Description

Technical Field

[0001] The invention relates to the technical field of combined heat and power generation, and in particular to a high-stability electric heating component for solar combined heat and power generation. Background Art

[0002] Combined heat and power technology is a new generation of residential power and heating solutions. It can reasonably allocate electricity according to users' heat needs, intercept photovoltaic electricity as needed to supplement solar thermal power, thereby greatly improving the flexibility of heating and environmental adaptability.

[0003] However, as the usage time increases, the performance of the heating part (including: reduced heating speed, increased power consumption) will decline to a certain extent. Even if the scale on the electric heating components is cleaned on time, the problem of reduced heating performance often occurs.

[0004] In view of this, this application is hereby filed. Summary of the invention

[0005] The purpose of the present invention is to provide a high-stability electric heating component for solar heat and power cogeneration, which can further troubleshoot the problem of reduced heating performance and improve the continuous stability of heating. At the same time, it can also evaluate the heating safety and component health, thereby improving the overall efficiency of heating.

[0006] The embodiment of the present invention is achieved as follows:

[0007] A high-stability electric heating component for solar thermal power cogeneration comprises a mounting seat, an electric heating mechanism, a heat-conducting sleeve, a cleaning ring and a driving mechanism.

[0008] The electric heating mechanism is installed on the mounting seat, the electric heating mechanism is arranged horizontally, the heat-conducting sleeve is arranged on the electric heating mechanism and connected to the mounting seat. The inner wall of the heat-conducting sleeve has an internal thread, and the internal thread of the heat-conducting sleeve extends to both ends of the heat-conducting sleeve.

[0009] The cleaning ring comprises a ring body, a sealing cover and an abutment block.

[0010] The inner diameter of the ring body is larger than the outer diameter of the electric heating mechanism, and the outer diameter of the ring body is smaller than the inner diameter of the heat-conducting sleeve. The ring body is arranged around the electric heating mechanism and accommodated in the heat-conducting sleeve.

[0011] The ring body is a hollow structure, and the outer ring wall of the ring body is provided with slag inlets communicated with the inner space thereof, and there are at least two slag inlets which are evenly spaced along the circumference of the ring body.

[0012] Each slag inlet is equipped with a sealing cover and an abutment block.

[0013] The sealing cover is arranged inside the ring body, one side edge of the sealing cover is hinged to one side edge of the slag inlet, and a counterweight is connected to one side of the sealing cover away from the slag inlet.

[0014] The abutment block is wedge-shaped and is arranged on the outer ring wall of the ring body and near the edge of the slag inlet. One corner of the abutment block is hinged to one side edge of the slag inlet, and an elastic member is abutted between the side wall of the abutment block close to the ring body and the outer ring wall of the ring body, so that the corner of the abutment block away from its hinged end fits the inner wall of the heat-conducting sleeve. The side wall of the abutment block away from the ring body is a guide wall, and the guide wall is smoothed. The corner of the abutment block away from its hinged end has a toothed portion for matching with the internal thread of the heat-conducting sleeve.

[0015] The driving mechanism is used to drive the cleaning ring to rotate relative to the heat-conducting sleeve, so that the cleaning ring moves along the axial direction of the heat-conducting sleeve, so that the abutment block can clean the inner wall of the heat-conducting sleeve. When the slag inlet moves to the upper half of the ring body, the corresponding cover rotates toward the inside of the ring body under the gravity of the counterweight and opens. When the slag inlet moves to the lower half of the ring body, the corresponding cover rotates toward the outside of the ring body under the gravity of the counterweight and closes the slag inlet.

[0016] Furthermore, the guide wall is provided with a guide groove, which extends along the surface of the guide wall, is spaced apart from the tooth portion, penetrates to a side wall of the abutment block away from the mounting seat, and extends to a side edge of the guide wall close to the slag inlet.

[0017] Furthermore, the mounting seat includes: a positioning column, a rotating ring, a positioning cylinder, a seat body, a rotating shaft and a rear cover.

[0018] The rotating ring is sleeved and fixedly connected to the positioning column, and the rotating ring and the positioning column are coaxially arranged. The electric heating mechanism is installed on the positioning column and extends along the axial direction of the positioning column.

[0019] The positioning tube is sleeved on the rotating ring, and the rotating ring is rotatably matched with the positioning tube. The heat-conducting sleeve and the positioning tube are coaxially arranged and fixedly connected. The inner diameter of the positioning tube is equal to the inner diameter of the heat-conducting sleeve, and the positioning tube also has an internal thread, and the internal thread of the positioning tube is continuous with the internal thread of the heat-conducting sleeve.

