Description

Technical Field

[0001] This utility model relates to the field of power system technology, and in particular to a water collection mechanism and dehumidification device. Background Technology

[0002] Substation terminal boxes are an important component of substations, primarily used for wiring and branching electrical equipment, connecting power lines of different voltage levels into the substation. Through the interconnection of terminal boxes, the commissioning of electrical equipment can be achieved, while ensuring lossless and stable power transmission within the substation.

[0003] Substation terminal boxes are typically equipped with intelligent dehumidification and heat dissipation devices. These devices actively dissipate heat by driving fans, which not only significantly improves the efficiency of internal air circulation and effectively reduces the temperature difference between the inside and outside of the terminal box, but also intelligently responds to climate changes. Especially during the rainy season, the device can collect temperature and humidity data inside and outside the terminal box in real time and promptly activate the built-in heating function to completely eliminate condensation caused by high humidity, thereby ensuring that secondary equipment is always in a safe and reliable operating state.

[0004] The aforementioned intelligent dehumidification and heat dissipation device dehumidifies and dissipates heat based on the operating principle of an air conditioner. Therefore, condensation will be generated during operation, and this condensation needs to be discharged through a drain pipe. However, during long-term operation, dust from the surrounding environment will enter the drain pipe along with the condensation. Over time, this may lead to excessive dust accumulation in the drain pipe, causing blockage and resulting in poor drainage. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of this application, to avoid obscuring the purpose of these documents; however, such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] In view of the problem of excessive dust entering and clogging of existing drainage pipes, this utility model is proposed.

[0007] Therefore, one of the objectives of this utility model is to provide a water collection mechanism.

[0008] To solve the above-mentioned technical problems, the present invention provides the following technical solution: including a pull-out water collection tank, wherein a water-holding cavity is formed inside the pull-out water collection tank, a liquid outlet is provided on the bottom plate at the bottom of the water collection tank, and a filter screen is provided in the inner cavity of the water-holding cavity.

[0010] The beneficial effects of the water collection mechanism described in this utility model are as follows: after the water dripping from the fins of the evaporator enters the pull-out water collection tank, it will be filtered by the filter screen. The filter screen can intercept impurities and dust, preventing the drain pipe below from being blocked by impurities or dust.

[0011] In actual use, existing substation terminal boxes still have the problem of drainage pipes becoming clogged due to excessive dust accumulation during long-term use, resulting in poor drainage.

[0012] To solve the above-mentioned technical problems, this utility model also provides the following technical solution: a dehumidification and heat dissipation component, including a housing and an evaporator inside the housing; the housing is installed on the cabinet door of a substation terminal box; a receiving component is disposed on the housing and located below the evaporator, a water tank cavity is formed in the middle of the receiving component, the outer side of the water tank cavity penetrates the outer wall of the housing, a drain hole is provided at the bottom of the water tank cavity, and the liquid outlet is aligned with the drain hole; a floating switch is disposed in the water-holding cavity and located above the filter screen; an alarm component is disposed in a reserved slot in the housing and corresponds to the floating switch; the floating switch controls the opening and closing state of the alarm component.

[0013] In a preferred embodiment of the dehumidification device of this utility model, a drain pipe is connected to the bottom of the drain hole, and the end of the drain pipe away from the drain hole extends beyond the bottom of the housing.

[0014] As a preferred embodiment of the dehumidification device of this utility model, the dehumidification and heat dissipation components further include a micro compressor, a turbine fan, a condenser, and a throttling device; the housing is installed at the reserved window of the cabinet door of the substation terminal box, the upper part of the inner side wall of the housing is provided with an air inlet, and the lower part is provided with an air outlet; the micro compressor is connected in sequence with the condenser, the throttling device, and the evaporator to form a circuit, and all four are located in the housing.

[0015] As a preferred embodiment of the dehumidification device of this utility model, an outer cover is further provided on the outside of the housing; the housing is fixed to the inside of the reserved window of the cabinet door by mounting screws, and the outer cover is fixed to the outside of the reserved window of the cabinet door by mounting screws.

