Description

Technical Field

[0001] The utility model belongs to the technical field of vegetable greenhouses, and specifically relates to a water spraying device for vegetable greenhouses. Background Technique

[0002] The water spraying device for vegetable greenhouses is a device installed in vegetable greenhouses for spraying water on vegetables and the surrounding environment. In hot weather, by spraying water into the greenhouse, the evaporation of water will absorb heat, thereby reducing the temperature in the greenhouse, creating a suitable growth environment for vegetables, and preventing vegetables from suffering heat damage due to high temperature, such as leaf burns and growth stagnation.

[0003] Traditional water spraying devices for vegetable greenhouses usually directly use spray nozzles for spraying. However, after the spray nozzles are used, they are directly exposed, and dust is likely to fall into them, which may lead to nozzle blockage. After the nozzle is blocked, the water spraying is uneven or the normal water spraying cannot be carried out, making it difficult to effectively adjust the temperature and humidity in the growth environment of vegetables. Unstable humidity will cause the water balance of vegetables to be disrupted, affecting photosynthesis and metabolic activities, resulting in slow growth. Content of the Utility Model

[0004] To solve the problems raised in the above background technique, the utility model provides a water spraying device for vegetable greenhouses, which solves the problem that it is not convenient to protect the spray nozzles and is likely to cause nozzle blockage.

[0005] To achieve the above purpose, the utility model provides the following technical solution: A water spraying device for vegetable greenhouses includes a bracket. A plurality of groups of water spraying mechanisms are fixedly installed at the bottom of the bracket. A communicating pipe is connected to the bottom of the water spraying mechanism in a penetrating manner. A protective mechanism is fixedly installed at the bottom of the communicating pipe.

[0006] The protective mechanism includes a protective ring, an outer pipe, a return spring, a connecting block and a push rod. The protective ring is fixedly installed at the top of the outer pipe. The top end of the return spring is fixedly connected to the top end inside the outer pipe, and the bottom end of the return spring is fixedly connected to the top surface of the connecting block. A slider is fixedly connected to one side of the connecting block. The push rod is fixedly installed at the bottom of the slider.

[0007] Preferably, the bracket includes an arc-shaped plate, fixed rods and a conduit. The number of the fixed rods is set to two groups. Both groups of the fixed rods are fixedly connected to both sides of the arc-shaped plate. The conduit is fixedly installed in the middle of the arc-shaped plate.

[0008] Preferably, the water spraying mechanism includes a delivery pipe, a straight pipe and a stabilizing sleeve. The delivery pipe is connected to the straight pipe in a penetrating manner. The surface of the straight pipe is fixedly connected to the inner wall of the stabilizing sleeve.

[0009] Preferably, the top of the delivery pipe is connected to the bottom of the conduit in a penetrating manner. The input end of the communicating pipe penetrates through the stabilizing sleeve and is connected to the straight pipe in a penetrating manner.

[0010] Preferably, both ends of the straight pipe are fixedly connected with connecting rods. The number of the connecting rods is set to two groups, and both ends of the two groups of connecting rods are respectively connected with the inner side of the arc-shaped plate.

[0011] Preferably, an inner pipe is fixedly connected inside the outer pipe. Chutes adapted to the sliders are provided on both sides inside the inner pipe, and the protective ring is connected to the communicating pipe in a penetrating manner.

[0012] Preferably, a protective cover is fixedly connected to the bottom end of the push rod. A sealing ring is fixedly connected to the top of the protective cover, and the inner wall of the sealing ring is sleeved on the outer surface of the outer pipe.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] Through the settings of the protection mechanism and the water spraying mechanism, the present utility model can protect the nozzle, effectively avoiding the blockage of the nozzle. Water enters the conduit of the bracket from an external water source, and the water in the conduit flows to the straight pipe of the water spraying mechanism through the delivery pipe. The water accumulates in the straight pipe, and the pressure gradually increases. When the water pressure reaches a certain level, it overcomes the elastic force of the return spring, and the water pressure pushes the connecting block downward. The connecting block drives the slider to slide in the chute, and the movement of the slider opens the protective cover through the push rod. Since the protective cover is opened, water flows out of the inner pipe. The protective ring ensures the tight connection between the communicating pipe and the outer pipe, enabling the water to pass through smoothly. The water sprays out from the bottom of the inner pipe to spray water on the vegetables in the vegetable greenhouse. When the water supply stops, the water pressure in the straight pipe gradually decreases, and the protective cover closes. When the water supply stops, the water pressure in the straight pipe gradually decreases, and the elastic force of the return spring acts on the connecting block again, pushing the connecting block, the slider, and the push rod upward, so that the protective cover tightly covers the bottom of the outer pipe again. This automatic closing process can effectively prevent impurities such as dust from entering the water spraying mechanism, avoid the blockage of the nozzle, and enable the temperature and humidity in the vegetable growth environment to be effectively adjusted without causing the imbalance of vegetable moisture.

Detailed implementation manners

[0020] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0021] As Figures 1 to 4 shown, the present invention provides a water spraying device for a vegetable greenhouse, including a bracket 1. A plurality of groups of water spraying mechanisms 2 are fixedly installed at the bottom of the bracket 1. The bottom of the water spraying mechanism 2 is connected through a connecting pipe 3. A protection mechanism 4 is fixedly installed at the bottom of the connecting pipe 3;

[0022] The protection mechanism 4 includes a protection ring 41, an outer pipe 42, a return spring 43, a connecting block 44 and a push rod 45. The protection ring 41 is fixedly installed at the top of the outer pipe 42. The top end of the return spring 43 is fixedly connected to the top end inside the outer pipe 42, and the bottom end of the return spring 43 is fixedly connected to the top surface of the connecting block 44. One side of the connecting block 44 is fixedly connected to a slide block 46. The push rod 45 is fixedly installed at the bottom of the slide block 46.

