The most commonly used method is to install a pressure transmitter on the pipeline to be tested. In order to provide power to the pressure transmitter, there are currently pressure transmitters that use solar panels as power sources.

[0003] The Chinese utility model patent authorization announcement document with announcement number CN210537114U announces a transmitter instrument case with a solar power supply, which basically consists of an instrument case and a boss, the boss is fixedly arranged at the upper end of the instrument case, a mounting hole is arranged at the center of the boss, and the mounting hole is communicated with the inner cavity of the instrument case, a round tube is vertically inserted in the mounting hole, the round tube extends upward through the mounting hole, a supporting plate is obliquely arranged on the upper end face of the round tube, and a solar cell panel is arranged on the upper end face of the supporting plate, a rechargeable battery is arranged in the instrument case, the rechargeable battery and the solar cell panel are electrically connected by the lead in the round tube, and screws are inserted in the side wall of the round tube, and the round tube and the boss are fixed by the screws. In the above-mentioned transmitter instrument case, the solar panel and the instrument case are reliably connected as one, but it has the following disadvantages: a through hole for installing the boss needs to be processed on the instrument case, which will affect the integrity of the instrument case; the sealing performance of the boss and the through hole and the round tube and the boss after matching must meet the requirements of field work, and a reliable sealing structure needs to be added, which will increase the production cost; the solar panel is inconvenient to disassemble and assemble when it needs to be repaired or replaced. Utility Model Content

[0004] The utility model aims to provide a split solar wireless pressure transmitter, which is used to solve the problem in the prior art that the solar cell panel is inconvenient to be disassembled and assembled when it needs to be repaired or replaced.

[0005] To achieve the above purpose, the solution of the utility model includes:

[0006] The utility model discloses a split solar wireless pressure transmitter, comprising an instrument case, a solar cell panel and a support base; the instrument case fixes the support base to the top of the instrument case through a throat clamp; the support base comprises a support plate which is used to fix and support the solar cell panel and which is at a first angle to the upper surface of the instrument case; the solar cell panel is directly or indirectly fixedly mounted on the support plate.

[0007] The pressure transmitter of the utility model comprises an instrument case, a solar panel and a support base. The instrument case and the support base located on the top of the instrument case are fixedly installed by a throat clamp, and the support base comprises a support plate which forms a first angle with the upper surface of the instrument case, and the solar panel is fixedly installed on the support plate. The throat clamp is used to reliably fix the support base for installing the solar panel on the outer surface of the instrument case, and no other installation structure is provided on the instrument case for installing the support base, thereby reducing the processing procedures of the instrument case and ensuring the integrity, sealing and explosion-proof performance of the instrument case. The structure is reasonable and reliable to use, which makes the installation and replacement of the solar panel more convenient and can reduce the installation and maintenance costs.

[0008] Furthermore, the support base also includes a fixing plate, which is fixed to one end of the fixing plate and forms a second angle with the fixing plate; the support base is fixed to the top of the instrument housing through the fixing plate.

[0009] Furthermore, the instrument case is cylindrical, and a platform for fixing the support seat fixing plate and parallel to the axis of the cylinder is arranged on the outer circumference of the instrument case, and the fixing plate has a connecting portion for matching and fitting with the platform.

[0010] The instrument case is a cylinder, and a platform for installing a fixing plate of a support seat is arranged on the outer circumferential surface of the cylindrical instrument case. The platform is arranged parallel to the axis of the cylinder, and a connecting portion for fitting with the platform is also arranged on the fixing plate. By arranging the platform on the outer circumferential surface of the cylindrical instrument case instead of directly installing the fixing plate of the support seat to the circular top of the instrument case, the reason is that the supporting surface formed by directly installing the fixing plate on the circular surface is very narrow and close to a line. This installation structure is not firm and may swing left and right. Therefore, by arranging the platform on the outer circumferential surface of the cylindrical instrument case and installing the fixing plate on the platform, the supporting surface of the platform for the fixing plate becomes larger, thereby avoiding the above-mentioned problem.

[0011] Furthermore, the connecting portion is a groove for accommodating the platform.

[0012] A groove is provided on the fixing plate for accommodating the mounting platform on the top of the instrument case. Since the mounting platform is added to the instrument case and is a raised structure relative to the instrument case, a stopping structure is formed after the groove on the fixing plate and the raised platform are adapted and installed. This stopping structure can make the installation more secure and will not cause relative movement.

[0013] Furthermore, an antenna mounting structure with through holes at both ends is embedded in the portion of the instrument housing along the radial direction of the cylinder close to the outer peripheral surface, and the antenna mounting structure forms a platform on one side facing the outer peripheral surface of the instrument housing.

[0014] An antenna mounting structure is embedded in the instrument case, and through holes are provided at both ends of the antenna mounting structure. This through hole structure reduces the processing steps of the instrument case and ensures the integrity, sealing and explosion-proof performance of the instrument case.

[0015] Furthermore, an antenna mounting seat for mounting the antenna is fixed on the through hole of the antenna mounting structure, and a wire for connecting the solar panel is also arranged on the antenna mounting seat, and the outward end of the wire is connected to the solar panel.

[0016] An antenna mounting base is installed on the through hole of the antenna mounting structure, and then the antenna is installed on the mounting base. At the same time, the mounting base is also provided with a wire for connecting the solar panel, and the outward end of the wire is connected to the solar panel; the wire connected to the solar panel shares the antenna mounting base with the antenna, and there is no need to open other channels on the instrument case to install the wire, thereby reducing the processing procedures for the instrument case and ensuring the integrity, sealing and explosion-proof performance of the instrument case.

[0017] Furthermore, a power interface is provided on a portion of the fixing plate that faces the supporting plate and avoids the supporting plate, the wire has a socket for connecting to the power interface, and the other end of the power interface is connected to the solar panel.

[0018] A power interface is provided on a portion of the fixing plate that is away from the supporting plate and faces the supporting plate to prevent rainwater from entering the power socket in rainy weather and damaging the solar panel. The wire has a socket for connecting to the power interface, which facilitates installation and removal of the solar panel.

[0019] Furthermore, it also includes a base plate for installing the solar panel, the support plate is fixedly installed on the solar panel through the base plate, and the base plate and the support plate are fixedly connected by bolts.

[0020] The solar panel is installed on the bottom plate, and then the bottom plate is installed on the support plate by bolts. The bolt installation is convenient for disassembly and installation of the bottom plate and the solar panel.

[0021] Furthermore, a display screen is arranged on one end surface of the instrument housing, and the other end surface is a battery cover.

[0022] A display screen is provided at one end of the cylindrical instrument housing to facilitate observation and data collection of the pressure transmitter, and the other end face is a battery cover to play a sealing role.

[0023] Furthermore, the first angle is 45°.

[0024] The angle formed by the support plate and the upper surface of the instrument housing is set to 45 degrees, so that rainwater or sand and gravel and other objects are not easy to stay on the solar panel, so as to prevent the normal operation of the solar panel from being affected.