[0020] The seat body has an installation cavity, the positioning cylinder extends to the installation cavity and is fixedly connected to the seat body, and the mouth of the installation cavity is closed by a blocking member. A matching hole is opened at the bottom of the seat body, the matching hole is coaxially arranged with the positioning cylinder, and the rotating shaft can be rotatably matched with the matching hole.

[0021] The rotating shaft has an axial through hole, and the wire of the electric heating mechanism is led out through the axial through hole. The rear cover is arranged on the side of the seat body away from the positioning cylinder, and the rotating shaft is located inside the rear cover. The driving mechanism is arranged inside the rear cover and cooperates with the rotating shaft in transmission.

[0022] The rotating shaft is fixedly connected with a driving rod, which is extended along the axial direction of the positioning cylinder. The driving rod sequentially penetrates the rotating ring and the ring body and extends to the end of the heat-conducting sleeve away from the mounting seat. Along the axial direction of the driving rod, the driving rod is slidably matched with the ring body. Along the circumferential direction of the driving rod, the driving rod is rotationally matched with the ring body.

[0023] Furthermore, the driving mechanism is provided with a control module and a detection module for detecting driving resistance. The detection module is electrically connected to the control module.

[0024] The control module stores the lower limit value and the upper limit value of the driving resistance. When the driving resistance detected by the detection module is less than the lower limit value of the driving resistance, or the driving resistance detected by the detection module is greater than the upper limit value of the driving resistance, the control module issues a prompt and controls the driving mechanism to stop working.

[0025] The beneficial effects of the technical solution of the embodiment of the present invention include:

[0026] During the use of the high-stability electric heating assembly for solar heat and power cogeneration provided by the embodiment of the present invention, since the cleaning ring realizes threaded cooperation with the heat-conducting sleeve through the abutment block, when the driving mechanism drives the cleaning ring to rotate relative to the heat-conducting sleeve, the cleaning ring can move along the axial direction of the heat-conducting sleeve. In other words, when the cleaning ring rotates, the abutment block can be used to clean the inner wall of the heat-conducting sleeve, and at the same time, the cleaning ring can also move along the circumference of the heat-conducting sleeve, thereby completing the cleaning of the "debris" on the entire inner wall of the heat-conducting sleeve.

[0027] Based on this, when the cleaning ring rotates, the abutment block can clean up the "debris" on the inner wall of the heat-conducting sleeve, and part of the cleaned "debris" can fall into the guide groove located in the upper half of the ring body, and then be smoothly introduced into the slag inlet (in the open state) located in the upper half of the ring body. Due to the existence of the guide groove, the cleaned "debris" can be prevented from falling to the side of the cleaning ring close to the mounting seat.

[0028] Another part of the "debris" may fall directly to the bottom of the inner wall of the heat-conducting sleeve during the cleaning process. For this part of the "debris", the abutment block can collect it during the circumferential movement. Due to the existence of the guide groove, the "debris" can be confined within the range of the guide groove and move with the abutment block. When the corresponding abutment block moves toward the upper half of the ring body and finally moves to the upper half, the "debris" carried by the guide groove can fall into the guide groove smoothly, and finally fall into the slag inlet along the guide groove. In this way, the collection of the "debris" can be completed.

[0029] In general, the high-stability electric heating components for solar cogeneration provided by the embodiments of the present invention can further troubleshoot the problem of reduced heating performance and improve the continuous stability of heating. At the same time, it can also evaluate the heating safety and the health of components, thereby improving the overall efficiency of heating. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0039] In order to make the purpose, technical solutions and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Generally, the components of the embodiments of the present invention described and shown in the drawings here can be arranged and designed in various different configurations.

[0040] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention claimed for protection, but merely represents selected embodiments of the present invention. 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.

[0041] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, further definition and explanation thereof is not required in subsequent drawings.

[0042] In addition, the terms "parallel", "vertical", etc. do not mean that the components must be absolutely parallel or vertical, but can be slightly tilted. For example, "parallel" only means that its direction is more parallel than "vertical", and does not mean that the structure must be completely parallel, but can be slightly tilted.

