In order to reduce energy waste and improve energy utilization efficiency, waste heat recovery machines are often used to recover the waste heat emitted by the steam turbine, and convert the heat energy into other forms of energy through equipment such as heat exchangers.

[0003] When the existing waste heat recovery device of the steam turbine of a power plant is fixed at a specified position, it is generally fixed by clamping a universal wheel so that the waste heat recovery device is fixed at the specified position and will not move. After a long period of use, the universal wheel cannot be clamped and fixed, so that the waste heat recovery device will move during waste heat recovery, resulting in the inability to recover waste heat. Therefore, improvement is needed. Summary of the invention

[0033] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0034] like Figures 1 to 9 As shown, a waste heat recovery device for a steam turbine in a power plant includes a waste heat recovery machine 10, a moving mechanism 20, a mounting mechanism 30 and a fixing mechanism 40, wherein:

[0035] The moving mechanism 20 includes a mounting tube 201, which is provided with a pair of mounting tubes 201 and is arranged parallel to each other. A pair of moving wheels 202 are symmetrically installed at the bottom of the mounting tube 201. The waste heat recovery machine 10 can be easily moved to a designated position through the moving mechanism 20.

[0036] The mounting mechanism 30 is disposed above the moving mechanism 20 and includes a shock-absorbing pad 305 and a pressing plate 307. The waste heat recovery machine 10 is quickly mounted above the moving mechanism 20 through the shock-absorbing pad 305 and the pressing plate 307.

[0037] The fixing mechanism 40 is disposed below the moving mechanism 20 and includes a glass suction cup 406 , through which the moving mechanism 20 is adsorbed onto a smooth ground surface, thereby quickly fixing the waste heat recovery machine 10 to a designated position.

[0038] In this embodiment, a pair of hinged seats 203 are connected to the side of the installation tube 201, and a pair of hinged bars 204 are hinged in parallel on each hinged seat 203. All hinged bars 204 are hinged to the installation frame 205. A pair of telescopic rods 207 are symmetrically arranged on the front and rear sides of the installation frame 205. The two ends of each telescopic rod 207 are correspondingly connected between the installation tubes 201 on both sides, and each telescopic rod 207 is equipped with a compression spring 208. When the waste heat recovery machine 10 is placed on the top of the installation frame 205, the installation frame 205 will be lowered by the pressure of the waste heat recovery machine 10, and the hinged bars 204 on the left and right sides will expand outward, thereby expanding the distance between the left and right installation tubes 201, until the pair of fixed pipes 101 at the bottom of the waste heat recovery machine 10 are parallel to the top of the left and right installation tubes 201. Move the waste heat recovery machine 10 away from the top of the installation frame 205, and the hinge bars 204 on the left and right sides will be retracted toward the middle under the action of the compression spring 208, thereby reducing the distance between the left and right installation tubes 201 until the installation frame 205 rises to the initial height, so as to reduce the space occupied by the mobile mechanism 20 when idle.

[0039] In this embodiment, the interior of the mounting tube 201 is coaxially connected to a lead screw 301 via a pair of bearing seats 302, the front and rear sections of the lead screw 301 have the same pitch and opposite rotation directions, both sections of the thread are connected to a slider 304 via a lead screw nut 303, and a shock-absorbing pad 305 is installed on the top surface of the slider 304, a pair of mounting grooves 201a are symmetrically provided at both ends of the mounting tube 201, two pairs of mounting strips 306 are hinged in parallel on both sides of each mounting groove 201a, and a clamping plate 307 is hinged on the top of the pair of mounting strips 306, the end face of the slider 304 is connected to an L-shaped linkage strip 309, and the upper part of the linkage strip 309 is slidably connected to the adjacent clamping plate 307. By rotating the lead screw 301 counterclockwise, the front and rear sliders 304 can be driven to approach each other, and then the top ends of the front and rear shock-absorbing pads 305 are correspondingly inserted into the fixed grooves 101a at both ends of the fixed tube 101. At the same time, the front and rear clamping plates 307 are correspondingly driven to deflect downward and inward through the front and rear linkage bars 309, and the front and rear clamping plates 307 are correspondingly pressed against the two ends of the fixed tube 101, so as to achieve the rapid installation of the waste heat recovery machine 10 above the moving mechanism 20. By rotating the lead screw 301 clockwise, the front and rear sliders 304 can be driven to move away from each other, and then the front and rear clamping plates 307 are correspondingly driven to deflect upward and outward through the front and rear linkage bars 309, and the front and rear clamping plates 307 are away from the ends of the fixed tube 101. At the same time, the front and rear shock-absorbing pads 305 can be driven to move away from the fixed grooves 101a at both ends of the fixed tube 101.

