Description

Technical Field

[0001] This invention relates to the field of compression heating and cooling equipment technology, specifically a distributed solar heating and cooling control device. Background Technology

[0002] Distributed solar power refers to the use of solar photovoltaic power generation technology to distribute photovoltaic power generation systems around buildings or facilities to meet local electricity demand or supply power to the grid. Compared with centralized solar power plants, distributed solar power systems are more flexible and can be deployed in various scales and scenarios as needed. Heat pumps are heating and cooling control devices based on distributed solar power.

[0003] However, the air inlet filters of existing heat pumps are all vertically installed. In severe weather such as rain or snow, some rain and snow will fall into the heat pump and adhere to the filter surface, affecting the heat pump's efficiency and service life.

[0004] Therefore, a distributed solar heating and cooling control device is proposed to solve the above problems. Summary of the Invention

[0005] (a) Technical problems to be solved

[0006] To address the shortcomings of existing technologies, this invention provides a distributed solar heating and cooling control device. By using a waterproof cover to direct the air inlet downwards, and simultaneously using a lifting base to raise the height of the filter cylinder, rain and snow are less likely to enter the heat pump body. This prevents the filter cylinder from being too close to the ground and attracting dirt to its surface. A drive motor rotates the filter cylinder, and dust, rain, and snow on the filter cylinder surface are scraped together by the waterproof cover, exposing unblocked filter holes and further preventing clogging. This effectively protects the internal structure of the heat pump body, thus solving the problems mentioned in the background art.

Sleeves are rotatably connected to both sides of the shaft tube, and twist grooves are formed on the sleeves. Sliding blocks are fixedly connected to the bottom of both sides of the I-shaped plate along its length. The sliding blocks can slide on the twist grooves, thereby driving the sleeves to rotate. Reciprocating threads are formed on both sides of the drive rod along its length. Reciprocating rods are fixedly installed on the top of both sides of the I-shaped plate along its length, and the tops of the reciprocating rods are connected to the reciprocating threads. Radial tubes are fixedly installed on the sleeves along the diameter of the filter cartridge. Cleaning rods are fixedly connected to the ends of the two radial tubes away from the sleeves, and several brushes are evenly distributed on the cleaning rods.

[0012] Preferably, the brush is made of a flexible material that can penetrate the filter holes to push out blockages.

[0013] Preferably, the internal cleaning assembly is equipped with a collection and cleaning component, which includes a support rod. A rain and snow collection box is fixedly installed on the top of the support rod, and an impurity screen is fixedly installed on the rain and snow collection box. A multi-functional pump is fixedly installed in the inner cavity of the waterproof cover. A first connecting pipe and a second connecting pipe are fixedly connected between the input end of the multi-functional pump and the rain and snow collection box.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, the present invention provides a distributed solar heating and cooling control device, which has the following beneficial effects:

[0019] 1. This invention uses a waterproof cover to direct the air inlet downwards, while the lifting base raises the height of the filter cylinder, making it difficult for rain and snow to enter the heat pump body. This also prevents the filter cylinder from being too close to the ground and sucking dirt onto the surface. The drive motor can drive the drive rod to rotate in the forward, reverse, or alternating directions, thereby rotating the filter cylinder. Dust, rain, snow, etc. on the surface of the filter cylinder will be scraped together by the waterproof cover, exposing the unblocked filter holes and further preventing the filter holes from becoming clogged, effectively protecting the internal structure of the heat pump body.

[0020] 2. This invention uses a drive rod to rotate, causing a reciprocating screw drive rod to move linearly back and forth. A sliding block drives a sleeve to rotate back and forth through a torsion groove, causing the cleaning rod and brush to brush back and forth along the inner wall of the filter cylinder. Rain and snow are filtered through an impurity screen and collected in a rain and snow collection box. A multi-functional pump then pumps the collected rain and snow through a three-way pipe to a booster nozzle to flush the filter holes. The flushed water and dirt will automatically fall due to gravity. Pumping air can further improve the cleaning effect. Using the above structure, the filter holes are cleaned multiple times from the inside out, effectively preventing clogging and making it environmentally friendly.

[0021] 3. This invention achieves automatic cleaning and anti-clogging through the real-time temperature and weather data module and the blockage and temperature and weather judgment module on the controller, as well as the air volume sensor in the filter cartridge. It is simple and convenient. In addition, combined with the first connecting pipe, the second connecting pipe and the heating wire, it can deal with a variety of situations and improve the overall practicality of the device.

[0035] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments.

