Description

Technical Field

[0001] The present invention relates to the field of drying equipment, and particularly relates to a terminal box condensation removal drying equipment and a using method thereof. Background Art

[0002] A terminal box is a device used for electrical connection and protection, usually used for the connection of electrical equipment, instruments or cables. When the terminal box is used outdoors, due to the change of temperature difference, the air temperature will change, and then the water vapor in the air will condense on the inner wall of the terminal box, causing condensation in the terminal box. If this phenomenon is not dealt with in time, when the condensed water drips onto the electrical appliance under the action of gravity, it will cause a short circuit of the equipment.

[0003] In order to solve the condensation problem of the terminal box, a drying equipment is adopted in the prior art. The equipment mainly consists of a box body, a dehumidification mechanism and an air extraction mechanism. The air extraction mechanism and the dehumidification mechanism are both arranged inside the box body. The air extraction mechanism is responsible for pumping the humid gas inside the terminal box to the dehumidification mechanism to remove the water vapor in the air. During the working process of the drying equipment, the dehumidification mechanism makes the air dry by removing the water vapor, and the removed water vapor condenses into water droplets and is directly discharged out of the box body through a pipeline. However, this discharge method has a significant defect, that is, the accumulated water discharged outside will cause the humidity of the environment where the terminal box is located to increase. This increase in humidity not only affects the real-time detection of the temperature and humidity inside the terminal box by the drying equipment, but also makes the humidity change of the environment around the terminal box slow. Therefore, in order to maintain the dry state of the terminal box, the drying equipment has to work continuously, resulting in the shortening of the service life of the equipment and unnecessary energy waste. In view of this, the present solution proposes a terminal box condensation removal drying equipment and a using method thereof to solve the above problems. Summary of the Invention

[0028] Technical effects and advantages of the present invention:

[0029] (1) The present invention is provided with an air guiding and water collection mechanism. Firstly, through the connection and cooperation of the air guiding part and the water collection part, the water vapor in the removed moisture is collected into the water collection part. At the same time, in order to facilitate the removal of the water vapor in the moisture, through the structural cooperation of the air guiding part and the dehumidification mechanism, the moisture can be more accurately and stably guided to the dehumidification mechanism for dehumidification. At the same time, in cooperation with the structural setting of the dehumidification mechanism, the accumulated water vapor can fall into the water collection part faster for collection. In this way, the rate of water droplet collection is improved, and at the same time, the water droplets on the surface of the dehumidification mechanism are separated more quickly, enabling the continuous dehumidification work of the dehumidification mechanism to be carried out stably, improving the dehumidification efficiency. At the same time, after collecting the water in the water vapor, the environmental humidity near the terminal box drops significantly, effectively avoiding the condensation phenomenon of the terminal box.

[0030] (2) The present invention is provided with a water level warning part in the water collection part. Through the structural setting of the water level warning part, the water level in the water collection part can be warned. And under the structural setting of the water level warning part, the water collection part can be effectively sealed to prevent the water in the water collection part from leaking out. At the same time, after the water level warning signal is sent to the controller, the controller controls the on-off of the air extraction mechanism and the dehumidification mechanism, and can use the controller to display the water level warning, so as to assist the operator in cleaning the water, ensuring the stable and effective operation of the device.

[0042] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0043] Embodiment 1, the present invention provides a kind of terminal box condensation removal and drying equipment as Figures 1-10 shown, including an installation box 1, a sealing cover 2 is arranged on the front surface of the installation box 1, installation plates 101 are fixedly connected to both the top and the bottom of the installation box 1, an air exhaust port 102 is opened at the bottom of the installation box 1 and at one end far away from the sealing cover 2, and an air inlet 201 is opened at the bottom of the sealing cover 2.

[0044] It should be noted that the sealing cover 2 is detachably installed on the front surface of the installation box 1 by screws, and in the setting of this solution, the inner wall of the installation box 1 is divided into upper and lower parts, separated by a partition in the middle, and the side wall of the space at the bottom of the installation box 1 has a convex structure for use as a containing tank structure.

[0045] It further includes:

[0046] The air extraction mechanism is arranged at the bottom of the installation box 1 and near one end of the closed cover 2. The air extraction mechanism is used to suck the moisture in the terminal box into the installation box 1. The air extraction mechanism is arranged at the air inlet 201. The air extraction mechanism sucks through the air inlet 201 to allow the moisture in the terminal box to enter the installation box 1;

[0047] Specifically, the air extraction mechanism includes a blocking frame 4. The blocking frame 4 is fixedly connected to the side of the closed cover 2 close to the installation box 1, and the blocking frame 4 is installed at the air inlet 201. A suction fan 401 is arranged in the blocking frame 4. The suction fan 401 sucks gas through the air inlet 201 to the air guiding part.

