[0002] A substation is a facility used to transform voltage and current in a power system, and to receive and distribute electrical energy. During the civil construction of a substation, the environmental quality at the construction site and in the surrounding area will decrease, and the dust content and humidity in the air will increase. During civil construction activities, it is necessary to control the dust and moisture generated during the construction project to ensure the safety of the substation.

[0003] Patent CN221244486U discloses a dehumidification and dust removal device for substation civil construction, including a support base, a box body fixed to the top of the support base, a support plate installed on the upper part of the box body, reserved through holes on both sides of the inside of the support plate, an air outlet at the bottom of one side of the box body, and a drain valve installed at the bottom of the other side of the box body.

[0004] However, this patent cannot adjust the suction power, thus failing to balance the demand ratio between dust removal and dehumidification. Utility Model Content

[0005] To overcome the shortcomings mentioned above, this utility model aims to provide a dehumidification and dust removal device for substation civil construction, which can change the ratio between dust removal and dehumidification by adjustment.

[0006] A dehumidification and dust removal device for substation civil construction includes: a trolley; an air inlet frame disposed on the trolley, the air inlet frame containing a dust collection bin; an adjusting bracket slidably connected to the air inlet frame; a dust removal filter element detachably connected to the adjusting bracket; an air suction assembly disposed on the top of the adjusting bracket; a dehumidification mechanism disposed on the top of the trolley, the dehumidification mechanism including an insulation shell and a condenser; and an air outlet assembly disposed on the top of the insulation shell.

[0008] Furthermore, the adjustment bracket is provided with support legs, which are slidably connected to the top of the air intake frame. The side wall of the support leg passes through the limiting slide, and the two support legs are connected by a connecting rod.

[0009] Furthermore, the limiting slide has a vertical array of positioning holes in the middle, and a positioning pin is inserted into the connecting rod, the positioning pin being able to pass through the positioning hole.

[0010] Furthermore, the adjustment bracket has a pull-out frame in the middle, and the dust removal filter element is slidably connected to the pull-out frame.

[0011] Furthermore, the suction assembly includes a fan, a drive motor, and a support rod. The top of the adjustment bracket is provided with a ventilation hole. The support rod is located on the side of the fixed end of the motor. The bottom of the support rod is fixedly connected to the top of the air intake frame. The fan is fixedly connected to the bottom of the motor.

[0012] Furthermore, the fan is located below the ventilation hole and above the dust removal filter element.

[0013] Furthermore, the condenser is located on the top of the insulation shell, the bottom of the insulation shell is fixed to the top of the air inlet frame, and the insulation shell surrounds the top of the adjustment bracket.

[0014] Furthermore, the condenser is provided with a water collection cover on the outside, the water collection cover is provided with a vent hole, and a water outlet pipe is connected to the water collection cover.

[0015] Furthermore, the air outlet assembly includes an air outlet duct and a sealing cap, the air outlet duct being located above the condenser, and the sealing cap being detachable from the top of the air outlet duct.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] ① There is a gap between the dust collector filter element and the top surface of the dust collection bucket. Air comes into contact with the dust collector filter element through the gap, and the dust collector filter element blocks the dust. The remaining air continues to move upward and pass through the dust collector filter element. When the adjustment bracket is moved upward, the gap between the dust collector filter element and the top of the air inlet frame increases, which reduces the airflow through the dust collector filter element, allowing the condenser above to fully dehumidify. When the gap decreases, the wind speed increases, and the dust removal efficiency increases. Attached Figure Description

Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0023] like Figure 1 , Figure 2 As shown, a dehumidification and dust removal device for substation civil construction includes: a trolley 1; an air inlet frame 2 mounted on the trolley 1, with a dust collection bin 21 inside the air inlet frame 2; an adjusting bracket 3 slidably connected to the air inlet frame 2; a dust removal filter element 4 detachably connected to the adjusting bracket 3; an air suction assembly 5 mounted on the top of the adjusting bracket 3; a dehumidification mechanism 6 mounted on the top of the trolley 1, the dehumidification mechanism 6 including an insulation shell 61 and a condenser 62; and an air outlet assembly 7 mounted on the top of the insulation shell 61.

[0024] The trolley 1 is used to move this device, making it easier to move in complex sites during substation construction. Using the trolley 1 reduces friction with the ground, making it easier and faster to move.

[0025] The air intake frame 2 has four side walls. One set of opposite side walls is equipped with an air intake grille 22, through which air from the substation can enter the air intake frame 2. Another side wall is equipped with a limiting slide 23, which connects the inside and outside of the air intake frame 2 at both ends. The fourth side wall is equipped with an opening, which is the side wall other than the air intake grille 22 and the limiting slide 23. The dust collection bin 21 enters the trolley 1 through the opening. When there is too much dust in the dust collection bin 21, it can be pulled out for emptying.

