Description

Technical Field

[0002] Seagrass is a type of herbaceous higher plant, and seagrass beds formed by large areas of seagrass have multiple ecological functions, including regulating climate, purifying water quality, protecting coastlines, and promoting biodiversity. Seagrass farming, as an artificial cultivation technique for seagrass, mainly utilizes the intertidal zone or shallow sea areas for large-scale planting. During the seagrass farming process, it is necessary to harvest the seagrass regularly to control its growth density, prevent excessive growth, and maintain a healthy ecological balance in the seagrass bed.

[0003] Currently, seaweed harvesting is mostly done manually, with a small portion using mechanical methods. Existing seaweed harvesting machinery typically consists of a blade holder, a drive mechanism mounted on the holder, and a cutting blade. The drive mechanism powers the cutting blade to cut the seaweed, thus harvesting it. However, under prolonged harvesting operations, the cutting blades of this type of machinery become dull, affecting harvesting efficiency. In severe cases, the seaweed may not be completely cut and may become entangled in the cutting mechanism, damaging the machinery.

[0004] In conclusion, how to effectively solve the problem of seaweed being unable to be completely cut and becoming entangled in the cutting mechanism is a problem that urgently needs to be solved by those skilled in the art. Utility Model Content

Detailed Implementation

[0040] The core of this utility model is to provide a seaweed harvesting device that allows the cutting blade to remain sharp during long-term harvesting operations, preventing the seaweed from becoming entangled in the cutting mechanism due to incomplete cutting.

[0041] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0042] In one specific implementation, reference is made to... Figures 1 to 5 The seaweed harvesting device provided by this utility model includes a frame 100, a material collection mechanism 200, a cutting mechanism 400, and a sharpening mechanism 500.

[0043] The frame 100 has a cavity extending along a first direction; a receiving mechanism 200 is installed in the opening of the frame 100 on one side of the first direction. A cutting mechanism 400 and a sharpening mechanism 500 are jointly disposed in the opening of the frame 100 on the other side of the first direction; wherein, the cutting mechanism 400 includes a pair of cutting components 410 disposed opposite to each other on the frame 100, each cutting component 410 including a cutting blade 412, the two cutting blades 412 being able to swing relative to each other. The cutting component 410 may also include a motor 411, the motor 411 being mounted on the frame 100, the cutting blades 412 being connected to the output end of the motor 411, and the two cutting blades 412 of the two cutting components 410 being able to swing relative to each other under the driving action of the two motors 411. The sharpening mechanism 500 includes a pair of sharpening assemblies 510 disposed opposite to each other on the frame 100. Each sharpening assembly 510 includes a sharpening blade 512, which is retractable in a third direction and can press against the cutting edge 4121 of the cutting blade 412 when the cutting blade 412 is reset.

[0044] The first, second, and third directions mentioned above are perpendicular to each other, with the third direction corresponding to the height direction of frame 100, and the first direction being the direction of movement of frame 100. The first direction is as follows: Figure 1 The direction indicated by the middle arrow ab, the second direction is as follows Figure 1 The direction indicated by the middle arrow cd, the third direction, is as follows: Figure 1 The direction indicated by the middle arrow ef.

[0045] It should be understood that during the seaweed harvesting process using the above-mentioned seaweed harvesting device, the cutting mechanism 400 and the sharpening mechanism 500 can be considered as being located in front of the frame 100 in the direction of movement of the frame 100, and the collecting mechanism 200 can be considered as being located behind the frame 100. Thus, with the cooperation of the cutting mechanism 400 and the sharpening mechanism 500, the seaweed in front of the frame 100 is harvested, and the cut seaweed can be collected into the collecting mechanism 200 through the cavity of the frame 100.

[0046] It is also important to understand that, in the height direction of the frame 100, the sharpening mechanism 500 is located above the cutting mechanism 400. The swinging process of the two cutting blades 412 is as follows: In the initial separated state, the two cutting blades 412 are separated, and each of the two cutting blades 412 abuts against the two sharpening blades 512 respectively; then, the two cutting blades 412 move away from the sharpening blades 512 they abut against, and the two cutting blades 412 swing relative to each other to a crossed state; finally, the two cutting blades 412 return from the crossed state to the separated state, and the two cutting blades 412 return to abutting against the two sharpening blades 512 respectively. During the swinging process of the two cutting blades 412 from the initial separated state to the crossed state, the two cutting blades 412 can be used to cut seaweed.