[0040] In this embodiment, the bottom surface of the mounting frame 205 is horizontally connected to a mounting bar 401, and a pair of mounting plates 403 are symmetrically arranged below the mounting bar 401. A plurality of connecting rods 404 are centrally connected to the upper side of the mounting plate 403, each connecting rod 404 is slidably connected to the mounting bar 401, and each connecting rod 404 is provided with a compression spring 2 405, and a pair of glass suction cups 406 are symmetrically connected to the lower side of the mounting plate 403. By pressing down the mounting bar 401, the lower surface of the glass suction cup 406 can be attached to the smooth ground, and then by pushing the buckle on the glass suction cup 406 downward, the glass suction cup 406 can be adsorbed on the smooth ground, thereby quickly fixing the mobile mechanism 20 and the installed waste heat recovery machine 10 to the specified position. By pushing the glass suction cup 406 upward, the glass suction cup 406 can be driven away from the smooth ground.

[0041] In this embodiment, a rubber pad 206 is attached to the top surface of the mounting frame 205. The rubber pad 206 can prevent the top surface of the mounting frame 205 from directly contacting the bottom surface of the waste heat recovery machine 10, and even if the waste heat recovery machine 10 vibrates during operation, the vibration will not be transmitted to the mounting frame 205.

[0042] In this embodiment, a rubber sheet 308 is attached to the bottom surface of the pressing plate 307. The rubber sheet 308 can increase the friction between the bottom surface of the pressing plate 307 and the bottom of the waste heat recovery machine 10.

[0043] In this embodiment, the rear end of the lead screw 301 is keyed to a hand wheel 309. The lead screw 301 can be easily rotated by the hand wheel 309.

[0044] In this embodiment, a pair of reinforcing plates 402 are fixed between the installation frame 205 and the installation bar 401. The reinforcing plates 402 can increase the connection strength between the installation frame 205 and the installation bar 401.

[0045] The working principle of this power plant steam turbine waste heat recovery device:

[0046] Place the waste heat recovery machine 10 on the top of the installation frame 205. The installation frame 205 will drop due to the pressure of the waste heat recovery machine 10, and the hinge bars 204 on the left and right sides will expand outward, thereby expanding the distance between the left and right installation pipes 201, until a pair of fixed pipes 101 at the bottom of the waste heat recovery machine 10 are parallel to the top of the left and right installation pipes 201, and the waste heat recovery machine 10 can be easily transferred to the specified position through the moving mechanism 20.

[0047] The front and rear sliders 304 are driven to approach each other by rotating the lead screw 301 counterclockwise, and then the top ends of the front and rear shock-absorbing pads 305 are correspondingly inserted into the fixing grooves 101a at both ends of the fixing tube 101. At the same time, the front and rear clamping plates 307 are correspondingly driven to deflect downward and inward through the front and rear linkage bars 309, and the front and rear clamping plates 307 are correspondingly clamped to the two ends of the fixing tube 101, thereby realizing the rapid installation of the waste heat recovery machine 10 above the moving mechanism 20.

[0048] By pressing down the mounting strip 401, the lower surface of the glass suction cup 406 can be pressed against the smooth ground, and then by pushing down the buckle on the glass suction cup 406, the glass suction cup 406 can be adsorbed on the smooth ground, thereby quickly fixing the moving mechanism 20 and the installed waste heat recovery machine 10 to the designated position.

[0049] Therefore, the embodiments disclosed above are only illustrative in all aspects and are not exclusive. All changes within the scope of the present invention or within the scope equivalent to the present invention are included in the present invention.