[0016] In a preferred embodiment of the dehumidification device of this utility model, the alarm component includes a warning light, a power supply, a first contact, and a second contact; one end of the warning light is connected to the first contact via a wire, and the other end is connected to the power supply and the second contact in sequence via a wire, and the first contact and the second contact are disconnected from each other.

[0017] In a preferred embodiment of the dehumidification device of this utility model, the floating switch includes a cylinder, a float, a bracket, a third contact, a fourth contact, and a connecting conductor; the cylinder is fixed to the inner wall of the front baffle, and the top of the cylinder is open, while the bottom is provided with a liquid inlet; the float is disposed in the cylinder, and the float can move up and down along the cylinder but cannot fall out from the liquid inlet at the bottom of the cylinder; the bracket is fixed to the top of the float; the third contact and the fourth contact are both disposed on the top of the bracket and correspond to the first contact and the second contact, respectively; the connecting conductor is disposed on the bracket and conducts electricity between the third contact and the fourth contact.

[0018] In a preferred embodiment of the dehumidification device of this utility model, the front baffle has a flange relative to the first side plate, the second side plate and the bottom plate, and a waterproof adhesive strip is attached to the inner side of the flange.

[0019] In a preferred embodiment of the dehumidification device of this utility model, guide strips are provided on the outer surfaces of the first side plate and the second side plate; guide grooves are provided on the left and right sides of the water tank cavity corresponding to the guide strips.

[0020] The beneficial effects of the dehumidification device described in this utility model are as follows: When the device is turned on, the turbine fan will form an internal circulation, drawing in the humid air in the substation terminal box through the air inlet. The water vapor in the air is condensed into water by the evaporator and adsorbed onto the fins of the evaporator, forming water droplets. These droplets then drip down the fins into the pull-out water collection tank below, and are discharged out of the casing through the drain pipe into the sewer. In this way, the humid air becomes dry air. After that, the air is heated and dissipated by the condenser, and then dry air is blown out from the air outlet. This cycle repeats, reducing the humidity of the air in the substation terminal box, eliminating condensation caused by high humidity, and ensuring the safe and reliable operation of the equipment.

[0021] When the dust trapped by the filter reaches a certain level, a layer of dust may accumulate on the filter surface, causing the filter to become clogged. At this time, the water dripping from the evaporator fins cannot continue to fall or falls very slowly, and will accumulate on the filter, causing more and more water to accumulate above the filter. As the water level rises, water will enter from the liquid inlet at the bottom of the float switch cylinder, and then push the float to move upward. Once the water level rises to a certain level, when the float moves upward and contacts the dehumidifier, the third contact contacts the first contact, and the fourth contact contacts the second contact, which will make the first contact and the second contact conductive, thus forming a circuit in the dehumidifier and issuing an alarm. After receiving the alarm, the staff can pull out the pull-out water collection tank from the housing component, clean the filter, and then put the pull-out water collection tank back into the housing component to restore normal operation.

[0022] Therefore, the filter screen in this utility model can prevent the drain pipe from becoming clogged, solving the problem of poor drainage caused by excessive dust entering the drain pipe during long-term use. At the same time, when the filter screen accumulates too much dust, it will also issue an alarm to remind staff to clean the filter screen. Attached Figure Description

[0034] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0035] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0036] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that excludes other embodiments.

[0037] Example 1

[0038] See Figures 1 to 10 The present invention provides a water collection mechanism, which includes: a pull-out water collection tank (300), the pull-out water collection tank (300) having a water holding cavity (3a) inside, the bottom plate (350) at the bottom of the water collection tank (300) having a liquid outlet (3b), and a filter screen (360) being provided in the inner cavity of the water holding cavity (3a).

[0039] See Figure 6The pull-out water collection tank 300 includes a front baffle 310, a first side plate 320, a second side plate 330, and a rear baffle 340. The front baffle 310, the first side plate 320, the second side plate 330, the rear baffle 340, and the bottom plate 350 together form the water-holding cavity 3a.

