Description

Technical Field

[0001] The utility model relates to the technical field of distribution substations, in particular to an intelligent temperature management device for distribution substations. Background Technique

[0002] In modern society, people's life and work are inseparable from electricity, so higher requirements are put forward for the safety and stability of the power grid. The distribution substation is an important part of the power grid. The rationality of its design has a great impact on the improvement of power supply quality. At the same time, it is also an extremely common and very important work in engineering construction. Its standardization and technicality are very strong. It mainly focuses on the distribution, control and protection of power supply to users. There are many electrical equipment in the distribution substation, which will generate a lot of heat during operation. At this time, an intelligent temperature management device for distribution substations is needed.

[0003] When the existing intelligent temperature management device for distribution substations is in use, it usually uses a refrigeration system to assist in dissipating the heat in the distribution substation in time to keep the temperature in the distribution substation suitable and meet the operation requirements of electrical appliances. However, for small distribution substations in communities located outdoors, when the outdoor temperature is low, the refrigeration system is still activated for cooling, which is not conducive to the reasonable and effective use of energy. Content of the Utility Model

[0004] Based on this, the purpose of the utility model is to provide an intelligent temperature management device for distribution substations to solve the technical problem that the existing intelligent temperature management device for small distribution substations located outdoors separately activates the refrigeration system for cooling, which is not conducive to the reasonable and effective use of energy.

[0005] To achieve the above purpose, the utility model provides the following technical scheme: an intelligent temperature management device for distribution substations, including a distribution substation, a temperature and humidity meter, a viewing window and a circulating cold air blower. Natural heat dissipation mechanisms are arranged on both sides of the distribution substation. The natural heat dissipation mechanism includes a heat dissipation slot and a fixing frame. A screen is arranged at the heat dissipation slot. A storage box is arranged inside the fixing frame. Buckles are arranged on both sides of the storage box. Moisture-removing particles are arranged inside the storage box. Ventilation holes are opened on the storage box.

[0006] By adopting the above technical scheme, using the natural heat dissipation mechanism, when the outdoor temperature is relatively low, natural heat dissipation can be carried out, and heat exchange is carried out with the cold air outdoors. During heat exchange, impurities in the outside air are intercepted by the screen, and water vapor in the air is absorbed by the moisture-removing particles, so that the inside of the distribution substation remains clean, dry and at a suitable temperature. Only when the temperature measured by the temperature and humidity meter reaches the set value, the circulating cold air blower will start.

[0007] Furthermore, the storage box is fixedly connected with the buckle, the buckle is engaged with the fixing frame, two groups of buckles are provided, and the two groups of buckles are symmetrically arranged.

[0008] By adopting the above technical solution, the fixed frame is provided, and the storage box can be fixed at the inner position of the heat dissipation groove through the buckle, so that the air filtered by the screen at the heat dissipation groove can enter the interior of the storage box through the ventilation holes after passing through the heat dissipation groove.

[0009] Further, two groups of ventilation holes are provided. One group of ventilation holes is provided on the side of the storage box close to the screen, and the other group of ventilation holes is provided on the side of the storage box far from the screen.

[0010] By adopting the above technical solution, the position of the ventilation holes enables the two groups of ventilation holes to penetrate the storage box, so that the outside air can contact the moisture-removing particles through the ventilation holes penetrating the storage box.

[0011] Further, the moisture-removing particles are made of inorganic silica gel, and the diameter of the moisture-removing particles is larger than the aperture of the ventilation holes.

[0012] By adopting the above technical solution, the moisture-removing particles are made of inorganic silica gel, and the water vapor in the air entering the substation can be smoothly adsorbed by using the micropores of the inorganic silica gel. The moisture-removing particles made of inorganic silica gel after water absorption saturation can be regenerated by means such as exposure to the sun, baking, and air drying, and the regenerated moisture-removing particles can be reused.

[0013] Further, the storage box is a rectangular structure with an open top, and the storage box is made of a transparent material.

[0014] By adopting the above technical solution, the top of the storage box is open, which facilitates taking out the moisture-removing particles from the top of the storage box when the moisture-removing particles are saturated with water and need to be replaced.

[0015] Further, the thermometer and the circulating cooling fan are connected through an external controller.

[0016] By adopting the above technical solution, when the temperature value measured by the thermometer reaches the set value, the external controller controls the circulating cooling fan to start, and before the temperature continues to rise to a dangerous state, the circulating cooling fan is used to forcibly cool the interior of the substation.

