Description

Technical Field

[0001] The invention relates to the technical field of water-saving irrigation, and in particular to a pipe body fixing device. Background Art

[0002] Water-saving irrigation technology is an irrigation method that uses scientific management methods and advanced technical means in agricultural production to minimize water waste, increase crop yield and output value per unit of irrigation water, and improve water resource utilization efficiency. In the context of increasingly tight global water resources, water-saving irrigation technology is of great significance to ensuring the sustainable development of agricultural production. At present, the more mainstream water-saving irrigation technologies are mainly the following: pipeline water supply technology, sprinkler irrigation technology, micro-irrigation technology, infiltration irrigation technology, and above-film irrigation and below-film irrigation technology. And with the development of technology, different types of water-saving irrigation technologies have also been widely used in greenhouses, soilless cultivation, greenhouses, greening, gardening and other fields.

[0003] Drip irrigation pipe is an important irrigation device in water-saving irrigation technology. It can drip water and nutrients needed by crops evenly and slowly into the soil in the root zone of crops through a low-pressure pipeline system and an emitter installed on the drip irrigation capillary tube according to the water requirements of crops.

[0004] In plain areas, when drip irrigation pipes are laid on the surface, they can be fixed in position only by their own gravity. However, in desert areas, the climatic conditions are harsh, and strong winds and moving sand dunes will disturb the drip irrigation pipes laid on the surface, causing the pipes to shift and entangle. The existing drip irrigation pipe fixing parts include a clamp and a plug rod arranged at the bottom of the clamp. The drip irrigation pipe is clamped by the clamp, and then the plug rod is inserted into the ground to fix the drip irrigation pipe. However, due to the soft sandy soil in the desert area, this type of drip irrigation pipe fixing part is easy to sink during use. Moreover, this type of drip irrigation pipe has poor anti-overturning ability and will be pulled out of the sand in windy weather. These situations may cause the drip irrigation pipe to be blocked by sand and soil, requiring manual repair or replacement, which consumes manpower and material resources. Summary of the invention

[0005] In view of this, the present invention provides a pipe body fixing device to solve the problem that the existing drip irrigation pipe fixing parts will sink when used in desert areas and will be pulled out of the sand due to strong winds, causing the drip irrigation pipe to be blocked by sand and require maintenance.

[0006] In a first aspect, the present invention provides a pipe fixing device, comprising:

[0007] A clamping piece, the clamping piece is clamped on the outer wall of the tube body;

[0008] A ground inserting piece, one end of which is connected to the clamping piece, and the other end of which is inserted into the ground;

[0009] A contact piece, the contact piece is arranged at a portion of the ground inserting piece exposed to the ground, and a bottom surface of the contact piece contacts the ground;

[0010] An oblique plug-in unit is provided at the portion of the ground inserting member that is inserted into the underground.

[0011] Beneficial Effects

[0012] When the pipe body fixing device is used, the pipe body is first fixed by the clamping piece, and then the ground insert is inserted into the ground. The clamping piece can maintain a stable connection between the pipe body and the fixing device, and the ground insert can initially maintain stability under the action of the surrounding soil without shaking. When the abutment piece abuts against the ground, it means that the ground insert is in place, and the ground can continue to provide support for the abutment piece, so that the entire pipe body fixing device will not sink during use. The oblique plug-in inserted into the ground with the ground insert can improve the anti-overturning and anti-drifting capabilities of the pipe body fixing device. In the strong wind environment of the desert area, the fixing device remains stable and will not tilt, deviate or be pulled out of the sand. After the drip irrigation pipe is fixed by this fixing device, it can be firmly fixed when used in desert areas, and it is not easy for sand to block the drip irrigation pipe. The drip irrigation pipe can work continuously and stably, and has a longer service life.

[0013] In an optional embodiment, the clamping member includes: a clamping ring having a clamping opening for the tube body to enter and exit the clamping ring.

[0014] Beneficial Effects

[0015] The shape of the clamp is similar to that of the tube body, so it has better covering and fixing effect and can clamp the tube body better. The tube body can be fixed by entering the clamp from the clamp mouth, and no other locking mechanism is required at the clamp mouth. The overall structure is simpler and the manufacturing cost can be reduced.

[0016] In an optional embodiment, the bayonet is located on a side of the clamping ring facing the ground.

[0017] In an optional implementation, the ground insert includes: two pins, and the two pins are respectively connected to the ring bodies on both sides of the bayonet.

[0018] Beneficial Effects

[0019] The two pin tube body fixing devices are provided with more uniform force, and have better stability and balance.

[0020] In an optional implementation, the two pins are arranged in parallel.

[0021] Beneficial Effects

[0022] The pins encounter less resistance when inserted into the ground and are easier to insert into the ground.