[0048] It should be noted that the air inlet 201 of the closed cover 2 is opened at the bottom, and the opening range is smaller than that of the blocking frame 4, so as to ensure that the air entering the installation box 1 through the air inlet 201 all passes through the inside of the blocking frame 4. The end corners of the blocking frame 4 are fixedly connected to the bottom of the closed cover 2 by screws. Through the structural setting of the blocking frame 4, the suction fan 401 can be shielded and protected. At the same time, with such a structural setting, the blocking frame 4 is used as a blocking net structure to filter the gas entering the installation box 1 and block the flocs mixed in the air. Therefore, during the use of the device, it is necessary to frequently brush the surfaces of the air inlet 201 and the blocking frame 4 to ensure the smoothness of the air inlet channel.

[0049] The air guiding and water collecting mechanism is arranged at the bottom of the installation box 1. The air guiding and water collecting mechanism includes an air guiding part and a water collecting part. The air guiding part is arranged above the water collecting part. The air guiding part is connected to the exhaust end of the air extraction mechanism in a through manner. A water level warning component is arranged in the water collecting part. The exhaust port 102 is connected to the exhaust end of the air guiding part in a through manner. The exhaust port 102 is used to discharge dry gas;

[0050] The dehumidification mechanism is inserted and connected in the air guiding part. The dehumidification mechanism is used for dehumidifying the sucked moisture;

[0051] The controller 3 is arranged on the top of the installation box 1. The output end of the controller 3 is electrically connected to the air extraction mechanism and the dehumidification mechanism. The receiving end of the controller 3 is electrically connected to the sending end of the water level warning component. The controller 3 is used for starting and stopping control of the air extraction mechanism, cyclic control of the dehumidification mechanism, and display of the water level warning signal. A wiring terminal 301 is arranged at the receiving end of the controller 3. The wiring terminal 301 is used for electrically connecting a temperature and humidity sensor. The temperature and humidity sensor is used to detect the temperature and humidity changes in the terminal box and send the detection signal into the controller 3. The controller 3 is used for starting and stopping control of the air extraction mechanism according to the temperature and humidity signal.

[0052] Specifically, the air guiding part includes an air guiding cover 5. A wind guiding through groove 501 is formed in the middle of the air guiding cover 5. The wind guiding through groove 501 is provided with an air inlet section and an air outlet section. The dehumidifying mechanism is inserted and connected into the wind guiding through groove 501. The air inlet section is arranged in a downward inclined shape, and a water collecting groove 502 is formed at the bottom end of the air outlet section. The water collecting groove 502 is used to guide condensed water into the water collecting part.

[0053] It should be noted that the air guiding cover 5 is an overall sealed box structure. The side cross-section of this box structure is similar to an "L" shape. Its air inlet section is an inclined downward channel, which is convenient for guiding the air flow to be pumped downward. At the same time, it is convenient for water droplets to condense and form in the air inlet section and then fall and be collected more quickly under the action of gravity. The discharge end is a horizontal straight channel for discharging the air after drying treatment. The top of the water collecting groove 502 is in a concave structure, which is convenient for collecting the falling water droplets.

[0054] Specifically, the water collecting part includes a water collecting tank 6. A water inlet is formed at the top end of the water collecting tank 6. A through pipe 503 is arranged at the bottom end of the air guiding cover 5 and at the position of the water collecting groove 502. The through pipe 503 penetrates through the water inlet and is inserted into the water collecting tank 6. The water level warning member is inserted and connected at the water collecting tank 6 and the water collecting groove 502.

[0055] It should be noted that the water inlet of the water collecting tank 6 is circular. The outer wall size of the through pipe 503 matches the outer wall size of the water inlet. The outer wall of the through pipe 503 can be made of flexible rubber material. Therefore, after the through pipe 503 is inserted into the water inlet, the through pipe 503 is tightly attached to the inside of the water inlet through extrusion deformation. In this way, while ensuring the insertion connection between the through pipe 503 and the water inlet, the deformation of the outer wall of the through pipe 503 can be used to squeeze and fit the inner wall of the water inlet, and the two form an extrusion seal, so as to ensure that when the water collecting tank 6 collects water, the water will not overflow from the water inlet.