[0047] Specifically, when the cutting blade 412 is in its initial separated state and its reset separated state, the grinding blade 512 is located between the cutting blade 412 and the support member 511, and the grinding blade 512 presses against the cutting edge 4121 of the cutting blade 412. Thus, during the process of the cutting blade 412 swinging from the separated state to the crossed state, there will be a brief sliding friction process between the cutting blade 412 and the grinding blade 512, which allows the grinding blade 512 to instantly grind the cutting edge 4121 of the cutting blade 412. Similarly, during the process of the cutting blade 412 resetting from the crossed state to the separated state, there will also be a brief sliding friction process between the cutting blade 412 and the grinding blade 512, which allows the grinding blade 512 to instantly grind the cutting edge 4121 of the cutting blade 412.

[0048] With the above-mentioned seaweed harvesting device, during the seaweed harvesting process, a sharpening blade 512 is set up so that the cutting blade 4121 of the cutting blade 412 is repeatedly sharpened by the sharpening blade 512 during the swinging process of the cutting blade 412. This keeps the cutting blade 412 sharp during long-term harvesting operations, thereby preventing the seaweed from getting tangled in the cutting mechanism 400 due to incomplete cutting. The sharp cutting blade 412 also helps to ensure efficient seaweed harvesting.

[0049] Below, we will refer to Figures 1 to 5 The various parts of the seaweed harvesting device described in this example embodiment will be explained in more detail.

[0050] In some embodiments, please refer to Figure 4 The grinding mechanism 500 also includes a support member 511, which is mounted on the frame 100, and the grinding blade 512 is telescopically disposed on the support member 511 along a third direction.

[0051] Specifically, the support member 511 includes a support plate 5111, a guide rod 5112, and an elastic element 5113. The support plate 5111 is connected to the frame 100, and in the third direction, the support plate 5111 is located on the side of the grinding blade 512 away from the cutting blade 412. The axial direction of the guide rod 5112 is parallel to the third direction, and the guide rod 5112 is movably inserted through the support plate 5111 in the third direction. The end of the guide rod 5112 near the cutting blade 412 is connected to the grinding blade 512, and the end away from the cutting blade 412 is provided with a limiting block 51121 to abut against the outside of the support plate 5111. The elastic element 5113 is sandwiched between the support plate 5111 and the grinding blade 512, so that the grinding blade 512 always tends to move closer to the cutting edge 4121 of the cutting blade 412.

[0052] In the aforementioned support member 511, the elastic element 5113 provides a continuous elastic force to the grinding blade 512, so that when the cutting blade 412 is reset, the grinding blade 512 can press against the cutting edge 4121 of the cutting blade 412; the guide rod 5112 can restrict the movement of the grinding blade 512 along the axial direction of the guide rod 5112, and also restrict the distance that the grinding blade 512 moves in the axial direction of the guide rod 5112. Thus, with the cooperation of the support plate 5111, the elastic element 5113 and the guide rod 5112, the cutting edge 4121 of the cutting blade 412 can be repeatedly ground.

[0053] Optionally, one end of the guide rod 5112 is connected to the grinding blade 512, and the other end of the guide rod 5112 is confined to the side of the support plate 5111 away from the grinding blade 512. Optionally, the other end of the guide rod 5112 is provided with a limiting block 51121, the size of which is larger than the diameter of the guide rod 5112 in the radial direction. By providing a limiting block 51121 at the other end of the guide rod 5112, the other end of the guide rod 5112 is confined to the side of the support plate 5111 away from the grinding blade 512, thereby limiting the movement distance of the grinding blade 512 in the axial direction of the guide rod 5112.

[0054] Optionally, the elastic element 5113 can be a spring, or the material of the elastic element 5113 can be rubber.

[0055] Specifically, the support plate 5111 has a third mounting hole that runs through a third direction, through which the guide rod 5112 passes.

[0056] Optionally, the support plate 5111 extends along a first direction, and each support plate 5111 is provided with two guide rods 5112; on each support plate 5111, along the first direction, an elastic element 5113 is located between the two guide rods 5112.

[0057] The cutting blade 412 is designed as a long strip, which facilitates cutting more seaweed at once. In addition, by configuring two guide rods 5112 on each support plate 5111 and arranging the two guide rods 5112 on both sides of the elastic member 5113 along the length of the support plate 5111, the stability of the support member 511 is improved, thereby providing stable elastic support for the grinding blade 512.