[0040] See Figure 8 The front baffle 310 has flanges 311 formed relative to the first side plate 320, the second side plate 330, and the bottom plate 350. A waterproof adhesive strip 370 is attached to the inner side of each flange 311. When the pull-out water collection tank 300 is fully inserted into the water tank cavity 2a, the waterproof adhesive strip 370 and the corresponding recess 11a on the outer wall of the housing 110 (see...) Figure 10 They are closely connected.

[0041] Therefore, when the pull-out water collection tank 300 is fully inserted into the water tank cavity 2a, the waterproof strip 370 can prevent water from leaking out from the gaps.

[0042] Furthermore, the flange 311 is magnetically attached to the housing 110. For example, the flange 311 is made of magnet and can be attached to the steel plate of the housing 110.

[0043] The magnetic attraction method ensures that the waterproof strip 370 is tightly abutted against the recess 11a of the housing 110 to prevent leakage. It also ensures that the pull-out water collection tank 300 is easy to put on and take off, without the need for screws. It can be removed simply by pulling it out.

[0044] See Figure 6 The outer surfaces of both the first side plate 320 and the second side plate 330 are provided with guide strips 3c. Guide grooves 2a1 are provided on both the left and right sides of the water tank cavity 2a, corresponding to the guide strips 3c. The pull-out water collection tank 300 is guided to move relative to the water tank cavity 2a through the interlocking of the guide strips 3c and the guide grooves 2a1.

[0045] See Figure 7 The outer wall of the front baffle 310 is provided with a handle groove 312 for easy hand pulling of the pull-out water collection tank 300.

[0046] When taking out or putting in the pull-out water collection tank 300, simply hold the handle groove 312 to pull the pull-out water collection tank 300 out of the water tank cavity 2a, or put it back into the water tank cavity 2a. When putting it back, make sure that the guide strips 3c on the left and right sides of the pull-out water collection tank 300 are aligned with the guide grooves 2a1 on the inner wall of the water tank cavity 2a.

[0047] Example 2

[0048] The device includes a dehumidification and heat dissipation component 100, a receiving component 200, a pull-out water collection tank 300, a floating switch 400, and an alarm component 500.

[0049] The dehumidification and heat dissipation component 100 includes a housing 110 and a miniature compressor 120, a turbine fan 130, a condenser 140, a throttling device 150, and an evaporator 160 disposed within the housing 110. (See also...) Figures 1 to 3 The housing 110 is installed at the reserved opening a1 of the cabinet door a of the substation terminal box. The upper part of the inner wall of the housing 110 is provided with an air inlet 111, and the lower part with an air outlet 112. (See also...) Figure 4 The micro compressor 120 is sequentially connected to the condenser 140, the throttling device 150, and the evaporator 160 to form a circuit. The turbine fan 130 is disposed in the airflow channel between the evaporator 160 and the condenser 140, wherein the evaporator 160 corresponds to the air inlet 111, and the condenser 140 corresponds to the air outlet 112. When the turbine fan 130 operates, it draws in air through the air inlet 111, drives the air to flow sequentially over the outer surfaces of the evaporator 160 and the condenser 140, and then discharges it through the air outlet 112, forming an internal circulation. See also... Figure 3 The outer side wall of the housing 110 is also provided with an external circulation air inlet 113 and an external circulation air outlet 114 for air intake to dissipate heat from the dehumidification and heat dissipation components.

[0050] It should be noted that the micro compressor 120 works on a similar principle to the compressor in an air conditioner. The low-pressure vapor of the refrigerant in the refrigeration system is drawn in by the micro compressor 120 and compressed into high-pressure vapor before being discharged to the condenser. At the same time, the air drawn in by the fan outside the cabinet flows through the condenser, carrying away the heat released by the refrigerant and causing the high-pressure refrigerant vapor to condense into a high-pressure liquid.

[0051] It should also be noted that the throttling device 150 operates on the same principle as the throttling device in an air conditioner. High-pressure liquid is injected into the evaporator after passing through the throttling device 150, where it evaporates under corresponding low pressure, absorbing heat from the surrounding environment. Simultaneously, the fan inside the cabinet continuously exchanges heat with air through the evaporator fins, sending the cooled air into the cabinet. This continuous air circulation within the cabinet achieves the purpose of lowering the temperature.