[0017] Further, a pull ring is provided on the buckle, a sloping plate is provided on the outside of the storage box, a moving plate is provided at the bottom of the storage box, sliding rods are provided on both sides of the storage box, a pull rod and a second buffer block are provided in the middle of the top of the moving plate, first buffer blocks are provided on both sides of the top of the moving plate, and a rain shield is provided on the top of the heat dissipation groove.

[0018] By adopting the above technical solution, the moving plate can assist the staff in taking out and replacing the moisture-removing particles in the storage box to ensure the continuous progress of the moisture-removing operation, and the pull rod is provided to facilitate the staff to pull the moving plate upward.

[0019] Further, the pull rod is fixedly connected to the moving plate, and the length of the pull rod is greater than the depth of the storage box.

[0020] By adopting the above technical solution, when the staff pulls the pull rod, the moving plate fixedly connected thereto is driven to move upward, and then the dehumidifying particles are pushed to move upward.

[0021] Further, the moving plate abuts against the bottom of the storage box, the sliding rod is fixedly connected to the storage box, and the moving plate is slidably connected to the sliding rod.

[0022] By adopting the above technical solution, when the moving plate moves upward driven by the pull rod, it smoothly slides along the sliding rod on both sides.

[0023] Further, the first buffer block is arranged to be inclined on one side, the second buffer block is arranged to be inclined on both sides, and both the first buffer block and the second buffer block are fixedly connected to the moving plate.

[0024] By adopting the above technical solution, the first buffer block and the second buffer block are arranged to conveniently use the slopes on one side or both sides thereof to divert the dehumidifying particles to a position far from the sliding rod and the pull rod.

[0025] In summary, the present utility model mainly has the following beneficial effects:

[0026] 1. By setting a thermometer and hygrometer, heat dissipation grooves, a screen, a storage box and dehumidifying particles, when the outdoor temperature is relatively low, such as after rain or in a cold winter, when natural heat exchange can meet the heat dissipation requirements of the electrical appliances inside the substation, the inside and outside of the substation can be connected through the heat dissipation grooves and ventilation holes for natural cooling. The screen is used to intercept impurities in the air, and the dehumidifying particles are used for dehumidification inside the substation to ensure that the air inside the substation is as clean and dry as possible. When the thermometer and hygrometer detect that the temperature is too high, the controller controls the circulating cooling fan to start for forced cooling. The circulating cooling fan only needs to be started when needed, saving energy to a certain extent.

[0027] 2. By setting a moving plate, a sliding rod, a pull rod and an inclined plate, when the dehumidifying particles absorb enough moisture and the humidity value measured by the thermometer and hygrometer begins to rise, at this time, the staff pulls the pull rod to drive the dehumidifying particles to move upward. The dehumidifying particles overflowing from the storage box slide down along the inclined plate, are smoothly collected, and new dehumidifying particles are replaced for continuous use. The taken-out saturated dehumidifying particles can be reused after regeneration treatment. BRIEF DESCRIPTION OF THE DRAWINGS

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present utility model and should not be construed as limiting the present utility model.

[0036] Next, the embodiments of the present utility model will be described according to its overall structure.

[0037] Embodiment 1:

[0038] An intelligent temperature management device for a substation, as Figures 1-6As shown in the figure, it includes a distribution substation 1, a temperature and humidity meter 2, a visual window 3, and a circulating cooling fan 4. Natural heat dissipation mechanisms 5 are provided on both sides of the distribution substation 1. The natural heat dissipation mechanism 5 includes a heat dissipation slot 501 and a fixing frame 503. A screen 502 is provided at the heat dissipation slot 501. An object placement box 505 is provided inside the fixing frame 503. Clasps 504 are provided on both sides of the object placement box 505. Moisture-removing particles 506 are provided inside the object placement box 505. Ventilation holes 507 are opened on the object placement box 505. By using the natural heat dissipation mechanism 5, when the outdoor temperature is relatively low, natural heat dissipation can be carried out, and heat exchange is performed with the cold air outdoors. When heat exchanging, impurities in the external air are intercepted by the screen 502, and water vapor in the air is absorbed by the moisture-removing particles 506, so that the inside of the distribution substation 1 is kept clean, dry, and at a suitable temperature. Only when the temperature measured by the temperature and humidity meter 2 reaches the set value, the circulating cooling fan 4 will start to effectively dissipate heat inside the distribution substation 1. In this way, reasonable and effective utilization of energy can be ensured. In reality, to save energy, the start or stop of the circulating cooling fan 4 is often controlled manually. However, manual control is limited by the time of personnel inspection. Even if the inspection frequency is increased, the circulating cooling fan 4 cannot be turned on instantly when the value of the temperature and humidity meter 2 reaches the predetermined value, and the flexibility is poor.

