Abstract
Description
Technical Field
[0001] The present application relates to the technical field of crop seedling auxiliary devices, and in particular to a ground temperature heating device. Background Art
[0002] In the seedling raising work, when the external environment temperature is low or the temperature changes greatly, the growth of the seedlings is easily hindered. Therefore, it is usually necessary to heat the land so that the seedlings can grow in a suitable temperature environment.
[0003] Common low-temperature heating devices mainly include electric heating wires and controllers. The heating wires are buried 1-2 cm inside the ground and distributed in a U-shaped pattern. The controller controls the heating wires to heat the soil, thereby reducing the impact of low temperature environments on seedling growth.
[0004] In the environment for cultivating seedlings, the soil is relatively moist and the air is relatively humid. The controller is prone to damage if it is in a humid environment for a long time. Therefore, the stability of the geothermal heating device during use needs to be further improved. Utility Model Content
[0005] In order to improve the stability of a geothermal heating device during use, the present application provides a geothermal heating device.
[0006] The geothermal heating device provided in this application adopts the following technical solution:
[0007] A geothermal heating device comprises a geothermal heating wire laid in the soil and a controller for controlling the operation of the geothermal heating wire, and also comprises a protective shell, wherein the protective shell cover is arranged outside the controller to isolate the controller from the external environment.
[0008] By adopting the above technical solution, the protective shell blocks the controller from contacting the external environment, thereby preventing moisture in the air from invading the inside of the controller and causing damage to the electronic components inside the controller, thereby improving the stability of the controller during use.
[0009] Optionally, one side of the protective shell is open, and a rotatable blocking plate is provided at the opening of the protective shell. Rotating the blocking plate can make the side of the blocking plate away from its own axis approach or move away from the protective shell, and the controller is installed on the blocking plate.
[0010] By adopting the above technical solution, the opening and closing of the protective shell opening can be controlled by rotating the blocking plate. In the process of opening the protective shell opening, the blocking plate drives the controller to move to the outside of the protective shell at the same time, so as to facilitate the operation of the staff. When the controller is not in use, the blocking plate can be rotated to allow the controller to enter the protective shell and block the opening of the protective shell.
[0011] Optionally, a guiding assembly is provided on the blocking plate, and the guiding assembly includes a fixed column and a bracket, and the bracket is provided with an arc-shaped sliding groove coaxial with the rotation axis of the blocking plate, one end of the fixed column is fixedly connected to the inner wall of the protective shell, and the other end is fixedly inserted in the sliding groove and can slide along the length direction of the sliding groove.
[0012] By adopting the above technical solution, when the blocking plate is rotated, the fixed column slides relative to the bracket in the sliding groove along the length direction of the sliding groove, thereby guiding and limiting the rotation of the blocking plate, thereby improving the stability of the blocking plate during rotation.
[0013] Optionally, the guide components are arranged in multiple groups at intervals along a direction parallel to the rotation axis of the blocking plate.
[0014] By adopting the above technical solution, multiple groups of guide components further improve the stability of the blocking plate during rotation.
[0015] Optionally, a limiting assembly is provided on the fixed column, and the limiting assembly includes a limiting rod slidably connected to the fixed column along a length direction perpendicular to the sliding groove, and a limiting groove for inserting the limiting rod is opened on the side wall of the sliding groove, and the limiting groove is located at a position of the side wall of the sliding groove away from the blocking plate.
[0016] By adopting the above technical solution, the blocking plate is rotated to make the blocking plate rotate in the direction away from the protective shell. After the controller is located outside the protective shell, the limit rod is slid to insert the limit rod into the limit groove, so that the displacement of the bracket relative to the fixed column can be limited, and then the bracket can limit the blocking plate to prevent the blocking plate from rotating, which further facilitates the staff to operate the controller.
[0017] Optionally, the limiting assembly further includes an elastic member, which is mounted on the fixing column and is used to keep the limiting rod moving in a direction away from the fixing column.