[0058] In some embodiments, the support plate 5111 extends along a first direction, with one end connected to the frame 100 and the other end provided with a first guide surface 51111. Exemplarily, the first guide surfaces 51111 on the two support plates 5111 are arranged opposite to each other, and the first guide surface 51111 is an inclined surface. The distance between the first guide surfaces 51111 on the two support plates 5111 gradually decreases along the first direction and in the direction from the support plate 5111 to the frame 100.

[0059] The first guide surface 51111 can guide the seaweed located in front of the frame 100, thereby guiding the seaweed to be cut into the space between the two cutting blades 412.

[0060] In some embodiments, the grinding blade 512 smoothly transitions from its adjacent side surfaces toward the surface facing the cutting blade 412 to form a convex arc-shaped grinding surface. The convex arc-shaped surface is used to grind the cutting edge 4121 of the cutting blade 412, which can not only prevent the grinding blade 512 from scratching the cutting blade 412, but also improve grinding stability and ensure grinding effect.

[0061] Optionally, the grinding blade 512 is a semi-cylinder, and the cylindrical surface of the grinding blade 512 is set towards the cutting blade 412. The grinding blade 512 uses its cylindrical surface to grind the cutting edge 4121 of the cutting blade 4122.

[0062] In one embodiment, both the grinding blade 512 and the cutting blade 412 are elongated, with the cutting edge 4121 on the cutting blade 412 extending along its length. One end of the cutting blade 412 is connected to the output end of the motor 411. The length directions of the grinding blade 512 and the cutting blade 412 are parallel to a first direction. When the grinding blade 512 is a semi-cylinder, its axial direction is parallel to the first direction to grind the cutting edge 4121 of the cutting blade 412 extending along the first direction.

[0063] In one embodiment, reference Figure 4 and Figure 5 As shown, in the height direction of the frame 100, two fourth mounting holes 102 are provided at the bottom of the frame 100, spaced apart along the second direction. The fourth mounting holes 102 are arranged through the frame 100 in the height direction, that is, the two ends of the fourth mounting holes 102 are respectively connected to the outer surface of the frame 100 and the cavity of the frame 100. The two motors 411 of the cutting mechanism 400 are mounted at the bottom of the frame 100 and are arranged one-to-one with the two fourth mounting holes 102. The motor body of the motor 411 is located in the cavity of the frame 100, and the output end of the motor 411 can pass through the frame 100 through the fourth mounting holes 102 to connect with the cutting blade 412.

[0064] It should be explained that the end of the cutting blade 412 connected to the output end of the motor 411 along the first direction is provided with a connecting shaft. The output end of the motor 411 is a rotating output shaft. The connecting shaft of the cutting blade 412 is connected to the output end of the motor 411 through a coupling. The connecting shaft of the cutting blade 412 is coaxially arranged with the output end of the motor 411. Thus, under the driving action of the motor 411, the output end of the motor 411 drives the connecting shaft of the cutting blade 412 to rotate, thereby causing the cutting blade 412 to swing.

[0065] It should also be explained that, along the height direction of the frame 100, a mounting bracket 140 is provided on the bottom outer wall of the frame 100. The mounting bracket 140 has bearing mounting holes, into which a bearing is installed. The bearing can be a deep groove ball bearing or an angular contact ball bearing. A journal is coaxially provided on the connecting shaft of the cutting blade 412, located at the end of the connecting shaft away from the motor 411 along the axial direction of the connecting shaft. The bearing mounted on the mounting bracket 140 is coaxially arranged with the journal of the cutting blade 412. The outer ring of the bearing is interference-fitted into the bearing mounting hole on the mounting bracket 140, and the inner ring of the bearing is interference-fitted into the journal of the cutting blade 412, ensuring that the output end of the motor 411 can smoothly drive the cutting blade 412 to swing, preventing the cutting blade 412 from shaking during swinging. The structure, function, and installation requirements of the aforementioned deep groove ball bearing and angular contact ball bearing are all existing technologies and will not be elaborated further here.