[0039] Refer to Figure 3 、 Figure 4 、 Figure 5 , the object placement box 505 is fixedly connected to the clasp 504, and the clasp 504 is engaged with the fixing frame 503. Two groups of clasps 504 are provided, and the two groups of clasps 504 are symmetrically arranged. The setting of the fixing frame 503 can fix the object placement box 505 at the inner position of the heat dissipation slot 501 through the clasp 504, so that the air filtered by the screen 502 at the heat dissipation slot 501 can enter the inside of the object placement box 505 through the ventilation holes 507 after passing through the heat dissipation slot 501 and be dehumidified by the moisture-removing particles 506. The two symmetrically arranged groups of clasps 504 firmly fix the object placement box 505 on the fixing frame 503 from both sides, ensuring the fixing effect.

[0040] Refer to Figure 3 、 Figure 4 , two groups of ventilation holes 507 are opened. One group of ventilation holes 507 is opened on the side of the object placement box 505 close to the screen 502, and the other group of ventilation holes 507 is opened on the side of the object placement box 505 far from the screen 502. The setting position of the ventilation holes 507 enables the two groups of ventilation holes 507 to penetrate the object placement box 505. Thus, the external air can pass through the ventilation holes 507 that penetrate the object placement box 505 and contact the moisture-removing particles 506 for dehumidification operations. Each group of heat dissipation slots 501 corresponds to a group of ventilation holes 507, and each group of ventilation holes 507 is evenly and equidistantly provided with a plurality of them, facilitating the air entering from the heat dissipation slot 501 to contact the nearest moisture-removing particles 506 as soon as possible.

[0041] Refer toFigure 3 , Figure 4 , Figure 5 , Figure 6 , the moisture-removing particles 506 are made of inorganic silica gel. The diameter of the moisture-removing particles 506 is larger than the aperture of the ventilation holes 507. The moisture-removing particles 506 are made of inorganic silica gel, and the fine pores of the inorganic silica gel can be used to smoothly adsorb the water vapor in the air entering the substation 1. The moisture-removing particles 506 made of inorganic silica gel after being saturated with water can be regenerated by means such as sun exposure, baking, and air drying. The regenerated moisture-removing particles 506 can be reused. The relatively large diameter of the moisture-removing particles 506 prevents the moisture-removing particles 506 from leaking out through the ventilation holes 507, causing the loss of the moisture-removing particles 506.

[0042] Refer to Figure 3 , Figure 4 , the storage box 505 is a rectangular structure with an open top. The storage box 505 is made of a transparent material. The open top of the storage box 505 facilitates the removal of the moisture-removing particles 506 from the top of the storage box 505 when the moisture-removing particles 506 are saturated with water and need to be replaced. The selection of the transparent material for the storage box 505 makes it convenient to confirm that all the moisture-removing particles 506 have been removed when taking out the moisture-removing particles 506 from the storage box 505.

[0043] Refer to Figure 2 , Figure 3 , Figure 4 , the thermometer-hygrometer 2 and the circulating cooling fan 4 are connected by an external controller. When the temperature value measured by the thermometer-hygrometer 2 reaches the set value, the external controller controls the circulating cooling fan 4 to start, and before the temperature continues to rise to a dangerous state, the circulating cooling fan 4 is used to forcibly cool the interior of the substation 1. Controlled by the controller, the response of the circulating cooling fan 4 can be made more accurate and better adapted to the temperature value measured by the thermometer-hygrometer 2.

[0044] Embodiment 2:

[0045] Refer to Figure 3 , Figure 4 , Figure 5 , Figure 6 , a pull ring 10 is provided on the buckle 504, a sloping plate 9 is provided on the outside of the storage box 505, a moving plate 6 is provided at the bottom of the storage box 505, sliding rods 7 are provided on both sides of the storage box 505, a pull rod 8 and a second buffer block 12 are provided in the middle of the top of the moving plate 6, first buffer blocks 11 are provided on both sides of the top of the moving plate 6, and a rain shield 13 is provided at the top of the heat dissipation slot 501. The setting of the moving plate 6 can assist the staff in taking out the moisture-removing particles 506 in the storage box 505 for replacement, ensuring the continuous progress of the moisture-removing operation. The setting of the pull rod 8 facilitates the staff to pull the moving plate 6 upward to take out the moisture-removing particles 506. The setting of the rain shield 13 can play a role in blocking rain at the heat dissipation slot 501, intercepting the rain outside the heat dissipation slot 501.

