket 201 is a rectangular steel pipe arranged at each corner of the inner wall of the box body 1, and a plurality of transverse placement racks 203 are connected between the longitudinal brackets 201. The ventilated storage box 202 is a rectangular box body 1, and each corner of the box body 1 is fixedly arranged with the longitudinal bracket 201. In some cases, the fixing method can be a reliable method such as welding, bolt connection, etc., to ensure that the ventilated storage box 202 is firmly fixed inside the box body 1.

[0046] refer to Figure 1-2 It is not difficult to understand that the ventilation storage box 202 is located at the bottom, and the bottom ventilation hole 3 can effectively ventilate it. The ventilation storage box 202 is used to set hardware equipment that is not often replaced, and it is sealed in the ventilation storage box 202 to keep ventilation.

[0047] Second embodiment

[0048] Based on the above embodiments, the structure in this example can refer to Figure 3 to understand. Similar to the previous embodiment, the ventilated storage box 202 is fixed on the longitudinal bracket 201, and the wall of the ventilated storage box 202 facing the bottom ventilation hole 3 is provided with a storage box ventilation hole. In this example, the ventilated storage box 202 is a grid plate structure. This structure increases the ventilation area of ​​the ventilated storage box 202. At the same time, the grid structure also has a certain dustproof effect, which can prevent dust and other impurities from entering the interior of the ventilated storage box 202 while ensuring ventilation, thereby protecting the operating environment of the internal equipment.

[0049] like Figure 3In the exemplary structure shown, a ventilation chamber 5 is also left at the bottom of the box body 1, and the bottom ventilation holes 3 and the multiple ventilated storage boxes 202 arranged at different heights surround the ventilation chamber 5 to form the ventilation chamber 5. In this example, the storage box ventilation holes are connected to the bottom ventilation holes 3 via the ventilation chamber 5. The structure in this example not only increases the ventilation space at the bottom, but also provides an adjacent ventilation environment for the multiple ventilated storage boxes 202. Specifically, the bottom ventilation holes 3 are connected to the ventilation chamber 5, and the ventilation chamber 5 is connected to the storage box ventilation holes on each ventilated storage box 202. Figure 4 In the structure shown, the area of ​​the box body 1 corresponding to the ventilation storage box 202 is a glass plate 6 to facilitate regular observation of the internal conditions.

[0050] Third embodiment

[0051] Based on the above embodiments, continue to refer to Figure 3 It is understood that the bottom ventilation hole 3 in this example includes: a side hole 301 arranged on the bottom side wall of the box body 1; and a bottom hole 302 arranged on the bottom wall of the box body 1. The ventilated storage box 202 includes: a side storage box 2021 with at least one wall facing the side hole 301; and an upper storage box 2022 with at least one wall facing the bottom hole 302. The ventilated storage box 202 described in this example is arranged in a high and low staggered manner so that it forms the ventilation chamber 5. In different examples, a larger number of ventilated storage boxes 202 can be arranged adjacent to the ventilation chamber 5 in a box body 1, and the structure of this embodiment does not limit other implementations of the present utility model. Figure 4 In the example shown, the upper storage box 2022 , the side storage box 2021 , the side hole 301 , and the bottom hole 302 surround and form the ventilation chamber 5 .

[0052] Fourth embodiment

[0053] Based on the above-mentioned embodiment, the ventilation chamber 5 can also be used to set a blowing device. In this example, a blower is also provided in the partition space, and the air outlet of the blower is located in the ventilation chamber 5. In the structure of this example, it is possible to flexibly place a device for regular dehumidification under the box body 1. For example, a device for blowing hot air is provided. The air outlet of the blower is located in the ventilation chamber 5, ensuring that fresh air can be blown directly to the ventilation storage box 202 and other equipment, effectively removing humid air and keeping the equipment dry.

[0054] Based on the above embodiments, in some examples, the top of the box body 1 is further provided with a top ventilation hole 101. Figure 5For understanding, this embodiment also adds a top vent 101 on the top of the box body 1. This improvement forms a convection channel with the bottom vent 3 below, further improving the dehumidification effect of the control box. When the blower is working, fresh air enters from the bottom vent 3, passes through the ventilation chamber 5 and the ventilation storage box 202, and then is discharged from the top vent 101, forming a complete convection cycle. This convection cycle not only helps to quickly remove the humid air inside the control box, but also effectively reduces the temperature of the equipment during operation, and improves the stability and service life of the equipment.

[0055] Based on the above embodiments, in some examples, the upper area of ​​the longitudinal bracket 201 is further provided with a transverse placement rack 203. The placement rack can be used to set up a power distribution circuit, such as Figure 6 An exemplary power distribution diagram is shown, which can be set in the box 1. In the power distribution diagram shown in the figure, -FU1 and -FU2 are both RT18-32 with 4A fuse core. 1DY is a distribution box, and the other marks are conventional marks in the field, which will not be repeated.