[0066] It should also be explained that the motors 411 of both cutting components 410 are reversible motors. By controlling the forward and reverse rotation of each motor 411, the rotation direction of the connecting shaft of each cutting blade 412 is controlled, thereby controlling the swing direction of each cutting blade 412, thus achieving relative swing control of the two cutting blades 412. For example, the motors 411 of both cutting components 410 perform alternating forward and reverse rotation operations, and when the motor 411 of one cutting component 410 rotates forward, the motor 411 of the other cutting component 410 rotates in reverse, so that the cutting blades 412 of the two cutting components 410 can achieve reciprocating swing. The structure and working principle of the aforementioned reversible motors are existing technology and will not be described in detail here.

[0067] In one embodiment, a sealing cover 150 is provided on the bottom inner sidewall of the frame 100 in the height direction. The bodies of the two motors 411 of the cutting mechanism 400 are located inside the sealing cover 150. The sealing cover 150 can seal and protect the motors 411 to prevent seawater from corroding the motors 411.

[0068] In some embodiments, such as Figure 1 , Figure 3 ,and Figure 5 As shown, it also includes a clamping mechanism 300, which includes a pair of clamping members 310 arranged opposite to each other. The clamping members 310 are installed in the opening on the other side of the frame 100 in the first direction. The clamping members 310 are located above the cutting mechanism 400 in the third direction. The two clamping members 310 can move towards each other or away from each other in the second direction.

[0069] It should be noted that the clamping mechanism 300 is located above the cutting mechanism 400 and the sharpening mechanism 500. Therefore, when harvesting seaweed using the aforementioned seaweed harvesting device, the two clamping members 310 of the clamping mechanism 300 are used to clamp the top of the seaweed, and the two relatively oscillating cutting blades 412 of the cutting mechanism 400 are used to cut the seaweed. Driven by the two motors 411 of the cutting mechanism 400, the two cutting blades 412 of the cutting mechanism 400 can oscillate relative to each other, allowing the two cutting blades 412 to swing from a separated state to a crossed state, and then back to a separated state. This continuous and reciprocating oscillation achieves the harvesting of seaweed.

[0070] With the above-mentioned seaweed harvesting device, during the seaweed harvesting process, the top of the seaweed is clamped by the two clamping members 310 of the clamping mechanism 300 to keep the seaweed in a taut state. The taut seaweed is cut by the two relatively swinging cutting blades 412. The cut seaweed can enter the collecting mechanism 200 through the cavity of the frame 100. With the cooperation of the clamping mechanism 300 and the cutting mechanism 400, the seaweed is more easily cut when subjected to the cutting force of the cutting blades 412, which helps to improve the harvesting efficiency.

[0071] In some embodiments, reference Figure 3 As shown, the frame 100 has two symmetrically arranged support arms 110 on the opening on the other side of the first direction, and two clamping members 310 are installed on the two support arms 110 in a corresponding manner; wherein, the support arms 110 extend along the first direction, and along the first direction, each support arm 110 has a guide frame 120 at the end away from the frame 100, and the guide frame 120 is used to guide the seaweed located in front of the frame 100.

[0072] By providing support arms 110 on the frame 100, mounting positions are provided for the clamping members 310, and the area between the two support arms 110 provides a space for the seaweed to be cut. In addition, by providing guide frames 120 on the support arms 110, the seaweed located in front of the frame 100 is guided, so that the seaweed to be cut enters between the two support arms 110 to be clamped by the two clamping members 310, while the seaweed that is not cut temporarily is guided along the guide frames 120 to both sides of the frame 100, so as to prevent the seaweed from getting tangled on the support arms 110 or the clamping members 310.

[0073] For example, the guide frame 120 includes a mounting plate 121, a guide plate 122, and a reinforcing plate 123. The mounting plate 121 is mounted on the support arm 110. The guide plate 122 and the reinforcing plate 123 are respectively connected to the two ends of the mounting plate 121 along a first direction. The guide plate 122 is set at an angle to the mounting plate 121, and the end of the guide plate 122 away from the mounting plate 121 is connected to the reinforcing plate 123. It should be noted that the connection between the guide plate 122 and the mounting plate 121 is closer to the end of the support arm 110 away from the frame 100; the distance between the guide plate 122 and the mounting plate 121 gradually increases along the first direction and in the direction from the support arm 110 to the frame 100.