[0043] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "setting", "installation" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be a communication between the two elements. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0044] During the use of the electric heating component, even if the scale on the surface is cleaned on time, its electric heating effect is likely to decrease significantly as the use time increases. The inventors of the present application have found that in addition to the influence of equipment aging, the inner wall of the thermal sleeve 300 of the electric heating component will also have a significant impact on the electric heating effect. During use, the thermal sleeve 300 repeatedly undergoes heating and cooling processes, and the working temperature of the thermal sleeve 300 often switches between high temperature and normal temperature. For some types of thermal sleeves 300, as the use time increases, "debris" may be generated on its inner wall. The presence of these "debris" will affect the heat transfer effect of the thermal sleeve 300 to a certain extent, thereby causing a decrease in the electric heating effect. In actual use, when a certain amount of "debris" is generated, the service life of the thermal sleeve is actually relatively long. If it is directly replaced, it will lead to an increase in maintenance costs and cause unnecessary waste. However, there is no method in the prior art that can easily clean these "debris".

[0045] The technical solution of this application can effectively solve these technical problems. For details, please refer to Figure 1 to Figure 6 This embodiment provides a high-stability electric heating component for solar thermal power cogeneration, and the high-stability electric heating component includes: a mounting seat 100, an electric heating mechanism 200, a heat-conducting sleeve 300, a cleaning ring 400 and a driving mechanism 500.

[0046] The electric heating mechanism 200 is installed on the mounting seat 100. The electric heating mechanism 200 is arranged horizontally. The heat-conducting sleeve 300 is extended along the length direction of the electric heating mechanism 200. The heat-conducting sleeve 300 is covered on the electric heating mechanism 200 and connected to the mounting seat 100. The heat-conducting mechanism and the mounting seat 100 are sealed, so that the electric heating mechanism 200 is enclosed in the heat-conducting sleeve 300.

[0047] The inner wall of the heat-conducting sleeve 300 has an internal thread, and the internal thread of the heat-conducting sleeve 300 extends from an end close to the mounting seat 100 to an end away from the mounting seat 100 .

[0048] In this embodiment, the mounting base 100 includes a positioning column 110 , a rotating ring 120 , a positioning cylinder 130 , a base body 140 , a rotating shaft 160 and a rear cover 170 .

[0049] The rotating ring 120 is sleeved and fixedly connected to the positioning column 110, and the rotating ring 120 is coaxially arranged with the positioning column 110. The electric heating mechanism 200 is installed on the positioning column 110 and extends along the axial direction of the positioning column 110. The wire of the electric heating mechanism 200 passes through the inside of the positioning column 110 and comes out from the end of the positioning column 110 away from the electric heating mechanism 200. The rotating ring 120 is located at the end of the positioning column 110 away from the electric heating mechanism 200.

[0050] The positioning tube 130 is sleeved on the rotating ring 120, and the rotating ring 120 is rotatably matched with the positioning tube 130. The heat-conducting sleeve 300 and the positioning tube 130 are coaxially arranged, and the end surfaces of the heat-conducting sleeve 300 and the positioning tube 130 are abutted and fixedly connected.

[0051] The inner diameter of the positioning tube 130 is equal to the inner diameter of the thermal sleeve 300 , and the positioning tube 130 also has an internal thread, which is continuous with the internal thread of the thermal sleeve 300 , that is, the internal thread of the positioning tube 130 and the internal thread of the thermal sleeve 300 can together form a longer, continuous internal thread.

[0052] The seat body 140 has an installation cavity, the positioning cylinder 130 extends to the installation cavity and is fixedly connected to the seat body 140, and the mouth of the installation cavity is closed by the blocking member 150. The bottom of the seat body 140 is provided with a matching hole, which is coaxially arranged with the positioning cylinder 130, and the rotating shaft 160 is rotatably matched with the matching hole.

[0053] The rotating shaft 160 has an axial through hole 161, and the wire of the electric heating mechanism 200 is led out through the axial through hole 161. The rear cover 170 is disposed on the side of the seat body 140 away from the positioning cylinder 130, and the rotating shaft 160 is located inside the rear cover 170. The driving mechanism 500 is disposed inside the rear cover 170 and is in transmission cooperation with the rotating shaft 160 to drive the rotating shaft 160.

[0054] The cleaning ring 400 includes a ring body 410 , a cover 420 , and an abutment block 430 .

[0055] The inner diameter of the ring body 410 is larger than the outer diameter of the electric heating mechanism 200, and the outer diameter of the ring body 410 is smaller than the inner diameter of the heat-conducting sleeve 300. The ring body 410 is disposed around the electric heating mechanism 200 and accommodated in the heat-conducting sleeve 300. A gap is left between the inner ring wall of the ring body 410 and the electric heating mechanism 200, and a gap is also left between the outer ring wall of the ring body 410 and the heat-conducting sleeve 300.

