Description

Technical Field

[0001] This invention relates to the field of hot water supply equipment technology, and in particular to a hot water supply system with power grid peak shaving function. Background Technology

[0002] A hot water supply system is a water supply system that ensures users can obtain hot water on time. A hot water supply system consists of hot water heating equipment, storage equipment, transmission pipelines, and control devices.

[0003] In existing hot water supply systems, as hot water usage increases, tap water needs to be continuously added to the storage equipment. Simultaneously, hot water heating equipment heats the water in the storage equipment. As tap water is continuously added and mixes with the hot water in the storage equipment, the water temperature in the storage equipment drops. During this time, the water heating rate is slow, affecting users' access to and use of hot water. Furthermore, during peak water usage periods, the operation of numerous hot water heating devices leads to increased electricity consumption, increasing the load on the power system and further impacting the operation of the hot water heating equipment.

[0004] Therefore, in view of this situation, it is necessary to develop a hot water supply system with grid peak-shaving function to meet the needs of actual use. Summary of the Invention

[0028] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0029] Example 1: A hot water supply system with grid peak-shaving function, see reference. Figures 1-3 and Figure 10As shown, the system includes a water tank 1, a control panel mounted on the front side of the water tank 1, support legs at the bottom of the water tank 1, and a first pipe 101 connected to the upper part of the water tank 1, penetrating and inserting into the water tank 1. A first circulation pump 102 connected to the first pipe 101 is mounted on the upper surface of the water tank 1. A second pipe 103 is connected to the upper side wall of the water tank 1, and a hot water utilization device is installed between the second pipe 103 and the first circulation pump 102. A liquid storage shell 104 is fixedly connected to the upper surface of the water tank 1 via a connecting block. The upper part is equipped with a liquid injection pipe, and the liquid storage shell 104 is located to the right of the first pipe 101. Both the side wall of the water tank 1 and the side wall of the liquid storage shell 104 are equipped with sealed chambers, and both sealed chambers are in a vacuum state to reduce heat loss. The lower part of the liquid storage shell 104 is connected to a third pipe 1041, which is inserted into the water tank 1 and fixed thereto. The third pipe 1041 is located to the right of the first pipe 101, and the lower end of the third pipe 1041 is near the lower end of the first pipe 101. An electrically controlled valve is installed on the third pipe 1041. The valve is located between the liquid storage shell 104 and the water tank 1. A first fixed shell 105 is fixed to the right side of the upper support leg of the water tank 1 via a connecting plate and bracket. An electric heating rod 1051 is fixed to the upper part of the first fixed shell 105, and the electric heating rod 1051 is located inside the first fixed shell 105. A rotating ring 1052 is rotatably and sealed at the lower part of the first fixed shell 105, and a second fixed shell 106 is rotatably and sealed at the lower part of the rotating ring 1052. A second circulation pump 108 is installed on the connecting plate of the water tank 1. The second circulation pump 108 is connected to the liquid storage shell 104. A fourth pipe 107 is connected between the second fixed shell 106 and the second circulation pump 108. A fifth pipe 109 is connected between the second fixed shell 105 and the liquid storage shell 104. A sixth pipe 110 is connected between the first fixed shell 105 and the liquid storage shell 104. The connection between the fourth pipe 107 and the liquid storage shell 104 is higher than the connection between the sixth pipe 110 and the liquid storage shell 104. The sixth pipe 110 is located at the lower part of the liquid storage shell 104. The electric control valve of the first circulation pump 102, the third pipe 1041, the electric heating rod 1051, and the second circulation pump 108 are all electrically connected to the control panel of the water tank 1.

[0030] The operator starts the second circulation pump 108 and the electric heating rod 1051 through the control panel of water tank 1 to circulate and heat the hot water. After the cold water fills the storage tank 104, the second circulation pump 108 works, so that the water in the upper part of the storage tank 104 is gradually injected into the second fixed tank 106 through the fourth pipe 107, the second circulation pump 108 and the fifth pipe 109 and accumulates there. Subsequently, the water fills the first fixed tank 105 and is injected into the lower part of the storage tank 104 through the sixth pipe 110. That is, the water circulates between the storage tank 104, the first fixed tank 105 and the second fixed tank 106. When the water in the circulation process passes through the first fixed tank 105 and the second fixed tank 106, the electric heating rod 1051 heats the water in the rising flow process.