[0026] The adjustment bracket 3 is provided with a support leg 31. The height of the support leg 31 is greater than the height of the air intake frame 2. Therefore, the top of the adjustment bracket 3 is located above the air intake frame 2. The support leg 31 is slidably connected to the top of the air intake frame 2, thereby allowing the adjustment bracket 3 to move up and down. The side wall of the support leg 31 passes through the limiting slide 23. The two support legs 31 are connected by a connecting rod 32. The connecting rod 32 spans the outside of the limiting slide 23. By pulling the connecting rod 32 up and down, the height of the adjustment bracket 3 can be adjusted externally.

[0027] The middle part of the limiting slide 23 is a solid plate, and multiple positioning holes 231 are arranged vertically in the middle part of the limiting slide 23. A positioning pin 321 is inserted into the connecting rod 32, and the positioning pin 321 can pass through the positioning hole 231. In other embodiments, the end of the positioning pin 321 is provided with external thread, and the inside of the positioning hole 231 is provided with internal thread. The end of the positioning pin 321 can be screwed into the positioning hole 231, thereby limiting the height of the adjusting bracket 3 and preventing the adjusting bracket 3 from falling downward.

[0028] The adjustment bracket 3 has a pull-out frame 33 in the middle, and the dust filter element 4 is slidably connected to the pull-out frame 33, which allows for easy replacement when the dust filter element 4 is overloaded with dust. When the bottom of the support leg 31 contacts the bottom of the inner wall of the air inlet frame 2, the top surface of the pull-out frame 33 is at the same level as the top surface of the air inlet frame 2. At this time, the dust filter element 4 blocks the top outlet of the air inlet frame 2, and there is a gap between the dust filter element 4 and the top surface of the dust collection bin 21. Air comes into contact with the dust filter element 4 through the gap, and the dust filter element 4 blocks the dust. The remaining air continues to move upward and passes through the dust filter element 4. When the adjustment bracket 3 is moved upward, the distance between the dust filter element 4 and the top of the air inlet frame 2 increases, reducing the airflow through the dust filter element 4, which facilitates the condenser 62 above to fully dehumidify. When the distance decreases, the wind speed increases and the dust removal efficiency increases. Most of the blocked dust will fall into the dust collection bin 21 due to gravity when there is no suction.

[0029] The suction assembly 5 provides suction for the device. The suction assembly 5 includes a fan 51, a drive motor 52 and a support rod 53. The top of the adjustment bracket 3 is provided with a ventilation hole 34. The support rod 53 is located on the side of the motor fixing end. The support rod 53 is equivalent to the extension of the two sides of the motor fixing end. The bottom of the support rod 53 is fixed to the top of the air intake frame 2, thereby fixing the position of the motor. The fan 51 is fixed to the bottom of the motor. The output end of the motor drives the fan 51 to rotate and generate suction, thereby allowing air to pass through the dust removal filter element 4.

[0030] The fan 51 is located below the ventilation hole 34 and above the dust filter element 4. The fan 51 causes the air passing through the dust filter element 4 to continue to move upward and through the ventilation hole 34.

[0031] The inner wall of the insulation shell 61 is fitted to the outer wall of the support leg 31, thereby ensuring that all upward air movement passes through the dust filter element 4.

[0032] The condenser 62 is located on the top of the insulation shell 61, and the bottom of the insulation shell 61 is fixed to the top of the air inlet frame 2. The insulation shell 61 surrounds the top of the adjustment bracket 3. The air entering the insulation shell 61 causes moisture to condense at the condenser tube, thereby achieving the effect of dehumidification.

[0033] A water collection cover 63 is provided on the outside of the condenser 62. The side wall of the water collection cover 63 is fixedly connected to the inner top wall of the insulation shell 61. The water collection cover 63 is provided with a vent hole 631 and a water outlet pipe 632 is connected to the water collection cover 63. The vent hole 631 facilitates contact between air and the condenser tube. The condenser tube condenses the moisture in the air into water droplets that drip into the water collection cover 63. The water in the water collection cover 63 is discharged outward from the water outlet pipe 632.

[0034] The air outlet assembly 7 includes an air outlet duct 71 and a sealing cap 72. The air outlet duct 71 is located above the condenser 62, and the air passing through the condenser 62 is discharged from the air outlet duct 71, reducing the dust and humidity of the discharged air. The sealing cap 72 is removable from the top of the air outlet duct 71 and is closed when the device is not in use to prevent dust from falling in.

[0035] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
