Description

Technical Field

[0001] The invention belongs to the technical field of humidity monitoring, and in particular to a humidity monitoring and dehumidification system for a power distribution room. Background Art

[0002] A distribution room refers to an indoor distribution site with a low-voltage load. It mainly distributes electricity to low-voltage users and is equipped with medium-voltage incoming lines (a small number of outgoing lines may be available), distribution transformers and low-voltage distribution devices. Facilities with equipment of voltage levels of 10kV and below are divided into high-voltage distribution rooms and low-voltage distribution rooms. High-voltage distribution rooms generally refer to 6kV-10kV high-voltage switch rooms; low-voltage distribution rooms generally refer to 400V distribution with 10kV or 35kV station transformer outgoing lines. In order to ensure the normal operation of the distribution room, it is often necessary to monitor the humidity in the distribution room. The moisture in the distribution room is detected by a humidity monitor. When the humidity is too high, the moisture in the distribution room will be removed to achieve the purpose of intelligent monitoring and automatic dehumidification to ensure the normal operation of the distribution room.

[0003] At present, humidity monitors are often composed of a housing, a humidity sensor, and a control mainboard. The humidity sensor is often composed of a highly sensitive resistor element. The moisture in the air is detected by the resistor element, so that the resistance value of the resistor element changes and the current value changes. The humidity of the air is measured by the change in current. However, since the resistor element is often connected to the control mainboard through a wire, when the resistor element is damaged and needs to be replaced, people often need to remove the wire and replace it with a new wire connected with a resistor, and weld it to the mainboard. The steps are cumbersome. Therefore, a humidity monitoring and dehumidification system for a distribution room is proposed to solve the problems raised in the background technology. Summary of the invention

[0004] In order to solve the problems raised in the above background technology, the present invention provides a humidity monitoring and dehumidification system for a power distribution room, which solves the problem of complicated steps in the existing method when replacing sensor elements.

[0007] The block assembly is used to drive the movement of the round block. The block assembly limits the round block when it moves down to the middle of the housing.

[0008] The fixing component is movably connected to both sides of the connecting component. The connecting component is used to limit the horizontal position of the sensor body during the upward movement of the sensor body.

[0010] The connection component comprises:

[0011] A cover body is provided at the bottom of the first connecting line for fixing the first connecting line,

[0012] A bottom plate located on top of the sensor body for positioning it,

[0013] A first elastic block fixed to the bottom of the round block for supporting it,

[0014] A first pull rope fixedly connected to the top of the lower plate and passing upward through the cover body, wherein the first pull rope is used for the round block to drive the lower plate to rise.

[0018] The annular block is sleeved on the outside of the shell, and protrusions are arranged on both sides of the inner wall of the annular block. The protrusions pass through the inner wall of the shell inwardly and connect with the round block.

[0019] The card slots are evenly spaced on both sides of the shell.

[0020] The second elastic block and the third elastic block are connected via a second pull rope. When the second elastic block is pressed, the second pull rope drives the third elastic block to release the clamping connection with the clamping slot.

[0021] Preferably, both upper and lower ends of the annular block are connected to a corrugated protective sleeve sleeved on the outside of the housing, and the corrugated protective sleeve is used to prevent external dust from entering the interior of the housing.

[0022] Preferably, both sides of the cover body are convex, and one side of the lower plate is convex, and both convexities are circumferentially limited by a slide groove arranged inside the shell.

[0023] Preferably, a notch is provided on a side of the lower plate away from the protrusion, and is used to place the sensor body into the interior of the lower plate from a horizontal direction.

[0024] Preferably, a connector is fixedly connected to the top of the housing for connecting to an external power source.

[0025] The connector fixed to the top of the round block is used to cooperate with the connecting wire seat to supply power to the control mainboard.

[0026] When the round block moves downward, it drives the connector to move downward to release the connection with the connecting wire seat, and disconnects the power supply to the control mainboard.

[0027] Preferably, a first elastic block is provided on a side of the lower plate away from the notch.

[0028] A circular groove is provided on one side of the top of the sensor body for cooperating with the first elastic block for positioning.

[0030] Preferably, the fixing assembly comprises:

[0031] The arc blocks are set on both sides of the lower plate to limit the position of the sensor body.

[0032] The bent rod is fixed on one side of the arc block.

[0033] The spring rod is elastically connected to the inside of the lower plate to reset the arc block.

[0034] The limiting grooves are arranged on both sides of the inner wall of the shell and are used for limiting the position of the bending rod when it moves.

[0035] Preferably, the bending rod drives the arc block to retract into the interior of the lower plate when descending, so as to release the fixation of the sensor body.