[0036] Example 1, please refer to Figures 1 to 5 As shown:

[0037] To address the problems mentioned in the technical solutions, this application provides a distributed solar heating and cooling control device, including a heat pump body 1, a lifting base 2 fixedly installed at the bottom of the heat pump body 1, a waterproof cover 3 fixedly connected to the air inlet of the heat pump body 1, the waterproof cover 3 being a fan-shaped structure with a 90-degree central angle, and the air inlet of the waterproof cover 3 facing vertically downwards, a central tube 4 fixedly installed at the air inlet of the waterproof cover 3, a filter cylinder 5 rotatably connected between the waterproof cover 3 and the central tube 4, a sealing ring being provided between the outer surface of the filter cylinder 5 and the inner wall of the waterproof cover 3, a plurality of filter holes 6 being evenly opened on the circumferential surface of the filter cylinder 5, and an internal cleaning component 7 being provided inside the filter holes 6;

[0038] The waterproof cover 3 is installed so that the air inlet faces downwards, and the height of the filter cartridge 5 is raised by the lifting base 2, so that rain and snow are not easy to enter the heat pump body 1, and the filter cartridge 5 is not too close to the ground and will suck dirt onto the surface.

[0039] The internal cleaning assembly 7 includes a drive frame 701 fixedly mounted on the shaft tube 4. A drive motor 702 is fixedly mounted on the top of the drive frame 701. A drive rod 703 is connected to the drive motor 702. A first gear 704 is fixedly connected to both ends of the drive rod 703. A second gear 705 is meshed with the first gear 704. The middle part of the second gear 705 is fixedly sleeved on both sides of the inner cavity of the filter cartridge 5 in the axial direction.

[0040] Specifically, the drive motor 702 can drive the drive rod 703 to rotate in the forward, reverse or alternating directions, thereby causing the filter cartridge 5 to rotate. Dust, rain and snow on the surface of the filter cartridge 5 will be scraped together by the waterproof cover 3, exposing the unblocked filter holes 6, thus ensuring its filtration effect.

[0041] Preferably, the number of teeth of the first gear 704 is less than the number of teeth of the second gear 705, and the two sides of the filter cylinder 5 in the axial direction are closed structures.

[0042] Furthermore, the internal cleaning assembly 7 also includes an I-shaped plate 706, which is slidably connected to the middle of the drive frame 701. Sleeves 707 are rotatably connected to both sides of the shaft tube 4. Twist grooves 708 are provided on the sleeves 707. Sliding blocks 709 are fixedly connected to the bottom of both sides of the I-shaped plate 706 along its length. The sliding blocks 709 can slide on the twist grooves 708, thereby driving the sleeves 707 to rotate. Reciprocating threads 710 are provided on both sides of the drive rod 703 along its length. Reciprocating rods 711 are fixedly installed on the top of both sides of the I-shaped plate 706 along its length. The top of the reciprocating rods 711 is connected to the reciprocating threads 710. Radial tubes 712 are fixedly installed on the sleeves 707 along the diameter of the filter cylinder 5. Cleaning rods 713 are fixedly connected to the ends of the two radial tubes 712 away from the sleeves 707. Several brushes 714 are evenly distributed on the cleaning rods 713.

[0043] Specifically, the rotation of the drive rod 703 causes the reciprocating thread 710 to drive the reciprocating rod 711 to reciprocate linearly. The sliding block 709, which is fixedly connected to the I-plate 706, reciprocates linearly. The sliding block 709 drives the sleeve 707 to reciprocate through the torsion groove 708, causing the cleaning rod 713 and the brush 714 to reciprocate along the inner wall of the filter cylinder 5 to clean the filter holes 6 from the inside. The I-plate 706 and the reciprocating rod 711 also serve as limiters.

[0044] Preferably, the brush 714 is made of a flexible material that can penetrate the filter holes 6 to push out blockages.

[0045] For a further embodiment two, please refer to Figures 5 to 7 As shown:

[0046] The internal cleaning component 7 is equipped with a collection and cleaning component 8, which includes a support rod 801. A rain and snow collection box 802 is fixedly installed on the top of the support rod 801. An impurity screen 803 is fixedly installed on the rain and snow collection box 802. A multi-functional pump 804 is fixedly installed in the inner cavity of the waterproof cover 3. A first connecting pipe 805 and a second connecting pipe 806 are fixedly connected between the input end of the multi-functional pump 804 and the rain and snow collection box 802. A switch valve 807 is provided on both the first connecting pipe 805 and the second connecting pipe 806. An electric heating wire is provided in the second connecting pipe 806. A three-way pipe 808 is fixedly connected to the output end of the multi-functional pump 804. The two output ends of the three-way pipe 808 are fixedly connected to the two ends of the shaft tube 4 respectively. The shaft tube 4, the sleeve 707, the radius tube 712, and the cleaning rod 713 are connected in sequence. Multiple pressurizing nozzles 809 facing the filter hole 6 are evenly connected on the cleaning rod 713.