[0023] In an optional embodiment, the pin includes: a bending portion and a vertical portion, one end of the bending portion is connected to the ring body on one side of the bayonet, and the other end is connected to the vertical portion, and the distance between the two vertical portions corresponding to the two pins is greater than the width of the bayonet.

[0024] Beneficial Effects

[0025] The distance between the two vertical parts is greater than the width of the bayonet, which makes it easier for the tube body to enter the clamping ring from between the two vertical parts, and the pins will not hinder the tube body and affect the installation of the tube body.

[0026] In an optional implementation, the two pins are arranged at an angle.

[0027] Beneficial Effects

[0028] When the two pins are arranged at an angle, the stability is good and the anti-tilting ability is better.

[0029] In an optional embodiment, the inclined plug-in is inclined toward the ground from one end connected to the pin to the other end.

[0030] Beneficial Effects

[0031] After the inclined plug is set, the pipe body fixing device will have a larger contact area with the soil in the ground, and the inclined plug and the ground plug can be subjected to forces in different directions exerted by the ground. In windy weather, the pipe body fixing device can remain stable in the soil and is not easily pulled out from the ground.

[0032] In an optional embodiment, the tube body fixing device further includes a lighting assembly, wherein the lighting assembly includes: a lighting component and a power supply mechanism, wherein the lighting component is disposed on the abutment component, and the power supply mechanism is electrically connected to the lighting component.

[0033] Beneficial Effects

[0034] At night, the lighting fixtures can also be used to display the route of the drip irrigation pipe, which also brings convenience to the work of the staff.

[0035] In an optional embodiment, the power supply mechanism includes: a solar panel and a battery, the solar panel is arranged above the clamping member, the battery is arranged on the ground plug-in member, and the solar panel is electrically connected to the battery, and the battery is electrically connected to the lighting member.

[0036] Beneficial Effects

[0037] By absorbing solar energy through solar panels to generate electricity for automatic power supply of lighting components, the natural resources in the area are rationally utilized and converted for utilization, thereby eliminating the need to provide additional power to the lighting components, saving resources and reducing costs.

[0047] The technical solution of the present invention will be described clearly and completely below in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0048] In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", etc., indicating the orientation or positional relationship, are based on the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and "third" are used for descriptive purposes only, and cannot be understood as indicating or implying relative importance.

[0049] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0050] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0051] Combine the following Figure 1 The embodiment of the present invention is described. This embodiment provides a pipe body fixing device, which is suitable for fixing a drip irrigation pipe, especially for firmly fixing the drip irrigation pipe in desert areas. In addition, this pipe body fixing device can also be expanded to fix other pipe bodies in the fields of agriculture and industry. In this embodiment, the pipe body is described by taking a drip irrigation pipe as an example.

[0052] The above-mentioned pipe body fixing device includes: a clamping member, a ground inserting member, an abutting member 3 and an oblique plug-in member 4. The clamping member is clamped on the outer wall of the pipe body. One end of the ground inserting member is connected to the clamping member, and the other end is inserted into the ground. The abutting member 3 is arranged at the part of the ground inserting member exposed to the ground 5, and the bottom surface of the abutting member 3 abuts against the ground 5. The oblique plug-in member 4 is arranged at the part of the ground inserting member inserted into the ground.

[0053] Specifically, the clamping piece is mainly used to clamp and fix the pipe body, so its shape characteristics must be compatible with the pipe body to clamp the pipe body. A part of the ground-inserting piece is inserted into the ground, and the other part is exposed to the ground 5 and is located above the ground 5. The clamping piece is connected to the top of the section of the ground-inserting piece exposed to the ground 5. After the ground-inserting piece is inserted into the ground, the drip irrigation pipe can be initially fixed. In addition, the bottom surface of the abutment piece 3 set on the part of the ground-inserting piece exposed to the ground 5 can abut against the ground 5, that is, when the ground-inserting piece is inserted into the ground, it stops when the abutment piece 3 abuts against the ground 5. The bottom surface of the abutment piece 3 is generally a plane. For example, the abutment piece 3 can be a flat plate, so that it can have a larger contact area with the ground 5, so that the pipe body fixing device can receive a larger support force from the ground 5. The oblique plug-in 4 will enter the ground with the ground-inserting piece. The setting angle of the oblique plug-in 4 is not along the vertical direction, that is, not along the direction perpendicular to the ground 5, but at a certain angle to the ground 5.