[0074] In some embodiments, please refer to Figure 1 , Figure 3 and Figure 5 Each clamping component 310 includes a telescopic cylinder 311 and a clamping arm 312, with the clamping arm 312 connected to the output end of the telescopic cylinder 311. Two telescopic cylinders 311 are respectively mounted on two support arms 110, and two clamping arms 312 are located between the two support arms 110. Under the driving action of the two telescopic cylinders 311, the two clamping arms 312 can move towards each other or away from each other in a second direction. In the second direction, the guide frame 120 is located on the side of the support arm 110 away from the clamping arm 312.

[0075] It should be noted that the output end of the telescopic cylinder 311 (such as the electric cylinder or pneumatic cylinder) is a linear reciprocating motion output. The clamping arm 312 can be connected to the output end of the telescopic cylinder 311 via a coupling. Under the driving action of the telescopic cylinder 311, the clamping arm 312 can reciprocate in the second direction. Thus, under the control of the two telescopic cylinders 311, the two clamping arms 312 can move towards each other to clamp the seaweed, and the two clamping arms 312 can also move away from each other to release the seaweed. It should also be noted that when the two clamping arms 312 move towards each other to the clamping position, the two clamping arms 312 are close to each other, thus clamping the seaweed; when the two clamping arms 312 move away from each other to the initial position, the two clamping arms 312 separate, thus releasing the seaweed.

[0076] Optionally, a second mounting hole is provided on the support arm 110, which extends along the second direction. The body of the telescopic cylinder 311 is mounted on the side wall of the support arm 110 away from the clamping arm 312. The output end of the telescopic cylinder 311 can pass through the support arm 110 via the second mounting hole to connect with the clamping arm 312.

[0077] Optionally, the clamping arm 312 extends along a first direction, and along the first direction, a second guide surface 3121 is provided at the end of the clamping arm 312 away from the frame 100. The second guide surface 3121 is an inclined surface, and along the first direction and in the direction from the support arm 110 to the frame 100, the second guide surface 3121 gradually moves away from the support arm 110.

[0078] It should be noted that when the two clamping arms 312 move back to their initial positions, the second guide surface 3121 on the clamping arm 312 is located near the end of the support arm 110 away from the frame 100. The second guide surface 3121 can guide the seaweed located in front of the frame 100, thereby guiding the seaweed to be cut into the space between the two clamping arms 312.

[0079] In some embodiments, please refer to Figure 1 and Figure 5 The seaweed harvesting device also includes two power mechanisms 600. Each power mechanism 600 includes a first driver 610, a support base 620, a rotating frame 630, and a propeller 640. The first driver 610 and the support base 620 are mounted on the frame 100. The rotating frame 630 is rotatably mounted on the support base 620 and connected to the output end of the first driver 610. The propeller 640 is mounted on the rotating frame 630. The rotation axis of the rotating frame 630 is parallel to the second direction, and the rotation axis of the propeller 640 is perpendicular to the second direction.

[0080] It should be understood that a power mechanism 600 is provided on each of the two sides of the frame 100 along the second direction, and the power mechanism 600 is used to drive the frame 100 to move. Specifically, the propeller 640 includes a second driver, a hub 641, and a plurality of blades 642 disposed on the hub 641. The second driver is mounted on the rotating frame 630, the hub 641 is connected to the output end of the second driver, and the plurality of blades 642 are evenly spaced along the circumferential direction of the hub 641; wherein, the rotation axis of the hub 641 is perpendicular to the second direction.

[0081] It should be noted that when the propeller 640 is operating, the output of the second actuator can control the rotation of the propeller hub 641, which in turn drives multiple propeller blades 642 to rotate. As the multiple propeller blades 642 rotate in the water, they continuously push a large amount of water backward, thereby generating a forward force, i.e., propulsion, on the propeller blades 642, thus moving the frame 100. Furthermore, the rotation speed of the propeller hub 641 can be controlled by the output of the second actuator to control the magnitude of the propulsion. The structure and operating principle of the propeller 640 described above are existing technologies and will not be elaborated further here.

[0082] It should be explained that the output end of the second driver is a rotating output shaft, and the propeller hub 641 is connected to the output end of the second driver via a coupling. The propeller hub 641 and the output end of the second driver are coaxially arranged. Under the driving action of the second driver, the output end of the second driver drives the propeller hub 641 to rotate, thereby driving the multiple propeller blades 642 to rotate.

