Detailed Implementation
[0019] 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.
[0020] Please see Figure 1-4 A mechanical negative pressure collection controller includes a control board 6 and a protective device disposed on the outer periphery of the control board 6.
[0021] In practical use, the control board 6 is usually installed next to the negative pressure collection well. The negative pressure collection well is mostly located underground or in an outdoor environment. The control board 6 needs to work continuously for a long time. In order to ensure the continuous operation of the control board 6 and reduce the probability of the control board 6 being damaged by environmental factors, a protective device for the control board 6 is designed.
[0022] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the protective device includes a housing 1 and a cover plate 2 disposed on the top of the housing 1. The inner wall of the bottom end of the housing 1 is provided with several mounting seats 14. The control board 6 is mounted on the mounting seats 14. The side wall of the housing 1 is provided with several wire holes 7. The outer wall of the housing 1 is provided with several mounting blocks 9 corresponding to the wire holes 7. The mounting blocks 9 are internally threaded with a Glenn connector 8. The inner wall of the housing 1 is also fixedly connected with a battery 12. The side wall of the housing 1 is also provided with a heat dissipation component that cooperates with the battery 12. The upper surface of the housing 1 and the lower surface of the cover plate 2 are both provided with mounting grooves. A sealing ring 4 is provided between the housing 1 and the cover plate 2. The sealing ring 4 is fixed in the mounting groove.
[0023] With the protective device in place, the control board 6 is installed on the mounting base 14 at the bottom of the housing 1, and the battery 12 is installed on the side wall of the cover plate 2. The cover plate 2 that matches the housing 1 is installed on the top of the housing 1. A sealing ring 4 is installed between the housing 1 and the cover plate 2, which can effectively seal the control board 6 inside the housing 1 and the cover plate 2, so that the control board 6 is not affected by the outside when it is working. The wires are passed from the outside of the housing 1 into the inside of the housing 1 and connected to the control board 6 through the wire hole 7 on the side wall of the housing 1 and the mounting block 9, so that the control board 6 can control the external equipment. The wires are passed through the Glen connector 8, and then the Glen connector 8 is threaded onto the mounting block 9. The Glen connector 8 can provide a sealing effect between the wires and the wire hole 7.
[0024] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the heat dissipation assembly includes a mounting sleeve 11 covering the outside of the battery 12. The side wall of the housing 1 is provided with heat dissipation holes. The inner and outer ends of the heat dissipation holes are respectively provided with a second heat dissipation block 13 and a first heat dissipation block 3. The first heat dissipation block 3 and the second heat dissipation block 13 are fixedly connected. The mounting sleeve 11 is fixedly connected to the second heat dissipation block 13.
[0025] By setting up the heat dissipation components, during installation, the first heat sink 3 and the second heat sink 13 are respectively installed at both ends of the heat dissipation hole, so that the first heat sink 3 and the second heat sink 13 completely cover the heat dissipation hole. Then, the mounting sleeve 11 containing the battery 12 is fixed to the second heat sink 13, so that the heat generated by the battery 12 when it is working can be well transferred to the first heat sink 3 and the second heat sink 13, and the heat is dissipated to the air outside the casing 1 through the first heat sink 3 and the second heat sink 13.
[0026] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the Glen connector 8 includes a fixed base 801 and a mounting cap 802 threaded onto one end of the fixed base 801. A first sealing ring 804 is fitted onto the inner wall of the mounting cap 802, and a second sealing ring 805 is fitted onto the inner wall of the first sealing ring 804. Lubricant 803 is applied between the first sealing ring 804 and the second sealing ring 805.
[0027] With the Gran connector 8, during installation, the wire is passed through the fixing base 801, the mounting cap 802, and the second sealing ring 805. The fixing base 801 is then threaded into the mounting block 9, causing the first sealing ring 804 and the second sealing ring 805 inside the mounting cap 802 to be compressed, starting to compress the wire until the second sealing ring 805 is completely against the wire. This effectively prevents liquids and gases from entering the housing 1. Lubricant 803 is applied between the first sealing ring 804 and the second sealing ring 805. When the mounting cap 802 is installed on the fixing base 801, it will rotate, and the first sealing ring 804 will rotate with the mounting cap 802. To prevent the rotation of the second sealing ring 805 from causing the wire to rotate and thus damaging the wire, the lubricant 803 effectively restricts the rotation of the second sealing ring 805, effectively protecting the wire.
[0028] Furthermore, referring to Figure 1-4 As shown, it is worth noting that a signal receiving box 5 is also provided on the side wall of the housing 1.
[0029] By setting up the signal receiving box 5, the signal receiver is installed inside the signal receiving box 5 during actual use. One end of the signal receiving box 5 protrudes through the side wall of the housing 1, which can effectively enhance the signal reception effect, reduce the delay, and also effectively protect the signal receiver.
[0030] Furthermore, referring to Figure 1-4 As shown, it is worth noting that the outer wall of the mounting base 14 is provided with a reinforcing ring 10, which is fixedly connected to the bottom of the housing 1. The housing 1, the reinforcing ring 10 and the mounting base 14 are integrally formed.
[0031] With the reinforcement ring 10 and the mounting base 14, the mounting base 14 provides an installation position for the control board 6 during actual use. The reinforcement ring 10 strengthens the mounting base 14 and prevents the control board 6 from bending during use, which would render the entire protection device unusable.
[0032] The mechanical negative pressure collection controller provided by this utility model has been described above. Specific preferred embodiments have been used to illustrate the principle and implementation of this utility model. These embodiments are only used to help understand the principle and core idea of this utility model. It should be noted that for those skilled in the art, the implementation schemes in the above embodiments can be further combined or replaced without departing from the design concept of this utility model, and several improvements and modifications can be made to this utility model. These improvements and modifications also fall within the protection scope of the claims of this utility model.