[0023] Adopting the above solution: The arc plate 101 provides a stable foundation for the installation of other components, ensuring that the entire water spraying device will not be easily shaken or displaced by external forces during operation.

[0024] As Figures 1 to 4 shown, the bracket 1 includes an arc plate 101, fixed rods 102 and a conduit 103. The number of fixed rods 102 is set to two groups. Both groups of fixed rods 102 are fixedly connected to both sides of the arc plate 101. The conduit 103 is fixedly installed in the middle of the arc plate 101. The water spraying mechanism 2 includes a delivery pipe 21, a straight pipe 22 and a stabilizing sleeve 23. The delivery pipe 21 is connected through the straight pipe 22. The surface of the straight pipe 22 is fixedly connected to the inner wall of the stabilizing sleeve 23. The top of the delivery pipe 21 is connected through the bottom of the conduit 103. The input end of the connecting pipe 3 penetrates through the stabilizing sleeve 23 and is connected through the straight pipe 22.

[0025] Adopting the above solution: The delivery pipe 21 is connected in a through manner with the conduit 103 and the straight pipe 22, and is responsible for delivering the water in the conduit 103 to the straight pipe 22. It is an important channel for the water flow from the support 1 to the water spraying point. The protective ring 41 is fixedly installed at the top of the outer pipe 42 and is connected in a through manner with the connecting pipe 3, playing a role of connection and transition to ensure that the water can smoothly flow from the connecting pipe 3 into the outer pipe 42. The top end of the return spring 43 is fixedly connected to the top end inside the outer pipe 42, and the bottom end is fixedly connected to the top surface of the connecting block 44. When the water spraying device is not in use, the return spring 43 is in a compressed state, pushing the connecting block 44, the slider 46 and the push rod 45 upward, so that the protective cover 48 tightly covers the bottom of the outer pipe 42 to prevent dust from entering. When the water spraying device is in use, the pressure of the water overcomes the elastic force of the return spring 43, pushing open the protective cover 48 so that the water can be sprayed out.

[0026] As Figures 1 to 4 shown, both ends of the straight pipe 22 are fixedly connected with connecting rods. The number of connecting rods is set to two groups. The two ends of the two groups of connecting rods are respectively connected to the inner side of the arc-shaped plate 101. An inner pipe 47 is fixedly connected inside the outer pipe 42. Sliding grooves adapted to the sliders 46 are opened on both sides inside the inner pipe 47. The protective ring 41 is connected in a through manner with the connecting pipe 3. The bottom end of the push rod 45 is fixedly connected with a protective cover 48. A sealing ring is fixedly connected to the top of the protective cover 48, and the inner wall of the sealing ring is sleeved on the outer surface of the outer pipe 42.

[0027] Adopting the above solution: When the water spraying device is not in use, the protective cover 48 covers the bottom of the outer pipe 42 to prevent impurities such as dust from entering the connecting pipe 3 and the water spraying mechanism 2. When the water spraying device is in use, it is pushed open by the pressure of the water so that the water can be sprayed out.

[0028] The working principle and usage process of the present utility model: Fix the arc-shaped plate 101 of the support 1 at a suitable position inside the vegetable greenhouse through the fixing rods 102 on both sides to ensure that the support 1 is firm and stable. Fix the conduit 103 in the middle of the arc-shaped plate 101 as the main channel for the water flow;

[0029] When no water is sprayed, the return spring 43 of the protection mechanism 4 is in a compressed state. The elastic force of the return spring 43 acts on the connecting block 44. The connecting block 44 drives the push rod 45 through the slider 46, so that the protective cover 48 at the bottom of the push rod 45 tightly covers the bottom of the outer pipe 42. The sealing ring on the top of the protective cover 48 is tightly sleeved on the outer surface of the outer pipe 42 to prevent impurities such as dust from entering;

[0030] Water enters the conduit 103 of the support 1 from an external water source. The water in the conduit 103 flows through the delivery pipe 21 to the straight pipe 22 of the water spraying mechanism 2. The water accumulates in the straight pipe 22, and the pressure gradually increases. When the water pressure reaches a certain level, it overcomes the elastic force of the return spring 43. The water pressure pushes the connecting block 44 downward. The connecting block 44 drives the slider 46 to slide in the chute. The movement of the slider 46 causes the protective cover 48 to open through the push rod 45. Since the protective cover 48 opens, the water flows out from the inner pipe 47. The protective ring 41 ensures a tight connection between the connecting pipe 3 and the outer pipe 42, allowing the water to pass through smoothly. The water sprays out from the bottom of the inner pipe 47 to perform a water spraying operation on the vegetables in the vegetable greenhouse.

[0031] When the water supply stops, the water pressure in the straight pipe 22 gradually decreases, and the protective cover 48 closes. The elastic force of the return spring 43 acts on the connecting block 44 again, pushing the connecting block 44, the slider 46, and the push rod 45 upward. The push rod 45 drives the protective cover 48 to tightly cover the bottom of the outer pipe 42 again, restoring the protective state.

[0032] It should be noted that in this text, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device comprising a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