[0054] After the tube body is clamped and fixed by the clamping piece, the ground insert is inserted into the ground. The clamping piece can maintain a stable connection between the tube body and the fixing device, and the ground insert can initially maintain stability under the action of the surrounding soil without shaking. When the abutment 3 abuts against the ground 5, it means that the ground insert is in place, and the ground 5 can continue to provide support for the abutment 3, so that the entire tube body fixing device will not sink even when used in geologically soft sand. In addition, the oblique plug 4 inserted into the ground can improve the anti-overturning and anti-drifting capabilities of the fixing device. In the strong wind environment of the desert area, the tube body fixing device remains stable and will not be pulled out of the sand. After the drip irrigation pipe is fixed by this fixing device, it can be firmly fixed when used in desert areas, and it is not easy for sand to block the drip irrigation pipe. The drip irrigation pipe can work continuously and stably, and has a longer service life.

[0055] In one embodiment, the clamping member includes: a clamping ring 11, and the clamping ring 11 has a bayonet 12 for the tube body to enter and exit the clamping ring 11. Specifically, the clamping member is a circular ring with a notch, and the tube body enters and exits the clamping ring 11 through the notch. In addition, the diameter of the clamping ring 11 is equal to the outer diameter of the tube body, and the central angle corresponding to the bayonet 12 is less than 90°, so that the ring body can surround and limit the tube body to prevent the tube body from escaping from the bayonet 12. Of course, the clamping ring 11 itself needs to have a certain elasticity and be able to produce elastic deformation, so that the tube body can enter and exit the clamping ring 11 from the smaller bayonet 12. Therefore, in this embodiment, the clamping ring 11 is made of plastic material, which takes into account the requirements that the clamping ring 11 can be elastically deformed and the requirements of low economic cost.

[0056] The annular clamping piece is similar in shape to the tube body, so it has better covering and fixing effects and can clamp the tube body better. And because it can be elastically deformed, the tube body can be fixed after entering the ring, and there is no need to set other locking mechanisms at the bayonet 12. The overall structure is simpler and the manufacturing cost can be reduced.

[0057] In other embodiments, the clamping member may also be in other shapes, for example, the clamping member may be U-shaped, and the U-shaped clamping member also has an arc portion matching the tube body, so as to realize the clamping of the tube body. However, the use of the U-shaped clamping member requires a locking mechanism to be provided at the end of the clamping member, for example, a pin may be provided at the end of the clamping member, so that the tube body can be fixed in the clamping member.

[0058] The U-shaped clamping piece makes it easier to install and fix the pipe body, and in terms of material, the U-shaped clamping piece can be made of a material that is stronger and more durable than plastic, so the probability of damage to the clamping piece is lower and it is more durable.

[0059] In other embodiments, the clamping member may also be a pipe clamp, which generally consists of an upper and lower part, located on both sides of the pipe body, and then connected together by bolts and other connecting parts to complete the fixation of the pipe body.

[0060] As a commonly used pipe body fixing part, pipe clamps have been produced in a standardized manner and can be purchased and used directly, eliminating the process of processing and producing clamping parts.

[0061] In one embodiment, Figure 1 As shown, the bayonet 12 is located on the side of the clamp ring 11 facing the ground. Specifically, when the pipe body fixing device is used, it is inserted into the ground from above the ground 5, and the side of the clamp ring 11 facing the ground is also the lower side of the clamp ring 11.

[0062] In other embodiments, the bayonet 12 may also be located at other positions of the snap ring 11 , for example, the buckle may be located on the upper side, left side, right side, etc. of the snap ring 11 .

[0063] In one embodiment, Figure 1 As shown, the ground insert includes two pins 21 , and the two pins 21 are respectively connected to the ring bodies on both sides of the bayonet 12 .

[0064] Specifically, when the bayonet 12 is located on the side of the clamping ring 11 facing the soil, the two pins 21 can be respectively connected to the ring bodies on both sides of the bayonet 12. When the bayonet 12 is located at other positions of the clamping ring 11, the pins 21 are connected to the ring body at the bottom of the clamping ring 11.

[0065] Compared with setting a single pin 21, the stability and balance of the pipe body fixing device are better when two pins 21 are inserted into the ground.

[0066] In other embodiments, the number of the pins 21 in the ground insert may also be one, three, four, etc. When multiple pins 21 are provided, they may be provided in multiple directions and dimensions. For example, when four pins 21 are provided, two of them may be provided on the left and right sides of the clamp ring 11, and the other two may be provided on the front and rear sides of the clamp ring 11.

[0067] In one embodiment, Figure 1 As shown, the two pins 21 are arranged in parallel, that is, the two pins 21 are arranged along the vertical direction.

[0068] Specifically, the pin 21 includes: a bending portion 211 and a vertical portion 212. The bending portion 211 is a portion that transitions between the vertical portion 212 and the snap ring 11, and its shape may be arc-shaped. One end of the bending portion 211 is connected to the ring body on one side of the snap ring 12, and the other end is connected to the vertical portion 212. Moreover, the distance between the two vertical portions 212 corresponding to the two pins 21 is greater than the width of the snap ring 12, that is, the bending portion 211 bends and extends from the connection between the bending portion 211 and the ring body to the outside of the snap ring 12. In this embodiment, the distance between the two vertical portions 212 is equal to the inner diameter of the snap ring 11.