[0036] A dehumidification system for a power distribution room, applied to a humidity monitoring device in the power distribution room,

[0037] S1. When the control module detects that the ambient humidity in the cabinet is higher than the set dehumidification threshold through the sensor body, it first controls the fan and heater to start working, heating the air in the cabinet to the preset temperature to gasify the condensation in the cabinet;

[0038] S2. Then the heater stops heating and turns on the condensing component to cool the water vapor in the electric cabinet and liquefy it and discharge it.

[0039] Compared with the prior art, the present invention has the following beneficial effects:

[0040] The present invention cooperates with the structures such as the card slot, the third elastic block, the connecting assembly and the round block, so that the device has the function of facilitating people to use the sensor element. By pressing the second elastic block, the third elastic block is pulled through the second pull rope to release the card slot, and then the annular block is moved downward to drive the first connecting line and the round block to move downward, thereby driving the cover body, the elastic corrugated sleeve and the lower plate to move downward. When the bottom of the protrusions on both sides of the cover body contacts the shell, the round block and the lower plate continue to move downward, which will relax the first pull rope. Under the elastic force of the elastic corrugated sleeve, the lower plate is squeezed to release the contact with the cover body and move to the bottom of the shell, so that it is convenient for operators to take out the sensor body and replace it.

[0041] The present invention improves the safety of people when replacing the sensor body through the cooperation between the connecting wire seat, the connecting head and the first connecting wire. When the first connecting wire is moved downward, the connecting wire seat is also driven to move downward, so that the connecting wire seat is separated from the cooperation with the connecting head during the downward process. At this time, the device is powered off, thereby improving the safety of the operator when replacing the sensor body.

[0042] The present invention cooperates between structures such as the arc block, the bending rod and the spring rod, so that the device has the function of releasing the fixation of the sensor body to facilitate people to replace the sensor body. During the downward movement of the lower plate, the bending rod will be driven to slide along the inside of the limiting groove, thereby driving the arc block to retract inward. When the bending rod moves down to the bottom of the shell, the spring rod can drive the arc block to remain in a state of being retracted inside the lower plate, thereby facilitating people to replace the sensor body later.

DETAILED DESCRIPTION

[0054] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0055] like Figures 1 to 10 As shown, the present invention provides a humidity monitoring device for a power distribution room, comprising a housing 1 and a control mainboard 8, the control mainboard 8 being used for data processing, a first connecting line 3 and a sensor body 5 arranged inside the housing 1 for transmitting data to the control mainboard 8, and further comprising:

[0056] The round block 2 and the connecting assembly 4 are arranged in the middle of the housing 1.

[0057] The block assembly 6 is used to drive the movement of the round block 2. When the block assembly 6 moves downward to the middle of the housing 1, it limits the round block 2.

[0058] The fixing component 11 is movably connected to both sides of the connecting component 4. The connecting component 4 is used to limit the horizontal position of the sensor body 5 during the upward movement of the sensor body 5.

[0059] A first connecting line 3 fixedly connected between the connecting component 4 and the round block 2 for driving the connecting component 4 downward,

[0060] The connection component 4 comprises,

[0061] A cover 401 is provided at the bottom of the first connecting line 3 for fixing the first connecting line 3.

[0062] A lower plate 403 located on the top of the sensor body 5 for positioning the sensor body,

[0063] A first elastic block 404 fixed to the bottom of the round block 2 for supporting it,

[0064] A first pull rope 406 is fixed to the top of the lower plate 403 and passes upward through the cover 401. The first pull rope 406 is used for the round block 2 to drive the lower plate 403 to rise.

[0065] The elastic corrugated sleeve 402 is connected between the lower plate 403 and the cover body 401; by pressing the second elastic block 602, the third elastic block 604 is pulled through the second pull rope 603 to release the clamping connection with the clamping slot 605, and then the annular block 601 is moved downward to drive the round block 2 and the first connecting line 3 to move downward, thereby driving the cover body 401, the elastic corrugated sleeve 402 and the lower plate 403 to move downward. When the raised bottoms on both sides of the cover body 401 contact the outer shell 1, the first connecting line 3 and the lower plate 403 continue to move downward, which will relax the first pull rope 406. Under the elastic force of the elastic corrugated sleeve 402, the lower plate 403 is squeezed to release the contact with the cover body 401 and move to the bottom of the outer shell 1, so as to facilitate the operator to take out the sensor body 5 and replace it.

[0066] like Figure 1 , Figure 2 , Figure 3 , Figure 5 , Figure 6 , Figure 7 and Fig.10 As shown, the block assembly 6 includes:

[0067] The second elastic block 602 and the third elastic block 604 are respectively and equidistantly arranged inside the round block 2.

[0068] The annular block 601 is sleeved on the outside of the housing 1, and protrusions are arranged on both sides of the inner wall of the annular block 601. The protrusions pass through the inner wall of the housing 1 inwardly and are connected to the round block 2.