[0056] The ring body 410 is a hollow structure. The outer ring wall of the ring body 410 is provided with slag inlets 411 connected to its internal space. There are at least two slag inlets 411 (six in this embodiment, but not limited thereto). The slag inlets 411 are evenly spaced along the circumference of the ring body 410 .

[0057] Each slag inlet 411 is equipped with a sealing cover 420 and an abutment block 430 .

[0058] The cover 420 is arranged inside the ring body 410 , and one side edge of the cover 420 is hinged to one side edge of the slag inlet 411 . A counterweight 421 is connected to the side of the cover 420 away from the slag inlet 411 , and the counterweight 421 is arranged away from the hinge axis of the cover 420 .

[0059] The abutment block 430 is wedge-shaped and is disposed on the outer ring wall of the ring body 410 and close to the edge of the slag inlet 411. One corner of the abutment block 430 is hinged to one side edge of the slag inlet 411, and an elastic member 440 is abutted between a side wall of the abutment block 430 close to the ring body 410 and the outer ring wall of the ring body 410, so that a corner of the abutment block 430 away from its hinged end is attached to the inner wall of the heat-conducting sleeve 300.

[0060] The side wall of the abutment block 430 away from the ring body 410 is a guide wall 431, which is smoothed. One end of the guide wall 431 extends to the edge of the slag inlet 411, and the other end extends to the inner wall of the heat-conducting sleeve 300. A corner of the abutment block 430 away from its hinged end (i.e., a corner corresponding to the end of the guide wall 431 away from the slag inlet 411) has a toothed portion 432 for matching with the internal thread of the heat-conducting sleeve 300.

[0061] The rotating shaft 160 is fixedly connected with a driving rod 162, which is extended along the axial direction of the positioning cylinder 130. The driving rod 162 sequentially penetrates the rotating ring 120 and the ring body 410 and extends to the end of the heat-conducting sleeve 300 away from the mounting seat 100. Along the axial direction of the driving rod 162, the driving rod 162 and the ring body 410 are slidably matched. Along the circumferential direction of the driving rod 162, the driving rod 162 is rotationally matched with the ring body 410. The driving rod 162 is spaced apart from the inner wall of the heat-conducting sleeve 300, and the driving rod 162 and the electric heating mechanism 200 are also spaced apart. A stopper 163 for preventing the ring body 410 from slipping out is provided at the end of the driving rod 162 away from the rotating shaft 160.

[0062] In this embodiment, there are two driving rods 162 .

[0063] When the driving mechanism 500 drives the rotating shaft 160 , the rotating shaft 160 drives the driving rod 162 to move. When the driving rod 162 moves, the rotating ring 120 and the ring body 410 rotate synchronously, thereby realizing the driving mechanism 500 driving the cleaning ring 400 .

[0064] Since the cleaning ring 400 is threadedly matched with the heat-conducting sleeve 300 through the abutment block 430, when the driving mechanism 500 drives the cleaning ring 400 to rotate relative to the heat-conducting sleeve 300, the cleaning ring 400 can move along the axial direction of the heat-conducting sleeve 300. In other words, when the cleaning ring 400 rotates, the abutment block 430 can be used to clean the inner wall of the heat-conducting sleeve 300, and the cleaning ring 400 can also move along the circumference of the heat-conducting sleeve 300, thereby completing the cleaning of the "debris" on the entire inner wall of the heat-conducting sleeve 300.

[0065] In this embodiment, a guide groove 433 is formed on the guide wall 431 of the abutment block 430, and the guide groove 433 extends along the surface of the guide wall 431, and the guide groove 433 and the tooth portion 432 are spaced apart (i.e., a gap is left between the guide groove 433 and the tooth portion 432), and the guide groove 433 and a side edge of the guide wall 431 close to the mounting seat 100 are spaced apart (i.e., a gap is left between the guide groove 433 and a side edge of the guide wall 431 close to the mounting seat 100), and the guide groove 433 penetrates to a side wall of the abutment block 430 away from the mounting seat 100, and extends to a side edge of the guide wall 431 close to the slag inlet 411.

[0066] Since the electric heating mechanism 200 is disposed transversely, during the rotation of the cleaning ring 400 , each slag inlet 411 will periodically move to the lower half and the upper half of the cleaning ring 400 .