[0069] Through the transition of the bent portion 211 , the distance between the two vertical portions 212 is increased, so that the tube body can smoothly enter the clamping ring 11 from between the two vertical portions 212 without being blocked by the vertical portions 212 .

[0070] In other embodiments, the two pins 21 may also be arranged at an angle.

[0071] Specifically, the two pins 21 can also be arranged in an "eight" shape, and the distance between the upper ends of the two pins 21 is smaller than the distance between the lower ends of the two pins 21, that is, the distance between the ends of the two pins 21 connected to the clamping ring 11 is smaller, while the distance between the ends of the two pins 21 away from the clamping ring 11 is larger.

[0072] When the two pins 21 are arranged at an angle, the stability is more stable and the anti-tilting ability is better compared with the two pins 21 being arranged in parallel.

[0073] In one embodiment, the inclined plug 4 is inclined toward the ground 5 from one end connected to the plug pin 21 to the other end.

[0074] Specifically, each plug pin 21 is provided with an oblique plug 4. After being inserted into the ground, the oblique plug 4 is in an oblique upward posture. In this embodiment, the angle between the oblique plug 4 and the plug pin 21 is 45 degrees.

[0075] Of course, in other embodiments, the angle between the oblique plug 4 and the plug pin 21 may also be 30°, 60° or other angles.

[0076] In other embodiments, the inclined direction of the inclined plug-in 4 may also be inclined downward.

[0077] After the inclined plug 4 is arranged, the pipe body fixing device will have a larger contact area with the soil in the ground, and the inclined plug 4 and the ground insert can be subjected to forces in different directions exerted by the ground. In windy weather, the pipe body fixing device can remain stable in the soil and is not easy to be pulled out from the ground.

[0078] In one embodiment, the pipe body fixing device further comprises a lighting assembly, which comprises: a lighting member 61 and a power supply mechanism, wherein the lighting member 61 is arranged on the abutting member 3 , and the power supply mechanism is electrically connected to the lighting member 61 .

[0079] Specifically, the lighting element 61 can be a light-emitting diode, a small light bulb, etc. After being fixed to the abutment member 3, the lighting element 61 is powered by the power supply mechanism, and the lighting element 61 can emit light.

[0080] In desert areas where lighting conditions are poor, the lighting element 61 can be used to display the location of the drip irrigation pipe, thereby facilitating instructions for workers to perform maintenance work.

[0081] In one embodiment, the power supply mechanism includes: a solar panel 62 and a battery 63. The solar panel 62 is arranged above the clamping member, and the battery 63 is arranged on the ground inserting member, and the solar panel 62 is electrically connected to the battery 63, and the battery 63 is electrically connected to the lighting member 61.

[0082] Specifically, in desert areas, where there is sufficient sunlight during the day, the solar panel 62 can be used to absorb solar energy to generate electricity, and then the electrical energy is stored in the battery 63, and the battery 63 is used to power the lighting element 61 at night. The solar panel 62 is arranged above the clamping element, facing the sky to receive sunlight. The battery 63 can be arranged above the ground 5, or buried underground with the ground insertion element.

[0083] The solar panels 62 absorb solar energy to generate electricity for automatic power supply to the lighting device 61 , rationally utilizing and transforming the natural resources in the area, thereby eliminating the need to supply additional power to the lighting device 61 .

[0084] In other embodiments, the solar panel 62 may not be provided, and the lighting element 61 may be powered directly by the charged battery 63 to simplify the structure of the tube fixing device.

[0085] The following is a description of the use of the pipe fixing device:

[0086] A pipe body fixing device is arranged every 1-2 meters on the drip irrigation pipe. First, the pipe body is inserted into the clamp ring 11 from the clamping port 12, and the pipe body is clamped by the clamp ring 11. Then, the ground inserting piece is inserted into the ground until the abutting piece 3 abuts against the ground 5.

[0087] After the pipe body fixing device is set, the drip irrigation pipe is at a certain height from the ground 5, and does not directly contact the sand, so it is not easy to be directly blocked by the sand. During use, the abutment member 3 abuts against the ground 5 to prevent the device from sinking. The setting of the ground insertion member allows the device to be stably inserted into the ground even in windy weather, and will not be offset or even pulled out of the ground 5. Moreover, the direction of the drip irrigation pipe can be displayed through the lighting member 61 at night, which also brings convenience to the work of the staff.

[0088] Although the embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art may make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations are all within the scope defined by the appended claims.