[0069] The card slots 605 are equidistantly arranged on both sides of the housing 1.

[0070] The second elastic block 602 and the third elastic block 604 are connected by the second pull rope 603. When the second elastic block 602 is pressed, the second pull rope 603 drives the third elastic block 604 to release the clamping connection with the clamping slot 605. The upper and lower ends of the annular block 601 are connected to the corrugated protective sleeve 7 arranged on the outside of the shell 1, which is used to prevent external dust from entering the interior of the shell 1; through the clamping slot 605, when the round block 2 slides to the middle of the shell 1, the third elastic block 604 will be clamped into the clamping slot 605, thereby fixing the round block 2, thereby preventing the spring 405 from bouncing the round block 2, and also facilitating people to replace the sensor body 5 later.

[0071] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 , Figure 6 and Fig.10 As shown, both sides of the cover 401 are convex, and one side of the lower plate 403 is convex, both convexities are inside the housing 1, and are provided with sliding grooves that match them for circumferential limiting, and a notch is provided on the side of the lower plate 403 away from the convexity, which is used to put the sensor body 5 into the interior of the lower plate 403 from the horizontal direction; a connector 10 is fixedly connected to the top of the housing 1 for connecting an external power supply,

[0072] A connector 10 fixed to the top of the round block 2 is used to cooperate with the connecting wire seat 9 to supply power to the control mainboard 8.

[0073] When the round block 2 moves downward, it drives the connector 10 to move downward to release the connection with the connecting wire seat 9 and disconnect the power supply to the control mainboard 8; a first elastic block 404 is provided on one side of the lower plate 403 away from the notch.

[0074] A circular groove is provided on one side of the top of the sensor body 5 for cooperating with the first elastic block 404 for positioning.

[0075] Among them, after the sensor body 5 is placed into the lower plate 403, the first elastic block 404 is locked in the circular groove by rotating the sensor body 5; the cover body 401 and the lower plate 403 are designed to cooperate with the slide groove respectively, thereby playing a role in limiting the cover body 401 and the lower plate 403 when moving, thereby ensuring the accurate matching connection of the first connecting line 3 with the sensor body 5 in the subsequent process.

[0076] like Figure 4 , Figure 8 , Fig. 9 and Fig.10 As shown, the fixing assembly 11 includes:

[0077] The arc blocks 1101 are arranged on both sides of the lower plate 403 to fix the sensor body 5.

[0078] The bending rod 1102 is fixed to one side of the arc block 1101.

[0079] The spring rod 1103 is elastically connected to the inside of the lower plate 403 and is used to reset the arc block 1101.

[0080] The limiting groove 1104 is provided on both sides of the inner wall of the outer shell 1, and is used to limit the bending rod 1102 when it is downward. When the bending rod 1102 is downward, it drives the arc block 1101 to shrink to the inside of the lower plate 403, so as to release the fixation of the sensor body 5. In the process of the lower plate 403 moving downward, the bending rod 1102 will be driven to slide along the inside of the limiting groove 1104, thereby driving the arc block 1101 to shrink inward. When the bending rod 1102 moves down to the bottom of the outer shell 1, under the action of the spring rod 1103, the arc block 1101 can be driven to remain in the state of shrinking inside the lower plate 403, so as to facilitate people to replace the sensor body 5 later.

[0081] The working principle and use process of the present invention:

[0082] First, the operator presses the second elastic block 602 to pull the third elastic block 604 through the second pull rope 603 to release the clamping connection with the clamping slot 605, and then moves the annular block 601 downward to drive the round block 2 and the first connecting line 3 to move downward, thereby driving the cover body 401, the elastic corrugated sleeve 402 and the lower plate 403 to move downward. When the raised bottoms on both sides of the cover body 401 contact the housing 1, the first connecting line 3 and the lower plate 403 continue to move downward, which will relax the first pull rope 406. Under the elastic force of the elastic corrugated sleeve 402, the lower plate 403 is squeezed to release the contact with the cover body 401 and move to the bottom of the housing 1, so that the operator can take out the sensor body 5 and replace it.

[0083] When the lower plate 403 moves downward, the bending rod 1102 is driven to slide along the inner side of the limiting groove 1104, thereby driving the arc block 1101 to retract inward. When the bending rod 1102 moves downward to the bottom of the housing 1, the spring rod 1103 can drive the arc block 1101 to remain retracted inside the lower plate 403, thereby facilitating subsequent replacement of the sensor body 5.

[0084] When people move the round block 2 downward, the connecting wire seat 9 will also be driven to move downward, so that the connecting wire seat 9 will be separated from the connection head 10 during the downward process. At this time, the device is powered off, thereby improving the safety of the operator when replacing the sensor body 5.

[0085] It should be noted that, in this article, relational terms such as first and second, etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.

[0086] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