[0052] See Figures 5 to 7 The receiving component 200 is attached to the housing 110 and located below the evaporator 160. Specifically, the receiving component 200 is disposed on the inner wall of the outer side of the housing 110 (i.e., Figure 3 On the inner wall of the surface shown).

[0053] See Figure 6The receiving component 200 has a water tank cavity 2a formed in its middle, the outer side of which penetrates the outer wall of the housing 110, and a drain hole 2b is provided at the bottom of the water tank cavity 2a. See also... Figure 7 The bottom of the drain hole 2b is connected to a drain pipe 600, and the end of the drain pipe 600 away from the drain hole 2b extends to the outside of the bottom of the housing 110 (not shown in the figure).

[0054] See Figures 5 to 7 The pull-out water collection tank 300 is arranged in the water tank cavity 2a, and the pull-out water collection tank 300 can be completely inserted into the water tank cavity 2a (e.g., Figure 5 As shown), it can also be pulled out from the outside of the housing 110 from the water tank cavity 2a (as shown). Figure 6 and Figure 7 (As shown). The pull-out water collection tank 300 forms a water-holding cavity 3a with four sides enclosed and an open top, and a bottom plate 350. The bottom plate 350 at the bottom of the water-holding cavity 3a is provided with a liquid outlet 3b (see...). Figure 7 The water-holding cavity 3a is equipped with a filter screen 360 (see...). Figure 6 When the pull-out water collection tank 300 is fully inserted into the water tank cavity 2a, the water-holding cavity 3a can receive water dripping from the fins of the evaporator 160, and the liquid outlet 3b is aligned with the drain hole 2b. The filter screen 360 has small mesh openings, which can block small particles, or, when there is a large amount of dust in the water, can also block excessive dust, preventing it from entering the drain pipe 600 below and causing blockage.

[0055] Example 3

[0056] See Figure 8 and Figure 9 The floating switch 400 is installed in the water-filled cavity 3a and located above the filter screen 360. The contacts of the floating switch 400 can float upward as the liquid level in the water-filled cavity 3a rises.

[0057] See Figure 5 and Figure 6 The alarm component 500 is mounted on the housing 110 and corresponds to the float switch 400. When the pull-out water collection tank 300 is fully inserted into the water tank cavity 2a, if the contact of the float switch 400 floats upward to contact the alarm component 500, the alarm component 500 will issue an alarm.

[0058] In the above technical solution, the working principle of the dehumidification and heat dissipation component 100 is as follows:

[0059] When the system is running, the internal circulation system draws in humid air from the substation terminal box through the air inlet 111. The air passes through the evaporator 160, where water vapor is condensed into water droplets that are adsorbed onto the fins of the evaporator 160. These droplets then drip down the fins into the pull-out water collection tank 300 below, and are discharged from the casing 110 through the drain pipe 600 into the sewer. In this way, the humid air becomes dry air. After being heated and cooled by the condenser 140, the dry air is blown out from the air outlet 112. This cycle repeats, reducing the humidity of the air inside the substation terminal box, eliminating condensation caused by high humidity, and ensuring the safe and reliable operation of the equipment.

[0060] Considering that a wind direction from the outside to the inside might cause a short circuit in the control circuitry of the substation terminal box, the turbine fan 130 should blow air from the inside to the outside. (See [reference]). Figure 4 An arrow pointing in the direction of the stroke.

[0061] See Figure 5 and Figure 6 The floating switch 400 is installed on the inner wall of the front baffle 310.

[0062] See Figure 10 The alarm component 500 is installed in a reserved slot in the housing 110. The alarm component 500 includes an alarm light 510, a power supply, a first contact 520, and a second contact 530. One end of the alarm light 510 is connected to the first contact 520 via a wire, and the other end is connected to the power supply and the second contact 530 in sequence via wires, with the first contact 520 and the second contact 530 being disconnected from each other. When the contacts of the floating switch 400 float upwards to contact the alarm component 500, the first contact 520 and the second contact 530 become conductive, and the alarm light 510 emits an alarm signal.