[0018] By adopting the above technical solution, under the action of the elastic member, the limiting rod can be stably inserted into the limiting groove, thereby improving the stability of the limiting rod in limiting the movement of the bracket.
[0019] Optionally, a spherical surface is provided on the side of the limiting rod away from the fixing column.
[0020] By adopting the above technical solution, a force is applied to the sealing plate, and under the action of the spherical surface, the limit rod is subjected to a component force parallel to its own sliding direction, thereby overcoming the elastic force to disengage the limit rod from the limit groove, making it convenient for the staff to cover the sealing plate on the protective shell.
[0021] Optionally, a handle is provided on a side of the blocking plate away from its own axis.
[0022] By adopting the above technical solution, the handle provides a force application point for the staff, thereby facilitating the staff to rotate the blocking plate.
[0023] Optionally, a temperature sensor is further included, wherein the temperature sensor is disposed in a substrate for cultivating crops and is connected to a controller for transmitting temperature information to the controller.
[0024] By adopting the above technical solution, the temperature of the substrate used for cultivating crops is collected by the temperature sensor, and the controller controls the geothermal heating wire to automatically start or stop after receiving the temperature information, so as to stabilize the temperature of the substrate.
[0025] In summary, the present application includes at least one of the following beneficial technical effects:
[0026] 1. Set up a protective shell to prevent the controller from direct contact with external humid air, thereby reducing the damage of electrical components inside the controller and improving the stability of the controller during use.
[0027] 2. Turn the blocking plate to open the protective shell opening and move the controller out of the protective shell, making it easier for the staff to operate the controller. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION
[0032] The following is combined with Figure 1-3 This application is described in further detail.
[0033] The embodiment of the present application discloses a ground temperature heating device.
[0034] Reference Figure 1 and Figure 2A geothermal heating device includes a geothermal heating wire 1 buried in the soil, a controller 2 for controlling the operation of the geothermal heating wire 1, and a protective shell 3 covering the outside of the controller 2. The protective shell 3 is provided outside the controller 2 to prevent external moisture from entering the controller 2 to affect the operation of the electronic components inside the controller 2, thereby improving the stability of the controller 2 during use.
[0035] Reference Figure 2 and Figure 3 In this embodiment, the ground temperature heating wire 1 is a carbon fiber silicone heating wire, which is laid on the ground bed in a zigzag line. After the ground temperature heating wire 1 is laid, 1 cm thick fine soil is covered on the heating wire, and then the fine soil is covered with a ground film (not shown in the figure). During the seedling raising process, the seedling tray is placed on the ground film.
[0036] Reference Figure 2 and Figure 3 The ground temperature heating device also includes a temperature sensor 8, which is inserted into the seedling tray and electrically connected to the controller 2. The temperature sensor 8 collects the temperature of the substrate in the seedling tray and transmits it to the controller 2. The processing system inside the controller 2 receives the temperature information and then automatically controls the ground temperature heating wire 1 to work, so that the temperature of the substrate used for seedling cultivation in the seedling tray remains stable and meets the temperature requirements for crop growth.
[0037] Reference Figure 2 and Figure 3 The protective shell 3 is a square shell structure, and an opening is set on the side of the protective shell 3 facing away from the ground. A blocking plate 4 is set at the opening of the protective shell 3, and one side of the blocking plate 4 is rotatably connected to the protective shell 3. Rotating the blocking plate 4 can make the end of the blocking plate 4 away from its own rotation axis approach or move away from the protective shell 3, thereby realizing the control of the opening and closing of the protective shell 3. The controller 2 is installed on the blocking plate 4, and the blocking plate 4 is rotated to make the blocking plate 4 away from the protective shell 3. At the same time, the controller 2 follows the blocking plate 4 to move to the outside of the protective shell 3 for the staff to operate.