[0046] Refer to Figure 3 、 Figure 4 、 Figure 6 The pull rod 8 is fixedly connected to the moving plate 6. The length of the pull rod 8 is greater than the depth of the storage box 505. When the staff pulls the pull rod 8, the moving plate 6 fixedly connected thereto is driven to move upward, thereby pushing the dehumidifying particles 506 upward. The length of the pull rod 8 is relatively long and extends outside the storage box 505, facilitating the staff to apply force to the pull rod 8 with their hands.

[0047] Refer to Figure 4 、 Figure 5 The moving plate 6 abuts against the bottom of the storage box 505. The sliding rod 7 is fixedly connected to the storage box 505. The moving plate 6 is slidably connected to the sliding rod 7. When the moving plate 6 is driven by the pull rod 8 to move upward, it smoothly slides along the sliding rod 7 on both sides, using the sliding rod 7 to assist the upward movement of the moving plate 6 to ensure that its up and down movement is smoother.

[0048] Refer to Figure 4 、 Figure 5 、 Figure 6 The first buffer block 11 is arranged with a single-sided inclination, and the second buffer block 12 is arranged with a double-sided inclination. Both the first buffer block 11 and the second buffer block 12 are fixedly connected to the moving plate 6. The settings of the first buffer block 11 and the second buffer block 12 facilitate using the single-sided or double-sided slopes thereof to divert the dehumidifying particles 506 to a position away from the sliding rod 7 and the pull rod 8, preventing the dehumidifying particles 506 at the bottom from being clamped in the gaps between the sliding rod 7 or the pull rod 8 and the storage box 505 after the moving plate 6 rises to the limit, ensuring that the replacement process of the dehumidifying particles 506 is smoother.

[0049] The implementation principle of the present utility model is as follows: When the external environmental temperature is relatively low, heat dissipation is carried out through the natural heat dissipation mechanism 5. The air inside the power distribution station 1 exchanges heat with the external cold air at the heat dissipation slots 501. When the external air reaches the heat dissipation slots 501, impurities in the air are intercepted by the screen 502. The clean air that passes through passes through the ventilation holes 507 on one side of the storage box 505 and contacts the moisture removal particles 506. The moisture in the air is adsorbed by the moisture removal particles 506, and the external cold air enters the power distribution station 1 to cool it down. When the temperature inside the power distribution station 1 measured by the temperature and humidity meter 2 rises and is higher than the set value, this signal is transmitted to the external controller, and the external controller controls the circulation cooling fan 4 to start to forcibly cool the inside of the power distribution station 1. When the inspection staff judges that the moisture removal particles 506 are saturated based on the humidity value on the temperature and humidity meter 2, they pull the top of the pull rod 8, driving the moving plate 6 to slide upward along the sliding rod 7, causing the moisture removal particles 506 to move upward passively and overflow from the open mouth of the storage box 505 and roll down along the inclined plate 9 to be collected. Due to the guiding effect of the first buffer block 11 and the second buffer block 12, it is difficult for the moisture removal particles 506 at the bottom layer to hide near the sliding rod 7 and the pull rod 8, and they can also be successfully collected. After taking out the saturated moisture removal particles 506, the pull rod 8 is pushed down to move the moving plate 6 downward to reset, and new moisture removal particles 506 are replenished. The saturated moisture removal particles 506 are regenerated and properly stored for continued use next time.

[0050] Parts not involved in the present utility model are the same as or can be implemented using the prior art, and will not be elaborated here.

[0051] Although the embodiments of the present utility model have been shown and described, the specific embodiments are only explanations of the present utility model and not limitations thereof. The specific features, structures, materials or characteristics described can be combined in a suitable manner in any one or more embodiments or examples. After reading this specification, those skilled in the art can, without departing from the principles and purposes of the present utility model, make modifications, substitutions and variations that do not contribute creatively to the embodiments as needed, but as long as they are within the scope of the claims of the present utility model, they are protected by the patent law.