[0083] It should also be noted that, regarding the power mechanism 600 in this embodiment, the movement direction of the frame 100 can be adjusted through the cooperation of the propeller 640, the first driver 610, the support base 620, and the rotating frame 630. Specifically, under the driving action of the first driver 610, the rotating frame 630 can rotate relative to the support base 620 to adjust the orientation of the propeller blade 642, thereby adjusting the direction of the thrust generated by the propeller 640 and thus adjusting the movement direction of the frame 100.

[0084] Specifically, the rotating frame 630 is provided with shafts 631 on both sides along the second direction, and the axial direction of the shafts 631 is parallel to the second direction; wherein, the shaft 631 on one side of the rotating frame 630 along the second direction is rotatably connected to the support base 620, and the shaft 631 on the other side of the rotating frame 630 along the second direction is connected to the output end of the first driver 610.

[0085] It should be explained that the output end of the first driver 610 is a rotating output shaft. The shaft 631 on the other side of the rotating frame 630 along the second direction is connected to the output end of the first driver 610 via a coupling. The shaft 631 on the rotating frame 630 is coaxially arranged with the output end of the first driver 610. Under the driving action of the first driver 610, the rotating frame 630 is rotated via the output end of the first driver 610 to adjust the orientation of the blade 642. This embodiment does not limit the angle of rotation of the rotating frame 630 around the axial direction of the shaft 631.

[0086] In one embodiment, a battery 160 is installed on the frame 100. The battery 160 supplies power to the clamping mechanism 300, the cutting mechanism 400, and the power mechanism 600 installed on the frame 100 via wires. This embodiment does not impose specific restrictions on the layout of the battery 160 and the wires, as long as the battery 160 and the wires are not corroded by seawater and the seaweed harvesting device operates normally. Of course, the clamping mechanism 300, the cutting mechanism 400, and the power mechanism 600 can also be equipped with batteries to ensure the normal operation of the seaweed harvesting device.

[0087] In some embodiments, please refer to Figure 1 and Figure 2 The receiving mechanism 200 includes a receiving basket 210, a water pump 220, and a drain pipe 230. The receiving basket 210 is installed at the opening on one side of the frame 100 in the first direction, and the opening of the receiving basket 210 is connected to the cavity. The water pump 220 is installed on the frame 100. At least a part of the drain pipe 230 is located in the cavity of the frame 100, and the inlet of the drain pipe 230 is connected to the output end of the water pump 220. The outlet of the drain pipe 230 is set towards the receiving basket 210.

[0088] It should be explained that the water inlet of the aforementioned water pump 220 is located on the outside of the frame 100, and the water outlet of the aforementioned water pump 220 serves as the output end of the aforementioned water pump 220; the aforementioned collection basket 210 has a through hole 211 on its basket body. The water pump 220 can draw seawater from the outside of the frame 100 into the drain pipe 230, and then enter the cavity of the frame 100 through the outlet of the drain pipe 230. The seawater discharged from the outlet of the drain pipe 230 can flow towards the collection basket 210 under a certain water pressure, so that the seawater flowing towards the collection basket 210 can be used to collect the cut seaweed located in front of the frame 100 into the collection basket 210, and the seawater flowing into the collection basket 210 can flow out through the through hole 211 on the collection basket 210.

[0089] For example, in the height direction of the frame 100, a first mounting hole 101 is provided at the top of the frame 100. The first mounting hole 101 is provided through the frame 100 in the height direction, that is, the two ends of the first mounting hole 101 are respectively connected to the outer surface of the frame 100 and the cavity of the frame 100. The above-mentioned water pump 220 is installed on the top of the frame 100, and the body of the water pump 220 is located on the outside of the frame 100. The water inlet of the water pump 220 is located on the outside of the frame 100, and the drain outlet of the water pump 220 is set directly opposite the first mounting hole 101, or the drain outlet of the water pump 220 is installed at the first mounting hole 101 so that the inlet of the drain pipe 230 is connected to the drain outlet of the water pump 220.

[0090] Optionally, a connecting frame 130 is provided at the top of the frame 100. The body of the water pump 220 is connected to the connecting frame 130, and the water pump 220 is installed on the top of the frame 100 through the connecting frame 130. Two connecting frames 130 can be provided, with the two connecting frames 130 located on both sides of the first mounting hole 101 along the radial direction of the first mounting hole 101. Providing two connecting frames 130 can ensure that the water pump 220 is firmly installed on the frame 100.