[0063] The power supply can be obtained by connecting wires to electrical components inside the substation terminal box.

[0064] The alarm component 500 may also be equipped with a buzzer, which can simultaneously sound an alarm when the warning light 510 emits a light alarm. Furthermore, in a preferred embodiment, the alarm component 500 can also communicate with a backend system, transmitting a signal to the backend system when an alarm is triggered, allowing staff to be promptly notified of the alarm.

[0065] Further, see Figure 9 The floating switch 400 includes a cylinder 410, a float 420, a bracket 430, a third contact 440, a fourth contact 450, and a connecting conductor 460.

[0066] The cylinder 410 is fixed to the inner wall of the front baffle 310, and the top of the cylinder 410 is open, and the bottom is provided with a liquid inlet 411.

[0067] The float 420 is disposed in the cylinder 410. The float 420 can move up and down along the cylinder 410 and cannot fall out from the liquid inlet 411 at the bottom of the cylinder 410.

[0068] The bracket 430 is fixed to the top of the floating body 420.

[0069] The third contact 440 and the fourth contact 450 are both located on the top of the bracket 430 and correspond to the first contact 520 and the second contact 530, respectively.

[0070] The connecting conductor 460 is disposed on the bracket 430 and conducts the third contact 440 and the fourth contact 450.

[0071] The float 420, support 430, third contact 440, fourth contact 450, and connecting conductor 460 together have a density less than that of water. When the float switch 400 floats upward to contact the alarm component 500, the third contact 440 contacts the first contact 520, and the fourth contact 450 contacts the second contact 530, thus making the first contact 520 and the second contact 530 conductive.

[0072] The working principle of the above-mentioned floating switch 400 is as follows:

[0073] Water dripping from the fins of the evaporator 160 enters the pull-out water collection tank 300 and is filtered by the filter screen 360. The filter screen 360 intercepts impurities and dust, preventing the drain pipe 600 below from being clogged by impurities or dust. When the dust intercepted by the filter screen 360 reaches a certain level, a layer of dust may accumulate on its surface, causing the filter screen 360 to become clogged. At this point, the water dripping from the fins of the evaporator 160 cannot continue to fall or falls very slowly, thus accumulating on the filter screen 360, causing more and more water to accumulate above the filter screen 360. As the water level rises, water enters through the inlet 411 at the bottom of the float switch 400 cylinder 410, pushing the float 420 upwards. Once the water level reaches a certain point, when the float 420 contacts the alarm component 500, the third contact 440 contacts the first contact 520, and the fourth contact 450 contacts the second contact 530. This causes the first contact 520 and the second contact 530 to conduct, thus creating a circuit in the alarm component 500 and triggering an alarm. After receiving the alarm notification, staff can remove the pull-out water collection tank 300 from the receiving component 200 (see...). Figure 6 Then clean the filter screen 360. After cleaning, reinsert the pull-out water collection tank 300 into the receiving component 200 to restore normal operation.

[0074] In order to prevent the float 420 from deviating when moving up and down, which would cause the corresponding contact points to fail to make contact, this utility model provides a limiting protrusion on the inner wall of the cylinder 410 and a corresponding limiting groove on the outer wall of the float 420. The limiting protrusion is embedded in the limiting groove, so that the float 420 will not deflect when moving up and down.

[0075] In a preferred embodiment, see Figure 1 An outer cover 170 is also provided on the outer side of the housing 110. Ear plates are provided around the perimeter of the housing 110, and these ear plates are fixed to the inner side of the reserved opening a1 of the cabinet door a by mounting screws 700. The outer cover 170 is fixed to the outer side of the reserved opening a1 of the cabinet door a by the same mounting screws 700. During fixing, a sealing ring 800 is provided between the ear plates around the housing 110 and the cabinet door a to ensure a secure connection of the housing 110.