[0067] When the slag inlet 411 moves to the upper part of the ring body 410, the corresponding cover 420 rotates toward the inside of the ring body 410 under the gravity of the counterweight 421 to open the slag inlet 411. When the slag inlet 411 moves to the lower part of the ring body 410, the corresponding cover 420 rotates toward the outside of the ring body 410 under the gravity of the counterweight 421 to close the slag inlet 411.

[0068] The inner thread direction is configured as follows: when the cleaning ring 400 is along Figure 4 When rotating in the middle K direction, the cleaning ring 400 moves toward the end of the heat transfer sleeve 300 away from the mounting seat 100 .

[0069] Based on this, during the rotation of the cleaning ring 400, the abutment block 430 can clean up the "debris" on the inner wall of the heat-conducting sleeve 300, and part of the cleaned "debris" can fall into the guide groove 433 located in the upper half of the ring body 410, and then be smoothly introduced into the slag inlet 411 (in an open state) located in the upper half of the ring body 410. Due to the existence of the guide groove 433, the cleaned "debris" can be prevented from falling to the side of the cleaning ring 400 close to the mounting seat 100.

[0070] Another part of the "debris" may fall directly to the bottom of the inner wall of the heat-conducting sleeve 300 during the cleaning process. The abutment block 430 can collect this part of the "debris" during the circumferential movement. Due to the existence of the guide groove 433, the "debris" can be confined within the range of the guide groove 433 and move with the abutment block 430. When the corresponding abutment block 430 moves toward the upper half of the ring body 410 and finally moves to the upper half, the "debris" carried by the guide groove 433 can smoothly fall into the guide groove 433, and finally fall into the slag inlet 411 along the guide groove 433. Figure 5 As shown. In this way, the collection of "debris" can be completed.

[0071] When the slag inlet 411 moves to the lower half of the ring body 410, the corresponding cover 420 rotates toward the outside of the ring body 410 under the gravity of the counterweight 421 to close the slag inlet 411, and the debris collected in the ring body 410 will not fall out again.

[0072] Through the above design, by cleaning the inner wall of the heat-conducting sleeve 300 at a set frequency, the electric heating effect of the heat-conducting sleeve 300 can be ensured, so that it can work continuously and stably.

[0073] Furthermore, the driving mechanism 500 is provided with a control module (not shown in the figure) and a detection module (not shown in the figure) for detecting driving resistance. The detection module is electrically connected to the control module.

[0074] The control module stores the lower limit value and the upper limit value of the driving resistance. When the driving resistance detected by the detection module is less than the lower limit value of the driving resistance, or the driving resistance detected by the detection module is greater than the upper limit value of the driving resistance, the control module issues a prompt and controls the driving mechanism 500 to stop working.

[0075] When the cleaning ring 400 is driven, the abutment block 430 abuts against the inner wall of the heat-conducting sleeve 300, which will bring a certain amount of additional resistance. The lower limit value and the upper limit value of the driving resistance can be determined according to the actual resistance situation.

[0076] When the detected driving resistance is less than the lower limit of the driving resistance, the abutment block 430 may be separated from the inner wall of the thermal sleeve 300 , which may be caused by the excessive inner diameter of the thermal sleeve 300 or the falling off of the elastic member 440 .

[0077] In the case where the detected driving resistance is greater than the upper limit value of the driving resistance, it may be caused by deformation of the heat-conducting sleeve 300 .

[0078] Through the above design, relevant risks can be promptly prompted, facilitating timely investigation, thereby ensuring subsequent normal use.

[0079] After cleaning, the cleaning ring 400 can be driven to rotate in the direction opposite to the K direction, so that the cleaning ring 400 moves toward the mounting seat 100, and finally moves the cleaning ring 400 from the heat conductive sleeve 300 to the positioning cylinder 130, so as to avoid interference with the subsequent electric heating process, and also reduce the impact of high temperature on the cleaning ring 400.

[0080] The elastic member 440 may be a spring, but is not limited thereto. The positioning column 110, the positioning cylinder 130, the rotating ring 120, the seat body 140, the blocking member 150, the rotating shaft 160, the driving rod 162, and the rear cover 170 are all made of heat-insulating materials.

[0081] In summary, the high-stability electric heating component for solar heat and power cogeneration provided in the embodiment of the present invention can further troubleshoot the problem of reduced heating performance and improve the continuous stability of heating. At the same time, it can also evaluate the heating safety and the health of components, thereby improving the overall efficiency of heating.

[0082] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. For those skilled in the art, the present invention may have various modifications and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
