Description

Technical Field

[0001] This utility model relates to the field of ground source heat pump technology, and in particular to a ground source heat pump waste heat utilization device. Background Technology

[0002] As a highly efficient and energy-saving air conditioning and heating system, the waste heat generated during the operation of a ground source heat pump has high recycling value. Ground source heat pump waste heat utilization devices usually transfer this waste heat to domestic water through heat exchange, and one of the components is a water tank used to store and heat domestic water.

[0003] During long-term operation of the device, as the water in the tank is repeatedly heated, mineral ions such as calcium and magnesium in the water will continuously precipitate and adhere to the inner wall and bottom of the tank, gradually forming hard scale. Scale has an extremely low thermal conductivity, and its continuous thickening will seriously hinder the transfer of heat from the heat exchange medium to the water, resulting in a significant decrease in the overall heat exchange efficiency of the device and an increase in unnecessary energy consumption.

[0004] Accumulated scale may detach under the impact of water flow. These detached blocky or granular scale particles will enter the water outlet pipe with the water flow. Due to the relatively small pipe diameter, these scale particles are very easy to accumulate and block at pipe bends, valves, or pump bodies. This not only affects the normal hot water supply, but in severe cases, it can even lead to abnormal pipe pressure, damage critical components such as the pump, and bring safety hazards and high maintenance costs. Existing devices generally lack an integrated structure for effectively cleaning the inside of the water tank. They usually rely on periodic shutdowns for manual chemical cleaning or mechanical scraping. The whole process is time-consuming and labor-intensive, and it affects the continuous and stable operation of the device.

[0005] Therefore, this utility model proposes a ground source heat pump waste heat utilization device to overcome the shortcomings of the prior art. Utility Model Content

[0006] In view of the problems existing in the ground source heat pump waste heat utilization device, such as scale buildup inside the water tank due to long-term use, lack of effective automatic cleaning structure, resulting in decreased heat exchange efficiency and high risk of pipe blockage, this utility model aims to provide a ground source heat pump waste heat utilization device with an improved structure that can effectively solve the above problems.

[0007] This utility model provides a ground source heat pump waste heat utilization device, including: a heat pump, a water tank, a waste heat collection box, a first circulation pipe, a second circulation pipe, and an extraction pump; the water tank is connected to an inlet pipe and an outlet pipe, the waste heat collection box is circulatedly connected to the water tank through the first circulation pipe and the second circulation pipe, the extraction pump is connected in series on the first circulation pipe or the second circulation pipe; and a cleaning mechanism is installed inside the water tank.

[0008] The cleaning mechanism includes a motor fixedly connected to the bottom of the water tank. The output end of the motor is rotatably connected to a drive shaft. The drive shaft passes through the bottom of the water tank and extends vertically into it. The upper end of the drive shaft is fixedly connected to a rotating shaft.

[0009] A support frame is fixedly connected to the rotating shaft. A second scraper for scraping the bottom of the water tank is threadedly connected to the bottom of the support frame. A first mounting plate is also fixedly connected to the support frame. The first mounting plate is engaged with a first scraper for scraping the inner wall of the water tank via a T-shaped block.

[0010] Preferably, the ground source heat pump waste heat utilization device further includes a remote control mechanism, which includes a support leg.

In order to realize the linkage control of the device, the control panel is electrically connected to the motor of the cleaning mechanism and the extraction pump to coordinate the waste heat circulation and cleaning work.

[0011] As a further limitation on the function of the remote control mechanism, the transmission module is a wireless communication module. The transmission module is used to receive instructions from the remote operating device and transmit them to the control panel. After receiving the instructions, the control panel can control the start and stop of the cleaning mechanism to achieve unmanned automatic cleaning management.

[0012] Preferably, to facilitate the placement of the remote control device, a second mounting plate is fixedly connected to the side wall of the control panel, and an arc-shaped clamp is fixedly connected to the second mounting plate. A friction pad is fixed on the inner side wall of the arc-shaped clamp. The arc-shaped clamp is preferably a C-shaped structure with elasticity.

Furthermore, the scraper is provided with a T-shaped groove that matches the T-shaped block, and the T-shaped block slides within the T-shaped groove to form a stable and detachable snap-fit ​​structure.

[0014] Preferably, the support frame has a high-strength structural design, the support frame includes a central sleeve fixedly sleeved with the rotating shaft and at least two support arms integrally formed and extending radially from the central sleeve, the mounting plate being fixedly connected to the end of the support arms to ensure sufficient rigidity during rotational scraping.

[0015] Preferably, to improve the fit and cleaning effect on the inner wall of the water tank, the first scraper is an elastic scraper with a certain curvature along its length. Its arc-shaped working surface design allows it to elastically contact the inner wall of the water tank when rotating, adapting to the curvature of the inner wall and scraping more thoroughly.

[0016] Preferably, in order to effectively clean the bottom of the water tank, the second scraper is a flat plate structure with a length smaller than the inner diameter of the water tank to ensure that it will not interfere with the inner wall of the water tank when rotating.

[0025] Working principle: When the heat pump unit 1 starts working, the waste heat collection box 9 absorbs heat. Under the action of the extraction pump 7, the heat is transferred to the water tank 4 through the second circulation pipe 10 and the first circulation pipe 8 to continuously heat the water in the water tank 4, utilizing the waste heat. Domestic water is injected into the water tank 4 through the inlet pipe 6, heated to the set temperature by the waste heat, and then discharged from the outlet pipe 5 to meet daily use. After working for a period of time, scale easily accumulates on the inner wall and bottom of the water tank 4. If it is not cleaned in time, it will cause blockage of the water supply pipe. Therefore, the motor 202 installed at the bottom of the water tank 4 will start periodically to drive the solid The drive shaft 203, fixed inside the water tank 4, rotates. The drive shaft 203 and the rotating shaft 201 are fixed together. The rotating shaft 201 rotates synchronously, which in turn drives the mounting plate 205 fixed on the support frame 208 to rotate. The mounting plate 205 drives the scraper 204 to rotate through the snap-fit ​​T-block 207, which scrapes and cleans the inner wall of the water tank 4 in all directions. The scraper 206 is threaded at the bottom of the support frame 208 to clean the bottom. The cleaning mechanism 2 solves the problem of scale clogging the water pipe caused by the lack of a cleaning device for water pipes in the existing equipment. Furthermore, the control panel 302 installed on the top of the support leg 301 can continuously collect the operating parameters of the ground source heat pump waste heat utilization device, including the water temperature of the water tank 4, the heat pump working load, the pipeline pressure, and the operating status of the cleaning mechanism 2, providing data support for operation and adjustment. The transmission module 304 fixed on the top of the control panel 302 provides convenience for remote operation. By remotely sending operation commands, the commands are received by the transmission module 304 and transmitted to the control panel 302, which then issues commands to adjust the equipment operating parameters, realizing remote control. An arc-shaped clamp 306 is installed on the mounting plate 305 on the right side of the control panel 302 to place the remote control device. The friction pad 303 fixed inside the arc-shaped clamp 306 increases the friction of the contact surface, ensuring that the remote control device is stable and does not fall off when stored, while avoiding wear on the surface of the device. The remote control mechanism 3 solves the problem that existing wireless remote operation of equipment requires going to the machine for each adjustment.