[0056] Specifically, the water level warning member includes:

[0057] An upward floating float 602 is inserted and connected into the water collecting tank 6. A through rod 604 is arranged at the top end of the upward floating float 602. The through rod 604 is inserted and connected with the inner wall of the through pipe 503. The rod wall of the through rod 604 is provided with a first extrusion block 605 and a second extrusion block 606 along the vertical direction.

[0058] It should be noted that the upper floating body 602 is made of foam plastic, and the density of this material is lower than that of water. Therefore, in the water body, the upper floating body 602 always floats on the top surface of the water body. When condensate is gradually collected in the collecting tank 6, the condensate enters the collecting tank 6 after passing through the water inlet and then through the interpenetrating pipe 503. After the water body is collected in the collecting tank 6, it supports the upper floating body 602 upward. The interpenetrating rod 604 is of a cylindrical structure and is prepared with a hollow low-density structure to reduce the downward pressure on the upper floating body 602, so that the upper floating body 602 can float better in the water body.

[0059] The travel switch 505 is interpenetratingly connected to the inner wall of the collecting tank 502, and the output end of the travel switch 505 is electrically connected to the receiving end of the controller 3. The travel switch 505 is triggered by the extrusion of the first extrusion block 605 and the second extrusion block 606 after moving upward through the interpenetrating rod 604. The controller 3 receives the trigger signals of the travel switch 505 twice for water level early warning and water level warning display.

[0060] It should be noted that the travel switch 505 is arranged in the collecting tank 502 and on the side close to the air outlet 102. The first extrusion block 605 and the second extrusion block 606 are on the same side as the travel switch 505. When the upper floating body 602 moves upward under the support of the water body, the interpenetrating rod 604 drives the first extrusion block 605 and the second extrusion block 606 to move upward synchronously with the upper floating body 602. When the first extrusion block 605 and the second extrusion block 606 pass through the position where the travel switch 505 is located, they squeeze and touch the travel switch 505, thereby triggering the travel switch 505. The first extrusion block 605 and the second extrusion block 606 respectively trigger the travel switch 505, and the travel switch 505 sends the trigger signal to the controller 3. A warning light and a buzzer are added at the controller 3. When the first extrusion block 605 squeezes the travel switch 505 to trigger it, the controller 3 receives the early warning for the first time, and at this time the warning light lights up. When the second extrusion block 606 squeezes the travel switch 505 to trigger it, the controller 3 receives the trigger signal for the second time, and at this time the buzzer is activated. Moreover, when the controller 3 receives the signal of the travel switch 505 and triggers the warning light and the buzzer, a single-cycle mode is adopted, that is, two signals of the travel switch 505 form a cycle.

[0061] Furthermore, a limiting chute 601 is opened on the side wall of the collecting tank 6, a limiting slide rod 603 is fixedly connected to the bottom of the upper floating body 602, and one end of the limiting slide rod 603 away from the upper floating body 602 is interpenetratingly connected in the limiting chute 601. A closed groove 504 is opened at the bottom end of the interpenetrating pipe 503 and penetrating through the bottom pipe orifice, and the shape and size of the closed groove 504 are adapted to the shape and size of the upper floating body 602.

[0062] It should be noted that by restricting the opening of the sliding groove 601 and the insertion and cooperation of the sliding rod 603, the upward floating float 602 can stably move in the vertical direction in the water collecting tank 6. And through the setting of the closed groove 504, when the water collection in the water collecting tank 6 reaches the warning value, the top of the upward floating float 602 penetrates into the closed groove 504 to block the insertion pipe 503, so that water cannot enter the water collecting tank 6.

[0063] It should be noted that

[0064] Specifically, the dehumidification mechanism includes:

[0065] A compressor 7, which is arranged in the installation box 1;

[0066] An evaporator 8, which is arranged in the air inlet section, and the evaporator 8 is synchronously inclined downward with the air inlet section. The feeding end of the evaporator 8 is connected to the discharging end of the compressor 7 in a through manner. The outer wall of the evaporator 8 is provided with condensation fins 801 in an array distribution;

[0067] A condenser 9, which is arranged in the air outlet section, and the condenser 9 is arranged vertically. A capillary tube 10 is arranged between the feeding end of the condenser 9 and the discharging end of the evaporator 8. The discharging end of the condenser 9 is connected to the feeding end of the compressor 7 in a through manner. The outer wall of the condenser 9 is provided with contact fins 901 in an array distribution.