[0038] Reference Figure 2 and Figure 3 , a rotation guide assembly 5 is provided on the blocking plate 4, and the rotation guide assembly 5 includes a bracket 51 and a fixed column 52, and one end of the bracket 51 is welded to the side of the blocking plate 4 close to the protective shell 3. The fixed column 52 is arranged parallel to the rotation axis of the blocking plate 4, and one end is welded to the inner wall of the protective shell 3. An arc-shaped sliding groove 53 is provided on the bracket 51, and the axis of the sliding groove 53 coincides with the rotation axis of the blocking plate 4. One end of the fixed column 52 away from the protective shell 3 is inserted into the sliding groove 53, and can slide along the length direction of the sliding groove 53. In the process of rotating the blocking plate 4, the fixed column 52 slides in the sliding groove 53 relative to the bracket 51, limits and guides the rotation of the blocking plate 4, and improves the stability of the blocking plate 4 during rotation.
[0039] Reference Figure 2 and Figure 3 The guide components 5 can be arranged in multiple groups at intervals along a direction parallel to the rotation axis of the blocking plate 4. In this embodiment, two groups of guide components 5 are arranged corresponding to two inner side walls parallel to each other of the protective shell 3.
[0040] Reference Figure 2 and Figure 3 , a limiting assembly 6 is provided on the fixed column 52, and the limiting assembly 6 includes a limiting rod 61. A slot 62 is provided on the fixed column 52, and the limiting rod 61 is slidably connected in the slot 62 along a direction perpendicular to the length direction of the sliding slot 53. A limiting slot 63 is provided on the side wall of the sliding slot 53, and the limiting slot 63 is located at a position on the bracket 51 away from the blocking plate 4. After the blocking plate 4 is rotated to move the controller 2 to the outside of the protective shell 3, the sliding limiting rod 61 can make the end of the limiting rod 61 away from the fixed column 52 be inserted into the limiting slot 63, thereby limiting the sliding of the bracket 51. In this state, the bracket 51 can support and limit the blocking plate 4, prevent the blocking plate 4 from rotating, and thus facilitate the staff to operate the controller 2.
[0041] Reference Figure 2 and Figure 3 The limit assembly 6 also includes an elastic member 64, which is installed in the slot 62 and is used to keep the limit rod 61 moving in a direction away from the fixed column 52. In this embodiment, the elastic member 64 is a spring, one end of which is welded to the limit rod 61, and the other end is welded to the side wall of the slot 62. Under the elastic action of the elastic member 64, the limit rod 61 can be stably inserted into the limit groove 63, thereby improving the stability of the limit rod 61 in sliding the bracket 51. A spherical surface 65 is provided at one end of the limit rod 61 away from the fixed column 52, which applies a force to the blocking plate 4 to rotate the blocking plate 4. Under the action of the spherical surface 65, the limit rod 61 is subjected to a component force parallel to its own sliding direction. When the force applied by the staff to the blocking plate 4 is large enough, the limit rod 61 can overcome the elastic force of the elastic member 64 and disengage from the limit groove 63, canceling the limit on the bracket 51, making it convenient for the staff to store the controller 2 in the protective shell 3.
[0042] Reference Figure 2 and Figure 3 A handle 7 is provided at one end of the blocking plate 4 away from its own rotation axis to facilitate the staff to rotate the blocking plate 4. The handle 7 is arranged parallel to the blocking plate 4 to lengthen the force arm when rotating the blocking plate 4, so as to facilitate the staff to rotate the blocking plate 4.
[0043] Reference Figure 2 and Figure 3A sealing ring 9 may be provided between the sealing plate 4 and the protective shell 3 to improve the sealing performance after the sealing plate 4 is covered on the protective shell 3 , and further reduce the occurrence of moisture intrusion into the controller 2 .
[0044] The implementation principle of a geothermal heating device in an embodiment of the present application is: by providing a protective shell 3 on the outside of the controller 2, moisture in the air is blocked from invading the inside of the controller 2, thereby reducing the damage to the electronic components inside the controller 2 and improving the stability of the controller 2 during use.
[0045] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