[0056] In this embodiment, a horizontal placement rack 203 is further provided in the upper area of ​​the longitudinal bracket 201. This facilitates the installation of equipment such as power distribution circuits. Equipment such as power distribution circuits usually have a short service life and may need frequent maintenance or adjustment. Placing them on the horizontal placement rack not only facilitates daily maintenance and management, but also avoids interference with other equipment.

[0057] The ventilation storage box 202 is used to set up equipment that is relatively expensive and is not often replaced, such as analytical instruments, PLC equipment, CPU, etc. The ventilation storage box 202 can protect the equipment from moisture, such as dust, etc.

[0058] Fifth embodiment

[0059] Based on the above embodiments, in some specific embodiments, due to site restrictions or other factors, some control boxes have to be set up outdoors. In this case, the prior art usually protects the control box from rain by setting up an independent canopy. Although this method has played a role in sheltering from rain to a certain extent, it blocks the sunlight on sunny days. The interior of the control box that lacks sunlight for a long time is prone to moisture, which in turn affects the normal operation and service life of the internal equipment.

[0060] To this end, the control box in this example also includes an opening and closing cover 7 fixed to the upper part of the box body 1. The specific structure can be referred to Figure 7-8It is understood that the opening and closing cover 7 includes: a reference member 701 fixed on the side wall of the box body 1, a pulley 702 extending from the top of the reference member 701, and in some specific examples, a rolling pulley 702 is provided at the upper edge of the box body 1. These pulleys 702 can be fixed pulleys 702 or movable pulleys 702. In the illustrated example, a pulley 702 is also provided at the upper edge of the box body 1 to facilitate the smooth movement of the opening and closing member 703. The specific structure of the pulley 702 and its connection structure with the box body 1 can be designed and selected according to actual conditions, as long as the smooth movement and fixation of the opening and closing member 703 can be achieved. In addition, the pulley 702 can also be equivalently replaced, for example, using a slide rail, a slider or the like.

[0061] And, the overall plate-shaped opening and closing member 703, any side wall of the opening and closing member 703 is provided with a long strip groove body 704, wherein the pulley 702 is inserted into the long strip groove body 704. In different examples, when the opening and closing member 703 needs to be opened, the pulley 702 slides in the long strip groove body 704 to guide the opening and closing member 703 to move upward smoothly. Once it moves to a sufficient height, the opening and closing member 703 will rotate around the pulley 702. This rotation design allows the opening and closing member 703 to smoothly cover the top of the box body 1. When the opening and closing member 703 needs to be closed, the process is the opposite, and the opening and closing member 703 rotates in the opposite direction around the pulley 702 and moves downward until it returns to the initial position.

[0062] exist Figure 7 In the example shown, the opening and closing cover 7 includes: a left reference member 7011 disposed on the left side of the box body 1, a right reference member 7012 disposed on the right side of the box body 1; and a left opening and closing member 7031 disposed on the left side of the box body 1, and a right opening and closing member 7032 disposed on the right side of the box body 1. The left opening and closing member 7031 and the right opening and closing member 7032 rotate around their respective pulleys 702, and cooperate to cover the entire box body 1.

[0063] Although the structure in this example is to realize the covering by the left opening and closing member 7031 and the right opening and closing member 7032 on both sides, this does not mean that this is the only implementation method. In fact, in different embodiments, the covering function can be realized when the opening and closing member 703 is only set on one side.

[0064] Specifically, the left opening and closing member 7031 extends a protrusion 7033 toward the outer wall surface; the right opening and closing member 7032 extends a buckle member 7034 toward the outer wall surface. The buckle member 7034 includes: a hinge 7035 provided on the right opening and closing member 7032, the hinge 7035 is hinged with a plate 7036, and the plate 7036 is provided with a buckle hole 7037 that matches the protrusion 7033.

[0065] In this example, box 1 consists of Figure 7 Change to Fig. 9 When the fastening member 7034 is fastened with the protrusion 7033 through the fastening hole 7037, the left opening and closing member 7031 is matched with the top of the right opening and closing member 7032. In this example, the left opening and closing member 7031 specifically matches the bending portion 7038 of the right opening and closing member 7032, and the cover is formed after being fastened and fixed. The advantage of this example is that the two sides are low and the middle is high, which can avoid water accumulation.

[0066] The structure of this example opens the cover structure when there is sufficient light to achieve irradiation and dehumidification. The top ventilation hole 101 can be set on the top to facilitate irradiation and dehumidification. The specific change process is as follows: Fig.10 Change to Figure 7 The process has been mentioned in the previous content and will not be repeated here.

[0067] Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