[0068] It should be noted that the dehumidification mechanism is composed of the compressor 7, the evaporator 8 and the condenser 9 to form a condensation dehumidification structure. In the setting of this mechanism, the compressor 7 compresses the low-temperature and low-pressure gaseous refrigerant into a superheated steam at high temperature and high pressure (80 - 120 °C). And when the compressor 7 is structurally set, its built-in shock-absorbing bracket and heat dissipation air duct have a working pressure range of 0.8 - 2.5 MPa; the evaporator 8 is inclined and installed in the air inlet section, and adopts a 30° inclination angle design. The condensation fins 801 adopt a copper tube-aluminum fin structure (fin pitch 2.5 mm). The liquid refrigerant is completely vaporized at the evaporator 8, absorbing the sensible heat and latent heat of the air (the temperature drops below the dew point). In this way, the moisture in the terminal box drawn into the air guiding through groove 501 condenses into water droplets on the surface of the condensation fins 801; the condenser 9 is vertically installed in the air outlet section, and the contact fins 901 are arranged in a V-shaped fin matrix. A forced convection fan (wind speed 1.5 - 3 m / s) is provided, and the high-temperature gaseous refrigerant is condensed into a subcooled liquid here, releasing the condensation latent heat (2200 kJ / kg).

[0069] Embodiment 2, the present invention provides a method for using a terminal box condensation removal and drying device, which adopts the terminal box condensation removal and drying device of Embodiment 1. The using method includes the following steps:

[0070] First step, first install the device at the inner wall position near the top of the terminal box, then install the sensing end of the temperature and humidity sensor in the terminal box, and at the same time electrically connect the communication end of the temperature and humidity sensor to the receiving end of the controller 3;

[0071] It should be noted that the entire device is installed in the terminal box through the structure of the mounting plate 101, and the device is electrically connected to the conduction circuit in the terminal box. At the same time, the temperature and humidity sensor is electrically connected to the controller 3 through the terminal 301 to detect the temperature and humidity in the terminal box in real time.

[0072] Second step, when the temperature and humidity sensor sends the detected temperature and humidity signals into the controller 3, the controller 3 energizes and starts the air extraction mechanism and the dehumidification mechanism according to the humidity signal. After the air extraction mechanism starts, it sucks the humid air in the terminal box into the installation box 1, and conducts suction and guidance through the air guiding part. At the same time, the dehumidification mechanism dehumidifies and heats the moisture passing through the air guiding part;

[0073] It should be noted that when the detected value transmitted by the temperature and humidity sensor reaches the starting value of the controller 3, the controller 3 controls the start of the exhaust fan 401 and the compressor 7. The exhaust fan 401 sucks the moisture in the terminal box into the installation box 1 through the air inlet 201. At this time, under the shielding and guidance of the air guiding cover 5, the moisture flows along the air guiding through groove 501 and is discharged from the air outlet 102.

[0074] Third step, after the moisture dehumidified by the dehumidification mechanism condenses into water droplets, they adhere to the evaporator 8 of the dehumidification mechanism, and then the water droplets gather and fall due to gravity into the water collection part for collection;

[0075] It should be noted that when the moisture passes through the evaporator 8 and contacts the condensation fin 801 to condense into beads, under the action of gravity and the blowing of wind, the condensed water droplets fall to the bottom of the air guiding through groove 501, and pass through the water collection tank 502 and the insertion pipe 503, and are collected in the water collection tank 6.

[0076] Fourth step, the water collection part continuously collects the condensed water droplets, and makes the floating buoy 602 of the water level warning part float under the action of buoyancy. At the same time, it triggers the water level warning through the insertion with the air guiding part, and the controller 3 displays the water level warning according to the received warning signal.

[0077] It should be noted that as the condensate collected in the water collecting tank 6 gradually increases, the water body gradually floats up and supports the upward floating float 602. Driven by the upward floating float 602, the insertion rod 604 moves vertically upward along the insertion rod 604. At the same time, the first extrusion block 605 and the second extrusion block 606 move upward synchronously with the insertion rod 604. During the upward movement of the first extrusion block 605 and the second extrusion block 606, different warnings are triggered after they touch the travel switch 505 by extrusion. At the same time, the controller 3 controls the on / off of the exhaust fan 401 and the compressor 7 according to the received signal.

[0078] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not intended to limit the present invention. Although the present invention 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 perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