[0031] Once the water is heated to a suitable temperature, the control panel opens the electric valve on the third pipe 1041, allowing hot water in the storage tank 104 to be slowly added to the water tank 1. Simultaneously, tap water is slowly injected into the storage tank 104. The injected water mixes with the hot water in the storage tank 104 and is quickly drawn away by the fourth pipe 107. The heated water is injected into the lower part of the storage tank 104 and enters the water tank 1 through the third pipe 1041. When the water tank 1 is full of hot water, the control panel closes the electric heating rod 1051, the second circulation pump 108, and the electric valve on the third pipe 1041, completing the hot water circulation heating operation. The storage tank 104 serves as an intermediate storage tank to prevent tap water from being directly injected into the water tank 1, which would cause the water temperature inside to drop, thus ensuring the supply and use of hot water.

[0032] Whenever the hot water utilization equipment uses hot water, the first circulation pump 102 operates to draw hot water stored in the water tank 1, and the hot water is transported to the hot water utilization equipment through the first pipe 101 and the first circulation pump 102. As the hot water is consumed, the control panel restarts the hot water circulation heating operation, so that hot water is injected into the lower part of the water tank 1, and the injected hot water is drawn away by the first pipe 101 for use.

[0033] During the use of hot water in the hot water utilization equipment, the control terminal stops starting the second circulation pump 108 and the electric heating rod 1051 during the midday peak electricity consumption period according to the set time. During the use of hot water, the control panel starts the first circulation pump 102 to continuously consume the hot water stored in the water tank 1. Since the side wall of the water tank 1 and the side wall of the liquid storage shell 104 are both equipped with sealed chambers, and both sealed chambers are in a vacuum state, the heat loss of the hot water stored in the water tank 1 and the liquid storage shell 104 is reduced, and the temperature of the hot water in the water tank 1 and the liquid storage shell 104 is guaranteed.

[0034] Meanwhile, based on the different electricity costs at different times, the operator makes corresponding settings on the control panel so that the hot water circulation heating system heats the tap water during periods of lower electricity costs and replenishes the heated hot water into water tank 1.

[0035] Example 2: Based on Example 1, refer to Figures 2-4As shown, it also includes a rotating mechanism, which is disposed on the first fixed shell 105. The rotating mechanism is used to rotate the rotating ring 1052. The rotating mechanism includes a drive motor 2 electrically connected to the control panel. The drive motor 2 is fixed to the left side wall of the first fixed shell 105 via a support. The output shaft of the drive motor 2 is equipped with a first spur gear 201. The rotating ring 1052 is equipped with a gear ring 202, which meshes with the first spur gear 201. A spiral plate 203 is fixed to the upper surface of the rotating ring 1052. Multiple third fixed shells 204 are fixed to the spiral plate 203 in an array along its spiral line. The upper side of the inner wall of the third fixed shell 204 is set as an inclined surface to guide the water flow to the electric heating rod 1051 at an inclined direction. Through the stirring of the spiral plate 203 and the third fixed shells 204, the water is uniformly heated by the electric heating rod 1051.

[0036] See Figures 3-6 As shown, it also includes a cleaning mechanism, which is disposed on the first fixed housing 105. The cleaning mechanism is used to clean the scale adhering to the electric heating rod 1051. The cleaning mechanism includes a rotating shaft 3, which is rotatably disposed on the right side of the first fixed housing 105 via a support block. A second spur gear 301 is fixedly connected to the lower end of the rotating shaft 3. The second spur gear 301 meshes with a gear ring 202. A reciprocating screw 302 is rotatably disposed on the upper surface of the first fixed housing 105 via a bracket. The reciprocating screw 302 and the rotating shaft 3 are driven by a sprocket and a chain. A sliding frame 303 that is threadedly engaged with the reciprocating screw 302 is slidably disposed on the first fixed housing 105. A first fixed frame 304 is fixedly connected to the lower end of the sliding frame 303. The lower part of the first fixed frame 304 is provided with an inclined surface. Two elastic telescopic rods 305 are fixedly connected to the first fixed frame 304. The upper ends of the two elastic telescopic rods 305 are fixedly connected to... A second fixed frame 306 is slidably fitted with the first fixed frame 304. A frustoconical filter screen is installed on the side wall of the second fixed frame 306. The frustoconical shape of the filter screen is used to guide the scale to move downward along its shape. A cleaning ring 307 is fixed to the upper part of the second fixed frame 306 through a connecting rod. The cleaning ring 307 is in contact with the electric heating rod 1051. The cross-section of the cleaning ring 307 is an isosceles triangle, and the cleaning ring 307 is provided with multiple cutting blades in a ring array to cut the scale on the electric heating rod 1051, making it easy for the cleaning ring 307 to scrape off the scale attached to the electric heating rod 1051. The second fixed frame 306 is provided with a centrifugal component for stirring the liquid. The electric heating rod 1051 is cleaned by the up-and-down reciprocating movement of the cleaning ring 307, ensuring that the contact area between the electric heating rod 1051 and the water remains unchanged, that is, ensuring that the heating efficiency of the electric heating rod 1051 on the water remains unchanged.