[0047] Specifically, rain and snow can be filtered and collected into the rain and snow collection box 802 through the impurity screen 803, and then pumped out by the multi-functional pump 804. The collected rain and snow are transported through the three-way pipe 808 to the booster nozzle 809 to rinse the filter hole 6. The water and dirt after rinsing will fall automatically due to gravity and will not enter the heat pump body 1. The multi-functional pump 804 can pump and transport air and liquid. When there is no water in the rain and snow collection box 802, the cleaning effect can be further improved by pumping air.

[0048] Preferably, the horizontal area of ​​the rain and snow collection box 802 is larger than the horizontal area of ​​the heat pump body 1, which can shield the heat pump body 1.

[0049] Preferably, the first connecting pipe 805 and the second connecting pipe 806 are arranged in parallel, the middle part of the second connecting pipe 806 is located inside the heat pump body 1, and the middle part of the second connecting pipe 806 has a multi-segment S-shaped structure, thereby improving the cooling or heating effect.

[0050] For a further embodiment three, please refer to Figure 8 As shown:

[0051] The heat pump body 1 is equipped with a controller, which includes a real-time temperature and weather data module and a blockage and temperature and weather judgment module. The filter cartridge 5 is equipped with an air volume sensor. The blockage and temperature and weather judgment module can collect data from the air volume sensor and the real-time temperature and weather data module and make judgments. The drive motor 702, the multi-functional pump 804, the switch valve 807, and the heating wire are all electrically connected to the controller.

[0052] Specifically, the real-time temperature and weather data module can be a combination of a network unit and a weather APP to obtain the temperature and weather data of the current area in real time. The air volume sensor can obtain the data of the air volume passing through the filter hole 6. The network blockage and temperature and weather judgment module can determine whether the network is blocked by the air volume and whether there will be icing and network blockage or high temperature inside the heat pump body 1 by the temperature and weather data.

[0053] The working principle of all the content in the above embodiments is as follows:

[0054] During use, the air volume sensor and the real-time temperature and weather data module first acquire air volume, temperature, and weather data. When the blockage and temperature and weather judgment modules analyze and determine the blockage situation, the drive motor 702 is started. The drive motor 702 drives the first gear 704 and the second gear 705 to mesh and drive, causing the filter cylinder 5 to rotate. At the same time, the reciprocating thread 710 and the reciprocating rod 711 drive the I-shaped plate 706 to reciprocate linearly. The sliding block 709 slides along the twist groove 708, causing the sleeve 707 to drive the radius tube 712, the cleaning rod 713, and the brush 714 to swing back and forth, cleaning the filter holes 6 from the inside out.

[0055] When the network blockage and temperature weather judgment module analyzes and determines that the network is blocked and the temperature is within the normal operating range, the controller controls the switch valve 807 to open the first connecting pipe 805 and close the second connecting pipe 806, keeping the heating wire in the off state, and starts the multi-functional pump 804 to pump water or air through the first connecting pipe 805, the three-way pipe 808, the shaft pipe 4, the sleeve 707, the radius pipe 712, and the cleaning rod 713 to the booster nozzle 809, which sprays the water or air into the filter hole 6 to further clean the filter hole 6 from the inside out.

[0056] When the grid blockage and temperature weather judgment module analyzes and determines that the grid blockage or temperature is higher than the normal operating range, the temperature inside the heat pump body 1 will be higher than the ambient temperature. The controller controls the switching valve 807 to close the first connecting pipe 805 and open the second connecting pipe 806. The heating wire remains closed, and the multi-functional pump 804 is started to pump water or air through the second connecting pipe 806 to the booster nozzle 809. The low ambient temperature air or liquid cools the inside of the heat pump body 1 through the second connecting pipe 806, improving the heat dissipation effect and thus ensuring the efficient operation of the heat pump body 1.

[0057] When the filter blockage and temperature weather judgment module analyzes and determines that the filter is blocked, the freezing temperature has been reached, or there is rain or snow, the filter cylinder 5 will freeze and block the filter holes 6. The controller controls the switch valve 807 to close the first connecting pipe 805 and open the second connecting pipe 806. The heating wire is energized and the multi-functional pump 804 is started. The rain, snow and air are heated and sprayed out by the booster nozzle 809, thereby preventing the filter holes 6 from freezing and blocking.

[0058] It should be noted that, in this document, relational terms such as "first" and "second" are used only to distinguish one entity or operation from another, and do not necessarily require or imply any such actual relationship or order between these entities or operations. Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