[0037] See Figure 5 and Figure 7As shown, the centrifugal assembly includes a rotating frame 4, which is located in the middle of the second fixed frame 306 and within the second fixed frame 306. The rotating frame 4 has three swing plates 401 arranged in a circular array. The rotating frame 4 is fixedly connected in a circular array to three sets of limiting posts 402, with two posts symmetrically distributed in each set. The swing plates 401 are located between the corresponding two limiting posts 402. The lower part of the rotating frame 4 is fixedly connected to a rotating frame 403 via a connecting rod. The rotating frame 403 consists of a ring and four inclined fan-shaped blades and is located at the lower part of the first fixed frame 304.

[0038] See Figure 3 , Figure 8 and Figure 9As shown, it also includes a collection mechanism, which is disposed in the second fixed shell 106. The inner wall of the second fixed shell 106 is frustoconical. The collection mechanism is used to collect scale after cleaning to ensure the water quality after heating. The collection mechanism includes a fourth fixed shell 5, which is fixed to the right side of the second fixed shell 106. The left side of the fourth fixed shell 5 is provided with a first through hole, and the lower part of the fourth fixed shell 5 is provided with a first round hole. The second fixed shell 106 is provided with a second through hole, which communicates with the first through hole of the fourth fixed shell 5. A rotating shell is rotatably disposed inside the fourth fixed shell 5. 501. The lower part of the rotating shell 501 is provided with an inclined surface to facilitate the flow of scale after settling into the second round hole of the rotating shell 501. The right side of the rotating shell 501 is provided with a third through hole, which mates with the first through hole of the fourth fixed shell 5. The lower part of the rotating shell 501 is provided with a second round hole, which mates with the first round hole of the fourth fixed shell 5. A third spur gear 502 is fixedly connected to the upper end of the rotating shell 501. A sliding rod 503 is provided in a limiting sliding manner on the upper part of the second fixed shell 106. The sliding rod 503 mates with the second fixed shell 106. A tension spring 504 is installed between 06. A rack is provided on the sliding rod 503, which meshes with the third spur gear 502. The sliding rod 503 has an inclined surface that engages with the second fixed frame 306. A third fixed frame 505 is fixedly connected to the lower side of the fourth fixed housing 5. The third fixed frame 505 has a third circular hole that communicates with the first circular hole of the fourth fixed housing 5. A fifth fixed housing 506 is sealed inside the third fixed frame 505. A fixing ring 507 is fixedly connected to the second fixed housing 106. Ring 507 is used to limit the second fixed frame 306. The rotating ring 1052 is arranged in a ring array with multiple inclined plates 508. As the second fixed frame 306 moves into the second fixed shell 106, the first fixed frame 304 gradually disengages from the second fixed frame 306, allowing the cleaned scale to enter the second fixed shell 106. Subsequently, under the centrifugal force of the water rotation caused by the rotation of the inclined plates 508, the scale adheres to the inner wall of the second fixed shell 106 and enters the rotating shell 501 after rotation, making it easier for the operator to remove the scale.

[0039] In the hot water circulation heating system, the control panel simultaneously starts the drive motor 2. The drive motor 2 drives the rotating ring 1052 to rotate counterclockwise through the first spur gear 201 and the gear ring 202. The rotating ring 1052 drives the spiral plate 203, all the third fixed shells 204 and all the inclined plates 508 to rotate together. The spiral plate 203 and all the third fixed shells 204 rotate and stir the water in the first fixed shell 105. The third fixed shell 204 guides the water in the first fixed shell 105 to move towards the electric heating rod 1051, so that the water in the first fixed shell 105 is heated evenly and the heating efficiency is improved. The inclined plates 508 rotate and stir the water in the second fixed shell 106, so that the water rotates in the first fixed shell 105 and the second fixed shell 106.

[0040] The gear ring 202 rotates simultaneously, causing the second spur gear 301 and the rotating shaft 3 to rotate. The rotating shaft 3 drives the reciprocating screw 302 to rotate continuously via a sprocket and chain. The rotation of the reciprocating screw 302 causes the sliding frame 303 to move up and down reciprocally. During the downward movement of the sliding frame 303, the sliding frame 303 drives the first fixed frame 304, the two elastic telescopic rods 305, and the second fixed frame 306 and other connected parts to move downward together. The second fixed frame 306 drives the cleaning ring 307 to move downward along the electric heating rod 1051 via a connecting rod. The cleaning ring 307 drives the cutting blade on it to move downward together. The downward movement of the cutting blade separates the scale attached to the side wall of the electric heating rod 1051, making it easier for the cleaning ring 307 to scrape off the scale attached to the side wall of the electric heating rod 1051, ensuring the contact area between the electric heating rod 1051 and the water inside the first fixed shell 105, and ensuring the heating efficiency of this device.

[0041] During the downward movement of the second fixed frame 306, the second fixed frame 306 drives the rotating frame 4, rotating frame 403 and other connected parts to move downward together. At this time, under the pulling force of the two elastic telescopic rods 305, the first fixed frame 304 continues to retract into the second fixed frame 306 and contacts its upper limit ring, and the lower surface of the first fixed frame 304 is parallel to the lower surface of the second fixed frame 306.

[0042] As the rotating frame 403 moves downward, water flows upward and impacts the rotating frame 403, causing the rotating frame 403 to drive the rotating frame 4 and the three swing plates 401 to rotate together. Under the resistance of the water, the rotating frame 4 causes the swing plates 401 to swing synchronously and contact the corresponding limiting posts 402. Subsequently, the rotation of the rotating frame 4 drives the three tilted swing plates 401 to rotate together and agitate the water in the first fixed shell 105. The scale that has been scraped off moves and accumulates at the filter screen of the second fixed frame 306 under centrifugal force. Since the filter screen of the second fixed frame 306 is frustoconical, and with the agitation of the three swing plates 401, the impurities move into the first fixed frame 304.

[0043] When the second fixed frame 306 moves into the second fixed shell 106, the second fixed frame 306 contacts the inclined surface of the pressing sliding rod 503, causing the sliding rod 503 to move to the right and stretch the tension spring 504. The rightward movement of the sliding rod 503 causes the rack on it to drive the third spur gear 502 and the rotating shell 501 to rotate. The rotation of the rotating shell 501 causes its third through hole to connect with the second through hole of the second fixed shell 106 through the first through hole of the fourth fixed shell 5. Then the second fixed frame 306 contacts the fixed ring 507, and the subsequent sliding frame 303 continues to move downward. The sliding frame 303 pushes the first fixed frame 304 to continue to move downward. The first fixed frame 304 disengages from the second fixed frame 306, and at the same time, the two elastic telescopic rods 305 are stretched and lengthened.

[0044] The first fixed frame 304 moves downward and gradually disengages from the second fixed frame 306, allowing the scale inside the first fixed frame 304 to enter the second fixed shell 106. Due to the rotation of the inclined plate 508, which agitates the water inside the second fixed shell 106, the scale adheres tightly to the inner wall of the second fixed shell 106 under centrifugal force. The cleaned scale then enters the rotating shell 501 through the third through hole, the first through hole, and the second through hole. Subsequently, the reciprocating screw 302 rotates, causing the sliding frame 303 to move upward. At this point, the reverse operation is performed, and the rotating shell 501 rotates in the opposite direction to reset. At this time, the second circular hole on the rotating shell 501... The first round hole of the fourth fixed shell 5 is engaged. At this time, water and scale are sealed inside the rotating shell 501. The water is still after being sealed, and the scale falls onto the inclined surface of the rotating shell 501. Then the scale enters the fifth fixed shell 506 through the second round hole, the first round hole and the third round hole. After working for a period of time, the operator opens the fifth fixed shell 506 and pulls it out during the upward movement of the sliding frame 303. This makes it easy for the operator to remove the cleaned scale from the liquid storage shell 104 and the second fixed shell 106, ensuring the circulation of water during the hot water addition process and the uniform and stable heating of the water by the electric heating rod 1051.

[0045] Although embodiments of the invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the appended claims and their equivalents.
